If during all or part of any Lease Year the Rentable Area of the Building is not fully occupied by tenants, the Building Operating Expenses for such Lease Year shall be adjusted to reflect the Building Operating Expenses which would have been payable had the Building been fully occupied throughout such Lease Year. SECTION 5.2. PAYMENT OF TAXES AND BUILDING OPERATING EXPENSES. Landlord shall pay all Taxes and Building Operating Expenses and Tenant shall reimburse Landlord for Tenant's Share thereof, in accordance with this Section 5.2. 5.2.1. Payment Of Tenant's Share Of Taxes. 5.2.1.1 Tax Payment and Tax Statement, Tenant shall pay to Landlord as Additional Rent, an amount equal to Tenant's Share of Taxes for any Lease Year or Partial Lease Year in the manner set forth in this Section 5.2. 1. At any time during or after a Lease Year, Landlord may render to Tenant a statement (the "Tax Statement") showing (a) the Taxes for the Lease Year and (b) Tenant's Share of any such Taxes (the "Tax Payment"). Tenant shall pay to Landlord, in (2) equal installments, in advance, on June 1 and December 1 of each year, the Tax Payment shown on the Tax Statement. If the taxing authority changes the number or amount of installments of Taxes or the dates on which Taxes are required to be paid, then the amounts or the due dates of the installments of the Tax Payment shall be correspondingly revised so that the Tax Payment (or the installments thereof) will be due not more than thirty (30) days prior to the date the corresponding payment is due to such authority. If any additional Taxes are imposed during any Lease Year or if any Tax Statement contains an error, Landlord may at any time deliver revised Tax Statements to Tenant, and the provisions of this Section 5.2.1.1 regarding the timing of the Tax Payment shall apply to such revised Tax Statements. Landlord's failure to render a Tax Statement during any Lease Year or failure to make a demand under this Section 5.2.1 shall not prejudice Landlord's right to render a Tax Statement with respect to such Lease Year during any subsequent Lease Year or with respect to any subsequent Lease Year, and shall not affect Tenant's obligation to pay the Tax Payment for such Lease Year or act as a waiver of any kind. Whenever so requested, but not more than once a year, Landlord shall furnish Tenant with a reproduced copy of the tax bill for the Taxes for the current or next succeeding Lease Year, if theretofore issued by the taxing authority. 5.2.1.2 Adjustments of Tax Payment. The Tax Payment shall be prorated for any Partial Lease Year in which the Lease Term shall commence or end. If a Tax Statement is furnished to Tenant after the commencement of the Lease Year in respect of which such Tax Statement is rendered, Tenant shall, within thirty (30) days after receipt, pay to Landlord the amount shown thereon. If, after Tenant shall have made a Tax Payment and regardless of whether this Lease shall have terminated, Landlord shall receive a refund of any portion of the Taxes on which such payment shall have been based, Landlord shall have the option either to pay to Tenant Tenant's Share of the net refund after deduction of all expenses (including, but not limited to, attorneys' and appraisers' fees and disbursements and witnesses' fees) incurred by Landlord in connection with obtaining the refund or to credit such sum against subsequent Tax Payments; provided however, , that Tenant's Share of such refund shall be limited to the amount, if any, which Tenant had theretofore paid to Landlord in respect of Taxes for such Lease Year. 5.2.1.3 Miscellaneous Tax Matters. Tenant shall receive Tenant's Share of any discount that Landlord may receive by virtue of any early payment of Taxes or on account of any exemption or abatement of Taxes, and Taxes shall be calculated by taking such discounts into account. Subject to the second sentence of Section 5.1.7, Taxes shall be computed initially on the assessed valuation in effect at the time the Tax Statement is issued to Tenant, regardless of any then pending proceeding for reduction of such assessed valuation. Only Landlord shall be eligible to institute tax reduction or other proceedings to reduce the assessed valuation of the TELEHOUSE Complex or the Building or contest any item comprising Taxes. Notwithstanding the foregoing, tenant shall have the right to participate in, at Tenant's, sole cost and expense, or maintain, at Tenant's sole cost and expense, appropriate proceedings to seek reduction of any Tax imposed on Tenant's property under the provisions of the New York State Tax Law imposing a tax on telecommunications equipment. Tenant's liability for any Tax Payment due under this Section 5.2.1 shall survive the expiration or earlier termination of this Lease, and shall be payable within thirty (30) 18 <PAGE> days after demand therefor following such expiration or termination. In no event shall any adjustment of any Tax Payment hereunder result in a decrease in Base Rent. 5.2.2 Payment of Tenant's Share of Building Operating expenses, 5.2.2.1 Operating Expense Statement, Tenant shall pay to Landlord as Additional Rent an amount equal to Tenant's Share of Building Operating Expenses for any Lease Year or Partial Lease Year in the manner set forth in this Section 5.2.2.

For the first Lease Year, Tenant's Share of estimated Building Operating Expenses is set forth in Section 1.1 as the Initial Tenant's Share of Building Operating Expenses (the "Operating Expense Payment"). Landlord's failure to render an Operating Expense Statement during any Lease Year or failure to make a demand under this Section 5.2.2 shall not prejudice Landlord's right to render an Operating Expense Statement with respect to such Lease Year during any subsequent Lease Year or with respect to any subsequent Lease Year, and shall not affect Tenant's obligation to pay Tenant's Share of such Building Operating Expenses for such Lease Year or act as a waiver of any kind. Within thirty (30) days of receipt of an Operating Expense Statement, Tenant shall pay to Landlord a sum equal to one-twelfth (1/12th) of such estimated Building Operating Expenses multiplied by the number of months (including any partial months) to and including the then current month which have elapsed since the commencement of such Lease Year, less the aggregate of any payments made on account of Building Operating Expenses made since the commencement of such Lease Year pursuant to this Section 5.2.2; and, thereafter, commencing with the first day of the month following the furnishing to Tenant of an Operating Expense Statement and continuing monthly on the first day of every month thereafter until rendition of the next succeeding Operating Expense Statement, Tenant shall pay an amount equal to one-twelfth (1/12th) of Tenant's Share of such estimated Building Operating Expenses. 5.2.2.2 Miscellaneous Building Operating Expense Matters. Tenant's liability for Tenant's Share of Building Operating Expenses due under this Section 5.2.2 shall survive the expiration or earlier termination of this Lease, and shall be payable within thirty (30) days after demand therefore following such expiration or termination.

The costs of such service (which shall be at least one hundred fifteen percent (115%) of the cost to the Port Authority of the same quantity of electrical power) shall be paid by Tenant directly to the Port Authority on such terms and conditions as the Port Authority may establish. Notwithstanding the foregoing, if Tenant's consumption of electrical power exceeds the standard of forty (40) VoltAmps per square foot of Useable Area, Tenant shall pay as Additional Rent an amount calculated according to the Excessive Electricity Schedule annexed hereto as Exhibit "F".

In order that Landlord may at all times have ail necessary Information that it requires to maintain and protect its equipment, Tenant agrees that Tenant will not make any alteration of or addition to, the electrical equipment or wiring in the Premises without the prior written consent in each instance of Landlord (which shall not be unreasonably withheld) and, if required, of the Port Authority. 6.1.4 Requirements Applicable to Tenant.

The first category, referred to as "Essential Powers", is electrical power in quantity at least equal to one-half (1/2) of the quantity of electrical power normally consumed by Tenant during the time of year in which the interruption occurs in Tenant's operation of its lighting and air-conditioning equipment for office space. The second category, referred to as "Critical Power", is electrical power in quantity at least equal to the quantity of electrical power normally consumed by Tenant during the time of year in which the interruption occurs in Tenant's operation of its computers in the Premises. PROVIDED, that Landlord shall use its best efforts to furnish both Essential Power and Critical Power to the Site K position of the Premises at all times during any interruption of the Port Authority's service, but Landlord shall not be liable to Tenant for any loss, liability, damage or expense which Tenant may sustain or incur if (i) all or part of the emergency power system fails to operate or (ii) the electrical power supplied to the Site K position of the Premises by Landlord's emergency power system is interrupted due to an event of Force Majeure or otherwise or (iii) the 20 <PAGE> quantity or character of electrical power supplied by Landlord's emergency power system changes or is no longer available or suitable for Tenant's requirements, except for actual damage suffered by Tenant and resulting from Landlord's willful misconduct or gross negligence, and then only after actual notice thereof to Landlord and Landlord's failure to cure within a reasonable time.

Landlord may, from time to time, but not more frequently than once every three (3) years, increase the policy amount to be maintained by Tenant under this Section 7.2 as Landlord reasonably deems necessary in order to maintain adequate liability coverage, provided, that the policy amount does not exceed the policy amount required for other Tenants within the building and TELEHOUSE. SECTION 7.3 USE OF PREMISES. Tenant shall not do, or permit anything to be done, in or about the Premises which might, solely by reason of the particular nature of Tenant's use of the Premises: (a) increase any insurance rate with respect to the Building over the rate which would otherwise then be in effect, or (b) result in insurance companies of good standing refusing to insure the Building in amounts satisfactory to Landlord, or (c) result in the cancellation of any policy covering or relating to the Building. SECTION 7.4 WAIVER OF SUBROGATION. 7.4.1 Waiver Included in Policy. Landlord and Tenant shall each secure an appropriate clause in, or an endorsement upon, each property insurance policy required by this Article VII, pursuant to which the insurance 23 <PAGE> company waives subrogation or permits the insured, prior to any loss, to agree with a third party to waive any claim it might have against said third party without invalidating the coverage under the insurance policy. On Tenant's policies, the waiver of subrogation or permission for waiver of any claim shall extend to Landlord and its agents and employees and against other lessees in the Building, , provided that such other lessees agree to a waiver of their respective rights of subrogation against Tenant. On Landlord's policies, the waiver of subrogation or permission for waiver of any claim shall extend to Tenant and its agents and employees. If such waiver be unobtainable, the parties shall include in their property insurance policies (i) an express agreement that such policy shall not be invalidated if the insured waives or has waived before the casualty the right of recovery against any party responsible for a covered casualty or (ii) any other form of permission for the release of such responsible party. If such waiver, agreement or permission shall not be, or shall cease to be, obtainable without additional charge or at all, the insured party shall so notify the other party promptly after notice thereof. If the other party shall agree in writing to pay the insurer's additional charge therefor, such waiver, agreement or permission shall (if obtainable) be included in the policy. In the event either party's insurer shall refuse to permit such waiver, agreement or permission even with an additional charge, then the other party shall have the right to designate another insurer with a Best's Insurance Guide rating of A-XI or better who would be prepared to permit such waiver, and the first party shall use such other insurer. 7.4.2 Landlord's Waiver. As long as Landlord's casualty insurance policies include the waiver of subrogation or agreement or permission to release liability referred to in Section 7.4.1, Landlord hereby waives, for itself and those claiming through or under it, any right of recovery against Tenant, any other permitted occupant of the Premises, and of their partners, employees, agents or contractors, for any loss occasioned by fire or other insured casualty, whether or not arising from the negligence of Tenant or its employees, agents or contractors. If at any time any of Landlord's property insurance policies shall not include such or similar provisions, the waiver set forth in the foregoing sentence shall, upon notice given by Landlord to Tenant, be of no further force or effect (or, if the insurer shall not grant such waiver for all of the required parties, such waiver shall be of no force or effect only with respect to the required parties not included in such waiver). To the extent that Landlord is at any time a self-insurer with respect to loss, damage or destruction by fire or other casualty, Landlord agrees to waive any claim or right of recovery which Landlord might have against Tenant for any loss occasioned by fire or other casualty, whether or not arising from Tenant's negligence. 7.4.3 Tenants' Waiver. As long as Tenant's property insurance policies include the waiver of subrogation or agreement or permission to release liability referred to in Section 7.4.1 and provided that Landlord provides the waiver referred to in Section 7.4.2, Tenant hereby waives (and agrees to cause all other occupants of the Premises to execute and deliver to Landlord instruments waiving), for itself and those claiming through or under it any right of recovery against Landlord, the other additional insureds and any of their partners, employees, agents or contractors, and against other lessees of the TELEHOUSE Complex to the extent that the policies of such other lessees permit a similar waiver for the benefit of Tenant and such other lessee actually gives such a waiver, for any loss occasioned by fire or other insured peril, whether or not arising from the negligence of Landlord or its employees, agents or contractors. If at any time any of Tenant's property insurance policies shall not include such or similar provisions, the waiver set forth in the foregoing sentence shall, upon notice given by Tenant to Landlord, be of no further force or effect (or, if the insurer shall not grant such waiver for all of the required parties, such waiver shall be of no force or effect only with respect to the required parties not included in such waiver). To the extent that Tenant is at any time a self-insurer with respect to loss, damage or destruction by fire or other peril, Tenant agrees to waive any claim or right of recovery which Tenant might have against Landlord for any loss occasioned by fire or other peril, whether or not arising from Landlord's negligence provided that Landlord provides the waiver referred to in Section 7.4.2. 7.4.4 Limitation on Waiver. Except to the extent expressly provided in this Section 7.4, nothing contained in this Lease shall relieve either party of any liability to the other or to its insurance carriers which such party may have under law or the terms of this Lease in connection with any damage to the Building by fire or other peril. SECTION 7.5 POLICY REQUIREMENTS. Landlord and its agents and employees, the City of New York, the New York City Public Development Corporation, the Port Authority and any other Superior Lessor or any Superior Mortgagee whose name and address shall have been furnished to Tenant shall be designated as additional insureds on any insurance policy required by this Article VII. Tenant shall deliver to Landlord certificates of insurance for the 24 <PAGE> insurance coverage required by this Article VII, in form reasonably satisfactory to Landlord, issued by the insurance company or its authorized agent, within thirty (30) days of the Commencement Date. Tenant shall procure and pay for renewals of such insurance from time to time before the expiration thereof, and Tenant shall deliver to Landlord such renewal certificate(s). At Landlord's request, Tenant shall deliver certificates of insurance to additional insured parties. All policies shall be issued by companies of recognized responsibility, reasonably acceptable to Landlord, and licensed to do business in the State of New York. All policies shall provide that they cannot be cancelled or modified unless Landlord, the Port Authority and any other Superior Lessor or any Superior Mortgagee named as an additional insured are given at least thirty (30) days' prior written notice of such cancellation or modification. All insurance policies involving liability shall contain a provision that in any action or proceeding under or in connection with such policy, the insurance carrier shall not without obtaining express advance consent from the General Counsel of the Port Authority raise any defense involving in any way the immunity of the Port Authority, its Commissioners, officers, agents or employees, the governmental nature of the Port Authority, the provisions of any statutes respecting suits against the Port Authority, or the jurisdiction of the tribunal over the person of the Port Authority. Tenant shall not carry separate or additional insurance, concurrent in form or contributing in the event of any loss or damage with any insurance required to be obtained by Tenant under this Lease. Tenant may carry any insurance coverage required of it hereunder pursuant to blanket policies of insurance so long as the coverage afforded Landlord and the other additional insureds thereunder shall not be less than the coverage which would be provided by direct policies. SECTION 7.6 PREMIUM INCREASE. If, by reason of any default by Tenant under this Lease after notice and beyond any applicable grace period, or by reason of any Tenant's Work Installed in the Premises except for any work performed by Landlord pursuant to the terms hereof, including without limitation, the work referred to in Section 2.3 of this Lease, the premiums on Landlord's insurance on the Building (including without limitation rent insurance) are higher than they otherwise would be, Tenant shall correct such default, and Tenant shall reimburse Landlord, within thirty (30) days after demand, as Additional Rent, for that part of the premiums attributable to the default by Tenant or the Tenant's Work. If, due to the particular manner of Tenant's use of the Premises, any such insurance shall be cancelled by the insurance carrier, then Tenant shall cease such. use or occupancy and shall indemnify, defend and hold Landlord harmless against any loss which would have been covered by such Insurance. A schedule or statement of rates for the Building, issued by the insurance companies insuring the Building, or by a fire insurance rating organization or other similar body making rates for insurance for the Building, shall be conclusive evidence of the facts therein stated and of the several items and charges in the insurance rate then applicable to the Building. ARTICLE VIII ALTERATIONS SECTION 8.1 CONDITIONS. SECTION 8.1.1 ALTERATIONS BY TENANT. With Landlord's prior approval, which will not be unreasonably withheld, and the prior approval of the Port Authority, if such approval is required pursuant to the Ground Lease, Tenant may from time to time, at its expense, make such alterations, improvements, additions and replacements (including installation of fixtures, cables, wires) and decorations (collectively, "Alterations") in and to the Premises as Tenant may desire provided that: (a) the Alterations do not affect the outside appearance of the Building and are not visible from the outside of the Building; (b) the Alterations are non-structural and do not impair the strength or structural integrity of the Building; (c) the Alterations are to the interior of the Premises and do not affect any part of the Building outside of the Premises; (d) the Alterations do not adversely affect the proper functioning of the mechanical, electrical, sanitary and other service systems of the Building, or unreasonably increase the usage of such systems by Tenant; (e) before proceeding with any Alteration (other than decorations), Tenant shall submit to Landlord, for Landlord's reasonable approval, plans and specifications for the work to be done, and Tenant shall not proceed with such work until it obtains Landlord's approval, which shall not be unreasonably withheld; (f) Tenant shall pay to Landlord upon demand the reasonable direct, outof-pocket costs and expenses actually incurred by Landlord in reviewing Tenant's plans and specifications and inspecting the Alterations to determine whether they are being performed in accordance with the approved plans and specifications and in compliance with law, including the fees of any architect or engineer employed by Landlord for such purpose; and (g) Tenant shall comply with the rules and regulations of Landlord and the Port Authority (including applicable provisions of the Ground Lease) then 25 <PAGE> in force with respect to the making of Alterations. Tenant hereby agrees that the review and approval by Landlord of Tenant's plans and specifications for Alterations are solely for Landlord's benefit. Landlord shall have no duty toward Tenant, nor shall Landlord be deemed to have made any representation or warranty to Tenant with respect to the safety, adequacy, correctness, efficiency or compliance with law of the plans and specifications, the Alterations or their design, or any other matter regarding the Alterations. Landlord shall, at no cost or expense to Landlord, cooperate reasonably with Tenant and its contractors and subcontractors in obtaining all permits, approvals, certificates and bonds required under this Article VIII. SECTION 8.1.2 ALTERATIONS BY LANDLORD. Landlord reserves the right, at any time, to make such Alterations, in or to the Building, the TELEHOUSE Complex and the respective systems and equipment of each, as well as in or to street entrances, doors, halls, passages, elevators, escalators and stairways, and other public parts of the Building, as Landlord shall deem necessary or desirable. However, Landlord shall not exercise its rights under this Section 8.1.2 in a manner that would materially interfere with Tenant's use or access to the Premises, reduce Tenant's usable square footage, materially alter the configuration of the Premises, or in any manner effect the Tenant's ability to continue their permitted use of the Premises. SECTION 8.2 PERFORMANCE. Landlord or Tenant shall obtain all necessary governmental permits and certificates for the construction of the Alterations which either of them undertakes and for the use and occupancy of the Alterations upon completion. Tenant shall retain a reputable contractor, selected from Landlord's list of acceptable contractors and independently approved by Landlord (which approval shall not be unreasonably withheld) and by the Port Authority for specific Alterations, to perform the Alterations in compliance with the permits and certificates and applicable law. Alterations shall be diligently performed in a good and workmanlike manner, using new materials and equipment at least equal in quality and class to the better of: (a) the original installations of the Building, or (b) the prevailing building standards established by Landlord. Any Alterations by Tenant in the mechanical, electrical, sanitary, heating, ventilating, air-conditioning or other systems of the Building shall be performed only by contractors designated by Landlord. Alterations shall be performed in a manner that causes the least interference with the use of the Building by lessees and occupants and in a manner that does not interfere unreasonably with, delay or, in the case of Tenant's Alterations, impose additional expense on Landlord in the maintenance, repair or operation of the Building; and if any additional expense is incurred by Landlord as a result of any Alterations by Tenant, Tenant shall reimburse Landlord for such additional expense, within thirty (30) days after demand, as Additional Rent. Throughout the performance of Alterations by Tenant, Tenant shall carry, or cause its contractors to carry, workers' compensation insurance as required by law and general liability insurance, with completed operations endorsements, for any occurrence in or about the Building, in such coverage limits as Landlord may reasonably require, with insurers meeting the requirements of Section 7.5. Landlord and the Persons specified in Section 7.5 shall be designated as additional insureds on such insurance policies. Tenant shall furnish Landlord with evidence reasonably satisfactory to Landlord that such insurance is in effect before the commencement of Alterations and, on request of Landlord during construction, Tenant shall provide evidence reasonably satisfactory to Landlord that the insurance remains in effect. Upon completion of any Alterations, Landlord or Tenant shall obtain certificates of final approval of such Alterations required by any governmental authority and, in the case of Alterations performed by Tenant, shall furnish Landlord with copies thereof, together with the "as-built" plans and specifications therefor as approved in accordance with law and the Rules and Regulations for the Building and the Teleport. If any of Tenant's Alterations involve the removal of fixtures, equipment or other property in the Premises which are not Tenant's Property, the removed fixtures, equipment or other property shall be promptly replaced at Tenant's expense with new fixtures, equipment or other property of like utility and at least equal value, unless Landlord otherwise directs Tenant in writing. SECTION 8.3 LIENS AND VIOLATIONS. 8.3.1 Discharge of Liens and Violations. Tenant shall promptly procure the cancellation or discharge of all notices of violation arising from or otherwise connected with Alterations, or any other work, done for Tenant, or any person claiming through or under Tenant, which shall be Authority or the Building Department of the City of New York or any other public authority. Tenant shall not utilize materials in Alterations that are subject to security interests or liens. Tenant shall defend, indemnify and hold Landlord harmless from and against all liens and encumbrances or claims of liens or encumbrances filed in connection with Alterations, or any other work, labor, services or materials done for or supplied to Tenant, including security interests in any materials, fixtures or articles installed in the Premises; and against all costs, expenses and liabilities incurred in connection with any such lien or 26 <PAGE> encumbrance, or claim of lien or encumbrance, its removal or any related action or proceeding. Subject to Tenant's right to contest as set forth below, Tenant shall satisfy or discharge of record each lien or encumbrance within fifteen (15) days after it is filed. If Tenant fails to do so, Landlord shall have the right to satisfy or discharge such lien or encumbrance by payment to the claimant on whose behalf it was filed or by payment into court or to the County Clerk pursuant to the New York Lien Law. Tenant shall reimburse Landlord within thirty (30) days after demand for the costs and expenses so incurred by Landlord, as Additional Rent, and without regard for any defense or offset that Tenant may have had against the claimant. 8.3.2 Tenant's Right to Contest Liens. Notwithstanding anything to the contrary contained in this Section 8.3, Tenant shall have the right to contest in good faith and with diligence the correctness or the validity of any lien, encumbrance or claim therefor if Tenant discharges the lien of record, whether by deposit of funds into the appropriate court or with the County, Clerk or by procuring and recording a lien release bond issued by a corporation authorized to issue surety bonds in the State of New York in an amount equal to one and one-half (1.5) times the amount of the claim of lien, encumbrance or claim therefor. The bond shall meet the requirements of New York law and shall provide for payment of any sum that the claimant may recover on the claim, together with costs of suit if it recovers in the action. Nothing in this Lease contained shall be construed as a consent on the part of Landlord to subject Landlord's estate in the Premises to any lien or liability under the Lien Law of the State of New York. SECTION 8.4 LABOR CONDITIONS. In the performance of Alterations, Tenant shall not permit any Labor Condition to arise or continue at the Building or the Teleport which interferes with the progress of other construction work at the Building or the Teleport. The determinations of the Port Authority or Landlord as to whether any Labor Condition interferes with the progress of other construction work at the Teleport or the Building shall be conclusive on Tenant so long as such determinations are not arbitrary or capricious and, upon notice from the Port Authority or Landlord, Tenant shall, or shall cause its contractor to, rectify any Labor Condition specified in the notice as soon as is reasonably possible, unless failure to rectify such Labor Condition immediately will result in an emergency situation, in which event Tenant shall, or shall cause its contractor to, rectify such Labor Condition immediately. In the event of failure by Tenant or its contractor to comply with the requirements of this Section (whether or not such failure is due to Tenant's fault), the Port Authority or Landlord by notice shall have the right to suspend the Port Authority's or Landlord's permission to Tenant to proceed with any portion of the Alterations being performed, and Tenant shall thereupon immediately cease the same. Unless failure to immediately suspend construction will result in an emergency condition, the Port Authority has agreed to give, and Landlord will give, reasonable advance notice before directing a cessation of construction. When the Labor Condition shall be so settled that such interference no longer exists, the Port Authority has agreed to, or Landlord, by notice to Tenant, shall, reinstate the permission to Tenant to perform the Alterations on all the same terms and conditions as before the suspension. "Labor Condition" shall mean and include strikes, boycotts, picketing, work-stoppages, slowdowns, complaints, disputes, controversies, or any other type of labor trouble, regardless of the employer of the Person involved or their employment status, if any. SECTION 8.5 PORT AUTHORITY'S FEE. If the Port Authority shall charge any fee in connection with any Alteration to the Premises, Tenant shall pay the fee. SECTION 8.6 IMPROVEMENT FEE. Tenant shall pay to Landlord as Additional Rent in connection with any Alterations except for those performed by Landlord in connection with Tenant's initial occupancy of the Premises, Landlord's fee (the "Improvement Fee"). which shall not exceed (i) fifteen percent (15%) of the total cost of such Alteration it Landlord performs the Alteration on Tenant's behalf, and (ii) if Tenant performs the Alteration, all of Landlord's reasonable costs and expenses in connection with such Alteration. There shall be excluded from such computation the cost of furniture, furnishings, draperies, office, computer and communication equipment, painting, cabinetry, items of special decoration and telephone installation. Prior to making-any Alteration, Tenant shall submit to Landlord a statement of Tenant's contractor, estimating the total cost of such Alteration. The Improvement Fee shall be calculated on the basis of such estimate and paid in equal monthly installments during the course of the performance of the Alteration, together with the monthly installments of Base Rent. Upon completion of the Alteration, Tenant shall submit to Landlord a statement of Tenant's contractor, certifying the total cost of such Alteration. The Improvement Fee shall be adjusted, if necessary, based on the certification. Within thirty (30) days 27 <PAGE> after completion of the Alteration, Tenant shall pay to Landlord any remaining balance of the Improvement Fee. If the Improvement Fee, as adjusted, is less than the amount theretofore paid to Landlord, Landlord, within thirty (30) days after receipt of the certification, shall refund to Tenant the amount of such overpayment.

Tenant shall be entitled to receive that portion of the award which is made for any such temporary taking of the Premises attributable to any period within the Lease Term and for any damage to Tenant's Property. Landlord shall be entitled to receive that portion of the award which is made for any such temporary taking of the Premises attributable to the period after the expiration of the Lease Term or which is allocable to the Building, other than the Promises, or to the cost of restoration of the Premises or which is made for any other purpose. If any such temporary taking terminates prior to the expiration of the Lease Term, Tenant shall restore the Premises as nearly as possible to their condition prior to the taking, at Tenant's sole cost and expense; provided that Tenant shall receive the portion of the award attributable to such restoration.

This Section 17.1 shall be self-operative and no further instrument of subordination shall be required. However, in confirmation of subordination. Tenant shall promptly execute, 37 <PAGE> acknowledge and deliver any instrument that Landlord, the lessor under any such lease or the mortgagee under any such mortgage or any of their respective successors in interest may reasonably request to evidence such subordination if Tenant fails to execute, acknowledge or deliver any such instrument within ten (10) days after request therefor, such failure shall constitute a material default under this Lease. Tenant hereby irrevocably appoints Landlord as Tenant's attorney-in- fact, with full power of substitution, coupled with an interest, to execute, acknowledge and deliver any such instrument for and on behalf of Tenant in the event of such a default by Tenant,' but exercise by Landlord of its power-of attorney shall not cure the default.

If, within said reasonable period, the Port Authority or such a Superior Mortgagee or Superior Lessor gives Tenant notice of its intention to remedy the act or omission, and thereafter diligently commences the required remedial action and pursues it to completion, Tenant shall have no right to terminate this Lease on account of the act or omission. SECTION 17.4 ATTORNMENT. Any Superior Lessor or Superior Mortgagee who succeeds to the rights of Landlord under this Lease, whether through exercise of remedies in a Superior Lease or Superior Mortgage or by operation of law, is in this Section 17.4 called a "Successor Landlord". Subject to the terms of any non-disturbance agreement between Tenant and the Superior Landlord, if such Successor Landlord does not elect to treat this Lease as extinguished, upon the Successor Landlord's request, Tenant shall attorn to and recognize the Successor Landlord as Tenant's landlord under this Lease and shall promptly execute and deliver any instrument that such Successor Landlord may reasonably request to evidence the attainment. Tenant hereby irrevocably appoints Landlord or the Successor Landlord as Tenant's attorney-in-fact, coupled with an interest, to execute, acknowledge and deliver the instrument of attornment on behalf of Tenant in the event Tenant fails to do so within twenty (20) days after receipt.

SECTION 17.5 REQUIREMENTS OF SUPERIOR LESSOR OR MORTGAGEE. If any Superior Lessor or Superior Mortgagee requires any modifications of this Lease, Tenant shall, at Landlord's request, promptly execute and deliver to Landlord instruments effecting the modifications that the Superior Lessor or Superior Mortgagee requires, provided that such modifications do not adversely affect in a material respect any of Tenant's rights or Landlord's obligation, or reduce limit or modify, in a manner materially adverse to Tenant, Landlord's obligations under this Lease. SECTION 17.6 COMPLIANCE WITH GROUND LEASE. 17.6.1 Approval of Lease and Sublease By Port Authority. Notwithstanding the execution of this Lease by Landlord and Tenant, if the Port Authority shall refuse to execute and deliver a consent agreement in the form 38 <PAGE> attached to the Ground Lease as "Exhibit Z", a copy of which is attached hereto as Exhibit Z, then on the date of such refusal this Lease shall terminate and all obligations of Landlord and Tenant arising thereafter shall be discharged and released automatically.

If the default shall have been remedied, the Port Authority shall remit to Landlord any such rentals, fees, charges or other amounts it has collected and which have not been used by the Port Authority to cure the default pursuant to the terms of the Ground Lease. No change or modification to this Lease shall be binding on the Port Authority unless and until the Port Authority shall have given its written approval to such change or modification. This Lease shall terminate and expire, without notice to Tenant, no later than the day preceding the date of expiration of the Ground Lease, or on the earlier expiration date of the Lease Term, or on the effective date of any revocation of the Port Authority's consent to this Lease.

Tenant covenants and agrees to execute and deliver, at any time and from time to time, upon the request of the landlord under such Underlying Lease, any instrument which may be necessary or appropriate to evidence such attornment. Tenant further waives the provisions of any statute or rule of law now or hereafter in effect which may terminate this lease or give or purport to give Tenant any right of election to terminate this lease or to surrender possession of the premises demised hereby in the event such Underlying Lease terminates or in the event any such proceeding is brought by the landlord under such Underlying.

SECTION 19.13 STANDARDS OF LANDLORD'S CONSENT. Landlord and Tenant agree that if Tenant desires to assign this Lease or sublet all or any part of the Premises, and Landlord withholds its consent or conditions its consent and Tenant believes that Landlord did so unreasonably, Tenant may prosecute an action for declaratory relief to determine if Landlord unreasonably withheld or conditioned its consent, but Tenant waives and discharges any claims it may have against Landlord for damages arising from Landlord's withholding or conditioning its consent. In any such action, each party shall bear its own attorneys' fees. Tenant shall indemnify, defend and hold Landlord harmless from any and all liability, losses, claims, damages, costs, expenses, causes of action and proceedings involving any third party or parties (including without limitation Tenant's proposed subtenant or assignee) who claim they were damaged by Landlord's wrongful withholding or conditioning of Landlord's consent.

(hereinafter called the "Space Lessee) whose representative is Allan Leinwand WITNESSETH, that: WHEREAS, the Port Authority and the Lessee have heretofore entered into an agreement dated August 9, 1988 (which agreement, as the same has been or may hereafter be supplemented and amended, is hereinafter called the "Main Lease" covering the construction and operation of an office building or buildings at the Teleport (located in a portion of the Staten Island Industrial Park leased by the City of New York to the Port Authority and hereinafter called the "Facility"); and WHEREAS, pursuant to and in accordance with the terms of the Main Lease, the Lessee proposes as of the effective date hereof to enter ink a use and occupancy agreement with the Second Amendment to the Space Lease dated June 1st, 2000, a copy of which is attached hereto, made a part hereof and hereafter called "Second Amendment", subject to the consent of the Port Authority and the execution of a Consent Agreement by and among the Lessee, the Space Lessee and the Port Authority; NOW, THEREFORE, for and in consideration of the covenants and mutual agreements herein contained, the Port Authority, the Lessee and the Space Lessee hereby agree effective as of June 1st, 2000, as follows: 1. On the terms and conditions hereinafter set forth, the Port Authority consents to the Space Lease. 2. The Second Amendment shall terminate, without notice to the Space Lessee, on the day proceeding the date of expiration or earlier termination of the Main Lease, or on such earlier date as the Lessee and the Space Lessee may agree upon. The Space Lessee shall quit the space covered by the Second Amendment and remove its property for which it is responsible therefrom on or before the termination of the Second Amendment. 3. Neither this Consent Agreement, or anything contained herein nor the consent granted hereunder shall constitute or be deemed to constitute a consent to nor shall they create an implication that there has been consent to any enlargement or change in the rights, powers and privileges granted to the Lessee under the Main Lease, nor consent to the granting of any rights or privileges to the Space Lessee as may be provided by the Second Amendment if not granted to the Lessee under the Main Lease. The Second Amendment is an agreement between the Lessee and the Space Lessee with respect to the various matters set forth therein. Neither this Consent nor anything herein nor the consent granted hereunder shall constitute an agreement between the Port Authority and the Lessee that the provisions of the Second Amendment shall apply and pertain as between the Lessee and the Port Authority, it being understood that the terms, conditions and agreements of the Main Lease shall, in all respects, be controlling and determinative. The specific mention of or reference to the Port Authority in any part of the Second Amendment, including without limitation thereto, any mention of any consent or approval of the Port Authority now or hereafter to be obtained, shall not be or be deemed to create an inference that the Port Authority has granted its consent or approval thereto under this Consent Agreement or shall thereafter grant its consent or approval thereto or that the Port Authority's discretion pursuant to the Main Lease as to any such consents or approvals shall in any way be affected or impaired. The lack of any specific reference in any provisions of the Second Amendment to Port Authority approval, or consent shall not be deemed to imply that no such approval or consent is required and the Main Lease shall, in all respects, be controlling. 59 <PAGE> No provision of the Second Amendment, including, but not limited to, those imposing obligations on the Space Lessee with respect to laws, rules, regulations, taxes, assessments and liens shall be construed as a submission or admission by the Port Authority that the same could or does lawfully apply to the Port Authority, nor shall the existence of any provision of the Second Amendment covering actions which shall or may be undertaken by the Space Lessee or the Lessee including, but not limited to, construction on the space covered by the Second Amendment, be deemed to imply or infer that Port Authority consent or approval thereto pursuant to the Main Lease will be given or that Port Authority discretion with respect thereto will in any way be affected or impaired. 4. The Space Lessee, in its operations under or in connection with the Second Amendment and in its use of the space covered by the Second Amendment, shall be subject to the applicable terms, provisions, covenants and conditions of the Main Lease. Without in any way affecting the obligations of the Lessee under the Main Lease and under this Consent Agreement, all acts and omissions of the Space Lessee shall be deemed acts and omissions of the Lessee under the Main Lease, but notwithstanding the foregoing, the Lessee shall not be or be deemed to be default of the Main Lease to the extent that any of the foregoing shall constitute a breach thereof if, except for causes beyond the control of the Lessee, it shall have commenced to remedy said default within twenty (20) days after receipt of notice thereof from the Port Authority and continues diligently to pursue such remedy. 5. The Second Amendment shall not be changed, modified, discharged or extended except by written instrument duly executed by the parties thereto and only with the express written consent of the Port Authority. Without limiting the generality of the foregoing, the Space Lessee shall use the space covered by the Second Amendment for the following purpose and for no other purpose or purposes whatsoever: for communications related services in connection with its business. 6. If the Lessee shall at any time be in default of its obligations under the Main Lease to make payments to the Port Authority, or if there shall occur at any time an event involving insolvency, bankruptcy, arrangement or reorganization of the Lessee which under the terms of the Main Lease would constitute an event the occurrence of which grants the Port Authority the right to terminate the Main Lease and provided the same has not been cured within the time granted therefor, if any, under the Main Lease, the Space Lessee on demand of the Port Authority shall pay directly to the Port Authority any fee or other amount due to the Lessee. No such payment shall relieve the Lessee from any obligations under the Main Lease or under this Consent Agreement but all such payments shall be credited against the obligations of the Lessee and of the Space Lessee for each payment or part thereof. 7. The granting of the consent hereunder by the Port Authority shall not be or be deemed to operate as a waiver of consent to any subsequent agreement with respect to the use or occupancy of space at the Facility (by the Lessee or by the Space Lessee) or to any assignment of the Main Lease or the Second Amendment or of any rights under either of them, whether in whole or in part. 8. In the event of any substantial default by the Space Lessee under any of the provisions of this Consent Agreement and said default has not been cured within thirty (30) days after the Port Authority has served a notice of such default upon the Lessee and the Space Lessee, the Port Authority shall have the right to revoke the consent granted hereunder upon thirty (30) days' written notice to the Lessee and the Space Lessee, but no such revocation shall be deemed to affect the Main Lease and the continuance thereof, it being understood, moreover, that the foregoing shall not be deemed to affect or limit any rights of the Port Authority under the Main Lease. In the event of the revocation of the consent hereunder as hereinabove provided, the Lessee shall immediately terminate the Second Amendment. 9. Reference herein to the Space Lessee shall mean and include the Space Lessee, its officers, agents, employees and also others on the space covered by the Second Amendment or on the Facility with the consent of the Space Lessee. 10. Neither the Commissioners of the Port Authority nor any of them, nor any officer, agent or employee thereof shall be held personally liable to the Lessee or to the Space Lessee under any term or provision of this Consent Agreement or because of its execution or because of any breach or alleged breach hereof. 60 <PAGE> IN WITNESS WHEREOF, the Port Authority, the Lessee and the Space Lessee have executed these presents.
