145 3.0 DISTRIBUTION OBLIGATIONS
147 3.1 Modifications which You create or to which You contribute are governed
148 by the terms of this Agreement and must be made available under the terms
149 of this Agreement in at least the same form as the Source Code version of
150 Original Software furnished hereunder. Any distribution by You of the
151 Source Code version of Licensed Software must be made under the terms of
152 this Agreement or any future version of this Agreement under Section 11.0,
153 and You must include a copy of this Agreement with each and every copy of
154 such Source Code version of Licensed Software which You distribute. You
155 may not offer or impose any terms on any such Source Code version of
156 Licensed Software that alters or restricts the terms of the applicable
157 version of this Agreement or the Recipients' rights and obligations
160 3.2 You must cause all Licensed Software to which You contribute, i.e.
161 Your Modifications, to contain a clear identification, e.g., a separate
162 file, documenting the changes made by You and identifying You as the
163 Contributor that reasonably allows subsequent Recipients to identify the
164 originator of the Modification. To the extent You create at least one
165 Modification, You may add Your name as a Contributor to the requisite
166 notice described in Section 3.3.
168 3.3 With respect to Your distribution of Licensed Software (or any portion
169 thereof), You must include the following information in a conspicuous
170 location governing such distribution (e.g., a separate file) and on all
171 copies of any Source Code version of Licensed Software You distribute:
173 "The contents herein includes software initially developed by Lucent
174 Technologies Inc. and others, and is subject to the terms of the Lucent
175 Technologies Inc. Plan 9 Open Source License Agreement. A copy of the Plan
176 9 Open Source License Agreement is available at:

178 Technologies at http://www.lucent.com.
180 All software distributed under such Agreement is distributed on an "AS IS"
181 basis, WITHOUT WARRANTY OF ANY KIND, either express or implied. See the

187 are Copyright O 2002. All rights reserved.
189 Contributor(s):___________________________"
191 3.4 You may distribute Licensed Software in Object Code form using this
192 Agreement, or under a license of Your choice provided that You are in
193 compliance with this Agreement and Your license: (a) complies with the
194 terms and conditions of this Agreement; (b) does not limit or alter the
195 Recipient's rights and obligations in the Source Code version of the
196 Licensed Software set forth in this Agreement; (c) states that the Source
197 Code version of the Licensed Software is available from You, and describes
198 how it may be obtained by Recipient; (d) effectively disclaims on behalf
199 of Original Contributor and all Contributors all warranties and
200 conditions, express or implied, including warranties or conditions of
201 title or non-infringement, and implied warranties or conditions of
202 merchantability and fitness for a particular purpose; (e) effectively
203 excludes on behalf of Original Contributor and all Contributors all
204 liability for damages, including direct, indirect, special, incidental,
205 and consequential damages; and (f) clearly states that any terms which
206 differ from this Agreement are offered by You alone, not by Original
207 Contributor or any other Contributor. You hereby agree to indemnify
208 Original Contributor or any other Contributor for any liability incurred
209 by Original Contributor or any other Contributor as result of any such
210 differing terms You offer in Your license.
212 3.5 You may not use the names "Lucent Technologies", "Bell Labs" or any
213 other name associated with Lucent or any Lucent trademark for any purposes
214 other than as specifically provided in this Agreement.
216 3.6 You must include all of the original copyright, labels or other
217 notices on the Licensed Software on any copies of the Licensed Software
218 which You make; and include with the distribution of any Modifications You
219 create a copy (or an offer to provide such a copy at no charge) of the
220 Licensed Software, on the same terms as set forth in this Agreement.
222 3.7 While this Agreement contemplates the commercial use and distribution
223 of Licensed Software, commercial distributors of software may, for a
224 variety of reasons, accept certain responsibilities with respect to
225 customers, licensees, business partners and the like. As such, if You or
226 any Contributor include Licensed Software in a commercial offering
227 ("Commercial Contributor"), such Commercial Contributor agrees to defend
228 and indemnify Original Contributor and all other Contributors
229 (collectively "Indemnified Contributors") against any liability, losses,
230 damages and costs arising from claims, lawsuits and other legal actions
231 brought by any third party against the Indemnified Contributors to the
232 extent caused by the acts or omissions of such Commercial Contributor in
233 connection with its use or distribution of Licensed Software in a
234 commercial offering of any kind.
238 You agree to provide the Original Contributor, at its request, with a copy
239 of the complete Source Code version, Object Code version and related
240 documentation for Modifications created or contributed to by You if
241 distributed in any form, e.g., binary or source. Original Contributor
242 and/or other Contributors shall have unrestricted, nonexclusive,
243 worldwide, perpetual, royalty-free rights, to use, reproduce, modify,
244 display, perform, sublicense and distribute such Modifications, and to
245 grant third parties the right to do so, including without limitation as a
246 part of or with the Licensed Software; and Original Contributor and/or
247 other Contributors shall have the right to license or to otherwise
248 transfer to third parties such Modifications without notice, obligation or
249 recourse to You. You grant to Original Contributor, Contributors and their
250 respective licensees all rights and licenses (including patents) as are
251 necessary to incorporate the Modifications created or contributed and so
252 distributed by You into the Licensed Software and to use, distribute or
253 otherwise exploit such Licensed Software without payment or accounting to
258 Title, ownership rights, and intellectual property rights in the Original
259 Software and the Plan 9 Trademark shall remain in the Original
260 Contributor. Original Contributor and/or the other Contributors reserve
261 all rights not expressly granted to You, and no other licenses are granted
262 or implied. The Licensed Software is protected by copyright laws and
267 1. The licenses and rights granted under this Agreement shall terminate
268 automatically if (i) You fail to comply with all of the terms and
269 conditions herein; or (ii) You initiate or participate in any
270 intellectual property action against Original Contributor.
272 1. The rights and obligations of the parties hereto which by their
273 nature would continue beyond termination of this Agreement shall
274 survive and continue after any such termination of this Agreement.
276 1. Upon termination for any reason, You must destroy all copies of the
277 Licensed Software in Your possession. All sublicenses of Licensed
278 Software which were validly granted by You to third parties under
279 this Agreement shall survive such termination.

323 INFORMED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR ANY CLAIM BY ANY OTHER
324 PARTY. FURTHERMORE, SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
325 LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION AND
326 EXCLUSION MAY NOT APPLY TO YOU. TO THE EXTENT THAT ANY EXCLUSION OF

379 EXHIBIT A - GNU GENERAL PUBLIC LICENSE
383 GNU GENERAL PUBLIC LICENSE
387 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
388 Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
389 verbatim copies of this license document, but changing it is not allowed.
393 The licenses for most software are designed to take away your freedom to
394 share and change it. By contrast, the GNU General Public License is
395 intended to guarantee your freedom to share and change free software--to
396 make sure the software is free for all its users. This General Public
397 License applies to most of the Free Software Foundation's software and to
398 any other program whose authors commit to using it. (Some other Free
399 Software Foundation software is covered by the GNU Library General Public
400 License instead.) You can apply it to your programs, too.
402 When we speak of free software, we are referring to freedom, not price.
403 Our General Public Licenses are designed to make sure that you have the
404 freedom to distribute copies of free software (and charge for this service
405 if you wish), that you receive source code or can get it if you want it,
406 that you can change the software or use pieces of it in new free programs;
407 and that you know you can do these things.
409 To protect your rights, we need to make restrictions that forbid anyone to
410 deny you these rights or to ask you to surrender the rights. These
411 restrictions translate to certain responsibilities for you if you
412 distribute copies of the software, or if you modify it.
414 For example, if you distribute copies of such a program, whether gratis or
415 for a fee, you must give the recipients all the rights that you have. You
416 must make sure that they, too, receive or can get the source code. And you
417 must show them these terms so they know their rights.
419 We protect your rights with two steps: (1) copyright the software, and (2)
420 offer you this license which gives you legal permission to copy,
421 distribute and/or modify the software.
423 Also, for each author's protection and ours, we want to make certain that
424 everyone understands that there is no warranty for this free software. If
425 the software is modified by someone else and passed on, we want its
426 recipients to know that what they have is not the original, so that any
427 problems introduced by others will not reflect on the original authors'
430 Finally, any free program is threatened constantly by software patents. We
431 wish to avoid the danger that redistributors of a free program will
432 individually obtain patent licenses, in effect making the program
433 proprietary. To prevent this, we have made it clear that any patent must
434 be licensed for everyone's free use or not licensed at all.
436 The precise terms and conditions for copying, distribution and
439 GNU GENERAL PUBLIC LICENSE
441 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
443 0. This License applies to any program or other work which contains a
444 notice placed by the copyright holder saying it may be distributed under
445 the terms of this General Public License. The "Program", below, refers to
446 any such program or work, and a "work based on the Program" means either
447 the Program or any derivative work under copyright law: that is to say, a
448 work containing the Program or a portion of it, either verbatim or with
449 modifications and/or translated into another language. (Hereinafter,
450 translation is included without limitation in the term "modification".)
451 Each licensee is addressed as "you".
453 Activities other than copying, distribution and modification are not
454 covered by this License; they are outside its scope. The act of running
455 the Program is not restricted, and the output from the Program is covered
456 only if its contents constitute a work based on the Program (independent
457 of having been made by running the Program). Whether that is true depends
458 on what the Program does.
460 1. You may copy and distribute verbatim copies of the Program's source
461 code as you receive it, in any medium, provided that you conspicuously and
462 appropriately publish on each copy an appropriate copyright notice and
463 disclaimer of warranty; keep intact all the notices that refer to this
464 License and to the absence of any warranty; and give any other recipients
465 of the Program a copy of this License along with the Program.
467 You may charge a fee for the physical act of transferring a copy, and you
468 may at your option offer warranty protection in exchange for a fee.
470 2. You may modify your copy or copies of the Program or any portion of it,
471 thus forming a work based on the Program, and copy and distribute such
472 modifications or work under the terms of Section 1 above, provided that
473 you also meet all of these conditions:
475 a) You must cause the modified files to carry prominent notices stating
476 that you changed the files and the date of any change.
478 b) You must cause any work that you distribute or publish, that in whole
479 or in part contains or is derived from the Program or any part thereof, to
480 be licensed as a whole at no charge to all third parties under the terms
483 c) If the modified program normally reads commands interactively when run,
484 you must cause it, when started running for such interactive use in the
485 most ordinary way, to print or display an announcement including an
486 appropriate copyright notice and a notice that there is no warranty (or
487 else, saying that you provide a warranty) and that users may redistribute
488 the program under these conditions, and telling the user how to view a
489 copy of this License. (Exception: if the Program itself is interactive but
490 does not normally print such an announcement, your work based on the
491 Program is not required to print an announcement.)
493 These requirements apply to the modified work as a whole. If identifiable
494 sections of that work are not derived from the Program, and can be
495 reasonably considered independent and separate works in themselves, then
496 this License, and its terms, do not apply to those sections when you
497 distribute them as separate works. But when you distribute the same
498 sections as part of a whole which is a work based on the Program, the
499 distribution of the whole must be on the terms of this License, whose
500 permissions for other licensees extend to the entire whole, and thus to
501 each and every part regardless of who wrote it.
503 Thus, it is not the intent of this section to claim rights or contest your
504 rights to work written entirely by you; rather, the intent is to exercise
505 the right to control the distribution of derivative or collective works
506 based on the Program.
508 In addition, mere aggregation of another work not based on the Program
509 with the Program (or with a work based on the Program) on a volume of a
510 storage or distribution medium does not bring the other work under the
511 scope of this License.
513 3. You may copy and distribute the Program (or a work based on it, under
514 Section 2) in object code or executable form under the terms of Sections 1
515 and 2 above provided that you also do one of the following:
517 a) Accompany it with the complete corresponding machine-readable source
518 code, which must be distributed under the terms of Sections 1 and 2 above
519 on a medium customarily used for software interchange; or,
521 b) Accompany it with a written offer, valid for at least three years, to
522 give any third party, for a charge no more than your cost of physically
523 performing source distribution, a complete machine-readable copy of the
524 corresponding source code, to be distributed under the terms of Sections 1
525 and 2 above on a medium customarily used for software interchange; or,
527 c) Accompany it with the information you received as to the offer to
528 distribute corresponding source code. (This alternative is allowed only
529 for noncommercial distribution and only if you received the program in
530 object code or executable form with such an offer, in accord with
533 The source code for a work means the preferred form of the work for making
534 modifications to it. For an executable work, complete source code means
535 all the source code for all modules it contains, plus any associated
536 interface definition files, plus the scripts used to control compilation
537 and installation of the executable. However, as a special exception, the
538 source code distributed need not include anything that is normally
539 distributed (in either source or binary form) with the major components
540 (compiler, kernel, and so on) of the operating system on which the
541 executable runs, unless that component itself accompanies the executable.
543 If distribution of executable or object code is made by offering access to
544 copy from a designated place, then offering equivalent access to copy the
545 source code from the same place counts as distribution of the source code,
546 even though third parties are not compelled to copy the source along with
549 4. You may not copy, modify, sublicense, or distribute the Program except
550 as expressly provided under this License. Any attempt otherwise to copy,
551 modify, sublicense or distribute the Program is void, and will
552 automatically terminate your rights under this License. However, parties
553 who have received copies, or rights, from you under this License will not
554 have their licenses terminated so long as such parties remain in full
557 5. You are not required to accept this License, since you have not signed
558 it. However, nothing else grants you permission to modify or distribute
559 the Program or its derivative works. These actions are prohibited by law
560 if you do not accept this License. Therefore, by modifying or distributing
561 the Program (or any work based on the Program), you indicate your
562 acceptance of this License to do so, and all its terms and conditions for
563 copying, distributing or modifying the Program or works based on it.
565 6. Each time you redistribute the Program (or any work based on the
566 Program), the recipient automatically receives a license from the original
567 licensor to copy, distribute or modify the Program subject to these terms
568 and conditions. You may not impose any further restrictions on the
569 recipients' exercise of the rights granted herein. You are not responsible
570 for enforcing compliance by third parties to this License.
572 7. If, as a consequence of a court judgment or allegation of patent
573 infringement or for any other reason (not limited to patent issues),
574 conditions are imposed on you (whether by court order, agreement or
575 otherwise) that contradict the conditions of this License, they do not
576 excuse you from the conditions of this License. If you cannot distribute
577 so as to satisfy simultaneously your obligations under this License and
578 any other pertinent obligations, then as a consequence you may not
579 distribute the Program at all. For example, if a patent license would not
580 permit royalty-free redistribution of the Program by all those who receive
581 copies directly or indirectly through you, then the only way you could
582 satisfy both it and this License would be to refrain entirely from
583 distribution of the Program.
585 If any portion of this section is held invalid or unenforceable under any
586 particular circumstance, the balance of the section is intended to apply
587 and the section as a whole is intended to apply in other circumstances.
589 It is not the purpose of this section to induce you to infringe any
590 patents or other property right claims or to contest validity of any such
591 claims; this section has the sole purpose of protecting the integrity of
592 the free software distribution system, which is implemented by public
593 license practices. Many people have made generous contributions to the
594 wide range of software distributed through that system in reliance on
595 consistent application of that system; it is up to the author/donor to
596 decide if he or she is willing to distribute software through any other
597 system and a licensee cannot impose that choice.
599 This section is intended to make thoroughly clear what is believed to be a
600 consequence of the rest of this License.
602 8. If the distribution and/or use of the Program is restricted in certain
603 countries either by patents or by copyrighted interfaces, the original
604 copyright holder who places the Program under this License may add an
605 explicit geographical distribution limitation excluding those countries,
606 so that distribution is permitted only in or among countries not thus
607 excluded. In such case, this License incorporates the limitation as if
608 written in the body of this License.
610 9. The Free Software Foundation may publish revised and/or new versions of
611 the General Public License from time to time. Such new versions will be
612 similar in spirit to the present version, but may differ in detail to
613 address new problems or concerns.
615 Each version is given a distinguishing version number. If the Program
616 specifies a version number of this License which applies to it and "any
617 later version", you have the option of following the terms and conditions
618 either of that version or of any later version published by the Free
619 Software Foundation. If the Program does not specify a version number of
620 this License, you may choose any version ever published by the Free
623 10. If you wish to incorporate parts of the Program into other free
624 programs whose distribution conditions are different, write to the author
625 to ask for permission. For software which is copyrighted by the Free
626 Software Foundation, write to the Free Software Foundation; we sometimes
627 make exceptions for this. Our decision will be guided by the two goals of
628 preserving the free status of all derivatives of our free software and of
629 promoting the sharing and reuse of software generally.
633 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
634 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
635 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
636 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
637 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
638 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
639 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
640 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
641 REPAIR OR CORRECTION.
643 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
644 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
645 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
646 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
647 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT
648 LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
649 SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
650 WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
651 ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
