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

 .
           (b) under Patents Claims infringed by the making, using or
           selling 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

 .
           (b) under Patent Claims infringed by the making, using, or

           of such combination), to make, use, sell, offer for sale, have
           made, and/or otherwise dispose of: 1) Modifications made by that

           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

           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 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 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.
      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",
      "MPL", "NPL" 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 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.
 .
      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
      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
