                GLOBIX STANDARD SERVICE LEVEL AGREEMENT (vA2.01)

 NOTICE TO ALL CLIENTS: TO QUALIFY FOR THE BELOW SET FORTH ENTITLEMENTS CLIENT

1.  NETWORK AVAILABILITY AND UPTIME.  Globix guarantees one hundred (100%)
percent Backbone Network Uptime with at least ninety-nine (99%) percent
sustained Packet Throughput (PT). To determine compliance, measurements are
taken on a continual basis on the Globix U.S. Domestic Backbone Network between
various combinations of any two of our Points of Presence (POPs).

A.  Network availability refers to the ability of a Client to access the Globix
Backbone Network.

B.  Globix measures latency on the Globix Backbone Network. These measurements
are taken as round trip times between core routers within the Globix POP
facilities in the continental United States. Globix guarantees an average round
trip latency of not more than one hundred and twenty (120ms) milliseconds. If
this standard is not met, Globix will credit the Client as detailed in Section
6.

C.  Network Unavailability is defined as a packet loss in excess of fifty (50%)
percent for fifteen (15) consecutive minutes or more or one that exceeds one
(1%) percent for two (2) or more consecutive hours on the Globix Backbone
Network. Periodically, Globix will upgrade or find the need to repair or replace
vital network equipment which interruptions are foreseeable events common to all
First Tier network providers. Neither these maintenance events, necessary for
providing a consistently high level of service, nor client caused outages or
disruptions beyond Globix's control are considered "Network Unavailability" as
covered by this SLA.

D.  Clients must report Network Unavailability of longer than fifteen (15)
consecutive minutes or the aforementioned packet loss to Globix Client Support
Center within forty-eight (48) hours of the event. If the event reported by the
Client is confirmed by Globix Customer Service, the Client will receive a
pro-rated service credit as detailed in Section 6. However, the total of any
credits granted for any twenty-four (24) hour period may not exceed one (1) full
day's pro-rated fee.

E.  Network Unavailability for Point to Point Leased Line Dedicated Access
Clients caused by a failure due to the Local Exchange Center (LEC) is covered by
this SLA for any service with a Globix ordered local loop circuit. Globix will
use industry standard efforts to remedy any circuit failures when working with
the LEC. The pro-rata discount for this type of outage is limited to Internet
Port access fees only and will be applied to Client's invoice as described in
Section 6.

F.  Network Unavailability for Frame Relay and Digital Subscriber Link Service
caused by a failure due the to LEC Frame Relay Network or LEC (all circuits, is
not covered by this SLA and Globix will not be liable for same.

2.  HARDWARE AND SOFTWARE MONITORING AND UPTIME.  Equipment not owned and
operated by Globix is not directly monitored. However, indirect monitoring is
provided in the form of a standard Ping Test performed every three hundred (300)
seconds to one (1) IP address per Client service account. In the event that two
(2) consecutive Ping Tests fail, Globix will notify Client in accordance with
the standard notification policy detailed in Section 3. However, Globix will not
take any corrective action unless a Maintenance Agreement between the parties is
in effect.

3.  NOTIFICATION OF OUTAGES AND SERVICE INTERRUPTION EVENTS.  Fifteen (15)
minutes after an outage is officially recorded, which occurs when the second
Ping Test fails, Globix will contact Client's designated representative by
e-mail, phone, or pager. Clients reporting service interruption events or
outages of any kind may use the "Single Point of Contact" local support
telephone number for access to the twenty-four (24) hour Support Group.

4.  ACCESS TO STATISTICS.  Client will have access to a public web page
detailing Globix Backbone Network availability and latency statistics. Clients
may enter separate agreements for additional statistics accessible through
private web pages with Client specific usage statistics as detailed in that
agreement.

5.  INSTALLATION INTERVAL GUARANTEE.  If Globix is unable to meet the standard
installation interval for any Service, and Client has been billed for the full
installation fee (i.e., not discounted), Globix will credit Client's account
with fifty (50%) percent thereof excluding any local loop installation charges.
Since Client may choose to purchase one of several levels of expedited
Installation Service, if Globix fails to meet the purchased installation
deadline, Globix will discount the expedite fee to the cost associated with
whichever interval it meets. For example, if Client orders a "Rush" installation
package and Globix meets the "Standard" interval, Globix will refund the
difference between the "Rush" and "Standard" install fee. In order to qualify
for this installation guarantee, Client's account must be in good standing. All
these entitlements are subject to Globix's performance not being precluded by
Client created or force majeure events.

6.  WARRANTIES AND DISCLAIMERS BY GLOBIX.  Service Level Warranty. In the event
Client experiences any of the following and Globix determines in its reasonable
judgment that such inability was caused by Globix's failure to provide Internet
Data Center Services for reasons within Globix's reasonable control and not as a
result of any action or inaction of Client or any third parties (including
Client equipment and/or third party equipment), Globix will, upon Client's
request in accordance with Section 6C., credit Client's account as described
below:

A.  Inability to Access the Internet (Downtime). If Client is unable to transmit
and receive information from Globix's Internet Data Centers (i.e., Globix's LAN
and WAN) to other portions of the Internet because Globix failed to provide
Internet Data Center Services for more than fifteen (15) consecutive minutes,
Globix will credit Client's account the pro-rata Globix connectivity charges
(i.e., all bandwidth related charges) for one (1) day of Service, up to an
aggregate maximum credit of connectivity charges for seven (7) days of Service
in any one calendar (1) month. Globix's scheduled maintenance of the Internet
Data Centers and Internet Data Center Services, as described in the Policies and
Procedures, shall not be deemed to be a failure of Globix to provide Internet
Data Center Services. Pro-rata daily credits are limited to one full day's
credit per twenty-four (24) hour Service period.

B.  Packet Loss and Latency. While Globix does not proactively monitor the
packet loss or transmission latency of specific Clients, Globix does monitor the
packet loss and transmission latency within its LAN and WAN. If Globix discovers
(either from its own efforts or after being notified by Client) that Client is
experiencing packet loss in excess of the level set by the SLA purchased by
Client ("Excess Packet Loss") or transmission latency in excess of one hundred
and twenty (120ms) milliseconds round trip time (based on Globix's measurements)
between any two POPs within Globix's U.S. network (collectively, "Excess
Latency", and with Excess Packet Loss "Excess Packet Loss/Latency"), and Client
notifies Globix (or confirms that Globix has notified Client), Globix will take
all actions necessary to determine the source of the Excess Packet Loss/Latency.

(i)  Remedy of Excess Packet Loss/Latency. If the excess Packet Loss/Latency
     remedy is within the sole control of Globix, Globix will remedy the Excess
     Packet Loss/Latency within two (2) hours of determining the source of the
     Excess Packet Loss/Latency. If the Excess Packet Loss/Latency is caused
     from outside of the Globix LAN or WAN, Globix will notify Client and will
     use industry standard efforts to notify the party(ies) responsible for the
     source and cooperate with it/them to resolve the problem as soon as
     possible.

(ii) Failure to Determine Source and/or Resolve Problem. If Globix is unable to
     determine the source of and remedy the Excess Packet Loss/Latency within
     the time periods described above (where Globix was solely in control of the
     source), Globix will credit Client's account the pro-rata Globix
     connectivity charges for one (1) day of Service for every two (2) hours
     after the time periods described above that it takes Globix to resolve the
     problem, up to an aggregate maximum credit of connectivity charges for
     seven (7) days of Service in any one (1) month.

C.  NOTE: CLIENT MUST REQUEST CREDIT. To receive any applicable credits, Client
must notify Globix Customer Service within two (2) business days from the time
Client becomes eligible to receive a credit or forfeit its right to receive a
credit. Globix will contact Client to review the status of the credit request
and to determine the applicable credit, if any, due Client.

D.  Remedies Not Cumulative - Maximum Credit. In the event that Client is
entitled to multiple credits arising from the same event, whether under this SLA
or any other SLAs, such credits shall not be cumulative. Client shall be
entitled to receive only the maximum single credit available for such event. In
no event will Globix be required to credit Client in any one (1) calendar month
Globix connectivity charges in excess of seven (7) days of Service. A credit
shall be applied only to the month in which the incident took place. Client
shall not be eligible to receive any credits for periods during which Client
received any Service free of charge.

E.  Termination Option for Chronic Problems. If, in any single calendar month,
Client would be able to receive credits totaling fifteen (15) or more days (but
for the limitation in subparagraph D above) resulting from three (3) or more
events during such calendar month or, if any single event entitling Client to
credits under subparagraph A exists for a period of eight (8) consecutive hours,
then, Client may terminate the applicable Service for cause and without
termination fee by notifying Globix within five (5) days following the end of
such calendar month. Termination will be effective thirty (30) days after
receipt of such notice by Globix.

<PAGE>
     B. "Client previously was paying $6,000/mo for SCH fees based on threshold

     current business model has been significantly lower and in consideration of
     its renewal of its Service for a twenty-four (24) month term, Globix hereby
     waives any SCH fees providing Client's complaint level remains reasonably
     consistent with past experience. In the event (i) its complaint level
     exceeds 1,000/mo and Client's email volume to complaint ratio exceeds 1
     Mil:350 or (ii) if Client changes its business model and such complaints
     are still in accordance with the Globix Acceptable Use Program, Globix
     shall have the right to assert its then current SCH fee program.

     C. "Client shall have 48 hours from the time that notice of a violation of
     the "Policy on Spam" section of the Globix Acceptable Use Policy ("AUP") is
     sent, to respond to and cure such violation in order to prevent future
     violations, and when such violation(s) result in the number of complaints
     referenced in Section 6.3B(i) or (ii) above, Globix may invoke its rights
     under the AUP. This notice period shall not apply to any violation which,
     at the time of the incident, (i) is a violation of any law, rule or
     regulation, whether Federal, State, local or any other jurisdiction; (ii)
     if the 48 hour cure notice has a materially damaging impact on Globix's
     business, in the reasonable discretion of Globix; or (iii) is contrary to
     any order or direction of a governmental agency."

9.   In Section 7.1 at the end thereof add "Globix also represents and warrants
     that it will maintain (i) the level of physical security at its facility at
     least at current levels in all material respects; (ii) the air temperature
     inside Client's enclosure at or below 72 degrees F to be measured at the
     perforated floor tile level - failing to do so with resultant temperatures
     of 72-75 degrees F for an hour or more in a day will entitle Client to one
     (1) day service credit and temperature above 75 degrees F for an hour or
     more in a day will entitle Client to terminate the applicable Service
     without termination fees on sixty (60) days written notice and payment of
     accrued payment obligations provided said notice is given within thirty
     (30) days of the incident; (iii) sufficient airflow such that if airflow is
     less than 325 cubic feet per minute per one (1) unrestricted perforated
     floor tile for an hour or more in a day will entitle Client to terminate
     the applicable Service without termination fees on sixty (60) days written
     notice and payment of accrued payment obligations provided said notice is
     given within thirty (30) days of the incident; and (iv), when Client's cage
     complies with the "Hot Air/Cool Air" Aisle conventions set forth on the
     attached diagram entitled Digital Impact Future Cage Redesign, hereby
     incorporated by reference herein, Globix's obligation in (ii) above will be
