file a Form25 with the SEC, to request the removal of the
Common Stock from listing on the NYSE and from registration
under Section12(b)of the Securities Exchange Act of 1934, as
amended (the Exchange Act). The Company intends to file
with the SEC a certification on Form15 under the Exchange Act
requesting the termination of the registration of the Common
Stock under Section12(g)of the Exchange Act and the suspension
of the Companys reporting obligations under Sections13
and15(d)of the Exchange Act. The disclosure set forth in the

control in the Company occurred and the Company became an
indirect wholly owned subsidiary of Parent. The disclosure set
forth in the Introductory Note above and under Items 2.01 and
5.02 of this Current Report on Form8-K is incorporated by
reference into this Item5.01.

On May8, 2017, to the terms of the Merger Agreement and
effective as of immediately prior to the Effective Time, all of
the directors of the Company resigned from the board of
directors of the Company (the Board) and any committees
of the Board of which they were members. The resignations were
not the result of any disagreement with the Company and were
effectuated solely in connection with the Merger. Also on May8,
2017, to the terms of the Merger Agreement and effective as of
the Effective Time, the directors of Merger Sub became
directors of the Company and such directors will serve on the
Board until his successor is duly elected and qualified or
until his earlier death, resignation or removal.

Merger and effective as of immediately prior to the Effective
Time, each of the chief executive officer; chief financial
officer; vice president, general counsel and secretary; and
president, Headwaters Siding and Roofing (each a named
executive officer) has resigned his position as an officer of
the Company. The resignations were not the result of any
disagreement with the Company and were effectuated solely in
connection with the Merger. Each of the individuals described
in this paragraph have also been terminated as employees of the
Company other than for cause in a manner that entitles them to
severance payments under their existing agreements, effective
as of the Effective Time. The terminations were not the result
of any disagreement with the Company and were effectuated
solely in connection with the Merger.

On May6, 2017, the Company entered into a Termination Agreement
(the Termination Agreement) with the Companys Chairman
of the Board and Chief Executive Officer, Kirk A. Benson. The

Termination Agreement confirmed the payments due to Mr.Benson
under the Merger Agreement and the Companys employee benefit
plans and under his Employment Agreement with the Company dated

The Employment Agreement provided that for a three-year period
following Mr.Bensons retirement as an executive officer of the
Company (the Extended Term), Mr.Benson would continue
employment as a non-executive employee and provide consulting
services to the Company. During the Extended Term, he would
have received annual compensation of $300,000. The Termination
Agreement amends the Employment Agreement to eliminate the
consulting arrangement, and in consideration of the termination
of the consulting arrangement Mr.Benson will receive a lump-sum
payment of $900,000.
