6. Commitments and Contingent Liabilities

  Outstanding standby and commercial letters of credit as of September
  30, 2005 approximated $18,824,000, a major portion of which serves as
  collateral for the Industrial Revenue Bond debt.

  In connection with the sale of certain subsidiaries in 2003, the
  Corporation provided typical warranties to the buyer (such as those
  relating to income taxes, intellectual property, legal proceedings,
  product liabilities and title to property, plant and equipment) which
  primarily expire with the statutes of limitations. Losses suffered by
  the buyer as a result of the Corporation's breach of warranties are
  reimbursable by the Corporation up to approximately $2,000,000. No
  amount has been paid to date and based on experience while owning the
  subsidiaries, the Corporation expects that no amounts will become due.

  During 2004, the Davy Roll operations received $1,498,000 (800,000
  GBP) of U.K. governmental grants toward the purchase and installation
  of certain machinery and equipment.  Under the agreement, the grants
  are repayable if certain conditions are not met including achieving
  and maintaining a targeted level of employment through March 2009.

7.Stock Option Plan

  On July 26, 2005, the Stock Option Committee of the Board of Directors
  agreed to issue to selected employees the remaining 45,000 stock
  options available under the 1997 Stock Option Plan, as amended.  The
  exercise price of $13.67 was equivalent to the market price on the
  date of grant; accordingly, no stock-based compensation expense was
  recognized.  The weighted-average fair value of the options, as of the
  date of grant using the Black-Scholes option-pricing model, was $3.08
  based on the following


                                  - 8 -


  assumptions: dividend yield of 2.9%, expected volatility of 26.3%,
  risk-free interest rate of 3.9% and expected option life of 5.7 years.
  The following table illustrates the effect on net income (loss) and
  earnings per common share if the Corporation had applied the fair
  value recognition provisions of Statement of Financial Accounting
  Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation."
  There were no options granted in 2004 and previously granted options
  are fully vested; accordingly there would be no effect on net income
  (loss) or earnings per common share in 2004.

9.Foreign Exchange and Futures Contracts

  Certain of the Corporation's operations are subject to risk from
  exchange rate fluctuations in connection with sales in foreign
  currencies.  To minimize this risk, forward foreign exchange contracts
  are purchased which are designated as fair value or cash flow hedges.
  As of September 30, 2005, approximately $62,027,000 of anticipated
  foreign denominated sales has been hedged with the underlying
  contracts settling at various dates through March 2010.  As of
  September 30, 2005, the fair value of contracts expected to settle
  within the next 12 months, which is recorded in other current
  liabilities, approximated $630,000 and the fair value of the remaining
  contracts, which is recorded in other noncurrent liabilities,
  approximated $1,114,000.  The change in the fair value of the
  contracts designated as cash flow hedges is recorded as a component of
  accumulated other comprehensive income (loss) and approximated
  $(970,000), net of income taxes, as of September 30, 2005. The change
  in fair value will be reclassified into earnings when the projected
  sales occur with approximately $(560,000) expected to be released to
  pre-tax earnings within the next 12 months. During the nine months
  ended September 30, 2005 and 2004, approximately $(692,000) and
  $(1,197,000), respectively, were released to


                                 - 10 -


  pre-tax earnings, and during the three months ended September 30, 2005
  and 2004, approximately $(135,000) and $(314,000), respectively, were
  released to pre-tax earnings.

  (Losses) gains on foreign exchange transactions approximated $(89,000)
  and $297,000 for the nine months ended September 30, 2005 and 2004,
  respectively, and $127,000 and $10,000 for the three months ended
  September 30, 2005 and 2004, respectively.

  In addition, one of the Corporation's subsidiaries is subject to risk
  from increases in the price of a commodity (copper) used in the
  production of inventory.  To minimize this risk, futures contracts are
  entered into which are designated as cash flow hedges.  At September
  30, 2005, approximately 98% or $2,690,000 of anticipated commodity
  purchases over the next 12 months are hedged.  The fair value of the
  contracts expected to be settled within the next 12 months
  approximated $690,000 and the fair value of the remaining contracts
  approximated $17,000 as of September 30, 2005.  The change in the fair
  value of the contracts designated as cash flow hedges is recorded as a
  component of accumulated other comprehensive income (loss) and
  approximated $446,000, net of income taxes, as of September 30, 2005.
  The change in the fair value will be reclassified into earnings when the
  projected sales occur with approximately $690,000, expected to be
  released to pre-tax earnings within the next 12 months.  During the
  nine months ended September 30, 2005 and 2004, approximately $485,000
  and $664,000, respectively, were released to pre-tax earnings and
  during the three months ended September 30, 2005 and 2004,
  approximately $131,000 and $240,000, respectively, were released to
  pre-tax earnings.

  Income (loss) before income taxes for the Forged and Cast Rolls
  segment for the nine months ended September 30, 2005 includes
  $2,320,000 of proceeds from the settlement of its business
  interruption insurance claim (see Note 12).



                                 - 11 -


  Income (loss) before income taxes for the Air and Liquid Processing
  segment for the nine and three months ended September 30, 2005 and
  2004 includes the majority of the legal and case management costs
  associated with personal injury claims and insurance recovery
  litigation related to asbestos-containing product and indemnity
  payments not expected to be recovered from insurance carriers (see
  Note 11).

11. Litigation and Environmental Matters

  The Corporation and its subsidiaries are involved in various claims
  and lawsuits incidental to their businesses.  In addition, claims have
  been asserted alleging personal injury from exposure to asbestos-
  containing components historically used in some products of certain of
  the Corporation's subsidiaries.  Those subsidiaries, and in some
  cases, the Corporation, are defendants (among a number of defendants,
  typically over 50 and often over 100) in cases filed in various state
  and federal courts.  The following table reflects information about
  these cases for the nine months ended September 30, 2005:

     Approximate open claims at end of period: 17,000
     Approximate gross settlement and defense costs: $7,559,000
     Approximate claims settled or dismissed during the period: 10,000

  Substantially all settlement and defense costs in the above table were
  paid by insurers.

  The asbestos-related claims, along with certain asbestos-related
  claims against another corporation insured under policies covering the
  Corporation and its subsidiaries, have given rise to insurance-
  coverage litigation in New York state court and in Pennsylvania
  federal court.  As described below, the insurance coverage disputes at
  issue in those litigations have been resolved with respect to nearly
  all parties by a comprehensive coverage arrangement.  The only party
  as to which a coverage arrangement has not yet been entered is one
  insurer that issued two known policies to one of the Corporation's
  subsidiaries.

  On February 7, 2003, Utica Mutual Insurance Company ("Utica") filed a
  lawsuit in the Supreme Court of the State of New York, County of
  Oneida ("Oneida County Litigation") against the Corporation and
  certain of the subsidiaries named in the underlying asbestos actions
  (the "Policyholder Defendants") and three other insurance carriers
  that provided primary coverage to the Corporation (the "Insurer
  Defendants").  In the lawsuit, Utica disputed certain coverage
  obligations to the Policyholder Defendants and asserted that the
  Insurer Defendants also had defense and indemnity obligations to the
  Policyholder Defendants.

  As of November 24, 2003, the Policyholder Defendants and Utica had
  reached an agreement that settled the Oneida County Litigation as
  among themselves(the "Utica Settlement"), although the Oneida County
  Litigation remained pending because settlement had not been reached
  with all of the Insurer Defendants.  Pursuant to the Utica Settlement,
  Utica accepted financial responsibility, subject to the limits of its
  policies and based on fixed defense percentages and specified
  indemnity allocation formulas, for a substantial majority of the
  asbestos personal injury claims arising out of



                                 - 12 -


  exposure to alleged asbestos-containing components in products
  distributed by the Policyholder Defendants that are subsidiaries of
  the Corporation.  Utica's agreed share of such defense and
  indemnification costs varies depending upon the alleged asbestos-
  containing product at issue, whether Utica's primary or umbrella
  policies are responsible for the claims and, for indemnification costs
  only, the years of the claimant's exposure to asbestos.  The
  Policyholder Defendants subsequently reached similar arrangements with
  four other of their historical insurers.

  On January 23, 2004, Utica sought the court's approval to file an
  amended complaint seeking additional relief against the Policyholder
  Defendants that is substantially identical to the relief Utica seeks
  against those defendants in a separate lawsuit filed by Howden
  Buffalo, Inc. ("Howden") in the United States District Court for the
  Western District of Pennsylvania (the "Pennsylvania Litigation") that
  is described below.  Utica also sought to add Howden as a defendant in
  the Oneida County Litigation.

  On November 25, 2003, Howden filed the Pennsylvania Litigation against
  the Corporation, Utica and two of the Insurer Defendants, and Howden
  subsequently amended its complaint to include three  other insurers,
  two of which had issued policies to the Company (collectively, the
  "Howden Insurer Defendants").  Howden alleged that (1) Buffalo Forge
  Company, a former subsidiary of the Corporation, or its predecessors
  (collectively or individually, "Buffalo Forge") had rights in certain
  policies issued by the Howden Insurer Defendants to the Corporation or
  its subsidiaries; (2) those rights were transferred in the 1993
  transaction whereby the Corporation sold all of the capital stock of
  Buffalo Forge to Howden Group America, Inc. and Howden Group Canada,
  Ltd.; and (3) those rights reside in Howden, as successor to Buffalo
  Forge.  In the lawsuit, Howden sought a judicial determination of the
  rights and duties of the Corporation and the Howden Insurer Defendants
  with respect to asbestos-related personal injury claims asserted
  against Howden arising from the historical operations of Buffalo
  Forge, as well as monetary damages from Utica as a result of its
  denial of Howden's rights under policies it issued that allegedly
  covered Buffalo Forge.

  As one of the Howden Insurer Defendants, Utica filed a cross-claim
  against the Corporation, and a third-party complaint against two of
  its subsidiaries, seeking a declaratory judgment that, to the extent
  Utica has defense or indemnity obligations to Howden: (1) Utica is
  entitled to contribution, subrogation and reimbursement from the
  Corporation or its subsidiaries with respect to defense and indemnity
  payments paid on behalf of the Corporation or its subsidiaries; and
  (2)the Corporation and its subsidiaries have no rights under the
  insurance contracts issued by Utica to Buffalo Forge.

  In September 2005, the Corporation and its subsidiaries, Howden, and
  all insurer parties to the Oneida County Litigation and Pennsylvania
  Litigation (except for one insurer that issued only two policies to
  one of the Corporation's subsidiaries) entered into a comprehensive
  coverage-in-place arrangement ("Coverage Arrangement")resolving as
  among themselves the disputed asbestos insurance coverage issues
  arising out of the historical products manufactured or distributed by
  Buffalo Forge Company and its former subsidiaries (the "Products").
  The Coverage Arrangement reaffirmed the Utica Settlement and coverage
  arrangements previously made by the


                                 - 13 -


  Corporation and its subsidiaries with four other insurers.  The
  Coverage Arrangement also includes an agreement pursuant to which all
  parties acknowledge that both the Corporation and its subsidiaries and
  Howden are entitled to coverage under policies covering the Products.
  The non-settling insurer and the Corporation and its subsidiaries did
  not assert claims against each other in either litigation, and are
  currently in negotiations.

  Based on the Corporation's claims experience to date with the
  underlying asbestos claims, the available insurance coverage and the
  identity of the subsidiaries that are named in the cases, the
  Corporation believes that the pending legal proceedings will not have
  a material adverse effect on its consolidated financial condition or
  liquidity.  The outcome of particular lawsuits, however, could be
  material to the consolidated results of operations of the period in
  which the costs, if any, are recognized.

  There can be no assurance that the Corporation or certain of its
  subsidiaries will not be subjected to significant additional claims in
  the future or that the Corporation's or its subsidiaries' ultimate
  liability with respect to these claims will not present significantly
  greater and longer lasting financial exposure than presently
  contemplated.  The Corporation has made an accrual in its financial
  statements to reflect its estimated share of costs for pending
  asbestos claims, based on deductible and similar features of its
  relevant insurance policies.  In addition, the Corporation incurred
  uninsured legal costs in connection with advice on certain matters
  pertaining to these asbestos cases including insurance litigation,
  case management and other issues.  Those costs amounted to
  approximately $762,000 and $332,000 for the nine and three months
  ended September 30, 2005, respectively, in comparison to $807,000 and
  $79,000 for the same periods of the prior year.

  With respect to environmental matters, the Corporation is currently
  performing certain remedial actions in connection with the sale of
  real estate previously owned and has been named a Potentially
  Responsible Party at four third-party landfill sites. In addition, as
  a result of the sale of certain subsidiaries, the Corporation retained
  the liability to remediate certain environmental contamination at two
  of the sold locations and has agreed to indemnify the buyer against
  third-party claims arising from the discharge of certain contamination
  from one of these locations, the cost for which was accrued at the
  time of sale.  Environmental exposures are difficult to assess and
  estimate for numerous reasons including lack of reliable data, the
  multiplicity of possible solutions, the years of remedial and
  monitoring activity required, and identification of new sites.
  However, in the opinion of management, the potential liability for all
  environmental proceedings of approximately $2,200,000 accrued at
  September 30, 2005 is considered adequate based on information known
  to date.

12. Flood Damage

  In September 2004, the Carnegie, Pennsylvania plant of the
  Corporation's Union Electric Steel subsidiary was damaged by flooding
  as a result of the remnants of Hurricane Ivan.  The Corporation
  received $5,740,000 toward its claim of which $3,000,000 was received
  in 2004.  Of the $2,740,000 received in 2005, $2,320,000 represents
  settlement of its business interruption insurance claim which was
  recorded as a reduction of costs of products sold (excluding
  depreciation) in the accompanying condensed consolidated


                                 - 14 -


  statements of operations.  The remaining $3,420,000 represents
  reimbursement of clean-up costs, repairs to machinery and recovery of
  certain fixed expenses.

13. Restatement

  Subsequent to the issuance of the Corporation's condensed consolidated
  financial statements for the nine and three months ended September 30,
  2004, the Corporation determined that deferred tax liabilities were
  not required to be provided for interest receivable from its U.K.
  subsidiary on intercompany debt owed to the Corporation.
  Additionally, subsequent to the issuance of the Corporation's
  consolidated financial statements for the year ended December 31,
  2004, the Corporation concluded, based on supplemental guidance
  issued, that auction-rate securities did not meet the definition of
  cash equivalents and should therefore be classified as short-term
  marketable securities. Accordingly, the accompanying condensed
  consolidated financial statements for the nine and three months ended
  September 30, 2004 have been restated from the amounts previously
  reported.

  The effect of reversing the deferred tax liabilities on the condensed
  consolidated statements of operations for the nine and three months
  ended September 30, 2004 were as follows:

                        (in thousands, except per share amounts)
                           Nine Months Ended    Three Months Ended

  The effect of correcting the classification of its investments in
  auction-rate securities from cash and cash equivalents to short-term
  marketable securities on the accompanying condensed consolidated
  statement of cash flows for the nine months ended September 30, 2004
  was as follows:

                                                  (in thousands)
                                                Previously     As

  The difference in cash and cash equivalents at the end of period of
  $26,430,000 represents the Corporation's investment in short-term
  marketable securities at September 30, 2004.

14. Recently Issued Accounting Pronouncements

  In November 2004, the Financial Accounting Standards Board (FASB)
  issued SFAS No. 151, "Inventory Costs" which confirms that accounting
  for abnormal amounts of idle facility expense, freight, handling
  costs, and wasted material (spoilage) be recognized as current period
  charges and that allocation of fixed production overheads to
  inventories be based on normal capacity of the production facilities.
  The provisions of SFAS No. 151 will become effective for the
  Corporation on January 1, 2006 and are not expected to have a
  significant effect on its financial condition or results of
  operations.

  In December 2004, the FASB issued SFAS No. 153, "Exchanges of
  Nonmonetary Assets" which amends previously issued guidance by
  eliminating the exception from fair value measurement for nonmonetary
  exchanges of similar productive assets and replaces it with an
  exception for exchanges which do not have commercial substance.  The
  provisions of SFAS No. 153 became effective for the Corporation on
  July 1, 2005. Until the Corporation enters into such transactions, the
  standard will not impact the Corporation's financial condition or
  results of operations.

  In December 2004, the FASB issued SFAS No. 123(R), "Shared-Based
  Payment" which requires companies to recognize compensation cost for
  stock options and other stock-based awards based on their fair value.
  Companies will no longer be permitted to follow the intrinsic value
  accounting method.  The provisions of SFAS No. 123(R) become effective
  for the Corporation on January 1, 2006.  The Corporation does not have
  any remaining options available for grant and granted options are
  fully vested; accordingly, the standard will not impact the
  Corporation's financial condition or results of operations unless the
  Corporation issues share-based payments in future years.

  In March 2005, the FASB issued an interpretation of SFAS No. 143,
  "Accounting for Conditional Asset Retirement Obligations" which
  clarifies the term conditional asset retirement obligation.  The
  interpretation did not impact the Corporation's financial condition or
  results of operations.

  In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and
  Error Corrections - a replacement of APB Opinion No. 20 and FASB
  Statement No. 3" which provides guidance for the accounting and
  reporting of a change in accounting principle.  It also applies to
  changes required by a newly-issued accounting pronouncement if that
  pronouncement does not provide such guidance. Previously, most changes
  in accounting principles were recognized by including the cumulative
  effect of changing to the new accounting principle in net income of
  the period of the change.  SFAS No. 154 requires retrospective
  application to prior periods and becomes effective for the Corporation
  on January 1, 2006.  Until the Corporation makes any such changes, the
  standard will not impact the Corporation's financial condition or
  results of operations.

            ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF
              FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Executive Overview

The Corporation currently operates in two business segments - the Forged
and Cast Rolls segment and the Air and Liquid Processing segment. After
several years of weak sales and earnings, the Forged and Cast Rolls
segment is benefiting from a strong global steel industry and the weaker
dollar which is improving export business, particularly to the Asian and
Indian markets.  Despite the continuing high level of raw material and
unprecedented energy costs, the Forged and Cast Rolls segment continues
to improve its income from operations.  Backlog of orders is at an all-
time high and is reflective of the demand for rolling mill rolls from
steel producers throughout the world.  Additional machinery brought on-
line late in 2004 at Davy Roll is contributing to operational
improvements and has added needed capacity.

The Air and Liquid Processing segment continues to experience weak sales
and earnings resulting from a decline in the level of capital spending by
the industrial sector and a slow down in construction spending.  In
particular, demand for lube oil pumps while expected to remain steady is
significantly below peak levels of several years ago due to reduced
demand for gas turbines. The segment is also being impacted by higher
material costs, the slow down in the construction industry particularly
related to air handling systems for the pharmaceutical, institutional and
health care markets, and the resulting decline in margins following
aggressive pricing by competitors as a reduced level of potential
business is pursued. Product offerings have been expanded but no
significant improvement in demand for air handling equipment is expected
until capital spending for new construction improves.

The following MD&A gives effect to the restatement discussed in Note 13
to the condensed consolidated financial statements for the nine and three
months ended September 30, 2004.

Operations for the Nine and Three Months Ended September 30, 2005 and 2004

Net Sales.  Net sales for the nine and three months ended September 30,
2005 were $177,873,000 and $56,632,000, respectively, compared to
$151,354,000 and $50,922,000,for the same periods of 2004.  A discussion
of sales for the Corporation's two segments is included below.  Order
backlogs approximated $289,246,000 at September 30, 2005 against
$164,981,000 at December 31, 2004. Although the backlog has improved for
both of the segments, the increase is principally attributable to the
Forged and Cast Rolls segment. Approximately $222,232,000 of the
September 30, 2005 backlog is scheduled for shipment after December 31,
2005.

Costs of Products Sold.  Costs of products sold, excluding depreciation,
were 79.5% and 82.1% of net sales for the nine months ended September 30,
2005 and 2004, respectively, and 78.8% and 86.7% of net sales for the
three months ended September 30, 2005 and 2004, respectively.  The
improvement is due primarily to receipt of $2,320,000 from the settlement
of the Corporation's business interruption insurance claim which is
recorded as a reduction of costs of products sold for the nine months
ended September 30, 2005, and raw material surcharges assessed in 2004
which are progressively flowing through to earnings in 2005.

                                 - 17 -


Selling and Administrative.  Selling and administrative expenses for the
nine and three months ended September 30, 2005 approximated 12.4% and
13.2% of net sales, respectively, and 13.9% and 14.1% of net sales for
the comparable prior year periods.  The decrease is due to higher sales
which dilute the effect of certain selling and administrative costs which
are fixed in nature.

Income (Loss) from Operations.  Income (loss) from operations for the
nine and three months ended September 30, 2005 approximated $9,300,000
and $2,945,000, respectively, against $1,188,000 and $(2,005,000) for the
comparable prior year periods.  A discussion of year-to-date and third
quarter results for the Corporation's two segments is included below.

Forged and Cast Rolls.  Sales and operating income for the nine and three
months ended September 30, 2005 improved over the flood-impaired periods
of the prior year as a result of greater demand from steel producers
throughout the world and better margins as surcharges and price increases
for raw material and energy began to flow through to earnings.
Additionally, during the second quarter, the segment finalized its 2004
flood-related business interruption insurance claim recording income of
$2,320,000.  Backlog approximated $256,152,000 as of September 30, 2005
in comparison to $138,729,000 as of December 31, 2004. The increase is
reflective of global demand for products for both the U.S. and U.K.
operations.  Approximately $209,960,000 of the September 30, 2005 backlog
is scheduled for shipment after 2005.

Air and Liquid Processing.  Sales for the nine and three months ended
September 30, 2005 were comparable to the same periods of the prior year.
Operating income declined due principally to the weak performance of the
air handling business which has been impacted by a decline in
construction activity and depressed pricing on available projects.
However, activity for this operation has begun to show signs of
improvement although margins continue to be depressed.  Results for the
pumps operation remain in line with the prior period.  Earnings for the
heat exchange coil business have improved due to an increase in sales,
particularly to electric-utility customers.  Backlog approximated
$33,094,000 as of September 30, 2005 in comparison to $26,252,000 as of
December 31, 2004; the increase is attributable to improvement in orders
for air handling units and receipt of long lead-time pump orders for U.S.
Navy ships. Approximately $12,272,000 of the September 30, 2005 backlog
is scheduled for shipment after 2005.

Other (Expense) Income.  Other (expense) income for the nine months ended
September 30, 2005 and 2004 approximated $(114,000) and $244,000,
respectively. The change is due primarily to losses on foreign exchange
transactions in 2005 versus gains on foreign exchange transactions in
2004.  Other (expense) income approximated $140,000 and $(24,000) for the
three months ended September 30, 2005 and 2004, respectively.  The
improvement is attributable primarily to higher gains on foreign exchange
transactions in 2005.

Income Taxes.  The effective tax rate approximated 26.4% and 67.4% for
the nine months ended September 30, 2005 and 2004, respectively, and
31.6% and (12.3%) for the three months ended September 30, 2005 and 2004,
respectively.  The decrease is attributable principally to profitability
of the U.K. operations in 2005 for which no tax liability arises due to
utilization of net operating loss carryforwards and beneficial permanent
deductions in comparison to losses by the U.K. operations in the prior
year for which no tax benefit was recognized since it was more likely
than not the resulting asset would not be realized.


                                 - 18 -


Net Income (Loss).  As a result of the above, the Corporation's net
income (loss) for the nine months ended September 30, 2005 and 2004
equaled $6,759,000 and $467,000, respectively, and $2,109,000 and
$(1,780,000), respectively, for the three months ended September 30, 2005
and 2004.

Liquidity and Capital Resources

Net cash flows provided by operating activities approximated $2,004,000
and $7,877,000 for the nine months ended September 30, 2005 and 2004,
respectively. The decrease is attributable primarily to an increase in
accounts receivable arising from higher sales for the third quarter of
2005 versus third quarter of 2004 and a reduction in accounts payable due
primarily to timing of payments.

Net cash flows used in investing activities were $(7,342,000) and
$(9,969,000) for the nine months ended September 30, 2005 and 2004,
respectively.  The change is attributable to a reduction in net purchases
of short-term marketable securities and lower capital expenditures.
Capital expenditures approximated $3,206,000 for the nine months ended
September 30, 2005 and $5,251,000 for the nine months ended September 30,
2004 of which approximately $923,000 of U.K. governmental grants were
received during the same period reducing the net cost of the
expenditures.  Additionally, the remaining sales proceeds of $500,000
from the 2003 sale of the Plastic Processing Machinery segment were
received in 2004. As of September 30, 2005, future capital expenditures
totaling $3,696,000 have been approved.  Funds on-hand and funds
generated by future operations are expected to be sufficient to finance
capital expenditure requirements.

Net cash flows used in financing activities were $(2,749,000) and
$(2,186,000) for the nine months ended September 30, 2005 and 2004,
respectively. Dividends were paid at a rate of $0.30 per share for each
of the nine month periods.  Issuance of stock under the Corporation's
stock option plan provided cash of $178,000 and $722,000 for the
respective nine month periods.

The change in the value of local currencies against the dollar,
principally the British pound, impacted cash and cash equivalents by
$203,000 and $(212,000) for the nine months ended September 30, 2005 and
2004.

The Corporation maintains short-term lines of credit and an overdraft
facility in excess of the cash needs of its businesses.  The total
available at September 30, 2005 was approximately $8,200,000 (including
2,100,000 GBP in the U.K. and 400,000 Euros in Belgium).

statements are identified by the use of the words "believe," "expect,"
"anticipate," "estimate," "projects," "forecasts" and other expressions
that indicate future events and trends. Forward-looking statements speak
only as of the date on which such statements are made, are not guarantees
of future performance or expectations and involve risks and
uncertainties.  In addition, there may be events in the future that the
Corporation is not able to accurately predict or control which may cause
actual results to differ materially from expectations expressed or
implied by forward-looking statements. The Corporation undertakes no
obligation to update any forward-looking statement, whether as a result
of new information, events or otherwise. These forward-looking statements
shall not be deemed incorporated by reference by any general statement

   ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in the Corporation's exposure to market
risk from December 31, 2004.

                    ITEM 4 - CONTROLS AND PROCEDURES

(a) Disclosure controls and procedures. An evaluation of the
effectiveness of the Corporation's disclosure controls and procedures as
of the end of the period covered by this report was carried out under the
supervision, and with the participation, of the management, including the
principal executive officer and principal financial officer.  Disclosure
controls and procedures are defined under Securities and Exchange
Commission ("SEC") rules as controls and other procedures that are
designed to ensure that information required to be disclosed by a company
in reports that it files under the Exchange Act are recorded, processed,
summarized and reported within the required time periods. Based on that
evaluation, the Corporation's management, including the principal
executive officer and principal financial officer, have concluded that
the Corporation's disclosure controls and procedures were effective as of
September 30, 2005.

(c) Changes in internal control over financial reporting. During the
quarter ended September 30, 2005, there have been no changes in our
internal control over financial reporting that have materially affected,
or are reasonably likely to materially affect, our internal control over
financial reporting.
