[SAIC (R) LOGO] SCIENCE APPLICATIONS
            INTERNATIONAL CORPORATION
            An Employee-Owned Company       PURCHASE CONTRACT NUMBER: 4400078647

SECTION A - SPECIAL AGREEMENTS AND OTHER IMPORTANT PROVISIONS AND NOTIFICATIONS

A.1   DEFINITIONS

      a.    The term "Lead Systems Integrator" or "LSI" refers to The Boeing
            Company and Science Applications International Corporation,
            responsible to the U.S. Government under the Boeing/Government prime
            Agreement for the Systems Development and Demonstration (SDD) phase
            of the Future Combat System (FCS) Program.

      b.    Unless otherwise specified, the terms "contract," "subcontract,"
            "purchase order," or "purchase contract" are synonymous.

      c.    An "administrative change" means a unilateral contract change, in
            writing by the SAIC Procurement Agent, that does not affect the
            substantive rights of the contracting parties.

      d.    The terms "Buyer's authorized Procurement Representative" and
            "Buyer's authorized Procurement Agent" are synonymous.

      e.    Unless otherwise specified, "prime agreement," "Agreement," "Other
            Transaction Agreement," or "OTA" mean the Future Combat Systems
            (FCS) System Development and Demonstration (SDD) Phase agreement
            between the Government and The Boeing Company.

      f.    A "unilateral change" is a contract change that is signed only by
            Buyer's authorized Procurement Agent. Unilateral changes are used,
            for example, to make: (1) administrative changes; (2) Issue change
            orders or change notices authorized by the Changes clause; (3) Make
            changes authorized by clauses other than a changes clause (e.g.,
            Property clause, Options clause, Limitation of Funds clause, or
            Suspension of Work clause); and (4) Issue termination notices.

      g.    A "bilateral change" is a contract change that is signed by Seller
            and Buyer's authorized Procurement Agent. Bilateral changes are used
            to: (1) Make negotiated equitable adjustments resulting from the
            issuance of a change order or Change Notice; (2) Definitize letter
            contracts; and (3) Reflect other agreements of the parties modifying
            the terms of contracts. A Supplemental Agreement is a bilateral
            contract change.

      h.    All reference within this subcontract to GP4 "The Boeing Company
            General Provisions (Cost Reimbursement Contract Under Government
            Prime Contract)" shall be considered as SAIC General Provisions for
            the purpose of this subcontract only and in no way sets a precedence
            for any other subcontracts Seller may currently have or enter into
            in the future with The Boeing Company or SAIC.

A.2   ORDER OF PRECEDENCE

      Any inconsistency in this contract shall be resolved by giving precedence
      in the following order:

      1.    Clause 5068 (Government Contract Requirements) set forth in Section
            I and Section H clauses with "(PRIME FLOWDOWN)" in clause title

      2.    Sections A through G (excluding Section C - Statement of
            Work/Specifications)

      3.    Section H (Special Provisions)

      4.    Section I (General Provisions)

      5.    Section C (Statement of Work/Specifications)

      6.    All other documents, exhibits and attachments set forth in Section J

A.3   CONTRACT CHANGES AND CONFORMING CONTRACT

      a.    Buyer's authorized Procurement Agent is the only person empowered to
            execute contract changes on behalf of Buyer. Buyer-issued contract
            changes --

            (1)   will be sequentially numbered, e.g., contract change no. 001,
                  002, 003, etc.;

            (2)   will define the type of contract change, e.g.,
                  Unilateral/Undefinitive Change Notice, Unilateral Funding
                  Order, Supplemental Agreement ;

            (3)   will provide new/revised contract attachments/exhibits, as
                  applicable; and

            (4)   will include a replacement or new contract page when there is
                  a change in the contract text or terms except for undefinitive
                  contract changes.

            Undefinitive contract changes such as a Change Notice issued under
            the Changes clause will not be reflected in the text of a
            replacement contract page until definitized by Supplemental
            Agreement.

      b.    Replacement contract pages will identify the specific text change(s)
            by revision bar (vertical line) placed in the margin of the
            replacement page. AT BUYER'S OPTION, further DELINEATION OF
            CHANGE(S) CAN BE MADE BY SHOWING strikethroughs (for deleted text)
            and italics or BOLDED PRINT (FOR ADDED TEXT). Each replacement page
            will identify at the top of the page (or header) the Contract Change
            Number and date. By issuing the replacement contract page, Seller
            will possess a complete conforming text of the contract.

      c.    When the contract change adds new text requiring additional contract
            pages, Buyer will retain the original contract page number with
            added pages designated by letter, e.g., page 5 adds pages 5a, 5b,
            5c, etc. A new contract page will be identified in the same manner
            as the replacement contract page described above, i.e., Contract
            Change Number and date.

A.4   CONTRACT CHANGE SUMMARY LIST

      The table below provides a descriptive list of the Contract Changes issued
      under the contract. Buyer will issue an updated summary table from
      time-to-time by way of an administrative contract change as the number of
      contract change documents accumulate.

      NOTE: THE BELOW TABLE IS INITIALLY BLANK, RESERVING SPACE AND FORMAT FOR
      RECORDING FUTURE CHANGE ENTRIES.

SECTION B - GOODS/SERVICES AND PRICES/COSTS

B.1   CONTRACT TYPE

      a.    This contract is a cost-plus-fixed-fee (CPFF). A CPFF contract is a
            cost-reimbursement contract that provides for payment to the Seller
            of a negotiated fee that is fixed at the inception of the contract.
            The fixed fee does not vary with actual cost, but may be adjusted as
            a result of changes in the work to be performed under the contract.
            The CPFF contract may take one of two basic forms -- completion or
            term. This contract may use both forms. The CPFF contract type only
            applies to the task order CLIN specified below.

      b.    Applicable to the Contract Line Item Numbers (CLINs) specified below
            are cost underrun fee provisions. Similar to cost-plus-incentive-fee
            (CPIF) contracting, but only applicable to cost underruns, these
            cost underrun incentive fee provisions reward the Seller with
            additional fee when performing a cost underrun, and satisfying the
            requirements of the SOW pursuant to the inspection and acceptance
            terms or Section E. The incentive fee provisions are defined by the
            Fee Plan set forth in Section J.

B.2   STATEMENT OF REQUIREMENTS AND TOTAL CONTRACT VALUE

      a.    Seller shall, in accordance with the terms and conditions set forth
            herein, furnish necessary, qualified personnel, services, travel,
            facilities, and materials (except those specifically designated to
            be furnished by Buyer or Government), and do all things necessary
            and incidental to complete the contractual effort in accordance with
            the Statement of Work/Specification set forth in Section C and the

SECTION G - CONTRACT ADMINISTRATION DATA

G.1   INVOICE AND PAYMENT

      The overall reimbursement structure of this contract is Cost-Plus-Fix-Fee,
      as defined in Section B.1, and applies to all CLINs. In consideration for
      performing contract activities, Seller shall invoice and receive Buyer
      payments in accordance with the provisions of this Section G, and the
      Invoice and Payment article of GP4 "The Boeing Company General Provisions
      (Cost Reimbursement Contract Under Government Prime Contract)."

G.2   PAYMENT OF FIXED FEE - ALL NON-TASK ORDER CLINs

      a.    Subject to the "Fixed Fee" clause of GP4 "The Boeing Company General
            Provisions (Cost Reimbursement Contract Under Government Prime),"
            Seller will be paid in installments at the time of each provisional
            payment on account of the allowable costs. The amount of fixed fee
            paid will be based on the ratio that the Seller's incurred allowable
            costs bear to the total estimated cost. The method of fee payment is
            as follows (percent completion method based on cost):

            Total payable fixed fee by CLIN is equal to the total CLIN fixed fee
            amount set forth in the contract multiplied by the quotient of total
            incurred/expended CLIN cost divided by total estimated CLIN cost
            specified in the contract:

<TABLE>
<S>                 <C>                         <C>
  Total Payable   =  [Total CLIN Fixed Fee]  X   [Total Incurred/Expended CLIN Cost]
                                                ------------------------------------
Fixed Fee by CLIN   [Specified in Contract]     [Total Estimated CLIN Cost Specified
                                                            In Contract]
</TABLE>

            Total payable CLIN fixed fee (calculated from above) minus (previous
            paid fixed fee) equals the current fixed fee payment installment.

      b.    For each non-task order CLIN, if the Seller does not successfully
            complete the stated goals, targets and end-product deliveries of the
            Statement of Work required by the contract, and Buyer does not
            authorize more effort with an increase in cost, the fixed fee of the
            applicable CLIN shall be equitably adjusted downward. However, if
            Seller completes the stated goals, targets and end-product
            deliveries of the Statement of Work required by contract, and under
            runs the costs, the Seller is entitled to the entire fixed fee for
            the applicable CLIN.

G.3   COST UNDERRUN INCENTIVE -- ALL NON-TASK ORDER CLINs

      In addition to the payable fixed fee, Seller may earn additional fee in
      accordance with the enclosure entitled "Underrun Fee Provisions," set
      forth in Section J.

G.4   PAYMENT OF FIXED FEE - CPFF (LOE) TASK ORDER CLINs (0006 ONLY)

      a.    Subject to the "Fixed Fee" clause of GP4 "The Boeing Company General
            Provisions (Cost Reimbursement Contract Under Government Prime),"
            the fixed fee for each task order authorized in accordance with the
            Section H clause entitled "Authorization and Administration Of CPFF
            Level-Of-Effort (LOE) Task Orders," shall be paid -

               -     at the end of the period of performance (expiration
                     date) set forth in the task order;

               -     after Buyer's receipt of an acceptable invoice; and

               -     after Buyer's acceptance of Seller's "Certificate of
                     Utilization of Hours" and the task order effort

      b.    In the event the Seller does not expend the specified LOE (minimum
            quantity of direct labor hours) required by the authorized task
            order within the specified time period, the task order fixed fee
            shall be equitably adjusted downward. However, if Seller expends the
            specified LOE within the specified time period and under runs the
            task order costs, the Seller is entitled to the entire fixed fee of
            the task order.

G.5   PAYMENT OF FIXED FEE - CPFF (COMPLETION) TASK ORDER CLINs (0006 ONLY)

      a.    Subject to the "Fixed Fee" clause of GP4 "The Boeing Company General
            Provisions (Cost Reimbursement Contract Under Government Prime),"
            the fixed fee for each task order authorized in accordance with the
            Section H clause entitled "Authorization and Administration Of CPFF
            Completion Task Orders," shall be paid in installments no more than
            once every two weeks upon receipt of an acceptable invoice, and at
            the same time Seller's task order costs are invoiced;

            Calculation of fixed fee will be based upon the ratio of cumulative
            task order costs incurred, to date, to the total estimated task
            order costs. Example:

<TABLE>
<S>                    <C>                          <C>
Total Payable Task =     [Total Fixed Fee]      X   [Total Incurred/Expended Task Order Cost]
                                                      ---------------------------------------
   Order Fixed Fee     [Specified in Task Order]        [Total Estimated Cost Specified in
                                                                 Task Order]
</TABLE>

            Total payable fixed fee (calculated from above) minus (previous paid
            fixed fee) equals the current fixed fee payment installment.

      b.    The Buyer will not pay the last task order invoice until after
            Buyer's acceptance of Seller's "Certificate of Completion" and the
            task order effort.

      c.    In the event the Seller does not successfully complete the stated
            goals, targets and end-product deliveries of the Statement of Work
            required by the task order, and the Buyer does not authorize more
            effort with an increase in cost, the task order fixed fee shall be
            equitably adjusted downward. However, if Seller completes the task
            order, submits an acceptable Certificate of Completion and under
            runs the task order costs, the Seller is entitled to the entire
            fixed fee of the task order.

            (2) If the proposed price is for a commercial item, Seller shall
                provide, at a minimum, information on prices at which the same
                or similar items have previously been sold, leased or licensed
                or had been offered for sale, lease or license that is adequate
                for evaluating the reasonableness of the price of the
                modification. Such information may include:

                (a)  For catalog items, a copy of, or identification of the
                     catalog and its date, or the appropriate pages for the

                     Also explain the basis of each proposed price and its
                     relationship to the established catalog price, including

                (b)  For market-priced items, the source and date or period of
                     the market quotation or other basis for market price, the

                authorized Government representative, the right to examine, at
                any time the books, records, documents, or other directly
                pertinent records to verify the reasonableness of price for (1)
                or (2) above. For items priced using catalog or market prices,
                or law or regulation, access does not extend to cost or profit
                information or other data relevant solely to Seller's

            such modifications are within the general scope of the contract, but
            may not be initiated or authorized by Buyer without a net cost
            increase and/or schedule change to the contract, Buyer's authorized
            Procurement Agent may request Seller to prepare and submit a change
            proposal for the contemplated modifications. Upon receipt of a
            written request from Buyer's authorized Procurement Agent and in
            accordance with the Procurement Agent's instructions, Seller shall
            prepare and submit a proposal for the contemplated contract change
            in compliance with one of the two types of cost proposals requested
            by Buyer, and described in this clause.

      b.    Reserved

      c.    Submission of Firm Cost Proposals. When requested by Buyer, Seller
            shall prepare the firm cost proposal in such form and substance as
            to represent a request for contract adjustment pursuant to Section
            H.10 "Modifications" and the "Changes" article of GP4 "The Boeing
            Company General Provisions (Cost Reimbursement Contract Under
            Government Prime Contract)"; and unless authorized by Buyer's
            authorized Procurement Agent, will normally be received prior to the
            issuance of Buyer's written authorization for Seller to proceed with
            the modified work incorporated by the change. If Buyer decides to
            authorize the change, the firm cost proposal shall be cited in
            Buyer's unilateral contract modification, and upon its issuance,
            shall be a binding part of the contract pending definitization of
            the Equitable Adjustment. This firm cost proposal is the maximum
            adjustment to be made in the total contract price; i.e., target
            cost, estimated cost, target fee or fixed fee, as appropriate for
            the type of contract; or in the delivery schedule (or time of
            performance) by reason of the change. In no event shall the
            definitive Equitable Adjustment exceed the limitations established
            with the exception of adjustments affected by rate changes which
            have been approved by the Government subsequent to the submittal
            date of the firm cost proposal. This exception applies provided that
            the original firm cost proposal submittal utilized Government
            approved rates. Firm cost proposals submitted by Seller which
            require modification because of redirection by Buyer's authorized
            Procurement Agent so that the original firm cost proposal submitted
            is no longer applicable, i.e., 10% or more change in value, may
            require the timely resubmission of a revised firm cost proposal.
            Otherwise, the parties will negotiate changes affecting the cost
            proposal during negotiations or as changes to the original proposal.

      d.    Submission of a Ceiling Rough-Order-of-Magnitude Cost Proposal. If
            time will not permit the submission of a firm cost proposal for the
            contemplated change, Buyer's authorized Procurement Agent may
            request Seller to submit a written "ceiling rough-order-of-magnitude
            (CROM)" amount for the contemplated change. Seller agrees that the
            CROM is the maximum adjustment to be made in the total contract
            price; i.e. target cost, estimated cost, target fee or fixed fee, as
            appropriate for the type of contract; or in the delivery schedule
            (or time of performance) by reason of the change, if Buyer
            authorizes the change. Buyer's authorized Procurement Agent may also
            solicit such agreement on CROM limitations for adjustments to any
            other provisions of the contract which may be subject to equitable
            adjustment by reason of the change. Any such written agreement shall
            be cited in the unilateral contract modification and, upon its
            issuance, shall be a binding part of the contract. In no event shall
            the definitive equitable adjustment exceed the limitations so
            established.

      e.    Seller agrees that firm cost proposals submitted pursuant to this
            clause shall remain valid for a period of 120 days after submission
            and that CROMs submitted pursuant to this clause shall remain valid
            for a period of 90 days after submission. A change proposal accepted
            in accordance with the "Changes" article of GP4 "The Boeing Company
            General Provisions (Cost Reimbursement Contract Under Government
            Prime Contract)" shall not be considered an authorization to Seller
            to exceed the estimated cost (or authorized funding allotment) in
            the contract, unless the estimated cost is increased by the
            unilateral contract modification or bilateral contract modification.

H.12  MAKE/BUY AND DIRECTED PROCUREMENTS (PRIME FLOWDOWN)

      a.    Buyer reserves the right to participate in the development of
            Seller's Make/Buy Plan and in Seller's procurement source selection
            decisions and, if considered in the FCS program's interest, as
            determined solely by Buyer, may direct placement of Seller's
            subcontracts/purchase orders under this contract. Any such decision
            by Buyer that results in an increase to Seller's cost or schedule
            for performance will entitle Seller to an Equitable Adjustment as
            defined in Section H.9 "Equitable Adjustment." While Buyer will
            generally not interfere with Seller's internal processes, Buyer
            reserves the right to disapprove any Make/Buy decision and
            procurement source selection decision under Seller's processes
            regarding systems, subsystems or components.

      b.    In the event Buyer disagrees with a source selection made by Seller
            as a result of a competitive source selection, Buyer may direct the
            subcontract award. Also, if existing technologies, systems and major
            systems already in development by, or for the Government, represent
            in Buyer's or Government's view the best approach to achieving the
            objectives of the FCS program, Buyer's authorized Procurement Agent
            may direct their use and Seller will not be required to compete the
            item, i.e., competitive source selection is not required. Any
            decision by Buyer that requires Seller to use a directed
            subcontractor that results in an increase to Seller's cost or
            schedule for performance, will entitle Seller to an Equitable
            Adjustment as defined in Section H.9 "Equitable Adjustment."

H.13  ONE TEAM SHARED DESTINY

      a.    An essential feature of the FCS Program is the Army, DARPA, Industry
            "One Team" structure that emphasizes collaboration, partnership,
            teamwork and technical results in order to provide the Army with the
            desired capabilities to conduct full spectrum operations in the 21st
            century. In the spirit of this One Team approach, Seller agrees to
            the following:

            1.    Work cooperatively as a member of the "One Team" to identify
                  and resolve problems and facilitate contract performance.

            2.    Support the "One Team" idea of looking beyond the strict
                  bounds of the contract to formulate "One Team" actions that
                  promote a "shared destiny" of common goals and objectives.

            3.    Support and promote a relationship that is based upon open and
                  continuous communication, mutual trust and respect; to replace
                  the "us vs. them" mentality of the past with a "win-win"
                  philosophy for the future.

            4.    Support a One Team Council approach by implementing the
                  following:

                  i.    Attend and actively participate in One Team Council
                        meetings and support the Team's initiatives as required.
                        The One Team Council participants shall consist of
                        senior and executive management representatives from the
                        Army, DARPA, Boeing, SAIC and selected major/critical
                        FCS subcontractors.

H.14  FIREWALL - COMPETITION SENSITIVE INFORMATION

      a.    General. Buyer has adopted a policy of controlling access to data

      b.    Definitions

            (1)   "Competition Sensitive FCS Information" (referred to as "CSI")
                  means information that Buyer or a Subcontractor IPT Leader has
                  determined would give a bidder in a Competitive Procurement a
                  significant unfair advantage over other bidders in that
                  Competitive Procurement, which Buyer or a Subcontractor IPT
                  Leader has marked, or caused to be marked, with a label
                  containing the phrase "Competition Sensitive FCS Information."

            (2)   "Competitive Procurement" means a procurement for the FCS
                  Program that Buyer or a Subcontractor IPT Leader intends to
                  conduct in the future, in which requests for procurement will
                  be issued to more than one potential supplier.

            (3)   "CSI Firewalled Employees" means individuals who are assigned
                  to perform work on this contract and who are allowed access to

                An Employee-Owned Company   PURCHASE CONTRACT NUMBER: 4400078647

            (3)   CSI can be shared and discussed only among persons who are CSI
                  Firewalled Employees for that IPT.

            (4)   Seller will advise Buyer as to which of Seller's employees and
                  those of its subcontractors should be designated as CSI
                  Firewalled Employees for each IPT on which Seller
                  participates.

            (5)   Seller will require its employees to refrain from sharing the
                  CSI with any person who is not a CSI Firewalled Employee for
                  that IPT.

            (6)   Each IPT will have a person assigned to it who is designated
                  as the IPT Firewall Focal (if Seller is a Subcontractor IPT
                  Leader, it will, if authorized by Buyer, appoint the IPT
                  Firewall Focal). The IPT Firewall Focal on each IPT will (a)
                  maintain the list of CSI Firewalled Employees within that IPT,
                  (b) determine which documents or information created by the
                  IPT should be designated as CSI, and assure that such
                  information is properly marked and controlled, (c) determine
                  when information previously designated as CSI should cease
                  being so treated, and (d) monitor compliance by IPT
                  participants with the requirements of this clause.

            (7)   Seller will require its employees to comply with direction of
                  the IPT Firewall Focal.

            (8)   Seller will, subject to the overriding requirements of this
                  clause, treat any CSI it receives as Proprietary Information
                  and Materials under article 24 of contract Clause GP-4 in
                  contract Section I hereunder.

      d.    Participation in Competitive Procurements. Seller will not use
            existing CSI in any Competitive Procurement. Seller will restrict
            its CSI Firewalled Employees from participating in preparation of
            any proposals to Buyer or to a Subcontractor IPT Leader (either
            directly or as a team member with another company) for a Competitive
            Procurement while such persons are CSI Firewalled Employees and for
            a period of one year from the time that Seller notifies Buyer that
            such person should be removed from the list of CSI Firewalled
            Employees. Buyer will waive this restriction upon application by
            Seller if Buyer determines that the categories of CSI to which
            Seller's CSI Firewall Employees had access is not germane to a
            particular Competitive Procurement or if the only applicable CSI has
            expired (no longer considered CSI).

      e.    Administration of Firewall

            (1)   Seller will establish a firewall procedure to assure that the
                  requirements of this clause will be met. Seller will provide
                  Buyer with a copy of this procedure upon request. Buyer's
                  approval of the firewall procedure is required if Seller is a
                  Subcontractor IPT Leader.

            (2)   Seller will maintain a list of its CSI Firewalled Employees.
                  Seller will record on this list the date that the employee
                  started work on the contract and the date that the employee
                  ceased performing contract work. Seller will make this record
                  available to Buyer on request.

            (3)   Seller will train its CSI Firewalled Employees on the
                  requirements of this clause, and will maintain records of the
                  date on which each employee was trained. Seller will make
                  these records available to Buyer on request.

            (4)   Seller will require its CSI Firewalled Employees to sign a
                  form substantially similar to the following form:

                  I acknowledge that I have been informed by my employer that:

                        (i) I am obligated to maintain information designated as
                        "Competition Sensitive FCS Information" as confidential
                        and only use such for carrying out my employer's FCS
                        Program purchase contracts.

                        (ii) I may not share Competition Sensitive FCS
                        Information with any person who has not signed a similar
                        acknowledgment form. I must maintain Competition
                        Sensitive FCS Information only on the restricted
                        computer server identified by Boeing, except that I may
                        download a document containing such information to my
                        hard drive temporarily when I am working on the
                        document, and I may maintain such documents in hard copy
                        if they are kept or brought in a room to which only
                        other CSI Firewalled Employees for my IPT have access.

                        (iii) I may not work on or support proposals by my
                        employer (or any other company) for FCS Program
                        subcontracts until I am informed by my employer that
                        such restriction has been ended.

                        (iv) My failure to comply with these rules could result
                        in disciplinary action up to and including suspension or
                        termination of my employment.

                  I understand these restrictions are imposed for the purpose of
                  assuring fair and equal subcontract competitions under the FCS
                  Program.

      f.    In the event that Seller becomes aware that any of its employees or
            those of its subcontractors have violated the conditions set forth
            in this clause, Seller agrees to notify Buyer of the violation
            within 72 hours after it is discovered and the proposed remedial
            actions.

      g.    Seller will flow this clause down to any of its subcontractors who
            will have a requirement to be given access to CSI.

H.15  FIREWALL - PROPOSAL EVALUATION - SUBCONTRACTOR IPT LEADER

      a.    General. Buyer has adopted a policy that employees of Buyer and
            Subcontractor IPT Leaders who conduct Competitive Procurements and
            will participate in review of proposals therefore must meet certain
            requirements in order to assure fairness in such reviews. Seller
            agrees to further this policy by complying with the provisions of
            this clause.

      b.    Definitions

            (1)   "Proposal Information" means information that Buyer has
                  received from bidders in a Competitive Procurement.

            (2)   "Competitive Procurement" means a procurement for the FCS
                  Program that Buyer or a Subcontractor IPT Leader intends to
                  conduct in the future, in which requests for procurement will
                  be issued to more than one potential supplier.

            (3)   "Evaluator" means employees of Seller who are assigned to
                  perform evaluation work for Competitive Procurements.

            (4)   "Proposal Evaluation" means any form of participation in

                An Employee-Owned Company   PURCHASE CONTRACT NUMBER: 4400078647

      c.    Restrictions on Evaluators. Seller agrees not to designate as an
            Evaluator any person who worked for organization within Seller that
            has prepared or is submitting a bid in a Competitive Procurement
            within the year preceding the commencement of the Proposal
            Evaluation of that Competitive Procurement. Seller will prevent its
            Evaluators from participating in preparation of any proposals for a
            Competitive Procurement relative to any IPT for which they were an
            Evaluator or had access to Proposal Information until one year after
            the Evaluator has ceased performance of Proposal Evaluation work, or
            had access to Proposal Information, whichever is longer, relative to
            said IPT.

      d.    Confidentiality of Procurement Information. Seller agrees to treat
            all Proposal Information as Proprietary Information in accordance
            with a standard proprietary information agreement with bidders
            (Buyer will provide as a model, which should be followed as closely
            as possible, the agreement it used with bidders for the SDD phase
            subcontracts). Seller agrees to require its Evaluators not to share
            any Competitive Proposal Information with any employee of Seller who
            is not an Evaluator.

      e.    Administration of Firewall

            (1)   Seller will establish a firewall procedure to assure that the
                  requirements of this clause will be met. Seller will provide
                  Buyer with a copy of this procedure for approval of Buyer upon
                  Buyer's request.

            (2)   Seller will train its Evaluators on the requirements of this
                  clause, and will maintain records of the date on which each
                  employee was trained. Seller will make these records available
                  to Buyer on request.

            (3)   Seller will maintain a list of its Evaluators. Seller will
                  record on this list the date that the employee started
                  evaluation work and the date that the employee ceased
                  performing evaluation work relative to each IPT and
                  Competitive Procurement. Seller will make this list available
                  to Buyer on request.

            (4)   Seller will require its Evaluators to sign a form
                  substantially similar to the following form:

                  (a)   I will assist Boeing and my employer in the evaluation
                        of proposals submitted by various companies for the
                        purpose of obtaining subcontracts to perform work on the
                        FCS Program.

                  (b)   Information in the proposals is confidential, may only
                        be used for evaluation of the proposals, and that I may
                        not share information related to these (or any other
                        proposals) with any person who has not signed a similar
                        acknowledgment form.

                  (c)   I may not work on proposals by my employer (or any other
                        company), for competitive FCS subcontracts for one year
                        following completion of the Proposal Evaluation for each
                        IPT I was an Evaluator (or for which I had access to
                        Competitive Proposal Information), unless I am informed
                        by my employer that such restriction has been ended
                        sooner.

                  (d)   My failure to comply with these rules could result in
                        disciplinary action up to and including suspension or
                        termination of my employment.

      f.    In the event that Seller becomes aware that any of its employees or
            those of its subcontractors have violated the conditions set forth
            in this clause, Seller agrees to notify Buyer of the violation
            within 72 hours after it is discovered and the proposed remedial
            actions.

      g.    Seller will flow this clause down to any of its subcontractors who
            will participate in Proposal Evaluations.

                                                                (APRIL 30, 2004)

H.16  EMPLOYMENT OF FORMER BUYER EMPLOYEES

      a.    Seller will not employ any person who is a former employee of Buyer
            to perform work under this contract or in preparation of proposals
            for future work on the FCS Program, unless that person has worked
            for Seller for at least one year prior to commencement of such work.

      b.    Buyer will waive this clause upon application by Seller if Buyer
            determines that the employment of such former Buyer employee would
            not violate any Buyer FCS Program directive.

      c.    Seller will flow this clause down to its subcontractors at all
            tiers.

H.17  AUTHORIZATION AND ADMINISTRATION OF CPFF LEVEL-OF-EFFORT (LOE) TASK ORDERS
      (CLIN 006 ONLY)

      a.    Task Order Proposal Preparation. When requested by Buyer's
            authorized Procurement Agent, Seller shall prepare and submit a task
            order proposal. The task order proposal shall contain a detailed
            technical description of the effort to be performed under the task
            order, the number of direct labor hours proposed for each direct
            labor category, and all Additional Other Direct Costs (AODCs) and
            its associated indirect costs proposed for the proposed task order.
            A "direct labor hour" is defined as a hour of labor performed (or
            estimated to be performed) by direct charge personnel and expended
            (or estimated to be expended) in accomplishing the task order. In
            preparing the task order proposal, and for purposes of establishing
            a proposed total estimated cost, FCCOM and fixed fee, Seller shall
            use the hourly rates and fee factors set forth in the attachment
            listed in Section J entitled "CPFF Task Order Rates and Supporting
            Information Requirements." Seller shall also provide to Buyer with
            each task order proposal the support information set forth in this
            attachment. Upon receipt/evaluation of the task order proposal,
            Buyer's authorized Procurement Agent may issue a bilateral task
            order to Seller for Seller's acceptance. The task order will be
            serially numbered, dated and signed by the Buyer's authorized
            Procurement Agent.

      b.    Estimated Task Order Costs/Calculations for Preparing Task Order
            Proposals. The estimated cost (fully-burdened with G&A, excluding
            FCCOM) of each task order shall be the sum of the following cost
            bases: labor cost, subcontract cost (if applicable) and ODC (if
            applicable). Seller's estimated labor cost (excluding FCCOM) shall
            be the sum of the estimated labor costs calculated for each proposed
            labor category. The estimated labor cost (excluding FCCOM) for each
            proposed labor category shall be determined by multiplying the
            estimated number of direct labor hours (in whole numbers only) by
            the respective loaded labor rate. The "loaded labor rate" is the
            hourly rate set forth in the Section J attachment entitled "CPFF
            Task Order Rates and Supporting Information Requirements." Seller's
            estimated FCCOM on Seller's labor cost shall be the sum of the
            estimated FCCOM costs calculated for each proposed labor category.
            The estimated FCCOM for each proposed labor category shall be
            determined by multiplying the estimated number of direct labor hours
            (in whole numbers) by the respective FCCOM hourly rate set forth in
            the Section J attachment entitled "CPFF Task Order Rates and
            Supporting Information Requirements." The estimated fixed fee of
            each task order shall be the sum of the fixed fees calculated for
            each proposed cost base (labor, subcontracts and ODC). The fixed fee
            calculated for each proposed cost base shall be determined by
            multiplying the estimated cost (excluding FCCOM) by the respective
            fee rate set forth in the Section J attachment entitled "CPFF Task
            Order Rates and Supporting Information Requirements."

                An Employee-Owned Company   PURCHASE CONTRACT NUMBER: 4400078647

      c.    Task Order Issuance. Each Buyer-issued task order will specify the
            following elements: (1) a description of the effort to be performed
            (Statement of Work (SOW)). The LOE task order SOW will describe the
            required work scope in general terms only; (2) a specified
            level-of-effort (LOE). The specified LOE will indicate the MINIMUM
            quantity of total direct labor hours to be expended by Seller, the
            direct labor categories to be utilized in performing the task order
            and other LOE definition, as applicable; (3) a task order period of
            performance (stated time period) specifying beginning and ending
            dates that Seller shall devote the specified LOE; (4) estimated
            costs, including AODC plus its associated indirect costs, FCCOM and
            fixed fee for the task order; the estimated cost (fully-burdened
            with G&A) will breakout total labor cost, subcontract cost (if
            applicable) and ODC (if applicable); fixed fee and FCCOM will be
            broken out by its respective cost base, (e.g., labor, subcontracts,
            ODC); (5) SDRL Item(s) or other deliverable data; (6) a statement
            that the task order is either fully-funded or incrementally-funded;
            if incrementally funded, the task order will include the allotted
            funding and estimated funding expiration date; and (7) any
            applicable Cost Account (CA) and/or Cost Charge Numbers (CCN).

      d.    Task Order Acceptance. Within ten (10) calendar days of receipt of
            the task order, Seller shall submit a written notice of task order
            acceptance. Seller's written notice may be in the form of an e-
            mail, fax, or other appropriate means of written correspondence.
            Each task order and amendment thereto accepted by the Seller shall
            be deemed to be incorporated into this contract by reference.
            Failure of the Seller to provide written acceptance of the task
            order to the Buyer's authorized Procurement Agent shall be
            considered Seller's non-acceptance of the task order.

      e.    Task Order Performance. Seller's acceptance of a task order
            obligates it to devote the specified level of effort for the stated
            period of time set forth by the task order subject to the provisions
            of the "Limitation of Cost" or "Limitation of Funds" clause, as
            applicable to the task order. Seller agrees to diligently perform
            the specified LOE and provide all required reports and other
            required deliverables within the stated period of performance and
            estimated cost of each task order. The Seller shall continually
            evaluate the specified LOE and recommend to the Buyer any changes
            which are beneficial in attaining the overall objectives of the task
            order. In expending the specified LOE, the Seller shall promptly
            notify the Buyer's authorized Procurement Agent, in writing, when
            there is an indication of premature exhaustion, or under-expenditure
            of specified LOE before the period of performance end-date
            (expiration date) of the task order.

      f.    Trading Hours and Costs Between Direct Labor Cost Bases. Within the
            specified LOE limitations of the task order as applicable, during
            task order performance, the Seller may trade direct labor hours
            between specified direct labor categories to better achieve the task
            order objectives provided the minimum quantity of specified LOE
            hours are furnished and the total task order CPFF is not exceeded.
            The Seller shall promptly notify the Buyer's authorized Procurement
            Agent, in writing, when there is an indication of LOE cost underrun
            as a result of utilizing a cheaper labor mix than originally
            estimated. Upon such notification from the Seller, the Buyer may
            unilaterally direct the Seller to utilize a richer labor mix
            provided the task order CPFF is not exceeded.

      g.    Under-Expended ODC, Material/Subcontract Costs. The Seller shall
            promptly notify the Buyer's authorized Procurement Agent, in
            writing, when there is an indication of under-expended (an underrun
            of) specified ODC, material and subcontract costs. Upon such
            notification from the Seller, the Buyer may unilaterally direct the
            Seller to convert under-expended ODC/subcontract/material costs to
            specified LOE costs by decreasing the specified task order
            ODC/subcontract/material costs and adding specified LOE hours/costs
            such that the net change does not increase the task order CPFF.

      h.    Specified LOE Hours Shortfall. If the Seller cannot expend the
            specified LOE (minimum quantity of direct labor hours) required by
            the authorized task order without exceeding the estimated cost
            (e.g., Seller spends a richer labor mix than originally estimated),
            it shall submit a written cost overrun proposal to the Buyer's
            authorized Procurement Agent. The Seller shall not exceed the
            estimated cost established in the authorized task order unless it
            receives written notification increasing this estimated cost from
            the Buyer's authorized Procurement Agent. Any such increase in the
            estimated cost of the task order shall be considered a cost overrun
            and the fee for authorized task order shall not be changed as a
            result thereof.

                An Employee-Owned Company   PURCHASE CONTRACT NUMBER: 4400078647

      i.    Accelerated Performance/Early Completion. In the performance of the
            task order, Seller shall control fluctuations in expended LOE to
            avoid early exhaustion of specified effort and associated estimated
            cost before the specified period of performance end-date (expiration
            date) of the task order. Seller may however, submit a written
            request for acceleration of expenditure of LOE before the expiration
            date of the task order. If such request is approved by the Buyer's
            authorized Procurement Agent, the accelerated performance resulting
            in a revised task order expiration date shall be without increase in
            fee and the revised expiration date shall be formalized by task
            order amendment. Seller shall not prematurely expend task order LOE
            before the task order expiration date or incur task order expenses
            after the specified, period of performance end-date (expiration
            date) of the task order unless authorized in writing by the Buyer's
            authorized Procurement Agent.

      j.    Recording of Each Task Order in Sections B and J. All definitive
            task order values (latest amended values only) shall be recorded in
            the table set forth in Section B for the CPFF task order CLIN. This
            "task order value" is the task order estimated cost, FCCOM and CPFF.
            In addition, each definitive task order number, task order amendment
            number and corresponding effectively date of the task order shall be
            listed in contract Section J.

      k.    Task Order Funding. No task order shall be issued under this clause
            until sufficient funds are allotted to cover the work. Incremental
            funding of task order(s) shall be governed by provisions of the
            "Limitation of Funds" clause. The Limitation of Cost Clause (or
            Limitation of Funds Clause if the task order is incrementally
            funded) shall apply to each task order and not the accumulative
            costs (or funding) of each task order issued under this clause.

      l.    Final Technical Report. Seller agrees to set aside a sufficient
            amount of funds from each task order to prepare and submit to Buyer
            a comprehensive final technical report (minimum of 500 words) at the
            end of the task order period of performance. If the Seller fails to
            set aside these funds and expends all the estimated costs provided
            by the task order before delivering the final technical report, the
            Seller agrees to provide this report at no additional cost to Buyer.
            If no final report is specified for a given task order, then this
            requirement is self-deleting for that task order.

      m.    No Obligation to Issue Task Order. Buyer is not obligated to issue
            any task orders under this clause. The number and total dollar value
            of each task order issued under this clause is unlimited provided
            the SOW for each task order is within the general work scope of the
            "Task Order" clause defined in Section C.

      n.    Contract/Task Order Period-of-Performance. In no event shall the
            period of performance of any task order extend beyond the overall
            period of performance of the CPFF task order CLIN specified in
            Section F.

      o.    Unilateral Task Order Changes. Buyer is authorized to unilaterally
            change the SOW, period of performance or specified LOE of any
            authorized task order. As a result of issuing any such unilateral
            change by the Buyer's authorized Procurement Agent, the task order
            shall be subject to equitable adjustment pursuant to the provisions
            of the Change Order Clause. Any such equitable adjustment in task
            order CPFF shall utilize the fee rate(s) set forth in the Section J
            attachment entitled "CPFF Task Order Rates and Supporting
            Information Requirements."

      p.    Task Order Payment. Buyer shall pay Seller its reimbursable costs
            pursuant to the "Allowable Cost and Payment" clause, and the task
            order fixed fee in accordance with the Section H clause entitled
            "CPFF Task Order Acceptance - Certification of Utilization of
            Hours," and the Section H clause entitled "Payment of Fixed Fee -
            CPFF Task Orders (LOE)."

      q.    Financial Reporting. Seller shall report cost account data to Buyer
            for each task order in accordance with the financial reporting
            requirements specified elsewhere in this contract.

            authorized Procurement Agent, Seller shall prepare and submit a task
            order proposal. The task order proposal shall contain a detailed
            technical description of the effort to be performed under the task
            order, the number of direct labor hours proposed for each direct
            labor category, and all Additional Other Direct Costs (AODCs) and
            its associated indirect costs proposed for the proposed task order.
            A "direct labor hour" is defined as a hour of labor performed (or
            estimated to be performed) by direct charge personnel and expended
            (or estimated to be expended) in accomplishing the task order. In
            preparing the task order proposal, and for purposes of establishing
            a proposed total estimated cost, FCCOM and fixed fee, Seller shall
            use the hourly rates and fee factors set forth in the attachment
            listed in Section J entitled "CPFF Task Order Rates and Supporting
            Information Requirements." Seller shall also provide to Buyer with
            each task order proposal the support information set forth in this
            attachment. Upon receipt/evaluation of the task order proposal,
            Buyer's authorized Procurement Agent may issue a bilateral task
            order to Seller for Seller's acceptance. The task order will be
            serially numbered, dated and signed by the Buyer's authorized
            Procurement Agent.

      b.    Estimated Task Order Costs/Calculations for Preparing Task Order
            Proposals. The estimated cost (fully-burdened with G&A, excluding
            FCCOM) of each task order shall be the sum of the following cost
            bases: labor cost, subcontract cost (if applicable) and ODC (if
            applicable). Seller's estimated labor cost (excluding FCCOM) shall
            be the sum of the estimated labor costs calculated for each proposed
            labor category. The estimated labor cost (excluding FCCOM) for each
            proposed labor category shall be determined by multiplying the
            estimated number of direct labor hours (in whole numbers only) by
            the respective loaded labor rate. The "loaded labor rate" is the
            hourly rate set forth in the Section J attachment entitled "CPFF
            Task Order Rates and Supporting Information Requirements." Seller's
            estimated FCCOM on Seller's labor cost shall be the sum of the
            estimated FCCOM costs calculated for each proposed labor category.
            The estimated FCCOM for each proposed labor category shall be
            determined by multiplying the estimated number of direct labor hours
            (in whole numbers) by the respective FCCOM hourly rate set forth in
            the Section J attachment entitled "CPFF Task Order Rates and
            Supporting Information Requirements." The estimated fixed fee of
            each task order shall be the sum of the fixed fees calculated for
            each proposed cost base (labor, subcontracts and ODC). The fixed fee
            calculated for each proposed cost base shall be determined by
            multiplying the estimated cost (excluding FCCOM) by the respective
            fee rate set forth in the Section J attachment entitled "CPFF Task
            Order Rates and Supporting Information Requirements."

      c.    Task Order Issuance. Each Buyer-issued task order will specify the
            following elements: (1) a description of the effort to be performed
            (Statement of Work (SOW)). The Completion-type task order SOW will
            describe the required work scope by stating a definite goal or
            target and by specifying an end-product; (2) a milestone schedule
            and/or delivery schedule; (3) a task order period of performance
            (stated time period) specifying beginning and ending dates that
            Seller shall perform and complete the task order; (4) estimated
            costs, including AODC plus its associated indirect costs, FCCOM and
            fixed fee for the task order; the estimated cost (fully-burdened
            with G&A) will breakout total labor cost, subcontract cost (if
            applicable) and ODC (if applicable); fixed fee and FCCOM will be
            broken out by its respective cost base, (e.g., labor, subcontracts,
            ODC); (5) SDRL Item(s), if applicable; (6) a statement that the task
            order is either fully-funded or incrementally-funded; if
            incrementally funded, the task order will include the allotted
            funding and estimated funding expiration date; and (7) any
            applicable Cost Account (CA) and/or Cost Charge Numbers (CCN).

      d.    Task Order Acceptance. Within ten (10) calendar days of receipt of
            the task order, Seller shall submit a written notice of task order
            acceptance. Seller's written notice may be in the form of an e-mail,
            fax, or other appropriate means of written correspondence. Each task
            order and amendment thereto accepted by the Seller shall be deemed
            to be incorporated into this contract by reference. Failure of the
            Seller to provide written acceptance of the task order to the
            Buyer's authorized Procurement Agent shall be considered Seller's
            non-acceptance of the task order.

      e.    Task Order Performance. Seller's acceptance of a task order
            obligates it to complete all the effort set forth by the task order
            subject to the provisions of the "Limitation of Cost" or "Limitation
            of Funds" clause, as applicable to the task order.

      f.    Under-Expended ODC, Material/Subcontract Costs. The Seller shall
            promptly notify the Buyer's authorized Procurement Agent, in
            writing, when there is an indication of under-expended (an underrun
            of) specified ODC, material and subcontract costs. Upon such
            notification from the Seller, the Buyer may unilaterally direct the
            Seller to convert under-expended ODC/subcontract/material costs to
            additional work tasks by decreasing the specified task order
            ODC/subcontract/material costs and adding work tasks and associated
            additional costs such that the net change does not increase the task
            order CPFF.

      g.    Unable to Complete Work. If the Seller cannot complete the definite
            work goals, targets and/or deliverables required by the authorized
            task order without exceeding the estimated cost, it shall submit a
            written cost overrun proposal to the Buyer's authorized Procurement
            Agent that successfully completes the task order. The Seller shall
            not exceed the estimated cost established in the authorized task
            order unless it receives written notification increasing this
            estimated cost from the Buyer's authorized Procurement Agent. Any
            such increase in the estimated cost of the task order shall be
            considered a cost overrun and the fee for authorized task order
            shall not be changed as a result thereof.

      h.    Accelerated Performance/Early Completion. In the performance of the
            task order, Seller shall coordinate with Buyer any accelerated
            performance or early deliveries.

      i.    Recording of Each Task Order in Sections B and J. All definitive
            task order values (latest amended values only) shall be recorded in
            the table set forth in Section B for the CPFF task order CLIN. This
            "task order value" is the task order estimated cost, FCCOM and CPFF.
            In addition, each definitive task order number, task order amendment
            number and corresponding effectively date of the task order shall be
            listed in contract Section J.

      j.    Task Order Funding. No task order shall be issued under this clause
            until sufficient funds are allotted to cover the work. Incremental
            funding of task order(s) shall be governed by provisions of the
            "Limitation of Funds" clause. The Limitation of Cost Clause (or
            Limitation of Funds Clause if the task order is incrementally
            funded) shall apply to each task order and not the accumulative
            costs (or funding) of each task order issued under this clause.

      k.    No Obligation to Issue Task Order. Buyer is not obligated to issue
            any task orders under this clause. The number and total dollar value
            of each task order issued under this clause is unlimited provided

            period of performance of the CPFF task order CLIN specified in
            Section F.

            change the SOW including goals/targets, period of performance, or
            delivery/performance schedule of any authorized task order. As a
            result of issuing any such unilateral change by the Buyer's
            authorized Procurement Agent, the task order shall be subject to
            equitable adjustment pursuant to the provisions of the Change Order
            Clause. Any such equitable adjustment in task order CPFF shall
            utilize the fee rate(s) set forth in the Section J attachment

            requirements specified elsewhere in this contract.

H.20  CPFF TASK ORDER ACCEPTANCE - CERTIFICATION OF COMPLETION (CLIN 0006 ONLY)

                  IS A PAYMENT IN ADDITION TO REGULAR SALARIES AND WAGES BY
                  CONTRACTORS TO WORKERS WHOSE EMPLOYMENT IS BEING INVOLUNTARILY
                  TERMINATED. PAYMENTS FOR EARLY RETIREMENT INCENTIVE PLANS ARE
                  NOT COVERED IN THIS CLAUSE.

            (B)   SEVERANCE PAY TO BE ALLOWABLE MUST MEET THE GENERAL
                  ALLOWABILITY CRITERIA IN PARAGRAPH (i) OF THIS SUBSECTION,
                  AND, DEPENDING UPON WHETHER THE SEVERANCE IS NORMAL OR
                  ABNORMAL, CRITERIA IN PARAGRAPH (ii) FOR NORMAL SEVERANCE PAY
                  OR PARAGRAPH (iii) FOR ABNORMAL SEVERANCE PAY ALSO APPLY. IN
                  ADDITION, PARAGRAPH (ii) OF THIS SUBSECTION APPLIES IF THE
                  SEVERANCE COST IS FOR FOREIGN NATIONALS EMPLOYED OUTSIDE THE

[SAIC (R) LOGO] SCIENCE APPLICATIONS
                INTERNATIONAL CORPORATION
                An Employee-Owned Company       PAGE 44 A OF 48, REV. B (SA-006)
                                                                (MARCH 31, 2005)

                  (iii) Abnormal or mass severance pay is of such a conjectural
                        nature that measurement of costs by means of an accrual
                        will not achieve equity to Buyer and Seller. Thus,
                        accruals for this purpose are not allowable. However,
                        Buyer recognizes its obligation to participate, to the
                        extent of its fair share, in any specific payment. Thus,
                        allowability will be considered on a case-by-case basis.

            (2)   "Reasonable costs continuing after termination" - Despite all
                  reasonable efforts by Seller, costs that cannot be
                  discontinued immediately after the effective date of
                  termination are generally allowable. However, any costs
                  continuing after the effective date of the termination due to
                  the negligent or willful failure of Seller to discontinue the
                  costs shall be unallowable.

            (3)   "Settlement of expenses" - Settlement expenses, including the
                  following, are generally allowable:

                  (A)   Accounting, legal, clerical, and similar costs
                        reasonably necessary for

                        (i)   The preparation and presentation, including
                              supporting data, of settlement claims to Buyer;
                              and

                        (ii)  The termination and settlement of subcontracts

                  (B)   Reasonable costs for the storage, transportation,
                        protection, and disposition of property acquired or
                        produced for this contract.

                  (C)   Indirect costs related to salary and wages incurred as
                        settlement expenses in paragraphs (A) and (B); normally,

                  24. CONFIDENTAL, PROPRIETARY, AND TRADE SECRET INFORMATION AND
                  ITEMS. Buyer and Seller shall each keep confidential and
                  protect from unauthorized use and disclosure all (a)
                  confidential, proprietary and/or trade secret information; (b)
                  tangible items and software containing, conveying or embodying
                  such information; and (c) tooling identified as being subject
                  to this article and obtained, directly or indirectly, from the
                  other in connection with this contract or other agreement
                  referencing this contract (collectively referred to as a
                  "Proprietary Information and Materials"). Buyer and Seller
                  shall each use Proprietary Information and Materials of the
                  other only in the performance of and for the purpose of this
                  contract and/or any other agreement referencing this contract.
                  However, despite any other obligations or restrictions imposed
                  by this article, Buyer shall have the right to use, disclose
                  and reproduce Seller's Proprietary Information and Materials,
                  and make derivative works thereof, for the purposes of
                  testing, certification, use, sale or support of any goods
                  delivered under this contract or any other agreement
                  referencing this contract. Any such use, disclosure,
                  reproduction or derivative work by Buyer shall, whenever
                  appropriate, include a restrictive legend suitable to the
                  particular circumstances. The restrictions on disclosure or
                  use of Proprietary Information and Materials by Seller shall
                  apply to all materials derived by Seller or others from
                  Proprietary Information and Materials provided by Buyer. Upon
                  Buyer's request at any time, and in any event upon the
                  completion, termination or cancellation of this contract,
                  Seller shall return to Buyer all of Buyer's Proprietary
                  Information and Materials and all materials derived there
                  from, unless specifically directed otherwise in writing by
                  Buyer. Seller shall not, without the prior written
                  authorization of Buyer, sell or otherwise dispose of (as scrap
                  or otherwise) any parts or other materials containing,
                  conveying, embodying or made in accordance with or by
                  reference to any Proprietary Information and Materials of
                  Buyer. Prior to disposing of such parts or other materials as
                  scrap, Seller shall render them unusable. Buyer shall have the
                  right to audit Seller's compliance with this article. Seller
                  may disclose Proprietary Information and Materials of Buyer to
                  its subcontractors as required for the performance of this
                  contract, provided that each such subcontractor first agrees
                  in writing to the same obligations imposed upon Seller under
                  this article relating to Proprietary Information and
                  Materials. Seller shall be liable to Buyer for any breach of
                  such obligation by such subcontractor. The provisions of this
                  article are effective in lieu of any restrictive legends or
                  notices applied to Proprietary Information and Materials. The
                  provisions of this article shall survive the performance,
                  completion, termination or cancellation of this contract.

SEA B-23 - EXPEDITING CONTRACT CLOSEOUT (NAVSEA) (DEC 1995)

(a) As part of the negotiated fixed price or total estimated amount of this
contract, both the Government and the Contractor have agreed to waive any
entitlement that otherwise might accrue to either party in any residual dollar
amount of $500 or less at the time of final contract closeout. The term
"residual dollar amount" shall include all money that would otherwise be owed to
either party at the end of the contract, except that, amounts connected in any
way with taxation, allegations of fraud and/or antitrust violations shall be
excluded. For purposes of determining residual dollar amounts, offsets of money
owed by one party against money that would otherwise be paid by that party may
be considered to the extent permitted by law.

(b) This agreement to waive entitlement to residual dollar amounts has been
considered by both parties. It is agreed that the administrative costs for
either party associated with collecting such small dollar amounts could exceed
the amount to be recovered.

                        MAN TRANSPORTABLE ROBOTIC SYSTEM

1.0   SCOPE

      This statement of work (SOW) describes the contractor's tasks required for
the modified commercial item acquisition and support of a Man Transportable
Robotic System (MTRS).

1.1   BACKGROUND

      The MTRS will provide the military Explosive Ordnance Disposal (EOD)
technician with a man transportable capability to remotely perform
reconnaissance during extremely hazardous EOD missions involving unexploded
ordnance (UXO) and improvised explosive devices (IEDs). The MTRS will be able to
operate in both urban and rural environments. The MTRS will be a modular system
that will allow interoperability with future mission packages such as chemical
and nuclear detectors, EOD render safe tools, EOD disruption tools, and EOD
disposal tools. The system architecture (hardware and software) of the MTRS will
be inherently expandable and inherently upgradeable to allow for future
enhancements.

2.0   REQUIREMENTS

2.1   GENERAL

      The contractor shall deliver two MTRS performance specification
verification models (PSVM 1 and PSVM 2) to the Government that are in compliance
with the performance specification (Appendix A). The compliance of the PSVMs
with the performance specification will be verified through testing and analysis
that will be performed by the Government. The performance specification
constitutes the system functional/performance baseline for the MTRS. The
performance specification may be updated, as necessary, based on the results of
the Government's testing and analysis of the PSVMs. The Government may purchase
two production representative models (PRM 1 and PRM 2) that conform to the
updated performance specification. Any changes to the MTRS due to the updating
of the performance specification shall be subject to the changes clause of the
contract. The PRMs will undergo final testing to be performed by the Government
prior to a Production Approval decision. Following a successful Production
Approval decision, the Government may purchase up to 250 production units,
initial spares, and post-production support.

2.2   PERFORMANCE SPECIFICATION VERIFICATION MODELS PHASE

2.2.1 PERFORMANCE SPECIFICATION VERIFICATION MODELS. The contractor shall
deliver two MTRS PSVMs that are in compliance with the performance
specification.

SEA C-19 - CONFIGURATION MANAGEMENT (NAVSEA) (JUN 1999)

(a) Baseline Definition - For configuration control purposes, all contractual
documentation in effect at the time of contract award shall constitute the
Contract Baseline which shall be considered incorporated in the baseline
documentation.

(b) General Requirement - (1) The Contractor shall maintain a Configuration
Control Program to assure that all detail level work being performed under this
contract is in compliance with appropriate baseline documentation. The
Contractor shall prepare a Configuration Management Plan for approval by the
Government.

      (2) Whenever a situation arises wherein the Contractor cannot comply with
a baseline document, or whenever intent of such documentation is significantly
changed by detail level documentation, the Contractor shall submit change
documents to modify baseline documents to resolve the conflict or to allow
non-compliance. Whenever the cost of implementing a proposed change is less than
$500,000, the Contractor shall provide documentation explaining the nature of
related costs as shown on the change document. Whenever the contract cost
changes by more than $500,000, the Contractor shall complete such cost and
pricing data as the Contracting Officer shall require detailing all related
costs, and attach it to the change document. Change documentation shall be
submitted to the Supervisor in accordance with the Contract Data Requirements
List (CDRL), and as described in paragraphs (c) through (f) below.

Engineering Change Proposals (Short Form, DP Form 1693) - MIL-STD-973 shall be
used as general guidance for completing this standard form. This form shall be
used whenever the detail level physical configuration, material quality,
operational or functional performance of equipment or installed systems will not
be in compliance with baseline design-related documents (Ship Specifications,
Contract Drawings, etc.), and a change to the baseline document is considered an
appropriate means of resolving a design-related issue. Documentation shall be
developed in sufficient detail to enable Government review and evaluation of the
merits of the proposed change, including cost and scheduling impact, ship class
impact, and consequences if disapproved. Due to space limitations of the
Standard DD Form 1693, the Contractor may use form continuation sheets to assure
that sufficient detailed information, including appropriate illustrations, is
provided. All existing drawings and technical manuals impacted by the change
shall be listed along with a brief narrative explanation of needed changes to
incorporate the Engineering Change Proposal (ECP) if approved. Weight and moment
data incidental to the change shall be provided in Block 15 of the form. The
Contractor shall also prepare applicable baseline document insert sheets, with
specific word changes or proposed re-write, to facilitate baseline documentation
changes.

(d) Non-Engineering Change Proposals (NAVSEA Form 4130) - This form shall be
used to document administrative, procedural, scheduling, or documentation
changes that do not directly impact the physical configuration of the ship. The
completed Form 4130 should explain the nature of the problem, identify the
applicable baseline document (i.e., Contract Data Requirement List (CDRL),
Contract Clause, etc.) and provide a detailed explanation justifying the
proposed course of action desired to resolve the problem. Due to the space
limitation on the form, continuation sheets may be used. Insert sheets for
applicable documents shall also be attached to facilitate change action in the
event the Non-Engineering Change Proposal (NECP) is approved.

(e) Deviations and Waivers (DD Form 1694) - In the event that a baseline
design-related document requirement cannot be met, and a change to the baseline
document is considered inappropriate, the Contractor shall submit a request for
deviation or waiver, as applicable. The explanation of "need for deviation" of
Block 24 should provide detailed justification and consequences of approval, to
include technical details explaining the degree of non-compliance or effect on
ship equipment or system operation constraints. In a similar manner, a waiver
shall

document an "as built" configuration that departs from baseline documentation,
and should include any proposed corrections or modifications to better meet the
intent of the baseline document. MIL-STD-973 provides guidance in completing DD
Form 1694.

(f) Equitable Adjustments for Change Documentation Preparations - For its effort
expended in preparing ECPs, NECPs, Deviations and Waivers, the Contractor shall
receive equitable adjustment under the following circumstances.

      (1) In the event the Contractor, on its own initiative, and without
written request from the Government, develops a change document that is later
disapproved by the Government, the Contractor shall bear the cost of this
effort.

      (2) To avoid such loss, and at its option, the Contractor may submit a
"preliminary" document that outlines intent, but without detailed supporting
documentation and request the Supervisor's approval for expenditure of effort to
complete the detailed supporting documentation. In the event the Supervisor
denies this request, the Contractor will bear the cost of development of the
"preliminary" document, and shall make no further effort to complete detailed
supporting documentation.

      (3) In the event the Supervisor approves the Contractor's request to
develop supporting documentation, the Contractor shall be equitably compensated
for its effort for both the "preliminary" and "final" documentation, regardless
of whether or not the change document is later approved.

      (4) In the event the Government requests in writing that the Contractor
develop change documentation, the effort expended by the Contractor in
developing such documentation shall be subject to equitable adjustment,
regardless of whether or not the change document is later approved.

      (5) In the event the Contractor, on its own initiative, and without
written request from the Government, develops a change document that is later
approved by the Government, the cost of developing such documentation shall be
incorporated in the contract modification that implements the change.

      (6) Failure to agree to such equitable adjustment in contract price shall
constitute a dispute, and shall be adjudicated in accordance with the
requirements of the clause entitled "DISPUTES" (FAR 52.233-1).

(g) The Contractor shall verify (by physical inspection of the vessel) to the
Government, that all Field Modification Requests (FMRs) and Headquarters
Modification Requests (HMRs) (including Government responsible trial items) have
been incorporated into the vessel. Verification shall include:

      (1) List of all HMRs and FMRs authorized to date.

      (2) List of those HMRs and FMRs verified to be complete.

      (3) List of those HMRs and FMRs which are partially complete or not
started with scheduled date for their completion.

(h) Any cost reduction proposal submitted pursuant to the clause entitled "VALUE
ENGINEERING" (FAR 52.248-1) shall be submitted as a Code V Engineering Change
Proposal (VECP) on the DD Form 1693 series and shall be supplemented by the
information required by the "VALUE ENGINEERING" clause.

      The Government will evaluate equally, as regards time of delivery, offers
      that propose delivery of each quantity within the applicable delivery
      period specified above. Offers that propose delivery that will not clearly
      fall within the applicable required delivery period specified above, will
      be considered nonresponsive and rejected. The Government reserves the
      right to award under either the required delivery schedule or the proposed
      delivery schedule, when an offeror offers an earlier delivery schedule
      than require above. If the offeror proposes no other delivery schedule,
      the require delivery schedule above will apply.

(b) Attention is directed to the Contract Award provision of the solicitation
that provides that a written award or acceptance of offer mailed, or otherwise
furnished to the successful offeror, results in a binding contract. The
Government will mail or otherwise furnish to the offeror an award or notice of
award not later than the day award is dated. Therefore, the offeror should
compute the time available for performance beginning with the actual date of
award, rather than the date the written notice of award is received from the
Contracting Officer through the ordinary mails. However, the Government will
evaluate an offer that proposes delivery based on the Contractor's date of
receipt of the contract or notice of award by adding (1) five calendar days for
delivery of the award through the ordinary mails, or (2) one working day if the
solicitation states that the contract or notice of award will be transmitted
electronically. (The term "working day" excludes weekends and U.S. Federal
holidays.) If, as so computed, the offered delivery date is later than the
required delivery date, the offer will be considered nonresponsive and rejected.

Government from using the report.

(c) The contractor may request a meeting to discuss the CPAR. The meeting is to
be requested via e-mail to the CPARS Program Manager no later than seven days
following receipt of the CPAR. A meeting will then be held during the

(d) Undefinitized Orders. Whenever the Contracting Officer determines that
urgent demands or requirements prevent the issuance of a firm priced order, the
Contracting Officer may issue an unpriced order. Such order may be unilateral or
bilateral and shall establish a limitation on Government liability, a maximum
ceiling amount and a schedule for definitization, as described in subparagraph
(f)(2) below. Upon request, the Contractor shall submit a maximum ceiling amount
proposal before the undefinitized order is issued. The maximum ceiling amount is
the maximum price at which the order may be definitized. Except as provided in
paragraph (e) below, the Contractor shall commence performance of the order upon
receipt. The clause entitled "CONTRACT DEFINITIZATION" (DFARS 252.217-7027)
shall be included in any undefinitized order.

(e) Rejection of Unilateral Orders. The Contractor may reject any unilateral
order if the Contractor determines it cannot feasibly perform the order, or if
it does not concur with the maximum ceiling amount. However, each unilateral
order shall be deemed to have been accepted by the Contractor unless within
fifteen (15) days of issuance of the order the Contractor notifies the
Contracting Officer in writing of its rejection of the order.

(f) Definitization of Undefinitized Orders. (1) The Contractor agrees that
following the issuance of an undefinitized order, it will promptly begin
negotiating with the Contracting Officer the price and terms of a definitive
order that will include: (A) all clauses required by regulation on the date of
the order; (B) all clauses required by law on the date of execution of the
definitive order; and, (C) other mutually agreeable clauses, terms and/or
conditions. No later than sixty (60) days after the undefinitized order is
issued, the Contractor shall submit a cost proposal with sufficient data to
support the accuracy and derivation of its price; and, when required by FAR or
the Contracting Officer, cost or pricing data. If additional cost information is
available prior to the conclusion of negotiations, the Contractor shall provide
that information to the Contracting Officer. The price agreed upon shall be set
forth in a bilateral modification to the order. In no event shall the price
exceed the maximum ceiling amount specified in the undefinitized order.

      (2) Each undefinitized order shall contain a schedule for definitization
which shall include a target date for definitization and dates for submission of
a qualifying proposal, beginning of negotiations and, if appropriate, submission
of make-or-buy and subcontracting plans and cost or pricing data. Submission of
a qualifying proposal in accordance with the definitization schedule is a
material element of the order. The schedule shall provide for definitization of
the order by the earlier of:

            (i)   specified target date which is not more than 180 days after
                  the issuance of the undefinitized order. However, that target
                  date may be extended by the Contracting Officer for up to 180
                  days after the Contractor submits a qualifying proposal as
                  defined in DFARS 217.7401; or

            (ii)  the date on which the amount of funds obligated by the
                  Government under the undefinitized order exceeds fifty percent
                  (50%) of the order's maximum ceiling amount, except as
                  provided in subparagraph (f)(3) below.

      (3) If agreement on a definitive order is not reached within the time
provided pursuant to subparagraph (f)(2) above, the Contracting Officer may,
with the approval of the Head of the Contracting Activity, determine a
reasonable price in accordance with Subpart 15.8 and Part 31 of the FAR, and
issue a unilateral order subject to Contractor appeal as provided in the
"DISPUTES" clause (FAR 52.233-1). In any event, the Contractor shall proceed
with completion of the order, subject to the "LIMITATION OF GOVERNMENT
LIABILITY" clause (FAR 52.216-24).

(g) Limitation of Government Liability. (1) Each undefinitized order shall set
forth the limitation of Government liability, which shall be the maximum amount
that the Government will be obligated to pay the Contractor for performance of
the order until the order is definitized. The Contractor is not authorized to
make expenditures or incur obligations exceeding the limitation of Government
liability set forth in the order. If such expenditures are made, or if such
obligations are incurred, those expenditures and obligations will be at the
Contractor's sole risk and expense. Further, the limitation of liability shall
be the maximum Government liability if the order is terminated. The clause at
FAR 52.216-24 shall be included in any undefinitized order.

      (2) Except for undefinitized orders for Foreign Military Sales; purchases
of less than $25,000; special access programs; and Congressionally-mandated long
lead procurements; and except as otherwise provided in subparagraph (g)(3)
below, the limitation of Government liability shall not exceed fifty percent
(50%) of the maximum ceiling amount of an undefinitized order. In the case of
orders within these excepted categories, however, the procedures set forth
herein shall be followed to the maximum extent practical.

      (3) If the Contractor submits a qualifying proposal, as defined in DFARS
217.7401, to definitize an order before the Government obligated fifty percent
(50%) of the maximum ceiling amount, the Contracting Officer may increase the
limitation of Government liability up to no more than seventy-five percent (75%)
of the maximum ceiling amount or up to seventy-five percent (75%) of the price
proposed by the Contractor, whichever is less.

      (4) If at any time the Contractor believes that its expenditures under an
order will exceed the limitation of Government liability, the Contractor shall
so notify the Contracting Officer, in writing, and propose an appropriate
increase in the limitation of Government liability of such order. Within thirty
(30) days of such notice, the Contracting Officer will either (i) notify the
Contractor in writing of such appropriate increase, or (ii) instruct the
Contractor how and to what extent the work shall be continued; provided,
however, that in no event shall the Contractor be obligated to proceed with work
on an undefinitized order beyond the point where its costs incurred plus a
reasonable profit exceed the limitation of Government liability, and provided
also that in no event shall the Government be obligated to pay the Contractor
any amount in excess of the limitation of Government liability specified in any
such order prior to definitization.

(h) Initial Spares. The limitations set forth in paragraph (d) and subparagraphs
(f)(2), (g)(2) and (g)(3), do not apply to undefinitized orders for the purchase
of initial spares.

(i) Ordering Activities. The following activities are authorized to issue orders
hereunder:

The Contracting Officer of the Ordering Activity shall forward a copy of each
executed order marked "DD-350", to the Commander, Naval Sea Systems Command,
ATTN: SEA 0293.

(j) Funds in the following amount are committed under this Basic Ordering
Agreement for use by the Ordering Activity in obligating funds to pay for orders

1. Section 2.2.1.4.2 of the Performance Specification is hereby changed as
follows:

      From:

            2.2.1.4.2 CABLED MODE. When being operated in cabled mode (e.g.
            fiber optic, coaxial, multi-conductor), the maximum amount of cable
            that can be deployed between the vehicle and the OCS shall be no
            less than 200 meters. The desired maximum amount of cable is 500
            meters. An indication shall be provided to warn the operator when 20
            meters of cable or less remains to be payed out. A conspicuous
            marking of the cable that can be viewed with a vehicle camera is a
            sufficient indication. THE CABLE SHALL BE STORED ON THE VEHICLE AND
            BE CAPABLE OF PAYING OUT FREELY FROM THE VEHICLE. A self-reeling
            mechanism for cable retrieval located on the vehicle that can be
            controlled from the OCS during a mission is desired. If such a
            self-reeling mechanism is not provided on the vehicle, then a manual
            or powered reeling mechanism shall be provided at the OCS to
            facilitate the retrieval of cable during a mission. A means to
            facilitate the manual retrieval of cable onto the vehicle after a
            mission shall be provided. The capability to lower, lift, and drag
            the vehicle by the cable (without damaging the cable) is desired.

            marking of the cable that can be viewed with a vehicle camera is a
            sufficient indication. NO LESS THAN 150 METERS OF CABLE SHALL BE
            STORED ON THE VEHICLE AND BE CAPABLE OF PAYING OUT FREELY FROM THE
            VEHICLE. HAVING ALL OF THE CABLE STORED ON THE VEHICLE IS DESIRED. A
            self-reeling mechanism for cable retrieval located on the vehicle
            that can be controlled from the OCS during a mission is desired. If
            such a self-reeling mechanism is not provided on the vehicle, then a
            manual or powered reeling mechanism shall be provided at the OCS to
            facilitate the retrieval of cable during a mission. A means to

            distance of 500 meters in semi-rugged terrain as one load by two
            personnel in one trip. The entire weight of the load shall be borne
            by the two personnel. A weight of no more than 75 pounds (vice 145
            pounds) is desired. A load carrying apparatus that combines
            stretcher type handles and shoulder support is recommended, but not
            required, to facilitate transporting the load. Any load carrying
            apparatus shall be considered to be part of the system and the
            weight of such apparatus shall be included in the 145 pound weight
            limit. Any modular vehicle mobility aids shall also be included in
            the 145 pound weight limit. The load carrying apparatus, if

                  PHASE III - PRODUCTION

                  Phase III is for production. Only one contractor will be
                  funded for the Production phase. At contract award, the
                  contractor shall provide an estimated unit price. Prior to
                  entering into Phase III, the Government will issue a Request
                  for Proposal (RFP) to the contractor(s). The RFP will request
                  the contractor to provide their final production unit costs
                  based on the final system configuration agreed upon in Phase
                  II or Phase I should the Government decide not to fund Phase
                  II. The offeror who offers the lowest unit price will be
                  funded for the production phase. Phase III includes CLINs 0016
                  THROUGH 0025 and the ordering period for Phase III shall be
                  from twenty-eight (28) months after date of contract (ADC)
                  through ten (10) years ADC.
