Key takeaways
- The purchase agreement is the document that determines the actual economics of the transaction, not the LOI. Terms that were agreed at a high level in the LOI are given precise definition in the purchase agreement, and the precision often favors the buyer's drafting counsel.
- The four sections with the highest economic impact for sellers are: representations and warranties (what you are promising), indemnification (what you owe if a rep is wrong), the purchase price adjustment mechanics (how the final number is calculated), and the earnout provisions (if applicable).
- Disclosure schedules are part of the purchase agreement and carry the same legal weight. Errors or omissions in disclosure schedules can create indemnification exposure just as easily as errors in the reps themselves.
- The survival period for reps, how long after close the buyer can bring an indemnification claim, varies by rep category and is one of the most consequential terms for a seller's post-close exposure management.
- The gap between what was negotiated in the LOI and what appears in the first draft of the purchase agreement is almost always in the buyer's favor. Reading the agreement against the LOI term sheet before engaging in redline negotiations is the most important first step.
How to use this before a process
For adjacent context, compare this with How to build a management package buyers actually trust and How to Prepare for Management Presentations to Private Equity Buyers; the strongest operators connect these topics instead of treating them as separate workstreams.
Rule of thumb: if a buyer will ask for it in diligence, build it before the process. The same work costs less, creates more confidence, and carries more valuation benefit when it is completed before exclusivity.
Earnout Terms to Lock Before LOI
- Define the metric, measurement period, accounting rules, and dispute process in writing.
- Model the payout at base, downside, and buyer-controlled operating scenarios.
- Cap overhead allocations and integration charges that can move the metric after close.
- Require reporting access during the earnout period, not just after a missed payout.
- Know what happens if the buyer sells, merges, or reorganizes the acquired business.

The average lower-middle-market purchase agreement for a stock purchase transaction is 80–150 pages plus exhibits and schedules. The sections that carry the highest economic risk for sellers represent approximately 30–40% of the document by page count but are disproportionately dense and cross-referenced.
In post-close M&A disputes, 68% of indemnification claims arise from alleged breaches of representations and warranties that were not adequately disclosed in the disclosure schedules, meaning the claim was not about a hidden problem but about a known problem that was inadequately disclosed or characterized in the schedules.
Founders who reviewed the purchase agreement against the LOI term-by-term before engaging in redline negotiations identified an average of 4–7 material deviations from the LOI terms in the first draft, compared to 1–2 identified by those who relied entirely on counsel's summary.
The <a href="/insights/letter-of-intent-ma-founder-guide" class="subtle-link">letter of intent</a> describes a deal. The purchase agreement is the deal. The difference between those two statements is meaningful: the LOI contains agreed-upon economic parameters (price, structure, key terms) at a level of generality that allows both parties to move forward. The purchase agreement converts those parameters into precise legal language, and precise legal language, drafted by the buyer's counsel as the starting point, consistently favors the buyer.
Founders who read the purchase agreement personally, not just the counsel summary, but the actual document, discover terms that affect their post-close life in ways their attorneys may not have flagged as priorities.

The structure of a purchase agreement: what is where
A purchase agreement follows a relatively standard structure across lower-middle-market transactions. Understanding the architecture allows a founder to navigate the document efficiently and find the sections that matter most.
Purchase Agreement Structure: What Each Article Contains
Article 1: Definitions
The most important section to read first. Every capitalized term used throughout the agreement is defined here. "EBITDA," "Closing Date," "Material Adverse Effect," "Knowledge," "Indebtedness," and "Working Capital" may all have definitions that differ from their common usage. A definition that includes or excludes a specific item can determine the outcome of a later dispute.
Article 2: Purchase and Sale / Transaction Structure
Describes what is being purchased (stock or assets), the purchase price and how it is calculated, the closing mechanics, and the purchase price adjustment mechanism (working capital peg, earnout, if applicable). This article sets out the financial structure of the deal.
Article 3: Representations and Warranties of the Seller
The seller's factual statements about the business. Every rep in this section is a potential indemnification obligation if false. The breadth of the reps, the materiality qualifiers, and the knowledge qualifiers (does "to seller's knowledge" limit the rep?) determine the seller's exposure.
Article 4: Representations and Warranties of the Buyer
The buyer's reps, authority to close, financing availability, no conflicts. Typically shorter and less consequential for the seller than Article 3.
Article 5: Covenants
Obligations both parties must fulfill before and after closing. Pre-close covenants: how the seller must operate the business between signing and closing. Post-close covenants: confidentiality, further assurances, non-compete, employee matters.
Article 6: Conditions to Closing
What must be true for each party to be obligated to close. Seller's conditions (buyer must have funding, reps must be accurate) and buyer's conditions (seller reps must be accurate, no material adverse change, required consents obtained).
Article 7: Indemnification
How post-close claims are handled. Basket (deductible), cap, survival periods, escrow mechanics, R&W insurance interaction, and specific indemnities for known issues. This article determines the seller's total post-close financial exposure.
Article 8: Miscellaneous
Governing law, dispute resolution, notice provisions, amendment procedures. Less economically significant but legally important.
The five provisions that most commonly surprise sellers
After the main structural terms (price, structure, working capital), these are the provisions that most commonly contain terms that differ materially from what the seller expected based on the LOI.
Read every definition in Article 1 before reading any other article. The definitions section is where the buyer's counsel embeds the most consequential changes from the LOI. A definition of "Indebtedness" that includes unfunded pension obligations, accrued but unpaid bonuses, and transaction expenses can reduce the net purchase price by $500K–$2M relative to a narrower definition. This is the section where deals get repriced silently.
Five Purchase Agreement Provisions That Frequently Surprise Sellers
1. The definition of "Indebtedness" and "Transaction Expenses"
These definitions determine what is deducted from the gross enterprise value to calculate the cash payment to the seller at close. Definitions drafted by buyers routinely include items the seller did not anticipate: accrued vacation liability, deferred revenue that must be refunded, customer deposits, unfunded pension obligations, and transaction bonuses. Each inclusion reduces the seller's net proceeds.
2. The "Material Adverse Effect" (MAE) definition
The MAE definition governs when the buyer can walk away from the transaction after the LOI is signed and before closing. A broad MAE definition favors the buyer; a narrow one protects the seller. What is included and excluded from the MAE definition (industry-wide conditions, pandemic-type events, changes in law) determines how much risk the seller retains during the pre-close period.
3. The knowledge qualifier in representations
Many reps are qualified by "to the seller's knowledge." The definition of "knowledge", whether it is limited to actual knowledge or includes constructive knowledge (what the seller should have known), and whose knowledge counts (just the founder or also the CFO and key managers), directly affects the seller's exposure for reps that the company's officers knew about but the founder did not personally know.
4. The indemnification basket and its structure
The basket (sometimes called a deductible) is the threshold below which the buyer cannot bring indemnification claims. There are two types: a "deductible" basket (claims must exceed the threshold before any recovery, like a true deductible) and a "tipping" basket (once claims exceed the threshold, the buyer recovers from dollar one). The difference on a $150K basket with $160K of claims: deductible basket = $10K recovery; tipping basket = $160K recovery.
5. The earnout calculation definition
If the deal includes an earnout, the definition of the earnout metric (EBITDA, revenue, or another measure) in the purchase agreement is the controlling document. LOIs often describe earnout metrics at a high level; the purchase agreement must define every component: what is included and excluded from revenue, how overhead is allocated in EBITDA, which accounting policies govern, and who resolves disputes. Any ambiguity in the earnout definition will resolve in favor of the party with post-close control, the buyer.

Run an AI readiness scan →How to review a purchase agreement against the LOI
The most effective way for a founder to engage with a purchase agreement is to review it term-by-term against the LOI before the redline process begins. This review does not require legal training, it requires only the LOI, the purchase agreement, and the willingness to identify where the precise language differs from the agreed general terms.
A Founder's LOI-to-Purchase-Agreement Review Checklist
Purchase price and adjustments
Does the purchase price as defined match the LOI? Is the working capital peg definition consistent with what was negotiated? Is the Indebtedness definition broader than anticipated?
Earnout provisions (if applicable)
Does the earnout metric definition match the LOI? Are the overhead allocation protections negotiated in the LOI present in the purchase agreement language? Is the dispute resolution mechanism defined?
Non-compete terms
Does the duration match the LOI? Does the geographic scope match the actual operating footprint? Is the activity scope defined narrowly enough to permit the founder's intended post-sale activities?
Indemnification: basket and cap
Does the basket match the LOI amount? Is it a deductible or tipping structure? Does the cap match the LOI amount? Are there exceptions to the cap for fraud, fundamental reps, or specific indemnities?
Survival periods
How long do the general reps survive? How long do the fundamental reps (ownership, authority, capitalization) survive? How long do the tax reps survive? Are these consistent with what was discussed?
R&W insurance interaction
If R&W insurance was agreed, is the indemnification structure consistent with the policy structure? Does the seller's retention match the policy retention?
Disclosure schedules
Are the disclosure schedules complete? Do they accurately reflect every known exception to every rep? Are there reps with broad language that require a disclosure but where the schedule is blank?
A founder signed an LOI for a $16M stock purchase transaction.
The LOI defined the purchase price as "$16M enterprise value, adjusted for working capital and net debt." During purchase agreement review, the founder identified that the buyer's definition of "Indebtedness" included: accrued vacation liability ($180K), unpaid transaction bonuses ($220K), and a customer deposit the buyer argued was a refundable liability ($95K). None of these had been discussed at the LOI stage. Total impact: $495K reduction in net cash to seller. The founder's counsel successfully excluded the transaction bonuses (a separate buyer responsibility) and negotiated a narrower treatment of the customer deposit, recovering $290K of the $495K gap.
The $205K remaining deduction was accepted. Without the founder's personal review of the Indebtedness definition against the LOI, the $495K deduction would have passed unnoticed.
Common purchase agreement mistakes that cost sellers value
Frequently asked questions
What should a founder do first?
Identify the specific buyer concern this topic creates and assemble the documents that prove the answer. The goal is to make the diligence response evidence-based before a buyer asks the question.
Why does this matter in a sale process?
Because buyers convert uncertainty into price, structure, or diligence friction. A documented answer reduces the perceived risk and keeps the discussion focused on value rather than cleanup.
What is the most common mistake?
Waiting until after LOI exclusivity to fix the issue. At that point the buyer has leverage, the timeline is compressed, and every gap is interpreted through a risk-adjustment lens.
