 3. Distribution Obligations.
 .
 3.1. Availability of Source Code.
 .
 Any Covered Software that You distribute or otherwise make available
 in Executable form must also be made available  in Source Code form
 and that Source Code form must be distributed only under the terms of
 this License. You must include a copy of this License with every copy
 of the Source Code form of the Covered Software You distribute or
 otherwise make available. You must inform recipients of any such
 Covered Software in Executable form as to how they can obtain such
 Covered Software in Source Code form in a reasonable manner on or
 through a medium customarily used for software exchange.
 .
 3.2. Modifications.
 .
 The Modifications that You create or to which You contribute are
 governed by the terms of this License. You represent that You believe
 Your Modifications are Your original creation(s) and/or You have
 sufficient rights to grant the rights conveyed by this License.
 .
 3.3. Required Notices.
 .
 You must include a notice in each of Your Modifications that
 identifies You as the Contributor of the Modification.  You may not
 remove or alter any copyright, patent or trademark notices contained
 within the Covered Software, or any notices of licensing or any
 descriptive text giving attribution to any Contributor or the Initial
 Developer.
 .
 3.4. Application of Additional Terms.
 .
 You may not offer or impose any terms on any Covered Software in
 Source Code form that alters or restricts the applicable version of
 this License or the recipients’ rights hereunder. You may choose to
 offer, and to charge a fee for, warranty, support, indemnity or
 liability obligations to one or more recipients of Covered Software.
 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 that 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.
 .
 3.5. Distribution of Executable Versions.
 .
 You may distribute the Executable form of the Covered Software under
 the terms of this License or under the terms of 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 form does not attempt to limit or
 alter the recipient’s rights in the Source Code form from the rights
 set forth in this License. If You distribute the Covered Software in
 Executable form 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
 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.
 .
 3.6. Larger Works.
 .
 You may create a Larger Work by combining Covered Software 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
 Software.
 .
 Versions of the License.
 .
 4.1. New Versions.
 .
 Sun Microsystems, Inc. is the initial license steward and may publish
 revised and/or new versions of this License from time to time. Each
 version will be given a distinguishing version number. Except as
 provided in Section 4.3, no one other than the license steward has
 the right to modify this License.
 .
 4.2. Effect of New Versions.
 .
 You may always continue to use, distribute or otherwise make the
 Covered Software available under the terms of the version of the
 License under which You originally received the Covered Software. If
 the Initial Developer includes a notice in the Original Software
 prohibiting it from being distributed or otherwise made available
 under any subsequent version of the License, You must distribute and
 make the Covered Software available under the terms of the version of
 the License under which You originally received the Covered
 Software. Otherwise, You may also choose to use, distribute or
 otherwise make the Covered Software available under the terms of any
 subsequent version of the License published by the license steward.
 .
 4.3. Modified Versions.
 .
 When You are an Initial Developer and You want to create a new
 license for Your Original Software, You may create and use a modified
 version of this License if You: (a) rename the license and remove any
 references to the name of the license steward (except to note that
 the license differs from this License); and (b) otherwise make it
 clear that the license contains terms which differ from this License.
 .
 5. DISCLAIMER OF WARRANTY.
 .
 COVERED SOFTWARE 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 SOFTWARE 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 SOFTWARE IS WITH YOU.  SHOULD ANY COVERED SOFTWARE 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 SOFTWARE IS AUTHORIZED
 HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
 .
 6. TERMINATION.
 .
 6.1. 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. Provisions which, by their nature, must remain in effect
 beyond the termination of this License shall survive.
 .
 6.2. If You assert a patent infringement claim (excluding declaratory
 judgment actions) against Initial Developer or a Contributor (the
 Initial Developer or Contributor against whom You assert such claim
 is referred to as “Participant”) alleging that the Participant
 Software (meaning the Contributor Version where the Participant is a
 Contributor or the Original Software where the Participant is the
 Initial Developer) directly or indirectly infringes any patent, then
 any and all rights granted directly or indirectly to You by such
 Participant, the Initial Developer (if the Initial Developer is not
 the Participant) and all Contributors under Sections 2.1 and/or 2.2
 of this License shall, upon 60 days notice from Participant terminate
 prospectively and automatically at the expiration of such 60 day
 notice period, unless if within such 60 day period You withdraw Your
 claim with respect to the Participant Software against such
 Participant either unilaterally or pursuant to a written agreement
 with Participant.
 .
 6.3. If You assert a patent infringement claim against Participant
 alleging that the Participant Software 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.
 .
 6.4. In the event of termination under Sections 6.1 or 6.2 above, all
 end user licenses that have been validly granted by You or any
 distributor hereunder prior to termination (excluding licenses
 granted to You by any distributor) shall survive termination.
 .
 7. 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 SOFTWARE, 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.
 .
 8. U.S. GOVERNMENT END USERS.
 .
 The Covered Software is a “commercial item,” as that term is defined
 in 48 C.F.R. 2.101 (Oct. 1995), consisting of “commercial computer
 software” (as that term is defined at 48 C.F.R. § 252.227-7014(a)(1))
 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 Software with
 only those rights set forth herein. This U.S. Government Rights
 clause is in lieu of, and supersedes, any other FAR, DFAR, or other
 clause or provision that addresses Government rights in computer
 software under this License.
 .
 9. 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
 the law of the jurisdiction specified in a notice contained within
 the Original Software (except to the extent applicable law, if any,
 provides otherwise), excluding such jurisdiction’s conflict-of-law
 provisions. Any litigation relating to this License shall be subject
 to the jurisdiction of the courts located in the jurisdiction and
 venue specified in a notice contained within the Original Software,
 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. You agree that You alone are responsible for compliance
 with the United States export administration regulations (and the
 export control laws and regulation of any other countries) when You
 use, distribute or otherwise make available any Covered Software.
 .
 10. 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.
 .
 NOTICE PURSUANT TO SECTION 9 OF THE COMMON DEVELOPMENT AND
 DISTRIBUTION LICENSE (CDDL)
 .
 The OpenSolaris code released under the CDDL shall be governed by the
 laws of the State of California (excluding conflict-of-law
 provisions). Any litigation relating to this License shall be subject
 to the jurisdiction of the Federal Courts of the Northern District of
 California and the state courts of the State of California, with
 venue lying in Santa Clara County, California.
