that such Share Reserve shall be increased on January 1 of each year, beginning
with January 1, 1999, by an amount equal to three percent (3%) of the total
outstanding shares of Common Stock (calculated on a fully diluted, fully

acquired under such Stock Award shall revert to and again become available for
issuance under the Plan.  Shares subject to stock appreciation rights exercised
in accordance with the Plan shall not be available for subsequent issuance under
the Plan.  If any shares of Common Stock acquired pursuant to the exercise of an

repurchase option provided under the Plan, the stock repurchased by the Company
under such repurchase option shall revert to and again become available for
issuance under the Plan.

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

5.   ELIGIBILITY.

     (a)  Incentive Stock Options may be granted only to Employees.  Stock
Awards other than Incentive Stock Options may be granted only to Employees,
Directors or Consultants.

     (b)  No person shall be eligible for the grant of an Incentive Stock Option
if, at the time of grant, such person owns (or is deemed to own pursuant to
Section 424(d) of the Code) stock possessing more than ten percent (10%) of the
total combined voting power of all classes of stock of the Company or of any of
its Affiliates unless the exercise price of such Incentive


                                          5
<PAGE>

Stock Option is at least one hundred ten percent (110%) of the Fair Market Value
of such stock at the date of grant and the Incentive Stock 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 one million (1,000,000) shares of Common Stock in any calendar year.
This subsection 5(c) shall not apply prior to the Listing Date and, following

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

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.  All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and a separate certificate or certificates will be issued for shares
purchased on exercise of each type of Option.  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 Incentive Stock Option on the date the Incentive Stock Option is
granted or such greater amount as required by Section 5(b).  The exercise price
of each Nonstatutory Stock Option shall be determined by the Board.
Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a
Nonstatutory Stock 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 at the time the Option is exercised, to the extent
permitted by applicable statutes and regulations, either (i) in cash or by check
or (ii) at the discretion of the Board, at the time of the grant of the Option,
under one of the following alternatives:

          (1)  Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in THE WALL STREET JOURNAL, 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


                                          6
<PAGE>

irrevocable instructions to pay the aggregate exercise price to the Company from
the sales proceeds;

          (2)  Provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in THE WALL STREET JOURNAL, by delivery of
already-owned shares of Common Stock, held for the period required to avoid a
charge to the Company's reported earnings, and owned free and clear of any
liens, claims, encumbrances or security interests, which Common Stock shall be
valued at its fair market value on the date of exercise;

          (3)  Pursuant to a deferred payment alternative as described in the
Option Agreement, PROVIDED THAT, at any time that the Company is incorporated in
Delaware, payment of the Common Stock's "par value" (as defined in the Delaware
General Corporation Law) shall not be made by deferred payment;

          (4)  In any other form of legal consideration that may be acceptable
to the Board; or

          (5)  By any combination of the above methods.

     (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 Option is granted only
by such person.  A Nonstatutory Stock Option may be transferable to the extent
expressly provided in the Option Agreement; PROVIDED, HOWEVER, that if the
Option Agreement does not specifically provide for transferability, then such
Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution or pursuant to a domestic relations order, and
shall be exercisable during the lifetime of the person to whom the Nonstatutory
Stock 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
shall vest and become exercisable as provided in the Option Agreement.

     (f)  TERMINATION OF CONTINUOUS SERVICE.  In the event an Optionee's
Continuous Service 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 Service (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 provided, however, if the
Optionee is terminated for Cause, then the Option shall terminate on the date
Optionee's Continuous Service ceases (or such longer period specified 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.


                                          7
<PAGE>

     An Optionee's Option Agreement may also provide that if the exercise of the
Option following the termination of the Optionee's Continuous Service (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 Securities Act or any material regulatory requirements of
any foreign jurisdiction, then the Option shall terminate on the earlier of (i)
the expiration of the term of the Option as set forth in the Option Agreement,
or (ii) the expiration of a period of three (3) months after the termination of
the Optionee's Continuous Service 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 Service
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, taking into account any post-termination amendments
to the Option Agreement), 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 the entire
Option, the shares covered by the unexercisable portion of the Option shall
revert to and again become available for issuance under the Plan no later than
thirty (30) days following the date of termination.  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 the three (3) month or twelve (12) month periods referred to above
after the termination of, the Optionee's Continuous Service, the Option may be
exercised (to the extent the Optionee was entitled to exercise the Option at the
date of death, taking into account any post-termination amendments to the Option
Agreement) 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 the entire Option, the shares covered by the
unexercisable portion of the Option shall revert to and again become available
for issuance under the Plan no later than thirty (30) days following the date of
termination.  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 before the Optionee's Continuous
Service terminates 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 shall be subject to a repurchase right in favor of the
Company or any other restriction the Board determines 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


                                          8
<PAGE>

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 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
shall be subject to the same exercise price and term provisions heretofore
described for Options under the Plan.

     Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Board 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 dollar
($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 the "Section 162(m) Limitation" or grants of Options under subsection 5(c)
and shall be subject to such other terms and conditions as the Board 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.

     (a)  Each stock bonus or restricted stock purchase agreement shall be in
such form and shall contain such terms and conditions as the Board 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:

          (1)  PURCHASE PRICE.  The purchase price under each restricted stock
purchase agreement shall be such amount as the Board 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 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.

          (2)  TRANSFERABILITY.  A stock bonus or restricted stock purchase
agreement may be transferable to the extent expressly provided in the Stock
Award Agreement; PROVIDED, HOWEVER, that if the Stock Award Agreement does not
specifically provide for transferability, then such stock bonus or restricted
stock purchase award shall not be transferable except by will or the laws of
descent and distribution or pursuant to a domestic relations order, and shall be
exercisable during the lifetime of the person to whom the stock bonus or
restricted stock


                                          9
<PAGE>

purchase award is granted only by such person or any transferee pursuant to a
domestic relations order, so long as stock awarded under such agreement remains
subject to any restrictions pursuant to the agreement.

          (3)  CONSIDERATION.  The purchase price of stock acquired pursuant to
a restricted stock purchase agreement shall be paid either:  (i) in cash at the
time of purchase; (ii) at the discretion of the Board, 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 in
its discretion.  Notwithstanding the foregoing, the Board may award stock
pursuant to a stock bonus agreement in consideration for past services actually
rendered to the Company or for its benefit.

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

          (5)  TERMINATION OF CONTINUOUS SERVICE.  In the event a Participant's
Continuous Service 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, subject to the
provisions of Section 12.

          (6)  STOCK APPRECIATION RIGHTS.

               (i)  AUTHORIZED RIGHTS.  The following three types of stock
appreciation rights shall be authorized for issuance under the Plan:

                    a.   TANDEM RIGHTS.  A "Tandem Right" means a stock
appreciation right granted appurtenant to an Option which is subject to the same
terms and conditions applicable to the particular Option grant to which it
pertains with the following exceptions:  The Tandem Right shall require the
holder to elect between the exercise of the underlying Option for shares of
Common Stock and the surrender, in whole or in part, of such Option for an
appreciation distribution.  The appreciation distribution payable on the
exercised the Tandem Right shall be in cash (or, if so provided, in an
equivalent number of shares of Common Stock based on Fair Market Value on the
date of the Option surrender) in an amount up to the excess of (A) the Fair
Market Value (on the date of the Option surrender) of the number of shares of
Common Stock covered by that portion of the surrendered Option in which the
Optionee is vested over (B) the aggregate exercise price payable for such vested
shares.

                    b.   CONCURRENT RIGHTS.  A "Concurrent Right" means a stock
appreciation right granted appurtenant to an Option which applies to all or a
portion of the shares of Common Stock subject to the underlying Option and which
is subject to the same terms and conditions applicable to the particular Option
grant to which it pertains with the following exceptions:  A Concurrent Right
shall be exercised automatically at the same time the underlying Option is
exercised with respect to the particular shares of Common Stock to which the
Concurrent Right pertains.  The appreciation distribution payable on an
exercised Concurrent Right shall be in cash (or, if so provided, in an
equivalent number of shares of Common Stock


                                          10
<PAGE>

based on Fair Market Value on the date of the exercise of the Concurrent Right)
in an amount equal to such portion as determined by the Board at the time of the
grant of the excess of (A) the aggregate Fair Market Value (on the date of the
exercise of the Concurrent Right) of the vested shares of Common Stock purchased
under the underlying Option which have Concurrent Rights appurtenant to them
over (B) the aggregate exercise price paid for such shares.

                    c.   INDEPENDENT RIGHTS.  An "Independent Right" means a
stock appreciation right granted independently of any Option but which is
subject to the same terms and conditions applicable to a Nonstatutory Stock
Option with the following exceptions:  An Independent Right shall be denominated
in share equivalents.  The appreciation distribution payable on the exercised
Independent Right shall be not greater than an amount equal to the excess of (a)
the aggregate Fair Market Value (on the date of the exercise of the Independent
Right) of a number of shares of Common Stock equal to the number of share
equivalents in which the holder is vested under such Independent Right, and with
respect to which the holder is exercising the Independent Right on such date,
over (b) the aggregate Fair Market Value (on the date of the grant of the
Independent Right) of such number of shares of Common Stock.  The appreciation
distribution payable on the exercised Independent Right shall be in cash or, if
so provided, in an equivalent number of shares of Common Stock based on Fair
Market Value on the date of the exercise of the Independent Right.

               (II)      RELATIONSHIP TO OPTIONS.  Stock appreciation rights
appurtenant to Incentive Stock Options may be granted only to Employees.  The
"Section 162(m) Limitation" provided in subsection 5(c) and any authority to
reprice Options shall apply as well to the grant of stock appreciation rights.

               (III)     EXERCISE.  To exercise any outstanding stock
appreciation right, the holder shall provide written notice of exercise to the
Company in compliance with the provisions of the Stock Award Agreement
evidencing such right.   Except as provided in subsection 5(c) regarding the
"Section 162(m) Limitation," no limitation shall exist on the aggregate amount
of cash payments that the Company may make under the Plan in connection with the
exercise of a stock appreciation right.

8.   CANCELLATION AND RE-GRANT OF OPTIONS.

     (A)  The Board shall have the authority to effect, at any time and from
time to time,  (i) the repricing of any outstanding Options and/or (ii) with the
consent of the 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 Common Stock.
The exercise price per share shall be not less than that specified under the
Plan for newly granted Stock Awards.  Notwithstanding the foregoing, the Board
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


                                          11
<PAGE>

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 Section 8 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
grant Stock Awards and to issue and sell shares of Common Stock upon exercise of
the Stock Awards; provided, however, that this undertaking shall not require the
Company to register under the Securities Act 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 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, 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)  No Optionee 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 Optionee any right to continue in the
employ of the Company or any Affiliate (or to continue acting as a Director or
Consultant) or shall affect the right of the Company or any Affiliate to
terminate the employment of any Employee with or without Cause, the right of the
Company's Board of Directors and/or the Company's stockholders to remove any
Director pursuant to the terms of the Company's Bylaws and the provisions of
applicable laws, or the right to terminate the relationship of any Consultant
pursuant to the terms of such Consultant's agreement with the Company or
Affiliate to which such Consultant is providing services.


                                          12

     (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 pursuant to subsection 6(d)
or 7(a)(2), 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 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 require the Optionee to
provide such other representations, written assurances or information which the
Company shall determine is necessary, desirable or appropriate to comply with
applicable securities and other laws as a condition of granting an Option to
such Optionee or permitting the Optionee to exercise such Option.  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
Optionee 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 (in addition to the
Company's right to withhold from any compensation paid to the Optionee by the
Company):  (1) tendering a cash payment; (2) authorizing the Company to withhold
shares from the shares of the Common Stock otherwise issuable to the Optionee 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


                                          13
<PAGE>

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 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, 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 a Change in Control (as defined herein) any surviving
corporation or acquiring corporation shall assume any Stock Awards outstanding
under the Plan or shall substitute similar stock awards (including an award to
acquire the same consideration paid to the shareholders in the transaction
described in this subsection 12(b)) for those outstanding under the Plan.  In
the event any surviving or acquiring corporation refuses to assume such Stock
Awards or to substitute similar stock awards for those outstanding under the
Plan, then with respect to persons whose Continuous Service has not terminated
prior to such Change in Control: (i) the vesting (and, if applicable, the
exercisability) of Stock Awards held by such persons shall be accelerated
immediately prior to such event, and the Stock Awards terminated if not
exercised at or prior to such event, and (ii) any Company repurchase option or
reacquisition right with respect to shares acquired by such persons under a
Stock Award shall lapse immediately prior to such event and the shares held by
such persons shall be fully vested. With respect to any other Stock Awards
outstanding under the Plan, such Stock Awards shall terminate if not exercised
prior to such event.

     In addition, and only if explicitly provided for in the Stock Award
Agreement, with respect to any person whose Continuous Service has not
terminated prior to the consummation of a Change in Control, if upon or within
twenty-four (24) months following a Change in Control one of the following
events occurs:  (i) such person's Continuous Service is terminated by the
acquiror or successor without Cause; (ii) the principal place of the performance
of such person's responsibilities (the "Principal Location") is changed to a
location more than twenty-five (25) miles from such person's Principal Location
immediately prior to the Change in Control and such person voluntarily
terminates Continuous Service with the successor or acquiror; or (iii) there is
a material reduction in such person's compensation or responsibilities (not
involving a termination of Continuous Service for Cause) and such person
voluntarily terminates Continuous Service with the successor or acquirer; then
the unvested portion of such person's Options shall immediately become fully
vested and exercisable and any Company repurchase option or reacquisition right
with respect to shares acquired by such persons under a Stock Award shall
immediately lapse and the shares held by such persons shall be fully vested. The
Board shall have the ability to alter the terms of this paragraph with respect
to one or more Stock Award Agreements in its sole discretion.

     For purposes of this subsection 12(b), Cause shall be defined to include
(in addition to those items set forth in Section 2(c)) death and physical or
mental disability.

     For purposes of this Plan, a "Change in Control" shall mean:  (i) a sale of
all or substantially all of the assets of the Company; (ii) a merger or
consolidation in which the Company is not the surviving corporation or a reverse
merger in which the Company is the


                                          14
<PAGE>

surviving corporation but the shares of the 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 (other than (a) a merger or
consolidation in which stockholders immediately before the merger or
consolidation have, immediately after the merger or consolidation, greater stock
voting power of the acquiring or controlling corporation, and in no event less
than a majority of such stock voting power, (b) a transaction the principal
purpose of which is to change the State of the Company's incorporation, or (c) a
merger of the Company into any of its wholly owned subsidiaries); or (iii) an
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 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.

     (C)  In the event of a dissolution or liquidation of the Company, any Stock
Awards outstanding under the Plan shall terminate 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 promulgated 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 Optionees 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 and obligations 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.


                                          15

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 on the day before the tenth (10th)
anniversary of 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 as of the Listing Date, but no Stock Awards
granted under the Plan shall be exercised (or, in the case of a stock bonus,
shall be granted) unless and until the Plan has been approved by the
stockholders of the Company, which approval shall be within twelve (12) months
before or after the date the Plan is adopted by the Board.

16.  CHOICE OF LAW.

     All questions concerning the construction, validity and interpretation of
this Plan shall be governed by the law of the State of Delaware, without regard
to such state's conflict of laws rules.
