Corporate Shareholder Agreement Governance-Override Requirements in Maine

At a glance

Requirements one by one

Maine gives the agreement corporation-binding override effect

The route applies to a domestic corporation for profit or with shares under 13-C M.R.S. § 102(7). A compliant agreement is effective among the shareholders and the corporation even when inconsistent with another Business Corporation Act provision. It may eliminate or restrict the board, govern distributions, set directors and officers, divide voting power, govern property or service arrangements, transfer management or deadlock authority, require dissolution, or govern other corporate relationships not contrary to public policy (13-C M.R.S. § 743(1)).

The distribution override remains subject to 13-C M.R.S. § 651(3), which bars a distribution that would leave the corporation unable to pay debts as due or fail the stated balance-sheet test.

Adoption is unanimous; amendment has a no-board exception

The agreement may appear in the articles or bylaws if all current shareholders approve it. Alternatively, every current shareholder signs a writing made known to the corporation. Amendment defaults to all shareholders at the time unless the agreement provides otherwise or Section 743(8) governs (13-C M.R.S. § 743(2)).

If no shares have issued, incorporators or subscribers may act as shareholders. Shareholder includes a beneficial owner to the extent of rights granted by a nominee certificate on file with the corporation (13-C M.R.S. §§ 102(30),(34), 743(7)).

Maine defaults to an unlimited term

Section 743(2) makes the agreement valid for an unlimited term unless it provides otherwise. The statutory effect ends when the corporation becomes public, using the three-part federal-securities definition in 13-C M.R.S. § 102(24): exchange listing, specified covered-security status, or Exchange Act Section 12 registration.

Notice and rescission use Maine-specific details

The agreement's existence must be conspicuously noted on outstanding share certificates or the cross-referenced information statement. Existing certificates must be recalled and replaced. Missing notice does not invalidate the agreement or an action taken under it (13-C M.R.S. § 743(3)).

An unknowing purchaser may rescind. A compliant notation supplies deemed knowledge; for uncertificated shares, the information statement also must be delivered by the time of purchase. Maine uses the earlier of 180 days after discovery or two years after purchase—not the ninety-day discovery clock used by many Model Act states. Section 627(2) separately requires the corporation to send an uncertificated shareholder the specified written statement within a reasonable time after issue or transfer.

Eliminating the board creates a second statutory layer

If the articles eliminate the board, shareholders are deemed directors when the Act's context requires, receive director powers, and bear director-law liability when taking required director action. They approve those actions by share vote, not per capita vote (13-C M.R.S. § 743(8)(A)-(C)).

Deleting that articles provision defaults to a majority of votes entitled to be cast by each separate voting group. A compliant shareholder agreement may vary the subsection's principles. The certificate-notice rule does not apply to shareholder-managed certificates issued before the Act's effective date, but it does apply to later certificates and information statements (13-C M.R.S. § 743(8)(D)-(F)).

Separately, an agreement that shifts board discretion relieves directors and places corresponding director-law liability on the persons receiving the power. Agreement performance, partnership-like treatment, or failure to observe covered formalities is not by itself a ground for shareholder personal liability (13-C M.R.S. § 743(5)-(6)).

What trips people up

Maine does not use a ten-year default. The current statute says the term is unlimited unless the agreement provides otherwise.

The purchaser discovery clock is 180 days, not ninety. The independent two-year purchase clock remains.

Public-corporation status is broader than an IPO or exchange listing. Current Section 102 also includes specified covered securities and equity securities registered under Exchange Act Section 12.

Common questions

Must the corporation sign the agreement?

No corporation signature is stated. The separate-writing route requires all current shareholders to sign and requires the agreement to be made known to the corporation; the articles or bylaws route uses unanimous current-shareholder approval (13-C M.R.S. § 743(2)(A)).

Does a missing certificate notation void the agreement?

No. Section 743(3) preserves the agreement and actions taken under it, while giving an unknowing purchaser the separate rescission protection.

Are shareholder-directors counted per person when the board is eliminated?

No. For corporate action taken in their director role under Section 743(8), the shareholders vote their shares rather than voting per capita.
