            (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

      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).

            (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
            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

            Version;  3)  for infringements caused by: i) third party
            modifications of Contributor 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-Licensedmeans 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.
