         Pursuant to the terms of the Plan, the Administrator shall have the
power and authority to grant to Eligible Recipients pursuant to the terms of the
Plan: (a) Stock Options, (b) Stock Appreciation Rights, (c) awards of Restricted
Stock, Deferred Stock or Performance Shares or (d) any combination of the
foregoing. In particular, the Administrator shall have the authority:

              (b) to determine whether and to what extent Stock Options, Stock
Appreciation Rights, awards of Restricted Stock, Deferred Stock or Performance

Participants;

              (c) to determine the number of shares of Stock to be covered by

the terms of the Plan, of each award granted hereunder (including, but not
limited to, (x) the restrictions applicable to awards of Restricted Stock or

Stock Options, Stock Appreciation Rights, awards of Restricted Stock, Deferred
Stock or Performance Shares or any combination of the foregoing granted

                                       3

<PAGE>


              (f) to reduce the option price of any Stock Option to the then
current Fair Market Value if the Fair Market Value of the Stock covered by such
Stock Option has declined since the date such Stock Option was granted.

         The Administrator shall have the authority, in its sole discretion, to
adopt, alter and repeal such administrative rules, guidelines and practices
governing the Plan as it shall from time to time deem advisable; to interpret
the terms and provisions of the Plan and any award issued under the Plan (and
any agreements relating thereto); and to otherwise supervise the administration
of the Plan.

         All decisions made by the Administrator pursuant to the provisions of
the Plan shall be final, conclusive and binding on all persons, including, but
not limited to the Company and the Participants.

SECTION 3.  STOCK SUBJECT TO PLAN.

         The total number of shares of Stock reserved and available for issuance
under the Plan shall be 4,181,500 shares. Such shares may consist, in whole or
in part, of authorized and unissued shares or treasury shares. To the extent
that (i) a Stock Option expires or is otherwise terminated without being
exercised, or (ii) any shares of Stock subject to any award of Restricted Stock,
Deferred Stock or Performance Shares granted hereunder are forfeited, such
shares of Stock shall again be available for issuance in connection with future
awards granted under the Plan. If any shares of Stock have been pledged as
collateral for indebtedness incurred by a Participant in connection with the
exercise of a Stock Option and such shares of Stock are returned to the Company
in satisfaction of such indebtedness, such shares of Stock shall again be
available for issuance in connection with future awards granted under the Plan.

         In the event of any merger, reorganization, consolidation,
recapitalization, stock dividend or other change in corporate structure
affecting the Stock, an equitable substitution or proportionate adjustment shall

under the Plan, (ii) the kind, number and option price of shares of Stock
subject to outstanding Stock Options granted under the Plan, and (iii) the kind,
number and purchase price of shares of Stock subject to outstanding awards of
Restricted Stock, Deferred Stock and Performance Shares granted under the Plan,
in each case as may be determined by the Administrator, in its sole discretion.
Such other substitutions or adjustments shall be made as may be determined by
the Administrator, in its sole discretion. An adjusted option price shall also
be used to determine the amount payable by the Company upon the exercise of any
Stock Appreciation Right related to any Stock Option. In connection with any
event described in this paragraph, the Administrator may provide, in its sole
discretion, for the cancellation of any outstanding awards and payment in cash
or other property therefor.

SECTION 4.  ELIGIBILITY.

         Eligible Recipients shall be eligible to be granted Stock Options,
Stock Appreciation Rights, awards of Restricted Stock, Deferred Stock or
Performance Shares or any combination of the foregoing hereunder. The
Participants under the Plan shall be selected from time to time by the
Administrator, in its sole discretion, from among the Eligible Recipients, and
the Administrator shall determine, in its sole discretion, the number of shares
of Stock covered by each such award.

SECTION 5.  STOCK OPTIONS.

         Stock Options may be granted alone or in addition to other awards
granted under the Plan. Any Stock Option granted under the Plan shall be in such
form as the Administrator may from time to time approve, and the provisions of
Stock Option awards need not be the same with respect to each Participant.
Participants who are granted Stock Options shall enter into a subscription
and/or award agreement with the Company, in such form as the Administrator shall
determine, which agreement shall set forth, among other things, the option price
of the Stock Option, the term of the Stock Option and provisions regarding
exercisability of the Stock Option granted thereunder.

         The Stock Options granted under the Plan are not intended to qualify as
"incentive stock options" within the meaning of Section 422 of the Code.

         The Administrator shall have the authority to grant to any officer or
employee of the Company or of any Parent or Subsidiary (including directors who
are also officers of the Company) Stock Options (with or without Stock
Appreciation Rights). More than one Stock Option may be granted to the same
Participant and be outstanding concurrently hereunder.

         Stock Options granted under the Plan shall be subject to the following
terms and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Administrator shall deem
desirable:

         (1) OPTION PRICE. The option price per share of Stock purchasable under
a Stock Option shall be determined by the Administrator in its sole discretion
at the time of grant but shall not be less than the par value of the Stock on
such date.

         (2) OPTION TERM. The term of each Stock Option shall be fixed by the
Administrator.

         (3) EXERCISABILITY. Stock Options shall be exercisable at such time or
times and subject to such terms and conditions as shall be determined by the
Administrator at or after the time of grant. The Administrator may provide at
the time of grant, in its sole discretion, that any Stock Option shall be
exercisable only in installments, and the Administrator may waive such
installment exercise provisions at any time, in whole or in part, based on such
factors as the Administrator may determine, in its sole discretion, including
but not limited to in connection with any change of control.

                                       5

<PAGE>


         (4) METHOD OF EXERCISE. Subject to paragraph (3) of this Section 5,
Stock Options may be exercised in whole or in part at any time during the option
period, by giving written notice of exercise to the Company specifying the
number of shares of Stock to be purchased, accompanied by payment in full of the
purchase price in cash or its equivalent, as determined by the Administrator. As
determined by the Administrator, in its sole discretion, payment in whole or in
part may also be made (i) by means of any cashless exercise procedure approved
by the Administrator, (ii) in the form of unrestricted Stock already owned by
the Participant which, (x) in the case of unrestricted Stock acquired upon
exercise of an option, have been owned by the Participant for more than six
months on the date of surrender, and (y) has a Fair Market Value on the date of
surrender equal to the aggregate option price of the Stock as to which such
Stock Option shall be exercised, or (iii) in the case of the exercise of a Stock
Option, in the form of Restricted Stock or Performance Shares subject to an
award hereunder (based, in each case, on the Fair Market Value of the Stock on
the date the Stock Option is exercised). If payment of the option price of a
Stock Option is made in whole or in part in the form of Restricted Stock or
Performance Shares, the shares of Stock received upon the exercise of such Stock
Option shall be restricted in accordance with the original terms of the
Restricted Stock award or Performance Shares award in question, except that the
Administrator may direct that such restrictions shall apply only to that number
of shares of Stock equal to the number of shares surrendered upon the exercise
of such Stock Option. A Participant shall generally have the rights to dividends
and any other rights of a stockholder with respect to the Stock subject to the
Stock Option only after the Participant has given written notice of exercise,
has paid in full for such shares, and, if requested, has given the
representation described in paragraph (2) of Section 10 below.

         The Administrator may require the surrender of all or a portion of any
Stock Option granted under the Plan as a condition precedent to the grant of a
new Stock Option. Subject to the provisions of the Plan, such new Stock Option
shall be exercisable at the price, during such period and on such other terms
and conditions as are specified by the Administrator at the time the new Stock
Option is granted. Upon their surrender, Stock Options shall be canceled and the
shares of Stock previously subject to such canceled Stock Options shall again be
available for future grants of Stock Options and other awards hereunder.

         (5) LOANS. The Company or any Parent or Subsidiary may make loans
available to Stock Option holders in connection with the exercise of outstanding
Stock Options, as the Administrator, in its sole discretion, may determine. Such
loans shall (i) be evidenced by promissory notes entered into by the Stock
Option holders in favor of the Company or any Parent or Subsidiary, (ii) be
subject to the terms and conditions set forth in this Section 5(5) and such
other terms and conditions, not inconsistent with the Plan, as the Administrator
shall determine, (iii) bear interest at the applicable Federal interest rate or
such other rate as the Administrator shall determine, and (iv) be subject to
Board approval (or to approval by the Administrator to the extent the Board may
delegate such authority). In no event may the principal amount of any such loan
exceed the sum of (x) the aggregate option price less the par value (if any) of
the shares of Stock covered

                                       6

<PAGE>

by the Stock Option, or portion thereof, exercised by the holder, and (y) any
Federal, state, and local income tax attributable to such exercise. The initial
term of the loan, the schedule of payments of principal and interest under the
loan, the extent to which the loan is to be with or without recourse against the
holder with respect to principal and/or interest and the conditions upon which
the loan will become payable in the event of the holder's termination of service
to the Company or to any Parent or Subsidiary shall be determined by the
Administrator. Unless the Administrator determines otherwise, when a loan is
made, shares of Stock having a Fair Market Value at least equal to the principal
amount of the loan shall be pledged by the holder to the Company as security for
payment of the unpaid balance of the loan, and such pledge shall be evidenced by
a pledge agreement, the terms of which shall be determined by the Administrator,
in its sole discretion; provided, however, that each loan shall comply with all
applicable laws, regulations and rules of the Board of Governors of the Federal
Reserve System and any other governmental agency having jurisdiction.

         (6) NON-TRANSFERABILITY OF STOCK OPTIONS. Except under the laws of
descent and distribution, unless otherwise determined by the Administrator, the
optionee shall not be permitted to sell, transfer, pledge or assign any Stock
Option, and all Stock Options shall be exercisable, during the optionee's
lifetime, only by the optionee; provided, however, that the optionee shall be
permitted to transfer one or more Stock Options to a trust controlled by the
optionee during the optionee's lifetime for estate planning purposes.


         (7) TERMINATION OF EMPLOYMENT OR SERVICE. If a Participant's employment
with or service as a director, consultant or advisor to the Company or to any
Parent or Subsidiary terminates by reason of his or her death, Disability or for
any other reason, the Stock Option may thereafter be exercised to the extent
provided in the agreement evidencing such Stock Option, or as otherwise
determined by the Administrator following termination of employment.

SECTION 6.  STOCK APPRECIATION RIGHTS.

         Stock Appreciation Rights may be granted either alone ("Free Standing
Rights") or in conjunction with all or part of any Stock Option granted under
the Plan ("Related Rights"). Related Rights may be granted either at or after
the time of the grant of the Stock Option. The Administrator shall determine the
Eligible Recipients to whom, and the time or times at which, grants of Stock
Appreciation Rights shall be made; the number of shares of Stock to be awarded,
the exercise price, and all other conditions of Stock Appreciation Rights. The
provisions of Stock Appreciation Rights need not be the same with respect to
each Participant.

         Stock Appreciation Rights granted under the Plan shall be subject to
the following terms and conditions and shall contain such additional terms and
conditions, not inconsistent with the terms of the Plan, as the Administrator
shall deem desirable:

         (1) AWARDS. The prospective recipient of a Stock Appreciation Right
shall not have any rights with respect to such award, unless and until such
recipient has executed an agreement evidencing the award (a "Stock Appreciation
Right Agreement") and delivered a fully executed copy thereof to the Company,
within a period of sixty days (or such other period as the Administrator may
specify) after the award date. Participants who are granted Stock Appreciation
Rights shall have no rights as stockholders of the Company with respect to the
grant or exercise of such rights.

         (2) EXERCISABILITY.

              (a) Stock Appreciation Rights that are Free Standing Rights ("Free

Administrator at or after grant; provided, however, that no Free Standing Stock
Appreciation Right shall be exercisable during the first six months of its term,
except that this additional limitation shall not apply in the event of a
Participant's death or Disability prior to the expiration of such six-month
period.

              (b) Stock Appreciation Rights that are Related Rights ("Related
Stock Appreciation Rights") shall be exercisable only at such time or times and
to the extent that the Stock Options to which they relate shall be exercisable
in accordance with the provisions of Section 5 above and this Section 6 of the
Plan; provided, however, that no Related Stock Appreciation Right shall be
exercisable during the first six months of its term, except that this additional
limitation shall not apply in the event of a Participant's death or Disability
prior to the expiration of such six-month period.

         (3) PAYMENT UPON EXERCISE.

              (a) Upon the exercise of a Free Standing Stock Appreciation Right,
the Participant shall be entitled to receive up to, but not more than, an amount
in cash or that number of shares of Stock (or any combination of cash and shares
of Stock) equal in value to the excess of the Fair Market Value of one share of
Stock as of the date of exercise over the price per share specified in the Free
Standing Stock Appreciation Right (which price shall be no less than 100% of the
Fair Market Value of the Stock on the date of grant) multiplied by the number of
shares of Stock in respect of which the Free Standing Stock Appreciation Right
is being exercised, with the Administrator having the right to determine the
form of payment.

              (b) A Related Right may be exercised by a Participant by
surrendering the applicable portion of the related Stock Option. Upon such
exercise and surrender, the Participant shall be entitled to receive up to, but
not more than, an amount in cash or that number of shares of Stock (or any
combination of cash and shares of Stock) equal in value to the excess of the
Fair Market Value of one share of Stock as of the date of exercise over the
option price per share specified in the related Stock Option multiplied by the
number of shares of Stock in respect of which the Related Stock Appreciation
Right is being exercised, with the Administrator having the right to

                                       8

<PAGE>

determine the form of payment. Stock Options which have been so surrendered, in
whole or in part, shall no longer be exercisable to the extent the Related
Rights have been so exercised.

         (4) NON-TRANSFERABILITY.

              (a) Free Standing Stock Appreciation Rights shall be transferable
only when and to the extent that a Stock Option would be transferable under
paragraph (6) of Section 5 of the Plan.

              (b) Related Stock Appreciation Rights shall be transferable only
when and to the extent that the underlying Stock Option would be transferable
under paragraph (6) of Section 5 of the Plan.

         (5) TERMINATION OF EMPLOYMENT OR SERVICE.

              (a) In the event of the termination of employment or service of a
Participant who has been granted one or more Free Standing Stock Appreciation
Rights, such rights shall be exercisable at such time or times and subject to
such terms and conditions as shall be determined by the Administrator at or
after grant.

              (b) In the event of the termination of employment or service of a
Participant who has been granted one or more Related Stock Appreciation Rights,
such rights shall be exercisable at such time or times and subject to such terms
and conditions as set forth in the related Stock Options.

         (6) TERM.

              (a) The term of each Free Standing Stock Appreciation Right shall
be fixed by the Administrator, but no Free Standing Stock Appreciation Right
shall be exercisable more than ten years after the date such right is granted.

              (b) The term of each Related Stock Appreciation Right shall be the
term of the Stock Option to which it relates, but no Related Stock Appreciation
Right shall be exercisable more than ten years after the date such right is
granted.

SECTION 7.  RESTRICTED STOCK, DEFERRED STOCK AND PERFORMANCE SHARES.

              Awards of Restricted Stock, Deferred Stock or Performance Shares
may be issued either alone or in addition to other awards granted under the
Plan. The Administrator shall determine the Eligible Recipients to whom, and the
time or times at which, awards of Restricted Stock, Deferred Stock or
Performance Shares shall be made; the number of shares to be awarded; the price,
if any, to be paid by the Participant for the acquisition of Restricted Stock,
Deferred Stock or Performance Shares; the Restricted Period (as defined in
paragraph (2) of this Section 7) applicable to awards of Restricted Stock or
Deferred Stock; the performance objectives applicable to awards of Deferred

                                       9

<PAGE>

Stock or Performance Shares; and all other conditions of the awards of
Restricted Stock, Deferred Stock and Performance Shares. The Administrator may
also condition the grant of the award of Restricted Stock, Deferred Stock or
Performance Shares upon the exercise of Stock Options, or upon such other
criteria as the Administrator may determine, in its sole discretion. The
provisions of the awards of Restricted Stock, Deferred Stock or Performance
Shares need not be the same with respect to each Participant. In the sole
discretion of the Administrator, loans may be made to Participants in connection
with the purchase of Restricted Stock under substantially the same terms and
conditions as provided in paragraph (5) of Section 5 of the Plan with respect to
the exercise of Stock Options.

              (1) AWARDS AND CERTIFICATES. The prospective recipient of awards
of Restricted Stock, Deferred Stock or Performance Shares shall not have any
rights with respect to any such award, unless and until such recipient has
executed an agreement evidencing the award (a "Restricted Stock Award
Agreement," "Deferred Stock Award Agreement" or "Performance Shares Award
Agreement," as appropriate) and delivered a fully executed copy thereof to the
Company, within a period of sixty days (or such other period as the
Administrator may specify) after the award date. Except as otherwise provided
below in this Section 7(2), (i) each Participant who is granted an award of
Restricted Stock or Performance Shares shall be issued a stock certificate in
respect of such shares of Restricted Stock or Performance Shares; and (ii) such
certificate shall be registered in the name of the Participant, and shall bear
an appropriate legend referring to the terms, conditions, and restrictions
applicable to any such award.

         The Company may require that the stock certificates evidencing
Restricted Stock or Performance Shares granted hereunder be held in the custody
of the Company until the restrictions thereon shall have lapsed, and that, as a
condition of any award of Restricted Stock or Performance Shares, the
Participant shall have delivered a stock power, endorsed in blank, relating to
the Stock covered by such award.

         With respect to awards of Deferred Stock, at the expiration of the
Restricted Period, stock certificates in respect of such shares of Deferred
Stock shall be delivered to the Participant, or his legal representative, in a
number equal to the number of shares of Stock covered by the Deferred Stock
award.

         (2) RESTRICTIONS AND CONDITIONS. The awards of Restricted Stock,
Deferred Stock and Performance Shares granted pursuant to this Section 7 shall
be subject to the following restrictions and conditions:

              (a) Subject to the provisions of the Plan and the Restricted Stock
Award Agreement, Deferred Stock Award Agreement or Performance Shares Award
Agreement, as appropriate, governing any such award, during such period as may
be set by the Administrator commencing on the date of grant (the "Restricted
Period"), the Participant shall not be permitted to sell, transfer, pledge or
assign shares of Restricted Stock, Deferred Stock or Performance Shares awarded
under the Plan; provided, however, that the Administrator may, in its sole
discretion, provide for the lapse of such

                                      10

<PAGE>

restrictions in installments and may accelerate or waive such restrictions in
whole or in part based on such factors and such circumstances as the
Administrator may determine, in its sole discretion, including, but not limited
to, the attainment of certain performance related goals, the Participant's
termination of employment or service as a director, consultant or advisor to the
Company or any Parent or Subsidiary, the Participant's death or Disability. If
the performance goals and other restrictions are not attained, the participant
will forfeit his or her shares of restricted stock, deferred stock and/or
performance shares.

              (b) Except as provided in paragraph (2)(a) of this Section 7, the
Participant shall generally have the rights of a stockholder of the Company with
respect to Restricted Stock or Performance Shares during the Restricted Period.
The Participant shall generally not have the rights of a stockholder with
respect to Stock subject to awards of Deferred Stock during the Restricted
Period; provided, however, that dividends declared during the Restricted Period
with respect to the number of shares of Stock covered by Deferred Stock shall be
paid to the Participant. Certificates for shares of unrestricted Stock shall be
delivered to the Participant promptly after, and only after, the Restricted
Period shall expire without forfeiture in respect of such awards of Restricted
Stock, Deferred Stock or Performance Shares except as the Administrator, in its
sole discretion, shall otherwise determine.

              (c) The rights of Participants granted awards of Restricted Stock,
Deferred Stock or Performance Shares upon termination of employment or service
as a director, consultant or advisor to the Company or to any Parent or
Subsidiary terminates for any reason during the Restricted Period shall be set
forth in the Restricted Stock Award Agreement, Deferred Stock Award Agreement or
Performance Shares Award Agreement, as appropriate, governing such awards.

SECTION 8.  AMENDMENT AND TERMINATION.

         The Board may amend, alter or discontinue the Plan, but no amendment,
alteration, or discontinuation shall be made that would impair the rights of a
Participant under any award theretofore granted without such Participant's
consent.

         The Administrator may amend the terms of any award theretofore granted,
prospectively or retroactively, but, subject to Section 3 of Plan, no such
amendment shall impair the rights of any Participant without his or her consent.

SECTION 9.  UNFUNDED STATUS OF PLAN.

         The Plan is intended to constitute an "unfunded" plan for incentive
compensation. With respect to any payments not yet made to a Participant by the
Company, nothing contained herein shall give any such Participant any rights
that are greater than those of a general creditor of the Company.

SECTION 10.  GENERAL PROVISIONS.

         (1) Shares of Stock shall not be issued pursuant to the exercise of any
award granted hereunder unless the exercise of such award and the issuance and
delivery of such shares of Stock pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act and the requirements of any stock exchange upon which
the Stock may then be listed, and shall be further subject to the approval of
counsel for the Company with respect to such compliance.

         (2) The Administrator may require each person acquiring shares of Stock
hereunder to represent to and agree with the Company in writing that such person
is acquiring the shares of Stock without a view to distribution thereof. The
certificates for such shares of Stock may include any legend which the
Administrator deems appropriate to reflect any restrictions on transfer.

         All certificates for shares of Stock delivered under the Plan shall be
subject to such stock-transfer orders and other restrictions as the
Administrator may deem advisable under the rules, regulations, and other
requirements of the Securities and Exchange Commission, any stock exchange upon
which the Stock is then listed, and any applicable Federal or state securities
law, and the Administrator may cause a legend or legends to be placed on any
such certificates to make appropriate reference to such restrictions.

         (3) Nothing contained in the Plan shall prevent the Board from adopting
other or additional compensation arrangements, subject to stockholder approval,
if such approval is required; and such arrangements may be either generally
applicable or applicable only in specific cases. The adoption of the Plan shall
not confer upon any Eligible Recipient any right to continued employment or
service with the Company or any Parent or Subsidiary, as the case may be, nor
shall it interfere in any way with the right of the Company or any Parent or
Subsidiary to terminate the employment or service of any of its Eligible
Recipients at any time.

         (4) Each Participant shall, no later than the date as of which the
value of an award first becomes includible in the gross income of the
Participant for Federal income tax purposes, pay to the Company, or make
arrangements satisfactory to the Administrator regarding payment of, any
Federal, state, or local taxes of any kind required by law to be withheld with
respect to such award. The obligations of the Company under the Plan shall be
conditional on the making of such payments or arrangements, and the Company
shall, to the extent permitted by law, have the right to deduct any such taxes
from any payment of any kind otherwise due to the Participant.

         (5) No member of the Board or the Administrator, nor any officer or
employee of the Company acting on behalf of the Board or the Administrator,
shall be personally liable for any action, determination, or interpretation
taken or made in good faith with respect to the Plan, and all members of the
Board or the Administrator and each and any officer or employee of the Company
acting on their behalf shall, to the

                                      12

extent permitted by law, be fully indemnified and protected by the Company in
respect of any such action, determination or interpretation.

SECTION 11.  TERM OF PLAN.

         No Stock Option, Stock Appreciation Right, or award of Restricted
Stock, Deferred Stock or Performance Shares shall be granted pursuant to the
Plan on or after the tenth anniversary of the Effective Date, but awards
theretofore granted may extend beyond that date.
