respectively.



      Patrick S. O'Keefe, Chief Executive Officer, commented, "We are pleased
with the second quarter results from all three of our geographic segments, North
America, Europe and China. Our overall increase in sales was achieved by
internal growth, the contribution from acquired companies, and the change in
foreign exchange rates. In comparing our sales during the second quarter of 2004
with the second quarter of 2003, our internal growth rate, which was 11%,
contributed $19,069,000, the acquisitions of McCoy Enterprises, Inc, TEAM
Precision Pipework, Ltd, Flowmatic Systems, Inc., and Giuliani Anello S.r.l.
contributed $11,299,000 and the change in foreign exchange rates contributed
$3,074,000 due primarily to the strengthening of the euro versus the U.S.
dollar. Additionally, due to the adoption of Financial Accounting Standards
Board Interpretation No. 46, "Consolidation of Variable Interest
Entities-Revised" (FIN 46R) we recorded $5,740,000 of revenue in the second
quarter of 2004 as a result of the consolidation of our minority owned
subsidiary, Jameco International LLC."

      Mr. O'Keefe continued, "Our North American segment sales for the second
quarter of 2004 increased 22% to $144,522,000 compared to $118,162,000 for the
second quarter of 2003. This increase in North American sales was due to
internal sales growth of $14,300,000, the inclusion of $6,116,0000 in sales from
the acquisition of McCoy Enterprises, Inc., acquired on May 21, 2004, and
Flowmatic Systems, Inc., acquired on January 5, 2004, the inclusion of
$5,740,000 in sales resulting from the consolidation of Jameco International
LLC, and $204,000 due to favorable foreign exchange rates associated with the
strengthening of the Canadian dollar versus the U.S. dollar."

      Mr. O'Keefe continued, "Internal sales in the North American wholesale
market increased by 13% over the second quarter of 2003. This increase was led
by increased sales of backflow prevention units, as well as, strength in our
plumbing and under-floor radiant heating product lines. Our internal sales into
the North American home improvement retail market increased by 11% for the
second quarter of 2004 over the second quarter of 2003.

      Mr. O'Keefe continued, "We derived 29% of our total sales for the second
quarter of 2004 from Europe. Sales in Europe for the second quarter of 2004
increased $10,752,000, or 21%, compared to the second quarter of 2003. This
increase is due to the inclusion of $5,183,000 in sales from the acquisitions of
TEAM Precision Pipe Work, Ltd., acquired on April 16, 2004 and Giuliani Anello
S.r.l. acquired on July 30, 2003, $2,870,000 due to favorable foreign exchange
rates associated with the strengthening of the euro versus the U.S. dollar and
internal sales growth of $2,699,000. The internal sales growth is attributable
to market share gains in the European wholesale markets."

      Mr. O'Keefe continued, "We are pleased that our China segment was
profitable in the second quarter. We are experiencing an improved order entry
rate at our TWT joint venture in Tianjin. At our recently established wholly
owned facility, also in Tianjin, we were able to absorb all our manufacturing
expenses due to improved manufacturing efficiencies and increased production
volumes. Also, in the quarter we purchased the 40% equity interest in Shida that
had been held by our former joint venture partner, giving us 100% ownership."



      Mr. O'Keefe continued, "For the second quarter of 2004 we recorded a
pre-tax charge of approximately $560,000 in cost of goods sold for accelerated
depreciation for both the expected closure of a U.S. manufacturing plant and a
reduction in the estimated useful lives of certain manufacturing equipment, both
part of our cost reduction program. This represents a reduction from the amount
recorded in the first quarter of 2004 because we have postponed the expected
closure date of a manufacturing facility and extended the estimated useful lives
of production equipment due to revised production requirements. Also in this
quarter we have incurred and recorded pre-tax charges of approximately
$1,400,000 for costs to comply with new accounting and financial controls
requirements under the Sarbanes-Oxley Act.

      On January 5, 2004, the Company acquired substantially all of the assets
of Flowmatic Systems, Inc. located in Dunnellon, Florida, for approximately
$16,700,000 in cash. Flowmatic designs and distributes high quality reverse
osmosis components and filtration equipment. Their product lines include
stainless steel and plastic housings, filter cartridges, storage tanks, control
valves, as well as complete reverse osmosis systems for residential and
commercial applications.

      On April 16, 2004, the Company acquired 90% of the stock of TEAM Precision
Pipe Work, Ltd., located in Ammanford, West Wales, United Kingdom for
approximately $16,500,000 subject to final adjustments, if any, as stipulated in
the purchase and sale agreement. TEAM custom designs and manufactures
manipulated pipe and hose tubing assemblies, which are utilized in the heating
ventilation and air conditioning markets. TEAM is a supplier to major original
equipment manufacturers of air conditioning systems and several of the major
European automotive air conditioning manufacturers

      On May 21, 2004, the Company acquired McCoy Enterprises, Inc., which we
subsequently renamed Orion Enterprises, Inc., located in Kansas City, Kansas,
for approximately $27,800,000 in cash. Orion distributes its products under the
brand names of Orion, Flo Safe and Laboratory Enterprises. Orion's product lines
include a complete line of acid resistant waste products, double containment
piping systems, as well as, a line of high purity pipes, fittings and faucets.
