number of whole Shares surrendered is less than the total exercise price of the
Option, the shortfall must be made up in cash or by check. Notwithstanding the
foregoing provisions of this Section 7(b), the consideration for Shares to be
issued pursuant to a Sale may not include, in whole or in part, the
consideration set forth in subsection (v) above.

      8. Exercise of Option.

            (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

            An Option may not be exercised for a fraction of a Share.

            An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under the Option Agreement and
Section 7(b) of the Plan. Each Optionee who exercises an Option shall, upon
notification of the amount due (if any) and prior to or concurrent with delivery
of the certificate representing the Shares, pay to the Company amounts necessary
to satisfy applicable federal, state and local tax withholding requirements. An
Optionee must also provide a duly executed copy of any stock transfer agreement
then in effect and determined to be applicable by the Administrator. Until the
issuance (as evidenced by the appropriate entry on the books of the Company or
of a duly authorized transfer agent of the Company) of the stock certificate
evidencing such Shares, no right to vote or receive dividends or any other
rights as a shareholder shall exist with respect to the Optioned Stock
represented by such stock certificate, notwithstanding the exercise of the
Option. No adjustment will be made for a dividend or other right for which the
record date is prior to the date the stock certificate is issued, except as
provided in Section 10 of the Plan.

            (b) Termination of Employment or Consulting Relationship. In the
event that an Optionee's Continuous Status as an Employee or Consultant
terminates (other than upon the Optionee's death or Disability), the Optionee
may exercise his or her Option, but only within such period of time as is
determined by the Administrator, and only to the extent that the Optionee was
entitled to exercise it at the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Notice of Grant).
The Administrator shall determine such period of time (in no event to exceed
ninety (90) days from the date of termination) when the Option is granted. If,
at the date of termination, the Optionee is not entitled to exercise his or her
entire Option, the Shares covered by the unexercisable portion of

7 - 2002 STOCK INCENTIVE PLAN (MICROHELIX, INC.)
<PAGE>
the Option shall revert to the Plan. If, after termination, the Optionee does
not exercise his or her Option within the time specified by the Administrator,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

            (c) Disability of Optionee. Unless otherwise determined by the
Administrator in the Option Agreement, in the event that an Optionee's
Continuous Status as an Employee or Consultant terminates as a result of the
Optionee's Disability, the Optionee may exercise his or her Option at any time
within twelve (12) months from the date of such termination, but only to the
extent that the Optionee was entitled to exercise it at the date of such
termination (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant). If, at the date of termination, the
Optionee is not entitled to exercise his or her entire Option, the Shares
covered by the unexercisable portion of the Option shall revert to the Plan. If,
after termination, the Optionee does not exercise his or her Option within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

            (d) Death of Optionee. Unless otherwise determined by the
Administrator in the Option Agreement, in the event of the death of an Optionee,
the Option may be exercised at any time within twelve (12) months following the
date of death (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant), by the Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent that the Optionee was entitled to exercise the Option at
the date of death. If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall revert to the Plan. If, after death, the Optionee's
estate or a person who acquired the right to exercise the Option by bequest or
inheritance does not exercise the Option within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

            (e) Buyout Provisions. The Administrator may at any time offer to
buy out, in whole or in part, for a payment in cash or Shares, an Option
previously granted, based on such terms and conditions as the Administrator
shall establish and communicate to the Optionee at the time that such offer is
made.

      9. Nontransferability of Options. Except as otherwise specifically
provided in the Option Agreement, an Option may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will, or by
the laws of descent and distribution, and may be exercised during the lifetime
of the Optionee only by the Optionee or, if incapacitated, by his or her legal
guardian or legal representative.

      10. Adjustments Upon Changes in Capitalization or Merger.

            (a) Changes in Capitalization: Subject to any required action by the
shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option and the number of shares of Common Stock which have been
authorized for issuance under the Plan but as to which no Options have yet been
granted or Sales made or which have been returned to the Plan upon cancellation
or expiration of an Option, as well as the price per share of Common Stock
covered by each such outstanding Option, shall be proportionately adjusted for
any increase or decrease in the number of issued shares of Common

8 - 2002 STOCK INCENTIVE PLAN (MICROHELIX, INC.)
<PAGE>
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the
Administrator, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, each outstanding Option will
terminate immediately prior to the consummation of such proposed action, unless
otherwise provided by the Administrator. The Administrator may, in the exercise
of its sole discretion in such instances, declare that any Option shall
terminate as of a date fixed by the Board and give each Optionee the right to
exercise Optionee's Option as to all or any part of the Common Stock subject to
the Option, including Shares as to which the Option would not otherwise be
exercisable.

            (c) Merger or Asset Sale. Except as otherwise provided in an Option
Agreement, in the event of a proposed sale of all or substantially all of the
assets of the Company, or the merger of the Company with or into another
corporation, each outstanding Option shall be assumed or an equivalent option
shall be substituted by such successor corporation or a Parent or Subsidiary of
such successor corporation, unless the Administrator determines, in the exercise
of its sole discretion and in lieu of such assumption or substitution, that each
Optionee shall have the right to exercise Optionee's Option as to all or any
part of the Common Stock subject to the Option, including Shares as to which the
Option would not otherwise be exercisable. If the Administrator determines that
an Option shall be exercisable in lieu of assumption or substitution in the
event of a merger or sale of assets, the Administrator shall notify the Optionee
that the Option shall be so exercisable for a period of thirty (30) days from
the date of such notice or such shorter period as the Administrator may specify
in the notice, and the Option will terminate upon the expiration of such period.
For the purposes of this paragraph, the Option shall be considered assumed if,
following the merger or sale of assets, the Option confers the right to
purchase, for each Share of Common Stock subject to the Option immediately prior
to the merger or sale of assets, the consideration (whether stock, cash, or
other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation and the
Optionee, provide for the consideration to be received upon the exercise of the
Option, for each Share of Common Stock subject to the Option, to be solely
common stock of the successor corporation or its Parent equal in Fair Market
Value to the per share consideration received by holders of Common Stock in the
merger or sale of assets.

9 - 2002 STOCK INCENTIVE PLAN (MICROHELIX, INC.)
<PAGE>
      11. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option. Notice of the determination shall be given to each
Optionee within a reasonable time after the date of such grant.

      12. Amendment and Termination of the Plan.

            (a) Amendment and Termination. The Board may amend or terminate the
Plan from time to time in such respects as the Board may deem advisable.

            (b) Shareholder Approval. The Company shall obtain shareholder
approval of any Plan amendment to the extent necessary and desirable to comply
with applicable law, rule or regulation, including the requirements of any
exchange or quotation system on which the Common Stock is listed or quoted. Such
shareholder approval, if required, shall be obtained in such a manner and to
such a degree as is required by the applicable law, rule or regulation.

            (c) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Administrator, which agreement must be in writing and signed by the Optionee
and the Company.

      13. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option or a Sale unless the exercise of such
Option or consummation of the Sale and the issuance and delivery of such Shares
pursuant thereto shall comply with all relevant provisions of law, including,
without limitation, the Securities Act of 1933, as amended, applicable state
securities laws, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange (including NASDAQ) upon
which the Shares may then be listed, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.

      14. Reservation of Shares. The Company, during the term of this Plan, will
at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

      15. Liability of Company.

            (a) Inability to Obtain Authority. Inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

            As a condition to the exercise of an Option or a Sale, the Company
may require the person exercising such Option or to whom Shares are being Sold
to represent and warrant at the time of any such exercise or Sale that the
Shares are being purchased only for investment and without any present intention
to sell or distribute such Shares if, in the opinion of counsel for the

10 - 2002 STOCK INCENTIVE PLAN (MICROHELIX, INC.)
<PAGE>
Company, such a representation is required by any of the aforementioned relevant
provisions of law.

            (b) Grants Exceeding Allotted Shares. If the Common Stock covered by
an Option exceeds, as of the date of grant, the number of Shares which may be
issued under the Plan without additional shareholder approval, such Option shall
be void with respect to such excess Common Stock, unless shareholder approval of
an amendment sufficiently increasing the number of Shares subject to the Plan is
timely obtained in accordance with Section 12 of the Plan.

      16. Market Standoff. In connection with any underwritten public offering
by the Company of its equity securities pursuant to an effective registration
statement filed under the Securities Act, an Optionee or other participant in
the Plan shall not sell, make any short sale of, loan, hypothecate, pledge,
grant any option for the purchase of, or otherwise dispose or transfer for value
or otherwise agree to engage in any of the foregoing transactions with respect
to, any shares issuable or issued under the Plan, whether pursuant to an Option
or a Sale, without the prior written consent of the Company or its underwriters.
Such limitations shall be in effect for such period of time as may be requested
by the Company or such underwriters and agreed to by the Company's officers and
directors with respect to their shares; provided, however, that in no event
shall such period exceed 180 days. The limitations of this paragraph shall in
all events terminate five years after the effective date of the Company's
initial public offering. Participants shall be subject to the market standoff
provisions of this Section 16 only if the officers and directors of the Company
are also subject to similar arrangements.

      In the event of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
Company's outstanding Common Stock effected as a class without the Company's
receipt of consideration, then any new, substituted or additional securities
distributed with respect to the purchased shares shall be immediately subject to
the provisions of this Section 16, to the same extent the purchased shares are
at such time covered by such provisions.

      In order to enforce the limitations of this Section 16, the Company may
impose stop-transfer instructions with respect to the purchased shares until the
end of the applicable standoff period.
