CONTRIBUTING

Contribution License Agreement

In order to clarify the intellectual property license granted with
Contributions from any person or entity, BAE Systems Information and Electronic
Systems Integration Inc. ("BAE Systems") must have a Contribution License
Agreement ("Agreement") on file that has been signed by each Contributor,
indicating agreement to the license terms below. This license is for your
protection as a Contributor as well as the protection of BAE Systems; it does
not change your rights to use your own Contributions for any other purpose.

You accept and agree to the following terms and conditions for Your present and
future Contributions submitted to BAE Systems. Except for the license granted
herein to BAE Systems and recipients of software distributed by BAE Systems,
You reserve all right, title, and interest in and to Your Contributions.

1. Definitions.

"You" (or "Your") shall mean the copyright owner or legal entity authorized by
the copyright owner that is making this Agreement with BAE Systems. For legal
entities, the entity making a Contribution and all other entities that control,
are controlled by, or are under common control with that entity are considered
to be a single Contributor. For the purposes of this definition, "control"
means (i) the power, direct or indirect, to cause the direction or management
of such entity, whether by contract or otherwise, or (ii) ownership of fifty
percent (50%) or more of the outstanding shares, or (iii) beneficial ownership
of such entity.

"Contribution" shall mean any original work of authorship, including any
modifications or additions to an existing work, that is intentionally submitted
by You to BAE Systems for inclusion in, or documentation of, any of the
projects owned or managed by BAE Systems (the "Work"). For the purposes of this
definition, "submitted" means any form of electronic, verbal, or written
communication sent to BAE Systems or its representatives, including but not
limited to communication on electronic mailing lists, source code control
systems, and issue tracking systems that are managed by, or on behalf of, BAE
Systems for the purpose of discussing and improving the Work, but excluding
communication that is conspicuously marked or otherwise designated in writing
by You as "Not a Contribution."

2. Your Submission. You must agree to the terms of this Agreement before making
any Contributions to BAE Systems. This Agreement covers any and all
Contributions that You, now or in the future, submit to BAE Systems.

3. Originality of Work. You represent that each of Your Contributions is Your
original creation (see Section 4 for submissions on behalf of others). You
represent that Your Contribution submissions include complete details of any
third-party license or other restriction (including, but not limited to,
related patents and trademarks) of which you are personally aware and which are
associated with any part of Your Contributions.

4. Contribution on Behalf of Others. Should You wish to submit work that is not
Your original creation, You may submit it to BAE Systems separately from any
Contribution, identifying the complete details of its source and of any license
or other restriction (including, but not limited to, related patents,
trademarks, and license agreements) of which you are personally aware, and
conspicuously marking the work as "Submitted on behalf of a third-party: [named
here]".

5. Your Employer. You represent that you are legally entitled to grant the
licenses provided by this Agreement. If your employer(s) has rights to
intellectual property that you create that includes your Contributions, You
represent that you have received permission to make Contributions on behalf of
that employer, that your employer has waived such rights for your Contributions
to BAE Systems, or that your employer has executed a separate Contribution
License Agreement with BAE Systems. If You change employers in the future and
desire to submit additional submissions for the new employer, then You agree to
sign a new Agreement and secure permission from the new employer before
submitting those Contributions.

6. Grant of Copyright License.  Subject to the terms and conditions of this
Agreement, You hereby grant to BAE Systems and to recipients of software
distributed by BAE Systems a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable copyright license to reproduce, prepare derivative
works of, publicly display, publicly perform, sublicense, and distribute Your
Contributions and such derivative works.

7. Grant of Patent License.  Subject to the terms and conditions of this
Agreement, You hereby grant to BAE Systems and to recipients of software
distributed by BAE Systems a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable (except as stated in this section) patent license to
make, have made, use, offer to sell, sell, import, and otherwise transfer the
Work, where such license applies only to those patent claims licensable by You
that are necessarily infringed by Your Contribution(s) alone or by combination
of Your Contribution(s) with the Work to which such Contribution(s) was
submitted. If any entity institutes patent litigation against You or any other
entity (including a cross-claim or counterclaim in a lawsuit) alleging that
Your Contribution, or the Work to which You have contributed, constitutes
direct or contributory patent infringement, then any patent licenses granted to
that entity under this Agreement for that Contribution or Work shall terminate
as of the date such litigation is filed.

8. Support and Warranty. You are not expected to provide support for Your
Contributions, except to the extent You desire to provide support. You may
provide support for free, for a fee, or not at all. Unless required by
applicable law or agreed to in writing, You provide Your Contributions 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.

9. Notification. You agree to notify BAE Systems of any facts or circumstances
of which you become aware that would make these representations inaccurate in
any respect.
