THIS STOCK OPTION AGREEMENT (the "Agreement"), dated as of the Option Grant Date
specified above, by and between BioForce Nanosciences Holdings, Inc., a Nevada
corporation (the "Company") and the Option Holder named above, is entered into
pursuant to the BioForce Nanosciences Holdings, Inc. Amended and Restated 2006
Equity Incentive Plan as the same may be amended, restated, supplemented and
otherwise 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.

3)    Vesting. The Option Holder may only exercise the right to purchase the
      Option Shares to the extent such right is vested and, except in the event
      of death, Disability or a Change in Control, six (6) months have lapsed
      since the Option Grant Date. The vesting schedule for the Option Holder's
      purchase right is set forth above except, in the case of a Change in
      Control all Options shall vest immediately and become exercisable. The
      right to purchase Option Shares shall only continue to vest while the
      Option Holder is employed by the Company or otherwise engaged as a
      non-employee officer or director, or a consultant or independent
      contractor. 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. Notwithstanding the
      foregoing, the Committee has the discretion to accelerate the vesting
      schedule by written consent.

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 Committee 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 ten (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: Human
            Resources), with payment in the amount of the exercise price
            multiplied by the number of Option Shares being purchased.

      b)    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 Section 8.2(a) or 9.2(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,
            consultant or independent contractor of the Company for any reason
            other than death, Disability, Change in Control, or Termination 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


                                      -2-
<PAGE>

            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 committee by written consent. If the holder of
            an ISO exercises such option more than ninety (90) days after
            termination of employment (other than employment termination due to
            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,
            consultant or independent contractor 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 ninety (90) 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.

      c)    If within thirty (30) days prior to or one hundred eighty (180) days
            after a Change in Control, the services of the Option Holder are
            terminated by the Company (for reasons other than Termination 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 within 60 days after
            termination of employment. As used herein, "Good Reason" means any
            of the following:

            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 100 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)    If the Option Holder ceases to be an Employee, officer, director,
            consultant or independent consultant of the Company due to
            Termination 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.

10)   Limited transferability of Options. This Option and any of the Option
      Holder's rights hereunder shall be transferable by the Option Holder as
      set forth in the Plan.


                                      -3-
<PAGE>

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
      securities 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 as may be 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 or she has been advised to consult the Option
      Holder's personal legal and/or tax advisor(s) 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, the vesting of the purchase rights under this
      Option, or the sale of any Option Shares.

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.

16)   Notices. All notices and other communications necessary or contemplated
      under this Agreement shall be in writing and shall be delivered in the
      manner specified herein or, in the absence of such specification, shall be
      deemed to have been duly given three (3) business days after mailing by
      certified mail, when delivered by hand, upon confirmation of receipt by
      telecopy, or one (1) day after sending by overnight delivery service, to
