| 41 | 1. DEFINITIONS | ||
| 42 | |||
| 43 | A. "Contributor" means Government Agency, as the developer of the Original Software, and any entity | ||
| 44 | that makes a Modification. | ||
| 45 | |||
| 46 | B. "Covered Patents" mean patent claims licensable by a Contributor that are necessarily infringed by | ||
| 47 | the use or sale of its Modification alone or when combined with the Subject Software. | ||
| 48 | |||
| 49 | C. "Display" means the showing of a copy of the Subject Software, either directly or by means of an | ||
| 50 | image, or any other device. | ||

| 59 | structure of either the Original Software or Subject Software, and includes derivative works, as that | ||
| 60 | term is defined in the Copyright Statute, 17 USC � 101. However, the act of including Subject Software | ||
| 61 | as part of a Larger Work does not in and of itself constitute a Modification. | ||
| 62 | |||
| 63 | G. "Original Software" means the computer software first released under this Agreement by Government | ||
| 64 | Agency entitled openPDC, including source code, object code and accompanying documentation, if any. | ||

| 79 | 2. GRANT OF RIGHTS | ||
| 80 | |||
| 81 | A. Under Non-Patent Rights: Subject to the terms and conditions of this Agreement, each Contributor, | ||
| 82 | with respect to its own contribution to the Subject Software, hereby grants to each Recipient a | ||
| 83 | non-exclusive, world-wide, royalty-free license to engage in the following activities pertaining to | ||

| 113 | C. The rights granted under Paragraph B. also apply to the combination of a Contributor's Modification | ||
| 114 | and the Subject Software if, at the time the Modification is added by the Contributor, the addition of | ||
| 115 | such Modification causes the combination to be covered by the Covered Patents. It does not apply to | ||
| 116 | any other combinations that include a Modification. | ||
| 117 | |||
| 118 | D. The rights granted in Paragraphs A. and B. allow the Recipient to sublicense those same rights. | ||
| 119 | Such sublicense must be under the same terms and conditions of this Agreement. | ||
| 120 | |||
| 121 | 3. OBLIGATIONS OF RECIPIENT | ||
| 122 | |||
| 123 | A. Distribution or Redistribution of the Subject Software must be made under this Agreement except for | ||
| 124 | additions covered under paragraph 3H. | ||
| 125 | |||
| 126 | 1. Whenever a Recipient distributes or redistributes the Subject Software, a copy of this Agreement | ||
| 127 | must be included with each copy of the Subject Software; and | ||
| 128 | |||
| 129 | 2. If Recipient distributes or redistributes the Subject Software in any form other than source code, | ||
| 130 | Recipient must also make the source code freely available, and must provide with each copy of the | ||
| 131 | Subject Software information on how to obtain the source code in a reasonable manner on or through a | ||
| 132 | medium customarily used for software exchange. | ||
| 133 | |||
| 134 | B. Each Recipient must ensure that the following copyright notice appears prominently in the Subject | ||
| 135 | Software: | ||
| 136 | |||
| 137 | No copyright is claimed pursuant to 17 USC � 105. All Other Rights Reserved. | ||
| 138 | |||
| 139 | C. Each Contributor must characterize its alteration of the Subject Software as a Modification and | ||
| 140 | must identify itself as the originator of its Modification in a manner that reasonably allows | ||
| 141 | subsequent Recipients to identify the originator of the Modification. In fulfillment of these | ||
| 142 | requirements, Contributor must include a file (e.g., a change log file) that describes the alterations | ||
| 143 | made and the date of the alterations, identifies Contributor as originator of the alterations, and | ||
| 144 | consents to characterization of the alterations as a Modification, for example, by including a | ||
| 145 | statement that the Modification is derived, directly or indirectly, from Original Software provided by | ||
| 146 | Government Agency. Once consent is granted, it may not thereafter be revoked. | ||
| 147 | |||
| 148 | D. A Contributor may add its own copyright notice to the Subject Software. Once a copyright notice has | ||
| 149 | been added to the Subject Software, a Recipient may not remove it without the express permission of | ||
| 150 | the Contributor who added the notice. | ||
| 151 | |||
| 152 | E. A Recipient may not make any representation in the Subject Software or in any promotional, | ||
| 153 | advertising or other material that may be construed as an endorsement by Government Agency or by any | ||
| 154 | prior Recipient of any product or service provided by Recipient, or that may seek to obtain commercial | ||
| 155 | advantage by the fact of Government Agency's or a prior Recipient's participation in this Agreement. | ||
| 156 | |||
| 157 | F. In an effort to track usage and maintain accurate records of the Subject Software, each Recipient, | ||
| 158 | upon receipt of the Subject Software, is requested to register with Government Agency by visiting the | ||
| 159 | following website: https://naspi.tva.com/Registration/. Recipient's name and personal information | ||
| 160 | shall be used for statistical purposes only. Once a Recipient makes a Modification available, it is | ||
| 161 | requested that the Recipient inform Government Agency at the web site provided above how to access the | ||
| 162 | Modification. | ||
| 163 | |||
| 164 | G. Each Contributor represents that that its Modification does not violate any existing agreements, | ||
| 165 | regulations, statutes or rules, and further that Contributor has sufficient rights to grant the rights | ||
| 166 | conveyed by this Agreement. | ||
| 167 | |||
| 168 | H. A Recipient may choose to offer, and to charge a fee for, warranty, support, indemnity and/or | ||
| 169 | liability obligations to one or more other Recipients of the Subject Software. A Recipient may do so, | ||
| 170 | however, only on its own behalf and not on behalf of Government Agency or any other Recipient. Such a | ||
| 171 | Recipient must make it absolutely clear that any such warranty, support, indemnity and/or liability | ||
| 172 | obligation is offered by that Recipient alone. Further, such Recipient agrees to indemnify Government | ||
| 173 | Agency and every other Recipient for any liability incurred by them as a result of warranty, support, | ||
| 174 | indemnity and/or liability offered by such Recipient. | ||
| 175 | |||
| 176 | I. A Recipient may create a Larger Work by combining Subject Software with separate software not | ||
| 177 | governed by the terms of this agreement and distribute the Larger Work as a single product. In such | ||
| 178 | case, the Recipient must make sure Subject Software, or portions thereof, included in the Larger Work | ||
| 179 | is subject to this Agreement. | ||
| 180 | |||
| 181 | J. Notwithstanding any provisions contained herein, Recipient is hereby put on notice that export of | ||
| 182 | any goods or technical data from the United States may require some form of export license from the | ||
| 183 | U.S. Government. Failure to obtain necessary export licenses may result in criminal liability under | ||
| 184 | U.S. laws. Government Agency neither represents that a license shall not be required nor that, if | ||
| 185 | required, it shall be issued. Nothing granted herein provides any such export license. | ||
| 186 | |||
| 187 | 4. DISCLAIMER OF WARRANTIES AND LIABILITIES; WAIVER AND INDEMNIFICATION | ||
| 188 | |||
| 189 | A. No Warranty: THE SUBJECT SOFTWARE IS PROVIDED "AS IS" WITHOUT ANY WARRANTY OF ANY KIND, EITHER | ||
| 190 | EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY THAT THE SUBJECT | ||
| 191 | SOFTWARE WILL CONFORM TO SPECIFICATIONS, ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A | ||
| 192 | PARTICULAR PURPOSE, OR FREEDOM FROM INFRINGEMENT, ANY WARRANTY THAT THE SUBJECT SOFTWARE WILL BE ERROR | ||
| 193 | FREE, OR ANY WARRANTY THAT DOCUMENTATION, IF PROVIDED, WILL CONFORM TO THE SUBJECT SOFTWARE. THIS | ||
| 194 | AGREEMENT DOES NOT, IN ANY MANNER, CONSTITUTE AN ENDORSEMENT BY GOVERNMENT AGENCY OR ANY PRIOR | ||

| 196 | RESULTING FROM USE OF THE SUBJECT SOFTWARE. FURTHER, GOVERNMENT AGENCY DISCLAIMS ALL WARRANTIES AND | ||
| 197 | LIABILITIES REGARDING THIRD-PARTY SOFTWARE, IF PRESENT IN THE ORIGINAL SOFTWARE, AND DISTRIBUTES IT | ||
| 198 | "AS IS." | ||
| 199 | |||
| 200 | B. Waiver and Indemnity: RECIPIENT AGREES TO WAIVE ANY AND ALL CLAIMS AGAINST GOVERNMENT AGENCY, ITS | ||
| 201 | AGENTS, EMPLOYEES, CONTRACTORS AND SUBCONTRACTORS, AS WELL AS ANY PRIOR RECIPIENT. IF RECIPIENT'S USE | ||
| 202 | OF THE SUBJECT SOFTWARE RESULTS IN ANY LIABILITIES, DEMANDS, DAMAGES, EXPENSES OR LOSSES ARISING FROM | ||
| 203 | SUCH USE, INCLUDING ANY DAMAGES FROM PRODUCTS BASED ON, OR RESULTING FROM, RECIPIENT'S USE OF THE | ||
| 204 | SUBJECT SOFTWARE, RECIPIENT SHALL INDEMNIFY AND HOLD HARMLESS GOVERNMENT AGENCY, ITS AGENTS, | ||
| 205 | EMPLOYEES, CONTRACTORS AND SUBCONTRACTORS, AS WELL AS ANY PRIOR RECIPIENT, TO THE EXTENT PERMITTED BY | ||
| 206 | LAW. THE FOREGOING RELEASE AND INDEMNIFICATION SHALL APPLY EVEN IF THE LIABILITIES, DEMANDS, DAMAGES, | ||
| 207 | EXPENSES OR LOSSES ARE CAUSED, OCCASIONED, OR CONTRIBUTED TO BY THE NEGLIGENCE, SOLE OR CONCURRENT, OF | ||
| 208 | GOVERNMENT AGENCY OR ANY PRIOR RECIPIENT. RECIPIENT'S SOLE REMEDY FOR ANY SUCH MATTER SHALL BE THE | ||
| 209 | IMMEDIATE, UNILATERAL TERMINATION OF THIS AGREEMENT. | ||
