NOW, THEREFORE, in consideration of the mutual covenants and conditions contained herein, Sublandlord and Subtenant covenant and agree as follows:

1.Premises. Sublandlord hereby subleases to Subtenant, and Subtenant hereby takes and hires from Sublandlord, the Premises, on and subject to the terms, covenants and conditions set forth in this Sublease.

If the Commencement Date is a day other than the first day of a calendar month, the Base Rent for the month in which the Commencement Date occurs will be prorated (based on the actual number of days in such month) and such prorated Base Rent shall be paid by Subtenant on or prior to the Commencement Date.

(e)     In the event of any casualty or condemnation affecting the Premises, Rent shall be proportionately or fully abated in accordance with the terms of the Master Lease. Further, in connection with any abatement right under the Master Lease, Rent shall be correspondingly and proportionately abated hereunder for as long as such abatement shall continue under the Master Lease.

5.Master Lease; Subordination.

(a)    This Sublease is and shall at all times remain subject and subordinate to all of the terms, covenants and conditions of the Master Lease, and Landlord shall have all rights in respect of the Master Lease and the Premises as set forth therein. Subject to the provisions of Section 6 hereof, except for (i) payments of Rental (as defined in the Master Lease) by Sublandlord to Landlord pursuant to the provisions of the Master Lease and (ii) Sublandlord’s obligation to maintain insurance (which does not negate Subtenant’s obligation to also maintain insurance), and (iii) any obligation inconsistent with the express terms of this Sublease, Subtenant hereby assumes and agrees to perform for Sublandlord’s benefit, during the term of this Sublease, all of Sublandlord’s obligations under the Master Lease with respect to the Premises that accrue during the Sublease Term (collectively, the “Assumed Obligations”).

6.Incorporation of Master Lease.

(a)Subject to the exclusions, limitations and modifications set forth in this Sublease, the terms, provisions, covenants and conditions of the Master Lease are incorporated in this Sublease by reference so that, except to the extent that they are excluded, limited or otherwise modified by the provisions of this Sublease for the purpose of incorporation by reference, each and every term, covenant and condition of the Master Lease binding on or inuring to the benefit of the landlord thereunder shall, in respect of this Sublease, bind or inure to the benefit of Sublandlord, and each and every term, covenant and condition of the Master Lease binding or inuring to the benefit of the tenant thereunder shall, in respect of this Sublease, bind or inure to the benefit of Subtenant, with the same force and effect as if such terms, covenants and conditions were completely set forth in this Sublease, and as if the words (i) “Landlord” and “Tenant,” or words of similar import, wherever the same appear in the Master Lease, were

construed to mean, respectively, “Sublandlord” and “Subtenant” in this Sublease, (ii) “Premises,” wherever the same appears in the Master Lease were construed to mean “Premises” in this Sublease, (iii) “Lease,” or words of similar import, wherever the same appear in the Master Lease, were construed to mean this “Sublease,” and (iv) the words “Escalation Rent,” or words of similar import, wherever the same appear in the Master Lease, were construed to mean the Additional Rent payable under Section 3 of this Sublease. Subtenant represents that it has examined, read and is thoroughly familiar with the unredacted terms, covenants and conditions of the Master Lease, and Subtenant accepts those terms, covenants and conditions and obligations thereof that have been incorporated herein.

(b)Subject to subsections (a) and (c) of this Section 6, the following sections of the Master Lease are not incorporated as a part of this Sublease and are expressly excluded herefrom:

(i)     any provision (w) that is inconsistent with another express provision contained in this Sublease, (x) that is inapplicable to the Premises (i.e., the 9th floor of the Master Leased Premises), (y) that relates to a period of time that is prior to or beyond the Sublease Term or (z) that is redacted from the copy of the Master Lease attached hereto; and

(ii)    The Reference Page (other than the terms “Permitted Use” and “Late Charge”), Sections 2.1, 2.2, 2.5, Article 3 (other than the payment obligations thereunder, subject to Section 3 above), Article 4 (other than the payment obligations thereunder, subject to Section 3 above), Section 6.5, Section 6.7, Article 10, Section 12.1(A) (other than the first two (2) sentences thereof), Section 12.5, Section 12.6, Article 13 (subject to Section 9 hereof), Article 14 (subject to Section 9 hereof), the penultimate sentence of Section 16.1(A), Sections 18.1(B), 28.1, 28.2 (provided that Sublandlord shall be required to use commercially reasonable efforts to cause Landlord to perform its obligations thereunder and Subtenant shall be obligated to pay for services utilized by Subtenant during Overtime Periods as set forth in such Section) and 28.3, Article 31, Article 35, Article 38, Sections 40.2, 40.10, and 40.19, Article 41, Article 42, Article 43, Article 44, Schedules A-1, A-2, A-4 and A-5, Schedule F, Schedule H, Schedule I, Schedule K, Schedule L, Schedule M and Schedule N.

(c)The following limitations shall apply to the interpretation and enforcement of the incorporated terms, covenants and conditions of the Master Lease:

(i)No provision of the Master Lease shall be deemed incorporated herein to the extent such provision is inconsistent with, conflicts with or cannot reasonably be interpreted together with any express provision of this Sublease.

(ii)Except as otherwise provided herein (including the first sentence of Section 8 hereof), the time limits contained in the Master Lease for the giving of notices, making of demands or performing of any act, condition or covenant on the part of the tenant thereunder (including the cure of any default), or for the exercise by the tenant thereunder of any right, remedy or option, are changed for the purposes of incorporation herein by reference by shortening the same in each instance by two (2) business days, so that in each instance Subtenant shall have two (2) business days less time to observe or perform or cure hereunder than Sublandlord has as the tenant under the Master Lease.

(iii)Any non-liability, release, indemnity or hold harmless provision, and any provisions pertaining to waiver of subrogation rights and or the naming of a party under an insurance policy, in the Master Lease for the benefit of Landlord that is incorporated herein by reference, shall be deemed to inure to the benefit of Sublandlord and Landlord, for the purpose of incorporation by reference in this Sublease.

(iv)Any obligation of Sublandlord that is contained in this Sublease by the incorporation by reference of the provisions of the Master Lease and not otherwise inconsistent with any express term of this Sublease shall be observed or performed by Sublandlord using commercially reasonable efforts to cause Landlord under the Master Lease to observe and/or perform the same upon notice from Subtenant. Subtenant shall not in any event have any rights in respect of the Premises greater than Sublandlord’s rights under the Master Lease, and notwithstanding any provision to the contrary, Sublandlord shall not be obligated to perform obligations that pertain to the Premises and common areas for which Landlord is obligated under the Master Lease or Subtenant is responsible under this Sublease, and are part of this Sublease by the incorporation by reference of provisions of the Master Lease, and Sublandlord shall have no liability to Subtenant for any such matter whatsoever, except that Sublandlord shall be obligated to use commercially reasonable efforts, upon request of Subtenant, to cause Landlord to observe and/or perform Landlord’s obligations under the Master Lease. Subject to the foregoing, Sublandlord grants to Subtenant, to the extent not expressly excluded by the terms of this Sublease, the right to receive all of the services available to the Premises that are to be provided by Landlord under the Master Lease (including, without limitation, with respect to access to the Premises, cleaning services, and freight elevator and loading dock usage, Sublandlord acknowledging that Subtenant shall have no liability to Sublandlord for charges for services provided to the Premises except to the extent imposed on Sublandlord pursuant to the Master Lease and provided that the same are required to be paid by Subtenant hereunder). Subtenant hereby expressly waives the provisions of any statute, ordinance or judicial decision, now or hereafter in effect, which would give Subtenant the right to make repairs at the expense of Sublandlord, or to claim any actual or constructive eviction by virtue of interruption in access or services to, or failure to make repairs in or to, the Premises or the Building.

(v)With respect to any approval or consent required to be obtained from Landlord under the Master Lease, such approval or consent must be obtained from both Landlord and Sublandlord (such consent not to be unreasonably withheld, conditioned or delayed by Sublandlord). Any approval or consent required of Sublandlord conclusively shall be deemed reasonably withheld if approval or consent also is required of Landlord, and Landlord withholds Landlord’s approval or consent.

(d)Subtenant shall fully perform all of the Assumed Obligations and shall indemnify, defend, protect, and hold harmless Sublandlord from any and all liability, damages, liabilities, claims proceedings, actions, demands and costs (including reasonable attorneys’ fees) resulting, directly or indirectly, from Subtenant’s failure to perform the Assumed Obligations.

(e)Without limiting the generality of the foregoing, for purposes of incorporating the terms, covenants and conditions of the Master Lease into this Sublease, the following provisions of the Master Lease are amended as follows:

(i)Subtenant shall protect, defend, indemnify and hold Sublandlord harmless from and against all liability as Sublandlord may incur to Landlord as a consequence of Subtenant’s failure to timely surrender possession of the Premises in the condition required by this Sublease, unless and to the extent the same is due to the act or omission of Sublandlord or its agents or employees.

(ii)Sublandlord shall only be required, after written request by Subtenant, to use commercially reasonable efforts to cause Landlord to perform any repairs or restoration or provide any services called for thereunder (including, without limitation, Landlord’s obligation to provide services pursuant to Article 28 of the Master Lease and Landlord’s obligation to make repairs pursuant to Article 7 of the Master Lease). For purposes

of this Sublease (including Section 6, Section 8 and Section 10 hereof), “commercially reasonable efforts” shall not include the pursuit of legal action by Sublandlord against Landlord.

(iii)Under Article 27 of the Master Lease, Sublandlord’s notice address shall be as provided adjacent to Sublandlord’s signature below, or at such other address as Sublandlord may from time to time designate in writing to Subtenant; and Subtenant’s notice address shall be as provided adjacent to Subtenant’s signature below. Any notice required or permitted under this Sublease shall be deemed to have been delivered upon actual receipt or upon refusal of delivery. Notices under this Sublease shall be permitted to be transmitted by overnight courier service, in addition to the other methods permitted under the Master Lease.

(iv)The rentable area of the Premises as specified in Recital A above is only an approximation and no variation between the amount so stated and the actual rentable area of the Premises shall alter the obligations of Sublandlord and Subtenant under this Sublease.

(v)All references in the Master Lease to any work to be performed by Landlord or Sublandlord for the initial delivery of the Premises to Subtenant shall be disregarded, as Subtenant has agreed to accept the Premises in the condition described in this Sublease. All references to the “Post-Commencement Work” in the Master Lease are deemed to be deleted.

(vi)Subtenant may not sublease all or any portion of the Premises or assign its interest in the Sublease without the prior written consent of both (i) Sublandlord (which shall be granted or withheld in accordance with the standards for Landlord’s consent in the Master Lease, except that Sublandlord shall have no recapture right), and (ii) Landlord (which consent may be withheld in its sole discretion, except to the extent otherwise set forth in Landlord’s Consent). In determining whether or not to grant consent, Subtenant shall provide (i) Sublandlord with such information regarding the proposed sublessee or assignee as Landlord is entitled to receive with respect to a proposed sublease or assignment under the Master Lease, and (ii) Landlord with such information as Landlord may require in its sole discretion (except to the extent otherwise set forth in Landlord’s Consent).

(f)Sublandlord covenants and agrees that (i) it will comply in all material respects with the terms of the Master Lease, except to the extent that such non-compliance is caused by the act or omission of Subtenant, (ii) it shall not at any time during the Sublease Term, unless otherwise agreed to by Subtenant in its reasonable discretion, enter into any amendments, modifications or other agreements with Landlord relating to the Master Lease that would adversely affect Subtenant’s occupancy or use of the Premises or would increase its obligations or reduce its rights hereunder and (iii) it shall not at any time during the Sublease Term, unless otherwise agreed to by Subtenant in its sole and absolute discretion, agree to any early termination of the Master Lease, including the exercise of Sublandlord’s rights under Section 44.3. of the Master Lease, if such termination would adversely affect Subtenant’s occupancy or use of the Premises or would increase its obligations or reduce its rights hereunder.

7.Brokerage. Except for Cushman & Wakefield, Inc. ( “Broker”), each party warrants and represents to the other that such party has not retained the services of any real estate broker, finder or any other person whose services would form the basis for any claim for any commission or fee in connection with this Sublease or the transactions contemplated hereby. Each party agrees to save, defend, indemnify and hold the other party free and harmless from any breach of its warranty and representation as set forth in the preceding sentence, including the other party’s reasonable attorneys’ fees and disbursements. Sublandlord shall pay all commissions due to Broker arising out of this Sublease pursuant to a separate written agreement.

8.Defaults. Notwithstanding the incorporation of Article 18 of the Master Lease herein, with respect to subsection 18.1(A) thereof, in the event any failure by Subtenant to pay Rental when due continues for more than three (3) business days after written notice from Sublandlord, an Event of Default shall have occurred and Sublandlord may take any and all actions permitted to be taken by Landlord under the Master Lease; provided, however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice if Tenant fails to pay Rent when due and, during the 12 month interval preceding such failure, Landlord has given Tenant written notice of failure to pay Rent on more than two (2) prior occasions. If Landlord shall fail to perform an obligation with respect to the Premises which Landlord is required by the Master Lease to perform and pursuant to such failure is in default under the Master Lease and such failure materially and adversely affects Subtenant’s occupancy or use of the Premises (any such failure, a “Landlord Default”), then upon written request of Subtenant, Sublandlord shall promptly make demand upon Landlord to remedy such Landlord Default. If Landlord does not remedy such default in a commercially reasonable time period (or such time period as may be required by the terms of the Master Lease), then Subtenant may make written request of Sublandlord to use, and Sublandlord shall use, commercially reasonable efforts to enforce any and all of Sublandlord’s right as Tenant under the Master Lease (provided, however, in no event shall Sublandlord be obligated to initiate litigation or any other adversarial proceeding against Landlord).

9.Early Termination of Master Lease. Where the Master Lease grants Sublandlord any discretionary right to terminate the Master Lease as to all or any portion of the Premises, whether due to casualty, condemnation, or otherwise, including, without limitation, pursuant to Section 44.3. of the Master Lease, Sublandlord shall not exercise any such right unless consented to by Subtenant in Subtenant’s sole and absolute discretion if such termination would adversely affect Subtenant’s occupancy or use of the Premises or would increase its obligations or reduce its rights hereunder. In connection with any casualty or condemnation affecting the Premises, Subtenant shall have the same rights to terminate this Sublease within the same time periods set forth under the Master Lease in Articles 13 and/or 14 of the Master Lease (except that for purposes of clause (iii) of Section 13.3(A) of the Master Lease, the word “Term” shall refer to the Sublease Term). Sublandlord shall promptly forward to Subtenant any communication from Landlord with respect to any damage or destruction or condemnation of the Premises. Landlord’s recognition of Subtenant as a direct tenant in the event of a termination of the Master Lease shall be governed by the terms of the Landlord’s Consent.

10.Consents Under Master Lease. If Subtenant desires to take any action which requires the consent of Landlord pursuant to the terms of the Master Lease, then (a) Subtenant shall not take any such action until it obtains the consent of Sublandlord (whose consent may not be unreasonably withheld, conditioned or delayed, except as otherwise set forth herein) and Landlord, and (b) Subtenant shall request that Sublandlord obtain Landlord’s consent on Subtenant’s behalf and Sublandlord shall use commercially reasonable efforts to obtain such Landlord’s consent, unless Landlord agrees that Subtenant may contact Landlord directly with respect to the specific action for which Landlord’s consent is required. Subtenant shall reimburse Sublandlord for all reasonable out-of-pocket costs actually incurred by Sublandlord in processing any request by Subtenant for Landlord’s or Sublandlord’s consent.

11.No Third Party Rights. Except as otherwise expressly provided herein, the benefit of the provisions of this Sublease is limited to Sublandlord and Subtenant and to their respective successors and permitted assigns. No third party shall be construed to have any rights as a third party beneficiary with respect to any of the provisions of this Sublease.

12.Landlord’s Consent to Sublease. This Sublease is subject to the consent of Landlord, which consent shall be evidenced on Landlord’s standard form (the “Landlord’s

Consent”). Sublandlord agrees to use commercially reasonable, good faith efforts to obtain the Landlord’s Consent as soon as reasonably possible following execution of this Sublease by Subtenant and Sublandlord. In the event that the Landlord’s Consent is not obtained by the date that is sixty (60) days after the date hereof, each of Sublandlord and Subtenant shall have the right to terminate this Sublease by providing written notice of termination to the other party. Sublandlord shall pay all administrative fees, costs and expenses charged by Landlord in connection with obtaining the Landlord’s Consent. In the event of any conflict between this Sublease and the Landlord’s Consent, the terms of the Landlord’s Consent shall control.

13.Counterparts. This Sublease may be executed in any number of counterparts, each of which counterparts shall be deemed to be an original, and all of which together shall constitute one and the same instrument.

14.Status of Lease. Sublandlord hereby represents and warrants to Subtenant that (i) a true, correct and complete copy of the Master Lease (other than certain redacted terms) is attached hereto as Exhibit A and has been executed and delivered by Landlord and Sublandlord and constitutes the entire agreement of the parties thereto relating to the lease of the Premises (other than such redacted terms), (ii) no default or breach by Sublandlord or, to Sublandlord’s knowledge, by Landlord, has occurred or presently exists under the Master Lease and (iii) subject to receipt of Landlord’s Consent, Sublandlord has the right and power to execute and deliver this Sublease and to perform its obligations hereunder.

15.Quiet Enjoyment. Sublandlord covenants and agrees with Subtenant that upon Subtenant paying the rent and additional rent reserved in this Sublease and observing and performing all of the other obligations, terms, covenants and conditions of this Sublease on Subtenant’s part to be observed and performed, Subtenant may peaceably and quietly enjoy the Premises during the term; provided, however, that this Sublease shall automatically terminate upon termination of the Master Lease and Subtenant shall have no claim against Sublandlord unless such termination was caused by the default of Sublandlord in the performance of its obligations under the Master Lease which have not been assumed by Subtenant hereunder or Sublandlord’s voluntary termination or modification of the Master Lease, including Sublandlord’s exercise of its right to terminate the Master Lease under Section 44.3 of the Master Lease, in violation of the terms of this Sublease.

16.Freight Elevator. Subtenant shall have the use of the freight elevators during regular Building hours pursuant to the terms of the Master Lease. Subtenant shall pay Landlord’s standard rates for overtime hours, if required, provided, however, Sublandlord shall pay any such overtime rates associated with Subtenant’s move-in, if Landlord requires overtime usage of the freight elevators in connection therewith.

17.Signage. Sublandlord shall use commercially reasonable efforts to have Landlord approve Subtenant’s signage in the Building lobby in the approximate location of Sublandlord’s existing signage, in the elevator lobby on the floor containing the Premises and on the entrance doors to the Premises, although Sublandlord shall have no liability if Landlord fails to approve such signage.

18.Limitation of Damages. Under no circumstances shall either party to this Sublease be liable for any indirect, incidental, special or consequential damages arising out of this Sublease, including, without limitation, any damages arising from lost revenues, profits, use or business opportunity, regardless of the cause of such damages and whether or not the other party was aware or should have been aware of the possibility of these damages; provided, however, that Subtenant will remain liable for any such damages as and to the extent

Sublandlord is liable for same under the Master Lease as a result of Subtenant’s breach or default hereunder with respect to the Premises.

19.Entire Agreement. This Sublease, the Landlord’s Consent and Exhibits A – G attached hereto contain all of the agreements of the parties with respect to the subject matter hereof, and there are no verbal or other agreements that modify or affect this Sublease. This Sublease and Exhibits A – G attached hereto supersede any and all prior agreements made or executed by or on behalf of the parties hereto regarding the Premises.

20.Terms and Headings. The words “Sublandlord” and” Subtenant” include the plural as well as the singular, and words used in any gender include all genders. The titles to sections of this Sublease are not a part of this Sublease and shall have no effect upon the construction or interpretation of any part hereof.

21.Severability. Any provision of this Sublease that shall prove to be invalid, void or illegal shall in no way affect, impair or invalidate any other provision hereof, and the remaining provisions hereof shall nevertheless remain in full force and effect.

22.Governing Law; Jurisdiction. This Sublease shall be governed by and construed in accordance with the laws of the state in which the Premises are located. The proper place of venue to enforce this Sublease is New York County, N.Y. In any legal proceeding regarding this Sublease, including enforcement of any judgments, each party irrevocably and unconditionally (i) submits to the jurisdiction of the courts of law in New York County, N.Y.; (ii) accepts the venue of such courts and waives and agrees not to plead any objection thereto; and (iii) agrees that service of process may be effected at the address specified for such party in this Sublease, or at such other address of which the other party has been properly notified in writing, and nothing herein will affect either party’s right to effect service of process in any other manner permitted by applicable law.

23.Sublandlord Representations. Sublandlord hereby represents to Subtenant, to Sublandlord’s actual knowledge:

(a)The building systems servicing the Premises are in good working order;

(b)The Premises is in compliance with (i) all applicable codes, laws and regulations, including, but not limited to the New York City building code, the local laws pertaining thereto, including fire and life-safety codes, and Title III of the Americans with Disabilities Act, and a Certificate of Occupancy, free and clear of outstanding construction liens and/or outstanding violations with the Department of Buildings, FDNY or the Fire Marshal that would delay Subtenant’s occupancy or construction (including permitting); and

(c)The Premises are in compliance with applicable laws governing the presence of hazardous materials and toxic mold.

24.Security Deposit. Subtenant has deposited with Sublandlord on the signing of this Sublease a security deposit in the amount of $513,760.00 (the “Security Deposit”) in the form of a letter of credit attached hereto as Exhibit F (the “Letter of Credit”) as security for the faithful performance and observance by Subtenant of the terms, provisions and conditions of this Sublease. Subtenant agrees that in the event of the occurrence of a default by Subtenant hereunder beyond the expiration of all applicable notice and cure periods, Sublandlord may draw so much of the Letter of Credit as is required to cure the default then occurring and use, apply or retain the such proceeds, to the extent required for the payment of any delinquent Rent, or any other sum as to which Subtenant is in default, or for any sum that Sublandlord is entitled to

expend by reason of the default (including any damages or deficiency accrued before or after summary proceedings or other re-entry by Sublandlord). In addition, Sublandlord may make multiple partial draws upon the Letter of Credit.
