Ordinarily, a temporary injunction will be granted pending trial on the merits (1) if there is probable cause for supposing that plaintiff will be able to sustain his primary equity, and. (2) if there is reasonable apprehension of irreparable loss unless injunc-tive relief be granted, or if in the court’s opinion it appears reasonably necessary to protect plaintiff’s rights until the controversy between him and defendant can be determined. Conference v. Creech and Teasley v. Creech and Miles, 256 N.C. 128, 123 S.E. 2d 619; 2 Strong, N. C. Index, Injunctions § 13 (Supp.).
Plaintiff’s affidavit makes out a prima facie showing of its right to the final injunctive relief sought. According to the uncontradicted evidence, plaintiff terminated defendant’s contract for cause. Defendant’s covenant not to compete after such a termination was (1) in writing, (2) entered into at the time and as a part of the original contract of employment, (3) based on a valuable consideration, (4) reasonable both as to the time and territory embraced in the restrictions, (5) fair to the parties, and (6) not against public policy. It, therefore, meets all the requirements for a valid restrictive covenant. Exterminating Co. v. Griffin and Exterminating Co. v. Jones, 258 N.C. 179, 128 S.E. 2d 139; Asheville Associates v. Miller and Asheville Associates v. Berman, 255 N.C. 400, 121 S.E. 2d 593. See *287Annot., Employee — Restrictive Covenant — Time, 41 A.L.R. 2d 15, 179 (1955). Considering the nature of plaintiff’s business, defendant’s agreement that, when his contract was terminated, he would not compete during the time the current telephone directory was in effect, plus a period of one year thereafter, is a reasonable time limitation. We may take judicial notice that (1) it is the custom of telephone companies annually to issue revised directories of their subscribers, and (2) an uninformed person desiring to rent a trailer would probably turn to the yellow pages index of the telephone directory to ascertain where one could be obtained. Stans-bury, N. C. Evidence §§ 11, 14 (2d Ed. 1963).
Defendant’s contention that plaintiff is not entitled to injunctive relief because the contract provision for liquidated damages provides an adequate remedy at law is untenable.
“ ‘The mere insertion in the contract of a clause describing the sum to be recovered for a breach as liquidated damages, but which were not intended to be payable in return for the privilege of doing the acts forbidden by the contract, will not exclude the equitable remedy and is regarded as put there for the purpose of settling the damages if there should be a suit and recovery for a breach.’ There may also be an action in the nature of a bill in equity, for what substantially would be a specific enforcement of the contract and restraining any further violation of it.” Cooperative Assn. v. Jones, 185 N.C. 265, 284, 117 S.E. 174, 183. Accord, Bradshaw v. Millikin, 173 N.C. 432, 92 S.E. 161. See 43 C.J.S., Injunctions § 80(6) (1945); 28 Am. Jur., Injunctions § 93 (1959).
On this record, .we think plaintiff was entitled to the temporary restraining order which Judge Bundy issued. ■ •
