such resolutions, not inconsistent with the provisions of the Plan, as may be
adopted from time to time by the Board. The Board may abolish the Committee at
any time and revest in the Board the administration of the Plan.

4.   SHARES SUBJECT TO THE PLAN.

     (a)  Subject to the provisions of Section 12 relating to adjustments upon
changes in stock, the stock that may be issued pursuant to Stock Awards shall
not exceed in the aggregate Five Million Six Hundred Fifty Thousand (5,650,000)
shares of Common Stock. If any Stock Award shall for any reason expire or
otherwise terminate, in whole or in part, without having been exercised in full
(or vested in the case of Restricted Stock), the stock not acquired under such
Stock Award shall revert to and again become available for issuance under the
Plan.

     (b)  The stock subject to the Plan may be unissued shares or reacquired
shares, bought on the market or otherwise.

total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Option is at


                                       4.

   5

least one hundred ten percent (110%) of the Fair Market Value of such stock at
the date of grant and the Option is not exercisable after the expiration of five
(5) years from the date of grant.

     (c)  Subject to the provisions of Section 12 relating to adjustments upon
changes in stock, no person shall be eligible to be granted Options covering
more than Two Hundred Eighty Thousand (280,000) shares of the Common Stock in
any calendar year. This subsection 5(c) shall not apply until (i) the earliest

the number of shares reserved for issuance under the Plan in accordance with
Section 4); (B) the issuance of all of the shares of Common Stock reserved for
issuance under the Plan; (C) the expiration of the Plan; or (D) the first
meeting of stockholders at which directors are to be elected that occurs after
the close of the third calendar year following the calendar year in which
occurred the first registration of an equity security under Section 12 of the
Exchange Act; or (ii) such other date required by Section 162(m) of the Code and
the rules and regulations promulgated thereunder.

6.   OPTION PROVISIONS.

     Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions:

     (a)  TERM. No Option shall be exercisable after the expiration of ten (10)
years from the date it was granted.

     (b)  PRICE. The exercise price of each Incentive Stock Option shall be not
less than one hundred percent (100%) of the Fair Market Value of the stock
subject to the Option on the date the Option is granted and the exercise price
of each Nonstatutory Stock Option shall be not less than eighty-five percent
(85%) of the Fair Market Value of the stock subject to the Option on the date
the Option is granted. 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.

     (c)  CONSIDERATION. The purchase price of stock acquired pursuant to an
Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised, or (ii) at
the discretion of the Board or the Committee, at the time of the grant of the
Option, (A) by delivery to the Company of other Common Stock of the Company, (B)
according to a deferred payment or other arrangement (which may include, without
limiting the generality of the foregoing, the use of other Common Stock of the
Company) with the person to whom the Option is granted or to whom the Option is
transferred pursuant to subsection 6(d), or (C) in any other form of legal
consideration that may be acceptable to the Board.

     In the case of any deferred payment arrangement, interest shall be payable
at least annually and shall be charged at the minimum rate of interest necessary
to avoid the treatment as


                                       5.

   6

interest, under any applicable provisions of the Code, of any amounts other than
amounts stated to be interest under the deferred payment arrangement.

     (d)  TRANSFERABILITY. An Incentive Stock Option shall not be transferable
except by will or by the laws of descent and distribution, and shall be
exercisable during the lifetime of the person to whom the Incentive Stock Option
is granted only by such person. A Nonstatutory Stock Option may be transferred
to the extent provided in the Option Agreement; provided that if the Option
Agreement does not expressly permit the transfer of a Nonstatutory Stock Option,
the Nonstatutory Stock Option shall not be transferable except by will, by the
laws of descent and distribution or pursuant to a domestic relations order
satisfying the requirements of Rule 16b-3 and shall be exercisable during the
lifetime of the person to whom the Option is granted only by such person or any
transferee pursuant to a domestic relations order. Notwithstanding the
foregoing, the person to whom the Option is granted may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionee, shall thereafter be
entitled to exercise the Option.

     (e)  VESTING. The total number of shares of stock 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
subsection 6(e) are subject to any Option provisions governing the minimum
number of shares as to which an Option may be exercised.

     (f)  TERMINATION OF EMPLOYMENT OR RELATIONSHIP AS A DIRECTOR OR CONSULTANT.
In the event an Optionee's Continuous Status as an Employee, Director or
Consultant terminates (other than upon the Optionee's death or disability), the
Optionee may exercise his or her Option (to the extent that the Optionee was
entitled to exercise it at the date of termination) but only within such period
of time ending on the earlier of (i) the date three (3) months after the
termination of the Optionee's Continuous Status as an Employee, Director or
Consultant (or such longer or shorter period specified in the Option Agreement),
or (ii) the expiration of the term of the Option as set forth in the Option
Agreement. If, after termination, the Optionee does not exercise his or her
Option within the time specified in the Option Agreement, the Option shall
terminate, and the shares covered by such Option shall revert to and again
become available for issuance under the Plan.

     An Optionee's Option Agreement may also provide that if the exercise of the
Option following the termination of the Optionee's Continuous Status as an
Employee, Director or Consultant (other than upon the Optionee's death or
disability) would be prohibited at any time solely because the issuance of
shares would violate the registration requirements under the Act, then the
Option shall terminate on the earlier of (i) the expiration of the term of the
Option set forth in the first paragraph of this subsection 6(f), or (ii) the
expiration of a period of three (3) months after the termination of the
Optionee's Continuous Status as an Employee, Director or


                                       6.

   7

Consultant during which the exercise of the Option would not be in violation of
such registration requirements.

     (g)  DISABILITY OF OPTIONEE. In the event an Optionee's Continuous Status
as an Employee, Director or Consultant terminates as a result of the Optionee's
disability, the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise it at the date of termination), but only
within such period of time ending on the earlier of (i) the date twelve (12)
months following such termination (or such longer or shorter period specified in
the Option Agreement), or (ii) the expiration of the term of the Option as set
forth in the Option Agreement. 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 and again become available
for issuance under 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 and again
become available for issuance under the Plan.

     (h)  DEATH OF OPTIONEE. In the event of the death of an Optionee during, or
within a period specified in the Option after the termination of, the Optionee's
Continuous Status as an Employee, Director or Consultant, the Option may be
exercised (to the extent the Optionee was entitled to exercise the Option at the
date of death) by the Optionee's estate, by a person who acquired the right to
exercise the Option by bequest or inheritance or by a person designated to
exercise the option upon the Optionee's death pursuant to subsection 6(d), but
only within the period ending on the earlier of (i) the date eighteen (18)
months following the date of death (or such longer or shorter period specified
in the Option Agreement), or (ii) the expiration of the term of such Option as
set forth in the Option Agreement. 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 and again become available
for issuance under the Plan. If, after death, the Option is not exercised within
the time specified herein, the Option shall terminate, and the shares covered by
such Option shall revert to and again become available for issuance under the
Plan.

     (i)  EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time while an Employee, Director or
Consultant to exercise the Option as to any part or all of the shares subject to
the Option prior to the full vesting of the Option. Any unvested shares so
purchased may be subject to a repurchase right in favor of the Company or to any
other restriction the Board determines to be appropriate.

     (j)  RE-LOAD OPTIONS. Without in any way limiting the authority of the
Board or Committee to make or not to make grants of Options hereunder, the Board
or Committee shall have the authority (but not an obligation) to include as part
of any Option Agreement a provision entitling the Optionee to a further Option
(a "Re-Load Option") in the event the Optionee exercises the Option evidenced by
the Option Agreement, in whole or in part, by surrendering other shares of
Common Stock in accordance with this Plan and the terms and conditions of the
Option Agreement. Any such Re-Load Option (i) shall be for a number of shares
equal to the number of shares surrendered as part or all of the exercise price
of such Option; (ii) shall have an expiration date which is the same as the
expiration date of the Option the exercise of which gave rise to such Re-Load
Option; and (iii) shall have an exercise price which is equal to one hundred


                                       7.

   8

percent (100%) of the Fair Market Value of the Common Stock subject to the
Re-Load Option on the date of exercise of the original Option. Notwithstanding
the foregoing, a Re-Load Option which is an Incentive Stock Option and which is
granted to a 10% stockholder (as described in subsection 5(b)), shall have an
exercise price which is equal to one hundred ten percent (110%) of the Fair
Market Value of the stock subject to the Re-Load Option on the date of exercise
of the original Option and shall have a term which is no longer than five (5)
years.

     Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Board or Committee may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollars ($100,000) annual limitation on exercisability of Incentive Stock
Options described in subsection 11(d) of the Plan and in Section 422(d) of the
Code. There shall be no Re-Load Options on a Re-Load Option. Any such Re-Load
Option shall be subject to the availability of sufficient shares under
subsection 4(a) and shall be subject to such other terms and conditions as the
Board or Committee may determine which are not inconsistent with the express
provisions of the Plan regarding the terms of Options.

7.   TERMS OF STOCK BONUSES AND PURCHASES OF RESTRICTED STOCK.

     Each stock bonus or restricted stock purchase agreement shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus or
restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions as appropriate:

     (a)  PURCHASE PRICE. The purchase price under each restricted stock
purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such agreement, but in no event shall the purchase
price be less than eighty-five percent (85%) of the stock's Fair Market Value on
the date such award is made. Notwithstanding the foregoing, the Board or the
Committee may determine that eligible participants in the Plan may be awarded
stock pursuant to a stock bonus agreement in consideration for past services
actually rendered to the Company for its benefit.

     (b)  TRANSFERABILITY. No rights under a stock bonus or restricted stock
purchase agreement shall be transferable except by will or the laws of descent
and distribution or, if the agreement so provides, pursuant to a domestic
relations order satisfying the requirements of Rule 16b-3 so long as stock
awarded under such agreement remains subject to the terms of the agreement.

     (c)  CONSIDERATION. The purchase price of stock acquired pursuant to a
stock purchase agreement shall be paid either: (i) in cash at the time of
purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment or other arrangement with the person to whom the stock is sold;
or (iii) in any other form of legal consideration that may be acceptable to the
Board or the Committee in its discretion. Notwithstanding the foregoing, the
Board or the Committee to which administration of the Plan has been delegated
may award stock


                                       8.

   9

pursuant to a stock bonus agreement in consideration for past services actually
rendered to the Company or for its benefit.

     (d)  VESTING. Shares of stock sold or awarded under the Plan may, but need
not, be subject to a repurchase option in favor of the Company in accordance
with a vesting schedule to be determined by the Board or the Committee.

     (e)  TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. In the event a Participant's Continuous Status as an Employee,
Director or Consultant terminates, the Company may repurchase or otherwise
reacquire any or all of the shares of stock held by that person which have not
vested as of the date of termination under the terms of the stock bonus or
restricted stock purchase agreement between the Company and such person.

8.   CANCELLATION AND RE-GRANT OF OPTIONS.

     (a)  The Board or the Committee shall have the authority to effect, at any
time and from time to time, (i) the repricing of any outstanding Options under
the Plan and/or (ii) with the consent of any adversely affected holders of
Options, the cancellation of any outstanding Options under the Plan and the
grant in substitution therefor of new Options under the Plan covering the same
or different numbers of shares of stock, but having an exercise price per share
not less than eighty-five percent (85%) of the Fair Market Value for a
Nonstatutory Stock Option, one hundred percent (100%) of the Fair Market Value
for an Incentive Stock Option or, in the case of an Incentive Stock Option held
by a 10% stockholder (as described in subsection 5(b)), not less than one
hundred ten percent (110%) of the Fair Market Value per share of stock on the
new grant date. Notwithstanding the foregoing, the Board or the Committee may
grant an Option with an exercise price lower than that set forth above if such
Option is granted as part of a transaction to which section 424(a) of the Code
applies.

     (b)  Shares subject to an Option canceled under this Section 8 shall
continue to be counted against the maximum award of Options permitted to be
granted pursuant to subsection 5(c) of the Plan. The repricing of an Option
under this Section 8, resulting in a reduction of the exercise price, shall be
deemed to be a cancellation of the original Option and the grant of a substitute
Option; in the event of such repricing, both the original and the substituted
Options shall be counted against the maximum awards of Options permitted to be
granted pursuant to subsection 5(c) of the Plan. The provisions of this
subsection 8(b) shall be applicable only to the extent required by Section
162(m) of the Code.

9.   COVENANTS OF THE COMPANY.

     (a)  During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock
Awards.

     (b)  The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares under Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
of 1933, as amended (the "Securities Act") either the Plan, any Stock Award or
any stock issued or issuable pursuant to any such Stock Award. If, after
reasonable efforts, the Company is unable to obtain from any such regulatory
commission or agency the


                                       9.

   10

authority which counsel for the Company deems necessary for the lawful issuance
and sale of stock under the Plan, the Company shall be relieved from any
liability for failure to issue and sell stock upon exercise of such Stock Awards
unless and until such authority is obtained.

10.  USE OF PROCEEDS FROM STOCK.

     Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.

11.  MISCELLANEOUS.

     (a)  The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any part
thereof will vest pursuant to subsection 6(e) or 7(d), notwithstanding the
provisions in the Stock Award stating the time at which it may first be
exercised or the time during which it will vest.

     (b)  Neither an Employee, Director nor a Consultant nor any person to whom
a Stock Award is transferred in accordance with the Plan shall be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any
shares subject to such Stock Award unless and until such person has satisfied
all requirements for exercise of the Stock Award pursuant to its terms.

     (c)  Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Consultant or other holder of
Stock Awards any right to continue in the employ of the Company or any Affiliate
or to continue serving as a Consultant and Director, or shall affect the right
of the Company or any Affiliate to terminate the employment of any Employee with
or without notice and with or without cause, or the right to terminate the
relationship of any Consultant pursuant to the terms of such Consultant's
agreement with the Company or Affiliate or service as a Director pursuant to the
Company's By-laws.

     (d)  To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand dollars
($100,000), the Options or portions thereof which exceed such limit (according
to the order in which they were granted) shall be treated as Nonstatutory Stock
Options.

     (e)  The Company may require any person to whom a Stock Award is granted,
or any person to whom a Stock Award is transferred in accordance with the Plan,
as a condition of exercising or acquiring stock under any Stock Award, (1) to
give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person is
acquiring the stock subject to the Stock Award for such person's own account and
not with any present intention of selling or otherwise distributing the stock.
The foregoing


                                      10.

   11

requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (i) the issuance of the shares upon the exercise or acquisition
of stock under the Stock Award has been registered under a then currently
effective registration statement under the Securities Act, or (ii) as to any
particular requirement, a determination is made by counsel for the Company that
such requirement need not be met in the circumstances under the then applicable
securities laws. The Company may, upon advice of counsel to the Company, place
legends on stock certificates issued under the Plan as such counsel deems
necessary or appropriate in order to comply with applicable securities laws,
including, but not limited to, legends restricting the transfer of the stock.

     (f)  To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of stock
under a Stock Award by any of the following means or by a combination of such
means: (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the Common Stock otherwise issuable to the participant
as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the Common Stock
of the Company.

12.  ADJUSTMENTS UPON CHANGES IN STOCK.

     (a)  If any change is made in the stock subject to the Plan, or subject to
any Stock Award, 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 will be appropriately adjusted in the class(es) and maximum
number of shares subject to the Plan pursuant to subsection 4(a) and the maximum
number of shares subject to award to any person during any calendar year
pursuant to subsection 5(c), and the outstanding Stock Awards will be
appropriately adjusted in the class(es) and number of shares and price per share
of stock subject to such outstanding Stock Awards. Such adjustments shall be
made by the Board or the Committee, the determination of which shall be final,
binding and conclusive. (The conversion of any convertible securities of the
Company shall not be treated as a "transaction not involving the receipt of
consideration by the Company".)

     (b)  In the event of: (1) a dissolution, liquidation or sale of
substantially all of the assets 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 to the extent permitted by applicable law: (i) any
surviving corporation or a parent of such surviving corporation shall assume any
Stock Awards outstanding under the Plan or shall substitute similar Stock Awards
for those outstanding under the Plan, or (ii) such Stock Awards shall continue
in full force and effect. In the event any surviving corporation or its parent
refuses to assume or continue such Stock Awards, or to substitute similar Stock
Awards for those outstanding under the Plan, then, with respect to Stock Awards
held by persons then performing services as Employees, Directors or Consultants,
the time during which such Stock


                                      11.

   12

Awards may be exercised shall be accelerated, the vesting of such Stock Awards
shall be accelerated if so determined by the Board and the Stock Awards
terminated if not exercised prior to such event.

13.  AMENDMENT OF THE PLAN AND STOCK AWARDS.

     (a)  The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 12 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the stockholders of
the Company to the extent stockholder approval is necessary for the Plan to
satisfy the requirements of Section 422 of the Code, Rule 16b-3 or any Nasdaq or
securities exchange listing requirements.

     (b)  The Board may in its sole discretion submit any other amendment to the
Plan for stockholder approval, including, but not limited to, amendments to the
Plan intended to satisfy the requirements of Section 162(m) of the Code and the
regulations thereunder regarding the exclusion of performance-based compensation
from the limit on corporate deductibility of compensation paid to certain
executive officers.

     (c)  It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible Employees,
Directors or Consultants with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

     (d)  Rights under any Stock Award granted before amendment of the Plan
shall not be impaired by any amendment of the Plan unless (i) the Company
requests the consent of the person to whom the Stock Award was granted and (ii)
such person consents in writing.

     (e)  The Board at any time, and from time to time, may amend the terms of
any one or more Stock Awards; provided, however, that the rights under any Stock
Award shall not be impaired by any such amendment unless (i) the Company
requests the consent of the person to whom the Stock Award was granted and (ii)
such person consents in writing.

14.  TERMINATION OR SUSPENSION OF THE PLAN.

     (a)  The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate ten (10) years from the date the Plan is
adopted by the Board or approved by the stockholders of the Company, whichever
is earlier. No Stock Awards may be granted under the Plan while the Plan is
suspended or after it is terminated.

     (b)  Rights and obligations under any Stock Award granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan, except
with the consent of the person to whom the Stock Award was granted.

15.  EFFECTIVE DATE OF PLAN.

     The Plan shall become effective on the date adopted by the Board, but no
Stock Awards granted under the Plan shall be exercised unless and until the Plan
has been approved by the


                                      12.

   13

stockholders of the Company, which approval shall be within twelve (12) months
before or after the date the Plan is adopted by the Board.
