      Patrick S. O'Keefe, Chief Executive Officer, commented, "We are pleased
with the third 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 quarterly year over year sales, our
internal growth rate was 10% and contributed $17,987,000, the acquisitions of
McCoy Enterprises, Inc, TEAM Precision Pipework, Ltd, and Flowmatic Systems,
Inc. contributed $10,756,000, or 6%, and the change in foreign exchange rates
contributed $5,938,000, or 3%, 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 $4,653,000 of revenue in the
third 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 third
quarter of 2004 increased 20% to $145,056,000 compared to $121,001,000 for the
third quarter of 2003. This increase in North American sales was due to internal
sales growth of $10,462,000, or 9%, the inclusion of $8,358,0000 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
$4,653,000 in sales resulting from the consolidation of Jameco International
LLC, and $582,000 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 growth in the North American
wholesale market was 9% over the third 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
growth in the North American home improvement retail market was 8% for the third
quarter of 2004 over the third quarter of 2003.

      Mr. O'Keefe continued, "We derived 29% of our total sales for the third
quarter of 2004 from Europe. European sales increased $12,175,000, or 24%,
compared to the third quarter of 2003. This increase includes internal sales
growth of $4,421,000, or 9%, the inclusion of $2,398,000 in sales from the
acquisition of TEAM Precision Pipework, Ltd., acquired on April 16, 2004, and
$5,356,000 due to favorable foreign exchange rates associated with the
strengthening of the euro versus the U.S. dollar. The internal sales growth is
attributable to market share gains in the European wholesale markets."

      Mr. O'Keefe continued, "We are pleased with the positive operating trends
in our Chinese subsidiaries. The plants continue to increase capacity
utilization and gain manufacturing efficiencies. These increased manufacturing
efficiencies allowed our Chinese operations to generate a profit for the second
consecutive quarter. Year-to-date, the operations are also profitable."



      Mr. O'Keefe continued, "In the third quarter of 2004 we recorded a tax
benefit of approximately $876,000 for prior years state tax credits. We also
recorded in cost of sales a pre-tax charge of approximately $567,000 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. In this quarter we incurred
and recorded pre-tax charges of approximately $1,200,000 for costs to comply
with the Sarbanes-Oxley Act ("SOX"). In addition, we expect to record
approximately $3,000,000 in the fourth quarter of 2004 for additional costs to
comply with SOX".

      On January 5, 2004, the Company acquired substantially all of the assets
of Flowmatic Systems, Inc. located in Dunnellon, Florida, for approximately
$16,800,000 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
Pipework, Ltd., located in Ammanford, West Wales, United Kingdom for
approximately $17,200,000 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 100% of the stock of McCoy
Enterprises, Inc., which we subsequently renamed Orion Enterprises, Inc.
(Orion), located in Kansas City, Kansas, for approximately $27,800,000 in cash.
Orion distributes its products under the brand names of Orion, FloSafe 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.
