Background
Matthew Frankenfeld was hired as Chief Development Officer by Thrive Physical Therapy Partners in April 2023 under a written offer letter. The offer letter included provision for equity compensation through a separate Incentive Award Agreement, expressly conditioning Frankenfeld’s participation on “the execution and delivery of customary equity award agreements.” The parties engaged in extensive negotiations regarding the Incentive Agreement from June 2023 through January 2024. Frankenfeld requested modifications in December 2023 regarding vesting terms; Thrive agreed and transmitted a revised agreement on January 30, 2024. Frankenfeld signed the revised agreement on February 6, 2024, and emailed it to Thrive’s representative, who acknowledged receipt and promised a countersigned copy but never provided one.
In February–May 2024, Thrive demanded Frankenfeld invest $175,000 in Class B units (instead of the previously agreed $40,000). When Frankenfeld declined, Thrive stated it would not honor the Incentive Agreement. Frankenfeld’s employment access was cut off on May 14, 2024. Frankenfeld sued seeking a declaratory judgment that the Incentive Agreement was valid and enforceable and specific performance requiring issuance of 223,000 Class C equity units. Thrive moved to dismiss under section 2-615 of the Illinois Code of Civil Procedure, arguing that mutual execution was a condition precedent to contract formation and that condition was never satisfied.
The Court’s Holding
The appellate court affirmed the dismissal, holding that Frankenfeld’s signature alone was insufficient for contract formation. The court analyzed the structure and language of the Incentive Agreement, identifying multiple provisions indicating that mutual execution was a condition precedent to enforceability. The agreement included signature blocks for both parties, the closing language “IN WITNESS WHEREOF, the parties hereto have executed this Incentive Award Agreement,” Section 1(b) conditioning the issuance of equity units on satisfaction of additional requirements, Section 3(c) representing that execution has been “duly authorized” and constitutes a “binding obligation,” and Section 8(e) contemplating execution “in two or more counterparts.” These provisions collectively demonstrated the parties’ intent that the agreement would not become binding upon preliminary assent or negotiation, but only upon completion of formal execution by both sides.
The court rejected Frankenfeld’s arguments that contract formation could occur through conduct. While acknowledging that Illinois courts recognize contracts may be formed by conduct (as in Calo, Inc. v. AMF Pinspotters, Inc.), the court distinguished that case because it involved no prescribed mode of acceptance and the seller’s conduct directly performed the contract’s terms. Here, Thrive’s acknowledgment of receipt and promise of a countersigned copy reflected ordinary negotiation, not binding conduct, and crucially, where parties expressly contemplate mutual execution as a condition precedent, that condition must be satisfied—conduct cannot substitute for it. The court also rejected Frankenfeld’s waiver argument, holding that Thrive’s refusal to countersign reflected failure of contract formation, not wrongful hindrance of an existing contract. Under Jordan v. Busch, waiver principles apply only where a binding contract already exists; they cannot transform an unexecuted agreement into an enforceable contract.
Key Takeaways
- Formal mutual execution is a binding condition precedent to contract formation when the agreement’s text and structure expressly contemplate it, particularly through signature blocks, “IN WITNESS WHEREOF” language, and provisions assuming execution has occurred.
- One party’s signature and performance under an agreement does not create binding obligations if mutual execution is a stated condition precedent and the other party never executes.
- Acknowledgment of receipt and oral assurances of countersignature constitute ordinary negotiation, not conduct demonstrating mutual assent sufficient to overcome an express execution requirement.
- Where equity compensation is conditioned on execution of a separate agreement distinct from the employment offer, performance and conduct under the offer letter do not extend to the unexecuted equity agreement.
- Waiver and estoppel doctrines do not apply to cure the failure of contract formation; they presuppose an already-existing binding contract.
Why It Matters
This decision significantly impacts employment and equity compensation disputes, particularly in startup and growth-stage contexts where equity packages are common. Frankenfeld clarifies that executives and employees cannot rely on partial performance, acknowledgment of equity agreements, or oral assurances to establish binding equity rights if the underlying agreement is unsigned. The court’s strict adherence to the plain language of agreements requiring mutual execution means that companies can protect themselves by ensuring their equity agreements expressly condition enforceability on full execution, while employees must ensure both parties actually execute equity documents—not merely sign them personally or receive oral promises of countersignature.
The decision also reinforces a principle important to contract drafting generally: the structure and language of an agreement strongly influence whether a court will find mutual execution essential to formation. This gives parties significant control over contract enforceability at the drafting stage. For employees in disputes over promised equity, the ruling emphasizes the necessity of obtaining fully executed agreements rather than relying on partial documentation or assurances that additional signatures will follow. The court’s rejection of conduct-based formation arguments where execution conditions are express means that absent clear evidence both parties intended to waive the execution requirement—a very high bar—the failure to obtain mutual signatures will be fatal to an equity claim.
