in cash at the time the Option is exercised or (ii) at the discretion of the
Board at the time of the grant of the Option (or subsequently in the case of a
Nonstatutory Stock Option) (1) by delivery to the Company (either by actual
delivery or attestation) of other Common Stock at the time the Option is
exercised, (2) according to a deferred payment or other similar arrangement with
the Optionholder, (3) by a "net exercise" of the Option (as further described
below), (4) pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board that, 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 or (5) in any other form of legal consideration that may be
acceptable to the Board. Unless otherwise specifically provided in the Option,
the purchase price of Common Stock acquired pursuant to an Option that is paid
by delivery to the Company of other Common Stock acquired, directly or
indirectly from the Company, shall be paid only by shares of the Common Stock of
the Company that have been held for more than six (6) months (or such longer or
shorter period of time required to avoid a charge to earnings for financial
accounting purposes). 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.
 
      In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid (1) the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement and (2) the treatment of the Option as a
variable award for financial accounting purposes.
 
      In the case of a "net exercise" of an Option, the Company will not require
a payment of the exercise price of the Option from the Participant but will
reduce the number of shares of Common Stock issued upon the exercise by the
largest number of whole shares that has a Fair Market Value that does not exceed
the aggregate exercise price. With respect to any remaining balance of the
aggregate exercise price, the Company shall accept a cash payment from the
Participant. Shares of Common Stock will no longer be outstanding under an
Option (and will therefore not thereafter be exercisable) following the exercise
of such Option to the extent of (i) shares used to pay the exercise price of an
Option under the "net exercise", (ii) shares actually delivered to the
Participant as a result of such exercise and (iii) shares withheld for purposes
of tax withholding.
 
                                      11.
<PAGE>
      (E) TRANSFERABILITY OF AN INCENTIVE STOCK OPTION. 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 Optionholder
only by the Optionholder. Notwithstanding the foregoing, the Optionholder may,
by delivering written notice to the Company, in a form provided by or otherwise
satisfactory to the Company, designate a third party who, in the event of the
death of the Optionholder, shall thereafter be entitled to exercise the Option.
 
      (F) TRANSFERABILITY OF A NONSTATUTORY STOCK OPTION. A Nonstatutory Stock
Option shall be transferable to the extent provided in the Option Agreement. If
the Nonstatutory Stock Option does not provide for transferability, then the
Nonstatutory 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 Optionholder only by the Optionholder. Notwithstanding the foregoing, the
Optionholder may, by delivering written notice to the Company, in a form
provided by or otherwise satisfactory to the Company, designate a third party
who, in the event of the death of the Optionholder, shall thereafter be entitled
to exercise the Option.
 
      (G) VESTING GENERALLY. The total number of shares of Common Stock subject
to an Option may, but need not, vest and therefore become exercisable in
periodic installments that may, but need not, be equal. 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 vesting provisions of individual Options may vary. The
provisions of this Section 6(g) are subject to any Option provisions governing
the minimum number of shares of Common Stock as to which an Option may be
exercised.
 
      (H) TERMINATION OF CONTINUOUS SERVICE. In the event that an Optionholder's
Continuous Service terminates (for reasons other than Cause or upon the
Optionholder's death or Disability), the Optionholder may exercise his or her
Option (to the extent that the Optionholder was entitled to exercise such Option
as of the date of termination) but only within such period of time ending on the
earlier of (i) the date three (3) months following the termination of the
Optionholder'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. If, after termination of Continuous Service, the
Optionholder does not exercise his or her Option within the time specified
herein or in the Option Agreement (as applicable), the Option shall terminate.
 
      (I) EXTENSION OF TERMINATION DATE. An Optionholder's Option Agreement may
also provide that if the exercise of the Option following the termination of the
Optionholder's Continuous Service (for reasons other than Cause or upon the
Optionholder's death or Disability) would be prohibited at any time solely
because the issuance of shares of Common Stock would violate the registration
requirements under the Securities Act, then the Option shall terminate on the
earlier of (i) the expiration of the term of the Option set forth in the Option
Agreement or (ii) the expiration of a period of three (3) months after the
termination of the Optionholder's Continuous Service during which the exercise
of the Option would not be in violation of such registration requirements.
 
      (J) DISABILITY OF OPTIONHOLDER. In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the
Optionholder may exercise his
 
                                      12.
<PAGE>
or her Option (to the extent that the Optionholder was entitled to exercise such
Option as of 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, after termination of Continuous Service, the Optionholder does
not exercise his or her Option within the time specified herein or in the Option
Agreement (as applicable), the Option shall terminate.
 
      (K) DEATH OF OPTIONHOLDER. In the event that (i) an Optionholder's
Continuous Service terminates as a result of the Optionholder's death or (ii)
the Optionholder dies within the period (if any) specified in the Option
Agreement after the termination of the Optionholder's Continuous Service for a
reason other than death, then the Option may be exercised (to the extent the
Optionholder was entitled to exercise such Option as of the date of death) by
the Optionholder'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 Optionholder's death pursuant to Section 6(e) or 6(f), but only
within the period ending on the earlier of (1) the date eighteen (18) months
following the date of death (or such longer or shorter period specified in the
Option Agreement or (2) the expiration of the term of such Option as set forth
in the Option Agreement. If, after the Optionholder's death, the Option is not
exercised within the time specified herein or in the Option Agreement (as
applicable), the Option shall terminate.
 
      (L) RETIREMENT. Notwithstanding the foregoing, if at the time of
termination of an Optionholder's Continuous Service for any reason other than
Cause, the Optionholder is at least fifty five (55) years old, then the
Optionholder (or such person or person(s) as may be entitled to exercise such
Option pursuant to Section 6(k) in the event of the Optionholder's death) may
exercise his or her Option (to the extent that the Optionholder was entitled to
exercise such Option as of the date of termination) within such period of time
ending on the earlier of (i) the date twenty four (24) months following such
termination or (ii) the expiration of the term of the Option as set forth in the
Option Agreement. If, after termination, the Option is not exercised within the
time specified herein, the Option shall terminate.
 
      (M) TERMINATION FOR CAUSE. In the event an Optionholder's Continuous
Service is terminated for Cause, the Option shall terminate upon the termination
date of such Optionholder's Continuous Service and the Optionholder shall be
prohibited from exercising his or her Option from and after the time of such
termination of Continuous Service.
 
      (N) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionholder may elect at any time before the Optionholder's
Continuous Service terminates to exercise the Option as to any part or all of
the shares of Common Stock subject to the Option prior to the full vesting of
the Option. Any unvested shares of Common Stock so purchased may be subject to a
repurchase option in favor of the Company or to any other restriction the Board
determines to be appropriate. The Company shall not be required to exercise its
repurchase option until at least six (6) months (or such longer or shorter
period of time required to avoid a charge to earnings for financial accounting
purposes) have elapsed following exercise of the Option unless the Board
otherwise specifically provides in the Option.

7. PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.
 
      (A) RESTRICTED STOCK AWARDS. Each Restricted Stock Award Agreement shall
be in such form and shall contain such terms and conditions as the Board shall
deem appropriate. At the Board's election, shares of Common Stock may be (i)
held in book entry form subject to the Company's instructions until any
restrictions relating to the Restricted Stock Award lapse; or (ii) evidenced by
a certificate, which certificate shall be held in such form and manner as
determined by the Board. The terms and conditions of Restricted Stock Award
Agreements may change from time to time, and the terms and conditions of
separate Restricted Stock Award Agreements need not be identical, provided,
however, that each Restricted Stock Award Agreement shall include (through
incorporation of the provisions hereof by reference in the agreement or
otherwise) the substance of each of the following provisions:
 
            (I) PURCHASE PRICE. At the time of the grant of a Restricted Stock
Award, the Board will determine the price to be paid by the Participant for each
share subject to the Restricted Stock Award. To the extent required by
applicable law, the price to be paid by the Participant for each share of the
Restricted Stock Award will not be less than the par value of a share of Common
Stock. A Restricted Stock Award may be awarded as a stock bonus (i.e., with no
cash purchase price to be paid) to the extent permissible under applicable law.
 
            (II) CONSIDERATION. At the time of the grant of a Restricted Stock
Award, the Board will determine the consideration permissible for the payment of
the purchase price of the Restricted Stock Award. The purchase price of Common
Stock acquired pursuant to the Restricted Stock Award shall be paid in one of
the following ways: (i) in cash at the time of purchase; (ii) at the discretion
of the Board, according to a deferred payment or other similar arrangement with
the Participant; (iii) by services previously rendered to the Company in the
case of a stock bonus; or (iv) in any other form of legal consideration that may
be acceptable to the Board and permissible under the Delaware Corporation Law.
 
            (III) VESTING. Shares of Common Stock acquired under a Restricted
Stock Award may, but need not, be (i) subject to a share repurchase right or
option in favor of the Company or (ii) subject to a forfeiture right in favor of
the Company, each in accordance with a vesting schedule to be determined by the
Board.
 
            (IV) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. In the event
that a Participant's Continuous Service terminates, the Company shall have the
right, but not the obligation, to repurchase, otherwise reacquire or receive by
a forfeiture right, any or all of the shares of Common Stock held by the
Participant that have not vested as of the date of termination under the terms
of the Restricted Stock Award Agreement. At the Board's election, the repurchase
right may be at the least of: (i) the Fair Market Value on the relevant date;
(ii) the Participant's original cost; or (iii) if the Participant paid the
purchase price for the shares of Common Stock with services rendered, then for
no consideration. The Company shall not be required to exercise its repurchase
option until at least six (6) months (or such longer or shorter period of time
required to avoid a charge to earnings for financial accounting purposes) have
elapsed following the purchase of the restricted stock unless otherwise
determined by the Board or provided in the Restricted Stock Award Agreement.
 
                                      14.
<PAGE>
            (V) TRANSFERABILITY. Rights to purchase or receive shares of Common
Stock granted under a Restricted Stock Award shall be transferable by the
Participant only upon such terms and conditions as are set forth in the
Restricted Stock Award Agreement, as the Board shall determine in its
discretion, and so long as Common Stock awarded under the Restricted Stock Award
remains subject to the terms of the Restricted Stock Award Agreement.
 
      (B) PHANTOM STOCK. Each Phantom Stock Award Agreement shall be in such
form and shall contain such terms and conditions as the Board shall deem
appropriate. The terms and conditions of Phantom Stock Award Agreements may
change from time to time, and the terms and conditions of separate Phantom Stock
Award Agreements need not be identical, provided, however, that each Phantom
Stock Award Agreement shall include (through incorporation of the provisions
hereof by reference in the agreement or otherwise) the substance of each of the
following provisions:
 
            (I) CONSIDERATION. At the time of grant of a Phantom Stock Award,
the Board will determine the consideration, if any, to be paid by the
Participant upon delivery of each share of Common Stock subject to the Phantom
Stock Award. To the extent required by applicable law, the consideration to be
paid by the Participant for each share of Common Stock subject to a Phantom
Stock Award will not be less than the par value of a share of Common Stock. Such
consideration may be paid in any form permitted under applicable law.
 
            (II) VESTING. At the time of the grant of a Phantom Stock Award, the
Board may impose such restrictions or conditions to the vesting of the Phantom
Stock Award as it, in its absolute discretion, deems appropriate.
 
            (III) PAYMENT. A Phantom Stock Award may be settled by the delivery
of shares of Common Stock, their cash equivalent, any combination thereof or in
any other form of consideration as determined by the Board and contained in the
Phantom Stock Award Agreement.
 
            (IV) ADDITIONAL RESTRICTIONS. At the time of the grant of a Phantom
Stock Award, the Board, as it deems appropriate, may impose such restrictions or
conditions that delay the delivery of the shares of Common Stock (or their cash
equivalent) subject to a Phantom Stock Award after the vesting of such Phantom
Stock Award.
 
            (V) DIVIDEND EQUIVALENTS. Dividend equivalents may be credited in
respect of shares of Common Stock covered by a Phantom Stock Award, as
determined by the Board and contained in the Phantom Stock Award Agreement. At
the discretion of the Board, such dividend equivalents may be converted into
additional shares of Common Stock covered by the Phantom Stock Award in such
manner as determined by the Board. Any additional shares covered by the Phantom
Stock Award credited by reason of such dividend equivalents will be subject to
all the terms and conditions of the underlying Phantom Stock Award Agreement to
which they relate.
 
            (VI) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. Except as
otherwise provided in the applicable Phantom Stock Award Agreement, such portion
of the Phantom Stock
 
                                      15.
<PAGE>
Award that has not vested will be forfeited upon the Participant's termination
of Continuous Service for any reason.
 
      (C) STOCK APPRECIATION RIGHTS. Each Stock Appreciation Right 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 Appreciation Right
Agreements may change from time to time, and the terms and conditions of
separate Stock Appreciation Right Agreements need not be identical, provided,
however, that each Stock Appreciation Right Agreement shall include (through
incorporation of the provisions hereof by reference in the agreement or
otherwise) the substance of each of the following provisions:
 
            (I) STRIKE PRICE AND CALCULATION OF APPRECIATION. Each Stock
Appreciation Right will be denominated in share of Common Stock equivalents. The
appreciation distribution payable on the exercise of a Stock Appreciation Right
will 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 Stock Appreciation Right) of a
number of shares of Common Stock equal to the number of share of Common Stock
equivalents in which the Participant is vested under such Stock Appreciation
Right, and with respect to which the Participant is exercising the Stock
Appreciation Right on such date, over (B) an amount (the strike price) that will
be determined by the Board at the time of grant of the Stock Appreciation Right.
 
            (II) VESTING. At the time of the grant of a Stock Appreciation
Right, the Board may impose such restrictions or conditions to the vesting of
such Stock Appreciation Right as it, in its absolute discretion, deems
appropriate.
 
            (III) EXERCISE. To exercise any outstanding Stock Appreciation
Right, the Participant must provide written notice of exercise to the Company in
compliance with the provisions of the Stock Appreciation Right Agreement
evidencing such Stock Appreciation Right.
 
            (IV) PAYMENT. The appreciation distribution in respect to a Stock
Appreciation Right may be paid in Common Stock, in cash, in any combination
thereof or in any other form of consideration as determined by the Board and
contained in the Stock Appreciation Right Agreement evidencing such Stock
Appreciation Right.
 
            (V) TERMINATION OF CONTINUOUS SERVICE. In the event that a
Participant's Continuous Service terminates, the Participant may exercise his or
her Stock Appreciation Right (to the extent that the Participant was entitled to
exercise such Stock Appreciation Right as of the date of termination) but only
within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Participant's Continuous Service (or
such longer or shorter period specified in the Stock Appreciation Right
Agreement) or (ii) the expiration of the term of the Stock Appreciation Right as
set forth in the Stock Appreciation Right Agreement. If, after termination, the
Participant does not exercise his or her Stock Appreciation Right within the
time specified herein or in the Stock Appreciation Right Agreement (as
applicable), the Stock Appreciation Right shall terminate.
 
                                      16.
<PAGE>
      (D) OTHER STOCK AWARDS. Other forms of Stock Awards valued in whole or in
part by reference to, or otherwise based on, Common Stock may be granted either
alone or in addition to Stock Awards provided for under Section 6 and the
preceding provisions of this Section 7. Subject to the provisions of the Plan,
the Board shall have sole and complete authority to determine the persons to
whom and the time or times at which such Other Stock Awards will be granted, the
number of shares of Common Stock (or the cash equivalent thereof) to be granted
pursuant to such Other Stock Awards and all other terms and conditions of such
Other Stock Awards.
 
8. COVENANTS OF THE COMPANY.
 
      (A) AVAILABILITY OF SHARES. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.
 
      (B) SECURITIES LAW COMPLIANCE. 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 Common 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 Common Stock
under the Plan, the Company shall be relieved from any liability for failure to
issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained.
 
9. USE OF PROCEEDS FROM STOCK.
 
      Proceeds from the sale of Common Stock pursuant to Stock Awards shall
constitute general funds of the Company.
 
10. MISCELLANEOUS.
 
      (A) ACCELERATION OF EXERCISABILITY AND VESTING. 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 in accordance
with the Plan, 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) STOCKHOLDER RIGHTS. No Participant shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.
 
      (C) NO EMPLOYMENT OR OTHER SERVICE RIGHTS. Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the
 
                                      17.
<PAGE>
employment of an Employee with or without notice and with or without cause, (ii)
the service of a Consultant pursuant to the terms of such Consultant's agreement
with the Company or an Affiliate or (iii) the service of a Director pursuant to
the Bylaws of the Company or an Affiliate, and any applicable provisions of the
corporate law of the state in which the Company or the Affiliate is
incorporated, as the case may be.
 
      (D) INCENTIVE STOCK OPTION $100,000 LIMITATION. To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which Incentive Stock Options are exercisable for the first time
by any Optionholder 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 that exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options, notwithstanding
any contrary provision of the applicable Option Agreement(s).
 
      (E) INVESTMENT ASSURANCES. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to
give written assurances satisfactory to the Company as to the Participant'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 (ii) to
give written assurances satisfactory to the Company stating that the Participant
is acquiring Common Stock subject to the Stock Award for the Participant's own
account and not with any present intention of selling or otherwise distributing
the Common Stock. The foregoing requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (1) the issuance of the shares of
Common Stock upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration
statement under the Securities Act or (2) 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 Common Stock.
 
      (F) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of a
Stock Award Agreement, the Company may in its sole discretion, satisfy any
federal, state or local tax withholding obligation relating to a Stock Award by
any of the following means (in addition to the Company's right to withhold from
any compensation paid to the Participant by the Company) or by a combination of
such means: (i) causing the Participant to tender a cash payment; (ii)
withholding shares of Common Stock from the shares of Common Stock issued or
otherwise issuable to the Participant in connection with the Stock Award; or
(iii) by such other method as may be set forth in the Stock Award Agreement.
 
11. ADJUSTMENTS UPON CHANGES IN STOCK.
 
      (A) CAPITALIZATION ADJUSTMENTS. If any change is made in, or other event
occurs with respect to, the Common Stock subject to the Plan or subject to any
Stock Award without the
 
                                      18.
<PAGE>
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 (each a
"CAPITALIZATION ADJUSTMENT"), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject to the Plan pursuant to
Sections 4(a) and 4(b) and the maximum number of securities subject to award to
any person pursuant to Section 5(c), and the outstanding Stock Awards will be
appropriately adjusted in the class(es) and number of securities and price per
share of Common Stock subject to such outstanding Stock Awards. The Board shall
make such adjustments, and its determination shall be final, binding and
conclusive. (Notwithstanding the foregoing, the conversion of any convertible
securities of the Company shall not be treated as a transaction "without receipt
of consideration" by the Company.)
 
      (B) DISSOLUTION OR LIQUIDATION. In the event of a dissolution or
liquidation of the Company, then all outstanding Stock Awards shall terminate
immediately prior to the completion of such dissolution or liquidation.
 
      (C) CORPORATE TRANSACTION. In the event of a Corporate Transaction, any
surviving corporation or acquiring corporation may assume or continue any or all
Stock Awards outstanding under the Plan or may substitute similar stock awards
for Stock Awards outstanding under the Plan (including, but not limited to,
awards to acquire the same consideration paid to the stockholders of the
Company, as the case may be, pursuant to the Corporate Transaction), and any
reacquisition or repurchase rights held by the Company in respect of Common
Stock issued pursuant to Stock Awards may be assigned by the Company to the
successor of the Company (or the successor's parent company), if any, in
connection with such Corporate Transaction. In the event that any surviving
corporation or acquiring corporation does not assume or continue all such
outstanding Stock Awards or substitute similar stock awards for all such
outstanding Stock Awards, then with respect to Stock Awards that have been not
assumed, continued or substituted and that are held by Participants whose
Continuous Service has not terminated prior to the effective time of the
Corporate Transaction, the vesting of such Stock Awards (and, if applicable, the
time at which such Stock Awards may be exercised) shall (contingent upon the
effectiveness of the Corporate Transaction) be accelerated in full to a date
prior to the effective time of such Corporate Transaction as the Board shall
determine (or, if the Board shall not determine such a date, to the date that is
five (5) days prior to the effective time of the Corporate Transaction), and
such Stock Awards shall terminate if not exercised (if applicable) at or prior
to such effective time, and any reacquisition or repurchase rights held by the
Company with respect to such Stock Awards shall (contingent upon the
effectiveness of the Corporate Transaction) lapse. With respect to any other
Stock Awards outstanding under the Plan that have not been assumed, continued or
substituted, the vesting of such Stock Awards (and, if applicable, the time at
which such Stock Award may be exercised) shall not be accelerated, unless
otherwise provided in a written agreement between the Company or any Affiliate
and the holder of such Stock Award, and such Stock Awards shall terminate if not
exercised (if applicable) prior to the effective time of the Corporate
Transaction.
 
      (D) CHANGE IN CONTROL. A Stock Award may be subject to additional
acceleration of vesting and exercisability upon or after a Change in Control as
may be provided in the Stock Award Agreement for such Stock Award or as may be
provided in any other written agreement
 
                                      19.
<PAGE>
between the Company or any Affiliate and the Participant, but in the absence of
such provision, no such acceleration shall occur.
 
12. AMENDMENT OF THE PLAN AND STOCK AWARDS.
 
      (A) AMENDMENT OF PLAN. Subject to the limitations, if any, of applicable
law, the Board at any time, and from time to time, may amend the Plan. However,
except as provided in Section 11(a) relating to Capitalization Adjustments, no
amendment shall be effective unless approved by the stockholders of the Company
to the extent stockholder approval is necessary to satisfy applicable law.
 
      (B) STOCKHOLDER APPROVAL. The Board, in its sole discretion, may 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 Covered Employees.
 
      (C) CONTEMPLATED AMENDMENTS. It is expressly contemplated that the Board
may amend the Plan in any respect the Board deems necessary or advisable to
provide eligible Employees 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) NO IMPAIRMENT OF RIGHTS. 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 Participant and (ii) the Participant
consents in writing.
 
      (E) AMENDMENT OF STOCK AWARDS. The Board at any time, and from time to
time, may amend the terms of any one or more Stock Awards, including, but not
limited to, amendments to provide terms more favorable than previously provided
in the agreement evidencing a Stock Award, subject to any specified limits in
the Plan that are not subject to Board discretion; 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 Participant and (ii) the Participant
consents in writing.
 
13. TERMINATION OR SUSPENSION OF THE PLAN.
 
      (A) PLAN TERM. 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) NO IMPAIRMENT OF RIGHTS. Suspension or termination of the Plan shall
not impair rights and obligations under any Stock Award granted while the Plan
is in effect except with the written consent of the Participant.
 
                                      20.
<PAGE>
14. EFFECTIVE DATE OF PLAN.
 
      The Plan shall become effective on the IPO Date, but no Stock Award 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.
