This Amendment No. 2 is being filed by each of Midland Fabricators and Process
Systems, L.L.C., a Louisiana limited liability company ("Midland"), Midland
Acquisition, Inc., a Louisiana corporation ("Midland Acquisition"), William A.
Hines and Jeanne M. Hines McDaniel. This Amendment No. 2 amends and supplements
the Schedule 13D filed with the Securities and Exchange Commission on June 23,
2004 and Amendment No. 1 to the Schedule 13D ("Amendment No. 1") filed with the
Securities and Exchange Commission on September 8, 2004 by each of Midland
Fabricators and Process Systems, L.L.C., a Louisiana limited liability company,
William A. Hines and Jeanne M. Hines McDaniel. Except as specifically provided
herein, this Amendment No. 2 does not modify any of the information previously
reported on the Schedule 13D or Amendment No. 1. Unless otherwise defined
herein, all capitalized terms shall have the meanings ascribed to them in the
Schedule 13D.

ITEM 2.  IDENTITY AND BACKGROUND

      There are no material changes to the information previously reported in
Item 2 of the Schedule 13D and Amendment No. 1.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATIONS

      There are no material changes to the information previously reported in
Item 3 of the Schedule 13D and Amendment No. 1.

ITEM 4.  PURPOSE OF TRANSACTION

      Item 4 of the Schedule 13D is hereby amended and supplemented to add the
following:

      On October 6, 2004, Midland, Midland Acquisition, William A. Hines and
Jeanne M. Hines McDaniel filed with the Securities and Exchange Commission (the
"Commission") a Schedule 13E-3 detailing Midland's plan to take UNIFAB private
through a short-form merger. On November 19, 2004, the Schedule 13E-3 was
amended. Such Schedule 13E-3 and any amendments thereto are hereby incorporated
by reference into this Schedule 13D. While the proposed short-form merger
transaction is consistent with Midland's current intent, should any other
possible transaction occur that would provide more value to the common
shareholders of UNIFAB, Midland would consider such other transaction and
abandonment of the proposed short-form merger.

      There are no material changes to the information previously reported in
Item 5 of the Schedule 13D and Amendment No. 1.

incorporated herein by reference, there are no material changes to the
information previously reported in Item 6 of the Schedule 13D and Amendment No.
1.

ITEM 7.  MATERIAL TO BE FILED AS EXHIBITS
