payment of the Remediation Costs.

     3.   Term.  The Escrow Funds shall be held in escrow for a term beginning
          ----

Escrow Funds, as the case may be, in accordance with the terms of this Agreement
(the "Escrow Period").

     4.   Disbursement of Escrow Funds.  The Escrow Agent shall release and
          ----------------------------

conducting any remedial activities incurred by Seller pursuant to the
requirements of Exhibit A attached hereto and made a part hereof ("Remediation
Costs"); and (ii) in accordance with Section 7 hereof.  Remediation Costs shall
include all environmental consulting fees, engineering fees, costs of testing,
sampling and laboratory work, contractor's fees, legal fees, and all other costs
associated with the planning and implementation of work performed pursuant to
Exhibit A.

     5.   Remediation.
          ----------- 
          (a)  From and after the date of the Lease, Seller shall diligently
     pursue to completion the remedial activities identified in Exhibit A (the
     "Remediation") in accordance with all applicable Environmental Laws.  Such
     process shall include, but not necessarily be limited to, the following:

                                       2

 
               (1)  developing a plan or plans of remediation to address the
          Remediation, which plan or plans (individually, a "Remediation Plan"
          and collectively "Remediation Plans") shall be acceptable to Seller
          and Buyer; and

               (2)  implementing each Remediation Plan.

          (b)  A Remediation Plan shall be deemed to have been completed upon
     the first to occur of any of the following events: (i) Buyer approves, in
     writing, the completion of such work; (ii) Seller's environmental
     consultant states in good faith and in exercise of a reasonable degree of
     professional competence that in its professional opinion, the work required
     by the Remediation Plan has been satisfactorily completed and requires no
     further action; or (iii) the expiration or termination of the Lease. ff
     Buyer disagrees with Seller's environmental consultant's opinion concerning
     the completion of the Remediation Plan, then the propriety of the
     consultant's opinion on this issue shall be settled by arbitration in
     accordance with the Commercial Arbitration Rules of the American
     Arbitration Association before a single arbitrator who is a "Certified
     Professional" environmental consultant pursuant to Ohio Revised Code
     Chapter 3746.01(E) and who is appointed in accordance with the Commercial
     Arbitration Rules. The award of the arbitrator shall be limited to (i)
     confirming Seller's environment consultant's opinion, or (ii) requiring
     Seller to conduct further Remediation pursuant to the terms of this
     Agreement, and (a) shall indicate the arbitrator's decision respecting the
     matters in question presented by each party, and (b) shall contain a brief
     statement of the reasons supporting the arbitrator's decision. A judgment
     upon the award rendered by the arbitrator may be entered in any court
     having jurisdiction thereof. Such arbitration 

                                       3

 
     proceeding shall be conducted in Cleveland, Ohio. The pendency of a demand
     for arbitration or any arbitration proceedings hereunder shall not, in and
     of itself, discharge or excuse continuing performance by the parties of
     their obligations and duties under this Agreement or under the Lease. Any
     arbitration arising out of or relating to this Agreement shall include, by
     consolidation, joinder or joint filing, any additional persons or entities
     not parties to this Agreement to the extent reasonably necessary to the
     final resolution of the matter in controversy. Once the Remediation Plan or
     Remediation Plans have been completed or the Lease expires or is
     terminated, the Remediation shall for all purposes of this Agreement be
     deemed completed, the Escrow Agent shall disburse any remaining Escrow
     Funds in accordance with Section 9 and this Agreement shall terminate.

          (c)  As between Seller and Buyer, the work to be performed pursuant to
     this Section 5 shall be supervised and controlled by Seller. Seller shall
     contact, consult and otherwise deal with all governmental authorities in
     connection therewith; provided that Seller shall afford Buyer, and Buyers'
     legal and technical consultants, a reasonable opportunity to review all
     final Remediation Plan(s) and will use its best efforts to cause to be
     considered and incorporated in any proposals or plans any comments or
     suggestions that Buyers' or its consultants may request.

          (d)  In the conduct of the Remediation, Seller agrees to use only URS
     Consultants or another environmental consulting firm that has as a member
     of its firm a "Certified Professional" pursuant to Ohio Revised Code
     Chapter 3746.01(E).

          (e)  The costs of the Remediation to be performed pursuant to this
     Section 5 shall be paid for and discharged first from the Escrow Funds as
     evidence of such costs 

                                       4

 
     is from time to time submitted by Seller to the Escrow Agent for payment.
     Any costs of Remediation in excess of the Escrow Funds shall be paid by
     Seller; provided, however, that Seller shall not be required to expend more
     than $12.0 million for Remediation Costs by the terms of this Agreement.

          (f)  Buyer hereby grants entry and access to the Site to Seller and/or
     Seller's agents, employees, representatives and contractors, as necessary
     to conduct the Remediation pursuant to this Agreement. Buyer shall not
     materially interfere with Seller's conduct of the Remediation and Seller
     shall use reasonable care in its conduct of the Remediation to not
     materially interfere with Buyer's normal business operations at the Site.
     Seller shall have no liability to Buyer for any loss, damage, expense or
     other liability arising as a result of interference with Buyer's normal
     business operations at the Site in the conduct of the Remediation by
     Seller, if Seller has used reasonable best efforts to minimize disturbance
     of Buyer's ability to conduct business at the Site.

     6.   Investment of Funds.  The Escrow Agent shall act as custodian of the

1.   HAZARDOUS WASTE STORAGE SHED./++/
     ----------------------------     

     (A)  Removal of the existing hazardous waste storage shed. The shed is
          assumed to be approximately 10 feet by 10 feet and constructed of
          sheet metal. The shed will be power washed and approximately four
          drums of rinseate will be collected and disposed of as a listed
          hazardous waste. The washed demolition debris will fill approximately
          one roll-off and will be disposed of as a solid waste.

                                                                    $ 10,000

     (B)  Excavation, transportation and disposal as a listed hazardous waste of
          potentially contaminated soil.

                                                                    $ 50,000

     (C)  Sampling of soil at new location for new hazardous waste storage shed
          and construction of new hazardous waste storage shed.
  
                                                                    $ 40,000

2.   EXCAVATION AND DISPOSAL OF SOIL "HOT SPOTS" CONTAMINATED BV VOCS.*
     ------------------------------------------------------------------

                                                                    $809,000

     .    [Subject to final Ohio cleanup standards promulgated under Ohio
          Revised Code Chapter 3746; other remedial methods may be appropriate.]


3.   VOCS IN SHALLOW AQUIFER ON-SITE.
     ------------------------------- 

     Determination of the source and extent of contamination. The source could
     be determined through testing and study of the drains and pipes. The source
     and the extent can be approximated with a soil gas survey under the floor
     slab of the building and east and north of the building. Additional
     monitoring wells would confirm the results of the survey. Determine for
     risk characterization purposes if there are any receptors. Risk assessment
     may be performed based on the results of the characterization activities.
     Some remediation may have to be performed such as source removal and/or
     pump and 

 
     treat. The costs for additional investigation and the installation of a
     pump and treat system and operation for three years are included in the
     cost estimate.

                                                                    $ 250,000


4.   PETROLEUM HYDROCARBONS IN SOIL ON NORTHERN PORTION OF SITE.
     -----------------------------------------------------------

     The source of the contamination is unknown.  Therefore, based on current
     knowledge, it is not possible to determine the party responsible for
     remediating this petroleum contamination. Further investigation will be
     conducted into the source and extent of contamination through a soil gas
     survey and confirmatory sampling.  Sufficient information needs to be
     collected to perform a risk assessment.  Soil excavation or some other type
     of remediation may not be necessary.

     Additional Subsurface Assessment.                              $ 30,000

     Risk Characterization.                                         $ 20,000

5.   VOCS IN DEEP AGUIFER.
     ---------------------

     Low levels of chlorinated VOCs are present in the deep aquifer on the
     southern portion of the site.  However, there is not sufficient information
     to conclude that these contaminants are from upgradient off-site sources.
     The certified professional will gather additional information regarding the
     aquifer flow direction and use from well logs of other wells in the
     vicinity.  In the meantime, it may be prudent not to use the well for any
     purposes until the aquifer system is better understood.

                                                                    $ 10,000

    REGULATORY COMPLIANCE./++/
    ---------------------     

    (A)   Establish an appropriate, monthly hazardous waste tracking system
          including facility-wide labeling at satellite and permanent storage
          areas that meet letter size requirements and contain all necessary
          information. Instruction and training on proper drum labeling
          involving two or three individuals at the facility. Establish a
          hazardous waste management plan, including "Emergency Preparedness and
          Prevention."
                                                                    $109,000

    (B)   Complete air emissions evaluation.  If necessary, prepare permit for
          and/or register all air emissions.

                                                                    $  5,000

                                       2

 
     (C)  Conduct asbestos survey and, if necessary, implement appropriate
          training and compliance plan.

                                                                    $  7,500

     (D)  Install oil/water separators or other devices, as appropriate, on
          sumps and drains.

                                                                    $  3,000

     (E)  Withdraw General Permit for Stormwater from Ohio EPA.

                                                                          $0
