Okla. Stat. tit. 12A, § 12A-2A-210: Express warranties

EXPRESS WARRANTIES

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

(a) Any affirmation of fact or promise made by the

lessor to the lessee which relates to the goods and becomes part of

the basis of the bargain creates an express warranty that the goods

will 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 will conform to the description.

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

basis of the bargain creates an express warranty that the whole of

the goods will conform to the sample or model.

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

that the lessor use formal words, such as "warrant" or "guarantee",

or that the lessor 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 lessor's opinion or commendation of the

goods does not create a warranty.
