Section 4. Shares Available for Awards.

            (a) Shares Available. Subject to adjustment as provided in Section
4(c) of the Plan, the aggregate number of Shares that may be issued under all
Awards under the Plan shall be 850,000. Shares to be issued under the Plan may
be either authorized but unissued Shares or Shares acquired in the open market
or otherwise. Any Shares that are used by a Participant as full or partial
payment to the Company of the purchase price relating to an Award, or in
connection with the satisfaction of tax obligations relating to an Award, shall
again be available for granting Awards (other than Incentive Stock Options)
under the Plan. In addition, if any Shares covered by an Award or to which an
Award relates are not purchased or are forfeited, or if an Award otherwise
terminates without delivery of any Shares, then the number of Shares counted
against the aggregate number of Shares available under the Plan with respect to
such Award, to the extent of any such forfeiture or termination, shall again be
available for granting Awards under the Plan. Notwithstanding the foregoing, the
number of Shares available for granting Incentive Stock Options under the Plan
shall not exceed 850,000, subject to adjustment as provided in the Plan and
subject to the provisions of Section 422 or 424 of the Code or any successor
provision.

            (b) Accounting for Awards. For purposes of this Section 4, if an
Award entitles the holder thereof to receive or purchase Shares, the number of
Shares covered by such Award or to which such Award relates shall be counted on
the date of grant of such Award against the aggregate number of Shares available
for granting Awards under the Plan.

            (c) Adjustments. In the event that the Committee shall determine
that any dividend or other distribution (whether in the form of cash, Shares,
other securities or other property), recapitalization, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or other property) that
thereafter may be made the subject of Awards, (ii) the number and type of Shares
(or other securities or other property) subject to outstanding Awards and (iii)
the purchase or exercise price with respect to any Award; provided, however,
that the number of Shares covered by any Award or to which such Award relates
shall always be a whole number.

                                      -4-

Section 5. Eligibility.

      Any Eligible Person shall be eligible to be designated a Participant. In
determining which Eligible Persons shall receive an Award and the terms of any
Award, the Committee may take into account the nature of the services rendered
by the respective Eligible Persons, their present and potential contributions to
the success of the Company or such other factors as the Committee, in its
discretion, shall deem relevant. Notwithstanding the foregoing, an Incentive
Stock Option may only be granted to full or part-time employees (which term as
used herein includes, without limitation, officers and Directors who are also
employees), and an Incentive Stock Option shall not be granted to an employee of
an Affiliate unless such Affiliate is also a "subsidiary corporation" of the
Company within the meaning of Section 424(f) of the Code or any successor
provision.

Section 6. Awards.

            (a) Options. The Committee is hereby authorized to grant Options to
Participants with the following terms and conditions and with such additional
terms and conditions not inconsistent with the provisions of the Plan as the
Committee shall determine:

                  (i) Exercise Price. The purchase price per Share purchasable
under an Option shall be determined by the Committee; provided, however, that
such purchase price for an Incentive Stock Option shall not be less than 100% of
the Fair Market Value of a Share on the date of grant of such Option; further
provided, however, that in the event the Participant is an Employee and owns
stock representing more than 10% of the total combined voting power of all
classes of stock of the Company or any parent and subsidiary corporations
immediately before the grant, the purchase price for an Incentive Stock Option
shall not be less than 110% of the Fair Market Value of a Share on the date of
grant of such Option.

                  (ii) Option Term. The term of each Option shall be fixed by
the Committee; provided, however, that the term of a Option shall not exceed ten
years from the date of grant, and an Option may only be exercised only during
such term.

                  (iii) Time and Method of Exercise. The Committee shall
determine the time or times at which an Option may be exercised in whole or in
part and the method or methods by which, and the form or forms (including,
without limitation, cash, Shares, promissory notes, other securities, other
Awards or other property, or any combination thereof, having a Fair Market Value
on the exercise date equal to the relevant exercise price) in which, payment of
the exercise price with respect thereto may be made or deemed to have been made.

                  (iv) Reload Options. The Committee may grant Reload Options,
separately or together with another Option, pursuant to which, subject to the
terms and conditions established by the Committee, the Participant would be
granted a new Option when the payment of the exercise price of a previously
granted option is made by the delivery of Shares owned by the Participant
pursuant to Section 6(a)(iii) of the Plan or the relevant provisions of another
plan of the Company, and/or when Shares are tendered or withheld as payment of
the amount to be withheld under applicable income tax laws in connection with

                                      -5-
<PAGE>

the exercise of an Option, which new Option would be an Option to purchase the
number of Shares not exceeding the sum of (A) the number of Shares so provided
as consideration upon the exercise of the previously granted option to which
such Reload Option relates and (B) the number of Shares, if any, tendered or
withheld as payment of the amount to be withheld under applicable tax laws in
connection with the exercise of the option to which such Reload Option relates
pursuant to the relevant provisions of the plan or agreement relating to such
option. Reload Options may be granted with respect to Options previously granted
under the Plan or any other stock option plan of the Company or may be granted
in connection with any Option granted under the Plan or any other stock option
plan of the Company at the time of such grant. Such Reload Options shall have a
per share exercise price equal to the Fair Market Value of one Share as of the
date of grant of the new Option. Any Reload Option shall be subject to
availability of sufficient Shares for grant under the Plan.

            (b) Stock Appreciation Rights. The Committee is hereby authorized to
grant Stock Appreciation Rights to Participants subject to the terms of the Plan
and any applicable Award Agreement. A Stock Appreciation Right granted under the
Plan shall confer on the holder thereof a right to receive upon exercise thereof
the excess of (i) the Fair Market Value of one Share on the date of exercise
(or, if the Committee shall so determine, at any time during a specified period
before or after the date of exercise) over (ii) the grant price of the Stock
Appreciation Right as specified by the Committee, which price shall not be less
than 100% of the Fair Market Value of one Share on the date of grant of the
Stock Appreciation Right. Subject to the terms of the Plan and any applicable
Award Agreement, the grant price, term, methods of exercise, dates of exercise,
methods of settlement and any other terms and conditions of any Stock
Appreciation Right shall be as determined by the Committee. The Committee may
impose such conditions or restrictions on the exercise of any Stock Appreciation
Right as it may deem appropriate.

            (c) Restricted Stock and Restricted Stock Units. The Committee is
hereby authorized to grant Restricted Stock and Restricted Stock Units to
Participants with the following terms and conditions and with such additional
terms and conditions not inconsistent with the provisions of the Plan as the
Committee shall determine:

                  (i) Restrictions. Shares of Restricted Stock and Restricted
Stock Units shall be subject to such restrictions as the Committee may impose
(including, without limitation, a waiver by the Participant of the right to vote
or to receive any dividend or other right or property with respect thereto),
which restrictions may lapse separately or in combination at such time or times,
in such installments or otherwise as the Committee may deem appropriate.

                  (ii) Stock Certificates. Any Restricted Stock granted under
the Plan shall be registered in the name of the Participant and shall bear an
appropriate legend referring to the terms, conditions and restrictions
applicable to such Restricted Stock. In the case of Restricted Stock Units, no
Shares shall be issued at the time such Awards are granted.

                  (iii) Forfeiture. Except as otherwise determined by the
Committee, upon termination of employment (as determined under criteria
established by the Committee) during the applicable restriction period, all
Shares of Restricted Stock and all Restricted Stock Units at such time subject
to restriction shall be forfeited and reacquired by the Company; provided,
however, that the Committee may, when it finds that a waiver would be in the
best interest of the Company, waive in whole or in part any or all remaining
restrictions with respect to Shares of Restricted Stock or Restricted Stock
Units. Upon the lapse or waiver of restrictions and the restricted period
relating to Restricted Stock Units evidencing the right to receive Shares, such
Shares shall be issued and delivered to the holders of the Restricted Stock
Units.

                                      -6-
<PAGE>

            (d) Performance Awards. The Committee is hereby authorized to grant
Performance Awards to Participants subject to the terms of the Plan and any
applicable Award Agreement. A Performance Award granted under the Plan (i) may
be denominated or payable in cash, Shares (including, without limitation,
Restricted Stock and Restricted Stock Units), other securities, other Awards or
other property and (ii) shall confer on the holder thereof the right to receive
payments, in whole or in part, upon the achievement of such performance goals
during such performance periods as the Committee shall establish. Subject to the
terms of the Plan and any applicable Award Agreement, the performance goals to
be achieved during any performance period, the length of any performance period,
the amount of any Performance Award granted, the amount of any payment or
transfer to be made pursuant to any Performance Award and any other terms and
conditions of any Performance Award shall be determined by the Committee.

            (e) Other Stock Grants. The Committee is hereby authorized, subject
to the terms of the Plan and any applicable Award Agreement, to grant to
Participants Shares without restrictions thereon as are deemed by the Committee
to be consistent with the purpose of the Plan.

            (f) Other Stock-Based Awards. The Committee is hereby authorized to
grant to Participants subject to the terms of the Plan and any applicable Award
Agreement, such other Awards that are denominated or payable in, valued in whole
or in part by reference to, or otherwise based on or related to, Shares
(including, without limitation, securities convertible into Shares), as are
deemed by the Committee to be consistent with the purpose of the Plan. Shares or
other securities delivered pursuant to a purchase right granted under this
Section 6(f) shall be purchased for such consideration, which may be paid by
such method or methods and in such form or forms (including, without limitation,
cash, Shares, promissory notes, other securities, other Awards or other property
or any combination thereof), as the Committee shall determine, the value of
which consideration, as established by the Committee, shall not be less than
100% of the Fair Market Value of such Shares or other securities as of the date
such purchase right is granted.

            (g) General.

                  (i) No Cash Consideration for Awards. Awards shall be granted
for no cash consideration or for such minimal cash consideration as may be
required by applicable law.

                  (ii) Awards May Be Granted Separately or Together. Awards may,
in the discretion of the Committee, be granted either alone or in addition to,
in tandem with or in substitution for any other Award or any award granted under
any plan of the Company or any Affiliate other than the Plan. Awards granted in
addition to or in tandem with other Awards or in addition to or in tandem with
awards granted under any such other plan of the Company or any Affiliate may be
granted either at the same time as or at a different time from the grant of such
other Awards or awards.

                  (iii) Forms of Payment under Awards. Subject to the terms of
the Plan and of any applicable Award Agreement, payments or transfers to be made
by the Company or an Affiliate upon the grant, exercise or payment of an Award
may be made in such form or forms as the Committee shall determine (including,
without limitation, cash, Shares, promissory notes, other securities, other
Awards or other property or any combination thereof), and may be made in a
single payment or transfer, in installments or on a deferred basis, in each case
in accordance with rules and procedures established by the Committee. Such rules
and procedures may include, without limitation, provisions for the payment or
crediting of reasonable interest on installment or deferred payments or the
grant or crediting of dividend equivalents with respect to installment or
deferred payments.

                  (iv) Limits on Transfer of Awards. No Award (other than Other
Stock Grants) and no right under any such Award shall be transferable by a
Participant otherwise than by will or by the laws of descent and distribution;
provided, however, that, if so determined by the Committee, a Participant may,
in the manner established by the Committee, transfer Options (other than
Incentive Stock Options) or designate a beneficiary or beneficiaries to exercise
the rights of the Participant and receive any property distributable with
respect to any Award upon the death of the Participant. Each Award or right
under any Award shall be exercisable during the Participant's lifetime only by
the Participant or, if permissible under applicable law, by the Participant's
guardian or legal representative. No Award or right under any such Award may be
pledged, alienated, attached or otherwise encumbered, and any purported pledge,
alienation, attachment or encumbrance thereof shall be void and unenforceable
against the Company or any Affiliate.

                  (v) Term of Awards. The term of each Award shall be for such
period as may be determined by the Committee.

                  (vi) Restrictions; Securities Exchange Listing. All Shares or
other securities delivered under the Plan pursuant to any Award or the exercise
thereof shall be subject to such restrictions as the Committee may deem
advisable under the Plan, applicable federal or state securities laws and
regulatory requirements, and the Committee may cause appropriate entries to be
made or legends to be affixed to reflect such restrictions. If any securities of
the Company are traded on a securities exchange, the Company shall not be
required to deliver any Shares or other securities covered by an Award unless
and until such Shares or other securities have been admitted for trading on such
securities exchange.

Section 7. Amendment and Termination; Adjustments.

            (a) Amendments to the Plan. The Board may amend, alter, suspend,
discontinue or terminate the Plan at any time; provided, however, that,
notwithstanding any other provision of the Plan or any Award Agreement, without
the approval of the shareholders of the Company, no such amendment, alteration,
suspension, discontinuation or termination shall be made that, absent such
approval would cause the Company to be unable, under the Code, to grant
Incentive Stock Options under the Plan.

                                      -8-
<PAGE>

            (b) Amendments to Awards. The Committee may waive any conditions of
or rights of the Company under any outstanding Award, prospectively or
retroactively. Except as otherwise provided herein or in the Award Agreement,
the Committee may not amend, alter, suspend, discontinue or terminate any
outstanding Award, prospectively or retroactively, if such action would
adversely affect the rights of the holder of such Award, without the consent of
the Participant or holder or beneficiary thereof.

            (c) Correction of Defects, Omissions and Inconsistencies. The
Committee may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem desirable to carry the Plan into effect.

Section 8. Income Tax Withholding; Tax Bonuses.

            (a) Withholding. In order to comply with all applicable federal or
state income tax laws or regulations, the Company may take such action as it
deems appropriate to ensure that all applicable federal or state payroll,
withholding, income or other taxes, which are the sole and absolute
responsibility of a Participant, are withheld or collected from such
Participant. In order to assist a Participant in paying all or a portion of the
federal and state taxes to be withheld or collected upon exercise or receipt of
(or the lapse of restrictions relating to) an Award, the Committee, in its
discretion and subject to such additional terms and conditions as it may adopt,
may permit the Participant to satisfy such tax obligation by (i) electing to
have the Company withhold a portion of the Shares otherwise to be delivered upon
exercise or receipt of (or the lapse of restrictions relating to) such Award
with a Fair Market Value equal to the amount of such taxes or (ii) delivering to
the Company Shares other than Shares issuable upon exercise or receipt of (or
the lapse of restrictions relating to) such Award with a Fair Market Value equal
to the amount of such taxes. The election, if any, must be made on or before the
date that the amount of tax to be withheld is determined.

            (b) Tax Bonuses. The Committee, in its discretion, shall have the
authority, at the time of grant of any Award under this Plan or at any time
thereafter, to approve cash bonuses to designated Participants to be paid upon
their exercise or receipt of (or the lapse of restrictions relating to) Awards
in order to provide funds to pay all or a portion of federal and state taxes due
as a result of such exercise or receipt (or the lapse of such restrictions). The
Committee shall have full authority in its discretion to determine the amount of
any such tax bonus.

Section 9. General Provisions.

            (a) No Rights to Awards. No Eligible Person, Participant or other
Person shall have any claim to be granted any Award under the Plan, and there is
no obligation for uniformity of treatment of Eligible Persons, Participants or
holders or beneficiaries of Awards under the Plan. The terms and conditions of
Awards need not be the same with respect to any Participant or with respect to
different Participants.

            (b) Award Agreements. No Participant will have rights under an Award
granted to such Participant unless and until an Award Agreement shall have been
duly executed on behalf of the Company and, if requested by the Company, signed
by the Participant.

                                      -9-
<PAGE>

            (c) No Limit on Other Compensation Arrangements. Nothing contained
in the Plan shall prevent the Company or any Affiliate from adopting or
continuing in effect other or additional compensation arrangements, and such
arrangements may be either generally applicable or applicable only in specific
cases.

            (d) No Right to Employment. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate, nor will it affect in any way the right of the Company
or an Affiliate to terminate such employment at any time, with or without cause.
In addition, the Company or an Affiliate may at any time dismiss a Participant
from employment free from any liability or any claim under the Plan or any
Award, unless otherwise expressly provided in the Plan or in any Award
Agreement.

            (e) Governing Law. The validity, construction and effect of the Plan
or any Award, and any rules and regulations relating to the Plan or any Award,
shall be determined in accordance with the laws of the State of Delaware,
without regard to choice of law principles.

            (f) Severability. If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction
or would disqualify the Plan or any Award under any law deemed applicable by the
Committee, such provision shall be construed or deemed amended to conform to
applicable laws, or if it cannot be so construed or deemed amended without, in
the determination of the Committee, materially altering the purpose or intent of
the Plan or the Award, such provision shall be stricken as to such jurisdiction
or Award, and the remainder of the Plan or any such Award shall remain in full
force and effect.

            (g) No Trust or Fund Created. Neither the Plan nor any Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant or
any other Person. To the extent that any Person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.

            (h) No Fractional Shares. No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash shall be paid in lieu of any fractional Shares or whether such
fractional Shares or any rights thereto shall be canceled, terminated or
otherwise eliminated.

            (i) Headings. Headings are given to the Sections and subsections of
the Plan solely as a convenience to facilitate reference. Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

Section 10. Effective Date of the Plan.

      The Plan shall be effective as of the date of its original approval by the
Board, subject to approval by the shareholders of the Company within one year
thereafter.

THIS STOCK OPTION AGREEMENT (this "Agreement"), dated as of the Option Grant
Date specified above, by and between BioForce Nanosciences Holdings, Inc., a
Delaware corporation (the "Company") and the Option Holder named above, is
entered into pursuant to The BioForce Nanosciences Holdings, Inc. 2006 Equity
Incentive Plan (as the same may be amended, restated, supplemented and other
modified from time to time, the "Plan"). All capitalized terms not otherwise
defined in the text of this Agreement have the meanings ascribed to them in the
Plan.

<PAGE>

1)    Grant of Options. Subject to the terms and conditions of the Plan and this
      Agreement, the Company hereby grants to the Option Holder the option (this
      "Option") to purchase from the Company the number of shares of Common
      Stock set forth above (such shares of Common Stock are referred to as the
      "Option Shares").

2)    Option Exercise Price. The exercise price to be paid for the Option Shares
      shall be as set forth above, which, with respect to Incentive Stock
      Options, is not less than [100%][110%](1) of the fair market value of the
      Option Shares on the Option Grant Date.

3)    Vesting. The Option Holder may only exercise the right to purchase the
      Option Shares to the extent such right is vested. The vesting schedule for
      the Option Holder's purchase right is set forth above. The right to
      purchase Option Shares shall only continue to vest while the Option Holder
      is employed by the Company or otherwise engaged as an Officer, Director or
      Consultant. If the Option Holder's services with the Company (or a
      Subsidiary) terminate for any reason, the Option Holder's purchase rights
      under this Agreement shall no longer continue to vest.

4)    Minimum Exercise Amount. The minimum number of Option Shares that the
      Option Holder may purchase at any time is [500] or such other number of
      shares as the Plan Administrator determines from time to time, provided
      that if the vested portion of this Option is less than such number of
      Option Shares, this Option may be exercised with respect to all Option
      Shares for which it is vested.

5)    Expiration of Option. Subject to the other provisions in this Agreement
      and the Plan that further limit or terminate the purchase rights of the
      Option Holder, none of the Option Shares may be purchased after 10 years
      from the Option Grant Date.

6)    Exercise of Options.

      a)    Except as otherwise provided herein, this Option may only be
            exercised by the Option Holder's delivery of an Exercise Notice
            during the Option Period to the Company (attention: 2006 Equity
            Incentive Plan Administrator), with cash payment in the amount of
            the exercise price multiplied by the number of Option Shares being
            purchased.

      b)    Upon fifteen (15) days advanced written notice by the Company to the
            Option Holder of the Company's intent to consummate a Change in
            Control, the Company shall have the right, exercisable in the
            Company's sole discretion, to require that the Option Holder
            exercise the Option Holder's right to purchase all the Options
            Shares that the Option Holder has a vested right to purchase within
            such fifteen-day period. If the Option Holder fails to exercise such
            right as to all the Option Shares that the Option Holder has a
            vested right to purchase within such fifteen-day period, then the
            Option Period with respect to the remaining Option Shares not so
            purchased shall immediately terminate.

      c)    If within thirty (30) days prior or one hundred eighty (180) days
            after a Change in Control, the services of Option Holder are
            terminated by the Company (for reasons other than for Cause) or are
            terminated by the Option Holder for Good Reason (as defined below),
            then the Option Holder shall have a vested right to purchase all of
            the Option Shares hereunder. As used herein, "Good Reason" means any
            of the following:

----------
(1)   Use 110% for stockholders owning greater than 10% of the issued and
      outstanding shares of stock.

                                      -2-
<PAGE>

            i)    A material reduction or negative change of the Option Holder's
                  duties and responsibilities (unless such reduction or change
                  is contemplated pursuant to a written agreement between the
                  Option Holder and the Company);

            ii)   A material change in the working conditions of the Option
                  Holder, including, without limitation, a significant
                  relocation (more than 200 miles) of the Option Holder's
                  principal workplace, without the consent of the Option Holder;
                  or

            iii)  A material change in the Company's principal business.

      d)    An Option Holder may pay for all or any portion of the aggregate
            exercise price for any Option Shares in accordance with the
            procedures set forth in Sections 8.1(b)(1) or 9.1(a) (as applicable)
            of the Plan, which Sections may be amended from time to time without
            the consent of the Option Holder. Upon receipt of the payment of the
            entire purchase price of the Option Shares so purchased and
            compliance with all the terms of the Plan and this Agreement,
            certificates for such Option Shares shall be issued to the Option
            Holder.

7)    Termination of Option Holder's Services.

      a)    If the Option Holder ceases to be an Employee, Officer, Director or
            Consultant of the Company for any reason other than death,
            Disability, or for Cause, this Option may be exercised, in whole or
            in part, but (i) only to the extent vested and exercisable on the
            date of such termination by the Option Holder, and (ii) only to the
            extent such Option is exercised within thirty (30) days after the
            date of such termination, or within such additional time period
            after termination as is approved by the Plan Administrator. If the
            holder of an ISO exercises such option more than ninety (90) days
            after termination of employment (other than by death or Disability),
            such option shall cease to be an ISO and shall be treated as an
            NQSO.

      b)    If the Option Holder ceases to be an Employee, Officer, Director or
            Consultant of the Company by reason of the Option Holder's death or
            Disability, this Option may be exercised, in whole or in part, but
            only to the extent vested and exercisable on the date of such death
            or Disability, within thirty (30) days after the date of death or
            Disability and not thereafter, by the person or persons entitled to
            do so under the Option Holder's will or, if the Option Holder fails
            to make a testamentary disposition of this Option or dies intestate
            or becomes subject to a Disability, by the Option Holder's legal
            representative or representatives, except as limited by law and the
            Code. If the holder of an ISO exercises such option more than ninety
            (90) days after termination of employment (other than by death or
            Disability), such option shall cease to be an ISO and shall be
            treated as an NQSO.

      c)    If the Option Holder ceases to be an Employee, Officer, Director or
            Consultant of the Company and the termination is for Cause, all of
            the Option Holder's rights hereunder shall immediately terminate
            (regardless of whether the purchase right is vested).

8)    Option Holder's Rights as a Stockholder. The Option Holder shall not be
      deemed for any purposes to be a stockholder of the Company solely by
      reason of holding this Option and shall not have any stockholder
      privileges with respect to any Option Shares, except to the extent that
      this Option has been exercised with respect thereto and a stock
      certificate issued therefore.

9)    Withholding. The Company may require as a condition precedent to the
      issuance or transfer of any Option Shares that the Option Holder make such
      arrangements as the Plan Administrator may require for the satisfaction of
      any federal, state or local withholding tax obligations that may arise. If
      the amount so requested is not paid, the Company may refuse to issue or
      permit the transfer of the Option Shares.

                                      -3-
<PAGE>

10)   Nontransferability of Options. This Option and any of the Option Holder's
      rights hereunder shall not be transferable by the Option Holder (other
      than by will or the laws of descent and distribution in the event of the
      Option Holder's death as provided in Section 7(b) hereof).

11)   Compliance with Securities Law. As required by the Plan, the right to
      purchase Option Shares under this Option may not be exercised unless, at
      the time of exercise, the Option Shares to be issued qualify for exemption
      from, or are registered pursuant to, applicable federal and state security
      laws. In the event there is not then on file with the Securities and
      Exchange Commission under the Securities Act of 1933, as amended, an
      effective registration statement, including a prospectus related to the
      Option Shares subject to this Option, the Option Holder shall execute and
      deliver to the Company prior to receipt by him or her of any of the Option
      Shares under this Agreement, the Investment Representation Statement,
      which form may be updated from time to time by the Company.

12)   Company Adjustments. The existence of the purchase rights under this
      Option shall not affect in any way the right or power of the Company or
      its stockholders to make or authorize any or all adjustments,
      recapitalizations, reorganizations, or other changes in the Company's
      capital structure or its business, or any merger or consolidation of the
      Company, or any issuance of bonds, debentures, preferred, or prior
      preference stock ahead of or affecting the Common Stock or the rights
      thereof, or dissolution or liquidation of the Company, or any sale or
      transfer of all or any part of its assets or business, or any other
      corporate act or proceeding, whether of a similar character or otherwise.

13)   Legend. In addition to any other restrictive legend required by agreement
      or by the Company, any certificate evidencing the Option Shares may bear
      the following legend:

            "The securities evidenced by this certificate have not been
            registered under the Securities Act of 1933, as amended (the
            "Securities Act"), or the securities laws of any state, but have
            been issued in reliance upon exemptions therefrom. The securities
            may not be offered, sold, pledged or otherwise transferred without
            registration under the Securities Act and applicable state
            securities laws or receipt of an opinion of counsel satisfactory to
            the Company that an exemption from registration is available or that
            such transfer may otherwise lawfully be made."

14)   Professional Advice. The acceptance and exercise of this Option and the
      sale of the Options Shares may have consequences under federal and state
      tax and securities laws, which may vary depending on the individual
      circumstances of the Option Holder. Accordingly, the Option Holder
      acknowledges that he has been advised to consult the Option Holder's
      personal, legal and tax advisor in connection with this Agreement and the
      acquisition, holding and disposition of the Option Shares. The Option
      Holder acknowledges that neither the Company nor any of its officers,
      directors, attorneys, or agents, have made any representations as to the
      federal and state tax effects of the acceptance of this Option, the
      exercise of this Option, or the vesting of the purchase rights under this
      Option.

15)   Interpretation. As a condition of the granting of this Option, the Option
      Holder agrees for himself or herself and his or her legal representatives,
      that any dispute or disagreement that may arise under or as a result of or
      pursuant to this Agreement shall be determined by the Plan Administrator
      in its sole discretion, and any interpretation by the Plan Administrator
      of the terms of this Agreement shall be final, binding, and conclusive.
