<PAGE>

         C. Amendment to Section 3(a). Section 3(a) of the Agreement is hereby
amended in its entirety to read as follows:

                  "Salary. The Company shall pay Executive as salary
                  compensation for his services of Two Hundred Six Thousand Two
                  Hundred Fifty Dollars ($206,250) per annum ("Base Salary
                  Amount"), less applicable deductions and withholdings,
                  commencing April 16, 2002 and thereafter through the date of
                  the Company's dissolution and liquidation (the "Base Salary
                  Amount"); provided, that in the event that Executive spends
                  less than twenty hours per week engaged in addressing the
                  Company's affairs for three or more consecutive calendar
                  weeks, then the Base Salary Amount shall be adjusted
                  accordingly. The Base Salary Amount shall be paid twice
                  monthly on the first and fifteenth day of each month (or, if
                  such day is not a business day, then the immediately preceding
                  business day)."

         D. Addition of Section 3(c). A new Section 3(c) shall be added to the
Agreement, as follows:

                  "(c) Retention Incentive Bonus. In the event the Company
                  becomes a debtor under the United States Bankruptcy Code,
                  Executive shall become entitled to earn additional
                  compensation in the form of a retention incentive bonus equal
                  to one and one-half percent (1 1/2%) of the fair market value
                  of all assets actually collected by the Company
                  post-bankruptcy petition, which bonus shall be paid as an
                  administrative expense of the Company's bankruptcy estate and
                  shall be subject to the approval of the Bankruptcy Court;
                  provided that, subject to Section 4(a)(iv) hereof, Executive
                  shall only be entitled to a retention incentive bonus to the
                  extent that Executive is employed by the Company at the time
                  of the actual collection of such assets. Executive's right to
                  the retention incentive bonus will attach at the time such
                  assets are actually collected by the Company. It is not
                  necessary, however, that Executive be employed by the Company
                  at the time Executive applies for Bankruptcy Court approval of
                  the retention incentive bonus."

         E. Amendment to Section 4(a). Section 4(a) of the Agreement is hereby
amended by adding a new clause (iv) thereto, as follows:

                  employed by the Company through the date of collection by the
                  Company of all assets."

         F. Full Force and Effect. Except as expressly amended herein, all other
terms and provisions of the Agreement shall remain in full force and effect and
are hereby ratified and confirmed in all respects.

         5.       PARTICIPATION.

         (a)      An eligible Employee may become a participant in the Plan by
completing a subscription agreement on the form provided by the Company and
filing it with the Company's Human Resources Department or the stock brokerage
or other financial services firms designated or approved by the Company from
time to time (each, a "DESIGNATED BROKER") prior to the applicable Offering
Date, unless a later time for filing the subscription agreement is set by the
Board for all eligible Employees with respect to a given Offering, Period. The
subscription agreement shall set forth the percentage of the participant's
Compensation (subject to Section 6(a) below) to be paid as Contributions
pursuant to the Plan.

         (b)      Payroll deductions shall commence on the first full payroll
following the Offering Date and shall end on the last payroll paid on or prior
to the last Purchase Period of the Offering Period to which the subscription
agreement is applicable, unless sooner terminated by the participant as provided
in Section 10.

         (c)      A participant's subscription agreement shall remain in effect
for successive Offering Periods unless modified as provided in Section 6 or
terminated as provided in Section 10.

         6.       METHOD OF PAYMENT OF CONTRIBUTIONS.

         (a)      A participant shall elect to have payroll deductions made on
each payday during the Offering Period in an amount not less than two percent
(2%) and not more than ten percent (10%) (or such other percentage as the Board
may establish from time to time before an Offering Date) of such participant's
Compensation on each payday during the Offering Period. All payroll deductions
made by a participant shall be in full percentage points of Compensation, and
shall be credited to the participant's account under the Plan. A participant may
not make any additional payments into such account.

         (b)      A participant may discontinue his or her participation in the
Plan as provided in Section 10, or, unless otherwise provided by the Company, on
one occasion only during a Purchase Period may increase and on one occasion only
during a Purchase Period may decrease the rate of his or her Contributions with
respect to the ongoing Offering Period by completing and filing with the Company
a new or amended subscription agreement authorizing a change in the payroll
deduction rate. The change in rate shall be effective as of the beginning of the
next calendar month following the date of filing of the new or amended
subscription agreement, if the agreement is filed at least ten (10) business
days prior to such date and, if not, as of the beginning of the next succeeding
calendar month.

         (c)      Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) herein, a
participant's payroll deductions may be decreased during any Offering Period to
0%. Payroll deductions shall re-commence at the rate provided in such
participant's subscription agreement, unless terminated by the participant as
provided in Section 10.

        7.       GRANT OF OPTION.

         (a)      On the Offering Date of each Offering Period, each eligible
Employee participating in such Offering Period shall be granted an option to
purchase on each Purchase Date within the Offering Period a number of Shares of
the Company's Common Stock determined by dividing such Employee's Contributions
accumulated prior to such Purchase Date and retained in the participant's
account as of the Purchase Date by the applicable Purchase Price; provided
however that the maximum number of Shares an Employee may purchase during each
Purchase Period shall be 1,000 Shares (subject to any adjustment pursuant to
Section 19 below), and provided further that such purchase shall be subject to
the limitations set forth in Sections 3(b) and 13.

         (b)      The fair market value of the Company's Common Stock on a given
date (the "FAIR MARKET VALUE") shall be the closing sales price of the Common
Stock for such date (or, in the event that the Common Stock is not traded on
such date, on the immediately preceding trading date), as reported by the
National Association of Securities Dealers Automated Quotation (Nasdaq) National
Market or, if such price is not reported, the mean of the bid and asked prices
per-share of the Common Stock as reported by Nasdaq or, in the event the Common
Stock is listed on a stock exchange, the Fair Market Value per share shall be
the closing sales price on such exchange on such date (or, in the event that the
Common Stock is not traded on such date, on the immediately preceding trading
date), as reported in THE WALL STREET JOURNAL.

         8.       EXERCISE OF OPTION. Unless a participant withdraws from the
Plan as provided in Section 10, his or her option for the purchase of Shares
will be exercised automatically on each Purchase Date of an Offering Period, and
the maximum number of full Shares subject to the option will be purchased at the
applicable Purchase Price with the accumulated Contributions in his or her
account. No fractional Shares shall be issued. Any payroll deductions
accumulated in a participant's account that are not sufficient to purchase a
full Share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 below. The Shares purchased upon exercise
of an option hereunder shall be deemed to be transferred to the participant on
the Purchase Date. During his or her lifetime, a participant's option to
purchase Shares hereunder is exercisable only by him or her.

         9.       DELIVERY. As promptly as practicable after each Purchase Date
of each Offering Period, the number of Shares purchased by each participant upon
exercise of his or her option shall be deposited into an account established in
the participant's name with a Designated Broker.

         (a)      A participant may withdraw all but not less than all the
Contributions credited to his or her account under the Plan at any time prior to
each Purchase Date by giving written notice to the Company or the Designated
Broker, in the form and manner as directed by the Company, at least seven (7)
days prior to the Purchase Date. All of the participant's Contributions credited
to his or her account will be paid to him or her promptly after receipt of his
or her notice of withdrawal and his or her option for the current period will be
automatically terminated, and no further Contributions for the purchase of
Shares will be made during the Offering Period.

         (b)      Upon termination of the participant's Continuous Status as an
Employee prior to the Purchase Date of an Offering Period for any reason,
including retirement or death, the Contributions credited to his or her account
will be returned to him or her or, in the case of his or her death, to the
person or persons entitled thereto under Section 14, and his or her option will
be automatically terminated.

         (c)      In the event an Employee fails to remain in Continuous Status
as an Employee of the Company for at least twenty (20) hours per week during the
Offering Period in which the employee is a participant, he or she will be deemed
to have elected to withdraw from the Plan and the Contributions credited to his
or her account will be returned to him or her and his or her option terminated.

         (d)      A participant's withdrawal from an Offering Period will not
have any effect upon his or her eligibility to participate in a succeeding
Offering Period which commences after the withdrawal or in any similar plan that
may hereafter be adopted by the Company. If a participant withdraws from an
Offering Period, however, payroll deductions shall not resume at the beginning
of any succeeding Offering Periods unless the participant delivers a new or
reinstated subscription agreement to the Company.

         11.      [RESERVED.]

         12.      INTEREST. No interest shall accrue on the Contributions of a

or Common Stock reacquired by the Company and held as treasury shares. If the
Board determines that, on a given Purchase Date, the number of Shares with
respect to which options are to be exercised may exceed (i) the number of Shares
of Common Stock that were available for sale under the Plan on the Offering Date
of the applicable Offering Period, or (ii) the number of shares available for
sale under the Plan on such Purchase Date, the Board may in its sole discretion
provide (x) that the Company shall make a pro rata allocation of the Shares of

                                       6
<PAGE>

Common Stock available for purchase on such Offering Date or Purchase Date, as
applicable, in as uniform a manner as shall be practicable and as it shall
determine in its sole discretion to be equitable among all participants
exercising options to purchase Common Stock on such Purchase Date, and continue
all Offering Periods then in effect, or (y) that the Company shall make a pro
rata allocation of the shares available for purchase on such Offering Date or
Purchase Date, as applicable, in as uniform a manner as shall be practicable and
as it shall determine in its sole discretion to be equitable among all
participants exercising, options to purchase Common Stock on such Purchase Date,
and terminate any or all Offering Periods then in effect pursuant to Section 20
below. The Company may make pro rata allocation of the Shares available on the
Offering Date of any applicable Offering Period pursuant to the preceding
sentence, notwithstanding any authorization of additional Shares for issuance
under the Plan by the Company's stockholders subsequent to such Offering Date.
In the event of a pro-rata allocation, each participant's right to purchase
Shares shall be limited to such pro-rata amount of Shares and the cash balance
of the Contributions credited to his or her account, and the participants shall
not have further rights against the Company or the Board.

         (b)      The participant shall have no interest (including no right to
receive any dividends) or voting right in Shares covered by his or her option
until such option has been exercised.

         (c)      Shares to be delivered to a participant under the Plan will be
registered in the name of the participant or in the name of the participant and
his or her spouse.

         14.      ADMINISTRATION. The Board, or a committee named by the Board,
shall supervise and administer the Plan. The Board or committee shall have full
and exclusive discretionary authority to construe, interpret, and apply the
terms of the Plan, to determine eligibility, to adjudicate all disputed claims
under the Plan, to adopt, amend and rescind any rules deemed appropriate for the
administration of the Plan, and to make all other determinations necessary or
advisable for the administration of the Plan. Every finding, decision, and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties. To the extent permitted
by law, no member of the Board (or committee) shall be liable for any action or
determination made in good faith with respect to the Plan or any participant.

         15.      DESIGNATION OF BENEFICIARY.

         (a)      A participant may designate a beneficiary who is to receive
any Shares and cash, if any, from the participant's account under the Plan in
the event of such participant's death subsequent to the end of a Purchase Period
but prior to delivery to him or her of such Shares and cash. In addition, a
participant may designate a beneficiary who is to receive any cash from the
Participant's account under the Plan in the event of such participant's death
prior to the Purchase Date of an Offering Period. If a participant is married
and the designated beneficiary is not the spouse, spousal consent shall be
required for such designation to be effective. Beneficiary designations under
this Section 15(a) shall be made in the form and in the manner as directed by
the Company's Human Resources Department.

                                       7
<PAGE>
         (b)      Such designation of beneficiary may be changed by the
participant (and his or her spouse, if any) at any time by written notice in
accordance with Section 15(a). In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such Shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such Shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate. Any such delivery or
payment shall fully discharge the Company, the Designated Subsidiaries, the
Board, any committee, and all of their employees or representatives with respect
to any liability or obligation to the participant and other persons.

         16.      TRANSFERABILITY. Neither Contributions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive Shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 15) by the participant. Any such attempt
at assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds in
accordance with Section 10.

         17.      USE OF FUNDS. All Contributions received or held by the
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such Contributions.

         18.      REPORTS. Individual accounts will be maintained for each
participant in the Plan. Statements of account will be provided to participating
Employees at least annually, which statements will set forth the amounts of
Contributions, the per Share Purchase Price, the number of Shares purchased, and
the remaining cash balance, if any.

         19.      ADJUSTMENTS UPON CHANGES IN CAPITALIZATION; CORPORATE
TRANSACTIONS.

         (a)      ADJUSTMENT. Subject to any required action by the stockholders
of the Company, the number of Shares covered by each option under the Plan that
has not yet been exercised and the number of Shares that have been authorized
for issuance under the Plan but have not yet been placed under option
(collectively, the "RESERVES"), as well as the maximum number of shares of
Common Stock that may be purchased by a participant in a Purchase Period, the
number of shares of Common Stock set forth in Section 13(a)(i) above, and the
price per Share of Common Stock covered by each option under the Plan that has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued Shares resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common Stock
(including any such change in the number of Shares of Common Stock effected in
connection with a change in domicile of the Company), or any other increase or
decrease in the number of Shares effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except

                                       8

<PAGE>

as expressly provided herein, no issue 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 subject to an option.

         (b)      CORPORATE TRANSACTIONS. In the event of a proposed dissolution
or liquidation of the Company, any Purchase Period and Offering Period then in
progress will terminate immediately prior to the consummation of such action,
unless otherwise provided by the Board. In the event of a Corporate Transaction,
each option outstanding under the Plan shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or Subsidiary of
such successor corporation. In the event that the successor corporation refuses
to assume or substitute for outstanding options, each Purchase Period and
Offering Period then in progress shall be shortened and a new Purchase Date
shall be set (the "NEW PURCHASE DATE"), as of which date any Purchase Period and
Offering Period then in progress will terminate. The New Purchase Date shall be
on or before the date of consummation of the transaction and the Board shall
notify each participant in writing, at least ten (10) days prior to the New
Purchase Date, that the Purchase Date for his or her option has been changed to
the New Purchase Date and that his or her option will be exercised automatically
on the New Purchase Date, unless prior to such date he or she has withdrawn from
the Offering Period as provided in Section 10. For purposes of this Section 19,
an option granted under the Plan shall be deemed to be assumed, without
limitation, if, at the time of issuance of the stock or other consideration upon
a Corporate Transaction, each holder of an option under the Plan would be
entitled to receive upon exercise of the option the same number and kind of
shares of stock or the same amount of property, cash or securities as such
holder would have been entitled to receive upon the occurrence of the
transaction if the holder had been, immediately prior to the transaction, the
holder of the number of Shares of Common Stock covered by the option at such
time (after giving effect to any adjustments in the number of Shares covered by
the option as provided for in this Section 19); provided, however, that if the
consideration received in the transaction is not solely common stock of the
successor corporation or its parent (as defined in Section 424(e) of the Code),
the Board may, with the consent of the successor corporation, provide for the
consideration to be received upon exercise of the option to be solely common
stock of the successor corporation or its parent equal in Fair Market Value to
the per Share consideration received by holders of Common Stock in the
transaction.

         The Board may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per Share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings, or other increases or reductions of Shares of its outstanding Common
Stock, and in the event of the Company's being consolidated with or merged into
any other corporation.

         20.      AMENDMENT OR TERMINATION.

         (a)      The Board may at any time and for any reason terminate or
amend the Plan. Except as provided in Section 19 or in this Section 20, no such
termination of the Plan may affect options previously granted, provided that the
Plan or an Offering Period may be terminated by the Board on a Purchase Date or
by the Board's setting a new Purchase Date with respect to an Offering Period
and Purchase Period then in progress if the Board determines that termination of
the Plan and/or the Offering Period is in the best interests of the Company and
the stockholders, or if continuation of the Plan and/or the Offering Period
would cause the Company to incur adverse accounting charges as a result of a
change after the effective date of the Plan in the generally accepted accounting
rules applicable to the Plan. Except as provided in Section 19 or in this
Section 20, no amendment to the Plan shall make any change in any option
previously granted that adversely affects the rights of any participant.

         (b)      Without stockholder consent and without regard to whether any
participant rights may be considered to have been adversely affected, the Board
(or its committee) shall be entitled to change the Offering Periods and Purchase
Periods for any reason (including any determination by the Board that the
failure to make such change could cause the Company to incur adverse accounting
charges), limit the frequency and/or number of changes in the amount withheld
during an Offering Period, change or eliminate any automatic Offering Period
withdrawal and re-enrollment feature of the Plan, establish the exchange ratio
applicable to amounts withheld in a currency other than U.S. dollars, permit
payroll withholding in excess of the amount designated by a participant in order
to adjust for delays or mistakes in the Company's processing of properly
completed withholding elections, establish reasonable waiting and adjustment
periods and/or accounting and crediting procedures to ensure that amounts
applied toward the purchase of Common Stock for each participant properly
correspond with amounts withheld from the participant's Compensation, and
establish such other limitations or procedures as the Board (or its committee)
determines in its sole discretion advisable that are consistent with the Plan.

         (c)      To facilitate the extension of an employee stock purchase
program to employees of the Company and any Designated Subsidiaries located
outside of the United States, the Board may amend the Plan, or establish
additional employee stock purchase arrangements in the nature of "sub" or
"mirror" plans, without stockholder approval, for the purpose of complying with
applicable foreign laws and practices. Any Shares issued with respect to any
such foreign employee stock purchase program shall count against the Share
limitations of this Plan including Sections 7 and 13.

         (d)      To the extent necessary to comply with Rule 16b-3 under the
Exchange Act, Section 423 of the Code, or any other applicable law, regulation,
or stock exchange rule, the Company shall obtain stockholder approval in such a
manner and to such a degree as so required.

         21.      NOTICES. All notices or other communications by a participant
to the Company under or in connection with the Plan shall be deemed to have been
duly given when received in the form specified by the Company at the location,
or by the person, designated by the Company for the receipt thereof. In the
absence of any such designation, all notices or other communications by a
participant must be received by the Vice-President of Finance or the
Vice-President of Human Resources.

         22.      CONDITIONS UPON ISSUANCE OF SHARES. Shares shall not be issued
with respect to an option unless the exercise of such option and the issuance
and delivery of such Shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Exchange Act, the rules and regulations
promulgated thereunder, applicable state securities laws, 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 make appropriate representations (including
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
applicable provisions of law.

         23.      TERM OF PLAN; EFFECTIVE DATE. Subject to stockholder approval,
the Plan shall become effective July 1, 2002. It shall continue in effect for a
term of ten (10) years unless sooner terminated under Section 20.

         24.      ADDITIONAL RESTRICTIONS OF RULE 16B-3. The terms and
conditions of options granted hereunder to, and the purchase of Shares by,
persons subject to Section 16 of the Exchange Act shall comply with the
applicable provisions of Rule 16b-3. This Plan shall be deemed to contain, and
such options shall contain, and the Shares issued upon exercise thereof shall be
subject to, such additional conditions and restrictions as may be required by
Rule 16b-3 to qualify for the maximum exemption from Section 16 of the Exchange
Act with respect to Plan transactions.

         25.      NOTICE OF DISQUALIFYING DISPOSITIONS. By electing to
participate in the Plan, each participant agrees to notify the Company in
writing immediately after the participant sells, transfers or otherwise disposes
of any Shares acquired under the Plan, if such disposition occurs within the
earlier of (i) two (2) years of the Offering Date, or (ii) one (1) year of the
Purchase Date, associated with such Shares. Each participant further agrees to
provide any information about a disposition of Shares as may be requested by the
Company to assist it in complying with any applicable tax laws.

         26.      WITHHOLDING OF TAXES. Each participant must make adequate
provision for all applicable federal, state, or other tax withholding
obligations which may arise upon the exercise of any option or the disposition
of any Shares.

         27.      NO EMPLOYMENT RIGHTS. The Plan does not create, directly or
indirectly, any right for the benefit of any employee or class of employees to
purchase any shares from the Company (other than as expressly provided in, and
subject to the terms and conditions of, the Plan), or create in any employee or
class of employees any right with respect to continuation of employment by the
Company or any Subsidiary, and it shall not be deemed to interfere in any way
with the Company's or any Subsidiary's right to terminate, or otherwise modify,
an employee's employment at any time.

                                       11
<PAGE>

         28.      OFFSETS. To the extent permitted by law, the Company shall
have the absolute right to withhold any amounts payable to any participant under
the terms of the Plan to the extent of any amount owed for any reason by such
participant to the Company or any Subsidiary and to set off and apply the
amounts so withheld to payment of any such amount owed to the Company or any
Subsidiary, whether or not such amount shall then be immediately due and payable
and in such order or priority as among such amounts owed as the Board or its
committee, in its sole discretion, shall determine.

         29.      CAPTIONS. The captions of the sections and paragraphs of this
Plan have been inserted solely as a matter of convenience and in no way define
or limit the scope or intent of any provision of the Plan. References to

be deemed to include the plural unless a different meaning is required by the
context.

         30.      GOVERNING LAW. The internal laws of the State of Delaware
shall govern all matters relating to this Plan except to the extent superseded
by the laws of the United States.
