the Plan, the maximum aggregate number of shares which may be optioned and sold
under the Plan is 1,000,000 Shares of Common Stock (the “Pool”).  The Shares may be authorized, but unissued,
or reacquired Common Stock.

If an Option expires or becomes unexercisable
without having been exercised in full, the unpurchased Shares which were
subject thereto shall become available for future grant or sale under the Plan
(unless the Plan has terminated). 
Shares that have actually been issued under the Plan shall not be
returned to the Plan and shall not become available for future distribution
under the Plan.

4.             Administration and Grants of Options under the Plan.

(a)           Procedure for Grants.           All grants of Options to Outside Directors under this Plan
shall be automatic and nondiscretionary 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 except as expressly
provided by the Plan.

2

 

(ii)           Each New Outside Director shall be automatically granted
an Option to purchase that number of Shares as shall be determined by the Board
in its sole discretion (the “First Option”) on the date on which such person
first becomes an Outside Director, whether through election by the stockholders
of the Company or appointment by the Board to fill a vacancy; provided,
however, that an Inside Director who ceases to be an Inside Director but who
remains a Director shall not receive a First Option.  If the Board does not establish the number of Shares subject to
the First Option for a given New Outside Director prior to the date of grant
for such First Option, then the number shall be the same as the number of
Shares granted to the immediately preceding New Outside Director.

(iii)          Commencing with the fiscal year beginning January 1, 2002,
each Outside Director shall be automatically granted an Option to purchase that
number of Shares as shall be determined by the Board in its sole discretion (a
“Subsequent Option”) on the date of the Company’s Annual Meeting of
Stockholders upon such Outside Director’s reelection, if on such date, he or
she shall have served on the Board for at least six (6) months.  If the Board does not establish the number
of Shares subject to the Subsequent Option for a given fiscal year, then the
number shall be the same as the number of Shares subject to the Subsequent
Option for the immediately preceding fiscal year (as adjusted pursuant to
Section 10).

(iv)          Notwithstanding the provisions of subsections (ii) and
(iii) hereof, any exercise of an Option granted before the Company has obtained
stockholder approval of the Shares to be issued upon the exercise of such
Option shall be conditioned upon obtaining such stockholder approval.

(v)           The terms of a First Option granted hereunder shall be as
follows:

(A)          the maximum term of a First Option shall be ten (10) years.

(B)           the First Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

(C)           the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the First Option.  In the event that the date of grant of the
First Option is not a trading day, the exercise price per Share shall be the
Fair Market Value on the next trading day immediately following the date of
grant of the First Option.

(D)          subject to Section 10 hereof, 1/48 of the Shares subject to
the First Option shall vest and become exercisable upon the last day of each
month following the date of grant of the First Option until all Shares subject
to the First Option are exercisable.

(vi)          The terms of a Subsequent Option granted hereunder shall be
as follows:

(A)          the maximum term of the Subsequent Option shall be ten (10)
years.

3

 

(B)           the Subsequent Option shall be exercisable only while the
Outside Director remains a Director of the Company, except as set forth in
Sections 8 and 10 hereof.

(C)           the exercise price per Share shall be 100% of the Fair
Market Value per Share on the date of grant of the Subsequent Option.  In the event that the date of grant of the
Subsequent Option is not a trading day, the exercise price per Share shall be
the Fair Market Value on the next trading day immediately following the date of
grant of the Subsequent Option.

(D)          subject to Section 10 hereof, the Subsequent Option shall
be exercisable immediately, in whole or in part.

(vii)         In the event that any Option granted under the Plan would
cause the number of shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the
remaining Shares available for Options grant shall be granted under Options to
the Outside Directors on a pro rata basis. 
No further grants shall be made until such time, if any, as additional
Shares become available for grant under the Plan through action of the Board or
the stockholders to increase the number of Shares which may be issued under the
Plan or through cancellation or expiration of Options previously granted
hereunder.

5.             Eligibility. 
Options may be granted only to Outside Directors.  All Options shall be automatically granted
in accordance with the terms set forth in Section 4 hereof.

The Plan shall not confer upon any Optionee any
right with respect to continuation of service as a Director or nomination to
serve as a Director, nor shall it interfere in any way with any rights which
the Director or the Company may have to terminate the Director’s relationship
with the Company at any time.

6.             Term of Plan. 
The Plan shall become effective upon the earlier to occur of its
adoption by the Board or its approval by the stockholders of the Company.  It shall continue in effect for a term of
ten (10) years ending in 2008 unless sooner terminated under Section 11 of the
Plan.

7.             Form of Consideration.  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall consist of (i)
cash, (ii) check, (iii) other shares which (x) in the case of Shares acquired
upon exercise of an Option, have been owned by the Optionee for more than six
(6) months on the date of surrender, and (y) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised, or (iv) any combination of the foregoing
methods of payment.

8.             Exercise of Option.

(a)           Procedure for Exercise, Rights as a Stockholder.   Any Option granted hereunder shall be
exercisable at such times as are set forth in Section 4 hereof and in
accordance with the schedule set forth in the agreement documenting an
individual Option.

4

 

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 consist of any consideration and method of payment allowable under
Section 7 of the 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. 
A share certificate for the number of Shares so acquired shall be issued
to the Optionee as soon as practicable after exercise of the Option.  No adjustment shall 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 the 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 the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised.

(b)           Termination of Continuous Status as a Director.  Subject to Section 10 hereof, in the event
an Optionee’s status as a Director terminates (other than upon the Optionee’s
death or disability), the Optionee may exercise his or her Option, but only
within ninety (90) days following the date of such termination, and only to the
extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term); provided, however, that in the event that a sale of the Option Stock
received upon exercise of this Option would subject the Director to liability
under Section 16(b) of the Securities and Exchange Act of 1934, as amended,
then the option will terminate on the earlier of (i) fifteenth day after the
last date upon which such sale would result in liability, or (ii) two hundred
ten (210) days following the date of such termination of status as a Director
(but in no event later than the expiration of its ten (10) year term).  To the extent that the Optionee was not
entitled to exercise an Option on the date of such termination, and to the
extent that the Optionee does not exercise such Option (to the extent otherwise
so entitled) within the time specified herein, the Option shall terminate.

(c)           Disability of Optionee.   In the event Optionee’s status as a Director terminates as a
result of disability, the Optionee may exercise his or her Option, but only
within twelve (12) months following the date of such termination, and only to
the extent that the Optionee was entitled to exercise it on the date of such
termination (but in no event later than the expiration of its ten (10) year
term).  To the extent that the Optionee
was not entitled to exercise an Option on the date of the time specified
herein, the Option shall terminate.

(d)           Death of Optionee.   In the event of an Optionee’s death, the Optionee’s estate or a
person who acquired the right to exercise the Option by bequest or inheritance
may exercise the Option, but only within twelve (12) months following the date
of death, and only to the extent that the Optionee was entitled to exercise it
on the date of death (but in no event later than the expiration of its ten (10)
year term).  To the extent that the
Optionee was not entitled to exercise an Option on the date of death, and to
the extent that the Optionee’s estate or a person 

 

5

 

who acquired the right to exercise such Option does
not exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate.

9.             Non-Tranferability of Options.   The Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

10.           Adjustments Upon Changes in Capitalization,
Dissolution, Merger or Asset Sale.

(a)           Changes in Capitalization.   Subject to any required action by the
stockholders of the Company, the number of Shares covered by each outstanding
Option, the number of Shares which have been authorized for issuance under the
Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, and the number of
Shares issuable pursuant to the grant provisions of Section 4 hereof 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, or any other increase or
decrease in the number of issued 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.” 
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 subject to an Option.

(b)           Dissolution or Liquidation.   In the event of the proposed dissolution or
liquidation of the Company, to the extent that an Option has not been
previously exercised, it shall terminate immediately prior to the consummation
of such proposed action.

(c)           Merger or Asset Sale.   In the event of a merger or consolidation of the Company with or
into another corporation or the sale of substantially all of the assets of the
Company, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
“Successor Corporation”).  If an Option
is assumed or substituted for, the Option or equivalent option shall continue
to be exercisable as provided in Section 4 hereof for so long as the Optionee
serves as a Director or a director of the Successor Corporation.  Following such assumption or substitution,
if the Optionee’s status as a Director or director of the Successor
Corporation, as applicable, is terminated other than upon a voluntary
resignation by the Optionee, the Option or option shall become fully
exercisable, including as to Shares for which it would not otherwise be
exercisable.  Thereafter, the Option or
option shall remain exercisable in accordance with Sections 8(b) through (d)
above.

If the Successor Corporation does not assume an
outstanding Option or substitute for it an equivalent option, the Option shall
become fully vested and exercisable, including as to Shares for which it would
not otherwise be exercisable.  In such
event the Board shall notify the 

 

6

 

Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

For purposes of this Section 10(c), an Option shall
be considered assumed if, following the merger, consolidation or sale of
assets, the Option confers the right to purchase or receive, for each Share of
Optioned Stock subject to the Option immediately prior to the merger,
consolidation or sale of assets, the consideration (whether stock, cash, or
other securities or property) received in the merger, consolidation or sale of
assets by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares).  If such consideration received
in the merger, consolidation or sale of assets is not solely common stock of
the successor corporation or its Parent, the Administrator may, with the
consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to 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 merger, consolidation or sale of
assets.

11.           Amendment and Termination of the Plan.

(a)           Amendment and Termination.   Except as set forth in Section 4, the Board
may at any time amend, alter, suspend, or discontinue the Plan, but no
amendment, alteration, suspension or discontinuation shall be made which would
impair the rights of any Optionee under any grant theretofore made, without his
or her consent.  In addition, to the
extent necessary and desirable to comply with any applicable law or regulation,
the Company shall obtain stockholder approval of any Plan amendment in such
manner and to such a degree as required.

(b)           Effect of Amendment or Termination.   Any such amendment or termination of the
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.

12.           Time of Granting Options.   The date of grant of an Option shall, for all purposes, be the
date determined in accordance with Section 4 hereof.

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 of 1933,
as amended, the Exchange Act, the rules and regulations promulgated thereunder,
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 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 representation is required
by any of the aforementioned relevant provisions of law.

7

 

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.

14.           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
satisfy the requirements of the Plan.

15.           Option Agreement.  
Options shall be evidenced by written option agreements in such form as
the Board shall approve.

in the contemplated Transfer by delivering written notice to the GTCR Investors
within 30 days after delivery of the Preferred Sale Notice. If any Non-GTCR
Stockholders have elected to participate in such Transfer, the GTCR Investors
and such Non-GTCR Stockholders will be entitled to sell in the contemplated

Stockholders participating in such sale, and (ii) the number of shares of Common
Stock to be sold in the contemplated Transfer. For purposes of this SECTION

consideration per share of Common Stock to be paid to the Subject Stockholders
by the prospective transferee(s) in the contemplated Transfer, and (y) "the
aggregate number of outstanding shares of Common Stock" shall include the number

     Stockholder Shares to the prospective transferee(s) unless (A) the

     Stockholders at the same price and on the same terms, or (B) the GTCR
     Investors agree to purchase the number of such class of Stockholder Shares
     from the Non-GTCR Stockholders which the Non-GTCR Stockholders would have
     been entitled to sell pursuant to SECTION 4(a) for the consideration per
     share to be paid to the GTCR Investors by the prospective transferee(s).

               (ii)   The Subject Stockholders will use commercially reasonable

provisions of this Agreement. Upon the Transfer of Stockholder Shares pursuant

Stockholder (other than the GTCR Investors) desiring to make such Transfer (the
"TRANSFERRING STOCKHOLDER") will give written notice (the "SALE NOTICE") to the
Company and the holders of Investor Shares (collectively, the "SALE NOTICE
RECIPIENTS"). The Sale Notice will disclose in reasonable detail the identity of
the prospective transferee(s), the number of shares to be transferred and the
terms and conditions of the proposed transfer. Such Transferring Stockholder
will not consummate any Transfer until 45 days after the Sale Notice has been
given to the Sale Notice Recipients, unless the parties to the Transfer have
been finally determined pursuant to this SECTION 5 prior to the expiration of
such 45-day period. (The date of the first to occur of such events is referred
to herein as the "AUTHORIZATION DATE").

          (b)  The Company may elect to purchase all (but not less than all) of
such Stockholder Shares to be transferred upon the same terms and conditions as
those set forth in the Sale Notice by delivering a written notice of such
election to the Transferring Stockholder and the Sale Notice Recipients (other
than the Company) within 20 days after the Sale Notice has been given to the
Company. If the Company has not elected to purchase all of the Stockholder
Shares to be transferred, the holders of Investor Shares may elect to purchase
all (but not less than all) of the Stockholder Shares to be transferred upon the
same terms and conditions as those set forth in the Sale Notice by giving
written notice of such election to such Transferring Stockholder within 25 days
after the Sale Notice has been given to the holders of Investor Shares. If more
than one holder of Investor Shares elects to purchase the Stockholder Shares to
be transferred, the shares of Stockholder Shares to be sold shall be allocated
among the holders of Investor Shares pro rata according to the number of
Investor Shares of the relevant class owned by such holder of Investor Shares on
a fully diluted basis. If neither the Company nor the holders of Investor Shares
elects to purchase all of the Stockholder Shares specified in the Sale Notice,
the Transferring Stockholder may transfer the Stockholder Shares specified in
the Sale Notice at a price and on terms no more favorable to the transferee(s)
thereof than specified in the Sale Notice during the 60-day period immediately
following the Authorization Date. Any

                                        6
<Page>

Stockholder Shares not transferred within such 60-day period will be subject to
the provisions of this SECTION 5 upon subsequent transfer.

          (c)  Notwithstanding anything to the contrary in any other provision
of this Agreement, this SECTION 5 will not apply with respect to (i) any
Transfer of Stockholder Shares by any Stockholder to or among its Affiliates,
(ii) any Transfer of Stockholder Shares to any Investor, (iii) with respect to
an Executive or other Stockholder who is an individual, pursuant to applicable
laws of descent and distribution, (iv) a repurchase of Stockholder Shares by the
Company pursuant to the terms of the Senior Management Agreements, (v) a Public
Sale, (vi) a Sale of the Company, including an Approved Sale (as defined in
SECTION 6(a) hereof), (vii) any Transfer pursuant to SECTION 5(b) of the Senior
Management Agreements, (viii) a Transfer of Stockholder Shares held by the
Pearlstein Purchaser to the Ian Z. Pearlstein Trust and/or the Ivanna V.
Pearlstein Trust, (ix) any Transfers of Stockholder Shares held by the Warrant
Holders in connection with Transfers contemplated by Section 12.05 of the Bridge
Loan Agreement, (x) any Transfer of more than 400,000 Stockholder Shares held by
any Warrant Holder (as such amount is adjusted for stock splits, stock
dividends, stock combinations and similar transactions); provided that if any
Warrant Holder originally acquired less than 400,000 Stockholder Shares (as such
amount is adjusted for stock splits, stock dividends, stock combinations and
similar transactions), such provisions will not apply if and to the extent such
transferee Transfers all, but not less than all, of its Stockholder Shares to
one other Person, or (xi) any Transfer pursuant to the Bajaj Free
Transferability Agreement or the Pearlstein Free Transferability Agreement;
provided that the restrictions contained in this Agreement will continue to be
applicable to the Stockholder Shares after any Transfer pursuant to clauses (i),
(ii), (iii), (vii), (viii), (ix), (x) or (xi) above and the transferee of such
Stockholder Shares shall agree in writing to be bound by the provisions of this
Agreement. Upon the Transfer of Stockholder Shares pursuant to clauses (i),
(ii), (iii), (vii), (viii), (ix), (x) or (xi) of the previous sentence, the
transferees will deliver a written notice to the Company, which notice will
disclose in reasonable detail the identity of such transferee.

          (d)  Notwithstanding anything herein to the contrary, except pursuant
to clause (b) above, in no event shall any Transfer of Stockholder Shares
pursuant to this SECTION 5 be made for any consideration other than cash payable
upon consummation of such Transfer.

          (e)  Notwithstanding the foregoing, no Transfer shall be made to a
Person reasonably determined by the Company to be a competitor of the Company or
any of its subsidiaries.

          (f)  This SECTION 5 shall terminate with respect to each Stockholder
Share upon the earlier of (i) consummation of a Qualified Public Offering, (ii)
the consummation of an Approved Sale and (iii) the date on which such
Stockholder Share has been transferred pursuant to this SECTION 5 (other than
SECTIONS 5(c)(i), (iii), (vii), (viii), (ix), (x) OR (xi)).

          6.   SALE OF THE COMPANY.

          (a)  If the holders of a majority of the Investor Shares approve a
Sale of the Company to an Independent Third Party (an "APPROVED SALE"), each
holder of Stockholder Shares shall vote for, consent to and raise no objections
against such Approved Sale. If the

                                        7
<Page>

Approved Sale is structured as a (i) merger, consolidation or other similar
transaction for which dissenters' rights, appraisal rights or similar rights are
available, each holder of Stockholder Shares shall waive any dissenters' rights,
appraisal rights or similar rights in connection with such merger, consolidation
or other similar transaction for which dissenters' rights, appraisal rights or
similar rights are available or (ii) sale of stock, each holder of Stockholder
Shares shall agree to sell all of his Stockholder Shares and rights to acquire
Stockholder Shares on the terms and conditions approved by the Board and the
holders of a majority of the Investor Shares (voting as a single class) then
outstanding. Each holder of Stockholder Shares shall take all necessary or
desirable actions in connection with the consummation of the Approved Sale as
reasonably requested by the Company.

          (b)  The obligations of the holders of Stockholder Shares with respect
to the Approved Sale of the Company are subject to the satisfaction of the
following conditions: (i) upon the consummation of the Approved Sale, each
holder of a particular class of Stockholder Shares shall receive the same form
of consideration and the same amount of consideration per share, (ii) if any
holders of a class of Stockholder Shares are given an option as to the form and
amount of consideration to be received, each holder of such class of Stockholder
Shares shall be given the same option, and (iii) each holder of then currently
exercisable rights to acquire shares of a class of Stockholder Shares shall be
given an opportunity to either (A) exercise such rights prior to the
consummation of the Approved Sale and participate in such sale as holders of
such class of Stockholder Shares or (B) upon the consummation of the Approved
Sale, receive in exchange for such rights consideration equal to the amount
determined by multiplying (1) the same amount of consideration per share of a
class of Stockholder Shares received by holders of such class of Stockholder
Shares in connection with the Approved Sale less the exercise price per share of
such class of Stockholder Shares or such rights to acquire such class of
Stockholder Shares by (2) the number of shares of such class of Stockholder
Shares represented by such rights.

          (c)  If either the Company or the holders of the Stockholder Shares
enter into a negotiation or transaction for which Rule 506 (or any similar rule
then in effect) promulgated by the Securities and Exchange Commission may be
available with respect to such negotiation or transaction (including a merger,
consolidation or other reorganization), the holders of Stockholder Shares will,
at the request of the Company, appoint a purchaser representative (as such term
is defined in Rule 501) reasonably acceptable to the Company. If any holder of
Stockholder Shares appoints a purchaser representative designated by the
Company, the Company will pay the fees of such purchaser representative, but if
any holder of Stockholder Shares declines to appoint the purchaser
representative designated by the Company such holder will appoint another
purchaser representative if necessary to comply with Rule 506, and such holder
will be responsible for the fees of the purchaser representative so appointed.

          (d)  Holders of Stockholder Shares will bear their pro rata share
(based upon the number of shares sold) of the reasonable out of pocket costs of
any sale of such Stockholder Shares pursuant to an Approved Sale to the extent
such costs are incurred for the benefit of all holders of Stockholder Shares and
are not otherwise paid by the Company or the acquiring party. For purposes of
this SECTION 6(d), costs incurred in exercising reasonable efforts to take all
actions in connection with the consummation of an Approved Sale in accordance
with SECTION 6(a) shall be deemed to be for the benefit of all holders of the
Stockholder Shares. Costs

                                        8
<Page>

incurred by holders of Stockholder Shares on their own behalf will not be
considered costs of the transaction hereunder.

          (e)  This SECTION 6 shall terminate with respect to each Stockholder
Share upon the earlier of (i) the consummation of a Qualified Public Offering
and (ii) the consummation of an Approved Sale.

modification, amendment or waiver of any provision of this Agreement shall be
effective against the Company or the Stockholders unless such modification,
amendment or waiver is approved in writing by the Company and the holders of a
majority of the Investor Shares; provided that in the event that such
modification, amendment or waiver would adversely affect a holder or group of

provision to the contrary contained in this SECTION 11, no modification,
amendment or waiver of the provisions of SECTION 7 above or this sentence shall
be effective against Bajaj or Pearlstein without the prior written consent of
such Person. The failure of any party to enforce any of the provisions of this
Agreement shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

          12.  SEVERABILITY. Whenever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          13.  ENTIRE AGREEMENT. Except as otherwise expressly set forth herein,
this document embodies the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

          14.  SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this
Agreement shall bind and inure to the benefit of and be enforceable by the

the Warrant Holders and each Other Stockholder shall be entitled to enforce
their rights under this Agreement specifically to recover damages by reason of
any breach of any provision of this Agreement and to exercise all other rights
existing in their favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that the Company, each Investor, each Executive, Getronics, the
Warrant Holders and each Other Stockholder may in its sole discretion apply to
any court of law or equity of competent jurisdiction for specific performance
and/or injunctive relief (without

offering of its capital stock to the public pursuant to an effective

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Amendment hereby agree as
follows:

          1.   BOARD OF DIRECTORS. Upon the date hereof, Section 1(a) of the
Stockholders Agreement is amended to read in its entirety as follows:

          (a) From and after the Closing and until the provisions of this
Section 1 cease to be effective, each Stockholder shall vote all of his
Stockholder Shares and any other voting securities of the Company over which
such Stockholder has voting control and shall take all other necessary or
desirable actions within his control (whether in his capacity as a stockholder,
director, member of the board or any committee thereof, or officer of the
Company or otherwise, and including, without limitation, attendance at meetings
in person or by proxy for purposes of obtaining a quorum and execution of
written consents in lieu of meetings), and the Company shall take all necessary
and desirable actions within its control (including, without limitation, calling
special board and stockholder meetings), so that:

               (i)   the  authorized  number of directors on the Company's board
     of directors (the "BOARD") shall be no more than nine directors;

               (ii)  the following persons shall be elected to the Board:

                     (A) two representatives designated by GTCR Fund VII (the
          "GTCR INVESTOR DIRECTORS"), who shall initially be Bruce V. Rauner and
          Philip A. Canfield;

                     (B) two representatives designated by Bajaj (the "EXECUTIVE
          DIRECTORS"), who shall be executive officers of the Company and one of
          whom shall initially be Bajaj; and

                     (C) at such time as GTCR Fund VII designates, up to five
          representatives chosen jointly by GTCR Fund VII and Bajaj (the
          "OUTSIDE DIRECTORS"); PROVIDED that no Outside Director shall be a
          member of the Company's management or an employee or officer of the
          Company or its subsidiaries; PROVIDED further that if GTCR Fund VII
          and Bajaj are unable to agree on the Outside Directors within 10 days
          after the date specified by GTCR Fund VII for electing the Outside
          Directors, then GTCR Fund VII shall, in its sole discretion, designate
          the Outside Directors;

               (iii) the composition of any committee of the Board shall include
     at least one GTCR Investor Director;

               (iv)  a majority of the board of directors of each of the
     Company's subsidiaries (a "SUB BOARD") shall consist of members of the
     Board;

                                        2
<Page>

               (v)   the removal from the Board, a Sub Board or a committee
     (with or without cause) of any GTCR Investor Director or any Outside
     Director shall be upon (and only upon) the written request of GTCR Fund
     VII;

               (vi)  the removal from the Board, a Sub Board or a committee
     (with or without cause) of any Executive Director shall be upon (and only
     upon) the written request of Bajaj; and

               (vii) in the event that any representative designated hereunder
     for any reason ceases to serve as a member of the Board, a Sub Board or a
     committee during his term of office, the resulting vacancy on the Board,
     the Sub Board or such committee shall be filled by a representative
     designated by the person or persons originally entitled to designate such
     director pursuant to SECTION 1(a)(ii) above.

          2.   TERMINATION OF THE STOCKHOLDERS AGREEMENT. Upon the consummation
of the Qualified Public Offering planned by the Company, the Stockholders
Agreement shall terminate and have no further force or effect.

          3.   AMENDMENT AND WAIVER. Except as otherwise provided herein, no
modification, amendment or waiver of any provision of this Amendment shall be
effective unless such modification, amendment or waiver is approved in writing
by the Company and the holders of a majority of the Investor Shares; provided
that in the event that such modification, amendment or waiver would adversely
affect a holder or group of holders of Stockholder Shares, then such amendment
or waiver will require the consent of such holder of Stockholder Shares or a
majority of the Stockholder Shares held by such group of holders adversely
affected. The failure of any party to enforce any of the provisions of this
Amendment shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Amendment in accordance with its terms.

          4.   SEVERABILITY. Whenever possible, each provision of this Amendment
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Amendment is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Amendment shall be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

          5.   ENTIRE AGREEMENT. Except as otherwise expressly set forth herein,
this document embodies the complete agreement and understanding among the
parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

          6.   SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, this
Amendment shall bind and inure to the benefit of and be enforceable by the
Company and its successors and assigns and the Stockholders and any subsequent
holders of Stockholder Shares and the respective successors and assigns of each
of them, so long as they hold Stockholder Shares.

          7.   COUNTERPARTS. This Amendment may be executed in separate
counterparts (including by means of telecopied signature pages), each of which
shall be an original and all of which taken together shall constitute one and
the same agreement.

          8.   REMEDIES. The Company, each Investor, each Executive, Getronics,
the Warrant Holders and each Other Stockholder shall be entitled to enforce
their rights under this Amendment specifically to recover damages by reason of
any breach of any provision of this Amendment and to exercise all other rights
existing in their favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Amendment and that the Company, each Investor, each Executive, Getronics, the
Warrant Holders and each Other Stockholder may in its sole discretion apply to
any court of law or equity of competent jurisdiction for specific performance
and/or injunctive relief (without posting a bond or other security) in order to
enforce or prevent any violation of the provisions of this Amendment.

          9.   GOVERNING LAW. The corporate law of Delaware shall govern all
issues concerning the relative rights of the Company and its stockholders. All
other questions concerning the construction, validity and interpretation of this
Amendment shall be governed by and construed in accordance with the internal
laws of the State of Delaware, without giving effect to any choice of law or
other conflict of law provision or rule (whether of the State of Delaware or any
other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of Delaware.

          10.  DESCRIPTIVE HEADINGS. The descriptive headings of this Amendment
are inserted for convenience only and do not constitute a part of this
Amendment.
