3. SOFTWARE AND SERVICES DEVELOPMENT AND TESTING

3.1 Basic Services. At Danger's sole cost and expense, Danger will develop and provide the Basic Services, which will include those functions set forth in Exhibit A, and those Basic Services added pursuant to this Agreement. Any deletion or addition to the Basic Services shall require the mutual written consent of the parties. Danger will, in accordance with Section 7.6, support and maintain the Basic Services for all Danger Devices; provided however, that Basic Services may not be "backwards compatible" with Danger Devices launched before such Basic Services were available. The parties shall use the Roadmap process, described in Section 3.4 below, to mutually agree on which Basic Services will be supported for different Danger Device models. Danger will continue to support the Basic Services for all future Danger Devices, as provided for herein.

3.2 Upgrades and Enhancements. At Danger's sole cost and expense, Danger will make reasonable commercial efforts to continue to develop and enhance the Danger Software and the Danger Services. Danger will make available to T-Mobile a minimum of one (1) Minor Release of the Danger Software each year in accordance with the development and launch schedule presented in the Roadmap (defined below). Danger will also make available to T-Mobile in 2006 at least one (1) Major Release of the Danger Software.

Execution Copy

T-Mobile and Danger Confidential

competitive to T-Mobile or its affiliates. The software on Danger Devices purchased by T-Mobile will be "white-labeled" and will not contain any Danger Marks or other marks without T-Mobile approval. Notwithstanding the foregoing, the boot up screen for the Danger Software on the "Sidekick III" and "Sidekick Style" Danger Devices will contain Danger "ingredient" branding (e.g. "Powered by Danger") as designated by T-Mobile. The parties shall discuss Danger ingredient branding for boot up screens for the Danger Software on other Danger Devices, but have not yet agreed on this matter. Danger may include an "about" page, or similar page, which will contain only the trademarks, service marks, and copyright notices about Danger and its licensors. Such page will be subject to T-Mobile's prior written approval.

3.4 Roadmap.

(a) On a rolling [ * ] basis, delivered every quarter during the Term, Danger will provide for T-Mobile's approval, a roadmap for new features, upgrades, and evolution of the Danger Service and Danger Devices (the "Roadmap"). The Roadmap will be presented in two parts: (1) "Hardware Platform," which shall outline Danger Devices models and the Device Software and Danger Service development for such models and (2) "Services and Features," which shall outline the development of Danger Service and Device Software features that are independent of hardware platform development. The Roadmap will detail features and upgrades that Danger is committed to deliver to T-Mobile. The Roadmap will also detail features and upgrades that Danger is planning to provide, but for which schedules and specifications are not yet finalized. The Roadmap will also detail features that Danger is investigating, but which are only at a concept stage. If Danger requests NRE for development of a feature, then T-Mobile shall be entitled to a [ * ] for such feature. Any such feature and associated [ * ] shall be discussed by the parties in the Roadmap process and must be mutually agreed upon in writing by the parties. In addition, if there are known third party royalties associated with particular features, the parties shall disclose such costs, discuss, and mutually agree which party shall bear such royalties prior to agreeing to add such features to the Roadmap. Such roadmap will [ * ] vis-�-vis other wireless network operators. The Roadmap as of the Effective Date is attached hereto as Exhibit E.

(b) Upon agreement by T-Mobile of the Roadmap, and unless otherwise agreed upon by the parties in writing, new features on the agreed upon Roadmaps will be made available to T-Mobile as part of the Monthly Service Fee (as defined below), and Danger will not charge any additional fees unless expressly agreed upon in writing by T-Mobile.

(c) For Roadmap items that T-Mobile wishes to expedite, or for features T-Mobile would like developed that are not on the Roadmap, the parties may mutually agree to have Danger perform special development projects. Amounts charged to T-Mobile for such additional development shall be at [ * ].

(d) Once per quarter, appropriate executives from Danger and T-Mobile shall discuss the Roadmap, agree upon the commitments in the Roadmap and review the parties' progress in developing and deploying new features for the Danger Service and the Danger Software (the �Quarterly Roadmap Meeting�). The parties currently plan that such discussions shall include Danger's Chief Executive Officer, Henry R. Nothhaft, and T-Mobile's Sr. Vice President and Chief Development Officer, Cole Brodman, as well as appropriate representatives from Danger's product management group, T-Mobile's product realization group and the parties' respective engineering organizations. The timing for such discussions shall be mutually agreed upon by the parties.

(e) Once per quarter, at least thirty (30) days prior to the Quarterly Roadmap Meeting, T-Mobile will provide Danger with a ranked list of a reasonable number of Software and

Execution Copy

T-Mobile and Danger Confidential

Features Roadmap items that are T-Mobile's highest priorities (each a "T-Mobile Priority Item"). At the Quarterly Roadmap Meeting, the parties shall mutually agree to a realistic "Target Date" for delivery of a release candidate of such T-Mobile Priority Item to T-Mobile for testing. Upon such agreement, the T-Mobile Priority Item shall be deemed "committed" on the Roadmap. At the time the Target Date is set for each T-Mobile Priority Item, the parties shall also mutually agree to an "Early Date" and associated "Early Bonus," and a "Late Date" and associated "Late Fee." The Early Bonus and the Late Fee will be the same amount. If Danger delivers the release candidate for a T-Mobile Priority Item on or before the applicable Early Date, and that release candidate is Accepted by T-Mobile after testing without making substantive exceptions to the specification for the Services or the T-Mobile testing process, then T-Mobile shall pay Danger the Early Bonus within thirty (30) days of the Acceptance of the T-Mobile Priority Item. If Danger delivers the release candidate for a T-Mobile Priority Item after the Late Date, Danger shall pay T-Mobile the Late Fee within thirty (30) days of the Late Date. All schedules and mutually agreed upon Roadmap dates will be equitably adjusted for material delays caused by T-Mobile. In addition, at the time a T-Mobile Priority Item is committed on the Roadmap, the parties shall mutually agree on schedule-impacting, development dependencies for which third parties are responsible (each a "3^rd Party Dependency"). If, through no fault of Danger, material delays result from 3^rd Party Dependencies, the parties shall adjust the Roadmap schedules appropriately. Delays that may result from third parties that are not listed as a 3^rd Party Dependency are the responsibility of Danger and will not result in adjustments to the Roadmap schedules.

(f) Custom Development of Roadmap Items. During the period from [ * ] to [ * ] T-Mobile agrees to spend up to [ * ] dollars ($[ * ]) (the "Development Fund") for the purpose of supplementing the non-recurring engineering ("NRE") funding for development of T-Mobile-specific features or applications, or for the acceleration of Roadmap items. Danger will increase its development resources in order to complete projects funded by the Development Fund. At the Quarterly Roadmap Meetings, the parties shall discuss which Roadmap items will be funded with Development Funds, the amount of NRE payments and the scope and schedule for each such item. In T-Mobile's discretion, T-Mobile will identify which projects, and the schedule priority for such projects, that will be funded by the Development Fund. The parties shall mutually agree in writing to statements of work (SOW) that detail the specifications and schedule for each Roadmap item covered by this Section 3.4(f). All development work to be funded by the Development Fund will be at costs verifiable by T-Mobile. If Danger fails to deliver an acceptable release candidate of the Roadmap item by the scheduled date for that item, then T-Mobile will be responsible for [ * ] for that project, and if Danger fails to deliver an acceptable release candidate within sixty (60) days of the scheduled delivery date for that item (or such other mutually agreed upon time period), then T-Mobile will not be responsible for [ * ] for that project. Schedules in any SOW shall be equitably extended for delays attributable to T-Mobile. In each SOW, the parties shall also agree to [ * ] for the Roadmap item paid for with Development Funds.

3.5 Danger Premium Services. Danger will identify in the Roadmap Danger Services for which it desire to charge additional service fees. Upon mutual agreement by each party, any new Danger Services for which T-Mobile agrees to pay an additional service fee will be a Danger Premium Service.

3.6 Testing Procedures and Acceptance Process for Danger Software. This Section 3.6 applies to the testing and acceptance of all Danger Software, and all Upgrades or Enhancements to the Danger Software, except for Danger Premium Content, which is subject to the testing and approval process set forth in Exhibit D.

(a) At Danger's cost and expense and prior to delivery to T-Mobile for testing, Danger (or the Manufacturer) will test each new Danger Software Upgrade or Enhancement to ensure that

(d) Prior to introducing any Danger Software Upgrades or Enhancements, Danger will work with T-Mobile to develop a "target acceptance plan", according to the prevailing test methodology used by T-Mobile at the time of the release. This will include the release of multiple Alpha (as applicable) and Beta versions of the software for early review by T-Mobile, and subsequently a "Release Candidate" release, which will pass through several iterations of testing, according to the T-Mobile methodology. T-Mobile testing process and minimal entrance criteria are documented in T-Mobile US PRD 30-38 "Test Requirements for Terminal Suppliers."

(e) Feedback Regarding Prototypes of Danger Software. T-Mobile shall use commercially reasonable efforts to provide Danger with written comments as promptly as practicable regarding T-Mobile's testing of the Danger Software as set forth in Section (c) above.

(f) Final Approval and Acceptance of Danger Software. After Danger's delivery of a Release Candidate of the Danger Software, T-Mobile will use commercially reasonable efforts to promptly provide in writing either (i) an acceptance letter stating that T-Mobile has accepted the Danger Software for delivery to its Subscribers ("Acceptance", "Accept" or "Accepted"), or (ii) a rejection letter that describes in reasonable detail why T-Mobile has not Accepted the Software. If T-Mobile has not issued an Acceptance letter for the Danger Software within sixty (60) days after Danger's delivery of a Release Candidate of the Danger Software, or thirty (30) days after any fixes or upgrades have been applied to such final Release Candidate of the Danger Software, whichever date is later, and so long as any delay in Acceptance is not due to outstanding Danger Software issues of which T-Mobile has notified Danger in writing, then T-Mobile's exclusivity set forth in Section 9.3 may be forfeited for that Danger Software at Danger's discretion. If T-Mobile does not Accept a Danger Software Upgrade or Enhancement, the parties will use commercially reasonable efforts to resolve outstanding issues, unless T-Mobile does not wish to provide such Danger Software Upgrade or Enhancement.

Throughout the Term, T-Mobile will provide to Danger monthly reports of new Subscriber activations, deactivations, cumulative Active Subscribers, and other data as reasonably requested by Danger and agreed upon by T-Mobile. All such data will be T-Mobile's Confidential Information and Danger will treat such data as confidential pursuant to its confidentiality obligations in this Agreement, provided that Danger may use such data for purposes of financial reporting. T-Mobile shall provide to Danger written notice of (i) on a periodic basis, reports on the trends reported in bugs and defects of the Danger Devices or Danger Services, (ii) any legal action or threatened legal action involving the Danger Device or Danger Service, provided that such notice does not adversely affect T-Mobile in regard to any rights to indemnification, and (iii) T-Mobile's breach, or threatened breach of any third party agreement to provide synchronization or instant messaging services if such breach or threatened breach will adversely affect Danger's provision of Danger Software or Danger Services.

5. Premium Content and Instant Messaging.

5.1 Premium Content. The Premium Download Manager is the primary means by which to deliver Premium Content to Subscribers. Danger will host and maintain the Premium Download Manager as part of the Basic Services. The terms by which the parties shall offer Premium Content are set forth in Exhibit D.

5.2 Instant Messaging. T-Mobile may offer third-party instant messaging functionality via the Danger Service (e.g. AIM, Yahoo! Messenger) (each an "IM Service"). Danger shall be responsible for developing and maintaining the Danger Software and the Danger Service to support IM Services that the parties mutually agree to launch and support. As of the Effective Date, the parties have agreed to support AIM and Yahoo! Messenger. Additional IM Services may be offered via the Danger Service by mutual written agreement of the parties. T-Mobile shall be responsible for paying any license or other fees to the third-party IM Service providers related to the use of an IM Service so T-Mobile may provide the IM Services to Subscribers via Danger Services. Such fees shall be paid directly to the third-party IM Service providers at the rates negotiated by T-Mobile. For any IM Service that the parties mutually agree to offer via the Danger Service, Danger shall be responsible for paying any technology license fees, if any, to a third party IM Service provider. The continued offering of IM Services is conditioned upon each party having sufficient rights to offer each particular IM Service via the Danger Service and the Danger Device to Subscribers.

6. Prepaid Danger Service. The parties previously launched the Danger Service enabled for Prepaid Subscribers pursuant to the Service Specifications set forth in "Prepaid Services PRD" dated October 1, 2004 (the "PRD"). Any changes to the PRD shall require the mutual written agreement of the parties.

6.1 Ongoing Operations. Each party shall continue to maintain its technical systems in good working order to ensure the proper functioning and billing for the Danger Service for Prepaid Subscribers. In addition, each party shall use reasonable commercial efforts to provide a pre-production test environment so that they may test the impact of modifications and new releases of the Danger Service on Prepaid Subscribers. T-Mobile has provided Danger (at no charge) with 50 SIM cards provisioned for the Prepaid Danger Services solely for the testing and development of the Prepaid Danger Service for T-Mobile. Danger may only provide the SIM cards to Danger employees tasked with developing or testing the Prepaid Danger Service. Upon request, Danger will provide to T-Mobile the names of any Danger

11.

Execution Copy

T-Mobile and Danger Confidential

employees that are using such SIM cards, and T-Mobile may require that such employees sign an agreement stating that such employee will only use the SIM card for the purpose of testing and development of the Prepaid Danger Service. If an employee leaves Danger, or if the employee is no longer involved with the development or testing of Prepaid Danger Services, then Danger will ensure that the employee no longer uses the SIM card and will notify T-Mobile if that SIM card has been provided to a different Danger employee. T-Mobile may request that SIM cards be returned to T-Mobile at any time with thirty (30) days written notice to Danger; provided however, in the event of such request, Danger shall not be responsible for any development or testing delays caused as a result and Danger may require T-Mobile to reimburse Danger for a mutually agreed upon number of replacement SIM cards needed for development and testing purposes. Danger will provide T-Mobile the following documentation for customer care support for the Prepaid Service: Danger Support Tool documentation and screen shots, frequently asked questions and training documentation.

6.2 Future Software and Prepaid Danger Services. Danger shall maintain the Danger Software so that Manufacturers may offer future Danger Device models that support Prepaid Subscribers. Danger will include support for Prepaid Subscribers in all new Danger Services, including all Upgrades and Enhancements. Danger will include in Prepaid Danger Services all Basic Services. However, if Danger requests NRE for development of the feature for the Prepaid Service, then the parties shall discuss Prepaid Danger Service support (and any NRE) for such feature in the Roadmap process, as set forth in Section 4.s

6.3 Service Level Agreement. The Prepaid Danger Service will comply with the Service Level Agreement and requirements set forth in Section 4.1(b) of the Agreement. Danger will use commercially reasonable efforts to have all provisioning requests sent by T-Mobile to Danger via the XML data exchanges responded to by Danger within one (1) second.

6.4 Premium Content for Prepaid Subscribers. Prior to Danger fulfilling a Prepaid Subscriber's request to purchase Premium Content, Danger shall query the Prepaid Account via the interface mutually agreed upon by the parties to debit the Prepaid Account for the purchase amount of the Premium Content. If T-Mobile's billing system confirms that the purchase amount was debited (i.e. sufficient funds existed in the Prepaid Account), Danger will fulfill the download request via the Premium Download Manager and will bill T-Mobile for a successful download. Danger will only bill T-Mobile for Successful Downloads of Premium Content in which Danger debits the Prepaid Account of the Prepaid Subscriber. A "Successful Download" is the occurrence of the successful delivery of a piece of Content to a Subscriber's Danger Device. Danger will not bill T-Mobile (or will credit T-Mobile) for any unsuccessful downloads to Prepaid Subscribers. If T-Mobile's billing system replies that insufficient funds exist in the Prepaid Account, Danger will not fulfill the download request and T-Mobile will not be billed. Danger will invoice T-Mobile for purchases of Premium Content by Prepaid Subscribers in the same manner as currently set forth in the Agreement. Prepaid Subscriber purchases of Premium Content during the first 24 hours of such Subscriber's activation will be billed to T-Mobile irrespective of the fact that no Prepaid Danger Service Fee is due during the first 24-hour period following activation. Danger shall provide Premium Content reporting broken out between post-paid and Prepaid Subscribers in its invoices to T-Mobile.

6.5 Prepaid Subscriber Support. Support for Danger Services to Prepaid Subscribers shall be the same as that provided for all Subscribers per the terms of Section 4.2.

6.6 Prepaid Subscriber Billing and Reporting. A Prepaid Subscriber will be considered an Active Subscriber when he/she has sufficient credit in his/her account such that T-Mobile successfully debits that Prepaid Subscriber's account for T-Mobile's 24-hour data service fee. A successful debit to the Prepaid

12.

Execution Copy

T-Mobile and Danger Confidential

Subscriber is determined by a confirmation from the T-Mobile Converged Charging Node (CCN) to Danger that the Prepaid Subscriber's account has sufficient funds and has been charged for a 24-hour data service fee. Notwithstanding the above, for the first 24 hours in which a Prepaid Subscriber activates his/her Prepaid Danger Device, the Prepaid Subscriber will not be considered an Active Subscriber.

6.7 Prepaid Subscriber Reporting. Within ten (10) business days of the end of each month, T-Mobile will provide to Danger a report of that month's total for Service Fees for Prepaid Subscribers. Such report shall include, at a minimum, the aggregate amount of Service Fees due and the following items by Subscriber: IMSI, MSISDN, and number of billable days (the "Prepaid Billing Report"). T-Mobile will pay Danger for such fees in accordance with Section 10. Danger shall only reimburse or credit T-Mobile for credits issued by T-Mobile for Service Fees for Prepaid Subscribers where such credits were issued as a result of overcharges or other errors caused by Danger that occur within the Prepaid Danger Service. Invoices for Service Fees regarding Active Prepaid Subscribers will be based upon the reports created by T-Mobile.

6.8 Prepaid Subscriber Deactivation. If a Prepaid Subscriber has not added funds to his/her Prepaid Account for a period of ninety (90) days after he/she has been denied access to the Danger Service for insufficient funds, T-Mobile shall send Danger a deactivation request. Danger shall continue to store such Prepaid Subscriber's data for a period of sixty (60) days following T-Mobile's deactivation request, after which Danger may deactivate the Prepaid Subscriber's Danger Service account and delete all data for such account. Each month Danger will provide T-Mobile a list of Prepaid Subscriber accounts which have been at insufficient funds and/or suspended for at least 150 days. T-Mobile will use commercially reasonable efforts to review the list and respond to provide a list of the Prepaid Subscribers who may be deactivated.

7. DANGER DEVICES

7.1 Licenses. Danger will enter into license agreements with Manufacturers, whereby Danger will license to the Manufacturer rights necessary to manufacture and distribute the Danger Software on Danger Devices and provide reasonable technical assistance to Manufacturers.

7.2 Development and Testing. Danger will use reasonable efforts to support Manufacturers' development of Danger Devices in accordance with specifications agreed upon in writing among Danger, Manufacturer and T-Mobile. Unless otherwise agreed to by the parties, Danger shall not be obligated to provide Danger Devices to T-Mobile for testing; rather T-Mobile shall obtain test devices from Manufacturers. T-Mobile shall use commercially reasonable efforts to require the Manufacturer to obtain any necessary agency, regulatory, and industry-required approvals for Danger Devices, including FCC, PTCRB, and other governmental or industry-required approvals. Pursuant to its agreements with Manufacturers, Danger agrees to provide assistance reasonably requested by Manufacturers for the Manufacturer to obtain such approvals.

7.3 Purchase Terms. If T-Mobile desires to purchase Danger Devices, T-Mobile shall purchase Danger Devices directly from Manufacturers. All Danger Device purchase terms, including without limitation, pricing, lead times, order fulfillment, and warranty servicing and post sales support shall be determined between T-Mobile and the Manufacturer.

7.4 Branding. The hardware for each Danger Device will be branded as agreed upon between T-Mobile and Manufacturer.

7.5 Forecasts. At the beginning of every month, T-Mobile will provide Danger with a non-binding, rolling forecast of its projections for the acquisition of Subscribers during the next six (6) months. Such forecasts do not create a commitment for T-Mobile to purchase the Danger Devices or to acquire Subscribers in any manner in the time period specified in such forecast.

7.6 Device Software and Service Support and Maintenance. Danger shall provide maintenance Upgrades or Enhancements for Danger Devices for [ * ] (the "Support Period"). Danger shall also support and maintain the Danger Services for each particular Danger Device model for the duration of the Support Period. Danger shall make new features and functions available for Danger Devices via Upgrades and Enhancements only for a period of [ * ].

8. SALES AND MARKETING

T-Mobile will use reasonable efforts to distribute and market Danger Devices and Danger Services within T-Mobile's wireless service footprint in the continental United States. T-Mobile at all times may decide, in its sole discretion, how the Danger Devices and Danger Services are to be marketed, sold, offered, and distributed under this Agreement. T-Mobile makes no representations or guarantees regarding maximum sales, projected revenues, or expected profits in relation to the Danger Device or Danger Services.

10. PAYMENTS/RECORD KEEPING

10.1 Danger Monthly Service Fees.

(a) Service Fees. T-Mobile shall pay Danger a per-Subscriber fee for each Active Subscriber (including Prepaid Subscribers) as set forth in the table below (the "Service Fee"). Service Fees shall be calculated on a pro rata daily rate, as described in Section (b) below. Unless otherwise agreed upon in writing by the parties and except for Premium Services, Danger will not charge T-Mobile any other fees for providing the Basic Service or for customizations or enhancements thereto. The

15.

T-Mobile and Danger Confidential

Service Fees stated below will be applied on a "graduated" tax-table basis. For the purpose of clarity, the Service Fees payable by T-Mobile for the first [ * ] Subscribers will remain constant at [ * ] per Subscriber per month, while Services Fees for the next tier [ * ]+) will be paid at [ * ] per month, and so forth.


Subscribers		Monthly Service Fee
*[ ]**		*[ ]**
*[ ]**		*[ ]**
*[ ]**		*[ ]**

(b) Service Fee Calculation.

(i) "Post Paid" Subscribers. The Service Fees due for "post-paid" Subscribers shall be calculated based upon the following formula: T-Mobile will pay to Danger One-Thirtieth (1/30th) of the Service Fee for each calendar day that the Active Subscriber is active during the month. For example, the per calendar day Service Fee for the first [ * ] Subscribers will be One-Thirtieth (1/30) of [ * ] or [ * ] per day. If a Subscriber becomes an Active Subscriber on the tenth (10^th) of December, the Subscriber will be an Active Subscriber for twenty two (22) days in the month of December and T-Mobile shall owe Danger [ * ] for such Subscriber (22 X [ * ]). Invoices for Service Fees regarding Active Subscribers will be based upon the reports created by T-Mobile.

(ii) Prepaid Subscribers. The Service Fees due for Prepaid Subscribers will be calculated by the following formula: T-Mobile will pay to Danger One Thirtieth (1/30th) of the Service Fee for each 24-hour period for which a Prepaid Subscriber was an Active Subscriber during the calendar month. Section 6 describes when a Prepaid Subscriber is deemed an Active Subscriber and how billing and reporting for Prepaid Subscribers will be administered. For example, the per calendar day Service Fee for the first [ * ] Subscribers will be One-Thirtieth (1/30) of [ * ] or [ * ] per day. If a Prepaid Subscriber is an Active Subscriber for twenty-two (22) 24-hour periods in the month of December, T-Mobile shall owe Danger [ * ] for such Subscriber (22 X [ * ]. Invoices for Service Fees regarding Active Subscribers will be based upon the reports created by T-Mobile.

(c) Effective Date. The Service Fees stated above will be retroactive to June 1, 2005. Each party agrees that T-Mobile has paid to Danger amounts equal to the retroactive fees for the time period from June 1, 2005 through December 31, 2005. Upon execution of this Agreement, Danger shall invoice T-Mobile for the Services Fees due for any period for which T-Mobile has not paid the fees as calculable under this Agreement for the period from June 1, 2005 to the execution date of this Agreement, less amounts invoiced to T-Mobile for the Basic Services during such period (as adjusted by mutual agreement).

(d) Premium Services. Except for Premium Content, fees for Premium Services will be as mutually agreed upon by T-Mobile and Danger. Fees for Premium Content and reporting and billing administration for Premium Content are set forth in Exhibit D.

10.2 Churn Bonus.

16.

Execution Copy

T-Mobile and Danger Confidential

(a) Terms. In addition to the Service Fee set forth in Section 10.1, for each month during the term of the Agreement in which the blended churn rate for all post-paid Subscribers (across all Danger Devices) is equal to or less than the blended churn rate reported quarterly by T-Mobile for its general subscriber base (the "Churn Threshold") plus [ * ] basis points, T-Mobile will pay Danger an additional [ * ] [ * ] per Active Subscriber (both post-paid and Prepaid Subscribers) per month. For purposes of this calculation, a "basis point" is equal to one hundredth of a percent. For each month during the term of the Agreement in which the blended churn rate for all post-paid Subscribers (across all Danger Devices) is less than or equal to the Churn Threshold minus [ * ] basis points, T-Mobile will pay Danger an additional [ * ] [ * ] per Active Subscriber (both post-paid and Prepaid Subscribers) per month, for a total potential bonus of [ * ] [ * ] per Active Subscriber per month. T-Mobile will calculate the Churn Threshold and the blended churn rate for all post-paid Subscribers, and report such calculations to Danger on a quarterly basis within thirty (30) days of the end of the calendar quarter. Bonus amounts due will be calculated applying the methodology described in Section 10.1(b). If any bonus applies, Danger will invoice T-Mobile in accordance with the parties' invoicing and payment procedures set forth below. Blended churn is churn calculated across the base of applicable post-paid Subscribers, as reported by T-Mobile. The churn figures that will form the basis for the additional payments described herein will be reported by T-Mobile to Danger at the same time T-Mobile and/or its parent company discloses its general churn numbers to the public.

(b) First Six Months. Notwithstanding Section 10.2(a), for the period from June 1, 2005 to December 1, 2005, the Churn Threshold for triggering the additional bonus payments in Section 10.2(a) will be [ * ] of the difference between Danger's blended churn rate for the quarter ended June 30, 2005 and T-Mobile's blended churn rate for the quarter ended June 30, 2005. For example, if the blended churn rate for the quarter ended June 30, 2005 calculated across all post-paid Subscribers is [ * ]% and T-Mobile's reported blended churn rate for the quarter ended June 30, 2005 is [ * ]%, the Churn Threshold will be [ * ]%. If the July 2005 blended churn rate for post-paid Subscribers was equal to or below [ * ]%, Danger would earn an additional [ * ] per Subscriber (both post-paid and Prepaid Subscribers) for July, and if the blended churn rate for post-paid Subscribers was equal to or below [ * ]% Danger would earn an additional [ * ] per Subscriber (both post-paid and Prepaid Subscribers) for July, for a total bonus of [ * ] per Subscriber. Following the execution of this Agreement, T-Mobile shall perform the appropriate calculation and pay Danger any Bonus that is due under this paragraph 10.2(b).

10.3 Subscriber Tracking. Danger will, at its sole cost, collect and report to T-Mobile Subscriber usage and other information requested by T-Mobile. The information to be collected and reported by Danger pursuant to this Section 10.3 and the format of such reports, will be mutually agreed to by the parties.

10.4 Subscriber Billing. T-Mobile, in its sole discretion, shall control and administer the amounts and the process by which Subscribers may be charged such amounts, if any, as T-Mobile establishes in its sole discretion with respect to access to and/or use of the Danger Services. T-Mobile, at its own cost, will be responsible for the billing and collecting of such amounts from Subscribers.

10.5 Post-Paid Billing Reports. Within ten (10) business days after the end of each calendar month during the Term, T-Mobile will deliver to Danger a billing report (collectively the "Post-paid Billing Report") that details the Service Fees due for such calendar month and data for Active Subscribers for such calendar month so that Danger can verify T-Mobile's calculation of the Service Fees due. The Post-paid Billing Report shall include, at a minimum, the aggregate amount of Service Fees due and the following items by Subscriber: IMSI, MSISDN, initial billing date, billing start date for the month, billing end date for the month, number of billable days, amount owed to Danger for that Subscriber.

17.

Execution Copy

T-Mobile and Danger Confidential

10.6 Payment. T-Mobile will pay to Danger the amounts set forth in the Prepaid Billing Report and Post-paid Billing Report (collectively, the "Billing Report") within thirty (30) days of the end of the preceding month. Notwithstanding the foregoing, in the event that T-Mobile does not deliver the Billing Report within twenty (20) business day of the end of the applicable calendar month, Danger shall have the right to invoice T-Mobile for Service Fees dues for such month based on Danger's records and T-Mobile shall pay such invoiced amounts within thirty (30) days. Payments for Premium Content shall be invoiced and paid in accordance with Exhibit D.

10.7 Reconciliation of Fees.

(a) Within ten (10) business days of Danger's receipt of T-Mobile's Billing Report, Danger shall notify T-Mobile if it believes any of the data or payments by T-Mobile are inaccurate and shall provide T-Mobile with a report showing the discrepancies (the "Reconciliation Report"). Such report shall provide the same detail, by Subscriber, as the Billing Report. The parties shall then confer in good faith to determine if T-Mobile's Billing Report failed to include Active Subscribers that should have been billed. If the Billing Report was inaccurate, then any amounts (credits or debits) that are agreed upon shall be applied to T-Mobile's payments for Service Fees for the next calendar month. The parties shall perform a similar reconciliation procedure in the event Danger invoices T-Mobile in accordance with Section 10.6.

(b) On a quarterly basis, T-Mobile and Danger will confer in good faith to determine whether there are users of the Danger Services that are not being counted as Active Subscribers (and are not otherwise accounted for by other authorized use, such as testing and development). If there are unauthorized users, then T-Mobile and Danger will use commercially reasonable efforts to determine how such users are accessing the Danger Service, to prevent such unauthorized access, and will mutually agree on timing for deactivating such users.

(c) At least once per calendar quarter, the parties shall synchronize their records of deactivated Subscribers by sharing deactivation reports. Either party may initiate such process by making a written request (including by e-mail) to the other party.

(d) During the Term and for two (2) years thereafter, T-Mobile shall maintain all Billing Report records and Danger shall have the right to audit such records under the same terms as described in Section 10.8 below.

10.8 Record Keeping and Audit. During the Term and for [ * ] thereafter, Danger shall maintain detailed, accurate records relating to the Danger Services and calculations of the fees payable by T-Mobile pursuant to this Agreement. T-Mobile, at its expense, and upon thirty (30) days advance notice to Danger, shall have the right no more than [ * ] per year during the Term, and for a [ * ] period thereafter, to have an independent accounting firm, reasonably acceptable to Danger (a) examine or audit records and (b) inspect Danger's facilities and procedures in order to verify Danger's compliance with this Agreement (including, without limitation, the figures reported and amounts invoiced by Danger, most favored nation pricing, performance monitoring and Outage information, and verification of increased costs for new services). Any such audit or inspection shall be conducted, to the extent possible, in a manner that does not interfere with the ordinary business operations of Danger. The auditor shall be required to sign a confidentiality agreement prescribed by Danger and shall not be entitled to disclose to T-Mobile any confidential information related to Danger's other customers or partners, [ * ]. If any audit reveals an overpayment of amounts owed or non-compliance with Section [ * ], Danger will credit T-Mobile on a prospective basis against future Service Fees for the amounts overpaid between the date that T-Mobile made the payment and the date of such credit. If T-Mobile is no longer providing Danger

18.

Execution Copy

T-Mobile and Danger Confidential

Services to T-Mobile, then Danger will reimburse T-Mobile for any over payment by T-Mobile. If such overpayment is more than five percent (5%) of the amounts owed by T-Mobile under the period audited, Danger will reimburse T-Mobile the reasonable cost of such audit.

10.9 Taxes. The payments to be made by T-Mobile to Danger do not include sale or use taxes. If Danger is required to pay sales or use taxes based upon the amounts paid by T-Mobile under this Agreement, then such taxes shall be billed to T-Mobile and paid by T-Mobile to Danger and Danger shall (i) remit the same to all applicable taxing authorities as required by law, and (ii) provide to T-Mobile official tax receipts indicating that such taxes have been so remitted. Danger shall reasonably cooperate with T-Mobile to lawfully minimize the imposition of any taxes. To the extent T-Mobile or the transactions contemplated by this Agreement may be exempt from such taxes, Danger will not pay any taxes on behalf of T-Mobile if T-Mobile provides Danger a tax certificate exemption (including, without limitation, a resale certificate). Danger is responsible for and shall pay and hold T-Mobile harmless against all other taxes arising by reason of or in connection with this Agreement, including, but not limited to, taxes based on Danger's income and any employment related taxes applicable to Danger's employees and contractors.

10.10 Legacy Payment Terms. For purposes of clarity, the parties agree that no "Hardware Fees" (as defined in the Original Agreement) shall be due to Danger under this Agreement. Likewise, unless otherwise agreed by the parties, no one time "client license" fees will be due to Danger under this Agreement. The purchase price of any Danger Device will be determined between T-Mobile and the Manufacturer. No "Qualified Return Fees" or "NTF Fees" shall be due to T-Mobile under this Agreement.

11. [ * ]

11.1 Pricing. The prices and fees charged to T-Mobile by Danger for Danger Services hereunder will be under [ * ] terms ("[ * ]"), and such terms will not [ * ] products or services with [ * ] features and functionality. Danger shall provide T-Mobile with [ * ] for all prices, charges, cost, and fees charged to T-Mobile, including, without limitation, service fees for all services and service offerings (including, without limitation, Basic Services, Premium Services (excluding Danger Premium Content)), software, and development costs and resources.

11.2 [ * ] If, during the Term, Danger enters into an agreement or business relationship (including, without limitation, a joint venture or partnership) where a third party (other than a majority owned affiliate of Danger) is given the right (by license, or otherwise), directly or indirectly, to operate and/or host the Danger Service, Danger agrees to promptly [ * ] such third party (including without limitation, [ * ]). If T-Mobile decides, in its sole discretion, to [ * ], Danger will promptly execute all necessary documents and agreements to [ * ]. If T-Mobile decides, in its sole discretion, to continue [ * ], then the [ * ] T-Mobile will be [ * ], taking into account a pro rata allocation of the cost of [ * ] in proportion to the cost for such [ * ].

13.1 Escrow Agreement. The current Master Preferred Escrow Agreement #041205 (the "Escrow Agreement"), dated June 30, 2005 with DSI Escrow Services, Inc. (aka Iron Mountain Incorporated) (the "Escrow Agent"), shall remain in effect during the Term, unless otherwise modified or terminated by mutual agreement of the parties. Danger shall place into escrow the Source Code, object code and related documentation for the Danger Service (the "Escrowed Code").

T-Mobile shall bear the cost of maintaining the software in escrow (to be billed by the Escrow Agent or invoiced by Danger).

13.2 Release of Escrowed Code. In addition to and not in limitation of any other rights or remedies of T-Mobile, the Escrowed Code will be delivered to T-Mobile for use, copying and modification in connection with T-Mobile's separate implementation of the Danger Service (which may include T-Mobile providing the Danger Service to T-Mobile-Related Companies) upon the occurrence of any of the following conditions (each, a "Release Condition"):

(a) [ * ];

(b) Danger ceases to provide the Danger Services for a period of [ * ], except due to a force majeure event under Section 23.6;

(b) The license granted to T-Mobile in Section 13.3(a) will be subject to a fair and reasonable market-value royalty (minus any costs incurred by T-Mobile) as determined by an independent third party appraisal, with the appraiser to be selected by the mutual agreement of the parties. T-Mobile may offset any damages, including lost revenues, due to Danger's breach or nonperformance of this Agreement, against any royalties that may be due pursuant to this Section.

14. Confidentiality, Security, Law Enforcement

14.1 Confidential Information.

(a) The parties acknowledge that each may be given access to certain confidential, proprietary or secret information and material relating to or owned by the other, including but not limited to financial information, pricing information, supplier lists, customer lists, files and other information regarding individual customers, and information regarding that party's business, organization and operations, in the course of the performance under this Agreement. Such information and material shall be the sole and exclusive property of the provider of such information, and each party agrees that during the term of this Agreement and at all times thereafter the receiving party will not disclose such confidential, proprietary or secret information or material, or the terms of this Agreement, to any governmental agency, person, entity, firm or corporation without the explicit prior written consent of the other. This Section shall not apply to any information (a) previously known to either party free of any obligation to keep it confidential; (b) that has been or which becomes publicly known, through no wrongful act of either party; (c) which is rightfully received from a third party who is under no obligation of confidence to either party; or (d) which is independently developed by the receiving party without resort to information that has been disclosed pursuant to this Agreement. This Section shall also not apply to information which is required to be disclosed in order to comply with applicable law or regulation (including, without limitation, SEC compliance) or with any requirement imposed by judicial or administrative process or any governmental or court order, provided however that the party making such disclosure must provide notice to the other party, to the extent possible, at the earliest practicable time prior to such disclosure.

(b) The parties agree that this Agreement is confidential and subject to the provisions set forth in Section 14.1(a) above; provided however that either party may provide copies of this Agreement to its auditors, attorneys, investors and financial advisors that are bound in writing to keep information of this nature confidential.

14.2 Subscriber Data.

(a) T-Mobile will have sole and exclusive ownership of and rights to collect, store, and use all Subscriber Data received by T-Mobile or Danger in the course of any Subscriber's use of the Danger Devices or Danger Services.

(b) Danger may not use, disclose, or provide to any third party (including subsidiaries and affiliates), any Subscriber Data except for the purpose of providing the Danger Services. Notwithstanding the foregoing, Danger may disclose Subscriber Data in response to a court order, subpoena request, or law enforcement investigation. If the FCC or any state or federal government regulatory authority implements rules regarding the use, storage, or dissemination of Subscriber Data, Danger will comply with and implement any procedures required by such rules or regulations. If Danger's compliance with and implementation of procedures required by such rules or regulations result in Danger incurring material additional costs, the parties shall discuss in good faith whether T-Mobile will pay for any such costs. Irrespective of an agreement (if any) between the parties on such costs, Danger

22.

Execution Copy

T-Mobile and Danger Confidential

shall be required to comply with all applicable rules and regulations issued by the FCC or any state or federal regulatory authority regarding the use, storage, or dissemination of Subscriber Data.

(c) Danger may not provide, authorize, or allow any third party (including subsidiaries and affiliates) to provide, any Subscriber Data to any wireless carrier or any non-United States government.

(d) Without limiting the foregoing, Danger will be permitted to use Aggregate Information only for purposes of operating, monitoring, maintaining, developing, and improving the Danger Service and Danger Software. In addition, without T-Mobile's prior consent, Danger may publicly disclose data related to aggregated, world-wide use or performance of the Danger Software and the Danger Service, provided such disclosures could not reasonably be understood or used to state or imply specific numbers about the number of users of Danger services. For example, Danger could announce, without T-Mobile's prior consent, that the Danger Service carried over 1,000,000 instant messages world-wide in a single day. If any proposed disclosure could reasonably be understood to state or imply specific numbers about the number of Danger users, such disclosures may not be made without T-Mobile's prior consent, which consent shall not be unreasonably withheld or delayed. For instance, Danger would be required to obtain T-Mobile's prior consent to announce that Danger completed OTA updates to the 1,000,000 Danger Devices in use in the United States. Notwithstanding the foregoing, in the event that T-Mobile Subscribers represent less than 75% of all Danger users, Danger may make disclosures that state or imply the number of Danger users; provided however, Danger's disclosures shall not state or imply the number of T-Mobile Subscribers.

(e) Department of Justice Agreement. T-Mobile has entered into an agreement with the Federal Bureau of Investigation and the Department of Justice that requires parties contracting with T-Mobile to comply with applicable terms. Danger agrees as follows, provided that (i) if compliance with the following requires Danger to materially change its usual business operations (but not including changes required under other sections of this Agreement), and such changes materially increase Danger's costs to meet the following requirements, then the additional costs to meet such requirements shall be borne by T-Mobile, and (ii) Danger shall provide reasonable notice to T-Mobile of any such additional costs before they are incurred, and all such costs are subject to T-Mobile's prior written approval, which may not be unreasonably withheld:

(i) Danger shall not throughout the term of this Agreement or at any time thereafter store Subscriber audio or data communications occurring in the U.S., or any other Subscriber information, including, without limitation, call transactional data, call associated data, call identifying data, Subscriber information and Subscriber billing records (collectively, "DOJ Subscriber Information") outside of the United States without T-Mobile's prior written consent, which may be withheld for no reason, or any reason, in T-Mobile's sole discretion;

(ii) Danger will provide T-Mobile with at least thirty (30) days prior written notice of its desire to store DOJ Subscriber Information outside the United States, including description of the communications and/or information, identification of the custodian, identification of the proposed location where the communications and/or information would be stored; and identification of the factors it considered in seeking to store the communications and/or information outside the United States;

(iii) Danger will store billing records relating to T-Mobile Subscribers for a minimum period of two years;

23.

Execution Copy

T-Mobile and Danger Confidential

(iv) Danger will store DOJ Subscriber Information in its possession, custody and control if requested by a domestic governmental entity pursuant to 18 U.S.C. � 2703(f);

(v) Danger will store DOJ Subscriber Information in a manner such that the communications and/or information do not become subject to mandatory destruction under any foreign laws;

(vi) Danger will make available to the DOJ in the United States all DOJ Subscriber Information that is stored by Danger or a third party (as permitted under this Agreement);

(vii) Danger will not disclose DOJ Subscriber Information to any foreign government or entity without first (i) satisfying all applicable U.S. federal, state and local legal requirements, including receiving appropriate authorization by a domestic U.S. court, or receiving prior written authorization from the U.S. Department of Justice, and (ii) notifying T-Mobile of the request for such information within five (5) days of its receipt;

(viii) Danger will protect the confidentiality and security of all lawful U.S. process and the confidentiality and security of classified information and sensitive information in accordance with federal and state laws and regulations.

(f) Subscriber Data Protections. Danger will securely protect Subscriber Data, Subscriber passwords and DST access using security procedures, encryption, and firewall protections that have been reasonably agreed upon by T-Mobile and Danger. T-Mobile shall instigate and maintain a similar level of security procedures to control access to Subscriber Data and DST within T-Mobile's operational centers.

14.3 Security.

(a) Documentation. Danger has provided to T-Mobile highly confidential security documentation that comprehensively describes in detail the overall architecture of the Danger Service, including (but not limited to) encryption methodologies (except for security key values), operational practices, entry points to the Danger Service, and connection points between Danger and its operator partners. The Security Information Confidentiality Agreement, dated July 1, 2005, between the parties (the "Security NDA") shall govern T-Mobile's use of and access to any Danger Service security related information, including the documentation described in this Section. Only T-Mobile employees listed in such agreement may view the security documentation.

(b) Regular Security Self Assessment. Danger shall perform regular security self assessments within appropriate time frames, as determined by Danger. Optionally, Danger may contract an external third party to perform the security assessment referred to as audit. Danger shall use reasonable efforts to conduct regular self assessments or audits for all connected systems, applications, and the complete network supporting the Danger Service. Danger will provide to T-Mobile all relevant results of such audits and any action plans that result from an audit or self-assessment.

(c) T-Mobile Security Audit. T-Mobile may conduct a security audit of the Danger System one (1) time per year, or any additional time if T-Mobile documents irregularities with the Danger Service that indicate the operation of the Danger Service may be insecure or if T-Mobile documents a reasonable belief that there may be attacks being made against the Danger System from an external source not accessing the Danger System through the T-Mobile network and system. Any such audit shall be conducted by a third party in accordance with the following procedure: On no less than ten (10) business

24.

Execution Copy

T-Mobile and Danger Confidential

day's notice (except that an audit can occur on an expedited basis if there has been an actual security breach of the Danger Services), an independent third-party auditor reasonably selected by T-Mobile and reasonably acceptable to Danger shall visit Danger's premises during normal business hours to inspect and audit the systems that support the Danger Service. The sole purpose of the audit shall be to determine whether Danger complies with its security documentation and if a security breach has occurred or is likely to occur. As a condition to the audit, the independent third-party auditor and T-Mobile will be required to execute a three-party confidentiality agreement proscribed by Danger. This confidentiality agreement will not permit the third party auditor to forward any information to T-Mobile, except for the final audit report. Such audit will be conducted in a manner that does not unreasonably interfere with the ordinary conduct of the Danger's business or generate unreasonable cost to Danger. Danger and T-Mobile shall each be presented with a report on the results of the audit following its completion. Such report and any other information regarding the audit shall be deemed confidential Danger security information governed by the Security NDA. T-Mobile will bear the costs of such audit. T Mobile is entitled to trigger a security audit no more often than two (2) times per calendar year; provided however, if the assessment or audit determines that material security issues exist for the Danger Service, T-Mobile may trigger additional assessments or audits during the same calendar year. T-Mobile acknowledges that its affiliate T-Mobile Deutschland GmbH has similar security audit rights and agrees not to exercise its security audit rights under this Section within six (6) months of a T-Mobile Deutschland GmbH security audit; provided T-Mobile has been given access to the results of such recent T-Mobile Deutschland audit.

14.4 T-Mobile Security Requirements. Danger shall have the right to audit T-Mobile network components that have privileged access to the Danger systems and information if there are circumstances that reasonably indicate compromises in the security of such components. Any such audit shall follow the procedures set forth in Section 14.3 for an audit of Danger's network security. T-Mobile shall securely encrypt and safeguard Subscriber passwords and customer care passwords. T-Mobile systems that access the Danger System shall operate at an equal or greater level of security as the Danger Systems that access the T-Mobile network.

14.5 Irreparable Harm. In the event that either party breaches the provisions of Sections 12, 13.3 or 14, the other party is likely to suffer irreparable injuries for which monetary damages will be insufficient. Therefore, in addition to any other remedies provided at law, equity, statute or this Agreement, the non-breaching party will be entitled to injunctive relief, including, without limitation, specific performance of the breaching party's obligations, without the requirement for the posting of a bond or other comparable security. This Section shall survive any termination of this Agreement.

14.6 Law Enforcement. Danger will cooperate with any law enforcement officials and T-Mobile in regard to any law enforcement or investigations as requested by T-Mobile or the applicable law enforcement official.

15. REPRESENTATIONS AND WARRANTIES.

15.1 Each party represents and warrants to the other party that:

(a) it has the full corporate right, power, and authority to enter into this Agreement and to perform its obligations hereunder;

(g) Throughout the applicable Support Period for the Danger Services, and throughout the applicable Software Warranty Period for Danger Software, the Danger Services and the Danger Software will provide and receive all date-related data in an accurate and uninterrupted manner and, without limiting the generality of the foregoing will: (i) provide for data century recognition and calculations accommodating same century and multi-century formulae and date values; (ii) manage and manipulate data involving dates, including single and multi-century scenarios; and (iii) if the Danger Services or Danger Software contain date-related user interface functions or date-related data fields such functions and data fields will indicate date and time.

(h) Notwithstanding anything in this Section 15.2, Danger makes no warranties with respect to software or services provided to Danger directly by T-Mobile ("T-Mobile Software"). If changes in T-Mobile's network cause the Danger Service, Danger Software or Danger Devices to fail to conform to the warranties provided herein or to otherwise malfunction, and T-Mobile failed to notify Danger of such change to T-Mobile's network and did not provide a minimum period of [ * ] to allow Danger to make adjustments for such network changes, then Danger shall not be deemed to be in breach of the warranties in this Section. In addition, Danger shall not be deemed to be in breach of this Agreement if the Danger Service, Danger Software or Danger Devices to fail to conform to the warranties provided herein or to otherwise malfunction as a result of T-Mobile Premium Content. Danger shall not be liable for a failure of the Danger Software or Danger Service to conform to the warranties set forth herein if T-Mobile has provided a written waiver to Danger that expressly waives such warranty and allows Danger to deviate from the warranty.

15.3 Remedy. In the event of a material breach of any of the warranties in Section 15.2(a) � (c), T-Mobile shall notify Danger in writing of such material breach with reasonable detail and Danger shall have a [ * ] period from the date of T-Mobile's notice to repair or replace the Danger Software or Services so that they conform to the foregoing warranties. Only after such [ * ] period has expired and Danger has failed to repair or replace the Danger Software or Services so that they conform to the warranties in Section 15.2(a)-(c), may T-Mobile exercise its rights and remedies as set forth in this Agreement, at law, equity or otherwise with respect to such material breach. Danger shall have no obligation to repair or replace (i) Danger Software that is no longer within the Software Warranty Period and (ii) Danger Services that are no longer within the Support Period. Danger and T-Mobile agree to use an OTA (over the air) upgrade to cure any Danger Software defects wherever technically practicable and commercially reasonable.

15.4 End User Warranty Processing. As between the parties, Danger shall have no obligation to process for Danger Device warranty returns, whether for hardware, Danger Service or Danger Software reasons. T-Mobile shall be responsible for managing (with Manufacturers and their agents) all post-sales support for Subscriber warranty returns, including, but not limited to, in-warranty and out-of-warranty servicing of Danger Device returns and repairs, reverse logistics management, and replacement or "seed-stock" support. This Section 15.4 shall not be construed in a manner that waives T-Mobile's rights under Section 15.2.

15.5 Disclaimer. EXCEPT AS EXPRESSLY PROVIDED OTHERWISE IN THIS AGREEMENT, NEITHER PARTY MAKES ANY WARRANTIES WHATSOEVER WITH RESPECT TO THE DANGER DEVICE, DANGER SERVICE, OR T-MOBILE NETWORK PROVIDED UNDER THIS AGREEMENT, INCLUDING WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

IN THIS AGREEMENT, INCLUDING THE SERVICE LEVEL AGREEMENT, ALL SUCH WARRANTIES ARE HEREBY DISCLAIMED.

16. EXCLUSION OF CONSEQUENTIAL DAMAGES. EXCEPT FOR (i) BREACHES OF SECTION 14.1, 14.2, and 14.3 (CONFIDENTIALITY AND SECURITY), (ii) BREACHES OF SECTION 12.1, 12.2, 12.3, 12.4, 12.5 or 12.6 (INFRINGEMENT OF THE OTHER PARTY's INTELLECTUAL PROPERTY), (iii) AN INTENTIONAL BREACH OF SECTION 13.3(a), (iv) BREACH OF SECTION 15.2(f), AND (v) THE INDEMNITY OBLIGATIONS UNDER SECTION 17, UNDER NO CIRCUMSTANCES WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS OR FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING FROM THE SUBJECT MATTER OF THIS AGREEMENT, REGARDLESS OF THE TYPE OF CLAIM AND EVEN IF THAT PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, SUCH AS, BUT NOT LIMITED TO, LOSS OF REVENUE, LOST DATA, OR ANTICIPATED PROFITS OR LOST BUSINESS.

17. INDEMNITY.

17.1 Danger will hold harmless and indemnify T-Mobile and its current and former subsidiary and parent entities, predecessors, successors, and permitted assigns, and all of their respective current and former officers, directors, members, stockholders, agents, employees, and attorneys (the "Indemnified Parties") from any and all Indemnified Claims. "Indemnified Claims" means any and all actions, causes of action, suits, proceedings, claims, demands, judgments, bona fide settlements, penalties, damages, losses, liabilities, costs, and expenses (including without limitation T-Mobile's reasonable attorneys' fees and costs and those necessary to interpret or enforce this Section 17) arising out of or relating to any third party claim or allegation:

(a) that if true, would establish (i) Danger's breach of this Agreement, including without limitation any of its representations and warranties set forth in Section 15 above; (ii) Danger's misrepresentation, fraud or other willful misconduct in connection with its acts or omissions relating to this Agreement; (iii) the Danger Services or Danger Software contain any material that is unlawful, obscene, or defamatory or violates, infringes, or misappropriates any Intellectual Property Right or any other right of any third party; or (iv) any wrongful use or unauthorized disclosure of Subscriber Data by Danger; and

(b) that arises out of (i) any act or omission of Danger or Danger's subcontractors or agents relating in any way to Danger's performance or obligations under this Agreement; or (ii) the bodily injury or death of any person, or the loss of or damage to the property of any person, that results from the use of the Danger Services; or (iii) any alleged error, problem, defect or malfunction related to the design of any Danger Service.

(c) Notwithstanding anything in this Section 17, Danger shall have no obligation to indemnify or defend T-Mobile for any Indemnified Claim alleging that the T-Mobile Software or T-Mobile Premium Content is unlawful, obscene, defamatory, or violates, infringes or misappropriates any Intellectual Property Right or any other right of any third party.

17.2 Danger will defend the Indemnified Parties from any and all Indemnified Claims. Danger will pay all reasonable attorney and expert fees and costs relating to such defense and will conduct all steps or proceedings in connection with such defense and as required to settle or defend such Indemnified Claims, including without limitation the employment of counsel reasonably satisfactory to T-Mobile. Danger shall have the primary control of the defense of any Indemnified Claim but may not take any steps that

28.

Execution Copy

T-Mobile and Danger Confidential

would cause T-Mobile to admit liability or affect T-Mobile's rights or interests in any legal action without T-Mobile's prior written consent. At all times, T-Mobile may participate in the defense using its own legal counsel, and at its own expense. T-Mobile may, however, by providing notice to Danger, assume sole and exclusive control of such defense and settlement at its own cost (including without limitation by employing the same counsel or different counsel reasonably satisfactory to both T-Mobile and Danger), provided that T-Mobile will not enter into any settlement that affects Danger's rights or interests without the prior written consent of Danger.

17.3 T-Mobile will provide Danger with reasonably prompt written notice of any Indemnified Claim. At Danger's expense, T-Mobile will provide reasonable cooperation to Danger in connection with the defense or settlement of any such claim. Danger may not settle any Indemnified Claim on T-Mobile's behalf without first obtaining T-Mobile's written permission, which permission will not be unreasonably withheld. Danger will make any payments required of it under this Section 17.3 on T-Mobile's demand. Following T-Mobile's request, Danger will not disclose such settlement and its terms to any third party, directly or indirectly, without T-Mobile's prior, written permission or an order from a court of competent jurisdiction; provided however, Danger may provide such information to its auditors, attorneys, investors and financial advisors that are bound in writing to keep information of this nature confidential.

17.4 T-Mobile will hold harmless and indemnify Danger and its current and former subsidiary and parent entities, predecessors, successors, Affiliates, and assigns, and all of their respective current and former officers, directors, members, stockholders, agents, employees, and attorneys from any and all actions, causes of action, suits, proceedings, claims, demands, judgments, bona fide settlements, penalties, damages, losses, liabilities, costs, and expenses (including without limitation Danger's reasonable attorneys' fees and costs and those necessary to interpret or enforce this Section 17) arising out of or relating to any third party claim or allegation relating to (i) T-Mobile's breach of this agreement, (ii) an outage or interruption of T-Mobile's network, or (iii) the T-Mobile Software or a T-Mobile Premium Service that is either provided directly by T-Mobile or by a third party with whom T-Mobile has contracted to provide services via Danger Devices where the claim relates to either (a) the alleged infringement of a third party's intellectual property right by some component of such T-Mobile Software or T-Mobile Premium Service, or (b) damages or liability that is attributable to such T-Mobile Software or T-Mobile Premium Service. T-Mobile may choose to have the primary control of the defense of any claim under this Section, but may not take any steps that would cause Danger to admit liability or affect Danger's rights in any legal action without Danger's prior written consent. At all times, Danger may participate in the defense using its own legal counsel, and at its own expense. T-Mobile may not settle any claim or action on Danger's behalf without first obtaining Danger's written permission, which permission will not be unreasonably withheld. T-Mobile will make any payments required of it under this Section 17.4 on Danger's demand. Following Danger's request for indemnification, T-Mobile will not disclose such settlement and its terms to any third party, directly or indirectly, without Danger's prior, written permission or an order from a court of competent jurisdiction; provided however, T-Mobile may provide such information to its auditors, attorneys, investors and financial advisors that are bound in writing to keep information of this nature confidential.

17.5 Notwithstanding the foregoing, neither party shall indemnify the other for third party claims to the extent to which an end user is found liable for his/her intentionally harmful or negligent use of the Danger Device, Danger Software, Danger Service, the T-Mobile Software, or a T-Mobile Service.

18. INFRINGEMENT REMEDY. If the Danger Services or the Danger Software (or any portion thereof), are held or reasonably determined (by Danger) to constitute an infringement and any use as contemplated by this Agreement is enjoined or imminently likely to be enjoined, Danger will notify T-Mobile and immediately, at Danger's expense either: (i) procure for T-Mobile and its Subscribers the right to continued use as contemplated by this Agreement of the affected Danger Services or Danger Software (or portion thereof); or (ii) provide T-Mobile with a replacement or modified version of the affected Danger Services or Danger Software (or portion thereof) that is non-infringing, provided that the replacement or modified version meets the applicable specification and is provided to T-Mobile in its entirety and in advance of distribution sufficient to allow T-Mobile to evaluate and approve the substitution.

5. Danger Service Availability, Metrics and Credits.

5.1 Outage Measurement. An Outage for Danger Service availability will be measured from the time Danger receives notice of such Outage or Danger recognizes the Outage, whichever occurs first, until all Danger Services are restored.

5.2 Danger Service Availability. The Service Threshold for the availability of the Danger Service shall not fall below [ * ]% as calculated monthly. Compliance with the Service Threshold will be measured based on a calendar month Measurement Periods. The Service Threshold percentage will be calculated by dividing the total number of minutes of Outages during an applicable month by the total number of actual minutes (excluding the minutes within the Scheduled Maintenance Windows) in such month, and then subtracting the resulting number from 1 and multiplying that amount by 100; i.e., a calculation using the following formula: 1- (total Outage minutes in a month/total minutes in said month) x 100. Outages caused by technical problems within T-Mobile's network or that are outside of Danger control (each an "External Problem") shall be excluded from the calculation for the duration of the External Problem. In addition, Danger's restoration time from such External Problems shall be excluded from the calculation in accordance with the following formula: (i) for External Problems that are [ * ], then the restoration time not considered an "Outage" will be equal to [ * ] the time of the External Problem (e.g., if T-Mobile's network caused a [ * ], then restoration time of [ * ] would not be considered an "Outage"), (ii) for External Problems that are greater than [ * ], then the restoration time not considered an "Outage" will be [ * ], plus an amount of additional time equal to [ * ] (e.g., if T-Mobile's network was down for [ * ], then the restoration time would be [ * ])). If the Service Threshold falls below [ * ]% during a Measurement Period, T-Mobile will be entitled to a prospective credit from Danger towards Service Fees. The credit will be calculated as follows: [ * ]. If the Service Threshold falls below [ * ]% during a Measurement Period, T-Mobile will be entitled to a credit from Danger of [ * ]% of the Service Fees paid or payable by T-Mobile for the Measurement Period. The service credits set forth above shall constitute T-Mobile's sole and exclusive monetary remedy for Danger's failure to maintain the Service Threshold. T-Mobile shall be permitted to withhold payments in the amounts equal to the credits due under this Section 5.2 from amounts owed to Danger for Service Fees. Danger shall issue credit memos for Outages to T-Mobile within ten (10) business days from the end of each calendar month in which a credit was earned.

6. Application Specific Performance KPIs. The parties have set forth below key performance indicators ("Key Performance Indicators" or "KPIs") for performance of e-mail, web browsing delivery and instant messaging services. Until such time that real-time network performance can be determined, the Service-Based KPIs will be used to determine Degradations. For all KPIs, the Degradation and Severe Degradation calculations as determined below will not include degradations caused by technical problems within T-Mobile's network or that are outside of Danger control (each an "External Degradations") for the duration of the External Degradation. In addition, Danger's restoration time from such External Degradation shall be excluded from the calculation in accordance with the following formula: (i) for External Degradations that are [ * ], then the restoration time not considered an "Outage" will be equal to [ * ] the time of the External Degradation (e.g., if T-Mobile's network caused a degradation for [ * ], then restoration time of [ * ] would not be considered a "Degradation"), (ii) for degradations outside of Danger's control that are greater than [ * ], then the restoration time not considered a "Degradation" will be [ * ], plus an amount of additional time equal to [ * ] (e.g., if T-Mobile's network was down/degraded for [ * ], then the restoration time would be [ * ])).

6.1 KPI Tools.

(a) Device-Based KPI Tool. Danger has developed a device-based KPI tool for end-to-end, round trip performance measurements of e-mail and Web browsing. T-Mobile has two (2) such devices in its possession, and by March 1, 2006 Danger shall load such tools onto four (4) additional Danger Devices provided by T-Mobile. These tools will be used by T-Mobile to self-monitor the performance of the end-to-end customer experience of the Danger Service. Although it can and should be used to help determine the source of potential issues, information and data collected from this tool will not be used as a measurement against the agreed upon Service Level Metrics or credits because it measures T-Mobile data network and the Internet which are elements outside of Danger's control.

(b) Service-Based KPI Tool. Danger has developed and is testing a service-based KPI tool for measurements of e-mail and web browsing performance within the Danger Service (the "Service-Based KPI Tool"). This tool collects data utilizing a server which is placed on the edge of Danger's network. For email performance the service-based KPI tool will send and receive test messages at regular intervals. For web browsing performance the tool requests and retrieves copies of web pages that are located within Danger facilities. The e-mail messages and web traffic will traverse the same path as is traversed by Subscribers, within the Danger Service. Danger shall report results from the Service-Based KPI Tool monthly, beginning with the month-end report for March 2006. Unless otherwise agreed by the parties, the Service-Based KPI Tool reports will be the basis of the Service Level Metrics and credit calculations.

6.2 Email.

E-Mail reliability metrics shall have a fixed target of [ * ]% delivery of email content within a [ * ] [ * ] time period, with credits to apply if less than [ * ]% of emails are delivered within [ * ] [ * ]. Metrics for purposes of calculating credits shall be based on tests that measure @tmail.com email performance. For reliability of less than [ * ]% during a Measurement Period, the prospective credit shall be a percentage of the Service Fees paid by T-Mobile for the Measurement Period, as set forth in the table below. The parties acknowledge the email technology may be subject to further changes in the future, and that new performance metrics may be appropriate if new technology is introduced (e.g. spam filtering). The parties will agree whether existing metrics should be changed, or not, at such time.

(a) Web proxy error rates should not exceed [ * ]% overall for the month. For web proxy error rates exceeding [ * ]% for the Measurement Period, during a Measurement Period, the prospective credit shall be a percentage of the Service Fees paid by T-Mobile for the Measurement Period, as set forth in the table below. Danger shall report its results monthly. Error information will come from real customer data from the Danger Service.

(b) Following the evaluation of round-trip web page retrieval times, Danger will use reasonable efforts to correct any deficiencies found and the parties will agree on similarly-structured metrics for the retrieval of one or more sample web pages. Danger shall report its results monthly but also must provide T-Mobile real-time access to the data collection tool or read-only access to the measured results via a dashboard or other real-time means. It is anticipated that a copy of [ * ] shall be one of the sites, and that another site will also be chosen, possibly [ * ] or some other popular site. It is acknowledged that times for some web sites are expected to increase with the new browser, because the new browser will read JavaScript pages, where the old browser did not. The new browser is expected to deliver at least statistically similar performance to the old browser for non-JavaScript sites like [ * ], if not improved performance.

(c) The parties acknowledge the browser technology may be subject to further changes in the future, and that new performance metrics may be appropriate if new technology is introduced. The parties will agree whether existing metrics should be changed, or not, at such time.

6.4 Instant Messaging. The parties will work together to develop KPI measurement tools for instant messaging services, taking into account the third party services involved.

6.5 Maximum Credits. Except as set forth in this Section or Section 6.6, in no instance shall the total credits from all Application Specific KPIs exceed [ * ]% of Service Fees (no more than [ * ]% per Application) in any given Measurement Period. Provided that the calculated Application specific credits under this Section 6 are not greater than the Danger Service Outage credits under Section 5, the application specific KPI credits will not be available if Danger Service Outage credits under Section 5 are invoked, or if Application Severe Degradation credits are earned, as described in Section 6.6. The parties agree to update Application specific metrics in accordance with improvements that may be driven through customer complaints or other T-Mobile observations, in the event that these complaints/observations reveal an area of degraded service that is not currently measured by already agreed Key Performance Indices. T-Mobile reserves the right to seek reasonable credits for customer impacting service outages or service degradation that are not expressly described herein of up to [ * ]% of Service Fees paid by T-Mobile for a Measurement Period. T-Mobile may not, however, withhold payment in advance of gaining agreement with Danger that such credits are reasonable and appropriate. The Service Fee credits set forth in this Section 6 shall constitute T-Mobile's sole and exclusive monetary remedy for Application-specific Degradations and Severe Degradations and Danger's failure to maintain the application specific KPIs. T-Mobile shall be permitted to withhold payments in the amounts equal to the credits due under Section 6 from amounts owed to Danger for Service Fees. Danger shall issue credit memos for Application-Specific Degradations and/or Severe Degradations to T-Mobile within ten (10) business days from the end of each calendar month in which a credit was earned.

6.6 Application Specific Severe Degradation. If there is Severe Degradation (as defined below) of email, web browsing, or instant messaging (each an "Application"), then T-Mobile shall be entitled to a credit of [ * ]% of Service Fees paid by T-Mobile for the day on which the Severe Degradation occurred, for each Application that is Severely Degraded. Under no circumstances will T-Mobile be entitled to a credit larger than [ * ] percent ([ * ]%) of the Service Fees per day for Severe Degradations.

(a) Email Application Severe Degradation. The Email Application will be considered to be Severely Degraded for a day if [ * ] or more of the test results from the Device-Based KPI Tools and Service-Based KPI Tools for that day show a failure to complete email delivery within [ * ] [ * ].

(b) Web Browsing Application Severe Degradation. The Web Browsing Application will be considered to be Severely Degraded if there is an error rate of [ * ]% or more attempt failures within [ * ].

(c) IM Application Severe Degradation. The IM Application will be considered to be Severely Degraded for [ * ] if [ * ] of the test results from Device-based KPI or Service-based KPI Tools for that [ * ] [ * ], and such failure is not the cause of a third party IM service provider or T-Mobile.

6.7 Pro-Rata Metrics. The parties shall also see to establish metrics to measure Outages as a percentage of customer hours, with corresponding refunds/credits of service fees for the month. The effected customers, as a % of total base, will be used to pro-rata service fees. For example: email outage for [ * ] customers = [ * ].

6.8 Audit Rights for Application Specific Measurements. T-Mobile may, pursuant to its audit rights in Section 10.8 of the Agreement, audit Danger's measurements and collection practices for the KPIs described in this Section 6. Notwithstanding Section 10.8, if T-Mobile conducts an audit solely on the measurement and collection practices issue, such audit will not count against the annual number of audits permitted under Section 10.8. But T-Mobile may only conduct a measurements and collection practices audit one time per year unless an audit indicates inaccurate reporting, in which case, T-Mobile may conduct an additional audit. The Audit report and results shall be subject to a confidentiality agreement provided by Danger. If Danger refuses to make its data or facilities available to an audit under this Section 6.8, then such time during which Danger refuses to allow an audit will be [ * ].

Danger will identify the consultants and provide information regarding their background to T-Mobile. If T-Mobile objects in good faith to the consultant, T-Mobile must support the objection with an articulable basis that disputes the consultant's objectivity or competence to conduct such review. If such an objection is raised, then that consultant will not be used for the System Architecture Review, and Danger and/or T-Mobile will identify a new proposed consultant subject to the objection process in this section. T-Mobile will have full access to a meaningful and detailed executive summary report provided by the consultant(s) regarding all of the foregoing issues. If T-Mobile requests additional detail regarding the System Architecture Review, then Danger will provide such detail, with such detail not to be unreasonably withheld. At T-Mobile's request, T-Mobile may request that the full System Architecture Review be reviewed by a third party, who must be reasonably approved by Danger, for the purpose of confirming that the summary provided to T-Mobile is an accurate summary of the System Architecture Review. Such third party will be required to sign a confidentiality agreement with Danger.

Schedule 1 To SLA: Enhanced Monitoring And Reporting

8. T-Mobile Requested Minimum Requirements. The following represents T-Mobile's requested minimum monitoring and reporting items that Danger will provide as enhanced monitoring. Danger will create specifications, estimate timing for delivery, and provide proposed shared NRE pricing, if any, for development and incorporation into the Danger Service release schedule in accordance with the Schedule set forth in Section 2.

a. Device-Based KPI Tool.

i) Up to [ * ] Devices � to be delivered in stages, subject to mutual agreement on delivery timing and cost.

ii) E-Mail- uses the T-Mobile network to represent the end to end customer experience for @tmail. This test method measures the timing of a full round trip for an email, including sending and receiving the email.

iii) Web Proxy - uses the T-Mobile network to represent the end-to-end customer experience. Within the test session, the Device-Based KPI Tool requests and retrieves a few of the most popular websites accessed by T-Mobile Subscribers. The web pages used should be configurable as mutually agreed upon. This test method measures the time it takes to request, retrieve and display the web page. The measurement period for this test case is currently set at [ * ]. The success/failure threshold shall be measured at [ * ].

iv) Instant Messaging - uses the T-Mobile network to represent the end-to-end customer experience. Within the test session, the KPI application would log on to the various IM services including AIM and Yahoo Messenger. The measures for success or fail should depend on ability to log on to the messenger service. Failures would be �Server Timeouts�, �Connection Failures�, etc. This test method therefore measures the total number of successful and failed logins in a period of time. Danger will use reasonable efforts to develop an IM Device-Based KPI tool as described in this Section (1)(a)(iv), but if it is unable to, Danger shall use reasonable efforts to develop (within the applicable time frame) a suitable alternative that is reasonably acceptable to T-Mobile.

b. Near Real-Time Portal. Danger will create a "portal" where T-Mobile can retrieve reports on application performance on a near real-time basis. Data would be reported on at least a 1 hour interval, and may be quicker depending on the particular report or metric.

i) E-Mail � will measure delivery time of simulated emails that are measured from the entry point of the Danger Service, through the Service, and back to the entry point. Reports will show delivery times of the simulated emails.

ii) Web Proxy � will measure web page fetching performance for simulated queries from the entry point of the Danger Service, through the Service, and back to the entry point. Reports will show the fetching performance of the simulated queries.

c. Real Customer Data and Aggregate Data Reporting. Danger will create periodic reports which would be posted on a monthly basis within ten (10) business days after the end of the month to the T-Mobile accessible portal.

T-Mobile and Danger will periodically review proposed Danger Premium Content and T-Mobile will identify the proposed Danger Premium Content that it approves. If T-Mobile approves of such Danger Premium Content, then T-Mobile will use commercially reasonable efforts to launch such Content, with a launch date no later than sixty (60) days after T-Mobile's approval or Danger's Certification, whichever is later. Subject to the expedited take-down requests in this Section 3(b), or the removal of Content provisions in Section 3(c), T-Mobile will maintain any approved Danger Premium Content on the Danger Device for no less than six (6) months from its launch date. T-Mobile may, at its sole discretion, create a "What's New" folder in the PDM for the purpose of promoting newly added Premium Content. If T-Mobile creates a "What's New" folder, and if Danger launches a new item of Danger Premium Content during a month, then T-Mobile shall promote the availability of at a minimum of [ * ] piece of the new Danger Premium Content available that month by placing it in the "What's New" folder in the Catalog application for a minimum of [ * ] after initial commercial launch of such content. Upon request by T-Mobile, Danger will take down such item of Premium Content within a commercially reasonable period of time; provided, however, if T-Mobile requests an expedited take-down period, Danger will use commercially reasonable efforts to take down the Premium Content as quickly as possible, but no later than one (1) business day following T-Mobile's request (e.g., T-Mobile is required by a third party content provider or government order to remove Content on an expedited basis). Notwithstanding the preceding sentence and except as permitted under Section 6(c)(iii), T-Mobile may not request take-down of any item of Danger Premium Content during the [ * ] following the commercial launch of such Danger Premium Content.

(ii) T-Mobile Premium Content. Danger may reject proposed T-Mobile Premium Content, or remove from the catalog and suspend the server-side functionality of any Approved T-Mobile Premium Content from the Premium Download Manager that, in Danger's reasonable discretion, threatens the security or stability of the Danger Service, Danger Device, or Basic Services. Notwithstanding the preceding sentence, prior to removing any T-Mobile Premium Content, Danger will use commercially reasonable efforts to contact T-Mobile in order to request approval of such removal.

Re: Content Control Development Statement of Work

Dear Warren:

This letter sets forth the agreement between Danger, Inc. ("Danger") and T-Mobile USA, Inc. ("T-Mobile") regarding the development and operation of a solution for Danger Devices to restrict access to adult oriented, Internet websites.

This letter shall be part of and governed by the terms of the Master Services Agreement ("Agreement"), effective as of June 1, 2005 between Danger and T-Mobile. In the event of any conflicts between this letter and such Agreement, this letter (including all attached exhibits to the letter) shall govern to the extent of the conflict. Capitalized terms not defined herein shall have the meaning set forth in the Agreement.

1. Definitions.

"Content Control" means the feature Subscribers can elect which restricts web browser access to adult-oriented material, as defined by T-Mobile.

"Content Control Test" means a test which runs continuously and monitors whether selected adult-oriented websites are being correctly filtered.

"Content Control Platform" means a group of servers and associated equipment owned by T-Mobile upon which the Content Control Platform Software operates.

"Content Control Platform Software" means third party software which will query a URL database to determine whether a URL is accessible or non-accessible to Subscribers who elect Content Control.

"Data Center" means the Verizon data center in San Jose, California.

"Integration Proxy" means an application that runs on the Danger System, which interfaces with the T-Mobile Partner Publisher, and handles Subscriber status, passwords, content changes and MSISDNs.

"Partner Publisher" means a T-Mobile application which interfaces with the Integration Proxy and exchanges Subscriber information, including whether a Subscriber has elected Content Control.

"Verizon" means Verizon Business Financial Management Group (formerly "MCI Communications Services, Inc.").

2. Scope of Work

A. Danger Obligations.

(i) Integration Proxy development. Danger will modify the Integration Proxy and other related software components which run on the Danger System to read a flag provided by the Partner Publisher that indicates whether a Subscriber has elected Content Control.

(ii) Danger Support Tool development. Danger will modify the Danger Support Tool so that a T-Mobile employee may view or modify, on a per Subscriber basis, a Subscriber's status regarding their election of Content Control.

(iii) Subscriber traffic routing. Danger will route Subscribers' web browser traffic based on the Subscriber information provided by T-Mobile via the Partner Publisher or the Danger Support Tool. Specifically, if the Subscriber elects Content Control, then Danger will send the web browser traffic to the Content Control Platform. If the Subscriber does not elect Content Control, Danger will process the web browser traffic as normal and not route the web browser traffic to the Content Control Platform.

(iv) Content Control Test development and operation. Danger will create and operate the Content Control Test.

(v) Operational support. Danger will provide operational support services as set forth in Exhibit A.

(vi) Housing the Content Control Platform. Danger will house the Content Control Platform at the Data Center, provided there is enough equipment storage space and infrastructure services necessary for the Content Control Platform. Danger will provide T-Mobile with reasonable commercial notice if the Content Control Platform is unable to be housed at the Data Center. Following such notice, the parties will mutually agree upon a new location to house the Content Control Platform and new terms for housing the Content Control Platform at a new location.

B. T-Mobile Obligations.

(i) Subscriber Information. Subscriber information provided by T-Mobile to Danger will include all information needed for Content Control, including whether the Subscriber has elected Content Control. The Partner Publisher will push Subscriber information to the Integration Proxy. The Integration Proxy will not actively query T-Mobile for such information. The parties understand that Danger will rely on accurate Subscriber information for Content Control to be effective. T-Mobile shall make its best commercial efforts to deliver accurate Subscriber information. Danger will not be responsible for any failures to comply with its obligations under subsection 2.A (iii) of this letter if Subscriber information is inaccurate.

(ii) Content Control Platform Software. Residing on the Content Control Platform will be the Content Control Platform Software. T-Mobile is responsible for paying for and obtaining all licenses to use the Content Control Platform Software on the Content Control Platform. T-Mobile (or a third party acting on T-Mobile's behalf) will install, maintain and update the Content Control Platform Software to ensure the Content Control Platform Software correctly filters traffic. For avoidance of doubt, Danger will have no obligation to install, maintain or update the Content Control Platform Software.

(iii) Content Control Platform. T-Mobile is responsible for purchasing and supplying the Content Control Platform. T-Mobile will establish and ensure adequate capacity for, but not limited to, the Content Control Platform Software and other components necessarily residing on the Content Control Platform.

(iv) Operational Support. T-Mobile will provide operational support services as set forth in Exhibit A.

3. VPN connection. The parties will work together to maintain a continuous VPN (or subsequently T1 dedicated line) connection with suitable architecture and alarming. Danger will use the VPN connection in connection with performing its Tier 1 obligations as set forth in Exhibit A. The VPN connection will also be used to allow T-Mobile to maintain and repair Tier 2 related problems with the Content Control Platform.

4. Danger Devices Supported. At the time of commercial launch of Content Control, the Danger Devices known as the Sidekick II and the Sidekick3 will support Content Control. All future Danger Devices will be supported.

5. Ownership. T-Mobile acknowledges that Danger will make modifications to the Integration Proxy and other components on the Danger System and that Danger shall retains all rights, title and interest in and to such modifications. As between Danger and T-Mobile, T-Mobile and/or its licensors and service partners own the Content Control Platform.

6. Service Levels. Danger and T-Mobile will adhere to the response times and perform the tasks set forth in Exhibit A to this letter.

7. Schedule. The schedule for development, certification, testing and launch is set forth in Exhibit B to this letter. Danger and T-Mobile acknowledge that each party's responsibilities are contingent on the other party fulfilling its obligations. Neither party shall be in breach of this letter for any delay or failure that results from the delay or failure of the other party, and any delivery dates for a particular party shall be equitably extended to compensate for delays or failures of the other party. In addition, no penalties or reductions in amounts to be paid shall be made for failures to meet the development and launch schedule unless mutually agreed upon in writing by the parties following execution of this letter.

8. Payment. T-Mobile shall pay the amounts set forth in Exhibit C upon the earlier of (i) T-Mobile's acceptance of the deliverables outlined in 2.A (i), (ii), (iii) and (iv),

such acceptance not to be unreasonably withheld; or (ii) by the date of first commercial launch of Content Control. No further payment shall be required in the event any development is necessary to enable Content Control for the Prepaid Danger Service.

9. Disclaimer. T-Mobile acknowledges that technical problems or failures may occur from time to time, and that Subscribers who elect Content Control may be able to access Internet websites that would have been blocked or restricted absent such problems or failures. Danger will use reasonable commercial efforts to prevent such problems or failures, but Danger does not represent, warrant or guarantee that implementation of Content Control on the Danger System will be error-free. Nothing herein is intended to modify any disclaimer or warranty provisions set forth in the Agreement.

Please indicate your agreement with the terms set forth in this letter by signing below.

Tier 1 Roles


	Issue	Solution
1	Who will monitor the Content Control Platform and the Content Control Platform Software?	T-Mobile will monitor the Content Control Platform and Content Control Platform Software in an identical fashion to the way they monitor Content Control for their general customer base. In addition, however, Danger will create and operate the Content Control Test.

2	Who performs alarming, and for what?	Danger will monitor connections and traffic up to the load balancer associated with the Content Control Platform. Danger will alarm for tests as described in #1 above, and will contact T-Mobile's NOC (Tier 1) immediately upon determining that incorrect results are being returned.

3	Who will undertake the first level of trouble shooting with regard to content issues that are escalated from T-Mobile to ensure that the issue is not related to other Danger network applications?	Danger will undertake troubleshooting of all elements except the Content Control Platform and the Content Control Platform Software itself, which is the sole responsibility of T-Mobile. In the event that Danger identifies an issue with its browsing platform, Danger will report the issue to T-Mobile and its resolution for tracking purposes. Danger will remind the T-Mobile NOC that they may be seeing alerts on T-Mobile's content filtering monitoring solution, in the event such an issue arises. In the event T-Mobile identifies trouble with the Content Control Platform, T-Mobile will report the issue to the Danger NOC, and T-Mobile Tier 1 will either resolve directly or escalate to T-Mobile Tier 2, as appropriate. NOTE: Either side will notify the other of planned maintenances, consistent with existing practices, to prevent wasted troubleshooting efforts.

4	Who will respond to Tier 1 Alerts?	As described above.

5	Who will escalate to Tier 2 for trouble resolution, and who will handle Tier 2 problems?	T-Mobile will be handling Tier 2. T-Mobile will escalate to Tier 2 in the identical fashion that they escalate for their primary solution.


6	Who may call for troubleshooting conference bridges to be opened as appropriate?	Either party may call for a troubleshooting bridge to be opened.

7	How will application support VPN access to the Content Control Platform work?	T-Mobile and Danger will maintain a VPN (or subsequently a T1) connection that is kept up and running continuously, with suitable architecture and alarming to ensure uptime of the connection.

Management of On-site/Remote Tier1 Technical Services


	Issue	Solution
1	Who troubleshoots network components or call flow issues?	Danger will be responsible for the edge�from the cross connects to the F5.

2	Who provides routine connectivity and power verification?	Danger will perform this function

3	Who identifies physical issues, and who repairs them?	T-Mobile expects it will be able to find these issues in most cases with remote diagnostics; Danger will provide physical remote-hands support as needed.

4	Who perform hard reboots?	T-Mobile will have the ability to do this remotely as needed; if this fails Danger will provide physical remote-hands support

5	Who replaces subassemblies?	Danger will do this generally on a next business day basis, unless business need indicates greater urgency.

6	Who handles onsite preventive and routine maintenance?	If this is needed Danger can provide such maintenance with guidance from T-Mobile.

7	Who will provide emergency 24x7x365 on-site support?	Danger will provide as needed

8	Who will provide RMA support?	Danger will do this generally on a next business day basis, unless business need indicates greater urgency.

9	Who will facilitate application support data center access 24x7x365 in event of emergency?	Danger will facilitate this if it is needed

10	Who will facilitate hardware vendor data center access 24x7x365 in event of emergency?	Danger will facilitate this if it is needed

Tier 2 Escalation

In the event that Danger needs to escalate to T-Mobile, the following section lays out the methods. Initially, the most likely trigger for an escalation will be the failure of Danger's Content Control Test. Additionally, as stated earlier, Danger will notify T-Mobile whenever there is an issue with the Danger Service to avoid wasted troubleshooting by T-Mobile.

When applicable, Danger shall escalate to the T-Mobile designated (Tier 1) support team. Danger shall provide at a minimum the following:

Caller Name

Call back number

Trouble ticket number

Severity of trouble ticket

Description of trouble, alarms, test results, etc.

Corrective actions taken by Danger

Assist with VPN access if needed

Appendix A

Content Launch Process

1. Danger Sourced Content Default. The parties intend that Danger will act as the principal sourcing point for Certain Premium Content. As such, if T-Mobile desires to include a particular item of Certain Premium Content within the Premium Download Manager and Danger already has a license for such item of Certain Premium Content, the item will not be T-Mobile Sourced Certain Premium Content under this Amendment, unless such item falls within the "T-Mobile Exception" outlined in Section 3 of this Appendix A. For the avoidance of doubt, T-Mobile may provide T-Mobile Sourced Certain Premium Content if Danger does not have rights to license a particular item of Certain Premium Content or if the item falls within the T-Mobile Exception. If Danger later obtains rights to a particular item of T-Mobile Sourced Certain Premium Content and the item does not fall within the T-Mobile Exception, the item of content will be deemed Danger Sourced Certain Premium Content under the Agreement. If an item is deemed Danger Sourced Certain Premium Content under the preceding sentence or otherwise, the change will become effective on the first day of the next calendar month. For proposed Danger Sourced Certain Premium Content, Danger will use commercially reasonable efforts to acquire all necessary rights to distribute the Danger Sourced Certain Premium Content for a minimum of [ * ] from the release of such content. If Danger does not have the necessary rights for the proposed Danger Sourced Certain Premium Content to be distributed for a minimum of [ * ], then prior to T-Mobile's consideration and approval of such item of content, Danger will provide notice to T-Mobile in the Pipeline Overview Document described in Section 4A of this Appendix of the length of time that such Danger Sourced Certain Premium Content may be distributed. Danger will not collect any Backend Revenues in connection with any Danger Sourced Premium Content without T-Mobile's prior written approval (email from a T-Mobile employee with the title of director level or above within T-Mobile's product development or marketing group). The parties hereby approve of the IP Relay titles from [ * ] and [ * ] as Premium Content subject to the Backend Revenues share. If Danger receives Backend Revenues for items of Premium Content, Danger will pay T-Mobile a share of the Backend Revenues in accordance with Appendix B. If Danger initiates a promotional activity that does not involve Premium Content, Danger will pay T-Mobile a share of the Backend Revenues in accordance with Appendix B. If T-Mobile wishes to distribute T-Mobile Sourced Certain Premium Content to Subscribers for free or at discounted rate and, , collect additional revenues from a third party content provider, T-Mobile and Danger will work in good faith to mutually agree to an appropriate model for compensating Danger in lieu of the revenue shares outlined in Appendix B Notwithstanding the foregoing, Danger acknowledges and agrees that it will provide support for the development and certification of such T-Mobile Sourced Certain Premium Content as long as the parties are engaged in discussions regarding compensation pursuant to the preceding sentence. Absent reaching an agreement for compensating Danger prior to launch, T-Mobile may choose to either delay launch pending the parties' mutual agreement or require Danger to launch such Premium Content (if otherwise certified), subject to the following sentence. If [ * ] following launch the parties have not mutually agreed on the compensation for Danger for such T-Mobile Sourced Certain Premium Content, the parties shall escalate the discussion to their respective senior management, and if the parties have not reached an agreement on compensating Danger [ * ] following the launch, Danger may remove such Premium Content from the PDM and discontinue support for such Premium Application. For the avoidance of doubt, if T-Mobile collects revenues from a third party for T-Mobile Sourced Certain Premium Content that is not offered for free or at a discounted rate, T-Mobile will not be required to discuss any alternative compensation for Danger unless such Premium Content offers functionality that requires Danger to provide

significant additional development or certification support as compared to Premium Content of the same general type.

2. T-Mobile Referrals. If T-Mobile desires to license Certain Premium Content from a particular content provider (except in the case of content providers that fall within the T-Mobile Exception), T-Mobile will notify Danger and introduce Danger to the provider if needed. At the time of T-Mobile's notification, T-Mobile will indicate whether the provider is "high priority." Danger will use commercially reasonable efforts to enter into licensing agreements with each content provider that T-Mobile designates as "high priority" within [ * ] days. For all other providers, Danger will pursue licensing agreements in its discretion. Danger will notify T-Mobile as to whether it plans to pursue a relationship with all non-high priority providers or whether it needs more time to investigate such a relationship within [ * ] days.

3. T-Mobile Exception. T-Mobile will not be required to source through Danger and may license directly ("T-Mobile Exception"): (i) Certain Premium Content if T-Mobile enters into a relationship which it deems, in its sole discretion, a corporate strategic initiative (e.g., a sponsorship or promotional deal) with the content provider or (ii) in the case of Backgrounds and Themes, the content provider is one of the four (4) [ * ] (e.g., [ * ]). With respect to each item of T-Mobile Sourced Certain Premium Content, T-Mobile shall notify Danger and, to the extent T-Mobile deems necessary, introduce Danger to the provider, as set forth in more detail in Section 2 above. If T-Mobile deems a particular provider to be strategic and within the scope of the T-Mobile Exception, T-Mobile will notify Danger and Danger will not engage in discussions with such provider about sourcing content for T-Mobile. Danger will provide certification support to the content providers of T-Mobile Sourced Certain Premium Content.

4. Commercial Deployment of Certain Premium Content in the Premium Download Manager.

A. Pipeline Overview Document and Monthly Meetings. Danger will maintain a spreadsheet with a summary of all titles of Certain Premium Content that are in development as well as prospective concepts for review ("Pipeline Overview Document"). Danger makes items of Certain Premium Content available on a when-and-if available basis. The Pipeline Overview Document is not a binding commitment to launch an item of content or guarantee that Danger has the rights to launch an item of content. The Pipeline Overview Document will contain both T-Mobile Sourced and Danger Sourced Certain Premium Content. For each item, the Pipeline Overview Document will contain title; provider; suggested retail pricing, anticipated Average Network Usage Per User classification (e.g. [ * ]) for Applications; applicable device(s); proposed revenue share classification (e.g., Standard/Premium); proposed "Tier" classification under table 1 set forth below for all titles that are classified as "Tier 1" or "Tier 2;" a one-page overview description of the title; file size of the title if available; any "non-standard" license terms (e.g. special promotional requirements; an initial license term of less than [ * ]); the license status of each title (e.g. whether Danger has the rights to launch); and a target publication date. The Pipeline Overview Document will be provided to T-Mobile on a monthly basis in connection with monthly pipeline review meetings to be held on-site at T-Mobile or via phone with representatives of both parties in attendance T-Mobile will use commercially reasonable efforts to review and provide feedback on the Pipeline Overview Document within [ * ] business days following each monthly pipeline review meeting and approve on the Pipeline Overview Document the following: content providers and titles that are "high priority," titles T-Mobile will pay Premium pricing for, Danger's proposed Tier and anticipated Average Network Usage Per User classifications, and titles T-Mobile would like Danger to proceed with testing and move towards commercial launch. For titles that fall within Tier 1, if T-Mobile does not respond to Danger within the [ * ] business day period or if T-Mobile's response does not indicate that T-

Mobile does not want Danger to move forward with testing, Danger may consider the title approved, subject to the terms set forth in Section 4.C. of this Appendix A. Danger will not launch any Tier 2 title unless T-Mobile expressly indicates in the Pipeline Overview Document that the title has been approved. If, at any time after the approval of a title in the Pipeline Overview Document T-Mobile changes its mind with regard to a specific title or designation, T-Mobile shall promptly notify Danger of such change in writing (email is acceptable).

B. New Product and Platform Innovation. The parties desire to evolve the Premium Content product offering and platform. To encourage such innovation, the parties shall periodically meet to discuss T-Mobile's and Danger's long-term concepts in innovation with respect to both individual Premium Content products as well as the Premium Download Manager. If Danger presents a written proposal with respect to new Premium Content opportunities or Premium Content types, T-Mobile will use commercially reasonable efforts to provide a written response to Danger's proposal within a mutually agreed upon time frame targeted to be approximately [ * ] days. Danger and T-Mobile will agree on the appropriate action plan and follow-up (if any) for the management of individual proposals.

C. Editorial & Publishing and Launch Scheduling. Danger will create, maintain, and deliver to T-Mobile on a bi-weekly basis a content publishing report ("Content Publishing Report") which will contain the following information for Applications:

�

Proposed 4-6-week launch schedule for titles that have been approved during the Pipeline Review Process, as well as historical view of weekly launches since last Launched Content Report.

�

For each title: Title, Genre, Short Description, Suggested Retail Price, Networked Application Tier, launch date and revenue share classification.

Danger will not include any content in the Content Publishing Report, unless Danger has the rights to launch the content. T-Mobile will use commercially reasonable efforts to review and provide feedback on the Content Publishing Report within [ * ] business days following receipt

10.

from Danger. T-Mobile will expressly indicate in its feedback to the Content Publishing Report which titles T-Mobile approves for launch along with certain launch dates and the pricing for each approved title. For the avoidance of doubt, titles in the Content Publishing Report are not expressly approved by T-Mobile, unless T-Mobile indicates by marking or initialing its approval. Danger's designation in the Content Publishing Report that a title is "approved" for launch will not be considered T-Mobile approval. Danger will use commercially reasonable efforts to implement T-Mobile's pricing and scheduling changes to the Content Publishing Report within [ * ] days following receipt of T-Mobile's feedback. On a monthly basis during the Term, the parties will meet on-site at T-Mobile or via phone and discuss the publishing and promotion of Applications that have been approved by T-Mobile for launch. The goal of such meetings will be to determine the launch schedule for Applications to be launched within the next [ * ] to [ * ] weeks following the meeting. Provided that T-Mobile complies with the processes outlined in this Amendment and Sections 4A and C of this Appendix, Danger will target launching: (i) [ * ] new Application titles during each calendar quarter of the Term; (ii) [ * ] new Application titles simultaneous with the launch of each new Danger Device, when and if new Danger Devices become available; and (iii) between [ * ] and [ * ] new Background Images and Themes per each calendar quarter of the Term.

D. Editorial Control over Content Availability, Schedule, and Placement. T-Mobile, in its sole discretion, shall have full editorial control with respect to the availability, schedule, and location of all Certain Premium Content in the Premium Download Manager application.

E. Danger's Removal of Premium Content.

(i) Danger Sourced Premium Content. After notice to T-Mobile, Danger may reject or remove any Danger Sourced Premium Content from the Premium Download Manager that, in Danger's reasonable discretion (A) infringes the intellectual property or other rights of a third party, (B) is libelous, defamatory, obscene or pornographic, (C) may violate other civil or criminal laws; including those regulating the use and distribution of content on the Internet and protection of personal privacy, (D) is technically non-functional or inhibits the performance of other applications on the device, or (E) threatens the security or stability of the Danger Services. In addition, Danger may elect not to launch Danger Sourced Premium Content in the event that, in Danger's good faith business judgment, T-Mobile's suggested retail price for such content does not allow Danger to cover its cost plus a reasonable profit margin for such content. Danger will promptly notify T-Mobile if Danger believes that the suggested retail price that T-Mobile plans to adopt does not permit Danger to cover its cost plus a reasonable profit margin for a particular item of content.

(ii) T-Mobile Sourced Premium Content. Danger may reject proposed T-Mobile Sourced Premium Content, or remove from the catalog and suspend the server-side functionality of any T-Mobile Sourced Premium Content from the Premium Download Manager that, in Danger's reasonable discretion, threatens the security or stability of the Danger Service, Danger Device, or Basic Services. Notwithstanding the preceding sentence, prior to removing any T-Mobile Sourced Premium Content, Danger will use commercially reasonable efforts to contact T-Mobile in order to request approval of such removal. For purposes of clarification, each party agrees that Danger's suspension right granted in the preceding sentence is limited to suspending the server-side functionality of T-Mobile Sourced Premium Content. Danger may not under any circumstances remove an application from a Subscriber's Danger Device via Over-the-Air update or otherwise without the prior written approval of T-Mobile. In addition, after notice to and with approval from T-Mobile, Danger may remove any T-Mobile Sourced Premium Content from the Premium Download Manager that, in Danger's reasonable discretion (A) infringes the intellectual property or other rights of a third party, (B) is libelous, defamatory,

11.

obscene or pornographic, (C) may violate other civil or criminal laws;, including those regulating the use and distribution of content on the Internet and protection of personal privacy, or (D) is technically non-functional or inhibits the performance of other applications or services on the device. If T-Mobile disagrees with Danger in regard to the need to remove T-Mobile Sourced Premium Content, then the parties will meet (in person or via telephone) to discuss and mutually agree on whether such content should be removed.

(iii) Nothing in the Agreement or this Amendment (including without limitation any approval of content pursuant to the processes contained herein) shall obligate T-Mobile to include any Premium Content in the Premium Download Manager or Danger's Desktop Interface and Danger will remove Premium Content within a commercially reasonable period of time, which will be no more than [ * ] business [ * ] following notice, if such Premium Content: (A) infringes the intellectual property or other rights of a third party, (B) is libelous, defamatory, obscene or pornographic, (C) may violate other civil or criminal laws, including those regulating the use and distribution of content on the Internet and protection of personal privacy, (D) is technically non-functional or inhibits or impairs the performance of the T-Mobile Network or other applications on the device, (E) causes or results in a higher than average number of calls to or refunds or credits from T-Mobile's customer care, or (F) a third party content provider or government order requires T-Mobile to remove the Premium Content on an expedited basis.

5. Marketing & Promotion:

A. Splash Screens. Danger and T-Mobile will propose promotions for and T-Mobile will approve a Splash Screen publishing schedule reflecting Splash Screen promotion dates and durations in the format provided to T-Mobile (which T-Mobile and Danger may mutually agree to change from time to time) ("Splash Screen Publishing Schedule"). T-Mobile will make its Splash Screen proposals to Danger at the monthly publishing and launch scheduling meeting pursuant to Section 4A of this Appendix or in an email. Danger will create, subject to technical feasibility, all Splash Screens and will design T-Mobile proposed Splash Screens. Danger will design Splash Screens within [ * ] business days following receipt of T-Mobile's proposal. For items designated as rush promotions, Danger will use commercially reasonable efforts to design the Splash Screen in no more than [ * ] business days. At least [ * ] days prior to the monthly publishing and launch scheduling meeting, Danger will provide a proposed Splash Screen Publishing Schedule covering the [ * ] period commencing [ * ] weeks after the meeting as well as a Splash Screen concept document with the actual creative for the Splash Screens on the proposed schedule. Danger agrees that the schedule proposed by Danger will target [ * ] to [ * ] Splash Screen launches per month with a minimum run of [ * ] per each Splash Screen promotion. The parties will periodically evaluate the foregoing frequency and duration targets based upon actual results and may mutually agree to change these targets. T-Mobile will use commercially reasonable efforts to provide feedback on the Splash Screen Publishing Schedule and Splash Screen creative concepts within [ * ] business days following the meeting. If T-Mobile requests revisions to the creative, Danger will revise the creative and resubmit the Splash Screen concept document within [ * ] business days following receipt of T-Mobile's feedback. The parties will continue to work together to revise Splash Screens until they are approved by T-Mobile.

B. Time Sensitive Promotion Alignment. Danger will use best efforts to support T-Mobile's goal of aligning Danger Device promotions with promotions across the T-Mobile device portfolio, particularly with respect to time-sensitive opportunities (e.g., a movie release or a holiday). In order to achieve T-Mobile's goal, the parties will take the following steps:

12.

(i) For Applications that are scheduled to launch on a particular date, T-Mobile will use commercially reasonable efforts to submit the Application proposal to Danger [ * ] days prior to the launch date. Danger will use commercially reasonable efforts to work with the Application developer to mutually agree on a testing and revisions schedule in order to ensure that the Application is certified and ready for launch on the launch date.

(ii) For Splash Screens, T-Mobile will submit Splash Screen proposals to Danger ten (10) business days prior to the desired launch date for the promotional Splash Screen.

(iii) Danger and T-Mobile will work together to develop a timeline for reconfigurations of the promotional folder within the Premium Download Manager when they are requested by T-Mobile. The timeline will be based upon the scope of the proposed reconfiguration.

T-Mobile in the Pipeline Overview Document. Danger will make its proposed ANUPU designation in the Pipeline Overview Document in good faith based upon information obtained by Danger when testing the Application. T-Mobile may audit the ANUPU designation of any Application after it has been launched and if T-Mobile determines that the actual ANUPU for such Application is higher than the designation approved by T-Mobile, the designation will be changed and the revenue share percentage under this Section will be adjusted to reflect actual ANUPU. The foregoing adjustment will be applied on a going forward basis beginning on the first day of the next calendar month, unless T-Mobile determines that Danger's proposed ANUPU designation was not based upon Danger's testing of the Application, in which case the adjustment will be replied retroactively as well. At the time T-Mobile obtains the capability of tracking actual ANUPU, and on a going forward basis, the payments under this Section will be made based upon actual ANUPU; provided that if there is engineering work required for Danger to interface with T-Mobile's ANUPU based billing functionality the parties have reached an agreement regarding such engineering work, and provided further that Danger has at least [ * ] days following T-Mobile's confirmation of its ANUPU billing capability before payments are calculated based upon actual ANUPU.
