                  Each  party  agrees as  follows  for the  benefit of the other
parties  and for the equal and ratable  benefit of the holders of the  Company's
6.375% Senior Notes due 2015:

                   DEFINITIONS AND INCORPORATION BY REFERENCE

        SECTION 1.01.  DEFINITIONS.

                  "Additional   Securities"  means,  subject  to  the  Company's
compliance with Section  4.09(a),  6.375% Senior Notes due 2015 issued from time
to time  after the Issue  Date  under the terms of this  Indenture  (other  than

Exchange  Securities  or  Private  Exchange  Securities  issued  pursuant  to an
exchange offer for other Securities outstanding under this Indenture).

                  "Adjusted  Consolidated  EBITDA"  means the  Consolidated  Net
Income of the Company and its Restricted  Subsidiaries for the Reference Period,
(a) increased (to the extent deducted in determining Consolidated Net Income) by
the sum,  without  duplication,  of: (i) all income and state franchise taxes of
the Company and its Restricted  Subsidiaries  paid or accrued  according to GAAP
for such period (other than income taxes attributable to extraordinary,  unusual
or non-recurring gains or losses);  (ii) all interest expense of the Company and
its  Restricted  Subsidiaries  paid or accrued in accordance  with GAAP for such
period  (including  amortization  of original issue discount or premium);  (iii)
depreciation and depletion of the Company and its Restricted Subsidiaries;  (iv)
amortization of the Company and its Restricted Subsidiaries  including,  without
limitation,  amortization  of  capitalized  debt  issuance  costs;  (v) any loss
realized  in  accordance  with  GAAP upon the sale or other  disposition  of any
property,  plant or  equipment  of the  Company or its  Restricted  Subsidiaries
(including  pursuant  to any  Sale/Leaseback  Transaction)  which is not sold or
otherwise  disposed of in the ordinary  course of business and any loss realized
in accordance with GAAP upon the sale or other  disposition of any Capital Stock
of any Person;  (vi) any loss  realized in  accordance  with GAAP from  currency
exchange  transactions  not in the ordinary  course of business  consistent with
past practice;  (vii) any loss net of income taxes  realized in accordance  with

with the prepayment of any Indebtedness;  and (ix) any other non-cash charges to
the extent  deducted  from  Consolidated  Net Income and (b)  decreased  (to the
extent  included in determining  Consolidated  Net Income) by the sum of (i) the
amount of deferred  revenues that are amortized  during the Reference Period and
are attributable to reserves that are subject to Volumetric  Production Payments
and (ii) amounts recorded in accordance with GAAP as repayments of principal and
interest pursuant to Dollar-Denominated Production Payments.




                                                                               2


                  "Adjusted  Consolidated  EBITDA Coverage Ratio" means, for any
Reference  Period,  the ratio on a pro forma basis of (a) Adjusted  Consolidated
EBITDA for the Reference  Period to (b) Adjusted  Consolidated  Interest Expense
for such Reference Period;  PROVIDED, that, in calculating Adjusted Consolidated
EBITDA  and  Adjusted  Consolidated  Interest  Expense  (i)  acquisitions  which
occurred during the Reference  Period or subsequent to the Reference  Period and
on or prior to the date of the transaction  giving rise to the need to calculate
the Adjusted  Consolidated  EBITDA Coverage Ratio (the "Transaction Date") shall
be assumed to have occurred on the first day of the Reference  Period,  (ii) the
incurrence of any  Indebtedness  (including  the issuance of the  Securities) or
issuance of any Disqualified  Stock during the Reference Period or subsequent to
the Reference Period and on or prior to the Transaction Date shall be assumed to
have occurred on the first day of such Reference Period,  (iii) any Indebtedness
that had been outstanding during the Reference Period that has been repaid on or
prior to the  Transaction  Date shall be  assumed to have been  repaid as of the
first day of such  Reference  Period,  (iv) the Adjusted  Consolidated  Interest
Expense  attributable  to  interest  on any  Indebtedness  or  dividends  on any
Disqualified  Stock  bearing a floating  interest  (or  dividend)  rate shall be
computed on a pro forma basis as if the rate in effect on the  Transaction  Date
were the average rate in effect  during the entire  Reference  Period and (v) in
determining the amount of Indebtedness  pursuant to Section 4.09, the incurrence
of  Indebtedness  or issuance of  Disqualified  Stock giving rise to the need to
calculate the Adjusted Consolidated EBITDA Coverage Ratio and, to the extent the
net  proceeds  from the  incurrence  or  issuance  thereof  are  used to  retire
Indebtedness, the application of the proceeds therefrom shall be assumed to have
occurred on the first day of the Reference Period.

                  "Adjusted  Consolidated  Interest Expense" means, with respect
to the Company and its Restricted  Subsidiaries,  for the Reference Period,  the
aggregate  amount (without  duplication) of (a) interest  expensed in accordance
with GAAP  (including,  in  accordance  with the  following  sentence,  interest
attributable  to  Capitalized   Lease   Obligations,   but  excluding   interest
attributable  to  Dollar-Denominated  Production  Payments and  amortization  of
deferred debt expense) during such period in respect of all  Indebtedness of the
Company and its Restricted  Subsidiaries (including (i) amortization of original
issue  discount or premium on any  Indebtedness  (other than with respect to the
Existing Notes and the  Securities),  (ii) the interest  portion of all deferred
payment  obligations,   calculated  in  accordance  with  GAAP,  and  (iii)  all
commissions,  discounts and other fees and charges owed with respect to bankers'
acceptance financings and currency and interest rate swap arrangements,  in each
case to the extent attributable to such period),  and (b) dividend  requirements
of the Company and its  Restricted  Subsidiaries  with respect to any  Preferred
Stock dividends  (whether in cash or otherwise  (except dividends paid solely in
shares of  Qualified  Stock))  paid  (other  than to the  Company  or any of its
Restricted Subsidiaries),  declared,  accrued or accumulated during such period,
divided by one minus the applicable  actual combined federal,  state,  local and
foreign  income tax rate of the Company  and its  Subsidiaries  (expressed  as a
decimal),  on a consolidated basis, for the four quarters immediately  preceding
the date of the  transaction  giving rise to the need to calculate  Consolidated
Interest  Expense,  in each case to the extent  attributable  to such period and
excluding items




                                                                               3


        eliminated  in  consolidation.  For  purposes  of this  definition,  (a)
interest  on a  Capitalized  Lease  Obligation  shall be  deemed to accrue at an
interest  rate  reasonably  determined by the Company to be the rate of interest
implicit in such  Capitalized  Lease  Obligation in accordance with GAAP and (b)
interest expense  attributable to any Indebtedness  represented by the guarantee
by the Company or a Restricted  Subsidiary  of the Company of an  obligation  of
another Person shall be deemed to be the interest  expense  attributable  to the
Indebtedness guaranteed.

        "Adjusted  Consolidated  Net Tangible  Assets" or "ACNTA" means (without
duplication),  as of the date of  determination,  (a) the sum of (i)  discounted
future net  revenue  from  proved oil and gas  reserves  of the  Company and its
Restricted  Subsidiaries calculated in accordance with SEC guidelines before any
state or federal income taxes, as estimated by independent  petroleum  engineers
in a  reserve  report  prepared  as of the end of the  Company's  most  recently
completed  fiscal year,  as increased by, as of the date of  determination,  the
discounted  future net revenue of (A)  estimated  proved oil and gas reserves of
the Company and its  Restricted  Subsidiaries  attributable  to any  acquisition
consummated  since the date of such year-end  reserve report,  and (B) estimated
proved oil and gas  reserves  of the  Company  and its  Restricted  Subsidiaries
attributable to extensions, discoveries and other additions and upward revisions
of estimates of proved oil and 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,  which,  in the  case  of
sub-clauses (A) and (B), would, in accordance with standard  industry  practice,
result  in such  increases  as  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 of (C)
estimated  proved  oil and  gas  reserves  of the  Company  and  its  Restricted
Subsidiaries  produced or disposed  of since the date of such  year-end  reserve
report and (D)  reductions  in the estimated oil and gas reserves of the Company
and its Restricted  Subsidiaries  since the date of such year-end reserve report
attributable  to downward  revisions of estimates of proved oil and 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
which,  in the  case of  sub-clauses  (C) and (D),  would,  in  accordance  with

of United States  Treasury  securities  for which such yields are given,  except
that if the  Make-Whole  Average Life of such  Securities is less than one year,

adjusted  to a  constant  maturity  of one year shall be used.  As used  herein,

        SECTION  2.01. FORM AND  DATING.  Provisions  relating  to the  Initial
Securities,  the Private Exchange Securities and the Exchange Securities are set
forth in the Rule  144A/Regulation  S Appendix  attached hereto (the "Appendix")
which is hereby  incorporated in and expressly made part of this Indenture.  The

substantially  in  the  form  of  Exhibit  1 to the  Appendix  which  is  hereby
incorporated  in and  expressly  made a part of  this  Indenture.  The  Exchange
Securities,  the Private  Exchange  Securities and the Trustee's  certificate of
authentication  shall be substantially in the form of Exhibit A, which is hereby
incorporated in and expressly made a part of this Indenture.  The Securities may
have notations,  legends or  endorsements  required by law, stock exchange rule,
agreements to which the Company is subject,  if any, or usage (PROVIDED that any
such notation,  legend or endorsement is in a form acceptable to the Company and
to the Trustee).  Each Security  shall be dated the date of its  authentication.
The terms of the  Securities set forth in the Appendix and Exhibit A are part of
the terms of this Indenture.



                                                                              23


        SECTION 2.02. EXECUTION AND AUTHENTICATION.  Two Officers shall sign the
Securities for the Company 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 signs the certificate of  authentication  on the Security.
The  signature  shall  be  conclusive   evidence  that  the  Security  has  been
authenticated under this Indenture.

                  On the Issue Date, the Trustee shall  authenticate and deliver
$600  million  of  Initial  Securities  and,  at any time and from  time to time
thereafter,  the Trustee shall  authenticate and deliver Securities for original
issue in an aggregate  principal  amount  specified in such order,  in each case
upon a written order of the Company  signed by two Officers or by an Officer and
either an Assistant  Treasurer or an  Assistant  Secretary 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, in
the case of an issuance of Additional  Securities pursuant to Section 2.13 after
the Issue Date,  shall certify that such issuance is in compliance  with Section
4.09.

                  The  Trustee may appoint an  authenticating  agent  reasonably
acceptable to the Company to authenticate the Securities.  Unless limited by the
terms of such appointment,  an 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.  An
authenticating  agent has the same  rights  with  respect to the  Company as any
Registrar, Paying Agent or agent for service of notices and demands.

        SECTION 2.03.  REGISTRAR AND PAYING AGENT. The Company shall maintain 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.  The
term "Paying Agent" includes any additional paying agent.

                  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 TIA. 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 any such  agent and shall  furnish  the
Trustee  with an  executed  counterpart  of any such  agency  agreement.  If the
Company fails to maintain a Registrar or Paying Agent,  the Trustee shall act as
such and shall be  entitled to  appropriate  compensation  therefor  pursuant to
Section  7.07.  The  Company  or any wholly  owned  Subsidiary  incorporated  or
organized  within  The  United  States  of  America  may  act as  Paying  Agent,
Registrar, co-registrar or transfer agent.



                                                                              24


                  The Company  initially  appoints the Trustee as Registrar  and
Paying Agent in connection with the Securities.

        SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST.  Prior to 11:00 a.m.,
New York time, each due date of the principal and interest on any Security,  the
Company  shall  deposit  with  the  Paying  Agent a sum  sufficient  to pay such
principal  and interest  when so becoming  due. The Company  shall  require each
Paying  Agent (other than the Trustee) to agree in writing that the Paying Agent
shall hold in trust for the  benefit of Holders or the Trustee all money held by
the Paying Agent for the payment of  principal of or interest 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 to pay all money held by it to
the Trustee and to account for any funds  disbursed  by the Paying  Agent.  Upon
complying  with this Section,  the Paying Agent shall have no further  liability
for the money delivered to the Trustee.

        SECTION 2.05.  HOLDER LISTS.  The Trustee shall preserve in as current a
form as is reasonably  practicable  the most recent list  available to it of the
names and addresses of Holders. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee, in writing at least five 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.

        SECTION 2.06.  TRANSFER AND EXCHANGE.  The Securities shall be issued in
registered form and shall be transferable  only upon the surrender of a Security
for registration of transfer. When a Security is presented to the Registrar or a
co-registrar with a request to register a transfer, the Registrar shall register
the transfer as  requested if the  requirements  of this  Indenture  and Section
8-401(a) of the Uniform  Commercial  Code are met. When Securities are presented
to the Registrar or a co-registrar  with a request to exchange them for an equal
principal amount of Securities of other denominations,  the Registrar shall make
the exchange as requested if the same requirements are met.

        SECTION  2.07.  REPLACEMENT  SECURITIES.  If  a  mutilated  Security  is
surrendered  to the  Registrar  or if the Holder of a Security  claims  that the
Security has been lost,  destroyed or wrongfully  taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform  Commercial  Code are met and the Holder  satisfies
any other reasonable  requirements of the Trustee. If required by the Trustee or
the Company,  such Holder  shall  furnish an indemnity  bond  sufficient  in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.


                                                                              25


                  Every replacement Security is an additional  obligation of the
Company.

        SECTION 2.08. OUTSTANDING SECURITIES. Securities outstanding at any time
are all Securities authenticated by the Trustee except for those canceled by it,
those delivered to it for cancelation and those described in this Section as not
outstanding.  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 2.07, it ceases
to be outstanding  unless the Trustee and the Company receive proof satisfactory
to them that the replaced Security is held by a bona fide purchaser.

                  If  the  Paying  Agent  segregates  and  holds  in  trust,  in
accordance  with this  Indenture,  on a redemption  date or maturity  date money
sufficient to pay all  principal and interest  payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing,  as the case
may be, then on and after that date such Securities (or portions  thereof) cease
to be outstanding and interest on them ceases to accrue.

        SECTION 2.09.  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  and
deliver them in exchange for temporary Securities.

        SECTION  2.10.  CANCELATION.   The  Company  at  any  time  may  deliver
Securities  to the Trustee for  cancelation.  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 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 or
cancelation and deliver a certificate of such  destruction to the Company unless
the Company directs the Trustee 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 for cancelation.

        SECTION 2.11.  DEFAULTED INTEREST.  If the Company defaults in a payment
of interest on the  Securities,  the Company shall pay defaulted  interest (plus
interest on such defaulted  interest to the extent lawful) 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 any
such special record date and payment date to the reasonable  satisfaction of the
Trustee and shall  promptly mail to each Holder a notice that states the special
record date, the payment date and the amount of defaulted interest to be paid.



                                                                              26


        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.

        SECTION 2.13.  ISSUANCE OF ADDITIONAL  SECURITIES.  The Company shall be
entitled,  subject to its compliance with Section  4.09(a),  to issue Additional
Securities  under this Indenture which shall have identical terms as the Initial
Securities  issued on the Issue  Date,  other  than with  respect to the date of
issuance and issue price. The Initial  Securities  issued on the Issue Date, any
Additional Securities and all Exchange Securities or Private Exchange Securities
issued in exchange  therefor shall be treated as a single class for all purposes
under this Indenture.

                  With respect to any Additional  Securities,  the Company shall
set  forth  in  a  resolution  of  the  Board  of  Directors  and  an  Officers'
Certificate,  a copy of each  which  shall  be  delivered  to the  Trustee,  the
following information:

                  1.  the  aggregate   principal   amount  of  such   Additional
        Securities to be authenticated and delivered pursuant to this Indenture;

                  2. the issue  price,  the issue  date and the CUSIP  number of
        such  Additional  Securities;  PROVIDED,  HOWEVER,  that  no  Additional
        Securities  may be issued at a price  that would  cause such  Additional
        Securities  to have  "original  issue  discount"  within the  meaning of
        Section 1273 of the Code; and

                  3.  whether  such  Additional  Securities  shall  be  Transfer
        Restricted  Securities  and issued in the form of Initial  Securities as
        set forth in the  Appendix to this  Indenture  or shall be issued in the
        form of Exchange Securities as set forth in Exhibit A.

         Additional  Securities  may be issued with the same CUSIP number as the
Securities  issued on the Issue  Date if, and only if,  the  Company  shall have
provided  the  Trustee  with  an  opinion  of  nationally   recognized  counsel,
reasonably  satisfactory  to the  Trustee,  to the effect  that such  Additional
Securities will be fungible with the Securities issued on the Issue Date for all
United States federal income tax purposes.


                                                                              27


                                 ARTICLE THREE

                                   REDEMPTION

        SECTION  3.01. NOTICE  TO  TRUSTEE.  If the  Company  elects  to redeem
Securities pursuant to the optional redemption  provisions of Paragraphs 5, 6 or
7 of the Securities, it shall furnish to the Trustee and the Registrar, at least
45 days but not more than 60 days before the redemption date (unless the Trustee
consents to a shorter period in writing), an Officers' Certificate setting forth
the redemption  date, the principal  amount of Securities to be redeemed and the
redemption  price,  including the detail of the  calculation  of the  Make-Whole
Price, if applicable.

        SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED.  If less than all
of the  Securities  are to be redeemed at any time, the Trustee shall select the
Securities to be redeemed pro rata, by lot or, if the  Securities  are listed on
any securities exchange, by any other method that the Trustee considers fair and
appropriate and that complies with the requirements of such exchange;  PROVIDED,
HOWEVER,  that no Securities  with a principal  amount of $1,000 or less will be
redeemed  in part.  The  Trustee  shall  make  the  selection  from  outstanding
Securities not  previously  called for redemption not less than 30 nor more than
60 days prior to the redemption date. Securities and portions of them it selects
shall be in amounts of $1,000 or whole  multiples 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 selected for redemption.

        SECTION 3.03.  NOTICE OF  REDEMPTION.  (a) At least 30 days but not more
than 60 days  before a  redemption  date,  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 aggregate  principal amount of Securities being
                  redeemed;

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

                         (5)  that  Securities  called  for  redemption  must be
                  surrendered  to the Paying  Agent at the address  specified in
                  such notice to collect the redemption price;

                         (6) that, unless the Company defaults in the payment of
                  the  redemption  price  or  accrued   interest,   interest  on
                  Securities called for redemption ceases to accrue on and after
                  the  redemption  date  and the  only  remaining  right  of the
                  Holders is to  receive  payment  of the  redemption  prices in
                  respect of the  Securities  upon surrender to the Paying Agent
                  of the Securities;


                                                                              28


                         (7) if any  Security  is being  redeemed  in part,  the
                  portion  of  the  principal  amount  of  such  Security  to be
                  redeemed and that,  after the redemption  date, upon surrender
                  of such  Security,  a new Security or  Securities in principal
                  amount equal to the  unredeemed  portion will be issued in the
                  name of the Holder thereof upon cancelation of the Security or
                  Securities being redeemed;

                         (8) the paragraph of the  Securities  pursuant to which
                  the Securities called for redemption are being redeemed; and

                         (9) the CUSIP number of the Securities.

                  (b) At the  Company's  request,  the  Trustee  shall  give the
notice of redemption  required in Section  3.03(a) in the Company's  name and at
the Company's expense; PROVIDED,  HOWEVER, that the Company shall deliver to the
Trustee,  at least 45 days prior to the  redemption  date  (unless  the  Trustee
consents  to a shorter  notice  period in  writing),  an  Officers'  Certificate
requesting  that the Trustee give such notice and setting forth the  information
to be stated in such notice as provided in Section 3.03(a).

        SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION. Once notice of redemption
is mailed in accordance  with Section  3.03,  Securities  called for  redemption
become due and payable on the  redemption  date at the  redemption  price.  Upon
surrender to the Paying Agent,  such Securities  shall be paid at the redemption
price,  plus accrued and unpaid  interest to the redemption date (subject to the
right of Holders of record on the relevant  record date to receive  interest due
on the related interest  payment 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 3.05. DEPOSIT OF REDEMPTION PRICE. Prior to 11:00 a.m., New York
time, the  redemption  date, 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) funds  available on the redemption  date sufficient to pay the redemption
price of, and accrued and unpaid  interest on, the  Securities to be redeemed on
that date.  The Paying Agent shall  promptly  return to the Company any money so
deposited which is not required for that purpose upon the written request of the
Company,  except  with  respect to monies  owed as  obligations  to the  Trustee
pursuant to Article Seven.

                  If any  Security  called for  redemption  shall not be so paid
upon  redemption  because  of the  failure  of the  Company  to comply  with the
preceding  paragraph,  interest  will  continue  to be  payable  on  the  unpaid
principal and premium,  if any,  including from the  redemption  date until such
principal  and  premium,  if any,  is paid,  and, to the extent  lawful,  on any
interest not paid on such unpaid principal, in each case at the rate provided in
the Securities and in Section 4.01 hereof.


                                                                              29


        SECTION 3.06.  SECURITIES REDEEMED IN PART. Upon surrender of a Security
that is to be redeemed in part,  the Company  shall issue and the Trustee  shall
authenticate for the Holder, at the expense of the Company, a new Security equal
in aggregate amount to the unredeemed portion of the Security surrendered.

        SECTION 3.07.  OPTIONAL REDEMPTION. Except as set forth in Sections 3.08
and 3.09 hereof,  the Company shall not have the option to redeem the Securities
prior to December 15, 2009.  The Securities may be redeemed at the option of the
Company, in whole or from time to time in part, at any time on or after December
15, 2009, at the redemption prices set forth below (expressed as a percentage of
the principal  amount of the  Securities to be redeemed),  together with accrued
and unpaid  interest on the  Securities so redeemed to the  redemption  date, if

2012 and thereafter..........................................     100.000%


                  Any redemption pursuant to this Section 3.07 shall be made, to
the extent applicable,  pursuant to the provisions of Sections 3.01 through 3.06
hereof.

        SECTION  3.08. EQUITY  OFFERING  REDEMPTION.  In the event the  Company
consummates  one or more Equity  Offerings on or prior to December 15, 2007, the
Company may redeem, in its sole discretion, up to 35% of the aggregate principal
amount of the Securities (which includes Additional Securities, if any) with all
or a portion of the aggregate net proceeds received by the Company from any such
Equity  Offering or Equity  Offerings at a  redemption  price of 106.375% of the
aggregate  principal  amount of the  Securities  so  redeemed,  plus accrued and
unpaid interest on the Securities so redeemed to the redemption date;  PROVIDED,
HOWEVER,  that (i) the date of any such  redemption  occurs  within  the  90-day
period after the Equity Offering in respect of which such redemption is made and
(ii) following  each such  redemption,  at least 65% of the aggregate  principal
amount of the Securities (which includes Additional Securities,  if any) remains
outstanding.

                  Any redemption pursuant to this Section 3.08 shall be made, to
the extent applicable,  pursuant to the provisions of Sections 3.01 through 3.06
hereof.

        SECTION 3.09. OPTIONAL REDEMPTION AT MAKE-WHOLE PRICE. At any time prior
to December 15, 2009 the Company  may, at its option,  redeem all or any portion
of the  Securities at the Make-Whole  Price plus accrued and unpaid  interest on
the Securities so redeemed to the date of redemption.



                                                                              30


                  Any redemption pursuant to this Section 3.09 shall be made, to
the extent applicable,  pursuant to the provisions of Sections 3.01 through 3.06
hereof.

                  The  Company  shall  pay  interest  (including   post-petition
interest in any proceeding under any Bankruptcy Law) on overdue  principal,  and
premium,  if any, at the rate borne by the Securities to the extent lawful;  and
it shall pay interest (including  post-petition interest in any proceeding under

files the same with the SEC,  shall  deliver  to  Holders,  copies of the annual

portions  of any of the  foregoing  as the  SEC  may by  rules  and  regulations
prescribe) that the Company is required to file with the SEC pursuant to Section
13 or 15(d) of the  Exchange  Act.  Notwithstanding  that the Company may not be
required to remain subject to the reporting  requirements of Section 13 or 15(d)

Subsidiary  Guarantor  shall also  comply  with the  provisions  of TIA  Section

such  Officer  may have  knowledge  and what  action  the  Company  is taking or
proposes to take with respect  thereto)  and that to the best of such  Officer's
knowledge,  after  reasonable  inquiry,  no event has  occurred  and  remains in
existence by reason of which  payments on account of the principal of,  premium,
if any, or interest,  if any, on the Securities are prohibited or, if such event
has  occurred,  a  description  of the event and what action the Company and the
Subsidiary  Guarantors are taking or propose to take with respect thereto.  Such
Officers'  Certificate  shall  comply  with TIA Section  314(a)(4).  The Company
hereby  represents that, as of the Issue Date, its fiscal year ends December 31,
and  hereby  covenants  that it shall  notify  the  Trustee  at least 30 days in
advance of any change in its fiscal year.


                                                                              31


                  (b)  So   long   as  not   contrary   to  the   then   current
recommendations of the American Institute of Certified Public  Accountants,  the
year-end  financial  statements  delivered  pursuant  to  Section  4.02 shall be
accompanied  by  a  written  statement  of  the  Company's   independent  public
accountants (which shall be a firm of established  national  reputation) that in
making the examination  necessary for certification of such financial statements
nothing  has come to their  attention  that would lead them to believe  that the
Company has violated any provisions of Sections 4.07,  4.09,  4.10, 4.11 or 4.15
of this Indenture (to the extent such provisions  relate to accounting  matters)
or, if any such  violation  has  occurred,  specifying  the nature and period of
existence thereof. Where such financial statements are not accompanied by such a
written  statement,  the Company  shall  furnish the Trustee  with an  Officers'
Certificate  stating  that any such written  statement  would be contrary to the
then  current  recommendations  of the American  Institute  of Certified  Public
Accountants.

                  (c) The Company and the Subsidiary Guarantors will, so long as
any of the Securities are outstanding, deliver to the Trustee forthwith upon any
Officer  becoming  aware of any  Default  or Event of  Default or default in the
performance of any covenant, agreement or condition contained in this Indenture,
an Officers'  Certificate  specifying  such Default or Event of Default and what
action the Company or any  Subsidiary  Guarantor  proposes to take with  respect
thereto.

        SECTION 4.04. MAINTENANCE OF OFFICE OR AGENCY. The Company will maintain
in the Borough of  Manhattan,  The City of New York,  an office or agency  where
Securities may be surrendered  for  registration  of transfer or exchange or for
presentation for payment and where notices and demands to or upon the Company in
respect of the  Securities  and this  Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in the
location,  of such office or agency.  If at any time the  Company  shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof,  such presentations,  surrenders,  notices and demands
may be made or served at the address of the Trustee set forth in Section  11.02.
If at any time the Company shall fail to maintain any required  office or agency
or shall fail to furnish the Trustee with the address thereof,  such surrenders,
presentations,  notices and demands may be made or served at the corporate trust
office of the Trustee.


                                                                              32


                  Subject to Section  2.03,  the  Company  may also from time to
time designate one or more other offices or agencies where the Securities may be
presented or surrendered  for any or all such purposes and may from time to time
rescind such  designations;  PROVIDED,  that no such  designation  or rescission
shall in any manner  relieve the Company of its obligation to maintain an office
or agency in the Borough of Manhattan,  The City of New York, for such purposes.
The  Company  will  give  prompt  written  notice  to the  Trustee  of any  such
designation  or  rescission  and of any change in the location of any such other
office or agency.

        SECTION 4.05.  CORPORATE  EXISTENCE.  The Company will do or cause to be
done all  things  necessary  to  preserve  and keep in full force and effect its
corporate  existence and the corporate,  partnership or other  existence of each
Subsidiary and all rights  (charter and statutory) and franchises of the Company
and the  Subsidiaries;  PROVIDED,  that the  Company  shall not be  required  to
preserve  the  corporate  existence  of any  Subsidiary,  or any  such  right or
franchise,  if the Company shall determine that the  preservation  thereof is no
longer desirable in the conduct of the business of the Company and that the loss
thereof is not disadvantageous in any material respect to the Holders.

        SECTION 4.06.  WAIVER OF STAY,  EXTENSION OR USURY LAWS. The Company and
each Subsidiary Guarantor covenants (to the extent that each may lawfully do so)
that it will not at any time insist  upon,  plead,  or in any manner  whatsoever
claim or take the benefit or advantage of, any stay, extension,  or usury law or
other law,  which  would  prohibit  or  forgive  the  Company or any  Subsidiary
Guarantor from paying all or any portion of the principal of,  premium,  if any,
or interest on the Securities as contemplated  herein,  wherever enacted, now or
at any time  hereafter  in  force,  or which may  affect  the  covenants  or the
performance  of this  Indenture;  and (to the extent that it may lawfully do so)
each of the Company and the Subsidiary  Guarantors  hereby  expressly waives all
benefit or  advantage of any such law,  and  covenants  that it will not hinder,
delay or impede the  execution of any power herein  granted to the Trustee,  but
will suffer and permit the  execution  of every such power as though no such law
had been enacted.

        SECTION 4.07.  PAYMENT OF TAXES AND OTHER CLAIMS.  The Company shall pay
or  discharge  or cause to be paid or  discharged,  before the same shall become
delinquent,  (a) all  taxes,  assessments  and  governmental  charges  levied or
imposed  upon the  Company  or any  Subsidiary  or upon the  income,  profits or
property of the Company or any  Subsidiary  and (b) all lawful claims for labor,
materials  and supplies  which,  if unpaid,  might by law become a Lien upon the
property of the Company or any Subsidiary;  PROVIDED,  HOWEVER, that the Company
shall not be required to pay or discharge or cause to be paid or discharged  any
such tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.


                                                                              33


        SECTION 4.08.  MAINTENANCE OF PROPERTIES AND INSURANCE.  (a) The Company
shall cause all  properties  used or held for use in the conduct of its business
or the business of any Subsidiary to be maintained  and kept in good  condition,
repair and working order (ordinary wear and tear excepted) and supplied with all
necessary equipment and shall cause to be made all necessary repairs,  renewals,
replacements,  betterments and improvements  thereof,  all as in the judgment of
the Company  may be  necessary  so that the  business  carried on in  connection
therewith may be properly and advantageously  conducted at all times;  PROVIDED,
HOWEVER,   that  nothing  in  this  Section   shall  prevent  the  Company  from
discontinuing the operation or maintenance of any such property, or disposing of
it, if such  discontinuance  or disposal  is, in the  judgment  of the  Company,
desirable in the conduct of its business and not disadvantageous in any material
respect to the Holders.

                  (b) The Company  shall  provide or cause to be  provided,  for
itself  and  each  of  its  Subsidiaries,   insurance   (including   appropriate
self-insurance)  against  loss or damage of the kinds that,  in the  reasonable,
good faith opinion of the Company,  are adequate and appropriate for the conduct
of the business of the Company and such  Subsidiaries in a prudent manner,  with
reputable  insurers or with the  government of the United States or an agency or
instrumentality  thereof,  in such amounts,  with such deductibles,  and by such
methods as shall be  customary,  in the  reasonable,  good faith  opinion of the
Company, for corporations similarly situated in the industry.

        SECTION 4.09. LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS.

                  (a) The  Company  will  not,  and will not  permit  any of its
Restricted  Subsidiaries,  directly  or  indirectly,  to issue,  incur,  assume,
guarantee,  become  liable,  contingently  or  otherwise,  with  respect  to  or
otherwise  become  responsible  for the payment of  (collectively,  "incur") any
Indebtedness;  PROVIDED,  HOWEVER,  that if no Default or Event of Default shall
have  occurred  and  be  continuing  at  the  time  or as a  consequence  of the
incurrence of such Indebtedness,  the Company or its Restricted Subsidiaries may
incur  Indebtedness  if,  on a pro  forma  basis,  after  giving  effect to such
incurrence  and  the  application  of  the  proceeds  therefrom,  either  of the
following tests shall have been satisfied:  (i) the Adjusted Consolidated EBITDA
Coverage  Ratio  would  have  been  at  least  2.25 to  1.0;  or  (ii)  Adjusted
Consolidated   Net  Tangible  Assets  would  have  been  greater  than  200%  of
Indebtedness of the Company and its Restricted Subsidiaries.

                  (b) Notwithstanding  the foregoing,  if no Default or Event of
Default shall have occurred and be continuing at the time or as a consequence of
the incurrence of such Indebtedness, the Company and its Restricted Subsidiaries
may incur Permitted  Indebtedness.  For purposes of determining  compliance with
this Section 4.09:

                  (i) in the event that an item of proposed  Indebtedness  meets
        the  criteria  of  more  than  one  of  the   categories   of  Permitted
        Indebtedness  as of the date of incurrence  thereof or is entitled to be
        incurred  pursuant  to  Section  4.09(a)  as of the  date of  incurrence
        thereof,  the Company shall, in its sole discretion,  classify (or later
        classify  in whole or in part,  in its  sole  discretion)  such  item of
        Indebtedness in any manner that complies with this Section 4.09, and

                                                                              34


                  (ii)  for  purposes  of   determining   compliance   with  any
        dollar-denominated   restriction  on  the  incurrence  of   Indebtedness
        denominated  in a  foreign  currency,  the  dollar-equivalent  principal
        amount  of  such   Indebtedness   incurred  pursuant  thereto  shall  be
        calculated based on the relevant currency.

Accrual of interest or dividends, the accretion of accreted value or liquidation
preference  and the payment of interest or dividends  in the form of  additional
Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes
of this Section 4.09.

                  (c) Any  Indebtedness  of a Person  existing  at the time such
Person  becomes a  Restricted  Subsidiary  (whether  by  merger,  consolidation,
acquisition  or  otherwise)  shall be deemed to be incurred  by such  Restricted
Subsidiary at the time it becomes a Restricted Subsidiary.

        SECTION 4.10.  LIMITATION ON RESTRICTED  PAYMENTS.  (a) The Company will
not,  and will not permit any of its  Restricted  Subsidiaries  to,  directly or
indirectly, make any Restricted Payment, unless:

                  (i) no Default or Event of Default  shall have occurred and be
        continuing  at the time of or  immediately  after giving  effect to such
        Restricted Payment;

                  (ii) at the time of and  immediately  after  giving  effect to
        such  Restricted  Payment,  the Company  would be able to incur at least
        $1.00 of additional  Indebtedness  (other than  Permitted  Indebtedness)
        pursuant to Section 4.09(a); and

                  (iii)  immediately  after  giving  effect  to such  Restricted
        Payment, the aggregate of all Restricted Payments declared or made after
        the  Reference  Date  does  not  exceed  the  sum  of  (A)  50%  of  the
        Consolidated  Net Income of the Company and its Restricted  Subsidiaries
        (or in the event such Consolidated Net Income shall be a deficit,  minus
        100% of such  deficit)  during the  period  (treated  as one  accounting
        period)  subsequent to the Reference  Date and ending on the last day of
        the fiscal  quarter  immediately  preceding the date of such  Restricted
        Payment; (B) the aggregate Net Cash Proceeds,  and the fair market value
        of  property  other  than  cash  (as  determined  in good  faith  by the
        Company's  Board of Directors  and  evidenced  by a  resolution  of such
        Board), received by the Company during such period from any Person other
        than a Subsidiary  of the Company as a result of the issuance or sale of
        Capital  Stock of the  Company  (other than any  Disqualified  Stock and
        other than  Preferred  Shares issued in the Preferred  Stock  Offering),
        other  than  in  connection  with  the  conversion  of  Indebtedness  or
        Disqualified  Stock;  (C) the aggregate Net Cash Proceeds,  and the fair
        market value of property other than cash (as determined in good faith by


                                                                              35


        the  Company's  Board of Directors and evidenced by a resolution of such
        Board), received by the Company during such period from any Person other
        than a Subsidiary  of the Company as a result of the issuance or sale of
        any  Indebtedness or  Disqualified  Stock to the extent that at the time
        the  determination is made such  Indebtedness or Disqualified  Stock, as
        the case may be, has been  converted into or exchanged for Capital Stock
        of the Company (other than Disqualified  Stock);  and (D)(i) in case any
        Unrestricted  Subsidiary has been redesignated a Restricted  Subsidiary,
        an amount  equal to the  lesser  of (x) the book  value  (determined  in
        accordance with GAAP) at the date of such redesignation of the aggregate
        Investments made by the Company and its Restricted  Subsidiaries in such
        Unrestricted   Subsidiary   and  (y)  the  fair  market  value  of  such
        Investments  in  such  Unrestricted  Subsidiary  at  the  time  of  such
        redesignation,  as determined  in good faith by the  Company's  Board of
        Directors,   including  a  majority  of  the   Company's   Disinterested
        Directors,  whose  determination  shall be conclusive and evidenced by a
        resolution of such Board; or (ii) in case any Restricted  Subsidiary has
        been redesignated an Unrestricted  Subsidiary,  minus the greater of (x)
        the book  value  (determined  in  accordance  with  GAAP) at the date of
        redesignation  of the aggregate  Investments made by the Company and its
        Restricted  Subsidiaries in such Restricted  Subsidiary and (y) the fair
        market value of such  Investments in such  Restricted  Subsidiary at the
        time of such redesignation, as determined in good faith by the Company's
        Board of Directors,  including a majority of the Company's Disinterested
        Directors,  whose  determination  shall be conclusive and evidenced by a
        resolution of such Board.

          (b)  Notwithstanding  the foregoing,  the above  limitations  will not
prevent  (i) the  payment  of any  dividend  within  60 days  after  the date of
declaration  thereof,  if at such date of declaration such payment complied with
the provisions hereof; (ii) the purchase, redemption,  acquisition or retirement
of any shares of Capital Stock of the Company in exchange for, or out of the net
proceeds  of the  substantially  concurrent  sale  (other  than to a  Restricted
Subsidiary  of the  Company)  of,  other  shares of Capital  Stock  (other  than
Disqualified  Stock) of the Company;  (iii) any  dividend or other  distribution
payable  from a  Restricted  Subsidiary  to the Company or any other  Restricted
Subsidiary;   (iv)  regularly   quarterly  dividends  on  the  6.00%  Cumulative
Convertible Preferred Stock, the 5.00% Cumulative Convertible Preferred Stock or
the 4.125% Cumulative  Convertible Preferred Stock of the Company outstanding on
the Issue Date, PROVIDED that no Default or Event of Default shall have occurred
and be continuing at the time of or immediately  after giving effect to any such
Restricted  Payment;  and  (v)  other  Restricted  Payments  not  in  excess  of
$25,000,000 in the aggregate  since the Issue Date,  PROVIDED that no Default or
Event  of  Default  shall  have  occurred  and be  continuing  at the time of or
immediately after giving effect to any such Restricted  Payment.  Any Restricted
Payment  described  in the  preceding  clause (iii) shall be  excludable  in the
calculation of the amount of Restricted  Payments,  and any  Restricted  payment
described in any other clause shall be included in the calculation.



                                                                              36


        SECTION 4.11.  LIMITATION  ON SALE OF ASSETS.  (a) The Company will not,
and will not permit any Restricted Subsidiary to, make any Asset Sale unless:

                  (i) the Company (or its Restricted  Subsidiaries,  as the case
        may  be)  receives  consideration  at the  time of  such  sale or  other
        disposition  at  least  equal  to the  fair  market  value  thereof  (as
        determined  in good  faith  by the  Company's  Board  of  Directors  and
        evidenced  by a  resolution  of such Board,  including a majority of the
        Company's  Disinterested  Directors,  in the case of any Asset  Sales or
        series of related Asset Sales having a fair market value of  $20,000,000
        or greater);

                  (ii) (A) the consideration consists of cash, cash equivalents,
        Permitted  Financial  Investments  or  property,  equipment,   leasehold
        interests or other  assets used in the Oil and Gas Business  ("Permitted
        Consideration")  or (B) the portion of the  consideration  that does not
        constitute   Permitted   Consideration,    together   with   all   other
        consideration  received  for Asset  Sales since the Issue Date that does
        not constitute  Permitted  Consideration,  has a fair market value of no
        more than 10% of ACNTA; and

                  (iii) the Net Available  Proceeds  received by the Company (or
        its  Restricted  Subsidiaries,  as the case may be) from such Asset Sale
        are applied in accordance with paragraphs (b) or (c) hereof.

            (b) The Company  may apply such Net  Available  Proceeds  within 365
days after  receipt of Net Available  Proceeds from any Asset Sale,  to: (i) the
repayment of Indebtedness of the Company under Credit Facilities or other Senior
Indebtedness,  including  any  mandatory  redemption  or  repurchase or optional
redemption of the Existing Notes or the  Securities;  (ii) make an Investment in
assets  used in the Oil and Gas  Business;  or (iii)  develop  by  drilling  the
Company's oil and gas reserves.

            (c) If, upon completion of the 365-day period referred to above, any
portion  of the Net  Available  Proceeds  of any Asset  Sale shall not have been
applied  by the  Company  as  described  in  clauses  (i),  (ii) or (iii) of the
immediately  preceding  paragraph and such  remaining  Net  Available  Proceeds,
together  with any  remaining  net cash proceeds from any prior Asset Sale (such
aggregate constituting "Excess Proceeds"),  exceed $15,000,000, then the Company
will be  obligated to make an offer (the "Net  Proceeds  Offer") to purchase the
Securities and any other Senior  Indebtedness  in respect of which such an offer
to  purchase is required to be made  concurrently  with the Net  Proceeds  Offer
having an aggregate principal amount equal to the Excess Proceeds (such purchase
to be made on a pro rata basis if the amount  available  for such  repurchase is
less than the principal  amount of the Securities and other Senior  Indebtedness
tendered  in  such  Net  Proceeds  Offer)  at a  purchase  price  of 100% of the
principal  amount thereof plus accrued and unpaid interest on the Securities and
other Senior  Indebtedness  so repurchased  to the date of repurchase.  Upon the
completion  of the Net Proceeds  Offer,  the amount of Excess  Proceeds  will be
reset to zero.



                                                                              37


            (d) The Company shall commence a Net Proceeds Offer by preparing and
mailing a notice to the  Trustee,  the Paying  Agent and each  Holder as of such
record date as the Company shall establish (upon written notice to the Trustee).
Notice of a Net Proceeds Offer to purchase the Securities will be made on behalf
of the  Company not less than 25  Business  Days nor more than 60 Business  Days
before the payment date of the Net  Proceeds  Offer (the "Net  Proceeds  Payment
Date"),  and shall set forth the Net Proceeds  Offer Amount and the Net Proceeds
Payment  Date and  refer to and  summarize  the  material  points  contained  in
Sections 4.11(d) and (e) hereof.  Securities tendered to the Company pursuant to
a Net  Proceeds  Offer  will  cease to accrue  interest  after the Net  Proceeds
Payment  Date.  For  purposes of this  covenant,  the term "Net  Proceeds  Offer
Amount" means the principal of outstanding  Securities in an aggregate principal
amount equal to any remaining Net Available Proceeds (rounded to the next lowest
$1,000).  If the Net Proceeds  Payment  Date is on or after an interest  payment
record  date and on or before the related  interest  payment  date,  any accrued
interest  payable on such  interest  payment  date will be paid to the Person in
whose name a Security  is  registered  at the close of  business  on such record
date,  and no  additional  interest  will  be  payable  to  Holders  who  tender
Securities pursuant to the Net Proceeds Offer.

            (e) On the Net Proceeds  Payment  Date,  the Company will (i) accept
for payment  Securities  and any other Senior  Indebtedness  in respect of which
such an offer to  purchase  is  required  to be made  concurrently  with the Net
Proceeds  Offer or portions  thereof  pursuant to the Net  Proceeds  Offer in an
aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser
amount as has been  tendered,  (ii)  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 purchase  price of all  Securities  and such other
Senior  Indebtedness or portions  thereof so tendered in an aggregate  principal
amount equal to the Net Proceeds Offer Amount or such lesser  amount,  including
any  accrued  and  unpaid  interest  thereon,  and (iii)  deliver or cause to be
delivered  to the Trustee,  Securities  so accepted  together  with an Officers'
Certificate  stating the Securities or portions thereof tendered to the Company.
If  the  aggregate   principal  amount  of  Securities  and  such  other  Senior
Indebtedness  tendered  exceeds the Net Proceeds Offer Amount,  the Trustee will
select the Securities and other Senior Indebtedness to be purchased (in integral
multiples  of  $1,000)  on a pro rata  basis  based on the  principal  amount of
Securities and other Senior Indebtedness so tendered and notify the Company, the
Registrar  and the Paying  Agent.  The Paying  Agent,  upon  instruction  of the
Company,  will  promptly  mail or deliver to Holders of  Securities  so accepted
payment in an amount  equal to the  purchase  price  (representing  those  funds
received pursuant to clause (ii) of this Section 4.11(e)),  and the Company will
execute and the Trustee will promptly  authenticate  and mail or make  available
for  delivery  to  Holders  a new  Security  equal in  principal  amount  to any
unpurchased portion of the Security surrendered.  Any Securities not so accepted
will be promptly  mailed or delivered to the Holder thereof by the Company,  or,
if the Company so directs the  Trustee,  by the Trustee on behalf of the Company
at the Company's expense.  The Company will publicly announce the results of the
Net Proceeds Offer on or as soon as practicable  after the Net Proceeds  Payment
Date.  For  purposes of this  Section  4.11,  the Trustee will act as the Paying
Agent.

                                                                              38


            (f) The Company  will comply with Section 14 of the Exchange Act and
the  provisions  of  Regulation  14E and any other  tender offer rules under the
Exchange  Act and any  other  federal  and  state  securities  laws,  rules  and
regulations which may then be applicable to any Net Proceeds Offer.

            (g) During the period between any Asset Sale and the  application of
the Net Available Proceeds  therefrom in accordance with this covenant,  all Net
Available  Proceeds  shall be  maintained  in a segregated  account and shall be
invested in Permitted Financial Investments.

            (h) Notwithstanding the foregoing, the Company will not and will not
permit any Restricted Subsidiary to, directly or indirectly, make any Asset Sale
of any of the Capital  Stock of a Restricted  Subsidiary  except  pursuant to an
Asset Sale of all of the Capital Stock of such Restricted Subsidiary.

        SECTION 4.12.  LIMITATION ON LIENS  SECURING  INDEBTEDNESS.  The Company
will not, and will not permit any of its  Restricted  Subsidiaries  to,  create,
incur, assume or suffer to exist any Liens (other than Permitted Liens) upon any
of their  respective  properties  securing (i) any  Indebtedness of the Company,
unless the Securities are equally and ratably  secured or (ii) any  Indebtedness
of any  Restricted  Subsidiary,  unless the  Guarantees  are equally and ratably
secured;  PROVIDED,  that if such Indebtedness is expressly  subordinated to the
Securities  or the  Guarantees,  the Lien  securing  such  Indebtedness  will be
subordinated  and junior to any Lien securing the Securities or the  Guarantees,
with the same relative priority as such Subordinated Indebtedness of the Company
or Subordinated  Indebtedness of a Restricted  Subsidiary will have with respect
to the Securities or the Guarantees, as the case may be.

        SECTION 4.13.  LIMITATION ON  SALE/LEASEBACK  TRANSACTIONS.  The Company
will not, and will not permit any of its Restricted  Subsidiaries to, enter into
any  Sale/Leaseback  Transaction  with any Person (other than the Company or any
other  Restricted   Subsidiary)  unless  (i)  the  Company  or  such  Restricted
Subsidiary,  as the  case  may be,  would  be able to  incur  Indebtedness  in a
principal  amount equal to the  Attributable  Indebtedness  with respect to such
Sale/Leaseback  Transaction in accordance  with Section 4.09 or (ii) the Company
or  such  Restricted  Subsidiary  receives  proceeds  from  such  Sale/Leaseback
Transaction  at least equal to the fair market value  thereof (as  determined in
good faith by the Company's  Board of  Directors,  whose  determination  in good
faith,  evidenced by a resolution  of such Board shall be  conclusive)  and such
proceeds are applied in the same manner and to the same extent as Net  Available
Proceeds and Excess Proceeds from an Asset Sale.

        SECTION 4.14. LIMITATION ON PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.
The Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly,  create or otherwise  cause or suffer to exist or become
effective any consensual encumbrance or consensual restriction on the ability of
any Restricted  Subsidiary of the Company to (i) pay dividends or make any other
distributions  on its Capital  Stock to the Company or a Restricted  Subsidiary,
(ii) pay any Indebtedness owed to the Company or a Restricted  Subsidiary of the
Company;  (iii) make loans or advances to the Company or a Restricted Subsidiary

                                                                              39


of the Company;  or (iv) transfer any of its properties or assets to the Company
or a  Restricted  Subsidiary  of the Company  (each,  a "Payment  Restriction"),
except for (a) encumbrances or restrictions under Credit  Facilities;  PROVIDED,
that any Payment  Restrictions  thereunder  (other  than,  with  respect to (iv)
above,  customary  restrictions  in security  agreements or other loan documents
thereunder securing or governing Indebtedness of a Restricted Subsidiary) may be
imposed  only  upon  the  acceleration  of  the  maturity  of  the  Indebtedness
thereunder;  (b) consensual encumbrances or consensual restrictions binding upon
any  Person  at the time such  Person  becomes a  Restricted  Subsidiary  of the
Company  (unless  the  agreement   creating  such  consensual   encumbrances  or
consensual restrictions was entered into in connection with, or in contemplation
of, such entity becoming a Restricted  Subsidiary);  (c) consensual encumbrances
or consensual  restrictions  under any agreement that refinances or replaces any
agreement  described in clauses (a) and (b) above,  PROVIDED  that the terms and
conditions of any such  restrictions  are in the aggregate no less  favorable to
the holders of the  Securities  than those under the  agreement so refinanced or
replaced; and (d) customary non-assignment  provisions in leases, purchase money
financings and any encumbrance or restriction due to applicable law.

        SECTION 4.15.  LIMITATION ON TRANSACTIONS  WITH AFFILIATES.  The Company
will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly,  enter into any  transaction or series of  transactions  (including,
without  limitation,  the sale, purchase or lease of any assets or properties or
the  rendering  of any  services)  with any  Affiliate or  beneficial  owner (as
defined in Rules 13d-3 and 13d-5 under the  Exchange  Act) of 10% or more of the
Company's common stock (other than with a Restricted  Subsidiary of the Company)
(an "Affiliate Transaction"), on terms that are less favorable to the Company or
such  Restricted  Subsidiary,  as the case may be, than would be  available in a
comparable  transaction with an unrelated Person. In addition,  the Company will
not, and will not permit any Restricted Subsidiary of the Company to, enter into
an Affiliate Transaction, or any series of related Affiliate Transactions having
a value of (a) more than $5,000,000  unless a majority of the Board of Directors
of the Company (including a majority of the Company's  Disinterested  Directors)
determines in good faith, as evidenced by a resolution of such Board,  that such
Affiliate Transaction or series of related Affiliate Transactions is fair to the
Company;  or (b) more than  $25,000,000,  unless the Company  receives a written
opinion from a nationally  recognized  investment banking firm with total assets
in excess of  $1,000,000,000  that such transaction or series of transactions is
fair to the Company from a financial point of view.

        SECTION 4.16.  CHANGE OF CONTROL.  (a)  Following the  occurrence of any
Change of  Control,  the Company  shall  offer (a "Change of Control  Offer") to
purchase all  outstanding  Securities  at a purchase  price equal to 101% of the
aggregate  outstanding  principal  amount of the  Securities,  plus  accrued and
unpaid  interest on the  Securities  so purchased  to the date of purchase.  The
Change of Control  Offer shall be deemed to have  commenced  upon mailing of the
notice  described  in the next  succeeding  paragraph  and  shall  terminate  20
Business  Days  after  its  commencement,  unless a longer  offering  period  is
required by law.  Promptly after the  termination of the Change of Control Offer


                                                                              40


(the "Change of Control Payment  Date"),  the Company shall purchase and mail or
deliver payment for all Securities tendered in response to the Change of Control
Offer. 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
interest  payable on such  interest  payment  date will be paid to the Person in
whose name a Security  is  registered  at the close of  business  on such record
date,  and no  additional  interest  will  be  payable  to  Holders  who  tender
Securities pursuant to the Change of Control Offer.

          (b) Within 15 days  after any Change of  Control,  the  Company  (with
notice to the Trustee  and the Paying  Agent),  or the Trustee at the  Company's
request and expense,  will mail or cause to be mailed to all Holders on the date
of the  Change of  Control a notice  prepared  by the  Company  (the  "Change of
Control Notice") of the occurrence of such Change of Control and of the Holders'
rights  arising as a result  thereof.  The Change of Control Notice will contain
all  instructions  and  materials  necessary  to enable  Holders to tender their
Securities to the Company.  The Change of Control Notice, which shall govern the
terms of the  Change of  Control  Offer,  shall  state:  (1) that the  Change of
Control  Offer is being made  pursuant to this  Section  4.16;  (2) the purchase
price and the Change of Control Payment Date; (3) that any Security not tendered
will  continue to accrue  interest  at the stated  rate;  (4) that any  Security
accepted  for  payment  pursuant  to the Change of Control  Offer shall cease to
accrue interest on the Change of Control Payment Date; (5) that Holders electing
to have a Security  purchased  pursuant  to any Change of Control  Offer will be
required to surrender the Security,  with the form entitled "Option of Holder to
Elect  Purchase" on the reverse of the  Security  completed,  to the Company,  a
depositary,  if  appointed  by the  Company,  or a Paying  Agent at the  address
specified in the notice prior to termination of the Change of Control Offer; (6)
that  Holders  will be  entitled  to withdraw  their  election  if the  Company,
depositary or Paying  Agent,  as the case may be,  receives,  not later than the
expiration  of the  Change of Control  Offer,  or such  longer  period as may be
required by law, a telegram,  telex,  facsimile  transmission  or letter setting
forth the name of the Holder,  the  principal  amount of the Security the Holder
delivered  for  purchase  and a statement  that such Holder is  withdrawing  its
election to have the Security  purchased;  and (7) that Holders whose Securities
are purchased only in part will be issued  Securities  equal in principal amount
to the unpurchased portion of the Securities surrendered.

          (c) On the Change of Control  Payment Date, the Company shall,  to the
extent  permitted  by  applicable  law,  (i) accept for  payment  Securities  or
portions thereof tendered pursuant to the Change of Control Notice,  (ii) if the
Company  appoints a depositary or Paying Agent,  deposit with such depositary or
Paying Agent money  sufficient  to pay the purchase  price of all  Securities or
portions  thereof so tendered  and (iii)  deliver to the Trustee  Securities  so
accepted  together  with an  Officers'  Certificate  stating the  Securities  or
portions  thereof  tendered to the Company.  The depositary,  the Company or the
Paying  Agent,  as the  case  may be,  shall  promptly  mail to the  Holders  of
Securities  so  accepted  payment  in an  amount  equal  to the  purchase  price
(representing  those funds  received  pursuant  to clause  (ii) of this  Section
4.16(c)),  and the Trustee  shall  promptly  authenticate  and mail to each such


                                                                              41


Holder a new Security equal in principal  amount to any  unpurchased  portion of
the Security  surrendered;  PROVIDED  that each such new  Security  will be in a
principal  amount of $1,000 or an integral  multiple  thereof.  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.  For  purposes  of this

regulations which may then be applicable to any offer by the Company to purchase
the Securities at the option of the Holders upon a Change of Control.

        such  consolidation or into which the Company is merged or that acquires
        by sale, conveyance, transfer or other disposition, or which leases, all
        or  substantially  all of the  assets of the  Company  is a  corporation
        organized  and existing  under the laws of the United States of America,
        any state thereof or the District of Columbia, or Canada or any province
        thereof, and expressly assumes, by supplemental  indenture,  the due and
        punctual payment of the principal of, premium,  if any, and interest on,
        all the  Securities  and the  performance  of every other  covenant  and
        obligation of the Company under this Indenture;

        pro forma basis,  the Company (or the  surviving or  transferee  entity)
        would be able to incur $1.00 of additional  Indebtedness  under the test
        described in Section 4.09(a) (other than Permitted Indebtedness).

                  In   connection   with  any   consolidation,   merger,   sale,
conveyance,  lease,  transfer or other disposition  contemplated by this Section

proposed  transaction an Officers'  Certificate  to the foregoing  effect and an
Opinion of Counsel stating that the proposed  transaction and such  supplemental
indenture comply with this Indenture.



                                                                              42

predecessor  corporation  will  be  relieved  of  all  further  obligations  and
covenants under this Indenture and the Securities.


                                  ARTICLE SIX

                              DEFAULTS AND REMEDIES

        SECTION  6.01. EVENTS OF DEFAULT.  An "Event of Default"  occurs  upon:

        and payable at  maturity,  upon  repurchase  pursuant to Section 4.11 or
        4.16, upon acceleration or otherwise;

                  (2) default by the Company or any Subsidiary  Guarantor in the

        any  Subsidiary   Guarantor  or  any  other  Subsidiary  (other  than  a
        Non-Recourse  Subsidiary or an  Unrestricted  Subsidiary)  if either (A)
        such  default  results in the  acceleration  of the maturity of any such
        Indebtedness   having  a  principal   amount  of   $10,000,000  or  more
        individually  or, taken together with the principal  amount of any other
        such Indebtedness the maturity of which has been so accelerated,  in the
        aggregate,  or (B) such default results from the failure to pay when due
        principal of,  premium,  if any, or interest on, any such  Indebtedness,
        after  giving  effect  to  any  applicable   grace  period  (a  "Payment
        Default"), having a principal amount of $10,000,000 or more individually
        or, taken together with the principal  amount of any other  Indebtedness
        under which there has been a Payment Default, in the aggregate;

                                                                              43


                  (5) default in the  performance,  or breach of, the  covenants
        set forth in Section 4.10 and Article  Five, or in the  performance,  or
        breach  of,  any other  covenant  or  agreement  of the  Company  or any
        Subsidiary  Guarantor  in this  Indenture  and  failure  to remedy  such
        default within a period of 45 days after written notice thereof from the
        Trustee  or Holders of 25% of the  principal  amount of the  outstanding
        Securities;

                  (6) the  entry by a court of one or more  judgments  or orders
        for the payment of money against the Company,  any Subsidiary  Guarantor

        Unrestricted  Subsidiary,  PROVIDED  that  neither  the  Company nor any
        Restricted  Subsidiary is -------- liable,  directly or indirectly,  for
        such judgment or order) in an aggregate  amount in excess of $10,000,000
        (net of applicable  insurance coverage by a third party insurer which is
        acknowledged  in writing  by such  insurer)  that has not been  vacated,
        discharged,  satisfied or stayed  pending appeal within 60 days from the
        entry thereof;

                  (7) a Guarantee by a Subsidiary Guarantor shall cease to be in
        full force and effect (other than a release of a Guarantee in accordance
        with Section 10.04) or any Subsidiary  Guarantor shall deny or disaffirm
        its obligations with respect thereto;

                  (8) the Company or any  Subsidiary  (other than a Non-Recourse
        Subsidiary  or an  Unrestricted  Subsidiary)  pursuant  to or within the
        meaning of any Bankruptcy Law:

                         (A) commences a voluntary case or proceeding,

                         (B)  consents  to the  entry  of an  order  for  relief

                         (C) consents to the appointment of a Custodian of it or

                  creditors, or

                         (E) admits in writing  that it  generally  is unable to
                  pay its debts as the same become due; or

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

                         (A)  is  for  relief  (with  respect  to  the  petition
                  commencing  such case)  against the Company or any  Subsidiary
                  (other  than  a  Non-Recourse  Subsidiary  or an  Unrestricted
                  Subsidiary) in an involuntary case or proceeding,

                                                                              44

                  The term  "Bankruptcy  Law" means Title 11,  U.S.  Code or any
similar  federal or state law for the relief of  debtors.  The term  "Custodian"
means any receiver, trustee, assignee,  liquidator or similar official under any
Bankruptcy Law.

        SECTION 6.02. ACCELERATION.  If an Event of Default (other than an Event
of Default  specified  in clauses (8) or (9)) under  Section  6.01 occurs and is
continuing,  then and in every such case the  Trustee or the Holders of not less
than 25% of the principal  amount of the outstanding  Securities may declare the
unpaid principal of and premium, if any, or the Change of Control purchase price
if the Event of Default  includes  failure to pay the Change of Control purchase
price,  and accrued and unpaid interest on, all the Securities then  outstanding
to be due and  payable,  by a  notice  in  writing  to the  Company  (and to the
Trustee,  if given by Holders),  and upon any such  declaration  such principal,
premium,  if any, and accrued and unpaid  interest shall become  immediately due
and  payable,  notwithstanding  anything  contained  in  this  Indenture  or the
Securities to the contrary.  If an Event of Default  specified in clauses 8 or 9
above  occurs,  all unpaid  principal  of, and premium,  if any, and accrued and
unpaid interest on, the Securities then outstanding will become due and payable,
without any declaration or other act on the part of the Trustee or any Holder.

                  The  Holders  of a  majority  of the  principal  amount of the
outstanding  Securities,  by  written  notice  to the  Company,  the  Subsidiary
Guarantors and the Trustee,  may rescind and annul a declaration of acceleration
and its consequences if (1) the Company or any Subsidiary  Guarantor has paid or
deposited with such Trustee a sum sufficient to pay (A) all overdue installments
of interest on all the Securities, (B) the principal of, and premium, if any, on
any  Securities  that have  become due  otherwise  than by such  declaration  of
acceleration and interest  thereon at the rate or rates  prescribed  therefor in
the  Securities,  (C) to the extent  that  payment of such  interest  is lawful,
interest on the defaulted  interest at the rate or rates prescribed  therefor in
the Securities, and (D) all money paid or advanced by the Trustee thereunder and
the  reasonable  compensation,  expenses,  disbursements  and  advances  of  the
Trustee,  its agents and  counsel;  (2) all  Events of  Default,  other than the
non-payment  of the principal of any  Securities  that have become due solely by
such declaration of acceleration,  have been cured or waived as provided in this
Indenture; and (3) the rescission would not conflict with any judgment or decree
of a court  of  competent  jurisdiction.  No such  rescission  will  affect  any
subsequent Event of Default or impair any right consequent thereon.

                                                                              45


        SECTION  6.03. OTHER  REMEDIES.  If an  Event of  Default  occurs and is
continuing,  the Trustee may, but is not obligated to,  pursue,  in its own name
and as trustee of an express trust, any available remedy by proceeding at law or
in equity to collect the payment of principal or interest on the  Securities  or
to enforce the performance of any provision of the Securities or this Indenture.
If an Event of Default specified under clauses (8) or (9) of Section 6.01 occurs
with respect to the Company at a time when the Company is the Paying Agent,  the
Trustee shall automatically assume the duties of Paying Agent.

                  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.

        SECTION  6.04. WAIVER OF PAST  DEFAULTS.  Subject  to Sections  6.07 and
9.02,  the  Holders  of at  least a  majority  of the  principal  amount  of the
outstanding Securities by notice to the Trustee may waive an existing Default or
Event of Default and its  consequences,  except a Default or Event of Default in
payment of  principal  or interest on the  Securities,  including  any  optional
redemption payments or Change of Control or Net Proceeds Offer payments.

        SECTION  6.05. CONTROL  BY  MAJORITY.  The  Holders  of a  majority  in
principal  amount of the  Securities  will  have the  right to direct  the time,
method and place of conducting any  proceeding  for any remedy  available to the
Trustee or exercising  any trust or power  conferred on such  Trustee,  PROVIDED
that (1) such  direction  is not in  conflict  with any rule of law or with this
Indenture  and (2) the Trustee may take any other action  deemed  proper by such
Trustee that is not inconsistent with such direction.

        SECTION 6.06. LIMITATION ON REMEDIES. No Holder of any of the Securities
will have any right to institute any proceeding,  judicial or otherwise,  or for
the  appointment  of a receiver  or  trustee  or pursue  any  remedy  under this
Indenture, unless:

                         (1) such  Holder  has  previously  given  notice to the
                  Trustee of a continuing Event of Default,

                         (2) the  Holders of not less than 25% of the  principal
                  amount of the outstanding Securities have made written request
                  to such  Trustee to institute  proceedings  in respect of such
                  Event  of  Default  in its own  name  as  Trustee  under  this
                  Indenture,

                         (3) such Holder or Holders have offered to such Trustee
                  indemnity  reasonably  satisfactory  to it against  the costs,
                  expenses and  liabilities  to be incurred in  compliance  with
                  such request,

                                                                              46


                         (4) such  Trustee for 60 days after its receipt of such
                  notice, request and offer of indemnity has failed to institute
                  any proceeding, and

                         (5) no direction inconsistent with such written request
                  has been given to such  Trustee  during such 60-day  period by
                  the  Holders  of a  majority  of the  principal  amount of the
                  outstanding Securities.

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

        SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other  provision of this  Indenture,  the Holder of any Securities will have the
right, which is absolute and unconditional,  to receive payment of the principal
of and  interest  on such  Securities  on the stated  maturity  therefor  and to
institute suit for the  enforcement of any such payment,  and such right may not
be impaired without the consent of such Holder.

        SECTION  6.08. COLLECTION  SUIT BY  TRUSTEE.  If an Event of Default in
payment of principal, premium, if any, or interest specified in Section 6.01(1),
(2) or (3) occurs and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express  trust  against the Company or any  Subsidiary
Guarantor  for the whole  amount of  principal,  premium,  if any,  and interest
remaining  unpaid  with  respect  to the  Securities,  and  interest  on overdue
principal and premium,  if any, and, to the extent  lawful,  interest on overdue
interest, and such further amounts as shall be sufficient to cover the costs and
expenses of collection,  including the reasonable  compensation  and expenses of
the Trustee, its agents and counsel.

        SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.(a) 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,  the Subsidiary  Guarantors,
their  creditors  or their  property  and may  collect  and receive any money or
securities or other  property  payable or  deliverable on any such claims and to
distribute the same.

                  (b) Nothing herein  contained shall be deemed to authorize the
Trustee  to  authorize  or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder  thereof,  or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

        SECTION 6.10.  PRIORITIES. If the Trustee collects any money pursuant to
this Article Six, it shall pay out the money in the following order:

                         First:  to the Trustee  for  amounts due under  Section
                  7.07;

                                                                              47


                         Second:  to Holders  for  amounts due and unpaid on the
                  Securities  for  principal  and  interest,   ratably,  without
                  preference  or priority of any kind,  according to the amounts
                  due and payable on the  Securities for principal and interest,
                  respectively; 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.

        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 in the suit of an  undertaking  to pay
the costs of the suit,  and the court in its  discretion  may assess  reasonable
costs,  including  reasonable  attorneys'  fees and expenses,  against any party
litigant  in the suit,  having  due  regard to the  merits and good faith of the
claims or defenses made by the party litigant.  This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit
by  Holders  of more  than  10% in  principal  amount  of the  then  outstanding
Securities.


                                  ARTICLE SEVEN

                                     TRUSTEE

        SECTION 7.01.  DUTIES OF TRUSTEE.(a) If an Event of Default has occurred
and is  continuing,  the Trustee shall exercise such rights and powers vested in
it by this  Indenture and use the same degree of care and skill in such exercise
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

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

                         (1) The Trustee need perform only those duties that are
                  specifically  set forth (or incorporated by reference) in this
                  Indenture and no others.

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

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

                         (1) This  paragraph  (c) does not limit  the  effect of
                  paragraph (b) of this Section.

                                                                              48


                         (2) The  Trustee  shall not be liable  for any error of
                  judgment  made in good  faith by an  officer  of the  Trustee,
                  unless  it  is  proved  that  the  Trustee  was  negligent  in
                  ascertaining the pertinent facts.

                         (3) The  Trustee  shall not be liable  with  respect to
                  action it takes or omits to take in good  faith in  accordance
                  with a direction  received by it pursuant to Section 6.05, and
                  the  Trustee  shall be  entitled  from time to time to request
                  such a direction.

                  (d) Every  provision of this Indenture that in any way relates
to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

                  (e) The Trustee shall be under no obligation and may refuse to
perform any duty or  exercise  any right or power  unless it receives  indemnity
reasonably  satisfactory  to it  against  any loss,  liability  or  expense.  No
provision of this Indenture  shall require the Trustee to expend or risk its own
funds or otherwise  incur  financial  liability in the performance of any of its
duties hereunder or in the exercise of any of its rights or powers,  if it shall
have  reasonable  grounds to believe  that  repayment  of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

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

        SECTION   7.02. RIGHTS  OF   TRUSTEE.   Subject   to   Section   7.01:

                  (a) The Trustee may rely on and shall be  protected  in acting
or refraining from acting upon any document  believed by it to be genuine and to
have been signed or presented  by the proper  person.  The Trustee  shall not be
bound to make  any  investigation  into  the  facts  or  matters  stated  in any
resolution,   certificate,   statement,  instrument,  opinion,  report,  notice,
request, direction,  consent, order, bond, debenture or other paper or document,
but  the  Trustee,  in  its  discretion,   may  make  such  further  inquiry  or
investigation  into such facts or matters as it may see fit, and, if the Trustee
shall  determine  to make such  further  inquiry or  investigation,  it shall be
entitled to examine the books,  records and premises of the Company,  personally
or by agent or attorney,  to the extent  reasonably  required by such inquiry or
investigation.

                  (b) Before the Trustee acts or refrains  from  acting,  it may
require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not
be liable for any action it takes or omits to take in good faith in  reliance on
such certificate or opinion.

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

                                                                             49


                  (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith  which it believes  to be  authorized  or within its
rights or powers.

                  (e) The Trustee may consult with counsel of its  selection and
the advice of such counsel or any Opinion of Counsel  shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and reliance thereon.

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

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


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

        (i) The  Trustee  may request  that the  Company  deliver a  certificate
setting forth the names of individuals  and/or titles of officers  authorized at
such time to take specified actions pursuant to this Indenture.

        SECTION  7.03. INDIVIDUAL  RIGHTS  OF  TRUSTEE.  The  Trustee   in  its
individual  or any other  capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its  Subsidiaries  or Affiliates with
the same rights it would have if it were not Trustee.  Any Agent may do the same
with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

        SECTION 7.04.  TRUSTEE'S DISCLAIMER. The Trustee makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable  for the Company's use of the proceeds from the Securities or any
prospectus,  offering or solicitation documents, and it shall not be responsible
for  any   statement  in  the   Securities   other  than  its   certificate   of
authentication.

        SECTION 7.05.  NOTICE OF DEFAULTS. If a Default occurs and is continuing
and if it is  known  to the  Trustee,  the  Trustee  shall  mail to each  Holder
pursuant  to  Section  11.02 a notice of the  Default  within  90 days  after it
occurs.  Except in the case of a Default  in any  payment on any  Security,  the
Trustee  may  withhold  the  notice  if and so long as the  board of  directors,
executive  committee or a trust  committee of officers in good faith  determines
that withholding the notice is in the interests of Holders.

                                                                              50


        SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.  Within 60 days after each
April 1,  beginning with the April 1 following the date of this  Indenture,  the
Trustee  shall mail to each Holder a brief  report dated as of such April 1 that
complies  with TIA  Section  313(a),  but only if such report is required in any
year under TIA Section  313(a).  The Trustee also shall comply with TIA Sections
313(b) and  313(c).  A copy of each report at the time of its mailing to Holders
shall be filed with the SEC and each stock  exchange on which the Securities are
listed.  The Company  shall  notify the Trustee in writing  when the  Securities
become listed on any national securities exchange or of any delisting thereof.

        SECTION 7.07. COMPENSATION AND INDEMNITY. The Company and the Subsidiary
Guarantors  jointly and  severally  agree to pay the  Trustee  from time to time
reasonable  compensation  for its  services  (which  compensation  shall  not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust). The Company and the Subsidiary  Guarantors jointly and severally
agree to reimburse  the Trustee upon  request for all  reasonable  out-of-pocket
expenses, disbursements and advances incurred by it. Such expenses shall include
when applicable the reasonable compensation and expenses of the Trustee's agents
and counsel.

                  The Trustee shall not be under any obligation to institute any
suit,  or take any  remedial  action  under  this  Indenture,  or to  enter  any
appearance  or in any way defend any suit in which it may be a defendant,  or to
take any steps in the  execution of the trusts  created  hereby or thereby or in
the enforcement of any rights and powers under this Indenture, until it shall be
indemnified  to its  satisfaction  against  any  and  all  reasonable  expenses,
disbursements  and advances  incurred or made by the Trustee in accordance  with
any provisions of this Indenture,  including  compensation for services,  costs,
expenses,  outlays,  counsel  fees and  other  disbursements,  and  against  all
liability  (including fees and expenses  incurred by the Trustee pursuant to the
penultimate  paragraph  of Section  7.08) not due to its  negligence  or willful
misconduct.  The Company and the  Subsidiary  Guarantors  jointly and  severally
agree to indemnify the Trustee  against any loss,  liability,  claim,  damage or
expenses  incurred by it arising out of or in connection with the acceptance and
administration  of the trust and its  duties  hereunder  as  Trustee,  Registrar
and/or  Paying  Agent,  including  the  costs and  expenses  of  enforcing  this
Indenture against the Company  (including with respect to this Section 7.07) and
of  defending  itself  against any claim or  liability  in  connection  with the
exercise or  performance of any of its powers or duties  hereunder.  The Trustee
shall notify the Company and the Subsidiary Guarantors of any claim for which it
may seek indemnity; however, unless the position of the Company is prejudiced by
such  failure,  the failure of the Trustee to promptly  notify the Company shall
not limit its right to indemnification. The Company shall defend each such claim
and the Trustee shall cooperate in the defense.  The Trustee may retain separate
counsel and the Company shall  reimburse the Trustee for the reasonable fees and
expenses of such  counsel.  The  Company  need not pay for any  settlement  made
without its consent.

                                                                              51


                  Neither  the Company nor the  Subsidiary  Guarantors  shall be
obligated  to reimburse  any expense or indemnify  against any loss or liability
incurred by the Trustee through the Trustee's  negligence or willful misconduct.
To secure the payment  obligations of the Company and the Subsidiary  Guarantors
in this Section,  the Trustee shall have a claim prior to that of the Holders of
the Securities on all money or property held or collected by the Trustee, except
that held in trust to pay  principal of and interest on  particular  Securities.
The  Trustee's  right to receive  payment of any amounts due under this  Section
7.07 shall not be  subordinate  to any other  liability or  Indebtedness  of the
Company.

                  When the Trustee incurs expenses or renders services after the
occurrence  of any Event of Default  specified  in Sections  6.01(8) or (9), the
expenses  and the  compensation  for the  services  are  intended to  constitute
expenses of administration under any Bankruptcy Law.

                  The benefits of this section shall survive termination of this
Indenture and resignation or removal of the Trustee.

        SECTION  7.08.  REPLACEMENT  OF  TRUSTEE.  The  Trustee may resign by so
notifying the Company and the Subsidiary uarantors. The Holders of a majority in
principal  amount of the  Securities  may remove the Trustee by so notifying the
Trustee, in writing. The Company may remove the Trustee if:

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

                         (2) the Trustee is adjudged a bankrupt or an insolvent;

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

                         (4) the Trustee becomes  incapable of acting as Trustee
                  hereunder.

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee  for any  reason,  the Company  shall  promptly  appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders  of a majority  in  principal  amount of the  Securities  may  appoint a
successor Trustee to replace the successor Trustee appointed by the Company.

                  A successor Trustee shall deliver a written  acceptance of its
appointment  to the  retiring  Trustee  and to the  Company  and the  Subsidiary
Guarantors.  Immediately  after that,  the retiring  Trustee shall  transfer all
property  held by it as Trustee to the  successor  Trustee,  subject to the lien
provided for in Section 7.07, 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. A successor Trustee shall
mail notice of its succession to each Holder.

                  If a successor  Trustee  does not take  office  within 30 days
after the retiring  Trustee  resigns or is removed,  the retiring  Trustee,  the
Company or the Holders of a majority in principal  amount of the  Securities may
petition any court of competent  jurisdiction for the appointment of a successor
Trustee.

                                                                              52


                  If the Trustee fails to comply with Section  7.10,  any Holder
may petition any court of competent  jurisdiction for the removal of the Trustee
and the appointment of a successor  Trustee.  Any successor Trustee shall comply
with TIA Section 310(a)(5).

        SECTION  7.09. SUCCESSOR  TRUSTEE  BY  MERGER,  ETC.  If   the  Trustee
consolidates,  merges or converts into, or transfers all or substantially all of
its corporate trust assets to, another  corporation,  the successor  corporation
without  any  further  act  shall  be  the  successor  Trustee;   PROVIDED  such
corporation or association shall be otherwise  eligible and qualified under this
Article and shall notify the Company of its successor hereunder.

        SECTION 7.10 ELIGIBILITY;  DISQUALIFICATION. This Indenture shall always
have a Trustee which satisfies the  requirements of TIA Section  310(a)(1).  The
Trustee shall always have a combined capital and surplus of at least $50,000,000
as set  forth in its most  recent  published  annual  report of  condition.  The
Trustee shall also comply with TIA Section 310(b).

        SECTION 7.11.  PREFERENTIAL  COLLECTION OF CLAIMS AGAINST  COMPANY.  The
Trustee   shall  comply  with  TIA  Section   311(a),   excluding  any  creditor
relationship  listed in TIA Section  311(b).  A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                             DISCHARGE OF INDENTURE

        SECTION 8.01.  OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

                  The  Company  may,  at the  option of its  Board of  Directors
evidenced by a resolution  set forth in an Officers'  Certificate,  at any time,
with respect to the Securities,  elect to exercise its rights pursuant to either
Section 8.02 or 8.03 with respect to all outstanding  Securities upon compliance
with the conditions set forth below in this Article Eight.

        SECTION  8.02. LEGAL  DEFEASANCE  AND  DISCHARGE.  Upon  the   Company's
exercise  under Section 8.01 of the option  applicable to this Section 8.02, the
Company  shall be deemed  to have  been  discharged  from its  obligations  with
respect to all outstanding Securities on the date all conditions set forth below
are satisfied  (hereinafter,  "Legal Defeasance").  For this purpose, such Legal
Defeasance  means that the Company  shall be deemed to have paid and  discharged
the entire Indebtedness  represented by the outstanding Securities,  which shall
thereafter be deemed to be  "outstanding"  only for the purposes of Section 8.05
and the other Sections of this Indenture  referred to in (a) and (b) below,  and
to have  satisfied  all its other  obligations  under such  Securities  and this
Indenture  (and the  Trustee,  on demand of and at the  expense of the  Company,
shall  execute  proper  instruments  acknowledging  the  same),  except  for the
following  which  shall  survive  until   otherwise   terminated  or  discharged
hereunder: (a) the rights of Holders of outstanding Securities to receive solely
from the trust fund  described in Section  8.04,  and as more fully set forth in

                                                                              53


such  Section,  payments in respect of the principal  of,  premium,  if any, and
interest  on such  Securities  when such  payments  are due,  (b) the  Company's
obligations  with respect to such Securities  under Sections 2.03,  2.04,  2.06,
2.07, 2.09 and 4.04, (c) the rights,  powers,  trusts,  duties and immunities of
the Trustee  hereunder and the  Company's  obligations  in connection  therewith
(including,  but not  limited  to,  Section  7.07) and (d) this  Article  Eight.
Subject to  compliance  with this  Article  Eight,  the Company may exercise its
option under this Section 8.02  notwithstanding the prior exercise of its option
under Section 8.03 with respect to the Securities.

        SECTION 8.03.  COVENANT  DEFEASANCE.  Upon the Company's  exercise under
Section 8.01 of the option applicable to this Section 8.03, the Company shall be
released  from its  obligations  under the  covenants  contained  in the  second
sentence of Section 4.02,  Sections 4.03,  4.07,  4.08,  4.09, 4.10, 4.11, 4.12,
4.13,  4.14,  4.15 and 4.16 and  Article  Five with  respect to the  outstanding
Securities  on and after the date the  conditions  set forth below are satisfied
(hereinafter,  "Covenant  Defeasance"),  and the Securities  shall thereafter be
deemed not "outstanding" for the purposes of any direction,  waiver,  consent or
declaration  or act  of  Holders  (and  the  consequences  of  any  thereof)  in
connection  with such covenants,  but shall continue to be deemed  "outstanding"
for all other purposes hereunder (it being understood that such Securities shall
not be deemed  outstanding  for  accounting  purposes).  For this purpose,  such
Covenant Defeasance means that, with respect to the outstanding Securities,  the
Company  may omit to comply with and shall have no  liability  in respect of any
term,  condition or limitation set forth in any such covenant,  whether directly
or indirectly,  by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other  document  and such  omission to comply  shall not  constitute a
Default or an Event of Default under Section  6.01(5),  but, except as specified
above,  the remainder of this Indenture and such Securities  shall be unaffected
thereby.  In addition,  upon the  Company's  exercise  under Section 8.01 of the
option  applicable to this Section 8.03,  Sections 6.01(4) through 6.01(9) shall
not constitute Events of Default.

        SECTION 8.04.  CONDITIONS TO LEGAL OR COVENANT DEFEASANCE. The following

Section 7.10 who shall agree to comply with the provisions of this Article Eight
applicable  to it) as  trust  funds in  trust  for the  purpose  of  making  the
following payments,  specifically  pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities, (a) cash in U.S. Legal Tender
in an amount,  or (b) U.S.  Government  Securities  which  through the scheduled
payment of principal and interest in respect  thereof in  accordance  with their
terms will  provide,  not later than one day before the due date of any payment,
cash in U.S. Legal Tender in an amount,  or (c) a combination  thereof,  in such
amounts, as will be sufficient,  in the opinion of a nationally  recognized firm
of independent public accountants  expressed in a written  certification thereof
delivered to the Trustee, to pay and discharge and which shall be applied by the

                                                                              54

premium, if any, and interest on the outstanding Securities on the Maturity Date
or on the applicable  redemption  date, as the case may be, of such principal or
installment of principal,  premium,  if any, or interest and in accordance  with
the terms of this  Indenture and of such  Securities;  PROVIDED that the Trustee
shall have been  irrevocably  instructed  to apply such money or the proceeds of
such U.S. Government Securities to said payments with respect to the Securities.

                  (b) In the case of an election under Section 8.02, the Company
shall have  delivered to the Trustee an Opinion of Counsel  confirming  that (i)
the Company has  received  from,  or there has been  published  by, the Internal
Revenue Service a ruling or (ii) since the date hereof,  there has been a change
in the applicable federal income tax law, in either case to the effect that, and
based thereon such opinion 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  and will be subject to federal
income  tax on the same  amounts,  in the same  manner  and at the same times as
would have been the case if such Legal Defeasance had not occurred;

                  (c) In the case of an election under Section 8.03, the Company
shall have delivered to the Trustee an Opinion of Counsel to the effect 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 and will
be subject to federal income tax on the same amounts,  in the same manner and at
the same times as would have been the case if such Covenant  Defeasance  had not
occurred;

                  (d) No  Default  or  Event  of  Default  with  respect  to the
Securities shall have occurred and be continuing on the date of such deposit or,
insofar as Subsection 6.01(8) or 6.01(9) is concerned, at any time in the period
ending on the 91st day after the date of such deposit (it being  understood that
this  condition  shall not be deemed  satisfied  until  the  expiration  of such
period);

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

                  (f) In the case of any  election  under  Section 8.02 or 8.03,
the Company shall have delivered to the Trustee an Officers' Certificate stating
that the deposit made by the Company pursuant to its election under Section 8.02
or 8.03 was not made by the Company  with the intent of  preferring  the Holders
over other creditors of the Company or with the intent of defeating,  hindering,
delaying or defrauding creditors of the Company or others; and

                  (g)  The  Company  shall  have  delivered  to the  Trustee  an
Officers'  Certificate  and  an  Opinion  of  Counsel,  each  stating  that  all
conditions  precedent provided for relating to either the Legal Defeasance under
Section 8.02 or the Covenant  Defeasance under Section 8.03 (as the case may be)
have been complied with as contemplated by this Section 8.04.

                                                                              55


        SECTION 8.05.  DEPOSITED MONEY AND U.S. GOVERNMENT SECURITIES TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to Section 8.06, all money and
U.S. Government  Securities  (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee,  collectively for purposes of this Section
8.05,  the  "Trustee")  pursuant to Section  8.04 in respect of the  outstanding
Securities shall be held in trust and applied by the Trustee, in accordance with
the provisions of such  Securities and this  Indenture,  to the payment,  either
directly  or through any Paying  Agent  (including  the Company or a  Subsidiary
Guarantor,  if any, acting as Paying Agent) as the Trustee may determine, to the
Holders of such  Securities of all sums due and to become due thereon in respect
of  principal,  premium,  if any,  and  interest,  but  such  money  need not be
segregated from other funds except to the extent required by law.

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

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

        SECTION 8.06. REPAYMENT TO COMPANY. Any money deposited with the Trustee
or any Paying  Agent,  or then held by the Company,  in trust for the payment of
the  principal  of,  premium,  if any, or interest on any Security  which is not
subject to the last paragraph of Section 8.05 and has remained unclaimed for two
years after such principal,  and premium, if any, or interest has become due and
payable  shall  be paid to the  Company  on its  request  (unless  an  abandoned
property law designates  another  Person) or (if then held by the Company) shall
be  discharged  from  such  trust;  and  the  Holder  of such  Securities  shall
thereafter,  as an  unsecured  general  creditor,  look only to the  Company for
payment  thereof,  and all  liability  of the Trustee or such Paying  Agent with
respect  to such  trust  money,  and all  liability  of the  Company  as trustee
thereof,  shall thereupon  cease;  PROVIDED,  however,  that the Trustee or such
Paying  Agent,  before  being  required to make any such  repayment,  may at the
expense of the Company cause to be published once, in the New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified  therein,  which shall not be less than 30 days
from the date of such  publication,  any  unclaimed  balance  of such money then
remaining will be repaid to the Company.

                                                                              56


        SECTION 8.07.  REINSTATEMENT.If the Trustee or Paying Agent is unable to
apply any U.S.  Legal Tender or U.S.  Government  Securities in accordance  with
Section 8.02 or 8.03,  as the case may be, by reason of any order or judgment of
any  court  or  governmental  authority  enjoining,  restraining,  or  otherwise
prohibiting  such  application,   then  the  Company's  obligations  under  this
Indenture  and the  Securities  shall be  revived  and  reinstated  as though no
deposit had  occurred  pursuant  to Section  8.02 or 8.03 until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance  with
Section  8.02 or 8.03,  as the  case may be;  PROVIDED,  HOWEVER,  that,  if the
Company makes any payment of principal of,  premium,  if any, or interest on any
Security  following 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 held by the  Trustee or Paying  Agent.  In the event the
Company's  obligations  under this  Indenture and the Securities are revived and
reinstated  pursuant  to  this  Section  8.07,  then  the  obligations  of  each
Subsidiary  Guarantor  under its Guarantee and this Indenture that were released
pursuant to Section  10.04 as a result of the  Company's  exercise of its rights
under this Article Eight shall be revived and  reinstated as though such release
had not occurred.


                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

        SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.

                  The Company,  the  Subsidiary  Guarantors  and the Trustee may
amend or  supplement  this  Indenture  or the  Securities  without  notice to or
consent of any Holder:

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

                         (2) to comply with Section 5.01;

                         (3)  to  reflect   the   addition  or  release  of  any
                  Subsidiary Guarantor, as provided for by this Indenture;

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

                         (5)  to  make  any  change   that  would   provide  any
                  additional  benefit or rights to the  Holders or that does not
                  adversely  affect  the  rights of any  Holder in any  material
                  respect.

                  Upon the request of the Company and the Subsidiary Guarantors,
accompanied  by a  Board  Resolution  of  the  Company  and of  each  Subsidiary
Guarantor authorizing the execution of any such supplemental indenture, and upon
receipt by the Trustee of the documents  described in Section 9.06,  the Trustee
shall join with the Company and the  Subsidiary  Guarantors  in the execution of
any  supplemental  indenture  authorized  or  permitted  by the  terms  of  this
Indenture and make any further appropriate  agreements and stipulations that may
be therein  contained.  After an amendment or waiver under this Section  becomes
effective,  the  Company  shall mail to the  Holders of each  Security  affected
thereby a notice briefly  describing the amendment or waiver. Any failure of the
Company to mail such notice, or any defect therein,  shall not, however,  in any
way impair or affect the validity of any such supplemental indenture.

                                                                              57


        SECTION 9.02.  WITH CONSENT OF HOLDERS. Except as provided below in this
Section 9.02, the Company,  the Subsidiary  Guarantors and the Trustee may amend
this Indenture or the Securities  with the written consent  (including  consents
obtained in connection with a tender offer or exchange offer for Securities or a
solicitation  of consents in respect of  Securities,  PROVIDED that in each case
such offer or solicitation is made to all Holders of then outstanding Securities
on equal terms) of the Holders of at least a majority of the principal amount of
the outstanding Securities.

                  Upon the request of the Company and the Subsidiary Guarantors,
accompanied by a Board  Resolution of the Company and each Subsidiary  Guarantor
authorizing  the  execution  of any such  supplemental  indenture,  and upon the
filing with the Trustee of evidence of the consent of the Holders as  aforesaid,
and upon  receipt by the Trustee of the Opinion of Counsel  described in Section
9.06, the Trustee shall join with the Company and the  Subsidiary  Guarantors in
the execution of such supplemental indenture.

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

                  The  Holders  of a  majority  of the  principal  amount of the
outstanding  Securities  may waive  compliance  in a particular  instance by the
Company or the Subsidiary Guarantors with any provision of this Indenture or the
Securities  (including  waivers  obtained in  connection  with a tender offer or
exchange  offer for  Securities  or a  solicitation  of  consents  in respect of
Securities, PROVIDED that in each case such offer or solicitation is made to all
Holders of the then outstanding Securities on equal terms). However, without the
consent of each Holder  affected,  an amendment or waiver under this Section may
not:

                         (1)  reduce  the  percentage  of  principal  amount  of
                  Securities   whose  Holders  must  consent  to  an  amendment,
                  supplement or waiver of any provision of this Indenture or the
                  Securities;

                         (2) reduce  the rate or change the time for  payment of
                  interest, including default interest, on the Securities;

                         (3)  reduce the  principal  amount of any  Security  or
                  change the Maturity Date of the Securities;

                         (4) reduce the redemption price,  including premium, if
                  any, payable upon the redemption of any Security or change the
                  time at which any Security may be redeemed;

                         (5) reduce the repurchase price,  including premium, if
                  any,  payable upon the repurchase of any Security  pursuant to
                  Sections  4.11 or  4.16,  or  change  the  time at  which  any
                  Security may or shall be repurchased thereunder;

                                                                              58


                         (6) waive a Default or Event of Default in the  payment
                  of the  principal  of,  premium,  if any,  or  interest on the
                  Securities;

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

                         (8)  impair  the  right  to  institute   suit  for  the
                  enforcement of principal of, premium,  if any, or principal on
                  any  Security  pursuant  to Sections  6.07 or 6.08,  except as
                  limited by Section 6.06; or

                         (9) make any change in Section  6.04 or Section 6.07 or
                  in this sentence of this Section 9.02.

                  The right of any Holder to participate in any consent required
or sought pursuant to any provision of this Indenture (and the obligation of the
Company to obtain any such consent  otherwise  required from such Holder) may be
subject to the requirement that such Holder shall have been the Holder of record
of any Securities with respect to which such consent is required or sought as of
a date identified by the Trustee in a notice  furnished to Holders in accordance
with the terms of this Indenture.

        SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to or
supplement of this Indenture or the ecurities  shall comply with the TIA as then
in effect.

        SECTION 9.04. REVOCATION  AND  EFFECT OF  CONSENTS.  A  consent  to an
amendment,  supplement or waiver by a Holder of a Security shall bind the Holder
and  every  subsequent  Holder of a  Security  or  portion  of a  Security  that
evidences the same debt as the consenting Holder's Security, even if notation of
the consent is not made on any Security. However, until an amendment, supplement
or waiver becomes effective, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security.  For such  revocation to be
effective, the Trustee must receive the notice of revocation before the date the
amendment, supplement or waiver becomes effective.

                  The Company may,  but shall not be obligated  to, fix a record
date for the  purpose of  determining  the  Holders  entitled  to consent to any
amendment  or  waiver.  If the  Company  elects  to fix a  record  date for such
purpose, the record date shall be fixed at (i) the later of 30 days prior to the
first  solicitation  of such  consent  or the  date of the most  recent  list of
Holders furnished to the Trustee prior to such solicitation  pursuant to Section
2.05, or (ii) such other date as the Company shall  designate.  If a record date
is fixed,  then  notwithstanding  the  provisions of the  immediately  preceding
paragraph,  those  Persons  who were  Holders at such record date (or their duly
designated  proxies),  and only those  Persons,  shall be entitled to consent to
such amendment or waiver or to revoke any consent  previously given,  whether or
not such Persons continue to be Holders after such record date. No consent shall
be valid or  effective  for more than 90 days  after  such  record  date  unless
consent  from  the  Holders  of the  principal  amount  of  Securities  required
hereunder  for such  amendment  or waiver to be  effective  also shall have been
given and not revoked within such 90-day period.

                                                                              59


                  After an amendment, supplement or waiver becomes effective, it
shall bind every Holder unless it makes a change described in any of clauses (1)
through (9) of Section  9.02. In that case the  amendment,  supplement or waiver
shall  bind  each  Holder  of a  Security  who  has  consented  to it and  every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security.

        SECTION 9.05.  NOTATION ON OR EXCHANGE OF SENIOR NOTES. If an amendment,
supplement  or waiver  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 about 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  and the  Trustee  shall
authenticate a new Security that reflects the changed terms.

        SECTION 9.06. TRUSTEE PROTECTED. The Trustee shall sign any amendment or
supplement  or waiver  authorized  pursuant to this Article if the  amendment or
supplement or waiver does not adversely affect the rights of the Trustee.  If it
does  adversely  affect the rights of the Trustee,  the Trustee may but need not
sign it. In signing such  amendment or supplement or waiver the Trustee shall be
entitled to receive,  and (subject to Article Seven) shall be fully protected in
relying upon, an Opinion of Counsel stating that such amendment or supplement or
waiver is  authorized  or  permitted by and complies  with this  Indenture.  The
Company may not sign an amendment or supplement until the Boards of Directors of
the Company and the Subsidiary Guarantors approve it.


                                  ARTICLE TEN

                                   GUARANTEES

        SECTION 10.01. UNCONDITIONAL  GUARANTEE.  Each  Subsidiary  Guarantor
hereby,  jointly  and  severally,  fully  and  unconditionally   guarantees,  as
principal  obligor  and not only as surety  (such  guarantee  to be  referred to
herein  as the  "Guarantee"),  to each  Holder  and to the  Trustee  the due and
punctual  payment of the  principal  of,  premium,  if any,  and interest on the
Securities  and all other amounts due and payable  under this  Indenture and the
Securities  by the Company  whether at maturity,  by  acceleration,  redemption,
repurchase or otherwise,  including, without limitation, interest on the overdue
principal of,  premium,  if any, and interest on the  Securities,  to the extent
lawful, all in accordance with the terms hereof and thereof;  subject,  however,
to the limitations set forth in Section 10.05.


                                                                              60


                  Failing  payment  when due of any  amount  so  guaranteed  for
whatever  reason,  the  Subsidiary  Guarantors  will be  jointly  and  severally
obligated to pay the same immediately.  Each Subsidiary  Guarantor hereby agrees
that its  obligations  hereunder  shall be  unconditional,  irrespective  of the
validity,  regularity or enforceability of the Securities or this Indenture, the
absence of any action to enforce  the same,  any waiver or consent by any Holder
of the Securities with respect to any provisions hereof or thereof, the recovery
of any judgment against the Company, any action to enforce the same or any other
circumstance which might otherwise  constitute a legal or equitable discharge or
defense of a guarantor.  Each  Subsidiary  Guarantor  hereby  waives  diligence,
presentment,  demand of  payment,  filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company,  protest,  notice and all demands  whatsoever and covenants
that this Guarantee will not be discharged except by complete performance of the
obligations  contained in the Securities,  this Indenture and in this Guarantee.
If any Holder or the Trustee is required by any court or  otherwise to return to
the Company, any Subsidiary Guarantor, or any custodian,  trustee, liquidator or
other  similar  official  acting in relation  to the  Company or any  Subsidiary
Guarantor,  any amount paid by the Company or any  Subsidiary  Guarantor  to the
Trustee or such Holder,  this Guarantee,  to the extent theretofore  discharged,
shall be reinstated in full force and effect.  Each Subsidiary  Guarantor agrees
it shall not be entitled to any right of  subrogation in relation to the Holders
in respect of any  obligations  guaranteed  hereby until  payment in full of all
obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as
between  each  Subsidiary  Guarantor,  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 Six for the  purposes of this
Guarantee,  notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations  guaranteed  hereby,  and (y) in
the event of any  acceleration  of such  obligations as provided in Article Six,
such obligations (whether or not due and payable) shall forthwith become due and
payable by each Subsidiary Guarantor for the purpose of this Guarantee.

        SECTION 10.02. SUBSIDIARY GUARANTORS MAY CONSOLIDATE,  ETC., ON CERTAIN
TERMS.  (a)  Subject to  paragraph  (b) of this  Section  10.02,  no  Subsidiary
Guarantor may  consolidate or merge with or into (whether or not such Subsidiary
Guarantor is the surviving  Person)  another Person unless (i) the Person formed
by or surviving any such  consolidation or merger (if other than such Subsidiary
Guarantor)  assumes all the obligations of such Subsidiary  Guarantor under this
Indenture and the  Securities  pursuant to a supplemental  indenture,  in a form
reasonably satisfactory to the Trustee, (ii) immediately after such transaction,
no Default or Event of Default exists, (iii) such Subsidiary Guarantor or Person
formed by or surviving any such  consolidation or merger will have  Consolidated
Tangible Net Worth  (immediately after the transaction) equal to or greater than
the  Consolidated  Tangible Net Worth of such Subsidiary  Guarantor  immediately
preceding  the  transaction  and  (iv)  the  Company  will,  at the time of such
transaction  after giving pro forma effect  thereto as if such  transaction  had
occurred at the beginning of the applicable  Reference  Period,  be permitted to
incur at least $1.00 of additional  Indebtedness pursuant to Section 4.09(a). In
connection with any consolidation or merger  contemplated by this Section 10.02,
the  Company  shall  deliver to the  Trustee  prior to the  consummation  of the


                                                                              61


proposed  transaction an Officers'  Certificate  to the foregoing  effect and an
Opinion of Counsel stating that the proposed  transaction and such  supplemental
indenture comply with this Indenture.  This Section 10.02(a) will not prohibit a
merger  between  Subsidiary  Guarantors  or a merger  between  the Company and a
Subsidiary Guarantor.

        (b) In the event of a sale or other  disposition of all or substantially
all of the assets of any Subsidiary  Guarantor or a sale or other disposition of
all of the Capital  Stock of such  Subsidiary  Guarantor,  in any case by way of
merger, consolidation or otherwise, then such Subsidiary Guarantor (in the event
of a sale or  other  disposition,  by way of  such a  merger,  consolidation  or
otherwise,  of all of the Capital  Stock of such  Subsidiary  Guarantor)  or the
Person acquiring the assets (in the event of a sale or other  disposition of all
or  substantially  all of the  assets  of  such  Subsidiary  Guarantor)  will be
released and relieved of any obligations under its Guarantees;  PROVIDED that in
the event such sale or disposition  constitutes an Asset Sale, the Net Available
Proceeds of such sale or other  disposition  are applied in accordance  with the
provisions of this Indenture described under Section 4.11.

        SECTION 10.03. ADDITION OF SUBSIDIARY GUARANTORS. (a) The Company agrees
to cause each  Subsidiary  that shall become a Restricted  Subsidiary  after the
Issue Date to execute and  deliver a  supplemental  indenture  pursuant to which
such  Restricted  Subsidiary  shall  guarantee  the  payment  of the  Securities
pursuant to the terms hereof.

        (b) Any Person that was not a Subsidiary Guarantor on the Issue Date may
become a Subsidiary  Guarantor by executing and  delivering to the Trustee (i) a
supplemental  indenture in form and substance satisfactory to the Trustee, which
subjects  such  Person to the  provisions  (including  the  representations  and
warranties) of this  Indenture as a Subsidiary  Guarantor and (ii) an Opinion of
Counsel and Officers' Certificate to the effect that such supplemental indenture
has been duly  authorized and executed by such Person and constitutes the legal,
valid  and  binding  obligation  of  such  Person  (subject  to  such  customary
exceptions  concerning  creditors'  rights and  equitable  principles  as may be
acceptable to the Trustee in its discretion and provided that no opinion need be
rendered concerning the enforceability of the Guarantee).

        SECTION 10.04. RELEASE OF A SUBSIDIARY  GUARANTOR.  Upon (i) the sale or
disposition  of a  Subsidiary  Guarantor  (or  all or  substantially  all of its
assets) or (ii) the  designation  of a Subsidiary  Guarantor as an  Unrestricted
Subsidiary, in each case which is otherwise in compliance with the terms of this
Indenture,  including but not limited to the provisions of Section  10.02,  such
Subsidiary  Guarantor  shall be deemed  released  from all of its  Guarantee and
related obligations in this Indenture without any further action by the Trustee,
the Company or such  Subsidiary  Guarantor.  Subject to Section  8.07,  upon the
Company's election, in compliance with the conditions set forth in Article Eight
hereof,  to exercise  its rights  pursuant to either  Section  8.02 or 8.03 with
respect to all outstanding Securities, each Subsidiary Guarantor shall be deemed
released  from all of its Guarantee and related  obligations  in this  Indenture
without  any  further  action by the  Trustee,  the  Company  or any  Subsidiary
Guarantor.  The Trustee shall deliver an appropriate  instrument evidencing such

                                                                              62


release  upon  receipt of a request by the Company  accompanied  by an Officers'
Certificate and, in the case of the release of a Subsidiary  Guarantor  pursuant
to clause (i) of the first sentence of this Section 10.04, an Opinion of Counsel
certifying  that  such  sale or other  disposition  was made by the  Company  in
accordance with the provisions of this Indenture.  Any Subsidiary  Guarantor not
so released  remains  liable for the full amount of principal of and interest on
the Securities as provided in this Article Ten.

        SECTION 10.05. LIMITATION OF SUBSIDIARY  GUARANTOR'S  LIABILITY.   Each
Subsidiary Guarantor,  and by its acceptance hereof each Holder, hereby confirms
that  it is the  intention  of all  such  parties  that  the  guarantee  by such
Subsidiary  Guarantor  pursuant to its  Guarantee  not  constitute  a fraudulent
transfer or  conveyance  for purposes of any  federal,  state or foreign law. To
effectuate the foregoing  intention,  the Holders and each Subsidiary  Guarantor
hereby irrevocably agree that the obligations of each Subsidiary Guarantor under
the  Guarantee  shall be limited to the  maximum  amount as will,  after  giving
effect  to all  other  contingent  and  fixed  liabilities  of  such  Subsidiary
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other  Subsidiary  Guarantor in respect of the  obligations  of
such other  Subsidiary  Guarantor  under its  Guarantee  or  pursuant to Section
10.06,  result  in the  obligations  of  such  Subsidiary  Guarantor  under  the
Guarantee not constituting a fraudulent  conveyance or fraudulent transfer under
federal,  state or foreign  law.  This  Section  10.05 is for the benefit of the
creditors  of  each  Subsidiary  Guarantor,  and,  for  purposes  of  applicable
fraudulent  transfer  and  fraudulent  conveyance  law,  any  Indebtedness  of a
Subsidiary  Guarantor pursuant to Credit Facilities shall be deemed to have been
incurred prior to the incurrence by such  Subsidiary  Guarantor of its liability
under the Guarantee.

        SECTION 10.06. CONTRIBUTION.  In order to provide for just and equitable
contribution among the Subsidiary  Guarantors,  the Subsidiary Guarantors agree,
inter  se,  that  in the  event  any  payment  or  distribution  is  made by any
Subsidiary Guarantor (a "Funding  Guarantor") under the Guarantee,  such Funding
Guarantor  shall be  entitled  to a  contribution  from  each  other  Subsidiary
Guarantor  in a pro  rata  amount  based  on the  Adjusted  Net  Assets  of each
Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages
and expenses  incurred by the Funding  Guarantor in  discharging  the  Company's
obligations with respect to the Securities or any other  Subsidiary  Guarantor's
obligations with respect to the Guarantee.

        SECTION 10.07. [INTENTIONALLY OMITTED.]

        SECTION 10.08. SEVERABILITY.  In case any provision of this  Guarantee
shall be invalid, illegal or unenforceable,  that portion of such provision that
is not  invalid,  illegal  or  unenforceable  shall  remain in  effect,  and the
validity,  legality, and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.


                                                                              63

                                  MISCELLANEOUS

        SECTION 11.01. TRUST  INDENTURE  ACT  CONTROLS.  Whether  prior  to or
following the qualification of this Indenture under the TIA, if any provision of
this  Indenture  limits,  qualifies,  or  conflicts  with the duties  imposed by
operation of TIA Section 318(c) upon an indenture  qualified  under the TIA, the
imposed duties shall control under this Indenture.

(other than the provisions set forth in Section 2.4), a Global  Security may not

Depository  or by a nominee  of the  Depository  to the  Depository  or  another
nominee  of  the  Depository  or by the  Depository  or any  such  nominee  to a

                  (iii)  In the  event  that a  Restricted  Global  Security  is
exchanged for Securities in certificated registered form pursuant to Section 2.4
of this Appendix,  prior to the  consummation of a Registered  Exchange Offer or
the  effectiveness  of a  Shelf  Registration  Statement  with  respect  to such
Securities,  such  Securities  may be  exchanged  only in  accordance  with such
procedures as are  substantially  consistent with the provisions of this Section
2.3 (including the  certification  requirements  set forth on the reverse of the
Initial Securities  intended to ensure that such transfers comply with Rule 144A
or Regulation S, as the case may be) and such other  procedures as may from time
to time be adopted by the Company.

                  OFFERED,  SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH

                  UNDER THE  SECURITIES  ACT PROVIDED BY RULE 144 THEREUNDER (IF
                  AVAILABLE)  OR  (V)  PURSUANT  TO  AN  EFFECTIVE  REGISTRATION
                  STATEMENT  UNDER  THE  SECURITIES  ACT,  IN EACH OF CASES  (I)

                  AND  EACH  SUBSEQUENT   HOLDER  IS  REQUIRED  TO,  NOTIFY  ANY
                  PURCHASER OF THIS SECURITY FROM IT OF THE RESALE  RESTRICTIONS

                  (ii)  Upon  any  sale or  transfer  of a  Transfer  Restricted
        Security (including any Transfer  Restricted  Security  represented by a
        Restricted  Global  Security)  pursuant to Rule 144 under the Securities
        Act, the Registrar shall permit the transferee  thereof to exchange such
        Transfer Restricted  Security for a certificated  Security that does not
        bear the legend  set forth  above and  rescind  any  restriction  on the
        transfer of such Transfer Restricted Security, if the transferor thereof
        certifies  in writing to the  Registrar  that such sale or transfer  was
        made in reliance on Rule 144 (such  certification  to be in the form set
        forth on the reverse of the Security).

                  (iii) After a transfer of any  Initial  Securities  or Private
        Exchange   Securities   pursuant   to  and  during  the  period  of  the
        effectiveness  of a Shelf  Registration  Statement  with respect to such
        Initial Securities or Private Exchange  Securities,  as the case may be,
        all requirements  pertaining to legends on such Initial Security or such
        Private  Exchange   Security  will  cease  to  apply,  the  requirements
        requiring any such Initial  Security or such Private  Exchange  Security
        issued to certain  Holders be issued in global form will cease to apply,
        and a certificated  Initial Security or Private Exchange  Security or an
        Initial  Security or Private  Exchange  Security in global form, in each
        case  without  restrictive  transfer  legends,  will be available to the
        transferee of the Holder of such Initial  Securities or Private Exchange
        Securities  upon  exchange of such  transferring  Holder's  certificated
        Initial Security or Private Exchange  Security or directions to transfer
        such Holder's interest in the Global Security, as applicable.


                                                                             A-6


                  (iv) Upon the consummation of a Registered Exchange Offer with
        respect to the Initial Securities,  all requirements  pertaining to such
        Initial  Securities that Initial Securities issued to certain Holders be
        issued in global form will still  apply with  respect to Holders of such
        Initial  Securities that do not exchange their Initial  Securities,  and
        Exchange  Securities in certificated or global form will be available to
        Holders  that  exchange  such  Initial  Securities  in  such  Registered
        Exchange Offer.

                  (v) Upon the  consummation of a Private  Exchange with respect
        to the Initial Securities,  all requirements  pertaining to such Initial

        Securities  that do not exchange their Initial  Securities,  and Private
        Exchange Securities in global form with the global securities legend and
        the Restricted  Securities  Legend set forth in Exhibit 1 hereto will be
        available  to Holders that  exchange  such  Initial  Securities  in such
        Private Exchange.

        (c) CANCELLATION OR ADJUSTMENT OF GLOBAL  SECURITY.  At such time as all
beneficial  interests  in a Global  Security  have  either  been  exchanged  for
certificated Securities,  redeemed,  purchased or canceled, such Global Security
shall be returned to the Depository for  cancelation or retained and canceled by
the Trustee.  At any time prior to such cancelation,  if any beneficial interest
in a  Global  Security  is  exchanged  for  certificated  Securities,  redeemed,
purchased or canceled,  the principal  amount of Securities  represented by such
Global  Security  shall be reduced and an adjustment  shall be made on the books
and  records of the  Trustee (if it is then the  Securities  Custodian  for such
Global  Security)  with respect to such Global  Security,  by the Trustee or the
Securities Custodian, to reflect such reduction.

        transfer or  exchange,  but the  Company  may  require  payment of a sum
        sufficient   to  cover  any  transfer  tax,   assessments,   or  similar
        governmental charge payable in connection therewith (other than any such
        transfer taxes,  assessments or similar governmental charge payable upon
        exchange  or  transfer  pursuant  to  Sections  3.06  and  4.16  of  the
        Indenture).

        repurchase  or redeem  Securities or 15 Business Days before an interest
        payment date.


                                                                             A-7

        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 of and interest 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.

                  (v) All  Securities  issued  upon  any  transfer  or  exchange
        pursuant to the terms of this Indenture shall evidence the same debt and
        shall be  entitled  to the same  benefits  under this  Indenture  as the
        Securities surrendered upon such transfer or exchange.

        (e)   NO OBLIGATION OF THE TRUSTEE.

                  (i) The Trustee shall have no  responsibility or obligation to
        any beneficial owner of a Global Security,  Agent Member or other Person
        with  respect to the  accuracy of the records of the  Depository  or its
        nominee or of any Agent Member,  with respect to any ownership  interest
        in the  Securities  or with respect to the delivery to any Agent Member,
        beneficial  owner or other  Person  (other than the  Depository)  of any

        communications to be given to the Holders and all payments to be made to
        Holders under the Securities  shall be given or made only to or upon the
        order of the  registered  Holders  (which shall be the Depository or its
        nominee  in the case of a Global  Security).  The  rights of  beneficial
        owners in any  Global  Security  shall be  exercised  only  through  the
        Depository  subject  to  the  applicable  rules  and  procedures  of the
        Depository. The Trustee may rely and shall be fully protected in relying
        upon  information  furnished by the Depository with respect to its Agent
        Member and any beneficial owners.

                  (ii) The Trustee  shall have no obligation or duty to monitor,
        determine or inquire as to compliance with any  restrictions on transfer
        imposed under this Indenture or under applicable law with respect to any
        transfer  of any  interest  in any  Security  (including  any  transfers

                           6.375% Senior Note due 2015

1.      INTEREST

                  Chesapeake Energy Corporation,  an Oklahoma  corporation (such
corporation,  and its  successors  and assigns under the  Indenture  hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal  amount of this Security at the rate per annum shown above;  PROVIDED,
HOWEVER,  that if a Registration  Default (as defined in the Registration Rights
Agreement) occurs, additional interest will accrue on this Security at a rate of
0.50%  per annum  (increasing  by an  additional  0.50%  per  annum  after  each
consecutive  90-day period that occurs after the date on which such Registration
Default  occurs  up to a maximum  additional  interest  rate of 2.00%)  from and
including  the date on which any such  Registration  Default  shall occur to but
excluding  the date on which all  Registration  Defaults  have been  cured.  The
Company will pay interest  semiannually on June 15 and December 15 of each year,
commencing  June 15, 2004.  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 December 8, 2004.  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 June 1 or December 1 next  preceding  the  interest
payment date even if  Securities  are  canceled  after the record date and on or
before the interest payment date. Holders must surrender  Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United  States  that at the time of payment is legal  tender for
payment of public  and  private  debts.  Payments  in respect of the  Securities
represented by a Global  Security  (including  principal,  premium and interest)
will be made by wire  transfer of  immediately  available  funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including  principal,  premium and interest)
by mailing a check to the registered  address of each Holder thereof;  PROVIDED,
HOWEVER,  that payments on a certificated Security will be made by wire transfer
to a U.S.  dollar  account  maintained  by the payee  with a bank in the  United
States if such Holder elects  payment by wire transfer by giving  written notice
to the Trustee or the Paying  Agent to such effect  designating  such account no
later than 30 days  immediately  preceding the relevant due date for payment (or
such other date as the Trustee may accept in its discretion).

3.      PAYING AGENT AND REGISTRAR

                  Initially,  The  Bank  of New  York  Trust  Company,  N.A.,  a
national  banking  association  (the  "Trustee"),  will act as Paying  Agent and
Registrar.  The Company may appoint and change any Paying  Agent,  Registrar  or
co-registrar without notice. The Company or any of its domestically incorporated
Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

                                                                             B-4


4.      INDENTURE

                  The Company issued the Securities  under an Indenture dated as
of December 8, 2004 ("Indenture"),  among the Company, the Subsidiary Guarantors
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

herein have the meanings  ascribed thereto in the Indenture.  The Securities are
subject to all such terms, and Holders are referred to the Indenture and the Act
for a statement of those terms.

                  The Company shall be entitled,  subject to its compliance with
Section 4.09(a) of the Indenture,  to issue  Additional  Securities  pursuant to
Section 2.13 of the Indenture.  The Initial Securities issued on the Issue Date,
any  Additional  Securities  and all  Exchange  Securities  or Private  Exchange
Securities issued in exchange therefor will be treated as a single class for all
purposes under the Indenture.

discretion, up to 35% of the aggregate principal amount of the Securities (which

Offerings at a redemption price of 106.375% of the aggregate principal amount of
the Securities so redeemed,  plus accrued and unpaid  interest on the Securities
so redeemed to the redemption date; PROVIDED,  HOWEVER, that (i) the date of any
such  redemption  occurs within the 90-day  period after the Equity  Offering in
respect  of  which  such  redemption  is  made  and  (ii)  following  each  such
redemption,  at least 65% of the aggregate  principal  amount of the  Securities

                                                                             B-5

this  paragraph  7 shall be made,  to the  extent  applicable,  pursuant  to the
provisions of Sections 3.01 through 3.06 of the Indenture.

8.      NOTICE OF REDEMPTION

                  Notice of redemption will be mailed to the Holder's registered
address at least 30 days but not more than 60 days before the redemption date to
each Holder of Securities to be redeemed.  If less than all Securities are to be
redeemed,  the Trustee shall select pro rata, by lot or, if the  Securities  are
listed  on any  securities  exchange,  by any  other  method  that  the  Trustee
considers fair and appropriate  and that complies with the  requirements of such
exchange,  the  Securities  to be redeemed  in  multiples  of $1,000;  PROVIDED,
HOWEVER,  that no Securities  with a principal  amount of $1,000 or less will be
redeemed in part. Securities in denominations larger than $1,000 may be redeemed
in part.  On and  after  the  redemption  date,  interest  ceases  to  accrue on
Securities or portions of them called for  redemption  (unless the Company shall
default in the payment of the redemption price or accrued interest).

9.      CHANGE OF CONTROL OFFER

                  In the  event of a  Change  of  Control  of the  Company,  the

purchase  all or any  portion  of  each  Holder's  Securities,  at  100%  of the
principal  amount thereof,  plus accrued and unpaid interest to the Net Proceeds
Payment Date.

11.     RESTRICTIVE COVENANTS

                  The  Indenture  imposes  certain  limitations  on, among other
things, the ability of the Company to merge or consolidate with any other Person
or sell, lease or otherwise  transfer all or substantially all of its properties
or assets, the ability of the Company or the Restricted  Subsidiaries to dispose
of assets,  to pay dividends and make certain other  distributions and payments,
to make certain investments or redeem,  retire,  repurchase or acquire for value
shares of Capital Stock, to incur additional  Indebtedness or incur encumbrances
against certain property and to enter into certain transactions with Affiliates,
all subject to certain limitations described in the Indenture.

                                                                             B-6

12.     RANKING AND GUARANTEES

                  The Securities are general senior unsecured obligations of the
Company.  The  Company's  obligation  to pay  principal,  premium,  if any,  and
interest  with respect to the  Securities  is  unconditionally  guaranteed  on a
senior basis,  jointly and severally,  by the Subsidiary  Guarantors pursuant to
Article Ten of the  Indenture.  Certain  limitations  to the  obligations of the
Subsidiary Guarantors are set forth in further detail in the Indenture.

13.     DENOMINATIONS; TRANSFER; EXCHANGE

                  The  Securities  are in  registered  form  without  coupons in
denominations of $1,000 principal amount and whole multiples of $1,000. A Holder
may  transfer or exchange  Securities  in  accordance  with the  Indenture.  The
Registrar  may require a Holder,  among  other  things,  to furnish  appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the  Indenture.  The Registrar need not register the transfer of
or exchange of any Securities  selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or any  Securities  for a period of 15  Business  Days  before the  mailing of a
notice of an offer to repurchase or redeem Securities or 15 Business Days before
an interest payment date.

14.     PERSONS DEEMED OWNERS

                  The  registered  Holder of this Security may be treated as the
owner of it for all purposes.

15.     UNCLAIMED MONEY

                  If money for the  payment of  principal  or  interest  remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned  property law designates  another
Person. After any such payment,  Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

16.     DISCHARGE AND DEFEASANCE

                  Subject to certain  conditions,  the Company at any time shall
be entitled to terminate some or all of its obligations under the Securities and
the Indenture if the Company deposits with the Trustee money or U.S.  Government
Securities  for the  payment of  principal  and  interest on the  Securities  to
redemption or maturity, as the case may be.

                                                                             B-7


17.     AMENDMENT, SUPPLEMENT, WAIVER

                  Subject to certain exceptions, the Indenture or the Securities
may be amended or  supplemented  with the  consent of the  Holders of at least a
majority of the outstanding  principal  amount of the  Securities,  and any past
default or  noncompliance  with any  provision may be waived with the consent of
the Holders of a majority in  principal  amount of the  Securities.  Without the
consent of any Holder,  the Company may amend or supplement the Indenture or the
Securities to, among other things,  cure any ambiguity,  defect or inconsistency
or to make any change that does not adversely affect the rights of any Holder in
any material respect.

18.     SUCCESSOR CORPORATION

                  When a successor  corporation  assumes all the  obligations of
its  predecessor  under  the  Securities  and  the  Indenture,  the  predecessor
corporation will be released from those obligations.

19.     DEFAULTS AND REMEDIES

                  An Event of Default  generally  is:  default by the Company or
any Subsidiary  Guarantor for 30 days in payment of interest on the  Securities;
default by the Company or any  Subsidiary  Guarantor in payment of principal of,
or premium, if any, on the Securities;  default by the Company or any Subsidiary
Guarantor in the deposit of any optional  redemption or repurchase  payment when
due and payable; defaults resulting in acceleration prior to maturity of certain
other  Indebtedness  or resulting  from payment  defaults  under  certain  other
Indebtedness;  failure by the Company or any  Subsidiary  Guarantor  for 45 days
after  notice  to  comply  with any of its other  agreements  in the  Indenture;
certain final judgments  against the Company or  Subsidiaries;  a failure of any
Guarantee of a Subsidiary  Guarantor to be in full force and effect or denial by
any Subsidiary  Guarantor of its obligations with respect  thereto;  and certain
events of  bankruptcy  or  insolvency.  Subject  to certain  limitations  in the
Indenture,  if an Event of Default occurs and is continuing,  the Trustee or the
Holders of at least 25% in principal amount of the then  outstanding  Securities
may declare all the Securities to be due and payable immediately, except that in
the case of an Event of  Default  arising  from  certain  events of  bankruptcy,
insolvency or  reorganization,  all outstanding  Securities shall become due and
payable  immediately  without further action or notice.  Holders may not enforce
the Indenture or the Securities except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations,  Holders of a majority in principal
amount of the  Securities may direct the Trustee in its exercise of any trust or
power. The Company must furnish an annual compliance certificate to the Trustee.

                                                                             B-8


20.     TRUSTEE DEALINGS WITH COMPANY AND SUBSIDIARY GUARANTORS

                  The Trustee  under the  Indenture,  in its  individual  or any
other capacity,  may become the owner or pledgee of Securities and may otherwise
deal  with  the  Company,   the  Subsidiary   Guarantors  or  their   respective
Subsidiaries  or  Affiliates  with the same  rights it would have if it were not
Trustee.

21.     NO RECOURSE AGAINST OTHERS

                  A director,  officer, employee or stockholder, as such, of the
Company,  any  Subsidiary  Guarantor or the Trustee shall not have any liability
for any  obligations  of the Company,  any  Subsidiary  Guarantor or the Trustee
under the  Securities  or the Indenture or for any claim based on, in respect of
or by reason of, such obligations or their creation.  Each Holder by accepting a
Security waives and releases all such liability. The waiver and release are part
of the consideration for the issue of the Security.

22.     AUTHENTICATION

                  This  Security  shall  not be valid  until the  Trustee  or an
authenticating  agent signs the certificate of  authentication on the other side
of this Security.

                           6.375% Senior Note due 2015

1.      INTEREST

                  Chesapeake Energy Corporation,  an Oklahoma  corporation (such
corporation,  and its  successors  and assigns under the  Indenture  hereinafter
referred to, being herein called the "Company"), promises to pay interest on the
principal  amount of this Security at the rate per annum shown above;  PROVIDED,
HOWEVER,  that if a Registration  Default (as defined in the Registration Rights
Agreement) occurs, additional interest will accrue on this Security at a rate of
0.50%  per annum  (increasing  by an  additional  0.50%  per  annum  after  each
consecutive  90-day period that occurs after the date on which such Registration
Default  occurs  up to a maximum  additional  interest  rate of 2.00%)  from and
including  the date on which any such  Registration  Default  shall occur to but
excluding  the date on which all  Registration  Defaults  have been cured.** The
Company will pay interest  semiannually on June 15 and December 15 of each year,
commencing  June 15, 2005.  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 December 8, 2004.  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 June 1 or December 1 next  preceding  the  interest
payment date even if  Securities  are  canceled  after the record date and on or
before the interest payment date. Holders must surrender  Securities to a Paying
Agent to collect principal payments. The Company will pay principal and interest
in money of the United  States  that at the time of payment is legal  tender for
payment of public  and  private  debts.  Payments  in respect of the  Securities
represented by a Global  Security  (including  principal,  premium and interest)
will be made by wire  transfer of  immediately  available  funds to the accounts
specified by The Depository Trust Company. The Company will make all payments in
respect of a certificated Security (including  principal,  premium and interest)
by mailing a check to the registered  address of each Holder thereof;  PROVIDED,
HOWEVER,  that payments on a certificated Security will be made by wire transfer
to a U.S.  dollar  account  maintained  by the payee  with a bank in the  United
States if such Holder elects  payment by wire transfer by giving  written notice
to the Trustee or the Paying  Agent to such effect  designating  such account no
later than 30 days  immediately

- -----------------------------

     ** Insert if at the date of  issuance of the  Exchange  Security or Private
Exchange Scurity (as the case may be) any Registration Default has occurred with
respect to the related  Initial  Securities  during the interest period in which
such date of  issuance  occurs.


                                                                             C-4


preceding  the relevant due date for payment  (orsuch  other date as the Trustee
may accept in its discretion).

3.      PAYING AGENT AND REGISTRAR

                  Initially,  The  Bank  of New  York  Trust  Company,  N.A.,  a
national  banking  association  (the  "Trustee"),  will act as Paying  Agent and
Registrar.  The Company may appoint and change any Paying  Agent,  Registrar  or
co-registrar without notice. The Company or any of its domestically incorporated
Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.      INDENTURE

                  The Company issued the Securities  under an Indenture dated as
of December 8, 2004 ("Indenture"),  among the Company, the Subsidiary Guarantors
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 of 1939 (15 U.S.C.  ss.ss.  77aaa-77bbbb) as in effect on the date
of the  Indenture  (the "Act").  Terms  defined in the Indenture and not defined
herein have the meanings  ascribed thereto in the Indenture.  The Securities are
subject to all such terms, and Holders are referred to the Indenture and the Act
for a statement of those terms.

Section 4.09(a) of the Indenture,  to issue  Additional  Securities  pursuant to
Section 2.13 of the Indenture.  The Initial Securities issued on the Issue Date,
any  Additional  Securities  and all  Exchange  Securities  or Private  Exchange
Securities issued in exchange therefor will be treated as a single class for all
purposes under the Indenture.

its  option,  redeem all or any  portion of the  Securities  at the  "Make-Whole

                  Notice of redemption will be mailed to the Holder's registered
address at least 30 days but not more than 60 days before the redemption date to

redeemed,  the Trustee shall select pro rata, by lot or, if the  Securities  are
listed  on any  securities  exchange,  by any  other  method  that  the  Trustee
considers fair and appropriate  and that complies with the  requirements of such
exchange,  the  Securities  to be redeemed  in  multiples  of $1,000;  PROVIDED,
HOWEVER,  that no Securities  with a principal  amount of $1,000 or less will be
redeemed in part. Securities in denominations larger than $1,000 may be redeemed

                  In the  event of a  Change  of  Control  of the  Company,  the

principal  amount thereof,  plus accrued and unpaid interest to the Net Proceeds
Payment Date.

11.     RESTRICTIVE COVENANTS

                  The  Indenture  imposes  certain  limitations  on, among other
things, the ability of the Company to merge or consolidate with any other Person
or sell, lease or otherwise  transfer all or substantially all of its properties
or assets, the ability of the Company or the Restricted  Subsidiaries to dispose
of assets,  to pay dividends and make certain other  distributions and payments,

shares of Capital Stock, to incur additional  Indebtedness or incur encumbrances
against certain property and to enter into certain transactions with Affiliates,
all subject to certain limitations described in the Indenture.

12.     RANKING AND GUARANTEES

                  The Securities are general senior unsecured obligations of the
Company.  The  Company's  obligation  to pay  principal,  premium,  if any,  and
interest  with respect to the  Securities  is  unconditionally  guaranteed  on a
senior basis,  jointly and severally,  by the Subsidiary  Guarantors pursuant to
Article Ten of the  Indenture.  Certain  limitations  to the  obligations of the
Subsidiary Guarantors are set forth in further detail in the Indenture.

13.     DENOMINATIONS; TRANSFER; EXCHANGE

                  The  Securities  are in  registered  form  without  coupons in
denominations of $1,000 principal amount and whole multiples of $1,000. A Holder
may  transfer or exchange  Securities  in  accordance  with the  Indenture.  The
Registrar  may require a Holder,  among  other  things,  to furnish  appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the  Indenture.  The Registrar need not register the transfer of
or exchange of any Securities  selected for redemption (except, in the case of a
Security to be redeemed in part, the portion of the Security not to be redeemed)
or any  Securities  for a period of 15  Business  Days  before the  mailing of a
notice of an offer to repurchase or redeem Securities or 15 Business Days before
an interest payment date.

14.     PERSONS DEEMED OWNERS

                  The  registered  Holder of this Security may be treated as the
owner of it for all purposes.


                                                                             C-7


15.     UNCLAIMED MONEY

                  If money for the  payment of  principal  or  interest  remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned  property law designates  another
Person. After any such payment,  Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

16.     DISCHARGE AND DEFEASANCE

                  Subject to certain  conditions,  the Company at any time shall
be entitled to terminate some or all of its obligations under the Securities and
the Indenture if the Company deposits with the Trustee money or U.S.  Government
Securities  for the  payment of  principal  and  interest on the  Securities  to
redemption or maturity, as the case may be.

17.     AMENDMENT, SUPPLEMENT, WAIVER

                  Subject to certain exceptions, the Indenture or the Securities
may be amended or  supplemented  with the  consent of the  Holders of at least a
majority of the outstanding  principal  amount of the  Securities,  and any past
default or  noncompliance  with any  provision may be waived with the consent of
the Holders of a majority in  principal  amount of the  Securities.  Without the
consent of any Holder,  the Company may amend or supplement the Indenture or the
Securities to, among other things,  cure any ambiguity,  defect or inconsistency
or to make any change that does not adversely affect the rights of any Holder in
any material respect.

18.     SUCCESSOR CORPORATION

                  When a successor  corporation  assumes all the  obligations of
its  predecessor  under  the  Securities  and  the  Indenture,  the  predecessor
corporation will be released from those obligations.

19.     DEFAULTS AND REMEDIES

                  An Event of Default  generally  is:  default by the Company or
any Subsidiary  Guarantor for 30 days in payment of interest on the  Securities;
default by the Company or any  Subsidiary  Guarantor in payment of principal of,
or premium, if any, on the Securities;  default by the Company or any Subsidiary
Guarantor in the deposit of any optional  redemption or repurchase  payment when
due and payable; defaults resulting in acceleration prior to maturity of certain
other  Indebtedness  or resulting  from payment  defaults  under  certain  other
Indebtedness;  failure by the Company or any  Subsidiary  Guarantor  for 45 days
after  notice  to  comply  with any of its other  agreements  in the  Indenture;
certain final judgments  against the Company or  Subsidiaries;  a failure of any
Guarantee of a Subsidiary  Guarantor to be in full force and effect or denial by
any Subsidiary  Guarantor of its obligations with respect  thereto;  and certain
events of  bankruptcy  or  insolvency.  Subject  to certain  limitations  in the
Indenture,  if an Event of Default occurs and is continuing,  the Trustee or the
Holders of at least 25% in principal amount of the then  outstanding  Securities
may declare all the Securities to be due and payable immediately, except that in
the case of an Event of  Default  arising  from  certain  events of  bankruptcy,
insolvency or  reorganization,  all outstanding  Securities shall become due and
payable  immediately  without further action or notice.  Holders may not enforce
the Indenture or the Securities except as provided in the Indenture. The Trustee
may require indemnity satisfactory to it before it enforces the Indenture or the
Securities.  Subject to certain limitations,  Holders of a majority in principal
amount of the  Securities may direct the Trustee in its exercise of any trust or
power. The Company must furnish an annual compliance certificate to the Trustee.


                                                                             C-8


20.     TRUSTEE DEALINGS WITH COMPANY AND SUBSIDIARY GUARANTORS

                  The Trustee  under the  Indenture,  in its  individual  or any
other capacity,  may become the owner or pledgee of Securities and may otherwise
deal  with  the  Company,   the  Subsidiary   Guarantors  or  their   respective
Subsidiaries  or  Affiliates  with the same  rights it would have if it were not
Trustee.

21.     NO RECOURSE AGAINST OTHERS

                  A director,  officer, employee or stockholder, as such, of the
Company,  any  Subsidiary  Guarantor or the Trustee shall not have any liability
for any  obligations  of the Company,  any  Subsidiary  Guarantor or the Trustee
under the  Securities  or the Indenture or for any claim based on, in respect of
or by reason of, such obligations or their creation.  Each Holder by accepting a
