            4. Administration of Plan.

            (a) Procedure. This Plan shall be administered by the Committee
appointed pursuant to this Section 4(a). The Committee shall consist of two or
more Outside Directors appointed by the Board, but all Committee members must be
Disinterested Persons. If the Board fails to appoint such persons, the Committee
shall consist of all Outside Directors who are Disinterested Persons.

            (b) Powers of Committee. Subject to Section 5(b) below and otherwise
subject to the provisions of this Plan, the Committee shall have full and final
authority in its discretion to: (i) grant Incentive Stock Options and
Nonstatutory Stock Options, (ii) determine, upon review of relevant information
and in accordance with Section 7 below, the Fair Market Value of the Common
Stock; (iii) determine the exercise price per share of Options to be granted, in
accordance with this Plan, (iv) determine the Employees and Consultants to whom,
and the time or times at which, Options shall be granted, and the number of
shares to be represented by each Option; (v) cancel, with the consent of the
Optionee, outstanding Options and grant new Options in substitution therefor;
(vi) interpret this Plan; (vii) accelerate or defer (with the consent of
Optionee) the exercise date of any Option; (viii) prescribe, amend and rescind
rules


                                       -3-
<PAGE>

and regulations relating to this Plan; (ix) determine the terns and provisions
of each Option Granted (which need not be identical) by which Options shall be
evidenced and, with the consent of the holder thereof, modify or amend any
provisions (including without limitation provisions relating to the exercise
price and the obligation of any Optionee to sell purchased Shares to the Company
upon specified terms and conditions) of any Option; (x) require withholding from
or payment by an Optionee of any federal, state or local taxes; (xi) appoint and
compensate agents, counsel, auditors or other specialists as the Committee deems
necessary or advisable; (xii) correct any defect or supply any omission or
reconcile any inconsistency in this Plan and any agreement relating to any
Option, in such manner and to such extent the Committee determines to carry out
the purposes of this Plan, and; (xiii) construe and interpret this Plan, any
agreement relating to any Option, and make all other determinations deemed by
the Committee to be necessary or advisable for the administration of this Plan.

            A majority of the Committee shall constitute a quorum at any
meeting, and the acts of a majority of the members present, or acts unanimously
approved in writing by the entire Committee without a meeting, shall be the acts
of the Committee. A member of the Committee shall not participate in any
decisions with respect to himself under this Plan.

            (c) Effect of Committee's Decision. All decisions, determinations
and interpretations of the Committee shall be final and binding on all Optionees
and any other holders of any Options Granted under this Plan.

            5. Eligibility.

            (a) Options may be granted to any Employee, Consultant or Outside
Director as the Committee may from time to time designate, provided that (1)
Incentive Stock Options may be granted only to Employees, and (ii) Options may
be granted to Outside Directors only in accordance with the provisions of
Section 5(b) below. In selecting the individuals to whom Options shall be
granted, as well as in determining the number of Options Granted, the Committee
shall take into consideration such factors as it deems relevant in connection
with accomplishing the purpose of this Plan. Subject to the provisions of
Section 3 above, an Optionee may, if he or she is otherwise eligible, be granted
an additional Option or Options if the Committee shall so determine.

            (b) All grants of Options to Outside Directors under this Plan shall
be automatic and non-discretionary and shall be made strictly in accordance with
the following provisions:

            (i) No person shall have any discretion to select which Outside
Directors shall be granted options or to determine the number of Shares to be
covered by options granted to Outside Directors;


                                       -4-
<PAGE>

provided, that nothing in this Plan shall be construed to prevent an Outside
Director from declining to receive an Option under this Plan.

            (ii) The terns of each Option granted pursuant to this Section 5(b)
shall be as follows:

                        (A) the term of the option shall be ten (10) years;

                        (B) the Option shall become exercisable cumulatively
                        with respect to one-third of the Shares on each of the
                        first, second and third anniversaries of the date of
                        grant; provided, however, that in no event shall any
                        option be exercisable prior to obtaining stockholder
                        approval of this Plan; and

                        (C) the exercise price per share of Common Stock shall
                        be 100 % of the "Fair Market Value" (as defined in
                        Section 7(b) below) on the date of grant of the Option.

            (c) Each Option granted pursuant to Section 5(b) above shall be a
Nonstatutory Stock Option. Each other Option shall be designated in the written
option agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. Notwithstanding such designations, if and to the extent that the
aggregate Fair Market Value of the Shares with respect to which Options
designated as Incentive Stock Options are exercisable for the first time by any
Optionee during any calendar year (under all plans of the Company) exceeds
$100,000, such options shall be treated as Nonstatutory Stock Options. For
purposes of this Section 5(c), options shall be taken into account in the order
in which they are granted, and the Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (d) This Plan shall not confer upon any Optionee any right with
respect to continuation of employment by or the rendition of services to the
Company or any Parent or Subsidiary, nor shall it interfere in any way with his
or her right or the right of the Company or any Parent or Subsidiary to
terminate his or her employment or services at any time, with or without cause.
The terms of this Plan or any Options granted hereunder shall not be construed
to give any Optionee the right to any benefits not specifically provided by this
Plan or in any manner modify the Company's right to modify, amend or terminate
any of its pension or retirement plans.

            6. Term of Plan. This Plan shall become effective upon its adoption
by the Board of Directors of the Company subject to the approval thereof by vote
of the holders of a majority of the outstanding shares of the Company present,
or represented, and entitled to vote at a meeting to be duly held in accordance
with the applicable laws of the State of Delaware. Such meeting shall be held
within twelve months of the adoption of the plan by the Board of Directors. The
plan shall terminate


                                       -5-
<PAGE>

no later than January 1, 2006. No grants shall be made under this Plan after the
date of termination of this Plan. Any termination, either partially or wholly,
shall not affect any Options then outstanding under this Plan.

            7. Exercise Price and Consideration.

            (a) Exercise Price. The per Share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the Committee
as follows:

            (i) In the case of an Incentive Stock Option granted to any
Employee, the per Share exercise price shall be no less than 100 % of the Fair
Market Value per Share on the date of grant, but if granted to an Employee who,
at the time of the grant of such Incentive Stock Option, owns stock representing
more than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the per Share exercise price shall be no
less than 110 % of the Fair Market Value per Share on the date of grant.

            (ii) With respect to (i) above, the per Share exercise price is
subject to adjustment as provided in Section 10 below. For purposes of this
Section 7(a), if an Option is amended to reduce the exercise price, the date of
grant of such option shall thereafter be considered to be the date of such
amendment.

            (b) Fair Market Value. The "Fair Market Value" of the Common Stock
shall be determined by the Committee in its discretion; provided, that if the
Common Stock is listed on a stock exchange, the Fair Market Value per Share
shall be the closing price on such exchange on the date of grant of the Option
as reported in the Wall Street Journal (or, (i) if not so reported, as otherwise
reported by the exchange, and (ii) if not reported on the date of grant, then on
the last prior date on which a sale of the Common Stock was reported); or if not
listed on an exchange but traded on the National Association of Securities
Dealers Automated Quotation National Market System ("NASDAQ"), the Fair Market
Value per Share shall be the closing price per share of the Common Stock for the
date of grant, as reported in the Wall Street Journal (or, (i) if not so
reported, as otherwise reported by NASDAQ, and (ii) if not reported on the date
of grant, then on the last prior date on which a sale of the Common Stock was
reported); or, if the Common Stock is otherwise publicly traded, the mean of the
closing bid price and asked price for the last known sale.

            (c) Consideration. The consideration to be paid for the Shares to be
issued upon exercise of an Option, including the method of payment, shall be
determined by the Committee (and in the case of an Incentive Stock Option, shall
be determined at the time of grant) and may consist entirely of (i) cash; (ii)
check; (iii) the Optionee's personal interest bearing full recourse promissory
note with such terns and provisions as the Committee may authorize (provided
that no person who is not an Employee


                                       -6-
<PAGE>

of the Company may purchase Shares with a promissory note); (iv) other Shares of
Common Stock which (X) either have been owned by the Optionee for more than six
(6) months on the date of surrender or were not acquired directly or indirectly
from the Company, and (Y) have a Fair Market Value on the date of surrender
(determined without regard to any limitations on transferability imposed by
securities laws) equal to the aggregate exercise price of the Shares as to which
said Option shall be exercised; (v) any combination of such methods of payment;
or (vi) such other consideration and method of payment for the issuance of
Shares to the extent permitted under applicable laws.

            (d) Withholding. No later than the date as of which an amount first
becomes includable in the gross income of the Optionee for federal income tax
purposes with respect to an option, the Optionee shall pay to the Company (or
other entity identified by the Committee), or make arrangements satisfactory to
the Company or other entity identified by the Committee regarding the payment
of, any federal, state, local or foreign taxes of any kind required by law to be
withheld with respect to such amount required in order for the Company to obtain
a current deduction. Unless otherwise determined by the Committee, withholding
obligations may be settled with Common Stock, including Common Stock underlying
the subject option, provided that any applicable requirements under Section 16
of the Exchange Act are satisfied so as to avoid liability thereunder. The
obligations of the Company under this Plan shall be conditional upon such
payment or arrangements, and the Company shall, to the extent permitted by law,
have the right to deduct any such taxes from any payment otherwise due to the
Optionee.

            8. Options.

            (a) Term of Option. The term of each Option granted (other than an
Option granted under Section 5(b) above) shall be for a period of no more than
ten (10) years from the date of grant thereof or such shorter term as may be
provided in the Option agreement. However, in the case of an Option granted to
an Optionee who, at the time the Option is granted, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant thereof or such shorter time as may be provided in
the option Agreement.

            (b) Exercise of Options.

            (i) Procedure for Exercise; Rights as a Stockholder. Any option
granted under this Plan (other than an option granted pursuant to Section 5(b)
above) shall be exercisable at such times and under such conditions as
determined by the Committee, including performance criteria with respect to the
Company and/or the Optionee, and as shall otherwise be permissible under the
terms of this Plan.


                                       -7-
<PAGE>

            An Option may not be exercised for a fraction of a Share.

            An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Committee, consist of any
consideration and method of payment allowable under Section 7 of this Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a stockholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. If the
exercise of an Option is treated in part as the exercise of an Incentive Stock
Option and in part as the exercise of a Nonstatutory Stock Option pursuant to
Section 5(b) above, the Company shall issue a separate stock certificate
evidencing the Shares treated as acquired upon exercise of an Incentive Stock
Option and a separate stock certificate evidencing the Shares treated as
acquired upon exercise of a Nonstatutory Stock Option and shall identify each
such certificate accordingly in its stock transfer records. No adjustment will
be made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 10 of this
Plan.

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

            (ii) Method of Exercise. An Optionee may exercise an Option, in
whole or in part, at any time during the option period by the Optionee's giving
written notice of exercise on a form provided by the Committee (if available) to
the Company specifying the number of shares of Common Stock subject to the
Option to be purchased. Such notice shall be accompanied by payment in full of
the purchase price by cash or check or such other form of payment as the Company
may accept. If approved by the Committee, payment in full or in part may also be
made (A) by delivering Common Stock already owned by the Optionee having a total
Fair Market Value on the date of such delivery equal to the exercise price of
the subject Option; (B) by the execution and delivery of a note or other
evidence of indebtedness (and any security agreement thereunder) satisfactory to
the Committee; (C) by authorizing the Company to retain shares of Common Stock
which would otherwise be issuable upon exercise of the Option having a total
Fair Market Value on the date of delivery equal to the exercise price of the
subject Option; (D) by the delivery of cash by a broker-dealer to whom the
Optionee has submitted an irrevocable notice of exercise (in accordance with
Part 220, Chapter II, Title 12 of the Code of Federal Regulations, s0-called
"cashless" exercise); or (E) by any combination of the foregoing. In the case of
an Incentive Stock Option, the right to make a payment in the form of


                                       -8-
<PAGE>

already owned shares of Common Stock of the same class as the Common Stock
subject to the Option may be authorized only at the time the Option is granted.
No shares of Common Stock shall be issued until full payment therefor has been
made. An Optionee shall have all of the rights of a stockholder of the Company
holding the class of Common Stock that is subject to such Option (including, if
applicable, the right to vote the shares and the right to receive dividends),
when the Optionee has given written notice of exercise, has paid in full for
such shares and such shares have been recorded on the Company's official
stockholder records as having been issued or transferred.

            (iii) Termination of Status as an Employee, Consultant or Outside
Director. If an Optionee's Continuous Status as an Employee, Consultant or
Outside Director (as the case may be) is terminated for any reason whatever,
such Optionee may, but only within such period of time as provided in the Option
agreement, after the date of such termination (but in no event later than the
date of expiration of the term of such Option as set forth in the Option
agreement and determined by the Committee), exercise the Option to the extent
that such Employee, Consultant or Outside Director was entitled to exercise it
at the date of such termination pursuant to the terms of the Option agreement.
To the extent that such Employee, Consultant or Outside Director was not
entitled to exercise the Option at the date of such termination, or if such
Employee, Consultant or Outside Director does not exercise such Option (which
such Employee, Consultant or Outside Director was entitled to exercise) within
the time specified in the Option agreement, the Option shall terminate.

            (iv) Company Loan or Guarantee. Upon the exercise of any Option and
subject to the pertinent Option agreement and the discretion of the Committee,
the Company may at the request of the Optionee; (A) lend to the Optionee, with
recourse, an amount equal to such portion of the option exercise price as the
Committee may determine; or (B) guarantee a loan obtained by the Optionee from a
third-party for the purpose of tendering the option exercise price.

            9. Non-transferability of Options. An Option granted hereunder shall
by its terms not be sold, pledged, assigned, hypothecated, transferred, or
disposed of in any manner other than by will or the laws of descent and
distribution. An Option may be exercised during the Optionee's lifetime only by
the Optionee.

            10. Adjustments Upon Changes in Capitalization or Merger.

            (a) Capitalization. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock which have
been authorized for issuance under this Plan but as to which no Options have yet
been granted or which have been returned to this Plan upon cancellation or
expiration of an Option, and the number of shares of Common Stock subject to
each outstanding Option, as well as the price per share of Common Stock covered
by


                                       -9-
<PAGE>

each such outstanding Option, shall be proportionately adjusted for any increase
or decrease in the number of issued shares of Common Stock resulting from a
stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock of the Company or the payment of a stock
dividend with respect to the Common Stock. Except as expressly provided herein,
no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, each Option will terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Committee. The Committee may, in the exercise of its sole
discretion in such instances, declare that any Option shall terminate as of a
date fixed by the Committee and give each Optionee the right to exercise his or
her Option as to all or any part of the Optioned Stock, including Shares as to
which the Option would not otherwise be exercisable.

            (c) Sale or Merger. "Sale" means; (i) sale (other than a sale by the
Company) of securities entitled to more than 75 % of the voting power of the
Company in a single transaction or a related series of transactions; or (ii)
sale of substantially all of the assets of the Company; or (iii) approval by the
stockholders of the Company of a reorganization, merger or consolidation of the
Company, as a result of which the persons who were the stockholders of the
Company immediately prior to such reorganization, merger or consolidation do not
own securities immediately after the reorganization, merger or consolidation
entitled to more than 50 % of the voting power of the reorganized, merged or
consolidated company. Immediately prior to a Sale, each Optionee may exercise
his or her option as to all Shares then subject to the Option, regardless of any
vesting conditions otherwise expressed in the Option. Voting power, as used in
this Section 10(c), shall refer to those securities entitled to vote generally
in the election of directors, and securities of the Company not entitled to vote
but which are convertible into, or exercisable for, securities of the Company
entitled to vote generally in the election of directors shall be counted as if
converted or exercised, and each unit of voting securities shall be counted in
proportion to the number of votes such unit is entitled to cast.

            (d) Purchased Shares. No adjustment under this Section 10 shall
apply to any purchased Shares already deemed issued at the time any adjustment
would occur.

            (e) Notice of Adjustments. Whenever the purchase price or the number
or kind of securities issuable upon the exercise of the option shall be adjusted
pursuant to Section 10, the Company shall give each Optionee written notice
setting forth, in reasonable detail, the event requiring the adjustment, the
amount of the adjustment, and the method by which such adjustment was
calculated.


                                      - 10-
<PAGE>

            (f) Certain Cash Payments. If an Optionee would not be permitted to
exercise an Option or any portion thereof (for purposes of this subsection (f)
only, each such Option being referred to as a "Subject Option") or dispose of
the Shares received upon the exercise thereof without loss or liability (other
than a loss or liability for the exercise price, applicable withholding or any
associated transactional cost), or if the Board determines that the Optionee may
not be permitted to exercise the same rights or receive the sane consideration
with respect to the Sale of the Company as a stockholder of the Company with
respect to any Subject Options or portion thereof or the Shares received upon
the exercise thereof, then notwithstanding any other provision of this Plan and
unless the Committee shall provide otherwise in an agreement with such Optionee
with respect to any Subject Options, such Optionee shall have the right, whether
or not the Subject Option is fully exercisable or may be otherwise realized by
the Optionee, by giving notice during the 60-day period from and after a Sale to
the Company, to elect to surrender all or part of any Subject Options to the
Company and to receive cash, within 30 days of such notice, in an amount equal
to the amount by which the "Sale Price" (as defined herein) per share of Common
Stock on the date of such election shall exceed the amount which the Optionee
must pay to exercise the Subject Options per share of Common Stock under such
Subject Options (the "Spread") multiplied by the number of shares of Common
Stock granted under the Subject Options as to which the right granted hereunder
shall be applicable and shall have been exercised; provided, however, that if
the end of such 60-day period from and after a Sale is within six months of the
date of grant of a Subject Option held by an Optionee (except an Optionee who
has deceased during such six month period) who is an officer or director of the
Company (within the meaning of Section 16(b) of the Exchange Act), such Subject
Option shall be canceled in exchange for a payment to the Optionee, effective on
the day which is six months and one day after the date of grant of such Subject
Option, equal to the Spread multiplied by the number of shares of Common Stock
granted under the Subject Option. With respect to any Optionee who is an officer
or director of the Company (within the meaning of Section 16(b) of the Exchange
Act), the 6o-day period shall be extended, if necessary, to include the "window
period" of Rule 16(b)-3 which first commences on or after the date of the Sale,
and the Committee shall have sole discretion, if necessary, to approve the
Optionee's exercise hereunder and the date on which the Spread is calculated may
be adjusted, if necessary, to a later date if necessary to avoid liability to
such Optionee under Section 16(b) , For purposes of the Plan, "Sale Price" means
the higher of (a) the highest reported sales price of a share of Common Stock in
any transaction reported on the principal exchange on which such shares are
listed or on NASDAQ during the 6o-day period prior to and including the date of
a Sale or (b) if the Sale is the result of a tender or exchange offer or a
corporate transaction, the highest price per share of Common Stock paid in such
tender or exchange offer or a corporate transaction, except that, in the case of
Incentive Stock Options, such price shall be based only on the Fair Market Value
of the Common Stock on the date such Incentive Stock Option is exercised. To the
extent that the consideration paid in any such transaction described above
consists all or in part of securities or other non-cash consideration, the value
of such


                                      -11-
<PAGE>

securities or other non-cash consideration shall be determined in the sole
discretion of the Committee.

            (g) Mitigation of Excise Tax. If any payment or right accruing to an
Optionee under this Plan (without the application of this Section, either alone
or together with other payments or rights accruing to the Optionee from the
Company or an affiliate ("Total Payments") would constitute a "parachute
payment" (as defined in Section 280G of the Code and regulations thereunder),
the Committee may in each particular instance determine to (i) reduce such
payment or right to the largest amount or greatest right that will result in no
portion of the amount payable or right accruing under the Plan being subject to
an excise tax under Section 4999 of the Code or being disallowed as a deduction
under Section 28OG of the Code, or (ii) take such other actions, or make such
other arrangements or payments with respect to any such payment or right as the
Committee may determine in the circumstances. Any such determination shall be
made by the Committee in the exercise of its sole discretion, and such
determination shall be conclusive and binding on the Optionee. The Optionee
shall cooperate as may be requested by the Committee in connection with the
Committee's determination, including providing the Committee with such
information concerning such Optionee as the Committee may deem relevant to its
determination.

            11. Time of Granting Options. The date of grant of an Option shall,
for all purposes, be the date on which the Committee makes the determination
granting such Option. Notice of the determination shall be given to each
Employee, Consultant or Outside Director to whom an Option is so granted within
a reasonable time after the date of such grant. If the Committee cancels, with
the consent of Optionee, any Option granted under this Plan, and a new Option is
substituted therefor, the date that the canceled Option was originally granted
shall be the date used to determine the earliest date for exercising the new
substituted Option under Section 7 so that the Optionee may exercise the
substituted Option at the same time as if the Optionee had held the substituted
Option since the date the canceled Option was granted.

            12. Amendment and Termination of Plan.

            (a) Amendment and Termination. The Board or the Committee may amend,
waive or terminate this Plan from time to time in such respects as it shall deem
advisable; provided that, to the extent necessary to comply with Rule 16b-3 or
with Section 422 of the Code (or any other successor or applicable law or
regulation), the Company shall obtain stockholder approval of any Plan amendment
in such a manner and to such a degree as is required by the applicable law, rule
or regulation. Notwithstanding the foregoing, neither the provisions of Section
5(b) of this Plan, nor any other provisions pertaining to the automatic option
grants to Outside Directors, shall be amended more than once every six months,
other than to comport with changes in the Code or other applicable laws or any
rules or regulations promulgated thereunder.


                                      -12-
<PAGE>

            (b) Effect of Amendment or Termination. Any such amendment or
termination of this Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Committee, which agreement must be in writing and signed by the Optionee and
the Company.

            13. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act,
the Exchange Act, and the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the Shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

            As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

            14. Restrictions on Shares. Shares of Common Stock issued upon
exercise of an Option shall be subject to the terms and conditions specified
herein and to such other terms, conditions and restrictions as the Committee in
its discretion may determine or provide in the grant. The Company shall not be
required to issue or deliver any certificates for shares of Common Stock, cash
or other property prior to (a) the listing of such shares on any stock exchange
(or other public market) on which the Common Stock may then be listed (or
regularly traded), (b) the completion of any registration or qualification of
such shares under federal or state law, or any ruling or regulation of any
government body which the Committee determines to be necessary or advisable, and
(c) the satisfaction of any applicable withholding obligation in order for the
Company or an affiliate to obtain a deduction with respect to the exercise of an
Option. The Company may cause any certificate for any share of Common Stock to
be delivered to be properly marked with a legend or other notation reflecting
the limitations on transfer of such Common Stock as provided in this Plan or as
the Committee may otherwise require. The Committee may require any person
exercising an Option to make such representations and furnish such information
as it may consider appropriate in connection with the issuance or delivery of
the shares of Common Stock in compliance with applicable law or otherwise.
Fractional shares shall not be delivered, but shall be rounded to the next lower
whole number of shares.

            15. Stockholder Rights. No person shall have any rights of a
stockholder as to shares of Common Stock subject to an Option until, after
proper exercise of the Option or other action required, such shares shall have
been recorded on the Company's official stockholder records as having been


                                      -13-
<PAGE>

issued or transferred. Subject to the preceding Section and upon exercise of the
Option or any portion thereof, the Company will have thirty (30) days in which
to issue the shares, and the Optionee will not be treated as a stockholder for
any purpose whatsoever prior to such issuance. No adjustment shall be made for
cash dividends or other rights for which the record date is prior to the date
such shares are recorded as issued or transferred in the Company's official
stockholder records, except as provided herein or in an agreement.

            16. Best Efforts To Register. If there has been a public offering,
the Company may register under the Securities Act the Common Stock delivered or
deliverable pursuant to Options on Commission Form S-8 if available to the
Company for this purpose (or any successor or alternate form that is
substantially similar to that form to the extent available to effect such
registration), in accordance with the rules and regulations governing such
forms, as soon as such forms are available for registration to the Company for
this purpose. The Company will, if it so determines, use its good faith efforts
to cause the registration statement to become effective as soon as possible and
will file such supplements and amendments to the registration statement as may
be necessary to keep the registration statement in effect until the earliest of
(a) one year following the expiration of the option period of the last Option
outstanding, (b) the date the Company is no longer a reporting company under the
Exchange Act and (c) the date all Optionees have disposed of all shares
delivered pursuant to any Option. The Company may delay the foregoing actions at
any time and from time to time if the Committee determines in its discretion
that any such registration would materially and adversely affect the Company's
interests or if there is no material benefit to Optionees.

            17. Reservation of Shares. The Company, during the term of this
Plan, will at all times reserve and keep available such number of Shares as
shall be sufficient to permit the exercise of all Options outstanding under this
Plan. The inability of the Company to obtain authority from any regulatory body
having jurisdiction, which authority is deemed by the Company's counsel to be
necessary to the lawful issuance and sale of any Shares hereunder, shall relieve
the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained for any
reason.

            18. Option Agreements. Options shall be evidenced by written Option
agreements in such form as the Committee shall approve.

            19. Information to Optionees. To the extent required by applicable
law, the Company shall provide to each Optionee, during the period for which
such Optionee has one or more Options outstanding, copies of all annual reports
and other information which are provided to all stockholders of the Company.
Except as otherwise noted in the foregoing sentence, the Company shall have no
obligation or duty to affirmatively disclose to any Optionee, and no Optionee
shall have any right to be advised of, any material information regarding the
Company or any Parent or Subsidiary at any time


                                      -14-
<PAGE>

prior to, upon or otherwise in connection with, the exercise of an Option.

            20. Funding . Benefits payable under this Plan to any person shall
be paid directly by the Company. The Company shall not be required to fund or
otherwise segregate assets to be used for payment of benefits under this Plan.

            21. Indemnification. In addition to such other rights of
indemnification as they may have as directors or as members of the Committee,
the members of the Committee shall be indemnified by the Company against the
reasonable expenses, including attorneys' fees, actually and necessarily
incurred in connection with the defense of any action, suit or proceeding, or in
connection with any appeal therein, to which they or any of them may be a party
by reason of any action taken or failure to act under or in connection with this
Plan or any option granted hereunder, and against all amounts paid by them in
settlement thereof (provided such settlement is approved by independent legal
counsel selected by the Company) or paid by them in satisfaction of a judgment
in any such action, suit or proceeding; provided that within 60 days after
institution of any such action, suit or proceeding a Committee member shall in
writing offer the Company the opportunity, at its own expense, to handle and
defend the same. The foregoing right of indemnification shall not be exclusive
and shall be independent of any other rights of indemnification to which such
persons may be entitled under the Company's Certificate of Incorporation or
bylaws, by contract, as a matter of law, or otherwise.

            22. Controlling Law. This Plan shall be governed by the laws of the
State of Delaware applicable to contracts made and performed wholly in Delaware
between Delaware residents.
