4.   EXPENSES.

     Executive shall be entitled to reimbursement for travel and other out-of-
pocket expenses incurred by Executive in the performance of her duties
hereunder, upon submission and approval of written statements and bills in
accordance with the then regular procedures of the Company. Executive shall be
entitled to reasonable vacations in accordance with the then regular procedures
of the Company governing executives.

5.   NONCOMPETITION; NON-SOLICITATION.

     Executive agrees that she will not during the Employment Period engage in,
or otherwise directly or indirectly be employed by, or act as a consultant or
lender to, or be a director, officer, employee, owner or partner of, any other
business or organization that directly or indirectly competes with the business
of the Company or any of its subsidiaries; provided, however, that
notwithstanding the foregoing, the provisions of this Section 5 will not be
deemed breached merely because Executive owns not more than 1 percent of the
outstanding equity securities of an entity, if, at the time of its acquisition
by Executive, such securities are listed on a national securities exchange, is
reported on the Nasdaq Stock Market, or is regularly traded in the over-the-
counter market by a member of a national securities exchange.  Executive agrees
that she shall not, during the two-year period after she voluntarily terminates
this Agreement or is terminated pursuant to this Agreement for "cause" (as
defined in Section 7(d) below), solicit or encourage any employee, consultant,
vendor, supplier or customer of the Company or Canmax to leave the employment
of, or cease or diminish its relations with, the Company or Canmax.

6.   CONFIDENTIAL INFORMATION.

     All confidential information which Executive may now possess, may obtain
from the Company or its subsidiaries during or after the Employment Period, or
may create prior to the end of the Employment Period or otherwise relating to
the financial condition, results of operations, business, properties, assets,
liabilities, or future prospects of the Company or of any customer or supplier
of any of them shall not be published, disclosed, or made accessible by her to
any other person or entity either during or after the termination of her
employment or used by her except during the Employment Period in the business
and for the benefit of the Company and its subsidiaries, in each case without
prior written permission of the Company. Executive shall deliver to the Company
all tangible evidence of such confidential information prior to or at the
termination of her employment. The provisions of this Section 6 shall survive
the termination of this Agreement by either party.

7.   TERMINATION.

     (a)  EXECUTIVE'S DEATH.  If Executive shall die during the Employment
Period, this Agreement shall terminate, except that Executive's estate
("Estate") shall be entitled to receive (i) the base salary payable to
Executive, accrued to the last day of the month in which her death occurs, (ii)
for a period of three (3) months following death, payments equal to fifty
percent (50%) of the payments of Executive's base salary effective at the time
of death, each in 

- -------------------------------------------------------------------------------
EMPLOYMENT CONTRACT - PAGE 3


accordance with the Company's regular payroll cycle, and (iii) any death 
benefits provided under employee benefit plans maintained by the Company. In 
addition, if Executive shall die during the Employment Period and 
notwithstanding any contrary provisions of any Company stock option, warrant 
or stock option plan, the Estate shall have the right to retain and exercise 
(y) any vested options or warrants outstanding on the date of death and (z) 
any unvested options or warrants outstanding on the date of death that vest 
within one year of the date of death, in each case in accordance with their 
respective terms.

     (b)  EXECUTIVE'S DISABILITY.  If, during the Employment Period, Executive
shall become Disabled (as defined below), this Agreement shall terminate
effective on such incapacity, and Executive (or her legal representatives) shall
be entitled only to the base compensation earned through the date of termination
with no entitlement to any base salary after the date of termination; provided,
however, that (i) Executive shall be entitled to receive all benefits to which
she may be entitled pursuant to the Company's employee benefit plans; and (ii)
the Company shall not be obligated to make any payments to Executive under this
Section 7(b) to the extent that such payments, when aggregated with all other
salary or disability payments received by Executive (whether from disability
programs maintained by the Company or otherwise) exceed the then current base
salary of Executive. As used herein, the term "Disabled" or "Disability" shall
mean a mental or physical condition that prevents Executive from performing his
usual duties and services hereunder for a period of six (6) consecutive months
or six (6) non-consecutive months in any twelve (12) month period, as determined
in the reasonable discretion of the Board of Directors of Canmax; provided that
if Executive disputes such determination by the Board of Directors, Executive
(or his legal representatives) shall notify the Board of Directors in writing
and (x) the Board of Directors and Executive (or his legal representatives)
shall each designate a licensed physician practicing in the field to which the
alleged Disability relates within fifteen (15) days of the delivery of such
notice, (y) the designated physicians shall within fifteen (15) days select a
third physician practicing in the field to which the alleged Disability relates,
and (z) the third physician shall determine whether Executive is or has been
Disabled within the meaning of this Agreement.

     (c)  TERMINATION WITHOUT CAUSE.  This Agreement may be terminated by the
Company or Canmax without cause upon thirty (30) days' prior written notice
thereof given to Executive. In the event of termination without cause, the
Company shall (i) for a period of one (1) year continue to pay Executive the
base salary effective at the time of termination in accordance with the
Company's regular payroll cycle and (ii) for a period of six (6) months pay to
Executive a monthly amount equal to one twelfth of any bonuses paid during the
twelve-month period preceding the date of termination. Additionally, Executive
shall be entitled to continue to participate in all regular employee benefit
plans of the Company for a period of one (1) year following termination without
cause; provided, however, that if Executive accepts another job during such
period that provides employee benefits comparable to those offered by the
Company at such time at a cost to Executive no greater than the cost of the
benefits provided by the Company, the Company's obligation to extend such
benefits to Executive shall cease.

- -------------------------------------------------------------------------------
EMPLOYMENT CONTRACT - PAGE 4


     (d)  TERMINATION FOR CAUSE. This Agreement may be terminated by the Company
or Canmax "for cause", as defined below, by delivering to Executive written
notice describing the cause and granting Executive thirty (30) days to respond
to the Chief Executive Officer of the Company or the Board of Directors of
Canmax.  If this Agreement is terminated by the Company for cause, Executive
shall only be entitled to the base salary earned by her to the date of
termination with no entitlement to any base salary continuation payments or
benefits continuation (except as otherwise provided by the terms of any employee
benefit plan of the Company).  The determination as to whether termination is
for cause shall be made by the Chief Executive Officer of the Company or the
Board of Directors of Canmax in the exercise of its business judgment.
Termination of this Agreement by the Company for cause shall be deemed to have
occurred only if:

          (i)  termination shall have been the result of an act or acts of
     dishonesty on the Executive's part constituting a felony or intended to
     result directly or indirectly in substantial gain or personal enrichment to
     her at the expense of the Company; or

          (ii) termination shall have been the result of the Executive's willful
     and continued failure substantially to perform her duties and
     responsibilities as an officer of the Company (other than such failure
     resulting from her incapacity due to physical or mental illness) after a
     demand for substantial performance is delivered to the Executive by the
     Chief Executive Officer of the Company or the Board of Directors of Canmax
     which specifically identifies the manner in which such Board believes that
     the Executive has not substantially performed her duties and the Executive
     is given a reasonable time after such demand substantially to perform her
     duties.

     Executive's employment shall in no event be considered to have been
terminated by the Company for cause if the act or failure to act upon which the
termination is based (A) was done or omitted to be done without intent of
gaining therefrom directly or indirectly a profit to which the Executive was not
legally entitled and as a result of her good faith belief that such act or
failure to act was in or was not opposed to the interests of the Company, or (B)
is an act or failure to act in respect of which the Executive meets the
applicable standard of conduct prescribed for indemnification or reimbursement
of expenses under the Bylaws of the Company or the laws of its state of
incorporation.

     (e)  VOLUNTARY TERMINATION BY EXECUTIVE. Executive may terminate this
Agreement at any time upon delivering thirty (30) days' written notice to the
Company.  In the event of such voluntary termination other than for "good
reason", as hereinafter defined, Executive shall be entitled to her base salary
earned to the date of her resignation, but no base salary continuation payment
or benefits continuation (except as provided by the terms of the Company's
employee benefit plans). On or after the date the Company receives notice of
Executive's resignation (other than resignation for good reason), the Company
may, at its option, pay Executive her base salary through the effective date of
her resignation and terminate her employment immediately.

- -------------------------------------------------------------------------------
EMPLOYMENT CONTRACT - PAGE 5


     (f)  TERMINATION BY EXECUTIVE FOR GOOD REASON. Executive may at any time
voluntarily terminate her employment for "good reason", as defined below, upon
thirty (30) days written notice thereof to the Company; provided that the
Company may, at its option, pay Executive her base salary through the effective
date of her resignation, terminate her employment immediately (except for the
provision of non monetary benefits) and, following the effective date of such
resignation, provide the payments and benefits provided in Section 7(c).  In the
event of such voluntary termination for "good reason", Executive shall be deemed
to have been terminated without cause with the same payments and benefits set
forth in Section 7(c) being applicable to Executive's termination under this
Section 7(f).

     For purposes of this Agreement, "good reason" shall mean the occurrence of
any of the following events:

          (i)  removal from the offices Executive holds on the date of this
     Agreement or a material reduction in Executive's authority or
     responsibility, but not including termination of Executive "for cause";

          (ii) reduction in the base salary payable to Executive; or

          (iii) the Company otherwise commits a material breach of this
     Agreement;

provided that "good reason" shall not include the temporary appointment of
another person to fulfill Executive's responsibilities during any period of
disability of Executive.

8.   CHANGE OF CONTROL

     (a)  CONCERNS REGARDING CHANGE OF CONTROL. Executive and the Company agree
that the circumstances surrounding a "Change of Control," as hereinafter
defined, impose unique risks to the Company and the Executive and that in
response to the unique circumstances surrounding a Change of Control, the
provisions of this Agreement shall separately consider the parties rights' and
obligations in the event that a Change of Control occurs. This Section 8 shall
be applicable whether or not a Change of Control is contemplated at this time. 
Notwithstanding any other provision of this Agreement, the severance payments
and benefits, if any, payable to Executive shall be determined solely by
reference to this Section 8 in the event that a Change of Control has occurred,
or if Executive is "involuntarily terminated," as hereinafter defined, in
contemplation of a Change of Control.

     (b)  VOLUNTARY TERMINATION FOLLOWING A CHANGE OF CONTROL.  If a Change of
Control has occurred, Executive shall have ninety (90) days in which to
terminate her employment. If Executive voluntarily terminates her employment
within ninety (90) days following a Change of Control she shall be entitled to
receive one (1) year's base salary as a lump sum payment.  Upon payment of the
severance compensation described in the preceding sentence, the Company will
have no future obligation to Executive under this Agreement.  Except as
otherwise provided in Section 8(c), if Executive does not voluntarily terminate
her employment within ninety (90) days 

- -------------------------------------------------------------------------------
EMPLOYMENT CONTRACT - PAGE 6



of a Change of Control, Executive shall not be entitled to any severance 
compensation if she voluntarily terminates her employment after that time.

     (c)  INVOLUNTARY TERMINATION IN CONTEMPLATION OF, OR WITHIN TWO YEARS
FOLLOWING, A CHANGE OF CONTROL.  If Executive is involuntarily terminated, other
than "for cause" (as defined in Section 7(d)) in contemplation of, or within two
(2) years following, a Change of Control, the Company shall pay Executive (i) a
lump sum severance payment equal to (A) the Executive's annualized base salary
in effect at the time of involuntary termination plus (B) fifty percent (50%) of
any bonus paid during the preceding twelve-month period, payable as a lump sum,
and (ii) continuation of all employee benefits, executive benefits and
perquisites, or benefits reasonably equivalent thereto, for a period of one (1)
year; provided, however, that if Executive accepts another job during such
period that provides employee benefits comparable to those offered by the
Company at such time at a cost to Executive no greater than the cost of the
benefits provided by the Company, the Company's obligation to extend such
benefits to Executive shall cease.

          For purposes of this Agreement, the following shall be deemed to
constitute involuntary termination:

          (i)  dismissal of Executive (except termination for cause as defined
     in Section 7(d) hereof);

          (ii) reduction in Executive's base salary;

          (iii) reduction in the level of employee benefits received by
     Executive, unless substituted with reasonably comparable benefits;

          (iv) requesting Executive to relocate more than 100 miles from her
     current location other than the relocation of Executive in connection with
     the relocation of the Company's corporate headquarters or relocation to
     another existing facility of the Company;

          (v)  removal from the offices Executive holds on the date of this
     Agreement or a material reduction in Executive's authority or
     responsibility; or

          (vi) the Company otherwise commits a material breach of this
     Agreement.

          In the event that within two (2) years following a Change of Control,
Executive is terminated for cause, Executive shall only be entitled to her base
salary up until the last date of employment pursuant to the date of termination
for cause.

     (d)  TERMINATION OF THIS AGREEMENT MORE THAN TWO YEARS AFTER A CHANGE OF
CONTROL. The parties' rights and obligations arising from a termination of this
Agreement, whether by Executive or the Company, that occurs more than two (2)
years following a Change of Control shall be governed by Section 7 of this
Agreement.

- -------------------------------------------------------------------------------
EMPLOYMENT CONTRACT - PAGE 7


     (e)  DEFINITION OF CHANGE OF CONTROL. For purposes of this Agreement, a
Change of Control shall be deemed to exist upon the occurrence of any of the
following:

          (i)  any "Person" (as such term is used in Section 13(d) and Section
     14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
     Act"), is or becomes a "beneficial owner" (as defined in Section 13d-3
     under the Exchange Act), directly or indirectly, of securities of the
     Company or Canmax representing more than thirty percent (30%) of the
     combined voting power of the outstanding securities of the Company or
     Canmax Inc.;

          (ii) at any time during the twenty-four (24) month period following a
     merger, tender offer, consolidation, sale of assets or contested election,
     or any combination of such transactions, at least a majority of the Board
     of Directors of the Company or Canmax shall cease to be "continuing
     directors" (meaning directors of the Company or Canmax prior to such
     transaction or who subsequently became directors and whose election or
     nomination for election by the stockholders of the Company or Canmax, was
     approved by a vote of at least two-thirds of the directors then still in
     office prior to such transaction);

          (iii) the stockholders approve an agreement of sale or disposition
     by the Company or Canmax of all or substantially all of the assets of the
     Company or Canmax;

provided, however, that no Change of Control shall be deemed to have occurred
for purposes of this Agreement by reason of the anticipated merger of Auto-Gas
Systems, Inc. into the Company or the related issuance of shares of Canmax
common stock.

     (f)  VESTING OF OPTIONS AND WARRANTS.  Upon any Change of Control, any
unvested options or warrants held by Executive to acquire shares of Canmax
common stock shall be immediately vested and exercisable by Executive, and
Canmax undertakes to amend any existing stock option or warrant agreements
between Canmax and/or the Company and Executive consistent with this Section
8(f).

     (g)  NO MITIGATION OF COMPENSATION.  Executive shall not be required to
mitigate any severance payments received under this Section 8 due to her
employment with a successor organization.

9.   SURVIVAL.

     The covenants, agreements, representations, and warranties contained in or
made pursuant to this Agreement shall survive Executive's termination of
employment.

right thereafter to insist upon strict adherence to that term or any other term
of this Agreement. Any waiver must be in writing.
