as to which Sublessee is in default or for any sum which Sublessor may expend
or may be required to expend by reason of Sublessee's default in respect of any

encumber the monies deposited herein as security, and neither Sublessor nor its
successors or assigns shall be bound by any such assignments, encumbrance,

1997 to September 1, 1998.

         SECTION 7.       ASSIGNMENT AND SUBLETTING.   During the term of this
Sublease, this Sublease shall not be sold, assigned, transferred or in any way
disposed of, whether by operation of law or otherwise, nor shall any part or

Sublessor, which may be withheld in Sublessor's sole discretion.

         SECTION 8.       PRIME LEASE.

         (a) A copy of the Prime Lease, has been examined by Sublessee and
             Sublessee acknowledges it is familiar with the terms thereof.
             This Sublease is subject and subordinate to such Prime Lease.
             Except as may be inconsistent, inapplicable or inappropriate with
             the terms hereof or as otherwise expressly provided herein, all
             the terms, covenants and conditions in the Prime Lease contained
             shall be applicable to this Sublease, and be deemed incorporated
             herein, with the same force and effect (unless the context of the
             Prime Lease otherwise requires) as if Sublessor were the
             "Landlord" under the Prime Lease and Sublessee were the "Tenant"
             under the Prime Lease and the Leased Premises was the "Premises"
             and as if reference therein to "Lease" meant this Sublease.

         (b) Without intending to recite or limit all the provisions of the
             Prime Lease (for example, the parties, rent, terms, premises and
             use and occupancy recited in the Prime Lease), which may be
             inconsistent with, or inapplicable to, this Sublease or as to
             which express provision is made in this Sublease, reference is
             hereby made to the following inconsistent or inapplicable
             provisions of the Prime Lease:





                                       3
<PAGE>   4
                 (i)   The following articles of the Lease are inapplicable:
                       Article 4, Section 8.06, Articles 22, 35, 39, and
                       Exhibit C.
                 (ii)  The term Landlord in Article 8 shall include Sublessor
                       and Landlord.
                 (iii) Any obligations of Landlord in Article 9 and Sections
                       11.02, 12.01 shall not include Sublessor.

         SECTION 9.       SUBLESSOR'S OBLIGATIONS.

         (a) Except as specifically provided herein, Sublessor will not furnish
             or bear the cost of any services or repairs of any kind, including
             repairs needed as a result of destruction or condemnation
             (hereinafter collectively "services") to Sublessee.  Sublessee
             will look solely to the Landlord for the providing and performance
             of all services, if any, and will not seek nor require Sublessor
             to provide or perform same, nor shall Sublessee make any claim
             upon Sublessor for any failure to perform such obligation of
             Landlord respecting such services.
         (b) Without limiting the generality of Section 9 (a) above, it is
             agreed that (i) Sublessor's obligations to Sublessee hereunder
             with respect to the Leased Premises shall be no greater than
             Landlord's obligations to Sublessor under the Prime Lease with
             respect thereto; (ii) Sublessor shall be required to perform its
             obligations to Sublessee hereunder with respect to the Leased
             Premises only to the extent that Landlord has performed its
             similar obligations to Sublessor under the Prime Lease with
             respect thereto; (iii) Sublessee shall have no greater rights
             against Sublessor hereunder with respect to the Leased Premises
             than Sublessor has against Landlord under the Prime Lease with
             respect thereto; and (iv) if Sublessee shall be entitled to
             recover damages from Sublessor for Sublessor's failure to perform
             its obligations to Sublessee hereunder with respect to the Leased
             Premises, it may so recover only to the extent that Sublessor has
             succeeded in recovering from Landlord for its failure to perform
             its similar obligations to Sublessor.

         (c) It is further agreed that, in the event and to the extent that the
             exercise of any of Sublessee's rights with respect to the Landlord
             requires notice or other action (including joinder in any action
             to be taken by Sublessee) on the part of Sublessor, Sublessor will
             upon reasonable notice from Sublessee take or join in such action
             at Sublessee's cost and expense.


         SECTION 10.      INDEMNIFICATION.   Sublessee shall neither do nor
permit anything to be done which would constitute a breach or violation of any
of the terms, covenants or conditions of the Prime Lease or which would cause
the Prime Lease to be terminated or forfeited by reason of any right of
termination or forfeiture reserved or vested in the Landlord, and Sublessee
shall indemnify and hold Sublessor harmless from and against all claims, loss,
expense or liability of any kind whatsoever (including reasonable counsel fees)
by reason of any breach or default on





                                      4
<PAGE>   5
the part of Sublessee of its obligations under this Section 10.

         SECTION 11.      DEFAULT.   In the event Sublessee shall default in
performing any of the terms of the Prime Lease and/or this Sublease, then
Sublessor shall have all the rights and remedies against Sublessee respecting
such default as would be available to Landlord under the Prime Lease.

         SECTION 12.      TERMINATION.   If for any reason the term of the
Prime Lease shall be terminated prior to the expiration date of this Sublease,
this Sublease shall thereupon be terminated, and Sublessor shall not be liable
to Sublessee by reason thereof.

         SECTION 13.      NOTICES.

         (a) Except as otherwise expressly provided in this Sublease, any
             bills, statements, notices, demands, requests or other
             communications given or required to be given under this Sublease
             shall be deemed sufficiently given or rendered if in writing, sent

             Sublessee or any agent or employee of Sublessee may be found, if
             mailed prior to Sublessee taking possession of the Leased Premises
             or subsequent to Sublessee's  vacating, deserting, abandoning or
             surrendering the Leased Premises, or (c) to such other address(es)
             or other parties as either Sublessor or Sublessee may designate as
             its new address(es) or other parties for such purpose by notice
             given to the other in accordance with the provisions of this
             Section 13.

         (b) The time limits, if any, set forth in the Prime Lease for the
             giving of any notice are, for the purpose of this Sublease,
             changed so that the time limits of Sublessor and Sublessee shall
             be three (3) days less than the number of days, if any, stated in
             any particular case in the Prime Lease.

         SECTION 14.      BROKER.   Sublessee warrants and represents to
Sublessor that it has dealt with no broker or finder with respect to the
subleasing of the Leased Premises other than Cushman & Wakefield, Inc. and
Synergy Realty Inc.  Sublessor agrees to be responsible for the payment of any
commissions or other amounts due to such parties on account of this Sublease
pursuant to separate agreement.  Sublessee agrees to indemnify and hold
Sublessor harmless from and against any and all loss, cost, claim, liability,
damage and expense (including, without limitation, reasonable attorneys' fees)
which Sublessor may incur or sustain in connection with any claim by any broker

may be asserted against Sublessor as a result of any conversations,
correspondence or other dealings between Sublessee and such broker or finder
relating to the Leased Premises.

         SECTION 15.      INSURANCE.

         (a) Sublessee shall obtain and keep in full force and effect during
             the term of this Sublease at its own cost and expense the
             insurance required in the Prime Lease, protecting Sublessor as an
             additional insured against any and all claims for personal injury,
             death or property damage occurring in, upon, adjacent to, or
             connected with the Leased Premises or any part thereof.  Sublessee
             shall pay all premiums and charges therefor and upon failure to do
             so, Sublessor may, but shall not be obligated to make such
             payments, and in such latter event, Sublessee agrees to pay the
             amount thereof to Sublessor on demand and said sum shall be and be
             deemed to be additional rent.  Sublessee will include in the
             policies for such insurance a provision to the effect that the
             same will be non-cancelable except upon 30 days advance written
             notice to Sublessor.  The original insurance policies or
             appropriate certificates shall be deposited with Sublessor
             together with any renewals, replacements or endorsements to the
             end that said insurance shall be in full force and effect for the
             benefit of Sublessor during the term of this Sublease.  In the
             event Sublessee shall fail to procure and place such insurance,
             Sublessor may, but shall not be obligated to, procure and place
             the same, in which event the amount of the premium paid shall be
             paid by Sublessee to Sublessor upon demand and such sum shall be
             and be deemed to be additional rent.

         (b) Sublessee agrees to include in any policy insuring against loss,
             damage or destruction by fire or other casualty to Sublessee's
             Property and business interest in the Leased Premises (business
             interruption insurance), a waiver of the insurer's right of
             subrogation against Sublessor.

         (c) Sublessee hereby releases Sublessor with respect to any claim
             which it might otherwise have against Sublessor for loss, damage
             or destruction with respect  and to the extent of its property
             (including rental value or business interruption) and for injury
             to its employees, agents and invitees, occurring during the term
             of this Sublease, unless due to the negligence of Sublessor or its
             agents.

         SECTION 16.      HAZARDOUS MATERIALS.

         (a)  Indemnification.
              (1)  Sublessee shall and does indemnify and hold harmless
              Sublessor from and against any and all loss, damage, expenses,
              fees, claims, costs, fines, penalties, and liabilities including,
              but not limited to, reasonable attorneys' fees and costs of
              litigation, arising out of or in any manner connected with the
              presence or release or threatened release of Hazardous Materials,
              as herein defined, caused by Sublessee, its agents, employees,
              contractors or invitees.

              (2)  Sublessee's indemnification of Sublessor pursuant to Section
              16.(a) of this Sublease shall extend to all liability, including
              all foreseeable and unforeseeable





                                       6
<PAGE>   7
              consequential damages, directly or indirectly arising out of the
              use, generation, storage, release or disposal of Hazardous
              Materials on or about the Prime Leased Premises by Sublessee, its
              agents, employees, contractors or invitees, including, without
              limitation, the cost of any required or necessary repair,
              cleanup, or detoxification and the preparation of any closure or
              other required plans, whether such action is required or
              necessary prior to or following the termination of this Sublease,
              to the full extent that such action is attributable, directly or
              indirectly, to the use, presence, generation, storage, release or
              disposal of Hazardous Materials by Sublessee, its agents,
              employees, contractors or invitees.  Neither the written consent
              by Sublessor to the use, generation, storage, or disposal of
              Hazardous Materials nor the strict compliance by Sublessee with
              all statutes, laws, ordinances, rules, regulations, and
              precautions pertaining to Hazardous Materials shall excuse
              Sublessee from Sublessee's obligation of indemnification, which
              shall survive the expiration or earlier termination of the
              Sublease.

         (b)  Compliance.
              (1)  Sublessee_shall strictly comply with all statutes, laws,
              ordinances, rules, regulations, and precautions now or hereafter
              mandated by any federal, state, local, or other governmental
              agency (collectively, "the Law") with respect to the use,
              generation, storage, or disposal of Hazardous Materials at the
              Leased Premises by Sublessee, its agents, employees, contractors
              or invitees.

              (2)  Sublessee shall not cause, or allow any agent, employee,
              contractor, or invitee of Sublessee to cause any Hazardous
              Materials to be used, generated, stored, or disposed of on or
              about the Leased Premises, except in compliance with the Law.

         (c)  Entry.  Sublessee shall allow Sublessor to enter upon the Leased
              Premises to perform any testing Sublessor desires.  The testing
              shall be done at Sublessor's sole expense.

         (d)  Definition.  As used herein, Hazardous Materials shall include,
              but not be limited to those substances defined as "hazardous

         Improvements (as defined in the Prime Lease) made by Sublessor have
