Plaintiff appeals from certain portions of the judgment rendered in a nonjury trial in which he sought recovery of damages for alleged breaches of a contract.
Plaintiff is a licensed liquor manufacturer’s agent .and defendant is a liquor manufacturer and importer. In his complaint plaintiff alleged: that in July, 1954, he and the defendant “. . . entered into an oral contract by the terms of *195 which defendant undertook and agreed to employ, and did employ, plaintiff as its exclusive selling agent ...” within a described territory in the southern portion of California, and to pay plaintiff as compensation a specified commission; that by the terms of the contract it was further agreed ”... that plaintiff should become and remain the sole and exclusive selling agent and should have and retain the exclusive right of sale of defendant’s said products in said territory as long as plaintiff should continue to use his best efforts to promote and solicit the sale of defendant’s products therein; that said oral contract was duly confirmed by defendant in its certain writing dated July 19, 1954 . . .’’a copy of which was appended as an exhibit to the complaint and is set out in full in the margin. 1
The complaint further alleged that plaintiff fully and faithfully performed the contract until May 31, 1955, but that on May 23, 1955, defendant wrongfully and without excuse or justification breached and repudiated the contract by writing him a letter reading as follows: ‘ ‘ This is to confirm our *196 advice to you that we are discontinuing you as a broker for the sale of our products effective May 31st, 1955.”
By the first cause of action of his complaint, plaintiff seeks recovery of the sum of $15,000 as damages for the “breaches and repudiation of said contract” and the further sum of $1,675 for unpaid commissions on orders accepted by defendant prior to May 31, 1955. By his second cause of action, plaintiff seeks an accounting from defendant with respect to sales made by defendant on or after May 31, 1955, in “plaintiff’s exclusive territory.” The third cause of action may be disregarded since the portion of the judgment allowing plaintiff compensation for the special services therein alleged is not questioned on this appeal.
It is to be specially noted that the letter of July 19, 1954, the writing by which, according to the complaint, the oral contract was “confirmed”—is entirely silent as to the term or duration of plaintiff’s employment. Defendant’s answer admitted “. . . a contract which was evidenced by the letter ...” and the trial court found that the parties “. . . entered into a written contract, a true copy of which is annexed to the complaint. ...”
At the trial, for the avowed purpose of proving an agreement concerning the duration of the agency, plaintiff sought to testify to certain conversations between himself and Mr. Morrell, defendant’s president, which preceded delivery of the writing. After reference had been made to one of these conversations, the direct examination of plaintiff proceeded as follows: “ Q. Now, in your discussion at that time with Mr. Morrill did you and he discuss the terms or conditions of the relationship you had in mind before this was delivered? A. Yes, we did. Q. Would you state what it was in regard, first as to the question of the duration of the relationship. Mb. Hall : That is objected to as calling for that which would vary *197 or add to the terms of an unambiguous written document and as being incompetent, irrelevant and immaterial. ’ ’
Defendant’s objection that the admission of such testimony would violate the parol evidence rule was sustained. Plaintiff made rather extensive offers of proof relative to the substance of said antecedent conversations and the circumstances attending the negotiation of the contract. Among other things, plaintiff offered to prove the following: (1) Plaintiff’s statement to Mr. Morrell to the effect that plaintiff would not be interested in the agency “. . . unless it were on a basis in which he would have an exclusive territory and be assured of a continuation as long as he performed his function adequately; that the product had been on the market and had been mistreated and it would take a minimum of three years to put it on a paying basis from the plaintiff’s point of view; . . .” (2) That both plaintiff and Mr. Morrell “. . . stated in the affirmative that it would take a long time to establish what was then not an unknown but a product that had been badly treated in the market, as they expressed it, there having been five preceding agents who attempted to put it over in the California market. . . . [T]hat it would take a minimum of three years to reach the point where sales would be compensatory, . . . that the contemplated gross sales would be between ten and twenty thousand cases per month by the end of that three-year period, and that only thereafter would the plaintiff have a chance to secure any real reimbursement. . . .” (3) That it was agreed between Mr. Morrell and plaintiff “. . . that a so-called promotion man, named Jetel, would be employed by the defendant for the purpose of assisting the plaintiff in pioneering this vodka group of products; that it was suggested by Mr. Morrill that Mr. Jetel be hired six months or later after the time of the conversation and the plaintiff suggested that it be done earlier and offered to Mr. Morrill the suggestion that he would forego one-half of his commission on the first 500 cases per month, which might be paid over to Mr. Jetel by the defendant and at all times that Mr. Jetel would be under the supervision of the plaintiff, though an employee of the defendant, ...”
The essence of plaintiff’s position on this appeal is stated as follows in his opening brief: 11 Substantively, it was and is plaintiff’s submission that he had alleged and could prove, first, that the contract should endure and continue as long as he used his best efforts to promote the sale and solicit sales of *198 defendant’s products in his exclusive territories; and, alternatively, the contract in the circumstances in contemplation was to endure for a reasonable time and could be unilaterally terminated only upon reasonable notice, such reasonable time and notice exceeding the ten months’ duration and the seven days’ notice herein.” Thus, the controlling question on this aspect of the case is whether it properly can be declared as a matter of law that the instant writing imports on its face to be such a complete expression of the whole agreement as to require exclusion of parol evidence offered to prove an additional contractual provision covering a matter as to which the writing is silent. (See 3 Williston, Contracts, p. 1821, § 633 (rev. ed. 1936).)
The parol evidence rule is a principle of substantive law that when the parties have embodied the terms of an agreement in writing, that writing becomes the contract of the parties and it may not be varied or supplemented by evidence of prior or contemporaneous negotiations of the parties.
(Estate of Gaines,
However, certain limitations upon the application of the parol evidence rule are well recognized. As stated in
Ellis
v.
Klaff,
As recently stated by our Supreme Court in
American Industrial Sales Corp.
v.
Airscope, Inc.,
In
Haggerty
v.
Warner,
In
Zinn
v.
Ex-Cell-O Corp.,
The foregoing California precedents, dealing as they do with contracts and factual situations closely similar to those here presented, point definitely to the conclusion that parol evidence should have been admitted for the purpose of ascertaining the intentions of the parties as to the term or
*201
duration of the contract at bar. Manifestly the agreement of the parties, express or implied, as to the duration of their relationship must be ascertained and read into the writing before us, because in this respect the written memorial is silent. (See
J. F. Millett Co.
v.
Park & Tilford Distillers Corp.,
The California precedents to which we have alluded are consistent with general authority. (See 3 Williston, Contracts, supra, p. 1819, § 633 et seq.; Rest., Contracts, §§ 228, 229, 239 and 240.) In the terminology of the Restatement, the writing at bar appears to constitute only a “partial integration” of the terms of the contract.
Respondent relies upon the rule stated in
Ruinello
v.
Murray,
It appears that plaintiff agreed not to handle any other line of vodka and that he did later decline another proffered line. Plaintiff offered to testify that the rate of his compensation was fixed at 50 cents a case (instead of $1.00) for the first 500 eases in order to provide compensation for Mr. Jetel, who was assigned to work with plaintiff in his efforts to produce ‘ ‘ fruitful and larger turnovers of our brand in Southern California to our mutual benefit.”
It is undisputed that the instant contract was modified by a subsequent executed oral agreement by which plaintiff’s territory was extended to northern California. Plaintiff testified as follows concerning his negotiations with Mr. Morrell in reference to said modification: “. . . then, I inquired as to the arrangements and he said they would be the same as
*202
they are down here, that as long as you did your job down here and up there both that you would go on as long as you did the job.” The parties acted upon this modification. Plaintiff’s testimony in reference to its terms could be construed either as an interpretation or as a modification of the original agreement with respect to the matter of its duration. Plaintiff’s testimony in this respect was received without objection and “. . . the admission of parol evidence to vary or add to a written instrument cannot be objected to for the first time in the appellate court.”
(Pao Ch’en Lee
v.
Gregoriou,
The contract which plaintiff alleged and offered to prove is not an ordinary contract of employment or agency in which the sole consideration on the part of the employee or agent consists of the rendition of services. Exclusive sales and distribution contracts such as that here involved generally express or imply obligations on both sides which are not present in the ordinary contract of employment. Williston devotes many pages of his text to the rules governing the duration and termination of this type of contract. (4 Williston, Contracts, p. 2847, § 1027A et seq. (rev. ed. 1936) and with reference to the situation ‘ ‘ [W] here the agreement contains no provision whatever for its termination ’ ’ he says: “Quite properly this has been held an enforceable executory contract, binding upon each party for a reasonable time. It is the settled law of agency that if the agent or employee furnishes a consideration in addition to his mere services, he is deemed to have purchased the employment for at least a reasonable period where the duration of the employment is not otherwise defined.”
Thus in the final analysis the issue as to the duration of the instant contract is one of fact to be resolved by a consideration of such available evidence as may be reasonably indicative of the intent of the parties, expressed or implied. (See
J. G. Millett Co.
v.
Park & Tilford Distillers Corp., supra,
123 P.Supp. 484 [liquor distributor’s contract indefinite as to duration found to be terminable only after a reasonable time and upon reasonable notice] ; and
Cf. Long Beach Drug Co.
v.
United Drug Co.,
Respondent relies strongly upon declarations in
Harrison
v.
McCormick,
Appellant’s second major contention involves the construction and application of the provision of the contract dealing with agent’s commissions: “We will compensate you with a brokerage commission, monthly, on all depletions of sales of our brand by all our distributors in Southern California, ...”
The complaint prayed for recovery of $1,657 on account of commissions due and owing appellant at the time of his discharge on May 31, 1955, and there is testimony in the record that during the period of plaintiff’s employment more than 1833% cases of defendant’s liquor products were sold to various Southern California distributors. However, not all of this merchandise was resold by the distributors. Plaintiff testified that at defendant’s request some 1445% eases of vodka were returned to defendant by the distributors for purpose of repackaging. Plaintiff also testified that 388 cases of vodka were retained by distributors despite defendant’s request for their return for repackaging. It is agreed that the only payment tendered to plaintiff for his services in selling said 1833 cases was by two checks totaling $320.50, which plaintiff retained uncashed at the time of trial.
*204 It is plaintiff’s contention that the quoted contractual provision means that plaintiff earned his commission when goods were sold to local distributors, and that the reference to “depletion of sales” meant that the commission due plaintiff did not become payable until the dealer disposed of the merchandise by resale. From this premise plaintiff here contends: (a) that the 388 cases “inevitably” had been depleted by the time of trial, more than a year later; and (b) that the 1445% cases were “depleted” by return to the manufacturer, or, alternatively, that defendant’s solicitation of the return of the 1445% cases constituted prevention of performance by the promisee, and was the equivalent of depletion.
The trial court construed the quoted portion of the contract to mean that commissions became due plaintiff only on
sales by the distributors during the period in which plaintiff was employed as defendant’s agent—that is to say, prior to May 31, 1955.
The only evidence in the record dealing with this provision of the agreement is plaintiff’s testimony as to his understanding of the meaning of the clause in question, which is directly contrary to the construction adopted by the trial court. This testimony is not reasonably susceptible of an inference which would support the judgment. Thus the trial court’s construction of the clause of necessity rests on the language of the writing alone. An appellate court is not bound to accept such a construction where it is not aided by extrinsic evidence.
(Cf. Union Oil Co.
v.
Union Sugar Co., supra,
As the learned trial judge suggested in his memorandum of decision, plaintiff’s right to commissions on merchandise sold to wholesalers prior to May 31, 1955, but not depleted from the wholesalers’ stocks on that date may be dependent upon the ultimate adjudication as to the duration of the contract and as to defendant’s right to terminate it. Moreover, we hold that defendant’s promise to pay plaintiff “.on all depletions of sales” is sufficiently ambiguous and uncertain that its meaning should be reexamined in the light of such parol evidence as may be received in aid of its proper interpretation upon a retrial.
