delivered the opinion of the court:
This appeal involves an agreement to pay a broker’s commission of *46,000 for producing an alleged unconditional offer to buy a building which would yield the seller a profit of *350,000. Plaintiff, Roland E. Casati, was a former officer and director of defendant, Aero Marine Management Company, Inc. (Aero). The circuit court, after a bench trial, entered judgment in favor of plaintiff.
On appeal the following issues are considered: (1) whether the finding that plaintiff procured an unconditional offer was against the manifest weight of the evidence, and (2) whether, if the finding was erroneous, plaintiff is nonetheless entitled to recovery on the basis of an anticipatory breach by defendants.
*3Plaintiff filed a complaint alleging an agreement was created on May 29, 1968, between Heritage Insurance Co. of America (Heritage) and plaintiff to supervise the construction of the Heritage Building (Building) in Lincolnwood, Illinois, to solicit prospective tenants for a certain set compensation, and, additionally, to solicit buyers for the Building entitling plaintiff to a “bonus.” The relevant portion of the agreement, which is addressed to plaintiff, reads as follows:
“Sale of Building: You shall solicit, in a manner consistent with your judgment, the sale of the Building to prospective buyers, and all such sales or offers to purchase or sell, shall be subject to the approval of Heritage. In the event you shall have submitted an unconditional offer in writing with not less than forty-eight hours to accept, which offer shall be sufficient to allow a profit to Heritage of not less than *350,000 before closing costs, pro-rations and the bonus agreed to be paid to you, then you shall be deemed to have earned the sale bonus herein agreed to be paid to you whether such offer is accepted or not, and such bonus shall be paid within twenty days after the date such offer is submitted, if not accepted by Heritage.”
The complaint further alleges the Building was sold to Aero, Heritage’s parent company, after an agreement between Aero and plaintiff was entered into on November 26, 1968. By this agreement, plaintiff waived any rights to a bonus deriving from this sale in exchange for Aero’s continuing to employ plaintiff under the May 29 agreement. The complaint further alleges plaintiff solicited prospective buyers including LaSalle National Insurance Co. (LaSalle) and submitted a written unconditional offer from LaSalle sufficient, pursuant to plaintiff’s contract, to allow a profit of *350,000. The complaint goes on to assert LaSalle was a purchaser, ready, willing and able and that Aero became hable to plaintiff for a bonus of *46,000. In the complaint, just prior to the prayer for relief, plaintiff sets forth, in paragraph 9, an “alternative” theory that defendants anticipatorily breached plaintiff’s “exclusive agency” to sell the Building as created by the May 29 and November 26 agreements. Defendants, in an amended answer, denied the allegations in paragraph 9 of the complaint.
At trial, defendants filed three motions in limine. One sought to exclude evidence on the issue of anticipatory breach on grounds plaintiff had not set forth his two causes of action in separate counts as required by the Civil Practice Act (Ill. Rev. Stat. 1971, ch. 110, par. 33(2)). A second sought judgment on the pleadings on this ground. A third sought to exclude parol evidence on the meaning of “unconditional” since no ambiguity had been pleaded. So far as we can determine from the record, the court ruled only on the motion in limine relating to parole evidence, denying that *4motion. The evidence presented by the parties was limited solely to the unconditional offer issue.
Limiting ourselves to the facts pertinent to our resolution of this appeal, we consider the following evidence. A major portion of the trial was devoted to establishing the completion date of the Building and its cost as of that date in order to determine whether LaSalle’s purported offer of *1,350,000 would allow Aero the required margin of profit of *350,000. A letter from Vincent Giacinto, the president of Aero, to the New York Life Insurance Co., the mortgagee of the Building, asserted that the Building was completed, including office space, on October 31, 1969. The stipulated exhibit indicates that the cost of the Building on that date was *943,457.51, including the cost of the land.
Offers of proof were made by various witnesses as to the meaning of “unconditional” in the contract. These witnesses alleged that, in the May 28, 1968, meeting of the board of directors of Heritage, at which this contract was discussed and approved, “unconditional” was inserted to obtain an “all cash offer,” i.e., one without financing. The court did not admit any of these offers, stating twice it saw nothing ambiguous about the term “unconditional,” although in its findings the court did state that the letter constituted a “cash offer.” The minutes of this meeting were, however, admitted into evidence and state that the word “unconditional” was inserted “to describe any written offer which might be received which would be sufficient to allow a profit to Heritage of not less than *350,000 * *
Documents admitted into evidence included the letter from LaSalle containing the purported offer, an attorney’s letter to the president of Aero advising him that LaSalle’s letter did not constitute an offer to purchase which was presented to the directors of Aero at their January 22, 1969, meeting, the minutes of the January 22 meeting at which the purported offer was rejected by Aero’s board of directors, and Aero’s letter of rejection to LaSalle. LaSalle’s letter containing the purported offer initially stated plaintiff had presented the Building to them for purchase and then set forth their knowledge of the details of ownership and construction. The letter then advised Aero that LaSalle was “willing to purchase said real estate and improvements upon completion of the construction work (except for completion of certain tenants’ work for space not then leased) at a price of *1,350,000. Tenants’ work which comes within said purchase price will be completed after closing as space is leased.” The letter continues on to require Aero to assign or cause to be assigned the benefits of a lease with Commonwealth Edison for parking space behind the Building and stated it was willing to negotiate a lease in the Building for Heritage as required by its mortgage agreement with New York Life Insurance Co. or substitute itself for Heritage as a tenant *5in the required space. Further, LaSalle “anticipated” the Building would be delivered unoccupied, that guarantees and warranties would be made available to LaSalle, and that sale commissions would be paid by Aero. The letter then stated:
“If the foregoing terms are acceptable to you, please notify the undersigned [the president of LaSalle] and we will immediately instruct our counsel to meet with you or your counsel, as you shall direct, for the purpose of drafting a full and complete contract acceptable to both parties.”
Terms for payment in escrow upon execution were then specified and a closing paragraph extended LaSalle’s “complete cooperation in furthering the transaction with a view towards as early a consummation as possible” requesting a response within three days.
The minutes of the January 22 meeting of Aero’s board of directors disclose that a resolution to sell the Building to LaSalle in accord with their purported offer was defeated, a resolution stating the letter did not constitute an “unconditional offer” and therefore should be rejected was adopted, and that a proposed amendment to this latter resolution authorizing plaintiff to pursue LaSalle to see if an unconditional offer could be procured was defeated. Two motions, one that plaintiff be instructed not to contact LaSalle further and one that the Building not be sold at the present time, were both withdrawn. Plaintiff’s resolution that LaSalle be informed in writing that Aero rejected their purported offer was passed and LaSalle was so informed.
Plaintiff made offers of proof that at the January 22 meeting the corporation attorney had warned the directors against including in the minutes their intention of withdrawing the Building from sale, which advice was, according to the offers, accepted. None of these offers were admitted into evidence. Defendants’ attorney, however, in the hearing on their motion for summary judgment admitted several times that the Building was withdrawn from “the market,” presumably in support of defendant’s then pending counterclaim based on an alleged breach of fiduciary duty by plaintiff as director.
During closing arguments, the court asked the parties if it could consider the issue of anticipatory breach without further evidence, to which inquiry both parties responded in the affirmative. The court remarked later in the arguments, “I don’t think there’s any question here that there was an anticipatory breach. It seems to me to be a foregone conclusion.” The trial court’s findings and judgment made no mention of the anticipatory breach issue.
I.
The initial issue to resolve is whether the finding that plaintiff procured an unconditional offer to purchase was against the manifest *6weight of the evidence. In the letter quoted above, LaSalle indicated it would instruct its counsel, upon affirmative response from Aero, to meet with Aero or its counsel for the purpose of working out an agreeable contract. Where the offer contemplates action or deliberations beyond acceptance in order to create a binding contract, it is an offer to negotiate rather than an offer to purchase. (1 Williston on Contracts §27 (3d ed. 1957); Dunlop v. Laitsch (1962), 16 Wis. 2d 36, 113 N.W.2d 551; Powell v. Beck (1962), 366 Mich. 627, 115 N.W.2d 317.) In our opinion the portion of the letter from LaSalle to Aero, just referred to, proposed an agreement to agree, indicating the letter was an offer to negotiate. Thus, it is unnecessary to determine whether the offer was unconditional and allowed a profit of *350,000. This disposition also renders separate consideration of the cases cited by the parties regarding the unconditional nature of the purported offer unnecessary.
II.
The second issue presented for review is whether plaintiff, in light of our holding the letter not to have constituted an offer to purchase, is nonetheless entitled to recovery on the basis of an anticipatory breach by defendants. Before this issue can be considered, it must be determined whether it is properly before us for review. Plaintiff’s complaint did not state the alleged cause of action for anticipatory breach in a separate count as required by section 33(2) of the Civil Practice Act (Ill. Rev. Stat. 1971, ch. 110, par. 33(2))1. Rather, plaintiff, used a one-count complaint to plead “alternative” theories. Paragraph 9 in itself is not sufficient to. state a complete cause of action but does state one when read in light of the rest of the complain2. Standing alone, paragraph 9 is defective in not having stated a complete cause of action either in itself or by incorporation by reference. Ill. Rev. Stat. 1971, ch. 110A, par. 134.
*7Defendants, in their answer and motion for summary judgment, responded to the merits of paragraph 9 rather than challenging the sufficiency of the complaint’s compliance with section 33(2) of the Civil Practice Act or any other portion of that Act. Only after the motion for summary judgment was denied and the case was set for trial did defendants file their three motions in limine3 seeking the exclusion of evidence on anticipatory breach and of parol evidence on the meaning of “unconditional” and judgment on the pleadings on the anticipatory breach issue. In these motions regarding anticipatory breach, defendants did challenge the plaintiff’s failure to comply, in his complaint, with section 33(2). It has long been the law in Illinois that defendants admit the sufficiency of the counts by pleading to the general issue and that motions to exclude evidence are not the proper vehicles for challenging the legal sufficiency of complaints. (Swift & Co. v. Rutkowski (1899), 182 Ill. 18, 23-24, 54 N.E. 1038; Illinois Central R.R. Co. v. Leiner (4th Dist. 1902), 103 Ill. App. 438, 447, affd, 202 Ill. 624, 67 N.E. 398.) In our opinion defendants have waived any defect in the complaint.4
Since defendants waived the defect in plaintiff’s complaint, nothing prevents this court from proceeding to the merits of the anticipatory breach issue, except the lack of a finding as to it in the trial court.
The record clearly indicates that the trial court, at the close of oral argument, discussed with counsel whether it should rule on the anticipatory breach issue. A fair reading of the colloquy suggests that counsel did not insist on a ruling, but rather were willing to wait for the court’s ruling on the unconditional offer issue. The trial court did not mention the anticipatory breach issue in its findings and judgment. Consequently, in our opinion, this case should be remanded to the trial court for the purpose of resolving the anticipatory breach issue consistent with the views expressed herein.
Since we are remanding, it may be appropriate to note, in regard to the rejected offers of proof as to the January 22 meeting that, where the object is to show that a contract has been abrogated, cancelled or surrendered, the question is one for the trier of fact and parol evidence is not barred from admission. Alschuler v. Schiff (1896), 164 Ill. 298, 304, 45 N.E. 424; Selimos v. Marinos (1st Dist. 1944), 323 Ill. App. 144, 149-51,54 N.E.2d 836.
We, therefore, reverse the judgment of the circuit court of Cook *8County and remand the cause to that court for further proceedings consistent with the views expressed herein.
Judgment reversed and remanded.
