OPINION
LACAGNINA, Judge.In this case, Casa Molina Restaurants (Casa Molina) entered into a rental lease agreement with Applied Technology Leasing Corporation (Applied Technology) for computer equipment for two of its restaurants.
Following execution of the agreement, Casa Molina made ten payments and then refused to make any more. Applied Technology accelerated the balance due and brought suit. Casa Molina counterclaimed for breach of contract and breach of implied warranty, and further alleged an ineffective warranty disclaimer and unconscionable contract and sought rescission. Upon motion for summary judgment, the trial court awarded Applied Technology the remaining balance due under the terms of the lease ($52,406.40) plus costs and attorney’s fees. From this judgment, Casa Molina appeals and argues the trial court erred in granting summary judgment because of the existence of material issues of fact regarding the agreement itself and the relationship between HLX Data Systems and Applied Technology. We disagree and affirm.
Applied Technology is engaged in the business of long-term equipment leasing. HLX Data Systems manufactured the equipment and sold it to Applied Technology. (Sometime in 1982 Applied Technology assigned its lease rental agreements to Computer Leasing, Inc.). The agreement covered a sixty-month period, with monthly rental payments. In the agreement, lessor disclaimed all warranties, express or implied and disclaimed any agent/principal relationship between themselves and the sales representative who arranged the transaction. If the equipment proved unsatisfactory, Casa Molina’s sole remedy was against HLX, the supplier, having been assigned all of Applied Technology’s *2defenses against HLX by the terms of the lease.1 Casa Molina was nevertheless obligated to continue making rental payments to Applied Technology, who retained ownership in the equipment. Casa Molina was not given an option to buy the equipment.
Upon default, the agreement granted Applied Technology certain remedies including, but not limited to, repossession, acceleration and recovery of the balance due or, in Applied Technology’s sole discretion, mitigation of damages by resale of the equipment without notice.2 Wayne Hall*3quist and Elias Molina personally executed the agreement as guarantors.
Casa Molina’s testimony, through depositions of Wayne Hallquist and Elias Molina, is consistent that the equipment never functioned satisfactorily and that some parts were never even made operational. They finally had to shut it down because they were losing too much business. The testimony is also consistent and uncontradicted by Applied Technology that Casa Molina was led to believe that HLX, the supplier, and Applied Technology were the same company. All negotiations included an HLX representative and Richard Palermo, but it was never represented to them that Applied Technology was separate from HLX. In fact, Wayne Hallquist testified he had never heard of Applied Technology until the deposition.
In this case, the trial court found after a review of all the evidence that Applied Technology was entitled to judgment as a matter of law by the express terms of the contract. Our review of the four corners of the contract, without any evidence of fraud, misrepresentation or mistake by Applied Technology toward Casa Molina, yields the same result. Isaak v. Massachusetts Indemnity Life Insurance Co., 127 Ariz. 581, 623 P.2d 11 (1981).
Both the terms of the contract and the facts which Casa Molina rely on indicate that their sole remedy is against HLX and/or Richard Palermo, the sales representative. Assuming, without deciding, that evidence of an agency relationship between Palermo/HLX and Applied Technology could have raised material fact issues, thereby defeating summary judgment, the trial court had no suchevidence before it and was justified in granting summary judgment.
The judgment in favor of Applied Technology in the amount of $52,406.40, plus the award of costs and attorney’s fees, is affirmed.
