WITNESSETH: In consideration of the rents hereinafter reserved and the covenants and agreements herein contained, Lessor does hereby lease unto Lessee, and Lessee does hereby take and lease from the Lessor, that certain parcel of land and improvements thereon known as the Tuxedo Park Executive Conference Center located at Tuxedo Park, New York, (the "Premises" or "Leased Premises"), for use as a corporate conference center. This lease is granted and accepted subject to the covenants, agreements, terms, conditions and restrictions hereinafter set forth. 1. LEASE TERM: The term of this lease shall be 120 months, commencing January 1, 1990 and ending December 31, 1999 (the "Term").

Upon receipt of the foregoing cancellation notice, this lease shall be deemed terminated and of no further force or effect and the parties respectfully discharged of further obligations hereunder, except that Lessor shall reimburse the Lessee the then unamortized balance of the leasehold improvements made by the Lessee. In the event that Lessee is ordered to permanently vacate the Premises by a governmental agency or department with appropriate jurisdiction, the six month written lease cancellation notification period is waived and Lessee shall vacate Premises immediately. In such event, Lessor shall reimburse Lessee for one-half of the then unamortized balance of the leasehold improvement made by the Lessee. 1 2. USE: Said Premises shall be used by the Lessee as an executive conference center, and for no other purpose whatever without the prior written approval of the Lessor. Lessee shall comply with the requirements of all statutes, regulations, ordinances, and orders of any Federal, State, City, County, or any other public authority affecting the use or occupancy of, or activity in, the Leased Premises, or in the Building in which the Leased Premises are located. 3. RENT: Lessee agrees to pay Lessor, in lawful money of the United States of America, as rent for the Leased Premises, without demand or deductions, at Lessor's office at 100 Park Avenue, New York, New York, or at such other place as Lessor may designate in writing to the Lessee, with all rent checks to be made payable to The Tuxedo Park Executive Conference Center Proprietorship or such other person, firm or corporation as the Lessor may designate in writing, the following: The total rent for the term of ten years shall be Seven hundred thirty nine thousand two hundred ($739,200.00) dollars, payable in equal monthly installments of six thousand one hundred sixty ($6,160.00) dollars, in advance, commencing the first month of the term herein, and thereafter on the first day of each and every month during the term thereof. 4. Additional Rent: (a) Lessee shall pay as additional rent a per person per day usage rent of twenty-five dollars. For purposes of illustration, if twenty individuals were to occupy the Premises for five days, the total additional rent for this five day period would be $2,500.00 (20 individuals x 5 days x $25). Lessee shall maintain a written log setting forth the names and dates of arrival and departure of every individual that utilizes the Premises. This log shall be made available for inspection by the Lessor at any time without prior notice to Lessee. This additional rent is due quarterly and shall be paid within forty-five days after the quarter ends. (b) Lessee shall pay as additional rent all operating expenses of the Premises. The term "operating expenses" is defined as including, without limitation, any and all expenses incurred by Lessor in connection with the cleaning, heating, lighting, air conditioning, servicing, operation, maintenance and repair of the building, its physical, electrical, and mechanical systems, and related exterior appurtenances, and ground rent increases, if any, and excluding only: interest and amortization of mortgages, depreciation of the Building, compensation paid to officers or executives of Lessor (other than management fees at going market rates), and income or franchise taxes or other such taxes imposed or measured by the income of the Lessor from the operation of the Building. (c) Lessee agrees to pay as additional rent all water and sewage charges and all real property taxes of every kind, character and description (including special assessments, if any), levied and assessed upon the Building and land, of which the Leased Premises are a part. Copies of bills shall be conclusive evidence of the amounts to be paid by Lessee.

INSURANCE: Lessee shall, at its own cost and expense, maintain with --------- responsible companies approved by Lessor a) comprehensive general liability insurance against all claims, demands or actions for injury to or death of person or damage to property to the limit of not less than $1,000,000.00 per occurrence, which insurance shall name Lessor, its agents, employees, contractors, licensees and invitees as additional insureds; b) fire insurance with extended coverage, vandalism, 3 malicious mischief, and flood endorsements covering the Premises and all fixtures, equipment, furnishings, to the extent of at least one hundred (100%) percent of their replacement value, and in any event in an amount sufficient to prevent Tenant from becoming a co-insurer under provisions of applicable policies.
