     WHEREAS, the Company desires to establish its right to the services of the
Executive, in the capacity described below, on the terms and conditions set
forth, and the Executive is to accept such employment on such terms and
conditions; and

     WHEREAS, the Company desires to insure, insofar as possible, that it will
continue to have the benefit of the Executive's services over the employment
term and to protect its confidential information and goodwill; and

     NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements hereinafter set forth, the parties hereto mutually
covenant and agree as follows:

                                  SECTION ONE

     1.1 Employment as Executive Vice President of the Company. The Company does
hereby employ, engage and hire the Executive as an Executive Vice President and
Chief Development Officer, or such position of comparable responsibility,
authority and status as appointed from time to time, and the Executive does
hereby accept and agree to such hiring, engagement and employment. The
Executive's duties during the employment period shall be such executive and
managerial duties as are set forth hereunder, as the President of the Company
shall from time to time prescribe. The services which are to be performed by the
Executive hereunder are to be rendered at an employment location which is not
more than twenty-five (25) miles from the Executive's employment location on the
date of the Change of Control, or in such other place or places as shall be
mutually agreed upon in writing by the Executive and the Company from time to

Company, subject to reasonable vacations and absences due to illness.
Furthermore, the Executive will exercise due diligence and care in the
performance of his duties for the Company under this Agreement.

                                  SECTION TWO

     2.1 Employment Term.

     (a) The Executive shall be employed by the Company for the duties as set
forth in Section 1 for the two (2) year period commencing October 13, 2000, and
ending on October 13, 2002, (the "Employment Term"), unless the employment of
the
<PAGE>
Executive is extended pursuant to subparagraph (b) below or terminates earlier
in accordance with the provisions of this Agreement.

     (b) This Agreement will automatically renew for an additional two (2) year
period on the terms and conditions then existing, unless either party notifies
the other in writing of its decision not to renew the Agreement no less than one
(1) year prior to the end of the Employment Term; provided that in no event
shall the Employment Term exceed two (2) years from the date either party
notifies the other of its decision not to renew the Agreement. To the degree
this Agreement is in effect in any renewal of the Employment Term, the total
period under which the Executive renders services shall be referred to as the
"Employment Term."

     (c) Notwithstanding the foregoing, if a Change of Control (as defined in
Section 5.2(g)) occurs when the Executive is employed by the Company, the
Company will continue thereafter to employ the Executive, and the Executive will
remain in the employ of the Company, in accordance with the terms and provisions
of this Agreement, during the Employment Period (as defined in Section 5.2(j)).

                                 SECTION THREE

     3.1 Compensation.

     (a) The Company shall pay the Executive and the Executive agrees to accept

installments or at such other time or times as the Executive and the Company
shall agree and as otherwise provided by law.

     (b) During the Employment Term, the President shall consider and appraise
periodically, but not less frequently than annually, the Executive's
compensation. In determining such compensation, the President shall consider the
commensurate increases given to other corporate officers and key employees
generally both in the Company and in other similarly situated companies, the
scope and success of the Company's operations, the expansion of Executive's
duties and the Executive's performance of his duties.

     3.2 Bonus. The Executive shall also receive such bonuses as may be declared
from time to time by the Company in its sole and absolute discretion.

     3.3 Fringe Benefits. The Executive shall be entitled to the following

benefit plans and employee welfare benefit plans (as such terms are defined in
Sections 3(2) and 3(1), respectively, of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA")) as are sponsored by the Company and generally
available to salaried employee participation. Such participation shall be in
accordance

                                       2

     4.1 Death or Disability. If the Executive becomes physically or mentally
disabled while employed by the Company, and as a result thereof becomes unable
to continue the proper performance of his duties for the Company, or if the
Executive dies while employed by the Company, the Executive's employment shall
automatically cease and terminate. The Company's obligation to pay the
Executive's base salary and bonuses pursuant to Sections 3.1 and 3.2 shall end
as of the date of the Executive's death or, in the case of disability, the
Executive's last day of active employment.

     The Executive shall be considered to be "disabled" for purposes of this
Section 4.1, if, in the judgment of a licensed physician selected by the
Company, the Executive is "disabled" for purposes of the Company's Long Term
Disability Plan.

     4.2 Normal Termination. This Agreement shall automatically renew on the
expiration of the initial Employment Term described in Section 2.1(a) without

Section 4.3, the Company's obligation to pay compensation and benefits pursuant
to SECTION THREE shall continue during the Employment Term.

     4.3 Termination by the Executive. Notwithstanding Section 2.1(b), the
Executive shall have the right to terminate this Agreement at any time. The
Executive agrees to provide the Company with one hundred twenty (120) days prior
written notice of any such termination. The Company's obligation to pay the
Executive's base salary and any bonuses or other compensation pursuant to
SECTION THREE shall cease as of the Executive's last day of work, subject to the
remaining provisions of this Section 4.3. Notwithstanding anything to the
contrary in this Section 4.3, if the Executive gives written notice that the
Company has materially breached any of its commitments under this Agreement,
whether with or without resigning from employment, unless the Company rectifies
the breach within one hundred twenty (120) days of the notice or

                                       3
<PAGE>
disputes the occurrence of the alleged breach in writing within such one hundred
twenty (120) day period, the Company's obligation to pay compensation and
benefits pursuant to SECTION THREE shall continue during the Employment Term
then in effect under Section 2.1(a) or (b), even though the Executive may
thereafter resign. The Company shall be deemed conclusively to have committed
the breach if it does not dispute the occurrence of the alleged breach within
the one hundred twenty (120) day period. If the Executive resigns from the
Company pursuant to such charge of breach and there has been no determination
that the Company did not breach this Agreement, the Executive will be entitled
to receipt of compensation and benefits pursuant to SECTION THREE during the
Employment Term then in effect under Section 2.1(a) or (b). Any determination of
breach pursuant to this Section 4.3 shall be made in accordance with Section
6.1. Compensation and benefits shall remain payable during the period described
in this Section 4.3, provided that if the arbitrator determines that Company has
not materially breached this Agreement, the Executive shall be obligated to
repay to the Company the compensation and benefits paid to the Executive during
such period.

<PAGE>
Date which shall be determined without regard to the Executive's death, subject

during the Employment Period on account of a Disability, the Company may provide
a Notice of Termination, which satisfies the requirements of Section 5.11, and
the Executive's employment shall, for purposes of this Agreement, terminate

participated immediately prior to his or her Disability.

     5.8 Termination Not Giving Rise to a Termination Payment. If, during the

subject to the procedures set forth in Section 5.11, the Executive shall be
entitled to receive only his Accrued Benefits.

     5.9 Termination Giving Rise to a Termination Payment. If, during the
Employment Period, the Executive's employment is terminated by the Executive for
Good Reason or by the Company other than by reason of death or Disability
pursuant to Section 5.7 or for Cause, subject to the procedures set forth in
Section 5.11,

     (a) the Executive shall be entitled to receive, and the Company shall pay,
the Executive's Accrued Benefits and, in lieu of further salary payments for
periods following the Termination Date, as severance pay, a Termination Payment;

<PAGE>
     (b) the Executive and his eligible dependents shall continue to be covered
for two (2) years, under the same terms and conditions, by the medical plan,
dental plan and/or group life insurance plan maintained by the Company which
covered that Executive and his eligible dependents prior to the Executive's
Termination Date. Notwithstanding the foregoing, if the Company's medical plan,
dental plan and/or group life insurance plan covering the Executive on his or
her Termination Date was amended, replaced or terminated on or after the Change
of Control and such action would constitute Good Reason within the meaning of
Section 5.2(k), the Executive and his or her eligible dependents shall be
entitled to continued coverage for purposes of this Section 5.9(b) under the
terms of the medical plan, dental plan and/or group life insurance plan which
they participated in immediately prior to the Change of Control. If the affected
plan is no longer available, the Company shall make arrangements to provide
equivalent coverage to the Executive and his or her eligible dependents. For
this purpose, "equivalent coverage" shall mean medical, dental and/or life
insurance coverage, which, when added to the coverage provided to the Executive
and his or her eligible dependents under the Company's medical plan, dental plan
and/or group life insurance plan in effect on the Executive's Termination Date,
equals or exceeds the level of benefits provided under the medical plan, dental
plan and/or group life insurance plan to the Executive and his or her eligible
dependents on the day immediately preceding the Change of Control. The Executive
and the Company shall share the cost of the continued coverage under this
Section 5.9(b) in the same proportions as the Company and similarly situated
active employees shared the cost of such coverage on the day preceding the
Executive's Termination Date. For purposes of satisfying the Company's or
Employer's obligation under the Consolidated Omnibus Budget Reconciliation Act
("COBRA") to continue group health care coverage to the Executive and his
eligible dependents as a result of the Executive's termination of employment,
the period during which the Executive is permitted to continue to participate in
the Company's medical plans and/or dental plans under this Section 5.9(b) shall
not be taken into account and treated as part of the period during which the
Executive and his eligible dependents are entitled to continued coverage under
the Company's group health plans under COBRA. Following the end of the
continuation period specified in this Section 5.9(b), the Executive and his
eligible dependents shall be covered under such plans and arrangements only as
required under the provisions of COBRA;

     (c) any stock options owned by or granted to the Executive shall be deemed
immediately vested, not forfeitable, and shall be the property of the Executive,
exercisable according to their terms for the balance of the term of years of
such options; and

     (d) "out-placement" services in an amount not to exceed Fifty Thousand
Dollars ($50,000) will be provided by the Company to the Executive for a period
beginning on the Executive's Termination Date. Such services shall be provided
for a period beginning on the Executive's Termination Date and ending on the
earlier of the date on which the Executive becomes employed in a position
commensurate with his or her current salary and responsibilities or the last day
of the twelve (12) month

                                       11
<PAGE>
period which began on the Executive's Termination Date. The "out-placement"
services shall be provided by an out-placement company selected by the Company.

     5.10 Additional Change of Control Payments. In the event of a Change of
Control not approved or endorsed in a resolution by the Incumbent Board, unless
and until the Company adopts and implements an anti-takeover rights plan
approved by a majority of the Incumbent Board, in addition to the compensation
set forth above in Section 5.9:

     (a) all unexercised stock purchase options in the name of the Executive on
the effective date of the Change of Control shall be be deemed fully exercisable
and shall be exercised and paid for by the Company, or the Company's successor
in interest, on behalf of the Executive and the total number of shares of Common
Stock represented by the total number of options shall be fully paid,
nonassessable, and validly issued to the Executive, without payment of monetary
consideration by the Executive. Alternatively, the Executive may elect in lieu
of the receipt of shares, to relinquish his options with respect to all or any
of such shares and receive a payment equal to the price paid for common share in
such merger, tender offer, or similar transaction multiplied by the number of
common shares the Executive could have purchased with the options;

     (b) in connection with the Executive's receipt of the foregoing option
shares or consideration, the Company will pay full tax assistance to keep the
Executive whole due to this immediate income, including payment of all relevant
employment taxes, income taxes, capital gains taxes, and alternative minimum
income taxes, grossed up by an amount necessary to pay all such taxes on the
amounts paid under this subparagraph (b); and

     (c) in the event of a Change of Control of the Company by the exchange of
securities or issuance of stock in a merger or otherwise, the Company and its
successor in interest shall extend to the Executive the opportunity to sell or
exchange the option shares issued under provisions (a) and (b) above in a manner
and at a time that will allow the Executive to benefit, at his election, from
the exchange or issuance of stock in the merger, exchange, or other transaction.

     5.11 Termination Notice and Procedure. Any termination by the Company or
the Executive of the Executive's employment during the Employment Period shall
be communicated by written Notice of Termination to the Executive if such notice
is delivered by the Company and to the Company if such notice is delivered by
the Executive, all in accordance with the following procedures:

     (a) The Notice of Termination shall indicate the specific termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and circumstances alleged to provide a basis for termination.

     (b) Any Notice of Termination by the Company shall be approved by a
resolution duly adopted by a majority of the directors of the Company then in
office.

                                       12
<PAGE>
     (c) If the Company shall give a Notice of Termination for Cause or by
reason of Disability and the Executive in good faith notifies the Company that a
dispute exists concerning such termination within the fifteen (15) day period
following the Executive's receipt of such notice, the Executive may elect to
continue his or her employment during such dispute. If it is thereafter
determined that (i) the reason given by the Company for termination did exist,
the Executive's Termination Date shall be the earlier of (A) the date on which
the dispute is finally determined, either by mutual written agreement of the
parties or pursuant to Section 6.1, (B) the date of the Company's Notice of
Termination for Cause, (C) the date of the Executive's death, or (D) one day
prior to the end of the Employment Period, and the Executive shall not be
entitled to a Termination Payment based on events occurring after the Company
delivered its Notice of Termination; or (ii) the reason given by the Company for
termination did not exist, the employment of the Executive shall continue as if
the Company had not delivered its Notice of Termination and there shall be no
Termination Date arising out of such notice.

     (d) If the Executive shall in good faith give a Notice of Termination for
Good Reason and the Company notifies the Executive that a dispute exists
concerning the termination within the fifteen (15) day period following the
Company's receipt of such notice, the Executive may elect to continue his or her
employment during such dispute. If it is thereafter determined that (i) Good
Reason did exist, the Executive's Termination Date shall be the earlier of (A)
the date on which the dispute is finally determined, either by mutual written
agreement of the parties or pursuant to Section 6.1, (B) the date of the
Executive's death, or (C) one day prior to the end of the Employment Period, and
the Executive's Termination Payment shall reflect events occurring after the
Executive delivered his Notice of Termination; or (ii) Good Reason did not
exist, the employment of the Executive shall continue after such determination
as if the Executive had not delivered the Notice of Termination asserting Good
Reason.

     (e) If the Executive does not elect to continue employment pending
resolution of a dispute regarding a Notice of Termination under Sections 5.10(c)
and (d), and it is finally determined that the reason for termination set forth
in such Notice of Termination did not exist, if such notice was delivered by the
Executive, the Executive will be deemed to have voluntarily terminated his
employment and if delivered by the Company, the Company will be deemed to have
terminated the Executive other than by reason of death, Disability or Cause.

     (f) If the opinion required to be delivered pursuant to Section 5.12(c)
shall not have been delivered on or before the date that would otherwise
constitute the Termination Date, the Termination Date shall be delayed to the
earlier of the date on which such opinion is delivered or one (1) day prior to
the end of the Employment Period.

     5.12 Payment of Termination Benefits.

     (a) Payment of Accrued Benefits shall be made promptly in accordance with
the Company's prevailing practice and the terms of any applicable benefit plans,
contracts or arrangements.

                                       13
<PAGE>
     (b) The Termination Payment shall be payable in a lump sum on the
Executive's Termination Date. Such lump sum payment shall not be reduced by any
present value or similar factor. The Executive shall not be required to mitigate
the amount of such payment by securing other employment or otherwise and such
payment shall not be reduced by reason of the Executive securing other
employment or for any other reason.

     (c) It is the intention of the Company and the Executive that no portion of
the Termination Payment and any other payment under this Agreement, or payments
to or for the benefit of the Executive under any other agreement, plan or
arrangement be deemed to be an "excess parachute payment" as defined in Section
280G of the Code. It is agreed that the present value of the Total Payments
shall not exceed an amount equal to two and ninety-nine hundredths (2.99) times
the Executive's Base Period Income, which is the maximum amount which the
Executive may receive without becoming subject to the tax imposed by Section
4999 of the Code or which the Company may pay without loss of deduction under
Section 280G(a) of the Code. Present value for purposes of this Agreement shall
be calculated in accordance with the regulations issued under Section 280G of
the Code. Within sixty (60) days following delivery of the Notice of Termination
or notice by the Company to the Executive of its belief that there is a payment
or benefit due the Executive which will result in an excess parachute payment as
defined in Section 280G of the Code, the Executive and the Company shall, at the
Company's expense, obtain the opinions, which need not be unqualified, of legal
counsel and certified public accountants or a firm of recognized executive
compensation consultants. The Executive shall select said legal counsel,
certified public accountants and executive compensation consultants; provided
that if the Company does not accept one (1) or more of the parties selected by
the Executive, the Company shall provide the Executive with the names of such
legal counsel, certified public accountants and/or executive compensation
consultants as the Company may select; if the Executive does not accept the
party or parties selected by the Company, the legal counsel, certified public
accountants and/or executive compensation consultants selected by the Executive
and the Company, respectively, shall select the legal counsel, certified public
accountants and/or executive compensation consultants, whichever is applicable,
who shall provide the opinions required by this Section 5.12(c). The opinions
required hereunder shall set forth (i) the amount of the Base Period Income of
the Executive, (ii) the present value of Total Payments and (iii) the amount and
present value of any excess parachute payments. In the event that such opinions
determine that there would be an excess parachute payment, the Termination
Payment or any other payment determined by such counsel to be includible in
Total Payments shall be reduced or eliminated as specified by the Executive in
writing delivered to the Company within thirty (30) days of his receipt of such
opinions or, if the Executive fails to so notify the Company, then as the
Company shall reasonably determine, so that under the bases of calculation set
forth in such opinions there will be no excess parachute payment. The provisions
of this Section 5.12(c), including the calculations, notices and opinions
provided for herein shall be based upon the conclusive presumption that the
compensation and benefits provided for in Section 5.4 hereof and any other
compensation, including but not limited to the Accrued Benefits, earned on or
after the date of Change of Control by the Executive pursuant to the Company's

                                       14
<PAGE>
compensation programs if such payments would have been made in the future in any
event, even though the timing of such payment is triggered by the Change of
Control, are reasonable compensation for services rendered prior to the Change
of Control; provided, however, that in the event legal counsel so requests in
connection with the opinion required by this Section 5.12(c), a firm of
recognized executive compensation consultants, selected by the Executive and the
Company pursuant to the procedures set forth above, shall provide an opinion,
upon which such legal counsel may rely, as to the reasonableness of any item of
compensation as reasonable compensation for services rendered prior to the
Change of Control by the Executive. In the event that the provisions of Sections
280G and 4999 of the Code are repealed without succession, this Section 5.12(c)
shall be of no further force or effect.

     Notwithstanding anything to the contrary in this Section 5.12(c),
additional change of control payments made under Section 5.10 shall not be
subject to the limitations described herein. If, as a result of these Code
provisions, the Executive is required to pay excise tax by virtue of inclusion
of additional change of control payments under Section 5.10, then upon written
notice from the Executive to the Company, the Company shall pay the Executive an
amount equal to the total excise tax imposed on the Executive (including the
excise taxes on any excise tax reimbursements due pursuant to this sentence and
the excise taxes on any income tax reimbursements due pursuant to the next
sentence). If the Company is obligated to pay taxes for the Executive pursuant
to the preceding sentence, the Company also shall pay the Executive an amount
equal to the "total presumed federal and state taxes" that could be imposed on
the Executive with respect to the excise tax reimbursements due to the Executive
pursuant to the preceding sentence and the income tax reimbursements due to the
Executive pursuant to this sentence. For purposes of the preceding sentence, the
"total presumed federal and state taxes" that could be imposed on the Executive
shall be conclusively calculated using a combined tax rate equal to the sum of
the then prevailing maximum marginal federal and state income tax rates. No
adjustments will be made in this combined rate for the deduction of state taxes
on the federal return, the loss of itemized deductions or exemptions, or for any
other purpose. The Executive shall be responsible for paying the actual taxes.
The amounts payable to the Executive pursuant to this or any other agreement or
arrangement with Company shall not be limited in any way by the amount that may
be paid pursuant to the Code without the imposition of an excise tax or the loss
of Company deductions.

     5.13 Obligations of the Executive.

     (a) The Executive agrees that if, during the Employment Period, the
Executive's employment is terminated in a manner entitling the Executive to a
Termination Payment or the Executive has voluntarily terminated his employment,
the Executive shall not, for a period commencing on the Termination Date and
ending after one (1) year, (i) act in a similar capacity for any safety
technology company which competes to a substantial degree with the Company in
the aerospace and defense or automotive safety industries; or (ii) engage in any
activity involving substantial competition with the Company in the aerospace and
defense or automotive safety industries without the prior written approval of
the Company's President; provided,

                                       15
<PAGE>
however, that nothing in this Section 5.13(a) shall prohibit the Executive from
owning stock or other securities of a competitor amounting to less than five
percent (5%) of the stated capital of such competitor.

     (b) The Executive covenants and agrees, during the Executive's employment
by the Company and following his Termination Date, to hold in strict confidence
any and all proprietary information in the Executive's possession as a result of
the Executive's employment with the Company, including financial, legal,
marketing, technical and business information, contract and proposal
information, financial statements, and competition related information, but
excluding information that is generally available to the public or that
otherwise does not constitute proprietary information of the Company.

                                  SECTION SIX

     6.1 Enforcement.

     (a) All claims, disputes and other matters in question between the parties
arising under this Agreement, other than Section 5.12, shall be decided by
arbitration in accordance with the commercial rules of the American Arbitration
Association, unless the parties mutually agree otherwise. Any arbitration shall
be held in Phoenix, Arizona, unless the parties mutually agree otherwise. The
Company shall pay the costs of any such arbitration. The award by the arbitrator
shall be final, and judgment may be entered upon it in accordance with
applicable law in any state or Federal court having jurisdiction thereof.

     (b) If, after a Change of Control a good faith dispute arises with respect
to the enforcement of the Executive's rights under this Agreement or if any
arbitration or legal proceeding shall be brought in good faith to enforce or
interpret any provision contained herein, or to recover damages for breach
hereof and the Executive is the prevailing party, the Executive shall recover
from the Company any reasonable attorney's fees and necessary costs and
disbursements incurred as a result of such dispute or legal proceeding, and
prejudgment interest on any money judgment obtained by the Executive calculated
at the rate of interest announced by Bank One Trust Company, N. A. (or any
successor thereto) from time to time as its prime rate from the date that
payments to the Executive should have been made under this Agreement.

     6.2 Payment Obligations Absolute. The Company's obligation during and after
the Employment Period to insure that the compensation and arrangements provided
herein are provided to the Executive shall be absolute and unconditional and
shall not be affected by any circumstances, provided that the Company may apply
amounts payable under this Agreement to any loan or other debts then owed to the
Company or an Affiliate by the Executive, the terms of which are reflected in a
written document signed by the Executive. The amounts payable under this
Agreement shall be in lieu of any amounts payable to the Executive under a
separate severance plan, agreement or arrangement established by the Company.
All amounts payable by the Company under this Agreement shall be paid without
notice or demand. Each and

                                       16
<PAGE>
every payment made under this Agreement by the Company shall be final.
Notwithstanding the foregoing, in the event that the Company has paid an
Executive more than the amount to which the Executive is entitled under this
Agreement, the Company shall have the right to recover all or any part of such
overpayment from the Executive or from whomsoever has received such amount.

     6.3 Severability. In the event that a court of competent jurisdiction
determines that any portion of this Agreement is in violation of any statute or
public policy, then only the portions of this Agreement which violate such
statute or public policy shall be stricken. All portions of this Agreement which
do not violate any statute or public policy shall continue in full force and
effect. Further, any court order striking any portion of this Agreement shall
modify the stricken terms as narrowly as possible to give as much effect as
possible to the intentions of the parties under this Agreement.

     6.4 Governing Law. This Agreement shall be governed in all respects,
whether as to validity, construction, capacity, performance, or otherwise, by
the laws of the State of Arizona, and no action involving this Agreement may be
brought except in the Superior Court for the State of Arizona or the Federal
District Court for the District of Arizona, subject to Section 6.1.

                                 SECTION SEVEN

     7.1 Amendment or Termination.

     (a) This Agreement sets forth the entire agreement between the Executive
and the Company with respect to the subject matter hereof, and supersedes all
prior oral or written negotiations, commitments, understandings and writings
with respect thereto. This Agreement may not be terminated, amended or modified
during its term as specified above except by written instrument executed by the
Company and the Executive.

     (b) Upon the proper termination of this Agreement by the Company for any
reason whatsoever, or upon the termination of this Agreement by the Executive,
this Agreement shall thereupon be and become void and of no further force or
effect, except that the arbitration provisions of Section 6.1 shall continue to
govern any disputes arising hereunder. Any payments due pursuant to the terms of
this Agreement for services rendered prior to the termination shall be made as
provided in this Agreement.

     (c) The provisions of SECTION FIVE of this Agreement shall be effective
until October 13, 2003, and shall continue for additional two (2) year periods
thereafter, unless the Company notifies the Executive in writing one (1) year
prior to October 13, 2003 (or the second anniversary of that date, or the date
of notification of termination, in the event the Agreement continues beyond that
date pursuant to the provisions of this Section 7.1(c)) that it does not intend
to continue those provisions of the Agreement. Notwithstanding the foregoing,
(i) if a Change of Control has occurred on or before the date on which the
Agreement would be terminated by the Company in

                                       17
<PAGE>
accordance with this Section 7.1, the Agreement shall not terminate with respect
to that Change of Control until the end of the Employment Period, and (ii) this
Agreement shall terminate if, prior to a Change in Control, the Executive ceases
to be employed by the Employer as a corporate officer.

                                 SECTION EIGHT

     8.1 Assignment and Successors.

     (a) Except as otherwise provided in this Section 8.1, this Agreement is
personal in its nature and neither of the parties hereto shall, without the
consent of the other, assign or transfer this Agreement or any rights or
obligations hereunder.

     (b) If all or substantially all of the Company's business and assets are
sold, assigned or transferred to any Person, or if the Company merges into or
consolidates or otherwise combines with any Person which is a continuing or
successor entity, then the Company shall assign all of its right, title and
interest in this Agreement as of the date of such event to the Person which is
either the acquiring or successor corporation, and such Person shall assume and
perform from and after the date of such assignment the terms, conditions and
provisions imposed by this Agreement upon the Company. Failure of the Company to
obtain such assignment shall be a breach of this Agreement. In case of such
assignment by the Company and of assumption and agreement by such Person, all
further rights as well as all other obligations of the Company under this
Agreement thenceforth shall cease and terminate and thereafter the expression
"the Company" wherever used herein shall be deemed to mean such Person(s).

     (c) This Agreement and all rights of the Executive shall inure to the
benefit of and be enforceable by the Executive's personal or legal
representatives, estate, executors, administrators, heirs and beneficiaries. In
the event of the Executive's death, all amounts payable to the Executive under
this Agreement shall be paid to the Executive's estate. This Agreement shall
inure to the benefit of, be binding upon and be enforceable by, any successor,
surviving or resulting corporation or other entity to which all or substantially
all of the Company's business and assets shall be transferred whether by merger,
consolidation, transfer or sale. This Agreement shall not be terminated by the
voluntary or involuntary dissolution of the Company.

terms, covenants or conditions hereof shall not be deemed a waiver of such term,
covenant or condition, nor shall any waiver or relinquishment of, or failure to

more times be deemed a waiver or relinquishment of such right or power at any
other time or times.

     10.2 Withholding. The Company shall be entitled to withhold from amounts to
be paid to the Executive under this Agreement any federal, state or local
withholding or other taxes or charges which it is from time to time required to

     Re: Change of Control and Severance Agreement

Dear Jack:

     In addition to the terms identified in Mr. Riggs' January 29, 2002 offer
letter, you shall be entitled to the following compensation and benefits in the
event of a change of control of the Company or the termination of your
employment:

     1. Base compensation in the amount of $16,666.66 per month for a period of
one year from the date of termination or Change of Control (as defined
hereafter);

     2. Health benefits coverage for you and your eligible dependents for one
year from the date of termination or change of control, under the same terms and
conditions, by the medical and dental plan maintained by the Company that
covered you and your eligible dependents prior to the date of termination or
change of control;

     3. Life insurance coverage and 401(k) eligibility for one year from the
date of termination or change of control, under the same terms and conditions,
by the life insurance and 401(k) plan maintained by the Company that you
participated in prior to the date of termination or change of control; and

     4. In the event of a Change of Control, any stock options owned by or
granted to you shall be deemed immediately vested and shall be exercisable
according to their terms for the balance of the term of years of such options.

     Please note that the foregoing will be forfeited if your employment is
terminated "for cause," or if you voluntarily terminate employment for other
than "good reason." For purposes of this Agreement, termination "for cause"
shall mean termination resulting from: (1) conduct that has caused demonstrable
injury to the Company, monetary or otherwise; (2)
<PAGE>
Page 2 of 2

continued failure for thirty (30) days to perform your essential job functions,
duties or responsibilities (unless significantly changed without your consent)
as defined by the Company's CEO; (3) a violation of the Company's established
policies and procedures in effect while employed which could subject you to
disciplinary action by the Company; or (4) a criminal conviction, as evidenced
by a binding and final judgment, order or decree of a court of competent
jurisdiction, in effect after exhaustion or lapse of all rights of appeal.

     Termination for "good reason" shall mean a voluntary termination resulting
from: (1) your voluntary resignation from the position of CFO within 180 days
after a change of control; (2) a required relocation, without your consent, to
an employment location that is more than twenty-five (25) miles from your
employment location; (3) a significant reduction in your compensation and/or
benefits as in effect on the first date of employment; or (4) a significant
adverse change, without your written consent, in the nature or scope of your
authority, powers, functions, duties or responsibilities, which change or
reduction is not generally effective for all Executives employed by the Company
in your class or category.

     The definition of "Change of Control" shall be identical to the definition
provided in the Agreements of the Company's Executives, which are incorporated
