TL;DR

One-way indemnity (operator indemnifies sponsor) is the sponsor MSA default; mutual indemnity (each party indemnifies for its own acts) is achievable for operators with negotiation leverage. Mutual indemnity materially reduces operator-side exposure on sponsor-caused issues like provided materials, sponsor-directed processes, and IP infringement claims tied to sponsor IP. The negotiation succeeds about half the time at the broker level.

MSA indemnity comparison

Mutual vs one-way indemnity. One sentence shifts millions in exposure.

The indemnity section of a sponsor MSA is where actual financial exposure gets allocated between the parties. It is also where insurance funding adequacy is determined. A mutual indemnity allocates losses to the party that caused them. A one-way indemnity puts every loss on the operator regardless of cause. Both are common; the difference matters at every claim.

Side-by-side

Nine dimensions of the indemnity decision.

Dimension

Mutual Indemnity

One-Way Indemnity (operator → sponsor)

Definition

Each party indemnifies the other for losses arising from its own acts, omissions, or breach.

Operator (CDMO/CRO/supplier) indemnifies sponsor; sponsor has no reciprocal obligation.

Industry baseline

Standard in negotiated MSAs between sophisticated parties, generic-pharma sponsor MSAs, and most CRO arrangements.

Default in innovator-pharma sponsor MSAs (especially branded biologics, oncology), most hospital purchase contracts, and many GPO supplier agreements.

Operator exposure

Limited to losses caused by operator acts; sponsor-caused losses fall on the sponsor.

Operator funds defense and indemnity even for losses partially or fully attributable to sponsor acts (sponsor protocol error, sponsor-supplied API defect, etc.).

Carveouts that matter

Gross negligence and willful misconduct typically carve out of indemnity caps on both sides.

Sponsor often agrees to carve out cases of sponsor gross negligence even within a one-way structure - important to verify.

Insurance funding fit

Operator's CGL/products tower funds operator's indemnity obligation; sponsor's policies fund sponsor's.

Operator's CGL/products tower funds the entire indemnity obligation, including for losses caused by sponsor - meaningful insurance leakage.

Caps

Caps typically aligned to insurance limits on each side. Each side carries its own program.

Caps often pushed higher or removed by sponsor counsel; operator pushback is the main negotiation.

Negotiability

Often the negotiated outcome from a sponsor-default one-way; operators with leverage typically achieve at least limited mutuality on sponsor gross negligence or sponsor-provided materials.

Sponsor default. Negotiating to mutual is achievable in many cases for non-branded sponsors; rarely achievable for branded innovator sponsors at the top of the market.

When operator should accept one-way

N/A - applies only to one-way structures.

When the engagement is strategically important, the indemnity is capped at insurance limits, sponsor carves out its own gross negligence, and operator's products tower is right-sized.

When operator should walk

N/A - applies only to one-way structures.

Uncapped one-way indemnity coupled with limits demands the operator cannot sustain commercially - particularly first-time engagements with marginal sponsors.

Frequently asked

Common questions about mutual vs one-way indemnity

What is the difference between mutual and one-way indemnity?

Mutual indemnity means each party indemnifies the other for losses caused by its own acts. One-way indemnity means the operator (CDMO/CRO/supplier) indemnifies the sponsor regardless of cause - including for losses caused by sponsor acts. The distinction matters at every claim.

Why do innovator pharma sponsors prefer one-way indemnity?

Sponsors use one-way indemnity as a risk-shifting mechanism that aligns the operator's incentive to maintain quality, manage inventory carefully, and bear the financial weight of any failure. From the sponsor perspective, the operator is closer to the manufacturing or service-execution risk and should bear it. Operators in the strongest market positions sometimes negotiate to mutual; most accept one-way for branded innovator engagements.

How do I negotiate from one-way toward mutual indemnity?

Operators with leverage typically achieve one or more of: (1) mutual indemnity for sponsor gross negligence and willful misconduct, (2) carveout from operator indemnity for losses caused by sponsor-provided materials (API, protocol, packaging components), (3) mutual indemnity capped at insurance limits, (4) full mutual indemnity in cases where the sponsor relies on the operator's clinical-stage status or strategic value. The leverage usually comes from claims history, sponsor relationship depth, or limited operator alternatives in the relevant product class.

Does my CGL/products policy cover one-way indemnity?

Generally yes for sponsor losses caused by your products or operations - that is exactly what products liability covers. But not for losses caused by sponsor acts that you have contractually agreed to indemnify under a one-way structure. The policy will cover indemnity obligations to the extent the underlying loss is covered; it will not turn the policy into a sponsor-protection vehicle.

Should indemnity always be capped at insurance limits?

Capping indemnity at insurance limits aligns operator financial exposure with operator insurance funding. Most well-counseled operators try to achieve this, with carveouts for gross negligence and willful misconduct on both sides. Whether you can achieve a cap depends on sponsor leverage; branded innovator sponsors push back, generic and many specialty sponsors accept it.
