Item 1.01 Entry Into a Material Definitive Agreement.

On November 16, 2006, Environmental Tectonics Corporation (“ETC”) executed an Unsecured Promissory Note (the “Note”) in favor of H.F. Lenfest (“Lenfest”) in the aggregate principal amount of $3,000,000. Pursuant to the terms of the Note, ETC can borrow up to $3,000,000 in increments of $1,000,000 prior to the Maturity Date. Pursuant to the terms and conditions of the Note, on November 17, 2006, ETC borrowed $3,000,000.

All outstanding and unpaid interest on the Note is due and payable on the earlier of (i) October 6, 2007 or (ii) such date as ETC draws down funds sufficient to repay the amount due under the Note pursuant to the Preferred Stock Purchase Agreement, dated as of April 6, 2006, between ETC and Lenfest (the “Maturity Date”).

Borrowings made pursuant to the Note will bear interest at an annual rate of six (6%) percent with such interest beginning to accrue on the date of the funding of each loan and, to the extent not paid, compounding on the first day of each month.

The Note provides for customary events of default including, but not limited to, the nonpayment of any amount payable when due, certain bankruptcy, insolvency or receivership events and the imposition of certain judgments. Upon the occurrence of an event of default, Lenfest has the right to accelerate the Maturity Date of the Note and demand immediate payment of all amounts payable there under.

The foregoing description is qualified in its entirety by the terms set forth in the Note, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
