ALPOLIC ALUMINUM COMPOSITE MATERIAL 10-YEAR WARRANTY Project Name and Location: ( Manufacturer ), extends this special warranty ( Warranty ) to the property owner, Honda Dealership location (the Owner ) with corporate offices located at (actual location, city and state). The Warranty applies only to the Dealership Projects engineered, fabricated and installed by (Fabricator / Installer Name). Subject to the terms and conditions set forth in this Warranty, Manufacturer warrants that the Aluminum Composite Materials ( Materials ), furnished by Manufacturer for fabrication and installation in the system on the property commonly described as the Honda Dealership (the Property ) will not: (i) exhibit any visually observable deformation as a result of delamination of the aluminum skin from the core material due to manufacturing defects, or (ii) fail to comply with specification for manufacturing paints as set forth in Exhibit A hereto. In addition thereto, Manufacturer warrants to Owner that the coating applied or to be applied to the aluminum Materials purchased by Owner will not chalk in excess of a numerical rating of eight (8) measured in accordance with the standard procedures as outlined by the Standard Methods of Evaluating Degree of Chalking of Exterior Paint, ASTM D , and that such Materials will not fade or change in color in excess of five (5) color difference units, using ASTM D The product will not experience a loss of gloss that exceeds 40% when measured on vertical exposed surfaces that have been cleaned of external deposits and chalk and compared to the corresponding values measured on unexposed original coated surfaces. The gloss shall be measured at an angle of 60 degrees and in accordance with standard procedures as defined by ASTM D This Warranty will remain in effect for a period of ten (10) years from the date the Materials are installed on the Property. In the event all or part of the Materials fail to conform to this Warranty, Manufacturer will be responsible, at its sole option, for either repair to like-new condition or replacement of the nonconforming Materials. Such repair or replacement shall be at Manufacturer s sole cost and expense, including but not limited to all labor costs, with no charges to be incurred by the Owner. The remedies set forth in this Warranty shall constitute the Owner s exclusive remedies and Manufacturer s sole liabilities for breach of the Warranty set forth above. Manufacturer shall not be liable or responsible for any special, indirect, incidental, punitive or consequential damages in connection with the purchase or use of the Materials. Other than Manufacturer s standard coating warranty for the Materials, if any, Manufacturer makes no other warranties as to the Materials, written or oral, express or implied, including but not limited to any warranty of merchantability or fitness for any particular purpose, and no modification or change of this Warranty shall be effective unless it is made in a written document signed by an officer of Manufacturer. The Warranty period for any repaired or replaced Materials shall be for the remaining unexpired portion of the original Warranty period for the Materials. As color variances may occur between replacement Materials in comparison to the originally installed Materials, due to normal weathering and aging of the originally installed Materials, the parties expressly agree that this will not be indicative of a defect in either the replacement Materials or the originally installed Materials.

20 This Warranty covers only the particular defects described above and only if they arise during normal use and service. It does not cover any delamination attributable to causes or occurrences beyond Manufacturer s control, including but not limited to improper fabrication or installation of the Materials, exposures to corrosive atmospheres (such as those contaminated with acid rain, harmful chemicals or vapors), unreasonable use, misuse, physical abuse, accidental damage, vandalism, use of incompatible accessories, fire, flood, earthquake, lightning, ice, windstorms, other acts of God, wind-borne objects, building settlement, or structural failures (including walls and foundations), or the use of harmful cleaning compounds. The Owner and Manufacturer must agree to any exceptions to this Warranty in writing prior to acceptance of the Purchase Order. This Warranty is transferable and may extend to a purchaser of the original Owner of the premises for the balance of the term of the Warranty agreement. All notice given, pursuant to this Warranty, shall be in writing, in English, and sent by registered or certified mail, return receipt requested, postage prepaid, to: Manufacturer: Attn: END OF SECTION ALUMINUM COMPOSITE MATERIAL FACADE/CLADDING
