GRANT OF RIGHTS + +a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, +royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute +and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code +form. + +b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, +royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the +Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the +combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such +addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not +apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder. + +c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no +assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property +rights of any other entity. Each Contributor disclaims any liability to Recipient 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, each Recipient hereby assumes sole responsibility to secure any other intellectual property +rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the +Program, it is Recipient's responsibility to acquire that license before distributing the Program. + +d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to +grant the copyright license set forth in this Agreement. + +3. REQUIREMENTS + +A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that: + +a) it complies with the terms and conditions of this Agreement; and + +b) its license agreement: + +i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including +warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and +fitness for a particular purpose; + +ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, +incidental and consequential damages, such as lost profits; + +iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any +other party; and + +iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it +in a reasonable manner on or through a medium customarily used for software exchange. + +When the Program is made available in source code form: + +a) it must be made available under this Agreement; and + +b) a copy of this Agreement must be included with each copy of the Program. + +Contributors may not remove or alter any copyright notices contained within the Program. + +Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows +subsequent Recipients to identify the originator of the Contribution. + +4. COMMERCIAL DISTRIBUTION + +Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and +the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes +the Program in a commercial product offering should do so in a manner which does not create potential liability for +other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor +("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") +against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions +brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such +Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The +obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual +property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial +Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the +Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may + participate in any such claim at its own expense. + +For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is +then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties +related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. +Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to +those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, +the Commercial Contributor must pay those damages. + +5. NO WARRANTY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR +CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, +NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for +determining the appropriateness of using and distributing the Program and assumes all risks associated with its +exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance +with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations. + +6. DISCLAIMER OF LIABILITY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY +DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), +HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR +OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED +HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. GENERAL + +If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or +enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such +provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable. + +If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) +alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such +Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such +litigation is filed. + +All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or +conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such +noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution +of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses + granted by Recipient relating to the Program shall continue and survive. + +Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement +is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish +new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the +right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may +assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the +Agreement will be given a distinguishing version number. The Program (including Contributions) may always be +distributed subject to the version of the Agreement under which it was received. In addition, after a new version of +the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the +new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to +the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or +otherwise. All rights in the Program not expressly granted under this Agreement are reserved. + +This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States +of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause +of action arose. Each party waives its rights to a jury trial in any resulting litigation.

REQUIREMENTS + +A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that: + +a) it complies with the terms and conditions of this Agreement; and + +b) its license agreement: + +i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including +warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and +fitness for a particular purpose; + +ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, +incidental and consequential damages, such as lost profits; + +iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any +other party; and + +iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it +in a reasonable manner on or through a medium customarily used for software exchange. + +When the Program is made available in source code form: + +a) it must be made available under this Agreement; and + +b) a copy of this Agreement must be included with each copy of the Program. + +Contributors may not remove or alter any copyright notices contained within the Program. + +Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows +subsequent Recipients to identify the originator of the Contribution. + +4. COMMERCIAL DISTRIBUTION + +Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and +the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes +the Program in a commercial product offering should do so in a manner which does not create potential liability for +other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor +("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") +against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions +brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such +Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The +obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual +property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial +Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the +Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may + participate in any such claim at its own expense. + +For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is +then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties +related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. +Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to +those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, +the Commercial Contributor must pay those damages. + +5. NO WARRANTY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR +CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, +NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for +determining the appropriateness of using and distributing the Program and assumes all risks associated with its +exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance +with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations. + +6. DISCLAIMER OF LIABILITY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY +DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), +HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR +OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED +HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. GENERAL + +If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or +enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such +provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable. + +If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) +alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such +Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such +litigation is filed. + +All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or +conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such +noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution +of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses + granted by Recipient relating to the Program shall continue and survive. + +Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement +is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish +new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the +right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may +assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the +Agreement will be given a distinguishing version number. The Program (including Contributions) may always be +distributed subject to the version of the Agreement under which it was received. In addition, after a new version of +the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the +new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to +the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or +otherwise. All rights in the Program not expressly granted under this Agreement are reserved. + +This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States +of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause +of action arose. Each party waives its rights to a jury trial in any resulting litigation.

Contributions do not include additions to the Program which: (i) are separate +modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not +derivative works of the Program. + +"Contributor" means any person or entity that distributes the Program. + +"Licensed Patents " mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of +its Contribution alone or when combined with the Program. + +"Program" means the Contributions distributed in accordance with this Agreement. + +"Recipient" means anyone who receives the Program under this Agreement, including all Contributors. + +2. GRANT OF RIGHTS + +a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, +royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute +and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code +form. + +b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, +royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the +Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the +combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such +addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not +apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder. + +c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no +assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property +rights of any other entity. Each Contributor disclaims any liability to Recipient 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, each Recipient hereby assumes sole responsibility to secure any other intellectual property +rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the +Program, it is Recipient's responsibility to acquire that license before distributing the Program. + +d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to +grant the copyright license set forth in this Agreement. + +3. REQUIREMENTS + +A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that: + +a) it complies with the terms and conditions of this Agreement; and + +b) its license agreement: + +i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including +warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and +fitness for a particular purpose; + +ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, +incidental and consequential damages, such as lost profits; + +iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any +other party; and + +iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it +in a reasonable manner on or through a medium customarily used for software exchange. + +When the Program is made available in source code form: + +a) it must be made available under this Agreement; and + +b) a copy of this Agreement must be included with each copy of the Program. + +Contributors may not remove or alter any copyright notices contained within the Program. + +Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows +subsequent Recipients to identify the originator of the Contribution. + +4. COMMERCIAL DISTRIBUTION + +Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and +the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes +the Program in a commercial product offering should do so in a manner which does not create potential liability for +other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor +("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") +against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions +brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such +Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The +obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual +property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial +Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the +Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may + participate in any such claim at its own expense. + +For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is +then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties +related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. +Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to +those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, +the Commercial Contributor must pay those damages. + +5. NO WARRANTY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR +CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, +NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for +determining the appropriateness of using and distributing the Program and assumes all risks associated with its +exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance +with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations. + +6. DISCLAIMER OF LIABILITY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY +DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), +HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR +OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED +HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. GENERAL + +If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or +enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such +provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable. + +If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) +alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such +Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such +litigation is filed. + +All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or +conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such +noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution +of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses + granted by Recipient relating to the Program shall continue and survive. + +Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement +is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish +new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the +right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may +assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the +Agreement will be given a distinguishing version number. The Program (including Contributions) may always be +distributed subject to the version of the Agreement under which it was received. In addition, after a new version of +the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the +new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to +the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or +otherwise. All rights in the Program not expressly granted under this Agreement are reserved. + +This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States +of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause +of action arose. Each party waives its rights to a jury trial in any resulting litigation.

While this license is intended to facilitate the commercial use of the Program, the Contributor who includes +the Program in a commercial product offering should do so in a manner which does not create potential liability for +other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor +("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") +against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions +brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such +Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The +obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual +property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial +Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the +Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may + participate in any such claim at its own expense. + +For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is +then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties +related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. +Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to +those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, +the Commercial Contributor must pay those damages. + +5. NO WARRANTY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR +CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, +NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for +determining the appropriateness of using and distributing the Program and assumes all risks associated with its +exercise of rights under this Agreement , including but not limited to the risks and costs of program errors, compliance +with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations. + +6. DISCLAIMER OF LIABILITY + +EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY +DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), +HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR +OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED +HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +7. GENERAL + +If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or +enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such +provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable. + +If Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) +alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such +Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such +litigation is filed. + +All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or +conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such +noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution +of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses + granted by Recipient relating to the Program shall continue and survive. + +Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement +is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish +new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the +right to modify this Agreement. The Eclipse Foundation is the initial Agreement Steward. The Eclipse Foundation may +assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the +Agreement will be given a distinguishing version number. The Program (including Contributions) may always be +distributed subject to the version of the Agreement under which it was received. In addition, after a new version of +the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the +new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to +the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or +otherwise. All rights in the Program not expressly granted under this Agreement are reserved. + +This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States +of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause +of action arose. Each party waives its rights to a jury trial in any resulting litigation.
