       2.4 TERMINATION
        
This License shall terminate automatically and You may no longer exercise

a patent; or (b) automatically without notice from Cadence if you fail
to comply with the terms of this License and fail to cure such breach

3. REQUIRED NOTICES IN SOURCE CODE

You agree to retain, without alteration, all copyright notices contained
in all copies or substantial portions of the files comprising the
Licensed Work.  You must cause any modified files to carry prominent
notices indicating the changes you have made to the files.  If it is not
possible to put such notice in a particular Source Code file due to its
structure, then You must include such notice in a location (such as a
relevant directory in which the file is stored) where a Recipient would
be likely to look for such a notice.

Larger Work, You must deliver your Contribution in Source Code format

distribute your Contribution under this License yourself or through other
Distributors, provided that you are prohibited from using the names of
Cadence or any other Contributor, or any of their trademarks or service
marks, to endorse or promote your Contribution, without express written
permission from Cadence or the other Contributor.

5. NO WARRANTY

THE LICENSED WORK IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS
"AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING
BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE AND NONINFRINGEMENT. USE OF THE LICENSED WORK IS AT
YOUR SOLE RISK AND EXPENSE.  IN NO EVENT SHALL THE AUTHORS, CONTRIBUTORS
OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
OF ANY TYPE, WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING
FROM, OUT OF OR IN CONNECTION WITH THE LICENSED WORK OR THE USE OR OTHER
DEALINGS IN THE LICENSED WORK.

6. ACKNOWLEDGEMENT AND DISCLAIMER

You expressly acknowledge and agree that although Cadence and each
Contributor grants the licenses to their respective portions of the
Licensed Work, no assurances are provided by Cadence or any Contributor
that the Licensed Work does not infringe the patent or any intellectual
property rights of any other entity. Cadence and each Contributor disclaim
any liability to users or other Contributors for claims brought by any
other individual or 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
Contribution or the Licensed Work, it is your responsibility to acquire
that license before distributing the Contribution or the Licensed Work.


7. INDEMNITY FROM COMMERCIAL USERS. 

If a Distributor distributes either the Licensed Work or any portion
thereof, or a Larger Work in a commercial product offering or offers
any services in connection therewith, such Distributor ("Commercial
Distributor") hereby agrees to defend and indemnify Cadence and every
other Contributor (in each case an "Indemnified Party") against any
losses, damages and costs (collectively "Losses") arising from claims,
lawsuits and other legal actions brought by a third party against
the Indemnified Party to the extent caused by the acts or omissions
of such Commercial Distributor in connection with its distribution
of any of the work in a commercial product offering or in connection
with any services. The obligations in this section do not apply to
any claims or Losses relating to any actual or alleged intellectual
property infringement. In order to qualify, an Indemnified Party must:
(a) promptly notify the Commercial Distributor in writing of such claim;
and (b) allow the Commercial Distributor to control, and cooperate with
the Commercial Distributor in, the defense and any related settlement
negotiations. The Indemnified Party may participate in defense against
any such claim at its own expense.

8. GENERAL.

This License will not be construed as creating an agency, partnership,
joint venture, or any other form of legal association between or among
Cadence or any Recipient or Contributor.  If any provision of this License
is invalid or unenforceable under applicable law, it shall not affect the
validity or enforceability of the remainder of the terms of this License.
This License shall be governed by California law provisions (except for
its conflict-of-law provisions).
