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.

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.

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/.
