             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1.   Basis of Presentation

     The consolidated balance sheet of OYO Geospace Corporation and its
subsidiaries (the "Company") at September 30, 2002 was derived from the
Company's audited consolidated financial statements at that date. The
consolidated balance sheet at March 31, 2003 and the consolidated statements of
operations for the six months ended March 31, 2003 and 2002, and the
consolidated statements of cash flows for the six months ended March 31, 2003
and 2002, were prepared by the Company, without audit. In the opinion of
management, all adjustments, consisting of normal recurring adjustments,
necessary to present fairly the consolidated financial position, results of
operations and cash flows were made. The results of operations for the six
months ended March 31, 2003 are not necessarily indicative of the operating
results for a full year or of future operations.

     Certain information and footnote disclosures normally included in financial
statements presented in accordance with accounting principles generally accepted
in the United States of America were omitted. The accompanying consolidated
financial statements should be read in conjunction with the financial statements
and notes thereto contained in the Company's Annual Report on Form 10-K for the
year ended September 30, 2002.

     Revenue is primarily derived from the sale, and short-term rental under
operating leases, of seismic instruments and equipment and commercial graphics
products. Sales revenues are recognized when title and risk of loss have passed
to the customer, which generally occurs when such products are shipped (when the
revenue cycle is completed). Products are generally sold without any customer
acceptance provisions and the Company's standard terms of sale do not allow its
customers to return products except for manufacturing defects. The Company's
products generally do not require installation assistance or sophisticated
instruction. The Company offers a standard product warranty obligating it to
repair or replace equipment with manufacturing defects. The Company maintains a
reserve for future warranty costs based on historical experience. Rental
revenues are recognized on a straight-line basis as earned over the rental
period. Short-term rentals of the Company's equipment generally range from daily
rentals to rental periods of up to six months.

     The Company expenses research and development costs as incurred.

     The Company records a write-down of its inventory when the cost basis of
any manufactured product (including any estimated future costs to complete the
manufacturing process) exceeds its net realizable value.

Recent Accounting Pronouncements

     In June 2002, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 146, "Accounting for
Costs Associated with Exit or Disposal Activities". This statement revises the
accounting and reporting for costs associated with exit or disposal activities
so as to provide recognition of such costs when a liability is incurred rather
than when the entity commits to an exit plan. SFAS No. 146 is effective for exit
or disposal activities initiated after March 31, 2003. Management does not
believe the adoption of SFAS No. 146 will have a material effect on the
Company's financial position and results of operations.

     In December 2002, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 148, "Accounting for Stock-Based
Compensation and Disclosure - an amendment of FASB Statement No. 123". This
statement amends FASB Statement No. 123, Accounting for Stock-Based
Compensation, to provide alternative transition methods for a voluntary change
to the fair value of accounting for stock-based employee compensation. In
addition, this Statement amends the disclosure requirements of FASB Statement
No. 123 to require more prominent disclosures in both annual and interim
financial statements about the method of accounting for stock-based employee
compensation and the effect of the method used on reported results. See Note 8
for additional disclosures required by SFAS No. 148.

No common share equivalents have been included in the diluted earnings per share

ended March 31, 2003.

7.   Line of Credit

     The Company has entered into a credit agreement pursuant to which it can
borrow up to $10.0 million secured by its accounts receivable and inventory (the
"Credit Agreement"). The Credit Agreement, as amended, expires in January 2004.
Borrowings under the Credit Agreement are subject to borrowing base restrictions
based on (i) consolidated net income plus consolidated interest expense, income
taxes, depreciation and amortization and (ii) levels of eligible accounts
receivable and inventories. The Credit Agreement limits the incurrence of
additional indebtedness, requires the maintenance of certain financial amounts
and contains other covenants customary in agreements of this type. As of March
31, 2003 there were borrowings of $5.7 million outstanding under the Credit
Agreement, and additional borrowings available under the Credit Agreement of
$4.3 million.

     The Company recently amended its Credit Agreement to expire in January
2004. In connection with this amendment, the Company's borrowing interest rate
has become, at the Company's option, the bank's prime rate or a LIBOR based
rate. In addition, the borrowing base restrictions were modified so the Company
could incur additional borrowings up to the maximum limit of $10.0 million. The
Company's borrowing interest rate at March 31, 2003 was 3.8% for its LIBOR-based
borrowings and 4.3% for its prime-based borrowings.

8.  Accounting for Stock-Based Compensation

    At March 31, 2003, the Company had two stock-based employee compensation
plans. The Company accounts for the plans under the recognition and measurement
principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and
related interpretations. No stock-based employee compensation cost is reflected
in net income, as all options granted under those plans had an exercise price
equal to the market value of the underlying common stock on the date of grant.
The following table illustrates the effect on net income and earnings per share
if the Company had applied the fair value recognition provisions of FASB
Statement No. 123, Accounting for Stock-Based Compensation, to stock-based
employee compensation.

9.  Adoption of Accounting Pronouncements

    In July 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets"
("SFAS 142"). Under SFAS 142, goodwill and intangible assets with indefinite
lives are no longer amortized but are reviewed for impairment. Intangible assets
that are not deemed to have indefinite lives will continue to be amortized over
their useful lives; however, no maximum life applies. The Company adopted the
provisions of SFAS 142 effective October 1, 2002. At March 31, 2003, the Company
had goodwill, net of accumulated amortization, of $1.8 million. The adoption of
SFAS No. 142 did not have a material effect on the Company's financial position
or results of operations.

    In August 2001, the Financial Accounting Standards Board issued SFAS No.
143 - "Accounting for Asset Retirement Obligations". This statement requires the
Company to recognize the fair value of a liability associated with the cost the
Company would be obligated to incur in order to retire an asset at some point in
the future. The liability would be recognized in the period in which it is
incurred and can be reasonably estimated. The standard is effective for fiscal
years beginning after June 15, 2002. The Company adopted this standard effective
October 1,

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

2002. The adoption of SFAS No. 143 did not have a material effect on the
Company's financial position or results of operations.

     In October 2001, the Financial Accounting Standards Board issued SFAS No.
144, "Accounting for the Impairment or Disposal of Long Lived Assets". SFAS No.
144 develops an accounting model, based upon the framework established in SFAS
No. 121, for long-lived assets to be disposed of by sales. The accounting model
applies to all long-lived assets, including discontinued operations, and it
replaces the provisions of APB Opinion No. 30, "Reporting Results of
Operations-Reporting the Effects of Disposal of a Segment of a Business and
Extraordinary, Unusual and Infrequently Occurring Events and Transactions", for
disposal of segments of a business. SFAS No. 144 requires long-lived assets held
for disposal to be measured at the lower of carrying amount or fair values less
costs to sell, whether reported in continuing operations or in discontinued
operations. The statement is effective for fiscal years beginning after December
15, 2001. The Company adopted this standard effective October 1, 2002. The
adoption of SFAS No. 144 did not have a material effect on the Company's
financial position or results of operations.

     In April 2002, the Financial Accounting Standards Board issued SFAS No.
145, "Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB
Statement No. 13, and Technical Corrections". This statement clarified guidance
related to the reporting of gains and losses from extinguishment of debt and
resolves inconsistencies related to the required accounting treatment of certain
lease modifications. The provisions of this statement relating to extinguishment
of debt became effective for financial statements issued for fiscal years
beginning after May 15, 2002. The provisions of this statement relating to lease
modification are effective for transactions occurring after May 15, 2002. The
Company adopted this standard effective October 1, 2002. The adoption of SFAS
No. 145 did not have a material effect on the Company's financial position or
results of operations.

     On November 25, 2002, the Financial Accounting Standards Board ("FASB")
issued FASB interpretation No. 45 ("FIN 45"), Guarantor's Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and
Rescission of FASB interpretation No. 34. FIN 45 clarifies the requirements of
FASB Statement No. 5, Accounting for Contingencies (FAS 5), relating to the
guarantor's accounting for, and disclosure of, the issuance of certain types of
guarantees. The Company is implementing the disclosure requirements of this
standard this year and will disclose the measurement and other provisions of FIN
45 in its 2004 fiscal year financial statements. The Company offers a standard
product warranty obligating it to repair or replace equipment with manufacturing
defects. The Company maintains a reserve for future warranty costs based on
historical experience. Changes in the warranty reserve are contained in the
following table (in thousands):

        Balance at the beginning of the period (October 1, 2002) ......  $  841

10.   Film Supplier Developments

     In April 2002, the Company purchased certain intellectual property rights
from its then primary supplier of film (the "Former Primary Film Supplier") for
$2.3 million. Such purchase gave the Company exclusive ownership of all
technology used by the Former Primary Film Supplier to manufacture dry thermal
film used in the thermal imaging equipment the Company manufactures. Such
purchase included technology then existing and any dry thermal film technology
thereafter developed by the Former Primary Film Supplier for use in the
Company's equipment. The

                    OYO GEOSPACE CORPORATION AND SUBSIDIARIES

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Company also entered into an amended supply agreement pursuant to which the
Former Primary Film Supplier agreed to provide the Company with the dry thermal
film. In connection with the purchase, the Company agreed to license the
technology to the Former Primary Film Supplier on a perpetual basis so long as
it could meet predefined quality and delivery requirements. If the Former
Primary Film Supplier could not meet such requirements, the Company has the
right to use the technology itself or to license the technology to any third
party to manufacture dry thermal film.

     On July 3, 2002, the Former Primary Film Supplier filed a Chapter 11
reorganization petition in Federal Bankruptcy Court for the Western District of
New York. At the date of such bankruptcy filing, the Company had $3.4 million of
long-term assets carried on its balance sheet as a result of the Company's prior
transactions with the Former Primary Film Supplier (including the $2.3 million
investment in intellectual property acquired from the Former Primary Film
Supplier described above). Around that time, the Former Primary Film Supplier
advised the Company that, in connection with its bankruptcy filing, it was
seeking a buyer for its business that would assume its relationship and
contracts with the Company, and it was the Company's intention to cooperate in
such efforts to the extent its on-going interest could be served thereby. The
Company is no longer optimistic that a buyer can be found to operate the Former
Primary Film Supplier's business.

     Over the past six months, the Former Primary Film Supplier has failed to
meet substantially all of the Company's purchase orders and has ceased to
provide the Company with dry thermal film. As a result, the Company is currently
purchasing a large quantity of dry thermal film from its alternate supplier of
dry thermal film (the "Other Film Supplier") and the Company is using the
technology it purchased from the Former Primary Film Supplier to manufacture dry
thermal film internally.

     As a result of the bankruptcy filing by the Former Primary Film Supplier,
the Company recorded a charge in its third quarter of fiscal year 2002 of
approximately $1.2 million due to the ultimate uncertainty of realization of
value on certain assets, particularly certain prepaid purchase benefits and
similar benefits under the amended supply agreement with the Former Primary Film
Supplier. The Company does not believe there has been any impairment in the
value of the intellectual property it acquired from the Former Primary Film
Supplier because of its ability to utilize the intellectual property to have
thermal film manufactured internally or possibly elsewhere.

     No claims have been made against the Company or by the Company at present
in connection with the Former Primary Film Supplier's bankruptcy, except that on
December 10, 2002, the Company received a notice of claim for alleged
preferential payments made by the Former Primary Film Supplier to the Company in
the period before filing of the bankruptcy proceeding in the approximate amount
of $260,000. The Company intends to vigorously defend against such claim under
the overall circumstances of its relationship with the Former Primary Film
Supplier. At present, the Company does not know whether it will make any claims
against the Former Primary Film Supplier and it is unable to predict whether any
additional claims will be made against the Company in connection with the Former
Primary Film Supplier's bankruptcy proceeding as to any aspect of its
relationship with the Former Primary Film Supplier. The Company is unable at
this time to predict the outcome and effects of this still developing situation.
The Company has, nevertheless, made provision for existing claims that it
believes are adequate at this time, although it is unable to make such
predictions with any certainty.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

    The following analysis of the financial condition and results of operations
of OYO Geospace Corporation should be read in conjunction with the Consolidated
Financial Statements and Notes related thereto which are included elsewhere in
this Form 10-Q.

Industry Overview

    We design and manufacture instruments and equipment used in the acquisition
and processing of seismic data. We have been in the seismic instrument and
equipment business since 1980, marketing our products primarily to the oil and
gas industry worldwide. We also design and manufacture thermal imaging equipment
and distribute dry thermal film products to the commercial graphics industry. We
have been serving the commercial graphics industry since 1995.

Seismic Industry

    Geoscientists use seismic data to map potential or existing oil and gas
bearing formations and the geologic structures that surround them. Seismic data
is used primarily in connection with the exploration, development and production
of oil and gas.

    Seismic data acquisition is conducted on land by combining a seismic energy
source and a data recording system. The energy source imparts seismic waves into
the earth, reflections of which are received and measured by geophones and
hydrophones. Electrical signals generated by the geophones and hydrophones are
simultaneously transmitted through leader wire, geophone and hydrophone string
connectors and telemetric cable to data collection units, which store
information for processing and analysis. Seismic thermal imaging output devices
are used in the field or office to create a graphic representation of the
seismic data after it has been acquired.

    Marine seismic data acquisition is conducted primarily by large ocean-going
vessels that tow long seismic cables known as "streamers". Usually, the energy
source in marine seismic data acquisition is an airgun, and the reflected
seismic waves are received and measured by hydrophones, which are an integral
part of the streamers. The streamers simultaneously transmit the electrical
impulses back to the vessel via telemetric cable included within the streamers,
and the seismic data is recorded and processed in much the same manner as it is
on land.

    An estimated one to two-thirds of the reserves found with every oil and gas
discovery will be left behind in the reservoir, not recoverable economically or
at times even identified. Reservoir characterization and management programs, in
which the reservoir is carefully imaged and monitored throughout its economic
life by seismic instruments and equipment, are now seen as vital tools for
improving production recovery rates. Seismic surveys repeated over selected time
intervals show dynamic changes within the reservoir and can be used to monitor
the effects of production. We expect to incur significant future research and
development expenditures aimed at the development of additional seismic
acquisition products and services used for high definition reservoir
characterization for use in both land and marine environments.

    While orders for our products can vary substantially from quarter to
quarter, reservoir characterization projects, especially deepwater projects,
require the use of more equipment over a longer period of time than is required
by conventional surface seismic systems. Revenue recognition in accordance with
generally accepted accounting principles for these large-scale projects has the
potential to result in substantial fluctuations in our quarterly performance.
These variations may impact our operating results and cash flow, manufacturing
capability and expense levels in any given quarter. Furthermore, because of the
scale and nature of reservoir characterization projects, there may be delays in
their implementation and uncertainties about their final course. As a result, we
are unable at present to predict the impact of any such projects on our
business, financial condition and results of operations.

Commercial Graphics Industry

     Our entry into the commercial graphics business segment occurred in 1995 as
we leveraged our thermal imaging equipment technology, originally designed for
seismic data processing applications, into new markets. With minor product
modifications, we were successful in adapting these products for use in the
commercial graphics industry.

     Our commercial graphics business segment manufactures and sells thermal
imaging equipment and dry thermal film primarily to the screen print, point of
sale, signage and textile market sectors. Our thermal imaging equipment is
capable of producing data images ranging in size from 12 to 54 inches wide, with
resolution ranging from 400 to 1,200 dpi (dots per inch). This business segment
has some sales to customers in the seismic industry.

     In April 2002, we purchased certain intellectual property rights from our
then primary supplier of film (the "Former Primary Film Supplier") for $2.3
million. Such purchase gave us exclusive ownership of all technology used by the
Former Primary Film Supplier to manufacture dry thermal film used in the thermal
imaging equipment we manufacture. Such purchase included technology then
existing and any dry thermal film technology thereafter developed by the Former
Primary Film Supplier for use in our equipment. We also entered into an amended
supply agreement pursuant to which the Former Primary Film Supplier agreed to
provide us with the dry thermal film. In connection with the purchase, we agreed
to license the technology to the Former Primary Film Supplier on a perpetual
basis so long as it could meet predefined quality and delivery requirements. If
the Former Primary Film Supplier could not meet such requirements, the agreement
provides us with the right to use the technology ourselves or to license the
technology to any third party to manufacture dry thermal film.

     On July 3, 2002, the Former Primary Film Supplier filed a Chapter 11
reorganization petition in Federal Bankruptcy Court for the Western District of
New York. At the date of such bankruptcy filing, we had $3.4 million of
long-term assets carried on our balance sheet as a result of the prior
transactions with the Former Primary Film Supplier (including the $2.3 million
investment in intellectual property acquired from the Former Primary Film
Supplier described above). The Former Primary Film Supplier advised us that, in
connection with its bankruptcy filing, it was seeking a buyer for its business
that would assume its relationship and contracts with us, and it was our
intention to cooperate in such efforts to the extent our on-going interest could
be served thereby. We are no longer optimistic that a buyer can be found to
operate the Former Primary Film Supplier's business.

     Over the past six months, the Former Primary Film Supplier has failed to
meet substantially all of our purchase orders and has ceased to provide us with
film. As a result, we are currently purchasing a large quantity of dry thermal
film from the Other Film Supplier and we are using the technology we purchased
from the Former Primary Film Supplier to manufacture dry thermal film
internally.

     As a result of the bankruptcy filing by the Former Primary Film Supplier,
we recorded a charge in our third quarter of fiscal year 2002 of approximately
$1.2 million due to the ultimate uncertainty of realization of value on certain
assets, particularly certain prepaid purchase benefits and similar benefits
under the amended supply agreement with the Former Primary Film Supplier. We do
not believe there has been any impairment in the value of the intellectual
property we acquired from the Former Primary Film Supplier because of our
ability to utilize the intellectual property to have thermal film manufactured
internally or possibly elsewhere.

     No claims have been made against us or by us at present in connection with
the Former Primary Film Supplier's bankruptcy, except that on December 10, 2002,
we received a notice of claim for alleged preferential payments made by the
Former Primary Film Supplier to us in the period before filing of the bankruptcy
proceeding in the approximate amount of $260,000. We intend to vigorously defend
against such claim under the overall circumstances of our relationship with the
Former Primary Film Supplier. At present we do not know whether we will make any
claims against the Former Primary Film Supplier and we are unable to predict
whether any additional claims will be made against us in connection with the
Former Primary Film Supplier's bankruptcy proceeding as to any aspect of our
relationship with such Former Primary Film Supplier. We are unable at this time
to predict the outcome and effects of this still developing situation. We have,
nevertheless, made provision for existing claims that we believe are adequate at
this time, although we are unable to make such predictions with any certainty.

Overview

Three and six months ended March 31, 2003 compared to three and six months ended
March 31, 2002.

     Consolidated sales for the three months ended March 31, 2003 increased $2.7
million, or 19.4%, from the corresponding period of the prior fiscal year. The
increase in sales was due to increased sales of our deepwater reservoir
characterization products, increased demand for our Canadian rental products and
new sales of our new offshore cable products targeted at non-seismic
applications. These revenue increases were partially offset by a decline in
demand for our marine-based seismic products and commercial graphics products.
Consolidated sales for the six months ended March 31, 2003 decreased $0.2
million, or 0.6%, from the corresponding period of the prior fiscal year. The
decline was primarily due to a decline in the demand for our traditional
land-based and marine-based seismic products as well as our commercial graphic
products. These declines were partially offset by increased revenues from our
deepwater reservoir characterization products and from our Canadian rental
products. We expect the market for our traditional land and marine-based seismic
products to remain weak in the near term due to continued industry weakness, and
as the Canadian winter equipment rental season comes to an end. However, we also
expect continued growth and acceptance of our new deepwater reservoir
characterization and offshore cable products, although we cannot predict the
exact timing thereof or the periods in which we will specifically see growth and
acceptance.

     Consolidated gross profits for the three and six months ended March 31,
2003 decreased by $0.3 million, or 5.3% and $2.0 million, or 22.3%,
respectively, from the corresponding periods of the prior year. The lower gross
profits and gross profit margins resulted from lower sales of our marine-based
seismic products and commercial graphics products, both of which generally yield
higher gross profit margins. These lower sales levels were partially offset by
higher gross margins from sales of our new reservoir products. Competitive
pricing pressures resulting from manufacturing over-capacity and the
under-absorption of fixed manufacturing costs are expected to continue to have
an unfavorable impact upon the gross profit margins we realize from sales of our
land-based seismic products.

     Consolidated operating expenses for the three months ended March 31, 2003
decreased $0.2 million, or 3.3%, from the corresponding period of the prior
fiscal year. Consolidated operating expenses for the six months ended

                                       15

<PAGE>

March 31, 2003 increased $0.1 million, or 1.2%, from the corresponding period of
the prior fiscal year. The small decrease in operating expenses in the most
recent quarter is the result of our initial action to reduce operating costs in
response to current market conditions. We intend to undertake additional
cost-cutting actions in the near future to reorganize our business operations in
an effort to more efficiently serve our customers.

     The estimated effective tax rate for the three months and six months ended
March 31, 2003 was 31.2% and 32.0%, respectively. The estimated effective tax
rate for the three months and six months ended March 31, 2002 was an 81.0% and
76.7%, respectively. The tax provision for the prior year periods included a
benefit of $60,000 and $57,000, respectively, related to a change in estimate of
our fiscal 2001 year-end tax accrual to the subsequently filed United States tax
return.

Seismic

     Our seismic product lines currently consist of geophones and hydrophones,
including multi-component geophones and hydrophones, seismic leader wire,
geophone string connectors, seismic telemetry cable, high definition reservoir
characterization products and services, marine seismic cable retrieval devices
and small data acquisition systems targeted at niche markets.

Revenue

     Sales of our seismic products for the three months ended March 31, 2003
increased $3.5 million, or 34.2%, from the corresponding period of the prior
fiscal year due to strong demand for our reservoir and rental products, as well
as increased sales of consumable land-based parts and accessories. These sales
were offset by a significant decline in our marine-based products. Sales of our
seismic products for the six months ended March 31, 2003 increased $0.6 million,
or 2.8%, respectively, from the corresponding period of the prior fiscal year.
The improvement was primarily due to increased sales of our reservoir and rental
products offset by a decline in the demand for our marine-based products.

Operating Income

     Operating income for the three months ended March 31, 2003 increased $0.7
million, or 104.3%, from the corresponding period of the previous fiscal year.
The increase in operating income is generally attributable to the profits
realized from the sale of our deepwater reservoir characterization products as
well as additional profits earned from rental of our geophone products in
Canada, partially offset by a decline in the profits earned from sales of our
marine-based products. Operating income for the six months ended March 31, 2003
decreased $1.0 million, or 78.9%, from the corresponding period of the prior
fiscal year. The decrease in operating income primarily resulted from decreased
gross profits associated with lower sales levels of our marine-based products,
partially offset by increased profits realized from the sale of our deepwater
reservoir characterization products and rental revenues in Canada.

Commercial Graphics

     Our commercial graphics business segment manufactures and sells thermal
imaging equipment and dry thermal film primarily to the screen print, point of
sale, signage and textile market sectors. This business segment has some sales
to customers in the seismic industry.

Revenue

     Sales of our commercial graphics products for the three months and six
months ended March 31, 2003 decreased $0.8 million, or 20.5% and $0.7 million or
11.1%, respectively, from the corresponding period of the prior year. The
decrease in sales primarily resulted from a decline in equipment and accessories
sales.

<PAGE>

Operating Income (Loss)

     Our operating loss for the three months ended March 31, 2003 was $0.2
million, a reduction of $0.9 million or 135.1%, from the corresponding period of
the prior fiscal year. Our operating loss for six months ended March 31, 2003
was $0.3 million, a decrease of $1.3 million, or 131.7% from the corresponding
period of the prior year. The reduction in operating income primarily resulted
from (i) increased manufacturing and operating costs associated with the
self-manufacture of dry thermal film, (ii) increased research and development
expenses associated with a newly introduced 1200 dpi thermal imaging device, and
(iii) increased amortization expenses resulting from the $2.3 million purchase
of intellectual property in April 2002. Such intellectual property is being
amortized on a straight basis over five years.

Liquidity and Capital Resources

     At March 31, 2003, we had $0.2 million in cash and cash equivalents. For
the six months ended March 31, 2003, we used approximately $4.5 million of cash
in operating activities principally resulting from our net loss of $1.3
million, adding back depreciation and amortization of $2.1 million, less the
impact of $2.7 million of increased inventories, $0.9 million of increased
accounts and notes receivable, $1.1 million of decreased accounts payable, $0.9
million of decreased income taxes payable and $0.8 million of increased prepaid
expenses. The increase in inventories was primarily as a result of manufacturing
goods for shipment in future periods, including the build-up of thermal film
stocks. Such uses of cash were partially offset by a $0.8 million increase in
accrued expenses and other items.

     For the six months ended March 31, 2003, we used approximately $2.0 million
of cash in investing activities resulting from capital expenditures.

     For the six months ended March 31, 2003, cash from financing activities
increased approximately $5.0 million primarily due to borrowings under our
credit facility.

     We have entered into a credit agreement pursuant to which we can borrow up
to $10.0 million secured by our accounts receivable and inventory (the "Credit
Agreement"). The Credit Agreement, as amended, expires in January 2004.
Borrowings under the Credit Agreement are subject to borrowing base restrictions
based on (i) consolidated net income plus consolidated interest expense, income
taxes, depreciation and amortization and (ii) levels of eligible accounts
receivable and inventories. The Credit Agreement limits the incurrence of
additional indebtedness, requires the maintenance of certain financial amounts
and contains other covenants customary in agreements of this type. As of March
31, 2003 there were borrowings of $5.7 million outstanding under the Credit
Agreement, and additional borrowings available under the Credit Agreement of
$4.3 million.

     We recently amended our Credit Agreement to expire in January 2004. In
connection with this amendment, our borrowing interest rate has become, at our
option, the bank's prime rate or a LIBOR based rate. In addition, the borrowing
base restrictions were modified so the Company could incur additional borrowings
up to the maximum limit of $10.0 million. Our borrowing interest rate at March
31, 2003 was 3.8% for our LIBOR-based borrowings and 4.3% for our prime-based
borrowings.

Critical Accounting Policies

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires the use
of estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. We consider many factors in selecting
appropriate operational and financial accounting policies and controls and in
developing the estimates and assumptions that are used in the preparation of
these financial statements. We continually evaluate our estimates, including
those related to bad debts reserves, inventory obsolescence reserves,
self-insurance reserves, product warranty reserves, intangible assets and
deferred income tax assets. We base our estimates on historical experience and
various other factors that are believed to be reasonable under the
circumstances. Actual results may differ from these estimates under different
conditions or assumptions.

                                       17

<PAGE>

     Revenue is primarily derived from the sale, and short-term rental under
operating leases, of seismic instruments and equipment and commercial graphics
products. Sales revenues are generally recognized when our products are shipped
and title and risk of loss have passed to the customer. Rental revenues are
recognized as earned over the rental period. Short-term rentals of our equipment
generally range from daily rentals to rental periods of up to six months.
Products are generally sold without any customer acceptance provisions and our
standard terms of sale do not allow customers to return products. Our products
generally do not require installation assistance or sophisticated instruction.
We offer a standard product warranty obligating us to repair or replace
equipment with manufacturing defects. We maintain a reserve for future warranty
costs based on historical experience. We record a write-down of inventory when
the cost basis of any manufactured product (including any estimated future costs
to complete the manufacturing process) exceeds its net realizable value.

Accounting Pronouncements

     In July 2001, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other
Intangible Assets" ("SFAS 142"). Under SFAS 142, goodwill and intangible assets
with indefinite lives are no longer amortized but are reviewed for impairment.
Intangible assets that are not deemed to have indefinite lives will continue to
be amortized over their useful lives; however, no maximum life applies. We
adopted the provisions of SFAS 142 effective October 1, 2002. At March 31, 2003,
the Company had goodwill, net of accumulated amortization, of $1.8 million. The
adoption of SFAS No. 142 did not have a material effect on our financial
position or results of operations.

     In August 2001, the Financial Accounting Standards Board issued SFAS No.
143 - "Accounting for Asset Retirement Obligations". This statement requires us
to recognize the fair value of a liability associated with the cost we would be
obligated to incur in order to retire an asset at some point in the future. The
liability would be recognized in the period in which it is incurred and can be
reasonably estimated. The standard is effective for fiscal years beginning after
June 15, 2002. We adopted this standard effective October 1, 2002. The adoption
of SFAS No. 143 did not have a material effect on our financial position or
results of operations.

     In October 2001, the Financial Accounting Standards Board issued SFAS No.
144, "Accounting for the Impairment or Disposal of Long Lived Assets". SFAS No.
144 develops an accounting model, based upon the framework established in SFAS
No. 121, for long-lived assets to be disposed of by sales. The accounting model
applies to all long-lived assets, including discontinued operations, and it
replaces the provisions of APB Opinion No. 30, "Reporting Results of
Operations-Reporting the Effects of Disposal of a Segment of a Business and
Extraordinary, Unusual and Infrequently Occurring Events and Transactions", for
disposal of segments of a business. SFAS No. 144 requires long-lived assets held
for disposal to be measured at the lower of carrying amount or fair values less
costs to sell, whether reported in continuing operations or in discontinued
operations. The statement is effective for fiscal years beginning after December
15, 2001. We adopted this standard effective October 1, 2002. The adoption of
SFAS No. 144 did not have a material effect on our financial position or results
of operations.

     In April 2002, the Financial Accounting Standards Board issued SFAS No.
145, "Rescission of FASB Statement No. 4, 44, and 64, Amendment of FASB
Statement No. 13, and Technical Corrections". This statement clarified guidance
related to the reporting of gains and losses from extinguishment of debt and
resolves inconsistencies related to the required accounting treatment of certain
lease modifications. The provisions of this statement relating to extinguishment
of debt became effective for financial statements issued for fiscal years
beginning after May 15, 2002. The provisions of this statement relating to lease
modification are effective for transactions occurring after May 15, 2002. We
adopted this standard effective October 1, 2002. The adoption of SFAS No. 145
did not have a material effect on our financial position or results of
operations.

     In June 2002, the Financial Accounting Standards Board issued SFAS No. 146,
"Accounting for Costs Associated with Exit or Disposal Activities". This
statement revises the accounting and reporting for costs associated with exit or
disposal activities so as to provide recognition of such costs when a liability
is incurred rather than when the entity commits to an exit plan. SFAS No. 146 is
effective for exit or disposal activities initiated after March 31, 2003. We do
not believe the adoption of SFAS No. 146 will have a material effect on our
financial position or results of operations.

     In December 2002, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 148, "Accounting for Stock-Based
Compensation and Disclosure - an amendment of FASB Statement No. 123". This
statement amends FASB Statement No. 123, Accounting for Stock-Based
Compensation, to provide alternative transition methods for a voluntary change
to the fair value of accounting for stock-based employee compensation. In
addition, this Statement amends the disclosure requirements of FASB Statement
No. 123 to require more prominent disclosures in both annual and interim
financial statements about the method of accounting for stock-based employee
compensation and the effect of the method used on reported results. See Note 8
to the Consolidated Financial Statements for additional disclosures under SFAS
No. 148.

     On November 25, 2002, the Financial Accounting Standards Board ("FASB")
issued FASB interpretation No. 45 ("FIN 45"), Guarantor's Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and
Rescission of FASB interpretation No. 34. FIN 45 clarifies the requirements of
FASB Statement No. 5, Accounting for Contingencies (FAS 5), relating to the
guarantor's accounting for, and disclosure of, the issuance of certain types of
guarantees. The Company is implementing the disclosure requirements of this
standard this year and will disclose the measurement and other provisions of FIN
45 in its 2004 fiscal year financial statements; this disclosure has been
included in Note 9 to the Consolidated Financial Statements. Our Company offers
a standard product warranty obligating us to repair or replace equipment with
manufacturing defects. We maintain a reserve for future warranty costs based on
historical experience.

Forward Looking Statements and Risks

     Certain of the statements we make in this document and in documents
incorporated by reference herein, including those made under the caption
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," are forward-looking statements for purposes of the Securities Act
of 1933 and the Securities Exchange Act of 1934. Such statements include
projections of our expectations regarding our future capital expenditures,
product lines, growth of product markets and other statements that relate to
future events or circumstances. These statements are subject to known and
unknown risks, uncertainties and other factors that may cause our actual
results, performance or achievements to differ materially from the future
results, performance or achievements expressed or implied by such
forward-looking statements, including the risks and factors described below. You
are cautioned to consider the following factors and risks in connection with
evaluating any such forward-looking statements or otherwise evaluating an
investment in our company.

Our New Products May Not Achieve Market Acceptance.

     In recent years, we have incurred significant expenditures to fund our
research and development efforts and we intend to continue those expenditures in
the future. However, research and development is by its nature speculative, and
we cannot assure you that these expenditures will result in the development of
new products or services or that any new products and services we have developed
recently or may develop in the future will be commercially marketable or
profitable to us.

     In particular, we have incurred substantial expenditures to develop our
recently introduced HDSeis(TM) product line for borehole and reservoir
characterization applications. We cannot assure you that we will realize our
expectations regarding market acceptance and revenues from these products and
services.

A Decline in Industry Conditions Could Affect our Projected Results.

     Any unexpected material changes in oil and gas prices or other market
trends that would impact seismic exploration activity would likely affect the
forward-looking information contained in this document. In addition, the oil and
gas industry is extremely volatile and seismic activity is subject to change
based on political and economic factors outside of our control. In fact, our
results for fiscal year 2002, and results from our land-based seismic activity
in particular, were materially and adversely affected by the downturn in the
industry particularly as the industry continues to limit exploration activities.

                                       19

<PAGE>

     Our estimates as to future results and industry trends, to the extent
described in this document, are generally based on assumptions regarding the
future level of seismic exploration activity and seismic reservoir monitoring
projects and, in turn, their effect on the demand and pricing of our products
and services. In analyzing the market and its impact on us, we have the
following outlook for fiscal year 2003:

       .  The impact of political conditions and hostilities around the world
          including those of the Middle East, which may have a significant
          impact on the oil and gas prices, will not cause a significant
          increase or further significant decrease in demand for our seismic
          products during fiscal 2003.

       .  On the other hand, political conditions and hostilities around the
          world, which have a significant impact on the oil and gas industry,
          will remain and present serious economic risks.

       .  Customer consolidations, the ample supply of seismic data stored in
          libraries, and overall industry weakness will cause demand for our
          traditional land-based seismic products to remain at or below fiscal
          year 2002 levels.

       .  Demand for our land and marine-based seismic products in Russia and
          China is expected to increase over fiscal year 2002 levels, although
          the spread of a contagious disease in China is adding significant
          uncertainty to the Chinese economy (and perhaps the world-wide
          economy) that we are unable to evaluate.

       .  Deep-water marine seismic exploration activity will remain constrained
          and sales of our marine-based products are expected to decline
          significantly in fiscal year 2003.

       .  Our new high definition reservoir characterization products and
          services are expected to become more widely accepted to the industry.
          Sales in fiscal year 2003 are expected to be lower than fiscal year
          2002 levels because fiscal year 2002 included the sale of a $15.8
          million system; a similar delivery of that magnitude is not expected
          based on current backlog and quotations.

       .  Sales of our new offshore cable products are expected to increase in
          fiscal year 2003.

       .  Pricing for many of our land-based seismic products will continue to
          be subject to pressures due to industry-wide manufacturing
          over-capacity.

       .  We will be able to self-manufacture sufficient quantities of dry
          thermal film internally or be able to purchase sufficient quantities
          of dry thermal film from our Other Film Supplier. Demand for our
          products used in the commercial graphics industry is expected to
          increase with continued market acceptance of our dry thermal film and
          new product introductions.

     Our outlook is based on various macro-economic factors, and our internal
assessments, and actual market conditions could vary materially from those
assumed.

We May Experience Fluctuations in Quarterly Results of Operations.

     Historically, the rate of new orders for our products has varied
substantially from quarter to quarter. Moreover, we typically operate, and
expect to continue to operate, on the basis of orders in hand for our products
before we commence substantial manufacturing "runs"; hence, the completion of
orders, particularly large orders for deepwater reservoir characterization
projects, can significantly impact the operating results and cash flow for any
quarter, and results of operations for any one quarter may not be indicative of
results of operations for future quarters.

                                       20

<PAGE>

Our Credit Risks Could Increase as our Customers Continue to Face Difficult
Economic Circumstances.

     We believe and have assumed that our allowance for bad debts at March 31,
2003 is adequate in light of known circumstances. However, we cannot assure you
that additional amounts attributable to uncollectible receivables and bad debt
write-offs will not have a material adverse effect on our future results of
operations. Many of our customers, particularly seismic contractors, have
suffered from lower revenues and experienced liquidity challenges resulting from
the economic difficulties throughout our industry. We have in the past incurred
significant write-offs in our accounts and notes receivable due to customer
credit problems. We have found it necessary from time to time to extend trade
credit to long-term customers and others where risks of non-payment or late
payment exist. Given recent industry conditions, some of our customers are
experiencing liquidity difficulties, which increases those credit risks.

Demand for Our Products is Volatile.

     Demand for our products depends primarily on the level of worldwide oil and
gas exploration activity. That activity, in turn, depends primarily on
prevailing oil and gas prices and availability of seismic data. Historically,
the markets for oil and gas have been volatile, and those markets are likely to
continue to be volatile. Oil and gas prices are subject to wide fluctuation in
response to relatively minor changes in the supply of and demand for oil and
gas, market uncertainty and a variety of additional factors that are beyond our
control. These factors include the level of consumer demand, weather conditions,
domestic and foreign governmental regulations, price and availability of
alternative fuels, political conditions and hostilities in the Middle East and
other significant oil-producing regions, foreign supply of oil and gas, price of
foreign imports and overall economic conditions. Continued low demand for our
products could materially and adversely affect our results of operations and
liquidity.

We Have a Relatively Small Public Float, and Our Stock Price May be Volatile.

     We have approximately 2.4 million shares outstanding held by
non-affiliates. This small float results in a relatively illiquid market for our
common stock. Our average daily trading volume during fiscal year 2002 was
approximately 4,000 shares. Our small float and daily trading volumes has in the
past caused, and may in the future result in, greater volatility of our stock
price.

Our Industry is Characterized by Rapid Technological Development and Product
Obsolescence.

     Our instruments and equipment are constantly undergoing rapid technological
improvement. Our future success depends on our ability to continue to:

       .  improve our existing product lines;
       .  address the increasingly sophisticated needs of our customers;
       .  maintain a reputation for technological leadership;
       .  maintain market acceptance;
       .  anticipate changes in technology and industry standards; and
       .  respond to technological developments on a timely basis.

     Current competitors or new market entrants may develop new technologies,
products or standards that could render our products obsolete. We cannot assure
you that we will be successful in developing and marketing, on a timely and cost
effective basis, product enhancements or new products that respond to
technological developments, that are accepted in the marketplace or that comply
with industry standards.

We Operate in Highly Competitive Markets.

     The markets for our products are highly competitive. Many of our existing
and potential competitors have substantially greater marketing, financial and
technical resources than we do. Additionally, two competitors in our seismic
business segment currently offer a broader range of instruments and equipment
for sale and market this

                                       21

<PAGE>

equipment as "packaged" data acquisition systems. We do not now offer for sale
such a complete "packaged" data acquisition system. Further, certain of our
competitors offer financing arrangements to customers on terms that we may not
be able to match. In addition, new competitors may enter the market and
competition could intensify.

     We cannot assure you that sales of our products will continue at current
volumes or prices if current competitors or new market entrants introduce new
products with better features, performance, price or other characteristics than
our products. Competitive pressures or other factors also may result in
significant price competition that could have a material adverse effect on our
results of operations.

We Have a Limited Market.

     In our seismic business segment, we market our products to contractors and
large, independent and government-owned oil and gas companies. We estimate that,
based on published industry sources, fewer than 30 seismic contracting companies
are currently operating worldwide (excluding those operating in Russia and the
former Soviet Union, India, the People's Republic of China and certain Eastern
European countries, where seismic data acquisition activity is difficult to
verify). We estimate that fewer than ten seismic contractors are engaged in
marine seismic exploration. Due to these market factors, a relatively small
number of customers, some of whom are experiencing financial difficulties, have
accounted for most of our sales. From time to time these seismic contractors
have sought to vertically integrate and acquire our competitors, which has
influenced their supplier decisions before and after such transactions. The loss
of a small number of these customers for whatever reason could materially and
adversely impact our sales.

We Cannot Be Certain of Patent Protection of Our Products.

     We have applied for and hold certain patents relating to our seismic data
acquisition and other products. We also acquired several patents which relate to
the development of dry thermal film from our Former Primary Film Supplier. We
cannot assure you that our patents will prove enforceable, that any patents will
be issued for which we have applied or that competitors will not develop
functionally similar technology outside the protection of any patents we have or
may obtain.

Our Foreign Marketing Efforts Face Additional Risks and Difficulties.

     Net sales outside the United States accounted for approximately 54% of our
net sales during fiscal year 2002. Substantially all of our sales from the
United States are made in U.S. dollars, but from time to time we may make sales
in foreign currencies and may, therefore, be subject to foreign currency
fluctuations on our sales. In addition, net assets reflected on the balance
sheets of our Russian, Canadian and U.K. subsidiaries are subject to currency
fluctuations. Significant foreign currency fluctuations could adversely impact
our results of operations.

     Foreign sales are subject to special risks inherent in doing business
outside of the United States, including the risk of war, terrorist activities,
civil disturbances, embargo and government activities and foreign attitudes
about conducting business activities with United States or Japanese trading
partners, all of which may disrupt markets. Foreign sales are also generally
subject to the risk of compliance with additional laws, including tariff
regulations and import and export restrictions. Sales in certain foreign
countries require prior United States government approval in the form of an
export license. We cannot assure you that we will not experience difficulties in
connection with future foreign sales. Also, should we experience substantial
growth in certain markets, for example Russia, we may not be able to transfer
cash balances to the United States to assist with debt servicing obligations.

We Rely on Key Suppliers for Significant Product Components.

     A Japanese manufacturer unaffiliated with us is currently the only supplier
(the "Japanese Supplier") of wide format thermal printheads that we use to
manufacture our wide format thermal imager equipment. Over the years we have
experienced some quality control issues with such printheads and have returned
significant quantities of these products to the Japanese Supplier for repair,
testing and quality assurance review. We are also aware that the Japanese
Supplier is experiencing financial difficulties and consider it possible that
such supplier may be forced to dispose of or discontinue this line of business.
In this regard, we have publicly available information as to the

                                       22

<PAGE>

Japanese manufacturer that it has incurred significant operating losses in
recent periods. We are not presently experiencing any significant supply or
quality control problems with the Japanese Supplier. However, unforeseen
problems with the Japanese Supplier, if they develop, could have a significant
effect on our ability to meet future production and sales commitments. If the
Japanese Supplier were to discontinue supplying these printheads or was unable
or unwilling to supply printheads in sufficient quantities to meet our
requirements, our ability to compete in the thermal imaging marketplace could be
severely damaged, which could adversely affect our financial performance. We are
not able to evaluate the implications, if any, of that situation at present. We
believe we maintain an adequate inventory of these printheads to continue
production for two to six months.

     Our Former Primary Film Supplier had been the primary supplier of dry
thermal film used by our customers in the thermal imaging equipment we
manufacture. On July 3, 2002, our Primary Film Supplier filed a Chapter 11
reorganization petition in Federal Bankruptcy Court for the Western District of
New York. Around that time, the Former Primary Film Supplier advised us that, in
connection with its bankruptcy filing, it was seeking a buyer for its business
that would assume its relationship and contracts with us. We are no longer
optimistic that a buyer can be found to operate the Former Primary Film
Supplier's business.

     Over the past six months, our Former Primary Film Supplier has failed to
meet substantially all of our purchase orders and has ceased to provide us with
dry thermal film. As a result, we are currently purchasing a large quantity of
dry thermal film from our Other Film Supplier and we are using the technology we
purchased from the Former Primary Film Supplier to manufacture dry thermal film
internally. Except for our Other Film Supplier, we know of no other supplier of
a dry thermal film that performs as well in our thermal imaging equipment.

     If we are unable to economically manufacture dry thermal film internally
using the technology we purchased from our Former Primary Film Supplier or if
our Other Film Supplier was to discontinue supplying dry thermal film or was
unable to supply dry thermal film in sufficient quantities to meet our
requirements, our ability to compete in the thermal imaging marketplace could be
severely damaged, which could adversely affect our financial performance.

We Are Subject to Control by a Principal Stockholder.

     OYO Corporation, a Japanese corporation, owns indirectly in the aggregate
approximately 51.4% of our common stock. Accordingly, OYO Corporation, through
its wholly owned subsidiary OYO Corporation U.S.A., is able to elect all of our
directors and to control our management, operations and affairs. We currently
have, and may continue to have, a variety of contractual relationships with OYO
Corporation and its affiliates.

Our Success Depends Upon A Limited Number of Key Personnel.

     Our success depends on attracting and retaining highly skilled
professionals. A number of our employees are highly skilled engineers and other
professionals. If we fail to continue to attract and retain such professionals,
our ability to compete in the industry could be adversely effected. In addition,
our success depends to a significant extent upon the abilities and efforts of
several members of our senior management.

A Continued General Downturn in the U.S. Economy in 2003 May Adversely Affect
our Business.

     An on-going downturn in the U.S. economy could adversely affect our
business in ways that we cannot yet identify. The current economic downturn may
continue to adversely affect the demand for oil and gas generally and,
therefore, the demand for our services to the oil and gas industry and related
service industry. It could also adversely affect the demand for consumer
products, which could in turn adversely affect our commercial graphics business.
To the extent these factors adversely affect other seismic companies in the
industry, we could see an oversupply of products and services and downward
pressure on pricing for seismic products and services that would adversely
affect us.

Sarbanes-Oxley Act of 2002.

     In response to several high profile cases of accounting irregularities, the
Sarbanes-Oxley Act of 2002 ("the Act") was enacted into law on July 30, 2002.
The Act, and rules promulgated thereunder, as well as new Nasdaq listing
standards addressing corporate governance issues, endeavor to provide greater
accountability and promote investor confidence by requiring more stringent
controls and certifications by corporate management and by impossing new auditor
attestations. The Act affects how audit committees, corporate management and
auditors of publicly traded companies carry out their respective
responsibilities and interact with each other. The Act will likely result in
higher expenses for publicly traded companies as a result of higher audit and
review fees, higher director fees, higher internal costs to document and test
internal controls, higher legal fees and higher director and officer liability
insurance costs. These likely increased expenses may affect smaller public
companies, like us, disporportiantly from their effects on companies with larger
revenue and operating income bases with which to absorb such increased costs.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

     The following discussion of our exposure to various market risks contains
"forward looking statements" that involve risks and uncertainties. These
projected results have been prepared utilizing certain assumptions considered
reasonable in light of information currently available to us. Nevertheless,
because of the inherent unpredictability of foreign currency rates, as well as
other factors, actual results could differ materially from those projected in
this forward looking information.

     We do not have any market risk as to market risk sensitive instruments
entered into for trading purposes and have only very limited risk as to
arrangements entered into other than for trading purposes. Further, we do not
engage in commodity or commodity derivative instrument purchasing or selling
transactions.

Foreign Currency Exchange Rate Risk

     We purchase printheads from OYO Corporation pursuant to terms under which
such purchases are denominated in Japanese yen. We routinely attempt to hedge
our currency exposure on these purchases by entering into foreign currency
forward contracts with a bank. The purpose of entering into these forward hedge
contracts is to eliminate variability of cash flows associated with foreign
currency exposure risk on amounts payable in Japanese yen. Under SFAS No. 133
and related interpretations, our forward contracts with the bank are considered
derivatives. SFAS No. 133 requires that we record these foreign currency forward
contracts on the balance sheet and mark them to fair value at each reporting
date. Our aggregate dollar exposure to forward yen contracts usually does not
exceeded $0.5 million and such contracts ordinarily are settled within 10
months. Resulting gains and losses are reflected in income and were not material
for our fiscal quarter ended March 31, 2003. At March 31, 2003, we had $0.4
million of yen denominated foreign currency forward contracts, and we had $0.4
million of yen denominated accounts payable.

Foreign Currency and Operations Risk

     We have a subsidiary located in Russia. Therefore, our financial results
may be affected by factors such as changes in foreign currency exchange risks,
weak economic conditions or changes in Russia's political climate. Our
consolidated balance sheet at March 31, 2003 reflected approximately $1.4
million of net working capital related to our Russian subsidiary. This
subsidiary both receives its income and pays its expenses primarily in Russian
rubles. To the extent that transactions of this subsidiary are settled in
rubles, a devaluation of the ruble versus the U.S. dollar could reduce any
contribution from our Russian subsidiary to our consolidated results of
operations as reported in U.S. dollars. We do not hedge the market risk with
respect to our operations in Russia; therefore, such risk is a general and
unpredictable risk of future disruptions in the valuation of Russian rubles
versus U.S. dollars to the extent such disruptions result in any reduced
valuation of the Russian subsidiary's net working capital or future
contributions to our consolidated results of operations.

Interest Rate Risk

     We have a revolving line of credit with a bank which subjects us to the
risk of increased interest costs associated with any upward movements in bank
market interest rates. Under the Credit Agreement, as amended, our borrowing
interest rate is either the bank's prime rate or a LIBOR based rate, whichever
we select. As of March 31, 2003, we had borrowed $5.7 million under this Credit
Agreement at an average interest rate of 3.9%. Due to the amount of borrowings
under this credit facility and its short term, we anticipate that any increased
interest costs associated with movements in market interest rates will not be
material to our financial condition, results of operations or cash flows.

                                       25

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

    Within the 90 day period prior to the date of filing this Report on Form
10-Q, our Chief Executive Officer and Chief Financial Officer evaluated the
effectiveness of our disclosure controls and procedures pursuant to Rule 13a-14
under the Securities Exchange Act of 1934. Based upon that evaluation, our Chief
Executive Officer and Chief Financial Officer concluded that our disclosure
controls and procedures are effective.

Changes in Internal Control

    There were no significant changes in our internal controls or in other
factors that could significantly affect our internal controls subsequent to the
date of the evaluation of our disclosure controls and procedures referred to in
the preceding paragraph. While the Company believes that its existing disclosure
controls and procedures have been effective to accomplish these objectives, the
Company intends to continue to examine, refine and formalize its disclosure
controls and procedures and to monitor ongoing developments in this area.
Further, while the Company has confidence in its current internal controls and
procedures for financial reporting, it is continuing to examine such controls in
light of recent a SEC initiative that will require in the future statements by
management and attestation by the Company's independent auditors, as to such
controls.
