Description, Sample.

(1) Express warranties by the seller are created as follows:

(a) Any affirmation of fact or promise made by the sellerto the buyer which relates to the goods and becomes part of the basis of the bargain creates an express warranty that the goods shall conform to the

affirmation or promise.

(b) Any description of the goods which is made part of the

basis of the bargain creates an express

warranty that the goods shall conform to the

description.

(c) Any sample or model which is made part of the basis of

the bargain creates an express warranty that

the whole of the goods shall conform to the

sample or model.

(2) It is not necessary to the creation of an express warranty

that the seller use formal words such as "warrant" or "guarantee" or

that he have a specific intention to make a warranty, but an

affirmation merely of the value of the goods or a statement

purporting to be merely the seller's opinion or commendation of the

goods does not create a warranty.
