                                    ADDENDUM

         To "Standard Industrial/Commercial Multi-Tenant Lease-- Gross"

              Of the "American Industrial Real Estate Association"

                      Executed on or about 15 October 2002

           DEL MAR AVIONICS, Lessor, and HIENERGY TECHNOLOGIES, Lessee

                                  01 July 2003

WHEREAS, Lessee desires to lease additional parking area for construction and
temporary operation of a Secure Area and protected "radiation use zone" area for
research and development of fast neutron generation and impact upon nuclei of
substances within defined enclosures in said Secure Area for observation of
characteristic photon, gamma ray, distributions emanating from said neutron
nuclear impact to yield a definitive photon spectrum and thereby determine a
chemical composition of substances within said enclosures

WHEREAS, Lessor is willing to lease for a temporary period (not to exceed six
"6" months) a defined secure area (40' X 60') of the Del Mar Avionics Technology
parking area for a period, not to exceed six (6) months, to Lessee, said
protected area being more clearly delineated in the attached map and schedule.

NOW THEREFORE, in consideration of the aforesaid intention of parties hereto,
Lessor and Lessee agree to be bound to the following mutually assented to
provisions

BASE RENT SCHEDULE

Monthly rent shall be established at $50/ft2. for a 40' X 60' specified Secure
Area = 2400 ft 2. Monthly rent shall therefore be $1200/month commencing 1 July
2003

PERIOD

Lease period shall commence on 1 July 2003 and continue on a month to month
basis thereafter.

Term for the lease period shall, however, be on the month to month basis not to
exceed six (6) months total duration.

PROPERTY ALTERATION

It is understood that it is Lessee's intention to build a concrete enclosure
within said Secure Area with thick walls to prevent spurious transmission of
nuclear particles from the enclosed area. It is also understood that alteration
of the ground support may also have to be made to support the heavy concrete
enclosure structure. Parties hereto both understand that it is exclusively
Lessee's responsibility to prepare for and construct said concrete enclosure,
and it is also exclusively Lessee's responsibility to return the premises to
their previous state and normal parking area state upon termination of said
lease. Repair and reconstruction of the Secure Area premises must be
accomplished in a timely manner and within the thirty day notice to terminate
period.

HAZARDOUS WASTE AND MATERIALS

Lessee agrees to store hazardous waste, if any, securely within the leased
Secure Area in appropriate containers. Lessee shall be responsible for proper
disposal and safe guarding of any and all hazardous wastes. Hazardous materials,
on the other hand, such as nuclear and radioactive materials must comply with
state and federal EPA, NRC, and AEC requirements as well as the following
provisions.

the State of California for a license or licenses for the use on the leased
premises of the equipment required for the development and testing of the
detection technologies of Lessee including but not limited to standard
commercially available sealed capsule of an Americium-Beryllium source and
electrically powered neutron generators. Lessor understands that said type of
equipment is essential for the operation of Lessee, and Lessor hereby grants
permission for the use of the equipment provided, however, that:

all required State & Federal licenses have been granted and copies thereof
supplied to Lessor;

location and shielding of the equipment will provide radiation safety under the
State and Federal regulations;

radiation monitoring, and calibration of the monitoring instruments, will be
done regularly by the State Licensed and experienced University of California
Radiation Safety Officer;

Lessee will not store radioactive waste in or outside the leased premises, and
shall arrange for state approved pick up and disposal of any discarded
radioactive wastes or by-products at Lessee's expense.

SECURITY

As additional security of the Secured Area, Lessee shall install a temporary
chain link fence around the perimeter of the Secured Area which can be accessed
only through a locked gate. All vehicles associated with the Secured Area
activities or Lessee's activities in general must be parked within the fence of
said Secured Area or in Lessee's normal parking area near Building 1601.

PERSONAL PROPERTY OF LESSEE

No hazardous property or materials of Lessee shall be kept within said Secured
Area at times when said premises are not under close and active visual
supervision.

<PAGE>

LESSEE LIABILITY

Notwithstanding anything to the contrary set forth in this Lease, unless caused
by Lessee or Lessee's employees, agents or contractors (collectively, "Lessee's

and shall comply with all current and future applicable requirements and
building permits that relate to the premises, or the project of which the
premises are to be used. Lessee shall be liable for the cost of complying with

               account as security for a loan from the NASD Dealer in the amount
               of the Exercise  Price,  and whereby the NASD Dealer  irrevocably
               commits upon receipt of such shares to forward the Exercise Price
               directly to the Company; or

          (i)  any combination of the foregoing  methods of payment or any other
               consideration  or  method of  payment  as shall be  permitted  by
               a1pplicable corporate law.

5.4.     TERM AND TERMINATION OF OPTIONS.

The term and provisions for termination of each Option shall be as fixed by the
Administrator, but no Option may be exercisable more than ten (10) years after
the date it is granted. An Incentive Option granted to a person who is a 10%
Shareholder on the date of grant shall not be exercisable more than five (5)
years after the date it is granted.

5.5.     VESTING AND EXERCISE OF OPTIONS.

Each Option shall vest and become exercisable in one or more installments at
such time or times and subject to such conditions, including without limitation
the achievement of specified performance goals or objectives, as shall be
determined by the Administrator and set forth in an Option Agreement; provided,
however that Options granted to employees who are not officers, directors or
Service Providers shall vest and become exercisable in installments at a minimum
rate of 20% per year over a period of five (5) years from the date the Option is
granted.

5.6.     ANNUAL LIMIT ON INCENTIVE OPTIONS.

To the extent required for "incentive stock option" treatment under Section 422
of the Code, the aggregate Fair Market Value (determined as of the time of
grant) of the Common Stock shall not, with respect to which Incentive Options
granted under this Plan and any other plan of the Company or any Affiliated
Company become exercisable for the first time by an Optionee during any calendar
year, exceed $100,000. To the extent such dollar limitation is exceeded, the
excess portion of such Option shall be exercisable as a Nonqualified Option
under the Federal tax laws.

5.7.     LIMITED TRANSFERABILITY.

No Incentive Option or Nonqualified Option shall be assignable or transferable
except by will or the laws of descent and distribution, and during the life of
the Optionee shall be exercisable only by such Optionee. Notwithstanding the
foregoing, shares purchased upon exercise of Options may be transferred or
assigned in whole or in part during the Optionee's lifetime, provided that the
transferee agrees to be bound by the same transfer restrictions applicable to
the Participant, either (a) in connection with the Optionee's estate plan to one
or more members of the Optionee's immediate family, including any parent,
descendant, spouse, brother, sister, grandparent, grandchild, dependent, or
member of their immediate families, or to a trust established exclusively for
one or more such persons, or (b) in a transfer described in Section 1041(a) of
the Code between spouses or incident to divorce. The terms applicable to the
assigned portion of the shares shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Administrator may deem appropriate. In
the event that applicable tax law and Section 25102(o) of the California
Corporate Securities Law of 1968 permit transferability of Options in any
particular case, then with the consent of the Administrator in such case, an
Option may be transferred consistent with restrictions under law and subject to
any terms or restrictions imposed by the Administrator.

5.8.     NO RIGHTS AS SHAREHOLDER.

An Optionee or permitted transferee of an Option shall have no rights or
privileges as a shareholder with respect to any shares covered by an Option
until such Option has been duly exercised and certificates representing shares
purchased upon such exercise have been issued to such person.

5.9.     COMPANY'S REPURCHASE RIGHTS.

In the event of termination of a Participant's Continuous Service for any reason
whatsoever (including death or disability), the Option Agreement may provide, in
the discretion of the Administrator or upon events specified in the discretion
of the Administrator, that the Company, or its assignee, shall have the right,
exercisable at the discretion of the Administrator, to repurchase shares of
Common Stock acquired pursuant to the exercise of an Option at any time,

                                       6
<PAGE>

at any price, and on any terms as set forth in the Option  Agreement  evidencing
such Options.

5.10.    OTHER RESTRICTIONS ON UNDERLYING SHARES OF COMMON STOCK.

Shares of Common Stock issued pursuant to the exercise of an Option may not be
sold, assigned, transferred, pledged or otherwise encumbered or disposed of
except as specifically provided in the Option Agreement.

6.       RIGHTS TO PURCHASE.

6.1.     NATURE OF RIGHT TO PURCHASE.

A Right to Purchase granted to an Offeree entitles the Offeree to purchase, for
a Purchase Price determined by the Administrator, shares of Common Stock subject
to such terms, restrictions and conditions as the Administrator may determine at
the time of grant ("Restricted Stock"). Such conditions may include, but are not
limited to, Continuous Service or the achievement of specified performance goals
or objectives. The Administrator shall have the discretion to grant options, or
amend outstanding options, such that the unvested portion of options is
exercisable for Restricted Stock.

6.2.     ACCEPTANCE OF RIGHT TO PURCHASE.

An Offeree shall have no rights with respect to the Restricted Stock subject to
a Right to Purchase unless the Offeree shall have accepted the Right to Purchase
within ten (10) days (or such longer or shorter period as the Administrator may
specify) following the grant of the Right to Purchase by making payment of the
full Purchase Price to the Company in the manner set forth in Section 6.3 hereof
and by executing and delivering to the Company a Restricted Stock Purchase
Agreement. Each Restricted Stock Purchase Agreement shall be in such form, and
shall set forth the Purchase Price and such other terms, conditions and
restrictions of the Restricted Stock, not inconsistent with the provisions of
this Plan, as the Administrator shall, from time to time, deem desirable. Each
Restricted Stock Purchase Agreement may be different from each other Restricted
Stock Purchase Agreement.

6.3.     PAYMENT OF PURCHASE PRICE.

Subject to any legal restrictions, payment of the Purchase Price upon acceptance
of a Right to Purchase Restricted Stock may be made, in the discretion of the
Administrator, by--

          (a) cash;

          (b)  check (considered payment only when honored by the bank against
               which it is drawn upon first presentment);

          (c)  the surrender of shares of Common Stock owned by the Offeree that
               have been held by the Offeree for at least six (6) months, which
               surrendered shares shall be valued at Fair Market Value as of the
               date of such exercise;

          (d)  the Offeree's promissory note in a form and on terms acceptable
               to the Administrator;

          (e)  the cancellation of indebtedness of the Company to the Offeree;

          (f)  the waiver of compensation due or accrued to the Offeree for
               services rendered; or

          (g)  any combination of the foregoing methods of payment or any other
               consideration or method of payment as shall be permitted by
               applicable corporate law.

6.4.     RIGHTS AS A SHAREHOLDER.

Upon complying with the provisions of Section 6.2 hereof, an Offeree shall have
the rights of a shareholder with respect to the Restricted Stock purchased
pursuant to the Right to Purchase, including voting and dividend rights, subject
to the terms, restrictions and conditions as are set forth in the Restricted
Stock Purchase Agreement. Unless the Administrator shall determine otherwise,
certificates evidencing shares of Restricted Stock shall remain in the
possession of the Company in accordance with the terms of the Restricted Stock
Purchase Agreement until such shares have vested.

6.5.     RESTRICTIONS.

Shares of Restricted Stock may not be sold, assigned, transferred, pledged or
otherwise encumbered or disposed of except as specifically provided in the
Restricted Stock Purchase Agreement or by the Administrator. In the event of
termination of a Participant's employment, service as a director of the Company
or Service Provider status for any

                                       7
<PAGE>

reason whatsoever (including death or disability), the Restricted Stock Purchase
Agreement may provide, in the discretion of the Administrator,  that the Company
shall have the right, exercisable at the discretion of the Administrator or upon
events specified in the discretion of the Administrator, to repurchase

          (i)  at the original Purchase Price, any shares of Restricted Stock
               which have not vested as of the date of termination, and

          (ii) at Fair Market Value (or at the original Purchase Price in
               specified events), any shares of Restricted Stock which have
               vested as of such date, on such terms as may be provided in the
               Restricted Stock Purchase Agreement;

provided that, for Restricted Stock granted to employees who are not officers,
directors or Service Providers, the Company's Repurchase Right at the original
purchase price lapses at a minimum rate of 20% per year over a period of five
(5) years from the date the Right to Purchase was granted.

6.6.     VESTING OF RESTRICTED STOCK.

Each Restricted Stock Purchase Agreement shall specify the date or dates, the
performance goals or objectives which must be achieved, and any other conditions
on which the Restricted Stock may vest, as may be established in the discretion
of the Administrator.

6.7.     DIVIDENDS.

If payment for shares of Restricted Stock is made by promissory note, any cash
dividends paid with respect to the Restricted Stock may be applied, in the
discretion of the Administrator, to repayment of such note.

6.8.     LIMITED ASSIGNABILITY OF RIGHTS.

No Right to Purchase shall be assignable or transferable except by will or the
laws of descent and distribution. Restricted Stock may, in connection with the
Participant's estate plan, be assigned in whole or in part during the
Participant's lifetime to one or more members of the Participant's immediate
family, , including any parent, descendant, spouse, brother, sister,
grandparent, grandchild, dependent, or member of their immediate families, or to
a trust established exclusively for one or more such persons, or to a trust
established exclusively for one or more such family members. The terms
applicable to the assigned portion shall be the same as those in effect for the
Restricted Stock immediately prior to such assignment and shall be set forth in
such documents issued to the assignee as the Plan Administrator may deem
appropriate. In the event that applicable tax law and Section 25102(o) of the
California Corporate Securities Law of 1968 permit transferability of Restricted
Stock in any other particular case, then with the consent of the Administrator
in such case, Restricted Stock may be transferred consistent with restrictions
under law and subject to any terms or restrictions imposed by the Administrator.

7.       ADMINISTRATION OF THE PLAN.

7.1.     ADMINISTRATOR.

Authority to control and manage the operation and administration of the Plan
shall be vested in the Board, which may delegate such responsibilities in whole
or in part to a committee consisting of two (2) or more members of the Board
(the "Committee"). Members of the Committee may be appointed from time to time
by, and shall serve at the pleasure of, the Board. As used herein, the term
"Administrator" means the Board or, with respect to any matter as to which
responsibility has been delegated to the Committee, the term Administrator shall
mean the Committee.

7.2.     POWERS OF THE ADMINISTRATOR.

In addition to any other powers or authority conferred upon the Administrator
elsewhere in the Plan or by applicable law, the Administrator shall have full
power and authority, at any time and from time to time, in any or each
particular instance or circumstance, as to each Option Agreement or Restricted
Stock Purchase Agreement, Optionee or Purchaser, independently of any other or
others, as determined in any or each instance in the sole and absolute
discretion of the Administrator:

          (a)  to determine the persons to whom, and the time or times at which,
               Incentive Options or Nonqualified Options shall be granted and
               Rights to Purchase shall be offered, the number of shares to be
               represented by each Option and Right to Purchase and the
               consideration to be received by the

                                       8
<PAGE>

               Company upon the exercise thereof;

          (b)  to interpret the Plan;

          (c)  to create, amend or rescind rules and regulations relating to the
               Plan;

          (d)  to determine the terms, conditions and restrictions contained in,
               and the form of, any or all Option Agreements and Restricted
               Stock Purchase Agreements;

          (e)  to determine the identity or capacity of any persons who may be
               entitled to exercise a Participant's rights under any Option or
               Right to Purchase under the Plan;

          (f)  to correct any defect or supply any omission or reconcile any
               inconsistency in the Plan or in any Option Agreement or
               Restricted Stock Purchase Agreement;

          (g)  to extend the exercise date or any relevant date of any Option or
               acceptance date or other relevant date of any Right to Purchase,
               or to waive any other right of the Company to insist on prompt
               performance;

          (h)  to provide for any rights of first refusal and/or any repurchase
               rights and the terms, provisions and conditions thereof, if any,
               and their performance, waiver, modification or termination, or
               any of the above in combination;

          (i)  to effect, with the consent of the affected Participant or
               pursuant to the terms of the Plan, the cancellation of any or all
               outstanding Options and to grant, in respect of any or all
               thereof in substitution, new options covering the same or
               different number of shares of Common Stock but with an exercise
               price per share based on the Fair Market Value on the new grant
               date with any or all adjustments thereto, in either case in any
               such manner as the Adminstrator deems to be reasonable,
               equitable, appropriate or advisable;

          (i)  to amend any outstanding Option Agreements and any outstanding
               Restricted Stock Purchase Agreements, and by way of example but
               not limitation to provide for, among other things, any change or
               modification to a provision thereof which the Administrator could
               have provided for upon the grant of an Option or Right to
               Purchase or upon the issuance of Restricted Stock or could have
               otherwise done in furtherance of the powers or discretion
               provided for herein; and

          (j)  to make all other determinations and take all other actions, or
               refrain therefrom, as considered necessary or advisable for the
               administration of the Plan, or the performance of its terms in
               the name of the Company or its successors, but only to the extent
               not contrary to the express provisions of the Plan, in the sole
               and absolute discretion of the Administrator.

Any action, decision, interpretation or determination made in good faith by the
Administrator in the exercise of its authority conferred upon it under the Plan
shall be final and binding on the Company and all Participants. Notwithstanding
anything to the contrary, the Administrator's discretion under this Plan extends
to and includes the authorization to deal with any one or more individual Option
Agreements or individual Restricted Stock Purchase Agreements independently of
any or all others then outstanding under the Plan in the discretion of the
Administrator, and such authority and discretion are not intended to be limited
by, and there is no actual or implied requirement of, consistency among various
Option Agreements or Restricted Stock Purchase Agreements, respectively, under
any circumstances.

7.3.     LIMITATION ON LIABILITY.

No employee of the Company or member of the Board or Committee shall be subject
to any liability with respect to duties under the Plan unless the person acts
fraudulently or in bad faith. To the extent permitted by law, the Company shall
indemnify each member of the Board or Committee, and any employee of the Company
with duties under the Plan, who was or is a party, or is threatened to be made a
party, to any threatened, pending or completed proceeding, whether civil,
criminal, administrative or investigative, by reason of such person's conduct in
the performance of duties under the Plan.

8.       MERGERS AND OTHER REORGANIZATIONS.

8.1.     MERGERS AND OTHER REORGANIZATIONS.

An Option Agreement or Restricted Stock Purchase Agreement may make provision
for what, if anything, shall happen in the event that the Company at any time
proposes to enter into any transaction approved by the Board to dissolve,
liquidate, sell substantially all of its assets, merge or consolidate, acquire
property or shares, separate or

                                       9
<PAGE>

reorganize, with any other entity or entities, corporate or otherwise, as a
result of which either the Company is not the surviving corporation or the
Company is the surviving corporation. The Plan and outstanding Options, Rights
of Purchase, and Restricted Stock shall in no way affect the right of the
Company to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

8.2.     CHANGE IN CONTROL.

An Option Agreement or Restricted Stock Purchase Agreement may make provision
for what, if anything, shall happen to the terms of any or every outstanding
Option Agreement or Restricted Stock Purchase Agreement in the event that the
Company at any time proposes to enter into any transaction that results in a
Change of Control.

8.3.     HOSTILE TAKEOVER.

The Administrator shall have the discretionary authority to structure Option
Agreements and Restricted Stock Purchase Agreements such that the Company's
Repurchase Rights shall terminate and such shares shall vest automatically upon
the consummation of a Hostile Take-Over, to condition the automatic acceleration
of one or more Options and the termination of one or more of the Company's
Repurchase Rights under Restricted Stock Purchase Agreements upon the
involuntary termination of the Participant's Continuous Service within a
designated period (not to exceed eighteen (18) months) following the effective
date of a Hostile Take-Over, and to make provision that each Option so
accelerated shall remain exercisable for fully-vested shares until a date not
later than the expiration of the option term.

9.       AMENDMENT AND TERMINATION OF THE PLAN.

9.1.     AMENDMENTS.

The Board shall have full power and authority (subject to certain amendments
requiring shareholder approval pursuant to applicable laws or regulations) from
time to time to alter, amend, suspend or terminate the Plan in any or all
respects as the Board may deem advisable. No such alteration, amendment,
suspension or termination shall be made which shall substantially affect or
impair the rights of any Participant under an outstanding Option Agreement or
Restricted Stock Purchase Agreement without such Participant's consent. The
Board may alter or amend the Plan to comply with requirements under the Code
relating to Incentive Options or other types of options which give Optionees
more favorable tax treatment than that applicable to Options granted under this
Plan. Upon any such alteration or amendment, any outstanding Option granted
hereunder may, if the Administrator so determines and if permitted by applicable
law, be subject to the more favorable tax treatment afforded to an Optionee
pursuant to such terms and conditions.

9.2.     PLAN TERMINATION.

Unless the Plan shall theretofore have been terminated, the Plan shall terminate
on the tenth (10th) anniversary of the Effective Date and no Options or Rights
to Purchase may be granted under the Plan thereafter, but Option Agreements,
Restricted Stock Purchase Agreements and Rights to Purchase then outstanding
shall continue in effect in accordance with their respective terms.

10.      CANCELLATION & RESCISSION

10.1.    NON-COMPETITION.

Unless a particular Option Agreement or a particular Restricted Stock Purchase
Agreement specifies otherwise, the Administrator may cancel, rescind, suspend,
withhold or otherwise limit or restrict any Options or Common Stock at any time
if the Participant engages in any "Adverse Activity." For purposes of this
Section 10, "Adverse Activity" shall include: (i) the rendering of services for
any organization or engaging directly or indirectly in any business which is or
becomes competitive with the Company, or which organization or business, or the
rendering of services to such organization or business, is or becomes otherwise
prejudicial to or in conflict with the interests of the Company; (ii) the
disclosure to anyone outside the Company, or the use in other than the Company's
business,

                                       10
<PAGE>

without prior written authorization from the Company, of any confidential
information or material relating to the business of the Company, acquired by the
Participant either during or after employment with the Company; (iii) the
failure or refusal to disclose promptly and to assign to the Company all right,
title and interest in any invention or idea, patentable or not, made or
conceived by the Participant during employment by the Company, relating in any
manner to the actual or anticipated business, research or development work of
the Company; (iv) activity that results in termination of Participant's
Continuous Service for "cause," defined here to mean those acts identified in
Section 2924 of the California Labor Code; (v) any material violation of any
terms or provisions of this Agreement; or (vi) any attempt directly or
indirectly to induce any employee of the Company to be employed or perform
services elsewhere or any attempt directly or indirectly to solicit the trade or
business of any current or prospective customer, supplier or partner of the
Company.

10.2     AGREEMENT UPON EXERCISE.

In the event a Participant fails to comply with the provisions of paragraphs
(i)-(vi) of Section 10.1 prior to, or during the six (6) months after, any
exercise pursuant to an Option Agreement or a purchase pursuant to a Restricted
Stock Purchase Agreement, such exercise or purchase may be rescinded at the
Company's sole election within two years thereafter. In the event of any such
rescission, the Participant shall pay to the Company the amount of any gain
realized or payment received as a result of the disposition of Options or Common
Stock acquired pursuant to such exercise or purchase, in such manner and on such
terms and conditions as may be required, and the Company shall be entitled to
set-off against the amount of any such gain any amount owed to the Participant
by the Company.

11.      TAX WITHHOLDING.

The Company shall have the power to withhold, or require a Participant to remit
to the Company, an amount sufficient to satisfy any applicable U.S. federal,
state, or local tax withholding requirements with respect to any Options
exercised or Restricted Stock issued under the Plan. The Company's obligation to
deliver shares of Common Stock upon the exercise of Options or the issuance or
vesting of Common Stock under the Plan shall be subject to the satisfaction of
all applicable U.S. federal, state and local income and employment tax
withholding requirements. To the extent permissible under applicable tax,
securities and other laws, the Administrator may, in its sole discretion and
upon such terms and conditions as it may deem appropriate, permit a Participant
to satisfy his or her obligation to pay any such tax, in whole or in part, up to
an amount determined on the basis of the highest marginal tax rate applicable to
such Participant, by--

          (a)  directing the Company to apply shares of Common Stock to which
               the Participant is entitled as a result of the exercise of an
               Option or as a result of the purchase of or lapse of restrictions
               on Restricted Stock

               or

          (b)  delivering to the Company shares of Common Stock owned by the
               Participant.

          The shares of Common Stock so applied or delivered in satisfaction of
          the Participant's tax withholding obligation shall be valued at their
          Fair Market Value as of the date of measurement of the amount of
          income subject to withholding.

12.      MISCELLANEOUS.

12.1.    BENEFITS NOT ALIENABLE.

Other than as provided above, benefits under the Plan may not be transferred,
assigned or alienated, whether voluntarily or involuntarily or by operation of
law. Any unauthorized attempt at assignment, transfer, pledge or other
disposition shall be void and without force or effect whatsoever.

12.2. NO CREATION OR ENLARGEMENT OF PARTICIPANT'S RIGHTS TO CONTINUE IN ANY
      CAPACITY.

This Plan is strictly a voluntary undertaking on the part of the Company and
shall not be deemed to constitute a contract between the Company and any
Participant for, or to be consideration for, or an inducement to, or a condition
of, the continuation of any Participant's services to the Company in any
capacity. Nothing contained in the Plan

                                       11
<PAGE>

shall be deemed to give the right to any Participant to be retained in the
service of the Company or any Affiliated Company or to interfere with the right
of the Company or any Affiliated Company (which rights are hereby expressly
reserved by each) to discharge or discontinue the services of any Participant at
any time for any reason, with or without cause.

12.3.    APPLICATION OF FUNDS.

The proceeds received by the Company from the sale of Common Stock pursuant to
Option Agreements and Restricted Stock Purchase Agreements, except as otherwise
provided herein, will be used for general corporate purposes.

12.4.    ANNUAL AND OTHER PERIODIC REPORTS.

The Company shall make available to Participants or cause to be made available
to Participants, either electronically or in the form of paper copies, all
annual and other periodic financial and informational reports that the Company
distributes generally to its shareholders, except if Participants are key
employees with duties that assure the equivalent access to information.

12.5.    ACTION TO ENFORCE

In the event that a Participant brings an action to enforce the terms of the
Plan or any Option Agreement or Restricted Stock Purchase Agreement and the
Company prevails, the Participant shall pay all costs and expenses incurred by
the Company in connection with that action, including reasonable attorney's fees
and costs, including reasonable attorney's fees and costs incurred by the
Company in connection with collection.

12.6.    SEVERABILITY AND INTERPRETATION

If any provision of the Plan is or becomes or is deemed invalid, illegal or
unenforceable in any jurisdiction, or would disqualify the Plan or any Option
Agreement or Restricted Stock Purchase Agreement under any law deemed applicable
by the Administrator, such provision shall be construed or deemed amended or
limited in scope to conform to applicable laws or, in the discretion of the
Administrator, it shall be stricken and the remainder of the Plan shall remain
in full force and effect.

12.7.    GOVERNING LAW

The Plan and each Option Agreement or Restricted Stock Purchase Agreement shall
be governed by the laws of the State of California, excluding any conflicts of
law or choice of law rule or principle that might otherwise refer construction
and interpretation of the plan and such agreements to the substantive law of
another jurisdiction. Unless otherwise provided in the Option Agreement or
Restricted Stock Purchase Agreement, Participants are deemed to submit to the
exclusive jurisdiction and venue of federal or state courts of Orange County,
California, to resolve any and all issues that may arise out of or relate to the
Plan or any Option Agreement or Restricted Stock Purchase Agreement.

12.8.    EFFECTIVE DATE

The Plan shall become effective on the Effective Date.

Stock of the Company at a purchase price of ___________ (___________) per share
(the "Exercise Price"), subject to the terms and conditions set forth herein and
the provisions of the Plan. If the box marked "Incentive" above is checked, then
this Option is intended to qualify as an "incentive stock option" as defined in
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). If
this Option fails in whole or in part to qualify as an incentive stock option,
or if the box marked "Nonqualified" is checked, then this Option shall to that
extent constitute a nonqualified stock option.

2.       VESTING OF OPTION.

2.1.     VESTING SCHEDULE.

The right to exercise this Option shall vest in installments, and this Option
shall be exercisable from time to time in whole or in part as to any vested
installment. Vesting will be measured from ___________ (the "Vesting Measurement
Date"). No additional Shares shall vest after the date of termination of
Optionee's "Continuous Service" (the "Service Termination Date"). As used
herein, the term "Continuous Service" has the meaning given in the Plan. Except
as may otherwise be provided in this Agreement, the vesting schedule is as
follows:

<TABLE>
<CAPTION>
On or After:..............................................................................Option Exercisable As To:
-----------                                                                               ------------------------

<S>                                                                                             <C>
First anniversary of Vesting Measurement Date:..................................................____% of the Shares

Last day of each calendar month after such first anniversary....................................____% of the Shares

</TABLE>

The vesting schedule of this Option would result, assuming the Service
Termination Date shall not have theretofore occurred, in this Option being
exercisable as to One Hundred Percent (100%) of the Shares covered by this
Option at the end of the calendar month in which the _______ anniversary of the
Vesting Measurement Date falls.

2.2.     CHANGE IN CONTROL.

In the event of a Change in Control (as defined in the Plan), the Administrator
in its discretion may take one or more of the following actions with respect to
this Option (whether or not then exercisable or vested):

     (i)  provide for the purchase or exchange of this Option for an amount of
          cash or other property having a value equal to the difference, or
          spread, between

          (x)  the value of the cash or other property that the Optionee would
               have received pursuant to such Change in Control transaction in
               exchange for any shares issuable upon exercise of this Option, in
               the amount that the Optionee would have received had the then
               exercisable portion, if any, of this Option been exercised
               immediately prior to such Change in Control transaction, and

          (y)  the Exercise Price,

     (ii) adjust the terms of this Option in a manner determined by the
          Administrator to reflect the Change in Control,

<PAGE>

    (iii) cause this Option to be assumed, or new rights substituted therefor,
          by another entity, through the continuance of the Plan and the
          assumption of this Option, or the substitution for this Option of a
          new option of comparable value covering shares of a successor or
          parent corporation, with appropriate adjustments as to the number and
          kind of shares and Exercise Price, in which event the Plan and this
          Option, or the new option substituted therefor, shall continue in the
          manner and under the terms so provided,

     (iv) cancel this Option if this Option is deemed to have no net value on
          the basis described in paragraph 2.2(i) above or if the Option is not
          then exercisable by virtue of this Agreement, as then in effect, or

     (v)  make such other provision as the Administrator may consider equitable.

If the Administrator does not take any of the forgoing actions, this Option
shall terminate upon the consummation of the Change in Control and the
Administrator shall cause written notice of the proposed transaction to be given
to the Optionee not less than fifteen (15) days prior to the anticipated
effective date of the proposed transaction.

Option to be exercised as to the unvested portion prior to vesting, and in that
case to deliver Restricted Shares to the Optionee upon exercise of this Option.

<PAGE>

6.2.     INVESTMENT INTENT AS TO SHARES.

Optionee acknowledges that the Company may issue Shares upon the exercise of the
Option without registering such Shares under the Securities Act of 1933, as
amended (the "Act"), on the basis of certain exemptions from such registration
requirement. Accordingly, Optionee agrees that his or her exercise of the Option
may be expressly conditioned upon his or her delivery to the Company of an
investment certificate and agreement including such representations and
undertakings as the Company may reasonably require in order to assure the
availability of such exemptions, including representations, warranties and
agreements that--

     (a) The Optionee is purchasing the Shares solely for the Optionee's own
         account for investment and not with a view to or for sale or
         distribution of the Shares or any portion thereof and not with any
         present intention of selling, offering to sell or otherwise disposing
         of or distributing the Shares or any portion thereof. The Optionee also
         represents that the entire legal and beneficial interest of the Shares
         the Optionee is purchasing is being purchased for, and will be held for
         the account of, the Optionee only and neither in whole nor in part for
         any other person.

     (b) The Optionee has discussed the Company and its plans, operations and
         financial condition with its officers and that the Optionee has
         received all such information as the Optionee deems necessary and
         appropriate to enable the Optionee to evaluate the financial risk
         inherent in making an investment in the Shares of the Company, and has
         received satisfactory and complete information concerning the business
         and financial condition of the Company in response to all inquiries in
         respect thereof.

     (c) The Optionee realizes that the purchase of the Shares will be a highly
         speculative investment.

     (d) The Optionee is able, without impairing the Optionee's financial
         condition, to hold the Shares for an indefinite period of time and to
         suffer a complete loss on the investment.

     (e) The Optionee acknowledges that he is aware that the Shares to be issued
         to him by the Company pursuant to this Agreement have not been
         registered under the Act, and--

         (i)  the Shares must be held indefinitely unless a transfer of them is
              subsequently registered under the Act or an exemption from such
              registration is available;

         (ii) the share certificate(s) representing the Shares will be stamped
              with the legends restricting transfer as specified in this
              Agreement in Section 13 below; and

         (iii) the Company will make a notation in its records of the
              aforementioned restrictions on transfer and legends as described
              in Section 14 below.

     (f) The Optionee understands that the Shares are restricted securities
         within the meaning of Rule 144 promulgated under the Act; that the
         exemption from registration under Rule 144 will not be available in any
         event for at least one year from the date of sale of the Shares to the
         Optionee, and even then will not be available unless (i) a public
         trading market then exists for the Shares of the Company, (ii) adequate
         current public information concerning the Company is then available to
         the public, (iii) the Optionee has been the beneficial owner and the
         Optionee has paid the full purchase price for the Shares at least one
         year prior to the sale, and (iv) other terms and conditions of Rule 144
         are complied with; and that any sale of the Shares may be made by it
         only in limited amounts in accordance with such terms and conditions of
         Rule 144, as amended from time to time.

     (g) Without in any way limiting any of the other provisions of this
         Agreement, Optionee's further agreement that the Optionee shall in no
         event make any disposition of all or any portion of the Shares which
         the Optionee is purchasing unless and until:

         (i)  there is then in effect a Registration Statement under the Act
              covering such proposed disposition and such disposition is made in
              accordance with said Registration Statement; or

         (ii) (A) the Optionee shall have notified the Company of the proposed
              disposition and shall have furnished the Company with a detailed
              statement of the circumstances surrounding the proposed
              disposition, (B) the Optionee shall have furnished the Company
              with an opinion of counsel to the effect that such disposition
              will not require registration of such shares under the Act, and
              (C) such opinion of counsel shall have been concurred in by
              counsel for the Company and the Company shall have advised the
              Optionee of such concurrence.

     (h) The Optionee represents and warrants that he or she has not engaged in
         any Adverse Activity as defined in Section 3.8.

     (i) The Optionee acknowledges that the Optionee has been furnished with a
         copy of the Plan, has read the Plan and this Agreement, and understands
         that all rights and obligations connected with this Agreement are set
         forth in this Agreement and in the Plan.

other securities of the Company by reason of a recapitalization, stock split,
combination of shares, reclassification, stock dividend (in excess of two
percent (2%)) or other change in the capital structure of the Company, then
appropriate adjustments shall be made by the Administrator to the number of
Shares subject to the unexercised portion of this Option and to the Exercise
Price per share, in order to preserve, as nearly as practical, but not to
increase, the benefits of the Optionee under this Option, in accordance with the
provisions of the Plan. No fractional share shall be issued under this Option or
upon any such adjustment.

The right of the Company and any Affiliated Company (as defined in the Plan) to
terminate at will the Optionee's services to the Company or any Affiliated
Company at any time (whether by dismissal, discharge or otherwise), with or
without cause, is specifically reserved. Nothing in this Agreement shall
diminish or impair in any manner whatsoever the right or power of the Company or
any Affiliated Company to terminate the Optionee's Continuous Service for any
reason, with or without cause.

RSPA No.

                           HIENERGY TECHNOLOGIES, INC.
                       RESTRICTED STOCK PURCHASE AGREEMENT
                         UNDER 2003 STOCK INCENTIVE PLAN

This Restricted Stock Purchase Agreement is entered into as of ________, by and
between HiEnergy Technologies, Inc., a Delaware corporation (the "Company"), and
______________________ (the "Purchaser") pursuant to the Company's 2003 Stock
Incentive Plan (the "Plan").

1.       PURCHASE AND SALE OF SHARES.

The Purchaser hereby agrees to purchase from the Company, and the Company hereby
agrees to sell to the Purchaser, ____________ (____________) shares of its
Common Stock (the "Shares") for a purchase price of _________ (__________) per
share. The Shares shall be duly issued and a certificate or certificates for the
Shares are concurrently herewith being issued in the name of Purchaser.
Purchaser shall thereupon be a shareholder with respect to all of the Shares
represented by such certificate(s) and shall have all of the rights of a
shareholder with respect to all of the Shares, including the right to vote the
Shares and to receive all dividends and other distributions paid with respect to
the Shares, subject to the transfer restrictions provided in this Agreement. The
purchase price is payable as follows:

     (a) by delivery of cash,

     (b) by check (considered payment only when honored by the bank against
         which it is drawn upon first presentment);

     (c) by delivery of a promissory note payable to the Company, bearing
         interest from the date hereof and substantially in the form attached as
         Exhibit A; or

     (d) any combination of cash, check and promissory note, so long as the
         total consideration equals the aggregate purchase price as set forth
         above.

     In the event payment of any portion or all of the purchase price is to be
     made by delivery of a promissory note, Purchaser shall deliver to the
     Company a pledge of the Shares or other securities or assets which may be
     listed in the Pledge Agreement dated the date hereof and substantially in
     the form attached as Exhibit B. If the note is to be unsecured by the
     Shares or other collateral, the Pledge Agreement shall so indicate.

The Purchaser's rights to acquire the Shares hereunder are nontransferable other
than by will or the laws of descent and distribution, and Purchaser's legal
representative, his or her legatee, or the person who acquired the Purchaser
rights to acquire the Shares by reason of the death of the Purchaser shall
succeed to the Purchaser's rights and obligations under this Agreement. The
rights of the Purchaser under this Agreement also may be assigned and
transferred by the Purchaser (a) for estate planning purposes to members of the
immediate family of the Purchaser, including for this purpose, but not limited
to, spouses, parents, descendants, brothers and sisters, or to trusts
established for the benefit of such persons, and (b) in a transfer described in
Section 1041(a) of the Code between spouses or incident to divorce.

2.       INTERNAL REVENUE CODE SS. 83(B) ELECTION.

Purchaser hereby agrees to file the election provided under ss. 83(b) of the
Internal Revenue Code of 1986, as amended (herein called the "Code"), within
thirty (30) days of the transfer of the Shares, substantially in the form
attached as Exhibit C hereto and, if required, a comparable form of election
with the California Franchise Tax Board.

<PAGE>

The parties hereto acknowledge and agree that the total fair market value of the
Shares on the date hereof is per Share, or an aggregate of _____________ for
____________ shares.

3.       COMPANY REPURCHASE OPTION.

In addition to all other restrictions imposed by this Agreement or applicable
caw, the Shares acquired by the Purchaser pursuant to this Agreement shall be
subject to the following restrictions and repurchase options.

3.1.     VESTING SCHEDULE.

Vesting will be measured from (the "Vesting Measurement Date"). The Shares
acquired hereunder shall vest and become "Vested Shares" in accordance with the
following vesting schedule:

<TABLE>
<CAPTION>
On or After:...................................................................................Shares Vested As To:
-----------                                                                                    -------------------

<S>                                                                                             <C>
The first anniversary of Vesting Measurement Date:..............................................____% of the Shares

Last day of each calendar month after such first anniversary....................................____% of the Shares

</TABLE>

The vesting schedule of this Agreement would result, assuming Continuous Service
shall have theretofore not terminated, in One Hundred Percent (100%) of the
Restricted Shares being Vested Shares at the end of the calendar month in which
the ______ anniversary of the Vesting Measurement Date falls. Shares which have
not yet become vested are herein called "Unvested Shares." In the event the
Continuous Service of the Purchaser ceases (the "Service Termination Date"), all
vesting shall cease unless otherwise determined by the Board of Directors. As
used herein, the term "Continuous Service" has the meaning given in the Plan.

In the event of a Change in Control of the Company, the Administrator in its
discretion may take one or more of the following actions with respect to the
Shares (whether Vested Shares or Unvested Shares):

     (a) provide for the purchase or exchange of any Vested Shares for an amount
         of cash or other property having a value equal to the value of the cash
         or other property that the Purchaser would have received pursuant to
         such Change in Control transaction in exchange for the Vested Shares
         and provide for the repurchase by the Company of Unvested Shares at the
         repurchase price provided in this Agreement,

     (b) adjust the terms of this Agreement in a manner determined by the
         Administrator to reflect the Change in Control,

     (c) cause this Agreement to be assumed, or new rights substituted therefor,
         by another entity, through the continuance of the Plan and the
         assumption of this Agreement, or the substitution for this Agreement of
         a new agreement of comparable value covering shares of a successor or
         parent corporation, with appropriate adjustments as to the number and
         kind of shares, in which event the Plan and this Agreement, or the new
         agreement substituted therefor, shall continue in the manner and under
         the terms so provided, or

     (d) make such other provision as the Administrator may consider equitable.

If the Administrator does not take any of the forgoing actions, this Agreement
shall terminate upon the consummation of the Change in Control and the
Administrator shall cause written notice of the proposed transaction to be given
to the Purchaser not less than fifteen (15) days prior to the anticipated
effective date of the proposed transaction.

3.2. COMPANY OPTION TO REPURCHASE SHARES FOLLOWING TERMINATION OF CONTINUOUS
     SERVICE.

Concurrent with the Service Termination Date and for the period and under the
procedures set forth in Section 3.3 below, the Company shall have the option to
repurchase (the "Repurchase Option") all or any portion of the Purchaser's
Unvested Shares on the terms and subject to the limitations set forth herein.

3.3.     PROCEDURES FOR EXERCISE OF REPURCHASE OPTION.

For sixty (60) days after the Service Termination Date or other event described
in this Section 3, the Company may exercise its Repurchase Option by giving
Purchaser and/or any other person obligated to sell written notice of the number
of Shares that the Company desires to purchase. The Company shall pay for such
Shares by the delivery of its check in the aggregate amount of the repurchase
price determined pursuant to Section 3.5 below against delivery

                                       2
<PAGE>

of the certificate(s) representing the Shares.

3.4.     DEPOSIT OF SHARES.

In aid of the repurchase provisions set forth herein, Purchaser shall,
immediately upon receipt of the certificate or certificates representing the
Shares, deposit the certificate or certificates, together with a stock power or
other instrument of transfer appropriately endorsed in blank, with the Company
as escrow holder of the certificate(s). Upon Shares becoming Vested Shares, and
in the event that the repurchase rights with respect to any Shares are not
exercised by the Company following any Service Termination Date, the Company
shall cause the certificate or certificates representing such Shares to be
delivered into the possession of Purchaser.

3.5.     REPURCHASE PRICE.

The per share price for the Unvested Shares ("Unvested Stock Repurchase Price")
repurchased by the Company pursuant to this Section 3 shall be an amount equal
to the per share purchase price paid for the Shares by the Purchaser pursuant to
Section 1 above.

3.6.     REPURCHASE IN THE EVENT OF PERSONAL BANKRUPTCY.

If the Purchaser:

     (a)  files a voluntary petition under any bankruptcy or insolvency law or a
          petition for the appointment of a receiver or makes an assignment for
          the benefit of creditors;

     (b)  is subjected involuntarily to such a petition or assignment or to an
          attachment or other legal or equitable interest with respect to the
          Shares and such involuntary petition or assignment or attachment is
          not discharged within sixty (60) days after its date; or

     (c)  is required to transfer the Shares by operation of law or by order or
          decree of any court,

then the Company shall have the option to exercise the Repurchase Right,
exercisable at any time during the period of 60 days after receiving notice
thereof, to purchase all of the Unvested Shares owned by the Purchaser upon the
terms set forth in this Section 3, whether or not the Continuous Service of the
Purchaser has terminated.

3.7.     ASSIGNMENT OF RIGHTS.

The Company may assign its rights under this Section 3 and Section 4.

4.       BREACH AND NON-COMPETITION.

The Administrator may cancel, rescind, suspend, withhold or otherwise limit or
restrict any Shares or rights of Purchaser under this Agreement at any time if
the Purchaser engages in any "Adverse Activity." For purposes of this Section 5,
"Adverse Activity" shall include: (i) the rendering of services for any
organization or engaging directly or indirectly in any business which is or
becomes competitive with the Company, or which organization or business, or the
rendering of services to such organization or business, is or becomes otherwise
prejudicial to or in conflict with the interests of the Company; (ii) the
disclosure to anyone outside the Company, or the use in other than the Company's
business, without prior written authorization from the Company, of any
confidential information or material relating to the business of the Company,
acquired by Purchaser either during or after employment with the Company; (iii)
the failure or refusal to disclose promptly and to assign to the Company, all
right, title and interest in any invention or idea, patentable or not, made or
conceived by Purchaser during employment by the Company, relating in any manner
to the actual or anticipated business, research or development work of the
Company; (iv) activity that results in termination of Purchaser's employment for
"cause," defined here to mean those acts identified in Section 2924 of the
California Labor Code; (v) any material violation of any terms or provisions of
this Agreement; or (vi) any attempt directly or indirectly to induce any
employee of the Company to be employed or perform services elsewhere or any
attempt directly or indirectly to solicit the trade or business of any current
or prospective customer, supplier or partner of the Company. At the request of
the Administrator, the Purchaser shall certify in a manner acceptable to the
Company that he or she is in compliance with the terms and conditions of this
Section 5. In the event Purchaser engages in Adverse Activity prior to, or
during the six (6) months after, any exercise, payment or delivery pursuant to
an Option Agreement, such exercise, payment or delivery may be rescinded at the
sole election of the Company within two years thereafter. In the event of any
such rescission, the Purchaser shall pay to the Company the amount of any gain
realized or payment received as a result of the

                                       3
<PAGE>

disposition of Shares, in such manner and on such terms and conditions as may be
required, and the Company shall be entitled to set-off against the amount of any
such gain any amount owed to the Purchaser by the Company.

5.       RECAPITALIZATION.

In the event that, as the result of a stock split or stock dividend or
combination of shares or any other change, or exchange for other securities, by
reclassification, or recapitalization of the Shares, Purchaser shall be entitled
to new or additional or different shares of stock or securities, the certificate
or certificates for, or other evidences of, such new or additional or different
shares or securities shall be imprinted with the legend(s) provided in Section
6, and shall be deposited with the Company as escrow holder under the terms and
conditions provided in Section 3.4 herein, together with a stock power or other
instrument or transfer appropriately endorsed. In such event, any and all new,
substituted or additional securities or other property (other than cash) to
which the Purchaser is entitled by reason of his ownership of the Shares shall
be immediately subject to the Repurchase Right and First Right of Refusal and be
included in the word "Shares" for all purposes of the Repurchase Right and First
Right of Refusal with the same force and effect as the Shares subject to the
Repurchase Right and the First Right of Refusal under the terms of Section 3 and
Section 4. While the total Vested Stock Repurchase Price and Unvested Stock
Repurchase Price shall remain the same after each such event, the per share
price shall be appropriately adjusted. Shares acquired as provided in this
Section 6 shall be deemed to have been acquired at the time of acquisition of
the Shares on which such Shares were distributed.

6.       RESTRICTIVE LEGENDS.

In addition to all other legends that the Company or its legal counsel consider
appropriate under applicable securities laws, the certificates representing any
Shares, whether Vested Shares or Unvested Shares, purchased pursuant to this
Agreement shall bear substantially the following legend:

          ISSUEE OF SUCH SECURITIES MAY BE REQUIRED TO PROVIDE APPROPRIATE
          INVESTMENT REPRESENTATIONS PRIOR TO ANY SUCH TRANSFER OR ISSUANCE.
--------------------------------------------------------------------------------

Until such time as the Company's Repurchase Rights terminate pursuant to Section
3.6, the stock certificates for the Shares purchased pursuant to this Agreement

7.       STOP-TRANSFER NOTICES.

Purchaser understands and agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate
"stop-transfer" instructions to its transfer agent, if any, and that, if the
Company transfers its own securities, it may make appropriate notations to the
same effect in its own records.

8.       REPRESENTATIONS AND WARRANTIES OF PURCHASER.

The Purchaser warrants and represents to the Company as follows:

     (a) The Purchaser is purchasing the Shares solely for the Purchaser's own
         account for investment and not with a view to or for sale or
         distribution of the Shares or any portion thereof and not with any
         present intention of selling, offering to sell or otherwise disposing
         of or distributing the Shares or any portion thereof. The Purchaser
         also represents that the entire legal and beneficial interest of the
         Shares the Purchaser is purchasing is being purchased for, and will be
         held for the account of, the Purchaser only and neither in whole nor in
         part for any other person.

     (b) The Purchaser has heretofore discussed the Company and its plans,
         operations and financial condition with its officers, has heretofore
         received all such information as the Purchaser deems necessary and
         appropriate to enable the Purchaser to evaluate the financial risk
         inherent in making an investment in the Shares of the Company, and has
         received satisfactory and complete information concerning the business
         and financial condition of the Company in response to all inquiries in
         respect thereof.

     (c) The Purchaser realizes that the purchase of the Shares will be a highly
         speculative investment.

     (d) The Purchaser is able, without impairing the Purchaser's financial
         condition, to hold the Shares for an indefinite period of time and to
         suffer a complete loss on the investment.

     (e) The Purchaser acknowledges that he is aware that the Shares to be
         issued to him by the Company pursuant to this Agreement have not been
         registered under the Act. The Purchaser hereby acknowledges that:

         (i)  the Shares must be held indefinitely unless a transfer of them is
              subsequently registered under the Act or an exemption from such
              registration is available;

         (ii) the share certificate(s) representing the Shares will be stamped
              with the legends restricting transfer as specified in this
              Agreement; and

         (iii) the Company will make a notation in its records of the
              aforementioned restrictions on transfer and legends.

     (f)  The Purchaser understands that the Shares are restricted securities
          within the meaning of Rule 144 promulgated under the Act; that the
          exemption from registration under Rule 144 will not be available in
          any event for at least one year from the date of sale of the Shares to
          the Purchaser, and even then will not be available unless (i) a public
          trading market then exists for the Shares of the Company, (ii)
          adequate current public information concerning the Company is then
          available to the public, (iii) the Purchaser has been the beneficial
          owner and the Purchaser has paid the full purchase price for the
          Shares at least one year prior to the sale, and (iv) other terms and
          conditions of Rule 144 are complied with; and that any sale of the
          Shares may be made by it only in limited amounts in accordance with
          such terms and conditions of Rule 144, as amended from time to time.

                                       5
<PAGE>

     (g)  Without in any way limiting any of the other provisions of this
          Agreement, the Purchaser further agrees that the Purchaser shall in no
          event make any disposition of all or any portion of the Shares which
          the Purchaser is purchasing unless and until:

         (i)  there is then in effect a Registration Statement under the Act
              covering such proposed disposition and such disposition is made in
              accordance with said Registration Statement; or

         (ii) (A) the Purchaser shall have notified the Company of the proposed
              disposition and shall have furnished the Company with a detailed
              statement of the circumstances surrounding the proposed
              disposition, (B) the Purchaser shall have furnished the Company
              with an opinion of counsel to the effect that such disposition
              will not require registration of such shares under the Act, and
              (C) such opinion of counsel shall have been concurred in by
              counsel for the Company and the Company shall have advised the
              Purchaser of such concurrence.

     (h) The Purchaser represents and warrants that he or she has not engaged in
         any Adverse Activity as defined in Section 5.

     (i) The Purchaser acknowledges that the Purchaser has been furnished with a
         copy of the Plan, has read the Plan and this Agreement, and understands
         that all rights and obligations connected with this Agreement are set
         forth in this Agreement and in the Plan.

9.       UNAUTHORIZED TRANSFERS.

The Company shall not be required (a) to transfer on its books any Shares of the
Company which shall have been sold or transferred in violation of any of the
provisions set forth in this Agreement or (b) to treat as owner of such shares
or to accord the right to vote as such owner or to pay dividends to any
transferee to whom such shares shall have been so transferred. In the event of a
sale of Shares by the Purchaser pursuant to Section 4, the Purchaser shall
furnish to the Company proof that such sale was made in compliance with the
provisions of Section 4 as to price and general terms of such sale.
Notwithstanding any other provision of this Agreement, if the Company is an
electing small business corporation under Subchapter S of the Code, at the time
Purchaser seeks to transfer his or her Shares, (a) no transfer shall be
effective unless the transferee covenants to comply with any rules and
regulations of the Internal Revenue Service then in effect relating to the
Company's Subchapter S election and to take no action which will jeopardize such
election; and (b) Purchaser hereby agrees that he or she will not transfer or
attempt to transfer any Shares to any transferee whose ownership of the Shares
could automatically invalidate the Company's Subchapter S election and that such
a sale or transfer shall be void and ineffectual.

10.      "MARKET STAND-OFF" AGREEMENT.

Purchaser agrees that, if requested by the Company or the managing underwriter
of any proposed Public Offering of the Company's securities, Purchaser will not
sell or otherwise transfer or dispose of any Shares held by Purchaser without
the prior written consent of the Company or such underwriter, as the case may
be, during such period of time, not to exceed 180 days following the effective
date of the registration statement filed by the Company with respect to such
Public Offering, as the Company or the underwriter may specify.

11.      ENTIRE AGREEMENT.

This Agreement and the Plan constitutes the entire agreement between the parties
pertaining to its subject matter and supersedes all contemporaneous written or
oral agreements and understandings of the parties, either express or implied.
The parties agree to execute such further instruments and to take such further
action as may reasonably be necessary to carry out the intent of this Agreement.

12.  NO CREATION OR ENLARGEMENT OF PARTICIPANT'S RIGHTS TO CONTINUE IN ANY
     CAPACITY.

The right of the Company and any Affiliated Company (as defined in the Plan) to
terminate at will the Purchaser's services to the Company or any Affiliated
Company at any time (whether by dismissal, discharge or otherwise), with or
without cause, is specifically reserved. Nothing in this Agreement shall
diminish or impair in any manner

                                       6
<PAGE>

whatsoever the right or power of the Company or any Affiliated Company to
terminate the Purchaser's Continuous Service for any reason, with or without
cause.

13.      NOTICES.

Any notice, demand or request required or permitted to be given under this
Agreement shall be in writing and shall be deemed given when delivered

          Company under the Restricted Stock Purchase Agreement or any statute
          or rule of law. Any forbearance or failure or delay by the Company in
          exercising any right, power or remedy hereunder shall not be deemed to
          be a waiver of such right, power or remedy, nor shall any single or
          partial exercise of any right, power or remedy preclude the further
          exercise thereof.

     8.   The Board of Directors may demand and receive payment or additional
          security if for any reason the collateral hereunder is insufficient to
          meet minimum requirements established under federal or state
          securities or banking regulations or as may be necessary to bring the
          Note and the security into compliance with any such law or
          regulations. Any failure of Purchaser to meet any such demand shall be
          deemed a default under this Pledge Agreement and under the note
