                  normal working hours as applicable within HOS, Inc. By signing
                  this letter,  you accept that the proper  performance  of your
                  responsibilities may require you to work outside and in excess
                  of the  normal  work-time  schedule  in  accordance  with your

Lay Off: At any time during the  agreement,  HOS, Inc may terminate the contract
with a prior  notice  of 90 days.  During  the  notice  period,  you will  still
continue working and performing services for the company. In addition,  you will

Any dispute arising during your assignment or at the end of it in respect of the
interpretation,  execution or termination  of the assignment  will be settled in
accordance with the laws, regulations and customs in the US.

SOCIAL SECURITY TAXES
Due to lack of Social  Security  Totalization  agreements,  social  security and
Medicare taxes will be deducted from the US paystub on a monthly basis. In order
to maintain  certain  rights in Israel,  you will need to pay the minimum social
security taxes due to the Israeli Social Security Tax Authorities.

INCOME TAXES:
During your  assignment,  you will be considered  as US resident,  subject to US
income taxes.  As such, you must file an income tax return on a yearly basis. We
advise you to consult  with a local US CPA to assist you in filing  your  taxes.
Tax returns are due on April 15th of the succeeding tax year.

Your tax status in Israel should be examined closely to determine  whether a tax
liability  exists in Israel  during your  assignment as a whole or only during a
portion of it.

GENERAL
The  Company's  personnel  policies  and  standards  of  business  apply to your
assignment,  unless a written exception is provided by a company  representative
authorized to make that exception.  Any action  undertaken by HOS, Inc or one of
its  representatives  on  your  behalf  or your  benefit,  any  payment  done or
instruction  given to you by HOS, Inc will be deemed to be performed in the name
and for the account of the company and shall under no circumstance be considered
an  indication of the  existence of link of  subordination  between HOS, Inc and
yourself.

This  assignment  permits you the  opportunity to gain valuable  global business
experience,  as well as to perform important work for the company. If you are in
agreement  with the  conditions  of your  assignment as outlined in this letter,
