          4.   PARTICIPATION RIGHTS.

          (a)  At least 30 days prior to any Transfer of Stockholder Shares
which are shares of Preferred Stock by the GTCR Investors, the GTCR Investors
shall deliver a written notice (the "PREFERRED SALE NOTICE") to the Company and
the other Stockholders (the "NON-GTCR STOCKHOLDERS") specifying in reasonable
detail the identity of the prospective transferee(s) and the terms and
conditions of the Transfer. The Non-GTCR Stockholders may elect to participate
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
Transfer, at the same price and on the same terms, a number of shares of
Preferred Stock equal to the product of (A) the quotient determined by dividing
the number of shares of Preferred Stock owned by such Person by the aggregate
number of outstanding shares of Preferred Stock owned by the GTCR Investors and
the Non-GTCR Stockholders participating in such sale and (B) the number of
shares of Preferred Stock to be sold in the contemplated Transfer.

                                        4
<Page>

          (b)  At least 30 days prior to any Transfer of Stockholder Shares
which are shares of Common Stock by the GTCR Investors, the Bajaj Group or the
Pearlstein Group (collectively, the "SUBJECT STOCKHOLDERS"), the Subject
Stockholder proposing to make such Transfer shall deliver a written notice (the
"COMMON SALE NOTICE") to the Company and the other Stockholders (collectively,
the "NON-SUBJECT STOCKHOLDERS") specifying in reasonable detail the identity of
the prospective transferee(s) and the terms and conditions of the Transfer. The
Non-Subject Stockholders may elect to participate in the contemplated Transfer
by delivering written notice to the Subject Stockholders within 30 days after
delivery of the Common Sale Notice. If any Non-Subject Stockholders have elected
to participate in such Transfer, the Subject Stockholders and such Non-Subject
Stockholders will be entitled to sell in the contemplated Transfer, at the same
price and on the same terms, a number of shares of Common Stock equal to the
product of (i) the quotient determined by dividing the number of shares of
Common Stock owned by such Person by the aggregate number of outstanding shares
of Common Stock owned by the Subject Stockholders and the Non-Subject
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
4(b), if a holder of shares of Class B Preferred elects to participate in the
contemplated Transfer, (x) the "number of shares of Common Stock owned" by such
holder shall equal the quotient determined by dividing (1) the aggregate
liquidation value of the shares of Class B Preferred then owned by such holder
(plus all accrued and unpaid dividends thereon), by (2) 81.667% of the
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
of shares of Common Stock owned by such holder as calculated pursuant to clause
(x) above.

          (c)

               (i)    The GTCR Investors will use commercially reasonable
     efforts to obtain the agreement of the prospective transferee(s) to the
     participation of the Non-GTCR Stockholders in any Transfer contemplated by
     Section 4(a), and the GTCR Investors will not transfer any of their
     Stockholder Shares to the prospective transferee(s) unless (A) the
     prospective transferee(s) agrees to allow the participation of the Non-GTCR
     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
     efforts to obtain the agreement of the prospective transferee(s) to the
     participation of the Non-Subject Stockholders in any Transfer contemplated
     by Section 4(b), and the Subject Stockholders will not transfer any of
     their Stockholder Shares to the prospective transferee(s) unless (A) the
     prospective transferee(s) agrees to allow the participation of the
     Non-Subject Stockholders at the same price and on the same terms, or (B)
     the Subject Stockholders agree to purchase the number of such class of
     Stockholder Shares from the Non-Subject Stockholders which the Non-Subject
     Stockholders would have been entitled to sell pursuant to SECTION 4(b) for
     the consideration per share to be paid to the Subject Stockholders by the
     prospective transferee(s).

                                        5

          (d)  Notwithstanding anything to the contrary in any other provision
of this Agreement, this SECTION 4 shall not apply with respect to (i) any
Transfer of Stockholder Shares by any GTCR Investor to or among its Affiliates,
(ii) an Exempt Bajaj Transfer, (iii) an Exempt Pearlstein Transfer, or (iv) a
Public Sale; 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) and (iii) and, as a condition to such Transfer, 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 clause (i), (ii) or (iii) 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. Notwithstanding the
foregoing, no party hereto shall avoid the provisions of this Agreement by
making one or more Transfers to one or more Affiliates and then disposing of all
or any portion of such party's interest in any such Affiliate.

          (e)  This Section 4 will terminate upon the first to occur of (i) the
consummation of an Approved Sale and (ii) the consummation of a Qualified Public
Offering.

          5.   FIRST REFUSAL RIGHTS.

          (a)  Prior to making any Transfer of Stockholder Shares, any
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.

          7.   VOTING REQUIREMENT.

          (a)  During the term of this Agreement and while the exemption
pursuant to Section 280G(b)(5)(A) of the Code is available, 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, and the Company shall take
all necessary and desirable actions within its control (including, without
limitation, calling a special stockholder meeting for such purpose, preparing
and distributing appropriate disclosure documents in connection therewith and
recommending that the Stockholders approve all proposals related thereto) to
approve any payment or benefit to be received by Bajaj or Pearlstein in
connection with a "change in ownership or control" (as such term is defined in
Section 280G of the Internal Revenue Code of 1986, as amended (the "CODE")), (a
"CHANGE OF CONTROL") of the Company or DigitalNet, under the Senior Management
Agreements, including, without limitation, any severance payment and the vesting
of any unvested securities of the Company (the "PAYMENT PROVISIONS").

          (b)  Promptly following the execution of this Agreement, (i) the
Company will prepare and distribute to the Stockholders a disclosure document
describing the Payment Provisions relating to Bajaj and Pearlstein in all
material respects and requesting the Stockholders' approval thereof (the "2001
CONSENT REQUEST") and (ii) the Stockholders agree to vote in favor of, or
consent to, the 2001 Consent Request.

          (c)  The Company shall condition the issuance of any of the voting
securities of the Company (including, without limitation, any voting securities

          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;

     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.

<Page>

          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.
