In an action by plaintiff-respondent Mid-America Marketing Corporation for dam*420ages for the unauthorized disclosure and use of a trade secret in breach of confidence and implied contract, the jury found for respondent in the amount of $270,000, of which $20,000 represented an award of punitive damages. This is an appeal by defendants-appellants Dakota Industries, Inc. (Dakota) and LaMaur, Inc. (LaMaur) from that judgment. We reverse.
Respondent’s founder, Anthony Bachmeier (Bachmeier), has been associated with the beauty industry since 1959. In late 1974, Bachmeier and others struck upon an idea to improve the design and function of electrically heated bonnets used in the industry to facilitate the chemical processing of human hair. In December 1974, Bach-meier took an electrically heated cap manufactured by the TIZ Company to Dakota and discussed with them his ideas concerning improvements in the design of the cap. Bachmeier knew nothing of electrical design or theory and Dakota knew nothing of human hair processing or the theories thereof. Bachmeier indicated that the bonnet should be larger than the TIZ model and should fit snugly about the face in order to block out the outside air; that the material should be lightweight and feminine; that the temperature in the bonnet should be 180° (a figure arrived at by measuring the operating temperature of a hair processing device manufactured by Helene Curtis Co.); and that the heat should be uniformly distributed throughout the interi- or of the bonnet. Dakota suggested that a snowmobile suit hood manufactured by Dakota would be a good basis for the bonnet. Bachmeier agreed. At the conclusion of this initial meeting, Dakota committed itself to producing a working prototype of the bonnet. No non-disclosure agreement was signed by the parties; however, Bach-meier did inform Dakota that he did not want his idea “spread around town.”
Dakota then dismantled the TIZ cap to determine the method by which the heating circuitry had been produced. Following this examination, Dakota procured a heating pad, removed the heating elements (consisting of resistance wire, thermostat, control switch and power cord), and placed them intact into a snowmobile suit hood. The first prototype bonnet was delivered to Bachmeier on January 13, 1975, at which time he signed a receipt stating that the “design etc. [was] proprietary to Dakota Ind. subject to release for engineering development, funding.”
Subsequent prototypes produced by Dakota incorporating suggestions made by Bachmeier and others convinced Bachmeier that they were making progress toward a marketable product. Therefore, on February 18, 1975, respondent gave Dakota $10,-000 as advance payment toward 1,000 of the bonnets to be known as the ThermoChem Processing System. On February 21, 1975, Dakota and respondent entered into an agreement that provided that Dakota would produce the bonnets and would sell them only to respondent and that respondent would buy them only from Dakota. This agreement also acknowledged that Dakota had developed the ThermoChem Processing System with the advice of respondent. Dakota has never returned respondent’s $10,-000 nor has it delivered any bonnets to respondent. On March 19, 1975, respondent received by assignment from Bachmeier and others all interests held by them in the electrically heated bonnet. Respondent did not receive an assignment of any interest held by Dakota.
Beginning in February 1975, respondent began holding demonstrations of the Ther-moChem Processing System throughout South Dakota and Iowa. Prototypes were given to various beauty salon operators as a method of gaining experience in the actual operation of the device. No particular attempt was made to maintain secrecy. During the first week of March 1975, respondent’s employees attended a national beauty trade show in Chicago, Illinois. Respondent’s ThermoChem Processing System was on public display and demonstrations of its operation were given. Vic Born, Inc., a regional sales representative organization, was engaged by respondent to solicit orders for the ThermoChem Processing System; a prototype of the device was given to Born and was never returned. In conjunction *421with the Chicago show, respondent prepared brochures and purchased advertising which pictured the ThermoChem Processing System. These pictures and accompanying text disclosed all of the unique features of the ThermoChem Processing System (its size, feminine appearance, close fit about the face, purpose, ability to retain moisture and maintain constant, even heat) except the details of its electrical circuitry and construction, about which respondent had no knowledge.
At the Chicago show, respondent made its first contact with LaMaur. As a result of LaMaur’s interest in the ThermoChem Processing System, respondent withdrew the prototypes from public display. On March 2, 1975, LaMaur signed a memo indicating interest in acquiring exclusive rights to distribution of the ThermoChem Processing System. (This memo does not indicate from whom these rights were to be acquired. It was/ however, signed by Bach-meier and another of respondent’s stockholders but not as agents of respondent.) LaMaur invited Bachmeier to demonstrate the ThermoChem Processing System at another beauty industry show in New York City in mid-March 1975; simultaneously, respondent displayed the ThermoChem Processing System at still another show in Iowa.
Negotiations between respondent and LaMaur did not lead to a contract. Following this breakdown, LaMaur began negotiations with the KAZ Company to produce a hair processing bonnet that would incorporate the ideas openly disclosed by respondent — namely, full head coverage with heat and moisture control. Neither KAZ nor LaMaur, nor for that matter respondent, possessed the technical expertise developed by Dakota to actually construct an appropriate bonnet. Therefore, KAZ had to start at the beginning with original engineering. When Dakota approached LaMaur, as discussed infra, LaMaur realized that a marketable product could be procured from Dakota much sooner than from KAZ; hence, the contract with KAZ was terminated.
Respondent meanwhile decided to undertake national distribution of the Thermo-Chem Processing System through its own network of sales representatives. Several of these representatives handled LaMaur’s beauty product line and there was evidence that respondent became aware of these representatives through its negotiations with LaMaur. To establish this distribution network, respondent on May 2, 1975, entered into a contract with Dakota whereby Dakota agreed, among other things, to sell Ther-moChem Processing Systems only to respondent and respondent agreed to produce orders for 12,500 ThermoChem Processing System units each calendar quarter. Dakota’s project manager testified that by calendar quarters they meant each ninety days beginning May 2, 1975. Respondent produced no testimony to challenge this understanding. Respondent did not possess sufficient financial resources to underwrite the credit of cosmotologists ordering the bonnets; therefore, Dakota agreed to underwrite that risk for those customers Dakota found to be credit worthy and that only those orders would count against the 12,500 units respondent was required to sell each quarter in order to avoid default on the contract.
Pursuant to this contract, from May to July of 1975 respondent submitted orders to Dakota for 3,632 units. Of these, only 930 were deemed to be credit worthy by Dakota; however, none of these orders were filled.
On May 23, 1975, respondent and Dakota met and decided that Dakota should attempt to reestablish the negotiations with LaMaur. Respondent attempted to place the following restrictions upon Dakota’s negotiation with LaMaur: no agreement was to be reached during the initial meeting; LaMaur was not to be granted exclusive distribution rights; respondent was to be relieved of any obligations to sales representatives; price of the units was not to be discussed; and technical aspects of the ThermoChem Processing System were not to be revealed. The record reveals an unsupported statement by Bachmeier that Dakota agreed to these restrictions. On May *42227, 1975, Dakota and LaMaur met and conferred. An agreement in principle was reached at this meeting. On May 29, 1975, Dakota submitted a proposed agreement to LaMaur and turned over to LaMaur the orders for ThermoChem Processing Systems that respondent had placed with Dakota. LaMaur submitted a counter-offer on June 13, 1975; this offer called for respondent’s consent to the agreement but did not make respondent a party to the contract and made no provision for respondent’s compensation.
On June 20, 1975, Dakota submitted a contract to respondent intended to supplant the May 2 agreement. Under this proposal respondent would receive 18% of all revenues on sales of bonnets made by Dakota and sold to LaMaur. This offer also required respondent to consent to the June 13 contract between Dakota and LaMaur. Along with this new contract, Dakota provided respondent a copy of Appendix A to the contract between appellants, which purports “[t]o identify the proprietary aspect of the Electric Bonnet Processing System, Dakota Industries Inc. Part No. 57822.” The document also describes all the materials and assembly steps required to produce a bonnet. There is no discussion of how the system works or how it should be used in the processing of human hair. Respondent rejected this offer.
Dakota submitted “Appendix A” to La-Maur on June 20,1975, and LaMaur committed itself, through issuance of an internal “merchandising decision" memorandum, to sell the bonnet. Respondent submitted counter-offers to Dakota on July 2 and 9, 1975, both of which were rejected because they would have allowed respondent to produce processing systems in competition with the ThermoChem Processing System.
On July 25, 1975, appellants entered into a written agreement for Dakota’s manufacture and LaMaur’s sale of the bonnet. A two-party contract, it made no provision for respondent. Dakota justified its course of action as necessary to protect its substantial investment because of the intractable stance respondent had assumed in negotiations, because Dakota knew that LaMaur was going forward with a bonnet and would if necessary purchase one from a competitor, and because it believed the May 2 contract to have been breached through respondent’s inability to sell 12,500 units during the first ninety days. During July and August 1975, Dakota sold 18,939 units to LaMaur. LaMaur’s sales dropped dramatically after the first month, however- — ■ in fact returns exceeded sales — and LaMaur wound up with net sales for the first year of only 12,707 bonnets. Neither Dakota nor LaMaur has ever paid anything to respondent as compensation for its interest in the bonnet. No bonnets have ever been delivered to respondent nor has Dakota returned respondent’s $10,000 advance payment.
The Restatement of Torts § 757 (1939) provides:
One who discloses or uses another’s trade secret, without a privilege to do so, is liable to the other if
(a) he discovered the secret by improper means, or
(b) his disclosure or use constitutes a breach of confidence reposed in him by the other in disclosing the secret to him, or
(c) he learned the secret from a third person with notice of the facts that it was a secret and that the third person discovered it by improper means or that the third person’s disclosure of it was otherwise a breach of his duty to the other, or
(d) he learned the secret with notice of the facts that it was a secret and that its disclosure was made to him by mistake.
It is apparent that respondent must prove that it indeed had a trade secret in order for liability to attach under this theory.
Trade secrets have been found in a wide variety of subjects, including but not limited to: chemical formulas, Platinum Products Corp. v. Berthold, 280 N.Y. 752, 21 N.E.2d 520 (1939); industrial processes, Sun Dial Corp. v. Rideout, 29 N.J.Super. 361, 102 A.2d 90 (1954), aff’d 16 N.J. 252, 108 A.2d *423442 (1954); pricing information, Simmons Hardware Co. v. Waibel, 1 S.D. 488, 47 N.W. 814 (1891); customer lists, Town and Country House & Homes Serv., Inc. v. Evans, 150 Conn. 314, 189 A.2d 390 (1963); and sources of supply, Water Services, Inc. v. Tesco Chemicals, Inc., 410 F.2d 163 (5th Cir. 1969). See generally E. Kintner, An Intellectual Property Law Primer (1975). The numerous situations in which trade secrets might arise militates against a set definition of a trade secret.1 Restatement of Torts § 757, comment b (1939), however, provides a widely relied upon definition of a trade secret. See Kewanee Oil Co. v. Bicron Corp., 416 U.S. 470, 94 S.Ct. 1879, 40 L.Ed.2d 315 (1974). The comment states:
A trade secret may consist of any formula, pattern, device or compilation of information which is used in one’s business, and which gives him an opportunity to obtain an advantage over competitors who do not know or use it. It may be a formula for a chemical compound, a process of manufacturing, treating or preserving materials, a pattern for a machine or other device, or a list of customers. It differs from other secret information in a business (see § 759) in that it is not simply information as to single or ephemeral events in the conduct of the business, as, for example, the amount or other terms of a secret bid for a contract or the salary of certain employees, or the security investments made or contemplated, or the date fixed for the announcement of a new policy or for bringing out a new model or the like. A trade secret is a process or device for continuous use in the operation of the business. Generally it relates to the production of goods, as, for example, a machine or formula for the production of an article. It may, however, relate to the sale of goods or to other operations in the business, such as a code for determining discounts, rebates or other concessions in a price list or cata-logue, or a list of specialized customers, or a method of bookkeeping or other office management.
Secrecy. The subject matter of a trade secret must be secret. Matters of public knowledge or of general knowledge in an industry cannot be appropriated by one as his secret. Matters which are completely disclosed by the goods which one markets cannot be his secret. Substantially, a trade secret is known only in the particular business in which it is used. It is not requisite that only the proprietor of the business know it. He may, without losing his protection, communicate it to employees involved in its use. He may likewise communicate it to others pledged to secrecy. Others may also know of it independently, as, for example, when they have discovered the process or formula by independent invention and are keeping it secret. Nevertheless, a substantial element of secrecy must exist, so that, except by the use of improper means, there would be difficulty in acquiring the information. An exact definition of a trade secret is hot possible. Some factors to .be considered in determining whether given information is one’s trade secret are: (1) the extent to which the information is known outside of his business; (2) the extent to which it is known by employees and others involved in his business; (3) the extent of measures taken by him to guard the secrecy of the information; (4) the value of the information to him and to his competitors; (5) the amount of effort or money expended by him in developing the information; (6) the ease or difficulty with which the information could be properly acquired or duplicated by others.
Restatement of Torts § 757 at 5-6 (1939). These guidelines emphasize processes that are used in a business to produce products. It is the knowledge of these processes that gives the holder of that knowledge a competitive advantage over those without that knowledge.
Respondent through Bachmeier had knowledge of a process that would give *424superior results in the .treatment of human hair. This process dealt with controlling the heat and moisture for a specified time with specified chemicals when giving beauty treatments. Respondent tacitly acknowledged the nature of its trade secret in paragraph VI of its complaint. “That in late 1974, Plaintiff confidentially contacted Dakota and disclosed to Dakota its trade secret, namely the invention, use and application of the System.” It cannot seriously be argued that respondent invented the electrically heated cap to be used in the treatment of human hair inasmuch as Bach-meier brought an existing model to his first meeting with Dakota.
Dakota developed knowledge of a process that would produce an electrically heated bonnet. This knowledge was contained in “Appendix A” and dealt with fabric and insulation weights, stitch sizes, pattern shapes, electrical diagrams, etc. This knowledge gave Dakota a clear advantage over its competitors, for when LaMaur learned that this knowledge could be used in its behalf through employing Dakota, it terminated the KAZ Company’s effort to produce a similar bonnet. Dakota took steps to protect the secrecy of this process, for whep respondent intended to deliver three bonnets to LaMaur for testing, Dakota instructed respondent to inform LaMaur that the bonnets were not to be disassembled and were to be used for temperature testing only. Respondent took no steps to protect its knowledge of how the bonnet was to be used but instead freely disclosed this knowledge to others, including LaMaur.
In this case it is clear that the bonnet is not the secret; the secret relates to the production of the bonnet in the case of Dakota and the use of the bonnet in the case of respondent. This is not to say that a product can never be a secret. For example, in K & G Oil Tool & Service Co. v. G & G Fishing Tool Serv., 158 Tex. 594, 314 S.W.2d 782 (1958), plaintiff produced a magnetic tool for fishing broken bits out of oil wells. Plaintiff leased these tools to defendant under an agreement which provided that defendant would not disassemble the tool and thereby learn how it was made. Plaintiff recovered damages and was granted an injunction after a jury determination that defendant could not have produced the highly similar tool it began to manufacture without disassembling plaintiff’s tool.2
There is no evidence in the present record from which the jury could find that the appellants singly or in concert wrongfully appropriated respondent’s trade secret. Appellants’ motion for a directed verdict on respondent’s first cause of action should have been granted.
Respondent’s second cause of action alleged a breach of an implied contract. Respondent’s theory on this cause of action was that because Dakota and LaMaur knew that respondent had an interest in the bonnet when they met, they were under an obligation to provide for respondent’s interest. At the conclusion of respondent’s case, appellants moved for a directed verdict on the second cause of action, arguing that the May 2, 1975, contract between respondent and Dakota included within its terms the transaction complained of by respondent and therefore the theory of implied contract would not lie. Appendix B, paragraph three of that contract provides:
*425In the event this agreement is terminated by either party for any reason and Dakota continues to produce and market the processing system or Mid America continues to produce, have produced, or market any similar systems (as qualified by paragraphs 10.0 through 10.3) the mutual parties hereby agree to pay commissions respectively to each other on a schedule consisting of five percent (5%) of the first two-hundred-fifty-thousand dollars; of three percent (3%) of the next four-hundred-thousand dollars and of two percent (2%) of all remainder for as long as either party manufacturers [sic], markets, or sells this product.3
Respondent argues that this paragraph became inoperative when a third party — La-Maur — became involved. We do not find this argument persuasive. For the provision to have any meaning at all, the parties must have contemplated the possibility that Dakota would market the processing system to a third party. As this court stated in Werre v. Northwest Thresher Co., 27 S.D. 486, 490, 131 N.W. 721, 722 (1911):
There is no question but what, where there is a valid express contract existing between parties in relation to a transaction fully fixing the rights of each, there is no room for an implied promise, or suit on quantum meruit. Ball v. Dolan, 21 S.D. 619, 114 N.W. 998, 15 L.R.A. (N.S.) 272. Under such circumstances the suit upon such transaction must be based on the contract alone .
See also Thurston v. Cedric Sanders Co., 80 S.D. 426, 125 N.W.2d 496 (1963).
When “parties stipulate in a contract what the consequences of a breach of the agreement shall be, such stipulation if reasonable is controlling and excludes other consequences.” 17 Am.Jur.2d Contracts § 522 at 1009 (1964). Or, as stated by the Supreme Court of Washington in United Glass Workers’ Local No. 188 v. Seitz, 65 Wash.2d 640, 642, 399 P.2d 74, 75 (1965):
This court is committed to the view that, when parties to a contract foresee a condition which may develop and provide in their contract a remedy for the happening of that condition, the presumption is that the parties intended the prescribed remedy as the sole remedy for the condition, and this presumption is controlling where there is nothing in the contract itself or in the conditions surrounding its execution that necessitates a different conclusion.
The record provides no evidence from which the jury could determine that the May 2, 1975, contract between respondent and Dakota was not a valid, enforceable expression of the intent of the parties. It was error to refuse to direct a verdict on respondent’s second cause of action.
The judgment is reversed, and the case is remanded to the circuit court for entry of judgment dismissing respondent’s complaint.

. From the facts presented in this case, it is doubtful that any of the parties could successfully establish the existence of a trade secret in the bonnet. As noted by Professor Alexander in his work on commercial torts:
[F]or a combination of features to be protected as a secret, it must be more than a mere aggregation of well known parts, even if the parts had not previously been assembled in the manner in which the “secret” combination has been put together.
G. Alexander, Commercial Torts § 3.2 at 209 (1973). Here, respondent took an existing electrically heated bonnet to Dakota and told Dakota the temperature it wanted based on another hair-processing system; the chemical treatment and protective liner came from other sources; Dakota took an existing snowmobile hood, heating elements from a heating pad, and temperature controls from a third manufacturer to create the prototype bonnet. These facts militate against a finding of a protectible trade secret in the bonnet. See also Nickelson v. General Motors Corporation, 361 F.2d 196 (7th Cir. 1966).
. We note that the United States Supreme Court has recently upheld the validity of contracts that grant rights beyond the protection available under federal patent law. Aronson v. Quick Point Pencil Co., 440 U.S. 257, 99 S.Ct. 1096, 59 L.Ed.2d 296 (1979).
