                             2003 STOCK OPTION PLAN

This 2003 Stock Option Plan (this "Plan") of BioForce Nanosciences, Inc. (the
"Company") is hereby established and provides for options (the "Option" or
"Options") for the purchase of shares of the Company's common stock, with a par
value of $0.01 per share ("Common Stock"). The Company intends that the Options
will be either Incentive Stock Options ("ISOs"), which qualify under Section 422
of the Internal Revenue Code of 1986, as amended (the "Code"), or options not
qualifying under Section 422 of the Code ("NQSOs").

1)    Purpose of this Plan. The Company believes it is desirable and in its best
      interest to adopt a stock option plan to aid in attracting, developing and
      retaining employees ("Employees") and others who are not employees,
      including nonemployee officers ("Officers"), directors ("Directors"), and
      consultants ("Consultants") of the Company and any subsidiary of the
      Company now or hereafter created by the Company (the "Subsidiary" or
      "Subsidiaries") capable of contributing to the future growth and
      operations of the Company or any Subsidiary (each Employee, Director,
      Officer and Consultant who receives an Option pursuant to this Plan is
      referred to as an "Option Holder").

2)    Administration of this Plan.

      a)    Plan Administrator. The Board of Directors of the Company (the
            "Board") shall administer this Plan, except that the Board may, in
            its discretion, appoint a Committee (the "Committee") consisting of
            members of the Board that shall administer this Plan. Any such
            Committee shall have such powers and authority as the Board may
            delegate to it. The Board or the Committee that administers this
            Plan shall be referred to as the "Plan Administrator."

      b)    Effective Date and Term. Subject to approval of the stockholders of
            the Company, the effective date of this Plan shall be as of January
            1, 2003. This Plan shall remain in effect subject to the terms
            hereof, until the earlier of the following: (1) December 31, 2012;
            (2) termination of this Plan by the Board; or (3) the purchase of
            all shares to be delivered pursuant to this Plan.

      c)    Plan Interpretation. The Plan Administrator shall construe and
            interpret this Plan, establish such rules as it deems necessary for
            the proper administration of this Plan and make such determinations
            and take such other action in connection with this Plan as it deems
            necessary and advisable. Subject to the terms of this Plan, the Plan
            Administrator shall decide the individuals to whom and the time or
            times at which Options shall be granted, the number of shares to be
            subject to each Option, the duration of the Options, the Option
            exercise price, and whether an Option is an ISO or NQSO. Any Options
            to be granted under this Plan must be granted within ten years from
            the effective date of this Plan.

      d)    No Liability. The Plan Administrator (or any member thereof) shall
            not be liable for any action or determination made in good faith
            with respect to this Plan or any Option granted under it.

3)    Maximum Number of Options Subject to this Plan. The shares to be offered
      under this Plan may be, in whole or in part, authorized but unissued
      shares of Common Stock or issued shares of Common Stock that have been
      reacquired by the Company. The aggregate number of shares of Common Stock
      to be delivered upon exercise of all Options granted under this Plan shall
      not exceed One Million (1,000,000) shares of Common Stock as of the date
      of this Plan (as adjusted for any stock split, stock dividend, or share
      reclassification). If any Option granted hereunder shall expire,
      terminate, or be forfeited for any reason without having been exercised in
      full, the shares of Common Stock subject to such Option not purchased may
      again be granted under this Plan unless this Plan shall have been
      terminated.

4)    Selection of Option Recipients. The Plan Administrator, from time to time,
      subject to the terms and provisions of this Plan, may grant Options to
      such present and future key Employees, Officers, Directors and Consultants
      of the Company, and of its Subsidiaries, as it shall determine. In
      determining the persons to whom Options shall be granted and the number of
      shares available under each Option, the Plan Administrator may take into
      account the nature of the services rendered by such persons, their present
      and potential contributions to the success and growth of the Company and
      such other factors as the Plan Administrator, in its discretion, shall
      deem relevant.

5)    Option Requirements. The Options granted pursuant to this Plan shall be
      authorized by the Plan Administrator and shall be evidenced by an Option
      Agreement that shall include the following terms and conditions:

      a)    Option Holder and Option Grant Date. Each Option Agreement shall
            state the name of the Option Holder and the date on which the Option
            was granted.

      b)    Exercise Price. Each Option Agreement shall state the Option
            exercise price, as determined by the Plan Administrator. The per
            share exercise price for an ISO shall not be less than the fair
            market value per share of Common Stock at the date of grant as
            determined by the Plan Administrator in good faith; provided,
            further, that with respect to ISOs granted to stockholders owning
            greater than 10% of the issued and outstanding shares of Common
            Stock, the exercise price per share shall not be less than 110% of
            the fair market value per share of Common Stock at the date of
            grant.

      c)    Number of Shares. Each Option Agreement shall state the number of
            shares of Common Stock available for purchase under such Option
            Agreement.

      d)    Type of Option. Each Option Agreement shall state whether the Option
            is an ISO or an NQSO, or combination thereof. ISOs shall be granted
            only to Employees. The aggregate fair market value (determined at
            the date of grant) of the stock with respect to which ISOs are
            exercisable by the Option Holder during any calendar year (granted
            under this Plan and all other ISO plans of the Company, a related
            corporation or a predecessor corporation) shall not exceed $100,000
            or such other limit as may be prescribed by the Code, as amended
            from time to time. Any Option that is identified as an ISO but
            exceeds the above annual limit or otherwise fails to qualify for
            treatment as an ISO shall not be void but rather shall be a NQSO to
            the extent it exceeds such annual limit or otherwise fails to
            qualify for such treatment.

      e)    Payment. Each Option Agreement shall state that the Option exercise
            price shall be payable upon the exercise of the Option and shall be
            paid in cash or by check in United States Dollars. In addition, if
            provided in the Option Agreement and upon approval of the Plan
            Administrator, an Option Holder may pay for all or any portion of
            the aggregate Option exercise price for any shares of Common Stock
            purchased upon the exercise of any Option by delivering to the
            Company shares of Common Stock previously held by such Option Holder
            or, with the prior consent of the Plan Administrator, by having
            shares withheld from the amount of shares of Common Stock to be
            received by the Option Holder upon exercise of the Option. The
            shares of Common Stock received or withheld by the Company as
            payment for shares of Common Stock purchased upon the exercise of an
            Option shall have a fair market value at the date of exercise (as
            determined by the Plan Administrator) equal to the aggregate Option
            exercise price (or portion thereof) to be paid through the exchange
            of previously held shares of Common Stock or through the withholding
            of shares of Common Stock to be received by the Option Holder upon
            exercise. In addition, upon approval by the Plan Administrator, the
            Company may lend an amount equal to the Option exercise price to an
            Option Holder on terms approved by the Plan Administrator.

                                       2

      f)    Duration of Options. Each Option to be granted may be exercised
            within such period as may be determined by the Plan Administrator.
            The expiration date of the Option, shall not be later than ten years
            from the date of grant; provided, however, that the expiration date
            of any ISO granted to a stockholder owning more than ten percent
            (10%) of the issued and outstanding shares shall not be a term that
            is greater than five years from the date of grant.

      g)    Vesting of Options. An Option Agreement may contain a vesting
            schedule (that may be different for each Option Holder) as
            determined by the Plan Administrator. The Plan Administrator may
            accelerate the vesting at such times and in such amounts as it shall
            determine in its sole discretion.

      h)    Exercise of Options. Each Option Holder shall have the right to
            exercise his or her Option in the manner specified in the Option
            Agreement evidencing the granting of such Option. The time period in
            which the Option Holder has a vested right (that has not terminated
            or been forfeited) to purchase shares of Common Stock under an
            Option Agreement is referred to as the "Option Period."

      i)    Method of Exercise. Each Option shall be exercised pursuant to the
            terms of this Plan by giving written notice to the Company at its
            principal place of business. The form of such notice shall be
            substantially similar to the Exercise Notice contained in Exhibit A
            and shall include the Investment Representation Statement contained
            in Exhibit B signed by the Option Holder. No portion of any Option
            may be exercised for less than five hundred (500) shares or such
            other number of shares as the Plan Administrator determines from
            time to time, provided that if the vested portion of any Option is
            less than such number of shares, the Option may be exercised with
            respect to all shares for which it is vested. The Company shall make
            delivery of such shares as set forth in the Option Agreement;
            provided, however, that if any law or regulation requires the
            Company to take action with respect to the shares specified in such
            notice before issuance thereof, the date of delivery of such shares
            shall then be extended for the period necessary to take such action.
            The Company shall not be obligated to issue, transfer, or deliver a
            certificate of Common Stock to any Option Holder, or to such Option
            Holder's personal representative, until the aggregate Option price
            has been paid for all shares for which the Option shall have been
            exercised.

      j)    Securities Law Requirements. No Option granted under this Plan may
            be exercised unless, at the time of exercise, Common Stock to be
            issued qualifies for exemption from, or is registered pursuant to,
            applicable federal and state securities laws. In the event there
            shall not then be on file with the Securities and Exchange
            Commission under the Securities Act of 1933, as amended, an
            effective registration statement, including a prospectus relating to
            the shares subject to the Option, the Plan Administrator may require
            the Option Holder to execute and deliver to the Company prior to
            receipt by such Option Holder of any such shares under this Plan, in
            addition to the Investment Representation Statement, an investment
            letter in form and substance satisfactory to the Company.

      k)    Withholding. As a condition to the exercise of any Option granted
            hereunder, the Option Holder shall make such arrangements as the
            Plan Administrator may require for the satisfaction of any federal,
            state or local withholding tax obligations that may arise in
            connection with such exercise. Such arrangements may include the
            deduction of any such required withholding from any payments due or
            to become due to the Option Holder.

                                       3

      l)    Reload Option. If an Option Agreement provides, the Plan
            Administrator permits, and an Option Holder pays for all or any
            portion of the aggregate Option exercise price with shares of Common
            Stock or withholding a number of shares upon exercise of an Option
            pursuant to Section 5(e), the Plan Administrator may grant reload
            Options. Such reload Options may grant the Option Holder a new
            Option Agreement for the number of shares of Common Stock equal to
            the number tendered as consideration for the purchase of shares
            under the former Option Agreement under terms satisfactory to the
            Plan Administrator.

      m)    Other Conditions, Restriction, Contingencies. Each Option Agreement
            shall specify the other conditions, restrictions and contingencies
            to which the Option is subject as deemed necessary or appropriate by
            the Plan Administrator.

6)    Stockholders Agreement. As a condition of the exercising of any Option
      granted pursuant to this Plan, in whole or in part, the Plan Administrator
      may require the Option Holder to execute the Stockholders Agreement, the
      form of which shall be substantially similar to the one attached hereto in
      Exhibit C.

7)    Limited Transferability of Options. During the Option Holder's lifetime,
      only the Option Holder may exercise Options. Options shall not be
      transferable other than by will or the laws of descent and distribution
      and shall terminate as provided under this Plan and as specified in the
      Option Agreement.

8)    Status as Stockholder. Neither the Option Holder nor the Option Holder's
      executor, administrator, heirs, legatees, or successors shall be or have
      any rights or privileges of a stockholder of the Company solely by reason
      of holding any Option, unless and until the Option has been exercised and
      certificates representing such shares shall have been issued and delivered
      to the Option Holder.

9)    Effective Date of Termination of Employment. Termination of employment
      shall be considered to have occurred on the earlier of the last day of
      performance of services or the first date written notice of termination is
      given by either the Company or its Subsidiary without regard to the actual
      last day of performance of services, whichever occurs first. A leave of
      absence approved in writing by the Board shall not be a termination of
      employment for purposes of this Plan.

10)   Termination of Employment Due to Death or Disability. Unless an Option
      Holder's employment agreement with the Company or the Option Agreement
      states otherwise, the following shall apply to each Option Holder who was
      granted an Option when such Option Holder was an Employee:

      a)    Termination by Death or Disability. In the event the employment of
            an Employee is terminated by reason of death or a permanent and
            total disability (as defined in Section 22(e)(3) of the Code and
            determined by the Company, "Disability"), all purchase rights under
            outstanding Options granted to that Employee that are not vested
            shall be immediately forfeited to the Company and all purchase
            rights under outstanding Options that are vested shall remain
            exercisable at any time prior to their expiration date or for one
            (1) year after the date of death or the determination by the Company
            of the existence of a Disability, whichever period is shorter, by
            such person or persons as shall have been named as the Employee's
            beneficiary or guardian, or by such persons that have acquired the
            Employee's rights under the Option by will or by the laws of descent
            and distribution.

                                       4
<PAGE>

      b)    Exercise Limitations on ISOs. In the case of ISOs, the tax treatment
            prescribed under Section 422 of the Code may not be available if the
            Options are not exercised within the Section 422 prescribed time
            periods after each of the various types of employment termination.

11)   Termination of Employment for Other Reasons. Except as otherwise provided
      in an Option Holder's employment agreement with the Company or in the
      Option Holder's Option Agreement, if the employment of an Employee
      terminates for any reason other than the reasons set forth in Section 10
      (and other than for Cause), all purchase rights under Options held by the
      Employee that are not vested as of the effective date of employment
      termination immediately shall be forfeited to the Company. However, the
      Plan Administrator, in its sole discretion, shall have the right to
      immediately vest all or any portion of such Options, subject to such terms
      as the Plan Administrator, in its sole discretion, deems appropriate. The
      Employee may exercise options that are vested as of the effective date of
      employment termination no later than sixty (60) days after the effective
      date of employment termination or on such later date as is approved by the
      Plan Administrator or as stated in the Option Agreement. Notwithstanding
      anything contained in this Plan, if the Company terminates the employment
      of an Employee for Cause, all purchase rights under outstanding Options
      held by the Option Holder shall be forfeited to the Company immediately
      and no additional exercise period shall be allowed, regardless of the
      vested status of the Options. As used herein, "Cause" means, unless
      defined otherwise in an agreement between the Option Holder and the
      Company referencing this Plan, any of the following as determined in good
      faith by the Plan Administrator:

      a)    The Option Holder has committed gross negligence, willful misconduct
            or any violation of law in the performance of the Option Holder's
            duties to the Company or any Subsidiary;

      b)    The Option Holder has willfully failed to follow reasonable
            instructions from the Company or any Subsidiary;

      c)    The Option Holder has been convicted or charged with a felony deemed
            by the Company to be adverse to its best interests or reputation;

      d)    The Option Holder has misappropriated funds or property of the
            Company or any Subsidiary;

      e)    The Option Holder has attempted to obtain an improper personal
            profit from any transaction in which the Company or any Subsidiary
            has an interest, and which represents a corporate opportunity of the
            Company or any Subsidiary or is adverse to the interests of the
            Company or any Subsidiary, unless the transaction was approved in
            writing by the Company after full disclosure of all details relating
            to the transaction; or

      f)    The Option Holder has breached a material provision of any agreement
            to which the Option Holder and Company or any Subsidiary are parties
            or has breached any material obligation or duty owed to the Company
            or any Subsidiary.

12)   Termination of Services as an Officer or Director. Except as provided in
      an Officer's or Director's Option Agreement, if an Officer's or Director's
      tenure ends because of death, Disability, or for other reasons, all
      purchase rights under outstanding Options granted to that Officer or
      Director that are not vested shall be immediately forfeited to the Company
      as of the Officer's or Director's last day of service as an Officer or
      Director of the Company. Following the date on which the Officer or
      Director ceases to serve in such capacity, other than as a result of
      removal for Cause, all purchase rights under outstanding Options that are
      vested shall remain exercisable, to the extent such Options may be
      exercised pursuant to this Plan, until the earlier of the following: (i)
      sixty (60) days from the date the Officer or Director ceases to serve in
      such capacity; or (ii) the expiration of the original Option term. If an
      Officer or Director is removed for Cause, all purchase rights under
      outstanding Options held by the Officer or Director shall be immediately
      forfeited to the Company and no additional exercise period shall be
      allowed, regardless of the vested status of the Options.

                                       5
<PAGE>

13)   Termination of Services as a Consultant. Except as provided in a
      Consultant's consulting agreement with the Company or the Consultant's
      Option Agreement, if a Consultant's engagement ends because of death,
      Disability, or any other reason, all purchase rights under outstanding
      Options granted to that Consultant that are not vested shall be
      immediately forfeited to the Company as of the Consultant's last day of
      service as a Consultant to the Company. Following the date on which the
      Consultant ceases to serve as a Consultant, other than termination for
      Cause, all purchase rights under outstanding Options that are vested shall
      remain exercisable, to the extent such options may be exercised pursuant
      to this Plan, until the earlier of the following: (i) sixty (60) days from
      the date the Consultant ceases to serve in such capacity; or (ii) the
      expiration of the original Option term. If a Consultant's services are
      terminated for Cause, all purchase rights under outstanding Options shall
      be immediately forfeited to the Company and no additional exercise period
      shall be allowed regardless of the vested status of the Options.

14)   Change in Control. Except as provided in an Option Holder's Option
      Agreement, upon fifteen (15) days advance 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 shares that the Option Holder has a
      vested right to purchase under existing Option Agreements within such
      fifteen-day period. If the Option Holder fails to exercise such right as
      to all the shares that the Option Holder has a vested right to purchase
      within such fifteen-day period, then to the extent not so exercised, all
      remaining purchase rights under the outstanding Options (regardless of
      their vested status) shall be immediately forfeited to the Company. Unless
      otherwise specifically prohibited by the terms of this Plan or by law, and
      subject to Section 16 herein, the Plan Administrator shall have the
      authority to make any modifications to the Option Agreements as determined
      by the Plan Administrator (including, but not limited to, accelerating the
      vesting on Options granted under this Plan) to be appropriate before the
      effective date of the Change in Control, including but not limited to,
      shortening the time during in which the ISOs or NQSOs may be exercised or
      accelerating the vesting schedule.

a)    "Change in Control" means, with respect to the Company, the occurrence of
      any one or more of the following:

            (1)   Any individual, partnership, corporation, limited liability
                  company, or other organizations, or any combination thereof
                  (other than those persons in control of the Company as of the
                  date hereof), becomes the beneficial owner, directly or
                  indirectly, of securities of the Company representing more
                  than seventy percent (70%) of the combined voting power of the
                  Company's then outstanding securities; or

            (2)   The stockholders of the Company approve:

                  (a)   A plan of complete liquidation of the Company;

                  (b)   An agreement for the sale or disposition of all or
                        substantially all the Company's assets; or

                  (c)   A merger, consolidation, or reorganization of the
                        Company with or involving any other entity, other than a
                        merger, consolidation, or reorganization that would
                        result in the voting securities of the Company
                        outstanding immediately prior thereto continuing to
                        represent (either by remaining outstanding or by being
                        converted into voting securities of the surviving
                        entity), more that fifty percent (50%) of the combined
                        voting power of the voting securities of the Company (or
                        such surviving entity) outstanding immediately after
                        such merger, consolidation, or reorganization.

                                       6

15)   Action by the Company. The existence of Options shall not impair the right
      of the Company or its stockholders to make or effect any 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 issue of bonds, debentures, preferred or prior preference
      stocks ahead of or affecting Common Stock or the rights thereof, or the
      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.

16)   Termination and Amendment. The Plan Administrator may at any time suspend
      or terminate this Plan. The Plan Administrator may also at any time amend
      or revise the terms and provisions of this Plan, subject to stockholder
      approval to the extent such approval is required to allow Options issued
      pursuant to this Plan to satisfy the requirements for ISO treatment under
      the Code. No termination, suspension or modification of this Plan may be
      made that materially and adversely affects any Option Holder without the
      consent of such Option Holder adversely affected thereby, except that the
      Company may require all of the Options issued under this Plan be
      surrendered in connection with a Change in Control if so provided under
      the Option Agreement.

17)   No Grant of Options. Nothing contained in this Plan or any resolution
      adopted or to be adopted by the Board shall constitute the granting of any
      Option hereunder. The granting of an Option pursuant to this Plan shall
      take place only when a written Option Agreement has been duly executed and
      delivery made by or on behalf of the Company to the person to whom such
      Option is granted.

18)   Adjustment of Options. In the event of any stock split, stock dividend, or
      recapitalization, merger, consolidation, spin-off, reorganization,
      combination or exchange of shares or other similar corporate change which
      would affect any outstanding Option, the number and kind of shares covered
      by such outstanding Option and the Option Price shall be adjusted by the
      Plan Administrator to prevent the dilution or enlargement of the Option
      Holders' rights.

19)   Governing Law. To the extent not preempted by federal law, this Plan, and
      all agreements hereunder, shall be construed in accordance with and
      governed by the laws of the State of Delaware.

Attn: 2003 Stock Option Plan Administrator

      1.    Exercise of Option. Effective as of today, ______________________
            ______, 200____, the undersigned ("Option Holder") hereby elects to
            exercise his or her option to purchase _____________________ shares
            of the Common Stock (the "Shares") of BioForce Nanosciences, Inc.
            (the "Company"), under and pursuant to the Company's 2003 Stock
            Option Plan (the "Plan") and the Stock Option Agreement dated
            ______________________ ______, 200____, (the "Option Agreement"), of

            the Shares and that Option Holder is not relying on the Company for
            any tax advice.

                       INVESTMENT REPRESENTATION STATEMENT

OPTION HOLDER:    ______________________________________________

COMPANY:          BioForce Nanosciences, Inc.

SECURITY:         Common Stock

AMOUNT:           ______________________________________________

DATE:             ______________________________________________

In connection with the purchase of the above-listed securities (the
"Securities"), the undersigned Option Holder represents to the Company the
following:

1)    Option Holder is aware of the Company's business affairs and financial
      condition and has acquired sufficient information about the Company to
      reach an informed and knowledgeable decision to acquire the Securities.
      Option Holder is acquiring the Securities for investment for Option
      Holder's own account only and not with a view to, or for resale in
      connection with, any "distribution" thereof within the meaning of the
      Securities Act of 1933, as amended (the "Securities Act").

2)    Option Holder acknowledges and understands that the Securities constitute
      "restricted securities" under the Securities Act and have not been
      registered under the Securities Act in reliance upon a specific exemption
      therefrom, which exemption depends upon, among other things, the bona fide
      nature of Option Holder's investment intent as expressed herein. In this
      connection, Option Holder understands that, in the view of the Securities
      and Exchange Commission, the statutory basis for such exemption may be
      unavailable if Option Holder's representation was predicated solely upon a
      present intention to hold these Securities for the minimum capital gains
      period specified under tax statues, for a deferred sale, for or until an
      increase or decrease in the market price of the Securities, or for a
      period of one year or any other fixed period in the future. Option Holder
      further understands that the Securities must be held indefinitely unless
      they are subsequently registered under the Securities Act or an exemption
      from such registration is available. Option Holder further acknowledges
      and understands that the Company is under no obligation to register the
      Securities. Option Holder understands that the certificate evidencing the
      Securities will be imprinted with a legend that prohibits the transfer of
      the Securities unless they are registered or such registration is not
      required in the opinion of counsel satisfactory to the Company, and any
      other legend required under applicable state securities laws.

3)    Option Holder is familiar with the provisions of Rule 701 and Rule 144,
      each promulgated under the Securities Act, which, in substance, permit
      limited public resale of "restricted securities" acquired, directly or
      indirectly from the issuer thereof, in a non-public offering subject to
      the satisfaction of certain conditions. Rule 701 provides that if the
      issuer qualifies under Rule 701 at the time of the grant of the Option to
      the Option Holder, the exercise will be exempt from registration under the
      Securities Act. In the event the Company becomes subject to the reporting
      requirements of Section 13 or 15(d) of the Securities Exchange Act of
      1934, as amended, ninety (90) days thereafter (or such longer period as
      any market stand-off agreement may require) the Securities exempt under
      Rule 701 may be resold, subject to the satisfaction of certain of the
      conditions specified by Rule 144, including the following: (1) the resale
      being made through a broker in an unsolicited "broker's transaction" or in
      transactions directly with a market maker (as said term is defined under
      the Securities and Exchange Act of 1934); and, in the case of an
      affiliate, (2) the availability of certain public information about the
      Company, (3) the amount of Securities being sold during any three month
      period not exceeding the limitations specified in Rule 144(e), and (4) the
      timely filing of a Form 144, if applicable.

                                       3
<PAGE>

      In the event that the Company does not qualify under Rule 701 at the time
      of grant of the Option, then the Securities may be resold in certain
      limited circumstances subject to the provisions of Rule 144, which
      requires the resale to occur not less than one year after the later of the
      date the Securities were sold by the Company or the date the Securities
      were sold by an affiliate of the Company, within the meaning of Rule 144;
      and, in the case of acquisition of the Securities by an affiliate, or by a
      non-affiliate who subsequently holds the Securities less than two years,
      the satisfaction of the conditions set forth in sections (1), (2), (3) and
      (4) of the paragraph immediately above.

4)    Option Holder further understands that in the event all of the applicable
      requirements of Rule 701 or 144 are not satisfied, registration under the
      Securities Act, compliance with Regulation A, or some other registration
      exemption will be required; and that, notwithstanding the fact that Rules
      144 and 701 are not exclusive, the Staff of the Securities and Exchange
      Commission has expressed its opinion that persons proposing to sell
      private placement securities other than in a registered offering and
      otherwise than pursuant to Rules 144 or 701 will have a substantial burden
      of proof in establishing that an exemption from registration is available
      for such offers or sales, and that such persons and their respective
      brokers who participate in such transactions do so at their own risk.
      Option Holder understands that no assurances can be given that any such
      other registration exemption will be available in such event.
