4.   ADMINISTRATION OF THE PLAN.

     (a) PROCEDURE. The Plan shall be administered by the Board of Directors.
The Board of Directors may appoint a Committee consisting of not less than two
members of the Board of Directors to administer the Plan on behalf of the Board
of Directors, subject to such terms and conditions as the Board of Directors may

not be identical) in accordance with the Plan, and, with the consent of the
holder thereof with respect to any adverse change, modify or amend each Option;
(viii) to accelerate or defer (the latter with the consent of the Optionee) the
exercise date and vesting of any Option; (ix) to authorize any person to execute
on behalf of the Company any instrument required to effectuate the grant of an
Option previously granted by the Board; and (x) to make all other determinations
deemed necessary or advisable for the administration of the Plan.

     (c) EFFECT OF BOARD'S DECISION. All decisions, determinations and
interpretations of the Board shall be final and binding on all Optionees and any
other holders of any Options granted under the Plan.

5.   ELIGIBILITY.

     Options may be granted only to Employees or Consultants as defined in
Section 2 hereof. An Employee or Consultant who has been granted an Option
may, if he or she is otherwise eligible, be granted an additional Option or
Options. Notwithstanding the foregoing, no Employee who is an Officer of the
Company or who is a member of the Board of Directors shall be entitled to
receive the grant of an Option under the Plan.

     The Plan shall not confer upon any Optionee any right with respect to
continuation of employment or consulting with the Company, nor shall it
interfere in any way with the Optionee's right or the Company's right to
terminate the Optionee's employment at any time or the Optionee's consulting
for the Company pursuant to the terms of the Consultant's agreement with the
Company.

6.   TERM OF THE PLAN.

     The Plan shall become effective upon its adoption by the Board of
Directors. It shall continue in effect until terminated under Section 13 of
the Plan.

7.   TERM OF OPTION.

     The term of each  Option  shall be ten (10) years from the date of grant
thereof or such  shorter  term as may be provided in the Option Agreement.

8.   EXERCISE PRICE, CONSIDERATION AND VESTING.

     (a) EXERCISE PRICE. The per Share exercise price for the Shares to be
issued pursuant to exercise of an Option shall be no less than 85% of the Fair
Market Value per Share on the date of grant. Notwithstanding the foregoing, an
Option may be granted with an exercise price lower than that set forth in the
preceding sentence if such Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section
424(a) of the Code.

     (b) CONSIDERATION. The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Board and may consist entirely of (i) cash or check; (ii) other shares of
the Common Stock of the Company having a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which the
Option shall be exercised, including by delivering to the Company an attestation
of ownership of owned and unencumbered shares of the Common Stock of the Company
in a form approved by the Company; (iii) payment pursuant to a program developed
under Regulation T as promulgated by the Federal Reserve Board which, prior to
the issuance of Common Stock, results in either the receipt of cash (or check)
by the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds; (iv) any combination of
such methods of payment; or (v) such other consideration and


                                      4
<PAGE>

method of payment for the issuance of Shares to the extent permitted under
applicable law. In making its determination as to the type of consideration
to accept, the Board shall consider if acceptance of such consideration may
be reasonably expected to benefit the Company.

     (c) VESTING. The total number of Shares subject to an Option may, but need
not, be allotted in periodic installments (which may, but need not, be equal).
The Option Agreement may provide that, from time to time during each of such
installment periods, the Option may become exercisable ("vest") with respect to
some or all of the Shares allotted to that period, and may be exercised with
respect to some or all of the Shares allotted to such period and/or any prior
period as to which the Option became vested but was not fully exercised. The
Option may be subject to such other terms and conditions on the time or times
when it may be exercised (which may be based on performance or other criteria)
as the Board may deem appropriate. The provisions of this Section 8(c) are
subject to any Option provisions governing the minimum number of Shares as to
which an Option may be exercised.

9.   EXERCISE OF OPTION.

     (a) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option granted
hereunder shall be exercisable at such times and under such conditions as
determined by the Board, 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 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 Board, consist of any
consideration and method of payment allowable under Section 8(c) of the Plan.
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 stockholder shall exist with respect to the Optioned
Stock, 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 11 of the
Plan. An Option may not be exercised for a fraction of a Share.

     Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

     The Option may, but need not, include a provision whereby the Optionee
may elect at any time while an Employee or Consultant (or while an officer or
director of the Company) to exercise the Option as to any part or all of the
shares subject to the Option, subject to a repurchase right in favor of the
Company on such terms as the Board shall establish.

     (b) TERMINATION OF SERVICE AS AN EMPLOYEE OR CONSULTANT. If an Optionee's
Continuous Service as an Employee or Consultant ceases for any reason other than
death or disability, the Optionee may, but only within three (3) months (or such
other period of time as is


                                      5
<PAGE>

determined by the Board) after the date the Optionee's Continuous Service as
an Employee or Consultant ceases, exercise the Option to the extent that the
Optionee was entitled to exercise it at the date of such termination. To the
extent that the Optionee was not entitled to exercise the Option at the date
of such termination, or if the Optionee does not exercise such Option (which
the Optionee was entitled to exercise) within the time specified herein, the
Option shall terminate.

     (c) DEATH OF OPTIONEE. In the event of the death during the term of the
Option of an Optionee who is at the time of his or her death an Employee or
Consultant and who shall have been in Continuous Service as an Employee or
Consultant since the date of grant of the Option, or in the event of the death
of an Optionee within three (3) months following the termination of the
Optionee's Continuous Service as an Employee or Consultant for any other reason,
the Option may be exercised at any time within eighteen (18) months (or such
other period of time as is determined by the Board) following the date of death
by the Optionee's estate or by a person who acquired the right to exercise the
Option by bequest or inheritance, to the extent that the Optionee was entitled
to exercise it at the date of such termination. To the extent that the Optionee
was not entitled to exercise the Option at the date of such termination, or if
the Option is not exercised (to the extent the Optionee was entitled to
exercise) within the time specified herein, the Option shall terminate.

     (d) DISABILITY OF OPTIONEE. In the event of the disability during the term
of the Option of an Optionee who is at the time of his or her disability an
Employee or Consultant and who shall have been in Continuous Service as an
Employee or Consultant since the date of grant of the Option, the Optionee may,
but only within twelve (12) months (or such other period of time as is
determined by the Board) after the date the Optionee ceases to be an Employee or
Consultant on account of such disability, exercise the Option to the extent that
the Optionee was entitled to exercise it at the date of such termination. To the
extent that the Optionee was not entitled to exercise the Option at the date of
such termination, or if the Optionee does not exercise such Option (which the
Optionee was entitled to exercise) within the time specified herein, the Option
shall terminate.

     (e) WITHHOLDING. To the extent provided by the terms of the Option
Agreement, the Optionee may satisfy any federal, state or local tax withholding
obligation relating to the exercise of such Option by any of the following means
( in addition to the Company's right to withhold from any compensation paid to
Optionee by the Company)or by a combination of such means: (i) tendering a cash
payment; (ii) authorizing the Company to withhold Shares from the Shares
otherwise issuable to the Optionee as a result of the exercise of the Option; or
(iii) delivering to the Company owned and unencumbered shares of the Common
Stock of the Company.

10.  TRANSFERABILITY OF OPTIONS.

     Except as otherwise expressly provided in the terms of the Option
Agreement, the 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 or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. Notwithstanding the foregoing, the Optionee
may, by delivering written notice to the Company, in a form satisfactory to
the Company,


                                      6
<PAGE>

designate a third party who, in the event of the death of the Optionee, shall
thereafter be entitled to exercise the Option.

11.  ADJUSTMENTS UPON CHANGES IN STOCK.

     (a) If any change is made in the stock subject to the Plan, or subject to
any Option, without the receipt of consideration by the Company (through merger,
consolidation, reorganization, recapitalization, reincorporation, stock
dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or other transaction not involving the receipt of consideration by the
Company), the Plan and the outstanding Options will be appropriately adjusted in
the class(es) and number of securities and price per share of stock subject to
such outstanding Options. Such adjustments shall be made by the Board, the
determination of which shall be final, binding and conclusive. (The conversion
of convertible securities, cashless exercise of options and net exercise of
warrants shall not be treated as transactions "without receipt of consideration"
by the Company.)

     (b) In the event of: (1) a dissolution or liquidation of the Company; (2) a
merger or consolidation in which the Company is not the surviving corporation;
or (3) a reverse merger in which the Company is the surviving corporation but
the shares of the Company's common stock outstanding immediately preceding the
merger are converted by virtue of the merger into other property, whether in the
form of securities, cash or otherwise, then, subject to paragraph (c) of this
Section 11, at the sole discretion of the Board and to the extent permitted by
applicable law: (i) any surviving corporation shall assume any Options
outstanding under the Plan or shall substitute similar Options for those
outstanding under the Plan, (ii) such Stock Awards shall continue in full force
and effect, or (iii) the time during which such Stock Awards become vested or
may be exercised shall be accelerated and any outstanding unexercised rights
under any Stock Awards terminated if not exercised prior to such event. In the
event any surviving corporation or acquiring corporation refuses to assume such
Options or to substitute similar Options for those outstanding under the Plan,
then with respect to Options held by Optionees whose Continuous Service has not
terminated, the vesting shall be accelerated in full, and the Options shall
terminate if not exercised at or prior to such event. With respect to any other
Options outstanding under the Plan, such Options shall terminate if not
exercised prior to such event.

     (c) In the event of either (i) the acquisition by any person, entity or
group within the meaning of Section 13(d) or 14(d) of the Exchange Act or any
comparable successor provisions (excluding any employee benefit plan, or related
trust, sponsored or maintained by the Company or an Affiliate of the Company) of
the beneficial ownership (within the meaning of Rule 13d-3 promulgated under the
Exchange Act, or comparable successor rule) of securities of the Company
representing at least fifty percent (50%) of the combined voting power entitled
to vote in the election of directors, which acquisition has not been approved by
resolution of the Company's Board of Directors, or (ii) a change in a majority
of the membership of the Company's Board of Directors within a twenty-four (24)
month period where the selection of such majority either (A) was not approved by
a majority of the members of the Board of Directors at the beginning of such
twenty-four (24) month period or (B) occurred as the result of an actual or
threatened "Election Contest" (as described in Rule 14a-11 promulgated under the
Exchange Act) or other actual or threatened solicitation of proxies or consents
by or on behalf of


                                      7
<PAGE>

any person other than the Board (a "Proxy Contest"), including by reason of
any agreement intended to avoid or settle any Election Contest or Proxy
Contest, then to the extent not prohibited by applicable law, the time during
which options outstanding under the Plan may be exercised shall be
accelerated prior to such event, but only to the extent that such options
would have become exercisable within thirty (30) months of the date of such
event, and the options terminated if not exercised after such acceleration
and at or prior to such event.

12.  TIME OF GRANTING OPTIONS.

     The date of grant of an Option shall, for all purposes, be the date on
which the Board makes the determination granting such Option. Notice of the
determination shall be given to each Employee or Consultant to whom an Option
is so granted within a reasonable time after the date of such grant.

13.  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) EFFECT OF AMENDMENT OR TERMINATION. Options granted before amendment of
the Plan shall not be impaired any amendment unless mutually agreed otherwise
between the Optionee and the Company, which agreement must be in writing and
signed by the Optionee and the Company.

14.  SECURITIES LAW COMPLIANCE.

     Notwithstanding any provisions relating to vesting contained herein or
in an Option, no Option granted hereunder may be exercised unless the shares
issuable upon exercise of such option are then registered under the
Securities Act of 1933, as amended.

15.  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.

     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.

16.  OPTION AGREEMENT.

     Options shall be evidenced by written Option Agreements in such form or
forms as the Board or the Committee shall approve.
