 LOAN CANCELLATION AND RELEASE
AGREEMENT 
 This Loan Cancellation and Release Agreement (“Agreement”) is entered into
by and between The Telx Group, Inc. (hereinafter the “Company”) and Eric Shepcaro (hereinafter “Obligor”), as of this 2nd day of March, 2010 (the “Settlement Date”). 
 WHEREAS, the Obligor has incurred indebtedness (the “Indebtedness”) to the Company for principal and interest that are due
pursuant to one or more promissory notes that have resulted in the outstanding loan balance(s) set forth in the following summary: 
  

				
	 Original Issue Date
	  	Indebtedness as of
Settlement Date
	 July 8, 2007
	  	$	268,832.93

 WHEREAS, the
Company and the Obligor have mutually agreed to settle the Indebtedness through Obligor’s payment to the Company of fifty percent (50%) of the amount of the Indebtedness, with the Company cancelling and forgiving all remaining
Indebtedness, based on the mutual understanding between the Company and the Obligor that the Company may take such loan forgiveness of the Indebtedness into account when making future decisions regarding discretionary cash bonuses and stock awards
relating to the Obligor for his services in 2010; and 
 WHEREAS, the Obligor, in exchange for the cancellation of the
Indebtedness and all obligations under any associated promissory notes, is willing to pay the consideration set forth below, and to incur all tax liabilities associated with the forgiveness of the remaining Indebtedness on a date that the Company
selects in 2010; and the Obligor is willing to accept such consideration and to irrevocably waive any and all claims relating to the Indebtedness and any associated promissory notes. 
 NOW THEREFORE, the undersigned parties to this Agreement hereby mutually agree to all of the following: 
 1. Partial Repayment by the Obligor; Cancellation of Indebtedness. In consideration of the Company’s commitments herein, the
Obligor agrees to repay part of the Indebtedness through paying the Company one-hundred thirty-four thousand four hundred sixteen dollars and forty-six cents ($134,416.46) in immediately available funds within three (3) business days after the
Settlement Date. Provided that the Obligor makes such payment, then as of the Settlement Date, the Company shall irrevocably and

 
permanently surrender any and all of its rights to collect any Indebtedness, and acknowledges that any outstanding promissory notes relating to such Indebtedness shall be cancelled and no longer
valid effective on such Settlement Date. The Obligor recognizes and agrees that the Company may in its sole and absolute discretion take its cancellation of any unpaid Indebtedness into account when making future decisions regarding discretionary
cash bonuses and stock awards to be made to the Obligor with respect to his services for the Company in 2010. The Obligor further agrees that Section 5.2 of his Employment Agreement with the Company dated as of January 8, 2007 (the
“Employment Agreement”) is hereby amended, as follows: The Annual Bonus (as set forth in section 5.2) will not be (or be deemed) earned, vested, or payable to me until after it has been adjusted to reflect any unpaid
Indebtedness forgiven by the Company in accordance with this Agreement. The Obligor specifically agrees that this shall constitute a valid amendment to the Employment Agreement pursuant to Section 9.0 of that Employment
Agreement. Except as modified by this Agreement or otherwise in writing, all remaining provisions of the Employment Agreement shall remain in effect in accordance with their terms. 
 2. Complete Release by the Company. As of the Settlement Date, the Company irrevocably and unconditionally releases, acquits, and
forever discharges the Obligor, his heirs, assigns, and any successors to his interest, from any and all known or unknown claims, charges, promises, actions, or similar rights that the Company presently may have (“Claims”) relating
in any way to its rights to collect the Indebtedness. The Company understands that the Claims that it is releasing might arise under many different laws (including statutes, regulations, other administrative guidance, and common law doctrines), and
include without limitation claims such as breach of contract, implied contract, promissory estoppel, or claims under any federal, state or local statute, law, order or ordinance. 
 3. Tax Consequences. The Obligor agrees that the Company is to withhold all taxes it determines it is legally required to withhold as
a result of income that the Obligor will recognize from cancellation and forgiveness of the unpaid Indebtedness on the Settlement Date. The Obligor understands that he is obligated to pay any taxes, interest, or penalties that may be due or become
due with respect to such income under any applicable provision of federal, state or local law. The Obligor acknowledges that neither the Company nor any of its directors, officers, agents, or affiliates (together with the Company, the
“Company Released Parties”) have made any promise, representation or warranty, express or implied, regarding the tax consequences of any income that the Obligor may recognize pursuant to this Agreement. The Obligor further agrees
not to make any claim against the Company or any other person based on how the Company reports amounts of income arising under this Agreement to tax authorities or if an adverse determination is made as to the tax treatment of any amounts payable
under this Agreement. 

 4. No Other Inducements or Recourse. The Obligor acknowledges that no promise or
agreement not expressed in this Agreement has been made to the Obligor, and that Obligor shall have no claims or other recourse now or forever against the Company Released Parties with respect to this Agreement. 
 5. Binding Nature of Agreement. This Agreement shall be binding on the Obligor’s heirs, legal representatives, administrators,
executors, and assigns, and shall inure to the benefit of any successors and assigns of the Company Released Parties. 
 6.
Law Governing. This Agreement shall be governed by and construed under the laws of the STATE OF NEW YORK, REGARDLESS OF LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICT OF LAWS THEREOF. 
 7. Entire Agreement. This Agreement represents the entire agreement between the parties and has been entered into by Obligor with a
full understanding of its terms, with an opportunity to consult with counsel and without inducement or duress. This Agreement may not be changed orally, and any written change or amendment must be signed and accepted by the Company. If any provision
in this Agreement is found to be unenforceable, all other provisions will remain fully enforceable. This Agreement may be executed in counterparts, each of which shall be considered an original, but all of which together shall constitute one and the
same instrument. 
 WHEREFORE, the undersigned parties to this Loan Cancellation and Release Agreement have agreed to the
foregoing as of the Settlement Date.

CHELSEA COMMERCE LP, a Delaware limited partnership (“Landlord”) with an address c/o Taconic Investment Partners LLC, 111 Eighth Avenue, New York, New York 10011 and TELX - NEW YORK 111 8TH, LLC,
a Delaware limited liability company (“Tenant”) with an address at 111 Eighth Avenue, New York, New York 10011. 
 Statement of Facts 
 By Agreement of Lease dated as of March 15, 2007 (the
“Original Lease”), Landlord leased to Tenant and Tenant hired from Landlord portions of each of the eighth (8th) and fifteenth (15th) floors (collectively, the “Original Premises”) in the building located at 111 Eighth Avenue,
New York, New York 10011 (the “Building”) upon all of the terms, covenants, conditions and provisions more particularly described in the Original Lease. Pursuant to Section 10.7 of the Lease, Landlord granted to Tenant a
license to use an area of the roof setback above the seventh (7th) floor of the Building (the “Original Setback Area”), and pursuant to Section 10.10 of the Lease, Landlord granted to Tenant the right to use the Roof Space, in both cases upon all of the terms, covenants,
conditions and provisions more particularly described therein. 
 Pursuant to that certain First Amendment
of Lease dated as of July 3, 2008 (the “First Amendment”), Landlord leased to Tenant and Tenant hired from Landlord a portion of the third (3rd) floor of the Building (the “Expansion Space”) as more particularly described therein, upon all
of the terms, covenants, conditions and provisions more particularly described in the First Amendment. 
 Pursuant to that certain Second Amendment of Lease dated as of December 9, 2008 (the “Second Amendment”), Landlord leased to Tenant and Tenant hired from Landlord a portion of the fourteenth (14th) floor of the Building (the “Second Additional
Premises”), as more particularly described therein, upon all of the terms, covenants, conditions and provisions more particularly described in the Second Amendment. Pursuant to Section 4 of the Second Amendment, Landlord granted to
Tenant a license to use an area of the roof setback above the thirteenth (13th) floor of the Building (the “Second Setback Area”), upon all of the terms, covenants, conditions and provisions more particularly described therein. 
 The Original Lease, the First Amendment and the Second Amendment are collectively referred to as the “Lease,” and the
Original Premises, the Expansion Space and the Second Additional Premises are collectively referred to as the “Premises.” 
 Unless otherwise specifically indicated, all capitalized terms used herein shall have the meanings ascribed to them in the Lease. 

 Landlord and Tenant desire to add to the premises demised under the
Lease (i.e., the Premises) a portion of the fifth (5th) floor of the Building, containing 16,506 Rentable Square Feet, as shown in hatching on the plan annexed hereto as Exhibit A-1 (the “Third Additional Premises - Space A”) and a portion of the fifteenth
(15th) floor of the Building, containing 4,975 Rentable
Square Feet, as shown in hatching on the plan annexed hereto as Exhibit A-2 (the “Third Additional Premises - Space B”) , in both cases upon the terms and conditions hereinafter set forth, and to otherwise amend the
Lease upon the terms and conditions hereinafter set forth. Third Additional Premises - Space A and Third Additional Premises - Space B are sometimes collectively referred to herein as the “Third Additional Premises.” 
 NOW, THEREFORE, for and in consideration of the payments to be made hereunder by Tenant to Landlord and the mutual consideration
hereinafter set forth, the parties hereto agree as follows: 
 Terms 
  

	 	1.	THIRD ADDITIONAL PREMISES 

 (a) Effective as of the applicable Third Additional Premises Commencement Date (as hereinafter defined), and continuing thereafter up to and including the Third Additional Premises Expiration Date (as hereinafter defined), unless the term
of the Lease, as amended by this Third Amendment, is sooner terminated pursuant to the terms and conditions of the Lease, as amended by this Third Amendment, the applicable Third Additional Premises shall be added to the Premises, on all of the same
terms, covenants, conditions, and provisions of the Lease, except as otherwise expressly provided in this Third Amendment. 
 (b) For the purposes of this Third Amendment: 
 (i) “Third Additional Premises Commencement Date”
means, with respect to the Third Additional Premises - Space A and the Third Additional Premises - Space B, as the case may be, the date that Landlord delivers vacant possession of the applicable Third Additional Premises to Tenant (including,
with respect to the Third Additional Premises - Space A, the existing pre-action sprinkler system that services the Third Additional Premises - Space A) with the corresponding Landlord’s Work substantially completed; 
 (ii) “Landlord’s Work” means the work described in Exhibit B hereto, which by this reference is made a part hereof;

 (iii) The applicable Landlord’s Work shall be substantially completed when such Landlord’s Work has been completed
except for minor details of construction, decoration and mechanical adjustments, if any, the non-completion of which does not materially interfere with Tenant’s use of the corresponding Third Additional Premises, or which, in accordance with
good construction practice, should be completed after the completion of other work to be performed in the Third Additional Premises in question; 
  

 2 

 (iv) “Third Additional Premises - Space A Rent Commencement Date”
means the date which is five (5) months after the Third Additional Premises Commencement Date for the Third Additional Premises - Space A; 
 (v) “Third Additional Premises - Space B Rent Commencement Date” means the date which is five (5) months after the Third Additional Premises Commencement Date for the Third
Additional Premises - Space B; and 
 (vi) “Third Additional Premises Expiration Date”
means the last day of the calendar month preceding the calendar month in which occurs the fifteenth (15th) anniversary of the Third Additional Premises Rent Commencement Date for the Third Additional Premises - Space A.

 (c) Effective on the date hereof, (i) the term “this Lease” as used in the Lease, shall be deemed to refer to
the Lease, as amended by this Third Amendment, (ii) subject to the Third Additional Premises being added to the premises demised under the Lease effective on the applicable Third Additional Premises Commencement Date, the term
“Premises,” as such term is used in the Lease, shall mean the aggregate of the Original Premises, the Expansion Space, the Second Additional Premises and the Third Additional Premises, and (iii) the floor plans of the Original
Premises, the Expansion Space and the Second Additional Premises attached to the Lease shall be amended to include the floor plans of the Third Additional Premises attached hereto as Exhibits A-1 and A-2. 
 (d) Landlord shall not be subject to any liability for failure to deliver possession of any portion of the Third Additional Premises to
Tenant on any specific date and the validity of this Third Amendment shall not be impaired under such circumstances, nor shall the same be construed to extend the term of the Lease, except that the applicable Third Additional Premises Commencement
Date will not occur until possession of the such Third Additional Premises shall be delivered to Tenant. For purposes of this Section 1(d), the provisions hereof are intended to constitute “an express provision to the contrary”
within the meaning of Section 223-a of the New York Real Property Law or any successor Law, which shall be inapplicable hereto, and Tenant hereby waives any right to rescind this Third Amendment that Tenant might otherwise have thereunder based
upon Landlord’s failure to deliver any portion of the Third Additional Premises to Tenant. 
  

	 	2.	TERM 

 (a)
Landlord and Tenant acknowledge and agree that the Expiration Date for the Premises (excluding the Third Additional Premises) is February 28, 2022, and that, subject to the provisions of Section 2(b) below, the term of the Lease
shall end with respect to the Premises (excluding the Third Additional Premises), the Original Setback Area, the Roof Space and the Second Setback Area on February 28, 2022 (unless the term of the Lease, as amended by this Third Amendment, is
sooner terminated pursuant to the terms and conditions of the Lease, as amended by this Third Amendment) and that the term “Expiration Date,” as used in the Lease, as amended by this Third Amendment, shall mean the Third Additional
Premises Expiration Date solely with respect to the Third Additional Premises, so that from and after February 28, 2022 the only premises demised under the Lease, or which Tenant shall otherwise be entitled to use, shall be the Third Additional
Premises.

Tenant exercises the first Renewal Option pursuant to Article 31 of the Lease and the term of the Lease is renewed for the five (5) year period commencing on March 1, 2022 and ending on February 28, 2027 (i.e., the new Expiration
Date), the term of the Lease shall be deemed renewed for the entire Premises, including the Third Additional Premises, upon all of the terms, covenants and conditions of said Article 31 and the other applicable provisions of the Lease, as amended by
this Third Amendment, except that (i) through the Third Additional Premises Expiration Date, the Fixed Rent for the Third Additional Premises shall continue to be as set forth in Schedule 1 hereto, and the Base Taxes and Comparison Years for
the Third Additional Premises shall continue to be as set forth in Section 3(a) hereof, and (ii) from and after the date next succeeding the Third Additional Premises Expiration Date, through the end of the first Renewal Term (i.e.,

Rentable Square Foot basis, as the Fixed Rent for the 15th
Floor Premises, and the Base Taxes and Comparison Years for the Third Additional Premises shall be the same as for the balance of the Premises. Thereafter, the second Renewal Option, if exercised by Tenant, shall apply to the entire Premises,
including the Third Additional Premises, with the new Expiration Date being February 29, 2032. 
 (c)
For the purposes of clarification, (i) wherever in the Original Lease there is a distinction made with respect to the Renewal FMV for the 8th Floor Premises and the 15th Floor Premises, such distinction shall also apply to the Expansion Space, the Second Additional Premises, the Third
Additional Premises - Space A, and the Third Additional Premises - Space B, and (ii) during any Renewal Term, the license fee for the Original Setback Area shall remain [***] per annum ([***] per month), and the license fee for the Second
Setback Area shall continue to increase as provided in Section 4(d) of the Second Amendment. 
  

	 	3.	MODIFICATION OF THE LEASE

 (ii) The term “Premises Area” as set forth in Section 1.1 of the Lease shall be increased by 16,506 Rentable Square Feet with respect to the Third Additional Premises - Space A and
4,975 Rentable Square Feet with respect to the Third Additional Premises - Space B;

portions. 

  

 4 

 (iii) The term “Tenant’s Share” as set forth in Section 7.l(b)

 (iv) The term “Base Taxes” as set forth in Section 7.1(e) of the Lease with respect to the entire Third Additional Premises only shall mean an amount equal to fifty
(50%) percent of the sum of (A) the Taxes payable for the Tax Year commencing on July 1, 2009 and ending June 30, 2010, and (B) the Taxes payable for the Tax Year commencing on July 1, 2010 and ending June 30,
2011; 
 (v) The term “Comparison Year” as set forth in Section 7.1(f)(i) of the Lease with respect to
the entire Third Additional Premises only shall mean each and every Tax Year commencing with the 2010/2011 Tax Year; 
 (vi)
Section 10.1(b) of the Lease shall apply to the entire Premises, including the Third Additional Premises; 
 (vii) As
provided in Section 10.2 of the Lease, Landlord shall have no obligation to provide heat, ventilation or air-conditioning services to the Premises, including the Third Additional Premises. To the extent Tenant desires HVAC service to the Third
Additional Premises, Tenant may, in accordance with, and subject to, the applicable provisions of the Lease, as amended by this Third Amendment, service the Third Additional Premises with HVAC from the HVAC systems that service exclusively the other
portions of the Premises; 
 (viii) The following shall be added to the end of Section 10.5 of the Lease: “As part of
the Additional Premises Initial Alterations, Landlord approves, subject to Tenant’s compliance with all applicable provisions of the Lease and the Project Plan, Tenant’s installation of water-cooled supplemental air conditioning systems
and additional supplemental air conditioning units, from time to time (collectively, the “Supplemental Air System”) and located solely in the Third Additional Premises - Space A and the Third Additional Premises – Space B. Subject to
all applicable provisions of the Lease, Landlord agrees to reserve for Tenant’s use the chilled water necessary to operate the Supplemental Air System up to a total of one hundred (100) tons of air conditioning capacity. Tenant shall have
sixty (60) days from the last Third Additional Premises Commencement Date to notify Landlord that it intends to utilize such reserved chilled water. In the event Tenant effectively provides such notice to Landlord and Landlord accepts such
notice, Tenant agrees to pay Landlord a charge of $0.40 per ton per hour (“Chilled Water Charge”) for the usage of the chilled water. The Chilled Water Charge shall be paid monthly as part of Tenant’s monthly invoice and shall be
considered Additional Rent. Notwithstanding the foregoing or any of the other provisions of the Lease, Landlord shall have no liability to Tenant in the event that Landlord shall not have available for Tenant’s use any particular amount of
chilled water or in the event that any available chilled water does not meet the needs or specifications of the Supplemental Air System. In either of such events, Tenant’s only remedy shall be to notify Landlord that Tenant no longer desires
such chilled water, whereupon Landlord shall cease to deliver same to Tenant; provided, however, that Tenant shall remain liable for all chilled water delivered to Tenant prior to such notice to Landlord. 
  

 5 

 (ix) Section 10.9 of the Lease shall not apply to the Third Additional Premises. To
the extent Tenant desires emergency electric power service to the Third Additional Premises, Tenant may, in accordance with, and subject to, the applicable provisions of the Lease, as amended by this Third Amendment, service the Third Additional
Premises with emergency electric power from Tenant’s Generators; 
 (x) The area of space on the roof of the Building as
set forth on Exhibit D hereto shall be deemed included in the definition of Roof Space; and 
 (xi) The following shall be
added to the end of Section 14.6(f) of the Lease: “and further there shall not be more than one (1) subtenant of the Third Additional Premises - Space A and there shall not be more than one (1) subtenant of the Third Additional
Premises - Space B.”

(f) of the Lease, clause (ii) of Section 7.1(g) of the Lease, all references to “Operating Expense” in Article 7 of the Lease, and Exhibits A and C to the Lease shall not be applicable to the Third Additional Premises.

  

	 	4.	SECURITY DEPOSIT; GUARANTY 

 (a) Tenant has deposited with Landlord the sum of $1,879,587.50 as security for the full and faithful performance of all of the obligations of Tenant under the Lease, as amended by this Third Amendment
(all or any part of such amount, the “Security Deposit”), in the form of the Letter of Credit as set forth in subsection (b) below. If there occurs a default under any of the terms, covenants or conditions in the Lease,
as amended by this Third Amendment, on Tenant’s part to observe, perform or comply with (including, without limitation, the payment of any installment of Fixed Rent or any amount of Additional Rent), and, except in the case where the Term has
ended or in the case of any of the events described in Section 16.1(d) of the Lease, Tenant fails to cure such default after the giving of any required notice under the Lease of such default and the expiration of any applicable cure period or
if an Event of Default otherwise occurs, then Landlord may draw on the Letter of Credit (to the extent Landlord is not then holding the cash proceeds thereof after receiving a Non-Renewal Notice (as hereinafter defined)), and may use, apply or
retain all or any part of the cash proceeds of the Letter of Credit for the payment of any Fixed Rent or Additional Rent or any other sum in default, or for the payment of any other amount which Landlord may spend or become obligated to spend by
reason of such default or Event of Default, or to compensate Landlord for any other loss, cost or damage which Landlord may suffer by reason of such default or Event of Default. If Landlord uses, applies or retains all or any part of the cash
proceeds of the Letter of Credit, Tenant shall, within five (5) days after notice from Landlord, deposit with Landlord a letter of credit or an amendment to the original Letter of Credit in an amount sufficient to restore the Security Deposit
to the amount then required pursuant to the terms of this Section, i.e., $1,879,587.50, as such amount may be reduced pursuant to subsection (c) below. Tenant’s obligation to make such payment shall be deemed a requirement
that Tenant pay an item of Additional Rent, and Tenant’s failure to do so shall be a default under the Lease, as amended by

  

 6 

 
this Third Amendment. Any portion of the cash proceeds of the Letter of Credit not used, applied or retained by Landlord in satisfaction of the obligations of Tenant as to which a default or an
Event of Default shall have occurred shall be deposited by Landlord and retained as a cash security deposit. Landlord shall not, unless otherwise required under applicable Law, pay interest to Tenant on any cash proceeds of the Letter of Credit, and
if Landlord is required to maintain such proceeds in an interest bearing account, Landlord will retain the maximum amount permitted under applicable Laws as a bookkeeping and administrative charge. Tenant shall not assign or encumber any part of the
Security Deposit, and no assignment or encumbrance by Tenant of all of any part of the Security Deposit shall be binding upon Landlord, whether made prior to, during, or after the Term. Landlord shall not be required to exhaust its remedies against
Tenant or against the Security Deposit before having recourse to any other form of security held by Landlord (including any guarantees of Tenant’s obligations under the Lease, as amended by this Third Amendment), and recourse by Landlord to any
Security Deposit shall not affect any remedies of Landlord provided in the Lease, as amended by this Third Amendment, or available to Landlord under applicable Laws or available to Landlord under any such guarantees. So long as no default shall then
have occurred and be continuing, the Security Deposit or any balance thereof shall be returned to Tenant reasonably promptly after the expiration or sooner termination (other than a termination pursuant to Article 16) of the Term and Tenant’s
surrender to Landlord of the Premises in accordance with the applicable provisions of the Lease, as amended by this Third Amendment. 
 (b) Tenant shall deliver the Security Deposit to Landlord in the form of a clean, irrevocable, non-documentary and unconditional letter of credit (the “Letter of Credit”) issued by and drawn upon any commercial bank, trust
company, national banking association or savings and loan association having offices for banking and drawing purposes in the City of New York and which is a member of the Clearing House Association and is otherwise acceptable to Landlord (the
“Issuing Bank”) and which shall have outstanding unsecured, uninsured and unguaranteed indebtedness, or shall have issued a letter of credit or other credit facility that constitutes the primary security for any outstanding indebtedness
(which is otherwise uninsured and unguaranteed), that is then rated, without regard to qualification of such rating by symbols such as “+” or “-” or numerical notation, “Aa” or better by Moody’s Investors Service
and “AA” or better by Standard & Poor’s Corporation, and has combined capital, surplus and undivided profits of not less than $5,000,000,000.00. The Letter of Credit shall have a term of not less than one year, be in form and
content satisfactory to Landlord (and substantially as shown on Exhibit C to this Third Amendment), be for the account of Landlord, be in the amount of the Security Deposit then required to be deposited hereunder, and be fully transferable by
Landlord one or more times to successor owners of the Building or Landlord’s interest therein without the payment of any fees or charges, it being agreed that if any such fees or charges shall be imposed, then such fees or charges shall be paid
by Tenant and that the failure to pay such fees or charges shall not affect any such transfer. The Letter of Credit shall provide that it shall be deemed automatically renewed, without amendment, for consecutive periods of one year each thereafter
during the Term, unless the Issuing Bank sends notice (the “Non-Renewal Notice”) to Landlord by certified mail, return receipt requested, not less than sixty (60) days prior to the then expiration date of the Letter of Credit that the
Issuing bank elects not to have such Letter of Credit renewed. Additionally, the Letter of Credit shall provide that Landlord shall have the right, exercisable at any time after Landlord’s receipt of the

  

 7 

 
Non-Renewal Notice, by sight draft on the Issuing Bank, to receive the monies represented by the existing Letter of Credit. If Landlord draws upon the Letter of Credit solely as a result of a
Non-Renewal Notice, then Landlord shall hold such proceeds pursuant to the terms of this Section as a cash security deposit pending the replacement of the Letter of Credit. The failure of Tenant to replace any such cash security deposit with a
Letter of Credit that satisfies the requirements of this Section within ten (10) days after Landlord’s demand therefor shall be deemed a default by Tenant in the payment of Additional Rent, entitling Landlord to exercise any or all of its
rights and remedies. In the event of a sale or lease of Landlord’s interest in the Premises, within thirty (30) days of notice of such sale or leasing, Tenant, at Tenant’s expense, shall arrange for the transfer of the Letter of
Credit to the new landlord, as designated by Landlord, or have the Letter of Credit reissued in the name of the new landlord, and Landlord shall thereupon be released by Tenant from all liability for the return of the Letter of Credit; provided,
however, that if the Letter of Credit is reissued, Landlord shall return the original Letter of Credit issued in Landlord’s name to Tenant. 
 (c) (i) Prior to commencing any Third Additional Premises Initial Alterations (as defined in Section 5 below) in any portion of the Third Additional Premises, and during the progress of
same, Tenant shall deliver to Landlord a project plan for the Third Additional Premises Initial Alterations, which such project plan shall include total cost and payment structure information. The amount of the Security Deposit required to be
maintained pursuant to subsections (a) and (b) above shall be reduced, as more particularly provided in subsection (c)(ii) below, as and when portions of the Third Additional Premises Initial Alterations are completed and paid for,
provided, however, that if the Third Additional Premises Initial Alterations are to be performed in different portions of the Third Additional Premises at different times, then notwithstanding anything contained in this Section to the contrary,
Tenant shall not be entitled to any such reduction in the Security Deposit amount until the Third Additional Premises Initial Alterations have commenced in all portions of the Third Additional Premises, notwithstanding the fact that portions of the
Third Additional Premises Initial Alterations may have already been completed. 
 (ii) Provided that Tenant is not in default
in its obligation to pay any Fixed Rent or Additional Rent or to observe, perform or comply with any other term, covenant or condition in this Lease on Tenant’s part to observe, perform or comply with, and provided further that Landlord has not
used, applied or retained any portion of the Security Deposit pursuant to subsections (a) and (b) above, (A) the amount of the Security Deposit required to be maintained pursuant to subsections (a) and (b) above shall be
reduced by $626,529.16 promptly after Landlord’s receipt from Tenant’s Construction Manager of its certification that at least one-third (1/3) of all Third Additional Premises Initial Alterations in the entire Third Additional
Premises has been completed and paid for (which certification, to be effective, shall be accompanied by partial lien waivers, in recordable form, evidencing such payments); (B) the amount of the Security Deposit required to be maintained
pursuant to subsections (a) and (b) above shall be reduced by another $626,529.16 promptly after Landlord’s receipt from Tenant’s Construction Manager of its certification that at least two-thirds (2/3) of all Third
Additional Premises Initial Alterations in the entire Third Additional Premises has been completed and paid for (which certification, to be effective, shall be accompanied by partial lien waivers, in recordable form, evidencing such payments); and
(C)

  

 8 

 
Tenant shall no longer be obligated to maintain any Security Deposit pursuant to subsections (a) and (b) above promptly after Landlord’s receipt from Tenant’s Construction
Manager of its certification that all Third Additional Premises Initial Alterations in the entire Third Additional Premises has been completed and paid for (which certification, to be effective, shall be accompanied by full lien waivers, in
recordable form, evidencing such payments). Promptly after receipt by Landlord of the requisite certification and lien waivers from Tenant’s Construction Manager indicating that the portion of the Third Additional Premises Initial Alterations
in question has been completed and paid for, Landlord shall so notify Tenant, and, provided the conditions in the first sentence of this subsection (ii) remain satisfied, Landlord shall accept an amendment to the Letter of Credit then being
held by Landlord to effectuate such reduction. 
 (d) The Telx Group, Inc. (“Guarantor”), as guarantor of
Tenant’s obligations under the Lease pursuant to that Agreement and Guaranty dated as of March 15, 2007, as confirmed by Guarantor pursuant to the Consents of Guarantor attached to the First Amendment and Second Amendment, is executing and
delivering a Consent of Guarantor with respect to this Third Amendment, which Consent of Guarantor is attached hereto. Each year from and after the date hereof, within thirty (30) days after Guarantor’s annual audited financial statements
(each, a “Guarantor’s Annual Statement”) are prepared and certified, Tenant shall deliver a copy of each such Guarantor’s Annual Statement to Landlord. If, at any time, a Guarantor’s Annual Statement shows
Guarantor’s “Total Shareholder Equity” for the fiscal year covered by such Guarantor’s Annual Statement to be less than $70,000,000.00 or shows Guarantor’s “net cash provided by operating activities” for the fiscal
year covered by such Guarantor’s Annual Statement to be less than $10,000,000.00 (either of such events being herein referred to as a “Breach of Financial Covenant”), the Security Deposit amount required to be maintained by
Tenant pursuant to this Section (which amount, pursuant to subsection (c) above, may have theretofore been reduced to 0) shall be increased by an amount (the “Increased Security Deposit Amount”) equal to the aggregate annual
Fixed Rent payable by Tenant for the Third Additional Premises (as set forth in Schedule 1 hereto, without taking into account any abatements or reductions thereof) in effect as of the date Tenant delivers a copy of the Guarantor’s Annual
Statement in question, or, if Tenant fails to deliver a copy of a Guarantor’s Annual Statement, as of the date Landlord requests a copy of same. If Tenant fails to deliver a Guarantor’s Annual Statement to Tenant within such thirty
(30) day period, and such failure continues for more than ten (10) days after Landlord requests a copy of a Guarantor’s Annual Statement, it shall be conclusively presumed, for the purposes of increasing the amount of the Security
Deposit, that there was a Breach of Financial Covenant. Landlord’s failure to request a copy of a Guarantor’s Annual Statement(s) for any fiscal year shall not be deemed a waiver of Landlord’s right to request a Guarantor’s
Annual Statement for any subsequent fiscal year or a waiver of Tenant’s obligations under this subsection (d) and subsection (e) below. 
 (e) In furtherance of Tenant’s obligations under subsection (d) above, with the delivery of a Guarantor’s Annual Statement that shows a Breach of Financial Covenant or, if Tenant fails to
deliver a copy of a Guarantor’s Annual Statement within ten (10) days after Landlord requests a copy of same, Tenant shall deliver to Landlord an amendment to the Letter of Credit then being held by Landlord pursuant to this Section, which
increases the amount of such Letter of Credit by the Increased Security Deposit Amount. If Landlord is holding cash

  

 9 

 
proceeds of the Letter of Credit in lieu of the Letter of Credit itself, or, if pursuant to subsection (c) above, Landlord is no longer holding a Letter of Credit, then Tenant shall deliver
to Landlord within the applicable time period, a replacement Letter of Credit, in form and substance that satisfies in the requirements of this Section, either (at Landlord’s option) in the amount of the Increased Security Deposit Amount (in
which event Landlord shall continue to hold such cash proceeds, if any) or in the total amount of the Security Deposit required to be maintained by Tenant under this Section, including the Increased Security Deposit Amount (in which event, promptly
after Landlord’s receipt of the replacement Letter of Credit, Landlord shall return such cash proceeds, if any, to Tenant). 
 (f) If at any time after the amount of the Security Deposit is increased pursuant to subsections (d) and (e) above, (i) there is no Breach of Financial Covenant for two (2) consecutive fiscal years of the Guarantor, and
provided further that (ii) there is no default under any of the terms, covenants or conditions in the Lease, as amended by this Third Amendment, on Tenant’s part to observe, perform or comply with, Tenant may request that the total amount
of the Security Deposit be reduced by the Increased Security Deposit Amount, in which event, provided Landlord has confirmed the satisfaction of the conditions set forth in the preceding clauses (i) and (ii), and provided further that the
amount of the Security Deposit being held by Landlord pursuant to this Section is the total amount required hereunder, the total amount of the Security Deposit shall be reduced by the Increased Security Deposit, and Landlord shall accept an
amendment to the Letter of Credit then being held by Landlord to effectuate such reduction. If after such reduction there are one or more Breaches of Financial Covenant, the provisions of subsections (d) and (e) above shall again apply.

 5. AS-IS CONDITION; EXISTING CONDUITS: ALTERATIONS; RISERS 
 (a) Notwithstanding anything contained herein or in the Lease to the contrary, Tenant acknowledges that it has made a full and complete
inspection of the Third Additional Premises and is thoroughly familiar with the condition thereof, and agrees to accept possession of the Third Additional Premises on the respective Third Additional Premises Commencement Dates in their then “as
is” condition, including, without limitation, the existing pre-action sprinkler system servicing Third Additional Premises—Space A and the “wet” sprinkler system servicing Third Additional Premises—Space B). The taking of
possession of the Third Additional Premises by Tenant shall be conclusive evidence as against Tenant that at the time such possession was so taken, the Third Additional Premises were in good and satisfactory condition. 
 (b) Landlord has advised Tenant, and Tenant acknowledges, that as of the date of this Third Amendment, conduits exist connecting the Third
Additional Premises to other suites and areas of the Building. To the extent that such conduits are not owned or used by Landlord, another tenant in the Building or other occupant of the Building, Tenant shall have the right to use these existing
conduits throughout the term of this Third Amendment and Landlord shall have no obligations, responsibility or liability with respect thereto. Landlord will cooperate with Tenant in developing a schedule of conduits to determine the route and
termination points of the conduits servicing the Third Additional Premises. 
  

 10 

 (c) All Alterations which may be required or desired by Tenant to equip, decorate and
furnish the Third Additional Premises for Tenant’s occupancy (the “Third Additional Premises Initial Alterations”) shall be performed (i) at Tenant’s sole cost and expense, (ii) in accordance with the applicable
provisions of the Lease, including, without limitation, Article 4, and (iii) in substantial compliance with the Third Additional Premises Initial Alterations Project Plan attached hereto as Exhibit E (the “Project Plan”). 

(d) If Tenant requires riser space to connect Third Additional Premises - Space B to Tenant’s Generator and/or
Third Additional Premises - Space A or the 15th Floor
Premises, then Landlord shall make such riser space available to Tenant in accordance with, and subject to, the provisions of Section 10.8 of the Lease. 
 6. BROKERAGE 
 Landlord and Tenant covenant, warrant and represent
to each other that there was no broker or finder instrumental in consummating this Third Amendment and that they have had no conversations or negotiations with any broker or finder except Taconic Management Company LLC and CB Richard Ellis, Inc.
(collectively, the “Broker”) concerning this Third Amendment or the renting of the Third Additional Premises to Tenant. Landlord and Tenant agree to indemnify and hold each other harmless from and against any claims for a brokerage,
finder’s or other commission or fee arising out of any conversations or negotiations had by the indemnifying party with any broker or finder other than the Broker with respect to this Third Amendment or the renting of the Third Additional
Premises to Tenant. Landlord agrees to pay any fee or commission owing to the Broker pursuant to separate agreements made by Landlord and the Broker. 
 7. MISCELLANEOUS 
 (a) Except as otherwise provided herein, all of
the terms, covenants, conditions and provisions of the Lease shall remain and continue unmodified, in full force and effect and binding upon the parties hereto, their heirs, administrators, executors and their permitted assigns. 
 (b) This Third Amendment sets forth the entire agreement between the parties regarding the letting of the Third Additional Premises to
Tenant, superseding all prior agreements and understandings, written and oral, regarding the letting of the Third Additional Premises to Tenant, and may not be altered or modified except by a writing signed by both parties. 
 (c) Landlord and Tenant each represent and warrant to the other that it has not relied upon any representation or warranty, express or
implied, in entering into this Third Amendment, except those which are set forth herein. 
 (d) This Third Amendment shall be
governed by and construed in accordance with the laws of the State of New York. 
  

 11 

 (e) The covenants and agreements herein contained shall bind and inure to the benefit of
Landlord, its successors and assigns, and Tenant, its successors and assigns. If any of the provisions of this Third Amendment, or its application to any situation, shall be invalid or unenforceable to any extent, the remainder of this Third

by Tenant shall confer no rights nor impose any obligation on Landlord unless and until both Landlord and Tenant shall have executed this Third Amendment and duplicate originals thereof shall have been delivered by Landlord and Tenant to each other.

 (h) The Statement of Facts first set forth in this Third Amendment and the exhibit and schedule attached hereto are
incorporated into this Third Amendment and are, and shall for all purposes be deemed to be, a part of this Third Amendment.
