                                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.

contractor's performance. The contractor has thirty (30) days after the

Government from using the report.

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

all hazardous material identified in paragraph (b) of this clause. Data shall be
submitted in accordance with Federal Standard No. 313, whether or not the
apparently successful offeror is the actual manufacturer of these items. Failure
to submit the Material Safety Data Sheet prior to award may result in the
apparently successful offeror being considered nonresponsible and ineligible for
award.
(e) If, after award, there is a change in the composition of the item(s) or a
revision to Federal Standard No. 313, which renders incomplete or inaccurate the
data submitted under paragraph (d) of this clause, the Contractor shall promptly

other clause of this contract providing for rights in data.
         (3) The Government is not precluded from using similar or identical
data acquired from other sources.
                                (End of Clause)

(c) The Offeror shall list which hazardous material listed in the Hazardous
Material Identification and Material Safety Data clause of this contract will be
labeled in accordance with one of the Acts in paragraphs (b)(1) through (5) of

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
in effect on the date of the contract.
(d) This clause, including this paragraph (d), shall be inserted in all
subcontracts for radioactive materials meeting the criteria in paragraph (a) of
this clause.

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.

         "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:

         (1) The Contracting Officer may increase the Contractor's sharing rate
         to as high as 75 percent for each VECP.
         (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.

            (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.

    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.

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.


PERFORMANCE EVALUATION (6008)

contract resulting from this solicitation, in accordance with FAR 42.15. The
following performance rating factors will be utilized: Quality; Cost Control;
Timeliness of Performance; Business Relations; Customer Satisfaction.

                  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.

                               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.

(a) The Contractor agrees that a partial basis for award of this contract is the
list of key personnel proposed. Accordingly, the Contractor agrees to assign to
this contract those key persons whose resumes were submitted with the proposal
necessary to fulfill the requirements of the contract. No substitution shall be
made without prior notification to and concurrence of the Contracting Officer in
accordance with this requirement.

(b) The contractor agrees that during the first 120 days of performance no key
personnel substitutions will be permitted unless such substitutions are
necessitated by an individual's sudden illness, death, or termination of
employment. All proposed substitutions shall have qualifications equal to or
higher than the qualifications of the person to be replaced. The Contracting
Officer shall be notified in writing of any proposed substitution at least
forty-five (45) days, in advance of the proposed substitution. Such notification
shall include: (1) an explanation of the circumstances necessitating the
substitution; (2) a complete resume of the proposed substitute; (3) the hourly
rates of the incumbent and the proposed substitute; and (4) any other
information requested by the Contracting Officer to enable him/her to judge
whether or not the Contractor is maintaining the same high quality of personnel
that provided the partial basis for award.

(c) In the event a requirement to increase the specified level of effort for a
designated labor category, but not the overall level of effort of the contract,
occurs, the Contractor shall submit to the Contracting Officer a written request
for approval to add personnel to the designated labor category. The same
information as specified in paragraph (b) above is to be submitted with the
request.

(d) The Contracting Officer shall evaluate requests for changes in personnel and
promptly notify the Contractor, in writing, whether the request is approved or
disapproved.

contract without the prior written approval of the SBA and the Contracting
Officer.

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
