between  Executive  and the  Company  or any of the  Company's  subsidiaries  or
affiliates.

                                    RECITALS:

         WHEREAS,  the Board desires to provide for the continued  employment of
Executive and to make certain  changes in  Executive's  employment  arrangements
with the Company which the Board has determined will reinforce and encourage the
continued  attention  and  dedication to the Company of Executive as a member of
the  Company's  management,  in  the  best  interest  of  the  Company  and  its
shareholders.  Executive  is willing to commit  himself to continue to serve the
Company,  on the terms and conditions  herein provided,  although this Agreement
may be amended at any time by written agreement among the parties; and

         WHEREAS,  in order to effect the  foregoing,  the Company and Executive
wish to enter into an employment agreement on the terms and conditions set forth
below,

         NOW  THEREFORE,  in  consideration  of the premises and the  respective
covenants and  agreements of the parties herein  contained,  and intending to be
legally bound hereby, the parties hereto agree as follows:

1.       TIME AND EFFORTS

         1.1  Executive  shall be  employed  as the  Company's  Chief  Financial
Officer and Executive Vice  President and shall devote his full-time  attention,
except  as  allowed  in  subsections  1.3  and  1.6  below,  to the  duties  and
responsibilities  of Chief  Financial  Officer and Executive  Vice  President in
furtherance  of the Company's  business.  Subject to  consultation  with and the
direction of the Board of Directors,  Executive  shall have full  responsibility
for,  and specific  authority  as  described  in the bylaws of the  Corporation,
Article V, Section 11.0 (Attached-Exhibit A).

         1.2 In the  performance  of  all  of  his  responsibilities  hereunder,
Executive  shall  be  subject  to all  of the  Company's  policies,  rules,  and
regulations applicable to its officers and employees generally.  Executive shall
report to the President and Chief Executive Officer.

         1.3 Without the prior express  authorization of the Board,  which shall
not  unreasonably  be withheld,  Executive  shall not,  directly or  indirectly,
during the Term of this  Agreement  engage in any activity  competitive  with or
adverse to the Company's  business,  whether alone,  as a partner or independent
contractor,  or as an officer,  director,  or employee of any other corporation.
This  Agreement  shall not be  interpreted  to  prohibit  Executive  from making
passive personal  investments,  conducting private business affairs, or engaging
in educational or charitable  activities,  if those activities do not materially
interfere with the services required hereunder.  Subject to the reasonable prior
approval  of the  Board,  Executive  may  act as a  director  of any  profit  or
non-profit  corporation  or  other  business  entity,  if such  activity  is not
inconsistent with the business of the Company.  Executive's oil and gas holdings
are detailed in Exhibit B of this agreement.

         1.4 In order to  induce  the  Company  to enter  into  this  Agreement,
Executive  represents  and warrants to the Company  that (i)  Executive is not a
party or subject  to any  employment  agreement  or  arrangement  with any other
person,  firm,  company,  corporation  or  other  business  entity  which  is in
competition  with the Company;  and (ii)  Executive is subject to no  restraint,
limitation  or  restriction  by virtue of any  agreement or  arrangement,  or by
virtue of any law or rule of law or  otherwise  which would  impair  Executive's
right or  ability to enter the  employ of the  Company  or to perform  fully his
duties and obligations pursuant to this Agreement.

         1.5 Without first obtaining the written permission of the Board in each
instance,  Executive  will not  authorize  or permit  the  Company to engage the
services,  of, or engage in any business activity with, or provide any financial
or other  benefit to, any  affiliate  of  Executive.  The phrase  "affiliate  of
Executive" as used in this Agreement shall mean and include  Executive's  family
by blood or marriage (including, without limitation,  parents, spouse, siblings,
children and in-laws),  and any business or business entity which is directly or
indirectly owned or controlled by Executive or any member of Executive's  family
or in which  Executive  or any  member of  Executive's  family has any direct or
indirect financial interest whatsoever.

         1.6 Executive  may procure  outside  consulting  clients in accordance
with subsection 1.3 above.

Company's offices in Englewood,  Colorado or elsewhere,  or to be present in the

12/31/2004,  this Agreement  shall be  automatically  extended for an additional
one-year Term from such anniversary  date unless the Company notifies  Executive

Company  will not be renewing  this  Agreement  on the next  anniversary  of the
Effective  Date, or unless sooner  terminated  pursuant to Section 4. References
hereinafter to the "Term" of this Agreement shall refer to both the initial term
and any extended term of Executive's employment hereunder.

3.       COMPANY'S AUTHORITY

         Executive  agrees to observe and comply with the  reasonable  rules and
regulations  of Company as adopted by the Board of  Directors  of the Company or
committee of the Board of Directors respecting performance of Executive's duties
and to carry out and perform orders, directions, and policies of Company as they
may be, from time-to-time, stated to Executive either verbally or in writing.

         4.4  The  Company  may  terminate  Executive's  employment  under  this
Agreement  at any time  without  Cause,  on at least  ninety (90)  working  days
written  notice,  subject to provisions for payment of compensation as specified

diminish  Executive's  responsibilities  without  Cause,  (ii) fail to  maintain

terminate Executive's employment hereunder.

         4.7      Upon the expiration of the Term of this Agreement, or any

<PAGE>

5.       CURRENT COMPENSATION

         5.1 Annual Salary.  For all services  rendered by Executive  under this
Agreement, the Company shall pay or cause to be paid to Executive, and Executive
shall  accept  the Annual  Salary and  Incentive  Compensation,  if any,  all in
accordance with the subject to the terms of this Agreement. For purposes of this
Agreement,  the term  "Compensation"  shall  mean the  Annual  Salary  and Bonus
Compensation,  if any.  Executive  shall  be  entitled  to  receive  as  current
compensation  an  Annual  Salary  in  an  amount  of  not  less  than  $175,000.
(Hereinafter  referred to as the  "Salary").  References  in this  Agreement  to
"annual"  or "per  annum"  or  "Annual"  and  similar  phrases  shall  mean  the
twelve-month  period  commencing  on January 1st of each year during the Term of
this Agreement unless otherwise indicated.

         5.2 Bonus  Compensation.  Executive  shall also be  entitled  to annual
incentive  compensation  ("Bonus  Compensation") equal to 0.5% of the sum of the
Company's net after-tax  earnings as reported in the Company's  audited year-end
financial statements plus interest expense,  deferred taxes, depletion expenses,
depreciation  expenses,  amortization  expenses, and exploration expenses (which
sum  is  hereinafter  referred  to as  "cash  flow").  The  parties  agree  that
exploration  expenses  would be deducted from net after-tax  earning only if the
Company has elected the  "successful-efforts"  accounting method; if the Company
has  elected the  "full-cost"  accounting  method,  exploration  expenses  would
already be deducted in the computation of the Company's net after-tax  earnings,
subject to the additional provisions forth in Sections 5.2.1 and 5.2.2 below. In
addition,  prior to January 31 of each year  during the Term of this  Agreement,
Executive  and the Company shall  mutually  agree to a  performance-based  bonus
plan.  Such  bonus  plan  shall be  based  on  mutually  agreeable  measures  of
performance.

                  5.2.1 The parties agree that Bonus  Compensation  payments are
intended to be based on cash flow from undrilled Company-owned  properties as of
June 22, 2001 and  undrilled  properties  acquired by the Company  subsequent to
June 22,  2001.  Should the Company  acquire  proven-producing  properties  with
existing  cash flows,  net income less the  hypothetical  income tax due thereon
plus  interest  expense,   deferred  taxes,  depletion  expenses,   depreciation
expenses,  amortization  expenses,  and exploration  expenses (which exploration
expenses would only be added if the Company has elected the "successful-efforts"
accounting  method)  attributable to the acquired,  proven-producing  properties
shall be deducted from the base amount upon which the cash flow is derived.

                  5.2.2 Should the Company acquire  proven-producing  properties
with  existing  cash flows,  the parties  agree to  negotiate in good faith with

                                       5
<PAGE>

respect to the development of a schedule of the declining  production profile of
such  properties.  The parties agree that the amount derived by multiplying  the
proven-production  stream,  as set forth in the schedule,  by the  corresponding
sales price,  less  corresponding  production costs shall be subtracted from the
cash flow upon which Bonus Compensation is based.

                  5.2.3 Bonus Compensation  payments due hereunder shall be made
within 15 days after the Company has received  the signed audit report  covering
the year-end financial statements.

         5.4 Payments of Current Compensation. The payment of Executive's Annual
Salary shall be made in monthly  installments on the then prevailing  paydays of
the Company.  Any payment for Incentive  Compensation will be made in accordance
with the Executive Incentive  Compensation Plan, and payment will be made in one
lump sum  concurrently  with payments made to others in senior  management.  All
payments are subject to the customary withholding tax and other employment taxes
as required with respect to compensation paid to an employee.

         5.5      Payment of Compensation on Termination.
                  5.5.1 Upon termination of Executive's  employment prior to the
expiration of this  Agreement,  if such  termination is pursuant to Section 4.1,
4.2, 4.5, 4.6, or 4.7 hereof,  Executive shall be entitled to any Annual Salary,
Bonus  Compensation,  and  vacation  accrued  but  unpaid  through  the  date of
termination of employment,  payable on the date of termination.  Executive shall
also be  entitled to  exercise  any vested Plan  options for a period of One (1)
Year following the termination of his employment hereunder.

                  5.5.2 Upon termination of Executive's  employment prior to the
expiration of this  Agreement,  if such  termination  is pursuant to Section 4.4
hereof,  Executive shall be entitled to any Annual Salary,  Bonus  Compensation,
and vacation  accrued but unpaid  through the date of termination of employment,
payable  on the  date  of  termination.  Executive  shall  also be  entitled  to
compensation in an amount equal to the greater of (i) Executive's  Annual Salary
for one year and (ii) Executive's  Annual Salary for the period from the date of
termination  through the remaining Term of this Agreement plus cash equal to the
greater amount of $250,000 or the amount that is to be  distributed  pursuant to
paragraph  5.5.4  (a)  below as if there  were a Board of  Director  Recommended
Change of Control.  The stock price used in calculating such amount in 5.5.4 (a)
shall be the average  closing  price for the thirty (30)  trading  days prior to
termination.  Executive  shall also be  entitled  to  exercise  any vested  Plan
options for a period of one year  following the  termination  of his  employment
hereunder.  The provisions of this Section 5.5.2 shall apply throughout the Term
of this  Agreement,  including  any period of extension in  accordance  with the
provisions of Section 2 above.

<PAGE>

                  5.5.3 If the Company fails to extend this  Agreement  pursuant
to Section 2 hereof  Company  shall pay to  Executive  cash equal to the greater
amount of $250,000 or the amount that is to be distributed pursuant to paragraph
5.5.4  (a)  below as if there  were a Board of  Director  Recommended  Change of
Control  on or  prior  to the  then  applicable  date of  expiration  in  effect
hereunder. The stock price used in calculating such amount in 5.5.4 (a) shall be
the  average   closing   price  for  the  thirty  (30)  trading  days  prior  to
termination..

                  5.5.4 In the event that this Agreement  terminates as a result
of a Change of Control (as hereafter  defined),  Executive  shall be entitled to
any Annual Salary,  Bonus Compensation,  and vacation accrued but unpaid through
the date of termination of employment,  payable on the date of termination. Upon
termination as a result of a Change of Control, Executive shall also receive the
following  additional  compensation  payable  in cash on the  date a  Change  of
Control occurs:

or series of transactions  that have been recommended to the shareholders of the

beneficial  owner  (within the meaning of Rule 13d-3 under the Exchange  Act) of
50% or more  of the  Company's  outstanding  common  stock,  without  the  prior
approval  of the  Board;  (iv)  during  any  period  of two  consecutive  years,
individuals who at the beginning of such period  constituted the entire Board of

stockholders,  of each new Director was approved by vote of at least  two-thirds
of the Directors then still in office who were Directors at the beginning of the
period;  (v) a change  of  control  of a nature  that  would be  required  to be

6. DETERMINATION OF DISABILITY; PAYMENT OF DISABILITY INSURANCE PREMIUMS

         6.1 In the event Executive's disability,  as defined in Section 4.6, is
in question,  and after written request by the Company,  Executive refuses to be
examined by his  regularly  attending  physician or if the  regularly  attending
physician fails to submit a report within 30 days after the examination has been
requested by the Company,  the  determination of disability shall be made by the
Company.

                                       8
<PAGE>

         6.2 Executive shall be entitled to the disability benefits available to
all  executive  employees  of the  Company.  It is the intent of the  Company to
establish a disability insurance program as soon as practicable.

7.       MISCELLANEOUS BENEFITS

         7.1 Medical  Insurance.  Executive  and his family shall be entitled to
participate in any medical,  dental,  vision, life, long-term disability,  other
insurance or employee  benefit  program  instituted or maintained by the Company
for the benefit of its executive  employees.  It is the intent of the Company to
establish a medical and dental insurance program as soon as practicable. Company
will pay 50% of the  premiums.  Executive  is required to pay his portion of the
premiums in accordance with health insurance contract.

         7.2 401(k)  plan.  Executive  shall be entitled to  participate  in the
Company's 401(k) or other similar retirement benefit plan. The Company agrees to
implement a 401(k) or other  similar  retirement  benefit  plan as soon as it is
reasonably  feasible,  based  on the  size  of the  Company  and  its  financial
condition.

         7.3 Payment of Benefits on Termination  of  Employment.  If Executive's
employment  with the  Company is  terminated,  Executive  shall be  entitled  to
maintain his employee benefits in accordance with his maximum COBRA rights.

         7.4 Business Expenses. Executive shall be reimbursed for all reasonable
expenses  incurred by Executive in  connection  with  Executive's  attendance of
business  meetings and  promotion  of Company  business,  including  the cost of
travel to and from the Company's offices,  upon presentation by Executive to the
Company  of an  expense  report  and  adequate  records  or other  documentation
substantiating  the  expenditures,  not less frequently  than monthly.  Any such
amounts  disallowed,  as a business  expense  for  federal  or state  income tax
purposes,  shall be deemed  additional  salary to  Executive.  The fact that the
Company may not reimburse Executive for an expense is not an indication that the
Company  determined  that the  expense  was not  incurred  on its  behalf  or in
connection with the Company's  business.  In addition,  upon  presentation of an
invoice by Executive to the Company,  an accountable  expense for automobile and
office  expense  (including  Executive's  home  office) is to be paid each month
during the Term of this Agreement.

         7.5 Additional Benefits.  Executive shall be entitled to participate in
all programs,  rights and benefits for which executive is otherwise  entitled to

                                       9
<PAGE>

any bonus plan,  incentive plan,  participation plan or extra compensation plan,
pension plan,  overriding  royalty plan,  profit  sharing plan,  life,  medical,
dental,  disability or other  insurance  plan or policy or other plan or benefit
the Company may provide for senior  executives  or for  employees of the Company
generally from time to time in effect during the term of this Agreement. For the
avoidance of doubt,  the rights granted or afforded to Executive  under any such
plans  shall be not less than the most  favorable  rights  and  highest  amounts
granted to employees of similar or lower  position with the Company and on terms
at least as favorable.

8.       VACATION

         During  each  calendar  year of the Term of this  Agreement,  Executive
shall be entitled to twelve (12) weeks  vacation  comprised of five (5) weeks of
paid  vacation  and  seven  (7) weeks of  unpaid  vacation.  Executive  shall be
entitled to receive payment for accrued  vacation not taken during each calendar
year during the Term of this  Agreement or may accrue such vacation for use in a
subsequent  calendar year;  however  Executive  shall be subject to a maximum of
three (3) weeks of accrued vacation.

9.       RESTRICTIVE COVENANTS

         9.1  Confidential  Information.  Executive  acknowledges  that  in  his
employment hereunder he occupies a position of trust and confidence.  During the
Term,  and  thereafter in  accordance  with the  provisions  of this  Agreement,
Executive shall not,  except as may be required to perform his duties  hereunder
as required by applicable  law, and except for  information  which is or becomes
publicly  available  other  than as a result  of a breach  by  Executive  of the
provisions  hereof,  disclose to others or use,  whether directly or indirectly,
any Confidential Information.  "Confidential Information" shall mean information
about the  Company,  its  subsidiaries  and  affiliates,  and  their  respective
suppliers,  clients  and  customers  that is not  disclosed  by the  Company for
financial  reporting purposes and that was learned by Executive in the course of
his employment hereunder,  including (without limitation) proprietary knowledge,
trade secrets, market research, data, formulae, information and supplier, client
and customer  lists and all papers,  resumes,  and records  (including  computer
records) of the documents  containing such Confidential  Information.  Executive
agrees to deliver or return to the Company, at the Company's request at any time
or upon  termination or expiration of his  employment,  or as soon thereafter as
possible,  all  documents,  computer  tapes and  disks,  records,  lists,  data,
drawings,  prints,  notes  and  written  information  (and all  copies  thereof)
furnished by the Company or any of its  subsidiaries  affiliates  or prepared by
Executive  during the Term of his  employment  by the Company.  The  obligations
hereof shall not apply to any  information  that is or becomes  public or in the
public domain by action of the Company or through no fault of Executive.

                                       10
<PAGE>

         9.2 Business  Diversion.  During the Term and for 12 months thereafter,
Executive shall not,  directly or indirectly,  influence or attempt to influence
customers or suppliers of the Company or any of its  subsidiaries  or affiliates
to divert their business to any  competitor of the Company,  to the exclusion of
the  Company.  However,  Executive  may  contract  with the same  customers  and
suppliers  after the Term  hereof so long as it is not to the  exclusion  of the
Company's relationships with such customers and suppliers.

         9.3  Non-Solicitation.   Executive  recognizes  that  he  will  possess
confidential   information   about  other  employees  of  the  Company  and  its
subsidiaries  and affiliates  relating to, among other things,  their education,
experience,  skills,  abilities,  compensation and benefits,  and  interpersonal
relationships with suppliers and customers of the Company.  Executive recognizes
that  the  information  he will  possess  about  these  other  employees  is not
generally known, is of substantial value to the Company, and will be acquired by
him because of his business  position with the Company.  Executive  agrees that,
during  the  Term  and for 12  months  thereafter,  he  will  not,  directly  or
indirectly,  solicit or recruit any employee of the Company, its subsidiaries or
affiliates  for the purpose of being  employed by him or by any other  person on
whose  behalf he is acting as an agent,  representative  or employee and that he
will not convey any such  confidential  information or trade secrets about other
employees of the Company, including its subsidiaries or affiliates, to any other
person.  However, if Executive's employment is terminated in accordance with the
provisions  of  Section  4.4,  nothing  herein  shall  prevent   Executive  from
soliciting or recruiting,  directly or  indirectly,  any employee of the Company
recruited to the Company by Executive.

         9.4 If Executive  breaches,  or threatens to commit a breach of, any of
the provisions of Section 9 (the "Restrictive  Covenants"),  the Company and its
subsidiaries shall have the right to seek the following:

                  9.4.1 Specific  Performance.  The right and remedy to have the
Restrictive   Covenants   specifically   enforced  by  any  court  of  competent
jurisdiction,  it being  agreed  that any  breach  or  threatened  breach of the
Restrictive  Covenants  would  cause  irreparable  injury to the  Company or its
subsidiaries  and that money  damages may not provide an adequate  remedy to the
Company or its subsidiaries.

                                       11
<PAGE>

                  9.4.2 Accounting. The right and remedy to require Executive to
account for and pay over to the Company or its subsidiaries, as the case may be,
all  compensation,  profits,  monies,  accruals,  increments  or other  benefits
derived or received by Executive as a result of any  transaction  constituting a
breach of the Restrictive Covenants.

                  9.4.3   Severability  of  Restrictive   Covenants.   Executive
acknowledges and agrees that the Restrictive  Covenants are reasonable and valid
in  geographic  and  temporal  scope  and in all  other  respects.  If any court
determines at any of the Restrictive Covenants,  or any part thereof, is invalid
or unenforceable,  the remainder of the Restrictive  Covenants shall not thereby
be  affected  and shall be given  full  effect  without  regard  to the  invalid
provisions.

                  9.4.4 Blue Penciling.  If any court determines that any of the
Restrictive  Covenants,  or any part thereof,  is  unenforceable  because of the
duration or geographic scope or such provision,  such court shall have the power
to reduce the duration or scope of such  provision,  as the case may be, and, in
its reduced form, such provision shall not be enforceable.

                  9.4.5 Enforceability of Jurisdictions. The obligations in this
Section 9 shall survive the termination of Executive's  employment or expiration
of this Agreement and shall be fully enforceable  thereafter.  Executive intends
to and hereby confers jurisdiction to enforce the Restrictive Covenants upon the
courts of any  jurisdiction  within  the  geographic  scope of such  Restrictive
Covenants.  If the  courts  of any one or more of such  jurisdictions  hold  the
Restrictive  Covenants  unenforceable  by reason of the breadth of such scope or
otherwise,  it is the intention of Executive that such  determination not bar or
in any way affect the right of the  Company  or its  subsidiaries  to the relief
provided  above in the courts of any other  jurisdiction  within the  geographic
scope  of  such  Restrictive  Covenants,  as to  breaches  of  such  Restrictive
Covenants in such other respective jurisdictions,  such Restrictive Covenants as
they relate to each jurisdiction being, for this purpose, severable into diverse
and independent Restrictive Covenants.
