MEMORANDUM AND ORDER
J. BRATTON DAVIS, Bankruptcy Judge.In this adversary proceeding the trustee seeks to avoid under 11 U.S.C. § 547 an alleged preferential transfer of $10,355.07 made by Jay Terrell Slater (the debtor) to the defendant, Greenville Local Development Corporation. The defendant denies that it received a preferential transfer and argues that the transfer is not avoidable in that it falls within the exceptions of § 547(c)(1), § 547(c)(3), and § 547(c)(5).
STIPULATED FACTS
The parties stipulated the following:
On October 4, 1983 an order was issued granting Jay Terrell Slater (the debtor) relief under Chapter 7 of the Bankruptcy Code. Prior to the filing of the petition the debtor operated a printing and copying business known as “The Copy Center”.
On June 28, 1983 the debtor was awarded a contract with the Greenville County School District and on June 30, 1983 the debtor applied for a $20,000 loan from the defendant for operating capital to perform the contract.
By a letter dated July 13, 1983, the defendant issued its commitment for the loan to the debtor. On July 15, 1983 the debtor executed a promissory note in the amount of $20,000 to the defendant and the defendant paid the debtor the proceeds of the loan. The debtor also executed an agreement, dated July 15, 1983, which provided for the assignment of the proceeds from the debtor’s contract with the Greenville County School District (the school district) to the defendant; and a letter was sent to the school district notifying it of the assignment.
On September 6, 1983, upon completion by the debtor of the work under the contract, the school district made payment by a check made out to the debtor and to the defendant, as joint payees, in the amount of $29,927.95. The check was endorsed by both the debtor and the defendant and the full amount was deposited into the defendant’s checking account. The defendant deducted the principal and the interest it was owed and issued its check for $9,572.88 and a receipt for payment of $20,355.07, both dated September 6, 1983, to the debtor.
ISSUES
The issues are: (1) whether the payment of $20,355.07 by the debtor to the defendant creditor within 90 days before the Chapter 7 petition for relief was filed is a preferential transfer within the meaning of § 547; (2) whether the granting of the loan and the repayment of the loan were substantially contemporaneous so as to fall within the exception provided in § 547(c)(1); and (3) whether the assignment of the contract rights was perfected, therefore, not avoidable under § 547(c)(3) and § 547(c)(5).
DISCUSSION AND CONCLUSION
I
The payment of $20,355.07 by the debtor to the defendant on September 6, 1983 was a transfer within the meaning of § 547(b). This transfer was made to a creditor of the debtor within the meaning of § 547(b)(1) for or on account of an antecedent debt evidenced by the note dated July 15, 1983.
The debtor was insolvent on September 6,1983, the date of this transfer, within the meaning of § 547(b)(3) and § 101(26), in that the debts and obligations of the debtor exceeded the fair value of his assets at the time of the transfer. Counsel for the de*188fendant has conceded that the transfer occurred within 90 days before the date of filing the petition for relief under Chapter 7. The defendant received more from this transfer than it would have received if the case had proceeded as a case under Chapter 7 of the Bankruptcy Code and the transfer had not been made. Therefore, it appearing that all of the requirements of § 547(b)1 have been satisfied, the payment of $20,355.07 by the debtor to the defendant on September 6, 1983 was a preferential transfer.
11
The defendant contends that the transfer was an exception under § 547(c)(1). “This exception is limited to situations where the parties intend the transfer to be a. contemporaneous exchange for value and the exchange is, in fact, substantially contemporaneous.” (Emphasis added). In re Economy Milling, 37 B.R. 914, 920 (D.S.C.1983). Inasmuch as the promissory note was given on July 15, 1983 and the payment thereof was made on September 6, 1983, this transaction was not substantially contemporaneous. It having been determined that the transaction was not substantially contemporaneous, a determination as to whether the exchange was intended to be contemporaneous is moot. Section 547(c)(1) is inapplicable to this transaction.
Ill
The defendant further argues that the transfer is unavoidable as coming under the exceptions contained in § 547(c)(3)2 and § 547(c)(5)3. Both of these subsections require a perfected security interest. The defendant contends that it had a perfected security interest in the account receivable which the debtor had with the Greenville County School District and that the transfer was made in payment of this receivable; however, no financing statement has been filed by the defendant with the Secretary of State reflecting this assignment as required by section § 36-9-302(1) of the Code of Laws of South Carolina (1976).
The defendant posits that the assignment of the contract rights from the school district is within the exception to the filing requirement provided in § 36-9-302(1)(e).4 *189However, because the debtor’s account receivable, assigned to the defendant, constituted most of the debtor’s outstanding accounts receivable, the assignment transferred “a significant part of the outstanding ... contract rights” of the debtor so as to take it out of the exception to the filing requirement found in § 36-9-302(l)(e). Thus, the defendant’s security interest in the assignment of contract rights was un-perfected at the time of the transfer.
Accordingly, the transfer does not fall within the exceptions set forth in § 547(c)(3) and § 547(c)(5).
ORDER
It is, therefore, ORDERED, ADJUDGED AND DECREED:
1. The payment of $20,355.07 by the debtor to the defendant on September 6, 1983 was a preferential transfer within the meaning of § 547;
2. The transfer was not a substantially contemporaneous exchange; therefore, the transfer does not fall within the exception set forth in § 547(c)(1);
3. The defendant’s security interest in the assignment of the account receivable of the debtor from the school district was unperfected; therefore, the transfer does not fall within the exceptions set forth in § 547(c)(3) and § 547(c)(5);
4. The transfer is void; and
5. L. Winston Lee, as trustee for the estate of Jay Terrell Slater, debtor, is hereby granted judgment against the defendant, Greenville Local Development Corporation, for the sum of $20,355.07.
