Note E - Goodwill and Intangible Assets
         ------------------------------

As of June 30, 2001, the Company had goodwill and other intangible
assets, net of accumulated amortization, of $33.3 million, which was
subject to the transitional assessment provisions of Statement of
Financial Accounting Standards (SFAS) No. 142.  A discounted cash flow
model was used to determine the fair value of the reporting units for
purposes of testing goodwill for impairment.  The discount rate used was
based on a risk-adjusted weighted average cost of capital for the
Company.  The Company completed its impairment test of goodwill prior to
December 31, 2001.  The results of this test indicated that the Company's
goodwill was not impaired as of     July 1, 2001, and, therefore, no
impairment loss was recorded.

The Company completed a discounted cash flow and comparable market
capitalization analysis by identified reporting units of the Company
which have recorded goodwill as of June 30, 2003 and 2002.  Based on the
results of these analyses, the Company's goodwill was not impaired as of
June 30, 2003 or 2002.

The gross carrying amount and accumulated amortization of the Company's
intangible assets other than goodwill as of September 30, 2003 and June
30, 2003 were as follows ($000):

Amortization expense recorded on the intangible assets for the three
months ended September 30, 2003 and 2002 was $131,000 and $85,000,
respectively.  Included in the gross carrying amount and accumulated
amortization of the Company's customer lists component of intangible
assets is the effect of the foreign currency remeasurement of the portion
relating to the Company's German distributor.  At September 30, 2003, the
estimated amortization expense for existing intangible assets for each of
the five succeeding fiscal years is as follows ($000):

Note I  - Segment Reporting
          -----------------

The Company reports its segments using the "management approach" model
for segment reporting.  The management approach model is based on the way
a company's management organizes segments within the company for making
operating decisions and assessing performance.  Reportable segments are
based on products and services, geography, legal structure, management
structure or any other manner in which management segregates a company.

The Company's reportable segments offer similar products to different
target markets.  The segments are managed separately due to the
production requirements and facilities that are unique to each segment.
The Company has the following reportable segments: Infrared Optics, which
is the Company's II-VI and Laser Power infrared optics and material
products businesses; Near-Infrared Optics, which is the Company's VLOC
subsidiary; and Military Infrared Optics, which is the Company's Exotic
Electro-Optics subsidiary.  The "Other" category is primarily the
aggregation of the Company's eV PRODUCTS division, the Company's Wide
Bandgap (WBG) Materials group, the Company's corporate research and
development group and remaining corporate activities.

The Infrared Optics segment is divided into the geographic locations in
the United States, Singapore, China, Germany, Japan, Belgium and the
United Kingdom.  Each geographic location is directed by a general
manager and is further divided into production and administrative units
that are directed by managers.  The Infrared Optics segment designs,
manufactures and markets optical and electro-optical components and
materials sold under the     II-VI and Laser Power brand names and used
primarily in high-power CO2 lasers.

The Near-Infrared Optics segment is located in the United States.  The
Near-Infrared Optics segment is directed by a general manager.  The Near-
Infrared Optics segment is further divided into production and
administrative units that are directed by managers.  The Near-Infrared
Optics segment designs, manufactures and markets near-infrared and
visible-light products for industrial, scientific and medical instruments
and laser gain material and products for solid-state YAG and YLF lasers
at the Company's VLOC subsidiary.

The Military Infrared Optics segment is located in the United States.
The Military Infrared Optics segment is directed by a general manager.
The Military Infrared Optics segment is further divided into production
and administrative units that are directed by managers.  The Military
Infrared Optics segment designs, manufactures and markets infrared
products for military applications under the Exotic Electro-Optics brand
name.

All entities comprised in the "Other" category are located in the United
States.  The Company's eV PRODUCTS division manufactures and markets
solid-state x-ray and gamma-ray detection materials and products for use
in medical, security monitoring, industrial, environmental and scientific
applications.  The Company's WBG group manufactures and markets single
crystal silicon carbide substrates for use in solid-state lighting,
wireless infrastructure, RF electronics and power switching industries.

The accounting policies of the segments are the same as those of the
Company.  Substantially all of the Company's corporate expenses are
allocated to the segments.  The Company evaluates segment performance
based upon reported segment earnings or loss, which is defined as
earnings before income taxes, interest and other income or expense.
Inter-segment sales and transfers have been eliminated.

Note J - Derivative Instruments
         ----------------------

SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities", as amended by SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities-Deferral of the effective date of SFAS
No. 133", and SFAS No. 138, "Accounting for Certain Derivative
Instruments and Certain Hedging Activities", were effective for the
Company as of July 1, 2000.  SFAS No. 133 establishes accounting and
reporting standards for derivative instruments and hedging activities.
It requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those
instruments at fair value.  The Company was not required to record any
transition adjustments as a result of adopting these standards.

The Company from time to time purchases foreign currency forward exchange
contracts, primarily in Japanese Yen, that permit it to sell specified
amounts of these foreign currencies expected to be received from its
export sales for pre-established U.S. dollar amounts at specified dates.
These contracts are entered into to limit transactional exposure to
changes in currency exchange rates of export sales transactions in which
settlement will occur in future periods and which otherwise would expose
the Company, on the basis of its aggregate net cash flows in respective
currencies, to foreign currency risk.

The Company recorded the fair value of contracts with a notional amount
of approximately $3.4 million and $2.2 million as of September 30, 2003
and June 30, 2003, respectively.  These amounts were recorded in Other
accrued liabilities as of September 30, 2003 and in Prepaid and other
current assets as of June 30, 2003 on the Consolidated Balance Sheet.
The Company does not account for these contracts as hedges as defined by
SFAS No. 133 and records the change in the fair value of these contracts
in the results of operations as they occur.  The change in the fair value
of these contracts increased (decreased) net earnings by $(137,000) and
$65,000 for the three months ended September 30, 2003 and 2002,
respectively.

To satisfy certain provisions of its credit agreement (see Note F), on
March 6, 2003 the Company entered into a one-year interest rate cap with
a notional amount of $8.8 million replacing an interest rate cap that
expired on March 5, 2003.  These agreements were entered into to limit
interest rate exposure on one-half of the remaining outstanding balance
of the Company's term loan under the credit agreement.  The floating rate
option for the cap agreement is the one-month LIBOR rate with a cap
strike rate of 3.00%.  At September 30, 2003 the one-month LIBOR rate was
1.12%.  The Company has elected not to account for these agreements as
hedges as defined by SFAS No. 133 but instead recorded the unrealized
change in the fair value of these agreements as an increase or decrease
to interest expense in the results of operations.  The effect of the
interest rate cap on net earnings for the three months ended September
30, 2003 was immaterial.

Note K - Stock-Based Compensation
         ------------------------

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-
Based Compensation - Transition and Disclosure."  SFAS No. 148 amends
SFAS No. 123, "Accounting for Stock-Based Compensation," to provide
alternative methods of transition to SFAS No. 123's fair value method of
accounting for stock-based employee compensation should a company elect
this accounting method.  SFAS No. 148 also amends the disclosure
provisions of SFAS No. 123 and Accounting Principles Board (APB) Opinion
No. 28, "Interim Financial Reporting," to require disclosure in the
summary of significant accounting policies of the effects of an entity's
accounting policy with respect to stock-based employee compensation on
reported net income and earnings per share in annual and interim
financial statements.  While SFAS No. 148 does not amend SFAS No. 123 to
require companies to account for employee stock options using the fair
value method, the disclosure provisions of SFAS No. 148 are applicable to
all companies with stock-based employee compensation, regardless of
whether they account for that compensation using the fair value method of
SFAS No. 123 or the intrinsic value method specified in APB Opinion No.
25, "Accounting for Stock Issued to Employees."

The Company uses the intrinsic value approach of APB Opinion No. 25 for
stock options granted to officers and key employees.  All options granted
under the plan had an exercise price equal to the fair market value of
the underlying common stock on the date of grant.

In accordance with the disclosure requirements of SFAS No. 148, the
following pro forma information adjusts previously reported net earnings,
basic earnings per common share and diluted earnings per common share to
reflect the fair value recognition provisions of SFAS No. 123.

Note L - Warranty Reserve
         ----------------

The Company records a warranty reserve as a charge against earnings based
on a percentage of sales utilizing actual returns over the last twelve
months.  If actual returns are not consistent with the historical data
used to calculate these estimates, net sales could either be understated
or overstated.

The following table summarizes the change in the carrying value of the
Company's warranty reserve as of and for the three months ended September
30, 2003 and as of and for the year ended June 30, 2003 ($000).

Note M - New Accounting Pronouncements
         -----------------------------

In January 2003, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 46, "Consolidation of Variable Interest Entities."
Interpretation No. 46 requires unconsolidated variable interest entities
to be consolidated by their primary beneficiaries if the entities do not
effectively disperse the risks and rewards of ownership among their
owners and other parties involved.  The provisions of Interpretation No.
46 are applicable immediately to all variable interest entities created
after January 31, 2003 and variable interest entities in which an
enterprise obtains an interest in after that date, and for variable
interest entities created before this date, the provisions have been
deferred to be effective October 1, 2003.  We are currently evaluating
the provisions of this interpretation; however, we do not believe they
will have a material impact on our accounting for existing investments.


Note N - Acquisition of Certain Coherent Assets
         --------------------------------------

On September 11, 2003, the Company entered into an agreement to acquire
certain assets, equipment, intellectual property and rights from
Coherent, Inc. (Coherent) relating to Coherent's business of growing and
fabricating materials used for ultra-violet (UV) filters.  UV filters
assist aircraft in the early detection of missile threats.  Under the
terms of this asset purchase the Company will pay $2.0 million to
Coherent.  The payment of the purchase price is subject to certain terms
and conditions, including delivery of the equipment and qualification of
materials.  The major assets to be acquired are equipment, inventory and
a patent for crystal growth.  As of September 30, 2003, the Company had
paid $200,000 of the purchase price.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS


Forward-Looking Statements
- --------------------------

This Management's Discussion and Analysis contains forward-looking
statements as defined by Section 21E of the Securities Exchange Act of
1934, as amended, including the statements regarding projected growth
rates, markets, product development, financial position, capital
expenditures and foreign currency exposure.  Forward-looking statements
are also identified by words such as "expects," "anticipates," "intends,"
"plans," "projects" or similar expressions.

Actual results could materially differ from such statements due to the
following factors: materially adverse changes in economic or industry
conditions generally (including capital markets) or in the markets served
by the Company, the development and use of new technology and the actions
of competitors.

There are additional risk factors that could affect the Company's
business, results of operations or financial condition.  Investors are
encouraged to review the risk factors set forth in the Company's most
recent Form 10-K as filed with the Securities and Exchange Commission on
September 26, 2003.


Critical Accounting Policies
- ----------------------------

The preparation of financial statements and related disclosures in
conformity with generally accepted accounting principles and the
Company's discussion and analysis of its financial condition and results
of operations requires the Company's management to make judgments,
assumptions, and estimates that affect the amounts reported in its
consolidated financial statements and accompanying notes.  Note A of the
Notes to Consolidated Financial Statements of the Company's most recent
Form 10-K describes the significant accounting policies and methods used
in the preparation of the Company's consolidated financial statements.
Management bases its estimates on historical experience and on various
other assumptions that it believes to be reasonable under the
circumstances, the results of which form the basis for making judgments
about the carrying values of assets and liabilities.  Actual results may
differ from these estimates.

Management believes the Company's critical accounting policies are those
related to revenue recognition, allowance for doubtful accounts, warranty
reserves, inventory valuation, valuation of long-lived assets including
acquired intangibles and goodwill, accrual of bonus and profit sharing
estimates, accrual of income tax liability estimates and accounting for
stock-based compensation.  Management believes these policies to be
critical because they are both important to the portrayal of the
Company's financial condition and results of operations, and they require
management to make judgments and estimates about matters that are
inherently uncertain.

As of September 30, 2003, there have been no significant changes with
regard to the critical accounting policies disclosed in Management's
Discussion and Analysis in our Annual Report on Form 10-K for the Year
ended June 30, 2003.



                                    -16-




Results of Operations
- ---------------------

Overview

Net earnings for the first quarter of fiscal 2004 were $3,114,000 ($0.21
per share-diluted) on revenues of $34,094,000.  This compares to net
earnings of $2,206,000 ($0.15 per share-diluted) on revenues of
$31,571,000 in the first quarter of fiscal 2003.  The increase of 8% in
revenues for the first quarter of fiscal 2003 compared to the same period
last fiscal year is primarily due to stronger shipments of infrared and
near-infrared optics to both OEM and aftermarket customers.

Bookings for the first quarter of fiscal 2004 remained steady at
$34,582,000 compared to $34,873,000 for the same period last fiscal year.
Infrared and military infrared optics bookings strengthened while near-
infrared optics decreased primarily due to the receipt of a $2.5 million
Yttrium Vanadate research and development bookings recorded in the first
quarter of last fiscal year.  Bookings for contract research and
development for the first quarter of fiscal year 2004 were $1,312,000
compared to $5,390,000 for the same period last fiscal year.  Contract
research and development bookings in the first quarter of the prior
fiscal year included the Title III contract at the Company's Wide Bandgap
group of approximately $2.0 million and the Yttrium Vanadate contract at
the Company's Near-Infrared Optics segment of approximately $2.5 million.
Bookings are defined as customer orders received that are expected to be
converted to revenues over the next twelve months.  For long-term
customer orders, the Company does not include in bookings the portion of
the customer order that is beyond twelve months due to the inherent
uncertainty of an order that far out in the future.

Segment earnings, which is defined as earnings before income taxes,
interest and other income or expense, for the first quarter of fiscal
2004 increased 53% to $4,724,000 compared to $3,086,000 for the same
period last fiscal year primarily due to higher gross margins from
increased manufacturing at our Asian facilities; particularly at our
recently expanded China facility.  Higher sales volume coupled with
manufacturing yield improvements also contributed to the improved segment
earnings.

Bookings, revenues and segment earnings or (loss) for the Company's
reportable segments are discussed below.  See also the segment reporting
discussion in Note I of the notes to consolidated financial statements.

Infrared Optics

Bookings for the first quarter of fiscal 2004 for Infrared Optics
increased 7% to $22,324,000 from $20,768,000 in the first quarter of last
fiscal year.  This increase was attributable in part to an increase in
U.S. OEM orders this fiscal quarter as well as stronger aftermarket order
intake in the current fiscal quarter compared to the last fiscal quarter.
The remaining quarter over quarter improvement was due to stronger order
volume from customers in Japan partially offset by weaker European
activity due to the European vacation period during July and August.
Orders received for laser markings applications continued to gain
momentum during the current fiscal quarter.

Revenues for the first quarter of fiscal 2004 for Infrared Optics
increased 8% to $19,906,000 from $18,354,000 in the first quarter of last
fiscal year.  This increase was primarily attributable to increased
shipment volume for both OEM and aftermarket customers.  The infrared
optics business continues to strengthen as the U.S. and Japan economies
rebound.

Segment earnings for the first quarter increased 29% to $5,451,000 from
$4,231,000 in the first quarter of last fiscal year.  The improvement in
segment earnings for the current fiscal three month period as compared to
the same period of the last fiscal year was due to a combination of
increased sales volume and the increased level of manufacturing at the
Company's Asian facilities in Singapore and China.

Near-Infrared Optics

Bookings for the first quarter of fiscal 2004 for Near-Infrared Optics
decreased 33% to $4,610,000 from $6,900,000 in the first quarter of last
fiscal year.  The decrease was due to the receipt of a large research and



                                    -17-




development contract during the first quarter of last fiscal year.
Commercial bookings for the first quarter of fiscal 2004 in the product
lines used in the medical, semiconductor and defense applications
increased 5% from bookings in the first quarter of last fiscal year.

Revenues for the first quarter for Near-Infrared Optics increased 9% to
$5,951,000 compared to $5,467,000 in the first quarter of last fiscal
year due to increased shipments in the optics and cavities product lines
used in military and semiconductor applications.

Segment earnings for the first quarter of fiscal 2004 increased 50% to
$544,000 from $362,000 in the first quarter of last fiscal year.  This
improvement reflected overall stronger gross margins in both the
commercial and contract research and development areas.

Military Infrared Optics

Bookings for the first quarter of fiscal 2004 for Military Infrared
Optics increased 33% to $6,105,000 as compared to $4,576,000 in the first
quarter of last fiscal year.  The overall increase in bookings was due to
increased domes, windows and other component parts bookings offset by a
decrease in our sapphire product line.  A Javelin missile dome order was
received in the current quarter of which the first twelve months of
anticipated shipments was recorded in accordance with the Company's
bookings policy.  The decrease in the sapphire activity was primarily due
to the IFTS program booked in fiscal year 2003 with no comparable order
in the first quarter of fiscal year 2004.

Revenues for the first quarter of fiscal 2004 for Military Infrared
Optics remained steady at $5,682,000 compared to $5,794,000 in the first
quarter of the last fiscal year.

For the first quarter of fiscal 2004, the Military Infrared Optics
segment incurred a segment loss of $6,000 compared to segment earnings of
$257,000 in the first quarter of the prior fiscal year. The additional
production and development costs incurred during the ramping up of the
sapphire business more than offset the segment earnings that resulted
from the domes, windows and other component parts business.

Other

The Company's Other category includes the combined operations of the
Company's eV PRODUCTS division, the Company's Wide Bandgap Materials
(WBG) group and the Company's corporate research and development group.

Combined bookings for the first quarter of fiscal 2004 from these
operations decreased 41% to $1,543,000 as compared to $2,629,000 in the
first quarter of last fiscal year.  The decrease in bookings was due to
the receipt of the Title III research and development contract awarded to
the WBG group in the first quarter of last fiscal year not recorded in
the current fiscal first quarter.  The decrease was partially offset by
the recording of the first year of a three year U.S. Army research and
development contract awarded to the Company's eV PRODUCTS division.

Revenues for the first quarter from these operations increased 31% to
$2,555,000 compared to $1,956,000 in the first quarter of the last fiscal
year.  The higher revenues are a direct result of the higher shipments of
hand-held spectrometers for Home Land Security applications, the
increased shipments of bone-mineral densitometer detectors and the higher
level of research and development billings by the Company's eV PRODUCTS
division.

The segment loss for the first quarter of fiscal 2004 of $1,265,000
decreased 28% from the segment loss of $1,764,000 in the first quarter of
the prior fiscal year.  The decrease in the loss was primarily a result
of the incremental gross margin on increased revenues of these
operations.

Overall

Manufacturing gross margin, which is defined as net sales less cost of
goods sold, for the first quarter of fiscal 2004 was $13,987,000 or 44%
of revenues compared to $11,122,000 or 38% of revenues for the same



                                    -18-




period last fiscal year.  The increased sales volume for the current
three month period as compared to the same period last fiscal year and
the increase in the amount of manufacturing done at the Company's
Singapore and China facilities impacted gross margins favorably.

Contract research and development gross margin, which is calculated as
contract research and development revenues less expenses, for the first
quarter of fiscal 2004 was $50,000 or 2% of research and development
revenues compared to a gross margin of $118,000 or 5% of research and
development revenues for the same period last fiscal year.  The contract
research and development revenues and costs are a result of development
efforts in the Near-Infrared Optics and the Military Infrared Optics
segments as well as activities in the eV PRODUCTS division and the WBG
group for the current quarter.  The decreased revenues level for the
three month period as compared to the same period last fiscal year is
primarily due to lower contract activity in the Near-Infrared Optics
segment and the WBG group during the current fiscal year.  Contract
research and development gross margin is a result of a blend of cost plus
fixed fee, cost reimbursement and percentage of completion contract
activities.

Company-funded internal research and development expenses for the first
quarter of fiscal 2004 were $1,087,000 compared to $959,000 for the same
period last fiscal year.  Expenses for both periods were 3% of revenues.
The higher expense is primarily the result of lower external contract
support for the Company's efforts in silicon carbide.

Selling, general and administrative expenses for the first quarter of
fiscal 2004 were $8,226,000 or 24% of revenues compared to $7,195,000 or
23% of revenues for the same period last fiscal year.  The dollar and
percentage increases for the quarter as compared to the same period last
fiscal year reflect increased legal and professional fees during the
quarter to defend and protect its trade secrets and intellectual property
(see Note O to the notes to consolidated financial statements).  In
addition to the increase in legal and professional fees, the Company
recorded higher salary expenses as compared to the same quarter last
fiscal year for its worldwide profit driven bonus program.

Interest expense for the first quarter of fiscal 2004 was $134,000
compared to $278,000 for the same period last fiscal year.  The lower
interest expense reflects lower LIBOR based interest rates as well as
lower overall debt levels of the Company at September 30, 2003 as
compared to the same period last fiscal year.

Other income for the first quarter of fiscal 2004 was $91,000 compared to
other income of $114,000 for the same period last fiscal year.  These
income items included foreign currency gains, interest income, royalty
income and other income items.  Other income was partially offset by the
minority interest in II-VI/L.O.T. and other expense items.

The Company's year-to-date effective income tax rate is 33% compared to
an effective income tax rate of 25% for the same period in fiscal 2003.
The increase in the effective tax rate as compared to the effective tax
rate in effect for the previous year is the result of an expected shift
in the mix of taxable earnings to higher tax rate jurisdictions.


Liquidity and Capital Resources
- -------------------------------

In the first three months of fiscal 2004, net cash provided by operating
activities of $2.4 million and cash on hand was used primarily to fund
$2.8 million in property, plant and equipment, and to pay down $1.0
million of debt.  Cash transactions for the first three months of fiscal
2004 plus cash on hand at the beginning of the fiscal year resulted in a
cash position of $14.3 million at September 30, 2003.

The Company had available $15.3 million and $15.5 million under its line
of credit option of the credit facility as of September 30, 2003 and June
30, 2003, respectively.  The Company is obligated on the first day of
each fiscal quarter to pay $1.9 million on the first day of each fiscal
quarter thereafter until the term loan is repaid.  At September 30, 2003,
$15 million remained outstanding on the term loan (see Note F to the
notes to consolidated financial statements).



                                    -19-



The Company believes cash flow from operations, existing cash reserves
and available borrowing capacity will be sufficient to fund its working
capital needs, capital expenditures, scheduled debt payments and internal
growth for fiscal 2004

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK


Foreign Exchange Risks

The Company is exposed to market risks arising from adverse changes in
foreign currency exchange rates and interest rates.  In the normal course
of business, the Company uses a variety of techniques and derivative
financial instruments as part of its overall risk management strategy
primarily focused on its exposure to the Japanese Yen.  No significant
changes have occurred in the techniques and instruments used other than
those described below.

The Company also has transactions denominated in Euros and Pounds
Sterling.  Changes in the foreign currency exchange rates of these
currencies did not have a material impact on the results of operations
for the period ended September 30, 2003.

In the normal course of business, the Company enters into foreign
currency forward exchange contracts with its banks.  The purpose of these
contracts is to hedge ordinary business risks regarding foreign
currencies on product sales.  Foreign currency exchange contracts are
used to limit transactional exposure to changes in currency rates.  The
Company enters into foreign currency forward contracts that permit it to
sell specified amounts of foreign currencies expected to be received from
its export sales for pre-established U.S. dollar amounts at specified
dates.  The forward contracts are denominated in the same foreign
currencies in which export sales are denominated.  These contracts
provide the Company with an economic hedge in which settlement will occur
in future periods and which otherwise would expose the Company to foreign
currency risk.  The Company monitors its positions and the credit ratings
of the parties to these contracts.  While the Company may be exposed to
potential losses due to risk in the event of non-performance by the
counterparties to these financial instruments, it does not anticipate
such losses.  The Company entered into a low interest rate, 300 million
Yen loan with PNC Bank in September 2002 in an effort to minimize the
foreign currency exposure in Japan.  A change in the interest rate of 1%
for this Yen loan would have changed the interest expense by
approximately $7,000 and a 10% change in the Yen to dollar exchange rate
would have changed revenues by approximately $374,000 for the quarter
ended September 30, 2003.

For II-VI Singapore Pte., Ltd. and its subsidiaries, the functional
currency is the U.S. dollar.  Gains and losses on the remeasurement of
the local currency financial statements are included in net earnings.
Foreign currency remeasurement gains were $100,000 and $65,000 for the
quarters ended September 30, 2003 and 2002, respectively.

For all other foreign subsidiaries, the functional currency is the local
currency.  Assets and liabilities of those operations are translated into
U.S. dollars using period-end exchange rate; while income and expenses
are translated using the average exchange rates for the reporting period.
Translation adjustments are recorded as accumulated other comprehensive
income within shareholders' equity.

Interest Rate Risks

On March 6, 2003, the Company entered into an interest rate cap,
replacing an existing interest rate cap that matured on March 5, 2003,
with a notional amount of $8.8 million as required under the terms of its
current credit agreement in order to limit interest rate exposure on one-
half of the then outstanding balance of the term loan.  In the fiscal
quarter ended September 30, 2003, the Company decreased its borrowings by
$0.8 million.  As of September 30, 2003, the total borrowings of $22.9
million include $15.0 million under the term loan option, $4.8 million
under the line of credit option, $2.7 million Japanese Yen loan and a
$0.4 million Pennsylvania Industrial Development Authority (PIDA) term
note.  As such, the Company is exposed to changes in interest rates.  A
change in the interest rate of 1% would have changed the interest expense
by approximately $58,000 for the fiscal quarter ended September 30, 2003.

Item 4.  CONTROLS AND PROCEDURES

As of the end of the period covered by this quarterly report on Form 10-
Q, the Company's management evaluated, with the participation of Carl J.
Johnson, the Company's Chairman and Chief Executive Officer and Craig A.
Creaturo, the Company's Chief Accounting Officer and Treasurer (and
principal financial officer), the effectiveness of the Company's
disclosure controls and procedures (as defined in Exchange Act Rules 13a-
15(e) and 15d-15(e)).  The Company's disclosure controls were designed to
provide reasonable assurance that information required to be disclosed in
reports that we file or submit under the Securities Exchange Act of 1934
is recorded, processed, summarized and reported within the time periods
specified in the rules and forms of the Securities and Exchange
Commission.  It should be noted that the design of any system of controls
is based in part upon certain assumptions about the likelihood of future
events, and there can be no assurance that any design will succeed in
achieving its stated goals under all potential future conditions,
regardless of how remote.  However, the controls have been designed to
provide reasonable assurance of achieving the controls' stated goals.
Based on that evaluation, Messrs. Johnson and Creaturo concluded that the
Company's disclosure controls and procedures are effective at the
reasonable assurance level.  There were no changes in the Company's
internal control over financial reporting that occurred during the
Company's most recent fiscal quarter that have materially affected or are
reasonably likely to materially affect the Company's internal control
over financial reporting.
