                        HYDROGEN BURNER TECHNOLOGY, INC.

                             KEY EMPLOYEE AGREEMENT
                                       FOR
                                 DAVID M. MOARD

                                    RECITALS

     A. Whereas, David M. Moard ("Executive") and Hydrogen Burner Technology,
Inc. (the "Company") have previously entered into two employment agreements,
each with a term commencing effective January 1, 1999, the first of which was
executed on behalf of the Company by Leonard Greiner, and the second of which
was entered into on behalf of the Company by Joseph Stell, and was intended to
supersede in its entirety the first employment agreement.

     B. Whereas, the Company is anticipating additional financing, including a
potential public offering of its securities, and has hired additional
executives, and consequently desires to achieve greater uniformity in its
executive employment agreements.

     C. Whereas the Compensation Committee of the Board of Directors, without
the participation of Executive, has approved in principle the terms and
conditions set forth herein for the purpose of wholly superseding any and all
prior employment agreements, and Executive is agreeable to same.

                                    AGREEMENT

     Now, therefore, the Company and Executive hereby, on this 1st day of
August, 2000, agree as follows:

     1.   POSITION AND RESPONSIBILITIES.

          1.1  The Company will employ Executive and Executive shall serve as
President and Chief Executive Officer ("CEO") and perform the duties customarily
associated with such capacity from time to time and at such place or places as
the Company shall reasonably designate or as shall be reasonably appropriate and
necessary in connection with such employment.

          1.2  Subject to Section 4 below, Executive will, to the best of his
ability, devote his full time and best efforts to the performance of his duties
hereunder and the business and affairs of the Company. Executive agrees to serve
as a director and/or officer of the Company if elected by the Stockholders
and/or the Board of Directors, as the case may be, and to perform such executive
duties in his position as CEO as may be assigned to Executive by the Board of
Directors of the Company from time to time. Executive will be assigned such
facilities and support staff as are customarily associated with the position of
CEO in companies of similar nature, stage of development, and size as the
Company. Executive will report to the Board of Directors of the Company and be
responsible for the Company's entire business, including supervision of all
other executives of the Company, establishment of their respective job
descriptions and annual business plans, and the creation and execution of the
Company's strategic business plan.

<PAGE>

          1.3  Executive will duly and faithfully perform and observe any and
all rules and regulations which the Company may now or shall hereafter establish
governing the conduct of its business, except to the extent that such rules and
regulations may be inconsistent with Executive's executive position.

     2.   TERM OF EMPLOYMENT; TERMINATION.

          2.1  The effective date of this Agreement is August 1, 2000.

          2.2  Unless otherwise mutually agreed in writing, this Agreement and
Executive's employment by the Company pursuant to this Agreement shall be
terminated on the earliest of:

               (a)  Executive's death, or any illness, disability or other
incapacity in such a manner that Executive is physically rendered unable
regularly to perform the essential functions of his position for a period in
excess of one hundred twenty (120) consecutive days or more than one hundred
eighty (180) days in any consecutive twelve (12) month period;

               (b)  thirty (30) days after Executive, for any reason, gives
written notice to the Company of his termination;

               (c)  thirty (30) days after the Company, without cause, gives
written notice to Executive of his termination; and

               (d)  immediately upon the occurrence of cause as defined in
Section 2.5, below.

               (e)  three (3) years from the date hereof.

          2.3  The determination regarding whether Executive is physically
unable regularly to perform his duties under subsection 2.2 (a) above shall be
made by the Board of Directors. Executive's inability to be physically present
on the Company's premises shall not constitute a presumption that Executive is
unable to perform such duties.

          2.4  Any notice required to be given pursuant to this Section 2 shall
be given in accordance with the provisions of Section 9 hereof. The exercise of
either party's right to terminate this Agreement pursuant to subsections (b) or
(c) above shall not abrogate the rights and remedies of the terminating party
regarding the breach, if any, giving rise to such termination.

          2.5  For purposes hereof, "cause" shall mean and Executive may be
terminated for cause if, in the reasonable determination of the Company's Board
of Directors, Executive (i) is convicted of any felony or of any crime involving
moral turpitude, (ii) knowingly participates in any fraud against the Company,
(iii) willfully and knowingly breaches or fails to perform his duties to the
Company, (iv) wrongfully and knowingly discloses any trade secrets or other
Confidential Information of the Company (as such term is defined below) in
violation of the Company's Confidentiality Policy, (v) materially and knowingly
breaches Section 4 of this Agreement or any material provision of any stock
option agreement between Executive and the Company ("Option Agreement"), or (vi)
knowingly fails in a material way, to adhere to the policies or procedures of
the Company, including without limitation, as published in the Company's
Employee Manual or written directives of the Board of Directors that reasonably
specify Executive's duties in a manner consistent with Section 1.1, including,
without limitation,

                                       2
<PAGE>

Executive's Job Description and Annual Performance Plan (if any). Actions taken
by Executive pursuant to his reasonable and good faith belief that they are (i)
in the best interests of the Company and (ii) consistent with Executive's
responsibilities as CEO, shall not be a basis for termination by reason of
"cause" for purposes of this Agreement or any Option Agreement, although the
Company retains the right to terminate Executive for any reason or no reason,
without cause, in accordance with Section 2.2(c).

     3.   COMPENSATION:

          3.1  For the period beginning on the effective date of this Agreement
through January 1, 2001, the Company shall pay to Executive for the services to
be rendered hereunder a basic salary at an annual rate of $200,000. Effective
January 1, 2001, if Executive's performance then remains satisfactory in the
reasonable determination of the Company's Board of Directors, the Company shall
pay Executive for the services to be rendered hereunder a basic salary at an
annual rate of $300,000. The amounts paid to Executive as a basic salary are
subject to increase in accordance with the policies of the Company in force from
time to time, with such amounts to be determined by the Company's Board of
Directors on an annual basis. The basic salary shall be payable to Executive in
installments in accordance with Company policy on the same basis as the
Company's other executives are paid. Executive shall also be entitled to all
rights and benefits for which Executive shall be eligible under bonus, pension,
group insurance, long-term disability, life insurance, 401(k) Plan,
profit-sharing or other Company benefits which may be in force from time to time
and provided to the Company's executive management team generally.

          3.2  Beginning with respect to the year 2000, Executive will be
eligible to receive, at the discretion of the Company's Board of Directors, a
performance bonus of up to two hundred percent (200%) of Executive's base salary
for the same year, paid annually after the end of the fiscal year of the
Company, as is consistent with the Company's executive cash bonus plan in place
for senior executives or officers.

          3.3  Executive acknowledges receipt of fully executed Option
Agreements providing, respectively, for the grant of options to purchase (a)
620,000 shares of common stock of the Company at a price of $1.00 per share on a
fully vested basis, (b) 105,000 shares of common stock of the Company at a price
of $5.00 per share subject to vesting over three years, (c) 50,000 shares of
common stock of the Company at a price of $5.50 per share (intended to the
maximum extent permitted by law to qualify as incentive stock options if
Executive meets the applicable holding requirements) and, as a simultaneous
grant, 25,000 shares of common stock at a price of $5.00 per share, such
aggregate grant of 75,000 shares subject to vesting over three years, (d) as of
the effective date of this Agreement, 105,000 shares of common stock of the
Company at a price of $5.00 per share on a fully vested basis, and (e) as of the
effective date of this Agreement, 3,750 shares of common stock of the Company at
a price of $5.50 per share on a fully vested basis, and agrees that such grants,
on the terms and conditions set forth in such Option Agreements, satisfy all
obligations of the Company to grant options to purchase securities of the
Company, or any of its subsidiaries, to Executive with respect to Executive's
employment with the Company or its subsidiaries for the period through and
including the effective date of this Agreement. Subsequent option grants during
the term of this Agreement or any extension thereof shall be on such terms and
conditions as may be determined by the Compensation Committee in its complete
discretion subject to the applicable requirements of the Company's 2000 Stock
Incentive Plan, or any similar successor plan.

                                       3
<PAGE>

          3.4  Executive shall be entitled to vacation and illness days during
the term of this Agreement consistent with the Company's standard practice for
its executive management generally.

          3.5  If the Company terminates Executive's employment as CEO without
cause pursuant to Section 2.2 (c) hereof, and Executive complies with Section 6
hereof, the Company shall continue to pay Executive the current salary
immediately before such termination as provided in Section 3.1 above for a
period of twenty-four (24) months following any such termination.
Notwithstanding the preceding sentence, however, in the event Executive violates
Section 4.1 or 4.2 within such twenty-four-month period, the Company's
obligations under this Section 3.5 shall cease as of the first day of the first
month in which such violation occurs (the "Cessation Date"), and any payments
made to Executive under this Section 3.5 with respect to the period commencing
on the Cessation Date shall be refundable to the Company as of the date paid.

     4.   CONFIDENTIALITY AND NON-COMPETITION.

          4.1  Confidentiality. During the period of Executive's employment
under Section 1.1 and at all times thereafter, Executive shall treat and
safeguard as confidential and secret all Confidential Information, as defined in
Section 4.7, below, received by him at any time. Without the prior written
consent of the Company, except as required by law, Executive shall not disclose
or reveal any Confidential Information to any third party whatsoever or use the
same in any manner except in connection with the businesses of the Company and
its subsidiaries. In the event that Executive is requested or required (by oral
questions, interrogatories, requests for information or documents, subpoena,
civil investigative demand or other process) to disclose (i) any Confidential
Information or (ii) any information relating to the Option Agreement or his
judgment or recommendations concerning the Company or its subsidiaries as
developed from the Confidential Information, Executive shall provide the Company
with prompt written notice of any such request or requirement so that the
Company may seek an appropriate protective order or waive compliance with the
provisions contained herein. If, failing the entry of a protective order or the
receipt of a waiver hereunder, Executive is, in the reasonable opinion of his
counsel, compelled to disclose Confidential Information, Executive shall
disclose only that portion of the Confidential Information which his counsel
advises that he is compelled to disclose and will exercise his best efforts to
obtain assurances that confidential treatment will be accorded such Confidential
Information.

          4.2  Non-Competition. During the period of Executive's employment
under Section 1.1 and for a one-year period thereafter (the "Non-Compete
Period"), Executive shall not, without prior written consent of the Company, do,
directly or indirectly, any of the following:

               (a)  own, manage, control or participate in the ownership,
management, or control of, or be employed or engaged by or otherwise affiliated
or associated with, any other corporation, partnership, proprietorship, firm,
association or other business entity, or otherwise engage in any business which
competes with the business of the Company or any of its subsidiaries (as such
business is conducted during the term of his employment with the Company or its
subsidiaries) in the geographical regions in which such business is conducted;
provided, however, that the ownership of a maximum of one percent of the
outstanding stock of any publicly traded corporation shall not violate this
covenant; or

                                       4
<PAGE>

               (b)  employ, solicit for employment or assist in employing or
soliciting for employment any present, former or future employee, officer or
agent of the Company or any of its subsidiaries.

          4.3  In the event any court of competent jurisdiction should determine
that the covenant of non-competition contained in Section 4.2 is not enforceable
then the Company and Executive hereby agree to petition such court to modify the
foregoing covenant to the extent, but only to the extent, necessary to create a
covenant which is enforceable in the opinion of such court, with the intention
of the parties that the Company shall be afforded the maximum enforceable
covenant of non-competition which may be available under the circumstances and
applicable law.

          4.4  Executive hereby acknowledges that remedies at law for any breach
by him of this Section 4 may be inadequate and that the damages resulting from
any such breach are not readily susceptible to being measured in monetary terms.
Accordingly, Executive acknowledges that should he violate any provisions of
this Section 4, the Company will be entitled to immediate injunctive relief and
may obtain an order restraining any threatened or future breach by him.
Executive further agrees, subject to the proviso at the end of this sentence,
that if he violates any provision of this Section 4, he shall, in addition to
the effect of the last sentence of Section 3.5, immediately forfeit any then
unpaid rights and benefits under this Agreement not protected under ERISA or
other applicable law, provided that he shall not forfeit any vested but
unexercised options. Nothing in this Section 4.4 will be deemed to limit, in any
way, the other remedies at law or in equity of the Company, for the breach by
Executive of any of the provisions of this Section 4.

          4.5  Executive hereby agrees to provide written notice of the
provisions of this Section 4 to any future employer that proposes to employ him,
and the Company expressly reserves the right to provide such notice to such
employer(s).

          4.6  If any provision or part of any provision of this Section 4 is
held for any reason to be unenforceable, (i) the remainder of this Section 4
shall nevertheless remain in full force and effect and (ii) such provision or
part shall be deemed to be amended in such manner as to render such provision
enforceable.

          4.7  For purposes of this Agreement, "Confidential Information" means
any information not generally known to the public, including, without limiting
the generality of the foregoing, any customer lists, supplier lists, trade
secrets, invention, formulas, methods or processes, whether or not patented or
patentable, channels of distribution, business plans, pricing policies and
records, financial information of any sort and inventory records of the Company
or any affiliate (and such other information normally understood to be
confidential or otherwise designated as such in writing by the Company or its
subsidiaries). It is not necessary, however, that any information be formally
designated as "confidential" if it falls within any of the foregoing categories
and is not generally known to the public. However, following the delivery to
Executive of the Company's Confidentiality Policy, information shall not be
deemed Confidential Information if it does not fall into a category specified in
such Confidentiality Policy or if it is revealed by Executive in a manner which
does not violate the rules for control of Confidential Information established
by such Confidentiality Policy.

          4.8  Executive shall, for a period of two (2) years after his
termination of employment, notify the Company of any change of address and each
subsequent employment (stating the name and address of the employer and the
nature of Executive's position) or business activity in which he engages during
such two (2) years.

                                       5
<PAGE>

     5.   FORMER EMPLOYMENT.

          5.1  Executive represents and warrants that his employment by the
Company will not conflict with and will not be constrained by any prior
employment or consulting agreement or relationship. Executive represents and
warrants that Executive does not possess confidential information arising out of
prior employment which, in his best judgment, would be utilized in connection
with his employment by the Company, except in accordance with agreements between
his former employer and the Company.

          5.2  If, in spite of the second sentence of Section 5.1, Executive
should find that confidential information belonging to any former employer might
be usable in connection with the Company's business, Executive will not
intentionally disclose to the Company or use on behalf of the Company any
confidential information belonging to any of his former employers (except in
accordance with agreements between the Company and any such former employer);
but during Executive's employment by the Company he will use in the performance
of his duties information which is generally known and used by persons with
training and experience comparable to his own and information which is common
knowledge in the industry or otherwise legally in the public domain.

     6.   RELEASE AND POST-EMPLOYMENT CONSULTATION.

          6.1  The payment under Section 3.5 shall be made only upon the
condition that Executive shall have executed a release of any and all employment
related claims arising out of this Agreement in substantially the form set forth
as Exhibit B hereto.

          6.2  In the event Executive is entitled to payments under Section 3.5,
then during any month in which he is entitled to such payments and in which he
is not employed in a full-time position, he shall, upon thirty days written
notice (which may be waived by the parties) perform consulting tasks on behalf
of the Company for up to sixteen (16) hours per month. However, in the event
Executive does not reside in Los Angeles or Orange County, California or does so
reside, but is traveling, such consulting may occur by telephone with the
Company bearing the cost of the calls.

     7.   ASSIGNMENT. Neither this Agreement nor any rights or obligations
hereunder may be assigned by Executive or the Company.

     8.   SEVERABILITY. In case any one or more of the provisions contained in
this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.

     9.   NOTICES. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon the earliest of personal
delivery, receipt or the third full day following deposit in the United States
Post Office with postage and fees prepaid, addressed to the other party hereto
at the address hereinafter shown below such party's signature or at such other
address as such party may designate by ten (10) days' advance written notice to
the other party hereto.

     10.  RETURN OF COMPANY DOCUMENTS. Executive shall, at the time of leaving
the employ of the Company, deliver to the Company (and will not keep in his
possession, recreate or deliver to anyone else) any and all devices, records,
data, notes, reports, proposals, lists, correspondence, specifications,
drawings, blueprints, sketches, materials, equipment, other documents or
property, or reproductions of any aforementioned items

                                       6
<PAGE>

developed by him pursuant to his employment with the Company or otherwise
belonging to the company, its successors or assigns.

     11.  ARBITRATION. Except as provided in Section 4.4 above, Executive and
the Company hereby agree that any dispute or controversy arising out or relating
to any interpretation, construction, performance or breach of this Agreement or
the Option Agreement, shall be settled by arbitration to be held in the City of
Long Beach and County of Los Angeles, California, in accordance with the rules
then in effect of the American Arbitration Association. The arbitrator may grant
injunctions or other relief in such dispute or controversy, in addition to other
remedies permitted by law in the case of the claim involved. The decision of the
arbitrator shall be final, conclusive and binding upon the parties to the
arbitration. Judgment may be entered on the arbitrator's decision in any court
having jurisdiction. The Company shall advance the costs and expenses of such
arbitration, and each party shall separately pay any of his or its counsel fees
and expenses, provided that the arbitrator shall have the power to award either
side reasonable attorney fees and costs or arbitration costs and expenses based
upon the law pertaining to the claim were it litigated in a court of law and the
merits of the case.

     12.  APPLICABLE LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of California, as such laws are applied
to contracts entered into and performed in such state.

     13.  WAIVER. If either party should waive any breach of any provisions of
this Agreement, he or it shall not thereby be deemed to have waived any
preceding or succeeding breach of the same or any other provision of this
Agreement.

     14.  COMPLETE AGREEMENT; AMENDMENTS. The foregoing, together with each
Option Agreement and Exhibit B, is the entire agreement of the parties with
respect to the subject matter hereof and thereof and may not be amended,
supplemented, canceled or discharged except by written instrument executed by
both parties hereto. This Agreement supersedes any and all prior agreements
between the parties pertaining to the employment of Executive, and the parties
agree that as of the effective date of this Agreement there are no obligations
of either party arising out of any prior agreements or the employment of the
Executive, except as set forth in this Agreement.

     15.  HEADINGS. The headings of the sections hereof are inserted for
convenience only and shall not be deemed to constitute a part hereof nor to
affect the meaning thereof.

                                       7
<PAGE>

     16.  ATTORNEY FEES. If either party hereto brings any action to enforce its
rights hereunder, the prevailing party in any such action shall be entitled to
recover his or its reasonable attorneys' fees and costs incurred in connection
with such action.

                               EXHIBIT B: RELEASE

     I, DAVID M. MOARD, in consideration of and as a precondition to the
agreement by Hydrogen Burner Technology, Inc., a California corporation
(hereinafter, "Company") to continue to pay my current monthly salary
(subject to all applicable state and federal withholdings amounts) for a
period of twenty-four (24) months beginning with the first month following my
last day of employment with the Company, for and on behalf of myself, my
agents, heirs, executors, administrators, and assigns, do hereby release and
forever discharge Company and all of its successors and assigns, and all of
its and their respective agents, directors, officers, partners, employees,
representatives, insurers, attorneys, and joint venturers, and each of them
(hereinafter, "Released Parties"), from any and all claims which are based
upon acts or events that occurred on or before the date on which this
Agreement becomes enforceable, including any claim arising under any state or
federal statute or common law, including, but not limited to, Title VII of
the Civil Rights Act of 1964, 42 U.S.C. Section 2000e ("Title VII"), the
Americans with Disabilities Act, 42 U.S.C. Section 12101, et seq. ("ADA"),
the Age Discrimination in Employment Act, 29 U.S.C. Section 623 ("ADEA"), the
Worker Adjustment and Retraining Notification Act, 29 U.S.C. Section 2101, et
seq. ("WARN"), and the California Fair Employment and Housing Act, Cal. Gov't
Code Section 12940, et seq. The phrase "any and all claims" shall be
interpreted liberally to preclude any further disputes, litigation, or
controversies between myself and any of the Released Parties based upon
events that occurred on or before the effective date of this Agreement.

     I am familiar with Section 1542 of the California Civil Code, which reads
as follows:

     A general release does not extend to claims which the creditor does not
     know or suspect to exist in his favor at the time of executing the release,
     which if known by him must have materially affected his settlement with the
     debtor.

I am releasing unknown claims and waive all rights I have or may have under
Civil Code Section 1542 or under any other statute or common law principle of
similar effect. However, I am not waiving any rights or claims that may arise
out of acts or events that occur after the date on which I sign this Release.

     I have been given 21 days to consider whether or not to sign this Release
and have been advised in writing to consult with an attorney prior to signing
it. I understand that I may revoke this agreement at any time on or before the
date which is seven (7) calendar days after the date of my signature on this
Release and that, unless previously revoked, the Release will be effective and
enforceable upon the expiration of the seven-day revocation period.

                                       9

     I have read this Release and understand all of its terms. I execute it
voluntarily and with full knowledge of its significance.

   Signed at _______________, ____________, this ___ day of ____________, 200_.

                                    RECITALS

     A. Whereas, Larry Frost ("Executive") and Hydrogen Burner Technology, Inc.
(the "Company") have previously entered into an employment agreement, with a
term commencing effective January 1, 1999.

     B. Whereas, the Company is anticipating additional financing, including a
potential public offering of its securities, and has hired additional
executives, and consequently desires to achieve greater uniformity in its
executive employment agreements.

     C. Whereas the Compensation Committee of the Board of Directors, has
approved in principle the terms and conditions set forth herein for the purpose
of wholly superseding any and all prior employment agreements, and Executive is
agreeable to same.

                                    AGREEMENT

     Now, therefore, the Company and Executive hereby, on this 1st day of
August, 2000, agree as follows:

     1.   POSITION AND RESPONSIBILITIES.

          1.1  The Company will employ Executive and Executive shall serve as
Treasurer/Controller and Assistant Secretary ("Controller") and perform the
duties customarily associated with such capacity from time to time and at such
place or places as the Company shall reasonably designate or as shall be
reasonably appropriate and necessary in connection with such employment.

          1.2  Subject to Section 4 below, Executive will, to the best of his
ability, devote his full time and best efforts to the performance of his duties
hereunder and the business and affairs of the Company. Executive agrees to serve
as a director and/or officer of the Company if elected by the Stockholders
and/or the Board of Directors, as the case may be, and to perform such executive
duties in his position as Controller as may be assigned to Executive by the
Chief Executive Officer of the Company (the "CEO") from time to time, in
particular as set forth in Executive's Job Description and Annual Performance
Plan. Executive will be assigned such facilities and support staff as are
customarily associated with the position of Controller in companies of similar
nature, stage of development, and size as the Company. Executive will report to
the Chief Financial Officer of the Company.

          1.3  Executive will duly and faithfully perform and observe any and
all rules and regulations which the Company may now or shall hereafter establish
governing the conduct of its business, except to the extent that such rules and
regulations may be inconsistent with Executive's executive position.

     2.   TERM OF EMPLOYMENT; TERMINATION.

          2.1  The effective date of this Agreement is August 1, 2000.

          2.2  Unless otherwise mutually agreed in writing, this Agreement and
Executive's employment by the Company pursuant to this Agreement shall be
terminated on the earliest of:

               (a)  Executive's death, or any illness, disability or other
incapacity in such a manner that Executive is physically rendered unable
regularly to perform the functions of his position as described in Executive's
Job Description and Annual Performance Plan for a period in excess of one
hundred twenty (120) consecutive days or more than one hundred eighty (180) days
in any consecutive twelve (12) month period;

               (b)  thirty (30) days after Executive, for any reason, gives
written notice to the Company of his termination;

               (c)  thirty (30) days after the Company, without cause, gives
written notice to Executive of his termination; and

               (d)  immediately upon the occurrence of cause as defined in
Section 2.5, below.

               (e)  three (3) years from the date hereof.

          2.3  The determination regarding whether Executive is physically
unable regularly to perform his duties under subsection 2.2 (a) above shall be
made by the Board of Directors. Executive's inability to be physically present
on the Company's premises shall not constitute a presumption that Executive is
unable to perform such duties.

          2.4  Any notice required to be given pursuant to this Section 2 shall
be given in accordance with the provisions of Section 9 hereof. The exercise of
either party's right to terminate this Agreement pursuant to subsections (b) or
(c) above shall not abrogate the rights and remedies of the terminating party
regarding the breach, if any, giving rise to such termination.

          2.5  For purposes hereof, "cause" shall mean and Executive may be
terminated for cause if, in the reasonable determination of the Company's Board
of Directors, Executive (i) is convicted of any felony or of any crime involving
moral turpitude, (ii) knowingly participates in any fraud against the Company,
(iii) willfully and knowingly breaches or fails to perform his duties to the
Company, (iv) wrongfully and knowingly discloses any trade secrets or other
Confidential Information of the Company (as such term is defined below) in
violation of the Company's Confidentiality Policy, (v) materially and knowingly
breaches Section 4 of this Agreement or any material provision of any stock
option agreement between Executive and the Company ("Option Agreement"), or (vi)
knowingly fails in a material way, to adhere to the policies or procedures of
the Company, including without limitation, as published in the Company's
Employee Manual or written directives of the CEO or CFO that reasonably specify
Executive's duties in a manner consistent with Section 1.1, including, without
limitation, Executive's Job Description and Annual Performance Plan. Actions
taken by Executive pursuant to his reasonable and good faith belief that they
are (i) in the best interests of the Company and (ii) consistent with
Executive's Job Description and Annual Performance Plan, shall not be a basis
for termination by reason of "cause" for purposes of this

                                       2
<PAGE>

Agreement or any Option Agreement, although the Company retains the right to
terminate Executive for any reason or no reason, without cause, in accordance
with Section 2.2(c).

     3.   COMPENSATION:

          3.1  For the period beginning on the effective date of this Agreement
through January 1, 2001, the Company shall pay to Executive for the services to
be rendered hereunder a basic salary at an annual rate of $131,250. Effective
January 1, 2001, if Executive's performance then remains satisfactory in the
reasonable determination of the Company's Board of Directors, the Company shall
pay Executive for the services to be rendered hereunder a basic salary at an
annual rate of $150,000 The amounts paid to Executive as a basic salary are
subject to increase in accordance with the policies of the Company in force from
time to time, with such amounts to be determined by the Company's Board of
Directors on an annual basis. The basic salary shall be payable to Executive in
installments in accordance with Company policy on the same basis as the
Company's other executives are paid. Executive shall also be entitled to all
rights and benefits for which Executive shall be eligible under bonus, pension,
group insurance, long-term disability, life insurance, 401(k) Plan,
profit-sharing or other Company benefits which may be in force from time to time
and provided to the Company's executive management team generally.

          3.2  Beginning with respect to the year 2000, Executive will be
eligible to receive, at the discretion of the Company's Board of Directors, a
performance bonus of up to one hundred-sixty percent(160%) of Executive's base
salary for the same year, paid annually after the end of the fiscal year of the
Company, as is consistent with the Company's executive cash bonus plan in place
for senior executives or officers.

          3.3  Executive acknowledges receipt of fully executed Option
Agreements providing, respectively, for the grant of options to purchase (a)
197,500 shares of common stock of the Company at a price of $1.00 per share on a
fully vested basis, (b) 70,000 shares of common stock of the Company at a price
of $5.00 per share subject to vesting over three years, (c) 50,000 shares of
common stock of the Company at a price of $5.00 per share (intended to the
maximum extent permitted by law to qualify as incentive stock options if
Executive meets the applicable holding requirements) subject to vesting over
three years, and, (d) as of the effective date of this Agreement, 70,000 shares
of common stock of the Company at a price of $5.00 per share on a fully vested
basis, and agrees that such grants, on the terms and conditions set forth in
such Option Agreements, satisfy all obligations of the Company to grant options
to purchase securities of the Company, or any of its subsidiaries, to Executive
with respect to Executive's employment with the Company or its subsidiaries for
the period through and including the effective date of this Agreement.
Subsequent option grants during the term of this Agreement or any extension
thereof shall be on such terms and conditions as may be determined by the
Compensation Committee in its complete discretion subject to the applicable
requirements of the Company's 2000 Stock Incentive Plan, or any similar
successor plan

          3.4  Executive shall be entitled to vacation and illness days during
the term of this Agreement consistent with the Company's standard practice for
its executive management generally, provided, however that his paid time off
shall not be less than that specified in his "Job Offer" memorandum dated
12/2/95 and signed by David Moard.

          3.5  If the Company terminates Executive's employment without cause
pursuant to Section 2.2 (c) hereof, and Executive complies with Section 6
hereof, the Company shall continue to pay Executive the current salary
immediately before such termination as provided in Section 3.1 above for a
period of twelve (12) months following

                                       3
<PAGE>

any such termination. Notwithstanding the preceding sentence, however, in the
event Executive violates Section 4.1 or 4.2 within such twelve-month period, the
Company's obligations under this Section 3.5 shall cease as of the first day of
the first month in which such violation occurs (the "Cessation Date"), and any
payments made to Executive under this Section 3.5 with respect to the period
commencing on the Cessation Date shall be refundable to the Company as of the
date paid.

     4.   CONFIDENTIALITY AND NON-COMPETITION.

          4.1  Confidentiality. During the period of Executive's employment
under Section 1.1 and at all times thereafter, Executive shall treat and
safeguard as confidential and secret all Confidential Information, as defined in
Section 4.7, below, received by him at any time. Without the prior written
consent of the Company, except as required by law, Executive shall not disclose
or reveal any Confidential Information to any third party whatsoever or use the
same in any manner except in connection with the businesses of the Company and
its subsidiaries. In the event that Executive is requested or required (by oral
questions, interrogatories, requests for information or documents, subpoena,
civil investigative demand or other process) to disclose (i) any Confidential
Information or (ii) any information relating to the Option Agreement or his
judgment or recommendations concerning the Company or its subsidiaries as
developed from the Confidential Information, Executive shall provide the Company
with prompt written notice of any such request or requirement so that the
Company may seek an appropriate protective order or waive compliance with the
provisions contained herein. If, failing the entry of a protective order or the
receipt of a waiver hereunder, Executive is, in the reasonable opinion of his
counsel, compelled to disclose Confidential Information, Executive shall
disclose only that portion of the Confidential Information which his counsel
advises that he is compelled to disclose and will exercise his best efforts to
obtain assurances that confidential treatment will be accorded such Confidential
Information.

          4.2  Non-Competition. During the period of Executive's employment
under Section 1.1 and for a one-year period thereafter (the "Non-Compete
Period"), Executive shall not, without prior written consent of the Company, do,
directly or indirectly, any of the following:

               (a)  own, manage, control or participate in the ownership,
management, or control of, or be employed or engaged by or otherwise affiliated
or associated with, any other corporation, partnership, proprietorship, firm,
association or other business entity, or otherwise engage in any business which
competes with the business of the Company or any of its subsidiaries (as such
business is conducted during the term of his employment with the Company or its
subsidiaries) in the geographical regions in which such business is conducted;
provided, however, that the ownership of a maximum of one percent of the
outstanding stock of any publicly traded corporation shall not violate this
covenant; or

               (b)  employ, solicit for employment or assist in employing or
soliciting for employment any present, former or future employee, officer or
agent of the Company or any of its subsidiaries.

          4.3  In the event any court of competent jurisdiction should determine
that the covenant of non-competition contained in Section 4.2 is not enforceable
then the Company and Executive hereby agree to petition such court to modify the
foregoing covenant to the extent, but only to the extent, necessary to create a
covenant which is enforceable in the opinion of such court, with the intention
of the parties that the Company

                                       4
<PAGE>

shall be afforded the maximum enforceable covenant of non-competition which may
be available under the circumstances and applicable law.

          4.4  Executive hereby acknowledges that remedies at law for any
breach by him of this Section 4 may be inadequate and that the damages
resulting from any such breach are not readily susceptible to being measured
in monetary terms. Accordingly, Executive acknowledges that should he violate
any provisions of this Section 4, the Company will be entitled to immediate
injunctive relief and may obtain an order restraining any threatened or
future breach by him. Executive further agrees, subject to the proviso at the
end of this sentence, that if he violates any provision of this Section 4, he
shall, in addition to the effect of the last sentence of Section 3.5,
immediately forfeit any then unpaid rights and benefits under this Agreement
not protected under ERISA or other applicable law, provided that he shall not
forfeit any vested but unexercised options. Nothing in this Section 4.4 will
be deemed to limit, in any way, the other remedies at law or in equity of the
Company, for the breach by Executive of any of the provisions of this Section
4.

          4.5  Executive hereby agrees to provide written notice of the
provisions of this Section 4 to any future employer that proposes to employ him,
and the Company expressly reserves the right to provide such notice to such
employer(s).

          4.6  If any provision or part of any provision of this Section 4 is
held for any reason to be unenforceable, (i) the remainder of this Section 4
shall nevertheless remain in full force and effect and (ii) such provision or
part shall be deemed to be amended in such manner as to render such provision
enforceable.

          4.7  For purposes of this Agreement, "Confidential Information" means
any information not generally known to the public, including, without limiting
the generality of the foregoing, any customer lists, supplier lists, trade
secrets, invention, formulas, methods or processes, whether or not patented or
patentable, channels of distribution, business plans, pricing policies and
records, financial information of any sort and inventory records of the Company
or any affiliate (and such other information normally understood to be
confidential or otherwise designated as such in writing by the Company or its
subsidiaries). It is not necessary, however, that any information be formally
designated as "confidential" if it falls within any of the foregoing categories
and is not generally known to the public. However, following the delivery to
Executive of the Company's Confidentiality Policy, information shall not be
deemed Confidential Information if it does not fall into a category specified in
such Confidentiality Policy or if it is revealed by Executive in a manner which
does not violate the rules for control of Confidential Information established
by such Confidentiality Policy.

          4.8  Executive shall, for a period of two (2) years after his
termination of employment, notify the Company of any change of address and each
subsequent employment (stating the name and address of the employer and the
nature of Executive's position) or business activity in which he engages during
such two (2) years.

     5.   FORMER EMPLOYMENT.

          5.1  Executive represents and warrants that his employment by the
Company will not conflict with and will not be constrained by any prior
employment or consulting agreement or relationship. Executive represents and
warrants that Executive does not possess confidential information arising out of
prior employment which, in his best judgment, would be utilized in connection
with his employment by the Company, except in accordance with agreements between
his former employer and the Company.

                                       5
<PAGE>

          5.2  If, in spite of the second sentence of Section 5.1, Executive
should find that confidential information belonging to any former employer might
be usable in connection with the Company's business, Executive will not
intentionally disclose to the Company or use on behalf of the Company any
confidential information belonging to any of his former employers (except in
accordance with agreements between the Company and any such former employer);
but during Executive's employment by the Company he will use in the performance
of his duties information which is generally known and used by persons with
training and experience comparable to his own and information which is common
knowledge in the industry or otherwise legally in the public domain.

     6.   RELEASE AND POST-EMPLOYMENT CONSULTATION.

          6.1  The payment under Section 3.5 shall be made only upon the
condition that Executive shall have executed a release of any and all employment
related claims arising out of this Agreement in substantially the form set forth
as Exhibit B hereto.

          6.2  In the event Executive is entitled to payments under Section 3.5,
then during any month in which he is entitled to such payments and in which he
is not employed in a full-time position, he shall, upon thirty days written
notice (which may be waived by the parties) perform consulting tasks on behalf
of the Company for up to sixteen (16) hours per month. . However, in the event
Executive does not reside in Los Angeles or Orange County, California or does so
reside, but is traveling, such consulting may occur by telephone with the
Company bearing the cost of the calls.

     7.   ASSIGNMENT. Neither this Agreement nor any rights or obligations
hereunder may be assigned by Executive or the Company.

     8.   SEVERABILITY. In case any one or more of the provisions contained in
this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect the other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein.

     9.   NOTICES. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon the earliest of personal
delivery, receipt or the third full day following deposit in the United States
Post Office with postage and fees prepaid, addressed to the other party hereto
at the address hereinafter shown below such party's signature or at such other
address as such party may designate by ten (10) days' advance written notice to
the other party hereto.

     10.  RETURN OF COMPANY DOCUMENTS. Executive shall, at the time of leaving
the employ of the Company, deliver to the Company (and will not keep in his
possession, recreate or deliver to anyone else) any and all devices, records,
data, notes, reports, proposals, lists, correspondence, specifications,
drawings, blueprints, sketches, materials, equipment, other documents or
property, or reproductions of any aforementioned items developed by him pursuant
to his employment with the Company or otherwise belonging to the company, its
successors or assigns.

     11.  ARBITRATION. Except as provided in Section 4.4 above, Executive and
the Company hereby agree that any dispute or controversy arising out or relating
to any interpretation, construction, performance or breach of this Agreement or
the Option Agreement, shall be settled by arbitration to be held in the City of
Long Beach and County of Los Angeles, California, in accordance with the rules
then in effect of the American Arbitration Association. The arbitrator may grant
injunctions or other relief in such

                                       6
<PAGE>

dispute or controversy, in addition to other remedies permitted by law in the
case of the claim involved. The decision of the arbitrator shall be final,
conclusive and binding upon the parties to the arbitration. Judgment may be
entered on the arbitrator's decision in any court having jurisdiction. The
Company shall advance the costs and expenses of such arbitration, and each party
shall separately pay any of his or its counsel fees and expenses, provided that
the arbitrator shall have the power to award either side reasonable attorney
fees and costs or arbitration costs and expenses based upon the law pertaining
to the claim were it litigated in a court of law and the merits of the case.

     12.  APPLICABLE LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of California, as such laws are applied
to contracts entered into and performed in such state.

     13.  WAIVER. If either party should waive any breach of any provisions of
this Agreement, he or it shall not thereby be deemed to have waived any
preceding or succeeding breach of the same or any other provision of this
Agreement.

     14.  COMPLETE AGREEMENT; AMENDMENTS. The foregoing, together with each
Option Agreement and Exhibit B, is the entire agreement of the parties with
respect to the subject matter hereof and thereof and may not be amended,
supplemented, canceled or discharged except by written instrument executed by
both parties hereto. This Agreement supersedes any and all prior agreements
between the parties pertaining to the employment of Executive, and the parties
agree that as of the effective date of this Agreement there are no obligations
of either party arising out of any prior agreements or the employment of the
Executive, except as set forth in this Agreement.

     15.  HEADINGS. The headings of the sections hereof are inserted for
convenience only and shall not be deemed to constitute a part hereof nor to
affect the meaning thereof.

                                       7

     16.  ATTORNEY FEES. If either party hereto brings any action to enforce its
rights hereunder, the prevailing party in any such action shall be entitled to
recover his or its reasonable attorneys' fees and costs incurred in connection
with such action.

                               EXHIBIT B: RELEASE

     I, LARRY FROST, in consideration of and as a precondition to the
agreement by Hydrogen Burner Technology, Inc., a California corporation
(hereinafter, "Company") to continue to pay my current monthly salary
(subject to all applicable state and federal withholdings amounts) for a
period of twelve months beginning with the first month following my last day
of employment with the Company, for and on behalf of myself, my agents,
heirs, executors, administrators, and assigns, do hereby release and forever
discharge Company and all of its successors and assigns, and all of its and
their respective agents, directors, officers, partners, employees,
representatives, insurers, attorneys, and joint venturers, and each of them
(hereinafter, "Released Parties"), from any and all claims which are based
upon acts or events that occurred on or before the date on which this
Agreement becomes enforceable, including any claim arising under any state or
federal statute or common law, including, but not limited to, Title VII of
the Civil Rights Act of 1964, 42 U.S.C. Section 2000e ("Title VII"), the
Americans with Disabilities Act, 42 U.S.C. Section 12101, ET SEQ. ("ADA"),
the Age Discrimination in Employment Act, 29 U.S.C. Section 623 ("ADEA"), the
Worker Adjustment and Retraining Notification Act, 29 U.S.C. Section 2101, ET
SEQ. ("WARN"), and the California Fair Employment and Housing Act, Cal. Gov't
Code Section 12940, ET SEQ. The phrase "any and all claims" shall be
interpreted liberally to preclude any further disputes, litigation, or
controversies between myself and any of the Released Parties based upon
events that occurred on or before the effective date of this Agreement.

     I am familiar with Section 1542 of the California Civil Code, which reads
as follows:

     A general release does not extend to claims which the creditor does not
     know or suspect to exist in his favor at the time of executing the release,
     which if known by him must have materially affected his settlement with the
     debtor.

I am releasing unknown claims and waive all rights I have or may have under
Civil Code Section 1542 or under any other statute or common law principle of
similar effect. However, I am not waiving any rights or claims that may arise
out of acts or events that occur after the date on which I sign this Release.

     I have been given 21 days to consider whether or not to sign this Release
and have been advised in writing to consult with an attorney prior to signing
it. I understand that I may revoke this agreement at any time on or before the
date which is seven (7) calendar days after the date of my signature on this
Release and that, unless previously revoked, the Release will be effective and
enforceable upon the expiration of the seven-day revocation period.

                                       9
<PAGE>

     I have read this Release and understand all of its terms. I execute it
voluntarily and with full knowledge of its significance.

  Signed at _______________, ____________, this ___ day of ____________, 200_.
