     SECTION 3. REGISTERED EXCHANGE OFFER.

     (a) Unless the Exchange Offer shall not be permissible under applicable law
or Commission policy (after the procedures set forth in Section 6(a) below have
been complied with), DigitalNet Holdings, the Company and the Subsidiary
Guarantor shall (i) use commercially reasonable best efforts to cause to be
filed with the Commission as soon as practicable after the Closing Date, but in
no event later than 90 days after the Closing Date, a Registration Statement
under the Securities Act relating to the Exchange Notes and the Exchange Offer,
(ii) use their commercially reasonable best efforts to cause such Registration
Statement to become effective at the earliest possible time, but in no event
later than 180 days after the Closing Date, (iii) in connection with the
foregoing, file (A) all pre-effective amendments to

                                        3
<Page>

such Registration Statement as may be necessary in order to cause such
Registration Statement to become effective, (B) if applicable, a post-effective
amendment to such Registration Statement pursuant to Rule 430A under the
Securities Act and (C) cause all necessary filings in connection with the
registration and qualification of the Exchange Notes to be made under the Blue
Sky laws of such jurisdictions as are necessary to permit Consummation of the
Exchange Offer, and (iv) upon the effectiveness of such Registration Statement,
commence the Exchange Offer. The Exchange Offer shall be on the appropriate form
permitting registration of the Exchange Notes to be offered in exchange for the
Transfer Restricted Securities and to permit resales of Notes held by
Broker-Dealers as contemplated by Section 3(c) below.

     (b) DigitalNet Holdings, the Company and the Subsidiary Guarantor shall
cause the Exchange Offer Registration Statement to be effective continuously and
shall keep the Exchange Offer open for a period of not less than the minimum
period required under applicable federal and state securities laws to Consummate
the Exchange Offer; PROVIDED, HOWEVER, that in no event shall such period be
less than 20 days after the date notice of the Exchange Offer is mailed to the
Holders. DigitalNet Holdings, the Company and the Subsidiary Guarantor shall
cause the Exchange Offer to comply with all applicable federal and state
securities laws. No securities other than the Notes shall be included in the
Exchange Offer Registration Statement. DigitalNet Holdings, the Company and the
Subsidiary Guarantor shall use their best efforts to cause the Exchange Offer to
be Consummated on the earliest practicable date after the Exchange Offer
Registration Statement has become effective, but in no event later than 40
business days after the Effectiveness Target Date with respect to the Exchange
Offer Registration Statement.

     (c) The Company shall indicate in a "Plan of Distribution" section
contained in the Prospectus forming a part of the Exchange Offer Registration
Statement that any Broker-Dealer who holds Initial Notes that are Transfer
Restricted Securities and that were acquired for its own account as a result of
market-making activities or other trading activities (other than Transfer
Restricted Securities acquired directly from the Company), may exchange such
Initial Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be
deemed to be an "underwriter" within the meaning of the Securities Act and must,
therefore, deliver a prospectus meeting the requirements of the Securities Act
in connection with any resales of the Exchange Notes received by such
Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may
be satisfied by the delivery by such Broker-Dealer of the Prospectus contained
in the Exchange Offer Registration Statement. Such "Plan of Distribution"
section shall also contain all other information with respect to such resales by
Broker-Dealers that the Commission may require in order to permit such resales
pursuant thereto, but such "Plan of Distribution" shall not name any such
Broker-Dealer or disclose the amount of Notes held by any such Broker-Dealer
except to the extent required by applicable law, regulation or the Commission as
a result of a change in policy after the date of this Agreement.

     Upon the request of an Initial Purchaser or a Broker-Dealer that receives
Exchange Notes for its own account in the Exchange Offer in exchange for
securities that were acquired by such Broker-Dealer as a result of market-making
or other trading activities (each such Initial Purchaser or Broker-Dealer, a
"Participating Broker-Dealer"), in order to expedite or facilitate the
disposition of Exchange Notes by Participating Broker-Dealers, DigitalNet
Holdings, the Company and the Subsidiary Guarantor shall use their commercially
reasonable best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented and

                                        4
<Page>

amended as required by the provisions of Section 6(c) below to the extent
necessary to ensure that it is available for resales of Notes acquired by
Participating Broker-Dealers, and to ensure that it conforms with the
requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period
ending on the earlier of (i) 180 days from the date on which the Exchange Offer
Registration Statement is declared effective and (ii) the date on which a
Participating Broker-Dealer is no longer required to deliver a prospectus in
connection with market-making or other trading activities.

     The Company shall provide sufficient copies of the latest version of such
Prospectus to Broker-Dealers promptly upon request at any time during such
180-day (or shorter as provided in the foregoing sentence) period in order to
facilitate such resales.

     SECTION 4. SHELF REGISTRATION.

     (a) SHELF REGISTRATION. If (i) DigitalNet Holdings, the Company and the
Subsidiary Guarantor are not required to file an Exchange Offer Registration
Statement or to consummate the Exchange Offer because the Exchange Offer is not
permitted by applicable law or Commission policy (after the procedures set forth
in Section 6(a) below have been complied with), (ii) for any reason the Exchange
Offer is not Consummated within 40 business days after the Effectiveness Target
Date with respect to the Exchange Offer Registration Statement, or (iii) any
Holder of Transfer Restricted Securities shall notify the Company prior to the
20th day following the Consummation of the Exchange Offer that (A) such Holder
is prohibited by applicable law or Commission policy from participating in the
Exchange Offer, or (B) such Holder may not resell the Exchange Notes acquired by
it in the Exchange Offer to the public without delivering a prospectus and that
the Prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such Holder, or (C) such Holder is
a Broker-Dealer and holds Initial Notes acquired directly from the Company, or
one of its affiliates, then, upon such Holder's request, DigitalNet Holdings,
the Company and the Subsidiary Guarantor shall

          (x) cause to be filed a shelf registration statement pursuant to Rule
     415 under the Securities Act, which may be an amendment to the Exchange
     Offer Registration Statement (in either event, the "Shelf Registration
     Statement") on or prior to the earliest to occur of (1) the 90th day after
     the date on which the Company determines that it is not required to file
     the Exchange Offer Registration Statement, (2) if the Exchange Offer is not
     Consummated within 40 business days after the Effectiveness Target Date for
     the Exchange Offer Registration Statement, the 90th day after such 40th day
     and (3) the 90th day after the date on which the Company receives notice
     from a Holder of Transfer Restricted Securities as contemplated by clause
     (iii) above, (such earlier date being the "Shelf Filing Deadline"), which
     Shelf Registration Statement shall provide for resales of all Transfer
     Restricted Securities the Holders of which shall have provided the
     information required pursuant to Section 4(b) hereof; and

          (y) use their commercially reasonable best efforts to cause such Shelf
     Registration Statement to be declared effective by the Commission on or
     before the 180th day after the obligation to file such Shelf Registration
     Statement arises.

                                        5
<Page>

     DigitalNet Holdings, the Company and the Subsidiary Guarantor shall use
their commercially reasonable best efforts to keep such Shelf Registration
Statement continuously effective, supplemented and amended as required by the
provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure
that it is available for resales of Notes by the Holders of Transfer Restricted
Securities entitled to the benefit of this Section 4(a), and to ensure that it
conforms with the requirements of this Agreement, the Securities Act and the
policies, rules and regulations of the Commission as announced from time to
time, for a period of at least two years following the effective date of such
Shelf Registration Statement (or shorter period that will terminate when all the
Notes covered by such Shelf Registration Statement have been sold pursuant to
such Shelf Registration Statement).

     (b) PROVISION BY HOLDERS OF CERTAIN INFORMATION IN CONNECTION WITH THE
SHELF REGISTRATION STATEMENT. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. Each Holder as to which any Shelf Registration
Statement is being effected agrees to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

     SECTION 5. ADDITIONAL INTEREST. If (i) any of the Registration Statements
required by this Agreement is not filed with the Commission on or prior to the
date specified for such filing in this Agreement, (ii) any of such Registration
Statements has not been declared effective by the Commission on or prior to the
date specified for such effectiveness in this Agreement (the "Effectiveness
Target Date"), (iii) the Exchange Offer has not been Consummated within 40
business days after the Effectiveness Target Date with respect to the Exchange
Offer Registration Statement or (iv) any Registration Statement required by this
Agreement is filed and declared effective but shall thereafter cease to be
effective or fail to be usable for its intended purpose without being succeeded
immediately by a post-effective amendment to such Registration Statement that
cures such failure and that is itself immediately declared effective (each such
event referred to in clauses (i) through (iv), a "Registration Default"),
DigitalNet Holdings, the Company and the Subsidiary Guarantor hereby agree
jointly and severally that they will pay Liquidated Damages to each Holder of
Transfer Restricted Securities, with respect to the first 90-day period
immediately following the occurrence of any Registration Default in an amount
equal to $0.05 per week per $1,000 principal amount of Transfer Restricted
Securities held by such Holder. The amount of the Liquidated Damages will
increase by an additional $0.05 per week per $1,000 principal amount of such
Transfer Restricted Securities with respect to each subsequent 90-day period
until all Registration Defaults have been cured, up to a maximum amount of
Liquidated Damages for all Registration Defaults of $0.385 per week per $1,000
principal amount of such Transfer Restricted Securities. Following the cure of
all Registration Defaults relating to any particular Transfer Restricted
Securities, the accrual of Liquidated Damages will cease and the interest rate
borne by the relevant Transfer Restricted Securities shall be reduced to the
original interest rate borne by such Transfer Restricted Securities; provided,
however, that, if after any such cure, a different Registration Default occurs,
the Liquidated Damages shall again accrue pursuant to the foregoing provisions.

                                        6
<Page>

     All obligations of DigitalNet Holdings, the Company and the Subsidiary
Guarantor set forth in the preceding paragraph that are outstanding with respect
to any Transfer Restricted Security at the time such security ceases to be a
Transfer Restricted Security shall survive until such time as all such
obligations with respect to such Note shall have been satisfied in full.

     SECTION 6. REGISTRATION PROCEDURES.

     (a) EXCHANGE OFFER REGISTRATION STATEMENT. In connection with the Exchange
Offer, DigitalNet Holdings, the Company and the Subsidiary Guarantor shall
comply with all of the provisions of Section 6(c) below, shall use their best
efforts to effect such exchange to permit the sale of Transfer Restricted
Securities being sold in accordance with the intended method or methods of
distribution thereof, and shall comply with all of the following provisions:

          (i)     If in the reasonable opinion of counsel to the Company there
     is a question as to whether the Exchange Offer is permitted by applicable
     law, DigitalNet Holdings, the Company and the Subsidiary Guarantor hereby
     agree to seek a no-action letter or other favorable decision from the
     Commission allowing DigitalNet Holdings, the Company and the Subsidiary
     Guarantor to Consummate an Exchange Offer for such Initial Notes.
     DigitalNet Holdings, the Company and the Subsidiary Guarantor each hereby
     agrees to pursue the issuance of such a decision to the Commission staff
     level but shall not be required to take commercially unreasonable action to
     effect a change of Commission policy. DigitalNet Holdings, the Company and
     the Subsidiary Guarantor each hereby agrees, however, to (A) participate in
     telephonic conferences with the Commission, (B) deliver to the Commission
     staff an analysis prepared by counsel to the Company setting forth the
     legal bases, if any, upon which such counsel has concluded that such an
     Exchange Offer should be permitted and (C) diligently pursue a favorable
     resolution by the Commission staff of such submission.

          (ii)    As a condition to its participation in the Exchange Offer
     pursuant to the terms of this Agreement, each Holder of Transfer Restricted
     Securities shall furnish, upon the request of the Company, prior to the
     Consummation thereof, a written representation to the Company (which may be
     contained in the letter of transmittal contemplated by the Exchange Offer
     Registration Statement) to the effect that (A) it is not an affiliate of
     the Company, (B) it is not engaged in, and does not intend to engage in,
     and has no arrangement or understanding with any person to participate in,
     a distribution of the Exchange Notes to be issued in the Exchange Offer and
     (C) it is acquiring the Exchange Notes in its ordinary course of business.
     In addition, all such Holders of Transfer Restricted Securities shall
     otherwise cooperate in the Company's preparations for the Exchange Offer.
     Each Holder hereby acknowledges and agrees that any Broker-Dealer and any
     such Holder using the Exchange Offer to participate in a distribution of
     the securities to be acquired in the Exchange Offer (1) could not under
     Commission policy as in effect on the date of this Agreement rely on the
     position of the Commission enunciated in Morgan Stanley and Co., Inc.
     (available June 5, 1991) and Exxon Capital Holdings Corporation (available
     May 13, 1988), as interpreted in the Commission's letter to Shearman &
     Sterling dated July 2, 1993, and similar no-action letters (which may
     include any no-action letter obtained pursuant to clause (i) above), and
     (2) must comply with the registration and prospectus delivery requirements
     of the Securities Act in connection with

                                        7
<Page>

     a secondary resale transaction and that such a secondary resale transaction
     should be covered by an effective registration statement containing the
     selling security holder information required by Item 507 or 508, as
     applicable, of Regulation S-K if the resales are of Exchange Notes obtained
     by such Holder in exchange for Initial Notes acquired by such Holder
     directly from the Company.

     (b) SHELF REGISTRATION STATEMENT. In connection with the Shelf Registration
Statement, DigitalNet Holdings, the Company and the Subsidiary Guarantor shall
comply with all the provisions of Section 6(c) below and shall use their
commercially reasonable best efforts to effect such registration to permit the
sale of the Transfer Restricted Securities being sold in accordance with the
intended method or methods of distribution thereof, and pursuant thereto
DigitalNet Holdings, the Company and the Subsidiary Guarantor will use
commercially reasonable best efforts to promptly prepare and file with the
Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the
sale of the Transfer Restricted Securities in accordance with the intended
method or methods of distribution thereof.

     (c) GENERAL PROVISIONS. In connection with any Registration Statement and
any Prospectus required by this Agreement to permit the sale or resale of
Transfer Restricted Securities (including, without limitation, any Registration
Statement and the related Prospectus required to permit resales of Notes by
Broker-Dealers), DigitalNet Holdings, the Company and the Subsidiary Guarantor
shall:

          (i)     use their commercially reasonable best efforts to keep such
     Registration Statement continuously effective and provide all requisite
     financial statements (including, if required by the Securities Act or any
     regulation thereunder, financial statements of DigitalNet Holdings or the
     Subsidiary Guarantor for the period specified in Section 3 or 4 of this
     Agreement, as applicable; upon the occurrence of any event that would cause
     any such Registration Statement or the Prospectus contained therein (A) to
     contain a material misstatement or omission or (B) not to be effective and
     usable for resale of Transfer Restricted Securities during the period
     required by this Agreement, DigitalNet Holdings, the Company and the
     Subsidiary Guarantor shall file promptly an appropriate amendment to such
     Registration Statement, in the case of clause (A), correcting any such
     misstatement or omission, and, in the case of either clause (A) or (B), use
     its commercially reasonable best efforts to cause such amendment to be
     declared effective and such Registration Statement and the related
     Prospectus to become usable for their intended purpose(s) as soon as
     practicable thereafter;

          (ii)    prepare and file with the Commission such amendments and
     post-effective amendments to the Registration Statement as may be necessary
     to keep the Registration Statement effective for the applicable period set
     forth in Section 3 or 4 hereof, as applicable, or such shorter period as
     will terminate when all Transfer Restricted Securities covered by such
     Registration Statement have been sold; cause the Prospectus to be
     supplemented by any required Prospectus supplement, and as so supplemented
     to be filed pursuant to Rule 424 under the Securities Act, and to comply
     fully with the applicable provisions of Rules 424 and 430A under the
     Securities Act in a timely manner; and comply with the provisions of the
     Securities Act with respect to the disposition of all

                                        8
<Page>

     securities covered by such Registration Statement during the applicable
     period in accordance with the intended method or methods of distribution by
     the sellers thereof set forth in such Registration Statement or supplement
     to the Prospectus;

          (iii)   advise the underwriter(s), if any, and selling Holders
     promptly and, if requested by such Persons, to confirm such advice in
     writing, (A) when the Prospectus or any Prospectus supplement or
     post-effective amendment has been filed, and, with respect to any
     Registration Statement or any post-effective amendment thereto, when the
     same has become effective, (B) of any request by the Commission for
     amendments to the Registration Statement or amendments or supplements to
     the Prospectus or for additional information relating thereto, (C) of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement under the Securities Act or of the suspension
     by any state securities commission of the qualification of the Transfer
     Restricted Securities for offering or sale in any jurisdiction, or the
     initiation of any proceeding for any of the preceding purposes, (D) of the
     existence of any fact or the happening of any event that makes any
     statement of a material fact made in the Registration Statement, the
     Prospectus, any amendment or supplement thereto, or any document
     incorporated by reference therein untrue, or that requires the making of
     any additions to or changes in the Registration Statement or the Prospectus
     in order to make the statements therein not misleading. If at any time the
     Commission shall issue any stop order suspending the effectiveness of the
     Registration Statement, or any state securities commission or other
     regulatory authority shall issue an order suspending the qualification or
     exemption from qualification of the Transfer Restricted Securities under
     state securities or Blue Sky laws, DigitalNet Holdings, the Company and the
     Subsidiary Guarantor shall use their best efforts to obtain the withdrawal
     or lifting of such order at the earliest possible time;

          (iv)    in the case of a Shelf Registration, furnish without charge to
     each of the Initial Purchasers, each selling Holder named in any
     Registration Statement, and each of the underwriter(s), if any, before
     filing with the Commission, copies of any Registration Statement or any
     Prospectus included therein or any amendments or supplements to any such
     Registration Statement or Prospectus (including all documents incorporated
     by reference after the initial filing of such Registration Statement),
     which documents will be subject to the review of such Holders and
     underwriter(s) in connection with such sale, if any, for a period of at
     least five business days, and the Company will not file any such
     Registration Statement or Prospectus or any amendment or supplement to any
     such Registration Statement or Prospectus (including all such documents
     incorporated by reference) to which an Initial Purchaser of Transfer

     made upon confirmation of telecopy transmission within such period). The
     objection of an Initial Purchaser or underwriter, if any, shall be deemed
     to be reasonable if such Registration Statement, amendment, Prospectus or

     misstatement or omission;

     pursuant to such Registration Statement and any attorney or accountant

     rated with the appropriate rating agencies, if so requested by the Holders
     of a majority in aggregate principal amount of Notes covered thereby or the
     underwriter(s), if any;

          (ix)    furnish to each selling Holder and each of the underwriter(s),
     if any, without charge, at least one copy of the Registration Statement, as
     first filed with the Commission, and of each amendment thereto, including
     financial statements and schedules, all documents incorporated by reference

     amendment or supplement thereto;

          (xi)    enter into such agreements (including an underwriting
     agreement), and make such commercially reasonable representations and
     warranties, and take all such other commercially reasonable actions in
     connection therewith in order to expedite or facilitate the disposition of

     any Registration Statement contemplated by this Agreement; and whether or
     not an underwriting agreement is entered into and whether or not the
     registration is an Underwritten Registration, DigitalNet Holdings, the
     Company and the Subsidiary Guarantor shall:

                      (A) furnish to each Initial Purchaser, each selling Holder
          and each underwriter with respect to an Underwritten Offering pursuant
          to a Shelf Registration Statement in such substance and scope as they

                      of the Shelf Registration Statement, as the case may be,
                      signed by (y) the President or any Vice President and (z)
                      a principal financial or accounting officer of each of

                      Guarantor, confirming, as of the date thereof, the matters
                      set forth in paragraphs (i), (ii) and (iii) of Section 5
                      (e) of the Purchase Agreement and such other matters as
                      such parties may reasonably request;

                            (2) an opinion, dated the date of effectiveness of
                      the Shelf Registration Statement, as the case may be, of
                      counsel for DigitalNet Holdings, the Company and the
                      Subsidiary Guarantor, covering the matters set forth in
                      paragraph (c) of Section 5 of the Purchase Agreement and
                      such other matter as such parties may reasonably request,
                      and in any event including a statement that, in the course
                      of the preparation by the Company and the Guarantors of
                      the Registration Statement and the Prospectus, they have
                      participated in conferences with certain of the officers
                      and representatives of, and the independent public
                      accountants for, DigitalNet Holdings and its subsidiaries,
                      at which the Registration Statement and the Prospectus
                      were discussed. Such counsel shall also state that between
                      the date of effectiveness of the Registration Statement
                      and the time of delivery of this letter, they have held
                      additional conferences with certain of the officers and
                      representatives of, and the independent public accountants
                      for, the Company, at which the contents of the Prospectus
                      were discussed to a limited extent. Such counsel shall
                      state that given the limitations inherent in the
                      independent verification of factual matters and the
                      character of determinations involved in the registration
                      process, (except as expressly set forth in their opinion)
                      they

                                       11

                      are not passing upon or assuming any responsibility for
                      the accuracy, completeness or fairness of the statements
                      contained in the Registration Statement or the Prospectus
                      and have made no independent check or verification
                      thereof. Such counsel shall also state that subject to the
                      foregoing and on the basis of the information gained in
                      the performance of the services referred to above,
                      including information obtained from officers and other
                      representatives of, and the independent public accountants
                      for, the DigitalNet Holdings, no facts have come to such
                      counsel's attention that have caused them to believe that
                      the Registration Statement and the Prospectus included
                      therein, as of its effective date, contained any untrue
                      statement of a material fact or omitted to state a
                      material fact required to be stated therein or necessary
                      in order to make the statements therein not misleading or
                      that the Prospectus, as of its date, contained any untrue
                      statement of a material fact or omitted to state a
                      material fact necessary in order to make the statements
                      therein, in light of the circumstances under which they
                      were made, not misleading. Such counsel shall also state
                      that in each case, however, they expresses no view or
                      belief with respect to financial statements, notes or
                      schedules thereto or other financial or statistical data
                      included in or omitted from the Registration Statement or
                      Prospectus; and

                            (3) a customary comfort letter, dated as of the date
                      of effectiveness of the Shelf Registration Statement, as
                      the case may be, from DigitalNet Holdings' or the
                      Company's independent accountants, in the customary form
                      and covering matters of the type customarily covered in
                      comfort letters by underwriters in connection with primary
                      underwritten offerings, and affirming the matters set
                      forth in the comfort letters delivered pursuant to Section
                      5(a) of the Purchase Agreement, without exception;

                      (B) set forth in full or incorporate by reference in the
          underwriting agreement, if any, the indemnification provisions and
          procedures of Section 8 hereof with respect to all parties to be
          indemnified pursuant to said Section; and

                      (C) deliver such other documents and certificates as may
          be reasonably requested by such parties to evidence compliance with
          clause (A) above and with any customary conditions contained in the
          underwriting agreement or other agreement entered into by DigitalNet
          Holdings, the Company or the Subsidiary Guarantor pursuant to this
          clause (xi), if any.

          If at any time the representations and warranties of DigitalNet
     Holdings, the Company and the Subsidiary Guarantor contemplated in clause
     (A)(1) above cease to be true and correct, DigitalNet Holdings, the Company
     or such Subsidiary Guarantor shall so advise the Initial Purchasers and the
     underwriter(s), if any, and each selling Holder promptly and, if requested
     by such Persons, shall confirm such advice in writing;

                                       12

          (xii)   prior to any public offering of Transfer Restricted
     Securities, cooperate with the selling Holders, the underwriter(s), if any,
     and their respective counsel in connection with the registration and
     qualification of the Transfer Restricted Securities under the securities or
     Blue Sky laws of such jurisdictions as the selling Holders or
     underwriter(s) may request and do any and all other acts or things
     necessary or advisable to enable the disposition in such jurisdictions of
     the Transfer Restricted Securities covered by the Shelf Registration
     Statement; PROVIDED, HOWEVER, that none of DigitalNet Holdings, the Company
     nor the Subsidiary Guarantor shall be required to register or qualify as a
     foreign corporation where it is not then so qualified or to take any action
     that would subject it to the service of process in suits or to taxation,
     other than as to matters and transactions relating to the Registration
     Statement, in any jurisdiction where it is not then so subject;

          (xiii)  shall issue, upon the request of any Holder of Initial Notes
     covered by the Shelf Registration Statement, Exchange Notes, having an
     aggregate principal amount equal to the aggregate principal amount of
     Initial Notes surrendered to the Company by such Holder in exchange
     therefor or being sold by such Holder; such Exchange Notes to be registered
     in the name of such Holder or in the name of the purchaser(s) of such
     Notes, as the case may be; in return, the Initial Notes held by such Holder
     shall be surrendered to the Company for cancellation;

          (xiv)   cooperate with the selling Holders and the underwriter(s), if
     any, to facilitate the timely preparation and delivery of certificates
     representing Transfer Restricted Securities to be sold and not bearing any
     restrictive legends; and enable such Transfer Restricted Securities to be
     in such denominations and registered in such names as the Holders or the
     underwriter(s), if any, may request at least two business days prior to any
     sale of Transfer Restricted Securities made by such underwriter(s);

          (xv)    use their commercially reasonable best efforts to cause the
     Transfer Restricted Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof or
     the underwriter(s), if any, to consummate the disposition of such Transfer
     Restricted Securities, subject to the proviso contained in clause (viii)
     above;

          (xvi)   if any fact or event contemplated by clause (c)(iii)(D) above
     shall exist or have occurred, prepare a supplement or post-effective
     amendment to the Registration Statement or related Prospectus or any
     document incorporated therein by reference or file any other required
     document so that, as thereafter delivered to the purchasers of Transfer
     Restricted Securities, the Prospectus will not contain an untrue statement
     of a material fact or omit to state any material fact necessary to make the
     statements therein not misleading;

          (xvii)  provide a CUSIP number for all Transfer Restricted Securities
     not later than the effective date of the Registration Statement and provide
     the Trustee under the Indenture with printed certificates for the Transfer
     Restricted Securities which are in a form eligible for deposit with the
     Depositary Trust Company;

                                       13
<Page>

          (xviii) reasonably cooperate and assist in any filings required to be
     made with the NASD and in the performance of any due diligence
     investigation by any underwriter (including any "qualified independent
     underwriter") that is required to be retained in accordance with the rules
     and regulations of the NASD, and use its reasonable best efforts to cause
     such Registration Statement to become effective and approved by such
     governmental agencies or authorities as may be necessary to enable the
     Holders selling Transfer Restricted Securities to consummate the
     disposition of such Transfer Restricted Securities;

          (xix)   otherwise use their commercially reasonable best efforts to
     comply with all applicable rules and regulations of the Commission, and
     make generally available to the Company's security holders, as soon as
     practicable, a consolidated earnings statement meeting the requirements of
     Rule 158 (which need not be audited) for the twelve-month period (A)
     commencing at the end of any fiscal quarter in which Transfer Restricted
     Securities are sold to underwriters in a firm or best efforts Underwritten
     Offering or (B) if not sold to underwriters in such an offering, beginning
     with the first month of the Company's first fiscal quarter commencing after
     the effective date of the Registration Statement;

          (xx)    cause the Indenture to be qualified under the Trust Indenture
     Act not later than the effective date of the first Registration Statement
     required by this Agreement, and, in connection therewith, cooperate with
     the Trustee and the Holders of Notes to effect such changes to the
     Indenture as may be required for such Indenture to be so qualified in
     accordance with the terms of the Trust Indenture Act; and to execute, and
     cause each Guarantor to execute all documents that may be required to
     effect such changes and all other forms and documents required to be filed
     with the Commission to enable such Indenture to be so qualified in a timely
     manner; and

          (xxi)   cause all Transfer Restricted Securities covered by the
     Registration Statement to be listed on each securities exchange on which
     similar securities issued by the Company are then listed if requested by
     the Holders of a majority in aggregate principal amount of Initial Notes or
     the managing underwriter(s), if any.

     Each Holder agrees by acquisition of a Transfer Restricted Security that,
upon receipt of any notice from the Company of the existence of any fact of the
kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith
discontinue disposition of Transfer Restricted Securities pursuant to the
applicable Registration Statement until such Holder's receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 6(c)(xvi) hereof,
or until it is advised in writing (the "Advice") by the Company that the use of
the Prospectus may be resumed, and has received copies of any additional or
supplemental filings that are incorporated by reference in the Prospectus. If so
directed by the Company, each Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of such notice. In the event
the Company shall give any such notice, the time period regarding the
effectiveness of such Registration Statement set forth in Section 3 or 4 hereof,
as applicable, shall be extended by the number of days during the period from
and including the date of the giving of such notice pursuant to Section
6(c)(iii)(D) hereof to

                                       14
<Page>

and including the date when each selling Holder covered by such Registration
Statement shall have received the copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(xvi) hereof or shall have received the
Advice; however, no such extension shall be taken into account in determining
whether Additional Interest is due pursuant to Section 5 hereof or the amount of
such Additional Interest, it being agreed that the Company's option to suspend
use of a Registration Statement pursuant to this paragraph shall be treated as a
Registration Default for purposes of Section 5.

     SECTION 7.  REGISTRATION EXPENSES.

     (a) All expenses incident to Digital Holdings', the Company's or the
Subsidiary Guarantor' performance of or compliance with this Agreement will be

     SECTION 8.  INDEMNIFICATION.

                                       15
<Page>

     (a) DigitalNet Holdings, the Company and the Subsidiary Guarantor, jointly
and severally, agree to indemnify and hold harmless (i) each Holder and (ii)
each person, if any, who controls (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) any Holder (any of the persons
referred to in this clause (ii) being hereinafter referred to as a "controlling
person") and (iii) the respective officers, directors, partners, employees,
representatives and agents of any Holder or any controlling person (any person
referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an
"Indemnified Holder"), to the fullest extent lawful, from and against any and
all losses, claims, damages, liabilities, judgments, actions and expenses
(including without limitation and as incurred, reimbursement of all reasonable
costs of investigating, preparing, pursuing, settling, compromising, paying or
defending any claim or action, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, including the reasonable
fees and expenses of counsel to any Indemnified Holder), joint or several,
directly or indirectly caused by, related to, based upon, arising out of or in
connection with any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement or Prospectus (or any amendment or
supplement thereto), or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages,
liabilities or expenses are caused by an untrue statement or omission or alleged
untrue statement or omission that is made in reliance upon and in conformity
with information relating to any of the Holders furnished in writing to the
Company by any of the Holders expressly for use therein. This indemnity
agreement shall be in addition to any liability which the Company and the
Guarantors may otherwise have.

     In case any action or proceeding (including any governmental or regulatory
investigation or proceeding) shall be brought or asserted against any of the
Indemnified Holders with respect to which indemnity may be sought against
DigitalNet Holdings, the Company or the Subsidiary Guarantor, such Indemnified
Holder (or the Indemnified Holder controlled by such controlling person) shall
promptly notify the Company in writing (PROVIDED, that the omission so to notify
the Company (i) will not relieve DigitalNet Holdings, the Company or DGS from
any liability which it may have to any Indemnified Holder under paragraph (a)
above to the extent it is not materially prejudiced through the forfeiture of
substantial rights or defenses as a proximate result of such failure and (ii)
will not, in any event, release the indemnifying party from its other
obligations pursuant to this Agreement). Such Indemnified Holder shall have the
right to employ its own counsel in any such action and the fees and expenses of
such counsel shall be paid, as incurred, by DigitalNet Holdings, the Company and
the Subsidiary Guarantor (regardless of whether it is ultimately determined that
an Indemnified Holder is not entitled to indemnification hereunder). None of
DigitalNet Holdings, the Company or the Subsidiary Guarantor shall, in
connection with any one such action or proceeding or separate but substantially
similar or related actions or proceedings in the same jurisdiction arising out
of the same general allegations or circumstances, be liable for the reasonable
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) at any time for such Indemnified Holders, which firm shall be
designated in writing by the Holders of a majority in aggregate principal amount
of Notes held by such Indemnified Holders or by the Trustee acting on behalf of
the Holders of a majority in aggregate principal amount of Notes. DigitalNet
Holdings, the Company and the Subsidiary Guarantor shall be jointly and
severally liable for any settlement of any such action or proceeding effected
with the Company's prior written consent, which consent shall not be withheld
unreasonably, and DigitalNet Holdings, the Company and the Subsidiary Guarantor

                                       16
<Page>

agree to indemnify and hold harmless any Indemnified Holder from and against any
loss, claim, damage, liability or reasonable expense by reason of any settlement
of any action effected with the written consent of the Company. None of
DigitalNet Holdings, the Company or the Subsidiary Guarantor shall, without the
prior written consent of each Indemnified Holder, settle or compromise or
consent to the entry of judgment in or otherwise seek to terminate any pending
or threatened action, claim, litigation or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not any
Indemnified Holder is a party thereto), unless such settlement, compromise,
consent or termination includes an unconditional release of each Indemnified
Holder from all liability arising out of such action, claim, litigation or
proceeding.

     (b) Each Holder of Transfer Restricted Securities agrees, severally and not
jointly, to indemnify and hold harmless DigitalNet Holdings, the Company and the
Subsidiary Guarantor and their respective directors, officers of DigitalNet
Holdings, the Company or the Subsidiary Guarantor who sign a Registration
Statement, and any person controlling (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) the Company, and the
respective offices, directors, partners, employees, representatives and agents
of each such person, to the same extent as the foregoing indemnity from
DigitalNet Holdings, the Company and the Subsidiary Guarantor to each of the
Indemnified Holders, but only with respect to claims and actions based on
information relating to such Holder furnished in writing by such Holder
expressly for use in any Registration Statement. In case any action or
proceeding shall be brought against DigitalNet Holdings, the Company, the
Subsidiary Guarantor or their respective directors or officers or any such
controlling person in respect of which indemnity may be sought against a Holder
of Transfer Restricted Securities, such Holder shall have the rights and duties
given DigitalNet Holdings, the Company or the Subsidiary Guarantor and the
Subsidiary Guarantor or their respective directors or officers or such
controlling person shall have the rights and duties given to each Holder by the
preceding paragraph. In no event shall the liability of any selling Holder
hereunder be greater in amount than the dollar amount of the proceeds received
by such Holder upon the sale of the Securities giving rise to such
indemnification obligation.

     (c) If the indemnification provided for in this Section 8 is unavailable to
an indemnified party under Section 8(a) or Section 8(b) hereof (other than by
reason of exceptions provided in those Sections) in respect of any losses,
claims, damages, liabilities, judgments, actions or expenses referred to
therein, then each applicable indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative benefits
received by DigitalNet Holdings, the Company and the Subsidiary Guarantor, on
the one hand, and the Holders, on the other hand, from the Initial Placement
(which in the case of DigitalNet Holdings, the Company or the Subsidiary
Guarantor shall be deemed to be equal to the total gross proceeds from the
Initial Placement as set forth on the cover page of the Offering Memorandum),
and such Registration Statement, or if such allocation is not permitted by
applicable law, the relative fault of DigitalNet Holdings, the Company and the
Subsidiary Guarantor on the one hand, and of the Indemnified Holder, on the
other hand, in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative fault of DigitalNet Holdings,
the Company and the Subsidiary Guarantor on the one hand and of the Indemnified
Holder on the other shall be determined by reference to, among

                                       17
<Page>

other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company or by the Indemnified Holder and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses
referred to above shall be deemed to include, subject to the limitations set
forth in the second paragraph of Section 8(a), any legal or other fees or
expenses reasonably incurred by such party in connection with investigating or
defending any action or claim.

     DigitalNet Holdings, the Company, the Subsidiary Guarantor and each Holder
of Transfer Restricted Securities agree that it would not be just and equitable
if contribution pursuant to this Section 8(c) were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or expenses referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 8, none of the Holders (and its
related Indemnified Holders) shall be required to contribute, in the aggregate,
any amount in excess of the amount by which the total discount received by such
Holder with respect to the Initial Notes exceeds the amount of any damages which
such Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Holders' obligations to
contribute pursuant to this Section 8(c) are several in proportion to the
respective principal amount of Initial Notes held by each of the Holders
hereunder and not joint.

     SECTION 9. RULE 144A. DigitalNet Holdings, the Company and the Subsidiary
Guarantor hereby each agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding, to make available to any Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
from such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Securities Act in order to permit resales of such Transfer
Restricted Securities pursuant to Rule 144A.

     SECTION 10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Holder may
participate in any Underwritten Registration hereunder unless such Holder (a)
agrees to sell such Holder's Transfer Restricted Securities on the basis
provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (b) completes and executes all
reasonable questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up letters and other documents required under the terms of such
underwriting arrangements.

     SECTION 11. SELECTION OF UNDERWRITERS. The Holders of Transfer Restricted
Securities covered by the Shelf Registration Statement who desire to do so may
sell such Transfer Restricted Securities in an Underwritten Offering. In any
such Underwritten Offering, the

                                       18
<Page>

investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering; PROVIDED, that such investment bankers and managers must be
reasonably satisfactory to the Company.

     SECTION 12.  MISCELLANEOUS.

     (a) REMEDIES. DigitalNet Holdings, the Company and the Subsidiary Guarantor
each hereby agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this
Agreement and hereby agree to waive the defense in any action for specific
performance that a remedy at law would be adequate.

     (b) NO INCONSISTENT AGREEMENTS. DigitalNet Holdings and the Company will
not, and will cause the Subsidiary Guarantor not to, on or after the date of
this Agreement enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. None of DigitalNet Holdings, the
Company or the Subsidiary Guarantor has entered into any agreement granting any
registration rights with respect to its securities to any Person which would
allow the registration of such securities on the Exchange Offer Registration
Statement or any Shelf Registration Statement. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of DigitalNet Holdings, the Company's or the
Subsidiary Guarantor securities under any agreement in effect on the date
hereof.

     (c) ADJUSTMENTS AFFECTING THE NOTES. None of DigitalNet Holdings, the
Company or the Subsidiary Guarantor will take any action, or permit any change
to occur, with respect to the Notes that would materially and adversely affect
the ability of the Holders to Consummate any Exchange Offer.

     (d) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless the Company has obtained the
written consent of Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities. Notwithstanding the foregoing, a waiver or
consent to departure from the provisions hereof that relates exclusively to the
rights of Holders whose securities are being tendered pursuant to the Exchange
Offer and that does not affect directly or indirectly the rights of other
Holders whose securities are not being tendered pursuant to such Exchange Offer
may be given by the Holders of a majority of the outstanding principal amount of
Transfer Restricted Securities being tendered or registered; provided that, with
respect to any matter that directly affects the rights of any Initial Purchaser
hereunder in its capacity as such, the Company shall obtain the written consent
of each such Initial Purchaser with respect to which such amendment,
qualification, supplement, waiver, consent or departure is to be effective,
which consent shall not be unreasonably withheld.

     (e) NOTICES. All notices and other communications provided for or permitted
