Your Error Corrections and Shared Modifications, of the same scope and
extent as Original Contributor's licenses under Section 2.1 a) above
relative to Research Use and Attachment D relative to Commercial Use.

(b) To Original Contributor. You hereby grant to Original Contributor a
worldwide, royalty-free, non-exclusive, perpetual and irrevocable
license, to the extent of Your Intellectual Property Rights covering

Specifications, to use, reproduce, modify, display and distribute Your
Error Corrections, Shared Modifications and Reformatted Specifications,
in any form, including the right to sublicense such rights through
multiple tiers of distribution.

(c) Other than the licenses expressly granted in Sections 2.2(a) and (b)

retain all right, title, and interest in Your Error Corrections, Shared
Modifications and Reformatted Specifications.

2.3 Contributor Modifications.

You may use, reproduce, modify, display and distribute Contributor Error
Corrections, Shared Modifications and Reformatted Specifications,
obtained by You under this License, to the same scope and extent as with
Original Code, Upgraded Code and Specifications.

2.4 Subcontracting.

You may deliver the Source Code of Covered Code to other Licensees
having at least a Research Use license, for the sole purpose of
furnishing development services to You in connection with Your rights
granted in this License. All such Licensees must execute appropriate
documents with respect to such work consistent with the terms of this
License, and acknowledging their work-made-for-hire status or assigning
exclusive right to the work product and associated Intellectual Property
Rights to You.

*3. Requirements and Responsibilities*.

3.1 Research Use License.

As a condition of exercising the rights granted under Section 2.1(a)
above, You agree to comply with the following:

(a) Your Contribution to the Community. All Error Corrections and Shared
Modifications which You create or contribute to are automatically
subject to the licenses granted under Section 2.2 above. You are
encouraged to license all of Your other Modifications under Section 2.2
as Shared Modifications, but are not required to do so. You agree to
notify Original Contributor of any errors in the Specification.

(b) Source Code Availability. You agree to provide all Your Error
Corrections to Original Contributor as soon as reasonably practicable
and, in any event, prior to Internal Deployment Use or Commercial Use,
if applicable. Original Contributor may, at its discretion, post Source
Code for Your Error Corrections and Shared Modifications on the
Community Webserver. You may also post Error Corrections and Shared
Modifications on a web-server of Your choice; provided, that You must
take reasonable precautions to ensure that only Licensees have access to
such Error Corrections and Shared Modifications. Such precautions shall
include, without limitation, a password protection scheme limited to
Licensees and a click-on, download certification of Licensee status
required of those attempting to download from the server. An example of
an acceptable certification is attached as Attachment A-2.

(c) Notices. All Error Corrections and Shared Modifications You create
or contribute to must include a file documenting the additions and
changes You made and the date of such additions and changes. You must
also include the notice set forth in Attachment A-1 in the file header.
If it is not possible to put the notice in a particular Source Code file
due to its structure, then You must include the notice in a location
(such as a relevant directory file), where a recipient would be most
likely to look for such a notice.

(d) Redistribution.

(i) Source. Covered Code may be distributed in Source Code form only to
another Licensee (except for students as provided below). You may not
offer or impose any terms on any Covered Code that alter the rights,
requirements, or responsibilities of such Licensee. You may distribute
Covered Code to students for use in connection with their course work
and research projects undertaken at accredited educational institutions.
Such students need not be Licensees, but must be given a copy of the
notice set forth in Attachment A-3 and such notice must also be included
in a file header or prominent location in the Source Code made available
to such students.

(ii) Executable. You may distribute Executable version(s) of Covered
Code to Licensees and other third parties only for the purpose of
evaluation and comment in connection with Research Use by You and under
a license of Your choice, but which limits use of such Executable
version(s) of Covered Code only to that purpose.

(iii) Modified Class, Interface and Package Naming. In connection with
Research Use by You only, You may use Original Contributor's class,
Interface and package names only to accurately reference or invoke the
Source Code files You modify. Original Contributor grants to You a
limited license to the extent necessary for such purposes.

(iv) You expressly agree that any distribution, in whole or in part, of
Modifications developed by You shall only be done pursuant to the terms
and conditions of this License.

(e) Extensions.

(i) Covered Code. You may not include any Source Code of Community Code
in any Extensions. You may include the compiled Header Files of
Community Code in an Extension provided that Your use of the Covered
Code, including Heading Files, complies with the Commercial Use License,
the TCK and all other terms of this License.

(ii) Publication. No later than the date on which You first distribute
such Extension for Commercial Use, You must publish to the industry, on
a non-confidential basis and free of all copyright restrictions with
respect to reproduction and use, an accurate and current specification
for any Extension. In addition, You must make available an appropriate
test suite, pursuant to the same rights as the specification,
sufficiently detailed to allow any third party reasonably skilled in the
technology to produce implementations of the Extension compatible with
the specification. Such test suites must be made available as soon as
reasonably practicable but, in no event, later than ninety (90) days
after Your first Commercial Use of the Extension. You must use
reasonable efforts to promptly clarify and correct the specification and
the test suite upon written request by Original Contributor.

(iii) Open. You agree to refrain from enforcing any Intellectual
Property Rights You may have covering any interface(s) of Your
Extension, which would prevent the implementation of such interface(s)
by Original Contributor or any Licensee. This obligation does not
prevent You from enforcing any Intellectual Property Right You have that
would otherwise be infringed by an implementation of Your Extension.

(iv) Interface Modifications and Naming. You may not modify or add to
the GUID space * * "xxxxxxxx-0901-11d1-8B06-00A024406D59" or any other
GUID space designated by Original Contributor. You may not modify any
Interface prefix provided with the Covered Code or any other prefix
designated by Original Contributor.* *

* *

(f) You agree that any Specifications provided to You by Original
Contributor are confidential and proprietary information of Original
Contributor. You must maintain the confidentiality of the Specifications
and may not disclose them to any third party without Original
Contributor's prior written consent. You may only use the Specifications
under the terms of this License and only for the purpose of implementing
the terms of this License with respect to Covered Code. You agree not
use, copy or distribute any such Specifications except as provided in
writing by Original Contributor.

3.2 Commercial Use License.

You may not make Commercial Use of any Covered Code unless You and
Original Contributor have executed a copy of the Commercial Use and
Trademark License attached as Attachment D.

*4. Versions of the License.*

4.1 License Versions.

Original Contributor may publish revised versions of the License from
time to time. Each version will be given a distinguishing version number.

4.2 Effect.

Once a particular version of Covered Code has been provided under a
version of the License, You may always continue to use such Covered Code
under the terms of that version of the License. You may also choose to
use such Covered Code under the terms of any subsequent version of the
License. No one other than Original Contributor has the right to
promulgate License versions.

4.3 Multiple-Licensed Code.

Original Contributor may designate portions of the Covered Code as
"Multiple-Licensed." "Multiple-Licensed" means that the Original
Contributor permits You to utilize those designated portions of the
Covered Code under Your choice of this License or the alternative
license(s), if any, specified by the Original Contributor in an
Attachment to this License.

*5. Disclaimer of Warranty.*

5.1 COVERED CODE PROVIDED AS IS.

Upgraded Code, Error Corrections, Shared Modifications or Specifications
infringe a patent owned or controlled by You.

6.3 Effective of Termination.

Upon termination, You agree to discontinue use of and destroy all copies
of Covered Code in Your possession. All sublicenses to the Covered Code

PRECEDING THE CLAIMED BREACH. IN NO EVENT WILL YOU (RELATIVE TO YOUR
SHARED MODIFICATIONS OR ERROR CORRECTIONS) OR ORIGINAL CONTRIBUTOR BE
LIABLE FOR ANY INDIRECT, PUNITIVE, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES IN CONNECTION WITH OR RISING OUT OF THIS LICENSE (INCLUDING,
WITHOUT LIMITATION, LOSS OF PROFITS, USE, DATA, OR OTHER ECONOMIC
ADVANTAGE), HOWEVER IT ARISES AND ON ANY THEORY OF LIABILITY, WHETHER IN
AN ACTION FOR CONTRACT, STRICT LIABILITY OR TORT (INCLUDING NEGLIGENCE)
OR OTHERWISE, WHETHER OR NOT YOU OR ORIGINAL CONTRIBUTOR HAS BEEN

assign the Commercial Use and Trademark license, the Add-On Technology
License, or the Add-On Technology Source Code Porting License, including
by way of merger (regardless of whether You are the surviving entity) or
acquisition, without Original Contributor's prior written consent.

8.4 Severability.

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. Notwithstanding the foregoing, if You are prohibited by law
from fully and specifically complying with Sections 2.2 or 3, this
License will immediately terminate and You must immediately discontinue
any use of Covered Code.

8.5 Governing Law.

This License shall be governed by the laws of the United States and the
State of Washington, as applied to contracts entered into and to be
performed in Washington between Washington residents. The application of
the United Nations Convention on Contracts for the International Sale of
Goods is expressly excluded. You agree that the state and federal courts
located in Seattle, Washington have exclusive jurisdiction over any

a) Arbitration. Any dispute arising out of or relating to this License
shall be finally settled by arbitration as set out herein, except that
either party may bring any action, in a court of competent jurisdiction
(which jurisdiction shall be exclusive), with respect to any dispute
relating to such party's Intellectual Property Rights or with respect to
Your compliance with the TCK license. Arbitration shall be administered:
(i) by the American Arbitration Association (AAA), (ii) in accordance
with the rules of the United Nations Commission on International Trade
Law (UNCITRAL) (the "Rules") in effect at the time of arbitration as
modified herein; and (iii) the arbitrator will apply the substantive

shall be conducted in English by a single arbitrator selected in
accordance with the Rules, who must be fluent in English and be either a
retired judge or practicing attorney having at least ten (10) years
litigation experience and be reasonably familiar with the technology
matters relative to the dispute. Unless otherwise agreed, arbitration
venue shall be in Seattle, Washington. The arbitrator may award monetary
damages only and nothing shall preclude either party from seeking
provisional or emergency relief from a court of competent jurisdiction.
The arbitrator shall have no authority to award damages in excess of
those permitted in this License and any such award in excess is void.
All awards will be payable in U.S. dollars and may include, for the
prevailing party (i) pre-judgment award interest, (ii) reasonable
attorneys' fees incurred in connection with the arbitration, and (iii)
reasonable costs and expenses incurred in enforcing the award. The

respond to no more than twenty-five single question interrogatories.

8.7 Construction.

Any law or regulation, which provides that the language of a contract
shall be construed against the drafter, shall not apply to this License.

8.8 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.
You agree to pass this notice to our licensees.

8.9 Marketing Activities.

Licensee hereby grants Original Contributor a non-exclusive,
non-transferable, limited license to use the Licensee's company name and
logo ("Licensee Marks") in any presentations, press releases, or
marketing materials solely for the purpose of identifying Licensee as a
member of the Helix Community. Licensee shall provide samples of
Licensee Marks to Original Contributor upon request by Original
Contributor. Original Contributor acknowledges that the Licensee Marks
are the trademarks of Licensee. Original Contributor shall not use the
Licensee Marks in a way that may imply that Original Contributor is an
agency or branch of Licensee. Original Contributor understands and
agrees that the use of any Licensee Marks in connection with this
Agreement shall not create any right, title or interest, in, or to the
Licensee Marks or any Licensee trademarks and that all such use and
goodwill associated with any such trademarks will inure to the benefit
of Licensee. Further the Original Contributor will stop usage of the
Licensee Marks upon Licensee's request.

8.10 Press Announcements.

You may make press announcements or other public statements regarding
this License without the prior written consent of the Original
Contributor, if Your statement is limited to announcing the licensing of
the Covered Code or the availability of Your Product and its
compatibility with the Covered Code. All other public announcements
regarding this license require the prior written consent of the Original
Contributor. Consent requests are welcome at press@helixcommunity.org.

8.11 International Use.

a) Export/Import laws. Covered Code is subject to U.S. export control
laws and may be subject to export or import regulations in other
countries. Each party agrees to comply strictly with all such laws and
regulations and acknowledges their responsibility to obtain such
licenses to export, re-export, or import as may be required. You agree
to pass these obligations to Your licensees.

property protection and enforcement in certain countries, You agree not
to redistribute the Original Code, Upgraded Code, TCK and Specifications
to any country on the list of restricted countries on the Community Web
Server.

8.12 Language.

This License is in the English language only, which language shall be
controlling in all respects, and all versions of this License in any

indicating your acceptance of this License), a worldwide, royalty-free,
non-exclusive copyright license, to the extent of Licensor's copyrights cover
the Original Code, to do the following:

2.1 You may reproduce, display, perform, modify and Deploy Covered Code,
provided that in each instance:

(a) You must retain and reproduce in all copies of Original Code the copyright
and other proprietary notices and disclaimers of Licensor as they appear in the
Original Code, and keep intact all notices in the Original Code that refer to
this License;

(b) You must include a copy of this License with every copy of Source Code of
Covered Code and documentation You distribute, and You may not offer or impose
any terms on such Source Code that alter or restrict this License or the
recipients' rights hereunder, except as permitted under Section 6;

(c) You must duplicate, to the extent it does not already exist, the notice in
Exhibit A in each file of the Source Code of all Your Modifications, and cause
the modified files to carry prominent notices stating that You changed the files
and the date of any change;

(d) You must make Source Code of all Your Externally Deployed Modifications
publicly available under the terms of this License, including the license grants
set forth in Section 3 below, for as long as you Deploy the Covered Code or
twelve (12) months from the date of initial Deployment, whichever is longer. You
should preferably distribute the Source Code of Your Deployed Modifications
electronically (e.g. download from a web site); and

(e) if You Deploy Covered Code in object code, executable form only, You must
include a prominent notice, in the code itself as well as in related
documentation, stating that Source Code of the Covered Code is available under
the terms of this License with information on how and where to obtain such
Source Code. You must also include the Object Code Notice set forth in Exhibit A
in the "about" box or other appropriate place where other copyright notices are
placed, including any packaging materials.

2.2 You expressly acknowledge and agree that although Licensor and each
Contributor grants the licenses to their respective portions of the Covered Code
set forth herein, no assurances are provided by Licensor or any Contributor that
the Covered Code does not infringe the patent or other intellectual property
rights of any other entity. Licensor and each Contributor disclaim any liability
to You for claims brought by any other entity based on infringement of
intellectual property rights or otherwise. As a condition to exercising the
rights and licenses granted hereunder, You hereby assume sole responsibility to
secure any other intellectual property rights needed, if any. For example, if a
third party patent license is required to allow You to make, use, sell, import
or offer for sale the Covered Code, it is Your responsibility to acquire such
license(s).

2.3 Subject to the terms and conditions of this License, Licensor hereby grants
You, effective on the date You accept this License (via downloading or using
Covered Code or otherwise indicating your acceptance of this License), a
worldwide, royalty-free, perpetual, non-exclusive patent license under
Licensor's Applicable Patent Rights to make, use, sell, offer for sale and
import the Covered Code, provided that in each instance you comply with the
terms of this License.

3. Your Grants. In consideration of, and as a condition to, the licenses granted
to You under this License:

(a) You grant to Licensor and all third parties a non-exclusive, perpetual,
irrevocable, royalty free license under Your Applicable Patent Rights and other
intellectual property rights owned or controlled by You, to make, sell, offer
for sale, use, import, reproduce, display, perform, modify, distribute and
Deploy Your Modifications of the same scope and extent as Licensor's licenses
under Sections 2.1 and 2.2; and

(b) You grant to Licensor and its subsidiaries a non-exclusive, worldwide,
royalty-free, perpetual and irrevocable license, under Your Applicable Patent
Rights and other intellectual property rights owned or controlled by You, to
make, use, sell, offer for sale, import, reproduce, display, perform,
distribute, modify or have modified (for Licensor and/or its subsidiaries),
sublicense and distribute Your Modifications, in any form and for any purpose,
through multiple tiers of distribution.

(c) You agree not use any information derived from Your use and review of the
Covered Code, including but not limited to any algorithms or inventions that may
be contained in the Covered Code, for the purpose of asserting any of Your
patent rights, or assisting a third party to assert any of its patent rights,
against Licensor or any Contributor.

4. Derivative Works. You may create a Derivative Work by combining Covered Code
with other code not otherwise governed by the terms of this License and
distribute the Derivative Work as an integrated product. In each such instance,
You must make sure the requirements of this License are fulfilled for the
Covered Code or any portion thereof, including all Modifications.

4.1 You must cause any Derivative Work that you distribute, publish or
Externally Deploy, that in whole or in part contains or is derived from the
Covered Code or any part thereof, to be licensed as a whole at no charge to all
third parties under the terms of this License and no other license except as
provided in Section 4.2. You also must make Source Code available for the
Derivative Work under the same terms as Modifications, described in Sections 2
and 3, above.

4.2 Compatible Source Licenses. Software modules that have been independently
developed without any use of Covered Code and which contain no portion of the
Covered Code, Modifications or other Derivative Works, but are used or combined
in any way wtih the Covered Code or any Derivative Work to form a larger
Derivative Work, are exempt from the conditions described in Section 4.1 but
only to the extent that: the software module, including any software that is
linked to, integrated with, or part of the same applications as, the software
module by any method must be wholly subject to one of the Compatible Source
Licenses. Notwithstanding the foregoing, all Covered Code must be subject to the
terms of this License. Thus, the entire Derivative Work must be licensed under a
combination of the RPSL (for Covered Code) and a Compatible Source License for
any independently developed software modules within the Derivative Work. The
foregoing requirement applies even if the Compatible Source License would
ordinarily allow the software module to link with, or form larger works with,
other software that is not subject to the Compatible Source License. For
example, although the Mozilla Public License v1.1 allows Mozilla code to be
combined with proprietary software that is not subject to the MPL, if
MPL-licensed code is used with Covered Code the MPL-licensed code could not be
combined or linked with any code not governed by the MPL. The general intent of
this section 4.2 is to enable use of Covered Code with applications that are
wholly subject to an acceptable open source license. You are responsible for
determining whether your use of software with Covered Code is allowed under Your
license to such software.

4.3 Mere aggregation of another work not based on the Covered Code with the
Covered Code (or with a work based on the Covered Code) on a volume of a storage
or distribution medium does not bring the other work under the scope of this
License. If You deliver the Covered Code for combination and/or integration with
an application previously provided by You (for example, via automatic updating
technology), such combination and/or integration constitutes a Derivative Work
subject to the terms of this License.

5. Exclusions From License Grant. Nothing in this License shall be deemed to
grant any rights to trademarks, copyrights, patents, trade secrets or any other
intellectual property of Licensor or any Contributor except as expressly stated
herein. No right is granted to the trademarks of Licensor or any Contributor
even if such marks are included in the Covered Code. Nothing in this License
shall be interpreted to prohibit Licensor from licensing under different terms
from this License any code that Licensor otherwise would have a right to
license. Modifications, Derivative Works and/or any use or combination of
Covered Code with other technology provided by Licensor or third parties may
require additional patent licenses from Licensor which Licensor may grant in its
sole discretion. No patent license is granted separate from the Original Code or
combinations of the Original Code with other software or hardware.

5.1. Trademarks. This License does not grant any rights to use the trademarks or
trade names owned by Licensor ("Licensor Marks" defined in Exhibit C) or to any
trademark or trade name belonging to any Contributor. No Licensor Marks may be
used to endorse or promote products derived from the Original Code other than as
permitted by the Licensor Trademark Policy defined in Exhibit C.

6. Additional Terms. You may choose to offer, and to charge a fee for, warranty,
support, indemnity or liability obligations and/or other rights consistent with
the scope of the license granted herein ("Additional Terms") to one or more
recipients of Covered Code. However, You may do so only on Your own behalf and
as Your sole responsibility, and not on behalf of Licensor or any Contributor.
You must obtain the recipient's agreement that any such Additional Terms are
offered by You alone, and You hereby agree to indemnify, defend and hold
Licensor and every Contributor harmless for any liability incurred by or claims
asserted against Licensor or such Contributor by reason of any such Additional
Terms.

7. Versions of the License. Licensor may publish revised and/or new versions of
this License from time to time. Each version will be given a distinguishing
version number. Once Original Code has been published under a particular version
of this License, You may continue to use it under the terms of that version. You
may also choose to use such Original Code under the terms of any subsequent
version of this License published by Licensor. No one other than Licensor has
the right to modify the terms applicable to Covered Code created under this
License.

8. NO WARRANTY OR SUPPORT. The Covered Code may contain in whole or in part
pre-release, untested, or not fully tested works. The Covered Code may contain
errors that could cause failures or loss of data, and may be incomplete or
contain inaccuracies. You expressly acknowledge and agree that use of the
Covered Code, or any portion thereof, is at Your sole and entire risk. THE
COVERED CODE IS PROVIDED "AS IS" AND WITHOUT WARRANTY, UPGRADES OR SUPPORT OF
ANY KIND AND LICENSOR AND LICENSOR'S LICENSOR(S) (COLLECTIVELY REFERRED TO AS
"LICENSOR" FOR THE PURPOSES OF SECTIONS 8 AND 9) AND ALL CONTRIBUTORS EXPRESSLY
DISCLAIM ALL WARRANTIES AND/OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT
NOT LIMITED TO, THE IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY, OF
SATISFACTORY QUALITY, OF FITNESS FOR A PARTICULAR PURPOSE, OF ACCURACY, OF QUIET
ENJOYMENT, AND NONINFRINGEMENT OF THIRD PARTY RIGHTS. LICENSOR AND EACH
CONTRIBUTOR DOES NOT WARRANT AGAINST INTERFERENCE WITH YOUR ENJOYMENT OF THE
COVERED CODE, THAT THE FUNCTIONS CONTAINED IN THE COVERED CODE WILL MEET YOUR
REQUIREMENTS, THAT THE OPERATION OF THE COVERED CODE WILL BE UNINTERRUPTED OR
ERROR-FREE, OR THAT DEFECTS IN THE COVERED CODE WILL BE CORRECTED. NO ORAL OR
WRITTEN DOCUMENTATION, INFORMATION OR ADVICE GIVEN BY LICENSOR, A LICENSOR
AUTHORIZED REPRESENTATIVE OR ANY CONTRIBUTOR SHALL CREATE A WARRANTY. You
acknowledge that the Covered Code is not intended for use in high risk
activities, including, but not limited to, the design, construction, operation
or maintenance of nuclear facilities, aircraft navigation, aircraft
communication systems, or air traffic control machines in which case the failure
of the Covered Code could lead to death, personal injury, or severe physical or
environmental damage. Licensor disclaims any express or implied warranty of
fitness for such uses.

9. LIMITATION OF LIABILITY. TO THE EXTENT NOT PROHIBITED BY LAW, IN NO EVENT
SHALL LICENSOR OR ANY CONTRIBUTOR BE LIABLE FOR ANY INCIDENTAL, SPECIAL,
INDIRECT OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATING TO THIS LICENSE OR
YOUR USE OR INABILITY TO USE THE COVERED CODE, OR ANY PORTION THEREOF, WHETHER
UNDER A THEORY OF CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE OR STRICT
LIABILITY), PRODUCTS LIABILITY OR OTHERWISE, EVEN IF LICENSOR OR SUCH
CONTRIBUTOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES AND
NOTWITHSTANDING THE FAILURE OF ESSENTIAL PURPOSE OF ANY REMEDY. SOME
JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY OF INCIDENTAL OR
CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. In no event
shall Licensor's total liability to You for all damages (other than as may be
required by applicable law) under this License exceed the amount of ten dollars
($10.00).

10. Ownership. Subject to the licenses granted under this License, each
Contributor retains all rights, title and interest in and to any Modifications
made by such Contributor. Licensor retains all rights, title and interest in and
to the Original Code and any Modifications made by or on behalf of Licensor
("Licensor Modifications"), and such Licensor Modifications will not be
automatically subject to this License. Licensor may, at its sole discretion,
choose to license such Licensor Modifications under this License, or on
different terms from those contained in this License or may choose not to
license them at all.

11. Termination.

11.1 Term and Termination. The term of this License is perpetual unless
terminated as provided below. This License and the rights granted hereunder will

(b) immediately in the event of the circumstances described in Section 12.5(b);
or

(c) automatically without notice from Licensor if You, at any time during the
term of this License, commence an action for patent infringement against
Licensor (including by cross-claim or counter claim in a lawsuit);

(d) upon written notice from Licensor if You, at any time during the term of
this License, commence an action for patent infringement against any third party
alleging that the Covered Code itself (excluding combinations with other
software or hardware) infringes any patent (including by cross-claim or counter
claim in a lawsuit).

11.2 Effect of Termination. Upon termination, You agree to immediately stop any
further use, reproduction, modification, sublicensing and distribution of the
Covered Code and to destroy all copies of the Covered Code that are in your
possession or control. All sublicenses to the Covered Code which have been
properly granted prior to termination shall survive any termination of this
License. Provisions which, by their nature, should remain in effect beyond the
termination of this License shall survive, including but not limited to Sections
3, 5, 8, 9, 10, 11, 12.2 and 13. No party will be liable to any other for
compensation, indemnity or damages of any sort solely as a result of terminating

Software) and, for Department of Defense purchases, DFAR 252.227-7015 (Technical
Data -- Commercial Items) and 227.7202-3 (Rights in Commercial Computer Software
or Computer Software Documentation). Accordingly, all U.S. Government End Users
acquire Covered Code with only those rights set forth herein.

12.2 Relationship of Parties. This License will not be construed as creating an
agency, partnership, joint venture or any other form of legal association
between or among You, Licensor or any Contributor, and You will not represent to
the contrary, whether expressly, by implication, appearance or otherwise.

12.3 Independent Development. Nothing in this License will impair Licensor's
right to acquire, license, develop, have others develop for it, market and/or
distribute technology or products that perform the same or similar functions as,
or otherwise compete with, Modifications, Derivative Works, technology or
products that You may develop, produce, market or distribute.

12.4 Waiver; Construction. Failure by Licensor or any Contributor to enforce any
provision of this License will not be deemed a waiver of future enforcement of
that or any other provision. Any law or regulation which provides that the
language of a contract shall be construed against the drafter will not apply to
this License.

12.5 Severability. (a) If for any reason a court of competent jurisdiction finds
any provision of this License, or portion thereof, to be unenforceable, that
provision of the License will be enforced to the maximum extent permissible so
as to effect the economic benefits and intent of the parties, and the remainder
of this License will continue in full force and effect. (b) Notwithstanding the
foregoing, if applicable law prohibits or restricts You from fully and/or
specifically complying with Sections 2 and/or 3 or prevents the enforceability
of either of those Sections, this License will immediately terminate and You
must immediately discontinue any use of the Covered Code and destroy all copies
of it that are in your possession or control.

12.6 Dispute Resolution. Any litigation or other dispute resolution between You
and Licensor relating to this License shall take place in the Seattle,

authorizations.
