Common Public License - v 1.0

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

1. DEFINITIONS

"Contribution" means:

      a) in the case of the initial Contributor, the initial code and
      documentation distributed under this Agreement, and b) in the case of
      each subsequent 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, and (ii) are not derivative works of
      the Program. 

"Contributor" means any person or 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.

"Program" means the Contributions distributed in accordance with this
Agreement.

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

2. GRANT OF RIGHTS

      a) Subject to the terms of this Agreement, 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.

      b) Subject to the terms of this Agreement, 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. 

      c) 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.

      d) 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. 

Contributors may not remove or alter any copyright notices contained within
the Program.

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, 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 defense 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 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 noncompliance. 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.

Everyone is permitted to copy and distribute copies of this Agreement, but in
order to avoid inconsistency the Agreement is copyrighted and may only be
modified in the following manner. The Agreement Steward reserves the right to
publish new versions (including revisions) of this Agreement from time to
time. No one other than the Agreement Steward has the right to modify this
Agreement. IBM is the initial Agreement Steward. IBM may assign the
responsibility to serve as the Agreement Steward to a suitable separate
entity. 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. 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.

This Agreement is governed by the laws of the State of New York and the
intellectual property laws of the United States of America. 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.
