             or any other entity that elects to use this license, ("Licensor") makes publicly available and
             which contains a notice placed by Licensor identifying such program or work as "Original Code"
             and stating that it is subject to the terms of this RealNetworks Public Source License version
             1.0 (or subsequent version thereof) ("License"). You are not required to accept this License.

             its derivative works. These actions are prohibited by law if You do not accept this License.
             Therefore, by modifying, copying or distributing the software (or any work based on the
             software), You indicate your acceptance of this License to do so, and all its terms and
             conditions. In addition, you agree to the terms of this License by clicking the Accept button

             with other software or hardware; and (b) in the case where You are the grantor of rights,
             claims of patents that (i) are now or hereafter acquired, owned by or assigned to You and (ii)

             whichever is longer. You should preferably distribute the Source Code of Your Deployed

          You expressly acknowledge and agree that although Licensor and each Contributor grants the
             licenses to their respective portions of the Covered Code set forth herein, no assurances are
             provided by Licensor or any Contributor that the Covered Code does not infringe the patent or
             other intellectual property rights of any other entity. Licensor and each Contributor disclaim
             any liability to You for claims brought by any other entity based on infringement of
             intellectual property rights or otherwise. As a condition to exercising the rights and
             licenses granted hereunder, You hereby assume sole responsibility to secure any other
             intellectual property rights needed, if any. For example, if a third party patent license is
             required to allow You to make, use, sell, import or offer for sale the Covered Code, it is
             Your responsibility to acquire such license(s).

          Derivative Works. You may create a Derivative Work by combining Covered Code with other code not
             otherwise governed by the terms of this License and distribute the Derivative Work as an
             integrated product. In each such instance, You must make sure the requirements of this License
             are fulfilled for the Covered Code or any portion thereof, including all Modifications.

          You must cause any Derivative Work that you distribute, publish or Externally Deploy, that in
             whole or in part contains or is derived from the Covered Code or any part thereof, to be
             licensed as a whole at no charge to all third parties under the terms of this License and no
             other license except as provided in Section 4.2. You also must make Source Code available for
             the Derivative Work under the same terms as Modifications, described in Sections 2 and 3,

          Compatible Source Licenses. Software modules that have been independently developed without any
             use of Covered Code and which contain no portion of the Covered Code, Modifications or other
             Derivative Works, but are used or combined in any way wtih the Covered Code or any Derivative
             Work to form a larger Derivative Work, are exempt from the conditions described in Section 4.1
             but only to the extent that: the software module, including any software that is linked to,
             integrated with, or part of the same applications as, the software module by any method must
             be wholly subject to one of the Compatible Source Licenses. Notwithstanding the foregoing, all
             Covered Code must be subject to the terms of this License. Thus, the entire Derivative Work
             must be licensed under a combination of the RPSL (for Covered Code) and a Compatible Source
             License for any independently developed software modules within the Derivative Work. The
             foregoing requirement applies even if the Compatible Source License would ordinarily allow the
             software module to link with, or form larger works with, other software that is not subject to
             the Compatible Source License. For example, although the Mozilla Public License v1.1 allows
             Mozilla code to be combined with proprietary software that is not subject to the MPL, if
             MPL-licensed code is used with Covered Code the MPL-licensed code could not be combined or
             linked with any code not governed by the MPL. The general intent of this section 4.2 is to
             enable use of Covered Code with applications that are wholly subject to an acceptable open
             source license. You are responsible for determining whether your use of software with Covered
             Code is allowed under Your license to such software.
               =(6
          Mere aggregation of another work not based on the Covered Code with the Covered Code (or with a
             work based on the Covered Code) on a volume of a storage or distribution medium does not bring
             the other work under the scope of this License. If You deliver the Covered Code for
             combination and/or integration with an application previously provided by You (for example,
             via automatic updating technology), such combination and/or integration constitutes a
             Derivative Work subject to the terms of this License.

          Exclusions From License Grant. Nothing in this License shall be deemed to grant any rights to

             this License shall be interpreted to prohibit Licensor from licensing under different terms

             Modifications, Derivative Works and/or any use or combination of Covered Code with other
             technology provided by Licensor or third parties may require additional patent licenses from

             to any Contributor. No Licensor Marks may be used to endorse or promote products derived from

          Versions of the License. Licensor may publish revised and/or new versions of this License from

             has been published under a particular version of this License, You may continue to use it
             under the terms of that version. You may also choose to use such Original Code under the terms

             applicable law) under this License exceed the amount of ten dollars ($10.00).
