  1. Definitions.
  1.1. "Contributor" means each entity that creates or contributes to
      the creation of Modifications.
      1.2. "Contributor Version" means the combination of the Original
      Code, prior Modifications used by a Contributor, and the
      Modifications made by that particular Contributor.
      1.3. "Covered Code" means the Original Code or Modifications or
      the combination of the Original Code and Modifications, in each
      case including portions thereof.
      1.4. "Electronic Distribution Mechanism" means a mechanism
      generally accepted in the software development community for the
      electronic transfer of data.
      1.5. "Executable" means Covered Code in any form other than Source
      Code.
      1.6. "Initial Developer" means the individual or entity identified
      as the Initial Developer in the Source Code notice required by
      Exhibit A.
      1.7. "Larger Work" means a work which combines Covered Code or
      portions thereof with code not governed by the terms of this
      License.
      1.8. "License" means this document.
      1.9. "Modifications" means any addition to or deletion from the
      substance or structure of either the Original Code or any previous
      Modifications. When Covered Code is released as a series of files,
      a Modification is:

  A. Any addition to or deletion from the contents of a file containing
      Original Code or previous Modifications.
      B. Any new file that contains any part of the Original Code or
      previous Modifications.

  1.10. "Original Code" means Source Code of computer software code
  which is described in the Source Code notice required by Exhibit A as
  Original Code, and which, at the time of its release under this
  License is not already Covered Code governed by this License.

  1.11. "Source Code" means the preferred form of the Covered Code for
  making modifications to it, including all modules it contains, plus
  any associated interface definition files, scripts used to control
  compilation and installation of an Executable, or a list of source
  code differential comparisons against either the Original Code or
  another well known, available Covered Code of the Contributor's
  choice. The Source Code can be in a compressed or archival form,
  provided the appropriate decompression or de-archiving software is
  widely available for no charge.

  1.12. "You" means an individual or a legal entity exercising rights
  under, and complying with all of the terms of, this License or a
  future version of this License issued under Section 6.1. For legal
  entities, "You" includes any entity which controls, is controlled by,
  or is under common control with You. For purposes of this definition,
  "control" means (a) the power, direct or indirect, to cause the
  direction or management of such entity, whether by contract or
  otherwise, or (b) ownership of fifty percent (50%) or more of the
  outstanding shares or beneficial ownership of such entity.
  2. Source Code License.
  2.1. The Initial Developer Grant.
      The Initial Developer hereby grants You a world-wide,
      royalty-free, non-exclusive license, subject to third party
      intellectual property claims:

      (a) to use, reproduce, modify, display, perform, sublicense and
      distribute the Original Code (or portions thereof) with or without
      Modifications, or as part of a Larger Work; and
      (b) under patents now or hereafter owned or controlled by Initial
      Developer, to make, have made, use and sell ("Utilize") the
      Original Code (or portions thereof), but solely to the extent that
      any such patent is reasonably necessary to enable You to Utilize
      the Original Code (or portions thereof) and not to any greater
      extent that may be necessary to Utilize further Modifications or
      combinations.

  2.2. Contributor Grant.
  Each Contributor hereby grants You a world-wide, royalty-free,
  non-exclusive license, subject to third party intellectual property
  claims:
  (a) to use, reproduce, modify, display, perform, sublicense and
      distribute the Modifications created by such Contributor (or
      portions thereof) either on an unmodified basis, with other
      Modifications, as Covered Code or as part of a Larger Work; and
      (b) under patents now or hereafter owned or controlled by
      Contributor, to Utilize the Contributor Version (or portions
      thereof), but solely to the extent that any such patent is
      reasonably necessary to enable You to Utilize the Contributor
      Version (or portions thereof), and not to any greater extent that
      may be necessary to Utilize further Modifications or combinations.

  3. Distribution Obligations.
  3.1. Application of License.
      The Modifications which You create or to which You contribute are
      governed by the terms of this License, including without
      limitation Section 2.2. The Source Code version of Covered Code
      may be distributed only under the terms of this License or a
      future version of this License released under Section 6.1, and You
      must include a copy of this License with every copy of the Source
      Code You distribute. You may not offer or impose any terms on any
      Source Code version that alters or restricts 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 3.5.
      3.2. Availability of Source Code.
      Any Modification which You create or to which You contribute must
      be made available in Source Code form under the terms of this
      License either on the same media as an Executable version or via
      an accepted Electronic Distribution Mechanism to anyone to whom
      you made an Executable version available; and if made available
      via Electronic Distribution Mechanism, must remain available for
      at least twelve (12) months after the date it initially became
      available, or at least six (6) months after a subsequent version
      of that particular Modification has been made available to such
      recipients. You are responsible for ensuring that the Source Code
      version remains available even if the Electronic Distribution
      Mechanism is maintained by a third party.
      3.3. Description of Modifications.
      You must cause all Covered Code to which you contribute to contain
      a file documenting the changes You made to create that Covered
      Code and the date of any change. You must include a prominent
      statement that the Modification is derived, directly or
      indirectly, from Original Code provided by the Initial Developer
      and including the name of the Initial Developer in (a) the Source
      Code, and (b) in any notice in an Executable version or related
      documentation in which You describe the origin or ownership of the
      Covered Code.
      3.4. Intellectual Property Matters

  (a) Third Party Claims.
      If You have knowledge that a party claims an intellectual property
      right in particular functionality or code (or its utilization
      under this License), you must include a text file with the source
      code distribution titled "LEGAL" which 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
      Your Modification available as described in Section 3.2, 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 Covered Code that new knowledge has
      been obtained.
      (b) Contributor APIs.
      If Your Modification is an application programming interface and
      You own or control patents which are reasonably necessary to
      implement that API, you must also include this information in the
      LEGAL file.

  3.5. Required Notices.
  You must duplicate the notice in Exhibit A in each file of the Source
  Code, and this License in any documentation for the Source Code, where
  You describe recipients' rights relating to Covered Code. If You
  created one or more Modification(s), You may add your name as a
  Contributor to the notice described in Exhibit A. If it is not
  possible to put such 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 to charge a fee for,
  warranty, support, indemnity or liability obligations to one or more
  recipients of Covered Code. However, You may do so only on Your own
  behalf, and not on behalf of the Initial Developer or any Contributor.
  You must make it absolutely clear than any such warranty, support,
  indemnity or liability obligation is offered by You alone, and You
  hereby agree to indemnify the Initial Developer and every Contributor
  for any liability incurred by the Initial Developer or such
  Contributor as a result of warranty, support, indemnity or liability
  terms You offer.

  3.6. Distribution of Executable Versions.
  You may distribute Covered Code in Executable form only if the
  requirements of Section 3.1-3.5 have been met for that Covered Code,
  and if You include a notice stating that the Source Code version of
  the Covered Code is available under the terms of this License,
  including a description of how and where You have fulfilled the
  obligations of Section 3.2. The notice must be conspicuously included
  in any notice in an Executable version, related documentation or
  collateral in which You describe recipients' rights relating to the
  Covered Code. You may distribute the Executable version of Covered
  Code under a license of Your choice, which may contain terms different
  from this License, provided that You are in compliance with the terms
  of this License and that the license for the Executable version does
  not attempt to limit or alter the recipient's rights in the Source
  Code version from the rights set forth in this License. If You
  distribute the Executable version under a different license You must
  make it absolutely clear that any terms which differ from this License
  are offered by You alone, not by the Initial Developer or any
  Contributor. You hereby agree to indemnify the Initial Developer and
  every Contributor for any liability incurred by the Initial Developer
  or such Contributor as a result of any such terms You offer.

  3.7. Larger Works.
  You may create a Larger Work by combining Covered Code with other code
  not governed by the terms of this License and distribute the Larger
  Work as a single product. In such a case, You must make sure the
  requirements of this License are fulfilled for the Covered Code.
  4. 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 Covered Code due
      to statute or regulation then You must: (a) comply with the terms
      of this License to the maximum extent possible; and (b) describe
      the limitations and the code they affect. Such description must be
      included in the LEGAL file described in Section 3.4 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 to be
      able to understand it.

  5. Application of this License.
  This License applies to code to which the Initial Developer has
      attached the notice in Exhibit A, and to related Covered Code.

  6. Versions of the License.
  6.1. New Versions.
      Netscape Communications Corporation ("Netscape") may publish
      revised and/or new versions of the License from time to time. Each
      version will be given a distinguishing version number.
      6.2. Effect of New Versions.
      Once Covered Code has been published under a particular version of
      the License, You may always continue to use it under the terms of
      that version. You may also choose to use such Covered Code under
      the terms of any subsequent version of the License published by
      Netscape. No one other than Netscape has the right to modify the
      terms applicable to Covered Code created under this License.
      6.3. Derivative Works.
      If you create or use a modified version of this License (which you
      may only do in order to apply it to code which is not already
      Covered Code governed by this License), you must (a) rename Your
      license so that the phrases "Mozilla", "MOZILLAPL", "MOZPL",
      "Netscape", "NPL" or any confusingly similar phrase do not appear
      anywhere in your license and (b) otherwise make it clear that your
      version of the license contains terms which differ from the
      Mozilla Public License and Netscape Public License. (Filling in
      the name of the Initial Developer, Original Code or Contributor in
      the notice described in Exhibit A shall not of themselves be
      deemed to be modifications of this License.)

  7. DISCLAIMER OF WARRANTY.
  COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
      WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
      INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS
      FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
      NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
      OF THE COVERED CODE IS WITH YOU. SHOULD ANY COVERED CODE PROVE
      DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
      OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
      REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
      ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE IS
      AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

  8. TERMINATION.
  This License and the rights granted hereunder will terminate
      automatically if You fail to comply with terms herein and fail to
      cure such breach within 30 days of becoming aware of the breach.
      All sublicenses to the Covered Code which are properly granted
      shall survive any termination of this License. Provisions which,
      by their nature, must remain in effect beyond the termination of
      this License shall survive.

  9. LIMITATION OF LIABILITY.
  UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
      (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE INITIAL
      DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED
      CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO YOU OR
      ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
      CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
      LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
      FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR
      LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE
      POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL
      NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM
      SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS
      SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
      LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT
      EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.

  10. U.S. GOVERNMENT END USERS.
  The Covered Code is a "commercial item," as that term is defined in 48
      C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
      software" and "commercial computer software documentation," as
      such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent
      with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
      (June 1995), all U.S. Government End Users acquire Covered Code
      with only those rights set forth herein.

  11. MISCELLANEOUS.
  This License represents the complete agreement concerning subject
      matter hereof. If any provision of this License is held to be
      unenforceable, such provision shall be reformed only to the extent
      necessary to make it enforceable. This License shall be governed
      by California law provisions (except to the extent applicable law,
      if any, provides otherwise), excluding its conflict-of-law
      provisions. With respect to disputes in which at least one party
      is a citizen of, or an entity chartered or registered to do
      business in, the United States of America: (a) unless otherwise
      agreed in writing, all disputes relating to this License
      (excepting any dispute relating to intellectual property rights)
      shall be subject to final and binding arbitration, with the losing
      party paying all costs of arbitration; (b) any arbitration
      relating to this Agreement shall be held in Santa Clara County,
      California, under the auspices of JAMS/EndDispute; and (c) any
      litigation relating to this Agreement shall be subject to the
      jurisdiction of the Federal Courts of the Northern District of
      California, with venue lying in Santa Clara County, California,
      with the losing party responsible for costs, including without
      limitation, court costs and reasonable attorneys fees and
      expenses. The application of the United Nations Convention on
      Contracts for the International Sale of Goods is expressly
      excluded. Any law or regulation which provides that the language
      of a contract shall be construed against the drafter shall not
      apply to this License.

  12. RESPONSIBILITY FOR CLAIMS.
  Except in cases where another Contributor has failed to comply with
      Section 3.4, You are responsible for damages arising, directly or
      indirectly, out of Your utilization of rights under this License,
      based on the number of copies of Covered Code you made available,
      the revenues you received from utilizing such rights, and other
      relevant factors. You agree to work with affected parties to
      distribute responsibility on an equitable basis.
