                                 AMENDMENT NO. 1

                       DIAL UP NETWORK SERVICES AGREEMENT

        This amendment (the "Amendment") to the Dial Up Network Services
Agreement between BBN Planet Corporation and i-Pass Alliance Inc. dated October
15, 1996 (the "Agreement") revises certain terms and conditions in the
Agreement.

The parties agree to amend the Agreement as follows:.

1. Delete Section 1.6 "Term" and substitute the following:

        1.6 "Term" shall mean the period beginning on the Commencement Date and
        extending until December 31, 1997.

2. Delete Section 5.2 Customer Committed Hours and replace with the following:

        5.2     Customer Committed Hours. Customer understands and agrees that
                it is obligated to pay for the minimum number of hours of
                Network Access Service specified as Customer Committed Hours as
                set forth in Exhibit C. Section A.2. Based on the Customer
                Committed Hours amount, BBN Planet will invoice Customer for BBN
                Basic Services at the hourly rate set forth in Exhibit C,
                Section A.1. Customer acknowledges and understands that it is
                obligated to pay the full amount due for the Customer Committed
                Hours notwithstanding the fact that cumulative actual network
                access service connect hours during the Term may be less than
                the Customer Committed Hours amount. In such event, Customer
                agrees to pay an amount which is the difference between (a) the
                total amount due for the Customer Committed Hours at the Local
                Access Service rate less (c) the amount due for actual network
                Access Service connect hours at the Local Access Service rate.
                Such amount is due and payable within thirty days of the last
                day of the Term.

3. Delete Section 8.1 Term and replace with the following:

        8.1 Term. The Term of this Agreement shall begin on the Commencement
        Date and extend until December 31, 1997.

4. Delete Exhibit C. Prices and substitute the revised Exhibit C as set forth in
Attachment No. 1 to this Amendment.

5. Change all references to "BBN Planet Corporation" in the Agreement to "BBN
Planet, a division of BBN Corporation.

6. Other Matters

        6.1 BBN Planet Engineering Activities. BBN Planet agrees to carry out
the following engineering activities for the benefit of Customer:

                                      15.
<PAGE>   16

                6.1.1 BBN Planet agrees to implement additional "redundancy" of
                DiaLinx user authentication by adding to BBN Planet's RADIUS
                authentication procedure the capability to utilize a second or
                backup i-Pass RADIUS Server if Customer's primary RADIUS Server
                is unavailable. This capability will be delivered to i-Pass by
                4/15/97. Cost: [*]. Until BBN Planet delivers this
                "redundancy" capability, BBN Planet and i-Pass will implement a
                mutually agreeable interim, low cost solution by 1/31/97.

                6.1.2 BBN Planet will identify at the time of user authorization
                any user accessing the BBN Planet dial network via the 800
                number. BBN Planet will provide a new attribute in the
                authentication request packet that will flag the call as an
                "800" access call. It will the responsibility of the i-Pass
                end-user RADIUS server to use this information in conjunction
                with the account name and password to authorize or deny access.
                This capability will be delivered to i-Pass by 4/30/97. Cost:
                [*]. Until BBN Planet delivers this "800 Identification"
                capability, BBN Planet and i-Pass will implement a mutually
                agreeable interim, low cost solution by 1/31/97.

                6.1.3 i-Pass desires that BBN Planet provide "real-time"
                disconnect data for each user. Ascend Communications has advised
                BBN Planet that it plans to include an enhancement to track and
                pass real-time disconnect data in the next version of the
                Ascend software, Version 5.0. BBN Planet will provide the per
                user session information in real-time via RADIUS accounting
                packets to i-Pass, i-Pass is responsible to modify its RADIUS
                servers to support a new accounting server attribute in each
                user profile. Expected availability of Ascend software Version
                5.0 on our network is April-May `97. BBN Planet will provide the
                information on the specification to support this feature to
                i-Pass by February 28, 1997. BBN Planet shall have no obligation
                to provide "real time" disconnect data in the event that the
                next version of Ascend does not include the capability to track
                and pass real-time disconnect data as noted above.

                6.1.4 BBN Planet and i-Pass agree to limit the number of realms
                assigned to i-Pass and to establish a naming convention which
                uniquely identifies BBN Planet's customers and i-Pass'
                customers. On a reasonable efforts basis, BBN Planet and i- Pass
                will implement a mutually agreeable approach for accomplishing
                these objectives by 4/1/97. Until this approach is implemented,
                BBN Planet will continue to support i-Pass' realm requirements
                and its current naming convention.

                6.1.5 Consideration. In consideration for BBN Planet's agreement
                to undertake the engineering activities as described in
                Paragraphs 6.1.1 and 6.1.2 above, Customer agrees to make a
                nonrefundable prepayment of [*] (for 6000 hours of Local
                Access Service) for the aforementioned engineering activities as
                described above (i.e, a total of [*]) which amounts are
                due and payable within fifteen days of the completion of each

                activity. These amounts will be credited against amounts due and
                payable under Section 5. for BBN Planet Basic Services.

        6.2 Dialinx Pricing Assurance. If BBN Planet agrees to provide BBN
        Planet Basic Services to one or more of the following competitors of
        Customer ("Competitors") at prices (based on substantially similar
        Customer Committed Hours, terms and conditions) which are less than
        those granted to Customer under this Agreement, BBN Planet will so
        advise Customer. BBN Planet may elect, but shall have no obligation, to
        offer revised prices to Customer which are comparable to those offered
        to a Competitor. In the event that BBN Planet elects not to offer
        revised prices to Customer, Customer shall have the right to terminate
        this Agreement at its convenience. If Customer elects to so terminate,
        Customer's obligation under Section 5.2 Customer Committed Hours (as set
        forth in the Agreement as amended) shall expire.

        Competitors of Customer are as follows:

        [List no more than two companies]: AimQuest, EUnet AimQuest, EUnet

During the Term Customer shall have the right to add up to four additional
companies to the above list upon delivery of written notice to BBN Planet.

        6.3 BBN Planet Marketing Support

                6.3.1 To facilitate Customer's sales efforts, BBN Planet will
                carry out the marketing support activities as described in
                Attachment No. 2.

                6.3.2 In the event that BBN Planet fails to complete any of the
                Marketing Support activities as described in Attachment No. 2,
                BBN Planet will reduce the Customer Committed Hours amount as
                set forth in Exhibit C (as revised) by the amount of hours set
                listed in Attachment No. 2.

All other terms and conditions in the Agreement remain unchanged.

                     EXHIBIT C FOR DIALINX SERVICE FOR IPASS
--------------------------------------------------------------------------------

This Exhibit C shall supercede the Exhibit C in the Dial-Up Network Services
Agreement dated December 21, 1998 ("Agreement") and any amendment thereto,
provided, however, that all fees for services delivered prior to the execution
of this revised Exhibit C are still due.

1.      Pricing Summary: This section highlights the general elements of pricing
        and commitments:

1.1     Network Access. You will be billed for each end user that may access the
        GTE Internetworking DiaLinx network ("North American Network") in
        accordance with the pricing options set forth herein. You will be
        charged for Network Access, which, for each calendar month, shall be the
        greater of either (a) Access charges due in accordance with Section 5
        "Rates and Charges" or (b) Monthly Customer Commitment as set forth in
        Section 2 "Minimum Monthly Commitment".

        1.2     Monthly Customer Commitment: In return for volume discounts
                (inherent in the prices stated below) you have agreed to use a
                minimum dollar volume of network access in each month of the
                agreement ("Monthly Customer Commitment"). In the event that
                your actual network access charges do not meet the Monthly
                Customer Commitment, you will be billed for the applicable
                Monthly Customer Commitment (the difference between you actual
                network access usage and the Monthly Customer Commitment is the
                "Commitment Payment")

        1.3     Term Commitment: The aggregate of the Monthly Customer
                Commitment is [*] ("Term Commitment"). In the event your
                actual network access charges exceeds the Term Commitment all
                subsequent Monthly Customer Commitment obligations shall be
                suspended.

        1.4     If, at the end of each twelve (12) month period, your actual
                network access charges exceeds [*] ("Annual Commitment") and you
                have paid a Commitment Payment, you will be credited either (a)
                the amount Customer has exceeded the Annual Commitment or (b)
                the applicable Commitment Payment, whichever is less.

                For example:
                If Customer's actual network access charges reached [*] in month
                12 and during that same period Customer made one Commitment
                Payment of [*], then Customer shall be issued a credit equal
                to [*]. (Example One)

                If Customer's actual network access charges reached [*] in month
                12 and Customer had never made a Commitment Payment, then
                Customer shall not be issued a credit in this example. (Example
                Two)

2.      Minimum Customer Commitment. During the Service Period, in return for
        discounts inherent in the pricing outlined therein, you have agreed to
        use a minimum dollar volume of network access in the amount of
        two-hundred-thousand-dollars ([*] per month, after discounts, of
        the agreement ("Minimum Customer Commitment"). In the event that Network
        access charges do not meet the Minimum Customer Commitment you will be
        billed for the difference between the amount actually charged within the
        given month and the Minimum Customer Commitment.

3.      Commencement Date: The terms and conditions of this Exhibit C shall be
        applied to charges assessed in the month of December (1999) if the
        Agreement is executed on or before December 17, 1999. In the event this
        Agreement is executed after December 15, 1999, the terms and conditions
        of this Exhibit C shall be applied to charges assessed in the month of
        January (2000).

4.      Service Period. The Service Period shall be thirty-six (36) full
        calendar months.

5.      Rates and Charges: All rates and charges for the services defined in
        this Section 5. All network connect time is rounded up to the next
        highest minute and billed in one minute increments. Invoices are issued

                Users accessing the DiaLinx Network exceeds the thresholds in
                the table below, the applicable Rates for that month will be
                reduced to the corresponding Rates.

                Per-User Rates are available on a thirty (30) hour plan, based
                on the average use of all active users in any given month. For
                example: If Customer has 200 users access the DiaLinx Network
                the total allowable hours is [*] (or 200 Users x 30 Hour Plan).

                        the violation is of a nature that disrupts the network

customers of this Acceptable Use Policy and for enforcing its restrictions with
regard to their customers' actions.

Complaints about customers of any such reseller or downstream service provider
shall be forwarded to such reseller or downstream service provider for
resolution. If at time GTE Internetworking determines that such reseller or
downstream service provider is not taking appropriate action in accordance with
this Acceptable use Policy, GTE Internetworking shall work with such reseller or
downstream service provider to review their policies and enforcement procedures.
If the reseller or downstream service provider continues to fail to take
appropriate action, GTE Internetworking will take such further action as it
deems appropriate, up to and including termination proceedings.

civil liability. GTE Internetworking may refer violators to civil or criminal
authorities for prosecution and will cooperate fully with applicable government

store any information, data, or material which:

o     Infringes any copyright, trademark, trade secret, or other intellectual
      property right.

      to civil liability.

In the event of suspected, alleged, or actual illegal activity, GTE
Internetworking will notify or cooperate with applicable law enforcement
authorities for potential civil or criminal investigation or prosecution.

B.      ABUSE

The following general actions are considered "abuse" and are strictly
prohibited:

Any conduct which violates the accepted norms and expectations of the Internet
community at large (whether or not detailed in this Acceptable Use Policy). GTE
Internetworking reserves the

                                       4
<PAGE>   40
right, in its sole discretion, to make a determination whether any particular
conduct violates such norms and expectations.

Resale of GTE Internetworking's services or products, unless expressly
authorized in a separate written agreement with GTE Internetworking.

o       Any conduct that restricts or inhibits any other user, whether a
        customer of GTE Internetworking or a user of any other system or
        network, from using or enjoying any of GTE Internetworking's services or
        products, as determined by GTE Internetworking in its sole discretion.

o       Harassment, whether through language, frequency, or size of messages.

o       Creating, forwarding, posting, or distribution of chain messages of any
        type (also known as "pyramid" or "Ponzi" schemes).

o       Forging of message headers or a sender's identity, or taking any similar
        action with the intent of bypassing restrictions or limits on access to
        a specific service or site (such as a moderated newsgroup or a site
        utilizing filters). This prohibition does not restrict the legitimate
        use of aliases or anonymous re-mailers.

o       Falsifying identity or contact information (whether given to GTE
        Internetworking, to the InterNIC, or put in a message header) to
        circumvent this Acceptable Use Policy. This prohibition does not
        restrict the legitimate use of aliases or anonymous re-mailers.

o       Furnishing false or incorrect data to GTE Internetworking on written or
        online applications, contracts, or other materials or formation provided
        to GTE Internetworking, including fraudulent use of credit card numbers
        or "bill to" telephone numbers.

o       Attempting to circumvent or alter the processes or procedures to measure
        time, bandwidth utilization, or other methods to document use of GTE
        Internetworking's products and services.

C.      SECURITY

Violations of system or network security are prohibited, and may result in
criminal and civil liability. GTE Internetworking will investigate potential
security violations, and may notify applicable law enforcement agencies if
violations are suspected.

It is strictly prohibited to attempt to circumvent the authentication procedures
or security of any host, network, network component, or account (i.e.,
"cracking") to access data, accounts, or servers which the user is not expressly
permitted or authorized to access. This prohibition applies whether or not the
attempted intrusion is successful, and includes unauthorized probes or scans
performed with the intent to gather information on possible security weaknesses
or exploitable configurations.

Users of the GTE Internetworking Network are responsible for educating
themselves and configuring their systems with at least basic security. Should
systems at a user's site be violated,

                                       5
<PAGE>   41
the user is responsible for reporting the violation and then fixing the
exploited system. For instance, should a site be abused to distribute unlicensed
software due to a poorly configured FTP (File Transfer Protocol) Server, the
user is responsible for re-configuring the system to stop the abuse.

Users are prohibited from interfering or attempting to interfere with service to
any other user, host, or network on the Internet ("denial of service attacks").
Examples of such prohibited activity include without limitation (a) sending
massive quantities of data (i.e., "flooding" with ICMP, SMTP, or any other type
of traffic that exceeds accepted norms of size and/or frequency) with the intent
of filling circuits, overloading systems, and/or crashing hosts, (b) attempting
to attack or disable any user, host, or site, or (c) using, distributing, or
propagating any type of program, script, or command designed to interfere with
the use, functionality, or connectivity of any Internet user, host, system, or
site (for example, by propagating messages, via e-mail, ______ posting, or
otherwise, that contain computer worms, viruses, control characters or Trojan
horses).

Users are prohibited from intentionally or negligently injecting false data into
the Internet, for instance in the form of bad routing information (including but
not limited to the announcing of networks owned by someone else or reserved by
the Internet Assigned Numbers Authority) or incorrect DNS information.

D.      E-MAIL

mail ("e-mail") over the Internet. Without limitation of the foregoing, it is
strictly prohibited to engage in any of the following activities:

o     Sending unsolicited bulk e-mail ("UBE", or "spamming"). This includes, but
      is not limited to, the distribution of UBE for commercial, informational,
      advertising, political, or religious purposes.

o     Setting up "mailback" or "drop box" addresses in order to receive
      responses from UBE, either directly by the user or by a third party on
      behalf of the user.

o     Using a mail transport agent (MTA) outside of a user's own site to relay
      mail (unless a user has received express permission to do so). Even if
      permission has been received, users are prohibited from forging their
      identities to make it appear as though the e-mail sourced from the relay.

o     Sending UBE, or posting news, to advertise or promote resources whose
      connectivity depends in any way on the GTE Internetworking Network,
      regardless of whether such UBE or news posting is made using the GTE
      Internetworking Network. For example, using another ISP's services to send
      UBE which advertises a web page hosted by or via the GTE Internetworking
      Network is prohibited.

o     Hiring or using any third party service for the purpose of distributing
      UBE or excessively "multi-posting" or "cross-posting" any ______ posting
      in the name of a user. Users will be

                                       6
<PAGE>   42

      held responsible for the actions of any third party agent that acts on
      behalf of or for the benefit of the user, and such users shall be held
      directly accountable for any violations of this Acceptable User Policy by
      such third party agent.

o     Bulk e-mail may be sent only to recipients who have expressly requested
      receipt of such e-mail. Users that send solicited bulk e-mail are required
      to maintain records of all bulk e-mail subscription requests, and to
      provide GTE Internetworking with such records upon request of GTE
      Internetworking, to enable GTE Internetworking to investigate complaints
      from third parties. The sender of any solicited bulk e-mail shall, upon
      the request of a recipient, immediately remove such recipient from all
      applicable mailing lists and refrain from further transmissions of e-mail
      to such recipient.

o     Use of any auto-responder messages, mailing lists, or any other programs
      or scripts run by a user to handle or re-distribute e-mail is the sole
      responsibility of the user, and shall be operated in a reasonable manner.
      This responsibility includes, but is not limited to, maintaining
      up-to-date mailing lists to minimize mail bouncing and to facilitate the
      processing of removal requests, configuring auto-responders so that they
      do not create mail loops, and the prompt handling of any complaints
      regarding UBE re-distributed through a mailing list onsite.

E.      UNSENET (ALSO KNOWN AS NETNEWS OR NEWSGROUPS)

GTE Internetworking recommends that users not post to any newsgroup until they
have familiarized themselves with the subjects, established guidelines, and
restrictions of such newsgroup. All Usenet guidelines and restrictions are
incorporated herein by reference, and users of the GTE Internetworking Network
agree to adhere to such guidelines unconditionally.

Without limitation of the foregoing, it is strictly prohibited to engage in any
of the following activities:

o     Making any posting for commercial purposes (including without limitation
      the pointing to specific URLs for commercial purposes), except where such
      postings are expressly permitted under the charter and/or Frequently Asked
      Questions (FAQ) of an applicable newsgroup.

o     Posting binary files to newsgroups whose charter or name does not include
      allowances for such files.

o     Posting via GTE Internetworking's newsfeed any solicitation for mailback
      to an e-mail address (including addresses of non-GTE Internetworking
      users) networks with the intention of bypassing this Acceptable Use
      Policy.

o     Canceling newsgroup posting other than their own, or using auto-responders
      or cancel-bots (or similar automated or manual routines) which generate
      excessive network traffic or disrupt Usenet newsgroup/e-mail use by others
      (except in cases of official newsgroup moderators performing their
      duties).

                                      7
<PAGE>   43

o     Engaging in "Excessive Cross-Posting" (ECP) or "Excessive Multi-Posting"
      (EMP) or "Usenet spam" (no matter what the content might be) as defined by
      the Internet community and expressed in the news.admin.net-abuse."
      Newsgroups and FAQs.

o     Disrupting newsgroups with materials, postings, or activities that are (as
      determined by GTE Internetworking in its sole discretion) frivolous,
      unlawful, obscene, threatening, abusive, libelous, hateful, excessive, or
      repetitious, unless such materials or activities are expressly allowed or
      encouraged under the newsgroup's name, FAQ, or charter.

o     Using filtering messages (e.g., NoCoM) in an intrusive manner, or at other
      than the user's server level. Generally, filtering messages are considered
      normal Usenet traffic and are treated as such by GTE Internetworking.
      Complaints regarding filter use or abuse should be directed either to the
      source generating them or the sites utilizing them.

o     Performing any authorized creation, cancellation, or removal of
      newsgroups.

The legitimacy of a given post or cancellation is determined by the official
newsgroup or mailing-list moderator. Therefore, GTE Internetworking defers to
their judgment on these issues. If no such official entity exists, it is at GTE
Internetworking's discretion to determine whether any post or cancellation is
complaint with this Acceptable Use Policy and Internet community standards for
that newsgroup.

F.      WORLD WIDE WEB

GTE Internetworking strictly prohibits users from engaging in any of the
following web-related activities:

o     The exploitation or attempted exploitation of any scripts presented on web
      pages (e.g., forms for answering questions or for entering data).

o     Excessive use of bandwidth by utilizing programs, scripts, or commands to
      abuse a web site (for example, by connecting for an excessive amount of
      time, repeatedly engaging site-local scripts, or related behavior).

o     "Walking" a database for the purpose of collecting data contained therein
      (whether or not this behavior requires that the reader of the page must
      knowingly ignore files such as "robot.txt" which is designed to guide
      cataloguing robots/programs).

o     Operating a robot on a site's page after the site has asked that the
      behavior cease.

o     Configuring a web page to act maliciously against users that visit that
      web page.

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS,
HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO RULE 406 OF THE SECURITIES ACT OF 1933, AS AMENDED.

                                                                   EXHIBIT 10.11

                   VIRTUAL INTERNET PROVIDER (VIP) AGREEMENT

This Agreement is made in the city of Fairfax, Virginia, this 9th day of January
1997, between UUNET Technologies, Inc., whose address is 3060 Williams Drive,
Fairfax, Virginia 22031 (UUNET), and i-Pass Alliance Inc., (Reseller), whose
address is 650 Castro Street, Suite 280 Mountain View, CA 94041.

The parties hereto agree and bind themselves as follows:

1. SERVICE. UUNET will sell, and Reseller will purchase, telecommunications
services for the interconnection of Reseller's end users with the Internet.
Reseller is responsible for all end-user customer support, billing, and
collections. UUNET's relationship under this Agreement is solely with Reseller
and not with any of reseller's end users. UUNET agrees that its
telecommunications services provided to Reseller will be of a quality usual and
customary in the industry for similarly situated companies. Although it is
understood that UUNET cannot guarantee continuous service, UUNET agrees to
provide prompt reparation of any disruption in services to the extent reasonably
possible consistent with its obligations to other customers. To this end, UUNET
agrees to provide Reseller with a toll-free number to report problems relating
to network integrity. This number is to be used only by Reseller and will not be
released to Reseller's customers.

2. PRICING. For PPP dial-up traffic (analog dial, 28.8Kbps and ISDN) and VIP
radius server interoperability, the prices contained in Schedule A apply. For
all other services, UUNET's list prices apply unless other prices have been
specifically established.

3. TERMS AND CONDITION. Reseller agrees to comply with the Network Services
Terms and Conditions contained in Schedule B. It further agrees to require its
end users to comply with terms and conditions in substance identical to those in
Sections One and Two of Schedule B. Reseller shall defend, indemnify, and hold
harmless UUNET against any claims resulting from Reseller's use of UUNET's
services, or that of its customers throughout its chain of distribution.

4. PUBLICITY. The prices and terms of this Agreement shall be held confidential
by both parties. Neither party shall publicize the existence of this agreement
without the consent of the other, and in the event of such agreement, all press
release materials shall be reviewed and approved by the other party.

5. TECHNICAL AGREEMENT. Reseller agrees to comply with the Technical Agreement
for Network Interoperability, attached as Schedule C.

6. TERM. The term of this Agreement is one year from the date of contract
signature, which term shall be automatically renewed for additional one year
terms, provided that neither party has delivered to the other party a written
notice of intent not to renew for the forthcoming term. Such notice of intent
shall be given not less than sixty (60) days in advance of the end of the
current term.

7. TERMINATION. Either party may terminate this Agreement for cause without
penalty in the event that the other party hereto breaches any material term of
this Agreement. Prior to such termination, the party intending to terminate
shall first give the other party written notice of its

intent to terminate which shall clearly describe problem(s) constituting cause.
The other party will have thirty (30) days from the date of receipt of such
notice to correct the problem. If the problem is not corrected within such
period, the party intending to terminate may terminate this Agreement on such
30th day. However, if Reseller shall violate the acceptable use policy in
Section 2 of Schedule B, or permit such violation, and does not immediately act
to remedy such violation when it becomes aware of it, UUNET may terminate this
Agreement without penalty with ten (10) days written notice. If any amounts due
and owing by Reseller remain unpaid sixty (60) days after date of invoice, then
UUNET may terminate this Agreement immediately upon written notice without
penalty.

8. TESTING. The full effectiveness of this contract will be contingent upon the
completion of technical testing to the mutual and reasonable satisfaction of
both parties during the period of thirty (30) days following execution of this
Agreement. If either party shall reasonably declare the testing results to be
unsatisfactory at the conclusion of this thirty (30) day period, then the
parties shall have another ten (10) days to correct the problem. If such
correction is not completed to the mutual and reasonable satisfaction of the
parties then this Agreement will terminate with not further liability to either
party. If no such declaration is made, acceptance of technical testing shall be
presumed, and the contract shall remain in effect. Monthly minimums will begin
to accrue from the date of the satisfactory completion of technical testing. If
testing is completed during the course of a month, the first month's minimum
commitment will be prorated to reflect the shortened month.

9. LIMITATION OF LIABILITY. NOTWITHSTANDING ANYTHING ELSE TO THE CONTRARY
STATED OR IMPLIED HEREIN, NEITHER PARTY SHALL HAVE ANY LIABILITY WHATSOEVER FOR
ANY INCIDENTAL CONSEQUENTIAL OR SPECIAL DAMAGES SUFFERED BY THE OTHER OR BY ANY

                                   SCHEDULE B

                    NETWORK SERVICES VIP TERMS AND CONDITIONS

1. UUNET exercises no control whatsoever over the content of the information
passing through UUNET. Except as otherwise provided for in Section Ten of the
Network Services Agreement attached hereto, UUNET makes no warranties of any
kind, whether expressed or implied, for the service it is providing. UUNET also
disclaims any warranty or merchantability or fitness for a particular purpose.
UUNET will not be responsible for any damage Reseller suffers. This includes
loss of data resulting from delays, nondeliveries, misdeliveries, or service
interruptions caused by Reseller's own negligence or Reseller's errors or
omissions. Use of any information obtained via UUNET is at the user's own risk.
UUNET specifically denies any responsibility for the accuracy or quality of
information obtained through its services.

2. UUNET's network may be used only for lawful purposes. Use of UUNET's network
for lawful commercial purposes is both permitted and encouraged. Transmission of
any material in violation f any applicable law is prohibited. This includes, but
is not limited to: copyrighted material, material which is threatening or
obscene, or material protected by trade secret. Any access to other networks
connected to UUNET's network must comply with the rules appropriate for the
other network. Reseller agrees to indemnify and hold harmless UUNET from any
claims resulting from Reseller's use of the service or the use of the service by
any of Reseller's customers or others throughout Reseller's chain of
distribution, including end users, which damages UUNET or another party.

3. Resale to other individuals and organizations is permitted, but they may not
further resell the services.

4. Payment is due thirty (30) days after date of invoice. Accounts are in
default if payment is not received within thirty (30) days after date of
invoice. Accounts unpaid sixty (60) days after date of invoice may have service
interrupted. Such interruption does not relieve Reseller from the obligation to
pay the monthly charge. Only a written request to terminate service relieves it
of the obligation to pay the monthly account charge. Accounts in default are
subject to an interest charge of one-and-one-half percent (1.5%) per month on
the outstanding balance. If Reseller's state does not allow an interest rate of
one-and-one-half-percent (1.5%), then the maximum allowable rate will be
charged. Reseller agrees to pay UUNET its reasonable expenses, including
attorney and collection agency fees, incurred in enforcing UUNET's rights under
this Agreement for money due and owing.

5. These Terms and Conditions supersede all previous representations,
understandings or agreement sand shall prevail notwithstanding any variance with
terms and conditions of any order submitted. Use of UUNET's network constitutes
acceptance of these Terms and Conditions.

                                   SCHEDULE C

                TECHNICAL AGREEMENT FOR NETWORK INTEROPERABILITY

1. Reseller agrees to secure a minimum 11 connection from UUNET and operate its
own Radius server. Such server will perform user validation functions, and
will be maintained in a secure environment. Reseller also will maintain this
server with reasonably current versions of the Radius protocols as provided
by UUNET.

2. Reseller agrees to use software and procedural safeguards to insure that
only accurate routing information for networks to be used by Reseller's
customers is transmitted from Reseller's Radius server into UUNET's network and
to use best efforts to immediately remedy any problems leading to transmission
of incorrect routing information.

3. Reseller agrees to assign each end user customer a unique identification
number for billing purposes, and to reasonably cooperate with UUNET in
establishing the structure of this identification number.

4. Reseller and UUNET each agree to cooperate with the other in identifying and
resolving any security infringements which involve Reseller's customers and
UUNET's network.

5. It is recognized and agreed that any billing data supplied on an interim
basis (more frequently than monthly) is an estimate and may not be relied upon
for 100% accuracy.

                                 AMENDMENT NO. 1

This Amendment No. 1 ("Amendment") to the Virtual Internet Provider (VIP)
Agreement between UUNET Technologies, Inc. ("UUNET") and I-Pass Alliance, Inc.
("Reseller"), dated January 8, 1997 ("Agreement") is made as of the date of the
second signature below.

The parties agree to add the following Sections to Schedule A of the Agreement
as follows:

5.      RADIUS ACCOUNTING AND PRICING

        UUNET will provide Radius Accounting, a method of measuring End Users'
        use of the services consisting of login and logout statistics of each
        End User, at Reseller's written request. Reseller has the sole
        responsibility to analyze these statistics to identify and investigate
        duplicate log-ins and take appropriate action. The statistics are not to
        be used as a method for calculating monthly charges for UUNET services,
        as the definitive calculation of Reseller's monthly charges will be set
        forth in the invoice provided Reseller on a monthly basis.

        The Monthly Fee for Radius Accounting will be waived for six (6) months
        from the date of the second signature below provided that monthly
        charges paid by Reseller to UUNET increase by [*] over the charges in
        the month prior to execution of this Amendment during each of the six
        (6) months in which the fee for Radius Accounting was waived. If
        Reseller does not increase its monthly charges by [*] during the six
        (6) months in which the Radius Account fee was waived, Reseller will be
        responsible for paying UUNET the amount which would have been due.

6.      VIP TOLL FREE SERVICE

        To allow Reseller's End users toll-free access to the UUNET Network, VIP
        Toll Free service is available at a fee of [*]/hour. To activate VIP
        Toll Free service, Reseller must notify UUNET in writing and provide a
        reasonably accurate forecast of the peak simultaneous users of the
        service expected in the next six months. UUNET will notify Reseller once
        VIP Toll Free service has been activated and is available to Reseller's
        End Users.

7.      INTERNATIONAL PRICING

        Price for International Access will be [*] per hour in countries in
        which UUNET has points of presence, which UUNET may change from time to
        time.

                                 AMENDMENT NO. 2

This Amendment No. 2 ("Amendment") to the Virtual Internet Provider Agreement
("VIP") between UUNET Technologies, Inc. ("UUNET") and I-Pass Alliance, Inc.
("Reseller"), dated January 9, 1997 ("Agreement") is made as of the date of the
second signature below ("Effective Date"). The Amendment also amends the
CompuServe Network Services Agreement for Managed Service Providers (MSP) dated
November 4, 1997 ("CompuServe NSA").

Whereas, the parties desire to amend the Agreement and the CompuServe NSA,

Whereas, UUNET is the successor in interest to CompuServe Network Services,
Inc., and has assumed the obligations and rights of CompuServe, Inc. under the
CompuServe NSA;

Now, therefore, in accordance with procedures for amendment of the Agreement and
the CompuServe NSA set forth therein, and in consideration of the foregoing and
the mutual agreements herein set forth, the parties hereby agree as follows:

The parties agree as follows:

1.      The parties agree to extend the term of the Agreement and the term of
        the CompuServe NSA for an additional three (3) years from the Effective
        Date of this Amendment, which terms shall hereafter remain coterminous
        and upon the expiration of such agreements shall be automatically
        renewed for an additional one year term, provided that neither party has
        delivered to the other a written notice of intent not to renew for the
        forthcoming term not less than 60 days in advance of the end of the
        then-current term.

2.      Section 7 of the Agreement shall be replaced with the following:

        This Agreement may not be terminated by either party except that either
        party may terminate this Agreement if the other party materially
        breaches the terms of this Agreement and does not cure the breach within
        sixty (60) days after receipt of written notice of such breach, which
        notice describes such breach in reasonable detail. Upon termination or
        expiration of this Agreement for any reason other than Reseller's breach
        of Reseller's payment or confidentiality obligations, at Reseller's
        request the parties shall continue to perform all of their obligations
        and maintain all of their rights under the Agreement for a phase-out
        period of thirty (30) days from the date of termination or expiration.
        However, if Reseller violates the Acceptable Use Policy in Section 2 of
        Schedule B, or becomes aware of such a violation, and in either event
        does not immediately act to remedy such violation when it becomes aware
        of it, UUNET may terminate this Agreement without penalty with thirty
        (30) days written notice, provided that service may be suspended without
        prior notice to the extent necessary for UUNET to respond to a court or
        government demand, or to preserve the integrity or normal operation of
        the UUNET Network. Reseller shall be notified promptly of any material
        suspension of service undertaken pursuant to the previous sentence.

3.      Section 1 of Schedule A of the Agreement shall be replaced with the
        following:

                                       1.

</TABLE>

4.      Section 2 of Schedule A of the Agreement shall be replaced with the
        following:

        Reseller agrees to a total Monthly Minimum Amount of [*] per month
        for dial-up Internet access services from UUNET. If in any month the sum
        of the actual charges for dial-up Internet access service under the
        Agreement and the CompuServe NSA is less than [*] then Reseller
        shall pay the applicable Monthly Minimum Amount in lieu of actual
        charges.

5.      In consideration for the Monthly Minimum Amount agreed to in Section 3
        of this Amendment, UUNET will reduce the basic Rate Per Hour set forth
        in Section 3.1 of the CompuServe NSA to [*] per hour. Surcharges and
        other fees in the CompuServe NSA shall not be modified by this
        Amendment.

6.      The following shall be included in Section 2 of the Schedule B of the
        Agreement

All use of the service or the UUNET Network shall comply with the UUNET
Acceptable Use Policy ("Policy") for the country in which the service is used,
as set forth at http://www.UU.net/terms. UUNET reserves the right to change the
Policy from time to time effective upon posting to that URL, and notice of any
such revised Policy will be included with Reseller's monthly invoice in the
month following the change. Reseller agrees to develop, maintain, and require
its customers to comply with an acceptable use policy containing terms at least
as restrictive as the Policy, as applicable, including any subsequent
modifications.

7.      Section 3 of Schedule B of the Agreement shall be replaced with the
        following:

        Notwithstanding any other provision of this Agreement, Reseller shall
        have the right to resell the Service to third parties through one or
        more tiers of subdistributors, and to grant the right to its customers
        to do the same, provided that all such customers or subdistributors
        comply with the applicable terms of this Agreement.

8.      The following shall be added as Schedule D to the Agreement.

                                   SCHEDULE D

        negligence. You acknowledge and agree that all end users must exercise
        their own due diligence before relying on any information available on

        identical to those in Schedule D of the Virtual Internet Provider
        Agreement ("VIP") between UUNET Technologies, Inc. ("UUNET") and I-Pass
        Alliance, Inc. ("Reseller"), dated January 9, 1997, as amended.

10.     The second sentence of Section 3 of the Agreement shall be deleted and

        reincorporated contingent upon the corresponding assumption by that new
        Delaware corporation of all rights and obligations under this Agreement.
