If you haven't read our previous article, 'What Is A Shareholder Agreement? A Complete Guide For Australian Companies', we recommend reading that introduction first before reading the below.


A shareholder agreement is one of the most important documents governing an Australian company. While no two agreements are the same, certain clauses are essential to ensure clarity, protect shareholder rights, and reduce the risk of disputes.


Let's explore the key clauses every shareholder agreement should include, and why each one matters.

Share Ownership And Structure


These clauses record who owns which shares in the company, the classes of shares on issue (such as ordinary or preference shares), and the rights attached to those shares, including voting, dividend and liquidation entitlements. Clearly defining ownership and share rights promotes transparency and helps prevent disputes about control or value later on.


Buy-Sell Provisions


Buy-sell provisions define the rights and responsibilities of shareholders when it comes to buying or selling shares under specific circumstances, such as insolvency, disability, death or retirement. These provisions typically include a clear pricing or valuation mechanism to ensure fair transactions (we'll discuss this later as well)


Often regarded as one of the most critical elements of a shareholder agreement, buy-sell provisions are especially important for minority shareholders in closely held private companies. Without them, minority shareholders may have limited or no ability to sell their shares, making these provisions a key tool for protecting their interests.


Board Composition And Management


A shareholder agreement should set out how the board is structured, including the size of the board, how directors are appointed or removed, and how board meetings operate.


In some cases, director appointment rights are reserved for founding or substantial shareholders to maintain stability and continuity in the company’s management.


Decision-Making And Voting Thresholds


An effective shareholder agreement distinguishes between decisions made by the board in the day-to-day running of the business and decisions that require shareholder approval because they are fundamental to the company.


Depending on the nature of the decision, approval may require a simple majority, a special majority, or unanimous consent. These voting thresholds are particularly important for protecting minority shareholders.


Funding Obligations


The agreement should clearly explain whether shareholders are required to contribute capital to the company, how additional funding will be sourced (if and when required), and whether funding will be provided by way of equity, loans or a combination of both. Addressing funding obligations upfront can avoid conflict if the company experiences cash flow pressure.


Issue Of Shares And Anti-Dilution Rights


Most shareholder agreements include pre-emptive rights, requiring new shares to be offered to existing shareholders before they are issued to third parties. Without these protections, the issue of new shares can significantly dilute a shareholder’s ownership and control of the company.


Transfer Of Shares And Restrictions


Shareholder agreements commonly restrict when and how shares can be sold or transferred. These restrictions may include requiring shareholder consent, granting pre-emptive rights on transfers, and preventing shares from being sold to competitors or unknown third parties. These provisions ensure shareholders retain control over who they go into business with.


Drag-Along And Tag-Along Rights


Drag-along and tag-along provisions regulate how shares are sold in an exit scenario. Together, these clauses balance flexibility with protection.


  • Drag-along rights allow majority shareholders to require minority shareholders to sell their shares on the same terms in a sale of the company.


  • Tag-along rights protect minority shareholders by allowing them to participate in a sale initiated by the majority and receive the same price and conditions.


Exit Events


A shareholder agreement should clearly define what constitutes an exit event, such as the sale of the company, a merger or acquisition, liquidation or an initial public offering. The agreement should also address how exit events occur and how shares are valued when they do.


Vesting And Employee Shareholders


Vesting provisions allocate shares gradually rather than all at once, often based on continued employment, performance milestones, or time-based criteria. Vesting is commonly used in startups to incentivise and retain key employees by aligning their interests with the long-term success of the business.


An options pool allows employees or contractors to acquire shares in the company at a later date if certain conditions are met. While options can be an effective recruitment and retention tool, they also dilute founders’ equity and should be carefully structured within the shareholder agreement.


Valuation Of Shares


Disputes frequently arise over the value of shares. A well-drafted shareholder agreement should clearly set out how shares are to be valued, whether an independent valuer is required, and how disagreements about valuation will be resolved.


Dispute Resolution And Deadlock Provisions


To minimise the risk of litigation, shareholder agreements usually require disputes to be resolved through structured processes such as good-faith negotiation, mediation and arbitration (if necessary).


In companies with equal ownership, buy-sell or 'shotgun' clauses are particularly important for resolving deadlocks and preventing business paralysis.


Exit Of Employee Shareholders


Where a shareholder is also an employee, the shareholder agreement will usually require their shares to be sold back to the company if they cease employment.


The price payable often depends on whether the employee is classified as a 'good leaver' or a 'bad leaver', with significantly different outcomes depending on the circumstances of their departure.


Common Mistakes to Avoid


  • Using Generic Templates

    Generic or online templates rarely reflect the specific needs of your business or the intentions of the shareholders. They often overlook critical issues or include unenforceable provisions that can fail when a dispute arises.


  • Failing To Address Deadlock

    Deadlock can prevent a company from making essential decisions, particularly where shareholders have equal ownership. Without clear mechanisms to resolve it, the business can become effectively paralysed.


  • Leaving Valuation Clauses Vague

    Unclear valuation provisions are a common source of shareholder disputes, especially on exit. A lack of certainty around how shares are valued can lead to delays, disagreement and increased legal costs.


  • Waiting Until Conflict Arises

    Negotiating a shareholder agreement after tensions have emerged is far more difficult and costly. Agreements are most effective when put in place early, before disputes develop.


  • Assuming A Constitution Alone Is Sufficient

    A company constitution provides general governance rules but limited shareholder protection. Unlike a shareholder agreement, it can usually be amended by majority vote and may not safeguard minority interests.


Need Advice On A Shareholder Agreement?


There is no 'one size fits all' shareholder agreement. Each agreement should be carefully tailored to the company’s structure, industry and the intentions of its shareholders. However, including the right clauses from the outset can significantly reduce risk and provide clarity throughout the life of the business.
