constitutes,  and  appoints  the  Collateral  Agent  (and any of the  Collateral
Agent's  officers,  employees or agents  designated by the Collateral  Agent) as
such  Borrower  Party's  true and  lawful  attorney,  with  power to (i) if such
Borrower  Party refuses to, or fails timely to promptly  execute and deliver any
of the documents  described in Section  2.01(h),  sign the name of such Borrower
Party on any of the  documents  described in Section  2.01(h),  (ii) at any time

Party's name on any invoice or bill of lading relating to the Collateral,  draft
against  Account Debtors or notice of Account  Debtors,  (iii) send requests for
verification  of  Accounts,  (iv)  endorse  such  Borrower  Party's  name on any

Agent  determines to be necessary.  The  appointment of the Collateral  Agent as


                                       10


such Borrower Party's attorney, and each and every one of its rights and powers,
being  coupled  with  an  interest,  is  irrevocable  until  all of the  Secured
Obligations  have been fully and finally repaid and performed and, to the extent
applicable,  the Secured  Parties'  obligations to extend credit  thereunder are
terminated.  Notwithstanding  the  foregoing  sentence,  if at any time or times
after the Final  Termination  Date, any Secured Party shall be required to repay
any amount  previously paid by or on behalf of the Borrower Parties by virtue of
an order of any court having jurisdiction in the premises, including as a result
of an  adjudication  that such  amounts  constituted  preferential  payments  or
fraudulent  conveyances,  then the power of  attorney  granted  by this  Section
2.01(i) shall be reinstated.

     (j) Right to Inspect.  The Collateral Agent and each Secured Party (through
any of their  respective  officers,  employees or agents)  shall have the right,
upon  notice  to the  Borrower,  which  notice  shall not be  required  upon the

such Borrower  Party,  the  Collateral  Agent,  and the substitute  bank,  other
financial  institution  or securities  intermediary  have entered into a Control
Agreement. Each Borrower Party hereby agrees to take any and all action that the
Collateral Agent requests in order for the Collateral Agent to obtain control in
accordance with the UCC, including Sections 9-104, 9-105, 9-106 and 9-107 of the
UCC, as applicable,  with respect to any Securities Accounts or other Investment
Property, or any DDA, chattel paper or letter-of-credit  rights. No arrangements
contemplated  hereby or by any Control  Agreement  in respect of any  Securities
Accounts  or  other   Investment   Property,   or  any  DDA,  chattel  paper  or
letter-of-credit  rights  shall be modified by any  Borrower  Party  without the
prior written  consent of the Collateral  Agent.  During a Default  Period,  the
Collateral  Agent may notify any bank, other financial  institution,  securities
intermediary  or depository to liquidate the  applicable  Securities  Account or
DDA, or any  Investment  Property  maintained or held thereby,  and to remit the
proceeds  of  the  Securities   Account  or  DDA  to  the  Collateral   Account.
Notwithstanding  anything to the contrary herein, the Secured Parties agree that
the Borrower  Parties shall not be required to deliver to the  Collateral  Agent
Control Agreements in connection with any Securities Accounts or DDAs which have
a balance of $25,000 or less, in the aggregate.

Financing Agreements and the Trust Indenture Act:

result from any of the foregoing  activities,  individually or in the aggregate,
which is proposed to be  undertaken,  and (z) any of the  foregoing  activities,
individually or in the aggregate,  which is proposed to be undertaken  would not
violate this Agreement and the other Security Documents.

     (c) The  Borrower  shall  deliver to the  Collateral  Agent and each Agent,

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

of an  Authorized  Asset  Disposition  Certificate  from a Borrower  Party,  the
Collateral  Agent  shall  execute  and  deliver  on or before the  Release  Date
(subject to consummation of such Authorized Asset  Disposition) such instruments
of release from the Security Interests as the Borrower may reasonably request to
effectuate the release of the Affected Assets (each, a "Release"),  and any such
Release so executed and delivered  shall be fully binding on the Secured Parties
and the Collateral Agent; provided, however, that the Collateral Agent shall not
release any Collateral pursuant to this Section 2.03(b) if, prior to the Release
Date,  any Agent shall have delivered  written  notice to the  Collateral  Agent
(with a copy to the  Borrower)  that the  release of such  Collateral  is not in
compliance in any material  respect with the Financing  Agreements to which such

deliver  such  instruments  as the  Control  Party  may  reasonably  request  to
effectuate  the sale of  Collateral  and the release of such  Collateral so sold

Date, the Security Interests and the rights, remedies, powers, duties, authority
and  obligations  conferred upon the Secured  Parties and the  Collateral  Agent
pursuant to this Agreement shall terminate and be of no further force and effect
and all rights,  remedies,  powers,  duties,  authority and  obligations  of the
Secured Parties and the Collateral Agent with respect to the Collateral shall be
automatically released in favor of the Borrower Parties; provided, however, that
each of the Secured Parties and the Collateral Agent, if requested in writing by
the  Borrower  and  at  Borrower's  expense,  shall  execute  and  deliver  such
instruments  of release in favor of the  Borrower  Parties as the  Borrower  may

creditors,  nor by any other action or inaction which any Agent or Secured Party

Parties consents to the Borrower  Parties'  Granting to each other Secured Party
the Liens and Security Interests provided for in this Article II.

     Section 2.06.  Marshaling.  None of the Secured  Parties or the  Collateral

Borrower  Party or any other party or against or in payment of any or all of the
Secured Obligations.

and  replacements  so that at all times the state and conditions of such Oil and
Gas Properties and other material assets will be fully preserved and maintained,

Account  or any funds on  deposit  therein,  or  otherwise  to the credit of the
Collateral  Agent Account,  shall become subject to any writ,  order,  judgment,
warrant of  attachment,  execution  or similar  process.  Neither  the  Borrower

of this Agreement.

     (d) All payments to be made by the Collateral Agent hereunder shall be made
only from amounts available in the applicable  Collateral Agent Account. Each of
the Secured  Parties  hereby agrees to look solely to such amounts to the extent
available for  distribution  to it as provided in this  Agreement,  and that the
Collateral Agent is not personally liable to any of them for any amounts payable
or any liability under this Agreement or any other Financing  Agreement,  except

Borrower.  In the absence of written  directions to the  Collateral  Agent,  the

applicable  Collateral  Agent Account when received by the Collateral  Agent and
shall be applied by the Collateral Agent in the same manner as the other amounts
on deposit in such  Collateral  Agent Account are to be applied.  The Collateral
Agent's  reasonable fees and expenses in making such  investments and any losses
incurred  in such  investments  shall be charged  against the  principal  amount
invested.  The Collateral  Agent shall not be liable for any loss resulting from
any  investment,  reinvestment  or  liquidation  required  to be made under this

Eligible  Investments  and any other  investment  required to be made  hereunder
shall be held to their  maturities  except that any such  investment may be sold
(without  regard to its maturity) by the Collateral  Agent without  instructions
whenever  such sale is  necessary  to make a  distribution  required  under this
Agreement. Uninvested funds held hereunder shall not earn or accrue interest.

information  set  forth in  Section  4.06(a)  that is  required  to  enable  the
Collateral  Agent to make a  distribution  to such  Person  pursuant  to Section
4.06(b),  the Collateral Agent shall not make such  distribution to such Person.
In such event, the Collateral Agent shall make  distributions  pursuant to other
clauses of Section 4.06(b) to the extent it shall have sufficient information to
enable  it to make such  distributions,  and  shall  continue  to hold any funds
remaining,  after making such  distributions,  until the Collateral  Agent shall
receive  all  necessary  information  to  enable it to  distribute  any funds so
withheld,  and upon receipt of the information necessary to distribute any funds
so withheld, the Collateral Agent shall distribute such funds accordingly.

discontinuation  of a Default Period,  the Borrower Parties shall be entitled to
receive  and  disburse  such funds in  accordance  with the  provisions  of this
Section 4.07.

payment or distribution of property or assets of any Borrower Party,  whether in

                                   ARTICLE V

                              THE COLLATERAL AGENT

     Section 5.01.  Appointment and Powers.  Subject to the terms and conditions
hereof,  each  of  the  Secured  Parties  hereby  appoints  U.S.  Bank  National
Association as the Collateral  Agent and U.S. Bank National  Association  hereby
accepts such  appointment and agrees to act as Collateral  Agent for the Secured
Parties and to perform the duties of the Collateral Agent in accordance with the
provisions  of  this  Agreement.   Each  Secured  Party  hereby  authorizes  the
Collateral  Agent to take such action on its behalf and to exercise such rights,
remedies,  powers and privileges hereunder as are specifically  authorized to be
exercised  by the  Collateral  Agent by the  terms  hereof,  together  with such
rights, remedies, powers and privileges as are reasonably incidental thereto.

     Section 5.02. Performance of Duties.

     (a) If the  Collateral  Agent  receives a request to take action or consent
under  any  of the  Financing  Agreements  that  is  not  expressly  authorized,
permitted or required by this Agreement,  the Collateral Agent shall immediately
request  direction from the Control Party.  Except as  specifically  provided in
this  Agreement,  the  Collateral  Agent  shall not take any  action  under this
Agreement or any other Financing  Agreement without the direction of the Control
Party.

     (b) The Collateral Agent may perform any of its duties  hereunder  directly
or by or through  agents or  employees  and shall be  entitled  to consult  with
counsel  and to act in  reliance  upon the  advice  of such  counsel  concerning
matters pertaining to the agencies created hereby and its duties hereunder,  and
shall not be liable  for any  action  taken or omitted to be taken by it in good
faith and in  reasonable  reliance  upon and in  accordance  with the  advice of
counsel  selected by it. The  Collateral  Agent  undertakes to perform only such
duties  as  are  expressly  set  forth  herein,  and  no  implied  covenants  or
obligations  shall be read into this Agreement  against the Collateral Agent. No
provision of this Agreement  shall be construed to relieve the Collateral  Agent
from liability to the Secured  Parties,  or any of them, or the Borrower for its


                                       25


own gross  negligence or willful  misconduct,  provided that: (i) the Collateral
Agent shall not be liable with respect to any action taken,  suffered or omitted
by it in good faith (A) reasonably believed by it to be authorized or within the
discretion  or rights or powers  conferred  on it by this  Agreement,  or (B) in
accordance  with any written  direction or request of the Secured Parties (other
than those that  require the consent of other  parties and such consent has been
withheld),  unless in either case the Collateral Agent was grossly  negligent in
ascertaining  the  pertinent  facts or  grossly  negligent  in  determining  the
requirements imposed by this Agreement or such written direction or request; and
(ii) the Collateral  Agent shall not be liable for any error of judgment made in
good faith by any of its officers or employees,  unless the Collateral Agent was
grossly  negligent in  ascertaining  the pertinent  facts or in determining  the
requirements imposed by this Agreement.

     (c) Anything in this Agreement to the contrary notwithstanding, in no event
shall the Collateral  Agent be liable under or in connection with this Agreement
for indirect, special,  incidental,  punitive or consequential losses or damages
of any kind whatsoever,  including,  but not limited to lost profits, whether or
not  foreseeable,  even  if  the  Collateral  Agent  has  been  advised  of  the
possibility  thereof and  regardless of the form of action in which such damages
are sought; provided,  however, that this clause shall not be deemed to apply in
the event of a finding by a court of competent  jurisdiction of gross negligence
or willful misconduct on the part of the Collateral Agent.

     Section 5.03. Reliance Upon Documents.

     (a) In the absence of bad faith on its part, the  Collateral  Agent (i) may
conclusively  rely, as to the truth of the statements and the correctness of the
opinions  expressed  therein,  upon  any  note,  notice,  resolution,   consent,
certificate,  affidavit, letter, telegram, teletype message, statement, order or
other document  reasonably  believed by it to be genuine and correct and to have
been signed or sent by the proper Person or Persons, (ii) shall not be obligated
to make any  investigation  into facts or matters stated in any such document or
instrument  and (iii) shall have no liability in acting,  or in omitting to act,
where such  action or  omission  to act is in  reliance  upon any  statement  or
opinion  contained in any such  document or  instrument.  The  Collateral  Agent
assumes no  responsibility  or liability for (i) the correctness of the recitals
to this Agreement,  or (ii) the validity,  execution (except its own execution),
effectiveness, value, sufficiency, enforceability or legality of this Agreement,
or the other  Financing  Agreements or of the  Collateral (or any part thereof).
The Collateral Agent shall have no  responsibility  for maintaining the value of
the  Collateral or,  ensuring that any  Collateral is properly  delivered to it,
provided  that  the  Collateral  Agent  shall be  responsible  for  holding  the
Collateral in accordance with the provisions  hereof. The Collateral Agent shall
take or cause to be taken all  action  recommended  pursuant  to any  Opinion of
Counsel  received by the Collateral  Agent as may be necessary or appropriate to
perfect and protect the Security Interests granted hereby.

     (b)  Notwithstanding  any provision to the contrary contained in Article V,
in  performing  its  obligations  to transfer  amounts and make  payments to any
Person in accordance  with Article IV, the Collateral  Agent is entitled to rely
upon the information  furnished to it by the Agents pursuant to Sections 4.05(a)
and 4.06(a).

     (a) Merger.  Any Person into whom the Collateral  Agent may be converted or
merged,  or with  which  it may be  consolidated,  or to  which  it may  sell or
transfer its trust business and assets as a whole or  substantially  as a whole,
or any Person resulting from any such conversion, sale, merger, consolidation or
transfer  to  which  the  Collateral  Agent is a party,  shall  (provided  it is
otherwise  qualified to serve as the Collateral Agent hereunder) be and become a
successor  Collateral Agent hereunder and be vested with all of the title to the
Collateral and all of the trusts, powers,  discretions,  immunities,  privileges
and other matters as was its predecessor  without the execution or filing of any
instrument  or any further  act,  deed or  conveyance  on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

     (b) Resignation.  The Collateral  Agent and any successor  Collateral Agent
may at any  time  resign  by  giving  60 days'  written  notice  by  registered,
certified  or express  mail to each  Agent,  the  Borrower  and each  Guarantor;
provided,  that such  resignation  shall take effect only upon the date which is
the later of the effective  date of the  appointment  of a successor  Collateral
Agent  pursuant to  paragraph  (d) below and the  acceptance  in writing by such
successor  Collateral Agent of such appointment and of its obligation to perform
its duties  hereunder in accordance with the provisions  hereof.  Subject to the
preceding  sentence,  if on the 60th day after written  notice of resignation is
delivered  by a  resigning  Collateral  Agent as  described  above no  successor
Collateral Agent or temporary  successor  Collateral Agent has been appointed in
accordance  herewith,  the  resigning  Collateral  Agent may petition a court of
competent jurisdiction in New York City for the appointment of a successor.

     (c)  Removal.  At any time other than after the  occurrence  and during the
continuation  of an Event of Default  (but not more than once in any twelve (12)
month  period),  the Borrower may remove the Collateral  Agent,  with or without
cause, by an instrument delivered to the Collateral Agent and the Agents. At any
time after the  occurrence and during the  continuation  of an Event of Default,
the Control Party may remove the Collateral  Agent, with or without cause, by an
instrument delivered to the Borrower, the other Agents and the Collateral Agent.
A temporary successor may be removed at any time to allow a successor Collateral
Agent to be appointed  pursuant to paragraph (d) below.  Any removal pursuant to
the  provisions of this paragraph (c) shall take effect only upon the date which
is the latest of the effective date of the appointment of a successor Collateral
Agent appointed pursuant to paragraph (d) below and the acceptance in writing by
such successor  Collateral  Agent of such  appointment  and of its obligation to
perform its duties hereunder in accordance with the provisions hereof.

     (d) Acceptance by Successor. Any successor Collateral Agent shall be a bank
or trust company (i) having its principal  office in New York, New York, or such
other jurisdiction as the Secured Parties may approve by Majority Vote, and (ii)
having a  shareholders'  or owners'  equity of at least  $500,000,000  as of the
effective date of appointment.  No successor  Collateral  Agent can be an Agent.
The Secured  Parties by Majority  Vote shall have the sole right to appoint each
successor  Collateral  Agent,  subject only to the requirements set forth in the
preceding  sentence.  If the Secured  Parties  shall not have agreed by Majority
Vote within ten days as to the selection of a successor  Collateral  Agent,  the
Control  Party shall have the right to appoint a temporary  successor  to act as
the  Collateral  Agent.  If by the 90th day after  appointment of such temporary
successor  Collateral  Agent,  the Secured  Parties by Majority  Vote shall have
remained  unable to agree by Majority  Vote as to the  selection  of a successor
Collateral  Agent,  such  temporary  successor  shall  automatically  become the
successor  Collateral  Agent hereunder.  Every temporary or permanent  successor


                                       27


Collateral Agent appointed  hereunder shall execute,  acknowledge and deliver to
its  predecessor  and to the Agents and the  Borrower an  instrument  in writing
accepting such appointment hereunder and the relevant predecessor shall execute,
acknowledge  and deliver such other documents and instruments as will effectuate
such  appointment,  whereupon such  successor,  without any further act, deed or
conveyance, shall become fully vested with all the estates, properties,  rights,
powers, duties and obligations of its predecessors.

     Section 5.05.  Indemnification.  The Borrower  Parties  shall,  jointly and
severally,  indemnify the Collateral  Agent and the Control  Party,  each of its
officers,  employees and its agents for, and hold the Collateral  Agent and each
of its officers, employees and its agents harmless against, any loss, liability,
damage,  claim,  action,  demand or expense (including the costs and expenses of
defending  against any claim of liability)  arising out of or in connection with
the performance of its duties hereunder,  except such loss,  liability,  damage,
claim, action,  demand or expense as shall result from their gross negligence or
willful  misconduct.  The obligation of the Borrower  Parties under this Section
shall survive the  termination of this Agreement and the  resignation or removal
of the Collateral Agent.

     Section 5.06.  Compensation and  Reimbursement.  The Borrower agrees (a) to
pay to the  Collateral  Agent  from time to time,  reasonable  compensation  (as
separately  agreed between the Borrower and  Collateral  Agent) for all services
rendered by it  hereunder,  and (b) to reimburse the  Collateral  Agent upon its
request for all reasonable expenses, disbursements and advances incurred or made
by the Collateral Agent in accordance with any provision of, or carrying out its
duties  and  obligations   under,  this  Agreement   (including  the  reasonable
compensation  and fees and the expenses  and  disbursements  of its agents,  any
certified   public   accountants  and  legal   counsel),   except  any  expense,
disbursement or advance as may be attributable to gross negligence, bad faith or
willful misconduct on the part of the Collateral Agent.

     Section 5.07.  Representations  and Warranties of the Collateral Agent. The

     Section   6.01.   Exercise   of   Remedies;   Management   of   Collateral.
Notwithstanding  anything  to the  contrary  contained  in any of the  Financing
Agreements:

     (a) The  Control  Party  shall  have  the  exclusive  right to  direct  the
Collateral  Agent to  manage,  perform  and  enforce  the terms of the  Security
Documents  with  respect to the  Collateral  and to  exercise  and  enforce  all
privileges and rights thereunder in their sole discretion,  including (i) taking
or retaking  control or possession of  Collateral,  (ii) holding,  preparing for
sale, processing,  selling,  leasing,  disposing of and liquidating  Collateral,

and remedies in  accordance  with this  Agreement,  the  Collateral  Agent shall
diligently  pursue in good faith the exercise and  enforcement  of its rights or
remedies against such Collateral in a commercially reasonable manner designed to
maximize the value to be obtained from such  Collateral and in any sale or other
disposition of any of such  Collateral by the Collateral  Agent,  the Collateral
Agent shall conduct such sale or other disposition in a commercially  reasonable
manner. Except as provided in this Agreement,  no other parties to the Financing
Agreements  shall have the right to exercise or to instruct the Collateral Agent
to exercise any rights or remedies under the Security  Documents or with respect
to Collateral or commence,  or join with any other creditor in  commencing,  any
Bankruptcy Case.

     (b)  Except  as  provided  in  this  Agreement,  any and  all  proceeds  of

Borrower Party or any Secured Party will be deemed to have been received for the

immediately  paid to the  Collateral  Agent  for  deposit  into  the  applicable
Collateral Agent Account for distribution pursuant to Article IV.

     (c) The Secured  Parties,  by their  extension of financing to the Borrower
evidenced by the Financing  Agreements,  each hereby agree that, with respect to
any  Financing  Agreement at any time during a Default  Period,  the Agents will
each be directed in exercising, or refraining from exercising,  any action under
such applicable  Financing  Agreement with respect to the Collateral,  including
exercising  remedies of a secured party  thereunder,  by the Collateral Agent as
directed by the Control Party.

                                       31


     (d) The rights and  priorities  set forth in this  Agreement  shall  remain
binding  irrespective of the terms of any plan of reorganization in a Bankruptcy
Case or other  provisions of the Bankruptcy Code or any similar federal or state
statute.

     Section 6.02. Control Party.


     (a) At all times other than during a Default  Period,  the "Control  Party"
shall be the Senior Secured Parties acting by Majority Vote.

     (b) Upon the  commencement of a Default Period and for a period of 240 days
following such commencement  (the "Initial Control  Period"),  the Control Party
shall be the Junior  Secured  Parties  acting by Majority  Vote. If, by the last
Business Day during the Initial Control Period,  the Senior  Indebtedness  shall
not have  been Paid in Full,  the  Control  Party  shall be the  Senior  Secured
Parties  acting by Majority  Vote;  provided,  however,  that if, within 15 days
prior to the end of the Initial Control  Period,  the Junior Secured Parties pay
or  cause  to be paid to the  Senior  Secured  Parties  an  amount  equal to the
outstanding Senior Indebtedness (and cause the Senior Indebtedness to be Paid in
Full),  then the Junior  Secured  Parties shall remain the Control Party and the
Junior  Secured  Parties will be  subrogated  to all of the rights of the Senior
Secured  Parties,  including  the right to payment  on the Senior  Indebtedness;
provided  further,  that the Initial  Control Period shall be tolled during such
time as the  Collateral  Agent is stayed from  enforcing its Liens on a material
portion of the Collateral to the extent the Collateral  Agent,  on behalf of the
Control Party, used reasonable  efforts to attempt to vacate such stay or made a
reasonable  determination  that any such  action to vacate  such stay would have
been without merit.

     (c) After the Senior Indebtedness shall have been Paid in Full, the Control
Party shall at all times be the Junior Secured Parties acting by Majority Vote.

     (d) The  Collateral  Agent  shall give  written  notice to all of the other
parties to this Agreement  promptly upon a change in the identity of the Control
Party.  Each of the parties  hereto agrees that it shall not exercise any of the
rights  of the  Control  Party  at  such  time as it is not  the  Control  Party
hereunder.  In the absence of bad faith on its part,  the  Collateral  Agent may
conclusively rely, and will be fully protected in so relying,  on (i) statements
as to the  identity of the Control  Party and (ii) on any  direction,  waiver or
consent of the Control Party.

     (e) This  Article VI shall not be  construed  in any way to limit or impair
the right of any Secured Party to bid for and purchase Collateral at any private
or judicial foreclosure upon such Collateral initiated by any Secured Party.

     Section 6.03. Rights and Remedies.

     (a) Remedies Under the Debt  Documents.  The Control Party shall direct the
Collateral  Agent,  which in turn  shall  direct  the  Agents  under  each  Debt
Document, in the exercise of remedies available pursuant to such Debt Document.

Period,  the Control Party may authorize and instruct the Collateral Agent to do
any  one or  more  of the  following  on  behalf  of the  Secured  Parties  (and
Collateral  Agent,  acting upon the instructions of the Control Party,  shall do


                                       32


the same on behalf of the Secured  Parties),  all of which are authorized by the

                                       34


     (a) This  Agreement  shall  continue  in full  force and  effect  after the
commencement  of a Bankruptcy Case (all  references  herein to Borrower  Parties
being  deemed to apply to  Borrower  Parties  as  debtor-in-possession  and to a
trustee for Borrower Parties' estate in a Bankruptcy Case), and shall apply with
full force and effect with respect to all  Collateral  acquired by such Borrower
Parties,  and to all Secured Obligations incurred by Borrower Parties subsequent
to such  commencement  (it  being  understood  that the  relative  rights of the
Secured Parties in or to any distributions  from or in respect of any Collateral
or proceeds of Collateral as provided in this Agreement shall continue after the
commencement of a Bankruptcy Case on the same basis as prior to the date of such
commencement),  subject to any court order approving the financing of, or use of
cash  collateral  by, the  Borrower or any Obligor as  debtor-in-possession.  In
furtherance of the foregoing,  the Junior Secured Parties  acknowledge and agree
that, in the event of a distribution of debt or equity  securities  under a plan
of  reorganization   under  any  Bankruptcy  Case  in  satisfaction  of  Secured
Obligations (such securities, "Reorganization Securities") to each of the Senior
Secured Parties and the Junior Secured Parties,  such Reorganization  Securities
received  by  the  Junior  Secured   Parties  shall  be   subordinated   to  the
Reorganization  Securities  received by the Senior  Secured  Parties to the same
extent that the Junior  Indebtedness is subordinated to the Senior  Indebtedness
pursuant to the terms of this Agreement.

     (b) If any Borrower Party shall become subject to a Bankruptcy  Case and if
as  debtor-in-possession   moves  for  approval  to  obtain  financing  (a  "DIP
Financing") to be provided in good faith by the parties to the Revolving  Credit
Facility (the "DIP Lender") under Section 364 of the Bankruptcy  Code (including
the use of cash  collateral  with the  consent  of the DIP  Lender),  the  other
Secured  Parties  agree that (i) adequate  notice to the other  Secured  Parties
shall be  deemed  to have  been  provided  for such DIP  Financing  if the other
Secured  Parties  receive notice thereof in a manner  prescribed in Section 8.02
prior to any  hearing  on a request to approve  such DIP  Financing  and (ii) no
objection  shall be raised by it to any such DIP  Financing  on the grounds of a
failure  to  provide  "adequate  protection"  for its  Liens  so long as (A) the
Collateral  Agent for the benefit of the Secured  Parties  retains a Lien on the
Collateral  (including  proceeds  thereof arising after the commencement of such
proceeding)  with the same priority as existed prior to the commencement of such
Bankruptcy Case, (B) the Collateral Agent for the benefit of the Secured Parties
receives a replacement Lien on  post-petition  assets to the same extent granted
to the DIP Lender,  with the same priority as existed prior to the  commencement
of such Bankruptcy Case, (C) the aggregate principal amount of the DIP Financing
(which shall have a superpriority  administrative expense claim status and first
lien  priority) will not exceed the lesser of (x) the Maximum  Revolver  Amount,
plus any Related Revolving Credit Facility Indebtedness, and (y) the outstanding
pre-petition  Revolving Credit Facility Indebtedness  (including any obligations
outstanding under Bank Product  Agreements) plus $5,000,000,  (D) the Collateral
Agent for the benefit of each of the Secured Parties shall receive superpriority
administrative  expense claim status to the extent of any diminution of value of
the   Collateral   available  to  such  Secured  Party,   subordinated   to  the
superpriority administrative expense claim status of the DIP Lender and with the
same priority among the Secured Parties as existed prior to the  commencement of
the Bankruptcy  Case, and (E) such DIP Financing is subject to the terms of this
Agreement.  Nothing  contained herein shall be deemed to limit the rights of the
other Secured  Parties to object to the DIP Financing or use of cash  collateral
on any grounds other than the failure to provide  "adequate  protection" for its
Liens.

                                       35


     (c) Each of the Secured  Parties  shall not,  directly or  indirectly,  (i)
challenge or contest the validity or  enforceability of this Agreement or any of
the Financing Agreements,  (ii) challenge or contest the exercise of any rights,
remedies or duties of the Control  Party in accordance  with this  Agreement and
the  applicable  Financing  Agreements,  or (ii)  take  any  action  that  would
reasonably be expected to restrain,  hinder, limit, delay or otherwise interfere
in any  material  respect  with the  exercise  of the  rights  or  duties of the
Collateral Agent in accordance with this Agreement.

     Section 6.05. Notice of Default and Certain Events.

     (a) The Borrower  Parties shall promptly send to the  Collateral  Agent and
each Agent written  notice of any default under any of the Financing  Agreements
or any Event of Default,  and shall promptly provide to the Collateral Agent and
each Agent  copies of any  notices  (other  than  periodic  reports  and advance
requests)  received from or delivered by any Borrower Party to any Secured Party
in connection with any of the Financing Agreements.

     (b) The Collateral Agent will promptly provide to the Agents written notice
of any action taken by the Collateral  Agent with respect to its  obligations or
duties under this  Agreement,  including  action taken at the instruction of the
Control Party,  and shall promptly provide the Agents with copies of any notices
received  from or  delivered  to any  Borrower  Party in  connection  with  this
Agreement.

     Section  6.06.  Remedies  Cumulative.  Subject  always  to  the  terms  and
conditions  hereof,  each and every right, power and remedy given to the Secured
Parties, the Collateral Agent and the Control Party specifically or otherwise in
this Agreement or the other Financing  Agreements  shall be cumulative and shall
be in addition to every other right, power and remedy herein  specifically given
or now or hereafter existing at law, in equity or by statute, and each and every
right, power and remedy whether  specifically herein given or otherwise existing
may be  exercised  from  time to time and as often  and in such  order as may be
deemed expedient by any Agent, the Secured Parties,  the Collateral Agent or the
Control Party, as appropriate, and the exercise or the beginning of the exercise
of any right, power or remedy shall not be construed to be a waiver of the right
to exercise at the same time or thereafter any other right,  power or remedy. No
delay or omission by any Agent, the Secured Parties, the Collateral Agent or the
Control Party in the exercise of any right, remedy or power or in the pursuit of
any remedy shall impair any such right,  power or remedy or be construed to be a
waiver of any default or to be an acquiescence therein.

     Section 6.07. The  Collateral  Agent's and Secured  Parties'  Liability for
Collateral.  The Borrower Parties hereby agree that (a) the Collateral Agent and
the Secured  Parties shall not in any way or manner be liable or responsible for
(i) the safekeeping of the Collateral, (ii) any loss or damage thereto occurring
or arising in any manner or fashion from any cause,  (iii) any diminution in the
value thereof, or (iv) any act or default of any carrier, warehouseman,  bailee,
forwarding  agency  or  other  Person,  and (b)  all  risk of  loss,  damage  or
destruction  of the  Collateral  shall be borne  jointly  and  severally  by the
Borrower Parties.

                                       36


     Section  6.08.  Amounts  Collected.  Any and all proceeds  collected by the
Collateral  Agent in the  exercise  of remedies  under this  Article VI shall be
deposited in the Collateral Account and distributed pursuant to Section 4.06.

     Section  6.09.  Appraisals.  At the  request  of  the  Control  Party,  the
Collateral  Agent may from time to time during a Default  Period  commission  an
appraisal with respect to the Collateral or any portion thereof.  The Collateral
Agent  shall not be required  to  commission  such  appraisal  unless  there are
sufficient  funds in the Collateral  Account to cover the cost of such appraisal
or, if such funds are not  sufficient,  the Control  Party (or any other Secured
Party) shall have agreed to reimburse the Collateral  Agent for the cost of such
appraisal.

     Section 6.10. Reinstatement. If any Senior Secured Party is required in any
Bankruptcy  Case or  otherwise  to turn  over or  otherwise  pay any  amount  (a
"Recovery")  to the estate or to any  creditor or  representative  of a Borrower
Party or any other Person,  then the Senior  Indebtedness shall be reinstated to
the extent of such Recovery.  If this Agreement shall have been terminated prior
to such Recovery,  this Agreement  shall be reinstated in full force and effect,
and such prior termination shall not diminish,  release,  discharge,  impair, or
otherwise  affect  the  obligations  of the  parties  hereto  from  such date of
reinstatement.  All rights, interests, agreements and obligations of the Secured
Parties under this  Agreement  shall remain in full force and effect,  and shall
continue  irrespective of the commencement  of, or any discharge,  confirmation,
conversion, or dismissal of any Bankruptcy Case by or against any Borrower Party
or any other Person and irrespective of any other  circumstance  which otherwise
might constitute a defense available to, or a discharge of any Borrower Party or
any other Person in respect of the Senior Indebtedness.  No priority or right of
the Senior Secured Parties or any other holder of Senior  Indebtedness  shall at
any time be  prejudiced  or  impaired in any way by any act or failure to act on
the part of any Borrower  Party or any other Person or by the  noncompliance  by
any Person with the terms, provisions, or covenants of the Financing Agreements,
regardless of any  knowledge  thereof  which the Senior  Secured  Parties or any
holder of Senior Indebtedness may have.

     Section 6.11. Trust Indenture Act.  Notwithstanding  any other provision of
this Article VI, the right of any Noteholder to receive payment of the principal
of and interest on the Notes,  on or after the respective due dates expressed in
the Notes,  or to institute  suit for the  enforcement of any such payment on or
after such  respective  dates,  shall not be impaired  or  affected  without the
consent of such holder.

Senior Indebtedness shall have been Paid in Full, no payment in cash, securities
or other property  (excluding (i) securities that are subordinated to the Senior
Indebtedness to the same extent as, or more deeply than, the Junior Indebtedness
is subordinated to the Senior  Indebtedness  pursuant to this Agreement and (ii)
Grey Wolf Capital Stock or any proceeds  thereof)  shall be made by or on behalf
of the Borrower Parties with respect to any Junior  Indebtedness  and, except as

provided in this Agreement, the Junior Secured Parties will not ask, demand, sue
for,  take or receive  any such  payment,  directly  or  indirectly,  out of the
proceeds of the Collateral from or on behalf of the Borrower Parties,  if at the
time of such payment or immediately after giving effect thereto there shall have
occurred and be continuing an Event of Default with respect to any of the Senior
Documents  which  arises out of the failure to make any payment  with respect to
any  Senior  Indebtedness.  If at any time  following  a  blockage  of  payments
pursuant  to this  Section  7.01  holders of Junior  Indebtedness  are no longer
prohibited by this Section 7.01 from  receiving any payments with respect to the
Junior Indebtedness, such holders shall be entitled to receive, and the Borrower

7.01, any payment or distribution  of assets of any Borrower  Party,  whether in

in trust  for the  benefit  of and  shall be paid  over to or  delivered  to the
Collateral  Agent for  distribution  pursuant to Section 4.06,  until all Senior
Indebtedness shall have been Paid in Full.

its behalf to take such action as may be necessary or  appropriate to effectuate
the  subordination  provided in this Agreement and appoints the Collateral Agent
its attorney-in-fact for any and all such purposes.

     Section 7.04. No Waiver of Subordination Provisions. No right of the Senior
Secured  Parties or the  Collateral  Agent to enforce the  subordination  of the
Junior  Indebtedness  as  herein  provided  shall  at any  time  in  any  way be
prejudiced  or impaired by any act or failure to act on the part of any Borrower
Party or any of the Senior  Secured  Parties or the  Collateral  Agent or by any
non-compliance by any Borrower Party with the terms, provisions and covenants of
this Agreement or any other Financing Agreement.
