         By this Lease Landlord leases to Tenant and Tenant leases from
Landlord the Premises in the Building as set forth and described on the
Reference Page. The Reference Page, including all terms defined thereon, is
incorporated as par of this Lease.

1.    USE AND RESTRICTIONS ON USE.

      1.1  The Premises are to be used solely for the purposes stated on the
      Reference Page. Tenant shall not do or permit anything to be done in or
      about the Premises which will in any way obstruct or interfere with the
      rights of other tenants or occupants of the Building or injure, annoy, or
      disturb them or allow the Premises to be used for any improper, immoral,
      unlawful, or objectionable purpose. Tenant shall not do, permit or suffer
      in, on, or about the Premises the sale of any alcoholic liquor without
      the written consent of Landlord first obtained, or the commission of any
      waste. Tenant shall comply with all governmental laws, ordinances and
      regulations applicable to the use of the Premises and its occupancy and
      shall promptly comply with all governmental orders and directions for the
      correction, prevention and abatement of any violations in or upon, or in
      connection with, the Premises, all at Tenant's sole expense. Tenant shall
      not do or permit anything to be done on or about the Premises or bring or
      keep anything into the Premises which will in any way increase the rate
      of, invalidate or prevent the procuring of any insurance protecting
      against loss or damage to the Building or any of its contents by fire or
      other casualty or against liability for damage to property or injury to
      persons in or about the Building or any part thereof. Landlord shall
      maintain the exterior of the Building (but not doorways) in compliance
      with the Americans With Disabilities Act of 1990, as amended.

      1.2  Tenant shall not and shall not direct, suffer or permit any of its
      agents, contractors, employees, licensees or invitees to at any time
      handle, use, manufacture, store or dispose of in or about the Premises or
      the Building any (collectively "Hazardous Materials") flammables,
      explosives, radioactive materials, hazardous wastes or materials, toxic
      wastes or materials, or other similar substances, petroleum products or
      derivatives or any substance subject to regulation by or under any
      federal, state and local laws and ordinances relating to the protection
      of the environment or the keeping, use or disposition of environmentally
      hazardous materials, substances, or wastes, presently in effect or
      hereafter adopted, all amendments to any of them, and all rules and
      regulations issued pursuant to any of such laws or ordinances
      (collectively "Environmental Laws"), nor shall Tenant suffer or permit
      any Hazardous Materials to be used in any manner not fully in compliance
      with all Environmental Laws, in the Premises or the Building and
      appurtenant land or allow the environment to become contaminated with any
      Hazardous Materials. Notwithstanding the foregoing, and subject to
      Landlord's prior consent, Tenant may handle, store, use or dispose of
      products containing small quantities of Hazardous Materials (such as
      aerosol cans containing insecticides, toner for copiers, paints, paint
      remover and the like) to the extent customary and necessary for the use
      of the Premises for general office purposes; provided that Tenant shall
      always handle, store, use, and dispose of any such Hazardous Materials in
      a safe and lawful manner and never allow such Hazardous Materials to
      contaminate the Premises, Building and appurtenant land or the
      environment. Tenant shall protect, defend, indemnify and hold each and
      all of the Landlord Entities (as defined in Article 30) harmless from and
      against any and all loss, claims, liability or costs (including court
      costs and attorney's fees) incurred by reason of any actual or asserted
      failure of Tenant to fully comply with all




   5

      applicable Environmental Laws, or the presence, handling, use or
      disposition in or from the Premises of any Hazardous Materials (even
      though permissible under all applicable Environmental Laws or the
      provisions of this Lease), or by reason of any actual or asserted failure
      of Tenant to keep, observe, or perform any provision of this Section 1.2.

2.  TERM

      2.1  The Term of this Lease shall begin on the date ("Commencement Date")
      which shall be the Scheduled Commencement l;)ate as shown on the
      Reference Page and the date that Landlord shall tender possession of the
      Premises to Tenant. Landlord shall tender possession of the Premises with
      all the work, if any, to be performed by Landlord pursuant to Exhibit B
      to this Lease substantially completed. Tenant shall deliver a punch list
      of items not completed within 30 days after Landlord tenders possession
      of the Premises and Landlord agrees to proceed with due diligence to
      perform its obligations regarding such items. Landlord and Tenant shall
      execute a memorandum setting forth the actual Commencement Date and
      Termination Date.

      2.2  Tenant agrees that in the event of the inability of Landlord to
      deliver possession of the Premises on the Scheduled Commencement Date,
      Landlord shall not be liable for any damage resulting from such
      inability, but Tenant shall not be liable for any rent until the time
      when Landlord can, after notice to Tenant, deliver possession of the
      Premises to Tenant. No such failure to give possession on the Scheduled
      Commencement Date shall affect the other obligations of Tenant under this
      Lease, except that if Landlord is unable to deliver possession of the
      Premises within one hundred twenty (120) days of the Scheduled
      Commencement Date (other than as a result of strikes, shortages of
      materials or similar matters beyond the reasonable control of Landlord
      and Tenant is notified by Landlord in writing as to such delay), Tenant
      shall have the option to terminate ,this Lease unless said delay is as a
      result of: (a) Tenant's failure to agree to plans and specifications; (b)
      Tenant's request for materials, finishes or installations other than
      Landlord's standard except those, if any, that Landlord shall have
      expressly agreed to furnish without extension of time agreed by Landlord;
      (c) Tenant's change in any plans or specifications; or, (d) performance
      or completion by a party employed by Tenant If any delay is the result of
      any of the foregoing, the Commencement Date and the payment of rent under
      this Lease shall be accelerated by the number of days of such delay.

      2.3  In the event Landlord shall permit Tenant to occupy the Premises
      prior to the Commencement Date, such occupancy shall be subject to all the
      provisions of this Lease Said early possession shall not advance the 
      Termination Date.

3. RENT.

      3.1  Tenant agrees to pay to Landlord the Annual Rent in effect from time
      to time by paying the Monthly Installment of Rent then in effect on or
      before the first day of each full calendar month during the Term, except
      that the first month's rent shall be paid upon the execution of this
      Lease. The Monthly Installment of Rent in effect at any time shall be
      one-twelfth of the Annual Rent in effect at such time. Rent for any
      period during the 



   6

      Term which is less than a full month shall be a prorated portion of the
      Monthly Installment of Rent based upon a thirty (30) day month. Said rent
      shall be paid to Landlord, without deduction or offset and without notice
      or demand, at the Landlord's address, as set forth on the Reference Page,
      or to such other person or at such other place as Landlord may from time
      to time designate in writing

      3.2  Tenant recognizes that late payment of any rent or other sum due
      under this Lease will result in | administrative expense to Landlord, the
      extent of which additional expense is extremely difficult and
      economically impractical to ascertain. Tenant therefore agrees that if
      rent or any other sum is not paid three (3) days after it becomes due and
      payable pursuant to this Lease, a late charge shall be imposed in an
      amount equal to the greater of: (a) Fifty Dollars (S50.00), or (b) a sum
      equal to five percent (5%) per month of the unpaid rent or other payment.
      The amount of the late charge to be paid by Tenant shall be reassessed
      and added to Tenant's obligation for each successive monthly period until
      paid. The provisions of this Section 3.2 in no way relieve Tenant of the
      obligation to pay rent or other payments on or before the date on which
      they are due, nor do the terms of this Section 3.2 in any way affect
      Landlord's remedies pursuant to Article 19 in the event said rent or
      other payment is unpaid after date due.

4.  RENT ADJUSTMENTS.

           reasonable life of such improvements in accordance with such
           reasonable life and amortization schedules as shall be determined
           by Landlord in accordance with generally accepted accounting
           principles, with interest on the unamortized amount at one percent
           (1%) in excess of the prime lending rate announced from time to
           time as such by The Northern Trust Company of Chicago, Illinois.

           4.1.2a Notwithstanding the foregoing provisions of this Article to
           the contrary, Landlord agrees that major repairs or replacements to
           the roof of the Building which are capitalized on Landlord's
           financial books and records shall not be included within the
           definition of Direct Costs.

           real or personal, located in the Building and used in connection
           with the operation of the Building and said land. any payments to
           any ground lessor in reimbursement of tax payments made by such
           lessor; and all fees, expenses and costs incurred by Landlord in
           investigating, protesting, contesting or in any way seeking to
           reduce or avoid increase in any assessments, levies or the tax rate

      exceed Direct Expenses paid or incurred in the Base Year (Direct Expenses)
      and/or (ii) Taxes paid or incurred by Landlord in any Lease Year shall
      exceed the amount of such Taxes which became due and payable in the Base
      Year (Taxes), Tenant shall pay as additional for such ear Tenant's 
      Proportionate Share of such excess.

                
      4.3  The annual determination of Direct Expenses shall be made by
      Landlord and, if certified by a nationally recognized firm of public
      accountants selected by Landlord, shall be binding upon Landlord and
      Tenant. Tenant may review the books and records supporting such
      determination in the office of Landlord, or Landlord's agent, during
      normal business hours, upon giving Landlord five (5) days advance written
      notice within sixty (60) days after receipt of such determination, but in
      no event more often than once in any one year
        


           
   8


      period. In the event that during all or any portion of any Lease
      Year, the Building is not fully rented and occupied Landlord may make
      any appropriate adjustment in occupancy-related Direct Expenses for
      such year for the purpose of avoiding distortion of the amount of
      such Direct Expenses to be attributed to Tenant by reason of
      variation in total occupancy of the Building, by employing sound
      accounting and management principles to determine Direct Expenses
      that would have been paid or incurred by Landlord had the Building
      been fully rented and occupied, and the amount so determined shall be
      deemed to have been Direct Expenses for such Lease Year.
     
      4.4  Prior to the actual determination thereof for a Lease Year, Landlord
      may from time to time estimate Tenant's liability for Direct Expenses
      and/or Taxes under Section 4.2, Article 6 and Article 29 for the Lease
      Year or portion thereof. T Landlord will give Tenant written notification
      of the amount of such estimate and Tenant agrees that it will pay, by
      increase of its Monthly Installments of Rent due in such Lease Year,
      additional rent in the amount of such estimate. Any such increased rate of
      Monthly Installments of Rent pursuant to this Section 4.4 shall remain in
      effect until further written notification to Tenant pursuant hereto.
        
      4.5  When the above mentioned actual determination of Tenant's liability
      for Direct Expenses and/or Taxes is made for any Lease Year and when
      Tenant is so notified in writing, then:
        
           4.5.1  If the total additional rent Tenant actually paid pursuant to
                  Section 4.3 on account of Direct Expenses and/or Taxes for the
                  Lease Year is less than Tenant's liability for Direct Expenses
                  and/or Taxes, then Tenant shall pay such deficiency to
                  Landlord as additional rent in one lump sum within thirty (30)
                  days of of Landlord's bill therefor; and
        
           4.5.2  If the total additional rent Tenant actually paid pursuant to
                  Section 4.3 on account of Direct Expenses and/or Taxes for the
                  Lease Year is more than Tenant's liability for Direct Expenses
                  and/or Taxes, then Landlord shall credit the difference
                  against the then next due payments to be made by Tenant under
                  this Article 4. Tenant shall not be entitled to a credit by
                  reason of actual Direct Expenses and/or Taxes in any Lease
                  Year being less than Direct Expenses and/or Taxes in the Base
                  Year (Direct Expenses and/or Taxes).
        
      4.6  If the Commencement Date is other than January 1 or if the
      Termination Date is other than December 31, Tenant's liability for Direct
      Expenses and Taxes for the Lease Year in which said Date occurs shall be
      prorated based upon a three hundred sixty-five (365) day year.
        


5.  SECURlTY DEPOSIT.

Tenant shall deposit the Security Deposit with Landlord upon the execution of
this Lease. Said sum shall be held by Landlord as security for the faithful
performance by Tenant of all the terms,


   9


covenants and conditions of this Lease to be kept and performed by Tenant and
not as an advance rental deposit or as a measure of Landlord's damage in case of
Tenant's default. If Tenant defaults with respect to any provision of this
Lease, Landlord may use any part of the Security Deposit for the payment of any
rent or any other sum in default, or for the payment of any amount which
Landlord may spend or become obligated to spend by reason of Tenant's default,
or to compensate Landlord for any other loss or damage which Landlord may suffer
by reason of Tenant's default. If any portion is so used, Tenant shall within
five (5) days after written demand therefor, deposit with Landlord an amount
sufficient to restore the Security Deposit to its original amount and Tenant's
failure to do so shall be a material breach of this Lease. Except to such
extent, if any, as shall be required by law, Landlord shall not be required to
keep the Security Deposit separate from its general funds, and Tenant shall not
be entitled to interest on such deposit. The Security Deposit or any balance
thereof shall be returned to Tenant at such time after termination of this Lease
when Landlord shall have determined that all of Tenant's obligations under this
Lease have been fulfilled.

6.  ALTERATIONS

      6.1 Except for those, if any, specifically provided for in Exhibit B to
      this Lease, Tenant shall not make or suffer to be made any alterations,
      additions, or improvements, including, but not limited to, the attachment
      of any fixtures or equipment in, on, or to the Premises or any part
      thereof or the making of any such improvements as required by Article 7,
      without the prior written consent of Landlord, which consent shall not be
      unreasonably withheld. When applying for such consent, Tenant shall, if
      requested by Landlord, furnish complete plans and specifications for such
      alterations, additions and improvements.
        
      6.2 In the event Landlord consents to the making of any such alteration,
      addition or improvement by Tenant, the same shall be made using Tenant's
      contractor, subject to approval by Landlord, at Tenant's sole cost and
      expense. If Tenant shall employ any Contractor other than Landlord's
      contractor and such other Contractor or any subcontractor of such other
      Contractor shall employ any non-union labor or supplier, Tenant shall be
      responsible for any and all delays, damages and extra costs suffered by
      Landlord as a result of any dispute with any labor unions concerning the
      wage, hours, terms or conditions of the employment of any such labor. In
      any event Landlord may charge Tenant a reasonable charge to cover its
      overhead as it related to such proposed work.
        
      6.3 All alterations, additions or improvements proposed by Tenant shall be
      constructed in accordance with all governmental laws, ordinances, rules
      and regulations and Tenant shall, prior to construction, provide the
      additional insurance required under Article 11 in such case, and also all
      such assurances to Landlord, including but not limited to, waivers of
      lien, surety company performance bonds and personal guaranties of
      individuals of substance as Landlord shall require to assure payment of
      the costs thereof and to protect Landlord and the Building and appurtenant
      land against any loss from any mechanic's, materialmen's or other liens.
      Tenant shall pay in addition to any sums due to pursuant to Article 4, any
      increase in real estate taxes attributable to any such alteration,
      addition or improvement for so long, during the Term as such increase is
      ascertainable; at Landlord's election said sums shall be paid in the same
      way as sums due under Article 4.

      6.4 All alterations, additions, and improvements in, on, or to the
      Premises made or installed by Tenant, including carpeting, shall be and
      remain the property of Tenant during the Term but, 



   10



      excepting furniture, furnishings, movable partitions of less than full
      height from the floor to ceiling and other trade fixtures shall become a
      part of the realty and belong to Landlord without compensation to Tenant
      upon the expiration or sooner termination of the Term, at which time title
      shall pass to Landlord under this Lease as by a bill of sale, unless
      Landlord elects otherwise. Upon such election by Landlord, Tenant shall
      upon demand by Landlord, at Tenant's sole cost and expense, forthwith and
      with all due diligence remove any such alterations, additions or
      improvements which are designated by Landlord to be removed (other than
      demising walls which Tenant will not be required to move), and Tenant
      shall forthwith and with all due diligence, as its sole cost and expense,
      repair and restore the Premises to their original condition, reasonable
      wear and tear and damage by fire or other casualty expected.

      the structural portions of the roof, walls and foundation of the Building.
      By taking possession of the Premises, Tenant accepts them as being in good
      order, condition and repair and in the condition in which Landlord is
      obligated to deliver them. It is hereby understood and agreed that no
      representations respecting the condition of the Premises or the building
      have been made by landlord to Tenant, except as specifically set forth in
      this Lease. Landlord shall not be liable for any failure to make any
      repairs or to perform any maintenance unless such failure shall persist
      for an unreasonable time after written notice of the need of such repairs
      or maintenance is give to Landlord by Tenant.
        
      7.2 Tenant shall at its own cost and expense keep and maintain all parts
      of the Premises and such portion of the Building and improvements as are
      within the exclusive control of the Tenant in good condition, promptly
      making all necessary repairs and replacements, whether ordinary or
      extraordinary, with materials and workmanship of the same character, kind
      and quality as the original (including, but not limited to, repair and
      replacement of all fixtures installed by Tenant, water heaters serving the
      Premises, windows, glass and plate glass, doors, exterior stairs,
      skylights, and special office entries, interior walls and finish work,
      floors and floor coverings, heating and air conditioning systems serving
      the Premises, electrical systems and fixtures, sprinkler systems, dock
      boards, truck doors, dock bumpers, plumbing work and fixtures, and
      performance of regular removal of trash and debris). Tenant as part of its
      obligations hereunder shall keep the Premises in a clean and sanitary
      condition. Tenant will, as far as possible keep all such parts of the
      Premises from deterioration due to ordinary war and from falling
      temporarily out of repair, and upon termination of this Lease in any way
      Tenant will yield up the Premises to Landlord in good condition and
      repair, loss by fire or other casualty expected (but not excepting any
      damage to glass). Tenant shall, at its own cost and expense, repair any
      damage to the Premises or the Building resulting from and/or caused in
      whole or in part by the negligence or misconduct of Tenant, its agents,
      employees, invitees, or any other persons entering upon the Premises as a
      result of Tenant's business activities or caused by Tenant's default
      hereunder.

      7.3 Except as provided in Article 22, there shall be no abatement of rent
      and no liability of Landlord by reason of any injury to or interference
      with Tenant's business arising from the making of any repairs, alterations
      or improvements in or to any portion of the Building or the




   11


      Premises or to fixtures, appurtenances and equipment in the Building.
      Except to the extent, if any, prohibited by law, Tenant waives the right
      to make repairs at Landlord's expense under any law, statute or ordinance
      now or hereafter in effect.

      7.4 Tenant shall, at its own cost and expense, enter into a regularly
      scheduled preventive maintenance/service contract with a maintenance
      contractor approved by Landlord for servicing all heating and air
      conditioning systems and equipment serving the Premises (and a copy
      thereof shall be furnished to Landlord). The service contract must include
      all services suggested by the equipment manufacturer in the
      operation/maintenance manual and must become effective within thirty (30)
      days of the date Tenant takes possession of the Premises. Landlord may,
      upon notice to Tenant, enter into such a maintenance/ service contract on
      behalf of Tenant or perform the work and in either case, charge Tenant the
      cost thereof along with a reasonable amount for Landlord's overhead.
        
      7.4a Notwithstanding the foregoing provisions of this Article, Tenant may
      use its own qualified resources or purchased maintenance services for the
      heating and air conditioning systems, provided that such resources or
      services are at least equal to those suggested by the equipment
      manufacturers. Finally, Landlord agrees that the heating and air
      conditioning system to be provided pursuant to Article 40 below
      will exclusively service the Premises.

8.  LIENS.

Tenant shall keep the Premises, the Building and appurtenant land and Tenant's
leasehold interest in the Premises free from any liens arising out of any
services, work or materials performed, furnished, or contracted by tenant, or
obligations incurred by Tenant. In the event that Tenant shall not, within
thirty (30) days following the imposition of any such lien, either cause the
same to be released of record or provide T Landlord with insurance against the
same issued by a major title insurance company or such other protection against
the same as Landlord shall accept, Landlord shall have the right to cause the
same to be released by such means as it shall deem proper, including payment of
the claim giving rise to such lien. All such sums paid by Landlord and all
expenses incurred by it in connection therewith shall be considered additional
rent and shall be payable to it by Tenant on demand.

9.  ASSIGNENT AND SUBLETTING.

      9.1 Tenant shall not have the right to assign or pledge this Lease or to
      sublet the whole or any part of the Premises whether voluntarily or by
      operation of law, or permit the use or occupancy of the Premises by anyone
      other than Tenant, and shall not make, suffer or permit such assignment,
      subleasing or occupancy, without the prior written consent of Landlord,
      and said restrictions shall be binding upon any and all assignees of the
      Lease and subtenants of the Premises. In the event Tenant desires to
      sublet, or permit such occupancy of, the Premises, or any portion thereof,
      or assign this Lease, Tenant shall give written notice thereof to Landlord
      at least ninety (90) days but no more than one hundred eighty (180) days
      prior to the proposed commencement date of such subletting or assignment,
      which notice shall set forth the name of the proposed subtenant or
        
        


   12


      assignee, the relevant terms of any sublease or assignment and copies of
      financial reports and other relevant financial reports and other relevant
      financial information of the proposed subtenant or assignee.
        
      9.2 Notwithstanding any assignment or subletting, permitted or otherwise,
      Tenant shall at all times remain directly, primarily and fully responsible
      and liable for the payment of the rent specified in this Lease and for
      compliance with all of its other obligations under the terms, provisions
      and covenants of this Lease. Upon the occurrence of an Event of Default,
      if the Premises or any part of them are then assigned or sublet, Landlord,
      in addition to any other remedies provided in this Lease or provided by
      law, may, at its option, collect directly from such assignee or subtenant
      all rents due and becoming due to Tenant under such assignment or sublease
      and apply such rent against any sums due to Landlord from Tenant under
      this Lease, and no such collection shall be construed to constitute a
      novation or release of Tenant from the further performance of Tenant's
      obligations under this Lease.
        
      9.3 In addition to Landlord's right to approve of any subtenant or 
      assignee, Landlord shall have the option, in its sole discretion, in the
      event of any proposed subletting or assignment, to terminate this Lease,
      or in the case of a proposed subletting of less than the entire Premises,
      to recapture the portion of the Premises to be sublet, as of the date the
      subletting or assignment is to be effective. The option shall be
      exercised, if at all, by Landlord giving Tenant written notice given by
      Landlord to Tenant within sixty (60) days following Landlord's receipt of
      Tenant's written notice as required above. If this Lease shall be
      terminated with respect to the entire Premises pursuant to this Section,
      the Term of this Lease shall end on the date stated in Tenant's notice as
      the effective date of the sublease or assignment as if that date had been
      originally fixed in this lease for the expiration of the Term. If Landlord
      recaptures under this Section only a portion of the Premises, the rent to
      be paid from time to time during the unexpired Term shall abate
      proportionately based on the proportion by which the approximate square
      footage of the remaining portion of the Premises shall be less than that
      of the Premises as of the date immediately prior to such recapture.
        

      9.4 In the event that Tenant sells, sublets, assigns or transfers this
      Lease, Tenant shall pay to Landlord as additional rent an amount equal to
      one hundred percent (100%) of any Increased Rent (as defined below) when
      and as such Increased Rent is received by Tenant. As used in this Section,
      "Increased Rent" shall mean the excess of (i) all rent and other
      consideration which Tenant is entitled to receive by reason of any sale,
      sublease, assignment or other transfer of this Lease, over (ii) the rent
      otherwise payable by Tenant under this Lease at such time. For purposes of
      the foregoing, any consideration received by Tenant in form other than
      cash shall be valued at its fair market value as determined by Landlord in
      good faith.
        

      9.5 Notwithstanding any other provision hereof, Tenant shall have no
      right to make (and Landlord shall have the absolute right to refuse
      consent to) any assignment of this Lease or




   13

      sublease of any portion of the Premises if at the time of either Tenant's
      notice of the proposed assignment or sublease or the proposed commencement
      date thereof, there shall exist any uncured default of Tenant or matter
      which will become a default of Tenant with passage of time unless cured,
      or if the proposed assignee or subleasee is an entity: (a) with which
      Landlord is already in negotiation as evidenced by the issuance of a
      written proposal; (b) is already an occupant of the Building unless
      Landlord is unable to provide the amount of space required by such
      occupant; (c) is a governmental agency; (d) is incompatible with the
      character of occupancy of the Building; or (e) would subject the Premises
      to a use which would: (i) involve increased personnel or wear upon the
      Building; (ii) violate any exclusive right granted to another tenant of
      the Building; (iii) require any addition to or modification of the
      Premises or the Building in order to comply with building code or other
      governmental requirements; or, (iv) involve a violation of Section 1.2.
      Tenant expressly agrees that Landlord shall have the absolute right to
      refuse consent to any such assignment or sublease and that for the
      purposes of any statutory or other requirement of reasonableness on the
      part of Landlord such refusal shall be reasonable.
        
      9.6 Upon any request to assign or sublet, Tenant will pay to Landlord the
      Assignment/Subletting Fee plus, on demand, a sum equal to all of
      Landlord's costs, including attorney's fees, incurred in investigating and
      considering any proposed or purported assignment or pledge of this Lease
      or sublease of any of the Premises (not to exceed $1,000, i.e., in
      addition to the Assignment/Subletting fee) regardless of whether Landlord
      shall consent to, refuse consent, or determine that Landlord's consent is
      not required for, such assignment, pledge or sublease. Any purported sale,
      assignment, mortgage, transfer of this Lease or subletting which does not
      comply with the provisions of this Article 9 shall be void.
        
      9.7 If Tenant is a corporation, partnership or trust, any transfer or
      transfers of or change or changes within any twelve month period in the
      number of the outstanding voting shares of the corporation, the general
      partnership interests in the partnership or the identity of the persons or
      entities controlling the activities of such partnership or trust resulting
      in the persons or entities owning or controlling a majority of such
      shares, partnership interests or activities of such partnership or trust
      at the beginning of such period no longer having such ownership or control
      shall be regarded as equivalent to an assignment of this Lease to the
      persons or entities acquiring such ownership or control and shall be
      subject to all the provisions of this Article 9 to the same extent and for
      all intents and purposes as though such an assignment.

           resulting therefrom, Tenant waiving any right to claim damages for
           such re-entry and expulsion, and without relinquishing Landlord's
           right to rent or any other right given to Landlord under this Lease

           rent, including any amounts treated as additional rent under this
           Lease, for the remainder of the Term plus any other sums provided in
           this Lease to be paid by Tenant for the remainder of the Term.
        
           19.1.4.2 Landlord may, but need not, relet the Premises or any part

           cost thereof, together with Landlord's expenses of reletting,
           including, without limitation, any commission incurred by Landlord.
           If Landlord decides to relet the Premises or a duty to relet is
           imposed upon Landlord by law, Landlord and Tenant agree that
           nevertheless Landlord shall at most be required to use only the same
           efforts Landlord then uses of lease premises in the Building
           generally and that in any case that Landlord shall not be required to
           give any preference or priority to the showing or leasing of the
           Prerniscs over any other space that Landlord may be leasing or have
           available and may place a suitable prospective tenant in any such
           other space regardless of when such other spar; becomes available.
           Landlord shall not be required to observc any instruction given by
           Tenant about any reletting or accept any tenant offered by Tenant
           unless such offered tenant has a credit-worthiness acceptable to
           Landlord and leascs the entire Premises upon terms and conditions
           including a rate of rent (after giving effect to all expenditures by
           Landlord for tenant




   20



           improvements, broker's commissions and other leasing costs) all no
           less favorable to Landlord than as called for in this Lease, nor
           shall Landlord be required to make or permit any assignmcnt or
           sublcase for more than the current term or which Landlord would not
           be required to permit under the provisions of Article 9.

           19.1.4.3 Until such time as Landlord shall elect to terrninate the 
           Lease and shall thercupon be entitled to recover the amounts
           specified in such case in Section 19.13, Tenant shall pay to Landlord
           upon demand the full amount of all rent, including any arnounts
           treated as additional rent under this Lease and other sums reserved
           in this Lcase for the remaining Term, together with the costs of
           repairs, alterations, additions, redecorating and Landlord's expenses
           of reletting and the collection of the rent accruing therefrom
           (including attorney's fees and broker's commissions), as the same
           shall then be due or become due from time to time, less only such
           consideration as Landlord may have received from any reletting of the
           Premises; and Tenant agrees that Landlord may file suits from time to
           time to recover any sums falling due under this Article 19 as they
           become due. Any proceeds of reletting by Landlord in excess of the
           amount then owed by Tenant to Landlord from time to time shall be
           credited against Tenant's future-obligations under this Lcase but
           shall not otherwise be refunded to Tenant or inure to Tenant's
           benefit.
        
      19.2 Landlord may, at Landlord's option, enter into and upon the Premises
      if Landlord determine on its reasonable discretion that Tenant is not
      acting within a commercially reasonable time to maintain, repair or
      replace anything for which Tenant is responsible under this Lease and
      correct the same, without being deemed in any manner guilty of trespass,
      eviction or forcible entry and detainer and without incurring any
      liability for any damage or interruption of Tenant's business resulting
      therefrom. If Tenant shall have vacated the Premises, Landlord may at
      Landlord's option re-enter the Premises a. any time during the last six
      months of the then current Term of this Lease and make any and all such
      changes, alterations, revisions, additions and tenant and other
      improvemcnts in or about the Premises as Landlord shall elect, all without
      any abatement of any of the rent otherwise to be paid by Tenant under this
      Lease.
        
      19.3 If, on account of any breach or default by Tcnant in Tenant's
      obligations under the terms and conditions of this Lease, it shall become
      necessary or appropriate for Landlord to employ or consult with an
      attorney concerning or to enforece or defend any of Landlord's rights or
      remedics arising under this Lcase, Tenant agrees to pay all reasonable
      attorney's fees so incurred. Tenant expressly waives any right to: (a)
      trial by jury; and (b) service of any notice required by any present or

      interest of the Tenant in the Premises shall terminate as of the date of
      such damage as
        


   24



      if such date had been originally fixed in this Lease for the expiration of
      the Term. In the event that neither Landlord nor Tenant exercises its
      option to terminate this Lease, then Landlord shall repair or restore such
      damage, this Lease continuing in full force and effect, and the rent
      hereunder shall be proportionately abated as provided in Section 22.1.
        
      22.3 Landlord shall not be required to repair or replace any damage or
      loss by or from fire or other cause to any panelings, decorations,

      option and as its sole remedy terminate this Lease by delivering written
      notice to Landlord, within fifteen (15) days after the expiration of said
      period of time, whereupon the Lease shall end on the date of such notice
      or such later date fixed in such notice as if the date of such notice was
      the date originally fixed in this Lease for the expiration of the Term;
      provided, however, that if construction is delayel because of changes,
      deletions or additions in construction requested by Tenant, strikes,
      lockouts, casualties, Acts of God, war, material or labor shortages,
      government regulation or control or other causes beyond the reasonable
      control of Landlord, the period for restoration, repair or rebuilding
      shall be extended for the amount of time Landlord is so delayed.
        

      22.5 Notwithstanding anything to the contrary contained in this Article:
      (a) Landlord shall not have any l obligation whatsoever to repair,
      reconstruct, or restore the Premises when the damages resulting from any
      casualty covered by the provisions of this Article 22 occur during the
      last twelve (12) months of the Term or any extension thereof, but if
      Landlord determines not to repair such damages Landlord shall notify
      Tenant within fourty-five (45) days of the damages and if such damages
      shall render any material portion of the Premises untenantable Tenant
      shall have the right to terminate this Lease by notice to Landlord within
      fifteen (15) days after receipt of Landlord's notice effective as of the
      date of the casualty; and (b) in the event the of any indebtedness secured

      of termination to Tenant within fifteen (15) days after such requirernent
      is made by any such holder, whereupon this Lease shall end on the date of
      such damage as if the date of such damage were the date originally fixed
      in this Lease for the expiration of the Term.
        
      22.6 In the event of any damage or destruction to the Building or 
      Premises by any peril covered by the provisions of this Article 22, it

      notice from Landlord to remove forthwith, at its sole cost and expense,

days after such taking, notice terminating this Lease, except that Tenant may
only terminate this Lease by reason of taking or appropriation, if such taking
or appropriation shall be so substantial as to materially interfere with
Tenant's use and occupancy of the Premises. If neither party to this Lcase
