<Page>

            (b) On the terms and subject to the conditions contained herein,
Buyer and Company shall provide, or shall cause their Subsidiaries or third
parties designated by it and reasonably acceptable to Seller (such designated
Subsidiaries and third parties, together with the Buyer and Company, being

                                   ARTICLE III

               SERVICES; PAYMENT; INDEPENDENT CONTRACTORS

            SECTION 3.01. SERVICES TO BE PROVIDED. (a) Unless otherwise agreed
by the Parties, Buyer and Seller shall be required to perform, or to cause the
other applicable Service Providers to perform, the Services only in a manner
that is substantially similar in all material respects to the manner in which
such Services were performed for the Company or the Seller, as the case may be,
prior to the Closing Date, and the Services shall be used for substantially the
same purposes and in substantially the same manner as the Services had been used
prior to such date; PROVIDED, HOWEVER, that in no event shall the scope of the
Services required to be performed hereunder exceed that described on Schedule 1
unless otherwise agreed in writing. Each of Seller and the Seller Service
Providers shall act under this Services Agreement solely as an independent
contractor and not as an agent of the Buyer or the Company. Each of Buyer,
Company and the Buyer Service Providers shall act under this Services Agreement
solely as an independent contractor and not as an agent of the Seller.

            (b) If it is necessary for any Seller Service Provider to increase
staffing or acquire equipment or make any investments or capital expenditures to
accommodate an increase in the use of any Seller Service beyond the level of use
of such Seller Service by the Buyer or the Company prior to the Closing Date, as
a result of an increase in volume of the business of the Company or a change in
the manner in which the business of the Company is being conducted, Seller shall
inform Buyer in writing of such increase in staffing level, equipment
acquisitions, investments or capital expenditures before any such cost or
expense is incurred. Upon mutual agreement of the Parties as to the necessity of
any such increase, Buyer (unless Buyer and Seller

<Page>

shall otherwise agree in writing) shall advance to the relevant Seller Service
Providers an amount equal to the actual costs and expenses to be incurred in
connection therewith. If such mutual agreement is not reached, Seller's
obligation to provide or cause to be provided such Seller Service shall be
limited to the level of use of such Seller Service by the Company prior to the
Closing Date.

            (c) The Service Providers shall have the right to shut down
temporarily for any reason specified in Article V (Force Majeure) hereof.

            (d) Buyer and Seller agrees to use their reasonable good faith
efforts to reduce or eliminate their dependency on the Services as soon as is
reasonably practicable.

            (e) If it is necessary for Seller or any other Seller Service
Provider to increase staffing or acquire equipment or make any investments or
capital expenditures or otherwise absorb or incur incremental expenses in order
to provide any Seller Service as a result of the initial conversion or
transition of such Seller Service (including, for example, costs incurred by
Seller or a Seller Service Provider in order to segregate data or systems for
the Company from other data or systems of Seller or the Seller Service
Provider), then Buyer agrees to reimburse the Seller Service Provider in cash,
promptly upon receipt of a written invoice, an amount equal to one half of the
actual costs and expenses incurred by the Seller Service Provider in connection
therewith.

             (f) The parties will use good faith efforts to reasonably cooperate
with each other in all matters relating to the provision and receipt of
Services. Such cooperation shall include obtaining all consents, licenses or
approvals necessary to permit each party to perform its obligations hereunder;
PROVIDED that neither Buyer nor Seller shall be required to pay any amounts to
any third parties or to grant any accommodation, financial or otherwise, to
secure the same. The parties will, for a period of five (5) years after the
Closing Date, maintain documentation supporting the information contained in the
Exhibits and Schedules and cooperate with each other in making such information
available as needed, subject to appropriate confidentiality requirements, in the
event of any tax audit or litigation.

each month by Seller or such other Seller Service Providers designated by Seller
for Seller Services provided to the Buyer and the Company during the preceding
month, and each such statement shall set forth a brief description of such

payable by Buyer net 30 days after the date of such statement. Statements not
paid within such 30-day period shall be subject to late charges, calculated
based on the then current prime or base rate of Chase Manhattan Bank plus one
percentage point, for each month or portion thereof the statement is overdue. In
addition to the charges for the Seller Services provided hereunder, Buyer will
reimburse Seller and the other Seller Service Providers for any and all actual
out-of-pocket ancillary fees, costs, or expenses incurred by Seller or such
Seller Service Providers in connection with providing for the Seller Services
hereunder, including shipping and transportation costs, duties, taxes and other
fees or expenses, where such ancillary

provided for such items on Schedule 1.

            SECTION 3.03. SELLER PAYMENT. Statements will be delivered to Seller
each month by Buyer or such other Buyer Service Providers designated by Buyer
for Buyer Services provided to the Seller during the preceding month, and each
such statement shall set forth a brief description of such Buyer Services and

days after the date of such statement. Statements not paid within such 30-day
period shall be subject to late charges, calculated based on the then current
prime or base rate of Chase Manhattan Bank plus one percentage point, for each
month or portion thereof the statement is overdue. In addition to the charges
for the Buyer Services provided hereunder, Seller will reimburse Buyer and the
other Buyer Service Providers for any and all actual out-of-pocket ancillary
fees, costs, or expenses incurred by Buyer or such Buyer Service Providers in

and transportation costs, duties, taxes and other fees or expenses, where such
ancillary fees, costs or expenses are not specifically included, or exceed, the

ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR
FITNESS FOR ANY PARTICULAR PURPOSE.

            SECTION 3.05. TAXES. The amounts set forth as the applicable
consideration with respect to each Service on Schedule 1 do not include any
sales tax, value added tax, goods and services tax or similar tax (collectively,
"Taxes") and any such Taxes required to be paid by any Service Provider in
connection with this Services Agreement or the performance hereof will be
promptly reimbursed to such Service Providers and such reimbursement shall be in
addition to the amounts required to be paid as set forth on Schedule 1.

            SECTION 3.05. USE OF SELLER SERVICES. Seller shall be required to
provide, or to cause any other Seller Service Provider to provide, Seller
Services only to the Company in connection with its conduct of the business of
the Company as performed prior to the Closing Date. Neither Buyer nor Company
shall resell any Seller Services to any person whatsoever or permit the use of
the Seller Services by any person other than in connection with the conduct of
the business of the Company.

                                   ARTICLE IV

<Page>

            The provision of Services shall commence on the Closing Date and
shall terminate no later than the date indicated for each such Service on
Schedule 1; PROVIDED, HOWEVER, that: (i) any Service may be cancelled or reduced
in amount or any portion thereof upon 30-days' written notice thereof subject to
the requirement that the party receiving the service pay to the Service Provider
the out-of-pocket costs incurred by the Service Provider, as well as the
incremental internal costs incurred by the Service Providers, in each case as a
result of such cancellation, which out-of-pocket and internal costs shall be set
forth in reasonable detail in a written statement provided by the Service
Provider to the recipient of the services; PROVIDED, HOWEVER, that if the
recipient of the services provides the Service Provider with more than 30-days
written notice (such days in excess of the 30-days being collectively referred
to as "additional notice"), then the recipient of the services shall not be
liable for such costs as and to the extent that such additional notice is
sufficient to permit the Service Provider to avoid (through the use of
commercially reasonable means) such costs and (ii) Seller may cease or cause any
other Seller Service Provider to cease providing a Seller Service upon 90-days'
written notice thereof to Buyer to the extent that Seller and the other Seller
Service Providers cease to provide such Seller Services to Seller's similarly
situated Subsidiaries, divisions and business units.

                                    ARTICLE V

                                  FORCE MAJEURE

            The Service Providers shall not be liable for any interruption of
Service or delay or failure to perform under this Services Agreement that is due
to acts of God, acts of a public enemy, acts of a nation or any state,
territory, province or other political division thereof, fires, floods,
epidemics, riots, theft, quarantine restrictions, freight embargoes or other
similar causes beyond the control of the Service Providers. In any such event,
the Service Provider's obligations hereunder shall be postponed for such time as
its performance is suspended or delayed on account thereof. The Service Provider
will promptly notify the recipient of the Service, either orally or in writing,
upon learning of the occurrence of such event of force majeure. Upon the
cessation of the force majeure event, the Service Provider will use reasonable
efforts to resume, or to cause any other relevant Service Provider to resume,
its performance with the least practicable delay.

                                   ARTICLE VI

<Page>

arise out of, relate to or are a consequence of, the performance or
nonperformance by it hereunder or the provision of, or failure to provide, any
Service hereunder, including with respect to loss of profits, business
interruptions or claims of customers (other than, with respect to customers, the
Service Provider in its capacity as a customer). Buyer agrees to indemnify and
hold harmless each Seller Service Provider from and against any such damages
incurred thereby and any costs and expenses thereof arising in connection with
any Seller Service and Seller agrees to indemnify and hold harmless each Buyer
Service Provider from and against any such damages and any costs and expenses
thereof arising in connection with any Buyer Service.

not limited to, the performance or breach hereof, but excluding willful
misconduct or bad faith), or from the sale, delivery, provision or use of any
Service provided under or covered by this Services Agreement, whether in
contract, tort (including negligence and strict liability) or otherwise, shall
not exceed the fees previously paid to such Service Provider under this Services
Agreement in respect of the Service from which such purported liability flows.

            SECTION 6.03. OBLIGATION TO REPERFORM. In the event of any breach of
this Services Agreement by any Service Provider with respect to any error,
defect or breach (which breach Service Provider can reasonably be expected to
reperform in a commercially reasonable manner) in the provision of any Service,
the Service Provider shall correct in all material respects such error, defect
or breach or reperform in all material respects such Service at the request of
the recipient of such Service and at the expense of the Service Provider. The
remedy set forth in this Section 6.03 shall be the only remedy of the recipient
of such Service for any such breach. To be effective, any such request by the
recipient of such Service must (i) specify in reasonable detail the particular
error, defect or breach, (ii) be made no more than one year from the date such
Service was provided and (iii) in the case of a Seller Service be made no less

Subsidiaries, divisions and business units.

forth in this Services Agreement, Buyer and Company hereby releases, each
Service Provider and each of its employees, agents, officers and directors

which options may be granted under the Plan shall be 4,000,000 (four million)
shares (subject to adjustment as provided in Section 9 hereof). If any option

without having been exercised in full, the unpurchased shares of Common Stock
previously subject to such option shall become available for new options.

4.   ADMINISTRATION.

         (a)  The Plan shall be administered by the Committee. The Board shall
annually appoint the members of the Committee at the annual organizing meeting
of the Board.

         (b)  The Board shall fill all vacancies on the Committee and may remove
any member of the Committee at any time with or without cause. The Committee
shall select its own chairman and shall adopt, alter or repeal such rules and
procedures as it may deem proper and shall hold its meetings at such times and
places as it may determine. The Committee shall keep minutes of its meetings.
Action by a majority of the Committee members present at any meeting at which a
quorum is present, or action approved in writing by all members of the Committee
without a meeting, shall constitute the acts of the Committee.

         (c)  Subject to the provisions of the Plan, the Committee shall have
the full and final authority to (i) determine the eligible employees of the
Company and its Subsidiaries to whom, and the times at which, options shall be
granted and the number of shares subject to each option;

                                       2
<PAGE>

(ii) prescribe, amend and rescind rules and regulations relating to the Plan;
(iii) determine the provisions of options granted under the Plan (which need not
be identical) and, with the consent of the holder thereof, amend or modify any
option; (iv) interpret the Plan and the respective options; and (v) make all
other determinations necessary or advisable for administering the Plan. All
determinations and interpretations by the Committee shall be binding upon all
parties. No member of the Committee or the Board shall be liable for any action
or determination made in good faith in respect of the Plan or any option granted
under it.

         (d)  The provisions of this Section 4 shall survive any termination of
the Plan.

5.   ELIGIBILITY FOR AWARD OF OPTIONS.

         (a)  Options may be granted only to officers and other key employees of
the Company and its Subsidiaries. Any reference in the Plan to "employment by
the Company" shall also be deemed to include employment by any Subsidiary of the
Company. Determination by the Committee or the Board as to who are eligible
employees shall be conclusive.

         (b)  A person who is a director of the Company shall not be considered
an officer or employee for the purpose of the Plan solely because he or she is a
director. However, a person who otherwise is an eligible officer or employee
shall not be disqualified by virtue of being a director of the Company or any
Subsidiary.

         (c)  More than one option may be granted to any eligible employee.

6.   OPTION PRICE.

         The purchase price of the Common Stock under each option shall be
determined by the Committee. The purchase price shall be at least 100 percent
(100%) of the Fair Market Value of the Common Stock on the date of grant of
option. The purchase price under an option granted to an officer or employee who
is a Ten Percent Stockholder shall be at least 110% of the Fair Market Value of
the Common Stock on the date of the grant of the option.

7.  ANNUAL LIMITATION ON GRANTS TO ONE OFFICER OR EMPLOYEE.

         No option shall be granted during any calendar year to any individual
under the Plan if the aggregate fair market value (as of the time the option is
granted) of the Common Stock with respect to which incentive stock options are
exercisable for the first time by such individual during any calendar year
(under the Plan and any other plan of the Company, its Parent, if any, and its
Subsidiaries) exceeds $200,000.

8.   TERMS AND EXERCISE OF OPTION.

         (a)  MAXIMUM TEN-YEAR TERMINATION DATE. Each option shall expire no
later than ten years after the date on which it shall have been granted, but the
Committee in its discretion may prescribe a shorter period for any individual
option or options. Any option granted to a person who is a Ten Percent
Stockholder shall terminate no later than five years after the date on which

                                       3
<PAGE>

the option was granted. The date of termination pursuant to this paragraph is
referred to hereinafter as the "termination date of the option."

         (b)  VESTING.  Options shall be exercisable at such times and in such
installments, if any, as the Committee may determine. In the event any option is
exercisable in installments, any shares which may be purchased during any year
or other period which are not purchased during such year or other period may be
purchased at any time or from time to time during any subsequent year or period
during the term of the option unless otherwise provided in the Stock Option
Agreement.

         (c)  MEANS OF EXERCISE OF OPTION.  An option shall be exercised by
written notice to the Secretary or Treasurer of the Company at its then
principal office which is received not later than 5:00 p.m. of the expiration
date. The notice shall specify the number of shares as to which the option is
being exercised and shall be accompanied by payment in full of the purchase
price for such shares. An optionee at his discretion may, in lieu of cash
payment, deliver Common Stock already owned, with a Fair Market Value (on the
date of exercise) equal to the purchase price for the shares being acquired
pursuant to the exercise of the option, as payment for the exercise of any
option. In the event an option is being exercised in whole or in part, pursuant
to Section 8 (f) or (g) hereof by any person other than the optionee, a notice
of election shall be accompanied by proof satisfactory to the Company of the
rights of such person to exercise said option. An optionee shall not, by virtue
of the granting of an option, be entitled to any rights of a shareholder in the
Company and he or she shall not be considered a record holder of shares
purchased by him until the date on which he shall actually be recorded as the
holder of such shares upon the stock records of the Company. The Company shall
not be required to pay to the person exercising the option the cash equivalent
of any fractional share interest unless so determined by the Committee.

         (d)  OPTIONS ARE NONTRANSFERABLE.  No option may be transferred by the
optionee (except in connection with death or disability as provided in Sections
8(f) and (g)).

         (e)  OPTIONS LAPSE THREE MONTHS AFTER TERMINATION OF EMPLOYMENT.  In
the event of the termination of an optionee's employment by the Company and its
Subsidiaries at any time for any reason (excluding disability or death), the
optionee's options and all rights thereunder shall expire three months after the
date of termination of employment. The option shall be exercisable by the
optionee at any time within three months, but only to the extent exercisable by
the optionee on the date of termination of his or her employment.

         (f)  OPTION EXERCISABLE SIX MONTHS AFTER TERMINATION IN EVENT OF
DISABILITY.  In the event the optionee is permanently and totally disabled
(within the meaning of Section 105(d)(4), or any successor section, of the
Code), the optionee's option and all rights thereunder shall expire six months
after the date of termination of employment. The option shall be exercisable by
the optionee (or the optionee's legal representative) at any time within such
six months.

         (g)  OPTION EXERCISABLE SIX MONTHS AFTER DATE OF DEATH.  If an optionee
shall die while in the employ of the Company or any of its Subsidiaries, his
option may be exercised by his designated beneficiaries (or if none have been
effectively designated, by his executor,

                                       4
<PAGE>

administrator or the person to whom rights under his option shall pass by way of
his will or by the laws of descent and distribution) at any time within six (6)
months after date of his death, but only to the extent exercisable by the
optionee at his death. The option shall expire six months after the date of the
optionee's death.

         (h)  NO RIGHT TO CONTINUED EMPLOYMENT.  Nothing in the Plan or in any
option granted pursuant hereto shall confer on any individual any right to
continue in the employ of the Company or any of its Subsidiaries or prevent or
interfere in any way with the right of the Company or its Subsidiaries to
terminate the optionee's employment at any time, with or without cause.

         (i)  OPTIONS MUST BE EVIDENCED BY WRITING.  Each option granted
pursuant to the Plan shall be evidenced by a written Stock Option Agreement,
duly executed by the Company and the optionee, in such form and containing such
provisions as the Committee or Board may from time to time authorize or approve.

9.   ADJUSTMENTS.

         The Stock Option Agreement shall contain appropriate provisions for the
adjustment of the kind and number of shares subject to each outstanding option,
and for the adjustment of the exercise price per share, in the event of any
changes in the outstanding Common Stock of the Company by reason of stock
dividends, stock splits, recapitalization, reorganizations, mergers,
consolidations, combinations or exchanges of shares, and the like. In the event
of any such change or changes in the outstanding Common Stock, and as often as
the same shall occur, the kind and aggregate number of shares available under
the Plan shall be appropriately adjusted by the Committee or Board, whose
determination shall be binding and conclusive.

10.  AMENDMENT AND TERMINATION.

         (a)  Unless the Plan shall have been sooner terminated as provided
herein, it shall terminate on, and no option shall be granted thereunder after
February 14, 2012. The Board may at any time prior to that date alter, suspend
or terminate the Plan as it may deem advisable. Except as otherwise hereinafter
provided, no alteration, suspension or termination of the Plan may, without the
consent of the employee to whom any option shall have theretofore been granted
(or the person or persons entitled to exercise such option under Section 8(f) or
(g) of the Plan), terminate his option or adversely affect his rights
thereunder.

         (b)  Anything herein to the contrary notwithstanding, in the event that
the Board shall at any time declare it advisable to do so in connection with any
proposed sale or conveyance of all or substantially all of the assets of the
Company or of any proposed consolidation or merger of the Company, the Company
may give written notice to the holder of any option that his option may be
exercised only within thirty (30) days after the date of such notice but not
thereafter, and

                                       5
<PAGE>

all rights under said option which shall have not been so exercised shall
terminate at the expiration of such thirty (30) days, provided that the proposed
sale, conveyance, consolidation or merger to which such notice shall relate
shall be consummated within six (6) months after the date of such notice. In the
event such notice shall have been given, any such option may be exercised either
in whole or in part notwithstanding the vested period required under the terms
of the option for the exercise thereof. If such proposed sale, conveyance,
consolidation or merger shall not be consummated within said time period, no
unexercised rights under any option shall be affected by such notice except that
such option may not be exercised between the date of expiration of such thirty
(30) days and the date of the expiration of such six (6) months.

11.  INDEMNIFICATION.

         Any member of the Committee or the Board who is made, or threatened to
be made, a party to any action or proceeding, whether civil or criminal, by
reason of the fact that the member is or was a member is or was a member of the
Committee or the Board insofar as it relates to the Plan shall be indemnified by
the Company, and the Company may advance his related expenses, to the full
extent permitted by law or to any greater extent as provided in the Company's
Certificate of Incorporation or By-Laws or in any agreement between the Company
and the member.

12.  EFFECTIVE DATE OF THE PLAN.

         The Plan shall become effective on, and options may be granted
thereunder after February 14, 2002, provided, however, that if the Plan shall
not be approved by the Committee within 12 months of said date, the Plan and all
options granted thereunder shall be and become null and void, and provided,
further, that no options granted by the Committee may be exercised prior to the
approval of the Plan by the Committee.

13.  EXPENSES.

         The Company shall pay all fees and expenses incurred in connection with
the establishment and administration of the Plan.

14.  GOVERNMENT REGULATIONS.  REGISTRATION AND LISTING OF STOCK.

         (a)  The Plan, and the grant and exercise of options thereunder, and
the Company's obligation to sell and deliver stock under such options, shall be
subject to all applicable federal and state laws, rules and regulations and to
such approvals by any regulatory or governmental agency as may be required.

         (b)  Unless a registration statement under the Securities Act of 1933
and the applicable rules and regulations thereunder (collectively the "Act") is
then in effect with respect to shares issued upon exercise of any option (which
registration shall not be required), the Company shall require that the offer
and sale of such shares be exempt from the registration provisions of said act.
In furtherance of such exemption, the Company may require, as a condition
precedent to the exercise of any option, that the person exercising the option
give to the Company a written

                                       6
<PAGE>

representation and undertaking, satisfactory in the form and substance to the
Company, that he or she is acquiring the shares for his or her own account for
investment and not with a view to the distribution or resale thereof and
otherwise establish to the Company's satisfaction that the offer or sale of the
shares issuable upon the exercise of the option will not constitute or result in
any breach or violation of the Act or any similar state act or statute or any
rules or regulations thereunder. In the event a Registration Statement under the
Act is not then in effect with respect to the shares of Common Stock issued upon
exercise of an option, the Company shall place upon any stock certificate an
appropriate legend referring to the restrictions on disposition under the Act.

         (c) In the event the class of shares issuable upon the exercise of any
option is listed on any national securities exchange, the Company shall not be
required to issue or deliver any certificate for shares upon the exercise of any
options prior to the listing of the shares so issuable on such national
securities exchange and prior to the registration of the same under the Exchange
Act or any similar act or statute.
