                         1.  ADDITIONAL PREMISES
                             -------------------

     In order for Lessor to induce Lessee to continue under the terms of
the Lease, the Lessor hereby demises and leases to Lessee an additional
1,000 square feet of rentable space ("Additional Space") adjacent to the
Space presently leased to Lessee in the Building to be used by Lessee as
offices.

                             2.  TERM
                                 ----

     Lessor represents that said Additional Space shall be ready and
available Site Prepared as provided in Section 3 of the Lease for Lessee's
Use on or before but no later then December 1, 1997, otherwise Lessee shall
have the option, at its sole discretion, to terminate the Lease and the
Addendum and recover any and all sums as provided for in Section 3 of the
Lease including renovations; Section 3 of the Lease shall apply to the
Additional Space, and the term for the Additional Space will commence on
the Commencement Date as defined in Section 3 of the Lease.

                             3.  RENT
                                 ----

     Lessor hereby provides Lessee with free rent for the Additional Space
for the first 19 months from the Commencement Date ("Free Rent Period);
and thereafter, Lessee agrees to pay Lessor for the Additional Space the
same per square foot rental, to wit $9.50 per square foot, as is requiring
for the Space as per Section 4 of the Lease.

     During the Free Rent Period and through the remainder of the Term of
the Lease the Additional Space shall be added to Lessee's Proportionate
Share as such relates to additional rent as provided in Section 4 of the
Lease.

                         4.  OTHER TERMS
                             -----------

     All capitalized terms shall have the meaning and definitions as
provided in the Lease, except for the capitalized terms as clarified in
this Addendum; provided however, the term Space as defined in Section 1
of the Lease (presently defined as 4,000 square feet of rentable space)
shall be defined to include the actual rentable space as determined by
specific measurements of Lessor and Lessee in the immediate future, and
based upon such, the base rent as now presented in Section 4 of the Lease
will be adjusted to reflect the new and specific definition of Space as
provided herein, it being understood that the square foot rent shall
remain at $9.50 per square foot.

     For purposes of the Lease, other than as provided for in this
Addendum, the term Space shall include the Additional Space.

     Other than pursuant to this Addendum, the Lease shall otherwise
remain in full force and effect in accordance with its terms.
