THE OPEN GROUP PUBLIC LICENSE
MOTIF GRAPHICAL USER INTERFACE SOFTWARE

THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS THE OPEN
GROUP PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR
DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS
AGREEMENT.

1. DEFINITIONS

   "Contribution" means:

      1. in the case of The Open Group, L.L.C. ("The Open Group"),
      the Original Program, and

      2. in the case of each Contributor,

         i.  changes to the Program, and
         ii. additions to the Program;

      where such changes and/or additions to the Program originate
      from and are distributed by that particular Contributor.
      A Contribution 'originates' from a Contributor if it was added
      to the Program by such Contributor itself or anyone acting on
      such Contributor's behalf. Contributions do not include additions
      to the Program which:

         i.  are separate modules of software distributed in conjunction
         with the Program under their own license agreement, even if
         the separate modules are linked in binary form to the Program,
         and

         ii. are not derivative works of the Program.

 
   "Contributor" means The Open Group and any other entity that
   distributes the Program.

   "Licensed Patents" mean patent claims licensable by a Contributor
   which are necessarily infringed by the use or sale of its Contribution
   alone or when combined with the Program.

   "Open Source" programs mean software for which the source code is
   available without confidential or trade secret restrictions and for
   which the source code and object code are available for distribution
   without license charges.

   "Original Program" means the original version of the software
   accompanying this Agreement as released by The Open Group,
   including source code, object code and documentation, if any.

   "Program" means the Original Program and Contributions.

   "Recipient" means anyone who receives the Program under this
   Agreement, including all Contributors.


2. GRANT OF RIGHTS

   The rights granted under this license are limited solely to
   distribution and sublicensing of the Contribution(s) on, with, or
   for operating systems which are themselves Open Source programs.
   Contact The Open Group for a license allowing distribution and
   sublicensing of the Original Program on, with, or for operating
   systems which are not Open Source programs.

   1. Subject to the terms of this Agreement and the limitations of
   this Section 2, each Contributor hereby grants Recipient a
   non-exclusive, worldwide, royalty-free copyright license to
   reproduce, prepare derivative works of, publicly display, publicly
   perform, distribute and sublicense the Contribution of such
   Contributor, if any, and such derivative works, in source code and
   object code form.

   2.  Subject to the terms of this Agreement and the limitations of
   this Section 2, each Contributor hereby grants Recipient a
   non-exclusive, worldwide, royalty-free patent license under
   Licensed Patents to make, use, sell, offer to sell, import and
   otherwise transfer the Contribution of such Contributor, if any, in
   source code and object code form. This patent license shall apply
   to the combination of the Contribution and the Program if, at the
   time the Contribution is added by the Contributor, such addition of
   the Contribution causes such combination to be covered by the
   Licensed Patents. The patent license shall not apply to any other
   combinations which include the Contribution. No hardware per se is
   licensed hereunder.

   3. Recipient understands that although each Contributor grants the
   licenses to its Contributions set forth herein, no assurances are
   provided by any Contributor that the Program does not infringe the
   patent or other intellectual property rights of any other entity.
   Each Contributor disclaims any liability to Recipient for claims
   brought by any other entity based on infringement of intellectual
   property rights or otherwise. As a condition to exercising the
   rights and licenses granted hereunder, each Recipient hereby
   assumes sole responsibility to secure any other intellectual
   property rights needed, if any. For example, if a third party
   patent license is required to allow Recipient to distribute the
   Program, it is Recipient's responsibility to acquire that license
   before distributing the Program.

   4. Each Contributor represents that to its knowledge it has
   sufficient copyright rights in its Contribution, if any, to grant
   the copyright license set forth in this Agreement.

3. REQUIREMENTS

   A Contributor may choose to distribute the Program in object code
   form under its own license agreement, provided that:

      a. it complies with the terms and conditions of this Agreement; and

      b. its license agreement:

         i.  effectively disclaims on behalf of all Contributors all
         warranties and conditions, express and implied, including
         warranties or conditions of title and non-infringement, and
         implied warranties or conditions of merchantability and
         fitness for a particular purpose;

         ii.  effectively excludes on behalf of all Contributors all
         liability for damages, including direct, indirect, special,
         incidental and consequential damages, such as lost profits;

         iii. states that any provisions which differ from this
         Agreement are offered by that Contributor alone and not by
         any other party; and

         iv.  states that source code for the Program is available
         from such Contributor, and informs licensees how to obtain it
         in a reasonable manner on or through a medium customarily
         used for software exchange.

   When the Program is made available in source code form:

      a. it must be made available under this Agreement; and

      b. a copy of this Agreement must be included with each copy of
      the Program.

   Each Contributor must include the following in a conspicuous
   location in the Program:

   Copyright (c) {date here}, The Open Group Ltd. and others. All
   Rights Reserved.

   In addition, each Contributor must identify itself as the
   originator of its Contribution, if any, in a manner that reasonably
   allows subsequent Recipients to identify the originator of the
   Contribution.

4. COMMERCIAL DISTRIBUTION

   Commercial distributors of software may accept certain
   responsibilities with respect to end users, business partners and
   the like. While this license is intended to facilitate the
   commercial use of the Program, subject to the limitations provided
   in Section 2, the Contributor who includes the Program in a
   commercial product offering should do so in a manner which does not
   create potential liability for other Contributors. Therefore, if a
   Contributor includes the Program in a commercial product offering,
   such Contributor ("Commercial Contributor") hereby agrees to defend
   and indemnify every other Contributor ("Indemnified Contributor")
   against any losses, damages and costs (collectively "Losses")
   arising from claims, lawsuits and other legal actions brought by a
   third party against the Indemnified Contributor to the extent
   caused by the acts or omissions of such Commercial Contributor in
   connection with its distribution of the Program in a commercial
   product offering. The obligations in this section do not apply to
   any claims or Losses relating to any actual or alleged intellectual
   property infringement. In order to qualify, an Indemnified
   Contributor must:

   a. promptly notify the Commercial Contributor in writing of such
   claim, and

   b. allow the Commercial Contributor to control, and cooperate with
   the Commercial Contributor in, the defence and any related
   settlement negotiations.

   The Indemnified Contributor may participate in any such claim at
   its own expense.

   For example, a Contributor might include the Program in a
   commercial product offering, Product X. That Contributor is then a
   Commercial Contributor. If that Commercial Contributor then makes
   performance claims, or offers warranties related to Product X,
   those performance claims and warranties are such Commercial
   Contributor's responsibility alone. Under this section, the
   Commercial Contributor would have to defend claims against the
   other Contributors related to those performance claims and
   warranties, and if a court requires any other Contributor to pay
   any damages as a result, the Commercial Contributor must pay those
   damages.

5. NO WARRANTY

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
   PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF
   ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION,
   ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT,
   MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient
   is solely responsible for determining the appropriateness of using
   and distributing the Program and assumes all risks associated with
   its exercise of rights under this Agreement, including but not
   limited to the risks and costs of program errors, compliance with
   applicable laws, damage to or loss of data, programs or equipment,
   and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT
   NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT,
   INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES
   (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON
   ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR
   TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF
   THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY
   RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF
   SUCH DAMAGES.

7. GENERAL

   If any provision of this Agreement is invalid or unenforceable
   under applicable law, it shall not affect the validity or
   enforceability of the remainder of the terms of this Agreement, and
   without further action by the parties hereto, such provision shall
   be reformed to the minimum extent necessary to make such provision
   valid and enforceable.

   If Recipient institutes patent litigation or other similar official
   proceedings to enforce patent rights against a Contributor with
   respect to a patent applicable to software (including a cross-claim
   or counterclaim in a lawsuit), then any patent licenses granted by
   that Contributor to such Recipient under this Agreement shall
   terminate as of the date such litigation is filed. In addition, If
   Recipient institutes patent litigation against any entity
   (including a cross-claim or counterclaim in a lawsuit) alleging
   that the Program itself (excluding combinations of the Program with
   other software or hardware) infringes such Recipient's patent(s),
   then such Recipient's rights granted under Section 2(b) shall
   terminate as of the date such litigation is filed.

   All Recipient's rights under this Agreement shall terminate if it
   fails to comply with any of the material terms or conditions of
   this Agreement and does not cure such failure in a reasonable
   period of time after becoming aware of such non-compliance. If all
   Recipient's rights under this Agreement terminate, Recipient agrees
   to cease use and distribution of the Program as soon as reasonably
   practicable. However, Recipient's obligations under this Agreement
   and any licenses granted by Recipient relating to the Program shall
   continue and survive.

   The Open Group may publish new versions (including revisions) of
   this Agreement from time to time. Each new version of the Agreement
   will be given a distinguishing version number. The Program
   (including Contributions) may always be distributed subject to the
   version of the Agreement under which it was received. In addition,
   after a new version of the Agreement is published, Contributor may
   elect to distribute the Program (including its Contributions) under
   the new version. No one other than The Open Group has the right to
   modify this Agreement. Except as expressly stated in Sections 2(a)
   and 2(b) above, Recipient receives no rights or licenses to the
   intellectual property of any Contributor under this Agreement,
   whether expressly, by implication, estoppel or otherwise. All
   rights in the Program not expressly granted under this Agreement
   are reserved.

   No party to this Agreement will bring a legal action under this
   Agreement more than one year after the cause of action arose. Each
   party waives its rights to a jury trial in any resulting
   litigation.
