Vanegas v. American Energy Services (Tex. 2009) (Green)
═══════════════════════════════════════════════════════════════════════
Argued October 15, 2008
Justice Green delivered the opinion of the Court.
In this case, we are asked to decide the enforceability of an employer’s alleged promise to pay five percent of the
proceeds of a sale or merger of the company to employees who are still employed at the time of the sale or
merger. The employer, American Energy Services (AES), argues that because these were at-will employees, any
promise was illusory and therefore not enforceable—the company could have avoided the promise by firing the
employees at any time. The employees respond that the promise represented a unilateral contract, and by
staying on with the company until AES Acquisition, Inc. acquired AES several years later, they performed on the
contract, making it enforceable. We agree with the employees; continuing their employment with the company
until it was sold would constitute performance under such a unilateral contract, making the promise enforceable,
regardless of whether that promise may have been considered illusory at the time it was made. We therefore
reverse the court of appeals’ judgment and remand the case to the trial court to consider the merits.
I
AES was formed in the summer of 1996. AES hired the petitioners in this case (collectively, the employees) that
same year. The employees allege that in an operational meeting in June 1997, they voiced concerns to John
Carnett, a vice president of AES, about the continued viability of the company. The employees complained that
the company required them to work long hours with antiquated equipment. The employees allege that, in an effort
to provide an incentive for them to stay with the company, Carnett promised the employees, who were at-will and
therefore free to leave the company at any time, that “in the event of sale or merger of AES, the original [eight]
employees remaining with AES at that time would get 5% of the value of any sale or merger of AES.” AES
Acquisition, Inc. acquired AES in 2001. Seven of the eight original employees were still with AES at the time of the
acquisition. Those remaining employees demanded their proceeds, and when the company refused to pay, the
employees sued, claiming AES breached the oral agreement.
AES moved for summary judgment on two grounds: that the agreement was illusory and therefore not
enforceable, and that it violated the statute of frauds.1 The employees responded that the promise represented
a unilateral contract, and by remaining employed for the stated period, the employees performed, thereby making
the promise enforceable. The trial court granted AES’s motion for summary judgment, and the employees
appealed. The court of appeals affirmed, holding that the alleged unilateral contract failed because it was not
supported by at least one non-illusory promise, citing this Court’s decision in Light v. Centel Cellular Co. of
Texas, 883 S.W.2d 642, 644–45 (Tex. 1994). 224 S.W.3d 544, 550 (Tex. App.—Eastland 2007). The employees
petitioned this Court for review, which we granted. 51 Tex. Sup. Ct. J. 771 (Apr. 18, 2008).
II
AES argues, and the court of appeals held, that our holdings in Light, 224 S.W.3d at 553, and Sheshunoff v.
Johnson, 209 S.W.3d 644 (Tex. 2006), dictate the result in this case. In Light, we stated:
Consideration for a promise, by either the employee or the employer in an at-will employment, cannot be
dependent on a period of continued employment. Such a promise would be illusory because it fails to bind the
promisor who always retains the option of discontinuing employment in lieu of performance. When illusory
promises are all that support a purported bilateral contract, there is no contract. 883 S.W.2d at 644–45 (citation
omitted). AES and the court of appeals also relied on two footnotes from that opinion to support their position. In
footnote five, we stated that “[a]ny promise made by either employer or employee that depends on an additional
period of employment is illusory because it is conditioned upon something that is exclusively within the control of
the promisor.” Id. at 645 n.5. And in footnote six, we noted “[i]f only one promise is illusory, a unilateral contract
can still be formed; the non-illusory promise can serve as an offer, which the promisor who made the illusory
promise can accept by performance.” Id. at 645 n.6.
Light involved an employee’s challenge to a covenant not to compete. Id. at 643. Approximately two years after
being hired, Light, an at-will employee, executed a covenant not to compete with her employer. Id. Relying on the
Covenants Not to Compete Act, Tex. Bus. & Com. Code § 15.50(a), the employer, United Telespectrum, sought
to enforce the covenant against Light after she left the company. Id. The Act provides that “a covenant not to
compete is enforceable if it is ancillary to or part of an otherwise enforceable agreement at the time the
agreement is made.” Tex. Bus. & Com. Code § 15.50. We held that “[a]lthough Light and United did have an
otherwise enforceable agreement between them, the covenant was not ancillary to or a part of that otherwise
enforceable agreement.” Light, 883 S.W.2d at 643. We concluded that the agreement included only three non-
illusory promises: “(1) United’s promise to provide ‘initial . . . specialized training’ to Light; (2) Light’s promise to
provide 14 days’ notice to United to terminate employment; (3) Light’s promise to provide an inventory of all
United property upon termination.” Id. at 646. We held that Light’s promise not to compete with her employer
upon termination was not enforceable because it was not “ancillary to or a part of” the non-illusory promises; that
is, the covenant not to compete was “not designed to enforce any of Light’s return promises in the otherwise
enforceable agreement.” Id. at 647. We concluded that because Light’s promise failed to meet the requirements
of the Act, the covenant not to compete was not enforceable. Id. at 647–48.
We revisited the issue of illusory promises in covenants not to compete in Sheshunoff. In that case, an
employer again sought to rely on the Covenants Not to Compete Act to enforce a covenant against a former
employee. 209 S.W.3d at 646. We reaffirmed our previous holding in Light that covenants not to compete in
bilateral contracts must be supported by “mutual non-illusory promises.” Id. at 649. We observed that unlike the
employee in Light, Sheshunoff did receive promised confidential information in exchange for his promise not to
disclose that information following termination. Id. We noted, though, that under footnote six of Light, this
agreement would still be considered invalid because Sheshunoff was an at-will employee, and his employer could
have fired him before providing him with the confidential information; therefore, the agreement was not
enforceable at the time it was made, but rather it was only enforceable once they provided this information to him.
Id. at 650. We overruled that portion of Light’s holding, noting that this was not the intent of the Act: “[W]e
disagree with footnote six insofar as it precludes a unilateral contract made enforceable by performance from
ever complying with the Act because it was not enforceable at the time it was made.” Id. at 650–51.
Citing our holdings in Light and Sheshunoff, the court of appeals stated that “[a] unilateral contract may be
formed when one of the parties makes only an illusory promise but the other party makes a non-illusory promise.
The non-illusory promise can serve as the offer for a unilateral contract, which the promisor who made the
illusory promise can accept by performance.” 224 S.W.3d at 549 (citing Sheshunoff, 209 S.W.3d at 650, and
Light, 883 S.W.2d at 645 n.6). We agree with that statement, but the court of appeals erroneously applied those
holdings to the current case.
The issue turns on the distinction between bilateral and unilateral contracts. “A bilateral contract is one in
which there are mutual promises between two parties to the contract, each party being both a promisor and a
promisee.” Hutchings v. Slemons, 174 S.W.2d 487, 489 (Tex. 1943) (quoting Restatement (First) of Contracts §
12). A unilateral contract, on the other hand, is “created by the promisor promising a benefit if the promisee
performs. The contract becomes enforceable when the promisee performs.” Plano Surgery Ctr. v. New You
Weight Mgmt. Ctr., 265 S.W.3d 496, 503 (Tex. App.—Dallas 2008, no pet.); see also Light, 883 S.W.2d at 645 n.
6; 1 Richard A. Lord, Williston on Contracts § 1.17 (4th ed. 2007) (“A unilateral contract occurs when there is
only one promisor and the other party accepts, not by mutual promise, but by actual performance or
forbearance.”). Both Sheshunoff and Light concerned bilateral contracts in which employers made promises in
exchange for employees’ promises not to compete with their companies after termination. Sheshunoff, 209 S.W.
3d at 649 (“ASM promised to disclose confidential information and to provide specialized training under the
Agreement, and Johnson promised not to disclose confidential information.”); Light, 883 S.W.2d at 645 (“When
illusory promises are all that support a purported bilateral contract, there is no contract.”) (emphasis added). The
court of appeals’ explanation of these cases—describing an exchange of promises where one party makes an
illusory promise and the other a non-illusory promise—describes the attempted formation of a bilateral contract,
not a unilateral contract. 224 S.W.3d at 549. Our discussion in footnote six of Light was confined to situations
where a non-illusory promise could salvage an otherwise ineffective bilateral contract by transforming it into a
unilateral contract, enforceable upon performance. This was not a blanket pronouncement about unilateral
contracts in general.2
The court of appeals held that even if AES promised to pay the employees the five percent, that promise was
illusory at the time it was made because the employees were at-will, and AES could have fired all of them prior to
the acquisition. 224 S.W.3d at 549. But whether the promise was illusory at the time it was made is irrelevant;
what matters is whether the promise became enforceable by the time of the breach. See Sheshunoff, 209 S.W.3d
at 651 (“[A] unilateral contract formed when the employer performs a promise that was illusory when made can
satisfy the requirements of the [Covenants Not to Compete] Act. . . . There is no sound reason why a unilateral
contract made enforceable by performance should fail under the Act.”); see also 2 Joseph M. Perillo & Helen
Hadjiyannakis Bender, Corbin on Contracts § 6.2 (1995) (“[U]nilateral contract analysis is applicable to the
employer’s promise to pay a bonus or pension to an employee in case the latter continues to serve for a stated
period.”). Almost all unilateral contracts begin as illusory promises. Take, for instance, the classic textbook
example of a unilateral contract: “I will pay you $50 if you paint my house.” The offer to pay the individual to paint
the house can be withdrawn at any point prior to performance. But once the individual accepts the offer by
performing, the promise to pay the $50 becomes binding. The employees allege that AES made an offer to split
five percent of the proceeds of the sale or merger of the company among any remaining original employees.
Assuming that allegation is true, the seven remaining employees accepted this offer by remaining employed for
the requested period of time. See City of Keller v. Wilson, 168 S.W.3d 802, 824 (Tex. 2005) (holding that, in
reviewing a summary judgment, we “examine the entire record in the light most favorable to the nonmovant,
indulging every reasonable inference and resolving any doubts against the motion”). At that point, AES’s promise
became binding. AES then breached its agreement with the employees when it refused to pay the employees
their five percent share.
Furthermore, the court of appeals’ holding would potentially jeopardize all pension plans, vacation leave, and
other forms of compensation made to at-will employees that are based on a particular term of service. Corbin on
Contracts observed as much in discussing the court of appeals’ opinion in this case:
The court’s analysis may attempt to prove too much. The argument that a promise to grant a raise to a
terminable-at-will employee is necessarily illusory raises the question, why is an employer’s original promise to
pay a certain wage to an at-will employee enforceable when the employee performs? The court’s analysis would
suggest that the employer’s promise was never enforceable. If an at-will employee is hired at a promised
compensation and performs for some period, the court’s analysis would suggest that the promised rate of
compensation was never enforceable.
1 John E. Murray, Jr. & Timothy Murray, Corbin on Contracts § 1.17 (Supp. Fall 2009). We agree that the court of
appeals’ opinion could have far-reaching adverse effects on well-established forms of compensation.
The fact that the employees were at-will and were already being compensated in the form of their salaries in
exchange for remaining employed also does not make the promise to pay the bonus any less enforceable.
It is now recognized that these are not pure gratuities but compensation for services rendered. The employer’s
promise is not enforceable when made, but the employee can accept the offer by continuing to serve as
requested, even though the employee makes no promise. There is no mutuality of obligation, but there is
consideration in the form of service rendered. The employee’s one consideration, rendition of services, supports
all of the employer’s promises, to pay the salary and to pay the bonus.
2 Corbin on Contracts § 6.2; see also Elizabeth T. Tsai, Annotation, Promise By Employer to Pay Bonus as
Creating Valid and Enforceable Contract, 43 A.L.R.3d 503 (1972) (listing cases from several states upholding
validity of employers’ promises to pay bonuses in exchange for employees’ future service). By remaining with the
company, the employees gave valuable consideration. See 1 Williston on Contracts § 1.17 (“The performance or
forbearance constitutes both acceptance of a promisor’s offer and consideration.”). Therefore, any promise to
pay sale or merger proceeds became an enforceable unilateral contract when the employees performed.
III
AES allegedly promised to pay any remaining original employees five percent of the proceeds when AES was
sold. Assuming AES did make such an offer, the seven remaining employees accepted the offer by staying with
AES until the sale. Regardless of whether the promise was illusory at the time it was made, the promise became
enforceable upon the employees’ performance. The court of appeals erred in holding otherwise. Accordingly, we
reverse the court of appeals’ judgment and remand the case to the trial court for further proceedings consistent
with this opinion. Tex. R. App. P. 60.2(d).

OPINION DELIVERED: December 18, 2009
--------------------------------------------------------------------------------
1 AES has since expressly abandoned its statute of frauds defense. See Tex. Bus. & Com. Code § 26.01(b)(6).
2 In fact, Williston on Contracts disapproves of the use of the term “unilateral contract” to describe an agreement
in which one of the promises in a bilateral contract fails:
[T]he term unilateral contract should be reserved for cases in which a legal obligation has been created, but only
one party to the obligation has made a promise. When there is no obligation, the transaction may be a unilateral
promise or a unilateral offer, but it cannot properly be called a unilateral contract. Thus, for example, when the
promisor seeks a return promise and obtains an illusory promise, his or her own undertaking may properly be
characterized as unilateral; but since no enforceable obligation exists, it is not properly called a unilateral contract.
