Corporate Shareholder Agreement Governance-Override Requirements in Illinois

At a glance

Requirements one by one

Every Illinois business corporation has the narrow Section 7.71 route

Section 7.71 permits shareholders to “unanimously agree in writing” on matters concerning corporate management. The protection has express boundaries: no fraud or apparent injury to the public or creditors may be present, and the agreement cannot violate clearly prohibitory statutory language (805 ILCS 5/7.71(a)).

The agreement is not invalid between its parties merely because it treats the corporation like a partnership or interferes with board discretion. It is specifically enforceable under equitable principles, but Section 7.71 remains cumulative with other statutes and common law rather than displacing them (805 ILCS 5/7.71(c)-(e)).

Article 2A adds a broader close-corporation agreement

Illinois close status requires more than a label. The corporation must be organized under or elect Article 2A, and the articles or an agreement among all shareholders must subject every issued share of each class to one or more Section 6.55 transfer restrictions (805 ILCS 5/1.80(s), 2A.05).

An existing corporation elects by articles amendment after its issued shares are or will be subject to qualifying transfer restrictions. Every outstanding share of every class must approve, either unanimously in writing or by vote (805 ILCS 5/2A.10).

Once qualified, all shareholders may enter a written agreement covering any phase of corporate affairs. Section 2A.40's examples are management, dividends or profit division, officer and director selection, qualifying transfer restrictions, voting requirements including unanimity, shareholder employment, and arbitration of shareholder or director deadlocks. The agreement may appear in the articles, bylaws, or a separate writing actually assented to by the shareholders (805 ILCS 5/2A.40(a)-(b)).

Notice determines whether later shareholders are bound

Under the ordinary Section 7.71 route, an agreement is ineffective against a nonparty shareholder unless that person actually knew of it when becoming a shareholder or its existence was conspicuously referenced on the share certificate or the Section 6.35 notice for uncertificated shares (805 ILCS 5/7.71(b)).

Article 2A uses a stronger certificate rule. A close-corporation certificate must state the transfer restrictions, shareholder qualifications, and existence of any Section 2A.40 agreement, or conspicuously offer the complete statement and agreement without charge on request. A person receiving or taking such a certificate is conclusively presumed to know the agreement's provisions (805 ILCS 5/2A.25(a)-(b)).

Close status affects amendment and continuation of close-only terms

Neither Section 7.71 nor Section 2A.40 sets a general agreement term, renewal period, or amendment formula. Article 2A nevertheless supplies a status-exit rule. Voluntary termination requires at least two-thirds of every outstanding class, unless the articles require more, and the corporation must terminate or amend shareholder-agreement provisions available only to close corporations (805 ILCS 5/2A.20(a)-(b)).

Close status also ends when the corporation files the required status deletion or when a qualifying transfer restriction is breached or removed without a timely cure proceeding. The corporation continues under the rest of the Act, but no longer under Article 2A (805 ILCS 5/2A.15).

The two agreement routes have different liability effects

Section 7.71 prevents partnership-like treatment or interference with board discretion from being, by itself, a basis for personal corporate-liability claims against employees, officers, directors, or shareholders. It does not state that director liability shifts to shareholders (805 ILCS 5/7.71(c)).

Section 2A.40(c) does. If a close corporation remains board-managed, an all-shareholder agreement may interfere with board discretion, but making that agreement imposes on the shareholders the liability Illinois law places on directors for managerial acts. The subsection does not state that the directors are relieved.

What trips people up

An Article 2A agreement is not itself the board-elimination mechanism. Section 2A.45 requires an articles provision for shareholder management instead of a board. Adding that provision requires all subscribers and record shareholders, or—if no shares have issued—all incorporators and subscribers. It also makes shareholders subject to all director liabilities and requires conspicuous certificate notice (805 ILCS 5/2A.45(a)-(b)).

Do not treat a missing share notice as a harmless formality. Under Section 7.71, it leaves a nonparty shareholder unbound unless actual knowledge existed when the person became a shareholder. Under Article 2A, compliant certificate language creates conclusive notice of the Section 2A.40 agreement (805 ILCS 5/2A.25, 7.71(b)).

Common questions

Must the corporation sign an Illinois Section 7.71 agreement?

Section 7.71 requires the shareholders to agree unanimously in writing but does not require the corporation to be a party. The close-corporation board- interference rule likewise permits an agreement solely among all shareholders or between all of them and a nonshareholder party (805 ILCS 5/2A.40(c), 7.71(a)).

Does Illinois prescribe a ten-year agreement term?

No fixed term appears in Section 7.71 or Section 2A.40. Article 2A instead requires close-only agreement provisions to be terminated or amended when the corporation voluntarily ends close status (805 ILCS 5/2A.20).

Is there a statutory purchaser rescission deadline?

No agreement-specific clock is stated. For an Article 2A transfer that breaches qualifying conditions, Section 2A.25(f) preserves whatever rescission or express- or-implied-warranty rights otherwise apply; it does not create a deadline.

Does becoming publicly traded automatically end either route?

Sections 7.71 and 2A.40 state no exchange-listing or regular-trading cutoff. Article 2A status instead depends on the close-corporation election and the qualifying transfer restrictions described in Section 1.80(s), subject to the termination rules in Sections 2A.15 and 2A.20.
