MEMORANDUM OPINION AND ORDER
Plaintiff Applied Micro, Inc', brought suit in this Court claiming that its former customer, SJI Fulfillment, Inc. (SJI), and former employee, Janice Schmitt, breached their re-' spective contracts with AMI when Schmitt left the company to work for SJI. Schmitt’s employment with SJI allegedly violated her covenant not to compete with AMI by soliciting its customers. Conversely, in employing Schmitt, SJI allegedly breached its written agreement to refrain from hiring AMI employees. The gist of AMI’s claim is that it spent time and money training Schmitt to program computers using a specialized language, reposed trust in her as its sole employee proficient in that language, and executed two contracts to protect its investment, only to lose Schmitt when its customer, SJI, transformed AMI’s temporary assignment into SJI’s permanent employment. Minus Schmitt, AMI has allegedly been unable to provide computer support to customers that purchased programs using the specialized language. As a result, AMI claims, it has lost a substantial chunk of business.
These allegations are incorporated into a three-count complaint. Count One details *752 S JI’s alleged breach of contract. Count Two elaborates on Schmitt’s alleged violation of the restrictive covenant. Count Three seeks to hold SJT additionally liable for interfering with AMI and Schmitt’s contractual relations.
Currently before this Court is defendant Schmitt’s motion to dismiss, which targets only Count Two. Schmitt contends that this count is deficient because the restrictive covenant on which it is based is unenforceable. Her objection to the covenant rests on the sole ground that it is not ancillary to a valid employment contract and, therefore, serves only the impermissible purpose of restraining trade. For the reasons discussed below, we find that the covenant withstands this attack. 1 Accordingly, defendant Schmitt’s motion to dismiss is denied.
RELEVANT FACTS 2
Schmitt began working for AMI as a computer systems programs analyst on March 30, 1987. Compl. ¶ 3. About a month later, on April 27, Schmitt signed an “Employee Noncompete Agreement.” Id. ¶ 4. The agreement prohibited Schmitt from soliciting any customers or accounts that belonged to AMI at the time she worked there, for a period of one year following her termination. Id. Ex. A. Other .than the restrictive covenant, no written employment agreement governed the terms and conditions of Schmitt’s employment; her relationship with AMI was purely at-will.
Shortly after Schmitt executed the covenant not to compete, AMI allegedly trained her, at its own expense, in programming using a specialized computer language called “Progress” and its corresponding application, “Varnet.” Id. ¶ 5. Schmitt was subsequently designated AMI’s sole Progress/Varnet programmer, allegedly generating over $200,000 each year in Progress/Varnet sales and service. Id. ¶¶ 6-7. For the next five years, Schmitt remained AMI’s lone Progress/Varnet-literate employee. Id. • ¶ 24; Pl.Resp.Mot.Dismiss at 2. She focused primarily on writing individualized programs in the Progress language for AMI customers and providing them the necessary support services. Id.
In May of 1992, AMI executed a sales agreement with SJI to develop for it a customized computer program using Progress/Varnet. Compl. ¶ 8 & Ex. B. In addition to setting forth the parties’ obligations with respect to AMI’s computer services, the agreement prohibited SJI from offering jobs to AMI employées for two years following its execution. Id. ¶ 9 & Ex. B ¶ 11.
Schmitt was immediately assigned to the SJI project. Later that month, she began working on-site at SJI’s offices in St. Louis during part of each week to implement the computer system. Id. ¶¶ 10-11. This arrangement continued for several months. Id. ¶ 12. But on November 16, before Schmitt had completed the project, SJI offered her a full-time job. Id. ¶¶ 13-14. One month later, Schmitt accepted the position with SJI, where she remains today. Id. ¶¶ 14, 17. All told, Schmitt worked at AMI for five-and-a-half years. Id. ¶¶ 3,14.
AMI claims that by accepting employment with SJI, Schmitt breached her obligation under the noncompete agreement to refrain from soliciting AMI’s customers. Schmitt rejoins with the argument that she cannot be held to the noncompete because it is unenforceable under Illinois law. The remainder of this opinion is dedicated to resolving this solitary dispute.
ANALYSIS
I. Legal Standards
Schmitt filed her motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), which requires the Court to accept all well-pleaded allegations as true, and draw all reasonable inferences in favor of the plaintiff, AMI.
Travel All Over the World, Inc. v. Kingdom of Saudi Arabia,
The validity of a restrictive covenant is a question of law, and more particularly, of state law.
Agrimerica, Inc. v. Mathes,
Illinois courts have devised a test for evaluating the enforceabiUty of restrictive covenants in the employment context. Such covenants are generaUy enforceable if reasonable in geographic and temporal scope and necessary to protect the employer’s legitimate business interest.
Abel v. Fox,
274 Ill.pp.3d 811, 813,
N.E.2d 379, 384 (1st Dist.1990). Before proceeding with a reasonableness analysis, however, the court must make a threshold determination: it must find 1) that the covenant is anciUary to a vaUd employment contract and 2) that it is supported by adequate consideration.
Abel,
II. The AppeUate Court SpUt
Schmitt argues that her noncompete is not ancülary to a vahd employment agreement because she was not furnished a contract setting forth the terms and conditions
*754
of her employment, including its length and her compensation. Indeed, she contends, AMI’s failure to promise a specific period of employment in exchange for executing the noncompete alone strikes a fatal blow. Schmitt cites one case in her entire supporting memorandum, the First Appellate District’s
Creative Entertainment
decision, in favor of this proposition. But AMI quite correctly points out that
Creative Entertainment
does not comprise the judicial universe on the validity of restrictive covenants, and, in fact, was called into serious question just one year later by the Fourth. Appellate District in
Abel v. Fox.
The
Abel
court held that an oral at-will relationship is a valid employment “contract” or “relationship” that complies with the requirement of ancillary.
In
Creative Entertainment,
the First District struck down a noncompete on ancillarity grounds, and dismissed the count on which it was based, because no written contract specified the defendant’s terms and conditions of employment. Defendant Lorenz had been employed at will, and the only written agreement he executed was a non-compete signed eight months after he began working. When Lorenz left to form his own business, and began contacting his former employer’s customers in violation of the agreement’s provisions, the employer sued to enforce the covenant. Finding the noncompete unenforceable as a matter of law, the court stated that to be ancillary to a valid employment contract, the covenant had to be “subordinate to the contract’s main purpose.”
In contrast,
Abel v. Fox
held that an oral at-will arrangement is a valid contract or “relationship” that satisfies the ancillarity requirement.
It is clear that these decisions create a split between two appellate districts over what kind of employment relationship is a valid foundation for a covenant not to compete. The Illinois Supreme Court has never addressed this issue, so this Court must choose between the appellate decisions. Two alternative approaches exist to facilitate this choice: predicting how the state supreme court would rule or applying the law of the *755 appellate district in which the federal court sits.
III. Determining State Law When Appellate Decisions Conflict
Schmitt points out the irony that a second split exists, among judges in the Northern District of Illinois, over the appropriate method of determining state law under Erie when the state appellate districts are diametrically opposed on an issue and the supreme court is silent. Judge Shadur champions a geographical rule: following the district in which the federal court is located. 5 Judge Prentice Marshall, on the other hand, along with the majority of his peers, the Central District of Illinois, and arguably the Seventh Circuit, would make an effort to predict the state supreme court’s stance. 6 Schmitt does not advocate one approach over the other, but maintains that either analysis would render the covenant unenforceable. This Court finds, however, that its Erie obligations are best discharged under the supreme-court-predictive approach, and further, that the supreme court would uphold the noncompete under the rule set forth in Abel.
Judge Marshall favors the predictive approach over the geographical approach for a number of reasons. First, he interprets
Erie
to require that federal courts sitting in diversity obey the state law that would ultimately apply were the case litigated to its fruition before the highest state court.
Roberts,
Ultimately, the geographical approach leads to forum shopping, precisely the evil
Erie
sought to prevent.
Id.
at 540-41;
Kelly,
When the rights of a litigant aré dependent upon the law of a particular state, the court of the forum must do its best (not its worst) to determine what that law is. It must use its judicial brains, not a pair of scissors and a paste pot. Our judicial pro *756 cess is not mere syllogistic deduction, except at its worst.
Id.
(quoting Arthur Corbin,
The Laws of Several States,
50 Yale L.J. 762, 775 (1941),
cited in Warner v. Gregory,
Judge Shadur is concerned that the predictive approach has the potential to defeat litigants’ justified expectations.
Commercial Discount,
While Judge Shadur does make a well-reasoned case for the geographic approach in his
Commercial Discount
and
Abbott Laboratories v. Granite State Insurance Co.
opinions, we consider the predictive method more faithful to
Erie.
We think the Seventh Circuit would agree, given its statement that state appellate court decisions on questions of state law “provide us with data for ascertaining the relevant Illinois law, but may be disregarded if we are ‘convinced by other persuasive data that the highest court of the state would decide otherwise.’ ”

IV. The Supreme Court Would Enforce the Restrictive Covenant
Guidelines do exist to aid the Court in predicting how the state supreme court would rule in this case. We begin with supreme court precedent, and examine authority on point, analogous cases, the policies and doctrinal trends that influenced those decisions, and the court’s “considered dicta,” in that order.
Roberts,
As discussed in
Abel,
the Illinois Supreme Court has expressed its approval of restrictive covenants that protect the fruits of one party’s efforts from unjust use by the other party. In
More v. Bennett,
An analogy is thereby sought to be raised between the contract in this case and those contracts in partial restraint of trade, which the law upholds____ Contracts in partial restraint of trade which the law sustains are those which are entered into by a vendor of a business and its goodwill with his vendee____ But in the present case there is no purchase or sale of any business, nor any other analogous circumstance giving to one party a just right to be protected against competition from the other.
Id.
at 80,
Schmitt nevertheless argues that Illinois courts entertain a “general opposition to restrictive covenants,” and for that reason, the supreme court would adopt the
Creative Entertainment
rationale to strike down Schmitt’s noncompete. Def. Reply at 6-7. However, Schmitt cites not one supreme court case to support this contention, and in fact constructs a circular argument by relying exclusively on
Creative Entertainment. More
and
Union Trust’s modern
progeny defy Schmitt’s depiction of a “general opposition” to noncompetes. The supreme court has upheld a covenant restraining a veterinarian from practicing for five years within thirty miles of his former employer, finding the plaintiffs interest in protecting his clients a legitimate basis for the noncompete.
Cockerill v. Wilson,
Not only does supreme court precedent support Abel’s conclusion that employment relationships, no matter how configured, may be supplemented by noncompetes, but persuasive authority solidifies it. As Abel points out, section 187 of the Restatement (Second) of Contracts directly supports allowing non-competes despite the. absence of a written contract: “A promise to refrain from competition that imposes a restraint that is not ancillary to an otherwise valid transaction or relationship is unreasonably in restraint of trade.” Restatement (Second) op Contracts § 187, at 38 (1979) (emphasis added). Comment b to section 187 explains that the promisee’s interest may arise out of “a relation between himself as employer or principal and the promisor as employee or agent,” and says nothing about the need for an employment contract setting forth specific terms of employment. Finally, comment g to section 188 is right on point: “A restraint may be ancillary to a relationship although, as in the case of an employment at will, no contract of employment, is involved.” Restatement (Second) op Contracts § 188 comment g, at 45 (1979).
These authorities, compiled in the
Abel
decision, recognize that pitting employment by contract against employment at will makes a distinction without a difference. The Seventh Circuit has said as much, noting that “[ejmployment at will is of course a valid contractual relationship.”
Curtis,
The facts in this case, viewed in the light most favorable to AMI and under the law that the supreme court would apply, demonstrate that Schmitt’s noncompete was ancillary to the employment relationship. The purpose of the noncompete was not simply to restrain trade, but rather to protect AMI’s customer base. Schmitt was allegedly the only employee at AMI capable of programming in the Progress language. In this capacity, she generated hundreds of thousands of dollars each year. for AMI. When she departed, she deprived AMI not only of S JI’s business, but the patronage of all AMI’s other customers that had purchased the Progress/Varnet package, depending on AMI’s expertise to implement it. Like the employer in Cockerill, AMI was entitled to prevent its clients from being appropriated by its former employee. And like the doctor in Canfield, Schmitt was presented opportunities by working at AMI, which trained her in the Progress language and introduced her to SJI, that she might not otherwise have had.
*758 Schmitt argues that if we decline to follow Creative Entertainment and uphold her non-compete, we will be ignoring the “underlying evil” that the case attempts to cure. Def.Reply at 7. Specifically, such a decision would purportedly enable employers to ask an existing at-will employee to sign a restrictive covenant, fire the at-will employee right afterward, and still enforce the restrictive covenant. Id. This argument is without merit. It ignores the long line of cases, which our decision does not disturb, requiring continued employment for a substantial period after the employee signs the noncompete. An employer in the situation posited by Schmitt would clearly be unable to enforce the restrictive covenant for lack of consideration.
Our decision that the supreme court would favor the reasoning and result in
Abel
over
Creative Entertainment
is strengthened by the fact that
Creative Entertainment
cites no supreme court cases or persuasive authority for its conclusion, and is even inconsistent with one of its own earlier decisions. In
Agrimerica, Inc. v. Mathes,
the First District rebuffed challenges to a noncompete’s consideration and ancillarity despite the fact the challenger was an at-will employee.
In sum,
Creative Entertainment
is out of step with precedent, persuasive authority, and policy. Because we have determined that the supreme court would in all likelihood share our view, we decline to accept
Creative Entertainment’s
invitation to adopt a legal perspective that would strike down all non-competes in at-will employment relationships. Rather, the enforceability of covenants not to compete in at-will arrangements is “based on the same rules which apply to any other post-employment noncompetition covenant made during an employment relationship.”
Abel,
CONCLUSION
For the foregoing reasons, defendant Schmitt’s motion to dismiss Count II is denied.
Notes
. ' The opinion addresses only the objections Schmitt raises in her memoranda.
. The facts are derived from AMI's complaint, whose allegations we must accept as true in deciding motions to dismiss.
See Doherty v. City of Chicago,
. For a thorough explanation as to why courts view continued employment as good consideration for a covenant not to compete, see
Curtis,
This convention, however, is not without its limits. For example, employment for just seven months after executing a noncompete does not provide the requisite consideration.
See MidTown Petroleum, Inc. v. Gowen,
. Schmitt belatedly challenges the noncompete’s consideration in her reply memorandum. This argument was waived when it was1 omitted it from her opening brief.
Wilson v. O’Leary,
.
See, e.g., KNS Co. v. Federal Ins. Co.,
.
See, e.g., Roberts v. Western-Southern Life Ins. Co.,
. Judge Marshall points out that this result is in contravention of the well-settled doctrine that a federal district court's construction of state law is entitled to great weight on appellate review when state courts have not authoritatively resolved the issue.
