    technical modifications necessary to exercise the Licensed Rights, including

    3(a)(1)(A)(i).

conditions.

        must: retain the following if it is supplied by the Licensor with the
        Licensed Material: identification of the creator(s) of the Licensed
        Material and any others designated to receive attribution, in any
        reasonable manner requested by the Licensor (including by pseudonym if

        License; a notice that refers to the disclaimer of warranties; a URI or
        hyperlink to the Licensed Material to the extent reasonably practicable;

        context in which You Share the Licensed Material. For example, it may be
        reasonable to satisfy the conditions by providing a URI or hyperlink to
        a resource that includes the required information.  If requested by the
        Licensor, You must remove any of the information required by Section
        3(a)(1)(A) to the extent reasonably practicable.  ShareAlike.

    In addition to the conditions in Section 3(a), if You Share Adapted Material
    You produce, the following conditions also apply.  The Adapter’s License You
    apply must be a Creative Commons license with the same License Elements,
    this version or later, or a BY-SA Compatible License.  You must include the
    text of, or the URI or hyperlink to, the Adapter's License You apply. You
    may satisfy this condition in any reasonable manner based on the medium,
    means, and context in which You Share Adapted Material.  You may not offer
    or impose any additional or different terms or conditions on, or apply any
    Effective Technological Measures to, Adapted Material that restrict exercise
    of the rights granted under the Adapter's License You apply.

Section 4 – Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your
use of the Licensed Material:

    for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
    reuse, reproduce, and Share all or a substantial portion of the contents of
    the database; if You include all or a substantial portion of the database
    contents in a database in which You have Sui Generis Database Rights, then
    the database in which You have Sui Generis Database Rights (but not its
    individual contents) is Adapted Material, including for purposes of Section
    3(b); and You must comply with the conditions in Section 3(a) if You Share
    all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your
obligations under this Public License where the Licensed Rights include other
Copyright and Similar Rights.

Section 5 – Disclaimer of Warranties and Limitation of Liability.

    Unless otherwise separately undertaken by the Licensor, to the extent
    possible, the Licensor offers the Licensed Material as-is and as-available,
    and makes no representations or warranties of any kind concerning the
    Licensed Material, whether express, implied, statutory, or other. This
    includes, without limitation, warranties of title, merchantability, fitness
    for a particular purpose, non-infringement, absence of latent or other
    defects, accuracy, or the presence or absence of errors, whether or not
    known or discoverable. Where disclaimers of warranties are not allowed in
    full or in part, this disclaimer may not apply to You.  To the extent
    possible, in no event will the Licensor be liable to You on any legal theory
    (including, without limitation, negligence) or otherwise for any direct,
    special, indirect, incidental, consequential, punitive, exemplary, or other
    losses, costs, expenses, or damages arising out of this Public License or
    use of the Licensed Material, even if the Licensor has been advised of the
    possibility of such losses, costs, expenses, or damages. Where a limitation
    of liability is not allowed in full or in part, this limitation may not
    apply to You.

    The disclaimer of warranties and limitation of liability provided above
    shall be interpreted in a manner that, to the extent possible, most closely
    approximates an absolute disclaimer and waiver of all liability.

Section 6 – Term and Termination.

    This Public License applies for the term of the Copyright and Similar Rights
    licensed here. However, if You fail to comply with this Public License, then
    Your rights under this Public License terminate automatically.

    Where Your right to use the Licensed Material has terminated under Section
    6(a), it reinstates: automatically as of the date the violation is cured,
    provided it is cured within 30 days of Your discovery of the violation; or
    upon express reinstatement by the Licensor.  For the avoidance of doubt,
    this Section 6(b) does not affect any right the Licensor may have to seek
    remedies for Your violations of this Public License.  For the avoidance of
    doubt, the Licensor may also offer the Licensed Material under separate
    terms or conditions or stop distributing the Licensed Material at any time;
    however, doing so will not terminate this Public License.  Sections 1, 5, 6,
    7, and 8 survive termination of this Public License.

Section 7 – Other Terms and Conditions.

    The Licensor shall not be bound by any additional or different terms or
    conditions communicated by You unless expressly agreed.  Any arrangements,
    understandings, or agreements regarding the Licensed Material not stated
    herein are separate from and independent of the terms and conditions of this
    Public License.

Section 8 – Interpretation.

    For the avoidance of doubt, this Public License does not, and shall not be
    interpreted to, reduce, limit, restrict, or impose conditions on any use of
    the Licensed Material that could lawfully be made without permission under
    this Public License.  To the extent possible, if any provision of this
    Public License is deemed unenforceable, it shall be automatically reformed
    to the minimum extent necessary to make it enforceable. If the provision
    cannot be reformed, it shall be severed from this Public License without
    affecting the enforceability of the remaining terms and conditions.  No term
    or condition of this Public License will be waived and no failure to comply
    consented to unless expressly agreed to by the Licensor.  Nothing in this
    Public License constitutes or may be interpreted as a limitation upon, or
    waiver of, any privileges and immunities that apply to the Licensor or You,
    including from the legal processes of any jurisdiction or authority.
