In addition:

1.) Bunn warrants electronic circuit and/or control boards to be commercially free from defects in material and work-

manship for two years from the date of installation.

2.) Bunn warrants the compressor on refrigeration equipment to be commercially free from defects in material and

3.) Bunn warrants that the grinding burrs on coffee grinding equipment will grind coffee to meet original factory screen

sieve analysis for three years from date of installation or for 30,000 pounds of coffee, whichever comes first.

This warranty does not apply to any equipment, component or part that was not manufactured by Bunn or that, in

Bunn’s judgement, has been affected by misuse, neglect, alteration, improper installation or operation, improper mainte-
nance or repair, damage or casualty.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ANY OTHER WARRANTY, WRITTEN OR ORAL,

EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF EITHER MERCHANTABILITY
OR FITNESS FOR A PARTICULAR PURPOSE.

 The agents, dealers or employees of Bunn are not authorized to make

modifications to this warranty or to make additional warranties that are binding on Bunn. Accordingly, statements by such
individuals, whether oral or written, do not constitute warranties and should not be relied upon.

The Buyer shall give Bunn prompt notice of any claim to be made under this warranty by telephone at (217) 529-6601

or by writing to Post Office Box 3227, Springfield, Illinois, 62708-3227. If requested by Bunn, the Buyer shall ship the
defective equipment prepaid to an authorized Bunn service location. If Bunn determines, in its sole discretion, that the
equipment does not conform to the warranty, Bunn shall repair the equipment with no charge for parts during the warranty
period and no charge for labor by a Bunn Authorized Service Representative during the warranty period. If Bunn determines
that repair is not feasible, Bunn shall, at its sole option, replace the equipment or refund the purchase price for the equip-
ment.

THE BUYER’S REMEDY AGAINST BUNN FOR THE BREACH OF ANY OBLIGATION ARISING OUT OF THE SALE OF THIS

EQUIPMENT, WHETHER DERIVED FROM WARRANTY OR OTHERWISE, SHALL BE LIMITED, AS SPECIFIED HEREIN, TO
REPAIR OR, AT BUNN’S SOLE OPTION, REPLACEMENT OR REFUND.

In no event shall Bunn be liable for any other damage or loss, including, but not limited to, lost profits, lost sales, loss

of use of equipment, claims of Buyer’s customers, cost of capital, cost of down time, cost of substitute equipment, facilities
or services, or any other special, incidental or consequential damages.
