                      THE FEDERAL AVIATION ADMINISTRATION
                       WILLIAM J. HUGHES TECHNICAL CENTER


This Cooperative Research and Development Agreement (CRDA), dated
______________________ is entered into by and between Rapiscan Security
Products, Inc. [RAPISCAN], and the United States of America, as represented by
the Federal Aviation Administration William J. Hughes Technical Center [FAA
Technical Center], located at the Atlantic City International Airport, New
Jersey.

                                 A. BACKGROUND
                                 -------------

The development of effective enhanced automated baggage screening systems is a
continuing effort at the Federal Aviation Administration (FAA) Technical Center.
The Aviation Security Research & Development Division has been examining the
potential of several technologies and is particularly interested in further
development of the X-ray measurement and analysis techniques currently under
development by Rapiscan.  The Rapiscan technology is unique and proprietary in
its particular scanning approach as well as in its image processing ability to
sort out the signatures of numerous objects within a typical piece of luggage
and then to identify to an operator whether a particular object constitutes a
threat (explosive).  The technology has been developed to the point where it is
approaching the capability to meet the detection and throughput requirements for
enhanced automated inspection of luggage at an airport.

                             B. OBJECTIVE AND PLAN
                             ---------------------

The intent of this CRDA is to assist Rapiscan to optimize its prototype enhanced
automated X-ray baggage screening system for use at airports.

party for any reason shall not affect the rights and obligations of the parties
accrued prior to the effective date of termination of this AGREEMENT.  No
termination of this AGREEMENT, however effectuated, shall release the parties
hereto from their rights, duties and obligations under Articles 3, 4, 6, 7, 8,
9, 10, 11, and 12.

13.5 Extensions.  Extensions of the term of this AGREEMENT may be made prior to

                 COOPERATIVE RESEARCH AND DEVELOPMENT AGREEMENT
                         FAA TECHNICAL CENTER/RAPISCAN

                           OBLIGATION OF THE PARTIES


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

BACKGROUND

The development of effective enhanced automated baggage screening systems is a
continuing effort at the Federal Aviation Administration (FAA) Technical Center.
The Aviation Security Research & Development Division has been examining the
potential of several technologies and is particularly interested in further
development of the X-ray measurement and analysis techniques currently under
development by Rapiscan.  The Rapiscan technology is unique and proprietary in
its particular scanning approach as well as in its image processing ability to
sort out the signatures of numerous objects within a typical piece of luggage
and then to identify to an operator whether a particular object constitutes a
threat (explosive).  The technology has been developed to the point where it is
approaching the capability to meet the detection and throughput requirements for
enhanced automated inspection of luggage at an airport.

OBJECTIVE AND PLAN

The intent of this CRDA is to assist Rapiscan to optimize its prototype enhanced
automated X-ray baggage screening system for use at airports.

EXPECTED RESULTS

As a result of this agreement, we anticipate that there will be progress toward
developing enhanced automated baggage screening systems that can more
effectively screen carry-on and checked passenger luggage at airports.

CONSTRAINTS

All information concerning system performance generated under this agreement
will be covered by the Classification Guide for FAA Explosives Detection Systems
Information and Data.  No classified information shall be generated or received
by Rapiscan unless site and personnel clearances are granted by the Defense
Investigative Service.  Participation in testing shall be restricted to those
personnel having the need to know and possessing the appropriate security
clearance.  However, participation of Rapiscan personnel is considered
essential.  FAA will attempt to conduct the tests in a fashion that will allow
the widest possible participation by Rapiscan personnel and consultants without
comprising classified

                                       16
<PAGE>

information.  Rapiscan will supply cleared personnel to participate in the
testing whenever possible.

All explosive materials used during testing shall be handled by trained
personnel.  FAA will have the responsibility for providing the explosives test
articles.  Storage, handling, and transportation shall be in compliance with
established safety procedures and shall be in compliance with local, state, FAA,
and Federal regulations.

All reports generated resulting from work covered by this CRDA shall be
consistent with both security procedures and non-disclosure agreements and are
releasable only with the approval of FAA and the Rapiscan technical contact.

2.0  OBLIGATIONS OF THE PARTIES
     --------------------------

     2.1  Obligations of the FAA Technical Center

FAA shall provide assistance in several areas of development.  These include:
collaboration with FAA scientists, engineers, consultants, and testing
personnel; use of laboratory facilities, including assistance in obtaining test
samples of explosives, detonators, and luggage; and coordination with airports
and Government agencies to facilitate obtaining performance data.  FAA will
provide test samples that include typical explosives in quantities used by
terrorists against civil aviation.  FAA will supply both clean actual passenger
bags and bags with explosives concealed in a manner consistent with known
terrorist threats.  FAA will test for Probability of Detection and False Alarm
rate as a function of weight and type of explosive.  The threat objects may be
either bulk or sheet explosives.  Additional threat objects may be added to
characterize system performance.  FAA will provide to Rapiscan information
consistent with security regulations so that system performance can be
optimized.

     2.2  Obligations of Rapiscan:

Under this agreement, Rapiscan shall furnish to the FAA one or more of its
prototype X-ray machines for testing and data collection at the Technical Center
or at appropriate sites, for times and duration that are mutually acceptable.
Rapiscan will provide to FAA information regarding system operation, system
design, and algorithm development.  Any information that is company proprietary
shall be so labeled and will be treated accordingly.  If testing of the Rapiscan
X-ray system is to be done either at the FAA Technical Center or at Los Angeles
Airport, Rapiscan will make the arrangements and pay for the shipping.  At sites
other than the above, the arrangements and cost of shipping will be negotiated
between Rapiscan and FAA.
