Key Distinction: LOI vs Term Sheet
A Letter of Intent (LOI) uses narrative business-letter format for relationship-focused deals, typically 3-8 pages. A Term Sheet uses bullet-point format for complex or institutional deals, typically 2-5 pages. Both are 90% non-binding-only exclusivity, confidentiality, and expense provisions are enforceable.

Binding vs Non-Binding Provisions
Critical Distinction
Both LOIs and term sheets mix binding and non-binding provisions. The key difference is how clearly each document delineates what's enforceable.
Typical Binding Provisions (Both Documents)
- Exclusivity/No-Shop: 30-90 day exclusive negotiation period
- Confidentiality: NDA provisions and restrictions
- Expenses: Who pays for what costs
- Governing Law: Jurisdiction for disputes
- Break-up Fees: Penalties for walking away (sometimes)
Typical Non-Binding Provisions
- Purchase price and payment terms
- Deal structure (asset vs stock)
- Representations and warranties
- Closing conditions
- Indemnification terms

Where LOIs and Term Sheets Fit in the Deal Process
One of the most common questions: does the LOI or term sheet come first? The answer depends on deal type.
Institutional and PE Deals (IOI → Term Sheet → LOI → Purchase Agreement)
In competitive auctions or PE-backed transactions, the typical sequence starts with an Indication of Interest (IOI), a non-binding 1-2 page letter expressing preliminary interest and a valuation range. After management presentations and initial diligence, the buyer submits a detailed term sheet. If terms align, the parties execute a formal LOI with binding exclusivity, then move to the definitive purchase agreement.
Owner-Operated and Mid-Market Deals (LOI → Purchase Agreement)
In direct negotiations between a buyer and a business owner, buyers typically skip the IOI and term sheet entirely. The LOI serves as both the initial expression of interest and the deal-terms document. This is faster, less formal, and better suited to sellers who would find a multi-document process excessive.
Negotiation Traps Your Attorney Should Catch
Whether you use an LOI or term sheet, these five provisions cause the most problems between signing and closing. Each one can erode deal value or create leverage imbalances that surface too late to fix.
1. Premature Exclusivity
Sellers lose their strongest leverage the moment they grant exclusivity. If a buyer locks up 60-90 days of exclusivity before economics are finalized, the seller has no competitive pressure to push back on price adjustments during diligence. Best practice: cap exclusivity at 45 days, require written consent for extensions, and don't grant exclusivity until purchase price, structure, and key terms are agreed.
2. Headline Price vs. Net Proceeds
A $10M purchase price can become $7M at closing after escrow holdbacks (10-15%), earn-out deferrals, working capital adjustments, and seller-funded indemnification baskets. Both LOIs and term sheets should specify the escrow percentage, holdback duration, working capital target, and earn-out measurement method upfront. If these details are "to be determined in the purchase agreement," you've lost your negotiating window.
3. Vague Earn-Out Metrics
Earn-outs tied to "revenue" or "EBITDA" without specifying GAAP vs. non-GAAP, add-backs, or accounting methodology create post-closing disputes in the majority of cases. Best practice: specify the accounting standard, require quarterly reporting to the seller on earn-out metrics, and define who has audit rights over the earn-out calculation.
4. Open-Ended Diligence Scope
Without a defined diligence scope and cutoff date, buyers can extend investigations indefinitely, using minor findings as leverage to renegotiate price. Sellers should insist on a diligence request list within the first week and a hard cutoff date in the LOI or term sheet. Any diligence findings that affect valuation should require written notice before the cutoff, not at the closing table.
5. Break-Up Fee Ambiguity
"Reasonable expenses" is not a cap. Break-up fees and expense reimbursement provisions should specify a dollar amount or percentage of deal value, with clear triggers for when the fee applies. Without a defined ceiling, a failed deal can generate six-figure expense claims from the other side's advisory team.
Strategic Considerations
Choose LOI When You Want To:
- Build trust and rapport with seller. Cap exclusivity at 45 days with written consent for extensions
- Keep legal costs lower initially. Budget $5K-$13K vs. $10K-$35K for term sheets
- Maintain flexibility in negotiations. Seek verbal alignment on key terms before sending redlines
- Move quickly to exclusivity. Wrap up term alignment and signed LOI in under three weeks
- Explain complex business rationale. Narrative format accommodates strategic context that bullet points can't convey
Choose Term Sheet When You Need To:
- Satisfy institutional investor requirements. Create a bid matrix to compare offers across multiple term sheets
- Document complex deal structures precisely. Include rolled equity terms, share class, and issuance price details
- Coordinate multiple parties efficiently. Bullet format lets each advisor review their section independently
- Set clear precedent for definitive docs. Require earn-out reporting quarterly with specified accounting methods
- Minimize ambiguity in terms. Include a diligence cutoff date to prevent scope creep
Common Mistakes to Avoid
LOI Mistakes
- ❌ Making price binding when shouldn't be
- ❌ Too much detail creating rigidity
- ❌ Unclear about binding provisions
- ❌ No expiration date
Term Sheet Mistakes
- ❌ Too technical for business owners
- ❌ Missing key business terms
- ❌ Inconsistent terminology
- ❌ Over-lawyering simple deals
Hybrid Approach: Best of Both Worlds
Some sophisticated buyers use a hybrid approach:
- Start with informal term sheet for internal alignment
- Convert to LOI format for seller presentation
- Attach term sheet as exhibit to LOI for precision
- Reference both documents in purchase agreement
Due Diligence Differences
The document type can affect due diligence scope. Track everything with our Due Diligence Tracker:
- LOI deals: Often broader, more exploratory DD
- Term sheet deals: More focused, confirmatory DD

Enforceability Under Michigan Law
Michigan courts recognize both LOIs and term sheets as preliminary agreements, but enforceability depends on the parties' demonstrated intent and specific language used in each document.
Michigan Contract Law Standards
- • Intent to be Bound: Michigan courts follow the Restatement (Second) of Contracts §27-29 in determining whether parties intended binding obligations
- • "Subject to" Language: Phrases like "subject to definitive agreement" create strong presumption of non-binding intent under Michigan case law
- • Partial Performance: Michigan recognizes promissory estoppel claims if one party materially relies on preliminary agreements
- • Statute of Frauds: Agreements for real property sales must be in writing per MCL 566.106; personal property over $1,000 under MCL 440.2201
Key Michigan Considerations
- • Exclusivity Provisions: Michigan courts will enforce no-shop clauses with clear duration and scope, even when other terms are non-binding
- • Confidentiality: NDA provisions in LOIs/term sheets are independently enforceable trade secret protections under Michigan Uniform Trade Secrets Act (MUTSA)
- • Break-up Fees: Penalty clauses may be unenforceable under Michigan law unless reasonably related to anticipated losses
- • Choice of Law: Michigan courts generally respect choice of law provisions unless Michigan has materially greater interest in dispute
⚖️ Michigan Legal Precedent
Key Case: In Michigan M&A transactions, courts have consistently held that preliminary agreements are enforceable only when:
- 1. Parties explicitly agree certain provisions are binding (clearly labeled/separated)
- 2. Essential terms are sufficiently definite for enforcement
- 3. Consideration exists for binding provisions (exclusivity = forbearance to negotiate)
- 4. No "subject to definitive agreement" language clouds binding provisions
Practical Tip: For Michigan deals, always use separate sections with headers like "BINDING PROVISIONS" and "NON-BINDING BUSINESS TERMS" to eliminate ambiguity.
12 Most Common Questions About LOI vs Term Sheet
1. Does the term sheet or LOI come first?
It depends on the deal type. In institutional and PE-backed transactions, the typical sequence is: Indication of Interest (IOI), then term sheet, then LOI with binding exclusivity, then definitive purchase agreement. The term sheet captures detailed deal mechanics before the parties commit to exclusivity. In owner-operated and mid-market deals, buyers usually skip the IOI and term sheet entirely, going straight to an LOI that serves as both the initial offer and the preliminary agreement. Neither approach is "wrong." The right sequence depends on buyer sophistication, deal complexity, and whether a competitive auction process is involved.
2. What is an Indication of Interest (IOI) and how does it relate to LOIs and term sheets?
An IOI is a non-binding 1-2 page letter expressing preliminary interest in acquiring a business, typically including a valuation range (not a specific price), proposed deal structure, financing overview, and timeline. IOIs precede both term sheets and LOIs in competitive processes. Think of it as the "first date" before commitment. Sellers use IOIs to narrow the field of buyers before granting access to detailed financials and management meetings. After reviewing IOIs, sellers invite selected buyers to submit more detailed term sheets or LOIs. IOIs are always non-binding and carry no exclusivity.
3. Can I use a term sheet for a small business acquisition?
Yes, but it may be overkill. Term sheets work for any transaction size, but for deals under $5M with unsophisticated sellers, an LOI is typically more appropriate. The seller may find term sheets intimidating or overly technical, potentially slowing negotiations. However, if you're an institutional buyer or need precise documentation for internal approvals, use a term sheet regardless of deal size.
4. Is a handshake deal legally binding in Michigan?
Maybe. Michigan recognizes oral contracts, but the Statute of Frauds requires written agreements for real estate and goods over $1,000. For M&A, relying on handshakes is extremely risky - you need written documentation. While parties can be bound by oral agreements under Michigan law, proving terms and intent is difficult. Always get preliminary terms in writing via LOI or term sheet, even for "friendly" deals.
5. What happens if I sign an LOI and then get a better offer?
Depends on your LOI's exclusivity/no-shop clause. If binding, you're contractually prohibited from entertaining other offers during the exclusivity period (typically 30-90 days). Violating this could expose you to damages or specific performance claims. If your LOI has no exclusivity provision, you're free to negotiate with others, though it's ethically questionable and may kill deal momentum. Under Michigan law, breach of exclusivity can result in liability even if other LOI terms are non-binding.
6. Do investors prefer LOIs or term sheets?
Institutional investors (VCs, PE firms) overwhelmingly prefer term sheets. The format allows efficient due diligence, clear documentation of complex structures, and easy comparison across multiple deals. Family offices and strategic corporate buyers are more flexible - they'll use either based on deal characteristics. If your buyer is a fund, expect them to insist on a term sheet regardless of your preference.
7. How detailed should my preliminary agreement be?
Goldilocks principle: not too much, not too little. You need enough detail to prevent misunderstandings and show serious intent, but not so much that you're essentially drafting the purchase agreement. Key terms to include: purchase price (or valuation method), deal structure (asset vs stock), payment terms, due diligence scope, exclusivity period, closing timeline, and major conditions. Leave representations, warranties, and indemnification details for the definitive agreement.
8. Can I negotiate an LOI after signing it?
Generally, yes - that's the point of making most provisions non-binding. The purchase price, structure, and business terms are almost always subject to due diligence and can be renegotiated. However, binding provisions (exclusivity, confidentiality, expenses) typically cannot be changed without both parties' consent. Material changes during DD may require an "amended and restated LOI." Under Michigan law, good faith renegotiation is permitted, but bad faith attempts to escape unfavorable preliminary terms may create liability.
9. What's the typical exclusivity period?
30-90 days for most middle-market deals. Simple transactions ($1-5M) often use 30-45 days. Complex deals ($50M+) may need 90-120 days. The period should align with your due diligence timeline - if you can't complete DD and negotiate definitive docs within the period, don't agree to it. Sellers sometimes grant shorter periods (30 days) with automatic extensions if buyer is progressing in good faith. Michigan deals tend toward 60-day periods as a reasonable compromise.
10. Should I hire a lawyer to review my LOI/term sheet?
Absolutely - this is not the place to save money. Even though most provisions are non-binding, binding clauses (exclusivity, confidentiality, break-up fees) create real legal obligations. A lawyer ensures: (1) binding vs non-binding provisions are clearly delineated, (2) you're not accidentally creating unintended obligations, (3) terms protect your interests, and (4) the document creates favorable precedent for definitive agreements. For Michigan deals, a lawyer familiar with Michigan contract law is essential. Budget $2,000-$5,000 for LOI review, $5,000-$15,000 for complex term sheets.
11. How long does it take to negotiate an LOI vs a term sheet?
LOI: 1-3 weeks from first draft to execution for most middle-market deals. Simple deals can be done in days if parties are motivated. Term sheet: 1-2 weeks for VC deals with standard terms, 2-4 weeks for complex M&A term sheets with unusual structures. Factors affecting timeline: party sophistication (experienced parties move faster), complexity of terms, number of stakeholders requiring approval, and negotiation dynamics. Michigan deals with local buyers/sellers often move faster than multi-state transactions requiring multiple law firm reviews.
12. What if the other party won't sign a preliminary agreement?
Red flag - proceed with extreme caution. Sophisticated parties understand the value of preliminary agreements for mutual protection. Refusal might indicate: (1) seller has other offers and wants flexibility, (2) buyer isn't serious, (3) party fears commitment even to non-binding terms, or (4) unrealistic expectations about maintaining complete flexibility. In Michigan business culture, refusing to sign an LOI/term sheet after substantive negotiations is unusual and often signals deal issues. Consider walking away or insisting on exclusivity before investing more time/money. If they won't commit to preliminary terms, they likely won't close.
