KAUGER, Justice.
On June 14, 1989, we granted certiorari to consider a question of first impression: whether a court may modify an otherwise void covenant not to compete so that the covenant constitutes a reasonable restraint on trade falling outside the forbidden parameters of 15 O.S.1981 § 217. Section 217 provides:
“Every contract by which any one is restrained from exercising a lawful profession, trade or business of any kind, otherwise than as provided by the next two sections, is to that extent void.”
We find that covenants not to compete cannot be modified judicially to conform with the reasonable restrictions of § 217 if essential elements of a contract must be supplied.
FACTS
In 1977, the appellee, Daniel D. Pickard (Pickard), was employed by Harlan Agents and Brokers, Inc., an affiliate of Harlan Holding Company (Harlan), an insurance company in which Pickard owned stock. Bayly, Martin & Fay Services, Inc. (BMF Services), an affiliate of the appellant, Bayly, Martin & Fay, Inc. (Bayly), purchased Harlan.
On December 5, 1977, Pickard sold his Harlan Stock to BMF Services and entered into a covenant not to compete. Two days later, Pickard executed an employment agreement with Harlan. This latter agreement restricted Pickard from dealing with any of Harlan’s customers for three years after termination. It also denied Pickard access to any parties who became Harlan clients during his employment or to prospective clients contacted before his termination.
After BMF Services purchased Harlan, Bayly became Pickard’s employer and the assignee of the covenant not to compete and the employment agreement. On November 15, 1984, Pickard executed a buy-sell agreement which contained a nonsolici-tation of company business provision. This covenant was executed pursuant to Pick-ard’s purchase of stock in BMF Services. Bayly fired Pickard on December 11, 1986; and Pickard sold his stock back to the company. Of the three agreements, only the covenant not to compete is limited geographically. It is operative in three states: Oklahoma, Texas, and Colorado.
On February 9, 1987, Bayly filed a petition in the district court alleging that Pick-ard had violated the terms of the employment and buy-sell agreements by accepting insurance business from Bayly’s customers. Bayly sought injunctive relief to enjoin Pickard from violating the two agreements. The trial court issued a temporary restraining order on February 9, 1987; and it ordered a hearing on the application for temporary injunction for February 27, [1170]*11701987. On February 18, 1987, Pickard filed a motion to vacate the restraining order. Five days later, he filed a motion for a protective order staying discovery until the trial court ruled on the legality of the agreements. Except for allowing Pickard’s deposition to be taken, the trial court prohibited any discovery.
Pickard also filed an oral motion for summary judgment. His brief in support of the motion was filed on March 3, 1987. The trial court heard argument on the motion for summary judgment on March 13, 1987. On March 17, 1987, the trial court sustained Pickard’s motion for summary judgment finding that the restrictive covenants were so broad, so comprehensive, so pervasive, and so contrary to public policy that they were void as a matter of law. On appeal, the Court of Appeals also found that the restrictive covenants were an overly broad restraint under 15 O.S.1981 § 217. However, the Court of Appeals reformed the agreements to restrict the geographical area of competition to Tulsa County and remanded with instructions.
TITLE 15 O.S.1981 § 217 ALLOWS REASONABLE RESTRICTIONS ON THE EXERCISE OF A LAWFUL PROFESSION, TRADE, OR BUSINESS; HOWEVER, THE CONTRACT MAY NOT BE JUDICIALLY MODIFIED IF ESSENTIAL ELEMENTS OF THE CONTRACT MUST BE PROVIDED TO BRING IT WITHIN THE RULE OF REASON.
Pickard asserts that the Court of Appeals erred in modifying the restrictive covenants because they are void pursuant to § 217. Although Bayly does not disagree with the Court of Appeals’ determination that the restrictive covenants are an overly broad restraint under § 217, it argues that the Court of Appeals’ modification of the agreements which restricted their operative effect to Tulsa County rendered their provisions reasonable and, therefore, enforceable.
Contracts in restraint of trade are void and unenforceable unless they fall within one of the two statutorily created exceptions to the general rule — sale of good will or dissolution of a partnership.1 Although Bayly alleged that the good-will exception found in § 218 was applicable before both the trial court and the Court of Appeals, it’s applicability is not argued by either of the parties on certiorari.2 Even if the applicability of § 218 had been asserted, the miniscule amount of stock — .8%— sold back to BMF Services by Pickard is insufficient to support an argument that the goodwill exception to § 217 is applicable.3
A
REASONABLE RESTRICTIONS ARE ALLOWABLE UNDER 15 O.S.1981 § 217.
The majority rule is that unreasonable restraints are prohibited and that reason[1171]*1171able restrictions will be enforced.4 At common law, all contracts restraining trade were void. Later, the rules were relaxed, and contracts founded upon reasonable limitations of time and place were upheld.5 In E.S. Miller Laboratories, Inc. v. Griffin, 200 Okla. 398, 194 P.2d 877, 879, 3 A.L.R.2d 519, 522 (1948), this Court considered the effect of the enactment of §§ 217-219 on the common law, and it determined that the common law rules which analyzed covenants not to compete based on their reasonableness did not survive the enactment of §§ 217-219.
However, this finding was eroded by Tatum v. Colonial Life & Accident Ins. Co., 465 P.2d 448, 451 (Okla.1970), which held that a limited restraint on trade did not violate § 217. In both Crown Paint Co. v. Bankston, 640 P.2d 948, 952 (Okla. 1981), cert. denied, 455 U.S. 946, 102 S.Ct. 1444, 71 L.Ed.2d 659 (1982) and Bd. of Regents v. Nat’l Collegiate Athletic Ass’n (NCAA), 561 P.2d 499, 508, 85 A.L.R.3d 953, 967 (Okla.1977), we found that § 217 invalidated only unreasonable restraints on the exercise of trade. Although the rule of reason6 which requires that in order to be valid, a covenant must be deemed reasonable by the court, had been incorporated as a matter of law into agreements falling within the parameters of 79 O.S.1981 § l,7 its application to § 217 was questionable before the Crown Paint and NCAA decisions.8
Some states having legislation similar to §§ 217-219 do not subscribe to the rule of reason.9 Nevertheless, this Court’s [1172]*1172rulings in Crown Paint and NCAA align Oklahoma with jurisdictions which have similar legislation and which weigh the reasonableness of restrictions to determine their enforceability.10 Section 217 prohibits only unreasonable restraints on the exercise of a lawful professsion, trade, or büsiness.

COVENANTS NOT TO COMPETE MAY NOT BE MODIFIED JUDICIALLY TO BRING THE CONTRACT WITHIN THE RULE OF REASON IF THE COURT WOULD BE REQUIRED TO SUPPLY ESSENTIAL CONTRACTUAL TERMS.
There is a division of authority concerning whether a restrictive covenant not to compete is void in toto,11 or whether it may be judicially modified.12 Modification is allowed in jurisdictions which enforce reasonable agreements.13 The modification principle allows courts to escape the rule of arbitrary refusal to enforce a covenant and serves to protect legitimate interests of the parties or the public.14 However, not all jurisdictions recognizing that reasonable restrictions are enforceable will rewrite the parties' agreements. Instead, these courts find that if a covenant not to compete contains an illegal or unenforceable clause, the whole covenant fails.15 Other courts while recognizing that judicial modification is appropriate refuse to modify agreements if the elements of the contract are so lacking that the court would be required to provide essential elements of the agreement.16 Courts are hesitant to rewrite contracts especially where no justification exists for [1173]*1173the restriction imposed.17
Because § 217 prohibits only those contracts in unreasonable restraint of trade, judicial modification is justified if the contractual defect can be cured by imposition of reasonable limitations concerning the activities embraced, time, or geographical limitations. However, the Court of Appeals’ imposition of a reasonable geographical limitation on the operation of the agreements did not cure: 1) the defects relating to accepting or servicing of clients;18 2) the agreements restricting Pickard from competing in lines of business unrelated to the insurance industry; or 3) those restricting the sale of any kind of insurance to Bayly clients. The contractual provisions relating to the activities embraced would have to be rewritten to cure these defects. Here, there is more amiss than can be reformed effectively.19
The Covenant Not to Compete20 provides that Pickard will not “solicit, accept for service, or receive any commissions, fees or income attributable to the sale of, insurance business of any kind or character ...” from any party who was a [1174]*1174client of the NBS group21 at any time within three years of termination of employment. The provision also restricts Pickard from performing any other service rendered by any member of the NBS Group for the same time period and covering the same parties.
The Employment Agreement22 forbids the solicitation or acceptance of insurance business from current clients of Harlan, but the provision is much broader than the one found within the Covenant Not to Compete. The Employment Agreement not only restricts Pickard’s activities with current clients; it also covers parties becoming clients during Pickard’s employment and any prospective insurance customers contacted while Pickard was employed with the company. The Buy-Sell Agreement23 is similar to the Covenant Not to Compete because it proscribes the sale of any kind of insurance to BMF customers, and it restricts Pickard’s participation in other fields in which the BMF Group may participate regardless if it is related to the sale of insurance.
Neither the Covenant Not to Compete nor the Buy-Sell Agreement stop at restricting the sale of the same type of insurance as that sold by Bayly to its existing clients as did the provision in Tatum. These contracts absolutely forbid the sale of insurance of any kind to Bayly affiliates clients. Although as an employee, Pickard participated only in the insurance industry, if upheld, the Buy-Sell Agreement would restrict his participation in any business in which Bayly might become involved. The restriction in the Employment Agreement is not limited to forbidding the sale of insurance to parties who are clients of Bayly during the three year period following termination of employment. It covers any parties becoming clients during Pickard’s nine years of employment with Bayly, and prospective clients contacted prior to Pickard’s termination.
[1175]*1175It is conceivable that the provision could restrict Pickard from selling insurance to parties who became clients during his tenure with the company but who have since ceased to do business with Bayly, or with potential insurance clients contacted by Bayly but who never became its clients. In addition, all three provisions not only restrict the solicitation of insurance business but also deny Pickard the right to accept for service Bayly clients that may contact him for the purchase of insurance. Where no active solicitation has occurred, restraint on an insurance agent’s dealings with former clients is unenforceable.24
Even those courts allowing modification refuse to supply essential elements in covenants in order to make them reasonable.25 The buy-sell agreement and the covenant not to compete contain provisions recognizing that the laws and public policies of the various states may differ and that portions of the covenants may be unenforceable in some jurisdictions. These provisions provide that the covenants may be altered or modified to conform with applicable state law. Bayly asserts that these provisions afford Oklahoma Courts the authority to modify the covenants.
Although the provisions may express the intent of the parties, that intent is not considered if a statute expressly declares certain contracts void.26 Unlawful contracts, in derogation of our statutes, will not be enforced by the courts.27 The insertion of a provision in the three agreements permitting modification does not alter the fact that the Court would have to rewrite the contracts to make them reasonable.
CONCLUSION
Courts cannot supply material terms of a contract or read in terms not contained therein.28 The Court of Appeals’ imposition of a reasonable geographical limitation limiting operation of the three agreements to Tulsa County did not cure the other material defects of the three provisions. Because these contracts would require material judicial alteration and the provision of essential terms in order to come within the rule of reason, the Court of Appeals erred in modifying the contract.
