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. 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 workmans compensation, 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 thereafter, at Tenants expense, by payment or filing the bond required by law. All fixtures and all paneling, partitions, railings and like
installations, installed in the 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 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 any such from the premises or upon removal of other installations as may be required by Owner, Tenant shall immediately and at its expense, repair and restore the premises to the condition existing prior to installation 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 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 premises by Owner, at Tenants expense.



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 the contractor for the trade or trades in question, selected from a list of at least two contractors 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 its 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 premises for which Owner may be responsible hereunder. 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 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 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, 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 premises or the building (including the use permitted under the lease). 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 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 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 judgement, 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 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 (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
therefor nor abatement or diminution of rent 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 sub-tenant, and any agent, contractor, employee, invitee or licensee of any sub-tenant. In case any action or proceeding is brought against Owner by reason of any such claim, Tenant, upon written notice from 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, 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 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 premises shall have been repaired and restored by Owner (or sooner reoccupied in part by 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 90 days after such fire or casualty, or 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 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 premises 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 premises as promptly as reasonably possible, all of Tenants salvageable inventory and moveable equipment,
furniture, and other property. Tenants liability for rent shall resume five (5) days after written notice from Owner that the 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 the foregoing, 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. 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. (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.



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 fixture 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,
distributees, executors, administrators, legal representative, successor 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. Transfer of the majority of the stock of a corporate Tenant or the majority partnership interest of a partnership 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, under-enant 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:



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, 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. Tenant shall permit Owner to use and maintain and replace pipes and conduits in and through the demised premises and to erect new pipes 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 therefor, 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. 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 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
premises and Tenant agrees to accept the same subject to violations, whether or not of record.



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 law of any state naming Tenant as the debtor; or (2) the making by Tenant 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 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 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 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. (1) 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 §235 of Title 11 of the U.S. Code (bankruptcy code); or if Tenant shall fail to move into or take possession of the 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 fifteen (15) days notice upon Tenant specifying the nature of said default and upon the expiration of said 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 fifteen (15) day period, and if Tenant
shall not have diligently commenced curing such default within such 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 demised premises and remove their
effects and hold the 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 proceeding 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 other wise, (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 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 Owner as liquidated damages for the failure of Tenant lo observe and perform said Tenants covenants herein contained, any deficiency between the rent hereby reserved and/or _______ 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 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 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 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 therefor. 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.



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 therefor 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. 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 by 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 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 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 the 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 than the monthly rent herein stipulated shall be deemed to be other than on account of the earliest
stipulated rent, nor shall any endorsement or statement of any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Owner may accept such check or payment without prejudice to Owners right to
recover the balance of such rent or pursue any other remedy in this lease provided. No act or thing done by Owner or Owners agents during the term hereby demised shall be deemed an acceptance of a surrender of said 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 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 said 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 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.



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, a bill, statement, notice or communication which Owner may desire or be required to give to Tenant, shall be deemed sufficiently given or rendered if, in writing, delivered to Tenant
personally or sent by registered or certified mail addressed to Tenant at the building of which the demised premises form a part or at the last known residence address or business address of Tenant or left at any of the aforesaid premises addressed
to Tenant, and the time of the rendition of such bill or statement and of the giving of such notice or communication shall be deemed to be the time when the same is delivered to Tenant, mailed, or left at the premises as herein provided. Any notice
by Tenant to Owner must be served by registered or certified mail addressed to Owner at the address first hereinabove given or at such other address as Owner shall designate by written notice.



Services Provided by Owners:



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 business days from 8 a.m. to 6 p.m.; (c) water for ordinary lavatory purposes, but if Tenant uses or consumes water for any other purposes or in unusual quantities (of which
fact Owner shall be the sole judge), Owner may install a water meter at Tenants expense which Tenant shall thereafter maintain at Tenants expense in good working order and repair to register such water consumption and Tenant shall pay
for water consumed as shown on said meter as additional rent as and when bills are rendered; (d) If the demised premises are serviced by Owners air conditioning/cooling and ventilating system, air conditioning/ cooling will be furnished to
tenant from May 15th through September 30th on business days (Mondays through Fridays, holidays excepted) from 8:00 a.m. to 6:00 p.m., and ventilation will be furnished on business days during the aforesaid hours except when air conditioning/cooling
is being furnished as aforesaid. If Tenant requires air conditioning/cooling or ventilation for more extended hours or on Saturdays, Sundays or on holidays, as defined under Owners contract with Operating Engineers Local 94-94A, Owner will
furnish the same at Tenants expense. RIDER to be added in respect to rates and conditions for such additional service; (e) Owner reserves the right to stop services of the heating, elevators, plumbing, air-conditioning, electric, power systems
or other services, if any, when necessary by reason of accident or for repairs, alterations, replacements or improvements necessary or desirable in the judgment of Owner for as long as may be reasonably required by reason thereof. If the building of
which the demised premises are a part supplies manually operated elevator service, Owner at any time may substitute automatic control elevator service and proceed diligently with alterations necessary therefor without in any way affecting this lease
or the obligation of Tenant hereunder.



Captions:



30. The Captions are inserted only as a matter of convenience and for
reference and in no way define, limit or describe the scope of this lease nor the intent of any provisions thereof.



Definitions:



31. The term office, or offices, wherever used in this lease, shall not be construed to mean premises used as a store or
stores, for the sale or display, at any time, of goods, wares or merchandise, of any kind, or as a restaurant, shop, booth, bootblack or other stand, barber shop, or for other similar purposes or for manufacturing. The term Owner means a
landlord or lessor, and as used in this lease means only the owner, or the mortgagee in possession, for the time being of the land and building (or the owner of a lease of the building or of the land and building) of which the demised premises form
a part, so that in the event of any sale or sales of said land and building or of said lease, or in the event of a lease of said building, or of the land and building, the said Owner shall be and hereby is entirely freed and relieved of all
covenants and obligations of Owner hereunder, and it shall be deemed and construed without further agreement between the parties or their successors in interest, or between the parties and the purchaser, at any such sale, or the said lessee of the
building, or of the land and building, that the purchaser or the lessee of the building has assumed and agreed to carry out any and all covenants and obligations of Owner, hereunder. The words re-enter and re-entry as used in
this lease are not restricted to their technical legal meaning. The term business days as used in this lease shall exclude Saturdays, Sundays and all days as observed by the State or Federal Government as legal holidays and those

agents, visitors, and licensees shall observe faithfully, and comply strictly with, the Rules and Regulations and such other and further reasonable Rules and Regulations as Owner or Owners agents may from time to time adopt. Notice of any
additional rules or regulations shall be given in such manner as Owner may elect. In case Tenant disputes the reasonableness of any additional Rule or Regulation hereafter made or adopted by Owner or Owners agents, the parties hereto agree to
submit the question of the reasonableness of such Rule or Regulation for decision to the New York office of the American Arbitration Association, whose determination shall be final and conclusive upon the parties hereto. The right to dispute the
reasonableness of any additional Rule or Regulation upon Tenants part shall be deemed waived unless the same shall be asserted by service of a notice, in writing upon Owner within fifteen (15) days after the giving of notice thereof. Nothing

in any other lease, as against any other tenant and Owner shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, visitors or licensees.



Security:



34. Tenant has deposited with Owner the sum of $ See Rider as security for the faithful performance and observance by
Tenant of the terms, provisions and conditions of this lease; it is agreed that in the event Tenant defaults in respect of any of the terms, provisions and conditions of this lease, including, but not limited to, the payment of rent and additional
rent, Owner may use, apply or retain the whole or any part of the security so deposited to the extent required for the payment of any rent and additional rent or any other sum as to which Tenant is in default or for any sum which Owner may expend or
may be required to expend by reason of Tenants default in respect of any of the terms, covenants and conditions of this lease, including but not limited to, any damages or deficiency in the re-letting of the premises, whether such damages or
deficiency accrued before or after summary proceedings or other re-entry by Owner. In the event that Tenant shall fully and faithfully comply with all of the terms, provisions, covenants and conditions of this lease, the security shall be returned
to Tenant after the date fixed as the end of the Lease and after delivery of entire possession of the demised premises to Owner. In the event of a sale of the land and building or leasing of the building, of which the demised premises form a part,
Owner shall have the right to transfer the security to the vendee or lessee and Owner shall thereupon be released by Tenant from all liability for the return of such security; and Tenant agrees to look to the new Owner solely for the return of said
security, and it is agreed that the provisions hereof shall apply to every transfer or assignment made of the security to a new Owner. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the monies deposited
herein as security and that neither Owner nor its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance.



Estoppel Certificate:



35. Tenant, at any time, and from time to time, upon at least 10 days prior notice by Owner, shall execute, acknowledge and deliver to Owner,
and/or to any other person, firm or corporation specified by Owner, a statement certifying that this Lease is unmodified and in full force and effect (or, if there have been modifications, that the same is in full force and effect as modified and
stating the modifications), stating the dates to which the rent and additional rent have been paid, and stating whether or not there exists any default by Owner under this Lease, and, if so, specifying each such default.



Successors and Assigns:



36. The covenants, conditions and agreements contained in this lease shall bind and inure to the benefit of Owner and
Tenant and their respective heirs, distributees, executors, administrators, successors, and except as otherwise provided in this lease, their assigns. Tenant shall look only to Owners estate and interest in the land and building, for the
satisfaction of Tenants remedies for the collection of a judgment (or other judicial process) against Owner in the event of any default by Owner hereunder, and no other property or assets of such Owner (or any partner, member, officer or
director thereof, disclosed or undisclosed), shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenants remedies under or with respect to this lease, the relationship of Owner and Tenant hereunder, or
Tenants use and occupancy of the demised premises.

39. RENTAL: The payments reserved under this Lease for the term hereof shall be and consist of the aggregate of:



(A) Minimum Rent during the term of the Lease shall be as
follows:



|             |  |                       |            |                        |   |          
|------------ |  | --------------------- | ---------- | ---------------------- | - | ---------
|Lease Months |  | Annual Minimum Rental |            | Monthly Minimum Rental
|1-60         |  | $                     | 320,178.00 |                        | $ | 26,681.50
|61-123       |  | $                     | 339,012.00 |                        | $ | 28,251.00



The first Lease
Year shall commence on the commencement date of this Lease (the Commencement Date), which shall be the earlier of (a) the date of substantial completion by Landlord of the Landlords Base Building Work or (b) the date that
Tenant first occupies the Demised Premises, and shall end with the expiration of the next succeeding twelve (12) months, plus the number of days, if any, required to have the period end at the expiration of the calendar month, and each succeeding
Lease Year shall run concurrently with each succeeding period of twelve (12) calendar months.





---

The first Lease Month shall commence on (a) the Commencement Date, if said date falls on the
first day of the first month of the Lease, or (b) if the Commencement Date does not fall on the first day of the first month, the first Lease Month shall begin on the first day of the first full month beginning after the Commencement Date. If the
Commencement Date is not the first day of a month, the rent for the fractional portion of the month preceding the first Lease Month shall be calculated on a pro-rata basis, based on the Minimum Rent payable during the first Lease Month, beginning
with and including the Commencement Date through the last day of that month, using the actual number of days in that month and Minimum Rent for said fractional period shall be payable upon Tenants Lease execution together with the first full
monthly Minimum Rent payment.



Tenant shall, at Landlords
option, within five (5) days of written request made by Landlord to Tenant, execute the certificate (the Landlords Base Building Work Certificate) annexed hereto as Exhibit D certifying the exact date of substantial
completion by Landlord of Landlords Base Building Work in the Demised Premises, the Commencement Date, Rent Commencement Date and Expiration Date of this Lease, and such dates shall be deemed conclusive for purposes of this Article and this
Lease. The failure by Tenant to so execute the Landlords Base Building Work Certificate in good faith by the date so specified above shall constitute a default by Tenant under this Lease.



The expiration date of this Lease and the end of the term of this Lease shall
be the last day of the one hundred twenty third (123rd) Lease Month following the last day of the month in which the day next preceding the Commencement Date occurs (the Expiration Date).



Minimum Rent shall be payable in advance, on the first (1st) day of each
calendar month during the term of this Lease. Tenant shall pay such Minimum Rent to Landlord, in advance, without any set-off, offset, abatement or deduction whatsoever and without notice or demand, in lawful money of the United States of America,
by check made payable to K/B Realty Advisors, Inc-261 Fifth Avenue, and delivered or sent by United States Mail (first class or express) addressed to K/B Realty Advisors, Inc-261 Fifth Avenue, c/o Harris Bank, 33450 Treasury Center, Chicago,
Illinois 60694-3500 or to such other place or to such other person as Landlord may designate from time to time by written notice to the Tenant. If this Lease commences or ends on a day other than the first day of a calendar month, then the rental
for such partial month shall be prorated on the basis of the number of days elapsed for said month.



Tenants obligation to pay Minimum Rent shall commence (the Rent Commencement Date) on the first (1st) day of the fourth (4th) full Lease
Month of the Lease. If the Commencement Date is not the first day of a month, the rent for the fractional portion of the month preceding the first Lease Month shall be calculated on a pro-rata basis, based on the Minimum Rent payable during the
first Lease Month, beginning with and including the Commencement Date through the last day of that month, using the actual number of days in that month and Minimum Rent for said fractional period shall be payable upon Tenants Lease execution
together with the first full monthly Minimum Rent payment (and Minimum Rent for said fractional period shall not be abated hereunder). Notwithstanding the foregoing, Tenant acknowledges and agrees that the Electric Inclusion Amount (as such term is
hereinafter defined) portion of the Minimum Rent shall be due and payable commencing on the Commencement Date of this Lease and there shall be no abatement whatsoever of the obligation of Tenant to pay the Electric Inclusion Amount portion of the
Minimum Rent from and after the Commencement Date of the Lease. Except as hereinabove described, there shall be no abatements of Minimum Rent or Additional Rent under this Lease.



(B) Additional Rent, consisting of all such other sums of money as shall become due from and payable by Tenant
to Landlord hereunder (for default in payment of which Landlord shall have the same remedies as a default in payment of Minimum Rent).



(C) The obligation of Tenant to pay all sums of Additional Rent and electricity charges (including, without limitation, the Electric Inclusion Amount) to
Landlord shall commence on the Commencement Date of the Lease and there shall be no abatement whatsoever of the obligation of Tenant to pay all sums of Additional Rent and electricity charges (including, without limitation, the Electric Inclusion
Amount) during any period or part of any Lease Year during the term of the Lease.

(H) All of Tenants Work shall be done in such a manner
so as not to interfere with, delay, or impose any additional expense upon Landlord in the maintenance or operation of the Building. In no event shall Landlord be required to consent to any of Tenants Work which would physically affect any part
of the Building outside of the Demised Premises or would, in Landlords sole judgment, adversely affect the proper functioning of any of the mechanical, electrical, sanitary or other systems of the Building. The approval by Landlord of any of
Tenants plans and specifications shall not constitute an assumption of any liability on the part of the Landlord for their accuracy or their conformity which applicable law, and Tenant shall be solely responsible therefor. Approval by Landlord
of any Tenants plans and specifications shall not constitute a waiver by Landlord of the right to thereafter require Tenant to amend same to provide for omissions therein later discovered by Landlord; and



(I) Subject to the terms and conditions set forth below, Landlord shall
reimburse Tenant up to a maximum amount of $188,340.00 (Landlords Contribution) for costs incurred and actually expended by Tenant in connection with Tenants initial installation in the Demised Premises for the conduct of its
business (including architectural, engineering, expediting and other consulting fees, and all necessary building department permits and approvals, but not including personal property not constituting a permanent leasehold improvement) (collectively,
the Tenants Initial Installation). Tenants Initial Installation shall be deemed to be a part of the Tenants Work. Notwithstanding anything to the contrary set forth in this Lease, Tenant unconditionally acknowledges and
agrees that no more than $28,251.00 of the Landlords Contribution may be used by Tenant for the payment of construction-related soft costs (which includes architectural fees, engineering fees, expediting and other consulting fees and permit
and filing fees) and mill work associated with the Tenants Initial Installation. Tenant herein acknowledges and agrees that Tenants Initial Installation in the Demised Premises shall be done by Tenant so as to comply in all respects with
any and all requirements of the Americans With Disabilities Act and Tenant shall ensure that the Demised Premises shall fully comply with this law during the entire term of this Lease. Landlord shall disburse from time to time, but not more often
than once in any thirty (30) day period, within ten (10) business days after receipt of Tenants request therefor, that portion of Landlords Contribution equal to the amount set forth in Tenants reimbursement requisition; provided
however, that no reimbursement requisition shall be made if, and for so long as, Tenant shall be in monetary default under this lease or non-monetary default under this Lease beyond any applicable notice and cure period. No reimbursement requisition

(1) A certificate signed by Tenant and Tenants architect, and a fully-completed, fully-executed AIA Form G702, also signed by Tenant and
Tenants architect, dated not more than ten (10) days prior to such request, setting forth (a) the sum which was previously paid to all contractors, subcontractors, materialmen, engineers, architects and other persons who have rendered services
or furnished materials in connection with Tenants Initial Installation, (b) a brief description of such services and materials and the amounts previously paid and which are to be reimbursed to Tenant from such reimbursement requisition, (c)
that the work described in the certificate has been completed substantially in accordance with the final plans which were approved in writing by the Landlord (this statement need not be made by Tenant, only by Tenants architect), (d) that
there has not been filed with respect to the Demised Premises or the Building or any part thereof or any improvements thereon, any vendors, mechanics, laborers, materialmens or other like liens arising out of Tenants
Initial Installation which has not been discharged of record, and (e) that Tenant has complied with all of the conditions set forth in this Lease applicable to alterations, including the requirement that Tenant comply with all applicable law
(statements (d) and (e) need not be made by Tenants architect, only by Tenant);



(2) Partial lien waivers in recordable form, paid receipts, paid invoices and such other proof of payment as Landlord shall reasonably require for all work done and materials supplied and amounts paid to such vendors

Landlord shall reasonably require for all work done and materials supplied and amounts paid to such vendors prior to and with respect to amounts and payments covered by the current requisition, and until Landlord has also received from Tenants
architect all certificates of final approval required by any governmental or quasi - governmental body in respect of Tenants Initial Installation. Following completion of Tenants Work and the Tenants Initial Installation, Tenant
shall cause Tenants architect to obtain and such architect shall be responsible for obtaining final approval of Tenants Work and the Tenants Initial Installation from the New York City Department of Buildings and other regulatory
bodies having jurisdiction. In addition, Tenant shall be required to sign a written statement in form satisfactory to Landlord acknowledging the total cost of Tenants Initial Installation and further acknowledging that all contractors,
subcontractors, materialmen, engineers, architects and other persons who have rendered services or furnished materials in connection with Tenants Initial Installation have been previously paid in full. Notwithstanding anything to the contrary
set forth in this Lease, the Tenant acknowledges that if the final ten percent (10%) of Landlords Contribution has not been drawn down by the Tenant or reimbursed to the Tenant within three hundred sixty (360) days of the Commencement Date of
this Lease, then Tenant shall be deemed to have unconditionally and forever forfeited any rights to the final ten percent (10%) of Landlords Contribution and Landlord shall be entitled to retain said sum.



(K) Any modifications, changes or alterations to the Class E fire safety
system for the floor in the Building on which the Demised Premises are located ( Fire Safety System) which are performed after the Commencement Date, including without limitation, installing speakers, strobes and pull stations, making
modifications to the reentry door(s) and making other Class E installations and hookups and making modifications to said Fire Safety System, shall be performed by Tenant at its sole cost and expense and shall be deemed to be a part of the
Tenants Initial Installation. The work to be performed by Tenant in and to the Fire Safety System shall be described in Tenants plans and specifications therefor and shall be reimbursed as part of Landlords Contribution. Prior to
the date of Tenants initial occupancy of the Demised Premises, Tenant shall deliver to the Landlord written proof consisting of a letter issued by the Buildings Fire Safety System vendor/service provider indicating that all Fire Safety
System devices located on the floor on which the Demised Premises are located are functioning properly. At such time that the foregoing is provided, Tenant shall also deliver to Landlord a schedule indicating the dates for the pre-testing and final
testing of the Fire Safety System, with said schedule to provide for final testing to be completed no later than six (6) months from the date of the initial filing of plans for the Tenants Premises Initial Installation with the Building

to the Landlord and its engineer for its written approval and comment thereto (with such approval and comment thereto not to be unreasonably withheld, delayed or conditioned) the specifications outlining the design and modifications to be made
by the Tenant to the Fire Safety System for the floor on which the Additional Demised Premises are located. Once Landlord and its engineer approve in writing said plans and specifications for the modification of the Fire Safety System, same shall be
forwarded to the service provider for the Fire Safety System. The parties agree that the costs incurred in connection with the modification kit for the Fire Safety System for the floor on which the Demised Premises are located shall be paid by
Tenant as Additional Rent within ten (10) days of being billed therefor by the Landlord.

Tenant herein acknowledges that Landlord may, at its sole option, elect to use any portion of the
Landlords Contribution in order to correct and/or remedy any violations assessed due to Tenant failure to modify or alter the Fire Safety System in compliance with applicable law or otherwise to remedy any noncompliance by Tenant with any of
its covenants or undertakings as provided for in the Lease. If Landlord elects to do any or all of the foregoing, then Tenant herein authorizes Landlord and grants to Landlord an irrevocable power of attorney to complete and execute any forms or
documents on Tenants behalf which may be necessary or required in order to perform any of the foregoing. Notwithstanding the foregoing, Tenant acknowledges that Landlord shall have no legal obligation to do any of the foregoing and the sole
responsibility and legal obligation for same shall rest solely with Tenant.



41. ELECTRICITY:



Section 41.1.
Landlord shall furnish the electric energy that Tenant reasonably requires in the Demised Premises on a rent inclusion basis. That is, the Minimum Rent includes the Electric Inclusion Amount, which the parties agree is $18,834.00 per
Lease Year, $1,569.50 per month (which sum is equal to $3.00 per rentable square foot in the Demised Premises) (as adjusted pursuant to this Article 41), and which the parties have agreed is the reasonable value to Tenant of normal electric service
for lighting, light office equipment and the usual small business machines (including facsimile machines, personal computers and photocopying machines) during normal weekday operating hours of the Building. Accordingly, there shall be no charge to
Tenant for such electric energy by way of measuring the same on any meter or otherwise, such electric energy being included in Landlords services which are covered by the Minimum Rent. Landlord shall not be liable in any way to Tenant for any
interruption or failure of or defect in the supply or character of electric energy furnished to the Demised Premises (other than due to the gross negligence or willful misconduct of Landlord or its officers, agents, contractors or employees) or for
any loss, damage or expense Tenant may sustain if either the quantity or character of electric service is changed or is no longer suitable for Tenants requirements, whether by reason of any requirement, act or omission of the public utility
serving the Building with electricity or for any other reason.



Section 41.2. Tenant shall at all times comply with the rules, regulations, terms and conditions applicable to service, equipment, wiring and requirements of the public utility supplying electricity to the Building. Tenant agrees
that at no time will the connected electrical load in the Demised Premises exceed in the aggregate six (6) watts demand load per useable square foot of the Demised Premises (excluding HVAC). Tenant shall not, without Landlords prior written
consent in each instance, connect any fixtures, machinery, appliances or equipment to the building electric distribution system or make any alteration or addition to Tenants machinery, appliances or equipment, or the electric system of the
Demised Premises, if the effect thereof would be to increase the electrical load in the Demised Premises over the load specified in this Section 41.2 or in Section 41.4. Should Landlord grant such consent, all additional risers or other equipment
required therefor shall be provided by Landlord and the cost thereof (including a connection fee of $350 per kilovolt ampere) shall be paid by Tenant within thirty (30) days after Landlords written demand.



Section 41.3. If the public utility rate schedule for the supply of
electric energy to the Building and/or the surcharge for fuel cost or any other charge made by the public utility supplying electric energy to the Building and/or the taxes payable by Landlord with respect to such electric energy are increased after
the date of this Lease and/or the service classification at which Landlord purchases electric energy is changed after the date of this Lease resulting in an increase in the cost to Landlord of electrical energy, the Minimum Rent shall be increased
by an amount equal to the product of (i) the then-existing Electric Inclusion Amount and (ii) the percentage increase in such public utility rate schedule, fuel adjustment or other charge, taxes or cost. Any such increase shall be effective as of
the date of such increase and shall be made retroactively if necessary. Upon the request of either party, Landlord and Tenant shall execute a supplementary agreement (in form reasonably approved by Tenant) confirming the aforesaid increase. In no
event shall the provisions of this Section 41.3 operate to reduce the Minimum Rent below the amount stated in Article 39 nor the Electric Inclusion Amount below the amount stated in this Article.



Section 41.4. The Electric Inclusion Amount is based upon
Landlords assumption that Tenants initial electrical installation will not result in a total connected electrical load for lighting, and equipment will not be in excess of, six (6) watts demand load per useable square foot of the



6



---

Demised Premises (excluding HVAC) and that Tenant will, except for the purpose of office cleaning, use electrical energy only during normal weekday operating
hours of the Building. Accordingly, if Tenants initial electrical installation exceeds such criteria, or if from time to time Tenant makes material use of electricity during hours other than normal weekday operating hours of the Building, or
if from time to time Tenant after completion of its initial installation adds or changes any machinery, appliances or equipment which increases the aggregate electrical load in the Demised Premises, the Electric Inclusion Amount and the Minimum Rent
shall from time to time be equitably adjusted to reflect the resulting increase in such use. In addition, Landlord shall have the right to conduct a periodic survey of Tenants actual electrical usage and increase the Electric Inclusion Amount
if the survey indicates the Tenants usage of electricity exceeds the cost of $3.00 per rentable square feet of the Demised Premises. Landlord shall furnish a statement of Landlords determination as to the amount of the adjustment, and
the same shall become binding upon the parties unless, within thirty (30) days, Tenant notifies Landlord that it disputes the amount of such adjustment, in which event the parties shall in good faith make reasonable attempts to come to agreement,
and, if Landlord and Tenant cannot agree thereon, the amount of such adjustment shall be determined, based on standard practices, by an independent electrical consultant selected by Landlord. Tenant shall permit said consultant to have access to the
Demised Premises and Tenants electrical facilities for the foregoing purpose at all reasonable times. The fee of such consultant shall be paid by Tenant unless such consultant finds that Tenants use does not justify an increase in
Minimum Rent, in which case the fee shall be paid by Landlord. When the amount of such adjustment is so determined, Landlord and Tenant shall execute a supplementary agreement to reflect such adjustment, which shall be effective from the date of the
increase of such usage as determined by such electrical consultant and shall be made retroactively if necessary. Any adjustment shall be effective even if such supplementary agreement (in form reasonably approved by Tenant) is not executed and
delivered. Pending the determination of the adjustment, Tenant shall pay to Landlord the amount of such adjustment as specified in Landlords statement. Thereafter, if it is determined that Tenant has overpaid, Tenant shall receive a credit
against Minimum Rent in the amount of the overpayment, said credit to be applied against the next accruing installment(s) of Minimum Rent.



Section 41.5. Landlord reserves the right to discontinue furnishing electric energy to the Demised Premises at any time upon not less than ninety
(90) days notice to Tenant provided that Landlord shall not exercise such right unless it discontinues furnishing electricity to a substantial portion of the Building, except that if Tenant, despite its diligent efforts, shall be unable to obtain
electric service from the public utility within such 90-day period, Landlord shall continue to furnish electricity to Tenant until such time as Tenant would have been able to obtain such electricity had Tenant continued to exercise its diligent
efforts to do so. If Landlord exercises such right of termination, this Lease shall continue in full force and effect and shall be unaffected thereby, except only that, from and after the effective date of such discontinuance, Landlord shall not be
obligated to furnish electric energy to Tenant, and the Minimum Rent payable under this Lease shall be reduced by the Electric Inclusion Amount then in effect. If Landlord voluntarily discontinues furnishing electric energy to Tenant, Landlord
shall, prior to the effective date of such discontinuance, at Landlords expense, make such changes in panel boards, feeders, risers, wiring and other conductors and equipment to the extent required to permit Tenant to obtain electric energy
directly from the public utility company. If, on the other hand, Landlord is required by any legal requirements to discontinue furnishing electric energy to Tenant, Landlord shall make such changes in panel boards, feeders, risers, wiring and other
conductors and equipment in order to permit Tenant to obtain electric energy directly from the public utility company.



Section 41.6. If any tax is imposed upon Landlord with respect to electrical energy furnished as a service to Tenant by any government authority,
Tenant agrees that, where permitted by law or applicable regulations, Tenants pro rata share of such taxes shall be reimbursed by Tenant to Landlord upon demand.



Section 41.7. Landlord shall have the option of installing submeters at Landlords expense to measure
Tenants consumption of electrical energy. If Landlord exercises such option, the Minimum Rent shall be reduced by an amount equal to the then Electric Inclusion Amount with such reduction to be effective as of the commencement of the operation
of such submeters and, commencing at such time, Tenant shall pay to Landlord, as Additional Rent, on demand made from time to time but no more frequently than monthly, for its use of electrical energy in the Demised



7



---

Premises, based upon both consumption and demand factors, at the seasonally adjusted rate then payable by Landlord to the utility company, plus an amount
equal to fifteen (15%) percent thereof to reimburse Landlord for its overhead, administration and supervision in connection therewith. For the purposes of this Section 41.7, the rate to be paid by Tenant in the event of submetering shall include any
taxes, energy charges, demand charges, fuel adjustment charges, rate adjustment charges or other charges actually imposed in connection therewith. If any tax is imposed upon Landlords receipts from the sale or resale of electrical energy to
Tenant by any federal, state, city or local authority, the pro rata share of such tax allocable to the electrical energy service received by Tenant shall be passed on to and paid by Tenant as Additional Rent upon Landlords demand therefor, if
and to the extent permitted by law.



Section 41.8.
Landlord shall not in any way be liable or responsible to Tenant for any loss or damage or expense which Tenant may sustain or incur if either the quantity or character of electric service is changed or is no longer available or suitable for
Tenants requirements. Tenants use of electric current in the Demised Premises shall not at any time exceed the capacity of any of the electrical conductors and facilities in or otherwise serving the Demised Premises. In order to insure
that such capacity is not exceeded and to avert any possible adverse effect upon the Buildings electric service, Tenant shall not, without Landlords prior written consent in each instance, connect any fixtures, appliances or equipment
(other than a reasonable number of table or floor lamps, typewriters, word processors, small computers, photocopy machines and similar small office machines using comparable electric current) to the Buildings electric distribution system nor
make any alteration or addition to the electric system of the Demised Premises. Should Landlord grant such consent, which consent may be granted or refused in Landlords sole discretion, all additional risers or other equipment required
therefor shall be provided by Landlord upon notice to Tenant, and all costs and expenses in connection therewith, including, without limitation, those for filing and supervision, shall be paid by Tenant on demand. In addition, the provisions of
Section 41.2 and all other provisions of this Article shall be binding on the Tenant. In addition, as a condition to granting such consent, Landlord may require Tenant to agree to an increase in the Additional Rent by an amount which will reflect
the value to Tenant of the additional service to be furnished by Landlord, to wit: the potential additional electrical current to be made available to Tenant based upon the estimated initial total capacity of such additional risers or other
equipment. If Landlord and Tenant cannot agree on the amount of such Additional Rent increase, the same shall be determined by a reputable electrical consultant, to be selected by Landlord and paid by Tenant. The parties shall then execute an
agreement prepared by Landlord amending this Lease and setting forth the new Additional Rent resulting from such increase and confirming the effective date thereof, but such increase shall be effective from such date even if such agreement is not
executed.



42. TAX ESCALATION:



(A) As used in this Lease:



(i) Taxes shall mean the sum of the (i) real
estate taxes and assessments and special assessments imposed upon the Building and/or the land on which the Building is situated by any governmental bodies or authorities (the Land) and any rights or interests appurtenant thereto payable
by Landlord during any Tax Year and (ii) attorneys fees, court, or other administrative costs and disbursements incurred by Landlord in connection with any reduction in Taxes which is obtained prior to the date such Taxes are payable. If at
any time during the term of this Lease the methods of taxation prevailing at the commencement of the term hereof shall be altered so that in lieu of, or as an addition to or as a substitute for the whole or any part of the taxes, assessments,
levies, impositions or charges now levied, assessed or imposed on real estate and the improvements thereof, there shall be levied, assessed and imposed (a) a tax, assessment, levy or otherwise on the rents received therefrom, or (b) a license fee
measured by the rent payable by Tenant to Landlord, or (c) any other such additional or substitute tax, assessment, levy, imposition or charge, then all such taxes, assessments, levies, impositions or charges or the part thereof so measured or
based shall be deemed to be included within the term Taxes for the purpose hereof. In no event shall Taxes include income, inheritance, franchise, gross receipts or other similar taxes. A copy of the tax bill of The City of
New York or other taxing authority imposing Taxes on the Land or the Building shall be sufficient evidence of the amount of Taxes. Notwithstanding the fact that the aforesaid Additional Rent is measured by Taxes, such amount is Additional Rent and
shall be paid by Tenant

---

as provided herein regardless of the fact that Tenant may be exempt, in whole or in part, from the payment of any Taxes for any reason whatsoever.



(ii) Base Tax shall mean Taxes,
as finally determined, for the fiscal period of July 1, 2000 through June 30, 2001.



(iii) Tax Year shall mean the fiscal year commencing on July 1 and ending on June 30 (or such other period as hereinafter may
be duly adopted by the City of New York as its Fiscal Year for real estate tax purposes), any portion of which fiscal period occurs during the term of this Lease.



(iv) Tenants Share shall be [TO BE PROVIDED] %.



(B) (i) If the Taxes for any Tax Year shall be more than the Base Tax, Tenant
shall pay as Additional Rent for such Tax Year an amount equal to Tenants Share of the amount by which the Taxes for such Tax Year are greater than the Base Tax (the amount payable by Tenant is hereinafter called the Tax Payment).
The Tax Payment shall be prorated, if necessary, to correspond with that portion of a Tax Year occurring within the term of this Lease. At Landlords sole option, the Tax Payment shall either (1) be payable by Tenant within ten (10) days after
receipt of a demand from Landlord therefor or (2) shall be payable by Tenant to Landlord in equal monthly installments on the first day of each month in an amount as reasonably estimated by the Landlord, and shall in any event be adjusted from time
to time with such adjusted amount being remitted by Tenant to Landlord upon Landlords written demand therefor.



(ii) In the event the Base Tax is reduced as a result of an appropriate proceeding, Landlord shall have the right to adjust the amount of
Tax Payment due from Tenant for any Tax Year in which Tenant is or was obligated to pay a Tax Payment hereunder, and Tenant agrees to pay the amount of said adjustment on the next rental installment day immediately following receipt of a rent
statement from Landlord setting forth the amount of said adjustment. The parties acknowledge that in no event shall the Minimum Rent or Additional Rent ever be reduced as a result of a tax certiorari proceeding or as a result of any reduction in
Taxes or the Base Tax.



(C) Only Landlord shall be eligible to
institute tax reduction or other proceedings to reduce the assessed valuation of the Land and the Building, provided, however, that Tenant shall be required to make all Tax Payments due under this Article while any such proceedings are pending.
Should Landlord be successful in any such reduction proceedings and obtain a rebate for periods during which Tenant has paid its share of increases, Landlord shall after deducting its expenses, including attorneys fees and disbursements in
connection therewith, return Tenants Share of such rebate to Tenant.



(D) With respect to any period at the expiration of the term of this Lease which shall constitute a partial tax year, Landlords statement shall apportion the amount of the Additional Rent due hereunder. The
obligation of Tenant in respect to such Additional Rent applicable for the last year of the term of this Lease or part thereof shall survive the expiration of the term of this Lease.



43. ESCALATIONS: In addition to other sums due hereunder, Landlord and Tenant agree that Tenant shall pay to Landlord, as Additional
Rent, a three (3%) percent fixed rent increase in lieu of any operating expense or porters wage escalation. Such sums shall be payable commencing on the first day of the second Lease Year, and shall be payable monthly thereafter during the term of
this Lease. Payments hereunder for each Lease Year after the first Lease Year shall be in amounts equal to the sum of: (i) three (3%) percent of the Minimum Rent payable for the immediately preceding Lease Year (without regard to any abatement or
free rent); and (ii) the payment due under this Article for such immediately preceding Lease Year. The computation under this Article is intended to constitute a formula for an agreed rental escalation and the computation may or may not constitute
an actual reimbursement to Landlord for expenses in the nature of costs paid by or incurred by Landlord with respect to the Building.



44. WAIVER OF SUBROGATION: Each party hereby releases the other party (which term as used in this Article includes the employees, agents, officers and directors of
the other party) from all liability, whether for negligence or otherwise, in connection with loss covered by any fire and/or



9



---

extended coverage insurance policies, which the releasor carries with respect to the Demised Premises, or any interest or property therein or thereon
(whether or not such insurance is required to be carried under this lease), but only to the extent that such loss is collected under said fire and/or extended coverage insurance policies. Such release is also conditioned upon the inclusion in the
policy or policies of a provision whereby any such release shall not adversely affect said policies, or prejudice any right of the releasor to recover thereunder. Each party agrees that its insurance policies aforesaid will include such a provision
so long as the same shall be obtainable without extra cost, or if extra cost shall be charged therefor, so long as the party for whose benefit the clause or endorsement is obtained shall pay such extra cost. If extra cost shall be chargeable
therefor, each party shall advise the other thereof of the amount of the extra cost, and the other party at its election, may pay the same, but shall not be obligated to do so.



45. COMPLIANCE WITH LAWS: Supplementing the provisions of Article 6 hereof, Tenant shall give prompt notice to Landlord of any notice
it receives of the violation of any law or requirement of any public authority with respect to the Demised Premises or the use or occupation thereof. Tenant shall promptly comply with all present and future Jaws, orders and regulations of all state,
federal, municipal and local governments, departments, commissions and boards or any direction of any public officer pursuant to law and all orders, rules and regulations of the New York Board of Fire Underwriters or any similar body arising out of
Tenants use of the Demised Premises which shall impose any violation, order or duty upon Landlord or Tenant with respect to Tenants use or manner of use of the Demised Premises (in which event Tenant shall effect such compliance at its
sole cost and expense) or the Building (in which event, notwithstanding anything herein to the contrary, Landlord shall effect such compliance but Tenant shall promptly pay to Landlord Tenants Share, as defined in Paragraph 42(A) (iv), of the
cost thereof).



46. INDEMNITY-LIABILITY INSURANCE:



(A) Tenant covenants and agrees to indemnify and save Landlord harmless from
and against any and all claims arising during the term of this lease for damages or injuries to goods, wares, merchandise and property and/or for any personal injury or loss of life in, upon or about the Demised Premises, except such claims as may
be the result of the gross negligence of Landlord, its agents, employees or contractors.



(B) Tenant further covenants and agrees to indemnify Landlord against the cost of any increase in Landlords insurance rates resulting from Tenants use or manner of use of the Demised Premises. Tenant shall
reimburse Landlord for any such increase within fifteen (15) days after Landlord bills Tenant therefor.



(C) Tenant covenants to provide on or before the commencement of the term hereof and to keep in force during the term hereof for the benefit of Landlord
and Tenant a comprehensive policy of liability insurance protecting Landlord, Tenant and any and all of Landlords designees against any liability whatsoever occasioned by accident on or about the Demised Premises or any appurtenances thereto.
Such policy is to be written by good and solvent insurance companies satisfactory to Landlord of at least a Bests Rating of A+ or better, and the amounts of liability thereunder shall not be less than the amount of $3,000,000 in
respect of any one person, in the amount of $6,000,000 in respect of any one accident, and in the amount of $1,000,000 in respect of property damage. The aforesaid insurance policy or a certificate evidencing such insurance shall name Landlord, Koll
Bren Schreiber Realty Advisors, Inc., Jones Lang LaSalle Partners, Landlords mortgagee and other designees as additional insureds under such policy and said policy shall be delivered to Landlord upon Tenants execution of this
Lease. Prior to the time such insurance is first required to be carried by Tenant, and thereafter at least thirty (30) days prior to the expiration of any such policy, Tenant agrees to deliver to Landlord either a duplicate original of the aforesaid
policy or a certificate evidencing such insurance and meeting the requirements of this Article, provided said certificate contains an endorsement that such insurance may not be canceled or modified except upon thirty (30) days prior written notice
to Landlord, together with evidence of payment for the policy. Tenants failure to provide and keep in force the aforementioned insurance shall be regarded as a material default hereunder, entitling Landlord to exercise any or all of the
remedies as provided in this Lease in the event of Tenants default.

47. ASSIGNMENT, SUBLETTING, MORTGAGING:



(A) Tenant will not by operation of law or otherwise, assign, mortgage or encumber this Lease, nor sublet or permit the
Demised Premises or any part thereof to be used by others, without Landlords prior express written consent in each instance. Any transfer, by operation of law or otherwise, of Tenants interest in this Lease (in whole or in part) or of a
fifty (50%) percent or greater interest in Tenant (whether stock, partnership interest or otherwise) shall be deemed an assignment of this Lease within the meaning of this Article. (The issuance of shares of stock to other than the existing
shareholders shall be deemed to be a transfer of such stock for the purposes of this Article.) If there has been a previous transfer of less than a fifty (50%) percent interest in Tenant during the term of this Lease, any other transfer of an
interest in Tenant which would then result in an aggregate transfer of greater than a fifty (50%) percent interest in Tenant shall be deemed an assignment of Tenants interest in this Lease within the meaning of this Article.



(B) (i) In the event that Tenant shall at any time or times during the term
of this Lease desire to assign this Lease or sublet all or any part of the Demised Premises, Tenant shall give notice (the Assignment/Sublet Notice) thereof to Landlord, which notice shall be accompanied by (a) at Tenants option,
either a conformed or photostatic copy of the proposed assignment or sublease agreement (provided, however that such proposed assignment or sublease agreement need not be in executed form if accompanied by a writing signed by Tenant and the proposed
assignee or sublessee indicating their intent to enter into the proposed assignment or sublease upon Landlord consenting thereto), or a copy of a letter of intent (the Letter of Intent) executed by or on behalf of Tenant and the proposed
assignee or subtenant setting forth the material business terms of the proposed assignment or sublease, in either event, the effective or commencement date of which shall be at least thirty (30) days after the giving of such notice, (b) 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, (c) current financial information with respect to the proposed assignee or subtenant,
including, without limitation, its most recent financial report or statement (if same exists, and if not, the equivalent information in a form reasonably satisfactory to Landlord), and (d) such other information as Landlord may reasonably request.
Such notice shall be deemed an offer from Tenant to Landlord whereby Landlord (or Landlords designee) may, at its option: (i) terminate this Lease (if the proposed transaction is an assignment or sublease of all or substantially all of the
Demised Premises), or (ii) terminate this Lease with respect to the space covered by the proposed sublease (if the proposed transaction is a sublease of part of the Demised Premises for all or substantially all of the remainder of the term of this
Lease, i.e., the term of which expires during the final eighteen (18) months prior to the Expiration Date). For purposes of this paragraph, substantially all of the Demised Premises shall mean more than seventy (70%) percent thereof.
Said options may be exercised by Landlord by notice to Tenant at any time within thirty (30) days after Landlords receipt of the Assignment/Sublet Notice, together with all other documentation and information required pursuant to this
paragraph to be given by Tenant to Landlord (Recapture Period); and during such Recapture Period Tenant shall not assign this Lease or sublet such space to any person. Following the expiration of the Recapture Period, Tenant shall have
thirty (30) days to submit to Landlord Tenants written request for Landlords consent to a proposed assignment or sublease on the same terms and conditions as were contained in the proposed assignment or sublease or the Letter of Intent,
which was previously submitted to Landlord pursuant to this Section, whichever is applicable. In the event that Tenant fails to submit such written request for Landlords consent as set forth in the preceding sentence within such thirty (30)
day period, then in connection for with any request for Landlords consent to such proposed assignment of this Lease or proposed subletting of the Demised Premises or any portion thereof submitted after such thirty (30) day period, Tenant will
be required to comply with all of the requirements of this paragraph and Landlord shall have all the options under this paragraph.



(ii) If Landlord exercises its option to terminate this Lease in the event that Tenant desires either to assign this Lease or to sublet
all or substantially all of the Demised Premises, then this Lease shall end and expire upon the date that such assignment or subletting was to be effective or to commence, as the case may be, and the Minimum Rent and Additional Rent shall be paid
and apportioned to such date. If Landlord exercises its option to terminate this Lease as to a portion of the Demised Premises in the event that Tenant desires to sublet a portion of the Demised Premises,



11



---

then this Lease, with respect to the portion of the Demised Premises affected by such subletting, shall end and expire upon the date that such subletting was
to commence, the Minimum Rent payable hereunder and the Additional Rent payable pursuant to this Lease hereof shall be adjusted in proportion to the portion of the Demised Premises affected by such termination and Tenant shall at its sole cost and
expense (and prior to the effective date of such sublease) erect such demising walls as are necessary to separate the terminated portion of the Demised Premises from the remainder of the Demised Premises and to provide access thereto.



(iii) In the event that Tenant complies with the provisions
of this subparagraph of this Article and Landlord does not exercise an option provided to it thereunder within the time provided therefor, and provided that Tenant is not in default of any of Tenants obligations under this Lease,
Landlords consent (which must be in writing and in form reasonably satisfactory to Landlord) to the proposed assignment of this Lease or subletting of a portion or all of the Demised Premises shall not be unreasonably withheld or delayed,
provided the following conditions have been satisfied:

(5) the proposed assignee or subtenant shall not be (i) a government or any
subdivision or agency thereof or quasi governmental agency or court of law, (ii) a school, college, university or educational institution of any type, whether for profit or nonprofit, (iii) an employment or placement agency or executive recruitment
office, or (iv) a provider of medical services of any kind or a medical office;



(6) Tenant shall have submitted to Landlord a fully executed counterpart of the proposed assignment or the proposed sublease, as the case may be, and the form of the same shall be reasonably satisfactory to Landlord

12



---

listed or publicized the Demised Premises for subletting or assignment, with a broker, agent or representative or otherwise, in a newspaper or trade
publication, at a proposed rental less than the Minimum Rent and Additional Rent at which Landlord is then offering to Lease other space in the Building;



(10) the sublease shall not provide for an option on behalf of the subtenant thereunder to extend or renew the term of such sublease and shall also not
grant to subtenant any space option or other option set forth in this Lease (which option(s) is (are) only granted to the original Tenant hereunder);



(11) such subletting shall not result in there being more than two (2) occupants of the Demised Premises, including Tenant; and



(12) solely for a period of one hundred eighty (180) days, Tenant shall
employ Landlords then leasing agent as its sole and exclusive agent to effectuate any sublease or assignment.



(iv) Each subletting pursuant to this Article shall be subject to all of the covenants, agreements, terms, provisions and conditions
contained in this Lease. Notwithstanding any such subletting and/or acceptance of Minimum Rent or Additional Rent by Landlord from any subtenant, Tenant shall and will remain fully liable for the payment of the Minimum Rent and Additional Rent due,
and to become due, hereunder, for the performance of all of the covenants, agreements, terms, provisions and conditions contained in this Lease on the part of Tenant to be performed and for all acts and omissions of any licensee, subtenant, or any
other person claiming under or through any subtenant that 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.

(vi) If Landlord shall give its consent to
any assignment of this Lease or to any sublease, Tenant shall, in consideration therefor, pay to Landlord, as Additional Rent:



(a) in the case of an assignment, an amount equal to seventy five (75%) percent of all sums and other consideration payable to Tenant by the assignee for,
or by reason of, such assignment, including, without limitation, all sums payable for the sale of Tenants fixtures, Leasehold improvements, equipment, furniture, furnishings, or other personal property; and



(b) in the case of a sublease, seventy five (75%) percent of any rents,

square foot payable by Tenant hereunder) pursuant to the terms hereof, including, without limitation, all sums paid for the sale or rental of Tenants fixtures, leasehold improvements, equipment, furniture or other personal property.



The sums payable under this paragraph (vi)
shall be paid to Landlord as and when payable by the subtenant to Tenant.



(vii) If Tenant (or any subtenant) is a corporation, the provisions of subparagraph (A) of this Article shall apply to a transfer (however accomplished, whether in a single transaction or in a series of related or
unrelated transactions) of stock (or any other mechanism such as, by way of



13



---

example, the issuance of additional stock, a stock voting agreement or change in class (es) of stock) which results in a change of control of Tenant (or such
subtenant) as if such transfer of stock (or other mechanism) which results in a change of control of Tenant (or such subtenant) were an assignment of this Lease, and if Tenant (or such subtenant) is a partnership, limited liability company or joint
venture, said provisions shall apply with respect to a transfer (by one or more transfers) of an interest in the distributions of profits and losses of such partnership, joint venture or limited liability company (or other mechanism, such as, by way
of example, the creation of additional general partnership or limited partnership interests or limited liability company interests) which results in a change of control of such partnership or joint venture or limited liability company, as if such
transfer of an interest in the distributions of profits and losses of such partnership or joint venture or limited liability company which results in a change of control of such partnership or joint venture or limited liability company were an
assignment of this Lease; but the provisions of subparagraph (A) of this Article hereof shall not apply to transactions with (u) a corporation into or with which Tenant is merged or consolidated, (v) a corporation, partnership or other entity to

such transfer is a reputable entity of good character and has a net worth computed in accordance with generally accepted accounting principles at least equal to the Minimum Net Worth (as defined below), (ii) proof reasonably satisfactory
to Landlord of such net worth shall have been delivered to Landlord at least ten (10) days prior to the effective date of any such transaction, (iii) in the event that the Tenant hereunder immediately after such transfer is other than the Tenant
herein named, a duplicate original instrument of assignment in form and substance reasonably satisfactory to Landlord, duly executed by Tenant, shall have been delivered to Landlord at least ten (10) days prior to the effective date of any such
transaction, (iv) in the event that the Tenant hereunder immediately after such transfer is other than the Tenant herein named (a New Tenant), an instrument in form and substance reasonably satisfactory to Landlord, duly executed by such
New Tenant, in which such New Tenant 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

control, directly or indirectly, of more than fifty percent (50%) of all the voting stock, and in case of a joint venture or partnership or similar entity, ownership, directly or indirectly, of more than fifty percent (50%) of all the general or
other partnership (or similar) interests therein. Any agreement pursuant to which (x) Tenant is relieved from the obligation to pay all or a part of Minimum Rent or Additional Rent under this Lease, and (y) a third party undertakes or is granted any

subparagraph (A) hereof. For purposes of this subparagraph, the term Minimum Net Worth shall mean the greater of (i) the average net worth of Tenant for the twelve (12) month period which immediately precedes such transfer or (ii)
Tenants net worth as of the date hereof. Notwithstanding anything to the contrary contained herein, the transfer of stock to any family member or members of the shareholders of Tenant who as of the date hereof own a minimum of fifty-one (51%)
percent of the outstanding shares of Tenant (the Major Shareholders), or to any trust established for the benefit of one or more of the family members of the Major Shareholders shall not in any event be treated as an assignment of this
Lease and Landlords consent shall not be required therefor but at least 30 days prior written notice of such stock transfer shall be delivered to the Landlord and a copy of the relevant trust documentation and/or estate planning instruments
shall be delivered to Landlord at least 30 days prior to the effective date of such stock transfer.



(C) Each permitted assignee shall assume and be deemed to have assumed this Lease and shall be and remain liable jointly and severally with Tenant for the
payment of the Minimum Rent and Additional Rent and for the due performance of all the terms, covenants, conditions and agreements herein contained on Tenants part to be performed for the term of this Lease and any renewals and modifications
hereof. No assignment shall be binding on Landlord unless, as



14



---

hereinbefore provided, such assignee or Tenant shall deliver to Landlord a duplicate original of the instrument of assignment which contains a covenant of
assumption by the assignee of all of the obligations aforesaid and shall obtain from Landlord the aforesaid written consent prior thereto. Any assignment, sublease or agreement permitting the use and occupancy of the premises to which Landlord shall
not have expressly consented in writing shall be deemed null and void and of no force or effect.



(D) Tenant agrees that notwithstanding any subletting or assignment permitted by Landlord, no other and further subletting of the Demised Premises by
Tenant or any person or entity claiming through or under Tenant shall or will be made except upon compliance with and subject to the provisions of this Article.



48. TENANTS CERTIFICATE: Tenant shall, without charge at any time and from time to time, within seven (7) days after written request by Landlord, certify
by written instrument, duly executed, acknowledged and delivered and given with the express knowledge that any party may rely on the information set forth in said instrument, to any mortgagee, assignee of any mortgage or to any purchaser, or any
proposed mortgagee, assignee of any mortgage or purchaser, or any other person, firm or corporation specified by Landlord:



(A) that this Lease is unmodified and in full force and effect (or, if there has been modification, that the Lease is in full force and effect as modified
and stating the modifications) and that both the Landlord and the Tenant are not then in default under this Lease (or, if there has been a default, stating the default(s), if any);



(B) whether or not there are then existing any setoffs or defenses against the enforcement of any of the agreements, terms,
covenants or conditions hereof upon the part of Tenant to be performed or complied with (and, if so, specifying the same); and

Demised Premises are located.



In the event that Tenant fails
to deliver to Landlord the aforesaid certificate within the time period described hereinabove, then Tenant herein unconditionally agrees that it shall be liable on demand to pay Landlord the sum of $1,000.00 for each day that Tenant is late in
delivering the aforesaid certificate to Landlord, such sum to be as and for Landlords full and complete liquidated and agreed monetary damages suffered by reason of Tenants failure to timely deliver an estoppel certificate to Landlord.
In addition to the foregoing, in the event that Tenant fails to deliver to Landlord the aforesaid certificate within the time-period described hereinabove, then Tenant shall be deemed to have unconditionally waived (and shall be estopped from
raising) any and all alleged defenses or alleged Lease defaults allegedly committed by Landlord which it may have otherwise claimed or maintained in such estoppel certificate and Tenant shall also be deemed to have unconditionally assented to and
affirmed any and all provisions set forth in the estoppel certificate as same may have been prepared by the Landlord. In addition to the foregoing, Landlord reserves



15



---

the right to exercise any further rights or remedies available to it under the Lease, at law or equity by reason of Tenants default hereunder.



49. LIMITATION OF LANDLORDS LIABILITY/EXCULPATORY CLAUSE: If
Landlord shall be an individual, joint venture, limited liability company, tenancy-in-common, co-partnership, partnership, limited partnership, unincorporated association, or other unincorporated aggregate of individuals and/or entities, or a
corporation, Tenant shall look only to such Landlords estate and property in the Building, for the satisfaction of Tenants remedies for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord
in the event of any default by Landlord hereunder, and no other property or assets of such Landlord (or of any partner, shareholder, member, individual, officer, director, agent or other owner or representative thereof, whether disclosed or
undisclosed) shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenants remedies under or with respect to this Lease, the relationship of Landlord and Tenant hereunder or Tenants use or occupancy
of the Demised Premises.



50. BROKER: Tenant covenants, warrants and
represents that there was no broker instrumental in consummating this lease other than Cushman & Wakefield, Inc. and Julien J. Studley, Inc. (collectively, the Broker), and no conversations or negotiations were had with any other
broker concerning the renting of the Demised Premises. Tenant and Landlord agree to indemnify, defend and hold and save the other harmless against any and all liability from any claims of any broker (other than the Broker) who claims to have dealt
with the other party (including, without limitation, the cost of counsel fees in connection with the defense of any such claims in connection with the renting of the Demised Premises).



51. CONFLICT OF TERMS: In the event any term, covenant, condition or agreement contained in this rider to the Lease shall conflict or
be inconsistent with any term, covenant, condition or agreement contained in the printed portion of this Lease, then the parties agree that the rider provision shall prevail.



52. TENANTS REMEDIES: With respect to any provision of this Lease which provides, in effect, that Landlord shall not
unreasonably withhold or unreasonably delay any consent or any approval, Tenant in no event, shall be entitled to make, nor shall Tenant make, any claim, and Tenant hereby waives any claim, for money damages; nor shall Tenant claim any money damages
by way of setoff, counterclaim or defense, based upon any claim or assertion by Tenant that Landlord has unreasonably withheld or unreasonably delayed any consent or approval; but Tenants sole remedy shall be an action or proceeding to enforce
any such provision, or for specific performance, injunction or declaratory judgment.



53. NO EXCESSIVE NOISE: Tenant agrees that it will use the Demised Premises and will perform all work required or permitted hereunder in such a manner so as not to create any excessive noise which disturbs any of the other tenants of
the Building or persons occupying adjacent and neighboring premises.



54.
LABOR REGULATIONS: Tenant covenants and agrees that prior to and throughout the demised term, it shall not take any action which would violate Landlords union contract, if any, affecting the Building, nor create any work stoppage,
picketing, labor disruption or dispute, or any interference with the business of the Landlord or any other tenant or occupant in the Building or with the rights and privileges of any person(s) lawfully in said Building, nor cause any impairment or
reduction of the good name of the Building. Any default by Tenant under this Article shall be deemed a material default entitling Landlord to exercise any or all of the remedies as provided in this Lease.



55. CONTROL OF TENANT: If the Tenant is a corporation (other than one whose shares are
regularly and publicly traded on a recognized stock exchange), partnership or other entity other than an individual, Tenant represents that the ownership and power to vote the majority of its entire outstanding capital stock or other controlling
interest (collectively Controlling Interest) belongs to and is vested in the person(s) executing this Lease or members of his or their immediate family.



56. ADDENDUM TO ARTICLE 22: If Tenant shall default in surrendering the Demised Premises upon the expiration or termination of the
term, Tenants occupancy subsequent to such expiration



16



---

or termination, whether or not with the consent or acquiescence of Landlord, shall be deemed to be that of a tenancy at will and in no event from
month-to-month or from year-to-year, and it shall be subject to all the terms, covenants and conditions of this lease applicable thereto, except the Minimum Rent and Additional Rent shall be the greater of (i) two hundred percent of (or 200% of) the
amount payable in the last year of the term and (ii) the then fair market value minium rental and additional rental which would be payable with respect to the Demised Premises, and no extension or renewal of this Lease shall be deemed to have
occurred by such holding over.



57. ADDENDUM TO ARTICLE 18:



(A) Should Tenant fail to pay within five (5) days of when due any
installments of Minimum Rent, Additional Rent, or any other sum payable to Landlord under the terms of this Lease, then a late charge in the amount of $0.10 per $1.00 due shall be added to the sum due and shall be deemed Additional Rent hereunder.
If Tenant shall issue a check to Landlord which is returnable unpaid for any reason, Tenant shall pay Landlord an additional charge of $100.00 for Landlords expenses in connection therewith. If Tenant shall default (i) in the timely (5 days)
payment of Fixed Rent or Additional Rent for any two (2) consecutive months or for a total of three (3) months in any period of twelve (12) months then, notwithstanding, that such defaults shall have each been cured within the applicable period, if
any, any further similar default shall be deemed to be deliberate and Landlord thereafter may serve Tenant with a three (3) days notice of termination without affording to Tenant an opportunity to cure such further default at which time the
term of this Lease shall terminate as if that day were the Expiration Date.



(B) Notwithstanding anything in this Lease to the contrary, to the fullest extent permitted by law, and as a material inducement to Landlord to execute this Lease, Tenant hereby specifically waives the right, during
the term of this Leaseor during the pendency of any litigation arising out of this Lease, to stay, attempt to stay
or otherwise toll the period of termination described in Articles 17 or 18 of the Lease, and Tenant hereby also waives the right to make application to any Court or authority for such a stay (such as a Yellowstone Injunction) during the
pendency of any litigation arising out of this Lease, and any stay, attempt to stay or application to any Court for such a stay shall itself be considered a material breach of this Lease, thereby entitling Landlord to all of its remedies hereunder.



58. ENTIRE AGREEMENT: No earlier statement or prior written matter
shall have any force or effect. Tenant agrees that it is not relying on any representations or agreements other than those contained in this Lease. This agreement shall not be modified or canceled except by writing subscribed by all parties.



59. SAVING PROVISION: If any provision of this Lease, or its
application to any situation shall be invalid or unenforceable to any extent, the remainder of this Lease, or the application thereof to situations other than that as to which it is invalid or unenforceable, shall not be affected thereby, and every
provision of this Lease shall be valid and enforceable to the fullest extent permitted by law.



60. LEASE NOT BINDING UNLESS EXECUTED: Submission by Landlord of the within Lease for execution by Tenant shall confer no rights nor impose any obligations on either party unless and until both Landlord and
Tenant shall have executed this Lease and duplicate originals thereof shall have been delivered to the respective parties.



61. AIRCONDITIONING UNIT: OVERTIME SERVICES:



(A) Landlord shall deliver the Demised Premises to Tenant on the Commencement Date with a functioning heating, ventilation and air-conditioning air-cooled
package unit (Unit) which shall service the Demised Premises for normal office use. From and after the Commencement Date, Tenant shall at its sole cost and expense be responsible for the repair, maintenance and replacement of said Unit.
Notwithstanding the foregoing, if the Units compressor or any major structural component of the Unit falls into disrepair through no fault or negligence of the Tenant or any of its agents, employees or invitees, the Landlord shall repair
and/or replace same at its option at its sole cost and expense. Landlord may at its option install a time clock and/or meter to measure Tenants usage and time of operation of the Unit and readings of same may determine whether or not



17



---

Landlord shall elect to survey Tenants electrical usage in accordance with the provisions of Article 41 of this Lease.



(B) There shall be no charge to Tenant for the furnishing of any necessary
Building engineering services to the Demised Premises from 8:00 a.m. to 6:00 p.m. Mondays through Fridays, holidays excepted and for the furnishing of freight elevator facilities to the Demised Premises from 8:00 a.m. to 4:30 p.m. Mondays through
Fridays, holidays excepted. However, the Minimum Rent does not reflect or include any charge to Tenant for the furnishing of any such freight elevator facilities or Building engineering services during any other periods (Overtime
Periods). Tenant hereby acknowledges that Overtime Period freight elevator service may only be obtained by Tenant on weekend days for a minimum of four (4) hours of continuous usage (and Tenant shall be credited with same whether or not it
actually uses same). The Tenants move-in to the Demised Premises must be scheduled so as to occur after normal business hours (i.e., after 6:00 P.M. on normal workdays, and on weekends). Accordingly, if Landlord furnishes any such freight
elevator facilities or Building engineering services at the request of Tenant during Overtime Periods, Tenant shall pay Landlord Additional Rent for such services at the standard rates then fixed by Landlord for the Building or if no such rates are
then fixed at comparable rates then being charged by first-class office buildings in the midtown Manhattan vicinity. Landlords current rate for freight elevator service during Overtime Periods is $_______ per hour and the Landlords
current rate for Building engineers service during Overtime Periods is $______ per hour, provided, however, that Tenant acknowledges that such rates may change in the Building as Landlord determines in its sole discretion. Landlord shall not
be required to furnish any such services during any Overtime Periods unless Tenant shall notify Landlord in writing of its requirement for services prior to 12:00 p.m. of the day before which such services are requested or by 12:00 p.m. of the last
preceding Business Day if such Overtime Periods are to occur on a day other than a Business Day. If Tenant fails to give Landlord such advance notice, then failure by Landlord to furnish or distribute any such services during such Overtime Periods
shall not constitute an actual or constructive eviction, in whole or in part, or entitle Tenant to any abatement or diminution of rental, or relieve Tenant from any of its obligations under this Lease, or impose any liability upon Landlord or its
agents by reason of inconvenience or annoyance to Tenant, or injury to or interruption of Tenants business or otherwise. For purposes of this Lease, Business Day shall mean any day, excluding Saturdays, Sundays and all days
observed as holidays by the State of New York, the federal government or the labor unions servicing the Building.



62. WAIVER OF JURY TRIAL AND RIGHT TO COUNTERCLAIM. Tenant hereby waives all right to trial by jury in any summary or other action, proceeding or counterclaim
arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, the Demised Premises and the use and occupancy thereof, any claim of injury or damages, and any emergency statutory or other statutory remedy. Tenant
also hereby waives all right to assert or interpose a counterclaim in any summary proceeding or other action or proceeding to recover or obtain possession of the Demised Premises unless such waiver would result in Tenants loss of the right to
bring such claim in a separate proceeding.



63. INJUNCTIVE RELIEF: In
the event of a breach or threatened breach by Tenant of any of the covenants or provisions of this Lease, Landlord 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 Landlord from any other remedy, at 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s being evicted or dispossessed, or in the event of Landlords obtaining possession of the Demised Premises by reason of Tenants violation of the provisions of this Lease.
Tenant further agrees that it shall not interpose any noncompulsory counterclaim or noncompulsory counterclaims in a summary proceeding or in any other action or proceeding to evict the Tenant or otherwise recover possession of the Demised Premises
and Tenant hereby waives the right to interpose any noncompulsory counterclaim or noncompulsory counterclaims in any such proceeding(s).



64. RECORDATION: Tenant covenants not to place this Lease on record or to record this Lease without the prior written consent of Landlord. At the request of
Landlord, Tenant will execute a memorandum of lease for recording purposes containing references to such provisions of this Lease as Landlord, in its sole discretion, shall deem necessary.

65. ATTORNEYS FEES: Tenant agrees to pay Landlord upon demand, as an Additional Rental, a sum equal to all
costs and expenses (including attorneys fees, costs of investigation and disbursements) incurred by Landlord in enforcing any or all of its rights hereunder, specifically including the cost of collecting sums due, whether or not an action or
proceeding is commenced, or levying and collecting on any judgment or arbitration award in Landlords favor.



66. FORCE MAJEURE: In the event that either party hereto shall be delayed or hindered in or prevented from the performance or any act required hereunder other than
Tenants obligation to pay rent by reason of strikes, lockouts, labor troubles, failure of power, riots, insurrection, war or other reason of like nature not the fault of the party delayed in performing work or doing acts, such party shall be
excused for the period of delay. The period of performance of any such act shall then be extended for the period of such delay.



67. ELECTRICITY AND HEAT: Landlord shall not in arty way be liable or responsible to Tenant for any loss or damage or expense which Tenant may sustain or incur if
either the quantity or character of electric service, gas service or other utility is changed or is no longer available or suitable for Tenants requirements. Tenants use of electric current or other utilities in the Demised Premises
shall not at any time exceed the capacity of any of the electrical conductors, facilities and other systems in or otherwise serving the Demised Premises.



68. SECURITY.



(A)(i) Tenant has deposited with Landlord the sum of $329,595.00 upon the execution of this Lease, as security for the performance by Tenant of all of the
terms, covenants and conditions of this Lease on Tenants part to be performed. Landlord shall have the right, without notice to Tenant, and regardless of the exercise of any other remedy Landlord may have by reason of a default, to apply any
part of said deposit to cure any default of Tenant, and, if Landlord does so, Tenant shall upon demand deposit with Landlord the amount so applied so that Landlord shall have the full amount of the security ($329,595.00) at all times during the term
of this Lease. If Tenant shall fail to make such deposit, Landlord shall have the same remedies for such failure as Landlord has for a default in the payment of Minimum Rent. In the event of an assignment or transfer of the leasehold estate under
the Lease, (a) Landlord shall have the right to transfer the security to the assignee, (b) Landlord shall thereupon be automatically released by Tenant from all liability for the return of such security, and (c) Tenant shall look solely to the
assignee for the return of said security, and the foregoing provisions of this sentence shall apply to every transfer made of the security to a new assignee of Landlords interest in the Lease. The security deposited under this Lease shall not
be assigned or encumbered by Tenant without the prior consent of Landlord, and any such assignment or encumbrance shall be void. Landlord and Tenant acknowledge and agree that Tenant hereby waives any right, whether statutory or otherwise, to any
interest earned on any security deposited by Tenant hereunder, and Tenant shall in no event be entitled to interest on said security.



(ii) On or about the third (3rd) year anniversary of the Rent Commencement Date, provided that (a) this Lease remains in full force and effect and (b) the original Tenant named herein remains in possession of the Demised Premises and has not ever been
(nor is it then) in default under this Lease after the expiration of any grace or cure period expressly provided for in this Lease, the Landlord acknowledges that upon Tenants written request thereto it shall return to Tenant a portion of the
cash security deposit held by Landlord in the amount of $82,398.75. If the security was delivered in the form of cash, then Landlord shall either at its option remit a check to Tenant for this sum within 30 days of Tenants written request to
Landlord if same is due pursuant to the provisions of this Article or Landlord may elect to remit same to Tenant in the form of additional abated Minimum Rent under the Lease.



(iii) On or about the fifth (5th) year anniversary of the Rent Commencement Date, provided that (a) this
Lease remains in full force and effect and (b) the original Tenant named herein remains in possession of the Demised Premises and has not ever been (nor is it then) in default under this Lease after the expiration of any grace or cure period
expressly provided for in this Lease, the Landlord acknowledges that upon Tenants written request thereto it shall return to Tenant a portion of the cash security deposit held by Landlord in the amount of $82,398.75. If the security was
delivered in the form of cash, then Landlord shall either at its option remit a check to Tenant for this



19



---

sum within 30 days of Tenants written request to Landlord if same is due pursuant to the provisions of this Article or Landlord may elect to remit same
to Tenant in the form of additional abated Minimum Rent under the Lease.



(iv) The parties agree that notwithstanding any reduction in or return of security mandated by subparagraphs (A)(ii) and (iii) hereinabove the security deposit held by Landlord under the Lease shall never fall below
$164,797.50 at any time during the term of the Lease.



(v) In the event that a Letter of Credit has been delivered by Tenant to Landlord pursuant to subparagraph (B) hereinbelow, any reduction in or return of security mandated by subparagraphs (A)(ii) and (iii) hereinabove may be implemented by
Tenant delivering to the Landlord on each date a reduction in the security is mandated by the provisions of this Article a replacement Letter of Credit in the reduced amount indicated in subparagraphs (A)(ii) and (iii) hereinabove provided such
replacement Letter of Credit is acceptable to the Landlord in its sole discretion.



(B) (i) In lieu of a cash security deposit, Tenant may on no later than the date of this Lease as hereinabove set forth elect to deliver the security deposit required hereunder by delivering to Landlord a clean,
automatically self renewing, non-expiring, unconditional irrevocable standby letter of credit in the original amount of $329,595.00 (the Letter of Credit) issued to Landlord by a New York-based federally-insured lending institution
acceptable to Landlord. Said Letter of Credit must conform exactly to the form of Letter of Credit annexed hereto as Exhibit E and must otherwise be in form and content satisfactory to Landlord in its sole and absolute discretion. The
Letter of Credit shall unequivocally state on its face that it shall be effective and in place for a term no less than one hundred twenty (120) days after the last day of the entire term of this Lease. In the event that for any reason whatsoever the
Letter of Credit shall expire or shall fail to be renewed or replaced within 90 days prior to its expiration or renewal date, then Tenant herein unconditionally acknowledges that (i) Landlord shall have the unconditional right at any time to draw
upon the existing Letter of Credit and to hold such sums for the balance of the Lease term as cash security for Tenants performance under this Lease and (ii) at Landlords option, such failure shall be deemed to be a material default by
Tenant under this Lease and Landlord shall have all of its remedies thereof under the Lease, at law and at equity. Tenant shall ensure that the foregoing sentence shall appear in bold on the face of the letter of credit.



(ii) In the event Tenant shall default during the period in
which the Letter of Credit shall be in place after the expiration of any applicable grace periods expressly stated in this Lease, Landlord shall have the right at its sole option, and regardless of the exercise of any other remedy Landlord may have
by reason of a default, to immediately, draw against the Letter of Credit for the full amount of said Letter of Credit or to the extent necessary to cure the amount of any default and to apply any part of said Letter of Credit to the extent
necessary to cure any default of Tenant, and, if Landlord does so, Tenant shall upon demand issue a new Letter of Credit in favor of Landlord in the face amount of the original amount so drawn down so that Landlord shall at all times have the full
amount of the Letter of Credit required under this Article during the entire term of this Lease. If Tenant shall fail to issue such new Letter of Credit, Landlord shall have the same remedies for such failure as Landlord has for a default in the
payment of Minimum Rent. Landlords right to draw on the Letter of Credit shall continue for so long as Tenant shall remain in default. Tenant acknowledges that the Letter of Credit must state on its face that it shall be in place and effective
for a term of at least 120 days subsequent to the Expiration Date of the Lease.



(iii) In the event of an assignment or transfer by the Landlord of the leasehold estate under the Lease, (a) Landlord shall have the right
without any charge, cost, fee or expense charged to any party, to transfer or assign the Letter of Credit one or more times to any transferee or assignee by delivering to said transferee or assignee a blanket assignment of said Letter of Credit
(using a form acceptable to Landlord in its sole discretion), (b) Landlord shall thereupon upon such transfer be automatically released by Tenant from all liability, if any, for the return of such Letter of Credit, and (c) Tenant shall look solely
to the transferee or assignee for the return of said Letter of Credit, and the foregoing provisions of this sentence shall apply to every transfer or assignment made of the Letter of Credit to a new transferee or assignee of Landlords interest
in the Lease. The Letter of Credit issued under this Lease shall not be assigned or encumbered by Tenant or by the issuing bank without the prior consent of Landlord, and any such assignment or encumbrance shall be void.



20



---

(iv) The Letter of Credit may not be automatically self-reducing on its face, but may be
replaced with a new Letter of Credit in a reduced amount on the appropriate date by Tenant to comply with the express provisions of subparagraphs (A)(ii) and (iii) hereinabove provided such replacement Letter of Credit is acceptable to the Landlord
in its sole discretion.



69. NO CLEANING SERVICES BEING PROVIDED BY
LANDLORD:



(i) Landlord is not providing
Tenant with any cleaning services for the Demised Premises and said services are not included in any of the rental to be paid by Tenant under this Lease.



(ii) Tenant, at Tenants expense, shall cause all portions of the Demised Premises to be cleaned daily in a manner satisfactory to
Landlord, and to be regularly exterminated against infestation by vermin, roaches or rodents regularly and, in addition, whenever there shall be evidence of any infestation, and shall cause Tenants refuse and rubbish to be removed from the
Demised Premises and the Building.



(iii) Only
one or more persons firms or corporations authorized in writing by Landlord shall be permitted to act as maintenance contractor or as a cleaning service for any waxing, polishing, cleaning and maintenance work in the Demised Premises. Nothing herein
contained shall prohibit Tenant from performing such work for itself by use of its regular daily salaried employees. Landlord may fix, in its absolute discretion, at any time and from time to time, the hours during which and regulations under which
such services are to be furnished. Landlord expressly reserves the right to act as or to designate, at any time and from time to time, an exclusive contractor for all or any one or more of such services, provided that the quality thereof and the
charges therefor are reasonably comparable to that of other contractors, and Landlord, under such circumstances, expressly reserves the right to exclude from the Building any person, firm or corporation attempting to furnish any of such services.



70. SUBORDINATION AND ATTORNMENT:



(A) This Lease, and all rights of Tenant hereunder, are and shall be subject
and subordinate at all times to all 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. The provisions of 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 Landlord, the lessor under any such underlying lease (a Superior Lessor) or the mortgagee of any such mortgage (a Superior Mortgagee) 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) days after request therefor, Tenant hereby irrevocably constitutes and appoints Landlord as
Tenants attorney-in-fact, coupled with an interest, to execute, acknowledge and deliver any such instruments for and on behalf of Tenant.



(B) This Lease may not be surrendered, cancelled, modified or amended and the Superior Lessor and the Superior Mortgagee shall not be bound by any
previous prepayment of more than one months rent (including additional rent ) hereunder, unless such surrender, cancellation, modification, amendment or prepayment shall have been expressly approved in writing by the Superior Lessor or the
Superior Mortgagee, as the case may be and any such surrender, cancellation, modification, amendment of this Lease or prepayment not so approved shall be voidable by the Superior Lessor or the Superior Mortgagee, as the case may be.



(C) If any Superior Lessor or any Superior Mortgagee shall succeed to the
rights of Landlord under this Lease, whether through possession or foreclosure or delivery of a new lease or deed, then upon the request of such party so succeeding to Landlords rights (Successor Landlord), Tenant shall attorn to
and recognize such Successor Landlord as Tenants landlord under this Lease and shall promptly execute and deliver any instrument that such Successor Landlord may reasonably request to evidence such attornment. Upon such attornment this Lease
shall continue in full force and effect as a direct lease between Successor Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease except that Successor Landlord shall not: (i) be liable for any previous
act or omission of any prior landlord (including Landlord) under this Lease; (ii) be subject



21



---

to any offsets, credits or defenses which Tenant may be entitled to assert against any prior landlord (including Landlord); (iii) be liable for the return of
any security deposit, in whole or in part, to the extent that same is not paid over to Successor Landlord; or (iv) be bound by any previous surrender, cancellation, modification or amendment of this Lease or any previous prepayment of more than one
months rent (including additional rent) hereunder, unless such surrender, cancellation, modification, amendment or prepayment shall have been expressly approved in writing by the Superior Lessor or the Superior Mortgagee through or by reason
of which Successor Landlord shall have succeeded to the rights of Landlord under this Lease.



(D) All references in this Lease to mortgages shall be deemed to refer to and include a mortgage, deed of trust or deed to secure debt according to whichever is applicable in the state where the Demised
Premises are located, and all references to mortgagee shall be deemed to refer to the holder of a mortgage or the beneficiary/holder of a deed of trust or deed to secure debt as applicable.



71. BUILDING DIRECTORY/SIGNAGE: Tenant shall have the right to display the number of
individual names in the Buildings Lobby Directory in the same proportion that the rentable space of the Demised Premises bears to the aggregate rentable space of the entire Building. Tenant may utilize its own graphics in implementing signage
to be located at the entrance to the Demised Premises, subject to Landlords prior written approval as to aesthetics and location (and subject, also, to the compliance by Tenant with applicable law and with all of the provisions of this Lease
applicable thereto.)



72. BILLING BY LANDLORD: Any bill, invoice,
statement or other notice rendered by the Landlord or any other party to the Tenant and which is not disputed or objected to by the Tenant within 30 days of the rendition of such bill, invoice, statement or other notice shall be deemed to be
unconditionally approved and accepted by the Tenant. In the event that Landlord has been delayed in rendering or has failed to render any bill, invoice, statement or other notice to Tenant beyond the originally anticipated due date thereof, such
delay or failure shall not prejudice any of Landlords rights and no waiver of any rights of the Landlord shall have occurred or be deemed to have occurred as a result of any of Landlords delay or failure as described hereinabove.



73. ALL ADDITIONAL RENTAL PAYMENTS:



(A) Tenants obligation to make any Additional Rent payments under this
Lease, including, without limitation, the Additional Rental payments provided for in Articles 41, 42 and 43 of this Lease, shall be absolute and not conditioned on the happening of any act, thing or occurrence, including without limitation, the time
or timeliness at or with which such statement, bill or demand is furnished to or made upon Tenant. Landlords failure during the term of this Lease to prepare and deliver any statements or bills required to be delivered to Tenant hereunder, or
Landlords failure to make a demand under any Articles of this Lease shall not in any way be denied to be a waiver of, or cause Landlord to forfeit or surrender its rights to collect, any Additional Rent which may have become due pursuant to
any such Articles of this Lease during the term of this Lease. Tenants liability for the Additional Rent due under any Articles of this Lease shall continue unabated during the remainder of the term of this Lease and shall survive the
expiration or sooner termination of this Lease.



(B) In no
event shall any adjustment of any payments payable by Tenant in accordance with the provisions of any Articles of this Lease result in a decrease in Minimum Rent nor shall any adjustment of any Additional Rent payable by Tenant pursuant to any
provision of any Articles of this Lease result in a decrease in any other Additional Rent payable by Tenant pursuant to any other provisions of this Lease, it being agreed and understood that the payment of Additional Rent under any Articles of this
Lease is an obligation supplemental to Tenants obligations to pay Minimum Rent and any other Additional Rent pursuant to any other provision of this Lease.



(C) If a Tax Year or lease year shall end after the expiration or termination of the term of this Lease, the Additional Rent
payable by Tenant in respect thereof shall be prorated to correspond to that portion of such year occurring within the term of this Lease.



22



---

(D)   (i) Landlords failure to render any Tax bill or statement with respect to any Tax
Year shall not prejudice Landlords right to thereafter render a Tax bill or statement with respect thereto or with respect to any subsequent Tax Year, nor shall the rendering of a Tax bill or statement prejudice Landlords right to
thereafter render a corrected Tax bill or statement for that Tax Year, as the case may be. Nothing herein contained shall restrict Landlord from issuing a Tax bill or statement at any time there is an increase in Taxes during any Tax Year or any
time thereafter.



(ii) Each Tax bill or
statement shall be conclusive and binding upon Tenant unless (i) with respect to such Tax bill or statement, on or before thirty (30) days after the delivery by Landlord to Tenant of such statement, Tenant shall notify Landlord that it disputes the
correctness of such Tax bill or statement, specifying the particular respects in which such Tax bill or statement is claimed to be incorrect. Pending the determination of such dispute, tenant shall pay any disputed portion of the relevant Tax
Payment to the Landlord (as and when otherwise payable to the Landlord under the appropriate Article of this Lease) and Tenant shall pay any undisputed portion of the relevant Tax Payment in accordance with the applicable Tax bill or statement (and
Landlord shall refund or credit any overpayment by Tenant following the determination of such dispute).



74. INTEREST: If any sums of money or charges required to be paid by Tenant under this Lease, including but not limited to Minimum Rent and Additional Rent payable by Tenant hereunder, are not paid at the time
provided in the Lease, they shall nevertheless, if not paid when due, bear interest from the due date thereof to the date of payment at the highest rate allowed by law to be charged the Tenant.



75. LEGAL RENT RESTRICTIONS:



If any of the rents payable under the terms of this Lease shall be or become
uncollectible, reduced or required to be refunded because of any applicable law, ordinances, order, rule, requirement or regulation, Tenant shall enter into such agreement(s) and take such other steps (without additional expense to Tenant) as
Landlord may request and as may be legally permissible to permit Landlord 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, (a) the rents shall become and thereafter be payable in accordance with the amounts reserved herein for the periods following such termination and (b) Tenant
shall pay to Landlord, to the maximum extent legally permissible, an amount equal to (i) the rents which would have been paid pursuant to this Lease but for such legal rent restriction less (ii) the rents paid by Tenant during the period such legal
rent restriction was in effect.



76. SUBSTITUTE SPACE:



At any time prior to or during the term hereof, Landlord may substitute for
the Demised Premises, the Expansion Space (as such term is hereinafter defined) or any portion thereof (such premises being hereinafter referred to as the replaced premises) whether or not any other substitution has been made pursuant to
this Article prior to such time, other space in the Building (such other space being hereinafter referred to as the substitute premises) by a written notice given to Tenant not later than thirty (30) days prior to the date specified in
such notices as the effective date for such substitution. Such notice shall have annexed thereto a floor plan identifying the substitute premises on such plan. The substitute premises shall have substantially at least as much rentable area as the
replaced premises. If the effective date specified in such notice is subsequent to the Commencement Date, Tenant shall vacate the replaced premises and surrender the same to Landlord on or before such effective date provided Landlord, at its
expense, shall have substantially duplicated in the substitute premises Tenants initial work performed in the replaced premises. Landlord shall promptly after Tenant enters into occupancy of the substitute premises pay to Tenant any reasonable
moving costs incurred by Tenant because of such substitution. In the event of a substitution of space pursuant hereto, the term Demised Premises in this Lease shall thereafter and for all purposes be deemed to refer to the substitute
premises at such time.



77. CONDITIONAL LIMITATIONS:



In the event Tenant fails to pay any Minimum Rent or Additional Rent when
due, Landlord may, at its option, in addition to any other rights or remedies available to Landlord, send Tenant a ten (10)



23



---

day notice to cure such default. If Tenant fails to cure such default within such ten (10) day period, Landlord may terminate this Lease on five (5) days
notice to Tenant.



78. TENANTS LEASING OF THE REMAINING PORTION OF
RENTABLE SPACE LOCATED ON THE TWENTY THIRD FLOOR OF THE BUILDING:



(i) Commencing on the date (the Expansion Space Commencement Date) that vacant possession of the Expansion Space (hereafter defined) is delivered by Landlord to Tenant, and expiring on the Expiration Date of this Lease, Landlord
shall be deemed to have demised and let unto Tenant, in addition to the Demised Premises, and Tenant hereby shall be deemed to have leased and hired from Landlord, the remaining 7,078 rentable square feet of space located on the twenty third
(23rd) floor of the Building and the common corridor space appurtenant thereto (collectively, the Expansion
Space) as said space is shown on the Floor Plan of the twenty third (23rd) floor annexed hereto as Exhibit F and made a part hereof. Possession of said space shall be delivered to Tenant if, as, and when (after its leasing to a
third party or otherwise) it becomes vacant and available for leasing (in Landlords sole determination) during the term of this Lease and is not (or has not been) leased or committed to, and leasing rights therein have not been given or
committed to, any other party, including, without limitation, any other party now occupying or at any time occupying or leasing or proposing to lease the Expansion Space from Landlord. Unless otherwise amended as set forth in this Article, the terms
and conditions of this Lease shall apply to the Expansion Space in the same manner and fashion that they apply to the Demised Premises until the Expiration Date. Effective from and after the Expansion Space Commencement Date, the Expansion Space
shall be added to, and be deemed a part of, the Demised Premises and the Demised Premises, as referred to in the Lease, shall mean and refer collectively to the Demised Premises described in the Lease and the Expansion Space.



(ii) Landlord shall give written notice to the Tenant of the availability of
the Expansion Space for leasing by Tenant after Landlord learns of the date on which the Expansion Space shall become available for leasing to the Tenant in accordance with the provisions of subparagraph (i) hereinabove (Landlords
Notice). In the event the Expansion Space Commencement Date is to occur on or prior to July 1, 2002 then Landlords Notice shall be sent to Tenant at least ninety (90) days prior to the Expansion Space Commencement Date. The Annual
Minimum Rental Rate to be paid by Tenant for the Expansion Space shall be the then escalated per square foot Annual Minimum Rental Rate for the Demised Premises in effect on the date that the Landlords Notice is sent to Tenant. For example,
(a) if Landlords Notice is sent during the first 60 Lease Months of this Lease then the Annual Minimum Rental Rate payable by Tenant for the Expansion Space shall be $360,978.00 per Lease Year, or $30,081.50 per Lease Month (including
electricity, subject to Article 41 of the Lease, but excluding Additional Rent and escalations as provided in Articles 42, 43 and other provisions of this Lease) and (b) if Landlords Notice is sent during the last 63 Lease Months of this Lease
then the Annual Minimum Rental Rate payable by Tenant for the Expansion Space shall be $382,212.00 per Lease Year, or $31,851.00 per Lease Month (including electricity, subject to Article 41 of the Lease, but excluding Additional Rent and

Within ten (10) days of sending the Landlords Notice, Landlord shall deliver to Tenant a written amendment of this Lease for the Expansion Space containing the terms of the leasing by Tenant of the Expansion
Space, including, without limitation, the Annual Minimum Rental for the Expansion Space and the Additional Rent and escalations payable thereunder. Tenant shall execute and return seven (7) copies of said amendment of Lease to Landlord together with
the first monthss installment of Minimum Rent payable for the Expansion Space and the security deposit payable thereunder within five (5) days of receipt of a copy of the amendment of Lease from Landlord. All notices and documents to be given,
executed and/or delivered by Tenant hereunder shall be given by certified mail, return receipt requested and must be given within the time periods set forth in this Article, WITH TIME BEING OF THE ESSENCE.

covenants, agreements, provisions, terms and conditions as are contained in this Lease, except that (a) the Annual Minimum Rental Rate for the Expansion Space shall be as described in subparagraph (ii) hereinabove, (b) Tenant shall pay Additional

Year (or $ 1,769.50 per Lease Month), (e) the additional security deposit for the Expansion Space shall be twelve (12) months of the equivalent of the average Minimum Rental installment payable for the Expansion Space for the remaining Lease term,
(f) (i) Tenant shall receive three (3) months of free Minimum Rent for the Expansion Space if the Expansion Space Commencement Date is on or before August 1, 2001 or (ii) Tenant shall receive two (2) months of free Minimum Rent for the Expansion
Space if the Expansion Space Commencement Date is after August 1, 2001 and (g) Tenant shall receive a separate Landlords Contribution for the Expansion Space equivalent to $30.00 per rentable square foot of the Expansion Space, which sum shall
be prorated for the remainder of the Lease term. The term of any lease for the Expansion Space shall commence on the Expansion Space Commencement Date and shall expire concurrently with the expiration of the term of this Lease or until the term of
this Lease shall sooner cease and/or terminate as provided in this Lease. The Expansion Space shall be accepted by Tenant in its then as is condition and Landlord shall not be required to perform any work or furnish any materials or
allowance in order to prepare the Expansion Space for Tenants occupancy, and there shall be no abatement of rent payable under any lease (or amendment of this Lease) for the Expansion Space (except as may be otherwise expressly set forth
herein).



(iv) In the event Tenant fails for any reason
whatsoever to execute the amendment of Lease for the Expansion Space within five (5) days of receipt of a copy of the amendment of Lease from Landlord, TIME BEING OF THE ESSENCE, then, at Landlords option, Landlord may deem Tenants
leasing of the Expansion Space to be forever and unconditionally lapsed and nullified, and if such option is exercised by Landlord then Landlord shall have the right to lease (or not lease) the Expansion Space to any party free and clear of any
rights of the Tenant in and to the Expansion Space.



(v)
Landlord shall not be liable to Tenant for any failure of an existing tenant, subtenant, licensee or other occupant to vacate any portion of the Expansion Space upon the expiration of its lease term. The obligations of Landlord and Tenant under this
Article and under the provisions of any lease agreement (or lease amendment, at Landlords sole option) shall be suspended during the period of holding over and until Landlord can deliver legal possession of such space to Tenant. In the event
that a tenant, subtenant, licensee or other occupant fails to vacate or surrender its leased space, any rights that Tenant may have in and to such space shall be deemed extinguished without any liability on the part of Landlord therefor. Landlord
makes no representations or warranties as to the validity and/or enforceability of any provisions contained or to be contained in existing or future leases for the Expansion Space.



(vi) Notwithstanding anything to the contrary contained in this Article, Landlord has advised Tenant that (i) any current
occupant of the Expansion Space or any other party, whether or not a tenant of the Building (collectively, the Prior Optionees) may currently have or in the future may obtain certain rights to lease the Expansion Space, and (ii) the
existing tenant, if any (the Existing Tenant) in the Expansion Space may extend the terms of its lease either pursuant to an option or otherwise, and Landlord and Tenant agree that Tenants leasing of the Expansion Space under this
Article with respect to the Expansion Space is subject and subordinate to the rights of the Prior Optionees and the Existing Tenant, so that Landlord shall have no obligation to notify Tenant of the availability of the Expansion Space (and Tenant
shall have no rights with respect thereto) until after the Prior Optionees and Existing Tenants rights with respect to the Expansion Space shall have accrued and expired without having been exercised and the Expansion Space shall have
been vacated and surrendered to Landlord.
