                              PART I - THE SCHEDULE

                                    Section B

                      Supplies or Services and Prices/Cost

ARTICLE B-1 TYPE OF CONTRACT

This is a cost-plus-award-fee, term form of contract with a level of effort
basis. The Contractor is obligated to provide Engineering, Engineering Support,
and Facilities and Laboratory Support. Specific requirements will be levied on
the Contractor by Work Orders in accordance with the Statement of Work (SOW),
Attachment J-1.

ARTICLE B-2 EFFORT REQUIRED DURING CONTRACT PERFORMANCE

A.      The Contractor shall provide non-personal services for NASA as described
        in Article C-1, "Scope of Work" and Attachment J-1, "Statement of Work"
        on a level of effort (LOE) basis. In performance of the described work
        during the contract period set forth below, the Contractor shall not
        exceed the total labor hours on the contract, including subcontractor
        and overtime hours.

        Table B-2
                                                      Labor Hours

          10/1/99 - 9/30/00          375,502         387,115         398,728
          10/1/00 - 9/30/01          375,502         387,115         398,728

B.      If the Contractor has not provided the specified minimum quantity of
        total contract labor hours set forth in the above paragraph A, an
        equitable downward adjustment will be made in estimated cost and
        available award fee. The downward adjustment will be based on the
        difference between the minimum labor hours specified under this Article
        and the number of labor hours provided by the Contractor. This provision
        does not affect the Government's right to reduce the quantity of labor
        hours during the term of this contract pursuant to the Termination
        Clause (FAR 52.249-6).

C.      When the total labor hours expended reach 95% of the maximum labor hours
        specified above, the Contractor shall notify the Contracting Officer as
        to whether or not the Contractor believes that amount will be sufficient
        for the balance of the period of performance, or if additional labor
        hours will be required. In the latter case, the notification shall
        include the estimated "adequate through" date for the unexpended balance
        and an estimate of the additional hours required for the balance of the
        period of performance. If, during the term of the contract, an increase
        in the specified maximum number of labor hours becomes necessary, the
        Government may elect to increase the maximum labor hours pursuant to
        Article B-5, "Options to Extend the Period of Contract and Options for
        Incremental Increase of Effort".

D.      As used herein, the term "labor hours" shall include the productive and
        non-productive time of the employees assigned to this contract
        (including subcontracted and overtime labor hours).

Contractor may be required to provide Work Order related items identified in, or
required by, Work Orders issued in accordance with Attachment J-l, Appendix 3

ARTICLE B-5 OPTIONS TO EXTEND THE PERIOD OF CONTRACT AND
            OPTIONS FOR INCREMENTAL INCREASE OF EFFORT

 A.     Options to Extend the Period of Contract

        1.      This contract is renewable for the periods identified as options
                in Table B-3 at the option of the Government.

        2.      The Government may extend the term of the contract for the
                quantities of supplies or services and period specified in the
                Schedule by written modification of this contract before the
                current contract performance period expires, provided that the
                Government will give the Contractor a preliminary written notice
                of intent to extend at least 60 days prior to expiration of any
                current period of performance. The preliminary notice does not
                commit the Government to exercise the option.

        3.      If the Government exercises any option, the extended contract
                shall be considered to include this option provision.

NAS10-98001 (EDC)                                                      Section B
--------------------------------------------------------------------------------

        4.      The total duration of this contract, including the exercise of
                any option(s) under this clause, shall not exceed five (5)
                years.

        5.      It is understood and agreed that any continued performance of
                services from period to period shall be at the sole
                determination of the Government and will be contingent upon
                prior satisfactory performance. Failure to renew the contract
                for any subsequent period of performance shall not be considered
                as a termination for the convenience of the Government.

B.       Options for Incremental Increase of Effort

         The Government may unilaterally increase the number of labor hours
         required to be furnished pursuant to Article B-2, during any one year
         period of performance, by an amount ranging from 1 to 1,935,575 labor
         hours; provided that the cumulative total of option hours exercised
         does not exceed 1,935,575 labor hours for the five year contract
         period. If the Government elects to exercise its option to increase the
         number of labor hours, the Contractor will be notified by a contract
         modification executed by the Contracting Officer. If any option is
         exercised, the number of minimum, target, and maximum labor hours set
         forth in Table B-2 will be increased by the number of hours exercised.
         The estimated cost and available award fee in Article B-3 will be
         increased as follows for each additional labor hour exercised:

                                                   -------          --------

         Failure to exercise any option of the contract shall not be considered
         as a termination for the convenience of the Government. If the
         Government exercises one or any of the options under this contract, the
         contract, as amended, shall include all terms and conditions of the
         contract as it exists immediately prior to the exercise of the
         additional option(s).

ARTICLE B-6 OPTIONS FOR OTHER DIRECT COSTS

In addition to the amount for ODC included in Article B-4 as part of the basic
contract, the Government may increase the amount available for payment of Work
Order related items identified in, or required by, Work Orders issued in
accordance with Attachment J-1, Appendix 3 "Work Order Procedure" by not more
than the total shown below. These items, classified as Other Direct Costs,
include, but are not limited to materials, supplies, equipment, maintenance
services, travel and training. If the Government elects to exercise its option
to increase the amount available for ODC, the Contractor will be notified by a
unilateral Contract Modification executed by the Contracting Officer. Options
increasing the amounts available for ODC may be exercised one or more times, at
any time during the performance period of this contract, provided that the
cumulative total estimated cost exercised does not exceed the amount shown
below. The estimated cost in Article B-3 will be adjusted to reflect the amount
of option exercised.

 ARTICLE B-7      KSC 52.231-90 SPECIAL COST PROVISIONS (MAR 1992) (MODIFIED)

Pursuant to the terms of the contract clause entitled "Allowable Cost and
Payment (NASA Deviation)", the Contractor shall be reimbursed for such actual
and allowable expenditures incurred in the performance of work required by this
contract as may be approved by the Contracting Officer subject to the following
limitations and provisions:

 A.     Travel - Travel required in the performance of work under this contract
        must be in accordance with the Contractor's approved written travel
        policy.

 B.     Provisional Billing Rates and Reimbursement Ceiling Rates

        1.      Provisional billing rates for indirect cost pools shall be set
                at the discretion of the Contracting Officer based upon
                proposals from the Contractor and following review by Government
                auditors. These provisional rates shall be specified in writing
                and may be revised either retroactively or prospectively by the
                Contracting Officer. Prior to each Contractor fiscal year, the
                Contractor shall submit a proposal for the coming year's
                provisional billing rates. If during the course of any
                particular year a significant disparity should arise between the
                approved provisional billing rates and actual rates, the
                Contractor shall submit a proposal requesting consideration for
                revision of the provisional rates to ones more closely
                reflective of the actual rates anticipated for the year. After
                expiration of each of its fiscal years, at the time the
                Contractor submits the final indirect cost rates proposal
                required by paragraph (d)(2) of FAR 52.216-7, "Allowable Cost
                and Payment", the provisional billing rates for the year in

        equitable adjustment in accordance with the clause hereof entitled

               c.      terminate the contract for default.

         2.    Failure to agree on the amount of increased cost to be charged
               to the Contractor or to the reduction in the fee shall be a
               dispute.

H.      Notwithstanding paragraphs F. and G. above, the Government may at any
        time require the Contractor to correct or replace, without cost to the
        Government, nonconforming supplies if the nonconformances are due to (1)
        fraud, lack of good faith, or willful misconduct on the part of the
        Contractor's managerial personnel or (2) the conduct of one or more of
        the Contractor's employees selected or retained by the Contractor after
        any of the Contractor's managerial personnel has reasonable grounds to
        believe that the employee is habitually careless or unqualified.

I.      This clause applies in the same manner to corrected or replacement
        supplies as to supplies originally delivered.

J.      The Contractor shall have no obligation or liability under this contract
        to replace supplies that were nonconforming at the time of delivery
        except as provided in this clause or as may be otherwise provided in the
        contract.

K.      Except as otherwise specified in the contract, the Contractor's
        obligation to correct or replace Government-furnished property shall be
        governed by the clause pertaining to Government property.

A.      Definition. "Services," as used in this clause, includes services
        performed, workmanship, and material furnished or used in performing
        services.

B.      The Contractor shall provide and maintain an inspection system
        acceptable to the Government covering the services under this contract.
        Complete records of all inspection work performed by the Contractor
        shall be maintained and made available to the Government during contract

C.      The Government has the right to inspect and test all services called for
        by the contract, to the extent practicable at all places and times
        during the term of the contract. The Government shall perform
        inspections and tests in a manner that will not unduly delay the work.

D.      If any of the services do not conform with contract requirements, the
        Government may require the Contractor to perform the services again in
        conformity with contract

        requirements, for no additional fee. When the defects in services cannot
        be corrected by reperformance, the Government may (1) require the
        Contractor to take necessary action to ensure that future performance
        conforms to contract requirements and (2) reduce any fee payable under
        the contract to reflect the reduced value of the services performed.

E.      If the Contractor fails to promptly perform the services again or to
        take the action necessary to ensure future performance in conformity
        with contract requirements, the Government may (1) by contract or
        otherwise, perform the services and reduce any fee payable by an amount
        that is equitable under the circumstances or (2) terminate the contract
        for default.

               Kennedy Space Center, FL 32899

        This is the designated billing office for fee vouchers for purposes of
        the Prompt Payment clause of this contract.

D.      In the event that amounts are withheld from payment in accordance with
        provisions of this contract, a separate voucher for the amount withheld
        will be required before payment for that amount may be made.

ARTICLE G-3       NFS 1852.216-76 AWARD FEE FOR SERVICE CONTRACTS (OCT 1996)
                  ALTERNATE I (OCT 1996)

A.      The Contractor can earn award fee from a minimum of zero dollars to the
        maximum stated in Article B-3.

B.      Beginning 12 months after the effective date of this contract, the
        Government will evaluate the Contractor's performance every performance
        period, including option periods exercised pursuant to Article F-2, to
        determine the amount of award fee earned by the Contractor during the
        period. The Contractor may submit a self-evaluation of performance for
        each evaluation period under consideration. These self-evaluations will
        be considered by the Government in its evaluation. The Government's Fee
        Determination Official (FDO) will determine the award fee amounts based
        on the Contractor's performance in accordance with Attachment J-4. The
        plan may be revised unilaterally by the Government prior to the
        beginning of any rating period to redirect emphasis.

C.      The Government will advise the Contractor in writing of the evaluation
        results. The Contracting Officer will issue a unilateral modification to
        the contract that will recognize the award fee earned. The Contractor is
        not required to submit a separate voucher for earned award fee. The Cost
        and Commercial Service Branch, Code GG-B1-A, will make payment based on
        the unilateral modification.

D.      After 85% of the potential award fee has been paid, the Contracting
        Officer may direct the withholding of further payment of award fee until
        a reserve is set aside in an amount that the Contracting Officer
        considers necessary to protect the Government's interest. This reserve
        shall not exceed 15% of the total potential award fee.

E.      The amount of award fee which can be awarded in each evaluation period
        is limited to the amounts set forth in Article B-3. Award fee which is
        not earned in a evaluation period cannot be reallocated to future
        evaluation periods.

F.      1.      Pending a determination of the amount of award fee earned for an
                evaluation period, a portion of the available award fee for that
                period will be paid to the Contractor on a monthly basis. The
                portion paid will be 80% of the current period's available
                amount or the equivalent of the prior period's interim fee,
                whichever is lower; provided, however, that when the Contracting
                Officer determines that the Contractor will not achieve a level
                of performance commensurate with the provisional rate, payment
                of provisional award fee will be discontinued or reduced in such
                amounts as the Contracting Officer deems appropriate. The
                Contracting Officer will notify the Contractor in writing if it
                is determined that such discontinuance or reduction is
                appropriate. This determination is not subject to the Disputes
                clause.

--------------------------------------------------------------------------------

        2.      In the event the amount of award fee earned, as determined by
                the FDO, is less than the sum of the provisional payments made
                for that period, the Contractor will either credit the next
                payment voucher for the amount of such overpayment or refund the
                difference to the Government, as directed by the Contracting
                Officer.

        3.      Provisional award fee payments will be made prior to the first
                award fee determination by the Government.

G.      Award fee determinations made by the Government under this contract are
        not subject to the Disputes clause.

        directed by the Contracting Officer. The respective responsibilities and
        authorities of the above-named representatives are set forth in
        1827.375-3 of the NASA FAR Supplement.

ARTICLE G-5       NFS 1852.242-70 TECHNICAL DIRECTION (SEP 1993)

A.      Performance of the work under this contract is subject to the written
        technical direction of the Contracting Officer's Technical
        Representatives (COTRs), who shall be specifically appointed by the
        Contracting Officer in writing in accordance with NASA FAR Supplement
        1842.270. For purposes of this contract, the COTRs are the Contract
        Technical Manager (CTM) and Technical Representatives (TRs). "Technical
        direction" means a directive to the Contractor that approves approaches,
        solutions, designs, or refinements; fills in details or otherwise
        completes the general description of work or documentation items; shifts
        emphasis among work areas or tasks; or furnishes similar instruction to
        the Contractor. Technical direction includes requiring studies and
        pursuit of certain lines of inquiry regarding matters within the general
        tasks and requirements in Section C of this contract.

B.      The COTR does not have the authority to, and shall not, issue any
        instruction purporting to be technical direction that --

        1.      Constitutes an assignment of additional work outside the
                Statement of Work;

--------------------------------------------------------------------------------

        2.      Constitutes a change as defined in the Changes clause;

        3.      Constitutes a basis for any increase or decrease in the total
                estimated contract cost, the fixed fee (if any), or the time
                required for contract performance;

        4.      Changes any of the expressed terms, conditions, or
                specifications of the contract; or

        5.      Interferes with the Contractor's rights to perform the terms and
                conditions of the contract.

C.      All technical direction shall be issued in writing by the COTR.

D.      The Contractor shall proceed promptly with the performance of technical
        direction duly issued by the COTR in the manner prescribed by this
        clause and within the COTR's authority. If, in the Contractor's opinion,
        any instruction or direction by the COTR falls within any of the
        categories defined in paragraph B. above, the Contractor shall not
        proceed but shall notify the Contracting Officer in writing within 5
        working days after receiving it and shall request the Contracting
        Officer to take action as described in this clause. Upon receiving this
        notification, the Contracting Officer shall either issue an appropriate
        contract modification within a reasonable time or advise the Contractor
        in writing within 30 days that the instruction or direction is --

        1.     Rescinded in its entirety; or

        2.     Within the requirements of the contract and does not constitute a
               change under the Changes clause of the contract, and that the
               Contractor should proceed promptly with its performance.

E.      A failure of the Contractor and the Contracting Officer to agree that
        the instruction or direction is both within the requirements of the
        contract and does not constitute a change under the Changes clause, or a
        failure to agree upon the contract action to be taken with respect to
        the instruction or direction, shall be subject to the Disputes clause of
        this contract.

F.      Any action(s) taken by the Contractor in response to any direction given
        by any person other than the Contracting Officer or the COTR shall be at
        the Contractor's risk.

                advised to complete and submit the required forms as soon as
                practicable after contract award. Within 14 working days after
                the receipt of the forms, the KSC Protective Services Office
                will determine whether the person is eligible for unescorted
                access.

        2.      The Contractor is responsible for providing escort services for
                any of his employees and/or any subcontractor employees who are
                not eligible for unescorted access.

ARTICLE H-12 NFS 1852.209-71 LIMITATION OF FUTURE CONTRACTING (DEC 1988)

A.      The Contracting Officer has determined that this acquisition may give
        rise to a potential organizational conflict of interest. Accordingly,
        the attention of all prospective offerors is invited to FAR Subpart 9.5
        Organizational Conflicts of Interest.

B.      The nature of this conflict is a possible unfair competitive advantage.

C.      The restrictions upon future contracting are described below:

        1.      If the Contractor, under the terms of this contract, or through
                the performance of tasks pursuant to this contract, is required
                to develop specifications or statements of work that are to be
                incorporated into a solicitation, the Contractor shall be
                ineligible to perform the work described in that solicitation as
                a prime or first tier subcontractor under an ensuing NASA
                contract. This restriction shall remain in effect for a
                reasonable time as agreed to by the Contracting Officer and the
                Contractor sufficient to avoid unfair competitive advantage or
                potential bias (this time shall in no case be less than the
                duration of the initial production contract). NASA shall not
                unilaterally require the Contractor to prepare such
                specifications or statements of work under this contract.

        2.      To the extent that the work under this contract requires access
                to proprietary, business confidential, or financial data of
                other companies, and as long as these data remain proprietary or
                confidential, the Contractor shall protect these data from
                unauthorized use and disclosure and agrees not to use them to
                compete with those other companies.

of the Contractor's effort can be objectively measured in terms of technical and
quality achievement, schedule progress or cost performance, will be ordered on a
PBC basis. To the extent that work is ordered on a PBC basis in lieu of a level
of effort basis, an equitable adjustment will be made to the contract.

An ombudsman has been appointed to hear and facilitate the resolution of
concerns from Contractors during the postaward phase of this acquisition. When
requested, the ombudsman will maintain strict confidentiality as to the source
of the concern. The existence of the ombudsman is not to diminish the authority
of the Contracting Officer. Further, the ombudsman does not participate in
adjudication of formal contract disputes. Therefore, before consulting with the
ombudsman, interested parties must first address their concerns, issues,
disagreements, and/or recommendations to the Contracting Officer for resolution.
If resolution cannot be made by the Contracting Officer, interested parties may
contact the Kennedy Space Center ombudsman, who is the Deputy Center Director at
407-867-2355. Concerns, issues, disagreements, and recommendations that cannot
be resolved at the installation may be referred to the NASA ombudsman, the
Deputy Administrator for Procurement, at 202-358-2090. Please do not contact the
ombudsman to clarify technical requirements. Such inquiries shall be directed to
the Contracting Officer or as specified elsewhere in this document.

        3.      Provide for 100 percent employee vesting at the earlier of one
                year of continuous employee service or contract termination; and

        4.      Not be modified, terminated or a new plan adopted without the
                prior written approval of the cognizant NASA Contracting
                Officer.

B.      The Contractor shall include paragraph A. of this clause in all
        subcontracts for continuing services under a service contract if:

        1.      The prime contact requires pension portability;

        2.      The subcontracted labor dollars (excluding any burdens or
                profit/fee) exceed $2,500,000 and ten percent of the total prime
                contract labor dollars (excluding any burdens or profit/fee);
                and

        3.      Either of the following conditions exists:

                i.      There is a continuing need for the same or similar
                        subcontract services for a minimum of five years
                        (inclusive of options), and if the subcontractor
                        changes, a high percentage of the predecessor
                        subcontractor's employees are expected to remain with
                        the program; or

     E.   The Contractor shall additionally provide data, exclusive of narrative
          remarks, on electronic medium. The Contractor and NASA will jointly
          pursue the use of available technologies and transmission capabilities
          to facilitate electronic reporting, and will endeavor to provide
          electronic reporting earlier than the standard due dates.

     F.   The Contractor shall furnish with the initial NF533Q, the Contractor's
          accounting calendar which lists the accounting periods, number of work
          days included in each period, and all holidays. All subsequent
          revisions shall be provided at the time of the change. At a minimum,
          an updated accounting calendar will be provided at the beginning of
          each government fiscal year.

     G.   Data elements listed in this DRD will be reported under the following
          categories:

           1.     Total Contract Summary
                  ----------------------

           2.     Indirect Cost Summary (Management & Administrative)

           4.     Work Order Numbers and Titles
                  -----------------------------

     H.   Contractors are required to indicate full incurred costs on the NF533
          Report. At the end of each fiscal year, upon submittal of final
          indirect cost rates, provisional billing rates shall be changed to the
          proposed final rates. The Contractor shall include all adjustments in
          the current month actual costs column on the NF533M, itemizing
          adjustments in an addendum to the NF533M.

     I.   Cost figures will be reported to the nearest whole dollar, and
          equivalent headcount will be reported to the nearest tenth. Hours will
          be reported to the nearest whole hour.

     J.   Subcontractors, if applicable, will provide 533 reports to the prime
          Contractor in the same format as required by this DRD for the
          applicable data elements and categories. Copies of the subcontractor's
          533 reports will be submitted with the prime contractor's 533 reports.

     K.   Indirect costs (such as management and administrative costs and
          Non-Work Order related ODC) shall be allocated to the applicable Work
          Orders based on acceptable accounting practices and statistical
          techniques. A complete breakdown of all elements of indirect cost and
          allocation methods will be required. Specific percentages and
          distributions must be approved by NASA prior to implementation.

     L.   Each NF533M shall contain a next month estimate for all anticipated
          hours and costs.

     M.   The Contractor shall provide with the NF533M, a variance analysis by
          amount and percent for each element of cost, of the difference between
          the estimate for the month (made in the previous month) and the actual
          for the month being reported in the current NF533M. This variance
          analysis will be required for the Contract Summary, as well as for
          each Appropriation Summary. In addition, the Contractor shall provide
          a narrative summary of each data element and explain the reason(s) for
          the variance.

6.   Block 8. Preparation Information Continued:

     P.   An analysis of Payroll Additives & Fringe Benefits (PA&FB) shall be
          included with each NF533Q. The analysis will detail all elements that
          make up the PA&FB category and list the Fiscal Year to Date Cost for
          each element, and provide an estimate for the balance of the Fiscal
          Year, by quarter. The associated labor cost will also be included, and
          the Fringe Benefit Rate will be calculated as a percent of labor cost.
          The applicable bases, and rates for the individual elements will be
          provided. Variances from planned rates, and variances between quarters
          will be explained.

     Q.   SELECTED DATA ELEMENT DEFINITIONS Elements of cost are defined in
          general in NPG 9501.2C. This Center feels that additional explanations
          are necessary for the items listed below, in order to ensure clarity.

          1.   Straight Time Hours - Those non-premium hours exclusive of
               non-productive hours which are worked by direct labor personnel.

          2.   Overtime Hours - Those premium hours worked by direct labor
               personnel.

          3.   Non-Productive Hours - Those hours used for vacation, sick leave,
               holiday, and other non-work periods. This only includes those
               hours for which the employees are paid.

          4.   Equivalent Direct Headcount - The average number of personnel
               directly performing a specific task or contract (does not include
               indirect personnel), for a given length of time, and is usually
               expressed as a monthly average. It is further defined as:

<TABLE>
<CAPTION>
<S>                       <C>
 Direct Headcount = Straight Time Direct Hours + Non-Productive Hours for Direct Employee
                    -------------------------------------------------------------------------
                          8 x (number of Operating Days and Holidays)
</TABLE>


          5.   Equivalent Indirect Headcount - The average number of indirect
               (Management & Administrative) personnel. Population less direct
               headcount.

          6.   Equivalent Population - The average number of contractor
               personnel located at KSC during the month. The total of Direct
               and Indirect Headcount. It is further defined as:


    Straight Time Direct Hours + Non-Productive Hours + Indirect Hours (M&A)
    -----------------------------------------------------------------------
                  8 x (number of Operating Days and Holidays)

          7.   Equivalent Overtime Headcount -
               -------------------------------

Equivalent Overtime Headcount =    Total Paid Overtime Hours Expended
                                -----------------------------------------
                                8 x (number of Operating Days & Holidays)

         8.  Overtime Rate Percent -
             -----------------------

Overtime Rate =       Overtime Hours Expended
                 ------------------------------------
                 Straight Time Hours + Non-Productive

8. PREPARATION INFORMATION


The Risk Assessment provides a formal means to identify, assess, and mitigate
risks associated with technical, schedule, mission success and cost. A risk
assessment including analytical methods, qualitative and/or quantitative as
appropriate will be developed and delivered when a program risk is identified or
increases.

The assessment should include:

     a.   Identification of the primary risk drivers.
     b.   Qualitative and/or quantitative assessment of the risk including
          probability/likelihood of occurrence and consequences (i.e., increase,
          decrease or no change to present risk posture).
     c.   Option for mitigating the risk including a recommendation.
     d.   Impacts to baselined risk controls

Contractor format is acceptable.

8. PREPARATION INFORMATION


The Contractor shall establish a written, detailed Technology Transfer Plan
setting forth the manner in which the contractor will meet the new technology
reporting requirements of the Patent Rights clause (FAR 52.227-11 as modified by
NFS 1852.227-11). The plan will also identify how the contractor will implement
NASA's technology transfer policy set forth in NASA's "Agenda for Change." The
plan shall address, at a minimum, the following:

1.   Identify the specific areas of technical effort that are considered likely
     to generate new technology.

2.   Describe the means by which project supervisory and technical personnel
     will be advised of the responsibilities, details, and benefits of new
     technology reporting.

3.   Describe the procedures to be established, maintained, and followed for
     reviewing the effort to be undertaken for the purposes of identification
     and reporting (disclosure) of new technology within the time periods and in
     the manner prescribed by the Patent Rights clause.

4.   Describe the procedure for timely submission of the interim and final new
     technology reports required by the Patent Rights clause.

5.   Describe the procedures for (a) selecting either NASA's New Technology
     clause (NFS 1852.227-70) or another patent rights clause for inclusion in
     subcontracts having as a purpose the conduct of experimental,
     developmental, research, design, or engineering work, and (b) providing
     prompt notification of either the award of such subcontracts or a
     subcontractor's refusal to accept the clause.

6.   Identify the individual(s) assigned substantial and specific
     responsibilities for ensuring compliance with the requirements of the
     Patent Rights clause, as well as their qualifications and organizational
     placement to discharge these responsibilities.

6.   Block 8. Preparation Information Continued:

     7.   Establishment of a technology transfer point of contact for
          coordinating all technology transfer activities.

     8.   The Contractor's commitment to the development of cutting-edge dual
          use technologies having both application within and outside of the
          aerospace community.

     9.   Programs aimed at educating and motivating employees to report new
          technology.

     10.  Programs that assist subcontractors in establishing technology
          transfer policies and implementing technology transfer plans.

     11.  Programs that support NASA's outreach and industry assistance efforts
          pertaining to technology transfer.

     12.  Programs aimed at conducting collaborative efforts with third parties
          for the purpose of effectively transferring technology.

     Funding for such collaborative efforts will not necessarily include
     government funds and may consist of totally private funds. These
     collaborative efforts shall be reviewed and, where Government funds are to
     be used, approved by the Contracting Officer. Ownership of rights to the
     technology developed under these collaborative efforts shall be addressed
     in the individual agreements that are negotiated as part of the technology
     transfer process.

     13.  Programs aimed at conducting application engineering work for the
          purpose of adapting the developed technology to a specific commercial
          use.

     14.  Programs that demonstrate a strong management commitment to technology
          transfer.

To maximize the benefits received from the program, it will be necessary to
identify and protect the intellectual property rights associated with the
technology developed under this contract (i.e., patents, copyrights, trade
secrets and know-how). To the extent feasible, the Government agrees to use its
best efforts to transfer rights in government-owned technology in order to
support the Contractor's technology transfer program.

              SAFETY, RELIABILITY AND MAINTAINABILITY REQUIREMENTS

                                  INTRODUCTION

This document incorporates appropriate safety, reliability, and maintainability
provisions of NASA documents: NHB 1700.1, "NASA Safety Manual"; and Vol. 1; NHB
5300.4 (1D-2), "Safety, Reliability, Maintainability and Quality Provisions for
the Space Shuttle Program."

          GENERAL SAFETY, RELIABILITY AND MAINTAINABILITY REQUIREMENTS

1.      The Contractor shall maintain a safety activity planned and developed in
        conjunction with other functions to assure that hazards are identified
        and eliminated or controlled to an acceptable level of risk. In addition
        to the development of a safety plan, safety requirements and tasks will
        be reflected as appropriate in other contract program plans. Applicable
        safety requirements and tasks shall be included in the basic management
        systems, design verification documents, overall system analyses, and
        system engineering requirements definition, and design review practices.

2.      The Contractor shall conduct industrial safety activities in compliance
        with NASA FAR Supplement 1852.223-70. Industrial safety includes, as a
        minimum, identification, elimination, and/or control of hazards in
        employee and public areas; accident prevention, fire prevention and
        protection, and transportation accident prevention for all Contractor
        activities.

3.      Safety requirements for planning, design, manufacturing, testing, and
        operations shall be developed and documented as an integral part of the
        Contractor's activities. The Contractor shall establish checkpoints and
        feedback which provide visibility to management to assure all safety
        issues/concerns have been evaluated and resolved prior to commencement
        of critical activities and major milestones. Safety assessments shall be
        revised and updated as design and operational changes dictate.

4.      Safety activities shall be fully coordinated to ensure an effective and
        integrated total safety effort and to avoid redundant effort among
        technical disciplines.

5.      The Contractor shall support periodic safety activity audits as
        required. The Contractor shall provide data upon request which verifies
        internal conformance and the conformance of subcontractors to safety
        requirements. The Contractor shall maintain audit reports to be made
        available to NASA upon request.

6.      The Contractor shall provide training and certification for personnel
        who are to be involved in hazardous operations and activities. The
        Contractor shall identify positions requiring training and
        certification. A current status of certification shall be maintained
        oriented to missions, configurations, and locations. Protective devices
        and emergency equipment shall be identified and included in safety
        training. Hazards shall be brought to

--------------------------------------------------------------------------------

        the attention of trainees. Proficiency demonstrations of training, to
        the degree feasible, are required for hazardous operations.

7.      The Contractor shall provide the means for reviewing safety status as
        part of each program review. Risk management data shall be made
        available and/or presented at program progress reviews and milestone
        reviews when applicable and/or upon NASA request.

8.      The Contractor shall select and levy safety requirements specified in
        this document, as appropriate, on the subcontractors who provide
        subsystems which, in either normal or emergency operational modes, may
        present hazards impacting system or personnel safety.

9.      The Contractor shall establish and identify procedures and instructions
        which shall be used to execute all safety analyses. The Contractor shall
        perform system safety analyses assuring that:

        A.      Safety is designed into the product; known hazardous conditions
                which cannot be eliminated through equipment design or
                operational procedures are controlled or reduced to an
                acceptable level. Residual hazards shall be tracked and
                identified to NASA.

        B.      Provide continuous tracking and status of hazard severity; the
                aim being to reduce catastrophic and critical hazards to
                controlled levels within the constraints of risk management.

        C.      Results of previous trade studies and analyses are considered.

        D.      Other related analyses, such as Failure Modes and Effects
                Analyses (FMEA), are considered to preclude duplication of
                analytical work.

10.     The Contractor shall perform safety studies and shall develop safety
        inputs to support trade studies. Specific, inherently hazardous
        characteristics of the alternatives being considered shall be
        identified. The Contractor shall document rationale to support the
        selected concept and to demonstrate that it includes the optimum safety
        provisions consistent with program objectives, risk management,
        performance, cost, and schedules.

11.     For proposed waivers and deviations, the Contractor shall establish a
        means to analyze the safety impact. Submissions of safety variance
        requests shall be in accordance with KHB 1710.2C, Annex B, "KSC Safety
        Practices Handbook."

12.     The Contractor shall assure safe methods are implemented for handling
        hardware to assure that it is not damaged during operations.

13.     The Contractor shall comply with, and submit a statement verifying the
        compliance of all the Occupational Safety and Health Administration
        Standards, Part 1910, Sub-parts D, F and N, in addition to any
        applicable KSC safety regulations, for safety-critical handling
        hardware, and personnel walking and work platforms.

14.     When changes are proposed for equipment design or procedures, the
        Contractor shall identify and resolve hazards that may be introduced
        into the system. All hazards, including residual hazards, shall be
        identified as part of the engineering change evaluation/risk assessment
        process.

15.     Provisions shall be made to assure adequate validation tests are
        performed on critical devices or components to determine the degree of
        hazard or margin of safety of design. These types of tests will be
        specified in the development and verification requirements.

16.     The Contractor shall review test plans for ground testing and flight
        testing of critical space flight and ground equipment when directed to
        assure tests are adequate to identify and assess potential hazards,
        protect personnel, and avoid damage to test articles and facilities.

17.     Observation of designated hazardous tests/operations shall be performed
        as necessary to ensure adherence to safety principles and compliance
        with safety requirements and checklists. The Government safety
        representative retains the authority to stop work/tests at any time. The
        Contractor safety representative also has the authority to stop
        work/tests due to unsafe/hazardous conditions. The authority to resume
        work/tests resides with the safety organization initiating the stop
        work/test.

18.     Detailed test procedures and related documents for hazardous or high
        cost tests/operations shall be reviewed and approved by the Contractor's
        designated responsible safety personnel and approved by NASA Safety. In
        the event the Contractor places personnel in hyperbaric and altitude
        chambers or other similar type hazardous facilities, applicable safety
        requirements shall be met. Documents dealing with hazardous operations
        shall be in place and available a minimum of ten days prior to there

        as necessary.

                       SPECIFIC SOFTWARE SAFETY STANDARDS

                                  Introduction

This Software Assurance Standard is based on NASA-STD-220lWC as modified for the
effort under this contract. This is a stand-alone document prepared using
NASA-STD-2201 WC as a basis.

1.      Scope

         This Standard specifies the software assurance program for the provider
         of operational software products. It also delineates the assurance
         activities for the provider.

------------
(3) Operational Software - All flight software and ground software that either:
(1) interfaces with on-orbit elements in real-time, (2) is critical to the
mission (such as all control center, test, and certification software, including
associated models and simulators); (3) Software Support Environment (SSE)
software that interfaces with on-orbit elements in real-time or is critical to
the mission; and/or (4) software within ground support equipment (GSE) that
interfaces with on-orbit elements in real-time or firmware (embedded software
that commands and controls GSE).

                              Work Order Procedure
                              --------------------

1.  Work Orders and Work Order Revisions
    ------------------------------------
    a.  Implementing documents to define work to be performed within the
        limitations of the contract will be issued by the NASA Contracting
        Officer (CO). This implementing document is a Work Order (WO), KSC Form
        2-132 (C/G 2/97). WOs are normally filled out by Technical Contacts
        (TCs) and approved by Technical Representatives (TRs).

    b.  Each WO sets forth the scope of the work to be performed, including
        travel, training and technical requirements. The WO establishes a labor
        hour limit, outside procurement and Other Direct Costs (ODC) limit,
        total funding limit and required completion date. Funding limits and
        required completion dates shall not be exceeded without prior approval
        of the Contract Technical Manager (CTM). Each such approval must be
        documented by a revision to the WO, using the same form. Work shall not
        commence unless the WO or revised WO is signed by the CTM and the CO. In
        emergency cases, verbal authority to proceed may be granted by the CTM.
        In such cases, written WO authorization will be issued within 48 hours
        (2 working days).

    c.  Work Orders may also contain Standards of Performance (SOP), Maximum
        Error Rates (MER) and performance metrics to be reported. A Standard of
        Performance defines mid-excellent range (~95) performance for a
        particular element or metric. A Maximum Error Rate defines performance
        in the mid-satisfactory range (~65) for a particular element or metric.
        Metrics will define how to measure performance against the SOPs and
        MERs, and will be used by the TRs and CTM as a tool in the evaluation of
        the Contractor's performance of the WO. Work Orders may also contain
        Critical Milestones. The Contractor's success in accomplishing Critical
        Milestones will be tracked by the CTM as a contract-wide metric.

    d.  The Contractor, upon receipt of a WO or revised WO, shall acknowledge
        receipt by returning one signed copy to the CTM, CO, Resource Management
        Office (RMO), Project Control Office (DE-PCO) and each TR named in the
        document within two working days after receipt. In the event the
        Contractor does not agree with the requirements, funding limits,
        Critical Milestones, or other elements of the WO, the Contractor shall
        proceed with performance and provide the TR a written assessment and
        recommendations within two working days of receipt of the WO. The TR
        will revise the WO, if necessary, or notify the Contractor that no
        changes were deemed necessary, within two working days of receiving the
        written assessment. Issues which cannot be resolved between the
        Contractor and the TR within four working days following TR receipt of
        the written assessment should be presented to the CTM for resolution.
        Unresolved matters will be referred to the CO. Any differences must be
        resolved between the parties and the WO revised to reflect the
        agreement.

--------------------------------------------------------------------------------

    e.  Unless noted otherwise on the WO, the Contractor shall submit a Work
        Plan, per DRD-030, describing how the work will be accomplished,
        including the technical approach, resources required and recommended
        metrics.

    f.  A subsidiary document to WOs is a Technical Directive (TD) (KSC Form
        21-156). TDs will be issued by TCs and TRs to the Contractor via the CTM
        where it is necessary to provide more specific details within the scope
        of the WO. The use of TDs shall be confined to the substance of the
        work. All TDs shall be in writing. TDs do not require signature
        acknowledgment by the Contractor. Questions concerning the propriety of
        a TD or its contents, effectivity, applicability, etc., shall be
        referred to the CTM for resolution. Unresolved matters will be referred
        to the CO.

    g.  Upon completion of a WO, the Contractor shall sign the WO, and forward
        the original WO to the CTM. The Contractor shall forward copies of the
        signed, closed-out WO to the CO and TR.

    h.  During the life of a WO, the Contractor shall maintain a close-out
        folder of historical records of significant activity involving the WO.
        Upon completion of the WO, the closeout folder shall serve as a
        permanent WO record that has potential value to any follow-on effort and
        shall be maintained in accordance with disposition schedules in
        NHB 1441.1 (as revised). The close-out folder shall be retained by the
        Contractor for the duration of the contract (including all exercised
        options or extensions), at which time it shall be turned over to the
        Federal Records Center for disposition in accordance with applicable
        schedules in NHB 1441.1 (as revised).

            INFORMATION TECHNOLOGY (I/T) PLANNING AND REVIEW AT KSC,
            --------------------------------------------------------

                              PRINCIPLES AND GOALS

The KSC "plan and review" policy applies to all direct-funded I/T capital
acquisitions whether for and/or by civil servants or contractors, and whether
the contractors are support or mission/program.

The criteria for review by the Chief Information Officer (CIO) Office is based
on Agency regulation and standardization, KSC standardization, unnecessary
replication, and cost. While, for procurement reasons, we also require a general
technical justification, this Office questions technical need only when it is
clear that there may be a misunderstanding or error in the description of the
I/T needed to accomplish the mission of the organization.

The basis of review revolves around a description of the order or acquisition
and a set of seven questions which must be answered for each. However, the
description and questions can be scoped to an entire project or task and not to
each order or acquisition therein. The answers to these questions (the "I/T
justification") are generally simple, and in any event, encompass and satisfy
both procurement and standards rules and regulations.

                       Required Information for I/T Plans

The following I/T Plan information must be provided in sufficient detail (high
level for Level A, detailed for Level B) to justify each resource acquisition:

      Resource Identification - Provide Plan name, Data Processing Installation
      (DPI), System, Project, and Contract name, as applicable.

      Transaction Description - Describe each transaction (i.e., all I/T
      resource purchases, project or grouped purchases, or other contract I/T
      expenditures); include product details (name, model, quantities, etc.);
      and indicate whether any purchases are for Civil Service use or use as
      Government Furnished Equipment (GFE). Each transaction in a plan should
      also be assigned a unique transaction number for later referral.

      Cost Estimates - Provide estimated costs of transactions, separated into
      the categories of Hardware, Software, Support Services, Commercial
      Services (e.g., timesharing) and I/T Supplies. Also, indicate which costs
      are competitive, compatibility limited, or sole source.

      Technical Justification - Provide a brief explanation of why this
      transaction is needed. Also, include additional explanation if purchasing
      a non-standard product, or for compatibility limited or sole-source
      purchases.

      Hardware & Software transactions must also answer these seven questions as
      appropriate:

          1.  Is this part of a defined R&D Program (include Project Title)?

          2.  Why can't you get along with what you have?

--------------------------------------------------------------------------------

          3.  Why can't we get along with what we have? (pool or redistribute)

          4.  Why can't it be satisfied with a solution that costs less?

          5.  How does it save NASA money? (business case)

          6.  Why can't you use what everybody else is using? (standards)

          7.  What  is your  plan  for  "waterfalling"  replaced  equipment  or
              software?  (excessing) (Include explanation if no excess results
              from this transaction.)

            [NOTE: Where practical, please group transactions with common
            justifications and answers to the seven questions into groups or
            "Projects." If answer to question one is yes, you may skip questions
            two through seven]

       Purchase Approach - Indicate whether the transaction is a NASA or
       Contractor Purchase (include contract or contractor name). Also, indicate
       if acquisition is competitive, compatibility limited, or sole source.

       Purchase Schedule - Indicate purchase schedule ("year" is sufficient for
       Level A plans; month or specific date for level B.)

       Certification Statements - Each Plan must also explicitly provide the
       following certifications signed by the organization CIO and Director in
       order to comply with existing regulations & policies:

          1.  In submitting this I/T Plan, the organizational CIO or Technical
              Manager has considered necessary measures for safeguarding
              sensitive, personal, and other official Government information.

          2.  All I/T  acquisitions in this I/T Plan are required to
              accomplish the mission of this organization.

          3.  All I/T acquired under this plan will be utilized on site at KSC.
              (If not, attach an explanation).

A unique plan number should be assigned to each plan based on the organization
code followed by the date. Further Procurement documents (PRs & SRs) should
reference the plan number and appropriate transaction numbers within your plan.
No I/T resource purchases can proceed unless clearly included in an approved
plan. We recognize that I/T Plans are living documents, and expect some degree
of ongoing change and modification. Additional documentation such as sole source
justifications or software conversion studies will still need to be provided
when appropriate.

Electronic copies of all plans and presentation materials shall be provided to
the CTM in standard MS-Office product format (Word, Excel, PowerPoint, etc.) for
attachment to the Engineering Development Directorate I/T plan.

APPLICABLE TO WEATHER OBSERVERS ONLY - NIGHT PAY & SUNDAY PAY: If you work at
night as a part of a regular tour of duty, you will earn a NIGHT DIFFERENTIAL
and receive an additional 10% of basic pay for any hours worked between 6pm and
6am. If you are a fulltime employee (40 hours a week) and Sunday is part of your
regularly scheduled workweek, you are paid at your rate of basic pay plus a
Sunday premium of 25% of your basic rate for each hour of Sunday work which is
not overtime (i.e. occasional work on Sunday outside the normal tour of duty is
considered overtime work).

                             ** UNIFORM ALLOWANCE **

If employees are required to wear uniforms in the performance of this contract
(either by the terms of the Government contract, by the employer, by the state
or local law, etc.), the cost of furnishing such uniforms and maintaining (by
laundering or dry cleaning) such uniforms is an expense that may not be borne by
an employee where such cost reduces the hourly rate below that required by the
wage determination. The Department of Labor will accept payment in accordance
with the following standards as compliance:

The contractor or subcontractor is required to furnish all employees with an
adequate number of uniforms without cost or to reimburse employees for the
actual cost of the uniforms. In addition, where uniform cleaning and maintenance
is made the responsibility of the employee, all contractors and subcontractors
subject to this wage determination shall (in the absence of a bona fide
collective bargaining agreement providing for a different amount, or the
furnishing of contrary affirmative proof as to the actual cost), reimburse all
employees for such cleaning and maintenance at a rate of $4.2 5 per week (or
$.85 cents per day). However, in those instances where the uniforms furnished
are made of "wash and wear" materials, may be routinely washed and dried with
other personal garments, and do not require any special treatment such as dry
cleaning, daily washing, or commercial laundering in order to meet the
cleanliness or appearance standards set by the terms of the Government contract,
by the contractor, by law, or by the nature of the work, there is no requirement
that employees be reimbursed for uniform maintenance costs.

REQUEST FOR AUTHORIZATION OF ADDITIONAL CLASSIFICATION AND WAGE RATE (Standard
Form 1444 (SF 1444))

Conformance Process:

The contracting officer shall require that any class of service employee which
is not listed herein and which is to be employed under the contract (i.e., the
work to be performed is not performed by any classification listed in the wage
determination), be classified by the contractor so as to provide a reasonable
relationship (i.e., appropriate level of skill comparison) between such unlisted
classifications and the classifications listed in the wage determination. Such
conformed classes of employees shall be paid the monetary wages and furnished
the fringe benefits as are determined. Such conforming process shall be
initiated by the contractor prior to the performance of contract work by such
unlisted class(es) of employees. The conformed classification, wage rate, and/or
fringe benefits shall be retroactive to the commencement date of the contract.
{See Section 4.6 (C)(vi)} When multiple wage determinations are included in a
contract, a separate SF 1444 should be prepared for each wage determination to
which a class(es) is to be conformed.

The process for preparing a conformance request is as follows:

1) When preparing the bid, the contractor identifies the need for a conformed
occupation(s) and computes a proposed rate(s).

2) After contract award, the contractor prepares a written report listing in
order proposed classification title(s), a Federal grade equivalency (FGE) for
each proposed classification(s), job description(s), and rationale for proposed
wage rate(s), including information regarding the agreement or disagreement of
the authorized representative of the employees involved, or where there is no
authorized representative, the employees themselves. This report should be
submitted to the contracting officer no later than 30 days after such unlisted
class(es) of employees performs any contract work.

3) The contracting officer reviews the proposed action and promptly submits a
report of the action, together with the agency's recommendations and pertinent
information including the position of the contractor and the employees, to the
Wage and Hour Division, Employment Standards Administration, U.S. Department of
Labor, for review. (See section 4.6(b)(2) of Regulations 29 CFR Part 4).

4) Within 30 days of receipt, the Wage and Hour Division approves, modifies, or
disapproves the action via transmittal to the agency contracting officer, or
notifies the contracting officer that additional time will be required to
process the request.

5) The contracting officer transmits the Wage and Hour decision to the
   contractor.

6) The contractor informs the affected employees.

Information required by the Regulations must be submitted on SF 1444 or bond
paper.

When preparing a conformance request, the "Service Contract Act Directory
of Occupations" (the Directory) should be used to compare job definitions to
insure that duties requested are not performed

by a classification already listed in the wage determination. Remember, it is
not the job title, but the required tasks that determine whether a class is

                          EDC AWARD FEE EVALUATION PLAN

1.   Introduction
     ------------

     A.   Purpose

          The purpose of the Award Fee Plan is to encourage and reward the
          Contractor for safe, high quality, cost-conscious performance in
          fulfilling the requirements set forth in this contract; to provide
          flexibility for changes in management and performance emphasis; and to
          promote effective communications.

          The use of award fee permits the Government to focus on overall
          technical and cost performance and to emphasize those aspects of
          critical milestone achievements essential to reach mission objectives.

     B.   Award Fee Determinations

          Award fee determinations, up to the maximum potential amounts
          specified in the contract schedule, will be made by the Fee
          Determination Official (FDO). Award fee determinations will be based
          on both objective metrics and subjective judgments by the Government
          of the Contractor's performance using procedures and evaluation
          criteria as specified in this Award Fee Plan.

2. Evaluation Procedure
   --------------------

     For the purpose of award fee determinations on this contract, the procedure
     indicated below will be followed.

     A.   General

          (I) Award fee will be determined annually by the Fee Determination
              Official who is Chairperson of the Contract Award Fee Board
              (CAFB). The CAFB is comprised of the FDO, the Engineering
              Development Director, other line management directors, the
              Director of Safety and Mission Assurance, the Procurement Officer
              or Deputy, and the KSC Chief Financial Officer or designee.

          (2) The award fee will be determined based upon a review by the CAFB
              of the consolidated recommendation prepared by the Contract
              Technical Manager (CTM), the Contracting Officer (CO), and the
              Contractor's additional data, if any.

          (3) The CTM will be the focal point for the accumulation and
              development of award fee evaluation reports, reviews, and
              presentations as well as discussions with Contractor management on
              award fee matters.

          (4) The determination of award fee shall be unilateral and shall not
              be subject to the Disputes clause of the contract.

--------------------------------------------------------------------------------
     B. Reviews

          The Contractor's performance will be reviewed in the manner described
          below.

          (1)  Concurrent - Contractor performance levels which require remedial
               attention or which may be expected to adversely affect award fee
               ratings will be made known to the Contractor by the CTM (either
               orally or in writing) on a current basis.

          (2)  Quarterly - A quarterly review of the Contractor's performance
               will be held by the CTM with cognizant evaluators. The substance
               of this quarterly review will be summarized in writing and a copy
               transmitted to the Contractor.

          (3) Annually - Within thirty (30) calendar days following each
              performance period, the CTM will prepare a report on the
              evaluation of the Contractor's performance. The Contractor will be
              furnished a copy of the report without an adjective rating or
              numerical score assigned for the period. Within ten (10) calendar
              days from receipt of the evaluation report, the Contractor may, if
              so desired, submit in writing to the CTM additional data bearing
              on the performance evaluation. The Contractor's comments, if any,
              will be included in the final report to the CAFB. The Contractor
              may also request an opportunity to give a presentation to the CAFB
              concerning his performance.

 3.  Fee Determination
     -----------------

     A.   The CAFB will convene to review the award fee evaluation report,
          Contractor's comments, and such other information as may be
          appropriate. After consideration of this data, the CAFB will assist
          the FDO in determining an appropriate amount of award fee.

     B.   The FDO will notify the Contracting Officer in writing of the amount
          of award fee, if any, determined to have been earned during the
          evaluation period. The Contracting Officer will notify the Contractor
          of such determination. This determination is not subject to appeal
          under the Disputes clause or any other provision of the contract.

     C.   Following notification of the award fee determination, the Contacting
          Officer will issue a modification to the contract.

4. Evaluation Criteria

    A.  Evaluation criteria encompass the safety, quality, timeliness,
        efficiency, and cost effectiveness of the Contractor's performance of
        contract requirements. Appropriate areas of emphasis will be established
        for each evaluation period emphasizing effective accomplishment of
        contract activities and mission success. The specific areas of directed
        emphasis will be identified and communicated to the Contractor at least
        fifteen (15) days prior to the start of the evaluation period by the
        Contracting Officer.


                                      130
<PAGE>   132
     B.   The Contracting Officer may notify the Contractor at a later date of
          alterations in areas of emphasis (including additions or deletions).
          Such alterations will be prospective and will allow the Contractor
          time to react or implement the alterations.

 5.  Numerical Ranges/Adjective Definitions and Award Fee Scale

     Exhibits to this Plan set forth the adjective ratings, definitions, and
     associated numerical ranges to be used to define the various levels of
     performance under the contract. The Award Fee Scale sets forth in tabular
     form the award fee earned at various performance ratings.

                                        of contract requirements is of
                                        exceptional merit marked by timely,
                                        efficient, and economical performance.
                                        Exemplary performance in all areas of
                                        directed emphasis. Very minor
                                        deficiencies with no adverse effect on
                                        overall performance.
       81 - 90        VERY GOOD         The Contractor is exhibiting very
                                        effective performance and is fully
                                        responsive to contract requirements.
                                        Majority of performance requirements
                                        are timely, efficient, and economically
                                        conducted. Only minor deficiencies
                                        are noted.
      71 - 80            GOOD           The Contractor is performing
                                        effectively and is fully responsive to
                                        contract requirements. There are
                                        reportable deficiencies which have
                                        minor identifiable effect on overall
                                        contract performance.
      61 - 70        SATISFACTORY       The Contractor meets or slightly
                                        exceeds the minimum acceptable
                                        contract requirements with adequate
                                        results. There are reportable
                                        deficiencies with identifiable, but not
                                        substantial, effects on overall contract
                                        performance.
      60 AND        UNSATISFACTORY      The Contractor does not meet

1.      Pursuant to Contract Article B-5, OPTIONS TO EXTEND THE PERIOD OF
        CONTRACT AND OPTIONS FOR INCREMENTAL INCREASE OF EFFORT, the Government
        unilaterally increases the number of man-hours required by 134,000 for
        the period October 1, 1997 through September 30, 1998. A table for
        tracking exercised option hours has been incorporated in this article.

2.      Contract Article B-3, CONTRACT VALUE, for the period 10/1/97 through
        9/30/98 is increased by $3,615,320 (134,000 option man-hours @ the
        contract option hours labor rate of $26.98 - no fee).

3.      Contract Article B-12, NFS 1852.232-81 CONTRACT FUNDING (JUN 1990). The
        columns for Cost Other and Total Cost & Fee are corrected to reflect
        error in addition on a previous modification.

4.      Address changes on both the prime and subcontractor are made on the
        SF30.

As a result of the above changes, pages 7, 8, 9 and 13 of said contract, as
modified, are deleted and replacement pages 7, 8,9 and 13 are substituted in
lieu thereof.

ARTICLE B-1 TYPE OF CONTRACT
            ----------------

This is a cost-plus-award-fee, term form of contract with a level of effort
basis. The Contractor is obligated to provide Engineering, Engineering Support,
and Facilities and Laboratory Support. Specific requirements will be levied on
the Contractor by Work Orders in accordance with the Statement of Work (SOW),
Attachment J-1.

ARTICLE B-2 EFFORT REQUIRED DURING CONTRACT PERFORMANCE
            --------------------------------------------

A.      The Contractor shall provide non-personal services for NASA as described
        in Article C-1, "Scope of Work" and Attachment J-1, "Statement of Work"
        on a level of effort (LOE) basis. In performance of the described work
        during the contract period set forth below, the Contractor shall not
        exceed the total labor hours on the contract, including subcontractor
        and overtime hours.

B.      If the Contractor has not provided the specified minimum quantity of
        total contract labor hours set forth in the above paragraph A, an
        equitable downward adjustment will be made in estimated cost and
        available award fee. The downward adjustment will be based on the
        difference between the minimum labor hours specified under this Article
        and the number of labor hours provided by the Contractor. This provision
        does not affect the Government's right to reduce the quantity of labor
        hours during the term of this contract pursuant to the Termination
        Clause (FAR 52.249-6).

C.      When the total labor hours expended reach 95% of the maximum labor hours
        specified above, the Contractor shall notify the Contracting Officer as
        to whether or not the Contractor believes that amount will be sufficient
        for the balance of the period of performance, or if additional labor
        hours will be required. In the latter case, the notification shall
        include the estimated "adequate through" date for the unexpended balance
        and an estimate of the additional hours required for the balance of the
        period of performance. If, during the term of the contract, an increase
        in the specified maximum number of labor hours becomes necessary, the
        Government may elect to increase the

D.      As used herein, the term "labor hours" shall include the productive and
        non-productive time of the employees assigned to this contract
        (including subcontracted and overtime labor hours).

ARTICLE B-4 OTHER DIRECT COSTS
            ------------------
Notwithstanding the provisions of Article G-7 entitled "Base Support", the
Contractor may be required to provide Work Order related items identified in, or
required by, Work Orders issued in accordance with Attachment J-1, Appendix 3
"Work Order Procedure." These items, classified as Other Direct Costs, include,
but are not limited to, materials, supplies, equipment, maintenance services,
travel, and training. This action is authorized only if such items/services are
not available pursuant to Article G-7 entitled "Base Support." The estimated
cost of this contract includes the amount of $5,000,000 in the basic contract
period and $5,000,000 in each of the four option periods for the acquisition of
such items or services. The costs covered by this article shall be separately
accumulated and reported in accordance with DRD-003. Such costs are considered
non-fee-bearing.

ARTICLE B-5 OPTIONS TO EXTEND THE PERIOD OF CONTRACT AND
            --------------------------------------------
            OPTIONS FOR INCREMENTAL INCREASE OF EFFORT
            --------------------------------------------

A.      Options to Extend the Period of Contract

        1.      This contract is renewable for the periods identified as options
                in Table B-3 at the option of the Government.

        2.      The Government may extend the term of the contract for the
                quantities of supplies or services and period specified in the
                Schedule by written modification of this contract before the
                current contract performance period expires, provided that the
                Government will give the Contractor a preliminary written notice
                of intent to extend at least 60 days prior to expiration of any
                current period of performance. The preliminary notice does not
                commit the Government to exercise the option.

        3.      If the Government exercises any Option, the extended contract
                shall be considered to include this option provision.


                                                             Modification No. 10
                                                                     Page 4 of 6

--------------------------------------------------------------------------------

        4.      The total duration of this contract, including the exercise of
                any option(s) under this clause, shall not exceed five (5)
                years.

        5.      It is understood and agreed that any continued performance of
                services from period to period shall be at the sole
                determination of the Government and will be contingent upon
                prior satisfactory performance. Failure to renew the contract
                for any subsequent period of performance shall not be
                considered as a termination for the convenience of the
                Government.

B.      Options for Incremental Increase of Effort

        The Government may unilaterally increase the number of labor hours
        required to be furnished pursuant to Article B-2, during any one year
        period of performance, by an amount ranging from 1 to 1,935,575 labor
        hours; provided that the cumulative total of option hours exercised does
        not exceed 1,935,575 labor hours for the five year contract period. If
        the Government elects to exercise its option to increase the number of

--------------------------------------------------------------------------------

        Items or services acquired under this contract are required to include
        accurate processing of the date and date-related data (including but not
        limited to calculating, comparing, and sequencing) by all hardware and
        software products delivered under this contract, individually and in
        combination, upon installation. This also includes the manipulation of
        data with dates prior to, through, and beyond January 1, 2000, and shall
        be transparent to the use.

        Hardware and software products provided under this contract shall,
        individually, and in combination, successfully transition into the Year
        2000 with the correct system date, without human intervention, including
        leap year calculations. Such products shall also provide correct results
        when moving forward or backward in time across the Year 2000 or
        subsequent years.

        Year 2000 Compliance

        (a)     "Year 2000 compliant," as used herein, means that the
                information technology (hardware, software and firmware,
                including embedded systems or any other electro-mechanical or
                processor-based systems used in accordance with its associated
                documentation) accurately processes date and date-related data
                (including, but not limited to, calculating, comparing and
                sequencing) from, into, and between the twentieth and
                twenty-first centuries, and the years 1999 and 2000 and leap
                year calculations, to the extent that other information
                technology, used in combination with the information technology
                being acquired, property exchanges date and date-related data
                with it.

        (b)     Any information technology provided, operated and/or maintained
                under this contract must be Year 2000 compliant. To ensure this
                result, the Contractor shall provide documentation describing
                how the IT items or services demonstrate Year 2000 compliance,
                consisting of: a certification document signed by the vendor
                and/or original equipment manufacturer for commercial items. For
                IT items or services developed or built, or commercial items
                integrated into a viable package by the contractor, the
                contractor shall provide a certification document and integrated
                test results demonstrating Year 2000 compliance.

        (c)     Milestones for Renovation, Validation and Implementation: Any IT
                determined to be non-Year 2000 compliant shall be replaced,
                retired, or repaired in accordance with the following schedule:

                1.      "Renovation" includes making and documenting software
                        and hardware changes, developing replacement systems,
                        and decommissioning systems to be retired. The
                        Contractor must complete renovation of affected
                        software, hardware and firmware by September 30, 1998.

                2.      "Validation" includes unit, integration, system and
                        end-to-end testing for Year 2000 compliance. The
                        Contractor must complete validation and testing of

A. The purpose of this modification is to reflect a cost variance between the
negotiated estimated cost and the estimated cost to complete the work which
resulted from the skill mix requirements driven by the Government Task Orders
from contract inception to September 30, 1998. This interim adjustment is made
to align contract value with cumulative contract costs and funding.

B. As a result of the above changes, pages 7, 8, 9, 13 and 14 of the contract
are hereby deleted and new pages 7, 8, 9, 9.1, 13 and 14 are substituted in lieu
thereof.

                      Supplies or Services and Prices/Cost

ARTICLE B-1 TYPE OF CONTRACT

This is a cost-plus-award-fee, term form of contract with a level of effort
basis. The Contractor is obligated to provide Engineering, Engineering Support,
and Facilities and Laboratory Support. Specific requirements will be levied on
the Contractor by Work Orders in accordance with the Statement of Work (SOW),
Attachment J-1.

ARTICLE B.2 EFFORT REQUIRED DURING CONTRACT PERFORMANCE

A.      The Contractor shall provide non-personal services for NASA as described
        in Article C-1 "Scope of Work" and Attachment J-1, "Statement of Work"
        on a level of effort (LOE) basis. In performance of the described work
        during the contract period set forth below, the Contractor shall not
        exceed the total labor hours on the contract, including subcontractor
        and overtime hours.

B.      If the Contractor has not provided the specified minimum quantity of
        total contract labor hours set forth in the above paragraph A, an
        equitable downward adjustment will be made in estimated cost and
        available award fee. The downward adjustment will be based on the
        difference between the minimum labor hours specified under this Article
        and the number of labor hours provided by the Contractor. This provision
        does not affect the Government's right to reduce the quantity of labor
        hours during the term of this contract pursuant to the Termination
        Clause (FAR 52.249-6).

C.      When the total labor hours expended reach 95% of the maximum labor hours
        specified above, the Contractor shall notify the Contracting Officer as
        to whether or not the Contractor believes that amount will be sufficient
        for the balance of the period of performance, or if additional labor
        hours will be required. In the latter case, the notification shall
        include the estimated "adequate through" date for the unexpended balance
        and an estimate of the additional hours required for the balance of the
        period of performance. If, during the term of the contract, an increase
        in the specified maximum number of labor hours becomes necessary, the
        Government may elect to increase the maximum labor hours pursuant to
        Article B-5, "Options to Extend the Period of Contract and Options for
        Incremental Increase of Effort".

D.      As used herein, the term "labor hours" shall include the productive and
        non-productive time of the employees assigned to this contract
        (including subcontracted and overtime labor hours).

ARTICLE B-4 OTHER DIRECT COSTS
            ------------------

Notwithstanding the provisions of Article G-7 entitled "Base Support", the
Contractor may be required to provide Work Order related items identified in, or
required by, Work Orders issued in accordance with Attachment J-1, Appendix 3
"Work Order Procedure." These items, classified as Other Direct Costs, include,
but are not limited to, materials, supplies, equipment, maintenance, services,
travel, and training. This action is authorized only if such items/services are
not available pursuant to Article G-7 entitled "Base Support." The estimated
cost of this contract includes the amount of $5,000,000 in the basic contract
period and $5,000,000 in each of the four option periods for the acquisition of
such items or services. The costs covered by this article shall be separately
accumulated and reported in accordance with DRD-003. Such costs are considered
non-fee-bearing.


                                                             Modification No. 12

ARTICLE B-5 OPTIONS TO EXTEND THE PERIOD OF CONTRACT AND
            --------------------------------------------
            OPTIONS FOR INCREMENTAL INCREASE OF EFFORT
            ------------------------------------------

A.      Options to Extend the Period of Contract

        1.      This contract is renewable for the periods identified as options
                in Table B-3 at the option of the Government.

        2.      The Government may extend the term of the contract for the
                quantities of supplies or services and period specified in the
                Schedule by written modification of this contract before the
                current contract performance period expires, provided that the
                Government will give the Contractor a preliminary written notice
                of intent to extend at least 60 days prior to expiration of any
                current period of performance. The preliminary notice does not
                commit the Government to exercise the option.

        3.      If the Government exercises any option, the extended contract
                shall be considered to include this option provision.

        4.      The total duration of this contract, including the exercise of
                any option(s) under this clause, shall not exceed five (5)
                years.

        5.      It is understood and agreed that any continued performance of
                services from period to period shall be at the sole
                determination of the Government and will be contingent upon
                prior satisfactory performance. Failure to renew the contract
                for any subsequent period of performance shall not be considered
                as a termination for the convenience of the Government.

B.      Options for Incremental Increase of Effort

        The Government may unilaterally increase the number of labor hours
        required to be furnished pursuant to Article B-2, during any one year
        period of performance, by an amount ranging from 1 to 1,935,575 labor
        hours; provided that the cumulative total of option hours exercised does
        not exceed 1,935,575 labor hours for the five year contact period. If
        the Government elects to exercise its option to increase the number of
        labor hours, the Contractor will be notified by a contact modification
        executed by the Contracting Officer. If any option is exercised, the
        number of minimum, target, and maximum labor hours set forth in Table
        B-2 will be increased by the number of hours exercised. The estimated
        cost and available award fee in Article B-3 will be increased as follows
        for each additional labor hour exercised:

--------------------------------------------------------------------------------

         Failure to exercise any Option of the contract shall not be considered
         as a termination for the convenience of the Government. If the
         Government exercises one or any of the options under this contract, the
         contract, as amended, shall include all terms and conditions of the
         contract as it exists immediately prior to the exercise of the
         additional option(s).

For historical tracking purposes, the following table is established to document

ARTICLE B-6 OPTIONS FOR OTHER DIRECT COSTS
            ------------------------------

In addition to the amount for ODC included in Article BA as part of the basic
contract, the Government may increase the amount available for payment of Work
Order related items identified in, or required by, Work Orders issued in
accordance with Attachment J-1, Appendix 3 "Work Order Procedure" by not more
than the total shown below. These items, classified as Other Direct Costs,
include, but are not limited to materials, supplies, equipment, maintenance
services, travel and training. If the Government elects to exercise its option
to increase the amount available for ODC, the Contractor will be notified by a
unilateral Contract Modification executed by the Contracting Officer. Options
increasing the amounts available for ODC may be exercised one or more times, at
any time during the performance period of this contract, provided that the
cumulative total estimated cost exercised does not exceed the amount shown
below. The estimated cost in Article B-3 will be adjusted to reflect the amount

A.  The purpose of this modification is to normalize the maximum labor hours
    identified in the contract for each optional contract period to reflect
    productive labor, inclusive of subcontractor labor hours and overtime, only.
    The conversion is necessary to relate the Task Order productive effort to
    contract value productive authority for incentive fee evaluation purposes.
    The results of this normalization of hours are reflected in the attached
    revised contract page 7.1.


B.  The estimated cost for the option periods as depicted on page 8.2.1, Table
    B-3.A remain unchanged by this modification. However, the direct labor rate
    as depicted on page 9.1, Table B-5.B require adjustment for proper
    calculation of estimated cost of incremental increase of effort during the
    option periods. The results of these rate adjustments are reflected on the
    attached revised page 9.1, Table B-5.B.


C.  The available award fee and target incentive fee amounts as depicted on page
    8.2.1, Table B-3.C remain unchanged by this modification. However, the
    available award fee and target incentive fee rates are hereby changed to
    reflect the impact of the revised base of productive hours for proper
    calculation of available fee for incremental increases of effort during the
    option periods. The results of these adjustments are reflected on the
    attached revised page 9.1, Table B-5.B.

It has been recognized that NASA may require the Contractor to perform design,
contract surveillance, construction, and modification of facilities functions.
It is anticipated that these construction of facilities efforts will be
incidental to the associated research and development activities required under
the Contract. The purpose of this modification is to add this additional scope
to the statement of work and to incorporate the associated contract clauses as
follows:


A.  ARTICLE B-12 NFS 1582.232-81 CONTRACT FUNDING (JUN 1990) is revised to apply
    the provisions of the "Limitations of Funds" Clause separately to each
    construction of facilities effort. A full text version of the revised
    contract clause is reflected on the attached revised page 13. In addition, a
    new Contract Table B-12 A Facilities Projects: Values and Funding, which
    delineates the level of funding provided by NASA for the accomplishment of
    each construction effort, is attached as a new contract page 14 A.

B.  Contract Section I, ARTICLE I-1, FAR 52.252-2 CLAUSES INCORPORATED BY
    REFERENCE (JUN 1988) has been updated to incorporate the FAR Construction
    Clauses. The attached replacement / new contract pages 38, 38 A, 38 B, and
    39, define these additional clauses.

C.  The scope of work as defined in Contract Attachment J-1, Statement of Work,
    has been revised to include services for the design, contract surveillance,
    construction and modification to facilities. Statement of Work replacement
    pages 49, 50, and 51 are attached hereto.

B.      If the Contractor has not provided the specified minimum quantity of
        total contract labor hours set forth in the above paragraph A, an
        equitable downward adjustment will be made in estimated cost and
        available award fee. The downward adjustment will be based on the
        difference between the minimum labor hours specified under this Article
        and the number of labor hours provided by the Contractor. This provision
        does not affect the Government's right to reduce the quantity of labor
        hours during the term of this contract pursuant to the Termination
        Clause (FAR 52.249-6).

C.      When the total labor hours expended reach 95% of the maximum labor hours
        specified above, the Contractor shall notify the Contracting Officer as
        to whether or not the Contractor believes that amount will be sufficient
        for the balance of the period of performance, or if additional labor
        hours will be required. In the latter case, the notification shall
        include the estimated "adequate through" date for the unexpended balance
        and an estimate of the additional hours required for the balance of the
        period of performance. If, during the term of the contract, an increase
        in the specified maximum number of labor hours becomes necessary, the
        Government may elect to increase the maximum labor hours pursuant to
        Article B-5, "Options to Extend the Period of Contract and Options for
        Incremental Increase of Effort".


                                                             Modification No. 12

D.      As used herein, the term "labor hours" shall include the productive and
        non-productive time of the employees assigned to this contract
        (including subcontracted and overtime labor hours).

ARTICLE B-3 CONTRACT VALUE

period and $5,000,000 in each of the four option periods for the acquisition of
such items or services. The costs covered by this article shall be separately
accumulated and reported in accordance with DRD-003. Such costs are considered
non-fee-bearing.

--------------------------------------------------------------------------------

ARTICLE B-5 OPTIONS TO EXTEND THE PERIOD OF CONTRACT AND
            OPTIONS FOR INCREMENTAL INCREASE OF EFFORT

A.      Options to Extend the Period of Contract

        1.      This contract is renewable for the periods identified as options
                in Table B-3 at the option of the Government.

        2.      The Government may extend the term of the contract for the
                quantities of supplies or services and period specified in the
                Schedule by written modification of this contract before the
                current contract performance period expires, provided that the
                Government will give the Contractor a preliminary written notice
                of intent to extend at least 60 days prior to expiration of any
                current period of performance. The preliminary notice does not
                commit the Government to exercise the option.

        3.      If the Government exercises any option, the extended contract
                shall be considered to include this option provision.

        4.      The total duration of this contract, including the exercise of
                any option(s) under this clause, shall not exceed five (5)
                years.

        5.      It is understood and agreed that any continued performance of
                services from period to period shall be at the sole
                determination of the Government and will be contingent upon
                prior satisfactory performance. Failure to renew the contract
                for any subsequent period of performance shall not be considered
                as a termination for the convenience of the Government.

B.      Options for Incremental Increase of Effort

        The Government may unilaterally increase the number of labor hours
        required to be furnished pursuant to Article B-2, during any one year
        period of performance, by an amount ranging from 1 to 1,935,575 labor
        hours; provided that the cumulative total of option hours exercised does
        not exceed 1,935,575 labor hours for the five year contact period. If
        the Government elects to exercise its option to increase the number of
        labor hours, the Contractor will be notified by a contact modification
        executed by the Contracting Officer. If any option is exercised, the
        number of minimum, target, and maximum labor hours set forth in Table
        B-2 will be increased by the number of hours exercised. The estimated
        cost and available award fee in Article B-3 will be increased as follows
        for each additional labor hour exercised:

increasing the amounts available for ODC may be exercised one or more times, at
any time during the performance period of this contract, provided that the
cumulative total estimated cost exercised does not exceed the amount shown

A.  The purpose of this modification is to exercise the option period commencing
    October 1, 1999 through September 30, 2000. The estimated contract value, as
    shown on Table B-3.A, for option period 10/01/99 - 9/30/00 in the amount of

    contract value for this option period.

B.  In addition, this modification incrementally funds this contract with an
    additional $2,200,031.00. Table B-12 has been updated to reflect the
    allotment of this addition incremental funding.

C.  As a result of these changes, Tables B-3.A and B-12 (pages 8.1 and 14) of
    the subject contract, as revised, are hereby deleted in their entirety and
    the enclosed Tables B-3.A and B-12 (pages 8.1 and 14) are substituted in

A.  The purpose of this modification is to normalize the maximum labor hours
    identified in the contract for each optional contract period to reflect
    productive labor, inclusive of subcontractor labor hours and overtime, only.
    The conversion is necessary to relate the Task Order productive effort to
    contract value productive authority for incentive fee evaluation purposes.
    The results of this normalization of hours are reflected in the attached
    revised contract page 7.1.


B.  The estimated cost for the option periods as depicted on page 8.2.1, Table
    B-3.A remain unchanged by this modification. However, the direct labor rate
    as depicted on page 9.1, Table B-5.B require adjustment for proper
    calculation of estimated cost of incremental increase of effort during the
    option periods. The results of these rate adjustments are reflected on the
    attached revised page 9.1, Table B-5.B.


C.  The available award fee and target incentive fee amounts as depicted on page
    8.2.1, Table B-3.C remain unchanged by this modification. However, the
    available award fee and target incentive fee rates are hereby changed to
    reflect the impact of the revised base of productive hours for proper
    calculation of available fee for incremental increases of effort during the
    option periods. The results of these adjustments are reflected on the
    attached revised page 9.1, Table B-5.B.

It has been recognized that NASA may require the Contractor to perform design,
contract surveillance, construction, and modification of facilities functions.
It is anticipated that these construction of facilities efforts will be
incidental to the associated research and development activities required under
the Contract. The purpose of this modification is to add this additional scope
to the statement of work and to incorporate the associated contract clauses as
follows:


A.  ARTICLE B-12 NFS 1582.232-81 CONTRACT FUNDING (JUN 1990) is revised to apply
    the provisions of the "Limitations of Funds" Clause separately to each
    construction of facilities effort. A full text version of the revised
    contract clause is reflected on the attached revised page 13. In addition, a
    new Contract Table B-12 A Facilities Projects: Values and Funding, which
    delineates the level of funding provided by NASA for the accomplishment of
    each construction effort, is attached as a new contract page 14 A.

B.  Contract Section I, ARTICLE I-1, FAR 52.252-2 CLAUSES INCORPORATED BY
    REFERENCE (JUN 1988) has been updated to incorporate the FAR Construction
    Clauses. The attached replacement / new contract pages 38, 38 A, 38 B, and
    39, define these additional clauses.

C.  The scope of work as defined in Contract Attachment J-1, Statement of Work,
    has been revised to include services for the design, contract surveillance,
    construction and modification to facilities. Statement of Work replacement
    pages 49, 50, and 51 are attached hereto.
