Opinion
Introduction
Plaintiffs are eight local beer wholesalers terminated as distributors for defendant Beck & Co. They appeal from a judgment in favor of defendants entered after defendants’ motion for summary judgment was granted. Plaintiffs challenge the grant of summary judgment on each of the three causes of action charged by each plaintiff. Specifically, they contend: (1) plaintiffs presented sufficient evidence to create a question of fact as to whether the contract between Beck & Co. and each plaintiff included an implied requirement of good cause for termination; (2) sufficient evidence presented an issue of material fact as to whether defendants entered into a combination in restraint of trade adversely affecting industry competition; (3) since their hearsay evidence was admissible under the coconspirator exception to the hearsay rule, sufficient evidence supported a material question of fact as to whether defendants tortiously interfered with prospective business relations between plaintiffs and the “direct” or “master” wholesalers from whom they had previously purchased their Beck’s Beer.
In addition, plaintiff Rausser contends that: (1) its termination constituted an additional violation of the Cartwright Act’s prohibition of exclusive dealing contracts which may substantially lessen competition, and (2) it offered sufficient separate, admissible evidence to support a triable issue of fact as *1031 to whether defendants tortiously interfered with its business relations with independent third parties.
Statement of Facts 1
Beck & Co. is a beer manufacturer based in West Germany; its product, Beck’s Beer, is imported into the United States by Dribeck Importers. There is some conflict in defendants’ evidence as to defendant Jack Woodlief’s position with Beck & Co.: His answer to the complaint and one declaration states that he is western U.S. sales director for Beck’s Beer; for purposes of a motion to quash service of summons his declaration stated he was not an employee of Beck & Co. Defendant Jack Lewis is regional sales manager for Beck’s Beer, working under the supervision of Jack Woodlief.
There is also some conflict in the parties’ descriptions of the distribution network for Beck’s Beer, and the relationships between the parties. Defendants characterize the distribution network as a “three-tier system,” with the first tier being the brewer/manufacturer, the second the wholesaler/distributors, and the third the retailers. Plaintiffs characterize this network as a “multilayered system,” explaining that the brewer/manufacturer sells directly to a few large independent distributors (whom plaintiffs call master distributors) who in turn resell the beer at a profit to smaller independent wholesalers like plaintiffs. It is often the case that the large wholesalers (hereafter termed direct wholesalers) often sell their supplies of Beck’s Beer both to the subjobbing smaller wholesalers (hereafter termed local distributors) and to retail outlets, in competition with the local distributors.
When Beck & Co. enters into a distributor agreement with a wholesaler, it determines whether to ship directly to that wholesaler or to require that the distributor purchase its supplies of Beck’s Beer from the larger direct wholesalers. If the latter, Beck & Co. notifies its direct wholesalers of the authorized distributor. It is the direct wholesaler who determines what it will charge the local distributor, although Beck & Co. makes suggestions.
A distributor’s agreement, specifying the distributor’s territory, is required by law to be submitted to the Department of Alcoholic Beverage Control, along with the distributor’s current price postings for each brand of beer the distributor sells. (See Bus. & Prof. Code, §§ 25000, 25000.5.) It was defendant Jack Woodlief’s deposition testimony that in order to sell a brand of beer a distributor must have such an agreement on file at the *1032 Department, and that those items would remain on file after the manufacturer canceled the distributor’s agreement, so long as the wholesaler was legally contesting the termination.
Defendant Beck & Co. entered into a separate distributor agreement with each of the eight plaintiffs, all California beer distributors selling many brands of beer to retailers. Certain of plaintiffs’ representatives stated that their discussion with Woodlief regarding entering into this arrangement with Beck & Co. included no mention of contractual terms or conditions for termination. Harry Yamamoto of Towne Distributing declared he understood the distributors’ agreement form to be simply a legally imposed prerequisite to selling the Beck’s brand. While most of the declarations alluded to the existence of an unspoken understanding that good cause is required for distributor termination, Anthony Ferrigno of Consumers Distributing testified that at the time of the contract it was his understanding that either party could terminate the agreement at will, which understanding was later altered by information he received from other distributors at conventions. Jack Woodlief testified that he made it a practice to terminate distributors only for good cause.
Some time thereafter, Woodlief, acting as Beck’s western U.S. sales director, notified each of the plaintiffs that Beck & Co. would terminate its agreement in 30 days. Beck & Co. appointed new distributors to replace the terminated distributors in each territory.
After the effective termination date, when plaintiffs called their usual direct wholesalers to order Beck’s Beer, they were informed by most that they would no longer be sold Beck’s Beer. To explain this refusal plaintiffs offer declarations containing hearsay statements allegedly made by Jack Woodlief or Jack Lewis to the employees of these direct wholesalers to the effect that Beck & Co.’s representatives told them not to sell to the terminated local distributors. In addition, plaintiff Rausser points to a letter sent by Jack Woodlief to all his wholesalers stating that Rausser Distributing had been terminated and that selling Beck’s Beer to Rausser would violate state law. Jack Woodlief declares that the wholesalers were neither threatened nor coerced and defendants objected to the admission of the hearsay statements on the summary judgment motion.
Some plaintiffs were able to continue purchasing Beck’s Beer after their termination: Modugno Brothers bought supplies from plaintiff Sunny Distributors; Rausser bought from United Beverage until Woodlief allegedly told its representative to stop selling to Rausser; Rausser then bought from Santa Clara Valley Distributors until they too were terminated by Beck & Co.; it also bought Beck’s from Placer Beverage until Woodlief sent Placer *1033 a letter. Gianelli Distributing also purchased supplies from Santa Clara Valley Distributors. It was Woodlief’s belief that many earlier-terminated plaintiffs purchased Beck’s from the later-terminated Gianelli.
Jack Woodlief received complaints from one direct wholesaler, Markstein Distributing, that terminated subjobbers were selling Beck’s in its area, and he testified that Jack Lewis had received similar complaints from two replacement distributors, Premium Distributing and Basso Distributing, though Woodlief did not specify when these complaints were received. Woodlief says he told them there was nothing he could do about it. Woodlief also received complaints from new distributors Goings and Goethe that Rausser was selling Beck’s in their territories, which complaints prompted him to send out to Beck’s wholesalers the letter stating that Rausser had been terminated and that it would be illegal to sell to it. Woodlief also met with representatives of Santa Clara Valley Distributing on February 14, 1979, and told them that while it was legal to sell to the terminated distributors, it was creating chaos and “screwing up the market.” Woodlief also asked them if they planned to continue to sell to plaintiff Gianelli despite its termination by Beck’s, to which they replied that they didn’t know. Santa Clara Valley Distributors was thereafter terminated effective March 31, 1979, allegedly for low sales.
Woodlief testified that he neglected to send in the appropriate form notifying the Department of Alcoholic Beverage Control of the distributor terminations until December 1978, after the suit had been filed.
Statement of the Case
Plaintiffs filed their complaint on November 3, 1978, in Alameda County Superior Court, charging Beck & Co., Jack Woodlief, and Jack Lewis with breach of contract, arguing that defendants had breached an implied term of their contract requiring good cause for termination; intentional interference with prospective economic advantage; and violations of the Cartwright Act. Defendants answered on December 21, 1978, denying the relevant allegations and proposing four affirmative defenses: (1) defendants’ actions encouraged and promoted competition, (2) defendants’ conduct was justified because undertaken in protection of legitimate business interests, (3) the complaint failed to state facts sufficient to constitute a cause of action, and (4) the distributor agreements were unenforceable by reason of failure of consideration.
On March 19, 1979, Santa Clara Valley Distributors filed a complaint in the Superior Court of Santa Clara County against Beck & Co., Dribeck Importers, and Jack Woodlief, charging breach of contract, violations of *1034 the Cartwright Act, and intentional interference with prospective economic advantage. An answer thereto was filed on April 19, 1979.
Plaintiffs’ petition for coordination of the two cases was granted on November 2, 1979.
On February 2, 1981, defendants moved for summary judgment as to the claims 2 of the eight local distributors. An order granting summary judgment was signed September 22, 1981; interlocutory partial summary judgment was granted as to plaintiff Gianelli, since one of its claims remained. Final judgment was entered as to the other seven plaintiffs on October 14, 1981. Plaintiffs filed a timely notice of appeal October 30, 1981.
Discussion
Section 437c, subdivision (c) of the Code of Civil Procedure provides that a motion for summary judgment “. . . shall be granted if all the papers submitted show that there is no triable issue as to any material fact and that the moving party is entitled to judgment as a matter of law. ” Since plaintiffs challenge the lower court’s grant of summary judgment, this court must liberally construe the evidence contained in plaintiffs’ declarations and, viewing the admissible factual evidence in the light most favorable to plaintiffs, we must determine whether evidence was presented which, if true, would support a triable issue of fact as to each cause of action.

(1969)

Plaintiffs ’ Breach of Contract Claim
Plaintiffs contend that summary judgment was erroneously granted on their breach of contract claim because sufficient evidence supports a material question of fact as to whether the contract between Beck & Co. and each plaintiff included an implied requirement of good cause for termination. They argue that the distributor’s agreement is silent as to the issue, thus an implied requirement of cause is not precluded, and the question whether the circumstances give rise to an implied term is a factual one. They add that since the distributor’s agreement cannot be deemed integrat *1035 ed, parol evidence is admissible to amplify the contract terms. Finally, they assert that while sufficient factual evidence was presented supporting an implied-in-fact good cause requirement, such requirement should be implied in law in the interest of fairness, as it has been in the franchise and employment contract context.
A.
Whether the covenant of good faith and fair dealing implied in all contracts requires that a good cause termination requirement be applied as a matter of law.
It is well recognized in this state that a covenant of good faith and fair dealing is implied in all contracts, “that neither party will do anything which will injure the right of the other to receive the benefits of the agreement.”
(Comunale
v.
Traders & General Ins. Co.
(1958)
In recent years California courts have held, in certain limited circumstances, that breach of the covenant of good faith and fair dealing may give rise to a cause of action sounding in tort. Most commonly, it has been held that breach of an insurance contract by the insurer in effect breaches the covenant, giving rise to a tort cause of action. (E.g.,
Crisci
v.
Security Ins. Co.
(1967)
The covenant of good faith and fair dealing has also been extended to protect employees in situations where an individual is terminated as an employee after long term service for the employer. In
Cleary
v.
American Airlines, Inc.
(1980)
However, such cases carefully limit application of the covenant of good faith and fair dealing to situations in which there is a special relationship due to unequal bargaining power or a special element of reliance, whereas in an ordinary business contract where these special circumstances do not exist, we believe the covenant cannot be applied to specially protect one party by requiring cause for termination. (See,
Triangle Min. Co.
v.
Stauffer Chemical Co.
(9th Cir. 1985)
No case cited by plaintiffs holds that the implied covenant of good faith and fair dealing requires cause for termination of distributorship agreements in the absence of any express or implied agreement to that effect. The implied covenant of good faith and fair dealing in and of itself thus does not require a good cause for termination in this case.
B.
Whether appellants presented sufficient evidence of an implied understanding that good cause would be required for termination to support the existence of a triable issue of fact.
Plaintiffs contend that an implied-in-fact good-cause requirement for termination is contained in their contracts with Beck & Co. They argue that sufficient evidence was presented to support such an implied term.
*1037 The complete text of the very brief distributor’s agreement form signed by each plaintiff is as follows:
“It is hereby agreed between Beck & Co., of Bremen/Germany, brewers of Beck’s Beer, and_, distributor of said beer that the said distributor is authorized to distribute Beck’s Beer under its California Licensees) number_in the [County of]__Distributor’s authority hereunder is non-exclusive. This agreement will continue in effect unless and until terminated at any time after January 1, 1973 by thirty days written notice by either party to the other.”
Plaintiffs assert that the above writing can reasonably be interpreted to include an implied requirement of good cause for termination. Respondent-defendants argue that no parol evidence may be permitted to interpret or amplify its terms since it is unambiguous and constitutes an integrated writing.
Where parties have not agreed that a writing is the exclusive and final embodiment of their contract, the writing is unintegrated, and extrinsic or parol evidence will be admitted to determine the complete agreement.
(Masterson
v.
Sine
(1968)
The determination whether a writing constitutes an integrated agreement has in some cases been deemed “a question of law for the court,”
(Brawthen v. H & R Block, Inc.
(1972)
The trial court in this case made no findings in connection with its grant of the summary judgment motion. Thus the record fails to disclose *1038 whether the court determined the agreement to be “integrated.” If so, we believe the court’s determination to have been clearly erroneous.
Here, it is undisputed that the form agreement entered into by each of the plaintiffs was a standard one-paragraph document, not a negotiated instrument. Although there apparently were no terms discussed by the parties at the time of signing that were not contained in the distributor’s agreement, it is not unreasonable that an industrywide custom or usage could be considered part of that agreement.
Declarations by several plaintiffs averred that the short form document was required by the Department of Alcoholic Beverage Control and that it was not understood to set forth all the understandings and agreements concerning the terms of the distributors’ relationship with the brewery. The document itself lends credence to this interpretation as it is a preprinted form containing blanks for the name of the distributor and the territory to be covered. “If integration of the writing is not established as a matter of law, and the parol evidence is admitted, then the related questions of credibility of witnesses, and the parties’ intent, ordinarily become questions of fact for the jury. [Citations.]”
(Brawthen
v.
H & R Block, Inc., supra,
The evidence plaintiffs offered to demonstrate that the agreement was not integrated and that there existed an understanding of an implied-in-fact requirement of good cause for termination was primarily provided through the declarations of representatives of three distributors.
William Mizner of Sunny Distributors declared that there is an “understanding existent in the industry: that as long as a wholesaler is doing an adequate job . . . the brewery will continue to allow the wholesaler to handle the brand, . . . .” Mizner also declared that after the agreement was made, Woodlief told him that as long as Sunny Distributing did a good job and took care of the trade, Sunny would keep Beck’s brand. Mizner characterized the distributor’s agreement as merely a document that wholesalers had to file with the Department of Alcoholic Beverage Control, stating “these short form contracts in the beer industry are simply not meant to set forth all of the understandings and agreements of the terms of the distributor’s relationship with the brewery.”
Harry Yamamoto of Towne Distributing Co. declared that he did not recall any actual terms and conditions of the business arrangement being discussed other than that Towne would handle Beck’s Beer. His understanding of the distributor’s agreement was that it did not cover all terms and conditions of the relationship, and that its primary purpose was to enable *1039 the filing of the required document with the department. Yamamoto also declared that it is an accepted custom that a brewery will not pull a line of beer from a distributor except for a valid reason such as decreasing sales. Respondents point out that in his deposition Yamamoto stated that the custom in the industry preventing at will termination was due to fear of lawsuits, but Yamamoto averred that the referred-to testimony concerned situations of which he had heard where a brewery did not, for fear of a lawsuit, terminate a distributor whose sales were decreasing.
P. Frank Modugno of Modugno Brothers, Inc., declared that a good cause requirement for termination is a “recognized custom or practice prevalent in the California beer industry.”
Plaintiffs further point to Jack Woodlief’s deposition testimony that it was his practice to terminate distributors only for good cause. In other contexts evidence of such practice by an employer has been held to indicate the existence of an implied good cause requirement.
(Pugh
v.
See’s Candies, Inc., supra,
We agree with plaintiffs that the foregoing evidence is sufficient to establish that the agreement was not integrated and to create an issue of fact as to whether a good cause termination requirement was an implied term of the contracts. Consideration of the circumstances and industry practices at the time of the contract bears upon this determination.
Respondents note that one of the plaintiffs who entered into the distributor’s agreement testified that at the time of the agreement his understanding was that it could be terminated without cause. They also emphasize that there is no evidence of oral assurances made to plaintiffs at the time the distributorship agreement was signed concerning any cause requirement for termination. However, respondents do not offer any evidence specifically contradicting the industry custom and practice alleged by plaintiffs, doubtless in recognition that if they did so a dispute as to the practice in the industry would render it improper to grant summary judgment.
The question becomes, then, whether the specific allegations and assertions of an industry wide custom or understanding constitute admissible evidence as to what the parties’ understandings actually were. Although we have determined that the agreement was not integrated, we recognize that *1040 even where a writing is intended by the parties as a final expression of their agreement with respect to the terms included therein, those terms “may be explained or supplemented by course of dealing or usage of trade or by course of performance.” (Code Civ. Proc., § 1856, subd. (c).) 5
Thus, it appears that plaintiffs should be allowed to rely on a trade usage in the California beer industry even in the absence of any expression of such usage in the written agreement, and plaintiffs may be permitted to attempt to prove the existence of such usage at trial unless the proposed custom or trade usage contradicts the contractual terms.
The asserted usage of trade is that in the California beer industry good cause is required for the termination of a beer distributor’s agreement. The writing upon which defendants rely states “this agreement will continue in effect unless and until terminated at any time after January 1, 1973 by thirty days written notice by either party to the other.”
It has been held that an agreement which “may be terminated at any time by either party, by giving the other sixty days notice,” could reasonably be interpreted as referring only to the duration of the agreement and not the permissible reasons for its termination, since the clause does not expressly state whether good cause is a prerequisite.
(Sherman
v.
Mutual Benefit Life Ins. Co., supra,
Thus, the case at issue differs from those where proposed usage of trade has clearly contradicted the terms of the writing. (E.g.,
Weber
v.
Milpitas County Water Dist.
(1962)
Defendants rely upon
Alpha Distrib. Co. of Cal., Inc.
v.
Jack Daniel Distillery
(9th Cir. 1972)
In the instant case, we have concluded that the court erred in granting summary judgment as to the cause of action for breach of contract where plaintiffs provided evidence of trade usage and also of practice by the brewery which could have supported a finding that termination for cause was part of the distributorship agreement.
II
Cartwright Act Allegations
A.
Whether plaintiffs offered sufficient evidence to raise a material question of fact as to whether defendants violated the Cartwright Act. (Bus. & Prof. Code, §§ 16720, 16722, 16726.)
Plaintiffs claim that after their termination as distributors, defendants violated the Cartwright Act (Bus. & Prof. Code, § 16700 et seq.), which prohibits combinations in restraint of trade. Specifically, plaintiffs claim that Beck & Co., Jack Woodlief, Jack Lewis, and the direct wholesalers combined with local distributors who replaced plaintiffs to cut off plaintiffs’ supplies of Beck’s Beer, thus eliminating plaintiffs as a source of competition.
The Cartwright Act is patterned after the federal Sherman Antitrust Trust Act (15 U.S.C. § 1 et seq.), and cases interpreting the latter are applicable to the former.
(Marin County Bd. of Realtors, Inc.
v.
Palsson
(1976)
The United States Supreme Court has drawn two important distinctions central to distributor-termination cases. “First, there is the basic distinction between concerted and independent action—a distinction not always clearly drawn by parties and courts. Section 1 of the Sherman Act requires that there be a ‘contract, combination ... or conspiracy’ between the manufacturer and other distributors in order to establish a violation. 15 U.S.C. § 1. Independent action is not proscribed. A manufacturer of course generally has a right to deal, or refuse to deal, with whomever it likes, as long as it does so independently. [Citations.] Under
Colgate [United States
v.
Colgate & Co.
(1919)
The preliminary requirement of the antitrust law is that there be a “combination” or “conspiracy.” “[T]he refusal of a manufacturer to deal with a distributor can constitute a ‘combination’ in restraint of trade within the purview of the Sherman Act. [Citations.] While a producer may normally choose its distributors, cancellation of a distributorship for anticompetitive reasons violates the antitrust laws and is thus actionable. [Citations.] As noted in
Alpha Distrib. Co. of Cal., Inc.
v.
Jack Daniel Distillery
(9th Cir. 1972)
To survive a summary judgment motion plaintiffs were required to present sufficient evidence to demonstrate the existence of a disputed material issue of fact. As earlier noted, plaintiffs presented evidence that Woodlief and Lewis received complaints from newly appointed distributors and from one direct wholesaler about plaintiffs’ continuing to sell Beck’s Beer in their territories; further, Woodlief admitted that the letter he sent to the wholesalers advising them not to sell to plaintiff Rausser was in response to one of these complaints. It appears that the evidence presented *1044 by plaintiffs was sufficient to support a finding of a combination and concerted action by defendants and new distributors.
(1) No per se violation
However, sufficient facts must also have been presented to support the allegation that defendants’ conduct unreasonably restrained trade.
(Marin County Bd. of Realtors, Inc.
v.
Palsson, supra,
Application of per se rules of illegality

rather than the so-called “rule-of-reason,” which is the prevailing standard of analysis to determine whether a plaintiff has shown a combination or conspiracy in restraint of trade, is appropriate only when it relates to “conduct that is manifestly anticompetitive.”
(Continental T.V., Inc.
v.
GTE Sylvania, Inc.
(1977)
In recent years the courts have applied a per se rule to horizontal restraints with considerably greater alacrity than has been true with respect to apparently vertical restraints of the sort with which we are here con

(See, e.g.,
Ron Tonkin Gran Turismo
v.
Fiat Distributors
(9th Cir. 1981)
It warrants mention, at this juncture, that per se violations have been found in several cases involving ostensibly “vertical” restrictions that were determined to be “primarily horizontal in nature.” Thus, in
Cernuto, Inc.
v.
United Cabinet Corp., supra,
Similarly, in
Com-Tel, Inc.
v.
DuKane Corp.
(6th Cir. 1982)
Plaintiffs’ effort to characterize the instant case as factually analogous to
Cernuto
and
Com-Tel
is unavailing. Though there is evidence that Beck & Co., through its agents Woodlief and Lewis, received and acted in response to complaints by distributors in competition with plaintiffs, such evidence is hardly dispositive of the issues of the purpose and effect of the restraint, which are, of course, the critical issues. “Restraints solicited by a distributor but implemented by a manufacturer are not automatically per se violations. [Citation.] Restraints of this type come within the per se rule only if they ‘clearly had, or [were] likely to have, a pernicious effect on competition and lacked any redeeming virtue. [Citations.]’ ”
(General Business Systems
v.
North Am. Philips Corp., supra,
*1047 In order to sustain a group boycott theory of per se illegality with respect to restraints that are vertically imposed, there must be a showing that the restraint imposed by the manufacturer was not only conceived of and initiated by those in direct competition with the plaintiff, but that those competitors used their economic power or position to influence the manufacturer to act, not for its own advantage, but solely for the advantage of those competitors. Such a showing cannot here be made.
Even indulging the assumption that the restraint imposed by Beck’s was prompted by complaints from plaintiffs’ competitors, there is no evidence that Beck’s was compelled to act on those complaints because of an exertion of economic power. Nor is there evidence that Beck’s acted solely or even primarily for the benefit of plaintiffs’ competitors rather than for its own benefit. Finally, and perhaps most significantly, there is no evidence that the challenged restraint had any “pernicious effect on competition and lacked any redeeming virtue.”
Clearly, “conspiracy among dealers and their supplying manufacturer for the purpose of retail price maintenance that would benefit the dealers” would be “horizontal in nature and
per se
illegal.”
(Donald B. Rice Tire Co.
v.
Michelin Tire Corp.
(4th Cir. 1981)

(2) “Rule of reason” analysis
Generally, in determining whether conduct unreasonably restrains trade, “[a] rule of reason analysis requires a determination of whether . . . its anti-competitive effects outweigh its pro-competitive effects.”
(Columbia Broadcasting Sys.
v.
Am. Soc. of Composers
(2d Cir. 1980)
While it is undisputed that to prevail at trial under a rule of reason, plaintiffs must prove that the alleged anticompetitive effects on intrabrand competition outweigh any pro-competitive effects on interbrand competition of the restraint, the parties dispute the quantity of evidence sufficient to survive summary judgment under a rule of reason analysis. Plaintiffs contend that defendants did not sustain their burden under Code of Civil Procedure section 437c, and summary judgment was erroneously granted because defendants failed to demonstrate that there was no factual dispute concerning whether pro- or anticompetitive effect weighed stronger. Plaintiffs argue that to survive summary judgment “it is sufficient to show that competition was reduced in the market for Beck’s Beer,” and that they did so by showing the competition was reduced by the removal of them as competitors. Plaintiffs reason as follows:
“After
plaintiffs’ terminations as authorized distributors but
before
defendants acted to cut off plaintiffs’ supplies, a retailer could obtain Beck’s Beer from three sources: The master wholesaler, the new authorized local wholesaler, and from plaintiffs.
After
Beck & Co. cut off plaintiffs’ supplies, this number was
reduced
to two: The master wholesaler and the new authorized local wholesaler. This reduced the number of competitors for a given retailer’s business. As pointed

While it is true that there is generally “a greater reluctance to uphold a grant of summary judgment when the rule of reason is the appropriate standard . . . . ”
(Ron Tonkin Gran Turismo
v.
Fiat Distrib., supra,
Thus utilizing the rule of reason analysis the trial court properly sustained summary judgment as to plaintiffs’ Cartwright Act claims.
B.
Whether plaintiff Rausser Distributing presented sufficient evidence to raise a question of material fact as to whether defendants violated the Cartwright Act’s exclusive dealing provision. (Bus. & Prof. Code, § 16727.)
plaintiff Rausser claims that the trial court erroneously granted defendant’s summary judgment motion on Rausser’s separate antitrust claim, despite the fact that it was sufficiently pled, and the defendants did not address the merits of this claim on their summary judgment motion. 10
*1050 The complaint includes a paragraph alleging a violation of California Business and Professions Code sections 16720 and 16727 and Rausser claims it was terminated because it refused to cease handling Beck’s competitors’ products, Heineken and St. Pauli Girl Beer. The complaint incorporated a letter from Woodlief to Rausser asserting that the termination was due to the incompatibility of handling Heineken and St. Pauli Girl with Beck’s Beer within the same distributorship. Woodlief’s deposition admits that Rausser was terminated for this reason, and that Rausser was told of this. Plaintiffs assert that the above establishes a violation of section 16727. Plaintiffs emphasize that since the claim was not addressed by defendants’ summary judgment papers, the trial court summary adjudication of this claim is unsupportable.
Section 16727 provides: “It shall be unlawful for any person to . . . contract for the sale of goods, ... on the condition, agreement, or understanding that the . . . purchaser thereof shall not use or deal in the goods ... of a competitor or competitors of the . . . seller, where the effect of such . . . contract for sale or such condition . . . may be to substantially lessen competition or tend to create a monopoly.”
Section 16727 incorporates into the Cartwright Act the essential provisions of section 3 of the federal Clayton Act (15 U.S.C.A. § 14), and federal interpretations of Clayton Act section 3 are persuasive in interpreting Business and Professions Code section 16727. (Chicago Title Ins. Co. v. Great Western Financial Corp., supra, 69 Cal.2d 305, 315.)
It is plaintiffs’ contention that conditioning retention of Rausser as distributor on Rausser’s agreement to drop certain other brands constitutes a violation of section 16727. This is not the case.
*1051
“ ‘The anti-trust laws do not prohibit a manufacturer or distributor from selecting dealers who will devote their time and energies to selling the former’s products and a manufacturer is not compelled to retain dealers having divided loyalties adverse to the interests of the said manufacturer or distributor.’”
(Timken Roller Bearing Company
v.
F.T.C.
(6th Cir. 1962)
Thus, Rausser’s allegation that defendants terminated his distributorship does not state a claim under section 16727 and the trial court’s grant of summary judgment as to all plaintiffs on the Cartwright Act claims was proper.
Ill
Intentional Interference With Prospective Economic Advantage Claim
A.
Whether plaintiffs presented sufficient evidence to withstand summary judgment on their claim of intentional interference with prospective economic advantage.
All plaintiffs contend that summary judgment was erroneously granted on their claim of tortious interference with prospective economic advantage, as the record contained sufficient evidence supporting a question of fact as to whether defendants intentionally disrupted the business relationship between plaintiffs and the independent direct wholesalers who had previously supplied plaintiffs with Beck’s Beer. Plaintiffs submit that the direct wholesalers must be considered independent third parties for purposes of this *1052 cause of action, and assert that questions of fact exist as to whether defendants interfered with this relationship and whether such interference was privileged by virtue of defendants’ relationship with the direct wholesalers.
Plaintiffs further contend that, despite its hearsay character, the evidence presented was sufficient, as the proffered hearsay statements were admissible under Evidence Code section 1223, the coconspirator exception to the hearsay rule.
Essentially, defendants argue that summary judgment on this cause of action was proper as there was no admissible evidence of interference; the relationship between defendant Beck & Co. and the wholesalers was such that there was no independent third party relationship between wholesalers and plaintiffs with which to interfere. In any event, defendants claim, their actions were privileged.
Initially, defendants question whether plaintiffs presented sufficient admissible evidence to support their intentional interference claim, arguing that only inadmissible hearsay supports the cause of action. Code of Civil Procedure section 437c provides that declarations shall set forth
admissible
evidence, and this excludes properly objected to hearsay statements.
(Rickel
v.
Schwinn Bicycle Co.
(1983)
Plaintiffs argue that the contested hearsay statements, allegedly made by Woodlief and Lewis to certain representatives of the direct wholesalers, fall within the coconspirator exception to the hearsay rule, Evidence Code section 1223. 11 They assert that as long as they present independent evidence connecting the direct wholesalers to the conspiracy to eliminate plaintiffs’ sources of supplies of Beck’s Beer, section 1223 may be applied to admit the contested hearsay. They therefore point to (a) the letter sent by Woodlief to Santa Clara Valley Distributors and the other direct wholesalers and (b) admissions by Woodlief that Lewis and he received complaints from at least one direct wholesaler about sales by terminated distributors, and that they approached Santa Clara Valley Distributors, the apparent source *1053 of the “bootleg” sales, to attempt to convince them to stop selling to unauthorized distributors.
It appears that the statements by Woodlief or Lewis to the wholesalers are sufficient indicia of a conspiracy to permit application of section 1223. However, the hearsay statements create a multiple hearsay problem. The statements were then conveyed by those wholesalers to the plaintiffs, and this second level of hearsay is not covered by section 1223, which requires that a coconspirator’s admission must be made in furtherance of the conspiracy. Since the wholesalers’ statements to the plaintiffs were clearly not in furtherance of the alleged conspiracy, the hearsay contained in plaintiffs’ affidavits remains inadmissible.
The evidence remaining to support plaintiffs’ claim of intentional interference with their source of supply of Beck’s is as discussed above: (1) the letter sent to the wholesalers regarding sales to Rausser, and (2) the admissions by Woodlief that Lewis and he received complaints regarding sales by unauthorized distributors, and that they attempted to convince the owners of Santa Clara Valley Distributors to stop selling Beck’s to unauthorized distributors. While this evidence is slim support for a claim of intentional interference with prospective economic advantage, it may be considered sufficient to create a triable question of fact and to withstand summary judgment.
In order to prove their cause of action plaintiffs must show “the existence of either a contractual relationship or a prospective business relationship advantageous to them, that defendants had knowledge of the advantageous relationship, that defendants intentionally or negligently induced the breach of the relationship, that the acts or conduct of the defendants were wrongful, and proximately caused plaintiff’s injury and damage by interfering with the relationship causing a business loss.

Defendant Beck & Co. contends that its actions were privileged and therefore justified. In California it is clear that justification is an affirmative defense which must be pleaded by the defendant.

The foregoing analysis strongly supports plaintiffs’ contention that the existence of a privilege is a question of fact. Defendants counter that privilege in this case is a matter of law because defendants’ alleged unlawful conduct occurred

the effective dates of plaintiffs’ termination as distributors. For this proposition defendants cite

(1958)
We agree with plaintiffs that California Beverage is not pertinent to the facts of this case in that the subject of the claimed interference here is the relationship between plaintiff and its suppliers whereas in California Beverage, the interference was between plaintiff and its purchasers. As plaintiffs aptly point out, California Beverage does not discuss the issue of interference with suppliers “because the distributor there purchased its supply directly from the defendant, and not from any independent third party. The defendant could therefore terminate the distributor’s supply without involving any third party. Thus, if Beck & Co. had limited itself to having Wood-lief and Lewis go around to the retail accounts and encourage them to buy Beck’s Beer from the replacement wholesalers rather than plaintiffs no actionable interference would necessarily arise. In that situation, the plaintiffs could still compete with their replacements for the business of the particular retail account. However, when as here the interference operates at the sup *1056 ply level the effect thereof is to eliminate this competition. This is one of the factual circumstances that makes the question of defendants’ privilege or justification an issue for the fact finder and markedly differentiates this case from California Beverage. ” As defendant Beck & Co. asserts no legally recognized privilege, other than to boldly assert that interference with suppliers is justifiable, we are compelled to conclude that this cause of action contains a disputed issue of material fact regarding the existence of privilege.
The question remains whether Beck & Co.’s termination of Santa Clara Valley Distributors may have constituted an intentional interference with plaintiffs’ relations with that wholesaler. Defendants assert that termination of Santa Clara Valley Distributors was not itself interference as defendants were free to terminate their relationship with their wholesaler without giving rise to a cause of action. However, the cases relied upon by defendants,

Whether plaintiff Rausser presented sufficient evidence to withstand summary judgment on its claim of intentional interference with prospective economic advantage.
Plaintiff Rausser contends that by sending the letter to the direct wholesalers incorrectly informing them that it was illegal to sell to Rausser, defendants intentionally interfered with its business relations. Further, Rausser contends that a material issue exists as to whether Woodlief had the authority to terminate distributors. We believe that our analysis of the prior issue is determinative of Rausser’s contention that by the letter sent to wholesalers defendants tortiously interfered with its prospective economic advantage. It appears clear that disputed questions of fact exist regarding the relationship and character of the wholesalers as possible third parties, the question of causation, 14 and the question of privilege. 15
In light of Woodlief’s apparently inconsistent statements prior to the summary judgment motion that he was not an employee or agent of Beck & Co., we believe the issue of Woodlief’s authority to terminate Beck & Co.’s contract with Rausser presents a disputed issue of fact. However, it is questionable that this issue has any bearing upon the propriety of the grant of summary judgment as to the intentional interference claim, since it does not appear to be material to that claim. There is no dispute that plaintiffs were *1058 in fact terminated. Moreover, it appears certain that if indeed Woodlief did not have the authority, Beck & Co. by their subsequent actions, including their concessions in the instant case regarding Woodlief’s authority, have ratified Woodlief’s actions.
The judgment is reversed and the cause remanded to the trial court for further proceedings in accordance with the views expressed herein.

(1968)
Provisions of the California Uniform Commercial Code, although not determinative in this situation, are illustrative of the admissibility of evidence of trade usage to interpret contract terms. California Uniform Commercial Code section 1205 provides that “[a] usage of trade is any practice . . . having such regularity of observance in a place, vocation or trade as to justify an expectation that it will be observed with respect to the transaction in question. The existence and scope of such a usage are to be proved as facts.” Section 1205 continues that a usage of trade may supplement the terms of an agreement, unless- the usage is inconsistent with the express terms of the writing. (See also Corbin, Contracts (1950) § 528 and (1960) § 556.) Similarly, California Uniform Commercial Code section 2202 permits parol or extrinsic evidence of a usage of trade to explain or supplement—but not contradict—a writing intended by the parties as a final expression of their agreement. This section has been held to permit introduction of evidence of trade usage even where there is no proof of ambiguity of terms of the writing.

“It is important to distinguish between ‘horizontal’ restraints,
i.e.
agreements between competitors at the same level of market structure, and ‘vertical’ restraints,
i.e.
combinations of persons at different levels of the market structure, such as manufacturers and distributors. [Citation.] Horizontal restraints alone have been characterized as ‘naked restraints of trade with no purpose except stifling competition,’ [citation]; and, therefore
per se
violations of the Sherman Act. On the other hand, while vertical restrictions may reduce intrabrand competition by limiting the number of sellers of a particular product, competing for a given group of buyers, they also promote interbrand competition by allowing a manufacturer to achieve certain efficiencies in the distribution of its products [citation]. They are, therefore, to be examined under the
rule of reason
standard.”

“Vertical restrictions promote interbrand competition by allowing the manufacturer to achieve certain efficiencies in the distribution of his products.

The parties’ briefing centers almost entirely upon the issue of whether Rausser sufficiently pleaded this violation in his complaint and whether the court erred in failing to consider this claim on the summary judgment motion. Although we have determined to address the merits, as we believe summary judgment was properly granted upon the antitrust claims of all plaintiffs, it does appear that the issue may have been inadequately briefed.
Defendants assert that this cause of action was not sufficiently pled and that therefore
*1050
summary dismissal of it was appropriate. Business and Professions Code section 16756 provides that a cause of action is sufficiently pled if it states the “purpose or effects of the . . . combination, and that the accused is a member of . . . it, . . . without giving its name or description, or how, when or where it was created.” The complaint must contain “factual allegations of specific conduct” related to the cause of action.
(Jones
v.
H. F. Ahmanson & Co.
(1969)
Rausser’s complaint, in paragraph 86, includes an allegation of a section 16727 violation, and further alleges a purpose of preventing and substantially lessening competition in the wholesale distribution of Beck’s Beer in the relevant counties, thereby maintaining an artificially high resale price. Rausser contends that the complaint incorporates by reference the factual allegation that Rausser was terminated because it refused to cease handling Beck’s competitors. Paragraph 83 of the complaint does incorporate paragraph 77 which in turn incorporates exhibit F, the letter which discusses Beck’s reasons for terminating Rausser. However, paragraph 86, the only one that discusses section 16727, does not incorporate those factual allegations. (Since the complaint itself nowhere specifically alleges particular facts relating to an illegal exclusive dealing contract, it is possible that paragraph 86 contains a typographical error, and that § 16727 was intended to be 16726.)
Evidence Code section 1223 provides that: “Evidence of a statement offered against a party is not made inadmissible by the hearsay rule if: [H] (a) The statement was made by the declarant while participating in a conspiracy to commit a crime or civil wrong and in furtherance of the objective of that conspiracy; [t] (b) The statement was made prior to or during the time that the party was participating in that conspiracy; and [H] (c) The evidence is offered either after admission of evidence sufficient to sustain a finding of the facts specified in subdivisions (a) and (b) or, in the court’s discretion as to the order of proof, subject to the admission of such evidence.”
Restatement Second of Torts section 766, comment o, provides in pertinent part: “o. Causation. The question whether the actor’s conduct caused the third person to break his contract with the other raises an issue of fact. ...”
Although section 767 of the Restatement Second contains some changes in phrasing, the essence of the section and the applicable comment (now com. b) remains unchanged.
Although defendants maintain that causation is not present as Rausser was able to continue purchasing beer from Santa Clara Valley Distributors notwithstanding the letters from Woodlief, we believe that the question of damages is a factual one, as the letter may have contributed to the reduction of sources of supply for plaintiff Rausser.
Defendants state that a person, who in good faith, merely gives information or advice to other persons interested therein is not guilty of intentional interference with prospective business relations, citing Restatement Second of Torts, section 772. However, as noted by the court in Lowell, “[rjeliance on this theory is misplaced since, as pointed out in comment a to the Restatement of Torts section 772, one of the conditions of such justification is ‘[1] that the advice be requested . . (Id., at p. 20, fn. 1.) In the present case nothing in the allegations of the complaint or presented at summary judgment suggests that defendants were requested by the wholesalers to advise them concerning supplying plaintiff.
