Section 2.2. The Source Code version of Covered Code may be distributed
only under the terms of this License or a future version of this
License released under Section 6.1, and You must include a copy of this
License with every copy of the Source Code You distribute. You may not
offer or impose any terms on any Source Code version that alters or
restricts the applicable version of this License or the recipients'
rights hereunder. However, You may include an additional document
offering the additional rights described in Section 3.5.
- 3.2. Availability of Source Code.
Any Modification which You create or to which You contribute must be
made available in Source Code form under the terms of this License
either on the same media as an Executable version or via an accepted
Electronic Distribution Mechanism to anyone to whom you made an
Executable version available; and if made available via Electronic
Distribution Mechanism, must remain available for at least twelve (12)
months after the date it initially became available, or at least six
(6) months after a subsequent version of that particular Modification
has been made available to such recipients. You are responsible for
ensuring that the Source Code version remains available even if the
Electronic Distribution Mechanism is maintained by a third party.
- 3.3. Description of Modifications.
You must cause all Covered Code to which You contribute to contain a
file documenting the changes You made to create that Covered Code and
the date of any change. You must include a prominent statement that the
Modification is derived, directly or indirectly, from Original Code
provided by the Initial Developer and including the name of the Initial

Executable version or related documentation in which You describe the
origin or ownership of the Covered Code.
- 3.4. Intellectual Property Matters
- (a) Third Party Claims.
If Contributor has knowledge that a license under a third party's
intellectual property rights is required to exercise the rights granted
by such Contributor under Sections 2.1 or 2.2, Contributor must include
a text file with the Source Code distribution titled "LEGAL" which
describes the claim and the party making the claim in sufficient detail
that a recipient will know whom to contact. If Contributor obtains such
knowledge after the Modification is made available as described in
Section 3.2, Contributor shall promptly modify the LEGAL file in all
copies Contributor makes available thereafter and shall take other
steps (such as notifying appropriate mailing lists or newsgroups)
reasonably calculated to inform those who received the Covered Code
that new knowledge has been obtained.
- (b) Contributor APIs.
If Contributor's Modifications include an application programming
interface and Contributor has knowledge of patent licenses which are
reasonably necessary to implement that API, Contributor must also
include this information in the LEGAL file.
- (c) Representations.
Contributor represents that, except as disclosed pursuant to Section
3.4(a) above, Contributor believes that Contributor's Modifications are
Contributor's original creation(s) and/or Contributor has sufficient
rights to grant the rights conveyed by this License.

You must duplicate the notice in Exhibit A in each file of the Source
Code. If it is not possible to put such notice in a particular Source
Code file due to its structure, then You must include such notice in a
location (such as a relevant directory) where a user would be likely to
look for such a notice. If You created one or more Modification(s) You
may add your name as a Contributor to the notice described in Exhibit
A. You must also duplicate this License in any documentation for the
Source Code where You describe recipients' rights or ownership rights
relating to Covered Code. You may choose to offer, and to charge a fee
for, warranty, support, indemnity or liability obligations to one or
more recipients of Covered Code. However, You may do so only on Your
own behalf, and not on behalf of the Initial Developer or any
Contributor. You must make it absolutely clear than any such warranty,
support, indemnity or liability obligation is offered by You alone, and
You hereby agree to indemnify the Initial Developer and every
Contributor for any liability incurred by the Initial Developer or such
Contributor as a result of warranty, support, indemnity or liability
terms You offer.
- 3.6. Distribution of Executable Versions.
You may distribute Covered Code in Executable form only if the
requirements of Section 3.1-3.5 have been met for that Covered Code,
and if You include a notice stating that the Source Code version of the
Covered Code is available under the terms of this License, including a
description of how and where You have fulfilled the obligations of
Section 3.2. The notice must be conspicuously included in any notice in
an Executable version, related documentation or collateral in which You
describe recipients' rights relating to the Covered Code. You may
distribute the Executable version of Covered Code or ownership rights
under a license of Your choice, which may contain terms different from
this License, provided that You are in compliance with the terms of
this License and that the license for the Executable version does not
attempt to limit or alter the recipient's rights in the Source Code
version from the rights set forth in this License. If You distribute
the Executable version under a different license You must make it
absolutely clear that any terms which differ from this License are
offered by You alone, not by the Initial Developer or any Contributor.
You hereby agree to indemnify the Initial Developer and every
Contributor for any liability incurred by the Initial Developer or such
Contributor as a result of any such terms You offer.

of this License to the maximum extent possible; and (b) describe the
limitations and the code they affect. Such description must be included
in the LEGAL file described in Section 3.4 and must be included with
all distributions of the Source Code. Except to the extent prohibited
by statute or regulation, such description must be sufficiently
detailed for a recipient of ordinary skill to be able to understand it.

of any subsequent version of the License published by Zimbra. No one
other than Zimbra has the right to modify the terms applicable to
Covered Code created under this License.
- 6.3. Derivative Works.
If You create or use a modified version of this License (which you may
only do in order to apply it to code which is not already Covered Code
governed by this License), You must (a) rename Your license so that the
phrases "Zimbra", "ZPL" or any confusingly similar phrase do not appear
in your license (except to note that your license differs from this
License) and (b) otherwise make it clear that Your version of the
license contains terms which differ from the Zimbra Public License.

- 7. DISCLAIMER OF WARRANTY.
CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT
LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS,
MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE
ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS
WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU
(NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF
ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF
WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY

such breach within 30 days of becoming aware of the breach. All
sublicenses to the Covered Code which are properly granted shall
survive any termination of this License. Provisions which, by their
nature, must remain in effect beyond the termination of this License
If You initiate litigation by asserting a patent infringement claim
(excluding declatory judgment actions) against Initial Developer or a
Contributor (the Initial Developer or Contributor against whom You file
such action is referred to as "Participant") alleging that:
such Participant's Contributor Version directly or indirectly infringes
any patent, then any and all rights granted by such Participant to You
under Sections 2.1 and/or 2.2 of this License shall, upon 60 days
notice from Participant terminate prospectively, unless if within 60
days after receipt of notice You either: (i) agree in writing to pay
Participant a mutually agreeable reasonable royalty for Your past and
future use of Modifications made by such Participant, or (ii) withdraw
Your litigation claim with respect to the Contributor Version against
such Participant. If within 60 days of notice, a reasonable royalty and
payment arrangement are not mutually agreed upon in writing by the
parties or the litigation claim is not withdrawn, the rights granted by
Participant to You under Sections 2.1 and/or 2.2 automatically
terminate at the expiration of the 60 day notice period specified
any software, hardware, or device, other than such Participant's
Contributor Version, directly or indirectly infringes any patent, then
any rights granted to You by such Participant under Sections 2.1(b) and
2.2(b) are revoked effective as of the date You first made, used, sold,
distributed, or had made, Modifications made by that Participant.
If You assert a patent infringement claim against Participant alleging
that such Participant's Contributor Version directly or indirectly
infringes any patent where such claim is resolved (such as by license
or settlement) prior to the initiation of patent infringement
litigation, then the reasonable value of the licenses granted by such
Participant under Sections 2.1 or 2.2 shall be taken into account in
determining the amount or value of any payment or license.
In the event of termination under Sections 8.1 or 8.2 above, all
end-user license agreements (excluding distributors and resellers)
which have been validly granted by You or any distributor hereunder
prior to termination shall survive termination.

NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING
NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER,
ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY
SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY
INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS
EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
