         THIS COMMON STOCK PURCHASE WARRANT AND THE SHARES THAT MAY BE PURCHASED
         HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR
         UNDER THE SECURITIES LAWS OF ANY STATE. THIS COMMON STOCK PURCHASE
         WARRANT HAS BEEN ACQUIRED FOR INVESTMENT PURPOSES AND NOT WITH A VIEW
         TO DISTRIBUTION, AND THIS COMMON STOCK PURCHASE WARRANT AND THE SHARES
         THAT MAY BE PURCHASED HEREUNDER MAY NOT BE SOLD OR OFFERED FOR SALE IN
         THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
         ACT OF 1933, AND REGISTRATION OR QUALIFICATION UNDER APPLICABLE STATE

         2002, AMONG DIGITALNET HOLDINGS, INC. AND CERTAIN OF THE COMPANY'S
         STOCKHOLDERS, AS AMENDED AND MODIFIED FROM TIME TO TIME. A COPY OF SUCH

                            DIGITALNET HOLDINGS, INC.

                          COMMON STOCK PURCHASE WARRANT

Date of Issuance:                                          Certificate No.

         THIS IS TO CERTIFY that BANC OF AMERICA MEZZANINE CAPITAL LLC, a
Delaware limited liability company, and its transferees, successors and assigns
(the "Holder"), for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, is entitled to purchase from DIGITALNET
HOLDINGS, INC., a Delaware corporation (the "COMPANY"), at the price of $0.01
per share (the "EXERCISE PRICE"), at any time after the date hereof (the
"COMMENCEMENT DATE") and expiring on November 26, 2012 (the "EXPIRATION DATE"),
758,952 shares of the fully paid and nonassessable Common Stock, par value
$0.001 per share ("COMMON STOCK"), of the Company (as such number may be
adjusted as provided herein). The 758,952 shares of Common Stock which may be
purchased pursuant to this Warrant are referred to herein as the "AGGREGATE
NUMBER", which represents the number of shares that as of the date hereof would
constitute 1.29% of all issued and outstanding shares of Common Stock of the
Company on a Fully Diluted basis, which for these purposes assumes (a) the full
exercise of this Warrant and all other outstanding warrants or other Convertible
Securities and (b) the full exercise of options granted or to be granted under
the Stock Option

                                       1

<Page>

Plan representing the right to purchase 987,328 shares of the Common Stock of
the Company on a Fully Diluted basis as of the date hereof

         Capitalized terms used herein shall have the meanings ascribed to such
terms in Section 11 hereof unless otherwise defined herein.

SECTION 1. THE WARRANT; TRANSFER AND EXCHANGE.

         (a) THE WARRANT. This Common Stock Purchase Warrant (the "WARRANT") is
issued under and pursuant to the Bridge Loan Agreement. This Warrant and the
rights and privileges of the Holder hereunder may be exercised by the Holder in
whole or in part as provided herein; shall survive any termination of the Bridge
Loan Agreement; and, as more fully set forth in Sections 1(b) and 8 hereof, may,
subject to the terms and conditions of the Stockholders Agreement and this
Warrant, be transferred by the Holder to any other Person or Persons who meet
the requirements set forth herein or therein at any time or from time to time,
in whole or in part, regardless of whether the Holder retains any or all rights
under the Bridge Loan Agreement.

         (b) TRANSFER AND EXCHANGES. The Company shall initially record this
Warrant on a register to be maintained by the Company with its other stock books
and subject to Section 8 hereof, from time to time thereafter shall reflect the
transfer of this Warrant on such register when surrendered for transfer in
accordance with the terms hereof and properly endorsed, accompanied by
appropriate instructions, and further accompanied by payment in cash or by
check, bank draft or money order payable to the order of the Company, in United
States currency, of an amount equal to any stamp or other tax or governmental
charge or fee required to be paid in connection with the transfer thereof. Upon
any such transfer, a new warrant or warrants shall be issued to the transferee
and the Holder (in the event the Warrant is only partially transferred) and the
surrendered warrant shall be canceled. Each such transferee shall succeed to all
of the rights of the Holder under the Bridge Loan Agreement to the extent and in
proportion to the Bridge Notes held by such transferee. This Warrant may be
exchanged at the option of the Holder, when surrendered at the Principal Office
of the Company, for another warrant or other warrants of like tenor and
representing in the aggregate the right to purchase a like number of shares of
Common Stock.

SECTION 2. EXERCISE.

         (a) RIGHT TO EXERCISE. At any time after the Commencement Date and on
or before the Expiration Date, the Holder, in accordance with the terms hereof,
may exercise this Warrant, in whole at any time or in part from time to time, by
delivering this Warrant to the Company during normal business hours on any
Business Day at the Company's Principal Office, together with the Election to
Purchase, in the form attached hereto AS EXHIBIT A and made a part hereof (the
"ELECTION TO PURCHASE"), duly executed, and payment of the Exercise Price per
share for each share purchased, as specified in the Election to Purchase. The
aggregate Exercise Price (the "AGGREGATE EXERCISE PRICE") to be paid for the
shares to be purchased (the "EXERCISE AMOUNT") shall equal the product of (i)
the Exercise Amount multiplied by (ii) the Exercise Price. If the Expiration
Date is not a Business Day, then this Warrant may be exercised on the next
succeeding Business Day.

                                       2

<Page>

         (b) PAYMENT OF THE AGGREGATE EXERCISE PRICE. Payment of the Aggregate
Exercise Price shall be made to the Company in cash or other immediately
available funds or as provided in Section 2(c), or a combination thereof. In the
case of payment of all or a portion of the Aggregate Exercise Price pursuant to
Section 2(c), the direction by the Holder to make a "Cashless Exercise" shall
serve as accompanying payment for that portion of the Exercise Price.

         (c) CASHLESS EXERCISE. The Holder shall have the right to pay all or a
portion of the Aggregate Exercise Price by making a "Cashless Exercise", in
which case the portion of the Aggregate Exercise Price to be so paid shall be
paid by reducing the number of shares of Common Stock otherwise issuable
pursuant to the Election to Purchase by an amount equal to (i) the Aggregate
Exercise Price to be so paid divided by (ii) the Fair Market Value Per Share.

         (d) ISSUANCE OF SHARES OF COMMON STOCK. Upon receipt by the Company of
this Warrant at its Principal Office in proper form for exercise, and
accompanied by the Election to Purchase and payment of the Aggregate Exercise
Price as aforesaid, the Holder shall be deemed to be the holder of record of the
shares of Common Stock issuable upon such exercise, notwithstanding that
certificates representing such shares of Common Stock may not then be actually
delivered. Within 3 Business Days after such surrender of this Warrant, delivery
of the Election to Purchase and payment of the Aggregate Exercise Price as
aforesaid, the Company shall issue and cause to be delivered to, or upon the
written order of, the Holder (and in such name or names as the Holder may
designate) a certificate or certificates for the Exercise Amount, subject to any
reduction as provided in Section 2(c) for a Cashless Exercise.

         (e) FRACTIONAL SHARES. The Company may, but shall not be required to,
deliver fractions of shares of Common Stock upon exercise of this Warrant. If
any fraction of a share of Common Stock would be deliverable upon an exercise of
this Warrant, the Company may, within 3 Business Days of the proper exercise and
in lieu of delivering such fraction of a share of Common Stock, make a cash
payment to the Holder in an amount equal to the same fraction of the Fair Market
Value Per Share determined as of the Business Day immediately preceding the date
of exercise of this Warrant.

         (f) PARTIAL EXERCISE. In the event of a partial exercise of this
Warrant, the Company shall issue to the Holder a Warrant in like form for the
unexercised portion thereof which has not expired.

SECTION 3. PAYMENT OF TAXES. The Company shall pay all stamp taxes attributable
to the initial issuance of shares or other securities issuable upon the exercise
of this Warrant or issuable pursuant to Section 6 hereof, excluding any tax or
taxes which may be payable because of the transfer involved in the issuance or
delivery of any certificates for shares or other securities in a name other than
that of the Holder in respect of which such shares or securities are issued.

SECTION 4. REPLACEMENT WARRANT. In case this Warrant is mutilated, lost, stolen
or destroyed, the Company shall issue and deliver in exchange and substitution
for and upon cancellation of the mutilated Warrant, or in lieu of and in
substitution for the Warrant lost, stolen

                                       3

<Page>

or destroyed, a new Warrant of like tenor and representing an equivalent right
or interest, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction of such Warrant and upon receipt of
indemnity reasonably satisfactory to the Company, provided that if the Holder is
a financial institution or other institutional investor its own agreement shall
be satisfactory.

SECTION 5. RESERVATION OF COMMON STOCK AND OTHER COVENANTS.

         (a) RESERVATION OF AUTHORIZED COMMON STOCK. The Company shall at all
times reserve and keep available out of the aggregate of its authorized but
unissued shares, free of preemptive rights, such number of its duly authorized
shares of Common Stock, or other stock or securities deliverable pursuant to
Section 6 hereof, as shall be sufficient to enable the Company at any time to
fulfill all of its obligations under this Warrant.

         (b) AFFIRMATIVE ACTIONS TO PERMIT EXERCISE AND REALIZATION OF BENEFITS.
If any shares of Common Stock reserved or to be reserved for the purpose of the
exercise of this Warrant, or any shares or other securities reserved or to be
reserved for the purpose of issuance pursuant to Section 6 hereof, require
registration with or approval of any governmental authority under any federal or
state law (other than securities laws) before such shares or other securities
may be validly delivered upon exercise of this Warrant, then the Company
covenants that it will, at its sole expense, secure such registration or
approval, as the case may be (including but not limited to approvals or
expirations of waiting periods required under the Hart Scott Rodino Antitrust
Improvements Act).

         (c) REGULATORY REQUIREMENTS AND RESTRICTIONS. In the event of any
reasonable determination by the Holder that, by reason of any existing or future
federal or state law, statute, rule, regulation, guideline, order, court or
administrative ruling, request or directive (whether or not having the force of
law and whether or not failure to comply therewith would be unlawful)
(collectively, a "REGULATORY REQUIREMENT"), the Holder is effectively restricted
or prohibited from holding this Warrant or the Warrant Shares (including any
shares of capital stock or other securities distributable to the Holder in any
merger, reorganization, readjustment or other reclassification), or otherwise
realizing upon or receiving the benefits intended under this Warrant, the
Company shall, and shall use its reasonable best efforts to have its
stockholders, take such action as the Holder and the Company shall jointly agree
in good faith to be reasonably necessary to permit the Holder to comply with
such Regulatory Requirement. The reasonable costs of taking such action, whether
by the Company, the Holder or otherwise, shall be borne by the Company.

         (d) VALIDLY ISSUED SHARES. The Company covenants that all shares of
Common Stock that may be issued upon exercise of this Warrant, assuming full
payment of the Aggregate Exercise Price (including those issued pursuant to
Section 6 hereof), shall upon delivery by the Company be duly authorized and
validly issued, fully paid and nonassessable, free from all stamp taxes, liens
and charges with respect to the issue or delivery thereof and otherwise free of
all other security interests, encumbrances and claims of any nature whatsoever
(other than security interests, encumbrances and claims to which the Holder is
subject prior to the issuance of the Warrant and other transfer restrictions
described herein).

SECTION 6. ADJUSTMENTS TO AGGREGATE NUMBER.

         Under certain conditions, the Aggregate Number is subject to adjustment
as set forth in this Section 6. No adjustments shall be made under this Section
6 as a result of (a) the issuance by the Company of the (i) Warrant Shares upon
exercise of this Warrant and the Escrow Warrant and (ii) the Common Stock upon
conversion of the Preferred Stock, (b) the issuance of shares of Common Stock
(or options related thereto) upon the exercise of options granted or to be
granted under a Stock Option Plan (subject to adjustment for any combinations,
consolidations, stock distributions or stock dividends with respect to the
Common Stock), (c) the issuance of shares of Common Stock pursuant to a bona
fide underwritten public offering registered under the Securities Act, (d) the
issuance of shares of Common Stock as consideration in connection with the
acquisition of all or a controlling interest in another business (whether by
merger, purchase of stock or assets or otherwise) if such issuance is approved
by the Board of Directors, (e) and the issuance of shares of Common Stock to
lenders and other financial sources (other than the Sponsor and its Affiliates)
in connection with any borrowings, credit arrangements, equipment financings or
similar transactions that are approved by the Board of Directors, but only if
upon consummation of such transaction all Bridge Loan Obligations and, if
applicable, Rollover Notes will be or have been paid in full in cash (the
"EXEMPT ISSUANCES").

         (a) ADJUSTMENTS. The Aggregate Number, after taking into consideration
any prior adjustments pursuant to this Section 6, shall be subject to adjustment
from time to time as follows and, thereafter, as adjusted, shall be deemed to be
the Aggregate Number hereunder.

                  (i) STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. In case at
any time or from time to time the Company shall:

                           (A) issue to the holders of its Common Stock a
dividend payable in, or other distribution of, Common Stock (a "STOCK
DIVIDEND"),

                           (B) subdivide its outstanding shares of Common Stock
into a larger number of shares of Common Stock, including without limitation by
means of a stock split (a "STOCK SUBDIVISION"), or

                           (C) combine its outstanding shares of Common Stock
into a smaller number of shares of Common Stock (a "STOCK COMBINATION"),

then the Aggregate Number in effect immediately prior thereto shall be (1)
proportionately increased in the case of a Stock Dividend or a Stock Subdivision
and (2) proportionately decreased in the case of a Stock Combination. In the
event the Company shall declare or pay, without consideration, any dividend on
the Common Stock payable in any right to acquire Common Stock for no
consideration, then the Company shall be deemed to have made a Stock Dividend in
an amount of shares equal to the maximum number of shares issuable upon exercise
of such rights to acquire Common Stock.

                                       5

<Page>

                  (ii) OTHER DISTRIBUTIONS. In case at any time or from time to
time the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive any dividend or other distribution
(collectively, a "Distribution") of:

                           (A) cash,

                           (B) any evidences of its indebtedness (other than
                  Convertible Securities), any shares of its Capital Stock
                  (other than additional shares of Common Stock or Convertible
                  Securities) or any other securities or property of any nature
                  whatsoever (other than cash) or

                           (C) any options, warrants or other rights to
                  subscribe for or purchase any of the following: any evidences
                  of its indebtedness (other than Convertible Securities), any
                  shares of its Capital Stock (other than additional shares of
                  Common Stock or Convertible Securities) or any other
                  securities or property of any nature whatsoever,

then the Holder shall be entitled to elect by written notice to the Company to
receive (1) immediately and without further payment the cash, evidences of
indebtedness, stock, securities, other property, options, warrants and/or other
rights (or any portion thereof) to which the Holder would have been entitled by
way of such Distribution as if the Holder had exercised this Warrant immediately
prior to such Distribution or (2) upon the exercise of this Warrant at any time
on or after the taking of such record in accordance with the terms hereof, the
number of Warrant Shares to be received upon exercise of this Warrant determined
as stated herein and, in addition and without further payment, the cash,
evidences of indebtedness, stock, securities, other property, options, warrants
and/or other rights (or any portion thereof) to which the Holder would have been
entitled by way of such Distribution and subsequent dividends and distributions
through the date of exercise as if such Holder (x) had exercised this Warrant
immediately prior to such Distribution and (y) had retained the Distribution in
respect of the Common Stock and all subsequent dividends and distributions of
any nature whatsoever in respect of any stock or securities paid as dividends
and distributions and originating directly or indirectly from such Common Stock.

         A reclassification of the Common Stock into shares of Common Stock and
shares of any other class of stock shall be deemed a Distribution by the Company
to the holders of its Common Stock of such shares of such other class of stock
and, if the outstanding shares of Common Stock shall be changed into a larger or
smaller number of shares of Common Stock as a part of such reclassification,
such event shall be deemed a Stock Subdivision or Stock Combination, as the case
may be, of the outstanding shares of Common Stock within the meaning of Section
6(a)(i) hereof.

                  (iii) ISSUANCE OF COMMON STOCK. If at any time or from time to
time the Company shall (except as hereinafter provided in this Section
6(a)(iii)) issue or sell any additional shares of Common Stock for a
consideration per share less than the Trigger Price Per Share, then, effective
on the date specified below, the Aggregate Number shall be adjusted by
multiplying (A) the Aggregate Number immediately prior thereto by (B) a
fraction, the

                                       6

<Page>

numerator of which shall be the sum of the number of shares of Common Stock
outstanding immediately prior to the issuance of such additional shares of
Common Stock, the number of shares of Common Stock issuable upon the conversion
or exercise of options, warrants, rights or Convertible Securities (whether or
not then exercisable), and the number of such additional shares of Common Stock
so issued and the denominator of which shall be the sum of the number of shares
of Common Stock outstanding immediately prior to the issuance of such additional
shares of Common Stock, the number of shares of Common Stock issuable upon the
conversion or exercise of options, warrants, rights or Convertible Securities
(whether or not then exercisable), and the number of shares of Common Stock
which the aggregate consideration for the total number of such additional shares
of Common Stock so issued would purchase at the Trigger Price Per Share. The
date as of which the Trigger Price Per Share shall be computed shall be the
earlier of the date on which the Company shall enter into a firm contract or
commitment for the issuance of such additional shares of Common Stock or the
date of actual issuance of such additional shares of Common Stock.

                  The provisions of this Section 6(a)(iii) shall not apply to
any issuance of additional shares of Common Stock for which an adjustment is
otherwise provided under Section 6(a)(i) hereof. No adjustment of the Aggregate
Number shall be made under this Section 6(a)(iii) upon the issuance of any
additional shares of Common Stock which are issued pursuant to (1) the exercise
of this Warrant in whole or in part or pursuant to any other Exempt Issuances,
(2) the exercise of other subscription or purchase rights or (3) the exercise of
any conversion or exchange rights in any Convertible Securities, provided that
for purposes of clauses (2) or (3) an adjustment shall previously have been made
upon the issuance of such other rights or upon the issuance of such Convertible
Securities (or upon the issuance of any warrants or other rights therefor)
pursuant to Section 6(a)(iv) hereof

                  (iv) CONVERTIBLE SECURITIES. If at any time or from time to
time the Company shall take a record of the holders of its Common Stock for the
purpose of entitling them to receive a distribution of, or shall in any manner
(whether directly, by assumption in a merger in which the Company is the
surviving corporation and in which the Stockholders of the Company immediately
prior to the merger continue to own more than 50% of the Outstanding Common
Stock immediately after the merger and for a period of 180 days thereafter, or
otherwise) issue or sell Convertible Securities (or any warrants or options or
other rights to subscribe for Convertible Securities), whether or not the rights
to subscribe, exchange or convert thereunder are immediately exercisable, and
the consideration per share for the additional shares of Common Stock which may
at any time thereafter be issuable pursuant to the terms of such Convertible
Securities (or any warrants or options or other rights to subscribe for
Convertible Securities) shall be less than the Trigger Price Per Share, then the
Aggregate Number shall be adjusted as provided in Section 6(a)(iii) hereof on
the basis that (A) the maximum number of additional shares of Common Stock
necessary to effect the conversion or exchange of all such Convertible
Securities or pursuant to all such warrants, options or other rights shall be
deemed to have been issued as of the date of the determination of the Trigger
Price Per Share as herein provided and (B) the aggregate consideration for such
maximum number of additional shares of Common Stock shall be deemed to be the
minimum consideration received and receivable by the Company for the issuance of
such additional shares of Common Stock pursuant to the terms of such Convertible
Securities (or any warrants or options or other rights to subscribe for
Convertible

                                       7

<Page>

Securities). For purposes of this Section 6(a)(iv), the effective date of such
adjustment and the date as of which the Trigger Price Per Share shall be
computed shall be the earliest of (1) the date on which the Company shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive any such Convertible Securities (or any warrants or options or other
rights to subscribe for Convertible Securities), (2) the date on which the
Company shall enter into a firm contract or commitment for the issuance of such
Convertible Securities (or any warrants or options or other rights to subscribe
for Convertible Securities) and (3) the date of actual issuance of such
Convertible Securities (or any warrants or options or other rights to subscribe
for Convertible Securities).

                  (v) SUBSEQUENT ADJUSTMENTS. If at any time after any
adjustment of the Aggregate Number shall have been made pursuant to Section
6(a)(iv) hereof on the basis of the issuance of warrants, options or other
rights or the issuance of Convertible Securities, or after any new adjustments
of the Aggregate Number shall have been made pursuant to this Section 6(a)(v),

                           (A) such warrants, options or rights or the right of
         conversion or exchange in such Convertible Securities shall expire, and
         a portion of such warrants, options or rights, or the right of
         conversion or exchange in respect of a portion of such Convertible
         Securities, as the case may be, shall not have been exercised prior to
         such expiration, and/or

                           (B) in the case of adjustments made pursuant to
         Section 6(a)(iv), the consideration per share for which shares of
         Common Stock are issuable pursuant to such warrants, options or rights
         per the terms of such Convertible Securities shall be irrevocably
         increased solely by virtue of provisions therein contained for an
         automatic increase in such consideration per share upon the arrival of
         a specified date or the happening of a specified event,

such previous adjustment shall be rescinded and annulled and the additional
shares of Common Stock which were deemed to have been issued by virtue of the
computation made in connection with such adjustment shall no longer be deemed to
have been issued by virtue of such computation. Simultaneously therewith, a
recomputation shall be made of the effect of such warrants, options or rights or
Convertible Securities on the determination of the Aggregate Number, which shall
be made on the basis of

                           (1) treating the number of additional shares of
                 Common Stock, if any, theretofore actually issued pursuant to
                 the previous exercise of such warrants, options or rights or
                 such right of conversion or exchange as having been issued on
                 the date or dates of such exercise and, in the case of a
                 recomputation of a calculation originally made pursuant to
                 Section 6(a)(iv), for the consideration actually received and
                 receivable therefor, and

                           (2) in the case of a recomputation of a calculation
                 originally made pursuant to Section 6(a)(iv), treating any such
                 warrants, options or rights or any such Convertible Securities
                 which then remain outstanding as having been granted

                                       8

<Page>

                  or issued immediately after the time of such irrevocable
                  increase of the consideration per share for which shares of
                  Common Stock are issuable under such warrants, options or
                  rights or Convertible Securities;

         and, if and to the extent called for by the foregoing provisions of
         this Section 6(a)(v) on the basis aforesaid, a new adjustment of the
         Aggregate Number shall be made, such new adjustment shall supersede the
         previous adjustment so rescinded and annulled.

                  (vi) MISCELLANEOUS. The following provisions shall be
applicable to the making of adjustments of the Aggregate Number provided above
in this Section 6(a):

                           (A) The sale or other disposition of any issued
         shares of Common Stock owned or held by or for the account of the
         Company or any of its Subsidiaries shall be deemed an issuance thereof
         for the purposes of this Section 6(a).

                           (B) To the extent that any additional shares of
         Common Stock or any Convertible Securities or any warrants, options or
         other rights to subscribe for or purchase any additional shares of
         Common Stock or any Convertible Securities (1) are issued solely for
         cash consideration, the consideration received by the Company therefor
         shall be deemed to be the amount of the cash received by the Company
         therefor, (2) are offered by the Company for subscription, the
         consideration received by the Company shall be deemed to be the
         subscription price or (3) are sold to underwriters or dealers for
         public offering, the net consideration (after giving effect to
         underwriting discounts) received by the Company shall be deemed to be
         the consideration received by the Company therefor, in any such case
         excluding any amounts paid or receivable for accrued interest or
         accrued dividends. To the extent that such issuance shall be for a
         consideration other than cash, or partially for cash and partially for
         other consideration, then, except as otherwise expressly provided
         herein, the amount of such consideration shall be deemed to be the fair
         market value of such consideration plus, if applicable, the amount of
         such cash) at the time of such issuance, determined in the manner set
         forth in Section 6(d)(ii). In case any additional shares of Common
         Stock or any Convertible Securities or any warrants, options or other
         rights to subscribe for or purchase such additional shares of Common
         Stock or Convertible Securities shall be issued in connection with any
         merger in which the Company is the survivor and issues any securities,
         the amount of consideration therefor shall be deemed to be the fair
         market value of such additional shares of Common Stock, Convertible
         Securities, warrants, options or other rights, as the case may be,
         determined in the manner set forth in Section 6(d)(ii).

                           The consideration for any shares of Common Stock
         issuable pursuant to the terms of any Convertible Securities shall be
         equal to (x) the consideration received by the Company for issuing any
         warrants, options or other rights to subscribe for or purchase such
         Convertible Securities, plus (y) the consideration paid or payable to
         the Company in respect of the subscription for or purchase of such
         Convertible Securities, plus (z) the consideration, if any, payable to
         the Company upon the exercise of the right of conversion or exchange of
         such Convertible Securities.

                                       9

                 In case of the issuance at any time of any additional shares of
Common Stock or Convertible Securities in payment or satisfaction of any
dividends upon any class of stock other than Common Stock, the Company shall be
deemed to have received for such additional shares of Common Stock or
Convertible Securities a consideration equal to the amount of such dividend so
paid or satisfied.

                           (C) The adjustments required by the preceding
         paragraphs of this Section 6(a) shall be made whenever and as often as
         any specified event requiring an adjustment shall occur, except that no
         adjustment of the Aggregate Number that would otherwise be required
         shall be made (except in the case of a Stock Subdivision or Stock
         Combination, as provided for in Section 6(a)(i) hereof) unless and
         until such adjustment either by itself or with other adjustments not
         previously made adds or subtracts at least one-tenth of one share to or
         from the Aggregate Number immediately prior to the making of such
         adjustment. Any adjustment representing a change of less than such
         minimum amount (except as aforesaid) shall be carried forward and made
         as soon as such adjustment, together with other adjustments required by
         this Section 6(a) and not previously made, would result in a minimum
         adjustment. For the purpose of any adjustment, any specified event
         shall be deemed to have occurred at the close of business on the date
         of its occurrence.

                           (D) In computing adjustments under this Section 6(a),
         fractional interests in Common Stock shall be taken into account to the
         nearest one-thousandth of a share.

                           (E) If the Company shall take a record of the holders
         of its Common Stock for the purpose of entitling them to receive a
         dividend or distribution or subscription or purchase rights and shall,
         thereafter and before the distribution to Stockholders thereof, legally
         abandon its plan to pay or deliver such dividend, distribution,
         subscription or purchase rights, then no adjustment shall be required
         by reason of the taking of such record and any such adjustment
         previously made in respect thereof shall be rescinded and annulled.

         (b) CHANGES IN COMMON STOCK. In case at any time the Company shall
initiate any transaction or be a party to any transaction with a Person other
than an Affiliate (including, without limitation, a merger, consolidation, share
exchange, sale, lease or other disposition of all or substantially all of the
Company's assets, liquidation, recapitalization or reclassification of the
Common Stock) in connection with which the previous Outstanding Common Stock
shall be changed into or exchanged for different securities of the Company or
capital stock or other securities of another corporation or interests in a
non-corporate entity or other property (including cash) or any combination of
the foregoing (each such transaction being herein called a "TRANSACTION"), then,
the Company shall use its commercially reasonable efforts in connection with the
consummation of the Transaction, to provide that lawful, enforceable and
adequate provision shall be made so that the Holder shall be entitled to receive
a new warrant in form and substance similar to, and in exchange for, this
Warrant to purchase all or a portion of such securities or other property;
provided, that, if the Company is unable to secure such new warrant, then the
Holder will exercise this Warrant in connection with the consummation of the

                                       10

<Page>

Transaction for, in lieu of the Warrant Shares issuable upon such exercise, the
securities or other property (including cash) to which such Holder would have
been entitled upon consummation of the Transaction if such Holder had exercised
this Warrant immediately prior thereto (subject to adjustments from and after
the consummation date as nearly equivalent as possible to the adjustments
provided for in this Section 6). The Company will use its commercially
reasonable efforts to have each corporation or other entity (other than the
Company) which may have agreed to deliver any new warrant, securities or other
property as provided herein assume, by written instrument delivered to the
Holder, the obligation to deliver to such Holder such new warrant, securities or
other property as in accordance with the foregoing provisions such Holder may be
entitled to receive and such corporation or entity shall have similarly
delivered to the Holder an opinion of counsel for such corporation or entity,
satisfactory to the Holder, which opinion shall state that all of the terms of
the new warrant or this Warrant shall be enforceable against the Company and
such corporation or entity in accordance with the terms hereof and thereof,
together with such other matters as the Holder may reasonably request. The
Company may cancel this Warrant if, in violation of the terms herein, the Holder
does not exercise this Warrant as required pursuant to this Section 6(b).

         (c) OTHER ACTION AFFECTING COMMON STOCK. In case at any time or from
time to time the Company shall take any action of the type contemplated in
Section 6(a) or (b) hereof but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights,
phantom stock rights or other rights with equity features), then, unless in the
opinion of the Company's board of directors such action will not have a material
adverse effect upon the rights of the Holder (taking into consideration, if
necessary, any prior actions which the Board of Directors deemed not to
materially adversely affect the rights of the Holder), the Aggregate Number
shall be adjusted in such manner and at such time as the Board of Directors of
the Company may in good faith determine to be equitable in the circumstances.

         (d) NOTICES.

                  (i) NOTICE OF PROPOSED ACTIONS. In case the Company shall
propose (A) to pay any dividend payable in stock of any class to the holders of
its Common Stock or to make any other distribution to the holders of its Common
Stock, (B) to offer to the holders of its Common Stock rights to subscribe for
or to purchase any Convertible Securities, rights to acquire Convertible
Securities or capital stock or additional shares of Common Stock or shares of
stock of any class or any other securities, warrants, rights or options, (C) to
effect any reclassification of its Common Stock, (D) to effect any
recapitalization, stock subdivision, stock combination or other capital
reorganization, (E) to effect any consolidation or merger, share exchange, or
sale, lease or other disposition of all or substantially all of its property,
assets or business, (F) to effect the liquidation, dissolution or winding up of
the Company or (G) to effect any other action which would require an adjustment
under this Section 6, then in each such case the Company shall give to the
Holder written notice of such proposed action, which shall specify the proposed
date on which a record is to be taken for the purposes of such stock dividend,
distribution or rights, or the proposed date on which such reclassification,
reorganization, consolidation, merger, share exchange, sale, transfer,
disposition, liquidation, dissolution, winding up or other transaction is to
take place and the date of participation therein by the holders of Common Stock,
if any such date is to be fixed, or the proposed date on which the

                                       11

<Page>

transfer of Common Stock is to occur, and shall also set forth such facts with
respect thereto as shall be reasonably necessary to indicate the effect of such
action on the Common Stock and on the Aggregate Number after giving effect to
any adjustment which will be required as a result of such action. Such notice
shall be so given in the case of any action covered by clause (A) or (B) above
at least 30 days prior to the record date for determining holders of the Common
Stock for purposes of such action and, in the case of any other such action, at
least 30 days prior to the earlier of the date of the taking of such proposed
action or the date of participation therein by the holders of Common Stock.

                 (ii) ADJUSTMENT NOTICE. Whenever the Aggregate Number is to be
adjusted pursuant to this Section 6, unless otherwise agreed by the Holder, the
Company shall promptly (and in any event within 10 Business Days after the event
requiring the adjustment) prepare a certificate signed by the chief financial
officer of the Company, setting forth, in reasonable detail, the event requiring
the adjustment and the method by which such adjustment is to be calculated. The
certificate shall set forth, if applicable, a description of the basis on which
the Board of Directors in good faith determined, as applicable, the Trigger
Price Per Share, the fair market value of any evidences of indebtedness, shares
of stock, other securities, warrants, other subscription or purchase rights, or
other property or the equitable nature of any adjustment under Section 6(b) or
(c) hereof, the new Aggregate Number and, if applicable, any new securities or
property to which the Holder is entitled. The Company shall promptly cause a
copy of such certificate to be delivered to the Holder. In the case of any
determination of Fair Market Value Per Share, such certificate shall be
delivered to the Holder within the time period set forth in the definition of
Fair Market Value Per Share and the Holder may object thereto as provided
therein. Any other determination of fair market value shall first be determined
in good faith by the Board of Directors and be based upon an arm's length sale
of such indebtedness, shares of stock, other securities, warrants, other
subscription or purchase rights or other property, such sale being between a
willing buyer and a willing seller. In the case of any such determination of
fair market value, the Holder may object to the determination in such
certificate by giving written notice within 10 Business Days of the receipt of
such certificate and, if the Holder and the Company cannot agree to the fair
market value within 10 Business Days of the date of the Holder's objection, the
fair market value shall be determined by a national or regional investment bank
or a national accounting firm mutually selected by the Holder and the Company,
the fees and expenses of which shall be paid 50% by the Company and 50% by the
Holder unless such determination results in a fair market value more than 110%
of the fair market value determined by the Company in which case such fees and
expenses shall be paid by the Company or results in a fair market value less
than 90% of the fair market value determined by the Company in which case such
fees and expenses shall be paid by the Holder. The Company shall keep at its
Principal Office copies of all such certificates and cause the same to be
available for inspection at said office during normal business hours by the
Holder or any prospective purchaser of the Warrant (in whole or in part) if so
designated by the Holder.

SECTION 7. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, share exchange, dissolution or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms of this Warrant, including without limitation the adjustments
required under Section 6 hereof, and will at all times in good faith

                                       12

<Page>

assist in the carrying out of all such terms and in taking of all such action as
may be necessary or appropriate to protect the rights of the Holder against
dilution or other impairment. Without limiting the generality of the foregoing
and notwithstanding any other provision of this Warrant to the contrary
(including by way of implication), the Company (a) will not increase the par
value of any shares of Common Stock receivable on the exercise of this Warrant
above the amount payable therefor on such exercise and (b) will take all such
action as may be necessary or appropriate so that the Company may validly and
legally issue fully paid and nonassessable shares of Common Stock upon the
exercise of this Warrant.

SECTION 8. TRANSFERS OF THE WARRANT.

         (a) GENERALLY. Subject to the restrictions set forth in this Section 8
and the Stockholders Agreement, the Holder may at any time and from time to time
freely transfer this Warrant and the Warrant Shares in whole or in part to any
Person. This Warrant has not been, and the Warrant Shares at the time of their
issuance may not be, registered under the Securities Act and except as provided
in the Registration Agreement or the Stockholders Agreement, nothing herein
contained shall be deemed to require the Company to so register this Warrant and
the Warrant Shares. This Warrant and the Warrant Shares are issued or issuable
subject to the provisions and conditions contained herein and in the Bridge Loan
Agreement and to the provisions and conditions contained in the Stockholders
Agreement and the Registration Agreement, and every Holder hereof by accepting
the same agrees with the Company to such provisions and conditions, and
represents to the Company that this Warrant has been acquired and the Warrant
Shares will be acquired for the account of the Holder for investment and not
with a view to or for sale in connection with any distribution thereof

         (b) COMPLIANCE WITH SECURITIES LAWS. The Holder agrees that this
Warrant and the Warrant Shares may not be sold or otherwise disposed of except
pursuant to an effective registration statement under the Securities Act and
applicable state securities laws or pursuant to an applicable exemption from the
registration requirements of the Securities Act and such state securities laws.
In the event that the Holder transfers this Warrant or the Warrant Shares
pursuant to an applicable exemption from registration, the Company may request,
at its expense, that the Holder deliver an opinion of counsel reasonably
acceptable to the Company that the proposed transfer does not violate the
Securities Act and applicable state securities laws.

         (c) RESTRICTIVE SECURITIES LEGEND. The certificate representing the
Warrant Shares shall bear the restrictive legends set forth below:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933, or the securities laws of any State
         and may not be sold or otherwise disposed of except pursuant to an
         effective registration statement under such Act and applicable State
         securities laws or pursuant to an applicable exemption from the
         registration requirements of such Act and such laws."

         "The shares represented by this certificate are subject to the terms
         and conditions, including certain transfer restrictions, of the
         Stockholders Agreement among the Company and certain of the Company's
         Stockholders. A copy of such agreement

                                       13

<Page>

         may be obtained at no cost by written request to the Company made by
         the holder of this certificate."

         (d) JOINDER. The Holder agrees that it will not transfer this Warrant
or the Warrant Shares unless the transferee thereof has agreed to become a party
to the Stockholder Agreement and the Registration Agreement and subject to all
the terms and conditions therein.

SECTION 9. COVENANTS.

         The Company hereby represents, warrants and covenants to the Holder
that so long as Holder holds the Warrant or any Warrant Shares:

         (a) LIMITATION ON CERTAIN RESTRICTIONS. The Company will not, and will
not permit or cause any of its Subsidiaries to, directly or indirectly, create
or otherwise cause or suffer to exist or become effective any restriction or
encumbrance (other than the Senior Credit Documents, the Bridge Loan Documents
and Rollover Investment Agreement) on the ability of the Company and any such
Subsidiaries to perform and comply with their respective obligations under this
Warrant.

         (b) TRANSACTIONS WITH AFFILIATES. The Company shall not, and shall not
permit any of its Subsidiaries to, directly or indirectly, (i) enter into, or be
a party to, any transaction with any of its Affiliates or (ii) in connection
with any transaction with any of its Affiliates, amend, modify or change any
provision of its articles or certificate of incorporation, bylaws, or the terms
of any class or series of its Capital Stock, except in each case pursuant to the
reasonable requirements of its business and which are on fair and reasonable
terms (and with respect to any transaction or series of transactions in excess
of $200,000, that are fully disclosed to the Required Holders) and which are no
less favorable to it than it would obtain in a comparable arm's length
transaction with a Person who is not an Affiliate. The Company shall not amend
the Professional Services Agreement to increase the remuneration, fees or
reimbursement of expenses payable thereunder or otherwise in each case in a way
that materially adversely affects the interests of the Purchaser or waive any
provisions thereof.

SECTION 10. EVENTS OF NON-COMPLIANCE AND REMEDIES.

         (a) EVENTS OF NON-COMPLIANCE. If the Company fails to keep and fully
and promptly perform and observe in all material respects any of the terms,
covenants or representations contained or referenced herein within 30 days from
the earlier to occur of (A) written notice from the Holder specifying what
failure has occurred, or requesting that a specified failure be remedied or (B)
an executive officer of the Company becoming aware of such failure (an "EVENT OF
NON-COMPLIANCE"), the Holder shall be entitled to the remedies set forth in
subsection (b) hereof.

         (b) REMEDIES. On the occurrence of an Event of Non-Compliance, in
addition to any remedies the Holder may have under applicable law, the Holder
may bring any action for injunctive relief or specific performance of any term
or covenant contained herein or in the

                                       14

SECTION 21. AMENDMENTS. Neither this Warrant nor any term hereof may be amended,

the Required Holders and the Company to such action.

SECTION 22. RULES OF CONSTRUCTION. Unless the context otherwise requires "or" is
not exclusive, and references to sections or subsections refer to sections or
subsections of this Warrant. All pronouns and any variations thereof refer to
the masculine, feminine or neuter, singular or plural, as the context may
require.

SECTION 23. PREEMPTIVE RIGHTS.

         (a) Except for Exempt Equity Issuances, if the Company authorizes the
issuance or sale of any shares of Common Stock, or any securities containing
options or rights to acquire any shares of Common Stock, the Company will, at
least 20 days prior to the issuance or sale, notify each holder of Warrant
Shares in writing of the price of and any material terms relating to the
proposed issuance or sale (to the extent then known). "EXEMPT EQUITY ISSUANCES"
means issuances of Common Stock or securities containing options or rights to
acquire shares of Common Stock (i) upon the conversion or exercise of any
securities of the Company (including, without limitation, the Preferred Stock)
or options, warrants or other rights to acquire securities of the Company
existing as of the date of the issuance of this Warrant or securities that the
Holder has had the right and the opportunity and passed on purchasing their Pro
Rata Portion pursuant to this Section 23, (ii) the issuance of shares of Common
Stock as consideration in connection with the acquisition of all or a
controlling interest in another business (whether by merger, purchase of stock
or assets or otherwise) if such issuance is approved by the Board of Directors,
(iii) pursuant to a bona fide underwritten public offering registered under the
Securities Act, (iv) as a dividend on the outstanding Common Stock, (v) to
directors, officers, employees, consultants or advisors of the Company or its
subsidiaries (other than the Sponsor and its Affiliates) pursuant to plans or
arrangements approved by the Board of Directors, (vi) to lenders and other
financial sources (other than the Sponsor and its Affiliates) in connection with
any borrowings, credit arrangements, equipment financings or similar
transactions that are approved by the Board of Directors, or (vii) in connection
with corporate partnering and strategic transactions (other than the Sponsor and
its Affiliates) involving the Company or its Subsidiaries as approved by the
Board of Directors.

         (b) Each holder of Warrant Shares may elect to purchase up to the Pro
Rata Portion of the securities to be issued in the issuance or sale at the same
price and on the terms identified in the notice. If all Persons entitled to
purchase or receive such stock or securities are required generally to also
purchase other securities of the Company, then each holder of Warrant Shares
shall also be required to purchase the same strip of securities (on the same
terms and conditions) that such other Persons are required to purchase. "PRO
RATA PORTION" means a percentage of the issuance or sale equal to the quotient
obtained by dividing (1) the aggregate number of shares of Common Stock
(including the number of shares of Common Stock issuable upon the exercise,
exchange or conversion of any option, warrant or exchangeable or Convertible
Securities) that are held by such Stockholder, by (2) the aggregate number of
shares of Common Stock

                                       22

<Page>

(including the number of shares of Common Stock issuable upon the exercise,
exchange or conversion of any option, warrant or exchangeable or Convertible
Securities) then outstanding.

         (c) The election of any holder of Warrant Shares must be made in
writing and delivered to the Company within 15 days after receipt by the holders
of Warrant Shares of the notice from the Company provided under this Section 23.
If after notifying such holders of Warrant Shares, the Company elects not to
proceed with the issuance or sale, any elections made by the holders of Warrant
Shares shall be deemed rescinded.

         (d) Upon the expiration of the offering periods described above, the
Company shall be entitled to sell such stock or securities which the holders of
Warrant Shares have not elected to purchase during the 120 days following such
expiration on terms and conditions no more favorable to the purchasers thereof
than those offered to the holders of Warrant Shares. Any stock or securities
offered or sold by the Company after such 120-day period must be re-offered to
the holders of Warrant Shares pursuant to the terms of this SECTION 23.

         (e) This SECTION 23 shall terminate upon the consummation of a
Qualified Public Offering.

                                       23

Stock to be sold in the contemplated Transfer. For purposes of this SECTION

     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).

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

Management Agreements, (viii) a Transfer of Stockholder Shares held by the

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

          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

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.

          11.  AMENDMENT AND WAIVER. Except as otherwise provided herein, no
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
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. Notwithstanding any
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
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.

          15.  COUNTERPARTS. This Agreement may be executed in separate
counterparts (including by means of telecopied signature pages), each of which

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
