("Landlord") dated December 29, 1999 ("Master Lease"), a copy of which is attached hereto as Exhibit A and made a part hereof, wherein Sublessor rented space in the building located at 748 Springdale Drive, Exton, Pennsylvania (the "Building"). The space which is subject to the Master Lease is called the "Premises". B. Sublessor is transferring certain of its insurance business and Sublessee or an affiliate will thereafter be servicing certain of such business. Sublessee desires to sublease from Sublessor the entire Premises, which constitutes one hundred percent (100%) ("Sublessee's Percentage") of the Premises and Sublessor will retain zero percent (0%) ("Sublessor's Percentage") of the Premises. NOW, THEREFORE, in consideration of the mutual promises, covenants and conditions hereinafter set forth, the parties agree as follows: TERMS AND CONDITIONS 1. Premises: Sublessor hereby leases the Premises to Sublessee, and Sublessee hereby leases the Premises from Sublessor for those uses set forth in the Master Lease and for no other purpose. 2. Term: The term of this Sublease shall commence on January 1, 2003 and shall expire December 31, 2004. This Sublease shall automatically expire if the Master Lease expires or is terminated. 3. Rental: Sublessee hereby agrees to pay to Sublessor Sublessee's Percentage of the same rent as computed, required and set forth in the Master Lease, payable in monthly installments due and payable on the date payable under the Master Lease at Sublessor's office at 580 Walnut Street, Cincinnati, Ohio 45202 or at such other place as Sublessor may from time to time designate by written notice to Sublessee. 4. Renewal: Provided the Master Lease will, according to its terms, be in effect for the full renewal term, Sublessee shall have the right to renew this Sublease for one additional term of two years. Sublessee shall exercise its renewal rights by written notice to Sublessor not later than one hundred twenty (120) days prior to the end of the then expiring term. 5. Representations: Sublessor hereby warrants and represents that it is now leasing the Premises pursuant to the terms and provisions set forth in the Master Lease, that a true and complete copy of the Master Lease is attached hereto as Exhibit A, that the Master Lease is in full force and effect, and that Sublessor has a valid leasehold interest in the Premises under the Master Lease; that neither the Master Lease nor any of the obligations, duties, and responsibilities of the Sublessor or of the Landlord under the Master Lease ("Master Landlord") have been amended, modified, or altered in any manner whatsoever; and that there exists no circumstance, condition or act of default which would entitle or permit the Master Landlord to terminate the Master Lease or to abridge any rights of Sublessor as Tenant thereunder. Sublessor covenants that it will not modify or surrender the Master Lease without the prior written consent of Sublessee, and represents that is has full right, power and authority under the Master Lease and otherwise to enter into this Sublease. 6. Master Lease: A. All the obligations contained in the Master Lease conferred and imposed upon Sublessor (as Tenant therein) shall be borne by Sublessor and Sublessee in accordance with the Sublessor's Percentage and the Sublessee's Percentage, respectively, except as modified and amended by this Sublease, and all rights and privileges contained in the Master Lease conferred upon Sublessor (as Tenant therein), are hereby conferred and imposed upon Sublessee, to the extent of Sublessee's Percentage. Sublessor covenants and agrees it will make payment of the rentals reserved under the Master Lease as and when due, will perform Sublessor's insurance obligations under the Master Lease, and will otherwise fully and faithfully perform the terms and conditions of the Master Lease with respect to the Sublessor's Percentage. Sublessee covenants and agrees to otherwise fully and faithfully perform the terms and conditions of the Master Lease and the Sublease on its part to be performed. Neither the Sublessor nor Sublessee shall do or cause to be done any act which would or might cause the Master Lease, or the rights of Sublessor as tenant under the Master Lease to be endangered, cancelled, terminated, forfeited or surrendered, or which would or might cause Sublessor to be in default thereunder or liable for any damage, claim or penalty. Sublessee agrees, as an express inducement for Sublessor executing this Sublease, that if there is any conflict between the provisions of the Master Lease and this Sublease which would permit Sublessee to do or cause to be done any act which is prohibited by the Master Lease then the provisions of the Master Lease shall prevail. B. Sublessee shall pay to Sublessor, within ten (10) days after demand therefor by Sublessor, Sublessee's Percentage of any and all sums (except fixed annual rent payable under the Master Lease) due pursuant to the Master Lease. Sublessor shall not demand such payment prior to the date which is thirty (30) days before the date any such sum shall be due and owing under the Master Lease. C. Notwithstanding anything to the contrary herein contained, Sublessor shall have no duty itself to perform any obligations of the Master Landlord, nor shall such default of the Master Landlord affect this Sublease or waive or defer the performance of any of Sublessee' s obligations hereunder; provided, nevertheless, that in the event of any such default or failure of performance by Master Landlord, Sublessor agrees, upon notice from Sublessee, to make immediate demand upon Master Landlord to perform its obligations under the Master Lease. 2 7. Default: A. If Sublessee defaults in the performance of any of its obligations hereunder, and such default continues for five (5) days after the giving of notice of such default with respect to the failure to pay any monies, or ten (10) days after the giving of notice of default with respect to the failure to perform or comply with any non-monetary obligations of Sublessee hereunder, then Sublessor may cure any such default and add the cost thereof (including reasonable attorneys' fees) to rent or terminate this Sublease upon giving three (3) days notice of termination to Sublessee. Sublessee shall have reasonable additional time beyond ten (10) days to cure a non-monetary default if Sublessee has commenced to cure same within said ten (10) days and thereafter proceeds with due diligence to cure same. B. Notwithstanding anything to the contrary contained herein, Sublessor may terminate this Sublease on three (3) days notice of termination (without having given prior notice of default) if in the reasonable apprehension of Sublessor the act or omission of Sublessee would cause a default under the Master Lease such as would entitle the Master Landlord within said period to terminate the Master Lease. C. In the event of Sublessee's default hereunder Sublessee shall remain liable for all rent and other sums due under the Sublease for the remainder of what would have been the term, for all damages arising out of its default and for all costs incurred in connection with any re-letting of the Premises. Sublessor shall have the right to re-enter and take possession of the Premises in the event of a termination for default. In addition to any and all remedies set forth herein Sublessor shall have all remedies available at law or in equity and any and all remedies shall be cumulative and non-exclusive. Sublessor shall in any event, remain liable for all obligations imposed upon it by the Master Lease. 8.

Any consent by Sublessor and Master Landlord to any act of assignment or subletting shall be held to apply only to the specific transaction thereby authorized. Such consent shall not be construed as waiver of the duty of Sublessee, or the legal representatives or assigns of Sublessee, to obtain from Sublessor or Master Landlord consent to any other or subsequent assignment or subletting, or as modifying or limiting the rights of Sublessor or Master Landlord to assign or sublet without such consent.
