of  certificates  from  Euroclear  and  Clearstream  certifying  that  they have
received  certification of non-United States beneficial ownership of 100% of the
aggregate  principal amount of the Regulation S Temporary Global Note (except to
the extent of any  beneficial  owner  thereof who  acquired an interest  therein
during the Restricted  Period  pursuant to another  exemption from  registration
under the  Securities  Act and who will take delivery of a beneficial  ownership
interest  in a 144A  Global  Note  bearing a Private  Placement  Legend,  all as
contemplated  by Section  2.5(a)(ii)  hereof) and (ii) an Officers'  Certificate
from the Company certifying that a 40-day distribution compliance period (within

Regulation  S Permanent  Global  Notes  pursuant to the  Applicable  Procedures.

Guarantees   executed  by  the   Subsidiary   Guarantors   to  the  Trustee  for
authentication,  together  with a Company  Order  signed by two  officers of the
Company (the "Authentication Order") for the authentication and delivery of such
Notes, and the Trustee, in accordance with such Company Order, will authenticate
and deliver such Notes for original issue up to the aggregate  principal  amount
of $125,000,000 with the notations of Subsidiary  Guarantees thereon as provided
in this Indenture.

     No Note will be entitled to any benefit under this Indenture or be valid or
obligatory  for any purpose  unless there appears on such Note a certificate  of
authentication  substantially  in the form  provided for herein duly executed by
the Trustee by manual  signature  of the Trustee and such  certificate  upon any
Note will be conclusive evidence, and the only evidence, that such Note has been
duly  authenticated  and delivered  hereunder and is entitled to the benefits of
this Indenture.

     In case the Company,  pursuant to and in compliance  with Article 7 hereof,
will be  consolidated  or  merged  with or into any other  Person or will  sell,
convey,  transfer, lease or otherwise dispose of all or substantially all of its
Properties  to  any  Person,  and  the  successor  Person  resulting  from  such
consolidation,  or surviving  such  merger,  or into which the Company will have
been  merged,  or the  Person  which  will  have  received  a sale,  conveyance,
transfer,  lease or other  disposition  as  aforesaid,  will  have  executed  an
indenture supplemental hereto with the Trustee pursuant to Article 7 hereof, any
of the Notes  authenticated  or  delivered  prior to such  sale,  consolidation,
merger, conveyance, transfer, lease or other disposition may, from time to time,
at the request of the successor  Person be exchanged for other Notes executed in
the name of the successor  Person with such changes in  phraseology  and form as
may be  appropriate,  but otherwise in substance of like tenor as the securities
surrendered  for such exchange and of like  principal  amount;  and the Trustee,
upon Company  Request of the successor  Person,  will  authenticate  and deliver
Notes as specified in such  request for the purpose of such  exchange.  If Notes
will at any time be  authenticated  and delivered in any new name of a successor
Person  pursuant to this  Section 2.3 in  exchange or  substitution  for or upon
registration of transfer of any Notes,  such successor  Person, at the option of
the Holders but without  expense to them,  will  provide for the exchange of all
Notes at the time Outstanding for Notes  authenticated and delivered in such new
name.

                                       39

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

Paying  Agent,  the  Trustee  shall  act  as  such.  The  Company  or any of its
Subsidiaries  (including  any  Subsidiary  Guarantor) may act as Paying Agent or
Note Registrar.

     A Global Note may not be transferred as a whole except by the Depositary to
a nominee of the Depositary, by a nominee of the Depositary to the Depositary or
to another nominee of the  Depositary,  or by the Depositary or any such nominee
to a successor Depositary or a nominee of such successor Depositary.  All Global
Notes will be exchanged by the Company for  Definitive  Notes if (i) the Company
delivers to the Trustee  written notice from the Depositary that it is unwilling
or unable to  continue to act as  Depositary  or that it is no longer a clearing
agency  registered  under the  Exchange  Act and,  in either  case,  a successor
Depositary  is not  appointed  by the Company  within 120 days after the date of
such  notice  from the  Depositary  or (ii) the  Company in its sole  discretion
determines  that the Global Notes (in whole but not in part) should be exchanged
for  Definitive  Notes  and  delivers  a written  notice  to such  effect to the
Trustee;  provided that in no event shall the Regulation S Temporary Global Note
be exchanged by the Company for Definitive  Notes prior to (x) the expiration of
the  Restricted  Period  and  (y)  the  receipt  by the  Note  Registrar  of any
certificate required pursuant to Rule 903(b)(3)(ii)(B) under the Securities Act.

the Trustee in writing. Global Notes also may be exchanged or replaced, in whole
or in part, as provided in Sections 2.6 and 2.9 hereof. Every Note authenticated
and  delivered  in  exchange  for,  or in lieu of, a Global  Note or any portion
thereof,  pursuant to this  Section  2.5 or Section 2.6 or 2.9 hereof,  shall be

Indenture and the Applicable Procedures.  Beneficial interests in the Restricted
Global Notes shall be subject to  restrictions  on transfer  comparable to those
set forth  herein to the extent  required by the  Securities  Act.  Transfers of
beneficial  interests in the Global  Notes also shall  require  compliance  with
either subparagraph (i) or (ii) below, as applicable,  as well as one or more of
the other following subparagraphs, as applicable:

     (i) Transfer of  Beneficial  Interests in the Same Global Note.  Beneficial
interests in any  Restricted  Global Note may be transferred to Persons who take
delivery  thereof in the form of a  beneficial  interest in the same  Restricted
Global  Note in  accordance  with the  transfer  restrictions  set  forth in the
Private Placement Legend; provided, however, that prior to the expiration of the
Restricted Period, transfers of beneficial interests in the Temporary Regulation
S Global Note may not be made to a U.S.  Person or for the account or benefit of
a U.S. Person (other than the Initial  Purchaser).  Beneficial  interests in any
Unrestricted Global Note may be transferred to Persons who take delivery thereof
in the form of a beneficial  interest in an Unrestricted Global Note. No written
orders or  instructions  shall be required to be delivered to the Note Registrar
to effect the transfers described in this Section 2.5(b)(i).

                                       41


     (ii) All Other  Transfers and  Exchanges of Beneficial  Interests in Global
Notes.  In connection  with all transfers and exchanges of beneficial  interests
that are not  subject  to  Section  2.5(b)(i)  hereof,  the  transferor  of such

cause to be credited a beneficial  interest in another  Global Note in an amount
equal  to the  beneficial  interest  to be  transferred  or  exchanged  and  (2)
instructions  given in  accordance  with the  Applicable  Procedures  containing
information  regarding the Participant account to be credited with such increase
or (B) (1) a written order from a Participant or an Indirect  Participant  given
to the  Depositary in accordance  with the Applicable  Procedures  directing the
Depositary  to cause to be issued a  Definitive  Note in an amount  equal to the
beneficial interest to be transferred or exchanged and (2) instructions given by
the Depositary to the Note Registrar containing information regarding the Person
in whose name such Definitive Note shall be registered to effect the transfer or
exchange referred to in (B)(1) above; provided that in no event shall Definitive
securities  be issued upon the transfer or exchange of  beneficial  interests in
the  Regulation  S  Temporary  Global  Note prior to (x) the  expiration  of the
Restricted  Period and (y) the receipt by the Note Registrar of any  certificate
required  pursuant  to Rule  903(b)(3)(ii)(B)  under the  Securities  Act.  Upon
consummation  of an Exchange  Offer by the Company in  accordance  with  Section
2.5(f) hereof,  the  requirements of this Section  2.5(b)(ii) shall be deemed to
have been  satisfied  upon  receipt by the Note  Registrar  of the  instructions
contained  in the  Letter  of  Transmittal  delivered  by  the  holder  of  such
beneficial interests in the Restricted Global Notes. Upon satisfaction of all of
the  requirements  for  transfer or exchange of  beneficial  interests in Global
Notes  contained in this Indenture and the Notes or otherwise  applicable  under
the  Securities  Act,  the  Trustee  shall  adjust the  principal  amount of the
relevant Global Note(s) pursuant to Section 2.5(h) hereof.

     (iii) Transfer of Beneficial Interests to Another Restricted Global Note. A
beneficial interest in any Restricted Global Note may be transferred to a Person
who takes  delivery  thereof  in the form of a  beneficial  interest  in another
Restricted Global Note if the transfer complies with the requirements of Section
2.5(b)(ii) hereof and the Note Registrar receives the following:

            (A) if the transferee will take delivery in the form of a beneficial
         interest in the 144A Global Note,  then the  transferor  must deliver a
         certificate   in  the  form  of   Exhibit  B  hereto,   including   the
         certifications in item (1) thereof; and

            (B) if the transferee will take delivery in the form of a beneficial
         interest in the Regulation S Temporary  Global Note or the Regulation S
         Global Note, then the transferor must deliver a certificate in the form
         of Exhibit B hereto, including the certifications in item (2) thereof.

     (iv) Transfer and Exchange of Beneficial  Interests in a Restricted  Global
Note for  Beneficial  Interests  in the  Unrestricted  Global Note. A beneficial
interest in any  Restricted  Global Note may be exchanged by any holder  thereof
for a beneficial  interest in an  Unrestricted  Global Note or  transferred to a
Person who takes  delivery  thereof in the form of a  beneficial  interest in an
Unrestricted  Global  Note  if  the  exchange  or  transfer  complies  with  the
requirements of Section 2.5(b)(ii) hereof and:

                                       42


     (A) such exchange or transfer is effected pursuant to the Exchange Offer in
accordance  with  the  Registration  Rights  Agreement  and  the  holder  of the
beneficial  interest  to be  transferred,  in the  case of an  exchange,  or the
transferee,  in the case of a transfer,  certifies in the  applicable  Letter of
Transmittal  that it is not (1) a Broker-Dealer,  (2) a Person  participating in
the  distribution  of the Exchange Notes or (3) a Person who is an affiliate (as
defined in Rule 144) of the Company;

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

     (C) such transfer is effected by a  Broker-Dealer  pursuant to the Exchange
Offer  Registration   Statement  in  accordance  with  the  Registration  Rights
Agreement; or

            (1) if the holder of such beneficial interest in a Restricted Global
         Note  proposes to exchange  such  beneficial  interest for a beneficial
         interest in an Unrestricted Global Note, a certificate from such holder
         in the form of Exhibit C hereto,  including the  certifications in item
         (1)(a) thereof; or

            (2) if the holder of such beneficial interest in a Restricted Global
         Note  proposes to  transfer  such  beneficial  interest to a Person who
         shall take delivery thereof in the form of a beneficial  interest in an
         Unrestricted Global Note, a certificate from such holder in the form of
         Exhibit B hereto, including the certifications in item (4) thereof;

     and,  in each  such case set forth in this  subparagraph  (D),  if the Note
     Registrar  so  requests or if the  Applicable  Procedures  so  require,  an
     Opinion of Counsel in form  reasonably  acceptable to the Note Registrar to

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

Section 2.3 hereof,  the Trustee  shall  authenticate  one or more  Unrestricted
Global Notes in an aggregate  principal amount equal to the aggregate  principal

     (h) Cancellation and/or Adjustment of Global Notes.

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


                                       52


be made on such Global Note by the Trustee or by the Depositary at the direction
of the Trustee to reflect such increase.

     (i) General Provisions Relating to Transfers and Exchanges.

            (A) To permit registrations of transfers and exchanges,  the Company
         shall  execute  and the Trustee  shall  authenticate  Global  Notes and
         Definitive Notes upon receipt of an Authentication  Order in accordance
         with  Section  2.3 hereof or upon  receipt of a written  request of the
         Note Registrar.

            (B) No  service  charge  shall be made to a holder  of a  beneficial
         interest in a Global Note or to a Holder of a  Definitive  Note for any
         registration  of  transfer  or  exchange,  but the  Company may require
         payment  of a sum  sufficient  to cover  any  transfer  tax or  similar
         governmental  charge  payable in connection  therewith  (other than any
         such  transfer  taxes  or  similar  governmental  charge  payable  upon
         exchange or transfer  pursuant to Sections  2.9,  8.6,  9.15,  9.16 and
         10.8).

            (C) The  Note  Registrar  shall  not be  required  to  register  the
         transfer of or exchange any Note selected for redemption in whole or in
         part, except the unredeemed portion of any Note being redeemed in part.

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

            (E) The Company shall not be required (1) to issue,  to register the
         transfer of or to exchange any Notes  during a period  beginning at the
         opening of business 15 days  before the day of any  selection  of Notes
         for  redemption  under  Section  10.4 hereof and ending at the close of
         business on the day of selection, (2) to register the transfer of or to
         exchange  any  Note so  selected  for  redemption  in whole or in part,
         except the  unredeemed  portion of any Note being  redeemed in part, or
         (3) to register  the transfer of or to exchange a Note between a Record
         Date and the next succeeding Interest Payment Date.

            (F) Prior to due presentment  for the  registration of a transfer of
         any Note, the Trustee, any Agent and the Company may deem and treat the
         Person in whose name any Note is  registered  as the absolute  owner of
         such Note for the  purpose of  receiving  payment of  principal  of and
         interest  on such  Notes  and for all other  purposes,  and none of the
         Trustee,  any Agent or the  Company  shall be affected by notice to the
         contrary.

            (G) The Trustee shall authenticate Global Notes and Definitive Notes
         in accordance with the provisions of Section 3.3 hereof.

                                       53


            (H)  All  certifications,   certificates  and  Opinions  of  Counsel
         required to be submitted to the Note Registrar pursuant to this Section
         3.5 to effect a  registration  of transfer or exchange may be submitted
         by facsimile.

            (I) The  Trustee  shall  have  no  obligation  or  duty to  monitor,
         determine or inquire as to compliance with any restrictions on transfer
         imposed under this  Indenture or under  applicable  law with respect to
         any  transfer of any  interest  in any Note  (including  any  transfers
         between  or among  Depositary  participants  or  beneficial  owners  of
         interests  in any Global  Note) other than to require  delivery of such
         certificates  and other  documentation  or  evidence  as are  expressly
         required by, and to do so if and when  expressly  required by the terms
         of, this  Indenture,  and to examine the same to determine  substantial
         compliance as to form with the express requirement hereof.

     2.6 REPLACEMENT SECURITIES

     If (i) any mutilated Note is surrendered to the Trustee or (ii) the Company
and the Trustee receive evidence to their satisfaction of the destruction,  loss
or theft of any Note,  and there is  delivered to the  Company,  the  Subsidiary
Guarantors and the Trustee such security or indemnity as may be required by them
to save each of them harmless,  then, in the absence of notice to the Company or
the  Trustee  that such Note has been  acquired  by a bona fide  purchaser,  the
Company will execute,  and upon Company Order the Trustee will  authenticate and
deliver,  in  exchange  for any  such  mutilated  Note  or in  lieu of any  such
destroyed,  lost or stolen  Note, a new Note of the tenor and  principal  amount
bearing  a  number  not  contemporaneously   outstanding,   and  the  Subsidiary
Guarantors will execute the notation of Subsidiary Guarantees thereon.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable,  the Company in its discretion may,  instead of
issuing a new Note, pay such Note.

     Upon the  issuance of any new Note under this  Section 2.6, the Company may
require  payment  of a sum  sufficient  to cover  any tax or other  governmental
charge that may be imposed in relation thereto and any other expense  (including
the fees and expenses of the Trustee) connected therewith.

     Every  new  Note  issued  pursuant  to  this  Section  2.6 in  lieu  of any
mutilated, destroyed, lost or stolen Note will constitute an original additional
continual  obligation of the Company and the respective  Subsidiary  Guarantors,
whether or not the mutilated, destroyed, lost or stolen Note will be at any time
enforceable  by anyone,  and will be entitled to all benefits of this  Indenture
equally and proportionately with any and all other Notes duly issued hereunder.

     The  provisions of this Section 2.6 are exclusive and will preclude (to the
extent lawful) all other rights and remedies with respect to the  replacement or
payment of mutilated, destroyed, lost or stolen Notes.

     If  required by the  Trustee,  the Company or a  Subsidiary  Guarantor,  an
indemnity bond must be supplied by the Holder that is sufficient in the judgment
of the  Trustee,  the  Company  and each  Subsidiary  Guarantor  to protect  the
Company,   each   Subsidiary   Guarantor,   the  Trustee,   any  Agent  and  any


                                       54


authenticating  agent  from any loss  that any of them may  suffer  if a Note is
replaced. The Company and the Trustee may charge for their expenses in replacing
a Note.

     2.7 OUTSTANDING SECURITIES

     The Notes  outstanding at any time are all the Notes  authenticated  by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those  reductions  in the  interest in a Global Note  effected by the Trustee in
accordance with the provisions hereof and those described in this Section 2.7 as
not  outstanding.  Except as set forth in Section  2.8  hereof,  a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note.

     If a Note is  replaced  pursuant  to Section  2.6  hereof,  it ceases to be
outstanding  unless  the  Trustee  receives  proof  satisfactory  to it that the
replaced Note is held by a bona fide purchaser.

     If the principal  amount of any Note is  considered  paid under Section 9.1
hereof, it ceases to be outstanding and interest on it ceases to accrue.

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

     2.8 TREASURY SECURITIES

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

     2.9 TEMPORARY SECURITIES

     Pending the preparation of Definitive  Notes, the Company may execute,  and
upon Company Order the Trustee will  authenticate  and deliver,  temporary Notes
which  are  printed,  lithographed,   typewritten,   mimeographed  or  otherwise
produced,  in any  authorized  denomination,  substantially  of the tenor of the
Definitive  Notes in lieu of which they are issued and having the  notations  of
Subsidiary Guarantees thereon and with such appropriate  insertions,  omissions,
substitutions  and other  variations as the Authorized  Officers  executing such
Notes and notations of Subsidiary  Guarantees  may  determine,  as  conclusively
evidenced  by  their  execution  of  such  Notes  and  notations  of  Subsidiary
Guarantees.

     If temporary Notes are issued,  the Company will cause  Definitive Notes to
be prepared  without  unreasonable  delay.  After the  preparation of Definitive
Notes,  the  temporary  Notes will be  exchangeable  for  Definitive  Notes upon
surrender  of the  temporary  Notes  at the  office  or  agency  of the  Company
designated  for such  purpose  pursuant to Section  9.2,  without  charge to the
Holder.  Upon surrender for cancellation of any one or more temporary Notes, the


                                       55


Company will execute and the Trustee will  authenticate  and deliver in exchange
therefor a like principal amount of Definitive Notes of authorized denominations
having the notations of Subsidiary Guarantees thereon.  Until so exchanged,  the
temporary Notes will in all respects be entitled to the same benefits under this
Indenture as Definitive Notes.

     2.10 CANCELLATION

     All Notes surrendered for payment, redemption,  registration of transfer or
exchange will, if surrendered to any Person other than the Trustee, be delivered
to the Trustee and will be promptly  canceled by it. The Company may at any time
deliver to the Trustee for cancellation any securities previously  authenticated
and  delivered  hereunder  which the  Company  may have  acquired  in any manner
whatsoever, and all Notes so delivered will be promptly canceled by the Trustee.
No Notes will be  authenticated in lieu of or in exchange for any Notes canceled
as  provided  in this  Section  2.10,  except  as  expressly  permitted  by this
Indenture.  All  canceled  Notes  held  by the  Trustee  will  be  destroyed  in
accordance  with the Trustee's  usual  practice and a certificate of destruction
will be sent to the Company.

     2.11 DEFAULTED INTEREST

     Interest  on any Note  which is  payable,  and is  punctually  paid or duly
provided  for, on any Interest  Payment Date will be paid to the Person in whose
name such Note (or one or more Predecessor  Notes) is registered at the close of
business on the Regular Record Date for such interest at the office or agency of
the Company maintained for such purpose pursuant to Section 9.2 hereof.

     Any interest on any Note which is payable,  but is not  punctually  paid or
duly  provided  for, on any  Interest  Payment Date will  forthwith  cease to be
payable to the Holder on the  Regular  Record Date by virtue of having been such
Holder,  and such defaulted interest and (to the extent lawful) interest on such
defaulted  interest at the rate borne by the Notes (such defaulted  interest and
interest thereon herein collectively called "Defaulted Interest") may be paid by
the  Company,  at its  election in each case,  as provided in clause (i) or (ii)
below:

     (i) The Company may elect to make payment of any Defaulted  Interest to the
Persons in whose  names the Notes (or their  respective  Predecessor  Notes) are
registered at the close of business on a Special  Record Date for the payment of
such  Defaulted  Interest,  which  will be fixed in the  following  manner.  The
Company will notify the Trustee in writing of the amount of  Defaulted  Interest
proposed to be paid on each Note and the date of the  proposed  payment,  and at
the same time the Company will deposit with the Trustee an amount of money equal
in the  aggregate  amount  proposed  to be paid  in  respect  of such  Defaulted
Interest or will make arrangements  satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, and such money when deposited will be
held in trust for the benefit of the Persons entitled to such Defaulted Interest
as in this clause provided. Thereupon the Trustee will fix a Special Record Date
for the payment of such  Defaulted  Interest which will be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days  after the  receipt by the  Trustee  of the notice of the  proposed
payment.  The Trustee will  promptly  notify the Company of such Special  Record
Date,  and in the name and at the expense of the  Company,  will cause notice of
the proposed  payment of such  Defaulted  Interest  and the Special  Record Date


                                       56


therefor to be given in the manner provided for in Section 14.5 hereof, not less
than 10 days prior to such Special Record Date.  Notice of the proposed  payment
of such Defaulted  Interest and the Special Record Date therefor  having been so
given,  such  Defaulted  Interest will be paid to the Persons in whose names the
Notes (or their  respective  Predecessor  Notes) are  registered at the close of
business on such Special  Record Date and will no longer be payable  pursuant to
the following clause (ii).

     (ii) The Company may make  payment of any  Defaulted  Interest in any other
lawful manner not inconsistent with the requirements of any securities  exchange
on which the Notes may be listed,  and upon such  notice as may be  required  by
such  exchange,  if any, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause,  such manner of payment will be deemed
practicable by the Trustee.

     Subject  to the  foregoing  provisions  of this  Section  2.11,  each  Note
delivered  under this Indenture upon  registration of transfer of or in exchange
for or in lieu of any other Note will carry the rights to  interest  accrued and
unpaid, and to accrue, which were carried by such other Note.

     2.12 CUSIP NUMBERS

     The Company in issuing the Notes 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 Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification  numbers printed on
the Notes,  and any such  redemption  shall not be  affected by any defect in or
omission of such numbers.

     2.13 BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITY.

     Each Global Note will be registered in the name of the  Depositary for such
Global Note or the nominee of such Depositary and be delivered to the Trustee as
custodian for such  Depositary.  Members of, or participants  in, the Depositary
("Agent  Members")  will have no rights under this Indenture with respect to any
Global  Note  held on their  behalf by the  Depositary,  or the  Trustee  as its
custodian,  or under such Global Note,  and the Depositary may be treated by the
Company,  the Subsidiary  Guarantors,  the Trustee and any agent of the Company,
the  Subsidiary  Guarantors or the Trustee as the absolute  owner of such Global
Note for all purposes whatsoever.  Notwithstanding the foregoing, nothing herein
will prevent the Company, the Subsidiary  Guarantors or the Trustee or any agent
of the Company,  the Subsidiary  Guarantors or the Trustee from giving effect to
any  written  certification,  proxy  or  other  authorization  furnished  by the
Depositary or will impair, as between the Depositary and its Agent Members,  the
operation  of  customary  practices  governing  the  exercise of the rights of a
holder of any Note.

     Transfers of a Global Note will be limited to transfers of such Global Note
in whole, but not in part, to the Depositary, its successors or their respective
nominees.  Interests of beneficial owners in a Global Note may be transferred or
exchanged for  Definitive  Notes in accordance  with the rules and procedures of


                                       57


the Depositary. Definitive Notes will be transferred to all beneficial owners in
exchange for their beneficial interests in a Global Note if, and only if, either
(i) the  Depositary  notifies  the  Company  that it is  unwilling  or unable to
continue as  depositary  for the Global Note and a successor  depositary  is not
appointed  by the  Company  within  90 days of such  notice  or (ii) an Event of
Default has occurred and is  continuing  and the Note  Registrar  has received a
request  from  the  Depositary  to  issue  Definitive  Notes in lieu of all or a
portion of the Global Note (in which case the Company  will  deliver  Definitive
Notes within 30 days of such request).

     In  connection  with the  transfer of an entire  Global Note to  beneficial
owners  pursuant  to this  Section  2.13,  the Global  Note will be deemed to be
surrendered to the Trustee for cancellation,  and the Company will execute,  and
the Trustee will  authenticate and deliver,  to each beneficial owner identified
by the Depositary,  in exchange for its beneficial  interest in the Global Note,
an  equal  aggregate   principal   amount  of  Definitive  Notes  of  authorized
denominations.

     The Holder of the Global Note may grant proxies and otherwise authorize any
Person,  including  Agent  Members and Persons that may hold  interests  through
Agent Members,  to take any action which a Holder is entitled to take under this
Indenture or the Notes.

     2.14 COMPUTATION OF INTEREST.

     The amount of  interest  for each day that a Note is  Outstanding  shall be
calculated  by dividing the interest rate in effect for such Note on such day by
360 and multiplying  the result thereof by the principal  amount of such Note on
such day. Except as otherwise provided by the terms and provisions  contained in
a Note, the amount of interest to be paid on an Interest Payment Date in respect
of such Note shall be  calculated by adding the daily  interest  amount for each
day on which such Note is Outstanding  during the interest  period to which such
Interest Payment Date relates.

                                    ARTICLE 3
                           SATISFACTION AND DISCHARGE

     3.1 SATISFACTION AND DISCHARGE OF INDENTURE.

     This  Indenture  will upon Company  Request  cease to be of further  effect
(except as to surviving rights of registration of transfer or exchange of Notes,
as expressly  provided for in this Indenture) as to all Outstanding  Notes,  and
the Trustee,  at the expense of the Company,  will,  upon payment of all amounts
due  the  Trustee  under  Section  5.6  hereof,   execute   proper   instruments
acknowledging satisfaction and discharge of this Indenture when:

     (a) either

     (i) all Notes theretofore authenticated and delivered (other than (1) Notes
that have been mutilated, destroyed, lost or stolen and which have been replaced
or paid as  provided  in Section  2.6 hereof and (2) Notes for whose  payment of
money or United States governmental  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


                                       58


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

     (b)  all  such  Notes  not   theretofore   delivered  to  the  Trustee  for
cancellation

     (i) have become due and payable, or

     (ii) will become due and payable at their final  Stated  Maturity  within a
period of time that does not have more than one Interest Reset Date, or

     (iii) have been or are to be called for redemption, within a period of time
that does not have more than one  Interest  Reset  Date  under the terms of this
Indenture  for the serving 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 (b)(i),  (b)(ii) or (b)(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 the Notes not
theretofore  delivered to the Trustee for  cancellation,  for  principal of (and
premium,  if any,  on) and interest on the Notes to the date of such deposit (in
the case of Notes  which have become due and  payable)  or to such final  Stated
Maturity or Redemption Date, provided, that, if the day on which such deposit is
made is not after the  Interest  Reset  Date  immediately  preceding  such final
Stated  Maturity or redemption  date, as the case may be, the interest rate from
and after  such  Interest  Reset  Date used to  calculate  such  amount to be so
deposited  shall  be the  interest  rate on the  Notes  on the  day  immediately
preceding  such  Interest  Reset Date plus the greater of (a) 2.00% and (b) such
other percent as may be requested by the Trustee in order to provide  reasonable
assurance in the judgment of the Trustee that the amount being so deposited will
be sufficient  to pay and  discharge the principal of, and premium,  if any, and
interest on, the  Outstanding  Notes on such final 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;

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

     (d) the Company has delivered to the Trustee an Officers'  Certificate  and
an Opinion of Counsel,  in form and  substance  reasonably  satisfactory  to the
Trustee,  each  stating that all  conditions  precedent  herein  relating to the
satisfaction and discharge of this Indenture have been satisfied.

     Following the date upon which the entire principal of, and all premium,  if
any, and interest on, all of the Outstanding Notes is then due and payable,  the
Trustee shall unless there is then an Event of Default,  upon request made to it
by the Company, be required to pay to the Company the difference, if any, of (x)
the aggregate amount deposited with the Trustee in accordance with clause (a) of
the  immediately  preceding  paragraph  and  (y)  the  aggregate  amount  of any
principal of, and all premium,  if any, and interest on, the Notes which is then
due and payable.

                                       59


     Notwithstanding  the  satisfaction  and  discharge of this  Indenture,  the
obligations of the Company to the Trustee under Section 5.6 hereof and, if money
will have been  deposited  with the Trustee  pursuant to this  Section  3.1, the
obligations  of the Trustee under  Section 3.2 hereof and the last  paragraph of
Section 9.3 hereof will survive.

     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 will be held in
trust and applied by it, in accordance with the provisions of the Notes and this
Indenture,  to  the  payment,  either  directly  or  through  any  Paying  Agent
(including  the  Company  acting as its own  Paying  Agent) as the  Trustee  may
determine,  to the Persons entitled thereto,  of the principal (and premium,  if
any) and  interest  for whom  payment  such  money has been  deposited  with the
Trustee.

assignment for the benefit of creditors  under any such law, or the admission by
it in writing of its inability to pay its debts  generally as they become due or
the taking of corporate  action by the Company or any  Subsidiary in furtherance
of any such action.

     4.2 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

     If any  Event of  Default  (other  than an Event of  Default  specified  in
Section  4.1(j) or 4.1(k)  hereof)  occurs and is  continuing,  the Trustee,  by
written  notice to the  Company,  or the  Holders  of at least 25% in  aggregate
principal amount of the Notes then Outstanding, by notice to the Trustee and the
Company,  may,  and the Trustee upon the request of the Holders of not less than
25% in aggregate  principal  amount of the  Outstanding  Notes shall declare the
principal of, premium,  if any, and accrued interest on all of the Notes due and
payable  immediately,  upon which  declaration all amounts payable in respect of
the Notes will be immediately due and payable;  if an Event of Default specified
in Section 4.1(j) or 4.1(k) hereof occurs and is continuing,  then the principal
of, and  premium,  if any,  and  accrued  interest  on,  all of the Notes  shall
automatically become and be immediately due and payable without any declaration,
notice or other act on the part of the Trustee or any Holder.

     At any time after a declaration  of  acceleration  under this Indenture has
been made, but before a judgment or decree for payment of the money due has been
obtained by the Trustee or Holders of the Notes as hereinafter permitted in this
Article 4, the  Holders  of a  majority  in  aggregate  principal  amount of the
Outstanding Notes, by written notice to the Company,  the Subsidiary  Guarantors
and the Trustee,  may (i) rescind such declaration and its consequences and (ii)
on behalf of the Holders of all the Notes,  waive any existing  Event of Default
and its consequences,  except a continuing Event of Default specified in Section
4.1(a) hereof, if

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

         (i) all sums paid or advanced by the Trustee  under this  Indenture and
     the reasonable  compensation,  expenses,  disbursements and advances of the
     Trustee, its agents and counsel,

         (ii) all overdue interest on all Outstanding Notes,

         (iii) the unpaid principal of (and premium, if any, on) any Outstanding
     Notes  which  have  become  due  otherwise  than  by  such  declaration  of
     acceleration and interest thereon at the rate borne by the Notes, and

         (iv) to the extent that payment of such interest is lawful, interest on
     overdue  interest  and  overdue  principal  at the rate  borne by the Notes
     (without  duplication  of any amount paid or  deposited  pursuant to clause
     (ii) or (iii) above);

     (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

                                       62


     (c) all  Defaults  and Events of  Default,  other than the  non-payment  of
amounts of principal  of (or premium,  if any, on) or interest on the Notes that
have become due solely by such declaration of  acceleration,  have been cured or
waived as provided in this Indenture.

     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,  cure, waiver or rescission, as the case may be, will 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 Notes,  and so long as such
rescission  of any such  acceleration  of the Notes does not  conflict  with any
judgment or decree as certified to the Trustee by the Company.

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

     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  or
Liquidated  Damages,  if any,  on any Note 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 Note at the Stated Maturity thereof or with respect to any Note required
to have been  purchased by the Company on the Change of Control  Payment Date or
the Net  Proceeds  Payment  Date  pursuant  to a Change of Control  Offer or Net
Proceeds Offer, as applicable, the Company will, upon demand of the Trustee, pay
to the Trustee for the  benefit of the Holders of such Notes,  the whole  amount
then due and payable on each such Note 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 will be legally  enforceable,  upon any
overdue  installment  of  interest,  at the rate  borne by the  Notes,  and,  in
addition  thereto,  such further amount as will 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 Notes and collect the money


                                       63


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 Notes, 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
effective  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.

     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 Restricted  Subsidiary,  any
Subsidiary Guarantor or any other obligor upon the Notes, their creditors or the
Property of the Company, any Restricted Subsidiary,  any Subsidiary Guarantor or
of such other obligor, the Trustee (irrespective of whether the principal of the
Notes 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) will 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 Notes and to
file  such  other  papers or  documents  and take any  other  action,  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  moneys  or other  Property  payable  or
deliverable  on any such claim 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 amount due the Trustee
under Section 5.6 hereof.

     Nothing  herein  contained  will be  deemed to  authorize  the  Trustee  to
authorize  or  consent to or accept or adopt on behalf of any Holder any plan of
reorganization,  arrangement,  adjustment or composition  affecting the Notes or
the 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;  provided, however, that the Trustee may, on behalf of such Holders,
vote for the election of a trustee in bankruptcy or similar official.

     4.5 TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF SECURITIES.

     All rights of action and claims  under this  Indenture  or the Notes or the
Subsidiary  Guarantees may be prosecuted and enforced by the Trustee without the
possession  of any of the  Notes or the  production  thereof  in any  proceeding


                                       64


relating  thereto,  and any such  proceeding  instituted  by the Trustee will be
brought in its own name and as trustee of an express trust,  and any recovery of
judgment will,  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 Notes in respect of which such
judgment has been recovered.

     4.6 APPLICATION OF MONEY COLLECTED.

     Any money  collected  by the  Trustee  pursuant  to this  Article 4 will 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 Notes 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;

     SECOND:  to the payment of the amounts then due and unpaid for principal of
(and  premium,  if any, on) and interest on the Notes in respect of which or for
the benefit of which such money has been collected,  ratably, without preference
or priority of any kind,  according to the amounts due and payable on such Notes
for principal (and premium, if any) and interest, respectively; and

     THIRD: the balance, if any, to the Company;

provided that,  upon the occurrence and during the  continuation  of an Event of
Default  hereunder  or of an event of default  under the terms of the  Revolving
Credit  Facility or the Bridge Loan, all money collected by the Trustee shall be
promptly paid to the Collateral Agent for the account of the Secured Parties and
shall be applied pursuant to the terms of the Intercreditor Agreement.

     4.7 LIMITATION ON SUITS.

     No Holder of any Notes  will have any right to  institute  any  proceeding,
with respect to this Indenture, or any other remedy hereunder, unless:

     (a) such Holder has notified  the Trustee in writing of a continuing  Event
of Default;

     (b) the  Holders  of at least  25% in  aggregate  principal  amount  of the
Outstanding  Notes shall have made  written  request to the Trustee to institute
proceedings or pursue such remedy in respect of such Event of Default in its own
name as Trustee  hereunder  and  offered  to the  Trustee  reasonable  indemnity
satisfactory  to the Trustee  against the costs,  expenses and liabilities to be
incurred in compliance with the request;

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

     (d) no direction  inconsistent,  in the opinion of the  Trustee,  with such
written  request has been given to the Trustee  during such 60 day period by the
Holders of a majority in aggregate principal amount of the Outstanding Notes,

                                       65


it being understood and intended that no Holder shall have any right in any
manner by virtue of, or by availing of, any provision of this Indenture to
affect, disturb or prejudice the rights of any other Holder, or to obtain or to
seek to obtain priority or preference over any other Holder 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.

     4.8 UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PAYMENT.

     Notwithstanding  any other provision in this  Indenture,  the Holder of any
Note will have the  right,  which is  absolute  and  unconditional,  to  receive
payment, as provided herein and in such Note of the principal of (and premium if
any, on) and (subject to Article 2 hereof) interest and Liquidated  Damages,  if
any, on such Note on the  respective  Stated  Maturities  expressed in such Note
(or, in the case of redemption,  on the  Redemption  Date) and to institute suit
for the  enforcement  of any such payment,  and such rights will not be impaired
without the consent of such Holder.

     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 will be restored  severally and  respectively to their former  positions
hereunder  and all rights and  remedies  of the  Trustee  and the  Holders  will
continue as though no such proceeding had been instituted.

     4.10 RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise  provided with respect to the replacement or payment of
mutilated,  destroyed,  lost or stolen Notes  described in Article 2 hereof,  no
right or remedy  herein  conferred  upon or  reserved  to the  Trustee or to the
Holders is intended  to be  exclusive  of any other  right or remedy,  and every
right and remedy  will,  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,  will not  prevent  the  concurrent
assertion or employment of any other appropriate right or remedy.

     4.11 DELAY OR OMISSION NOT WAIVER.

     No  delay  or  omission  of the  Trustee  or of any  Holder  of any Note to
exercise any right or remedy occurring upon any Event of Default will impair any
such right or remedy or  constitute  a waiver of any such Event of Default or an
acquiescence  thereof.  Every right and remedy given by this Article 4 or by law
or in equity 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.

     4.12 CONTROL BY HOLDERS.

                                       66


     Subject to the provisions of the  Intercreditor  Agreement,  the Holders of
not less than a majority in aggregate  principal amount of the Outstanding Notes
will have the  right to direct  the time,  method  and place of  conducting  any
proceeding for any remedy  available to the Trustee,  or exercising any trust or
power conferred on the Trustee, provided that:

     (a) such  direction  will 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 be unduly prejudicial to the Holders not joining therein.

     4.13 WAIVER OF PAST DEFAULTS.

     The Holders of not less than a majority in  aggregate  principal  amount of
the Outstanding Notes may, on behalf of the Holders of all the Notes,  waive any
existing Default or Event of Default hereunder and its consequences,  except (i)
a Default or Event of Default in the payment of  principal  of, or  premium,  if
any, interest or Liquidated  Damages,  if any, on, the Notes, or (ii) in respect
of a  covenant  or  provision  hereof  which  under  Article 8 hereof  cannot be
modified or amended without the consent of the Holder of each  Outstanding  Note
affected thereby.

     Upon any such waiver,  such Default or Event of Default will cease to exist
for every  purpose under this  Indenture,  but no such waiver will extend to any
subsequent or other  Default or Event of Default or impair any right  consequent
thereto. Any such waiver may (but need not) be given in connection with a tender
offer or exchange offer for the Notes.

     4.14 WAIVER OF STAY.

     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, or
premium, if any, or interest on, the Notes 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 covenants
that it will not  hinder,  delay or impede  the  execution  of any power  herein
granted to the Trustee,  but will suffer and permit the  execution of every such
power as though no such law had been enacted.

                                   ARTICLE 5
                                   THE TRUSTEE

     5.1 DUTIES OF TRUSTEE.

     (a) If an Event of Default has occurred and is continuing, the Trustee will
exercise the rights and powers  vested in it by this  Indenture and use the same
degree of care and skill in its exercise as a prudent  person would  exercise or


                                       67


use under the circumstances in the conduct of such person's own affairs.

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

     (i) the Trustee  undertakes  to perform such duties and only such duties as
are  specifically  set  forth in this  Indenture  and no  implied  covenants  or
obligations will 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  will 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, the Trustee will examine the
certificates  and  opinions  to  determine  whether  or not they  conform to the
requirements of this Indenture (but need not confirm or investigate the accuracy
of mathematical calculations or other facts stated therein).

     (iii) No  provision  of this  Indenture  will be  construed  to relieve the
Trustee from liability for its own negligent  action,  its own negligent failure
to act or its own willful misconduct, except that:

            (A) this  subsection  will not be  construed  to limit the effect of
         Section 5.1(a) hereof;

            (B) the Trustee will 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;

            (C) the  Trustee  will 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 hereof; and

            (D) no  provision  of this  Indenture  shall  require the Trustee to
         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.

     (iv) Whether or not therein expressly so provided,  every provision of this
Indenture  relating to the conduct or  affecting  the  liability of or affording
protection  to the Trustee  shall be subject to the  provisions  of this Section
5.1.

conclusively rely upon an Officers' Certificate;

costs, expenses and liabilities which might be incurred by it in compliance with

     (h) the  Trustee  will not be liable  for any  action  taken,  suffered  or

discretion or rights or powers conferred upon it by this Indenture;

     (i) the  Trustee  will not be deemed to have  notice  or  knowledge  of any
matter (including any Default or Event of Default) unless a Responsible  Officer

Trustee at its  Corporate  Trust  Office and such  notice  references  the Notes
generally, the Company or this Indenture;

                                       69

have  reasonable  grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

     5.3 TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

     The  recitals  contained  herein  and in the  Notes  and the  notations  of
Subsidiary  Guarantees  thereon,   except  for  the  Trustee's  certificates  of
authentication, will 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 Subsidiary  Guarantees or the Notes,  except
that the Trustee  represents  that it is duly  authorized to execute and deliver
this Indenture,  authenticate  the Notes and perform its obligations  hereunder,
and  that  the  statements  made  by  it  in  a  Statement  of  Eligibility  and
Qualification on Form T-1 supplied to the Company are true and accurate, subject
to the qualifications set forth therein. The Trustee will not be accountable for
the use or application by the Company of Notes or the proceeds thereof.

     5.4 MAY HOLD SECURITIES.

     The Trustee,  any Paying Agent any Note Registrar or any other agent of the
Company,  the Subsidiary  Guarantors or of the Trustee, in its individual or any
other  capacity,  may  become  the owner or  pledgee  of Notes  and,  subject to
Sections  310(b) and 311 of the TIA 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,  Note  Registrar or such
other agent.

     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 will be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company or any Subsidiary Guarantor.

     5.6 COMPENSATION AND REIMBURSEMENT.

     The Company agrees:

                                       70


     (a) to pay to the  Trustee  from  time to  time  such  compensation  as the
Company  and the  Trustee  shall  from  time to time  agree in  writing  for all
services rendered by it hereunder (which compensation will 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  reasonable   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  willful  misconduct,
negligence or bad faith; and

     (c) to indemnify each of the Trustee or any  predecessor  Trustee and their
agents for,  and to hold them  harmless  against,  any and all loss,  liability,
damage, claim or expense, including taxes (other than those based upon, measured
by or  determined  by the  income  of the  Trustee),  incurred  without  willful
misconduct,  negligence  or bad  faith  on its  part  (i)  arising  out of or in
connection with the acceptance or  administration  of this trust,  including the
costs and expenses of defending  itself against any claim or liability  (whether
assisted by the Company,  any Holder or any other person) in connection with the
exercise  or  performance  of any of its powers or duties  hereunder  or (ii) in
connection with enforcing this indemnification provision.

     The  obligations  of the Company under this Section 5.6 to  compensate  the
Trustee,  to pay or  reimburse  the  Trustee  for  expenses,  disbursements  and
advances  and to  indemnify  and hold  harmless  the  Trustee  will  survive the
satisfaction and discharge of this Indenture or any other  termination under any
Insolvency  or  Liquidation  Proceeding  and the  resignation  or removal of the
Trustee. As security for the performance of such obligations of the Company, the
Trustee  will have a claim and lien  prior to the Notes  upon all  property  and
funds held or collected  by the Trustee as such,  except funds held in trust for
payment of principal  of (and  premium,  if any,  on) or interest on  particular
Notes.  Such lien will survive the  satisfaction and discharge of this Indenture
or any other termination under any Insolvency or Liquidation Proceeding.

     When the Trustee incurs  expenses or renders  services after the occurrence
of an Event of Default  specified in paragraph (j) or (k) of Section 4.1 hereof,
such expenses and the  compensation for such services are intended to constitute
expenses of administration under any Insolvency or Liquidation Proceeding.

     5.7 CORPORATE TRUSTEE REQUIRED: ELIGIBILITY.

     There will at all times be a Trustee  hereunder  which will be  eligible to
act as  Trustee  under  Section  310(a)(1)  of the TIA and will have a  combined
capital and surplus of at least  $10,000,000 in the case of the initial  Trustee
hereunder and $50,000,000 in the case of any successor  Trustee.  If such Person
publishes  reports of  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 Person will be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If at


                                       71


any time the Trustee will cease to be eligible in accordance with the provisions
of this  Section  5.7, it will resign  immediately  in the manner with which the
effect hereinafter specified in this Article 5.

     5.8 CONFLICTING INTERESTS.

     The Trustee will comply with the  provisions of Section  310(b) of the TIA;
provided,  however,  that there will be excluded  from the  operation of Section
310(b)(1) of the TIA any indenture or indentures under which other securities or
certificates of interest or participation in other securities of the Company are
Outstanding  if the  requirements  for  such  exclusion  set  forth  in  Section
310(b)(1) of the TIA are met. The duties and interests of the Trustee under this
Indenture  shall be subject to its duties as  Collateral  Agent and the security
interest established pursuant to the Intercreditor Agreement.

     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 5 will 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
Section 5.10 hereof will not have been  delivered to the Trustee  within 30 days
after the  giving of such  notice of  resignation,  the  resigning  Trustee  may
petition, at the Company's expense, any court of competent  jurisdiction for the
appointment of a successor Trustee.

     (c) The  Trustee may be removed at any time by an Act of the Holders of not
less than a majority in aggregate  principal  amount of the  Outstanding  Notes,
delivered to the Trustee and to the Company.

     (d) If at any time:

     (i) the Trustee shall have failed to comply with the  provisions of Section
310(b) of the TIA after written request therefor by the Company or by any Holder
who has been a bona fide Holder of a Note for at least six months; or

     (ii) the Trustee shall have ceased to be eligible  under Section 5.7 hereof
and shall have failed to resign after written request therefor by the Company or
by any Holder who has been a bona fide Holder of a Note for at least six months;
or

     (iii) the Trustee shall have become  incapable of acting or shall have been
adjudged  bankrupt or  insolvent or a receiver of the Trustee or of its property
will be  appointed or any public  officer  shall have taken 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, (A) the Company, by a Board
Resolution,  may remove the Trustee or (B) subject to Section 315(e) of the TIA,
any  Holder  who has been a bona fide  Holder of a Note for at least six  months
may, on behalf of itself and all others similarly  situated,  petition any court
of competent  jurisdiction for the removal of the Trustee and the appointment of
a successor Trustee.

                                       72


     (e) If the Trustee shall have resigned, been removed or become incapable of
acting,  or if a vacancy  shall have  occurred  in the office of Trustee for any
cause,  the Company,  by a Board  Resolution,  will promptly appoint a successor
Trustee. If, within one year after such resignation, removal or incapability, or
the occurrence of such vacancy, a successor Trustee shall have been appointed by
Act  of  the  Holders  of a  majority  in  aggregate  principal  amount  of  the
Outstanding  Notes  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,  any Holder who has been a bona fide Holder of a Note for at least six
months may, on behalf of itself 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 to this Indenture.

     (f) The Company  will give notice of each  resignation  and each removal of
the Trustee and each appointment of a successor  Trustee to the Holders of Notes
in the manner provided for in Section 14.5 hereof.  Each notice will include the
name of the successor Trustee and the address of its Corporate Trust Office.

     5.10 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     Every successor Trustee appointed  hereunder will 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
will become effective and such successor Trustee,  without any further act, deed
or conveyance, will 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 will,  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
will 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 will 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 will accept its appointment unless at the time of such
acceptance  such  successor  Trustee will be qualified  and eligible  under this
Article 5.

     5.11 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any  corporation  into which the Trustee may be merged or converted or with
which it may be  consolidated,  or any  corporation  resulting  from any merger,
conversion  or  consolidation  to which  the  Trustee  will be a  party,  or any
corporation  succeeding  to all or  substantially  all  of the  corporate  trust
business  of the  Trustee,  will  be the  successor  of the  Trustee  hereunder,
provided such  corporation  will be otherwise  qualified and eligible under this
Article 5,  without the  execution  or filing of any paper or any further act on
the  part of any of the  parties  hereto.  In case  any  Note  shall  have  been
authenticated,  but not delivered,  by the Trustee then in office, any successor


                                       73


by merger,  conversion or consolidation to such authenticating Trustee may adopt
such  authentication and deliver the Notes 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  Notes  shall  not have  been  authenticated,  any
successor  Trustee  may  authenticate  such  Notes  either  in the  name  of any
predecessor  hereunder or in the name of the successor Trustee;  and in all such
cases such  certificates  shall have the full force  which it is anywhere in the
Notes or in this  Indenture;  provided,  however,  that the  right to adopt  the
certificate of  authentication  of any  predecessor  Trustee or to  authenticate
Notes in the name of any predecessor Trustee will apply only to its successor or
successors by merger, conversion or consolidation.

     5.12 PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     If and when the  Trustee is or becomes a creditor  of the  Company  (or any
other obligor under the Notes), the Trustee will be subject to the provisions of
the Trust  Indenture Act regarding the  collection of claims against the Company
(or any such other obligor).

     5.13 NOTICE OF DEFAULTS.

     Within 60 days after the occurrence of any Default  hereunder,  the Trustee
will transmit in the manner and to the extent  provided in Section 313(c) of the
TIA, notice of such Default hereunder known to the Trustee,  unless such Default
will have been cured or waived; provided, however, that, except in the case of a
Default in the payment of the principal of, or premium,  Liquidated  Damages, or
interest on, any Note, the Trustee will be protected in withholding  such notice
if and so long as the board of directors of the Trustee,  committee of its board
of directors or a committee of Trust officers  determines in good faith that the
withholding of such notice is in the interest of the Holders.

                                   ARTICLE 6
                HOLDERS' LISTS AND REPORTS BY TRUSTEE AND COMPANY

     6.1 HOLDERS' LISTS; HOLDER COMMUNICATIONS; DISCLOSURES RESPECTING HOLDERS.

     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
the Holders. Neither the Company, any Subsidiary Guarantor nor the Trustee shall
have any responsibility with regard to the accuracy of such list. If the Trustee
is not the Note Registrar, the Company will furnish to the Trustee semi-annually
before  each  Regular  Record  Date,  and at such other times as the Trustee may
reasonably  request  in  writing,  a list,  in  such  form  as the  Trustee  may
reasonably  request,  as of such date of the names and  addresses of the Holders
then known to the  Company.  The Company and the Trustee  will also  satisfy any
other requirement imposed upon each of them by Section 312(a) of the TIA.

     Holders may  communicate  pursuant to Section  312(b) of the TIA with other
Holders with respect to their rights under this Indenture or the Notes.

     Every Holder of Notes,  by receiving and holding the same,  agrees with the
Company, the Subsidiary Guarantors,  the Note Registrar and the Trustee that (i)
none of the  Company,  the  Subsidiary  Guarantors,  the Note  Registrar  or the


                                       74


Trustee, or any agent of any of them, shall be held accountable by reason of the
disclosure  of any  information  as to the names and addresses of the Holders in
accordance with Section 312 of the TIA, regardless of the source from which such
information was derived,  (ii) each of such Persons shall have the protection of
Section 312(c) of the TIA and (iii) the Trustee shall not be held accountable by
reason of mailing any material  pursuant to a request made under Section  312(b)
of the TIA.

     6.2 REPORTS BY TRUSTEE.

     Within 60 days after May 15th of each year commencing with May 15th,  2005,
the Trustee will  transmit by mail to the Holders,  as their names and addresses
appear in the Note Register,  a brief report dated as of such in accordance with
and to the extent  required  under  Section  313(a) of the TIA. The Trustee will
also comply with Sections 313(b) and 313(c) of the TIA.

     The Company will promptly notify the Trustee in writing if the Notes become
listed on any stock exchange or automatic  quotation system and of any delisting
thereof.

     A copy of each Trustee's  report,  at the time of its mailing to Holders of
Notes,  will be mailed to the  Company  and filed with the  Commission  and each
stock  exchange or automatic  quotation  system,  if any, on which the Notes are
listed or quoted, as the case may be.

     6.3 REPORTS BY COMPANY.

     The Company will:

     (a) file with the Trustee,  within 30 days after the Company is required to
file the same with the  Commission,  copies  of the  annual  reports  and of the
information,  documents  and other reports (or copies of such portions of any of
the foregoing as the Commission  may from time to time by rules and  regulations
prescribe)  which  the  Company  may be  required  to file  with the  Commission
pursuant to Section 13 or Section  15(d) of the Exchange Act; or, if the Company
is not required to file information,  documents or reports pursuant to either of
said  Sections,  then the Company will file with the Trustee  such  information,
documents or reports as required pursuant to Section 9.9 hereof;

     (b) file with the Trustee and the Commission,  in accordance with rules and
regulations  prescribed  from time to time by the  Commission,  such  additional
information,  documents  and reports with respect to  compliance  by the Company
with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations; and

     (c)  transmit  by mail to all  Holders,  in the  manner  and to the  extent
provided  in  Section  313(c) of the TIA,  such  summaries  of any  information,
documents and reports (without exhibits except to the extent required by Section
313(c) of the TIA) required to be filed by the Company pursuant to paragraph (i)
or (ii)  of  this  Section  6.3 as may be  required  by  rules  and  regulations
prescribed from time to time by the Commission.

     (d)  Delivery of such  reports,  information  and  documents to the Trustee
pursuant  to  this  Section  6.3 is for  informational  purposes  only  and  the
Trustee's  receipt  of such  shall  not  constitute  constructive  notice of any


                                       75


information   contained  therein  or  determinable  from  information  contained
therein,  including the Company's compliance with any of its covenants hereunder
(as  to  which  the  Trustee  is  entitled  to  rely  exclusively  on  Officers'
Certificates).

                                   ARTICLE 7
             CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OF OR LEASE

     7.1 COMPANY MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS.

     The  Company  shall not, in any single  transaction  or a series of related
transactions,  merge or  consolidate  with or into any  other  Person,  or sell,
assign, convey, transfer, lease or otherwise dispose of all or substantially all
of  the  Properties  of  the  Company  and  its  Restricted  Subsidiaries  on  a
consolidated  basis to any other Person or group of  Affiliated  Persons  (other
than the Company and its Wholly Owned Restricted Subsidiaries),  and the Company
shall not  permit  any of its  Restricted  Subsidiaries  to enter  into any such
transaction  or  series  of  transactions  if  such  transaction  or  series  of
transactions, in the aggregate, would result in a sale, assignment,  conveyance,
transfer,  lease  or  other  disposition  of  all  or  substantially  all of the
Properties  of the Company and its  Restricted  Subsidiaries  on a  consolidated
basis to any other Person or group of Affiliated  Persons other than the Company
and its  Wholly  Owned  Restricted  Subsidiaries,  unless  at the time and after
giving effect thereto, either:

     (a) (i) either (A) if the  transaction  is a merger or  consolidation,  the
Company will be the surviving  Person of such merger or consolidation or (B) the
Person (if other than the Company)  formed by such  consolidation  or into which
the  Company  is  merged  or to  which  the  Properties  of the  Company  or its
Restricted  Subsidiaries,  as the case may be,  are  sold,  assigned,  conveyed,
transferred,  leased or  otherwise  disposed  of (any such  surviving  Person or
transferee Person being the "Surviving Entity") will be a corporation  organized
and existing  under the laws of the United States of America,  any state thereof
or the District of Columbia and will, in either case, (I) expressly  assume by a
supplemental  indenture  to  this  Indenture  and,  if the  Registration  Rights
Agreement  is then in effect,  a joinder  agreement to the  Registration  Rights
Agreement,  each  executed and  delivered to the Trustee,  in form and substance
reasonably,  satisfactory  to the Trustee,  all the  obligations  of the Company
under the Notes and this Indenture, and, if applicable,  the Registration Rights
Agreement and (II) take such actions  required  under this Indenture so that the
transaction  does not result in the surviving  Entity owning or having  acquired
Collateral  that is not  subject  to a valid  and  enforceable  perfected  first
priority  security  interest  (subject to Permitted Prior Liens) in favor of the

effect;

     (ii)  immediately  before  and  immediately  after  giving  effect  to such
transaction  or series of  transactions  on a pro forma basis (and  treating any
Indebtedness  not  previously  an  obligation  of  the  Company  or  any  of its
Restricted  Subsidiaries  which becomes the  obligation of the Company or any of
its  Restricted  Subsidiaries  in  connection  with  or  as  a  result  of  such
transaction  or  transactions  as  having  been  incurred  at the  time  of such
transaction or transactions),  no Default or Event of Default will have occurred
and be continuing;

     (iii) except in the case of the  consolidation  or merger of any Restricted
Subsidiary  with or into the Company,  immediately  after giving  effect to such
transaction or transactions on a pro forma basis, the Consolidated  Fixed Charge

     (iv) except in the case of the  consolidation or merger of the Company with
or into a Wholly Owned  Restricted  Subsidiary or of any  Restricted  Subsidiary
with or into the Company or any Wholly Owned Restricted Subsidiary,  immediately
before and immediately  after giving effect to such  transaction or transactions
on a pro forma basis (on the assumption  that the  transaction  or  transactions
occurred on the first day of the period of four full fiscal  quarters  for which
financial  statements are available ending immediately prior to the consummation
of such  transaction or  transactions,  with the  appropriate  adjustments  with
respect to the  transaction  or  transactions  being  included in such pro forma

become  subject to any Lien  (other  than a  Permitted  Lien),  the  creation or
imposition of such Lien will have been in compliance with Section 9.14 hereof;

     (vi) if the Company is not the  continuing  obligor  under this  Indenture,

satisfactory  to the Trustee,  confirmed  that its  Subsidiary  Guarantee of the
Notes will apply to the Surviving Entity's  obligations under this Indenture and
the Notes; and

     (vii)  the  Company  (or the  Surviving  Entity if the  Company  is not the
continuing obligor under this Indenture) shall have delivered to the Trustee, in
form and  substance  reasonably  satisfactory  to the Trustee,  (A) an Officers'
Certificate stating that such transaction or series of related transactions and,
if a  supplemental  indenture to this  Indenture is required in connection  with
such transaction,  such supplemental  indenture,  comply with this Indenture and
(B) an Opinion of Counsel  stating  that (I) the  requirements  of clause (i) of
this paragraph have been satisfied and (II) any  supplemental  indenture to this
Indenture or joinder agreement to the Registration Rights Agreement delivered to
the Trustee in accordance with the  requirements of this paragraph has been duly
authorized,  executed and  delivered by the Surviving  Entity or any  Subsidiary
Guarantor a party thereto and constitutes a legal,  valid and binding obligation
of the Surviving Entity and any such Subsidiary Guarantor; or

     (b) the  transaction  is effected in  compliance  with Section 9.16 hereof;
provided that all of the Notes then  Outstanding  are paid in full in accordance
with such Section 9.16 hereof;

provided that so long as the Fair Market Value of the Capital Stock of Grey Wolf
owned by the Company and its Subsidiaries does not exceed 50% of the Fair Market
Value  of  all of the  Properties  of the  Company  and  its  Subsidiaries  on a


                                       77


consolidated  basis,  then any  disposition  of all or a portion of such Capital
Stock of Grey  Wolf by the  Company  and its  Restricted  Subsidiaries  will not
constitute a sale of all or  substantially  all of the  properties and assets of
the Company and its Restricted Subsidiaries on a consolidated basis for purposes
of the covenants  described under this Article 7 or for purposes of clause (iii)
of the definition of "Change of Control" hereunder.

     (a) Upon any  consolidation  of the  Company  with or merger of the Company
into any other corporation or any sale, assignment, lease, conveyance,  transfer
or  other  disposition  of all or  substantially  all of the  Properties  of the
Company and its Restricted  Subsidiaries  on a consolidated  basis in accordance
with Section 7.1 hereof, in which the Company is not the continuing corporation,
the Surviving  Entity will succeed to, and be substituted  for, and may exercise
every right and power of, the Company under this  Indenture with the same effect
as if such  Surviving  Entity had been named as the Company  herein,  and in the
event of any such sale,  assignment,  conveyance,  transfer or other disposition
(but not a lease), the Company (which term will for this purpose mean the Person
named as the "Company" in the first paragraph of this Indenture or any successor
Person which has theretofore  become such in the manner described in Section 7.1
hereof) will be discharged of all obligations and covenants under this Indenture
and the  Notes  and  the  Company  may be  dissolved  and  liquidated  and  such
dissolution  and  liquidation  will not cause a Change of Control  under  clause
(iii)  of  the  definition  thereof  to  occur  unless  such  sale,  assignment,
conveyance,  transfer or other  disposition of all or  substantially  all of the
Properties  of the Company and its  Restricted  Subsidiaries  on a  consolidated
basis to any Person otherwise results in a Change of Control.

     (b) The Company will not permit any  Subsidiary  Guarantor  to  consolidate
with or merge with or into, or convey,  transfer or lease, in one transaction or
a series of related transactions, all or substantially all of its properties and
assets to any Person unless:

     (i) the resulting,  surviving or transferee  Person (if not such Subsidiary
Guarantor)  shall be a  Person  organized  and  existing  under  the laws of the
jurisdiction  under which such  Subsidiary  Guarantor was organized or under the
laws of the United  States of  America,  any state  thereof or the  District  of
Columbia, and such Person shall (I) expressly assume by a supplemental indenture
to this Indenture and, if the Registration Rights Agreement is then in effect, a
joinder  agreement  to the  Registration  Rights  Agreement,  each  executed and
delivered to the Trustee, in form and substance  reasonably  satisfactory to the
Trustee,  all the obligations of such Subsidiary  Guarantor under its Subsidiary
Guarantee and, if applicable,  the  Registration  Rights Agreement and (II) take
such actions  required under this Indenture,  such that the transaction does not
result in either (x) such Person owning or having  acquired  Collateral  that is
not  subject  to a valid  and  enforceable  perfected  first  priority  security
interest  (subject to Permitted Prior Liens) in favor of the Collateral Agent as
security for the Note Obligations or (y) all of the Capital Stock of such Person
owned  directly  or  indirectly  by the  Company  being duly  pledged as a first
priority  perfected  security interest (subject to Permitted Prior Liens) to the
Collateral Agent for the benefit of the holders of the Note Obligations;

                                       78


     (ii) immediately after giving effect to such transaction or transactions on
a pro forma basis (and treating any Indebtedness  which becomes an obligation of
the resulting, surviving or transferee Person as a result of such transaction as
having been issued by such Person at the time of such  transaction),  no Default
or Event of Default shall have occurred and be continuing;

     (iii)  the  Company   would  be  permitted  by  virtue  of  its  pro  forma
Consolidated  Fixed Charge  Coverage Ratio,  immediately  after giving effect to
such transaction, to Incur at least $1.00 of additional Indebtedness (other than
Permitted  Indebtedness)  under the terms of clause (1) of the first sentence of
Section 9.11 hereof; and

     (iv) the Company  delivers to the Trustee an (a) Officers'  Certificate and
an Opinion of Counsel (in form and substance satisfactory to the Trustee),  each
stating  that such  consolidation,  merger or transfer  and,  if a  supplemental
indenture to this Indenture is required in connection  with such  transaction or
transactions,  such supplemental indenture, complies with this Indenture and (b)
an Opinion of Counsel  stating that (I) the  requirements  of clause (i) of this
paragraph  have  been  satisfied  and (II) any  supplemental  indenture  of this
Indenture or joinder agreement to the Registration Rights Agreement delivered to
the Trustee in accordance with the  requirements of this paragraph has been duly
authorized,  executed and  delivered by the  resulting,  surviving or transferee
Person and  constitutes  a legal,  valid and binding  obligation of such Person;
provided,  however, that clauses (i), (iii) and (iv)(b) above shall not apply if
such transactions comply with Section 9.16 hereof and such resulting,  surviving
or transferee Person is no longer a Subsidiary of the Company.

                                       82


New York in accordance with the terms of the Notes and this Indenture.

     9.2 MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in The City of New York an office or agency where
Notes  may  be  presented  or  surrendered  for  payment,  where  Notes  may  be
surrendered  for  registration  of transfer or  exchange  and where  notices and
demands  to or  upon  the  Company  in  respect  of the  Notes,  the  Subsidiary
Guarantees and this Indenture may be served.  The Corporate  Trust Office of the
Trustee  will be such office or agency of the  Company,  unless the Company will
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

the Trustee with the address thereof,  such presentations,  surrenders,  notices
and demands may be made or served at the Corporate Trust Office, and the Company

surrenders, notices and demands.

     The Company may also from time to time  designate one or more other offices
or agencies where the Notes may be presented or surrendered  for any or all such
purposes  and may from time to time  rescind any such  designation.  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.

     9.3 MONEY FOR SECURITY PAYMENTS TO BE HELD IN TRUST.

     If the Company will at any time act as its own Paying Agent, it will, on or
before  11:00  a.m.  Eastern  Time,  on each due date of the  principal  of (and
premium,  if any,  on) or  interest on any of the Notes,  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
will 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 will have one or more Paying Agents for the Notes,  it
will on or before 11:00 a.m.  Eastern Time, on each due date of the principal of
(and  premium,  if any,  on), or interest  on, any Notes,  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 will  promptly  notify the
Trustee of such action or any failure so to act.

     The  Company  will cause each  Paying  Agent  (other  than the  Trustee) to
execute and deliver to the Trustee an instrument in which such Paying Agent will
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), interest or Liquidated Damages, if any, on Notes in trust for
the benefit of the Persons entitled thereto until such sums will be paid to such

     (b) give the  Trustee  notice of any  default by the  Company (or any other
obligor upon the Notes) 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 will be released  from all further  liability  with respect to such
sums.

     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 Note and  remaining  unclaimed  for two years after such  principal  (and
premium,  if any) or  interest  has become due and  payable  will be paid to the
Company on Company Request,  or (if then held by the Company) will be discharged
from such trust;  and the Holder of such Note will  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,  will  thereupon  cease;
provided,  however, that the Trustee or such Paying Agent, before being required
to make  any such  repayment,  may at the  expense  of the  Company  cause to be
published once, in a newspaper  published in the English  language,  customarily
published  on each  Business  Day and of general  circulation  in the Borough of
Manhattan,  The City of New York,  notice that such money remains  unclaimed and
that,  after a date specified  herein,  which will not be less than 30 days from
the date of each publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

     9.4 CORPORATE EXISTENCE.

     Except as expressly  permitted by Article 7 hereof,  Section 9.17 hereof or
other provisions of this Indenture,  the Company will 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 will not be required
to  preserve  any such  existence  of its  Restricted  Subsidiaries,  rights  or
franchises, if 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.

     9.5 PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge or cause to be paid or discharged, before
the same  will  become  delinquent,  (i) all  material  taxes,  assessments  and

Subsidiary  or upon the  income,  profits  or  Property  of the  Company  or any
Restricted  Subsidiary  and (ii) all  lawful  claims for  labor,  materials  and
supplies,  which, if unpaid, might by law become a Lien upon the Property of the


                                       84


Company or any Restricted Subsidiary;  provided,  however, that the Company will
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.

     9.6 MAINTENANCE OF PROPERTIES.

     The Company will 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  or  its  Restricted   Subsidiary's   business  may  be  properly  and
advantageously  conducted at all times; provided,  however, that nothing in this
Section will 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 9.6 will 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.

     9.7 INSURANCE

     The  Company  will 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
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.

     9.8 STATEMENT BY OFFICER AS TO DEFAULT.

     (a) The Company will  deliver to the Trustee,  within 90 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
covenant  contained  in this  Indenture  and no Default or Event of Default  has


                                       85


occurred  and is  continuing  (or,  if a Default or Event of  Default  will have
occurred,  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 will comply with Section
314(a)(4) of the TIA. For purposes of this Section 9.8(a),  such compliance will
be determined  without  regard to any period of grace or  requirement  of notice
under this Indenture.

     (b) The Company will, so long as any of the Notes are outstanding,  deliver
to the Trustee  promptly 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.

     9.9 REPORTS.

     So long as any Note is Outstanding and the Company is required by the rules
and  regulations  of the  SEC,  the  Company  will  file  with  the  SEC via the
Electronic Data Gathering and Retrieval system ("EDGAR") for public availability
(unless  the SEC  will not  accept  such a  filing),  within  the  time  periods
specified in the SEC's rules and regulations:

         o    all  quarterly  and annual  reports  that would be  required to be
              filed with the SEC on Forms 10-Q and 10-K if it were  required  to
              file such reports; and

         o    all current  reports  that the  Company  would be required to file
              with the SEC on Form 8-K if it were required to file such reports.

     The Company will also  concurrently post on its website each such report so
filed with the SEC.  The  Company  will not take any  action for the  purpose of
causing the SEC not to accept any such filings via EDGAR or otherwise.

     All such reports will be prepared in all  material  respects in  accordance
with all of the rules and  regulations  applicable to such reports.  Each annual
report  on Form  10-K  will  include  a  report  on the  Company's  consolidated
financial statements by a firm of certified independent accountants.  If, at any
time, the Company is no longer subject to the periodic reporting requirements of
the  Exchange Act for any reason or is not  otherwise  required to file with the
SEC the  reports  specified  in the first  paragraph  under this  covenant,  the
Company will instead furnish, or provide to the Trustee and cause the Trustee to
furnish at the Company's  expense,  to the Holders of the Notes the  information
required in each such report within the time period specified in the SEC's rules
and  regulations  (as if the Company  was  required to file such report with the
SEC);  provided,  however,  the  Company  will not be  required  to include  any
officer's  certification  which  would be  required to be filed as an exhibit to
such report had such report been filed with the SEC.

     The Company's  quarterly and annual financial  information  required by the
first paragraph under this covenant will include, for any period during which at
least one of its  Subsidiaries  continues to be an  Unrestricted  Subsidiary,  a
reasonably detailed presentation, either on the face of the financial statements


                                       86


or in the footnotes thereto, of the Company's financial condition and results of
operations and those of its Restricted  Subsidiaries separate from the financial
condition and results of operations of its Unrestricted Subsidiaries.

     In  addition,  the Company  agrees  that,  for so long as any Notes  remain
outstanding,  if at any time it is not required to file with the SEC the reports
specified in this first paragraph under this covenant,  the Company will furnish
to the Holders of Notes and to securities  analysts and  prospective  investors,
upon their request,  the information  required to be delivered  pursuant to Rule
144A(d)(4) under the Securities Act.

     9.10 LIMITATION ON RESTRICTED PAYMENTS.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, take the following actions:

     (i) declare or pay any dividend or make any other  payment or  distribution
(including,  without limitation,  any payment or distribution in connection with
any merger or consolidation  involving the Company or any Restricted Subsidiary)
on account of the Capital Stock of the Company or any  Restricted  Subsidiary or
to the  direct or  indirect  holders  of  Capital  Stock of the  Company  or any
Restricted  Subsidiary  in their  capacity  as such,  in each  case  other  than

transaction that does not constitute a Permitted Investment;

     (iii) make any payment to purchase, redeem, defease or otherwise acquire or
retire for value, Subordinated Indebtedness, except (1) for payment of principal
and  interest  at its  Stated  Maturity,  (2) out of a Net  Proceeds  Deficiency
following a Net  Proceeds  Offer in  accordance  with Section 9.16 hereof or (3)
upon a Change of Control to the extent (and only to the extent)  required by the
indenture or other agreement or instrument  pursuant to which such  Subordinated
Indebtedness  was issued,  provided that the Company is then in compliance  with
its  obligations  under  Section 9.15 hereof or (4) for  repayment of the Bridge
Loan Obligations in accordance with the provisions of this Indenture, the Bridge
Loan and Intercreditor Agreement (including,  without limitation,  with proceeds

or newly  issued  shares of Capital  Stock of Grey Wolf or from any other  Asset
Sale); or

     (iv) make any Investment (other than any Permitted Investment);

     (such  payments  or other  actions  described  in (but not  excluded  from)
     clauses  (i)  through  (iv) are  collectively  referred  to as  "Restricted
     Payments"),  unless at the time of and after giving  effect to the proposed
     Restricted Payment:  (1) no Default or Event of Default shall have occurred
     and be continuing (or would result therefrom),  (2) the Company could Incur
     $1.00 of additional  Indebtedness  (excluding  Permitted  Indebtedness)  in


                                       87


     accordance  with  Section  9.11 hereof,  and (3) such  Restricted  Payment,
     together  with  the  aggregate  amount  of all  other  Restricted  Payments
     declared or made after the date of this  Indenture  will not exceed the sum
     (without duplication) of the following:

            (A) 50% of the sum of (1)  Consolidated Net Income plus (2) non-cash
         asset  impairment  charges  determined  pursuant to GAAP (excluding any
         such non-cash  charge to the extent that it represents an accrual of or
         reserve for cash  expenses in any future  period) in each case  accrued
         during the period  beginning on July 1, 2004 and ending on the last day
         of the Company's  last fiscal  quarter ending prior to the date of such
         proposed Restricted Payment for which internal financial statements are
         available  (or, if such  aggregate  Consolidated  Net Income shall be a
         loss, minus 100% of such loss), plus

            (B) 100% of the aggregate Net Cash Proceeds  received by the Company

            (C) 100% of the aggregate Net Cash Proceeds  received after the date

         Stock of the  Company or any  options,  warrants  or rights to purchase
         such shares of Qualified  Capital  Stock of the Company (but  excluding
         any  debt  security  that  is  convertible  into,  or in  exchange  for
         Qualified Capital Stock of the Company), plus

            (D) 100% of the aggregate Net Cash Proceeds  received after the date
         of this Indenture by the Company (other than from any of its Restricted
         Subsidiaries)  upon the exercise of any options,  warrants or rights to
         purchase shares of Qualified Capital Stock of the Company, plus

            (E) 100% of the aggregate Net Cash Proceeds  received after the date
         of this  Indenture by the Company from the issuance or sale (other than
         to any of its Restricted  Subsidiaries) of debt securities or shares of
         Disqualified  Capital Stock that have been  converted into or exchanged
         for Qualified Capital Stock of the Company, together with the aggregate
         net cash  received  by the  Company at the time of such  conversion  or
         exchange, plus

            (F) an amount equal to the sum of (1) the aggregate  amount returned
         in  cash  or  Cash   Equivalents  to  the  Company  or  its  Restricted
         Subsidiaries  on or  with  respect  to  any  Investment  (other  than a
         Permitted  Investment)  made by the  Company  or any of its  Restricted
         Subsidiaries  subsequent  to the date of this  Indenture  in any Person
         whether through payments of interest, dividends, repayments of loans or
         advances, or other transfers or distributions of property, in an amount
         not to exceed the book value of such Investment previously made in such
         Person  that  was  treated  as  Restricted  Payments,  (2) the net cash
         proceeds  received by the Company or its restricted  Subsidiaries  from
         the disposition of all or any portion of such Investment (other than to
         a Subsidiary  of the Company) in an amount not to exceed the book value
         of such  Investment  previously made in such Person that was treated as


                                       88


         Restricted  Payments and (3) upon the  designation of any  Unrestricted
         Subsidiary as a Restricted  Subsidiary,  in an amount not to exceed the
         lesser of (x) the book value of such Investment previously made in such
         Unrestricted  Subsidiary that was treated as Restricted  Payments,  and
         (y) the fair market value of such  Unrestricted  Subsidiary,  and, with
         respect to clauses (x) and (y) of this clause (3), after  deducting any
         Indebtedness of the Unrestricted Subsidiary so designated (and, in each
         case,  as  determined  in good faith by the Board of  Directors  of the
         Company as  evidenced by a Board  Resolution  delivered to the Trustee,
         unless  determined in good faith by the Chief Executive  Officer of the
         Company  to  not  exceed  $1,000,000  and  evidenced  by  an  Officers'
         Certificate  delivered to the Trustee,  and, if so  determined to be in
         excess of $5,000,000,  based upon an opinion or appraisal  issued by an
         independent  accounting or investment  banking firm which is nationally
         recognized in the United States, or a reputable  independent  appraisal
         or petroleum  engineering firm which is reasonably  satisfactory to the
         Trustee,  as appropriate under the  circumstances),  only to the extent
         that the sum of  clauses  (1),  (2) and (3) above  does not  exceed the
         aggregate amount of all such Investments made subsequent to the date of
         this Indenture.

     (b)  Notwithstanding  paragraph (a) above,  the Company and its  Restricted
Subsidiaries  may take the following  actions or make the following  payments so
long as (in the case of clauses (ii) through (v) and (vii) below,  no Default or
Event of Default shall have occurred and be continuing or occur as a consequence
of actions or payments set forth therein):

     (i) pay any dividend on any Capital Stock of the Company or any  Restricted
Subsidiary  within 60 days  after the date of  declaration  thereof,  if at such
declaration date such declaration  complied with the provisions of paragraph (a)
above  (and  such  payment  will be  deemed  to have  been  paid on such date of
declaration  for  purposes  of any  calculation  required by the  provisions  of
paragraph (a) above);

     (ii) repurchase, redeem, retire, defease or otherwise acquire any shares of
any class of Capital  Stock of the  Company  or any  Restricted  Subsidiary,  in
exchange  for, or out of the  aggregate  net cash  proceeds of, a  substantially
concurrent  issue and sale (other than to a Restricted  Subsidiary) of shares of
Qualified Capital Stock of the Company;

     (iii) repurchase, redeem, repay, defease or otherwise acquire or retire for
value any Subordinated Indebtedness in exchange for, or out of the aggregate net
cash  proceeds of, a  substantially  concurrent  issue and sale (other than to a
Restricted  Subsidiary) of (A) shares of Qualified  Capital Stock of the Company
or (B) Refinancing Indebtedness;

     (iv)  repurchases  by the Company of options to acquire  Capital Stock from
one or more former  officers,  directors  and employees of the Company or any of
its Subsidiaries (or any of their  authorized  representatives)  upon the death,
disability or termination of employment or directorship, as applicable, provided
that the amount paid by the Company  with respect to all such  purchases  (other
than any purchase for which  payment was made in Qualified  Capital Stock of the
Company) from and after the date of this Indenture  does not exceed  $500,000 in
the  aggregate  for so long  as any  Note  remains  outstanding,  and  provided,


                                       89


further,  that, in the case of such options to acquire Capital Stock (other than
any such option being  purchased with  Qualified  Capital Stock of the Company),
the market price of the Capital Stock for which such options are  exercisable is
at least 40% lower than the exercise price of such options;

     (v) the  repurchase  or redemption  of any  Indebtedness  in the event of a
change  of  control  in  accordance  with  provisions  similar  to the  covenant
described under Section 9.15 hereof,  provided, that, prior to or simultaneously
with such  repurchase,  the  Company  has made the  Change of  Control  Offer as
provided in such  covenant with respect to the Notes and has purchased all Notes
validly tendered for payment in connection with such Change of Control Offer;

     (vi) (A) defease or otherwise  acquire all of the Outstanding 2003 Notes on
the Closing Date and (B) redeem all of the Outstanding 2003 Notes on a date that
is no later  than 60 days  after the  Closing  Date,  and pay  related  fees and
expenses, with all the proceeds from the issuance of the Notes; and

     (vii)  other  Restricted  Payments  in an  aggregate  amount  not to exceed
$500,000 from and after the date of this Indenture.

The actions  described in clause (i) of this  paragraph  (b) will be  Restricted
Payments  that will be permitted to be taken in accordance  with this  paragraph
(b) but which will  reduce the amount  that would  otherwise  be  available  for
Restricted  Payments  under clause (iv)(C) of paragraph (a) above when declared,
(but not also when  subsequently  paid pursuant to such clause (i)). The actions
described in clauses  (iii),  (iv),  (v) and (vii) of this paragraph (b) will be
Restricted  Payments that will be permitted to be taken in accordance  with this
paragraph  (b) but which will,  except with respect to exchanges  referred to in
such clause  (iii),  reduce the amount that would  otherwise  be  available  for
Restricted  Payments  under clause  (iv)(C) of paragraph (a) above.  The actions
described  in  clause  (ii) of  this  paragraph  (b),  and  clause  (vi) of this
paragraph (b) to the extent the actions described in such clause (vi) constitute
Restricted  Payments,  will be Restricted  Payments that will be permitted to be
taken in accordance  with this paragraph (b) and will not reduce the amount that
would  otherwise be available for  Restricted  Payments  under clause (iv)(C) of
paragraph (a) above.  The amount of all  Restricted  Payments  (other than cash)
shall be the fair  market  value on the date of the  Restricted  Payment  of the
assets or securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary,  as the case may be, pursuant to such Restricted Payment.
The fair market  value of any assets or  securities  that are  required to be so
valued under the terms of this  Indenture  shall be  determined in good faith by
the Board of  Directors  of the  Company  prior to the making of the  respective
Restricted Payment and evidenced by a Board Resolution  delivered to the Trustee
(or,  solely with respect to assets and  securities  in an amount not  exceeding
$1,000,000,  as determined in good faith by the Chief  Executive  Officer of the
Company and evidenced by an Officers'  Certificate delivered to the Trustee). If
the fair market value so determined exceeds $5,000,000,  the Board of Directors'
determination  must be based upon an opinion or  appraisal  issued  prior to the
making of the  respective  Restricted  Payment by an  independent  accounting or
investment banking firm which is nationally  recognized in the United States, or
a  reputable  independent  appraisal  or  petroleum  engineering  firm  which is
reasonably  satisfactory to the Trustee, as appropriate under the circumstances.
Not later than (i) the date upon which the Company or any Restricted  Subsidiary
makes a  Restricted  Payment  in excess  of  $1,000,000  or upon  which the last


                                       90


Restricted  Payment  of  a  series  of  related  Restricted  Payments  exceeding
$1,000,000 in the aggregate is made by the Company or any Restricted  Subsidiary
or (ii) 45 days after the end of any fiscal  quarter in which the Company or any
Restricted  Subsidiary makes Restricted  Payments in excess of $1,000,000 in the
aggregate  (excluding any Restricted Payment for which an Officers'  Certificate
has previously been delivered to the Trustee as contemplated by clause (i)), the
Company  will be  required to deliver to the  Trustee an  Officers'  Certificate
stating  that each such  Restricted  Payment is (or was)  permitted  and setting
forth the basis upon which the required  calculations  were  computed,  together
with a copy of any such required Board  Resolution  and/or  fairness  opinion or
appraisal.

     (c) In computing Consolidated Net Income of the Company under paragraph (a)
above, (i) the Company will 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 (ii) the Company  will 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  will 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.

     9.11 LIMITATION ON INCURRENCE OF INDEBTEDNESS  AND ISSUANCE OF DISQUALIFIED
STOCK.

     The  Company  will  not,  and  will  not  permit  any  of  its   Restricted
Subsidiaries to, create,  incur, assume,  Guarantee or otherwise become directly
or indirectly liable for the payment of (collectively, "Incur") any Indebtedness
(including any Acquired  Indebtedness),  other than Permitted  Indebtedness,  or
issue any  Disqualified  Stock,  unless  (1) at the time of such event and after
giving effect thereto and the receipt and  application  of the funds  therefrom,
the Company's  Consolidated Fixed Charge Coverage Ratio for the four full fiscal
quarters immediately  preceding such event, taken as one period, would have been
at least equal to 3.00 to 1.00, determined on a pro forma basis (including a pro
forma  application  of  the  net  proceeds  therefrom)  as  if  such  additional
Indebtedness had been Incurred,  or such Disqualified  Stock had been issued, as
the case may be, at the beginning of such four-quarter period, (2) no Default or
Event of  Default  shall  have  occurred  and be  continuing  at the  time  such
Indebtedness is Incurred or such Disqualified  Stock is issued or would occur as
a consequence  of the  Incurrence of such  Indebtedness  or the issuance of such
Disqualified Stock and (3) with respect to any such Restricted Subsidiary, it is
then a Subsidiary  Guarantor and its  Subsidiary  Guarantee  then  constitutes a
legal, valid and binding obligation of such Subsidiary Guarantor.

     The amount of any Guarantees by the Company or any Restricted Subsidiary of
any Indebtedness of the Company or one or more Restricted  Subsidiaries will not
be deemed to be  Outstanding  or Incurred  for  purposes of this Section 9.11 in
addition to the amount of Indebtedness which it Guarantees.

                                       91


     Other than to the extent provided in the Intercreditor  Agreement,  neither
the  Company  nor any  Restricted  Subsidiary  will be  permitted  to Incur  any
Indebtedness or other  obligation,  including  Permitted  Indebtedness,  that is
contractually subordinated in right of payment or security (other than Permitted
Liens) to any other  Indebtedness of the Company or that Restricted  Subsidiary,
as  applicable,   unless  such  Indebtedness  is  also  expressly  contractually
subordinated  in right of payment and security  (other than Permitted  Liens) to
the  Notes  or the  Subsidiary  Guarantee  of  that  Restricted  Subsidiary,  as
applicable,  on  substantially  identical  terms;  provided,  however,  that  no
Indebtedness  of the Company or any Restricted  Subsidiary  will be deemed to be
contractually  subordinated  in  right  of  payment  or  security  to any  other
Indebtedness  of the Company or that Restricted  Subsidiary  solely by virtue of
being  unsecured,  and the  provisions  of this  Section 9.11 shall not prohibit
tranches of Indebtedness  under the Revolving Credit Facility being subordinated
to other tranches of Indebtedness thereunder.

     9.12 LIMITATION ON GUARANTEES OF  INDEBTEDNESS  BY  SUBSIDIARIES  and other
affiliates

     (a) The Company will not permit any Subsidiary of the Company that is not a
Subsidiary Guarantor to Guarantee the payment of any Indebtedness of the Company
or any of the  Restricted  Subsidiaries  other than the Notes  unless:  (1) such
Subsidiary   simultaneously   (A)   executes  and  delivers  to  the  Trustee  a
supplemental  indenture  to  this  Indenture  and,  if the  Registration  Rights
Agreement  is then in effect,  a joinder  agreement to the  Registration  Rights
Agreement,  each in form and substance  reasonably  satisfactory to the Trustee,
providing  for such  Subsidiary  to become a  Subsidiary  Guarantor  under  this
Indenture and a party to the  Registration  Rights Agreement and (B) delivers to
the Trustee an opinion of counsel, in form and substance reasonably satisfactory
to the  Trustee,  to the effect  that such  supplemental  indenture  and joinder
agreement have been duly  authorized,  executed and delivered by such Subsidiary
and constitute legal, valid and binding  obligations of such Subsidiary;  (2) if
such  Subsidiary is a Restricted  Subsidiary,  all  properties and assets of the
kind constituting Collateral then owned by such Subsidiary shall be subject to a
valid,  enforceable  perfected  first  priority  security  interest  (subject to
Permitted Prior Liens) in favor of the Collateral Agent as security for the Note
Obligations;  and (3) such Subsidiary waives and agrees not to claim or take the
benefit or advantage of, in any manner whatsoever,  any rights of reimbursement,
indemnity  or  subrogation  or any  other  rights  against  the  Company  or any
Restricted  Subsidiary as a result of any payment by such  Subsidiary  under its
Subsidiary  Guarantee until such time as the obligations  Guaranteed thereby are
paid in full;  provided  that  this  paragraph  shall not be  applicable  to any
Guarantee  by any  Subsidiary  of the Company  that (x) existed at the time such
Person became a Subsidiary of the Company and (y) was not Incurred in connection
with, or in contemplation  of, such Person becoming a Subsidiary of the Company.
Any  Subsidiary  Guarantee  entered into by a Subsidiary  of the Company will be

the creation of such  Subsidiary  Guarantee of the Notes,  except a discharge or
release by or as a result of payment under any such Guarantee.

     (b) The Company  will not permit any of its other  Affiliates  to Guarantee
the payment of any  Indebtedness  of the Company or the Restricted  Subsidiaries

delivers to the Trustee a  supplemental  indenture to this Indenture and, if the
Registration  Rights  Agreement  is then in effect,  a joinder  agreement to the
Registration   Rights   Agreement,   each  in  form  and  substance   reasonably


                                       92


satisfactory to the Trustee,  providing for such Affiliate to become a guarantor
of the  Notes  under  this  Indenture  and a party  to the  Registration  Rights
Agreement  and (B)  delivers to the  Trustee an opinion of counsel,  in form and
substance  reasonably  satisfactory  to the  Trustee,  to the  effect  that such
supplemental indenture and joinder agreement have been duly authorized, executed
and  delivered  by such  Affiliate  and  constitute  legal,  valid  and  binding
obligation of such  Affiliate;  and (2) such Affiliate  waives and agrees not to
claim or take the benefit or advantage of, in any manner whatsoever,  any rights
of  reimbursement,  indemnity or  subrogation  or any other  rights  against the
Company  or any  Restricted  Subsidiary  as a  result  of any  payment  by  such
Affiliate  under its  Guarantee  until such time as the  obligations  Guaranteed
thereby are paid in full.

     (c)  Notwithstanding  clauses (a) and (b) above and the other provisions of
this Indenture,  any Subsidiary  Guarantee  Incurred by a Restricted  Subsidiary
pursuant  to  this  Section  9.12  will  provide  by its  terms  that it will be
automatically  and  unconditionally  released and discharged  upon the terms and
conditions set forth in Section 13.3 hereof.

the government of such foreign  jurisdiction or individual or corporate citizens
of such foreign jurisdiction in order for such Restricted Subsidiary to transact
business  in  such  foreign  jurisdiction,  (c) a sale  of  Capital  Stock  of a
Restricted  Subsidiary  effected in accordance with Sections 9.10, 9.11 and 9.16
hereof  and  only  if,  immediately  after  giving  effect  to such  sale,  such

shares of Capital Stock  represents  less than a majority of the Voting Stock of
such Restricted Subsidiary.

     9.14 LIMITATION ON LIENS.

     The  Company  will not and will not permit any  Restricted  Subsidiary  to,
directly or indirectly,  Incur or suffer to exist, or become effective, any Lien
of any kind whatsoever, except for Permitted Liens, upon any of their respective


                                       93


Properties, whether owned prior to or acquired after the date of this Indenture,

     9.15 PURCHASE OF SECURITIES UPON CHANGE OF CONTROL.

     (a) Upon the  occurrence of a Change of Control,  each Holder of Notes will
have the right to require  the Company to  repurchase  all or any part (equal to
$1,000 or an integral multiple thereof) of such holder's Notes,  pursuant to the

accrued and unpaid  interest  and  Liquidated  Damages,  if any (the  "Change of
Control  Purchase  Price"),  to the date of  purchase  (the  "Change  of Control

Offer  upon a Change  of  Control  if a third  party  makes  the an offer to the
Holders  of the Notes to  purchase  the  Notes at the same or a higher  purchase
price,  at the same  times and  otherwise  in  substantial  compliance  with the
requirements  applicable  to a Change of Control  Offer made by the  Company and

Control  Notice")  prepared  by  the  Company   describing  the  transaction  or
transactions that constitute the Change of Control and stating:

     (i) that a Change of Control has occurred and a Change of Control  Offer is
being made  pursuant to this  Section  9.15,  and that all Notes that are timely
tendered and not withdrawn will be accepted for payment;

     (ii) the Change of Control Purchase Price and the Change of Control Payment
Date,  which date will be a Business  Day no earlier  than 30 calendar  days nor
later than 60 calendar days subsequent to the date such notice is mailed;

     (iii) that any Notes or  portions  thereof not  tendered  or  accepted  for
payment will continue to accrue interest;

     (iv) that,  unless the  Company  defaults  in the  payment of the Change of
Control  Purchase  Price with  respect  thereto,  all Notes or portions  thereof
accepted  for  payment  pursuant  to the Change of  Control  Offer will cease to
accrue interest from and after the Change of Control Payment Date;

     (v)  that  any  holder  electing  to have any  Notes  or  portions  thereof
purchased  pursuant to a Change of Control  Offer will be required to  surrender
such Notes,  with the form to elect  purchase  by the  Company  pursuant to this
Section  9.15  completed,  to the Paying  Agent at the address  specified in the
notice,  prior to the close of business on the third  Business Day preceding the
Change of Control Payment Date;

     (vi) that any holder  will be entitled  to  withdraw  such  election if the
Paying  Agent  receives,  not later  than the close of  business  on the  second
Business  Day  preceding  the  Change  of  Control  Payment  Date,  a  facsimile
transmission  or letter,  setting  forth the name of the holder,  the  principal


                                       94


amount of Notes  delivered  for  purchase  and a  statement  that such holder is
withdrawing  such  holder's  election  to have such  Notes or  portions  thereof
purchased pursuant to the Change of Control Offer;

     (vii) that any holder  electing  to have Notes  purchased  pursuant  to the
Change of Control Offer must specify the principal amount that is being tendered
for  purchase,  which  principal  amount must be $1,000 or an integral  multiple
thereof;

     (viii) if Definitive  Notes have been issued  pursuant to Section 2.5, that
any holder of Definitive  Notes whose  Definitive Notes are being purchased only
in part will be issued new  Definitive  Notes equal in  principal  amount to the
unpurchased  portion of the  Definitive  Notes  surrendered,  which  unpurchased
portion  will be equal in  principal  amount to $1,000 or an  integral  multiple
thereof; and

     (ix) any other  information  necessary to enable any holder to tender Notes
and to have such Notes purchased pursuant to this Section 9.15.

     (c) On the Change of Control  Payment Date, the Company will, to the extent
lawful:  (i) accept for payment all Notes or portions thereof properly  tendered
pursuant  to the Change of Control  Offer;  (ii)  irrevocably  deposit  with the
Paying Agent, by 11:00 a.m. Eastern Time, on such date, in immediately available
funds, an amount equal to the Change of Control Purchase Price in respect of all
Notes  or  portions  thereof  so  accepted;  and  (iii)  deliver  or cause to be
delivered  to the  Trustee  the Notes so  accepted  together  with an  Officers'
Certificate  stating the aggregate principal amount of Notes or portions thereof
being  purchased by the Company.  The Paying Agent will  promptly  mail,  in the
manner provided in Section 14.5, to each holder of Notes or portions  thereof so
accepted  the  Change  of  Control  Purchase  Price for such  Notes or  portions
thereof. The Company will publicly announce the results of the Change of Control
Offer on or as soon as practicable after the Change of Control Payment Date. For
purposes of this Section 9.15, the Trustee will act as the Paying Agent.

     (d) Upon surrender and  cancellation of a Definitive Note that is purchased
in part pursuant to the Change of Control Offer, the Company will promptly issue
and the Trustee will  authenticate  and mail (or cause to be transferred by book
entry) to the surrendering  Holder of such Definitive Note a new Definitive Note
equal  in  principal  amount  to any  unpurchased  portion  of  the  surrendered
Definitive Note, if any;  provided that each such new Definitive Note will be in
a principal amount of $1,000 or an integral multiple thereof.

     (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 connection with a change of Control Offer. To the
extent that the provisions of any securities  laws or regulations  conflict with
the  provisions  of this  Section  9.15,  the  Company  shall  comply  with  the
applicable  securities  laws and  regulations  and will  not be  deemed  to have
breached its obligations under this Indenture by virtue thereof.

     (f) The Company  shall not and shall not permit any  Restricted  Subsidiary
to, create any restriction that materially impairs the ability of the Company or
such  Restricted  Subsidiary  to make a Change  of  Control  Offer or to pay the
Change of Control  Price to holders  of the Notes,  other than the  restrictions


                                       95


contained in the Intercreditor  Agreement, the Revolving Credit Facility and the
Bridge  Loan.  If a Change  of  Control  occurs at a time  when the  Company  is
contractually  prohibited from purchasing Notes, and it were unable to eliminate
this prohibition,  it would not be permitted to purchase Notes In such case, the
Company's  failure to  purchase  tendered  Notes  would  constitute  an Event of
Default under this Indenture that would, in turn, constitute a default under the
Revolving Credit Facility and the Bridge Loan.

     9.16 LIMITATION OF ASSET SALES.

     (a) The Company will not, and will not permit any Restricted Subsidiary to,
directly or  indirectly,  consummate  any Asset Sale unless:  (i) the Company or
such Restricted Subsidiary, as the case may be, receives aggregate consideration
at the time of such Asset Sale at least  equal to the Fair  Market  Value of the
assets or Capital Stock sold or otherwise disposed of pursuant to the Asset Sale
(as  determined  in good  faith by the Board of  Directors  of the  Company  and
evidenced by a Board Resolution delivered to the Trustee or, solely with respect
to Asset Sales in an amount not  exceeding  $1,000,000,  as  determined  in good
faith  by the  Chief  Executive  Officer  of the  Company  and  evidenced  by an
Officers' Certificate  delivered to the Trustee);  (ii) at least 80% of the fair
market  value of the  consideration  received by the  Company or the  Restricted
Subsidiary,  as the case may be, in respect of such Asset Sale (as determined in
good faith by the Board of  Directors  of the Company and  evidenced  by a Board
Resolution delivered to the Trustee or, solely with respect to Asset Sales in an
amount  not  exceeding  $1,000,000,  as  determined  in good  faith by the Chief

delivered to the Trustee)  consists of cash, Cash Equivalents or properties used
in the Oil and Gas Business of the Company or its Restricted Subsidiaries; (iii)
in the case of a Sale of Collateral, the Collateral Agent is immediately granted
a perfected first priority  security interest (subject to Permitted Prior Liens)
in the Net Cash  Proceeds  and  other  consideration  therefor  received  by the
Company  or the  Restricted  Subsidiary,  as the  case  may  be,  as  additional
Collateral  under the  Collateral  Documents to secure the Secured  Obligations,
and, in the case of Net Cash Proceeds,  such Net Cash Proceeds  must,  except as
otherwise  provided in the Intercreditor  Agreement,  be deposited into an Asset
Sale  Proceeds  Account,  all on terms and pursuant to  arrangements  reasonably
satisfactory to the Collateral Agent in its reasonable  determination (which may
include,  at the Collateral  Agent's  reasonable  request,  customary  Officers'
Certificates  and legal  opinions),  and the  Intercreditor  Agreement and other
Collateral  Documents include release provisions  requiring the Collateral Agent
to release deposits in an Asset Sale Proceeds Account as necessary to permit the
Company or its  Restricted  Subsidiaries  to apply such Net Cash Proceeds in the
set forth in paragraph (b) of this Section  9.16,  unless the  Collateral  Agent
shall have  received  written  notice  that a Default  or Event of  Default  has
occurred  and is  continuing;  (iv) if the  Board of  Directors  of the  Company
determines  in accordance  with either clause (i) or (ii) of this  paragraph (a)
that the Fair Market Value of the assets or Capital  Stock,  as the case may be,
to be sold or  otherwise  disposed  of  pursuant  to the Asset  Sale or the Fair
Market Value of the  aggregate  consideration  to be received by the Company and
the Restricted Subsidiaries in respect of the Asset Sale exceeds $5,000,000, the
Company shall have delivered to the Trustee an opinion or appraisal with respect
to such determination issued by an independent  accounting or investment banking
firm  which is  nationally  recognized  in the  United  States,  or a  reputable
independent   appraisal  or  petroleum  engineering  firm  which  is  reasonably
satisfactory to the Trustee, as appropriate under the circumstances; and (v) the
Company shall have delivered to the Trustee an Officers' Certificate  certifying


                                       96


that such Asset Sale  complies  with clauses (i),  (ii),  (iii) and (iv) of this
Section 9.16(a);  provided,  that (a) any Asset Sale pursuant to a condemnation,
appropriation   or  other  similar   taking,   including  by  deed  in  lieu  of
condemnation,  or pursuant to the  foreclosure  or other  enforcement  of a Lien
incurred  not in  violation  of  this  Indenture  or  exercise  by  the  related
lienholder  of rights with respect  thereto,  including by deed or assignment in
lieu of foreclosure, will not be required to satisfy the conditions set forth in
clauses (i),  (ii) and (iv) of this  paragraph  (and the  Officers'  Certificate
described in clause (v) of this  paragraph will not be required to certify as to
compliance  with such  clauses  (i),  (ii) and  (iv));  and (b) any  Asset  Sale
undertaken  by the Company or a Restricted  Subsidiary  at the  direction of the
Bridge Loan  Administrative  Agent in accordance with the terms of paragraph (c)
of this Section 9.16 shall not be required to satisfy any of the  conditions  of
this  paragraph  (a), but shall instead be required to fulfill the conditions of
such  paragraph  (c). The amount  (without  duplication)  of any  Unsubordinated
Indebtedness  of the  Company or any  Restricted  Subsidiary  that is  expressly
assumed by the transferee in an Asset Sale and with respect to which the Company
or such Restricted Subsidiary, as the case may be, is unconditionally discharged
by the  holder of such  Unsubordinated  Indebtedness,  will be deemed to be Cash
Equivalents  for purposes of clause (ii) of this paragraph (a) and shall also be
deemed to constitute a repayment of, and a permanent reduction in, the amount of
such  Unsubordinated  Indebtedness for purposes of paragraph (b) of this Section
9.16.

     (b) If the Company or any Restricted  Subsidiary  consummates an Asset Sale
(other than (i) any Asset Sale  undertaken  at the  direction of the Bridge Loan
Administrative  Agent or (ii) any Asset Sale with  respect  to Capital  Stock of
Grey  Wolf,  which,  so  long  as any  of the  Bridge  Loan  Obligations  remain
outstanding,  will be exclusively  applied to repay such outstanding Bridge Loan
Obligations  pursuant  to the terms of the  Bridge  Loan) or (iii)  there is any
Event of Loss,  the  Company  or such  Restricted  Subsidiary  may at its option
either:

     (i) no more than 365 days after such Asset Sale, or date upon which any Net
Loss Proceeds are received by the Company or a Restricted  Subsidiary in respect
of such Event of Loss,  as the case may be,  apply all or any portion of the Net
Cash  Proceeds  or  Net  Loss  Proceeds,  as  applicable,   therefrom  to  repay
Indebtedness  outstanding  under the Revolving  Credit Facility (but not, unless
the Company elects to permanently  reduce the commitment  thereunder;  provided,
that,  the Company will be required to deliver an Officer's  Certificate  to the
Trustee,  within 45 days after the end of any  fiscal  quarter in which any such
Net Cash Proceeds or Net Loss Proceeds, as applicable,  are so applied,  stating
for each such application the amount of Indebtedness repaid and the date of such
repayment);

     (ii) no more than 365 days  before or after such Asset  Sale,  or date upon
which  any Net  Loss  Proceeds  are  received  by the  Company  or a  Restricted
Subsidiary  in respect of such Event of Loss, as the case may be, use all or any
part of the Net Cash Proceeds or Net Loss Proceeds,  respectively,  therefrom to
make capital expenditures or acquire properties that will be used in the Oil and
Gas Business of the Company or its Restricted Subsidiaries,  as the case may be,
provided,  however, that, if any such Capital Expenditure is made or property is
acquired  prior to the  occurrence of such Asset Sale or date upon which any Net
Loss Proceeds are received, to the extent amounts were drawn under the Revolving
Credit  Facility  to  pay  for  such  acquisition,  contemporaneously  with  the
consummation of the Asset Sale or receipt of such Net Loss Proceeds, as the case
may be, the Company shall be required to use the Net Cash Proceeds of such Asset
Sale or the Net Loss  Proceeds  of such  Event of Loss,  as the case may be,  to


                                       97


repay (but not,  unless the Company  elects,  permanently  reduce) the Revolving
Credit Facility to the extent of the amount borrowed; or

     (iii) no more than 365 days  after  such  Asset Sale or date upon which any
Net Loss  Proceeds  are received by the Company or a  Restricted  Subsidiary  in
respect  of such  Event of Loss,  as the case may be,  and at such  time when no
Bridge Loan  Obligations  are  outstanding and there is a ratio of the Company's
consolidated  PV-10 to  Consolidated  Indebtedness of at least 1.25 to 1.00, use
all or any part of the Net Cash  Proceeds  or Net Loss  Proceeds,  respectively,
therefrom  to, on one  Interest  Payment  Date  (but not more than one  Interest
Payment  Date),  pay  interest on the Notes up to the amount of the  semi-annual
interest  scheduled to be paid on such Interest  Payment Date (without regard to
any  overdue  or default  interest  that may owing as of such  Interest  Payment
Date).

     Notwithstanding  the  foregoing,  the Net  Cash  Proceeds  received  by the
Company or any Restricted  Subsidiary in respect of any disposition by it of any
Capital Stock of Grey Wolf, whether or not such disposition constitutes an Asset
Sale,  will be required to be applied first to the repayment of any  Obligations
then outstanding under the Bridge Loan and then, if any Net Cash Proceeds remain
after such  application,  such excess Net Cash Proceeds (to the extent resulting
from an Asset Sale) will be subject to the terms  described  in this  paragraph.
The  amount of such Net Cash  Proceeds  and Net Loss  Proceeds  not  applied  or
invested as  provided  in this  paragraph  (after the period  specified  in this
paragraph) shall constitute "Excess Proceeds".

     The Revolving Credit Facility will provide that if the Net Proceeds from an
Asset Sale or the Net Loss  Proceeds  from an Event of Loss are applied to repay
Indebtedness  outstanding under the Revolving Credit Facility in accordance with
clause  (i) of the  immediately  preceding  paragraph  and  the  amount  of such
Indebtedness  is not,  within 365 days of such  application,  redrawn  under the
Revolving  Credit Facility to make capital  expenditures  or acquire  properties
that will be used in the Oil and Gas  Business of the Company or its  Restricted
Subsidiaries (as certified in an Officers'  Certificate delivered to the Trustee
prior  to the end of such  365 day  period),  then,  at the end of such  365 day
period,  the lenders'  commitment  under the Revolving  Credit  Facility will be
permanently reduced on a dollar-for-dollar  basis by the amount of such Net Cash
Proceeds  or Net Loss  Proceeds,  as the case may be,  which were not so redrawn
under the Revolving  Credit Facility and if the aggregate amount of the Net Cash
Proceeds from all other previous Asset Sales, together with the aggregate amount
of all Net Loss  Proceeds  from all other  previous  Events of Loss,  which were
similarly  applied in accordance  with clause (i) of the  immediately  preceding
paragraph and not so redrawn under the Revolving Credit Facility within 365 days
of such application  equals or exceeds  $10,000,000.  If as a result of any such
reduction in the lenders'  commitment  under the Revolving Credit Facility there
is then any  Indebtedness  outstanding  thereunder in excess of such commitment,
the amount of such excess  Indebtedness will become  immediately due and payable
under the Revolving Credit Facility.

     (c)  When the  aggregate  amount  of  Excess  Proceeds  equals  or  exceeds
$5,000,000 (the "Trigger  Date"),  the Company will be required to make an offer
to purchase,  from all Holders of the Notes,  an aggregate  principal  amount of
Notes equal to such Excess Proceeds as follows:

                                       98


     (i) Not later than the 30th day  following  the Trigger  Date,  the Company
shall give to the Trustee in the manner provided in Section 14.4 hereof, and the
Company or the Trustee, at the request and at the expense of the Company,  shall
give each Holder of the Notes in the manner  provided in Section 14.5 hereof,  a
notice (a "Purchase  Notice") offering to purchase (a "Net Proceeds Offer") from
all Holders of the Notes the maximum  principal amount  (expressed as a multiple
of $1,000) of Notes that may be purchased using an amount (the "Payment Amount")
equal to such Excess  Proceeds  (subject to  proration in the event such Payment
Amount is less than the aggregate Offered Price (as hereinafter  defined) of all
Notes tendered.

     (ii) The offer  price for the Notes  will be  payable  in cash in an amount
equal to 100% of the aggregate  principal amount of the Notes tendered  pursuant
to a Net Proceeds Offer, plus accrued and unpaid interest and Liquidated Damages
thereon  to the  date  such Net  Proceeds  Offer is  consummated  (the  "Offered
Price"),  in accordance with paragraph (iv) of this Section.  To the extent that
the  aggregate  Offered Price of the Notes  tendered  pursuant to a Net Proceeds
Offer  is  less  than  the  Payment  Amount  relating  thereto  (such  shortfall
constituting a "Net Proceeds Deficiency"), the Company may use such Net Proceeds
Deficiency, or a portion thereof, for general corporate purposes, subject to the
limitations of Section 9.10 hereof.

     (iii) If the  aggregate  Offered  Price of Notes  validly  tendered and not
withdrawn by Holders thereof  exceeds the Payment Amount,  Notes to be purchased
will be selected on a pro rata basis (with  adjustments  as  appropriate so that
only Notes in denominations of $1,000 or multiples thereof will be purchased) by
the Trustee based on the aggregate  principal amount of Notes so tendered.  Upon
completion of a Net Proceeds Offer,  the amount of Excess Proceeds will be reset
to zero.

     (iv) The Purchase  Notice will set forth a purchase date (the "Net Proceeds
Payment  Date"),  which  will be on a Business  Day no earlier  than 30 days nor
later than 60 days from the Trigger  Date.  The Purchase  Notice will also state
(1) that a Trigger  Date with  respect to one or more Asset Sales has  occurred,
that a Net  Proceeds  Offer is being made and that such  Holder has the right to
require the  Company to  repurchase  such  Holder's  Notes at the Offered  Price
subject to the limitations  described in the foregoing  paragraph (iii), (2) any
information  regarding such Net Proceeds Offer required to be furnished pursuant
to Rule  14e-1  under  the  Exchange  Act  and any  other  securities  laws  and
regulations  thereunder,  (3) that any Note, or portion thereof, not tendered or
accepted  for payment will  continue to accrue  interest,  (4) that,  unless the
Company  defaults in depositing  money with the Paying Agent in accordance  with
the last  paragraph of clause (iv) of this Section 9.16, or payment is otherwise
prevented,  any Note, or portion  thereof,  accepted for payment pursuant to the
Net Proceeds Offer will cease to accrue interest from and after the Net Proceeds
Payment Date, and (5) the instructions a Holder must follow in order to have his
Notes repurchased in accordance with paragraph (iv) of this Section.

     (d) Holders electing to have Notes or portions thereof  purchased  pursuant
to the Net Proceeds Offer will be required to surrender such Notes to the Paying
Agent at the address  specified  in the  Purchase  Notice  prior to the close of
business on the third Business Day the Net Proceeds  Payment Date.  Holders will
be entitled to withdraw their election if the Paying Agent  receives,  not later
than the close of business on the second  Business Day the Net Proceeds  Payment
Date, a facsimile  transmission  or letter setting forth the name of the Holder,
the  principal  amount of the Notes  delivered  for purchase by the Holder as to


                                       99


which his  election  is to be  withdrawn  and a  statement  that such  Holder is
withdrawing  his  election  to have such  Notes or  portions  thereof  purchased
pursuant to the Net Proceeds Offer.  Holders of Definitive Notes whose Notes are
purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered,  which unpurchased portion will be
equal to $1,000 or an integral multiple thereof.

     On the Net Proceeds  Payment Date,  the Company will, to the extent lawful,
(1) accept for payment all Notes or portions thereof validly  tendered  pursuant
to the Net Proceeds Offer in an aggregate  principal amount equal to the Payment
Amount or such  lesser  amount of Notes as has been  tendered,  (2)  irrevocably
deposit with the Paying Agent by 11:00 a.m. Eastern Time,  immediately available
funds  sufficient to pay the Purchase Price of all Notes or portions  thereof so
tendered in an aggregate  principal  amount equal to the Payment  Amount or such
lesser  amount and (3) deliver or cause to be delivered to the Trustee the Notes
so accepted.  The Paying Agent will  promptly  send,  in the manner  provided in
Section 14.5, to Holders of the Notes so accepted  payment in an amount equal to
the Net  Proceeds  Offer  Purchase  Price,  and the Company will execute and the
Trustee  will  authenticate  and mail or make  available  for  delivery  to such
Holders a new Note equal in principal  amount to any unpurchased  portion of the
Note which any such  Holder did not  surrender  for  purchase.  Any Notes not so

     (e) Except for the Intercreditor  Agreement, the Revolving Credit Facility,
and the Bridge Loan,  the Company  will not, and will not permit any  Restricted
Subsidiary  to, enter into or suffer to exist any agreement that would place any
restriction  of any kind (other than pursuant to law or regulation) on the right
of the  Company to make a Net  Proceeds  Offer  following  any Asset  Sale.  The
Company will be required to comply with the requirements of Rule 14e-1 under the
Exchange  Act and any  other  securities  laws and  regulations  thereunder,  if
applicable,  in the event that an Asset Sale  occurs and the Company is required
to purchase  Notes as  described in this  Section  9.16.  To the extent that the
provisions of any securities  laws or  regulations  conflict with the provisions
relating to the Net Proceeds Offer,  the Company will comply with the applicable
securities  laws and  regulations  and will not be deemed to have  breached  its
obligations under this Section 9.16 by virtue thereof.

Restricted  Subsidiary,  (ii) with respect to a transaction or series of related

in any material respect than such existing agreement as in effect on the Closing
Date, (3) for so long as Grey Wolf is a Subsidiary of the Company,  transactions
consummated pursuant to the corporate services agreement between the Company and
Grey Wolf,  including any amendment to, or replacement of, such agreement to the

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

     Redemption  of  Notes at the  election  of the  Company  or  otherwise,  as
permitted  or  required  by any  provision  of this  Indenture,  will be made in
accordance with such provision and, the extent applicable, this Article 10.

     10.3 ELECTION TO REDEEM; NOTICE TO TRUSTEE.

     The  election of the Company to redeem any Notes  pursuant to Section  10.1
hereof will be evidenced by a Board Resolution. In case of any redemption at the
election  of the  Company,  the  Company  will,  at least  60 days  prior to the
Redemption  Date  fixed  by  the  Company  (unless  a  shorter  notice  will  be
satisfactory to the Trustee),  notify the Trustee of such Redemption Date and of
the  principal  amount of Notes to be redeemed  and will  deliver to the Trustee
such documentation and records as will enable the Trustee to select the Notes to
be redeemed  pursuant to Section 10.4 hereof.  Any election to redeem Notes will
be revocable until the Company gives a notice of redemption  pursuant to Section
10.5 hereof to the Holders of Notes to be redeemed.

     10.4 SELECTION BY TRUSTEE OF NOTES TO BE REDEEMED.

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

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

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

     10.5 NOTICE OF REDEMPTION.

                                      104


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

     All notices of redemption will state:

     (a) the Redemption Date;

     (b) the Redemption Price;

     (c)  if  less  than  all  Outstanding   Notes  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
and unpaid  interest and  Liquidated  Damages,  if any, to the  Redemption  Date
payable as provided in Section  10.7  hereof)  will become due and payable  upon
each such Note, or the portion  thereof,  to be redeemed,  and that,  unless the
Company  defaults  in the  payment of the  Redemption  Price and any  applicable
accrued interest, interest thereon will cease to accrue on and after said date;

     (e) the place or places where such Notes are to be surrendered  for payment
of the Redemption Price; and

     (f) the CUSIP number, if any.

     Notice of redemption of Notes to be redeemed at the election of the Company
will 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 Notes or any defect therein will not affect the validity of any
proceedings for the redemption of other Notes.

     10.6 DEPOSIT OF REDEMPTION PRICE.

     On or before 11:00 a.m.  Eastern Time, on any Redemption  Date, the Company
will  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 10.3 hereof) an amount of money  sufficient to pay the Redemption  Price
of, and accrued and unpaid  interest  on, all the Notes which are to be redeemed
on such Redemption Date.

     10.7 NOTES PAYABLE ON REDEMPTION DATE.

     Notice of  redemption  having been given as  aforesaid,  the Notes so to be
redeemed will, 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  will
default in the payment of the Redemption  Price and accrued and unpaid interest)
such Notes  will cease to bear  interest.  Upon  surrender  of any such Note for
redemption in accordance with said notice, such Note will be paid by the Company
at the Redemption Price,  together with accrued and unpaid interest,  if any, to
the Redemption  Date;  provided,  however,  that  installments of interest whose


                                      105


Stated  Maturity  is on or prior to the  Redemption  Date will be payable to the
Holders of such Notes, or one or more Predecessor  Notes,  registered as such at
the close of business on the relevant  Record Dates according to their terms and
the provisions hereof.

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

     10.8 NOTES REDEEMED IN PART.

         Any Note which is to be redeemed only in part will be surrendered at
the office or agency of the Company maintained for such purpose pursuant to
Section 10.2 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 will execute, and the
Trustee will authenticate and deliver to the Holder of such Note without service
charge, a new Note or Notes 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 Note so surrendered.

Intercreditor Agreement and the other Collateral Documents to which such Persons

Company further covenants and agrees that the  Intercreditor  Agreement and each
of the  Collateral  Documents,  as  applicable,  creates  or will  create  (when
delivered) a shared first priority  perfected  security  interest (to the extent


                                      106


attainable by filing,  recordation or possession, and subject to Permitted Prior

have  reasonably  known of any such deficiency with respect to any such property
or asset:

         (1)  execute and deliver to the  Collateral  Agent one or more  joinder
     agreements to the  applicable  Collateral  Documents and any other security

     Collateral in favor of the Collateral  Agent for the benefit of the holders
     of the Note Obligations;

         (2)  deliver  to the  Collateral  Agent  and  the  Trustee  one or more
     Opinions of Counsel reasonably satisfactory to the Collateral Agent and the

     Liens) in favor of the Collateral Agent,  including by pledging any Capital
     Stock  constituting  such Collateral as  appropriate,  and cause each other
     Lien upon such  Collateral  to be (a)  released,  unless it is a  Permitted
     Prior Lien, or (b) subordinated,  whether by agreement or operation of law,
     to the  Collateral  Agent's  Liens for the  benefit  of holders of the Note
     Obligations if it is a Permitted Lien but not a Permitted Prior Lien; and

         (4)  deliver  to the  Collateral  Agent  and  the  Trustee  one or more
     Opinions of Counsel reasonably satisfactory to the Collateral Agent and the
     Trustee  with  respect to lien  perfection  matters set forth in clause (3)

cause, at the Company's expense, each Collateral Document, and all amendments or
supplements  thereto,  to be registered,  recorded and filed and/or  re-recorded

     Subject to the provisions of the Intercreditor Agreement, the Trustee shall
have power to institute in its name and to maintain  such suits and  proceedings
as it may deem expedient to prevent any impairment of the Collateral by any acts
which may be unlawful or in violation of this Indenture or any of the Collateral
Documents,  and such suits and  proceedings as the Trustee may deem expedient to
preserve  or protect  its  interests  and the  interests  of the  Holders in the
Collateral and in the principal,  interest, issues, profits, rents, revenues and
other income arising therefrom,  including power to institute and maintain suits
or proceedings to restrain the enforcement of or compliance with any legislative
or other governmental  enactment,  rule or order that may be unconstitutional or
otherwise  invalid,  if the enforcement of, or compliance  with, such enactment,
rule or order would impair the security under any of the  Collateral  Documents,
or be prejudicial  to the interests of the Holders or the Trustee.

     11.5 Release of Collateral.

     (a) The Trustee shall not at any time release,  or authorize the Collateral
Agent or any other Person to release,  Collateral  from the Liens created by the
Collateral Documents unless such release is in accordance with the provisions of
this Indenture and the Collateral Documents.

     (b) The release of any Collateral from the Lien of the Collateral Documents
shall not be deemed to impair the security under this Indenture in contravention
of the  provisions  hereof  if and to the  extent  the  Collateral  is  released
pursuant  to  this  Indenture  and  the  Collateral  Documents.  To  the  extent
applicable,  the Company shall comply with Section 314(d) of the TIA relating to
the release of property from the Lien of the  Collateral  Documents and relating
to the substitution  therefor of any property to be subjected to the Lien of the
Collateral  Documents.  Any certificate or opinion required by Section 314(d) of
the TIA may be made by an Officer of the Company,  except in cases where Section
314(d)  of the TIA  requires  that such  certificate  or  opinion  be made by an


                                      108


independent person, which person shall be an independent engineer,  appraiser or
other expert selected by the Company.

     11.6 Specified Releases of Collateral.

     (a) Satisfaction and Discharge;  Defeasance. The Company and the Restricted
Subsidiaries  shall be entitled to obtain a full release of the Collateral  from
the Liens of the Collateral  Documents with respect to the Note Obligations upon
payment in full of all principal,  premium, if any, interest on the Notes and of
all other  Obligations  for the payment of money due and owing to the Trustee or
the Holders under this Indenture,  the Notes,  the Guarantees and the Collateral
Documents, or upon compliance with the conditions precedent set forth in Article
12 hereof for Legal Defeasance or Covenant Defeasance. Upon such payment or upon
delivery  by the  Company to the  Trustee  of an  Officers'  Certificate  and an
Opinion of Counsel,  each to the effect that such conditions precedent have been
complied with (and which may be the same  Officers'  Certificate  and Opinion of
Counsel required by Article 12),  together with such  documentation,  if any, as
may be required by the TIA (including, without limitation, Section 314(d) of the
TIA)  or  reasonably  required  by the  Trustee  prior  to the  release  of such
Collateral,  the Trustee  shall  forthwith  take all action that is necessary or
reasonably requested by the Company (in each case at the expense of the Company)
to release and reconvey to the Company  without  recourse all of the Collateral,
and shall  deliver such  Collateral  in its  possession to the Company and shall
execute and deliver to the Company  releases and  satisfactions,  in  recordable
form, to the extent reasonably requested by the Company.

     (b) Releases of Collateral in Connection with Asset Sales.  The Company and
the  Restricted  Subsidiaries  shall be entitled to obtain a release of, and the
Trustee shall release,  items of Collateral (including property and assets owned
by a  Restricted  Subsidiary  of  which  the  Capital  Stock  is  being  sold in
compliance  with the terms of this Indenture and which  following such sale will
not be a Restricted  Subsidiary),  other than  certain  Trust  Monies,  that are
subject to an Asset Sale or other  disposition  as provided  under  Section 11.7
hereof (the "Released Collateral") upon compliance with the conditions precedent
that the Company shall have  delivered to the Collateral  Agent,  with a copy to
the Trustee, the following:

     (i) a notice from the Company requesting release of Released  Collateral (a
"Company Notice") which

            (A) specifically describes the proposed Released Collateral;

            (B)  specifies  the fair market  value of such  Released  Collateral
         (which,  in the  case  of a  sale  of  Capital  Stock  of a  Restricted
         Subsidiary  resulting in it no longer  being a  Restricted  Subsidiary,
         means the fair market value of such Capital  Stock) as of a date within
         60 days of such  notice  (as  determined  in good faith by the Board of
         Directors of the Company and evidenced by a Board Resolution  delivered
         to the Collateral  Agent and the Trustee or, solely with respect to the
         Released  Collateral  in an  amount  not  exceeding  $1.0  million,  as
         determined in good faith by the Chief Executive  Officer of the Company
         and evidenced by an Officers'  Certificate  delivered to the Collateral
         Agent and the Trustee);

                                      109


            (C) states (i) that the  consideration  to be received in respect of
         such Released  Collateral is at least equal to the fair market value of
         such Released Collateral (which, in the case of a sale of Capital Stock
         of a Restricted Subsidiary resulting in it no longer being a Restricted
         Subsidiary,  means the fair market value of such Capital Stock) or (ii)
         with  respect to an  interest  in Farmout  Property to be conveyed to a
         farmee  under a Farmout  Agreement,  that such  Farmout  Agreement is a
         Permitted Farmout Agreement;

            (D) states that the release of such  Released  Collateral  shall not
         materially and adversely impair the value of the remaining  Collateral,
         taken as a whole,  or interfere with the Collateral  Agent's ability to
         realize such value and will not impair the maintenance and operation of
         the remaining Collateral, taken as a whole;

            (E)  confirms the sale or other  disposition  of, or an agreement to
         sell or otherwise  dispose of, such Released  Collateral in a bona fide
         sale to a person  that is not an  Affiliate  of the  Company or, in the
         event  that such sale or other  disposition  is to a person  that is an
         Affiliate  of  the  Company,   confirming   that  such  sale  or  other
         disposition is made in compliance with Section 9.17;

            (F)  certifies  that such  Asset  Sale or other  disposition  of the
         Released  Collateral  complies  with the terms and  conditions  of this
         Indenture  and  the   Intercreditor   Agreement,   including,   without
         limitation, Section 9.16 hereof; and

            (G) in the event that there is to be a substitution  of property for
         such  Collateral  subject  to the  Asset  Sale  or  other  disposition,
         specifies the property intended to be substituted for the Collateral to
         be sold or  disposed of and that such  property  will be subject to the
         Liens under the Collateral Documents.

     (ii) a certificate certifying that

            (A) such sale or other disposition covers only Collateral  requested
         to be released or other property which is not Collateral;

            (B)  all  Net  Cash  Proceeds,  if  any,  from  the  sale  or  other
         disposition of any of such Released Collateral will be applied pursuant
         to the provisions of this Indenture and the Intercreditor Agreement and
         other  Collateral  Documents  in  respect  of  Asset  Sales  and  other
         dispositions of Collateral to the extent applicable thereto;

            (C) there is no  Default or Event of  Default  under this  Indenture
         (and no  "default"  or "event of default"  under the  Revolving  Credit
         Facility or the Bridge Loan) in effect on the date thereof;

            (D) the release of the proposed Released  Collateral will not result
         in a Default or Event of Default  under this  Indenture (or a "default"
         or "event of default" under the Revolving Credit Facility or the Bridge
         Loan);

                                      110



(E)               the release of the proposed Released Collateral complies with
                  the TIA; and

(F)               all conditions precedent in this Indenture and the
                  Intercreditor Agreement and other Collateral Documents
                  relating to the release of the proposed Released Collateral
                  have been complied with.

     (iii) if the fair market value of such Released  Collateral  (which, in the
case of a sale of Capital  Stock of a Restricted  Subsidiary  resulting in it no
longer  being a  Restricted  Subsidiary,  means  the fair  market  value of such
Capital  Stock)  exceeds  $1,000,000  (as specified in the notice to be provided
pursuant to clause (i)(B) above),  an opinion of counsel,  in form and substance
reasonably  satisfactory to the Collateral  Agent and the Trustee,  stating that
such release is permitted  under and complies  with the terms of this  Indenture
and  the  Intercreditor   Agreement  and  other  Collateral  Documents  and  all
conditions precedent thereunder to such release have been complied with;

     (iv) if the fair market value of such Released  Collateral  (which,  in the
case of a sale of Capital  Stock of a Restricted  Subsidiary  resulting in it no
longer  being a  Restricted  Subsidiary,  means  the fair  market  value of such
Capital  Stock)  exceeds  $5,000,000  million (as  specified in the notice to be
provided  pursuant to clause (i)(B) above), an opinion or appraisal with respect
to the  determination  of  such  fair  market  value  issued  by an  independent
accounting  or  investment  banking firm which is  nationally  recognized in the
United States,  or a reputable  independent  appraisal or petroleum  engineering
firm which is reasonably  satisfactory to the Collateral  Agent and the Trustee,
as appropriate under the circumstances;

     (v) if such Released  Collateral  is an interest in Farmout  Property to be
conveyed to a farmee under a Permitted Farmout Agreement,  such certificates and
board resolutions, if any, required by the definitions of Farmout Property Value
and Permitted Farmout Agreement; and

     (vi) all documentation required by the TIA, if any, prior to the release by
the Collateral Agent of the Released  Collateral,  and, in the event there is to
be a substitution of property for such Collateral, all documentation required by
the TIA to effect the  substitution  of such new  Collateral and to subject such
new  Collateral  to valid and  enforceable  first  priority  perfected  security
interests (subject to Permitted Prior Liens) granted by the relevant  Collateral
Documents,  and all  documents  required by Section  11.1 hereof with respect to
such new Collateral.

     Upon  compliance  by the Company with the  conditions  precedent  set forth
above,  the Trustee  shall cause to be released  and  reconveyed  to the Company
without  recourse,  the Released  Collateral and shall deliver any such Released
Collateral in its possession to the Company and shall execute and deliver to the
Company at the Company's expense releases and satisfactions, in recordable form,
to the extent reasonably requested by the Company.

     (c) Releases of Collateral in Connection  with Events of Loss.  The Company
and the  Restricted  Subsidiaries  shall be entitled to obtain a release of, and
the  Trustee  shall  release,  items of  Collateral  subject to an Event of Loss
(other than Trust Monies  constituting  Net Loss  Proceeds from an Event of Loss
with respect to  Collateral,  which Trust Monies are subject to release from the


                                      111


Lien of the  Collateral  Documents  as provided  under  Article 12 hereof)  upon
compliance  with the conditions  precedent that the Company shall have delivered
to the Collateral Agent, with a copy to the Trustee, the following:

     (i) a certificate of the Company certifying that

            (A)  such  Collateral  is the  subject  of an  Event of Loss and the
         amount of the Net Loss Proceeds received in connection therewith;

            (B)  if   applicable,   that  such   property   has  been  taken  by
         Condemnation;

            (C) in the case of a taking by Condemnation,  that the award for the
         property  so taken has become  final and that an appeal from such award
         is not advisable in the interests of the Company or the Holders; and

            (D) that  all  conditions  precedent  herein  and in the  Collateral
         Documents  provided for  relating to such  release  have been  complied
         with;

Trustee.

     In any proceedings for the Condemnation of any Collateral,  the Trustee may
be represented by counsel who may be counsel for the Company.

     Upon  compliance  by the Company with the  conditions  precedent  set forth
above, the Trustee shall cause to be released and reconveyed without recourse to
the Company the Collateral which is the subject of such Event of Loss, and shall
deliver such  Collateral in its  possession to the Company and shall execute and
deliver to the Company at the Company's expense releases and  satisfactions,  in
recordable form, to the extent reasonably requested by the Company.

     11.7 Disposition of Collateral Without Release.

     Notwithstanding  the  provisions  of Sections 11.5 and Section 11.6 hereof,
the  Intercreditor  Agreement,  and the  Collateral  Documents  and  subject  to
Sections  11.8 and Section  14.10  hereof,  so long as no Event of Default under
this  Indenture  (or  "event of  default"  under  each of the  Revolving  Credit
Facility  and the Bridge  Loan)  exists or no Default or Event of Default  under
this  Indenture (or "default" or "event of default"  under each of the Revolving
Credit Facility and the Bridge Loan), would result therefrom and so long as such
transaction would not violate the  Intercreditor  Agreement and other Collateral
Documents,  the  Company  and its  Restricted  Subsidiaries  may,  to the extent
permitted  by  applicable  law,  without  any prior  release  or  consent by the
Trustee:

     (1) dispose of equipment and other assets  included in the Collateral  that
has become worn out, defective or obsolete or not used or useful in the business
of the Company or any Restricted Subsidiary and which is, to the extent required


                                      112


by the  Intercreditor  Agreement  or other  Collateral  Documents,  replaced  by
property of  substantially  equivalent or greater value which becomes subject to
the Lien of any of the  Collateral  Documents;  (2) sell,  lease or abandon  any
undeveloped  oil and gas property  subject to the Lien of any of the  Collateral
Documents  or any other oil and gas  property  subject to the Lien of any of the

for value.

     The Company shall execute and deliver to the  Collateral  Agent,  within 30
calendar days following the end of each six-month  period  beginning on December
1, 2004, a certificate  to the effect that all releases and  withdrawals  during
the  preceding  six-month  period with respect to which no release or consent of
the Collateral Agent was obtained were in the ordinary course of the business of
the  Company  and  the  Restricted  Subsidiaries  and  were  permitted  by  this
Indenture,  the  Intercreditor  Agreement and other Collateral  Documents or the
TIA.

     Nothing in this Article 11 shall limit the right of each of the Company and
the Restricted  Subsidiaries  to sell,  lease or otherwise deal in or dispose of
its property or assets that do not  constitute  Collateral,  subject only to the
provisions of Article 6 hereof.

     11.8 Sufficiency of Release.

     All  purchasers  and  grantees of any property or rights  purporting  to be
released  shall be  entitled  to rely upon any  release  executed by the Trustee
hereunder as sufficient for the purpose of this Indenture and as  constituting a
good and valid release of the property  therein  described from the Lien of this
Indenture and of the Collateral Documents.

     11.9 Actions by the Trustee.

     Subject to the provisions of the  Collateral  Documents and Article 12, the
Trustee may in its sole  discretion  and without the consent of the Holders take
all actions it deems necessary or appropriate in order to (i) enforce any of the
terms of the  Collateral  Documents  and (ii) to collect and receive all amounts
payable in respect of the  obligations of the Company and any  Guarantors  under
the Collateral Documents and this Indenture. The Trustee shall have the power to
institute and maintain such suits and  proceedings  as it may deem  expedient in
order  to  prevent  any  impairment  of the  Collateral  by any act  that may be
unlawful or in violation of this Indenture or the Collateral Documents, and such
suits and  proceedings  as the Trustee may deem expedient to preserve or protect
its  interests and those of the Holders in the  Collateral.  No duty beyond that
set forth in Section  5.1 is imposed on the  Trustee  pursuant  to this  Section
11.9.

                                      113


     The Company may, at its option by Board Resolution,  at any time, after (1)
the  penultimate  Interest Reset Date preceding the final Stated Maturity of the
Notes or (2) if applicable,  the  penultimate  Interest Reset Date preceding the
redemption  date upon which all of the  outstanding  Notes have been  called for
redemption in accordance with the terms of this Indenture,  elect to have either
Section 12.2 or Section 12.3 hereof be applied to all  Outstanding  Notes,  upon
compliance with the conditions set forth below in this Article 12.

     12.2 DEFEASANCE AND DISCHARGE.

     Upon the  Company's  exercise  under  Section  12.1  hereof  of the  option
applicable to this Section 12.2, the Company and the Subsidiary  Guarantors will
be deemed to have been discharged from their respective obligations with respect
to all  Outstanding  Notes on the date the  conditions set forth in Section 12.4
hereof are satisfied (hereinafter,  "Legal Defeasance").  For this purpose, such
Legal  Defeasance  means that the Company and the Subsidiary  Guarantors will be
deemed (i) to have paid and discharged  their respective  obligations  under the
Outstanding Notes and the Subsidiary  Guarantees;  provided,  however,  that the
Notes will  continue to be deemed to be  "Outstanding"  for  purposes of Section
12.5 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 under such
Notes and such  Subsidiary  Guarantees and this Indenture  insofar as such Notes
are  concerned  (and the Trustee,  at the expense and  direction of the Company,
will  execute  proper  instruments  acknowledging  the  same),  except  for  the
following which will survive until otherwise terminated or discharged hereunder:
(a) the rights of Holders of Outstanding Notes to receive, solely from the trust
fund  described  in  Section  12.4  hereof  and as more  fully set forth in such
Section,  payments  in respect of the  principal  of (and  premium if any,  on),
interest and  Liquidated  Damages,  if any, on such Notes when such payments are
due (or at such time as the Notes 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,
2.5, 2.6, 2.9, 2.13, 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 12),  13.4 and 13.5 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 12. Subject to compliance with this Article 12, the Company may exercise
its option  under this Section 12.2  notwithstanding  the prior  exercise of its
option under Section 12.3 hereof with respect to the Notes.

     12.3 COVENANT DEFEASANCE.

     Upon the  Company's  exercise  under  Section  12.1  hereof  of the  option
applicable to this Section 12.3, the Company and each Subsidiary  Guarantor will
be released from their respective  obligations  under any covenant  contained in
Article 9, in Sections 9.5 - 9.20 and in Section 13.2 hereof with respect to the
Outstanding  Notes on and after  the date the  conditions  set  forth  below are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes will thereafter be
deemed  not to be  "Outstanding"  for the  purposes  of any  direction,  waiver,
consent or declaration or Act of Holders (and the  consequences  of any thereof)
in connection with such covenants,  but will continue to be deemed "Outstanding"
for all other purposes  hereunder.  For this purpose,  such Covenant  Defeasance
means  that,  with  respect  to the  Outstanding  Notes,  the  Company  and each
Subsidiary  Guarantor  may omit to  comply  with and will 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


                                      114


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 will
not constitute a Default or an Event of Default under Sections  4.1(c),  4.1(d),
4.1(e),  4.1(g) hereof,  but, except as specified  above,  the remainder of this
Indenture and such Notes will be unaffected thereby.

     12.4 CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

     The following  will be the conditions to application of either Section 12.2
or 12.3 hereof to the Outstanding Notes:

     (a)  Subject  to the terms of  Article  3, the  Company  or any  Subsidiary
Guarantor must irrevocably deposit or cause to be deposited with the Trustee (or
another trustee satisfying the requirements of Section 5.7 hereof who will agree
to comply with the  provisions  of this  Article 12  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  Notes,  (A) cash in U.S.  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 will be applied by the
Trustee (or other  qualifying  trustee) to pay and discharge,  the principal of,
premium, if any, and interest and Liquidated Damages, if any, on the Outstanding
Notes  on  their  final  Stated  Maturity   thereof  (or  Redemption   Date,  if
applicable),  provided that the Trustee will have been irrevocably instructed in
writing  by the  Company  to apply  such  money  or the  proceeds  of such  U.S.
Government  Obligations to said payment with respect to the Notes. Before such a
deposit,  the Company may give to the Trustee,  in  accordance  with Section 2.3
hereof,  a notice of its  election to redeem all of the  Outstanding  Notes at a
future  date  in  accordance  with  Article  13  hereof,  which  notice  will be
irrevocable.  The Company shall specify  whether the Notes are being defeased to
maturity or to a particular Redemption Date. Such irrevocable redemption notice,
if given,  will be given effect in applying  the  foregoing.  For this  purpose,
"U.S.  Government  Obligations" means securities that are (1) direct obligations
of the United  States of America for the timely  payment of which its full faith
and credit is pledged or (2) 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 will also
include a depositary  receipt issued by a bank (as defined in Section 3(a)(2) of
the Securities  Act of 1933, as amended),  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 amount of the
holder of such  depositary  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  depositary  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
depositary receipt.

                                      115


     (b) No Event of Default with respect to the Notes will have occurred and be
continuing on the date of such deposit or, insofar as Sections 4.1(j) and 4.1(k)
are  concerned,  at any time during the period  ending on the 91st day after the
date of such deposit.

     (c) The Company must deliver to the Trustee an Opinion of Counsel,  in form
and substance  reasonably  satisfactory to the Trustee, to the effect that after
the 91st day following  the deposit,  the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency,  reorganization or similar laws
affecting creditors' rights generally.

     (d) The  Company  must  deliver  to the  Trustee an  Officers'  Certificate
stating  that  the  deposit  was not made by the  Company  with  the  intent  of
hindering,  delaying  or  defrauding,  or making  preferential  payments  to the
holders  of  Notes in lieu of  payments  to,  creditors  of the  Company  or its
Subsidiaries.

     (e) Such Legal Defeasance or Covenant Defeasance will 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.

     (f) Such  Legal  Defeasance  or  Covenant  Defeasance  will not result in a
breach or violation of, or constitute a default under any 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.

     (g) In the case of an election  under  Section 12.2 hereof the Company will
have  delivered  to the  Trustee an Opinion of  Counsel,  in form and  substance
reasonably  satisfactory  to the  Trustee,  stating  that  (a) the  Company  has
received  from, or there has been published by, the Internal  Revenue  Service a
ruling,  or (b) since the date of this Indenture  there has been a change in the
applicable federal income tax laws, in either case providing that the Holders of
the Outstanding Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Legal Defeasance and will be subject to federal
income  tax on the same  amounts,  in the same  manner  and at the same times as
would have been the case if such Legal  Defeasance  had not  occurred  (it being
understood  that (1) such Opinion of Counsel will also state that such ruling or
applicable  law is consistent  with the  conclusions  reached in such Opinion of
Counsel and (2) the Trustee will be under no obligation to investigate the basis
of correctness of such ruling).

     (h) In the case of an election under Section 12.3 hereof,  the Company will
have  delivered  to the  Trustee an  Opinion  of  Counsel in form and  substance
reasonably  satisfactory  to the Trustee,  to the effect that the Holders or the
Outstanding  Notes  will not  recognize  income 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 (in the
case of Legal  Defeasance,  such  opinion  must  refer  to and be  based  upon a
published  ruling of the  Internal  Revenue  Service  or a change in  applicable
United States federal income tax laws).

     (i) The Company will have delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel in form and substance  reasonably  satisfactory to the
Trustee,  each stating that all  conditions  precedent  provided for relating to


                                      116


either the Legal Defeasance under Section 12.2 hereof or the Covenant Defeasance
under Section 12.3 (as the case may be) have been satisfied.

     12.5 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 12.5, the  "Trustee")  pursuant to Section 12.4 hereof in respect of the
Outstanding  Notes  will  be  held in  trust  and  applied  by the  Trustee,  in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine,  to the Holders of such Notes 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  will pay and  indemnify  the Trustee  against any tax,  fee or
other charge imposed on or assessed  against the U.S.  Governmental  Obligations
deposited pursuant to Section 12.4 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 Notes.

     Anything in this  Article 12 to the contrary  notwithstanding,  the Trustee
will 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  12.4
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 12.

     12.6 REINSTATEMENT.

     If the  Trustee  or any  Paying  Agent  is  unable  to apply  any  money in
accordance  with  Section  12.5 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 Notes will be revived and  reinstated as though no
deposit had occurred  pursuant to Section  12.2 or 12.3 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 12.5 hereof;  provided,  however,  that if
the Company or any  Subsidiary  Guarantor  makes any payment of principal of (or
premium  if any,  on),  interest  or  Liquidated  Damages,  if any,  on any Note
following the  reinstatement of its obligations,  the Company or such Subsidiary
Guarantor  will be  subrogated  to the  rights of the  Holders  of such Notes to
receive such payment from the money held by the Trustee or Paying Agent.

                                   ARTICLE 13
                              SUBSIDIARY GUARANTEES

     13.1 UNCONDITIONAL GUARANTEE.

                                      117


     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 Notes  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 Notes and
that:

     (1) the principal of (and premium,  if any,  on),  interest and  Liquidated
Damages, if any, on the Notes 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 Notes,  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

     (2) in case of any  extension of time of payment or renewal of any Notes 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  to the
limitations set forth in Section 13.4 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  will, to the extent  permitted by
law be unconditional, irrespective of the validity, regularity or enforceability
of the Notes or this  Indenture,  the absence of any action to enforce the same,
any waiver or consent by any Holder of the Notes with respect to any  provisions
hereof or thereof,  the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal  or  equitable  discharge  or  defense  of a  guarantor.  Each  Subsidiary
Guarantor hereby waives, to the extent permitted by law, diligence, presentment,
demand of payment,  filing of claim 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 Notes,  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,  will be  reinstated  in full  force and  effect.  Each
Subsidiary  Guarantor  agrees it will not be  entitled  to enforce  any right of
subrogation in relation to the Holders in respect of any obligations  guaranteed
hereby  until  payment  in  full  of all  obligations  guaranteed  hereby.  Each
Subsidiary Guarantor further agrees that, as between each Subsidiary  Guarantor,
on the one hand,  and the Holders and the  Trustee,  on the other hand,  (a) the
maturity of the obligations  guaranteed hereby may be accelerated as provided in
Article 7 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 (b) in the  event  of any
acceleration  of  such  obligations  as  provided  in  Article  7  hereof,  such
obligations  (whether  or not due and  payable)  will  forthwith  become due and


                                      118


payable  by each  Subsidiary  Guarantor  for  the  purpose  of  this  Subsidiary
Guarantee.

     13.2 SUBSIDIARY GUARANTOR MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

     (a)  Except as set forth in  Article 8 hereof,  nothing  contained  in this
Indenture or in any of the Notes will prevent any  consolidation  or merger of a
Subsidiary Guarantor with or into the Company or another Subsidiary Guarantor or
will 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 8 hereof,  nothing  contained  in this
Indenture or in any of the Notes will 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  will be a party or parties,  or will 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 (a) immediately after
such transaction, and giving effect thereto, no Default or Event of Default will
have  occurred  as a result  of such  transaction  and be  continuing,  (b) such
transaction  will not violate any of the covenants of Sections 9.1 - 9.20 hereof
and (c) 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 13 and in
a notation to the Notes, 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,  will  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 will have merged, or by the Person that will have
acquired  such Property  (except to the extent the following  Section 13.3 would
result in the release of such Subsidiary Guarantee, in which case such surviving
Person  or  transferee  of such  Property  will  not  have to  execute  any such
supplemental  indenture and will 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 will 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.

     13.3 RELEASE OF SUBSIDIARY GUARANTORS.

     Upon the sale or  disposition  (by  merger or  otherwise)  of a  Subsidiary
Guarantor (or of 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


                                      119


not limited to the  provisions  of Section  13.2 hereof or pursuant to Article 8
hereof,  such  Subsidiary  Guarantor will be deemed released from its Subsidiary
Guarantee and all related obligations under this Indenture;  provided,  however,
that any such  termination will 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 will also terminate upon such
sale or other  disposition.  The Trustee will 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 will be released from its
Subsidiary  Guarantee and all related  obligations  under this  Indenture for so
long as it remains an  Unrestricted  Subsidiary.  The  Trustee  will  deliver an
appropriate  instrument  evidencing  such  release upon its receipt of the Board
Resolution designating such Subsidiary Guarantor as an Unrestricted Subsidiary.

     Notwithstanding  any other  provision of this  Indenture,  each  Subsidiary
Guarantor will be deemed released from its respective  Subsidiary  Guarantee and
all related  obligations  under this Indenture in the event that all obligations
of such Subsidiary  Guarantor under the guarantee which resulted in the creation
of  such  Subsidiary  Guarantee  will  also  terminate,  except  a  termination,
discharge or release of such  guarantee by or as a result of, payment under such
guarantee.  The Trustee will deliver an appropriate  instrument  evidencing such
release  upon  receipt  of  a  Company  Request   accompanied  by  an  Officer's
Certificate and Opinion of Counsel  certifying that all such obligations of such
Subsidiary Guarantee have terminated.

     Any Subsidiary  Guarantor not released in accordance with this Section 13.3
will remain liable for the full amount of principal of (and premium, if any, on)
and interest on the Notes as provided in this Article 13.

     13.4 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 will 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 13.5 hereof,
result in the  obligations  of such  Subsidiary  Guarantor  under its Subsidiary
Guarantee not constituting such a fraudulent  conveyance or fraudulent transfer.
This  Section  13.4 is for  the  benefit  of the  creditors  of each  Subsidiary
Guarantor.

                                      120


     13.5 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 will
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  Notes or any  other  Subsidiary  Guarantor's  obligations  with
respect to its Subsidiary Guarantee.

     13.6 EXECUTION AND DELIVERY OF NOTATIONS OF SUBSIDIARY GUARANTEES.

     To evidence its Subsidiary Guarantee set forth in Section 13.1 hereof, each
Subsidiary  Guarantor  hereby  agrees to execute  the  notations  of  Subsidiary
Guarantees  in  substantially  the form  set  forth in  Exhibit  A hereto  to be
endorsed on all Notes ordered to be  authenticated  and delivered by the Trustee
and each  Subsidiary  Guarantor  agrees that this  Indenture will be executed on
behalf  of  such  Subsidiary  Guarantor  by its  President  or  one of its  Vice
Presidents.   Each  Subsidiary  Guarantor  hereby  agrees  that  its  Subsidiary
Guarantee  set forth in Section 13.1 hereof will remain in full force and effect
notwithstanding  any  failure  to  endorse  on  each  Note a  notation  of  such
Subsidiary Guarantee.  Each such notation of Subsidiary Guarantee will be signed
on behalf  of each  Subsidiary  Guarantor  by its  President  or one of its Vice
Presidents  (each of whom will, in each case,  have been duly  authorized by all
requisite  corporate action) prior to the authentication of the Note on which it
is  endorsed,  and  the  delivery  of  such  Note  by  the  Trustee,  after  the
authentication thereof hereunder, will constitute due delivery of the Subsidiary
Guarantee set forth in this  Indenture on behalf of such  Subsidiary  Guarantor.
Such  signatures  upon the notation of Subsidiary  Guarantee may be by manual or
facsimile  signature  of  such  officers  and  may  be  imprinted  or  otherwise
reproduced on the  Subsidiary  Guarantee,  and in case any such officer who will
have signed the notation of Subsidiary  Guarantee  will cease to be such officer
before the Note on which such notation of Subsidiary  Guarantee is endorsed will
have been  authenticated  and  delivered  by the  Trustee or  disposed of by the
Company,  such Note  nevertheless may be authenticated and delivered or disposed
of as though the Person who signed the notation of Subsidiary  Guarantee had not
ceased to be such officer of the Subsidiary Guarantor.

     13.7 SEVERABILITY.

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

     13.8 ARTICLE 13 NOT TO PREVENT EVENTS OF DEFAULT.

                                      121


     The failure to make a payment on account of the  Subsidiary  Guarantees  by
reason of any  provision in this Article 13 will not be construed as  preventing
the occurrence of an Event of Default under this Indenture.

     13.9 PAYMENT.

     For purposes of this  Article 13, a payment with respect to any  Subsidiary
Guarantor  or with  respect  to  principal  of or  interest  on the  Note or any
Subsidiary Guarantee will include,  without limitation,  payment of principal of
and interest on any Note, any payment on account of any repurchase or redemption
of any Note and any payment or recovery on any claim  (whether for rescission or
damages and whether based on contract,  tort,  duty imposed by law, or any other
theory of liability)  relating to or arising out of the offer,  sale or purchase
of any Note.

                                   ARTICLE 14
                                  MISCELLANEOUS

     14.1 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, will furnish to the
Trustee  such  certificates  and  opinions  as may be  required  under the Trust
Indenture Act or this  Indenture.  Each such  certificate  and each such opinion
will be in the form of an  Officers'  Certificate  or an Opinion of Counsel,  as
applicable, and will 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 will include:

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

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

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

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

     The  certificates and opinions  provided  pursuant to this Section 14.1 and
the  statements  required by this Section 14.1 will comply in all respects  with
TIA Sections 314(c) and (e).

     14.2 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


                                      122


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
Opinion of Counsel may be based, insofar as it relates to factual matters,  upon
an Officer's  Certificate,  unless such counsel knows 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.

     14.3 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 will 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
appointing  any such agent will 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 will 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 Notes held by any
Person, and the date of holding the same, will be proved by the Note Register.

     (d) If the Company  will  solicit  from the  Holders of Notes 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


                                      123


Company will have no obligation to do so. Notwithstanding  Section 316(c) of the
TIA,  such record date will be the record date  specified in or pursuant to such
Board  Resolution,  which will 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 will be deemed to be
Holders  for the  purposes  of  determining  whether  Holders  of the  requisite
proportion of Outstanding  Notes have  authorized or agreed or consented to such
request, demand, authorization, direction, notice, consent, waiver or other Act,
and for that  purpose the  Outstanding  Notes will be computed as of such record
date, provided that no such  authorization,  agreement or consent by the Holders
on such record  date will be deemed  effective  unless it will 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 Note will bind every future Holder of the same
Note and the Holder of every  Note  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 Note.

     14.4 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

     (a) the Trustee by any Holder or by the Company or any Subsidiary Guarantor
will 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

     (b) the Company or any Subsidiary Guarantor by the Trustee or by any Holder
will  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  principal  office located at 500 North Loop 1604 East, Suite 100, San
Antonio,  Texas 78232, or at any other address otherwise furnished in writing to
the Trustee by the Company.

     14.5 NOTICE TO HOLDERS; WAIVER.

     Where  this  Indenture  provides  for notice of any event to Holders by the
Company, the Trustee or any Paying Agent, such notice will 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 Note  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,


                                      124


neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder will affect the sufficiency of such notice with respect
to other Holders.  Any notice mailed to a Holder in the manner herein prescribed
will 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  herein or after the event,  and such
waiver will be the equivalent of such notice.  Waivers of notice by Holders will
be filed with the Trustee,  but such filing will 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 will 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 will be
satisfactory  to the Trustee  will be deemed to be a  sufficient  giving of such
notice for every purpose hereunder.

     14.6 EFFECT OF HEADINGS AND TABLE OF CONTENTS.

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

     14.7 SUCCESSORS AND ASSIGNS.

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

     14.8 SEPARABILITY CLAUSE.

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

     14.9 BENEFITS OF INDENTURE.

     Nothing in this Indenture or in the Notes, express or implied, will give to
any Person (other than the parties hereto, any Paying Agent, any Notes Registrar
and their  successors  hereunder,  the  Holders  and, to the extent set forth in
Section 13.4  hereof,  creditors of  Subsidiary  Guarantors)  any benefit or any
legal or equitable right, remedy or claim under this Indenture.

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  will,  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 TIA,  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 will control.

     14.11 LEGAL HOLIDAYS.

     In any case where any Interest  Payment  Date,  Redemption  Date, or Stated
Maturity  or  Maturity   of  any  Note  will  not  be  a  Business   Day,   then
(notwithstanding  any other  provision of this  Indenture or of the Notes 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  will accrue for the period  from and after such  Interest  Payment
Date, Redemption Date, Stated Maturity or Maturity, as the case may be.

     14.12 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 will
not have any personal  liability  under the Notes 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  Notes 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 Notes, waives and releases all such liability to the extent
permitted by applicable law.

     14.13 DUPLICATE ORIGINALS.

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

     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.

     Abraxas  Petroleum  Corporation,  a Nevada  corporation  (herein called the
"Company"  which  term  includes  any  successor   Person  under  the  Indenture
hereinafter  referred to), for value received,  hereby promises to pay to CEDE &
CO. or  registered  assignee the  principal sum of ? Dollars ($?) on December 1,
2009 at the  office or  agency  of the  Company  referred  to below,  and to pay
interest  thereon,  commencing  on  June 1,  2005  and  continuing  semiannually
thereafter,  on June 1 and  December 1 in each year (each,  an Interest  Payment
Date),  from October 28, 2004 or from the most recent  Interest  Payment Date to
which  interest has been paid or duly provided for, at a per annum floating rate
of Six-Month LIBOR (as defined below) plus 7.5%,  until the principal  hereof is
paid or duly provided for, and (to the extent lawful) to pay on demand  interest
on any  overdue  interest  at the rate borne by the Notes from the date on which
such  overdue  interest  becomes  payable  to the date on which  payment of such
interest has been made or duly provided for. The Company also hereby promises to
pay the  Liquidated  Damages,  if any,  payable  pursuant  to  Section  3 of the
Registration  Rights Agreement on the same dates on which interest is payable as
provided herein. The interest and Liquidated  Damages,  if any, so payable,  and
punctually  paid or duly  provided  for, on any Interest  Payment Date will,  as
provided  in said  Indenture,  be paid to the Person in whose name this Note (or
one or more  Predecessor  Notes) is registered on the Note Register at the close
of  business  on the Regular  Record  Date for such  interest,  whether or not a
Business Day (as defined below),  next preceding such Interest Payment Date. Any
such interest or Liquidated  Damages not so punctually paid or duly provided for
will  forthwith  cease to be payable to the Holder on such Regular  Record Date,
and such  Defaulted  Interest,  Liquidated  Damages  and (to the extent  lawful)
interest on such Defaulted  Interest and Liquidated Damages at the rate borne by
the  Notes,  may be paid to the  Person in whose  name this Note (or one or more
Predecessor  Notes) is  registered on the Note Register at the close of business
on a Special Record Date for the payment of such Defaulted  Interest to be fixed
by the Trustee,  notice  whereof will be given to Holders of Notes not less than
10 days prior to such  Special  Record  Date,  or may be paid at any time in any
other lawful manner not  inconsistent  with the  requirements  of any securities
exchange  on which  the  Notes may be  listed,  and upon  such  notice as may be
required by such exchange, all as more fully provided in said Indenture.

     Payment of the  principal  of (and  premium,  if any,  on) and interest and
Liquidated Damages, if any, on this Note will be made at the office or agency of
the Company maintained for that purpose in The City of New York, in such coin or
currency  of the  United  States of  America  as at the time of payment is legal
tender for payment of public and private debts; provided,  however, that payment
of interest  and  Liquidated  Damages,  if any, may be made at the option of the
Company by check  mailed to the address of the Person  entitled  thereto as such
address will appear on the Note Register.

                                   Exhibit A-1

     Interest on the Note will accrue from and including the most recent date on
which  interest  has been  paid or,  if no  interest  has  been  paid,  from and
including  the date of  issuance,  until but  excluding  the date upon which the
principal thereof is paid or duly provided for in accordance with the Indenture.
The  interest  rate will be reset  semi-annually  on each June 1 and December 1,
commencing on June 1, 2005 (each such date, an "Interest Reset Date").  Interest
on the Note will be payable  semiannually in arrears on June 1 and December 1 of
each year, commencing on June 1, 2005; provided,  that, if any such day is not a
Business Day, such interest  payment date will be the next  succeeding  Business
Day.

     "Business  Day" means any day other than a Saturday or Sunday,  or a day on
which banking institutions in The City of New York are authorized or required by
law,  regulation  or executive  order to remain closed and that is also a London
Business Day (as defined below).

     "Six-Month  LIBOR"  means  the  rate  determined  in  accordance  with  the
following provisions:

     (1) On the second London  Business Day preceding  each Interest  Reset Date
(each such  date,  an  "Interest  Determination  Date"),  a  calculation  agent,
initially  U.S. Bank National  Association  or a duly  appointed  successor (the
"Calculation  Agent"),  as agent for the Company,  will  determine the Six-Month
LIBOR rate,  which shall be the rate for deposits in the London interbank market
in U.S.  dollars  having  a  six-month  maturity  commencing  on the  succeeding
Interest Reset Date immediately following such Interest Determination Date which
appears on the  Designated  LIBOR Page as of 11:00 a.m.,  London  time,  on such
Interest Determination Date.

     "Designated LIBOR Page" means the display on the Moneyline service (or such
other  service  or  services  as  may  be  nominated  by  the  British  Bankers'
Association) for the purpose of displaying London interbank rates of major banks
for U.S. dollar deposits.  If no such rate appears on an Interest  Determination
Date,  the  Six-Month  LIBOR rate on such  Interest  Determination  Date will be
determined as described in clause (2) of the definition of "Six-Month LIBOR."

     "London  Business  Day"  means any day on which  dealings  in U.S.  dollars
generally are transacted in the London interbank market.

     (2) With respect to an Interest  Determination  Date for which no such rate
appears, the Calculation Agent will request the principal London offices of each
of four major reference banks in the London interbank market, as selected by the
Calculation  Agent  (after  consultation  with  the  Company),  to  provide  the
Calculation Agent with its offered quotation for deposits in U.S. dollars having
a six-month maturity commencing on the Interest Reset Date immediately following
such Interest  Determination  Date to prime banks in the London interbank market
at approximately  11:00 a.m., London time, on such Interest  Determination  Date
and in a principal amount not less than $1,000,000 that is representative  for a
single  transaction in U.S. dollars in such market at such time. If at least two
such  quotations  are  provided,  the  Six-Month  LIBOR  rate on  such  Interest
Determination Date will be the arithmetic mean of such quotations. If fewer than
two  quotations  are  provided,  the  Six-Month  LIBOR rate  determined  on such
Interest  Determination  Date will be the arithmetic mean of the rates quoted at
approximately  11:00 a.m.,  New York City time, on such  Interest  Determination
Date by three  major banks in The City of New York  selected by the  Calculation

                                   Exhibit A-1
                                       2


Agent (after consultation with the Company) for loans in U.S. dollars to leading
European banks,  having a six-month  maturity and in a principal amount not less
than $1,000,000 that is representative  for a single transaction in U.S. dollars
in  such  market  at  such  time.  However,  if the  banks  so  selected  by the
Calculation  Agent are not quoting as mentioned  above, the Six-Month LIBOR rate
with respect to such Interest  Determination  Date will be the  Six-Month  LIBOR
rate in effect immediately prior to such Interest Determination Date.

     All percentages resulting from any calculation on the Note will be rounded,
if necessary,  to the nearest one  hundred-thousandth of a percentage point with
five  one-millionths  of a percentage  point rounded upward and all U.S.  dollar
amounts used in or resulting  from such  calculation on the Note will be rounded
to the nearest cent (with one-half cent being rounded upward).

     Reference is hereby made to the further  provisions  of this Note set forth
on the reverse hereof,  which further  provisions will for all purposes have the
same effect as if set forth at this place.

     Unless the certificate of  authentication  hereon has been duly executed by
the Trustee  referred to on the reverse  hereof by manual  signature,  this Note
will  not be  entitled  to any  benefit  under  the  Indenture,  or be  valid or
obligatory for any purpose.

                            [signature page follows]


                                   Exhibit A-1
                                       3

     IN WITNESS  WHEREOF,  the  Company has caused  this  instrument  to be duly
executed in its corporate  name by the signature of its officer  thereunto  duly
authorized.

                                 Reverse of Note

     This Note is one of a duly  authorized  issue of  securities of the Company
designated as its Floating Rate Senior Secured Notes due 2009 (herein called the
"Notes"),  limited  (except as otherwise  provided in the Indenture  referred to
below) in aggregate principal amount to $125,000,000,  which may be issued under
an indenture (herein called the "Indenture")  dated as of October 28, 2004 among
the Company,  the initial  Subsidiary  Guarantors  named  therein and U.S.  Bank
National  Association  (herein  called the  "Trustee,"  which term  includes any
successor  trustee under the  Indenture),  to which Indenture and all indentures
supplemental  thereto reference is hereby made for a statement of the respective
rights,  limitation of rights, duties,  obligations and immunities thereunder of
the  Company,  the  Subsidiary  Guarantors,  the  Trustee and the Holders of the
Notes,  and of the terms upon which the Notes are, and are to be,  authenticated
and delivered.

Optional Redemption

     The Notes may be  redeemed,  in whole or from time to time in part,  at the
option of the Company at any time after April 28, 2007 upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal  amount) set forth below together with accrued and unpaid interest and
Liquidated Damages, if any, to the applicable redemption date during the periods
indicated below:

                Year                                               Percentage
                ----                                               ----------
                From April 29, 2007 to April 28, 2008........    104.00%
                From April 29, 2008 to April 28, 2009........    102.00%
                After April 28, 2009.........................    100.00%

     Notwithstanding  the  foregoing,  at any time prior to April 29, 2007,  the
Company may, at its option and subject to the  restrictions and other provisions
relating thereto, if any, contained in the Revolving Credit Facility, on any one
or more occasions redeem up to 35% of the original aggregate principal amount of
the  Notes  (i.e.,  $43,750,000)  with  the  Net  Cash  Proceeds  of one or more
Qualified Equity Offerings at a redemption price equal to the product of (x) the
principal  amount of the Notes  being so  redeemed  and (y) a  redemption  price
factor of 1.00 plus the per annum  interest  rate on the Notes  (expressed  as a
decimal) on the applicable  redemption date, plus accrued and unpaid interest to
the applicable redemption date, provided,  that (1) at least 65% of the original
aggregate principal amount of the Notes (i.e.,  $81,250,000) remains outstanding
after each such  redemption;  and (2) any such redemption  occurs within 90 days
after the  closing  of the  Qualified  Equity  Offering  to which  such Net Cash
Proceeds relate.

     If less than all the Notes are to be redeemed at any time,  the  particular
Notes to be redeemed  will be  selected  not fewer than 30 days nor more than 60
days prior to the Redemption Date by the Trustee from the Outstanding  Notes not
previously  called  for  redemption  pro rata or by any  other  method  that the
Trustee  deems fair and  appropriate,  provided  that no Notes of $1,000 or less
will be redeemed in part.  Notices of  redemption  will be mailed by first class
mail at least 30 but not more than 60 days  before the  Redemption  Date to each
Holder of Notes to be redeemed at its registered  address.  If any Note is to be
redeemed in part only,  the notice of redemption  that relates to such Note will


                                   Exhibit A-1
                                       5


state the portion of the principal amount thereof to be redeemed.  A new Note in
principal  amount equal to the unredeemed  portion thereof will be issued in the
name of the holder thereof upon surrender of the original Note. On and after the
Redemption  Date,  interest  will cease to accrue on Notes or  portions  thereof
called for redemption as long as the Company has deposited with the Paying Agent
funds in satisfaction of the applicable  Redemption Price, together with accrued
and unpaid interest and Liquidated Damages, if any, to the Redemption Date.

     If a Redemption  Date is on or after a Regular Record Date and on or before
the  related  Interest  Payment  Date,  the  accrued  and  unpaid  interest  and
Liquidated  Damages,  if any,  on each Note being  redeemed  will be paid to the
person in whose name such Note is  registered  at the close of  business on such
Regular Record Date, and no other interest or Liquidated Damages will be payable
to any other Person who may become a Holder of such Note after such time.

     The Notes do not have the benefit of any sinking fund obligations.

     In the event of a Change of Control of the Company,  and subject to certain
conditions  and  limitations  provided in the  Indenture,  the  Company  will be
obligated to make an offer to purchase  within 30 calendar  days  following  the
occurrence  of a Change of Control of the Company,  all of the then  Outstanding
Notes at a  purchase  price  equal  to 101% of the  aggregate  principal  amount
thereof,  together with accrued and unpaid interest and Liquidated  Damages,  if
any, to the Change of Control Payment Date, all as provided in the Indenture.

     In the event of Asset Sales, under certain circumstances,  the Company will
be obligated to make a Net Proceeds Offer to purchase all or a specified portion
of each  Holder's  Notes at a  purchase  price  equal  to 100% of the  aggregate
principal  amount of the Notes,  together  with accrued and unpaid  interest and
Liquidated  Damages,  if any, to the date such Net Proceeds Offer is consummated
in accordance with the procedures set forth in the Indenture.

     As more  particularly  set forth in the  Indenture,  an Event of Default is
generally  (1) default in the payment when due of the principal of or premium on
any Note, whether such payment is due at Stated Maturity, upon redemption,  upon
repurchase  pursuant to a Change of Control Offer or a Net Proceeds Offer,  upon
declaration of acceleration or otherwise; (2) default in the payment when due of
any installment of interest on, or Liquidated Damages with respect to, any Note,
and the  continuance of such Default for a period of 30 days; (3) default in the
performance or breach of the provisions relating to mergers,  consolidations and
sales of all or substantially  all assets or the failure to make or consummate a
Change of Control Offer or a Net Proceeds  Offer;  (4) failure by the Company or
any Restricted  Subsidiary to comply with any other term,  covenant or agreement
contained in the Notes, any Subsidiary Guarantee, any Collateral Document or the
Indenture (other than a default specified in clause (1), (2) or (3) above) for a
period of 60 days after delivery to the Company or such  Restricted  Subsidiary,
as the case may be, of  written  notice  of such  failure  stating  that it is a
"notice of default" under this  Indenture;  (5) the occurrence and  continuation
beyond any applicable grace period of any default in the payment when due of the
principal of, or premium or interest on, any  Indebtedness for borrowed money of
the Company  (other than the Notes) or any  Restricted  Subsidiary  or any other
default  resulting in acceleration of any Indebtedness for borrowed money of the
Company or any Restricted  Subsidiary,  but only in the event that the aggregate

                                   Exhibit A-1
                                       6



principal  amount of such  Indebtedness  shall  exceed  $2,000,000;  (6) without
limiting  clause (5) above,  the  occurrence  and  continuation  of an "event of
default" under either the Revolving  Credit Facility or the Bridge Loan; (7) any
Subsidiary  Guarantee  shall for any reason  cease to be, or be  asserted by the
Company,  any Subsidiary  Guarantor,  any of their respective  Affiliates or any
Person  acting on behalf of any of the  foregoing  not to be, in full  force and
effect and  enforceable  in any material  respect in  accordance  with its terms
(except pursuant to the release or termination of any such Subsidiary  Guarantee
in accordance with this  Indenture);  (8) any Collateral  Document shall for any
reason cease to be, or be asserted by the Company,  any  Restricted  Subsidiary,
any of their respective  Affiliates or any Person acting on behalf of any of the
foregoing  not to be, in full force and effect and  enforceable  in any material
respect in accordance  with its terms or to not otherwise grant a duly perfected
first  priority  security  interest in the Collateral in favor of the holders of
the Note Obligations  (subject to Permitted Prior Liens and except pursuant to a
release or termination thereof consummated in accordance with this Indenture and
the Intercreditor  Agreement and other Collateral  Documents) for a period of 30
days after delivery of written  notice  thereof  stating that it is a "notice of
default"  under this  Indenture  and  requiring  the  Company or the  respective
Restricted  Subsidiary,  as the case may be,  to  remedy  the  same;  (9)  final
judgments or orders  rendered  against the Company or any Restricted  Subsidiary
that are unsatisfied and that require the payment in money,  either individually
or in an aggregate amount,  that is more than $2,000,000 over the coverage under
applicable  insurance policies and either (a) commencement by any creditor of an
enforcement  proceeding upon such judgment (other than a judgment that is stayed
by reason of pending  appeal or  otherwise)  or (b) the  occurrence  of a 60-day
period  during  which a stay of such  judgment  or order,  by reason of  pending
appeal or otherwise,  was not in effect;  and (10) certain evens of  bankruptcy,
insolvency or reorganization  of the Company or any Subsidiary,  as the case may
be. If any Event of Default has occurred and is  continuing,  the Trustee or the
Holders of not less than 25% in aggregate  principal  amount of the  Outstanding
Notes may declare the principal of, premium, if any, accrued and unpaid interest
and Liquidated Damages, if any, on the Notes to be due and payable  immediately,
except that (i) in the case of an Event of Default arising from certain evens of
bankruptcy,  insolvency or reorganization of the Company or any Subsidiary,  the
principal  of,  premium,  if any,  accrued and unpaid  interest  and  Liquidated
Damages,  if any, on the Notes will become due and payable  immediately  without
further action or notice.

     The Indenture  contains  provisions  for (i)  defeasance at any time of the
entire  indebtedness of the Company on this Note and (ii) discharge from certain
restrictive  covenants  and the related  Defaults  and Events of  Default,  upon
compliance  by the Company  and  certain  conditions  set forth  therein,  which
provisions apply to this Note.

     Subject to the terms of the Intercreditor Agreement, the Indenture permits,
with certain  exceptions as therein  provided,  the amendment  therefore and the
modification  of the rights and  obligations  of the Company and the  Subsidiary
Guarantors  and the rights of the Holders under the Indenture at any time by the
Company,  the  Subsidiary  Guarantors  and the  Trustee  and the  consent of the
Holders of a majority  in  aggregate  principal  amount of the Notes at the time
Outstanding.  The Indenture also contains  provisions  permitting the Holders of
specified  percentages  in aggregate  principal  amount of the Notes at the time
Outstanding,  on behalf of the Holders of all the Notes, to waive  compliance by
the Company with certain  provisions  of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by or on
behalf  of the  Holder of this Note will be  conclusive  and  binding  upon such

                                   Exhibit A-1
                                       7



Holder and upon all future  Holders of this Note and of any Note issued upon the
registration  of  transfer  hereof or in  exchange  hereof for or in lieu hereof

Without the consent of any Holder,  the Company,  the Subsidiary  Guarantors and
the  Trustee  may amend or  supplement  the  Indenture  or the Notes to cure any
ambiguity,  defect or inconsistency,  to add or release any Subsidiary Guarantor
pursuant to the Indenture, to provide for uncertificated Notes in addition to or
in place of certificated  Notes and to make certain other specified  changes and
other  changes that do not  adversely  affect the interests of any Holder in any
material respect.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  will alter or impair the  obligation  of the  Company,  which is

set forth, the transfer of this Note is registerable on the Note Register of the

accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Company  and the Note  Registrar  duly  executed  by, the  Holder  hereof or his
attorney  duly  authorized in writing,  and thereupon one or more new Notes,  of
authorized  denominations and for the same aggregate  principal amount,  will be
issued to the designated transferee or transferees.

Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable  for a like  aggregate  principal  amount  of Notes of a  different
authorized denomination, as requested by the Holder surrendering the same.

     No service charge will be made for any registration of transfer or exchange
of Notes,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

Subsidiary Guarantor under the Notes or the Indenture or for any claim based on,
in respect of, or by reason of such obligations or their creation.  Each Holder,
by  accepting  this Note with the  notation  of  Subsidiary  Guarantee  endorsed
hereon, waives and releases all such liability. Such waiver and release are part
of the  consideration  for the  issuance  of this  Note  with  the  notation  of
Subsidiary Guarantee endorsed hereon.

     Prior  to the  time of due  presentment  of this  Note of  registration  of
transfer, the Company, the Subsidiary  Guarantors,  the Trustee and any agent of
the  Company  or the  Trustee  may treat the  Person in whose  name this Note is

obligations of any Subsidiary  Guarantor under the Notes or the Indenture or for
any claim  based on, in respect  of, or by reason of such  obligations  or their
creation.

     Any Subsidiary Guarantor may be released from its Subsidiary Guarantee upon

of any transfer or assignment of rights by any Holder or the Trustee  respecting
the Note upon which the foregoing  Subsidiary  Guarantees are noted,  the rights
and privileges herein conferred upon that party will automatically extend to and

hereinafter  referred to), for value received,  hereby promises to pay to CEDE &

2009 at the  office or  agency  of the  Company  referred  to below,  and to pay
interest  thereon,  commencing  on  June 1,  2005  and  continuing  semiannually

of Six-Month LIBOR (as defined below) plus 7.5%,  until the principal  hereof is
paid or duly provided for, and (to the extent lawful) to pay on demand  interest
on any  overdue  interest  at the rate borne by the Notes from the date on which
such  overdue  interest  becomes  payable  to the date on which  payment of such
interest has been made or duly provided for. The Company also hereby promises to
pay the  Liquidated  Damages,  if any,  payable  pursuant  to  Section  3 of the
Registration  Rights Agreement on the same dates on which interest is payable as
provided herein. The interest and Liquidated  Damages,  if any, so payable,  and
punctually  paid or duly  provided  for, on any Interest  Payment Date will,  as
provided  in said  Indenture,  be paid to the Person in whose name this Note (or
one or more  Predecessor  Notes) is registered on the Note Register at the close

Business Day (as defined below),  next preceding such Interest Payment Date. Any
such interest or Liquidated  Damages not so punctually paid or duly provided for

and such  Defaulted  Interest,  Liquidated  Damages  and (to the extent  lawful)
interest on such Defaulted  Interest and Liquidated Damages at the rate borne by
the  Notes,  may be paid to the  Person in whose  name this Note (or one or more

by the Trustee,  notice  whereof will be given to Holders of Notes not less than
10 days prior to such  Special  Record  Date,  or may be paid at any time in any
other lawful manner not  inconsistent  with the  requirements  of any securities
exchange  on which  the  Notes may be  listed,  and upon  such  notice as may be
required by such exchange, all as more fully provided in said Indenture.

     Payment of the  principal  of (and  premium,  if any,  on) and interest and
Liquidated Damages, if any, on this Note will be made at the office or agency of
the Company maintained for that purpose in The City of New York, in such coin or
currency  of the  United  States of  America  as at the time of payment is legal
tender for payment of public and private debts; provided,  however, that payment
of interest  and  Liquidated  Damages,  if any, may be made at the option of the
Company by check  mailed to the address of the Person  entitled  thereto as such
address will appear on the Note Register.

                                  Exhibit A-2


     Interest on the Note will accrue from and including the most recent date on
which  interest  has been  paid or,  if no  interest  has  been  paid,  from and
including  the date of  issuance,  until but  excluding  the date upon which the
principal thereof is paid or duly provided for in accordance with the Indenture.
The  interest  rate will be reset  semi-annually  on each June 1 and December 1,
commencing on June 1, 2005 (each such date, an "Interest Reset Date").  Interest
on the Note will be payable  semiannually in arrears on June 1 and December 1 of
each year, commencing on June 1, 2005; provided,  that, if any such day is not a
Business Day, such interest  payment date will be the next  succeeding  Business
Day.

     "Business  Day" means any day other than a Saturday or Sunday,  or a day on
which banking institutions in The City of New York are authorized or required by
law,  regulation  or executive  order to remain closed and that is also a London
Business Day (as defined below).

     "Six-Month  LIBOR"  means  the  rate  determined  in  accordance  with  the
following provisions:

     (1) On the second London  Business Day preceding  each Interest  Reset Date
(each such  date,  an  "Interest  Determination  Date"),  a  calculation  agent,
initially  U.S. Bank National  Association  or a duly  appointed  successor (the
"Calculation  Agent"),  as agent for the Company,  will  determine the Six-Month
LIBOR rate,  which shall be the rate for deposits in the London interbank market
in U.S.  dollars  having  a  six-month  maturity  commencing  on the  succeeding
Interest Reset Date immediately following such Interest Determination Date which
appears on the  Designated  LIBOR Page as of 11:00 a.m.,  London  time,  on such
Interest Determination Date.

     "Designated LIBOR Page" means the display on the Moneyline service (or such
other  service  or  services  as  may  be  nominated  by  the  British  Bankers'
Association) for the purpose of displaying London interbank rates of major banks
for U.S. dollar deposits.  If no such rate appears on an Interest  Determination
Date,  the  Six-Month  LIBOR rate on such  Interest  Determination  Date will be
determined as described in clause (2) of the definition of "Six-Month LIBOR."

     "London  Business  Day"  means any day on which  dealings  in U.S.  dollars
generally are transacted in the London interbank market.

     (2) With respect to an Interest  Determination  Date for which no such rate
appears, the Calculation Agent will request the principal London offices of each
of four major reference banks in the London interbank market, as selected by the
Calculation  Agent  (after  consultation  with  the  Company),  to  provide  the
Calculation Agent with its offered quotation for deposits in U.S. dollars having
a six-month maturity commencing on the Interest Reset Date immediately following
such Interest  Determination  Date to prime banks in the London interbank market
at approximately  11:00 a.m., London time, on such Interest  Determination  Date
and in a principal amount not less than $1,000,000 that is representative  for a
single  transaction in U.S. dollars in such market at such time. If at least two
such  quotations  are  provided,  the  Six-Month  LIBOR  rate on  such  Interest
Determination Date will be the arithmetic mean of such quotations. If fewer than
two  quotations  are  provided,  the  Six-Month  LIBOR rate  determined  on such
Interest  Determination  Date will be the arithmetic mean of the rates quoted at


                                  Exhibit A-2
                                       2


approximately  11:00 a.m.,  New York City time, on such  Interest  Determination
Date by three  major banks in The City of New York  selected by the  Calculation
Agent (after consultation with the Company) for loans in U.S. dollars to leading
European banks,  having a six-month  maturity and in a principal amount not less
than $1,000,000 that is representative  for a single transaction in U.S. dollars
in  such  market  at  such  time.  However,  if the  banks  so  selected  by the
Calculation  Agent are not quoting as mentioned  above, the Six-Month LIBOR rate
with respect to such Interest  Determination  Date will be the  Six-Month  LIBOR
rate in effect immediately prior to such Interest Determination Date.

     All percentages resulting from any calculation on the Note will be rounded,
if necessary,  to the nearest one  hundred-thousandth of a percentage point with
five  one-millionths  of a percentage  point rounded upward and all U.S.  dollar
amounts used in or resulting  from such  calculation on the Note will be rounded
to the nearest cent (with one-half cent being rounded upward).

                                 Reverse of Note

     This Note is one of a duly  authorized  issue of  securities of the Company
designated as its Floating Rate Senior Secured Notes due 2009 (herein called the
"Notes"),  limited  (except as otherwise  provided in the Indenture  referred to
below) in aggregate principal amount to $125,000,000,  which may be issued under
an indenture (herein called the "Indenture")  dated as of October 28, 2004 among
the Company,  the initial  Subsidiary  Guarantors  named  therein and U.S.  Bank
National  Association  (herein  called the  "Trustee,"  which term  includes any
successor  trustee under the  Indenture),  to which Indenture and all indentures
supplemental  thereto reference is hereby made for a statement of the respective
rights,  limitation of rights, duties,  obligations and immunities thereunder of
the  Company,  the  Subsidiary  Guarantors,  the  Trustee and the Holders of the
Notes,  and of the terms upon which the Notes are, and are to be,  authenticated
and delivered.

Optional Redemption

     The Notes may be  redeemed,  in whole or from time to time in part,  at the
option of the Company at any time after April 28, 2007 upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal  amount) set forth below together with accrued and unpaid interest and
Liquidated Damages, if any, to the applicable redemption date during the periods
indicated below:

                Year                                          Percentage
                ----                                          ----------
                From April 29, 2007 to April 28, 2008....   104.00%
                From April 29, 2008 to April 28, 2009....   102.00%
                After April 28, 2009.....................   100.00%

     Notwithstanding  the  foregoing,  at any time prior to April 29, 2007,  the
Company may, at its option and subject to the  restrictions and other provisions
relating thereto, if any, contained in the Revolving Credit Facility, on any one
or more occasions redeem up to 35% of the original aggregate principal amount of
the  Notes  (i.e.,  $43,750,000)  with  the  Net  Cash  Proceeds  of one or more
Qualified Equity Offerings at a redemption price equal to the product of (x) the
principal  amount of the Notes  being so  redeemed  and (y) a  redemption  price
factor of 1.00 plus the per annum  interest  rate on the Notes  (expressed  as a
decimal) on the applicable  redemption date, plus accrued and unpaid interest to
the applicable redemption date, provided,  that (1) at least 65% of the original
aggregate principal amount of the Notes (i.e.,  $81,250,000) remains outstanding
after each such  redemption;  and (2) any such redemption  occurs within 90 days
after the  closing  of the  Qualified  Equity  Offering  to which  such Net Cash
Proceeds relate.

     If less than all the Notes are to be redeemed at any time,  the  particular
Notes to be redeemed  will be  selected  not fewer than 30 days nor more than 60
days prior to the Redemption Date by the Trustee from the Outstanding  Notes not
previously  called  for  redemption  pro rata or by any  other  method  that the
Trustee  deems fair and  appropriate,  provided  that no Notes of $1,000 or less
will be redeemed in part.  Notices of  redemption  will be mailed by first class
mail at least 30 but not more than 60 days  before the  Redemption  Date to each
Holder of Notes to be redeemed at its registered  address.  If any Note is to be
redeemed in part only,  the notice of redemption  that relates to such Note will

                                  Exhibit A-2
                                       5



state the portion of the principal amount thereof to be redeemed.  A new Note in
principal  amount equal to the unredeemed  portion thereof will be issued in the
name of the holder thereof upon surrender of the original Note. On and after the
Redemption  Date,  interest  will cease to accrue on Notes or  portions  thereof
called for redemption as long as the Company has deposited with the Paying Agent
funds in satisfaction of the applicable  Redemption Price, together with accrued
and unpaid interest and Liquidated Damages, if any, to the Redemption Date.

     If a Redemption  Date is on or after a Regular Record Date and on or before
the  related  Interest  Payment  Date,  the  accrued  and  unpaid  interest  and
Liquidated  Damages,  if any,  on each Note being  redeemed  will be paid to the
person in whose name such Note is  registered  at the close of  business on such
Regular Record Date, and no other interest or Liquidated Damages will be payable
to any other Person who may become a Holder of such Note after such time.

     The Notes do not have the benefit of any sinking fund obligations.

     In the event of a Change of Control of the Company,  and subject to certain
conditions  and  limitations  provided in the  Indenture,  the  Company  will be
obligated to make an offer to purchase  within 30 calendar  days  following  the
occurrence  of a Change of Control of the Company,  all of the then  Outstanding
Notes at a  purchase  price  equal  to 101% of the  aggregate  principal  amount
thereof,  together with accrued and unpaid interest and Liquidated  Damages,  if
any, to the Change of Control Payment Date, all as provided in the Indenture.

     In the event of Asset Sales, under certain circumstances,  the Company will
be obligated to make a Net Proceeds Offer to purchase all or a specified portion
of each  Holder's  Notes at a  purchase  price  equal  to 100% of the  aggregate
principal  amount of the Notes,  together  with accrued and unpaid  interest and
Liquidated  Damages,  if any, to the date such Net Proceeds Offer is consummated
in accordance with the procedures set forth in the Indenture.

     As more  particularly  set forth in the  Indenture,  an Event of Default is
generally  (1) default in the payment when due of the principal of or premium on
any Note, whether such payment is due at Stated Maturity, upon redemption,  upon
repurchase  pursuant to a Change of Control Offer or a Net Proceeds Offer,  upon
declaration of acceleration or otherwise; (2) default in the payment when due of
any installment of interest on, or Liquidated Damages with respect to, any Note,
and the  continuance of such Default for a period of 30 days; (3) default in the
performance or breach of the provisions relating to mergers,  consolidations and
sales of all or substantially  all assets or the failure to make or consummate a
Change of Control Offer or a Net Proceeds  Offer;  (4) failure by the Company or
any Restricted  Subsidiary to comply with any other term,  covenant or agreement
contained in the Notes, any Subsidiary Guarantee, any Collateral Document or the
Indenture (other than a default specified in clause (1), (2) or (3) above) for a
period of 60 days after delivery to the Company or such  Restricted  Subsidiary,
as the case may be, of  written  notice  of such  failure  stating  that it is a
"notice of default" under this  Indenture;  (5) the occurrence and  continuation
beyond any applicable grace period of any default in the payment when due of the
principal of, or premium or interest on, any  Indebtedness for borrowed money of
the Company  (other than the Notes) or any  Restricted  Subsidiary  or any other
default  resulting in acceleration of any Indebtedness for borrowed money of the
Company or any Restricted  Subsidiary,  but only in the event that the aggregate

                                  Exhibit A-2
                                       6



principal  amount of such  Indebtedness  shall  exceed  $2,000,000;  (6) without
limiting  clause (5) above,  the  occurrence  and  continuation  of an "event of
default" under either the Revolving  Credit Facility or the Bridge Loan; (7) any
Subsidiary  Guarantee  shall for any reason  cease to be, or be  asserted by the
Company,  any Subsidiary  Guarantor,  any of their respective  Affiliates or any
Person  acting on behalf of any of the  foregoing  not to be, in full  force and
effect and  enforceable  in any material  respect in  accordance  with its terms
(except pursuant to the release or termination of any such Subsidiary  Guarantee
in accordance with this  Indenture);  (8) any Collateral  Document shall for any
reason cease to be, or be asserted by the Company,  any  Restricted  Subsidiary,
any of their respective  Affiliates or any Person acting on behalf of any of the
foregoing  not to be, in full force and effect and  enforceable  in any material
respect in accordance  with its terms or to not otherwise grant a duly perfected
first  priority  security  interest in the Collateral in favor of the holders of
the Note Obligations  (subject to Permitted Prior Liens and except pursuant to a
release or termination thereof consummated in accordance with this Indenture and
the Intercreditor  Agreement and other Collateral  Documents) for a period of 30
days after delivery of written  notice  thereof  stating that it is a "notice of
default"  under this  Indenture  and  requiring  the  Company or the  respective
Restricted  Subsidiary,  as the case may be,  to  remedy  the  same;  (9)  final
judgments or orders  rendered  against the Company or any Restricted  Subsidiary
that are unsatisfied and that require the payment in money,  either individually
or in an aggregate amount,  that is more than $2,000,000 over the coverage under
applicable  insurance policies and either (a) commencement by any creditor of an
enforcement  proceeding upon such judgment (other than a judgment that is stayed
by reason of pending  appeal or  otherwise)  or (b) the  occurrence  of a 60-day
period  during  which a stay of such  judgment  or order,  by reason of  pending
appeal or otherwise,  was not in effect;  and (10) certain evens of  bankruptcy,
insolvency or reorganization  of the Company or any Subsidiary,  as the case may
be. If any Event of Default has occurred and is  continuing,  the Trustee or the
Holders of not less than 25% in aggregate  principal  amount of the  Outstanding
Notes may declare the principal of, premium, if any, accrued and unpaid interest
and Liquidated Damages, if any, on the Notes to be due and payable  immediately,
except that (i) in the case of an Event of Default arising from certain evens of
bankruptcy,  insolvency or reorganization of the Company or any Subsidiary,  the
principal  of,  premium,  if any,  accrued and unpaid  interest  and  Liquidated
Damages,  if any, on the Notes will become due and payable  immediately  without
further action or notice.

     The Indenture  contains  provisions  for (i)  defeasance at any time of the
entire  indebtedness of the Company on this Note and (ii) discharge from certain
restrictive  covenants  and the related  Defaults  and Events of  Default,  upon
compliance  by the Company  and  certain  conditions  set forth  therein,  which
provisions apply to this Note.

     Subject to the terms of the Intercreditor Agreement, the Indenture permits,
with certain  exceptions as therein  provided,  the amendment  therefore and the
modification  of the rights and  obligations  of the Company and the  Subsidiary
Guarantors  and the rights of the Holders under the Indenture at any time by the
Company,  the  Subsidiary  Guarantors  and the  Trustee  and the  consent of the
Holders of a majority  in  aggregate  principal  amount of the Notes at the time
Outstanding.  The Indenture also contains  provisions  permitting the Holders of
specified  percentages  in aggregate  principal  amount of the Notes at the time
Outstanding,  on behalf of the Holders of all the Notes, to waive  compliance by
the Company with certain  provisions  of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by or on
behalf  of the  Holder of this Note will be  conclusive  and  binding  upon such

                                  Exhibit A-2
                                       7



Holder and upon all future  Holders of this Note and of any Note issued upon the
registration  of  transfer  hereof or in  exchange  hereof for or in lieu hereof
whether  or not  notation  of such  consent  or waiver  is made upon this  Note.
Without the consent of any Holder,  the Company,  the Subsidiary  Guarantors and
the  Trustee  may amend or  supplement  the  Indenture  or the Notes to cure any
ambiguity,  defect or inconsistency,  to add or release any Subsidiary Guarantor
pursuant to the Indenture, to provide for uncertificated Notes in addition to or
in place of certificated  Notes and to make certain other specified  changes and
other  changes that do not  adversely  affect the interests of any Holder in any
material respect.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  will alter or impair the  obligation  of the  Company,  which is
absolute and  unconditional,  to pay the principal of (and premium,  if any, on)

and in the coin or currency, herein prescribed.

     As provided in the Indenture,  and subject to certain  limitations  therein
set forth, the transfer of this Note is registerable on the Note Register of the
Company,  upon surrender of this Note for registration of transfer at the office
or agency of the  Company  maintained  for such  purpose  duly  endorsed  by, or
accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Company  and the Note  Registrar  duly  executed  by, the  Holder  hereof or his
attorney  duly  authorized in writing,  and thereupon one or more new Notes,  of
authorized  denominations and for the same aggregate  principal amount,  will be
issued to the designated transferee or transferees.

     The  Notes  are  issuable  only  in  registered  form  without  coupons  in
denominations of $1,000 and any integral  multiple  thereof.  As provided in the
Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable  for a like  aggregate  principal  amount  of Notes of a  different
authorized denomination, as requested by the Holder surrendering the same.

     No service charge will be made for any registration of transfer or exchange
of Notes,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     No director, officer, employee,  incorporator,  stockholder or Affiliate of
the Company or any Subsidiary Guarantor,  as such, past, present or future, will
have any personal  liability  under this Note or the Indenture by reason of his,
her or its status as such director, officer, employee, incorporator, stockholder
or  Affiliate,  or any  liability  for any  obligations  of the  Company  or any
Subsidiary Guarantor under the Notes or the Indenture or for any claim based on,
in respect of, or by reason of such obligations or their creation.  Each Holder,
by  accepting  this Note with the  notation  of  Subsidiary  Guarantee  endorsed
hereon, waives and releases all such liability. Such waiver and release are part
of the  consideration  for the  issuance  of this  Note  with  the  notation  of
Subsidiary Guarantee endorsed hereon.

     Prior  to the  time of due  presentment  of this  Note of  registration  of
transfer, the Company, the Subsidiary  Guarantors,  the Trustee and any agent of
the  Company  or the  Trustee  may treat the  Person in whose  name this Note is
registered  as the owner  hereof for all  purposes,  whether or not this Note is
overdue, and neither the Company, the Subsidiary Guarantors, the Trustee nor any
agent will be affected by notice to the contrary.

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 its contribution  obligations under the
Indenture,  result in the  obligations of such  Subsidiary  Guarantor  under the
Subsidiary  Guarantee  not  constituting  a fraudulent  conveyance or fraudulent

Guarantor will have any personal  liability  under its  Subsidiary  Guarantee by
reason of his, her or its status as such member, partner, stockholder,  officer,
director, manager, employee, incorporator or Affiliate, or any liability for any
obligations of any Subsidiary  Guarantor under the Notes or the Indenture or for
any claim  based on, in respect  of, or by reason of such  obligations  or their
creation.

     Any Subsidiary Guarantor may be released from its Subsidiary Guarantee upon
the terms and subject to the conditions provided in the Indenture.

     All terms used in this notation of Subsidiary  Guarantee  which are defined
in the Indenture referred to in this Note upon which this notation of Subsidiary
Guarantees  is  endorsed  will  have  the  meanings  assigned  to  them  in such
Indenture.

     The Subsidiary  Guarantees  will be binding upon the Subsidiary  Guarantors
and will inure to the benefit of the  Trustee and the Holders  and, in the event
of any transfer or assignment of rights by any Holder or the Trustee  respecting
the Note upon which the foregoing  Subsidiary  Guarantees are noted,  the rights

and privileges herein conferred upon that party will automatically extend to and
be  vested  in such  transferee  or  assignee,  all  subject  to the  terms  and
conditions hereof and in the Indenture.

     Abraxas  Petroleum  Corporation,  a Nevada  corporation  (herein called the
"Company"  which  term  includes  any  successor   Person  under  the  Indenture
hereinafter  referred to), for value received,  hereby promises to pay to CEDE &
CO. or  registered  assignee the  principal sum of ? Dollars ($?) on December 1,
2009 at the  office or  agency  of the  Company  referred  to below,  and to pay
interest  thereon,  commencing  on  June 1,  2005  and  continuing  semiannually
thereafter,  on June 1 and  December 1 in each year (each,  an Interest  Payment
Date),  from October 28, 2004 or from the most recent  Interest  Payment Date to
which  interest has been paid or duly provided for, at a per annum floating rate
of Six-Month LIBOR (as defined below) plus 7.5%,  until the principal  hereof is
paid or duly provided for, and (to the extent lawful) to pay on demand  interest
on any  overdue  interest  at the rate borne by the Notes from the date on which
such  overdue  interest  becomes  payable  to the date on which  payment of such
interest has been made or duly provided for. The Company also hereby promises to
pay the  Liquidated  Damages,  if any,  payable  pursuant  to  Section  3 of the
Registration  Rights Agreement on the same dates on which interest is payable as
provided herein. The interest and Liquidated  Damages,  if any, so payable,  and
punctually  paid or duly  provided  for, on any Interest  Payment Date will,  as
provided  in said  Indenture,  be paid to the Person in whose name this Note (or
one or more  Predecessor  Notes) is registered on the Note Register at the close
of  business  on the Regular  Record  Date for such  interest,  whether or not a
Business Day (as defined below),  next preceding such Interest Payment Date. Any
such interest or Liquidated  Damages not so punctually paid or duly provided for
will  forthwith  cease to be payable to the Holder on such Regular  Record Date,
and such  Defaulted  Interest,  Liquidated  Damages  and (to the extent  lawful)
interest on such Defaulted  Interest and Liquidated Damages at the rate borne by
the  Notes,  may be paid to the  Person in whose  name this Note (or one or more
Predecessor  Notes) is  registered on the Note Register at the close of business
on a Special Record Date for the payment of such Defaulted  Interest to be fixed
by the Trustee,  notice  whereof will be given to Holders of Notes not less than
10 days prior to such  Special  Record  Date,  or may be paid at any time in any
other lawful manner not  inconsistent  with the  requirements  of any securities
exchange  on which  the  Notes may be  listed,  and upon  such  notice as may be
required by such exchange, all as more fully provided in said Indenture.

         Payment of the principal of (and premium, if any, on) and interest and
Liquidated Damages, if any, on this Note will be made at the office or agency of
the Company maintained for that purpose in The City of New York, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that payment
of interest and Liquidated Damages, if any, may be made at the option of the
Company by check mailed to the address of the Person entitled thereto as such
address will appear on the Note Register.

                                  Exhibit A-3



     Interest on the Note will accrue from and including the most recent date on
which  interest  has been  paid or,  if no  interest  has  been  paid,  from and
including  the date of  issuance,  until but  excluding  the date upon which the
principal thereof is paid or duly provided for in accordance with the Indenture.
The  interest  rate will be reset  semi-annually  on each June 1 and December 1,
commencing on June 1, 2005 (each such date, an "Interest Reset Date").  Interest
on the Note will be payable  semiannually in arrears on June 1 and December 1 of
each year, commencing on June 1, 2005; provided,  that, if any such day is not a
Business Day, such interest  payment date will be the next  succeeding  Business
Day.

     "Business  Day" means any day other than a Saturday or Sunday,  or a day on
which banking institutions in The City of New York are authorized or required by
law,  regulation  or executive  order to remain closed and that is also a London
Business Day (as defined below).

     "Six-Month  LIBOR"  means  the  rate  determined  in  accordance  with  the
following provisions:

     (1) On the second London  Business Day preceding  each Interest  Reset Date
(each such  date,  an  "Interest  Determination  Date"),  a  calculation  agent,
initially  U.S. Bank National  Association  or a duly  appointed  successor (the
"Calculation  Agent"),  as agent for the Company,  will  determine the Six-Month
LIBOR rate,  which shall be the rate for deposits in the London interbank market
in U.S.  dollars  having  a  six-month  maturity  commencing  on the  succeeding
Interest Reset Date immediately following such Interest Determination Date which
appears on the  Designated  LIBOR Page as of 11:00 a.m.,  London  time,  on such
Interest Determination Date.

     "Designated LIBOR Page" means the display on the Moneyline service (or such
other  service  or  services  as  may  be  nominated  by  the  British  Bankers'
Association) for the purpose of displaying London interbank rates of major banks
for U.S. dollar deposits.  If no such rate appears on an Interest  Determination
Date,  the  Six-Month  LIBOR rate on such  Interest  Determination  Date will be
determined as described in clause (2) of the definition of "Six-Month LIBOR."

     "London  Business  Day"  means any day on which  dealings  in U.S.  dollars
generally are transacted in the London interbank market.

     (2) With respect to an Interest  Determination  Date for which no such rate
appears, the Calculation Agent will request the principal London offices of each
of four major reference banks in the London interbank market, as selected by the
Calculation  Agent  (after  consultation  with  the  Company),  to  provide  the
Calculation Agent with its offered quotation for deposits in U.S. dollars having
a six-month maturity commencing on the Interest Reset Date immediately following
such Interest  Determination  Date to prime banks in the London interbank market
at approximately  11:00 a.m., London time, on such Interest  Determination  Date
and in a principal amount not less than $1,000,000 that is representative  for a
single  transaction in U.S. dollars in such market at such time. If at least two
such  quotations  are  provided,  the  Six-Month  LIBOR  rate on  such  Interest
Determination Date will be the arithmetic mean of such quotations. If fewer than
two  quotations  are  provided,  the  Six-Month  LIBOR rate  determined  on such
Interest  Determination  Date will be the arithmetic mean of the rates quoted at
approximately  11:00 a.m.,  New York City time, on such  Interest  Determination
Date by three  major banks in The City of New York  selected by the  Calculation

                                  Exhibit A-3


Agent (after consultation with the Company) for loans in U.S. dollars to leading
European banks,  having a six-month  maturity and in a principal amount not less
than $1,000,000 that is representative  for a single transaction in U.S. dollars
in  such  market  at  such  time.  However,  if the  banks  so  selected  by the
Calculation  Agent are not quoting as mentioned  above, the Six-Month LIBOR rate
with respect to such Interest  Determination  Date will be the  Six-Month  LIBOR
rate in effect immediately prior to such Interest Determination Date.

     All percentages resulting from any calculation on the Note will be rounded,
if necessary,  to the nearest one  hundred-thousandth of a percentage point with
five  one-millionths  of a percentage  point rounded upward and all U.S.  dollar
amounts used in or resulting  from such  calculation on the Note will be rounded
to the nearest cent (with one-half cent being rounded upward).

     Reference is hereby made to the further  provisions  of this Note set forth
on the reverse hereof,  which further  provisions will for all purposes have the
same effect as if set forth at this place.

     Unless the certificate of  authentication  hereon has been duly executed by
the Trustee  referred to on the reverse  hereof by manual  signature,  this Note
will  not be  entitled  to any  benefit  under  the  Indenture,  or be  valid or
obligatory for any purpose.

                                  Exhibit A-3
                                       3


         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed in its corporate name by the signature of its officer thereunto duly
authorized.

                                 Reverse of Note

     This Note is one of a duly  authorized  issue of  securities of the Company
designated as its Floating Rate Senior Secured Notes due 2009 (herein called the
"Notes"),  limited  (except as otherwise  provided in the Indenture  referred to
below) in aggregate principal amount to $125,000,000,  which may be issued under
an indenture (herein called the "Indenture")  dated as of October 28, 2004 among
the Company,  the initial  Subsidiary  Guarantors  named  therein and U.S.  Bank
National  Association  (herein  called the  "Trustee,"  which term  includes any
successor  trustee under the  Indenture),  to which Indenture and all indentures
supplemental  thereto reference is hereby made for a statement of the respective
rights,  limitation of rights, duties,  obligations and immunities thereunder of
the  Company,  the  Subsidiary  Guarantors,  the  Trustee and the Holders of the
Notes,  and of the terms upon which the Notes are, and are to be,  authenticated
and delivered.

Optional Redemption

     The Notes may be  redeemed,  in whole or from time to time in part,  at the
option of the Company at any time after April 28, 2007 upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed as percentages of
principal  amount) set forth below together with accrued and unpaid interest and
Liquidated Damages, if any, to the applicable redemption date during the periods
indicated below:

                Year                                             Percentage
                ----                                            ----------
                From April 29, 2007 to April 28, 2008........   104.00%
                From April 29, 2008 to April 28, 2009........   102.00%
                After April 28, 2009.........................   100.00%

     Notwithstanding  the  foregoing,  at any time prior to April 29, 2007,  the
Company may, at its option and subject to the  restrictions and other provisions
relating thereto, if any, contained in the Revolving Credit Facility, on any one
or more occasions redeem up to 35% of the original aggregate principal amount of
the  Notes  (i.e.,  $43,750,000)  with  the  Net  Cash  Proceeds  of one or more
Qualified Equity Offerings at a redemption price equal to the product of (x) the
principal  amount of the Notes  being so  redeemed  and (y) a  redemption  price
factor of 1.00 plus the per annum  interest  rate on the Notes  (expressed  as a
decimal) on the applicable  redemption date, plus accrued and unpaid interest to
the applicable redemption date, provided,  that (1) at least 65% of the original
aggregate principal amount of the Notes (i.e.,  $81,250,000) remains outstanding
after each such  redemption;  and (2) any such redemption  occurs within 90 days
after the  closing  of the  Qualified  Equity  Offering  to which  such Net Cash
Proceeds relate.

     If less than all the Notes are to be redeemed at any time,  the  particular
Notes to be redeemed  will be  selected  not fewer than 30 days nor more than 60
days prior to the Redemption Date by the Trustee from the Outstanding  Notes not
previously  called  for  redemption  pro rata or by any  other  method  that the
Trustee  deems fair and  appropriate,  provided  that no Notes of $1,000 or less
will be redeemed in part.  Notices of  redemption  will be mailed by first class
mail at least 30 but not more than 60 days  before the  Redemption  Date to each
Holder of Notes to be redeemed at its registered  address.  If any Note is to be
redeemed in part only,  the notice of redemption  that relates to such Note will


                                  Exhibit A-3
                                       5



state the portion of the principal amount thereof to be redeemed.  A new Note in
principal  amount equal to the unredeemed  portion thereof will be issued in the
name of the holder thereof upon surrender of the original Note. On and after the
Redemption  Date,  interest  will cease to accrue on Notes or  portions  thereof
called for redemption as long as the Company has deposited with the Paying Agent
funds in satisfaction of the applicable  Redemption Price, together with accrued
and unpaid interest and Liquidated Damages, if any, to the Redemption Date.

     If a Redemption  Date is on or after a Regular Record Date and on or before
the  related  Interest  Payment  Date,  the  accrued  and  unpaid  interest  and
Liquidated  Damages,  if any,  on each Note being  redeemed  will be paid to the
person in whose name such Note is  registered  at the close of  business on such
Regular Record Date, and no other interest or Liquidated Damages will be payable
to any other Person who may become a Holder of such Note after such time.

     The Notes do not have the benefit of any sinking fund obligations.

     In the event of a Change of Control of the Company,  and subject to certain
conditions  and  limitations  provided in the  Indenture,  the  Company  will be
obligated to make an offer to purchase  within 30 calendar  days  following  the
occurrence  of a Change of Control of the Company,  all of the then  Outstanding
Notes at a  purchase  price  equal  to 101% of the  aggregate  principal  amount
thereof,  together with accrued and unpaid interest and Liquidated  Damages,  if
any, to the Change of Control Payment Date, all as provided in the Indenture.

     In the event of Asset Sales, under certain circumstances,  the Company will
be obligated to make a Net Proceeds Offer to purchase all or a specified portion
of each  Holder's  Notes at a  purchase  price  equal  to 100% of the  aggregate
principal  amount of the Notes,  together  with accrued and unpaid  interest and
Liquidated  Damages,  if any, to the date such Net Proceeds Offer is consummated
in accordance with the procedures set forth in the Indenture.

     As more  particularly  set forth in the  Indenture,  an Event of Default is
generally  (1) default in the payment when due of the principal of or premium on
any Note, whether such payment is due at Stated Maturity, upon redemption,  upon
repurchase  pursuant to a Change of Control Offer or a Net Proceeds Offer,  upon
declaration of acceleration or otherwise; (2) default in the payment when due of
any installment of interest on, or Liquidated Damages with respect to, any Note,
and the  continuance of such Default for a period of 30 days; (3) default in the
performance or breach of the provisions relating to mergers,  consolidations and
sales of all or substantially  all assets or the failure to make or consummate a
Change of Control Offer or a Net Proceeds  Offer;  (4) failure by the Company or
any Restricted  Subsidiary to comply with any other term,  covenant or agreement
contained in the Notes, any Subsidiary Guarantee, any Collateral Document or the
Indenture (other than a default specified in clause (1), (2) or (3) above) for a
period of 60 days after delivery to the Company or such  Restricted  Subsidiary,
as the case may be, of  written  notice  of such  failure  stating  that it is a
"notice of default" under this  Indenture;  (5) the occurrence and  continuation
beyond any applicable grace period of any default in the payment when due of the
principal of, or premium or interest on, any  Indebtedness for borrowed money of
the Company  (other than the Notes) or any  Restricted  Subsidiary  or any other
default  resulting in acceleration of any Indebtedness for borrowed money of the

                                  Exhibit A-3
                                       6



Company or any Restricted  Subsidiary,  but only in the event that the aggregate
principal  amount of such  Indebtedness  shall  exceed  $2,000,000;  (6) without
limiting  clause (5) above,  the  occurrence  and  continuation  of an "event of
default" under either the Revolving  Credit Facility or the Bridge Loan; (7) any
Subsidiary  Guarantee  shall for any reason  cease to be, or be  asserted by the
Company,  any Subsidiary  Guarantor,  any of their respective  Affiliates or any
Person  acting on behalf of any of the  foregoing  not to be, in full  force and
effect and  enforceable  in any material  respect in  accordance  with its terms
(except pursuant to the release or termination of any such Subsidiary  Guarantee
in accordance with this  Indenture);  (8) any Collateral  Document shall for any
reason cease to be, or be asserted by the Company,  any  Restricted  Subsidiary,
any of their respective  Affiliates or any Person acting on behalf of any of the
foregoing  not to be, in full force and effect and  enforceable  in any material
respect in accordance  with its terms or to not otherwise grant a duly perfected
first  priority  security  interest in the Collateral in favor of the holders of
the Note Obligations  (subject to Permitted Prior Liens and except pursuant to a
release or termination thereof consummated in accordance with this Indenture and
the Intercreditor  Agreement and other Collateral  Documents) for a period of 30
days after delivery of written  notice  thereof  stating that it is a "notice of
default"  under this  Indenture  and  requiring  the  Company or the  respective
Restricted  Subsidiary,  as the case may be,  to  remedy  the  same;  (9)  final
judgments or orders  rendered  against the Company or any Restricted  Subsidiary
that are unsatisfied and that require the payment in money,  either individually
or in an aggregate amount,  that is more than $2,000,000 over the coverage under
applicable  insurance policies and either (a) commencement by any creditor of an
enforcement  proceeding upon such judgment (other than a judgment that is stayed
by reason of pending  appeal or  otherwise)  or (b) the  occurrence  of a 60-day
period  during  which a stay of such  judgment  or order,  by reason of  pending
appeal or otherwise,  was not in effect;  and (10) certain evens of  bankruptcy,
insolvency or reorganization  of the Company or any Subsidiary,  as the case may
be. If any Event of Default has occurred and is  continuing,  the Trustee or the
Holders of not less than 25% in aggregate  principal  amount of the  Outstanding
Notes may declare the principal of, premium, if any, accrued and unpaid interest
and Liquidated Damages, if any, on the Notes to be due and payable  immediately,
except that (i) in the case of an Event of Default arising from certain evens of
bankruptcy,  insolvency or reorganization of the Company or any Subsidiary,  the
principal  of,  premium,  if any,  accrued and unpaid  interest  and  Liquidated
Damages,  if any, on the Notes will become due and payable  immediately  without
further action or notice.

     The Indenture  contains  provisions  for (i)  defeasance at any time of the
entire  indebtedness of the Company on this Note and (ii) discharge from certain
restrictive  covenants  and the related  Defaults  and Events of  Default,  upon
compliance  by the Company  and  certain  conditions  set forth  therein,  which
provisions apply to this Note.

     Subject to the terms of the Intercreditor Agreement, the Indenture permits,
with certain  exceptions as therein  provided,  the amendment  therefore and the
modification  of the rights and  obligations  of the Company and the  Subsidiary
Guarantors  and the rights of the Holders under the Indenture at any time by the
Company,  the  Subsidiary  Guarantors  and the  Trustee  and the  consent of the
Holders of a majority  in  aggregate  principal  amount of the Notes at the time
Outstanding.  The Indenture also contains  provisions  permitting the Holders of
specified  percentages  in aggregate  principal  amount of the Notes at the time
Outstanding,  on behalf of the Holders of all the Notes, to waive  compliance by
the Company with certain  provisions  of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by or on
behalf  of the  Holder of this Note will be  conclusive  and  binding  upon such

                                  Exhibit A-3
                                       7




Holder and upon all future  Holders of this Note and of any Note issued upon the
registration  of  transfer  hereof or in  exchange  hereof for or in lieu hereof
whether  or not  notation  of such  consent  or waiver  is made upon this  Note.
Without the consent of any Holder,  the Company,  the Subsidiary  Guarantors and
the  Trustee  may amend or  supplement  the  Indenture  or the Notes to cure any
ambiguity,  defect or inconsistency,  to add or release any Subsidiary Guarantor
pursuant to the Indenture, to provide for uncertificated Notes in addition to or
in place of certificated  Notes and to make certain other specified  changes and
other  changes that do not  adversely  affect the interests of any Holder in any
material respect.

     No reference  herein to the  Indenture  and no provision of this Note or of
the  Indenture  will alter or impair the  obligation  of the  Company,  which is
absolute and  unconditional,  to pay the principal of (and premium,  if any, on)

     As provided in the Indenture,  and subject to certain  limitations  therein
set forth, the transfer of this Note is registerable on the Note Register of the

accompanied  by a written  instrument  of transfer in form  satisfactory  to the
Company  and the Note  Registrar  duly  executed  by, the  Holder  hereof or his
attorney  duly  authorized in writing,  and thereupon one or more new Notes,  of
authorized  denominations and for the same aggregate  principal amount,  will be
issued to the designated transferee or transferees.

     The  Notes  are  issuable  only  in  registered  form  without  coupons  in

Indenture and subject to certain  limitations  therein set forth,  the Notes are
exchangeable  for a like  aggregate  principal  amount  of Notes of a  different
authorized denomination, as requested by the Holder surrendering the same.

     No service charge will be made for any registration of transfer or exchange
of Notes,  but the Company may require  payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

the Company or any Subsidiary Guarantor,  as such, past, present or future, will
have any personal  liability  under this Note or the Indenture by reason of his,

or  Affiliate,  or any  liability  for any  obligations  of the  Company  or any
Subsidiary Guarantor under the Notes or the Indenture or for any claim based on,
in respect of, or by reason of such obligations or their creation.  Each Holder,
by  accepting  this Note with the  notation  of  Subsidiary  Guarantee  endorsed
hereon, waives and releases all such liability. Such waiver and release are part
of the  consideration  for the  issuance  of this  Note  with  the  notation  of
Subsidiary Guarantee endorsed hereon.

     Prior  to the  time of due  presentment  of this  Note of  registration  of
transfer, the Company, the Subsidiary  Guarantors,  the Trustee and any agent of
the  Company  or the  Trustee  may treat the  Person in whose  name this Note is

obligations of any Subsidiary  Guarantor under the Notes or the Indenture or for
any claim  based on, in respect  of, or by reason of such  obligations  or their
creation.

     Any Subsidiary Guarantor may be released from its Subsidiary Guarantee upon
the terms and subject to the conditions provided in the Indenture.

of any transfer or assignment of rights by any Holder or the Trustee  respecting
the Note upon which the foregoing  Subsidiary  Guarantees are noted,  the rights
and privileges herein conferred upon that party will automatically extend to and

be  vested  in such  transferee  or  assignee,  all  subject  to the  terms  and
conditions hereof and in the Indenture.

Person and each such account is a  "qualified  institutional  buyer"  within the
meaning of Rule 144A in a transaction  meeting the requirements of Rule 144A and
such Transfer is in compliance  with any applicable  blue sky securities laws of
