  Company and its shareholders for the Company to continue its employment
  of the Employee.  The Board has determined that the Company should enter

       NOW, THEREFORE, in consideration of the background circumstances and

  Employee agrees to perform services for and continue in the employment of
  the Company on the terms and conditions set forth in this Agreement.

  2.  Term.  The term of employment will begin on the date of this
  Agreement and end three years later on December 31, 2003; provided,
  however, that beginning on December 31, 2001 and each December 31
  thereafter, the term of employment shall automatically be extended each
  such time, on the same terms and conditions, for one additional year
  beyond the end of the then-current term, unless not later than January 15
  of each year starting January 15, 2001 and continuing on each succeeding
  year, either party has given written notice to the other party that it
  elects not to extend the term.  For example, unless either the Company or
  the Employee elects in writing not to extend the term of employment by
  January 15, 2001, the term of employment will be extended to December 31,
  2004.  However, if either the Company or the Employee elects in writing
  not to extend the term of employment by January 15, 2001, the term of
  employment will end on December 31, 2003.

  3.  Position and Duties.  The Employee shall serve as the President and
  Chief Executive Officer of the Company with such duties, powers and
  responsibilities as the Board of Directors or Chief Employee Officer of
  the Company may reasonably specify from time to time.  The Employee shall
  devote all his working time and efforts to his responsibilities under
  this Agreement and to the business and affairs of the Company and its
  subsidiaries and affiliates in accordance with the standards of the
  industry, and shall not be employed by any other person or entity.

  4.  Place of Performance.  In connection with the employment, the
  Employee shall be based either at the principal executive offices of the
  Company, at the location of one of its other offices or plant locations
  in the Denver, Colorado metropolitan area, or at the offices of one of
  the Company's subsidiaries in the Denver, Colorado metropolitan area.

  5.  Compensation and Related Matters.

       5.1  Salary.  During the period of the Employee's employment
  hereunder, the Company shall pay the Employee a salary of not less than
  $__________ per annum.  The salary shall be paid in equal monthly
  installments, in advance.  This salary shall be increased annually
  according to an appropriate cost of living index for the Denver, Colorado
  metropolitan area, and shall not be reduced during the term of this
  Agreement.  Compensation of the Employee by salary payments shall not be
  deemed exclusive and shall not prevent the Employee from participating in
  any other compensation arrangement, deferred compensation plan, bonus or
  bonus plan, stock options, stock appreciation rights, similar executive
  compensation arrangements, or employee benefit plan of the Company.  The
  salary payments (including any increased salary payments) shall not in
  any way limit or reduce any other obligation of the Company under this
  Agreement or under other employee benefit plans.  No other compensation,
  benefit or payment to the Employee shall in any way limit or reduce the
  obligation of the Company to pay the Employee's salary under this
  Agreement.

       5.2  Expenses.  During the term of the Employee's employment, the

  reimbursed shall include costs of travel and living expenses while away
  from home on business or at the request of and in the service of the
  Company.

       5.3  Other Benefits.  The Employee shall continue to be entitled to
  participate in all of the Company's employee benefit plans and
  arrangements in effect on the date of this Agreement, or in substituted
  plans or arrangements providing the Employee with at least equivalent
  benefits.  The Company shall not make any changes in such plans and
  arrangements that would adversely affect the Employee's rights or
  benefits, unless such change occurs pursuant to a program applicable to
  all officers of the Company and does not result in a proportionately
  greater reduction in the rights or benefits of the Employee than those of
  any other executive officers of the Company.  The Employee shall also be
  entitled to participate in or receive benefits under any employee benefit
  plan or arrangement made available by the Company in the future to its
  executive officers, on a basis consistent with the terms, conditions and
  overall administration of such plans and arrangements.  Any payments or
  benefits payable to the Employee in respect to any calendar year or
  fiscal year during which the Employee is employed by the Company for less
  than the entire year shall, unless otherwise provided in the applicable
  plan or arrangement, be prorated in accordance with the number of days in
  the year during which he is so employed.

  of this Agreement only under the following circumstances:

       6.1  Death.  The Employee's employment hereunder shall terminate
  upon his death.

       6.2  Disability.  The Company may terminate the Employee's
  employment if Employee shall sustain a Disability (as subsequently
  defined in this Section) and be unable to perform his duties and
  responsibilities during the term of this Agreement, as shall have been
  certified by at least two duly licensed and qualified physicians, one
  approved by the Board of Directors of the Company and one approved by
  Employee (the Examining Physicians), and the Employee has been absent
  from his duties under this Agreement on a full-time basis for a period of
  six consecutive months.  "Disability" means the complete and total
  disability of Employee resulting from injury, sickness, disease, or
  infirmity due to age, whereby Employee is unable to perform his usual

  the Company's business, or intoxication while on duty resulting from use

  law, which could be materially damaging to the Company without reasonable
  good faith belief by the Employee that such conduct is in the best
  interests of the Company; or  (iii) Employee's final conviction of a
  felony involving moral turpitude.  If the Employee is advised that he is
  being terminated for Cause and within fifteen days thereafter submits to
  the Chief Executive Officer or Chief Operating Officer a written
  objection to such a determination, the termination will be rescinded and
  will not be effective unless the Board of Directors of the Company at or
  before its next regularly scheduled meeting determines by majority vote
  that the Employee was terminated for Cause.

       6.4  Termination by the Employee.  The Employee may terminate his
  employment under this Agreement with no breach:  (i) for Good Reason, as
  subsequently defined;  (ii) for purposes of retiring at age 65 or more,
  by giving written notice to that effect; or  (iii) if the Employee's
  health becomes impaired to an extent that he is unable to diligently and
  skillfully perform his employment duties or that makes his continued
  performance of his duties hazardous to his physical or mental health or
  his life, provided that the Employee has furnished the Company with a
  written statement from a qualified doctor to such effect and provided,
  further that, at the Company's request, the Employee submits to an
  examination by a doctor selected by the Company and such doctor concurs
  in the conclusion of the Employee's doctor. '

       For purposes of this Agreement, "Good Reason" shall mean:  (a) a
  decrease in the total amount of the Employee's annual salary below its
  level in effect for the previous twelve months, or a decrease, without
  the Employee's written consent, in the bonus share, based on the
  Company's profit-sharing plan, to which the Employee may be entitled, for
  the previous twelve months, provided, however, nothing herein shall be
  construed to guarantee a bonus award to the Employee; or  (b) a
  geographical relocation of the Employee without his written consent;  (c)
  a failure by the Company to comply with any material provision of this
  Agreement which has not been cured within ten days after notice of such
  noncompliance has been given by the Employee to the Company; or  (d) any
  purported termination of the Employee's employment which is not made
  pursuant to a Notice of Termination complying with the requirements of
  Section 6.5 (and for purposes of this Agreement no such purported
  non-complying termination shall be effective).

       6.5  Notice of Termination.  Any termination of the Employee's
  employment by the Company or by the Employee (other than termination
  pursuant to Section 6.1 shall be communicated by written Notice of
  Termination to the other party hereto.  For purposes of this Agreement, a
  "Notice of Termination" shall mean a notice which shall indicate the
  specific termination provision in this Agreement relied upon and shall
  set forth in reasonable detail the facts and circumstances claimed to
  provide a basis for termination of the Employee's employment under the
  provision so indicated.

       6.6  Date of Termination.  "Date of Termination" shall mean:  (i) if
  the Employee's employment is terminated by his death, the date of his
  death,  (ii) if the Employee's employment is terminated for Disability
  pursuant to Section 6.2, thirty days after Notice of Termination is given
  (provided that the Employee has not returned to the performance of his
  duties on a full-time basis during such thirty-day period),  (iii) if the
  Employee's employment is terminated for Cause pursuant to Section 6.3,
  the date specified in the Notice of Termination, and  (iv) if the
  Employee's employment is terminated for any other reason, the date on
  which a Notice of Termination is given.  If the party receiving a Notice
  of Termination notifies the other party that a dispute exists concerning
  the termination, the Date of Termination shall be the date on which the
  dispute is finally determined.  Such a dispute shall be finally
  determined either by mutual written agreement of the parties, by a
  binding and final arbitration award, or by a final judgment, order or
  decree of a court of competent jurisdiction (the time for appeal
  therefrom having expired and no appeal having been perfected).

  7.  Compensation Upon Termination.

       7.1  Death.  If the Employee's employment is terminated by his
  death, the Company shall continue to pay salary for a period of twelve
  months after the Date of Termination, at the Employee's last annual
  salary rate and subject to applicable tax withholding, to the Employee's
  personal representative, for the benefit of his spouse, or if none, his
  estate.  This sum shall be paid in semimonthly installments at the rate
  of salary in effect immediately before the death.  The installments shall
  start on the Company's regular payday following the death and continue on
  each regular payday thereafter until a total of twelve bi-monthly
  installments have been paid.

       7.2  Disability.  During any period that the Employee fails to
  perform his employment duties as a result of a Disability (Disability
  Period), the Employee shall continue to receive his full salary at the
  rate then in effect until his employment is terminated pursuant to
  Section 6.2, provided that payments made to the Employee during the first
  180 days of the Disability Period shall be reduced by the sum of the
  amounts, if any, payable to the Employee at or prior to the time of any
  payment under disability benefit plans of the Company and which were not
  previously applied to reduce any payment of salary.  If the Employee
  terminates his employment for disability under clause (iii) of Section
  6.4, the Company shall pay the Employee his full salary through the Date
  of Termination at the rate in effect at the time Notice of Termination is
  given, and as severance pay, an amount equal to the Employee's annual
  salary in effect as of the Date of Termination.  This payment shall be
  made in a lump sum on or before the 30th day following the Date of
  Termination.

       7.3  Cause.  If the Employee's employment is terminated for Cause,
  the Company shall pay the Employee his full salary through the date of
  delivery to him of a Notice of Termination.  Salary shall be paid at the
  rate in effect at the time Notice of Termination is effective, and the
  Company shall have no further obligations to the Employee under this
  Agreement.

       7.4  Company's Breach of Contract; Termination by Employee for Good
  Reason.  The Company's termination of employee's employment other than as
  provided in this Agreement, including a purported termination pursuant to
  Sections 6.2 or 6.3 that is disputed by the Employee and finally
  determined not to have been in accordance with this Agreement, shall be a
  wrongful termination by the Company in breach of this Agreement.  In the
  event of such a wrongful termination, or if the Employee shall terminate
  his employment for Good Reason, then:

       (a)  the Company shall pay the Employee his full salary
       through the Date of Termination at the rate in effect at
       the time Notice of Termination is given;

       (b)  the Company shall pay the Employee, as severance pay
       in lieu of further salary payments to the Employee for
       periods subsequent to the Date of Termination, an amount
       equal to three times the Employee's annual salary rate in
       effect as of the Date of Termination, in a lump sum on or
       before the 20th day following the Date of Termination; and

       (c)  the Company shall pay all other damages to which the
       Employee may be entitled as a result of the breach,
       including damages for all loss of benefits to the Employee
       under the Company's profit sharing plan, employee benefit
       plans and any supplemental retirement income plan that the
       Employee would have received if the Company had not
       breached this Agreement and had the Employee's employment
       continued for the full term provided in Section 2 of this
       Agreement, at the rate of compensation specified in this
       Agreement, and all legal fees and expenses incurred by him
       as a result of the termination.

  8.  Counsel Fees and Indemnification.

       8.1  Attorney Fees and Costs.  The Company shall pay, or reimburse
  to Employee, all reasonable costs incurred by him, including attorneys?
  fees and costs, in the following circumstances:  (i) if the Company
  terminates, or seeks to terminate this Agreement, alleging as
  justification for such termination a material breach by Employee or for
  Cause as described in Section 6.3, and Employee disputes such termination
  or attempted termination, and Employee prevails, or  (ii) if Employee
  elects to terminate his services hereunder for Good Reason as specified
  in Section 6.4 of this Agreement, and the Company disputes its obligation
  to pay to Employee the sums of money provided in Section 7.4, and
  Employee prevails.

       8.2  Indemnification.  The Company shall indemnify and hold Employee
  harmless as required by the Company's bylaws against judgments, fines,
  amounts paid in settlement and reasonable expenses, including attorneys'
  fees incurred by Employee, in connection with the defense of, or as a
  result of any action or proceeding (or any appeal from any action or
  proceeding) in which Employee is made or is threatened to be made a party
  by reason of the fact that he is or was an officer of the Company.
  Indemnification shall be provided regardless of whether such action or
  proceeding is one brought by or in the right of the Company, to procure a
  judgment in its favor (or other than by or in the right of the Company).
  These obligations of the Company are independent of, and shall not be
  limited or prejudiced by, the Company's other undertakings specified in
  this Section 8.

       8.3  Insurance.  The Company will exert reasonable efforts, if the
  Board of Directors deems it practical and advisable, to obtain and
  maintain officers' and directors' liability insurance, in amounts and
  coverages deemed advisable by the Board of Directors.  The Company will
  include Employee among those covered and insured up to the maximum limits
  provided by any such insurance.

  9.  Non-Competition.

       9.1  Covenant Not To Compete.  The Company and the Employee
  recognize that the services to be rendered to the Company by the Employee
  under this Agreement are special, unique and of extraordinary character
  in that the Employee has been involved in creating and developing its
  business contracts and customers and in developing and marketing its
  patented and proprietary gas-to-liquids process.  Therefore, during the
  term of this employment hereunder and for three years following the
  termination for such employment for any reason whatsoever (the
  "Non-Competition Period"), if the Employee receives all compensation to
  which he is entitled under this Agreement, the Employee covenants and
  agrees not to, without the express written consent of the Company,
  directly or indirectly own, manage, operate, control, advise, lend money
  to, endorse the obligations of, or participate in or be connected as an
  officer, director, five percent or more stockholder of a publicly-held
  Company, or as a stockholder, employee, partner, agent, consultant or
  otherwise of a closely held company or of any enterprise or individual,
  that is engaged in the business of developing, manufacturing or marketing
  processes, technology, products or services that are similar to
  processes, technology, products or services which have been, or are being
  developed or are planned (as documented by memoranda, instruments,
  writings or other compilations of information of the Company) to be
  developed by the Company, and will not, in any manner, either directly or
  indirectly, compete with the Company in its business.  The Company may
  withhold its consent to any such proposed competition in its sole and
  absolute discretion.

       9.2  Non-Solicitation.  For a period of one year following
  Employee's termination of employment under this Agreement, Employee will
  not, without the express prior written approval of the Board  (i)
  directly or indirectly, in one or a series of transactions, recruit,
  solicit or otherwise induce or influence any proprietor, partner,
  stockholder, lender, director, officer, employee, sales agent, joint
  venturer, investor, lessor, supplier, licensee, customer, agent,
  representative or any other person which has a business relationship with
  the Company or had a business relationship with the Company within the
  twenty-four month period preceding the date of the Employee's termination
  of employment, to discontinue, reduce, or modify such employment, agency
  or business relationship with the Company, or  (ii) employ or seek to
  employ or cause any business organization in direct or indirect
  competition with the Company to employ or seek to employ any person or
  agent who is then (or was at any time within six months prior to the date
  the Employee or the competitive business employs or seeks to employ such
  person) employed or retained by the Company.  Notwithstanding the
  foregoing, nothing herein shall prevent the Employee from providing a
  letter of recommendation to an employee with respect to a future
  employment opportunity.

       9.3  Outside Business Activity.  The Employee, during the term of
  his employment by the Company hereunder, shall not undertake or engage in
  any other employment, occupation or business enterprise in which Employee
  actively participates.  Employee shall at all times keep the Company
  informed of any outside business activity by him, and shall not engage in
  any activity that may be in conflict with this Agreement or the Company?s
  business or its best interests.

  10.  Confidentiality.  The Employee acknowledges that, as a result of his
  employment by the Company, he has learned Confidential Information, as
  defined in Section 10.1, that is owned by the Company, and which is of a
  special and unique value and nature relating to the business of the
  Company.  In the course of his further employment by the Company,
  Employee will learn more Confidential Information and may add to the
  Confidential Information.  As a material inducement to the Company to
  enter into this Agreement and to pay the Employee the compensation
  described in this Agreement, the Employee agrees that he will not, except
  in the normal and proper course of his duties hereunder, disclose or use
  or enable anyone else to disclose or use, either during the
  Non-Competition Period (as defined in Section 9.1) or at any time
  thereafter, any such Confidential Information without the prior written
  consent of the Company.  The Company may withhold its consent in its sole
  and absolute discretion.

       10.1  Confidential Information.  "Confidential Information" is
  non-public information regarding the Company and its proprietary
  processes for the conversion of carbon-bearing solids, liquids and gases
  into valuable liquid hydrocarbons;  contractual licensing terms and
  arrangements; customers and potential customers; costs and performance
  data relating to the Company's catalysts and processes; patent
  applications; and trade secrets used in the Company's business that
  provide an advantage over competitors who do not know or use them,
  including computer software programs and source codes, engineering
  designs and specifications for the internal aspects of the synthesis gas
  reactor modules; secret formulae and composition of the Company's
  catalysts; and catalyst injection methods.

       10.2  Exception to Confidentiality.  It is agreed, as an exception
  to the foregoing obligations of confidentiality, that information
  received by the Employee as a result of his employment shall not be
  considered confidential, and he shall not be limited in disclosing the
  same, if and to the extent that the information, as shown by competent
  evidence:  (i) is or becomes, through no fault of the party obligated to
  maintain confidentiality, in the public domain;  (ii) is lawfully
  obtained by him from a source other than the Company or its agents;
  (iii) was already known to him at the time of its receipt, as shown by
  reasonable proof filed with the Company within a reasonable time after
  its receipt; or  (iv) required to be disclosed by law or order of any
  court or governmental authority having jurisdiction.  Disclosures that
  are specific, including but not limited to operating conditions such as
  pressures, temperatures, formulas, procedures and other like standards
  and conditions, shall not be deemed to be within the foregoing exceptions
  merely because they are embraced by general disclosures available to the
  general public or in the Employee's possession.  Additionally, any
  combination of features shall not be deemed to be within the foregoing
  exceptions merely because the individual features are available to the
  general public or in the Employee's possession unless the combination
  itself and its principle of operation are available to the general
  public.

       10.3  Published Disclosure.  It is agreed that the disclosure of
  certain information by the Company in a publication, such as in letters
  patent or by otherwise placing it in the public domain, will not free the
  Employee from his obligation to maintain in confidence any information
  not specifically disclosed in or fairly ascertainable from the
  publication or other disclosure, such as, for example, the fact that
  information in the publication or any portion of it is or is not used by
  either party.  The Employee shall have the right to publish information
  or articles pertaining to the Company's gas-to-liquids technology and its
  liquid hydrocarbon products only if such information is not confidential,
  and, with respect to Confidential Information, only upon prior written
  approval by the Company, which it may withhold in its absolute
  discretion.

       10.4  Non-Use After Termination.  The Employee shall not use the
  Confidential Information after termination or expiration of this
  Agreement unless and until such time as the information ceases being
  Confidential Information pursuant to the provisions of Section 10.2.

       10.5  Books and Records.  The Employee agrees that all documents and
  other tangible property of any nature pertaining to activities of the
  Company or to any Confidential Information, in his possession now or at
  any time during the period of his employment with the Company, including
  without limitation, financial data, formulae, processes, operating
  results of processes, notes, memoranda, notebooks, manuals, reports,
  studies, data sheets, records, blueprints, designs, electronic or
  mechanical data storage devices and records, and computer software
  programs and their source codes, are and shall be the property of the
  Company.  The Employee will return to the Company all originals and
  copies in his possession or control that contain such information,
  whenever requested by the Company from time to time during the
  Non-Competition Period and after termination of his employment.

  11.  Inventions and Discoveries.  The Employee and the Company agree
  that:

       11.1  Disclosure By Employee.  The Employee will promptly disclose
  to the Company in writing, complete and accurate information pertaining
  to each invention, discovery, improvement, device, design, apparatus,
  process, technological advance, innovation, idea, concept, method or
  product (the Inventions) whether patentable or not, and all writings,
  drawings, software, semiconductor mask, works and other works of
  authorship pertaining to these Inventions (Works of Authorship), whether
  copyrightable or not, made, developed, perfected, devised or conceived
  during his employment with the Company, or during the 12-month period
  following his employment by the Company, which are within or in any way
  related to the existing or contemplated scope (now or at any later time
  during such period), of the business of the Company, whether or not
  developed on the Employee's own time.  The determination of whether or
  not an Invention or Work of Authorship is within the contemplated scope
  of the business of the Company will be based on the documentary evidence
  of the Company, including all documents, memoranda, writings or other
  compilations of information of the Company relating to the scope of the
  business of the Company.  An Invention or Work of Authorship shall be
  deemed to have been made within such period of time if it is made or
  conceived within such period and results from or was suggested by the
  Employee's employment by the Company.

       11.2 Assignment By Employee.  The Employee will, upon request of the
  Company, assign to the Company or to any other party designated by the
  Company, all of his right, title and interest in and to any or all of
  said Inventions or Works of Authorship, any copyrights obtained thereon,
  and any patent applications filed thereon, together with all extensions,
  re-issues, and renewals thereof in this and all foreign countries and
  patents granted.  He will promptly execute all proper papers for these
  purposes as the Company may request, and for use in applying for,
  obtaining, and maintaining all such patents or copyrights at the expense
  of the Company.  The Employee's obligations to execute the papers and
  assignments specified in this Section shall continue beyond the period of
  his employment and shall bind his heirs, assigns, executors and other
  legal representatives.

  12.  Right To Injunctive Relief.  The Employee acknowledges that a breach
  by the Employee of any of the terms of Sections 9, 10 or 11 of this
  Agreement will cause irreparable harm to the Company, and that the
  Company shall therefore be entitled to any and all equitable relief,
  including, but not limited to, injunctive relief, and to any other remedy
  that may be available under any applicable law or agreement between the
  parties, and to recover from the Employee all costs of litigation
  including, but not limited to, reasonable attorneys' fees and court
  costs.  The parties hereto further agree that this Agreement shall be
  enforced wherever the Company is doing business at the termination of the
  Employee's employment hereunder and wherever the Company at such time
  reasonably foresees, plans and expects to do business during the
  Non-Competition Period.

  13.  Entire Agreement.  The Company and the Employee acknowledge that
  this Agreement contains the full and complete agreement between and among
  the parties, that there are no oral or implied agreements or other
  modifications not specifically set forth herein, and that this Agreement
  supersedes prior agreements or understandings pertaining to this subject,
  between the Company and the Employee, whether written or oral.  The
  parties further agree that no modifications of this Agreement may be made
  except by means of a written agreement or memorandum signed by the
  parties.

  14.  Governing Law.  The parties acknowledge that the Company's principal
  place of business is located in the state of Colorado, and that this
  Agreement has been entered into in the state of Colorado and that they
  wish legal certainty and predictability as to the terms of their
  undertaking.  Accordingly, the parties hereby agree that this agreement
  shall be constructed in accordance with the laws of the state of
  Colorado, without giving consideration to its choice of law provisions.

  15.  Captions.  The captions or section headings used in this Agreement
  are for ease of reference only and shall have no bearing whatsoever upon
  the construction, interpretation and effect of this Agreement.

  16.  Severability.  The Employee believes and acknowledges that the
  provisions contained in this Agreement, including the covenants contained
  in Sections 9, 10 and 11 of this Agreement, are fair and reasonable.
  Nonetheless, in the event that any provision or any part of any provision
  of this Agreement found by a court to be void or unenforceable for any
  reason whatsoever, then such provision shall be stricken, severed from
  this Agreement, and of no force and effect.  Unless such stricken
  provision goes to the essence of the consideration bargained for by a
  party, the remaining provisions of this Agreement shall continue in full
  force and effect, and to the extent required, shall be modified to
  preserve their validity.

  17.  Successors and Assigns.  This Agreement shall be binding upon and
  shall inure to the benefit of the Company and its successors and assigns.
  This Agreement shall be binding upon and shall inure to the benefit of
  the Employee and his personal representatives, but shall not be
  assignable by the Employee.

  18.  Notice.  All notices, requests and other communications hereunder
  shall be in writing and shall be delivered by courier or other means of
  personal service (including by means of a nationally recognized courier
  service or professional messenger service); or sent by facsimile (if a
