The Executors, the July 2005 Trust, the Second July 2005 Trust, the Trustees and

This Statement relates to the Class B common stock, no par value, of Sequa
Corporation (the "Company").

Item 4. Purpose of Transaction.

Item 4 of the Schedule is hereby amended by inserting the following text at the
end thereof:

The Company has entered into an Agreement and Plan of Merger, dated as of July
8, 2007 (the "Merger Agreement"), with Blue Jay Acquisition Corporation, a
Delaware corporation ("Parent"), and Blue Jay Merger Corporation, a Delaware
corporation and a wholly-owned subsidiary of Parent ("Merger Co"). Parent and
Merger Co are entities directly and indirectly owned by Carlyle Partners V, L.P.
and its affiliates (collectively, "Carlyle"). The Merger Agreement contemplates
that Merger Co will be merged with and into the Company (the "Merger"), with the
Company continuing as the surviving corporation and a wholly owned subsidiary of
Parent.

On July 8, 2007, in connection with the execution of the Merger Agreement, each
of the Filing Persons and certain other stockholders of the Company
(collectively, the "Principal Stockholders"), entered into a Voting Agreement
(the "Voting Agreement") with the Company, Parent and Merger Co. Pursuant to the
Voting Agreement, each of the Principal Stockholders has agreed, among other
things and subject to certain exceptions, (i) to vote all of his, her or its
shares of Class A Common Stock and Class B Common Stock of the Company
(together, the "Common Stock") in favor of the approval of the Merger Agreement
and against certain actions involving the Company that would have the effect of
impeding, interfering with, delaying, postponing or impairing the Merger, (ii)
to grant Parent and its designees an irrevocable proxy to vote such shares with
respect to the foregoing matters and (iii) not to transfer or dispose of any of
his, her or its shares of Common Stock of the Company (other than to transferees
who agree to be bound by the Voting Agreement).

The foregoing description of the Voting Agreement does not purport to be
complete and is qualified in its entirety by reference to the full text of the
Voting Agreement, which is filed as Exhibit 3 hereto and is incorporated herein
by reference.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        Securities of the Issuer.

Item 6 of the Schedule is hereby amended by inserting the following text at the
end thereof:

On July 8, 2007, each of the Filing Persons entered into the Voting Agreement,
pursuant to which each of the Principal Stockholders has agreed, among other
things and subject to certain exceptions, (i) to vote all of his, her or its
shares of Common Stock in favor of the approval of the Merger Agreement and
against certain actions involving the Company that would have the effect of
impeding, interfering with, delaying, postponing or impairing the Merger, (ii)
to grant Parent and its designees an irrevocable proxy to vote such shares with
respect to the foregoing


                                        2



matters and (iii) not to transfer or dispose of any of his, her or its shares of
Common Stock of the Company (other than to transferees who agree to be bound by
the Voting Agreement).

Item 7. Materials to Be Filed as Exhibits.

end thereof:
