24 

delivers a second notice to Landlord, then the arbitrator appointed by Tenant shall be the arbitrator to determine the Expansion Space Fair Market Value for the Expansion Space in question.

(ii) If two arbitrators are chosen pursuant to Section 5(f)(i), the arbitrators so chosen shallmeet within 10 Business Days after the second arbitrator is appointed and shall seek to reach agreement on the Expansion Space Fair Market Value.

If they are unable to agree upon such appointment within 5 Business Days after expiration of such 20 Business Day period, thethird arbitrator shall be selected by the parties themselves. If the parties do not agree on the third arbitrator within 5 Business Days after expiration of the foregoing 5 Business Day period, then either party, on behalf of both, may requestappointment of such a qualified person by the American Arbitration Association (the “AAA”). If the AAA shall refuse to appoint such third arbitrator or fail to do so within 15 days of request, or if the AAA shall no longer be inexistence, either party hereto, on behalf of both, may apply to Judicial Arbitration & Mediation Services for the appointment of such third arbitrator and the other party shall not raise any objection as to JAMS’ full power andjurisdiction to entertain the application and make such appointment. The third arbitrator shall decide the dispute, if it has not been previously resolved, by following the procedures set forth in Section 5(f)(iii).

(iii) The Expansion Space Fair Market Value shall be fixed bythe third arbitrator in accordance with the following procedures. Concurrently with the appointment of the third arbitrator, each of the arbitrators selected by the parties shall state, in writing, his or her determination of the Expansion SpaceFair Market Value supported by the reasons therefor (and any prior discussions and/or offers by Landlord or Tenant (or their respective arbitrators) shall not be admissible as evidence or for any other purpose)). The third arbitrator shall have theright to consult experts and competent authorities for factual information or evidence pertaining to a determination of the Expansion Space Fair Market Value, but any such determination shall be made in the presence of both parties with full righton their part to cross-examine. The third arbitrator shall conduct such hearings and investigations as he or she deem appropriate and shall, within 30 days after being appointed, select which of the two proposed determinations most closelyapproximates his or her determination of the Expansion Space Fair Market Value. The third arbitrator shall have no right to propose a middle ground or any modification of either of the two proposed determinations. The determination the thirdarbitrator chooses as that most closely approximating his or her determination of the Expansion Space Fair Market Value shall constitute his or her decision and shall be final and binding upon the parties. The third arbitrator shall render thedecision in writing with counterpart copies to each party. The third arbitrator shall have no power to add to or modify the provisions of the Lease. Promptly following receipt of the third arbitrator’s decision, the parties shall enter into anamendment to the Lease evidencing the expansion of the Premises and confirming the fixed rent for the 

 
25 

Expansion Space in question, but the failure of the parties to do so shall not affect the effectiveness of the third arbitrator’s determination. 

(iv) In the event of a failure, refusal or inability of any arbitrator to act, his or her successor shall be appointed byhim or her, but in the case of the third arbitrator, his or her successor shall be appointed in the same manner as that set forth herein with respect to the appointment of the original third arbitrator. 

(g) Agreement of Terms. Landlord and Tenant, at either party’s request, shall promptly execute and exchange anappropriate agreement evidencing the leasing of any Expansion Space and the terms thereof in a form reasonably satisfactory to both parties, but no such agreement shall be necessary in order to make the provisions hereof effective.

36 

shall be determined by arbitration in accordance with the then prevailing Expedited Procedures of the Arbitration Rules for the Real Estate Industry of the American Arbitration Association or itssuccessor for arbitration of commercial disputes, except that the rules shall be modified as follows: 

(i)Within 10 Business Days following Tenant’s demand or deemed demand for arbitration, Tenant shall specify the name and address of the person to act as the arbitrator on Tenant’s behalf. The arbitrator shall be a real estate broker orappraiser with at least 10 years full-time commercial brokerage or appraisal experience who is familiar with the fair market value of office space in the Borough of Manhattan, City of New York, New York. Within 10 Business Days after the service ofthe demand for arbitration (or Tenant’s deemed demand for arbitration due to Tenant’s failure to respond within the above referenced 20 Business Day period), Landlord shall give notice to Tenant specifying the name and address of theperson designated by Landlord to act as arbitrator on its behalf, which arbitrator shall have qualifications similar to those required of Tenant’s arbitrator above. If Landlord fails to notify Tenant of the appointment of its arbitrator withinsuch 10 Business Day period, and such failure continues for 3 Business Days after Tenant delivers a second notice to Landlord, then the arbitrator appointed by Tenant shall be the arbitrator to determine the Fair Market Value for the RenewalPremises. 

(ii) If two arbitrators are chosen pursuant to Section 8(c)(i), the arbitrators sochosen shall meet within 10 Business Days after the second arbitrator is appointed and shall seek to reach agreement on Fair Market Value. If within 20 Business Days after the second arbitrator is appointed the two arbitrators are unable to reachagreement on Fair Market Value, then the two arbitrators shall appoint a third arbitrator, who shall be a competent and impartial (i.e., such person has not been associated or retained by either party in the past ten years) person withqualifications similar to those required of the first two arbitrators pursuant to Section 8(c)(i). If they are unable to agree upon such appointment within 5 Business Days after expiration of such 20 Business Day period, the thirdarbitrator shall be selected by the parties themselves. If the parties do not agree on the third arbitrator within 5 Business Days after expiration of the foregoing 5 Business Day period, then either party, on behalf of both, may request appointmentof such a qualified person by the AAA. If the AAA shall refuse to appoint such third arbitrator or fail to do so within 15 days of request, or if the AAA shall no longer be in existence, either party hereto, on behalf of both, may apply to JudicialArbitration & Mediation Services for the appointment of such third arbitrator and the other party shall not raise any objection as to the JAMS’ full power and jurisdiction to entertain the application and make such appointment. Thethird arbitrator shall decide the dispute, if it has not been previously resolved, by following the procedures set forth in Section 8(c)(iii). Each party shall pay the fees and expenses of its respective arbitrator and both shall sharethe fees and expenses of the third arbitrator. Attorneys’ fees and expenses of counsel and of witnesses for the respective parties shall be paid by the respective party engaging such counsel or calling such witnesses. 

(iii) The Fair Market Value in respect of each Renewal Term shall be fixed by the third arbitrator in accordance with thefollowing procedures. Concurrently with the appointment of the third arbitrator, each of the arbitrators selected by the parties shall state, in writing, his or her determination of the Fair Market Value supported by the reasons therefor (and anyprior discussions and/or offers by Landlord or Tenant (or their respective arbitrators) shall not be admissible as evidence or for any other purpose)). The third arbitrator shall have the right to consult experts and competent authorities for

 
37 

factual information or evidence pertaining to a determination of Fair Market Value, but any such determination shall be made in the presence of both parties with full right on their part tocross-examine. The third arbitrator shall conduct such hearings and investigations as he or she deem appropriate and shall, within 30 days after being appointed, select which of the two proposed determinations most closely approximates his or herdetermination of Fair Market Value. The third arbitrator shall have no right to propose a middle ground or any modification of either of the two proposed determinations. The determination he or she chooses as that most closely approximating his orher determination of the Fair Market Value shall constitute his or her decision and shall be final and binding upon the parties. The third arbitrator shall render the decision in writing with counterpart copies to each party. The third arbitratorshall have no power to add to or modify the provisions of the Lease. Promptly following receipt of the third arbitrator’s decision, the parties shall enter into an amendment to the Lease evidencing the extension of the term of the Lease for theRenewal Term in question and confirming the fixed rent for the Renewal Term in question, but the failure of the parties to do so shall not affect the effectiveness of the third arbitrator’s determination. 

(iv) In the event of a failure, refusal or inability of any arbitrator to act, his or her successor shall be appointed byhim or her, but in the case of the third arbitrator, his or her successor shall be appointed in the same manner as that set forth herein with respect to the appointment of the original third arbitrator.

If Tenant timely terminates the Lease with respect to such Offered Space, as aforesaid, then upon Landlord subsequently gaining possession of the Offered Space, Landlord shall promptly offer theapplicable Expansion Space to Tenant (a “OS Re-Offer Notice”) and Tenant shall have 30 days (or 15 days, if Landlord obtains possession of such Offered Space within 90 days after Tenant gives such cancellation notice) followingreceipt of such OS Re-Offer Notice (which shall not vary from the terms contained in the applicable Offered Space Notice) to notify Landlord it desires to lease the applicable Offered Space pursuant to the terms and conditions of thisSection 9. 

(h) If Tenant disputes Landlord’s determination of the Offered Space Fair MarketValue for any Offered Space pursuant to Section 9(a), Tenant shall give notice to Landlord of such dispute within 20 Business Days after delivery of the applicable Acceptance Notice (and if Tenant fails to timely give such notice, suchfailure shall be deemed to be an election by Tenant that it is disputing Landlord’s determination of the Offered Space Fair Market Value), and such dispute shall be determined by arbitration in accordance with the then prevailing ExpeditedProcedures of the Arbitration Rules for the Real Estate Industry of the American Arbitration Association or its successor for arbitration of commercial disputes, except that the rules shall be modified as follows: 

(i) Within 10 Business Days following Tenant’s demand or deemed demand for arbitration, Tenant shall specify the nameand address of the person to act as the arbitrator on Tenant’s behalf.

Within 10 Business Days after the service of the demand for arbitration (or Tenant’s deemed demand for arbitration due to Tenant’s failure torespond within the above referenced 20 Business Day period), Landlord shall give notice to Tenant specifying the name and address of the person designated by Landlord to act as arbitrator on its behalf, which arbitrator shall be similarly qualified.If Landlord fails to notify Tenant of the appointment of its arbitrator within such 10 Business Day period, and such failure continues for 3 Business Days after Tenant delivers a second notice to Landlord, then the arbitrator appointed by Tenantshall be the arbitrator to determine the Offered Space Fair Market Value for the Offered Space in question. 

(ii) If two arbitrators are chosen pursuant to Section 9(h)(i), the arbitrators so chosen shall meet within 10Business Days after the second arbitrator is appointed and shall seek to reach agreement on the Offered Space Fair Market Value. If within 20 Business Days after the second arbitrator is appointed the two arbitrators are unable to reach agreement onthe Offered Space Fair Market Value, then the two arbitrators shall appoint a third arbitrator, who shall be a competent and impartial (i.e., 

 
44 

such person has not been associated or retained by either party in the past ten years) person with qualifications similar to those required of the first two arbitrators pursuant toSection 9(h)(i). If they are unable to agree upon such appointment within 5 Business Days after expiration of such 20 Business Day period, the third arbitrator shall be selected by the parties themselves. If the parties do not agree onthe third arbitrator within 5 Business Days after expiration of the foregoing 5 Business Day period, then either party, on behalf of both, may request appointment of such a qualified person by the AAA. If the AAA shall refuse to appoint such thirdarbitrator or fail to do so within 15 days of request, or if the AAA shall no longer be in existence, either party hereto, on behalf of both, may apply to Judicial Arbitration & Mediation Services for the appointment of such thirdarbitrator and the other party shall not raise any objection as to the JAMS’ full power and jurisdiction to entertain the application and make such appointment. The third arbitrator shall decide the dispute, if it has not been previouslyresolved, by following the procedures set forth in Section 9(h)(iii).

The third arbitrator shall have the right to consult experts and competent authorities for factual information or evidence pertaining to a determination of the OfferedSpace Fair Market Value, but any such determination shall be made in the presence of both parties with full right on their part to cross-examine. The third arbitrator shall conduct such hearings and investigations as he or she deem appropriate andshall, within 30 days after being appointed, select which of the two proposed determinations most closely approximates his or her determination of the Offered Space Fair Market Value. The third arbitrator shall have no right to propose a middleground or any modification of either of the two proposed determinations. The determination the third arbitrator chooses as that most closely approximating his or her determination of the Offered Space Fair Market Value shall constitute his or herdecision and shall be final and binding upon the parties. The third arbitrator shall render the decision in writing with counterpart copies to each party. The third arbitrator shall have no power to add to or modify the provisions of the Lease.Promptly following receipt of the third arbitrator’s decision, the parties shall enter into an amendment to the Lease evidencing the expansion of the Premises and confirming the fixed rent for the Offered Space in question, but the failure ofthe parties to do so shall not affect the effectiveness of the third arbitrator’s determination. 

(iv) Inthe event of a failure, refusal or inability of any arbitrator to act, his or her successor shall be appointed by him or her, but in the case of the third arbitrator, his or her successor shall be appointed in the same manner as that set forthherein with respect to the appointment of the original third arbitrator. 

(i) In the event that (x) theexisting lease for any of the Offered Space is terminated prior to the expiration date specified therein as a result of a default thereunder and 

 
45 

Landlord has obtained legal possession of the Offered Space in question, or (y) Landlord receives a bona fide offer to lease Offered Space within two years prior to the Anticipated DeliveryDate in respect thereof, then Landlord may elect to accelerate the Offered Space Commencement Date with respect to such Offered Space (or any portion thereof) by giving immediate notice (an “Acceleration Notice”) of suchacceleration to Tenant by delivering an Offered Space Notice (without any obligation to comply with the notice provisions contained in Section 9(a)), specifying the date upon which Landlord anticipates that Landlord shall deliver suchOffered Space to Tenant (an “Accelerated Delivery Date”) provided, however, (1) in the case of clause (x) above, in no event shall the Anticipated Delivery Date be earlier than 90 days following the date the AcceptanceNotice is given by Tenant and (2) in the case of clause (y) above, in no event shall the Anticipated Delivery Date be earlier than 180 days following the date the Acceptance Notice is given to Landlord. In the event of such acceleration,Tenant shall have 30 days after delivery by Landlord of the Acceleration Notice within which to exercise its option to lease such Offered Space (time being of the essence with respect to the giving of the notice by Tenant).

(d) Tenant has inspected each portion of the Lower Level Premises and agrees (A) to accept possession of such portion of the Lower Level Premises in the “as is” condition existing as of thedate hereof, but broom-clean and Landlord shall legally demise the Lower Level Premises in accordance with Building-standard, provided that each portion of the Lower Level Premises shall be legally demised, (B) that neither Landlord norLandlord’s agents have made any representations or warranties with respect to the Lower Level Premises except as expressly set forth herein, and (C) except for Landlord’s Lower Level Asbestos Work (as hereinafter defined), Landlordhas no obligation to perform any work, supply any materials, incur any expense or make any alterations or improvements to any portion of the Lower Level Premises to prepare such portion of the Lower Level Premises for Tenant’s occupancy;provided, however, nothing contained herein shall eliminate or reduce or modify Landlord’s ongoing repair, maintenance and/or restoration obligations and Landlord’s obligations regarding the provision of services to the Lower LevelPremises, each to the extent provided for in this Amendment. Tenant’s occupancy of any part of a portion of the Lower Level Premises shall be conclusive evidence, as against Tenant, that Tenant has accepted possession of such portion of theLower Level Premises in its then current condition. 

(e) (i) Tenant shall have the right to use the electriccapacity currently serving the Lower Level Premises for the intended uses thereof specified herein and Landlord agrees to provide such capacity for such intended uses. Tenant’s use of electricity in the Lower Level Premises shall not exceed thecapacity of the existing feeders to the Building or the risers or wiring installations therein, and Tenant shall not use any electrical equipment which, in Landlord’s sole judgment, shall overload such installations or interfere with the usethereof by tenants and other occupants in the Building. 

(ii) An estimated charge for such electricity of $1.88per rentable square foot (the “Electrical Inclusion Factor”) is included in the fixed rent of the Lower Level Premises on a so-called “rent inclusion” basis; however, the value to Tenant of such service may not be fullyreflected in the fixed rent. Accordingly, Tenant agrees that following one year after the commencement of Tenant’s ordinary business activities in the Lower Level Premises, Landlord may cause an independent electrical engineer or electricalconsulting firm selected by Landlord (“Landlord’s Consultant”) to make a determination, certified in writing to Landlord and Tenant, of the full cost of the electrical service supplied to Tenant, based upon a survey indicatingthe lighting load, office equipment and all other electrical usage by Tenant. Thereafter, Landlord may, at any time and from time to time, at its sole option, cause Landlord’s Consultant to make subsequent determinations of the then full costof the electrical service supplied to Tenant on the basis set forth in the immediately preceding sentence. If Landlord’s 

 
50 

Consultant determines that the full cost of the electrical service supplied to the Lower Level Premises exceeds the Electrical Inclusion Factor, as increased from time to time in accordance withthis Section 11(e), then, upon notice to Tenant, the fixed rent and the Electrical Inclusion Factor in respect of the Lower Level Premises shall be increased by the percentage increase in such usage over the prior usage as determined byLandlord’s Consultant. Any increase in fixed rent and the Electrical Inclusion Factor in respect of the Lower Level Premises shall be effective as of the date of the increase in Tenant’s electrical usage, as determined by the survey, andTenant’s liability therefor shall be retroactive to such date. The computation of the Electrical Inclusion Factor under this Section 11(e) is intended to constitute a formula for an agreed rental adjustment and may or may notconstitute an actual reimbursement to Landlord for the electrical service supplied to the Lower Level Premises pursuant to the Lease. If any tax is imposed on Landlord’s receipts or income from the redistribution, furnishing, or sale ofelectricity to Tenant as provided for above (other than a general tax on corporate income not specific to the provision of electricity), whether based on the Electrical Inclusion Factor or any increase therein provided for above, or otherwise,Tenant shall reimburse Landlord for such tax, if and to the extent permitted by law. Notwithstanding any provision of the Lease to the contrary, Tenant shall pay to Landlord the Electrical Inclusion Factor (which is included in fixed rent) from andafter the Lower Level Commencement Date in respect of each portion of the Lower Level Premises even if fixed rent (other than the Electrical Inclusion Factor) is not otherwise payable hereunder until the Lower Level Premises Rent Commencement Datein respect thereof, which payment shall be made at the same time and in the same manner as fixed rent (whether or not then payable). 

(iii) Wherever in this Section 11(e) Landlord is given the right to cause Landlord’s Consultant to make a determination of the full cost of the annual electric services supplied to Tenantto the Lower Level Premises, Tenant shall have the right (i) to dispute such determination by notice delivered to Landlord within 20 days after notice to Tenant of such determination (time being of the essence as to such date), and (ii) todesignate in such notice an independent electrical engineer or electrical consulting firm (“Tenant’s Consultant”) to make, at Tenant’s sole cost and expense, a determination of Tenant’s electrical usage at the LowerLevel Premises, using the same method used by Landlord’s Consultant as set forth in Section 11(e)(i). If Tenant’s Consultant determines that Tenant’s electrical usage at the Lower Level Premises is less than thatdetermined by Landlord’s Consultant (or if Tenant’s Consultant otherwise disputes the conclusions of Landlord’s Consultant) and such consultants are unable to reach agreement within 10 days following notice to Landlord of thedetermination by Tenant’s Consultant, then Landlord’s Consultant and Tenant’s Consultant shall jointly appoint a third electrical engineer or consulting firm to conduct a survey to determine Tenant’s electrical usage. Thedetermination by such third electrical engineer or consulting firm shall be final and the costs of such determination shall be borne by the unsuccessful party (and if both parties are partially successful, the third electrical engineer shallapportion the costs between the parties based on the degree of success of each party). Pending such final determination, Tenant shall pay to Landlord the Electrical Inclusion Factor determined by Landlord’s Consultant. Following a finaldetermination pursuant to the terms hereof, Tenant shall pay to Landlord the amount of any underpayment by Tenant, or Landlord shall credit to Tenant the amount of any overpayment by Tenant. If Tenant shall fail to dispute the initial determinationof Landlord’s Consultant within the above-described 20-day period, then such determination shall be deemed to be final and binding on Landlord and Tenant. 

****(iv) If Landlord’s cost of electricity increases or decreases after the Lower Level Commencement Date in respect of a portion of the Lower Level Premises for any reason whatsoever, then theElectrical Inclusion Factor shall be increased or decreased, as the case may be, in the same percentage for the remainder of the term of the Lease. Landlord shall 

 
51 

notify Tenant of any such changes and any such increase or decrease in fixed rent applicable to the Lower Level Premises and the Electrical Inclusion Factor shall be effective as of the date ofsuch increase or decrease in Landlord’s cost of electricity, and Tenant’s liability therefor shall be retroactive to such date. Notwithstanding anything set forth herein to the contrary, the Electrical Inclusion Factor shall in no event bedecreased below the amount set forth in above. 

(v) Landlord shall provide ventilation to the Lobby Premisesand to the Basement Premises through the Building systems currently providing such ventilation. Landlord shall have no obligation to provide any services to either portion of the Lower Level Premises, except as provided above, cleaning service inaccordance with the terms of the Lease and elevator service.

(f) If, following the Lower Level Premises Commencement Date, Tenant (together with its Affiliates and Permitted Users)fails to occupy at least 100,000 rentable square feet in the Building (which occupancy test shall be deemed satisfied so long as Tenant is not subletting at least 100,000 rentable square feet to non-Affiliates or other unrelated thirdparties)**,** Landlord may terminate Tenant’s right to lease the Lobby Premises. Upon notice of termination by Landlord, the Lease in respect of the Lobby Premises shall come to an end and expire on the date which is 60 days after the givingof such notice, with the same force and effect as if said date were the Extended Expiration Date set forth in this Amendment in respect of the Lobby Premises, unless sooner terminated pursuant to any other term, covenant or condition of this Leaseor pursuant to law, unless prior to the expiration of said 60 days, Tenant (together with its Affiliates and Permitted Users) satisfies the above occupancy test. 

(g) Landlord shall use the Lobby Premises as a reception area for its invitees and for security and for no other purpose.Landlord shall use the Basement Premises for a mailroom, staging renovations to its space, Tenant’s security services and storage and for no other purpose.

AGREEMENT 

For mutual consideration, including the mutual covenants and agreements set forth below, the receipt and sufficiency of which are herebyacknowledged, the parties hereto agree as follows: 

1. Tenant agrees that the Lease is and shall be subject and subordinate tothe Security Documents and to all present or future advances under the obligations secured thereby and all renewals, amendments, modifications, consolidations, replacements and extensions of the secured obligations and the Security Documents, to thefull extent of all amounts secured by the Security Documents from time to time. Said subordination is to have the same force and effect as if the Security Documents and such renewals, modifications, consolidations, replacements and extensionsthereof had been executed, acknowledged, delivered and recorded prior to the Lease, any amendments or modifications thereof and any notice thereof. The provisions of this Section 1 to the effect that the Lease shall be “subject” tothe Security Documents are intended to ensure the priority of the Security Documents over the Lease, but are not otherwise intended to deprive Tenant of any of its rights under the Lease, except as provided in this Agreement (e.g., any current orfuture provision of the Security Documents restricting the use of the Premises would not be binding upon Tenant if and to the extent that any such provision would diminish the rights of Tenant with respect to the use of the Premises as set forth inthe Lease). 

2. Lender agrees that, if the Lender exercises any of its rights under the Security Documents, including an entryby Lender pursuant to the Mortgage or a foreclosure of the Mortgage, or if Lender acquires the Property by deed-in-lieu of foreclosure, Lender shall not disturb Tenant’s rights of possession, use and quiet enjoyment of the Premises under theterms of the Lease, so long as Tenant is not in default beyond the expiration of any applicable notice and grace period of any term, covenant or condition of the Lease. 

3. Tenant agrees that, in the event of a foreclosure of the Mortgage by Lender or the acceptance of a deed in lieu of foreclosure by Lender or any other succession of Lender to fee ownership, Tenant willattorn to and recognize Lender as its landlord (and Lender will accept such attornment and recognize Tenant as its tenant) under the Lease for the remainder of the term of the Lease (including all extension periods which have been or are hereafterexercised) upon the same terms and conditions as are set forth in the Lease (subject to the terms of this Agreement), and Tenant hereby agrees to pay and perform all of the obligations of Tenant pursuant to the Lease subject to Tenant’s rightsand remedies thereunder, as same may be limited by the terms of this Agreement. 

4. Upon such attornment, the Lease shallcontinue as a direct lease between Lender and Tenant upon all the terms and conditions thereof, except that Tenant agrees that, in the event Lender succeeds to the interest of Landlord under the Lease, Lender shall not be: 

(a) subject to the provisions of Sections 4(b) and 4(d) hereof, liable for any act or omission of any prior Landlord(including, without limitation, the then defaulting Landlord), except to the extent that (1) such act or omission constitutes a non-monetary default by 

 
2 

Landlord under the Lease and continues after the date of attornment, (2) Lender receives notice thereof in accordance with Section 9 hereof and (3) Lender’s liability islimited to the effects of the continuation of such default after such date of attornment and shall not include any liability of any prior Landlord (including, without limitation, the then defaulting Landlord) which accrued prior to such date ofattornment, or 

(b) subject to any defense or offsets which Tenant may have against any prior Landlord(including, without limitation, the then defaulting Landlord), other than with respect to the right of offset relating to “Landlord’s Extension Contribution” (as defined in the 4th Amendment) as expressly set forth inSection 7(c) of the 4th Amendment; provided, however, that Lender shall be subject to such defenses expressly provided in the Lease which have first accrued against Lender after it succeeds to the interest of Landlord under theLease, including any relating to the failure of Lender to perform maintenance and repair of the Property to the extent required under the Lease. Notwithstanding the foregoing provisions of this Section 4(b) and anything contained in thisAgreement to the contrary, in the event Lender succeeds to the interest of Landlord under the Lease, Lender shall not be subject to any abatement, defense or offsets relating to any obligation of Landlord to perform the “Extension Work”and/or the “Expansion Extension Work” (as such terms are defined in the Fourth Amendment) or any other tenant improvement work or tenant improvement allowance (other than with respect to Landlord’s Extension Contribution as set forthabove) or any other work required to be performed by Landlord in connection with the delivery of the Premises or any portion thereof, whether such abatement, defense or offsets for the Extension Work, Expansion Extension Work or other work firstaccrued before or after Lender succeeds to the interest of Landlord under the Lease other than the abatement of rent and/or extension of “free rent” period remedies (the “Additional Abatement”) expressly set forth in the4th Amendment relating to the failure by Landlord to perform on a timely basis the Extension Work and/or the Expansion Extension Work or to deliver all or any portion of the Premises and/or the Temporary Space within the time periods set forth inthe 4th Amendment, or 

(c) bound by any payment of rent or additional rent which Tenant might have paid formore than one month in advance of the due date under the Lease to any prior Landlord (including, without limitation, the then defaulting Landlord), except if such prepayment is expressly required under the terms of the Lease for payment of estimatedoperating expenses and real estate taxes, or 

(d) bound by any obligation to (i) make any payment toTenant which was required to be made prior to the time Lender succeeded to any prior Landlord’s interest or, subject to Section 4(b) above, which relate to any acts or omission of any prior Landlord, (ii) make any payment at any timerelating to any work allowance or contribution required to be made by Landlord to Tenant or (iii) perform the Extension Work and/or the Expansion Extension Work or any other tenant improvement work or any other work required to be performed byLandlord in connection with the Premises or any portion thereof (other than any obligations of Landlord relating to compliance with law, repair or maintenance, restoration after a casualty or condemnation; provided, however, that this clause(d) is not intended to modify any of tenant’s rights as set forth in Section 4(b) hereof, or 

(e) accountable for any monies deposited with any prior Landlord (including security deposits), except to the extent suchmonies are actually received by Lender, or 

(f) bound by any surrender, termination, amendment or modificationof the Lease made without the consent of Lender, provided, however, Lender’s consent shall not be 

 
3 

required in connection with any surrender, termination, amendment or modification of the Lease which merely evidences Tenant’s exercise of any unilateral right or option Tenant may expresslyhave under the Lease which does not requires Landlord’s consent or the exercise of any right of termination which Tenant may have at law subject, however, in all events to the other provisions in this Section 4 and the terms ofSection 6 hereof. 

5. Tenant agrees that, notwithstanding any provision hereof to the contrary, the terms of the Mortgageshall continue to govern with respect to the disposition of any insurance proceeds or eminent domain awards, and any obligations of Landlord to restore the real estate of which the Premises are a part shall, insofar as they apply to Lender, belimited to insurance proceeds or eminent domain awards received by Lender after the deduction of all costs and expenses incurred in obtaining such proceeds or awards; provided, however, that nothing contained in this Section 5shall be deemed to diminish or otherwise modify the rights of Tenant expressly set forth in the Lease with respect to abatement of rent and the termination rights set forth therein relating to casualty or condemnation in the event that the realestate of which the Premises are a part are not restored in accordance with, and within the time periods set forth in, the Lease. 

6. Tenant hereby agrees to give to Lender copies of all notices of Landlord default(s) under the Lease in the same manner as, and whenever, Tenant shall give any such notice of default to Landlord, and nosuch notice of default shall be deemed given to Landlord unless and until a copy of such notice shall have been so delivered to Lender. In addition to and not in limitation of the foregoing, Tenant shall give notice to Lender of any failure byLandlord to timely fund in accordance with the terms of the 4th Amendment any portion of Landlord’s Extension Contribution and such notice shall be given by Tenant not less ten (10) days before Tenant exercises any right of offset inconnection therewith. Furthermore, Tenant shall use its good faith efforts to give notice to Lender of any failure by Landlord to timely complete the Extension Work and/or Expansion Extension Work or to deliver all or any portion of the Premisesand/or the Temporary Space within the time periods set forth in the Fourth Amendment (each, a “Failure to Timely Deliver”), within ten (10) days after (i) any additional rent abatement period or the extension of any rentabatement period is triggered under the Lease or (ii) the right, if any, of Tenant to terminate the Lease or any portion thereof has been triggered under the 4th Amendment as a result of a Failure to Timely Deliver. The notice in the foregoingsentence shall indicate the specific floors which were not timely delivered and the date by which such floors were required to be delivered under the terms of the Lease. Subject to the terms of this Agreement, Lender shall have the right to remedyany Landlord default under the Lease, or to cause any default of Landlord under the Lease to be remedied, and for such purpose Tenant hereby grants Lender such additional period of time as may be reasonable to enable Lender to remedy, or cause to beremedied, any such default in addition to the period given to Landlord for remedying, or causing to be remedied, any such default. Tenant shall accept performance by Lender of any term, covenant, condition or agreement to be performed by Landlordunder the Lease with the same force and effect as though performed by Landlord. In addition, no Landlord default under the Lease shall entitle Tenant to terminate the Lease or (other than as set forth in Section 5(e) of the Lease relating toonly those floors in the Expansion Space (as defined in the Fourth Amendment) where Landlord has failed to timely deliver vacant possession of the applicable space to Tenant) to offset any amounts against the rent due thereunder: (i) as long asLender, in good faith, shall have commenced to cure such default within the above referenced time period and shall be prosecuting the same to completion with reasonable diligence, subject to force majeure, or (ii) if possession of the Premisesis required in order to cure such default, or if such default is not susceptible of being cured by Lender, as long as Lender, in good faith, shall have notified Tenant that Lender intends to institute proceedings

 
4 

under the Security Documents, and, thereafter, as long as such proceedings shall have been instituted and shall be prosecuted with reasonable diligence; provided, however, in no event shall suchadditional cure period exceed one hundred twenty (120) days after notice is given to Lender if such default is then materially and adversely affecting Tenant’s use and operations in the Premises. Lender shall have the right, withoutTenant’s consent, to foreclose the Security Instrument or to accept a deed in lieu of foreclosure of the Security Instrument or to exercise any other remedies under the Security Documents.

Tenant agrees that upon receipt of a written notice from Lender of adefault by Landlord under the Loan, Tenant will thereafter, if requested by Lender, pay rent to Lender in accordance with the terms of the Lease. Tenant shall have no responsibility to ascertain whether such notice by Lender is permitted under theSecurity Documents, or to inquire into the existence of an event of default.
