         3.       Beginning April 1, 2000, and continuing through March 31,
2005, the Tenant shall pay the Base Net Rent per the terms of this Clause.

Beginning as of April 1, 2003, and thereafter as of the first day of April of
each successive year of the Term Extension Period, the Base Net Rent shall be
adjusted by multiplying $21,965.00 by a factor, the denominator of which shall
be the "Consumers Price Index FOR All Urban Consumers" (1982-1984 = 100),
specifically for "All Items", relating to the United States published by the
Bureau of Labor Statistics for April, 2000, and the numerator of which shall be
the CPI for the month of the Term Extension Period in which the adjustments as
are required hereunder occur. In the event the compilation or publication, or
both, of the CPI is revised, discontinued, or transferred to any other
governmental department, bureau or agency, the Landlord may select a comparable,
alternative index for the purposes of the above adjustment.

         4.       Beginning April 1, 2000, and continuing through the end of the
Term Extension Period on March 21, 2005, the Tenant shall pay the Additional
Rent as set forth above for the Term Extension Period.

         5.       The Landlord grants the Tenant an option to extend the Term of
the Lease for the Premises for an additional five (5) year extension period. To
exercise this option, the Tenant must strictly comply with the following
conditions: (a) be in strict compliance with all of its obligations under the
terms of the Prior Agreements on the date of exercising this option and on the
date of the beginning of the extension period, and (b) give written notice to
the Landlord no later than twelve (12) months in advance of the beginning of the
extension period, indicating the Tenant's unequivocal and unconditional
intention to exercise this option. If the Tenant does not strictly comply with
the aforesaid conditions, then the Tenant shall not have exercised this option.
If either party rightfully terminates the Lease, or if the notice deadline
passes before the Tenant exercises this option, then this option shall
automatically and immediately be void and shall have no further effect.

If the Tenant exercises this option to extend the Term, then the extension
period shall begin on April 1, 2005, and shall end on March 31, 2010. The
monthly base rent for the extension period shall be determined per the terms of
this Clause.

Beginning as of April 1, 2005, and thereafter as of the first day of April of
each successive year of the Term Extension Period, the Base Net Rent shall be
adjusted by multiplying $21,965.00 by a factor, the denominator of which shall
be the "Consumers Price Index for All Urban Consumers" (1982-1984 = 100),
specifically for "All Items", relating to the United States published by the
Bureau of Labor Statistics for April, 2000, and the numerator of which shall be
the CPI for the month of the Term Extension Period in which the adjustments as
are required hereunder occur. In the event the compilation or publications, or
both, of the CPI is revised, discontinued, or transferred to any other
governmental department, bureau agency, the Landlord may select a comparable,
alternative index for the purposes of the above adjustment.

During the extension period, the Landlord and the Tenant shall comply with all
of the terms of the Lease and any supplemental agreements, in effect, except
that the terms related to base net rent and the Term of the Lease shall be
deemed to be amended to be consistent with the exercise of this option.

any broker in connection with this Term Extension Agreement.

         7.       Tenant shall have the exclusive right to use all of the
parking spaces located on Lot 5C. Block 390, having an address of 6 Hollywood

         8.       All of the other terms of the Prior Agreements shall remain in
effect, except as specifically amended herein.

         9.       This Agreement binds the Landlord and all parties which
rightfully succeed to its rights or take its place. This Agreement binds the
Tenant and all parties which rightfully succeed to its rights or take its place
with the Landlord's consent in accordance with the terms of the Lease.
