         4. TENANT IMPROVEMENTS AND TENANT IMPROVEMENT ALLOWANCE.

                  (a) Tenant shall, at Tenant's sole cost and expense, cause to
         be prepared and submitted to Landlord for Landlord's prior approval,
         plans and specifications (the "Plans"), including, but not limited to,
         all space plans, working drawings, mechanical and engineering drawings,
         disclosing all construction to be performed by Tenant in the Office
         Space (collectively, the "Work"). Landlord's approval of the Plans
         shall not be unreasonably withheld or denied. In the event the Plans
         are disapproved, Tenant shall revise and resubmit the Plans and
         Landlord shall review the same and notify Tenant of its approval or
         disapproval in the same manner as required for the initial submittal.

                  (b) Tenant shall enter into a contract with Executive
         Construction ("Tenant's Contractor") to perform the Work. Prior to
         commencing the Work, Tenant shall submit all written contracts with
         Tenant's Contractor for Landlord's approval. All installations,
         alterations and additions which comprise the Work shall be constructed
         in a good and workmanlike manner and only new and good grades of
         material shall be used. The Work performed by Tenant's Contractor shall
         comply with all applicable insurance requirements, all laws, statutes,
         ordinances and regulations of the Village of Niles, the State of
         Illinois and the United States of America. Tenant shall permit Landlord
         to observe all construction operations within the Office Space
         performed by Tenant's Contractor. No silence or statement by Landlord's
         supervisor shall be deemed or

                                       2
<PAGE>

         construed as an assumption by said supervisor or Landlord of any
         responsibility for or in relation to the construction of the Office
         Space or any guarantee that the Work complies with laws, complies with
         the Plans, or is suitable or acceptable to Tenant for Tenant's intended
         business purposes.

                  (c) Tenant, at its sole cost and expense, shall file all
         necessary plans with the appropriate governmental authorities having
         jurisdiction over the Work. Tenant shall be responsible for obtaining
         all permits, authorizations and approvals necessary to perform and
         complete the Work. Tenant shall not commence the Work until the
         required permits authorizations and approvals for such work are
         obtained and delivered to Landlord.

                  (d) Tenant shall at all times keep the Office Space and the
         balance of the Premises and adjacent areas free from accumulations of
         waste materials or rubbish caused by its suppliers, contractors or
         workmen. Landlord reserves the right to do clean-up at the expense of
         Tenant if Tenant fails to comply with Landlord's reasonable cleanup
         requirements. At the completion of the Work, Tenant's Contractor shall
         forthwith remove all rubbish and all tools, equipment and surplus
         materials from and about the Office Space and Building. Any damage
         caused by Tenant's Contractor to any portion of the Building or to any
         property of Landlord shall be repaired forthwith by Tenant at its
         expense to its condition prior to such damage.

                  (e) Tenant and Tenant's Contractor shall assume responsibility
         for the prevention of accidents and shall take all reasonable safety
         precautions with respect to the Work and shall comply with all
         reasonable safety measures initiated by Landlord and with all
         applicable laws, ordinances, rules, regulations and orders applicable
         to the Work including those of any public authority for the safety of
         persons or property. Tenant shall advise Tenant's Contractor to report
         to Landlord any injury to any of its agents or employees and shall
         furnish Landlord a copy of the accident report filed with its insurance
         carrier within three (3) days of its occurrence.

                  (f) Provided no default exists under this Lease, Landlord
         shall pay, as Landlord's contribution to the costs of construction of
         the Work, a sum equal to THREE HUNDRED NINETY THOUSAND AND NO/100
         ($390,000.00) DOLLARS ("Tenant Improvement Allowance"). Tenant shall
         pay for the entire cost of the Work including, but not limited to, all
         labor, material, permits, architectural and engineering fees, and
         permit fees, in excess of the Tenant Improvement Allowance. The Tenant
         Improvement Allowance shall be paid to Tenant's Contractor in
         installments by the Landlord as the Work progresses within ten (10)
         days of presentation by Tenant and Tenant's Contractor of reasonable
         documentation evidencing (i) the amounts due, in relation to the Work,
         to the Tenant's Contractor and any subcontractors and materialmen,
         including, but not limited to, general contractor's statement and
         partial and final lien waivers, as the case may be, covering all Work
         for which the Tenant's Contractor is requesting payment; (ii) the
         percentage of the Work completed; (iii) a sworn statement from Tenant
         setting forth in detail all contractors and material suppliers with
         whom Tenant has contracted, their addresses, work or materials to be
         furnished, amounts of contracts, amounts paid to date, amounts of
         current payments and balances due; and (iv) a report by the architect
         that prepared the Plans certifying that the Work has been completed and
         materials are in place

                                       3
<PAGE>

         as indicated by the request for payment of Tenant's Contractor. Tenant
         shall be responsible for obtaining and submitting to Landlord all
         documentation reasonably required by the Landlord in relation to draw
         requests. Payments of the Tenant Improvement Allowance shall never
         exceed, in the aggregate, the lesser of (i) the remaining unpaid amount
         of the Tenant Improvement Allowance, or (ii) that amount equal to
         ninety percent (90%) of the cost of all Work completed in accordance
         with the Plans, as evidenced by the documentation furnished with such
         request (including lien waivers). The ten percent (10%) of the cost of
         the Work not disbursed (the "Holdback") shall be disbursed to Tenant's
         Contractor with the final payment for the Work. The disbursement of the
         Tenant Improvement Allowance and any additional funds due from Tenant
         shall be made through a construction escrow ("Construction Escrow")
         established with Chicago Title Insurance Company ("Escrowee"), or such
         other title company selected by Landlord. The parties shall execute a
         standard form of construction escrow agreement utilized by the Escrowee
         with such revisions thereto as may be necessary to conform to the
         provisions hereof. The parties and any contractor employed by Tenant
         and all subcontractors thereof shall furnish to the Escrowee such other
         documents, information and undertakings as may be reasonably requested
         by the Escrowee to enable it to advise Landlord and Tenant, with
         respect to the periodic disbursement made through the construction
         escrow and lien waivers are in proper form for the purpose of releasing
         and waiving any and all rights to file mechanics lien claims against
         the Office Space and the Premises or any portion thereof and that there
         are no liens of public record. Landlord shall fund the Tenant
         Improvement Allowance into the Construction Escrow periodically by the
         transfer of funds upon approval of documents submitted in connection
         with each construction draw and upon the Escrowee's determination, with
         respect to the periodic disbursements made through the construction
         escrow, that it is prepared to advise Landlord that all statements and
         lien waivers are in proper form for the purpose of releasing and
         waiving any and all rights to file mechanics lien claims against the
         Office Space or any portion thereof and that there are no liens of
         public record through the date of disbursement of funds.
         Notwithstanding the foregoing, if at any time during the course of
         performance of the Work the total unpaid cost of completing the Work as
         indicated by any of the sworn statements provided hereunder exceeds the
         balance of the Tenant Improvement Allowance, Landlord need not make
         further disbursements of Tenant Improvement Allowance until Tenant has
         deposited in the Construction Escrow the sum necessary, along with the
         balance of the Tenant Improvement Allowance, to make all available
         funds equal to the unpaid cost of construction or has paid such excess
         costs directly. The final payment for the Work (inclusive of the entire
         Holdback) shall not be made until the architect who prepared the Plans
         shall have certified to Landlord and Tenant that the Work is
         substantially complete in accordance with the Plans, any applicable
         certificate of occupancy or other governmental license or permit has
         been issued, all final waivers of lien have been deposited with the
         Escrowee and the Escrowee is prepared to advise Landlord that there are
         no liens of public record resulting from the Tenant's Work and is
         prepared to issue a date-down endorsement

                                       4
<PAGE>

         to Landlord's then existing Title Insurance Policy issued by Chicago
         Title Insurance Company free of any exceptions relating to Work. The
         payment for expenses incurred in connection with the Construction
         Escrow and issuance of the Title Insurance Policy date-down endorsement
         shall be paid from the Tenant Improvement Allowance as an element of
         the cost of the Work.

         5. BROKERS. Landlord and Tenant hereby represent and warrant to one
another that it has not dealt with any broker, salesperson, finder or other
party who is or might be entitled to a commission, fee or other compensation in
connection with the transaction contemplated by this Amendment except for Grubb
& Ellis and P.M. Realty Group/Ecker (collectively, the "Brokers"). Landlord and
Tenant each hereby agree to indemnify, defend and hold the other harmless from
and against all loss, cost and expense (including, without limitation, attorneys
fees) arising out of the breach by the other party of the foregoing
representation and warranty.

         6. NO OTHER MODIFICATION. The Lease is only modified as set forth
herein and in all other respects remains in full force and effect.

         7. SUCCESSORS AND ASSIGNS. This Amendment shall be binding upon and
shall inure to the benefit of the parties hereto and their respective successors
and assigns.

         8. MODIFICATION. This Amendment may not be modified or amended except
by written agreement executed by the parties hereto.

         9. GOVERNING LAW. The validity, meaning and effect of this Amendment
shall be determined in accordance with the laws of the State of Illinois.

         10. COUNTERPARTS. This Amendment may be executed in two counterparts,
each of which shall be deemed an original, but all of which together shall
constitute one and the same instrument.

         11. SEVERABILITY. Landlord and Tenant intend and believe that each
provision in this Amendment comports with all applicable local, state and
federal laws and judicial decisions. However, if any provision in this Amendment
is found by a court of law to be in violation of any applicable ordinance,
statute, law, administrative or judicial decision, or public policy, and if such
court should declare such provision to be illegal, void or unenforceable as
written, then such provision shall be given force to the fullest possible extent
that the same is legal, valid and enforceable and the remainder of this
Amendment shall be construed as if such provision was not contained therein.
