+
+2.4 Subcontracting.
+
+You may deliver the Source Code of Covered Code to other Licensees 
+having at least a Research Use license, for the sole purpose of 
+furnishing development services to You in connection with Your rights 
+granted in this License. All such Licensees must execute appropriate 
+documents with respect to such work consistent with the terms of this 
+License, and acknowledging their work-made-for-hire status or assigning 
+exclusive right to the work product and associated Intellectual Property 
+Rights to You.
+
+*3. Requirements and Responsibilities.*
+
+3.1 Research Use License.
+
+As a condition of exercising the rights granted under Section 2.1(a) 
+above, You agree to comply with the following:
+
+(a) Your Contribution to the Community. All Error Corrections and Shared 
+Modifications which You create or contribute to are automatically 
+subject to the licenses granted under Section 2.2 above. You are 
+encouraged to license all of Your other Modifications under Section 2.2 
+as Shared Modifications, but are not required to do so. You agree to 
+notify Original Contributor of any errors in the Specification.
+
+(b) Source Code Availability. You agree to provide all Your Error 
+Corrections to Original Contributor as soon as reasonably practicable 
+and, in any event, prior to Internal Deployment Use or Commercial Use, 
+if applicable. Original Contributor may, at its discretion, post Source 
+Code for Your Error Corrections and Shared Modifications on the 
+Community Webserver. You may also post Error Corrections and Shared 
+Modifications on a web-server of Your choice; provided, that You must 
+take reasonable precautions to ensure that only Licensees have access to 
+such Error Corrections and Shared Modifications. Such precautions shall 
+include, without limitation, a password protection scheme limited to 
+Licensees and a click-on, download certification of Licensee status 
+required of those attempting to download from the server. An example of 
+an acceptable certification is attached as Attachment A-2.
+
+(c) Notices. All Error Corrections and Shared Modifications You create 
+or contribute to must include a file documenting the additions and 
+changes You made and the date of such additions and changes. You must 
+also include the notice set forth in Attachment A-1 in the file header. 
+If it is not possible to put the notice in a particular Source Code file 
+due to its structure, then You must include the notice in a location 
+(such as a relevant directory file), where a recipient would be most 
+likely to look for such a notice.
+
+(d) Redistribution.
+
+(i) Source. Covered Code may be distributed in Source Code form only to 
+another Licensee (except for students as provided below). You may not 
+offer or impose any terms on any Covered Code that alter the rights, 
+requirements, or responsibilities of such Licensee. You may distribute 
+Covered Code to students for use in connection with their course work 
+and research projects undertaken at accredited educational institutions. 
+Such students need not be Licensees, but must be given a copy of the 
+notice set forth in Attachment A-3 and such notice must also be included 
+in a file header or prominent location in the Source Code made available 
+to such students.
+
+(ii) Executable. You may distribute Executable version(s) of Covered 
+Code to Licensees and other third parties only for the purpose of 
+evaluation and comment in connection with Research Use by You and under 
+a license of Your choice, but which limits use of such Executable 
+version(s) of Covered Code only to that purpose.
+
+(iii) Modified Class, Interface and Package Naming. In connection with 
+Research Use by You only, You may use Original Contributor's class, 
+Interface and package names only to accurately reference or invoke the 
+Source Code files You modify. Original Contributor grants to You a 
+limited license to the extent necessary for such purposes.
+
+(iv) You expressly agree that any distribution, in whole or in part, of 
+Modifications developed by You shall only be done pursuant to the terms 
+and conditions of this License.
+
+(e) Extensions.
+
+(i) Covered Code. You may not include any Source Code of Community Code 
+in any Extensions. You may include the compiled Header Files of 
+Community Code in an Extension provided that your use of the Covered 
+Code, including Heading Files, complies with the Commercial Use License, 
+the TCK and all other terms of this License.
+
+(ii) Publication. No later than the date on which You first distribute 
+such Extension for Commercial Use, You must publish to the industry, on 
+a non-confidential basis and free of all copyright restrictions with 
+respect to reproduction and use, an accurate and current specification 
+for any Extension. In addition, You must make available an appropriate 
+test suite, pursuant to the same rights as the specification, 
+sufficiently detailed to allow any third party reasonably skilled in the 
+technology to produce implementations of the Extension compatible with 
+the specification. Such test suites must be made available as soon as 
+reasonably practicable but, in no event, later than ninety (90) days 
+after Your first Commercial Use of the Extension. You must use 
+reasonable efforts to promptly clarify and correct the specification and 
+the test suite upon written request by Original Contributor.
+
+(iii) Open. You agree to refrain from enforcing any Intellectual 
+Property Rights You may have covering any interface(s) of Your 
+Extension, which would prevent the implementation of such interface(s) 
+by Original Contributor or any Licensee. This obligation does not 
+prevent You from enforcing any Intellectual Property Right You have that 
+would otherwise be infringed by an implementation of Your Extension.
+
+(iv) Interface Modifications and Naming. You may not modify or add to 
+the GUID space "xxxxxxxx-0901-11d1-8B06-00A024406D59" or any other GUID 
+space designated by Original Contributor. You may not modify any 
+Interface prefix provided with the Covered Code or any other prefix 
+designated by Original Contributor.
+
+(f) You agree that any Specifications provided to You by Original 
+Contributor are confidential and proprietary information of Original 
+Contributor. You must maintain the confidentiality of the Specifications 
+and may not disclose them to any third party without Original 
+Contributor's prior written consent. You may only use the Specifications 
+under the terms of this License and only for the purpose of implementing 
+the terms of this License with respect to Covered Code. You agree not 
+use, copy or distribute any such Specifications except as provided in 
+writing by Original Contributor.

+The Covered Code 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

+Licensee Marks to Original Contributor upon request by Original 
+Contributor. Original Contributor acknowledges that the Licensee Marks 
+are the trademarks of Licensee. Original Contributor shall not use the 
+Licensee Marks in a way that may imply that Original Contributor is an 
+agency or branch of Licensee. Original Contributor understands and 
+agrees that the use of any Licensee Marks in connection with this 
+Agreement shall not create any right, title or interest, in, or to the 
+Licensee Marks or any Licensee trademarks and that all such use and 
+goodwill associated with any such trademarks will inure to the benefit 
+of Licensee. Further the Original Contributor will stop usage of the 
+Licensee Marks upon Licensee's request.
