          June 15, 2002                             33 1/3%

</TABLE>

              If the Advisor ceases to be Chairman of the Board or the boards of
advisors or directors, as applicable, of any of the Company's Subsidiaries for
any reason, the cumulative percentage of the Class C Common and Preferred Units
to become vested will be determined on a pro rata basis according to the number
of days elapsed from the prior June 15 through the date of his resignation or
removal (the "Termination"). Units of Class C Common and units of Preferred
Units which have become vested are referred to herein as "Vested Interests," and
all other units of Class C Common and units of Preferred Units are referred to
herein as "Unvested Interests."

              Upon the consummation of a Change of Control or a Sale of the
Company, all Unvested Interests shall automatically vest.

       6.     Repurchase Option on Advisor Interests. In the event the Advisor
ceases to serve as Chairman of the Board or the boards of advisors or directors,
as applicable, of any Subsidiary for any reason, the Advisor Securities (whether
held by the Advisor or one or more of the Advisor's transferees) will be subject
to repurchase by the Company and Sleep Investor (or its designees) pursuant to
the terms and conditions set forth in this Section 6 (the "Repurchase Option").

              (a)    (i) The purchase price for each Unvested Interest of
Advisor Securities will be the lower of (X) the Advisor's Original Cost for such
unit (with units having the lowest cost subject to repurchase prior to units
with a higher cost) and (Y) the Fair Value for such unit, (ii) the purchase
price for each Vested Interest of Advisor Securities will be the Fair Value for
such unit; and (iii) notwithstanding the foregoing, if the Advisor's Termination
is for Cause or by the voluntary resignation of the Advisor on or prior to June
15, 2003, then the purchase price for

                                      -7-
<PAGE>   8

each Vested Interest and each Unvested Interest will be the lower of (X) the
Advisor's Original Cost for such unit (with units having the lowest cost subject
to repurchase prior to units with a higher cost) and (Y) the Fair Value for such
unit.

              (b)    The Board may elect to cause the Company to purchase (i)
all or a portion of the Unvested Interests and/or, (ii) all or a portion of the
Vested Interests by delivering written notice (the "Repurchase Notice") to the
holder or holders of the Advisor Securities within 45 days after the
Termination. The Repurchase Notice will set forth the number of Unvested
Interests and Vested Interests to be acquired from each holder, the aggregate
consideration to be paid for such securities and the time and place for the
closing of the transaction. The number of units of Advisor Securities to be
repurchased by the Company shall first be satisfied to the extent possible from
the Advisor Securities held by the Advisor at the time of delivery of the
Repurchase Notice. If the number of Advisor Securities then held by the Advisor
is less than the total number of units of Advisor Securities the Company has
elected to purchase, the Company shall purchase the remaining Advisor Securities
elected to be purchased from the other holder(s) of Advisor Securities, pro rata
according to the amount of such Advisor Securities held by such other holder(s)
at the time of delivery of such Repurchase Notice (determined as nearly as
practicable to the nearest share). The number of Unvested Interests and Vested
Interests to be repurchased hereunder will be allocated among the Advisor and
the other holders of Advisor Securities (if any) pro rata according to the
number of units of Advisor Securities to be purchased from such Persons.

              (c)    If for any reason the Company does not elect to purchase
all of the units of Advisor Securities that are subject to the Repurchase
Option, pursuant to such Repurchase Option, Sleep Investor (or its designees)
shall be entitled to exercise the Repurchase Option for the Advisor Securities
the Company has not elected to purchase (the "Available Securities"). Of the
Available Securities, the Vested Interests are referred to herein as "Available
Vested Interests" and Unvested Interests are referred to herein as "Available
Unvested Interests". As soon as practicable after the Company has determined
that there will be Available Securities, but in any event within 90 days after
the Termination, the Company shall give written notice (the "Option Notice") to
Sleep Investor (or its designees) setting forth the number of Available Vested
Interests, Available Unvested Interests, and the purchase price for each of such
Available Securities. Sleep Investor (or its designees) may elect to purchase
all or a portion of (i) Available Vested Interests, and/or (ii) all or a portion
of the Available Unvested Interests by giving written notice to the Company
within 30 days after the Option Notice has been given by the Company. As soon as
practicable, and in any event within ten days after the expiration of the 30-day
period set forth above, the Company shall notify each holder of Advisor
Securities as to the number of Vested Interests or Unvested Interests being
purchased from such holder by Sleep Investor (or its designees) (the
"Supplemental Repurchase Notice"). At the time the Company delivers the
Supplemental Repurchase Notice to the holder(s) of such Advisor Securities, the
Company shall also deliver written notice to Sleep Investor (or its designees)
setting forth the number of Vested Interests and Unvested Interests which Sleep
Investor (or its designees) is entitled to purchase, the aggregate purchase
price and the time and place of the closing of the transaction.

              (d)    The closing of the purchase of the Advisor Securities
pursuant to the Repurchase Option shall take place on the date designated by the
Company in the Repurchase Notice or Supplemental Repurchase Notice, which date
shall not be later than the 60th day after

                                      -8-
<PAGE>   9

the delivery of the later of such notices to be delivered (or, if later, the
15th day after the Fair Value is finally determined) nor earlier than the fifth
day after such delivery. The Company and/or Sleep Investor (or its designee)
will pay for the Advisor Securities to be purchased pursuant to the Repurchase
Option by delivery of a certified or cashier's check or wire transfer of funds.
The purchasers of Advisor Securities hereunder will be entitled to receive
customary representations and warranties from the sellers as to title, authority
and capacity to sell.

              (e)    Notwithstanding anything to the contrary contained in this
Agreement, all repurchases of Advisor Securities by the Company shall be subject
to applicable legal restrictions. If any such restrictions prohibit the
repurchase of Advisor Securities hereunder which the Company is otherwise
entitled to make, the Company may make such repurchases as soon as it is
permitted to do so under such restrictions.

       7.     Restrictions on Transfer.

              (a)    If certificated, the Advisor Securities will bear the
following legend:

              "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
              REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
              "ACT"), AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN
              EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR AN EXEMPTION
              FROM REGISTRATION THEREUNDER. THE SECURITIES REPRESENTED BY THIS
              CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
              TRANSFER, CERTAIN REPURCHASE OPTIONS AND CERTAIN OTHER AGREEMENTS
              SET FORTH IN AN ADVISOR AND UNIT PURCHASE AGREEMENT BETWEEN THE
              ISSUER AND THE SIGNATORY THERETO DATED AS OF JUNE 30, 2000. A COPY
              OF SUCH AGREEMENT MAY BE OBTAINED BY THE HOLDER HEREOF AT THE
              ISSUER'S PRINCIPAL PLACE OF BUSINESS WITHOUT CHARGE."

              (b)    No holder of Advisor Securities may sell, transfer or
dispose of any units of Advisor Securities (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an opinion of counsel (reasonably acceptable in form and substance to
the Company) that neither registration nor qualification under the Securities
Act and applicable state securities laws is required in connection with such
transfer.

              (c)    Each holder of Advisor Securities agrees not to effect any
sale or distribution of any Advisor Securities or other equity securities of the
Company, or any securities convertible into or exchangeable or exercisable for
any of the Company's equity securities, during the seven days prior to and the
180 days after the effectiveness of any underwritten public offering, except as
part of such underwritten public offering or if otherwise permitted by the
Company.

                                      -9-
<PAGE>   10

              (d)    Each holder of Advisor Securities acknowledges that the
Advisor Securities are subject to additional restrictions contained in the
Securityholders Agreement.

       8.     Representations and Warranties of the Company. The Company hereby
represents and warrants to the Advisor that:

              (a)    Immediately following the consummation of the transactions
contemplated hereby, the authorized units of the Company shall consist of (i)
Class A Common, of which 8,511.22 units shall be issued and outstanding, (ii)
Class B Common, of which no units shall be issued and outstanding, (iii) Class C
Common, of which 7,667.24 units shall be issued and outstanding, and (iv)
Preferred Units, of which 37,606.10 units shall be issued and outstanding. As of
immediately following the consummation of the transactions contemplated hereby,
all of the outstanding units of the Company shall be validly issued, fully paid
and nonassessable.

              (b)    There are no statutory or contractual securityholders
preemptive rights or rights of refusal with respect to the issuance of the
Advisor Security hereunder. To the best of the Company's knowledge, the Company
has not violated any applicable federal or state securities laws in connection
with the offer, sale and issuance of the Advisor Securities hereunder do not
require registration under the Securities Act or any applicable state securities
laws. To the best of the Company's knowledge, there are no agreements between
the Company's members with respect to the voting or transfer of the Company's
securities, except for (a) the Securityholders Agreement, (b) the Registration
Rights Agreement and (c) this Advisor and Unit Purchase Agreement, and (d)
certain agreements among the Company, Sleep Investor and certain of the
Company's employees or executives.

       9.     Confidential Information. The Advisor acknowledges that the
information and data obtained by him during his relationship or interaction with
the Company Group concerning the business or affairs of the Company Group
("Confidential Information") are the property of such member of the Company
Group. Therefore, the Advisor agrees that, except as required by law or court
order, he shall not disclose to any unauthorized person or use for his own
account any Confidential Information without the prior written consent of the
Board, unless and to the extent that the aforementioned matters become generally
known to and available for use by the public other than as a result of the
Advisor's acts or omissions to act. The Advisor shall deliver to the Company
upon his resignation as Chairman of the Board or removal from such position, or
at any other time the Company may request, all memoranda, notes, plans, records,
reports, computer tapes and software and other documents and data (and copies
thereof) relating to the Confidential Information, Work Product (as defined
below) and the business of the Company Group which he may then possess or have
under his control.

       10.    Noncompete, Nonsolicitation.

              (a)    The Advisor acknowledges that in the course of his service
as Chairman of the Board and interaction with the Company he has become
familiar, and he will become familiar, with the Company Group's trade secrets
and with other Confidential Information and that his services have been and will
be of special, unique and extraordinary value to the Company Group. Therefore,
the Advisor agrees that, during the time he serves as Chairman and for a period
of one (1) year thereafter (the "Post-Termination Period"), he shall not
directly or

                                      -10-
<PAGE>   11

indirectly own, operate, manage, control, participate in, consult with, advise,
provide services for, or in any manner engage in any business (including by
himself or in association with any person, firm, corporate or other business
organization or through any other entity) in competition with, or potential
competition with, the businesses of the Company Group as such businesses exist
or are in process on the date of resignation or removal of the Advisor as
Chairman of the Board, within any geographical area in which the Company Group
engages or has written plans to engage in such businesses. Nothing herein shall
prohibit the Advisor from being a passive owner of not more than 2% of the
outstanding stock of a corporation which is publicly traded, so long as the
Advisor has no active participation in the business of such corporation.

              (b)    From the date hereof through the Post-Termination Period,
the Advisor shall not directly or indirectly through another entity (i) induce
or attempt to induce any employee or independent contractor of the Company Group
to leave the employ or contracting relationship of the Company Group, or in any
way interfere with the relationship between the Company Group and any employee
or independent contractor thereof, including without limitation, inducing or
attempting to induce any union, employee or group of employees to interfere with
the business or operations of the Company Group, (ii) solicit for employment or
as an independent contractor or hire any person who was an employee or
independent contractor of the Company Group at any time during the period that
the Advisor serves as Chairman of the Board, or (iii) induce or attempt to
induce any customer, supplier, distributor, franchisee, licensee or other
business relation of the Company Group to cease doing business with the Company
Group, or in any way interfere with the relationship between any such customer,
supplier, distributor, franchisee, licensee or business relation and the Company
Group.

              (c)    The Advisor agrees that: (i) the covenants set forth in
this Section 10 are reasonable in geographical and temporal scope and in all
other respects, (ii) the Company Group would not have entered into this
Agreement but for the covenants of the Advisor contained herein, and (iii) the
covenants contained herein have been made in order to induce the Company Group
to enter into this Agreement.

              (d)    If, at the time of enforcement of this Section 10, a court
shall hold that the duration, scope or area restrictions stated herein are
unreasonable under circumstances then existing, the parties agree that the
maximum duration, scope or area reasonable under such circumstances shall be
substituted for the stated duration, scope or area and that the court shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area permitted by law.

              (e)    The Advisor recognizes and affirms that in the event of his
breach of any provision of Section 10, money damages would be inadequate and the
Company Group would have no adequate remedy at law. Accordingly, the Advisor
agrees that in the event of a breach or a threatened breach by him of any of the
provisions of Section 10, the Company Group, in addition and supplementary to
other rights and remedies existing in its favor, may apply to any court of law
or equity of competent jurisdiction for specific performance and/or injunctive
or other relief in order to enforce or prevent any violations of the provisions
hereof (without posting a bond or other security).

              (c)    Severability. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,

illegal or unenforceable provision had never been contained herein.

              (d)    Complete Agreement. This Agreement, the Securityholders
Agreement and the Registration Rights Agreement embody the complete agreement
and understanding among the parties and supersede and preempt any prior

                                      -13-

VALIDITY AND INTERPRETATION OF THIS AGREEMENT AND THE EXHIBITS HERETO WILL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF
NEW YORK, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW

specifically, to recover damages and costs (including reasonable attorneys'
fees) caused by any breach of any provision of this Agreement and to exercise

to any court of law or equity of competent jurisdiction (without posting any
bond or deposit) for specific performance and/or other injunctive relief in
order to enforce or prevent any violations of the provisions of this Agreement.

                     ELECTION TO INCLUDE SECURITIES IN GROSS
                     INCOME PURSUANT TO SECTION 83(b) OF THE
                              INTERNAL REVENUE CODE

              The undersigned purchased units of Class C Common and units of
Preferred Units (the "Advisor Securities"), of Sleepmaster Holdings L.L.C.
("Holdings") on June 30, 2000. Under certain circumstances, Holdings has the
right to repurchase the Advisor Securities at cost from the undersigned (or from
the holder of the Advisor Securities, if different from the undersigned) should
the undersigned cease to be employed by the Company Group and its subsidiaries.

                              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

          Contract Period            Minimum          Target         Maximum
          ---------------            -------          ------         -------
          10/1/97 - 9/30/98          375,502         387,115         398,728
          Option Periods
          10/1/98 - 9/30/99          375,502         387,115         398,728
          10/1/99 - 9/30/00          375,502         387,115         398,728
          10/1/00 - 9/30/01          375,502         387,115         398,728
          10/1/01 - 9/30/02          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).

The fee allocation rate for optional labor hours exercised pursuant to Article
B-5 shall be the rate applicable to the current contract period as specified
therein.

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-l, 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.

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:

                                                   -------          --------
           10/01/00 - 09/30/01                     $ 29.28          $   0.00
                                                   -------          --------
           10/01/01 - 09/30/02                     $ 30.14          $   0.00

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

         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
                question shall be changed to the proposed final rates, subject
                to the reimbursement ceiling rates specified in the contract,
                and the Contractor shall adjust its billings accordingly.

        2.      Notwithstanding the terms of the contract clause entitled
                "Allowable Cost and Payment," the Contractor shall not be
                reimbursed for General and Administrative Costs in excess of the
                following ceilings:

        "Supplies," as used in this clause, includes but is not limited to raw
        materials, components, intermediate assemblies, end products, lots of
        supplies, and, when the contract does not include the Warranty of Data
        clause, data.

 B.     The Contractor shall provide and maintain an inspection system
        acceptable to the Government covering supplies, fabricating methods, and
        special tooling under this contract. Complete records of all inspection
        work performed by the Contractor shall be maintained and made available
        to the Government during contract performance and for as long afterwards
        as the contract requires.

 C.     The Government has the right to inspect and test the contract supplies,
        to the extent practicable at all places and times, including the period
        of manufacture, and in any event before acceptance. The Government may
        also inspect the plant or plants of the Contractor or any subcontractor
        engaged in the contract performance. The Government shall perform
        inspections and tests in a manner that will not unduly delay the work.

 D.     If the Government performs inspection or test on the premises of the
        Contractor or a subcontractor, the Contractor shall furnish and shall
        require subcontractors to furnish all reasonable facilities and
        assistance for the safe and convenient performance of these duties.

 E.     Unless otherwise specified in the contract, the Government shall accept
        supplies as promptly as practicable after delivery; and supplies shall
        be deemed accepted 60 days after delivery, unless accepted earlier.

 F.     At any time during contract performance, but no later than 6 months (or
        such other time as may be specified in the contract) after acceptance of
        the supplies to be delivered under the contract, the Government may
        require the Contractor to replace or correct any supplies that are
        nonconforming at time of delivery. Supplies are nonconforming when they
        are defective in material or workmanship or are otherwise not in
        conformity with

                                       18

NAS10-98001 (EDC)                                                      Section E
--------------------------------------------------------------------------------

        contract requirements. Except as otherwise provided in paragraph H.
        below, the cost of replacement or correction shall be included in
        allowable cost, determined as provided in the Allowable Cost and Payment
        clause, but no additional fee shall be paid. The Contractor shall not
        tender for acceptance supplies required to be replaced without
        disclosing the former requirement for replacement or correction and,
        when required, shall disclose the corrective action taken.

G.      1.     If the Contractor fails to proceed with reasonable promptness to
               perform required replacement or correction, the Government may--

               a.      by contract or otherwise, perform the replacement or
                       correction and charge to the Contractor any increased
                       cost or make an equitable reduction in any fee paid or
                       payable under the contract;

               b.      require delivery of undelivered supplies at an equitable
                       reduction in any fee paid or payable under the contract;
                       or

               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.

ARTICLE E-3 FAR 52.246-5 INSPECTION OF SERVICES--COST- REIMBURSEMENT (APR 1984)

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
        performance and for as long afterwards as the contract requires.

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.

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

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.

B.      Reports of reportable items, and disclosure of subject inventions,
        interim reports, final reports, utilization reports, and other reports
        required by the clause, as well as any correspondence with respect to
        such matters, should be directed to the New Technology Representative
        unless transmitted in response to correspondence or request from the
        Patent Representative. Inquiries or requests regarding disposition of
        rights, election of rights, or related matters should be directed to the
        Patent Representative. This clause shall be included in any subcontract
        hereunder requiring a New Technology clause or Patent Rights Retention

        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.

 ARTICLE G-6       NFS 1852.245-77 LIST OF INSTALLATION-PROVIDED PROPERTY AND
                   SERVICES (MAR 1989)

                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.

        3.      All requests for unescorted access by subcontractors will be

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.

ARTICLE H-13 TECHNOLOGY TRANSFER PROGRAM

A.      The Contractor shall support, and participate in, the Government's
        Technology Transfer/Commercialization Program by assisting the transfer
        of technology developed under government contract to the private sector.
        The Contractor's participation may include a number of different
        activities including the following:

        1.      Dual-use development of cutting edge technology having
                applications both within and outside the aerospace community.

        2.      Collaborative efforts with third parties for the purpose of
                transferring technology.

        3.      Government sponsored technology outreach and industry assistance
                programs that further the transfer of technology.

        4.      Applications engineering work for the purpose of adapting the
                developed technology to a specific use.

B.      All projects and associated agreements will be coordinated with the CTM,
        DE-TPO, and directed in writing by the Contracting Officer. Agreements
        will state funding requirements, project description, scope of project,
        reporting requirements, and responsible NASA and contractor personnel.
        Ownership of rights to the technology developed under these
        collaborative and partnership activities shall be addressed in the
        individual agreements. Projects utilizing government funds will be
        approved by the Contracting Officer.

C.      Contractor commitment to technology transfer/commercialization can be
        demonstrated by the development of internal programs aimed at:

        1.      Education and training its workforce in technology transfer
                activities.

        2.      Motivating its employees to report new technology as required by
                FAR 52.227-11 as modified by NFS 1852.227-11.

to, waste storage and disposal coordination in accordance with KMI 8800.8, "KSC
Environmental Management."

ARTICLE H-15 PERFORMANCE BASED WORK ORDERS

Prior to Work Order issuance, each work requirement will be examined by the
Government to determine whether it is appropriate for Performance Based
Contracting (PBC). Effort that can be contractually defined so that the results
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

ARTICLE I-10 NFS 1852.237-71 PENSION PORTABILITY (JAN 1997)

A.      In order for pension costs attributable to employees assigned to this
        contract to be allowable costs under this contract, the plans covering
        such employees must:

        1.      Comply with all applicable Government laws and regulations;

        2.      Be a defined contribution plan, or a multiparty defined benefit
                plan operated under a collective bargaining agreement. In either
                case, the plan must be portable, i.e., the plan follows the
                employee, not the employer;

        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

                   subcontract consolidating existing services is awarded, and
                   the total subcontract period covered by the plan covers a
                   minimum of five years (including both the predecessor and
                   successor subcontracts).

          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.

The GIDEP Alert System notifies all organizations of problems associated with
GSE items which could cause loss of GSE, flight hardware or personnel.

The Alert System shall:
-----------------------

     a.   Identify an individual Contractor Alert point of contact.
     b.   Review nonconformance and other failure documentation to determine if
          there is a problem which requires initiation and distribution of an
          Alert.
     c.   Immediately notify the KSC Alert contact point (EI-F-C) of Alert
          problems.
     d.   Provide follow-up notification by sending completed Alert Report (DD
          Form 1938) to the KSC Alert contact.

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

                       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

            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?

                                       114

NAS10-98001 (EDC)                                     Attachment J-1, Appendix 5
--------------------------------------------------------------------------------

          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

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

                          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.

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).

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.

                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

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:

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

        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

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.

        Table B-2

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).

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).

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

A.      The contract value is comprised of estimated cost and award fee as shown
        in Table B-3. The Contractor may earn award fee at the end of the twelve
        month basic period of performance and any twelve month option period, if
        exercised.

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

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:

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

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
    $17,699,862 was utilized as the basis for establishing the estimated
    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
    lieu thereof.

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.
