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.

COMMERCIAL DISTRIBUTION</b></p> + +<p>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.</p> + +<p>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.</p> + +<p><b>5. NO WARRANTY</b></p> + +<p>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.</p> + +<p><b>6.

GENERAL</b></p> + +<p>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.</p> + +<p>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.</p> + +<p>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.</p> + +<p>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.</p> + +<p>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.</p> + +</body> + +</html>
