RE: William Brian Derge v. D&H United Fueling Solutions, Inc., et al., C.A. No. 2025-0087-BWD

Dear Counsel:

D&H United Fueling Solutions, Inc. (“D&H”) acquired TN Holdings, Inc.

(“TN Holdings,” and with D&H, “Defendants”) and TN Holdings’ subsidiary, Tanknology, Inc. (“Tanknology”), in a merger. As part of the sale, D&H required Tanknology’s top executives, including its Chief Operating Officer (“COO”), William Brian Derge (“Plaintiff”), to sign restrictive covenant agreements at closing. Plaintiff received nearly $1 million in consideration in exchange for his stock in the merger.

Approximately eighteen months later, Plaintiff filed suit seeking a declaration that the non-compete provision in his restrictive covenant agreement is “void and unenforceable as a matter of law.” The parties have cross-moved for

C.A. No. 2025-0087-BWD December 8, 2025 Page 2 of 21

summary judgment on that issue. For reasons explained below, the Court concludes that the non-compete is enforceable. I. BACKGROUND

A. D&H Acquires TN Holdings And Plaintiff Signs A Restrictive Covenant Agreement Containing A Non-Compete.

TN Holdings, a Delaware corporation, is a holding company with its principal place of business in Austin, Texas. Verified Compl. for Declaratory Relief [hereinafter Compl.] ¶¶ 2, 6, Dkt. 1; Answer to Verified Compl. for Declaratory Relief [hereinafter Answer] ¶¶ 2, 6, Dkt. 4. TN Holdings owns Tanknology, a Delaware corporation that provides tank testing and environmental compliance services for petroleum systems in the United States and internationally. Compl. ¶¶ 9–10; Answer ¶¶ 9–10; Unsworn Decl. of Tracy Long [hereinafter Long Decl.] ¶ 4, Dkt. 8.1

1 The Court has considered a declaration submitted by Tracy Long, the Chief Executive Officer of D&H, despite Plaintiff’s arguments that the Court should disregard the declaration because it was not submitted in the form of a sworn affidavit. See 10 Del. C. § 5354(a) (“Except as otherwise provided in subsection (b) of this section, if a law of this State requires or permits use of a sworn declaration, an unsworn declaration meeting the requirements of this chapter has the same effect as a sworn declaration.”); 10 Del. C. § 5356 (“An unsworn declaration under this chapter must be in substantially the following form[.]”); Long Decl. at 1 (complying with form under Section 5356 by “declar[ing] under penalty of perjury under the laws of Delaware that the following is true and correct”).

C.A. No. 2025-0087-BWD December 8, 2025 Page 3 of 21

Plaintiff served as Tanknology’s COO from June 2015 to July 31, 2024.

Compl. ¶ 2; Answer ¶ 2; Long Decl. ¶ 5. In that role, Plaintiff “managed all aspects of the domestic US storage tank compliance business lines” and “negotiated and managed vendor and supplier relationships”—responsibilities that, according to Defendants, made him “a key executive of Tanknology.” Compl. ¶ 13; Long Decl. ¶¶ 5–6; see also Aff. of Yury Kapko [hereinafter Yury Aff.] ¶ 6, Dkt. 14. Plaintiff also owned 200 shares of Class A common stock and 200 shares of Class B common stock of TN Holdings. Long Decl. ¶ 8. Plaintiff’s shares “were non-transferable, were only vested upon sale, and [were] contingent upon employment at the time of the sale.” Second Aff. of William Brian Derge [hereinafter Derge Aff.] ¶ 5, Dkt. 12.

On June 30, 2023, D&H acquired TN Holdings in a merger (the “Merger”)

pursuant to an Agreement and Plan of Merger (the “Merger Agreement”). Long Decl., Ex. A [hereinafter Merger Agt.] at 1; Compl. ¶ 2; Answer ¶ 2. Though Plaintiff’s shares represented just 0.73% of TN Holdings’ Class A common stock, Plaintiff executed a written consent approving the Merger. Derge Aff. ¶ 5; Merger Agt., Ex. L.2 In exchange for his shares in the Merger, Plaintiff received

The Merger Agreement stated that,

pursuant to which such Persons agree to certain restrictive covenants pursuant to the terms and conditions set forth therein.

Merger Agt. at 1. Exhibit B listed seven entities or individuals, including Plaintiff. Id., Ex. B. Section 3.1 of the Merger Agreement required TN Holdings to “deliver or cause to be executed and/or delivered” the Restrictive Covenant Agreements “[a]t the [June 30, 2023] Closing.” Id. § 3.1.

The same day the Merger Agreement was executed, Plaintiff and D&H entered into a Restrictive Covenant Agreement governed by Delaware law (the “Agreement”).4 Merger Agt. at 1; id., Ex. B.; Pl. William Brian Derge’s Mot. for Summ. J. [hereinafter Pl.’s Mot.], Ex. 1 [hereinafter Agt.] § 9(b), Dkt. 5. The
