Each Interest Period specified in a Notice of Interest Rate Election shall comply with the provisions of the definition of Interest Period. Upon receipt of a Notice of Interest Rate Election from the Borrower pursuant to subsection (a) above, the Administrative Agent shall notify each Bank the same day as it receives such Notice of Interest Rate Election of the contents thereof, the interest rates determined pursuant thereto and the Interest Periods (if different from those requested by the Borrower) and such notice shall not thereafter be revocable by the Borrower.

Whenever any payment of principal of, or interest on, the Eurodollar Loans shall be due on a day which is not a Business Day, the date for payment thereof shall be extended to the next succeeding Business Day unless such Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. 31 Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent that the Borrower shall not have so made such payment, each Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Administrative Agent, at the Federal Funds Rate. FUNDING LOSSES. If the Borrower makes any payment of principal with respect to any Eurodollar Loan (pursuant to Article II, VIII or X or otherwise) on any day other than the last day of the Interest Period applicable thereto or if Borrower shall deliver a Notice of Interest Rate Election specifying that a Eurodollar Loan shall be converted on a date other than the last day of the then current Interest Period applicable thereto, the Borrower shall reimburse each Bank within 15 days after certification of such Bank of such loss or expense (which shall be delivered by each such Bank to Administrative Agent for delivery to Borrower) for any resulting actual loss or expense incurred by it (or by an existing Participant in the related Loan), including, without limitation, any actual loss incurred in obtaining, liquidating or employing deposits from third parties related to such Eurodollar Loan, but excluding loss of margin for the period after any such payment, provided that such Bank shall have delivered to Administrative Agent and Administrative Agent shall have delivered to the Borrower a certification as to the amount of such actual loss or expense, which certification shall set forth in reasonable detail the basis for and calculation of such actual loss or expense and shall be conclusive in the absence of demonstrable error. COMPUTATION OF INTEREST AND FEES. All interest and fees hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Adjusted Base Rate at times when the Adjusted Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable interest and fees shall be determined by the Administrative Agent in accordance with the terms of this Agreement, and such determination shall be conclusive absent manifest error. PRO RATA TREATMENT. 1. Subject to Section 8.4, if at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties. If any Bank shall obtain payment in respect of any principal of or interest on any of its Loans resulting in such Bank receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Bank, 32 then the Bank receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Banks to the extent necessary so that the benefit of all such payments shall be shared by the Banks ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; PROVIDED that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Bank as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). If any Bank shall fail to make any payment required to be made by it pursuant to Section 2.9(b), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Bank to satisfy such Bank's obligations under Section 2.9(b) until all such unsatisfied obligations are fully paid.

any of the Borrower, BPI or any of their respective Consolidated Subsidiaries shall make an assignment for the benefit of creditors, or admit in writing its inability to pay or generally fail to pay its debts as they mature or become due, or shall petition or apply for the appointment of a trustee or other custodian, liquidator or receiver of any of the Borrower, BPI or any of their respective Consolidated Subsidiaries or of any substantial part of the properties or assets of any of such parties or shall commence any case or other proceeding relating to any of the Borrower, BPI or any of their respective Consolidated Subsidiaries under any bankruptcy, reorganization, arrangement, insolvency, readjustment of debt, dissolution or liquidation or similar law of any jurisdiction, now or hereafter in effect, or shall take any action to authorize or in furtherance of any of the foregoing, or if any such petition or application shall be filed or any such case or other proceeding shall be commenced against any of the Borrower, BPI or any of their respective Consolidated Subsidiaries and (i) any of the Borrower, BPI or any of their respective Consolidated Subsidiaries shall indicate its approval thereof, consent thereto or acquiescence therein or (ii) any such petition, application, case or other proceeding shall continue undismissed, or unstayed and in effect, for a period of ninety (90) days, except, with respect solely to such parties other than the Borrower and BPI, any of the foregoing constitutes a Non-Material Breach; a decree or order is entered appointing any trustee, custodian, liquidator or receiver or adjudicating any of the Borrower, BPI or any of their respective Consolidated Subsidiaries bankrupt or insolvent, or approving a petition in any such case or other proceeding, or a decree or order for relief is entered in respect of any of the Borrower, BPI or any of their respective Consolidated Subsidiaries in an involuntary case under federal bankruptcy laws as now or hereafter constituted, except, with respect solely to such parties other than the Borrower and BPI, any of the foregoing constitutes a Non-Material Breach; there shall remain in force, undischarged, unsatisfied and unstayed, for more than thirty (30) days, whether or not consecutive, any uninsured final judgment against any of the Borrower, BPI or any of their respective Consolidated Subsidiaries that, with other outstanding uninsured final judgments, undischarged, unsatisfied and unstayed, against any of such parties exceeds in the aggregate $10,000,000, except, with respect solely to such parties other than the Borrower and BPI, any of the foregoing constitutes a Non-Material Breach; any of the Loan Documents or any material provision of any Loan Document shall be canceled, terminated, revoked or rescinded otherwise than in accordance with the terms thereof or with the express prior written agreement, consent or approval of the Administrative Agent or Required Lenders, as the case may be, or any action at law, suit or in equity or other legal 65 proceeding to make unenforceable, cancel, revoke or rescind any of the Loan Documents shall be commenced by or on behalf of the Borrower or any of the Consolidated Subsidiaries or BPI or any of the Consolidated Subsidiaries, or any court or any other governmental or regulatory authority or agency of competent jurisdiction shall make a determination that, or issue a judgment, order, decree or ruling to the effect that, any one or more of the Loan Documents is illegal, invalid or unenforceable as to any material terms thereof; any "Event of Default" or default (after notice and expiration of any period of grace, to the extent provided), as defined or provided in any of the other Loan Documents, shall occur and be continuing; with respect to any Guaranteed Pension Plan, an ERISA Reportable Event shall have occurred and the Required Banks shall have determined in their reasonable discretion that such event reasonably could be expected to result in liability of the Borrower or any of the Consolidated Subsidiaries or BPI or any of the Consolidated Subsidiaries to the PBGC or such Guaranteed Pension Plan in an aggregate amount exceeding $10,000,000 and such event in the circumstances occurring reasonably could constitute grounds for the termination of such Guaranteed Pension Plan by the PBGC or for the appointment by the appropriate United States District Court of a trustee to administer such Guaranteed Pension Plan; or a trustee shall have been appointed by the United States District Court to administer such Plan; or the PBGC shall have instituted proceedings to terminate such Guaranteed Pension Plan; subject to the Borrower's right to remove Real Estate Assets from the Borrowing Base in accordance with the provisions set forth below in this Article VIII, the failure of any of the Real Estate Assets being included from time to time as Borrowing Base Properties to comply with any of the conditions set forth in the definition of Borrowing Base Properties; without limitation of the other provisions of this Section 8.1, BPI shall at any time fail to be the sole general partner of the Borrower or shall at any time be in contravention of any of the requirements contained in Section 6.1(e) hereof, the last paragraph of Section 6.2, or Section 6.3 (including, without limitation, the last paragraph of Section 6.3); the Note, the Loan, the Obligations or any of the Loan Documents or the exercise of any of the Administrative Agent's or any of the Bank's rights in connection therewith shall constitute a prohibited transaction under ERISA and/or the Code; and immediately upon an event of default under and as specifically defined in the Existing Revolving Credit Agreement once the holders of the indebtedness evidenced by such Existing Revolving Credit Agreement are entitled to accelerate such indebtedness as a result of such event of default. then, and in any such event, so long as the same may be continuing, the Administrative Agent may, and upon the request of the Required Banks shall, by notice in writing to the Borrower, declare all amounts owing with respect to this Agreement, the Notes and the other Loan Documents to be, and they shall thereupon forthwith become, immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived by the Borrower, BPI and each of their respective Consolidated 66 Subsidiaries; PROVIDED that in the event of any Event of Default specified in Section 8.1(g) or 8.1(h), all such amounts shall become immediately due and payable automatically and without any requirement of notice from any of the Banks or the Administrative Agent or action by the Banks or the Administrative Agent. The term "Non-Material Breach" shall refer to a breach of any representation, warranty or covenant contained in this Agreement to which the term "Non-Material Breach" is expressly applied herein, but only to the extent such breach does not (A) materially adversely affect the business, properties or financial condition of the Borrower, BPI or, taken as a whole, the BP Group or (B) adversely affect the ability of the Borrower, BPI or, taken as a whole, the BP Group, to fulfill the Obligations to the Banks and the Administrative Agent (including, without limitation, to repay all amounts outstanding on the Loans, together with interest and charges thereon when due). Notwithstanding the foregoing provisions of this Section 8.1 and in addition to the provisions set forth in the immediately preceding paragraph, in the event of a Default, Event of Default or Non-Material Breach arising as a result of the inclusion of any Real Estate Asset in the Borrowing Base at any particular time of reference, if such Default, Event of Default or Non-Material Breach is capable of being cured by the exclusion of such Real Estate Asset from the Borrowing Base and from all other covenant calculations under Sections 7.1 through 7.7 or otherwise, the Borrower shall be permitted a period not to exceed ten (10) days to submit to the Administrative Agent (with copies to the Administrative Agent for each Bank) a compliance certificate in the form of EXHIBIT D-3 hereto evidencing compliance with all of the covenants set forth in Sections 7.1 through 7.7 (with calculations evidencing such compliance after excluding from Borrowing Base Net Operating Income all of the Net Operating Income generated by the Real Estate Asset to be excluded from the Borrowing Base) and with the Borrowing Base Conditions, and otherwise certifying that, after giving effect to the exclusion of such Real Estate Asset from the Borrowing Base, no Default, Event of Default or Non-Material Breach will be continuing. RIGHTS AND REMEDIES. Upon the occurrence of any Event of Default described in Sections 8.1(g), (h), (l) or (o), the Commitments shall immediately terminate and the unpaid principal amount of, and any and all accrued interest on, the Loans and any and all accrued fees and other Obligations hereunder shall automatically become immediately due and payable, with all additional interest from time to time accrued thereon and without presentation, demand, or protest or other requirements of any kind (including, without limitation, valuation and appraisement, diligence, presentment, notice of intent to demand or accelerate and notice of acceleration), all of which are hereby expressly waived by the Borrower; and upon the occurrence and during the continuance of any other Event of Default, the Administrative Agent may (and upon the demand of the Required Banks shall), by written notice to the Borrower, in addition to the exercise of all of the rights and remedies permitted the Administrative Agent and the Banks at law or equity or under any of the other Loan Documents, declare that the Commitments are terminated and declare the unpaid principal amount of and any and all accrued and unpaid interest on the Loans and any and all accrued fees and other Obligations hereunder to be, and the same shall thereupon be, immediately due and payable with all 67 additional interest from time to time accrued thereon and (except as otherwise provided in the Loan Documents) without presentation, demand, or protest or other requirements of any kind (including, without limitation, valuation and appraisement, diligence, presentment, notice of intent to demand or accelerate and notice of acceleration), all of which are hereby expressly waived by the Borrower. Notwithstanding anything to the contrary contained in this Agreement or in any other Loan Document, the Banks each agree that any exercise or enforcement of the rights and remedies granted to the Administrative Agent or the Banks under this Agreement or at law or in equity with respect to this Agreement or any other Loan Documents shall be commenced and maintained on behalf of the Banks by the Administrative Agent and/or the Banks. The Administrative Agent shall act at the direction of the Required Banks in connection with the exercise of any and all remedies at law, in equity or under any of the Loan Documents or, if the Required Banks are unable to reach agreement, then, from and after an Event of Default, the Administrative Agent may pursue such rights and remedies as it may determine. NOTICE OF DEFAULT. The Administrative Agent shall give notice to the Borrower under Section 8.1(c) and 8.1(d) promptly upon being requested to do so by the Required Banks and shall thereupon notify all the Banks thereof. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default (other than nonpayment of principal of or interest on the Loans) unless the Administrative Agent has received notice in writing from a Bank or Borrower referring to this Agreement or the other Loan Documents, describing such event or condition. Should the Administrative Agent receive notice of the occurrence of an Default or Event of Default expressly stating that such notice is a notice of an Default or Event of Default, or should the Administrative Agent send Borrower a notice of Default or Event of Default, the Administrative Agent shall promptly give notice thereof to each Bank. DISTRIBUTION OF PROCEEDS AFTER DEFAULT. Notwithstanding anything contained herein to the contrary but subject to the provisions of Section 2.12, from and after an Event of Default, to the extent proceeds are received by Administrative Agent, such proceeds will be distributed to the Banks pro rata in accordance with the unpaid principal amount of the Loans (giving effect to any participations granted therein pursuant to Section 11.4(c)). THE ADMINISTRATIVE AGENT APPOINTMENT AND AUTHORIZATION. Each Bank irrevocably appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Administrative Agent by the terms hereof or thereof, together with all such powers as are reasonably incidental thereto. Except as set forth in Sections 9.8 and 9.9, the provisions of this Article IX are solely for the benefit of Administrative Agent and the Banks, and Borrower shall not have any rights to rely on or enforce any of the provisions hereof. In performing its functions and duties under this Agreement, Administrative Agent shall act solely as an agent of the Banks and do not assume 68 and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for the Borrower. AGENCY AND AFFILIATES. The Administrative Agent shall have the same rights and powers under this Agreement as any Bank and may exercise or refrain from exercising the same as though it were not an Administrative Agent, and the Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower, BPI or any Subsidiary or affiliate of the Borrower as if they were not the Administrative Agent hereunder, and the term "Bank" and "Banks" shall include JPMorgan Chase Bank, Citicorp North America, Inc. and Bank of America, N.A., in their individual capacities, and any other Banks that may become party hereto. ACTION BY ADMINISTRATIVE AGENT. The obligations of the Administrative Agent hereunder are only those expressly set forth herein. Without limiting the generality of the foregoing, the Administrative Agent shall not be required to take any action with respect to any Default or Event of Default, except as expressly provided in Article VIII. The duties of the Agent shall be administrative in nature. Subject to the provisions of Sections 9.1, 9.5 and 9.6, the Administrative Agent shall administer the Loans in the same manner as each administers its own loans. CONSULTATION WITH EXPERTS. As between the Administrative Agent on the one hand and the Banks on the other hand, the Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. LIABILITY OF ADMINISTRATIVE AGENT. As between the Administrative Agent on the one hand and the Banks on the other hand, the Administrative Agent, its affiliates nor any of its respective directors, officers, agents or employees shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of the Required Banks or (ii) in the absence of its own gross negligence or willful misconduct. As between the Administrative Agent on the one hand and the Banks on the other hand, the Administrative Agent and its directors, officers, agents, employees, or shareholders shall not be responsible for or have any duty to ascertain, inquire into or verify: (i) any statement, warranty or representation made in connection with this Agreement or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of the Borrower; (iii) the satisfaction of any condition specified in Article III, except receipt of items required to be delivered to such Administrative Agent; or (iv) the validity, effectiveness or genuineness of this Agreement, the other Loan Documents or any other instrument or writing furnished in connection herewith. As between the Administrative Agent on the one hand and the Banks on the other hand, no Administrative Agent shall incur any liability by acting in reliance upon any notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) believed by it to be genuine or to be signed by the proper party or parties. INDEMNIFICATION. Each Bank shall, ratably in accordance with its Commitment, indemnify the Administrative Agent and its affiliates and their respective directors, officers, agents, employees, shareholders and parent company (to the extent not reimbursed by the 69 Borrower) against any cost, expense (including, without limitation, counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitee's gross negligence or willful misconduct) that such indemnitee may suffer or incur in connection with its duties as Administrative Agent under this Agreement, the other Loan Documents or any action taken or omitted by such indemnitee hereunder. In the event that the Administrative Agent shall, subsequent to its receipt of indemnification payment(s) from Banks in accordance with this section, recoup any amount from the Borrower, or any other party liable therefor in connection with such indemnification, the Administrative Agent, as the case may be, shall reimburse the Banks which previously made the payment(s) pro rata, based upon the actual amounts which were theretofore paid by each Bank. The Administrative Agent shall reimburse such Banks so entitled to reimbursement within two (2) Business Days of its receipt of such funds from the Borrower or such other party liable therefor. CREDIT DECISION. Each Bank acknowledges that it has, independently and without reliance upon the Administrative Agent, the Documentation Agent, the Syndication Agent or any other Bank, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent, Documentation Agent, the Syndication Agent or any other Bank, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking any action under this Agreement. SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may resign at any time by giving notice thereof to the Banks, the Borrower and each other. Upon any such resignation, the Required Banks shall have the right to appoint a successor Administrative Agent, which successor Administrative Agent shall, provided no Event of Default has occurred and is then continuing, be subject to Borrower's approval, which approval shall not be unreasonably withheld or delayed (except that Borrower shall, in all events, be deemed to have approved Bank of America, N.A. or Citicorp North America, Inc., as a successor Administrative Agent). The Required Banks agree to appoint Bank of America, N.A. as Administrative Agent in the event Bank of America, N.A. and Citicorp North America, Inc. are at any point the only two parties remaining under consideration for such appointment. If no successor Administrative Agent shall have been so appointed by the Required Banks and approved by the Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Banks, appoint a successor Administrative Agent which shall be the Administrative Agent as the case may be, who shall act until the Required Banks shall appoint an Administrative Agent. Any appointment of a successor Administrative Agent by Required Banks or the retiring Administrative Agent pursuant to the preceding sentence shall, provided no Event of Default has occurred and is then continuing, be subject to the Borrower's approval, which approval shall not be unreasonably withheld or delayed. Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor Administrative Agent such successor Administrative Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Administrative Agent and the retiring Administrative Agent shall be released and discharged from its duties and obligations hereunder. After any retiring Administrative Agent's resignation hereunder, the provisions of this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Administrative Agent. For gross negligence or willful 70 misconduct, as determined by all the Banks (excluding for such determination Administrative Agent in its capacity as a Bank), Administrative Agent may be removed at any time by giving at least thirty (30) Business Days prior written notice to Borrower. Such resignation or removal shall take effect upon the acceptance of appointment by a successor Administrative Agent in accordance with the provisions of this Section 9.8. CONSENTS AND APPROVALS. All communications from Administrative Agent to the Banks requesting the Banks' determination, consent, approval or disapproval (i) shall be given in the form of a written notice to each Bank, (ii) shall be accompanied by a description of the matter or item as to which such determination, approval, consent or disapproval is requested, or shall advise each Bank where such matter or item may be inspected, or shall otherwise describe the matter or issue to be resolved, (iii) shall include, if reasonably requested by a Bank and to the extent not previously provided to such Bank, written materials and a summary of all oral information provided to Administrative Agent by Borrower in respect of the matter or issue to be resolved, and (iv) shall include Administrative Agent's recommended course of action or determination in respect thereof. Each Bank shall reply promptly, but in any event within ten (10) Business Days after receipt of the request therefor from Administrative Agent (the "Bank Reply Period"). Unless a Bank shall give written notice to Administrative Agent that it objects to the recommendation or determination of Administrative Agent (together with a written explanation of the reasons behind such objection) within the Bank Reply Period, such Bank shall be deemed to have approved of or consented to such recommendation or determination. With respect to decisions requiring the approval of the Required Banks or all the Banks, Administrative Agent shall submit its recommendation or determination for approval of or consent to such recommendation or determination to all Banks and upon receiving the required approval or consent shall follow the course of action or determination of the Required Banks or all the Banks (and each non-responding Bank shall be deemed to have concurred with such recommended course of action), as the case may be. CHANGE IN CIRCUMSTANCES BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR. If on or prior to the first day of any Interest Period for any Eurodollar Borrowing the Administrative Agent determines in good faith that deposits in dollars (in the applicable amounts) are not being offered in the relevant market for such Interest Period, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Banks, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make Eurodollar Loans shall be suspended. Unless the Borrower notifies the Administrative Agent at least two Business Days before the date of any Eurodollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as an Adjusted Base Rate Borrowing. ILLEGALITY. If, on or after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by any governmental authority, central 71 bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank (or its Eurodollar Lending Office) with any request or directive (whether or not having the force of law) made after the Closing Date of any such authority, central bank or comparable agency shall make it unlawful for any Bank (or its Eurodollar Lending Office) to make, maintain or fund its Eurodollar Loans, the Administrative Agent shall forthwith give notice thereof to the other Banks and the Borrower, whereupon until such Bank notifies the Borrower and the Administrative Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Bank to make Eurodollar Loans shall be suspended. With respect to Eurodollar Loans, before giving any notice to the Administrative Agent pursuant to this Section 10.2, such Bank shall designate a different Eurodollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank shall determine that it may not lawfully continue to maintain and fund any of its outstanding Eurodollar Loans to maturity and shall so specify in such notice, the Borrower shall be deemed to have delivered a Notice of Interest Rate Election and such Eurodollar Loan shall be converted as of such date to an Adjusted Base Rate Loan (without payment of any amounts that Borrower would otherwise be obligated to pay pursuant to Section 2.10 with respect to Loans converted pursuant to this Section 10.2) in an equal principal amount from such Bank (on which interest and principal shall be payable contemporaneously with the related Eurodollar Loans of the other Banks), and such Bank shall make such an Adjusted Base Rate Loan. If at any time, it shall be unlawful for any Bank to make, maintain or fund its Eurodollar Loans, the Borrower shall have the right, upon five (5) Business Day's notice to the Administrative Agent, to either (x) cause a lender, reasonably acceptable to the Administrative Agent, to offer to purchase the Commitments of such Bank for an amount equal to such Bank's outstanding Loans, and to become a Bank hereunder, or obtain the agreement of one or more existing Banks to offer to purchase the Commitments of such Bank for such amount, which offer such Bank is hereby required to accept, or (y) to repay in full all Loans then outstanding of such Bank, together with interest and all other amounts due thereon, upon which event, such Bank's Commitments shall be deemed to be canceled pursuant to Section 2.8(e). INCREASED COSTS. 1. If any Change in Law shall: (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Bank (except any such Eurodollar Reserve Percentage reflected in the LIBO Rate); or (ii) impose on any Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans or Adjusted Base Rate Loans made by such Bank; and the result of any of the foregoing shall be to increase the cost to such Bank of making or maintaining any Eurodollar Loan or Adjusted Base Rate Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Bank or to reduce the amount of any sum received or receivable by such Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Bank such additional amount or 72 amounts as will compensate such Bank for such additional costs incurred or reduction suffered. If any Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Bank's capital or on the capital of such Bank's holding company, if any, as a consequence of this Agreement or the Loans made by such Bank, to a level below that which such Bank or such Bank's holding company could have achieved but for such Change in Law (taking into consideration such Bank's policies and the policies of such Bank's holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Bank, as the case may be, such additional amount or amounts as will compensate such Bank or Banks holding company for any such reduction suffered. A certificate of a Bank setting forth the amount or amounts necessary to compensate such Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section 10.3 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof. Failure or delay on the part of any Bank to demand compensation pursuant to this Section 10.3 shall not constitute a waiver of such Bank's right to demand such compensation; PROVIDED that the Borrower shall not be required to compensate Bank pursuant to this Section for any increased costs or reductions incurred more than ninety (90) days prior to the date that such Bank notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Bank's intention to claim compensation therefor; PROVIDED FURTHER that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the ninety (90) day period referred to above shall be extended to include the period of retroactive effect thereof. The Borrower shall have no obligation to make any payments under this Section 10.3 to a Bank unless such Bank is generally imposing similar charges on its similarly situated borrowers. TAXES. (iii) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 10.4), the Administrative Agent, or Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. The Borrower shall indemnify the Administrative Agent and each Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Bank, as the case may be, on or with respect to any 73 payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 10.4) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability, delivered to the Borrower by a Bank, or by the Administrative Agent on its own behalf or on behalf of a Bank, shall be conclusive absent manifest error. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. Any Foreign Bank that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. If the Administrative Agent or a Bank determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 10.4, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 10.4 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Bank and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Bank in the event the Administrative Agent or such Bank is required to repay such refund to such Governmental Authority. This Section 10.4 shall not be construed to require the Administrative Agent or any Bank to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person. Notwithstanding anything to the contrary contained in this Section 10.4, the Borrower shall have no obligation to make any payments under this Section 10.4 to a Bank unless such Bank is generally imposing similar charges on its similarly situated borrowers. MITIGATION OBLIGATIONS; REPLACEMENT OF BANKS. (iv) If any Bank requests compensation under Section 10.3, or if the Borrower is required to pay any additional amount to any Bank or any Governmental Authority for the account of any Bank pursuant to Section 10.4, then such Bank shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its 74 offices, branches or affiliates, if, in the judgment of such Bank, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 10.3 or 10.4, as the case may be, in the future and (ii) would not subject such Bank to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Bank. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Bank in connection with any such designation or assignment. If any Bank requests compensation under Section 10.3, or if the Borrower is required to pay any additional amount to any Bank or any Governmental Authority for the account of any Bank pursuant to Section 10.4, or if any Bank defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Bank and the Administrative Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 11.4), all its interests, rights and obligations under this Agreement to an Assignee that shall assume such obligations (which Assignee may be another Bank, if a Bank accepts such assignment); PROVIDED that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, conditioned or delayed, (ii) such Bank shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the Assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 10.3 or payments required to be made pursuant to Section 10.4, such assignment will result in a reduction in such compensation or payments. A Bank shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Bank or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply. ADJUSTED BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURODOLLAR LOANS.

The Borrower shall indemnify the Administrative Agent, each Bank, and each Related Party of any of the foregoing Persons (each such Person being called an "INDEMNITEE") against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, including but not limited to the 399 Park Avenue Acquisition, (ii) any Loan or the use of 77 the proceeds therefrom or (iii) any environmental indemnity pursuant to Section 5.17, provided, however, that Borrower shall not be obligated under this Section 11.3(b) to indemnify any Indemnitee for liabilities arising from such Indemnitee's own gross negligence or willful misconduct. To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent under paragraph (a) or (b) of this Section 11.3, each Bank severally agrees to pay to the Administrative Agent such Bank's Pro Rata Share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; PROVIDED that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such. To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions or the use of the proceeds thereof. All amounts due under this Section 11.3 shall be payable promptly. SUCCESSORS AND ASSIGNS.

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants (to the extent provided in Section 11.4(c) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Banks) any legal or equitable right, remedy or claim under or by reason of this Agreement. (i) Subject to the conditions set forth below, any Bank may assign to one or more Financial Institutions (such party being an "Assignee") all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of: the Borrower, PROVIDED that no consent of the Borrower shall be required if an Event of Default has occurred and is continuing; and the Administrative Agent. Assignments shall be subject to the following additional conditions: 78 except in the case of an assignment of the entire remaining amount of the assigning Bank's Commitment or Loans, the amount of the Commitment or Loans of the assigning Bank subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 and shall be in multiples of $1,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, PROVIDED that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; each partial assignment shall be made as an assignment of a proportionate part of all the assigning Bank's rights and obligations under this Agreement, PROVIDED that this clause shall not be construed to prohibit the assignment of a proportionate part of all the assigning Bank's rights and obligations in respect of the Commitments or Loans; the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and the Assignee, if it shall not be a Bank, shall deliver to the Administrative Agent an Administrative Questionnaire.

Any assignment or transfer by a Bank of rights or obligations under this Agreement that does not comply with this Section 11.4 shall be treated for purposes of this Agreement as a sale by such Bank of a participation in such rights and obligations in accordance with this Section 11.4(c). The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Banks, and the Commitment of, and principal amount of the Loans owing to, each Bank pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Banks may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Bank, at any reasonable time and from time to time upon reasonable prior 79 notice, and upon written notice therefor, Administrative Agent shall deliver a copy of such Register to Borrower.

No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph. (i) Subject to the conditions set forth below, any Bank may sell participations to one or more banks or other entities (a "Participant") in all or a portion of such Bank's rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it) without the prior written consent of the Borrower and the Administrative Agent: (ii) Participations shall be subject to the following additional conditions: except in the case of an participation of the entire remaining amount of the assigning Bank's Commitment or Loans, the amount of the participation in the Commitment or Loans of the Bank sold subject to each such participation (determined as of the date the Assignment and Assumption with respect to such participation is delivered to the Administrative Agent) shall not be less than $5,000,000 and shall be in multiples of $1,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, PROVIDED that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing; such Bank's obligations under this Agreement shall remain unchanged; such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations; and the Borrower, the Administrative Agent and the other Banks shall continue to deal solely and directly with such Bank in connection with such Bank's rights and obligations under this Agreement.

Subject to Section 11.4(c)(ii), the Borrower agrees that each Participant shall be entitled to the 80 benefits of Sections 2.10, 10.3 and 10.4 to the same extent as if it were a Bank and had acquired its interest by assignment pursuant to Section 11.4(b). (iv) A Participant shall not be entitled to receive any greater payment under Section 10.3 or 10.4 than the applicable Bank would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower's prior written consent. A Participant that would be a Foreign Bank if it were a Bank shall not be entitled to the benefits of Section 10.4 unless the Borrower is notified of the participation sold to such Participant, such Participant agrees, for the benefit of the Borrower, to comply with Section 10.4 as though it were a Bank and Borrower consents to the same in writing. Any Bank may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Bank, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 11.4 shall not apply to any such pledge or assignment of a security interest; PROVIDED that no such pledge or assignment of a security interest shall release a Bank from any of its obligations hereunder or substitute any such pledgee or Assignee for such Bank as a party hereto.
