71.  DEFINITIONS
8
9"Contribution" means:  
10    a) in the case of International Business Machines Corporation ("IBM"), 
11       the Original Program, and 
12    b) in the case of each Contributor, 
13       i)  changes to the Program, and
14       ii) additions to the Program;
15           where such changes and/or additions to the Program originate
16           from and are distributed by that particular Contributor.  
17           A Contribution 'originates' from a Contributor if it was added 
18           to the Program by such Contributor itself or anyone acting on 
19           such Contributor's behalf.  
20    Contributions do not include additions to the Program which:
21       (i)  are separate modules of software distributed in conjunction 
22            with the Program under their own license agreement, and 
23       (ii) are not derivative works of the Program.
24
25"Contributor" means IBM and any other entity that distributes the Program.
26
27"Licensed Patents " mean patent claims licensable by a Contributor which
28are necessarily infringed by the use or sale of its Contribution alone
29or when combined with the Program.
30
31"Original Program" means the original version of the software accompanying
32this Agreement as released by IBM, including source code, object code
33and documentation, if any.
34
35"Program" means the Original Program and Contributions.
36
37"Recipient" means anyone who receives the Program under this Agreement, 
38including all Contributors.
39
402.  GRANT OF RIGHTS
41
42    a) Subject to the terms of this Agreement, each Contributor hereby
43    grants Recipient a non-exclusive, worldwide, royalty-free copyright
44    license to reproduce, prepare derivative works of, publicly display,
45    publicly perform, distribute and sublicense the Contribution of such
46    Contributor, if any, and such derivative works, in source code and
47    object code form.
48
49    b) Subject to the terms of this Agreement, each Contributor hereby
50    grants Recipient a non-exclusive, worldwide, royalty-free patent
51    license under Licensed Patents to make, use, sell, offer to sell,
52    import and otherwise transfer the Contribution of such Contributor,
53    if any, in source code and object code form.  This patent license
54    shall apply to the combination of the Contribution and the Program
55    if, at the time the Contribution is added by the Contributor, such
56    addition of the Contribution causes such combination to be covered
57    by the Licensed Patents.  The patent license shall not apply to any
58    other combinations which include the Contribution.  No hardware per
59    se is licensed hereunder.
60
61    c) Recipient understands that although each Contributor grants the
62    licenses to its Contributions set forth herein, no assurances are
63    provided by any Contributor that the Program does not infringe the
64    patent or other intellectual property rights of any other entity.
65    Each Contributor disclaims any liability to Recipient for claims
66    brought by any other entity based on infringement of intellectual
67    property rights or otherwise.  As a condition to exercising the rights
68    and licenses granted hereunder, each Recipient hereby assumes sole
69    responsibility to secure any other intellectual property rights
70    needed, if any.  For example, if a third party patent license
71    is required to allow Recipient to distribute the Program, it is
72    Recipient's responsibility to acquire that license before distributing
73    the Program.
74
75    d) Each Contributor represents that to its knowledge it has sufficient
76    copyright rights in its Contribution, if any, to grant the copyright
77    license set forth in this Agreement.
78
793.  REQUIREMENTS
80
81A Contributor may choose to distribute the Program in object code form 
82under its own license agreement, provided that:
83    a) it complies with the terms and conditions of this Agreement; and
84    b) its license agreement:
85       i)   effectively disclaims on behalf of all Contributors all
86            warranties and conditions, express and implied, including
87            warranties or conditions of title and non-infringement, and
88            implied warranties or conditions of merchantability and fitness
89            for a particular purpose;
90       ii)  effectively excludes on behalf of all Contributors all 
91            liability for damages, including direct, indirect, special, 
92            incidental and consequential damages, such as lost profits; 
93       iii) states that any provisions which differ from this Agreement 
94            are offered by that Contributor alone and not by any other 
95            party; and
96       iv)  states that source code for the Program is available from 
97            such Contributor, and informs licensees how to obtain it in a 
98            reasonable manner on or through a medium customarily used for 
99            software exchange. 
100
101When the Program is made available in source code form:
102    a) it must be made available under this Agreement; and 
103    b) a copy of this Agreement must be included with each copy of the 
104       Program.  
105
106Each Contributor must include the following in a conspicuous location 
107in the Program: 
108
109    Copyright (c) 1997,1998,1999, International Business Machines
110    Corporation and others. All Rights Reserved.
111
112In addition, each Contributor must identify itself as the originator of
113its Contribution, if any, in a manner that reasonably allows subsequent
114Recipients to identify the originator of the Contribution. 
115
1164.  COMMERCIAL DISTRIBUTION
117
118Commercial distributors of software may accept certain responsibilities
119with respect to end users, business partners and the like.  While this
120license is intended to facilitate the commercial use of the Program, the
121Contributor who includes the Program in a commercial product offering
122should do so in a manner which does not create potential liability for
123other Contributors.   Therefore, if a Contributor includes the Program in
124a commercial product offering, such Contributor ("Commercial Contributor")
125hereby agrees to defend and indemnify every other Contributor
126("Indemnified Contributor") against any losses, damages and costs
127(collectively "Losses") arising from claims, lawsuits and other legal
128actions brought by a third party against the Indemnified Contributor to
129the extent caused by the acts or omissions of such Commercial Contributor
130in connection with its distribution of the Program in a commercial
131product offering.  The obligations in this section do not apply to any
132claims or Losses relating to any actual or alleged intellectual property
133infringement.  In order to qualify, an Indemnified Contributor must:
134    a) promptly notify the Commercial Contributor in writing of such claim,
135and 
136    b) allow the Commercial Contributor to control, and cooperate with
137       the Commercial Contributor in, the defense and any related 
138       settlement negotiations.  The Indemnified Contributor may 
139       participate in any such claim at its own expense.
140
141For example, a Contributor might include the Program in a commercial
142product offering, Product X.  That Contributor is then a Commercial
143Contributor.  If that Commercial Contributor then makes performance
144claims, or offers warranties related to Product X, those performance
145claims and warranties are such Commercial Contributor's responsibility
146alone.  Under this section, the Commercial Contributor would have to
147defend claims against the other Contributors related to those performance
148claims and warranties, and if a court requires any other Contributor to
149pay any damages as a result, the Commercial Contributor must pay those
150damages.
151
1525.  NO WARRANTY
153
154EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED
155ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER
156EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
157CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A
158PARTICULAR PURPOSE. Each Recipient is solely responsible for determining
159the appropriateness of using and distributing the Program and assumes
160all risks associated with its exercise of rights under this Agreement,
161including but not limited to the risks and costs of program errors,
162compliance with applicable laws, damage to or loss of data, programs or
163equipment, and unavailability or interruption of operations. 
164
1656.  DISCLAIMER OF LIABILITY
166
167EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
168ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
169INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
170WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
171LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
172NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION
173OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF
174ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
175
1767.  GENERAL
177
178If any provision of this Agreement is invalid or unenforceable under
179applicable law, it shall not affect the validity or enforceability of
180the remainder of the terms of this Agreement, and without further action
181by the parties hereto, such provision shall be reformed to the minimum
182extent necessary to make such provision valid and enforceable.
183
184If Recipient institutes patent litigation against a Contributor with
185respect to a patent applicable to software (including a cross-claim or
186counterclaim in a lawsuit), then any patent licenses granted by that
187Contributor to such Recipient under this Agreement shall terminate
188as of the date such litigation is filed.  In addition, If Recipient
189institutes patent litigation against any entity (including a cross-claim
190or counterclaim in a lawsuit) alleging that the Program itself (excluding
191combinations of the Program with other software or hardware) infringes
192such Recipient's patent(s), then such Recipient's rights granted under
193Section 2(b) shall terminate as of the date such litigation is filed.
194
195All Recipient's rights under this Agreement shall terminate if it fails
196to comply with any of the material terms or conditions of this Agreement
197and does not cure such failure in a reasonable period of time after
198becoming aware of such noncompliance.  If all Recipient's rights under
199this Agreement terminate, Recipient agrees to cease use and distribution
200of the Program as soon as reasonably practicable.  However, Recipient's
201obligations under this Agreement and any licenses granted by Recipient
202relating to the Program shall continue and survive. 
203
204IBM may publish new versions (including revisions) of this Agreement
205from time to time.  Each new version of the Agreement will be given a
206distinguishing version number.  The Program (including Contributions)
207may always be distributed subject to the version of the Agreement under
208which it was received. In addition, after a new version of the Agreement
209is published, Contributor may elect to distribute the Program (including
210its Contributions) under the new version. No one other than IBM has the
211right to modify this Agreement.  Except as expressly stated in Sections
2122(a) and 2(b) above, Recipient receives no rights or licenses to the
213intellectual property of any Contributor under this Agreement, whether
214expressly, by implication, estoppel or otherwise.  All rights in the
215Program not expressly granted under this Agreement are reserved.
216
217This Agreement is governed by the laws of the State of New York and the
218intellectual property laws of the United States of America. No party to
219this Agreement will bring a legal action under this Agreement more than
220one year after the cause of action arose.  Each party waives its rights
221to a jury trial in any resulting litigation.
