ITEM 2.05     COSTS ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES.

         On December 30, 2004, the Board of Directors committed NATCO Group Inc.
to a restructuring plan with the intent of simplifying our corporate structure
by streamlining the corporate organization and reducing operating costs.
Effective January 1, 2005, we will restructure our business segments by end-use
markets and related technologies into three segments: Gas Technologies, Oil &
Water Technologies and Automation & Controls. As a result of these changes and
others, we expect to benefit from greater efficiencies and revenue growth while
immediately pursuing cost reduction initiatives designed to reduce expenses by
at least $10 million over the next 12-18 months, half of which are expected to
be realized in 2005. The plan includes workforce reductions, primarily involving
our UK operations. We expect to record severance and other costs primarily in
the fourth quarter of 2004 and first quarter of 2005 approximating $2.5 million,
pre-tax, and may incur additional severance and other expenses in future periods
as these initiatives become fully implemented. We expect to complete the plan in
the second quarter of 2005.

         A copy of our January 3, 2005 press release with respect to various
corporate announcements, including the proposed reorganization, is attached as
Exhibit 99.1 and is incorporated by reference into this Item 2.05.

         Statements made in this report that are forward-looking in nature are
intended to be "forward-looking statements" within the meaning of Section 21E of
the Securities Exchange Act of 1934 and may involve risks and uncertainties.
Forward-looking statements include statements regarding future events or the
future performance of NATCO Group Inc., including but not limited to statements
regarding our ability to reduce operating expenses and the amount of severance
costs. These statements are based on current expectations, forecasts and
assumptions and involve a number of risks and uncertainties that could cause
actual results to differ materially from those anticipated by these statements.
Readers are referred to our documents filed with the Securities and Exchange
Commission, including our Annual Report on Form 10-K and Quarterly Reports on
Form 10-Q, which identify significant risk factors that could cause actual
results to differ from those contained in the forward-looking statements. We
assume no obligation to update this information, except as may be required by
law.
