               no key money has been paid for the Property, and no contributions

               lease shall not be a protected lease under the Tenant Protection
               Law; and

WHEREBY        the Lessor is interested in renting the Property from the Lessee,
               and the Lessee is interested in renting the Property to the
               Lessor, in a unprotected lease, under the terms set out in this

    where they shall specify the condition of the Property.

4.  The Lessee accepts and declares that the laws of the Tenant Protection Law
    do not protect the Lease covered by this Agreement, and that this law, or
    any similar ones will not protect him.

5.  The Property will be used only for managing the offices and as a development
    center of the Lessee. The Lessee may not change the purpose of the lease
    without express written agreement of the Lessor.

6.  The Lessee undertakes not to hold any movable property outside the Property,
    and to conduct his business without causing noise, pungent odors, air
    pollution or any other nuisance to the Lessor, the neighbors, or any other
    person in the building or it's vicinity, other than is reasonable in the
    normal purpose of the lease.

    manner, and furthermore undertakes to comply with all the laws, regulations,
    by-laws and rules that apply to the property and it's use, and not endanger

10. The Lessee is responsible for all damages occurring as a result of the
    Lessee's use of the property, and he will reimburse the Lessor for all
    expenses accrued in repairing these damages. To remove all doubt, the Lessee
    is not responsible for any damage that has not occurred as a result of his
    use of the Property.

11. The rent shall be 17 US$ per square meter, per month. The rent shall be in
    Shekels, and shall be set at the last published rate before the time for
    payment occurs, plus VAT. The rent shall be payable per month, each month in

    expenses, such as: municipal taxes, electricity, water, telephone,
    maintenance of the building and peripherals, and any other running expenses
    of the Property.

12. The Lessee is responsible for insuring his own property, and any third party
    that comes into contact with it, his employees and guests, against ant

14. At the end of the lease, as stated in section 3, the Lessee will vacate the
    Property, and return it to the Lessor clean and free from all chattels and
    people, in the condition it was received, except for all reasonable wear and
    tear, and any damages not the responsibility of the Lessee. For any delay in

    regular rent, and this without limiting any other or additional rights of
    the Lessor.

15. It is agreed that the Lessor may use the Property for his continuing needs,
    as long as he is not interfering with the Lessee's ongoing activities. The
    Lessee is not to receive any payment for this use.

16. This Agreement is the whole and only agreement between the party's regarding
    the subject matter, and cancels and other agreement,, either verbal or in
    writing, that has been made before. Any change in conditions must be a
    signed agreement.

    action, under this Agreement, will only be authorized if done by a signed
    document, and even then will only apply to the specific action stated, and
    will not harm the rights of the party to the Agreement to realize the right
    if there is a change or extension of the damage to it.

    deemed to have been given on the third working day from the date sent.
