WARRANTY DISCLAIMER. Gamco has made a diligent effort to provide product information and illustrate the products in this literature accurately; however, such information and
illustrations are for the sole purpose of identification, and do not express or imply a warranty that the products are MERCHANTABLE, or FIT FOR A PARTICULAR PURPOSE, or that the
products will necessary conform to the illustrations or descriptions. Except as provided below, no warranty or affirmation on fact, expressed or implied, other than as stated in the "LIMITED

PRODUCT SUITABILITY. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of products for certain purposes, which may vary from
those in neighboring areas. While Gamco attempts to assure that the products comply with such codes, it cannot guarantee compliance, and cannot be responsible for how the product
is installed or used. Before purchase and use of a product, review the product application, and all applicable national and local codes and regulations, and be sure that the product,
installation, and use will comply with them.
Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation or exclusion may not apply to you; (b) also, some jurisdictions do not allow a limitation on how long an implied warranty lasts, consequentially the above limitation may not
apply to you; and (c) by law, during the period of this Limited Warranty, and implied warranties of implied merchantability or fitness for particular purpose applicable to consumer products
purchased by consumers, may not be excluded or otherwise disclaimed.
