II. Components .
 
    
    The DRM Component, if embedded in a Product, imposes technological restrictions on
the use of that Wrapped Product, including the ability to specify a maximum useable
period for that Wrapped Product and to disable certain functionality within that Wrapped
Product. The functionality which may be utilized to create Wrapped Products through the
DRM Component may differ depending on the DRM Component Engine specified and is
specified in the documentation for the selected DRM Component Engine.
    
    The User Metrics & Communications Component, if packaged with a Wrapped Product,
permits Company (or its authorized designee) to collect, analyze and provide reports to
Microsoft of data regarding End Users uses of that Wrapped Product (the Usage Data),
and facilitates contacts with, and transmission of information to, End Users from within
that Wrapped Product. Company represents and warrants that Usage Data shall not contain
Personal Information of End Users or any End User credit card information. The use,
maintenance, storage and onward disclosure of transaction data regarding the sale or
licensing of Products to End Users, including any Personal Information of End Users
contained therein, shall remain subject to the terms of the Agreement and applicable
laws and regulations. Unless otherwise specified in the applicable SOW or Marketing
Plan, all Usage Data collected through the User Metrics & Communications Component shall
be deemed to be owned by Microsoft and the confidential information of Microsoft for
purposes of the NDA. Notwithstanding the foregoing, but subject to the terms of the
Agreement and any limitations contained in the applicable SOW and/or Marketing Plan,
Microsoft consents to the collection, possession and use of such Usage Data by Company
(or its authorized designee) solely in connection with the performance of the E-Commerce
Activities. The parties agree to work together in good faith to develop any notices,
disclaimers, consents and waivers on the applicable Site or in the Wrapped Product which
are required by applicable law or deemed necessary by Microsoft, (i) sufficient to
notify End Users about the collection of Usage Data, (ii) sufficient to obtain the
unambiguous consent of an End User to receive contacts and/or information from Microsoft
(and, if Microsoft so consents, Company) from within the Wrapped Product, and (iii)
sufficient to permit the transfer of information concerning a customer or End User,
including without limitation Usage Data, to Company (or its authorized designee) in
order to permit Company to perform the relevant E-Commerce Activities.
