ITEM 5.   OTHER EVENTS.

     On September 25, 1998, ODS Networks, Inc. ("the Registrant") acquired 
certain assets from Science Applications International Corporation, a 
Delaware corporation ("SAIC"), including the software program Computer Misuse 
and Detection System ("CMDS"), and certain products under development 
including Vunerability Assessment System ("VAS"), Audit Monitoring and 
Intrusion Detection System ("AMIDS") and Malicious Code Detection and 
Eradication System ("MCDES"), and certain other assets, including computer 
hardware and software and $1,500,000 in cash (collectively, the "Assets").  
In consideration for the Assets, the Registrant issued to SAIC (i) 1,600,000 
shares of the Registrant's common stock, par value $0.01 per share, (ii) a 
Warrant to purchase 750,000 shares of the Registrant's common stock at an 
exercise price of $8.00 per share, exercisable at any time on or before March 
25, 2000, and (iii) a Warrant to purchase 750,000 shares of the Registrant's 
common stock at an exercise price of $10.50 per share, exercisable at any 
time on or before September 25, 2000.

     Pursuant to the Stockholder and Voting Agreement dated as of September 
25, 1998 by and among the Registrant, SAIC and certain stockholders of the 
Registrant, the Registrant and such stockholders have agreed, for so long as 
SAIC beneficially owns, directly or indirectly, the lesser of (i) five 
percent (5%) or more of the outstanding shares of common stock of the 
Registrant or (ii) 1,000,000 shares of common stock of the Registrant to 
cause the Board of Directors of the Registrant to be increased from five (5) 
to six (6) members and for a designee of SAIC to be elected to the Board, and 
granted certain other rights with respect to further increases in the number 
of members of the Board of Directors of the Registrant, approval rights with 
respect to certain corporate transactions and certain preemptive rights. As a 
condition to the acquisition of the Assets, and effective as of September 25, 
1998, the Board of Directors of the Registrant was increased to six (6) 
members and William A. Roper, Chief Financial Officer of SAIC, was elected to 
the Registrant's Board of Directors.  

     The terms of the acquisition were the result of arm's-length 
negotiations between the Registrant and SAIC.  All shares of common stock 
issued in this transaction were issued (and will be issued) out of 
Registrant's authorized but unissued Common Stock.  The securities issued to 
SAIC were issued pursuant to the exemption from the registration requirements 
of the Securities Act of 1933, as amended (the "Securities Act") provided by 
Section 4(2) thereof.  The Registrant granted SAIC certain rights with 
respect the registration under the Securities Act of the shares of common 
stock issued to SAIC, and any shares issued to SAIC upon exercise of the 
Warrants.  

     The Registrant is not aware of any pre-existing material relationships 
between SAIC and the Registrant, its affiliates, its directors or officers, 
or any associate of any such director or officer.

encumbrances other than any liens or encumbrances created by or imposed upon 
the holders thereof and have been issued in compliance with all federal and 
state securities laws. The shares of Common Stock to be issued pursuant to 
this Agreement, the $8.00 Warrant, the $10.50 Warrant and the shares of 
Common Stock to be issued upon the exercise of either such warrant shall be 
duly authorized, validly issued, fully paid and non-assessable, and free of 
preemptive rights or rights of first refusal created by statute, the 
Company's Certificate of Incorporation or Bylaws or any agreement to which 
the Company is a party or by which it is bound and, based on the 
representations of SAIC contained in Sections 4.6, 4.7 and 4.8 of this 
Agreement, shall be issued in compliance with all federal and state 
securities laws. 

          3.3    AUTHORITY. The Company has full corporate power and 
authority to enter into this Agreement and to consummate the transactions 
contemplated hereby.  The Company has taken all action required by law, its 
Certificate of Incorporation and Bylaws or otherwise to authorize the 
execution and delivery of this Agreement and the transactions contemplated 
hereby.  This Agreement and all other agreements delivered hereunder are 
valid and binding agreements of the Company enforceable in accordance with 
their terms, except that:  (a) the enforceability of this Agreement and all 
other agreements delivered hereunder may be subject to general principles of 
equity, regardless of whether such enforceability is considered in a 
proceeding in equity or at law; and (b) the enforceability of this Agreement 
and all other agreements delivered hereunder may be subject to or limited by 
bankruptcy, insolvency, reorganization, arrangement, moratorium, or other 
similar laws relating to or affecting the rights of creditors generally.  The 
execution and delivery of this Agreement does not, and the consummation of 
the transactions contemplated hereby shall not, conflict with, or result in 
any violation of, or default under (with or without notice or lapse of time, 
or both), or give rise to a right of termination, cancellation or 
acceleration of any obligation or loss of a benefit under (i) 


                                      4

<PAGE>

any provision of the Certificate of Incorporation or Bylaws of the Company or 
(ii) any material mortgage, indenture, lease, contract or other agreement or 
instrument, permit, concession, franchise, license, judgment, order, decree, 
statute, law, ordinance, rule or regulation applicable to the Company or its 
properties or assets.  Assuming the accuracy of the representations and 
warranties of SAIC in Sections 4.6, 4.7 and 4.8 of this Agreement, no 
consent, approval order or authorization of, or registration, declaration or 
filing with, any court, administrative agency or commission or other 
governmental authority (each a "GOVERNMENTAL ENTITY"), is required by or with 
respect to the Company or in connection with the execution and delivery of 
this Agreement by the Company or the consummation by the Company of the 
transactions contemplated hereby, except for (i) such approval, or 
termination of the waiting period, as may be required under the 
Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR") prior to 
exercise of either of the Warrants and (ii) such filings or registrations as 
may be required under federal and state securities laws. 

          3.4    SEC DOCUMENTS; FINANCIAL STATEMENTS.  The Company has made

prospectus in the form filed pursuant to Rule 424(b) of the Securities Act), 
definitive proxy statement, and other filing filed with the Securities and 
Exchange Commission ("SEC") by the Company since June 30, 1998 (collectively, 
the "COMPANY SEC DOCUMENTS").  In addition, the Company has made available to 
SAIC all exhibits to the Company SEC Documents filed prior to the date 
hereof, and shall promptly make available to SAIC all exhibits to any 
additional Company SEC Documents filed prior to the Closing.  As of their 
respective filing dates, the Company SEC Documents were filed on a timely 
basis and complied in all material respects with the requirements of the 
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT") and the 
Securities Act, and none of the Company SEC Documents contained any untrue 
statement of a material fact or omitted to state a material fact required to 
be stated therein or necessary to make the statements made therein, in light 
of the circumstances in which they were made, not misleading except to the 
extent corrected by a subsequently filed Company SEC Document.  The financial 
statements of the Company, including the notes thereto, included in the 
Company SEC Documents (the "COMPANY FINANCIAL STATEMENTS") were complete and 
correct in all material respects as of their respective dates, complied as to 
form in all material respects with applicable accounting requirements and 
with the published rules and regulations of the SEC with respect thereto as 
of their respective dates, and have been prepared in accordance with 
generally accepted accounting principles applied on a basis consistent 
throughout the periods indicated and consistent with each other (except as 
may be indicated in the notes thereto or, in the case of unaudited statements 
included in Quarterly Reports on Form 10-Qs, as permitted by Form 10-Q of the 
SEC).  The Company Financial Statements fairly present the consolidated 
financial condition and operating results of the Company and its subsidiaries 
at the dates and during the periods indicated therein (subject, in the case 
of unaudited statements, to normal, recurring year-end adjustments).

          3.5    ABSENCE OF UNDISCLOSED LIABILITIES.  The Company has no 
material obligations or liabilities of any nature (matured or unmatured, 
fixed or contingent) other than (i) those set forth or adequately provided 
for in the Balance Sheet included in the Company's Annual Report on Form 10-Q 
for the quarterly period ended June 30, 1998 (the "COMPANY BALANCE SHEET"), 
(ii) those incurred in the ordinary course of business and not required to be 
set forth in the Company Balance Sheet under generally accepted accounting 
principles, and (iii) 


                                      5

<PAGE>

those incurred in the ordinary course of business since the Company Balance 
Sheet Date and consistent with past practice.

          3.6    BROKER'S AND FINDERS' FEES.  The Company has not incurred, 
nor shall it incur, directly or indirectly, any liability for brokerage or 
finders' fees or agents' commissions or investment bankers' fees or any 
similar charges in connection with this Agreement or any transaction 
contemplated hereby.

          3.7    BOARD APPROVAL.  The Board of Directors of the Company have 
approved this Agreement and the transactions contemplated hereby.  No vote or 
consent of the Company's stockholders is required for the consummation of the 
transactions contemplated hereby.

          3.8    NO MATERIAL ADVERSE CHANGE.  Since the date of the balance 
sheet included in the Company's most recently filed report on Form 10-Q or 
Form 10-K, the Company has conducted its business in the ordinary course and 
there has not occurred: (a) any material adverse change in the financial 
condition, liabilities, assets or business of the Company other than 
continuing operating losses and declining stock price; (b) any amendment or 
change in the Certificate of Incorporation or Bylaws of the Company; or (c) 
any damage to, destruction or loss of any assets of the Company, (whether or 
not covered by insurance) that materially and adversely affects the financial 
condition or business of the Company.

          3.9    LITIGATION.  There is no action, suit, proceeding, claim, 
arbitration or investigation pending, or as to which the Company has received 
any notice of assertion against the Company which in any manner challenges or 
seeks to prevent, enjoin, alter or materially delay any of the transactions 
contemplated by this Agreement.

          3.10   REPRESENTATIONS COMPLETE.  None of the representations or 
warranties made by the Company herein or in any Schedule hereto, including 
the Company Disclosure Schedule, or certificate furnished by the Company 
pursuant to this Agreement, or the Company SEC Documents, when all such 
documents are read together in their entirety, contains or shall contain at 
the Closing any untrue statement of a material fact, or omits or shall omit 
at the Closing to state any material fact necessary in order to make the 
statements contained herein or therein, in the light of the circumstances 
under which made, not misleading.
                                          
                                  ARTICLE IV
                                          
                    REPRESENTATIONS AND WARRANTIES OF SAIC

     For the purposes of this Article IV, any reference to "SAIC's Knowledge" 
means actual knowledge of the persons that are listed on SCHEDULE IV and no 
other persons.

     Except as disclosed in a document of even date herewith and delivered by 
the SAIC to the Company prior to the execution and delivery of this Agreement 
(the "SAIC DISCLOSURE SCHEDULE"), the SAIC represents and warrants to Company 
as follows:


                                      6

<PAGE>

          4.1    CORPORATE ORGANIZATION.  SAIC is a corporation duly 
organized, validly existing and in good standing under the laws of the State 
of Delaware. SAIC has full corporate power and authority to carry on its 
business as it is now being conducted.

          4.2    AUTHORIZATION.  SAIC has full corporate power and authority 
to enter into this Agreement and to consummate the transactions contemplated 
hereby.  SAIC has taken all action required by law, its Certificate of 
Incorporation and Bylaws or otherwise to authorize the execution and delivery 
of this Agreement and the transactions contemplated hereby.  This Agreement 
and all other agreements delivered hereunder are valid and binding agreements 
of SAIC enforceable in accordance with their terms, except that:  (a) the 
enforceability of this Agreement and all other agreements delivered hereunder 
may be subject to general principles of equity, regardless of whether such 
enforceability is considered in a proceeding in equity or at law; and (b) the 
enforceability of this Agreement and all other agreements delivered hereunder 
may be subject to or limited by bankruptcy, insolvency, reorganization, 
arrangement, moratorium, or other similar laws relating to or affecting the 
rights of creditors generally.

          4.3    NO VIOLATION.  Neither the execution and delivery of this 
Agreement nor the consummation of the transactions contemplated hereby shall 
violate any provisions of the Certificate of Incorporation or Bylaws of SAIC 
or violate, or be in conflict with, or constitute a default under, or cause 
the acceleration of the maturity of any material debt or material obligation 
pursuant to, any material agreement or material commitment to which SAIC is a 
party or by which SAIC is bound, or violate any statute or law or any 
judgment, decree, order, regulation or rule of any court or governmental 
authority.

          4.4    BROKERS AND FINDERS.  SAIC has not incurred, nor shall it 
incur, directly or indirectly, any liability for brokerage or finders' fees 
or agents' commissions or investment bankers' fees or any similar charges in 
connection with this Agreement or any transaction contemplated hereby.

          4.5    CORPORATE APPROVAL.  All necessary corporate actions have 
been taken by SAIC for the approval of SAIC to enter this Agreement and the 
transactions contemplated hereby.  No vote or consent of the stockholders of 
SAIC is required for the consummation of the transactions contemplated hereby.

          4.6    INVESTMENT INTENT.  SAIC is purchasing the Shares and the 
Warrants for its own account not as a nominee or agent, and not with a view 
to the resale or distribution of any part thereof, and SAIC has no present 
intention of selling, granting any participation in, or otherwise 
distributing the same, and does not have any contract, undertaking, agreement 
or arrangement with any person to sell, transfer or grant participation to 
such person or to any third person, with respect to any of such securities.

          4.7    ACCESS TO INFORMATION.  SAIC has received or has had full 
access to all the information it considers necessary or appropriate to make 
an informed investment decision with respect to the Shares and Warrants and 
has received a copy of and reviewed to the extent SAIC deems necessary, the 
Company's Annual Report on Form 10-K for the year ended December 31, 1997, 
Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 1998 
and June 


                                      7

<PAGE>

30, 1998, Proxy Statement dated March 20, 1998 and 1997 Annual Report to 
Stockholders.  SAIC has had an opportunity to ask questions of and receive 
answers from the Company and to obtain additional information (to the extent 
the Company possessed such information or could acquire it without 
unreasonable effort or expense) necessary to verify any information furnished 
to SAIC or to which the Company has access.

          4.8    ACCREDITED INVESTOR.  SAIC is an "accredited investor" 
within the meaning of SEC Rule 501 of Regulation D, as presently in effect.

          4.9    RESTRICTED SECURITIES.  SAIC understands that the Shares and 
Warrants (and the shares to be issued upon exercise of the Warrants) are 
characterized as "restricted securities" under the federal securities laws 
inasmuch as they are being acquired from the Company in a transaction not 
involving a public offering and that under such laws and applicable 
regulations such securities may be resold without registration under the 
Securities Act only in certain limited circumstances.  In this connection, 
SAIC represents that it is familiar with SEC Rule 144, as presently in 
effect, and understands the resale limitations imposed thereby and by the 
Securities Act.

          4.10   FURTHER LIMITATIONS ON DISPOSITION.  SAIC agrees not to 
offer, sell, exchange, transfer, pledge or otherwise dispose of any of the 
Shares, the Warrants or shares issuable upon exercise of the Warrants except 
in compliance with the Stockholder Voting Agreement and unless at that time 
either:

          (a)    such transaction is permitted pursuant to the provisions of
     Rule 144 under the Securities Act;

          (b)    counsel representing SAIC reasonably satisfactory to the
     Company shall have advised the Company in a written opinion letter
     reasonably satisfactory to the Company and the Company's counsel, and upon
     which the Company and its counsel may rely, that no registration under the
     Securities Act is required in connection with the proposed sale, transfer
     or other disposition;

          (c)    a registration statement under the Securities Act (a
     "REGISTRATION STATEMENT") covering such securities proposed to be sold,
     transferred or otherwise disposed of, describing the manner and terms of
     the proposed sale, transfer or other disposition, and containing a current
     prospectus, is filed with the SEC and made effective under the Securities
     Act; 

          (d)    an authorized representative of the SEC shall have rendered
     written advice to SAIC (sought by SAIC or counsel to the undersigned SAIC,
     with a copy thereof and of all other related communications delivered to
     the Company) to the effect that the SEC will take no action, or that the
     staff of the SEC will recommend that the SEC take no action, with respect
     to the proposed offer, sale, exchange, transfer, pledge or other
     disposition if consummated; or


                                      8

<PAGE>

          (e)    all certificates representing such securities deliverable to
     SAIC and any certificates subsequently issued with respect thereto or in
     substitution therefor shall bear a legend that such securities may only be
     sold or disposed of in accordance with (i) the provisions of Rule 144 under
     the Securities Act, (ii) pursuant to an effective Registration Statement or
     (iii) pursuant to an exemption provided by the Securities Act.  The
     Company, at its reasonable discretion, may cause stop transfer orders to be
     placed with its transfer agent with respect to the certificates for such
     securities but not as to the certificates for any part of such securities
     as to which said legend is no longer required.

          4.11   EXCLUSIVE WARRANTIES REGARDING SOFTWARE.  The exclusive 
warranties of SAIC with respect to the Software are: (a) SAIC owns all right, 
title and interest in and to versions 3.5, 3.5.1 and 4.0 of the CMDS software 
program and has the right to sell, transfer and convey it's right, title and 
interest in the same to ODS in accordance with the provisions of this 
Agreement; (b) versions 3.5, 3.5.1 and 4.0 of the CMDS software program are 
otherwise provided "AS IS" except as provided below in Section 4.12; and (c) 
all other Software is provided to the Company "AS IS" with any and all faults 
and with no warranty against title, patent, trademark, copyright, trade 
secret infringement or other infringement of the rights of a third party.  

     To the extent applicable, SCHEDULE 4.11 lists: (i) the software programs 
on the CD-ROMs attached to Exhibit 1.1(a); (ii) the jurisdiction(s) in which 
an application for patent or application for registration of each Software 
program has been made, including the respective application numbers and 
dates; (iii) the jurisdiction(s) in which each Software program has been 
patented or registered, including the respective patent or registration 
numbers and dates; (iv) all material licenses, sublicenses and other 
agreements to which SAIC is a party pertaining to the origin of the Software 
or any component thereof that SAIC has Knowledge of; (v) the material 
licenses, sublicenses and other agreements of which SAIC has Knowledge and to 
which SAIC is a party and pursuant to which any other party is authorized to 
use, exercise, or receive any benefit from the Software; (vi) all parties to 
whom SAIC has delivered copies of source code included in the Software, 
whether pursuant to an escrow arrangement or otherwise, or parties who have 
the right to receive such source code; and (vii) the written assignments 
obtained by SAIC from SAIC consultants and SAIC employees who contributed to 
the creation or development of the Software of any rights they may have with 
respect to such creation or development of the Software. 

     SAIC has not brought any actions or lawsuits alleging (i) infringement 
of the Software or (ii) breach of any license, sublicense or other agreement 
authorizing another party to use the Software.  SAIC has not entered into any 
agreement granting any third party the right to bring infringement actions 
with respect to, or otherwise to enforce rights with respect to, the 
Software. 

     To SAIC's Knowledge, no person has asserted or threatened to assert any 
claims with respect to the Software (i) contesting the right of SAIC or any 
subsidiary of SAIC to use, exercise, sell, license, transfer or dispose of 
the Software or (ii) challenging the ownership, validity or enforceability of 
the Software. 


                                      9

<PAGE>

     To SAIC's Knowledge, no Software is subject to any outstanding order, 
judgment, decree or stipulation related to or restricting in any manner the 
licensing, assignment, transfer or conveyance thereof by SAIC.

     Notwithstanding anything to the contrary stated in or inferred from this 
Agreement, with respect to the Software SAIC makes no representation or 
warranty with respect to infringement nor is any indemnification obligation 
on the part of SAIC to be inferred. 

          4.12   YEAR 2000 COMPLIANCE.  To SAIC's Knowledge and as except as 
set forth on the SAIC Disclosure Schedule, provided that all hardware and 
software products used with the CMDS software program properly exchange date 
data with the CMDS software program, the CMDS software program will (i) 
handle date information before, during, and after January 1, 2000, including 
but not limited to accepting date input, providing date output, and 
performing calculations on dates or portions of dates; (ii) function 
accurately and without interruption before, during, and after January 1, 
2000, without any change in operations associated with the advent of the new 
century; (iii) respond to two-digit year-date input in a way that resolves 
the ambiguity as to century in a disclosed, defined, and predetermined 
manner, and (iv) store and provide output of date information in ways that 
are unambiguous as to century.  Notwithstanding the foregoing, SAIC 
acknowledges and agrees that (i) the CMDS software program does not identify 
or remedy Year 2000 problems in third party systems or other products or 
applications not provided or supplied by the Company and (ii) the CMDS 
software program operates with the date information it receives; thus, if 
incorrect date information is provided by the user, the system or from any 
other external product or other source, this information will be used by the 
CMDS software program as received. The foregoing Year 2000 Warranty of the 
Company shall not apply to Year 2000 problems caused by such external sources.

          4.13   ASSETS OTHER THAN SOFTWARE. The Personal Property is 
provided to the Company "AS IS." Upon consummation of the transactions 
contemplated by this Agreement and all other agreements delivered hereunder, 
the Company will acquire good and marketable title to, and will become the 
legal beneficial owner of, the Personal Property, free and clear of all 
taxes, mortgages, pledges, liens, security interests, encumbrances or charges 
of any kind.  To SAIC's Knowledge, SAIC is not (nor is any other party) in 
material default under, nor does any event, circumstance or situation exist 
which, with the passage of time will cause a default under any material 
lease, Contract, material license or other material agreement relating to or 
constituting any of the Assets under which any person, firm, corporation or 
other entity is or may be entitled to assert any rights against any of the 
Assets.

                                  ARTICLE V
                                          
                                  COVENANTS

          5.1    FURTHER ASSURANCES.

          (a)    Upon the terms and subject to the conditions hereof, each of
     the parties hereto agrees to use commercially reasonable efforts to take or
     cause to be taken all actions and to do or cause to be done all things
     necessary, proper or advisable to 


                                      10

<PAGE>

     consummate the transactions contemplated by this Agreement shall use 
     commercially reasonable efforts to obtain all necessary waivers, 
     consents and approvals and to effect all necessary registrations and 
     filings to be obtained in connection with the transactions 
     contemplated by this Agreement.

          (b)    In the event SAIC or the Company, as the case may be, is
     unable to obtain, prior to the Closing, any consents, approvals, waivers or
     other authorizations to transfer to the Company any Asset, SAIC and the
     Company will cooperate with each other in order to obtain such consents,
     approvals, waivers or other authorizations at the earliest practicable
     date.  In each instance where such consents, approvals, waivers or other
     authorizations cannot be obtained prior to the Closing, SAIC shall use
     commercially reasonable efforts to enter into such alternative arrangements
     and agreements with the Company as may be appropriate in order to permit
     the Company to realize, receive and enjoy substantially similar rights and
     benefits and to enable the Company utilize the Assets as proposed until the
     consents, approvals, waivers or other authorizations are obtained.  If,
     after the exercise of diligent effort, any such consents, approvals,
     waivers or other authorizations are not obtained, SAIC agrees to cooperate
     with the Company in any reasonable arrangements designed to provide, to the
     extent reasonably practicable, for the benefit of the Company any and all
     rights of SAIC in and to such asset. Nothing in this Section 5.1(b) shall
     be construed to be a waiver by the Company of any condition set forth in
     Article VII.

          (c)    SAIC shall provide the Company with all reasonably requested
     and available information in order for the Company to pursue or defend the
     Company's rights to the Assets.

          5.2    PRESERVATION OF RECORDS.  After the Closing, both parties 
agree to preserve such books, records and filings relating to the Assets as 
may be appropriate or required by applicable law.

          5.3    EMPLOYMENT OF SAIC PERSONNEL.

          (a)    SAIC agrees that the Company may, but is not hereby obligated
     to, solicit for employment and hire the personnel identified on SCHEDULE
     5.3 (a) hereto and SAIC agrees to provide commercially reasonable
     assistance to the Company in such solicitation and hiring.

          (b)    Except as provided herein, all SAIC employees who accept the
     employment offer of the Company ("TRANSFERRED PERSONNEL") shall be subject
     to the terms and conditions of employment that the Company has with
     employees in comparable positions.  The Company represents and warrants
     that it will provide to each of the Transferred Personnel compensation and
     benefits, taken as a whole, that will be substantially comparable to, or
     greater than, the compensation and benefits such Transferred Personnel were
     receiving from SAIC immediately preceding their employment by the Company. 
     During the first eighteen (18) months of the employment of any Transferred
     Personnel, no such Transferred Personnel shall be subject to 


                                      11

<PAGE>

     relocation outside of San Diego County California unless such Transferred 
     Personnel agrees to such relocation.  The Company agrees to provide all 
     Transferred Personnel with stock options or other stock-based incentive 
     compensation.  

          (c)    Only with respect to the Software, SAIC hereby transfers and
     assigns to the Company the rights of SAIC, if any, with respect to any
     employees or consultants of SAIC  who authored any of the Software
     including, but not limited to the rights of SAIC  under any SAIC Invention,
     Copyright and Confidentiality Agreement between SAIC and any employees  but
     only as the SAIC Invention, Copyright and Confidentiality Agreement
     pertains to the Software; provided, however, that any such personnel will
     not be encouraged or requested by the Company to make any disclosure of the
     identity of licensees of the Software that have not been disclosed to the
     Company by SAIC or with respect to matters that are not directly related to
     the Software.  Notwithstanding the foregoing, the parties agree that SAIC
     shall retain the right to freely use for any purpose the residuals
     resulting from access to or work with the Software, provided such residuals
     will not be used to create computer programs that perform substantially the
     same functions in substantially the same way, to achieve the same or
     substantially the same result as the Software.  The term "residuals" means
     technical information related to the Software in non-tangible form, which
     may be retained by persons who have had access to the Software, including
     ideas, concepts, know-how, or techniques contained therein. Neither party
     shall have any obligation to limit or restrict the assignment of such
     persons or to pay royalties for any work resulting from the use of
     residuals. Nothing in the foregoing shall, however, be deemed to be the
     grant of a license under the copyrights and patent application conveyed
     under this Agreement.

          (d)    For a period of five (5) years from the date of this
     Agreement, the Company shall notify SAIC of the termination of the
     employment by the Company or its successors or assigns of any Transferred
     Personnel ("TERMINATION OF EMPLOYMENT"), no matter what the reason was for
     the Termination of Employment. Such notice shall be sent to the attention
     of SAIC's Stock Programs Department, Attention: Karen Grasson, 10260 Campus
     Point Drive, M/S F3, San Diego, CA 92121, within ten (10) days after the
     date of the Termination of Employment and shall state the date of the
     Termination of Employment and last known address, home telephone number and
     e-mail address (if known by the Company) of such Transferred Personnel.  If
     the Termination of Employment was due to death or disability of the

                        ODS NETWORKS AND SAIC JOIN FORCES
                           IN NETWORK SECURITY MARKET

                   -- ODS Acquires the CMDS Assets of SAIC and
             SAIC Obtains Right to Acquire up to 16% of ODS' Common
Shares --


RICHARDSON, Texas, September 28, 1998 - ODS Networks, Inc. (NASDAQ: ODSI), a 
leading provider of enterprise-wide information security and switched network 
solutions, today announced it has acquired certain assets of the CMDS 
(Computer Misuse and Detection System) Division of Science Applications 
International Corporation (SAIC) and certain other information security 
products under development. In addition, SAIC's Chief Financial Officer, 
William A. Roper, has joined ODS' Board of Directors.

This acquisition represents a key component of ODS Network's strategy to 
provide the most comprehensive security portfolio in the industry. CMDS has 
developed one of the industry's most advanced software tools for host-based 
intrusion detection, data forensics and audit management.

In exchange for the CMDS assets, the information security products under 
development and $1,500,000 in cash, ODS issued to SAIC 1,600,000 shares of 
its common stock and warrants to purchase 1,500,000 shares of its common 
stock. Two separate warrants each grant SAIC the right to purchase 750,000 
shares of ODS common stock. The first warrant has an exercise price of $8.00 
per share and a term of 18 months. The second warrant has an exercise price 
of $10.50 per share and a term of 24 months. Based on the closing price of 
ODS common stock on the Nasdaq National Market on September 25, 1998, the 
transaction is valued at approximately $6,600,000. ODS' acquisition will be 
accounted for as a purchase of software and in-process technology.

As part of the strategic relationship, ODS will be a preferred partner for 
certain other information security products developed by SAIC in the future, 
and SAIC will become a value added reseller of ODS products including ODS 
Network's award-winning CryptoCom(tm), SecureCom(tm) , InfiniteSwitch(tm) and 
LanBlazer(tm) product families.


                    Deal Solidifies ODS' Comprehensive Security Arsenal David 
Drake was elected by ODS' Board of Directors as a vice president of ODS and 
now heads the newly formed division. Additionally, about 20 professional 
staff members, including experienced security engineers, 

<PAGE>

located in San Diego, California, are now part of ODS.

According to a Yankee Group report from June 1998, the market for intrusion 
detection and security assessment was $45 million in 1997, and is expected to 
grow to more than $300 million in 1999 and $747 million in 2003. The report 
also noted that intrusion detection and security assessment systems 
complement firewalls, encryption and authentication systems and are integral 
components of an effective network security policy.

"Customers want a comprehensive information security solution. The 
combination of CMDS with ODS' SecureCom and CryptoCom security products will 
give ODS one of the most complete network security solutions in the 
industry," stated G. Ward Paxton, chairman, president, and CEO of ODS 
Networks. "In addition, our strategic relationship with SAIC provides us with 
an important channel for our products and future access to valuable 
technology and resources," added Paxton.

"This strategic business relationship with ODS gives SAIC a vehicle to 
realize financial returns for network security products and technology 
developed by SAIC," said Steve Manning, vice president of the Center for 
Information Security Technology at SAIC. "Our investment in ODS is a sign of 
our commitment to the future working relationship with them," concluded 
Manning.

About CMDS

SAIC has developed one of the industry's most advanced software tools for 
host-based intrusion detection, data forensics and audit management to 
protect an organization's information assets from security threats. CMDS is a 
software program that detects misuse by analyzing audit data that is 
generated from operating systems, databases and application programs, as well 
as network-related devices installed within an enterprise. Unlike other 
intrusion and computer misuse detection products, CMDS uses an integrated 
expert system to analyze and correlate the massive amounts of data necessary 
to highlight subtle changes in authorized user behavior that can indicate 
data theft or socially engineered attacks. CMDS can simultaneously track tens 
of thousands of users of any sized network from the smallest bank branch to 
the largest networks, far beyond the capabilities of even the largest and 
most sophisticated security staffs.

The CMDS product is highly complementary to ODS' SecureCom and CryptoCom 
families. Together, these products enable organizations to perform 
comprehensive analyses of their network security systems to identify and 
correct weaknesses in their current system configurations, to monitor the 
network and audit data for suspicious activities, and to quickly respond to 
potential security breaches.

             ODS NETWORKS ACQUIRES NEW PRODUCTS FOR THE COMPUTER
                 MISUSE/INTRUSION DETECTION MARKET FROM SAIC
                                      
         -ODS NETWORKS AND SAIC TEAM IN THE COMPUTER SECURITY MARKET-

RICHARDSON, Texas, September 28, 1998 - ODS Networks, Inc., (NASDAQ:ODSI), a 
leading supplier of secure and high speed networking, today announced that it 
has acquired the Computer Misuse and Detection System (CMDS) and certain 
other intellectual property from Science Applications International 
Corporation (SAIC), and announced that ODS will incorporate CMDS into its 
"Hardened Networks" security architecture.

CMDS SOLVES "INSIDER PROBLEM"

CMDS is the first misuse and intrusion detection system to completely solve 
the "INSIDER PROBLEM," while also protecting against hacker threats.  
According to Matthew Kovar, Senior Data Security Analyst with Yankee Group,  
"70 percent of security incidents involve insider theft of confidential data, 
damage by disgruntled employees and misuse of computer resources." CMDS is 
designed to protect critical network devices such as servers, hosts, 
firewalls and data repositories.  Unlike other intrusion and computer misuse 
detection products, CMDS uses an integrated expert system to analyze and 
correlate the massive amounts of data necessary to highlight subtle changes 
in authorized user behavior that can indicate data theft or socially 
engineered attacks.  The CMDS approach solves both the insider problem and 
detects intruders who manage to thwart network perimeter defenses.

The CMDS reporting engine can produce a wide range of management reports and 
graphs to any level of detail required.  The security administrator can 
accurately track system use to security policy requirements as well as 
highlight areas of deficiency.

The difficulty with misuse detection is that trusted users have authorization 
to use shared systems like servers and hosts.  Distinguishing between "normal 
use" and "misuse" requires on-going analysis and correlation of massive 
amounts of data. With CMDS, user behavior is automatically analyzed based on 
historical usage patterns and also compared against peer group behavior.  Any 
significant change in a user's behavior like daytime and nighttime activity, 
increases in file browsing, program executions or failed logins is 
automatically correlated and tracked.  Without the CMDS approach, there is no 
practical way to analyze misuse data to find a data thief.  CMDS can be 
configured to warn, alert or increase its surveillance of the user for 
developing a prosecution file.  

ODS OFFERS HARDENED NETWORKS

With the CMDS product addition, ODS Networks offers the unique seven-layer 
"Hardened Networks" framework for security administrators in the commercial 
and government markets. The Hardened Networks architecture encompasses a mesh 
of threat detection and elimination technologies that focus on the enterprise 
security infrastructure instead of the "just the network perimeter" concept 
touted by most security vendors. "Very few security vendors are focused on 
the whole security problem," said G. Ward Paxton, chairman, president, and 
CEO of ODS Networks. "Our product strategy is designed to catch both insider 
and external threats. With the ODS Hardened Networks product architecture, we 
provide superior protection through layers of defense.  No other vendor has 
the breadth of products to match our capability."

ABOUT CMDS

CMDS supports most major host and network operating systems, including UNIX 
and Windows NT.  CMDS for Firewalls also supports Raptor, Cyberguard and 
Interlock. Server agent prices start at $995.00 for UNIX servers and $795.00

requested to be included in such registration and (ii) the intended method of 
distribution of such shares.  The Company will promptly give notice of such 
requested registration to all other Holders of Registrable Stock and, subject 
to Section 2.1(c), will include in such registration all shares of 
Registrable Stock that Holders of Registrable Stock have requested the 
Company to include in such registration by notice to the Company within 
20 days after the date of receipt of the Company's notice.

               (c)  If the Holders initiating a Registration Request intend 
to distribute the Registrable Stock covered by such request by means of an 
Underwritten Offering, then such Holders shall so advise the Company as a 
part of their Registration Request and the Company shall include such 
information in the written notice referred to in SECTION 2.1(b).  In such 
event, the right of the Holders to include their Registrable Stock in such 
registration shall be conditioned upon the Holders participation in such 
underwriting and the inclusion of the Holders' Registrable Stock in the 
underwriting.  Any Registrable Stock excluded and withdrawn from such 
underwriting shall be withdrawn from the registration.  Notwithstanding any 
other provision of this Agreement, if the managing underwriter determines in 
good faith that marketing factors require a limitation of the number of 
shares to be underwritten, then the managing underwriter may exclude shares 
(including Registrable Stock) from the registration and the underwriting, and 
the number of shares that may be included in the registration and the 
underwriting shall be allocated, FIRST, pro rata among the Holders of 
Registrable Stock requesting to be included in such registration on the basis 
of the number of shares that such Holders have requested be included in the 
registration, SECOND, to the Company, THIRD, pro rata among all other 
security holders having contractual rights to include their securities in 
such registration on the basis of the number of shares that such holders have 
requested to be included in the registration, and FOURTH, to all other 
security holders requesting to include securities in such registration.

          2.2  SELECTION OF MANAGING UNDERWRITER(S).  The Company will have 
the right to select one or more nationally recognized underwriters to manage 
any offering which is the subject of a Demand Registration that is intended 
to be an Underwritten Offering.

          2.3  RIGHT TO DEFER REGISTRATION.  No Registration Request shall 
require a Registration Statement requested therein to be filed (i) prior to 
the effective date of a registration statement filed by the Company covering 
an Underwritten Offering of Common Stock if the Company shall have given 
written notice in the manner provided in SECTION 2.4 below of such 
Registration Statement to the Holders prior to the receipt of a Registration 
Request and shall have thereafter pursued the preparation, filing and 
effectiveness of such registration statement with diligence (it being 
understood by such Holders that advance notice of the pendency of such 
registration may be material, non-public information) or (ii) if the Company 
shall furnish to the Holders a certificate signed by the Chairman of the 
Board of the Company stating that, in the good faith judgment of the Board of 
Directors of the Company, it would be seriously detrimental to the Company 
and its stockholders for such registration to be effected at such time, in 
which 

<PAGE>

event the Company shall have the right to defer the filing of the 
Registration Statement for a period of not more than sixty (60) days after 
receipt of the Registration Request.  If the Company shall so postpone the 
filing of a Registration Statement, such Holders of Registrable Stock 
requesting registration thereof pursuant to SECTION 2.1 shall have the right 
to withdraw the request for registration by giving written notice to the 
Company within thirty (30) days after receipt of the notice of postponement 
and, in the event of such withdrawal, such request shall not count as the 
request for registration to which Holders of Registrable Stock are entitled 
pursuant to SECTION 2.1 hereof.  Any registration requested pursuant to 
SECTION 2.1 shall not be deemed to have been effected (i) unless the 
Registration Statement with respect thereto has become effective, (ii) if 
after it has become effective and prior to the sale of all of the Registrable 
Stock covered thereby, such registration is interfered with by any stop 
order, injunction or other order or requirement of the Commission or other 
governmental agency or court for any reason not attributable to the selling 
Holders and has not thereafter become effective, or (iii) if the conditions 
to closing specified in the underwriting agreement, if any, entered into in 
connection with such registration are not satisfied or waived, other than by 
reason of a failure on the part of the selling Holders.

          2.4  PIGGYBACK REGISTRATIONS.

               (a)  RIGHT TO PIGGYBACK.  If, after the first anniversary of 
the Closing Date, the Company proposes to register any offering of its 
securities under the Securities Act, whether or not for sale for its own 
account (other than pursuant to a Demand Registration or on Form S-4, Form S-8 
or any successor form), and the registration form to be used permits the 
registration of an offering of Registrable Stock by the Holders (a "PIGGYBACK 
REGISTRATION"), the Company will give prompt notice to all Holders of 
Registrable Stock of its intention to effect such a registration (each a 
"PIGGYBACK NOTICE").  Subject to SECTION 2.4(b) below, the Company will 
include in such registration all shares of Registrable Stock that the Holders 
thereof have requested the Company to include in such registration by notice 
to the Company within 20 days after the date of receipt of the Company's 
notice.  No such registration effected under this SECTION 2.4 shall relieve 
the Company of its obligation to effect any registration upon request under 
SECTION 2.1.

               (b)  PRIORITY ON PRIMARY REGISTRATIONS.  If any Piggyback 
Registration shall be an Underwritten Offering, the right of any such 
Holder's Registrable Stock to be included in such Piggyback Registration 
shall be conditioned upon such Holder's participation in such underwriting 
and the inclusion of such Holder's Registrable Stock in the underwriting to 
the extent provided herein.  Notwithstanding any other provision of this 
Agreement, if the managing underwriter determines in good faith that 
marketing factors require a limitation of the number of shares to be 
underwritten, then the managing underwriter may exclude shares (including 
Registrable Stock) from the registration and the underwriting, and the number 
of shares that may be included in the registration and the underwriting shall 
be allocated, FIRST, to the Company, SECOND, pro rata among all security 
holders having contractual rights to include their securities in such 
registration (including the Holders) on the basis of the number of shares 
that such holders have requested (consistent with their contractual rights) 
to be included in the registration, and THIRD, to all other security holders 
requesting to include securities in such registration. If any Holder 
disapproves of the terms of any such underwriting, such Holder may elect to 
withdraw therefrom by written notice to the Company and the managing 
underwriter.  Any Registrable 

<PAGE>

Stock excluded or withdrawn from such underwriting shall be excluded and 
withdrawn from the registration.

          2.5  REGISTRATION PROCEDURES.  In connection with any registration 
hereunder, the Company will use its best efforts to effect the registration 
and the sale of such Registrable Stock in accordance with the intended method 
of distribution thereof and will as expeditiously as possible:

               (a)  prepare and file with the Commission, a Registration 
Statement on Form S-3 (or if the Company is not then eligible to register for 
resale the Registrable Stock on Form S-3 such registration shall be on 
another appropriate form) which shall contain a "Plan of Distribution" in the 
form (which shall be reasonable and customary) to be supplied to the Company 
in writing by the selling Holders, and use its best efforts to cause the 
Registration Statement to become effective and remain effective as provided 
herein; PROVIDED, HOWEVER, that within a reasonable period prior to the 
filing of the Registration Statement or any related Prospectus or any 
amendment or supplement thereto, the Company shall furnish to the Holders, 
the Special Counsel and any managing underwriters, copies of all such 
documents proposed to be filed, which documents will be subject to the 
reasonable comments of such Holders, the Special Counsel and such managing 
underwriters.  The Company shall not file the Registration Statement or any 
such Prospectus or any amendments or supplements thereto to which the Holders 
of a majority of the Registrable Stock, their Special Counsel, or any 
managing underwriters, shall reasonably object on a timely basis;

               (b)  (i) prepare and file with the Commission such amendments 
and post-effective amendments to such Registration Statement as may be 
necessary to keep such Registration Statement effective for such period as 
shall be required for the disposition pursuant to the terms of such 
registration of all Registrable Stock covered thereby (but not to exceed, in 
the case of: (A) any Demand Registration (if not a Shelf Registration) or any 
Piggyback Registration, 60 days PLUS any additional periods represented by 
any "BLACK-OUT PERIOD" (as defined in the last paragraph of this SECTION 2.5) 
or (B) any Demand Registration (if a Shelf Registration), the first 
anniversary of the effective date of such registration PLUS any additional 
periods represented by any Black-Out Period), (ii) cause the related 
Prospectus to be amended or supplemented by any required Prospectus 
supplement, and as so supplemented or amended to be filed pursuant to Rule 424 
(or any similar provisions then in force) promulgated under the Securities 
Act; (iii) respond as promptly as reasonably possible to any comments 
received from the Commission with respect to the Registration Statement or 
any amendment thereto and as promptly as reasonably possible provide the 
Holders true and complete copies of all correspondence from and to the 
Commission relating to the Registration Statement; and (iv) comply with the 
provisions of the Securities Act with respect to the disposition of all 
Registrable Stock covered by the Registration Statement during the applicable 
period in accordance with the intended methods of distribution by the Holders 
thereof set forth in the Registration Statement as so amended or in such 
Prospectus as so supplemented;

               (c)  furnish to each Holder, the Special Counsel and any 
managing underwriters, without charge, at least one conformed copy of each 
Registration Statement and each amendment thereto, including financial 
statements and schedules, all documents incorporated or deemed to be 
incorporated therein by reference, and all exhibits to the extent 

<PAGE>

requested by such Person (including those previously furnished or 
incorporated by reference) promptly after the filing of such documents with 
the Commission;

               (d)  deliver to each Holder, the Special Counsel, and any 
underwriters, without charge, as many copies of the Prospectus or 
Prospectuses (including each form of Prospectus) and each amendment or 
supplement thereto as such Persons may reasonably request in order to 
facilitate the disposition of the Registrable Stock proposed to be sold;

               (e)  use its best efforts to register or qualify or cooperate 
with the selling Holders, any underwriters or its Special Counsel in 
connection with the registration or qualification (or exemption from such 
registration or qualification) of such Registrable Stock for offer and sale 
under such other securities or blue sky laws of such jurisdictions as any 
Holder or underwriter reasonably requests to keep such registration or 
qualification (or exemption therefrom) in effect for as long as the relevant 
Registration Statement is in effect and do any and all other acts and things 
which may be reasonably necessary or advisable to enable such Holder to 
consummate the disposition in such jurisdictions of the Registrable Stock 
proposed to be sold by such Holder; PROVIDED, HOWEVER, that the Company will 
not be required (i) to qualify generally to do business in any jurisdiction 
where it would not otherwise be required to qualify but for this SUBSECTION (e) 
or (ii) to consent to general service of process in any such jurisdiction;

               (f)  notify each Holder of such Registrable Stock, at any time 
when a Prospectus relating thereto is required to be delivered under the 
Securities Act, of the happening of any event as a result of which the 
Prospectus included in such Registration Statement contains an untrue 
statement of a material fact or omits any fact necessary to make the 
statements therein not misleading and, at the request of any such Holder, the 
Company will promptly prepare a supplement or amendment to such Prospectus so 
that, as thereafter delivered to the purchasers of such Registrable Stock, 
such Prospectus will not contain an untrue statement of a material fact or 
omit to state any fact necessary to make the statements therein, in light of 
the circumstances under which such statements are made, not misleading;

               (g)  cause all such Registrable Stock to be listed on each 
securities exchange on which similar securities issued by the Company are 
then listed and to be qualified for trading on each system on which similar 
securities issued by the Company are from time to time qualified;

               (h)  provide a transfer agent and registrar for all such 
Registrable Stock not later than the effective date of such Registration 
Statement and thereafter maintain such a transfer agent and registrar;

               (i)  cooperate with the Holders and any managing underwriters 
to facilitate the timely preparation and delivery of certificates 
representing Registrable Stock to be delivered to a transferee pursuant to a 
Registration Statement, which certificates shall be free, to the extent 
permitted by applicable law, of all restrictive legends, and to enable such 
Registrable Stock to be in such denominations and registered in such names as 
any such managing underwriters or Holders may request at least two Business 
Days prior to any sale of Registrable Stock;

<PAGE>

               (j)  in the case of any Underwritten Offering, enter into such 
customary agreements (including an underwriting agreement in form, scope and 
substance as is customary in Underwritten Offerings) and take all such other 
reasonable actions in connection therewith (including those reasonably 
requested by any managing underwriters and the Holders of a majority of the 
Registrable Stock being sold) in order to expedite or facilitate the 
disposition of such Registrable Stock, and (i) make such representations and 
warranties to such Holders and such underwriters as are customarily made by 
issuers in Underwritten Offerings; (ii) obtain and deliver copies thereof to 
each Holder and the managing underwriters, if any, of opinions of counsel to 
the Company and updates thereof addressed to each Holder and each such 
underwriter, in form, scope and substance reasonably satisfactory to any such 
managing underwriters and Special Counsel to the selling Holders covering the 
matters customarily covered in opinions requested in Underwritten Offerings; 
(iii) immediately prior to the effectiveness of the Registration Statement, 
and at the time of delivery of any Registrable Stock sold pursuant thereto, 
obtain and deliver copies to the Holders and the managing underwriters, if 
any, of "cold comfort" letters and updates thereof from the independent 
certified public accountants of the Company (and, if necessary, any other 
independent certified public accountants of any subsidiary of the Company or 
of any business acquired by the Company for which financial statements and 
financial data is, or is required to be, included in the Registration 
Statement), addressed to the Company in form and substance as are customary 
in connection with Underwritten Offerings; and (iv) if an underwriting 
agreement is entered into, the same shall contain indemnification provisions 
and procedures no less favorable to the selling Holders than those set forth 
in ARTICLE III hereof (or such other provisions and procedures acceptable to 
the holders of a majority of Registrable Stock participating in such 
Underwritten Offering);

               (k)  make available for inspection by the selling Holders, any 
representative of such Holders, any underwriter participating in any 
disposition of Registrable Stock, and any attorney or accountant retained by 
such selling Holders or underwriters, at the offices where normally kept, 
during reasonable business hours, all financial and other records, pertinent 
corporate documents and properties of the Company and its subsidiaries, and 
cause the officers, directors, agents and employees of the Company and its 
subsidiaries to supply all information reasonably requested by any such 
Holder, representative, underwriter, attorney, accountant or agent in 
connection with such Registration Statement;

               (l)  otherwise use its best efforts to comply with all 
applicable rules and regulations of the Commission, and make available to its 
security holders, as soon as reasonably practicable, an earnings statement 
covering the period of at least 12 months beginning with the first day of the 
Company's first full calendar quarter after the effective date of the 
Registration Statement, which earnings statement shall satisfy the provisions 
of Section 11(a) of the Securities Act and Rule 158 thereunder;

                 (m)  notify the Holders of Registrable Stock to be sold, the 
Special Counsel and any managing underwriters as promptly as reasonably 
possible when: (i)(A) a Prospectus or any Prospectus supplement or 
post-effective amendment to the Registration Statement is proposed to be 
filed; (B) when the Commission notifies the Company whether there will be a 
"review" of such Registration Statement and whenever the Commission comments 
in writing on such Registration Statement (the Company shall provide true and 
complete copies thereof and all written responses thereto to each of the 
selling Holders); and (C) with respect to 

<PAGE>

the Registration Statement or any post-effective amendment, when the same has 
become effective; (ii) of any request by the Commission or any state 
governmental authority for amendments or supplements to the Registration 
Statement or Prospectus or for additional information; (iii) of the issuance 
by the Commission of any stop order suspending the effectiveness of the 
Registration Statement or the initiation of any Proceedings for that purpose; 
(iv) if at any time any of the representations and warranties of the Company 
contained in any agreement (including any underwriting agreement) 
contemplated hereby ceases to be true and correct in all material respects; 
(v) of the receipt by the Company of any notification with respect to the 
suspension of the qualification or exemption from qualification of any of the 
Registrable Stock for sale in any jurisdiction, or the initiation or 
threatening of any Proceeding for such purpose; and (vi) of the occurrence of 
any event that requires any revisions to the Registration Statement, 
Prospectus or any document incorporated therein by reference so that, in the 
case of the Registration Statement or the Prospectus, as the case may be, it 
will not contain any untrue statement of a material fact or omit to state any 
material fact required to be stated therein or necessary to make the 
statements therein, in light of the circumstances under which they were made, 
not misleading.

Each Holder of shares covered by a Registration Statement agrees that if the 
Company has delivered preliminary or final Prospectuses to such Holder and 
after having done so the Company shall give notice to such Holder that (i) the 
Prospectus needs to be amended or supplemented to comply with the 
requirements of the Securities Act, (ii) a stop order suspending the 
effectiveness of the Registration Statement is issued by the Commission or 
(iii) a Potential Material Event shall exist, then each such Holder shall 
immediately cease making offers and sales of Registrable Stock and return all 
remaining Prospectuses to the Company.  Following such amendment or 
supplement, the lifting of any stop order or such time as the Potential 
Material Event shall no longer exist, the Company shall promptly provide such 
Holders with revised Prospectuses and, following receipt of the revised 
Prospectuses, such Holders shall be free to resume making offers of the 
Registrable Stock, or any portion thereof.  The period during which the 
Company exercises its rights as described in this paragraph to postpone, 
delay or interrupt the offer and sale of the Registrable Stock (which may not 
exceed 90 days during any twelve-month period) or during the pendency of any 
stop order, injunction or other order or requirement of the Commission or any 
other governmental agency or court shall be referred to herein as a 
"BLACK-OUT PERIOD."

          2.6  PAYMENT OF EXPENSES.  The Company shall pay all Registration 
Expenses in connection with any Demand Registration and any Piggyback 
Registration.

          2.7  PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.  No Holder may 
participate in any registration hereunder which is underwritten unless such 
Holder (a) agrees to sell such Holder's securities on the basis provided in 
any underwriting arrangements approved by the Person or Persons entitled 
hereunder to approve such arrangements; (b) completes and executes all 
questionnaires, powers of attorney, indemnities, standstill or holdback 
agreements, underwriting agreements and other documents required under the 
terms of such underwriting arrangements; and (c) if requested by the managing 
underwriter, agrees not to sell or otherwise dispose of Registrable Stock or 
other Company securities held by such Holder in any transaction other than 
pursuant to such underwriting for such period (not to exceed 180 days) as 
determined in the discretion of the Board of Directors of the Company (such 
agreement to be in writing in a 

<PAGE>

form satisfactory to the Company and such managing underwriter), PROVIDED, 
that no Holder of Registrable Stock shall be required to enter into such an 
agreement unless each other Holder of Registrable Stock participating in such 
offering enters into a substantially identical agreement relating to such 
underwriting. The Company may impose stop-transfer instructions to its 
transfer agent with respect to the Registrable Stock and other securities 
subject to the restriction described in clause (c) above until the end of the 
lock-up period.

          2.8  INFORMATION OF THE HOLDERS.  As a condition to participation 
in any registration hereunder, each Holder shall furnish to the Company such 
information regarding such Holder and the distribution proposed by the Holder 
as the Company may reasonably request and as shall be required in connection 
with any registration, qualification or compliance contemplated by this 
Agreement.

          2.9  RULE 144 INFORMATION.  From and after the first anniversary of 
the Closing Date and for so long as necessary in order to permit the Holders 
to sell the Registrable Stock pursuant to Rule 144 under the Securities Act, 
the Company will file on a timely basis all reports required to be filed by 
it pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, 
referred to in paragraph (c)(1) of Rule 144 under the Securities Act (or, if 
applicable, the Company will make publicly available the information 
regarding itself referred to in paragraph (c)(2) of Rule 144), in order to 
permit the Holders to sell the Registrable Stock, pursuant to the terms and 
conditions of the applicable provisions of Rule 144.

                                 ARTICLE III
                               INDEMNIFICATION

          3.1  INDEMNIFICATION BY THE COMPANY.  The Company agrees to 
indemnify, to the extent permitted by law, each Holder, its officers and 
directors and each Person who controls such Holder (within the meaning of the 
Securities Act) against all losses, claims, damages, liabilities and expenses 
caused by any untrue or alleged untrue statement of material fact contained 
in any Registration Statement, Prospectus or preliminary Prospectus or any 
amendment thereof or supplement thereto or any omission or alleged omission 
of a material fact required to be stated therein or necessary to make the 
statements therein not misleading, except insofar as the same are caused by 
or contained in any information furnished in writing to the Company by such 
Holder, its officers and directors and each Person who controls such Holder 
expressly for use therein or by such Holder's failure to deliver a copy of 
the Registration Statement or Prospectus or any amendments or supplements 
thereto after the Company has furnished such Holder with a sufficient number 
of copies of the same.

          3.2  INDEMNIFICATION BY HOLDERS.  In connection with any 
Registration Statement in which a Holder is participating, each such Holder 
will, to the extent permitted by law, indemnify the Company, its directors 
and officers and each Person who controls the Company (within the meaning of 
the Securities Act) against any losses, claims, damages, liabilities and 
expenses resulting from any untrue or alleged untrue statement of material 
fact contained in the Registration Statement, Prospectus or preliminary 
Prospectus or any amendment thereof or supplement thereto or any omission or 
alleged omission of a material fact required to be stated therein or 
necessary to make the statements therein not misleading (but only to the 
extent that such untrue statement or omission is contained in any information 
furnished in 

<PAGE>

writing by such Holder expressly for use therein) and any failure by each 
such Holder to deliver a copy of the Registration Statement or Prospectus or 
any amendments or supplements thereto after the Company has furnished such 
Holder with a sufficient number of copies of the same.

          3.3  NOTICE: DEFENSE OF CLAIMS.  Any Person entitled to 
indemnification hereunder will (a) give prompt written notice to the 
indemnifying party of any claim with respect to which it seeks 
indemnification and (b) unless in such indemnified party's reasonable 
judgment a conflict of interest between such indemnified and indemnifying 
parties may exist with respect to such claim, permit such indemnifying party 
to assume the defense of such claim with counsel reasonably satisfactory to 
the indemnified party.  If such defense is assumed, the indemnifying party 
will not be subject to any liability for any settlement made by the 
indemnified party without its consent (but such consent will not be 
unreasonably withheld).  An indemnifying party who is not entitled to, or 
elects not to, assume the defense of a claim will not be obligated to pay the 
fees and expenses of more than one counsel (in addition to local counsel) for 
all parties indemnified by such indemnifying party with respect to such 
claim, unless in the reasonable judgment of any indemnified party a conflict 
of interest may exist between such indemnified party and any other of such 
indemnified parties with respect to such claim.

          3.4  CONTRIBUTION.  If the indemnification provided for in this 
ARTICLE III is unavailable or insufficient to hold harmless an indemnified 
party under SECTION 3.1 or 3.2, then each indemnifying party shall contribute 
to the amount paid or payable by such indemnified party as a result of the 
losses, claims, damages or liabilities referred to above (a) in such 
proportion as is appropriate to reflect the relative benefits received by the 
indemnifying party on the one hand and the indemnified party on the other 
from the offering of the securities or (b) if the allocation provided by 
clause (a) above is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only the relative benefits referred to in clause (a) 
above but also the relative fault of the indemnifying party on the one hand 
and the indemnified party on the other in connection with the statements or 
omissions that resulted in such losses, claims, damages or liabilities, as 
well as any other equitable considerations.  The relative benefits received 
by the indemnifying party on the one hand and the indemnified party on the 
other shall be deemed to be in the same proportion as the total net proceeds 
from the offering received by the indemnifying party bear to the total net 
proceeds received by the indemnified party.  The relative fault shall be 
determined by reference to, among other things, whether the untrue or alleged 
untrue statement of a material fact or the omission or alleged omission to 
state a material fact related to information supplied by the indemnifying 
party or written information supplied by indemnified party, and the parties' 
relevant intent, knowledge, access to information and opportunity to correct 
or prevent such untrue statement or omission.  The amount paid by an 
indemnified party as a result of the losses, claims, damages or liabilities 
referred to in the first sentence of this SECTION 3.4 shall be deemed to 
include any legal or other expenses reasonably incurred by such indemnified 
party in connection with investigating or defending against any action or 
claim that is the subject of this section.  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.  Any obligation of a Holder to provide 
contribution will be individual to such Holder and will be limited to the net 
amount of proceeds received by such Holder from the sale of Registrable Stock 
that is the subject of any claim.

<PAGE>

          3.5  SURVIVAL.  The indemnification provided for under this 
Agreement will remain in full force and effect regardless of any 
investigation made by or on behalf of the indemnified party or any officer, 
director or controlling Person of such indemnified party and will survive the 
transfer of securities.

                                  ARTICLE IV

     This certifies that, for value received, SCIENCE APPLICATIONS 
INTERNATIONAL CORPORATION, a Delaware corporation ("SAIC"), or registered 
assigns (the "HOLDER"), during the term of this Warrant as set forth in 
SECTION 1, is entitled to purchase from ODS NETWORKS, INC., a Delaware 
corporation (the "COMPANY"), for value received, shares of the Common Stock 
of the Company, $0.01 par value (the "COMMON STOCK"), in the amount set forth 
in SECTION 2, upon surrender hereof, at the principal office of the Company 
referred to below, with a duly executed Notice of Exercise in the form 
attached, and simultaneous payment therefor in lawful money of the United 
States, at the Exercise Price set forth in SECTION 3.  The number, character 
and Exercise Price of such shares of Common Stock are subject to adjustment 
as provided below.  The term "Warrant" as used herein shall include this 
Warrant, and any warrants delivered in substitution or exchange therefor as 
provided herein.

     1.   TERM OF WARRANT.  Subject to the terms and conditions set forth 
herein, this Warrant shall be exercisable, in whole or in part, at any time 
or from time to time before 5:00 p.m., on March 25, 2000.  After such date,

     4.   EXERCISE OF WARRANT.


                                     -1-

<PAGE>

          (1)  METHOD OF EXERCISE.  The purchase rights represented by this
     Warrant are exercisable by the Holder in whole or in part, at any time, or
     from time to time, during the term hereof as described in SECTION 1 above,
     by the surrender of this Warrant and delivery of the Notice of Exercise
     annexed hereto duly completed and executed on behalf of the Holder, at the
     office of the Company, and upon payment equal to the product of the
     Exercise Price multiplied by the number of shares designated by the Holder
     in the Notice of Exercise in cash or by check payable to the Company.

          (2)  OTHER MATTERS.  This Warrant shall be deemed to have been
     exercised immediately prior to the close of business on the date of its
     surrender for exercise as provided above, and the person entitled to
     receive the shares of Common Stock issuable upon such exercise shall be
     treated for all purposes as the holder of record of such shares as of the
     close of business on such date.  As promptly as practicable on or after
     such date and in any event within ten (10) days thereafter, the Company at
     its expense shall issue and deliver to the person or persons entitled to
     receive the same a certificate or certificates for the number of shares
     issued upon such exercise.  In the event that this Warrant is exercised in
     part, the Company at its expense will execute and deliver a new Warrant of
     like tenor exercisable for the remaining number of shares for which this
     Warrant may then be exercised.

     5.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip 
representing fractional shares shall be issued upon the exercise of this 
Warrant.  In lieu of any fractional share to which the Holder would otherwise 
be entitled, the Company shall make a cash payment equal to the Exercise 
Price multiplied by such fraction.

     6.   REPLACEMENT OF WARRANT.  On receipt of evidence reasonably 
satisfactory to the Company of the loss, theft, destruction or mutilation of 
this Warrant and, in the case of loss, theft or destruction, on delivery of 
an indemnity agreement reasonably satisfactory in form and substance to the 
Company or, in the case of mutilation, on surrender and cancellation of this 
Warrant, the Company at its expense shall execute and deliver, in lieu of 
this Warrant, a new warrant of like tenor and amount.

     7.   NO RIGHTS AS STOCKHOLDER.  This Warrant shall not entitle its 
Holder to any of the rights of a stockholder of the Company.

     8.   TRANSFER OF WARRANT.

          (1)  WARRANT REGISTER.  The Company will maintain a register (the
     "WARRANT REGISTER") containing the names and addresses of the Holder or
     Holders.  Any Holder of this Warrant or any portion thereof may change his
     or her address as shown on the Warrant Register by written notice to the
     Company requesting such change.  Any notice or written communication
     required or permitted to be given to the Holder may be delivered or given
     by mail to such Holder as shown on the Warrant Register and at the address
     shown on the Warrant Register.  Until this Warrant is transferred on the
     Warrant Register of the Company, the Company may treat the Holder as shown
     on the Warrant Register as the absolute owner of this Warrant for all
     purposes, notwithstanding any notice to the contrary.

          (2)  TRANSFERABILITY AND NONNEGOTIABILITY OF WARRANT.  This Warrant
     may not be transferred or assigned in whole or in part without compliance
     with all applicable federal and state securities laws by the transferor and
     the transferee (including the delivery of investment representation letters
     and legal opinions reasonably satisfactory to the Company).  Subject to
     compliance with the foregoing and the Securities Act of 1933, as amended
     (the "ACT"), and applicable state securities laws, title to this Warrant
     may be transferred by endorsement (by the 


                                     -2-

<PAGE>

     Holder executing the Assignment Form annexed hereto) and delivery in 
     the same manner as a negotiable instrument transferable by endorsement 
     and delivery.  The Holder or owner hereof by the taking hereof consents 
     and agrees that any person in possession of this Warrant properly 
     endorsed for transfer to such person (including endorsed in blank) is 
     authorized to represent himself as absolute owner hereof and is 
     empowered to transfer absolute title hereto by endorsement and delivery 
     hereof to a bona fide purchaser hereof for value; each prior taker or 
     owner waives and renounces all of his rights in this Warrant in favor of 
     each such bona fide purchaser, and each bona fide purchaser shall 
     acquire absolute title hereto and to all rights represented hereby.

          (3)  EXCHANGE OF WARRANT UPON A TRANSFER.  On surrender of this
     Warrant for exchange, properly endorsed on the Assignment Form and subject
     to the provisions of this Warrant with respect to compliance with the Act
     and with the limitations on assignments and transfers contained in this
     SECTION 8, the Company at its expense shall issue to or on the order of the
     Holder a new warrant or warrants of like tenor, in the name of the Holder
     or as the Holder (on payment by the Holder of any applicable transfer
     taxes) may direct, for the number of shares issuable upon exercise hereof.

     (4)  COMPLIANCE WITH SECURITIES LAWS.

          (1)  The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant and the shares of Common Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account for
     investment, and that the Holder will not offer, sell or otherwise dispose
     of this Warrant or any shares of Common Stock to be issued upon exercise
     hereof except under circumstances that will not result in a violation of
     the Act or any state securities laws.  Upon exercise of this Warrant, the
     Holder shall, if requested by the Company, confirm in writing, in a form
     satisfactory to the Company, that the shares of Common Stock so purchased
     are being acquired for investment, and not with a view toward distribution
     or resale in violation of applicable securities laws.

          (2)  All shares of Common Stock issued upon exercise hereof shall be
     stamped or imprinted with a legend in substantially the following form (in
     addition to any legend required by state securities laws and the Asset and
     Securities Purchase Agreement of even date herewith):

               THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
               INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
               APPLICABLE STATE SECURITIES LAWS.  SUCH SECURITIES MAY NOT
               BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
               OR IN A TRANSACTION WHICH, IN THE OPINION OF COUNSEL TO THE
               HOLDERS OF THIS WARRANT (WHICH COUNSEL SHALL BE SATISFACTORY
               TO THE COMPANY), QUALIFIES AS AN EXEMPT TRANSACTION UNDER
               THE SECURITIES ACT AND THE RULES PROMULGATED BY THE
               SECURITIES AND EXCHANGE COMMISSION THEREUNDER.

     9.   RESERVATION OF STOCK.  The Company covenants that during the term 
this Warrant is exercisable, the Company will reserve from its authorized and 
unissued Common Stock a sufficient number of shares to provide for the 
issuance of Common Stock upon the exercise of this Warrant and, from time to 
time, will take all steps necessary to amend its  corporate charter to 
provide sufficient reserves of shares of Common Stock issuable upon exercise 
of the Warrant.  The Company further covenants that all shares that may be 
issued upon the exercise of this Warrant will be free from all taxes, liens 
and charges except for restrictions on transfer and any taxes, liens and 
charges imposed on the Holder unrelated to the Company's issuance of shares 
upon exercise of the Warrant.

     10.  NOTICES.  All such notices, advices and communications hereunder 
shall be deemed to have been received (i) in the case of personal delivery, 
on the date of such delivery and (ii) in the case of mailing, on the third 
business day following the date of such mailing.

     11.  AMENDMENTS.  Any term of this Warrant may be amended with the 
written consent of the Company and all of the Holders of this Warrant.

     12.  ADJUSTMENTS.  The Exercise Price and the number of shares 
purchasable hereunder are subject to adjustment from time to time as follows:

          (1)  ADJUSTMENT FOR DIVIDENDS IN OTHER STOCK, PROPERTY, ETC.;
     RECLASSIFICATION, ETC.  In case at any time and from time to time while
     this Warrant (or any Warrant issued in exchange or replacement hereof) is
     outstanding and unexpired, the holders of Common Stock shall have received,
     or (on or after the record date fixed for the determination of stockholders
     eligible to receive) shall have become entitled to receive, without payment
     therefor,

               (1)  other or additional stock or other securities or property
          (other than cash) by way of dividend; or

               (2)  other or additional stock or other securities or property by
          way of stock-split, spin-off, split-up, reclassification,
          recapitalization, combination of shares or similar corporate
          rearrangement,

     other than additional shares of Common Stock or Convertible Securities (as
     defined in SECTION 12(d)) or any rights or options to acquire any of the
     foregoing, adjustments in respect of which are provided for hereafter, then
     and in each such case the Holder, upon the exercise hereof, shall be
     entitled to receive the amount of stock and other securities and property
     which such Holder would hold on the date of such exercise if on the
     original issue date he had been the holder of record of the number of
     shares of Common Stock called for on the face of this Warrant and had
     thereafter, during the period from the original issue date to and including
     the date of such exercise, retained such shares and all such other or
     additional stock and other securities and properties receivable by him as
     aforesaid during such period, giving effect to all adjustments called for
     during such period by this SECTION 12.

          (2)  ADJUSTMENTS FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
     case of any reorganization of the Company (or any other issuer of other
     securities) at any time and from time to time while this Warrant (or any
     Warrant issued in exchange or replacement hereof) is outstanding and
     unexpired, or if the Company (or such other issuer) shall transfer all or
     substantially all of its properties or assets to or consolidate with or
     merge into any other person (corporate or otherwise), then and in each such
     case the Holder, upon the exercise hereof, at any time after the
     consummation of such reorganization, conveyance, consolidation or merger,
     shall be entitled to receive, in lieu of the Common Stock (or other
     securities) issuable upon such exercise prior to such consummation, the
     stock and other securities or property (including cash) to which such
     Holder would have been entitled upon such consummation if such Holder had
     so exercised this Warrant immediately prior thereto, all subject to further
     adjustments thereafter as provided in SECTION 12(a) and SECTION 12(c); in
     each such case, the terms of this Warrant shall be applicable to the shares
     of stock and other securities receivable upon the exercise of this Warrant
     after such consummation and shall be binding upon the issuer thereof.

          (3)  ADJUSTMENT FOR ISSUE OR SALE OF COMMON STOCK AT LESS THAN FAIR
     MARKET VALUE.  In case at any time or from time to time while this Warrant
     (or any Warrant issued in exchange or replacement hereof) is outstanding
     and unexpired the Company shall issue or sell shares of its 


                                     -4-

<PAGE>

     Common Stock (other than shares of Common Stock excepted from the 
     provisions of this SECTION 12(c) by SECTION 12(h) without consideration 
     or for a consideration per share less than the Fair Market Value (as 
     defined in SECTION 12(d)) in effect immediately prior to such issue or 
     sale, then and in each such case the Pro Forma Exercise Price (as 
     defined in SECTION 12(d)) shall be adjusted to reflect such issue or 
     sale; and the holder of this Warrant, upon the exercise hereof, shall be 
     entitled to receive the number of shares of Common Stock determined by 
     multiplying the number of shares of Common Stock which would otherwise 
     (but for the provisions of this SECTION 12(c) be issuable upon such 
     exercise by the fraction of which (i) the numerator is the Exercise 
     Price and (ii) the denominator is the Pro Forma Exercise Price, both as 
     in effect on the date of such exercise.

          (4)  DEFINITIONS, ETC.  For purposes of this SECTION 12:

          (1)  The "PRO FORMA EXERCISE PRICE" per share of Common Stock, which
     shall be adjusted and readjusted from time to time as provided in this
     SECTION 12 (and, as so adjusted or readjusted, shall remain in effect until
     a further adjustment or readjustment thereof is required by this SECTION
     12), shall (upon any such adjustment or readjustment) be computed (to the
     nearest cent, a half cent being considered a full cent) by dividing

               (x)  the sum of (i) the result obtained by multiplying the
          number of shares of Common Stock of the Company outstanding
          immediately prior to such issue or sale by the Pro Forma Exercise
          Price in effect immediately prior to such issue or sale and
          (ii) the consideration, if any, received by the Company upon such
          issue or sale by

               (y)  the number of shares of Common Stock of the Company
          outstanding immediately after such issue or sale, 
     PROVIDED THAT (i) prior to the first issue or sale referred to in 
     SECTION 12(c) the Pro Forma Exercise Price shall be the Exercise Price 
     in effect on the date of this Warrant and (ii) at no time shall the Pro 
     Forma Exercise Price exceed the Exercise Price then in effect.

          (2)  The term "CONVERTIBLE SECURITIES" shall mean any stock (other
     than Common Stock) or other securities directly or indirectly convertible
     into or exchangeable for Common Stock.

          (3)  The consideration received by the Company for any issue or sale
     of Common Stock shall include any consideration received for shares of
     Common Stock referred to in SECTION 12(h), and shall,

               (1)  insofar as it consists of cash, be computed at the net 
          amount thereof received by the Company after deduction of any 
          expenses payable at the Company and any underwriting or similar 
          commissions, compensation or concessions paid or allowed by the 
          Company in connection with such issue or sale;

               (2)  insofar as it consists of assets other than cash, be 
          computed at the fair value thereof as determined in good faith by 
          the Board of Directors of the Company, but in no event at more than 
          the amount at which such tangible or intangible assets are recorded 
          on the books of the Company for accounting purposes; and

               (3)  insofar as it is attributable to the issue or sale of 
          stock or other securities or other assets of the Company other than 
          Common Stock or Convertible 


                                     -5-

<PAGE>

          Securities, be allocated in good faith by the Board of Directors of 
          the Company among such other stock, securities and assets and Common 
          Stock and Convertible Securities.

               (4)  The date of the issue or sale of Common Stock issuable 
          upon the exercise of any rights or options or the conversion or 
          exchange of any Convertible Securities shall be deemed to be the 
          date of issue or sale of such rights or options or such Convertible 
          Securities, or rights or options to subscribe for, purchase or 
          otherwise acquire such Convertible Securities; PROVIDED that if a 
          record of the holders of any class of securities shall be taken for 
          the purpose of entitling such holders to receive any dividend or 
          other distribution payable in, or any rights or options to 
          subscribe for, purchase or otherwise acquire, Common Stock or 
          Convertible Securities, the date of the issue or sale of any Common 
          Stock issuable in payment of any such dividend or other 
          distribution or upon the exercise of any such rights or options, or 
          upon the conversion or exchange of any Convertible Securities so 
          issuable, shall be deemed to be the date of such record.

               (5)  The term "FAIR MARKET VALUE" shall mean the value of the 
          Common Stock as determined by the Company's Board of Directors in 
          good faith; PROVIDED, HOWEVER, that where there exists a public 
          market for the Company's Common Stock, the Fair Market Value per 
          share shall be equal to the average of the closing bid and asked 
          prices of the Common Stock as quoted on the NASDAQ Small-Cap Market 
          or the closing price quoted on the Nasdaq National Market or on any 
          exchange on which the Common Stock is listed, whichever is 
          applicable, for the five (5) trading days prior to the date of 
          determination of Fair Market Value.

          (5)  ADJUSTMENTS FOR STOCK DIVIDENDS, ETC.  In case the Company 
     shall declare any dividend or make any other distribution on any stock 
     of the Company of any class, payable in Common Stock or Convertible 
     Securities, such declaration or other distribution shall be deemed to be 
     an issue or sale, without consideration, of such Common Stock or 
     Convertible Securities, as the case may be, and the Pro Forma Exercise 
     Price shall thereupon be adjusted to reflect such issue or sale.

          (6)  ADJUSTMENTS FOR ISSUES, ETC. OF OPTIONS OR CONVERTIBLE
     SECURITIES.  In case the Company shall (a) grant any rights or options to
     subscribe for, purchase or otherwise acquire Common Stock, or (b) issue or
     sell any Convertible Securities, the price per share of Common Stock
     issuable upon the exercise of such rights or options or the conversion or
     exchange of such Convertible Securities shall be determined by dividing
     (i) the total amount, if any, received or receivable by the Company as
     consideration for the granting of such rights or options or the issue or
     sale of such Convertible Securities, plus the minimum aggregate amount of
     additional consideration payable to the Company upon the exercise of such
     rights or options or the conversion or exchange of such Convertible
     Securities, by (ii) the maximum number of shares of Common Stock issuable
     upon such exercise or conversion or exchange, all as the case may be.  If
     the price per share so determined is less than the Fair Market Value
     immediately prior to the granting of such rights or options or the issue or
     sale of such Convertible Securities, such granting or issue or sale shall
     be deemed to be an issue or sale for cash of such maximum number of shares
     of Common Stock at such price per share, and the Pro Forma Exercise Price
     shall thereupon be adjusted to reflect (on the basis of such determination)
     such issue or sale, provided that

               (1)  if such rights or options or Convertible Securities by 
          their terms provide, with the passage of time or otherwise, for any 
          increase in the amount of additional consideration payable to the 
          Company or decrease in the number of shares of Common 

                                     -6-

<PAGE>

          Stock issuable upon such exercise or conversion or exchange (by 
          change of rate or otherwise), the Pro Forma Exercise Price shall, 
          upon each such increase or decrease becoming effective, be 
          readjusted to reflect such increase or decrease insofar as it 
          affects rights of acquisition, exchange or conversion which have 
          not theretofore expired, and

               (2)  upon the expiration of such rights or options or the 
          rights of conversion or exchange of such Convertible Securities, if 
          any thereof shall not have been exercised, the Pro Forma Exercise 
          Price shall, upon such expiration, be readjusted and shall 
          thereafter be such as it would have been had it been adjusted on 
          the basis that (x) the only shares of Common Stock so issued were 
          the shares of Common Stock issued or sold upon the exercise of such 
          rights or options or the rights of conversion or exchange of such 
          Convertible Securities and (y) such shares of Common Stock were 
          issued or sold for the consideration actually received by the 
          Company upon such exercise plus the consideration, if any, actually 
          received by the Company for the granting of all of such rights or 
          options, whether or not exercised, or for the issue or sale of all 
          such Convertible Securities which shall have been converted or 
          exchanged,

     all as the case may be; and provided further that no such readjustment
     shall have the effect of increasing the Pro Forma Exercise Price by an
     amount in excess of the amount of the adjustment thereof initially made in
     respect of the granting of such rights or options or the issue or sale of
     such Convertible Securities.  In case the Company shall grant any rights or
     options to subscribe for, purchase or otherwise acquire Convertible
     Securities, such Convertible Securities shall be deemed, for the purposes
     of this SECTION 12(f), to have been issued or sold; and the total amount
     received or receivable by the Company as consideration for such issue or
     sale shall be computed (for the purposes of clause (i) of this SECTION
     12(f), in determining the price per share of Common Stock issuable upon the
     conversion or exchange of such Convertible Securities) and the Pro Forma
     Exercise Price shall be adjusted and readjusted as provided above in this
     SECTION 12(f) in the case of rights or options for the acquisition of
     shares of Common Stock. 

          (7)  DILUTION IN CASE OF OTHER SECURITIES.  In case any other
     securities shall be issued or sold, or shall become subject to issue upon
     the conversion or exchange or any stock (or other securities) of the
     Company (or any other issuer of other securities or any other person
     referred to in SECTION 12(b) or to subscription, purchase or other
     acquisition pursuant to any rights or options granted by the Company (or
     such other issuer or person), for a consideration per share such as to
     dilute the purchase rights evidenced by this Warrant, the computations,
     adjustments and readjustments provided for in this SECTION 12 with respect
     to the Pro Forma Exercise Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of other securities
     from time to time receivable upon the exercise of the Warrant, so as to
     protect the Holder of the Warrant against the effect of such dilution.

          (8)  EXCEPTED ISSUES.  The following issues of Common Stock shall, for
     the purposes of SECTION 12(c), be deemed not to be issues or sales of
     Common Stock at less than the Fair Market Value, and no adjustment or
     readjustment pursuant to this SECTION 12 in the Pro Forma Exercise Price
     shall be made in respect thereof:

               (1)  the issuance of Common Stock (or other securities) upon 
          the exercise of this Warrant or the $10.50 Warrant issued to SAIC 
          on the date hereof; 

               (2)  the issuance of Common Stock (or other securities) upon 
          the exercise of warrants, options, or convertible securities 
          outstanding on the date hereof; and


                                     -7-

<PAGE>

               (3)  the issuance of Common Stock (and options therefor) 
          pursuant to employee stock option plans approved by the Company's 
          Board of Directors.

          (9)  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment to
     its certificate of incorporation or through any reorganization, sale of
     assets, consolidation, merger, dissolution, issue or sale of securities, or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms of this Warrant, but will at all times in
     good faith assist in the carrying out of all such terms and in the taking
     of all such action as may be necessary or appropriate in order to protect
     the rights of the Holder of the Warrant against dilution or other
     impairment.  Without limiting the generality of the foregoing, the Company
     (a) will not increase the par value of any shares of stock receivable upon
     the exercise of the Warrant above the amount payable therefor upon such
     exercise; (b) will take all such action as may be necessary or appropriate
     in order that the Company may validly and legally issue fully paid and
     nonassessable shares of stock upon the full exercise of the Warrant as from
     time to time outstanding; and (c) will not transfer all or substantially
     all of its properties and assets to any other person (corporate or
     otherwise), or consolidate with or merge into any other person or permit
     any such person to consolidate with or merge into the Company (if the
     Company is not the surviving person), unless such other person shall
     expressly assume in writing and will be bound by all the terms of this
     Warrant. 

          (10) CERTIFICATE AS TO ADJUSTMENTS.  In each case of any adjustment or
     readjustment in the shares of Common Stock (or other securities) issuable
     upon the exercise of the Warrant, the Company's Chief Financial Officer
     will promptly compute such adjustment or readjustment in accordance with
     the terms of the Warrant and prepare a certificate setting forth such
     adjustment or readjustment and showing in detail the facts upon which such
     adjustment or readjustment is based, including a statement of (a) the
     consideration received or to be received by the Company for any additional
     shares of Common Stock issued or sold or deemed to have been issued or
     sold, (b) the number of shares of Common Stock outstanding or deemed to be
     outstanding and (c) the Pro Forma Exercise Price in effect immediately
     prior to such issue or sale and as adjusted and readjusted (if required by
     SECTION 12) on account thereof.  The Company will forthwith mail a copy of
     each such certificate to each Holder.  Upon request, the Company will mail
     to the Holder a certificate of the Company's Chief Financial Officer
     containing a statement of the Pro Forma Exercise Price at the time in
     effect and showing how it was calculated.

          (11) NOTICES OF RECORD DATE, ETC.  In the event of:

               (1)  any taking by the Company of a record of the holders of 
          any class of securities for the purpose of determining the holders 
          thereof who are entitled to receive any dividend (other than a cash 
          dividend) or other distribution, or any right to subscribe for, 
          purchase or otherwise acquire any shares of stock of any class or 
          any other securities or property, or to receive any other right; or

               (2)  any capital reorganization of the Company, any 
          reclassification or recapitalization of the capital stock of the 
          Company or any conveyance of all or substantially all the assets of 
          the Company to or consolidation or merger of the Company with or 
          into any other corporation; or

               (3)  any voluntary or involuntary dissolution, liquidation or 
          winding up of the Company; 

     then and in each such event the Company will mail or cause to be mailed to
     the Holder a notice specifying (i) the date on which any such record is to
     be taken for the purpose of such dividend, 


                                     -8-

<PAGE>

     distribution or right, and stating the amount and character of such 
     dividend, distribution or right; (ii) the date on which any such 
     reorganization, reclassification, conveyance, consolidation, merger, 
     dissolution, liquidation, or winding up is to take place, and the time, 
     if any is to be fixed, as of which the holders of record of Common 
     Stock (or other securities) shall be entitled to exchange their shares 
     of Common Stock (or other securities) for securities or other property 
     deliverable upon such reorganization, reclassification, recapitalization,
     conveyance, consolidation, merger, dissolution, liquidation, or winding 
     up; and (iii) the amount and character of any stock or other securities, 
     or rights or options with respect thereto, proposed to be issued or 
     granted, the date of such proposed issue or grant and the persons or 
     class of persons to whom such proposed issue or grant is to be offered or 
     made.  Such notice shall be mailed at least 15 days prior to the date 
     therein specified.

     2.   MISCELLANEOUS.  

          (1)  SUCCESSORS AND ASSIGNS.  This Warrant and the rights evidenced
     hereby shall inure to the benefit of and be binding upon the successors of
     the Company and the Holder and their respective permitted assigns.  The
     provisions of this Warrant are intended to be for the benefit of all
     Holders from time to time of this Warrant, and shall be enforceable by any
     such Holder.

          (2)  HEADINGS.  The headings of the Sections of this Warrant are for
     the convenience of reference only and shall not, for any purpose, be deemed
     a part of this Warrant.

          (3)  CHOICE OF LAW.  This Warrant and the performance or breach
     thereof shall be governed by and interpreted as to substantive matters in
     accordance with the applicable laws of the State of Delaware (excluding its

of the Company, $0.01 par value (the "COMMON STOCK"), in the amount set forth 
in SECTION 2, upon surrender hereof, at the principal office of the Company 
referred to below, with a duly executed Notice of Exercise in the form 
attached, and simultaneous payment therefor in lawful money of the United 
States, at the Exercise Price set forth in SECTION 3.  The number, character 
and Exercise Price of such shares of Common Stock are subject to adjustment 
as provided below.  The term "Warrant" as used herein shall include this 
Warrant, and any warrants delivered in substitution or exchange therefor as 
provided herein.

     1.   TERM OF WARRANT.  Subject to the terms and conditions set forth 
herein, this Warrant shall be exercisable, in whole or in part, at any time 
or from time to time before 5:00 p.m., on September 25, 2000.  After such

FIFTY THOUSAND (750,000).

     4.   EXERCISE OF WARRANT.


                                     -1-

<PAGE>

          (1)  METHOD OF EXERCISE.  The purchase rights represented by this
     Warrant are exercisable by the Holder in whole or in part, at any time, or
     from time to time, during the term hereof as described in SECTION 1 above,
     by the surrender of this Warrant and delivery of the Notice of Exercise
     annexed hereto duly completed and executed on behalf of the Holder, at the
     office of the Company, and upon payment equal to the product of the
     Exercise Price multiplied by the number of shares designated by the Holder
     in the Notice of Exercise in cash or by check payable to the Company.

          (2)  OTHER MATTERS.  This Warrant shall be deemed to have been
     exercised immediately prior to the close of business on the date of its
     surrender for exercise as provided above, and the person entitled to
     receive the shares of Common Stock issuable upon such exercise shall be
     treated for all purposes as the holder of record of such shares as of the
     close of business on such date.  As promptly as practicable on or after
     such date and in any event within ten (10) days thereafter, the Company at
     its expense shall issue and deliver to the person or persons entitled to
     receive the same a certificate or certificates for the number of shares
     issued upon such exercise.  In the event that this Warrant is exercised in
     part, the Company at its expense will execute and deliver a new Warrant of
     like tenor exercisable for the remaining number of shares for which this
     Warrant may then be exercised.

     5.   NO FRACTIONAL SHARES OR SCRIP.  No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant.  In lieu of any fractional share to which the Holder would otherwise be
entitled, the Company shall make a cash payment equal to the Exercise Price
multiplied by such fraction.

     6.   REPLACEMENT OF WARRANT.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and substance to the Company
or, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor and amount.

     7.   NO RIGHTS AS STOCKHOLDER.  This Warrant shall not entitle its Holder
to any of the rights of a stockholder of the Company.

     8.   TRANSFER OF WARRANT.

          (1)  WARRANT REGISTER.  The Company will maintain a register (the
     "WARRANT REGISTER") containing the names and addresses of the Holder or
     Holders.  Any Holder of this Warrant or any portion thereof may change his
     or her address as shown on the Warrant Register by written notice to the
     Company requesting such change.  Any notice or written communication
     required or permitted to be given to the Holder may be delivered or given
     by mail to such Holder as shown on the Warrant Register and at the address
     shown on the Warrant Register.  Until this Warrant is transferred on the
     Warrant Register of the Company, the Company may treat the Holder as shown
     on the Warrant Register as the absolute owner of this Warrant for all
     purposes, notwithstanding any notice to the contrary.

          (2)  TRANSFERABILITY AND NONNEGOTIABILITY OF WARRANT.  This Warrant
     may not be transferred or assigned in whole or in part without compliance
     with all applicable federal and state securities laws by the transferor and
     the transferee (including the delivery of investment representation letters
     and legal opinions reasonably satisfactory to the Company).  Subject to
     compliance with the foregoing and the Securities Act of 1933, as amended
     (the "ACT"), and applicable state securities laws, title to this Warrant
     may be transferred by endorsement (by the 


                                     -2-

<PAGE>

     Holder executing the Assignment Form annexed hereto) and delivery in the 
     same manner as a negotiable instrument transferable by endorsement and 
     delivery.  The Holder or owner hereof by the taking hereof consents and 
     agrees that any person in possession of this Warrant properly endorsed 
     for transfer to such person (including endorsed in blank) is authorized 
     to represent himself as absolute owner hereof and is empowered to 
     transfer absolute title hereto by endorsement and delivery hereof to a 
     bona fide purchaser hereof for value; each prior taker or owner waives 
     and renounces all of his rights in this Warrant in favor of each such 
     bona fide purchaser, and each bona fide purchaser shall acquire absolute 
     title hereto and to all rights represented hereby.

          (3)  EXCHANGE OF WARRANT UPON A TRANSFER.  On surrender of this
     Warrant for exchange, properly endorsed on the Assignment Form and subject
     to the provisions of this Warrant with respect to compliance with the Act
     and with the limitations on assignments and transfers contained in this
     SECTION 8, the Company at its expense shall issue to or on the order of the
     Holder a new warrant or warrants of like tenor, in the name of the Holder
     or as the Holder (on payment by the Holder of any applicable transfer
     taxes) may direct, for the number of shares issuable upon exercise hereof.

          (4)  COMPLIANCE WITH SECURITIES LAWS.

               (1)  The Holder of this Warrant, by acceptance hereof, 
          acknowledges that this Warrant and the shares of Common Stock to be 
          issued upon exercise hereof are being acquired solely for the 
          Holder's own account for investment, and that the Holder will not 
          offer, sell or otherwise dispose of this Warrant or any shares of 
          Common Stock to be issued upon exercise hereof except under 
          circumstances that will not result in a violation of the Act or any 
          state securities laws.  Upon exercise of this Warrant, the Holder 
          shall, if requested by the Company, confirm in writing, in a form 
          satisfactory to the Company, that the shares of Common Stock so 
          purchased are being acquired for investment, and not with a view 
          toward distribution or resale in violation of applicable securities 
          laws.

               (2)  All shares of Common Stock issued upon exercise hereof 
          shall be stamped or imprinted with a legend in substantially the 
          following form (in addition to any legend required by state 
          securities laws and the Asset and Securities Purchase Agreement of 
          even date herewith):

               THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
               INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
               ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
               APPLICABLE STATE SECURITIES LAWS.  SUCH SECURITIES MAY NOT
               BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION
               OR IN A TRANSACTION WHICH, IN THE OPINION OF COUNSEL TO THE
               HOLDERS OF THIS WARRANT (WHICH COUNSEL SHALL BE SATISFACTORY
               TO THE COMPANY), QUALIFIES AS AN EXEMPT TRANSACTION UNDER
               THE SECURITIES ACT AND THE RULES PROMULGATED BY THE
               SECURITIES AND EXCHANGE COMMISSION THEREUNDER.

     9.   RESERVATION OF STOCK.  The Company covenants that during the term 
this Warrant is exercisable, the Company will reserve from its authorized and 
unissued Common Stock a sufficient number of shares to provide for the 
issuance of Common Stock upon the exercise of this Warrant and, from time to 
time, will take all steps necessary to amend its  corporate charter to 
provide sufficient reserves of shares of Common Stock issuable upon exercise 
of the Warrant.  The Company further covenants that all shares that may be 
issued upon the exercise of this Warrant will be free from all taxes, liens 
and charges except for restrictions on transfer and any taxes, liens and 
charges imposed on the Holder unrelated to the Company's issuance of shares 
upon exercise of the Warrant.

     10.  NOTICES.  All such notices, advices and communications hereunder 
shall be deemed to have been received (i) in the case of personal delivery, 
on the date of such delivery and (ii) in the case of mailing, on the third 
business day following the date of such mailing.

     11.  AMENDMENTS.  Any term of this Warrant may be amended with the

     12.  ADJUSTMENTS.  The Exercise Price and the number of shares 
purchasable hereunder are subject to adjustment from time to time as follows:

          (1)  ADJUSTMENT FOR DIVIDENDS IN OTHER STOCK, PROPERTY, ETC.;
     RECLASSIFICATION, ETC.  In case at any time and from time to time while
     this Warrant (or any Warrant issued in exchange or replacement hereof) is
     outstanding and unexpired, the holders of Common Stock shall have received,
     or (on or after the record date fixed for the determination of stockholders
     eligible to receive) shall have become entitled to receive, without payment
     therefor,

               (1)  other or additional stock or other securities or property 
          (other than cash) by way of dividend; or

               (2)  other or additional stock or other securities or 
          property by way of stock-split, spin-off, split-up, reclassification,
          recapitalization, combination of shares or similar corporate       
          rearrangement,

     other than additional shares of Common Stock or Convertible Securities (as
     defined in SECTION 12(d)) or any rights or options to acquire any of the
     foregoing, adjustments in respect of which are provided for hereafter, then
     and in each such case the Holder, upon the exercise hereof, shall be
     entitled to receive the amount of stock and other securities and property
     which such Holder would hold on the date of such exercise if on the
     original issue date he had been the holder of record of the number of
     shares of Common Stock called for on the face of this Warrant and had
     thereafter, during the period from the original issue date to and including
     the date of such exercise, retained such shares and all such other or
     additional stock and other securities and properties receivable by him as
     aforesaid during such period, giving effect to all adjustments called for
     during such period by this SECTION 12.

          (2)  ADJUSTMENTS FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.  In
     case of any reorganization of the Company (or any other issuer of other
     securities) at any time and from time to time while this Warrant (or any
     Warrant issued in exchange or replacement hereof) is outstanding and
     unexpired, or if the Company (or such other issuer) shall transfer all or
     substantially all of its properties or assets to or consolidate with or
     merge into any other person (corporate or otherwise), then and in each such
     case the Holder, upon the exercise hereof, at any time after the
     consummation of such reorganization, conveyance, consolidation or merger,
     shall be entitled to receive, in lieu of the Common Stock (or other
     securities) issuable upon such exercise prior to such consummation, the
     stock and other securities or property (including cash) to which such
     Holder would have been entitled upon such consummation if such Holder had
     so exercised this Warrant immediately prior thereto, all subject to further
     adjustments thereafter as provided in SECTION 12(a) and SECTION 12(c); in
     each such case, the terms of this Warrant shall be applicable to the shares
     of stock and other securities receivable upon the exercise of this Warrant
     after such consummation and shall be binding upon the issuer thereof.

          (3)  ADJUSTMENT FOR ISSUE OR SALE OF COMMON STOCK AT LESS THAN FAIR
     MARKET VALUE.  In case at any time or from time to time while this Warrant
     (or any Warrant issued in exchange or replacement hereof) is outstanding
     and unexpired the Company shall issue or sell shares of its 


                                     -4-

<PAGE>

     Common Stock (other than shares of Common Stock excepted from the 
     provisions of this SECTION 12(c) by SECTION 12(h) without consideration 
     or for a consideration per share less than the Fair Market Value (as 
     defined in SECTION 12(d)) in effect immediately prior to such issue or 
     sale, then and in each such case the Pro Forma Exercise Price (as 
     defined in SECTION 12(d)) shall be adjusted to reflect such issue or 
     sale; and the holder of this Warrant, upon the exercise hereof, shall be 
     entitled to receive the number of shares of Common Stock determined by 
     multiplying the number of shares of Common Stock which would otherwise 
     (but for the provisions of this SECTION 12(c) be issuable upon such 
     exercise by the fraction of which (i) the numerator is the Exercise 
     Price and (ii) the denominator is the Pro Forma Exercise Price, both as 
     in effect on the date of such exercise.

          (4)  DEFINITIONS, ETC.  For purposes of this SECTION 12:

               (1)  The "PRO FORMA EXERCISE PRICE" per share of Common Stock, 
          which shall be adjusted and readjusted from time to time as 
          provided in this SECTION 12 (and, as so adjusted or readjusted, 
          shall remain in effect until a further adjustment or readjustment 
          thereof is required by this SECTION 12), shall (upon any such 
          adjustment or readjustment) be computed (to the nearest cent, a 
          half cent being considered a full cent) by dividing

                    (x)  the sum of (i) the result obtained by multiplying the
               number of shares of Common Stock of the Company outstanding
               immediately prior to such issue or sale by the Pro Forma Exercise
               Price in effect immediately prior to such issue or sale and
               (ii) the consideration, if any, received by the Company upon such
               issue or sale by

                    (y)  the number of shares of Common Stock of the Company
               outstanding immediately after such issue or sale, 
          PROVIDED THAT (i) prior to the first issue or sale referred to in
          SECTION 12(c) the Pro Forma Exercise Price shall be the Exercise Price
          in effect on the date of this Warrant and (ii) at no time shall the
          Pro Forma Exercise Price exceed the Exercise Price then in effect.

               (2)  The term "CONVERTIBLE SECURITIES" shall mean any stock 
          (other than Common Stock) or other securities directly or 
          indirectly convertible into or exchangeable for Common Stock.

               (3)  The consideration received by the Company for any issue 
          or sale of Common Stock shall include any consideration received 
          for shares of Common Stock referred to in SECTION 12(h), and shall,

                    (1)  insofar as it consists of cash, be computed at the net
               amount thereof received by the Company after deduction of any 
               expenses payable at the Company and any underwriting or 
               similar commissions, compensation or concessions paid or 
               allowed by the Company in connection with such issue or sale;

                    (2)  insofar as it consists of assets other than cash, be 
               computed at the fair value thereof as determined in good faith 
               by the Board of Directors of the Company, but in no event at 
               more than the amount at which such tangible or intangible 
               assets are recorded on the books of the Company for accounting 
               purposes; and

                    (3)  insofar as it is attributable to the issue or sale 
               of stock or other securities or other assets of the Company 
               other than Common Stock or Convertible 


                                     -5-

<PAGE>

               Securities, be Company among such other stock, securities and 
               assets and Common Stock and Convertible Securities.

              (4)  The date of the issue or sale of Common Stock issuable 
          upon the exercise of any rights or options or the conversion or 
          exchange of any Convertible Securities shall be deemed to be the 
          date of issue or sale of such rights or options or such Convertible 
          Securities, or rights or options to subscribe for, purchase or 
          otherwise acquire such Convertible Securities; PROVIDED that if a 
          record of the holders of any class of securities shall be taken for 
          the purpose of entitling such holders to receive any dividend or 
          other distribution payable in, or any rights or options to 
          subscribe for, purchase or otherwise acquire, Common Stock or 
          Convertible Securities, the date of the issue or sale of any Common 
          Stock issuable in payment of any such dividend or other 
          distribution or upon the exercise of any such rights or options, or 
          upon the conversion or exchange of any Convertible Securities so 
          issuable, shall be deemed to be the date of such record.

               (5)  The term "FAIR MARKET VALUE" shall mean the value of the 
          Common Stock as determined by the Company's Board of Directors in 
          good faith; PROVIDED, HOWEVER, that where there exists a public 
          market for the Company's Common Stock, the Fair Market Value per 
          share shall be equal to the average of the closing bid and asked 
          prices of the Common Stock as quoted on the NASDAQ Small-Cap Market 
          or the closing price quoted on the Nasdaq National Market or on any 
          exchange on which the Common Stock is listed, whichever is 
          applicable, for the five (5) trading days prior to the date of 
          determination of Fair Market Value.

          (5)  ADJUSTMENTS FOR STOCK DIVIDENDS, ETC.  In case the Company shall
     declare any dividend or make any other distribution on any stock of the
     Company of any class, payable in Common Stock or Convertible Securities,
     such declaration or other distribution shall be deemed to be an issue or
     sale, without consideration, of such Common Stock or Convertible
     Securities, as the case may be, and the Pro Forma Exercise Price shall
     thereupon be adjusted to reflect such issue or sale.

          (6)  ADJUSTMENTS FOR ISSUES, ETC. OF OPTIONS OR CONVERTIBLE
     SECURITIES.  In case the Company shall (a) grant any rights or options to
     subscribe for, purchase or otherwise acquire Common Stock, or (b) issue or
     sell any Convertible Securities, the price per share of Common Stock
     issuable upon the exercise of such rights or options or the conversion or
     exchange of such Convertible Securities shall be determined by dividing
     (i) the total amount, if any, received or receivable by the Company as
     consideration for the granting of such rights or options or the issue or
     sale of such Convertible Securities, plus the minimum aggregate amount of
     additional consideration payable to the Company upon the exercise of such
     rights or options or the conversion or exchange of such Convertible
     Securities, by (ii) the maximum number of shares of Common Stock issuable
     upon such exercise or conversion or exchange, all as the case may be.  If
     the price per share so determined is less than the Fair Market Value
     immediately prior to the granting of such rights or options or the issue or
     sale of such Convertible Securities, such granting or issue or sale shall
     be deemed to be an issue or sale for cash of such maximum number of shares
     of Common Stock at such price per share, and the Pro Forma Exercise Price
     shall thereupon be adjusted to reflect (on the basis of such determination)
     such issue or sale, provided that

               (1)  if such rights or options or Convertible Securities by 
          their terms provide, with the passage of time or otherwise, for any 
          increase in the amount of additional consideration payable to the 
          Company or decrease in the number of shares of Common 


                                     -6-

<PAGE>

          Stock issuable upon such exercise or conversion or exchange (by 
          change of rate or otherwise), the Pro Forma Exercise Price shall, 
          upon each such increase or decrease becoming effective, be 
          readjusted to reflect such increase or decrease insofar as it 
          affects rights of acquisition, exchange or conversion which have 
          not theretofore expired, and

               (2)  upon the expiration of such rights or options or the 
          rights of conversion or exchange of such Convertible Securities, if 
          any thereof shall not have been exercised, the Pro Forma Exercise 
          Price shall, upon such expiration, be readjusted and shall 
          thereafter be such as it would have been had it been adjusted on 
          the basis that (x) the only shares of Common Stock so issued were 
          the shares of Common Stock issued or sold upon the exercise of such 
          rights or options or the rights of conversion or exchange of such 
          Convertible Securities and (y) such shares of Common Stock were 
          issued or sold for the consideration actually received by the 
          Company upon such exercise plus the consideration, if any, actually 
          received by the Company for the granting of all of such rights or 
          options, whether or not exercised, or for the issue or sale of all 
          such Convertible Securities which shall have been converted or 
          exchanged,

     all as the case may be; and provided further that no such readjustment
     shall have the effect of increasing the Pro Forma Exercise Price by an
     amount in excess of the amount of the adjustment thereof initially made in
     respect of the granting of such rights or options or the issue or sale of
     such Convertible Securities.  In case the Company shall grant any rights or
     options to subscribe for, purchase or otherwise acquire Convertible
     Securities, such Convertible Securities shall be deemed, for the purposes
     of this SECTION 12(f), to have been issued or sold; and the total amount
     received or receivable by the Company as consideration for such issue or
     sale shall be computed (for the purposes of clause (i) of this SECTION
     12(f), in determining the price per share of Common Stock issuable upon the
     conversion or exchange of such Convertible Securities) and the Pro Forma
     Exercise Price shall be adjusted and readjusted as provided above in this
     SECTION 12(f) in the case of rights or options for the acquisition of
     shares of Common Stock. 

          (7)  DILUTION IN CASE OF OTHER SECURITIES.  In case any other
     securities shall be issued or sold, or shall become subject to issue upon
     the conversion or exchange or any stock (or other securities) of the
     Company (or any other issuer of other securities or any other person
     referred to in SECTION 12(b) or to subscription, purchase or other
     acquisition pursuant to any rights or options granted by the Company (or
     such other issuer or person), for a consideration per share such as to
     dilute the purchase rights evidenced by this Warrant, the computations,
     adjustments and readjustments provided for in this SECTION 12 with respect
     to the Pro Forma Exercise Price shall be made as nearly as possible in the
     manner so provided and applied to determine the amount of other securities
     from time to time receivable upon the exercise of the Warrant, so as to
     protect the Holder of the Warrant against the effect of such dilution.

          (8)  EXCEPTED ISSUES.  The following issues of Common Stock shall, for
     the purposes of SECTION 12(c), be deemed not to be issues or sales of
     Common Stock at less than the Fair Market Value, and no adjustment or
     readjustment pursuant to this SECTION 12 in the Pro Forma Exercise Price
     shall be made in respect thereof:

               (1)  the issuance of Common Stock (or other securities) upon 
          the exercise of this Warrant or the $8.00 Warrant issued to SAIC on 
          the date hereof; 

               (2)  the issuance of Common Stock (or other securities) upon 
          the exercise of warrants, options, or convertible securities 
          outstanding on the date hereof; and


                                     -7-

<PAGE>

               (3)  the issuance of Common Stock (and options therefor) 
          pursuant to employee stock option plans approved by the Company's 
          Board of Directors.

          (9)  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment to
     its certificate of incorporation or through any reorganization, sale of
     assets, consolidation, merger, dissolution, issue or sale of securities, or
     any other voluntary action, avoid or seek to avoid the observance or
     performance of any of the terms of this Warrant, but will at all times in
     good faith assist in the carrying out of all such terms and in the taking
     of all such action as may be necessary or appropriate in order to protect
     the rights of the Holder of the Warrant against dilution or other
     impairment.  Without limiting the generality of the foregoing, the Company
     (a) will not increase the par value of any shares of stock receivable upon
     the exercise of the Warrant above the amount payable therefor upon such
     exercise; (b) will take all such action as may be necessary or appropriate
     in order that the Company may validly and legally issue fully paid and
     nonassessable shares of stock upon the full exercise of the Warrant as from
     time to time outstanding; and (c) will not transfer all or substantially
     all of its properties and assets to any other person (corporate or
     otherwise), or consolidate with or merge into any other person or permit
     any such person to consolidate with or merge into the Company (if the
     Company is not the surviving person), unless such other person shall
     expressly assume in writing and will be bound by all the terms of this
     Warrant. 

          (10) CERTIFICATE AS TO ADJUSTMENTS.  In each case of any adjustment or
     readjustment in the shares of Common Stock (or other securities) issuable
     upon the exercise of the Warrant, the Company's Chief Financial Officer
     will promptly compute such adjustment or readjustment in accordance with
     the terms of the Warrant and prepare a certificate setting forth such
     adjustment or readjustment and showing in detail the facts upon which such
     adjustment or readjustment is based, including a statement of (a) the
     consideration received or to be received by the Company for any additional
     shares of Common Stock issued or sold or deemed to have been issued or
     sold, (b) the number of shares of Common Stock outstanding or deemed to be
     outstanding and (c) the Pro Forma Exercise Price in effect immediately
     prior to such issue or sale and as adjusted and readjusted (if required by
     SECTION 12) on account thereof.  The Company will forthwith mail a copy of
     each such certificate to each Holder.  Upon request, the Company will mail
     to the Holder a certificate of the Company's Chief Financial Officer
     containing a statement of the Pro Forma Exercise Price at the time in
     effect and showing how it was calculated.

          (11) NOTICES OF RECORD DATE, ETC.  In the event of:

               (1)  any taking by the Company of a record of the holders of any
          class of securities for the purpose of determining the holders thereof
          who are entitled to receive any dividend (other than a cash dividend)
          or other distribution, or any right to subscribe for, purchase or
          otherwise acquire any shares of stock of any class or any other 
          securities or property, or to receive any other right; or

               (2)  any capital reorganization of the Company, any
          reclassification or recapitalization of the capital stock of the
          Company or any conveyance of all or substantially all the assets of
          the Company to or consolidation or merger of the Company with or into
          any other corporation; or

               (3)  any voluntary or involuntary dissolution, liquidation or
          winding up of the Company; 

     then and in each such event the Company will mail or cause to be mailed to
     the Holder a notice specifying (i) the date on which any such record is to
     be taken for the purpose of such dividend, 


                                     -8-

<PAGE>

     distribution or right, and stating the amount and character of such 
     dividend, distribution or right; (ii) the date on which any such 
     reorganization, reclassification, conveyance, consolidation, merger, 
     dissolution, liquidation, or winding up is to take place, and the time, 
     if any is to be fixed, as of which the holders of record of Common Stock 
     (or other securities) shall be entitled to exchange their shares of 
     Common Stock (or other securities) for securities or other property 
     deliverable upon such reorganization, reclassification, 
     recapitalization, conveyance, consolidation, merger, dissolution, 
     liquidation, or winding up; and (iii) the amount and character of any 
     stock or other securities, or rights or options with respect thereto, 
     proposed to be issued or granted, the date of such proposed issue or

     grant is to be offered or made.  Such notice shall be mailed at least 15 
     days prior to the date therein specified.

     2.   MISCELLANEOUS.  

          (1)  SUCCESSORS AND ASSIGNS.  This Warrant and the rights evidenced
     hereby shall inure to the benefit of and be binding upon the successors of
     the Company and the Holder and their respective permitted assigns.  The
     provisions of this Warrant are intended to be for the benefit of all
     Holders from time to time of this Warrant, and shall be enforceable by any
     such Holder.

          (2)  HEADINGS.  The headings of the Sections of this Warrant are for
     the convenience of reference only and shall not, for any purpose, be deemed
     a part of this Warrant.

          (3)  CHOICE OF LAW.  This Warrant and the performance or breach
     thereof shall be governed by and interpreted as to substantive matters in
     accordance with the applicable laws of the State of Delaware (excluding its

                        STOCKHOLDER AND VOTING AGREEMENT


     This Stockholder and Voting Agreement ("AGREEMENT"), is made effective 
as of September 25, 1998, by and among SCIENCE APPLICATIONS INTERNATIONAL 
CORPORATION, a Delaware corporation ("SAIC"), ODS NETWORKS, INC., a Delaware 
corporation ("ODS"), and the stockholders of ODS identified below 
("STOCKHOLDERS"), who agree as follows:
     
     1.   BOARD OF DIRECTORS; OTHER.  In consideration of SAIC's investment 
in ODS pursuant to the Asset and Securities Purchase Agreement between SAIC 
and ODS of even date herewith ("A&SPA"), so long as SAIC beneficially owns, 
directly or indirectly, the lesser of (i) five percent (5%) or more of the 
outstanding shares of the common stock of ODS ("COMMON STOCK")or (ii) 
1,000,000 shares of the Common Stock (as appropriately adjusted for stock 
splits, stock dividends or other similar transactions), Stockholders and ODS 
agree to take such action as may be required to cause:

     (a)  the expansion of the number of members of the ODS Board of Directors
          from five (5) to six (6) members contemporaneously with the closing of
          the A&SPA and;

     (b)  said sixth director to be nominated by SAIC and the Stockholders to
          affirmatively support the election of such SAIC nominee;

     (c)  the ODS Board of Directors to permit a non-voting SAIC designee to
          attend and observe any meetings of the ODS Board of Directors or any
          committee thereof, provided, however, that in the event that the ODS
          Board of Directors is expanded to more than six (6) members and a
          nominee of SAIC is elected as the seventh member of the Board of
          Directors, then  upon such election, SAIC's right to have a non-voting
          designee attend the ODS Board of Directors meetings shall cease;

     (d)  SAIC to designate a nominee as the seventh director in the event the
          ODS Board of Directors is expanded to more than six (6) directors and
          the Stockholders to affirmatively support the election of such SAIC
          nominee;

     (e)  SAIC to have the right to approve the nomination by any of the
          Stockholders of additional members of the ODS Board of Directors in
          the event the ODS Board of Directors is expanded up to nine (9)
          members, which such approval shall not be unreasonably withheld or
          delayed;


                                     -1-

<PAGE>

     (f)  the Board of Directors to not be increased above nine (9) members
          without the advance written consent of the members of the Board of
          Directors nominated by SAIC;

     (g)  ODS to obtain the consent of SAIC to engage in a transaction
          involving: (i)  the sale of all or substantially all of the assets of
          ODS or the merger of ODS, other than a merger into a wholly owned
          subsidiary, in which ODS is not the surviving entity or the
          consolidation of ODS with one or more other corporations where, in any
          such event, the transaction proceeds consist, in whole or in part, of
          unregistered securities or registered securities of a company that is
          publicly traded and the average trading volume of said entity is less
          than fifteen percent (15%), on a fully-diluted basis, of SAIC's
          holdings of shares of Common Stock AND the shares of Common Stock to
          be issued upon the exercise of any warrants held by SAIC from time to
          time or (ii) any future issuance by ODS of shares of ODS stock
          representing twenty percent (20%) or more of the then outstanding
          voting stock of ODS whether  in a single transaction or a series of
          transactions between ODS and the same party or the affiliates of such
          party (in which case SAIC may condition its consent upon SAIC
          receiving preemptive rights); provided, however, that SAIC's approval
          will not be required with respect to any ODS stock (i) to be issued
          pursuant to an employee stock option plan, or (ii) to be offered to
          the public pursuant to an underwritten public offering.

     (h)  preemptive rights to be provided to SAIC with respect to any future
          offering of additional shares of ODS stock other than shares of ODS
          stock (i) any transaction approved by SAIC pursuant to this Agreement,
          (ii) to be issued pursuant to an employee stock option plan, (iii) to
          be offered to the public pursuant to an underwritten public offering,
          or (iv) issued as full or partial consideration in connection with a
          merger or acquisition by or of ODS. 

     2.   TRANSFER OF SHARES.  Nothing in this Agreement shall restrict the 
ability of the a Stockholder to sell, transfer, or otherwise dispose of any 
of the shares of Common Stock owned by them (the "STOCKHOLDER SHARES"); 
provided, however that for as long as a Stockholder owns any Common Stock 
such Stockholder shall be bound by this Agreement.

     3.   STANDSTILL. For a period of one (1) year from the date of this 
Agreement and subject to the exceptions provided in this Agreement, unless 
SAIC shall have obtained the written consent of ODS, SAIC agrees that it will 
not purchase, directly or indirectly, any additional shares of Common Stock 
(other than pursuant to the exercise of warrants issued to SAIC by ODS) 
except to retain SAIC's relative percentage of ownership of ODS stock.  
Notwithstanding the foregoing, in the event a Stockholder sells any 
Stockholder Shares, SAIC may, at any time thereafter, and without the consent 
of ODS, purchase an amount equal to the Stockholder Shares sold by the 
Stockholder(s).  


                                     -2-

<PAGE>

     4.   HOLDING PERIOD.  SAIC agrees that it will hold the Common Stock, 
warrants to purchase Common Stock or other securities of ODS issued to or 
held by SAIC pursuant to the A&SPA and any shares of Common Stock or other 
securities issued upon the exercise of the warrants (collectively, the 
"SHARES") for at least twelve (12) months from the date of this Agreement; 
provided, however, that nothing in the foregoing will be deemed to preclude 
SAIC from exercising any warrants during the twelve (12) month period 
following the date of this Agreement or to purchase additional Common Stock 
as provided for in Section 3 above. 

     5.   MISCELLANEOUS.  SAIC agrees to make appropriate personnel available 
for comment to industry analysts from time to time.

     6.   ARBITRATION OF DISPUTES.  The parties agree that any controversy or 
claim (whether such controversy or claim is based upon or sounds in statute, 
contract, tort or otherwise) arising out of or relating to this Agreement, 
any performance or dealings among the parties, or any dispute arising out of 
the interpretation or application of this Agreement, which the parties are 
not able to resolve, shall be settled exclusively by arbitration in Dallas, 
Texas by a single arbitrator pursuant to the American Arbitration 
Association's Commercial Arbitration Rules then in effect and judgment upon 
the award rendered by the arbitrator shall be entered in any court having 
jurisdiction thereof and such arbitrator shall have the authority to grant 
injunctive relief in a form similar to that which a court of law would 
otherwise grant.  The arbitrator shall be chosen from a panel of licensed 
attorneys having at least fifteen (15) years of professional experience who 
are familiar with the subject matter of this Agreement.  The arbitrator shall 
be appointed within thirty (30) days of the date the demand for arbitration 
was sent to the other party. Discovery shall be permitted in accordance with 
the Federal Rules of Civil Procedure. If an arbitration proceeding is brought 
pursuant to this Agreement, the prevailing party shall be entitled to recover 
reasonable attorneys' fees, costs and necessary disbursements incurred in 
addition to any other relief to which such party may be entitled.

     7.   CHOICE OF LAW.  The Agreement and the performance or breach thereof 
shall be governed by and interpreted as to substantive matters in accordance 
with the applicable laws of the State of Delaware (excluding its choice of 
law rules).

     8.   ASSIGNMENT.  No portion of this Agreement or any right or 
obligation hereunder can be assigned, in whole or in part, by any Stockholder 
hereto without the prior written consent of SAIC unless the assignee executes 
a document substantially similar to this Agreement, intending to be legally 
bound thereby, and delivers same to SAIC. SAIC may not assign this Agreement 
and any attempt to do so will be void and of no effect.

     9.   WAIVER.  No waiver of, no delay in the exercise of, and no omission 
to exercise any rights or remedies by any party shall be construed as a 
waiver by such party of any other rights or remedies that such party may have 
under this Agreement.

CORPORATION, a Delaware corporation ("SAIC"), and ODS NETWORKS, INC. a 
Delaware corporation ("ODS"), who agree as follows:
     
     1.   PREFERENTIAL TREATMENT.   This Agreement is not an exclusive 
dealings agreement and either party is free to do business with others with 
respect to future discrete (i.e., software programs designed to be marketed 
on an individual program basis and not as a component of another software 
program) computer network security software programs ("COMPUTER NETWORK 
SECURITY PROGRAM(S)") created by or for SAIC or ODS; provided, however, that 
in the event the SAIC executive principally responsible for managing the 
business activities of the SAIC Software and Systems Group ("SAIC-SSG") 
determines, in such executive's sole discretion, that any SAIC Computer 
Network Security Program(s) that have been created exclusively by SAIC 
employees employed within the SAIC Software and Systems Group which are 
freely transferable by SAIC to a third party (including ODS) ("SAIC-SSG 
COMPUTER NETWORK SECURITY PROGRAM(S)") should be licensed, sold, transferred 
and/or assigned to a third party on an exclusive basis solely for marketing, 
licensing or otherwise distributing such SAIC-SSG Computer Network Security 
Program(s) exclusively into  the commercial marketplace by the acquiror (the 
"CONTEMPLATED EXCLUSIVE TRANSFER"), SAIC shall submit the Contemplated 
Exclusive Transfer to ODS in reasonable detail for its consideration before 
presenting the Contemplated Exclusive Transfer to other parties.

If ODS is interested in consummating the proposed Contemplated Exclusive 
Transfer with SAIC, the parties shall negotiate in good faith the terms, 
conditions, prices and other matters related to consummation of such 
Contemplated Exclusive Transfer.  In the event the parties do not reach a 
basic agreement summarized in a writing signed by both parties within thirty 
(30) days of the date SAIC discloses the Contemplated Exclusive Transfer to 
ODS and consummate a definitive agreement concerning the Contemplated 
Exclusive Transfer within sixty (60) days of the date SAIC discloses the 
Contemplated Exclusive Transfer to ODS, SAIC will be free to deal with other 
parties with respect to the Contemplated Exclusive Transfer.  All information 
disclosed by SAIC with respect to the Contemplated Exclusive Transfer, 
including the fact that SAIC is considering a Contemplated Exclusive 
Transfer, constitutes Confidential Information subject to the provisions of 
Article 3 of this Agreement.  The provisions of this Section 1 shall apply 
only to the SAIC-SSG and not to any other business units, groups, joint 
ventures, subsidiaries or affiliates of SAIC.

     2.   EXPRESSION OF DESIRES.  The parties hereby express their mutual 
desire, but no legal obligation, to use their respective best efforts to 
generate, within two (2) years of the date of this Agreement, at least $25 
million in combined revenues from (i) sales of any ODS products and/or 
services initiated by SAIC as well as from systems integration and consulting 
projects conducted by SAIC or its subsidiaries and affiliates involving ODS 
products and/or services whether 


                                      -1-

<PAGE>

such revenues arise from this Agreement, the PartnersPlus Agreement between 
the parties of even date herewith or the respective contracts of the parties 
and/or their resellers, and (ii) sales of the computer network security 
programs presently known as the Computer Misuse and Detection System 
("CMDS"), Vulnerability Assessment System ("VAS"), Audit Monitoring and 
Intrusion Detection System ("AMIDS") and Malicious Code Detection and 
Eradication System ("MCDES") initiated by ODS and its resellers (excluding 
the sales of such products and/or services by SAIC which shall be accounted 
for in clause (i) of this Section 2); provided, however, that neither party 
shall be liable to the other nor shall there be any economic consequence if 
the parties fail to achieve this goal or even if they fail to use their best 
efforts in pursuit of this goal.  THE PARTIES RECOGNIZE THAT THE 
AFOREMENTIONED EXPRESSION OF DESIRE IS NOT LEGALLY ENFORCEABLE AND THAT 
NEITHER PARTY SHALL MAKE A CLAIM, DIRECTLY OR INDIRECTLY, AGAINST THE OTHER 
WITH RESPECT TO THE FOREGOING.

     3.   CONFIDENTIAL INFORMATION.

          3.1  The parties anticipate that under this Agreement it may be
     necessary for either party to transfer to the other information of a
     confidential and/or proprietary nature concerning the contemplated
     exclusive transfer ("CONFIDENTIAL INFORMATION").  The disclosing party
     shall clearly identify Confidential Information at the time of disclosure
     by being either marked with a legend clearly indicating that it is
     confidential or proprietary and all oral information that they reduce to
     writing and is identified as confidential or proprietary and such writing
     is given to the recipient within fifteen (15) days of the date of the oral
     disclosure.  Any information otherwise provided shall be deemed to not be
     confidential or proprietary.

          3.2  Each of the parties agree that it shall use the same efforts to
     protect such Confidential Information as are used to protect its own
     Confidential Information.  Disclosures of such Confidential Information
     shall be restricted to those individuals who are directly participating in
     the proposal and contracting efforts hereunder.

          3.3  Neither party shall make any reproductions, disclosure or use of
     such Confidential Information except in performing its obligations under
     this Agreement. 

          3.4  The limitations on reproduction, disclosure or use of
     Confidential Information shall not apply to, and neither party shall be
     liable for reproduction, disclosure or use of Confidential Information with
     respect to which any of the following conditions exist:

               (a)  If, prior to the receipt thereof under this Agreement, it
          has been developed independently by the party receiving it, or was
          lawfully known to the party receiving it, or has been lawfully
          received from other sources, including the Customer, provided such
          other source did not receive it due to a breach of this Agreement;

               (b)  If, subsequent to the receipt thereof under this Agreement,
          (i) it is published by the party furnishing it or is disclosed by the
          party furnishing it to others, including the Customer, without
          restriction, or (ii) it has been lawfully obtained by the party
          receiving it from other sources, provided such other source did not
          receive 


                                     -2-

<PAGE>

          it due to a breach of this Agreement, or (iii) if such information 
          otherwise comes within the public knowledge or becomes generally 
          known to the public; or

               (c)  If any part of the Confidential Information has been or
          hereafter shall be disclosed in a United States patent issued to the
          party furnishing the Confidential Information hereunder, then, after
          the issuance of said patent, the limitations on such Confidential
          Information as disclosed in the patent shall be only that afforded by
          the United States Patent Laws.

          3.5  Neither the execution and delivery of this Agreement, nor the
     furnishing of any Confidential Information by either party shall be
     construed as granting to the other party either expressly, by implication,
     estoppel, or otherwise, any license under any invention, patent, trademark,
     or copyright now or hereafter owned or controlled by the party furnishing
     same.

          3.6  Each of the parties shall identify a person responsible for
     receipt of Confidential Information subject to this Article.

     4.   INDEPENDENT CONTRACTORS.  The parties hereto intend that the 
relationship between them created by this Agreement shall be that of 
independent contractors and that the relationship shall continue as such as 
long as this Agreement remains in effect. Nothing contained in this Agreement 
shall be construed to constitute either party as a partner, employee or agent 
of the other, and no employee or agent of either party shall be or be deemed 
to be the employee or agent of the other.

     5.   LIMITATION OF LIABILITY.  IN NO EVENT SHALL EITHER PARTY BE LIABLE 
TO ONE ANOTHER OR TO ANY THIRD PARTY IN CONTRACT, TORT OR OTHERWISE FOR 
INCIDENTAL, CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES, INCLUDING WITHOUT 
LIMITATION, LOST BUSINESS PROFITS OR LOSS, DAMAGE OR DESTRUCTION OF DATA.

     6.   TERMINATION.  This Agreement shall have an initial term of two (2) 
years.  Thereafter either party shall have the right to terminate this 
Agreement at any time, with or without cause, effective upon thirty (30) 
day's written notice to the other party.  The termination of this Agreement 
shall not terminate the obligations under Section 3 hereof or impact any 
transactions entered by the parties previous thereto which shall continue 
according to the provisions established by the parties for same. 

     7.   ARBITRATION OF DISPUTES.  The parties agree that any controversy or 
claim (whether such controversy or claim is based upon or sounds in statute, 
contract, tort or otherwise) arising out of or relating to this Agreement, 
any performance or dealings between the parties, or any dispute arising out 
of the interpretation or application of this Agreement, which the parties are 
not able to resolve, shall be settled exclusively by arbitration in Dallas, 
Texas by a single arbitrator pursuant to the American Arbitration 
Association's Commercial Arbitration Rules then in effect and judgment upon 
the award rendered by the arbitrator shall be entered in any court having 
jurisdiction thereof and such arbitrator shall have the authority to grant 
injunctive relief in a form similar to that 


                                     -3-

<PAGE>

which a court of law would otherwise grant.  The arbitrator shall be chosen 
from a panel of licensed attorneys having at least fifteen (15) years of 
professional experience who are familiar with the subject matter of this 
Agreement.  The arbitrator shall be appointed within thirty (30) days of the 
date the demand for arbitration was sent to the other party. Discovery shall 
be permitted in accordance with the Federal Rules of Civil Procedure. If an 
arbitration proceeding is brought pursuant to this Agreement, the prevailing 
party shall be entitled to recover reasonable attorneys' fees, costs and 
necessary disbursements incurred in addition to any other relief to which 
such party may be entitled.

     8.   CHOICE OF LAW.  The Agreement and the performance or breach thereof 
shall be governed by and interpreted as to substantive matters in accordance 
with the applicable laws of the State of Delaware (excluding its choice of 
law rules).

     9.   ASSIGNMENT.  No portion of this Agreement or any right or 
obligation hereunder can be assigned, in whole or in part, by either party 
hereto without the prior written consent of the other party.

     10.  WAIVER.  No waiver of, no delay in the exercise of, and no omission 
to exercise any rights or remedies by either party shall be construed as a 
waiver by such party of any other rights or remedies that such party may have 
under this Agreement.

     11.  NOTICE.  Unless otherwise specified herein, any notice required or 
permitted to be given under this Agreement shall be sufficient, if in 
writing, and shall be deemed to be fully given if personally delivered, if 
sent by registered mail, by facsimile with an original copy by regular mail, 
or by telex with receipt acknowledged, to the following addresses:

     MCDES or VAS nor (b) any enhancements, modifications or customization made
     for any government entities that have prohibitions relating to transfer of
     such enhancements, modifications or customization, whether by contract or
     by statute or federal regulation, until such prohibitions are lifted.  Any

     invoicing the United States Government, with respect to any Conveyed Items
     and/or any Improvements or any portion thereof. ODS shall not deliberately
     bundle or market Conveyed Items and/or Improvements in a manner that is
     designed to or that has the effect of lowering the royalty fees to be paid
     by ODS to SAIC. If ODS or SAIC become aware of such effect, and ODS is

<PAGE>

     warranty period from improper installation, misuse, accident or

               12.1.1    Third party items purchased through ODS but not
               incorporated into the Products will carry that item's warranty as
               provided by the original manufacturer.

     12.2   SOFTWARE.

               12.2.1    ODS warrants that Licensed Software (excepting Conveyed
               Items), for twelve (12) months from the date of shipment, in the
               unaltered form provided by ODS, will (i) meet the Specifications
               for such Licensed Software and (ii) will interface and operate
               with Equipment specified for such Licensed Software.

               12.2.2    Other than the Conveyed Items, ODS represents it has

               Information to grant the licenses to SAIC. 

     12.3   SOLE OBLIGATION.  ODS' SOLE OBLIGATION UNDER THIS WARRANTY
     PROVISION WILL BE TO PROVIDE THE REMEDIES DESCRIBED IN THIS ARTICLE 12.
     EXCEPT FOR THE EXPRESSED WARRANTIES STATED IN THIS ARTICLE 12, ODS
     DISCLAIMS ALL WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, WITH RESPECT TO
     ITS PRODUCTS AND SERVICES (INCLUDING CONVEYED ITEMS), INCLUDING WITHOUT
     LIMITATION, ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
     PURPOSE, OR ARISING FROM A COURSE OF DEALING, USAGE OR TRADE PRACTICE. 

     12.4   MEDIA WARRANTY.  ODS warrants the tapes, diskettes or other media
     to be free of defects in materials and workmanship under normal use for 90
     days from the Commencement Date.

     reasonable measures to identify and eliminate, any viruses from any media

     (excepting Conveyed Items) hereunder; for purposes of this section, a
     "virus" is an extraneous and undocumented potentially damaging code or
     program the effect of which may be the destruction of computer data or the
     permanent or temporary disabling of a computer system, including but not
     limited to "time bombs," "logic bombs," and other computer viruses.

     disabling devices or other codes, instructions or devices which may disable
     the Products or other software or erase or corrupt data.

     12.7   SERVICES WARRANTY.  ODS warrants that its technical support,
     training and consulting services will be performed consistent with
     generally accepted industry standards.  This warranty shall be valid for 90
     days from performance of service.

     12.8   YEAR 2000.  ODS warrants that each Product (excepting Conveyed
     Items) will promptly and properly perform all of the functions described in
     the Specifications without any degradation in the performance or features
     of the Product before, upon the occurrence of, during and after calendar
     year 2000, it being understood and agreed that this warranty provision will
     expressly continue until December 31, 2002 whether or not software or
     hardware maintenance services are purchased by SAIC (the "Year 2000
     Warranty").  This warranty will continue until December 31, 2002.  In the
     event of ODS' breach of this Year 2000 Warranty, ODS will repair or replace
     any nonconforming component, at ODS' expense within five (5) days of ODS'
     receipt of a written request from SAIC.  SAIC may require ODS to refund all
     of the amounts paid to ODS for Products distributed by SAIC and, with
     respect to Products used internally by SAIC, the amount equal to all
     payments to ODS depreciated on a straight-line basis over five years for
     nonconforming Product returned to ODS by SAIC under this Agreement within
     ten (10) days after the date SAIC determines that the Product does not
     perform as required hereunder and ODS has not cured the nonconformity in
     the time permitted. Notwithstanding the foregoing, SAIC acknowledges and
     agrees that (i) the Product does not identify or remedy Year 2000 problems
     in third party systems or other products or applications not provided or
     supplied by ODS and (ii) the Product operates with the date information it
     receives; thus, if incorrect date information is provided by the user, the
     system or from any other external product or other source, this information
     will be used by the Product as received. The foregoing Year 2000 Warranty
     of ODS shall not apply to Year 2000 problems caused by such external
     sources.

     12.9   NO CONFLICT.  ODS represents and warrants that it is under no
     obligation or restriction, nor will it assume any such obligation or
     restriction that does or would in any way interfere or conflict with, or
     that does or would present a conflict of interest concerning, the services
     to be performed or Products to be delivered by ODS under this Agreement.

13.  OUT-OF-WARRANTY REPAIR

     13.1   ODS shall provide out-of-warranty repair and refurbishment services
     for Equipment at the then prevailing rates if such Equipment is not covered
     by an ODS service and support program pursuant to Section 11.3 of this
     Agreement.  SAIC shall issue an Order authorizing repair and/or
     refurbishment and will ship Products to ODS freight prepaid.  ODS shall
     complete services and return Products to SAIC within thirty (30) days of
     receipt.  SAIC shall have risk of loss until returned Products are received
     by ODS.  ODS shall have risk of loss from receipt of returned Products
     until repaired or replaced Products are received by SAIC.

               13.1.1    ODS warrants repaired Equipment will conform to
               applicable Specifications and be free from defects in material
               and workmanship for a period of ninety (90) days from ODS
               shipment.

14.  PROPRIETARY INFORMATION

                                      -9-
<PAGE>

     14.1   All Proprietary Information disclosed by either party to the other
     in tangible form shall be clearly marked "Proprietary", "Confidential", or
     "Restricted" or with a similar legend.  If Proprietary Information is
     disclosed in other than tangible form, then the disclosing party shall
     inform the receiving party that the information is Proprietary Information
     at the time of disclosure and shall describe such information in writing
     delivered to the receiving party within fifteen (15) days after disclosure
     to be entitled to enforce the rights and obligations under this section. 

     14.2   Neither party shall disclose any Proprietary Information which it
     does not have the right to disclose and shall defend and indemnify the
     receiving party against any claim or liability resulting from breach of
     this obligation.

     14.3   The disclosing party shall retain title to its Proprietary
     Information.

     14.4   Proprietary Information shall be protected against disclosure to
     unauthorized persons using the same standard of care as the receiving party
     uses to protect its own Proprietary Information of equivalent importance,
     but in no event less than reasonable care.

     14.5   The obligation not to disclose Proprietary Information shall not
     apply to Proprietary Information: (i) already known by or available to the
     receiving party at the time of disclosure; (ii) independently developed by
     the receiving party or an affiliated entity and not derived from any
     Proprietary Information supplied by the disclosing party; (iii) known or
     available to the public, or which may become available to the public,
     except where such knowledge or availability is the result of an
     unauthorized disclosure by the receiving party; (iv) disclosed to the
     receiving party or to an affiliated entity without a nondisclosure
     restriction by a third party having the right to disclose; (v) made
     available by the disclosing party to a third party without a nondisclosure 
     restriction; or (vi) to the extent required to be disclosed by law,
     regulation, court order or other legal process provided the disclosing
     party is given prior written notice and the opportunity to intervene to
     protect its interest in nondisclosure. Notwithstanding the above and
     subject to the provisions of the A&SPA and the agreements provided for
     therein, ODS Proprietary Information includes ODS' rights in the Conveyed
     Items and Improvements created by ODS or any portion thereof subject to
     SAIC retaining the right to freely use for any purpose the residuals
     resulting from access to or work with any Conveyed Items or Improvements
     created by SAIC so long as such residuals are not used to create computer
     programs that perform substantially the same functions in substantially the
     same way, to achieve the same or substantially the same result as the
     Conveyed Items or Improvements created by ODS.  The term "residuals" means
     technical information related to any Conveyed Items or Improvements created
     by SAIC in non-tangible form, which may be retained by persons who have had
     access to any Conveyed Items or Improvements created by SAIC, including
     ideas, concepts, know-how, or techniques contained therein. Neither party
     shall have any obligation to limit or restrict the assignment of such
     persons or to pay royalties for any work resulting from the use of
     residuals. Nothing in the foregoing shall, however, be deemed to be the
     grant of a license under the copyrights and patent application conveyed
     under the A&SPA.

     code, structure, algorithms or ideas underlying the Products except as may
     be necessary to achieve interoperability between the Software and another
     independently created software program, (ii) rent, lease or otherwise
     provide temporary access to a Product, (iii) take any action contrary to
     ODS' or its licensors' end-user license agreement (which ODS shall provide

     under this Agreement (iv) copy, alter or modify the Products except as may
     be necessary to achieve interoperability between the Products and another
     independently created software program or (v) allow others to do any of the
     foregoing.

     15.2   SAIC will be responsible for all technical support of its
     customers; ODS will provide technical support and assistance to SAIC
     pursuant to ODS's standard support and maintenance terms and conditions. 
     In its distribution efforts, SAIC will use the then current names, marks
     and designations used by ODS for the Products ("Marks") but will not
     represent or imply that it is ODS or is a part of ODS; provided that all
     advertisements and promotional materials, packaging and anything else
     bearing a Mark shall identify ODS as the Mark owner and Product
     manufacturer and shall be subject to prior written approval of ODS, which
     approval shall not be unreasonably withheld, and, provided further, that no
     other right to use any name or designation is granted by this Agreement. 
     SAIC also agrees not to use or contest, during or after the term of this
     Agreement, any name, mark or designation used by ODS anywhere in the world
     (or any name, mark or designation similar thereto).  SAIC acknowledges and
     agrees that all use of the Marks by SAIC shall inure to the benefit of ODS.

     15.3   SAIC agrees to keep ODS informed as to any problems encountered
     with the Products and any resolutions arrived at for those problems, and to
     communicate promptly to ODS any and all modifications, design changes or
     improvements of the Products suggested by any customer, employee or agent. 

     15.4   SAIC agrees in all cases, to deliver all components of the Products
     to End-Users thereof; such components shall include, without limitation,
     software disks or other media bearing labels, ODS's or its licensors' end
     user manuals and documentation, ODS's or its licensors' end user license
     agreements and, at the option of SAIC, advertising and promotional
     materials supplied by ODS.

     15.5   SAIC agrees to keep for three (3) years after termination of this
     Agreement records of all Product sales and customers sufficient to
     adequately administer a recall of any Product and to fully cooperate in any
     decision by ODS to recall, retrieve and/or replace any Product.

16.  PATENT, COPYRIGHT AND TRADE SECRET INDEMNIFICATION

     16.1   INDEMNIFICATION FOR INFRINGEMENT.  For the purposes of this Article
     16, the term "Products" shall not include any "Conveyed Items." To the
     extent not proximately caused 

                                      -11-
<PAGE>

     by SAIC, ODS, at its own expense, will defend, indemnify and hold SAIC 
     and its directors, officers, employees and agents harmless against claims 
     or actions (and all related costs and expenses as and when incurred) 
     alleging that Products infringe a patent, copyright or misappropriate 
     trade secrets or other intellectual property rights of a third party 
     provided SAIC (i) gives ODS prompt written notice of the claim or action, 
     (ii) permits ODS to defend or settle such claim or action and (iii) 
     provides reasonable assistance to ODS in defending or settling the claim 
     or action.  SAIC reserves the right, at its expense, to participate in 
     defense of any claim or action through counsel selected by SAIC.  SAIC's 
     rights under this Article extend to ODS Products only and do not extend 
     to third-party items not incorporated into the Products.  The foregoing 
     obligation of ODS does not apply with respect to Products (i) specially 
     made by ODS to the specifications of SAIC, (ii) which are modified by 
     other than ODS after their shipment by ODS if the alleged infringement 
     relates to such modification, (iii) combined by parties other than ODS 
     with other products, processes or materials where the alleged 
     infringement relates to such combination, or (iv) where SAIC continues 
     allegedly infringing activity after being notified thereof or after being 
     informed by ODS of the availability of modifications (at no expense to 
     SAIC) that would have avoided the infringement.
     
     16.2   INFRINGEMENT.  As to any Product, which is or, in the opinion of
     ODS, may become subject to a claim of infringement or misappropriation and
     to the extent not proximately and directly caused by SAIC, ODS may elect to
     (i) obtain the right for continued sale and/or use by SAIC, or (ii) replace
     or modify the Product to avoid such claim.  If neither of the
     aforementioned are completed promptly, ODS promptly shall refund all
     amounts paid by SAIC with respect to Products distributed by SAIC and, with
     respect to Products used internally by SAIC, the depreciated amount on a
     straight-line five year basis, relating to the infringing Product, in
     either case, such refund shall be paid to SAIC within ten (10) days after
     the return of the Products to ODS.

17.  TERMINATION AND CANCELLATION

     17.1   ODS DEFAULT.  This Agreement or any Order(s), in whole or in part,
     shall be deemed canceled for default of ODS if a material default is not

     material default and specifying the Agreement or the Order(s) to be
     canceled.

     17.2   SAIC DEFAULT.  This Agreement or any Order(s), in whole or in part,

18.  INDEMNIFICATION AND INSURANCE

     18.1   INDEMNIFICATION.  ODS agrees to indemnify SAIC as to any and all

     performing this Agreement or from Products (excepting Conveyed Items)
     delivered by ODS under this Agreement.

19.  MOST FAVORED CUSTOMER

     ODS represents and warrants that the prices, discounts, Product offerings,
     license provisions and availability, services and other provisions having a
     financial impact (e.g., a no-charge extended warranty, a no-charge
     extension of service availability, etc.) ("PROVISIONS") of this Agreement
     are at least as favorable as those offered by ODS to any other customer of
     ODS or offered by ODS to a prospective customer.  ODS agrees to
     automatically extend any more favorable Provisions to SAIC on and after the
     date such provisions are offered by ODS to any customer of ODS or to a
     prospective customer of ODS subject to the exceptions set forth in the
     following sentence. The terms of this Agreement shall be deemed to have
     been modified by such more favorable Provisions subject to the following
     exceptions: (i) limited special promotions to select customers or potential
     customers and (ii) unusually large discounts or variance in terms related
     to select Product offerings to select customers or 

                                      -13-
<PAGE>

     potential customers designed to encourage such customers to purchase, or 
     purchase additional, products from ODS (collectively referred to as 
     "SPECIAL OFFERINGS"). ODS hereby authorizes SAIC to review its books and 
     records on an annual basis to verify ODS' compliance with this section.  
     Notwithstanding the foregoing, whenever ODS knows or has reason to know 
     that SAIC and another customer of ODS or a prospective customer of ODS 
     are competing for the same project, request for proposal or other 
     contract, ODS shall extend the same or more favorable Provisions to SAIC, 
     even if a Special Offering is involved, it being the intention of the 
     parties that SAIC shall never be placed at a competitive disadvantage in 
     dealing with the Products.

20.  DISPUTE RESOLUTION

     20.1   ARBITRATION.  The parties agree that any controversy or claim
     (whether such controversy or claim is based upon or sounds in statute,
     contract, tort or otherwise) arising out of or relating to this Agreement,
     any performance or dealings between the parties, or any dispute arising out
     of the interpretation or application of this Agreement, which the parties
     are not able to resolve, shall be settled exclusively by arbitration in
     Dallas, Texas by a single arbitrator pursuant to the American Arbitration
     Association's Commercial Arbitration Rules then in effect and judgment upon
     the award rendered by the arbitrator shall be entered in any court having
     jurisdiction thereof and such arbitrator shall have the authority to grant
     injunctive relief in a form similar to that which a court of law would
     otherwise grant.  The arbitrator shall be chosen from a panel of licensed
     attorneys having at least fifteen (15) years of professional experience who
     are familiar with the subject matter of this Agreement.  The arbitrator
     shall be appointed within thirty (30) days of the date the demand for
     arbitration was sent to the other party. Discovery shall be permitted in
     accordance with the Federal Rules of Civil Procedure. If an arbitration
     proceeding is brought pursuant to this Agreement, the prevailing party
     shall be entitled to recover reasonable attorneys' fees, costs and
     necessary disbursements incurred in addition to any other relief to which
     such party may be entitled.

     20.2   STATUTE OF LIMITATIONS.  No proceeding, regardless of its form,
     arising out of or in relation to this Agreement, its making or performance,
     may be commenced by either party more than two (2) years after the cause of
     action has accrued.

21.  LIMITATION OF LIABILITY

     21.1   IN NO EVENT SHALL EITHER PARTY BE LIABLE TO ONE ANOTHER OR TO ANY
     THIRD PARTY IN CONTRACT, TORT OR OTHERWISE FOR INCIDENTAL, CONSEQUENTIAL,
     SPECIAL OR INDIRECT DAMAGES, INCLUDING WITHOUT LIMITATION, LOST BUSINESS
     PROFITS OR LOSS, DAMAGE OR DESTRUCTION OF DATA, EVEN IF THE PARTY CAUSING
     THE DAMAGE HAS BEEN ADVISED AS TO THE POSSIBILITY OF SAME.

22.  FINDER'S FEES

                                      -14-
<PAGE>

     During the first two (2) years following the date of this Agreement
     ("FINDER'S FEE PERIOD"), if, as and when SAIC identifies an opportunity
     whereby ODS may enter a business transaction with a prospective customer
     concerning any of the Conveyed Items, SAIC may notify ODS in writing as to
     the opportunity and will provide ODS with a reasonable description of the
     opportunity, including the names of appropriate contacts, general scope of
     the opportunity envisioned and such other information as SAIC may possess
     concerning the opportunity (the "SAIC IDENTIFIED PROSPECT"). If agreed upon
     by SAIC and ODS with respect to an SAIC Identified Prospect, SAIC will help
     in scheduling meetings with the SAIC Identified Prospect's personnel,
     attending such meetings as requested by ODS, preparing reports as
     reasonably requested by ODS, helping in the creation of proposals by ODS,
     and such other things as ODS and SAIC mutually agree upon, however, ODS
     acknowledges that SAIC is not obligated to undertake any of the foregoing
     to receive the fees provided herein. ODS will solely determine the terms of
     any offering submitted to an SAIC Identified Prospect. In return for SAIC's
     advising ODS of an SAIC Identified Prospect with which ODS enters a
     business transaction involving the purchase, license or other acquisition
     of any of the Conveyed Items by the SAIC Identified Prospect within one (1)
     year of the date of disclosure to ODS of the identity of the SAIC
     Identified Prospect by SAIC, ODS agrees to pay SAIC a commission of 
     [***] of the amount invoiced by ODS to the SAIC Identified Prospect 
     with respect to any of the Conveyed Items that ODS furnishes to or for 
     the SAIC Identified Prospect during the Finder's Fee Period and during 
     the six (6) month period following thereafter (the "FINDER'S FEE").  
     ODS will pay the Finder's Fee to SAIC within ninety (90) days after the 
     date ODS invoices the SAIC Identified Prospect.  It is agreed by the 
     parties that the Finder's Fees will apply to transactions between ODS 
     or SAIC with respect to [***] that are outstanding as of the date of this 
     Agreement. No royalty as provided in the SRGBLA will be payable by ODS 
     to SAIC with respect to any of the Conveyed Items when a Finder's Fee 
     is paid to SAIC hereunder.  Finder's Fees are not applicable to 
     Products other than the Conveyed Items.  ODS shall not deliberately 
     bundle or market Conveyed Items in a manner that is designed to or that 
     has the effect of lowering the Finder's Fees to be paid by ODS to SAIC. 
     If ODS or SAIC become aware of such effect, and ODS is notified by SAIC 
     of such effect or in the event ODS otherwise becomes aware of such 
     effect, ODS shall immediately take appropriate corrective action. Upon 
     providing reasonable advance notice to ODS, SAIC shall be entitled to 
     inspect ODS' books and records during ODS' normal business hours to 
     audit ODS' compliance with this provision for Finder's Fees. 

23.  GENERAL

     23.1   FORCE MAJEURE.  Neither party shall be liable for delays in
     performance if such delay is caused by strike, riots, wars, government
     regulations, fire, floods, acts of God nor other similar causes beyond its
     control provided the other party is given prompt notice of any such delay.
