Item 1.01. Entry into a Material Definitive Agreement.

On July 31, 2007, Polypore, Inc. (“Polypore”), a wholly owned subsidiary of Polypore International, Inc. (the “Company”), merged with and into the Company. On July 31, 2007, the Company, the Guarantors (as defined therein) and The Bank of New York, as trustee (the “Trustee”), executed the Second Supplemental Indenture (the “Second Supplemental Indenture”) supplementing the Indenture, dated as of May 13, 2004, by and among Polypore, the Guarantors and the Trustee (as amended, supplemented or otherwise modified, the “Indenture”), relating to Polypore’s 8¾% Senior Subordinated Notes due 2012 (the “8¾% Notes”). Pursuant to the Second Supplemental Indenture, the Company, as successor by merger to Polypore, assumed Polypore’s obligations with respect to the due and punctual payment of the principal of, premium, if any, and interest on all of the 8¾% Notes and the performance of every covenant and all obligations of Polypore under the 8¾% Notes, the Indenture and the Registration Rights Agreement, dated as of May 13, 2004, by and among Polypore, the Guarantors, and the initial purchasers named therein, to be performed or observed on the part of Polypore. Each of the Guarantors confirmed its obligations under the Indenture, the related guarantees and the 8¾% Notes.

The Second Supplemental Indenture is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 1.02 Termination of a Material Definitive Agreement.

Item 2.04 Triggering Events that Accelerate or Increase a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement.

On July 16, 2007, the Company announced that it had completed its tender offer to purchase for cash its 10½% Senior Discount Notes due 2012 (the “10½% Notes”). The tender offer expired on July 13, 2007. As of the expiration time, $299,480,000 aggregate principal amount at maturity of the 10½% Notes were tendered, representing approximately 99.83% of the aggregate principal amount at maturity outstanding.

On July 30, 2007, the Trustee, on behalf of the Company and at the Company’s expense, provided notice of redemption to the holders of the remaining 10½% Notes outstanding. Pursuant to the terms of the Indenture, dated as of October 18, 2004, between the Company and the Trustee (the “10½% Indenture”), once notice of redemption is mailed, the 10½% Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price stated in the notice.

On July 30, 2007, the Company satisfied and discharged the 10½% Indenture. Upon such satisfaction and discharge, the 10½% Indenture ceased to be of further effect (except for certain rights of the Trustee).
