# ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT,
# MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient
# is solely responsible for determining the appropriateness of using
# and distributing the Program and assumes all risks associated with
# its exercise of rights under this Agreement, including but not
# limited to the risks and costs of program errors, compliance with
# applicable laws, damage to or loss of data, programs or equipment,
# and unavailability or interruption of operations.
#
# 6. DISCLAIMER OF LIABILITY
#
# EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT
# NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT,
# INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES
# (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON
# ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR
# TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF
# THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS
# GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH
# DAMAGES.
#
# 7. GENERAL
#
# If any provision of this Agreement is invalid or unenforceable under
# applicable law, it shall not affect the validity or enforceability
# of the remainder of the terms of this Agreement, and without further
# action by the parties hereto, such provision shall be reformed to
# the minimum extent necessary to make such provision valid and
# enforceable.
#
# If Recipient institutes patent litigation against a Contributor with
# respect to a patent applicable to software (including a cross-claim
# or counterclaim in a lawsuit), then any patent licenses granted by
# that Contributor to such Recipient under this Agreement shall
# terminate as of the date such litigation is filed. In addition, If
# Recipient institutes patent litigation against any entity (including
# a cross-claim or counterclaim in a lawsuit) alleging that the
# Program itself (excluding combinations of the Program with other
# software or hardware) infringes such Recipient's patent(s), then
# such Recipient's rights granted under Section 2(b) shall terminate
# as of the date such litigation is filed.
#
# All Recipient's rights under this Agreement shall terminate if it
# fails to comply with any of the material terms or conditions of this
# Agreement and does not cure such failure in a reasonable period of
# time after becoming aware of such noncompliance. If all Recipient's
# rights under this Agreement terminate, Recipient agrees to cease use
# and distribution of the Program as soon as reasonably practicable.
# However, Recipient's obligations under this Agreement and any
# licenses granted by Recipient relating to the Program shall continue
# and survive.
#
# IBM may publish new versions (including revisions) of this Agreement
# from time to time. Each new version of the Agreement will be given a
# distinguishing version number. The Program (including Contributions)
# may always be distributed subject to the version of the Agreement
# under which it was received. In addition, after a new version of the
# Agreement is published, Contributor may elect to distribute the
# Program (including its Contributions) under the new version. No one
# other than IBM has the right to modify this Agreement. Except as
# expressly stated in Sections 2(a) and 2(b) above, Recipient receives
# no rights or licenses to the intellectual property of any
# Contributor under this Agreement, whether expressly, by implication,
# estoppel or otherwise. All rights in the Program not expressly
# granted under this Agreement are reserved.
#
# This Agreement is governed by the laws of the State of New York and
# the intellectual property laws of the United States of America. No
# party to this Agreement will bring a legal action under this
# Agreement more than one year after the cause of action arose. Each
# party waives its rights to a jury trial in any resulting litigation.
