Subscription Agreement: The Investment Contract Behind Every Private Placement

The PPM tells the story. The subscription agreement closes the deal. Here's what it must include.

Every private placement has two essential documents. The private placement memorandum provides disclosure - it tells the investor what they're buying and what could go wrong. The subscription agreement is the binding contract - it's how the investor actually commits capital and the company accepts the investment.

If the PPM is the informational foundation, the subscription agreement is the legal infrastructure. It captures the investor's representations (including accredited investor status), establishes the investment terms, and creates the compliance record that protects the company under Regulation D.

What a Subscription Agreement Must Include

1. Subscription Terms

The number of securities being purchased, the price per unit, the total investment amount, and the payment method and timing. For priced rounds, this is straightforward. For SAFE or convertible note rounds, the terms reference the separate instrument.

2. Investor Representations and Warranties

The most critical section from a securities compliance perspective. The investor represents that they are accredited (specifying the basis), that they are purchasing for investment and not resale, that they can bear the economic risk of total loss, and that they have reviewed the PPM and related documents. These representations form the foundation of the company's Regulation D compliance defense.

3. Accredited Investor Certification

A detailed questionnaire where the investor certifies the specific basis for their accredited status - income threshold, net worth threshold, professional certification, or entity qualification. For Rule 506(c) offerings, this self-certification is supplemented with documentary verification.

4. Risk Acknowledgments

The investor acknowledges specific risks: the securities are restricted and cannot be freely resold, there is no public market for the securities, the investment may result in a complete loss, and the company's projections may not be achieved. These acknowledgments reinforce the PPM disclosures and create a documented record.

5. Transfer Restrictions

Private placement securities are "restricted securities" under Rule 144. The subscription agreement must explain that the investor cannot resell without SEC registration or an applicable exemption, and that the securities will bear a restrictive legend. Typical holding period: 6-12 months minimum under Rule 144.

6. Company Acceptance

The subscription is an offer by the investor. The company must affirmatively accept it. This acceptance mechanism allows the company to reject investors who don't meet eligibility criteria or who raise compliance concerns. The subscription is not binding until accepted.

7. Governing Law and Dispute Resolution

Choice of law, venue for disputes, and whether arbitration is required. These provisions should be consistent across all offering documents - PPM, subscription agreement, operating agreement, and side letters.

How the Subscription Agreement Fits the Document Stack

PPM provides the disclosure → Investor reads and evaluates

Subscription Agreement captures the commitment → Investor signs and funds

Investor Questionnaire verifies eligibility → Company confirms accredited status

Operating Agreement / Bylaws governs the entity → Investor becomes a member/shareholder

Investor Rights Agreement establishes ongoing rights → Information rights, anti-dilution, board representation

The Consistency Imperative

Every document in the stack must be consistent. If the PPM says investors receive Class A preferred units and the subscription agreement says Class B, you have a securities fraud problem. If the operating agreement allows distributions at the manager's discretion but the PPM promises quarterly distributions, you have a disclosure problem. This is why the entire document stack should be prepared by the same attorney. At Acquisition Stars, Alex prepares the full package as an integrated unit.

Common Subscription Agreement Mistakes

Weak Investor Representations

A simple checkbox saying "I am an accredited investor" without specifying the basis is insufficient for compliance documentation. The subscription agreement should capture which accredited investor category applies and the specific qualifying information.

Missing Acceptance Mechanism

Without a formal acceptance process, the company can't reject unqualified investors. The subscription agreement should include a signature line for company acceptance and language stating the subscription is not binding until accepted.

No Integration Clause

Without an integration clause specifying that the subscription agreement and PPM constitute the entire agreement, investors can claim they relied on verbal promises or other communications. This is the "I thought you said..." problem.

Using Templates for Complex Offerings

A template subscription agreement for a simple equity offering won't work for a fund with waterfall distributions, carried interest, and multiple classes. The subscription agreement must mirror the actual economic terms of your specific offering.

Your Offering Documents Are Only as Strong as Their Weakest Link

The subscription agreement is the contract that binds your investors. The PPM is the disclosure that protects you. Together, they form the foundation of your capital raise.
