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
