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

         (4) Requests for extension of the time for disclosure election, and
filing under subparagraphs (c)(1), (2), and (3) of this clause may, at the
discretion of the agency, be granted.

(d) Conditions when the Government may obtain title. The Contractor will convey
to the Federal agency, upon written request, title to any subject invention--

         (1) If the Contractor fails to disclose or elect title to the subject
invention within the tunes specified in paragraph (c) of this clause, or elects
not to retain title, provided, that the agency may only request title within 60
days after learning of the failure of the Contractor to disclose or elect
within the specified tines.

         (2) In those countries in which the Contractor fails to file patent
applications within the times specified in paragraph (c) of this clause;
provided however, that if the Contractor has filed a patent application in a
country after the times specified in paragraph (c) of this clause, but prior to
its receipt of the written request or the federal agency, the Contractor shall
continue to retain title in that country.

         (3) In any country in which the Contractor decides not to continue the
prosecution of any application for, to pay the maintenance fees on, or defend in
reexamination or opposition proceeding on, a patent on a subject invention.

(e) Minimum rights to Contractor and protection of the Contractor right to file.

         (1) The Contractor will retain a nonexclusive royalty-free license
throughout the world in each subject invention to which the Government obtains
title, except if the Contractor fails to disclose the invention within the times
specified in paragraph (c) of this clause. The Contractor's license extends to
its domestic subsidiary and affiliates, if any, within the corporate structure
of which the Contractor is a party and includes the right to grant sublicenses
of the same scope to the extent the Contractor was legally obligated to do so at
the time the contract was awarded. The license is transferable only with the
approval of the federal agency, except when transferred to the successor of that
part of the Contractor's business to which the invention pertains.

         (2) The Contractor's domestic license may be revoked or modified by the
funding Federal agency to the extent necessary to achieve expeditious practical
application of subject invention pursuant to an application for an exclusive
license submitted in accordance with applicable provisions at 37 CFR Part 404

that field of use or the geographical areas in which the Contractor has achieved
practical application and continues to make the benefits of the invention
reasonably accessible to the public. The license in any foreign country may be
revoked or modified at the discretion of the funding Federal agency to the
extent the Contractor, its licensees, or the domestic subsidiaries or affiliates
have failed to achieve practical application in that foreign country.

         (3) Before revocation or modification of the license, the funding
Federal agency will furnish the Contractor a written notice of its intention to
revoke or modify the license, and the Contractor will be allowed 30 days (or
such either time as may be authorized by the funding Federal agency for good
cause shown by the Contractor) after the notice to show cause why the

                                N00178-03-C-1013                   Page 23 of 26
--------------------------------------------------------------------------------

license should not be revoked or modified. The Contractor has the right to
appeal, in accordance with applicable regulations in 37 CFR Part 404 and agency
regulations if any, concerning the licensing of Government-owned inventions, any
decision concerning the revocation or modification of the license.

(f) Contractor action to protect the Government's interest.

         (1) The Contractor agrees try execute or to have executed and promptly
deliver to the Federal agency all instruments necessary to (i) establish or
confirm the rights the Government has throughout, the world in those subject
inventions to which the Contractor elects to retain title, and (ii) convey title
to the Federal agency when requested under paragraph (d) of this clause and to
enable the Government to obtain patent protection throughout the world in that
subject invention.

         (2) The Contractor agrees to require, by written agreement, its
employees, other than clerical and nontechnical employee's, to disclose
promptly in writing to personnel identified as responsible for the
administration of patent matters and in a format suggested by the Contractor
each subject invention made under contract in order that the Contractor can
comply with the disclosure provisions of paragraph (c) of this clause, and to
execute all papers necessary to file patent applications on subject inventions
and to establish the Government's rights in the subject inventions. This
disclosure format should require, as a minimum, the information required by
subparagraph (c)(1) of this clause. The Contractor shall instruct such
employees, through employee agreements or other suitable educational programs,
on the importance of reporting inventions in sufficient time to permit the
filing of patent applications prior to U.S. or foreign statutory bars.

         (3) The Contractor will notify the Federal agency of any decisions not
to continue the prosecution of a patent application, pay maintenance fees, or
defend in a reexamination or opposition proceeding on a patent, in any country,
now less than 30 days before the expiration of the response period required by
the relevant patent office.

         (4) The Contractor agrees to include, within the specification of any
United States patent application and any patent issuing thereon covering a
subject invention, the following statement, "This invention was made with
Government support under (identify the contract) awarded by (identify the
Federal agency). The Government has certain rights in the invention."

(g) Subcontracts.

         (1) The Contractor will include this clause, suitably modified to
identify the parties, in all subcontracts, regardless of tier, for experimental,
developmental, or research work to be performed by a small business firm or
domestic nonprofit organization. The subcontractor will retain all rights
provided for the Contractor in this clause, and the Contractor will not, as part
of the consideration for awarding the subcontract, obtain rights in the
subcontractor's subject inventions.

                                N00178-03-C-1013                   Page 24 of 26
--------------------------------------------------------------------------------

         (2) The Contractor will include in all other subcontracts, regardless
of tier, for experimental, developmental, or research work the patent rights
clause required by Subpart 27.3.

         (3) In the case of subcontracts, at any tier, the agency,
subcontractor, and the Contractor agree that the mutual obligations of the
parties created by this clause constitute a contract between the subcontractor
and the Federal agency with respect to the matters covered by the clause;
provided, however, that nothing in this paragraph is intended to confer any
jurisdiction under the Contract Disputes Act in connection with proceedings
under paragraph (j) of this clause,

(h) Reporting on utilization of subject inventions. The Contractor agrees to
submit, on request, periodic reports no more frequently than annually on the
utilization of a subject invention or on efforts at obtaining such utilization
that are being made by the Contractor or its licensees or assignees, Such
reports shall include information regarding the status of development, date of
first commercial sale or use, grass royalties received by the Contractor, and
such other data and information as the agency may reasonably specify. The
Contractor also agrees to provide additional reports as may be requested by the
agency in connection with any march-in proceeding undertaken by the, agency in
accordance with paragraph (j) of this clause. As required by 35 U.S.C,
202(c)(5), the agency agrees it will not disclose such information to persons
outside the Government without permission of the Contractor.

(i) Preference for United States industry. Notwithstanding any other provision
of this clause, the Contractor agrees that neither it nor any assignee will
grant to any person the exclusive right to use or sell any subject invention in
the United States unless such person agrees that any product embodying the
subject invention or produced through the use of the subject invention will be
manufactured substantially in the United States, However, in individual cases,
the requirement for such an agreement may be, waived by the Federal agency upon
a showing by the Contractor or its assignee that reasonable but unsuccesful
efforts have been made to grant licenses can similar terms to potential
licensees that would be likely to manufacture substantially in the United
States or that under the circumstances domestic manufacture is not commercially
feasible.

(j) March-in rights. The Contractor agrees that, with respect to any subject
invention in which it has acquired title, the Federal agency has the right in
accordance with the procedures in 37 CFR 401.6 and any supplemental regulations
of the agency to require the Contractor, an assignee or exclusive licensee of a
subject invention to grant a nonexclusive, partially exclusive, or exclusive
license in any field of use to a responsible applicant or applicants, upon terms
that are reasonable under the circumstances, and if the Contractor, assignee, or
exclusive licensee refuses such a request the Federal agency has the right to
grant such a license itself if the Federal agency determines that--

         (1) Such action is necessary because the Contractor or assignee has not
taken, or is not expected to take within a reasonable time, effective steps to
achieve practical application of the subject invention in such field of use;

         (2) Such action is necessary to alleviate health or safety needs which
are not reasonably

<PAGE>
                                N00178-03-C-1013                   Page 25 of 26
--------------------------------------------------------------------------------

satisfied by the Contractor, assignee, or their licensees;

         (3) Such action is necessary to meet requirements for public use
specified by Federal regulations and such requirements are not reasonably
satisfied by the Contractor, assignee, or licensees; or

         (4) Such action is necessary because the agreement required by
paragraph (i) of this clause has not been obtained or waived or because a
licensee of the exclusive right to use or sell any subject invention in the
United States is in breach of such agreement.

(k) Special provisions for contracts with nonprofit organizations. If the
Contractor is a nonprofit organization, it agrees that--

         (1) Rights to a subject invention in the United States may not be
assigned without the approval of the Federal agency, except where such
assignment is made to an organization which has as one of its primary functions
the management of inventions; provided, that such assignee will be subject to
the same provisions as the Contractor;

         (2) The Contractor will share royalties collected on a subject
invention with the inventor, including Federal employee co-inventors (when the
agency deems it appropriate) when the subject invention is assigned in
accordance with 35 U.S.C. 202(e) and 37 CFR 401.10;

         (3) The balance of any royalties or income earned by the Contractor
with respect to subject inventions, after payment of expenses (including
payments to inventors) incidental to the administration of subject inventions
will be utilized for the support of scientific research or education, and

         (4) It will make efforts that are reasonable under the circumstances to
attract licensees of subject inventions that are small business firms, and that
it will give a preference to a small business firm when licensing a subject
invention if the Contractor determines that the small business firm has a plan
or proposal for marketing the invention which, if executed, is equally as likely
to bring the invention to practical application as any plans or proposals from
applicants that are not small business firms; provided, that the Contractor is
also satisfied that the small business firm has the capability and resources to
carry out its plan or proposal. The decision whether to give a preference in any
specific case will be at the discretion of the contractor. However, the
Contractor agrees that the Secretary of Commerce may review the Contractor's
licensing program and decisions regarding small business applicants, and the
Contractor will negotiate changes to its licensing policies, procedures, or
practices with the Secretary of Commerce when the Secretary's review discloses
that the Contractor could take reasonable steps to more effectively implement
the requirements of this subparagraph (k)(4).

(1) Communications.

The contractor shall report inventions in accordance with DFARS 252.227-4039
incorporated by reference in this contract.

16. REMARKS

The 5 Page Phase II plan to be delivered 120 days after contract award is used
to gain a better understanding of what the SBIR contractor plans to accomplish
under a Phase II effort. This plan along with the Phase I final report will be
used to decide whether or not a full Phase II proposal will be requested.

The following should be used as a format for the 5 Page Phase II Plan:

1. The cover (which will not count as a page) should have the Proposal Title,
Principal Investigator, (with phone and E-mail), Phase I contract #, Phase I
award start and end dates, Indication of whether a Phase I option was awarded
under the current contract and the name of the Government Technical Monitor.

2. The body of plan you should include all of the following: a brief reference
of the relevant Phase I solicitation topic and technical objective, a detailed
description of the proposed Phase II objective, work plan, anticipated benefits,
transition plans, commercialization applications, any matching dollars that will
be applied to the Phase II effort, qualifications of key personnel, proposed
facilities/equipment, and estimated costs. The potential to transition the
technology into the Navy fleet is a critical evaluation criteria. Your detailed
plans describing how the technology will be transitioned along with your success
in transition past SBIR/STTR or other work will be included as part of this
evaluation.

3. You may include also include discussions of related work and the companies
ability to successful transition other efforts, but this will be included as
part of the 5 page limit.

4. You may attach letters of endorsement from within the DOD or private sector
which discuss the direct benefit of the technology to them and their intent of
follow on funding either during Phase II or under a Phase III award. Letters of
endorsement are strongly encouraged and are important to show a clear Navy need
for the technology and an indication from the transition partners that they are
on board and support the technology. Letters of endorsement will not be counted
towards your 5 page limit.

Block A and 5: Applies to all CLINS and sub-CLINS which reference CDRL A005.

                                STATEMENT OF WORK

1.0 SCOPE. This statement of work establishes the requirements for the
manufacture, operation, test and acceptance of the Shipboard Automatic Chemical
Agent Detector and Alarm (Shipboard ACADA, MK 27 MOD 0) hereinafter referred to
as Shipboard ACADA.

1.1 BACKGROUND. Shipboard ACADA is a man-portable point detection system used by
U.S Naval forces to detect and alarm for chemical-agent vapor contamination of
the air in interior and exterior spaces of the ship. It responds to nerve (G, V)
and blister (H) chemical warfare agents. The most important operational feature
of Shipboard ACADA is that it monitors the ship's interior ambient air in real
time and detects agents at low concentrations while ignoring the presence of
common Shipboard interferents. Audible and visual alarm occurs in less than 60
sec.

NOTICE OF RADIOACTIVE MATERIALS (JAN 1997) (FAR 52.223-7)

(a) The Contractor shall notify the Contracting Officer or designee, in writing,
7 days prior to the delivery of, or prior to completion of any servicing
required by this contract of, items containing either (1) radioactive material
requiring specific licensing under the regulations issued pursuant to the Atomic
Energy Act of 1954, as amended, as set forth in Title 10 of the Code of Federal
Regulations, in effect on the date of this contract, or (2) other radioactive
material not requiring specific licensing in which the specific activity is
greater than 0.002 microcuries per gram or the activity per item equals or
exceeds 0.01 microcuries. Such notice shall specify the part or parts of the
items which contain radioactive materials, a description of the materials, the
name and activity of the isotope, the manufacturer of the materials, and any
other information known to the Contractor which will put users of the items on
notice as to the hazards involved (OMB No. 9000-0107).

(b) If there has been no change affecting the quantity of activity, or the
characteristics and composition of the radioactive material from deliveries
under this contract or prior contracts, the Contractor may request that the
Contracting Officer or designee waive the notice requirement in paragraph (a) of
this clause. Any such request shall--
         (1) Be submitted in writing;
         (2) State that the quantity of activity, characteristics, and
composition of the radioactive material have not changed; and
         (3) Cite the contract number on which the prior notification was
submitted and the contracting office to which it was submitted.
(c) All items, parts, or subassemblies which contain radioactive materials in
which the specific activity is greater than 0.002 microcuries per gram or
activity per item equals or exceeds 0.01 microcuries, and all containers in
which such items, parts or subassemblies are delivered to the Government shall
be clearly marked and labeled as required by the latest revision of MIL-STD-129

VALUE ENGINEERING (FEB 2000) (FAR 52.248-1)

As prescribed in 48.201, insert the following clause:
(a) GENERAL. The Contractor is encouraged to develop, prepare, and submit value
engineering change proposals (VECP's) voluntarily. The Contractor shall share in
any net acquisition savings realized from accepted VECP's, in accordance with
the incentive sharing rates in paragraph (f) below.
(b) DEFINITIONS.

<PAGE>

                                                  N00164-01-0-0042 PAGE 34 OF 50

        "ACQUISITION SAVINGS, "as used in this clause, means savings resulting
        from the application of a VECP to contracts awarded by the same
        contracting office or its successor for essentially the same unit.
        Acquisition savings include --
        (1) Instant contract savings, which are the net cost reductions on this,
        the instant contract, and which are equal to the instant unit .cost
        reduction multiplied by the number of instant contract units affected by
        the VECP, less the Contractor's allowable development and implementation
        costs;
        (2) Concurrent contract savings, which are net reductions in the prices
        of other contracts that are definitized and ongoing at the time the VECP
        is accepted; and
        (3) Future contract savings, which are the product of the future unit
        cost reduction multiplied by the number of future contract units in the
        sharing base. On an instant contract, future contract savings include
        savings on increases in quantities after VECP acceptance that are due to
        contract modifications, exercise of options, additional orders, and
        funding of subsequent year requirements on a multiyear contract.
        "COLLATERAL COSTS," as used in this clause, means agency cost of
        operation, maintenance, logistic support, or Government-furnished
        property.
        "COLLATERAL SAVINGS," as used in this clause, means those measurable net
        reductions resulting from a VECP in the agency's overall projected
        collateral costs, exclusive of acquisition savings, whether or not the
        acquisition cost changes.
        "CONTRACTING OFFICE" includes any contracting office that the
        acquisition is transferred to, such as another branch of the agency or
        another agency's office that is performing a joint acquisition action.
        "CONTRACTOR'S DEVELOPMENT AND IMPLEMENTATION COSTS," as used in this
        clause, means those costs the Contractor incurs on a VECP specifically
        in developing, testing, preparing, and submitting the VECP, as well as
        those costs the Contractor incurs to make the contractual changes
        required by Government acceptance of a VECP.
       "FUTURE UNIT COST REDUCTION," as used in this clause, means the instant
       unit cost reduction adjusted as the Contracting Officer considers
       necessary for projected learning or changes in quantity during the
       sharing period. It is calculated at the time the VECP is accepted and
       applies either -
       (1) Throughout the sharing period, unless the Contracting Officer decides
       that recalculation is necessary because conditions are significantly
       different from those previously anticipated; or
       (2) To the calculation of a lump-sum payment, which cannot later be
       revised.
       "GOVERNMENT COSTS," as used in this clause, means those agency costs that
       result directly from developing and implementing the VECP, such as any
       net increases in the cost of testing, operations, maintenance, and
       logistics support. The term does not include the normal administrative
       costs of processing the VECP or any increase in this contract's cost or
       price resulting from negative instant contract savings.
       "INSTANT CONTRACT," as. used in this clause, means this contract, under
       which the VECP is submitted. It does not include increases in quantities
       after acceptance of the VECP that are due to contract modifications,
       exercise of options, or additional orders. If this is a multiyear
       contract, the term does not include quantities funded after VECP
       acceptance. If this contract is a fixed-price contract with prospective
       price redetermination, the term refers to the period for which firm
       prices have been established.

                                                  N00164-01-D-0042 PAGE 35 OF 50

         "INSTANT UNIT COST REDUCTION" means the amount of the decrease in unit
         cost of performance (without deducting any Contractor's development or
         implementation costs) resulting from using the VECP on this, the
         instant contract. If this is a service contract, the instant unit cost
         reduction is normally equal to the number of hours per line-item task
         saved by using the VECP on this contract, multiplied by the appropriate
         contract labor rate.
         "NEGATIVE INSTANT CONTRACT SAVINGS" means the increase in the cost or
         price of this contract when the acceptance of a VECP results in an
         excess of the Contractor's allowable development and implementation
         costs over the product of the instant unit cost reduction multiplied by
         the number of instant contract units affected.
         "NET ACQUISITION SAVINGS" means total acquisition savings, including
         instant, concurrent, and future contract savings, less Government
         costs.
         "SHARING BASE," as used in this clause, means the number of affected
         end items on contracts of the contracting office accepting the VECP.
         "SHARING PERIOD," as used in this-clause, means the period beginning
         with acceptance of the first unit incorporating the VECP and ending at
         a calendar date or event determined by the contracting officer for each
         VECP.
         "UNIT," as used in this clause, means the item or task to which the
         Contracting Officer and the Contractor agree the VECP applies.
         "Value engineering change proposal (VECP)" means a proposal that -
         (1) Requires a change to this, the instant contract, to implement; and
         (2) Results in reducing the overall projected cost to the agency
         without impairing essential functions or characteristics; provided,
         that it does not involve a change --
                 (i) in deliverable end item quantities only;
                 (ii)In research and development (R&D) end items or R&D test
                 quantities that is due solely to results of previous testing
                 under this contract; or
                 (iii) To the contract type only.
     (c) VECP PREPARATION. As a minimum, the Contractor shall include in each
     VECP the information described in subparagraphs (c)(1) through (8) below.
     If the proposed change is affected by contractually required configuration
     management or similar procedures, the instructions in those procedures
     relating to format, identification, and priority assignment shall govern
     VECP preparation. The VECP shall include the following:
        (1) A description of the difference between the existing contract
        requirement and the proposed requirement, the comparative advantages and
        disadvantages of each, a justification when an item's function or
        characteristics are being altered, the effect of the change on the end
        item's performance, and any pertinent objective test data.
        (2) A list and analysis of the contract requirements that must be
        changed if the VECP is accepted, including any suggested specification
        revisions.
        (3) identification of the unit to which the VECP applies.
        (4) A separate, detailed cost estimate for
               (i)the affected portions of the existing contract requirement and
               (ii) the VECP.
               The cost reduction associated with the VECP shall take into
               account the Contractor's allowable development and
               implementation costs, including any amount attributable to
               subcontracts under the Subcontracts paragraph of this clause,
               below.
        (5) A description and estimate of costs the Government may incur in
        implementing the VECP, such as test and evaluation and operating and
        support costs.

         (6) A prediction of any effects the proposed change would have on
         collateral costs to the agency.
         (7) A statement of the time by which a contract modification accepting
         the VECP must be issued in order to achieve the maximum cost reduction,
         noting any effect on the contract completion time or delivery schedule.
         (8) Identification of any previous submissions of the VECP, including
         the dates submitted, the agencies and contract numbers involved, and
         previous Government actions, if known.
(d) SUBMISSION. The Contractor shall submit VECP's to the Contracting Officer,
unless this contract states otherwise. If this contract is administered by other
than the contracting office, the Contractor shall submit a copy of the VECP
simultaneously to the Contracting Officer and to the Administrative Contracting
Officer.
(e) GOVERNMENT ACTION.
         (1) The Contracting Officer [will] notify the Contractor of the status
         of the VECP within 45 calendar days after the contracting office
         receives it. If additional time is required, the Contracting Officer
         [will] notify the Contractor within the 45-day period and provide the
         reason for the delay and the expected date of the decision. The
         Government will process VECP's expeditiously; however, it [will] not be
         liable for any delay in acting upon a VECP.
         (2) If the VECP is not accepted, the Contracting Officer [will] notify
         the Contractor in writing, explaining the reasons for rejection. The
         Contractor may withdraw any VECP, in whole or in part, at any time
         before it is accepted by the Government. The Contracting Officer may
         require that the Contractor provide written notification before
         undertaking significant expenditures for VECP effort. (3) Any VECP may
         be accepted, in whole or in part, by the Contracting Officer's award of
         a modification to this contract citing this clause and made either
         before or within a reasonable time after contract performance is
         completed. Until such a contract modification applies a VECP to this
         contract, the Contractor shall perform in accordance with the existing
         contract. The [ ] decision to accept or reject all or part of any VECP
         [is a unilateral decision made solely at the discretion of the
         Contracting Officer.]
(f) SHARING RATES. If a VECP is accepted, the Contractor shall share in net
acquisition savings according to the percentages shown in the table below. The
percentage paid the Contractor depends upon -
         (1) This contract's type (fixed-price, incentive, or
         cost-reimbursement);
         (2) The sharing arrangement specified in paragraph (a) above
         (incentive, program requirement, or a combination as delineated in the
         Schedule); and
         (3) The source of the savings (the instant contract, or concurrent and
         future contracts), as follows:

         (2) Same sharing arrangement as the contract's profit or fee adjustment
         formula.
         (3) The Contracting Officer may increase the Contractor's sharing rate
         to as high as 50 percent for each VECP.
(g)CALCULATING NET ACQUISITION SAVINGS.
         (1) Acquisition savings are realized when
                  (i) the cost or price is reduced on the instant contract,
                  (ii) reductions are negotiated in concurrent contracts,
                  (iii) future contracts are awarded, or
                  (iv) agreement is reached on a lump-sum payment for future
                  contract savings (see subparagraph (i)(4) below). Net
                  acquisition savings are first realized, and the Contractor
                  shall be paid a share, when Government costs and any negative
                  instant contract savings have been fully offset against
                  acquisition savings,
         (2) Except in incentive contracts, Government costs and any price or
         cost increases resulting from negative instant contract savings shall
         be offset against acquisition savings each time such savings are
         realized until they are fully offset. Then, the Contractor's share is
         calculated by multiplying net acquisition savings by the appropriate
         Contractor's percentage sharing rate (see paragraph (f) above).
         Additional Contractor shares of net acquisition savings shall be paid
         to the Contractor at the time realized.
         (3) If this is an incentive contract, recovery of Government costs on
         the instant contract shall be deferred and offset against concurrent
         and future contract savings. The Contractor shall share through the
         contract incentive structure in savings on the instant contract items
         affected. Any negative instant contract savings shall be added to the
         target cost or to the target price and ceiling price, and the amount
         shall be offset against concurrent and future contract savings.

         (4) If the Government does not receive and accept all items on which it
         paid the Contractor's share, the Contractor shall. reimburse the
         Government for the proportionate share of these payments.

(h) CONTRACT ADJUSTMENT. The modification accepting the VECP (or a subsequent
modification issued as soon as possible after any negotiations are completed)
shall --
         (1) Reduce the contract price or estimated cost by the amount of
         instant contract savings, unless this is an incentive contract;
         (2) When the amount of instant contract savings is negative, increase
         the contract price, target price and ceiling price, target cost, or
         estimated cost by that amount; .
         (3) Specify the Contractor's dollar share per unit on future contracts,
         or provide the lump-sum payment;
         (4) Specify the amount of any Government costs or negative instant
         contract savings to be offset in determining net acquisition savings
         realized from concurrent or future contract savings; and
         (5) Provide the Contractor's share of any net acquisition savings under
         the instant contract in accordance with the following:
                  (i) Fixed-price contracts - add to contract price.
                  (ii) Cost-reimbursement contracts - add to contract fee.
(i) CONCURRENT AND FUTURE CONTRACT SAVINGS.
         (1) Payments of the Contractor's share of concurrent and future
         contract savings shall be made by a modification to the instant
         contract in accordance with subparagraph (h)(5) above. For incentive
         contracts, shares shall be added as a separate firm-fixed-price line
         item on the instant contract. The Contractor shall maintain records
         adequate to identify the first delivered unit for 3 years after final
         payment under this contract.
         (2) The Contracting Officer shall calculate the Contractor's share of
         concurrent contract savings by --
                  (i)Subtracting from the reduction in price negotiated on the
                  concurrent contract any Government costs or negative instant
                  contract savings not yet offset; and
                  (ii) Multiplying the result by the Contractors sharing rate.
         (3) The Contracting Officer shall calculate the Contractor's share of
         future contract savings by --
                  (i) Multiplying the future unit cost reduction by the number
                  of future contract units scheduled for delivery during the
                  sharing period;
                  (ii) Subtracting any Government costs or negative instant
                  contract savings not yet offset; and
                  (iii) Multiplying the result by the Contractor's sharing rate.
         (4) When the Government wishes and the Contractor agrees, the
         Contractor's share of future contract savings may be paid in a single
         lump sum rather than in a series of payments over time as future
         contracts are awarded. Under this alternate procedure, the future
         contract savings may be calculated when the VECP is accepted, on the
         basis of the Contracting Officer's forecast of the number of units that
         will be delivered during the sharing period. The Contractor's share
         shall be included in a modification to this contract (see subparagraph
         (h)(3) above) and shall not be subject to subsequent adjustment.
         (5) Alternate no-cost settlement method. When, in accordance with
         subsection 48.104-4 of the Federal Acquisition Regulation, the
         Government and the Contractor mutually agree to use the no-cost
         settlement method, the following applies:
                  (i) The Contractor will keep all the savings on the instant
                  contract and on its concurrent contracts only.

<PAGE>

                                                  N00164-01-D-0042 PAGE 39 OF 50

                  (ii) The Government will keep all the savings resulting from
                  concurrent contracts placed on other sources, savings from all
                  future contracts, and all collateral savings.
(j) COLLATERAL SAVINGS. If a VECP is accepted, [the Contracting Officer will
increase] the instant contract amount[ ], as specified in paragraph (h)(5) of
this clause, by a rate from 20 to 100 percent, as determined by the Contracting
Officer, of any projected collateral savings determined to be realized in a
typical year of use after subtracting any Government costs not previously
offset. However, the Contractor's share of collateral savings [will] not exceed[
] the contract's firm-fixed-price, target price, target cost, or estimated cost,
at the time the VECP is accepted, or [ ] $100,000, whichever is greater. The
Contracting Officer [will] be the sole determiner of the amount of collateral
savings[ ].
(k) RELATIONSHIP TO OTHER INCENTIVES. Only those benefits of an accepted VECP
not rewardable under performance, design-to-cost (production unit cost,
operating and support costs, reliability and maintainability), or similar
incentives shall be rewarded under this clause. However, the targets of such
incentives affected by the VECP shall not be adjusted because of VECP
acceptance. If this contract specifies targets but provides no incentive to
surpass them, the value engineering sharing shall apply only to the amount of
achievement better than target.
(l) SUBCONTRACTS. The Contractor shall include an appropriate value engineering
clause in any subcontract of $100,000 or more and may include one in
subcontracts of lesser value. In calculating any adjustment in this contract's
price for instant contract savings (or negative instant contract savings), the
Contractor's allowable development and implementation costs shall include any
subcontractor's allowable development and implementation costs, and any value
engineering incentive payments to a subcontractor, clearly resulting from a VECP
accepted by the Government under this contract. The Contractor may choose any
arrangement for subcontractor value engineering incentive payments; provided,
that the payments shall not reduce the Government's share of concurrent or
future contract savings or collateral savings.
(m) DATA. The Contractor may restrict the Government's right to use any part of
a VECP or the supporting data by marking the following legend on the affected
parts:

These data, furnished under the Value Engineering clause of contract _________,
shall not be disclosed outside the Government or duplicated, used, or disclosed,
in whole or in part, for any purpose other than to evaluate a value engineering
change proposal submitted under the clause. This restriction does not limit the
Government's right to use information contained in these data if it has been
obtained or is otherwise available from the Contractor or from another source
without limitations.

If a VECP is accepted, the Contractor hereby grants the Government unlimited
rights in the VECP and supporting data, except that, with respect to data
qualifying and submitted as limited rights technical data, the Government shall
have the rights specified in the contract modification implementing the VECP and
shall appropriately mark the data. (The terms "unlimited rights" and "limited
rights" are defined in Part 27 of the Federal Acquisition Regulation.)

SECTION 8(a) DIRECT AWARD (JUN 1998) (252.219-7009)

         (a) This contract is issued as a direct award between the contracting
         office and the 8(a) Contractor pursuant to the Memorandum of
         Understanding dated May 6, 1998, between the Small Business
         Administration (SBA) and the Department of Defense. Accordingly, the
         SBA is not a party to this contract. SBA does retain responsibility for
         8(a) certification, for 8(a) eligibility determinations and related
         issues, and for providing counseling and assistance to the 8(a)
         Contractor under the 8(a) Program. The cognizant SBA district office
         is:
                                    BALTIMORE DISTRICT OFFICE
                                    CITY CRESCENT BLDG., 6TH FLOOR
                                    10 S HOWARD STREET
                                    BALTIMORE, MD 21201
         (b) The contracting office is responsible for administering the
         contract and for taking any action on behalf of the Government under
         the terms and conditions of the contract; provided that-the contracting
         office shall give advance notice to the SBA before it issues a final
         notice terminating performance, either in whole or in part, under the
         contract. The contracting office also shall coordinate with the SBA
         prior to processing any novation agreement. The contracting office may
         assign contract administration functions to a contract administration
         office.
         (c) The Contractor agrees that-
                  (1) It will notify the Contracting Officer, simultaneous with
                  its notification to the SBA (as required by SBA's 8(a)
                  regulations at 13 CFR 124.308), when the owner or owners upon
                  whom 8(a) eligibility is based plan to relinquish ownership or
                  control of the concern.
                  Consistent with Section 407 of Pub. L. 100-656, transfer of
                  ownership or control shall result in termination of the
                  contract for convenience, unless the SBA waives the
                  requirement for termination prior to the actual relinquishing
                  of ownership and control; and
                  (2) It will not subcontract the performance of any of the
                  requirements of this contract without the prior written
                  approval of the SBA and the Contracting Officer.

RIGHTS IN TECHNICAL DATA--NONCOMMERCIAL ITEMS (NOV 1995) (DFAR 252.227-7013
(Alt 1))

      (a) Definitions. As used in this clause:

            (1) "Computer data base" means a collection of data recorded in a
    form capable of being processed by a computer. The term does not include
    computer software.
            (2) "Computer program" means a set of instructions, rules, or
    routines recorded in a form that is capable of causing a computer to perform
    a specific operation or series of operations.
            (3) "Computer software" means computer programs, source code, source
    code listings, object code listings, design details, algorithms, processes,
    flow charts, formulae and related material that would enable the software to
    be reproduced, recreated, or recompiled. Computer software does not include
    computer data bases or computer software documentation.
            (4) "Computer software documentation" means owner's manuals, user's
    manuals, installation instructions, operating instructions, and other
    similar items, regardless of storage medium, that explain the capabilities
    of the computer software or provide instructions for using the software.
            (5) "Detailed manufacturing or process data" means technical data
    that describe the steps, sequences, and conditions of manufacturing,
    processing or assembly used by the manufacturer to produce an item or
    component or to perform a process.
            (6) "Developed" means that an item, component, or process exists and
    is workable. Thus, the item or component must have been constructed or the
    process practiced. Workability is generally established when the item,
    component, or process has been analyzed or tested sufficiently to
    :demonstrate to reasonable people skilled in the applicable art that there
    is a high probability that it will operate as intended. Whether, how much,
    and what type of analysis or testing is required to establish workability
    depends on the nature of the item, component, or process, and the state of
    the art. To be considered "developed," the item, component, or process need
    not be at the stage where it could be offered for sale or sold on the
    commercial market, nor must the item, component, or process be actually
    reduced to practice within the meaning of Title 35 of the United States
    Code.
            (7) "Developed exclusively at private expense" means development was
    accomplished entirely with costs charged to indirect cost pools, costs not
    allocated to a government contract, or any combination thereof.
                  (i) Private expense determinations should be made at the
         lowest practicable level.
                  (ii) Under fixed-price contracts, when total costs are greater
         than the firm-fixed-price or ceiling price of the contract, the
         additional development costs necessary to complete development shall
         not be considered when determining whether development was at
         government, private, or mixed expense.
            (8) "Developed exclusively with government funds" means development
    was not accomplished exclusively or partially at private expense.
            (9) "Developed with mixed funding" means development was
    accomplished partially with costs charged to indirect cost pools and/or
    costs not allocated to a government contract, and partially with costs
    charged directly to a government contract.
            (10) "Form, fit, and function data" means technical data that
    describes the required overall physical, functional, and performance
    characteristics (along with the qualification requirements, if applicable)
    of an item, component, or process to the extent necessary to permit
    identification of physically and functionally interchangeable items.

commercial purposes or authorize others to do so.
         (12) "Government purpose rights" means the rights to-
                  (i) Use, modify, reproduce, release, perform, display, or
disclose technical data within the Government without restriction; and
                  (ii) Release or disclose technical data outside the Government
and authorize persons to whom release or disclosure has been made to use,
modify, reproduce, release, perform, display, or disclose that data for United
States government purposes.
         (13) "Limited rights" means the rights to use, modify, reproduce,
release, perform, display, or disclose technical data, in whole or, in. part,
within the Government. The Government may not, without the written permission of
the party asserting limited rights, release or disclose the technical data
outside the Government, use the technical data for manufacture, or authorize the
technical data to be used by another party, except that the Government may
reproduce, release or disclose such data or authorize the use or reproduction of
the data by persons outside the Government if reproduction, release, disclosure,
or use is-
                  (i) Necessary for emergency repair and overhaul; or
                  (ii) A release or disclosure of technical data (other than
detailed manufacturing or process any data) to, or use of such data by, a
foreign government that is in the interest of the Government and is required for

data incidental to contract administration, such as financial and/or management
information.
         (15) "Unlimited rights" means rights to use, modify, reproduce,
perform, display, release, or disclose technical data in whole or in part, in
any manner, and for any purpose whatsoever, and to have or authorize others to
do so.
(b) Rights in technical data. The Contractor grants or shall obtain for the
Government the following royalty free, world-wide, nonexclusive, irrevocable
license rights in technical data other than computer software documentation (see
the Rights in Noncommercial Computer Software and Noncommercial Computer
Software Documentation clause of this contract for rights in computer software
documentation):
                  (1) Unlimited rights. The Government shall have unlimited
rights in technical data that are-
                  (i) Data pertaining to an item, component, or process which
has been or will be developed exclusively with Government funds;
                  (ii) Studies, analyses, test data, or similar data produced
for this contract, when the study, analysis, test, or similar work was specified

Contractor by the Government;
                  (vii) Otherwise publicly available or have been released or
disclosed by the Contractor or subcontractor without restrictions on further
use, release or disclosure, other than a release or disclosure resulting from
the sale, transfer, or other assignment of interest in the technical data to
another party or the sale or transfer of some or all of a business entity or its
assets to another party;
                  (viii) Data in which the Government has obtained unlimited
rights under another Government contractor as a result of negotiations; or

Government contract or subcontract thereunder, with-
                           (A) Government purpose license rights or limited
rights and the restrictive condition(s) has/have expired; or
                           (B) Government purpose rights and the Contractor's

         (4) When requested by the Contracting Officer, the Contractor shall
provide sufficient information to enable the Contracting Officer to evaluate the
Contractor's assertions. The Contracting Officer reserves the right to add the
Contractor's assertions to the Attachment and validate any listed assertion, at
a later date, in accordance with the procedures of the Validation of Restrictive
Markings on Technical Data clause of this contract.
(f) Marking requirements. The Contractor, and its subcontractors or suppliers,
may only assert restrictions on the Government's rights to use, modify,
reproduce, release, perform, display, or disclose technical data to be delivered
under this contract by marking the deliverable data subject to restriction.

restrictions are asserted. When only portions of a page of printed material are
subject to the asserted restrictions, such portions shall be identified by
circling, underscoring, with a note, or other appropriate identifier. Technical
data transmitted directly from one computer or computer terminal to another
shall contain a notice of asserted restrictions. Reproductions of technical data
or any portions thereof subject to asserted restrictions shall also reproduce
the asserted restrictions.

furnished to the Government with government purpose rights shall be marked as
follows:

                            GOVERNMENT PURPOSE RIGHTS

                Contractor Name
                Contractor Address
                Expiration Date

         The Government's rights to use, modify, reproduce, release, perform,
display, or disclose these technical data are restricted by paragraph (b)(2) of
the Rights in Technical Data-Noncommercial Items clause contained in the above
identified contract. No. restrictions apply after the expiration date shown
above. Any reproduction of technical data or portions thereof marked with this

         (3) Limited rights markings. Data delivered or otherwise furnished to
the Government with limited rights shall be marked with the following legend:

         The Government's rights to use, modify, reproduce, release, perform,
display, or disclose these technical data are restricted by paragraph (b)(3) of
the Rights in Technical Data--Noncommercial Items clause contained in the above
identified contract. Any reproduction of technical data or portions thereof
marked with this legend must also reproduce the markings. Any person, other than
the Government, who has been provided access to such data must promptly notify

         The Government's rights to use, modify, reproduce, release, perform,
display, or disclose these data are restricted by Contract No. ____ (Insert
contract number) ____, License No. ____ (Insert license identifier)____. Any
reproduction of technical data or portions thereof marked with this legend must
also reproduce the markings.

                                 (End of legend)

         (ii) For purposes of this clause, special licenses do not include
government purpose license " . rights acquired under a prior contract (see
paragraph (b)(5) of this clause).

         (5) Pre-existing data markings. If the terms of a prior contract or
license permitted the Contractor to restrict the Government's rights to use,
modify, reproduce, release, perform, display, or disclose technical data
deliverable under this contract, and those restrictions are still applicable,
the Contractor may mark such data with the appropriate restrictive legend for
which the data qualified under the prior contract or license. The marking
procedures in paragraph
(f)(1) of this clause shall be followed.
(g) Contractor procedures and records. Throughout performance of this contract,
the Contractor and its subcontractors or suppliers that deliver technical data

clause; and
         (2) Maintain records sufficient to justify the validity of any
restrictive markings on technical data delivered under this contract.
(h) Removal of unjustified and nonconforming markings.
         (1) Unjustified technical data markings. The rights and obligations of
the parties regarding the validation of restrictive markings on technical data
furnished or to be furnished under this contract are contained in the Validation
of Restrictive Markings on Technical Data clause of this contract.
Notwithstanding any provision of this contract concerning inspection and

or strike a marking if, in accordance with the procedures in the Validation of
Restrictive Markings on Technical Data clause of this contract, a restrictive
marking is determined to be unjustified.

         (2) Nonconforming technical data markings. A nonconforming marking is a
marking placed on technical data delivered or otherwise furnished to the
Government under this contract that is not in the format authorized by this
contract. Correction of nonconforming markings is not subject to the Validation
of Restrictive Markings on Technical Data clause of this contract. If the
Contracting Officer notifies the Contractor of a nonconforming marking and the
Contractor fails to remove or correct such marking within sixty (60) days, the
Government may ignore or, at the Contractor's expense, remove or correct any
nonconforming marking.

         (i) Relation to patents. Nothing contained in this clause shall imply a
license to the Government under any patent or be construed as affecting the
scope of any license or other right otherwise granted to the Government under
any patent.

(j) Limitation on charges for rights in technical data.
         (1) The Contractor shall not charge to this contract any cost,
including, but not limited to, license fees, royalties, or similar charges, for
rights in technical data to be delivered under this contract when-
                  (i) The Government has acquired, by any means, the same or
greater rights in the data; or
                  (ii) The data are available to the public without
restrictions.

         (2) The limitation in paragraph 0)(1) of this clause-
                  (i) Includes costs charged by a subcontractor or supplier, at
any tier, or costs incurred by the Contractor to acquire rights in subcontractor
or supplier technical data, if the subcontractor or supplier :-has been paid for
such rights under any other Government contract or under a license conveying the
rights to the Government; and
                  (ii) Does not include the reasonable costs of reproducing,
handling, or mailing the documents or other media in which the technical data
will be delivered.

(k) Applicability to subcontractors or suppliers.

         (1) The Contractor shall ensure that the rights afforded its
subcontractors and suppliers under 10 U.S.C. 2320, 10 U.S.C. 2321, and the
identification, assertion, and delivery processes of paragraph (e) of this
clause are recognized and protected.

         (2) Whenever any technical data for noncommercial items is to be
obtained from a subcontractor or supplier for delivery to the Government under
this contract, the Contractor shall use this same clause in the subcontract or
other contractual instrument, and require its subcontractors or suppliers to do
so, without alteration, except to identify the parties. No other clause shall be
used to enlarge or diminish the Government's, the Contractor's, or a higher-tier
subcontractor's or supplier's rights in a subcontractor's or supplier's
technical data.

         (3) Technical data required to be delivered by a subcontractor or
supplier shall normally be delivered to the next higher-tier contractor,
subcontractor, or supplier. However, when there is a requirement in the prime
contract for data which may be submitted with other than unlimited rights by a
subcontractor or supplier, then said subcontractor or supplier may fulfill its
requirement by submitting such data directly to the Government, rather than
through a higher-tier contractor, subcontractor, or supplier.

         (4) The Contractor and higher-tier subcontractors or suppliers shall
not use their power to award contracts as economic leverage to obtain rights in
technical data from their subcontractors or suppliers.

         (5) In no event shall the Contractor use its obligation to recognize
and protect subcontractor or supplier rights in technical data as an excuse for
failing to satisfy its contractual obligation to the Government.
                                (End of clause)

STANDARD COMMERCIAL WARRANTY (6001)

The contractor shall extend to the Government the full coverage of any standard
commercial warranty normally offered in a similar commercial sale, provided such
warranty is available at no additional cost to the Government. Acceptance of the
standard commercial warranty does not waive the Government's rights under the
"Inspection" clause-nor does it limit the Government's rights with regard to the
other terms and conditions of this contract. In the event of a conflict, the
terms and conditions of the contract shall take precedence over the standard
commercial warranty. The standard commercial warranty period shall begin upon
final acceptance of the applicable material and/or services listed in the
Schedule.

The contractor shall provide a copy of its standard commercial warranty (if
applicable) with its offer. The warranty covers a period of \ 6 \ months.

                  power up, place in search mode, run BITs (System, Scanner,
                  SEM, PA), and internal and external confidence checks.

         m.       Acceptance authority/authorities. NSWC Dahlgren (B56), JSLSCAD
                  Test Team.

C.1.2    Provide additional engineering and technical support to include:

         a.       Select a facility to conduct the test.

         b.       Prepare detailed test procedures for approval (CDRL 0009).

         c.       Determine proper test installation, and arrange JSLSCAD system
                  installation to the test barge. (mounts and brackets will be
                  provided by the Government)

         d.       Conduct an initial test with an instrumented dummy load (a non
                  operational unit consisting of all three components - SEM, PA,
                  and ODU) to determine mount shock attenuation characteristics
                  and determine if they should be acceptable for a production
                  unit. Three dummy load test shots shall be conducted, one at
                  14 +/- 2 Hz, one at 10 +/- 1 Hz, and one at 8 +/- 1 Hz. The PA
                  and ODU will be attached without the use of resilient mounts
                  to a structure that is tuned to 25 Hz. Instrumentation for the
                  dummy load shall consist of one velocity meter on the Floating
                  Shock Platform (FSP), one accelerometer on the Deck Simulation
                  Fixture (DSF), two accelerometers mounted near the PA and ODU,
                  three accelerometers on the top of the "tower" mounting
                  structure for the SEM, and three additional accelerometers
                  attached to the SEM.

         e.       Contingent on the results of the dummy load test, the PA and
                  ODU shall be attached with resilient mounts for the regular
                  test shots. To identify the needed mounts in this instance
                  and/or to possibly correct any deficiencies noted in the SEM
                  resilient mounts, up to three isolator analyses may be
                  required. The mounts will be provided by the Government. Work
                  on this effort shall not commence until the contractor is
                  notified by the COR and funding is provided.

         f.       Verify that the JSLSCAD is properly installed for the test.

<PAGE>

         g.       Ensure that the JSLSCAD is instrumented with one velocity
                  meter on the FSP, one accelerometer on the DSF, and up to
                  eight other accelerometers. (contingent upon results of dummy
                  testing). Work on this effort shall not commence until the
                  contractor is notified by the COR and funding is provided.

         h.       Coordinate and perform the test according the test plan
                  supplied by NSWC Dahlgren and test procedures approved by NSWC
                  Carderock. Due to specific requirements, the test must include
                  four shots at 14 +/- 2 Hz, two at 10 +/- 1 Hz, and two at 8
                  +/- 1 Hz.

         i.       After test completion, visually inspect and conduct
                  operational tests to confirm condition of system. Report any
                  abnormalities. (The Government will provide JSLSCAD system
                  operator training to the test operators).

         j.       Remove system from test barge and return it to B56 in its
                  shipping container, within 15 days of test completion.

                              SECURITY REQUIREMENTS

                               STATEMENT OF WORK
                               -----------------

C.1      JOINT CHEMICAL AGENT DETECTOR (JCAD) SHOCK TEST SUPPORT.

Paragraphs C.1 and C.2.1 of the contract require the contractor to provide test
plans, test reports, and the necessary facilities and services for the conduct
of environmental testing and evaluation in support of Chemical and Biological
Defense programs. The Chemical-Biological Defense Branch (B53) has a requirement
to conduct the heavyweight shock (barge) test as specified in MIL-S-901D for
deck-mounted equipment.

C.1.1 Provide engineering and technical support and perform the heavyweight
shock (barge) test described above. Pertinent MIL-S-901D paragraph 6.2 data is
as follows:

     a.  Shock Tests, H.I. (High Impact) Shipboard Machinery, Equipment, and
         Systems, Requirements for: MIL-S-901D (Navy); 17 March 1989.

     b.  N.A.

     c.  Shock Grade. Grade A

     d.  Equipment Class. Class II

     e.  Shock Test Type. Type A

     f. Equipment mounting. Deck mounted

     g. Equipment mounting plane aboard ship. Back

<PAGE>

     h. Equipment mounting orientation. Unrestricted as to orientation aboard
        ship

     i. Method of Mounting. Tactical configuration mounted to deck plate using
        Navy approved test shock mounts

     j. Method of simulating shipboard connections. Tactical configuration used
        for mechanical connections; electrical to be simulated

     k. Mode of equipment operation during test. Energized, per MILSTD 901D for
        Grade A shock classification.

     l. Shock test acceptance criteria and associated post-test functional
        testing and inspection requirements are to include powering up, placing
        in initialization (Warm-up and self-diagnostic) and operation modes
        noting warning and reporting functions (audible and visual) upload and
        query of data, noting results of BIT test, and confidence checks.

     m. Acceptance authority/authorities. NSWC Dahlgren (B56), JCAD Test Team.

C.1.2 Provide additional engineering and technical support to include:

     a. Use an isolator shock simulation program to perform an isolator analysis
        in order to predict the JCAD's shock mount performance under the most
        severe MIL-S-901D shock test conditions and identify the isolation
        system's natural frequency. Actual deck simulator input from previous 14
        Hertz and 8-Hertz tests should be used in the analysis. If available
        deck simulator input from previous 10-Hertz test should also be used.

     b. Review and proved input to existing shock test plan.

     c. Determine proper test installation, and arrange JCAD system installation
        to the test barge (mounts and brackets will not be provided by the
        Government).

     d. Verification that the JCAD is properly installed for the test.

     e. Ensure that the JCAD is properly instrumented for displacement and shock
        loading measurements using a tri-axial accelerometer. The accelerometer
        measurements should then be integrated to velocity, and position
        measurements.

     f. Coordinate and perform the test as a "piggyback' shock test with another
        test load.

     g. Selection of a facility to conduct the test and provide shock test
        fixtures for the JCAD Shock test. Shock test strikes must provide 14 +/-
        2 hertz input, 10 +/- 1 hertz input, and 8 +/- 1 hertz input to the JCAD
        shock mount to verify the isolation system's ability to attenuate
        transmitted shock to levels within the predicted shock tolerance levels
        of the JCAD.

     h. A total of 4 shots should be conducted at the 14 +/- 2 hertz input
        level, 2 shots at teh 10 +/- 1 hertz input level, and 2 shots at the 8
        +/- 1 hertz input level to the JCAD shock mount.

<PAGE>

     i. After test completion, visually inspect and conduct operational tests
        (as specified in paragraph C.1.1 subparagraph 1) to confirm condition of
        system. Report any abnormalities.

     j. Remove system from test barge and return it to B53 in its shipping
        container.

In performing this contract, the Contractor shall not use as a consultant or
employ (on either a full or part time basis) any active duty U.S. Government
personnel (civilian or military) without the prior written approval of the
Contracting Officer. Such approval may be given only in circumstances where it
is clear that no laws and no DoD or U.S. Government instructions, regulations,
or policies might possibly be contravened and no appearance of a conflict of
interest will result.

NONPAYMENT FOR ADDITIONAL WORK

Any additional supplies or services or a change to work specified herein which
may be performed by the Contractor, either of his own volition or at the
request of an individual other than a duly appointed Contracting Officer or
his/her designee, except as may be explicitly authorized in this contract, are

participation in total contractor pension costs. NSWCDD's participation shall be
based upon the ratio of pension expense absorbed by NSWCDD contracts to total
pension expense for the life of the plan. If the pension expense ratio cannot be
readily determined, then a surrogate, as determined by the Contracting Officer,
such as total sales or cost input, may be used as long as it achieves an
equitable result. The credit due to NSWCDD shall be payable in full immediately

14. DESCRIPTION OF AMENDMENT/MODIFICATION (Organization by UCF section headings,
     including solicitation/contract subject matter where feasible.)

This contract modification is issued to Incorporate Value Engineering Change
Proposal VECP 0044V. The maximum contract price is decreased by $80,280.30 by
the incorporation of VECP 0044V as detailed on page 2 herein. In addition, this
modification corrects an error on P00004, page 2: ECP NUMBER STRACADA 0030 was
incorporated as no cost impact. This is an error. The incorporation of ECP
STRACADA 0030 results in an maximum contract amount increase of $3,642.00, the
increase does not impact the unit price matrix found in the basic contract as
the price impact is limited to the initial order placed under DO 0001. This
modification incorporates the cost impact of incorporating ECP STRACADA 0030
omitted from P00004. The maximum total amount of the contract to implement both
changes results in a decrease of $76,638.30 FROM $38,948,376.16 to
$___________.

Except as provided herein, all terms and conditions referenced in Item 9A and
10A, as heretofore changed, remains unchanged and in full force and effect.

3. The revised statement of work in shown below. Changes from the original SOW
are highlighted.

C.1 JOINT CHEMICAL AGENT DETECTOR (JCAD) SHOCK TEST SUPPORT.

      Paragraphs C.1 and C.2.1 of the contract require the contractor to provide
      test plans, test reports, and the necessary facilities and services for
      the conduct of environmental testing and evaluation in support of Chemical
      and Biological Defense programs. The Chemical-Biological Defense Brand
      (B53) has a requirement to conduct the heavyweight shock (barge) test as
      specified in MIL-S-901D for deck-mounted equipment.

C.1.1 Provide engineering and technical support and perform the heavyweight
      shock (barge) test described above. Pertinent MIL-S-901D paragraph 6.2
      data is as follows:

          a. Shock Tests, H.I. (High Impact) Shipboard Machinery, Equipment,
             and Systems, Requirements for; MIL-S-901D (Navy); 17 March 1989.

          b. N.A.

          c. Shock Grade. Grade A

          d. Equipment Class. Class II

          e. Shock Test Type. Type A

<PAGE>

          f. Equipment mounting. Deck mounted

          g. Equipment mounting plane aboard ship. Back

          h. Equipment mounting orientation. Unrestricted as to orientation
             aboard ship

          i. Method of Mounting. Tactical configuration mounted to deck plate or
             structural bulkheads using Navy approved test shock mounts

          j. Method of simulating shipboard connections. Tactical configuration
             used for mechanical connections; electrical to be simulated

          k. Mode of equipment operation during test. Energized, per MILSTD 901D
             for Grade A shock classification.

          l. Shock test acceptance criteria and associated post-test functional
             testing and inspection requirements are to include powering up,
             placing in initialization (Warm-up and self-diagnostic) and
             operation modes, noting warning and reporting functions (audible
             and visual), upload and query of data, noting results of BIT test,
             and confidence checks.

          m. Acceptance authority/authorities. NSWC Dahlgren (B56), JCAD Test
             Team.

C.1.2 Provide additional engineering and technical support to include:

          a. Use an isolator shock simulation program to perform an isoloator
             analysis in order to predict the JCAD's shock mount performance
             under the most sever MIL-S-901D shock test conditions and identify
             the isolation system's natural frequency. Actual deck simulator
             input from previous 14 hertz and 8-hertz tests should be used in
             the analysis. If available deck simulator input from previous
             10-hertz test should also be used.

          b. Review and provide input to existing shock test plan.

          c. Determine proper test installation, and arrange installation of 2
             JCAD systems to the test barge. Two different models of shock
             mounts will be provided by NSWC Dahlgren (on efor each JCAD unit).

          d. Verify that the JCADs are properly installed for the test.

          e. Ensure that the JCADs are properly instrumented for displacement
             and shock loading measurements using three accelerometers on each
             JCAD unit (Vertical, Fore/Aft, and Athwarship). The accelerometer
             measurements should then be integrated to velocity, and position
             measurements.

          f. Coordinate and perform the test as a "piggyback" shock test with
             another test load.

          g. Select of a facility to conduct the test and provide shock test
             fixtures for the JCAD Shock test. Shock test strikes must provide
             14 +/- 2 hertz input, 10 +/- 1 hertz

<PAGE>
             input, and 8 +/- 1 hertz input to the JCAD shock mounts to verify
             the isolation systems' ability to attenuate transmitted shock to
             levels within the predicted shock tolerance levels of the JCAD.

          h. A total of 4 shots should be conducted at the 14 +/- 2 hertz input
             level, 2 shots at the 10 +/- 1 hertz input level, and 2 shots at
             the 8 +/- hertz input level to the JCAD shock mounts.

          i. After test completion, visually inspect and conduct operational
             tests (as specified in paragraph C.1.1 subparagraph l) to confirm
             condition of systems. Report any abnormalities.

          j. Remove systems from test barge and return them to B53 in their
             shipping containers.

                             SECURITY REQUIREMENTS
