EXPENSES OF ANY NATURE INCURRED WITHOUT SELLER’S WRITTEN CONSENT, 
EVEN IF SELLER HAS BEEN NEGLIGENT, WHETHER IN CONTRACT, TORT OR OTH-
ER LEGAL THEORY. IN NO EVENT SHALL SELLER’S LIABILITY UNDER ANY CLAIM 
MADE BY BUYER EXCEED THE PURCHASE PRICE OF THE PRODUCTS.

7. User Responsibility.

 The user, through its own analysis and testing, is solely re-

sponsible for making the final selection of the system and Product and assuring that 
all performance, endurance, maintenance, safety and warning requirements of the 
application are met. The user must analyze all aspects of the application and follow 
applicable industry standards and Product information. If Seller provides Product or 
system options, the user is responsible for determining that such data and specifica-
tions are suitable and sufficient for all applications and reasonably foreseeable uses of 
the Products or systems.

8. Loss to Buyer’s Property.

 Any designs, tools, patterns, materials, drawings, confi-

dential information or equipment furnished by Buyer or any other items which become 
Buyer’s property, will be considered obsolete and may be destroyed by Seller after two 
consecutive years have elapsed without Buyer ordering the items manufactured using 
such property. Seller shall not be responsible for any loss or damage to such property 
while it is in Seller’s possession or control.

9. Special Tooling.

 A tooling charge may be imposed for any special tooling, including 

without limitation, dies, fixtures, molds and patterns, acquired to manufacture Prod-
ucts. Such special tooling shall be and remain Seller’s property notwithstanding pay-
ment of any charges by Buyer. In no event will Buyer acquire any interest in apparatus 
belonging to Seller which is utilized in the manufacture of the Products, even if such 
apparatus has been specially converted or adapted for such manufacture and notwith-
standing any charges paid by Buyer. Unless otherwise agreed, Seller shall have the 
right to alter, discard or otherwise dispose of any special tooling or other property in its 
sole discretion at any time.

10. Buyer’s Obligation; Rights of Seller.

 To secure payment of all sums due or oth-

erwise, Seller shall retain a security interest in the goods delivered and this agreement 
shall be deemed a Security Agreement under the Uniform Commercial Code. Buyer 
authorizes Seller as its attorney to execute and file on Buyer’s behalf all documents 
Seller deems necessary to perfect its security interest. 

11. Improper use and Indemnity.

 Buyer shall indemnify, defend, and hold Seller harm-

less from any claim, liability, damages, lawsuits, and costs (including attorney fees), 
whether for personal injury, property damage, patent, trademark or copyright infringe-

ment or any other claim, brought by or incurred by Buyer, Buyer’s employees, or any 
other person, arising out of: (a) improper selection, improper application or other mis-
use of Products purchased by Buyer from Seller; (b) any act or omission, negligent 
or otherwise, of Buyer; (c) Seller’s use of patterns, plans, drawings, or specifications 
furnished by Buyer to manufacture Product; or (d) Buyer’s failure to comply with these 
terms and conditions. Seller shall not indemnify Buyer under any circumstance except 
as otherwise provided.

12. Cancellations and Changes.

 Orders shall not be subject to cancellation or change 

by Buyer for any reason, except with Seller’s written consent and upon terms that will 
indemnify, defend and hold Seller harmless against all direct, incidental and conse-
quential loss or damage. Seller may change product features, specifications, designs 
and availability with notice to Buyer.

13. Limitation on Assignment.

 Buyer may not assign its rights or obligations under 

this agreement without the prior written consent of Seller.

14. Force Majeure. 

Seller does not assume the risk and shall not be liable for delay 

or failure to perform any of Seller’s obligations by reason of circumstances beyond the 
reasonable control of Seller (hereinafter “Events of Force Majeure”).  Events of Force 
Majeure shall include without limitation: accidents, strikes or labor disputes, acts of 
any government or government agency, acts of nature, delays or failures in delivery 
from carriers or suppliers, shortages of materials, or any other cause beyond Seller’s 
reasonable control.  

15. Waiver and Severability.

 Failure to enforce any provision of this agreement will 

not waive that provision nor will any such failure prejudice Seller’s right to enforce that 
provision in the future.  Invalidation of any provision of this agreement by legislation or 
other rule of law shall not invalidate any other provision herein. The remaining provi-
sions of this agreement will remain in full force and effect.

16. Termination.

 Seller may terminate this agreement for any reason and at any time 

by giving Buyer thirty (30) days written notice of termination.  Seller may immediately 
terminate this agreement, in writing, if Buyer:  (a) commits a breach of any provision of 
this agreement (b) appointments a trustee, receiver or custodian for all or any part of 
Buyer’s property (c) files a petition for relief in bankruptcy on its own behalf, or by a third 
party (d) makes an assignment for the benefit of creditors, or (e) dissolves or liquidates 
all or a majority of its assets.

17. Governing Law.

 This agreement and the sale and delivery of all Products here-

under shall be deemed to have taken place in and shall be governed and construed 
in accordance with the laws of the State of Ohio, as applicable to contracts executed 
and wholly performed therein and without regard to conflicts of laws principles. Buyer 
irrevocably agrees and consents to the exclusive jurisdiction and venue of the courts 
of Cuyahoga County, Ohio with respect to any dispute, controversy or claim arising out 
of or relating to this agreement. 

18. Indemnity for Infringement of Intellectual Property Rights.

 Seller shall have 

no liability for infringement of any patents, trademarks, copyrights, trade dress, trade 
secrets or similar rights except as provided in this Section. Seller will defend and in-
demnify Buyer against allegations of infringement of U.S. patents, U.S. trademarks, 
copyrights, trade dress and trade secrets (“Intellectual Property Rights”). Seller will 
defend at its expense and will pay the cost of any settlement or damages awarded in 
an action brought against Buyer based on an allegation that a Product sold pursuant 
to this Agreement infringes the Intellectual Property Rights of a third party. Seller’s 
obligation to defend and indemnify Buyer is contingent on Buyer notifying Seller within 
ten (10) days after Buyer becomes aware of such allegations of infringement, and Seller 
having sole control over the defense of any allegations or actions including all negotia-
tions for settlement or compromise. If a Product is subject to a claim that it infringes the 
Intellectual Property Rights of a third party, Seller may, at its sole expense and option, 
procure for Buyer the right to continue using the Product, replace or modify the Prod-
uct so as to make it noninfringing, or offer to accept return of the Product and return 
the purchase price less a reasonable allowance for depreciation. Notwithstanding the 
foregoing, Seller shall have no liability for claims of infringement based on information 
provided by Buyer, or directed to Products delivered hereunder for which the designs 
are specified in whole or part by Buyer, or infringements resulting from the modification, 
combination or use in a system of any Product sold hereunder. The foregoing provi-
sions of this Section shall constitute Seller’s sole and exclusive liability and Buyer’s sole 
and exclusive remedy for infringement of Intellectual Property Rights.

19. Entire Agreement.

 This agreement contains the entire agreement between the 

Buyer and Seller and constitutes the final, complete and exclusive expression of the 
terms of sale.  All prior or contemporaneous written or oral agreements or negotiations 
with respect to the subject matter are herein merged.

20. Compliance with Law, U.K. Bribery Act and U.S. Foreign Corrupt Practices 
Act. 

Buyer agrees to comply with all applicable laws and regulations, including both 

those of the United Kingdom and the United States of America, and of the country or 
countries of the Territory in which Buyer may operate, including without limitation the U. 
K. Bribery Act, the U.S. Foreign Corrupt Practices Act (“FCPA”) and the U.S. Anti-Kick-
back Act (the “Anti-Kickback Act”), and agrees to indemnify and hold harmless Seller 
from the consequences of any violation of such provisions by Buyer, its employees or 
agents.  Buyer acknowledges that they are familiar with the provisions of the U. K. Brib-
ery Act, the FCPA and the Anti-Kickback Act, and certifies that Buyer will adhere to the 
requirements thereof.  In particular, Buyer represents and agrees that Buyer shall not 
make any payment or give anything of value, directly or indirectly to any governmental 
official, any foreign political party or official thereof, any candidate for foreign political 
office, or any commercial entity or person, for the purpose of influencing such person 
to purchase products or otherwise benefit the business of Seller.
