 Exhibit 10.39 
 INCENTIVE STOCK OPTION AGREEMENT 
 THE TELX GROUP, INC. 
 This AGREEMENT (this “Agreement”) is made as of the         
day of                      200_, between THE TELX GROUP, INC. (the “Company”), a Delaware corporation, and
                                         
                   , an employee of the Company, with an address of
                                         
                                         
   (the “Employee”). 
 WHEREAS, this Agreement is an “Option Agreement” as such term is
defined and used in The Telx Group, Inc. 2007 Employee Stock Plan (the “Plan”); 
 WHEREAS, any capitalized terms used
herein and not otherwise defined herein have the same meanings as in the Plan; 
 WHEREAS, on
                    , 20__, the Board of Directors of the Company granted to the Employee an Option to purchase shares of its common stock,
par value $.00001 per share (the “Shares”), under and for the purposes set forth in the Plan; and 
 WHEREAS, it is
intended that the Option so granted qualify as an incentive stock option (an “ISO”). 
 NOW, THEREFORE, in
consideration of the mutual covenants hereinafter set forth and for other good and valuable consideration, the parties hereto agree as follows: 
  

	 	1.	GRANT OF OPTION. 

 The
Board of Directors of the Company has granted to the Employee the right and option to purchase all or any part of an aggregate of
                         Shares, on the terms and conditions and subject to all the limitations set forth herein, under
United States securities and tax laws and in the Plan, which is incorporated herein by reference. The Employee acknowledges receipt of a copy of the Plan. 
  

	 	2.	PURCHASE PRICE. 

 The
purchase price of the Shares covered by the Option shall be $             per Share, subject to adjustment, as provided in the Plan, in the event of a stock split, reverse stock
split or other events affecting the holders of Shares after the date hereof (the “Purchase Price”). Payment shall be made in accordance with Paragraph 9 of the Plan, it being understood that the “cashless exercise” method of
payment permitted, in the discretion of the Administrator, by clause (c) thereof shall be deemed approved by the Administrator as shall any payment consisting of a combination of the methods described in clause (a) and (c) of such
Paragraph 9. If all or any part of the Option is exercised using the cashless exercise method, the Shares which are retained by the Company as payment of the purchase price for the Shares issued upon such exercise will be treated as having been
issued upon exercise of a Non-Qualified Option. 

	 	3.	EXERCISABILITY OF OPTION. 

 Subject to the terms and conditions set forth in this Agreement and the Plan, the Option granted hereby shall become exercisable as follows: 
  

	 	•	 	 as to 25% of the total number of Shares subject to the Option, on the first year anniversary of the date of this Agreement; and

  

	 	•	 	 thereafter, in 35 monthly installments of              Shares commencing on the 13th
month anniversary of the date of this Agreement, and a final installment of              Shares on the fourth anniversary of the date of this Agreement. 

The foregoing rights are cumulative and are subject to the other terms and conditions of this Agreement and the Plan. 
  

	 	4.	TERM OF OPTION. 

 The
Option shall terminate ten years from the date of this Agreement or, if the Employee owns as of the date hereof more than 10% of the total combined voting power of all classes of capital stock of the Company or an Affiliate, five years from the date
of this Agreement, but shall be subject to earlier termination as provided herein or in the Plan. 
 If the Employee ceases to
be an employee of the Company or of an Affiliate for any reason other than the death or Disability of the Employee or termination of the Employee’s employment for “cause” (as defined in the Plan), the Option may be exercised, if it
has not previously terminated, within three months after the date the Employee ceases to be an employee of the Company or an Affiliate, or within the originally prescribed term of the Option, whichever is earlier, but may not be exercised thereafter
except as set forth below. In such event, the Option shall be exercisable only to the extent that the Option has become exercisable and is in effect at the date of such cessation of employment. 
 If the Employee ceases to be an employee of the Company or of an Affiliate for any reason other than the death or Disability of the Employee
or termination of the Employee’s employment for “cause” (as defined in the Plan) but continues after termination of employment to provide service to the Company or an Affiliate as a consultant, this Option shall continue to vest in
accordance with Section 3 above as if this Option had not terminated until the Employee is no longer providing services to the Company. In such case, this Option shall automatically convert and be deemed a Non-Qualified Option as of the date
that is three months from termination of the Employee’s employment and this Option shall continue on the same terms and conditions set forth herein until such Employee is no longer providing service to the Company or an Affiliate. 

Notwithstanding the foregoing, in the event of the Employee’s Disability or death within three months after the termination of
employment for any reason other than termination of the Employee’s employment for “cause” (as defined in the Plan), the Employee or the Employee’s Survivors may exercise the Option within one year after the date of the
Employee’s termination of employment, but in no event after the date of expiration of the term of the Option. 
 In the
event the Employee’s employment with the Company or an Affiliate is terminated by the Employee’s employer for “cause” (as defined in the Plan), the Employee’s right to exercise any unexercised portion of this Option shall
cease immediately as of the time the Employee is notified his or her employment is terminated for “cause,” and this Option shall thereupon terminate. Notwithstanding anything herein to the contrary, if subsequent to the Employee’s
termination as an employee, but prior to

  

 2 

 
the exercise of the Option, the Board of Directors of the Company determines that, either prior or subsequent to the Employee’s termination, the Employee engaged in conduct which would
constitute “cause,” then the Employee shall immediately cease to have any right to exercise the Option and this Option shall thereupon terminate. 
 In the event of the Disability (as determined in accordance with the Plan) or death of the Employee while an employee of the Company or of an Affiliate, the Option shall be exercisable by the Employee or
the Employee’s Survivors, as applicable, within one year after the Employee’s termination of employment for Disability or the date of death, as applicable, or, if earlier, within the term originally prescribed by the Option. In such event,
the Option shall be exercisable: 
  

	 	(a)	to the extent that the Option has become exercisable but has not been exercised as of the date of Disability or death, as applicable; and 

  

	 	(b)	in the event rights to exercise the Option accrue periodically, to the extent of a pro rata portion through the date of Disability or death, as applicable, of any
additional vesting rights that would have accrued on the next vesting date had the Employee not become Disabled or died. The proration shall be based upon the number of days accrued in the current vesting period prior to the date of Disability or
death, as applicable. 

  

	 	5.	METHOD OF EXERCISING OPTION. 

 Subject to the terms and conditions of this Agreement, the Option may be exercised by written notice to the Company or its designee, in substantially the form of Exhibit A attached hereto. Such notice shall state the number of Shares
with respect to which the Option is being exercised and shall be signed by the person exercising the Option. Payment of the purchase price for such Shares shall be made in accordance with Paragraph 9 of the Plan, it being understood that the
“cashless exercise” method of payment permitted, in the discretion of the Administrator, by clause (c) thereof shall be deemed approved by the Administrator as shall any payment consisting of a combination of the methods described in
clause (a) and (c) of such Paragraph 9. If all or any part of the Option is exercised using the cashless exercise method, the Shares which are retained by the Company as payment of the purchase price for the Shares issued upon such
exercise will be treated as having been issued upon exercise of a Non-Qualified Option. The Company shall deliver such Shares as soon as practicable after the notice shall be received; provided, however, that the Company may delay issuance of such
Shares until completion of any action or obtaining of any consent which the Company deems necessary under any applicable law (including, without limitation, state securities or “blue sky” laws). The Shares as to which the Option shall have
been so exercised shall be registered in the Company’s share register in the name of the person so exercising the Option (or, if the Option shall be exercised by the Employee and if the Employee shall so request in the notice exercising the
Option, shall be registered in the name of the Employee and another person jointly, with right of survivorship) and shall be delivered as provided above to or upon the written order of the person exercising the Option. In the event the Option shall
be exercised, pursuant to Section 4 hereof, by any person other than the Employee, such notice shall be accompanied by appropriate proof of the right of such person to exercise the Option. All Shares that shall be purchased upon the exercise of
the Option as provided herein shall be fully paid and nonassessable. 
  

	 	6.	PARTIAL EXERCISE. 

 Exercise of this Option to the extent above stated may be made in part at any time and from time to time within the above limits, except that no fractional share shall be issued pursuant to this Option. 
  

 3 

	 	7.	NON-ASSIGNABILITY. 

 The
Option shall not be transferable by the Employee otherwise than (a) by will or by the laws of descent and distribution, or (b) pursuant to a qualified domestics relation order (as defined by the Code or Title I of the Employee Retirement
Income Security Act or the rules thereunder); provided, that, in the case of a transfer pursuant to this clause (b), the Option shall automatically convert and be deemed a Non-Qualified Option as of the date of such transfer, or (c) with the
prior consent of the Administrator. Except in the case of a transfer permitted by this Section 7, the Option shall be exercisable, during the Employee’s lifetime, only by the Employee (or, in the event of legal incapacity or incompetency,
by the Employee’s guardian or representative) and shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer,
assignment, pledge, hypothecation or other disposition of the Option or of any rights granted hereunder contrary to the provisions of this Section 7, or the levy of any attachment or similar process upon the Option, shall be null and void.

  

	 	8.	NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE. 

 The Employee shall have no rights as a stockholder with respect to Shares subject to this Agreement until registration of the Shares in the Company’s share register in the name of the Employee.
Except as is expressly provided in the Plan with respect to certain changes in the capitalization of the Company, no adjustment shall be made for dividends or similar rights for which the record date is prior to the date of such registration.

  

	 	9.	ADJUSTMENTS. 

 The Plan
contains provisions covering the treatment of Options in a number of contingencies such as stock splits and mergers. Provisions in the Plan for adjustment with respect to stock subject to Options and the related provisions with respect to successors
to the business of the Company are hereby made applicable hereunder and are incorporated herein by reference. 
  

	 	10.	TAXES. 

 The Employee
acknowledges that any income or other taxes due from him or her with respect to this Option or the Shares issuable pursuant to this Option shall be the Employee’s responsibility. The Employee acknowledges and agrees that (a) the Employee
was free to use professional advisors of his or her choice in connection with this Agreement, has received advice from his or her professional advisors in connection with this Agreement, understands its meaning and import, and is entering into this
Agreement freely and without coercion or duress; (b) the Employee has not received and is not relying upon any advice, representations or assurances made by or on behalf of the Company or any Affiliate or any employee of or counsel to the
Company or any Affiliate regarding any tax or other effects or implications of the Option, the Shares or other matters contemplated by this Agreement; and (c) neither the Company, its Affiliates, nor any of its officers or directors, shall be
held liable for any applicable costs, taxes or penalties associated with the Option if, in fact, the Internal Revenue Service were to determine that the Option constitutes deferred compensation under Section 409A of the Code. 
 In the event of a Disqualifying Disposition (as defined in Section 15 below) or if the Option is converted into a Non-Qualified Option
and such Non-Qualified Option is exercised, the Company may withhold from the Employee’s remuneration, if any, the minimum statutory amount of federal, state and local withholding taxes attributable to such amount that is considered
compensation includable in such person’s gross income. At the Company’s discretion, the amount required to be withheld may be withheld in cash from such remuneration, or in kind from the Shares otherwise deliverable to the

  

 4 

 
Employee on exercise of the Option. The Employee further agrees that, if the Company does not withhold an amount from the Employee’s remuneration sufficient to satisfy the Company’s
income tax withholding obligation, the Employee will reimburse the Company on demand, in cash, for the amount under-withheld. 
  

	 	11.	PURCHASE FOR INVESTMENT. 

 Unless the offering and sale of the Shares to be issued upon the particular exercise of the Option shall have been effectively registered under the Securities Act of 1933, as now in force or hereafter amended (the “1933 Act”), the
Company shall be under no obligation to issue the Shares covered by such exercise unless and until the following conditions have been fulfilled: 
  

	 	(a)	The person(s) who exercise the Option shall warrant to the Company, at the time of such exercise, that such person(s) are acquiring such Shares for their own respective
accounts, for investment, and not with a view to, or for sale in connection with, the distribution of any such Shares, in which event the person(s) acquiring such Shares shall be bound by the provisions of the following legend which shall be
endorsed upon any certificate(s) evidencing the Shares issued pursuant to such exercise: 

 “The shares
represented by this certificate have been taken for investment and they may not be sold or otherwise transferred by any person, including a pledgee, unless (a) either (i) a Registration Statement with respect to such shares shall be
effective under the Securities Act of 1933, as amended, or (ii) the Company shall have received an opinion of counsel satisfactory to it that an exemption from registration under such Act is then available, and (b) there shall have been
compliance with all applicable state securities laws;” and 
  

	 	(b)	If the Company so requires, the Company shall have received an opinion of its counsel that the Shares may be issued upon such particular exercise in compliance with the
1933 Act without registration thereunder. Without limiting the generality of the foregoing, the Company may delay issuance of the Shares until completion of any action or obtaining of any consent which the Company deems necessary under any
applicable law (including, without limitation, state securities or “blue sky” laws). 

  

	 	12.	RESTRICTIONS ON TRANSFER OF SHARES. 

 (a) The Shares acquired by the Employee pursuant to the exercise of the Option granted hereby shall not be transferred by the Employee except as permitted herein. 
 (b) In the event of the Employee’s termination of employment for any reason, the Company shall have the option, but not the obligation,
to repurchase all or any part of the Shares issued pursuant to this Agreement (including, without limitation, Shares purchased after termination of employment, Disability or death in accordance with Section 4 hereof). In the event the Company
does not, upon the termination of employment of the Employee (as described above), exercise its option pursuant to this Section 12(b), the restrictions set forth in the balance of this Agreement shall not thereby lapse, and the Employee, for
himself or herself, his or her heirs, legatees, executors, administrators and other successors in interest, agrees that the Shares shall remain subject to such restrictions. The following provisions shall apply to a repurchase under this
Section 12(b): 
  

	 	(i)	The per share repurchase price of the Shares to be sold to the Company upon exercise of its option under this Section 12(b) shall be equal to the Fair Market Value
of each such Share determined in accordance with the Plan as of the date of termination of employment; provided, however, in the event of a termination by the Company for “cause” (as defined in the Plan), the per share repurchase price of
the Shares to be sold to the Company upon exercise of its option under this Section 12(b) shall be equal to the Purchase Price.  

  

 5 

	 	(ii)	The Company’s option to repurchase the Employee’s Shares in the event of termination of employment shall be valid for a period of 12 months commencing with
the date of such termination of employment. 

  

	 	(iii)	In the event the Company shall be entitled to and shall elect to exercise its option to repurchase the Employee’s Shares under this Section 12(b), the Company
shall notify the Employee, or in case of death, his or her Survivor, in writing of its intent to repurchase the Shares. Such written notice may be mailed by the Company up to and including the last day of the time period provided for in
Section 12(b)(ii) for exercise of the Company’s option to repurchase. 

  

	 	(iv)	The written notice to the Employee shall specify the address at, and the time and date on, which payment of the repurchase price is to be made (the
“Closing”). The date specified shall not be less than ten days nor more than 60 days from the date of the mailing of the notice, and the Employee or his or her successor in interest with respect to the Shares shall have no further rights
as the owner thereof from and after the date specified in the notice. At the Closing, the repurchase price shall be delivered to the Employee or his or her successor in interest and the Shares being purchased, duly endorsed for transfer, shall, to
the extent that they are not then in the possession of the Company, be delivered to the Company by the Employee or his or her successor in interest. 

 In the event that the Employee or his or her successor in interest fails to deliver the Shares to be repurchased by the Company under this Agreement, the Company may elect (i) to establish a
segregated account in the amount of the repurchase price, such account to be turned over to the Employee or his or her successor in interest upon delivery of such Shares, and (ii) immediately to take such action as is appropriate to transfer
record title of such Shares from the Employee to the Company and to treat the Employee and such Shares in all respects as if delivery of such Shares had been made as required by this Agreement. The Employee hereby irrevocably grants the Company a
power of attorney which shall be coupled with an interest for the purpose of effectuating the preceding sentence. 
 (c) Upon
acquiring any Shares pursuant to the exercise of the Option, the Employee agrees to become a party to any stockholders’ agreement among the Company and all or some of its stockholders (a “Company Stockholders’ Agreement”).

 (d) If the Company shall pay a stock dividend or declare a stock split on or with respect to any of its Common Stock, or
otherwise distribute securities of the Company to the holders of its Common Stock, the number of shares of stock or other securities of the Company issued with respect to the shares then subject to the restrictions contained in this Agreement shall
be added to the Shares subject to the Company’s rights to repurchase pursuant to this Agreement. If the Company shall distribute to its stockholders shares of stock of another corporation, the shares of stock of such other corporation
distributed with respect to the Shares then subject to the restrictions contained in this Agreement shall be added to the Shares subject to the Company’s rights to repurchase pursuant to this Agreement. 
  

 6 

 (e) If the outstanding shares of Common Stock of the Company shall be subdivided into a
greater number of shares or combined into a smaller number of shares, or in the event of a reclassification of the outstanding shares of Common Stock of the Company, or if the Company shall be a party to a merger, consolidation or capital
reorganization, there shall be substituted for the Shares then subject to the restrictions contained in this Agreement such amount and kind of securities as are issued in such subdivision, combination, reclassification, merger, consolidation or
capital reorganization in respect of the Shares subject immediately prior thereto to the Company’s rights to repurchase pursuant to this Agreement. 
 (f) The Company shall not be required to transfer any Shares on its books which shall have been sold, assigned or otherwise transferred in violation of this Agreement, or to treat as owner of such Shares,
or to accord the right to vote as such owner or to pay dividends to, any person or organization to which any such Shares shall have been so sold, assigned or otherwise transferred, in violation of this Agreement. 
 (g) The Employee agrees that in the event the Company proposes to offer for sale to the public any of its equity securities and such
Employee is requested by the Company and any underwriter engaged by the Company in connection with such offering to sign an agreement restricting the sale or other transfer of Shares, then it will promptly sign such agreement and will not transfer,
whether in privately negotiated transactions or to the public in open market transactions or otherwise, any Shares or other securities of the Company held by him or her during such period as is determined by the Company and the underwriters, not to
exceed 180 days following the closing of the offering, plus such additional period of time as may be required to comply with Marketplace Rule 2711 of the National Association of Securities Dealers, Inc. or similar rules thereto (such period, the
“Lock-Up Period”). Such agreement shall be in writing and in form and substance reasonably satisfactory to the Company and such underwriter and pursuant to customary and prevailing terms and conditions. Notwithstanding whether the Employee
has signed such an agreement, the Company may impose stop-transfer instructions with respect to the Shares or other securities of the Company subject to the foregoing restrictions until the end of the Lock-Up Period. 
 (h) The Employee acknowledges and agrees that neither the Company, its stockholders nor its directors and officers, has any duty or
obligation to disclose to the Employee any material information regarding the business of the Company or affecting the value of the Shares before, at the time of, or following a termination of the employment of the Employee by the Company,
including, without limitation, any information concerning plans for the Company to make a public offering of its securities or to be acquired by or merged with or into another firm or entity. 
 (i) All certificates representing the Shares to be issued to the Employee pursuant to this Agreement shall have endorsed thereon a legend
substantially as follows: “The shares represented by this certificate are subject to restrictions set forth in an Incentive Stock Option Agreement dated
                    , 200     with this Company, a copy of which Agreement is available for inspection at the
offices of the Company or will be made available upon request.” In addition, so long as a Company Stockholders’ Agreement is in effect, all certificates representing the Shares to be issued to the Employee pursuant to this Agreement shall
have endorsed thereon a legend substantially as follows: “The shares represented by this certificate are subject to restrictions set forth in a Stockholders’ Agreement dated
                    , 200     with this Company, a copy of which Agreement is available for inspection at the
offices of the Company or will be made available upon request.” 
  

 7 

	 	13.	NO OBLIGATION TO EMPLOY. 

 The Company is not by the Plan or this Option obligated to continue the Employee as an employee of the Company or an Affiliate. The Employee acknowledges: (a) that the Plan is discretionary in nature and may be suspended or terminated
by the Company at any time; (b) that the grant of the Option is a one-time benefit which does not create any contractual or other right to receive future grants of options, or benefits in lieu of options; (c) that all determinations with
respect to any such future grants, including, but not limited to, the times when options shall be granted, the number of shares subject to each option, the option price, and the time or times when each option shall be exercisable, will be at the
sole discretion of the Company; (d) that the Employee’s participation in the Plan is voluntary; (e) that the value of the Option is an extraordinary item of compensation which is outside the scope of the Employee’s employment
contract, if any; and (f) that the Option is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits
or similar payments. 
  

	 	14.	OPTION IS INTENDED TO BE AN ISO. 

 The parties each intend that the Option be an ISO so that the Employee (or the Employee’s Survivors) may qualify for the favorable tax treatment provided to holders of Options that meet the standards of Section 422 of the Code.
Any provision of this Agreement or the Plan which conflicts with the Code so that this Option would not be deemed an ISO is null and void and any ambiguities shall be resolved so that the Option qualifies as an ISO. Nonetheless, if the Option is
determined not to be an ISO, the Employee understands that neither the Company nor any Affiliate is responsible to compensate him or her or otherwise make up for the treatment of the Option as a Non-Qualified Option and not as an ISO. The Employee
should consult with the Employee’s own tax advisors regarding the tax effects of the Option and the requirements necessary to obtain favorable tax treatment under Section 422 of the Code, including, but not limited to, holding period
requirements. 
 Notwithstanding the foregoing, to the extent that the Option is not deemed to be an ISO pursuant to
Section 422(d) of the Code because the aggregate fair market value (determined as of the date hereof) of any of the Shares with respect to which this ISO is granted becomes exercisable for the first time during any calendar year in excess of
$100,000, the portion of the Option representing such excess value shall be treated as a Non-Qualified Option and the Employee shall be deemed to have taxable income measured by the difference between the then fair market value of the Shares
received upon exercise and the price paid for such Shares pursuant to this Agreement. 
  

	 	15.	NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION. 

 The Employee agrees to notify the Company in writing immediately after the Employee makes a Disqualifying Disposition of any of the Shares acquired pursuant to the exercise of the Option. A Disqualifying
Disposition is defined in Section 424(c) of the Code and includes any disposition (including any sale) of such Shares before the later of (a) two years after the date the Employee was granted the Option, or (b) one year after the date
the Employee acquired Shares by exercising the Option, except as otherwise provided in Section 424(c) of the Code. If the Employee has died before the Shares are sold, these holding period requirements do not apply and no Disqualifying
Disposition can occur thereafter. 
  

 8 

	 	16.	NOTICES. 

 Any notices
required or permitted by the terms of this Agreement or the Plan shall be given by recognized courier service, facsimile, registered or certified mail, return receipt requested, addressed (a) if to the Company, to The Telx Group, Inc., 1 State
Street, 12th Floor, New York, New York 10004; Facsimile: 212.480.8384; Attention: Corporate Secretary, (b) if to the Employee, to the address set forth on the first page of this Agreement, or (c) to such other address or addresses of which
notice in the same manner has previously been given. Any such notice shall be deemed to have been given upon the earlier of receipt, one business day following delivery to a recognized courier service or three business days following mailing by
registered or certified mail. 
  

	 	17.	GOVERNING LAW. 

 This
Agreement shall be construed and enforced in accordance with the law of the State of Delaware, without giving effect to the conflict of law principles thereof. For the purpose of litigating any dispute that arises under this Agreement, the
parties hereby consent to exclusive jurisdiction in New York and agree that such litigation shall be conducted in the courts of New York, New York or the federal courts of the United States for the Southern District of New York. 
  

	 	18.	BENEFIT OF AGREEMENT. 

 Subject to the provisions of the Plan and the Stockholders Agreement and the other provisions hereof, this Agreement shall be for the benefit of and shall be binding upon the heirs, executors, administrators, successors and assigns of the
parties hereto. 
  

	 	19.	ENTIRE AGREEMENT. 

 This
Agreement, together with the Plan, embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject
matter hereof. No statement, representation, warranty, covenant or agreement not expressly set forth in this Agreement shall affect or be used to interpret, change or restrict the express terms and provisions of this Agreement; provided, however, in
any event, this Agreement shall be subject to and governed by the Plan. 
  

	 	20.	MODIFICATIONS AND AMENDMENTS. 

 The terms and provisions of this Agreement may be modified or amended as provided in the Plan. 
  

	 	21.	WAIVERS AND CONSENTS. 

 Except as provided in the Plan, the terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by written document executed by the party entitled to the benefits of such terms or provisions.
No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific
instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 
  

 9 

	 	22.	DATA PRIVACY. 

 By
entering into this Agreement, the Employee: (a) authorizes the Company and each Affiliate, and any agent of the Company or any Affiliate administering the Plan or providing Plan recordkeeping services, to disclose to the Company or any of its
Affiliates such information and data as the Company or any such Affiliate shall request in order to facilitate the grant of options and the administration of the Plan; (b) waives any data privacy rights he or she may have with respect to such
information; and (c) authorizes the Company and each Affiliate to store and transmit such information in electronic form. 
  

	 	23.	CONSENT OF SPOUSE. 

 If
the Employee is married as of the date of this Agreement, the Employee’s spouse shall execute a Consent of Spouse in the form of Exhibit B hereto, effective as of the date hereof. Such consent shall not be deemed to confer or convey to
the spouse any rights in the Shares that do not otherwise exist by operation of law or the agreement of the parties. If the Employee marries or remarries subsequent to the date hereof, the Employee shall, not later than 60 days thereafter, obtain
his or her new spouse’s acknowledgement of and consent to the existence and binding effect of Section 12(b) of this Agreement by such spouse’s executing and delivering a Consent of Spouse in the form of Exhibit B.

 Exhibit A 
 NOTICE OF EXERCISE OF INCENTIVE STOCK OPTION 
 FOR UNREGISTERED SHARES 

To: THE TELX GROUP, INC. 
 Ladies and Gentlemen: 
 I hereby exercise my Incentive Stock Option (the “Option”) to
purchase                      shares (the “Shares”) of the common stock, par value $0.0001 per share, of The Telx Group, Inc. (the “Company”), at the exercise price of
$         per share, pursuant to and subject to the terms of that certain Incentive Stock Option Agreement between the undersigned and the Company, dated
                    , 200_. 
 I am aware that the Shares have not been registered under the Securities Act of 1933, as amended (the “1933 Act”), or any state securities laws. I understand that the reliance by the Company on exemptions under the 1933 Act is
predicated in part upon the truth and accuracy of the statements by me in this Notice of Exercise. I understand that because the Shares have not been registered under the 1933 Act, I must continue to bear the economic risk of the investment for an
indefinite time and the Shares cannot be sold unless the Shares are subsequently registered under applicable federal and state securities laws or an exemption from such registration requirements is available. 
 I hereby represent and warrant that (a) I have been furnished with all information which I deem necessary to evaluate the merits and
risks of the purchase of the Shares; (b) I have had the opportunity to ask questions concerning the Shares and the Company and all questions posed have been answered to my satisfaction; (c) I have been given the opportunity to obtain any
additional information I deem necessary to verify the accuracy of any information obtained concerning the Shares and the Company; and (d) I have such knowledge and experience in financial and business matters that I am able to evaluate the
merits and risks of purchasing the Shares and to make an informed investment decision relating thereto. 
 I hereby represent
and warrant that I am purchasing the Shares for my own personal account for investment and not with a view to the sale or distribution of all or any part of the Shares. I agree that I will in no event sell or distribute or otherwise dispose of all
or any part of the Shares unless (a) there is an effective registration statement under the 1933 Act and applicable state securities laws covering any such transaction involving the Shares, or (b) the Company receives an opinion of my
legal counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or the Company otherwise satisfies itself that such transaction is exempt from registration. 
 I understand the terms and restrictions on the right to dispose of the Shares set forth in the The Telx Group, Inc. 2007 Employee Stock Plan and the Incentive Stock Option
Agreement, both of which I have carefully reviewed. I consent to the placing of a legend on my certificate for the Shares stating that the Shares have not been registered and setting forth the restriction on transfer contemplated hereby and to the
placing of a stop transfer order on the books of the Company and with any transfer agents against the Shares until the Shares may be legally resold or distributed without restriction or transferred in accordance with the terms of such restrictions.

  

 A-1 

 I understand that at the present time Rule 144 of the Securities and Exchange Commission
(the “SEC”) may not be relied on for the resale or distribution of the Shares by me. I understand that the Company has no obligation to me to register the sale of the Shares with the SEC and has not represented to me that it will register
the sale of the Shares. 
 I have considered the federal, state and local income tax implications of the exercise of my Option
and the purchase and subsequent sale of the Shares. 
 I am paying the Option exercise price for the Shares as follows:

  

	 	 ̈	in cash in an aggregate amount equal to:
$

 I,
                                         
                   , spouse of
                                         
   , acknowledge that I have read the Incentive Stock Option Agreement dated as of                     ,
200     (the “Agreement”), to which this Consent is attached as Exhibit B and that I know its contents. Capitalized terms used and not defined herein shall have the meanings assigned to such terms in the
Agreement. I am aware that by its provisions the Shares granted to my spouse pursuant to the Agreement are subject to a right of repurchase in favor of the Telx Group, Inc. (the “Company”) and that, accordingly, the Company has the right
to repurchase up to all of the Shares of which I may become possessed as a result of a gift from my spouse or a court decree and/or any property settlement in any domestic litigation.

accordance with the provisions of the Agreement. Further, as part of the consideration for the Agreement, I agree that at my death, if I have not disposed of any interest of mine in the Shares by an outright bequest of the Shares to my spouse, then
the Company shall have the same rights against my legal representative to exercise its rights of repurchase with respect to any interest of mine in the Shares as it would have had pursuant to the Agreement if I had acquired the Shares pursuant to a
court decree in domestic litigation. 
 I AM AWARE THAT THE LEGAL, FINANCIAL AND RELATED MATTERS CONTAINED IN THE AGREEMENT
ARE COMPLEX AND THAT I AM FREE TO SEEK INDEPENDENT PROFESSIONAL GUIDANCE OR COUNSEL WITH RESPECT TO THIS CONSENT. I HAVE EITHER SOUGHT SUCH GUIDANCE OR COUNSEL OR DETERMINED AFTER REVIEWING THE AGREEMENT CAREFULLY THAT I WILL WAIVE SUCH RIGHT.

 B-1Form of Non-Qualified Stock Option Agreement under the 2007 Employee Stock Plan

 Exhibit 10.40 
 NON-QUALIFIED STOCK OPTION AGREEMENT 
 THE TELX GROUP, INC. 
 This AGREEMENT (this “Agreement”) is made as of the      day of
             200  , between THE TELX GROUP, INC. (the “Company”), a Delaware corporation, and
                                        ,
an employee or director of, or consultant to, the Company with an address of
                                         
                    (the “Participant”). 
 WHEREAS, this Agreement is an “Option Agreement” as such term is defined and used in The Telx Group, Inc. 2007 Employee Stock Plan (the “Plan”); 
 WHEREAS, any capitalized terms used herein and not otherwise defined herein have the same meanings as in the Plan; 
 WHEREAS, on                  ,
20    , the Board of Directors of the Company granted to the Participant an Option to purchase shares of its common stock, par value $.00001 per share (the “Shares”), under and for the purposes set forth in the
Plan; and 
 WHEREAS, the Option so granted is a a Non-Qualified Option. 
 NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable consideration, the parties
hereto agree as follows: 
 1. GRANT OF OPTION. 
 The Board of Directors of the Company has granted to the Participant the right and option to purchase all or any part of an aggregate of
                     Shares, on the terms and conditions and subject to all the limitations set forth herein, under United States securities
and tax laws, and in the Plan, which is incorporated herein by reference. The Participant acknowledges receipt of a copy of the Plan. 
 2. PURCHASE PRICE. 
 The purchase price of the Shares covered by the Option shall be
$         per Share, subject to adjustment, as provided in the Plan, in the event of a stock split, reverse stock split or other events affecting the holders of Shares after the date hereof (the
“Purchase Price”). Payment shall be made in accordance with Paragraph 9 of the Plan, it being understood that the “cashless exercise” method of payment permitted, in the discretion of the Administrator, by clause (c) thereof
shall be deemed approved by the Administrator as shall any payment consisting of a combination of the methods described in clause (a) and (c) of such Paragraph 9. 

 3. EXERCISABILITY OF OPTION. 
 Subject to the terms and conditions set forth in this Agreement and the Plan, the Option granted hereby shall become exercisable as follows:

  

	 	•	 	 as to 25% of the total number of Shares subject to the Option (i.e.,
             Shares), on the first year anniversary of the date of this Agreement; and 

  

	 	•	 	 thereafter, in 35 monthly installments of              Shares commencing on the 13
th month anniversary of the date of this Agreement, and a
final installment of              Shares on the fourth anniversary of the date of this Agreement. 

 The foregoing rights are cumulative and are subject to the other terms and conditions of this Agreement and the Plan. 
 4. TERM OF OPTION. 
 The Option shall terminate ten years from the date of this Agreement, but shall be subject to earlier termination as provided herein or in the Plan. 
 If the Participant ceases to be an employee, director or consultant of the Company or of an Affiliate for any reason other than the death or Disability of the Participant or termination of the
Participant’s employment or retention for “cause” (as defined in the Plan), the Option may be exercised, if it has not previously terminated, within three months after the date the Participant ceases to be an employee, director or
consultant of the Company or an Affiliate, or within the originally prescribed term of the Option, whichever is earlier, but may not be exercised thereafter except as set forth below. In such event, the Option shall be exercisable only to the extent
that the Option has become exercisable and is in effect at the date of such cessation of service. 
 Notwithstanding the
foregoing, in the event of the Participant’s Disability or death within three months after the termination of service for any reason other than “cause” (as defined in the Plan), the Participant or the Participant’s Survivors may
exercise the Option within one year after the date of the Participant’s termination of service, but in no event after the date of expiration of the term of the Option. 
 In the event the Participant’s service is terminated by the Company or an Affiliate for “cause” (as defined in the Plan), the
Participant’s right to exercise any unexercised portion of this Option shall cease immediately as of the time the Participant is notified his or her service is terminated for “cause,” and this Option shall thereupon terminate.
Notwithstanding anything herein to the contrary, if subsequent to the termination of the Participant’s service, but prior to the exercise of the Option, the Board of Directors of the Company determines that, either prior or subsequent to the
Participant’s termination, the Participant engaged in conduct which would constitute “cause,” then the Participant shall immediately cease to have any right to exercise the Option and this Option shall thereupon terminate. 

 

 2 

 In the event of the Disability of the Participant (as determined in accordance with the
Plan) or death of the Participant while an employee, director or consultant of the Company or of an Affiliate, the Option shall be exercisable by the Participant or the Participant’s Survivors, as applicable, within one year after the
Participant’s termination of service for Disability or the date of death, as applicable, or, if earlier, within the term originally prescribed by the Option. In such event, the Option shall be exercisable: 
  

	 	(a)	to the extent that the Option has become exercisable but has not been exercised as of the date of Disability or death, as applicable; and 

  

	 	(b)	in the event rights to exercise the Option accrue periodically, to the extent of a pro rata portion through the date of Disability or death, as applicable, of any
additional vesting rights that would have accrued on the next vesting date had the Participant not become Disabled or died. The proration shall be based upon the number of days accrued in the current vesting period prior to the date of Disability or
death, as applicable. 

 5. METHOD OF EXERCISING OPTION. 
 Subject to the terms and conditions of this Agreement, the Option may be exercised by written notice to the Company or its designee, in
substantially the form of Exhibit A attached hereto. Such notice shall state the number of Shares with respect to which the Option is being exercised and shall be signed by the person exercising the Option. Payment of the purchase price for
such Shares shall be made in accordance with Paragraph 9 of the Plan, it being understood that the “cashless exercise” method of payment permitted, in the discretion of the Administrator, by clause (c) thereof shall be deemed approved
by the Administrator as shall any payment consisting of a combination of the methods described in clause (a) and (c) of such Paragraph 9. The Company shall deliver such Shares as soon as practicable after the notice shall be received,
provided, however, that the Company may delay issuance of such Shares until completion of any action or obtaining of any consent, which the Company deems necessary under any applicable law (including, without limitation, state securities or
“blue sky” laws). The Shares as to which the Option shall have been so exercised shall be registered in the Company’s share register in the name of the person so exercising the Option (or, if the Option shall be exercised by the
Participant and if the Participant shall so request in the notice exercising the Option, shall be registered in the name of the Participant and another person jointly, with right of survivorship) and shall be delivered as provided above to or upon
the written order of the person exercising the Option. In the event the Option shall be exercised, pursuant to Section 4 hereof, by any person other than the Participant, such notice shall be accompanied by appropriate proof of the right of
such person to exercise the Option. All Shares that shall be purchased upon the exercise of the Option as provided herein shall be fully paid and nonassessable. 
 6. PARTIAL EXERCISE. 
 Exercise of this Option to the extent above stated
may be made in part at any time and from time to time within the above limits, except that no fractional share shall be issued pursuant to this Option. 
  

 3 

 7. NON-ASSIGNABILITY. 
 The Option shall not be transferable by the Participant otherwise than (a) by will or by the laws of descent and distribution, or
(b) pursuant to a qualified domestic relations order (as defined by the Code or Title I of the Employee Retirement Income Security Act or the rules thereunder) or (c) with the prior consent of the Administrator. Except in the case of a
transfer permitted by this Section 7, the Option shall be exercisable, during the Participant’s lifetime, only by the Participant (or, in the event of legal incapacity or incompetency, by the Participant’s guardian or representative)
and shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other
disposition of the Option or of any rights granted hereunder contrary to the provisions of this Section 7, or the levy of any attachment or similar process upon the Option shall be null and void. 
 8. NO RIGHTS AS STOCKHOLDER UNTIL EXERCISE. 
 The Participant shall have no rights as a stockholder with respect to Shares subject to this Agreement until registration of the Shares in the Company’s share register in the name of the Participant.
Except as is expressly provided in the Plan with respect to certain changes in the capitalization of the Company, no adjustment shall be made for dividends or similar rights for which the record date is prior to the date of such registration.

 9. ADJUSTMENTS. 
 The Plan contains provisions covering the treatment of Options in a number of contingencies such as stock splits and mergers. Provisions in the Plan for adjustment with respect to stock subject to Options
and the related provisions with respect to successors to the business of the Company are hereby made applicable hereunder and are incorporated herein by reference. 
 10. TAXES. 
 The Participant acknowledges that upon exercise of the Option
the Participant will be deemed to have taxable income measured by the difference between the then fair market value of the Shares received upon exercise and the price paid for such Shares pursuant to this Agreement. The Participant acknowledges that
any income or other taxes due from him or her with respect to this Option or the Shares issuable pursuant to this Option shall be the Participant’s responsibility. The Participant acknowledges and agrees that (a) the Participant was free
to use professional advisors of his or her choice in connection with this Agreement, has received advice from his or her professional advisors in connection with this Agreement, understands its meaning and import, and is entering into this Agreement
freely and without coercion or duress; (b) the Participant has not received and is not relying upon any advice, representations or assurances made by or on behalf of the Company or any Affiliate or any employee of or counsel to the Company or
any Affiliate regarding any tax or other effects or implications of the Option, the Shares or other matters contemplated by this Agreement; and (c) neither the Company its Affiliates, nor any of its officers or directors, shall be held liable
for any applicable costs, taxes, or penalties associated with the Option if, in fact, the Internal Revenue Service were to determine that the Option constitutes deferred compensation under Section 409A of the Code. 
  

 4 

 The Participant agrees that the Company may withhold from the Participant’s
remuneration, if any, the minimum statutory amount of federal, state and local withholding taxes attributable to such amount that is considered compensation includable in such person’s gross income. At the Company’s discretion, the amount
required to be withheld may be withheld in cash from such remuneration, or in kind from the Shares otherwise deliverable to the Participant on exercise of the Option. The Participant further agrees that, if the Company does not withhold an amount
from the Participant’s remuneration sufficient to satisfy the Company’s income tax withholding obligation, the Participant will reimburse the Company on demand, in cash, for the amount under-withheld. 
 11. PURCHASE FOR INVESTMENT. 
 Unless the offering and sale of the Shares to be issued upon the particular exercise of the Option shall have been effectively registered under the Securities Act of 1933, as now in force or hereafter
amended (the “1933 Act”), the Company shall be under no obligation to issue the Shares covered by such exercise unless and until the following conditions have been fulfilled: 
  

	 	(a)	The person(s) who exercise the Option shall warrant to the Company, at the time of such exercise, that such person(s) are acquiring such Shares for their own respective
accounts, for investment, and not with a view to, or for sale in connection with, the distribution of any such Shares, in which event the person(s) acquiring such Shares shall be bound by the provisions of the following legend which shall be
endorsed upon any certificate(s) evidencing the Shares issued pursuant to such exercise: 

 “The shares
represented by this certificate have been taken for investment and they may not be sold or otherwise transferred by any person, including a pledgee, unless (a) either (i) a Registration Statement with respect to such shares shall be
effective under the Securities Act of 1933, as amended, or (ii) the Company shall have received an opinion of counsel satisfactory to it that an exemption from registration under such Act is then available, and (b) there shall have been
compliance with all applicable state securities laws;” and 
  

	 	(b)	If the Company so requires, the Company shall have received an opinion of its counsel that the Shares may be issued upon such particular exercise in compliance with the
1933 Act without registration thereunder. Without limiting the generality of the foregoing, the Company may delay issuance of the Shares until completion of any action or obtaining of any consent, which the Company deems necessary under any
applicable law (including, without limitation, state securities or “blue sky” laws). 

  

 5 

 12. RESTRICTIONS ON TRANSFER OF SHARES. 
  

	 	(a)	The Shares acquired by the Participant pursuant to the exercise of the Option granted hereby shall not be transferred by the Participant except as permitted herein.

  

	 	(b)	In the event of the Participant’s termination of service by the Company or an Affiliate for any reason, the Company shall have the option, but not the obligation,
to repurchase all or any part of the Shares issued pursuant to this Agreement (including, without limitation, Shares purchased after termination of employment, Disability or death in accordance with Section 4 hereof). In the event the Company
does not, upon the termination of service of the Participant (as described above), exercise its option pursuant to this Section 12(b), the restrictions set forth in the balance of this Agreement shall not thereby lapse, and the Participant for
himself or herself, his or her heirs, legatees, executors, administrators and other successors in interest, agrees that the Shares shall remain subject to such restrictions. The following provisions shall apply to a repurchase under this
Section 12(b): 

 (i) The per share repurchase price of the Shares to be sold to the Company upon exercise of
its option under this 
 Section 12(b) shall be equal to the Fair Market Value of each such Share determined in accordance
with the Plan as of the date of termination of service; provided, however, in the event of a termination by the Company for “cause” (as defined in the Plan), the per share repurchase price of the Shares to be sold to the Company upon
exercise of its option under this Section 12(b) shall be equal to the Purchase Price. 
 (ii) The Company’s option to
repurchase the Participant’s Shares in the event of termination of service shall be valid for a period of 12 months commencing with the date of such termination of service. 
 (iii) In the event the Company shall be entitled to and shall elect to exercise its option to repurchase the Participant’s Shares under
this Section 12(b), the Company shall notify the Participant, or in case of death, his or her Survivor, in writing of its intent to repurchase the Shares. Such written notice may be mailed by the Company up to and including the last day of the
time period provided for in Section 12(b)(ii) for exercise of the Company’s option to repurchase. 
 (iv) The written
notice to the Participant shall specify the address at, and the time and date on, which payment of the repurchase price is to be made (the “Closing”). The date specified shall not be less than ten days nor more than 60 days from the date
of the mailing of the notice, and the Participant or his or her successor in interest with respect to the Shares shall have no further rights as the owner thereof from and after the date specified in the notice. At the Closing, the repurchase price
shall be delivered to the Participant or his or her successor in interest and the Shares being purchased, duly endorsed for transfer, shall, to the extent that they are not then in the possession of the Company, be delivered to the Company by the
Participant or his or her successor in interest. 
  

 6 

 In the event that the Participant or his or her successor in interest fails to deliver the
Shares to be repurchased by the Company under this Agreement, the Company may elect (i) to establish a segregated account in the amount of the repurchase price, such account to be turned over to the Participant or his or her successor in
interest upon delivery of such Shares, and (ii) immediately to take such action as is appropriate to transfer record title of such Shares from the Participant to the Company and to treat the Participant and such Shares in all respects as if
delivery of such Shares had been made as required by this Agreement. The Participant hereby irrevocably grants the Company a power of attorney which shall be coupled with an interest for the purpose of effectuating the preceding sentence.

  

	 	(c)	Upon acquiring any Shares pursuant to the exercise of the Option, the Participant agrees to become a party to any stockholders’ agreement among the Company and all
or some of its stockholders (a “Company Stockholders’ Agreement”). 

  

	 	(d)	If the Company shall pay a stock dividend or declare a stock split on or with respect to any of its Common Stock, or otherwise distribute securities of the Company to
the holders of its Common Stock, the number of shares of stock or other securities of the Company issued with respect to the shares then subject to the restrictions contained in this Agreement shall be added to the Shares subject to the
Company’s rights to repurchase pursuant to this Agreement. If the Company shall distribute to its stockholders shares of stock of another corporation, the shares of stock of such other corporation, distributed with respect to the Shares then
subject to the restrictions contained in this Agreement, shall be added to the Shares subject to the Company’s rights to repurchase pursuant to this Agreement. 

  

	 	(e)	If the outstanding shares of Common Stock of the Company shall be subdivided into a greater number of shares or combined into a smaller number of shares, or in the
event of a reclassification of the outstanding shares of Common Stock of the Company, or if the Company shall be a party to a merger, consolidation or capital reorganization, there shall be substituted for the Shares then subject to the restrictions
contained in this Agreement such amount and kind of securities as are issued in such subdivision, combination, reclassification, merger, consolidation or capital reorganization in respect of the Shares subject immediately prior thereto to the
Company’s rights to repurchase pursuant to this Agreement. 

  

	 	(f)	The Company shall not be required to transfer any Shares on its books which shall have been sold, assigned or otherwise transferred in violation of this Agreement, or
to treat as owner of such Shares, or to accord the right to vote as such owner or to pay dividends to, any person or organization to which any such Shares shall have been so sold, assigned or otherwise transferred, in violation of this Agreement.

  

 7 

	 	(g)	The Participant agrees that in the event the Company proposes to offer for sale to the public any of its equity securities and such Participant is requested by the
Company and any underwriter engaged by the Company in connection with such offering to sign an agreement restricting the sale or other transfer of Shares, then it will promptly sign such agreement and will not transfer, whether in privately
negotiated transactions or to the public in open market transactions or otherwise, any Shares or other securities of the Company held by him or her during such period as is determined by the Company and the underwriters, not to exceed 180 days
following the closing of the offering, plus such additional period of time as may be required to comply with Marketplace Rule 2711 of the National Association of Securities Dealers, Inc. or similar rules thereto (such period, the “Lock-Up
Period”). Such agreement shall be in writing and in form and substance reasonably satisfactory to the Company and such underwriter and pursuant to customary and prevailing terms and conditions. Notwithstanding whether the Participant has signed
such an agreement, the Company may impose stop-transfer instructions with respect to the Shares or other securities of the Company subject to the foregoing restrictions until the end of the Lock-Up Period. 

  

	 	(h)	The Participant acknowledges and agrees that neither the Company, its stockholders nor its directors and officers, has any duty or obligation to disclose to the
Participant any material information regarding the business of the Company or affecting the value of the Shares before, at the time of, or following a termination of the employment of the Participant by the Company, including, without limitation,
any information concerning plans for the Company to make a public offering of its securities or to be acquired by or merged with or into another firm or entity. 

  

	 	(i)	All certificates representing the Shares to be issued to the Participant pursuant to this Agreement shall have endorsed thereon a legend substantially as follows:
“The shares represented by this certificate are subject to restrictions set forth in a Non-Qualified Stock Option Agreement dated             , 200   with this
Company, a copy of which Agreement is available for inspection at the offices of the Company or will be made available upon request.” In addition, so long as a Company Stockholders’ Agreement is in effect, all certificates representing the
Shares to be issued to the Participant pursuant to this Agreement shall have endorsed thereon a legend substantially as follows: “The shares represented by this certificate are subject to restrictions set forth in a Stockholders’ Agreement
dated             , 200   with this Company, a copy of which Agreement is available for inspection at the offices of the Company or will be made available upon
request.” 

  

 8 

 13. NO OBLIGATION TO MAINTAIN RELATIONSHIP. 
 The Company is not by the Plan or this Option obligated to continue the Participant as an employee, director or consultant of the Company or
an Affiliate. The Participant acknowledges: (a) that the Plan is discretionary in nature and may be suspended or terminated by the Company at any time; (b) that the grant of the Option is a one-time benefit which does not create any
contractual or other right to receive future grants of options, or benefits in lieu of options; (c) that all determinations with respect to any such future grants, including, but not limited to, the times when options shall be granted, the
number of shares subject to each option, the option price, and the time or times when each option shall be exercisable, will be at the sole discretion of the Company; (d) that the Participant’s participation in the Plan is voluntary;
(e) that the value of the Option is an extraordinary item of compensation which is outside the scope of the Participant’s employment contract, if any; and (f) that the Option is not part of normal or expected compensation for purposes
of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

 Exhibit A 
 NOTICE OF EXERCISE OF NON-QUALIFIED STOCK OPTION 
 FOR UNREGISTERED SHARES

 To: THE TELX GROUP, INC. 
 Ladies and Gentlemen: 
 I hereby exercise my Non-Qualified Stock Option (the “Option”) to
purchase             shares (the “Shares”) of the common stock, par value $0.0001 per share, of The Telx Group, Inc. (the “Company”), at the exercise price of
$        per share, pursuant to and subject to the terms of that certain Non-Qualified Stock Option Agreement between the undersigned and the Company, dated
            , 200  . 
 I am aware that the
Shares have not been registered under the Securities Act of 1933, as amended (the “1933 Act”), or any state securities laws. I understand that the reliance by the Company on exemptions under the 1933 Act is predicated in part upon the
truth and accuracy of the statements by me in this Notice of Exercise. I understand that because the Shares have not been registered under the 1933 Act, I must continue to bear the economic risk of the investment for an indefinite time and the
Shares cannot be sold unless the Shares are subsequently registered under applicable federal and state securities laws or an exemption from such registration requirements is available. 
 I hereby represent and warrant that (a) I have been furnished with all information which I deem necessary to evaluate the merits and
risks of the purchase of the Shares; (b) I have had the opportunity to ask questions concerning the Shares and the Company and all questions posed have been answered to my satisfaction; (c) I have been given the opportunity to obtain any
additional information I deem necessary to verify the accuracy of any information obtained concerning the Shares and the Company; and (d) I have such knowledge and experience in financial and business matters that I am able to evaluate the
merits and risks of purchasing the Shares and to make an informed investment decision relating thereto. 
 I hereby represent
and warrant that I am purchasing the Shares for my own personal account for investment and not with a view to the sale or distribution of all or any part of the Shares. 
 I agree that I will in no event sell or distribute or otherwise dispose of all or any part of the Shares unless (a) there is an effective registration statement under the 1933 Act and applicable
state securities laws covering any such transaction involving the Shares, or (b) the Company receives an opinion of my legal counsel (concurred in by legal counsel for the Company) stating that such transaction is exempt from registration or
the Company otherwise satisfies itself that such transaction is exempt from registration. 
  

 A-1 

 I understand the terms and restrictions on the right to dispose of the
Shares set forth in the The Telx Group, Inc. 2007 Employee
Stock Plan and the Non-Qualified Stock Option Agreement, both of which I have carefully reviewed. I consent to the placing of a legend on my certificate for the Shares stating that the Shares have not been registered and setting forth the
restriction on transfer contemplated hereby and to the placing of a stop transfer order on the books of the Company and with any transfer agents against the Shares until the Shares may be legally resold or distributed without restriction or
transferred in accordance with the terms of such restrictions. 
 I understand that at the present time Rule 144 of the
Securities and Exchange Commission (the “SEC”) may not be relied on for the resale or distribution of the Shares by me. I understand that the Company has no obligation to me to register the sale of the Shares with the SEC and has not
represented to me that it will register the sale of the Shares. 
 I have considered the federal, state and local income tax
implications of the exercise of my Option and the purchase and subsequent sale of the Shares. 
 I am paying the Option exercise
price for the Shares as follows: 
  ̈ in cash in an aggregate amount equal to:
$                     
  ̈ by cashless exercise 
  ̈
 other:
                                         
                    
 Please
issue the stock certificate for the Shares (check one): 
  ̈ to me; or

  ̈ to me and
                    , as joint tenants with right of survivorship 
 and mail the certificate to me at the following address:

             shares (the “Shares”) of the common stock, par value $0.0001 per share, of The Telx Group, Inc. (the “Company”), at the exercise price of

 Exhibit B 
 CONSENT OF SPOUSE 
 I,
                        , spouse of
                        , acknowledge that I have read the Non-Qualified Stock Option Agreement dated as of
            , 200   (the “Agreement”) to which this Consent is attached as Exhibit B and that I know its contents. Capitalized terms used and not defined
herein shall have the meanings assigned to such terms in the Agreement. I am aware that by its provisions the Shares granted to my spouse pursuant to the Agreement are subject to a right of repurchase in favor of The Telx Group, Inc. (the “Company”) and that, accordingly, the
Company has the right to repurchase up to all of the Shares of which I may become possessed as a result of a gift from my spouse or a court decree and/or any property settlement in any domestic litigation. 
 I hereby agree that my interest, if any, in the Shares subject to the Agreement shall be irrevocably bound by the Agreement and further
understand and agree that any community property interest I may have in the Shares shall be similarly bound by the Agreement. 
 I agree to the repurchase right described in Section 12(b) of the Agreement and I hereby consent to the repurchase of the Shares by the Company and the sale of the Shares by my spouse or my spouse’s legal representative in
accordance with the provisions of the Agreement. Further, as part of the consideration for the Agreement, I agree that at my death, if I have not disposed of any interest of mine in the Shares by an outright bequest of the Shares to my spouse, then
the Company shall have the same rights against my legal representative to exercise its rights of repurchase with respect to any interest of mine in the Shares as it would have had pursuant to the Agreement if I had acquired the Shares pursuant to a
court decree in domestic litigation. 
 I AM AWARE THAT THE LEGAL, FINANCIAL AND RELATED MATTERS CONTAINED IN THE AGREEMENT
ARE COMPLEX AND THAT I AM FREE TO SEEK INDEPENDENT PROFESSIONAL GUIDANCE OR COUNSEL WITH RESPECT TO THIS CONSENT. I HAVE EITHER SOUGHT SUCH GUIDANCE OR COUNSEL OR DETERMINED AFTER REVIEWING THE AGREEMENT CAREFULLY THAT I WILL WAIVE SUCH RIGHT. 

 Dated as of the      day of         ,
200  .
