In order to determine the Residual Interest Amount to be paid to Mortgagee at Maturity, Mortgagor shall forward the following documents to Mortgagee, either simultaneously with the sending of the notice of prepayment, and as a condition precedent to such notice being deemed to effective, or ninety (90) days prior to January 1, 1997, if no prepayment has been made, or within thirty (30) days of acceleration of maturity after default or other acceleration: (a) an appraisal of the Premises prepared by an independent M.A.I. appraiser having at least ten (10) years' experience appraising commercial real estate similar to the Premises in the Boston area, which appraisal shall value the Premises as if it were free and clear of all liens and debts but subject to all leases than in effect (the income stream for which will also be considered by the Appraiser in determining the Appraisal value of the Premises); (b) if the Premises are being sold to a third party simultaneously with such payment, the contract of sale, real estate brokerage agreement (if deduction for a brokerage commission is being claimed), and a statement of all closing costs, with supporting data, for which deductions are being claimed; and if the sale is not for a one hundred (100%0 percent interest in the Premises, then the sales price set forth in the contract of sale shall be projected as if one hundred (100%) percent of the Premises were being sold and such projection shall be used for determining the amount due Mortgagee hereunder; additional, the sales price for the purpose of 6 determining the amount due hereunder shall include the amount of all cash payments, deferred payments, debs assumed and the value of all assets, securities, interests, and other consideration received or receivable in connection with such sale; (c) a current rent roll of the Premises, supporting leases, and a certified statement of income and expenses for the twelve (12) month period immediately preceding the date of such notice setting forth all the information necessary to do an appraisal of the Premises; (d) a statement of all other closing costs, with supporting data, for which deductions are being claimed; and (e) a true and correct statement from Mortgagor calculating the Residual Interest Amount. Mortgagor shall promptly furnish Mortgagee with all additional information that Mortgagee may request. If Mortgagee does not agree with any of the conclusions, calculations, computations, valuations or other information supplied by Mortgagor, Mortgagee shall notify Mortgagor in writing and both parties shall in good faith endeavor to resolve such differences. If such disagreement is over the amount of the appraised value of the Premises, Mortgagee shall furnish Mortgagor with an appraisal in conformity to the standards imposed with respect to Mortgagor with an appraisal. If the two appraisals differ by ten (10%) percent or less, the appraised value of the Premises shall be the average valuation of the two appraisals. If the difference is greater than ten (10%) percent, either party shall have the right to require that a third independent M.A.I. appraiser, mutually satisfactory to both Mortgagor and Mortgagee, be selected to appraise the Premises. Such third appraiser shall render his report within thirty (30) days of appointment, which report must not set a valuation lower than the lowest valuation of the appraisals previously submitted nor higher than the highest valuation of the appraisals previously submitted. The valuations set forth in all three appraisals shall be aggregated and the appraised value of the Premises shall be deemed to be the average of all such appraisals. Mortgagor shall pay the cost of all of the appraisals, but it shall have the right to deduct the cost as part of the Approved Closing Costs provided it shall have first secured Mortgagee's written approval of the same (which approval Mortgagee will not unreasonably withhold). If the Mortgagor does not in the time required supply an appraisal from an appraiser meeting the qualifications in item (a) of the immediate preceding paragraph, then Mortgagee may obtain such an appraisal and the mortgagor agrees that any such appraisal obtained by and satisfactory to Mortgagee shall be the appraisal used in determining the amounts due hereunder. If the privilege to 7 prepay is not exercised, the Consolidated Principal Indebtedness together with any fixed interest accrued thereon shall be paid on Maturity and together with the total of (i) Yield Maintenance Amount computed as hereinafter set forth as will cause Mortgagee to have received interest on the Consolidated Principal Indebtedness to Maturity at the Yield Maintenance Rate, PLUS (ii) the Residual Interest Amount, if any, computed as hereinabove set forth. If the Residual Interest Amount has not been determined on the date on which a sale of the Premises or refinancing of the Consolidated Indebtedness is to be consummated, Mortgagor shall nevertheless have the option to close such sale or any refinancing provided (a) it pays the Consolidated Principal Indebtedness, accrued fixed interest, the Yield Maintenance Amount, and all other sums due Mortgagee hereunder other than the Residual Interest Amount; (b) it deposits into an escrow account under an agreement and with an escrow agent satisfactory to Mortgagee such amount that Mortgagee shall designate (which amount shall in no event be less than (i) the amount of any Net Appraisal Value established by an appraiser or (ii) the amount of the sales proceeds received or receivable by Mortgagor in connection with any sale or the amount of the refinancing proceeds in connection with any refinancing, as the case may be; (c) Mortgagee is able to perfect and shall perfect a superior and first lien security interest in such escrow account and funds; and (d) Mortgagee has such assurances that it deems necessary that no party involved in or affiliated with any party involved in any such transaction is insolvent or subject to bankruptcy. Upon the determination of the amount of Residual Interest due Mortgagee, such sum shall be immediately paid to Mortgagee together with the pro-rata share of all interest earned on the funds in the Escrow Account. For reference purposes, this paragraph is called "Post Closing Residual Interest Determination." The Yield Maintenance Amount and the Residual Interest Amount shall be computed by determining the total interest per annum ("Annual Minimum Yield") which would have been earned at the Yield Maintenance Rate or the Residual Interest Amount, as the case may be, for each calendar year, or part of a calendar year ("Yield Year") on the Consolidated Indebtedness or such other portion outstanding from time to time for such Yield Year beginning with the period from January 1, 1991 to December 31, 1991 ("first Yield Year"). There shall be subtracted from the Annual Minimum Yield of the first Yield Year the actual amount of 8 fixed interest paid with respect to the first Yield Year, and the amount by which the Annual Minimum Yield exceeds the actual amounts of fixed interest paid during such period shall be the Yield Maintenance Amount or Residual Interest Amount, as the case may be, as of the last day of the first Yield Year. The Yield Maintenance Amount and the Residual Interest Amount established for the first Yield Year shall be carried forward to the end of the second Yield Year (being the 1992 calendar year). At the end of the second Yield Year there shall be added to the Yield Maintenance Amount and the Residual Interest Amount established at the end of the first Yield Year (a) interest on such Yield Maintenance Amount at the Yield Maintenance Rate and interest on the Residual Interest Amount at the Residual Interest Rate, as applicable, for the period from the end of the first Yield Year to the end of the second Yield Year and (b) the Annual Minimum Yield for the second Yield Year, and from such total there shall be deducted the actual amount of fixed interest paid on the Consolidated Indebtedness outstanding during the second Yield Year and this resulting amount shall become the Yield Maintenance Amount or Residual Interest Amount, as the case may be, to be carried forward to the end of the third Yield Year. In like manner the Yield Maintenance Amount and Residual Interest Amount shall be recomputed from Yield Year to Yield Year to Maturity. Notwithstanding any other provision of this Agreement the Mortgagor may pay any portion of the Yield Maintenance Amount or Residual Interest Amount with accrued interest thereon at the applicable Yield Maintenance Rate or Residual Interest Rate as determined from time to time on any installment payment date upon thirty (30) days' prior written notice to Mortgagee." 3.

Any failure to exercise any option or right hereinabove provided shall not constitute a waiver of the right to exercise the same in the event of any subsequent default. 4.
