1.   BASIS OF PRESENTATION.

          The accompanying consolidated financial statements of Peerless Mfg.
     Co. and Subsidiaries (hereafter referred to as the "Company", "we", "us",
     "our") have been prepared in accordance with accounting principles
     generally accepted in the United States of America for interim financial
     information. The consolidated financial statements of the Company as of
     March 31, 2003, and for the three and nine months ended March 31, 2003 and
     2002 are unaudited and, in the opinion of management, contain all
     adjustments necessary for the fair presentation of the financial position
     and results of operations of the Company for the interim periods. These
     consolidated financial statements should be read in conjunction with the
     financial statements and notes thereto included in the Company's Annual
     Report on Form 10-K for the year ended June 30, 2002. The results of
     operations for the three and nine months ended March 31, 2003 are not
     necessarily indicative of the results to be expected for the entire year
     (see Item 2 - "Management's Discussion and Analysis of Financial Condition
     and Results of Operations - Restructuring and Organizational Realignment"
     and - "Factors That May Affect Our Operating Results and Other Risk
     Factors" following). The Company's fiscal year ends on June 30th.
     References herein to fiscal 2002 and fiscal 2003 refer to our fiscal years
     ended June 30, 2002 and 2003, respectively. Certain fiscal year 2002 items
     have been reclassified to conform with the fiscal year 2003 presentation.
     All dollar and share amounts are in thousands, except per share amounts and
     Notes 9 and 11.

2.   NEW ACCOUNTING STANDARDS.

          In July 2002, the Financial Accounting Standards Board ("FASB") issued
     Statement No. 146, "Accounting for Costs Associated with Exit or Disposal
     Activities." The Statement requires companies to recognize costs associated
     with exit or disposal activities when they are incurred rather than at the
     date of a commitment to an exit or disposal plan. FASB Statement No. 146 is
     to be applied prospectively to exit or disposal activities initiated after
     December 31, 2002. The Company does not expect the adoption of this
     pronouncement to have a material impact on its financial condition or
     results of operations.

          In November 2002, FASB reached a consensus on EITF Issue 00-21,
     "Accounting for Revenue Arrangements with Multiple Deliverables." The
     guidance in this Issue is effective for revenue arrangements entered into
     in fiscal years beginning after June 15, 2003. The Issue addresses certain
     aspects of the accounting by a vendor for arrangements under which it will
     perform multiple revenue-generating activities and whether, as a result,
     there is embedded more than one earnings process for revenue recognition
     purposes. The Company does not expect the adoption of this pronouncement to
     have a material impact on its financial condition or results of operations.

          In November 2002, FASB issued FASB Interpretation ("FIN") No. 45,
     "Guarantor's Accounting and Disclosure Requirements for Guarantees of
     Indebtedness of Others." This Interpretation clarifies the requirements of
     SFAS No. 5, "Accounting for Contingencies," relating to the guarantor's
     accounting for, and disclosure of, the issuance of certain types of
     guarantees. The Interpretation's provision for initial recognition and
     measurement are required on a prospective basis to guarantees issued or
     modified after December 31, 2002. The disclosure requirements are required
     for financial statements of

                       PEERLESS MFG. CO. AND SUBSIDIARIES
                                   FORM 1O-Q
                      FOR THE PERIOD ENDED MARCH 31, 2003


     interim or annual reports that end after December 15, 2002. The Company has
     adopted FIN No. 45 and has included the new disclosure requirements in
     Note 4 - "Product Warranties" to the Notes to the Consolidated Financial
     Statements.

          In January 2003, FASB issued FIN No. 46, "Consolidation of Variable
     Interest Entities." This Interpretation of Accounting Research Bulletin No.
     51, "Consolidated Financial Statements," addresses consolidation by
     business enterprises of variable interest entities which possess certain
     characteristics. The Interpretation requires that if a business enterprise
     has a controlling financial interest in a variable interest entity, the
     assets, liabilities, and results of the activities of the variable interest
     entity must be included in the consolidated financial statements with those
     of the business enterprise. This Interpretation applies immediately to
     variable interest entities created after January 31, 2003 and to variable
     interest entities in which an enterprise obtains an interest after that
     date. The Company did not have any ownership interest in any variable
     interest entities as of March 31, 2003.

          In April 2003, FASB issued Statement No. 149, "Amendment of Statement
     133 on Derivative Instruments and Hedging Activities." FASB Statement No.
     149 requires that contracts with comparable characteristics be accounted
     for similarly. The Statement clarifies the circumstances in which a
     contract with an initial net investment meets the characteristics of a
     derivative, and when a derivative contains a financing component and amends
     certain other existing pronouncements. This Statement is effective for
     contracts entered into or modified after June 30, 2003. The Company does
     not expect the adoption of this pronouncement to have a material impact on
     its financial condition or results of operations.


3.   INVENTORIES.

          Inventories are stated at the lower of cost (first-in, first-out) or

4.   PRODUCT WARRANTIES

          The Company warrants that its products will be free from defects in
     materials and workmanship and will conform to agreed upon specifications at
     the time of delivery and typically for a period of 18 to 36 months from the
     date of customer acceptance, depending upon the specific product and terms
     of the customer agreement. Typical warranties require the Company to repair
     or replace defective products during the warranty period at no cost to the
     customer. The Company attempts to obtain back-up concurrent warranties for
     major component parts from our suppliers. The Company provides for the
     estimated cost of product warranties, based on historical experience by
     product type, expectation of future conditions and the extent of back-up
     concurrent supplier warranties in place, at the time the product revenue is
     recognized. Should these factors, or other factors affecting warranty costs
     differ from our estimates, revisions to the estimated product warranty
     liability are made.

          Product warranty activity for the three months and nine months ended
     March 31, 2003 and 2002, are as follows:

5.   CONTINGENCIES

          Included in the Company's financial statements is a $2.2 million
     receivable due from a customer that recently filed a plan of reorganization
     under Chapter 11 of the United States Bankruptcy Code (original amount of
     the contract was approximately $6.1 million). The Company has been
     classified as an unsecured creditor under such filing. The Company has
     obtained outside counsel to help with the collection of this receivable and
     has filed a statutory lien on the refinery where its equipment was
     installed. In addition, the Company has filed a lawsuit to perfect its lien
     interest against the owner of the refinery. While the Company has reason to
     believe that its lien will be found to be valid, no assurances can be
     given. The Company intends to vigorously pursue its collection and believes
     that this receivable will be collected. In the event that the Company's
     lien is held to be invalid, or if the receivable or a significant portion
     thereof is deemed to be not collectible, the Company will be required to
     write down the receivable to its net realizable value. To the extent that
     the Company's existing allowance for doubtful accounts is not adequate to
     cover this write down, the additional reserve required will be a charge
     against the Company's operating results. See Item 2 - "Management's
     Discussion and Analysis of Financial Condition and Results of Operations -
     Liquidity and Capital Resources" of this Report.

6.   EARNINGS (LOSS) PER SHARE.

          Basic earnings (loss) per share have been computed by dividing net
     earnings (loss) by the weighted average number of common shares outstanding
     during the period. Diluted earnings (loss) per share reflect the potential
     dilution that could occur if options or other contracts to issue common
     shares were exercised or converted into common stock. The following table
     sets forth the computation for basic and diluted earnings (loss) per share
     for the periods indicated.

          The weighted average common shares outstanding-diluted computation
     excluded 190,581 and 198,505 outstanding stock options for the three and
     nine months ended March 31, 2003 because their impact would be
     anti-dilutive. Likewise, the weighted average common shares
     outstanding-diluted computation excluded 60,500 and 24,352 outstanding
     stock options for the three and nine months ended March 31, 2002 because
     their impact would be anti-dilutive.


7.   COMPREHENSIVE INCOME (LOSS).

          Comprehensive income (loss) is defined as all changes in equity during
     a period, except those resulting from investments by owners and
     distributions to owners. The components of comprehensive income (loss) were
     as follows:

8.   STOCK-BASED COMPENSATION

          In December 2002, the Financial Accounting Standards Board (FASB)
     issued Statement of Financial Accounting Standards No. 148, "Accounting for
     Stock-Based Compensation - Transition and Disclosure" (SFAS 148) which
     amends Statement of Financial Accounting Standards No. 123, "Accounting for
     Stock-Based Compensation" (SFAS 123). SFAS 148 provides alternative methods
     of transition for a voluntary change to the fair value based method of
     accounting for stock-based employee compensation and requires disclosures
     in annual and interim financial statements of the effects of stock-based
     compensation as reflected below.

          The Company continues to account for its stock options under the
     recognition and measurement principles of Accounting Principles Board
     Opinion No. 25 "Accounting for Stock Issued to Employees," and related
     Interpretations. No stock based employee compensation expense related to
     the Company's stock options is reflected in the net earnings (loss), as all
     options granted under the plan 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 earnings (loss) and earnings (loss) per
     share if the Company had applied the fair value recognition provisions of
     SFAS 123 to stock-based compensation.

9.   DEFAULT OF CREDIT FACILITY

          The Company maintains a $10 million revolving line of credit facility
     that expires in October 2003. The credit line carries a floating interest
     rate based on the prime or Euros rate plus or minus an applicable margin
     (prime less .25%, Euros plus 2.65%), and is secured by substantially all of
     our assets. The margin factor is subject to a reduction schedule based on
     the Company's attainment of certain financial performance criteria. As of
     March 31, 2003, the Company had no outstanding balances under the credit
     line, and $3.6 million outstanding under letters of credit, leaving us with
     $6.4 million of availability under the facility. The facility contains
     financial covenants, restrictions on capital expenditures, acquisitions,
     asset dispositions, and additional debt, as well as other customary
     covenants.

          The financial covenants, among other things, require that the Company
     not incur losses in three consecutive quarters and that any losses (before
     taxes and extraordinary items) incurred over this period not exceed
     $750,000. The quarter ending March 31, 2003 represents the third
     consecutive quarterly loss for the Company, and for the nine months then
     ended the Company incurred losses (before taxes and extraordinary items) of
     approximately $2.8 million. As such, the Company is in default of its loan
     agreement as of March 31, 2003. The Company has obtained a temporary waiver
     from the bank with respect to this default and anticipates being in
     compliance with the aforementioned covenant upon completion of its fourth
     quarter. However, no assurances can be given that the Company will in fact
     be in compliance with this covenant upon the completion of its fourth
     quarter, or that the bank will be willing to grant further waivers if the
     Company is not in compliance with this covenant upon the completion of its
     fourth quarter, or in the event of further defaults. See Item 2 -
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations - Liquidity and Capital Resources" of this Report.

          On April 22, 2003, the Company closed on the sale of 33 acres of
     undeveloped land located in Wylie, Texas for $575,000. In connection with
     this transaction, the Company will recognize a gain in its results of
     operations for its fourth quarter of fiscal 2003 of approximately $475,000.

12.  SEGMENT INFORMATION

          The Company identifies reportable segments based on management
     responsibility within the corporate structure. The Company has three
     reportable industry segments: SCR Systems, Separation & Filtration and
     Boilers. For a discussion of these various segments, see Item 2 -
     "Management's Discussion and Analysis of Financial Condition and Results of
     Operations - Overview" following.

          Segment profit and loss is based on revenue less direct costs of the
     segment before allocation of general, administrative, research and
     development costs. All inter-company transfers between segments have been
     eliminated. Segment information and reconciliation to operating income
     (loss) for the three and nine months ended March 31, 2003 and 2002 are
     presented below. The Company does not allocate general and administrative
     expenses and restructuring expenses ("unallocated overhead"), assets,
     expenditures for assets or depreciation expense on a segment basis for
     internal management reporting, and therefore such information is not
     presented.

OVERVIEW

     Peerless Mfg. Co. is a global company which provides environmental,
separation & filtration and boiler products for the abatement of air pollution,
the removal of contaminants from gases and liquids, and the production of steam
through its three principal business segments - SCR Systems, Separation &
Filtration and Boilers.

     SCR Systems. In this business segment, our largest, we design, engineer,
manufacture and sell highly specialized environmental control systems, which are
used for air pollution abatement. These systems convert nitrogen oxide (NOx)
emissions from exhaust gases, caused by burning hydrocarbon fuels, such as coal,
gasoline, natural gas and oil, into harmless nitrogen and water vapor. These
systems are totally integrated systems, complete with instruments, controls and
related valves and piping, and are packaged on skids.

     Separation & Filtration. In this business segment, our traditional and
second principal segment, we design, engineer, manufacture and sell specialized
products known as "separators" or "filters" which are used for a variety of
purposes in cleaning gases and liquids as they move through piping systems.
These products are used primarily to remove solid and liquid contaminants from
natural gas and saltwater aerosols from combustion intake air of gas turbine and
diesel engines.

     Boilers. In our third business segment, we design, engineer, manufacture
and sell packaged boilers and other steam generating equipment. This equipment
is used to produce steam used for

heating, drying, driving steam engines and a variety of other applications.
During the first quarter of fiscal 2003, we suspended this business segment. See
"Restructuring and Organizational Realignment" for additional discussion on the
suspension of this business.


RESTRUCTURING AND ORGANIZATIONAL REALIGNMENT

     During the latter part of fiscal 2002, the construction of new merchant
power plants in the United States slowed considerably, as doubts emerged
regarding the actual demand for electricity began to surface, coupled with the
continued weakness in the United States economy. In addition, recent regulatory
uncertainties have caused NOx reduction initiatives relating to retro-fit
projects to be delayed. These factors resulted in a downturn of new SCR Systems
orders during the second half of fiscal 2002, as well as a decrease in new
packaged boiler orders, which impacted our backlog at June 30, 2002.

     In response to the slowdown of new merchant power plants, continued
weakness in the United States and global economies, and recent regulatory and
political uncertainties, in July 2002 we initiated our "restructuring and
organizational realignment initiative." The goal of this initiative was to
reduce costs, streamline operations, and identify and exit certain non-critical,
marginally performing operating activities, thereby positioning us with a more
competitive cost structure vital for our overall long-term success. The plan
included, among other things, the consolidation of manufacturing facilities and
processes, the scaling down of capacities at the remaining facilities to meet
anticipated market requirements and current economic conditions, suspension of
non-strategic business units, and the realignment of the organization to focus
on our two primary business segments: SCR Systems and Separation & Filtration.

     We believe that the result of these initiatives, including the redirection
of our resources to suspend the boiler business and focus on our two remaining
more profitable segments, will position us to maximize our current operational
efficiencies and allow us the flexibility to meet our customers' current and
anticipated needs, without sacrificing our ability to expand our business to
meet future demand. While the initial phase of our restructuring and
organizational realignment initiatives have been completed, we continue to look
for ways to improve our operational efficiencies and performance during these
trying times.


CRITICAL ACCOUNTING POLICIES

     The preparation of our financial statements in conformity with accounting
principles generally accepted in the United States of America requires us to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the date
of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Our estimates, judgments and assumptions are
continually evaluated based on available information and experience. Because of
the use of estimates inherent in the financial reporting process, actual results
could differ from those estimates.

     Certain of our accounting policies require a higher degree of judgment than
others in their application. These include revenue recognition on long-term
contracts, accrual for estimated warranty costs and allowance for doubtful
accounts. Our policies and related procedures for revenue recognition on
long-term contracts, accrual of warranty costs and allowance for doubtful
accounts are summarized below.

                                       14

                      FOR THE PERIOD ENDED MARCH 31, 2003

     Revenue Recognition. We provide products under long-term, generally
fixed-priced, contracts that may extend up to 18 months, or longer, in duration.
In connection with these contracts, we follow the guidance contained in AICPA
Statement of Position ("SOP") 81-1, "Accounting for Performance of
Construction-Type and Certain Production-Type Contracts." SOP 81-1 requires the
use of percentage-of-completion accounting for long-term contracts that contain
enforceable rights regarding services to be provided and received by the
contracting parties, consideration to be exchanged, and the manner and terms of
settlement, assuming reasonably dependable estimates of revenues and expenses
can be made. The percentage-of-completion methodology generally results in the
recognition of reasonably consistent profit margins over the life of a contract.
Amounts recognized in revenue are calculated using the percentage of
construction cost completed, generally on a cumulative cost to total cost basis.
Cumulative revenues recognized may be less or greater than cumulative costs and
profits billed at any point in time during a contract's term. The resulting
difference is recognized as "costs and earnings in excess of billings on
uncompleted contracts" or "billings in excess of costs and earnings on
uncompleted contracts."

     When using the percentage-of-completion method, we must be able to
accurately estimate the total costs we expect to incur on a project in order to
record the proper amount of revenues for that period. We continually update our
estimates of costs and status of each project with our subcontractors and our
manufacturing plants. If it is determined that a loss will result from the
performance of a contract, the entire amount of the loss is charged against
income when it is determined. The impact of revisions in contract estimates are
recognized on a cumulative basis in the period in which the revisions are made.
In addition, significant portions of the our costs are subcontracted under
fixed-price arrangements, thereby reducing the risk of significant cost overruns
on any given project. However, a number of internal and external factors,
including labor rates, plant utilization factors, future material prices,
customer change specifications, and other factors can affect our cost estimates.
While we attempt to reduce the inherent risk relating to revenue and cost
estimates in percentage-of-completion models through corporate policy, approval
and monitoring processes, any estimation process, including that used in
preparing contract accounting models, involves inherent risk.

     Product Warranties. We offer warranty periods of various lengths to our
customers depending upon the specific product and terms of the customer
agreement. We typically negotiate varying terms regarding warranty coverage and
length of warranty dependent upon the product involved and customary practices.
Our typical warranties require us to repair or replace defective products during
the warranty period at no cost to the customer. We attempt to obtain back-up
concurrent warranties for major component parts from our suppliers. As of the
balance sheet date, we record an estimate for warranty related costs for
products sold based on historical experience, expectation of future conditions
and the extent of back-up concurrent supplier warranties in place. While we
believe that our estimated warranty reserve is adequate and the judgment applied
is appropriate, the estimated liability for product warranties could differ from
future actual warranty costs due to a number of factors.

     Allowance for Doubtful Accounts. We maintain an allowance for doubtful
accounts to reflect estimated losses resulting from the inability of customers
to make required payments. On an ongoing basis, we evaluate the collectibility
of accounts receivable based upon historical collection trends, current economic
factors, and the assessment of the collectibility of specific accounts. We
evaluate the collectibility of specific accounts using a combination of factors,

including the age of the outstanding balances, evaluation of customers' current
and past financial condition and credit scores, recent payment history, current
economic environment, and discussions with our project managers and with the
customers directly. See Item 2 - "Management's Discussion and Analysis of

THREE MONTHS ENDED MARCH 31, 2003 COMPARED TO THREE MONTHS ENDED MARCH 31, 2002

     Revenue for the third quarter of fiscal 2003 was $13.6 million, a decrease
of $15.5 million, or 53.3%, over the third quarter revenues of $29.1 million for
fiscal 2002. For the quarter, revenue related to our SCR Systems segment
decreased $11.2 million, or 64.4%, from $17.4 million for the third quarter of
fiscal year 2002 to $6.2 million for the same quarter of fiscal 2003. Our
Separation & Filtration segment revenue declined approximately $500,000, or
6.9%, from $7.2 million for the third quarter of fiscal year 2002 to $6.7
million for the same quarter of fiscal 2003. Our Boiler segment revenues
decreased $3.8 million, or 84.4%, from $4.5 million to approximately $700,000
over the same periods. We feel that the decline in the construction of new power
plants, recent environmental regulatory uncertainties, and the current economic
climate have all contributed to the decline in sales in our SCR Systems and
Separation & Filtration segments. The decrease in Boiler segment revenues has
resulted primarily from our decision to suspend this operation during our
current fiscal year. See Item 2 - "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Restructuring and Organizational
Realignment" of this Report.

     Our backlog of unfilled orders was approximately $46 million at March 31,
2003, compared to $63 million at March 31, 2002, $45 million at December 31,
2002 and $38 million at September 30, 2002. We believe that the decrease in our
backlog compared with the prior year is

                       PEERLESS MFG. CO. AND SUBSIDIARIES
                                   FORM 1O-Q
                      FOR THE PERIOD ENDED MARCH 31, 2003

primarily due to the reduction in the construction of new power plants, recent
environmental regulatory uncertainties, and the current economic climate. All of
these factors have contributed to planned projects being placed on hold or
production rescheduled, and new environmental and gas treatment projects being
canceled or delayed. These factors resulted in the reduction in SCR Systems
orders booked during the second half of fiscal 2002, which is impacting our
reported revenues during this fiscal year. Regulations related to NOx emissions
have in the past resulted in increased sales of our SCR Systems, either through
new-source or retro-fit applications, and we anticipate that this trend will
continue in the future. However, current regulatory uncertainties have made the
ability to forecast these anticipated revenue streams extremely difficult. In
addition, while the construction of new power plants has seen a significant
decline over the past 12 months, there is expected to be a continued demand for
SCR Systems as new power plants are built to replace older, less efficient
plants, and as regulatory compliance projects are commenced, which has
attributed to some degree to the improvement in our backlog since September 30,
2002.

     Our gross profit decreased $4.6 million, or 57.5%, from $8.0 million to
$3.4 million for the three months ended March 31, 2002 and 2003, respectively.
Gross profit, as a percentage of sales, decreased to 24.9% for the three months
ended March 31, 2003, compared to 27.5% for the same period last year. Our
reported margins during the period were impacted, and in the future can be
expected to be impacted to some degree, by increased competitive market
pressures on our SCR Systems and by the general lower volume of sales which
impacts our manufacturing plant utilization. Because we manufacture a
significant portion of our products, fluctuations in revenues, from quarter to
quarter or period to period, will impact our manufacturing absorption
utilization factors which directly impacts our reported margins. In addition to
the foregoing, because certain products historically have higher margins than
others, our margins are impacted by shifts in the composition of our sales. This
was a factor in the current quarter where our SCR Systems revenues represented
only 45.5% of our total revenues, versus 59.7% of our total revenues for the
same quarter in fiscal 2002. Because we generally realize a higher margin on our
environmental products, a shift, as experienced this quarter, will have a
negative impact on our reported margins.

     Operating expenses decreased by $2.2 million, or 35.5%, from $6.2 million
for the three months ended March 31, 2002 to $4.0 million for the three months
ended March 31, 2003. The decrease in our operating expenses during the period
was due to the implementation of the our restructuring and organizational
realignment initiatives that began during the first quarter of fiscal 2003 (See
Item 2 - "Management's Discussion and Analysis of Financial Condition and
Results of Operations - Restructuring and Organizational Realignment" of this
Report). However, as operating expenses tend to be generally fixed in nature,
their relationship to revenues will be significantly impacted by fluctuations in
revenues due to seasonality factors, delays in production, etc. As a result, our
operating expenses, as a percentage of revenues, increased from 21.3% for the
three months ended March 31, 2002 to 29.7% for the three months ended March 31,
2003. While our operating expense, as a percentage of revenues, increased this
quarter, we feel our current operating structure is appropriate given our
current backlog. However, we will continue to monitor our operational levels in
relation to changes in our backlog and changes in the marketplace.

     Interest expense remained unchanged for the three months ended March 31,
2003 and March 31, 2002, because we had no outstanding debt during either of
these reporting periods.

                      FOR THE PERIOD ENDED MARCH 31, 2003

     Other income (expense) remained relatively constant, reflecting income of
$66,000 for the three months ended March 31, 2003 compared to $74,000 for the
three months ended March 31, 2002. The decline in other income (expense) related
primarily to a decrease in interest income earned during this period compared to
the same period last year, which directly correlates to lower effective yields
being earned by us on our investments. Our invested cash over the current period
was approximately $5.7 million compared to approximately $4.8 million for the
same period last year.

     As a result of the factors discussed above, we recorded a net loss for the
three months ended March 31, 2003 of approximately $375,000, or $0.13 per
diluted share compared to net earnings of approximately $1.2 million, or $0.38
per diluted share, for the three months ended March 31, 2002.


NINE MONTHS ENDED MARCH 31, 2003 COMPARED TO NINE MONTHS ENDED MARCH 31, 2002

     Revenue for the nine months ended March 31, 2003 was $48.8 million, a
decrease of $31.8 million, or 39.5%, over the corresponding period last year.
For the period, revenue related to our SCR Systems segment decreased $23.0
million, or 47.3%. Our Separation & Filtration segment revenue remained
relatively stable decreasing approximately $600,000, from $21.1 million for the
nine months ended March 31, 2002 to $20.5 million for the nine months ended
March 31, 2003. Our Boilers segment revenues decreased $8.2 million, or 75.2%,
from $10.9 million for the nine months ended March 31, 2002 to $2.7 million for
the nine months ended March 31, 2003. We believe that the decline in the
construction of new power plants, recent environmental regulatory uncertainties,
and the current economic climate have all contributed to the decline in revenues
in our SCR Systems segment and to some extent to the lack of growth in our
Separation & Filtration segment. The drop in Boiler segment revenues has
resulted primarily from our decision to suspend this operation during fiscal
2003. See Item 2 - "Management's Discussion and Analysis of Financial Condition
and Results of Operations - Restructuring and Organizational Realignment" of
this Report.

     Our gross profit decreased $10.9 million, or 49.8%, from $21.9 million for
the nine months ended March 31, 2003 to $11.0 million for the nine months ended
March 31, 2003. As a percentage of revenues our gross profit margin decreased
from 27.1% for the nine months ended March 31, 2002 to 22.5% for the nine months
ended March 31, 2003. Our margin decline during this period was partially due to
shifts in our product mix, competitive market pressures, and lower revenues, as
discussed previously in our discussion of our gross profit margins for the three
months ended March 31, 2003 and 2002. In addition to these factors, our margins
for the nine months March 31, 2003 were directly impacted by certain
unanticipated costs associated with the start-up and commissioning of several
SCR Systems projects during our second quarter of fiscal 2003 (reference is made
to our Form 10-Q for the period ended December 31, 2002 for further discussion
on this topic). Excluding these additional project costs, our reported margin,
as a percentage of revenues, for the nine months ended March 31, 2003, would
have been 24.5%.

     Operating expenses decreased by $3.7 million, or 21.0%, from $17.6 million
for the nine months ended March 31, 2002 to $13.9 million for the nine months
ended March 31, 2003. The decrease in operating expenses during the period was
due primarily to the implementation of our restructuring and organizational
realignment initiatives that began during the first three months of our current
fiscal year. In connection with these initiatives we have incurred, to date,
approximately $483,000 in severance and related benefits expenses. In addition,
during the

                                       18

second quarter of this fiscal year, we added an additional $400,000 to our
provision for doubtful accounts which we felt was necessary given the current
economic environment and uncertainties surrounding certain receivables. However,
as previously discussed, operating expenses tend to be generally fixed in
nature, and as such their relationship to revenues can be significantly impacted
by declines in revenues. As a result, operating expenses increased, as a
percentage of revenues, from 21.7% for the nine months ended March 31, 2002 to
28.4% for the nine months ended March 31, 2003. (26.6% excluding restructuring
charges and the additional provision for doubtful accounts). While our operating
expenses, as a percentage of revenues, have increased this year, we feel our
current operating structure is appropriate given our current backlog. However,
we will continue to monitor our operational levels in relation to changes in our
backlog and changes in the marketplace.

     Other income (expense), decreased by approximately $200,000 from income of
$291,000 for the nine months ended March 31, 2002 to $91,000 for the nine months
ended March 31, 2003. The decrease related primarily to a gain on the sale of
our Carrollton, Texas facility of approximately $267,000, which was included in
the operational results for the quarter ended December 31, 2001, offset by
additional interest and rental income in this year.

     As a result of the factors discussed above, we recorded a net loss for the
nine months ended March 31, 2003, of approximately $1.7 million, or $0.58 per
diluted share compared to net earnings of approximately $2.9 million, or $0.94
per diluted share, for the nine months ended March 31, 2002. Excluding the
impact of the additional project costs and provision for allowance for doubtful
accounts, during the second quarter of this fiscal year, we would have incurred
a net loss for the nine months ended March 31, 2003 of approximately $900,000,
or $.30 per diluted share.


LIQUIDITY AND CAPITAL RESOURCES

     Our cash and cash equivalents were approximately $6.5 million and $1.4
million as of March 31, 2003 and June 30, 2002, respectively. Cash provided by
operating activities was approximately $5.1 million for the nine months ended
March 31, 2003, compared to approximately $5.7 million for the same period last
year.

     Because we are engaged in the business of manufacturing custom systems, our
progress billing practices are event-oriented rather than date-oriented, and
vary from contract to contract. We customarily bill our customers after the
occurrence of certain project milestones. Billings to customers affect the
balance of billings in excess of costs and earnings or the balance of cost and
earnings in excess of billings, as well as the balance of accounts receivable.
Consequently, we focus on the net amount of these accounts, along with accounts
payable, to manage working capital. At March 31, 2003, the balance of these
working capital accounts was $8.3 million compared to $17.9 million at June 30,
2002, reflecting a reduction of our investment in these working capital items of
$9.6 million. This reduction in the working capital accounts was offset by our
net loss of approximately $1.7 million, an increase in other current assets of
approximately $.9 million, and a decrease in accrued liabilities, commissions,
and other payables of approximately $2.9 million.

     Cash used in investing activities was approximately $79,000 for the nine
months ended March 31, 2003, compared to approximately $893,000 for the same
period last year. The

                      FOR THE PERIOD ENDED MARCH 31, 2003

decrease in cash used during the current fiscal year related to a decrease in
capital expenditures during this period in connection with our cost containment
initiatives.

     We had approximately $64,000 of cash provided by financing activities
during the current period compared to approximately $1.4 million in cash used in
our financing activities during the period ended March 31, 2002. The prior year
usage related to the payoff of our installment debt on our Abilene, Texas
facility of approximately $1.6 million, offset by the proceeds from the issuance
of common stock, pursuant to employee stock options, of approximately $189,000.
The cash provided by financing activities, during the current period, related to
the cash received related to the issuance of common stock pursuant to our
employee stock options.

     We maintain a $10 million revolving line of credit facility that expires in
October 2003. The credit line carries a floating interest rate based on the
prime or Euros rate plus or minus an applicable margin (prime less .25%, Euros
plus 2.65%), and is secured by substantially all of our assets. The margin
factor is subject to a reduction schedule based on our attainment of certain
financial performance criteria. As of March 31, 2003, we had no outstanding
balances under the credit line, and $3.6 million outstanding under letters of
credit, leaving us with $6.4 million of availability under the facility. The
facility contains financial covenants, restrictions on capital expenditures,
acquisitions, asset dispositions, and additional debt, as well as other
customary covenants.

     The financial covenants, among other things, require that we not incur
losses in three consecutive quarters and that any losses (before taxes and
extraordinary items) incurred over this period not exceed $750,000. The quarter
ending March 31, 2003 represents the third consecutive quarterly loss, and for
the nine months then ended we incurred losses (before taxes and extraordinary
items) of approximately $2.8 million. As such, as of March 31, 2003, we are in
default of our loan agreement. We have obtained a temporary waiver from the bank
with respect to our default and anticipate we will be in compliance with the
aforementioned covenant upon completion of our fourth quarter. However, no
assurances can be given that we will in fact be in compliance with this covenant
upon the completion of our fourth quarter, or that the bank will be willing to
grant further waivers if we are not in compliance with this covenant upon
completion of our fourth quarter or in the event of further defaults. While we
believe that we maintain adequate liquidity to support our existing operations
and our planned growth, as well as to continue operations during reasonable
periods of unanticipated adversity, our inability to issue letters of credit
could negatively impact our ability to enter into certain contracts requiring
such instruments. While we feel that we would be able to substitute some other
form of guarantee, such as a performance/warranty/surety bonds, no assurances
can be given that we would be successful in this endeavor, or that such
instruments would be acceptable to our customers.

     Included in our financial statements is a $2.2 million receivable due from
a customer that recently filed a plan of reorganization under Chapter 11 of the
United States Bankruptcy Code (original amount of the contract was approximately
$6.1 million). We have been classified as an unsecured creditor under such
filing. We have obtained outside counsel to help with the collection of this
receivable and have filed a statutory lien on the refinery where our equipment
was installed. In addition, we have filed a lawsuit to perfect our lien interest
against the owner of the refinery. While we have reason to believe that our lien
will be found to be valid, no assurances can be given. We intend to vigorously
pursue the collection of this receivable and believe that it will be collected.
In the event that our lien is held to be invalid, or if the

receivable or a significant portion thereof is deemed to be not collectible, we
will be required to write down the receivable to its net realizable value. To
the extent that our existing allowance for doubtful accounts is not adequate to
cover this write down, the additional reserve required will be a charge against
our operating results. Such an event could have a material adverse impact on our
financial condition and reported results of its operations, and in addition,
could potentially trigger a violation of our loan covenants. While we would
attempt, and have reason to believe that we would be able, to obtain a waiver
for such violations, or find other lending alternatives, no assurances can be
given that we would be successful in such endeavors.


NEW ACCOUNTING STANDARDS

     In July 2002, the Financial Accounting Standards Board ("FASB") issued
Statement No. 146, "Accounting for Costs Associated with Exit or Disposal
Activities." The Statement requires companies to recognize costs associated with
exit or disposal activities when they are incurred rather than at the date of a
commitment to an exit or disposal plan. FASB Statement No. 146 is to be applied
prospectively to exit or disposal activities initiated after December 31, 2002.
We do not expect the adoption of this pronouncement to have a material impact on
our financial condition or results of operations.

     In November 2002, FASB reached a consensus on EITF Issue 00-21, "Accounting
for Revenue Arrangements with Multiple Deliverables". The guidance in this Issue
is effective for revenue arrangement entered into in fiscal years beginning
after June 15, 2003. The Issue addresses certain aspects of the accounting by a
vendor for arrangements under which it will perform multiple revenue-generating
activities and whether, as a result, there is embedded more than one earnings
process for revenue recognition purposes. We do not expect the adoption of this
pronouncement to have a material impact on our financial condition or results of
operations.

     In November 2002, FASB issued FASB Interpretation ("FIN") No. 45,
"Guarantor's Accounting and Disclosure Requirements for Guarantees of
Indebtedness of Others." This Interpretation clarifies the requirements of SFAS
No. 5, "Accounting for Contingencies," relating to the guarantor's accounting
for, and disclosure of, the issuance of certain types of guarantees. The
Interpretation's provision for initial recognition and measurement are required
on a perspective basis to guarantees issued or modified after December 31, 2002.
The disclosure requirements are required for financial statements of interim or
annual reports that end after December 15, 2002. We have adopted FIN No. 45 and
have included the new disclosure requirements in Note 4 - "Product Warranties"
to the Notes to the Consolidated Financial Statements.

     In January 2003, FASB issued FIN No. 46, "Consolidation of Variable
Interest Entities." This Interpretation of Accounting Research Bulletin No. 51,
"Consolidated Financial Statements," addresses consolidation by business
enterprises of variable interest entities which possess certain characteristics.
The Interpretation requires that if a business enterprise has a controlling
financial interest in a variable interest entity, the assets, liabilities, and
results of the activities of the variable interest entity must be included in
the consolidated financial statements with those of the business enterprise.
This interpretation applies immediately to variable interest entities created
after January 31, 2003 and to variable interest entities in which an enterprise
obtains an interest after that date. We did not have any ownership interest in
any variable interest entities as of March 31, 2003.

                      FOR THE PERIOD ENDED MARCH 31, 2003

     In April 2003, FASB issued Statement No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities." FASB Statement No. 149
requires that contracts with comparable characteristics be accounted for
similarly. The Statement clarifies the circumstances in which a contract with an
initial net investment meets the characteristics of a derivative, and when a
derivative contains a financing component and amends certain other existing
pronouncements. This Statement is effective for contracts entered into or
modified after June 30, 2003. We do not expect the adoption of this
pronouncement to have a material impact on our financial condition or results of
operations.


FACTORS THAT MAY AFFECT OUR OPERATING RESULTS AND OTHER RISK FACTORS

     Investing in our common stock involves a high degree of risk. Any of the
following risks could have a material adverse effect on our financial condition,
liquidity, results of operations or prospects, financial or otherwise. Reference
to these factors in the context of a forward-looking statement or statements
shall be deemed to be a statement that any one or more of the following factors
may cause actual results to differ materially from those in such forward-looking
statement or statements. See Item 2 - "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Forward-Looking Statements" of
this Report.


     CHANGES IN THE POWER GENERATION INDUSTRY AND/OR THE ECONOMY COULD HAVE AN
ADVERSE IMPACT ON OUR SALES OF SCR SYSTEMS AND OUR OPERATING RESULTS.

     The demand for our SCR Systems depends to an extent on the continued
construction of power generation plants and upgrade of existing power plants. In
the current year, approximately 52.5% of our consolidated revenues were derived
from sales of SCR Systems for new and refurbished power plants versus
approximately 60.3% for the same period last year. The power generation industry
has experienced cyclical periods of slow growth or decline. Any change in the
power plant industry that results in a decline in the construction of power
plants or a decline in the upgrading of existing power plants could have a
materially adverse impact on our SCR Systems segment revenues and our results of
operations. See Item 2 - "Management's Discussion and Analysis of Financial
Condition and Results of Operations" of this Report.


     CHANGES IN CURRENT ENVIRONMENTAL LEGISLATION COULD HAVE AN ADVERSE IMPACT
ON THE SALE OF OUR SCR SYSTEMS AND ON OUR OPERATING RESULTS.

     Laws and regulations governing the discharge of pollutants into the
environment or otherwise relating to the protection of the environment or human
health have played a part in the increased use of SCR Systems in the United
States. These laws include U.S. federal statutes such as the Resource
Conservation and Recovery Act of 1976, the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, or CERCLA, the Clean Water Act and the
Clean Air Act, and the regulations implementing them, as well as similar laws
and regulations at state and local levels and in other countries. These laws and
regulations may change or other jurisdictions may not adopt similar laws and
regulations. Our SCR Systems business is primarily regulatory driven. This
business will be adversely impacted to the extent that current regulations
requiring the reduction of NOx emissions are repealed, amended or implementation
dates delayed

or to the extent that regulatory authorities minimize enforcement.
See Item 2 - "Management's Discussion and Analysis of Financial Condition and
Results of Operations" of this Report.


     COMPETITION COULD RESULT IN LOWER SALES AND DECREASED MARGINS.

     We operate in highly competitive markets worldwide. Competition could
result in not only a reduction in our sales, but also a reduction in the prices
that we can charge for our products. To remain competitive we must be able to
not only anticipate or respond quickly to our customers' needs and enhance and
upgrade our existing products and services to meet those needs, but also
continue to price our products competitively. Our competitors may develop
cheaper, more efficient products or may be willing to charge lower prices for
strategic marketing or to increase market share. Some of our competitors have
more capital and resources than we do and may be better able to take advantage
of acquisition opportunities or adapt more quickly to changes in customer
requirements. See Item 2 - "Management's Discussion and Analysis of Financial
Condition and Results of Operations" of this Report.


     WE ENTER INTO FIXED-PRICED CONTRACTS. IF OUR ACTUAL COSTS EXCEED OUR
ORIGINAL ESTIMATES, OUR PROFITS WILL BE REDUCED.

     The majority of our contracts are on a fixed-price basis. Although we
benefit from cost savings, we have limited ability to recover cost overruns.
Because of the large scale and long duration of our contracts, unanticipated
cost increases may occur as a result of several factors, including, but not
limited to, (1) increases in the cost, or shortages of components, materials or
labor; (2) unanticipated technical problems; (3) required project modifications
not initiated by the customer; and (4) suppliers' or subcontractors' failure to
perform. These factors may also delay delivery of our products and our contracts
often provide for liquidated damages for late delivery. Unanticipated costs that
we cannot pass on to our customers or the payment of liquidated damages under
fixed contracts will negatively impact our profits. See Item 2 - "Management's
Discussion and Analysis of Financial Condition and Results of Operations" of
this Report.


     OUR BACKLOG MAY NOT BE INDICATIVE OF OUR FUTURE REVENUE.

     Customers may cancel or delay projects for reasons beyond our control. Our
orders normally contain cancellation provisions, which permit us to recover only
our costs and a portion of our anticipated profit in the event a customer
cancels its order. If a customer elects to cancel, we may not realize the full
amount of revenues included in our backlog. If projects are delayed, the timing
of our revenues could be affected and projects may remain in our backlog for
extended periods of time. Revenue recognition occurs over long periods of time
and is subject to unanticipated delays. If we receive relatively large orders in
any given quarter, fluctuations in the levels of our quarterly backlog can
result because the backlog in that quarter may reach levels that may not be
sustained in subsequent quarters. Our backlog may not be indicative of our
future revenues.


     OUR ABILITY TO CONDUCT BUSINESS OUTSIDE THE UNITED STATES MAY BE ADVERSELY
AFFECTED BY FACTORS OUTSIDE OF OUR CONTROL AND OUR REVENUES AND PROFITS FROM
INTERNATIONAL SALES COULD BE ADVERSELY IMPACTED.

     In fiscal 2002, approximately 14.5% of our revenue was derived from sales
outside the United States. For fiscal 2003, revenue outside the United States
represented approximately

                      FOR THE PERIOD ENDED MARCH 31, 2003

19.5% of our consolidated revenues. Our operations and earnings throughout the
world have been, and may in the future be, affected from time to time in varying
degrees by war, political developments and foreign laws and regulations, such as
regional economic uncertainty, political instability, restrictions, customs and
tariffs, changing regulatory environments, fluctuations in foreign currency
exchange rates and adverse tax consequences. The likelihood of such occurrences
and their overall effect upon us vary greatly from country to country and are
not predictable. These factors may result in a decline in revenues or
profitability and could adversely affect our ability to expand our business
outside of the United States.


     OUR FINANCIAL PERFORMANCE MAY VARY SIGNIFICANTLY FROM QUARTER TO QUARTER,
MAKING IT DIFFICULT FOR US TO ESTIMATE FUTURE REVENUE.

     Our quarterly revenues and earnings have varied in the past and are likely
to vary in the future. Our SCR Systems contracts generally stipulate customer
specific delivery terms and may have contract cycles of a year or more, which
subjects them to many factors beyond our control. In addition, these contracts
are significantly larger in size than our typical Separation & Filtration
contracts, which tends to intensify their impact on our quarterly operating
results. Furthermore, as a significant portion of our operating costs are fixed,
an unanticipated decrease in our SCR Systems revenues, a delay or cancellation
of orders in backlog, or a decrease in the demand for our SCR Systems products,
may have a significant impact on our quarterly operating results. Therefore, our
quarterly operating results may be subject to significant variations and our
operating performance in one quarter may not be indicative of our future
performance. See Item 2 - "Management's Discussion and analysis of Financial
Condition and Results of Operation" of this report.


     OUR PRODUCTS ARE COVERED BY WARRANTIES. UNANTICIPATED WARRANTY COSTS OR
PRODUCT LIABILITY CLAIMS NOT COVERED BY INSURANCE COULD ADVERSELY AFFECT OUR
FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

     We provide warranties on our products generally for terms of three years or
less. These warranties require us to repair or replace faulty products and meet
certain performance standards, among other customary warranty provisions. While
we continually monitor our warranty claims and provide a reserve for our
estimate of potential warranty issues on an on-going basis, an unanticipated
claim could have a material adverse impact on our operations. In some cases, we
may be able to subrogate a claim back to a subcontractor, if the subcontractor
supplied the defective product or performed the service, but this may not always
be possible. The need to repair or replace products with design or manufacturing
defects could temporarily delay the sale of new products and could adversely
affect our reputation.

     In addition, we may be subject to product liability claims involving claims
of personal injury or property damage. While we maintain product liability
insurance coverage to protect us in the event of such a claim, such coverage may
not be adequate to cover the cost of our defense and the potential award in the
event of a claim. Also, a well-publicized actual or perceived problem could
adversely affect our reputation and reduce the demand for our products.

     LARGE CONTRACTS REPRESENT A SIGNIFICANT PORTION OF OUR ACCOUNTS RECEIVABLE,
WHICH INCREASES OUR EXPOSURE TO CREDIT RISK.

     We continue to closely monitor the credit worthiness of our customers and
have not, to date, experienced any significant credit losses. Significant
portions of our sales are to customers who place large orders for custom
products and whose activities are related to the power industry. As such, our
exposure to credit risk is affected to some degree by conditions within the
power industry and governmental and/or political conditions. We try to mitigate
our exposure to credit risk, to some extent, by requiring progress payments and
letters of credit. However, as some of our exposure is outside of our control,
unanticipated events could have a materially adverse impact on our operating
results. See Item 2 - "Management's Discussion and Analysis of Financial
Condition and Results of Operation - Liquidity and Capital Resources" of this
Report.


     THE TERMS AND CONDITIONS OF OUR CREDIT FACILITY IMPOSE RESTRICTIONS ON OUR
OPERATIONS. WE MAY NOT BE ABLE TO RAISE ADDITIONAL CAPITAL, IF NEEDED.

     The terms and conditions of our current $10 million revolving credit
facility impose restrictions that affect, among other things, our ability to
incur debt, make capital expenditures, merge, sell assets, make distributions,
or create or incur liens. Availability of our credit facility is also subject to
certain financial covenants, amongst others, a prohibition against losses in any
three consecutive quarters or aggregate losses (before taxes and extraordinary
items) in any three consecutive quarters exceeding $750,000. Our ability to
comply with the covenants may be affected by events beyond our control and we
cannot assure you that we will achieve operating results that meet the
requirements of the credit agreement. A breach of any of these covenants could
result in a default under our credit facility. In the event of a default, the
bank could elect to declare the outstanding principal amount of our credit
facility, all interest thereon, and all other amounts payable under our credit
facility to be immediately due and payable. As of March 31, 2003 we are in
default of our credit agreement. See Item 2 - "Management's Discussion and
Analysis of Financial Condition and Results of Operation - Liquidity and Capital
Resources" of this Report.

     Our ability to satisfy any debt obligations will depend upon our future
operating performance, which will be affected by prevailing economic, financial
and business conditions and other factors, some of which are beyond our control.
We anticipate that borrowings from our existing revolving credit facility, or
the refinancing of our revolving credit facility, and cash provided by operating
activities, would provide sufficient funds to finance capital expenditures,
working capital and otherwise meet our operating expenses and service our debt
requirements as they become due. However, in the event that we require
additional capital, there can be no assurance that we will be able to raise such
capital when needed or on satisfactory terms, if at all. See Item 2 -
"Management's Discussion and Analysis of Financial Condition and Results of
Operation - Liquidity and Capital Resources" of this Report.


     OUR BUSINESS IS SUBJECT TO RISKS OF TERRORIST ACTS AND ACTS OF WAR.

     Terrorist acts and acts of war may disrupt our operations, as well as our
customers operations. Such acts have created, and continue to create, economic
and political uncertainties and have contributed to the global economic downturn
that we are currently facing. Any future terrorist activities, or any continued
military or security operations could further weaken the global economy and
create additional uncertainties forcing our customers to further reduce their

capital spending, or cancel or delay already planned construction projects,
which could have a material adverse impact on our business, operating results
and financial condition.


     OUR COMMON STOCK IS THINLY TRADED, WHICH MAY RESULT IN LOW LIQUIDITY.

     The daily trading volume of our common stock is relatively low and
therefore the liquidity and appreciation in our stock may not meet our
shareholders' expectations. The market price of our common stock could be
adversely impacted as a result of sales by our existing shareholders of a large
number of shares of our common stock in the market, or the perception that such
sales could occur.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Our primary market risk exposures are in the areas of interest rate risk
and foreign currency exchange rate risk. We feel our risk to interest rate
fluctuations is nominal, as our investments are short-term in nature and we are
currently not, nor do we expected to be, in a borrowing position. Our exposure
to currency exchange rate fluctuations has been, and is expected to continue to
be, modest due to the fact that the operations of our UK subsidiary are almost
exclusively conducted in their local currency. The impact of currency exchange
rate movements on inter-company transactions has been, and is expected to
continue to be, immaterial. We, on occasion, will purchase derivative
transactions with respect to contracts entered into by our domestic operations
which have been sold in currencies other than US dollars, but the impact of any
fluctuation in the exchange rates in these hedged currencies, would be expected
to have an immaterial impact on our financial operations.


ITEM 4. CONTROLS AND PROCEDURES

     We maintain disclosure controls and procedures that are designed to ensure
that information required to be disclosed in our reports and filings under the
Exchange Act is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms. The disclosure controls and
procedures also are designed to ensure that such information is accumulated and
communicated to our management, including our Chief Executive Officer and Chief
Financial Officer, as appropriate, to allow timely decisions regarding
disclosure based closely on the definition of "disclosure controls and
procedure" in Rule 13a-14(c) of the Exchange Act. In designing and evaluating
the disclosure controls and procedures, management recognizes that any controls
and procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives, and management
necessarily is required to apply judgment in evaluating the cost-benefit
relationship of possible controls and procedures (as defined in Exchange Act
Rules 13a-14(c) and 15d-14(c)).

     Within 90 days prior to the date of this Report on Form 10-Q, we carried
out an evaluation, under the supervision and with the participation of the our
management, including our Chief Executive Officer and Chief Financial Officer,
of the effectiveness of the design and operation of our disclosure controls and
procedures (as defined in Exchange Act Rules 13a-14(c) and 15d-14(c)). Based on
the foregoing, our Chief Executive Officer and Chief Financial Officer concluded
that our disclosure controls and procedures were effective.

                      FOR THE PERIOD ENDED MARCH 31, 2003

     There have been no significant changes in our internal controls or in other
factors that could significantly affect these controls subsequent to the date we
completed our evaluation and as of the date of the filing of this Report on Form
10-Q.


PART II. OTHER INFORMATION

ITEMS 1, 2, 4 AND 5 ARE NOT APPLICABLE AND HAVE BEEN OMITTED

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

          We maintain a $10 million revolving line of credit facility that
     expires in October 2003. As of March 31, 2003, we had no outstanding
     balances under the credit line, and $3.6 million outstanding under letters
     of credit, leaving us with $6.4 million of availability under the facility.
     The facility contains financial covenants, restrictions on capital
     expenditures, acquisitions, asset dispositions, and additional debt, as
     well as other customary covenants. The financial covenants, among other
     things, require that we not incur losses in three consecutive quarters and
     that any losses (before taxes and extraordinary items) incurred over this
     period not exceed $750,000. The quarter ending March 31, 2003 represents
     the third consecutive quarterly loss for us and for the nine months then
     ended we incurred losses (before taxes and extraordinary) of approximately
     $2.8 million. As such we are in default of our loan agreement as of March
     31, 2003. We have obtained a temporary waiver from the bank with respect to
     this default and we anticipate being in compliance with the aforementioned
     covenant upon completion of our fourth quarter. However, no assurances can
     be given that we will in fact be in compliance with this covenant upon the
     completion of our fourth quarter, or that the bank will be willing to grant
     further waivers if we are not in compliance with the covenant upon the
     completion of our fourth quarter or in the event of further defaults.
