If, after making such adjustments, the actual Operating Profits of the Partnership are less than the estimated Operating Profits utilized to determine the Fair Market Value of the PIC Interest on the Redemption Date, or the actual Operating Losses are greater than the estimated Operating Losses, as the case may be, then PIC shall promptly make a cash payment to the Partnership equal to the difference. In addition to the foregoing, if the Adjusted NEV of the Property has not been determined pursuant to Exhibit V of the Master Transaction Agreement 7 as of the Redemption Date, then promptly following such determination of Adjusted NEV of the Property, if any, pursuant to said Exhibit V, if the Revised NEV of the Property exceeds the NEV of the Property, the Partnership shall pay to PIC, in cash, a sum equal to such difference, and if the NEV of the Property exceeds the Revised NEV of the Property, then PIC shall pay to the Partnership, in cash, a sum equal to such difference. 3.

(B) In addition to, and not in limitation of, any other rights and remedies available to the parties hereto under this Agreement or at law or in equity, each party hereto (on behalf of itself) agrees that, in the event of a breach by any party or its Affiliate (such party, the "breaching party") of any of the covenants set forth in subsection (a) above, such breaching party shall -------------- indemnify, protect, defend and hold harmless the other party(ies) from and against any and all claims, causes of action, losses, liabilities, damages, costs and expenses of whatsoever kind or nature (including, without limitation, reasonable attorneys' fees and expenses and any adverse income tax consequences, including, but not limited to, any interest and penalties) arising out of or in any way resulting from or directly relating to such breach. 4. TAX MATTERS. ----------- (A) If the PIC Interest is redeemed as contemplated by this Agreement and the Internal Revenue Service ("IRS") subsequently questions, or determines that it will examine, investigate or audit any federal income tax returns filed by the Partnership in respect of any taxable year of the Partnership ending in the calendar year in which the Redemption Distribution occurred (the "SUBJECT RETURNS"), then (i) the then Partners of the Partnership shall cause the Partnership to promptly furnish PIC with copies of all written notices received from the IRS, and (ii) PIC shall have the right, at its expense, to represent the Partnership (with professionals of its choice) in dealing with the IRS in connection with any such questions, examination, investigation 8 or audit and in connection with any judicial or administrative proceedings related thereto, in each case only to the extent that they involve any items ("PIC ITEMS") which could have a material impact on PIC, and to make decisions regarding or relating to all PIC Items, except that PIC shall not make any decisions which could materially adversely impact BPLLC and/or Holdings LLC without the prior written consent of BPLLC and Holdings LLC.

(B) BPLLC and Holdings LLC shall cause the Partnership to, and the Partnership shall, report the redemption of the PIC Interest pursuant to this Agreement in a manner consistent with the characterization of such transaction herein, that is, as a withdrawal of PIC from the Partnership and the redemption by the Partnership of the PIC Interest in exchange for the distribution of Partnership property in liquidation of the PIC Interest. BPLLC and Holdings LLC shall submit all Subject Returns to PIC for review and approval no later than thirty (30) days prior to the filing thereof, whether or not PIC is still then a Partner. BPLLC and Holdings LLC agree to modify the reporting of the redemption by the Partnership of the PIC Interest to the satisfaction of PIC to the extent reasonably requested by PIC in writing within thirty (30) days of the receipt of any such returns; provided that, such modification does not materially adversely -------- ---- impact BPLLC and/or Holdings LLC or their Affiliates. Notwithstanding the redemption of the PIC Interest prior to the end of any particular calendar year, BPLLC and Holdings LLC shall each report their participation in the Partnership with respect to any years ending in the calendar year in which the Redemption Distribution occurs consistent with the tax returns approved pursuant hereto and consistent with this Agreement. (C) In accordance with Treasury Regulation Section 1.706-1(c)(ii), for the taxable year of the Partnership in which the Redemption Distribution occurs, PIC's distributive share of the items described in Section 702(a) of the Internal Revenue Code of 1986, as amended, will be determined by reference to an interim closing of the books. In accordance with Treasury Regulation Section 1.751-1(c)(4)(iii), the Partnership, BPLLC, Holdings LLC, and PIC agree that, on the Redemption Date, the fair market value of the Partnership's Section 1245 property (as defined in Section 1245(a)(3) of the Internal Revenue Code of 1986, as amended) is equal to the adjusted tax basis of such property. 5. APPOINTMENT OF SUB-MANAGING PARTNER. Notwithstanding anything to ----------------------------------- the contrary stated in the Partnership Agreement, in the event that the Partnership fails to make the Redemption Distribution to PIC as required by Sections 1 and 2 above on the Redemption Date, then PIC shall have the right, - ---------- - exercisable by written notice to the other Partners of the Partnership, to appoint itself as the sub-managing partner solely for the purpose of making the Redemption Distribution. In such event, PIC shall be solely authorized and empowered, and its sole responsibility shall be, to make the Redemption Distribution on, or as soon as practicable after, the Redemption Date. The Managing Partner shall continue to act as the managing partner under the Partnership Agreement during such time and shall fully and faithfully discharge all obligations 9 and duties of the managing partner under the Partnership Agreement other than those pertaining to the Redemption Distribution (which will be performed and discharged by PIC on behalf of the Partnership). Immediately after the Redemption Distribution shall have been accomplished, PIC shall resign as sub managing partner of the Partnership. Each party hereto further appoints PIC as the attorney-in-fact of the Partnership to prepare, sign, file and record any instruments, agreements or other documents, and to take any other action deemed necessary, useful or desirable by PIC in order to make the Redemption Distribution pursuant to this Agreement in the event that the Managing Partner of the Partnership or the Partnership fails to timely discharge its obligations hereunder within the time periods set forth herein. 6.

Any party hereto shall have the right to initiate an -------- action for specific performance with respect to any breach or default of this Agreement by, or to enforce any obligation under this Agreement of, any other party hereto (including, without limitation, the obligation of the Partnership and the Managing Partner to make the Redemption Distribution pursuant hereto), it being acknowledged and agreed by the parties hereto that monetary damages would be an inadequate remedy and would not adequately compensate any non- defaulting party. In addition to the remedy of specific performance, any non- breaching party may initiate an action seeking actual damages (including, without limitation, increased income tax liability which may result from such breach). Notwithstanding anything to the contrary stated herein, in the Master Transaction Agreement or in the "Transaction Documents" described in such Master Transaction Agreement, the limitations of liability set forth in Article 12 of the Master Transaction Agreement and/or in any other Transaction Document shall not apply to this Agreement, nor shall such limitations limit or restrict any right or remedy available to any party hereunder as a result of the breach or default of any other party under this Agreement. 7.
