Introduction: The Hidden Risk in Sustainability-Linked Agreements

When a company signs a sustainability-linked loan or bond, it typically agrees to meet specific ESG targets—such as reducing carbon emissions or improving diversity metrics—in exchange for lower interest rates or other benefits. But what happens when the company is acquired, restructured, or files for bankruptcy? The waiver that granted those benefits may vanish, leaving the successor free to abandon the sustainability commitments. This is the stealth clause problem: the need for a sustainability-linked waiver to survive not just the current parties, but future generations of stakeholders. Based on our experience advising corporate clients, we find that most drafters focus only on the initial term, neglecting the long-term enforceability that makes these agreements truly impactful. This oversight can undermine the entire purpose of sustainability-linked finance.

In this guide, we unpack why long-term survival matters, what legal mechanisms are available, and how to draft clauses that endure. We will compare three main approaches, walk through a step-by-step drafting process, and answer common questions. Whether you are a lawyer, a CFO, or a sustainability officer, understanding the stealth clause is essential to ensuring that today's ESG commitments are not tomorrow's empty promises. The stakes are high: a waiver that dies with the original borrower can lead to greenwashing accusations, investor backlash, and regulatory scrutiny.

Why Standard Waivers Fail When Control Shifts

Standard sustainability-linked waivers are often drafted as personal covenants—they bind only the original parties. When a company is acquired, merged, or undergoes a change of control, the waiver typically terminates unless expressly assigned. In bankruptcy, the waiver may be rejected as an executory contract under Section 365 of the U.S. Bankruptcy Code. We have reviewed numerous agreements where the waiver language was simply: 'Lender agrees to waive compliance with ESG covenants for the 2024 fiscal year.' This is dangerously vague. It does not specify that the waiver runs with the loan or binds successors. Consequently, when control shifts, the new entity can disregard the waiver, and the sustainability-linked benefit disappears.

Another common failure point is the absence of anti-assignment provisions. Many contracts allow assignment of rights but not obligations, so the waiver (a right of the borrower) may be assignable while the underlying sustainability obligations are not. This asymmetry creates a loophole: the borrower can transfer the loan but avoid the ESG commitments. Practitioners often report that these issues are discovered only after a transaction, when it is too late to fix. The cost can be significant: a sustainability-linked discount that was supposed to last a decade may evaporate in the first year after an acquisition. To avoid this, drafters must treat the waiver as a property right that needs to be recorded and transferred with the underlying instrument.

Composite Scenario: Acquisition Gone Wrong

Consider a mid-sized manufacturing company that obtained a $200 million sustainability-linked loan in 2023, with a waiver reducing the interest rate by 0.5% for meeting emission targets. In 2025, the company is acquired by a private equity firm. The acquisition agreement is silent on the waiver. Post-closing, the new management decides to abandon the emission targets, claiming the waiver expired upon change of control. The lender argues otherwise, but the waiver language is ambiguous. The result: litigation, reputational damage, and the loss of a key sustainability initiative. This scenario illustrates why the stealth clause must be explicit about survival.

To prevent such outcomes, drafters should include a clause stating that the waiver is 'irrevocable, perpetual, and binding on all successors, assigns, and heirs.' However, even that may not be enough in bankruptcy, where courts can reject burdensome contracts. Additional protections, such as recording the waiver as a covenant running with the land (if tied to real estate) or embedding it in a separate agreement that survives termination, may be needed. The key is to anticipate the full range of control shifts and draft accordingly.

Legal Mechanisms for Durable Waivers

Creating a waiver that survives generations requires understanding several legal mechanisms. The first is the concept of a 'covenant running with the land' or a 'real covenant,' which attaches to property and binds all future owners. While most sustainability-linked waivers are not tied to real estate, they can be structured similarly by using a deed or a restrictive covenant that registers against the borrower's assets. This approach is common in conservation easements and could be adapted for ESG commitments. However, it requires the waiver to touch and concern the property, which may not always apply.

The second mechanism is the third-party beneficiary clause. By explicitly naming future lenders, investors, or even the public as intended beneficiaries, the waiver can be enforced by parties who were not originally signatories. This prevents a successor from unilaterally revoking the waiver. We recommend including a statement like: 'This waiver is for the benefit of the borrower, its successors, and all future holders of the loan.' Courts are more likely to enforce waivers that clearly express an intent to benefit third parties.

A third approach is the use of a 'waiver that survives termination' clause, often found in settlement agreements. This clause states that even if the underlying contract is terminated, the waiver remains in effect. For sustainability-linked waivers, this could be paired with a 'perpetual waiver' provision that does not expire. However, perpetual waivers are disfavored in some jurisdictions because they can be seen as unreasonable restraints on alienation. Drafters must balance durability with enforceability.

Comparison of Three Approaches

MechanismProsConsBest For
Covenant Running with the LandStrong property-rights protection; binds all future owners; recordableLimited to real estate context; requires property interest; may be subject to recording requirementsWaivers tied to physical assets (e.g., green buildings, land conservation)
Third-Party BeneficiaryBroad enforcement by multiple parties; flexible drafting; no property neededMay require express language; beneficiaries must be identifiable; can be limited by contract lawLoan agreements and bonds with multiple lenders or investors
Survival Clause + Perpetual WaiverStraightforward; survives termination; easy to draftMay be unenforceable as unreasonable restraint; jurisdiction-specific; can be challenged in bankruptcyStandalone waiver agreements; short-term waivers with long-term intent

Each mechanism has trade-offs. In practice, a combination often works best: a third-party beneficiary clause paired with a survival clause that explicitly states the waiver is 'irrevocable and perpetual, binding on all successors and assigns.' Additionally, registering the waiver with a central registry (e.g., a securities filing or land records) provides notice to future parties. We have seen clauses that fail simply because they were not recorded, allowing bona fide purchasers to claim ignorance. Therefore, recording is a critical step.

Drafting the Stealth Clause: Step-by-Step Guide

Drafting a stealth clause requires careful attention to language, scope, and enforceability. Below is a step-by-step guide based on best practices from sustainable finance practitioners. Step 1: Define the waiver scope. Specify exactly what is being waived—for example, compliance with specific ESG metrics or reporting requirements. Use clear, measurable terms to avoid ambiguity. For instance: 'Lender waives compliance with the emission reduction covenant set forth in Section 4.2 for the period January 1, 2026 through December 31, 2026.'

Step 2: Include a survival clause. State that the waiver survives termination of the underlying agreement, change of control, assignment, and bankruptcy. Use language like: 'This waiver shall survive any termination, assignment, or transfer of this agreement, and shall be binding upon the parties, their successors, assigns, and any trustee or receiver appointed in bankruptcy.' This ensures the waiver persists even if the original contract ends.

Step 3: Add third-party beneficiary language. Identify who can enforce the waiver. Consider including future lenders, investors, regulators, or even the public. For example: 'This waiver is for the benefit of the borrower, its successors, and all present and future holders of the loan. Each such holder is an intended third-party beneficiary of this waiver.' This gives standing to enforce.

Step 4: Record the waiver. If possible, file the waiver with a public registry, such as the county recorder's office (if tied to real estate) or as a securities filing (e.g., Form 8-K for material agreements). Recording provides constructive notice to all future parties, blocking claims of ignorance.

Step 5: Address bankruptcy. Include a clause that the waiver is not an executory contract and cannot be rejected under bankruptcy law. While courts may still review it, express language can influence the outcome. Example: 'The parties agree that this waiver is a release and not an executory contract, and it shall not be subject to rejection under Section 365 of the Bankruptcy Code.'

Step 6: Review jurisdiction-specific laws. Some states or countries restrict perpetual waivers or covenants running with the land. Consult local counsel to ensure enforceability. For instance, in the UK, a waiver may be considered a 'contractual waiver' that can be revoked unless it is a deed. In the US, the validity of perpetual waivers varies by state. Tailor the clause accordingly.

Step 7: Test the clause with hypothetical scenarios. Before finalizing, simulate a change of control, an assignment, and a bankruptcy. Does the waiver survive each scenario? If not, revise. This stress-testing can reveal gaps.

Step 8: Negotiate with counterparties. Some lenders may resist a perpetual waiver, arguing it limits their flexibility. Be prepared to compromise, perhaps by limiting the waiver to a fixed term (e.g., 50 years) or tying it to specific assets. The goal is to create a waiver that is durable but acceptable to all parties.

Example Clause Language

Here is a sample stealth clause for a sustainability-linked loan: 'This waiver is irrevocable and perpetual. It shall be binding upon the borrower, its successors, assigns, and all persons acquiring an interest in the loan. This waiver shall survive any termination, assignment, or transfer of the loan agreement, and any change of control of the borrower. Each present and future holder of the loan is an intended third-party beneficiary of this waiver. This waiver shall not be subject to rejection under any bankruptcy or insolvency law. The borrower shall record this waiver with the appropriate registry within 30 days of execution.' This language covers the key elements but should be adapted to specific facts and jurisdiction.

Common Challenges and How to Overcome Them

Even with a well-drafted stealth clause, challenges can arise. One frequent issue is lender resistance. Lenders may argue that a perpetual waiver restricts their ability to renegotiate terms or sell the loan. To address this, we suggest framing the waiver as a benefit to the lender: it enhances the loan's ESG credentials, making it more attractive to ESG-focused investors. Data from market surveys indicates that sustainability-linked loans with durable waivers often trade at a premium in secondary markets.

Another challenge is enforceability in bankruptcy. Despite careful drafting, a bankruptcy court may still reject the waiver if it is deemed an executory contract or if it impairs the debtor's fresh start. To mitigate this, consider including a clause that the waiver is a 'release' or 'covenant not to sue,' which are more likely to survive bankruptcy. Additionally, obtaining a separate escrow or security interest tied to the waiver can provide extra protection.

A third challenge is the lack of public recording. Many companies fail to record waivers, allowing successors to claim ignorance. The solution is to make recording a contractual obligation, with consequences for non-compliance. For example, the agreement could state that failure to record renders the waiver voidable at the lender's option, incentivizing recording.

Finally, cross-border issues can complicate enforceability. A waiver valid in one jurisdiction may not be recognized in another. For global loans, include a choice-of-law clause specifying a favorable jurisdiction (e.g., New York or England) and a dispute resolution mechanism. Also, consider obtaining local legal opinions in all relevant jurisdictions. By anticipating these challenges and building solutions into the contract, drafters can significantly increase the waiver's chances of survival.

Real-World Composite Scenarios

To illustrate the stealth clause in action, we present two composite scenarios drawn from common industry patterns. The first involves a renewable energy company that secured a sustainability-linked bond with a waiver for meeting biodiversity targets. The waiver was drafted with a third-party beneficiary clause and recorded as a covenant running with the land. When the company was acquired by a multinational, the acquirer's legal team reviewed the waiver and found it binding. The acquirer decided to continue the biodiversity program, partly because the waiver was enforceable. The result: the ESG commitments survived the acquisition intact.

The second scenario is a cautionary tale. A consumer goods company obtained a sustainability-linked loan with a waiver for reducing water usage. The waiver was a simple paragraph in the loan agreement, with no survival or third-party language. The company later filed for Chapter 11 bankruptcy. The bankruptcy trustee rejected the waiver as an executory contract, and the water reduction program was discontinued. The lender lost its ESG-linked discount, and the company faced criticism from environmental groups. This scenario underscores the cost of neglecting the stealth clause.

In both scenarios, the difference was the drafting approach. The first company invested time in creating a durable waiver, while the second relied on a standard form. The lesson: the stealth clause is not a minor detail but a critical component of any sustainability-linked agreement. By learning from these examples, practitioners can avoid common pitfalls and build waivers that last.

Frequently Asked Questions

Q: Can a sustainability-linked waiver be truly perpetual?
A: In many jurisdictions, perpetual waivers are enforceable if they are clear, reasonable, and not contrary to public policy. However, some courts may limit them under the rule against perpetuities or as unreasonable restraints on alienation. To mitigate, consider a fixed long term (e.g., 99 years) instead of perpetual, which is often accepted.

Q: What if the successor never agreed to the waiver?
A: If the waiver is drafted as a covenant running with the land or a third-party beneficiary clause, it binds successors even without their express agreement. The key is to give them notice through recording or explicit language in the original contract.

Q: Does the stealth clause work in all countries?
A: No. Enforcement depends on local contract law, property law, and bankruptcy regimes. For example, civil law countries may not recognize covenants running with the land in the same way as common law. Always consult local counsel.

Q: Can a lender revoke a durable waiver?
A: If the waiver is irrevocable by its terms, the lender cannot unilaterally revoke it. However, courts may allow revocation if there is fraud, mistake, or a material change in circumstances. Drafting an 'irrevocable' clause reduces this risk.

Q: How does the stealth clause affect loan pricing?
A: A durable waiver may increase the loan's value by ensuring ESG benefits persist, potentially lowering the interest rate. Conversely, lenders may demand a higher rate for waiving rights indefinitely. Negotiate based on the loan's risk profile.

Conclusion: Embedding Long-Term Commitment

The stealth clause is not a legal trick but a necessary tool for ensuring that sustainability-linked waivers fulfill their purpose over time. Without it, ESG commitments are fragile, vulnerable to the whims of future decision-makers. By incorporating survival clauses, third-party beneficiary protections, and recording mechanisms, drafters can create waivers that endure across generations of stakeholders. The effort required is modest compared to the cost of a failed waiver—lost discounts, reputational harm, and legal disputes.

As sustainability-linked finance grows, the ability to enforce commitments long-term will differentiate genuine ESG integration from greenwashing. Regulators and investors are increasingly scrutinizing these agreements, and durable waivers are a signal of good faith. We encourage all parties to review their existing waivers for stealth clause gaps and to adopt best practices in new agreements. The future of sustainable finance depends on commitments that last beyond the next transaction.
