or provide any materials or information, directly or indirectly, nor assign or
utilize any individual assigned to perform services for or on behalf of TI USA
ISP hereunder, to perform services for or in support of any TI USA ISP

                                      -5-
<PAGE>   6

                  5.1.1. For purposes of this Agreement, the term "Competitor"
            shall mean any other firm, person or enterprise conducting a
            business or providing or supporting a product or service
            substantially similar to TI USA ISP in and to the Target Market or
            any task or work effort whose intent or result is or will be
            substantially similar to the Services provided hereunder in and to
            the Target Market (including, without limitation, any parent,
            subsidiary, joint venture, partnership, operating, franchise and
            affiliated companies and any merged or successor companies of
            these). If there is any doubt whether a person, firm or enterprise
            is a "Competitor" for purposes hereunder, IDT shall request
            TI USA ISP's advance written approval (not to be unreasonably
            withheld), and TI USA ISP's response to such request shall be deemed
            final and controlling for all purposes hereunder.

                  5.1.2. Nothing contained in this Agreement shall be deemed or
            construed to prohibit, and TI USA ISP hereby consents to,
            cross-selling by IDT of any of IDT's products and services not
            covered by this Agreement to TI USA ISP's customers in exchange for
            commissions to be paid by IDT to TI USA ISP's at rates to be agreed
            upon by the Parties.

            5.2. IDT and the IDT Entities acknowledge and agree that in the
event of a breach or threatened breach of any of the provisions of this
Section 5, TI USA ISP will have no adequate remedy in damages and, accordingly,
shall be entitled to seek injunctive relief; provided, however, no specification
of a particular legal or equitable remedy shall be construed as a waiver,
prohibition or limitation of any legal or equitable remedies in the event of a
breach hereof.

      6. Service Levels.

            6.1. Service Levels. IDT shall provide the Services in accordance
with the service level criteria set forth on Exhibit B hereto (the "Service
Levels").

            6.2. Adjustment of Service Levels. Two months after the Effective

the Service Levels for the preceding 6 months (for the preceding two (2) months
for the first revision after the Effective Date) and may mutually agree in
writing to adjust such Service Levels for the subsequent six month period to
reflect increases, decreases or changes to the Services. In addition, either
Party may, at any time upon notice to the other Party, initiate negotiations to
review and, adjust any Service Level which such Party in good faith believes is
inappropriate at the time; provided, however, that in the event that the Parties
fail to mutually agree upon any such adjustment(s) to the Service Levels, the
original Service Levels as agreed to by the Parties as of the Effective Date
shall control.

            6.3. Reports. IDT shall provide daily, weekly and monthly system
performance reports to TI USA ISP in such forms and at such times as are agreed
upon


                                      -6-
<PAGE>   7

by TI USA ISP and IDT as necessary, but at a minimum providing comparable
information as that contained in IDT's own similar system performance reports
and which are reasonably consistent with any industry standards for such
reports.

            6.4. Root Cause Analysis. Within one day of receipt of a notice from
TI USA ISP with respect to (i) IDT's material failure to provide any of the
Services in accordance with the Service Levels or (2) IDT's repeated failure to
provide any of the Services in accordance with the Service Levels, IDT shall (a)
perform a root-cause analysis to identify the cause of such failure, (b) correct
such failure, (c) provide TI USA ISP with a report detailing the cause of, and
procedure for correcting, such failure, and (d) take all reasonable steps to
prevent recurrence of such failure.

      7. Assignment of IDT Customers.

            7.1 In consideration of the benefits derived by IDT from the Joint

and other good and valuable consideration, and subject to the provisions of the
second sentence of Section 7.2 below, IDT hereby irrevocably assigns, transfers
and conveys to TI USA ISP all right, title and interest in and to the accounts,
agreements, registration and other information, lists and all customer data of
the IDT Customers and the right to service such IDT Customers so that TI USA ISP
shall have exclusive, unlimited ownership rights therein including, without
limitation, all End User Information relating thereto. As part of the Services,
IDT shall, at its sole cost and expense, arrange for the delivery, transfer and
integration of such IDT Customer accounts and all related End User Information
into a segregated customer database together with the other End User Information
maintained by IDT on behalf of TI USA ISP. The Parties will agree on joint
promotions to cross-sell IDT products and Services to TI's customers for a
commission to be agreed upon by the Parties.

non-transferable license to use and access such necessary account information of
IDT Customers, any End User account with TI USA ISP and any End User Information
relating thereto, for the sole purpose of providing the Services to End Users as
specifically permitted hereunder and solely during the Term of this Agreement.
Except for purposes of cross selling activities permitted by Section 5.1.2 and
Section 7.1. IDT may not otherwise use, copy, reproduce, transmit, disclose or
exploit the End User Information or any component thereof for any reason, nor
sublicense, distribute, group, compile, aggregate or transfer the End User
Information for its own benefit or for the benefit of any third party, without
the prior written consent of TI USA ISP. IDT agrees to comply with all legal and
regulatory requirements in connection with the storage and use of the End User
Information and to comply with such other legal and regulatory requirements of
which it is notified in writing by TI USA ISP from time to time.

ISP to IDT in writing during the Term (TI USA ISP's name and such marks and
logos being referred to herein as the "Marks"), solely in connection with the
provision of Services by IDT to prospective and existing End Users in the Target
Market as described herein. Use of the Marks shall be subject to any reasonable
general usage guidelines and notice requirements provided by TI USA ISP from
time to time, including, without limitation, TI USA ISP's right, in its sole
discretion, to change the appearance and/or style of its Marks or add or remove
any Mark from the scope of the license granted hereunder. All use of the Marks
by IDT as permitted hereunder together with any goodwill resulting from such use
shall inure to the benefit of TI USA ISP and except for the limited right and
license granted above, IDT shall not have or obtain any right, title or interest
in or to the Marks. IDT agrees not to adopt, use or apply for registration of
the Marks (or any mark confusingly similar thereto) anywhere in the world, nor
shall IDT engage, participate or otherwise become involved in any activity or
course of action that diminishes and/or tarnishes the image and/or reputation of
the Marks. Each initial use of the Marks by IDT shall at all times be subject to
the review and prior written approval of TI USA ISP which will, so long as each
such use is consistent with this Agreement, not be unreasonably withheld, but
which is revocable at any time upon written notice to IDT. IDT will cooperate
with TI USA ISP and execute any documents (e.g., registered user agreements
filed with governmental agencies) which may be required or desirable in any
jurisdiction to protect TI USA ISP's rights in the Marks.

      9. Pricing and Payment.

<PAGE>   9

            9.2 Except as specifically set forth in this Agreement, each Party
remains responsible for establishing its own prices and charges to End Users,
customers, subscribers or otherwise in connection with its own offerings,
products and/or services available in the commercial marketplace. Furthermore,
except as otherwise provided herein or subsequently mutually agreed upon in
writing, each Party bears its own expenses and costs associated with performing
its obligations under this Agreement.

      10. Right to Audit.

            10.1 During the Term and for a period of 180 days thereafter, upon
at least five (5) business days notice to IDT, IDT shall provide TI USA ISP or
its external auditors with access to IDT's facilities during normal business
hours for the purpose of conducting an audit of IDT's operations as it deems
necessary to insure that (i) IDT has established reasonable and adequate
procedures for providing the Services, (ii) the accuracy of pricing under
Section 9.2 above, and (iii) protection of any TSI USA ISP Proprietary
Information obtained as a result of this Agreement, including, without
limitation, End User Information. IDT shall provide TI USA ISP with all
reasonable assistance as is necessary for the conduct of such audit by
TI USA ISP. In the event that TI USA ISP determines that IDT has not established
reasonable and adequate procedures for compliance with IDT's obligations
hereunder, IDT agrees to take such appropriate corrective action as the Parties
may mutually agree. IDT agrees, upon the request of TI USA ISP, to allow
representatives of TI USA ISP to meet with IDT's management in order to discuss
IDT's general procedures in providing the Services and protecting the security
of TI USA ISP Proprietary Information resident on IDT's systems or in the
possession of IDT. No such meetings, recommendations or other cooperation
between the Parties regarding security and confidentiality shall be construed or
deemed to relieve IDT of its obligations hereunder.

            10.2 During the Term and for a period of eighteen (18) months
thereafter, upon at least five (5) business days notice to IDT, IDT shall
provide TI USA ISP or its external auditors with access to IDT's books and
financial records and any other supporting documentation relating to the Access
Fees due to TI USA ISP hereunder. Any such audit will be conducted during IDT's
normal business hours and at the IDT location where the relevant records are
kept in the normal course of business and shall be conducted to minimize any
disruption to IDT's business activities. In the event that any such audit
reveals that IDT has underpaid any amounts due to TI USA ISP under this
Agreement by more than five percent (5%) IDT will immediately pay the difference
(required payment minus actual payment) and interest thereon at LIBOR + 2% from
the date due until the date paid to TI USA ISP together with the reasonable
costs of such audit. If the audit reveals that IDT has overpaid any amounts due
to TI USA ISP under this Agreement by more than five percent (5%), then TI USA
ISP shall reimburse IDT the difference between the amount due and the amount
paid.

            10.3 During the Term and for a period of at least three (3) years
thereafter, IDT shall retain complete and accurate books, records and supporting


                                      -9-

documentation sufficient to document the Services provided to and Access Fees
paid by End Users and to satisfy its obligations under Sections 10.1 and 10.2
above.

11. Term and Termination.

      11.1 This Agreement shall commence as of the Effective Date and shall
continue in full force and effect for an initial term of eighteen (18) months
("Term") unless terminated earlier in accordance with the termination provisions
hereunder. Upon at least thirty (30) days' notice prior to the expiration of the
Term TI USA ISP may elect to renew this Agreement for an additional one (1) year
term on the same terms and conditions, subject to making mutually agreed upon
adjustments to pricing and other terms necessary to reflect changes in market
conditions. Thereafter, TI USA ISP may elect to renew this Agreement on terms to
be mutually agreed upon by the Parties. Termination of this Agreement at any
time shall not affect any rights, obligations or interests arising prior to the
effective date of termination and which, to give effect to their meaning, must
continue in accordance with their terms.

      11.2 If there is any material breach of this Agreement by one Party, the
other Party may (reserving cumulatively all other remedies and rights under this
Agreement and in law and in equity) terminate this Agreement, in whole or in
part, by giving thirty (30) days' written notice; provided, however, that such
termination shall not be effective if the breach has been cured prior to the
expiration of said thirty (30) days.

                  11.2.1 Notwithstanding the foregoing, IDT's material or
            repeated failure to comply with the Service Levels set forth in this
            Agreement in the manner described in Section 6.4 shall constitute a
            material breach of this Agreement whereupon TI USA ISP may
            (reserving cumulatively all other remedies and rights under this
            Agreement and in law and in equity) terminate this Agreement, in
            whole or in part, by giving IDT three (3) business days' written
            notice; provided, however, that such termination shall not be
            effective if the breach has been cured prior to the expiration of
            said three (3) business days; provided, further, however, that the
            failure to comply with a particular Service Level in three (3)
            consecutive months or in five (5) months in any twelve (12) month

Proprietary Information to its employees, auditors, regulators, attorneys and
financial advisors on a "need to know" basis only. The term "Proprietary
Information" shall mean all information which one Party, directly or indirectly,
obtains from the other Party as a result of this Agreement, excluding
information falling into any of the following categories:

                  (a) Information that already is in the public domain through

safeguards and precautions which such Party observes with respect to its own
confidential, sensitive and proprietary information. It shall not be deemed to
be a breach of the obligation to maintain Proprietary Information in confidence
if Proprietary Information is disclosed upon the order of a court or other
governmental entity provided, however, that the Party served with such order

limited to SLIP/PPP accounts, UNIX Shell accounts and ISDN Connection accounts.

<PAGE>   37

      2. IDT dial-up accounts are provided for use in conformance with these
Guidelines, Terms and Conditions. IDT reserves the right to investigate
suspected violations of the Guidelines. When IDT becomes aware of possible
violations, IDT may initiate investigations that may include gathering
information from the Accountholder or Accountholders involved and the
complaining party, if any, and examination of material on IDT's servers.

      3. During an investigation, IDT may suspend the account or accounts
involved and/or remove the material involved from its servers. If IDT believes a
violation of these Guidelines has occurred, it may take responsive action at its
sole discretion. Such action may include, but is not limited to, temporary or
permanent removal of material from DT's servers, the cancellation of news group
posts, warnings to the Accountholder or Accountholders responsible, and the
suspension or termination of the account or accounts responsible. IDT reserves
the right to terminate an Accountholder's account with or without notice. IDT,
at its sole discretion, will determine what action will be taken in response to
a violation on a case-by-case basis. Violations of these Guidelines could also
subject the Accountholder to criminal or civil liability.

      4. To comply with applicable statutes and lawful government requests, IDT
reserves the right to access and disclose any information. This may include
disclosing the usernames of accountholders and other pertinent information. IDT
will fully cooperate with law enforcement authorities in investigating suspected
lawbreakers and reserves the right to report to law enforcement any suspected
illegal activity that it becomes aware of.

      B. USE OF MATERIALS

      1. Materials in the public domain (e.g. images, text and programs) may be
downloaded or uploaded using IDT services, Accountholders may also re-distribute
materials in the public domain. The Accountholder assumes all risks regarding
the determination of whether material is in the public domain.

      2. The Accountholder is prohibited from storing, distributing or
transmitting any unlawful material through IDT services. Examples of unlawful
material include but are not limited to direct threats of physical harm, child
pornography, and copyrighted, trademarked and other proprietary material used
without proper authorization. The Accountholder is also prohibited from storing,
distributing or transmitting any information that may be determined to be of a
harassing nature. Further, the Accountholder may not post, upload or otherwise
distribute copyrighted material on IDT's servers without the consent of the copy
right holder. The storage, distribution, or transmission of unlawful materials
could subject the Accountholder to criminal as well as civil liability, in
addition to the actions outlined in Section I.IA. above.

      3. The Accountholder may not store or distribute certain other types of
material on IDT's servers. Examples of prohibited material include, but are not
limited to, programs containing viruses or Trojans and tools to compromise the
security of other sites.

<PAGE>   38

      C. PASSWORDS

      1. IDT Corp. personal dial-up accounts are for individual use only.
Accountholders may not share passwords or accounts with other individuals.
Accountholders are also responsible for maintaining the security of their
accounts and passwords.

      2. IDT shall provide passwords to Accountholders. In the event that the
security of an Accountholder is compromised, IDT shall provide the Accountholder
with a new password.

      3. IDT staff may monitor the security of Accountholders' passwords at any
time. An Accountholder with an insecure password may be directed to change the
password to one which complies with the above rules. Accountholders who
repeatedly choose insecure passwords may be assigned a password by IDT;
continued failure to maintain password security shall be immediate grounds for
account termination

      D. System Security

      1. The Accountholder is prohibited from utilizing IDT services to
compromise the security or tamper with IDT's system of resources or accounts on
any of IDT's computers, routers, terminal servers, modems, or any other
equipment at IDT or at any other site. Use or distribution of tools designed for
compromising security is prohibited. Examples of the tools include but are not
limited to password guessing programs, cracking tools or network probing tools.
Any attempt to access any of IDT's corporate assets is strictly prohibited.

      2. IDT reserves the right to release the user names of Accountholders
involved in violation of system security to system administrators at other
sites, in order to assist them in resolving security incidents.

      E. System Resources

      1. IDT will allocate system resources to provide all Accountholders with
the best service possible. As part of resource allocation, IDT may limit,
restrict or prioritize access to system resources, including CPU time, memory,
disk space, session length, and the number of sessions.

      2. Additionally, IDT may institute services and fees for Accountholders
who are interested in accessing system resources above and beyond acceptable
usage.

      3. IDT may log instances of abuse of system resources, including but not
limited to those outlined below, and take action as outlined in Section II.A.
above.

      4. System abuse is defined as any use of IDT resources which disrupts the
normal use
<PAGE>   39

of system or Internet services for others. Examples of system abuse include, but
are not limited to attempting to disrupt the sessions of other Internet users,
consuming excessive amounts of time, memory or disk space bandwidth or otherwise
affecting the performance of IDT servers or networks.

      5. Accountholders may not run programs which provide network services from
their accounts. Example of prohibited programs include, but are not limited to,
Mail, HTTP, IRC servers and multi-user interactive forums.

      6. Accountholders may only make use of IDT system resources while logged
in. Further, Accountholders are not permitted the use of software of any device
that would allow the account to stay logged on while the Accountholder is not
actively using the system or the account. The sole exception to this policy are
e-mail filters that process and sort mail as it arrives.

      III. ACCEPTABLE USAGE

      Acceptable usage is hereby defined as the normal activities associated
with the usage of the Internet, including but not limited to usage of IDT's
systems and network facilities for accessing the WWW, IRC, Usenet News, E-Mail,
and other Internet features. Depending on the account type, this may include a
moderate amount of file storage on IDT's servers for Accountholders' own
personal web page, file access area (FTP), and possibly Unix utilities used in a
shell account. Shell users may be permitted to use their own software, subject
to IDT's discretion, provided such software does not use excessive system
resources or in any way compromise system integrity and does not fall under any
of the prohibited activities listed within this document. This policy is subject
to any and all laws and regulations set forth by the Federal, State or any other
governmental authority.

      IV. PROHIBITED ACTIVITIES

      Activities specifically prohibited by IDT administration include but are
not limited to the following:

      1. Background and/or server-type applications including but limited to IRC
Bots, HTTP Servers, and any other process that is initiated by the user that
upon execution continues the user's account even after log-out.

      2. Long-term storage of data. Long-term storage of data is referred to as
the storage of files which are not used regularly in an account for an extended
period of time. This specifically includes but is not limited to programs such
as shareware programs which the user may download to their account for purposes
of transferring to their home computer. Such programs should be removed at such
time as they are successfully transferred to the user's personal system.
<PAGE>   40

      3. Flooding or abuse of other users. Flooding is a fairly common
occurrence on the Internet, and one that is strictly prohibited by IDT. Flooding
takes place in numerous ways, including but not limited to ICMP flooding, mail
bombing (sending large amounts of e-mail repeatedly to a person for purposes of
harassment), mass mailings to multiple addressees, msg/CTCP flooding on IRC, as
well as other, less common methods.

      a. 'Mail-bombing' constitutes sending more than ten (10) similar messages
to the same e-mail address and 'news-bombing' is defined as sending more than
10MB of data to one particular newsgroup.

      4. Attempts to compromise system and/or network security Programs such as
'packet sniffers', password crack programs and similar utilities found to be
running from a user s account are prohibited. This forbidden activity also
includes any attempts to penetrate either the IDT system or the accounts of
others, regardless of whether or not the intrusion results in corruption or loss
of data.

      5. Sharing of accounts Sharing of a user's account with another party for
purposes of avoiding payment for a second account is strictly prohibited.

      6. Attempts to bypass resource usage limitations. In order to provide fair
service to all IDT users, IDT has implemented certain resource limitations, the
two most common being disk quotas on the servers and idle time-outs on dial-ups.
Attempts to bypass disk usage quotas by any means may result in immediate loss
of system privileges. Attempts to bypass the idle time-outs are also prohibited.
The current idle time-out limit is twenty minutes.

      7. PPP/SLIP Emulation Software. Since PPP/SLIP is a product offered by
IDT, users desiring such access are required to sign up for that service, rather
than attempting to emulate it by software. Any such software will be removed
from the user's account by IDT immediately when found. All software provided by
IDT to Accountholders are copyrighted by IDT and may not be tampered with,
decompiled or reverse engineered.

      8. Conducting business through a personal account The regular dial-up
accounts (Basic and Premium) provided by IDT are designed for the home/casual
user and not to provide the level of service required for conducting business.
Therefore, conducting business with an individual account is prohibited. If a
business account is desired, please contact the IDT Dedicated Sales Department

      9. Excessive use of system resources. IDT account descriptions specify
limits on bandwidth and disk space utilization. Any use in excess of those
stated limits is not permitted, unless IDT has made special arrangements with
the user. This segment can be broken down into two parts - system and dial-up.

      a. System Limits - This can be defined as the continued use of Programs or
commands that take a large amount of system resources, be that processor time,
network,

<PAGE>   41

bandwidth, and/or drive space on the host system.

      b. Dial-Up - This prohibition focuses on the continued use of a dial-up
port to simulate a dedicated connection for the user's home system. Dial-up
accounts are designed solely to provide on-demand access for Accountholders, not
dedicated connections. If a dedicated connection is desired, the Accountholder
needs to speak with IDT's Dedicated Sales Department (800)225-5438 Ext. 4.

      10. E-Mail abuse. E-mail abuse is typically manifest in three forms:

      a. The sending of a message to unsolicited individuals or individuals who
have expressed a desire not to receive like messages;

      b. The sending of harassing and/or threatening messages to other users;

      c. The forging of e-mail addresses ('spoofing') in which the user
manipulates the email address so that the message appears as though it came from
another user. Any attempts to forge the headers will result in account
termination. Further, this prohibition extends to sending unsolicited mailings
from another service, which in any way implicates the use of IDT's service,
IDT's equipment or any of IDT's e-mail addresses.

      11. Usenet order news abuse. Similar to e-mail abuse, includes forging of
addresses, harassment/threats, the posing of the same message to multiple news
groups ('spamming'), as well as the posting of information in groups where it is
not relevant and unwanted.

      12. Pyramid/money-making schemes. Such activities as the transfer of
information or solicitation of persons via the Internet in an attempt to extort
money or other valuables or the use of pyramid/chain letters, are all
prohibited.

      13. Pirated software. Pirated software is defined as the illegal exchange
of software via the Internet for purposes of avoiding the purchase of said
software by the individuals involved. This includes most commercial applications
such as Adobe Photoshop, Illustrator, etc. Such activities are prohibited by
federal law and are thus not allowed in any form on IDT. Such prohibition also
includes the unauthorized copying of copyrighted material including, but not
limited to, digitization and distribution of photographs from magazines, books,
or other copyrighted sources and copyrighted software. The exportation of
software or technical information in violation of U.S. Export control laws is
strictly prohibited.

      14. High-Traffic web sites. Individual accounts on IDT machines are
intended to provide access to individuals only. As most individual pages are
fairly low-traffic for the most part, the performance for everybody on the
systems is optimal. However, some individuals occasionally choose to put content
on their pages which draws a large number of hits to their pages and thus
degrade performance for other users' page. Due to this,
<PAGE>   42

IDT has had to implement certain limitations on the amount of traffic an
individual user's home page can receive. Typically a page can safely receive
around 4-5,000 hits per day and/or transfer under 20-25 megs per day without
causing excessive load on the host system. Sites generating more than this must
be moved over to Web Services where they are better able to deal with the extra
traffic.

      15. In an effort to control multiple logins and offer all of our customers
an equal chance to get on-line, users are permitted only one active session
running at a given time. If users require multiple sessions simultaneously, IDT
requires that the user obtain additional accounts. Violators are subject to
immediate termination without warning, as IDT sees fit.

      16. If IDT discovers an objectionable 'spam' making reference to either an
IDT hosted web site or e-mail address, regardless of where the spain originated
from, IDT reserves the right to remove the e-mail address, web site or
objectionable material from its servers.

      V. PENALTIES FOR ABUSE

      A. All prohibited activities are subject to immediate termination of a
user's account and any and all criminal and civil penalties available under the
law. The penalties imposed on a user for abuse will vary based on the level of
the offense. Typically the user will receive a warning on the first offense.
However, if the offense is severe enough, IDT reserves the right to disable the
account immediately. Accounts that have been disabled by administration for
abuse will not be re-opened for a user. It is vital for IDT to provide a quality
service for all users, and IDT will not tolerate users who through their actions
hinder us in that endeavor. It is also important for IDT to have a non-intrusive
presence to the rest of the net, and thus prohibited activities that adversely
affect users on the other service providers and their associated networks. To
this end, IDT reserves the right to modify and/or disable user's service at any
such time abuse occurs.

      B. IDT will not reimburse users whose service was suspended or disabled
due to any of the reasons listed above.

      C. All IDT Internet users agree to indemnify, waive and hold IDT, its
officers, directors, shareholders, employees, agents, subsidiaries and
affiliates harmless from any and all claims and expenses related to the user's
violation of this agreement, including any abusive or unlawful behavior on the
part of the user or anyone using the user's account, or the infringement of any
intellectual property or privacy rights of any person or entity. This means that
you cannot sue or recover damages whatsoever from IDT as a result of IDT's
decision to remove material from its servers, warn you, suspend or terminate
your account or take any other action during the investigation of a suspected
violation or as a result of IDT's conclusion that a violation has occurred.

      D. You agree to defend, indemnify and hold IDT harmless form any claims,
losses
<PAGE>   43

and damages, including attorney's fees, resulting form your violation of any
provisions of this agreement, with or without your knowledge or consent. IN NO
EVENT SHALL IDT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, PUNITIVE OR
OTHER CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO LOST PROFITS) ARISING
OUT OF VIOLATIONS OF THIS AGREMEENT OR THE ACCOUNTHOLDER'S USE OF OR INABILITY
TO USE IDT'S SERVICES. IDT'S ENTIRE LIABILITY AND YOUR EXCLUSIVE REMEDY SHALL BE
AT IDT'SELECTION, EITHER RETURN OF SERVICE FEES PAID OR REPLACEMENT OF
CONNECTION SERVICE OR PRODUCTS.

      VI. ADDITIONAL POLICIES

      A. Due to the explosive growth of the Internet and the constant addition
of new services and thus the new possibilities of abuse, IDT reserves the right
to add and enforce new policies.

      B. While IDT strives to provide local access to our Accountholders, IDT
cannot guarantee such service. It is the user's responsibility to verify with
the telephone carrier whether the calls made via the Accountholder's modem to
access the Internet are local or not. IDT makes no warranties as to whether IDT
can provide users with local Internet access numbers. Users are responsible for
paying their own dial-up telephone charges for accessing the Internet, as well
as for contacting IDT's Accountholder and/or Technical Support lines. IDT WILL
NOT REIMBURSE USERS FOR ANY LONG DISTANCE CHARGES.

      VII. LIMITATION OF LIABILITY

      THE IDT INTERNET SERVICE IS PROVIDED ON AN AS IS, AS AVAILABLE BASIS. NO
WXRRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THOSE OF
MERCHANTIBILITY OR FITNESS FOR A PARTICULAR PURPOSE, ARE MADE WITH RESPECT TO
IDT INTERNET OR ANY INFORMATION OR SOFTWARE THEREIN. UNDER NO CIRCUMSTANCES,
INCLUDING NEGLIGENCE, SHALL IDT INTERNET SERVICE BE LIABLE FOR ANY INCIDENTAL,
SPECIAL, OR CONSEQUENTIAL DAMAGES THAT RESULT FROM THE USE OF OR INABILITY TO
USE IDT INTERNET. NOR SHALL IDT INTERNET BE RESPONSIBLE FOR ANY DAMAGES
WHATSOEVER THAT RESULT FROM MISTAKES, OMISSIONS, INTERRUPTIONS, DELETION OF
FILES, ERRORS, DEFECTS, DELAYS IN OPERATION OR TRANSMISISON, OR ANY FAILURE OF
PERFORMANCE WHETHER OR NOT CAUSED BY EVENTS BEYOND IDT'S REASONABLE CONTROL,
INCLUDING BUT NOT LIMTIED TO ACTS OF GOD, COMMUNICATIONS LINE FAILURE, THEFT,
DESTRUCTION, OR UNAUTHORIZED ACCESS TO IDT RECORDS, PROGRAMS, OR SERVICES. IN NO
EVENT SHALL IDT'S TOTAL LIABILITY FOR ALL DAMAGES, LOSSES, AND CAUSES OF ACTION
EXCEED THE AGGREGATE DOLLAR AMOUNT PAID UNDER THE AGREEMENT.
<PAGE>   44

      VIII. BILLING POLICIES

      1. Accountholder acknowledges, agrees and assumes full responsibility for
making timely full monthly payments for each IDT Internet Account. Timely
payment includes maintaining Accountholder's billing information given to IDT
for each Internet Accounts which the Accountholder must keep current. Those
Accountholders who choose to make payment with credit cards must provide IDT
with their full name, billing address, credit card number and expiration date.
It is the Accountholder's responsibility to timely notify IDT of any changes in
its credit card account. Payment for an IDT Internet account or services by
fraudulent means will result in immediate and permanent termination of the
account and possible criminal penalties.

      2. There is a $20.00 service charge for each returned check.

      3. IDT reserves the right to cancel any Accountholder account without
notice due to non-payment. In the event that Accountholder fails to timely make
full payment of each invoice, IDT reserves the right to charge interest, late
fees and/or reactivation charges on the delinquent Accountholder's account.

      4. In the event of cancellation by Accountholder, Accountholder must
contact IDT in one of the following manners:

      a. Via mail with proof of receipt properly addressed to: IDT Accountholder
Service, Attention: Internet Cancellation Department, 294 State Street,
Hackensack, New Jersey 07601; or

      b. Via e-mail to help@idt.net where the subject should have the words
"Account Cancellation"; or

      c. via telephone to an IDT Accountholder Service Representative at: (201)
883-2000, followed by written confirmation by Accountholder with proof of
receipt, properly addressed to and received by IDT within ten (10) days from the
date of telephone cancellation. Notification of cancellation MUST be accompanied
by the Accountholder's IDT login name in order for a cancellation to be
effectuated.

      5. NON-USAGE OF AN ACCOUNT IS NOT PROOF OF CANCELLATION OF SERVICE.
Accountholders are responsible for full payment on all accounts whether or not
the account is ever utilized. All original unopened software must be returned to
IDT in order for Accountholder to be entitled to any refund. In the event that
Accountholder fails to return the original unopened software to IDT,
Accountholder will be billed for a minimum of one month's service.

      6. In the event of cancellation between the lst-l5th of a month,
Accountholder will be responsible for payment of one-half(l/2) of the current
month's monthly charges.

<PAGE>   45

      7. Any billing discrepancies shall be presented to IDT in reasonable
detail, in writing, within twenty (20) days of the date of the charge. Such
notification shall not relieve Accountholder of the obligation to make all
payments including the amounts disputed by the due date. IDT shall not be
obligated to consider any Accountholder notice of billing discrepancies which
are received by IDT more than twenty (20) days following the date of the invoice
in question. If an Accountholder fails to dispute any charge after twenty (20)
days from the date of the charge, Accountholder waives its rights to thereafter
make any such dispute and all such charges will be deemed valid.

      8. In the event that an Accountholder pre-pays for their Internet account,
any discounts given by IDT for such payment plans are calculated that the
Accountholder is paying for the regular months of service and getting additional
months at the end of the service term at a discount. In the event that an
Accountholder cancels their service within a year, such Accountholder is no
longer entitled to any discounts.

      9. Accountholder acknowledges, agrees and assumes full responsibility to
verify that the telephone number that they call to access the Internet is a
telephone number which is local to their area. IDT is NOT responsible in any way
for any telephone charges incurred by any Accountholder when accessing the
Internet or when contacting IDT for any reason. In the event that the
Accountholder's local telephone number to access the Internet is out of service,
Accountholder assumes full responsibility for all long distance charges incurred
by Accountholder if Accountholder chooses to call a long distance telephone
number to access the Internet, even if directed to do so by IDT's
accountholder/Technical Support.

      10. IDT makes no warranties as to the availability or right to use of any
login name, E-mail address, or web page address. Login names, E-mail addresses
and web page addresses are NOT confirmed at the time of sign-up of any
Accountholder. IDT will not refund any charges for reprinting of stationary or
any other losses incurred.

      11. IDT MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE ACCURACY OF
BILLING, OR THE QUALITY OF SERVICES PROVIDED OR TO THE WARRANTY OF
MERCHANTIBILITY OR TO FITNESS FOR A PARTICULAR PURPOSE.

      12. Accountholder agrees that at the end of the term of the Internet
account initially agreed to by Accountholder or any term thereafter, IDT may, at
its sole discretion, automatically renew such Internet account for an additional
term. Accountholder further agrees that upon renewal of such Internet account,
IDT may continue to charge Accountholder's credit card or seek other form of
payment from Accountholder, for which Accountholder shall be responsible for. In
the event that Accountholder does not wish IDT to automatically renew such
Internet account, it is Accountholder's sole responsibility to notify IDT of
such intent prior to the expiration of such term.
<PAGE>   46

      13. All policies stated herein are subject to change at IDT's sole
discretion. Accountholder shall be responsible for adhering to any new policies
implemented by IDT.
