Yahoo! Public License, Version 1.0 (YPL)

This Yahoo! Public License (this "Agreement") is a legal agreement that
describes the terms under which Yahoo! Inc., a Delaware corporation having its
principal place of business at 701 First Avenue, Sunnyvale, California 94089
("Yahoo!") will provide software to you via download or otherwise ("Software").
By using the Software, you, an individual or an entity ("You") agree to the
terms of this Agreement.

In consideration of the mutual promises and upon the terms and conditions set
forth below, the parties agree as follows:

   1. Grant of Copyright License

          * 1.1 - Subject to the terms and conditions of this Agreement, Yahoo!
          hereby grants to You, under any and all of its copyright interest in
          and to the Software, a royalty-free, non-exclusive, non-transferable
          license to copy, modify, compile, execute, and distribute the Software
          and Modifications. For the purposes of this Agreement, any change to,
          addition to, or abridgement of the Software made by You is a
          "Modification;" however, any file You add to the Software that does
          not contain any part of the Software is not a "Modification."

          * 1.2 - If You are an individual acting on behalf of a corporation or
          other entity, Your use of the Software or any Modification is subject
          to Your having the authority to bind such corporation or entity to
          this Agreement. Providing copies to persons within such corporation or
          entity is not considered distribution for purposes of this Agreement.

          * 1.3 - For the Software or any Modification You distribute in source
          code format, You must do so only under the terms of this Agreement,
          and You must include a complete copy of this Agreement with Your
          distribution. With respect to any Modification You distribute in
          source code format, the terms of this Agreement will apply to You in
          the same way those terms apply to Yahoo! with respect to the Software.
          In other words, when You are distributing Modifications under this
          Agreement, You "stand in the shoes" of Yahoo! in terms of the rights
          You grant and how the terms and conditions apply to You and the
          licensees of Your Modifications. Notwithstanding the foregoing, when
          You "stand in the shoes" of Yahoo!, You are not subject to the
          jurisdiction provision under Section 7, which requires all disputes
          under this Agreement to be subject to the jurisdiction of federal or
          state courts of northern California.

          * 1.4 - For the Software or any Modification You distribute in
          compiled or object code format, You must also provide recipients with
          access to the Software or Modification in source code format along
          with a complete copy of this Agreement. The distribution of the
          Software or Modifications in compiled or object code format may be
          under a license of Your choice, provided that You are in compliance
          with the terms of this Agreement. In addition, You must make
          absolutely clear that any license terms applying to such Software or
          Modification that differ from this Agreement are offered by You alone
          and not by Yahoo!, and that such license does not restrict recipients
          from exercising rights in the source code to the Software granted by
          Yahoo! under this Agreement or rights in the source code to any
          Modification granted by You as described in Section 1.3.

          * 1.5 - This Agreement does not limit Your right to distribute files
          that are entirely Your own work (i.e., which do not incorporate any
          portion of the Software and are not Modifications) under any terms You
          choose.

   2. Support

          * Yahoo! has no obligation to provide technical support or updates to
          You. Nothing in this Agreement requires Yahoo! to enter into any
          license with You for any other edition of the Software.

   3. Intellectual Property Rights

          * 3.1 - Except for the license expressly granted under copyright in
          Section 1.1, no rights, licenses or forbearances are granted or may
          arise in relation to this Agreement whether expressly, by implication,
          exhaustion, estoppel or otherwise. All rights, including all
          intellectual property rights, that are not expressly granted under
          this Agreement are hereby reserved.

          * 3.2 - In any copy of the Software or in any Modification you create,
          You must retain and reproduce, any and all copyright, patent,
          trademark, and attribution notices that are included in the Software
          in the same form as they appear in the Software. This includes the
          preservation of attribution notices in the form of trademarks or logos
          that exist within a user interface of the Software.

          * 3.3 - This license does not grant You rights to use any party's
          name, logo, or trademarks, except solely as necessary to comply with
          Section 3.2.

   4. Disclaimer of Warranties

          * THE SOFTWARE IS PROVIDED "AS IS" AND WITHOUT WARRANTY OF ANY KIND.
          YAHOO! MAKES NO WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY
          REGARDING OR RELATING TO THE SOFTWARE. SPECIFICALLY, YAHOO! DOES NOT
          WARRANT THAT THE SOFTWARE WILL BE ERROR FREE OR WILL PERFORM IN AN
          UNINTERRUPTED MANNER. TO THE GREATEST EXTENT ALLOWED BY LAW, YAHOO!
          SPECIFICALLY DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY,
          FITNESS FOR A PARTICULAR PURPOSE (EVEN IF YAHOO! HAD BEEN INFORMED OF
          SUCH PURPOSE), AND NONINFRINGEMENT WITH RESPECT TO THE SOFTWARE, ANY
          MODIFICATIONS THERETO AND WITH RESPECT TO THE USE OF THE FOREGOING.

   5. Limitation of Liability

          * IN NO EVENT WILL YAHOO! BE LIABLE FOR ANY DIRECT, INDIRECT,
          INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES OF ANY KIND
          (INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, LOSS OF USE, BUSINESS
          INTERRUPTION, LOSS OF DATA, COST OF COVER) IN CONNECTION WITH OR
          ARISING OUT OF OR RELATING TO THE FURNISHING, PERFORMANCE OR USE OF
          THE SOFTWARE OR ANY OTHER RIGHTS GRANTED HEREUNDER, WHETHER ALLEGED AS
          A BREACH OF CONTRACT OR TORTIOUS CONDUCT, INCLUDING NEGLIGENCE, AND
          EVEN IF YAHOO! HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

   6. Term and Termination

          * 6.1 - This Agreement will continue in effect unless and until
          terminated earlier pursuant to this Section 6.

          * 6.2 - In the event Yahoo! determines that You have breached this
          Agreement, Yahoo! may terminate this Agreement.

          * 6.3 - All licenses granted hereunder shall terminate upon the
          termination of this Agreement. Termination will be in addition to any
          rights and remedies available to Yahoo! at law or equity or under this
          Agreement.

          * 6.4 - Termination of this Agreement will not affect the provisions
          regarding reservation of rights (Section 3.1), provisions disclaiming
          or limiting Yahoo!'s liability (Sections 4 and 5), Termination
          (Section 6) or Miscellaneous (Section 7), which provisions will
          survive termination of this Agreement.

   7. Miscellaneous

          * This Agreement contains the entire agreement of the parties with
          respect to the subject matter of this Agreement and supersedes all
          previous communications, representations, understandings and
          agreements, either oral or written, between the parties with respect
          to said subject matter. The relationship of the parties hereunder is
          that of independent contractors, and this Agreement will not be
          construed as creating an agency, partnership, joint venture or any
          other form of legal association between the parties. If any term,
          condition, or provision in this Agreement is found to be invalid,
          unlawful or unenforceable to any extent, this Agreement will be
          construed in a manner that most closely effectuates the intent of this
          Agreement. Such invalid term, condition or provision will be severed
          from the remaining terms, conditions and provisions, which will
          continue to be valid and enforceable to the fullest extent permitted
          by law. This Agreement will be interpreted and construed in accordance
          with the laws of the State of California and the United States of
          America, without regard to conflict of law principles. The U.N.
          Convention on Contracts for the International Sale of Goods shall not
          apply to this Agreement. All disputes arising out of this Agreement
          involving Yahoo! or any of its subsidiaries shall be subject to the
          jurisdiction of the federal or state courts of northern California,
          with venue lying in Santa Clara County, California. No rights may be
          assigned, no obligations may be delegated, and this Agreement may not
          be transferred by You, in whole or in part, whether voluntary or by
          operation of law, including by way of sale of assets, merger or
          consolidation, without the prior written consent of Yahoo!, and any
          purported assignment, delegation or transfer without such consent
          shall be void ab initio. Any waiver of the provisions of this
          Agreement or of a party's rights or remedies under this Agreement must
          be in writing to be effective. Failure, neglect or delay by a party to
          enforce the provisions of this Agreement or its rights or remedies at
          any time, will not be construed or be deemed to be a waiver of such
          party's rights under this Agreement and will not in any way affect the
          validity of the whole or any part of this Agreement or prejudice such
          party's right to take subsequent action.
