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

("Borrower"),  Revolving  Lenders,  and Bank One,  NA,  with its main  office in
Chicago,  Illinois, as Administrative Agent thereunder  ("Revolving Agent"), are
parties to that certain Credit Agreement (as amended, restated,  supplemented or
otherwise modified from time to time, the "Revolving Credit  Agreement";  unless
otherwise defined or indicated herein,  all terms used herein with their initial
letter  capitalized  shall have the  meaning  given such terms in the  Revolving
Credit  Agreement)  dated as of December 22, 2003,  pursuant to which  Revolving
Lenders have agreed to make a revolving loan to Borrower and agreed to issue and
participate in letters of credit issued on behalf of Borrower; and

      WHEREAS,  Borrower,  Guarantor,  Term Lenders,  and Bank One, NA, with its
main  office in Chicago,  Illinois,  as Agent  thereunder  ("Term  Agent"),  are
parties to that certain  Senior Term Second Lien Secured  Credit  Agreement  (as
amended,  restated,  supplemented  or otherwise  modified from time to time, the
"Term Credit Agreement" and,  together with the Revolving Credit Agreement,  the
"Credit  Agreements" and, each individually,  a "Credit  Agreement") dated as of
December  22,  2003,  pursuant to which Term  Lenders have agreed to make a term
loan to Borrower; and

      WHEREAS,  certain of the relative rights and remedies of Revolving Lenders
and  Term  Lenders  are  set  forth  in  that  certain   Collateral  Agency  and
Intercreditor  Agreement  dated as of December  22, 2003 among Bank One,  NA, as
Collateral Agent thereunder  ("Collateral Agent"),  Revolving Agent, Term Agent,
Noteholders,  Borrower and  Guarantor  (as amended,  restated,  supplemented  or
otherwise modified from time to time, the "Intercreditor Agreement"); and

      WHEREAS,  pursuant  to the terms of the  Credit  Agreements,  Borrower  is
obligated to deliver this Guaranty executed by Guarantor; and

      WHEREAS,  the board of directors of Guarantor has determined that valuable
benefits  will be  derived by it as a result of the  Credit  Agreements  and the
extension of credit made (and to be made) by Noteholders thereunder; and

                                       1
<PAGE>

      WHEREAS,   the  board  of  directors  of  Guarantor  has  determined  that
Guarantor's execution,  delivery and performance of this Guaranty may reasonably
be  expected  to benefit  Guarantor,  directly  or  indirectly,  are in the best
interests  of  Guarantor,  and  are  necessary  or  convenient  to the  conduct,
promotion or attainment of Borrower's business; and

      WHEREAS, Guarantor has further determined that the benefits accruing to it
from each Credit Agreement exceed Guarantor's  anticipated  liability under this
Guaranty.

      NOW, THEREFORE, for valuable consideration, the receipt and sufficiency of
which are hereby  acknowledged  and confessed,  Guarantor  hereby  covenants and
agrees as follows:

     1. Guarantor hereby absolutely and  unconditionally  guarantees the prompt,
complete  and full payment when due, no matter how such shall become due, of the
Obligations,  and further  guarantees  that  Borrower  will  properly and timely
perform  the  Obligations.   Notwithstanding  any  contrary  provision  in  this
Guaranty, however, Guarantor's maximum liability under this Guaranty is limited,
to the  extent,  if any,  required  so that  its  liability  is not  subject  to
avoidance  under  applicable  Debtor  Relief  Laws (as such term is  defined  in
Paragraph 8 hereof). As used herein, "Obligations" shall mean, collectively, all
Obligations,  as such term is defined in the Revolving Credit Agreement, and all
Obligations, as such term is defined in the Term Credit Agreement.

     2. If Guarantor is or becomes liable for any indebtedness owing by Borrower
to any Noteholder by  endorsement  or otherwise  than under this Guaranty,  such
liability shall not be in any manner impaired or affected hereby, and the rights
of  Noteholders  hereunder  shall be cumulative of any and all other rights that
Noteholders may ever have against  Guarantor.  The exercise by any Noteholder of
any  right or remedy  hereunder  or under  any  other  instrument,  at law or in
equity,  shall not preclude the  concurrent or subsequent  exercise of any other
right or remedy.

     3. In the event of default by  Borrower in payment of the  Obligations,  or
any part thereof,  when such Obligations become due, either by their terms or as
the result of the  exercise  of any power to  accelerate,  Guarantor  shall,  on
demand,  and without  further  notice of dishonor and without any notice  having
been given to Guarantor previous to such demand of the acceptance by Noteholders
of this  Guaranty or of the creating or incurring of such  Obligations,  pay the
amount due thereon to Noteholders  as set forth in this  Guaranty,  and it shall
not be  necessary  for any  Noteholder,  in order to  enforce  such  payment  by
Guarantor,  first, to institute suit or exhaust its remedies against Borrower or
others liable on such Obligations, to have Borrower joined with Guarantor in any
suit brought under this Guaranty or to enforce their rights against any security
which shall ever have been given to secure such indebtedness; provided, however,
that in the event any Noteholder  elects to enforce and/or exercise any remedies
they may possess  with  respect to any  security  for the  Obligations  prior to
demanding  payment from  Guarantor,  Guarantor  shall  nevertheless be obligated
hereunder for any and all sums still owing to Noteholders on the Obligations and
not repaid or recovered incident to the exercise of such remedies.

                                       2
<PAGE>

     4.  Notice to  Guarantor  of the  acceptance  of this  Guaranty  and of the
making,  renewing or assignment of the  Obligations  and each item thereof,  are
hereby expressly waived by Guarantor.

     5. Each  payment  on the  Obligations  shall be deemed to have been made by
Borrower  unless  express  written notice is given to Noteholders at the time of
such payment that such payment is made by Guarantor as specified in such notice.

     6. If all or any part of the Obligations at any time are secured, Guarantor
agrees that Collateral Agent and/or Noteholders may at any time and from time to
time, at their  discretion  and with or without  valuable  consideration,  allow
substitution   or  withdrawal  of  collateral  or  other  security  and  release
collateral  or other  security or  compromise  or settle any amount due or owing
under the  Credit  Agreements  or amend or modify in whole or in part the Credit
Agreements or any Loan Paper executed in connection  with the Credit  Agreements
without  impairing  or  diminishing  the  obligations  of  Guarantor  hereunder.
Guarantor  further  agrees that if Borrower  executes in favor of any Noteholder
any collateral agreement, mortgage or other security instrument, the exercise by
any Noteholder of any right or remedy thereby conferred on such Noteholder shall
be wholly  discretionary with such Noteholder,  and that the exercise or failure
to  exercise  any such right or remedy  shall in no way impair or  diminish  the
obligation of Guarantor hereunder. Guarantor further agrees that Noteholders and
Collateral  Agent shall not be liable for their  failure to use diligence in the
collection  of the  Obligations  or in  preserving  the  liability of any Person
liable for the Obligations, and Guarantor hereby waives presentment for payment,
notice  of  nonpayment,   protest  and  notice  thereof   (including  notice  of
acceleration),  and diligence in bringing suits against any Person liable on the
Obligations,  or any part  thereof.  As used herein,  "Loan  Papers" shall mean,
collectively,  all Loan Papers,  as such term is defined in the Revolving Credit
Agreement,  and all Loan  Documents,  as such term is defined in the Term Credit
Agreement.

     7. Guarantor agrees that Noteholders,  in their  discretion,  may (a) bring
suit against all guarantors (including, without limitation, Guarantor hereunder)
of the Obligations jointly and severally or against any one or more of them, (b)
compound  or  settle  with  any  one  or  more  of  such   guarantors  for  such
consideration  as  Noteholders  may deem proper,  and (c) release one or more of
such guarantors from liability  hereunder,  and that no such action shall impair
the rights of  Noteholders  to collect the  Obligations  (or the unpaid  balance
thereof) from other such guarantors of the  Obligations,  or any of them, not so
sued,  settled  with  or  released.  Guarantor  agrees,  however,  that  nothing
contained in this paragraph,  and no action by Noteholders  permitted under this
paragraph,  shall in any way affect or impair the rights or  obligations of such
guarantors among themselves.

     8. Guarantor  represents and warrants to each Noteholder that (a) Guarantor
is a limited  liability  company duly  organized and validly  existing under the
laws of the State of Delaware;  (b) Guarantor  possesses all requisite authority
and power to  authorize,  execute,  deliver  and  comply  with the terms of this
Guaranty;  (c) this  Guaranty  has been  duly  authorized  and  approved  by all
necessary  action on the part of Guarantor  and  constitutes a valid and binding
obligation of Guarantor  enforceable in accordance with its terms, except as (1)
the enforcement thereof may be limited by applicable Debtor Relief Laws, and (2)
the availability of equitable remedies may be limited by equitable principles of
general applicability; and (d) no approval or

                                       3
<PAGE>

consent of any court or governmental  entity is required for the  authorization,
execution, delivery or compliance with this Guaranty which has not been obtained
(and copies thereof  delivered to  Noteholders).  As used in this Guaranty,  the
term "Debtor  Relief  Laws" means the  Bankruptcy  Code of the United  States of
America  and all  other  applicable  liquidation,  conservatorship,  bankruptcy,
moratorium, rearrangement,  receivership, insolvency, reorganization, suspension
of payments or similar debtor relief laws from time to time in effect  affecting
the rights of creditors generally.

     9. Guarantor  covenants and agrees that until the  Obligations are paid and
performed in full, it will (a) at all times maintain its existence and authority
to transact business in any state or jurisdiction where Guarantor has assets and
operations,  except  where the failure to maintain  such  existence or authority
would not have a Material  Adverse Effect,  (b) promptly  deliver to Noteholders
and to Collateral Agent such information respecting its business affairs, assets
and  liabilities  as  Noteholders  may  reasonably  request,  and (c)  duly  and
punctually  observe and perform all covenants  applicable to Guarantor under the
Credit Agreements and the other Loan Papers.  The failure of Guarantor to comply
with the terms of this paragraph  shall be an Event of Default under each Credit
Agreement.

     10. This Guaranty is for the benefit of Noteholders,  their  successors and
assigns,  and in the event of an assignment by Noteholders (or their  successors
or assigns) of the  Obligations,  or any part  thereof,  the rights and benefits
hereunder,  to the extent  applicable  to the  Obligations  so assigned,  may be
transferred with such  Obligations.  This Guaranty is binding upon Guarantor and
its successors and assigns.

     11. No modification,  consent, amendment or waiver of any provision of this
Guaranty,  nor  consent  to any  departure  by  Guarantor  therefrom,  shall  be
effective unless the same shall be in writing and signed by each Noteholder, and
then shall be effective  only in the  specific  instance and for the purpose for
which given.  No notice to or demand on Guarantor in any case shall,  of itself,
entitle  Guarantor to any other or further  notice or demand in similar or other
circumstances.  No delay or omission by  Noteholders  in exercising any power or
right hereunder shall impair any such right or power or be construed as a waiver
thereof or any acquiescence therein, nor shall any single or partial exercise of
any such power preclude other or further  exercise  thereof,  or the exercise of
any other  right or power  hereunder.  All rights and  remedies  of  Noteholders
hereunder are  cumulative of each other and of every other right or remedy which
Noteholders  may otherwise  have at law or in equity or under any other contract
or  document,  and the  exercise  of one or more  rights or  remedies  shall not
prejudice or impair the  concurrent  or  subsequent  exercise of other rights or
remedies.

     12. No provision herein or in any promissory note,  instrument or any other
Loan Paper executed by Borrower or Guarantor  evidencing the  Obligations  shall
require  the  payment  or permit the  collection  of  interest  in excess of the
Maximum  Lawful Rate.  If any excess of interest in such respect is provided for
herein or in any such promissory note, instrument,  or any other Loan Paper, the
provisions of this paragraph  shall govern,  and neither  Borrower nor Guarantor
shall be obligated  to pay the amount of such  interest to the extent that it is
in excess of the amount  permitted by law. The intention of the parties being to
conform strictly to any applicable federal or state usury laws now in force, all
promissory  notes,  instruments  and other Loan  Papers  executed by Borrower or
Guarantor evidencing the Obligations shall be held subject

                                       4
<PAGE>

to  reduction  to the amount  allowed  under said usury laws as now or hereafter
construed by the courts having jurisdiction.

     13. If  Guarantor  should  breach or fail to perform any  provision of this
Guaranty,  Guarantor agrees to pay Noteholders all costs and expenses (including
court  costs and  reasonable  attorneys  fees)  incurred by  Noteholders  in the
enforcement hereof.

     14. (a) The liability of Guarantor  under this Guaranty  shall in no manner
be impaired,  affected or released by the insolvency,  bankruptcy,  making of an
assignment for the benefit of creditors, arrangement,  compensation, composition
or readjustment of Borrower, or any proceedings affecting the status,  existence
or assets of  Borrower or other  similar  proceedings  instituted  by or against
Borrower and affecting the assets of Borrower.

         (b) Guarantor acknowledges and agrees  that any interest on any portion
of  the  Obligations  which  accrues  after  the  commencement of any proceeding
referred  to in clause (a) of this  Paragraph  14 above (or,  if interest on any
portion of the Obligations ceases to accrue by operation of law by reason of the
commencement  of said  proceeding,  such  interest as would have accrued on such
portion of the Obligations if said  proceedings had not been commenced) shall be
included in the Obligations because it is the intention of Guarantor, Collateral
Agent and  Noteholders  that the  Obligations  which are guaranteed by Guarantor
pursuant to this Guaranty should be determined without regard to any rule of law
or  order  which  may  relieve  Borrower  of any  portion  of such  Obligations.
Guarantor will permit any trustee in bankruptcy, receiver, debtor in possession,
assignee for the benefit of creditors or similar  Person to pay  Noteholders  or
Collateral  Agent,  or allow the claim of  Noteholders  or  Collateral  Agent in
respect of, any such interest  accruing after the date on which such  proceeding
is commenced.

         (c) In the event that all or any portion of the Obligations are paid by
Borrower,  the  obligations of Guarantor  hereunder shall continue and remain in
full  force and effect or be  reinstated,  as the case may be, in the event that
all or any part of such  payment(s)  are  rescinded  or  recovered  directly  or
indirectly from Collateral  Agent or any Noteholder as a preference,  fraudulent
transfer or otherwise, and any such payments which are so rescinded or recovered
shall constitute Obligations for all purposes under this Guaranty.

     15.  Guarantor  understands  and agrees  that any amounts of  Guarantor  on
account with any Noteholder may, after the occurrence and during the continuance
of an Event of  Default,  be offset to  satisfy  the  obligations  of  Guarantor
hereunder. Any Noteholder that offsets any such amounts against such obligations
shall take reasonable efforts to promptly notify Guarantor of such action.

     16.  Guarantor   hereby   subordinates  and  makes  inferior  any  and  all
indebtedness  now or at any time  hereafter owed by Borrower to Guarantor to the
Obligations  and agrees,  after the occurrence  and during the  continuance of a
Default  or an Event of Default  under and as  defined  in either the  Revolving
Credit Agreement or the Term Credit  Agreement,  or any event which with notice,
lapse of time, or both,  would constitute a Default or an Event of Default under
and as defined in either  the  Revolving  Credit  Agreement  or the Term  Credit
Agreement,  not to permit  Borrower to repay, or to accept payment from Borrower
of, such  indebtedness  or any part thereof without the prior written consent of
Noteholders.

                                       5
<PAGE>

     17. During the period that Revolving Lenders have any commitment to lend or
participate  in Letter of Credit  Exposure (as defined in the  Revolving  Credit
Agreement), or any amount payable under any Note remains unpaid or any Letter of
Credit (as defined in the Revolving Credit Agreement) remains  outstanding,  and
throughout any additional  preferential  period  subsequent  thereto,  Guarantor
shall not exercise any rights of subrogation to which Guarantor may otherwise be
entitled  against  Borrower,  or any other  guarantor of the  Obligations,  as a
result of any payment made by Guarantor pursuant to this Guaranty.

     18. As of the date  hereof,  the fair  saleable  value of the  property  of
Guarantor is greater than the total amount of liabilities  (including contingent
and unliquidated  liabilities) of Guarantor, and Guarantor is able to pay all of
its  liabilities  as  such  liabilities  mature  and  Guarantor  does  not  have
unreasonably  small capital  within the meaning of Section 548, Title 11, United
States Code,  as amended.  In computing  the amount of  contingent or liquidated
liabilities,  such  liabilities have been computed at the amount which, in light
of all the facts and  circumstances  existing as of the date hereof,  represents
the  amount  that can  reasonably  be  expected  to become an actual or  matured
liability.

     19. If any  provision  of this  Guaranty is held to be illegal,  invalid or
unenforceable,  under present or future Laws  effective  during the term hereof,
such provision  shall be fully  severable,  this Guaranty shall be construed and
enforced as if such  illegal,  invalid,  or  unenforceable  provision  had never
comprised a part hereof,  and the  remaining  provisions  hereof shall remain in
full force and effect and shall not be  affected  by the  illegal,  invalid,  or
unenforceable  provision or by its severance herefrom.  Furthermore,  in lieu of
such  illegal,   invalid,  or  unenforceable  provision  there  shall  be  added
automatically as a part of this Guaranty a provision as similar in terms to such
illegal,  invalid,  or unenforceable  provision as may be possible and be legal,
valid and enforceable.

     20. (a) Guarantor  hereby  irrevocably  submits to the  jurisdiction of any
Texas State or Federal court sitting in the Northern  District of Texas over any
action or  proceeding  arising out of or relating to this  Guaranty or any other
Loan Paper, and Guarantor hereby  irrevocably  agrees that all claims in respect
of such action or proceeding  may be heard and determined in such Texas State or
Federal  court.  Guarantor  agrees  that a final  judgment on any such action or
proceeding  shall be conclusive  and may be enforced in other  jurisdictions  by
suit on the judgment or in any other manner provided by Law.

         (b) Nothing in this  Paragraph 20 shall affect any right of Noteholders
to bring any action or proceeding  against any Guarantor or their  properties in
the courts of any other jurisdictions.

         (c) To  the  extent  that  Guarantor  has  or hereafter may acquire any
immunity  from  jurisdiction  of any  court or from any legal  process  (whether
through service or notice,  attachment  prior to judgment,  attachment in aid of
execution,  execution  or  otherwise)  with  respect to itself or its  property,
Guarantor hereby  irrevocably waives such immunity in respect of its obligations
under this Guaranty and the other Loan Papers.

     21. THIS  GUARANTY  AND THE OTHER LOAN PAPERS  COLLECTIVELY  REPRESENT  THE
FINAL AGREEMENT BY AND AMONG NOTEHOLDERS,

                                       6

COLLATERAL AGENT AND GUARANTOR AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS,  OR  SUBSEQUENT  ORAL  AGREEMENTS  OF  NOTEHOLDERS,  AGENT  AND
GUARANTOR. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG NOTEHOLDERS,  COLLATERAL
AGENT AND GUARANTOR.

     22. EACH NOTEHOLDER, BY ITS ACCEPTANCE OF THIS GUARANTY, AND GUARANTOR, FOR
ITSELF,  ITS  SUCCESSORS AND ASSIGNS,  HEREBY  IRREVOCABLY  AND  UNCONDITIONALLY
WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION
OR PROCEEDING  RELATING TO THIS GUARANTY OR ANY OF THE OTHER LOAN PAPERS AND ANY
COUNTERCLAIM THEREIN.

     23.  THIS  GUARANTY  AND THE  OTHER  LOAN  PAPERS  SHALL  BE  CONSTRUED  IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

     EXECUTED and effective as of the date first above written.

                   ARTICLE IV. REPRESENTATIONS AND WARRANTIES

     Section 4.01    Representations and Warranties with Respect to the Company.

     Each of the Quest  Subsidiaries,  jointly  and  severally,  represents  and
warrants to Investor that:

     (a)  Organization;  Qualification  and  Authority.  Each of the Company and
          Bluestem is a limited liability company duly formed, validly existing,
          and in good standing under the laws of the State of Delaware.  Each of
          the Company and Bluestem is duly  qualified to transact  business as a
          foreign limited  liability company and is in good standing in Oklahoma
          and Kansas,  and in each other  jurisdiction in which the character of
          its properties or the nature of its business makes such  qualification
          necessary,  other than those  jurisdictions  wherein the failure to so
          qualify would not have a material adverse effect. Subject to Customary
          Filings,  each of the Company and Bluestem has all power and authority
          to own,  lease and operate the properties  owned by it (including,  in
          the case of the  Company,  the  Devon  Assets,  the  Quest Oil and Gas
          Properties,  and  the  Other  Quest  Properties  and,  in the  case of
          Bluestem,  the Quest Gathering System),  and to carry on its business,
          as it is  now  being  conducted  and as it  will  be  conducted  after
          Closing.  The Company has all  requisite  power and authority to enter
          into  this  Agreement  and to  issue  the  Class A  Units  and has the
          requisite   power  and   authority  to  carry  out  the   transactions
          contemplated hereby to be performed by it, and the execution, delivery
          and  performance  hereof have been duly  authorized  by all  necessary
          action. This Agreement and each other agreement or instrument executed
          and delivered by the Company pursuant hereto or in connection herewith
          constitutes  the legal,  valid and binding  obligations of the Company
          and, except as may be affected by bankruptcy,  insolvency, moratorium,
          reorganization  and other laws and judicial  decisions  affecting  the
          rights of creditors  generally and general  principles of equity,  are
          enforceable  against the Company in accordance  with their  respective
          terms.  The Quest  Subsidiaries  have  delivered to Investor  true and
          correct  copies  of  the  LLC   Certificate,   LLC  Agreement,   Quest
          Contribution Agreement, and Quest Assignments.

     (b)  Capitalization of the Company. The outstanding membership interests of
          the Company  immediately  prior to Closing  consist of the  membership
          interests described on Schedule 4.01(b), each such membership interest
          being owned by the Person  indicated on Schedule  4.01(b).  Other than
          the membership  interests described on Schedule 4.01(b) and the rights
          of the members of the Company  expressed in the LLC  Agreement,  there
          are no  interests  of any kind  outstanding  that give any  Person the
          right to receive any benefit or right similar to the rights enjoyed or
          accruing to a holder of a membership interest in the Company or any

                                       9
<PAGE>

          rights to participate  in the  management  (other than pursuant to the
          Operating  and  Management  Agreement),  ownership  or earnings of the
          Company.  Upon  amendment  and  restatement  of the LLC  Agreement  at
          Closing,  the  membership  interests  of the Company  will  consist of
          10,000  Class B Units  issued to the  Persons  indicated  on  Schedule
          4.01(b),  and  10,000  Class A Units  authorized  and to be  issued to
          Investor at Closing. All Class A Units issued to the Investor pursuant
          to, and in accordance with the  requirements  of, this Agreement shall
          be  fully  paid  and  non-assessable  Class A  Units,  except  as such
          non-assessability  may be affected by section  18-607 of the  Delaware
          Limited Liability Company Act.

     (c)  Capitalization  of  Bluestem.  As of  Closing,  all of the  membership
          interests  of  Bluestem  are  owned  by the  Company.  Other  than the
          membership  interests owned by the Company,  there are no interests of
          any kind  outstanding  that give any Person  the right to receive  any
          benefit or right similar to the rights enjoyed or accruing to a holder
          of a membership  interest in Bluestem or any rights to  participate in
          the  management  (other than pursuant to the Operating and  Management
          Agreement), ownership or earnings of Bluestem.

     (d)  Defaults.  Neither  the  Company  nor  any  subsidiary  thereof  is in
          material  default under any indenture,  mortgage,  lease, or any other
          contract,   agreement  or  instrument  (provided,   however,  that  no
          representation  is made in this Section 4.01(d) as to the Contracts or
          Leases or the Devon Purchase and Sale Agreement, which are the subject
          of the Quest  Subsidiaries'  representations and warranties in Section
          4.04 and Section 4.05, respectively,  or the Devon Assets (as to which
          no representations or warranties are made herein)) or any order, writ,
          injunction  or  decree  of any  Governmental  Authority  to which  the
          Company or any subsidiary  thereof is a party or by which it or any of
          the Quest Assets are bound or affected, and there exists no condition,
          event or act which constitutes,  or which after notice, lapse of time,
          or both, would constitute, such a default under any of the foregoing.

     (e)  No  Violation.  The  execution  and delivery of this  Agreement by the
          Company  does  not,  and  the  consummation  by  the  Company  of  the
          agreements and  transactions  contemplated by this Agreement will not,
          (i) conflict with, or result in any violation of or default or loss of
          any benefit  under,  any provision of the LLC  Certificate  or the LLC
          Agreement,  as amended and  restated by the Amended and  Restated  LLC
          Agreement;  (ii) violate any Permit,  concession,  grant, law, rule or
          regulation,  or any judgment,  decree or order to which the Company or
          any  subsidiary  thereof  is a party or to which  the  Company  or any
          subsidiary  thereof or any of the Quest Assets are  subject;  or (iii)
          conflict  with,  or result in a breach or violation  of, or accelerate
          the  performance  required by, the terms of any  agreement,  contract,
          indenture or other  instrument  (excluding any of the Devon Assets) to
          which the Company or any subsidiary thereof is a party or to which any
          of the Quest  Assets are subject,  or  constitute a default or loss of
          any  right  thereunder  or an event  which,  with the lapse of time or
          notice or both,  is likely to result in a default or loss of any right
          thereunder or the creation of any Lien upon

                                       10
<PAGE>

          any of the Quest Assets,  excepting in the case of clause (iii) above,
          such conflicts, breaches, violations, accelerations,  defaults, losses
          or Liens as would not individually or in the aggregate have a material
          adverse effect.

     (f)  No Other Activities.  Except with respect to the Contributed Assets or
          as contemplated by this Agreement and the Related Agreements,  (i) the
          Company has not engaged in any business activity; and (ii) the Company
          has not incurred any material liabilities or obligations  (absolute or
          contingent).  The  Company  has no  assets  other  than  cash  and its
          equivalents,  100% of the  membership  interests of Bluestem,  and the
          Contributed Assets.

     (g)  Broker's  Fees.  The Company has incurred no liability for brokers' or
          finders'  fees  related  to  the  transactions  contemplated  by  this
          Agreement for which Investor shall be liable.  However, the Company is
          obligated to pay a fee to Energy Capital  Solutions in connection with
          this Agreement and the Related Agreements.

Section 4.02    Representations, and Warranties of Investor.

     Investor  represents and warrants to the Company and the Quest Subsidiaries
that:

     (a)  Organization;  Qualification  and  Authority.  Investor  is a  limited
          liability company duly formed,  validly existing, and in good standing
          under the laws of the State of Delaware. Investor is duly qualified to
          transact  business  and is in good  standing in each  jurisdiction  in
          which the  character of its  properties  or the nature of its business
          makes  such  qualification  necessary  and in which the  failure to so
          qualify would have a material  adverse effect.  Investor has the power
          to own its  properties and to carry on its business as it is now being
          conducted.  Investor has all  requisite  power and  authority to enter
          into this Agreement and has the requisite power and authority to carry
          out the  transactions  contemplated  hereby to be performed by it, and
          the  execution,   delivery  and  performance  hereof  have  been  duly
          authorized  by all  necessary  action.  No  approval of any members of
          Investor is required for consummation of the transactions contemplated
          by this Agreement or the Related  Agreements.  This Agreement and each
          other  agreement  or  instrument  executed  and  delivered by Investor
          pursuant hereto or in connection herewith constitutes the legal, valid
          and binding obligations of Investor, and, except as may be affected by
          bankruptcy, insolvency, moratorium,  reorganization and other laws and
          judicial  decisions  affecting  the rights of creditors  generally and
          general  principles of equity,  are  enforceable  against  Investor in
          accordance with their respective terms.

     (b)  No Conflicts.  The execution,  delivery and performance by Investor of
          this Agreement and the  consummation  by Investor of the  transactions
          contemplated  herein or in the Related Agreements will not (i) violate
          any provision of law,  statute,  rule, or regulation to which Investor
          is subject, (ii) violate any order,

                                       11
<PAGE>

          judgment, or decree applicable to Investor, or (iii) conflict with, or
          result in a breach or  default  under,  any term or  condition  of its
          certificate of limited  liability  company or other  organizational or
          governing  document  or any  agreement  or other  instrument  to which
          Investor is a party or by which Investor is bound.

     (c)  Investment Matters. Investor is an "accredited investor" as defined in
          Rule 501(a) under the  Securities  Act of 1933, as amended,  and it is
          acquiring  the Class A Units solely for its  beneficial  account,  for
          investment  purposes,  and  not  with a view  to,  or  for  resale  in
          connection   with,  any   distribution   in  violation  of  applicable
          securities laws.

     (d)  Broker's  Fees.  Investor has  incurred no  liability  for brokers' or
          finders'  fees  related  to  the  transactions  contemplated  by  this
          Agreement  for which the  Company or the Quest  Subsidiaries  shall be
          liable.

Section 4.03 General Representations and Warranties of the Quest Subsidiaries.

     Each Quest  Subsidiary,  jointly and severally,  represents and warrants to
Investor that:

     (a)  Organization;  Qualification and Authority. Each Quest Subsidiary is a
          corporation  or limited  liability  company,  as the case may be, duly
          formed,  validly existing,  and in good standing under the laws of the
          respective  state  of  formation  or  incorporation  indicated  in the
          preamble  above.  Each Quest  Subsidiary is duly qualified to transact
          business  as a foreign  corporation  and is in good  standing  in each
          jurisdiction in which the character of its properties or the nature of
          its  business  makes  such  qualification  necessary  and in which the
          failure to so qualify would have a material adverse effect. Each Quest
          Subsidiary  has the  power to own its  properties  and to carry on its
          business as it is now being  conducted.  Each Quest Subsidiary has all
          requisite power and authority to enter into this Agreement and has the
          requisite   power  and   authority  to  carry  out  the   transactions
          contemplated hereby to be performed by it, and the execution, delivery
          and  performance  hereof have been duly  authorized  by all  necessary
          action.  If the approval of any  stockholder  or  membership  interest
          owner of any Quest  Subsidiary or QRC is required in  connection  with
          the  contribution  of the  Contributed  Assets to the  Company  or the
          consummation of the transactions contemplated by this Agreement or the
          Related  Agreements,  such approval has been obtained.  This Agreement
          and each other  agreement or  instrument  executed and  delivered by a
          Quest Subsidiary pursuant hereto or in connection herewith constitutes
          the legal,  valid and  binding  obligations  of the  respective  Quest
          Subsidiary, and, except as may be affected by bankruptcy,  insolvency,
          moratorium,  reorganization  and  other  laws and  judicial  decisions
          affecting the rights of creditors  generally and general principles of
          equity,  are enforceable  against the respective  Quest  Subsidiary in
          accordance with their terms.

                                       12
<PAGE>

     (b)  No Conflicts.  The  execution,  delivery and  performance by the Quest
          Subsidiaries  of this  Agreement  and the  consummation  by the  Quest
          Subsidiaries of the transactions contemplated herein or in the Related
          Agreements  will  not,  without  the  giving of notice or the lapse of
          time,  or both,  (i) violate any provision of law,  statute,  rule, or
          regulation to which any Quest Subsidiary is subject,  (ii) violate any
          order,  judgment,  or decree  applicable to any Quest  Subsidiary,  or
          (iii) conflict with, or result in a breach or default under,  any term
          or condition of any of the Quest Subsidiaries' bylaws, certificates of
          incorporation,  or other  organizational  or governing  documents,  as
          applicable, or any material agreement or other instrument to which any
          Quest  Subsidiary  is a party or by which it is bound,  other than the
          failure to obtain  any  consent  to assign  required  under any of the
          Contracts or Leases.

     (c)  Broker's  Fees.  None  of the  Quest  Subsidiaries  has  incurred  any
          liability  for brokers' or finders'  fees related to the  transactions
          contemplated by this Agreement for which the Company or Investor shall
          be liable,  except for the fees owed by the Company to Energy  Capital
          Solutions.

Section 4.04    Representations and Warranties as to the Quest Assets.

     Each of the Quest  Subsidiaries,  jointly  and  severally,  represents  and
warrants to Investor the following with respect to the Quest Assets:

     (a)  Assignments  by  Quest  Subsidiaries.   The  Quest  Subsidiaries  have
          assigned, transferred and conveyed (i) to Bluestem the Quest Gathering
          System,  which, save and except for the Excluded Assets,  includes all
          of  Quest's  right,  title  and  interest  as of the date of the Quest
          Assignments  in and to  gathering  systems  and  pipelines  located in
          Allen, Chatauqua, Cowley, Elk, Greenwood, Labette, Montgomery, Neosho,
          Wilson, and Woodson Counties,  Kansas, and Craig, Nowata,  Rogers, and
          Washington   Counties,   Oklahoma,   together   with  all   contracts,
          rights-of-way,  easements, fixtures, equipment, improvements, Permits,
          records, and other real or personal property appertaining thereto; and
          (ii) to the Company the Quest Oil and Gas Properties,  which, save and
          except for the  Excluded  Assets and the assets  assigned to Bluestem,
          include all of Quest's right, title and interest as of the date of the
          Quest  Assignments  in and to oil and gas interests  located in Allen,
          Chatauqua,  Cowley,  Elk,  Greenwood,  Labette,  Montgomery,   Neosho,
          Wilson, and Woodson Counties,  Kansas, and Craig, Nowata,  Rogers, and
          Washington  Counties,  Oklahoma,  together with all wells,  contracts,
          rights-of-way,  easements, fixtures, equipment, improvements, Permits,
          records,  and other real or personal  property  appertaining  thereto.
          Subject  to the  Customary  Filings  and  the  rights  of  holders  of
          preferential rights and consents  identified in Schedule 4.04(v),  the
          Quest  Assignments  do not  conflict  with,  or  result in a breach or
          violation of, or accelerate the performance  required by, the terms of
          any  material  agreement  to which the Quest  Assets  are  subject  or
          constitute a material default  thereunder or an event which,  with the
          lapse of time

                                       13
<PAGE>

          or both, is likely to result in a material  default  thereunder or the
          creation  of any Lien  upon any of the  assets  or  properties  of the
          Company.

     (b)  Compliance  with Laws.  (i) The Quest Assets are in  compliance in all
          material respects with all applicable Laws relating to or bearing upon
          the ownership or operation of the Quest Assets; (ii) neither Quest nor
          the  Company  has  received  any  written  notice,  which has not been
          dismissed or otherwise  disposed of, that it has not so complied;  and
          (iii) with respect to the Quest Assets,  neither Quest nor the Company
          has been charged or threatened  with  Proceedings  with respect to any
          violation  of any  applicable  Law,  and to  the  Quest  Subsidiaries'
          knowledge,  none of Quest or the Company is under  investigation  with
          respect to any such violation.

     (c)  Environmental  Matters.  Neither  the present  condition  of the Quest
          Assets,  nor present or past  activities on the Quest Assets,  nor the
          manner of  operation  of the Quest  Assets  have  created  any present
          material violation of, or noncompliance with, an Environmental Law, or
          give rise to or create any material remediation or clean-up obligation
          or  liability  in  any  Person,  contingent  or  otherwise,  under  an
          Environmental Law. Without limiting the foregoing,  in connection with
          the use,  ownership or operation  of the Quest  Assets,  Quest has not
          directly or indirectly  caused a Release of any  Hazardous  Materials,
          except for Releases  that are not material or that have been  remedied
          in compliance with the Leases or applicable Environmental Laws (or are
          not  required  to  be   remediated)   and  which  have  no  continuing
          consequence to Company or the Quest Assets.  All internal and external
          environmental  audits,  studies and reports in the possession or under
          the  control of Quest  which are  relevant to the Company or the Quest
          Assets are  identified  on  Schedule  4.04(c).  Quest has  provided to
          Investor copies of each of such audits, studies and reports.

     (d)  Sufficiency of Contributed Assets. Except for the Excluded Assets that
          will be used by QES to operate the  Contributed  Properties  under the
          Operating  and  Management  Agreement and subject to obtaining all the
          consents  listed on Schedule  4.04(v),  Quest has  contributed  to the
          Company all of the equipment,  contracts,  Permits,  vehicles, plants,
          easements,  rights-of-way,  pipelines,  surface leases,  licenses, and
          other real or personal property necessary to own, operate and maintain
          the Quest Assets in accordance with Quest's past practices.

     (e)  Leases.  (i) The  Leases  are in full force and effect as to the lands
          described in Schedule  1.01(bb)  hereto;  (ii) neither  Company or its
          Quest  predecessor,  nor any other  party (to the Quest  Subsidiaries'
          knowledge),  is in breach  (or with  notice or the  passage of time or
          both may be in  breach) of any  obligation  under any of the Leases in
          any  material  respect  other  than due to the  failure  to obtain any
          consent listed on Schedule 4.04(v); and (iii) all royalties,  rentals,
          and other  payments  and  obligations  due under the Leases  have been
          timely paid or otherwise discharged in full on or before the due dates
          thereof.

                                       14

THIS PROVISION IS "CONSPICUOUS" FOR PURPOSES OF ALL STATE LAWS.

Section 5.05    Indemnification Procedures.

     (a)  Notice of Claims.  Investor shall give the Quest  Subsidiaries  prompt
          written notice of any claim for which  Investor seeks  indemnification
          hereunder,  setting forth the  particulars  associated  with the claim
          (including  a copy of the  written  claim,  if any) as then  known  by
          Investor.  The failure of Investor to give prompt notice of a claim as
          required by this section shall not relieve the Quest  Subsidiaries  of
          its obligations under this Agreement except to the extent such failure
          materially  prejudices  the  Quest  Subsidiaries'  ability  to  defend
          against the claim.

     (b)  Defense  of  Claims.   Within   thirty   (30)  days  after  the  Quest
          Subsidiaries   receive  a  claim  notice  from  Investor,   the  Quest
          Subsidiaries   shall  notify   Investor   whether  or  not  the  Quest
          Subsidiaries will assume responsibility for defense and payment of the
          claim.  Investor is  authorized,  prior to and during such thirty (30)
          day period, to file any motion, pleading or other answer that it deems
          necessary  or  appropriate  to  protect  its  interests  that  is  not
          prejudicial to the Quest Subsidiaries. If the Quest Subsidiaries elect
          not to assume  responsibility  for  defense  and payment of the claim,
          Investor may defend against, or enter into any settlement with respect
          to,  the claim as it deems  appropriate  without  relieving  the Quest
          Subsidiaries of any indemnification obligations the Quest Subsidiaries
          may have with respect to such claim. The Quest  Subsidiaries'  failure
          to respond in writing  to a claim  notice  within the thirty  (30) day
          period  shall be deemed an election by the Quest  Subsidiaries  not to
          assume  responsibility  for defense  and payment of the claim.  If the
          Quest  Subsidiaries  elect to assume  responsibility  for  defense and
          payment of the Claim: (a) the Quest Subsidiaries shall defend Investor
          against  the claim  with  counsel  of the Quest  Subsidiaries'  choice
          (reasonably acceptable to Investor), (b) Investor shall cooperate with
          the Quest Subsidiaries in all reasonable respects in such defense, (c)
          subject to the limitations in Section 5.03(a),  the Quest Subsidiaries
          shall pay any  judgment  entered or  settlement  with  respect to such
          claim,  and (d) the Quest  Subsidiaries  shall not consent to entry of
          any  judgment or enter into any  settlement  with respect to the claim
          that (i)  does not  include  a  provision  whereby  the  plaintiff  or
          claimant in the matter releases Investor from all

                                       22
<PAGE>

          liability  with respect to the claim or (ii)  contains  terms that may
          materially and adversely  affect  Investor  (other than as a result of
          money damages covered by the indemnity). In all instances Investor may
          employ  separate  counsel and  participate in defense of a claim,  but
          Investor  shall bear all fees and expenses of counsel  employed by the
          Investor.

ARTICLE VI.  MISCELLANEOUS

Section 6.01    Quest Assignments and Consents.

     (a)  Within two (2) Business Days after Closing,  the Company shall deliver
          to the appropriate  county clerks or other officers of the counties in
          which  the  Quest  Assets  are  located   counterparts  of  the  Quest
          Assignments  (together with applicable filing or recording fees) to be
          recorded  in the  appropriate  records of such  counties.  The Company
          shall furnish to Investor  copies of the recorded  counterparts of the
          Quest  Assignments.  In the event of errors or  omissions in the Quest
          Assignments,  the Company  and the Quest  Subsidiaries  will  execute,
          acknowledge  and deliver such  additional  assignments  or  correction
          instruments  and  take  such  further  action  as  may  be  reasonably
          necessary or desirable to correct such errors or omissions.

     (b)  After Closing, the Company and the Quest Subsidiaries shall diligently
          continue commercially reasonable efforts to obtain all of the consents
          and waivers of  preferential  rights  applicable  to the Quest  Assets
          which were not  obtained  prior to Closing.  The failure to obtain any
          such  consent  or  waiver  of  preferential  rights  shall be deemed a
          Defect,  as defined in the Amended and  Restated  LLC  Agreement,  and
          Investor shall be entitled to the remedies provided therein as to such
          Defect.

to require  performance of any provision of this Agreement  shall not affect its
right at a later time to enforce such  provision.  No waiver by any party of any
condition,  or of any  breach  of any  covenant,  agreement,  representation  or
warranty  contained in this Agreement,  in any one or more  instances,  shall be
deemed to be or construed as a further or
