22
23THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS PUBLIC
24LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
25PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
26
271. DEFINITIONS
28
29"Contribution" means:
30
31 a. in the case of Lucent Technologies Inc. ("LUCENT"), the Original
32 Program, and
33 b. in the case of each Contributor,
34
35 i. changes to the Program, and
36 ii. additions to the Program;
37
38 where such changes and/or additions to the Program were added to the
39 Program by such Contributor itself or anyone acting on such
40 Contributor's behalf, and the Contributor explicitly consents, in
41 accordance with Section 3C, to characterization of the changes and/or
42 additions as Contributions.
43
44"Contributor" means LUCENT and any other entity that has Contributed a
45Contribution to the Program.
46
47"Distributor" means a Recipient that distributes the Program,
48modifications to the Program, or any part thereof.
49
50"Licensed Patents" mean patent claims licensable by a Contributor
51which are necessarily infringed by the use or sale of its Contribution
52alone or when combined with the Program.
53
54"Original Program" means the original version of the software
55accompanying this Agreement as released by LUCENT, including source
56code, object code and documentation, if any.
57
58"Program" means the Original Program and Contributions or any part
59thereof
60
61"Recipient" means anyone who receives the Program under this
62Agreement, including all Contributors.
63
642. GRANT OF RIGHTS
65
66 a. Subject to the terms of this Agreement, each Contributor hereby
67 grants Recipient a non-exclusive, worldwide, royalty-free copyright
68 license to reproduce, prepare derivative works of, publicly display,
69 publicly perform, distribute and sublicense the Contribution of such
70 Contributor, if any, and such derivative works, in source code and
71 object code form.
72
73 b. Subject to the terms of this Agreement, each Contributor hereby
74 grants Recipient a non-exclusive, worldwide, royalty-free patent
75 license under Licensed Patents to make, use, sell, offer to sell,
76 import and otherwise transfer the Contribution of such Contributor, if
77 any, in source code and object code form. The patent license granted
78 by a Contributor shall also apply to the combination of the
79 Contribution of that Contributor and the Program if, at the time the
80 Contribution is added by the Contributor, such addition of the
81 Contribution causes such combination to be covered by the Licensed
82 Patents. The patent license granted by a Contributor shall not apply
83 to (i) any other combinations which include the Contribution, nor to
84 (ii) Contributions of other Contributors. No hardware per se is
85 licensed hereunder.
86
87 c. Recipient understands that although each Contributor grants the
88 licenses to its Contributions set forth herein, no assurances are
89 provided by any Contributor that the Program does not infringe the
90 patent or other intellectual property rights of any other entity. Each
91 Contributor disclaims any liability to Recipient for claims brought by
92 any other entity based on infringement of intellectual property rights
93 or otherwise. As a condition to exercising the rights and licenses
94 granted hereunder, each Recipient hereby assumes sole responsibility
95 to secure any other intellectual property rights needed, if any. For
96 example, if a third party patent license is required to allow
97 Recipient to distribute the Program, it is Recipient's responsibility
98 to acquire that license before distributing the Program.
99
100 d. Each Contributor represents that to its knowledge it has sufficient
101 copyright rights in its Contribution, if any, to grant the copyright
102 license set forth in this Agreement.
103
1043. REQUIREMENTS
105
106A. Distributor may choose to distribute the Program in any form under
107this Agreement or under its own license agreement, provided that:
108
109 a. it complies with the terms and conditions of this Agreement;
110
111 b. if the Program is distributed in source code or other tangible
112 form, a copy of this Agreement or Distributor's own license agreement
113 is included with each copy of the Program; and
114
115 c. if distributed under Distributor's own license agreement, such
116 license agreement:
117
118 i. effectively disclaims on behalf of all Contributors all warranties
119 and conditions, express and implied, including warranties or
120 conditions of title and non-infringement, and implied warranties or
121 conditions of merchantability and fitness for a particular purpose;
122 ii. effectively excludes on behalf of all Contributors all liability
123 for damages, including direct, indirect, special, incidental and
124 consequential damages, such as lost profits; and
125 iii. states that any provisions which differ from this Agreement are
126 offered by that Contributor alone and not by any other party.
127
128B. Each Distributor must include the following in a conspicuous
129 location in the Program:
130
131 Copyright (C) 2003, Lucent Technologies Inc. and others. All Rights
132 Reserved.
133
134C. In addition, each Contributor must identify itself as the
135originator of its Contribution in a manner that reasonably allows
136subsequent Recipients to identify the originator of the Contribution.
137Also, each Contributor must agree that the additions and/or changes
138are intended to be a Contribution. Once a Contribution is contributed,
139it may not thereafter be revoked.
140
1414. COMMERCIAL DISTRIBUTION
142
143Commercial distributors of software may accept certain
144responsibilities with respect to end users, business partners and the
145like. While this license is intended to facilitate the commercial use
146of the Program, the Distributor who includes the Program in a
147commercial product offering should do so in a manner which does not
148create potential liability for Contributors. Therefore, if a
149Distributor includes the Program in a commercial product offering,
150such Distributor ("Commercial Distributor") hereby agrees to defend
151and indemnify every Contributor ("Indemnified Contributor") against
152any losses, damages and costs (collectively"Losses") arising from
153claims, lawsuits and other legal actions brought by a third party
154against the Indemnified Contributor to the extent caused by the acts
155or omissions of such Commercial Distributor in connection with its
156distribution of the Program in a commercial product offering. The
157obligations in this section do not apply to any claims or Losses
158relating to any actual or alleged intellectual property infringement.
159In order to qualify, an Indemnified Contributor must: a) promptly
160notify the Commercial Distributor in writing of such claim, and b)
161allow the Commercial Distributor to control, and cooperate with the
162Commercial Distributor in, the defense and any related settlement
163negotiations. The Indemnified Contributor may participate in any such
164claim at its own expense.
165
166For example, a Distributor might include the Program in a commercial
167product offering, Product X. That Distributor is then a Commercial
168Distributor. If that Commercial Distributor then makes performance
169claims, or offers warranties related to Product X, those performance
170claims and warranties are such Commercial Distributor's responsibility
171alone. Under this section, the Commercial Distributor would have to
172defend claims against the Contributors related to those performance
173claims and warranties, and if a court requires any Contributor to pay
174any damages as a result, the Commercial Distributor must pay those
175damages.
176
1775. NO WARRANTY
178
179EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS
180PROVIDED ON AN"AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
181KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY
182WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY
183OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely
184responsible for determining the appropriateness of using and
185distributing the Program and assumes all risks associated with its
186exercise of rights under this Agreement, including but not limited to
187the risks and costs of program errors, compliance with applicable
188laws, damage to or loss of data, programs or equipment, and
189unavailability or interruption of operations.
190
1916. DISCLAIMER OF LIABILITY
192
193EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
194ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
195INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
196WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
197LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
198NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
199DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
200HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
201
2027. EXPORT CONTROL
203
204Recipient agrees that Recipient alone is responsible for compliance
205with the United States export administration regulations (and the
206export control laws and regulation of any other countries).
207
2088. GENERAL
209
210If any provision of this Agreement is invalid or unenforceable under
211applicable law, it shall not affect the validity or enforceability of
212the remainder of the terms of this Agreement, and without further
213action by the parties hereto, such provision shall be reformed to the
214minimum extent necessary to make such provision valid and enforceable.
215
216If Recipient institutes patent litigation against a Contributor with
217respect to a patent applicable to software (including a cross-claim or
218counterclaim in a lawsuit), then any patent licenses granted by that
219Contributor to such Recipient under this Agreement shall terminate as
220of the date such litigation is filed. In addition, if Recipient
221institutes patent litigation against any entity (including a
222cross-claim or counterclaim in a lawsuit) alleging that the Program
223itself (excluding combinations of the Program with other software or
224hardware) infringes such Recipient's patent(s), then such Recipient's
225rights granted under Section 2(b) shall terminate as of the date such
226litigation is filed.
227
228All Recipient's rights under this Agreement shall terminate if it
229fails to comply with any of the material terms or conditions of this
230Agreement and does not cure such failure in a reasonable period of
231time after becoming aware of such noncompliance. If all Recipient's
232rights under this Agreement terminate, Recipient agrees to cease use
233and distribution of the Program as soon as reasonably practicable.
234However, Recipient's obligations under this Agreement and any licenses
235granted by Recipient relating to the Program shall continue and
236survive.
237
238LUCENT may publish new versions (including revisions) of this
239Agreement from time to time. Each new version of the Agreement will be
240given a distinguishing version number. The Program (including
241Contributions) may always be distributed subject to the version of the
242Agreement under which it was received. In addition, after a new
243version of the Agreement is published, Contributor may elect to
244distribute the Program (including its Contributions) under the new
245version. No one other than LUCENT has the right to modify this
246Agreement. Except as expressly stated in Sections 2(a) and 2(b) above,
247Recipient receives no rights or licenses to the intellectual property
248of any Contributor under this Agreement, whether expressly, by
249implication, estoppel or otherwise. All rights in the Program not
250expressly granted under this Agreement are reserved.
251
252This Agreement is governed by the laws of the State of New York and
253the intellectual property laws of the United States of America. No
254party to this Agreement will bring a legal action under this Agreement
255more than one year after the cause of action arose. Each party waives
256its rights to a jury trial in any resulting litigation.
