INVISION TECHNOLOGIES, INC.

CHANGE IN CONTROL EQUITY ACCELERATION PLAN

Section 1.    INTRODUCTION.

The InVision Technologies, Inc. Change in Control Equity Acceleration Plan (the "Plan") was established effective May 21, 2002. The purpose of the
Plan is (i) to provide members of the senior management group of InVision Technologies, Inc. certain accelerated vesting with respect to such individuals' stock options in the event of a
Change in Control (as hereinafter defined), and (ii) to provide individuals who are employed at the vice president level at InVision Technologies, Inc. certain accelerated vesting with
respect to such individuals' stock options in the event that such individuals are subject to qualifying employment terminations in connection with a Change in Control. This Plan shall supersede any
change in control plan, policy or practice regarding stock option vesting acceleration previously maintained by InVision Technologies, Inc.

Section 2.    DEFINITIONS.

For purposes of the Plan, the following terms are defined as follows:



1

---



2

Section 3.    ELIGIBILITY FOR BENEFITS.

(a)  General Rules.Subject to the requirement set forth in this Section, the Company will provide the benefits
described in Section 4(a) or 4(b) of the Plan, as applicable, to Eligible Employees. In order to be eligible to receive benefits under the Plan, an Eligible Employee must execute and provide to
the Company a general waiver and release in substantially the form attached hereto as Exhibit A, Exhibit B or Exhibit C, as appropriate, and such release must become effective in
accordance with its terms. The Company, in its sole discretion, may modify the form of the required release to comply with applicable state or federal law and shall determine the form of the required
release.

(b)Exceptions to Benefit Entitlement.In no event shall an
employee, whether or not otherwise an Eligible Employee, receive benefits under the Plan in any of the following circumstances, as determined by the Company in its sole discretion:



3

---



Section 4.    OPTION ACCELERATION.

(a)Senior Management Level.If an Eligible Employee is notified
by the Company in writing that he or she is a member of the senior management group of the Company for the purposes of this Plan, then, effective as of the date of the Change in Control, the Options
then held by such Eligible Employee shall become fully vested and exercisable, regardless of whether or not the Eligible Employee's employment with the Company terminates due to a Covered Termination.

(b)Vice President Level.If an Eligible Employee is notified by
the Company in writing that he or she is a vice president of the Company for the purposes of this Plan, and such Eligible Employee's employment with the Company terminates due to a Covered
Termination, then, effective as of the date of the Covered Termination, the Options then held by such Eligible Employee shall become fully vested and exercisable.

Section 5.    LIMITATION ON BENEFITS.

(a)  Parachute Payments.If the aggregate value of the accelerated Option vesting under Section 4 and any
other payments or benefits that the Eligible Employee would receive pursuant to a Change in Control from the Company or otherwise, including, but not limited to, any payments or benefits under any
employment or key employee agreements (collectively, "Payment"), would constitute a "parachute payment" within the meaning of Section 280G of the Code that is subject to the excise tax imposed
by Section 4999 of the Code (the "Excise Tax"), then such Payment shall be equal to the Reduced Amount.



4

---



Section 6.    RIGHT TO INTERPRET PLAN; AMENDMENT AND TERMINATION.

(a)  Exclusive Discretion.The Company shall have the exclusive discretion and authority to establish rules,
forms, and procedures for the administration of the Plan and to construe and interpret the Plan and to decide any and all questions of fact, interpretation, definition, computation or administration
arising in connection with the operation of the Plan, including, but not limited to, the eligibility to participate in the Plan and the acceleration of Option vesting pursuant to the Plan. The rules,
interpretations, computations and other actions of the Company shall be binding and conclusive on all persons.

(b)  Amendment or Termination.The Company reserves the right to amend or terminate this Plan or the benefits
provided hereunder at any time;provided, however,that no such amendment or termination shall occur following a Change in Control if such amendment or
termination would adversely affect the rights of any persons who were employed by the Company prior to the Change in Control. Any action amending or terminating the Plan shall be in writing and
executed by an individual duly appointed by the Board of Directors of the Company.

Section 7.    NO IMPLIED EMPLOYMENT CONTRACT.

The Plan shall not be deemed (i) to give any employee or other person any right to be retained in the employ of the Company or (ii) to interfere
with the right of the Company to discharge any employee or other person at any time, with or without cause, which right is hereby reserved.

Section 8.    CHOICE OF LAW.

The law of the State of California shall govern all questions concerning the construction, validity and interpretation of the Plan, without regard to such state's
conflict of laws rules.
