MEMORANDUM OPINION AND ORDER
JERRY VENTERS, Bankruptcy Judge.
On May 6, 1999, the Chapter 11 Trustee, Mark G. Stingley, filed an adversary proceeding against AlliedSignal, Inc. ("AlliedSignal" or "Defendant"), seeking the avoidance and recovery of a purported preferential transfer from the Debtor, Libby International, Inc. ("Libby"), to AlliedSignal pursuant to 11 U.S.C. § 547. The matter comes before the Court at this juncture on competing motions for summary judgment.
In addition to the motions for summary judgment and suggestions filed in support thereof, the parties submitted a joint pretrial statement and a statement of stipulated facts. Based on the foregoing, the matter hinges on the single legal issue of whether the earmarking doctrine should be applied to $325,319.45 in transfers made from an escrow account to AlliedSignal within 90 days of the Debtor's bankruptcy filing. If the doctrine applies, the transfers would not be preferential; however, if it does not apply, the transfers would be preferential and therefore subject to avoidance and turnover pursuant to 11 U.S.C. §§ 547(b) and 542(a).
Upon consideration of the parties' submissions and the Court's independent research, the Court finds that the earmarking doctrine does not apply to the transfers in question. Therefore, the transfers will be avoided, and the Court will grant summary judgment for the Trustee,[1] and deny summary judgment for the Defendant, AlliedSignal.
*377 This action is a core proceeding pursuant to 28 U.S.C. § 157(b)(2)(F), and this Court has subject matter jurisdiction pursuant to 28 U.S.C. §§ 157(a) and 1334(b).
This Memorandum Opinion and Order constitutes the Court's findings of fact and conclusions of law as required by Rule 7052, Fed.R.Bankr.P. The Stipulation of Facts submitted by the parties is incorporated by reference herein and is attached hereto (without the supporting exhibits) as Attachment A.

DISCUSSION
Summary judgment is governed by Rule 56, Fed.R.Civ.P., which is made applicable to bankruptcy proceedings by Bankruptcy Rule 7056, Fed.R.Bankr.P. That rule provides, in pertinent part:
The judgment sought shall be rendered forthwith if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.
Rule 56(c), Fed.R.Civ.P.
The submissions of the parties indicate that there is no genuine issue of material fact; therefore, the Court will decide this matter on the basis of the motions for summary judgment and supporting documents.
The determinative question to be decided by the Court is whether the earmarking doctrine applies to the $325,319.45 in transfers made from the Escrow Account to AlliedSignal within the 90-day preference period.
The earmarking doctrine is a judicially created exception to 11 U.S.C. § 547 that derives from the statutory requirement that a transfer, in order to be deemed preferential, must be "of an interest of the debtor in property." Buckley v. Jeld-Wen, Inc. (In re Interior Wood Products Co.), 986 F.2d 228, 231 (8th Cir.1993); Lewis v. Providian Bancorp (In re Getman), 218 B.R. 490, 492 (Bankr.W.D.Mo. 1998). In addition to the five elements under § 547 (§ 547(b)(1)-(5)), a trustee must prove that the transfer in question was not subject to the earmarking doctrine, i.e., that the debtor did have an interest in the property transferred. The doctrine, as it is applied in the Eighth Circuit, has three basic requirements: "(1) the existence of an agreement between the new lender and the debtor that the new funds will be used to pay a specified antecedent debt; (2) performance of the agreement according to its terms; and (3) the transaction viewed as a whole (including the transfer of the new funds and the transfer out to the old creditor) does not result in any diminution of the estate." McCuskey v. National Bank of Waterloo (In re Bohlen Enterprises, Ltd.), 859 F.2d 561, 566 (8th Cir.1988). The first requirement has been expanded somewhat beyond this basic formulation to include existing lenders (as opposed to only "new" lenders) and to include transactions in which a debtor grants the "new" lender a security interest (of priority equal to the "old" creditor's) in the debtor's property. See Kaler v. Community First National Bank (In re Heitkamp), 137 F.3d 1087 (8th Cir. 1998) (hereinafter "Heitkamp"). However, the basic formulation of "new funds pursuant to an agreement, performance of the agreement, and no net diminution of the estate" remains intact. The Trustee has the burden of proving that the earmarking doctrine does not apply, In re Ward, 230 B.R. 115, 119 (8th Cir. BAP 1999). The Court finds that the Trustee has met this burden.
*378 The Trustee has clearly demonstrated that the earmarking doctrine does not apply to the transfers at issue because two of the three necessary elements of the earmarking doctrine are not present. First, the payments made by the Air Force into the Escrow Account were not new funds, but rather funds that were already owed to Libby pursuant to its contract with the Air Force. Put simply, they were accounts receivable. In a practical sense they might have been "earmarked," inasmuch as AlliedSignal and Libby had an agreement to channel those payments directly (via the Escrow Account) from the Air Force to AlliedSignal. But, because AlliedSignal failed to perfect its security interest in the Escrow Account outside of the preference period, the agreement cannot withstand avoidance as a preference; as an unsecured creditor, receipt of the Air Force's payments would enable AlliedSignal to recover more than it would have in a Chapter 7 liquidation. See 11 U.S.C. § 547(5)(A).
Furthermore, the "agreement" between AlliedSignal and Libby does not satisfy the earmarking doctrine's requirement that there be an agreement between the new lender and the debtor that the new funds will be used to pay a specified antecedent debt. The only agreement offered into evidence was an agreement between an old creditor, AlliedSignal, and the Debtor. The "agreement" that involved the Debtor and a "new lender" was Libby's request for a modification of the contract with the Air Force to change the remittance address for future payments, and this agreement is a far cry from one to pay an antecedent debt.
Second, there was a net diminution of the estateThe transfers to AlliedSignal reduced the amount of assets that would be available to general unsecured creditors of which AlliedSignal would only be entitled to its pro-rata share, and the application of the earmarking doctrine here would be equivalent to granting AlliedSignal a security interest in Libby's accounts receivable, which was exactly what AlliedSignal tried to obtain but failed.[2]
AlliedSignal has countered with a number of creative, but ultimately unavailing, arguments. First, AlliedSignal argues that the Eighth Circuit's decision in Heitkamp expanded the earmarking doctrine to apply to the present situation. This reading greatly overstates the extent Heitkamp alters the application of the earmarking doctrine. Heitkamp should be read as shifting the focus away from the identity and relationship of the party supplying the new funds and towards the net effect or result of the transfers. See In re Ward, 230 B.R. at 118-120 ("Heitkamp represents a major change in the application of the doctrine in this circuit. Prior to Heitkamp, the doctrine was considered in cases which focused on whether a transfer to an old or previous creditor was preferential. . . . After Heitkamp, preference attacks on transfers to new creditors in earmarking situations must be analyzed in terms of this net result rule to determine if there has been a transfer of property of the debtor."); Forker v. Duenow Management Corp. (In re Calvert), 227 B.R. 153, 157 (citing Heitkamp for proposition that the earmarking doctrine applies only if the new and old creditor enjoy the same priority). AlliedSignal's manipulation of the language in Heitkamp, albeit somewhat ambiguous, is not well taken.
Next, the Defendant argues that this Court should follow the holding in Herzog v. Sunarhauserman (In re Network 90 Degrees, Inc.), 126 B.R. 990 (N.D.Ill.1991) (hereinafter "Network 90"). In Network 90, the District Court for the Northern District of Illinois held that certain transfers made from customers of the debtor directly to one of the debtor's creditors (by means of checks made payable jointly to the debtor and the creditor) were subject to the earmarking doctrine and therefore not preferences even though they were *379 made within the preference period. Id. Although the facts of Network 90 are remarkably similar to the instant case, this Court declines to follow the holding of Network 90 because it is not binding precedent in this jurisdiction, and perhaps more importantly, we do not believe that it is consistent with the earmarking doctrine as enunciated by the Eighth Circuit.[3]
The court in Network 90 rested its holding almost entirely on the fact that the debtor did not have control over the funds. Id. at 996 ("[W]hat is crucial to the finding of earmarking in these circumstances is . . . the debtor's lack of control over the funds received and forwarded to the existing creditor."). It reasoned that because the debtor did not have control over the funds, the funds never became property of the estate; since they never became part of the estate, the transfer of them to an existing creditor did not diminish the estate; therefore, the transfers were not preferential. We decline to adopt this reasoning for a number of reasons. First, control over the funds is not dispositive, the net effect of the transfer on the estate is. Heitkamp, at 1089. Second, even under the "net effect" test, the facts of Network 90 would not warrant the application of the earmarking doctrine. The court in Network 90 reasoned, in the same vein as the defendants now argue, that because a supplier of an essential component is paid directly from the proceeds of the debtor's sale of the product, the estate is not diminished. However, this reasoning fails to appreciate that this arrangement is equivalent to giving the supplier a security interest in the accounts receivable, which the supplier did not have in Network 90 and does not have in the instant case, and it ignores the fact that the price obtained by the debtor for the sale of its product most likely includes more than just cost of the component supplied. Third, the application of the earmarking doctrine to the payment of a debtor's supplier by a debtor's customers has already been rejected by this Court. See In re R.M. Taylor, Inc., Memorandum Opinion, entered September 30, 1999 (J. Federman) (unpublished).
Finally, the Defendant argues that there was no diminution of the estate, but rather, the estate was enhanced by the transaction. If the Court were to ignore the distinctions between secured and unsecured obligations, this argument might have some merit, but that is not the case. While the Court is sympathetic to Defendant's position that it provided the Debtor with 18 engines and expected to be paid directly from the Air Force's payments to the Debtor (by means of the Escrow Account), the Court cannot ignore the fact that AlliedSignal did not properly perfect its security interest in those payments. Payments made from the "collateral" of their purported security interest cannot be anything but preferential when the security interest in the Escrow Account has already been avoided as preferential. In effect, the Defendant is asking the Court to replace the Debtor's unsecured obligation to AlliedSignal with a secured obligation (albeit a security interest in funds originating from a third party), and that cannot be done through use of the earmarking doctrine. Heitkamp, at 1089.
For the reasons stated herein, the Court finds that the $325,319.45 transferred from the Escrow Account to AlliedSignal within the 90-day preference period was preferential *380 pursuant to 11 U.S.C. § 547(b). Accordingly, it is
ORDERED that the Trustee's Motion for Summary Judgment be and is hereby GRANTED, and the Trustee / Plaintiff, Mark G. Stingley, is awarded judgment against the Defendant, AlliedSignal, Inc., in the amount of $325,319.45. It is
FURTHER ORDERED that Defendant, AlliedSignal, Inc.'s Motion for Summary Judgment be and is hereby DENIED.
SO ORDERED.

NOTES
[1]  In the Joint Pretrial Statement, the parties stated that Allied had an additional defense, which was that the $325,319.45 in payments made to Allied were not preferential because Allied held a "perfected and unavoidable" security interest in the Escrow Account. However, Allied appeared to abandon this defense in its Motion for Summary Judgment and in its Suggestions, inasmuch as it was never mentioned in either. This is just as well since, as the Trustee correctly points out, Allied's security agreement was not "unavoidable," and was, in fact, avoided pursuant to the Stipulation and Order Avoiding AlliedSignal's Security Interest, entered by this Court on January 22, 1999.
[2]  See supra, n. 1.
[3]  The Court also pauses to note that the decision in Network 90 was contrary to a number of other bankruptcy court decisions holding that the earmarking doctrine cannot be applied to transfers from an entity owing money to a debtor to a debtor's creditor, see, e.g., In re Funding Systems Asset Management Corp., 111 B.R. 500 (Bankr.W.D.Pa.1990); In re Buono, 119 B.R. 498 (Bankr.W.D.Pa.1990). See also, Network 90, at 995 (recognizing that its holding was contrary to other courts' treatment of similar issue). Contrary to the suggestions of the Defendant, Network 90 has been criticized for taking an over-simplified approach to the earmarking doctrine. See Tolz v. Barnett Bank of South Florida (In re Safe-T-Brake of South Florida, Inc.), 162 B.R. 359, 365-66 (Bankr.S.D.Fla.1993)
