   The Initial Developer hereby grants You a world-wide, royalty-free,
   non-exclusive license, subject to third party intellectual property
   claims:

    a. under intellectual property rights (other than patent or
       trademark) Licensable by Initial Developer to use, reproduce,

       of Original Code, to make, have made, use, practice, sell, and
       offer for sale, and/or otherwise dispose of the Original Code
       (or portions thereof).
    c. the licenses granted in this Section 2.1 (a) and (b) are

       Original Code under the terms of this License.
    d. Notwithstanding Section 2.1 (b) above, no patent license is
       granted: 1) for code that You delete from the Original Code; 2)
       separate from the Original Code; or 3) for infringements caused
       by: i) the modification of the Original Code or ii) the
       combination of the Original Code with other software or
       devices.

  2.2. Contributor Grant.

   Subject to third party intellectual property claims, each
   Contributor hereby grants You a world-wide, royalty-free,
   non-exclusive license

    a. under intellectual property rights (other than patent or
       trademark) Licensable by Contributor, 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 and/or as part of a Larger Work; and
    b. under Patent Claims infringed by the making, using, or selling
       of Modifications made by that Contributor either alone and/or
       in combination with its Contributor Version (or portions of
       such combination), to make, use, sell, offer for sale, have
       made, and/or otherwise dispose of: 1) Modifications made by
       that Contributor (or portions thereof); and 2) the combination

       effective on the date Contributor first makes Commercial Use of
       the Covered Code.
    d. Notwithstanding Section 2.2 (b) above, no patent license is
       granted: 1) for any code that Contributor has deleted from the
       Contributor Version; 2) separate from the Contributor Version;
       3) for infringements caused by: i) third party modifications of

       the Contributor Version) or other devices; or 4) under Patent
       Claims infringed by Covered Code in the absence of
       Modifications made by that Contributor.

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 Contributor has knowledge that a license under a third party's
   intellectual property rights is required to exercise the rights
   granted by such Contributor under Sections 2.1 or 2.2, Contributor
   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
   Contributor obtains such knowledge after the Modification is made
   available as described in Section 3.2, Contributor shall promptly
   modify the LEGAL file in all copies Contributor makes 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 Contributor's Modifications include an application programming
   interface and Contributor has knowledge of patent licenses which
   are reasonably necessary to implement that API, Contributor must
   also include this information in the legal file.

    (c) Representations.

   Contributor represents that, except as disclosed pursuant to Section 3.4
   (a) above, Contributor believes that Contributor's Modifications are
   Contributor's original creation(s) and/or Contributor has
   sufficient rights to grant the rights conveyed by this License.

  3.5. Required Notices.

   You must duplicate the notice in Exhibit A in each file of the
   Source Code. 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)
   where a user would be likely to look for such a notice. If You
   created one or more Modification(s) You may add your name as a
   Contributor to the notice described in Exhibit A. You must also
   duplicate this License in any documentation for the Source Code
   where You describe recipients' rights or ownership rights relating
   to Covered Code. 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 Sections 3.1, 3.2, 3.3, 3.4 and 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 or ownership rights 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, judicial order, 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

   The University of Konstanz ("UKO") 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 the
   University of Konstanz. No one other than the University of
   Konstanz 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 "Pathfinder", "University of Konstanz"
   or any confusingly similar phrase do not appear in your license
   (except to note that your license differs from this License) and
   (b) otherwise make it clear that Your version of the license
   contains terms which differ from the Pathfinder 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

   8.1. 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.

   8.2. If You initiate litigation by asserting a patent infringement
   claim (excluding declatory judgment actions) against Initial
   Developer or a Contributor (the Initial Developer or Contributor
   against whom You file such action is referred to as "Participant")
   alleging that:

    a. such Participant's Contributor Version directly or indirectly
       infringes any patent, then any and all rights granted by such
       Participant to You under Sections 2.1 and/or 2.2 of this
       License shall, upon 60 days notice from Participant terminate
       prospectively, unless if within 60 days after receipt of notice
       You either: (i) agree in writing to pay Participant a mutually
       agreeable reasonable royalty for Your past and future use of
       Modifications made by such Participant, or (ii) withdraw Your
       litigation claim with respect to the Contributor Version
       against such Participant. If within 60 days of notice, a
       reasonable royalty and payment arrangement are not mutually
       agreed upon in writing by the parties or the litigation claim
       is not withdrawn, the rights granted by Participant to You
       under Sections 2.1 and/or 2.2 automatically terminate at the
       expiration of the 60 day notice period specified above.
    b. any software, hardware, or device, other than such
       Participant's Contributor Version, directly or indirectly
       infringes any patent, then any rights granted to You by such
       Participant under Sections 2.1(b) and 2.2(b) are revoked
       effective as of the date You first made, used, sold,
       distributed, or had made, Modifications made by that
       Participant.

   8.3. If You assert a patent infringement claim against Participant
   alleging that such Participant's Contributor Version 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 such Participant under Sections 2.1 or 2.2 shall be
   taken into account in determining the amount or value of any
   payment or license.

   8.4. In the event of termination under Sections 8.1 or 8.2 above,
   all end user license agreements (excluding distributors and
   resellers) which have been validly granted by You or any
   distributor hereunder prior to termination shall survive
   termination.

9. Limitation of liability

   UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
   (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
   INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
   COVERED CODE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO
   ANY 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 THIS 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
   the German law and You hereby irrevocably agree that the Courts of
   Konstanz, Germany, are to have jurisdiction to settle any disputes
   which may arise out of or in connection with this License. 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

   As between Initial Developer and the Contributors, each party is
   responsible for claims and damages arising, directly or indirectly,
   out of its utilization of rights under this License and You agree
   to work with Initial Developer and Contributors to distribute such
   responsibility on an equitable basis. Nothing herein is intended or
   shall be deemed to constitute any admission of liability.

13. Multiple-licensed code

   Initial Developer may designate portions of the Covered Code as
   "Multiple-Licensed". "Multiple-Licensed" means that the Initial
   Developer permits you to utilize portions of the Covered Code under
   Your choice of the Pathfinder Public License or the alternative
   licenses, if any, specified by the Initial Developer in the file
   described in Exhibit A.
