Merger Agreement

This Amendment No. 4 is being filed to report the termination of beneficial ownership of all shares of Common Stock previously beneficially owned by the Reporting Persons as a result of the consummation of the merger (the “Merger”) contemplated by the Agreement and Plan of Merger, dated as of March 16, 2017 (the “Merger Agreement”), by and among AERT, Oldcastle Architectural, Inc., a Delaware corporation (“Parent”), and Oldcastle Ascent Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Parent (“Merger Sub”).

On May 1, 2017 (the “Effective Time”), Merger Sub was merged with and into AERT, with AERT surviving the merger as a wholly-owned subsidiary of Parent. Subject to the terms and conditions of the Merger Agreement, at the Effective Time, each share of Common Stock outstanding immediately prior to the Effective Time was converted into the right to receive $0.135936 in cash, and each share of AERT Series E Convertible Preferred Stock, par value $0.01 per share (“Preferred Stock”), outstanding immediately prior to the Effective Time was converted into the right to receive $2,603.483278 in cash, in each case, without interest and subject to any applicable withholding taxes, and other than any shares of Common Stock or Preferred Stock owned by AERT (which were automatically canceled with no consideration paid therefor) and those shares of Common Stock with respect to which stockholders properly exercised appraisal rights and have not effectively withdrawn or lost their appraisal rights.

- 9 -

Accordingly, at the Effective Time and pursuant to the Merger, each of the Reporting Persons disposed of all shares of Common Stock that were beneficially owned by such Reporting Persons immediately prior to the Effective Time and ceased to be a beneficial owner of 5.0% or more of the Issuer’s shares.

ITEM 5.

(c) Other than as described in Item 4 above, the Reporting Persons have not effected any transactions in the Common Stock or the Preferred Stock during the 60 days prior to the Effective Date.

(d) Not applicable.

(e) Each of the Reporting Persons ceased to be a beneficial owner of 5.0% or more of the Common Stock on May 1, 2017.
