  • Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.

     termination of the lease, Tenant may remove any or all such alterations,
     additions or installations in such a manner as will not substantially
     injure the leased premises. In the event Tenant shall elect to make any
     such removal, Tenant shall restore the premises, or the portion or
     portions affected by such removal, to the same condition as existed prior
     to the making of such alteration, addition or installation, ordinary wear
     and tear, excepted.

     All alterations, additions or installations not so removed by Tenant shall

9.   If during the term of this lease:

          a.   The building or the premises shall be damaged or destroyed by
          fire or other casualty to such extent that in the judgment of Landlord
          such damage or destruction cannot be restored or repaired with
          reasonable diligence within 90 days from the happening of such damage
                                      --

          the other within 60 days from the happening of such damage or
          destruction to terminate this lease, and if the premises shall have
          been rendered wholly untenantable by such fire or other casualty, such
          termination shall be effective as of the date of such notice; but if
          the premises shall not have been rendered wholly untenantable, Tenant
          shall retain such portions of the premises for such periods not
          exceeding 90 days after such notice of termination shall have been
          given and in that event the date of termination of this lease shall be
          the date upon which Tenant shall vacate the last portion of the
          premises.

          b.   If the building or the premises shall be damaged by fire or other
          casualty, but not to such extent that Landlord determines that such
          damage cannot be repaired with reasonable diligence within 90 days, or
                                                                     -- 
          if the building or the premises shall be damaged to a greater extent,
          but neither party shall elect to terminate this lease in accordance
          with the preceding subparagraph hereof, then Landlord shall proceed
          diligently to fully restore and repair all such damage to the building
          and the premises.

          c.   If the utility of the premises to Tenant shall be materially
          diminished by reason of the existence of damage to the building or the
          premises by reason of fire or other casualty, regardless of whether
          the premises shall have been rendered wholly or partially untenantable
          by reason of the existence of such damage, both the basic rent and
          additional rent otherwise becoming due hereunder shall be abated in
          proportion to the diminution of the amount of floor space available to
          Tenant. Upon termination of this lease by reason of a fire or other
          casualty, any rent which shall at such time have been paid but not
          earned shall be refunded to Tenant.

     performed by this lease including a default by Tenant in payment of the
     rent as herein specified, or any part thereof, the Landlord shall have the
     right to re-enter said premises, to remove the Tenant and all persons
     holding under the lease therefrom, and to terminate this lease and
     repossess the premises; provided, however, that such repossession shall not
     constitute a waiver by the Landlord of any other rights which Landlord
     might have to enforce collection of rents for the balance of the term or to
     recover damages from the Tenant for default in payment of rents.

                                 CONDEMNATION

     12.  In the event that the leased premises shall be taken for public use by

     having the power of eminent domain, then this lease shall terminate as of
     the date on which possession thereof shall be taken for such public use,
     or, at the option of Tenant, as of the date on which the premises shall
     become unsuitable for Tenant's regular business by reason of such taking;
     provided, however, that if only a part of the leased premises shall be so
     taken, such termination shall be at the option of Tenant only. If such a
     taking of only a part of the leased premises occurs, and Tenant elects not

     rent than is called for in this lease, the Landlord and Tenant shall share
     equally in the excess rent, after Tenant recoups its subleasing costs,
     including but not limited to: broker's fees, attorneys' fees, reasonable
     improvements required for the subtenant and other reasonable and necessary
     out-of-pocket costs.

     Tenant shall be able to assign or sublease part of all of the premises
     without Landlord's consent to any affiliates by serving Landlord 60 day
     advance written notice of its intention to do so. Affiliates would include
     any corporation, partnership or other entity that controls, is controlled

     entity resulting from the merger or consolidations with Tenant or to any
     entity that acquires all of Tenant's assets as a going concern of the
     business that is being conducted on the premises, as long as the assignee
     or Subtenant is a bona fide entity and assumes the obligations of the
     Tenant.

Tenant. The Tenant shall furnish a certificate or duplicate policy of such
coverage to the Landlord, and such insurance shall contain provisions preventing
cancellations, discontinuance or alteration without at least 10 days prior
notice to the Landlord.

contain a provision that the Tenant's waiver of subrogation rights against the
Landlord and any other co-insured, which subrogation rights the Tenant hereby
waives, shall not invalidate such coverage. Landlord shall also waive any
subrogation rights which Landlord or Landlord's insurers may have against the
Tenant if such waivers arc permitted by such insurers, and any and all public
liability insurance insuring the Landlord shall also contain a provision that
the Landlord waives subrogation rights against the Tenant should such provisions
be obtainable from the insurer.

occupant of the premises or the building, or any other person occurring in or
about the building or the premises resulting directly, or indirectly from any
existing or future condition, defect, matter or thing in the premises, the
building or part of it or from equipment or appurtenance becoming out of repair
or from accident, or from any occurrence, act, or from negligence or omission of
any tenant or occupant of the building, or of any other person. This paragraph
shall apply especially, but not exclusively, to damage caused as aforesaid or by
the flooding of lower floors or other sub-surface areas or by refrigerators,
sprinkling devices, air-conditioning apparatus, water, snow, frost, steam,
excessive heat or cold, falling plaster, broken glass, sewage, gas, odors or
noise, or the bursting or leaking of pipes or plumbing fixtures, and shall apply
equally whether any such damage be caused or result from any thing or
circumstance above mentioned, or any other thing or circumstance whether of a
like or wholly different nature. If any such damage to the premises or to the
building, or to tenants thereof, results from any act or omission of negligence
of the Tenant or Tenant's agents, employees or invitees, the Landlord may, at
the Landlord's option, repair such damage and the Tenant shall, upon demand by
the Landlord, reimburse the Landlord forthwith for all costs of such repairs and
damages both to the building and to die tenants thereof, in excess of the
amounts, if any, paid to Landlord under insurance covering such damages. All
property entrusted to the Landlord or any of its agents or employees, and all
property in the building or in the premises belonging to the Tenant, its agents,
employees or invitees, or to any occupant of the premises shall be there at the
risk of the Tenant or other person only, and the Landlord shall not be liable
for damage thereto or theft, misappropriation or loss thereof. The Tenant agrees

                      LANDLORD'S RIGHT TO ENTER PREMISES
                      ----------------------------------  
                    
14.  Tenant shall permit Landlord and Landlord's agents to enter at all
reasonable times to view the state and condition of the premises or to make such
alterations or repairs therein as may be necessary for the safety and
preservation thereof, or for any other reasonable purposes. Tenant shall also
permit Landlord or Landlord's agents, on or after 180 days preceding the
expiration of the term of this lease, to show the premises to prospective
tenants at reasonable times, and to place notices on the front of said premises,
or on any part thereof, offering the premises for lease.

If the Tenant shall abandon or vacate said premises before the end of the term
of this lease, or shall suffer the rent to be in arrears, the Landlord may, at
its option, forthwith cancel this lease or it may enter said premises as the
agent of the Tenant, by force or otherwise, without being liable in any way
therefor, and re-let the premises with or without any furniture that may be
therein, as the agent of the Tenant, at such price and upon such terms and for
such duration of time as the Landlord may determine, and receive the rent
therefor, applying the same to the payment of the rent due by these presents,
and if the full rental herein provided shall not be realized by Landlord over
and above the expenses to Landlord in such reletting, the said Tenant shall pay
any deficiency, and if more than the full rental is realized, Landlord will pay
over to said Tenant the excess of demand.

                              CONSTRUCTION LIENS
                              ------------------

15.  The Tenant shall promptly pay for any work done in or about the premises
contracted by it, and will not permit or suffer any construction liens to attach
to the premises as a result thereof, furnishing Landlord with lien waivers, and
shall promptly cause any claim for any such lien to be released, or to secure
the Landlord to Landlord's satisfaction in the event the Tenant desires to
contest any such claim.

                             DEFAULT AND REMEDIES
                             --------------------        
               
16.  a.   Acts of Default: Each of the following shall be deemed a default by
     the Tenant and a breach of this lease:

          1. Failure to pay any of the rent or additional rent herein reserved,
          or any part thereof, for a period of 15 days after written notice; or

          2. Failure to do, observe, keep and perform any term, covenant,
          condition, agreement or provision in this lease to be done, observed,
          kept and performed by the Tenant (except concerning the payment of
          rent or additional rent) for a period of 30 days after written notice;
          or

          3. The abandonment of the leased premises by the Tenant; or

          4. Use or permit to be used the premises or any part thereof for any
          purpose other than

                                     Page 7
<PAGE>
 
          above specified without the written consent of the Landlord; or

          5.   Suffer or permit the entry in any involuntary proceedings brought
          against Tenant in any court or tribunal under any section of any
          bankruptcy act of any order adjudicating Tenant to be insolvent or
          unable to pay Tenant's debts unless such order is vacated within 30
          days after its entry; or

          6.   File any voluntary petition or similar proceedings in any court
          or tribunal under any section of any bankruptcy act to delay or reduce
          or modify Tenant's debts or obligations; or

          7.   Be declared insolvent according to law, or make, suffer or permit
          any assignment of Tenant's property for the benefit of creditors or
          the appointment of any receiver or trustee for Tenant or Tenant's
          property.

       b. Remedies: Upon the happening of any of the acts of default set forth
          above, which acts remain uncured after expiration of the time periods
          provided for above, the Landlord shall have the right to elect any one
          or more of such remedies as may be allowed by applicable law.

       c. In the event of default, Landlord may, but shall not be obligated to,
          remedy such default and in connection therewith pay the costs and
          expenses occasioned by such default and employ counsel with respect
          thereto. All reasonable sums expended or reasonable obligations
          incurred by Landlord in connection with the cure of any such default
          shall be paid by Tenant upon demand.

       d. The respective rights of the Landlord and Tenant pursuant hereto shall
          be in addition to such as they might otherwise have pursuant to law
          and cumulative; and the exercise by either party of any particular
          right or remedy in relation to any such breach shall not be deemed to
          be a waiver of any other rights or remedies. A waiver by either party
          of any breach or breaches by the other of any one or more of the
          terms, covenants or conditions contained in this lease shall not
          constitute a waiver of any rights or remedies of such party for any
          other or subsequent breach.

       e. Unless the same be expressed in writing signed by the Landlord, the
          Landlord shall not be deemed to have accepted any surrender of the
          premises, nor to have prejudiced any right of the Landlord under this
          lease by any action in reference to the same or to the premises or the
          possession thereof, nor to have terminated, continued or extended this
          lease by advertising the premises for rent or by caring for the same
          or submitting the same to inspection of any person or by receiving
          from the Tenant any money or keys or by any other action.

                                 ATTORNEY FEES
                                 -------------

17. In case the Tenant makes default in the performance of any of the terms,
covenants, agreements or conditions contained in this lease and the Landlord
therefore places the enforcement of this lease, or any part thereof, or the
collection of any rent due, or to become due hereunder, or recovery of
possession of the premises in the hands of an attorney, or files suit upon the
same, the Tenant agrees to pay the Landlord the reasonable attorney fees and
court costs thereby incurred by the Landlord, together with interest at the
legal rate for all unpaid sums from the date of default.

19.  The Landlord shall have the right to transfer and assign, in whole or in
     part, all and every feature of Landlord's right and obligations hereunder
     and in the leased premises, the building and land parcel. Such transfers or
     assignments may be made either to a corporation, trust company, individual
     or group of individuals, and howsoever made, shall in all things be
     respected and recognized by the Tenant, and in the event of any such
     transfer or assignment, whether by absolute conveyance, lease or otherwise,
     the Landlord shall be relieved of any and all obligations, covenants and
     duties provided that:

          a.   The new owner is able to and expressly agrees in writing to
               assume Landlord's obligations under the Lease; and

          b.   The Tenant's funds that the landlord is holding, such as the
               Security Deposit, are given to the new owner.

                             ESTOPPEL CERTIFICATE
                             --------------------

20.  Within ten days after request therefor by Landlord, the Tenant agrees to
deliver in recordable form a certificate to any proposed mortgagee, purchaser or
Landlord, certifying (if such be the case) that this lease is in full force and
effect and that there are no defenses or offsets thereto, or stating those
claimed by Tenant. If Tenant fails to deliver such certificate within such time
from written request, then Tenant appoints Landlord Tenant's attorney-in-fact to
execute same, or Landlord may exercise all remedies applicable to Tenant's
default.

                                    WAIVER
                                    ------

21.  Failure of the Landlord to declare any default immediately upon occurrence
thereof or delay in taking any action in connection therewith shall not waive
such default, but the Landlord shall have the right to declare any such default
at any time and take such action as might be lawful or authorized hereunder,
either in law or in equity.

                           MORTGAGE AND SUBORDINATION

     and substitutions therefor, and to any and all advances made or to be made
     under or upon said mortgages, ground or underlying leases. Tenant agrees,
     to execute any instrument or instruments which the Landlord may deem
     necessary or desirable to effect the subordination of this lease to any or
     all such mortgages, ground or underlying leases. Notwithstanding the
     foregoing, any successor in interest to the Landlord agrees to recognize
     the Tenant's rights under the Lease provided that:

          a.   The Tenant's quiet possession shall not be disturbed if the
               Tenant is not in default under the terms and conditions of this
               Lease; and

          b.   Tenant will attorn and recognize any successor in interest to the
               Landlord for the remaining

       m. Reservation: The submission of this lease for examination does not

          occupant in the building with a greater than proportionate parking
          requirement, they will be expected to pay for off-site parking for the
          additional stalls.
