Failure to Give Possession: 24. If Owner is unable to give possession of the demised premises on the date of the commencement of the term hereof because of the holding-over or retention of possession of any tenant, undertenant or occupants, or if the demised premises are located in a building being constructed, because such building has not been sufficiently completed to make the demised premises ready for occupancy, or because of the fact that a certificate of occupancy has not been procured, or for any other reason, Owner shall not be subject to any liability for failure to give possession on said date and the validity of the lease shall not be impaired under such circumstances, nor shall the same be construed in any wise to extend the term of this lease, but the rent payable hereunder shall be abated (provided Tenant is not responsible for Owner’s inability to obtain possession or complete construction) until after Owner shall have given Tenant written notice that the Owner is able to deliver possession in condition required by this lease.

No payment by Tenant or receipt by Owner of a lesser amount than the monthly rent herein stipulated shall be deemed to be other than on account of the earliest stipulated rent, nor shall any endorsement or statement of any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Owner may accept such check or payment without prejudice to Owner’s right to recover the balance of such rent or pursue any other remedy in this lease provided. No act or thing done by Owner or Owner’s agents during the term hereby demised shall be deemed an acceptance of a surrender of the demised premises, and no agreement to accept such surrender shall be valid unless in writing signed by Owner. No employee of Owner or Owner’s agent shall have any power to accept the keys of said premises prior to the termination of the lease, and the delivery of keys to any such agent or employee shall not operate as a termination of the lease or a surrender of the demised premises.

Waiver of Trial by Jury: 26. It is mutually agreed by and between Owner and Tenant that the respective parties hereto shall, and they hereby do, waive trial by jury in any action proceeding or counterclaim brought by either of the parties hereto against the other (except for personal injury or property damage) on any matters whatsoever arising out of, or in any way connected with, this lease, the relationship of Owner and Tenant, Tenant’s use of, or occupancy of, the demised premises, and any emergency statutory or any other statutory remedy..

If Owner shall eliminate and/or reduce the payment of any of the items includible in Operating Expenses as a result of the installation of labor-saving devices, or by other means, then, and in such event, in computing the additional rent payable under this Article, the cost of such labor-saving devices or other means shall be included in Operating Expenses whether or not they would otherwise be includible hereunder.

(b) Tenant shall, during the Term, pay to Owner as additional rent at the times hereinafter specified an amount (the “Operating Payment”) equal to Tenant’s Proportionate Share of the Operating Expenses for the then current Lease Year or calendar year (as the case may be) that are in excess of the Operating Expenses for the Operating Base Year (as set forth in the Basic Lease Provisions).

(c) If, at any time during the Term in respect of which an Operating Payment is due hereunder, more than five percent (5%) of the rentable space in the Building shall be vacant or unoccupied, Operating Expenses for such period shall be adjusted to reflect Operating Expenses that would have been incurred if ninety-five percent (95%) of the rentable space in the Building had been occupied.

(d) Owner may furnish to Tenant, prior to the commencement of each Lease Year a written statement setting forth Owner’s reasonable estimate of the Operating Payment for such Lease Year (an “Operating Estimate”). From and after the Commencement Date, Tenant shall pay to Owner on the first day of each month during the Lease Year in respect of which the Operating Payment will be due, an amount equal to one-twelfth (1/12th) of the Operating Estimate for such Lease Year. If, for any reason, Owner shall not furnish to Tenant an Operating Estimate for any Lease Year or if Owner shall furnish an Operating Estimate for a Lease Year subsequent to the commencement thereof, then: (i) until the first day of the month following the month in which such Operating Estimate is furnished to Tenant, Tenant shall pay to Owner on the first day of each month an amount equal to 105% of the monthly sum payable by Tenant to Owner under this Paragraph (d) in respect of the last month of the preceding Lease Year; (ii) within ten (10) days after such Operating Estimate is furnished to Tenant, Tenant shall, if there shall be a deficiency in the installments of the Operating Payment theretofore paid for such Lease Year, pay the full amount thereof or, if there shall have been an overpayment, be entitled to request that Owner refund the amount thereof to Tenant; and (iii) on the first day of the month following the month in which such Operating Estimate is furnished to Tenant and monthly thereafter throughout the remainder of such Lease Year Tenant shall pay to Owner an amount equal to one-twelfth (1/12th) of the Operating Payment shown on such Operating Estimate. Owner may, at any time during any Lease Year, furnish to Tenant a revised Operating Estimate for such Lease Year, and in such case, the Operating Payment for such Lease Year shall be adjusted and paid or refunded or credited as the case may be, substantially in the same manner as provided in the preceding sentence.

(e) Owner shall furnish to Tenant a statement or statements setting forth the Operating Payment (an “Owner’s Statement”) for each Lease Year. The statement of Operating Expenses set forth in an Owner’s Statement shall be deemed binding upon Tenant and determined by Tenant to be correct in all respects if, within ninety days after its receipt of same, Tenant fails to notify Owner, in writing, that it disputes such bills, invoices or statements. If an Owner’s Statement shall show that the sums paid by Tenant, if any, under Paragraph (d) of this Article exceeded the Operating Payment to be paid by Tenant for the Lease Year for which such Owner’s Statement is furnished, Owner shall refund to Tenant the amount of such excess and if Owner’s Statement for such Lease Year shall show that the sums so paid by Tenant were less than the Operating Payment to be paid by Tenant for such Lease Year, Tenant shall pay the amount of such deficiency within ten (10) days after its receipt of such Owner’s Statement. Owner shall endeavor to furnish to Tenant an Owner’s Statement within one hundred eighty (180) days after each Lease Year but Owner’s failure to render or delay in rendering an Owner’s Statement with respect to any Lease Year or any component of the Operating Payment shall not prejudice Owner’s right to thereafter render an Owner’s Statement with respect to any such Lease Year or such component, and the rendering of an Owner’s Statement for any Lease Year shall not prejudice Owner’s right to thereafter render a corrected Owner’s Statement for such Lease Year.

(f) In any case provided in this lease in which Tenant is entitled to a refund, Owner may, in lieu of allowing such refund, credit against future installments of additional rent any amounts to which Tenant shall be entitled. If this lease shall expire before any such credit shall have been fully applied, then (provided Tenant has not defaulted hereunder) Owner shall refund to Tenant the unapplied balance of such credit. Nothing contained in this Article or in Article 37 hereof shall be construed to decrease the amount of Base Rent reserved hereby and in no event and under no circumstances shall Tenant be entitled to set off against or deduct from the Base Rent herein reserved any additional rent or other sums payable to or for the benefit of Owner or otherwise.

(g) The expiration or termination of this lease shall not affect the rights or obligations of the parties hereto respecting any payments due hereunder and any statement or bill relating to such payment may be sent to Tenant subsequent to, and all such rights and obligations shall survive, any such expiration or termination.]

39. Electricity; Air Conditioning:

(a) Tenant shall obtain electricity for all of Tenant’s electrical needs for the demised premises including, but not limited to, the heating, ventilation and air conditioning system serving the demised premises, on a “rent inclusion” basis (i.e., there shall be no separate charge to Tenant for such electricity by way of measuring the same on any meter or otherwise). The cost of furnishing electricity to Tenant for the demised premises shall be included in the Base Rent reserved hereunder as estimated in this Paragraph, subject, however, to all of the other provisions of this Article. Initially, an estimate in the amount of the ERI Sum (as set forth in the Basic Lease Provisions) has been included in the Base Rent as the annual charge for Owner’s service of furnishing electricity to the demised premises on a “rent inclusion” basis (such amount, as the same may be increased pursuant to any of the provisions of this Article, being hereinafter referred to as the “rent inclusion factor”) for use during normal business hours of 8:00 a.m. to 6:00 p.m., Mondays through Fridays, excluding holidays. At any time after Tenant takes possession of the demised premises Owner may cause a survey to be prepared by a reputable, independent electrical consultant to be selected by Owner, the cost of which survey shall be borne equally by Owner and Tenant. The purpose of said survey shall be to determine the appropriate charge to Tenant for electricity to be included in Base Rent taking into account the full electric service including the estimated demand based upon the connected load necessary or useful for Tenant’s operation of all equipment, lighting and other installations, including, without limitation, air conditioning, heating and ventilation and any additional hours in excess of normal business hours during which the demised premises are in use. The rent inclusion factor shall, from time to time, be determined on the basis of Service Classification under which Owner purchases electricity for the Building inclusive of all applicable “demand,” “fuel adjustment” and any other charges and any taxes included in or applicable to such rates. When the charge for the electricity has been so determined as a result of such survey, the Base Rent shall be increased by the difference between the charge per annum determined by the survey and the estimated rent inclusion factor, effective as of the date of the survey.

(b) Tenant’s installations and its use of electricity in the demised premises shall not at any time exceed: (i) five (5) watts (connected load at the panel) per rentable square foot; or (ii) the capacity of existing feeders, risers and wiring serving the Building and the demised premises. In order to ensure that such capacity is not exceeded and to avert a possible adverse effect upon the Building electric service, Tenant shall not, without Owner’s prior written consent in each instance, connect any additional fixtures, appliances or equipment (other than lamps, fractional horsepower appliances and similar items of customary office equipment of small power consumption) to the Building electric distribution system or make any alteration or addition to the electric system of the demised premises existing as of the Commencement Date. Should Owner grant such consent, all additional risers or other equipment required therefor shall be installed by Owner at Tenant’s sole cost and expense, payable as additional rent upon demand. As a condition to granting such consent, Owner may require that Tenant agree to an increase in the Base Rent by an amount which will reflect the additional service to be furnished by Owner, that is, the potential electric energy (connected load) to be made available to Tenant based upon the estimated additional capacity of such additional risers or other equipment. Such increases shall be determined on the basis of the value of furnishing and installing any additional equipment or electrical facilities.

(c) If Tenant shall require electricity beyond the normal business hours specified above or for purposes other than as specified in Paragraphs (a) and (b) of this Article, or if the rate schedule of the company supplying electricity to the Building, including any supplementary charges such as “fuel adjustments,” “time of day charges” or any other charges for the supply of electricity to the Building shall be increased or imposed subsequent to the date of this lease, or if Tenant’s failure to maintain its machinery and equipment in good order and repair causes greater consumption of electricity, the Base Rent shall be adjusted to reflect the resulting increases in Owner’s cost in providing electricity to the demised premises, and the rent inclusion factor shall also be adjusted accordingly. Tenant has reviewed the electrical capacity available to the demised premises and represents to and for the benefit of Owner that it is satisfied therewith.

(d) Owner shall have the right to discontinue the furnishing of electricity upon not less than sixty (60) days prior written notice to Tenant. If Owner exercises such right, this lease shall continue in full force and effect and shall be unaffected thereby, except that from and after the effective date of such discontinuance, Owner shall not be obligated to furnish electricity to Tenant. If Owner so discontinues furnishing electricity to Tenant, Tenant shall arrange to obtain electricity directly from the public utility or other company furnishing electricity to the Building as expeditiously as is possible and shall thereafter pay Owner for maintaining the current transformers, service switches, feeders, risers, panels, wiring, etc. serving the demised premises. In the event any additional meters, transformers, service switches, panel boards, feeders, risers, conduit, wiring and/or other conductors and equipment may be required in order to enable Tenant to obtain electricity directly from such public utility or such other company, they shall be installed by Owner and the cost thereof shall be paid by Tenant, as additional rent, upon Owner’s demand.]

(e) Owner shall not in any way be liable or responsible to Tenant for any loss, damage or expense which Tenant may sustain or incur if: (i) the supply of electricity to the demised premises is interrupted, unless such loss, damage or expense is caused by Owner’s gross negligence or willful misconduct, in which case Owner’s sole liability shall be to promptly repair such failure or defect; (i) the quantity or character of electricity is changed or is no longer available or suitable for

Tenant’s requirements; or (iii) Tenant objects to, is inconvenienced by or otherwise affected by any requirement of the public utility or other company serving the Building. Tenant will comply with the general rules, regulations, terms, conditions and requirements of the public utility or other company supplying electricity to the Building that may now or hereafter be applicable thereto. Tenant shall enter into such modifications of this lease as Owner may from time to time request in connection with any requirement of any public utility (or other company supplying electricity to the Building) or any requirement of law pertaining to electrical consumption or service, or charges therefor.

(f) At Owner’s option, Owner shall maintain all lighting fixtures and furnish and install all lighting tubes, lamps, ballast transformers, starters and bulbs in the demised premises and Tenant shall pay, promptly upon demand, Owner’s reasonable charges therefor.

(g) Owner shall furnish condenser water to the air handling system heretofore installed by Owner for the demised premises on business days from 8:00 a.m. to 6:00 p.m. between May 15 and September 15 of each year during the Term in quantities reasonably determined by Owner to be adequate (“Building Standard Quantities”) for the operation of such air handling system. Tenant hereby agrees to reimburse Owner, as additional rent, within ten (10) days after demand for 17.87% of the cost incurred by Owner (but in no event more than $2,500.00 per year), to maintain and keep in good order, condition and repair the air handling system and all other air conditioning equipment now or at any time serving the 21st floor in the Building. The current standard Building charge for condenser water is $2,000 per ton, but is subject to increase by Owner from time to time. The cost of any condenser water required by Tenant in excess of Building Standard Quantities shall be paid by Tenant to Owner from time to time as additional rent, within ten (10) days after demand therefor, at the then Building-wide charges established by Owner, which charge is currently $50 per hour, but is subject to increase by Owner from time to time, for additional condenser water provided to office tenants of the Building as long as Owner’s provision of such additional condenser water to Tenant shall not cause a disproportionate allocation of the quantity of condenser water then available in the Building. Owner, throughout the Term, shall have free and unrestricted access to all air conditioning equipment and facilities in and/or serving the demised premises and Owner reserves the right to interrupt, curtail, stop or suspend the supply of condenser water when necessary by reason of accident or for repairs, alterations or improvements which are, in the judgment of Owner, desirable or necessary to be made, or by reason of the difficulty or unavailability in securing supplies or labor, strikes, or for any other causes beyond Owner’s control, whether such other causes be similar or dissimilar to those hereinabove specifically mentioned. Furthermore, Owner reserves the right, at any time throughout the Term, to modify, change, reconstruct or alter the air conditioning system or any portion thereof, and the risers, pipes, ducts and conduits used in connection therewith, without affecting the obligations of Tenant hereunder or incurring any liability to Tenant therefor.

(h) Intentionally omitted.

(i) Any use of the demised premises, or any part thereof in a manner exceeding the design conditions thereof (including, without limitation human occupancy factors and connected electrical load), or rearrangement of partitioning in a manner that interferes with normal operation of the heat and air-conditioning systems (hereinafter called the “systems”) serving the same, or the use of machinery and equipment, including without limitation, computer and data processing machines, may require changes in such systems. Such changes, so occasioned, shall be made by Tenant, at its expense, subject to Owner’s prior written approval of such changes, which approval shall not be unreasonably withheld. Tenant shall not make any change, alteration or addition to or substitution of components of the systems without Owner’s prior written approval, which shall not be unreasonably withheld.

40. Subordination and Attornment:

(a) Tenant hereby acknowledges and agrees that Owner has advised it that as of the date hereof: (i) Owner does not own the Building or the Land but leases same from The Carnegie Hall Corporation (“CHC”) pursuant to a lease (the “Building Lease”) dated as of December 21, 1987 which was recorded in the Office of the City Register, New York County (the “Register’s Office”) in Reel 1344 at page 2162; (ii) CHC does not own the Building or the Land but leases same from The City of New York (the “City”) pursuant to a lease (the “City Lease”) dated June 30, 1960 which was recorded in the Register’s Office in Reel 864 at page 247 and which was restated in its entirety by instrument dated December 21, 1987 recorded in the Register’s Office in Reel 1344 at page 2051; (iii) the Building Lease, among other things, is subject to, among other things, a Restrictive Declaration (the “Restrictive Declaration”) dated as of July 20, 1987 which was recorded in the Register’s Office in Reel 1317 at page 1170; and (iv) the Building Lease has been mortgaged to UBS Real Estate Securities Inc. (“UBS”) pursuant to a Consolidated, Amended and Restated Mortgage and Security Agreement, dated as of September 25, 2007, which was recorded in the Register’s Office (the “Mortgage”). Tenant hereby further acknowledges and agrees that each of the Building Lease, the City Lease, the Restrictive Declaration and the Mortgage may at any time and from time to time be amended, modified, supplemented, restated and/or replaced and that the Building Lease, the City Lease, the Restrictive Declaration and the Mortgage and all such amendments, modifications, supplementations, restatements and replacements shall, in all respects, be superior and prior to this lease, it being expressly recognized by Tenant that the Building Lease, the City Lease and the Mortgage constitute “ground or underlying leases” and a “mortgage”, respectively, as those terms are used in this Article and Article 7 hereof and that this lease is in all respects subject and subordinate thereto and to the Restrictive Declaration. In confirmation of such subordination, Tenant shall execute, acknowledge and deliver to Owner within ten (10) days after demand any certificate that Owner may request.

(b) If by reason of a default on the part of Owner, as lessee under the Building Lease or any other ground or underlying lease, in the performance of any of the terms or provisions of such lease or for any other reason whatsoever, such lease and the leasehold estate of Owner as lessee thereunder is terminated by summary proceeding or otherwise, or if such lease and such leasehold estate is acquired through foreclosure proceedings brought by the holder of the Mortgage or any other mortgage to which such lease is or may become subject or subordinate, or in case of any termination or acquisition of any other lease covering the Building or any foreclosure of any mortgage affecting the real property of which the demised premises is a part, or if for any other reason any party holding any interest in the Building (or any designee of such party) shall succeed to Owner’s rights, Tenant shall attorn to the lessor under such lease, the purchaser in such foreclosure proceedings or such other party, as the case may be, and shall recognize such lessor, purchaser or other party as Tenant’s landlord under this lease, unless the lessor under such lease or the holder of any such mortgage in any such proceedings shall elect in connection therewith to terminate this lease and the rights of Tenant to the possession of the demised premises. Tenant shall execute and deliver at any time and from time to time, upon the request of Owner, the lessor under any such ground or underlying lease, or such

mortgagee or purchaser, any instrument which may be necessary or appropriate to evidence such attornment (including, without limitation, a direct lease) and Tenant hereby irrevocably constitutes and appoints Owner as Tenant’s attorney-in-fact, to execute and deliver any such instrument for and on behalf of Tenant. Such attornment by Tenant shall contain, among other things, provisions to the effect that in no event shall such lessor, mortgagee or purchaser, as landlord: (i) be obligated to repair, replace or restore the Building or the demised premises in the event of damage or destruction, beyond such repair, replacement or restoration as can be reasonably accomplished from the net proceeds of insurance actually received by or made available to such landlord; (ii) be responsible for any previous act or omission of the landlord or the tenant under such ground or underlying lease or for the return of any security deposit unless actually received by such landlord; (iii) be subject to any liability or offset accruing to Tenant against Owner; (iv) be bound by any previous modification or extension of this lease or any cancellation or surrender of same unless previously approved in writing; (v) be bound by any previous prepayment of more than one month’s rent or other charge; (vi) be bound by any obligation to make any payment to Tenant which was required to be made prior to the time such lessor, mortgagee or purchaser succeeded to Owner’s interest hereunder; or (vii) be bound by any obligation under this lease to perform any work or make any improvements to the demised premises to prepare same for Tenant’s occupancy. Tenant further waives the provisions of any statute or rule of law now or hereafter in effect which may give or purport to give Tenant any right of election to terminate this lease or to surrender possession of the demised premises in the event such ground or underlying lease terminates or any such summary proceeding or foreclosure proceeding is brought by the lessor under any such ground or underlying lease or the holder of any such mortgage, and agrees that, unless and until any such lessor under any such ground or underlying lease or holder of any such mortgage in connection with any such proceeding shall elect to terminate this lease and to extinguish the leasehold estate of Tenant hereunder, this lease shall not be affected in any way whatsoever by any such proceeding or termination.

(c) If any act or omission of Owner would give Tenant the right, immediately or after lapse of a period of time, to cancel or terminate this lease, or to abate or offset against the payment of rent or to claim a partial or total eviction (whether actual or constructive), Tenant shall not exercise such right: (i) until it has given written notice of such act or omission to Owner at the address first set forth above, CHC at 881 Seventh Avenue, New York, New York 10019, the City at Municipal Building, 17th floor, New York, New York 10048, UBS at 1285 Avenue of the Americas, New York, New York 10019, Attn: Jeffrey Lavine with a copy to: Cadwalader, Wickersham & Taft LLP, One World Financial Center, New York, New York 10281, Attn: William P. McInerney, and every other superior mortgagee and superior lessor whose name and address shall have been furnished to Tenant; and (ii) until a reasonable period for remedying such act or omission shall have elapsed following the giving of such notice and following the time when each such superior mortgagee or superior lessor shall have become entitled to remedy the same (which reasonable period shall in no event be less than the period to which Owner would be entitled under this lease or otherwise, after similar notice, to effect such remedy plus thirty (30) business days).

(d) Except for any deposits that may be required hereunder and amounts to be paid on account of expenses incurred or to be incurred by Owner, Tenant shall not pay rent for more than one (1) month in advance and shall, promptly following request of CHC (made not more often than once annually), deliver to CHC a statement of the rent paid by Tenant to Owner during the prior year.

41. Intentionally Omitted.

42. Preparation of the Demised Premises:

(a) Tenant shall accept the demised premises in their then existing condition, “as is” and Owner shall have no obligation to perform any work or installations, supply any materials or equipment and/or incur any cost or expense in preparation of the demised premises for Tenant’s occupancy. The taking of possession of the demised premises by Tenant shall be conclusive evidence as against Tenant that at the time such possession was taken, the demised premises and the Building were in good and satisfactory condition.

(b) Tenant shall be permitted eight (8) hours total of freight elevator use in connection with Tenant’s move-in to the demised premises at no charge to Tenant, subject to scheduling in accordance with Owner’s standard procedures.

43. Limitation on Liability:

(a) Tenant shall look only to Owner’s estate and interest in the Building for the satisfaction of Tenant’s remedies or for the collection of a judgment (or other judicial process) requiring the payment of money by Owner in the event of any default or liability by Owner hereunder or otherwise, and no other property or assets of Owner and no property of any officer, employee, director, shareholder, member, partner or principal of Owner (disclosed or undisclosed) shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this lease, the relationship of Owner and Tenant hereunder, Tenant’s use or occupancy of the demised premises or otherwise.

(b) Neither any: (i) performance by Owner, Tenant or others, of any repairs, improvements, alterations, additions, installations, substitutions, betterments or decorations in or to the Building (or any portion thereof) or the demised premises; (i) failure of Owner or others to make any repairs or improvements; (iii) damage to the Building (or any portion or element thereof), the demised premises or Tenant’s property; (iv) injury to any persons, caused by other tenants or persons in the Building, or by operations in the construction of any private, public or quasi-public work, or by any other cause; (v) latent defect in the Building (or any portion or element thereof) or the demised premises; (vi) temporary covering, darkening, closure or bricking up of any windows of or any particular entrances to the demised premises (provided Tenant is not deprived of all access to the demised premises) for any reason whatsoever including, without limitation, Owner’s own acts, nor any permanent covering, permanent darkening, permanent closure or permanent bricking up of any such windows or entrances if required by law, any insurance requirement or in connection with any alteration to the Building and/or the development of other property by Owner or others and/or construction upon any property near or adjacent to the Building and/or the Land (or any part thereof) by Owner or others; nor (vii) inconvenience or annoyance to Tenant or injury to or interruption of Tenant’s business by reason of any of the events or occurrences referred to in the foregoing subdivisions (i) through (vi) shall impose any liability on Owner to Tenant or any other party (other than as may be imposed by law upon Owner for its negligence or the negligence of its agents in the operation or maintenance of the Building (or any portion or element thereof) or for the breach by Owner of any express covenant of this lease on Owner’s part to be performed) or entitle Tenant to any

compensation therefor or abatement of rent nor shall the same release Tenant from any obligation under this lease nor constitute an eviction. No representation, guaranty or warranty is made that the Building communications or security systems, devices or procedures of the Building will be effective to prevent injury to Tenant or any other person or damage to, or loss (by theft or otherwise) of, any of Tenant’s property or of the property of any other person, and Owner reserves the right to discontinue or modify at any time any Building communications or security systems or procedures without liability to Tenant.

(c) Neither Owner, any lessor of a superior lease or holder of a superior mortgage, Owner’s agents, nor any of their respective officers, directors, shareholders, partners or principals (disclosed or undisclosed) (collectively, the “Indemnitees”) shall be liable to Tenant or Tenant’s agents, employees, contractors, invitees, subtenants or licensees or any other occupant of the demised premises, in connection with or arising from any injury to Tenant or to any other person or for any damage to, or loss (by theft or otherwise), of any of Tenant’s personal property or of the property of any other person, irrespective of the cause of such injury, damage or loss (including the acts or negligence of any tenant or of any owners or occupants of adjacent or neighboring property or caused by operators in the construction of any private, public or quasi-public work), unless solely due to the gross negligence of Owner or Owner’s agents, it being understood that no property, other than such as might normally be brought upon or kept in the demised premises as incidental to the reasonable use of the demised premises for the purposes herein permitted will be brought upon or be kept in the demised premises; provided, however, that even if due to any such gross negligence of Owner or Owner’s agents, in no event shall any of the Indemnitees ever be liable with respect to any claim for consequential damages in connection therewith. Any Building employee to whom any property shall be entrusted by or on behalf of Tenant shall be deemed to be acting as Tenant’s agent with respect to such property and neither Owner nor Owner’s agents shall be liable for any loss of or damage to any such property by theft or otherwise.

44. Insurance and Indemnity:

(a) In furtherance of the obligations of Tenant set forth in this Article and elsewhere in this lease (but not in limitation thereof) and as an independent and material covenant forming a part hereof, Tenant shall, at its sole cost and expense, carry and maintain in force throughout the Term: (i) worker’s compensation and other required statutory forms of insurance, in statutory limits; (ii) comprehensive general public liability insurance, which shall be written on an occurrence basis (and shall include, without limitation, a contractual liability endorsement and personal injury coverage), naming Tenant as the insured and naming Owner (as that term was broadly defined for purposes of this Article only) and Owner’s current managing agent, TF Cornerstone Inc., and any future managing agent, as additional insureds, in limits (subject to increase at Owner’s reasonable request) of not less than $3,000,000 combined single limit for bodily and personal injury or death and for property damage per occurrence, including water damage and sprinkler leakage legal liability, protecting Owner from all such claims for bodily or personal injury or death or property damage occurring in or about the demised premises and its appurtenances; and (iii) “all risk” property insurance covering all furniture, furnishings and equipment now or hereafter located in, on or about the demised premises and all improvements and betterments (whether permanent or temporary) made in, to or on the demised premises by, for or at the request of Tenant and regardless of the ownership thereof to a limit of not less than the full replacement cost thereof. The limits of insurance specified herein shall not limit

Tenant’s liability. All insurance required to be maintained by Tenant shall be carried with a company or companies rated “A+10” or better by Best Insurance Guide and licensed to do business in the State of New York and shall be written for terms of not less than one (1) year. Tenant hereby agrees to furnish Owner with certificates evidencing the maintenance of such insurance and the payment of the premiums therefor prior to the Commencement Date, and with renewals thereof and evidence of the payment of the premiums therefor at least thirty (30) days prior to the expiration of any such policy or policies. Such policy or policies shall also provide that it or they shall not be cancelled or altered without giving Owner at least thirty (30) days’ prior written notice thereof, sent to Owner by certified mail at Owner’s address to which notices are required to be sent to Owner hereunder. Upon Tenant’s default in obtaining or delivering any such policy or policies or failure to pay the premiums therefor, Owner (in addition to and not in limitation of its other rights, remedies and privileges by reason thereof) may (but shall not be obligated to) secure or pay the premium for any such policy or policies and charge Tenant as additional rent therefor an amount equal to 110% of Owner’s costs therefor. Tenant hereby agrees to cooperate with Owner in connection with the collection of any insurance proceeds that may be due in the event of a loss and agrees to execute and deliver to Owner such proofs of loss and other instruments as may be required to recover such insurance proceeds.

(b) (i) Owner shall, if obtainable at no additional cost, include in its fire insurance policies appropriate clauses pursuant to which the insurance companies: (x) waive all right of subrogation against Tenant with respect to losses payable under such policies; and/or (y) agree that such policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policies. But should any additional premiums be exacted for any such clause or clauses, Owner shall be released from the obligation hereby imposed unless Tenant shall agree to pay such additional premium.

(ii) Tenant shall include, if obtainable at no additional cost, in its fire insurance policy or policies on its furniture, furnishings, fixtures and other property removable by Tenant under the provisions of this lease appropriate clauses pursuant to which the insurance company or companies: (x) waive the right of subrogation against Owner and/or any tenant of space in the Building with respect to losses payable under such policy or policies; and/or (y) agree that such policy or policies shall not be invalidated should the insured waive in writing prior to a loss any or all right of recovery against any party for losses covered by such policy or policies. But should any additional premium be exacted for any such clause or clauses, Tenant shall be released from the obligation hereby imposed unless Owner or the other tenants shall agree to pay such additional premium. Tenant hereby acknowledges and agrees that in no event and under no circumstances shall Owner have any responsibility to insure Tenant’s improvements, fixtures, furniture, furnishings or other personalty and that Tenant shall be solely responsible therefor.

(iii) Provided that Owner’s right of full recovery under its policy or policies aforesaid is not adversely affected or prejudiced thereby, Owner hereby waives any and all right of recovery which it might otherwise have against Tenant, its servants, agents and employees, for loss or damage occurring to the Building and the fixtures, appurtenances and equipment therein, to the extent the same is covered by Owner’s insurance, notwithstanding that such loss or damage may result from the negligence or fault of Tenant, its servants, agents or employees. Provided that Tenant’s right of full recovery under its aforesaid policy or policies is not adversely affected or prejudiced thereby, Tenant hereby waives any and all right of recovery which it might otherwise have against Owner, its

servants, and employees, and against every other tenant in the Building who shall have executed a waiver similar to the one herein set forth for loss or damage to, Tenant’s furniture, furnishings, fixtures and other property, notwithstanding that such loss or damage may result from the negligence or fault of Owner, its servants, agents or employees, or such other tenant and/or the servants, agents or employees thereof.

(iv) Owner and Tenant shall advise the other promptly if the clauses to be included in their respective insurance policies pursuant to subdivisions (i) and (ii) hereof cannot be obtained. Owner and Tenant shall notify the other promptly of any cancellation or change of the terms of any such policy which would affect such clauses.

(c) Tenant hereby releases Owner (which term as used throughout this Article only shall include Owner’s employees, agents, partners, officers, shareholders and directors as well as all holders of any interest in the Building) from all liability, whether for negligence or otherwise, in connection with loss covered by any insurance policies which Tenant carries with respect to the demised premises, or any interest or property therein or thereon (whether or not such insurance is required to be carried under this lease), but only to the extent that such loss is collectible under such insurance policies.

(d) Tenant hereby assumes the sole responsibility for the condition, operation, management and control of the demised premises, and hereby covenants and agrees to indemnify and hold Owner harmless from and against all claims, actions, judgments, damages, liabilities or expenses including, without limitation, reasonable attorneys’ fees, in connection with damage to property or injury or death to persons, arising from or out of the use, alteration, occupation, management, possession or control of the demised premises, or occasioned wholly or in part by any act or omission of Tenant, its agents, employees, contractors, subtenants, invitees, licensees and the like, or any breach by Tenant of its obligations under this lease. In case Owner (as that term was broadly defined for purposes of this Article only) shall ever be made a party to any litigation commenced against Tenant, Tenant shall protect and hold Owner harmless and shall pay all costs and expenses including, without limitation, reasonable attorneys’ fees, incurred or paid by Owner in connection with such litigation. Upon request by Owner, Tenant shall resist and defend any such action or proceeding by counsel chosen by Tenant who shall be reasonably satisfactory to Owner. Tenant or its counsel shall keep Owner fully apprised at all times of the status of such defense.

45. Change of Condition:

Owner shall not be liable for any change of condition in the demised premises caused by the compliance with any present or future laws, rules, orders, ordinances, requirements, or regulations of any Federal, State, County or Municipal authority or government, including any change required by law for off-street parking or similar legislation, or by revocation by any such authority or authorities of any permit or license heretofore granted, or by construction or operation of any public or quasi-public work, or by the erection of any building or buildings upon any adjacent property, or by change of environment. Owner shall not be liable for interference with or loss of light, views, air or other incorporeal hereditaments.

46. Brokerage:

Tenant represents, warrants and confirms to and for the benefit of Owner that Tenant has not dealt with any broker or agent other than the Broker as identified in the Basic Lease Provisions with respect to this lease and the demised premises. As a special inducement for the execution and delivery of this lease by Owner (without which Owner would not have executed and delivered same), Tenant hereby agrees to indemnify and save Owner harmless of, from and against any and all claims (and all expenses and fees including, without limitation, attorneys’ fees related thereto) for commissions, fees or other compensation made by any other broker or entity claiming to have brought the availability of the demised premises to Tenant or otherwise arising out of or relating to the acts of Tenant, its employees, officers, shareholders, partners and/or agents. In case any action or proceeding shall be instituted against Owner for the payment of any such commissions, fees or other compensation, Tenant, upon notice from Owner and at Tenant’s sole cost and expense, shall resist and defend such action or proceeding by counsel chosen by and paid for by Tenant, who shall be reasonably satisfactory to Owner, and Owner shall also have the right, but not the obligation, to participate in the defense of any such action or proceeding by counsel of its own choice. The provisions of this Article shall survive the Expiration Date.

47. Estoppel:

Tenant shall, at any time and from time to time, as requested by Owner, upon not less than ten (10) days’ prior notice, to execute, acknowledge and deliver to Owner and/or to any other person, firm, or entity specified by Owner, a statement certifying that this lease is unmodified and in full force and effect (or if there have been modifications that the same is in full force as modified and stating the modifications), certifying the dates to which Base Rent and additional rent have been paid, and stating whether or not, Owner is in default in the performance of any of its obligations under this lease, and, if so, specifying each such default, it being intended that any such statement delivered pursuant hereto may be relied upon by Owner and any other parties with whom Owner may be dealing.

48. Late Payment Charge; Accord and Satisfaction; Application of Payments; End of Term:

(a) If Tenant shall make any payment of Base Rent, additional rent or other charges more than ten (10) days after the same shall be first due or payable, Tenant shall pay Owner: (i) as and for agreed upon late charges (and not a penalty) on account of Owner’s additional administrative, accounting and overhead costs attributable to Tenant’s delinquency, ten cents for each dollar that is not timely paid and (ii) an amount equal to the lesser of: (a) 18% per annum; or (b) the highest rate permitted by law, calculated on the amount not paid when due, from the due date until the date of payment. All amounts payable to Owner pursuant to this Article shall be considered additional rent. Nothing contained in this Article or otherwise is intended to grant Tenant any extension of time in respect of the due dates for any payments under this lease, nor shall same be construed to be in limitation of or in substitution for any other rights, remedies or privileges available to Owner under this lease, at law, in equity or otherwise.

(b) No payment by Tenant or receipt or acceptance by Owner of a lesser amount than the correct amount of Base Rent or additional rent shall be deemed to be other than a payment on account, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, and if Owner, in its discretion, accepts such check or payment, such acceptance shall be without prejudice to Owner’s right to recover the balance or pursue any other remedy available to Owner under this lease, at law or in equity. The collection by Owner of Base Rent or additional rent with knowledge of a default by Tenant shall not be deemed a waiver of such default or of any of the rights or remedies available to Owner hereunder or otherwise.

(c) If Tenant is in arrears in the payment of Base Rent or additional rent, Tenant waives Tenant’s right, if any, to designate the items to which any payments made by Tenant are to be credited, and Owner may, in its discretion, apply any payments made by Tenant to such items as Owner sees fit, irrespective of and notwithstanding any designation or request by Tenant as to the items which any such payments shall be credited.

(d) All checks tendered to Owner from anyone other than Tenant as and for the Base Rent and/or additional rent reserved hereunder may, at Owner’s discretion, be deemed payments for the account of Tenant. Acceptance by Owner, in its discretion, of Base Rent and/or additional rent from anyone other than Tenant shall not be deemed to operate as (1) an attornment to Owner by the payor of such rent and/or additional rent, (2) the consent of Owner to an assignment of this lease or subletting by Tenant of the demised premises to such payor, (3) an acknowledgement or agreement by Owner that such payor has any right to possess or otherwise use or occupy the demised premises, (4) a modification of any of the provisions of this lease or (5) a waiver of Owner’s right to refuse to accept future payments from anyone other than Tenant.

(e) Article 22 hereof is hereby amended to add the following: “If the demised premises are not surrendered and vacated as and at the time required by this lease (time being of the essence), Tenant shall be liable to Owner for: (i) all losses and damages which Owner may incur or sustain by reason thereof, including, without limitation, reasonable attorneys’ fees, and Tenant shall indemnify and hold harmless Owner against all claims made by any succeeding tenants against Owner or otherwise arising out of or resulting from the failure of Tenant timely to surrender and vacate the demised premises in accordance with the provisions of this lease; and (ii) per diem use and occupancy in respect of the demised premises equal to two and one-half (2 1/2) times the Base Rent and additional rent payable hereunder for the last year of the Term (which amount Owner and Tenant presently agree is contemplated by them as being fair and reasonable under the circumstances and not a penalty). In no event shall any provision hereof be construed as permitting Tenant to hold over in possession of the demised premises after expiration or termination of the Term.”

(f) Article 3 hereof is hereby amended to add the following thereof: “In addition to Tenant’s removal and restoration obligations set forth in this Article 3, unless Owner shall agree to the contrary in writing following Tenant’s specific request as to whether Tenant shall be required to remove the proposed alteration, installation or other work made to Owner simultaneously with Tenant’s request for Owner’s approval of the proposed alteration, installation or other work, Tenant shall be required to remove, no later than thirty (30) days prior to the Expiration Date or earlier termination of the Term, any vaults and raised floors, kitchens, kitchen appliances and pantries, staircases, antennas or any other “specialty” installations or alterations which, in Owner’s determination, are either not consistent with standard general and administrative office use or are likely to materially increase the cost of demolishing or reletting the demised premises. If removal is so required, such removal shall be performed, at Owner’s option, by Owner at Tenant’s sole cost and expense or by Tenant at its sole cost and expense, including without limitation the cost to repair and restore in a good and workerlike manner any damage to the demised premises or the Building caused by such removal, to the condition same were in as of the Commencement Date (reasonable wear and tear excepted). The provisions of this Article 3 shall survive the expiration or termination of this lease.”

49. Arbitration:

(a) Either party may request arbitration of any matter in dispute wherein arbitration is expressly provided in this lease as the appropriate remedy. The arbitration shall be conducted, to the extent consistent with this Article, in accordance with the then applicable rules of the American Arbitration Association (or any organization successor thereto) in the City and County of New York. The arbitrator(s) shall: (i) be disinterested person(s) having at least ten (10) years of experience in the County of New York in a calling connected with the dispute; and (ii) have the right to retain and consult experts and competent authorities skilled in the matters under arbitration. In rendering any decision or award hereunder, the arbitrator(s) shall not add to, subtract from or otherwise modify the provisions of this lease.

(b) The fees and expenses of the arbitrator(s) and all other expenses (not including the attorneys’ fees, witness fees and similar expenses of the parties) of the arbitration shall be borne by the parties equally.

50. Addendum to Article 3:

(a) Supplementing Article 3 hereof, Tenant agrees that with respect to the performance by Tenant of any alterations, additions, improvements or installations to the demised premises costing in excess of $10,000 Tenant shall pay to Owner, as additional rent hereunder, promptly upon being billed therefor, a sum equal to ten (10%) percent of the cost of such alterations, additions, improvements or installations for Owner’s indirect costs, field supervision and coordination in connection therewith.

(b) If Tenant repairs or removes any mechanical or other equipment within the demised premises containing chlorofluorocarbons (“CFC’s”), the repair or removal of such equipment, as the case may be, shall conform with all requirements of law and industry practices. Additionally, any such repair or removal shall be done by contractors approved by Owner and subject to the procedures to which Owner’s consent shall have previously been obtained. Tenant shall indemnify and hold Owner harmless from any liability or damages resulting from any contamination within the Building as a result of the repair or removal by Tenant of any of the aforesaid equipment containing CFC’s.

51. Addendum to Article 6:

For the purposes of this Lease, the term “Legal Requirements” shall mean all laws (including, without limitation, the Landmarks Law (as hereinafter defined)), statutes and ordinances (including, without limitation, Building codes and zoning regulations and ordinances) and the orders, rules, regulations, directives and requirements of all federal, state, county, city and borough departments, bureaus, boards, agencies, offices, commissions and other subdivisions thereof, or of any official thereof, or of any other governmental public or quasi-public authority, whether now or hereafter in force, which may be applicable to the Land, the interior and/or the exterior of the Building or the demised premises or any part thereof, or the sidewalks, curbs or areas adjacent thereto and all requirements, obligations and conditions of all instruments of record on the date of this lease.

52. Addendum to Article 11:

Article 11 hereof is hereby amended to add the following:

(a) (1) If Tenant desires to assign this lease or sublet the demised premises, Tenant shall promptly notify Owner thereof in writing. Upon obtaining a proposed assignee or subtenant upon terms satisfactory to Tenant, Tenant shall submit to Owner in writing a request for Owner’s consent, together with: (i) the name of the proposed assignee or subtenant; (ii) the terms and conditions of the proposed assignment or subletting; (iii) the nature and character of the business which the proposed assignee or subtenant proposes to conduct in the demised premises; (iv) current financial statements and banking and other references of such proposed assignee or subtenant; and (v) such other information concerning such proposed assignment or subletting as Owner may reasonably request.

(2) Within thirty (30) business days following Owner’s receipt of the request and other items specified in the last sentence of subparagraph (1) of this Paragraph (a), Owner may notify Tenant that Owner elects to: (a) cancel this lease, in which event such cancellation shall become effective on the date proposed by Tenant for such assignment or subletting and this lease shall thereupon terminate on said date with the same force and effect as if said date were the expiration date of this lease; or (b) require Tenant to assign this lease to Owner (or Owner’s designee) effective on the date proposed by Tenant for such assignment or subletting. (From and after the effective date of an assignment of this lease required to be made by Tenant to Owner (or Owner’s designee) pursuant to this subparagraph (2), Tenant shall be relieved of all of its obligations hereunder in respect of time periods occurring after the effective date of such assignment except for those obligations which are herein made to survive the expiration of this lease.) In the event that Landlord exercises its recapture rights and cancels the Lease, Tenant’s obligations under the Lease, including all financial obligations (except those that survive termination of the Lease), shall terminate on the effective date of cancellation of the Lease. Notwithstanding anything to the contrary above in this Section 52(a)(2), in the event that Owner elects either (a) or (b) above, Tenant shall have the right to rescind the Tenant request to assign the Lease or sublease the Premises which gave rise to such exercise by Owner provided such notice of revocation is delivered to Owner within five (5) days following Owner’s delivery of notice of election to either cancel or take an assignment of this Lease as above provided; whereupon this Lease shall continue in full force and effect as though the request for assignment or sublet had never been made by Tenant.

(a) In the event that Owner shall not exercise either of its options under Paragraph (a) of this Article then provided that Tenant has not defaulted hereunder, Owner shall not unreasonably withhold or delay its consent to the proposed assignment or subletting. In no event and under no circumstances, however, shall Owner be required to consent to, and Tenant shall not propose, a subletting of less than all of the demised premises or an assignment or subletting: (i) to any person, firm or entity (or subdivision, affiliate or subsidiary of any firm or entity) that shall, at the time of such proposal, or within six (6) months prior thereto, be or have been a tenant, subtenant or occupant of space in the Building or be or have been negotiating with Owner or its agent to become a tenant, subtenant or occupant of space therein; (ii) to any person or entity that shall: (a) be a government or

governmental agency, department or affiliate thereof; (b) in any way be dependent upon government or donation financing for support; or (c) be prohibited from becoming a tenant or occupant of space in the Building by any document, instrument or covenant encumbering the Building that is superior to this lease or by the holder or beneficiary of same; or (iii) if the demised premises are to be used in violation of Article 2 hereof or for an auction room, bank, trust company, savings and loan company; stock brokerage firm, school, medical facility or office, public stenographic service, political campaign office, or governmental (foreign or domestic) agency, department or office, labor union offices or hiring hall, dance or music, modeling or art studio, radio or television broadcasting transmission activities, sound recording studio, talent or audition agency, travel agency, personnel or employment agency, gymnasium, restaurant or real estate brokerage business. Tenant shall not advertise or list the demised premises at a rental rate that is lower than the rental rate then being asked by Owner for comparable space in the Building. In the event that Tenant advertises or lists the demised premises at a rental rate lower than the rental rate then being asked by Owner for comparable space in the Building, Owner shall not be required to consent to any proposed subletting subsequent thereto. No pro tanto assignments of this lease shall be permitted under any circumstances whatsoever.

(b) As conditions precedent to granting consent to any proposed assignment or subletting, Owner may require that: (i) in the case of a proposed sublease, Tenant first agree, in a written agreement satisfactory to Owner (which agreement shall be secured by a collateral assignment of any such sublease, and/or such other security as Owner may require) to pay monthly to Owner, as additional rent hereunder, fifty percent (50%) of all rent and/or other consideration payable by the proposed subtenant to Tenant to the extent that such rent and/or other consideration exceeds, on a pro rata basis, the sum, amount or rate of the Base Rent at the time payable hereunder by Tenant; (ii) in the case of a proposed assignment, Tenant pay to Owner, as additional rent hereunder, fifty percent (50%) of any and all consideration payable by the proposed assignee to Tenant; (iii) Tenant and its proposed assignee or subtenant provide Owner with such other information as it may reasonably request, including (but not limited to) a certification in affidavit form of all rental and other consideration proposed to be paid in connection with the proposed assignment or subletting; and (iv) the proposed assignment or sublease and the documentation evidencing and/or executed or delivered in connection with same shall be otherwise reasonably acceptable to Owner; provided, if (i) and (ii) above occur in connection with the sale (either through an asset or stock transaction) of the business of Tenant, the “consideration payable” is not intended to include the consideration paid to Tenant for the business.

(c) If Owner shall grant its consent to a proposed assignment of this lease or subletting of the demised premises or any part thereof, such consent and the effectiveness of any such assignment or subletting shall nevertheless be conditioned upon Tenant delivering to Owner at least ten (10) business days prior to the effective date thereof: (i) an executed duplicate original of the sublease or assignment in the form previously approved by Owner which, among other things, contains the provisions required by: (a) Paragraph (c) of Article 61 of this lease; and (b) Paragraph (p) of Article 62 of this lease; and (ii) in the event of an assignment, an assumption agreement wherein the assignee (except Owner or its designee) agrees to assume directly for the benefit of Owner all of the terms, covenants and conditions of this lease to be performed by Tenant and which provides that the tenant named herein and such assignee shall be jointly and severally liable for the performance of all of the terms, covenants and conditions of this lease. Every assignment of this lease or subletting hereunder shall be expressly subject to the condition and restriction that this lease or sublease shall not be further

assigned, encumbered or otherwise transferred or the subleased premises further sublet by the subtenant in whole or in part, or any part of the demised premises used or occupied by others, without Owner’s prior written consent. Every subletting hereunder shall be subject to the express condition, and by accepting a sublease hereunder each subtenant shall be conclusively deemed to have agreed, that such sublease is subject and subordinate to this lease in all respects and that if this lease should be terminated prior to the expiration date herein set forth or if Owner shall succeed to Tenant’s estate in the demised premises, then at Owner’s election the subtenant shall attorn to and recognize Owner as the subtenant’s landlord under the sublease, any provision of law to the contrary notwithstanding; and the subtenant shall promptly execute and deliver to Owner any instrument Owner may reasonably request to evidence such attornment, and each subtenant shall conclusively be deemed to have appointed Owner its attorney-in-fact to execute and deliver any such certificate for and on behalf of such subtenant.

(d) Tenant covenants that notwithstanding any subletting of the demised premises, any assignment of this lease or any assumption of this lease by an assignee, Owner’s consent to any assignment or subletting and/or Owner’s acceptance of rent or additional rent from any subtenant or assignee, Tenant and each immediate and remote successor in interest to Tenant shall and will remain fully liable, jointly and severally (as a primary obligor) for the payment of the Base Rent and additional rent due and to become due hereunder and for the performance of all the covenants, agreements, terms, provisions and conditions contained in this lease on the part of Tenant to be performed.

(e) Subject to paragraph (h) below, if Tenant is a corporation, any sale, assignment, transfer, pledge, encumbrance or other disposition of any of the stock of Tenant, or if Tenant is a partnership or a limited liability company, any sale, assignment, transfer, pledge, encumbrance or other disposition of any interest in such partnership or limited liability company shall, for the purposes hereof, be considered an assignment and shall be subject to the provisions of this Article.

(f) Tenant hereby agrees not to advertise or in any manner to list the demised premises, or any part thereof, for rent or assignment or subletting without Owner’s prior written consent in each instance, which consent shall not be unreasonably withheld in the case of a proposed advertisement which does not use the words “Carnegie Hall” and which does not specify the name of the Building or identify Owner, any of its agents or partners or any other party in the chain of title. Any consent granted by Owner pursuant to this Paragraph (g) shall not, in any event, alter or modify the other provisions of this lease related to assignments or sublettings by Tenant.

(g) Notwithstanding anything to the contrary set forth in this Lease, including, without limitation, the provisions of Paragraph (f) of this Article and provided Tenant is not in default beyond the expiration of any applicable notice and cure periods, Tenant may, without Owner’s consent and on not less than ten (10) days prior written notice to Owner, which notice shall include an executed copy of either an assignment of this lease (which assignment shall provide that the assignee assumes directly for the benefit of Owner all of Tenant’s obligations under this lease, or in connection with a merger or consolidation by operation of law or by effective provisions contained in the instrument of merger or consolidation, meets the requirements of subclause (c)(ii) hereinbelow), or the sublease (which provides that said sublease is subject and subordinate to this lease in all respects), as the case may be, assign this lease or sublet the demised premises to, or otherwise permit the use of the demised premises by, an entity into which Tenant is merged or consolidated or to an entity which shall be an

“affiliate”, “subsidiary” or “successor” (each as hereinafter defined) of Tenant and the provisions of Paragraphs (a), (b) and (c) of this Article shall be inapplicable to such transaction. For purposes of this Paragraph: (a) an “Affiliate” of Tenant shall mean any entity which controls, is controlled by or is under common control with Tenant (“Control” being interpreted as the ownership of more than fifty (50%) percent of the stock or the interests in such entity, as applicable, and possession of the power to direct stock or the interests in such entity, as applicable, and possession of the power to direct the management and policies of such entity and the distribution of its profits); (b) a “Subsidiary” of Tenant shall mean an entity not less than fifty-one (51%) percent of which is owned and controlled by Tenant; and (c) a “Successor” of Tenant shall mean an entity (i) which acquires all or substantially all of the property and assets of Tenant, in a bona fide transaction and the transaction is not being done to circumvent the prohibitions and provisions of this Article and Article 11 of this Lease) and assumes all or substantially all of the obligations and liabilities of Tenant (including, without limitation, this lease) or (ii) into which or with which Tenant is merged or consolidated, which entity is subject to the jurisdiction of the court of the State of New York and which succeeds Tenant in accordance with applicable statutory provisions for merger or consolidation of entities, provided that, by operation of law or by effective provisions contained in the instruments of merger or consolidation, such entity fully assumes the liability of the entities participating in such merger or consolidation; provided further that, on the completion of every acquisition, merger, consolidation, assumption or other transaction in this subclause (c) described, the successor shall have a net worth at least equal to the greater of: (x) Tenant’s net worth on the date hereof; or (y) Tenant’s net worth immediately prior to the effective date of such acquisition, merger consolidation, assumption or other transaction, as applicable.

(h) Tenant shall have the right to permit one or more divisions, Affiliates or Subsidiaries of Tenant (each a “Permitted User”) to use space in the Demised Premises. Notwithstanding anything to the contrary in this Article 52, each Permitted User shall be allowed such use, without Owner’s consent, but upon at least ten (10) days’ prior notice to Owner upon the following conditions: (i) Owner or Owner’s agent shall not be litigating against such proposed Permitted User within the prior twelve (12) months, (ii) the Permitted User shall not be entitled, directly or indirectly, to diplomatic or sovereign immunity and shall be subject to service of process in, and the jurisdiction of the court of, the State of New York, (iii) there will be no separate entrances and demising walls for the Permitted User, (iv) the total number of Permitted Users using desk space pursuant to this Paragraph (j) shall not exceed two (2) at any one time, (v) the aggregate number of rentable square feet used by all Permitted Users at any one time shall not exceed 25% of the then rentable square footage of the Demised Premises and (vi) Tenant shall receive no rent, payment or other consideration in connection with such occupancy in respect of such space other than rent payments (in no event greater per rentable square foot than the Base Rent and any recurring Additional Rent, payable hereunder per rentable square foot ) or other consideration for actual services rendered or provided by or for such occupant. With respect to each and every Permitted User, the following shall apply: (i) each Permitted User shall have no privity of contract with Owner and therefore shall have no rights under this Lease, and Owner shall have no liability or obligation to the Permitted User under this Lease for any reason whatsoever in connection with such use or occupancy, which use and occupancy shall be subject and subordinate to this Lease, (ii) each Permitted User shall use the Premises in conformity with all applicable provisions of this Lease, and (iii) Tenant shall be liable for the acts of such Permitted User in the Leased Premises.

(j) Any assignment or subletting made in contravention of the provisions of this Article shall constitute a material breach of the covenants contained in this Article; and any such assignment or subletting shall not be binding upon Owner and, at Owner’s option, may be treated as a nullity and of no force or effect whatsoever against Owner.”

Except as specifically set forth in this Article, nothing in this Article is intended to modify the provisions of Article 11 of this lease.

53. Addendum to Article 29:

In the event Owner shall furnish cleaning service to the demised premises pursuant to the provisions of Article 29(d), Tenant covenants and agrees that Tenant shall pay to Owner on demand the costs incurred by Owner for: (a) extra cleaning work in the demised premises required because of: (i) misuse or neglect on the part of Tenant or its employees or visitors; (ii) use of portions of the demised premises for the preparation, serving or consumption of food or beverages, data processing or reproducing operations, private lavatories or toilets or other special purposes requiring greater or more difficult cleaning work than office areas; (iii) unusual quantity of interior glass surfaces; (iv) non-building standard materials or finishes installed by or at the request or Tenant; and (b) removal from the demised premises and the Building of so much of any refuse and rubbish of Tenant as shall exceed that ordinarily accumulated daily in the routine of business office occupancy.

54. Security:

Article 34 hereof is hereby amended to add the following:

(a) Notwithstanding the foregoing or anything to the contrary contained in this Article, at any time following Tenant’s deposit with Owner of the cash security to be deposited pursuant to this Article on or prior to the execution and delivery of this Lease and so long as no default exists beyond any applicable period of notice and cure, to secure the full and faithful performance by Tenant of all the terms, provisions, conditions, covenants and obligations (including, but not limited to, the payment of Base Rent and additional rent) on Tenant’s part to be performed hereunder, Tenant shall have the right to replace the cash deposited with Owner upon the execution of this Lease with the delivery to Owner of an unconditional, clean, irrevocable letter of credit, payable on sight, in the form of the letter of credit attached hereto as Exhibit C and made a part hereof (or such other form that is acceptable to Owner in its reasonable judgment), in an amount equal to the Security Deposit (as set forth in the Basic Lease Provisions), issued by and drawn upon a bank (the “Issuing Bank”) which shall be approved by Owner in writing (which approval shall not be unreasonably withheld, conditioned or delayed) and which shall be a member of the New York Clearing House Association licensed to do business in the State of New York by the New York State Banking Department (or federally chartered) and having banking offices located in Manhattan. Owner may present such letter of credit for payment upon the occurrence of any default by Tenant hereunder beyond the expiration of any applicable notice or grace period set forth herein and Owner may use, apply and/or retain the whole or any part of the proceeds of such letter of credit to the extent required for the payment of any rents or for any sum which Owner may expend or may be required to expend by reason of such default or for any other rents or sums due from Tenant but not timely received, including but not limited to any damages or deficiency in connection with the re-letting of the demised premises, whether accruing

before or after summary proceedings or other re-entry by Owner. Such letter of credit shall have an expiration date that is no earlier than sixty (60) days after the date fixed for the expiration of the Term. If notwithstanding the foregoing, such letter of credit shall for any reason whatsoever expire or have an earlier expiration date than required, then a subsequent or extension letter of credit (or, if acceptable in Owner’s reasonable judgment, an amendment to the letter of credit then if effect) in the amount of the then expiring letter of credit and otherwise acceptable to Owner in the exercise of its reasonable judgment shall be delivered by Tenant to Owner at least forty-five (45) days prior to the expiration date of the letter of credit it is replacing or amending (time being of the essence). If Tenant fails to timely deliver any subsequent or extension letter of credit or amendment to an existing letter of credit, as aforesaid, the letter of credit then in effect may be presented for payment and negotiated, notwithstanding that no other default may then exist under this lease. The proceeds of the letter of credit that is so negotiated shall be held by Owner in accordance with this Article.

(b) In the event that Tenant defaults under this lease in respect of any of the terms, provisions, conditions, covenants and obligations of this lease, including, but not limited to, the payment of Base Rent or additional rent, Owner may, without first applying any other security, use, apply or retain the whole or any part of the proceeds of the letter of credit delivered as the Security Deposit hereunder to the extent required for the payment of any rent or additional rent or any other sum as to which Tenant is in default or for any sum which Owner has incurred or may be required to incur by reason of Tenant’s default in respect of any of the terms, provisions, conditions, covenants and obligations on Tenant’s part to be performed hereunder, including, but not limited to, any damages or deficiencies in the re-letting of the demised premises which accrued before or after the commencement of summary proceedings or other re-entry by Owner. Tenant hereby acknowledges and agrees that the letter of credit delivered hereunder to Owner as the Security Deposit is intended to be for the sole benefit of Owner and not Tenant or any third party. Further, in the event of Tenant’s bankruptcy or insolvency, no portion of the Security Deposit is to be deemed to be the property or a part of the estate or assets of Tenant, as debtor, nor shall the same be subject to attachment, forfeiture or seizure by a trustee or other fiduciary on behalf of creditors of Tenant.

(c) Notwithstanding the foregoing or anything to the contrary set forth herein, Tenant acknowledges and agrees that, in the event Owner terminates this lease pursuant to Article 17 hereof following Tenant’s default in respect of any of the terms, provisions, conditions, covenants or obligations of this lease, Owner, at Owner’s sole option and in addition to any of its rights and remedies under Article 18 hereof, may elect to retain the entire proceeds of the letter of credit delivered as the Security Deposit hereunder or any cash deposited with Owner therefor under Article 34 hereof, in each case as liquidated damages, it being understood and agreed that Owner’s damages in the event of such termination of this lease would be difficult or impossible to ascertain and, under the circumstances, the amount of the Security Deposit is a fair and reasonable approximation of such damages and not a penalty.

(d) If the security is in the form of a letter of credit, in the event the Issuing Bank fails to promptly pay any partial sight draft on the letter of credit in accordance with its terms, Owner may, at its option and without notice to Tenant or other action on Owner’s part, draw down the entire letter of credit and thereafter hold the proceeds thereof in cash.

(e) If the security is in the form of a letter of credit, Tenant covenants that it will not assign or encumber, or attempt to assign or encumber the letter of credit, and that none of Owner, its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance.

(f) Every letter of credit deposited with Owner hereunder shall be transferable by its terms without charge to Owner or the transferee and shall name Owner and its successors, or any assignee of Owner, as the beneficiary thereunder. Upon any transfer of such security to an assignee of Owner, Owner shall be relieved of all further responsibility and liability with respect to such Security Deposit and Tenant agrees to look solely to such assignee of Owner for the return of the letter of credit or the proceeds thereof. The provisions of the preceding sentence are self-operative without the need for further documentation. Tenant shall not assign or encumber or attempt to assign or encumber the letter of credit or any of the proceeds thereof. In addition, each letter of credit deposited with Owner hereunder shall provide that Owner may, without the consent or involvement of Tenant, cause the issuer of the letter of credit to amend such letter of credit so as to name therein any successor to Owner (whether by merger, consolidation, reorganization, assignment or otherwise as permitted by applicable Legal Requirements) as the beneficiary thereof in lieu of the named owner herein or any successor-in-interest thereto. All costs relating to any such amendment to or transfer of said letter of credit shall be the responsibility of Tenant, and each letter of credit deposited with Owner hereunder shall provide that the payment of such costs shall be either deducted from Tenant’s account with the issuer of the letter of credit or billed directly to Tenant, without any involvement or action on the part of Owner.

(g) Supplementing Article 34 hereof, as long as major commercial banks having banking offices in the City and State of New York make interest-bearing security deposit accounts available, any cash security shall be placed by Owner or its agent in an interest-bearing account. Interest that may accrue thereon shall belong to Tenant, except such portion thereof as shall be equal to one (1%) percent per annum of said security or the total amount of the interest earned, whichever is less, which portion shall belong to and be the sole property of Owner as an administrative fee and Owner may withdraw said portion from time to time and retain same. That portion of the interest belonging to Tenant shall be accumulated and retained with such security and shall be considered part of said security; provided, however, following receipt of written request from Tenant for Tenant’s portion of the prior Lease Year’s earned interest, if any, no more often than annually beginning with the first anniversary of the Commencement Date, Owner shall, with commercially reasonable promptness, refund said Tenant’s portion of the interest to Tenant. The obligation to pay any taxes, whether income or otherwise, related to or affecting any interest earned on such cash security shall be the sole responsibility of Tenant and Tenant hereby agrees to timely pay same and to forever indemnify and save harmless Owner in respect thereof. Tenant shall, within ten (10) days after written demand therefor by Owner, furnish Owner with a tax identification number for use in respect of such cash security.”

55. Building Directory and Signs:

At the written request of Tenant, Owner shall list on the Building’s directory the name of Tenant, any other entity permitted to occupy any portion of the demised premises under the terms of this lease, and the executive officers, resident partners or employees of each of the foregoing entities provided the number of names so listed does not exceed five (5). The listing of any name other than

that of Tenant shall neither grant such party or entity any right or interest in this lease or in the demised premises nor constitute Owner’s consent to any assignment or sublease to, or occupancy of the demised premises by, such party or entity. In addition, Tenant shall have the right, at its cost and expense, to furnish and install a Building Standard sign identifying Tenant and any authorized subtenant on the entrance door of the demised premises provided that: (i) Owner shall first approve in writing the style, size, color, design and location of such sign and any changes to same; and (ii) Tenant shall, at its sole cost and expense, remove such sign from the entrance door to the demised premises on or before the expiration or any earlier termination of this lease and promptly repair and restore any damage to such door and/or the Building caused by such removal.

56. Certain Rights Reserved by Owner:

Owner hereby reserves and shall have the following rights, each of which Owner may exercise without liability to Tenant for damage or injury to property, person or business on account of the exercise thereof, and the exercise of any such rights shall not be deemed to constitute an eviction or disturbance of Tenant’s use or possession of the demised premises and shall not give rise to any claim for set-off or abatement of rent or any other claim:

(i) To install, affix and maintain any and all signs on the exterior and on the interior of the Building.

(ii) To retain at all times, and to use in appropriate instances, keys to all doors within and into the demised premises, and to access the demised premises at any time. Notwithstanding the provisions for Owner’s access to portions of the demised premises, Tenant relieves and releases Owner of all responsibility arising out of theft, robbery and pilferage. Upon the expiration of the Term or of Tenant’s right to possession of the demised premises, Tenant shall return all keys to Owner and shall disclose to Owner the combination of any safes, cabinets or vaults left in the demised premises.

(iii) To designate that window treatments shall consist of blinds adopted by Owner as the standard for the Building and to designate and approve, prior to installation, all types of additional window shades, blinds or draperies.

(iv) Tenant shall not install or operate any equipment or machinery or any mechanical devices of a nature not directly related to Tenant’s ordinary use of the demised premises without the prior written consent of Owner. Movements of Tenant’s property into or out of the Building and within the Building are entirely at the risk and responsibility of Tenant and Owner reserves the right to require permits before allowing any property to be moved into or out of the Building.

(v) To regulate delivery and service of supplies in order to insure the cleanliness and security of the demised premises and to avoid congestion of the loading docks, receiving areas and freight elevators.

(vi) To retain exclusive control and management over all common areas and the roof of the Building, expressly reserving to Owner the right to alter, eliminate, enlarge or otherwise make such changes to the common areas and the roof of the Building as Owner, in its sole discretion, shall deem desirable and, if any such common areas and roof are changed into usable or rentable areas, to retain, for Owner’s own account, all receipts in respect thereof. Owner may operate, manage, equip, light and maintain the common areas and the roof of the Building in such manner as Owner may from time to time determine, and Owner shall have the right and exclusive authority to employ and discharge all personnel with respect thereto. Owner reserves the right to grant to third parties the non-exclusive right to cross over and use in common with Owner and all tenants of the Building such common areas and roof as are designated from time to time by Owner.

57. Notices by Owner’s Agent:

Supplementing the provisions of Article 28 hereof, Tenant agrees that whenever Owner is required or desires to send any notice or other communication to Tenant under or pursuant to this lease, such notice or communication, if sent by one of Owner’s agents (of whose agency Owner shall have advised Tenant), for all purposes shall be deemed to have been sent by Owner. Owner hereby advises Tenant that Owner’s current agent is Rockrose Development Corp., 290 Park Avenue South, New York, New York 10010.

58. Maintenance of Demised Premises:

Owner shall not be responsible for the upkeep or maintenance of the demised premises or any installation or fixtures therein. In no event shall Owner be responsible for or insure any installation, fixtures, betterments or leasehold improvements made by or for the benefit of Tenant. Should Owner hereafter agree, in writing or otherwise, at the request of Tenant or otherwise for repairs or replacements necessitated by Tenant’s acts, negligence or omissions or that of its employees, agents or invitees, to do any work in or in respect of the demised premises, same shall be paid for by Tenant not later than ten (10) days after being billed therefor, at a rate and sum equal to the cost to Owner of any such work plus 10% of such cost.

59. Fees and Expenses:

Whenever any default, request or other action or inaction by Tenant causes Owner to engage an attorney, architect, engineer or other professional and/or incur any other costs or expenses (other than in connection with the negotiation and execution of this Lease), Tenant agrees that it shall pay and/or reimburse Owner for such costs or expenses within ten (10) days after being billed therefor as additional rent. Tenant hereby acknowledges and agrees that Owner may as a condition to the effectiveness of its approval or consent to any request by Tenant require that Tenant reimburse Owner for the amount of any reasonable attorneys’, architects’ and/or engineers’ fees and other costs and expenses incurred by or on behalf of Owner in acting upon or in any manner relating to such request, but that Tenant shall be and remain obligated to reimburse Owner as aforesaid whether or not Owner requires such reimbursement from Tenant as a condition to the effectiveness of any approval or consent and whether or not Owner shall have granted or thereafter grant such approval or consent. Additionally, Tenant shall pay to Owner as additional rent upon demand the amount of all out-of-pocket expenses actually incurred by Owner for field supervision, coordination and general conditions in connection with any alterations, improvements, changes, decorations or additions (collectively, “Work”) done by or on behalf of Tenant in or to the demised premises.

60. Liens:

Tenant shall not create or suffer to be created or to remain, and shall (within thirty (30) days of the filing or imposition thereof) remove or discharge, by bonding or payment, any lien, encumbrance or charge upon the demised premises, the Building or the real property of which the same forms a part caused by or in any manner related to any act or alleged act of commission or omission on the part of Tenant, or any of its agents or contractors. Further, should any such lien be bonded and should Owner, CHC, the City or any of their agents be thereafter named as a party to any action or proceeding in respect of such bond or claim, Tenant agrees to indemnify and save harmless Owner, CHC, the City and all of their agents in respect thereof and to pay all costs and expenses (including reasonable legal fees) of Owner, CHC and the City related thereto. Tenant agrees to surrender the demised premises free and clear of all liens, charges or encumbrances thereon of every nature and description, and free and clear of all violations thereon placed by any governmental or quasi-governmental body resulting from any act of omission or commission on the part of Tenant or any of its agents or contractors, or otherwise related to Tenant’s use or occupancy of the demised premises. Nothing in this lease contained shall be construed as constituting the consent or request of Owner, CHC or the City to any contractor, laborer or materialman for the performance of any labor or services or the furnishing of any materials for the improvement or repair of the demised premises.

61. Alterations:

(a) Before proceeding with any Work Tenant shall, in addition to fulfilling all of its obligations under Article 3 hereof, submit to Owner: (i) a certificate addressed to Owner and CHC from an architect or engineer licensed as such in the State of New York who maintains at least $3,000,000 of insurance (“Tenant’s Architect”) stating that the Work will not reduce the value of the Building, violate any Legal Requirement, affect the exterior walls or appearance of the Building, Carnegie Hall, the connections between the Building and Carnegie Hall or the structural integrity of the Building (including without limitation, the roof of the Building) and estimating the cost of the Work; and (ii) for Owner’s approval (and for submission to CHC if Owner elects),

(o) All bills, invoices or statements rendered to Tenant pursuant to the terms of this lease shall be deemed binding upon Tenant and determined by Tenant to be correct in all respects if, within sixty (60) days after its receipt of same, Tenant fails to notify Owner, in writing, that it disputes such bill, invoice or statement.

(p) Tenant shall not use the words “Carnegie Hall” in any advertising or for any other promotional or profit-making purpose whatsoever and any sublease of all or any part of the demised premises and any assignment of this lease shall contain a provision identical to this Paragraph (p).

Tenant hereby acknowledges that the covenants and agreements in this Paragraph are for the benefit of PDC and the City.

(r) Tenant acknowledges that it has no rights to any development rights, “air rights” or comparable rights appurtenant to the Building, and consents, without further consideration, to any utilization of such rights by Owner, CHC, the City or any third party and agrees to promptly execute and deliver any instruments which may be requested by Owner including, without limitation, instruments merging zoning lots, evidencing such acknowledgement and consent. The provisions of this Paragraph shall be deemed to be and shall be construed as an express waiver by Tenant of any interest Tenant may have as a “party in interest” (as such quoted term is defined in Section 12-10 of the Zoning Resolution of the City).

(s) Tenant hereby agrees that it shall not claim or seek to claim any sales or other tax exemption by reason of the City’s ownership of the Building or the Land. If any sales or other tax is payable with respect to any cleaning or other services which Tenant obtains or contracts for directly from any third party or parties, Tenant shall file any required tax returns and shall pay any such tax, and Tenant shall indemnify and hold Owner harmless from and against any loss, damage or liability suffered or incurred by Owner on account thereof.

(v) In addition to Base Rent, all other payments required to be made by Tenant hereunder shall be deemed to be additional rent, whether or not the same shall be designated as such, and in the event of the non-payment thereof, Owner (in addition to and not in limitation of its other rights and remedies, whether herein reserved or as may be provided by law or in equity) shall have all of the rights and remedies in respect complete plans and specifications for the Work prepared, signed and sealed by Tenant’s Architect and shall obtain Owner’s written approval thereof. Owner’s approval of such plans and specifications (or of any revisions thereto) shall not constitute an opinion or agreement by Owner that the same are structurally sufficient or that they are in compliance with any legal, insurance or other requirements, nor shall any approval impose any present or future liability on Owner, waive any of Owner’s rights or release Tenant of any of its obligations hereunder. Additionally, Owner may, as a condition to granting such approval, require such security as Owner in its reasonable discretion may determine is necessary to ensure the lien free and timely completion of the Work. Tenant shall be solely responsible, once Owner has approved such plans, for obtaining all governmental and quasi governmental approvals thereof and of the Work.

(b) Promptly following the completion of any Work (and, in any event within thirty (30) days thereafter), Tenant shall, at Tenant’s sole cost and expense, deliver to Owner: (i) two (2) sets of “as-built” plans and specifications for the Work; (ii) all original sign offs or other governmental approvals relating thereto; (iii) evidence that the Work has been paid for in full; (iv) copies of Tenant’s records, checks and/or invoices indicating the cost of the Work; (vi) a certification by Tenant’s Architect that all Work was completed in accordance with the plans and specifications approved by Owner; and (vii) a new architectural floor plan showing all demising walls within the demised premises to be in compliance with all laws and any directives issued by the New York City Fire Department with respect to the Building’s fire safety and emergency action plan, which drawing shall be submitted on CD media in CAD (in DWG format) and in PDF copy.

(d) Without incurring any liability to Tenant, Owner may permit access to the demised premises and open same, whether or not Tenant shall be present, upon demand of any receiver, trustee, assignee for the benefit of creditors, sheriff, marshal or court officer entitled to, or reasonably purporting to be entitled to, such access for the purpose of taking possession of, or removing, Tenant’s property or for any other lawful purpose (but this provision and any action by Owner hereunder shall not be deemed a recognition by Owner that the person or official making such demand has any right or interest in or to this lease, or in or to the demised premises), or upon demand of any representative of the fire, police, Building, sanitation or other department of the city, state or federal governments.

(l) The listing of any name other than that of Tenant, whether on the doors of the demised premises, on the Building directory, if any, or otherwise, shall not operate to vest in the named party any right or interest in this lease or in the demised premises, nor shall it be deemed to constitute the consent of Owner to any assignment or transfer of this lease, to any sublease of the demised premises, or to the use or occupancy thereof by others.

(m) In the event of a conflict or inconsistency between the provisions of this rider and the provisions of the printed portion of this lease (comprised of Articles through 36), the provisions of this rider shall in all events govern and prevail.

WITNESSETH:

WHEREAS, by Agreement of Lease, dated as of March 14, 2013, as amended by that certain First Amendment of Lease (the “First Amendment”), dated as of March 11, 2016 (as amended, the “Lease”), Landlord did demise and let unto Tenant and Tenant did hire and take from Landlord a portion of the twenty-first (21st) floor, as more particularly identified in the Lease (the “Original Premises”), of the building known as and by the street address of 152 West 57^th Street, New York, New York (the “Building”); and

WHEREAS, Landlord and Tenant desire to modify the Lease to (i) extend the term of the Lease, (ii) provide for the leasing by Tenant under the Lease of a portion of the tenth (10th) floor of the Building, being more particularly shown on Exhibit A attached hereto (the “Substitute Premises”), (iii) provide for the surrender of the Original Premises, and (iv) otherwise modify the terms and conditions of the Lease, all as hereinafter set forth.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, and of the sum of Ten Dollars ($10.00) paid by Tenant to Landlord, and for other good and valuable consideration, the mutual receipt and legal sufficiency of which are hereby acknowledged, the parties hereto, for themselves, their legal representatives, successors and assigns, hereby agree as follows:

1. Definitions. All capitalized terms used herein shall have the meanings ascribed to them in the Lease, unless otherwise defined herein.

2. Extension of Term. Effective on the date hereof (the “Effective Date”) the term of the Lease is hereby extended on all of the same terms and conditions set forth in the Lease, as hereinafter modified, so that the term of the Lease shall expire on the last day of the month in which the three (3) year anniversary of the Substitute Premises Rent Commencement Date (as hereinafter defined) occurs (the “Second Extended Expiration Date”), provided, however, if the Substitute Premises Rent Commencement Date is the first day of a calendar month, the Second Extended Expiration Date shall be the three (3) year anniversary of the day preceding the Substitute Premises Rent Commencement Date, unless it shall sooner expire pursuant to any of the terms, covenants or conditions of the Lease, as amended by this Amendment, or pursuant to law. All references in the Lease to the Expiration Date and the Extended Expiration Date shall be deemed to refer to the Second Extended Expiration Date.

3. Lease of Original Premises Prior to the Substitute Premises Commencement Date. From and after the Effective Date, Tenant shall continue to lease the Original Premises upon all of the terms and conditions of the Lease and shall continue to pay Base Rent (inclusive of the ERI Sum) at the current rates set forth in the Lease, as the ERI Sum may hereafter be modified pursuant to the terms of the Lease, until the surrender of the Original Premises in accordance with the terms and conditions of Paragraph 5 below.

4. Lease of Substitute Premises. (A) Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the Substitute Premises for a term commencing on the date that Landlord delivers possession of the Substitute Premises to Tenant free of all tenancies and occupants with the work set forth on Exhibit B (the “Landlord’s Substitute Premises Work”) substantially completed (the “Substitute Premises Commencement Date”) and ending on the Second Extended Expiration Date. Notwithstanding anything to the contrary contained herein, in no event shall the Substitute Premises Commencement Date occur prior to March 1, 2018.

(B) Landlord shall not be liable for failure to deliver possession of the Substitute Premises to Tenant on any specified date, and such failure shall not impair the validity of this Amendment. Landlord shall be deemed to have tendered possession of the Substitute Premises to Tenant upon the giving of notice by Landlord to Tenant stating that the Substitute Premises are vacant, in the condition required by this Amendment and available for Tenant’s occupancy. There shall be no postponement of the Substitute Premises Commencement Date for any delay in the delivery of possession of the Substitute Premises to Tenant that results from any Tenant Delay (as hereinafter defined). The provisions of this paragraph are intended to constitute “an express provision to the contrary” within the meaning of Section 223-a of the New York Real Property Law or any successor Legal Requirement. For purposes of this Amendment, “Tenant Delay” shall mean any delay which results from any act or omission of Tenant, including delays due to changes in or additions to, or interference with, any work to be done by Landlord, or delays by Tenant in submission of information, or selecting construction materials to be installed by Landlord as part of Landlord’s Substitute Premises Work, if any, (e.g., color of carpet), or approving working drawings or estimates or giving authorizations or approvals.

(C) Effective as of the Substitute Premises Commencement Date, Tenant shall lease the Substitute Premises upon all of the terms and conditions of the Lease, except as follows:

(i) Tenant shall pay Base Rent with respect to the Substitute Premises (exclusive of the ERI Sum) at the rate of $250,344.00 per annum ($20,862.00 per month) for the period commencing on the Substitute Premises Commencement Date and ending on the Second Extended Expiration Date, both dates inclusive, each payable at the times and in the manner specified in the Lease for the payment of Base Rent. The ERI Sum with respect to the Substitute Premises (x) shall initially be equal to $14,274.00 per annum, (ii) be separately added to the Base Rent and billed on a monthly basis, and (iii) shall be subject to adjustment as provided in Article 39 of the Lease. Notwithstanding the foregoing, provided Tenant is not in default under the Lease or this Amendment, the monthly installments of Base Rent for the Substitute Premises (exclusive of the ERI Sum) for the period commencing on the Substitute Premises Commencement Date to and including the day immediately preceding the one (1) month anniversary of the Substitute Premises Commencement Date shall be abated. The one (1) month anniversary of the Substitute Premises Commencement Date is hereinafter called the “Substitute Premises Rent Commencement Date”.

(ii) Tenant shall continue to pay tax escalations in accordance with the provisions of Article 37 of the Lease except that the definition of “Taxes” set forth in subclause 37(a)(iii) of the Lease shall be amended to read as follows:

“(iii) “Taxes” shall mean (a) an amount during each fiscal year of NYC equal to Tenant’s Proportionate Share (as set forth in the Basic Lease Provisions and as modified pursuant to Paragraph 4(C)(iv) of the Second Amendment to this Lease) of the excess of the product obtained by multiplying the assessed value of the Building and the Land for such fiscal year times the official NYC tax rate applicable to the Building and the Land for such year over the product obtained by multiplying the average assessed value of the Building and the Land, as finally determined, for the fiscal years (i) commencing on July 1, 2017 and continuing through and including June 30, 2018 and (ii) commencing on July 1, 2018 and continuing through and including June 30, 2019, by the official NYC tax rate or rates applicable to the Building and the Land for such period; and (b) Tenant’s Proportionate Share of the legal fees and other expenses (including but not limited to consultants’ and expert witnesses’ fees) paid or incurred in connection with Owner’s obtaining any reduction of such tax rate or the assessed value of the Building and/or the Land for any period during the Term, or both.”

(iii) Tenant shall continue to pay Operating Payments in accordance with the provisions of Article 38 of the Lease, except that effective on the Substitute Premises Commencement Date, the Operating Base Year (as defined in the Basic Lease Provisions) shall be the calendar year 2018 and Tenant’s Proportionate Share shall be as set forth in Paragraph 4(C)(iv) hereof.

(iv) Tenant’s Proportionate Share as defined in the Basic Lease Provisions shall mean 0.772%.

(v) Section 39(g) of the Lease shall be modified and amended to read as follows:

“(g) Owner shall furnish air-conditioning to the demise premises on business days (Mondays through Fridays, Federal, State and union holidays excepted) from 8:00 a.m. to 6:00 p.m. between May 15 and September 15 of each year during the Term. Heat shall be provided by Owner in accordance with the terms of Article 29. Tenant hereby agrees to reimburse Owner, as additional rent, within ten (10) days after demand for 37.40% of the cost incurred by Owner, to maintain and keep in good order, condition and repair the air handling system and all other air conditioning equipment now or at any time serving the tenth (10th) floor in the Building. The Base Rent does not include any charge to Tenant for the furnishing of any heating, ventilation and/or air conditioning (“HVAC”) to the demised premises during any periods other than the hours set forth in this section and in Article 29, as applicable (“Overtime Periods”). If Tenant desires any HVAC service during Overtime Periods, Tenant shall deliver notice to the Building office requesting such services by (i) in the case of such after-hours services on business days, 2:00 P.M. the day such services are to be provided, and (ii) in the case of such after-hours services on non-business days, 12:00PM the business day immediately prior to the day such services are to be provided; provided, however, that Owner shall use reasonable efforts to arrange such service on such shorter notice as Tenant shall provide. If Owner furnishes HVAC service during Overtime Periods, Tenant shall pay to Owner within ten (10) days after demand the cost thereof at the then established rates for such services in the Building. Owner, throughout the Term, shall have free and unrestricted access to all air conditioning equipment and facilities in and/or serving the demised premises and Owner reserves the right to interrupt, curtail, stop or suspend the supply of condenser water when necessary by reason of accident or for repairs, alterations or improvements which are, in the judgment of Owner, desirable or necessary to be made, or by reason of the difficulty or unavailability in securing supplies or labor, strikes, or for any other causes beyond Owner’s control, whether such other causes be similar or dissimilar to those hereinabove specifically mentioned. Furthermore, Owner reserves the right, at any time throughout the Term, to modify, change, reconstruct or alter the air conditioning system or any portion thereof, and the risers, pipes, ducts and conduits used in connection therewith, without affecting the obligations of Tenant hereunder or incurring any liability to Tenant therefor.”

(vi) Article 42 and Article 46 of the Original Lease and Paragraph 5 of the First Amendment shall be deemed not applicable to the leasing of the Substitute Premises.

(vii) Exhibit A of the Original Lease shall be deemed deleted and replaced in its entirety with Exhibit A attached hereto.

(D) Tenant has inspected the Substitute Premises and agrees (A) to accept possession of the Substitute Premises in the “as is” condition existing on the Substitute Premises Commencement Date, (B) that neither Landlord nor Landlord’s agents have made any representations or warranties with respect to the Substitute Premises or the Building except as expressly set forth herein, and (C) except for Landlord’s Substitute Premises Work referred to in Exhibit B attached hereto, Landlord has no obligation to perform any work, supply any materials, incur any expense or make any alterations or improvements to the Substitute Premises to prepare the Substitute Premises for Tenant’s occupancy.

Prior to the Surrender Date, Tenant shall lease the Original Premises upon all of the terms of the Lease applicable to such Original Premises, as amended by this Amendment.

(B) On or before the Surrender Date, time being of the essence with respect to such date, Tenant shall remove all of Tenant’s moveable personal property and moveable trade fixtures from the Original Premises and vacate same and deliver vacant possession thereof to Landlord in the condition required by the Lease.

(E) Landlord shall accept the surrender of the Original Premises as of the Surrender Date and in consideration of such surrender by Tenant and of the acceptance of such surrender by Landlord, Tenant and Landlord do hereby mutually release each other, their respective successors and assigns of and from any and all claims, damages, obligations, liabilities, actions and causes of action, of every kind and nature whatsoever arising under or in connection with the Lease in respect of the Original Premises from and after the Surrender Date, except that nothing herein contained shall be deemed to constitute a release or discharge of Landlord or Tenant with respect to any obligation or liability (i) accrued or incurred under the Lease in respect of the Original Premises and outstanding and unsatisfied on the Surrender Date, and (ii) to a third party (under the insurance and indemnification provisions of the Lease or otherwise) arising prior to, on or after the Surrender Date in respect of the Original Premises as a result of an event occurring or condition existing prior to or on the Surrender Date.
