Change-in-Control Severance, 280G Exposure, and Retaining the Chief Scientific Officer

The arithmetic

With a three-times base amount of $3.3M, the five-year average annualized includible compensation (the "base amount") is about $1.1M. Total parachute payments of $9.8M exceed three times the base amount, so the safe harbor is blown and the 20% excise tax applies to the excess over one times the base amount: $9.8M − $1.1M ≈ $8.7M excess, or roughly $1.74M of excise tax. The corporation also loses the deduction on that excess, worth roughly $1.8M at a 21% rate. Any gross-up itself is an additional parachute payment, so grossing up compounds the number.

Route 1: keep the gross-up. Clean for the executives, expensive for shareholders, and a live proxy-advisor target. It also removes any incentive for the executives to negotiate down.

Route 2: best-net cutback. The executive receives whichever is higher after tax: the full amount less excise, or a reduced amount capped at 2.99x. Cheapest for the company, but it unilaterally changes a contractual entitlement and, in a retention-sensitive deal, invites departures at exactly the wrong moment. Requires consent.

Route 3: clearing vote. Under the 280G regulations, payments approved by more than 75% of disinterested shareholders, after adequate disclosure of all material facts and the computation, are exempt. It must occur before any payment is made and must cover the specific payments. Two practical constraints here: the CSO's 3.2% holding is not a disinterested share, which shrinks both numerator and denominator and makes 75% harder; and the vote needs a proxy supplement, so the acquirer must hold the closing date.

Route 4: reduce the parachute itself. Deferring or converting equity acceleration, or conditioning part of the value on post-closing service, reduces the $9.8M directly. This is the only route that fixes both the tax and the retention problem, and it should be pursued alongside a clearing vote rather than instead of one.

The core problem

Full acceleration at closing destroys the retention hook: the CSO's $6.4M vests whether she stays or leaves. Any structure must convert already-vested value into value that is earned over time, without giving her a reason to walk before closing.

Recommended structure

1. Partial acceleration waiver. Negotiate a waiver in which a defined slice of the unvested equity (say $2.0–2.5M of value) is forfeited at closing in exchange for acquirer RSUs that vest 50% at 12 months and 50% at 24 months, subject to continued service. This reduces the parachute payment dollar-for-dollar, helps the 280G position, and restores the retention lever at no incremental cash cost to the acquirer beyond what it would have paid for the equity anyway.
2. Cash retention award paid by the acquirer at 12 months, sized to the value sacrificed, with forfeiture on voluntary resignation and clawback for cause. Paying at 12 months rather than at closing is essential: a payment contingent on the closing is a parachute payment; a payment contingent on post-closing service generally is not.
3. Severance preservation. Confirm whether the legacy CIC agreement survives the closing and whether "good reason" is triggered by the change in reporting line. Ambiguity here is what causes departures.

Consequences to model

• 280G. The waiver reduces the $9.8M and may bring the total closer to the safe harbor, but do not assume it eliminates the excise; re-run the calculation with the final terms. Confirm with counsel whether any acquirer-funded amounts are treated as parachute payments.
• 409A. Use the separation-pay exemption where available; otherwise apply release timing rules and the six-month delay for specified employees on any deferred component.
• Accounting. Acceleration of target equity at closing is generally treated as part of the acquisition consideration, while new acquirer retention awards are post-combination compensation expense recognized over the service period. The acquirer's finance team must see both.
• Governance. The CSO's 3.2% stake disqualifies her shares from the disinterested count in any clearing vote; sequence the waiver negotiation around that.

280G treatment

Assume it is a parachute payment. A bonus payable at closing for deal execution is contingent on the change in control, which is the defining test. The narrow "reasonable compensation for services rendered on or before the change in control" exclusion is unreliable here because the payment is triggered by the closing itself. So the $750K must be folded into the total parachute calculation and tested against the three-times safe harbor; if the deal is already over the threshold, this bonus increases the excess by $750K, adds $150K of excise, and removes the corresponding deduction unless a gross-up covers it.

Governance

The compensation committee, not management, must approve it, in a meeting with minutes stating the services, the amount, and the benchmarking or rationale. Transaction bonuses to named executive officers that appear late in a deal and are approved by the CEO are a classic proxy-advisor criticism. Confirm the acquirer is paying it and that the obligation is documented in the deal agreements rather than in a side letter, and check whether any pre-existing employment agreement already covers transaction-related compensation, which would make this a duplication.

Disclosure

The payment must appear in the golden parachute compensation table required in the merger proxy, and the merger proxy must include the separate advisory say-on-golden-parachute vote. If the agreement is amended after the proxy is filed, a supplement is required.

Recommendation

Do not approve it as a closing payment. Convert it to a retention award paid 12 months post-close with clawback, conditioned on the CFO supporting integration and financial reporting through the transition. That removes it from the parachute calculation, ties it to a real business need, and is defensible in the table.
