Convertible Note Subscription Agreement Template for the United States

A Convertible Note Subscription Agreement is a specialized financing document that allows you to raise capital through debt that can later convert into company equity. Under United States law, this agreement must comply with federal securities regulations, including the Securities Act of 1933 and Securities Exchange Act of 1934, while also meeting state-specific Blue Sky law requirements that vary by jurisdiction.

When do you need this document?

You need this agreement when your startup requires bridge financing between equity rounds but cannot easily determine a fair company valuation. This document is essential for seed-stage companies seeking quick capital deployment, established startups preparing for Series A funding while maintaining operational runway, or companies pursuing strategic partnerships where conversion timing aligns with future milestones. The agreement is particularly valuable when traditional equity financing would create excessive dilution or when investors prefer debt instruments with equity upside potential.

Key legal considerations

Your agreement must carefully define conversion triggers, including qualified financing thresholds, automatic conversion events, and optional conversion rights at maturity. Critical terms include the conversion discount percentage, valuation cap provisions, interest rate structure, and maturity date obligations. You must address anti-dilution protections, pro rata participation rights, and information rights for note holders. The document should specify default remedies, acceleration clauses, and governing law provisions. Pay special attention to most favored nation clauses, which ensure your investors receive terms at least as favorable as those offered to subsequent note investors, and conversion mechanics that clearly define how the debt transforms into preferred or common stock.

Legal requirements in United States

Under federal law, your convertible note offering must comply with Securities Act exemptions, typically relying on Section 4(a)(2) private placement rules or Regulation D safe harbors like Rule 506(b) or Rule 506(c). You must file Form D with the SEC within 15 days of the first sale and maintain proper investor accreditation verification. State Blue Sky laws require additional compliance, including potential notice filings, merit review, or registration exemptions that vary significantly by state. The Internal Revenue Code imposes Original Issue Discount rules under Section 1272, requiring imputed interest calculations, and Section 409A deferred compensation regulations may apply depending on conversion terms. Investment Company Act considerations arise if your company could be classified as an investment company, requiring careful structural analysis to avoid registration requirements.
