      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,
            modify, display, perform, sublicense and distribute the Original Code (or
            portions thereof) with or without Modifications, and/or as part of a Larger
            Work; and

            (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 effective
            on the date Initial Developer first distributes 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 of  Modifications made by that Contributor with
            its Contributor Version (or portions of such combination).

            patent license is granted: 1) for any code that Contributor has deleted
            from the Contributor Version; 2)  separate from the Contributor
            Version;

            Version or ii)  the combination of Modifications made by that Contributor
            with other software  (except as part 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 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 States of America, any litigation relating to this License 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.

      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 MPL or the alternative
      licenses, if any, specified by the Initial Developer in the file described
      in Exhibit A.
