BitTorrent Open Source License
        Version 1.1

      This BitTorrent Open Source License (the "License") applies to the BitTorrent client and
         related software products as well as any updates or maintenance releases of that software
         ("BitTorrent Products") that are distributed by BitTorrent, Inc. ("Licensor"). Any
         BitTorrent Product licensed pursuant to this License is a Licensed Product. Licensed Product, in its
         entirety, is protected by U.S. copyright law. This License identifies the terms under which you may
         use, copy, distribute or modify Licensed Product.
      Preamble
      This Preamble is intended to describe, in plain English, the nature and scope of this License. However,
         this Preamble is not a part of this license. The legal effect of this License is dependent only upon
         the terms of the License and not this Preamble.
      This License complies with the Open Source Definition and is derived from the Jabber Open Source License
         1.0 (the "JOSL"), which has been approved by Open Source Initiative. Sections 4(c) and
         4(f)(iii) from the JOSL have been deleted.
      This License provides that:
      U%_Nshbf<eE
          You may use or give away the Licensed Product, alone or as a component of an aggregate software
             distribution containing programs from several different sources. No royalty or other fee is
             required.
        6OOb:>C%
          Both Source Code and executable versions of the Licensed Product, including Modifications made by
             previous Contributors, are available for your use. (The terms "Licensed Product,"
             "Modifications," "Contributors" and "Source Code" are defined in
             the License.)
        +qiHn!rQ<
          You are allowed to make Modifications to the Licensed Product, and you can create Derivative
             Works from it. (The term "Derivative Works" is defined in the License.)
        $-]>6&UCY.
          By accepting the Licensed Product under the provisions of this License, you agree that any
             Modifications you make to the Licensed Product and then distribute are governed by the
             provisions of this License. In particular, you must make the Source Code of your Modifications
             available to others free of charge and without a royalty.
        Y
          You may sell, accept donations or otherwise receive compensation for executable versions of a
             Licensed Product, without paying a royalty or other fee to the Licensor or any Contributor,
             provided that such executable versions contain your or another Contributor's material
             Modifications. For the avoidance of doubt, to the extent your executable version of a Licensed
             Product does not contain your or another Contributor's material Modifications, you may
             not sell, accept donations or otherwise receive compensation for such executable.
          You may use the Licensed Product for any purpose, but the Licensor is not providing you any
             warranty whatsoever, nor is the Licensor accepting any liability in the event that the
             Licensed Product doesn't work properly or causes you any injury or damages.
        _LxAlR
          If you sublicense the Licensed Product or Derivative Works, you may charge fees for warranty or
             support, or for accepting indemnity or liability obligations to your customers. You cannot
             charge for, sell, accept donations or otherwise receive compensation for the Source Code.
        E\rxB@
          If you assert any patent claims against the Licensor relating to the Licensed Product, or if you
             breach any terms of the License, your rights to the Licensed Product under this License
             automatically terminate.
      You may use this License to distribute your own Derivative Works, in which case the provisions of this
         License will apply to your Derivative Works just as they do to the original Licensed Product.
      Alternatively, you may distribute your Derivative Works under any other OSI-approved Open Source license,
         or under a proprietary license of your choice. If you use any license other than this License,
         however, you must continue to fulfill the requirements of this License (including the provisions
         relating to publishing the Source Code) for those portions of your Derivative Works that consist of
         the Licensed Product, including the files containing
        Modifications.
      New versions of this License may be published from time to time in connection with new versions of a
         Licensed Product or otherwise. You may choose to continue to use the license terms in this version of
         the License for the Licensed Product that was originally licensed hereunder, however, the new versions
         of this License will at all times apply to new versions of the Licensed Product released by Licensor
         after the release of the new version of this License. Only the Licensor has the right to change the
         License terms as they apply to the Licensed Product.
      This License relies on precise definitions for certain terms. Those terms are defined when they are first
         used, and the definitions are repeated for your convenience in a Glossary at the end of the
         License.

             to or deletions from the substance or structure of (i) a file containing a Licensed Product,
             or (ii) any new file that contains any part of a Licensed Product. Hereinafter in this
             License, the term "Licensed Product" shall include all previous Modifications that

          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 patent license is granted separate
             from the Licensed Product, for code that you delete from the Licensed Product, or for
             combinations of the Licensed Product with other software or hardware. No right is granted to
             the trademarks of Licensor or any Contributor even if such marks are included in the Licensed
             Product. 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. As an express condition for your use of the Licensed Product, you hereby agree that
             you will not, without the prior written consent of Licensor, use any trademarks, copyrights,
             patents, trade secrets or any other intellectual property of Licensor or any Contributor
             except as expressly stated herein. For the avoidance of doubt and without limiting the
             foregoing, you hereby agree that you will not use or display any trademark of Licensor or any
             Contributor in any domain name, directory filepath, advertisement, link or other reference to
             you in any manner or in any media.

          Your Obligations Regarding Distribution.
        ?6ODMEa=Slk=~
            Application of This License to Your Modifications. As an express condition for your use of
               the Licensed Product, you hereby agree that any Modifications that you create or to which
               you contribute, and which you distribute, are governed by the terms of this License
               including, without limitation, Section 2. Any Modifications that you create or to which
               you contribute may be distributed only under the terms of this License or a future version
               of this License released under Section 7. You must include a copy of this License with
               every copy of the Modifications you distribute. You agree not to offer or impose any terms
               on any Source Code or executable version of the Licensed Product or Modifications that
               alter or restrict the applicable version of this License or the recipients' rights
               hereunder. However, you may include an additional document offering the additional rights
               described in Section 4(d).
               y
            Availability of Source Code. You must make available, without charge, under the terms of this
               License, the Source Code of the Licensed Product and any Modifications that you
               distribute, either on the same media as you distribute any executable or other form of the
               Licensed Product, or via a mechanism generally accepted in the software development
               community for the electronic transfer of data (an "Electronic Distribution
               Mechanism"). The Source Code for any version of Licensed Product or Modifications
               that you distribute must remain available for as long as any executable or other form of
               the Licensed Product is distributed by you. You are responsible for ensuring that the
               Source Code version remains available even if the Electronic Distribution Mechanism is
               maintained by a third party.
                
            Intellectual Property Matters.
          VUbb&?>#WRf8lk
              Third Party Claims. If you have knowledge that a license to a third party's
                 intellectual property right is required to exercise the rights granted by this
                 License, you must include a text file with the Source Code distribution titled
                 "LEGAL" that describes the claim and the party making the claim in
                 sufficient detail that a recipient will know whom to contact. If you obtain such
                 knowledge after you make any Modifications available as described in Section 4(b), you
                 shall promptly modify the LEGAL file in all copies you make available thereafter and
                 shall take other steps (such as notifying appropriate mailing lists or newsgroups)
                 reasonably calculated to inform those who received the Licensed Product from you that
                 new knowledge has been obtained.
                     |
              Contributor APIs. If your Modifications include an application programming interface
                 ("API") and you have knowledge of patent licenses that are reasonably
                 necessary to implement that API, you must also include this information in the LEGAL
                 file.
                     
              Representations. You represent that, except as disclosed pursuant to 4(c)(i) above, you
                 believe that any Modifications you distribute are your original creations and that you
                 have sufficient rights to grant the rights conveyed by this License.
               iZ$LM8PU%:d!/D`s_=i;
            Required Notices. You must duplicate this License in any documentation you provide along with
               the Source Code of any Modifications you create or to which you contribute, and which you
               distribute, wherever you describe recipients' rights relating to Licensed Product.
               You must duplicate the notice contained in Exhibit A (the "Notice") in each file
               of the Source Code of any copy you distribute of the Licensed Product. If you created a
               Modification, you may add your name as a Contributor to the Notice. If it is not possible
               to put the Notice in a particular Source Code file due to its structure, then you must
               include such Notice in a location (such as a relevant directory file) where a user would
               be likely to look for such a notice. You may choose to offer, and charge a fee for,
               warranty, support, indemnity or liability obligations to one or more recipients of
               Licensed Product. However, you may do so only on your own behalf, and not on behalf of the
               Licensor or any Contributor. You must make it clear that any such warranty, support,
               indemnity or liability obligation is offered by you alone, and you hereby agree to
               indemnify the Licensor and every Contributor for any liability incurred by the Licensor or
               such Contributor as a result of warranty, support, indemnity or liability terms you
               offer.

            Distribution of Executable Versions. You may distribute Licensed Product as an executable
               program under a license of your choice that may contain terms different from this License
               provided (i) you have satisfied the requirements of Sections 4(a) through 4(d) for that
               distribution, (ii) you include a conspicuous notice in the executable version, related
               documentation and collateral materials stating that the Source Code version of the
               Licensed Product is available under the terms of this License, including a description of
               how and where you have fulfilled the obligations of Section 4(b), and (iii) you make it
               clear that any terms that differ from this License are offered by you alone, not by
               Licensor or any Contributor. You hereby agree to indemnify the Licensor and every
               Contributor for any liability incurred by Licensor or such Contributor as a result of any
               terms you offer.
               Ixj'>+h&(%qXi6vLq
            Distribution of Derivative Works. You may create Derivative Works (e.g., combinations of some
               or all of the Licensed Product with other code) and distribute the Derivative Works as
               products under any other license you select, with the proviso that the requirements of
               this License are fulfilled for those portions of the Derivative Works that consist of the
               Licensed Product or any Modifications thereto.
               /<
            Compensation for Distribution of Executable Versions of Licensed Products, Modifications or
               Derivative Works. Notwithstanding any provision of this License to the contrary, by
               distributing, selling, licensing, sublicensing or otherwise making available any Licensed
               Product, or Modification or Derivative Work thereof, you and Licensor hereby acknowledge
               and agree that you may sell, license or sublicense for a fee, accept donations or
               otherwise receive compensation for executable versions of a Licensed Product, without
               paying a royalty or other fee to the Licensor or any other Contributor, provided that such
               executable versions (i) contain your or another Contributor's material Modifications,
               or (ii) are otherwise material Derivative Works. For purposes of this License, an
               executable version of the Licensed Product will be deemed to contain a material
               Modification, or will otherwise be deemed a material Derivative Work, if (a) the Licensed
               Product is modified with your own or a third party's software programs or other code,
               and/or the Licensed Product is combined with a number of your own or a third party's
               software programs or code, respectively, and (b) such software programs or code add or
               contribute material value, functionality or features to the License Product. For the
               avoidance of doubt, to the extent your executable version of a Licensed Product does not
               contain your or another Contributor's material Modifications or is otherwise not a
               material Derivative Work, in each case as contemplated herein, you may not sell, license
               or sublicense for a fee, accept donations or otherwise receive compensation for such
               executable. Additionally, without limitation of the foregoing and notwithstanding any
               provision of this License to the contrary, you cannot charge for, sell, license or
               sublicense for a fee, accept donations or otherwise receive compensation for the Source
               Code.

          Inability to Comply Due to Statute or Regulation. If it is impossible for you to comply with any
             of the terms of this License with respect to some or all of the Licensed Product due to
             statute, judicial order, or regulation, then you must (i) comply with the terms of this
             License to the maximum extent possible, (ii) cite the statute or regulation that prohibits you
             from adhering to the License, and (iii) describe the limitations and the code they affect.
             Such description must be included in the LEGAL file described in Section 4(d), and must be
             included with all distributions of the Source Code. Except to the extent prohibited by statute
             or regulation, such description must be sufficiently detailed for a recipient of ordinary
             skill at computer programming to be able to understand it.

            Effect of New Versions. Once Licensed Product has been published under a particular version
               of the License, you may always continue to use it under the terms of that version,
               provided that any such license be in full force and effect at the time, and has not been
               revoked or otherwise terminated. You may also choose to use such Licensed Product under
               the terms of any subsequent version (but not any prior version) of the License published
               by Licensor. No one other than Licensor has the right to modify the terms applicable to
               Licensed Product created under this License.

               which you may do only in order to apply it to software that is not already a Licensed
               Product under this License, you must rename your license so that it is not confusingly
               similar to this License, and must make it clear that your license contains terms that
               differ from this License. In so naming your license, you may not use any trademark of
               Licensor or any Contributor.

            Automatic Termination Upon Breach. This license and the rights granted hereunder will
               terminate automatically if you fail to comply with the terms herein and fail to cure such
               breach within ten (10) days of being notified of the breach by the Licensor. For purposes
               of this provision, proof of delivery via email to the address listed in the
               'WHOIS' database of the registrar for any website through which you distribute
               or market any Licensed Product, or to any alternate email address which you designate in
               writing to the Licensor, shall constitute sufficient notification. All sublicenses to the
               Licensed Product that are properly granted shall survive any termination of this license
               so long as they continue to complye with the terms of this License. Provisions that, by
               their nature, must remain in effect beyond the termination of this License, shall
               survive.

            Termination Upon Assertion of Patent Infringement. If you initiate litigation by asserting a
               patent infringement claim (excluding declaratory judgment actions) against Licensor or a
               Contributor (Licensor or Contributor against whom you file such an action is referred to
               herein as Respondent) alleging that Licensed Product directly or indirectly infringes any
               patent, then any and all rights granted by such Respondent to you under Sections 1 or 2 of
               this License shall terminate prospectively upon sixty (60) days notice from Respondent
               (the "Notice Period") unless within that Notice Period you either agree in
               writing (i) to pay Respondent a mutually agreeable reasonably royalty for your past or
               future use of Licensed Product made by such Respondent, or (ii) withdraw your litigation

               Respondent alleging that Licensed Product directly or indirectly infringes any patent
               where such claim is resolved (such as by license or settlement) prior to the initiation of
               patent infringement litigation, then the reasonable value of the licenses granted by said
               Respondent under Sections 1 and 2 shall be taken into account in determining the amount or
               value of any payment or license.
