The yield maintenance clause on the senior is the mezz lender's problem, not the sponsor's.

The assumption doing the most work in your framing is that the mezz lender had access to a clean senior prepayment schedule before committing. In practice, the senior term sheet often arrives with a generalized yield maintenance formula rather than a year-by-year prepayment cost table, and mezz lenders close on that ambiguity rather than push for a modeled breakout. The result is exactly what you describe: exit fee structures priced against an assumed hold, not against a residual-after-prepayment-cost scenario at year two or three.

The net-proceeds carve-out you are asking about does exist in certain structures, but I have seen it more often framed as a waterfall mechanic than as explicit exit fee language in the mezz term sheet itself. The distinction matters because a waterfall mechanic still lets the sponsor argue about what counts as a senior prepayment cost and when it gets deducted, whereas a term-sheet provision that ties the exit fee floor to net proceeds after documented senior prepayment obligations is harder to litigate. The intercreditor rarely touches this because both lenders treat it as a waterfall problem and neither wants to be the one who caps their own return.

The risk you did not name is that a sponsor who maps this conflict early has an incentive to structure the exit timing around it rather than disclosing it, sitting in year four rather than year three to get past the steepest part of the yield maintenance curve, which shifts holding costs back onto the equity and compresses the mezz return indirectly through a longer carry period.

Confirm with your counsel how intercreditor agreements in your specific structures currently handle senior prepayment cost priority relative to mezz exit fees, because the standard language varies and this is a legal drafting question.

Have you seen deals where the sponsor disclosed the prepayment curve to the mezz lender during diligence, and if so, did that disclosure actually change how the exit fee was structured?

The distinction you are drawing is a real one that does not come up enough. The mezz lender models its return against a coupon and an exit fee, but the senior's prepayment cost sits upstream of that calculation and can eat the proceeds before the waterfall even starts. The two schedules compound: year three might carry the highest prepayment penalty on the senior at the same moment the sponsor has the strongest incentive to sell.

To put numbers on it at a small scale: imagine a $10M senior with a 2% yield maintenance fee and a $2M mezz with a $60,000 exit fee baked into the term sheet. If sale proceeds net $12.5M after closing costs, senior repayment plus the $200,000 prepayment fee takes $10.2M. That leaves $2.3M for the mezz and equity. The mezz gets its $2M principal back and, in a thin deal, the $60,000 exit fee may or may not clear depending on what the equity is owed first. The mezz lender underwrote against a clean exit; it did not model this scenario.

To your direct question: I have not seen a mezz term sheet that explicitly nets its exit fee against senior prepayment costs. From what I understand of how these get documented, that linkage almost always lands in the waterfall rather than the mezz documents themselves, and as you note, the intercreditor does not close the gap.

I would want to confirm with a real estate attorney whether there is any standard intercreditor language emerging on this point, because my read of current practice could be behind.

What is the deal type where you have seen this squeeze most? Construction refinances, or stabilized commercial?

The framing is right that the senior's prepayment schedule controls the timing optionality, but I would push it one step further: the mezz lender's real exposure is not just the squeeze on exit proceeds, it is that a punishing yield maintenance curve on the senior effectively extends the mezz hold whether the mezz documents say so or not. A sponsor who would otherwise sell in year three looks at 200k in prepayment cost and waits, which means the mezz lender's capital stays deployed at a coupon that was priced for three years of risk but now runs to five. On the term sheet question, the cleaner structure ties the exit fee to net proceeds after senior debt service costs including prepayment, which converts the mezz exit fee from a fixed obligation into something closer to a participation in residual equity, and some lenders resist that because it muddies the credit instrument with equity-like downside. The version that actually trades is a tiered exit fee that steps down in the same years the senior's prepayment penalty steps down, so the two schedules at least move in the same direction even if they are not explicitly linked. What does the senior's prepayment schedule look like year by year, because the conflict is usually worst when the senior uses a flat percentage rather than a declining step?
