                NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                      For the Three Months Ended July 31, 1998

1.   In the opinion of the management of the Company, the accompanying unaudited
     condensed consolidated financial statements contain all adjustments
     (consisting only of normal recurring accruals) necessary to present fairly
     the financial position, statements of operations, cash flows and
     comprehensive operations for the interim periods presented.  These interim
     financial statements should be read in conjunction with the April 30, 1998
     consolidated financial statements.

2.   Basic earnings per share represents net income available to common
     stockholders divided by the weighted average number of shares outstanding
     during the period.  Diluted earnings per share represents net income
     available to common stockholders divided by the weighted average number of
     shares outstanding including the potentially dilutive impact of stock
     options, where appropriate. 

     Basic shares outstanding for the three months ended July 31, 1998 and 1997
     were 14,898,000 and 14,560,000, respectively.  Diluted shares outstanding
     for the three months ended July 31, 1998 and 1997 were 15,347,000 and
     14,560,000, respectively.

                   FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                          
RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JULY 31, 1998 AND 1997

     THE RESULTS OF OPERATIONS FOR THE FIRST QUARTER OF FISCAL 1999 FOR FLOW
INTERNATIONAL CORPORATION ("FLOW" OR THE "COMPANY") INCLUDE ONLY THE CORE
ULTRAHIGH-PRESSURE ("UHP") OPERATIONS, WHILE THE PRIOR YEAR QUARTER INCLUDES THE
ACCESS AND SERVICES OPERATIONS IN ADDITION TO THE UHP OPERATIONS.  The Access
and Services operations were sold during the second quarter of fiscal 1998. 
Associated with this sale, the Company recorded a $4.9 million restructuring
provision during the first quarter of fiscal 1998 to write down the assets sold
to net realizable value as well as provide for probable future obligations
associated with the sale.  This charge is included as a separate component of
operating expenses in the accompanying Consolidated Statements of Operations.

     Given this significant disposition of operations during fiscal year 1998,
two separate Results of Operations reviews have been provided.  The "UHP RESULTS
OF OPERATIONS ANALYSIS" provides a review of the UHP operations for the three
month period ended July 31, 1998 and 1997 and the "ACCESS AND SERVICES
OPERATIONS ANALYSIS" reviews the results of operations for Access and Services
for the three month period ended July 31, 1998 and 1997.  

     The following pro forma table separates the Company's Consolidated
Statement of Operations into the ongoing operations (UHP) and the divested
operations (Access and Services).  The Access and Services results include the
restructuring charge:

     Revenue for the three months ended July 31, 1998 was $36.4 million, an
increase of $5.8 million (19%) as compared to the prior year of $30.7 million. 
Geographically, revenue from North America and Europe increased 23% and 18%,
respectively, compared to the prior year.  Revenue from Asia decreased 3% as
compared to the prior year; however, excluding the effects of exchange rate
changes between periods, sales in Asia increased 12% over the prior year.  Asia
represented 10% of fiscal 1999 revenues as compared to 12% of revenues in the
first quarter of fiscal 1998.  The Company's revenue can be segregated into two
primary groups, systems and consumables.  In general, a system is comprised of a
pump along with the robotics or articulation to move the cutting or cleaning
head and may also include automation capabilities.  Consumables represent parts
used by the UHP systems during operation.  Systems and consumables revenues of
$23.3 million and $13.1 million increased 23% and 12% for the quarter,
respectively over the prior year periods.

     Gross profit expressed as a percentage of revenues (gross margin rate) 
was 43% as compared to 42% in the prior year quarter.  In general, UHP 
systems sales have gross margin rates less than 40% and consumable parts 
sales have margins in excess of 50%.  As such, the gross margin rate can vary 
depending on the revenue mix between the various types of systems and 
consumable sales.  The gross margin rate increased even

with a continued shift in revenue mix towards lower margin system business. 
This gross margin improvement reflects the benefit of lower costs on the 
standard system product line as a result of increased production and 
productivity enhancements.

     Operating expenses of $12.5 million increased $2.5 million (25%) for the
quarter ended July 31, 1998, compared to the prior year.  Marketing expenses
increased $859,000 (18%) to $5.7 million as compared to the prior year period. 
Expressed as a percentage of revenue however, marketing expenses remained
comparable at 16% versus the prior year.  Research and engineering expense
increased $822,000 (37%) to $3.1 million for the quarter.  As a percent of
revenue, research and engineering expenses were 8%, an increase from 7% in the
prior year.  This reflects the Company's continued aggressive pursuit of
technological advances through increased research and engineering spending.  The
effect of this increase from 7% to 8% of revenues, represents an additional
$400,000 in quarterly expenses, roughly $.02 per diluted share.  General &
administrative expense of $3.7 million increased $795,000 (27%) for the quarter
as compared to the prior year period.  However, general and administrative
expenses expressed as a percent of revenue were the same in both the current and
prior year quarter.  Total operating expenses expressed as a percent of revenue
were 34% for the current quarter, as compared to 33% in the prior year quarter.

     Operating income for the quarter ended July 31, 1998 was $3.3 million, an
increase of $546,000 (20%) over the prior year quarter.

     First quarter fiscal 1999 interest and other expense, net of $718,000
represents an increase of $40,000 (6%) versus the prior year.  Included in this
net amount is $763,000 of interest expense which was comparable to the prior
year.

     Based upon the expected tax position of the Company for fiscal 1999, taxes
have been provided for at 31% of pre-tax income.  First quarter fiscal 1998
taxes were provided for at 35% of pre-tax income; however, the net tax rate for
the twelve months in fiscal 1998 was 29%.  This decrease in tax rates within
fiscal 1998, reflects changes between first quarter fiscal 1998 projected, and
year end actual pre-tax income in various taxing jurisdictions.  The increased
rate of 31% in fiscal 1999 as compared to the net twelve month fiscal 1998 rate
of 29% is reflective of the projected change in mix of pre-tax income to higher
taxing jurisdictions.  The income tax rate was lower than the statutory rate in
both the current and prior year due primarily to lower foreign tax rates,
benefits from the foreign sales corporation, and an ongoing review of the
Company's FAS 109 valuation allowance.

     Basic shares outstanding for the three months ended July 31, 1998 and 1997
were 14,898,000 and 14,560,000, respectively.  Diluted shares outstanding for
the three months ended July 31, 1998 and 1997 were 15,347,000 and 14,895,000,
respectively.

     The Company recorded net income of $1.8 million, or $.12 per Basic and
Diluted share for the three months ended July 31, 1998, compared to $1.4
million, or $.09 per Basic and Diluted share for the same prior year period.


ACCESS AND SERVICES OPERATIONS ANALYSIS -

     The Access and Services operations were sold during fiscal 1998 and thus
did not have any activity during the first quarter of fiscal 1999.

LIQUIDITY AND CAPITAL RESOURCES

     The Company used $2.7 million in cash from operations during the three
months ended July 31, 1998 as compared to cash generated by operating activities
of $2.5 million in the prior year.  The use of cash is related to the growth in
inventory, as well as a reduction in trade and other liabilities.  Total debt at
July 31, 1998 was $41.6 million, up $2.7 million from April 30, 1998.  The
Company believes that the available credit facilities and working capital
generated by operations, will provide sufficient resources to meet its operating
and capital requirements.  The Company's Credit Agreement and Private Placement
require the Company to comply with certain financial covenants.  As of July 31,
1998, the Company was in compliance with all such covenants.

     Gross trade receivables at July 31, 1998 increased $1.1 million (3%), from
April 30, 1998.  This increase is a function of a shift in revenue mix towards
large system sales, as well as several large billings late in the quarter on
percentage of completion projects. Days sales in gross accounts receivable can
be negatively impacted by the traditionally  longer payment cycle outside the
United States as well as that longer payment terms are sometimes negotiated on
large system orders.  The Company's management does not believe these timing
issues will present a material adverse impact on the Company's short-term
liquidity requirements.

     Inventories at July 31, 1998 increased $2.8 million (8%) from April 30,
1998.  This increase is in both parts and finished goods.  The increase reflects
the continued increasing demand for the Company's products, as well as new
product inventory.  Certain products manufactured by Flow Robotics and Flow
Automation can require an extended manufacturing period and thus impact
inventory levels from period to period.

     The Company is currently converting its existing computer applications to
help ensure readiness for the potential impact of the year 2000 date. 
Additionally, the Company is interviewing key suppliers and customers to ensure
readiness on their part.  Management currently estimates the project will be
completed in early calendar 1999 and the associated costs will be less than
$150,000.
