"Contributor" means Government Agency, as the developer of the Original Software, and any entity that makes a Modification. B. "Covered Patents" mean patent claims licensable by a Contributor that are necessarily infringed by the use or sale of its Modification alone or when combined with the Subject Software. C. "Display" means the showing of a copy of the Subject Software, either directly or by means of an image, or any other device. D. "Distribution" means conveyance or transfer of the Subject Software, regardless of means, to another. E. "Larger Work" means computer software that combines Subject Software, or portions thereof, with software separate from the Subject Software that is not governed by the terms of this Agreement. F. "Modification" means any alteration of, including addition to or deletion from, the substance or structure of either the Original Software or Subject Software, and includes derivative works, as that term is defined in the Copyright Statute, 17 USC § 101. However, the act of including Subject Software as part of a Larger Work does not in and of itself constitute a Modification. G. "Original Software" means the computer software first released under this Agreement by Government Agency entitled openPDC, including source code, object code and accompanying documentation, if any. H. "Recipient" means anyone who acquires the Subject Software under this Agreement, including all Contributors. I. "Redistribution" means Distribution of the Subject Software after a Modification has been made. J. "Reproduction" means the making of a counterpart, image or copy of the Subject Software. K. "Sale" means the exchange of the Subject Software for money or equivalent value. L. "Subject Software" means the Original Software, Modifications, or any respective parts thereof. M. "Use" means the application or employment of the Subject Software for any purpose. 2. GRANT OF RIGHTS A. Under Non-Patent Rights: Subject to the terms and conditions of this Agreement, each Contributor, with respect to its own contribution to the Subject Software, hereby grants to each Recipient a non-exclusive, world-wide, royalty-free license to engage in the following activities pertaining to the Subject Software: 1. Use 2. Distribution 3. Reproduction 4. Modification 5. Redistribution 6. Display B. Under Patent Rights: Subject to the terms and conditions of this Agreement, each Contributor, with respect to its own contribution to the Subject Software, hereby grants to each Recipient under Covered Patents a non-exclusive, world-wide, royalty-free license to engage in the following activities pertaining to the Subject Software: 1. Use 2. Distribution 3. Reproduction 4. Sale 5. Offer for Sale C. The rights granted under Paragraph B. also apply to the combination of a Contributor's Modification and the Subject Software if, at the time the Modification is added by the Contributor, the addition of such Modification causes the combination to be covered by the Covered Patents. It does not apply to any other combinations that include a Modification. D. The rights granted in Paragraphs A. and B. allow the Recipient to sublicense those same rights. Such sublicense must be under the same terms and conditions of this Agreement. 3. OBLIGATIONS OF RECIPIENT A. Distribution or Redistribution of the Subject Software must be made under this Agreement except for additions covered under paragraph 3H. 1. Whenever a Recipient distributes or redistributes the Subject Software, a copy of this Agreement must be included with each copy of the Subject Software; and 2. If Recipient distributes or redistributes the Subject Software in any form other than source code, Recipient must also make the source code freely available, and must provide with each copy of the Subject Software information on how to obtain the source code in a reasonable manner on or through a medium customarily used for software exchange. B. Each Recipient must ensure that the following copyright notice appears prominently in the Subject Software: No copyright is claimed pursuant to 17 USC § 105. All Other Rights Reserved. C. Each Contributor must characterize its alteration of the Subject Software as a Modification and must identify itself as the originator of its Modification in a manner that reasonably allows subsequent Recipients to identify the originator of the Modification. In fulfillment of these requirements, Contributor must include a file (e.g., a change log file) that describes the alterations made and the date of the alterations, identifies Contributor as originator of the alterations, and consents to characterization of the alterations as a Modification, for example, by including a statement that the Modification is derived, directly or indirectly, from Original Software provided by Government Agency. Once consent is granted, it may not thereafter be revoked. D. A Contributor may add its own copyright notice to the Subject Software. Once a copyright notice has been added to the Subject Software, a Recipient may not remove it without the express permission of the Contributor who added the notice. E. A Recipient may not make any representation in the Subject Software or in any promotional, advertising or other material that may be construed as an endorsement by Government Agency or by any prior Recipient of any product or service provided by Recipient, or that may seek to obtain commercial advantage by the fact of Government Agency's or a prior Recipient's participation in this Agreement. F. In an effort to track usage and maintain accurate records of the Subject Software, each Recipient, upon receipt of the Subject Software, is requested to register with Government Agency by visiting the following website: https://naspi.tva.com/Registration/. Recipient's name and personal information shall be used for statistical purposes only. Once a Recipient makes a Modification available, it is requested that the Recipient inform Government Agency at the web site provided above how to access the Modification. G. Each Contributor represents that that its Modification does not violate any existing agreements, regulations, statutes or rules, and further that Contributor has sufficient rights to grant the rights conveyed by this Agreement. H. A Recipient may choose to offer, and to charge a fee for, warranty, support, indemnity and/or liability obligations to one or more other Recipients of the Subject Software. A Recipient may do so, however, only on its own behalf and not on behalf of Government Agency or any other Recipient. Such a Recipient must make it absolutely clear that any such warranty, support, indemnity and/or liability obligation is offered by that Recipient alone. Further, such Recipient agrees to indemnify Government Agency and every other Recipient for any liability incurred by them as a result of warranty, support, indemnity and/or liability offered by such Recipient. I. A Recipient may create a Larger Work by combining Subject Software with separate software not governed by the terms of this agreement and distribute the Larger Work as a single product. In such case, the Recipient must make sure Subject Software, or portions thereof, included in the Larger Work is subject to this Agreement. J. Notwithstanding any provisions contained herein, Recipient is hereby put on notice that export of any goods or technical data from the United States may require some form of export license from the U.S. Government. Failure to obtain necessary export licenses may result in criminal liability under U.S. laws.
