Boyer, 900 P.2d 1273 (Colo.App.1994), affirming the trial court’s entry of judgment pursuant to a jury verdict in favor of the respondent George Karakehian and against the petitioner Fred Boyer. The court of appeals held, inter alia, that the trial court correctly refused to instruct the jury on the statute of frauds, and that the trial court correctly allowed the respondent to introduce certain parol evidence. We affirm the court of appeals’ holding regarding the statute of frauds and reverse the court of appeals’ holding regarding the parol evidence.
I. '
On May 1, 1991, Boyer and Karakehian executed a written agreement entitled “Lease and Option” (the “Agreement”). The agreement provided that Boyer was to rent Karakehian’s house for the four month period from May 8, 1991 through September 8, 1991 for $1,750 per month. The Agreement also stated that Boyer was to provide Ka-rakehian a security deposit of $1,750. The Agreement further provided that Boyer had the option to purchase the property at any time during the term of the lease for the sum of $275,000.1 Boyer then gave Karakehian a check for $3,500, representing the first month’s rent and security deposit, and moved into the house.
On August 8, 1991, Karakehian informed Boyer that he wished to discuss closing a sale on the house. On September 5, 1991, Boyer sent Karakehian a rent check in the amount of $1,750 marked, “September rent,”2 along with a handwritten note stating: “George— Let’s get together Monday to discuss closing. Lunch would be a good time. — FYB.”
Boyer and Karakehian met for lunch on September 9, 1991. The parties are in dispute over what occurred at that meeting. Karakehian claims the parties set a closing date at the meeting, while Boyer maintains that he told Karakehian that he was unsure at that time whether he wanted to purchase the property. When Karakehian was subsequently unable to contact Boyer in order to set a closing date, Karakehian served Boyer with a notice to quit on September 27, 1991, terminating Boyer’s tenancy effective October 8, 1991. Karakehian also notified Boyer that he was retaining Boyer’s security deposit of $1,750.
Boyer then filed suit in county court demanding return of the security deposit, and Karakehian counterclaimed for breach of contract and promissory estoppel. The eases were consolidated and transferred to district court, where, after a trial, a jury rendered a verdict in favor of Karakehian on the breach of contract claim and against Boyer on the security deposit claim.
Boyer appealed, claiming, inter alia, that the trial court erred by refusing to instruct the jury on the statute of frauds, and that the trial court erred by allowing the respondent to introduce certain parol evidence. The court of appeals affirmed the trial court as to both of Boyer’s allegations of error.
With regard to the statute of frauds instruction, the court of appeals held that because the Colorado statute of frauds requires a writing signed by the party by whom the sale is to be made, the purpose of the statute is to protect the vendor, and the statute thus may not be asserted by the vendee. The court also held that because the Agreement did not specify any particular form in which the option was to be exercised, that Boyer’s oral exercise of the option constituted a valid acceptance. The court of appeals therefore held that the trial court correctly refused to instruct the jury on the statute of frauds.
With regard to the parol evidence, the court of appeals held that Karakehian’s testimony regarding the Agreement was properly admitted by the trial court. The court held that because Karakehian’s testimony did not contradict the terms of the written agreement, and because the testimony was permis
