                               SERVICE AGREEMENT
--------------------------------------------------------------------------------

This SERVICE AGREEMENT ("Agreement") is hereby made and entered into, as of
this 1st day of November, 2000 (the Effective Date), by and between
IPVOICE.COM, INC. a Nevada Corporation, ("IPVoice"), having its principal place
of business at 7585 East Redfield Road, Suite 202, Scottsdale, AZ 85260 and
BLUESHIFT TELECOM, INC. ("Blueshift") having its principal place of business at
853 Sanders Road, Suite 180, Northbrook, IL 60062. IPVoice and Blueshift are
also referred to herein each as a "Party" and collectively as the "Parties."

In consideration of the mutual promises contained herein, the parties agree as
follows:

1.   SERVICES. Blueshift hereby orders, and IPVoice hereby agrees to provide,
the Services, as specifically described on schedule A, attached hereto and
incorporated by reference herein, as revised from time to time by IPVoice in
accordance with generally applicable changes in IPVoice's service offerings. The
Services will be provided at the rates, and in accordance with the terms and
conditions, set forth in this Agreement and on Schedule A. IPVoice reserves the
right to increase or decrease pricing, change or discontinue the distribution or
licensing of any and all Products at any time and to cancel any service order
for such discontinued products upon thirty (30) days written notice and without
liability of any kind. Any reference to "Service" herein means Flat Rate Product
Sets. IPVoice can act as agent on behalf of Blueshift in placing orders with
such carriers and other entities, as shall be reasonably necessary for IPVoice
if IPVoice chooses to provide an extended Services offering to Blueshift.

2.   TERM. This Agreement shall be effective as of the Effective Date, shall
continue in full force and effect for the term set forth on Schedule A, hereto,
unless earlier terminated, and shall be automatically renewed for one or more
of the renewal terms set forth Schedule A, unless a Party notifies the other
Party in writing of its intent not to renew at least ninety (90) days prior to
termination of the then current term of this Agreement (the "Term"). In the
event, however, that IPVoice is unable to maintain such agreements and
facilities as shall be necessary to provide the Services at rates and on terms
and conditions reasonable acceptable to Blueshift, or IPVoice's performance
under this Agreement is held by the Federal Communications Commission (FCC),
one or more state regulatory commissions (State Commissions), or a court of
competent jurisdiction to violate any FCC or State Commission order,
regulation, rule or policy, IPVoice may terminate this Agreement.

3.   ADDITIONAL RESPONSIBILITIES OF IPVOICE. IPVoice shall establish, and from
time to time may amend, reasonable service order processing forms and
procedures, shall accept and process orders for the Services submitted by
Blueshift on such forms and in conformance with such procedures, and shall not
unreasonably discriminate against orders for the Services submitted by
Blueshift. No order for the Services shall be binding upon IPVoice unless and
until such order has been approved and accepted by IPVoice. IPVoice shall
exercise reasonable, good faith efforts (i) to provide at the request of
Blueshift the Services to Blueshift's retail customers ("Subscribers") on a
timely basis; (ii) to secure, operate and maintain, or caused to be operated
and maintained, such services and facilities as shall be necessary to provide
the Services; and (iii) to maintain all necessary and appropriate relationships
with network and other service providers. IPVoice shall provide the Services in
accordance with generally accepted industry standards. IPVoice shall provide
Blueshift with such support as shall be reasonable and appropriate.

4.   ADDITIONAL RESPONSIBILITIES OF BLUESHIFT. Blueshift shall use its best
efforts to market the Services. In so doing, Blueshift shall act in a lawful,
ethical and honest manner at all times, and shall resell the Services in
accordance with all applicable laws, statutes and ordinances, orders of courts
of competent jurisdiction, and rules, regulations, policies and orders of the
FCC and State Commissions, as well as other regulatory and governmental
authorities. Without limiting the generality of the above, Blueshift shall (i)
secure and maintain such regulatory authorizations as shall be necessary and
appropriate for the provision of the Services to Subscribers, (ii) not use the

immediately following three months. From time to time, at IPVoice's written
request, Blueshift shall promptly meet with IPVoice to discuss, and shall
provide IPVoice such information as IPVoice shall reasonably request regarding
activities undertaken by Blueshift pursuant to this Agreement.

End users who subscribe to services provided by Blueshift using the Services
(Subscribers) shall be Subscribers of Blueshift and not of IPVoice, and
Blueshift shall be solely responsible for billing, taxing and providing
Subscribers. Without limiting the generality of the above, Blueshift shall be
responsible for contracting with, ordering, modifying and terminating services
for, billing, collecting from, and performing Blueshift service functions for
(including, without limitation, responding to Subscribers' inquiries and
complaints, reporting service outages and other troubles) Subscribers. Except

Blueshift's signing, IPVoice will give Blueshift access to its account interface
with its MultiCom(TM) software, which can support order entry, agent management

agreed upon facilities. During the Term and for one (1) year thereafter,

to IPVoice, the usage-sensitive, recurring and non-recurring rates and charges
set forth on Schedule A, hereto, for the Services. If Blueshift discovers

not to exceed one percent (1%) per month of the past due balance may be applied
by IPVoice to any amount, including a disputed amount provided the dispute is
settled in favor of IPVoice, not paid by Blueshift on or before the Due Date.
Blueshift shall make all payments to IPVoice by wire transfer to such account at
such financial institution as designated by Schedule A or as IPVoice shall from
time to time designate. In the event that Blueshift in good faith disputes a
charge, it shall submit with timely payment of the undisputed amounts due, a
written notice containing the disputed charge and describing disputed charge.
IPVoice shall respond to said notice within 10 days of its receipt of the notice
and thereafter IPVoice and Blueshift shall attempt in good faith to resolve the
dispute. Disputes shall not be cause for Customers to delay payment of the
undisputed balance to IPVoice according to the terms outlined.

During the periods set forth in this section the amount being disputed will not
be considered Past Due. In the event that the Parties are unable to resolve the
dispute, either Party may submit the matter to arbitration pursuant to Section
14, hereof, in which event, the dispute shall be resolved through binding
arbitration. Blueshift shall pay all disputed amounts in accordance with this
Section 6 subject to resolution of the dispute. All invoices not disputed by
Blueshift within ten (10) days of Blueshift's receipt thereof shall be final and
binding upon Blueshift.

7.   TERMINATION/DEFAULT. This Agreement may be terminated without liability to
the terminating Party: (i) at any time by mutual agreement of the Parties; (ii)

Agreement shall relieve a Party of liabilities previously accrued hereunder.

penalties for delay in delivery when such delay is due to the elements, acts of
God, delays in transportation, strikes, fire, or any other causes beyond the

subsequent to its disclosure by the Proprietary Party to the Receiving Party, is

this Agreement or disclosed to any third party without the Proprietary Party's
prior written consent. The Receiving Party shall use at least the same degree of
care and discretion it uses with regard to its own proprietary or confidential

Proprietary Information, including, but not limited to taking steps to: (i)
advise all Receiving Party employees with access to the Proprietary Information
