Convertible Note Purchase Agreement

A convertible note purchase agreement documents an investor's purchase of debt that may convert into equity, with interest, maturity, discount or cap, and default terms.

A useful document turns the parties' actual arrangement into measurable duties, approvals, timing, remedies, and a reliable execution record. Its terms should be reconciled to the transaction rather than copied from an unrelated form.

• A startup issues seed notes before a priced round
• Several investors buy notes in one financing
• A bridge round extends runway to a qualified financing

The document name alone does not determine the right structure. Consider a different instrument or qualified legal review when any of these conditions applies:

• Not a SAFE without maturity or interest
• Not an ordinary commercial loan with no conversion feature

Record exact facts before clauses are written. Names, authority, dates, amounts, defined terms, dependencies, and incorporated materials should be verifiable and consistent.

• Principal, interest, and maturity
• Qualified financing threshold and conversion formula
• Valuation cap, discount, and accrued-interest treatment
• Security, seniority, investor rights, and default

These decisions shape the allocation of responsibility and should not be left for boilerplate to decide:

• Whether conversion is automatic or elective
• How cap and discount interact
• What happens at maturity without financing
• Whether notes are secured or subordinated

• Note purchase and closing conditions
• Interest, maturity, and payment
• Automatic and optional conversion
• Default, acceleration, and ranking
• Securities representations and transfer limits

Every provision should use the same parties, dates, standards, defined terms, and document hierarchy. A clause that is reasonable by itself can still create a conflict when it is not reconciled with payment, default, termination, or another exhibit.

1. 01Describe the intended result and the relationship in plain language.
2. 02Confirm parties, authority, governing jurisdiction, dates, money, property, services, and approvals.
3. 03Resolve the key decisions and identify every schedule, exhibit, disclosure, consent, or filing.
4. 04Draft the provisions as one consistent system, then review the complete execution set before signature.

A convertible note remains debt until conversion under its terms; maturity and default can create repayment pressure. Conversion definitions must match all issuances and financing documents.

The main agreement may establish the framework while schedules, exhibits, disclosures, consents, or operational records supply transaction-specific details.

• Executed note form and purchase schedule
• Board approvals and cap table model
• Exemption and investor diligence records

Each incorporated document should be identified precisely, use the same names and effective date, and follow a stated order of precedence if terms conflict.

Model financing, exit, and maturity scenarios; approve debt and share issuance capacity; close funds and track accrued interest and note ownership.

• Confirm legal names, roles, capacity, addresses, and signing authority
• Reconcile dates, amounts, definitions, cross-references, schedules, and exhibits
• Confirm that duties, deadlines, approvals, acceptance standards, and payment triggers are measurable
• Check that default, termination, remedies, and surviving obligations work together
• Complete jurisdiction-specific forms, notices, witnesses, notarization, filings, or professional review when applicable
• Deliver and preserve the complete signed package with its incorporated documents
