RECITALS

A. Each Subsidiary Guarantor is a subsidiary of Globix Corporation, a Delaware corporation (the “Company”).

B. For general corporate purposes, the Company has entered into one or more Note Purchase Agreements dated as of December 13, 2005 (each, a “Note Purchase Agreement”) between the Company and each of the purchasers named on Schedule A thereto (the “Initial Note Purchasers” the Initial Note Purchasers, together with their successors, assigns or any other future holder of the Notes (as defined below), the “Holders”), providing for, inter alia, the issue and sale by the Company to the Initial Note Purchasers of its Senior Secured Notes due May 1, 2008 (the “Notes”).

C. The Initial Note Purchasers have required as a condition to their purchase of the Notes that the Company cause each of the undersigned to enter into this Guaranty, and to cause certain other Domestic Restricted Subsidiaries (as defined in the Note Purchase Agreement) to enter into a Guaranty Supplement, and the Company has agreed to cause each of the undersigned to execute this Guaranty and to cause such Domestic Restricted Subsidiaries to execute a Guaranty Supplement, in order to induce the Initial Note Purchasers to purchase the Notes and thereby benefit the Company and the undersigned by providing funds for general corporate purposes.

D. Each of the Subsidiary Guarantors will derive substantial direct and indirect benefit from the sale of the Notes to the Initial Note Purchasers.

NOW, THEREFORE, as required by Section 2.2 of each Note Purchase Agreement and in consideration of the premises and other good and valuable consideration, the receipt and sufficiency whereof are hereby acknowledged, each Subsidiary Guarantor does hereby covenant and agree, jointly and severally, as follows:

1.	DEFINITIONS.

Capitalized terms used herein shall have the meanings set forth in the Note Purchase Agreement unless herein defined or the context shall otherwise require.

2.	GUARANTY OF NOTES AND NOTE PURCHASE AGREEMENTS.

(a) Each Subsidiary Guarantor jointly and severally does hereby irrevocably, absolutely and unconditionally guarantee unto the Holders: (1) the full and timely payment of the principal of, premium, if any, and interest on the Notes from time to time outstanding, as and when such payments shall become due and payable whether by lapse of time, upon redemption or prepayment, by extension or by acceleration or declaration or otherwise (including (to the extent legally enforceable) interest due on overdue payments of principal, premium, if any, or interest at the rate set forth in the Notes) in Federal or other immediately available funds of the United States of America which at the time of payment or demand therefor shall be legal tender for the payment of public and private debts, and (2) the full and timely performance and observance by the Company of each and all of the obligations, covenants and agreements required to be performed or owed by the Company under the terms of the Notes and each Note Purchase Agreement.

(b) The liability of each Subsidiary Guarantor under this Guaranty shall not exceed an amount equal to a maximum amount as will, after giving effect to such maximum amount and all other liabilities of such Subsidiary Guarantor, contingent or otherwise, result in the obligations of such Subsidiary Guarantor hereunder not constituting a fraudulent transfer, obligation or conveyance.

3.	GUARANTY OF PAYMENT AND PERFORMANCE.

This is a guarantee of payment and performance and each Subsidiary Guarantor hereby waives, to the fullest extent permitted by law, any right to require that any action on or in respect of any Note or any Note Purchase Agreement be brought against the Company or any other Person or that resort be had to any direct or indirect security for the Notes or for this Guaranty or any other remedy. Any Holder may, at its option, proceed hereunder against any Subsidiary Guarantor in the first instance to collect monies when due, the payment of which is guaranteed hereby, without first proceeding against the Company or any other Person and without first resorting to any direct or indirect security for the Notes or for this Guaranty or any other remedy. The liability of each Subsidiary Guarantor hereunder shall in no way be affected or impaired by any acceptance by any Holder of any direct or indirect security for, or other guaranties of, any Indebtedness, liability or obligation of the Company or any other Person to any Holder or by any failure, delay, neglect or omission by any Holder to realize upon or protect any such guarantees, Indebtedness, liability or obligation or any notes or other instruments evidencing the same or any direct or indirect security therefor or by any approval, consent, waiver, or other action taken, or omitted to be taken by any such Holder.

The covenants and agreements on the part of the Subsidiary Guarantors herein contained shall take effect as joint and several covenants and agreements, and references to the Subsidiary Guarantors shall take effect as references to each of them and none of them shall be released from liability hereunder by reason of the guarantee ceasing to be binding as a continuing guarantee on any other of them.

(xi) any defense whatsoever that: (1) the Company or any other Person might have to the payment of the Notes (principal, premium, if any, or interest), other than payment thereof in accordance with the terms thereof, or (2) the Company or any other Person might have to the performance or observance of any of the provisions of the Notes, any Note Purchase Agreement, the Security Documents or any other agreement, whether through the satisfaction or purported satisfaction by the Company or any other Person of its debts due to any cause such as bankruptcy, insolvency, receivership, merger,

-6-

consolidation, reorganization, dissolution, liquidation, winding-up or otherwise, other than the defense of indefeasible payment in full of the Notes; or

(xii) any act or failure to act with regard to the Notes, any Note Purchase Agreement, the Security Documents, this Guaranty or any other agreement or anything which might vary the risk of any Subsidiary Guarantor or any other Person; or

(xiii) any other circumstance which might otherwise constitute a defense available to, or a discharge of, any Subsidiary Guarantor or any other Person in respect of the obligations of any Subsidiary Guarantor or other Person under this Guaranty or any other agreement, other than the defense of indefeasible payment in full of the Notes;

provided that the specific enumeration of the above-mentioned acts, failures or omissions shall not be deemed to exclude any other acts, failures or omissions, though not specifically mentioned above, it being the purpose and intent of this Guaranty and the parties hereto that the obligations of each Subsidiary Guarantor shall be absolute and unconditional and shall not be discharged, impaired or varied except by the payment of the principal of, premium, if any, and interest on the Notes in accordance with their respective terms whenever the same shall become due and payable as in the Notes provided, at the place specified in and all in the manner and with the effect provided in the Notes and each Note Purchase Agreement, as each may be amended or modified from time to time. Without limiting the foregoing, it is understood that repeated and successive demands may be made and recoveries may be had hereunder as and when, from time to time, the Company shall default under or in respect of the terms of the Notes or any Note Purchase Agreement and that notwithstanding recovery hereunder for or in respect of any given default or defaults by the Company under the Notes or any Note Purchase Agreement, this Guaranty shall remain in full force and effect and shall apply to each and every subsequent default.

(d) All rights of any Holder may be transferred or assigned at any time and shall be considered to be transferred or assigned at any time or from time to time upon the transfer of such Note whether with or without the consent of or notice to the Subsidiary Guarantors under this Guaranty or to the Company.

(e) To the extent of any payments made under this Guaranty, the Subsidiary Guarantors shall be subrogated to the rights of the Holder or Holders upon whose Notes such payment was made, but each Subsidiary Guarantor covenants and agrees that such right of subrogation shall be junior and subordinate in right of payment to the prior indefeasible final payment in cash in full of all amounts due and owing by the Company with respect to the Notes and each Note Purchase Agreement and by the Subsidiary Guarantors under this Guaranty, and the Subsidiary Guarantors shall not take any action to enforce such right of subrogation, and the Subsidiary Guarantors shall not accept any payment in respect of such right of subrogation, until all amounts owed by the Company under or in respect of the Notes and each Note Purchase Agreement and all amounts owed by the Subsidiary Guarantors hereunder have indefeasibly been finally paid in full. If any amount shall be paid to any Subsidiary Guarantor in violation of the preceding sentence at any time prior to the indefeasible payment in cash in full of the Notes and all other amounts payable under the Notes, each Note Purchase Agreement and this Guaranty, such amount shall be held in trust for the benefit of the Holders and shall forthwith be

-7-

paid to the Holders to be credited and applied to the amounts due or to become due with respect to the Notes and all other amounts payable under each Note Purchase Agreement and this Guaranty, whether matured or unmatured.

(f) To the extent of any payments made under this Guaranty, each Subsidiary Guarantor making such payment shall have a right of contribution from the other Subsidiary Guarantors, but such Subsidiary Guarantor covenants and agrees that such right of contribution shall be subordinate in right of payment to the rights of the Holders for which full payment has not been made or provided for and, to that end, such Subsidiary Guarantor agrees not to claim or enforce any such right of contribution unless and until all of the Notes and all other sums due and payable under any Note Purchase Agreement have been fully and irrevocably paid and discharged.

(g) Each Subsidiary Guarantor agrees that to the extent the Company or any other Person makes any payment on any Note, which payment or any part thereof is subsequently invalidated, voided, declared to be fraudulent or preferential, set aside, recovered, rescinded or is required to be retained by or repaid to a trustee, receiver, or any other Person under any bankruptcy code, common law, or equitable cause, then and to the extent of such payment, the obligation or the part thereof intended to be satisfied shall be revived and continued in full force and effect with respect to the Subsidiary Guarantors’ obligations hereunder, as if said payment had not been made. The liability of the Subsidiary Guarantors hereunder shall not be reduced or discharged, in whole or in part, by any payment to any Holder from any source that is thereafter paid, returned or refunded in whole or in part by reason of the assertion of a claim of any kind relating thereto, including, but not limited to, any claim for breach of contract, breach of warranty, preference, illegality, invalidity, or fraud asserted by any account debtor or by any other Person.

(h) No Holder shall be under any obligation: (1) to marshal any assets in favor of the Subsidiary Guarantors or in payment of any or all of the liabilities of the Company under or in respect of the Notes or the obligations of the Subsidiary Guarantors hereunder or (2) to pursue any other remedy that the Subsidiary Guarantors may or may not be able to pursue themselves and that may lighten the Subsidiary Guarantors’ burden, any right to which each Subsidiary Guarantor hereby expressly waives.

(c) The execution, delivery and performance by such Subsidiary Guarantor of this Guaranty will not (1) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of such Subsidiary Guarantor or any of its subsidiaries under any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, charter document or by-law, or any other agreement or instrument to which such Subsidiary Guarantor or any of its subsidiaries is bound or by which such Subsidiary Guarantor or any of its subsidiaries or any of their respective properties may be bound or affected, (2) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to such Subsidiary Guarantor or any of its subsidiaries or (3) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to such Subsidiary Guarantor or any of its subsidiaries.

(b) The Subsidiary Guarantors will provide each Holder (irrespective of the amount of Notes then owned by it) with sufficient information, sufficiently far in advance of the date a decision is required, to enable such Holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof. The Subsidiary Guarantors will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 9 to each Holder promptly following the date on which it is executed and delivered by, or receives the consent or approval of, the Required Holders.

(c) The Subsidiary Guarantors will not, directly or indirectly pay or cause to be paid any remuneration, whether by way of fee or otherwise, or grant any security, to any Holder as consideration for or as an inducement to the entering into by any Holder of any waiver or amendment of any of the terms and provisions hereof unless such remuneration is concurrently paid, or security is concurrently granted, on the same terms, ratably to each Holder even if such Holder did not consent to such waiver or amendment.

(d) Any amendment or waiver consented to as provided in this Section 9 applies equally to all Holders and is binding upon them and upon each future Holder and upon the Subsidiary Guarantors. No such amendment or waiver will extend to or affect any obligation, covenant or agreement not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Subsidiary Guarantors and any Holder nor any delay in exercising any rights hereunder shall operate as a waiver of any rights of any Holder. As used herein, the term “this Guaranty” and references thereto shall mean this Guaranty as it may from time to time be amended or supplemented.

(e) Solely for the purpose of determining whether the Holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Guaranty, Notes directly or indirectly owned by any Subsidiary Guarantor, the Company or any of their respective subsidiaries shall be deemed not to be outstanding.

10.

MISCELLANEOUS.

No delay or omission to exercise any right or power accruing upon any default, omission or failure of performance hereunder shall impair any such right or power or shall be construed to be a waiver thereof but any such right or power may be exercised from time to time and as often as may be deemed expedient.

(d) If the whole or any part of this Guaranty shall be now or hereafter become unenforceable against any one or more of the Subsidiary Guarantors for any reason whatsoever or if it is not executed by any one or more of the Subsidiary Guarantors, this Guaranty shall nevertheless be and remain fully binding upon and enforceable against each other Subsidiary Guarantor as if it had been made and delivered only by such other Subsidiary Guarantors.

(e) This Guaranty shall be binding upon each Subsidiary Guarantor and its successors and assigns and shall inure to the benefit of each Holder and its successors and assigns so long as its Notes remain outstanding and unpaid.

(f) This Guaranty may be executed in any number of counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

SUBSIDIARY GUARANTY SUPPLEMENT

To the Holders of the Senior Secured Notes due May 1, 2008 of

Globix Corporation (the “Company”)

Ladies and Gentlemen:

WHEREAS, the Company has issued its Senior Secured Notes due May 1, 2008 (the “Notes”), pursuant to those certain Note Purchase Agreements dated as of December 13, 2005 (the “Note Purchase Agreements”) between the Company and each of the purchasers named on Schedule A thereto (the “Purchasers” and together with their successors and assigns, the “Holders”).

WHEREAS, as a condition precedent to their purchase of the Notes, the Purchasers required that certain subsidiaries of the Company enter into a Subsidiary Guaranty Agreement as security for the Notes (the “Subsidiary Guaranty;” capitalized terms used without definition herein have the meanings ascribed to them in the Subsidiary Guaranty).
