with  acquisitions of Properties  from such Person (other than any  Indebtedness
incurred in connection  with,  or in  contemplation  of, such Person  becoming a

independent  petroleum  engineers in a reserve report  prepared as of the end of
the Company's most recently  completed  fiscal year for which audited  financial

estimated  discounted  future net revenues from (1) estimated proved oil and gas
reserves acquired since such year-end, which reserves were not reflected in such

calculated  in  accordance  with  Commission  guidelines  (utilizing  the prices
utilized in such year-end reserve  report),  and decreased by, as of the date of
determination,  the estimated  discounted future net revenues from (3) estimated
proved oil and gas reserves  produced or disposed of since such year-end and (4)
estimated oil and gas reserves  attributable to downward  revisions of estimates

Commission  guidelines  (utilizing the prices utilized in such year-end  reserve
report);  provided that, in the case of each of the determinations made pursuant

                                 THE SECURITIES

     Section 2.1 Amount of Securities; Issuable in Series.

     The aggregate  principal  amount of Securities  Outstanding at any one time
may not exceed  $225,000,000  except as  provided  in Section  2.7  hereof.  All
Securities  shall be  identical  in all  respects  other  than  issue  price and
issuance  dates.  The Securities may be issued in one or more series;  provided,
however,  that any Securities  issued with original  issue discount  ("OID") for
Federal  income tax  purposes  shall not be issued as part of the same series as
any Securities that are issued with a different  amount of OID or are not issued
with OID.

     Subject to Section  2.3,  the Trustee  shall  authenticate  Securities  for
original  issue  on  the  Issue  Date  in  the  aggregate  principal  amount  of
$150,000,000 (the "Original Securities").  With respect to any Securities issued
after the Issue Date (except for  Securities  authenticated  and delivered  upon
registration of transfer of, or in exchange for, or in lieu of, other Securities
pursuant to Section  2.7,  2.8,  2.9,  9.15,  9.16 or 10.6 or Appendix A), there
shall be  established  in or pursuant to a resolution  of the Board of Directors
and,  subject to Section 2.3, set forth or determined in the manner  provided in
an Officer's Certificate,  or established in one or more indentures supplemental
hereto, prior to the issuance of such Securities:


                                      E-165





     (1) whether  such  Securities  shall be issued as part of a new or existing
series of Securities and the title of such Securities  (which shall  distinguish
the Securities of the series from Securities of any other series);

     (2)  the  aggregate  principal  amount  of  such  Securities  which  may be
authenticated and delivered under this Indenture, which shall be in an aggregate
principal amount not to exceed $75,000,000 (except for Securities  authenticated
and delivered upon  registration  of transfer of, or in exchange for, or in lieu
of, other Securities of the same series pursuant to Section 2.7, 2.8, 2.9, 9.15,
9.16 or 10.6 or Appendix A and except for Securities which,  pursuant to Section
2.3, are deemed never to have been authenticated and delivered hereunder);

     (3) the issue price and issuance  date of such  Securities,  including  the
date from which interest on such Securities shall accrue;

     (4) if applicable,  that such  Securities  shall be issuable in whole or in
part  in the  form of one or more  Global  Securities  and,  in such  case,  the
respective  depositories for such Global  Securities,  the form of any legend or
legends  which shall be borne by any such  Global  Security in addition to or in
lieu of that set  forth in  Exhibit 1 to  Appendix  A and any  circumstances  in
addition  to or in lieu of those set forth in Section 2.3 of Appendix A in which
any such Global  Security may be  exchanged  in whole or in part for  Securities
registered,  and any transfer of such Global Security in whole or in part may be
registered,  in the name or names of Persons other than the  depository for such
Global Security or a nominee thereof; and

     (5) if applicable,  that such Securities shall not be issued in the form of
Initial  Securities  subject to  Appendix  A, but shall be issued in the form of
Exchange Securities as set forth in Exhibit A.

     If any of the terms of any series are  established by action taken pursuant
to a resolution of the Board of Directors,  a copy of an  appropriate  record of
such action shall be certified by the  Secretary or any  Assistant  Secretary of
the Company  and  delivered  to the  Trustee at or prior to the  delivery of the
Officers' Certificate or the trust indenture supplementary thereto setting forth
the terms of the series.

     Notwithstanding  anything to the  contrary in this  Section or otherwise in
this  Indenture,  any  additional  issuance of Securities  after the Issue Date,
whether such Securities are of the same or a different  series than the Original
Securities, shall be in a principal amount greater than or equal to $25,000,000.

         Section 2.2       Form and Dating.

         Provisions  relating to the Initial  Securities  of each series and the
Exchange Securities are set forth in Appendix A, which is hereby incorporated in
and  expressly  made a part of this  Indenture.  The Initial  Securities of each
series and the Trustee's certificate of authentication shall be substantially in
the  form of  Exhibit  1 to  Appendix  A which  is  hereby  incorporated  in and
expressly  made a part  of  this  Indenture.  The  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  of each  series  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  reasonably  acceptable to the Company.  Each Security
shall be dated the date of its  authentication.  The terms of the  Securities of
each  series set forth in Exhibit 1 to  Appendix A and Exhibit A are part of the
terms of this Indenture.


                                      E-166




     Section 2.3 Execution and Authentication.

     Two Officers of the Company  shall sign the  Securities  for the Company by
manual or facsimile  signature.  The Company's  seal may be impressed,  affixed,
imprinted or reproduced on the Securities and may be in facsimile form.

     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.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the  Company may deliver  Securities  of any series  executed by the
Company to the Trustee for authentication,  together with a written order of the
Company  signed  by two  Officers  of the  Company  for the  authentication  and
delivery of such  Securities,  and the Trustee in  accordance  with such written
order of the Company shall authenticate and deliver such Securities.

     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.

     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 as any  Registrar,  Paying Agent or agent for service of notices and
demands.

     Section 2.4 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 (the "Security  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.  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  5.6.  The
Company may act as Paying Agent, Registrar, co-registrar or transfer agent.

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

     Section 2.5 Paying Agent To Hold Money in Trust.

     Not later than 10:00 a.m.,  Eastern  standard time, on 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 Securityholders 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
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


                                      E-167





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 2.6 Securityholder 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
Securityholders.  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 Securityholders.

     Section 2.7 Replacement Securities.

     If a mutilated Security is surrendered to the Registrar or if the Holder of
a Security  claims that such  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.

     Every replacement Security is an additional obligation of the Company.

     Section 2.8 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  cancellation
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  2.7,  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, and the Paying
Agent is not prohibited  from paying such money to the  Securityholders  on that
date pursuant to the terms of this  Indenture,  then on and after that date such
Securities (or portions  thereof)  cease to be outstanding  and interest on them
ceases to accrue.

     Section 2.9 Temporary Securities.

     Until definitive Securities are ready for delivery, the Company may prepare
and the Trustee shall authenticate  temporary  Securities.  Temporary Securities
shall  be  substantially  in the  form of  definitive  Securities  but may  have
variations  that the Company  considers  appropriate  for temporary  Securities.
Without  unreasonable  delay,  the Company  shall  prepare and the Trustee shall
authenticate  definitive  Securities  and deliver them in exchange for temporary
Securities.



                                      E-168




     Section 2.10 Cancellation.

     The  Company  at  any  time  may  deliver  Securities  to the  Trustee  for
cancellation.  The  Registrar  and the Paying Agent shall forward to the Trustee
any Securities  surrendered to them for  registration  of transfer,  exchange or
payment.  The Trustee 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 cancellation and shall, upon
written request,  deliver a certificate of such destruction to the Company.  The
Company may not issue new Securities to replace Securities it has redeemed, paid
or delivered to the Trustee for cancellation.

     Section 2.11 Defaulted Interest.

     If the Company  defaults in a payment of  interest  on the  Securities,  it
shall pay the  defaulted  interest  in any  lawful  manner  plus,  to the extent
lawful,  interest  payable on the  defaulted  interest,  to the  persons who are
Securityholders  on a subsequent  special  record date, in each case at the rate
provided in the Securities  and in Section 9.1 hereof.  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
Securityholder  a notice that states the special  record date,  the payment date
and the amount of defaulted interest to be paid.

     Section 2.12 CUSIP Numbers.

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

                                  ARTICLE III.

                           SATISFACTION AND DISCHARGE

     Section 3.1 Satisfaction and Discharge of Indenture.

     This  Indenture  shall upon Company  Request cease to be of further  effect

Securities,  as expressly  provided for in this Indenture) as to all Outstanding
Securities,  and the Trustee, at the expense of the Company, shall, upon payment
of all  amounts  due the  Trustee  under  Section  5.6  hereof,  execute  proper

     obligations  of the type  described in clause (i) of the definition of Cash
     Equivalents  have  theretofore  been deposited in trust with the Trustee or
     any  Paying  Agent or  segregated  and held in  trust  by the  Company  and
     thereafter repaid to the Company or discharged from such trust, as provided
     in Section 9.3 hereof) have been delivered to the Trustee for cancellation,
     or

          (2) all such Securities not  theretofore  delivered to the Trustee for
     cancellation

               (i) have become due and payable, or


                                      E-169

          one year, or

               (iii) are to be  called  for  redemption  within  one year  under
          arrangements  satisfactory  to the Trustee for the giving of notice of
          redemption  by the  Trustee in the name,  and at the  expense,  of the
          Company,

     and the Company,  in the case of clause (2)(i),  (2)(ii) or (2)(iii) above,
     has irrevocably  deposited or caused to be deposited with the Trustee funds
     in an amount  sufficient to pay and discharge  the entire  indebtedness  on
     such Securities not theretofore  delivered to the Trustee for cancellation,
     for  principal  (and  premium,  if any)  and  interest  to the date of such
     deposit (in the case of Securities which have become due and payable) or to
     the Stated  Maturity or Redemption  Date, as the case may be, together with
     instructions  from the Company  irrevocably  directing the Trustee to apply
     such funds to the payment  thereof at maturity or  redemption,  as the case
     may be;

          (b) the  Company has paid or caused to be paid all other sums then due
     and payable hereunder by the Company; and

          (c) the Company has delivered to the Trustee an Officers'  Certificate
     and an Opinion of Counsel, which, taken together, state that all conditions
     precedent  herein  relating  to the  satisfaction  and  discharge  of  this
     Indenture have been complied with.

     Notwithstanding  the  satisfaction  and  discharge of this  Indenture,  the
obligations of the Company to the Trustee under Section 5.6 hereof and, if money
shall  have been  deposited  with the  Trustee  pursuant  to this  Section,  the
obligations  of the Trustee under  Section 3.2 hereof and the last  paragraph of
Section 9.3 hereof shall survive.

     Section 3.2 Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 9.3 hereof,  all
money deposited with the Trustee pursuant to Section 3.1 hereof shall be held in
trust and applied by it, in accordance with the provisions of the Securities and
this  Indenture,  to the  payment,  either  directly or through any Paying Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Persons entitled thereto,  of the principal (and premium,  if
any) and  interest  for whose  payment  such money has been  deposited  with the
Trustee.

                                   ARTICLE IV.

                                      E-171





Subsidiary of a petition or consent seeking  reorganization  or relief under any
applicable  federal or state law, or the consent by it under any such law to the
filing of any such petition or to the  appointment of or taking  possession by a
custodian,  receiver,  liquidator,  assignee,  trustee or sequestrator (or other
similar  official)  of the  Company  or any  Subsidiary  Guarantor  or any other
Restricted  Subsidiary or of any substantial part of its consolidated assets, or
the making by it of an  assignment  for the benefit of creditors  under any such

     Section 4.2 Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default (other than an Event of Default specified in Section
4.1(h) or (i) hereof)  occurs and is  continuing,  the Trustee or the Holders of
not  less  than  25%  in  aggregate  principal  amount  of the  Securities  then
Outstanding, by written notice to the Company (and to the Trustee if such notice
is given by the  Holders),  may, and the Trustee upon the request of the Holders
of not less than 25% in aggregate principal amount of the Outstanding Securities
shall, by a notice in writing to the Company,  declare all unpaid  principal of,
premium, if any, and accrued and unpaid interest on all the Securities to be due
and payable  immediately,  upon which declaration all amounts payable in respect
of the Securities  shall be immediately due and payable.  If an Event of Default
specified in Section 4.1(h) or (i) hereof occurs and is continuing,  the amounts
described  above shall  become and be  immediately  due and payable  without any
declaration, notice or other act on the part of the Trustee or any Holder.

     Promptly after the occurrence of a declaration of acceleration, the Company
shall notify each holder of Senior Indebtedness thereof, but failure to give any
such notice shall not affect such declaration or its consequences.

     At any time after a declaration of acceleration  has been made and before a
judgment or decree for payment of the money due has been obtained by the Trustee
as hereinafter in this Article provided,  the Holders of a majority in aggregate
principal  amount  of the  Securities  Outstanding,  by  written  notice  to the
Company,  the Subsidiary  Guarantors and the Trustee, may rescind and annul such
declaration and its consequences if

     (a) the Company or any Subsidiary  Guarantor has paid or deposited with the
Trustee a sum sufficient to pay,

          (1) all overdue interest on all Outstanding Securities,

          (2) all unpaid principal of (and premium,  if any, on) any Outstanding
     Securities  which have become due  otherwise  than by such  declaration  of
     acceleration, including any Securities required to have been purchased on a
     Change of Control Date or a Purchase  Date  pursuant to a Change of Control
     Offer or a Prepayment  Offer,  as  applicable,  and interest on such unpaid
     principal at the rate borne by the Securities,

          (3) to the extent that payment of such interest is lawful, interest on
     overdue interest and overdue  principal at the rate borne by the Securities
     (without  duplication  of any amount paid or deposited  pursuant to clauses
     (1) and (2) above), and

          (4) all  sums  paid  or  advanced  by the  Trustee  hereunder  and the
     reasonable  compensation,  expenses,  disbursements  and  advances  of  the
     Trustee, its agents and counsel;

     (b) the  rescission  would not  conflict  with any  judgment or decree of a
court of competent jurisdiction as  certified to the Trustee by the Company; and

                                      E-172





     (c) all  Events of  Default,  other  than the  non-payment  of  amounts  of
principal  of (or  premium,  if any,  on) or interest on  Securities  which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 4.13 hereof.

     No such rescission shall affect any subsequent  default or impair any right
consequent thereon.

     Notwithstanding the foregoing,  if an Event of Default specified in Section
4.1(e) hereof shall have occurred and be  continuing,  such Event of Default and
any  consequential   acceleration  shall  be  automatically   rescinded  if  the
Indebtedness that is the subject of such Event of Default has been repaid, or if
the  default  relating  to such  Indebtedness  is  waived  or cured  and if such
Indebtedness has been accelerated, then the holders thereof have rescinded their
declaration of acceleration in respect of such Indebtedness  (provided,  in each
case,  that such  repayment,  waiver,  cure or rescission  is effected  within a
period of 10 days from the  continuation  of such default  beyond the applicable
grace period or the occurrence of such acceleration), and written notice of such
repayment, or cure or waiver and rescission, as the case may be, shall have been
given to the  Trustee by the Company  and  countersigned  by the holders of such
Indebtedness or a trustee, fiduciary or agent for such holders or other evidence
satisfactory to the Trustee of such events is provided to the Trustee, within 30
days after any such  acceleration in respect of the  Securities,  and so long as
such  rescission of any such  acceleration  of the Securities  does not conflict
with any judgment or decree as certified to the Trustee by the Company.

     Section  4.3  Collection  of  Indebtedness  and  Suits for  Enforcement  by
Trustee.

     The Company covenants that if

     (a)  default is made in the payment of any  installment  of interest on any
Security when such interest  becomes due and payable and such default  continues
for a period of 30 days, or

     (b) default is made in the payment of the principal of (or premium, if any,
on) any  Security  at the  Maturity  thereof  or with  respect  to any  Security
required to have been purchased by the Company on the Change of Control Purchase
Date or the Purchase  Date  pursuant to a Change of Control  Offer or Prepayment
Offer, as applicable,  then the Company will, upon demand of the Trustee, pay to
the Trustee for the benefit of the Holders of such Securities,  the whole amount
then due and payable on such Securities for principal (and premium,  if any) and
interest,  and interest on any overdue  principal (and premium,  if any) and, to
the extent that payment of such interest shall be legally enforceable,  upon any
overdue  installment of interest,  at the rate borne by the Securities,  and, in
addition thereto,  such further amount as shall be sufficient to cover the costs
and expenses of  collection,  including the reasonable  compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel.

     If the Company fails to pay such amounts  forthwith  upon such demand,  the
Trustee,  in its own name as  trustee  of an  express  trust,  may  institute  a
judicial  proceeding  for the  collection  of the  sums so due and  unpaid,  may
prosecute  such  proceeding to judgment or final decree and may enforce the same
against the Company or any other  obligor  upon the  Securities  and collect the
money adjudged or decreed to be payable in the manner provided by law out of the
Property  of the  Company or any other  obligor  upon the  Securities,  wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion  proceed  to  protect  and  enforce  its rights and the rights of the
Holders by such appropriate  judicial proceedings as the Trustee shall deem most
effectual  to protect  and  enforce any such  rights,  whether for the  specific
enforcement  of any  covenant or  agreement  in this  Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.


                                      E-173





     Section 4.4 Trustee May File Proofs of Claim.

     In case  of the  pendency  of any  receivership,  insolvency,  liquidation,
bankruptcy,  reorganization,   arrangement,  adjustment,  composition  or  other
judicial  proceeding  relative to the Company,  any Subsidiary  Guarantor or any
other  obligor  upon the  Securities,  their  creditors  or the  Property of the
Company,  any  Subsidiary  Guarantor  or of  such  other  obligor,  the  Trustee
(irrespective  of whether the principal of the Securities  shall then be due and
payable as therein  expressed or by declaration or otherwise and irrespective of
whether the Trustee  shall have made any demand on the Company,  the  Subsidiary
Guarantors or such other obligor for the payment of overdue principal,  premium,
if any, or interest)  shall be entitled and empowered,  by  intervention in such
proceeding or otherwise,

     (a) to file and  prove a claim  for the  whole  amount  of  principal  (and
premium,  if any) and interest owing and unpaid in respect of the Securities and
to file such other  papers or  documents  and take any other  actions  including
participation  as a full  member of any  creditor or other  committee  as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation,  expenses,  disbursements and advances of
the Trustee, its agents and counsel) and of the Holders allowed in such judicial
proceeding, and

     (b) to  collect  and  receive  any  money  or  other  Property  payable  or
deliverable on any such claims and to distribute the same;

and any custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator or
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder to make such  payments to the Trustee  and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee  any  amount  due  to it  for  the  reasonable  compensation,  expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 5.6 hereof.

     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  Subsidiary  Guarantees  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 4.5 Trustee May Enforce Claims Without Possession of Securities.

     All rights of action and claims under this  Indenture or the  Securities or
the Subsidiary  Guarantees may be prosecuted and enforced by the Trustee without
the  possession  of any of the  Securities  or  the  production  thereof  in any
proceeding relating thereto,  and any such proceeding  instituted by the Trustee
shall be brought in its own name and as  trustee  of an express  trust,  and any
recovery of judgment  shall,  after  provision for the payment of the reasonable
compensation,  expenses,  disbursements and advances of the Trustee,  its agents
and  counsel,  be for the ratable  benefit of the Holders of the  Securities  in
respect of which such judgment has been recovered.


     Section 4.6 Application of Money Collected.

     Any money  collected  by the  Trustee  pursuant  to this  Article  shall be
applied in the following  order,  at the date or dates fixed by the Trustee and,
in the case of the  distribution  of such  money on  account  of  principal  (or
premium,  if any) or  interest,  upon  presentation  of the  Securities  and the
notation  thereon  of the  payment  if only  partially  paid and upon  surrender
thereof if fully paid:

          FIRST: to the payment of all amounts due the Trustee under Section 5.6
     hereof;


                                      E-174





          SECOND:  to the  payment  of the  amounts  then  due  and  unpaid  for
     principal of (and  premium,  if any, on) and interest on the  Securities in

     ratably,  without  preference  or  priority of any kind,  according  to the
     amounts due and payable on such  Securities for principal (and premium,  if
     any) and interest, respectively; and

          THIRD:  the balance,  if any, to the Company,  or to whomsoever may be
     lawfully  entitled  to  receive  the  same,  or  as a  court  of  competent
     jurisdiction may direct.

     Section 4.7 Limitation on Suits.

     No  Holder  of any  Securities  shall  have  any  right  to  institute  any
proceeding,  judicial or otherwise,  with respect to this Indenture,  or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless:

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

     (b) the Holders of not less than 25% in aggregate  principal  amount of the
Outstanding  Securities  shall  have made  written  request  to the  Trustee  to
institute  proceedings  in  respect  of such Event of Default in its own name as
Trustee hereunder;

     (c) such  Holder or Holders  have  offered to the Trustee  such  reasonable
indemnity as it may require  against the costs,  expenses and  liabilities to be
incurred in compliance with such request;

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

     (e) no direction  inconsistent  with such written request has been given to
the Trustee  during  such 60-day  period by the Holders of a majority or more in
aggregate principal amount of the Outstanding Securities;

it being  understood  and intended  that no one or more  Holders  shall have any
right in any manner  whatever by virtue of, or by availing of, any  provision of
this Indenture to affect,  disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain  priority or preference over any other Holders
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided and for the equal and ratable benefit of all the Holders.

      Section 4.8   Unconditional  Right of Holders to Receive Principal,
                    Premium and Interest.

     Notwithstanding  any other provision in this  Indenture,  the Holder of any

such  Security of the  principal  of (and  premium if any,  on) and  (subject to
Section  2.11  hereof)  interest  on,  such  Security on the  respective  Stated
Maturities  expressed in such  Security (or, in the case of  redemption,  on the
Redemption  Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

     Section 4.9 Restoration of Rights and Remedies.

     If the Trustee or any Holder has  instituted  any proceeding to enforce any
right or remedy under this Indenture and such  proceeding has been  discontinued
or abandoned for any reason, or has been determined  adversely to the Trustee or
to such Holder,  then and in every such case,  subject to any  determination  in
such proceeding,  the Company,  the Subsidiary  Guarantors,  the Trustee and the
Holders shall be restored  severally and  respectively to their former positions
hereunder  and  thereunder  and all rights and  remedies  of the Trustee and the
Holders shall continue as though no such proceeding had been instituted.

     Section 4.10 Rights and Remedies Cumulative.

     Except as otherwise  provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section
2.7 hereof,  no right or remedy herein conferred upon or reserved to the Trustee

every right and remedy shall, to the extent  permitted by law, be cumulative and
in addition to every other right and remedy given  hereunder or now or hereafter
existing at law or in equity or  otherwise.  The  assertion or employment of any
right or remedy  hereunder,  or  otherwise,  shall not  prevent  the  concurrent
assertion or employment of any other appropriate right or remedy.

     Section 4.11 Delay or Omission Not Waiver.

     No delay or  omission  of the  Trustee or of any Holder of any  Security to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or  constitute  a waiver of any such Event of Default or an
acquiescence therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised  from time to time,  and as often
as may be deemed  expedient,  by the Trustee or by the Holders,  as the case may
be.

     Section 4.12 Control by Holders.

     The Holders of not less than a majority in  aggregate  principal  amount of
the Outstanding  Securities shall 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 the Trustee, provided that

     (a) such  direction  shall not be in conflict  with any rule of law or with
this Indenture,

     (b) the  Trustee  may take any other  action  deemed  proper by the Trustee
which is not inconsistent with such direction, and

     (c) the Trustee need not take any action which might involve it in personal
liability  or expense  for which the  Trustee  has not  received a  satisfactory
indemnity therefor or be unduly prejudicial to the Holders not joining therein.

     Section 4.13 Waiver of Past Defaults.

     The Holders of not less than a majority in  aggregate  principal  amount of
the  Outstanding  Securities  may on behalf of the Holders of all the Securities
waive any existing Default or Event of Default  hereunder and its  consequences,
except a Default or Event of Default

     (a) in respect of the payment of the principal of (or premium,  if any, on)
or interest on any Security, or


                                      E-176





     (b) in respect of a covenant or provision  hereof which under  Article VIII
hereof  cannot be modified or amended  without the consent of the Holder of each
Outstanding Security affected thereby.

     Upon any such waiver, such Default or Event of Default shall cease to exist
for every purpose under this  Indenture,  but no such waiver shall extend to any
subsequent  or other  fault or Event of Default  or impair any right  consequent
thereon.

     Section 4.14 Waiver of Stay, Extension or Usury Laws.

     Each of the Company and the Subsidiary  Guarantors 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  wherever  enacted,  now or at any time
hereafter  in  force,  which  would  prohibit  or  forgive  the  Company  or any
Subsidiary  Guarantor  from  paying  all or any  portion  of  the  principal  of
(premium,  if any, on) or interest on the Securities as contemplated  herein, 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
covenant  that they 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.

                                   ARTICLE V.

                                   THE TRUSTEE

     Section 5.1 Duties of Trustee.

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

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

          (i) the Trustee undertakes to perform such duties and only such duties
     as are specifically set forth in this Indenture and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (ii)  in the  absence  of bad  faith  on its  part,  the  Trustee  may
     conclusively  rely, and shall be fully  protected in so relying,  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;  provided, however, that,
     in the case of any such  certificates  or opinions  which by any  provision
     hereof are  specifically  required  to be  furnished  to the  Trustee,  the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture, but the Trustee has
     no obligation to determine the accuracy or  completeness  (other than as to
     conformity with the  requirements of this Indenture) of the statements made
     therein.

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

          (i) this paragraph shall not limit the effect of Section 5.1(b);


                                      E-177





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

          (iii) the Trustee  shall not be liable  with  respect to any action it
     takes  or  omits  to take in good  faith  in  accordance  with a  direction
     received by it pursuant to Section 4.12.

     Section 5.2 Certain Rights of Trustee.

     Subject to the provisions of Section 5.1 hereof:

     (a) the Trustee may  conclusively  rely and shall be protected in acting or
refraining from acting upon any resolution,  certificate, statement, instrument,
opinion,  report, notice, request,  direction,  consent, order, bond, debenture,
note,  other evidence of indebtedness or other paper (whether in its original or
facsimile  form),  or  document  believed  by it to be genuine  and to have been
signed or presented by the proper party or parties;

     (b) any request or  direction  of the  Company  mentioned  herein  shall be
sufficiently  evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

it desirable that a matter be proved or established  prior to taking,  suffering
or omitting any action  hereunder,  the Trustee (unless other evidence be herein
specifically prescribed) may, in the absence of bad faith on its part, rely upon
an Officers' Certificate;

     (d) the Trustee may consult  with counsel 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 in reliance thereon;

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

     (f) 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,

omitted by it in good faith and believed by it in good faith to be authorized or
within the discretion or rights or powers  conferred upon it by this  Indenture;
and

     (i) the  Trustee  shall not be deemed to have  notice or  knowledge  of any
matter  unless a  Responsible  Officer  has actual  knowledge  thereof or unless


                                      E-178





written notice thereof is received by the Trustee at its Corporate  Trust Office
and such  notice  references  the  Securities  generally,  the  Company  or this
Indenture.

     The Trustee shall not be required to advance,  expend or risk its own funds
or otherwise  incur any  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 for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

     Section 5.3 Trustee Not Responsible for Recitals or Issuance of Securities.

     The  recitals  contained  herein  and in the  Securities,  except  for  the
Trustee's  certificates of  authentication,  shall be taken as the statements of
the Company or the  Subsidiary  Guarantors,  as the case may be, and the Trustee
assumes  no  responsibility  for  their   correctness.   The  Trustee  makes  no
representations  as to the  validity  or  sufficiency  of  this  Indenture,  the

for the use or  application  by the Company of any  Securities  or the  proceeds
thereof.

TIA Sections 310(b) and 311 in the case of the Trustee,  may otherwise deal with
the Company and the Subsidiary  Guarantors with the same rights it would have if
it were not the Trustee, Paying Agent, Registrar or such other agent.

     Section 5.5 Money Held in Trust.

     Money held by the Trustee in trust  hereunder  need not be segregated  from
other funds except to the extent  required by law. The Trustee shall be under no

     The Company agrees:

     (a) to pay to the  Trustee  from  time to  time  such  compensation  as the
Company and the Trustee  may agree in writing  for all  services  rendered by it
hereunder  (which  compensation  shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust);

     (b) except as otherwise expressly provided herein, to reimburse the Trustee
upon  its  request  for all  reasonable  expenses,  disbursements  and  advances
incurred  or made by the  Trustee  in  accordance  with  any  provision  of this
Indenture  (including the compensation and the expenses and disbursements of its
agents and counsel), except any such expense,  disbursement or advance as may be
attributable to the Trustee's wilful misconduct, negligence or bad faith; and

     (c) to  indemnify  the Trustee for,  and to hold it harmless  against,  any
loss,  liability,  claim damage or expense incurred without wilful misconduct or

condition at least annually,  pursuant to law or to the requirements of federal,
state,  territorial or District of Columbia  supervising or examining authority,
then for the purposes of this  Section 5.7, the combined  capital and surplus of
such  corporation  shall be deemed to be its combined capital and surplus as set
forth in its most recent  report of condition so  published.  If at any time the
Trustee  shall cease to be eligible in  accordance  with the  provisions of this

     Section 5.9 Resignation and Removal; Appointment of Successor.

     (a) No  resignation  or  removal of the  Trustee  and no  appointment  of a
successor  Trustee  pursuant to this Article  shall become  effective  until the
acceptance  of  appointment  by the  successor  Trustee in  accordance  with the
applicable requirements of Section 5.10 hereof.

     (b) The Trustee may resign at any time by giving  written notice thereof to
the Company.  If the instrument of acceptance by a successor Trustee required by

less  than  a  majority  in  aggregate   principal  amount  of  the  Outstanding
Securities, delivered to the Trustee and to the Company.

     (d) If at any time:

          (1) the  Trustee  shall  fail to  comply  with the  provisions  of TIA
     Section  310(b)  after  written  request  therefor by the Company or by any
     Holder  who has been a bona  fide  Holder  of a  Security  for at least six
     months, or


                                      E-180





          (2) the Trustee  shall cease to be eligible  under  Section 5.7 hereof
     and shall fail to resign after written  request  therefor by the Company or
     by any  Holder who has been a bona fide  Holder of a Security  for at least
     six months, or

          (3) the Trustee shall become  incapable of acting or shall be adjudged
     a bankrupt or  insolvent  or a receiver  of the Trustee or of its  property
     shall be  appointed or any public  officer  shall take charge or control of
     the   Trustee  or  of  its   property   or  affairs   for  the  purpose  of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company,  by a Board Resolution,  may remove the
Trustee,  or (ii) subject to TIA Section 315(e),  any Holder who has been a bona
fide Holder of a Security  for at least six months may, on behalf of himself and
all others similarly situated,  petition any court of competent jurisdiction for

one year after such resignation,  removal or incapability,  or the occurrence of
such vacancy,  a successor Trustee shall be appointed by Act of the Holders of a
majority in aggregate principal amount of the Outstanding  Securities  delivered
to the Company and the  retiring  Trustee,  the  successor  Trustee so appointed
shall,  forthwith upon its acceptance of such appointment,  become the successor
Trustee and  supersede  the successor  Trustee  appointed by the Company.  If no
successor Trustee shall have been so appointed by the Company or the Holders and
accepted appointment in the manner hereinafter provided, the retiring Trustee or
any Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated,  petition any court
of  competent  jurisdiction  for the  appointment  of a successor  Trustee.  The
evidence of such successorship may, but need not be, evidenced by a supplemental
indenture.

     (f) The Company shall give notice of each  resignation  and each removal of
the  Trustee  and each  appointment  of a  successor  Trustee to the  Holders of
Securities in the manner provided for in Section 13.5 hereof.  Each notice shall
include the name of the successor Trustee and the address of its Corporate Trust
Office.

5.9, the Company's  obligations under Section 5.6 shall continue for the benefit
of the retiring Trustee.

     Section 5.10 Acceptance of Appointment by Successor.

     Every successor Trustee appointed hereunder shall execute,  acknowledge and
deliver to the Company and to the retiring Trustee an instrument  accepting such
appointment,  and thereupon the  resignation or removal of the retiring  Trustee
shall become effective and such successor Trustee, without any further act, deed
or  conveyance,  shall  become  vested with all the rights,  powers,  trusts and
duties of the retiring Trustee;  but, on request of the Company or the successor
Trustee,  such retiring Trustee shall,  upon payment of all amounts due it under
Section 5.6  hereof,  execute and  deliver an  instrument  transferring  to such
successor Trustee all the rights,  powers and trusts of the retiring Trustee and
shall duly assign,  transfer and deliver to such successor Trustee all money and
other Property held by such retiring Trustee hereunder. Upon request of any such
successor  Trustee,  the Company shall execute any and all  instruments for more
fully and certainly vesting in and confirming to such successor Trustee all such
rights, powers and trusts.

     No successor  Trustee  shall accept its  appointment  unless at the time of

banking  association  shall be  otherwise  qualified  and  eligible  under  this
Article,  without the execution or filing of any paper or any further act on the
part of any of the  parties  hereto.  In case any  Securities  shall  have  been
authenticated,  but not delivered,  by the Trustee then in office, any successor
by merger,  conversion or consolidation to such authenticating Trustee may adopt
such  authentication  and deliver the Securities so authenticated  with the same
effect as if such successor  Trustee had itself  authenticated  such Securities;
and  in  case  at  that  time  any  of  the  Securities   shall  not  have  been
authenticated,  any successor Trustee may authenticate such Securities either in

consolidation.

have been  cured or waived;  provided,  however,  that,  except in the case of a
Default in the payment of the principal of (or premium,  if any, on) or interest
on any Security,  the Trustee shall be protected in  withholding  such notice if
and so long as the  board  of  directors,  the  executive  committee  or a trust
committee of directors and/or Responsible  Officers of the Trustee in good faith
determines  that  the  withholding  of such  notice  is in the  interest  of the
Holders.  The Trustee  shall not be deemed to have notice of any Default,  other
than a Default  under 4.1(a) or (b),  unless the Trustee shall have been advised
in writing that a Default has occurred. No duty imposed upon the Trustee in this
Indenture  shall be applicable  with respect to any Default of which the Trustee
is not deemed to have notice.

new Securities so modified as to conform,  in the opinion of the Trustee and the
Company, to any such supplemental  indenture may be prepared and executed by the
Company,  and  authenticated  and  delivered  by the  Trustee  in  exchange  for
Outstanding Securities.

     Section 8.7 Notice of Supplemental Indentures.

     Promptly  after  the  execution  by the  Company  and  the  Trustee  of any
supplemental  indenture  pursuant to the  provisions of Section 8.2 hereof,  the
Company shall give notice  thereof to the Holders of each  Outstanding  Security
affected,  in the manner  provided for in Section 13.5 hereof,  setting forth in
general terms the substance of such supplemental indenture.

                                   ARTICLE IX.

                                    COVENANTS

     Section 9.1 Payment of Principal, Premium, if any, and Interest.

     The Company  covenants  and agrees for the  benefit of the Holders  that it
will duly and  punctually  pay the  principal of (and  premium,  if any, on) and
interest on the  Securities in accordance  with the terms of the  Securities and
this Indenture.

     Section 9.2 Maintenance of Office or Agency.

     The Company  shall  maintain an office or agency  where  Securities  may be
presented or surrendered  for payment,  where  Securities may be surrendered for
registration  of transfer or exchange  and where  notices and demands to or upon
the Company in respect of the  Securities,  the  Subsidiary  Guarantees and this
Indenture may be served. The New York office of the Trustee shall be such office
or agency of the Company,  unless the Company shall  designate and maintain some
other office or agency for one or more of such  purposes.  The Company will give
prompt  written  notice to the Trustee of any change in the location of any such
office or agency.  If at any time the Company  shall fail to  maintain  any such


                                      E-187




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  aforementioned  office of the  Trustee,  and the  Company  hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

     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 any such  designation.  Further,
if at any time there  shall be no such  office or agency in The City of New York
where the Securities may be presented or  surrendered  for payment,  the Company
shall  forthwith  designate and maintain such an office or agency in The City of
New York, in order that the Securities shall at all times be payable in The City
of New York.  The Company will give prompt  written notice to the Trustee of any
such  designation or rescission and any change in the location of any such other
office or agency.

     Section 9.3 Money for Security Payments to Be Held in Trust.

     If the Company shall at any time act as its own Paying Agent,  it shall, on
or before 10:00 a.m.,  Eastern  time,  on each due date of the principal of (and
premium, if any, on) or interest on any of the Securities, segregate and hold in
trust for the benefit of the Persons  entitled  thereto a sum  sufficient to pay
the principal  (and premium,  if any) or interest so becoming due until such sum
shall be paid to such  Persons or otherwise  disposed of as herein  provided and
will promptly notify the Trustee of its action or failure so to act.

     Whenever  the  Company  shall  have  one or  more  Paying  Agents  for  the
Securities,  it will on or before 10:00 a.m.,  Eastern time, on each due date of
the  principal of (and  premium,  if any,  on), or interest on, any  Securities,
deposit with a Paying Agent  immediately  available funds in a sum sufficient to
pay the principal (and premium,  if any) or interest so becoming due, such funds
to be held in trust for the benefit of the Persons  entitled to such  principal,
premium or  interest,  and (unless such Paying Agent is the Trustee) the Company
shall promptly notify the Trustee of such action or any failure so to act.

     The  Company  shall  cause each Paying  Agent  (other than the  Trustee) to
execute  and  deliver to the Trustee an  instrument  in which such Paying  Agent
shall agree with the Trustee,  subject to the  provisions of this Section,  that
such Paying Agent will:

     (a) hold all  sums  held by it for the  payment  of the  principal  of (and
premium,  if any, on) or interest on  Securities in trust for the benefit of the
Persons  entitled  thereto  until  such sums  shall be paid to such  Persons  or
otherwise disposed of as herein provided;

     (b) give the  Trustee  notice of any  default by the  Company (or any other
obligor  upon the  Securities)  in the making of any payment of  principal  (and
premium, if any) or interest; and

     (c) at any  time  during  the  continuance  of any such  default,  upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  liability  with respect to such
sums. The Trustee and each Paying Agent shall promptly pay to the Company,  upon
Company  Request,  any money held by them (other than pursuant to Article XI) at
any time in excess of amounts  required to pay  principal,  premium,  if any, or
interest on the Securities.


                                      E-188





     Subject to  applicable  escheat  and  abandoned  property  laws,  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 (and premium,  if any, on) or interest
on any Security and remaining  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 Company Request, or (if then held by the Company) shall be discharged
from  such  trust;  and the  Holder of such  Security  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.

     Section 9.4 Corporate Existence.

     Except as expressly permitted by Article VII hereof, Section 9.16 hereof or
other provisions of this Indenture, the Company shall do or cause to be done all
things  necessary  to preserve  and keep in full force and effect the  corporate
existence, rights (charter and statutory) and franchises of the Company and each
Restricted Subsidiary; provided, however, that the Company shall not be required
to  preserve  any such  existence  of its  Restricted  Subsidiaries,  rights  or
franchises,  if the Board of Directors of the Company shall  determine  that the
preservation  thereof is no longer  desirable  in the conduct of the business of
the Company and its Restricted Subsidiaries, taken as a whole, and that the loss
thereof is not disadvantageous in any material respect to the Holders.

     Section 9.5 Payment of Taxes; Maintenance of Properties; Insurance.

     The  Company  shall  pay or  discharge  or cause to be paid or  discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental  charges  levied or  imposed  upon the  Company  or any  Restricted
Subsidiary  or upon the  income,  profits  or  Property  of the  Company  or any
Restricted  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 Restricted 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  and  for  which
appropriate provision has been made in accordance with GAAP.

     The Company shall cause all material Properties owned by the Company or any
Restricted Subsidiary and used or held for use in the conduct of its business or
the business of any  Restricted  Subsidiary  to be  maintained  and kept in good
condition, repair and working order (ordinary wear and tear excepted), all as in
the judgment of the Company or such  Restricted  Subsidiary  may be necessary so
that its  business may be properly  and  advantageously  conducted at all times;
provided, however, that nothing in this Section shall prevent the Company or any
Restricted  Subsidiary  from  discontinuing  the  maintenance  of  any  of  such
Properties  if such  discontinuance  is, in the  judgment of the Company or such
Restricted  Subsidiary,  as the case may be,  desirable  in the  conduct  of the
business of the Company or such Restricted Subsidiary and not disadvantageous in
any material  respect to the Holders.  Notwithstanding  the  foregoing,  nothing
contained  in this Section 9.5 shall limit or impair in any way the right of the
Company and its Restricted  Subsidiaries to sell, divest and otherwise to engage
in transactions that are otherwise permitted by this Indenture.

     The Company  shall at all times keep all of its,  and cause its  Restricted
Subsidiaries to keep their,  Properties which are of an insurable nature insured
with insurers, believed by the Company to be responsible, against loss or damage
to the extent that property of similar  character  and in a similar  location is
usually  so  insured  by  corporations   similarly   situated  and  owning  like
Properties.

     The  Company  or any  Restricted  Subsidiary  may adopt  such other plan or
method of  protection,  in lieu of or  supplemental  to insurance with insurers,
whether  by the  establishment  of an  insurance  fund or reserve to be held and
applied to make good losses from  casualties,  or  otherwise,  conforming to the


                                      E-189





systems of self-insurance maintained by corporations similarly situated and in a
similar location and owning like  Properties,  as may be determined by the Board
of Directors of the Company or such Restricted Subsidiary.

     Section 9.6 Limitation on Conduct of Business.

     The  Company  shall  not,  and  shall  not  permit  any of  its  Restricted
Subsidiaries  to,  engage in the conduct of any business  other than the Oil and
Gas Business.

     Section 9.7 Statement by Officers as to Default.

     (a) The Company shall deliver to the Trustee, within 100 days after the end
of each  fiscal year of the Company and within 45 days of the end of each of the
first,  second  and  third  quarters  of each  fiscal  year of the  Company,  an
Officers' Certificate stating that a review of the activities of the Company and
its Restricted  Subsidiaries during the preceding fiscal quarter or fiscal year,
as applicable,  has been made under the supervision of the signing Officers with
a view to  determining  whether the Company has kept,  observed,  performed  and
fulfilled its obligations under this Indenture,  and further stating, as to each
such  Officer  signing  such  certificate,  that to the  best of such  Officer's
knowledge the Company has kept, observed, performed and fulfilled each and every
condition  and covenant  contained in this  Indenture and no Default or Event of
Default has  occurred  and is  continuing  (or, if a Default or Event of Default
shall have  occurred to either such  Officer's  knowledge,  describing  all such
Defaults or Events of Default of which such Officer may have  knowledge and what
action the  Company is taking or proposes to take with  respect  thereto).  Such
Officers'  Certificate shall comply with TIA Section 314(a)(4).  For purposes of
this Section 9.7(a),  such compliance shall be determined  without regard to any
period of grace or requirement of notice under this Indenture.

     (b) The Company  shall,  so long as any of the  Securities is  outstanding,
deliver to the Trustee,  upon any of its Officers  becoming aware of any Default
or Event of Default, an Officers'  Certificate  specifying such Default or Event
of Default and what action the Company  proposes to take with  respect  thereto,
within 10 days of its occurrence.

     Section 9.8 Provision of Financial Information.

     The Company (and the Subsidiary Guarantors,  if applicable) shall file on a
timely  basis with the SEC,  to the extent  such  filings  are  accepted  by the
Commission  and whether or not the Company has a class of securities  registered
under  the  Exchange  Act,  the  annual  reports,  quarterly  reports  and other
documents  that the  Company  would be  required  to file if it were  subject to
Section  13  or 15  of  the  Exchange  Act.  The  Company  (and  the  Subsidiary
Guarantors, if applicable) shall also file with the Trustee (with exhibits), and
provide to each Holder of Securities  (without  exhibits),  without cost to such
Holder,  copies of such reports and  documents  within 15 days after the date on
which the Company  (and the  Subsidiary  Guarantors,  if  applicable)  file such
reports and documents  with the Commission or the date on which the Company (and
the Subsidiary Guarantors, if applicable) would be required to file such reports
and  documents if the Company  were so required  and, if filing such reports and
documents with the Commission is not accepted by the Commission or is prohibited
under the  Exchange  Act,  the Company  shall  supply at its cost copies of such
reports  and  documents  (including  any  exhibits  thereto)  to any  Holder  of
Securities  promptly upon written  request given in accordance with Section 13.4
hereof. The Company is obligated to make available,  upon request, to any Holder
of Securities the information  required by Rule 144A(d)(4)  under the Securities
Act,  during  any period in which the  Company  is not  subject to Section 13 or
15(d) of the Exchange Act.

         (other than to a Restricted Subsidiary) of Subordinated Indebtedness of
         the  Company  so  long  as  (A)  the  principal   amount  of  such  new
         Indebtedness  does  not  exceed  the  principal  amount  (or,  if  such
         Subordinated  Indebtedness being refinanced provides for an amount less
         than  the  principal  amount  thereof  to be  due  and  payable  upon a
         declaration of acceleration  thereof, such lesser amount as of the date
         of determination) of the Subordinated  Indebtedness being so purchased,
         redeemed, repaid, defeased, acquired or retired, plus the amount of any
         premium  required  to be  paid  in  connection  with  such  refinancing
         pursuant to the terms of the  Indebtedness  refinanced or the amount of
         any  premium  reasonably  determined  by the  Company as  necessary  to
         accomplish such refinancing, plus the amount of expenses of the Company
         incurred in connection with such refinancing, (B) such new Indebtedness
         is  subordinated  to the Securities at least to the same extent as such


                                      E-192





          Subordinated  Indebtedness so purchased,  redeemed,  repaid, defeased,
          acquired or retired, and (C) such new Indebtedness has an Average Life
          to Stated  Maturity  that is longer  than the  Average  Life to Stated
          Maturity  of the  Securities  and such new  Indebtedness  has a Stated
          Maturity for its final scheduled principal payment that is at least 91
          days later than the Stated Maturity for the final scheduled  principal
          payment of the Securities; and

                  (vi) loans made to  officers,  directors  or  employees of the
         Company or any Restricted Subsidiary approved by the Board of Directors
         of  the  Company  in an  aggregate  amount  not  to  exceed  $1,000,000
         outstanding  at any one time, the proceeds of which are used solely (A)
         to purchase common stock of the Company in connection with a restricted
         stock or employee  stock  purchase  plan, or to exercise  stock options
         received pursuant to an employee or director stock option plan or other
         incentive plan, in a principal  amount not to exceed the exercise price
         of such stock options or (B) to refinance loans,  together with accrued
         interest thereon, made pursuant to item (A) of this clause (v).

          The actions  described in clauses (i), (ii),  (iii),  (iv) and (vi) of
this  paragraph (b) shall be  Restricted  Payments that shall be permitted to be
made in  accordance  with this  paragraph  (b) but shall  reduce the amount that
would  otherwise  be  available  for  Restricted  Payments  under  clause (3) of
paragraph  (a)  (provided  that any dividend paid pursuant to clause (i) of this
paragraph  (b) shall reduce the amount that would  otherwise be available  under
clause (3) of paragraph (a) when declared,  but not also when  subsequently paid
pursuant to such clause (i)),  and the actions  described in clause (iv) of this
paragraph (b) shall be permitted to be taken in accordance  with this  paragraph
and shall not reduce the amount that would otherwise be available for Restricted
Payments under clause (3) of paragraph (a).

     (c) In computing Consolidated Net Income under paragraph (a) above, (1) the
Company shall use audited financial  statements for the portions of the relevant
period for which  audited  financial  statements  are  available  on the date of
determination  and unaudited  financial  statements and other current  financial
data based on the books and records of the Company for the remaining  portion of
such period and (2) the Company  shall be permitted to rely in good faith on the
financial statements and other financial data derived from the books and records
of the Company that are available on the date of  determination.  If the Company
makes a Restricted  Payment which,  at the time of the making of such Restricted
Payment would in the good faith  determination of the Company be permitted under
the requirements of this Indenture,  such Restricted  Payment shall be deemed to
have been made in compliance with this Indenture  notwithstanding any subsequent
adjustments made in good faith to the Company's financial  statements  affecting
Consolidated Net Income of the Company for any period.

     Section 9.10 Limitation on Guarantees by Subsidiary Guarantors.

         The Company shall not permit any Subsidiary  Guarantor to guarantee the
payment of any  Subordinated  Indebtedness  of the Company unless such guarantee
shall be  subordinated to such Subsidiary  Guarantor's  Subsidiary  Guarantee at
least to the same extent as such  Subordinated  Indebtedness  is subordinated to
the  Securities;  provided,  however,  that  this  Section  9.10  shall  not  be
applicable to any guarantee of any Subsidiary  Guarantor that (i) existed at the
time such Person became a Subsidiary of the Company and (ii) was not incurred in
connection with, or in contemplation  of, such Person's becoming a Subsidiary of
the Company.

     Section 9.11 Limitation on Indebtedness and Disqualified Capital Stock.

     (a) The  Company  shall not,  and shall not  permit  any of its  Restricted
Subsidiaries  to,  create,  incur,  assume,  guarantee  or in any manner  become
directly or  indirectly  liable for the payment of  (collectively,  "incur") any
Indebtedness  (including  any  Acquired  Indebtedness),   except  for  Permitted
Indebtedness,  and the  Company  shall  not,  and  shall not  permit  any of its


                                      E-193




Restricted Subsidiaries to, issue any Disqualified Capital Stock (except for the
issuance by the Company of (A) 1,948,001  shares of Series A Preferred Stock and
1,051,999  shares of Series B Preferred Stock on the date of this Indenture (and
including the shares of Series A Preferred  Stock issued upon the  conversion of
such shares of Series B Preferred  Stock into shares of Series A Preferred Stock
in accordance with their terms) and (B) Disqualified  Capital Stock (1) which is
redeemable  at the Company's  option in cash or Qualified  Capital Stock and (2)
the dividends on which are payable at the Company's  option in cash or Qualified
Capital  Stock);   provided  however,   that  the  Company  and  its  Restricted
Subsidiaries  that are  Subsidiary  Guarantors may incur  Indebtedness  or issue
shares of Disqualified  Capital Stock if (i) at the time of such event and after
giving  effect  thereto  on a pro forma  basis  the  Consolidated  Fixed  Charge
Coverage  Ratio for the four full  quarters  immediately  preceding  such event,
taken as one  period,  would have been  equal to or greater  than 2.5 to 1.0 and
(ii) no Default or Event of Default shall have occurred and be continuing at the
time such additional Indebtedness is incurred or such Disqualified Capital Stock
is issued or would occur as a consequence  of the  incurrence of the  additional
Indebtedness or the issuance of the Disqualified  Capital Stock. For purposes of
determining  compliance with this Section 9.11(a),  in the event that an item of
Indebtedness  meets the criteria of one or more of the  categories  of Permitted
Indebtedness  described  in clauses (i) through  (xi) of such  definition  or is
entitled  to be incurred  (whether  incurred  under the Bank Credit  Facility or
otherwise) pursuant to the proviso of the foregoing  sentence,  the Company may,
in its sole  discretion,  classify such item of  Indebtedness in any manner that
complies  with this  covenant and such item of  Indebtedness  will be treated as
having been incurred  pursuant too only one of such clauses of the definition of
Permitted  Indebtedness or the proviso of the foregoing  sentence and an item of
Indebtedness  may be  divided  and  classified  in more than one of the types of
Indebtedness permitted hereunder.

     (b) The amount of any guarantee by the Company or any Restricted Subsidiary
of any Indebtedness of the Company or one or more Restricted  Subsidiaries shall
not be deemed to be  outstanding  or incurred  for purposes of this Section 9.11
hereof in addition to the amount of Indebtedness which it guarantees.

     (c) For  purposes of this  Section  9.11,  Indebtedness  of any Person that
becomes a Restricted  Subsidiary by merger,  consolidation or other  acquisition
shall  be  deemed  to have  been  incurred  by the  Company  and the  Restricted
Subsidiary at the time such Person becomes a Restricted Subsidiary.

     Section 9.12 Additional Subsidiary Guarantors.

     (a) The Company shall cause each  Restricted  Subsidiary  that becomes,  or
comes  into  existence  as,  a  Restricted  Subsidiary  after  the  date of this
Indenture and has assets, businesses, divisions, real property or equipment with
a  Fair  Market  Value  in  excess  of  $5,000,000  to  execute  and  deliver  a
supplemental  indenture  to this  Indenture  agreeing  to be bound by its  terms
applicable to a Subsidiary Guarantor and providing for a Subsidiary Guarantee of
the Securities by such Restricted Subsidiary.

     (b)  Notwithstanding  the  foregoing  and  the  other  provisions  of  this
Indenture, any Subsidiary Guarantee incurred by a Restricted Subsidiary pursuant
to this Section 9.12 shall  provide by its terms that it shall be  automatically
and  unconditionally  released and discharged  upon the terms and conditions set
forth in Section 12.3 hereof.

     Section  9.13  Limitation  on  Issuances  and  Sales  of  Capital  Stock by
Restricted Subsidiaries.

     The Company (a) shall not permit any Restricted Subsidiary to issue or sell
any Capital  Stock to any Person  other than to the Company or one of its Wholly
Owned Restricted Subsidiaries or (b) permit any Person other than the Company or
one of its Wholly Owned Restricted  Subsidiaries to own any Capital Stock of any
other Restricted  Subsidiary except, in each case, for (i) directors' qualifying
shares,  (ii) the Capital Stock of a Restricted  Subsidiary owned by a Person at


                                      E-194




the time such Restricted  Subsidiary became a Restricted  Subsidiary or acquired
by such Person in connection with the formation of the Restricted Subsidiary, or
transfers  thereof or (iii) a sale of all of the Capital  Stock of a  Restricted
Subsidiary owned by the Company or its Subsidiaries  effected in accordance with
Section  9.16  hereof,  (d)  Qualifying  TECONS or (e) any sale or  issuance  of
Capital Stock of a Foreign  Subsidiary that is required to be issued to or owned
by the government of a foreign  jurisdiction or individual or corporate citizens
of such foreign  jurisdiction  in order for such Foreign  Subsidiary to transact
business in such foreign jurisdiction,  provided, that any such sale or issuance
shall be deemed to be an Asset Sale to the extent  the  percentage  of the total
outstanding   Voting  Stock  of  such  Foreign  Subsidiary  owned  directly  and
indirectly  by the Company is reduced as a result of such sale or  issuance  and
any such sale or issuance  must be made in  compliance  with the  provisions  of
Section 9.16 hereof.

     Section 9.14 Limitation on Liens.

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,
directly or  indirectly,  create,  incur,  assume,  affirm or suffer to exist or
become effective any Lien of any kind,  except for Permitted Liens,  upon any of
their  respective  Properties,  whether now owned or acquired  after the date of
this  Indenture,  or any  income or profits  therefrom,  or assign or convey any
right to receive  income  thereon,  unless (a) in the case of any Lien  securing
Subordinated Indebtedness, the Securities are secured by a lien on such Property
or  proceeds  that is senior in priority to such Lien and (b) in the case of any
other Lien,  the Securities  are directly  secured  equally and ratably with the
obligation or liability secured by such Lien.

     Section 9.15 Purchase of Securities Upon Change of Control.

     (a) Upon the  occurrence  of a Change  of  Control,  the  Company  shall be
obligated to make an offer to purchase (a "Change of Control  Offer") all of the
then  Outstanding  Securities,  in whole or in part,  from the  Holders  of such
Securities in integral  multiples of $1,000, at a purchase price (the "Change of
Control Purchase Price") equal to 101% of the aggregate principal amount of such
Securities,  plus accrued and unpaid interest,  if any, to the Change of Control
Purchase Date (as defined below), in accordance with the procedures set forth in
paragraphs (b), (c) and (d) of this Section.  The Company shall,  subject to the
provisions  described  below,  be required to purchase all  Securities  properly
tendered  into the Change of Control Offer and not  withdrawn.  The Company will
not be  required  to make a Change of Control  Offer upon a Change of Control if
another Person makes the Change of Control Offer at the same purchase  price, at
the same times and otherwise in  substantial  compliance  with the  requirements
applicable  to a Change of Control Offer to be made by the Company and purchases
all Securities  validly  tendered and not withdrawn under such Change of Control
Offer.

     (b) The Change of Control  Offer is required to remain open for at least 20
Business Days and until the close of business on the fifth Business Day prior to
the Change of Control Purchase Date (as defined below).

     (c) Not  later  than the 30th day  following  any  Change of  Control,  the
Company  shall give to the Trustee in the manner  provided  in Section  13.4 and
each Holder of the  Securities in the manner  provided in Section 13.5, a notice
(the "Change of Control  Notice")  governing  the terms of the Change of Control
Offer and stating:

          (1) that a Change in Control has occurred and that such Holder has the
     right to require the Company to  repurchase  such Holder's  Securities,  or
     portion thereof, at the Change of Control Purchase Price;

          (2) any  information  regarding such Change of Control  required to be
     furnished  pursuant  to Rule  13e-1  under the  Exchange  Act and any other
     securities laws and regulations thereunder;


                                      E-195





          (3) a purchase  date (the  "Change of Control  Purchase  Date")  which
     shall be on a Business  Day and no  earlier  than 30 days nor later than 60
     days from the date the Change of Control occurred;

          (4) that any Security,  or portion  thereof,  not tendered or accepted
     for payment will continue to accrue interest:

          (5) that unless the  Company  defaults  in  depositing  money with the
     Paying Agent in  accordance  with the last  paragraph of clause (d) of this
     Section 9.15, or payment is otherwise prevented,  any Security,  or portion
     thereof, accepted for payment pursuant to the Change of Control Offer shall
     cease to accrue interest after the Change of Control Purchase Date; and

          (6) the  instructions  a  Holder  must  follow  in  order  to have his
     Securities repurchased in accordance with paragraph (d) of this Section.

If any of the  Securities  subject to the Change of Control Offer is in the form
of a Global Security, then the Company shall modify the Change of Control Notice
to the  extent  necessary  to  accord  with  the  procedures  of the  depository
applicable thereto.

     (d)  Holders  electing  to have  Securities  purchased  will be required to
surrender  such  Securities to the Paying Agent at the address  specified in the
Change of  Control  Notice at least  five  Business  Days prior to the Change of
Control  Purchase  Date.  Holders will be entitled to withdraw their election if
the Paying  Agent  receives,  not later than  three  Business  Days prior to the
Change of Control Purchase Date, a telegram,  telex,  facsimile  transmission or
letter  setting  forth  the  name of the  Holder  and  principal  amount  of the
Securities  delivered  for purchase by the Holder as to which his election is to
be withdrawn  and a statement  that such Holder is  withdrawing  his election to
have such Securities  purchased.  Holders whose Securities are purchased only in
part will be issued new Securities  equal in principal amount to the unpurchased
portion of the Securities surrendered.

     On the Change of Control  Purchase  Date,  the Company shall (i) accept for
payment  Securities or portions thereof validly tendered pursuant to a Change of
Control  Offer,  (ii) deposit with the Paying Agent money  sufficient to pay the
purchase  price of all  Securities  or portions  thereof so tendered,  and (iii)
deliver or cause to be delivered to the Trustee the Securities so accepted.  The
Paying  Agent shall  promptly  mail or deliver to Holders of the  Securities  so
tendered  payment in an amount equal to the purchase  price for the  Securities,
and the Company  shall execute and the Trustee  shall  authenticate  and mail or
make  available  for delivery to such Holders a new Security  equal in principal
amount to any unpurchased  portion of the Security which any such Holder did not
surrender  for purchase.  The Company shall  announce the results of a Change of
Control Offer on or as soon as practicable  after the Change of Control Purchase
Date.  For  purposes of this  Section  9.15,  the Trustee will act as the Paying
Agent.

     (e) The Company shall comply with Rule 14e-1 under the Exchange Act and any
other  securities  laws and  regulations  thereunder to the extent such laws and
regulations are applicable, in the event that a Change of Control occurs and the
Company is required to purchase Securities as described in this Section 9.15.

     Section 9.16 Limitation on Asset Sales.

     (a) The  Company  shall not,  and shall not  permit  any of its  Restricted
Subsidiaries  to,  consummate  any Asset  Sale  unless  (i) the  Company or such
Restricted Subsidiary, as the case may be, receives consideration at the time of
such Asset Sale at least equal to the Fair Market Value of the Property  subject
to such Asset Sale and (ii) all of the consideration paid to the Company or such
Restricted Subsidiary in connection with such Asset Sale is in the form of cash,


                                      E-196




Cash Equivalents,  Liquid Securities,  Exchanged Properties or the assumption by
the  purchaser of  liabilities  of the Company  (other than  liabilities  of the
Company that are by their terms  subordinated  to the Securities) or liabilities
of any Subsidiary Guarantor that made such Asset Sale (other than liabilities of
a Subsidiary  Guarantor that are by their terms  subordinated to such Subsidiary
Guarantor's Subsidiary Guarantee), in each case as a result of which the Company
and  its  remaining  Restricted  Subsidiaries  are no  longer  liable  for  such
liabilities ("Permitted Consideration"); provided, however, that the Company and
its Restricted  Subsidiaries  shall be permitted to receive  Property other than
Permitted Consideration,  so long as the aggregate Fair Market Value of all such
Property other than Permitted  Consideration  received from Asset Sales and held
by the  Company or any  Restricted  Subsidiary  at any one time shall not exceed
7.5% of Adjusted  Consolidated Net Tangible Assets.  The Net Available Cash from
Asset  Sales by the  Company or a  Restricted  Subsidiary  may be applied by the
Company  or such  Restricted  Subsidiary,  to the  extent  the  Company  or such
Restricted  Subsidiary  elects  (or is  required  by  the  terms  of any  Senior
Indebtedness  of  the  Company  or  a  Subsidiary   Guarantor),   to  (i)  repay
Indebtedness  of the Company  under the Bank Credit  Facility,  (ii) reinvest in
Additional Assets (including by means of an Investment in Additional Assets by a
Restricted Subsidiary with Net Available Cash received by the Company or another
Restricted  Subsidiary) or (iii) purchase Securities or purchase both Securities
and one or more  series  or issues of other  Senior  Indebtedness  on a pro rata
basis (excluding  Securities and Senior  Indebtedness owned by the Company or an
Affiliate of the Company).  Pending any reinvestment  pursuant to clause (ii) in
the preceding sentence,  the Company may temporarily  prepay,  repay or purchase
Senior Indebtedness of the Company or a Subsidiary Guarantor.

     (b) Any Net  Available  Cash from an Asset Sale not  applied in  accordance
with the  preceding  paragraph  within 365 days from the date of such Asset Sale
shall constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $10,000,000,  the Company shall be required to make an offer to purchase
Securities having an aggregate principal amount equal to the aggregate amount of
Excess  Proceeds (the  "Prepayment  Offer") at a purchase price equal to 100% of
the principal  amount of such  Securities plus accrued and unpaid  interest,  if
any,  to the  Purchase  Date (as  defined)  in  accordance  with the  procedures
(including prorating in the event of oversubscription)  set forth herein. If the
aggregate principal amount of Securities tendered by Holders thereof exceeds the
amount  of  available  Excess  Proceeds,  then  such  Excess  Proceeds  shall be
allocated pro rata according to the principal amount of the Securities  tendered
and the Trustee  shall  select the  Securities  to be  purchased  in  accordance
herewith.  To the  extent  that any  portion  of the  amount of Excess  Proceeds
remains after compliance with the second sentence of this paragraph and provided
that all Holders of Securities  have been given the  opportunity to tender their
Securities  for purchase as described in the  following  paragraph in accordance
with this Indenture,  the Company and its Restricted  Subsidiaries  may use such
remaining  amount for  purposes  permitted by this  Indenture  and the amount of
Excess Proceeds shall be reset to zero.

     (c) (1) Within 30 days after the 365th day  following  the date of an Asset
Sale,  the Company  shall,  if it is  obligated to make an offer to purchase the
Securities pursuant to the preceding paragraph,  send a written Prepayment Offer
notice,  by  first-class  mail, to the Trustee and the Holders of the Securities
(the "Prepayment Offer Notice"),  accompanied by such information  regarding the
Company and its  Subsidiaries as the Company  believes shall enable such Holders
of the  Securities to make an informed  decision with respect to the  Prepayment
Offer  (which at a minimum  shall  include (i) the most  recently  filed  Annual
Report on Form 10-K (including audited consolidated financial statements) of the
Company, the most recent subsequently filed Quarterly Report on Form 10-Q of the
Company and any Current  Report on Form 8-K of the Company  filed  subsequent to
such  Quarterly  Report,  other than  Current  Reports  describing  Asset  Sales
otherwise  described  in the  offering  materials,  or  corresponding  successor
reports  (or,  during any time that the Company is not subject to the  reporting
requirements of Section 13 or 15(d) of the Exchange Act,  corresponding  reports
prepared  pursuant to Section 9.8), (ii) a description of material  developments
in the Company's  business  subsequent to the date of the latest of such reports
and  (iii) if  material,  appropriate  pro  forma  financial  information).  The
Prepayment Offer Notice shall state, among other things, (i) that the Company is
offering to purchase  Securities  pursuant to the provisions of this  Indenture,
(ii) that any Security (or any portion  thereof)  accepted for payment (and duly


                                      E-197




paid on the  Purchase  Date)  pursuant  to the  Prepayment  Offer shall cease to
accrue  interest on the Purchase  Date,  (iii) that any  Securities (or portions
thereof) not  properly  tendered  shall  continue to accrue  interest,  (iv) the
purchase  price and  purchase  date,  which  shall be,  subject to any  contrary
requirements of applicable law, no less than 30 days nor more than 60 days after
the date the Prepayment  Offer Notice is mailed (the "Purchase  Date"),  (v) the
aggregate principal amount of Securities to be purchased,  (vi) a description of
the procedure  which Holders of Securities  must follow in order to tender their
Securities and the procedures that Holders of Securities must follow in order to
withdraw an election to tender their  Securities for payment and (vii) all other
instructions  and  materials  necessary to enable  Holders to tender  Securities
pursuant to the Prepayment Offer.

          (2) Not later than the date upon which written  notice of a Prepayment
     Offer is  delivered  to the Trustee as provided  above,  the Company  shall
     deliver to the Trustee an Officers' Certificate as to (i) the amount of the
     Prepayment  Offer (the  "Offer  Amount"),  (ii) the  allocation  of the Net
     Available Cash from the Asset Sales pursuant to which such Prepayment Offer
     is  being  made  and  (iii)  the  compliance  of such  allocation  with the
     provisions  of  Section  9.16(a).  On such  date,  the  Company  shall also
     irrevocably  deposit  with the Trustee or with the Paying Agent (or, if the
     Company is the Paying Agent,  shall segregate and hold in trust) in cash an
     amount equal to the Offer Amount to be held for payment in accordance  with
     the provisions of this Section. Upon the expiration of the period for which
     the Prepayment Offer remains open (the "Offer  Period"),  the Company shall
     deliver to the Trustee for  cancellation the Securities or portions thereof
     which have been properly tendered to and are to be accepted by the Company.
     The  Trustee or the Paying  Agent  shall,  on the  Purchase  Date,  mail or
     deliver  payment to each  tendering  Holder in the  amount of the  purchase
     price.  In the event that the aggregate  purchase  price of the  Securities
     delivered by the Company to the Trustee is less than the Offer Amount,  the
     Trustee  or the  Paying  Agent  shall  deliver  the  excess to the  Company
     immediately  after the  expiration of the Offer Period for  application  in
     accordance with this Section.

          (3) Holders electing to have a Security purchased shall be required to
     surrender the Security,  with an appropriate  form duly  completed,  to the
     Company or its agent at the address  specified in the notice at least three
     Business  Days prior to the  Purchase  Date.  Holders  shall be entitled to
     withdraw  their  election if the Trustee or the Company  receives not later
     than one  Business  Day prior to the  Purchase  Date,  a  telegram,  telex,
     facsimile  transmission or letter setting forth the name of the Holder, the
     principal  amount of the Security  which was  delivered for purchase by the
     Holder and a statement that such Holder is withdrawing his election to have
     such  Security  purchased.  If at the  expiration  of the Offer  Period the
     aggregate principal amount of Securities surrendered by Holders exceeds the
     Offer Amount,  the Company shall select the Securities to be purchased on a
     pro rata basis (with such  adjustments as may be deemed  appropriate by the
     Company so that only  Securities in  denominations  of $1,000,  or integral
     multiples  thereof,  shall be  purchased).  Holders  whose  Securities  are
     purchased  only in part shall be issued new  Securities  equal in principal
     amount to the unpurchased portion of the Securities surrendered.

          (4) At the time the Company  delivers  Securities to the Trustee which
     are to be  accepted  for  purchase,  the  Company  shall  also  deliver  an
     Officers'  Certificate  stating that such  Securities are to be accepted by
     the Company  pursuant to and in  accordance  with the terms of this Section
     9.16. A Security  shall be deemed to have been accepted for purchase at the
     time the Trustee or the Paying Agent mails or delivers  payment therefor to
     the surrendering Holder.

     (d)  The  Company  shall  comply,  to  the  extent  applicable,   with  the
requirements of Rule 14e-1 under the Exchange Act and any other  securities laws
or regulations thereunder to the extent such laws and regulations are applicable
in connection with the purchase of Securities as described  above. To the extent
that the  provisions of any  securities  laws or  regulations  conflict with the
provisions  relating to the Prepayment  Offer, the Company shall comply with the
applicable  securities  laws and  regulations  and  shall  not be deemed to have
breached its obligations described above by virtue thereof.

                                      E-198





     Section 9.17 Limitation on Transactions with Affiliates.

     The  Company  shall  not,  and  shall  not  permit  any of  its  Restricted
Subsidiaries  to,  directly  or  indirectly,  enter  into or suffer to exist any
transaction or series of related  transactions  (including,  without limitation,
the sale,  purchase,  exchange  or lease of  Property  or the  rendering  of any
services)  with, or for the benefit of, any Affiliate of the Company (other than
the  Company  or  a  Wholly  Owned  Restricted  Subsidiary),   unless  (a)  such
transaction  or  series of  related  transactions  is on terms  that are no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
would be available in a comparable  transaction in arm's-length dealings with an
unrelated  third party,  (b) with respect to a transaction  or series of related
transactions  involving aggregate payments in excess of $2,500,000,  the Company
delivers  an  Officers'   Certificate  to  the  Trustee   certifying  that  such
transaction or series of related transactions complies with clause (a) above and
that such  transaction or series of related  transactions has been approved by a
majority of the Disinterested  Directors of the Company, and (c) with respect to
any one  transaction  or  series of  related  transactions  involving  aggregate
payments in excess of  $10,000,000,  the  Officers'  Certificate  referred to in
clause (b) above also certifies that the Company has obtained a written  opinion
from an independent  nationally  recognized investment banking firm or appraisal
firm  specializing  or having a speciality in the type and subject matter of the
transaction or series of related  transactions at issue,  which opinion shall be
to the effect set forth in clause (a) above or shall state that such transaction
or series of related  transactions is fair from a financial point of view to the
Company or such Restricted  Subsidiary;  provided,  however,  that the foregoing
restriction shall not apply to (i) loans or advances to officers,  directors and
employees  of the  Company or any  Restricted  Subsidiary  made in the  ordinary
course of business in an aggregate amount not to exceed  $1,000,000  outstanding
at any one time, (ii)  indemnities of officers,  directors,  employees and other
agents of the  Company  or any  Restricted  Subsidiary  permitted  by  corporate

the payment of reasonable  and customary fees to directors of the Company or any
of its  Restricted  Subsidiaries  who are not  employees  of the  Company or any
Affiliate,   (iv)  the  Company's   employee   compensation  and  other  benefit
arrangements,  (v) transactions exclusively between or among the Company and any
of the Restricted  Subsidiaries or exclusively  between or among such Restricted
Subsidiaries,  provided such  transactions  are not otherwise  prohibited by the
Indenture, and (vi) any Restricted Payment permitted to be paid pursuant Section
9.9.

     Section  9.18  Limitation  on  Dividends  and  Other  Payment  Restrictions
                    Affecting Restricted Subsidiaries.

     The Company shall not, and shall not permit any  Restricted  Subsidiary to,
directly or indirectly,  create or suffer to exist or allow to become  effective
any  consensual  encumbrance  or  restriction  of any kind on the ability of any
Restricted  Subsidiary to (a) pay dividends,  in cash or otherwise,  or make any
other  distributions  on or in respect of its Capital Stock, or make payments on
any Indebtedness owed, to the Company or any other Restricted Subsidiary, (b) to
make loans or advances to the Company or any other Restricted  Subsidiary or (c)
to  transfer  any of  its  Property  to the  Company  or  any  other  Restricted
Subsidiary (any such  restrictions  being  collectively  referred to herein as a
"Payment  Restriction"),  except for such encumbrances or restrictions  existing
under  or by  reason  of (i)  customary  provisions  restricting  subletting  or
assignment  of any lease  governing a  leasehold  interest of the Company or any
Restricted  Subsidiary,  or customary  restrictions in licenses  relating to the
Property  covered  thereby and entered into in the ordinary  course of business,
(ii) any instrument  governing  Indebtedness of a Person acquired by the Company
or any Restricted Subsidiary at the time of such acquisition,  which encumbrance
or restriction is not applicable to any other Person,  other than the Person, or
the Property of the Person, so acquired, provided that such Indebtedness was not
incurred in anticipation  of such  acquisition or (iii) the Bank Credit Facility
as in  effect  on the  date of this  Indenture  or any  agreement  that  amends,
modifies,  supplements,  restates,  extends, renews,  refinances or replaces the

Restriction  thereunder are not materially  less favorable to the Holders of the
Securities than those under the Bank Credit Facility as in effect on the date of

     Section 9.19 Limitation on Sale and Leaseback Transactions.

     The  Company  will  not,  and  will  not  permit  any  of  its   Restricted
Subsidiaries  to,  enter  into any  Sale/Leaseback  Transaction  unless  (i) the
Company  or such  Restricted  Subsidiary,  as the case may be,  would be able to
incur  Indebtedness  in an amount equal to the  Attributable  Indebtedness  with
respect  to  such  Sale/Leaseback  Transaction  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 Cash and Excess Proceeds
from an Asset Sale.

     Section 9.20 Waiver of Certain Covenants.

     The  Company may omit in any  particular  instance to comply with any term,
provision or condition set forth in Sections 9.5 through 9.11, Sections 9.13 and
9.14 and Sections 9.17 through 9.19 hereof if, before or after the time for such
compliance,  the Holders of at least a majority in aggregate principal amount of
the Outstanding Securities and the Subsidiary Guarantors, by Act of such Holders
and written  agreement of the Subsidiary  Guarantors,  waive such  compliance in
such instance with such term,  provision or condition,  but no such waiver shall
extend to or affect such term,  provision or  condition  except to the extent so
expressly waived, and, until such waiver shall become effective, the obligations
of the  Company  and the  duties of the  Trustee  in  respect  of any such term,
provision or condition shall remain in full force and effect.

                                   ARTICLE X.

                            REDEMPTION OF SECURITIES

     Section 10.1 Notice to Trustee.

     If the Company elects to redeem  Securities  pursuant to paragraph 5 of the
Securities,  it shall notify the Trustee in writing of the redemption  date, the
principal  amount of Securities to be redeemed and that such redemption is being
made pursuant to paragraph 5 of the Securities.

     The  Company  shall give each notice to the  Trustee  provided  for in this
Section at least 60 days before the Redemption Date unless the Trustee  consents
to  a  shorter  period.  Such  notice  shall  be  accompanied  by  an  Officers'
Certificate  and an Opinion of Counsel  from the Company to the effect that such
redemption  will  comply  with the  conditions  herein.  Any  election to redeem
Securities  shall be revocable  until the Company  gives a notice of  redemption
pursuant to Section 10.2 to the Holders of Securities to be redeemed.

     Section 10.2 Selection by Trustee of Securities to Be Redeemed.

     If  less  than  all  the  Securities  are to be  redeemed,  the  particular
Securities to be redeemed  shall be selected not less than 30 days nor more than
60 days  prior to the  Redemption  Date by the  Trustee,  from  the  Outstanding
Securities  not  previously  called for  redemption,  pro rata, by lot or by any
other  method  as the  Trustee  shall  deem fair and  appropriate  and which may
provide  for the  selection  for  redemption  of portions  of the  principal  of
Securities;  provided,  however,  that any such partial  redemption  shall be in
integral multiples of $1,000.

     The Trustee shall promptly  notify the Company in writing of the Securities
selected for redemption and, in the case of any Securities  selected for partial
redemption, the principal amount thereof to be redeemed.


                                      E-200





     For all purposes of this Indenture,  unless the context otherwise requires,
all provisions relating to redemption of Securities shall relate, in the case of
any  Security  redeemed  or to be redeemed  only in part,  to the portion of the
principal amount of such Security which has been or is to be redeemed.

     Section 10.3 Notice of Redemption.

     Notice of redemption  shall be given in the manner  provided for in Section
13.5 hereof not less than 30 nor more than 60 days prior to the Redemption Date,
to each Holder of Securities to be redeemed.

     All notices of redemption shall state:

     (a) the Redemption Date;

     (b) the Redemption Price;

     (c) if  less  than  all  Outstanding  Securities  are to be  redeemed,  the
identification (and, in the case of a partial redemption, the principal amounts)
of the particular Securities to be redeemed;

     (d) that on the Redemption Date the Redemption Price (together with accrued
interest,  if any, to the  Redemption  Date  payable as provided in Section 10.5
hereof)  will become due and  payable  upon each such  Security,  or the portion
thereof,  to be  redeemed,  and that,  unless the Company  shall  default in the
payment of the Redemption Price and any applicable  accrued  interest,  interest
thereon will cease to accrue on and after said date; and

     (e) the place or places where such  Securities  are to be  surrendered  for
payment of the Redemption Price.

     Notice of  redemption  of  Securities to be redeemed at the election of the
Company  shall be given by the  Company  or, at the  Company's  request,  by the
Trustee  in the name and at the  expense  of the  Company.  Failure to give such
notice by mailing to any Holder of  Securities  or any defect  therein shall not
affect the validity of any proceedings for the redemption of other Securities.

     Section 10.4 Deposit of Redemption Price.

     On or before 10:00 a.m.,  Eastern time, on any Redemption Date, the Company
shall  deposit  with the  Trustee or with a Paying  Agent (or, if the Company is
acting as its own  Paying  Agent,  segregate  and hold in trust as  provided  in
Section 9.3 hereof) an amount of money  sufficient to pay the  Redemption  Price
of, and  accrued  and unpaid  interest  on, all the  Securities  which are to be
redeemed on such Redemption Date.

     Section 10.5 Securities Payable on Redemption Date.

     Notice of redemption  having been given as aforesaid,  the Securities so to
be  redeemed  shall,  on the  Redemption  Date,  become  due and  payable at the
Redemption Price therein  specified  (together with accrued and unpaid interest,
if any,  to the  Redemption  Date),  and from and after  such date  (unless  the
Company  shall  default in the payment of the  Redemption  Price and accrued and
unpaid interest) such Securities shall cease to bear interest. Upon surrender of
any such Security for redemption in accordance  with said notice,  such Security
shall be paid by the Company at the Redemption Price,  together with accrued and
unpaid interest, if any, to the Redemption Date.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption,  the principal (and premium,  if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Securities.

                                      E-201





     Section 10.6 Securities Redeemed in Part.

     Any Security  which is to be redeemed only in part shall be  surrendered at
the office or agency of the  Company  maintained  for such  purpose  pursuant to
Section  9.2 hereof  (with,  if the  Company or the  Trustee  so  requires,  due
endorsement by, or a written  instrument of transfer in form satisfactory to the
Company and the Trustee duly  executed by, the Holder  thereof or such  Holder's
attorney duly  authorized in writing),  and the Company shall  execute,  and the
Trustee shall  authenticate  and deliver to the Holder of such Security  without
service charge, a new Security or Securities,  of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in exchange
for  the  unredeemed  portion  of  the  principal  amount  of  the  Security  so
surrendered.

                                   ARTICLE XI.

                       DEFEASANCE AND COVENANT DEFEASANCE

     Section 11.1 Company's Option to Effect Defeasance or Covenant Defeasance.

     The  Company  may,  at its option by Board  Resolution,  at any time,  with
respect to the  Securities,  elect to have either  Section  11.2 or Section 11.3
hereof  be  applied  to all  Outstanding  Securities  upon  compliance  with the
conditions set forth below in this Article XI.

     Section 11.2 Defeasance and Discharge.

     Upon the  Company's  exercise  under  Section  11.1  hereof  of the  option
applicable to this Section 11.2, the Company and the Subsidiary Guarantors shall
be deemed to have been discharged from their respective obligations with respect
to all  Outstanding  Securities on the date the  conditions set forth in Section
11.4 hereof are satisfied (hereinafter,  "legal defeasance").  For this purpose,
such legal defeasance means that the Company and the Subsidiary Guarantors shall
be deemed (i) to have paid and discharged their respective obligations under the
Outstanding Securities; provided, however, that the Securities shall continue to
be deemed to be "Outstanding"  for purposes of Section 11.5 hereof and the other
Sections of this Indenture referred to in clauses (A) and (B) below, and (ii) to
have satisfied all their other  obligations  with respect to such Securities and
this  Indenture  (and the Trustee,  at the expense and direction 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  11.4 hereof and as more fully
set forth in such Section,  payments in respect of the principal of (and premium
if any, on) and interest on such  Securities  when such  payments are due (or at
such time as the Securities  would be subject to redemption at the option of the
Company in accordance with this  Indenture),  (B) the respective  obligations of
the Company and the  Subsidiary  Guarantors  under  Sections 2.3, 2.4, 2.5, 2.6,
2.7, 2.8,  2.9, 4.8,  4.14,  5.6,  5.9,  5.10,  9.2, 9.3, 12.1 (to the extent it
relates to the  foregoing  Sections and this Article XI),  12.4 and 12.5 hereof,
(C) the rights,  powers, trusts, duties and immunities of the Trustee hereunder,
and (D) the obligations of the Company and the Subsidiary  Guarantors under this
Article XI. Subject to compliance with this Article XI, the Company may exercise
its option  under this Section 11.2  notwithstanding  the prior  exercise of its
option under Section 11.3 hereof with respect to the Securities.

     Section 11.3 Covenant Defeasance.

     Upon the  Company's  exercise  under  Section  11.1  hereof  of the  option
applicable to this Section 11.3, the Company and each Subsidiary Guarantor shall
be released from their respective  obligations  under any covenant  contained in
Article  VII,  in  Sections  9.5  through  9.19 and in Section  12.2 hereof 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 to be "Outstanding"  for the purposes


                                      E-202




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.  For this
purpose,  such covenant  defeasance  means that, with respect to the Outstanding
Securities,  the Company and each  Subsidiary  Guarantor 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  4.1(c) or 4.1(d)  hereof,  but,  except as specified  above,  the
remainder of this Indenture and such Securities shall be unaffected thereby.

     Section 11.4 Conditions to Defeasance or Covenant Defeasance.

     The following shall be the conditions to application of either Section 11.2
or Section 11.3 hereof to the Outstanding Securities:

     (a)  The  Company  or  any  Subsidiary  Guarantor  shall  irrevocably  have
deposited  or  caused to be  deposited  with the  Trustee  (or  another  trustee
satisfying the requirements of Section 5.7 hereof who shall agree to comply with
the  provisions of this Article XI 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 United States dollars in an amount, or (B) U.S.  Government  Obligations
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,  money in an  amount,  or (C) a  combination  thereof,
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 Trustee (or
other qualifying  trustee) to pay and discharge,  the principal of (and premium,
if any, on) and interest on the  Outstanding  Securities on the Stated  Maturity
thereof (or  Redemption  Date, if  applicable),  provided that the Trustee shall
have been  irrevocably  instructed in writing by the Company to apply such money
or the  proceeds  of such U.S.  Government  Obligations  to said  payments  with
respect to the  Securities.  Before such a deposit,  the Company may give to the
Trustee,  in  accordance  with Section 10.1 hereof,  a notice of its election to
redeem all of the  Outstanding  Securities at a future date in  accordance  with
Article X hereof, which notice shall be irrevocable. Such irrevocable redemption
notice,  if given,  shall be given  effect in applying the  foregoing.  For this
purpose,  "U.S.  Government  Obligations"  means  securities that are (x) direct
obligations  of the United States of America for the timely payment of which its
full faith and credit is pledged or (y)  obligations  of a Person  controlled or
supervised by and acting as an agency or instrumentality of the United States of
America  the timely  payment of which is  unconditionally  guaranteed  as a full
faith and credit  obligation by the United States of America,  which,  in either
case,  are not callable or redeemable at the option of the issuer  thereof,  and
shall also include a depository  receipt issued by a bank (as defined in Section
3(a)(2) of the  Securities  Act),  as  custodian  with  respect to any such U.S.
Government  Obligation or a specific  payment of principal of or interest on any
such U.S.  Government  Obligation  held by such custodian for the account of the
holder of such  depository  receipt,  provided  that (except as required by law)
such  custodian is not  authorized to make any deduction from the amount payable
to the  holder  of such  depository  receipt  from any  amount  received  by the
custodian in respect of the U.S.  Government  Obligation or the specific payment
of principal of or interest on the U.S. Government  Obligation evidenced by such
depository receipt.

     (b) 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
Sections  4.1(h) and 4.1(i) are concerned,  at any time during the period ending
on the 91st day after the date of such deposit.

     (c) Such  legal  defeasance  or  covenant  defeasance  shall  not cause the
Trustee  to have a  conflicting  interest  under  this  Indenture  or the  Trust
Indenture Act with respect to any  securities  of the Company or any  Subsidiary
Guarantor.

                                      E-203





     (d) Such legal  defeasance  or  covenant  defeasance  shall not result in a
breach or  violation  of, or  constitute  a default  under,  any other  material
agreement or  instrument to which the Company or any  Subsidiary  Guarantor is a
party or by which it is bound,  as  evidenced  to the  Trustee  in an  Officers'
Certificate delivered to the Trustee concurrently with such deposit.

     (e) In the case of an election under Section 11.2 hereof, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the Company
has received from, or there has been published by, the Internal  Revenue Service
a ruling,  or (ii) since the date of this  Indenture  there has been a change in
the  applicable  federal  income tax laws,  in either  case  providing  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
(it being understood that (x) such Opinion of Counsel shall also state that such
ruling or applicable  law is  consistent  with the  conclusions  reached in such
Opinion  of  Counsel  and (y) the  Trustee  shall  be  under  no  obligation  to
investigate the basis or correctness of such ruling).

     (f) In the case of an election under Section 11.3 hereof, 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.

     (g)  The  Company  shall  have   delivered  to  the  Trustee  an  Officers'
Certificate and an Opinion of Counsel,  which,  taken  together,  state that all
conditions  precedent provided for relating to either the legal defeasance under
Section 11.2 hereof or the covenant  defeasance  under Section 11.3 (as the case
may be) have been complied with.

     Section  11.5  Deposited Money and U.S.  Government  Obligations to Be Held
                    in Trust; Other Miscellaneous Provisions.

     Subject to the provisions of the last paragraph of Section 9.3 hereof,  all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee--collectively for purposes of this
Section 11.5, the  "Trustee")  pursuant to Section 11.4 hereof 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
acting as its own 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  (and  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 all taxes,  fees or
other charges imposed on or assessed against the U.S.  Governmental  Obligations
deposited pursuant to Section 11.4 hereof or the principal and interest received
in respect  thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Securities.

     Anything in this  Article XI to the contrary  notwithstanding,  the Trustee
shall  deliver or pay to the Company from time to time upon Company  Request any
money or U.S.  Government  Obligations  held by it as provided  in Section  11.4
hereof  which,  in the opinion of a nationally  recognized  firm of  independent
public accountants expressed in a written certification thereof delivered to the
Trustee,  are in excess of the amount thereof which would then be required to be
deposited to effect an equivalent  legal defeasance or covenant  defeasance,  as
applicable, in accordance with this Article.



                                      E-204




     Section 11.6 Reinstatement.

     If the  Trustee  or any  Paying  Agent  is  unable  to apply  any  money in
accordance  with  Section  11.5 hereof by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such application,  then the Company's and the Subsidiary Guarantors' obligations
under this  Indenture  and the  Securities  shall be revived and  reinstated  as
though no deposit had occurred  pursuant to Section 11.2 or 11.3 hereof,  as the
case may be,  until such time as the  Trustee or Paying  Agent is  permitted  to
apply all such money in accordance with Section 11.5 hereof; provided,  however,
that if the Company or any Subsidiary  Guarantor  makes any payment of principal
of  (or  premium,  if  any,  on)  or  interest  on any  Security  following  the
reinstatement of its obligations, the Company or such Subsidiary Guarantor 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.

                                  ARTICLE XII.

                              SUBSIDIARY GUARANTEES

     Section 12.1 Unconditional Guarantee.

     Each Subsidiary  Guarantor hereby  unconditionally,  jointly and severally,
guarantees  (each such guarantee  being  referred to herein as this  "Subsidiary
Guarantee," with all such guarantees being referred to herein as the "Subsidiary
Guarantees")  to each Holder of  Securities  authenticated  and delivered by the
Trustee and to the Trustee and its successors  and assigns,  the full and prompt
performance of the Company's obligations under this Indenture and the Securities
and that:

     (a)  the  principal  of (and  premium,  if any,  on)  and  interest  on the
Securities  will be  promptly  paid in full when due,  whether at  maturity,  by
acceleration,  redemption or otherwise, and interest on the overdue principal of
and  interest on the  Securities,  if any, to the extent  lawful,  and all other
obligations of the Company to the Holders or the Trustee hereunder or thereunder
will be promptly  paid in full or performed,  all in  accordance  with the terms
hereof and thereof; and

     (b) in  case  of any  extension  of  time  of  payment  or  renewal  of any
Securities or of any such other  obligations,  the same will be promptly paid in
full when due or  performed  in  accordance  with the terms of the  extension or
renewal,  whether at Stated  Maturity,  by acceleration  or otherwise;  subject,
however,  in the case of clauses (a) and (b) above, to the limitations set forth
in Section 12.4 hereof.

     Failing  payment when due of any amount so guaranteed or any performance 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, to the extent permitted by
law,  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, to the extent permitted by
law, 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 its Subsidiary  Guarantee  will not be discharged  except by
complete  performance  of the  obligations  contained  in the  Securities,  this
Indenture  and in this  Subsidiary  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
Subsidiary Guarantee, to the extent theretofore discharged,  shall be reinstated
in full  force and  effect.  Each  Subsidiary  Guarantor  agrees it shall not be
entitled  to enforce  any right of  subrogation  in  relation  to the Holders in


                                      E-205




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 IV hereof for the purposes of
this  Subsidiary  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 IV hereof,  such  obligations  (whether  or not due and
payable) shall forthwith become due and payable by each Subsidiary Guarantor for
the purpose of this Subsidiary Guarantee.

     Section 12.2 Subsidiary Guarantors May Consolidate, etc., on Certain Terms.

     (a) Except as set forth in Article VII hereof,  nothing  contained  in this
Indenture or in any of the Securities shall prevent any  consolidation or merger
of a  Subsidiary  Guarantor  with or into  the  Company  or  another  Subsidiary
Guarantor or shall prevent any sale,  conveyance or other  disposition of all or
substantially  all the  Properties  of a Subsidiary  Guarantor to the Company or
another Subsidiary Guarantor.

     (b) Except as set forth in Article VII hereof,  nothing  contained  in this
Indenture or in any of the Securities shall prevent any  consolidation or merger
of a  Subsidiary  Guarantor  with or into a Person  other  than the  Company  or
another  Subsidiary  Guarantor  (whether or not  Affiliated  with the Subsidiary
Guarantor),  or  successive  consolidations  or  mergers  in which a  Subsidiary
Guarantor or its successor or successors  shall be a party or parties,  or shall
prevent any sale,  conveyance or other  disposition of all or substantially  all
the  Properties of a Subsidiary  Guarantor to a Person other than the Company or
another  Subsidiary  Guarantor  (whether or not  Affiliated  with the Subsidiary
Guarantor)  authorized to acquire and operate the same; provided,  however, that
(i) immediately after such transaction, and giving effect thereto, no Default or
Event of Default  shall have  occurred  as a result of such  transaction  and be
continuing,  (ii) such  transaction  shall not violate any of the  covenants  of
Sections 9.1 through 9.19 hereof,  and (iii) each  Subsidiary  Guarantor  hereby
covenants and agrees that, upon any such consolidation, merger, sale, conveyance
or other disposition, such Subsidiary Guarantor's Subsidiary Guarantee set forth
in this Article XII, and the due and punctual  performance and observance of all
of the  covenants  and  conditions  of this  Indenture  to be  performed by such
Subsidiary  Guarantor,  shall  be  expressly  assumed  (in the  event  that  the
Subsidiary  Guarantor  is  not  the  surviving  corporation  in  a  merger),  by
supplemental  indenture  satisfactory  in  form  to the  Trustee,  executed  and
delivered to the Trustee, by such Person formed by such  consolidation,  or into
which the Subsidiary  Guarantor  shall have merged,  or by the Person that shall
have  acquired such  Property  (except to the extent the following  Section 12.3
would  result in the release of such  Subsidiary  Guarantee,  in which case such
surviving  Person or transferee  of such Property  shall not have to execute any
such  supplemental  indenture  and  shall  not have to  assume  such  Subsidiary
Guarantor's  Subsidiary  Guarantee).  In the  case  of any  such  consolidation,
merger,  sale,  conveyance or other  disposition  and upon the assumption by the
successor  Person,  by  supplemental  indenture  executed  and  delivered to the
Trustee  and  satisfactory  in form  to the  Trustee  of the  due  and  punctual
performance  of all of the  covenants  and  conditions  of this  Indenture to be
performed by the Subsidiary  Guarantor,  such successor  Person shall succeed to
and be substituted  for the  Subsidiary  Guarantor with the same effect as if it
had been named herein as the initial Subsidiary Guarantor.

     Section 12.3 Release of Subsidiary Guarantors.

     Upon the sale or  disposition  (by  merger or  otherwise)  of a  Subsidiary
Guarantor (or all or substantially all of its Properties) to a Person other than
the Company or another  Subsidiary  Guarantor and pursuant to a transaction that
is otherwise in compliance with the terms of this  Indenture,  including but not
limited to the  provisions  of Section  12.2  hereof or  pursuant to Article VII
hereof,  such Subsidiary  Guarantor shall be deemed released from its Subsidiary
Guarantee and all related obligations under this Indenture;  provided,  however,
that any such  release  shall occur only to the extent that all  obligations  of
such  Subsidiary  Guarantor under all of its guarantees of, and under all of its
pledges of assets or other security  interests which secure,  other Indebtedness
of the Company or any other Restricted  Subsidiary  shall also  be released upon

                                      E-206





such  sale or other  disposition.  The  Trustee  shall  deliver  an  appropriate
instrument evidencing such release upon receipt of a Company Request accompanied
by an Officers'  Certificate and an Opinion of Counsel certifying that such sale
or other  disposition  was made by the Company in accordance with the provisions
of  this  Indenture.   Each  Subsidiary  Guarantor  that  is  designated  as  an
Unrestricted  Subsidiary in  accordance  with the  provisions of this  Indenture
shall be released  from its  Subsidiary  Guarantee  and all related  obligations
under this Indenture for so long as it remains an Unrestricted  Subsidiary.  The
Trustee shall deliver an appropriate instrument evidencing such release upon its
receipt of the Board Resolution  designating such Unrestricted  Subsidiary.  Any
Subsidiary  Guarantor  not released in  accordance  with this Section 12.3 shall
remain liable for the full amount of principal of (and premium,  if any, on) and
interest on the Securities as provided in this Article XII.

     Section 12.4 Limitation of Subsidiary Guarantors' Liability.

     Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby
confirm that it is the  intention of all such parties that the guarantee by such
Subsidiary  Guarantor  pursuant to its  Subsidiary  Guarantee  not  constitute a
fraudulent  transfer or conveyance for purposes of the Federal  Bankruptcy Code,
the Uniform Fraudulent  Conveyance Act, the Uniform  Fraudulent  Transfer Act or
any similar  federal or state law. To effectuate  the foregoing  intention,  the
Holders  and  each  Subsidiary  Guarantor  hereby  irrevocably  agree  that  the
obligations of such Subsidiary Guarantor under its Subsidiary 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  Subsidiary  Guarantee  or pursuant to Section 12.5 hereof,
result in the  obligations  of such  Subsidiary  Guarantor  under its Subsidiary
Guarantee not constituting such a fraudulent  conveyance or fraudulent transfer.
This  Section  12.4 is for  the  benefit  of the  creditors  of each  Subsidiary
Guarantor.

     Section 12.5 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 its Subsidiary  Guarantee,  such Funding  Guarantor
shall be entitled to a  contribution  from each other  Subsidiary  Guarantor (if
any) 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 that  Funding  Guarantor  in  discharging  the  Company's
obligations with respect to the Securities or any other  Subsidiary  Guarantor's
obligations with respect to its Subsidiary Guarantee.

     Section 12.6 Severability.

     In case any  provision  of this  Subsidiary  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.

                                  ARTICLE XIII.

                                  MISCELLANEOUS

     Section 13.1 Compliance Certificates and Opinions.

     Upon any application or request by the Company or any Subsidiary  Guarantor
to the Trustee to take any action  under any  provision of this  Indenture,  the
Company or such Subsidiary  Guarantor,  as the case may be, shall furnish to the
Trustee  such  certificates  and  opinions  as may be  required  under the Trust


                                      E-207




Indenture  Act or this  Indenture.  Each such  certificate  and each such  legal
opinion  shall be in the  form of an  Officers'  Certificate  or an  Opinion  of
Counsel,  as  applicable,  and  shall  comply  with  the  requirements  of  this
Indenture.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (1) a statement that each Person  signing such  certificate or opinion
     has read such covenant or condition  and the  definitions  herein  relating
     thereto;

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

          (3) a statement that, in the opinion of each such Person,  such Person
     has made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

          (4) a  statement  as to whether,  in the opinion of each such  Person,
     such condition or covenant has been complied with.

     The  certificates and opinions  provided  pursuant to this Section 13.1 and
the  statements  required  by this  Section  13.1 shall be  satisfactory  to the
Trustee and comply in all respects with TIA Sections 314(c) and (e).

     Section 13.2 Form of Documents Delivered to Trustee.

     In any case where  several  matters  are  required to be  certified  by, or
covered by an opinion of, any specified  Person,  it is not  necessary  that all
such  matters  be  certified  by, or covered by the  opinion  of,  only one such
Person,  or that they be so certified or covered by only one  document,  but one
such Person may certify or give an opinion  with respect to some matters and one
or more other such Persons as to other matters,  and any such Person may certify
or give an opinion as to such matters in one or several documents.

     Any  certificate  or  opinion  of an  officer  may be based,  insofar as it
relates to legal matters,  upon a certificate or opinion of, or  representations
by,  counsel,  unless such officer knows,  or in the exercise of reasonable care
should know, that the certificate or opinion or representations  with respect to
the matters upon which his  certificate or opinion is based are  erroneous.  Any
such Opinion of Counsel may be based,  insofar as it relates to factual matters,
upon an officers' certificate,  unless such counsel knows, or in the exercise of
reasonable care should know,  that the certificate  with respect to such matters
is erroneous.

     Where  any  Person  is  required  to  make,  give  or  execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

     Section 13.3 Acts of Holders.

     (a) Any request, demand, authorization,  direction, notice, consent, waiver
or other action  provided by this  Indenture to be given or taken by Holders may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such  Holders in person or by agents duly  appointed in writing;
and, except as herein  otherwise  expressly  provided,  such action shall become
effective when such  instrument or instruments are delivered to the Trustee and,
where it is hereby  expressly  required,  to the  Company.  Such  instrument  or
instruments (and the action embodied  therein and evidenced  thereby) are herein
sometimes  referred to as the "Act" of the Holders  signing such  instrument  or
instruments.  Proof  of  execution  of  any  such  instrument  or  of a  writing


                                      E-208




appointing  any such agent shall be sufficient for any purpose of this Indenture
and  conclusive  in favor of the Trustee and the Company,  if made in the manner
provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate  of a notary  public  or  other  officer  authorized  by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a  signer  acting  in a  capacity  other  than  his  individual  capacity,  such
certificate or affidavit  shall also constitute  sufficient  proof of authority.
The fact and date of the  execution of any such  instrument  or writing,  or the
authority  of the  Person  executing  the same,  may also be proved in any other
manner which the Trustee deems sufficient.

     (c) The ownership,  principal  amount and serial numbers of Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

     (d) If the  Company  shall  solicit  from the  Holders  of  Securities  any
request, demand, authorization, direction, notice, consent, waiver or other Act,
the Company  may, at its option,  by or pursuant to a Board  Resolution,  fix in
advance a record  date for the  determination  of Holders  entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so.  Notwithstanding  TIA Section
316(c),  such record date shall be the record date  specified  in or pursuant to
such Board  Resolution,  which shall be a date not earlier than the date 30 days
prior to the first solicitation of Holders generally in connection therewith and
not later than the date such solicitation is completed. If such a record date is
fixed, such request, demand,  authorization,  direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of  business  on such  record  date shall be deemed to be
Holders  for the  purposes  of  determining  whether  Holders  of the  requisite
proportion of Outstanding  Securities  have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that  purpose the  Outstanding  Securities  shall be computed as of
such record date, provided that no such  authorization,  agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective  pursuant to the  provisions  of this  Indenture not later than eleven
months after the record date.

     (e) Any request, demand, authorization,  direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security  issued upon the  registration of
transfer  thereof  or in  exchange  therefor  or in lieu  thereof  in respect of
anything  done,  omitted or suffered to be done by the Trustee or the Company in
reliance  thereon,  whether  or not  notation  of such  action is made upon such
Security.

     Section 13.4 Notices, etc. to Trustee, Company and Subsidiary Guarantors.

     Any request, demand,  authorization,  direction, notice, consent, waiver or
Act of Holders or other  document  provided or permitted by this Indenture to be
made upon, given or furnished to or filed with,

          (1) the Trustee by any Holder, the Company,  any Subsidiary  Guarantor
     or any holder of Senior  Indebtedness shall be sufficient for every purpose
     hereunder  if made,  given,  furnished  or filed in writing (in the English
     language) and delivered in person or mailed by certified or registered mail
     (return receipt requested) to the Trustee at its Corporate Trust Office; or

          (2) the Company or any  Subsidiary  Guarantor by the Trustee or by any
     Holder shall be sufficient for every purpose  hereunder  (unless  otherwise
     herein  expressly  provided)  if in writing (in the English  language)  and
     delivered  in person or mailed by  certified  or  registered  mail  (return
     receipt  requested)  to  the  Company  or  such  Subsidiary  Guarantor,  as
     applicable,  addressed to it at the Company's  offices  located at 5005 LBJ


                                      E-209





     Freeway,  Suite 1000,  Dallas,  Texas  75244,  Attention:  Chief  Financial
     Officer,  or at any other  address  otherwise  furnished  in writing to the
     Trustee by the Company.

     Section 13.5 Notice to Holders; Waiver.

     Where  this  Indenture  provides  for notice of any event to Holders by the
Company  or the  Trustee,  such  notice  shall  be  sufficiently  given  (unless
otherwise herein expressly provided) if in writing (in the English language) and
mailed,  first-class  postage prepaid, to each Holder affected by such event, at
his address as it appears in the  Security  Register,  not later than the latest
date, and not earlier than the earliest date,  prescribed for the giving of such
notice.  In any case  where  notice to  Holders  is given by mail,  neither  the
failure to mail such  notice,  nor any  defect in any  notice so mailed,  to any
particular  Holder shall affect the  sufficiency  of such notice with respect to
other  Holders.  Any notice mailed to a Holder in the manner  herein  prescribed
shall be  conclusively  deemed to have been received by such Holder,  whether or
not such Holder actually receives such notice. Where this Indenture provides for
notice  in any  manner,  such  notice  may be waived in  writing  by the  Person
entitled to receive  such  notice,  either  before or after the event,  and such
waiver  shall be the  equivalent  of such  notice.  Waivers of notice by Holders
shall be filed  with the  Trustee,  but such  filing  shall  not be a  condition
precedent to the validity of any action taken in reliance upon such waiver.

     In case by reason of the  suspension of or  irregularities  in regular mail
service  or by reason  of any other  cause,  it shall be  impracticable  to mail
notice of any event to Holders when such notice is required to be given pursuant
to any  provision  of this  Indenture,  then any manner of giving such notice as
shall be satisfactory  to the Trustee shall be deemed to be a sufficient  giving
of such notice for every purpose hereunder.

     Section 13.6 Effect of Headings and Table of Contents.

     The Article and Section  headings  herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

     Section 13.7 Successors and Assigns.

     All  covenants  and  agreements  in this  Indenture  by the Company and the
Subsidiary  Guarantors  shall  bind their  respective  successors  and  assigns,
whether so  expressed or not. All  agreements  of the Trustee in this  Indenture
shall bind its successor.

     Section 13.8 Severability.

     In  case  any  provision  in this  Indenture  or in the  Securities  or the
Subsidiary Guarantees shall be invalid, illegal or unenforceable,  the validity,
legality and enforceability of the remaining  provisions shall not in any way be
affected or impaired thereby,  and a Holder shall have no claim therefor against
any party hereto.

     Section 13.9 Benefits of Indenture.

     Nothing in this Indenture or in the Securities,  express or implied,  shall
give to any  Person  (other  than the  parties  hereto,  any Paying  Agent,  any
Registrar  and their  successors  hereunder,  the Holders and, to the extent set
forth in Section 12.4 hereof, creditors of Subsidiary Guarantors and the holders
of Senior  Indebtedness) any benefit or any legal or equitable right,  remedy or
claim under this Indenture.


                                      E-210





     Section 13.10 Governing Law; Trust Indenture Act Controls.

     (a) THIS INDENTURE,  THE SUBSIDIARY  GUARANTEES AND THE SECURITIES SHALL BE
GOVERNED BY, AND  CONSTRUED  AND ENFORCED IN  ACCORDANCE  WITH,  THE LAWS OF THE
STATE OF NEW  YORK  BUT  WITHOUT  GIVING  EFFECT  TO  APPLICABLE  PRINCIPLES  OF
CONFLICTS  OF LAW TO THE  EXTENT  THAT THE  APPLICATION  OF THE LAWS OF  ANOTHER
JURISDICTION  WOULD  BE  REQUIRED  THEREBY.  THE  COMPANY  AND  EACH  SUBSIDIARY
GUARANTOR  IRREVOCABLY  SUBMIT TO THE  NON-EXCLUSIVE  JURISDICTION OF ANY UNITED
STATES FEDERAL OR NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN,  THE
CITY OF NEW YORK IN ANY ACTION OR PROCEEDING  ARISING OUT OF OR RELATING TO THIS
INDENTURE, THE SECURITIES OR THE SUBSIDIARY GUARANTEES, AND THE COMPANY AND EACH
SUBSIDIARY GUARANTOR IRREVOCABLY AGREE THAT ALL CLAIMS IN RESPECT OF SUCH ACTION
OR PROCEEDING MAY BE HEARD AND DETERMINED BY ANY SUCH COURT.

     (b) This Indenture is subject to the provisions of the Trust  Indenture Act
that  are  required  to be part of  this  Indenture  and  shall,  to the  extent
applicable,  be  governed  by such  provisions.  If and to the  extent  that any
provision of this  Indenture  limits,  qualifies  or  conflicts  with the duties
imposed by operation of Section 318(c) of the Trust  Indenture Act, or conflicts
with any provision  (an  "incorporated  provision")  required by or deemed to be
included in this  Indenture by operation  of such Trust  Indenture  Act section,
such imposed duties or incorporated provision shall control.

     Section 13.11 Legal Holidays.

     In any case where any Interest  Payment  Date,  Redemption  Date, or Stated
Maturity  or  Maturity  of any  Security  shall  not  be a  Business  Day,  then
(notwithstanding  any other  provision of this Indenture or of the Securities or
the Subsidiary Guarantee) payment of interest or principal (and premium, if any)
need not be made on such date, but may be made on the next  succeeding  Business
Day with the same  force and  effect as if made on the  Interest  Payment  Date,
Redemption Date or at the Stated Maturity or Maturity;  provided,  however, that
no interest  shall  accrue for the period from and after such  Interest  Payment
Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

     Section 13.12 No Recourse Against Others.

     A director, officer, employee,  stockholder,  incorporator or Affiliate, as
such, past, present or future, of the Company or any Subsidiary  Guarantor shall
not have any personal liability under the Securities or this Indenture by reason
of his or its status as a director, officer, employee, stockholder, incorporator
or  Affiliate  or any  liability  for  any  obligations  of the  Company  or any
Subsidiary  Guarantor  under the  Securities or this  Indenture or for any claim
based on, in respect of or by reason of such obligations or their creation. Each
Holder,  by  accepting  any of the  Securities,  waives  and  releases  all such
liability to the extent permitted by applicable law.

     Section 13.13 Duplicate Originals.

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

     Section 13.14 No Adverse Interpretation of Other Agreements.

     This Indenture may not be used to interpret another indenture, loan or debt
agreement of the Company or any of its Subsidiaries. Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.
