Notwithstanding anything herein to the contrary, any third party software (including firmware), whether open source, proprietary or otherwise (collectively, “Software”), that is embedded or included with any Product or otherwise provided by Seller is not being sold by Seller hereunder; instead, all such Software shall be separately licensed by Customer from the third party provider of such software and/or its licensors and is subject to all of the license terms and restrictions provided by such party.

Customer and Seller agree that all rights, title and interest, including trademarks, patent rights, copyright interests and other forms of intellectual property, in and to the Seller Work Products, Seller’s business methods, Seller’s Services and all related intellectual property of Seller are and shall remain the exclusive property of Seller.


CUSTOMER'S EXCLUSIVE REMEDY SHALL BE FOR DAMAGES, AND SELLER'S TOTAL LIABILITY FOR ANY AND ALL LOSSES AND DAMAGES ARISING OUT OF ANY AND ALL CAUSES WHATSOEVER (WHETHER SUCH CAUSE BE BASED IN CONTRACT, INFRINGEMENT, NEGLIGENCE, STRICT LIABILITY, OTHER TORT OR OTHERWISE) SHALL IN NO EVENT EXCEED THE PURCHASE PRICE OF THE PRODUCT AND/OR SERVICES IN RESPECT OF WHICH SUCH CAUSE ARISES OR, AT SELLER'S OPTION, THE REPAIR OR REPLACEMENT OF SUCH PRODUCT OR THE REPERFORMANCE OF SUCH SERVICES, AND IN NO EVENT SHALL SELLER BE LIABLE FOR INCIDENTAL, CONSEQUENTIAL, SPECIAL, INDIRECT OR PUNITIVE DAMAGES RESULTING FROM ANY SUCH CAUSE.

b) If Seller determines that its ability to supply the total demand for the Product or obtain any or a sufficient quantity of a material or component used directly or indirectly in the manufacture of the Product, is hindered, limited or made impracticable, Seller may allocate its available supply of the Product or such material or component (without obligation to acquire other supplies of any such Product, material, or component) among itself and its purchasers on such basis as Seller determines to be equitable without liability for any failure or delay of performance which may result therefrom.

c) Deliveries suspended or not made by reason of this section shall at Seller's option, either be canceled or the time for delivery shall automatically be extended for a period equal to the suspension period, without liability, but these Terms and Conditions shall otherwise remain unaffected.
