Defendant, W. E. Rowe, appeals from a decree enjoining him “from artificially inseminating cattle, either directly or indirectly, in McDonald County, Missouri for a period of two years from November 21, 1957.” About May 1948, Rowe (who theretofore had been a dairy farmer in McDonald County for fifteen years) began to work as an artificial inseminator of cattle — a calling frequently identified by the less discriminating and descriptive, but more dignified and distinguished, title of “technician.” For a time, Rowe “worked on a commission” for Harry Rollins, a “pioneer of the artificial insemination business in Southwest Missouri,” who did business as the Dairy Breeding Association of Carthage, Missouri. When Rollins sold his bulls in November 1951, to J. R. Prentice of Chicago, who does business as American Breeders Service (hereinafter referred to as ABS), Rowe entered the employ of ABS under a written “Technician’s Employment Contract” which clearly and plainly established an employer-employee relationship between ABS and Rowe and spelled out the rights and obligations of the respective parties. Rowe’s employment was to “inseminate all cows presented for service” in the stipulated “service area” of McDonald County, Missouri, “with semen furnished and at fees established by the employer.”
Rowe continued in the employ of ABS until May 1, 1957, under similar written contracts. Each such contract provided that: “The Technician (Rowe) shall spend his full time on the Employer’s (ABS) business. Such time as he has free after inseminating cows and performing other duties required hereunder, he shall spend in promoting the Employer’s business and soliciting new business.” And, each such contract contained a restrictive covenant in substantially the following language quoted from paragraph 9 of the last “Technician’s Employment Contract” dated January 11, 1955 (hereinafter referred to as the employment contract) : “While employed under this contract, and any extension or renewal thereof, and as long as the Employer carries on the business of artificial insemination of cattle during the two years after the termination of such employment, the Technician shall not * * *, in the service area (McDonald County, Missouri), artificially inseminate or take or solicit orders for the artificial insemination of cattle, with semen other than such as shall be furnished to the Technician by or through or with the permission of the Employer.”
In May 1957, ABS sold to Don L. Hoyt of Springdale, Arkansas, “all right, title and interest of ABS in and to ABS’s retail artificial inseminating business” in seven Missouri counties, including McDonald County, and Hoyt became the “distributor” for ABS semen in those counties. Under date of May 1, 1957, Hoyt (d/b/a Ozark Proved Sire Service) as “distributor” and Rowe as “purchaser” entered into a written “Contract for the Sale of Fresh Semen” (hereinafter referred to as the fresh semen sales contract). In this contract, the parties agreed, among other things, “that the purchaser (Rowe) is an independent contractor and the distributor (Hoyt) shall not direct, guide and supervise the manner in which the purchaser .does his work” and “that the purchaser has no vested property right under this contract, but only a franchise to sell American Breeders Service semen in the above described territory (McDonald County, Missouri) for so long as this contract is in effect.” The fresh semen sales contract contained two restrictive covenants. The first was that “the purchaser (Rowe) during the term of this contract, and for a period of two years after the termination of such agreement shall not (either on his own account or of a partner, representative, or otherwise) inseminate cows with semen, either fresh or frozen, other than that furnished by distributor (Hoyt),” and that “after the termination *460of this agreement, purchaser shall not have the right to inseminate any cows serviced under this contract.” The second was contained in another paragraph which embodied in the fresh semen sales contract by reference the restrictive covenant hereinbe-fore quoted from paragraph 9 of the employment contract of January 11, 1955. The fresh semen sales contract was “approved” in writing by ABS, although ABS was not a party thereto. ; . ■. • •
On October 8, 1957, Rowe signed a written “Resignation” in which he tendered “my resignation of employment, either as servant or independent contractor, to the American Breeders Service and the Ozark Proved Sire Service Co.,” effective “30 days from date.” The testimony concerning execution of this “Resignation” was in sharp and irreconcilable conflict. Hoyt and Divine (a field representative of ABS) testified that Rowe was “very bitter” toward ABS and “wanted to resign,” and that he had signed the “Resignation” notwithstanding the fact that they had “begged Mr. Rowe * * * an hour or so not to resign.” On the other hand, Rowe said that he did not read the “Resignation,” and that he signed it because Hoyt and Divine requested and, in fact, “forced” him to do so, although (at another point in his testimony) Rowe conceded that Hoyt and Divine had “encouraged” him to continue “under the terms of the contract.” In any event, the “Resignation” appears to have been an outgrowth of what Rowe referred to as “some difficulty” and “some disagreements,” wholly unexplained in the record except for the suggestion inherent in Rowe’s statement that his objection to continuing the sale of ABS semen was that ABS wanted to raise the breeding fee from $6 to $7.
On October 16, 1957, Ozark Proved Sire Service Company of Springdale (an Arkansas corporation controlled by Hoyt) as distributor and Rowe as purchaser executed another “Contract for the Purchase and Sale of American Breeders Service Proved Sire Semen” which was to have become effective “at day of delivery of frozen semen.” This contract (hereinafter referred to as the frozen semen sales contract) provided, as had the fresh semen sales contract of May 1, 1957, that “the purchaser is an independent contractor” and that he had “only a franchise to sell American Breeders Service semen” in McDonald County. Notwithstanding the fact that the frozen semen sales contract by its plain terms never became effective because no frozen semen was delivered to Rowe (although all interested parties apparently contemplated as early as May 1957, that a change from fresh to frozen semen would be made when the latter became available), Hoyt, as President of Ozark Proved Sire Service Company, gave to Rowe on October 21, 1957, formal written “Notice of Termination of Contract” in which it was stated that “pursuant to franchise contract dated Oct. 16, 1957 * * * 30 days notice is hereby given * * * that aforesaid contract shall be cancelled and set aside, and that any employment status, contractural (sic) or otherwise, shall be cancelled and held for naught as between the parties hereto.” (All emphasis herein is ours.) And, notwithstanding the foregoing notice of October 21, 1957, and the fact that the frozen semen sales contract was the only contract bearing the date of October 16, 1957, Hoyt wrote Rowe on November 18, 1957, that “the termination of a certain contract for sale of fresh semen dated October 16, 1957, does not in any way effect (sic) our contractural (sic) relationship of another contract for sale of frozen semen dated October 16, 1957.” And, notwithstanding Rowe’s “Resignation” which was “accepted” by Hoyt on October 8, 1957 (when the fresh semen sales contract of May 1, 1957, was the only contract between Hoyt and Rowe), Rowe continued to purchase fresh ABS semen from Hoyt until November 20, 1957, and Hoyt continued to ship to Rowe for five or six days after that date until it became apparent that Rowe was not using the ABS semen sent to him.
Proceeding on the premise that he “got fired” by ABS or Hoyt and “had to make *461a living,” Rowe entered into a “Dealer’s Contract” with Eastern Iowa Breeders on November 21, 1957; and, in the brief span of eighteen days before a temporary injunction was granted in this case on December 9, 1957, Rowe serviced with Eastern Iowa semen one hundred cows in McDonald County, many of whom previously had been serviced by him with ABS semen. The undisputed testimony in this case was that, within a few days after November 20, 1957, Hoyt’s individual distributorship for ABS semen was terminated, and ABS “took over” McDonald County and employed as a technician therein one Gresham who was still working as an employee of ABS in McDonald County at the time of trial.
Plaintiffs, ABS and Hoyt, predicate their alleged right to injunctive relief upon defendant Rowe’s violation of the restrictive covenants in the fresh semen sales contract of May 1, 1957. Although we have seined the seas of authority without netting any such curious concatenation of contracts, covenants, conflicts and confusion as that washed ashore in this case, certainly there is no dearth of legal literature dealing with restrictive covenants, as is emphasized and demonstrated in Arthur Murray Dance Studios of Cleveland v. Witter, Ohio Com.Pl., 105 N.E.2d 685 — a studious and scholarly exposition sharply contrasting with the frequently shallow and superficial, sometimes slipshod and slovenly, treatment accorded important questions by counsel and courts alike. Stated in general terms, the law now is that a covenant restraining an employee, upon termination of employment, from competing with his former employer is valid and enforceable if it is reasonable as to the employer, the employee and the public, when viewed in the light of all of the facts and circumstances of the particular case under consideration. See the multitude of authorities collected and classified in the Arthur Murray case, supra, 105 N.E.2d loc. cit. 691-693. To be reasonable, the restraint usually must be qualified as to both time and area and must be no greater than fairly required for protection of the person for whose benefit it is imposed. Renwood Food Products v. Schaefer, 240 Mo.App. 939, 951, 223 S.W.2d 144, 151.
By the fresh semen sales contract of May 1, 1957, Hoyt, a distributor, granted to Rowe, an independent contractor, “only a franchise to sell American Breeders Service semen” in McDonald County, but the first restrictive covenant in that contract, although limited as to time (i. e., two years after termination of the contract), purported to prohibit Rowe from any artificial insemination of cattle (except with ABS semen furnished by Hoyt) without limitation as to area. Compare Mallinck-rodt Chemical Works v. Nemnich, 83 Mo.App. 6, 15-16, affirmed 169 Mo. 388, 69 S.W. 355. A restrictive covenant limiting an individual in the exercise or pursuit of his occupation is in restraint of trade [Corbin on Contracts, Vol. 6, § 1392, loc. cit. 509; Restatement of Contracts, Vol. 2, § 513, p. 987], and the burden of establishing its validity, by showing that it is reasonable, rests upon the party claiming its benefit. Arthur Murray case, supra, 105 N.E.2d loc. cit. 693(6) and authorities there collected; Grace v. Orkin Exterminating Co., Tex.Civ.App., 255 S.W.2d 279, 283(2); Kadis v. Britt, 224 N.C. 154, 29 S.E.2d 543, 545(2), 152 A.L.R. 405. With no evidence in the record before us as to the area within which ABS semen has been or is sold, and with an affirmative showing that, after termination of his individual distributorship during the latter part of November, 1957, Hoyt had no employee, dealer or “purchaser” in McDonald County, we cannot find that the restraint imposed by the first restrictive covenant, wholly unlimited as to area, was reasonable and no greater than fairly required for protection of ABS and Hoyt, who here seek its shelter. Compare Delmar Studios of the Carolinas v. Kinsey, 233 S.C. 313, 104 S.E.2d 338. Accordingly, we hold that the first restrictive covenant was invalid.
*462However, the second restrictive covenant (as embodied in the fresh semen sales contract of May 1, 1957, by reference to paragraph 9 of the employment contract of January 11, 1955) maintained in full force and effect the restriction that, while Rowe was employed by ABS and “as long as (ABS) carries on the business of artificial insemination of cattle during the two years after the termination of such employment,” Rowe would not inseminate cattle (except with semen furnished by, through or with the permission of ABS) “in the service area” which was specifically described as, and limited to, McDonald County. Thus, the restraint imposed by the second restrictive covenant was qualified, and we think reasonably so, both as to time and as to area. Haysler v. Butterfield, 240 Mo.App. 733, 218 S.W.2d 129; Northeast Georgia Artificial Breeders Ass’n v. Brown, 209 Ga. 547, 74 S.E.2d 660; annotation 43 A.L.R.2d 94; annotation 41 A.L.R.2d 15. It is true that, as Rowe emphasizes, neither ABS nor Hoyt imparted any trade secrets to him or gave him any list of customers. However, an employer may be entitled also to invoke the protection afforded by a reasonable restrictive covenant against attempts by a former employee to solicit and entice away customers whom he had served for such employer. Renwood Food Products v. Schaefer, supra, 240 Mo.App. loc. cit. 952, 223 S.W.2d loc. cit. 151.
It does not lie in Rowe’s mouth to say that injunctive relief should be denied to ABS, his former employer, on the theory that the owners of cattle inseminated by Rowe during the period of his employment by ABS were customers of Rowe, and not of ABS. When Harry Rollins, for whom Rowe had “worked on a commission,” sold his bulls to ABS in November 1951, Rowe became a full-time employee of ABS, with whom he specifically covenanted in writing that “such time as he (Rowe) has free after inseminating cows and performing other duties required hereunder, he shall spend in promoting the Employer’s business and soliciting new business” — the same obligation any loyal employee would have owed to a new employer [Haysler v. Butterfield, supra, 240 Mo.App. loc. cit. 739, 218 S.W.2d loc. cit. 131]; and, a map of McDonald County (received in evidence), showing the location of ABS’ customers served in 1956 and of sixty-six new customers “who started” in 1957, indicates that Rowe in good faith recognized his obligation to promote, and in fact did promote, the sale and use of ABS semen in McDonald County. Certainly, ABS had a right to safeguard and protect, by a reasonable restrictive covenant, the business and good will developed in McDonald County as the fruit of Rowe’s employment by ABS for the period of more than five and one-half years from November 1951 to May 1957. City Ice & Fuel Co. v. Snell, Mo.App., 57 S.W.2d 440; Willis v. Dictograph Sales Corp., 222 Ind. 523, 54 N.E.2d 774. See also Masden v. Travelers’ Ins. Co., 8 Cir., 52 F.2d 75, 77, 79 A.L.R. 469; Chicago Life Ins. Co. v. Tiernan, 8 Cir., 263 F. 325, 332.
The record plainly shows that, in the period of eighteen days after November 20, 1957, Rowe serviced one hundred cows in McDonald County with semen purchased from Eastern Iowa Breeders, a competitor of ABS, many of those cows having been serviced by him previously with ABS semen; and, the evidence is just as clear that, although Rowe had serviced with ABS semen one hundred twenty cows in McDonald County during August 1957, one hundred seven cows during September 1957, and eighty-one cows during the period from November 1 to 20, 1957, sales of ABS semen in McDonald County immediately dropped to an insignificant level when Rowe ceased its use, Gresham (the full-time technician-employee for McDonald County hired by ABS shortly after November 20, 1957) having bred only seven cows during the entire month of December 1957. So, although there is no suggestion that the cows in McDonald County recognized any distinction between Rowe and Gresham or indicat*463ed any preference for either, the owners of the cows apparently did. “Human nature being what it is” [Haysler v. Butterfield, supra, 240 Mo.App. loc. cit. 739, 218 S.W.2d loc. cit. 131], ABS sought, by the restrictive covenant in paragraph 9 of the employment contract which was carried forward and maintained as the second restrictive covenant in the fresh semen sales contract, to guard against just such consequences as followed Rowe’s termination of use of ABS semen; and, in the light of all of the facts and circumstances of the instant case, we are constrained to conclude that the restraint imposed by this restrictive covenant was reasonable as to Rowe and no greater than fairly required for protection Of ABS [cf. Ontario. County Artificial Breeders Coop. v. Shappee, 205 Misc. 175, 127 N.Y.S.2d 888; Northeast Georgia Artificial Breeders Ass’n v. Brown, supra], and that “(t)here is no practical man who would not smile at the conceit that the public welfare would sustain an injury by enforcing” it. Presbury v. Fisher & Bennett, 18 Mo. 50, 51; Gordon v. Mansfield, 84 Mo.App. 367, 377; Mitchell v. Branham, 104 Mo.App. 480, 486, 79 S.W. 739, 740.
But, since the restrictive covenant under consideration is one in restraint of trade and personal liberty, it should not be construed to extend beyond its fair import. State ex rel. Youngman v. Calhoun, Mo.App., 231 S.W. 647, 649; Athletic Tea Co. v. Cole, Mo.App., 16 S.W.2d 735, 736 (2). The restraint imposed upon Rowe by this covenant was for the period of his employment by ABS “and as long as the'Employer (ABS) carries on the business of artificial insemination of cattle during the two years after the termination of such employment!’ There can be no doubt but that Rowe’s employment by ABS terminated on May 1, 1957, when he became an independent contractor under the fresh semen sales contract between Hoyt and Rowe. Accordingly, the period of two years for and during which ABS is entitled to injunctive enforcement of this covenant expired on April 30, 1959.
We need not and do not determine whether, under other circumstances, Hoyt might have been entitled to enforce the second restrictive covenant in the fresh semen sales contract, for the record establishes beyond room for argument that Hoyt’s individual distributorship for ABS semen was terminated within a few days after November 20, 1957, and that thereafter Hoyt had no employee, dealer or “purchaser” in McDonald County and acted only in a supervisory capacity for ABS. In short, there is no evidence that Hoyt had any business interest in McDonald County either when this action was instituted or when it was tried. The remedy of injunction, frequently characterized as “the strong arm of equity,” is a summary, transcendent and extraordinary remedy, may not be invoked as a matter of course, and should be exercised sparingly and only in clear cases [Barnhart v. Ripka, Mo.App., 297 S.W.2d 787, 792(10), and cases there collected; 28 Am.Jur., Injunctions, § 24, p. 217]; and, with no showing of actual or threatened injury to Hoyt, he was entitled to no in-junctive relief. 28 Am.Jur., Injunctions, § 108, loc. cit. 302; Corbin on Contracts, Vol. 6, § 1394, loc. cit. 520, 522. Consult also 43 C.J.S., Injunctions, § 22, p. 439; Ibid., § 23, p. 446; Ibid., § 84b(l), loe. cit. 567; 28 Am.Jur., Injunctions, § 47, p. 242; Ibid., § 83, p. 277. And, see again the Arthur Murray case, supra, 105 N.E.2d loc. cit. 701 et seq.
The decree of the trial court is set aside and the cause is remanded with directions to enter a decree (1) finding the issues in favor of ABS and against Rowe and enjoining him from artificially inseminating any cattle, or taking or soliciting orders therefor, in McDonald County, Missouri, prior to May 1, 1959, (2) dismissing the bill in equity with prejudice as to plaintiff Hoyt, and (3) taxing the costs in the trial court against plaintiff Hoyt and defendant Rowe, share and share alike, i. e., one-half of such costs to be paid by Hoyt and one-half to be paid by Rowe. Costs upon this *464appeal are taxed against respondents ABS and Hoyt, share and share alike.
