Stock Option Committee, has adopted the amended and restated Drew Industries

(Section 2(b)(ii)); (5) increase the number of shares which may be granted to
any existing or future participant under the Amended Plan (Section 2(b)) as a
result of a 2 for 1 stock split in March 1997; (6) limit the number of shares
with respect to which repriced options can be granted (Section 4(d)); (7)
increase the number of "Formula Options" automatically granted to members of the
Stock Option Committee (Section 4(e)) as a result of a 2 for 1 stock split in
March 1997; and (8) clarify that the Stock Option Committee may not reduce the
exercise price for any stock option granted pursuant to the Amended Plan below
fair market value of the Common Stock as of the date of grant, except as
otherwise provided in the Amended Plan (Section 13(b)).
