Letter of Intent Clauses US Businesses Should Understand

For US startups and small business owners, receiving or drafting a letter of intent (LOI) is a common milestone when negotiating a business deal. Whether you are considering selling your business, entering a partnership, or securing a large contract, a LOI can help both sides set expectations before investing significant time and money. However, many founders and operators make the mistake of treating LOIs as informal or always non-binding, only to discover later that certain clauses can be enforced in court. Others sign LOIs without negotiating key terms or understanding how state law could affect their rights. This guide explains what a letter of intent is, why it matters, and which clauses US businesses should always review. We cover practical examples, checklists, state law caveats, and common mistakes to help you approach LOIs with confidence.

What Is a Letter of Intent?

A letter of intent is a written document that outlines the preliminary terms and intentions of parties involved in a potential business transaction. LOIs are used in a wide range of deals, including mergers and acquisitions, joint ventures, commercial leases, and large supply or service agreements. The main purpose of a LOI is to ensure both sides are generally aligned on the key deal points before moving forward with detailed contracts and due diligence.

LOIs typically cover the following:

• The main business terms (such as price, structure, or partnership goals)
• Timelines for negotiation and closing
• Obligations during due diligence
• Confidentiality and exclusivity requirements
• Which terms are binding and which are not

Importantly, a LOI is not the same as a final contract. However, some clauses in a LOI can be legally binding, while others are only statements of intent. How a LOI is interpreted depends on its wording, the parties' conduct, and the state law that applies. For example, a LOI governed by Delaware law may be treated differently than one under California or Texas law.

Example: A SaaS startup receives a LOI from a potential acquirer. The LOI lists a proposed purchase price, sets a 60-day exclusivity period, and requires both sides to keep negotiations confidential. The founder assumes the LOI is entirely non-binding, but the exclusivity and confidentiality clauses are actually enforceable under the governing state law.

Common Letter of Intent Clauses

While LOIs can vary widely depending on the type of deal and industry, several clauses appear in most US LOIs. Understanding these clauses, and knowing which are likely to be binding, is critical before signing.

• Binding vs. Non-Binding Provisions: Most LOIs specify which terms are binding (such as confidentiality or exclusivity) and which are not (such as the purchase price or deal structure). This distinction is crucial. If a LOI does not clearly label each section, courts may interpret ambiguous language as binding based on the parties' intent and conduct.
• Confidentiality: This clause requires both parties to keep the details of negotiations and any shared information private, even if the deal does not close. It often survives the termination of the LOI.
• Exclusivity (No-Shop): An exclusivity clause prevents one or both parties from negotiating with others for a set period. This can give the other party leverage and should be negotiated carefully. For sellers, long exclusivity periods can tie up your business and limit your options.
• Key Deal Terms: These include the proposed price, payment structure, closing date, and any conditions that must be met before a final agreement is signed. While usually non-binding, the language used can affect enforceability.
• Due Diligence: This outlines what information will be shared, how long the process will take, and what happens if issues are discovered. It may also include obligations to provide access to financials, contracts, or intellectual property.
• Termination: This clause explains how either party can walk away from the LOI and under what circumstances. It may also address what happens to confidential information or exclusivity obligations after termination.
• Governing Law: Specifies which state's laws will apply if there is a dispute. This can have a major impact on how the LOI is interpreted and enforced.
• Break Fees or Penalties: Some LOIs include a fee if one party walks away without cause. These are more common in larger deals but can appear in smaller transactions as well.
• Non-Solicitation: Clauses that prevent the parties from hiring each other's employees or soliciting customers if the deal does not close. Enforceability varies by state.

Checklist: Key Clauses to Review in a LOI

• Are binding and non-binding terms clearly labeled?
• Is the confidentiality clause reasonable and limited in scope?
• Does the exclusivity period make sense for your business?
• Are there any break fees or penalties, and are they enforceable in your state?
• Does the LOI specify the governing law?
• Are due diligence obligations clear and manageable?
• Is there a clear process for terminating the LOI?

Binding vs. Non-Binding Clauses: How to Tell the Difference

One of the most common mistakes US founders make is assuming a letter of intent is always non-binding. In reality, LOIs often mix binding and non-binding terms. For example, the parties may agree that the purchase price is non-binding, but the confidentiality and exclusivity clauses are binding and enforceable in court.

Here is how to spot the difference:

• Binding Clauses: These create legal obligations. If you breach a binding clause, the other party can potentially sue for damages or seek an injunction. Common binding clauses include confidentiality, exclusivity, non-solicitation, and sometimes dispute resolution or governing law.
• Non-Binding Clauses: These are statements of intent or proposed deal terms. They generally cannot be enforced in court if the deal falls through. Examples include the proposed purchase price or a non-binding summary of the transaction structure.

To avoid confusion, LOIs should clearly label each section as "binding" or "non-binding." If it is not clear, ask for clarification or suggest edits. Some state courts may interpret ambiguous LOIs as binding if the language suggests the parties intended to be legally obligated. For example, using words like "shall" or "agree to" can create enforceable promises, even if the parties intended otherwise.

Practical Example: A founder receives a LOI that says, "The parties agree to negotiate in good faith to finalize the transaction." In some states, this language may be interpreted as a binding obligation to negotiate, even if the deal terms are otherwise non-binding. In New York, for instance, courts have enforced "agreements to negotiate in good faith" in certain cases, while California courts are generally more reluctant to do so.

Checklist:

• Highlight any clause that mentions obligations, restrictions, or penalties.
• Ask whether the clause is meant to be binding or non-binding.
• Request that the LOI explicitly state the binding status of each key term.
• Be cautious of vague language or terms that could be interpreted as commitments.
• Check the governing law and research how that state treats LOIs.

Common Mistake: Signing a LOI with ambiguous language, only to discover later that a court considers certain terms binding based on your conduct or the wording used.

Key Clauses to Watch in US Letters of Intent

Let's look at some of the most important clauses US startups and small businesses should review in a LOI, with practical examples and negotiation tips:

• Confidentiality: Make sure you understand what information is covered, how long the obligation lasts, and any exceptions (such as disclosures required by law). For example, if you share trade secrets during due diligence, the confidentiality clause should protect them even if the deal falls through. Some states, like California, have specific rules about the enforceability of confidentiality agreements, especially if they are overly broad or restrict employee mobility.
• Exclusivity (No-Shop): This clause can prevent you from talking to other potential partners or buyers for a set period. Negotiate the duration and scope. If you are a seller, be wary of long exclusivity periods that tie up your business without a firm commitment. In Texas, for example, courts generally enforce exclusivity clauses if they are clear and reasonable in duration.
• Break Fees or Penalties: Some LOIs include a fee if one party walks away without good reason. These are more common in larger deals but can appear in smaller transactions. Make sure you understand when fees apply and whether they are enforceable under your state's law. In Delaware, break fees are generally enforceable if they are reasonable and not punitive.
• Access to Information: The LOI may specify what documents or data you must provide during due diligence. Limit access to only what is necessary and protect sensitive information. For example, you might agree to provide financial summaries but withhold customer lists until a binding agreement is signed.
• Employee or Customer Non-Solicit: Some LOIs include clauses preventing the other party from poaching your employees or customers if the deal does not close. Review these carefully, as enforceability varies by state. In California, for instance, non-solicitation clauses related to employees are often unenforceable.
• Governing Law and Dispute Resolution: The LOI should specify which state's law applies and how disputes will be resolved (for example, through arbitration or court litigation). This can have a major impact on your rights if a dispute arises.

Practical Example: A SaaS startup receives a LOI from a strategic investor. The LOI includes a 90-day exclusivity clause and a requirement to provide detailed customer data. The founder negotiates the exclusivity period down to 30 days and limits the customer data to anonymized summaries until a binding agreement is signed.

Checklist: Negotiating LOI Clauses

• Negotiate the duration and scope of exclusivity clauses.
• Limit confidentiality to specific information and set a reasonable time frame.
• Clarify when break fees or penalties apply, and check their enforceability in your state.
• Restrict access to sensitive information during due diligence.
• Review non-solicitation clauses for compliance with state law.
• Ensure the governing law clause reflects a state you are comfortable with.

Common Mistake: Agreeing to a broad exclusivity clause that prevents you from talking to other buyers for months, only to have the deal fall through and lose momentum in the market.

Risks and Pitfalls When Signing a Letter of Intent

Signing a LOI is often seen as a low-risk step, but it can create legal and business risks if not handled carefully. Here are some common pitfalls US startups and operators should watch for:

• Unintended Binding Terms: Accidentally agreeing to binding terms you did not intend, such as a non-compete or a break fee.
• Overly Broad Confidentiality: Agreeing to keep information confidential without clear limits, which can restrict your future business activities.
• Long or Unclear Exclusivity: Being locked out of other opportunities for too long, or not knowing when exclusivity ends.
• Ambiguous Language: Vague terms can lead to disputes about what was agreed or whether the LOI is enforceable.
• State Law Differences: Some states, like New York and California, interpret LOIs more strictly than others. Always check which state's law applies and how courts in that state treat LOIs.
• Failure to Negotiate: Treating a LOI as a take-it-or-leave-it document and missing the chance to negotiate terms that protect your interests.
• Sharing Too Much Information: Providing sensitive data before a binding agreement is in place, which can expose your business if the deal falls through.

Checklist: Before Signing a LOI

• Are all binding and non-binding terms clearly labeled?
• Does the LOI expose my business to unnecessary risk or limit my options?
• Have I reviewed the LOI with a legal professional familiar with the relevant state law?
• Is the exclusivity period reasonable and clearly defined?
• Does the confidentiality clause allow for necessary disclosures (such as to advisors or as required by law)?
• Are break fees or penalties reasonable and enforceable?
• Have I limited the information I am required to share during due diligence?

Common Mistake: Signing a LOI without understanding the enforceability of its clauses under the governing state law, leading to unexpected legal obligations or disputes.

FAQs

Is a letter of intent legally binding in the US?

It depends on the wording of the LOI and the state law that applies. Most LOIs include both binding and non-binding clauses. For example, confidentiality and exclusivity clauses are often binding, while the main deal terms may not be. Courts look at the language used and the parties' intent. Always review the LOI carefully and clarify which terms are binding before signing.

Can I negotiate the terms of a letter of intent?

Yes, you can and should negotiate LOI terms. Key areas to negotiate include the duration and scope of exclusivity, the extent of confidentiality, what information must be shared during due diligence, and any break fees or penalties. Do not assume the LOI is a take-it-or-leave-it document, propose changes that protect your interests.

What happens if I breach a binding clause in a LOI?

If you breach a binding clause, such as confidentiality or exclusivity, the other party may have grounds to sue for damages or seek an injunction. The specific remedies depend on the language of the LOI and the governing state law. Even if the main deal does not go ahead, breaching a binding clause can have legal and reputational consequences.

Should I sign a LOI before talking to a lawyer?

It is generally a good idea to review a LOI with a lawyer, especially if you are unsure which clauses are binding or if the deal involves significant risks. A legal professional can help clarify the terms, suggest edits, and explain how state law might affect your rights and obligations.

Can a LOI include a non-compete or non-solicitation clause?

Yes, some LOIs include non-compete or non-solicitation clauses, especially in deals involving the sale of a business or key employees. However, enforceability varies by state. For example, California generally prohibits non-compete clauses, while other states may enforce them if they are reasonable in scope and duration. Always check the governing law and consult a legal professional before agreeing to these terms.
