aggregate software distribution does not invalidate, weaken,
restrict, interpret, amend, modify, interfere with or otherwise
affect any part, term, provision, or clause of this License) or
any respective part(s) thereof.

5. "Distribution" means (and "distribute" refers to), regardless
of means or methods, conveyance, transfer, providing, or making
available of This/Your Product or portions thereof to third
parties (including, but not limited to, making This/Your

II. Terms and Conditions for Use, Copying, and Distribution

1. You may copy and/or distribute This Product, provided that
You do not modify This Product (for terms and conditions for
copying and distribution of modified versions of This Product,
see Chapter III) and provided that You do not include This
Product in another product forming Your Product (except as
permitted under Chapter III), and provided that You ensure that
all the legal notices and documents (containing, e.g., the text
of this License, references to this License, etc.) included with
This Product are included with every copy of This Product that
You make and distribute, and provided that You comply with all
other applicable terms and conditions of this License.

2. Provided that You comply with all applicable terms and
conditions of this License, You may use This Product freely (see
also Chapter III) on any number of computers/systems for non-
commercial and/or commercial purposes.



III. Terms and Conditions for Modification and Derivation of New
Products

1. If all conditions specified in the following paragraphs in
this Chapter (III) are met (for exceptions, see Section III.2)
and if You comply with all other applicable terms and conditions
of this License, You may modify This Product (thus forming Your
Product), derive new works from This Product or portions thereof
(thus forming Your Product), include This Product or portions
thereof in another product (thus forming Your Product, unless
defined otherwise in Chapter I), and You may use (for non-
commercial and/or commercial purposes), copy, and/or distribute
Your Product.

    a. The name of Your Product (or of Your modified version of
    This Product) must not contain the name TrueCrypt (for
    example, the following names are not allowed: TrueCrypt,
    TrueCrypt+, TrueCrypt Professional, iTrueCrypt, etc.) nor
    any other names confusingly similar to the name TrueCrypt
    (e.g., True-Crypt, True Crypt, TruKrypt, etc.)

    Note: TrueCrypt and the TrueCrypt logos are trademarks of
    the TrueCrypt Foundation. The goal is not to monetize the
    name or the product, but to protect the reputation of
    TrueCrypt, and to prevent support issues and other kinds of
    issues that might arise from the existence of similar
    products with the same or similar name. Even though
    TrueCrypt and the TrueCrypt logos are trademarks, TrueCrypt
    is and will remain open-source and free software.

    All occurrences of the name TrueCrypt that could reasonably
    be considered to identify Your Product must be removed from
    Your Product and from any associated materials. Logo(s)
    included in (or attached to) Your Product (and in/to
    associated materials) must not incorporate and must not be
    confusingly similar to any of the TrueCrypt logos (including
    the non-textual logo consisting primarily of a key in
    stylized form) or portion(s) thereof. All graphics contained
    in This Product (logos, icons, etc.) must be removed from
    Your Product (or from Your modified version of This Product)
    and from any associated materials.

    b. The following phrases must be removed from Your Product
    and from any associated materials, except the text of this
    License: "A TrueCrypt Foundation Release", "Released by
    TrueCrypt Foundation", "This is a TrueCrypt Foundation
    release."

    c. Phrase "Based on TrueCrypt, freely available at
    http://www.truecrypt.org/" must be displayed by Your Product
    (if technically feasible) and contained in its
    documentation. Alternatively, if This Product or its portion
    You included in Your Product constitutes only a minor
    portion of Your Product, phrase "Portions of this product
    are based in part on TrueCrypt, freely available at
    http://www.truecrypt.org/" may be displayed instead. In each
    of the cases mentioned above in this paragraph,
    "http://www.truecrypt.org/" must be a hyperlink (if
    technically feasible) pointing to http://www.truecrypt.org/
    and You may freely choose the location within the user
    interface (if there is any) of Your Product (e.g., an
    "About" window, etc.) and the way in which Your Product will
    display the respective phrase.

    Your Product (and any associated materials, e.g., the
    documentation, the content of the official web site of Your
    Product, etc.) must not present any Internet address
    containing the domain name truecrypt.org (or any domain name
    that forwards to the domain name truecrypt.org) in a manner
    that might suggest that it is where information about Your
    Product may be obtained or where bugs found in Your Product
    may be reported or where support for Your Product may be
    available or otherwise attempt to indicate that the domain
    name truecrypt.org is associated with Your Product.

    d. The complete source code of Your Product must be freely
    and publicly available (for exceptions, see Section III.2)
    at least until You cease to distribute Your Product and
    there must be a well-publicized means of obtaining the
    source code free of charge or for a reasonable reproduction
    fee (at least until You cease to distribute Your Product).
    Examples of possible ways to meet these conditions: (i) You
    include the source code with every copy of Your Product that
    You make and distribute (see also below in this Subsection
    III.1.d for conditions that licenses governing the source
    code must meet) provided that You make the copies available
    to the general public free of charge or for a reasonable
    reproduction fee, or (ii) You include information (valid and
    correct at least until You cease to distribute Your Product)
    about where the source code can be freely obtained (e.g., an
    Internet address, etc.) with every copy of Your Product that
    You make and distribute (see also below in this Subsection
    III.1.d for conditions that licenses governing the source
    code must meet) provided that You make the copies available
    to the general public free of charge or for a reasonable
    reproduction fee.

    Portions of the source code that were created by You (e.g.
    Your additions to This Product) must be available under
    license(s) that are/is compatible with this version of the
    TrueCrypt License (however, see also Subsection III.1.e) and
    that allow(s) anyone to modify and derive new works from the
    portions of the source code that were created by You and to
    use, copy, and redistribute such modifications and/or
    derivative works. The license(s) must be perpetual, non-
    exclusive, royalty-free, no-charge, and worldwide, and must
    not invalidate, weaken, restrict, interpret, amend, modify,
    interfere with or otherwise affect any part, term,
    provision, or clause of this License. The text of the
    license(s) must be included with every copy of Your Product
    that You make and distribute. The source code must not be
    deliberately obfuscated, and it must not be in an
    intermediate form (e.g., the output of a preprocessor).
    Source code means the preferred form in which a programmer
    would usually modify the program.

    Note: If you cannot comply with the above requirements, we
    may grant an exception under certain conditions. You may
    request an exception at: [e-mail]

    e. You must not change the license terms of This Product in
    any way (adding any new terms is considered changing the
    license terms even if the original terms are retained),
    which means, e.g., that no part of This Product may be put
    under another license. You must keep intact all the legal
    notices contained in the source code files. You must include
    the following items with every copy of Your Product that You
    make and distribute: a clear and conspicuous notice stating
    that Your Product or portion(s) thereof is/are governed by
    this version of the TrueCrypt License, a verbatim copy of
    this version of the TrueCrypt License (as contained herein),
    a clear and conspicuous notice containing information about
    where the included copy of the License can be found, and an
    appropriate copyright notice.


2. You are not obligated to comply with Subsection III.1.d if
Your Product is not distributed (i.e., Your Product is available
only to You).

Note: If you cannot comply with Subsection III.1.d, we may grant
an exception under certain conditions. You may request an
exception at: [e-mail]
