ANY USE, REPRODUCTION OR DISTRIBUTION OF THE 29PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT. 30 311. DEFINITIONS 32 33"Contribution" means: 34 35 a. in the case of Lucent Technologies Inc. ("LUCENT"), the Original 36 Program, and 37 b. in the case of each Contributor, 38 39 i. changes to the Program, and 40 ii. additions to the Program; 41 42 where such changes and/or additions to the Program were added to the 43 Program by such Contributor itself or anyone acting on such 44 Contributor's behalf, and the Contributor explicitly consents, in 45 accordance with Section 3C, to characterization of the changes and/or 46 additions as Contributions. 47 48"Contributor" means LUCENT and any other entity that has Contributed a 49Contribution to the Program. 50 51"Distributor" means a Recipient that distributes the Program, 52modifications to the Program, or any part thereof. 53 54"Licensed Patents" mean patent claims licensable by a Contributor 55which are necessarily infringed by the use or sale of its Contribution 56alone or when combined with the Program. 57 58"Original Program" means the original version of the software 59accompanying this Agreement as released by LUCENT, including source 60code, object code and documentation, if any. 61 62"Program" means the Original Program and Contributions or any part 63thereof 64 65"Recipient" means anyone who receives the Program under this 66Agreement, including all Contributors. 67 682. GRANT OF RIGHTS 69 70 a. Subject to the terms of this Agreement, each Contributor hereby 71 grants Recipient a non-exclusive, worldwide, royalty-free copyright 72 license to reproduce, prepare derivative works of, publicly display, 73 publicly perform, distribute and sublicense the Contribution of such 74 Contributor, if any, and such derivative works, in source code and 75 object code form. 76 77 b. Subject to the terms of this Agreement, each Contributor hereby 78 grants Recipient a non-exclusive, worldwide, royalty-free patent 79 license under Licensed Patents to make, use, sell, offer to sell, 80 import and otherwise transfer the Contribution of such Contributor, if 81 any, in source code and object code form. The patent license granted 82 by a Contributor shall also apply to the combination of the 83 Contribution of that Contributor and the Program if, at the time the 84 Contribution is added by the Contributor, such addition of the 85 Contribution causes such combination to be covered by the Licensed 86 Patents. The patent license granted by a Contributor shall not apply 87 to (i) any other combinations which include the Contribution, nor to 88 (ii) Contributions of other Contributors. No hardware per se is 89 licensed hereunder. 90 91 c. Recipient understands that although each Contributor grants the 92 licenses to its Contributions set forth herein, no assurances are 93 provided by any Contributor that the Program does not infringe the 94 patent or other intellectual property rights of any other entity. Each 95 Contributor disclaims any liability to Recipient for claims brought by 96 any other entity based on infringement of intellectual property rights 97 or otherwise. As a condition to exercising the rights and licenses 98 granted hereunder, each Recipient hereby assumes sole responsibility 99 to secure any other intellectual property rights needed, if any. For 100 example, if a third party patent license is required to allow 101 Recipient to distribute the Program, it is Recipient's responsibility 102 to acquire that license before distributing the Program. 103 104 d. Each Contributor represents that to its knowledge it has sufficient 105 copyright rights in its Contribution, if any, to grant the copyright 106 license set forth in this Agreement. 107 1083. REQUIREMENTS 109 110A. Distributor may choose to distribute the Program in any form under 111this Agreement or under its own license agreement, provided that: 112 113 a. it complies with the terms and conditions of this Agreement; 114 115 b. if the Program is distributed in source code or other tangible 116 form, a copy of this Agreement or Distributor's own license agreement 117 is included with each copy of the Program; and 118 119 c. if distributed under Distributor's own license agreement, such 120 license agreement: 121 122 i. effectively disclaims on behalf of all Contributors all warranties 123 and conditions, express and implied, including warranties or 124 conditions of title and non-infringement, and implied warranties or 125 conditions of merchantability and fitness for a particular purpose; 126 ii. effectively excludes on behalf of all Contributors all liability 127 for damages, including direct, indirect, special, incidental and 128 consequential damages, such as lost profits; and 129 iii. states that any provisions which differ from this Agreement are 130 offered by that Contributor alone and not by any other party. 131 132B. Each Distributor must include the following in a conspicuous 133 location in the Program: 134 135 Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights 136 Reserved. 137 138C. In addition, each Contributor must identify itself as the 139originator of its Contribution in a manner that reasonably allows 140subsequent Recipients to identify the originator of the Contribution. 141Also, each Contributor must agree that the additions and/or changes 142are intended to be a Contribution. Once a Contribution is contributed, 143it may not thereafter be revoked. 144 1454. COMMERCIAL DISTRIBUTION 146 147Commercial distributors of software may accept certain 148responsibilities with respect to end users, business partners and the 149like. While this license is intended to facilitate the commercial use 150of the Program, the Distributor who includes the Program in a 151commercial product offering should do so in a manner which does not 152create potential liability for Contributors. Therefore, if a 153Distributor includes the Program in a commercial product offering, 154such Distributor ("Commercial Distributor") hereby agrees to defend 155and indemnify every Contributor ("Indemnified Contributor") against 156any losses, damages and costs (collectively"Losses") arising from 157claims, lawsuits and other legal actions brought by a third party 158against the Indemnified Contributor to the extent caused by the acts 159or omissions of such Commercial Distributor in connection with its 160distribution of the Program in a commercial product offering. The 161obligations in this section do not apply to any claims or Losses 162relating to any actual or alleged intellectual property infringement. 163In order to qualify, an Indemnified Contributor must: a) promptly 164notify the Commercial Distributor in writing of such claim, and b) 165allow the Commercial Distributor to control, and cooperate with the 166Commercial Distributor in, the defense and any related settlement 167negotiations. The Indemnified Contributor may participate in any such 168claim at its own expense. 169 170For example, a Distributor might include the Program in a commercial 171product offering, Product X. That Distributor is then a Commercial 172Distributor. If that Commercial Distributor then makes performance 173claims, or offers warranties related to Product X, those performance 174claims and warranties are such Commercial Distributor's responsibility 175alone. Under this section, the Commercial Distributor would have to 176defend claims against the Contributors related to those performance 177claims and warranties, and if a court requires any Contributor to pay 178any damages as a result, the Commercial Distributor must pay those 179damages. 180 1815. NO WARRANTY 182 183EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS 184PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY 185KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY 186WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY 187OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely 188responsible for determining the appropriateness of using and 189distributing the Program and assumes all risks associated with its 190exercise of rights under this Agreement, including but not limited to 191the risks and costs of program errors, compliance with applicable 192laws, damage to or loss of data, programs or equipment, and 193unavailability or interruption of operations. 194 1956. DISCLAIMER OF LIABILITY 196 197EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR 198ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, 199INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING 200WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF 201LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING 202NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR 203DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED 204HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 205 2067. EXPORT CONTROL 207 208Recipient agrees that Recipient alone is responsible for compliance 209with the United States export administration regulations (and the 210export control laws and regulation of any other countries). 211 2128. GENERAL 213 214If any provision of this Agreement is invalid or unenforceable under 215applicable law, it shall not affect the validity or enforceability of 216the remainder of the terms of this Agreement, and without further 217action by the parties hereto, such provision shall be reformed to the 218minimum extent necessary to make such provision valid and enforceable. 219 220If Recipient institutes patent litigation against a Contributor with 221respect to a patent applicable to software (including a cross-claim or 222counterclaim in a lawsuit), then any patent licenses granted by that 223Contributor to such Recipient under this Agreement shall terminate as 224of the date such litigation is filed. In addition, if Recipient 225institutes patent litigation against any entity (including a 226cross-claim or counterclaim in a lawsuit) alleging that the Program 227itself (excluding combinations of the Program with other software or 228hardware) infringes such Recipient's patent(s), then such Recipient's 229rights granted under Section 2(b) shall terminate as of the date such 230litigation is filed. 231 232All Recipient's rights under this Agreement shall terminate if it 233fails to comply with any of the material terms or conditions of this 234Agreement and does not cure such failure in a reasonable period of 235time after becoming aware of such noncompliance. If all Recipient's 236rights under this Agreement terminate, Recipient agrees to cease use 237and distribution of the Program as soon as reasonably practicable. 238However, Recipient's obligations under this Agreement and any licenses 239granted by Recipient relating to the Program shall continue and 240survive. 241 242LUCENT may publish new versions (including revisions) of this 243Agreement from time to time. Each new version of the Agreement will be 244given a distinguishing version number. The Program (including 245Contributions) may always be distributed subject to the version of the 246Agreement under which it was received. In addition, after a new 247version of the Agreement is published, Contributor may elect to 248distribute the Program (including its Contributions) under the new 249version. No one other than LUCENT has the right to modify this 250Agreement. Except as expressly stated in Sections 2(a) and 2(b) above, 251Recipient receives no rights or licenses to the intellectual property 252of any Contributor under this Agreement, whether expressly, by 253implication, estoppel or otherwise. All rights in the Program not 254expressly granted under this Agreement are reserved. 255 256This Agreement is governed by the laws of the State of New York and 257the intellectual property laws of the United States of America. No 258party to this Agreement will bring a legal action under this Agreement 259more than one year after the cause of action arose. Each party waives 260its rights to a jury trial in any resulting litigation. 261 262
