|Subject: |  | Letter of Understanding for International Employment

This letter confirms a mutual understanding of the terms and conditions
applying to your international employment between you (the Employee) and LCC
International, Inc. (the Company). Such employment may be subject to medical
clearances and is subject to securing a passport, foreign government clearance,
and your acceptance of the terms and conditions outlined in this letter. If
the terms are acceptable to you, please sign and return the attached copy of
the letter to Andrea Farrell of Human Resources.

Your point of origin for this assignment has been designated as McLean,
Virginia. Your host location has been designated as Australia.

The anticipated effective period for your international employment is from on
or about March 1, 2002 to March 1, 2005. It is anticipated that the assignment
will be for a period of approximately three years, depending on the project
duration; however, the actual duration of the assignment is dependent upon both
the time necessary for you to complete the required duties, as determined by
LCC, and the budget available to support these tasks. The length of the
assignment may be extended if mutually agreed upon by you and the Company, and
may also be shortened based upon the needs of the Company, at the Companys
sole discretion. In any event, changes to assignment length must be confirmed
in writing.

You will continue to be paid in the United States through your normal salary
account. US Social Security and other US benefit contributions will continue
to be deducted from your base salary.

The following is a description of the allowances provided to you in US Dollars
specific to the assignment:
