 6.2 License Grant to Danger. Subject to the terms and conditions of this Agreement, Sharp grants to Danger, during the term of this Agreement, a
non-exclusive, non-transferable, worldwide, license under Sharp’s Intellectual Property Rights to (i) use, modify and reproduce Sharp Design Technology to design and develop Product reference designs and Danger Software;
(ii) demonstrate Products that include Sharp Design Technology to Approved Carriers and Carrier Customers; (iii) use Products that include Sharp Design Technology for testing, promotional, and development purposes, (iv) use,
demonstrate, sell, offer for sale, distribute (directly to end users or through customers or distributors), and import Products incorporating Sharp Design Technology; and (v) only in the special case described in Section 6.6, make and have
made Products incorporating Sharp Design Technology. 
 6.3 Danger Software Warranty. Danger will warrant to Carrier Customers that
the Danger Software will perform substantially in accordance with the Danger Software specifications for a period of time to be mutually agreed upon between the Carrier Customer and Danger. Danger will have no direct warranty obligation to End

 6.4 Contract Manufacturing Agreement. Danger will have the right to purchase Products from Sharp (i) for
Danger’s use (e.g. for development, testing, marketing, public relations and sales promotion activities) and (ii) in the case Sharp, its Affiliate or its authorized distributor do not sell Products to a wireless operator that wishes to
purchase Products and Danger Services, in which case Danger shall have the right to re-sell to such wireless operator Products purchased from Sharp. The Danger Products will not be sold under the Sharp brand without Sharp’s consent. The Parties
shall use their respective best efforts to execute a separate agreement (the “CM Agreement”) that sets the terms for such supply of Products within ninety (90) days of the date of this Agreement. For Products purchased by Danger in
accordance with this Section 6.4, the price and other terms of sale per unit shall be similar to those provided to Sharp’s North American distributor of the Product; provided however, Sharp may reasonably adjust the prices and other terms
to account for smaller volumes, different delivery terms and Product customizations. Sharp may also adjust the prices and other terms for Products sold to Danger under this Section 6.4 as necessary to avoid breaching its agreement with its
North American distributor. In addition, for Products purchased under this Section 6.4, Sharp shall indemnify Danger for GSM Claims and product liability claims.

third party claim alleging an Intellectual Property Right infringement arising out of the modifications made by the Modifying Party. 
 (b) The Modifying Party shall have no indemnification obligation under this Section 7.5 if the Original Technology alone would have caused an infringement of such third party’s Intellectual Property Rights. 
 8. Branding of Products. 
 8.1 Branding Requirements. The Parties shall mutually agree on the branding for the exterior of each Product. Sharp shall affix or cause to be affixed the Sharp Mark on such Products and on all related
packaging, promotional and advertising materials as mutually agreed to by Sharp and the Carrier. In addition, Sharp shall provide appropriate branding opportunities to Danger, as mutually agreed to by Danger and Sharp, in the marketing and
distribution of any Product. Notwithstanding the foregoing, Sharp shall affix or cause to be affixed the “hiptop® Technology by Danger, Inc.” logo (or other logo designated by
Danger) on all Products distributed hereunder in a location and of a size to be determined by the Parties.

 8.4 Trademark Usage. Except as otherwise expressly stated in this Agreement, each Party agrees
that all uses of the other Party’s trademarks will: (a) include the proper marking for the trademark and the appropriate trademark attribution in reasonably close proximity to its first use of the trademarks; (b) not alter the
trademarks in any way; and (c) use the trademarks so they will not be combined or confused with any other trademark that may be used by the other Party. As between Danger and Sharp, each Party agrees that all uses of the other Party’s
trademarks, including the goodwill and reputation associated therewith, will inure to the benefit of the other Party. Each Party will submit to the other Party a sample of all proposed materials wherein the trademarks of the other Party will be used

 (a) Sharp will notify Danger within five (5) Business Days of
each shipment of Product to wireless carriers. The notification shall include the number of Products shipped and the name of the wireless carrier to whom the Products were shipped. The reason for this reporting is that Danger invoices Carrier
Customers for service fees upon shipment and delivery of Products to the Carrier Customer. 
 (b) Within fifteen (15) Business
Days after the end of each month during the term of this Agreement, Sharp, or, as applicable, its Affiliate or authorized distributor will submit a report in electronic format (MS Excel) to Danger detailing, (a) the number of Products
manufactured by Sharp in the previous month; (b) the number of Products shipped by Sharp during the previous month, on a carrier-by-carrier basis (detailing units by IMEI and by country); (c) non-binding, rolling sales forecasts for the

in violation of Section 6.6(a). In addition, in the event Danger terminates the CM Agreement for Sharp’s material breach, Danger may immediately terminate this Agreement. In the event Danger ceases operations without a successor in
interest, Sharp may continue to manufacture and sell Products to Carrier Customers that are authorized by Danger to operate the Danger Service Software following Danger’s cessation of operations.

 15.1 A Party requesting indemnification (the “Indemnified Party”) shall provide the other Party (the “Indemnifying Party”) with
prompt written notice of any claim for which it seeks indemnification, shall allow the Indemnifying Party sole control of the defense and any settlement of any such claim, and shall reasonably cooperate and provide reasonable assistance to the
Indemnifying Party, at the Indemnifying Party’s expense, in connection with the defense or settlement of any such claim. 
 15.2
Additional Indemnification Rights. The Parties shall work together to prevent manufacturing interruptions due to an allegation of infringement of third party Intellectual Property Rights. In the event of any allegation of infringement of any
third party Intellectual Property Right which is subject to indemnification under this Agreement, the Indemnifying Party shall have the right, in its sole discretion, to (a) obtain a license from the third party; (b) defend against such
allegation through final judgment and all timely filed appeals; and/or (c) redesign the allegedly infringing products in order to avoid infringement. In the event of a redesign as described in (c) above is made available for commercial
use, the Indemnified Party shall use diligent commercial efforts to promptly cease use and distribution of all allegedly infringing products and commence use of the redesigned product, provided that such redesigned product provides substantially
similar functionality and is of substantially similar quality as the allegedly infringing product, but in no event of less quality than the former product. 
 15.3 Limitations. Notwithstanding the foregoing, neither Party shall have any indemnification obligations pursuant to this Agreement with respect to any claim arising from (a) the operation or use of the
such Party’s technology or Intellectual Property Rights with other products, software or materials not furnished by such Party where such Party’s technology or Intellectual Property Rights would not themselves be infringing; or

 16.2 Amendment and Waiver. Except as otherwise expressly provided herein, any provision of this
Agreement may be amended or waived (either generally or in any particular instance and either retroactively or prospectively) only with the written consent of the authorized representatives of both Parties. However, it is the intention of the
Parties that this Agreement be controlling over additional or different terms of any purchase order, confirmation, invoice or similar document, even if accepted in writing by both Parties, and that waivers and amendments of any provision of this
Agreement shall be effective only if made by non-preprinted agreements signed by both Parties and demonstrably understood by its term to be an amendment or waiver of this Agreement. The failure of either Party to enforce its rights under this
Agreement at any time for any period shall not be construed as a waiver of such rights. 
 16.3 Assignment. Neither Party may transfer
or assign this Agreement nor the rights and obligations hereunder (by operation of law or otherwise) without the prior written consent of the other Party. Notwithstanding the foregoing, no consent shall be required for any assignment in connection
with any merger, acquisition, sale or transfer of all, or substantially all of a Party’s stock, assets or business to which this Agreement relates. If Danger ceases operations but transfers or assigns all or substantially all of its assets or
business to a third party successor, Danger will endeavor to have this Agreement assigned to such successor. The terms and conditions of this Agreement shall bind and inure to each Party’s successors and permitted assigns. 
 16.4 Injunctive Relief. Each Party acknowledges and agrees that certain obligations and promises of the Parties set forth in this Agreement are of
a special, unique and extraordinary character. Each Party hereby acknowledges and agrees that a material breach of any of its promises or agreements contained herein involving or relating to the Intellectual Property Rights of the other Party will
result in irreparable and continuing damage to the other Party for which there will be no adequate remedy at law. Accordingly, in the event of any such breach the non-breaching Party shall be entitled to injunctive relief and/or a decree of specific
performance, in addition to such other and further relief as may be proper (including monetary damages if appropriate). 
 16.5 Governing
Law and Legal Actions. In the event Sharp brings a claim against Danger, this Agreement shall be governed by, and construed in accordance with the law of the state of California. In the event Danger brings a claim against Sharp, this Agreement

 2. ORIGINAL
AGREEMENT. The parties agree that the Original Agreement shall be terminated as of the Effective Date but shall survive to govern the parties’ obligations as they arose prior to the Effective Date; provided however, the
parties’ obligations regarding the Danger Software and the Danger Services for Sidekick II Danger Devices shall be governed by the terms and conditions of this Agreement. 
 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. Danger will from time to time solicit product suggestions from T-Mobile as part of this process. Danger will use commercially reasonable efforts to provide bug fixes for the most
recent versions of the Danger Software and the Danger Service as quickly as practicable. Response times for errors with the Danger Service are governed by the SLA and therefore, for any conflict between this Section and the SLA, the terms of the SLA
will prevail. Upgrades or Enhancements to the Danger Software, including updates and upgrades to the Danger operating system, will be made available to T-Mobile at the earliest commercial availability at no additional cost to T-Mobile. All Upgrades
and Enhancements to Danger Software must be tested and accepted in accordance with the procedures set forth in Sections 3.5. Notwithstanding the foregoing, the parties may mutually agree in writing to implement Upgrades and Enhancements without
utilizing such acceptance procedures on a case-by-case basis. 
 3.3 Branding of Services. The Danger Software will be T-Mobile-branded and will
contain no marks (other than T-Mobile Marks) except as mutually agreed, and in any event won’t contain any marks

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-à-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

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 “3rd Party Dependency”). If, through no fault of Danger, material delays result from 3rd Party Dependencies, the parties shall adjust the Roadmap schedules appropriately. Delays that may result from third parties that are not listed as a 3rd 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

will provide T-Mobile with copies of all release notes pertaining to Upgrades and Enhancements of Danger Software. All such testing results, release notes and Danger Software provided to T-Mobile for testing or the T-Mobile Trial Program shall be
treated as Confidential Information. 
 (b) The parties acknowledge that Manufacturers shall be responsible for ensuring that Danger
Devices comply with (i) all required federal, state and local laws, rules, regulations, and codes in existence during the Term (including without limitation, FCC rules, regulations and requirements), as required by T-Mobile, and (ii) all
required Internet standards, EIA/TIA, GSM, GSM NA, and ETSI standards and all other relevant industry specifications and standards, that are required because of the features provided for in the Service Specification. 
 (c) T-Mobile will use commercially reasonable efforts to promptly test each Danger Software Upgrade or Enhancement for compliance with the
applicable Services Specifications, security, PTCRB requirements, market needs, and compatibility with the T-Mobile Network. Danger shall provide T-Mobile with reasonable assistance, including as appropriate, access to Danger’s facilities, to
help T-Mobile conduct testing. 
 (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.

of Danger Service. Throughout the Term, if, for any reason there is any substantial threat that the Danger Service will be interrupted or shut down, or the Danger Service is interrupted or shut down (except in the event of a force majeure event
under Section 23.6), T-Mobile has the right, but not the obligation, to take any and all necessary steps to keep the Danger Service turned on and functional during such period of interruptions or shut down, including the right to access and use
the Source Code (on the Danger premises or within the supervision of Danger personnel), for such limited period of time and strictly for the foregoing purposes, and Danger has an affirmative obligation to allow T-Mobile to take all necessary actions
and shall cooperate fully in all respects with T-Mobile in its efforts to run and maintain the Danger Service at acceptable performance levels for such limited period of time. The parties agree that damages are an inadequate remedy to a breach of
this Section and that T-Mobile may seek specific performance of this Section in the event of a breach by Danger of this Section 4.1(c) where such specific performance shall be enforced solely during the period of time until the Danger Service
is no longer interrupted, shut down, or in imminent danger of being interrupted or shut down. 
 (d) Data Network. T-Mobile
will make commercially reasonable efforts to provide access to wireless data networks in states not in T-Mobile’s footprint where possible through roaming agreements with other wireless carriers. 
 (e) Manager in Residence. T-Mobile has the right, but not the obligation, to have a “manager in residence” located at Danger to
observe Danger’s operations and be a contact point for T-Mobile. T-Mobile will be responsible for all costs associated with this employee’s presence. Any access to Danger’s equipment, or technology is subject to Danger’s
reasonable discretion and may be conditioned upon security, confidentiality, and timing requirements established by Danger. 
 4.2 Customer Support 

 (a) First Tier Support. T-Mobile, at its sole cost, will be responsible for providing, or arranging for the provision of,
initial support services directly to Subscribers (including customer care for the T-Mobile Network; assistance with troubleshooting, set-up, and use of the Danger Services and Danger Software; and billing and account support) with respect to use of
the Danger Services and Danger Software. Danger will not be obligated to provide initial support services (such as trouble shooting and assistance with set-up and use) directly to Subscribers with respect to the Danger Services or the Danger Device.
Danger shall have no obligation to coordinate warranty processing, repair, and refurbishment services for Subscribers’ Danger Devices. 
 (b) Second Tier Support. If T-Mobile personnel experience any problems with the Danger Services or the Danger Devices or if T-Mobile receives questions or complaints from Subscribers regarding the Danger Services or Danger
Devices (including issues relating to troubleshooting, set up, and use of the Danger Services and Danger Devices), Danger, at its sole cost, will provide support to T-Mobile to resolve any problems raised by T-Mobile, including, without limitation,
by following the procedures set forth in the Customer Support SLA attached hereto as Exhibit C. T-Mobile’s customer support representatives that are trained for Danger Device support shall interact with and escalate issues

to Danger’s customer support team. Except as set forth in Section 4.2(a) above, or pursuant to the Customer Support SLA, Danger will not be
obligated to provide support directly to Subscribers with respect to the Danger Services or the Danger Device; however, Danger may, at its option, upon the request of T-Mobile, have a Danger support person interact directly with a Subscriber when
the Danger support manager deems it is the most effective manner to resolve a problem relating to the Danger Services or the Danger Device. 
 (c) Escalation. 
 (i) Danger will communicate incident resolution progress to T-Mobile and escalate its
problem resolution efforts within the time limits specified in the SLA. In addition to the contacts set forth in the SLA, Danger will provide T-Mobile with a primary contact for all technical and service related issues that arise in connection with
the Danger Services or Devices; provided, however, that T-Mobile may contact any other appropriate Danger personnel if T-Mobile so chooses. 
 (ii) Upon T-Mobile’s request, Danger shall make available within ten (10) business days, at T-Mobile’s offices, during normal business hours, the Danger program manager and other appropriate personnel to discuss the
status of the Danger Services, the Danger Software and Danger’s compliance with this Agreement. 
 (d) Support
Information. The parties shall work together to exchange information about customer support issues on a regular basis, at least once per calendar month. Danger shall provide T-Mobile with the Danger Support Tool to allow the T-Mobile’s
customer support to access subscriber information stored in the Danger data center and file trouble tickets with Danger. T-Mobile will authorize the disclosure of RMA and Danger Device return information by Manufacturers to Danger. 
 (e) Customer Service Training. As mutually agreed upon by the parties, Danger will provide periodic “train-the-trainer” sessions
for T-Mobile training personnel to enable such personnel to train T-Mobile’s customer care staff to provide first tier support for the Danger Services and Danger Devices. With T-Mobile’s prior permission, Danger customer care
representatives may visit T-Mobile’s customer call center to offer guidance, training and observe T-Mobile’s customer care for the Danger Service and Danger Devices. 
 4.3 Danger Service Reporting. 
 (a) Danger Reporting to T-Mobile. Danger shall provide
to T-Mobile written notice immediately upon the occurrence of the following events: (i) any manufacturing defect in the Danger Devices of which Danger is aware, (ii) any high severity bug or defect in the Danger Services or Danger Software
of which Danger is aware, (iii) any legal action or threatened legal action involving the Danger Software, Danger Service, or Danger Device (of which Danger is aware) (iv) any breach or default of any material term in this Agreement,
(v) Danger’s breach, or threatened breach of a material third party agreement related to the Danger Software or Danger Services, (vi) Danger’s inability to pay any invoices or money owed when such money is due, or (vii) any
security breach or material loss of Subscriber Information. 
 (b) Service Reporting. Throughout the Term, on a monthly basis,
Danger shall provide to T-Mobile within ten (10) business days of the end of the month, aggregate Subscriber usage information, and active days per Subscriber, in a form and substance to be mutually agreed upon by the parties, but in no event
may Danger refuse to provide information that is readily available in Danger’s usual course of business. In addition, as part of the standard Roadmap process, Danger will work with T-

Mobile to prioritize and schedule the development of enhanced reporting capabilities that are requested by T-Mobile. 
 (c) T-Mobile Reporting to Danger. 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

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

 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.

 9.6 Regional Operators. Notwithstanding Sections 9.1 through 9.5,
Danger may distribute without restriction any [ * ] and any [ * ] to any [ * ]. 
 9.7 [ * ] Provisions. Except as
expressly set forth in [ * ], or otherwise expressly set forth in this Agreement, each party acknowledges and agrees that the rights granted to and obligations due to the other party in this Agreement are [ * ], and that, without
limiting the generality of the foregoing, nothing in this Agreement shall be deemed or construed to prohibit either party from participating with one or more third parties in business arrangements similar to or competitive with those described

released. If such Danger Devices or Danger Services use the T-Mobile Network, then the users of such devices or service must be paying Subscribers unless otherwise agreed upon by the parties. 
 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

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.

 (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 (10th) 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.

 (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.

 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

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. If [ * ] such products or services, Danger will immediately notify T-Mobile and will [ * ] hereunder, and provide such
products or services [ * ]. The [ * ] charges and fees incurred as of the date [ * ] and to any products ordered by T-Mobile or scheduled to be delivered to T-Mobile as of the date [ * ] subject to this Section. Danger

 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 [ * ].

“Danger Technology”). 
 12.4 T-Mobile Ownership. T-Mobile and its licensors retain all rights, title and interest in and to
the T-Mobile technology and T-Mobile Premium Content owned by T-Mobile (except for any Danger Technology that may be contained in such T-Mobile Premium Content). 
 12.5 License to Danger. Subject to the restrictions of Section 14.2, T-Mobile hereby grants Danger a limited, non-exclusive, and non-transferable (except in connection with 21.1) license to use and copy Aggregate Information
solely for those purposes stated in Section 14.2(d). 
 12.6 Mutual License Grant of Trademarks. Subject to all the terms and conditions of this
Agreement, each party (“Licensor”) hereby grants the other party (“Licensee”) a nonexclusive, non-transferable, non-sublicensable license to use the Licensor Marks solely as
identified in, and in the manner described in, Exhibit H. “Licensor Marks” means solely the names, trademarks, service marks and logos as provided by Licensor in writing specifically for use under this Agreement. However, Licensor,
in its sole discretion from time to time, may upon written notice change the appearance and/or style of any Licensor Mark or add or subtract from the Marks previously supplied. Unless required earlier by a court order or to avoid potential
infringement liability, Licensee will have a reasonable period of time to implement any such changes and if Licensor requires any changes to materials that have already been produced, the Licensor will pay the Licensee for any costs involved in such
change. Licensee hereby acknowledges and agrees that (i) the Licensor Marks are owned solely and exclusively by Licensor or its affiliates, (ii) except as set forth herein, the Licensee has no rights, title or interest in or to the
Licensor Marks and (iii) all use of the Licensor Marks by Licensee will inure to the benefit of Licensor and its affiliates. Licensee agrees not to apply for registration of the Licensor Marks (or any mark confusingly similar thereto) anywhere
in the world. Licensee agrees that it will not engage, participate or otherwise become involved in any activity or course of action that diminishes and/or tarnishes the image and/or reputation of Licensor or of any Licensor Mark. Licensee
acknowledges and agrees that the presentation and image of Licensor’s Marks should be uniform and consistent with respect to all services, activities and products associated with the Licensor’s Marks. 
 12.7 Trademark Use and Brand Confusion. Danger agrees to refrain from describing Danger Devices branded “T-Mobile Sidekick” as “hiptops” in
the consumer press and consumer messaging. For instance, when describing a celebrity who endorses or uses a device branded “T-Mobile Sidekick,”

Danger shall not make statements in consumer magazines or the popular press that such celebrity uses a “hiptop” device. 
 13. ESCROW 
 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”). All subsequent major version upgrades,
enhancement and documentation or bug fixes for the Danger Service will also be deposited with the Escrow Agent after acceptance by T-Mobile. The Escrowed Code shall include the source code for software licensed by Danger from third parties only to
the extent Danger has the rights to do so. For third party software that Danger does not have rights to escrow in source code form, Danger shall use reasonable efforts to obtain the right to deposit object code of such third party software for
release to T-Mobile in conjunction with an escrow release hereunder. 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; 

(c) Danger has [ * ] catastrophic Danger Service Outages (as defined in the SLA) in any calendar year, except due to a force majeure
event under Section 23.6; 
 (d) [ * ]. 
 13.3 License; Ownership.

Danger hereby grants and agrees to grant to T-Mobile a non-exclusive, non-transferable (except pursuant to Section 21.1) perpetual license to use, copy, and create derivative works of the Escrowed Code following the occurrence of any Release
Condition, solely for the purposes specified in Section 13.2 (i.e., T-Mobile’s separate implementation of the Danger Service) and solely within the scope of this Agreement. 
 (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. T-Mobile will be the exclusive owner of any modifications to or derivative works of the Escrowed Code created by or for T-Mobile under this

 13.4 Manufacturers. Danger shall provide each Manufacturer of Danger Devices (excluding authorized distributors) the right to obtain the Source Code for the Danger Software under escrow terms, release conditions, and license
terms that are substantially similar to those provided to T-Mobile for the Danger Service Source Code hereunder. 
 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

separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended.

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;

 (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

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;

 (d) The Danger Services and the Danger Software (excluding T-Mobile Premium Content) do not and will not constitute a misappropriation or
infringement of any Intellectual Property rights of any third party.

 (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. ALL SUCH WARRANTIES ARE HEREBY EXPRESSLY DISCLAIMED. EXCEPT AS EXPRESSLY PROVIDED OTHERWISE

 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

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. 
 17.6 Notwithstanding anything in this Agreement, in no event will Danger be required to
indemnify or compensate T-Mobile or any Indemnified Party for liabilities for which T-Mobile or any Indemnified Party has received full indemnification or compensation from a Manufacturer.

 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. If (i) or
(ii) are undertaken by Danger, then the foregoing states Danger’s entire liability and T-Mobile’s exclusive remedy for Danger’s breach of its warranty of Section 15.2(d). If (i) or (ii) are not available despite
Danger’s commercially reasonable efforts, then T-Mobile will have the right to terminate this Agreement and T-Mobile may exercise any of its rights and remedies as set forth in this Agreement, at law or in equity. Nothing in this Section is to
be interpreted to waive any of T-Mobile’s rights or Danger’s obligations under T-Mobile’s right to indemnification resulting from third party claims. 
 19. INSURANCE REQUIREMENTS 
 19.1 At its sole expense, Danger shall carry and
maintain throughout the term of this Agreement all insurance described below. All deductibles and premiums are the responsibility of Danger. The policies described below shall be primary and not contributory with any coverage maintained by T-Mobile.
The policies shall include T-Mobile USA, Inc. as an additional insured, but T-Mobile will not be included as an additional insured for its own negligence. The policies shall contain a severability of interests provision. The form of the insurance
shall at all times be subject to T-Mobile’s reasonable approval, and the carrier or carriers must have an A.M. Best rating of A-, VIII or higher. The liability policies must each contain a provision by which the insurer agrees that such policy
shall not be canceled except after thirty (30) days written notice to T-Mobile. 
 19.2 Danger shall maintain the following lines of coverage
pursuant to this Section 19: Danger will carry Commercial General Liability (Occurrence Form) with a minimum combined single limit for bodily injury and property damage of [ * ] per occurrence, including coverage for personal/
advertising injury and contractual liability. The above coverage may be provided by any combination of primary or excess insurance policies in Danger’s reasonable discretion. 
 20. TERM AND TERMINATION 
 20.1 Term. This Agreement is effective
as of the Effective Date, and will continue in effect until December 31, 2008, unless terminated earlier as provided in Section 20.3 below (the “Initial Term”). For purposes of this Agreement the “Term” will consist of
the Initial Term and the Renewal Term (if any) (as set forth in Section 20.2) (collectively the “Term”). 
 20.2 Renewal. Unless
either party gives the other written notice of its intent not to renew this Agreement at lease one hundred eighty (180) days prior to the end of the Initial Term, T-Mobile has the right to renew this Agreement for a single additional

 (a) Immediate Termination. T-Mobile may terminate this Agreement immediately upon notice to Danger if Danger is in breach of Section 14.2(b) or (c) of this Agreement. 
 (b) Termination for Breach. 
 (i)
Either party may terminate this Agreement upon not less than thirty (30) days prior written notice to the other of any material breach of the terms of this Agreement (including, without limitation, the Service Level Agreement), provided
that such other party has not cured such material breach within such thirty (30) day notice period. 
 (ii) Notwithstanding the
above, in the event that Danger and T-Mobile have bona fide dispute regarding the proper billing or payment for Danger Services, Danger may not terminate or suspend performance of this Agreement until the parties have completed the required
expedited arbitration procedure, as set forth in Section 23.3. 
 (c) Effect of Termination. Upon any termination or expiration
of the Term for any reason, all rights and obligations of the parties under this Agreement shall be extinguished, except that: (a) all accrued payment obligations hereunder shall survive such termination or expiration; and (b) the rights
and obligations of the parties under Section 20.4 shall survive in accordance with their terms. If prior to any termination or expiration of this Agreement, a Release Condition has occurred under Section 13.2, and T-Mobile has asserted its
rights to the Software, Section 13 shall also survive. Upon any termination or expiration of this Agreement, except for non-payment of undisputed amounts, Danger will provide T-Mobile with transition support to facilitate the orderly completion
of the Danger Services and the transition of Subscribers to T-Mobile or any third party service provider designated by T-Mobile, including, without limitation by providing T-Mobile with any and all Subscriber Data or other necessary information. If
termination of this Agreement is due to a breach by T-Mobile or by expiration, then all such transition costs will be at T-Mobile’s expense. If termination of this Agreement is the result of Danger’s breach, then such transition costs will
be at Danger’s expense. 
 20.4 Survival. Any rights to accrued payments, any right of action for breach of the Agreement prior to termination,
and the following sections survive any termination or expiration of this Agreement: 1, 2, 10.5, 10.6, 10.7, 10.8, 10.9, 12.2, 12.3, 12.4, 13.3, 14.1, 14.2, 14.3, 14.5, 14.6, 15.5, 16, 17, 18, 20.3(c), 20.4 and 23. 
 21. CHANGE OF CONTROL; ASSIGNMENT. 
 21.1 Change of Control. Danger will provide T-Mobile with a right of first refusal on the sale of a controlling interest of Danger to a US Operator on substantially similar terms and conditions, including
equivalent pricing and timing as that of the competitive offer. This right ends upon the successful completion of an initial public offering of Danger stock. In the event a controlling interest in Danger is acquired by a US Operator, Danger and its
successor(s) must continue to provide the Danger Service in accordance with the terms and conditions of this Agreement. 
 21.2 Assignment. Danger may
not assign its rights nor delegate its obligations under this Agreement without the prior written consent of T-Mobile, which such consent may not be unreasonably withheld or denied. However, the assignment of this Agreement to a US Operator shall
require T-Mobile’s prior written consent and T-Mobile has the right to deny consent for any or no reason, provided that such written denial of consent is received by Danger within fifteen (15) days of the request for consent. Any attempted
assignment or delegation not in accordance with this Section will be void and of no force or effect. T-Mobile may assign this Agreement to any T-Mobile-Related Company, provided that T-Mobile

those arising from merger, consolidation, sale of assets or otherwise, if not otherwise prohibited by this Agreement.

the services provided by T-Mobile hereunder except as expressly directed in writing and in advance by T-Mobile. The Parties will act solely as independent contractors to each other in performing this Agreement, and nothing herein will be construed

 23.2 Governing Law; Venue. This Agreement and the rights and obligations of the Parties hereunder are to be construed and enforced in accordance with and governed by the laws of the State of Washington, without regard to conflict of
law or choice of law principles and notwithstanding the location of Danger’s manufacturing or other facilities, the Delivery Location, or the location of the Parties. Danger and T-Mobile hereby submit to exclusive venue, and personal and
subject matter jurisdiction of any state or federal court sitting in King County, Washington. 
 23.3 Expedited Arbitration. The parties will act in
good faith and use commercially reasonable efforts to promptly resolve any bona fide disputes under this Agreement (each a “Dispute”) between the parties or any of their respective subsidiaries, affiliates, successors or
assigns under or related to this Agreement. Except for claims for injunctive relief, or any breach of Sections 12.2, 12.3, 12.4, 12.5, 12.6, 13.3 or 14, such Disputes will be governed exclusively and finally by expedited arbitration. Such
arbitration will be conducted by the American Arbitration Association (“AAA”) in Seattle, Washington, will be initiated and conducted in accordance with the Commercial Arbitration Rules of the AAA, as such rules are in effect
on the date of delivery of a demand for arbitration, except to the extent that such rules are inconsistent with the provisions set forth herein, and such expedited arbitration shall be concluded within sixty (60) days of the demand for
arbitration. The arbitrator will have the non-exclusive power to issue an injunction or require specific performance as he or she finds necessary. The arbitrator must have significant experience in commercial litigation and the technology and
telecommunications industries. Each party will use its best efforts to expedite selection of an arbitrator and will reply to any request to select an arbitrator within five (5) days. Should arbitration result in a monetary award to either
party, the party owing the award shall have ten (10) days to pay such an award, or the other party may thereafter terminate this Agreement immediately for failure to provide payment of the arbitration award. 
 23.4 Interpretation. The headings, subheadings, and other captions in this Agreement are for convenience and reference only and will not be used in interpreting,
construing, or enforcing any of the terms of this Agreement. Each party acknowledges that it has had the opportunity to review this Agreement with legal counsel of its choice, and there will be no presumption that ambiguities will be construed or
interpreted against the drafter, and no presumptions made or inferences drawn because of the inclusion of a term not contained in a prior draft or the deletion of a term contained in a prior draft. 
 23.5 Attorneys’ Fees. If any Party to this Agreement commences litigation to enforce or construe any provision of this Agreement, the prevailing party is, in
addition to other remedies, entitled to recover its reasonable attorneys’ fees and costs in such litigation and any appeal therefrom. 
 23.6 Force
Majeure. Neither party will be in default of or have breached any provision of this Agreement as a result of any delay, failure in performance or interruption of service, resulting directly or indirectly from third party labor disputes, the
bankruptcy of third parties, acts of God, including earthquakes, acts of war, terrorism, lightning, or fire, and also including any disruption or unavailability of communications, utility, or Internet services caused by such acts of God. In the
event of such a force majeure event that continues for at least [ * ], then either party may terminate this Agreement upon written notice to the other party. 
 23.7 Waiver. Any waiver by either Party of any breach of a term or provision of this Agreement must be in writing and will not be construed as a waiver of any subsequent breach of such term or provision or of
any other term or provision. No delay or omission in the exercise of any power, remedy or right herein provided or otherwise available to a Party will impair or affect the right of such Party thereafter to exercise the same. Any extension of time or
other indulgence granted to another Party hereunder does not otherwise alter or affect any power, remedy or right of any other Party; or the obligations of the Party to whom such extension or indulgence is granted.

 23.8 Severability. In the event any provision of this Agreement shall for any reason be held to be invalid, illegal or unenforceable in any respect, the remaining provisions shall remain in full force and effect. If any provision of
this Agreement shall, for any reason, be determined by a court of competent jurisdiction to be excessively broad or unreasonable as to scope or subject, such provision shall be enforced to the extent necessary to be reasonable under the
circumstances and consistent with applicable law while reflecting as closely as possible the intent of the parties as expressed herein. 
 23.9 Entire
Agreement. This Agreement together with the Exhibits attached hereto, including, the Device Supply Terms and Conditions, Service Level Agreement, and Escrow Agreement contains the entire understanding of the parties with respect to the

 EXHIBIT B: SERVICE LEVEL AGREEMENT 
 This Exhibit

 1. Definitions. 
 1.1 “Outage” means a service interruption that affects a majority of users
utilizing that service at the time of occurrence. Service interruptions occurring during Scheduled Maintenance Windows or caused by a failure of a T-Mobile system or service are not Outages and will not be counted in the calculation of Service

 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.

 (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 [ * ]. 
 6.9 System Architecture Design. 
 (a)
Chief Architect. Within ninety (90) days of signing this Agreement, Danger will hire a Chief Architect who will be responsible for the design and scalability of the Danger Services. 
 (b) Third Party Consultant – System Architecture. Danger will, at its cost, identify and hire a third party consultant(s) that will
(i) review Danger’s existing network infrastructure, (ii) evaluate issues regarding the scalability, stress-testing, service level diagnostics, disaster recovery, and security of the infrastructure, and (iii) provide
recommendations regarding modifications or additions to the infrastructure to improve any of the foregoing issues (the “System Architecture Review”). 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. Such report shall be subject to a confidentiality agreement provided by Danger, similar to the
Security Information Confidentiality Agreement between dated July 1, 2005, but T-Mobile may identify different individuals at T-Mobile that may review the report other than those contained in the Security Information Confidentiality Agreement.

 (c) Implementation of System Architecture Design. Danger will complete a system architecture revision plan by July 14, 2006
aimed at supporting [ * ] T-Mobile Subscribers by January 1, 2007 and [ * ] T-Mobile Subscribers by January 1, 2008. The parties shall meet for a joint architectural and capacity review before July 31, 2006, and hold
periodic reviews twice per calendar year thereafter (more frequently if necessary). Such reviews would include T-Mobile systems and capacity planning information. Danger’s architecture plan and reviews shall be subject to the confidentiality
agreement described in 6.9(b) above. 
 6.10 Enhanced Monitoring and Reporting. Within 16 months of the date of signing this Agreement, Danger
will have substantially implemented, in the full production environment, and in a manner that has been accepted by T-Mobile (such acceptance not to be unreasonably withheld), the service level diagnostics and reporting guided by the minimum
requirements set forth in Schedule 1 hereto (“Monitoring Enhancements”). At all times, Danger will keep T-Mobile informed about the Monitoring

Enhancements and the schedule of implementations made by Danger. If Danger has not implemented the Monitoring Enhancements within 16 months of the signing of
this Agreement, then the monthly Service Fees will be reduced $[ * ] per subscriber until such Monitoring Enhancements are implemented. 
 6.11
No Double Dipping. For any given series of events (e.g., Degradation or Outages), during a calendar month, T-Mobile may only choose to invoke Service Fee credits for one of the following issues: (i) Danger Service Outages under
Section 5.2; (ii) Application Degradations under Sections 6.2, 6.3 and/or 6.4; or (iii) Application Severe Degradation under Section 6.6, but in no event will the Service Fee credits exceed the monthly service fees for that
month. 
 7. Interconnection for Data 
 7.1
Equipment. Danger will provide physical servers, switches, routers, and other equipment and infrastructure suitable to host and support the services required in this Agreement. 
 7.2 Network Connectivity and Service Levels. Danger is responsible for network connectivity from T-Mobile’s [ * ] and such other points of
interconnection to each Danger data center including IP backbone carriers. Such network connectivity shall encompass fully redundant and diverse dedicated connections to the Internet, each with minimum bandwidth capacity of [ * ] burstable up
to [ * ]; provided, that when such dedicated connections reach [ * ]% of capacity, then Danger shall arrange to upgrade capacity in order to alleviate such condition. The parties acknowledge that T-Mobile’s cooperation is required
to add capacity and/or to facilitate repairs in a timely manner so that network connectivity capacity may be maintained in accordance with this Section 7. Therefore, Danger shall not be liable for the credits set forth herein, if T-Mobile fails
to cooperate or delays its assistance for Danger to properly manage network connectivity capacity. 
 7.3 Credits: In the event usage via
dedicated connections to the network reaches a daily average of between [ * ]% - [ * ]% of network connectivity capacity for [ * ], T-Mobile will be entitled to receive prospective credits equal to [ * ]% of the Service
Fees paid by T-Mobile for the applicable period. In the event usage via dedicated connections to the network reaches a daily average of between [ * ]% - [ * ]% of network connectivity capacity for [ * ], T-Mobile will be
entitled to receive credits equal to [ * ]% of the Service Fees paid by T-Mobile for the applicable period. In the event usage via dedicated connections to the network reaches a daily average of between [ * ]% - and [ * ]% of
network connectivity capacity for [ * ], T-Mobile will be entitled to receive credits equal to [ * ]% of the Service Fees paid by T-Mobile for the applicable period. In the event usage via dedicated connections to the network exceeds a
daily average of [ * ]% of network connectivity capacity for [ * ], T-Mobile will be entitled to receive credits equal to [ * ]% of the Service Fees paid by T-Mobile for the applicable period. The parties acknowledge and agree
that the damages that T-Mobile will incur in the event Danger fails to monitor and expand network connectivity capacity as may be required from time to time are extremely difficult to calculate, that the credits described herein are a reasonable
estimate of T-Mobile’s damages in such event, and that the credits described herein are in addition to any other damages or refunds that may become due and owing under the terms of this Exhibit B. T-Mobile shall be permitted to withhold
payments in the amounts equal to the credits due under this Section 7.3 from amounts owed to Danger for Service Fees. Danger shall issue credit memos for credits earned under this Section 7.3 to T-Mobile within ten (10) business days
from the end of each calendar month in which a credit was earned. 
 7.4 Maintenance and Upgrade of Danger’s Network. If any maintenance
needs to be performed on Danger’s network, it will be scheduled and coordinated with T-Mobile. Danger will notify T-Mobile via e-mail of scheduled Outages not less than 72 hours in advance. If an Outage is to be more than two (2) hours in
duration, then T-Mobile will be notified at least five (5) business days in advance. Danger will

 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.

 i) Email – reports will include (for @tmail): total number sent; total number received; percentage pass/fail delivery rates; total number of successful delivery; total number of failed delivery;
average round-trip performance of customer email from the entry point of the Danger Service, through the Service, and back to the entry point; and number of subs at 90% mail storage capacity. 
 ii) Web Proxy – reports will include: total web pages requested; total web pages received; percentage pass/fail download within [ *
]; total number of successful download; total number of failed download; and performance of top 10 popular sites. 
 iii) Instant
Messaging – reports will include: percentage pass/fail delivery rates based on failure type; number of subscribers involuntarily terminated. Danger will use reasonable efforts to develop reporting as described in this Section
(1)(a)(iv), but if it is unable to, Danger shall use reasonable efforts to develop (within the 16 month timeframe) a suitable alternative that is reasonably acceptable to T-Mobile. 
 d. Additional Enhanced Reporting – Danger shall use reasonable efforts to scope the following additional requests of T-Mobile:

 i) KPI Tool – Performance measurement for email for non-@tmail account types; other tests and more specific
tests. 
 ii) E-Mail – reporting on customer data for sent or received emails to non-@tmail accounts, including volumes by
email provider and SMTP failure information.

 b. Content Availability, Schedule, and Placement. Subject to the provisions in this Section, T-Mobile, in
its sole discretion, shall have full editorial control with respect to the [ * ] from the release of such Content. If Danger does not have the necessary rights for the proposed Danger Premium Content to be distributed for a minimum of [ *
], then prior to T-Mobile’s consideration and approval of such Content, Danger will provide notice to T-Mobile, in the manner set forth in Section 1(e), of the length of time that such Content may be distributed. 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. T-Mobile’s right and Danger’s obligation to take down the Intellisync Software under the preceding sentence shall be subject to the limitations set forth in Section 3(c). 
 c. Removal of Premium Content. 
 (i) Danger Premium Content. After notice to T-Mobile, Danger may reject proposed Danger Premium Content, or remove any Approved Danger 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 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.

 (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. 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 Approved T-Mobile 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 Approved T-Mobile 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, 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 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 Sections 3(b) and 11) shall obligate T-Mobile to include any Premium Content (including without limitation the Intellisync Software) in the Premium Download Manager or

 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. 
  

 [ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed
separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

 “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. 
  

 [ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed
separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

 (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), 

  

 [ * ] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed
separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

 
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.

systems that host the Danger MySpace Service and MySpace’s systems that host the MySpace Service. If T-Mobile receives updated MySpace API documentation that Danger does not receive, T-Mobile may provide such documentation to Danger and such
API documentation shall be considered confidential information subject to Section 14.1 of the Agreement and used only to maintain interoperability for the SK Application and the Danger MySpace Service. 
 B. T-Mobile. T-Mobile warrants that it has entered into a separate agreement with MySpace and obtained the rights for Danger and T-Mobile to permit

 C. No Warranties for the MySpace Service. Neither party makes any
representation or warranty to the other regarding the MySpace Service and neither party shall have any obligation to indemnify the other for issues arising out of the MySpace Service, including but not limited to the content or material posted on or

 V. Acceptance of SK Application. T-Mobile hereby accepts SK Application v1.0 for the Sidekick 2, the Sidekick 3 and the Sidekick ID Danger Devices. Prior to the
commercial launch of the SK Application on any additional Danger Devices, the following schedule for acceptance and correction of any problems with the SK Application shall be used (unless agreed otherwise by the parties): T-Mobile shall have thirty

forth in Appendix A; Danger’s written guarantees, representations, and warranties; applicable regulatory rules and other federal state, and local legal requirements; or the Content Certification Plan. If T-Mobile rejects a deliverable or any
portion thereof, Danger will correct it within a mutually agreeable time period (that will not exceed thirty (30) days). If Danger fails to correct any errors in a SK Application within a time period mutually agreed to by the parties (not to
exceed thirty (30) days), T-Mobile may (a) accept the non-conforming SK Application deliverable and continue under this Amendment (without waiving its rights to reject other SK Application deliverables); (b) extend the correction
period; or (c) reject the non-confirming SK Application. Notwithstanding the foregoing, T-Mobile’s commercial launch of the SK Application on any Danger Device shall constitute its acceptance of the SK Application for such Danger Device.

schedule for acceptance and correction of problems prior to such distribution. Notwithstanding the foregoing, T-Mobile shall be under no obligation to launch

connect Danger’s servers with the servers of MySpace in order to provide the Danger MySpace Service. 
 B. Deployment
Plans. Danger and T-Mobile will mutually agree upon the timing for deploying the SK Application to each of the Initial Device models. The parties will work together and with MySpace (as necessary) to manage a successful deployment of the SK

 A. Requirements. Danger agrees that the SK Application and the Danger MySpace Services will comply with the specifications set forth in Appendix A, including the Danger MySpace Service’s

Premium Content, as set forth in the Agreement. 
 B. Service Level Agreements. For issues related to the SK Application or the
Danger MySpace Service, Danger and T-Mobile will follow the Escalation Procedure set forth in Section 2 of the Service Level Agreement described in Exhibit B to the Agreement. Danger warrants to T-Mobile that Danger has an incident management

modifications to the SK Application will be subject to acceptance testing by T-Mobile in accordance with Section V, above. In no event will Company modify the Danger MySpace Services or SK Application to enable the distribution of applications or
audio or visual content (including but not limited to ring tones and wallpaper) to Subscribers. Notwithstanding the foregoing, Danger may, without T-Mobile’s prior written approval, distribute bug fixes for the SK Application and implement
changes to the Danger MySpace Service that do not materially change the functionality of the SK Application. Any bug fix or change that affects the user experience is a material change. 
 E. User Agreement: Danger will, within the download process for the SK Application require Subscribers to agree that downloading the SK

 H.
Advertising. Danger will not include any advertisement or promotions in the SK Application or cause any advertisements or promotions to display prior to the download, installation or execution of the SK Application. T-Mobile acknowledges
that Danger has no control and is not responsible for advertisements or promotions that appear in the content and material transmitted to and from the MySpace Service.

routine, trap door, time bomb; or (c) any other code or instruction that is intended to be used to access, modify, delete, damage, or disable the functionality of the MySpace Service. Danger will promptly notify MySpace and T-Mobile if it knows
of any Harmful Code that has entered the MySpace Service through Danger’s connection to MySpace and remedy such incident in accordance with the incident management process agreed upon between Danger and MySpace. 
 VII. Licenses. 
 A. Application
License. Subject to the terms and conditions of this Amendment, Danger grants to T-Mobile a limited, non-exclusive (except as set forth in Section VII(B) below), fee-bearing, license for T-Mobile to (a) use, publicly display and

Application on Initial Devices. 
 B. Source Escrow. Pursuant to Section 13 of the Agreement, Danger shall place into

Agreement. Subject to the written consent and any conditions imposed by MySpace, for the purposes of Section 13.4 of the Agreement, the SK Application will be considered Danger Software. 
 C. [ * ]. Subject to the terms and conditions of this Amendment, [ * ].

set forth in the preceding sentence, this Amendment will have the same Term as the Agreement and will terminate when the Agreement terminates. 
 F. Survival. The parties acknowledge and agree that copies of the SK Application sold or licensed to Subscribers prior to the expiation or
termination of this Agreement survive such termination or expiration and the SK Application will not be removed from Danger Devices even if the Danger MySpace Service is no longer being provided. The pricing and fees set forth in Exhibit B shall
survive the term of the Agreement for the Initial Devices and any other Danger Devices for which the parties agreed (during the term of this Amendment) to distribute the SK Application v1.0. For the avoidance of doubt regarding the preceding
sentence, if the Agreement terminates and the parties enter into another agreement for the supply of the Danger Services to T-Mobile, the SK Application will be provided to T-Mobile for the Initial Devices and any other Danger Devices for which the
parties agree (during the term of this Amendment) to distribute the SK Application v1.0 on the same financial terms and the amounts paid under this Agreement shall be applied to such new agreement as applicable (e.g., if T-Mobile has paid $[ *
] in License Fees, T-Mobile shall only be required to pay an additional $[ * ] in License Fees pursuant to Section 2 of Exhibit B). 
 G. Payment. Fees for MySpace Services and the SK Application and reporting and billing administration for SK Applications are set forth in Appendix B to the Amendment. 
 VIII. Entire Amendment. This Amendment and the Agreement constitute the entire agreement between the parties with respect to the subject matter hereof and merge
all prior and contemporaneous communications. They shall not be further modified except by a written agreement dated subsequent to the Amendment Effective Date and signed on behalf of T-Mobile and Danger. 
 IN WITNESS WHEREOF, the parties have entered into this Amendment as later of the two dates below.

 3. Pricing Change. The parties anticipate the fees in Section 2 above to apply at the commercial
launch of the SK Application if [ * ] the MySpace Service via the SK Application. This Section 3 is intended to apply if T-Mobile [ * ] the MySpace Service via the SK Application upon commercial launch or in the event T-Mobile
[ * ] sometime after commercial launch of the SK Application. If T-Mobile [ * ] the SK Application [ * ] the MySpace Service, then Danger shall have the option to [ * ] the SK Application to access the MySpace Service. If
for any period of time T-Mobile does not [ * ] the MySpace Service and then [ * ] the MySpace Service, T-Mobile shall provide Danger with at least forty-five (45) days’ written notice prior to such pricing change. Following

and non-refundable regardless of the [ * ]. Notwithstanding the foregoing, if T-Mobile has paid Danger [ * ] Dollars ($[ * ]) under
Section 2 and T-Mobile subsequently [ * ] the SK Application to access the MySpace Service, then the [ * ] (i.e. Danger will [ * ]). In addition, if T-Mobile switches its pricing model for the MySpace Service [ * ],
then at the time of such changes the fees under Section 2 shall apply instead of the [ * ] under this Section 3 and all amounts already paid under this Section 3 will be applied. For example if T-Mobile has already paid Danger
[ * ] Dollars ($[ * ]) under this Section 3, then T-Mobile will only be required to pay an additional [ * ] Dollars ($[ * ]) in License Fees under Section 2. If T-Mobile chooses a pricing model for the SK
Application and/or MySpace Service other than [ * ], then the parties shall mutually agree on the economics of such arrangement prior to T-Mobile’s change to such alternative pricing model. If Danger elects to receive fees under this
Section 3, the parties will agree to additional service level metrics (e.g,. uptime, etc.) for the SK Application as well as remedies that will apply in the event the SK Application or Danger MySpace Service are unavailable or are not
functioning properly. 
 4. Prepayment. Danger will invoice T-Mobile for a non-refundable $[ * ] prepayment of the License Fees following the
execution of this Amendment. This prepayment will be applied against the amounts due in the table above. 
 5. Payment Terms. T-Mobile will pay
License Fees due per the table above within thirty (30) days of receipt of Danger’s invoice. 
 6. New Versions. If the parties mutually
agree upon and Danger develops and licenses to T-Mobile a new version of the SK Application (e.g., version 2.0), then the parties will mutually agree upon additional payments for such new version or Danger Device. If the parties mutually agree to
distribute Version 1.0 of the SK Application to Danger Devices other than the Initial Devices, the economics set forth in Sections 2 and 3 of this Agreement shall apply. If the porting of the SK Application to a new Danger Device requires
development efforts by Danger that are significantly greater than porting of the SK Application from the Sidekick ID to the Sidekick 3, then the parties will mutually agree upon a reasonable porting fee to compensate Danger for the additional
efforts required to port the SK Application to such Danger Device.

in active QA; Applications currently with the content provider for bug fixes; Applications certified for launch; current priorities of all Applications; and flags to easily identify new Applications that have been added to the list
(“Certification Status Document”). Upon submission to Danger of all proposed Certain Premium Content by a third-party developer (or completion of Danger’s development if developed by Danger), Danger shall perform the testing
and certification activities set forth in the “Danger Baseline Application Acceptance Criteria” document (hereinafter, the “Content Certification Plan”), a copy of which has been supplied by Danger to T-Mobile, and which
may be amended by Danger, in its reasonable discretion, from time to time. If Danger amends the Content Certification Plan, Danger will use commercially reasonable efforts to notify T-Mobile of any such amendment at least thirty (30) days prior
to the effective date of such amendment. If T-Mobile reasonably believes that an amendment will negatively impact developers, Danger will modify the amendment to eliminate the negative impact, unless modifying the amendment is not commercially or
technically feasible in which case the parties will work together in good faith to resolve the issue. If Danger discovers any bugs or errors in the proposed Certain Premium Content submitted by a third-party developer, Danger will report such
problems to the third-party developer and will work with the third-party developer to correct such errors. 
 (ii) Danger will manage
the certification process for all Certain Premium Content so that initial testing of titles designated by T-Mobile as “high priority” will have a targeted date to complete initial testing (“Target Date”) within [ * ]
business days following submission and a Target Date for follow-up testing within [ * ] business days following

resubmission. The parties acknowledge that Danger can only support the foregoing testing timeline for [ * ] “high priority” titles at a time. If
T-Mobile designates more than [ * ] titles as “high priority,” Danger will notify T-Mobile and T-Mobile will indicate which [ * ] titles are the highest priority and rank each high priority title in excess of [ * ] in order of
T-Mobile’s priority. T-Mobile and Danger may mutually agree to extend the testing timeline for “high priority” titles on a case by case basis. Danger will notify T-Mobile promptly when each “high priority” title has been
certified by Danger. Danger will manage the certification process for all other Premium Content so that the Target Date for initial testing is set at [ * ] business days following submission by T-Mobile into the Content Certification Plan and the
Target Date for follow-up testing within [ * ] business days following resubmission. Certain Premium Content certified by Danger as being compliant with the Content Certification Plan will be updated on the Certification Status Document. 

(iii) On a monthly basis, Danger will create, maintain, and deliver to T-Mobile a launched content report in the format provided to T-Mobile
and dated October 19, 2007 (which T-Mobile and Danger may mutually agree to update from time to time) with the following information for Applications (“Launched Content Report”): all Applications grouped by each provider,
launched Applications grouped by handset, and pricing for each Application. 
 D. T-Mobile Trial Program. At
T-Mobile’s written request, Danger will provide T-Mobile with the opportunity to preview Danger Sourced Premium Content by placing titles in the T-Mobile Trial Program catalog. At T-Mobile’s written request, Danger will place proposed
T-Mobile Sourced Premium Content in the T-Mobile Trial Program catalog to help facilitate T-Mobile’s evaluation and testing efforts. Following receipt of such request, Danger will use commercially reasonable efforts to place such Premium
Content in the trial catalog within [ * ] business days after receiving such request from T-Mobile. Danger shall create a separate “restricted access” folder in the PDM for use by T-Mobile in the T-Mobile Trial Program. Unless T-Mobile
instructs Danger in writing otherwise, Danger will place all Premium Content in the “restricted access” folder. T-Mobile shall have the right to specify up to [ * ] T-Mobile Trial Program participants that will be allowed access to the
“restricted access” folder and the Premium Content therein. No other T-Mobile Trial Program participants will be permitted to have access to the Premium Content in the “restricted access” folder.  
 E. Security. Danger will provide reasonably appropriate security for T-Mobile Sourced Premium Content that is at least as great as the security it
takes to protect Danger Sourced Content. Danger may not disable or modify any security features or functionality that are part of the T-Mobile Sourced Premium Content and will use commercially reasonable efforts to incorporate security features or
functionality that are provided to Danger by T-Mobile or a third party provider for use in connection with T-Mobile Sourced Premium Content.

 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 

  

 8. 
 [ *
] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

 
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. 
 [ *
] = Certain confidential information contained in this document, marked by brackets, has been omitted and filed separately with the Securities and Exchange Commission pursuant to Rule 406 of the Securities Act of 1933, as amended. 

 
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
