The adjustments hereunder shall be calculated or paid in an amount based upon a fair and reasonable estimated accounting performed and agreed to by representative of Sellers and Purchaser at the Closing. Subsequent final adjustments and payments shall be made in cash or other immediately available funds as soon as practicable after the Closing Date, and in any event within ninety (90) days after the Closing Date, based upon an agreed accounting performed by representatives of Sellers and Purchaser. In the event the parties have not agreed with respect to the adjustments required to be made pursuant to this Section 8.03 within such ninety-day period, upon application by either party, the Accountant shall determine any such adjustments which have not theretofore been agreed to between Sellers and Purchaser. The charges of the Accountant shall be borne fifty percent (50%) by Sellers and fifty percent (50%) by Purchaser. (d) Sellers and Purchaser agree that the Title Company shall retain from the Sellers' Funds such amounts as may be necessary to discharge any monetary encumbrances (other than Permitted Encumbrances) affecting any Facility. The closing statement agreed to among the Title Company, Sellers and Purchaser shall reflect such use of the Sellers' Funds. (e) Purchaser and Sellers acknowledge that (x) Sellers have applied for and there is pending with respect to the Facility located in Silver Spring, Maryland a Certificate of Need for sixteen (16) skilled nursing beds and (y) the Purchase Price has been determined and agreed upon in recognition of the fact that such Certificate of Need will not be granted prior to the Closing. If, for any reason, such Certificate of Need is irrevocably approved and issued prior to the Closing, the Purchase Price shall be increased by an amount equal to $1,000,000. Furthermore, if such Certificate of Need shall be irrevocably approved and issued on or before the date two (2) years after the Closing Date, Purchaser shall pay to Sellers, within ten (10) days thereafter, $1,000,000 in immediately available federal funds to such account or accounts as Sellers may designate. The provisions of this section shall survive the Closing. (f) Purchaser and Sellers acknowledge that the Purchase Price of $320,000,000 is based in part on the minimum and percentage rentals payable by MSLS as tenant under the Facilities Leases. Under the Facilities Leases, the percentage rents are equal to the product of net receipts over an aggregate sales breakpoint of $71,513,000. If, prior to the Closing Date, the aggregate sales breakpoint is reduced pursuant to lease amendments to the Facilities Leases, in form and substance reasonably acceptable to Purchaser, the Purchase Price shall be increased by an amount equal to nine (9) times the product of (x) the reduction in the aggregate net sales breakpoint and (y) 4.5%; provided, however, in no event shall the Purchase Price increase pursuant to this Section by an amount in excess of Two Million Dollars ($2,000,000). An example of such an adjustment is set forth on Exhibit B. -28-
