     such conflicts or concerns within 15 days after the above-mentioned notice
     and either (A) jointly modify the Exploration Area, or (B) CamWest shall
     select another Exploration Area pursuant to this Section 2.1. CamWest may
     initially select only two Exploration Areas, but may select an additional
     Exploration Area once Pinnacle has commenced performing a SFD Survey on an
     Exploration Area, it being the intent that without the mutual consent of
     the parties there shall be only two unsurveyed Exploration Areas at any one
     time.

          2.2  CONDUCTING THE SFD SURVEYS. Pinnacle shall conduct the SFD Survey
     in the Exploration Areas in the order of priority that is established from
     time to time by CamWest; provided, however, that Pinnacle shall not be
                              --------  -------                            
     obligated to conduct actual surveying operations on more than one
     Exploration Area at any given time.  Camwest shall provide to Pinnacle any
     base maps and nonproprietary  data available to Camwest concerning each
     Exploration Area.  Pinnacle shall devote at least the Applicable Percentage
     of its worldwide SFD Survey capacity  for CamWest pursuant to this Section
     2.2 until 36 Exploratory Prospects (the "Minimum Prospect Inventory") have
     been accepted by CamWest.  When the first test well is spudded on an
     Exploratory Prospect, such Exploratory Prospect shall no longer be included
     in the calculation of Minimum Prospect Inventory.  Whenever the number of
     remaining Exploratory Prospects falls to or below 30,  Pinnacle shall
     devote at least the Applicable Percentage of its worldwide SFD Survey
     capacity  for CamWest pursuant to this Section 2.2 until such time as the
     Minimum Project Inventory is again achieved.  Pinnacle shall conduct each
     SFD Survey utilizing the SFD Technology in a professional and diligent
     manner.   Pinnacle shall use individuals who have the capability and
     expertise to conduct each SFD Survey.  The costs of each SFD Survey shall
     be apportioned as follows:

               (a)  Pinnacle shall contribute 100% of the associated internal
          costs, including data acquisition, data processing, data
          interpretation, administrative, research and development, and salaries
          of its and its Affiliates' employees; and

               (b)  CamWest shall pay 100% of Pinnacle's direct external data
          acquisition costs for the SFD Surveys, including aircraft rental
          payments, pilots' fees (or in the event the plane is owned or leased
          by Pinnacle or the pilot is an employee of Pinnacle, then the actual
          allocated cost of such plane and pilot but in no event greater than
          the amount of money equal to the arms-length rental costs of a
          comparable plane and/or pilot), and 100% of the reasonable travel
          expenses of Pinnacle's and its Affiliates' employees incurred in
          performing the SFD Survey; provided, however, that the costs described
                                     --------  -------  
          in this Section 2.2(b) shall not include salaries of Pinnacle's or its
          Affiliates' employees.

Page 4 of 22

 
          Upon the reasonable request of CamWest Pinnacle will resurvey any
     portion of an Exploration Area provided that the parties will bear the
     costs of such resurvey as set forth in this Section 2.2.

          2.3  CONVEYANCE OF DATA.  Provided that at no time shall Pinnacle  be
     obligated to spend more than the Applicable Percentage of its worldwide SFD
     Survey capacity pursuant to this Agreement, Pinnacle agrees that within 120
     days after CamWest informs Pinnacle of an Exploration Area pursuant to
     Section 2.1 above (or if a joint meeting was called to modify the
     Exploration Area, then within 120 days of the resolution achieved pursuant
     to Section 2.1(A), or such longer period as may be required by Pinnacle,
     provided that Pinnacle is making the Applicable Percentage of its world-
     wide SFD Survey capacity available pursuant to this Agreement) with respect
     to such Exploration Area Pinnacle shall at no cost to CamWest (except as
     set forth in Section 3) allow Camwest to view  the visual SFD Profiles and
     deliver to Camwest a map of flight lines and locations of  major anomalous
     features, whether or not they comprise SFD Anomalies.  Pinnacle shall
     provide written interpretations and recommendations on those anomalous SFD
     features that Pinnacle presents as the major SFD Anomalies in an
     Exploration Area.  The data and information specified in this Section 2.3
     are collectively referred to as the "SFD Information".

          2.4  REVIEW OF DATA.  Within 90 days after Pinnacle presents CamWest
     with the SFD Information pursuant to Section 2.3 (the "Evaluation Period"),
     CamWest shall:

               (a)  review each Exploration Area to delineate and accept one or
          more Exploratory Prospects within such Exploration Area. After the end
          of the Evaluation Period for each Exploration Area, the corresponding
          Buffer Zone will be a part of such Exploration Area only to the extent
          that it overlaps with an Exploratory Prospect. Any SFD Anomaly
          disclosed by the SFD Information but not included within an
          Exploratory Prospect shall be deemed a "Rejected Anomaly" and be
          thereafter governed by Section 11;

               (b)  use all reasonable efforts to perform an economic analysis
          of each Exploratory Prospect utilizing conventional oil and gas
          industry evaluation techniques, which analysis shall be conducted in a
          professional manner using qualified personnel; and

               (c)  provide Pinnacle with the results of such economic analysis;
          provided, however, that (i) CamWest makes no representations or
          -------- -------   
          warranties with respect to the accuracy of the economic analysis, (ii)
          Pinnacle shall perform its own independent analysis prior to making
          its election under Section 3.2, and (iii) CamWest shall in no event be
          liable to Pinnacle, its Affiliates, or any Third Party for the
          accuracy of the economic analysis.

          2.5  REVIEW OF EXPLORATORY PROSPECTS. CamWest may utilize conventional
     oil and gas industry methods to perform further evaluation work with
     respect to each Exploratory Prospect. CamWest may in its sole discretion
     decide whether or not the

Page 5 of 22

 
     drilling of a test well on such Exploratory Prospect is warranted. If
     CamWest provides written notice to Pinnacle of CamWest's election not to
     drill a test well on an Exploratory Prospect, it shall include an
     explanation for such election with reasonable particulars and then such
     Exploratory Prospect shall (A) be deemed a "Rejected Anomaly," and (B) not
     count toward the Minimum Project Inventory.

          2.6  SECURING PETROLEUM AND NATURAL GAS RIGHTS. If after reviewing an
     Exploratory Prospect pursuant to Section 2.5 CamWest decides in its sole
     discretion to drill a test well, CamWest shall use prudent and reasonable
     efforts to secure the Petroleum and Natural Gas Rights to all or any
     portion of the Exploratory Prospect, such rights to be held pursuant to the
     terms and conditions of this Agreement and the Operating Agreement. If
     CamWest, after reasonable efforts, cannot secure satisfactory Petroleum and
     Natural Gas Rights to an Exploratory Prospect then such Exploratory
     Prospect shall be deemed a "Key Tract" as evidenced by a written
     designation delivered by CamWest to Pinnacle. If CamWest cannot secure
     satisfactory Petroleum and Natural Gas Rights to the Key Tract within two
     years from the date the Exploratory Prospect is designated a Key Tract,
     such Exploratory Prospect shall become a Rejected Anomaly, and the rights
     with respect to such Rejected Anomaly shall be governed by Section 11 of
     this Agreement. If the Parties secure the Petroleum and Natural Gas Rights
     to the Key Tract within the two years from the date the Exploratory
     Prospect is deemed to be a Key Tract, such Key Tract shall be subject to
     the terms of this Agreement, including the payment provisions contained in
     Section 3.

          2.7  EXCLUSIVITY. Pinnacle agrees that without the prior written
     consent of CamWest, Pinnacle will not conduct any SFD Surveys for any Third
     Party on the areas (the "Exclusive Areas") described on Exhibit B, attached
                                                             ---------  
     hereto and made a part hereof, which may be amended from time to time by
     mutual agreement of the Parties but in no event shall the Exclusive Areas
     ever (i) cover any areas in Canada, (ii) collectively exceed 1,000,000
     square miles within the United States and an additional 1,000,000 square
     miles elsewhere in the world or (iii) number more than 25 for the United
     States and an additional 25 for the rest of the world.  Similarly, after an
     Exploration Area or Exploratory Prospect has been established pursuant to
     this Agreement, Pinnacle may not conduct an SFD Survey within such area or
     prospect for any Third Party.

     3.   PINNACLE'S INTEREST.  Pinnacle shall be entitled to the following
interest:

          3.1  INITIAL INTEREST. Unless and until Pinnacle elects to be a
     Royalty Interest owner with respect to any Exploratory Prospect, it shall

     following terms:

               (a)  The interest shall be 45% proportionately reduced in the
          event CamWest's working interest in the Exploratory Prospect (on a
          property by property basis) is less than 100%, provided that if
          Pinnacle desires to participate for less than a 45% Working Interest,
          it may do so if it so notifies CamWest on or before the times set
          forth in Section 3.2; and

               (b)  Pinnacle shall contribute directly its pro rata share of all
          costs in developing the Exploratory Prospect including costs
          associated with land acquisition, drilling, completion, surface
          facilities, lease operations; provided, however, that Pinnacle shall
                                        --------  ------- 
          not be required to contribute any seismic, geological, or geophysical
          costs or other costs described in Section 2.2(b).

          authority, or arbitrator other than those set forth in Exhibit G;
                                                                 --------- 

               (d)  Pinnacle has good and marketable title to, or a valid
          leasehold interest in, the properties and assets (other than rights
          licensed to Pinnacle and its Affiliates, including rights licensed
          under the License) used by them, located on their premises, or shown
          on their most recent balance sheet, or acquired after the date
          thereof, free and clear of all security interests, except for
          properties and assets disposed of in the ordinary course of business
          since the date of the most recent balance sheet.  With respect to

          licensed under the License, Pinnacle and its Affiliates have good and
          marketable title to such licensed rights (subject to the terms of the
          applicable license agreement) used by them or shown on their most
          recent financial statements or acquired after the date thereof.

               (e)  Pinnacle and its Affiliates own or have the right to use
          pursuant to license, sublicense, agreement, or permission all

          understands that neither Pinnacle and its Affiliates nor Momentum has
          patent protection with respect to the SFD Technology, and nothing in
          this representation or this Agreement shall be construed to require
          Pinnacle and its Affiliates or Momentum to obtain such patent
          protection.

               (f)  To the actual knowledge of Pinnacle, with no obligation to

          Affiliates has ever received any charge, complaint, claim, demand or
          notice alleging any such interference, infringement, misappropriation
          or violation (including any claim that any of Pinnacles or its
          Affiliates must license or refrain from using any intellectual
          property rights of any third party).  Notwithstanding the foregoing,
          CamWest understands that neither Pinnacle nor its Affiliates or
          Momentum represent that the SFD Technology does not interfere with,
          infringe upon, misappropriate or violate the intellectual property
          rights of third parties (although none of Pinnacle, its Affiliates or
          Momentum have any actual knowledge of any such infringement), and
          nothing in this representation or this Agreement shall be construed to
          mean that Pinnacle or its Affiliates or Momentum have made any such
          representation.

     8.   ARBITRATION.
          ----------- 

          8.1  SUBMISSION TO ARBITRATION. The Parties hereby submit all
controversies, claims and matters of difference arising under this Agreement
(other than those, if any, relating to ownership of the SFD Technology or SFD
Data) to arbitration. Without limiting the generality of the foregoing, the
following shall be considered controversies for this purpose: (a) all questions
relating to the interpretation or breach of this Agreement, (b) all questions
relating to any representations, negotiations and other proceedings leading to
the execution hereof, and (c) all questions as to whether the right to arbitrate
any such question exists.

          8.2  INITIATION OF ARBITRATION AND SELECTION OF ARBITRATORS. The Party
desiring arbitration shall so notify the other Party, identifying in reasonable
detail the matters to be arbitrated and the relief sought. Arbitration hereunder
shall be before a three-person panel of neutral arbitrators. The American
Arbitration Association (the "AAA") shall submit a list of potential arbitrators
and the Parties shall select three arbitrators in the manner established by the
AAA. In the event that any Party fails to select arbitrators as required above,
the AAA shall select such arbitrators. The arbitrators shall be entitled to a
fee commensurate with their fees for professional services requiring similar
time and effort. If the arbitrators so desire they shall have the authority to
retain the services of a neutral judge or attorney (whose fees shall be treated
as an arbitrator's fees) to assist them in administering the arbitration and
conducting any hearings and taking evidence at such hearings or otherwise.

          8.3  ARBITRATION PROCEDURES. All matters arbitrated hereunder shall be
arbitrated in Denver, Colorado, pursuant to Colorado law, and shall be conducted
in accordance with the Commercial Arbitration Rules of the AAA, except to the
extent such rules conflict with

Page 11 of 22

 
the express provisions of this Section 8 (which shall prevail in the event of
such conflict); provided, however, that all substantive law issues relating to
                --------  -------    
the rights and obligations of the parties under this Agreement shall be governed
by Section 13.15. The arbitrators shall conduct a hearing no later than 45 days
after submission of the matter to arbitration, and a decision shall be rendered
by the arbitrators within 10 days of the hearing. At the hearing, the Parties
shall present such evidence and witnesses as they may choose, with or without
counsel. Adherence to formal rules of evidence shall not be required but the
arbitration panel shall consider any evidence and testimony that it determines
to be relevant, in accordance with procedures that it determines to be
appropriate. Any award entered in an arbitration shall be made by a written
opinion stating the reasons for the award made.

          8.4  ENFORCEMENT. This submission and agreement to arbitrate shall be
specifically enforceable. Arbitration may proceed in the absence of any Party if
notice of the proceedings has been given to such Party. The Parties agree to
abide by all awards rendered in such proceedings. Such awards shall be final and
binding on all Parties to the extent and in the manner provided by Colorado law.
All awards may be filed with the clerk of one or more courts, state, federal or
foreign having jurisdiction over the Party against whom such award is rendered
or its property, as a basis of judgment and of the issuance of execution for its
collection. No Party shall be considered in default hereunder during the
pendency of arbitration proceedings specifically relating to such default.

          8.5  FEES AND COSTS. The arbitrators' fees and other costs of the
arbitration and the reasonable attorney fees, expert witness fees and costs of
the prevailing Party shall be borne by the non-prevailing Party. In its written
opinion, the arbitration panel shall, after comparing the respective positions
asserted in the arbitration claim and answer thereto, declare as the prevailing
Party the Party whose position was closest to the arbitration award (not
necessarily the Party in favor of which the award on the arbitration claim is
rendered) and declare the other Party to be the non-prevailing Party. The
arbitration award shall include an award of the fees and costs provided by this
Section 8.5 against the non-prevailing Party.

advantage of any of its rights hereunder, shall not be construed as a waiver of
any provisions or relinquishment of any such rights, but the same shall continue
and remain in full force and effect. All remedies afforded under this Agreement
shall be taken and construed as cumulative and in addition to every other remedy
provided for herein and by law.

          13.9.  SECTION HEADINGS. The section headings contained in this
