     2.   Integration.

     2.1  Integration Efforts. Content Provider will perform the necessary

including but not limited to (a) the insertion and maintenance of a Qpass "buy
link" within the Content Provider Mobile Channel linking to the e-Wallet

transactions for the purchase of Digital Content using the e-Wallet ("Qpass
System"). Based on business rules established by ATTWS, Users may purchase
Digital Content through the e-Wallet using (i) debit or credit cards ("Bill to
Card Transactions") or (ii) Bill to Phone Transactions (defined in Section 5,
below) as the payment mechanism. When commercially available, the default
payment mechanism will be Bill to Phone for Users qualified to use Bill to Phone
(as determined by ATTWS).

     3.2  Digital Products and Subscriptions. For purposes of this Agreement, a
"discrete priced product" means a product with a different price point from
other products of Content Provider or is a different type of product. For
example, games and ring tones may be different products. However, different ring
tones at the same price point will be considered the same discrete priced
product. As provided in the User Documentation, Content Provider must submit a
Content Provider Worksheet (the current version of which is attached as Exhibit
A) for each product it desires to sell through the e-Wallet. Whether or not a
product is a discrete priced product will be governed by the User Documentation.
If Content Provider desires to offer subscription services, Content Provider
must offer such subscription services for full-month terms of no less than one
full month. If the initial term of a subscription service extends beyond
one-month periods (for example, 12-month terms), the subscription services may
not automatically renew at the end of the initial term for the same length, but
may continue automatically only on a month-to-month basis.

     3.3  Pricing. Content Provider will be responsible for pricing its Digital
Content to be sold to Users through the e-Wallet; provided that no transaction
may be priced less than [*] excluding taxes or any other governmental
fees or charges ("e-Wallet Threshold"). The parties agree that ATTWS may alter
the e-Wallet Threshold on thirty days' written notice to Content Provider.
Notwithstanding the foregoing, to the extent that Content Provider charges a
subscription fee for access to Digital Content, the subscription fee that
Content Provider charges to Users of ATTWS Wireless Data Service shall be no
higher than the subscription fees charged by Content Provider to the users of
any competitor of ATTWS for the same or similar Digital Content.

     3.4  Sharing of Information. ATTWS may share the terms of this Addendum
with Qpass so that Qpass may properly perform the administration of payment for
e-Wallet transactions.

     4.   Bill to Card Transactions. The following provisions relate to Bill to
Card Transactions only.

     4.1 Billing. Billing for Bill to Card transactions through the e-Wallet
will be made to a User's credit or debit card registered with the e-Wallet and
will be posted on the credit or debit card as described in the User
Documentation. By agreeing to make its Digital Content available for purchase
through the e-Wallet, Content Provider appoints Qpass as its Digital Content
reseller for Bill to Card Transactions. In that regard, Content Provider will
not appear on User credit and debit card statements as the merchant of record.
User information contained in the e-Wallet will be provided by Users. ATTWS does
not warrant the accuracy of the information provided by the User nor does it
warrant the identity of the User.

     4.2  Collection and Settlement; Chargebacks. Qpass will collect amounts
posted to User's credit or debit card account and will remit any amounts so
collected to Content Provider, less the Transaction Fees owed to ATTWS as
described in Section 4.3 below and less any offsets for chargebacks, refunds or
credits; provided, however, neither ATTWS nor Qpass will have any obligation to
remit any amount until the earlier of (a) the payment period by which aggregate
amounts owing to Content Provider for e-Wallet purchases exceed $500, or (b) the
end of the calendar year. Settlement will be made in accordance with Qpass
billing and remittance policies in effect from time to time, which policies will
be provided by ATTWS to Content Provider.

     4.3. Transaction Fees. For each Bill to Card Transaction, Content Provider
will pay ATTWS a transaction fee of i) [*] per transaction for transactions
under $1.00 and ii) [*] of the retail price point of the transaction, excluding
taxes, surcharges or any other governmental fees or assessments, for
transactions of $1.00 or more ("Transaction Fee"). If the proceeds from a
purchase have been collected by Qpass and remitted to Content Provider, and such
proceeds are later subject to a chargeback, then Qpass will pay the applicable
chargeback fee and debit Content Provider's remittance for the portion that had
previously been remitted. Proceeds from purchases that are later refunded are
not reflected in sales revenue and no Transaction Fees are collected by Qpass.

     4.4  Payment Terms. Qpass will collect the revenue from Users for Bill to
Card Transactions. The Transaction Fee will be collected from the monthly
amounts collected from Users. Transaction Fees will be payable by Content
Provider the month that Qpass collects the proceeds from such purchases and
Content Provider will pay such Transaction Fees by allowing ATTWS to retain the
applicable Transaction Fees.

     5.   Bill to Phone Transactions. The following provisions relate to Bill to
Phone Transactions only.

     5.1  General. For purposes of this Agreement, "Bill to Phone" is the
billing functionality that allows qualified Users (as determined by ATTWS) to
purchase Digital Content through the e-Wallet, either in single transactions, on
a subscription basis or through bundles, and to have those purchases appear on
the Users' bills for Wireless Data Service. Bill to Phone may, at ATTWS' sole
discretion, appear under an ATTWS brand name and any such Bill to Phone branding
will be considered a Mark of ATTWS and subject to the restrictions on the use of
Marks contained in the Agreement. Content Provider may not sell hard goods or
any other types of goods other than Digital Content in Bill to Phone
Transactions.

     5.2  Appointment as Payment/Receiving Agent; Use of Payment Processor.
Content Provider hereby appoints ATTWS as its agent for the collection of
payments for Digital Content purchased from Content Provider in Bill to Phone
Transactions and for the remittance of such payments (subject to the provisions
below) to Content Provider.

In that regard, Content Provider agrees that:

(a)  ATTWS may, in its sole discretion, select a bank ("Payment Processor") to
     process payments from accounts of ATTWS to accounts of Content Provider in
     order to complete payment of User purchases made through Bill to Phone.
     Content Provider acknowledges and agrees that in no event will Payment
     Processor have any obligation or liability to Content Provider arising from
     Bill to Phone Transactions or payments arising from Bill to Phone
     Transactions, regardless of the form of the claim, under this Addendum, the
     Agreement, or any other agreement between or among ATTWS, Payment Processor
     and their customers, or otherwise. Without limiting the generality of the
     preceding sentence, Content Provider also acknowledges that Content
     Provider is not a third party beneficiary of any agreement between ATTWS
     and Payment Processor or between Payment Processor and customers of the
     Bill to Phone service.

(b)  Content Provider acknowledges that ATTWS does not and will not extend
     credit to Content Provider hereunder or otherwise.

(c)  ATTWS will have sole discretion as to whether, and to what extent, to
     pursue collection against a User. Content Provider may not seek payment
     directly from Users for Bill to Phone transactions, whether or not ATTWS
     pays Content Provider for such transactions and whether or not such
     transactions are subject to chargeback or reversal.

(d)  Content Provider acknowledges that ATTWS will establish a process to handle
     chargebacks and/or reversals for disputed Bill to Phone Transactions,
     Content Provider agrees that ATTWS, as agent for Content Provider for these
     purposes, may charge back or reverse prior Bill to Phone Transaction
     payments or eliminate current Bill to Phone charges from a customer's bill,
     if the User disputes such charge, is unsatisfied with the Digital Content
     for any reason or alleges that Bill to Phone Transactions were
     unauthorized. In addition, if a Bill to Phone Transaction is cleared
     through Qpass and Content Provider is paid for such transaction, but such
     Bill to Phone Transaction later turns out to be "unbillable" by ATTWS (for
     example, because the customer no longer has a valid account), then ATTWS
     may charge back any amounts paid to Content Provider. If a Bill to Phone
     Transaction is subject to charge back or reversal after this Addendum has
     terminated or expired. ATTWS will invoice Content Provider for the amount
     of such charge back or reversal and Content Provider will promptly pay such
     amount.

     5.3  Bill to Phone Transaction Limits. Content Provider acknowledges that
ATTWS may in its discretion from time-to-time impose purchase limits for Bill to
Phone Transactions and ATTWS may reject Bill to Phone Transactions (i) to the
extent such transactions bring the total value of a User's Bill to Phone
Transactions in any calendar month to more than the purchase limit per month
($50 at the present time), or (ii) if the User is delinquent in paying his/her
ATTWS bills or otherwise has not maintained the User's account in good standing.
At its discretion and subject to the User's agreement, ATTWS may redirect
rejected Bill to Phone Transactions to Bill to Card Transactions.

     5.4 ATTWS Service Fee and Payment Terms; Bad Debt Risk. Content Provider
will owe ATTWS a service fee ("Service Fee") for Bill to Phone Transactions
during any month equal to: i) [*] per transaction for transactions under [*] and
ii)

[*] of the Retail Purchase Price of Digital Content for transactions of [*] or
more. For these purposes "Retail Purchase Price" means the gross price charged
to the User, excluding any applicable taxes, surcharges or other governmental
fees or assessments. Content Provider will bear the risk of Bill to Phone
Transaction payments that are not collected from a User ("bad debt"). In that
regard, Content Provider authorizes ATTWS to withhold the current bad debt fee
of [*] of the Retail Purchase Price of Digital Content purchased in Bill to
Phone Transactions during any month to cover bad debt ("Bad Debt Withholding").
At its discretion, ATTWS may, upon notice to Content Provider (i) adjust the
amount of the future Bad Debt Withholding to reflect actual experience with Bill
to Phone Transaction bad debt, and (ii) charge back or refund, as the case may
be, Content Provider for actual bad debt in excess of or under the amount
withheld. ATTWS will have the right, in accordance with its business systems and
procedures, to allocate partial User payments for a "look-back period" between
Bill to Phone Transactions and other charges payable by the User to ATTWS for
purposes of calculating actual bad debt and ATTWS shall be paid first for all
User partial payments. For purposes hereof, the "look-back period" will be a
180-day period commencing on the date that the subject account is written off
(or such other review period as ATTWS adopts). Payments for Bill to Phone
Transactions will be made by ATTWS through the Payment Processor to Content
Provider, net of applicable Service Fees, Bad Debt Withholding and other
chargebacks, offsets, credits, refunds and, if applicable, taxes. Although
payments will be made on a monthly basis, such payments generally will trail
sixty to ninety days after the date of the subject Bill to Phone Transaction.
Content Provider hereby authorizes ATTWS to offset against funds held by ATTWS
and owed to Content Provider, to recover any chargebacks, credits, refunds or
reversals for a given period. Notwithstanding any chargeback, credit, refund or
reversal for a Bill to Phone Transaction, ATTWS will be entitled to retain the
Service Fee and, subject to any subsequent adjustments based on actual bad debt
experience, the Bad Debt Withholding with respect to such transaction.

     6.   Taxes.

     On behalf of Content Provider, ATTWS will report and remit to the
applicable governmental entities any sales/use or similar end-user taxes or fees
which may be assessed in respect of Content Provider's sale of Digital Content
for Bill to Card Transactions or Bill to Phone Transactions. The jurisdictions
for which such taxes should be charged and the categorization of products for
the purpose of calculating taxes will be determined by ATTWS by reference to its
own internal processes for ATTWS' digital content. Content Provider will be
responsible for all other taxes, charges and governmental fees with respect to
the sale of Digital Content that may apply, including all taxes based on the net
income, franchise, property and/or net worth of Content Provider.

     7.   Responsibility for Digital Content

As between ATTWS and Content Provider, all risks and liabilities for the
purchase of the Digital Content by the User through the e-Wallet, including but
not limited to the risks of non-payment and fraud, are the responsibility of
Content Provider. If the proceeds from a purchase have been collected by ATTWS
and remitted to Content Provider, and such proceeds are later subject to a
chargeback, credit or refund, then ATTWS will charge the appropriate amounts
back to Content Provider by either offsetting such chargeback, credit or refund
against any other amounts owed by Content Provider to ATTWS or invoicing Content
Provider for such amounts.

     8.   Customer Care

     8.1  Billing Disputes. As between the parties, ATTWS will have sole
responsibility for settling any billing disputes with Users regarding the
purchase of Digital Content through the e-Wallet. If ATTWS, in its sole
discretion, determines that a full or partial refund should be granted to a
User, ATTWS may grant such refund. If such refund takes place after Content
Provider has received payment for the subject transaction, Content Provider will
pay its portion of the refunded amount to ATTWS and ATTWS may offset such
amounts against any other amounts owed by ATTWS to Content Provider or ATTWS may
invoice Content Provider for such amount. If such refund takes place before
Content Provider has received payment for the transaction concerned, Content
Provider will not receive payments for such transaction and Content Provider's
account with ATTWS will be adjusted accordingly.

     8.2  Customer Support. Content Provider will provide first-tier customer
care for Users with respect to the use and functionality of Content Provider's
Digital Content. In that regard, Content Provider will provide a hyperlink or
email address to its customer care support center for integration into the
e-Wallet digital receipt on the ATTWS Personal Web Site and on the Content
Provider Mobile Channel. ATTWS will provide first-tier customer care for Users
with respect to the billing of Digital Content purchased via the e-Wallet.

internal purposes in order to optimize mobile commerce within the ATTWS Wireless
Data Service, including but not limited to compilation of Transaction Data for
the presentation of a digital receipt to the User and maintaining a User profile
for the delivery of services and information to the User. ATTWS may distribute
the Transaction Data to Qpass or other vendors or agents to assist ATTWS in its
permitted use of the Transaction Data, provided that such vendors or agents are
under confidentiality obligations at least as restrictive as ATTWS with respect
to the Transaction Data. Moreover, ATTWS may disclose Transaction Data to the
extent it is required to do so by law. ATTWS and its vendor may provide
aggregate reports to third parties containing Transaction Data provided that
such reports do not disclose any personally identifiable information about
Content Provider or any User.

     10.  Indemnification.

In addition to its indemnification obligations under the Agreement, Content
Provider agrees to indemnify, defend and hold ATTWS and its directors, officers,
employees and suppliers harmless from and against any claims arising from or
relating to Content Provider's provision, promotion, advertising or delivery of
the Digital Content. Further, each party will indemnify the other for claims
arising from or relating to a violation of law by the indemnifying party.

     11.  Warranties.

     11.1 Representation and Warranty. ATTWS represents and warrants to Content
Provider that it has the full power and authority to enter into this Addendum
and to make the e-Wallet, Bill to Phone and Bill to Card services available as

                              Integration Services

Integrating Content Provider Digital Content under the e-Wallet involves
configuring associated settings in the e-Wallet systems and Digital Content.
Activation Services performed by ATTWS and/or Qpass:
     .  Configure the Content Provider Digital Content for access to the Content
        Partner Assistance Center ("CPAC", the online activity reporting and
        support site for Content Provider partners).
     .  Configure end-user support system settings for the Content Provider's
        offerings (policies for escalating support incidents, contact names for
        service downtimes, etc.),
     .  Setup up of up to ten discrete priced products based on template forms.
     .  Provide the Content Provider with the most current system documentation
        and step-by-step service set-up guide.

ATTWS and/or Qpass will manage the integration process, as follows:

Within 3 business days of receiving notification and Content Provider contact
information from ATTWS, will send the Content Provider the current system
documentation and step by step service setup guide.

Within 3 business days of receiving the completed Digital Content activation
worksheet from the Content Provider, will configure the Digital Content for
access to the CPAC, generalized support policies, and other settings to affect
the startup of the Content Provider's account within the e-Wallet systems.

Within 3 business days of receiving the completed Content Provider's Digital
Content offering configuration worksheet, will attempt to configure the new
Content Provider offering in the e-Wallet systems and either 1) notify the
Content Provider that the offering has been successfully configured and is ready
for testing, or 2) notify the Content Provider of what modifications to the
worksheet are necessary in order for a functional product to be configured.

Certification Services

Before a new Digital Content offering is placed into a production environment,
Content Provider will request an e-Wallet certification. A new offering will
pass certification if the purchase process and subsequent access period control
works from end to end in accordance with expected product behavior (see
documentation).

If a Content Provider offering does not pass certification, will provide a
written report detailing why it did not pass and what actions the Content
Provider can take to make the offering certifiable. If a Content Provider
offering does not achieve certification on its second submission, the Content
Provider must contract with Qpass for professional service assistance at the
then-prevailing rates.

Upon receipt of Content Provider's request for each product certification, will
within 2 business days either certify the product and move it into a production
environment, or issue a report to Content Provider detailing why it did not pass
and what actions the Content Provider can take to make the offering certifiable.

                      e-Wallet Service for Digital Content

The e-Wallet for Digital Content contains two forms of payment mechanisms for

The e-Wallet for Digital Content manages the entire transaction process,
including:

..  Account provisioning - simplifies consumer registration and account set-up at
   any time when signing up for wireless service, on a wired or wireless portal,
   or at the point of purchase.

..  Authentication - determines whether a consumer is authorized to make certain
   purchases or access a product through a combination of username and the most
   appropriate form of authentication (password, PIN, voice print, or phone
   number) determined by the device or carrier. The e-Wallet authenticates
   transactions at the payment-method level, to detect whether users have the
   appropriate credentials attached to their accounts and to ensure that the
   payment method (including credit and debit cards, stored-value and draw-down
   accounts, direct carrier billing, and prepaid accounts) is valid and
   sufficiently funded.

..  Transaction Management - extends carriers' billing and customer management
   systems to ensure that transactions occur seamlessly and that payment is
   distributed to all parties in the transaction. The e-Wallet supports and
   manages the entire financial transaction and payment process, including
   spending-limit enforcement, real-time authorization, rating of purchase
   requests against business rules, transaction processing and capture, purchase
   aggregation, collection of funds, remittance, and distribution of revenue to
   multiple parties.

..  Product Management - product management tools allow Content Providers to
   create, distribute, and promote the sale of Digital Content. The e-Wallet
   supports a wide range of business models, packages, and price points,
   allowing Content Providers to create and sell a variety of different
   products.

..  Reporting - Through a password-protected online site, the Content Partner
   Assistance Center (CPAC), the e-Wallet provides Content Providers with
   comprehensive consumer and sales data in two formats: Preformatted HTML
   reports and downloadable raw transaction data, in zipped ASCII format.

..  Customer Support - The e-Wallet Online Assistance Center provides
   self-service account management functions for Users. The Customer Care Center
   provides Users and Content Providers with direct access to purchase
   information as well as tools and support to maintain tier-one service, such
   as conduct refunds and update account information.

ATTWS, either directly or through Qpass, will provide Content Provider with the
User Documentation, including the Digital Content Quickstart Guide. The parties
agree that the User Documentation is provided for information purposes only to
assist Content Provider with its integration with the e-Wallet. Neither ATTWS
nor Qpass makes any representations or warranties in or concerning the User
Documentation.
