                                       8


Price Payment shall be reduced by an amount equal to all NPI Payments that would
have been due and payable to the NPI Purchaser  through the Initial Closing Date
assuming that the  Conveyance  covering the Initial  Bundle had been made to the
NPI  Purchaser  effective  on the date of  commencement  of  production  of each
Accepted Well included in the Initial Bundle.

          (b)  The  amount  of the  Purchase  Price  Payment  agreed  to be paid
     pursuant to the applicable  Purchase  Supplement shall be billed to the NPI
     Purchaser by the Company as final AFE's for each Accepted Well are approved
     by the  Company on or before the 15th  calendar  day of each month (or,  if
     such day is not a Business  Day,  the next  succeeding  Business  Day) (the
     "Invoice  Date").  NPI Purchaser will make each payment of a Purchase Price
     Payment (or any portion thereof) within 5 Business Days of the Invoice Date
     by wire  transfer  of  immediately  available  funds to such banks and bank
     accounts  as  the  Company  shall  specify  in  the   applicable   Purchase
     Supplement.  As the Company  accrues  actual  Total Well  Construction  and
     Completion  Costs for an Accepted  Well,  the Company  will, on the Invoice
     Date following such accrual of actual costs, provide the NPI Purchaser of a
     reconciliation  of amounts  reflected in the AFE for each Accepted Well for
     which the NPI Purchaser has  previously  made a Purchase  Price Payment and
     the actual Total Well  Construction  and Completion Costs for such Accepted
     Well. To the extent that the actual Total Well  Construction and Completion
     Costs for an Accepted Well exceed the amounts reflected in the AFE, the NPI
     Purchaser  will,  subject to Section  2.5(c) pay its portion of the excess;
     and, to the extent that the actual Total Well  Construction  and Completion
     Costs for an Accepted Well are less than the amounts  reflected in the AFE,
     the Company will refund to the NPI Purchaser the amounts overpaid.  The NPI
     Purchaser and the Company agree that any such overpayments or underpayments
     will be reflected on the invoice  provided to the NPI Purchaser on the next
     succeeding Invoice Date that follows 90 days after first production from an
     Accepted Well by decreasing,  or  increasing,  the amount billed to the NPI
     Purchaser.  Not withstanding the preceding sentence, any of the Parties may
     elect in writing,  in lieu of offsetting any  overpayment  or  underpayment
     against amounts billed on the next Invoice Date, to have the Company refund
     any overpayments, or the NPI Purchaser to make any underpayments,  within 5
     Business  Days  of  the  Invoice  Date  on  which  such   overpayments   or
     underpayments are reflected by wire transfer of immediately available funds
     to such banks and bank accounts as the Company, or the NPI Purchaser, shall
     specify in the applicable Purchase Supplement or in such written request.

          (c) In addition to the  limitations  on the amount Red Oak is required
     to expend on any  Accepted  Bundle  pursuant to Section  4.3.1 of the JVEA,
     which limits shall also be deemed to limit the maximum  aggregate  Purchase
     Price  Payments (net of any NPI Payments as described in the JVEA) that NPI
     Purchaser  is required to make with  respect to any  Accepted  Bundle,  NPI
     Purchaser  shall  not be  obligated  to pay  Total  Well  Construction  and
     Completion  Costs  that  exceed  the  lesser  of (i) 130% of the  estimates
     reflected on the AFE's for an Accepted Well, or (ii) $3,500,000.00.  If the
     Total Well  Construction and Completion Costs for an Accepted Bundle exceed
     the  limits  specified  in  Section  4.3.1  of the JVEA or the  Total  Well
     Construction and Completion Costs for an Accepted Well exceed the estimates
     reflected  on the  respective  AFE by more  than  30% or are in  excess  of
     $3,500,000.00,  and NPI  Purchaser  elects not to fund any  portion of such


                                       9


     excess, then such event, NPI Purchaser's  aggregate Net Profits Interest in
     such  Accepted  Bundle or  Accepted  Well  shall be less than 25%,  and NPI
     Purchaser's  Percentage in that  Accepted Well or Accepted  Bundle shall be
     determined in accordance with Section 1.23 of the JVEA.

          (d) Under no circumstances shall NPI Purchaser be liable to Company or
     any  Third  Party  for  the  payment  of  any  portion  of the  Total  Well
     Construction  and  Completion  Costs.  It is the  agreement  of the Parties
     hereto  that  NPI  Purchaser  shall  (to  the  extent  otherwise  specified
     hereunder)  purchase  the Net  Profits  Interest by making  Purchase  Price
     Payments  in  amounts  which may be  determined,  among  other  things,  by
     reference  to  documented  and  verifiable  Total  Well   Construction  and
     Completion  Costs,  but that Company (and not NPI Purchaser) is responsible
     for paying all the Total Well Construction and Completion Costs.

          (e) The amount of all  Purchase  Price  Payments  paid to the  Company
     shall be reduced by 3.25% as provided in the  Engagement  Letter  ("Red Oak
     Payment").  The Red Oak  Payment  shall be paid by MBG and  MBGV  Partition
     directly to Red Oak by (i) wiring 2.25% of the  Purchaser  Price Payment to
     the account  specified by Red Oak at the time the Purchase Price Payment is
     paid to the Company,  and (ii) directing the Company to reduce MBG and MBGV
     Partition's  collective  25% Net  Profits  Interest to a 24.75% Net Profits
     Interest  and to convey,  pursuant  to the  Conveyance,  a .25% Net Profits
     Interest to Red Oak. For all other  purposes of this  Agreement,  including
     calculating the Net Profits Interest, the Red Oak Payment will be deemed to
     constitute part of the Purchase Price Payments. Red Oak will be entitled to
     the Conveyance of the Net Profits Interest specified in this Section 2.5(e)
     and the rights of an NPI  Purchaser  under  Sections  3.1, 3.2, and 6.1(a),
     (c), (d), (e), (g), (h), (i), and (k),  through (p) of this Agreement,  and
     subject to the  obligations  of an NPI Purchaser  under Section 3.3 of this
     Agreement,  but will not be  required  to pay any  portion of the  Purchase
     Price Payments or any other amounts pursuant to this Agreement and does not
     have any rights to terminate this  Agreement  pursuant to Article VII other
     than with respect to itself.


                             ARTICLE III - Payments

     3.1.  Payments to NPI Purchaser.  Company will pay any amounts owing to NPI
Purchaser under the Net Profits  Documents ("NPI  Payments") to NPI Purchaser by
wire transfer of immediately  available  funds to such banks and accounts as NPI
Purchaser  shall from time to time specify in writing at least five (5) Business
Days  prior to the  effective  date for any such  change  of  accounts.  The NPI
Payments  for each month  shall be paid to NPI  Purchaser  on or before the 28th
calendar day of the following  month, or if such day is not a Business Day, then
on the next Business Day  thereafter.  Pending receipt of any NPI Payment due to
NPI Purchaser, the same shall be held by the Company in trust for the benefit of
NPI Purchaser.

     3.2. Memorandum and Security Agreement. If the Company owns Equitable Title
to the Subject  Interests,  then upon the Initial  Closing,  and each Subsequent
Closing,  Company  shall  execute,  acknowledge  and  deliver a  Memorandum  and
Security  Agreement,  a form of which is attached as Exhibit C ("Memorandum  and


                                       10


Security   Agreement"),   describing  the  Subject  Interests  and  the  related
Production  Unit(s) to be included in the Conveyance and naming NPI Purchaser as
secured party covering a percentage of the Company's rights, titles and interest
in and to all personal property,  equipment and fixtures included in the Subject
Interests  that are  burdened  by, or are to be  burdened  by,  each Net Profits
Interest, in an amount equal to each NPI Purchaser's Net Profits Interest in the
Subject  Interests,  together with a percentage of the as-extracted oil, gas and
other  hydrocarbon  collateral  attributable  to the  Production  Units  for the
Accepted Wells equal to each NPI Purchaser's Net Profits Interest in the Subject
Interests. If Company owns record title to the Subject Interests,  then upon the
Initial Closing, and each Subsequent Closing, Company shall execute, acknowledge
and  deliver a  Security  Agreement,  a form of which is  attached  as Exhibit C
("Security  Agreement")  contemporaneous with the Conveyance.  Within 10 days of
the Company  acquiring  record title with respect to any Subject  Interests  for
which a Memorandum and Security  Agreement has been filed, the Company will file
a Conveyance  for such Subject  Interests  and any  necessary  amendments to the
Memorandum and Security Agreement reflecting the filing of the Conveyance.

     3.3  Reconveyance.  Within 10 days of an adjustment of NPI  Purchaser's Net
Profits  Interest  pursuant to Section  2.5(c),  NPI Purchaser  will execute and
deliver to Company a recordable  amendment to the  Conveyance or Memorandum  and
Security Agreement  reflecting the revised Net Profits Interest in such Accepted
Wells.  In  addition,  within 10 days of  termination  of this  Agreement by (i)
Company  pursuant to Section 7.1 or Section 7.2, or (ii) NPI Purchaser  pursuant
to Section 7.3, NPI  Purchaser  will execute and deliver a Conveyance or partial
termination  of Memorandum  and Security  Agreement with respect to all Accepted
Wells for which  drilling has not commenced  prior to such  termination  and for
which no portion of the Purchase  Price  Payments for such  Accepted  Wells have
been made. If (x) the Company  terminates this Agreement pursuant to Section 7.2
as a result of the NPI  Purchaser's  failure to pay any portion of the  Purchase
Price Payment for any Accepted Wells when due, or (y) NPI Purchaser fails to pay
any portion of the Purchase Price Payment for any Accepted Wells within ten (10)
Business  Days  after  such  Purchase  Price  Payment  becomes  due and  payable
following a termination of this Agreement,  then NPI  Purchaser's  aggregate Net
Profits  Interest  in such  Accepted  Wells  shall  be less  than  25%,  and NPI
Purchaser's  Percentage  in that Accepted Well shall be determined in accordance
with Section 1.23 of the JVEA. Within 10 days of determination of NPI Purchasers
Percentage  in any  Accepted  Wells  pursuant  to the  preceding  sentence,  NPI
Purchaser  will  execute and deliver to Company a  recordable  amendment  to the
Conveyance  or  Memorandum  and Security  Agreement  reflecting  the revised Net
Profits Interest in such Accepted Wells

                   ARTICLE V - Representations and Warranties

     5.1.  Representations and Warranties of Company.  Company hereby represents
and  warrants to NPI  Purchaser as of the date of this  Agreement  and as of the
Initial Closing Date and each Subsequent Closing Date that:

          (a) Company is a corporation duly  incorporated,  validly existing and
     in good standing under the laws of the state of its  incorporation and duly
     qualified to do business and in good standing as a foreign  corporation  in
     the State of Utah. Company has all requisite power and authority, corporate
     or  otherwise,  to own and  operate  its assets in Utah and to execute  and
     deliver,  and  perform  all of  its  obligations  under,  the  Net  Profits
     Documents. Company is not a "foreign person" within the meaning of Sections
     1445 and 7701 of the Internal  Revenue Code, as amended  (i.e.,  Company is
     not a non resident alien, foreign corporation, foreign partnership, foreign
     trust or foreign estate as those terms are defined in the Internal  Revenue
     Code and any regulations promulgated thereunder).

          (b) The  execution,  delivery  and  performance  by Company of the Net
     Profits  Documents,  and the consummation of the transactions  contemplated
     herein and in the other Net Profits Documents, have been duly authorized by
     all  necessary  corporate  action and do not and will not (i)  violate  any
     material provision of any law, rule,  regulation,  order,  writ,  judgment,
     decree,  determination or award presently in effect having applicability to
     Company or of the  Certificate of  Incorporation,  By-laws or other charter
     documents  of  Company,  or (ii)  result in a breach  of, or  constitute  a
     default under, any material contract,  indenture,  instrument, or agreement
     to which Company is a party or by which it or its property may be presently
     bound or  affected  (including  the leases  under which  Company  holds the
     interests in the Subject  Interests),  or result in or require the creation
     or imposition of any lien or encumbrance on any assets of Company.  Company
     has obtained or has caused to be obtained all consents,  authorizations and
     waivers necessary under any such material contract,  indenture,  instrument
     or agreement or under any such material provision of law, rule, regulation,
     order, writ,  judgment,  decree,  determination or award in order to permit
     the valid execution, delivery and performance by Company of the Net Profits
     Documents.

          (c) The Net Profits Documents have been duly executed and delivered by
     Company and constitute the legal, valid and binding acts and obligations of
     Company,  enforceable  against  Company in accordance  with the  respective


                                       15


     terms of such Net  Profits  Documents,  except as such  enforcement  may be
     limited  by  bankruptcy,  insolvency,  moratorium  and other  similar  laws
     applicable  to  creditors'  rights  generally or by general  principles  of
     equity.

          (d) As of the date of this  Agreement,  there is no  suit,  action  or
     other  proceeding  pending for which  Company is a party or, to the best of
     Company's  knowledge  threatened,  before any court or  governmental  body,
     authority  or agency  which  relates to the  Contract  Area or to Company's
     ability to consummate the transactions contemplated by this Agreement.

          (e)  Except as could not  reasonably  be  expected  to have a material
     adverse  effect,  Company  possesses  all  licenses,   permits,  variances,
     exemptions,  consents,  certificates,  orders, approvals and authorizations
     necessary to own its  interests in the Contract  Area,  and to carry on its
     business as now being conducted  including,  but not limited to,  drilling,
     equipping, completing and operating Accepted Wells (other than such permits
     which customarily are not obtained until a drillsite has been identified or
     until an operator is ready to commence drilling operations;  provided, that
     Company will possess all such  permits as and when  required by  applicable
     law).

          (f)  Company  is in  compliance  with  all  laws,  ordinances,  rules,
     regulations,   judgments,   decrees  and  orders   (collectively,   "Laws")
     applicable   to  the  Contract   Area,   except  to  the  extent  that  any
     non-compliance  is not reasonably  expected to result in a material adverse
     effect on Company's  interests  or any  Accepted  Wells and Company has not
     received  any  notice  of  any  claimed  noncompliance  therewith.  To  the
     knowledge of Company,  there are no facts,  conditions or  circumstances in
     connection  with,  related to or associated  with  Company's  interests and
     Accepted Wells that could  reasonably be expected to give rise to any claim
     or assertion that Company,  any leases or the ownership or operation of any
     Accepted Wells is not in material compliance with any applicable Law.

          (g)  To  the  best  of  Company's  knowledge  the  data,  information,
     exhibits, memoranda and reports furnished by or on behalf of Company to NPI
     Purchaser in connection with the  negotiation of the Net Profits  Documents
     (taken as a whole,  and taking into account all corrections and supplements
     to such  information  heretofore  delivered)  are true and  correct  in all
     material  respects  and  no  statement  of  the  Company  contained  in any
     document, certificate, or other writing furnished or to be furnished by the
     Company pursuant hereto contains or will contain,  at the time of delivery,
     any untrue  statement of a material fact or omits, or will omit at the time
     of delivery,  to state any fact  necessary in order to make the  statements
     contained therein, in light of the circumstances under which they are made,
     not misleading. The Company knows of no matter which has not been disclosed
     to the NPI Purchaser pursuant to this Agreement, which has or is reasonably
     likely  to have a  material  adverse  effect  on the  ownership  of the Net
     Profits  Interest.  Except for effects  relating to the economy in general,
     changes in hydrocarbon  prices,  or other changes affecting the hydrocarbon
     industry generally, or for oil and gas production from the Contract Area in
     the ordinary  course of business or for matters  disclosed to NPI Purchaser
     in writing,  no material adverse change in the condition or aggregate value


                                       16


     of Company's  interest in the Contract Area has occurred  since the date of
     the last reserve  engineering  report delivered by Company to NPI Purchaser
     with respect to the Contract Area.

          (h) Company will be the owner (or have appropriate  operational rights
     under a farmout  or  earning  agreement  with the  owner) of the  leasehold
     interests  constituting the Production Unit of each Accepted Well, but only
     to the extent indicated in the drilling opinion furnished by Company to NPI
     Purchaser with the AFE for the Accepted Well.

     5.2.  Representations  and Warranties of NPI Purchaser.  MBG, MBG Partition
and Red Oak hereby represent and warrant to Company severally,  and not jointly,
as of the date of this Agreement that:

          (a) Such NPI Purchaser is a Delaware  limited  liability  company duly
     formed,  validly  existing and in good standing under the laws of the state
     of its formation and duly  qualified to do business and in good standing as
     a foreign entity in the State of Utah.

          (b) The execution,  delivery and  performance by such NPI Purchaser of
     the  Net  Profits  Documents,  and  the  consummation  of the  transactions
     contemplated herein and in the other Net Profits Documents,  have been duly
     authorized by all necessary corporate or similar action and do not and will
     not (i) violate any material provision of any law, rule, regulation, order,
     writ, judgment,  decree,  determination or award presently in effect having
     applicability  to such  NPI  Purchaser  or of the  formation  or  governing
     documents  of such  NPI  Purchaser,  or (ii)  result  in a  breach  of,  or
     constitute a default under, any material contract,  indenture,  instrument,
     or agreement  to which such NPI  Purchaser is a party or by which it or its
     property may be presently bound or affected.

          (c) The Net Profits Documents have been duly executed and delivered by
     such NPI Purchaser  and  constitute  the legal,  valid and binding acts and
     obligations of such NPI Purchaser,  enforceable  against such NPI Purchaser
     in  accordance  with the  respective  terms of such Net Profits  Documents,
     except  as such  enforcement  may be  limited  by  bankruptcy,  insolvency,
     moratorium and other similar laws applicable to creditors' rights generally
     or by general principles of equity.

          (d) Such NPI Purchaser is purchasing the Net Profits  Interest for its
     own account and not with a view to resale and has such knowledge, skill and
     experience  in  business,  financial  and oil and gas matters so that it is
     capable of evaluating the risks of entering into the Net Profits  Documents
     and the transactions contemplated herein. To the extent necessary, such NPI
     Purchaser has  retained,  at its own expense,  and relied upon  appropriate
     professional  advice  regarding  the  investment,  tax and legal merits and
     consequences of the Net Profits Documents and the transactions contemplated
     herein.

          (e) Such NPI  Purchaser  is an  "accredited  investor"  as  defined in
     Regulation D under the Securities Act of 1933, as amended.

                                       17


                             ARTICLE VI - Covenants

     6.1. Covenants of Company. Company covenants and agrees that until the full
and final  payment of all  payments due to NPI  Purchaser  under the Net Profits
Documents and the  termination of this  Agreement and the Net Profits  Interest,
unless NPI Purchaser has previously agreed otherwise:

          (a) Company will perform all of its covenants and duties under the Net
     Profits Documents all as fully as if they were set out in full herein.

          (b) In addition to any reports and information  specifically  required
     by the terms of this Agreement or the Conveyance, Company agrees to furnish
     to NPI Purchaser  full  information,  at all  reasonable  times,  which NPI
     Purchaser may request  concerning  any covenant,  provision or condition of
     the Net Profits  Documents or any matter or records in connection with such
     documents or, subject to  confidentiality  undertakings with Third Parties,
     with the  operation  of,  reserve  engineering  for,  production  from,  or
     accounting  for the  Subject  Interests.  Subject  to any  restrictions  on
     Company's right to do so under applicable  operating  agreements or similar
     contracts, Company will permit representatives designated by NPI Purchaser,
     including independent accountants, agents, attorneys, and other Persons, to
     visit and inspect the Subject  Interests  and  Company's  books and records
     pertaining  to the Subject  Interests  (and to make copies and  photocopies
     from such  records  and to write down and record such  information  as such
     representatives  may  request,  provided  that  no  copies  may be  made of
     geological or seismic data), and Company shall permit NPI Purchaser and its
     designated   representatives  reasonably  to  investigate  and  verify  the
     accuracy  of  information  furnished  to  NPI  Purchaser  hereunder  or  in
     connection  herewith  and to discuss all such  matters  with its  officers,
     employees and representatives.

          (c) If any Person  ever  challenges  or attacks  (i) the  validity  or
     priority of any Net Profits Document or of any rights, titles, or interests
     created or evidenced thereby or (ii) the title of Company to any portion of
     the  Subject  Interests  or of NPI  Purchaser  to any part of a Net Profits
     Interest  ("Title  Claim"),  then upon learning  thereof  Company will give
     prompt  written  notice  thereof to NPI Purchaser and at Company's own cost
     and expense will defend the NPI Purchaser and diligently endeavor to defeat
     such  challenge  or attack and to cure any defect that may be  developed or
     claimed,  and  Company  will take all  necessary  and proper  steps for the
     defense  of any legal  proceedings  with  respect  thereto,  including  the
     employment  of counsel (at  reasonable  fees) to represent  Company and NPI
     Purchaser,  the  prosecution or defense of  litigation,  and the release or
     discharge  of all adverse  claims.  The Company  shall not settle any Title
     Claim in a manner that would in any way affect the  validity or priority of
     any Net Profits Document or of any of NPI Purchaser's  rights,  titles,  or
     interests  created or  evidenced  thereby or NPI  Purchaser's  Net  Profits
     Interest without the prior written consent of the NPI Purchaser. Unless the
     Company  notifies  the NPI  Purchaser,  (whether or not named as a party to
     legal proceedings with respect  thereto),  in writing within 30 days of the
     Company  learning  of a Title  Claim  that  the  Company  will  defend  NPI
     Purchaser  against  any such  Title  Claim,  then NPI  Purchaser  is hereby
     authorized  and  empowered  to  take  such  steps  as in its  judgment  and


                                       18


     discretion  may be  necessary  or proper for the  defense of any such legal
     proceedings  or the  protection  of the  validity  or  priority  of the Net
     Profits  Documents  and  the  rights,  titles,  and  interests  created  or
     evidenced thereby,  including the employment of one independent  counsel at
     reasonable fees to represent all of the NPI Purchasers,  the prosecution or
     defense of  litigation,  the  compromise or discharge of any adverse claims
     made with respect to a Net Profits Interest,  the purchase of any tax title
     and the removal of prior liens or security interests,  and all expenditures
     so made of every kind and character  shall be reimbursed by Company  (which
     obligation  Company  hereby  expressly  promises to pay on demand) owing by
     Company to NPI  Purchaser  and shall bear  interest  from the date demanded
     until paid at the Agreed  Rate.  After  notice  from the Company to the NPI
     Purchaser of its assumption of the defense of such Title Claim, the Company
     shall not be liable to the NPI Purchaser  under this Section 6.1(c) for any
     legal  expenses  subsequently  incurred by the NPI  Purchaser in connection
     with the defense thereof,  except for such expenses  incurred in connection
     with  cooperation  with,  or at the  request  of,  the  Company;  provided,
     however,  that the NPI Purchaser shall have the right to employ one counsel
     to  represent  all  of the  NPI  Purchasers  if,  in  the  NPI  Purchaser's
     reasonable judgment,  based upon the advice of counsel, it is advisable, in
     light of the separate  interests of the NPI Purchaser and the Company,  for
     the NPI Purchaser to be represented by separate counsel,  and in that event
     the reasonable fees and expenses of such separate  counsel shall be paid by
     the Company.

          (d) Company will, on request of NPI  Purchaser,  (i) promptly  correct
     any defect,  error or omission  which may be  discovered  in the  contents,
     execution or  acknowledgment  of any Net Profits  Document that  materially
     affects or that may materially affect NPI Purchaser's right to purchase Net
     Profits  Interests in the Offered Bundles  pursuant to this Agreement,  its
     title to the Net Profits  Interest  or its right to receive  NPI  Payments;
     (ii)  execute,  acknowledge,  deliver  and  record  or  file  such  further
     instruments  and do such  further  acts as may be  necessary,  desirable or
     proper  for the  specific  and  exclusive  purpose  of  providing  a proper
     conveyance of the Net Profits  Interest to carry out more  effectively  the
     purposes of the Net Profits  Documents and to more fully  identify and make
     subject to the  Conveyance  any  property  intended to be covered  thereby,
     including  any  renewals,   additions,   substitutions,   replacements,  or
     appurtenances  to the Subject  Interests;  and (iii) execute,  acknowledge,
     deliver, and file or record any document or instrument reasonably requested
     by NPI Purchaser to protect its rights,  title and interests  under the Net
     Profits  Documents  against  the rights or  interests  of any Third  Party.
     Company shall pay all reasonable costs connected with any of the foregoing.

          (e)  Company  will not  cause or permit  any  portion  of the  Subject
     Interests or Company to be in material  violation of any Environmental Laws
     or do anything or permit  anything to be done which will subject Company or
     any portion of the Subject Interests to any material  remedial  obligations
     under any  Environmental  Laws,  assuming  in each case  disclosure  to the
     applicable  governmental  authorities of all relevant facts, conditions and
     circumstances, and Company will promptly notify NPI Purchaser in writing of
     any  existing,  pending or, to the best  knowledge  of Company,  threatened
     investigation or inquiry by any private party or governmental  authority in


                                       19


     connection  with any  Environmental  Laws.  Company  will  take  all  steps
     necessary to  determine  that no  Hazardous  Substances  are disposed of or
     otherwise  released  or being  released on or to any portion of the Subject
     Interests in violation of any Environmental Laws. Company will not cause or
     permit the disposal or other  release of any  Hazardous  Substance on or to
     the Subject  Interests in violation of any  Environmental Law and covenants
     and agrees to remove or remediate  any  Hazardous  Substance on the Subject
     Interests.  NPI Purchaser has no  responsibility  for  compliance  with any
     Environmental  Laws and the Company shall  indemnify the NPI Purchaser from
     any and all liabilities,  costs,  expenses (including,  without limitation,
     litigation  costs and attorney  fees),  damages,  or liens  incurred by NPI
     Purchaser with respect to any demands,  judgments, suits, causes of action,
     and claims of any kind or  character  arising or to arise from the presence
     of any adverse environmental condition or damage located on or attributable
     to the Subject Interests.

          (f) Prior to commencement of drilling operations on any Accepted Well,
     Company will obtain a drilling title opinion or, in the case of a drillsite
     which is on lands held by  production,  conduct such other title review and
     related  due  diligence  acceptable  to  NPI  Purchaser  and  as  would  be
     consistent  with sound oil and gas field  practices  for the  location  and
     nature of such  drillsite and related  Accepted Well  demonstrating  to the
     reasonable  satisfaction  of NPI  Purchaser  that (i)  Company has Good and
     Defensible  Title to the Subject  Interests and that (ii) the NPI Purchaser
     owns or will own the Net  Profits  Interest,  free and clear of all  liens,
     security  interests,   pledges,   collateral   assignments,   charges,  and
     encumbrances,  and (iii) the Conveyance, or, if Company owns only Equitable
     Title to the Subject  Interests to be burdened by the Net Profits Interest,
     then a Memorandum  and Security  Agreement,  has been duly  recorded in the
     real property records of the appropriate jurisdiction(s). If the Conveyance
     or the Memorandum and Security Agreement has not been filed at the time the
     opinion contemplated by the preceding sentence is provided,  the opinion in
     clause (iii) of the preceding sentence does not need to be provided on such
     date; provided,  however,  that NPI Purchaser may require Company to update
     any specified title opinions, including the addition of clause (iii) of the
     proceeding  sentence,  through  the  recording  of  the  Conveyance  or the
     Memorandum  and  Security  Agreement  or to  otherwise  provide  assurances
     reasonably  acceptable to NPI Purchaser that the NPI Purchaser owns its Net
     Profits  Interest  of  record,  free  and  clear  of  all  liens,  security
     interests, pledges, collateral assignments,  charges, and encumbrances, (it
     being understood that no title deficiencies  learned of by NPI Purchaser at
     any time shall in any way be deemed to qualify any of Company's  warranties
     of title or  indemnities  with  respect to title in any of the Net  Profits
     Documents).

          (g)  Company  will at all times  obtain  and  possess  (or cause to be
     obtained and possessed) all consents,  authorizations and waivers necessary
     under any material contract, indenture,  instrument or agreement binding on
     or  affecting  Company  or any of  Company's  assets or under any  material
     provision  of  law,  rule,  regulation,   order,  writ,  judgment,  decree,
     determination or award binding on or affecting  Company or any of Company's
     assets,  in order to permit the  performance  by Company of the Net Profits
     Documents.

                                       20


          (h) Company will  maintain  Good and  Defensible  Title to the Subject
     Interests  and the Accepted  Wells,  free and clear of all liens,  security
     interests, and encumbrances except for Permitted Encumbrances, subject only
     to Net Profits Interests and to other net profits interests contemplated by
     the JVEA.

          (i) Company shall maintain, or cause to be maintained, during the life
     of the Net  Profits  Interest,  insurance  coverage in such  amounts,  with
     provisions  for  such  deductible  amounts,  and for such  purposes  as are
     consistent  with prudent  operating  standards and the  requirements of any
     joint operating  agreement  applicable to the concerned Subject  Interests.
     Notwithstanding  the  foregoing,  the Company  shall  maintain  the minimum
     insurance coverages specified in Schedule 6.1(i).

               (j)  Company  will use its best  efforts  to cause  the  Oilfield
          Services  Parties to provide  services  with respect to each  Accepted
          Well in  accordance  with the terms of the JVEA and related  documents
          and each other person or entity providing services with respect to any
          Accepted  Well to provide  such  services  at the best price and terms
          available,  and in any event, at rates consistent with each provider's
          then  current  bidding  practices  and contract  rates with  similarly
          situated operators for similar equipment and services in the area.

               (k) All Accepted  Wells in which Company does not own 100% of the
          working  interest  will be operated by Company  pursuant to  customary
          joint  operating  agreements.  Company  will  conduct and carry on the
          exploration,  development,  maintenance  and operation of the Accepted
          Wells with reasonable and prudent business  judgment and in accordance
          with sound oil and gas field practices.

               (l) Except (i) to safeguard life or property, (ii) to maintain or
          repair,  (iii)  for  operations  to  restore  or  enhance  Hydrocarbon
          Production  from an  Accepted  Well,  or (iv) in the  event  of  force
          majeure or as required by  government  action,  Company shall not shut
          in,  temporarily  abandon  or abandon  any  Accepted  Well  capable of
          producing  Hydrocarbon  Production and equipped to so produce,  nor in
          any way  intentionally  reduce the  production  from any Accepted Well
          below  its  capability  without  the  prior  written  approval  of NPI
          Purchaser.

               (m) All  gas  produced  from  any  Accepted  Well  shall  be sold
          pursuant to gas sales  agreements  that are comparable  with other gas
          sales  agreements  in the Contract  Area;  provided,  that in the case
          sales of any  production  from any Accepted  Well to Company or any of
          its  Affiliates,  such  purchase  shall be on terms  comparable  to or
          better than those received by Company from non-Affiliates for purchase
          of production from the Contract Area or on terms comparable with other
          contemporaneous  non-affiliated purchases in the same general area. If
          any gathering, transportation,  compression or processing charges used
          in the calculation of the Production  Costs (as defined and calculated
          in the JVEA) includes  payments to  Affiliates,  such payment shall be
          comparable to or lower than payments made by Company to non-Affiliates
          for  similar  services  or  shall  be  comparable  to  or  lower  than
          contemporaneous  payments made by other  operators in the same general
          area for similar services.

                                       21


               (n)  Company  will not  enter  into any  transaction,  including,
          without limitation, any purchase, sale, lease or exchange of property,
          the  rendering  of any  service  or  the  payment  of any  management,
          advisory  or  similar  fees,  with any  Affiliate  with  regard to the
          Subject  Interests  unless  (i) such  transaction  is  evidenced  by a
          written  agreement  between  the  parties,  (ii) such  transaction  is
          otherwise  permitted  under  this  Agreement,  (iii) the terms of such
          transaction are comparable to and  competitive  with that of unrelated
          Third  Parties  rendering  comparable  services  or selling or leasing
          equipment  or  supplies  in the  same  geographical  area,  (iv)  such
          transaction involves payment only for services,  equipment or supplies
          reasonably  necessary  for the  prudent  operation  of,  and  actually
          furnished with respect to, the Subject  Interests,  and (v) except for
          the gas sales agreements  contemplated by Section 6.1(m), in the event
          the aggregate fair market value of the consideration  paid or received
          in any such  transactions  exceeds  $50,000,  NPI Purchaser shall have
          approved of such  transaction in writing after full  disclosure of all
          of the material terms thereof.

               (o) Except for Permitted Encumbrances,  Company will not, without
          the prior written  consent of NPI Purchaser,  encumber,  mortgage,  or
          make any disposition of its interest in the Subject  Interests  except
          for such  encumbrances as are expressly  subject to this Agreement and
          the other Net Profits Documents, or the JVEA.

               (p)  Company  will  promptly  notify NPI  Purchaser  of any suit,
          action, claim,  proceeding or investigation,  commenced or threatened,
          relating  to, or which may  affect,  the  Subject  Interests,  Project
          Wells,  any Net  Profits  Document  or the  Company's  interest in any
          Accepted Wells.

               (q) Upon  request,  Company  shall,  subject to their  reasonable
          availability and the limitations of confidentiality  undertakings with
          co-owners  or other  Third  Parties,  furnish  NPI  Purchaser  and its
          respective duly authorized agents and  representatives,  including its
          advisers and consultants, copies of all electric and other logs of the
          Accepted  Wells.  In addition and subject to the same  confidentiality
          limitations, NPI Purchaser and its advisers and consultants shall also
          have access to all records  regarding  all  seismic  data  (subject to
          limitations of  confidentiality  undertakings  with co-owners or Third
          Parties),  cores, cuttings, and other geological,  well and production
          data secured from operations on the Subject Interests.

               (r)  Company  will  furnish  or  cause  to be  furnished  to  NPI
          Purchaser the following reserve reports:

                           (i) Promptly after December 31 of each calendar year
                  (commencing with the calendar year 2004), and in any event not
                  later than March 31 of the next succeeding calendar year, a
                  reserve report, prepared by the Approved Independent Engineer

                          ARTICLE VIII - Miscellaneous

         8.1. Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by Company or NPI Purchaser in exercising any right, power
or remedy which Company or NPI Purchaser may have under any of the Net Profits
Documents shall operate as a waiver thereof or of any other right, power or
remedy, nor shall any single or partial exercise by Company or NPI Purchaser of
any such right, power or remedy preclude any other or further exercise thereof
or of any other right, power or remedy. No waiver of any provision of any Net
Profits Document and no consent to any departure therefrom shall ever be
effective unless it is in writing and signed by NPI Purchaser and Company, and
then such waiver or consent shall be effective only in the specific instances
and for the purposes for which given and to the extent specified in such
writing. No notice to or demand on NPI Purchaser or Company shall in any case of


                                       24


itself entitle NPI Purchaser or Company to any other or further notice or demand
in similar or other circumstances. This Agreement and the other Net Profits
Documents set forth the entire understanding and agreement of the Parties hereto
and thereto with respect to the transactions contemplated herein and therein and
supersede all prior discussions and understandings with respect to the subject
matter hereof and thereof, and no modification or amendment of or supplement to
this Agreement or the other Net Profits Documents shall be valid or effective
unless the same is in writing and signed by the party against whom it is sought
to be enforced. To the extent of any conflict between the terms of this
Agreement and the JVEA, the terms of this Agreement shall govern to the extent
of such conflict.

         THIS WRITTEN AGREEMENT AND THE OTHER NET PROFITS DOCUMENTS REPRESENT
THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE
OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         8.2. Survival of Agreements; Cumulative Nature. All of the various
representations, warranties, indemnities, covenants and agreements in the Net
Profits Documents shall survive the execution and delivery of this Agreement and
the other Net Profits Documents and the performance hereof and thereof,
including the granting of the Net Profits Interest and the delivery of the
Conveyance. The representations, warranties, indemnities, and covenants made by
the parties in the Net Profits Documents, and the rights, powers, and privileges
granted to the parties in the Net Profits Documents, are cumulative, and, except
for expressly specified waivers and consents, no Net Profits Document shall be
construed in the context of another to diminish, nullify, or otherwise reduce
the benefit to either party of any such representation, warranty, indemnity,
covenant, right, power or privilege. In particular and without limitation, no
exception set out in this Agreement to any representation, warranty, indemnity,
or covenant herein contained shall apply to any similar representation,
warranty, indemnity, or covenant contained in any other Net Profits Document,
and each such similar representation, warranty, indemnity, or covenant shall be
subject only to those exceptions which are expressly made applicable to it by
the terms of the various Net Profits Documents.

         8.3. Notices. All notices, requests, consents, demands and other
communications (in this section, collectively called "notices") which are
required or permitted under any Net Profits Document shall be in writing, unless
otherwise specifically provided in such Net Profits Document, and shall be
deemed sufficiently given or furnished if delivered by personal delivery, by
telecopy, by delivery service with proof of delivery, or by registered or
certified United States mail, postage prepaid, to Company or NPI Purchaser at
its address specified on the signature pages hereto. Any such notice shall be
deemed to have been given (a) in the case of personal delivery or delivery
service, as of the date of first attempted delivery at the address and in the
manner provided herein, (b) in the case of telecopy, upon receipt, or (c) in the
case of registered or certified United States mail, three days after deposit in
the mail. Company and NPI Purchaser may change its address from time to time by
sending a notice of the new address, in the manner provided for in this section,
to the other parties hereto.

                                       25


         8.4. Parties in Interest. All grants, covenants and agreements
contained in the Net Profits Documents shall bind and inure to the benefit of
the parties thereto and their respective successors and assigns.

         8.5. Governing Law. Except to the extent that the law of another
jurisdiction may be expressly elected in a Net Profits Document or the real
property laws of the state in which the Subject Interests are mandatorily
applicable, the Net Profits Documents shall be deemed contracts and instruments
made under the laws of the State of Colorado and shall be construed and enforced
in accordance with and governed by the laws of the State of Colorado and the
laws of the United States of America, without regard to principles of conflicts
of law.

         8.6. Limitation on Interest. Although the Net Profits Documents provide
for the sale and purchase of a real property interest and not a loan, there are
certain provisions of the Net Profits Documents which provide for the charging
and payment of interest. NPI Purchaser and Company intend to contract in strict
compliance with applicable usury law from time to time in effect. In furtherance
thereof they hereby stipulate and agree that none of the terms and provisions
contained in the Net Profits Documents shall ever be construed to create a
contract to pay, for the use, forbearance or detention of money, interest in
excess of the maximum amount of interest permitted to be charged by applicable
law from time to time in effect. No party to any Net Profits Document shall ever
be liable for unearned interest or shall ever be required to pay interest in
excess of the maximum amount that may be lawfully charged under applicable law
from time to time in effect, and the provisions of this section shall control
over all other provisions of the Net Profits Documents which may be in conflict
or apparent conflict herewith. In determining whether or not the interest paid
or payable, under any specific circumstance, exceeds the maximum amount
permitted under applicable law, the parties to the Net Profits Documents shall
to the greatest extent permitted under applicable law: (a) characterize any
non-principal payment as an expense, fee or premium rather than as interest, (b)
exclude voluntary prepayments and the effects thereof, and (c) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the interest bearing obligation in accordance with the
amounts thereof outstanding from time to time and the maximum legal rate of
interest from time to time in effect under applicable law in order to lawfully
charge the maximum amount of interest permitted under applicable law. In the
event applicable law provides for an interest ceiling under Chapter 303 of the
Texas Finance Code, that ceiling shall be the "weekly ceiling" as defined in the
Texas Finance Code. As used in this section the term "applicable law" means the
laws of the State of Texas or the laws of the United States of America,
whichever laws allow the greater interest, as such laws now exist or may be
changed or amended or come into effect in the future.

         8.7. Severability. If any term or provision of any Net Profits Document
shall be determined to be illegal or unenforceable, all other terms and
provisions of the Net Profits Documents shall nevertheless remain effective and
shall be enforced to the fullest extent permitted by applicable law.

                                       26


         8.8. No Third Party Beneficiaries. No Person other than the Parties
hereto is an intended beneficiary of this Agreement or any portion hereof, and
there are no Third Party beneficiaries.

         8.9. Dispute Resolution. Any dispute or controversy between the Parties
arising out of or related to this Agreement or the transactions contemplated
hereunder shall be finally settled by binding arbitration between the Parties
pursuant to commercial arbitration rules of the American Arbitration
Association. The arbitration shall be conducted in Denver, Colorado, before a
single arbitrator. In the event the disputing Parties are unable to agree upon
an arbitrator within fifteen (15) days of the notice of arbitration, the
American Arbitration Association shall select an arbitrator for the Parties. The
arbitration award may be enforced by application to any court of competent
jurisdiction. Except as may otherwise be awarded by the arbitrator, the
prevailing party in any such proceeding shall be entitled to recover, its
reasonable attorneys' fees incurred in connection with such proceeding.

         8.10 Development of Formations Outside the JVEA. Subject to any
limitations contained in the JVEA, Company shall have the right in its sole
discretion at any time and from time to time to drill, complete and operate oil
and gas wells in the Contract Area, free and clear of the terms of this
Agreement; provided, however that this Section 8.10 shall not permit the
drilling by the Company of a well within the Production Unit of either an
Accepted Well or an anticipated Offered Well, unless Company's well is drilled
solely to test and produce formations that are not subject to the JVEA or this
Agreement and such testing or drilling does not affect Hydrocarbon Production
from any Accepted Well.

         8.11 Assignment. None of the Parties shall assign this Agreement or any
of its rights or obligations hereunder without the prior written consent of the
other Parties and any assignment made without such consent shall be void.
Company acknowledges and agrees that the restrictions in this Section shall not
apply to the Net Profits Interest after execution and delivery of the
Conveyance.
