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. 
CUA Office Project 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 CUA Office Project. No one other than CUA Office 
Project 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 "CUA Office", "CUA", "CUAPL", 
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 CUA Office 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 NPL or the alternative licenses, if any, specified 
by the Initial Developer in the file described in Exhibit A.
