(( RealNetworks Public Source License Version 1.0

(Rev. Date October 28, 2002) ))??

   (( 1. ))??
   General Definitions. This License applies to any program or other work which
   RealNetworks, Inc., 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. However, nothing else grants You permission to use,
   copy, modify or distribute the software or 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 or downloading the software. As used in this
   License:

      (( 1.1 ))??
      "Applicable Patent Rights" mean: (a) in the case where Licensor is the
      grantor of rights, claims of patents that (i) are now or hereafter
      acquired, owned by or assigned to Licensor and (ii) are necessarily
      infringed by using or making the Original Code alone and not in
      combination 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) are infringed (directly or
      indirectly) by using or making Your Modifications, taken alone or in
      combination with Original Code.

      (( 1.2 ))??
      "Compatible Source License" means any one of the licenses listed on
      Exhibit B or at https:/www.helixcommunity.org/content/complicense or other
      licenses specifically identified by Licensor in writing. Notwithstanding
      any term to the contrary in any Compatible Source License, any code
      covered by any Compatible Source License that is used with Covered Code
      must be made readily available in Source Code format for royalty-free use
      under the terms of the Compatible Source License or this License.

      (( 1.3 ))??

      Original Code and any Modifications, and/or any respective portions
      thereof.

      (( 1.5 ))??
      "Deploy" means to use, sublicense or distribute Covered Code other than
      for Your internal research and development (R&D) and/or Personal Use, and
      includes without limitation, any and all internal use or distribution of
      Covered Code within Your business or organization except for R&D use
      and/or Personal Use, as well as direct or indirect sublicensing or
      distribution of Covered Code by You to any third party in any form or
      manner.

      (( 1.6 ))??
      "Derivative Work" means either the Covered Code or any derivative work
      under United States copyright law, and including any work containing or
      including any portion of the Covered Code or Modifications, either
      verbatim or with modifications and/or translated into another language.
      Derivative Work also includes any work which combines any portion of
      Covered Code or Modifications with code not otherwise governed by the
      terms of this License.

      (( 1.7 ))??
      "Externally Deploy" means to Deploy the Covered Code in any way that may
      be accessed or used by anyone other than You, used to provide any services
      to anyone other than You, or used in any way to deliver any content to
      anyone other than You, whether the Covered Code is distributed to those
      parties, made available as an application intended for use over a computer
      network, or used to provide services or otherwise deliver content to
      anyone other than You.

      (( 1.8. ))??
      "Interface" means interfaces, functions, properties, class definitions,
      APIs, header files, GUIDs, V-Tables, and/or protocols allowing one piece
      of software, firmware or hardware to communicate or interoperate with
      another piece of software, firmware or hardware.

      (( 1.9 ))??
      "Modifications" mean any addition to, deletion from, and/or change to, the
      substance and/or structure of the Original Code, any previous
      Modifications, the combination of Original Code and any previous
      Modifications, and/or any respective portions thereof. When code is
      released as a series of files, a Modification is: (a) any addition to or
      deletion from the contents of a file containing Covered Code; and/or (b)
      any new file or other representation of computer program statements that
      contains any part of Covered Code.

      (( 1.10 ))??
      "Original Code" means (a) the Source Code of a program or other work as
      originally made available by Licensor under this License, including the
      Source Code of any updates or upgrades to such programs or works made

      (( 1.11 ))??
      "Personal Use" means use of Covered Code by an individual solely for his

      of Covered Code in his or her capacity as an officer, employee, member,
      independent contractor or agent of a corporation, business or organization
      (commercial or non-commercial) does not qualify as Personal Use.

      (( 1.12 ))??
      "Source Code" means the human readable form of a program or other work
      that is suitable for making modifications to it, including all modules it
      contains, plus any associated interface definition files, scripts used to

      or beneficial ownership of such entity.

   (( 2. ))??
   Permitted Uses; Conditions & Restrictions. Subject to the terms and
   conditions of this License, Licensor hereby grants You, effective on the date
   You accept this License (via downloading or using Covered Code or otherwise
   indicating your acceptance of this License), a worldwide, royalty-free,
   non-exclusive copyright license, to the extent of Licensor's copyrights cover
   the Original Code, to do the following:

      (( 2.1 ))??
      You may reproduce, display, perform, modify and Deploy Covered Code,
      provided that in each instance:

         (( (a) ))??
         You must retain and reproduce in all copies of Original Code the
         copyright and other proprietary notices and disclaimers of Licensor as
         they appear in the Original Code, and keep intact all notices in the
         Original Code that refer to this License;

         (( (b) ))??
         You must include a copy of this License with every copy of Source Code
         of Covered Code and documentation You distribute, and You may not offer
         or impose any terms on such Source Code that alter or restrict this
         License or the recipients' rights hereunder, except as permitted under
         Section 6;

         (( c ))??
         You must duplicate, to the extent it does not already exist, the notice
         in Exhibit A in each file of the Source Code of all Your Modifications,
         and cause the modified files to carry prominent notices stating that
         You changed the files and the date of any change;

         (( (d) ))??
         You must make Source Code of all Your Externally Deployed Modifications
         publicly available under the terms of this License, including the
         license grants set forth in Section 3 below, for as long as you Deploy
         the Covered Code or twelve (12) months from the date of initial
         Deployment, whichever is longer. You should preferably distribute the
         Source Code of Your Deployed Modifications electronically (e.g.
         download from a web site); and

         (( (e) ))??
         if You Deploy Covered Code in object code, executable form only, You
         must include a prominent notice, in the code itself as well as in
         related documentation, stating that Source Code of the Covered Code is
         available under the terms of this License with information on how and
         where to obtain such Source Code. You must also include the Object Code
         Notice set forth in Exhibit A in the "about" box or other appropriate
         place where other copyright notices are placed, including any packaging
         materials.

      (( 2.2 ))??
      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).

      (( 2.3 ))??
      Subject to the terms and conditions of this License, Licensor hereby
      grants You, effective on the date You accept this License (via downloading
      or using Covered Code or otherwise indicating your acceptance of this
      License), a worldwide, royalty-free, perpetual, non-exclusive patent
      license under Licensor's Applicable Patent Rights to make, use, sell,
      offer for sale and import the Covered Code, provided that in each instance
      you comply with the terms of this License.

   (( 3. ))??
   Your Grants. In consideration of, and as a condition to, the licenses granted
   to You under this License:

      (( (a) ))??
      You grant to Licensor and all third parties a non-exclusive, perpetual,
      irrevocable, royalty free license under Your Applicable Patent Rights and
      other intellectual property rights owned or controlled by You, to make,
      sell, offer for sale, use, import, reproduce, display, perform, modify,
      distribute and Deploy Your Modifications of the same scope and extent as
      Licensor's licenses under Sections 2.1 and 2.2; and

      (( (b) ))??
      You grant to Licensor and its subsidiaries a non-exclusive, worldwide,
      royalty-free, perpetual and irrevocable license, under Your Applicable
      Patent Rights and other intellectual property rights owned or controlled
      by You, to make, use, sell, offer for sale, import, reproduce, display,
      perform, distribute, modify or have modified (for Licensor and/or its
      subsidiaries), sublicense and distribute Your Modifications, in any form
      and for any purpose, through multiple tiers of distribution.

      (( c ))??
      You agree not use any information derived from Your use and review of the
      Covered Code, including but not limited to any algorithms or inventions
      that may be contained in the Covered Code, for the purpose of asserting
      any of Your patent rights, or assisting a third party to assert any of its
      patent rights, against Licensor or any Contributor.

   (( 4. ))??
   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.

      (( 4.1 ))??
      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, above.

      (( 4.2 ))??
      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
      //** with **//
      __5__
      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.

      (( 4.3 ))??
      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.

   (( 5. ))??
   Exclusions From License Grant. Nothing in this License shall be deemed to
   grant any rights to trademarks, copyrights, patents, trade secrets or any
   other intellectual property of Licensor or any Contributor except as
   expressly stated herein. No right is granted to the trademarks of Licensor or
   any Contributor even if such marks are included in the Covered Code. Nothing
   in this License shall be interpreted to prohibit Licensor from licensing
   under different terms from this License any code that Licensor otherwise
   would have a right to license. 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 Licensor which
   Licensor may grant in its sole discretion. No patent license is granted
   separate from the Original Code or combinations of the Original Code with
   other software or hardware.

      (( 5.1. ))??
      Trademarks. This License does not grant any rights to use the trademarks
      or trade names owned by Licensor ("Licensor Marks" defined in Exhibit C)
      or to any trademark or trade name belonging to any Contributor. No
      Licensor Marks may be used to endorse or promote products derived from the
      Original Code other than as permitted by the Licensor Trademark Policy
      defined in Exhibit C.

   (( 6. ))??
   Additional Terms. You may choose to offer, and to charge a fee for, warranty,
   support, indemnity or liability obligations and/or other rights consistent
   with the scope of the license granted herein ("Additional Terms") to one or
   more recipients of Covered Code. However, You may do so only on Your own
   behalf and as Your sole responsibility, and not on behalf of Licensor or any
   Contributor. You must obtain the recipient's agreement that any such
   Additional Terms are offered by You alone, and You hereby agree to indemnify,
   defend and hold Licensor and every Contributor harmless for any liability
   incurred by or claims asserted against Licensor or such Contributor by reason
   of any such Additional Terms.

   (( 7. ))??
   Versions of the License. Licensor may publish revised and/or new versions of
   this License from time to time. Each version will be given a distinguishing
   version number. Once Original Code 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 of any
   subsequent version of this License published by Licensor. No one other than
   Licensor has the right to modify the terms applicable to Covered Code created
   under this License.

   (( 8. ))??
   NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in part
   pre-release, untested, or not fully tested works. The Covered Code may
   contain errors that could cause failures or loss of data, and may be
   incomplete or contain inaccuracies. You expressly acknowledge and agree that
   use of the Covered Code, or any portion thereof, is at Your sole and entire
   risk. THE COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR
   SUPPORT OF ANY KIND AND LICENSOR AND LICENSOR'S LICENSOR(S) (COLLECTIVELY
   REFERRED TO AS "LICENSOR" FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL
   CONTRIBUTORS EXPRESSLY DISCLAIM ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR
   IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR
   CONDITIONS OF MERCHANTABILITY, OF SATISFACTORY QUALITY, OF FITNESS FOR A
   PARTICULAR PURPOSE, OF ACCURACY, OF QUIET ENJOYMENT, AND NONINFRINGEMENT OF
   THIRD PARTY RIGHTS. LICENSOR AND EACH CONTRIBUTOR DOES NOT WARRANT AGAINST
   INTERFERENCE WITH YOUR ENJOYMENT OF THE COVERED CODE, THAT THE FUNCTIONS
   CONTAINED IN THE COVERED CODE WILL MEET YOUR REQUIREMENTS, THAT THE OPERATION
   OF THE COVERED CODE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT DEFECTS IN
   THE COVERED CODE WILL BE CORRECTED. NO ORAL OR WRITTEN DOCUMENTATION,
   INFORMATION OR ADVICE GIVEN BY LICENSOR, A LICENSOR AUTHORIZED REPRESENTATIVE
   OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. You acknowledge that the Covered
   Code is not intended for use in high risk activities, including, but not
   limited to, the design, construction, operation or maintenance of nuclear
   facilities, aircraft navigation, aircraft communication systems, or air
   traffic control machines in which case the failure of the Covered Code could
   lead to death, personal injury, or severe physical or environmental damage.
   Licensor disclaims any express or implied warranty of fitness for such uses.

   (( 9. ))??
   LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT
   SHALL LICENSOR OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL,
   INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE
   OR YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF,
   WHETHER UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE OR
   STRICT LIABILITY), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF LICENSOR OR SUCH
   CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND
   NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY REMEDY. SOME
   JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF INCIDENTAL OR
   CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. In no event
   shall Licensor's total liability to You for all damages (other than as may be
   required by applicable law) under this License exceed the amount of ten
   dollars ($10.00).

   (( 10. ))??
   Ownership. Subject to the licenses granted under this License, each
   Contributor retains all rights, title and interest in and to any
   Modifications made by such Contributor. Licensor retains all rights, title
   and interest in and to the Original Code and any Modifications made by or on
   behalf of Licensor ("Licensor Modifications"), and such Licensor
   Modifications will not be automatically subject to this License. Licensor
   may, at its sole discretion, choose to license such Licensor Modifications
   under this License, or on different terms from those contained in this
   License or may choose not to license them at all.

   (( 11. ))??
   Termination.

      (( 11.1 ))??
      Term and Termination. The term of this License is perpetual unless
      terminated as provided below. This License and the rights granted
      hereunder will terminate:

         (( (a) ))??
         automatically without notice from Licensor if You fail to comply with
         any term(s) of this License and fail to cure such breach within 30 days
         of becoming aware of such breach;

         (( (b) ))??
         immediately in the event of the circumstances described in Section
         12.5(b); or

         (( c ))??
         automatically without notice from Licensor if You, at any time during
         the term of this License, commence an action for patent infringement
         against Licensor (including by cross-claim or counter claim in a
         lawsuit);

         (( (d) ))??
         upon written notice from Licensor if You, at any time during the term
         of this License, commence an action for patent infringement against any
         third party alleging that the Covered Code itself (excluding
         combinations with other software or hardware) infringes any patent
         (including by cross-claim or counter claim in a lawsuit).

      (( 11.2 ))??
      Effect of Termination. Upon termination, You agree to immediately stop any
      further use, reproduction, modification, sublicensing and distribution of
      the Covered Code and to destroy all copies of the Covered Code that are in
      your possession or control. All sublicenses to the Covered Code which have
      been properly granted prior to termination shall survive any termination
      of this License. Provisions which, by their nature, should remain in
      effect beyond the termination of this License shall survive, including but
      not limited to Sections 3, 5, 8, 9, 10, 11, 12.2 and 13. No party will be
      liable to any other for compensation, indemnity or damages of any sort
      solely as a result of terminating this License in accordance with its
      terms, and termination of this License will be without prejudice to any
      other right or remedy of any party.

   (( 12. ))??
   Miscellaneous.

      (( 12.1 ))??
      Government End Users. The Covered Code is a "commercial item" as defined
      in FAR 2.101. Government software and technical data rights in the Covered
      Code include only those rights customarily provided to the public as
      defined in this License. This customary commercial license in technical
      data and software is provided in accordance with FAR 12.211 (Technical
      Data) and 12.212 (Computer Software) and, for Department of Defense
      purchases, DFAR 252.227-7015 (Technical Data -- Commercial Items) and
      227.7202-3 (Rights in Commercial Computer Software or Computer Software
      Documentation). Accordingly, all U.S. Government End Users acquire Covered
      Code with only those rights set forth herein.

      (( 12.2 ))??
      Relationship of Parties. This License will not be construed as creating an
      agency, partnership, joint venture or any other form of legal association
      between or among You, Licensor or any Contributor, and You will not
      represent to the contrary, whether expressly, by implication, appearance
      or otherwise.

      (( 12.3 ))??
      Independent Development. Nothing in this License will impair Licensor's
      right to acquire, license, develop, have others develop for it, market
      and/or distribute technology or products that perform the same or similar
      functions as, or otherwise compete with, Modifications, Derivative Works,
      technology or products that You may develop, produce, market or
      distribute.

      (( 12.4 ))??
      Waiver; Construction. Failure by Licensor or any Contributor to enforce
      any provision of this License will not be deemed a waiver of future
      enforcement of that or any other provision. Any law or regulation which
      provides that the language of a contract shall be construed against the
      drafter will not apply to this License.

      (( 12.5 ))??
      Severability. (a) If for any reason a court of competent jurisdiction
      finds any provision of this License, or portion thereof, to be
      unenforceable, that provision of the License will be enforced to the
      maximum extent permissible so as to effect the economic benefits and
      intent of the parties, and the remainder of this License will continue in
      full force and effect. (b) Notwithstanding the foregoing, if applicable
      law prohibits or restricts You from fully and/or specifically complying
      with Sections 2 and/or 3 or prevents the enforceability of either of those
      Sections, this License will immediately terminate and You must immediately
      discontinue any use of the Covered Code and destroy all copies of it that
      are in your possession or control.

      (( 12.6 ))??
      Dispute Resolution. Any litigation or other dispute resolution between You
      and Licensor relating to this License shall take place in the Seattle,
      Washington, and You and Licensor hereby consent to the personal
      jurisdiction of, and venue in, the state and federal courts within that
      District with respect to this License. The application of the United
      Nations Convention on Contracts for the International Sale of Goods is
      expressly excluded.

      (( 12.7 ))??
      Export/Import Laws. This software is subject to all export and import laws
      and restrictions and regulations of the country in which you receive the
