This is an appeal by plaintiff from a summary judgment in favor of defendants. The question presented is whether the trial court was justified in granting the *232 motion of defendants for a summary judgment. The consideration of this question turns essentially upon whether a subordination clause in an agreement for the sale of real property is uncertain as a matter of law.
The Record
Plaintiff's second amended complaint for specific performance alleges that on January 4, 1962, plaintiff and defendants entered into a written agreement wherein defendants promised to sell to plaintiff and plaintiff promised to purchase from defendants certain described real property. It is further alleged that the agreement provides that plaintiff will pay no money down but will execute its promissory note payable to defendants for the amount of the purchase price with interest thereon at the rate of 6 per cent per annum payable semiannually; that the note is due and payable at the end of five years from its date unless defendants desire to have the note run for an additional five-year period in which event the interest shall continue at the same rate and the principal thereof shall be payable in five equal annual installments during the five-year period; and that said note is secured by a deed of trust to said property in which plaintiff is the trustor and defendants are the beneficiaries. It is also alleged that the purchase price of the land is $27,125, and that the Division of Highways of the State of California recently acquired comparable property for about one-half of the purchase price described therein; that in addition to the purchase price, plaintiff agreed to pay interest to defendants on any unpaid balance at the rate of 6 per cent per annum; that the purchase price mentioned in the agreement is equal to the value of the real property and therefore it would not be inequitable to enforce the terms of the agreement. A further allegation recites that plaintiff has fully performed under the agreement but defendants have failed and refused to perform thereunder and so advised plaintiff in writing on February 2, 1962. Plaintiff prayed for specific performance of the agreement, or, in the alternative, for damages caused it by reason of defendants ’ alleged breach.
Defendants filed their answer wherein they admitted the execution of an agreement with plaintiff (a copy of which is attached thereto and incorporated by reference), and their failure and refusal to perform said agreement. The answer alleges that defendants advised plaintiff of such refusal by letter dated February 2, 1962. In other respects defendants’ *233 answer generally denied the material allegations of the complaint.
Thereafter defendants moved for a summary judgment on the following grounds: (1) that the terms of the alleged contract sought to be specifically enforced are not sufficiently certain to make the precise act which is to be done clearly ascertainable; (2) that defendants have not received an adequate consideration for the contract; (3) that said contract is not, as to defendants, just and reasonable; and (4) that said action is without merit. In support of said motion defendants filed a declaration wherein each stated that she is one of the parties who signed the contract attached thereto marked “Exhibit A”; 1 that this contract is the one referred to in plaintiff’s second amended complaint; and that the facts stated are within her personal knowledge, and if sworn as a witness she can and will testify competently thereto.
Plaintiff filed a counteraffidavit, executed by Harry H. Hicks, Jr., the substance of which is as follows: that he is secretary-treasurer of plaintiff corporation; that as an officer of said and similar corporations engaged in land development and construction for the past 10 years, he was acquainted with the customs in the building industry, and particularly with respect to construction loans; that the practices and customs in the granting of construction loans, including the length of term of said loans and the interest rate are fairly standardized; that the amount of said loans is customarily 60 per cent of the value of the improvements to be erected, together with appraised value of the land upon which said improvements are to be placed; that the rate of interest is the prevailing rate in said locality at the time of making said loan and the length of the term of said loans customarily does not exceed five years; that the customs and practices in the making of said construction loans will be testified to at the time of trial.
The affidavit also avers that if the court believes that the subordination provision does, as a matter of law, make the contract uncertain, plaintiff is willing to delete this provision so that the deed of trust provided for therein will not contain a subordination clause; that said contract provides for no money down for the reason that defendants themselves did not wish to receive any down payment but desired as much interest as they could obtain; that the more money due on *234 the contract the larger the payments of interest would be; and for this reason alone no money was paid down to defendants; that defendants’ contention that said contract is unreasonable cannot be determined at this stage of the proceedings on the unilateral assertion of defendants or as a matter of law.
The motion for summary judgment was thereupon submitted ; and, pursuant to an order granting the same, a judgment in favor of defendants was signed and entered. On this appeal from said judgment plaintiff does not question the sufficiency of the moving affidavits, but asserts that the parties have raised issues which can be resolved only by presentation to, and a decision by, the trier of the facts.
It is apparent that defendants’ motion seeks a determination that as a matter of law the subject agreement is invalid on the ground that it is uncertain; that the consideration therefore is inadequate; and that it is not, as to them, just and reasonable. The supporting affidavits tender no factual issues but purport to serve merely as a vehicle to bring before the court the agreement in question. They do not, however, include the subject contract as an exhibit but refer to the copy attached to plaintiff’s second amended complaint. It is apparent, therefore, that the proper remedy for defendants was to move for a judgment on the pleadings since the court was merely called upon to determine the validity of the agreement as a matter of law from a consideration of the face of the pleadings. Accordingly, none of the basic principles controlling judicial action in granting or denying a summary judgment need to be restated here because we are not concerned with the sufficiency of the affidavits, but with the sufficiency of the second amended complaint to state a cause of action. It is well established, however, that where no triable issues are presented, and the sole remaining question is one of law, that question may appropriately be determined on a motion for summary judgment.
(Wilson
v.
Wilson,
It is apparent in the case at bench, from a reading of the trial court’s “Memorandum Decision,” that it considered the determination presented by the subject motion a question of law. It is there stated that the court “finds that the purported contract entered into is uncertain and unreasonable as *235 to sellers.” 2 We are relegated upon this review, therefore, to a determination of whether the trial court was justified in granting what is tantamount to a judgment on the pleadings. The provisions of the subject contract pertinent to our inquiry are set out in the footnote. 3
Is the Contract Uncertain?
Yes. The trial court predicated its determination of uncertainty essentially upon the subordination provision with respect to the deed of trust provided for in the contract, and concluded that “The only consideration and obligation of buyer provided in the contract is a note secured by a Deed of Trust against the property sold and this obligation may be subordinated to a construction loan without any provision being made in the contract for the amount of the loan, its term or the interest rate to which sellers’ Deed of Trust might become subject.”
The modern trend of the law is to favor the enforcement of contracts, to lean against their unenforceability because of uncertainty, and to carry out the intentions of the parties if this can feasibly be done.
(Burrow
v.
Timmsen,
Turning to the subordination provision in the instant case we find that it provides essentially as follows: ‘' Said Deed of Trust . . . will contain a subordination clause which will provide that Sellers . . . will agree that said Deed of Trust may be subordinated to a Deed of Trust securing a construction and/or take-out loan thereon. . . .” It is apparent that this provision does not state the amount of the construction loan which would be placed on the property, nor any of its terms, nor when it would become due, nor the rate of interest it would bear, nor the terms or conditions of the first deed of trust to secure such loan.

The rule underlying the foregoing cases is that when something is reserved for the future agreement of both parties, the promise can give rise to no legal obligation until such future agreement. “Since either party, by the very terms of the promise, may refuse to agree to anything to which the other party will agree, it is impossible for the law to affix any obligation to such a promise.”

Stanley, supra,
It is also contended by plaintiff that the subject subordination clause may be rendered certain by the admission of evidence of custom, and that therefore the trial court should have permitted the cause to proceed to trial so as to permit the introduction of evidence to interpret the contract. The principle relied upon is the rule that “ ' “ [t] he law does not favor but leans against the destruction of contracts because of uncertainty; and it will, if feasible, so construe agreements as to carry into effect the reasonable intentions of the parties if that can be ascertained. . . .” ’ ”

appears;
that the usage forms a part of the contract, and that evidence of usage is always admissible to supply a deficiency or as a means of interpretation where it does not alter or vary the terms of the contract, ’ quoting from

Was the Uncertainty Bemoved by Waiver of the Provisions of the Subordination Clause?
No.
Plaintiff also argues that even if the subordination clause is uncertain as a matter of law, it has eliminated the uncertainty by waiving the benefit of the clause. The purported waiver contained in Hick’s declaration has already been alluded to. The attempted waiver is ineffective for two reasons. First, it is no more than a conditional waiver of the subordination provision made on the eve of a summary judgment procedure. The cases cited by plaintiff in support of its proposition deal with an unconditional waiver, usually effective before the commencement of the trial. Plaintiff’s offer amounts to a radical alteration of a written contract inconsistent with the principle that the parties to a written agreement have a right to rely on the written contract as the complete and final memorial of their intentions. Secondly, if a party were permitted to waive defective provisions going to the essence of a contract, the court, in effect, would be allowing the unilateral creation of a new, different contract.
*243
A party to a contract cannot erase uncertainty therefrom by waiving such uncertainty and thereby restore its contractual validity.
(Klein
v.
Markarian, supra,
Was the “Belease Clause” Uncertain as a Matter of Law?
No. In its memorandum decision the trial court also announced that it found the “release clause” to be uncertain and unreasonable in equity on the ground that the provision placed the sellers in a position where they could be deprived of all choice lots or part of the lots without personal liability on the part of the buyer for the remainder. This conclusion was erroneous. The release clause is not uncertain as a matter of law. In the first place the agreement shows that the price of each lot was $875 with the exception of one lot, Lot 5 of Block 33, which was priced at $2,000. A reading of the agreement discloses that the buyer was obligated at all times to purchase all the lots and no lot would be released from the lien of the deed of trust without full payment of the price for that lot. Even after one or several lots were released, the sellers’ deed of trust would remain in force upon the remaining lots together with the sellers’ right to foreclose on those lots. 7 Aside from the $2,000 lot, the trial *244 court’s assumption that “choice lots” existed is belied by the fact that the purchase price for each lot is identical.
Adequacy of the Consideration
The briefs in the instant case have raised the issue of adequacy of the consideration. The lower court in its memorandum decision made no finding on this point, but merely stated the following: “The only consideration and obligation of buyer provided in the contract is a note secured by a Deed of Trust against the property sold. ...” Adequacy of consideration is a pleading problem and is so handled by the parties in the briefs. It was not, therefore, a proper subject of a motion for summary judgment. However, the lower court apparently decided the instant motion on the basis of the pleadings. We need not consider the susceptibility of the complaint to either a demurrer or a motion for judgment on the pleadings on the ground that adequacy of consideration was improperly pleaded, because no attack on that ground was made in the court below. Moreover, we need not discuss the issue of consideration because the contract is void and unenforceable due to the uncertainty and indefiniteness hereinbefore alluded to. 8
The judgment is affirmed.
Bray, P. J., and Sullivan, J., concurred.
Notes
Said exhibit, however, was not in £act attached to said declaration.
While such a memorandum may not be used to impeach or modify the judgment, it may be noted and may serve as a guide where the meaning of the judgment is unclear or to explain the process of reasoning by which the trial judge arrived at his findings.
(Mears
v.
Mears,
The written contract provides in pertinent part as follows: “Said note shall be secured by a Deed of Trust to the property hereinabove described in which Buyer will be the Trustor, Sellers the beneficiary, and a title company to be selected by Buyer, will be the Trustee. Said Deed of Trust will be in standard form and in addition will contain a subordination clause which will provide that Sellers, as beneficiary, will agree that said Deed of Trust may be subordinated to a Deed of Trust securing a construction and/or take-out loan thereon and shall also contain a release clause whereby any of the individual lots or any portion thereof hereinabove described may be released from the lien of the Deed of Trust upon payment of the purchase price, to-wit: Eight Hundred and Seventy-five ($875.00) Dollars per lot or the pro rata thereof if a portion of the lot is taken, or may likewise be released by the furnishing of substituted security by Trustor at not less than the equivalent value of the lot or lots or portion thereof being released, which said substituted security, however, shall be subject to Sellers approval. ’ ’
A hearing was granted by the Supreme Court. Althougli the decision of the intermediate court was overruled in other respects the Supreme Court was also of the opinion that the contract in question was not uncertain.
In King, it is stated: “In the absence of express conditions, custom determines incidental matters relating to the opening of an escrow, furnishing deeds, title insurance policies, prorating of taxes, and the like.” (P.589.)
There is nothing in the record to indicate that plaintiff’s offer to waive the subordination clause was accepted by defendants.
The agreement does not provide that the security is to be decreased in the same proportion as individual lots are released from the lien of the deed of trust.
The briefs have discussed the question whether plaintiff is entitled to damages for breach of contract in lieu of specific performance. At oral argument this ground of appeal was abandoned by plaintiff, it appearing that no cause of action for alleged damages was pleaded or stated.
