Reciprocal Public License 1.5 (RPL1.5)

Version 1.5, July 15, 2007

Copyright (C) 2001-2007 Technical Pursuit Inc., All Rights Reserved.

PREAMBLE

The Reciprocal Public License (RPL) is based on the concept of reciprocity
or, if you prefer, fairness.

In short, this license grew out of a desire to close loopholes in previous
open source licenses, loopholes that allowed parties to acquire open source
software and derive financial benefit from it without having to release their
improvements or derivatives to the community which enabled them. This occurred
any time an entity did not release their application to a "third party".

While there is a certain freedom in this model of licensing, it struck the
authors of the RPL as being unfair to the open source community at large and
to the original authors of the works in particular. After all, bug fixes,
extensions, and meaningful and valuable derivatives were not consistently
finding their way back into the community where they could fuel further, and
faster, growth and expansion of the overall open source software base.

While you should clearly read and understand the entire license, the essence
of the RPL is found in two definitions: "Deploy" and "Required Components".

Regarding deployment, under the RPL your changes, bug fixes, extensions, etc.
must be made available to the open source community at large when you Deploy
in any form -- either internally or to an outside party. Once you start running
the software you have to start sharing the software.

Further, under the RPL all components you author including schemas, scripts,
source code, etc. -- regardless of whether they're compiled into a single
binary or used as two halves of client/server application -- must be shared.
You have to share the whole pie, not an isolated slice of it.

In addition to these goals, the RPL was authored to meet the requirements
of the Open Source Definition as maintained by the Open Source Initiative
(OSI).

The specific terms and conditions of the license are defined in the remainder
of this document.

to grant any rights to trademarks, copyrights, patents, trade secrets or any
other intellectual property of Licensor or any Contributor except as expressly
stated herein. Except as expressly stated in Sections 3 and 4, no other patent
rights, express or implied, are granted herein. Your Extensions may require
additional patent licenses from Licensor or Contributors which each may grant
in its sole discretion. No right is granted to the trademarks of Licensor
or any Contributor even if such marks are included in the Licensed Software.
Nothing in this License shall be interpreted to prohibit Licensor from licensing
under different terms from this License any code that Licensor otherwise would
have a right to license.

5.1 You expressly acknowledge and agree that although Licensor and each Contributor
grants the licenses to their respective portions of the Licensed Software
set forth herein, no assurances are provided by Licensor or any Contributor
that the Licensed Software does not infringe the patent or other intellectual
property rights of any other entity. Licensor and each Contributor disclaim
any liability to You 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, You hereby assume sole responsibility
to secure any other intellectual property rights needed, if any. For example,
if a third party patent license is required to allow You to distribute the
Licensed Software, it is Your responsibility to acquire that license before
distributing the Licensed Software.

6.0 Your Obligations And Grants. In consideration of, and as an express condition
to, the licenses granted to You under this License You hereby agree that any
Modifications, Derivative Works, or Required Components (collectively Extensions)
that You create or to which You contribute are governed by the terms of this
License including, without limitation, Section 4. Any Extensions that You
create or to which You contribute must be Deployed under the terms of this
License or a future version of this License released under Section 7. You
hereby grant to Licensor and all third parties a world-wide, non-exclusive,
royalty-free license under those intellectual property rights You own or control
to use, reproduce, display, perform, modify, create derivatives, sublicense,
and distribute Licensed Software, in any form. Any Extensions You make and
Deploy must have a distinct title so as to readily tell any subsequent user
or Contributor that the Extensions are by You. You must include a copy of
this License or directions on how to obtain a copy with every copy of the
Extensions You distribute. You agree not to offer or impose any terms on any
Source Code or executable version of the Licensed Software, or its Extensions
that alter or restrict the applicable version of this License or the recipients'
rights hereunder.

6.1 Availability of Source Code. You must make available, under the terms
of this License, the Source Code of any Extensions that You Deploy, via an
Electronic Distribution Mechanism. The Source Code for any version that You
Deploy must be made available within one (1) month of when you Deploy and
must remain available for no less than twelve (12) months after the date You
cease to Deploy. You are responsible for ensuring that the Source Code to
each version You Deploy remains available even if the Electronic Distribution
Mechanism is maintained by a third party. You may not charge a fee for any
copy of the Source Code distributed under this Section in excess of Your actual
cost of duplication and distribution of said copy.

6.2 Description of Modifications. You must cause any Modifications that You
create or to which You contribute to be documented in the Source Code, clearly
describing the additions, changes or deletions You made. You must include
a prominent statement that the Modifications are derived, directly or indirectly,
from the Licensed Software and include the names of the Licensor and any Contributor
to the Licensed Software in (i) the Source Code and (ii) in any notice displayed
by the Licensed Software You distribute or in related documentation in which
You describe the origin or ownership of the Licensed Software. You may not
modify or delete any pre-existing copyright notices, change notices or License
text in the Licensed Software without written permission of the respective
Licensor or Contributor.

     6.3 Intellectual Property Matters.

a. Third Party Claims. If You have knowledge that a license to a third party's
intellectual property right is required to exercise the rights granted by
this License, You must include a human-readable file with Your distribution
that describes the claim and the party making the claim in sufficient detail
that a recipient will know whom to contact.

b. Contributor APIs. If Your Extensions include an application programming
interface ("API") and You have knowledge of patent licenses that are reasonably
necessary to implement that API, You must also include this information in
a human-readable file supplied with Your distribution.

c. Representations. You represent that, except as disclosed pursuant to 6.3(a)
above, You believe that any Extensions You distribute are Your original creations
and that You have sufficient rights to grant the rights conveyed by this License.

     6.4 Required Notices.

a. License Text. You must duplicate this License or instructions on how to
acquire a copy in any documentation You provide along with the Source Code
of any Extensions You create or to which You contribute, wherever You describe
recipients' rights relating to Licensed Software.

b. License Notice. You must duplicate any notice contained in EXHIBIT A (the
"License Notice") in each file of the Source Code of any copy You distribute
of the Licensed Software and Your Extensions. If You create an Extension,
You may add Your name as a Contributor to the Source Code and accompanying
documentation along with a description of the contribution. If it is not possible
to put the License Notice in a particular Source Code file due to its structure,
then You must include such License Notice in a location where a user would
be likely to look for such a notice.

c. Source Code Availability. You must notify the software community of the
availability of Source Code to Your Extensions within one (1) month of the
date You initially Deploy and include in such notification a description of
the Extensions, and instructions on how to acquire the Source Code. Should
such instructions change you must notify the software community of revised
instructions within one (1) month of the date of change. You must provide
notification by posting to appropriate news groups, mailing lists, weblogs,
or other sites where a publicly accessible search engine would reasonably
be expected to index your post in relationship to queries regarding the Licensed
Software and/or Your Extensions.

d. User-Visible Attribution. You must duplicate any notice contained in EXHIBIT
B (the "User-Visible Attribution Notice") in each user-visible display of
the Licensed Software and Your Extensions which delineates copyright, ownership,
or similar attribution information. If You create an Extension, You may add
Your name as a Contributor, and add Your attribution notice, as an equally
visible and functional element of any User-Visible Attribution Notice content.
To ensure proper attribution, You must also include such User-Visible Attribution
Notice in at least one location in the Software documentation where a user
would be likely to look for such notice.

6.5 Additional Terms. You may choose to offer, and charge a fee for, warranty,
support, indemnity or liability obligations to one or more recipients of Licensed
Software. However, You may do so only on Your own behalf, and not on behalf
of the Licensor or any Contributor except as permitted under other agreements
between you and Licensor or Contributor. You must make it clear that any such
warranty, support, indemnity or liability obligation is offered by You alone,
and You hereby agree to indemnify the Licensor and every Contributor for any
liability plus attorney fees, costs, and related expenses due to any such
action or claim incurred by the Licensor or such Contributor as a result of
warranty, support, indemnity or liability terms You offer.

6.6 Conflicts With Other Licenses. Where any portion of Your Extensions, by
virtue of being Derivative Works of another product or similar circumstance,
fall under the terms of another license, the terms of that license should
be honored however You must also make Your Extensions available under this
License. If the terms of this License continue to conflict with the terms
of the other license you may write the Licensor for permission to resolve
the conflict in a fashion that remains consistent with the intent of this
License. Such permission will be granted at the sole discretion of the Licensor.

7.0 Versions of This License. Licensor may publish from time to time revised
versions of the License. Once Licensed Software has been published under a
particular version of the License, You may always continue to use it under
the terms of that version. You may also choose to use such Licensed Software
under the terms of any subsequent version of the License published by Licensor.
No one other than Licensor has the right to modify the terms applicable to
Licensed Software created under this License.

7.1 If You create or use a modified version of this License, which You may
do only in order to apply it to software that is not already Licensed Software
under this License, You must rename Your license so that it is not confusingly
similar to this License, and must make it clear that Your license contains
terms that differ from this License. In so naming Your license, You may not
use any trademark of Licensor or of any Contributor. Should Your modifications
to this License be limited to alteration of a) Section 13.8 solely to modify
the legal Jurisdiction or Venue for disputes, b) EXHIBIT A solely to define
License Notice text, or c) to EXHIBIT B solely to define a User-Visible Attribution
Notice, You may continue to refer to Your License as the Reciprocal Public
License or simply the RPL.

8.0 Disclaimer of Warranty. LICENSED SOFTWARE IS PROVIDED UNDER THIS LICENSE
ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED,
INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED SOFTWARE IS FREE
OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
FURTHER THERE IS NO WARRANTY MADE AND ALL IMPLIED WARRANTIES ARE DISCLAIMED

LICENSOR DISCLAIMS ANY WARRANTY, IMPLIED OR EXPRESSED, THAT ANY CONTRIBUTOR'S
EXTENSIONS MEET ANY STANDARD OF COMPATIBILITY OR DESCRIPTION OF PERFORMANCE.
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LICENSED SOFTWARE
IS WITH YOU. SHOULD LICENSED SOFTWARE PROVE DEFECTIVE IN ANY RESPECT, YOU
(AND NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY
SERVICING, REPAIR OR CORRECTION. UNDER THE TERMS OF THIS LICENSOR WILL NOT
SUPPORT THIS SOFTWARE AND IS UNDER NO OBLIGATION TO ISSUE UPDATES TO THIS
SOFTWARE. LICENSOR HAS NO KNOWLEDGE OF ERRANT CODE OR VIRUS IN THIS SOFTWARE,
BUT DOES NOT WARRANT THAT THE SOFTWARE IS FREE FROM SUCH ERRORS OR VIRUSES.
THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE.
NO USE OF LICENSED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.

9.0 Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY,
WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE LICENSOR,

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.

10.0 High Risk Activities. THE LICENSED SOFTWARE IS NOT FAULT-TOLERANT AND
IS NOT DESIGNED, MANUFACTURED, OR INTENDED FOR USE OR DISTRIBUTION AS ON-LINE
CONTROL EQUIPMENT IN HAZARDOUS ENVIRONMENTS REQUIRING FAIL-SAFE PERFORMANCE,
SUCH AS IN THE OPERATION OF NUCLEAR FACILITIES, AIRCRAFT NAVIGATION OR COMMUNICATIONS
SYSTEMS, AIR TRAFFIC CONTROL, DIRECT LIFE SUPPORT MACHINES, OR WEAPONS SYSTEMS,
IN WHICH THE FAILURE OF THE LICENSED SOFTWARE COULD LEAD DIRECTLY TO DEATH,
PERSONAL INJURY, OR SEVERE PHYSICAL OR ENVIRONMENTAL DAMAGE ("HIGH RISK ACTIVITIES").
LICENSOR AND CONTRIBUTORS SPECIFICALLY DISCLAIM ANY EXPRESS OR IMPLIED WARRANTY
OF FITNESS FOR HIGH RISK ACTIVITIES.

11.0 Responsibility for Claims. As between Licensor and Contributors, each
party is responsible for claims and damages arising, directly or indirectly,
out of its utilization of rights under this License which specifically disclaims
warranties and limits any liability of the Licensor. This paragraph is to
be used in conjunction with and controlled by the Disclaimer Of Warranties
of Section 8, the Limitation Of Damages in Section 9, and the disclaimer against
use for High Risk Activities in Section 10. The Licensor has thereby disclaimed
all warranties and limited any damages that it is or may be liable for. You
agree to work with Licensor and Contributors to distribute such responsibility
on an equitable basis consistent with the terms of this License including
Sections 8, 9, and 10. Nothing herein is intended or shall be deemed to constitute
any admission of liability.

12.0 Termination. This License and all rights granted hereunder will terminate
immediately in the event of the circumstances described in Section 13.6 or
if applicable law prohibits or restricts You from fully and or specifically
complying with Sections 3, 4 and/or 6, or prevents the enforceability of any
of those Sections, and You must immediately discontinue any use of Licensed
Software.

12.1 Automatic Termination Upon Breach. This License and the rights granted
hereunder will terminate automatically if You fail to comply with the terms
herein and fail to cure such breach within thirty (30) days of becoming aware
of the breach. All sublicenses to the Licensed Software that are properly
granted shall survive any termination of this License. Provisions that, by
their nature, must remain in effect beyond the termination of this License,
shall survive.

12.2 Termination Upon Assertion of Patent Infringement. If You initiate litigation
by asserting a patent infringement claim (excluding declaratory judgment actions)
against Licensor or a Contributor (Licensor or Contributor against whom You
file such an action is referred to herein as "Respondent") alleging that Licensed
Software directly or indirectly infringes any patent, then any and all rights
granted by such Respondent to You under Sections 3 or 4 of this License shall
terminate prospectively upon sixty (60) days notice from Respondent (the "Notice
Period") unless within that Notice Period You either agree in writing (i)
to pay Respondent a mutually agreeable reasonably royalty for Your past or
future use of Licensed Software made by such Respondent, or (ii) withdraw
Your litigation claim with respect to Licensed Software against such Respondent.
If within said Notice Period 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 Licensor to You under Sections 3 and
4 automatically terminate at the expiration of said Notice Period.

12.3 Reasonable Value of This License. If You assert a patent infringement
claim against Respondent alleging that Licensed Software 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 said Respondent under Sections 3 and 4 shall
be taken into account in determining the amount or value of any payment or
license.

12.4 No Retroactive Effect of Termination. In the event of termination under
this Section all end user license agreements (excluding licenses to distributors
and resellers) that have been validly granted by You or any distributor hereunder
prior to termination shall survive termination.

13.0 Miscellaneous.

13.1 U.S. Government End Users. The Licensed Software is a "commercial item,"
as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial
computer software" and "commercial computer software documentation," as such
terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R.
12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government
End Users acquire Licensed Software with only those rights set forth herein.

13.2 Relationship of Parties. This License will not be construed as creating
an agency, partnership, joint venture, or any other form of legal association
between or among You, Licensor, or any Contributor, and You will not represent
to the contrary, whether expressly, by implication, appearance, or otherwise.

13.3 Independent Development. Nothing in this License will impair Licensor's
right to acquire, license, develop, subcontract, market, or distribute technology
or products that perform the same or similar functions as, or otherwise compete
with, Extensions that You may develop, produce, market, or distribute.

13.4 Consent To Breach Not Waiver. Failure by Licensor or Contributor to enforce
any provision of this License will not be deemed a waiver of future enforcement
of that or any other provision.

13.5 Severability. This License represents the complete agreement concerning
the subject matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent necessary
to make it enforceable.

13.6 Inability to Comply Due to Statute or Regulation. If it is impossible
for You to comply with any of the terms of this License with respect to some
or all of the Licensed Software due to statute, judicial order, or regulation,
then You cannot use, modify, or distribute the software.

13.7 Export Restrictions. You may be restricted with respect to downloading
or otherwise acquiring, exporting, or reexporting the Licensed Software or
any underlying information or technology by United States and other applicable
laws and regulations. By downloading or by otherwise obtaining the Licensed
Software, You are agreeing to be responsible for compliance with all applicable
laws and regulations.

13.8 Arbitration, Jurisdiction & Venue. This License shall be governed by
Colorado law provisions (except to the extent applicable law, if any, provides
otherwise), excluding its conflict-of-law provisions. You expressly agree
that any dispute relating to this License shall be submitted to binding arbitration
under the rules then prevailing of the American Arbitration Association. You
further agree that Adams County, Colorado USA is proper venue and grant such
arbitration proceeding jurisdiction as may be appropriate for purposes of
resolving any dispute under this License. Judgement upon any award made in
arbitration may be entered and enforced in any court of competent jurisdiction.
The arbitrator shall award attorney's fees and costs of arbitration to the
prevailing party. Should either party find it necessary to enforce its arbitration
award or seek specific performance of such award in a civil court of competent
jurisdiction, the prevailing party shall be entitled to reasonable attorney's
fees and costs. The application of the United Nations Convention on Contracts
for the International Sale of Goods is expressly excluded. You and Licensor
expressly waive any rights to a jury trial in any litigation concerning Licensed
Software or this License. Any law or regulation that provides that the language
of a contract shall be construed against the drafter shall not apply to this
License.

13.9 Entire Agreement. This License constitutes the entire agreement between
the parties with respect to the subject matter hereof.
