In this action to quiet title, defendant Lon V. Smith appeals from a judgment sustaining both special and general demurrers to his second amended answer, without leave to amend. On March 18, 1942, plaintiffs John F. N. Gavina and A.'F. Silveria, the owners-in fee of 2,209.50 acres of land in Kings County, granted to defendant for $100 the option of leasing the property for the purpose of operating for oil and gas. The option agreement set forth the terms and conditions on whieh the lease was to be executed. The form of lease was to be the form attached to the option agreement. Plaintiffs were to receive a rental of $1.00 per acre for one *503 year payable in advance. If drilling operations were not commenced within one. year from the date of the lease, the lessee could extend the period of the lease for four years by paying $1.00 per acre for each year. Plaintiffs’ royalty was to be one-eighth of all oil, gas or other hydrocarbon, substances produced. Surface rights were to be retained by plaintiffs for agricultural purposes to an extent that would not interfere with the lessee’s operations, and the lessee was to pay for any injury to livestock, trees, crops and improvements caused by oil and gas operations under the lease.' Upon the exercise by defendant of the option and the payment in advance to plaintiffs of a rental of $1.00 per acre for one year, plaintiffs agreed to execute and deliver a completed oil and gas lease on the attached form covering the 2,209.50 acres. The agreement provided that the money for the rental could be deposited in escrow with instructions that it be paid to the lessors upon receipt of the executed oil and gas lease. The money paid for the option was to be considered part payment of the rental. The defendant exercised the option and deposited $2,209.50 in escrow as specified. The form of lease attached to the option agreement was completed by the escrow-holder according to instructions and turned over to plaintiffs for their signatures. They failed to sign it or return it for the defendant’s signature, which was to be affixed after their own. They did not accept the money tendered, and they offer to return the $100 received for the option.
Plaintiffs contend that upon the exercise of the option defendant had merely an executory contract to make a lease; that although an executed lease would be a good defense to a quiet title suit, an executory contract that is not specifically enforceable is no defense to such a suit; and that the present contract is not specifically enforceable on the ground of lack of mutuality of remedy.
Whether the exercise of an option creates a lease or merely an executory contract to make a lease depends primarily upon the intention of the parties. It was the intention of the parties, expressed in the option agreement, to set forth therein and in the attached form of lease all the terms and conditions on which plaintiffs offered to lease the property. By exercising the option, defendant accepted plaintiffs’ offer and agreed to lease the property upon those terms and conditions. The requirement of a written lease was fully met, for
*504
the option agreement was in writing signed by the plaintiffs, and the option was exercised in writing by defendant. Nothing more was required to make a binding lease, so long as the parties did not intend that more should be done before the lease became effective.

v.
Jones,
It is settled in this state that an oil lease like the one in the present ease creates a profit a prendre and vests in the lessee an estate in real property
(Callahan
v.
Martin,
Even if it be assumed that upon the exercise of the option there was only an executory contract to make a lease, plaintiffs would not be entitled to have their title quieted against the claims of defendant under the contract. Plaintiffs could not complain that the lease was not executed when it was their breach of contract alone that prevented it from being executed. (Civ. Code, § 3517;
