                           5.1      Sublessee's Rights: If Sublessor fails to
perform any act on its par to be performed by Sublessor hereunder, then

date of Sublessee's written notice to Sublessor identifying the failure, and
after the passage of any notice and cure periods, and subject to the terms of
the Master Lease, perform such act. All such sums paid, and all reasonable costs
and expenses of performing any such act, shall be payable promptly by Sublessor

                  6.       Deposit: Sublessee shall pay Sublessor a security

dealings with such agent, broker, salesman, or finder.

                  8.       Authority to Execute: Sublessee and Sublessor each
represent and warrant to the other that each person executing this Sublease on

                  10.      Intentionally Deleted

                  11.      As-Is:

                           11.1     No Warranties: Sublessor has made no
representations or warranties of any kind, whether express or implied, as to the
condition of the Premises, the Building, the Complex or any other property, or
the suitability of the Premises for Sublessee's activities. Sublessee
acknowledges that prior to signing this Sublease, it has had the opportunity


                                      -3-

<PAGE>

to inspect and research the Building and the Premises, and to contact the Master
Lessor in order to independently satisfy itself as to the condition of same,
including without limitation, the presence or absence of Hazardous Materials.
Sublessee enters and agrees to use the Premises at its own risk, "as is", and
subject to any defects (whether patent or latent, known or unknown). Sublessee
waives and disclaims all warranties with respect to the Premises and the
Building and the Complex, whether express or implied, and assumes the risk that
its inspections and inquiry of the Master Lessor did not reveal adverse or
unexpected conditions.

                  12.      Sublease and Assignment: Pursuant to the restrictions
of the Master Lease, Sublessee may not sublease or assign all or any portion of
this Sublease. Any such Sublease or assignment shall be null, void and of no
force or effect. Sublessor and Sublessee acknowledge that this prohibition on
subleasing and assignment is required specifically by Master Lessor. Sublessor
and Sublessee recognize the difficulties that such a prohibition by Master
Lessor could cause if Sublessee desires to consolidate or merge. Therefore, if:
there shall occur (1) any assignment, merger or consolidation or other
reorganization of or affecting Sublessee and if Sublessee is not the surviving
corporation; or (2) any involuntary assignment or sublease by reason of
corporate reorganization, assignment, merger, consolidation, or for any other
reason, then unless Master Lessor's and Sublessor's advance written consents are
obtained (which consents may be withheld at their sole discretions), then this
Sublease shall terminate on the occurrence of any of the foregoing events.

                  13.      Furniture: The Premises shall be delivered to
Sublessee with the assets listed on Exhibit "B" attached hereto. During the
Sublease Term, none of the assets listed on Exhibit "B" may be removed by
Sublessee from the Premises at any time and at the end of the term said assets
shall be delivered by Sublessee to Sublessor in the condition in which they were
delivered to Sublessee, reasonable wear and tear excepted.

                  14.      Surrender: Notwithstanding the incorporation of
Section 8 of the Master Lease, on expiration of the Term of this Sublease, or on
any other termination of this Sublease, Sublessee shall not be required to
remove any tenant improvements in or alterations to the Premises that were
installed in the Premises prior to the Commencement Date.

                  15.      Termination Payment. If Master Lessor and Sublessor
jointly and voluntarily elect to terminate the Master Lease and this Sublease as
described in Section 4.2, above, then as of the termination, then Sublessor
shall pay to Sublessee a termination payment equal to the unused rental as of
the date of termination. If the Master Lease is terminated by reason of
Sublessor's breach thereof, and if such breach is in no way related to or
connected with a breach of this Sublease by Sublessee, and if after Master Lease
termination the Master Lessor requires Sublessee to continue its tenancy under
this Sublease at the Basic Rent paid by Sublessor under the Master Lease, then
Sublessor shall pay to Master Lessor on a monthly basis, as and when due, the
difference between the Basic Rent under the Master Lease and the Base Rent under
this Sublease for the remaining term of this Sublease (or if earlier, its
termination for any reason).

the presiding tribunal. A party not entitled to recover costs shall not recover
attorney fees. No sum of attorney fees shall be included in any computation of
