1N/A * Common Public License Version 0.5
1N/A *
1N/A * THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF
1N/A * THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE,
1N/A * REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES
1N/A * RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
1N/A *
1N/A * 1. DEFINITIONS
1N/A *
1N/A * "Contribution" means:
1N/A * a) in the case of the initial Contributor, the
1N/A * initial code and documentation distributed under
1N/A * this Agreement, and
1N/A *
1N/A * b) in the case of each subsequent Contributor:
1N/A * i) changes to the Program, and
1N/A * ii) additions to the Program;
1N/A *
1N/A * where such changes and/or additions to the Program
1N/A * originate from and are distributed by that
1N/A * particular Contributor. A Contribution 'originates'
1N/A * from a Contributor if it was added to the Program
1N/A * by such Contributor itself or anyone acting on such
1N/A * Contributor's behalf. Contributions do not include
1N/A * additions to the Program which: (i) are separate
1N/A * modules of software distributed in conjunction with
1N/A * the Program under their own license agreement, and
1N/A * (ii) are not derivative works of the Program.
1N/A *
1N/A *
1N/A * "Contributor" means any person or entity that distributes
1N/A * the Program.
1N/A *
1N/A * "Licensed Patents " mean patent claims licensable by a
1N/A * Contributor which are necessarily infringed by the use or
1N/A * sale of its Contribution alone or when combined with the
1N/A * Program.
1N/A *
1N/A * "Program" means the Contributions distributed in
1N/A * accordance with this Agreement.
1N/A *
1N/A * "Recipient" means anyone who receives the Program under
1N/A * this Agreement, including all Contributors.
1N/A *
1N/A * 2. GRANT OF RIGHTS
1N/A *
1N/A * a) Subject to the terms of this Agreement, each
1N/A * Contributor hereby grants Recipient a
1N/A * no - exclusive, worldwide, royalt - free copyright
1N/A * license to reproduce, prepare derivative works of,
1N/A * publicly display, publicly perform, distribute and
1N/A * sublicense the Contribution of such Contributor, if
1N/A * any, and such derivative works, in source code and
1N/A * object code form.
1N/A *
1N/A * b) Subject to the terms of this Agreement, each
1N/A * Contributor hereby grants Recipient a
1N/A * no - exclusive, worldwide, royalt - free patent
1N/A * license under Licensed Patents to make, use, sell,
1N/A * offer to sell, import and otherwise transfer the
1N/A * Contribution of such Contributor, if any, in source
1N/A * code and object code form. This patent license
1N/A * shall apply to the combination of the Contribution
1N/A * and the Program if, at the time the Contribution is
1N/A * added by the Contributor, such addition of the
1N/A * Contribution causes such combination to be covered
1N/A * by the Licensed Patents. The patent license shall
1N/A * not apply to any other combinations which include
1N/A * the Contribution. No hardware per se is licensed
1N/A * hereunder.
1N/A *
1N/A * c) Recipient understands that although each
1N/A * Contributor grants the licenses to its
1N/A * Contributions set forth herein, no assurances are
1N/A * provided by any Contributor that the Program does
1N/A * not infringe the patent or other intellectual
1N/A * property rights of any other entity. Each
1N/A * Contributor disclaims any liability to Recipient
1N/A * for claims brought by any other entity based on
1N/A * infringement of intellectual property rights or
1N/A * otherwise. As a condition to exercising the rights
1N/A * and licenses granted hereunder, each Recipient
1N/A * hereby assumes sole responsibility to secure any
1N/A * other intellectual property rights needed, if any.
1N/A *
1N/A * For example, if a third party patent license is
1N/A * required to allow Recipient to distribute the
1N/A * Program, it is Recipient's responsibility to
1N/A * acquire that license before distributing the
1N/A * Program.
1N/A *
1N/A * d) Each Contributor represents that to its
1N/A * knowledge it has sufficient copyright rights in its
1N/A * Contribution, if any, to grant the copyright
1N/A * license set forth in this Agreement.
1N/A *
1N/A * 3. REQUIREMENTS
1N/A *
1N/A * A Contributor may choose to distribute the Program in
1N/A * object code form under its own license agreement, provided
1N/A * that:
1N/A * a) it complies with the terms and conditions of
1N/A * this Agreement; and
1N/A *
1N/A * b) its license agreement:
1N/A * i) effectively disclaims on behalf of all
1N/A * Contributors all warranties and conditions, express
1N/A * and implied, including warranties or conditions of
1N/A * title and no - infringement, and implied warranties
1N/A * or conditions of merchantability and fitness for a
1N/A * particular purpose;
1N/A *
1N/A * ii) effectively excludes on behalf of all
1N/A * Contributors all liability for damages, including
1N/A * direct, indirect, special, incidental and
1N/A * consequential damages, such as lost profits;
1N/A *
1N/A * iii) states that any provisions which differ from
1N/A * this Agreement are offered by that Contributor
1N/A * alone and not by any other party; and
1N/A *
1N/A * iv) states that source code for the Program is
1N/A * available from such Contributor, and informs
1N/A * licensees how to obtain it in a reasonable manner
1N/A * on or through a medium customarily used for
1N/A * software exchange.
1N/A *
1N/A * When the Program is made available in source code form:
1N/A * a) it must be made available under this Agreement;
1N/A * and
1N/A * b) a copy of this Agreement must be included with
1N/A * each copy of the Program.
1N/A *
1N/A * Contributors may not remove or alter any copyright notices
1N/A * contained within the Program.
1N/A *
1N/A * Each Contributor must identify itself as the originator of
1N/A * its Contribution, if any, in a manner that reasonably
1N/A * allows subsequent Recipients to identify the originator of
1N/A * the Contribution.
1N/A *
1N/A *
1N/A * 4. COMMERCIAL DISTRIBUTION
1N/A *
1N/A * Commercial distributors of software may accept certain
1N/A * responsibilities with respect to end users, business
1N/A * partners and the like. While this license is intended to
1N/A * facilitate the commercial use of the Program, the
1N/A * Contributor who includes the Program in a commercial
1N/A * product offering should do so in a manner which does not
1N/A * create potential liability for other Contributors.
1N/A * Therefore, if a Contributor includes the Program in a
1N/A * commercial product offering, such Contributor ("Commercial
1N/A * Contributor") hereby agrees to defend and indemnify every
1N/A * other Contributor ("Indemnified Contributor") against any
1N/A * losses, damages and costs (collectively "Losses") arising
1N/A * from claims, lawsuits and other legal actions brought by a
1N/A * third party against the Indemnified Contributor to the
1N/A * extent caused by the acts or omissions of such Commercial
1N/A * Contributor in connection with its distribution of the
1N/A * Program in a commercial product offering. The obligations
1N/A * in this section do not apply to any claims or Losses
1N/A * relating to any actual or alleged intellectual property
1N/A * infringement. In order to qualify, an Indemnified
1N/A * Contributor must: a) promptly notify the Commercial
1N/A * Contributor in writing of such claim, and b) allow the
1N/A * Commercial Contributor to control, and cooperate with the
1N/A * Commercial Contributor in, the defense and any related
1N/A * settlement negotiations. The Indemnified Contributor may
1N/A * participate in any such claim at its own expense.
1N/A *
1N/A *
1N/A * For example, a Contributor might include the Program in a
1N/A * commercial product offering, Product X. That Contributor
1N/A * is then a Commercial Contributor. If that Commercial
1N/A * Contributor then makes performance claims, or offers
1N/A * warranties related to Product X, those performance claims
1N/A * and warranties are such Commercial Contributor's
1N/A * responsibility alone. Under this section, the Commercial
1N/A * Contributor would have to defend claims against the other
1N/A * Contributors related to those performance claims and
1N/A * warranties, and if a court requires any other Contributor
1N/A * to pay any damages as a result, the Commercial Contributor
1N/A * must pay those damages.
1N/A *
1N/A *
1N/A * 5. NO WARRANTY
1N/A *
1N/A * EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE
1N/A * PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT
1N/A * WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR
1N/A * IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
1N/A * CONDITIONS OF TITLE, NO - INFRINGEMENT, MERCHANTABILITY OR
1N/A * FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
1N/A * responsible for determining the appropriateness of using
1N/A * and distributing the Program and assumes all risks
1N/A * associated with its exercise of rights under this
1N/A * Agreement, including but not limited to the risks and
1N/A * costs of program errors, compliance with applicable laws,
1N/A * damage to or loss of data, programs or equipment, and
1N/A * unavailability or interruption of operations.
1N/A *
1N/A * 6. DISCLAIMER OF LIABILITY
1N/A * EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER
1N/A * RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY
1N/A * FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY,
1N/A * OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
1N/A * LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
1N/A * LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT
1N/A * (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT
1N/A * OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE
1N/A * OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE
1N/A * POSSIBILITY OF SUCH DAMAGES.
1N/A *
1N/A * 7. GENERAL
1N/A *
1N/A * If any provision of this Agreement is invalid or
1N/A * unenforceable under applicable law, it shall not affect
1N/A * the validity or enforceability of the remainder of the
1N/A * terms of this Agreement, and without further action by the
1N/A * parties hereto, such provision shall be reformed to the
1N/A * minimum extent necessary to make such provision valid and
1N/A * enforceable.
1N/A *
1N/A *
1N/A * If Recipient institutes patent litigation against a
1N/A * Contributor with respect to a patent applicable to
1N/A * software (including a cros - claim or counterclaim in a
1N/A * lawsuit), then any patent licenses granted by that
1N/A * Contributor to such Recipient under this Agreement shall
1N/A * terminate as of the date such litigation is filed. In
1N/A * addition, If Recipient institutes patent litigation
1N/A * against any entity (including a cros - claim or
1N/A * counterclaim in a lawsuit) alleging that the Program
1N/A * itself (excluding combinations of the Program with other
1N/A * software or hardware) infringes such Recipient's
1N/A * patent(s), then such Recipient's rights granted under
1N/A * Section 2(b) shall terminate as of the date such
1N/A * litigation is filed.
1N/A *
1N/A * All Recipient's rights under this Agreement shall
1N/A * terminate if it fails to comply with any of the material
1N/A * terms or conditions of this Agreement and does not cure
1N/A * such failure in a reasonable period of time after becoming
1N/A * aware of such noncompliance. If all Recipient's rights
1N/A * under this Agreement terminate, Recipient agrees to cease
1N/A * use and distribution of the Program as soon as reasonably
1N/A * practicable. However, Recipient's obligations under this
1N/A * Agreement and any licenses granted by Recipient relating
1N/A * to the Program shall continue and survive.
1N/A *
1N/A * Everyone is permitted to copy and distribute copies of
1N/A * this Agreement, but in order to avoid inconsistency the
1N/A * Agreement is copyrighted and may only be modified in the
1N/A * following manner. The Agreement Steward reserves the right
1N/A * to publish new versions (including revisions) of this
1N/A * Agreement from time to time. No one other than the
1N/A * Agreement Steward has the right to modify this Agreement.
1N/A *
1N/A * IBM is the initial Agreement Steward. IBM may assign the
1N/A * responsibility to serve as the Agreement Steward to a
1N/A * suitable separate entity. Each new version of the
1N/A * Agreement will be given a distinguishing version number.
1N/A * The Program (including Contributions) may always be
1N/A * distributed subject to the version of the Agreement under
1N/A * which it was received. In addition, after a new version of
1N/A * the Agreement is published, Contributor may elect to
1N/A * distribute the Program (including its Contributions) under
1N/A * the new version. Except as expressly stated in Sections
1N/A * 2(a) and 2(b) above, Recipient receives no rights or
1N/A * licenses to the intellectual property of any Contributor
1N/A * under this Agreement, whether expressly, by implication,
1N/A * estoppel or otherwise. All rights in the Program not
1N/A * expressly granted under this Agreement are reserved.
1N/A *
1N/A *
1N/A * This Agreement is governed by the laws of the State of New
1N/A * York and the intellectual property laws of the United
1N/A * States of America. No party to this Agreement will bring a
1N/A * legal action under this Agreement more than one year after
1N/A * the cause of action arose. Each party waives its rights to
1N/A * a jury trial in any resulting litigation.
