Paragraph 2 creates a similar exemption for distance learning. A work may be performed or displayed through transmission to students enrolled in a course, or to government employees as part of their duties, without requiring a performance license. The exemption does not apply to works produced and sold for online distance learning. The performance or display must be made under the direction of the instructor and directly related to, and in aid of, what is being taught: it cannot be used as a pretext for transmission of other works. Nondramatic literary or musical works may be performed in their entirety. For other works, such as display of a film or painting, the performance must be "reasonable and limited." The exemption applies only to distance learning that is part of scheduled classes. Works that are simply posted by an instructor would not be protected. The educational institution must meet certain additional conditions. It must provide information to faculty, students, and relevant staff members describing US copyright law and promoting compliance. For digital transmissions, the institution must take reasonable steps to prevent unauthorized retention or further distribution of copies of the work such as not interfering with any technological means the copyright owner may have used to prevent copying.
