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. 
Ê
ÊÊÊ(c)ÊÊÊ 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.Ê 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.Ê If
You created one or more Modification(s) You may add your name as a Contributor
to the notice described in Exhibit A.Ê 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.Ê 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.Ê 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.Ê 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")Ê alleging that:

   (a)Ê 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)Ê 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.Ê 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)Ê 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.Ê 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.Ê In the event of termination under Sections 8.1 or 8.2 above,Ê 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.Ê Multiple-Licensed means that the Initial Developer permits
you to utilize portions of the Covered Code under Your choice of the NPL or the
alternative licenses, if any, specified by the Initial Developer in the file
described in Exhibit A.
