3.   TERM OF THE PLAN

     Unless the Plan shall have been earlier terminated by the Board, Awards may
be granted under this Plan at any time in the period commencing on the date of
approval of the Plan by the Board and ending immediately prior to the tenth
anniversary of the earlier of the adoption of the Plan by the Board or approval
of the Plan by the Company's stockholders. Awards granted pursuant to the Plan
within that period shall not expire solely by reason of the termination of the
Plan. Awards of Incentive Options granted prior to stockholder approval of the
Plan are expressly conditioned upon such approval, but in the event of the
failure of the stockholders to approve the Plan shall thereafter and for all
purposes be deemed to constitute Nonstatutory Options.

4.   STOCK SUBJECT TO THE PLAN

     At no time shall the number of shares of Stock issued pursuant to or
subject to outstanding Awards granted under the Plan (including pursuant to
Incentive Options), nor the number of shares of Stock issued pursuant to
Incentive Options, exceed 300,000 shares of Stock; SUBJECT, HOWEVER, to the
provisions of Section 8 of the Plan. For purposes of applying the foregoing
limitation, (a) if any Option expires, terminates, or is cancelled for any
reason without having been exercised in full, the shares not purchased by the
Optionee or which are forfeited by the recipient shall again be available for
Awards to be granted under the Plan and (b) if any Option is exercised by
delivering previously owned shares in payment of the exercise price therefor,
only the net number of shares, that is, the number of shares issued minus the
number received by the Company in payment of the exercise price, shall be
considered to have been issued pursuant to an Award granted under the Plan. In
addition, settlement of any Award shall not count against the foregoing
limitations except to the extent settled in the form of Stock.

                                      -4-

5.   ADMINISTRATION

     The Plan shall be administered by the Committee; PROVIDED, HOWEVER, that at
any time and on any one or more occasions the Board may itself exercise any of
the powers and responsibilities assigned the Committee under the Plan and when
so acting shall have the benefit of all of the provisions of the Plan pertaining
to the Committee's exercise of its authorities hereunder. Subject to the
provisions of the Plan, the Committee shall have complete authority, in its
discretion, to make or to select the manner of making all determinations with
respect to each Award to be granted by the Company under the Plan including the
employee, consultant or director to receive the Award and the form of Award. In
making such determinations, the Committee may take into account the nature of
the services rendered by the respective employees, consultants, and directors,
their present and potential contributions to the success of the Company and its
Affiliates, and such other factors as the Committee in its discretion shall deem
relevant. Subject to the provisions of the Plan, the Committee shall also have
complete authority to interpret the Plan, to prescribe, amend and rescind rules
and regulations relating to it, to determine the terms and provisions of the
respective Award Agreements (which need not be identical), and to make all other
determinations necessary or advisable for the administration of the Plan. The
Committee's determinations made in good faith on matters referred to in the Plan
shall be final, binding and conclusive on all persons having or claiming any
interest under the Plan or an Award made pursuant hereto.

6.   AUTHORIZATION OF GRANTS

     6.1. Eligibility. The Committee may grant from time to time and at any time
prior to the termination of the Plan one or more Awards, either alone or in
combination with any other Awards, to any employee of or consultant to one or
more of the Company and its subsidiary of the Company or to non-employee member
of the Board or of any board of directors (or similar governing authority) of
any subsidiary of the Company. However, only employees of the Company, and of
any parent or subsidiary corporations of the Company, as defined in Sections
424(e) and (f), respectively, of the Code, shall be eligible for the grant of an
Incentive Option. Further, in no event shall the number of shares of Stock
covered by Options granted to any one person in any one calendar year exceed
100% of the aggregate number of shares of Stock subject to the Plan.

<PAGE>
                                      -5-

     6.2. General Terms of Awards. Each grant of an Award shall be subject to
all applicable terms and conditions of the Plan (including but not limited to
any specific terms and conditions applicable to that type of Award set out in
the following Section), and such other terms and conditions, not inconsistent
with the terms of the Plan, as the Committee may prescribe. No prospective
Participant shall have any rights with respect to an Award, unless and until
such Participant has executed an agreement evidencing the Award, delivered a
fully executed copy thereof to the Company, and otherwise complied with the
applicable terms and conditions of such Award.

     6.3. Effect of Termination of Employment, Etc. Unless the Committee shall
provide otherwise with respect to any Award, if the Participant's employment or
other association with the Company and its Affiliates ends for any reason,
including because of the Participant's employer ceasing to be an Affiliate, any
outstanding Option of the Participant shall cease to be exercisable in any
respect not later than 90 days following that event and, for the period it
remains exercisable following that event, shall be exercisable only to the
extent exercisable at the date of that event. Military or sick leave or other
bona fide leave shall not be deemed a termination of employment or other
association, PROVIDED that it does not exceed the longer of ninety (90) days or
the period during which the absent Participant's reemployment rights, if any,
are guaranteed by statute or by contract.

     6.4. Non-Transferability of Awards. Except as otherwise provided in this
Section 6.4, Awards shall not be transferable, and no Award or interest therein
may be sold, transferred, pledged, assigned, or otherwise alienated or
hypothecated, other than by will or by the laws of descent and distribution. All
of a Participant's rights in any Award may be exercised during the life of the
Participant only by the Participant or the Participant's legal representative.
However, the Committee may, at or after the grant of an Award of a Nonstatutory
Option provide that such Award may be transferred by the recipient to a family
member; PROVIDED, HOWEVER, that any such transfer is without payment of any
consideration whatsoever and that no transfer shall be valid unless first
approved by the Committee, acting in its sole discretion. For this purpose,
"family member" means any child, stepchild, grandchild, parent, stepparent,
spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law,
son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including
adoptive relationships, any person sharing the employee's household (other than
a tenant or employee), a trust in which the foregoing persons have more than
fifty (50) percent of the beneficial interests, a foundation in which the
foregoing persons (or the Participant) control the management of assets, and any
other entity in which these persons (or the Participant) own more than fifty
(50) percent of the voting interests.

7.   SPECIFIC TERMS OF AWARDS

     7.1. Options.

          (a) Date of Grant. The granting of an Option shall take place at the
time specified in the Award Agreement. Only if expressly so provided in the
applicable Award Agreement shall the Grant Date be the date on which the Award
Agreement shall have been duly executed and delivered by the Company and the
Optionee.

<PAGE>
                                      -6-

          (b) Exercise Price. The price at which shares of Stock may be acquired
under each Incentive Option shall be not less than 100% of the Market Value of
Stock on the Grant Date, or not less than 110% of the Market Value of Stock on
the Grant Date if the Optionee is a Ten Percent Owner. The price at which shares
may be acquired under each Nonstatutory Option shall not be so limited solely by
reason of this Section.

          (c) Option Period. No Incentive Option may be exercised on or after
the tenth anniversary of the Grant Date, or on or after the fifth anniversary of
the Grant Date if the Optionee is a Ten Percent Owner. The Option period under
each Nonstatutory Option shall not be so limited solely by reason of this
Section.

          (d) Exercisability. An Option may be immediately exercisable or become
exercisable in such installments, cumulative or non-cumulative, as the Committee
may determine. In the case of an Option not otherwise immediately exercisable in
full, the Committee may Accelerate such Option in whole or in part at any time;
PROVIDED, HOWEVER, that in the case of an Incentive Option, any such
Acceleration of the Option would not cause the Option to fail to comply with the
provisions of Section 422 of the Code or the Optionee consents to the
Acceleration.

          (e) Method of Exercise. An Option may be exercised by the Optionee
giving written notice, in the manner provided in Section 16, specifying the
number of shares with respect to which the Option is then being exercised. The
notice shall be accompanied by payment in the form of cash, check payable to the
order of the Company or wire transfer in an amount equal to the exercise price
of the shares to be purchased, or, subject in each instance to the Committee's
approval, acting in its sole discretion, and to such conditions, if any, as the
Committee may deem necessary to avoid adverse accounting effects to the Company,
by delivery to the Company of shares of Stock having a Market Value equal to the
exercise price of the shares to be purchased.

If the Stock is traded on an established market, payment of any exercise price
may also be made through and under the terms and conditions of any formal
cashless exercise program authorized by the Company entailing the sale of the
Stock subject to an Option in a brokered transaction (other than to the
Company). Receipt by the Company of such notice and payment in any authorized or
combination of authorized means shall constitute the exercise of the Option.
Within thirty (30) days thereafter but subject to the remaining provisions of
the Plan, the Company shall deliver or cause to be delivered to the Optionee or
his agent a certificate or certificates for the number of shares then being
purchased. Such shares shall be fully paid and nonassessable.

<PAGE>
                                      -7-

          (f) Limit on Incentive Option Characterization. An Incentive Option
shall be considered to be an Incentive Option only to the extent that the number
of shares of Stock for which the Option first becomes exercisable in a calendar
year do not have an aggregate Market Value (as of the date of the grant of the
Option) in excess of the "current limit". The current limit for any Optionee for
any calendar year shall be $100,000 MINUS the aggregate Market Value at the date
of grant of the number of shares of Stock available for purchase for the first
time in the same year under each other Incentive Option previously granted to
the Optionee under the Plan, and under each other incentive stock option
previously granted to the Optionee under any other incentive stock option plan
of the Company and its Affiliates, after December 31, 1986. Any shares of Stock
which would cause the foregoing limit to be violated shall be deemed to have
been granted under a separate Nonstatutory Option, otherwise identical in its
terms to those of the Incentive Option.

          (g) Notification of Disposition. Each person exercising any Incentive
Option granted under the Plan shall be deemed to have covenanted with the
Company to report to the Company any disposition of such shares prior to the
expiration of the holding periods specified by Section 422(a)(1) of the Code
and, if and to the extent that the realization of income in such a disposition
imposes upon the Company federal, state, local or other withholding tax
requirements, or any such withholding is required to secure for the Company an
otherwise available tax deduction, to remit to the Company an amount in cash
sufficient to satisfy those requirements.

     7.2. Awards to Participants Outside the United States. The Committee may
modify the terms of any Award under the Plan granted to a Participant who is, at
the time of grant or during the term of the Award, resident or primarily
employed outside of the United States in any manner deemed by the Committee to
be necessary or appropriate in order that the Award shall conform to laws,
regulations, and customs of the country in which the Participant is then
resident or primarily employed, or so that the value and other benefits of the
Award to the Participant, as affected by foreign tax laws and other restrictions
applicable as a result of the Participant's residence or employment abroad,
shall be comparable to the value of such an Award to a Participant who is
resident or primarily employed in the United States. The Committee may establish
supplements to, or amendments, restatements, or alternative versions of the Plan
for the purpose of granting and administrating any such modified Award. No such
modification, supplement, amendment, restatement or alternative version may
increase the share limit of Section 4.

8.   ADJUSTMENT PROVISIONS

     8.1. Adjustment for Corporate Actions. All of the share numbers set forth
in the Plan reflect the capital structure of the Company as of March 22, 2005.
Subject to Section 8.2, if subsequent to that date the outstanding shares of
Stock (or any other securities covered by the Plan by reason of the prior
application of this Section) are increased, decreased, or exchanged for a
different number or kind of shares or other securities, or if additional shares
or new or different shares or other securities are distributed with respect to
shares of Stock, through merger, consolidation, sale of all or substantially all
the property of the Company, reorganization, recapitalization, reclassification,
stock dividend, stock split, reverse stock split, or other similar distribution
with respect to such shares of Stock, an appropriate and proportionate
adjustment will be made in (i) the maximum numbers and kinds of shares provided
in Section 4, (ii) the numbers and kinds of shares or other securities subject
to the then outstanding Awards, and (iii) the exercise price for each share or
other unit of any other securities subject to then outstanding Options (without
change in the aggregate purchase price as to which such Options remain
exercisable).

<PAGE>
                                      -8-

     8.2. Treatment in Certain Acquisitions. Subject to any provisions of then
outstanding Awards granting greater rights to the holders thereof, in the event
of an Acquisition in which outstanding Awards are not Accelerated in full
pursuant to Section 9, any then outstanding Awards shall nevertheless Accelerate
to the extent not assumed or replaced by comparable Awards referencing shares of
the capital stock of the successor or acquiring entity or parent thereof, and
thereafter (or after a reasonable period following the Acquisition, as
determined by the Committee) terminate. As to any one or more outstanding Awards
which are not otherwise Accelerated in full by reason of such Acquisition, the
Committee may also, either in advance of an Acquisition or at the time thereof
and upon such terms as it may deem appropriate, provide for the Acceleration of
such outstanding Awards in the event that the employment of the Participants
should subsequently terminate following the Acquisition. Each outstanding Award
that is assumed in connection with an Acquisition, or is otherwise to continue
in effect subsequent to the Acquisition, will be appropriately adjusted,
immediately after the Acquisition, as to the number and class of securities and
other relevant terms in accordance with Section 8.1.

     8.3. Dissolution or Liquidation. Upon dissolution or liquidation of the
Company, other than as part of an Acquisition or similar transaction, each
outstanding Option shall terminate, but the Optionee shall have the right,
immediately prior to the dissolution or liquidation, to exercise the Option to
the extent exercisable on the date of dissolution or liquidation.

     8.4. Adjustment of Awards Upon the Occurrence of Certain Unusual or
Nonrecurring Events. In the event of any corporate action not specifically
covered by the preceding Sections, including but not limited to an extraordinary
cash distribution on Stock, a corporate separation or other reorganization or
liquidation, the Committee may make such adjustment of outstanding Awards and
their terms, if any, as it, in its sole discretion, may deem equitable and
appropriate in the circumstances. The Committee may make adjustments in the
terms and conditions of, and the criteria included in, Awards in recognition of
unusual or nonrecurring events (including, without limitation, the events
described in this Section) affecting the Company or the financial statements of
the Company or of changes in applicable laws, regulations, or accounting
principles, whenever the Committee determines that such adjustments are
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan.

<PAGE>
                                      -9-

     8.5. Related Matters. Any adjustment in Awards made pursuant to this
Section 8 shall be determined and made, if at all, by the Committee and shall
include any correlative modification of terms, including of Option exercise
prices, rates of vesting or exercisability so as to ensure the rights of the
Participants in their respective Awards are not substantially diminished nor
enlarged as a result of the adjustment and corporate action other than as
expressly contemplated in this Section 8. No fraction of a share shall be
purchasable or deliverable upon exercise, but in the event any adjustment
hereunder of the number of shares covered by an Award shall cause such number to
include a fraction of a share, such number of shares shall be adjusted to the
nearest smaller whole number of shares.

9.   CHANGE OF CONTROL

     Except as otherwise provided below, upon the occurrence of a Change in
Control, any and all Options not already exercisable in full shall Accelerate
with respect to 100% of the shares for which such Options are not then
exercisable. The foregoing shall not apply in the case of any Award pursuant to
an Award Agreement requiring other or additional terms upon a Change in Control
(or similar event), or if specifically prohibited under applicable laws, or by
the rules and regulations of any governing governmental agencies or national
securities exchanges.

10.  SETTLEMENT OF AWARDS

     10.1. Violation of Law. Notwithstanding any other provision of the Plan or
the relevant Award Agreement, if, at any time, in the reasonable opinion of the
Company, the issuance of shares of Stock covered by an Award may constitute a
violation of law, then the Company may delay such issuance and the delivery of a
certificate for such shares until (i) approval shall have been obtained from
such governmental agencies, other than the Securities and Exchange Commission,
as may be required under any applicable law, rule, or regulation and (ii) in the
case where such issuance would constitute a violation of a law administered by
or a regulation of the Securities and Exchange Commission, one of the following
conditions shall have been satisfied:

          (a) the shares are at the time of the issue of such shares effectively
registered under the Securities Act of 1933; or

          (b) the Company shall have determined, on such basis as it deems
appropriate (including an opinion of counsel in form and substance satisfactory
to the Company) that the sale, transfer, assignment, pledge, encumbrance or
other disposition of such shares or such beneficial interest, as the case may
be, does not require registration under the Securities Act of 1933, as amended
or any applicable State securities laws.

The Company shall make all reasonable efforts to bring about the occurrence of
said events.

     10.2. Corporate Restrictions on Rights in Stock. Any Stock to be issued
pursuant to Awards granted under the Plan shall be subject to all restrictions
upon the transfer thereof which may be now or hereafter imposed by the charter,
certificate or articles, and by-laws, of the Company.

<PAGE>
                                      -10-

     10.3. Investment Representations. The Company shall be under no obligation
to issue any shares covered by any Award unless the shares to be issued pursuant
to Awards granted under the Plan have been effectively registered under the
Securities Act of 1933, as amended, or the Participant shall have made such
written representations to the Company (upon which the Company believes it may
reasonably rely) as the Company may deem necessary or appropriate for purposes
of confirming that the issuance of such shares will be exempt from the
registration requirements of that Act and any applicable state securities laws
and otherwise in compliance with all applicable laws, rules and regulations,
including but not limited to that the Participant is acquiring the shares for
his or her own account for the purpose of investment and not with a view to, or
for sale in connection with, the distribution of any such shares.

     10.4. Registration. If the Company shall deem it necessary or desirable to
register under the Securities Act of 1933, as amended or other applicable
statutes any shares of Stock issued or to be issued pursuant to Awards granted
under the Plan, or to qualify any such shares of Stock for exemption from the
Securities Act of 1933, as amended or other applicable statutes, then the
Company shall take such action at its own expense. The Company may require from
each recipient of an Award, or each holder of shares of Stock acquired pursuant
to the Plan, such information in writing for use in any registration statement,
prospectus, preliminary prospectus or offering circular as is reasonably
necessary for that purpose and may require reasonable indemnity to the Company
and its officers and directors from that holder against all losses, claims,
damage and liabilities arising from use of the information so furnished and
caused by any untrue statement of any material fact therein or caused by the
omission to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in the light of the circumstances
under which they were made. In addition, the Company may require of any such
person that he or she agree that, without the prior written consent of the
Company or the managing underwriter in any public offering of shares of Stock,
he or she will not sell, make any short sale of, loan, grant any option for the
purchase of, pledge or otherwise encumber, or otherwise dispose of, any shares
of Stock during the 180 day period commencing on the effective date of the
registration statement relating to the underwritten public offering of
securities. Without limiting the generality of the foregoing provisions of this
Section 10.5, if in connection with any underwritten public offering of
securities of the Company the managing underwriter of such offering requires
that the Company's directors and officers enter into a lock-up agreement
containing provisions that are more restrictive than the provisions set forth in
the preceding sentence, then (a) each holder of shares of Stock acquired
pursuant to the Plan (regardless of whether such person has complied or complies
with the provisions of clause (b) below) shall be bound by, and shall be deemed
to have agreed to, the same lock-up terms as those to which the Company's
directors and officers are required to adhere; and (b) at the request of the
Company or such managing underwriter, each such person shall execute and deliver
a lock-up agreement in form and substance equivalent to that which is required
to be executed by the Company's directors and officers.

     10.5. Placement of Legends; Stop Orders; etc. Each share of Stock to be
issued pursuant to Awards granted under the Plan may bear a reference to the
investment representation made in accordance with Section 10.4 in addition to
any other applicable restriction under the Plan, the terms of the Award and if
applicable under the Stockholders' Agreement and to the fact that no
registration statement has been filed with the Securities and Exchange
Commission in respect to such shares of Stock. All certificates for shares of
Stock or other securities delivered under the Plan shall be subject to such
stock transfer orders and other restrictions as the Committee may deem advisable
under the rules, regulations, and other requirements of any stock exchange upon
which the Stock is then listed, and any applicable federal or state securities
law, and the Committee may cause a legend or legends to be put on any such
certificates to make appropriate reference to such restrictions.

     10.6. Tax Withholding. Whenever shares of Stock are issued or to be issued
pursuant to Awards granted under the Plan, the Company shall have the right to
require the recipient to remit to the Company an amount sufficient to satisfy
federal, state, local or other withholding tax requirements if, when, and to the
extent required by law (whether so required to secure for the Company an
otherwise available tax deduction or otherwise) prior to the delivery of any
certificate or certificates for such shares. The obligations of the Company
under the Plan shall be conditional on satisfaction of all such withholding
obligations and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
recipient of an Award. However, in such cases Participants may elect, subject to
the approval of the Committee, acting in its sole discretion, to satisfy an
applicable withholding requirement, in whole or in part, by having the Company
withhold shares to satisfy their tax obligations. Participants may only elect to
have Shares withheld having a Market Value on the date the tax is to be
determined equal to the minimum statutory total tax which could be imposed on
the transaction. All elections shall be irrevocable, made in writing, signed by
the Participant, and shall be subject to any restrictions or limitations that
the Committee deems appropriate.

11.  RESERVATION OF STOCK

     The Company shall at all times during the term of the Plan and any
outstanding Awards granted hereunder reserve or otherwise keep available such
number of shares of Stock as will be sufficient to satisfy the requirements of
the Plan (if then in effect) and the Awards and shall pay all fees and expenses
necessarily incurred by the Company in connection therewith.

12.  LIMITATION OF RIGHTS IN STOCK; NO SPECIAL SERVICE RIGHTS

     A Participant shall not be deemed for any purpose to be a stockholder of
the Company with respect to any of the shares of Stock subject to an Award,
unless and until a certificate shall have been issued therefor and delivered to
the Participant or his agent. Nothing contained in the Plan or in any Award
Agreement shall confer upon any recipient of an Award any right with respect to
the continuation of his or her employment or other association with the Company
(or any Affiliate), or interfere in any way with the right of the Company (or
any Affiliate), subject to the terms of any separate employment or consulting
agreement or provision of law or corporate articles or by-laws to the contrary,
at any time to terminate such employment or consulting agreement or to increase
or decrease, or otherwise adjust, the other terms and conditions of the
recipient's employment or other association with the Company and its Affiliates.

13.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan by the Board nor the submission of the
Plan to the stockholders of the Company shall be construed as creating any
limitations on the power of the Board to adopt such other incentive arrangements
as it may deem desirable, including without limitation, the granting of stock
options and restricted stock other than under the Plan, and such arrangements
may be either applicable generally or only in specific cases.

14.  TERMINATION AND AMENDMENT OF THE PLAN

     The Board may at any time terminate the Plan or make such modifications of
the Plan as it shall deem advisable. Unless the Board otherwise expressly
provides, no amendment of the Plan shall affect the terms of any Award
outstanding on the date of such amendment. In any case, no termination or
amendment of the Plan may, without the consent of any recipient of an Award
granted hereunder, adversely affect the rights of the recipient under such
Award.

     The Committee may amend the terms of any Award theretofore granted,
prospectively or retroactively, provided that the Award as amended is consistent
with the terms of the Plan, but no such amendment shall impair the rights of the
recipient of such Award without his or her consent.

15.  NOTICES AND OTHER COMMUNICATIONS

     Any notice, demand, request or other communication hereunder to any party
shall be deemed to be sufficient if contained in a written instrument delivered
in person or duly sent by first class registered, certified or overnight mail,
postage prepaid, or telecopied with a confirmation copy by regular, certified or
overnight mail, addressed or telecopied, as the case may be, (i) if to the
recipient of an Award, at his or her residence address last filed with the
Company and (ii) if to the Company, at its principal place of business,
addressed to the attention of its Treasurer, or to such other address or
telecopier number, as the case may be, as the addressee may have designated by
notice to the addressor. All such notices, requests, demands and other
communications shall be deemed to have been received: (i) in the case of
personal delivery, on the date of such delivery; (ii) in the case of mailing,
when received by the addressee; and (iii) in the case of facsimile transmission,
when confirmed by facsimile machine report.

16.  GOVERNING LAW

     The Plan and all Award Agreements and actions taken thereunder shall be
governed, interpreted and enforced in accordance with the laws of the
California, without regard to the conflict of laws principles thereof.<PAGE>
                                                                   Exhibit 10.15

                               AMISTAR CORPORATION
                        INCENTIVE STOCK OPTION AGREEMENT

     THIS AGREEMENT is entered into this <<day>><<dayth>> day of
<<month>>, <<year>>, by and between Amistar Corporation (the "Company"), a
California corporation, and <<FirstName>> <<LastName>> (the "Optionee") pursuant
to the Company's 1994 Employee Stock Option Plan dated February 28, 1994 (the
"Plan").

     In consideration of the covenants herein set forth, and pursuant to
authorization by the Board of Directors of the Company, the parties agree as
follows:

     1. Option; Number of Shares; Price.
        --------------------------------

     The Company grants to the Optionee the right ("Option") to purchase all or
any portion of <<shares>> shares of the Common Stock of the Company ("Stock") at
a purchase price of $<<price>> per share (the "Option Price"), which price has
been determined to be not less than the fair market value of the Stock per share
on the date of this Agreement; provided, however, that if the Optionee is a
10-percent shareholder of the Company as defined in Section 422(b)(6) of the
Internal Revenue Code of 1954, as amended (the "Code"), at the time the Option
is granted the Option Price shall be not less than 110 percent of such fair
market value. This Option is subject to the terms and conditions stated in this
Agreement and in the Plan, including but not limited to the provisions of
Section 12 of the Plan under which this Option shall be subject to modification
when certain events occur. It is intended that this Option will qualify for
treatment as an incentive stock option under Section 422A of the Code.

     2. Terms of Agreement
        ------------------

     This Agreement shall expire when the first of the following occurs:

          (a) the expiration of five years from the date of this Agreement,
provided, however, that if the Optionee is a 10 percent shareholder of the
Company as defined in Section 422A(b)(6) of the Code, the expiration of five
years from the date of this Agreement;

          (b) the date and time of the termination of the Optionee's employment
by the Company, except that with respect to any installment of the Option which
is exercisable under Section 3(b) hereof upon the date of such termination, this
Agreement will expire on the expiration of three months from the date of the
Optionee's termination of employment (other than by reason of death), except
that if the Optionee is then disabled (within the meaning of Section 105(d)(4)
of the Code), the expiration of one year from the date of the Optionee's
termination of employment;

          (c) the expiration of one year from the date the Optionee dies if he
dies while he is, or not later than three months after he has ceased to be,
employed by the Company or any of its subsidiaries (as such term is used in the
Plan) in a capacity in which he would be eligible to receive grants of Options
under the Plan; or

          (d) the termination of the Option under Section 15 of the Plan.

        ------------------

     This Option may be exercised by the Optionee (or, after his death, by the
person designated in Section 4 hereof) only in accordance with the following
provisions:

          (a) this Option may be exercised by the Optionee upon delivery of the
following to the Company at its principal executive offices:

               (i) a written notice of exercise which identifies this agreement
and states the number (which may not be less than 100) of shares of stock then
being purchased;

               (ii) a check or cash in the amount of the purchase price (or
payment of the purchase price in such other form of lawful consideration as the
Company's Board of Directors may approve from time to time under the provisions
of Section 7 of the Plan);

               (iii) a letter of agreement, if requested by the Company, in such
form and substance as the Company may require, setting forth the investment
intent of the Optionee and such other agreements and representations as
described in Section 10 of the Plan; and

               (iv) a check or cash, if requested by the Company either before
or after the Company's receipt of the notice of exercise, in the amount of any
taxes (other than stock issue or transfer taxes) which the Company is obligated
to collect or withhold by reason of exercise of this Option.

                                       3
<PAGE>

          (b) This Option shall become exercisable in the following
installments. The Optionee shall be entitled to purchase all or any portion of
the shares of Stock indicated opposite the dates set forth below on or after
such dates, provided that the Optionee is employed by the Company on such date:

                    Date                            No. of Shares
                    ----                            -------------
            <<day>> <<month>>, 2005                  <<quarter>>
            <<day>> <<month>>, 2006                  <<quarter>>
            <<day>> <<month>>, 2007                  <<quarter>>
            <<day>> <<month>>, 2008                  <<quarter>>

The installments shall be cumulative, such that this Option may be exercised as
to any or all of the Stock covered by an installment at any time or times after
the installment becomes exercisable and until this Option expires or terminates.
The termination of the employment of the Optionee by death, disability or
otherwise shall not accelerate or otherwise affect the number of shares with
respect to which this Option may be exercised except as provided for in the
foregoing schedule.

     4. Death of Optionee; No Assignment
        --------------------------------

     The rights of the Optionee under this Agreement may not be assigned or
transferred except by will or by the laws of descent and distribution. This
Option shall be exercisable only by the Optionee during his lifetime. Any
attempt to assign this Option in contravention of this Agreement shall be void
and shall have no effect. If the Optionee should die while he is, or not later
than three months after he has ceased to be, employed by the Company or a
subsidiary, his legal representative, his legatee, or the person who acquired
the right to exercise this Option by reason of the death of the Optionee (this
group shall be collectively known as "Successors") succeeds to the Optionee's
rights under this Agreement. After the death of the Optionee, only his Successor
may execute this Option.

<PAGE>

     5. Employment of Optionee
        ----------------------

     The Optionee agrees to remain in the employ of the Company or a subsidiary
for a period of one year from the date of this Agreement if such continued
employment is requested by such employer. This provision shall not obligate the
Company or a subsidiary to employ the Optionee for that period or for any other
period.

     6. No Rights as Shareholders
        -------------------------

     The Optionee shall have no rights as a shareholder of any shares of Stock
covered by this Option until the date (the "Exercise Date") an entry evidencing
such ownership is made in the stock transfer books of the Company. Except as may
be provided under Section 12 of the Plan, the Company will make no adjustment
for dividends (ordinary or extraordinary, whether in cash, securities, or other
property) or distributions or other rights for which the record date is prior to
the Exercise Date.

     7. Representations and Warranties of Optionee
        ------------------------------------------

     Optionee represents and warrants that the Option is being acquired by the
Optionee in good faith for THE OPTIONEE'S own personal account, for investment
purposes only, and not with a view to the distribution, resale or other
disposition thereof. Optionee agrees that he will exercise the Option without
any then present intent to sell or otherwise dispose of all or any part of the
Stock acquired thereby.

                                       5
<PAGE>

     Optionee acknowledges that the Company may issue Stock upon the exercise of
the Option without registering such Stock under the Securities Act of 1933, as
amended (the "Act") on the basis of certain alternative exemptions from such
registration requirement. Accordingly, the Optionee agrees that his exercise of
the Option may be expressly conditioned upon his delivery to the Company of an
investment certificate including such representations and undertakings as the
Company may reasonably require in order to assure the availability of such
exemptions, including a representation that the Optionee is acquiring the Stock
for investment and not with a present intention of selling or otherwise
disposing thereof and an agreement by the Optionee that the shares evidencing
the Stock may bear a legend indicating such non-registration under the Act and
the resulting restrictions on transfer. The Optionee acknowledges that, because
Stock received upon exercise of an Option may be unregistered, the Optionee may
be required to hold the Stock indefinitely unless it is subsequently registered
for resale under the Act or an exemption from such registration is available.

     8. This Agreement Subject To Plan
        ------------------------------

     This Agreement is made under the provisions of the Plan and shall be
interpreted in a manner consistent with it. Any provision in this Agreement
inconsistent with the Plan shall be superseded and governed by the Plan. A copy
of the Plan is available to the Optionee at the Company's principal executive
offices upon request and without charge.

                                       6
<PAGE>

     9. Legends on Certificates.
        ------------------------

     Optionee acknowledges that the certificates representing the Stock issued
upon exercise of the Option may bear such legends and be subject to such
restrictions on transfer as the Company may reasonably deem necessary to comply
with all applicable state and federal securities laws and regulations and to
satisfy any requirements under a Stock Restriction Agreement pursuant to which
such Stock is issued.

     The Company and the Optionee have executed this Agreement as of the date
set forth in the first paragraph.
