                      mediaXtranet(SM) Services Agreement
                         Standard Terms and Conditions

1. SERVICE ORDERS.

      a. All Services shall be requested on Vyvx's Service Order forms in effect
from time to time or on Customer's forms which have been previously accepted in
writing by Vyvx ("Service Order(s)"). Service Orders shall be transmitted and
processed in accordance with the terms and conditions of this Agreement as well
as any procedures set out in the applicable Service Schedule for a specific
Service. Vyvx shall accept any Service Order under this Agreement that complies
with the terms and conditions set forth herein, subject to availability and
credit approval at the time Customer places such Service Order.

      b. A Service Order is deemed accepted (subject to availability) by Vyvx
when Vyvx transmits an electronic Order Confirmation Document ("OCD") to
Customer indicating that Customer's order is being processed by Vyvx.

      c. When a Service Order is placed, Customer will designate: (i) a
requested start date ("Requested Start Date") for the Service; (ii) the desired
term of the Service; and (iii) any other information necessary to enable Vyvx to
provide the Service. Vyvx will make reasonable efforts to meet Customer's
Requested Start Date. In the event that Vyvx is unable to meet Customer's
Requested Start Date, Vyvx will notify Customer of the date when Vyvx believes
the Service will be available and Customer's Requested Start Date will be
changed to reflect the number of days of delay or advance, as appropriate.
Failure of Vyvx to deliver by Customer's Requested Start Date shall not
constitute a default under this Agreement, and Vyvx shall not be liable to pay
to Customer any penalties or damages for Vyvx's failure to meet Customer's
Requested Start Date.

      d. Any terms or conditions contained in Customer's acknowledgement or
Service Order or elsewhere which conflict with, or are different from, the terms
and conditions in this Agreement are hereby objected to by Vyvx and shall not
constitute part of this Agreement.

      e. Vyvx will issue to Customer an electronic notice that Service is
available ("Turn Up Acknowledgement" or "TUA"). The TUA will indicate that all
the relevant Service ordered through Vyvx has been tested by Vyvx and that the
Vyvx's Service meets or exceeds the Technical Specifications set forth in the
relevant Service Schedule. The TUA will also set forth the date Customer's
Service was available for use by Customer and upon which Vyvx shall commence
charging for the Service ("Effective Billing Date").

      f. Customer shall be deemed to have accepted Service, and Vyvx shall begin
billing for the Service as of the Effective Billing Date, provided that, if
Customer notifies Vyvx in writing within three (3) business days of the
Effective Billing Date that Vyvx's Service is in material non-compliance with
the applicable Technical Specifications and if, upon investigation, such
material non-compliance is due solely to Vyvx fault, then Vyvx shall correct the
non-compliance and make the appropriate adjustment to Customer's billings under
this Agreement. The occurrence of any such non-compliance shall not constitute a
default under this Agreement, and Vyvx shall not be liable to pay to Customer
any penalties or damages resulting from any such non-compliance. Charges for
Service begin accruing upon Circuit Effective Billing Date, regardless of
whether Customer is actually using the Services, or is ready to test and accept
the Services.

2. PAYMENT AND LATE PAYMENT TERMS.

      a. Service Charge. All fees and charges associated with the Services,
which may include non-recurring charges and monthly recurring charges (the
"Service Charge"), shall be set forth in each particular Service Schedule. The
monthly recurring and some non-recurring Service Charges shall be invoiced
monthly in advance. Other non-recurring Service Charges will be invoiced in
arrears. All amounts stated on each monthly invoice are due and payable in U.S.
dollars before the first day of the month in which Services are to be provided
for those Service Charges invoiced in advance and otherwise within thirty (30)
days of the date of the invoice for those Service Charges billed in arrears
("Due Date"). Customer agrees to remit payment via Automated Clearinghouse
("ACH") or wire transfer to Williams Communications, LLC, in care of Bank One,
Chicago, Illinois, ABA #071000013, Account #52-87235 or such other bank or
account as Vyvx may in writing direct Customer to remit payment pursuant to the
notice provisions of this Agreement. In the event Customer fails to make full
payment of undisputed amounts by the Due Date, Customer shall also pay a late
fee in the amount of the lesser of (i) one and one-half percent (1 1/2 %) per
month or (ii) the maximum lawful monthly rate under applicable state law, of the
unpaid balance which amount shall accrue from the Due Date of the invoice.

      b. Billing Disputes. Notwithstanding the foregoing, Customer may
permissibly fail to pay amounts charged for Vyvx's Services which are reasonably
disputed by Customer (along with late fees attributable to such amounts),
provided Customer: (i) pays all undisputed charges on or before the Due Date;
(ii) presents a written statement of any billing discrepancies to Vyvx in
reasonable detail together with appropriate supporting documentation ("Notice of
Discrepancy") within one hundred eighty (180) days of the Due Date of the
invoice in question; and (iii) negotiates in good faith with Vyvx for the
purpose of resolving such dispute within sixty (60) calendar days of the date of
the Notice of Discrepancy. In the event such dispute is mutually resolved in
favor of Vyvx, Customer agrees to pay Vyvx the disputed amounts together with
any applicable late fees within five (5) business days of the date of
resolution. In the event such dispute is mutually resolved in favor of Customer,
Customer will receive a credit for the disputed charges and no late fees shall
apply to the disputed amount. In the event such dispute is not mutually resolved
between the parties, Vyvx shall have the right to seek any applicable remedy
permitted under this Agreement. Vyvx shall not be obligated to consider any
Customer Notice of Discrepancy which is received by Vyvx one hundred eighty
(180) days after the Due Date. This right to dispute applies only to Vyvx's
Services provided to Customer and not to any dispute Customer may have with
respect to third parties. To the extent requested by Customer and to the extent
Customer has reasonable grounds for such dispute, Vyvx will act on Customer's
behalf to dispute any charges for third party services relating to this
Agreement, provided that such dispute shall be subject to the third party's
rules regarding disputed amounts and not the provisions of this Agreement and
provided further, that Customer shall indemnify Vyvx against any costs, expenses
or charges incurred by Vyvx as a result of its acting on behalf of Customer to
dispute charges for third party services.

3. SUSPENSION OF SERVICES. In the event that Customer has failed to pay any
amount when due, Vyvx shall have the right to suspend Services in full or in
part. Vyvx shall only exercise this Suspension Right by first providing Customer
with five business days' written notice by facsimile. If Vyvx receives payment
from Customer of all amounts due within the five-day notice period, then
Customer's Services shall not be suspended. Suspension of Services does not
affect Customer's obligation to pay the Service Charges through the term of the
applicable Service Schedule.

4. CUSTOMER'S CREDIT.

      a. Vyvx reserves the right to determine the creditworthiness of Customer
through available verification procedures or sources and Customer hereby
consents to Vyvx obtaining credit information regarding the Customer, its owners
and affiliates. If at any time, Customer presents, in Vyvx's reasonable
discretion, an undue risk of non-payment, or if Customer fails to comply with
the payment terms of this Agreement or any Service Order, Vyvx may require a
deposit or other forms of security for payment ("Deposit"). At Vyvx's sole
discretion, the Deposit shall be applied as payment to Customer's account either
(i) during the Term after Customer's payment history has been established or
(ii) as payment for the last month of the Term.

      b. If at any time there is a material adverse change in Customer's
creditworthiness or a material adverse change in Customer's financial position,
then in addition to any other remedies available to Vyvx, Vyvx may elect, in its
sole discretion, to demand reasonable assurance of payment from Customer,
including among others the posting of a deposit.

      c. A material adverse change in Customer's creditworthiness shall include,
but not be limited to: (i) Customer's default of its obligations to Vyvx under
this or any other agreement with Vyvx; (ii) failure of Customer to make full
payment of charges due hereunder on or before the Due Date on two (2) or more
occasions during any period of twelve (12) or fewer months; (iii) acquisition of
Customer (whether in whole or by majority or controlling interest) by an entity
which is insolvent or which is subject to bankruptcy or insolvency proceedings,
or which owes past due amounts to Vyvx or any Vyvx affiliate, or which is a
materially greater credit risk than Customer; or (iv) Customer's being subject
to or having filed for bankruptcy or insolvency proceedings or the legal
insolvency of Customer.

      d. A material adverse change in Customer's financial position shall
include, but not be limited to: (i) a decrease in net worth or working capital
of five percent (5%) or greater during any calendar quarter; or, (ii) a negative
net worth or working capital.

      e. If Customer has not provided Vyvx with (i) its financial statements
within ten (10) calendar days of Vyvx's reasonable request therefor or (ii) in
the event of a Vyvx demand for assurance of payment, assurance satisfactory to
Vyvx within ten (10) calendar days of Vyvx's notice of demand for such
assurance, then, in addition to any other remedies available to Vyvx, Vyvx shall
have the option, in its sole discretion, to exercise one or more of the
following remedies: (A) cause the start of any Service described in any
previously executed Service Order to be delayed pending receipt of such
financial statements or of the satisfactory assurance; (B) decline to accept a
Service Order or other requests from Customer to provide Service; or (C) suspend
all or any portion of the Service then being provided after giving Customer five
(5) calendar days prior written notice. If Customer provides satisfactory
assurance during the five (5) calendar day notice period, Vyvx will not suspend
any Service.

5. TERMINATION OF AGREEMENT OR SERVICE SCHEDULES.

      a. Termination For Cause. Except for an event of non-payment by Customer
hereunder which is addressed in subsection (b) below, either party may terminate
this Agreement if the other is in default of any material obligation contained
herein, which default has not been cured within thirty (30) calendar days
following the receipt of notice of such default setting forth the specifics of
such default. Termination and receipt of any applicable refund are Customer's
sole remedies in the event of any such default by Vyvx. Notwithstanding the
foregoing, the failure of any particular Service or Services to comply with the
Technical Specifications set forth individually for each Service in the attached
shall not be deemed a default by Vyvx, but may obligate Vyvx to provide Customer
with Outage Credits, if applicable under the relevant Service Schedule.
Termination of this Agreement for cause does not relieve Customer of any
obligations to pay Vyvx for charges accrued for Service which has been furnished
up to the time of termination nor does it relieve the Customer of all applicable
cancellation and/or disconnection charges. The remedies available to Vyvx as set
forth in this paragraph shall not be exclusive and Vyvx shall at all times be
entitled to all rights available to it under either law or equity.

      b. Termination For Non-payment. In the event Customer has failed to pay
any amount when due (except for amounts disputed by Customer in accordance with
this Agreement), Vyvx shall have the right to terminate this Agreement upon five
(5) business days' notice via facsimile to the Customer. Termination of this
Agreement pursuant to this subsection shall not relieve Customer of any
obligations to pay Vyvx for charges accrued for Service which has been furnished
up to the time of termination nor does it relieve the Customer of all applicable
cancellation and/or disconnection charges. The remedies available to Vyvx set
forth in this paragraph shall not be exclusive and Vyvx shall at all times be
entitled to all rights available to it under either law or equity.

      c. Termination for Violation of Law.

            (i) Additionally, Vyvx may, without incurring any liability, cancel
any Service prior to its commencement or disconnect such Service, in whole or in
part, immediately and without notice if Vyvx deems that such action is necessary
to prevent or to protect against fraud or to otherwise protect its personnel,
agents, facilities or Services under any of the following circumstances:

                  (A) if Customer unreasonably refuses to furnish or provides
false information to Vyvx regarding the Customer's identity, address,
creditworthiness, past or current use of Services, or its planned use of
Services; or

                  (B) if Customer is using the Services in violation of any
applicable law or regulation.

            (ii) In addition to its other termination rights hereunder, and with
respect to all Services, Vyvx may immediately disconnect any Service in whole or
in part if Vyvx determines that such Service violates any law, statute, or
ordinance, including the Communications Act of 1934 (as amended), or that the
imposition of any statute, or promulgation of any rule, regulation, or order of
the Federal Communications Commission or other governing body makes Vyvx's
performance under this Agreement commercially impracticable.

      d. Removal of Customer Equipment. Upon expiration or termination of a
Service Schedule, Customer shall remove all Customer-owned property and return
to Vyvx all software, access keys and other items that were provided to Customer
by Vyvx during the term of such Service Schedule in conjunction with the
Services.

6. TAXES. Customer acknowledges and understands that all charges are computed
exclusive of any applicable federal, state or local use, excise, gross receipts,
sales and privilege taxes, duties, fees or similar liabilities (other than
general income or property taxes), including without limitation, any tax or
charge levied to support the Universal Service Fund contemplated by the
Telecommunications Act of 1996, whether charged to or against Vyvx, its
suppliers or affiliates or Customer for the Services provided to Customer
("Taxes"). Vyvx maintains the right, for the duration of this Agreement, to
invoice and pass through to Customer at cost, any assessments, taxes, new or
increased fees, or other charges required to be collected from Vyvx, by any
governmental agency, department or entity. Such Taxes shall be paid by Customer
in addition to all other charges provided for herein. If Customer is exempt from
such Taxes, Customer shall provide to Vyvx a valid exemption certificate.

contractor(s) per this Agreement, then Customer shall require such contractor(s)
to comply with these insurance requirements and supply certificates of insurance

</TABLE>

      Firewall and Load Balancing pricing is available upon request, after
      customer assessment and requirements are gathered.

                        *Up to maximum 2 - 20 Amp additional increments (total
                        of 60 Amps). Additional power needs will be priced on an
                        individual case basis.

                        These prices are based on the physical design
                        specifications provided by iBeam to Williams
                        Communications on 6/12/01. Any changes beyond this
                        design may necessitate additional MRC and/or NRC
                        charges.

            (b)   Customer will reimburse Vyvx for all reasonable air and local
                  transportation, lodging, meals and any other out-of-pocket
                  expenses incurred in connection with any services

Schedule E                                                                Page 2
<PAGE>

                  Vyvx performs other than those outlined in the Agreement. Vyvx
                  will endeavor to gain approval from Customer before such
                  charges are incurred.

      4.2   Escort Fee. To the extent that the Customer, or a Customer-selected
            vendor, requires access to Customer Equipment for the purpose of
            repair, maintenance or replacement, a fee of $125 per hour, with a 1
            hour minimum, will be charged to Customer for providing access to
            such third party vendor into the Facilities ("Escort Fee"). The
            Escort Fee will not be charged to Customer for access to Customer
            Equipment that is required in connection with the installation or
            initial set-up (implementation period) of the Customer Equipment as
            outlined in Section 3.3 b i.

      4.3   Labor. If Williams performs labor for Customer, at Customer's
            request, other than in connection with the Services, then Customer
            agrees to pay Williams for that labor at the rate of $175 per hour.
            An example of when a labor charge would be charged is if Williams
            agreed to switch out an item of Customer's Equipment with a
            replacement part provided by Customer.

      4.4   Compliance with Media Center Policies. Customer agrees that it shall
            comply with all safety, security and similar policies and procedures
            of the Media Center that are provided to Customer in writing.

      4.5   Customer's Equipment.

            (a)   For the Services described above, Customer shall provide the
                  equipment attached as Appendix 2 to this Schedule E
                  ("Customer's Equipment") to the Media Center to be used in
                  connection with Vyvx provision of the Services to Customer.
                  Customer shall be responsible for the installation of hardware
                  and software on Customer's Equipment. To the extent that Vyvx,
                  or its designated third party vendors, provides technical
                  resources to implement routine maintenance or system repairs,
                  Customer will provide Vyvx all necessary training and
                  documentation relating to Customer's Equipment in order for
                  Vyvx personnel to carry out such maintenance activities. All
                  maintenance requests must be directed by the Customer and
                  furnished in writing to Vyvx.

            (b)   Customer's Equipment shall remain the property of Customer.
                  Maintenance, repair, or replacement of Customer's Equipment
                  shall be the sole responsibility of Customer. Customer may use
                  contractors for the purpose of such maintenance, repair or
                  replacement of Customer Equipment provided, however, that
                  Customer obtains Vyvx's prior written approval of any such
                  contractors (which approval shall not be unreasonably
                  withheld) and they are included on Customer's list of
                  authorized persons having access to the Media Center, as set
                  forth below. Upon expiration or termination of this Agreement,
                  Customer agrees to promptly remove Customer's Equipment.
                  Customer's failure to do so, or failure to provide Vyvx with
                  instructions regarding the disposition of Customer's Equipment
                  within forty-five (45) days of the expiration or termination
                  of the Agreement shall be deemed to be an abandonment of
                  Customer's Equipment, and Vyvx shall dispose of Customer's
                  Equipment in its sole discretion.

            (c)   The Media Center is staffed on a 24 x 7 basis. For security of
                  the Media Center and in the best interests of Vyvx and its
                  customers, access to the Media Center is restricted. Customer
                  shall have access to Customer's Equipment for normal
                  maintenance purposes from 08:00 to 17:00 local time, weekends
                  and holidays excluded, and Customer shall attempt to give the
                  Media Center a minimum of 24 hours advance notice. Customer
                  shall have access to Customer's Equipment for emergency
                  servicing purposes at any time, and Customer shall give a
                  minimum of one hour advance notice. Customer shall provide the
                  Media Center with a written list of all of Customer's
                  employees (or approved contractors) who are authorized to have
                  access to Customer's Equipment, and Customer shall update this
                  list as needed. The Media Center may deny access to any person
                  whose name is not on Customer's list of authorized persons.

Schedule E                                                                Page 3

            (d)   Any additional rack space required or requested by Customer
                  shall be subject to availability and to additional charge.

5.    OPERATIONAL NOTICES. If Customer has any technical problems with
      Customer's Equipment or the Services, Customer may call the Media Center
      at 1 (800) MXN-VYVX on a 24 x 7 basis. Vyvx will communicate with Customer
      as promptly as possible regarding any technical problems with Customer's
      Equipment or the Services. For purposes of these communications from Vyvx,
      Customer agrees that Vyvx should contact the operational contacts of

                        Facility Service Level Agreement

Section 1. Outage Credits

Facility Service Availability. Facility Service Availability is a measurement of
the percent of total time that Facility Service is operative when measured over
a thirty (30) consecutive day (720 hour) period. Facility Service is considered
inoperative when there has been a loss of AC power to the customer's rack(s).
For Facility Services on Williams' Network, availability shall be 99.999%,
measured over a thirty (30) day period. Availability for Third Party Services
(if applicable) is established by the third party providing such service.

Outage Credits. Customer acknowledges the possibility of an unscheduled,
continuous and/or interrupted period of time during which Facility Service fails
to conform to the technical specifications set forth in Section 2 below (an
"Outage"). An Outage shall begin upon the earlier of Williams' actual knowledge
of the Outage, or Williams' receipt of notice from the Customer of the Outage.
In the event of an Outage, Customer shall be entitled to a credit ("Outage
Credit") upon Williams' receipt of Customer's written request for such Outage
Credit. The amount of the Outage Credit for Facility Service shall be an amount
equal to ten (10%) percent of the monthly recurring charge for rack charges and
additional power, as set forth Section 7.1 of Exhibit A, of the rack(s) affected
by such Outage.

Remedy. The Outage Credit as set forth in this Section 1 shall be the sole and
exclusive remedy of Customer in the event of an Outage and under no
circumstances shall an Outage be deemed a default under the Agreement.

Limitations. Customer shall not receive an Outage Credit if the Outage is: (i)
caused by Customer's failure to utilize both power feeds provided to each rack
by Williams; (ii) caused by Customer or others authorized by Customer to use the
Services under the MSA, or those parties' failure to follow Williams' procedures
as communicated to customer; (iii) due to the failure of facilities, equipment,
systems or connections that are not provided by Williams; (iv) the result of
scheduled maintenance per Williams' standard PNMP process where Customer has
been notified of scheduled maintenance in advance; or (vi) due to a Force
Majeure event as defined in Section 14 of the Standard Terms and Conditions
document.

Credit Payment. Outage Credits shall be credited on Customer's next monthly
invoice for the affected Service or, if the Agreement has expired or terminated,
paid to Customer promptly following the expiration or termination of the
Agreement.

Section 2. Technical Specifications For Facility Service

Power. Williams shall provide backup electrical power and shared use of an
emergency generator that is maintained to support the Premises. Such backup
power shall be equal to the power specified in Customer's Facility Service Order
for the Facility Services. Williams shall provide as standard service, redundant
dedicated 20 amp, 110/208 volt AC circuits, connected to separate
uninterruptible power systems. Customer must properly employ both circuits as
redundant feeds (rather than multiple feeds) to meet facility service
availability requirements. Customer is responsible for managing power demand
within each rack.

Premises Environmental and Alarm Standards. Williams shall provide: (a)
monitored smoke and fire alarms; (b) lighting; (c) ground bus and cable
interconnect; (d) grounding conductors between the grounding grid and Customer's
Equipment; (e) interconnect signal and power cabling between Williams and
Customer; (f) raised flooring for air distribution and cable entry into customer
rack(s) and (g) general and administrative services directly relating to the
provision of the above listed Facility Services. Williams shall maintain ambient
temperature between 60(Degree)F and 75(Degree)F with an objective of 20-65%
(non-condensing) humidity and shall monitor deviations from such temperature
range.

Use of Power. Maximum AC power provided to Customer as A&B power shall be rated
for the rating of a redundant feed. Customer shall be responsible for load
management within Customer rack(s) to avoid power demand in excess of rated
capacity of a redundant feed of 20 amps at 110/208 volts AC.

Customer's Equipment Specifications. Customer shall only install or use
Equipment designed to operate satisfactorily between 60(Degree)F and 75(Degree)F
with 20-65% (non-condensing) humidity. Customer shall notify Williams of any
significant planned Equipment additions or deletions prior to any installation
or removal by Customer (this includes any addition or removal of a shelf or rack
or any equipment on a shelf or rack). Customer shall ensure that its Equipment
and surrounding area does not pose safety hazards to personnel.

Miscellaneous Restrictions. Customer shall not be allowed to:

o     Store anything outside of the assigned rack space
o     Place or store printed material, packaging, cleaning supplies, or any
      other non-data processing equipment within the rack space.
