Preliminary documents — NDA, IOI, LOI.

The preliminary documents are the legal infrastructure that supports the deal before the definitive purchase agreement is drafted. NDA, IOI, and LOI each serve different purposes; the disciplined buyer uses each at the right stage and resists pressure to skip steps that protect the buyer's position.

Mutual, time-limited, standard-form.

The Non-Disclosure Agreement establishes the confidentiality framework for the information exchange. Standard provisions cover.

• Mutual obligation. Both buyer and seller protect the other's confidential information. Asymmetric NDAs (buyer-protective only or seller-protective only) signal an unbalanced negotiation; standard practice is mutual.
• Defined scope. What information is protected — financial data, customer lists, employee information, carrier-relationship details, strategic plans. Carve-outs for publicly-available information and information independently developed.
• Time-limited. Most NDAs expire 2–3 years after signing. Standstill provisions (the buyer can't approach the seller's employees or customers post-NDA failure) may extend longer.
• Standstill provisions. Optional but common in agency M&A. Buyer agrees not to approach employees or customers for a defined window if the deal doesn't progress. Protects the seller from buyer-side opportunistic hiring or client poaching after diligence access.

NDA signing should precede any substantive information exchange. Sellers who share book reports, financial statements, or producer data before NDA execution are taking on diligence-access risk without protection.

Optional but useful for competitive deals.

The Indication of Interest is the buyer's pricing communication before the LOI's binding commitment. Useful when the seller has multiple bidders and is narrowing the field; less useful in bilateral negotiations where the LOI follows quickly.

The IOI typically contains:

IOIs are sometimes skipped — bilateral negotiations often move from NDA directly to LOI. The IOI is most useful when the seller is running a structured process with multiple bidders and needs to narrow to a short list before exclusivity.

Exclusivity, range, walk-away conditions.

The Letter of Intent is the primary protective architecture before the definitive purchase agreement. Most LOI provisions are non-binding (the price range, the diligence scope, the closing timeline) — but specific provisions are binding and structurally protect both sides through the diligence window.

The binding provisions:

• Exclusivity / no-shop. Seller agrees not to engage with other potential buyers during the exclusivity period. The buyer's protection against the seller using the buyer's price to leverage better terms from competitors. Typically 45–90 days; shorter is better when the buyer is prepared.
• Confidentiality reinforcement. Often references the existing NDA and strengthens its provisions for the diligence period.
• Expense allocation. Each side bears its own expenses except in specifically-defined scenarios (broken-deal fees, expense reimbursement on material adverse changes).
• Walk-away conditions. Material adverse change, regulatory consents not obtained, financing not committed, diligence findings outside negotiated tolerance. Specific enumeration prevents post-LOI dispute.

The non-binding LOI provisions include the price range, the deal structure outline, the diligence scope, the closing timeline, and any specific seller-side commitments (carrier consent, producer recommitment, regulatory remediation as closing conditions). These are framework — not commitments — but they establish what the parties intend to negotiate around.

The preliminary-documents layer feeds the purchase-agreements layer (the definitive agreement architecture). Together they form the legal-architecture framework. The Pillar — Legal Architecture — covers the broader framework.
