Article 4

1. (a)    Contracting Parties shall provide in their national copyright laws for a limitation or exception to the right of reproduction, the right of distribution, and the right of making available to the public as provided by the WIPO Copyright Treaty (WCT), to facilitate the availability of works in accessible format copies for beneficiary persons. The limitation or exception provided in national law should permit changes needed to make the work accessible in the alternative format.
(b) Contracting Parties may also provide a limitation or exception to the right of public performance to facilitate access to works for beneficiary persons.

2. A Contracting Party may fulfill Article 4(1) for all rights identified therein by providing a limitation or exception in its national copyright law such that:
(a) authorized entities shall be permitted, without the authorization of the copyright rightholder, to make an accessible format copy of a work, obtain from another authorized entity an accessible format copy, and supply those copies to beneficiary persons by any means, including by non-commercial lending or by electronic communication by wire or wireless means, and undertake any intermediate steps to achieve those objectives, when all of the following conditions are met:
(i) the authorized entity wishing to undertake said activity has lawful access to that work or a copy of that work;
(ii) the work is converted to an accessible format copy, which may include any means needed to navigate information in the accessible format, but does not introduce changes other than those needed to make the work accessible to the beneficiary person;
(iii) such accessible format copies are supplied exclusively to be used by beneficiary persons; and
(iv) the activity is undertaken on a non-profit basis;
and
(b) a beneficiary person, or someone acting on his or her behalf including a primary caretaker or caregiver, may make an accessible format copy of a work for the personal use of the beneficiary person or otherwise may assist the beneficiary person to make and use accessible format copies where the beneficiary person has lawful access to that work or a copy of that work.

3. A Contracting Party may fulfill Article 4(1) by providing other limitations or exceptions in its national copyright law pursuant to Articles 10 and 11 (4).

4. A Contracting Party may confine limitations or exceptions under this Article to works which, in the particular accessible format, cannot be obtained commercially under reasonable terms for beneficiary persons in that market. Any Contracting Party availing itself of this possibility shall so declare in a notification deposited with the Director-General of WIPO at the time of ratification of, acceptance of or accession to this Treaty or at any time thereafter (5).

5.It shall be a matter for national law to determine whether limitations or exceptions under this Article are subject to remuneration.
