How to use this toolkit

Each tool is a starting point calibrated to a position. Where three variants appear — Buyer, Seller, Middle — the middle version is where most negotiated deals land, and it is the right first draft when you represent either side and want to look reasonable.

The doctrinal background is in the companion article; the case law that most affects these provisions is Chicago Bridge & Iron Co. N.V. v. Westinghouse Electric Co., 166 A.3d 912 (Del. 2017) on the scope of a true-up, Airborne Health, Inc. v. Squid Soap, LP, 984 A.2d 126 (Del. Ch. 2009) and Winshall v. Viacom International, Inc., 76 A.3d 808 (Del. 2013) on the implied covenant in earnouts, and Bloor v. Falstaff Brewing Corp., 601 F.2d 609 (2d Cir. 1979) on what an efforts obligation actually requires.

Tool 1: Defining the Business

Middle position.

"Business" means the products and services set forth on Schedule 2.7(a) (identified by SKU, product family, and, where applicable, customer contract), together with any successor, derivative, replacement, upgraded, or improved version of any such product or service, in each case regardless of the legal entity, division, business unit, brand, or sales channel through which such product or service is developed, marketed, sold, licensed, or delivered.

Revenue Attribution. Revenue shall be attributed to the Business on the basis of the product or service sold, licensed, or delivered, and not on the basis of the entity, division, or sales organization recording the sale. Where a Business product or service is sold as part of a bundle or a multi-element arrangement, revenue shall be allocated to the Business in proportion to the standalone list price of the Business elements relative to the aggregate standalone list prices of all elements.

Why this matters more than anything else in the provision. Post-integration, entities merge and business units are reorganized. Product SKUs and customer contracts persist. A definition anchored to organizational structure evaporates; a definition anchored to products survives.

Buyer's fair objection, and the answer: the buyer will say that a product-based definition captures revenue generated entirely by the buyer's own sales force and distribution. The answer is a negotiated attribution haircut — for example, revenue from products sold through channels the buyer contributed is attributed at eighty percent — rather than an entity-based definition.

Tool 2: The metric definition

2.1 Revenue-based (seller-favorable, lowest dispute risk)

"Business Revenue" means, for any Earnout Year, the aggregate gross revenue attributable to the Business, determined in accordance with the Accounting Principles, less returns, allowances, and customer credits actually granted, and without deduction for any cost of goods sold, operating expense, corporate allocation, or other charge of any kind.

2.2 EBITDA-based (buyer-favorable, highest dispute risk)

"Business EBITDA" means, for any Earnout Year, Business Revenue less cost of goods sold and operating expenses of the Business, determined in accordance with the Accounting Principles, in each case computed before interest, taxes, depreciation, and amortization, and excluding:

(a) all expenses arising from or relating to the Transaction, including transaction expenses, retention and transaction bonuses, and the employer portion of payroll taxes thereon; (b) all effects of purchase accounting, including any step-up in the basis of assets and any amortization of intangibles recognized in the Transaction; (c) any impairment of goodwill or intangible assets recognized in the Transaction; (d) non-cash equity or equity-based compensation expense; (e) any management, monitoring, advisory, or similar fee charged by Buyer or any of its Affiliates; (f) any restructuring, severance, integration, or reorganization charge arising from a decision of Buyer; (g) any expense arising from a change in accounting policy not permitted by Section [hierarchy]; (h) any litigation expense or loss relating to a matter arising prior to the Closing; and (i) any allocation of corporate, shared, or indirect costs except as permitted by Section 2.3.

2.3 The overhead allocation cap — the provision that decides EBITDA earnouts

Allocation Cap. Allocations of corporate, shared, or indirect costs of Buyer and its Affiliates to the Business shall not exceed $[______] in the first Earnout Year, escalating by three percent (3%) in each subsequent Earnout Year (the "Allocation Cap"), and shall in all events exclude: (a) costs of Buyer's corporate development, investor relations, treasury, tax, and internal audit functions; (b) costs of any acquisition, disposition, financing, or capital markets transaction of Buyer other than the Transaction; (c) costs of any Buyer-wide information systems implementation, migration, or upgrade; (d) costs of Buyer's executive compensation above the level of the general manager of the Business; and (e) any allocation not consistent in kind and methodology with the allocation reflected in the Sample Calculation.

Note. Without this provision, an EBITDA earnout can be reduced to zero by allocations that are individually defensible, collectively enormous, and entirely within the buyer's discretion.

2.4 Intercompany transfer price

Sales of Business products or services by the Business to Buyer or any of its Affiliates shall be recorded at [the standard list price then in effect / the price charged to comparable unaffiliated third parties / the price set forth on Schedule 2.7(c)], and sales by Buyer or its Affiliates of Business products or services to third parties shall be attributed to the Business at [the third-party price / the third-party price less a distribution allowance of __%].

2.5 Binary milestone (life sciences and regulated industries)

"Approval Milestone" means the receipt by Buyer or any of its Affiliates of [marketing approval from the United States Food and Drug Administration of a New Drug Application for [Compound] for the treatment of [Indication]], on or before [date].

Diligence Obligations. Until the earlier of the achievement of the Approval Milestone and [date], Buyer shall: (a) conduct and complete the [Phase III] clinical trial described on Schedule [] in accordance with the protocol attached thereto; (b) expend not less than $[____] in the aggregate on development of [Compound]; (c) submit the [NDA] not later than [date] following availability of topline data; and (d) respond to regulatory inquiries within the periods customary for such submissions.

Abandonment. If Buyer discontinues development of [Compound], fails to satisfy any Diligence Obligation, or fails to submit the [NDA] by the date specified, then at the election of the Seller Representative either (i) the Milestone Payment shall become immediately due and payable or (ii) all rights in [Compound] shall revert to the Sellers at no cost.

Tool 3: Sample calculation exhibit — structure

Prepare using the target's most recent full fiscal year and actual trial balance. This is the highest-value hour in the negotiation.

Exhibit structure.

Anti-restatement covenant to accompany it:

The Earnout Statement shall be prepared applying the same accounting principles, policies, practices, methodologies, elections, judgments, estimation techniques, and classifications used in the preparation of the Sample Calculation, consistently applied. No change in any reserve, accrual, estimate, or judgment shall be reflected in the Earnout Statement except to the extent the underlying facts and circumstances have changed, and no principle, policy, practice, methodology, election, or classification shall be applied that was not applied in the Sample Calculation. In the event of any conflict between the Sample Calculation and GAAP, the Sample Calculation shall control.

Tool 4: Accounting principles hierarchy

"Accounting Principles" means, in the following order of precedence: first, the specific accounting policies, methodologies, elections, and classifications set forth on Schedule [__] and reflected in the Sample Calculation; second, to the extent not addressed in clause first, the accounting principles, practices, methodologies, policies, and classifications used in the preparation of the Audited Financial Statements for the fiscal year ended [date], applied on a basis consistent therewith; and third, to the extent not addressed in clauses first or second, GAAP.

Companion sentence for the working capital adjustment:

The purpose of Section [true-up] is solely to measure changes in Net Working Capital, Cash, Indebtedness, and Transaction Expenses between the Reference Date and the Closing, computed on a consistent basis. Section [true-up] is not intended to, and shall not be used to, adjust the Purchase Price for any change in accounting methodology, policy, practice, or judgment, or to address any matter that is the subject of any representation or warranty, and no such matter shall be the basis of any adjustment hereunder.

This is the express version of the reading the Delaware Supreme Court gave in Chicago Bridge. Do not rely on a court to reach it; write it.

Tool 5: Operating covenant schedule

Section [__]. Conduct of the Business During the Earnout Period. From the Closing until the end of the last Earnout Year, Buyer shall, and shall cause its Affiliates to:

(a) Separate records. Maintain the Business as a separate reporting unit with books and records sufficient to compute the Earnout Metric in accordance with the Accounting Principles and the Sample Calculation.

(b) Sales organization. Maintain not fewer than [__] quota-carrying sales representatives whose primary responsibility is the sale of Business products, with quotas and incentive compensation no less favorable, relative to product margin, than those applicable to Buyer's comparable products.

(c) Marketing spend. Expend on the marketing and promotion of Business products not less than []% of Business Revenue in each Earnout Year, or $[____], whichever is greater.

(d) Product continuity. Not discontinue, sunset, end-of-life, or cease providing commercially reasonable support or maintenance for any product listed on Schedule 2.7(a) without the prior written consent of the Seller Representative.

(e) Pricing. Not reduce the list price of any Business product by more than [__]% from the price in effect at Closing without prior consultation with the Seller Representative.

(f) Accounts. Not reassign any customer account listed on Schedule [__] away from the Business sales organization, and not transfer, novate, or migrate any Business customer contract to a non-Business product.

(g) Channel parity. Afford Business products treatment no less favorable than comparable Buyer products in Buyer's distribution channels, partner programs, incentive compensation plans, marketing programs, and product roadmaps.

(h) Accounting policy. Not change any revenue recognition policy, reserve methodology, or capitalization policy applicable to the Earnout Metric.

(i) Key employees. Not terminate the employment of any individual listed on Schedule [__] other than for Cause, and not materially diminish the duties, authority, or compensation of any such individual.

(j) Capital. Fund the Business's working capital and capital expenditure requirements consistent with the budget attached as Schedule [], subject to variance of not more than []%.

(k) Backstop. Not take, and not permit any Affiliate to take, any action that would reasonably be expected to reduce the Earnout Metric, other than actions taken in the ordinary course of business consistent with the past practice of the Business, whether or not such action is intended to reduce any Earnout Payment.

Buyer's paired provision:

Section [__]. Buyer Discretion. Except as expressly provided in Section [operating covenants], Buyer shall have sole and absolute discretion with respect to the operation of the Business and its other businesses, shall have no obligation to operate the Business in any manner that maximizes any Earnout Payment, and may act in its own interest. The parties acknowledge that Buyer's obligations with respect to the Earnout are limited to those expressly set forth in this Agreement.

Note the interaction. The buyer discretion clause narrows the space in which an implied covenant argument can operate. The backstop covenant in (k) preserves the seller's protection against effects the covenants do not enumerate. Both belong in a well-negotiated agreement.

Tool 6: Acceleration, security, and set-off

Acceleration.

Upon the occurrence of any Acceleration Event, the maximum aggregate Earnout Payments not theretofore paid shall become immediately due and payable in cash within ten (10) Business Days, without regard to whether any Earnout Target has been or would have been achieved. "Acceleration Event" means: (a) a sale, transfer, exclusive license, or other disposition of all or substantially all of the Business or of assets generating more than []% of Business Revenue; (b) discontinuation of, or cessation of commercially reasonable support for, products representing more than []% of Business Revenue in the preceding twelve months; (c) a breach by Buyer of Section [operating covenants] that remains uncured for thirty (30) days following written notice from the Seller Representative; (d) any Change of Control of Buyer in which the acquiring party does not assume the obligations under this Article in writing; (e) termination without Cause, or resignation for Good Reason, of any individual listed on Schedule [__]; or (f) the commencement of any bankruptcy, insolvency, receivership, or similar proceeding by or against Buyer or the Business.

Parent guarantee.

Guarantor hereby irrevocably and unconditionally guarantees to the Sellers the full and punctual payment when due of all Earnout Payments and all other amounts payable by Buyer under Article [__]. This is a guarantee of payment and not of collection. Guarantor waives any requirement that the Sellers first proceed against Buyer, and waives all defenses other than payment in full. This guarantee shall survive any assignment, merger, or reorganization of Buyer.

Set-off — three variants.

Buyer. Buyer may set off against any Earnout Payment the amount of any claim for indemnification asserted by Buyer in good faith, whether or not resolved.

Seller. Buyer shall have no right of set-off against any Earnout Payment.

Middle. Buyer may set off against any Earnout Payment (i) the amount of any indemnification claim that has been finally determined in Buyer's favor, and (ii) the amount of any indemnification claim asserted in good faith and not finally determined, provided that any amount withheld under clause (ii) shall be deposited into an interest-bearing escrow account with the Escrow Agent and released in accordance with the final determination of such claim.

The middle version is the right first draft for either side. An unrestricted set-off is self-help that a seller can undo only by suing; a total prohibition leaves a buyer chasing distributed proceeds.

Tool 7: Working capital line-item schedule template

Prepare from the trial balance. Every account gets a designation.

Add below the table: the trailing twelve-month monthly computation used to derive the Target, on the same basis; the seasonality adjustment, if any; and the collar amount identified as a deductible or a threshold.

Tool 8: Access request letter

[Date] — By email and overnight courier

Re: [Agreement], Section [__] — Access Request Following Delivery of the [Earnout / Closing] Statement

We received the Statement dated []. Pursuant to Section [], the Seller Representative requests the following, and notes that under Section [__] the Review Period does not commence until such access has been provided:

1. The general ledger detail for the Business for the period, in native electronic format with account descriptions.
2. Revenue detail at SKU level for the period, reconciled to the Statement.
3. All schedules supporting the allocation of corporate, shared, and indirect costs, including the cost pools, drivers, and computations, and a comparison to the allocation reflected in the Sample Calculation.
4. Buyer's consolidation entries affecting the Business for the period.
5. Intercompany pricing records for Business products.
6. Management reporting packages relating to the Business for each period.
7. Documentation supporting each exclusion applied under Section [__].
8. Records evidencing compliance with Section [operating covenants], including headcount by role and period, marketing spend by category, product status for each item on Schedule 2.7(a), and account assignment records for accounts listed on Schedule [__].
9. Availability of [names] for a working session during the week of [__].

Please confirm a production schedule within five (5) Business Days. We reserve all rights.

Tool 9: Objection notice form

NOTICE OF OBJECTION — [Agreement], Section [__]

Pursuant to Section [__], the Seller Representative objects to the [Earnout / Closing] Statement delivered [date]. The disputed items, the basis for each objection, and the Seller Representative's position are set forth below. The Seller Representative reserves the right to withdraw any objection and to supplement the basis for any objection as additional information is provided.

#	Line item	Buyer's amount	Seller Rep's amount	Difference	Basis
1	Corporate allocation	$	$	$	Exceeds Allocation Cap; includes excluded categories (c), (d)
2	Revenue — Business products sold through Buyer channel	$	$	$	Attribution follows product per Section []; omitted SKUs []
3	Restructuring charge	$	$	$	Buyer-driven; excluded under Section 2.2(f)
4	Inventory reserve	$	$	$	Methodology differs from Sample Calculation note 5
	Aggregate difference			$

Separately and without prejudice, the Seller Representative asserts that Buyer has breached Sections [] (sales headcount), [] (marketing spend), and [] (account reassignment). Such claims are expressly outside the jurisdiction of the Independent Accountant under Section [] and are asserted under Section [dispute resolution]. A separate notice follows.

Two drafting habits worth adopting. Object to every line with any basis — withdrawal is available later, addition is not. And separate the accounting objection from the breach claim in form as well as in substance, so the accountant's jurisdiction is never in doubt.

Tool 10: Independent accountant engagement letter — required terms

Draft this as an exhibit at signing so it is not negotiated during a dispute.

1. Appointment. [Firm] is engaged jointly by Buyer and the Seller Representative as the Independent Accountant under Section [__] of the Agreement.

2. Independence. The Firm confirms it has no current or prior engagement with Buyer, the Sellers, the Business, or their respective Affiliates within the past [three] years, other than as disclosed on Annex A.

3. Scope. The Firm shall determine only the items set forth in Annex B (the disputed items remaining after negotiation). The Firm shall not review, adjust, or opine on any other item, shall not determine any claim of breach of the Agreement, and shall not award damages.

4. Standard. The Firm shall apply the Accounting Principles as defined in the Agreement and the Sample Calculation attached as Annex C, and shall not apply its own view of preferable accounting practice.

5. Resolution. For each disputed item, the Firm shall select either Buyer's position or the Seller Representative's position and no other amount.

6. Procedure. Simultaneous written submissions of not more than [30] pages plus exhibits, due [date]; simultaneous responses of not more than [15] pages, due [date]; no oral hearing unless the Firm requests one; no ex parte communication of any kind; all communications copied to both parties.

7. Determination. Written determination with a brief statement of reasons for each item, delivered not later than [45] days after the response submissions. The determination is final and binding absent fraud or manifest error.

8. Status. The Firm acts as an expert and not as an arbitrator. [Or: as an arbitrator, and the determination may be confirmed under 9 U.S.C. § 9 and vacated only on the grounds set forth in 9 U.S.C. § 10.]

9. Fees. Allocated between the parties in proportion to the aggregate dollar amount of the disputed items determined against each.

Choose paragraph 8 deliberately. Expert determination is narrower and generally reviewable only for a departure from the submission; arbitrator status imports the Federal Arbitration Act framework. Agreements that leave this ambiguous generate a threshold fight about the standard of review before anyone reaches the merits.

Tool 11: Covenant compliance log

The buyer should maintain this quarterly. It is the document that resolves a covenant claim in a single letter.

Attach each quarter: the headcount report, the marketing spend detail by category, the product status list, and any account assignment changes with the business rationale.

Tool 12: Closing-day calendar

Tool 13: Seller representative provisions

Appointment. Each Seller irrevocably constitutes and appoints [Name] as the Seller Representative, as its true and lawful attorney-in-fact and agent, with full power of substitution, to act in the name, place, and stead of such Seller with respect to all matters arising under Article [__]. This appointment is coupled with an interest, is irrevocable, and shall survive the death, incapacity, dissolution, bankruptcy, or transfer of interest of any Seller.

Authority. The Seller Representative may: receive all notices and statements; review, dispute, negotiate, and settle any matter under Article [__]; deliver objection notices; engage accountants, counsel, and other advisors at the expense of the Sellers; execute any document; and take any action it deems necessary, and each Seller shall be bound by all such actions.

Expense Fund. At Closing, $[____] shall be withheld from the amounts otherwise payable to the Sellers and delivered to the Seller Representative as the Expense Fund. The Seller Representative may apply the Expense Fund to its fees and expenses and those of its advisors, and may replenish the Expense Fund from any Earnout Payment before distribution. Any remaining balance shall be distributed to the Sellers upon satisfaction of all obligations under Article [].

Exculpation and Indemnity. The Seller Representative shall have no liability to any Seller for any act or omission taken in its capacity as such, absent gross negligence or willful misconduct, and shall be indemnified by the Sellers, severally in proportion to their respective interests, against all losses arising from its service.

Attach the allocation spreadsheet at closing. Preferences, participation, option holders, escrow contributions, expense fund contributions, and the per-dollar distribution percentage for each holder. Allocation disputes among sellers are common, bitter, and entirely preventable by a spreadsheet everyone saw before signing.
