Plaintiffs appeal from that portion of the trial court’s judgment which denied them recovery against defendant. Plaintiff Mosebach and defendant Blythe, co-owners of Elberon Elevator, had agreed in writing to either sell Elberon by November 15,1972 or, if a sale had not been effectuated by then, to discontinue operations by December 31, 1972. Mosebach and Blythe further agreed to jointly inject sufficient, capital into Elberon to cover Elberon’s various debts. Mosebach sought at trial to recover from Blythe a proportionate share of funds injected by him into Elberon claiming that Blythe had breached their agreement by not contributing an equal amount. The trial court found that the contract dates to sell or discontinue the business were conditions precedent; that Mosebach, who had the responsibility to discontinue the business, failed to comply with these conditions, thus rendering the remainder of the contract unenforceable; that money paid into Elberon by Mosebach was a loan; and that, because of the above findings, plaintiffs were not entitled to recovery against defendant. We affirm the trial court.
I. The scope of our review is subject to argument. Plaintiffs maintain that because the trial court received all evidence subject to objection and pursuant to consent by the parties involved, because the claims alleged in divisions II and III of plaintiffs’ brief are equitable in nature, and because plaintiffs’ division I is, in effect, seeking specific performance of a contract, which is an action in equity, the case was tried below in equity and appellate review is de novo. Defendant claims that because plaintiffs filed their action at law and stated at trial that the action was in both law and equity and because plaintiffs’ divisions I and III are clearly legal in nature, the action was tried at law and appellate review is not de novo. The trial court was uncertain whether the action was a legal or equitable one and did not state in its conclusions how the action had been tried.
We conclude that the action was one at law. “[T]he essential character of the cause of action and the remedy or relief it seeks, as shown by the allegations of the complaint, determine whether a particular action is at law or in equity . . . .” 1 C.J.S.

A case is reviewed as tried in the court below.
Atlantic Veneer,
II. The trial court found that times stated in the agreement were conditions precedent to the performance of the remainder of the agreement, that plaintiff Mosebach was primarily responsible for either selling the elevator by November 15, 1972 or for discontinuing the elevator’s business operations by December 31, 1972, that Mosebach, after failing to sell the elevator by the prescribed date, continued to solicit business opportunities for Elberon, and that Mose-bach’s failure to comply with the conditions *759 precedent rendered the remainder of the agreement unenforceable, thus relieving Blythe of further liability with respect to the agreement itself. Plaintiffs maintain the trial court erred as a matter of law in finding that the times in the agreement constituted conditions precedent, that conditions precedent are not a proper defense in this action where the defendant failed to affirmatively plead them, that if such conditions were present in the agreement, the defendant waived them by his own failure to perform, and that defendant, by his own conduct, modified the contract terms and extended the time limits.
Construction of a contract involves a determination of its legal effect and is always a matter of law for the court.
Owen Construction Co., Inc. v. Iowa State Department of Transportation,
We agree with the trial court that the establishment of dates for either the sale or discontinuance of the business constituted conditions precedent.
Conditions precedent are . . . those facts and events, occurring subsequently to the making of a valid contract, that must exist or occur before there is a right to immediate performance, before there is a breach of contract duty, before the usual judicial remedies are available.

We further find that substantial evidence existed to support the trial court’s determination that Mosebach was the party responsible for the business concerns of El-beron and that Mosebach, in failing to sell the elevator by November 15, should have wound down the business of Elberon as provided for in the agreement. Consequently, Mosebach, to recover, must have complied with the established conditions of the agreement. Proof of performance of a condition precedent is necessary to plaintiff’s cause of action.
Henschel v. Hawkeye-Security Insurance Company,
III. We disagree with the plaintiff’s argument that defendant Blythe waived the conditions of the agreement either by failing to sell or discontinue the business himself by the set dates or by his
*760
words and conduct following the December 31 deadline for the discontinuance of the business. A party to a contract who is entitled to the performance of a condition precedent may waive it either expressly or by conduct indicating waiver. 17A C.J.S.
Contracts
§ 491 at 690 (1963);
see also H. L. Munn Lumber Co. v. City of Ames,
Although a closer question, Blythe’s statement in January of 1973 indicating that he would be willing to extend the deadline for sale of the elevator to March 31, 1973 also did not constitute a waiver of the conditions in the agreement. Blythe made this statement after Mosebach had failed to sell or discontinue the business pursuant to the agreement. Because the terms of the agreement had not been met, the parties were still faced with the problem of disposing of the business. The fact that Blythe then agreed to a new selling deadline did not necessarily mean that he was waiving the unsatisfied conditions in the agreement. Rather, it could be said that he was agreeing to another selling deadline separate from the agreement itself. In the absence of stronger proof to the contrary, Blythe’s acquiescence in the March selling deadline represented an agreement separate from the original one and did not constitute a waiver.
IV. Nor can it be said that Blythe’s statement indicating acquiescence in a March selling deadline represented a modification of the original agreement. An executory contract may be modified by one party with the consent of the other.
Davenport. Osteopathic Hosp. Ass’n v. Hosp. Service, Inc.,
Here we find that no agreement existed between Mosebach and Blythe to modify the conditions specified in the original agreement. Blythe’s conduct alone is insufficient to prove the existence of such an agreement. Furthermore, Blythe’s words and conduct, which Mosebach relies upon to say a modification of the agreement took place, occurred after the expiration of the deadline dates specified in the original agreement. Because the conditions in that agreement had not been satisfied, Blythe was no longer liable under it. The agreement ceased to be executory and could not be modified. Mosebach cannot recover under a modification theory.
V. We further conclude that substantial evidence exists to support the trial court’s finding that money invested into Elberon by Mosebach constituted a loan rather than an injection of capital pursuant to the agreement. “To loan is to let a thing to another either gratuitously or for a reward.”
State v. Brandt,
In this case no formal contract was entered into between Elberon and Mose-bach specifying that money transferred by Mosebach constituted a loan, but this fact is not fatal since Mosebach oversaw the financial operations of Elberon. It is not illogical in such a case to conclude that the entry of the transaction by Mosebach into Elber-on’s books with interest attached sufficiently constituted a loan contract. Also, if Mosebach had meant these funds to be injection of equity capital made according to the agreement, it would seem unlikely that he would have entered such advancements into Elberon’s ledgers as interest bearing obligations. The fact that Mosebach received payments back also indicates that a loan had been made. The absence of concurrent interest payments is not controlling. We find that substantial evidence supports the finding that Mosebach intended his advancements of funds to be loans to Elberon. He, thus, becomes a creditor of Elberon and cannot collect payment pursuant to his written agreement with Blythe.
VI. Plaintiff Elberon’s third party beneficiary argument is without merit. Even if Elberon were deemed the third party beneficiary of the Mosebach-Blythe agreement, our finding above that Blythe is not liable under the agreement due to Mosebach’s failure to comply with the conditions also renders Blythe nonliable under the agreement to Elberon.
VII. Plaintiff Mosebach is, likewise, unable to collect from Blythe under the equitable doctrines of contribution, detrimental reliance or unjust enrichment. It has been said that equity will do justice where the remedy in the law is inadequate, 30 C.J.S.
