CAPACITY AGREEMENT

This
  Capacity Agreement (the Agreement) is entered into on September, 28,
  2000 (the Effective Date) between Global Crossing Bandwidth, Inc., on
  behalf of itself and its Affiliates, as defined herein, that may provide a
  portion of the services hereunder (Global Crossing), a California
  corporation located at 90 Castilian Drive, Goleta, California 93117 and Exodus
  Communications, Inc. (collectively, Exodus or Purchaser), a
  California corporation with its principal place of business located at 2831
  Mission College Blvd., Santa Clara, CA 95054 (hereinafter, Global Crossing and
  Exodus may be referred to in the aggregate as Parties, and each
  singularly as a Party.)

PURPOSE

Exodus
  desires to purchase (1) telecommunications services in the form of dedicated
  circuit capacity from Global Crossing for the transport of Exodus
  telecommunications traffic and (2) rights with respect to international
  capacity on an indefeasible right of use basis. The Parties agree as follows:

1.   SERVICES

(a)  Global
  Crossing shall, in accordance with this Agreement, provide Exodus with
  telecommunications capacity, comprising [***] DS-0 channel miles (the Total
  Initial Channel Miles). Such capacity will include 9.953 Gbps Linear
  Wavelength Services (as such services become available) and 2.488 Gbps Linear
  Wavelength Services (the Wavelength Services) and OC-12 and OC-3 SONET
  services (the SONET Services) between the city pairs defined in Exhibit
  A attached hereto and made part hereof (City Pairs). As circuits are
  accepted, the DS-0 miles associated with such circuit will be deducted against
  the Total Initial Channel Miles. Within sixty (60) days after execution of
  this Agreement, the parties will establish procedures for auditing the Total
  Initial Channel Miles. The minimum term for all circuits shall be [***].
  Global Crossing will provide SONET Services and Wavelength Services in
  accordance with the Technical Specifications set forth in Exhibit C. Exodus
  may order additional capacity pursuant to such other exhibits as the Parties
  may from time to time execute and attach hereto (the Exhibits), upon the
  same terms as to pricing, payment arrangements and term of Agreement as set
  forth in Article 2. All capacity under the Exhibits is collectively referred
  to as the Services. All rights of ownership in the Global Crossing
  network, the fiber and the related electronics used in providing the Services
  remain with Global Crossing. This Agreement is not intended to lease or sell
  any interest in the Global Crossing network to Exodus.

(b)  For
  all 9.953 Gbps Linear Wavelength Services, 2.488 Gbps Linear Wavelength
  Services, OC-12 and OC-3 SONET Services between any City Pair, the conversion
  rates as set forth in the Mileage Conversion Matrix in Exhibit D shall apply.

(c)  During
  the Initial Term of this Agreement (as defined in Section 2 below), Exodus
  shall have the right to replace any previously installed circuit between any
  City Pair with a circuit between any other City Pair, subject to availability,
  at no additional charge except as set forth below. If the new circuit is for a
  greater number of DS-0 channel miles, upon Acceptance (as defined below) of
  the new circuit, the higher number of DS-0 channel miles will begin to be
  deducted against the Total Initial Channel Miles. If the new circuit is for a
  lower number of DS-0 channel miles, and the existing circuit has been in
  service less than [***], the number of DS-0 miles associated with the existing
  circuit will continue to be deducted from the Total Initial Channel Miles for
  the remainder of such [***] period in addition to the applicable deduction for
  the new circuit. Notwithstanding the foregoing, in no event may the capacity
  level for any physical route exceed the equivalent of (2) 9.953 Gbps circuits,
  without Global Crossings consent, which shall not unreasonably be withheld.
  If Exodus orders additional capacity under this Agreement then for each
  subsequent billion DS-0 channel miles ordered, the capacity level for any
  physical route will not exceed the equivalent of (2) 9.953 Gbps circuits,
  without Global Crossings consent, such consent not to be unreasonably
  withheld.

(d)  Exodus
  shall have the right at any time to replace any previously installed circuit
  between any City Pair with a circuit of greater DS-0 miles between the same
  City Pair at no additional charge except for as set forth below. Upon
  Acceptance of the new circuit, the increased number of DS-0 miles will begin
  to be deducted against the Total Initial Miles. Notwithstanding the foregoing,
  in no event may the capacity level for any physical route exceed the
  equivalent of (2) 9.953 Gbps circuits, without Global Crossings consent,
  which shall not unreasonably be withheld. If Exodus orders additional capacity
  under this Agreement then for each subsequent billion DS-0

channel miles ordered, the capacity level for
  any physical route will not exceed the equivalent of (2) 9.953 Gbps circuits,
  without Global Crossings consent, such consent not to be unreasonably
  withheld.

(e)  Global
  Crossing will deliver and Exodus will take the Services in accordance with the
  Take Down Schedule set forth in Exhibit D.

(f)  Colocation
  will be provided in accordance with Exhibit B.

(g)  The
  parties hereby agree to the provisions of Exhibit F which sets out the terms
  and conditions upon which Global Crossing shall grant and Exodus shall acquire
  rights to certain international capacity on an indefeasible right of use
  basis. Save for this provision and save where expressly stated otherwise in
  Exhibit F the provisions of this Agreement will not apply to Exhibit F.

2.  TERM OF THE AGREEMENT:

This
  Agreement shall, subject to the termination provisions set out in Section 4 of
  this Agreement, remain in effect for a period of ten (10) years from the date
  that the first circuit is made available to Exodus under this Agreement (Initial
  Term). Within six months of the end of the Initial Term the parties, will
  negotiate in good faith to determine whether and upon what terms this
  Agreement will renew for an additional term. If the parties fail to reach
  agreement as to the terms of any renewal, this Agreement will terminate at the
  end of the Initial Term.

3.  BILLING AND PAYMENT;
  SEGMENT/CIRCUIT ACCEPTANCE

(a)  Exodus
  shall pay Global Crossing $ [***] as a non-recurring,
  non-refundable charge (the Initial Total Non-Recurring Charge) for the
  Total Initial Channel Miles. Exodus shall pay Global Crossing the Initial
  Total Non-Recurring Charge by wire transfer to the designated Global Crossing
  account on 29 September 2000. Exodus is also liable for applicable taxes and
  governmental assessments with respect to its use or purchase of the Services.
  Notwithstanding the foregoing, Exodus shall have no obligation to pay or be
  liable to pay any taxes on the gross income or net receipts of Global Crossing
  levied or assessed on or related to any payments made by Exodus to Global
  Crossing under this Agreement.

(b)  Payments
  to Global Crossing shall be made via wire transfer in immediately available
  U.S. funds to the following account (subject to change by Global Crossing):



(c)  Acceptance
  of a segment/circuit shall be determined as follows; Global Crossing will
  provide Exodus with notice (including segment test results) when a segment is
  ready from Global Crossing POP to POP and , if such segment/circuit consists
  of 9.953 Gbps Linear Wavelength Services, Global Crossing will supply Exodus
  with the technical specifications relating thereto which will be deemed to
  form part of Exhibit C for the purposes of Acceptance of that
  segment/circuit. Exodus shall have (5) five business days to confirm that the
  segment meets the technical specifications set out in Exhibit C. If Exodus
  does not accept or provide detailed written documentation as to any failure to
  comply with the technical specifications within said five business day period,
  then the segment/circuit shall be deemed accepted. In the event of any good
  faith rejection by Exodus, Global Crossing shall take such action as
  reasonably necessary, and as expeditiously as practicable, to correct or cure
  such defect or failure in accordance with the applicable specifications set
  forth in Exhibit C.

(d)  Exodus
  will from time to time submit circuit orders for additional telecommunications
  capacity to be delivered by Global Crossing. Global Crossing will be bound to
  deliver such capacity in accordance with the delivery periods set out in
  Exhibit D provided the relevant circuit(s) are included in Exodus forecast
  to be provided pursuant to Exhibit D. In the event of failure by Global
  Crossing to provide any such capacity Exodus sole remedies shall be as set
  out in Exhibit E.

(e)  Payment
  terms for any invoices hereunder (other than the Initial Total Non-Recurring
  Charge) are net 45 days from the invoice date. Any invoice not paid by its due
  date shall bear late payment fees at the rate of 1% per month (or such lower
  amount as maybe required by law) until paid. If Exodus is delinquent in
  payment of an undisputed invoice and does not cure such delinquency within
  (15) fifteen days of receipt of written notice from Global Crossing, Global
  Crossing may terminate this Agreement and deny Purchaser, its personnel and
  its third party vendors access to the colocation premises until paid. If
  Exodus disputes any invoice it will notify Global Crossing of such dispute and
  provided Exodus provides sufficient detail for investigation of the dispute,
  Global Crossing will use all reasonable efforts to resolve and communicate its
  resolution of the dispute to Exodus within thirty (30) business days of its
  receipt of notice of such dispute. Notwithstanding the foregoing, no interest
  shall accrue on any payment that is disputed in good faith by Exodus, unless
  the dispute is resolved in Global Crossings favor.

(f)  Except
  as otherwise specifically provided in this Agreement or an Exhibit, Exodus is
  responsible for ordering all facilities and equipment necessary for its
  interconnection to Global Crossings network for use of the Services. Global
  Crossing agrees to provide Exodus or Exodus - selected local carrier access to
  Global Crossings demarcation and to use all reasonable endeavors to
  cooperate with Exodus or its selected local carrier to interconnect with the
  Global Crossing Network. Exodus shall be liable for all costs and expenses of
  such interconnection, including without limitation, the installation, testing,
  maintenance and operation of equipment and facilities.

  such breach, the other Party may take such actions as it determines, in its
  sole discretion, to correct the default, and pursue any legal remedies it may
  have under applicable law or principles or equity, including specific
  performance.

(c)  Exodus
  exclusive remedies for any failure by Global Crossing to deliver the capacity
  in respect of an accepted circuit order in accordance to this Agreement or on
  time are contained in the Service Level Agreement as set forth in Exhibit E.

COLOCATION SERVICE

All
  Colocation facilities are pending Global Crossings Engineering approval
  based upon the information provided to Global Crossing by Exodus in the
  Colocation Service Inquiry From. Any approved facilities shall be presented to
  Exodus as an amendment pursuant to Section 1.A. below.

1.  LICENSE:

A.  Global
  Crossing hereby grants Exodus a license to occupy certain designated space
  (the Space) within a designated Global Crossing premise (the Facility).
  Separate Colocation Schedules may be attached hereto from time to time
  covering for each separate site where Colocation will be established. All
  Colocation Schedules, upon their execution by both Parties, shall be
  incorporated herein and shall become a part hereof. By executing a Colocation
  Schedule, Exodus accepts the Space on an AS-IS, WHERE IS basis. Exodus
  may only use the Space to install, maintain, monitor, operate, replace, repair
  and remove certain of its telecommunications equipment (the Equipment)
  as specified on the Colocation Schedule.

B.  Exodus
  acknowledges that it has been granted only a license to occupy the Space and
  that it has no real property interests therein. Exodus shall not utilize the
  Facility for any unlawful purposes, assign, mortgage, sublease, encumber or
  otherwise transfer any Space or license granted hereunder. Any attempt by
  Exodus to encumber the Space or permit the use or occupancy by anyone other
  than Exodus shall be void.

C.  Exodus
  may utilize the Space and the Equipment to receive services from third party
  providers, other than for intercity domestic backbone capacity. Global
  Crossing will permit access to the Space by the third party providers in
  accordance with the terms herein.

2.  TERM AND TERMINATION:

A.  The
  term of a license shall be as set forth in the applicable Colocation Schedule
  and shall commence on the first day the Space is made available by Global
  Crossing (the Commencement Date), but shall be immediately terminable by
  Global Crossing upon the termination, expiration or cancellation for any
  reason of (i) any underlying agreement between Global Crossing and any other
  party involving Global Crossings continued use of the Facility, or (ii)
  this Agreement. Following the expiration of the license term as set forth in
  the Colocation Schedule for a Space, Exoduss license shall automatically
  renew on a month to month basis in accordance with the same terms and
  conditions specified herein, unless terminated by either Exodus or Global
  Crossing upon sixty (60) days prior written notice.

B.  Global
  Crossing shall not be liable to Exodus in any way as a result of Global
  Crossings failure (for any reason) to tender possession of the Space to
  Exodus on or before the commencement date listed in the Colocation Schedule.
  Any delay in tendering possession of the Space to Exodus for any reason other
  than the acts or omissions of Exodus shall relieve Exodus of its obligation to
  pay the monthly recurring charges (MRC) set forth in the Colocation Schedule
  until possession of the Space is delivered to Exodus.

3.  CHARGES, FEES and TAXES:

A.  MRCs
  shall be payable in advance and without notice or demand and without
  abatement, deduction, counterclaim or setoff commencing on the first day the
  Space is made available by Global Crossing and on the first day of each
  calendar month thereafter. Installation and non-recurring charges are due when
  invoiced. MRCs shall be prorated for partial months. The MRCs may be increased
  from time to time during the term of the license by reason of (i) any
  increases payable by Global Crossing to its landlord(s) under the lease for
  the Facility or Rights of Way in which the Space is located; (ii) any
  increases incurred by Global Crossing in any of the services to the Facility
  procured by Global Crossing directly from the provider thereof; and (iii) any
  increases in real property taxes assessed against the Facility which Global
  Crossing is liable to pay. Exoduss share of any such increases shall be
  pro-rated based on the number of innerduct linear feet in the Space as a
  percentage of the total number of innerduct linear feet in the Facility.

B.  In
  addition, Exodus shall be fully responsible for the prompt payment of all
  federal, state or local taxes, however denominated, based on or calculated
  with respect to the amounts payable by Exodus (including but not limited to
  sales/use, rental and gross receipts taxes or surcharges) and all taxes
  (including, but not limited to

---

franchise, income and miscellaneous taxes)
  which are the liabilities of Exodus under (i) appropriate standard industry
  practices (including telecommunications, fiber optic and rental industries),
  (ii) applicable law and (iii) as otherwise agreed at any time between Exodus
  and Global Crossing; provided, however, the taxes on Global Crossings
  income and property shall be the sole responsibility of Global Crossing.

4.  MAKE-READY:

If
  applicable, Exodus shall pay Global Crossing the amount set forth in each
  Colocation Schedule for the cost of engineering or improvements to the Space
  required to be made by Global Crossing in order to accommodate Exoduss
  Colocation into the Space (the Make-Ready Fee). The Make-Ready Fee shall
  be payable to Global Crossing upon Exoduss execution of the Colocation
  Schedule for the Space. Title to such improvements shall remain vested in
  Global Crossing.

5.  MAINTENANCE:

A.  Global
  Crossing shall be responsible for maintenance of the Facility and the Space.
  Exodus shall not make any alterations, changes, additions or improvements to
  either the Facility or the Space without Global Crossings prior written
  consent. Exodus agrees to maintain and repair all of its Equipment

  be free from any disruptions and Global Crossing shall not be liable therefor.
  Global Crossings entire liability for any such disruptions, or any other
  matter giving rise to a claim with respect to the Space or Facility, shall not
  exceed in any case the MRCs paid by Exodus for the month in which such
  disruption or other matter occurred.

8.  DAMAGE TO FACILITY:

If
  fire or other casualty damages the Facility in which the Space is located,
  Global Crossing shall give immediate notice to Exodus of such damage. If
  Global Crossings landlord or Global Crossing exercises an option to
  terminate the lease therefor due to such damage or Global Crossings
  landlord or Global Crossing decides not to rebuild the Facility in which the
  Space is located, this Agreement shall terminate as of the date of such
  exercise or decision as to the affected Space and the MRC paid by Exodus shall
  be modified accordingly. If neither the landlord of the affected Facility nor
  Global Crossing exercises the right to terminate or not to rebuild, the
  landlord or Global Crossing, as applicable, shall repair the Facility to
  substantially the same condition it was in prior to the damage, completing the
  same with reasonable speed. In the event that such repairs are not completed
  within a reasonable time, Exodus shall thereupon have the option to terminate
  this Agreement with respect to the affected Space, such option shall be the
  sole remedy available to Exodus against Global Crossing hereunder relating to
  such failure. If the Space or any portion thereof shall be rendered unusable
  by Exodus by reason of such damage, the MRC for such Space shall
  proportionately abate for the period from the date of such damage to the date
  when such damage shall have been repaired for the portion of the Space
  rendered unusable.

  SONET deployed in a four fiber, Bi-directional Line Switched Ring (BLSR),
  conforming to Telcordia GR-253-Core SONET Transport Systems Common Generic
  Criteria (Dec. 1997) or SONET (defined as a point-to-point service which
  utilizes SONET equipment provided by Global Crossing to furnish two working
  (transmit and receive) channels and two protect channels (transmit and
  receive) between the end points of the Route. Private Line Services will be
  provided by using SONET over a Dense Wavelength Division Mulitplexor (DWDM)
  system, directly over a DWDM system, or directly over fiber.

Performance
  Standards and Transmission Specifications for Private Line Service(s) provided
  on Suppliers network under this Agreement are [***]% available seconds per
  year.

II.  WAVELENGTH:

A.  Exodus
  acknowledges that (i) the circuits used for the Wavelength Services are not
  protected by a restoration protocol within or external to the SONET frame
  structure, (ii) Global Crossing will not provide Wavelength Services using
  conventional SONET TDM add/drop multiplexers using a BLSR or UPSR or linear
  restoration protocol within or external to the SONET frame structure, and
  (iii) the interoperability of the individual circuits is dependent upon the
  joint interconnection of the interface between Global Crossings WDM system
  and Exoduss source systems and facilities. Exoduss source systems will
  operate within the conventional 1310nm and 1550nm passbands, using Short
  Reach, Intermediate Reach, or Long Reach optic, as defined in Telcordia
  GR-253-CORE. Except with Exoduss prior written consent, Global Crossing
  will provide the Wavelength Services solely over Global Crossings
  facilities-based TDM / WDM network and fiber, equipment or other WDM service(s)
  owned or controlled by Global Crossing and its Affiliates.

B.  The
  Wavelength Services will be configured as follows:

(i)  WDM
  Transmission System: WDM transmission equipment for each unprotected OC-48
  (2.488Gb/s) channel, such as WDM Terminals, in-line amplifiers, regenerators
  and optical layer cross-connect equipment necessary to provide the Wavelength
  Services; and

(ii)  OC-48
  (2.488Gb/s) TDM equipment used in conjunction with the WDM system: OC-48
  transparent TDM transmission equipment for each unprotected OC-48 channels
  capable of use on each route. Equipment such as WDM transponders, regenerators
  and wavelength converters to provision OC-48 circuits. Exoduss equipment
  may be connected through collocated equipment at facilities where both Global
  Crossing and Exodus have equipment or in a mid-span optical meet.

(iii)  At
  each of the end-point points of presence (POPs), Exodus will be
  responsible for providing all equipment necessary to interconnect with the
  Global Crossing Network. All Exodus equipment will be and remain the property
  of Exodus, except where Exodus fails to remove such equipment within thirty
  (30) days after the termination of the agreement for Optical Wavelength
  Services to or from a city, in which case, Global Crossing may deem such
  equipment in that city as abandoned, and may remove, store, or dispose of such
  equipment in its sole discretion. At each of the end-point POPs, the point of
  demarcation and connecting point between the Global Crossing network and any
  Exodus equipment will be the fiber termination panel provided by Global
  Crossing. Global Crossing will cooperate with Exoduss installation of
  fiber, cable and fiber termination equipment within POPs, including but not
  limited to providing Exodus (including its representatives and contractors),
  all necessary access to the end-point POPs at reasonable times and in a
  reasonable manner following reasonable advance notice consistent with the
  access that it may provide to other similarly situated customers whose
  presence may be permitted to collocate at its POPs; provided however, that
  with seven (7) days prior written notice, Global Crossing will provide Exodus
  with accompanied access at any time; and provided further, however, that in
  the event of an emergency, Global Crossing will exercise commercially
  reasonable efforts to provide accompanied access at any time of the day upon
  one (1) hours notice (such notice being intended for Global Crossing to
  ensure that an escort is available). Global Crossing will disclose to Exodus
  the physical routes that the unprotected OC-48 circuits will use between the
  POPs within 2 business day after receipt of an approved ASR. Should Exodus
  desire an

alternate route, Global Crossing will determine
  availability and provide revised pricing, if necessary, for such alternative
  route.

(iv)  Global
  Crossing will transmit all SONET overhead transparently between Exodus POPs.
  Global Crossing will not alter any such overhead information. Global Crossing
  will not have any SONET line or section terminating equipment within its
  network.

C.  Performance
  Standards and Transmission Specifications for the Wavelength Services provided
  on Global Crossings network under this Agreement are set forth below:

(i)  Digital
  Frame Service Rates. Service will consist of DWDM optical transmission for
  OC-48 line rates of 2.5 Gb/s, using transponders, optical couplers, optical
  layer amplifiers and 3R regenerators and or a multiplexed OC48 using a 10 Gb/s
  transparent multi-plexor. Service will be provided in unprotected linear
  fashion. All restoration protocols, if used for the circuits, will be
  implemented and operated by Exodus. Exoduss wavelengths will be part of a
  multi-wavelength DWDM transmission system carrying wavelengths for other
  customers and Global Crossings own circuits.

(ii)  Fiber
  patch cords and optical attenuators used on receivers will be the
  responsibility of the owner of the equipment to ensure that optical signal
  levels are within specification for the owners equipment. The optical
  interface at these points requires Exodus and Global Crossing OC-48 optics
  capable of accepting Short Reach, Intermediate Reach, and Long Reach OC-48
  frame signals as defined in Telcordia Document GR-253-CORE, Issue 2, Rev 1,
  dated 12/97. The appropriate type of optics for the application will depend on
  the optical link engineering conducted jointly by Global Crossing and Exodus
  on an individual case basis.

(iii)  Optical
  Translation. Global Crossing shall furnish and operate at its POPs all
  DWDM equipment necessary to generate the precision optical wavelengths
  necessary for the optically multiplexed system. The optical interface at the
  fiber patch panel or fiber frame shall require Exodus and Global Crossing
  optics capable of accepting Short Reach, Intermediate Reach and Long Reach
  OC-48 frame signals as defined in Telcordia Document GR-253-CORe, Issue 2, Rev
  1, 12/97. The appropriate type of optics for the application will depend on
  the optical link engineering conducted jointly by Global Crossing and Exodus
  on an individual case basis. Adaptation of Global Crossing DWDM equipment to
  provide intermediate reach and long reach signals per the above Telcordia spec
  will be considered on an individual case basis.

(iv)  Equipment
  Performance Specifications. Global Crossings OC-48 optical channels
  shall be designed and maintained per manufacturers specifications for power
  and environmental requirements. All of Global Crossings OC-48 circuits must
  operate with a measured BER of [***] or less.

EXHIBIT E

SERVICE LEVEL AGREEMENT

I.  DELIVERY REMEDIES:

A.  In
    the event Global Crossing fails to provision any circuit within the mutually
    agreed delivery date after accepting the relevant circuit order, Exodus
    sole remedy shall be to receive the following credits towards the Total
    Initial Channel Miles:







B.  Notwithstanding
    the foregoing clause A and notwithstanding any Force Majeure Events, in the
    event Global Crossing fails to provision a Circuit within [***] days after
    negotiated due date of the relevant Circuit Order, Exodus sole remedy
    shall be to, at its election, keep such Circuit and receive the [***] credit
    described in clause A(iii) above or [***] with respect to such Circuit and
    [***]. If Exodus [***], Global Crossing shall have no further liability or
    obligation to Exodus with respect to such Circuit Order, other than to so
    provide all remedy with respect to such Circuit.

C.  Every
    two weeks, Global Crossing will provide Exodus a status report of confirmed
    orders, and Exodus will provide Global Crossing [***] of circuits to be
    ordered. In the event that Global Crossing informs Exodus, [***] days prior
    to the agreed upon delivery date for any circuit, that such circuit will be
    more than [***], Exodus will have [***]. On notification to Exodus of the
    delay Global Crossing will give Exodus a revised delivery date (the Revised
    Date). If Exodus does [***] shall apply to that circuit unless the
    circuit is delivered after the Revised Date in which case the remedies set
    out in 1A above will apply.

II.  SERVICE LEVELS:

A.  Global
    Crossing will provide Exodus with a [***]% service availability guarantee on
    its wavelength services and [***]% on its protected private line services.
    Service availability is calculated from the ingress of the Global Crossings
    network to the egress of the Global Crossings network.

B.  The
    network availability measurement is equal to the total number of minutes in
    a calendar month during which customer network components are available,
    divided by the total number of minutes in a calendar month (Network
    Availability Time) and expressed as a percentage. Network Availability
    Time is calculated on a monthly basis for each customers network. The
    availability measurements are based on ITU-T Recommendation M.2100.

C.  A
    Service Outage is defined as a period during which there is a break in
    transmission, either identified by the Global Crossings Network
    Operations analyst or by Exodus. The start of the break is signaled by the
    first ten consecutively severely erred seconds (SESs), and the end is
    signaled by the first of ten consecutive non-SESs. A SES is a second with a
    bit error ratio of greater than or equal to 1 in 1000. Service
    unavailability does not include SESs associated with Scheduled Maintenance
    events, Customer-caused SESs, or SESs caused by companies other than Global
    Crossing.

III.  MEAN TIME TO REPAIR (MTTR):

A.  Global
    Crossing will guarantee a MTTR objective of [***] per trouble report, 7 x
    24. A Trouble Ticket will be created and completed for each outage. The MTTR
    calculation will be computed based on a summary of all monthly tickets.

B.  The
    time will be measured by time that any portion of Global Crossings
    network was not available. Time will be measured in minutes, as a monthly
    average of all troubles.



[***] Certain information on this page has
    been omitted and filed separately with the Securities and Exchange
    Commission. Confidential treatment has been requested with respect to the
    omitted portions.

---

C.  Time
    will be counted from the network alarm generation (at the point of failure)
    or trouble ticket creation and end at the latter of alarm condition
    clearance or Exodus notification to Global Crossing. The total network down
    time is divided by the number of documented trouble reports, to calculate
    the average.

D.  Credits
    for Service Outages will be applied based on the applicable number of DS-0
    miles for the affected circuit. Credits for outages will apply on a per
    Service Outage basis as follows:





E.  MTTR
    is calculated on a monthly basis and is reported as the average repair
    duration in hours of all trouble tickets within the monthly reporting
    period.

IV.  MEAN TIME TO RESPOND:

A.  Global
    Crossing will meet a Mean Time to Respond commitment of [***] per trouble
    report on a 7 x 24 basis at all locations. The start time (alarm generation
    or trouble ticket creation) and response end-time (when Exodus is contacted)
    will be added to every trouble ticket.

B.  Mean
    Time to Respond will be calculated on a monthly basis and is reported as the
    average duration in minutes to contact Exodus after the initial alarm or
    trouble report logging.

V.  BIT ERROR RATE (BER):

Global
    Crossing, as a minimum, will perform at a BER of less than [***].

IRU AGREEMENT

Global
    Crossing USA, Inc (GC USA) and Exodus entered into a capacity purchase
    agreement on August 27, 1999 (the CPA) pursuant to which Exodus agreed
    to acquire and GC USA agreed to grant rights with respect to Capacity on an
    indefeasible right of use basis. The CPA provided that purchases of
    Additional Committed Capacity would be evidenced by the parties to the CPA
    executing Schedule 2A in the form set out in the CPA. Schedule 2A is
    attached to this Exhibit F and sets out details of the Additional Committed
    Capacity to be purchased by Exodus from Global Crossing or its Affiliates.

Exodus
    and Global Crossing agree that the terms of the CPA shall apply to the
    purchase of the Additional Committed Capacity save as set out in this
    Exhibit F and Schedule 2A.

References
    in the CPA to the Grantor shall be deemed to be references to Global
    Crossing or the relevant Global Crossing Affiliate which is granting the
    rights in the Additional Committed Capacity and capitalized words and
    phrases used in this Exhibit F shall, save where otherwise defined in this
    Exhibit F, or in the capacity agreement to which this Exhibit is attached
    (the Agreement) have the meanings set out in the CPA.

In
    the event of any conflict between the terms of the CPA and this Exhibit F
    (including Schedule 2A) the terms of this Exhibit F shall prevail.

Global
    Crossing and Exodus agree as follows:

1.  Term. The term of
    the IRU granted to Exodus hereunder in respect to each Traffic Connection
    shall begin on the Activation Date of the relevant Traffic Connection and
    shall terminate on the tenth anniversary thereof. Section 12(c) of the CPA
    shall not apply to the Additional Committed Capacity.

2.  Initial Payment.On
    29 September, 2000 Exodus shall pay $[***], being the Purchase Price for the
    Additional Committed Capacity, to the Global Crossing Account details of
    which are set out in Section 3A of the agreement to which this Exhibit F is
    attached, in immediately available Dollars. The Purchase Price shall be
    non-refundable.

3.  Service Level Agreement.

(a)  Exodus
    shall be entitled to a credit equal to [***] months Initial Annual
    Maintenance Cost Payment for the affected Traffic Connection if the Actual
    Availability Date for that Traffic Connection has not occurred by the date
    which is [***] days after the later of the Anticipated Availability Date for
    that Capacity and the Requested Activation Date. If the Actual Availability
    Date occurs between [***] and [***] days following the later of the
    Anticipated Availability Date and the Requested Activation Date of a Traffic
    Connection a further credit of an amount equal to an additional [***] months
    Initial Annual Maintenance Payment for the affected Traffic Connection will
    be credited towards Exodus Initial Annual Maintenance Payment for that
    Traffic Connection.

(b)  Notwithstanding
    the foregoing if the Actual Availability Date for any Traffic Connection has
    not occurred by the later of the Delayed Availability Date (which for these
    purposes shall be the date which is [***] days from the Anticipated
    Availability Date of the relevant Traffic Connection) and the Requested
    Activation Date, then Exodus obligation to purchase that Traffic
    Connection shall terminate (unless Exodus requests an extension of time).
    The penalties specified in paragraph 3(a) above shall not apply in these
    circumstances. That portion of the Purchase Price previously received from
    Exodus in respect of the relevant Traffic Connection shall be retained by
    Global Crossing but Exodus shall be entitled to a credit (the Credit)
    equal to the amount of the Purchase Price previously received from Exodus
    which relates to such Traffic Connection. The Credit may be applied towards
    any future purchase of capacity by Exodus on the Global Crossing Network.

(c)  Global
    Crossing will grant to Exodus a credit towards the Initial Maintenance Cost
    Payments (a Maintenance Credit) in the event of an Outage of the
    Additional Committed Capacity. An Outage is defined for these purposes as
    sustained loss of service of [***] consecutive minutes or more due to the
    failure of Global Crossing to make the relevant Additional Committed
    Capacity available during that period. An Outage will be evidenced by
    customer reported trouble tickets each month, as time stamped by the Global
    Crossing trouble ticketing system. An Outage will not include outage time
    which is a result of deactivation of the Global Crossing

Network in the circumstances described in
    section 7(a)(iii) of the CPA or as a result of any scheduled maintenance
    agreed between Global Crossing and Exodus.

Exodus
    shall be entitled to a Maintenance Credit equal to [***]% of the Quarterly
    Initial Maintenance Cost Payment relating to the circuit which has suffered
    the Outage for each hour of outage. The maximum Maintenance Credit
    applicable in any [***] month period shall be an amount equal to [***]
    months Initial Maintenance Cost Payment for the relevant circuit.

[***]

(d)  Exodus
    shall not be entitled to any rights, remedies or damages whatsoever for the
    delay or non-occurrence of any Actual Availability Date other than as set
    out in this paragraph 3. Section 2(d) of the CPA shall not apply to this
    Exhibit F.

4.  Capacity to Vienna.
    The availability of the Additional Committed Capacity between Berlin, Vienna
    and Munich (the Vienna Circuit) is subject to board approval by Global
    Crossing. If such approval is not obtained by 31 October 2000 the parties
    obligations in respect of the Vienna Circuit will cease and this Exhibit F
    will cease to have any further effect in respect of the Vienna Circuit. The
    portion of the Purchase Price relating to the Vienna Circuit shall be
    retained by Global Crossing and will be credited towards any future purchase
    of Capacity by Exodus on the Global Crossing Network.

5.  Early Activation.
    Exodus may, at any time following the date of the Agreement, serve notice to
    amend the Requested Activation Date of any of the Additional Committed
    Capacity to an earlier date than that set out in Schedule 2A. Global
    Crossing may meet such amended Requested Activation Date if the relevant
    Additional Committed Capacity is available but its obligations under this
    Exhibit F shall be unaffected.

6.  Local Loops.
    Global Crossing will, when requested by Exodus, order and provision local
    loops on its behalf. The terms and conditions relating to such local loops
    will be set out in a separate Premise Access Service Agreement entered into
    between the parties.

7.  Collocation.
    Global Crossing will, when requested by Exodus and subject to availability,
    offer collocation to Exodus. The parties will enter into a separate
    collocation agreements in respect of each collocation space.

8.  Los Angeles to Sydney.Global Crossing intends to provide the Additional Committed Capacity
    between Los Angeles and Sydney on the Southern Cross Network. Global
    Crossing will allow Exodus to drop/insert in Hawaii if Global Crossing has
    the right to do so under the rights obtained by it in respect of its use of
    that network and subject to payment by Exodus of an amount equal to the cost
    to Global Crossing of it making such drop/insert available to Exodus.

9.  Option to Purchase London
    to Dublin Capacity.Exodus shall have the option to cancel its
    commitment to purchase 1 STM-1 between the Global Crossing POPs in London
    and Dublin (the Dublin Circuit) prior to activation of the Dublin
    Circuit by giving notice in writing to Global Crossing that it wishes to
    cancel such circuit. If Exodus does cancel this commitment, Global Crossing
    shall be entitled to retain the Purchase Price of the Dublin Circuit and
    Exodus shall be entitled to a credit equal to such Purchase Price to be
    applied towards any future purchase of Capacity by Exodus on the Global
