                  A. Landlord is granting to Tenant a lease of the real property

Management Co., a corporation organized under the laws of the State of Delaware
("Manager") pursuant to a Management Agreement between Tenant and Manager dated
October ____, 2000, as amended from time to time ("Management Agreement"), a
copy of which is attached hereto as Exhibit A.

                  C. Landlord has required as a condition of its granting the
Lease to Tenant that Tenant assign to Landlord all of Tenant's right, title, and
interest in and to the Management Agreement and that Manager consent to this
Assignment.

                  D. As used herein, "Lease Documents" means the Lease, and all
other documents and agreements executed in connection with the Lease, as
amended, modified, renewed or extended from time to time.

                  NOW, THEREFORE, as an inducement to Landlord to enter into the
Lease Documents and in consideration thereof, and for good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Tenant hereby transfers, assigns, and sets over unto Landlord, its successors

the terms and conditions of this Assignment.

                  1. Representations and Warranties. Tenant represents and
warrants that [i] the copy of the Management Agreement attached hereto as
Exhibit A is a true and correct copy of the Management Agreement; [ii] Tenant's
interest in the Management Agreement is not subject to any claim, set-off, lien
or encumbrance of any kind or nature; [iii] the Management Agreement is in full
force and effect, there have been no modifications, supplements, amendments, or
addenda thereto, and it constitutes the entire agreement between Tenant and
Manager as to the Facility; and [iv] neither Tenant nor Manager, to Tenant's
knowledge, is in default under the Management Agreement.

                  2. Lease Obligations. The parties hereto acknowledge that
this Assignment is made as security for the obligations of Tenant under the
Lease Documents ("Lease Obligations") and that unless and until an Event of
Default (as defined in the Lease) occurs and remains uncured beyond any
applicable grace period, Tenant shall be entitled to the rights, benefits and
privileges of, and to act under, the Management Agreement. Tenant has executed,
or will execute, UCC-1 financing statements covering the rights secured hereby,
and agrees to execute such further instruments as Landlord may reasonably
request to perfect, continue or otherwise further secure the rights granted
herein.

                  3. Default. Upon the occurrence and during the continuance
of any Event of Default under the Lease Documents (which shall constitute a
default under this Assignment) that remains uncured beyond any applicable grace
period, Landlord may elect, at its option at any time, to exercise Tenant's
rights under the Management Agreement or to terminate the Management Agreement.
Landlord shall give written notice of such election to Tenant and Manager and
such election shall become effective on the date specified by Landlord in its
notice (which date shall not be earlier than the date of the notice). Any such
election shall be binding upon Tenant and Manager notwithstanding any provisions
in the Management Agreement to the contrary. Landlord shall not be obligated to
elect either option at any time.

                  4. Amendment; Termination. Tenant shall not amend, modify or
terminate the Management Agreement without the prior written consent of Landlord
(which consent shall not be unreasonably withheld).

                  5. Landlord's Liability. Unless and until Landlord has assumed
in writing Tenant's obligations under the Management Agreement, Landlord shall
have no liability under the Management Agreement. Neither this Assignment nor
any other action on the part of Landlord, except the aforesaid assumption in
writing, shall constitute an assumption by Landlord of any of the obligations of
Tenant under the Management Agreement.

                  6. Enforcement. This Assignment is without prejudice to the
right of Landlord to enforce performance of the Lease Obligations when due, by
suit or in any lawful manner, or to resort to any other security for the
performance of the Lease Obligations, this Assignment being additional,
accumulative and concurrent security for the performance of the Lease
Obligations. The enumeration of certain rights, privileges and options in this
Assignment as vested in Landlord, or its successors and assigns, is not and
shall not be construed as a waiver of, nor to impair in any way, other rights of
Landlord or its successors or assigns, either at law or in equity, independent
of this Assignment, concerning this or any of the liabilities, obligations,
indebtedness, or collateral security securing the Lease Obligations. Landlord,
its successors and assigns, shall have the right to proceed against the security
granted hereunder or any other security granted for the performance of the Lease
Obligations and to proceed against all security at the same time or against
individually pledged or liened assets from time to time at the sole election of
Landlord. No action against any specific security granted for the Lease
Obligations shall be a bar to any subsequent action or actions against all or
any other security granted for the Lease Obligations.

                  7. Cure. Tenant agrees that Landlord shall have the right at
any time (but shall have no obligation) to take in its or in the name of Tenant
or otherwise, such actions as Landlord may at any time or from time to time
reasonably determine to be necessary to cure any default of Tenant under the
Management Agreement. Landlord shall incur no liability on account of any lawful
action taken by it or in its behalf in good faith pursuant to the foregoing
sentence or otherwise hereunder, whether or not the same shall prove to be
improper, inadequate or invalid in whole or in part and, Tenant agrees to
indemnify and hold Landlord harmless from and against any and all loss, cost,
liability or expense (including, but not limited to, reasonable attorneys' fees
and expenses) in connection with any such action or actions.

                  8. Power of Attorney. Effective upon the occurrence and during
the continuance of an Event of Default, Tenant hereby


                                      -3-
<PAGE>   4

irrevocably constitutes and appoints Landlord its true and lawful
attorney-in-fact to act in Tenant's name or in Landlord's name or otherwise, to
enforce all rights of Tenant under the Management Agreement, and such power of
attorney, being coupled with an interest, is irrevocable until the Lease
Obligations are paid in full.

                  9. Notices. All notices hereunder shall be in writing, and
delivered personally, or by nationally recognized overnight courier service, or
by United States mail, postage prepaid, to the address set forth herein or to
such other address as may hereafter be provided in writing to the other party.
All notices shall be deemed to be given upon the earlier of actual receipt or
three days after deposit in the United States mail or one day after deposit with

                  10. Binding Effect and Assignment. This Assignment and any
actions taken by Landlord pursuant to and in accordance with this Assignment
shall be binding upon Tenant, Manager and their respective successors and
assigns, and shall inure to the benefit of Landlord and its successors and
assigns. Landlord may assign its rights hereunder, but Tenant may not assign its
rights or obligations under this Assignment without the prior written consent of
Landlord.

                  11. Governing Law. This Assignment shall be governed by and
construed in accordance with the internal laws of the State of Ohio, without
giving effect to the conflict of laws rules thereof.

                  12. Manager's Consent. Tenant hereby consents to the terms
and conditions of the Consent of Manager to Collateral Assignment of Management
Agreement attached hereto.
