To promote timely and effective contract administration, correspondence
submitted under this contract shall be subject to the following procedures
(except for invoices and deliverable items):

a.       All correspondence relative to this contract shall be addressed to the
         Contracting Officer, listed in Section G.1. Correspondence of a
         technical nature shall include an information copy addressed to the
         Contracting Officer's Technical Representative (COTR), TSA, STDO
         Herndon, Va., listed in Section G.1.

b.       Mail: The Contractor shall use discretion in the use of "express" or
         "overnight" mail. These premium services should be used sparingly and
         in situations where the regular U.S. mail system would not be adequate
         for the timely transfer of technical or contract related documentation.
         Use of electronic mail or facsimile (FAX) service is encouraged where
         appropriate.

G.7      TRAVEL COSTS

a.       Travel shall be reimbursed on a cost plus no fee basis, subject to
         Joint Federal Travel Regulations (JFTR) guidelines and any other
         limitations cited below.

         1.       The Government will reimburse the Contractor, up to amounts
                  allowed by the JFTR, for reasonable travel expenditures,
                  incurred in the performance of this contract. In maintaining a
                  policy of keeping travel costs `reasonable' in the performance
                  of this contract, the Contractor agrees to use a cost
                  effective approach and continuously pursue opportunities to
                  lower and contain travel costs using, where practical, group
                  rate arrangements, off-peak travel itineraries and other
                  similar travel cost containment methods. Further, the
                  Contractor agrees to effect procedures to ensure Government
                  reimbursable travel expenditures are only incurred when
                  absolutely necessary. To assist it in determining reasonable
                  travel cost objectives, as needed, the Contractor is
                  encouraged to contact the TSA travel office for general
                  guidance. Further, to mitigate the inherently higher rates
                  associated with urgent emergent travel, the Contractor agrees
                  to contact, reasonably in advance, the Contracting Officer for
                  assistance prior to executing such travel, unless documented
                  circumstances clearly indicate such advance contact was not
                  possible.

                                      G-5
<PAGE>
         2.       Incurred travel costs, listed below, will be disallowed for
                  Government reimbursement and considered as being expenditures
                  to be absorbed by the Contractor. Included are costs:

                  (i)      in excess of amounts allowed by the JFTR;

                  (ii)     within a Government installation, where Government
                           transportation is available;

                  (iii)    for personal convenience, including daily travel to
                           and from work;

                  (iv)     in the case of urgent emergent travel, in excess of
                           amounts allowed by the JFTR, due to the Contractor
                           not requesting Contracting Officer assistance
                           reasonably in advance except for justifiable and
                           documented circumstances which prevented such advance
                           contact from being possible; and

                  (v)      in the replacement of personnel, when such
                           replacement is accomplished for the Contractor's or
                           employee's convenience

         In the case of urgent emergent travel, if the Contracting Officer's
         assistance has been reasonably requested in advance, or if requested as
         soon as practical after commencement of travel and properly justified
         and documented, the Contracting Officer may authorize, on a
         case-by-case basis, reimbursement for amounts in excess of JFTR rates.
         The Contractor shall implement procedures to minimize urgent emergent
         travel. Any Contracting Officer decision regarding reimbursement of
         travel costs in excess of amounts allowed by JFTR, for urgent emergent
         travel, shall be a unilateral decision, not subject to dispute or any
         right contained in the contracts disputes clause of this contract.

         3.       Relocation and travel costs incident to relocation will only
                  be reimbursable by the Government if such costs are:

                  (i)      in conformance with existing company policy;

                  (ii)     represent the most cost effective approach among all
                           other potential alternatives; and

                  (iii)    are specifically authorized by the Contracting
                           Officer in advance of being incurred.

         If the Contractor anticipates relocation costs will be incurred, the
         Contractor must submit, to the Contracting Officer, reasonably in
         advance, a written request with detailed justification and a
         cost/benefit analysis of alternatives. The Contracting Officer shall
         make a unilateral decision, on the request, which will not be subject
         to dispute or any other recourse contained in this contract.

b.       The Agreements shall facilitate the exchange of data and information
         between the General Contractor and/or System Integration Contractor and
         the Contractor as reasonable and necessary for the successful
         integration and implementation of contract deliverables in Section B.

c.       As a minimum, the Agreements shall provide for the following:

         1.       As requested by the General Contractor and/or System
                  Integration Contractor, the Contractor shall provide the
                  General Contractor and/or System Integration Contractor all
                  necessary interface data for the successful integration and
                  implementation of the contract deliverables.

         2.       Concurrent with its submittal to the Government of each
                  proposed engineering change, the Contractor shall provide to
                  the General Contractor and/or System Integration Contractor
                  any interface data that the Contractor believes is changed or
                  impacted by the proposed engineering change. The Contractor
                  will communicate to the General Contractor and/or System

                  implementation of the contract effort with other systems or
                  subsystems. If an interface problem is proposed to be resolved
                  by a change in the contract specifications, the Contractor
                  shall do so as described in c.2 above.

         5.       Unless restricted by the Government, the General Contractor
                  and/or System Integration Contractor shall be permitted to
                  attend all meetings between the Contractor and the Government
                  pertaining to equipment integration issues or matters, and the
                  Contractor shall be permitted to attend all meetings between
                  the General Contractor and/or System Integration Contractor
                  and the Government pertaining to equipment integration issues.

         6.       As may be necessary to accomplish the purposes of the

                  time to time at the Contractor's facility with the General
                  Contractor and/or System Integration Contractor.

         7.       If requested by the TSA, the General Contractor and/or System
                  Integration Contractor shall be permitted to monitor all
                  acceptance testing by the Contractor in connection with this
                  contract which the Government has the right to witness and the
                  Contractor shall be permitted to monitor all testing by the
                  General Contractor and/or System Integration Contractor in
                  connection with the General Contractor and/or Systems
                  Integration Contract as it pertains to the equipment.

         8.       In accordance with paragraph (d) of this agreement, the
                  General Contractor and/or System Integration Contractor and
                  the Contractor shall agree on the procedures for the proper
                  protection of proprietary information owned by the Contractor
                  and disclosed to the General Contractor and/or System
                  Integration Contractor, and of proprietary information owned

                  or any other Contractor or subcontractor solely for the
                  performance of the General Contract and/or System Integration
                  Contract and execute an appropriate non-disclosure agreement.

         9.       For as long as InVision offers to maintain the EDS machines
                  sold or manufactured by InVision to the TSA or any Government
                  entity (the InVision machines) to a reasonable standard and at
                  a fair and reasonable price, InVision will have a perpetual
                  right to be the maintenance provider for all InVision

                  nonconformance does not adversely affect any of the following:

                  a)       Health or Safety.

                  b)       Performance.

                  c)       Interchangeability, reliability, or maintainability.

                  d)       Effective use or operation.

                  e)       Weight or appearance (when a factor).

         (2)      Major Nonconformance - A nonconformance, other than critical,
                  that is likely to result in failure, or to materially reduce
                  the usability of the supplies or services for their intended
                  purpose; and that cannot be completely eliminated by rework or
                  reduced to a minor nonconformance by repair and directly
                  affects items in subparagraph (1) a through e above. This may
                  also include a failure or refusal by the Contractor to repair
                  the supplies or services under the warranty.

         (3)      Critical Nonconformance - A nonconformance that is likely to
                  result in hazardous or unsafe conditions for individuals
                  using, maintaining, or depending upon the supplies or
                  services, or is likely to prevent performance of a vital
                  agency mission.

b.       If a piece of equipment purchased by the TSA is discovered to have any
         nonconformance, the Contractor must propose a fix to the TSA. At the
         discretion of the Contracting Officer, this fix can be, but is not
         limited to, a "swap out" with a new piece of equipment or extended
         warranty. The proposed fix must be at no additional cost to the TSA,
         it's Assignee, or agent.

c.       If a piece of equipment is found to have any major or critical
         nonconformance and the Contractor does not satisfactorily correct the
         nonconformance, the TSA must be compensated as follows:

         (1)      If the nonconformance is discovered in year 1 - complete
                  replacement

d.       If the major or critical nonconformance is so grievous as to affect the
         TSA's, Assignee's, or agent's ability to maintain security at the site
         where the subject equipment is located, the TSA, as determined by the
         Contracting Officer, may:

         (1)      Suspend all subsequent orders at no cost to the TSA;

         (2)      Cancel all subsequent orders at no cost to the TSA;

         (3)      Seek an equitable adjustment for the value of the
                  nonconforming equipment;

         (4)      Seek any remaining common law damages; or

         (5)      Terminate for default.

            or in the Contractor's cost properly allocable to, the performance
            of any part of this contract; and

      (2)   The Contractor asserts its right to an adjustment within 30 days
            after the end of the period of work stoppage; provided, that if the
            Contracting Officer decides the facts justify the action, the
            Contracting Officer may receive and act upon a proposal submitted at
            any time before final payment under this contract.

(c)   If a stop-work order is not canceled and the work covered by the order is
      terminated for the convenience of the Government, the Contracting Officer
      shall allow reasonable costs resulting from the stop-work order in
      arriving at the termination settlement.

(d)   If a stop-work order is not canceled and the work covered by the order is
      terminated for default, the Contracting Officer shall allow, by equitable
      adjustment or otherwise, reasonable costs resulting from the stop-work
      order.
