time of payment, in equal monthly installments in advance on the first day of each month during said term, at the office of Owner or such other place as Owner may designate, without any setoff or deduction whatsoever, except that Tenant shall pay

In the event that, at the commencement of the term of this lease, or thereafter, Tenant shall be in default in the payment of rent to Owner
pursuant to the terms of another lease with Owner or with Owners predecessor in interest, Owner may at Owners option and without notice to Tenant add the amount of such arrears to any monthly installment of rent payable hereunder and the
same shall be payable to Owner as additional rent.

The parties hereto, for themselves, their heirs, distributes, executors,
administrators, legal representatives, successors and assigns, hereby covenant as follows:

Rent:

1. Tenant shall pay the rent as above and as hereinafter provided.

Occupancy:

2. Tenant shall use and occupy the demised premises for.

GENERAL AND EXECUTIVE OFFICES ONLY,      and for no other purpose.



Tenant Alterations: 3. Tenant shall make no changes in or to the demised premises of any nature without Owners prior written consent. Subject to the prior written consent of Owner, and to the provisions of this
article, Tenant, at Tenants expense, may make alterations, installations, additions or improvements which are non-structural and which do not affect utility services or plumbing and electrical lines, in or to the interior of the demised
premises, by using contractors or mechanics first approved in each instance by Owner. [3A] Tenant shall, before making any alterations, additions, installations or improvements, at its expense, obtain all permits, approvals and certificates required
by any governmental or quasi-governmental bodies and (upon completion) certificates of final approval thereof, and shall deliver promptly duplicates of all such permits, approvals and certificates to Owner, and Tenant agrees to carry, and will cause
Tenants contractors and sub-contractors to carry, such workers compensation, commercial general liability, personal and property damage insurance as Owner may require. If any mechanics lien is filed against the demised premises, or
the building of which the same forms a part, for work claimed to have been done for, or materials furnished to, Tenant whether or not done pursuant to this article, the same shall be discharged by Tenant within thirty days [3B]
thereafter, at Tenants expense, by payment or filing a bond as permitted by law. All fixtures and all paneling, partitions, railings and like installations, installed in the demised premises at any time, either by Tenant or by
Owner on Tenants behalf, shall, upon installation, become the property of Owner and shall remain upon and be surrendered with the demised premises unless Owner, by notice to Tenant no later than twenty days prior to the date fixed as the
termination of this lease, elects to relinquish Owners right thereto and to have them removed by Tenant, in which event the same shall be removed from the demised premises by Tenant prior to the expiration of the lease, at Tenants
expense. Nothing in this article shall be construed to give Owner title to, or to prevent Tenants removal of, trade fixtures, moveable office furniture and equipment, but upon removal of same from the demised premises or upon removal, of other
installations as may be required by Owner, Tenant shall immediately, and at its expense, repair and restore the demised premises to the condition existing prior to any such installations, and repair any damage to the demised premises or the building
due to such removal. All property permitted or required to be removed by Tenant at the end of the term remaining in the demised premises after Tenants removal shall be deemed abandoned and may, at the election of Owner, either be retained as
Owners property or may be removed from the demised premises by Owner, at Tenants expense.[3C] Maintenance and Repairs: 4. Tenant shall, throughout the term of this lease, take good care of the demised premises and the fixtures and
appurtenances therein. Tenant shall be responsible for all damage or injury to the demised premises or any other part of the building and the systems and equipment thereof, whether requiring structural or nonstructural repairs caused by, or
resulting from, carelessness, omission, neglect or improper conduct of Tenant, Tenants subtenants, agents, employees, invitees or licensees, or which arise out of any work, labor, service or equipment done for, or supplied to, Tenant or any
subtenant, or arising out of the installation, use or operation of the property or equipment of Tenant or any subtenant. Tenant shall also repair all damage to the building and the demised premises caused by the moving of Tenants fixtures,
furniture and equipment. Tenant


shall promptly make, at Tenants expense, all repairs in and to the demised premises for which Tenant
is responsible, using only [4A] the contractor for the trade or trades in question, selected from a list of at least two contractor per trade submitted by Owner. Any other repairs in or to the building or the facilities and systems
thereof, for which Tenant is responsible, shall be performed by Owner at the Tenants expense. Owner shall maintain in good working order and repair the exterior and the structural portions of the building, including the structural portions of
the demised premises, and the public portions of the building interior and the building plumbing, electrical, heating and ventilating systems (to the extent such systems presently exist) serving the demised premises. Tenant agrees to give prompt
notice of any defective condition in the demised premises for which Owner may be responsible hereunder. There shall be no allowance to Tenant for diminution of rental value [4B] and no liability on the part of Owner by reason of inconvenience,
annoyance or injury to business arising from Owner or others making repairs, alterations, additions or improvements in or to any portion of the building or the demised premises, or in and to the fixtures, appurtenances or equipment thereof. It is
specifically agreed that Tenant shall not be entitled to any setoff or reduction of rent by reason of any failure of Owner to comply with the covenants of this or any other article of this lease. Tenant agrees that Tenants sole remedy at law
in such instance will be by way of an action for damages for breach of contract. The provisions of this Article 4 shall not apply in the case of fire or other casualty, which are dealt with in Article 9 hereof. Window Cleaning: 5.
Tenant will not clean nor require, permit, suffer or allow any window in the demised premises to be cleaned from the outside in violation of Section 202 of the Labor Law or any other applicable law, or of the Rules of the Board of Standards and
Appeals, or of any other Board or body having or asserting jurisdiction. Requirements of Law, Fire Insurance, Floor Loads: 6. Prior to the commencement of the lease term, if Tenant is then in possession, and at all times thereafter, Tenant, at Tenants
sole cost and expense, shall [6A] promptly comply with all present and future laws, orders and regulations of all state, federal, municipal and local governments, departments, commissions and boards and any direction of any public officer pursuant
to law, and all orders, rules and regulations of the New York Board of Fire Underwriters, Insurance Services Office, or any similar body which shall impose any violation, order or duty upon Owner or Tenant with respect to the demised premises, [6B]
whether or not arising out of Tenants use or manner of use thereof, (including Tenants permitted use) or, with respect to the building if arising out of Tenants use or manner of use of the demised premises or the building
(including the use permitted under the lease). [6C] Nothing herein shall require Tenant to make structural repairs or alterations unless Tenant has, by its manner of use of the demised premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto. Tenant may, after securing Owner to Owners satisfaction against all damages, interest, penalties and expenses, including, but not limited to, reasonable
attorneys fees, by cash deposit or by surety bond in an amount and in a company satisfactory to Owner, contest and appeal any such laws, ordinances, orders, rules, regulations or requirements provided same is done with all reasonable
promptness and




---

provided such appeal shall not subject Owner to prosecution for a criminal offense, or constitute a default under any lease or mortgage under which Owner may be obligated, or cause the demised
premises or any part thereof to be condemned or vacated. Tenant shall not do or permit any act or thing to be done in or to the demised premises which is contrary to law, or which will invalidate or be in conflict with public liability, fire or
other policies of insurance at any time carried by or for the benefit of Owner with respect to the demised premises or the building of which the demised premises form a part, or which shall or might subject Owner to any liability or responsibility
to any person, or for property damage. Tenant shall not keep anything in the demised premises, except as now or hereafter permitted by the Fire Department, Board of Fire Underwriters, Fire Insurance Rating Organization or other authority having
jurisdiction, and then only in such manner and such quantity so as not to increase the rate for fire insurance applicable to the building, nor use the demised premises in a manner which will increase the insurance rate for the building or any
property located therein over that in effect prior to the commencement of Tenants occupancy. Tenant shall pay all costs, expenses, fines, penalties, or damages, which may be imposed upon Owner by reason of Tenants failure to comply with
the provisions of this article, and if by reason of such failure the fire insurance rate shall, at the beginning of this lease, or at any time thereafter, be higher than it otherwise would be, then, Tenant shall reimburse Owner, as additional rent
hereunder, for that portion of all fire insurance premiums thereafter paid by Owner which shall have been charged because of such failure by Tenant. In any action or proceeding wherein Owner and Tenant are parties, a schedule or make-up
of rate for the building or the demised premises issued by the New York Fire Insurance Exchange, or other body making fire insurance rates applicable to said premises shall be conclusive evidence of the facts therein stated and of the several items
and charges in the fire insurance rates then applicable to said premises. Tenant shall not place a load upon any floor of the demised premises exceeding the floor load per square foot area which it was designed to carry and which is allowed by law.
Owner reserves the right to prescribe the weight and position of all safes, business machines and mechanical equipment. Such installations shall be placed and maintained by Tenant, at Tenants expense, in settings sufficient, in Owners
judgment, to absorb and prevent vibration, noise and annoyance. Subordination: 7. This lease is subject and subordinate to all ground or underlying leases and to all mortgages which may now or hereafter affect such
leases or the real property of which the demised premises are a part, and to all renewals, modifications, consolidations, replacements and extensions of any such underlying leases and mortgages. This clause shall be self-operative and no further
instrument of subordination shall be required by any ground or underlying lessor or by any mortgagee, affecting any lease or the real property of which the demised premises are a part. In confirmation of such subordination, Tenant shall from time to
time execute promptly any certificate that Owner may request. Property Loss, Damage Reimbursement Indemnity: 8. Owner or its agents shall not be liable for any damage to property of Tenant or of others entrusted to employees of the building, nor
for loss of or damage to any property of Tenant by theft or otherwise, nor for any injury or damage to persons or property resulting from any cause of whatsoever nature, unless caused by, or due to, the negligence of Owner, its agents, servants or
employees. Owner or its agents will not be liable for any such damage caused by other tenants or persons in, upon or about said building, or caused by operations in construction of any private, public or quasi public work. If at any time any windows
of the demised premises are temporarily closed, darkened or bricked up [8A] (or permanently closed, darkened or bricked up, if required by law) for any reason whatsoever including, but not limited to, Owners own acts, Owner
shall not be liable for any damage Tenant may sustain thereby, and Tenant shall not be entitled to any compensation therefore, nor abatement or dimination of reat, nor shall the same release Tenant from its obligations hereunder, nor constitute an
eviction. Tenant shall indemnify and save harmless Owner against and from all liabilities, obligations, damages, penalties, claims, costs and expenses for which Owner shall not be reimbursed by insurance, including reasonable attorneys fees,
paid, suffered or incurred as a result of any breach by Tenant, Tenants agents, contractors, employees, invitees, or licensees, of any covenant or condition of this lease, or the carelessness, negligence or improper conduct of the Tenant,
Tenants agents, contractors, employees, invitees or licensees. Tenants liability under this lease extends to the acts and omissions of any subtenant, and any agent, contractor, employee, invitee or licensee of any subtenant. In case any
action or proceeding is brought against Owner by reason of any such claim, Tenant, upon written notice front Owner, will, at Tenants expense, resist or defend such action or proceeding by counsel approved by Owner in writing, such approval not
to be unreasonably withheld. Destruction, Fire and Other Casualty: 9. (a) If the demised premises or any part thereof shall be damaged by fire or other casualty, [9A] Tenant shall give immediate notice
thereof to Owner, and this lease shall continue in full force and effect except as hereinafter set forth. (b) If the demised premises are partially damaged or rendered partially unusable by fire or other casualty, the damages thereto shall be
repaired by, and at the expense of, Owner, and the rent and other items of additional rent, until such repair shall be substantially completed, shall be apportioned from the day following the casualty, according to the part of the demised premises
which is usable. (c) If the demised premises are totally damaged or rendered wholly unusable by fire or other casualty, then the rent and other items of additional rent, as hereinafter expressly provided, shall be proportionately paid up to the
time of the casualty, and thenceforth shall cease until the date when the demised premises shall have been repaired and restored by Owner (or if sooner reoccupied in part by the Tenant then rent shall be apportioned as provided in subsection
(b) above), subject to Owners right to elect not to restore the same as hereinafter provided. (d) If the demised premises are rendered wholly unusable or (whether or not the demised premises are damaged in whole or in part) if the
building shall be so damaged that Owner shall decide to demolish it or to rebuild it, then, in any of such events, Owner may elect to terminate this lease by written notice to Tenant, given within ninety (90) days after such fire or casualty,
or thirty (30) days after adjustment of the insurance claim for such fire or casualty, whichever is sooner, specifying a date for the expiration of the lease, which date shall not be more than sixty (60) days after the giving of such
notice, and upon the date specified in such


notice the term of this lease shall expire as fully and completely as if such date were the date set forth above for the termination of this lease, and Tenant shall forthwith quit, surrender and
vacate the demised prentices without prejudice however, to Landlords rights and remedies against Tenant under the lease provisions in effect prior to such termination, and any rent owing shall be paid up to such date, and any payments of rent
made by Tenant which were on account of any period subsequent to such date shall be returned to Tenant. Unless Owner shall serve a termination notice as provided for herein, Owner shall make the repairs and restorations under the conditions of
(b) and (c) hereof, with all reasonable expedition, subject to delays due to adjustment of insurance claims, labor troubles and causes beyond Owners control. After any such casualty, Tenant shall cooperate with Owners
restoration by removing from the demised premises as promptly as reasonably possible, all of Tenants salvageable inventory and movable equipment, furniture, and other property. Tenants liability for rent shall resume five (5) days
after written notice from Owner that demised premises are substantially ready for Tenants occupancy. (e) Nothing contained hereinabove shall relieve Tenant from liability that may exist as a result of damage from fire or other casualty.
Notwithstanding anything contained to the contrary in subdivisions (a) through (e) hereof, including Owners obligation to restore under subparagraph (b) above, each party shall look first to any insurance in its favor before
making any claim against the other party for recovery for loss or damage resulting from fire or other casualty, and to the extent that such insurance is in force and collectible, and to the extent permitted by law, Owner and Tenant each hereby
releases and waives all right of recovery with respect to subparagraphs (b), (d), and (e) above, against the other, or any one claiming through or under each of them by way of subrogation or otherwise. The release and waiver herein referred to
shall be deemed to include any loss or damage to the demised premises and/or to any personal property, equipment, trade fixtures, goods and merchandise located therein. The foregoing release and waiver shall be in force only if both releasors
insurance policies contain a clause providing that such a release or waiver shall not invalidate the insurance. [9B] If, and to the extent, that such waiver can be obtained only by the payment of additional premiums, then the party benefiting from
the waiver shall pay such premium within ten days after written demand or shall be deemed to have agreed that the party obtaining insurance coverage shall be free of any further obligation under the provisions hereof with respect to waiver of
subrogation. Tenant acknowledges that Owner will not carry insurance on Tenants furniture and/or furnishings or any fixtures or equipment, improvements, or appurtenances removable by Tenant, and agrees that Owner will not be obligated to
repair any damage thereto or replace the same: [9C] (f) Tenant hereby waives the provisions of section 227 of the Real Property Law and agrees that the provisions of this article shall govern and control in lieu thereof. [9D] Eminent Domain: 10. If
the whole or any part of the demised premises shall be acquired or condemned by Eminent Domain for any public or quasi public use or purpose, then, and in that event, the term of this lease shall cease and terminate from the date of title vesting in
such proceeding, and Tenant shall have no claim for the value of any unexpired term of said lease, and assigns to Owner, Tenants entire interest in any such award. Tenant shall have the right to make an independent claim to the condemning
authority for the value of Tenants moving expenses and personal property, trade fixtures and equipment, provided Tenant is entitled pursuant to the terms of the lease to remove such property, trade fixtures and equipment at the end of the
term, and provided further such claim does not reduce Owners award. Assignment, Mortgage, Etc.: 11. Tenant, for itself, its heirs, distributes, executors, administrators, legal representatives, successors and assigns, expressly
covenants that it shall not assign, mortgage or encumber this agreement, nor underlet, or suffer or permit the demised premises or any part thereof to be used by others, without the prior written consent of Owner in each instance [11A]. Transfer of
the majority of the stock of a corporate Tenant or the majority interest in any partnership or other legal entity which is Tenant shall be deemed an assignment. If this lease be assigned, or if the demised premises or any part thereof be underlet or
occupied by anybody other than Tenant, Owner may, after default by Tenant, collect rent from the assignee, under-tenant or occupant, and apply the net amount collected to the rent herein reserved, but no such assignment, underletting, occupancy or
collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, undertenant or occupant as tenant, or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained. The
consent by Owner to an assignment or underletting shall not in any way be construed to relieve Tenant from obtaining the express consent in writing of Owner to any further assignment or underletting. Electric Current:


LOGO 12. Rates and conditions in respect to submetering or rent inclusion, as the case may be,
to be added in RIDER attached hereto, Tenant covenants and agrees that at all times its use of electric current shall not exceed the capacity of existing feeders to the building or the risers or wiring installation, and Tenant may not use any
electrical equipment which, in Owners opinion, reasonably exercised, will overload such installations or interfere with the use thereof by other tenants of the building. The change at any time of the character of electric service shall in no
way make Owner liable or responsible to Tenant, for any loss, damages or expenses which Tenant may sustain. Access to Premises: 13. Owner or Owners agents shall have the right (but shall not be obligated) to enter the demised premises in any
emergency at any time, and, at other reasonable times [13A], to examine the same and to make such repairs, replacements and improvements as Owner may deem necessary and reasonably desirable to the demised premises or to any other portion of the
building or which Owner may elect to perform. [13B] Tenant shall permit Owner to use and maintain and replace pipes, ducts, and conduits in and through the demised premises and to erect new pipes, ducts, and conduits therein, provided they are
concealed within the walls, floor, or ceiling. Owner may, during the progress of any work in the demised premises, take all necessary materials and equipment into said premises without the same constituting an eviction, nor shall the Tenant be
entitled to any abatement of rent while such work is in progress, nor to any damages by reason of loss or interruption of business or otherwise. Throughout the term hereof, Owner shall have the right to enter the demised premises at reasonable hours
for

the purpose of showing the same to prospective purchasers or mortgagees of the building, and during the
last six months of the term, for the purpose of showing the same to prospective tenants. If Tenant is not present to open and permit an entry into the demised premises, Owner or Owners agents may enter the same whenever such entry may be
necessary or permissible by master key or forcibly, and provided reasonable care is exercised to safeguard Tenants property, such entry shall not render Owner or its agents liable therefore, nor in any event shall the obligations of Tenant
hereunder be affected. If during the last month of the term Tenant shall have removed all or substantially all of Tenants property therefrom, Owner may immediately enter, alter, renovate or redecorate the demised premises without limitation or
abatement of rent, or incurring liability to Tenant for any compensation, and such act shall have no effect on this lease or Tenants obligations hereunder. Vault, Vault Space, Area: 14. No vaults, vault space or area, whether or
not enclosed or covered, not within the property line of the building, is leased hereunder, anything contained in or indicated on any sketch, blue print or plan, or anything contained elsewhere in this lease to the contrary notwithstanding. Owner
makes no representation as to the location of the property line of the building. All vaults and vault space and all such areas not within the property line of the building, which Tenant may be permitted to use and/or occupy, is to be used and/or
occupied under a revocable license, and if any such license be revoked, or if the amount of such space or area be diminished or required by any federal, state or municipal authority or public utility. Owner shall not be subject to any liability, nor
shall Tenant be entitled to any compensation or diminution or abatement of rent, nor shall such revocation, diminution or requisition be deemed constructive or actual eviction. Any tax, fee or charge of municipal authorities for such vault or area
shall be paid by Tenant. Occupancy: 15. [15A] Tenant will not at any time use or occupy the demised premises in violation of the certificate of occupancy issued for the building of which the demised premises are a part. Tenant has inspected
the demised premises and accepts them as is, subject to the riders annexed hereto with respect to Owners work, if any. In any event, Owner makes no representation as to the condition of the demised premises, [15B] and Tenant agrees accept the
same subject to violations, whether or not of record. [15C] Bankruptcy: 16. (a) Anything elsewhere in this lease to the contrary notwithstanding, this lease may be cancelled by Owner by the sending of a
written notice to Tenant within a reasonable time after the happening of any one or more of the following events; (1) the commencement of a case in bankruptcy or under the laws of any state naming Tenant (or a guarantor of any Tenants
obligations under this lease) as the debtor; or (2) the making by Tenant (or a guarantor of any of Tenants obligations under this lease) of an assignment or any other arrangement for the benefit of creditors under any state statute.
Neither Tenant nor any person claiming through or under Tenant, or by reason of any statute or order of court, shall thereafter be entitled to possession of the premises demised but shall forthwith quit and surrender the demised premises. If this
lease shall be assigned in accordance with its terms, the provisions of this Article 16 shall be applicable only to the party then owning Tenants interest in this lease. (b) It is stipulated and agreed that in the event of the termination of this lease pursuant to (a) hereof, Owner shall forthwith,
notwithstanding any other provisions of this lease to the contrary, be entitled to recover from Tenant as and for liquidated damages, an amount equal to the difference between the rent reserved hereunder for the unexpired portion of the term demised
and the fair and reasonable rental value of the demised premises for the same period. In the computation of such damages the difference between any installment of rent becoming due hereunder after the date of termination, and the fair and reasonable
rental value of the demised premises for the period for which such installment was payable, shall be discounted to the date of termination at the rate of four percent (4%) per annum. If such demised premises or any part thereof be re-let by the
Owner for the unexpired term of said lease, or any part thereof, before presentation of proof of such liquidated damages to any court, commission or tribunal, the amount of rent reserved upon such re-letting shall be deemed to be the fair and
reasonable rental value for the part or the whole of the demised premises so re-let during the term of the re-letting. Nothing herein contained shall limit or prejudice the right of the Owner to prove for and obtain as liquidated damages, by reason
of such termination, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved, whether or not such amount be greater, equal to, or less
than, the amount of the difference referred to above. Default: 17. If Tenant defaults in fulfilling any of the covenants of this lease other than the covenants for the payment of rent or additional
rent; or if the demised premises become vacant or deserted; or if any execution or attachment shall be issued against Tenant or any of Tenants property, whereupon the demised premises shall be taken or occupied by someone other than Tenant; or
if this lease be rejected under §365 of Title II of the U.S. Code (Bankruptcy Code); or if Tenant shall have failed, after five (5) days written notice, to redeposit with Owner any portion of the security deposit hereunder which Owner has
applied to the payment of any rent and additional rent due and payable hereunder; or if Tenant shall be in default with respect to any other lease between Owner and Tenant; or if Tenant shall fail to move into or take possession of the demised
premises within thirty (30) days after the commencement of the term of this lease, then, in any one or more of such events, upon Owner serving a written [17A] fifteen (15) days notice upon Tenant specifying the nature of
said default, and upon the expiration of said [17B] fifteen (15) days, if Tenant shall have failed to comply with or remedy such default, or if the said default or omission complained of shall be of a nature that the same
cannot be completely cured or remedied within said [17C] fifteen (15) day period, and if Tenant shall not have diligently commenced curing such default within such [17D] fifteen (15) day period, and shall
not thereafter with reasonable diligence and in good faith, proceed to remedy or cure such default, then Owner may serve a written five (5) days notice of cancellation of this lease upon Tenant, and upon the expiration of said five
(5) days this lease and the term thereunder shall end and expire as fully and completely as if the expiration of such five (5) day period were the day herein definitely fixed for the end and expiration of this lease and the term thereof,
and Tenant shall then quit and surrender the demised premises to Owner, but Tenant shall remain liable as hereinafter provided.


(2) If the notice provided for in (1) hereof shall have been given, and the term
shall expire as aforesaid; or if Tenant shall make default in the payment of the rent reserved herein, or any item of additional rent herein mentioned, or any part of either, or in making any other payment herein required; then, and in any of such
events. Owner may without notice, re-enter the demised premises either by force or otherwise, and dispossess Tenant by summary proceedings or otherwise, and the legal representative of Tenant or other occupant of the demised premises, and remove
their effects and hold the demised premises as if this lease had not been made, and Tenant hereby waives the service of notice of intention to re-enter or to institute legal proceedings to that end. If Tenant shall make default hereunder prior to
the date fixed as the commencement of any renewal or extension of this lease, Owner may cancel and terminate such renewal or extension agreement by written notice. Remedies of Owner and Waiver of Redemption: 18. In case of any such
default, re-entry, expiration and/or dispossess by summary proceedings or otherwise, (a) the rent shall become due thereupon and be paid up to the time of such re-entry, dispossess and/or expiration, (b) Owner may re-let the demised
premises or any part or parts thereof, either in the name of Owner or otherwise, for a term or terms, which may at Owners option be less than or exceed the period which would otherwise have constituted the balance of the term of this lease,
and may grant concessions or free rent or charge a higher rental than that in this lease, and/or (c) Tenant or the legal representatives of Tenant shall also pay to Owner as liquidated damages for the failure of Tenant to observe and perform
said Tenants covenants herein contained, any deficiency between the rent hereby reserved and/or covenamed to be paid and the net amount if any, of the rents collected on account of the lease or leases of the demised premises for each month of
the period which would otherwise have constituted the balance of the term of this lease. The failure of Owner to re-let the demised premises, or any part or parts thereof, shall not release or affect Tenants liability for damages. In computing
such liquidated damages there shall be added to the said deficiency such expenses as Owner may incur in connection with re-letting, such as legal expenses, reasonable attorneys fees, brokerage, advertising and for keeping the demised premises
in good order or for preparing the same for re-letting. Any such liquidated damages shall be paid in monthly installments by Tenant on the rent day specified in this lease, and any suit brought to collect the amount of the deficiency for any month
shall not prejudice in any way the rights of Owner to collect the deficiency for any subsequent month by a similar proceeding. Owner, in putting the demised premises in good order or preparing the same for re-rental may, at Owners option, make
such alterations, repairs, replacements, and/or decorations in the demised premises as Owner, in Owners sole judgment, considers advisable and necessary for the purpose of re-letting the demised premises, and the making of such alterations,
repairs, replacements, and/or decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Owner shall in no event be liable in any way whatsoever for failure to re-let the demised premises, or in the event
that the demised premises are re-let, for failure to collect the rent thereof under such re-letting, and in no event shall Tenant be entitled to receive any excess, if any, of such net rents collected over the sums payable by Tenant to Owner
hereunder. In the event of a breach or threatened breach by Tenant of any of the covenants or provisions hereof, Owner shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if re-entry, summary
proceedings and other remedies were not herein provided for. Mention in this lease of any particular remedy, shall not preclude Owner from any other remedy, in law or in equity. Tenant hereby expressly waives any and all rights of redemption granted
by or under any present or future laws in the event of Tenant being evicted or dispossessed for any cause, or in the event of Owner obtaining possession of the demised premises, by reason of the violation by Tenant of any of the covenants and
conditions of this lease, or otherwise. Fees and Expenses: 19. If Tenant shall default in the observance or performance of any term or covenant on Tenants part to be observed or performed
under, [19A] or by virtue of, any of the terms or provisions in any article of this lease; after notice, if required, and upon expiration of any applicable grace period, if any (except in an emergency), then, unless otherwise
provided elsewhere in this lease. Owner may immediately, or at any time thereafter and without notice, perform the obligation of Tenant thereunder. If Owner, in connection with the foregoing, or in connection with any default by Tenant in the
covenant to pay rent hereunder, makes any expenditures or incurs any obligations for the payment of money, including but not limited to reasonable attorneys fees, in instituting, prosecuting or defending any action or proceeding, and prevails
in any such action or proceeding, then Tenant will reimburse Owner for such sums so paid, or obligations incurred, with interest and costs. The foregoing expenses incurred by reason of Tenants default shall be deemed to be additional rent
hereunder, and shall be paid by Tenant to Owner within ten (10) days of rendition of any bill or statement to Tenant therefore. If Tenants lease term shall have expired at the time of making of such expenditures or incurring of such
obligations, such sums shall be recoverable by Owner, as damages. [19B] Building Alterations and Management: 20. Owner shall have the right at any time without the same constituting an eviction and without incurring liability to Tenant therefore,
to change the arrangement and/or location of public entrances, passageways, doors, doorways, corridors, elevators, stairs, toilets or other public parts of the building and to change the name, number or designation by which the building may be
known. There shall be no allowance to Tenant for diminution of rental value and no liability on the part of Owner by reason of inconvenience, annoyance or injury to business arising from Owner or other Tenants making any repairs in the building or
any such alterations, additions and improvements. [20A] Furthermore, Tenant shall not have any claim against Owner by reason of Owners imposition of such controls of the manner of access to the building by Tenants social or business
visitors as the Owner may deem necessary for the security of the building and its occupants. No Representations Owner: 21. Neither Owner nor Owners agents have made any representations or promises with respect to the physical condition of the building,
the land upon which it is erected or the demised premises, the rents, leases, expenses of operation or any other matter or thing affecting or related to the demised premises, except as herein




---

expressly set forth, and no rights, easements or licenses are acquired by Tenant by implication or
otherwise, except as expressly set forth in the provisions of this lease. Tenant has inspected the building and the demised premises and is thoroughly acquainted with their condition and agrees to take the same as-is, and acknowledges
that the taking of possession of the demised premises by Tenant shall be conclusive evidence that the said premises and the building of which the same form a part were in good and satisfactory condition at the time such possession was so taken,
except as to latent defects. All understandings and agreements heretofore made between the parties hereto are merged in this contract, which alone fully and completely expresses the agreement between Owner and Tenant, and any executory agreement
hereafter made shall be ineffective to change, modify, discharge or effect an abandonment of it in whole or in part, unless such executory agreement is in writing and signed by the party against whom enforcement of the change, modification,
discharge or abandonment is sought. End of Term: 22. Upon the expiration or other termination of the term of this lease, Tenant shall quit and surrender to Owner the demised premises, broom-clean, in good order and condition, ordinary wear
and damages which Tenant is not required to repair as provided elsewhere in this lease excepted, and Tenant shall remove all its property. Tenants obligation to observe or perform this covenant shall survive the expiration or other termination
of this lease. If the last day of the term of this lease or any renewal thereof, falls on Sunday, this lease shall expire at noon on the preceding Saturday, unless it be a legal holiday, in which case it shall expire at noon on the preceding
business day. Quiet Enjoyment: 23. Owner covenants and agrees with Tenant that upon Tenant paying the rent and additional rent and observing and performing all the terms, covenants and conditions, on Tenants part to be observed
and performed. Tenant may peaceably and quietly enjoy the premises hereby demised, subject, nevertheless, to the terms and conditions of this lease including, but not limited to, Article 31 hereof, and to the ground leases, underlying leases and
mortgages hereinbefore mentioned. 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 way 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. If permission is given to Tenant to enter into possession of the demises premises, or
to occupy premises other than the demised premises, prior to the date specified as the commencement of the term of this lease. Tenant covenants and agrees that such possession and/or occupancy shall be deemed to be under all the terms, covenants,
conditions and provisions of this lease, except the obligation to pay the fixed annual rent set forth in the preamble to this lease. The provisions of this article are intended to constitute an express provision to the contrary within
the meaning of Section 223-a of the New York Real Property Law. No Waiver: 25. The failure of Owner to seek redress for violation of, or to insist upon the strict performance of, any covenant or condition of this
lease or of any of the Rules or Regulations, set forth or hereafter adopted by Owner, shall not prevent a subsequent act which would have originally constituted a violation from having all the force and effect of an original violation. The receipt
by Owner of rent and/or additional rent with knowledge of the breach of any covenant of this lease shall not be deemed a waiver of such breach, and no provision of this lease shall be deemed to have been waived by Owner unless such waiver be in
writing signed by Owner. No payment by Tenant or receipt by Owner of a lesser amount that 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. It is further mutually agreed that in the event Owner commences any proceeding or action for possession,
including a summary proceeding for possession of the demised premises, Tenant will not interpose any counterclaim of whatever nature or description in any such proceeding, including a counterclaim under Article 4, except for statutory mandatory
counterclaims. [26A] Inability to Perform: 27. This lease and the obligation of Tenant to pay rent hereunder and perform all of the other covenants and agreements hereunder on part of Tenant to be performed shall in no way be affected, impaired or
excused because Owner is unable to fulfill any of its obligations under this lease, or to supply, or is delayed in supplying, any service expressly or impliedly to


be supplied, or is unable to make, or is delayed in making, any repair, additions, alterations, or
decorations, or is unable to supply, or is delayed in supplying, any equipment, fixtures, or other materials, if Owner is prevented or delayed from so doing by reason of strike or labor troubles or any cause whatsoever including, but not limited to,
government preemption or restrictions, or by reason of any rule, order or regulation of any department or subdivision thereof of any government agency, or by reason of the conditions which have been or are affected, either directly or indirectly, by
war or other emergency. Bills and Notices: 28. Except as otherwise in this lease provided, any notice, statement, demand or other communication required or permitted to be given, rendered or made by either party to the other, pursuant to this
lease or pursuant to any applicable law or requirement of public authority, shall be in writing (whether or not so stated elsewhere in this lease) and shall be deemed to have been properly given, rendered or made, if sent by registered or certified
mail (express mail, if available), return receipt requested, or by courier guaranteeing overnight delivery and furnishing a receipt in evidence thereof, addressed to the other party at the address hereinabove set forth (except that after the date
specified as the commencement of the term of this lease, Tenants address, unless Tenant shall give notice to the contrary, shall be the building), and shall be deemed to have been given, rendered or made (a) on the date delivered, if delivered
to Tenant personally, (b) on the date delivered, if delivered by overnight courier or (c) on the date which is two (2) days after being mailed. Either party may, by notice as aforesaid, designate a different address or addresses for notices,
statements, demand or other communications intended for it. Notices given by Owners managing agent shall be deemed a valid notice if addressed and set in accordance with the provisions of this Article. At Owners option, notices and bills
to Tenant may be sent by hand delivery. Services Provided by Owner: 29. As long as Tenant is not in default under any of the covenants of this lease beyond the applicable grace period provided in this lease
for the curing of such defaults, Owner shall provide: (a) necessary elevator facilities on business days from 8 a.m. to 6 p.m. and have one elevator subject to call at all other times; (b) heat to the demised premises when and as required by law, on

when bills are rendered; (d) cleaning service for the demised premises on business days at Owners expense provided that the same are kept in order by Tenant. If, however, said premises are to be kept clean by Tenant, it shall be done at

buildings in New York City and the requirement for compliance with such Requirement does not arise by reason of (i) the abatement of any nuisance in, on or about the Demised Premises caused by Tenant, its agents, employees, contractors, guests
or anyone claiming by, through or under Tenant, (ii) the particular manner of conduct of Tenants business or operation of its installations, equipment or other property therein, including, without limitation, the performance of any work

|9C | For purposes of clarity, any provision contained in this Article 9, Article 10 or elsewhere in this lease providing for the apportionment or abatement of Rent, unless
such abatement specifies that only Fixed Rent or only Additional Charges, or a component thereof shall be abated (e.g., Section 37(c), which provides an abatement of Fixed Rent only and not of the electricity component of Fixed Rent or any
Additional Charges), shall mean that such abatement includes all Fixed Rent and Additional Charges.

(a) As soon as reasonably practicable, but in any event no later than sixty (60) days following the date of any fire or other casualty rendering any portion of the Demised Premises untenantable, Owner
shall notify Tenant of Owners good faith best estimate of the date (the Estimated Date) by which the repair and restoration necessary to render the Demised Premises no longer untenantable can be completed
(Owners Repair Notice). Notwithstanding anything herein to the contrary, if, by reason of a fire or other casualty, (A) (l) more than fifty (50%) percent of the rentable square footage of the Demised Premises
shall be damaged or destroyed and rendered untenantable (or, in the case of damage or destruction to the public portions of the Building necessary for access to the Demised Premises, more than fifty (50%) percent of the rentable square footage
of the Demised Premises shall be rendered untenantable) and (2) the Estimated Date set forth in Owners Repair Notice with respect to such fire or other casualty is after the date (the Outside Repair Date) which is the
nine (9) month anniversary of the date of such fire or other casualty (a fire or other casualty meeting the requirements of the preceding subclauses (l) and (2) being a Substantial Casualty) or (B) more than
twenty-five (25%) percent of the rentable square footage of the Demised Premises is rendered untenantable during the last 12 months of the term of this lease, then Tenant shall have a one time only right (except as set forth in subsection
(b) below) to terminate this lease by notice (the Damage Termination Notice) given to Owner within thirty (30) days following Owners giving of Owners Repair Notice. Such termination shall be effective as of
the date which is thirty (30) days after the Damage Termination Notice, and, upon delivery of such notice and the expiration of such 30-day period, this lease and the term hereof shall expire as fully and completely as if such date were the
date originally set forth for the termination of this lease. Tenants failure to deliver the Damage Termination Notice in the time and manner required by this subclause (a) shall be deemed an irrevocable waiver of Tenants right to
terminate this lease pursuant to this subclause (a).

(b) In addition, in the event of any Substantial
Casualty, if the repair or restoration necessary to render the Demised Premises no longer untenantable is not substantially completed by the Outside Repair Date, as such Outside Repair Date shall be extended due to delays caused or occasioned by
Owners inability to perform (as described in Article 27 hereof) or by Tenant, its agents, employees, contractors, architects, engineers or servants, then Tenant shall be entitled to terminate this lease by a Damage Termination Notice given to
Owner within thirty (30) days after the Outside Repair Date (as so extended) and, upon the giving of such notice, this lease and the term hereof shall expire effective on the thirtieth (30th) day after the giving of such notice (the Damage Termination Date);
provided, however, if Tenant delivers a Damage

Termination Notice pursuant to this subclause (b) to Owner, then Owner shall have the right to suspend the occurrence of the Damage Termination Date for a period of thirty (30) days
after the date of the Damage Termination Notice by delivering to Tenant, within ten (10) Business Days after Owners receipt of such Damage Termination Notice, a certificate of Owners contractor responsible for the repairs of such
damage certifying that it is such contractors good faith judgment that the repairs shall be substantially completed within thirty (30) days after the date of the Damage Termination Notice. If the repairs shall be substantially completed
prior to the expiration of such thirty (30) day period, the Damage Termination Notice shall be null and void and of no force or effect, and this lease shall continue, but if the repairs shall not be substantially completed within such thirty
(30) day period, then this lease shall terminate upon the expiration of such thirty (30) day period.

Date) or on such earlier date upon which the term of this lease shall expire or be canceled or terminated pursuant to any of the terms, conditions or covenants of this lease or pursuant to law.

(ii) Notwithstanding the provisions of Section 37(a)(i) above,

(A) Tenant may have access to the Demised Premises prior to the Substantial Completion Date for the sole purpose of taking measurements and
installing cables and wiring for Tenants telephone, computer and data systems to the extent customarily performed by tenants during the initial build-out of a premises (but not the systems themselves, which Tenant may install after the
Commencement Date) (collectively, Pre-possession Activities) and such access shall not be deemed to trigger the Commencement Date. Prepossession Activities shall not include storage of (and Tenant shall not store) any materials or
furniture in the Demised Premises prior to the Commencement Date. Doing so shall trigger the Commencement Date.

(B) In
connection with all Pre-possession Activities (and as a condition to Owners permitting the same):

(1) Tenant shall
comply with all applicable provisions of this lease governing alterations prior to requesting access to the Demised Premises therefor and shall comply with all applicable Building-standard reasonable rules and regulations of Owner in connection with
such activities;

(2) Tenant shall not interfere in any respect with the performance of Owners Initial Work (as defined
in Section 50(a) below), it being agreed that, subject to Section 37(a)(ii)(A) above, Owner and Tenant shall coordinate the conduct of the Prepossession Activities so as to minimize such interference;

(3) Any delay suffered by Owner in the performance of Owners Initial Work by reason of such work by Tenant shall constitute a
Tenants Delay (as defined in Section 50(c) below) for purposes of this lease;

(4) Tenant shall make its initial
request for access in connection with each Pre-possession Activity constituting a distinct activity (or project) upon not less than three (3) Business Days prior written notice, except for the taking of measurements and performing inspections,
which request shall be made on reasonable advance notice (which may be made orally); and

(5) Owner shall have no obligation
to provide for the protection or safekeeping of any materials or equipment left or installed in the Demised Premises in connection with any Pre-possession Activities and Owner shall have no liability for damage or theft thereof, except to the extent
arising out of Owners willful misconduct.

(b) The rental rate per period payable hereunder (sometimes referred to
herein as the rent, Rent, or Fixed Rent) shall be as set forth in Schedule A annexed hereto and made a part hereof. Fixed Rent shall be payable in lawful money of the United States

lease, the term Additional Charges shall mean all charges, fees and other sums of money (other than Fixed Rent) as shall be due and payable from time to time by Tenant to Owner pursuant to this lease.

(c) Notwithstanding anything to the contrary contained in this lease, provided that Tenant shall not then be in default
under any of the terms, covenants and conditions contained in this lease beyond the expiration of any applicable notice and/or cure period, Tenant shall be entitled to an abatement of the Fixed Rent payable for the period (the Abatement
Period) from the Commencement Date to, but not including, the ninety-first (91st) day after the Commencement Date (such 91stday, the Rent Commencement Date); provided, however, that during the Abatement Period, Tenant shall not be relieved of its obligation to pay the portion of Fixed Rent
applicable to electricity charges pursuant to Article 42 below with respect to such Abatement Period, plus any Additional Charges with respect to the Abatement Period. Notwithstanding the foregoing, if this lease shall terminate (or Owner shall
re-enter the Demised Premises) during the first year of the term of this lease due to Tenants default hereunder, Tenant shall immediately repay to Owner the unamortized portion of the amounts abated during the Abatement Period (which
amortization shall be calculated on a monthly, straight-line basis, over the term of this lease).

(d) Promptly after the
occurrence of the Commencement Date, Owner and Tenant shall, at Owners option, confirm the Commencement Date, the Rent Commencement Date, the First Rent Adjustment Date (as defined in Schedule A below) and the Expiration Date by
executing an instrument reasonably satisfactory to Owner and Tenant; provided, that, the failure by Owner or Tenant to execute such an instrument shall not affect the determination of such dates pursuant to the provisions of this
lease.

(e) (i) Notwithstanding anything to the contrary contained herein, if the Commencement Date shall not have occurred on
or before May 1, 2010 (the Delivery Outside Date), such date to be extended by one day for each day of Tenants Delay and/or Force Majeure Delay (as hereinafter defined), then, provided that Tenant shall not be in
default under this lease, as Tenants sole and exclusive remedy therefor, the Abatement Period shall be extended by one (1) day for each day beyond the Delivery Outside Date that the Commencement Date shall not have occurred.

(ii) Notwithstanding anything to the contrary contained in this lease, if the Commencement Date shall not have
occurred on or before June 1, 2010 (as the same may be extended by one day for each day of Tenants Delay and/or Force Majeure Delay, the Delivery Termination Date), then Tenant shall have the option, as its sole and
exclusive remedy, to terminate this lease by written notice (the Cancellation Notice) given to Owner within twenty (20) days after the Delivery Termination Date and this lease shall thereafter be cancelled and of no further
force and effect on the twentieth (20th) day
following Owners receipt of Tenants Cancellation Notice (the Cancellation Date); provided, however, that notwithstanding Tenants delivery of a Cancellation Notice, this lease shall not be canceled
if the Commencement Date occurs on or before the Cancellation Date. If Tenant fails to timely deliver a Cancellation Notice to Owner within twenty (20) days after the Delivery Termination Date, Tenant shall be deemed to have irrevocably waived
its right to cancel this lease pursuant to this Section 37(e). If this lease shall be canceled as aforesaid, this lease shall be deemed to be null and void and Owner shall promptly return to Tenant all prepaid rent and the Security Deposit.

(iii) As used, herein, the term Force Majeure Delay means delay due to strikes, lockouts or other labor
or industrial troubles, governmental pre-emption in connection with a national emergency, conditions of supply or demand that are affected by war or other national, state or municipal emergency, fire or other casualty, acts of God, any rule, order
or regulation or other action of any governmental agency applicable to all or any part of the Building or the, Demised Premises, unless arising out of a partys knowing non-compliance therewith, or any other cause beyond a partys
reasonable control, whether or not similar to any of the causes hereinabove stated, other than any cause arising by a the negligence or willful misconduct of the party claiming the delay.

or imposed with respect to the rentals payable hereunder other than general income, gross receipts and excess profits taxes (except that general income, gross receipts and excess profits taxes shall be included if covered by the provisions of the
following sentence). Taxes shall also include any taxes, charges or assessments levied, assessed or imposed by any taxing authority in addition to or in lieu of the present method of real estate taxation, provided such additional or substitute

shall be taken into account in determining the amount of Taxes for the applicable Tax Year. With respect to any Tax Year, all expenses, including legal fees, experts and other witnesses fees, incurred in contesting the validity or amount
of any Taxes or in obtaining a refund of Taxes, shall be considered as part of the Taxes for such Tax Year. Notwithstanding the foregoing, Taxes shall not include franchise taxes, gift taxes, capital stock taxes, inheritance taxes or estate taxes.
Tenant hereby waives any right to institute or join in tax certiorari proceedings or other similar proceedings contesting the amount or validity of any Taxes.

(b) If the Taxes payable for any Tax Year shall exceed the Base Taxes, Tenant shall pay to Owner, as Additional Charges for. such Tax Year, an amount (herein called the Tax Payment) equal to Tenants Percentage of
the amount by which the Taxes payable by Owner for such Tax Year are greater than the Base Taxes.

(c) The Tax Payment for
each Tax Year shall be due and payable in installments in the same manner that Taxes for such Tax Year are due and payable to the City of New York, except that Tenant shall pay Tenants Percentage of each such installment to Owner at least
thirty (30) days prior to the date such installment first becomes due to the City of New York. Owners failure to render a Tax Statement with respect to any Tax Year shall not prejudice Owners right thereafter to render a Tax
Statement with respect to any such Tax Year nor shall the rendering of a Tax Statement prejudice Owners right thereafter to render a corrected Tax Statement for that Tax Year.

(d) In the event Taxes for any Tax Year or part thereof shall be reduced after Tenant shall have paid Tenants Tax Payment in respect
of such Tax Year, Owner shall set forth in the first Tax Statement thereafter submitted to Tenant the amount of such refund and, provided that Tenant is not then in default under this lease, Tenant shall receive a credit against the installment or
installments of Tenants Tax Payment next falling due equal to Tenants Percentage of such refund, but in no event shall the credit exceed the amount of the Additional

---

Charges paid by Tenant with respect to Taxes for said Tax Year. If the Taxes comprising the Base Taxes are reduced as a result of an appropriate proceeding or otherwise, the Taxes as so reduced
shall for all purposes be deemed to be Taxes for the Base Taxes, and Owner shall give notice to Tenant of the amount by which the Tax Payments previously made were less than the Tax Payments required to be made under this Article 38, and Tenant
shall pay the amount of the deficiency within ten (10) days after demand therefor.

(e) The expiration or termination of
this lease during any Tax Year for any part or all of which there is a Tax Payment or refund due under this Article 38 shall not affect the rights or obligations of the parties hereto respecting such Tax Payment or refund and any Tax Statement
relating to such Tax Payment may, on a pro-rata basis, be sent to Tenant subsequent to, and all such rights and obligations shall survive, any such expiration or termination. Any such payment shall be (i) calculated based on a year of 365 days
and paid based on the actual number of days elapsed and (ii) shall be payable within thirty (30) days after such statement is sent to Tenant.

39. ATTORNMENT AND NOTICE TO OWNER.

Supplementing the provisions of
Article 7 of this lease:

(a) This lease, and all rights of Tenant hereunder, are and shall be subject and subordinate to all
ground leases, overriding leases and underlying leases of the Land and/or the Building and/or that portion of the Building of which the Demised Premises are a part, now or hereafter existing and to all mortgages and assignments of leases and rents
(each such mortgage or assignment is hereinafter referred to as a mortgage) which may now or hereafter affect the Land and/or the Building and/or that portion of the Building of which the Demised Premises are a part and/or any of
such leases, whether or not such mortgages shall also cover other lands and/or buildings and/or leases, to each and every advance made or hereafter to be made under such mortgages, and to all renewals, modifications, replacements and extensions of
such leases and such mortgages and spreaders and consolidations of such mortgages. This Section shall be self-operative and no further instrument of subordination shall be required. In confirmation of such subordination, Tenant shall promptly
execute, acknowledge and deliver any instrument that Owner, the lessor under any such lease or the holder of any such mortgage or any of their respective successors-in-interest may reasonably request to evidence such subordination; and if Tenant
fails to execute, acknowledge or deliver any such instruments within ten (10) business days after Owners written request therefor, Tenant hereby irrevocably constitutes and appoints Owner as Tenants attorney-in-fact, coupled with an
interest, to execute and deliver any such instruments for and on behalf of Tenant. Any lease to which this lease is, at the time referred to, subject and subordinate is herein called Superior Lease and the lessor of a Superior
Lease or its successor in interest, at the time referred to, is herein called Superior Lessor; and any mortgage to which this lease is, at the time referred to, subject and subordinate is herein called Superior
Mortgage and the holder of a Superior Mortgage is herein called Superior Mortgagee.

(b) 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, Tenant shall not
exercise such right until (i) it has given written notice of such act or omission to Owner and each Superior Mortgagee and each Superior Lessor whose name and address shall previously have been furnished to Tenant and (ii) a reasonable
period for remedying such act or omission shall have elapsed following the giving of such notice (which reasonable period shall be the period to which Owner would be entitled under this lease or otherwise, after similar notice, to effect such remedy
plus thirty (30) days). As of the date of this lease, (i) the holder of the only Superior Mortgage encumbering the Land and Building is LaSalle Bank National Association, as Trustee for the benefit of the Holders of Morgan Stanley Capital
I, Inc. Commercial Mortgage Pass-Through Certificates Series 2005-IQ9, its Successors and/or Assigns, c/o Principal Global Investors, LLC, 801 Grand Avenue, Des Moines, Iowa 50392-1450 and (ii) there is no Superior Lessor.

(c) If any Superior Lessor or Superior Mortgagee, or any designee of any Superior Lessor or Superior Mortgagee, shall succeed to the rights
of Owner under this lease, whether through possession or foreclosure action or delivery of a new lease or deed, then at the request of such party so succeeding to Owners rights (herein called Successor Owner), Tenant



- 4 -



---

shall attorn to and recognize such Successor Owner as Tenants Owner under this lease and shall promptly execute and deliver any instrument that such Successor Owner may reasonably request
to evidence such attornment. Upon such attornment this lease shall continue in full force and effect as a direct lease between the Successor Owner and Tenant upon all of the terms, conditions and covenants as are set forth in this lease, except that
the Successor Owner shall not be:

(i) liable for any previous act or omission of Owner (or its predecessors in interest);

(ii) responsible for any moneys owing by Owner to the credit of Tenant;

(iii) subject to any credits, offsets, claims, counterclaims, demands or defenses which Tenant may have against Owner (or its predecessors
in interest);

(iv) bound by any payments of rent which Tenant might have made for more than one (1) month in advance to
Owner (or its predecessors in interest);

(v) bound by any covenant to undertake or complete any construction of the Demised
Premises or any portion thereof;

(vi) required to account for any security deposit other than any security deposit actually
delivered to the Successor Owner;

(vii) bound by any obligation to make any payment to Tenant or grant or be subject to any
credits, except for services, repairs, maintenance and restoration provided for under this lease to be performed after the date of attornment and which Owners of like properties ordinarily perform at the owners expense, it being expressly
understood, however, that the Successor Owner shall not be bound by an obligation to make payment to Tenant with respect to construction performed by or on behalf of Tenant at the Demised Premises;

(viii) bound by any modification of this lease made without the written consent of the Superior Mortgagee or Superior Lessor, as the case
may be; or

(ix) required to remove any person occupying the Demised Premises or any part thereof.

(d) If a Superior Mortgagee or prospective superior mortgagee shall request modifications to this lease, Tenant shall not unreasonably
withhold, delay or defer Tenants consent thereto, provided that such modifications shall not increase Tenants monetary obligations hereunder or increase tenants non-monetary obligations hereunder by more than a de minimis amount or
adversely affect the leasehold interest hereby created by more than a de minimis amount. In no event shall a requirement that the consent of any such Superior Mortgagee or prospective superior mortgagee be given for any modification of this lease or
for any assignment or sublease, be deemed to materially adversely affect the leasehold interest hereby created.

40.

(a) (i) Tenant shall not, whether voluntarily, involuntarily, or by operation of law or
otherwise (A) assign or otherwise transfer this lease or the term and estate hereby granted, or offer or advertise to do so, (B) sublet the Demised Premises or offer or advertise to do so, or allow the same to be used, occupied or utilized
by anyone other than Tenant, (C) mortgage, pledge, encumber or otherwise hypothecate this lease or the Demised Premises or any part thereof in a manner whatsoever or (D). permit the Demised Premises or part thereof to be occupied, or used for

(ii) Tenant expressly covenants and agrees that (A) if Tenant is a corporation, a
transfer of more than fifty percent (50%) at any one time or, in the aggregate from time to time of the shares of any class of the issued and outstanding stock of Tenant, its successors or assigns, or the issuance of additional shares of any
class of its stock to the extent of more than 50% of the number of shares of said class of stock issued and outstanding at the time that it became the tenant hereunder or (B) if Tenant is a partnership, limited liability company, unincorporated
association or other entity, the sale or transfer of more than 50% of the partnership, membership, joint venture, unincorporated association interests or other form of beneficial interests of Tenant, its successors or assigns, shall constitute an
assignment of this lease and, unless in each instance the prior written consent of Owner has been obtained, shall constitute a default under this lease and shall entitle Owner to exercise all rights and remedies provided for herein in the case of
default. Notwithstanding the foregoing provisions of this Section 40(a)(ii), transfers of stock in a corporation whose shares are traded in the over-the-counter market or any recognized national securities exchange shall not
constitute an assignment for purposes of this lease, provided that the principal purpose of such transfer or transfers is not to avoid the restrictions on assignment otherwise applicable under this Article 40.

(b) (i) If Tenant is a corporation, limited liability company, partnership or similar entity, Owners consent shall not be
required with respect to sublettings to any corporation or similar entity or to any limited liability company, partnership or similar entity which is an Affiliate of Tenant, provided that (1) any such Affiliate is a reputable entity of good
character and (2) a duplicate original instrument of sublease in form and substance reasonably satisfactory to Owner, duly executed by Tenant and such Affiliate, shall have been delivered to Owner at least ten (10) days prior to the
effective date of any such sublease. For purposes of this Article 40, the term Affiliate shall mean any entity which controls or is controlled by or under common control with tenant, and the term control shall mean, in the
case of a corporation, ownership or voting control, directly or indirectly, of at least fifty (50%) percent of all the voting stock, and in case of a joint venture, limited liability company, partnership or similar entity, ownership, directly
or indirectly, of at least fifty (50%) percent of all the general or other partnership, membership (or similar) interests therein.

(ii) If Tenant is a corporation, limited liability company, partnership or similar entity, Owners consent shall not be required with respect to an assignment of this lease to an Affiliate of Tenant,
provided that (1) the assignee is a reputable entity of good character, (2) a duplicate original instrument of assignment in form and substance reasonably satisfactory to Owner, duly executed by Tenant, shall have been delivered to Owner
at least ten (10) days prior to the effective date of any such assignment, (3) an instrument in form and substance satisfactory to Owner, duly executed by the assignee, in which such assignee assumes (as of the Commencement Date)
observance and performance of, and agrees to be personally bound by, all of the terms, covenants and conditions of this lease on Tenants part to be performed and observed shall have been delivered to Owner not more than ten (10) days
after the effective date of such assignment, (4) such assignment is for a legitimate business purpose and not principally for the purpose of avoiding the restrictions on assignment otherwise applicable under this Article 40 and (5) such
assignee has a net worth computed in accordance with generally accepted accounting principles at least equal to the greater of (A) the net worth of Tenant on the date of this Lease (B) the net worth of Tenant immediately prior to such
assignment and (C) $2,000,000.00.

(iii) If Tenant is a corporation, limited liability company, partnership or similar
entity, Owners consent shall not be required with respect to an assignment of this lease to a corporation, limited liability company, partnership or similar entity into or with which Tenant is merged or consolidated or transactions with a
corporation, limited liability company, partnership or similar entity to which all or substantially all of Tenants assets are sold, provided that (1) the successor to Tenant is a reputable entity of good character, (2) a duplicate
original instrument of assignment in form and substance reasonably satisfactory to Owner, duly executed by Tenant and such Affiliate, shall have been delivered to Owner at least ten (10) days prior to the effective date of any such assignment;,
(3) an instrument in form and substance reasonably satisfactory to Owner, duly executed by the assignee, in which such assignee assumes (as of the Commencement Date) observance and performance of, and agrees to be bound by, all of the terms,
covenants and conditions of this lease on Tenants part to be performed and observed shall have been delivered to Owner not more than ten (10) days after the effective date of such



- 6 -



---

assignment, (4) such assignment is for a legitimate business purpose and not principally for the purpose of avoiding the restrictions on assignment otherwise applicable under this Article 40
and (5) such assignee has a net worth computed in accordance with generally accepted accounting principles at least equal to the greater of (A) the net worth of Tenant on the date of this lease, (B) the net worth of Tenant immediately
prior to such assignment and (C) $2,000,000.00.

(c) If this lease be assigned, whether or not in violation of the
provisions of this lease, Owner may collect rent from the assignee. If the Demised Premises are sublet or used or occupied by anybody other than Tenant, whether or not in violation of this lease, Owner may collect rent from the subtenant or
occupant. In either event, Owner may apply the net amount collected to the Fixed Rent and Additional Charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of any of the provisions of
Section 40(a), or the acceptance of the assignee, subtenant or occupant as tenant, or a release of Tenant from the performance by Tenant of Tenants obligations under this lease. The consent by Owner to a particular assignment, mortgaging,
subletting or use or occupancy by others shall not in any way be considered a consent by Owner to any other or further assignment, mortgaging or subletting or use or occupancy by others not expressly permitted by this Article 40. References in this
lease to use or occupancy by others (that is, anyone other than Tenant) shall not be construed as limited to subtenants and those claiming under or through subtenants but shall also include licensees and others claiming under or through Tenant,
immediately or remotely.

(d) Any assignment or transfer, whether made with or without Owners consent, shall be made
only if, and shall not be effective until, the assignee shall execute, acknowledge and deliver to Owner an agreement in form and substance reasonably satisfactory to Owner whereby the assignee shall assume the obligations of this lease on the part
of Tenant to be performed or observed and whereby the assignee shall agree that the provisions in Section 40(a) shall, notwithstanding such assignment or transfer, continue to be binding upon it in respect of all future assignments and
transfers. The original named Tenant covenants that, notwithstanding any assignment or transfer, whether or not in violation of the provisions of this lease, and notwithstanding the acceptance of Fixed Rent and/or Additional Charges by Owner from an
assignee, transferee, or any other party, the original named Tenant shall remain fully liable for the payment of the Fixed Rent and Additional Charges and for the other obligations of this lease on the part of Tenant to be performed or observed.

(e) The joint and several liability of Tenant and any immediate or remote successor in interest of Tenant and the due
performance of the obligations of this lease on Tenants part to be performed or observed shall not be discharged, released or impaired in any respect by any agreement or stipulation made by Owner extending the time of, or modifying any of the
obligations of, this lease, or by any waiver or failure of Owner to enforce any of the obligations of this lease.

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

(g) Notwithstanding anything to the contrary contained in this Article 40, if Tenant shall at any time or times during the term of this lease desire to assign this lease or sublet all or any portion of
the Demised Premises, Tenant shall give notice thereof to Owner (the Assignment/Sublet Request), which Assignment/Sublet Request shall be accompanied by (i) a conformed or photostatic copy of the proposed assignment or
sublease, the effective or commencement date of which shall be at least forty-five (45) days after the giving of such Assignment/Sublet Request, (ii) a statement setting forth in reasonable detail the identity of the proposed assignee or
subtenant, the nature of its business and its proposed use of the Demised Premises, and (iii) current financial information with respect to the proposed assignee or subtenant, including, without limitation, its most recent certified financial
statements, if such financial statements are certified (or, if not, certified by the chief financial officer of the proposed assignee or subtenant as being true and correct). The Assignment/Sublet Request shall be deemed an offer from Tenant to
Owner whereby Owner (or Owners designee) may, at its option, (A) terminate this lease (if the proposed transaction is an assignment or a sublease of all



- 7 -



---

or substantially all of the Demised Premises) or (B) terminate this lease with respect to the space covered by the proposed sublease (if the proposed transaction is a sublease of less than
all or substantially all of the Demised Premises). Said option may be exercised by Owner by notice to Tenant at any time within forty-five (45) days after the Assignment/Sublet Request has been given by Tenant to Owner; and during such 45-day
period Tenant shall not assign this lease or sublet the Demised Premises to any person or entity.

(h) If Owner exercises its
option to terminate this lease in the case where Tenant desires either to assign this lease or sublet all or substantially all of the Demised Premises, then this lease shall end and expire on the date that such assignment or sublet was to be
effective or commence, as the case may be, and the Fixed Rent and Additional Charges shall be paid and apportioned to such date.

(i) If Owner exercises its option to terminate this lease with respect to the space covered by Tenants proposed sublease in any case where Tenant desires to sublet part of the Demised Premises, then (i) this lease shall end and
expire with respect to such part of the Demised Premises on the date that the proposed sublease was to commence; (ii) from and after such date the Fixed Rent and Additional Charges shall be adjusted, based upon the proportion that the rentable area
of the Demised Premises remaining bears to the total rentable area of the Demised Premises; and (iii) Tenant shall pay to Owner, upon demand, as Additional Charges hereunder the costs incurred by Owner in physically separating such part of the
Demised Premises from the balance of the Demised Premises and in complying with any laws and requirements of any public authorities relating to such separation.

(j) In the event Tenant shall have complied with the provisions of Section 40(g) and Owner does not exercise its options pursuant to Section 40 (g) to terminate this lease in whole or in
part, and provided that Tenant is not in default of any of Tenants obligations under this lease beyond the expiration of any applicable notice and/or cure period, either at the time Owners consent to such assignment or sublease is
requested or at the commencement of the term of any proposed sublease or on the effective date of any such assignment, Owners consent (which must be in writing and in form satisfactory to Owner) to the proposed assignment or sublease shall not
be unreasonably withheld, provided and upon condition that:

(i) In Owners judgment the proposed assignee or subtenant
is engaged in a business and the Demised Premises will be used in a manner which is limited to the use expressly permitted under Article 2;

(ii) The proposed assignee or subtenant is a reputable person of good character whose tenancy shall comport with the first class character of the Building, having a net worth satisfactory to Owner
considering the responsibility involved;

(iii) Neither (A) the proposed assignee or sublessee nor (B) any person
which, directly or indirectly, controls, is controlled by, or is. under common control with, the proposed assignee or sublessee or any person who controls the proposed assignee or sublessee, is (x) then an occupant of any part of the Building
or any other building owned or operated under a ground or underlying lease by Owner or any person which, directly or indirectly, controls, is controlled by, or is under common control with Owner or any person who controls Owner or (y) a person
with whom Owner is then (or within the immediately preceding six-month period was) negotiating to lease space in the Building;

(iv) The form of the proposed sublease shall be in form reasonably satisfactory to Owner and shall comply with the applicable provisions of this Article 40 (including, without limitation Section 40(1) below);

(v) There shall not be more than one (1) occupant of the Demised Premises (i.e., either Tenant or Tenants subtenant);

(vi) Tenant shall reimburse Owner on demand for the reasonable costs that may be incurred by Owner in connection with said
assignment or sublease, including, without limitation, the costs of making investigations as to the acceptability of the proposed



- 8 -



---

assignee or subtenant, and legal costs incurred in connection with the granting of any requested consent;

(vii) No advertisement shall have stated the proposed rental, and Tenant shall not have listed the Demised Premises for subletting, whether through a broker, agent, representative, any computerized or
electronic listing system or service (including, without limitation Co-Star or Re-locate) or otherwise, at a rental rate less than the fixed rent and additional charges at which Owner is then offering to lease other space in
the Building. Nothing contained in this subclause (vii) shall be construed to prohibit Tenant from actually entering into a sublease at a rental less than the amount described in the preceding sentence.

(k) If Owner fails to exercise any of its options under Section 40(g) and

(i) (x) Owner consents to a proposed assignment or sublease and (y) Tenant fails to execute and deliver to Owner an assignment or
sublease within sixty (60) days after the giving of such consent; or

(ii) if the form of sublease or assignment
executed and delivered by Tenant shall not be on the same material terms set forth in the form sublease or assignment, as the case may be, delivered to Owner together with the Assignment/ Sublet Request,

then in either of such events, Tenant shall again comply with all of the provisions and conditions of Section 40(g) before assigning this lease or
subletting all or part of the Demised Premises.

(l) With respect to each and every sublease or subletting authorized by Owner
under the provisions of this lease, it is further agreed:

(i) No subletting shall be for a term ending later than one day
prior to the expiration date of this lease.

(ii) No sublease shall be valid, and no subtenant shall take possession of the
Demised Premises until an executed counterpart of such sublease has been delivered to Owner.

(iii) Each sublease shall
provide that it is subject and subordinate to this lease and to the matters to which this lease is or shall be subordinate, and that in the event of termination, re-entry or dispossess by Owner under this lease Owner may, at its option, take over
all of the right, title and interest of Tenant, as sublessor, under such sublease, and such subtenant shall, at Owners option, attorn to Owner pursuant to the then executory provisions of such sublease, except that Owner shall not (A) be
liable for any previous act or omission of Tenant under such sublease, (B) be subject to any offset, not expressly provided in such sublease, which theretofore accrued to such subtenant against Tenant, or (C) be bound by any previous
modification of such sublease or by any previous prepayment of more than one months rent.

(iv) Each sublease shall
(A) provide that the subtenant may not assign its rights thereunder or further sublet the space demised under the sublease, in whole or in part, without Owners consent, which consent shall not be unreasonably withheld or delayed, but such
right to sublet or assign shall be subject to all other provisions of this Article 40, including, without limitation, Owners rights under Section 40(g) and (B) set forth the terms and provisions of Section 40(b), with the
subtenant being subject to the restrictions in Section 40(b) applicable to Tenant.

(v) No sublease shall demise less
than the entire Demised Premises.

(m) If the Owner shall give its consent to any assignment of this lease or to any sublease,
Tenant shall in consideration therefor, pay to Owner, as Additional Charges, an amount equal to seventy-five percent (75%) of the Assignment Profit (hereinafter defined) or Sublease Profit (hereinafter defined), as the case may be.

(i) The term Assignment Profit as used herein shall mean an amount equal to the excess of (x) all sums and other
consideration paid to Tenant by the assignee for or



- 9 -



---

by reason of such assignment, including, without limitation, any sums paid for Tenants fixtures, leasehold improvements, equipment, furniture, furnishings or other personal property over
(y) the Transaction Costs (as hereinafter defined).

(ii) The term Sublease Profit as used herein
shall mean an amount equal to the excess of (x) any rents, additional charges or other consideration payable under the sublease to Tenant by the subtenant (including, without limitation, any fee, penalty or charge paid by the subtenant for the
right to cancel the sublease) which is in excess of the Fixed Rent and Additional Charges accruing during the term of the sublease in respect of the subleased space (at the rate per square foot payable by Tenant hereunder) pursuant to the terms
hereof, including, without limitation, any sums paid for the value of Tenants fixtures, leasehold improvements, equipment, furniture, furnishings or other personal property over (y) the Transaction Costs.

(iii) The term Transaction Costs shall mean, with respect to any assignment or subletting, the following costs incurred
by Tenant: the cost of work performed to prepare the Demised Premises for the assignee or subtenant, the sum of customary brokerage commissions incurred in connection with the assignment or sublease, and reasonable attorneys fees incurred in
connection with the preparation and negotiation of the assignment or sublease (but not including attorneys fees incurred in connection with obtaining Owners consent to the assignment or sublease). In calculating Assignment Profit or
Sublease Profit, all Transaction Costs shall be amortized on a straight-line basis over the term of the sublease (or over the balance of the term of this lease in the case of an assignment).

(n) The sums payable under Section 40(m) above shall be paid to Owner as and when paid by the assignee or the subtenant, as the case
may be, to Tenant. Tenant shall use all reasonable efforts to collect (1) in the case of an assignment, all sums and other consideration payable to it by the assignee for or by reason of such assignment and (2) in the case of a sublease,
all rents, additional charges and other consideration payable to it under the sublease and, in every case, Tenant shall, from time to time upon written demand by Owner, provide Owner with an accounting of all such sums payable to it by any such
assignee and/or subtenant.

(o) Each subletting shall be subject to all of the covenants, agreements, terms, provisions and
conditions contained in this lease. Notwithstanding any subletting and/or acceptance of rent or additional charges by Owner from any subtenant, Tenant shall and will remain fully liable for the payment of the Fixed Rent and Additional Charges 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 and all acts and omissions of any licensee or subtenant or anyone
claiming under or through any subtenant which shall be in violation of any of the obligations of this lease, and any such violation shall be deemed to be a violation by Tenant. Tenant further agrees that notwithstanding any such subletting, no other
and further subletting of the Demised Premises by Tenant or any person claiming through or under Tenant shall or will be made except upon compliance with and subject to the provisions of this Article 40. If Owner shall decline to give its consent to
any proposed assignment or sublease, or if Owner shall exercise any of its options under Section 40(g), Tenant shall indemnify, defend and hold harmless Owner against and from any and all loss, liability, damages, costs and expenses (including
reasonable counsel fees) resulting from any claims that may be made against Owner by the proposed assignee or subtenant or by any brokers or other persons claiming a commission or similar compensation in connection with the proposed assignment or
sublease.

(p) Tenant shall reimburse Owner on demand for any reasonable costs that may be incurred by Owner in connection
with any proposed assignment or sublease, whether or not consummated, including, without limitation, the reasonable costs of making investigations as to the acceptability of the proposed assignee or subtenant, and reasonable legal costs incurred in

(a) Subject to the provisions of this Article 42, Owner shall furnish the electric energy that Tenant shall reasonably require in the Demised Premises for the purposes permitted under this lease on a
rent inclusion basis and there shall be no separate charge to Tenant for such electric energy, such electric energy being included in Owners services which



- 11 -



---

are covered by the Fixed Rent. Owner and Tenant agree that the Base Electric Charge (hereinafter defined) represents the amount initially included in the annual Fixed Rent set forth in
Section 37(b) hereof to cover the furnishing of such electric energy by Owner on a rent inclusion basis and that such Base Electric Charge component of Fixed Rent shall in no event be subject to reduction, but shall be subject to being
increased as hereinafter provided. Owner shall not be liable in any event to Tenant for any failure, interruption or defect in the supply or character of electric energy furnished to the Demised Premises by reason of any requirement, act or omission
of the public utility serving the Building with electricity or for any other reason not attributable solely to Owners willful misconduct or gross negligence (but in no event shall Owner be responsible for any consequential damages). For
purposes of this Article 42, the Base Electric Charge shall mean an annual amount equal to Nine Thousand Nine Hundred Forty-Seven and 00/100 Dollars ($9,947.00).

(b) Owner will furnish electric energy to Tenant through currently installed electric facilities for Tenants reasonable use of such
lighting and other electrical fixtures, appliances and equipment required for the conduct of Tenants business in the Demised Premises. At any time, and from time to time, after Tenant shall have entered into possession of the Demised Premises,
or any portion thereof, Owner may designate an independent electrical consultant to make a survey or resurvey of the electrical consumption and power load on the Demised Premises to determine Tenants average electrical consumption and demand
taking into account, such usage factors as Owner may reasonably determine. If the cost of Tenants average electrical consumption is greater than the estimated consumption upon which the electric rent inclusion plan was initially
based (or greater than the Base Electric Charge (as such charge and the fixed rent may have previously been increased pursuant to a previous survey and/or Section 42(c) below) the Fixed Rent hereunder shall, upon written notice from Owner to
Tenant, be increased by the incremental annual cost of Tenants consumption and demand, as estimated by the electrical consultant, effective as of the date the increase in such electric consumption occurred (as determined by the electrical
consultant) or, with respect to the initial survey, as of the Commencement Date. The initial unpaid amount of each such adjustment shall be paid within ten (10) days after Owner furnishes Tenant with a statement thereof. Thereafter, the Fixed
Rent shall be increased appropriately. In no event shall the rent-inclusion component Of Fixed Rent hereunder ever be less than the Base Electric Charge.

(c) If at any time during the term of this lease the Electric Rate (as hereinafter defined) shall be changed so as to exceed the Electric Rate then in effect on the date of this lease (as same may have
been increased pursuant to the provisions of this Article), then, effective as of the date of each such change in the Electric Rate, the charge for electricity included in the Fixed Rent shall be increased or decreased in proportion to such change
in the Electric Rate (as determined by Owners electrical consultant but in no event, however, shall such electric consumption charge be reduced below the Electric Rate then in effect). The term Electric Rate shall mean at
the time in question 110% of the public utility (and/or third party supplier) rate schedule (including all surcharges, taxes, fuel adjustments, taxes regularly passed on to consumers by the public utility, and other sums payable in respect thereof)
for the supply of electric energy to Owner for the Building. Notwithstanding the foregoing provisions of this Section, if the public utility rate schedule (with such inclusions) applicable to Owner for the purchase of electric energy for the
Building shall be less than the public utility rate schedule applicable to Owner if Owner were to purchase electricity solely for the Demised Premises, then the higher rate schedule shall be used in determining the Electric Rate.

(d) Tenants use of electric energy in the Demised Premises shall not at any time exceed the capacity of any of the electrical
conductors and equipment in or otherwise serving the Demised Premises.

(e) Owner reserves the right to discontinue furnishing
electric energy to Tenant in the Demised Premises at any time upon not less than 30 days 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 termination Owner shall not be obligated to furnish electric energy to Tenant and the Fixed Rent payable under this lease shall be reduced by an amount equal to the rent inclusion component of such Fixed
Rent. If Owner so discontinues furnishing electric energy to Tenant, Tenant shall arrange to obtain electric energy directly from the public utility company furnishing electric energy to the



- 12 -



---

Building. Such electric energy may be furnished to Tenant by means of the then existing Building system feeders, risers and wiring to the extent that the same are available, suitable and safe for
such purpose. All meters and additional panel boards, feeders, risers, wiring and other conductors and equipment which may be required to obtain electric energy directly from such public utility company shall be furnished and installed by Owner at
Tenants expense, but Owner may, at its option, before commencing any such work or at any time thereafter, require Tenant to furnish to Owner such security in form (including, without limitation, a bond issued by a corporate surety licensed to
do business in New York) and amount as Owner shall deem necessary to assure the payment for such work by Tenant.

43.

permissible to permit Owner to collect the maximum rents which from time to time during the continuance of such legal rent restriction may be legally permissible (and not in excess of the amounts reserved therefor under this lease). Upon the
termination of such legal rent restriction, (i) the Fixed Rent and/or Additional Charges shall become and thereafter be payable in accordance with the amounts reserved herein for the periods following such termination, and (ii) Tenant
shall pay to Owner promptly upon being billed, to the maximum extent legally permissible, an amount equal to (x) the Fixed Rent and/or Additional Charges which would have been paid pursuant to this lease but for such legal rent restriction less
(y) the rents paid by Tenant during the period such legal rent restriction was in effect.

Tenant.

(v) This lease shall not be binding on Owner or Tenant unless and until each of Owner and Tenant shall have executed
this lease and Owner shall have delivered a fully executed original counterpart of this lease to Tenant

Notwithstanding the foregoing, communications from Owner, such as correspondence and Rent bills for Fixed Rent and/or Additional Charges, which are sent in
the ordinary course of business need only be sent to Tenant and may be sent exclusively by regular mail.

48. HOLDOVER.

(a) If Tenant shall hold over after the expiration or sooner termination of the term of this lease, then Tenant shall pay on
the first day of each month of the holdover period as Fixed Rent, an amount equal to two (2) times the greater of (i) one-twelfth of the sum of the Fixed Rent and Additional Charges payable by Tenant during the last year of the term of
this lease and (ii) the fair market rental value of the Demised Premises during the holdover period (as determined by Owner). It is stipulated and agreed that Owner shall not be required to perform any work, furnish any materials or make any
repairs within the Demised Premises during the holdover period. It is further stipulated and agreed that if Owner shall, at any time after the expiration or sooner termination of the term, proceed to remove Tenant from the Demised Premises as a
holdover, the Fixed Rent for the use and occupancy of the Demised Premises during any holdover period shall be calculated in the same manner as set forth above. In addition to the foregoing, Owner shall be entitled to recover from Tenant any losses
or damages arising from such holdover. No holding over by Tenant shall operate to extend the term of this lease.

(b) Anything
to the contrary notwithstanding, the acceptance of any rent paid by Tenant pursuant to Section 48(a) above shall not preclude Owner from commencing and prosecuting a holdover or summary eviction proceeding, and the preceding sentence shall be
deemed to be an agreement expressly providing otherwise within the meaning of Section 232-c of the Real Property Law of the State of New York.

(c) If Tenant shall hold-over or remain in possession of any portion of the Demised Premises beyond the Expiration Date, Tenant shall be subject not only to summary proceeding and all damages related
thereto, but also to any damages arising out of any lost opportunities (and/or new leases) by Owner to re-let the Demised Premises (or any part thereof). All damages to Owner by reason of such holding over by Tenant may be the subject of a separate
action and need not be asserted by Owner in any summary proceedings against Tenant.

49. SECURITY DEPOSIT.
Supplementing the provisions of Article 34 hereof:

(a) On the date hereof, Tenant shall be obligated to deliver to Owner
security in the amount of Ninety Thousand Four Hundred Four and 00/100 Dollars ($90,404.00) (the Security Deposit) either in the form of (i) cash or (ii) an unconditional irrevocable letter of credit (an
L/C) in the original principal amount of the Security Deposit.

(b) If Tenant shall elect to deliver the
Security Deposit in the form of an L/C, Tenant shall deliver to Owner an L/C in the amount of the Security Deposit in the form of Exhibit D attached hereto and otherwise in substance reasonably satisfactory to Owner naming Owner as
beneficiary, as security for the faithful performance and observance by Tenant of this lease. The L/C and any renewal L/C shall be drawn on a bank or trust company located in New York City which is a member of the New York Clearing House
Association, or otherwise reasonably satisfactory to Owner. If Tenant defaults in the full and prompt payment and performance of any of Tenants covenants or obligations under this lease beyond any applicable notice and cure period, including,
without limitation, a default in the payment of Fixed Rent or Additional Charges, or a failure to timely provide a renewal L/C to Owner as provided below, Owner may present the L/C for payment and use, apply or retain the whole, or any part of the
proceeds thereof, to the extent required for the payment of any Fixed Rent, Additional Charges or any. other sums owing or which may become due and owing under this lease. If Owner shall so apply, use or retain all or any part of the Security
Deposit, Tenant shall upon demand by



- 20 -



---

Owner, immediately deposit with Owner a sum of cash or an endorsement to the L/C in form and substance reasonably satisfactory to Owner equal to the amount used, applied or retained, as security
as aforesaid, failing which Owner shall have the same rights and remedies as under this lease for non-payment of Fixed Rent. In the event that Tenant shall fully and faithfully comply with the terms, covenants and conditions of this lease, the L/C,
or so much of the proceeds thereof as shall remain after any application pursuant to the terms of this lease, shall be returned to Tenant promptly after the expiration or sooner termination of the term hereof and delivery of possession of the entire
Demised Premises to Owner in the manner required by the terms of this Lease. The L/C shall provide that it is transferable without the banks consent, at no charge to Owner (or, if there is such a charge to transfer the L/C, Tenant shall pay
such charge within five (5) Business Days after demand by Owner, failing which Owner may present the L/C for payment). Tenant agrees to cause the bank to renew said L/C, in the same form (or such other form as may be satisfactory to Owner in
its sole discretion) from time to time during the term of this lease, at least thirty (30) days prior to the expiration of said L/C or any renewal thereof so that an L/C issued by the bank to Owner shall be in force and effect through the term
of this lease. In the event of any sale, transfer or leasing of Owners interest in the Building, Owner shall transfer either the L/C or any sums collected thereunder, together with any other unapplied sums held by Owner as security and the
interest thereon, if any, to which Tenant is entitled, to the vendee, transferee or lessee, and after such transfer and upon giving notice to Tenant of such fact and the name and address of the transferee, Owner shall thereupon be released by Tenant
from all liability for the return or payment thereof, and Tenant shall look solely to the new owner for the return of payment of same.

(c) Owner, in its sole discretion, may apply the Security Deposit against any obligation under this lease in any order it may elect including, without limitation, any Fixed Rent and Additional Charges that accrue after Tenant vacates the
Premises and/or any re-letting charges incurred by Owner as a result of Tenant vacating the Premises prior to the expiration of this lease. Further, Owner may enforce the provisions of any guaranty securing Tenants obligations under this
lease.

50. OWNERS INITIAL WORK.

(a) Owner or its designated contractor(s), in accordance with the provisions of this Article 50, shall perform the work (Owners Initial Work) set forth in the plan attached hereto
as Exhibit E and made a part hereof; provided, however, that Owner shall have the right to make any changes in Owners Initial Work required by any governmental department or bureau having jurisdiction over the Building.
Tenant may not make changes to Owners Initial Work during Owners performance thereof. Owners Initial Work shall be performed by Owner only once, it being understood that Owners obligation to perform Owners Initial Work
is a single, non-recurring obligation. Tenant shall have no right to make any changes to Owners Initial Work.

(b)
(i) For purposes of this lease, the term Substantial Completion Date shall mean the date on which Owners Initial Work is substantially completed or would have been substantially completed but for any Tenants
Delay, (as hereinafter defined) it being understood that substantial completion shall occur notwithstanding the fact that minor details, balancing or adjustments may not then have been completed, provided that such uncompleted work shall not
materially interfere with Tenants use of the Demised Premises. The taking of possession of the demised premises by Tenant shall be deemed a delivery of the demised premises by Owner, substantial completion of Owners Initial Work and an
acceptance by Tenant of the demised premises, subject to the existence of latent defects and the completion of any minor punchlist work. Owner shall proceed diligently to complete any such punchlist work, using commercially reasonable efforts to
complete all punchlist items within thirty (30) days after the Substantial Completion Date.

(ii) Tenant hereby
acknowledges that the Commencement Date hereunder is indeterminate and shall occur only as provided herein and in Article 37 hereof and, except as expressly set forth in Section 37(e) above, Tenant, therefore, waives any right to rescind this
lease under any applicable law, including, without limitation, Section 223(a) of the Real Property law of the State of New York. Except as expressly set forth in Section 37(e)



- 21 -



---

above, Tenant further waives any damages which may result from any delay in the substantial completion of Owners Initial Work (or any portion thereof) or the delivery of possession of the
demised premises on or by any particular date or dates.

(c) The term Tenants Delay shall mean any
delay that Owner may encounter in commencing or performing Owners Initial Work (or any portion thereof) or Owners other obligations pursuant to this Article 50 by reason of any act, neglect, failure or omission by Tenant, its agents,
servants, employees, contractors or subcontractors, or in the performance of Tenants obligations under this Article 50 including, without limitation, Tenants failure to promptly provide information necessary for Owner to substantially
complete Owners Initial Work.

(d) Except for Owners Initial Work, Owner shall have no obligation to pay any money
or perform any other work in, or make any alteration, or improvements to, the Demised Premises or the Building to ready the Demised Premises or the Building for Tenants initial occupancy.
