ECONOMIC CONDITIONS AND TRENDS
It is understood and agreed that the basis for this Agreement is an extraordinary level of mutual trust and confidence between the parties, not only in matters or price, quality, and service relating to the quantities of Product purchased and sold hereunder, but also with respect to the accommodation of changes that may develop in the business environment or the pursuit of such mutual undertakings as may benefit either or both of the parties to this Agreement.  Moreover, the terms relating to quantity and price presume of continuation of economic conditions and trends now prevailing, including but not limited to levels of industrial production, tire demand, labor rates, energy costs, and foreign exchange relationships.  In the event that, in the view of either party, a significant change of any kind does occur which materially and significantly alters the value received by either party in this transaction, that party may, upon written notice of its election and reasons therefore, request that this Agreement be renegotiated and the other party will be obligated to respond within ten (10) days agreeing to enter into the renegotiation unless the request is formally withdrawn.  Neither party shall either unreasonably request such renegotiation or unreasonably withhold agreement to so renegotiate.

FAILURE IN PERFORMANCE
No liability shall result to EMCC/A or WPS/A from delay in performance or non-performance in whole or in part caused by circumstances reasonably beyond the control of the party affected, including but not limited to, acts of God, terrorist activity, transportation failure, breakdowns, equipment failure, shortage or inability to obtain Product or raw material for Product, or good-faith compliance with any governmental

order or request (whether valid or invalid).  Regardless, however, of the occurrence or nonoccurrence of any such circumstances, if supplies of Product, or feedstock for making Product, from any of EMCC/A’s existing sources are curtailed or are inadequate to meet EMCC/A’s own requirements and/or its obligations to its customers, EMCC/A’s obligation to deliver Product during such period shall be reduced to the extent necessary, in EMCC/A’s reasonable judgment, to apportion fairly among EMCC/A’s own requirements and its customers (whether under contract or not) such Product as received and as may be available in the ordinary and usual course of EMCC/A’s business from any existing sources of supply at the location(s) from which deliveries like those covered hereby are normally shipped.  EMCC/A shall not be obligated to purchase or obtain Product, or feedstock to make Product, to replace deliveries omitted or curtailed under this paragraph.

GOVERNING LAW
This Agreement shall be governed by the laws of the State of Texas.  Notwithstanding any other provision in this Agreement or any other document, neither this Agreement nor any other document shall constitute an agreement between EMCC/A and WPS/A which would cause EMCC/A to take any action that is in conflict with or prohibited by U.S. law.

ENTIRE AGREEMENT
This Agreement and the “Standard Terms and Conditions/Acknowledgement of Purchase Order” or invoice constitutes the complete and exclusive statement of the terms of agreement between EMCC/A and WSP/A and supersedes any and all agreements, representations and understandings, oral and written, made prior to signing and relating to the subject matter of this Agreement.
