        1.     Representations, Warranties, Covenants and Agreements.  The
Company further represents, warrants, covenants, and agrees with the
Administrative Agent for the benefit of the Lenders as follows:

               (a)     Ownership of Collateral; Security Interest Priority. At
the time any Collateral becomes subject to a security interest of the
Administrative Agent hereunder, unless the Administrative Agent and the Lenders
shall otherwise consent, the Company shall be deemed to have represented and
warranted that (i) the Company is the lawful owner of such Collateral and has
the right and authority to subject the same to the security interest of the
Administrative Agent; (ii) other than Permitted Liens (as defined in the Credit
Agreement) and lessors' interest with respect to any security interest in any
property leased by the Company as lessee, none of the Collateral is subject to
any Lien other than that in favor of the Administrative Agent and there is no
effective financing statement or other filing covering any of the Collateral on
file in any public office, other than in favor of the Administrative Agent. This
Security Agreement creates in favor of the Administrative Agent a valid
first-priority security interest, subject only to Permitted Liens, in the
Collateral enforceable against the Company and all third parties and securing
the payment of the Secured Obligations. All financing statements and other
documents necessary to perfect such security interest in the Collateral have
been delivered by the Company to the Administrative Agent for filing.

               (b)     Location of Offices, Records and Facilities. The
Company's chief executive office and chief place of business and the office
where the Company keeps its records concerning its accounts, contract rights,
chattel papers, instruments, general intangibles and other obligations arising
out of or in connection with the sale or lease of goods or the rendering of
services or otherwise ("Receivables") are located in the State of California,
County of Los Angeles, at 5933 W. Century Blvd., Suite 700, Los Angeles,
California, 90045. The Company will provide the Administrative Agent with at
least 40 days' prior written notice of any proposed change in the location of
its chief executive office. The Company's only other offices and facilities are
at the locations set forth in Schedule 1(b) hereto. The Company will provide the

its other offices and the facilities at which any assets of the Company are
located. The tax identification number of the Company is 95-3032229. The name of
the Company is Trident Data Systems, Inc. and the Company operates under no
other names. The Company shall not change its name without at least 40 days'
prior written notice to the Administrative Agent.

               (c)     Location of Inventory, Fixtures, Machinery and Equipment.
(i) All Collateral consisting of inventory is, and will be, located at the
locations listed on Schedule 1(c)(i) hereto, and at no other locations without
the prior written consent of the Administrative Agent; and (ii) all Collateral
consisting of fixtures, machinery or equipment, is, and will be, located at the
locations listed on Schedule 1(c)(ii) hereto, and at no other locations without
the prior written consent of the Administrative Agent. If the Collateral

<PAGE>

               (d)     Liens, Etc. The Company will keep the Collateral free at
all times from any and all liens, security interests or encumbrances other than
those described in Paragraph 1(a)(ii) and those consented to in writing by the
Required Lenders. The Company will not, without the prior written consent of the
Administrative Agent, sell, lease, license, transfer, assign or otherwise
dispose, or permit or suffer to be sold, leased, licensed, transferred, assigned
or otherwise disposed, any of the Collateral, except for, prior to an event of
default only (notwithstanding any other agreement), the following: inventory
sold in the ordinary course of business and other assets permitted to be sold,
leased, licensed, transferred, assigned or otherwise disposed under Section
5.2(i) of the Credit Agreement. The Administrative Agent or its attorneys may at
any and all reasonable times inspect the Collateral and for such purpose may
enter upon any and all premises where the Collateral is or might be kept or
located.

               (e)     Insurance. The Company shall keep the tangible Collateral
insured at all times against loss by theft, fire and other casualties. Said
insurance shall be issued by a company rated A- or better by Best and shall be
in amounts sufficient to protect the Administrative Agent and the Lenders
against any and all loss or damage to the Collateral. The policy or policies
which evidence said insurance shall be delivered to the Administrative Agent
upon request, shall contain a lender loss payable clause in favor of the
Administrative Agent, shall name the Administrative Agent for the benefit of the
Lenders as an additional insured, as its interest may appear, shall not permit
amendment, cancellation or termination without giving the Administrative Agent
at least 30 days' prior written notice thereof, and shall otherwise be in form
and substance satisfactory to the Administrative Agent. Reimbursement under any
liability insurance maintained by the Company pursuant to this Paragraph 1(e)
may be paid directly to the person who shall have incurred liability covered by
such insurance. In case of any loss involving loss to tangible Collateral, the
Company shall make or cause to be made the necessary repairs to or replacements
of such tangible Collateral and any proceeds of insurance maintained by the
Company pursuant to this paragraph 1(e) shall be paid to the Company by the
Administrative Agent as reimbursement for the costs of such repairs or
replacements; provided that if there is any event of default or any event or
condition which with notice or lapse of time or both would become an event of
default (whether before or after any event which caused any reimbursement under
any hazard insurance), or if such reimbursement is greater than $500,000, such
amounts shall be paid to and retained by the Administrative Agent for
application to the Secured Obligations whether or not then due or payable.

               (f)     Taxes, Etc. The Company will pay promptly, and within the
time that they can be paid without interest or penalty, any taxes, assessments
and similar imposts and charges, not being contested in good faith, which are
now or hereafter may become a Lien upon any of the Collateral. If the Company
fails to pay any such taxes, assessments or other imposts or charges in
accordance with this Paragraph 1(f), the Administrative Agent shall have the
option to do so and the Company agrees to repay forthwith all amounts so
expended by the Administrative Agent with interest at the Overdue Rate.

               (g)     Further Assurances. The Company will do all acts and
things and will execute all financing statements and writings reasonably
requested by the Administrative Agent to

establish, maintain and continue a perfected and valid security interest of the
Administrative Agent in the Collateral, and will promptly on demand pay all
reasonable costs and expenses of filing and recording all instruments, including
the costs of any searches deemed necessary by the Administrative Agent, to
establish and determine the validity and the priority of the Administrative
Agent's security interests. A carbon, photographic or other reproduction of this
Security Agreement or any financing statement covering the Collateral shall be
sufficient as a financing statement. Upon the request of the Administrative
Agent, the Company will provide information (including any copies of any
documents) regarding the government contracts of the Company, now existing or
hereafter existing from time to time, and will execute such documents reasonably
requested by the Administrative Agent to establish, maintain and continue a
perfected and valid security interest of the Administrative Agent in such
government contracts and to comply with the Assignment of Claims Act of 1940, as
amended.

               (h)     List of Patents, Copyrights, Mask Works and Trademarks.
Attached hereto as Schedule 1(h)(i) is a list of all unexpired and maintained
patents and patent applications owned by the Company. Attached hereto as
Schedule 1(h)(ii) is a list of all registered copyrights and all mask works and
applications therefor owned by the Company. Attached hereto as Schedule
1(h)(iii) is a list of all trademarks and service marks owned by the Company. If
the Company at any time owns any additional patents, copyrights, mask works,
trademarks or any applications therefor not listed on such schedules, the
Company shall give the Administrative Agent prompt written notice thereof and
hereby authorizes the Administrative Agent to modify this Agreement by amending
Schedules 1(h)(i), 1(h)(ii) and 1(h)(iii) to include all future patents,
copyrights, mask works, trademarks and applications therefor and agrees to
execute all further instruments and agreements, if any, if requested by the
Administrative Agent to evidence the Administrative Agent's interest therein.

               (i)     Maintenance of Tangible Collateral. The Company will
cause the tangible Collateral material to the conduct of its business to be
maintained and preserved in the same condition, repair and working order as when
new, ordinary wear and tear excepted, and in accordance with any manufacturer's
manual, and shall forthwith, or, in the case of any loss or damage to any of the
tangible Collateral as quickly as practicable after the occurrence thereof, make
or cause to be made all repairs, replacements, and other improvements which are
necessary or desirable to such end. The Company shall promptly furnish to the
Administrative Agent a statement respecting any loss or damage to any of the
tangible Collateral.

               (j)     Special Rights Regarding Receivables. The Administrative
Agent or any of its agents may, at any time and from time to time in its sole
discretion upon the existence of any event of default under this Security
Agreement, verify, directly with each person (collectively, the "Obligors")
which owes any Receivables to the Company, the Receivables in any manner. The
Administrative Agent or any of its agents may, at any time from time to time
after and during the continuance of an event of default under this Security
Agreement, notify the Obligors of the security interest of the Administrative
Agent in the Collateral and/or direct such account debtors that all payments in
connection with such obligations and the Collateral be made directly to the
Administrative Agent in the Administrative Agent's name. If the Administrative
Agent or any of its

                          GUARANTOR SECURITY AGREEMENT

                                      -6-
<PAGE>

agents shall collect such obligations directly from the Obligors, the
Administrative Agent or any of its agents shall have the right to resolve any
disputes relating to returned goods directly with the Obligors in such manner
and on such terms as the Administrative Agent or any of its agents shall deem
appropriate. The Company directs and authorizes any and all of its present and
future account debtors to comply with requests for information from the
Administrative Agent, the Administrative Agent's designees and agents and/or
auditors, relating to any and all business transactions between the Company and
the Obligors. The Company further directs and authorizes all of its Obligors
upon receiving a notice or request sent by the Administrative Agent or the
Administrative Agent's agents or designees to pay directly to the Administrative
Agent any and all sums of money or proceeds now or hereafter owing by the
Obligors to the Company, and any such payment shall act as a discharge of any
debt of such Obligor to the Company in the same manner as if such payment had
been made directly to the Company. After and during the continuance of an event
of default, (i) all amounts and proceeds (including instruments) received by the
Company in respect of the Receivables shall be received in trust for the benefit
of the Administrative Agent hereunder, shall be segregated from other funds of
the Company and shall be forthwith paid over to the Administrative Agent in the
same form as so received (with any necessary endorsement) to be held as cash
collateral and either (A) released to the Company so long as no event of default
shall have occurred and be continuing or (B) if any event of default shall have
occurred and be continuing, applied by the Administrative Agent to the Secured
Obligations, whether or not then due or payable, and (ii) the Company shall not
adjust, settle or compromise the amount or payment of any Receivable, release
wholly or partly any Obligor thereof, or allow any credit or discount thereon.
The Company agrees to take any and all action as the Administrative Agent may
reasonably request to assist the Administrative Agent in exercising the rights
described in this Paragraph 1(j).

               (k)     Maintenance of Intellectual Property and Other Intangible
Collateral. The Company shall preserve and maintain all rights of the Company
and the Administrative Agent in all material Intellectual Property and all other
material intangible Collateral, including without limitation the payment of all
maintenance fees, filing fees and the taking of all appropriate action at the
Company's expense to halt the infringement of any of the Intellectual Property
or other Collateral, provided that, with respect to halting the infringement of
any Intellectual Property or other Collateral, the Company does not need to take
all such appropriate action if the Company has, or after an event of default the
Required Lenders have, reasonably determined that it is not in its best interest
to demand or enforce cessation of such infringement or other conduct because it
is either not material or because the adverse consequences to the Company would
outweigh the benefits gained by such demand or enforcement.

        2.     Events of Default.  The occurrence of any Event of Default under
the Credit Agreement shall be deemed an event of default under this Security
Agreement.

        3.     Remedies. Upon the occurrence of any event of default specified
in Paragraph 2 hereof, the Administrative Agent shall have and may exercise any
one or more of the rights and remedies provided to it under this Security
Agreement or any of the other Operative Documents or provided by law, including
but not limited to all of the rights and remedies of a secured party under

                          GUARANTOR SECURITY AGREEMENT

<PAGE>

the Uniform Commercial Code of the State of North Carolina, and the Company
hereby agrees to assemble the Collateral and make it available to the
Administrative Agent at a place to be designated by the Administrative Agent
which is reasonably convenient to both parties, authorizes the Administrative
Agent to take possession of the Collateral with or without demand and with or
without process of law and to sell and dispose of the same at public or private
sale and to apply the proceeds of such sale to the costs and expenses thereof
(including reasonable attorneys' fees and disbursements, incurred by the
Administrative Agent or any Lender) and then to the payment and satisfaction of
the Secured Obligations in the manner specified in Section 6.3 of the Credit
Agreement. Any requirement of reasonable notice shall be met if the
Administrative Agent sends such notice to the Company, by registered or
certified mail, at least 5 days prior to the date of sale, disposition or other
event giving rise to a required notice. The Administrative Agent or any Lender
may be the purchaser at any such sale. The Company expressly authorizes such
sale or sales of the Collateral in advance of and to the exclusion of any sale
or sales of or other realization upon any other collateral securing the Secured
Obligations. The Administrative Agent shall have no obligation to preserve
rights against prior parties. The Company hereby waives as to the Administrative
Agent and each Lender any right of subrogation or marshalling of such Collateral
and any other collateral for the Secured Obligations. To this end, the Company
hereby expressly agrees that any such collateral or other security of the
Company or any other party which the Administrative Agent may hold, or which may
come to any of the Lenders or any of their possession, may be dealt with in all
respects and particulars as though this Security Agreement were not in
existence. The parties hereto further agree that public sale of the Collateral
by auction conducted in any county in which any Collateral is located or in
which the Administrative Agent or the Company does business after advertisement
of the time and place thereof shall, among other manners of public and private
sale, be deemed to be a commercially reasonable disposition of the Collateral.
The Company shall be liable for any deficiency remaining after disposition of
the Collateral.

        4.     Special Remedies Concerning Certain Collateral.

               (a)     Upon the occurrence of any event of default, the Company
shall, if requested to do so in writing by the Administrative Agent, and to the
extent so requested (i) promptly collect and enforce payment of all amounts due
the Company on account of, in payment of, or in connection with, any of the
Collateral, (ii) hold all payments in the form received by the Company as
trustee for the Administrative Agent, without commingling with any funds
belonging to the Company, and (iii) forthwith deliver all such payments to the
Administrative Agent with endorsement to the Administrative Agent's order of any
checks or similar instruments.

               (b)     Upon the occurrence of any event of default, the Company
shall, if requested to do so in writing by the Administrative Agent, and to the
extent so requested, notify all Obligors and other persons with obligations to
the Company on account of or in connection with any of the Collateral of the
security interest of the Administrative Agent in the Collateral and direct such
account debtors and other persons that all payments in connection with such
obligations and the Collateral be made directly to the Administrative Agent. The
Administrative Agent itself may,

                          GUARANTOR SECURITY AGREEMENT

                                      -8-
<PAGE>

upon the occurrence of an event of default, so notify and direct any such
account debtor or other person that such payments are to be made directly to the
Administrative Agent.

               (c)     Upon the occurrence of any event of default, for purposes
of assisting the Administrative Agent in exercising its rights and remedies
provided to it under this Security Agreement, the Company (i) hereby irrevocably
constitutes and appoints the Administrative Agent its true and lawful attorney,
for and in the Company's name, place and stead, to collect, demand, receive, sue
for, compromise, and give good and sufficient releases for, any monies due or to
become due on account of, in payment of, or in connection with the Collateral,
(ii) hereby irrevocably authorizes the Administrative Agent to endorse the name
of the Company, upon any checks, drafts, or similar items which are received in
payment of, or in connection with, any of the Collateral, and to do all things
necessary in order to reduce the same to money, (iii) with respect to any
Collateral, hereby irrevocably assents to all extensions or postponements of the
time of payment thereof or any other indulgence in connection therewith, to each
substitution, exchange or release of Collateral, to the addition or release of
any party primarily or secondarily liable, to the acceptance of partial payments
thereon and the settlement, compromise or adjustment (including adjustment of
insurance payments) thereof, all in such manner and at such time or times as the
Administrative Agent shall deem advisable, and (iv) hereby irrevocably
authorizes the Administrative Agent to notify the post office authorities to
change the address for delivery of the Company's mail to an address designated
by the Administrative Agent, and the Administrative Agent may receive, open and
dispose of all mail addressed to the Company. Notwithstanding any other
provisions of this Security Agreement, it is expressly understood and agreed
that the Administrative Agent shall have no duty, and shall not be obligated in
any manner, to make any demand or to make any inquiry as to the nature or
sufficiency of any payments received by it or to present or file any claim or
take any other action to collect or enforce the payment of any amounts due or to
become due on account of or in connection with any of the Collateral.

        5.     Remedies Cumulative. No right or remedy conferred upon or
reserved to the Administrative Agent under any Operative Document is intended to
be exclusive of any other right or remedy, and every right and remedy shall be
cumulative in addition to every other right or remedy given hereunder or now or
hereafter existing under any applicable law. Every right and remedy of the
Administrative Agent under any Operative Document or under applicable law may be
exercised from time to time and as often as may be deemed expedient by the
Administrative Agent. To the extent that it lawfully may, the Company agrees
that it will not at any time insist upon, plead, or in any manner whatever claim
or take any benefit or advantage of any applicable present or future stay,
extension or moratorium law, which may affect observance or performance of any
provisions of any Operative Document; nor will it claim, take or insist upon any
benefit or advantage of any present or future law providing for the valuation or
appraisal of any security for its obligations under any Operative Document prior
to any sale or sales thereof which may be made under or by virtue of any
instrument governing the same; nor will the Company, after any such sale or
sales, claim or exercise any right, under any applicable law to redeem any
portion of such security so sold.

                                      -9-

        6.     Conduct No Waiver. No waiver of default shall be effective unless
in writing executed by the Administrative Agent and waiver of any default or
forbearance on the part of the Administrative Agent in enforcing any of its
rights under this Security Agreement shall not operate as a waiver of any other
default or of the same default on a future occasion or of such right.

SECURITY AGREEMENT SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE

hereunder are solely to protect its and the Lenders' interests in the Collateral
and shall not impose any duty upon it to exercise any such powers. Except for

actually received by it hereunder, the Administrative Agent shall have no duty
as to any Collateral or as to the taking of any necessary steps to preserve
rights against prior parties or any other rights pertaining to any Collateral.

        10.    Amendments.  None of the terms and provisions of this Security
Agreement may be modified or amended in any way except by an instrument in
writing executed by each of the parties hereto.

        11.    Severability.  If any one or more provisions of this Security
Agreement should be invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected, impaired or prejudiced thereby.

        12.    Expenses. (a) The Company agrees to indemnify the Administrative
Agent and the Lenders and their respective officers, directors, employees,
affiliates and agents from and against any and all claims, losses and
liabilities growing out of or resulting from this Security Agreement (including,
without limitation, enforcement of this Security Agreement), except claims,
losses or liabilities resulting from such indemnified party's gross negligence
or willful misconduct.

               (b)     The Company will, upon demand, pay to the Administrative
Agent an amount of any and all reasonable expenses, including the reasonable
fees and disbursements of its counsel and of any experts and agents, which the
Administrative Agent or any Lender may incur in connection with (i) the
administration of this Security Agreement, (ii) the custody, preservation, use
or operation of, or the sale of, collection from or other realization upon, any
of the Collateral, (iii) the exercise or enforcement of any of the rights of the

shall create a continuing security interest in the Collateral and shall be
binding upon the Company, its successors and assigns, and inure, together with
the rights and remedies of the Administrative Agent hereunder, to the benefit of
the Administrative Agent and the Lenders and their respective successors,
transferees and assigns. Upon the payment in full in immediately available funds
of all of the Secured Obligations and the termination of all commitments to lend
under the Operative Documents, the security interest granted hereunder shall
terminate and all rights to the Collateral shall revert to the Company.

        14.    Binding Arbitration; Waiver of Jury Trial.

               (a)     Binding Arbitration. Upon demand of any party, whether
made before or after institution of any judicial proceeding, any dispute, claim
or controversy arising out of, connected with or relating to this Security
Agreement or any other of the Operative Documents ("Disputes"), between or among
parties to this Security Agreement, or any other Operative Document shall be
resolved by binding arbitration as provided herein. Institution of a judicial
proceeding by a party does not waive the right of that party to demand
arbitration hereunder. Disputes may include, without limitation, tort claims,
counterclaims, claims brought as class actions, claims arising from Operative
Documents executed in the future, disputes as to whether a matter is subject to
arbitration, or claims concerning any aspect of the past, present or future

                                      -11-
<PAGE>

relationships arising out of or connected with the Operative Documents.
Arbitration shall be conducted under and governed by the Commercial Financial
Disputes Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association (the "AAA") and the Federal Arbitration Act. All arbitration
hearings shall be conducted in Charlotte, North Carolina. The expedited
procedures set forth in Rule 51, et seq. of the Arbitration Rules shall be
applicable to claims of less than $1,000,000. All applicable statutes of
limitations shall apply to any Dispute. A judgment upon the award may be entered
in any court having jurisdiction. Notwithstanding anything foregoing to the
contrary, any arbitration proceeding demanded hereunder shall begin within
ninety (90) days after such demand thereof and shall be concluded within
one-hundred twenty (120) days after such demand. These time limitations may not
be extended unless a party hereto shows cause for extension and then such
extension shall not exceed a total of sixty (60) days. The panel from which all
arbitrators are selected shall be comprised of licensed attorneys selected from
the Commercial Finance Dispute Arbitration Panel of the AAA. The single
arbitrator selected for expedited procedure shall be a retired judge from the
highest court of general jurisdiction, state or federal, of the state where the
hearing will be conducted. The parties hereto do not waive any applicable
Federal or state substantive law except as provided herein.

        (b)    JURY TRIAL. THE ADMINISTRATIVE AGENT, EACH LENDER AND THE COMPANY
HEREBY ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE IRREVOCABLY
WAIVED THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM
OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS SECURITY
AGREEMENT OR THE OTHER OPERATIVE DOCUMENTS, ANY RIGHTS OR OBLIGATIONS HEREUNDER
OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND OBLIGATIONS.

        (c)    Preservation of Certain Remedies. Notwithstanding the preceding
binding arbitration provisions, the parties hereto and the other Operative
Documents preserve, without diminution, certain remedies that such Persons may
employ or exercise freely, either alone, in conjunction with or during a
Dispute. Each such Person shall have and hereby reserves the right to proceed in
any court of proper jurisdiction or by self help to exercise or prosecute the
following remedies: (i) all rights to foreclose against any real or personal
property or other security by exercising a power of sale granted in the
Operative Documents or under applicable law or by judicial foreclosure and sale,
(ii) all rights of self help including peaceful occupation of property and
collection of rents, set off, and peaceful possession of property, (iii)
obtaining provisional or ancillary remedies including injunctive relief,
sequestration, garnishment, attachment, appointment of receiver and in filing an
involuntary bankruptcy proceeding, and (iv) when applicable, a judgment by
confession of judgment. Preservation of these remedies does not limit the power
of an arbitrator to grant similar remedies that may be requested by a party in a
Dispute.

        15.    Security Interest Absolute. The obligations of the Company under
this Security Agreement are independent of the Secured Obligations, and a
separate action or actions may be brought and prosecuted against the Company to
enforce this Security Agreement, irrespective of whether any action is brought
against Veridian or whether Veridian is joined in any such action or

actions. All rights of the Administrative Agent and the Lenders and the pledge,
assignment and security interest hereunder, and all obligations of the Company
hereunder, shall be absolute and unconditional, irrespective of: (a) any lack of
validity or enforceability of the Credit Agreement, the Notes or any other
agreement or instrument relating thereto; (b) any change in the time, manner or
place of payment of, or in any other term of, all or any of the Secured
Obligations, or any other amendment or waiver of or any consent to any departure
from the Credit Agreement or the Notes, including, without limitation, any
increase in the Secured Obligations resulting from the extension of additional
credit to Veridian or any of its Subsidiaries or otherwise; (c) any taking,
exchange, release or non-perfection of any other collateral, or any taking,
release or amendment or waiver of or consent to departure from any guaranty, for
all or any of the Secured Obligations; (d) any manner of application of
collateral, or proceeds thereof, to all or any of the Secured Obligations, or
any manner of sale or other disposition of any collateral for all or any of the
Secured Obligations or any other assets of Veridian or any of its Subsidiaries;
(e) any change, restructuring or termination of the corporate structure or
existence of Veridian or any of its Subsidiaries; or (f) any other circumstance
which might otherwise constitute a defense available to, or a discharge of, the
Company or a third party grantor of a security interest.

                    COLLATERAL ASSIGNMENT OF REPRESENTATIONS,
                            WARRANTIES AND COVENANTS

                This Collateral Assignment of Representations, Warranties,
Covenants and Indemnities (this "Assignment"), dated as of September 7, 1999,

an office at 1970 Chain Bridge Road, VA 1942, McLean, Virginia 22102-4099
("Administrative Agent"), as Administrative Agent for the Lenders party from
time to time to the Credit Agreement referred to below.

                                   WITNESSETH:

                WHEREAS, Company and Trident Data Systems, Inc., a California
corporation ("Trident"), have entered into that certain Stock Purchase Agreement
dated as of July 22, 1999 (as the same may hereafter be amended, supplemented,
amended and restated, renewed or otherwise modified from time to time, the
"Agreement");

                WHEREAS, pursuant to the Agreement, the Trident has made certain
representations and warranties to, and covenants and agreements with, Company
(collectively, the "Representations, Warranties and Covenants");

                WHEREAS, Company, Administrative Agent and certain Lenders (as
defined in the Credit Agreement referred to herein) have entered into that
certain Credit Agreement, dated as of the date hereof (as the same may be
amended, supplemented, amended and restated, renewed or otherwise modified from
time to time, the "Credit Agreement"), and, pursuant to the Security Agreement,
dated as of the date hereof, Administrative Agent has been granted security
interests in and liens on all of Company's assets,

                WHEREAS, Administrative Agent has required, as a condition to
its entering into the Credit Agreement, that Company assigns to Administrative
Agent, as additional security for the repayment of the Secured Obligations (as
defined in the Credit Agreement), all of Company's rights and remedies with
respect to the Representations, Warranties and Covenants;

                NOW, THEREFORE, in consideration of the premises set forth and
for other good and valuable consideration, Company agrees as follows:

                1.      Company hereby collaterally assigns and transfers to
Administrative Agent for the benefit of the Lenders, and grants a security
interest in, as additional security for the repayment in full of the Secured

<PAGE>

Warranties and Covenants, and any payments due from the Trident to Company under

                2.      Following the occurrence and continuation of an Event of
Default, a) the Company hereby irrevocably authorizes and empowers
Administrative Agent or its agents, in the sole discretion of Administrative
Agent, to assert, either directly or on behalf of Company, any claims Company
may, from time to time, have against the Trident with respect to the
Representations, Warranties and Covenants or with respect to any payments due
from the Trident to Company under or pursuant to the Agreement, as

set forth hereinabove. Notwithstanding the foregoing, Administrative Agent
agrees that until an Event of Default (which for purposes of this Assignment
shall mean an Event of Default as defined under the Credit Agreement) shall
occur Company alone shall have the right to assert claims against the Trident in
connection with the Representations, Warranties and Covenants, provided that
Company gives Administrative Agent written notice of its intention to assert any
such claims and keeps Administrative Agent informed of the status of any
proceedings concerning such claims.

                3.      Company shall keep Administrative Agent informed of all
circumstances known to Company bearing upon the Representations, Warranties and
Covenants, and Company shall not waive any of its rights or remedies under the

shall have their defined meanings under the Credit Agreement.

                6.      At any time or from time to time, upon Administrative
Agent's written request, Company will execute and deliver to Administrative
Agent such further documents and do such other acts and things as Administrative
Agent may request in order further to effect the purposes of this Assignment,
including, without limitation, the filing or recording of this Assignment or any

<PAGE>

Company hereby authorizes Administrative Agent to effect any such filing or
recording as aforesaid (including the filing of any such financing statements or
amendments thereto without the signature of Company), and Administrative Agent's
costs and expenses with respect thereto shall be payable by Company on demand.

                7.      Company hereby represents and warrants that (i) the

be binding upon Company or upon any of Company's assets and will not result in
the creation or imposition of any lien, charge or encumbrance on or security
interest in any of the assets of Company except as contemplated by this
Assignment.

                8.      Company (i) will not assign, pledge or otherwise
encumber any of its right, title or interest under, in or to the Agreement to
anyone other than Administrative Agent and its successors or assigns; (ii) will
not take or omit to take any action, the taking or omission of which could

default thereunder; (v) will deliver to Administrative Agent a copy of each
demand, notice, communication or document (except those received in the ordinary
course of business) delivered to it in any way relating to the Agreement; and
(vi) will not grant any consents or waivers under the Agreement without
