Agreement, Contractor may be requested by NGS (through its duly authorized
representatives) to perform survey services utilizing its EM Technology anywhere
on the North American Continent. However the execution of this Agreement is not

NGS, unless as provided otherwise under this Agreement.


                                       2


      2.1.2 NGS will request the Contractor to supply the Services by delivering
to Contractor an outline Statement of Work. The Parties will thereafter use best
reasonable commercial efforts to negotiate a mutually agreeable Statement of
Work within sixty (60) days from Contractor's receipt of the outline Statement
of Work, or such other period as may be agreed between the Parties.

      2.1.3 The Parties shall conduct the negotiations for the Statement of Work
in good faith, except that the Contractor will not be required to agree to
perform Services as follows:

      (a) at times where Contractor's resources are unavailable or pre-committed
      pursuant to the terms of an existing fully executed written agreement with
      a third party, provided that Contractor shall give first priority to NGS
      for its next available resources or at the end of the existing commitment;
      or

      (b) which are for the benefit of a group in which NGS is less than a
      majority owner or a majority working interest owner. In particular
      Contractor will not be obliged to provide Services to NGS where NGS is
      acting as a sub-contractor for any other person or entity; or

      (c) where the Statement of Work requests less than fourteen (14) days of
      Services, such days being consecutive where reasonably practical for NGS;
      or

      (d) which are beyond the scope of the usual business of Contractor.

      2.1.4 In addition to its rights under section 2.1.3, the Contractor will
not be obliged to provide in excess of sixty (60) days of Services per Agreement
Year. For purposes of this paragraph, the delivery date to Contractor of a
Statement of Work proposed by NGS under Section 2.1.2, where Services are
ultimately delivered, shall be used in allocating the days of Service to any
particular Agreement Year.

      2.1.5 It is specifically understood between the Parties that no
performance is required hereunder except after agreement in writing to a
Statement of Work, this Agreement serving only to establish the terms and
conditions of performance pursuant to which any future services will be
performed.

2.2   Provision of the Services.

      2.2.1 Once the Parties have reached a mutually agreeable Statement of
Work, the Contractor shall commence the Services at such time as is specified in
the Statement of Work or as otherwise agreed between the Contractor and NGS. The
Parties will provide the resources specified in the Statement of Work to enable
the Contractor to provide the Services.


                                       3


      2.2.2 Subject to the provisions of section 12 regarding the Contractor's
Intellectual Property Rights, all of the Deliverables shall be solely owned by
NGS upon payment in full of any sums due to the Contractor under this Agreement
as set forth in the applicable Statement of Work.

      2.2.3 NGS will be responsible for providing the necessary permissions and
access to land, materials, resources, facilities and, where applicable,
personnel as specified in the Statement of Work to facilitate the provision of
the Services by the Contractor. In addition, NGS acknowledge the reliance placed
by the Contractor on the information contained in the Statement of Work relating
to the site where the Services are to be performed, and consequently NGS
warrants that such information is accurate to the best of NGS's knowledge and
belief.

      2.2.4 Once agreed, should either Party wish to alter any provision in the
Statement of Work, the Parties will negotiate in good faith with a view to
agreeing any appropriate alteration to costs, Deliverables or milestones. In the
absence of any agreement, the Parties will continue to comply with their
obligations as specified in the agreed Statement of Work.

      2.2.5 Notwithstanding anything agreed in the Statement of Work, the
Contractor will be entitled to refuse to supply the Services in any area which
it reasonably deems to be hazardous or unsafe.

      2.2.6 NGS and Contractor shall each appoint and maintain a competent
representative (hereinafter, a "Superintendent") to act on its behalf. The
Superintendent shall be authorized to act on behalf of NGS and Contractor
respectively in all matters concerning the Services and administration of this
Agreement. Superintendents shall be available for consultation at all reasonable
times, and all oral/or written communication shall be between these
representatives. Should a Party's Superintendent prejudice the proper and
efficient performance of the Services, the other Party may request his removal
and upon good cause shown, the Superintendent shall be removed and replaced as
soon as is reasonably practicable.

      Any suggestions or directions given by the NGS Superintendent shall be
given only to the Superintendent or other person in charge of Contractor's
Group.

      3.2.1 Contractor shall be entitled to submit invoices to NGS as provided

Contractor Costs. NGS will provide the Contractor with the items and reasons for
dispute promptly in writing. Additionally, NGS shall not be required to pay any
specific portion of an invoice if NGS has a bona fide disagreement as to the
appropriateness of that portion of the invoice in question, and, NGS will
provide the Contractor with the items and reasons for dispute promptly in
writing. Contractor will use reasonable commercial efforts to provide NGS with
information required to resolve any dispute. However, NGS agrees that should any
portion of an invoice be disputed, NGS shall pay the non-disputed portion in
accordance with the Statement of Work.

      3.2.3 Any amounts set out in the Statement of Work are exclusive of any
applicable local sales taxes (applicable in the state or country in which the
Services are conducted), which will be payable in addition by NGS. NGS shall not
be responsible for the payment of any direct or indirect value-added tax,
foreign country-imposed tax and any withholding taxes, duties, imports or any
similar tax.

      3.2.4 Without prejudice to any other remedies of the Contractor, in the
event that any amount due hereunder is not paid on the due date, Contractor may
charge NGS interest (both before and after any judgment) on the amount unpaid,
at the rate of 3% per annum above the Wells Fargo base rate from time to time
until payment in full is made, or, at the Contractor's option, suspend the
provision of the Services. This clause 3.2.4 does not apply to those invoice
amounts that NGS has disputed in accordance with section 3.2.2 above.

      3.2.5 The Contractor may invoice for 100% of Contractor Costs where the
Contractor is prevented from providing the Services in whole or in part for any
period as a result of:

      (a) any local statutory public holidays; or


                                       5


      (b) any acts or omissions of the NGS Group or any sub-contractor of the
      NGS Group; or

      (c) any extreme weather conditions as agreed between the Party
      representatives; or

      (d) an event of Force Majeure (as define in section 10 below).

      3.2.6 The Contractor will not invoice NGS for any Contractor Costs
incurred where the Contractor is prevented from providing the Services in whole
or in part for any period as a result of:

      (a) any acts or omissions of the Contractor or any sub-contractor of the
      Contractor; or

      (d) any lack or failure of equipment or other facilities to be provided by
      the Contractor.

      3.3 NGS shall not refuse to accept Deliverables in order to defer payment
of any invoice.

      3.4 Notwithstanding the foregoing provisions of this section, the
Contractor shall have the right to negotiate a mutually agreeable rate for
Services if;

      3.4.1 any of the Services are provided on oil and gas properties or
projects where NGS does not own a majority interest; or

      3.4.2 the Contractor agrees to provide Services in excess of sixty (60)
days per Agreement Year, but only with respect to that portion of Services that
exceed sixty days in such period.

4.    TERM

      This Agreement shall be for an initial term of five (5) years commencing
on the Effective Date, and may be extend for an additional five (5) year period
upon the mutual written agreement of the Parties. In order to facilitate any
extension of this Agreement beyond the initial term, the Parties will meet at
least three months prior to the end of the initial term to discuss the
appropriate commercial provisions relative to any extension.

5.    INDEPENDENT CONTRACTOR

      It is expressly understood and agreed that the relationship created by
this Agreement is that of the principal and independent contractor and not that
of principal and agent, master and servant, or employer and employee. Neither
Party nor its employees shall be deemed to be the employees of the other Party.
NGS shall designate the services and the ultimate results to be obtained, but
shall leave to Contractor the methods and details of performance, NGS being
interested only in the results obtained, and having no control over the manner
and methods of performance.


                                       6

not be entitled to seek contribution or indemnity for any such payments from
NGS. Contractor agrees that its worker's compensation insurance policy shall be
endorsed to designate NGS as an alternative employer and as a principal and
statutory employer or borrowing employer and shall be further endorsed to waive
unconditionally those underwriter's or insurer's rights of subrogation against
NGS.

6.    INSURANCE

      The Contractor agrees to procure and maintain at its sole cost and
expense, policies of insurance in the minimum amounts outlined on that certain
document identified as "Insurance Requirements for Contractor Services,"
attached hereto as Exhibit "A". Contractor will furnish to NGS certificates of

are changed or cancelled.

ACCORDINGLY, ALL SUCH IMPLIED REPRESENTATIONS, WARRANTIES, CONDITIONS,

                                       11


      11.2 The Receiving Party may disclose or use the Confidential Information
      without prior written consent of the Disclosing Party only to the extent
      such information is:

      11.2.1 already known to the Receiving Party as of the date of disclosure
      hereunder; or

      11.2.2 already in possession of the public or becomes available to the
      public other than through the act or omission of the Receiving Party in
      breach hereof; or

      11.2.3 required to be disclosed under applicable law or by a governmental
      order, decree, regulation or rule (provided that the Receiving Party shall
      give written notice to the Disclosing Party prior to such disclosure); or

      11.2.4 is acquired independently from a third party that, to the knowledge
      of the Receiving Party, has the right to disseminate such information at
      the time it is acquired by the Receiving Party; or

      11.2.5 is otherwise independently developed by the Receiving Party without
      any use of any of the Confidential Information of the Disclosing Party.

      11.3 The Receiving Party shall be entitled to disclose Confidential
      Information without the Disclosing Party's prior written consent to the
      following persons (the "Representatives"), to the extent the
      Representatives need to know such Confidential Information for the purpose
      of assisting the Receiving Party with the evaluation of the Transaction,
      are informed of the confidential nature of the Confidential Information
      and agree to be bound by the terms of this Agreement:

            (i)   employees, officers and directors of the Receiving Party; or

            (ii)  the Receiving Party's Affiliates and the employees, officers
                  and directors of such Affiliates; or

            (ii)  any professional consultant, advisor or agent retained by the
                  Receiving Party in connection with the provision or receipt of
                  the Services, provided such is not a competitor of the
                  Disclosing Party.

      11.4 The Receiving Party shall be responsible for ensuring that all of its
      Representatives to whom the Confidential Information is disclosed under
      this Agreement shall keep such information confidential in accordance with
      the terms of this Agreement and shall not disclose, divulge or use such
      Confidential Information in violation of this Agreement. The Receiving
      Party shall be responsible to the Disclosing Party for any breach of this
      Agreement by the Representatives of the Receiving Party.


                                       12


      11.5 The Confidential Information shall remain the property of the
      Disclosing Party, and, subject to the provisions of section 15.1.2, the
      Disclosing Party may demand the return thereof at any time upon giving
      written notice to the Receiving Party. Promptly after receipt of such
      notice, the Receiving Party shall return all of the original Confidential
      Information and copies thereof (both written and electronic) in its
      possession and in the possession of Representatives to whom it was
      disclosed pursuant to the terms hereof.

      11.6 If the Receiving Party becomes legally compelled to disclose any of
      the Confidential Information, the Receiving Party will provide the
      Disclosing Party with prompt notice so that the Disclosing Party may seek
      a protective order or other appropriate remedy. If such protective order
      or other remedy is not obtained, the Receiving Party will furnish only
      that portion of the Confidential Information which is legally required,
      and the Receiving Party will cooperate with the Disclosing Party's counsel
      at the Disclosing Party's cost to enable the Disclosing Party to obtain a
      protective order or other reliable assurance that confidential treatment
      will be accorded the same.

"Confidential Information" shall be defined as all information furnished by the
Disclosing Party or any Person (as hereinafter defined) acting with the
Disclosing Party or on its behalf, including without limitation, partners,
employees, agents, representatives, attorneys, accountants, and consultants
(collectively, "Disclosing Party's Representatives"), to the Receiving Party or
any Person (as defined below) acting on Receiving Party's behalf (collectively,
"Receiving Party's Representatives"), including without limitation, any
Deliverable to the extent only that it contains or is based on any such
furnished information or reflecting Contractor's review or evaluation of any
information furnished by NGS or any Person acting with NGS or on its behalf. The
term "Person" as used in this Agreement shall be interpreted broadly to include,
without limitation, any corporation, company, entity, trust, group, partnership
or individual. Notwithstanding the above, the obligation of confidentiality in
regards to the Deliverables shall apply only to Contractor Group provided that
the disclosure does not include any direct information as to the Contractor's
Intellectual Property Rights.

      Subject to the approval by NGS, this confidentiality obligation will
survive the expiration or termination of this Agreement for five (5) years after
such expiration or termination, provided that the Contractor may not disclose
any portion of the Deliverables, as defined under Confidential Information,
after such expiration or termination without the express written consent of NGS.


                                       13


      Except as to disclosures required by law or regulation, neither Party
shall make any press announcements or otherwise publish any matter connected
with this Agreement without the prior written consent of the other Party, which
approval shall not be unreasonably withheld.

12. INTELLECTUAL PROPERTY

      12.1 The Parties acknowledge that, except in relation to any specific
rights granted to NGS to make use of and disclose the Deliverables, no rights or
licenses are granted by this Agreement. In particular, no rights or licenses are
granted by this Agreement in or to the EM Technology or any other Intellectual
Property Rights owned or licensed by the Contractor, and all such rights shall
remain owned by the Contractor or its licensors.

      12.2 Any other provision in this Agreement to the contrary
notwithstanding, and in addition to all other indemnity provisions herein,
Contractor represents and warrants that the use or construction of any and all
tools, technology and equipment furnished by Contractor and used in the work
provided for herein does not infringe on any third party intellectual property
rights, and Contractor agrees to indemnify and hold the NGS Group harmless from
any and all claims, demands, and causes of action of every kind and character in
favor of or made by a patentee, licensee, or claimant of any rights or priority
to such tool, technology or equipment, or the use or construction thereof, that
may result from or arise out of furnishing or use of any such tool, technology
or equipment by Contractor in connection with the work, provided that the
Contractor is given immediate and complete control of such claims. The
Contractor shall have the right to replace or change all or any part of the
intellectual property in order to avoid any infringement.

      12.3 NGS agrees that the Contractor shall have the sole right to defend
any such claims and make settlements thereof at its own discretion, subject to
such settlement not adversely impacting NGS.

      12.4 In the event that any such infringement occurs or may occur, the
Contractor may at its sole option and expense:

      12.4.1 Modify or amend the intellectual property or infringing tool so
      that the same becomes non-infringing; or

      12.4.2 Replace the intellectual property or infringing tool by other
      intellectual property of similar capability; or

      12.4.3 Repay NGS all amounts received under this Agreement.


                                       14


13. DISPUTE RESOLUTION

      Except as provided herein, no civil action with respect to any dispute,
claim or controversy arising out of relating to this Agreement may be commenced
until this matter has been submitted to non-binding mediation at the American
Arbitration Association ("AAA"). The Parties will attempt to resolve any dispute
or claim arising out of or relating to this Agreement promptly through direct
negotiations. If the matter is not resolved within fourteen (14) days through
negotiation, either Party may commence mediation by providing to the AAA and the
other Party, a request for mediation, setting forth the subject matter of the
dispute, the specific details of the dispute, and the relief requested. The
Parties will mutually cooperate with AAA and with one another to select a
mediator from AAAs panel of neutral mediators and in scheduling the mediation
proceedings. The Parties stipulate and agree that they will participate in
mediation in good faith and that they will share equally in all costs relating
to the mediation, excluding each Party's own costs and expenses. All offers,
promises, conduct and statements, whether oral or written, made in the course of
the mediation by any of the Parties, their agents, employees, experts and
attorneys, and by the mediator and any AAA employee, are confidential,
privileged, and inadmissible for any purposes including impeachment in any
litigation or other proceeding involving the Parties, provided that the evidence
that is otherwise admissible or discoverable shall not be rendered inadmissible
or non-discoverable as a result of its use in the mediation. Any Party may seek
equitable relief prior to the mediation to preserve the status quo only, pending
the completion of the mediation process. Except for such an action to obtain
equitable relief, neither party may commence a civil action with respect to the
matter submitted to mediation until after the completion of the initial
mediation session, or forty-five (45) days after the date of filing the written
request for mediation, whichever occurs first. Mediation may continue after the
commencement of a civil action, if the parties so desire. The provisions of this
section may be enforced by any court of competent jurisdiction and the parties
seeking enforcement shall be entitled to an award of all costs, fees and
expenses, including attorney's fees to be paid by the party against whom
enforcement is ordered.

14.   TERMINATION


      14.1 Either party shall be entitled immediately to terminate this
Agreement and/or any Statement of Work by written notice to the other if:


      14.1.1 that other Party commits any material breach of the provisions of
this Agreement and fails to cure any material breach within twenty one (21) days
after receipt of a written notice giving full particulars of the material
breach. For the avoidance of doubt, any failure to pay any invoice or expense
identified in a Statement of Work when due will be a material breach of this
Agreement unless such failure to pay is due to a bona fide dispute as to the
invoice or expense as provided in clause 3.2.2; or


                                       15

Party; or


      14.1.3 the other Party makes any voluntary arrangement with its creditors
or becomes subject to an administration order or becomes or is declared
bankrupt; or


      14.1.4 the other Party goes into liquidation (except for the purposes of
amalgamation or reconstruction and in such manner that the solvent company
resulting therefrom effectively agrees to be bound by or assumes the obligations
imposed on that other Party under this Agreement); or


      14.1.5 the other Party suffers any analogous proceedings to those set out
in sections 14.1.2 to 14.1.4 above


      14.2  The Contractor may terminate this Agreement if:

      14.2.1 NGS has not submitted a bona fide SOW for utilization of the
Services of the Contractor at least once within the consecutive eighteen (18)
month period from the Effective Date, unless the failure to utilize the
Contractor's services hereunder is the result of the actions or inactions of the
Contractor in material breach of this Agreement or an event of Force Majeure.


15.   CONSEQUENCES OF EXPIRATION OR TERMINATION


      15.1 Upon expiration or termination of a Statement of Work or this

of any such Confidential Information and copies thereof that are in its
possession


      15.1.3 all sums accrued to the date of termination and due to be paid to
the Contractor relative to the Statement of Work or Agreement (as appropriate)
shall become immediately payable by NGS, except those charge that are the
subject of a bona fide dispute under clause 3.2.2.

15.2 Expiration or termination of a Statement of Work or this Agreement shall be
without prejudice to any accrued rights or liabilities of the parties and to the
continuation in force of all provisions which are expressed to or by implication
remain in force following expiration or termination or which would be intended
by the parties to continue beyond expiration or termination.


                                       16

a wholly-owned subsidiary of that Party, on giving the other Party written
notice to this effect.

18.   COOPERATION IN MARKETING.

      Subject to the prior written consent of NGS, not to be unreasonably
withheld, Contractor may utilize that portion of the Deliverables from the first
Statement of Work that lies solely and completely on oil and gas property in
which NGS owns a majority of the interest in the marketing of its
multi-transient electromagnetic survey technology. For clarity, Contractor may
not utilize any Deliverable that covers any property or depth that is not owned
by NGS. NGS shall reasonably cooperate in such efforts by providing references
and the disclosure of the Parties' participation in the Services.


                                       17


19.   LIENS

      Each Party will promptly pay any and all amounts owing by it for taxes,
licenses, fees levied or assessed and for work performed, services rendered or
materials furnished in connection with this Agreement so that no such claim or
lien will ever attach, or be permitted to attach, to the other Party's property,
whether real or personal, and each Party hereby indemnifies the other Party
against any and all such claims and liens. Notwithstanding the words of this
section, or any other section of this Agreement to the contrary, Contractor

owed Contractor by NGS, including the right to file, perfect or continue a lien
for work performed by Contractor under this Agreement.

10.   All insurance shall be carried in a company or companies with an A.M. Best
      rating of at least A+, or equivalent, and shall be maintained in full
      force and effect during the term of this Agreement, and shall not be
      cancelled, altered, or amended without thirty (30) days prior written
      notice having first been furnished NGS. NGS herein approves Chubb as an
      acceptable company.

11.   Additionally, to the extent Contractor assumes liability hereunder, and
      agrees to indemnify NGS, the NGS Group shall be named additional insureds
      in all such insurance policies (with exception of Workers' Compensation
      coverage) or shall be covered by an "indemnity to principals" clause, with
      all such insurance being primary to any insurance of NGS that may apply to
      any such occurrence, accident or claim.

12.   No "other insurance" provision shall be applicable to the NGS Group by virtue
      of having been named an additional insured, loss payee, or covered by an
      "indemnity to principals" clause under any policy of insurance.  Contractor
      agrees to furnish NGS a certificate or certificates evidencing coverage in
      accordance with the requirements of this Exhibit A and when requested by NGS,
      to furnish certified copies of all said insurance policies.  These
      requirements shall be conditions precedent to the payment of any sums that
      may be due Contractor.

13.   In the event Contractor is a self-insurer and NGS has consented to
      Contractor being a self-insurer as to any one or more of the risks as to
      which coverage is herein required, evidence of such consent must be in
      writing and approved by a representative of NGS authorized to enter into
      such consent agreement.


Any and all deductibles in the above described insurance policies shall be
assumed by, for the account of, and at Contractor's sole risk.
