                 the course of your work for us shall be our sole and exclusive
                 property, except as may otherwise be required as provided in
                 subparagraph (b) below.

       (b)       You understand that we have entered into, or from time to time
                 in the future may enter into, agreements with agencies of the
                 United States Government (including, but not limited to the

                 limitations on us with respect to inventions and patents which
                 may be acquired by us or which may be conceived or developed

                 inventions and patents which may be acquired by us or which
                 may be conceived or developed by consultants, employees and
                 others rendering services to us.  You agree to be bound by
                 all such obligations, restrictions and limitations applicable
                 to inventions conceived or developed by you in the course of,

                 and to take any and all further action which may be required
                 to discharge such obligations and to comply with such
                 restrictions and limitations.

8.     NATURE OF RELATIONSHIP

It is understood that in performing any services pursuant to this agreement,
you are acting as an independent contractor and not as an employee, agent or
representative of ours.  You shall not act as our agent or enter into any
agreements or incur any obligations on our behalf, or commit us in any other
manner, without our prior written consent.  You will be responsible for
reporting and paying any federal and state taxes owing on the consulting income
received.

You have been provided with a copy of the General Dynamics Standards of
Business Ethics and Conduct.  You have also been provided with copies of the
General Dynamics policies and procedures relating to accounting and expense
reporting and travel.  You agree to conduct your performance under this
consultant agreement in accordance with these Standards and policies.

You understand that there are restrictions established by federal law on
certain Retired Military Officers and former U.S. Government employees.  While
there are many restrictions, they can be briefly summarized into two
categories.  First, on particular matters in which the Company was a party, you
may not make any communications with, or appearances before, the government on
behalf of the Company at any time.  Second, you may not lobby the DOD for five
years after leaving DOD.  'Lobby' in this context means to communicate with, or
appear before, the DOD with intent to influence official action.  You further
understand that General Dynamics requires that you comply with these
restrictions, and expects you to decline any assignment which may cause you to
violate the restrictions or policy.

9.    SECURITY

You shall abide by all applicable security laws and regulations of the United
States of America and our organization and shall take or refrain from taking
any action which may be required for compliance therewith.

It is understood that a security clearance up to the level of Top Secret shall
be required to perform services requested under this agreement.  You will be
contacted by our Security Department concerning the execution of a 'Consultant
Security Certification' and further guided in submitting appropriate government
clearance forms to the Defense Investigative Service Clearance Office.

10.   ENTIRE AGREEMENT

This instrument contains the entire agreement between the parties with respect
to the consulting services to be rendered by you to us, and supersedes all
prior agreements, arrangements, and/or understandings between the parties
regarding the subject matter hereof.

If the foregoing clearly sets forth our understanding, will you please sign and
return to us the enclosed duplicate copy of this letter, which shall thereupon
constitute an agreement between us.


                                   Very truly yours,

                                   GENERAL DYNAMICS CORPORATION
