DIASYS CORPORATION & SUBSIDIARY
NOTES TO FINANCIAL STATEMENTS
SEPTEMBER 30, 2002

Note 1. Basis of the Presentation:

The accompanying unaudited consolidated financial statements include the
accounts of DiaSys Corporation and DiaSys Europe Limited its wholly owned
subsidiary.  The consolidated balance sheet for the end of the preceding
fiscal year has been derived from the Company's last audited consolidated
balance sheet contained in the Company's Form 10-KSB and is provided for
comparative purposes.  All other consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-QSB and
Rule 10-01 of Regulation S-X.  Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements.  In the opinion of management, all
adjustments, which include only normal recurring adjustments necessary to
fairly present the consolidated financial position, results of operations and
changes in cash flows for all periods present, have been made.  Operating
results for the three-month period ended September 30, 2002 are not
necessarily indicative of the results that may be expected for the year ending
June 30, 2003.  For further information, refer to the consolidated financial
statements and footnotes included in the Company's annual report on Form 10-
KSB for the year ended June 30, 2002.


Note 2.  Stock Options

The Company accounts for stock option grants using the intrinsic value based
method prescribed by APB Opinion No. 25.  Since the exercise price equaled or
exceeded the estimated fair value of the underlying shares at the date of
grant, no compensation was recognized in the three months ended September 30,
2002.

Had compensation cost been based upon the fair value of the option on the date
of grant, as prescribed by SFAS No. 123, the Company's pro forma net loss and
net loss per share would have been approximately  $(938,432) and $(0.09) per
share at September 30, 2002, using the Black-Scholes option pricing model.

Note 3.  Legal Proceedings


In 1999, the Company and its now subsidiary entered into separate, concurrent
multiple-year sales agreements with a distributor based in Istanbul Turkey.
The distribution agreements were made with Lenta Teshis Orunleri Ticaret ve
Sanayi Ltd. St. and its affiliates and subsidiaries ("Lenta").  Under the
agreements, Lenta purchased a total of $383,781 worth of products over two
years for which it paid the Company and its subsidiary a total of $139,901.
On December 19, 2001, following numerous discussions, the Company and Lenta
executed an Agreement of Payment pursuant to which Lenta acknowledged its debt
of $262,042 and agreed to pay the monies owed in ten equal monthly
installments.  On January 17, 2002, the Company and Lenta (together with
Lenta's affiliates and subsidiaries) entered into a new distribution agreement
through which Lenta was authorized to sell and service the Company's products
in Turkey so long as Lenta, its affiliates and subsidiaries, continued to make
timely payments under the above Agreement, the terms of which were restated in
the distribution agreement.

In January 2002, Lenta made two wire transfers to the Company totaling
$22,000, which was $4,204 less than the first installment required under the
agreement.  Lenta made no additional wire transfers or payments thereafter
despite numerous telefaxed promises made by Ali Ipyurt, Lenta's General
Manager.  On April 9, 24, and 29, 2002 the Company informed Lenta by telefax
that if Lenta could not bring its installment obligations to date by May 1,
2002, the Company would have no choice but to terminate the distribution
agreement for breach of contract, name a new distributor in the territory and
proceed against Lenta for collection and costs.   On May 21, 2002 the Company,
having received no additional funds from Lenta, terminated the distribution
agreement and put Lenta on notice that the Company would commence legal
recourse in both the United States and Turkey under the terms of the
distribution agreement.  The Company has started the legal process against
Lenta and taken a reserve of 50% or $120,000 against the Lenta receivable.
The Company's management will review the sufficiency of the reserve on a
quarterly basis based on the progress of its collection activities.

On June 8, 2002, the Company appointed a new distributor in Turkey, Ekin
Medical, who has ordered and received $150,000 worth of the Company's
products.

Note 4. Subsequent Events

On October 1, 2002 the Company announced that had received $70,000 in initial
stocking orders from Merck Centroamericana SA under the terms of a two-year
sales and service agreement between the parties.  Merck will distribute DiaSys
products in Guatemala, Honduras and Nicaragua.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANICAL CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources:

As of September 30, 2002, the Company had cash and cash equivalents of $6,472
compared to $544,192 at June 30, 2002.  The decrease in cash and cash
equivalents was due to the timing in collection of several large international
receivables where net terms are typically 60-to-90 days, including a
receivable of approximately $250,000 from the Company's strategic business
partner in Guangzhou, China.  The Company also uses cash to fund its
operations.

Based on cash, collection of receivables, and improving sales, management
believes that it will have sufficient funds and resources on hand to discharge
its obligations as they become due for at least the next 12 months.





RESULTS OF OPERATIONS

Three Months Ended September 30, 2002 as Compared to the Three Months Ended
September 30, 2001.

Net Revenue:

The Company's net revenue increased $183,285 to $672,721, or 37.4%, for the
quarter ended September 30, 2002 compared to $489,436 for the same period of
the prior year.  The increase in net revenue was due to continued
implementation of the Company's strategic selling plan expanding business
throughout Europe, Pacific Asia and Latin America.

Gross Profit and Gross Profit Margins:

Gross profit increased $118,339 to $434,555, or 37.4%, for the period ended
September 30, 2002, up from $316,216 compared to the same period of the prior
year.  Gross profit percentage of 65% remained essentially unchanged.  The
increase in gross profit is the direct result of increased sales.  The
consistent gross profit margin was the result of controlled manufacturing
costs.  The Company expects its gross profits and gross profit margins to
increase as sales increase, especially through the Company's newly constituted
sales team and domestic sales network.

Selling General And Administrative (SG&A):

SG&A increased $99,610 or 18.6% to $635,280 for the period ended September 30,
2002, up from $535,670 for the same period last year.  The increase in SG&A
was mainly due to an increase in American and European sales personnel and
sales related travel, worldwide.

Research And Development (R&D):

R&D expenses remained essentially unchanged at $114,212 for the period ended
September 30, 2002, compared to $134,527 for the same period last year.

Net (Loss):

Net loss decreased $33,021 to $311,079, or 9.6%, during the period ended
September 30, 2002, down from $344,100 for the same period of the prior year.
The decrease in loss was attributable to increased sales and continued expense
control.  The Company expects its net loss to continue to decrease as it
implements its strategic growth plan.

ITEM 3. PROCEDURES AND CONTROLS

Within the 90 days prior to the date of this report, the Company carried out
an evaluation, under the supervision and with the participation of the
Company's management, including the Company's Chief Executive Officer and
Chief Financial Officer its principal executive officer and principal
financial officer, of the effectiveness of the design and operation of the
Company's disclosure controls and procedures pursuant to Exchange Act Rule
13a-14.  Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that the Company's disclosure controls and
procedures are effective in timely alerting them to material information
required to be included in our periodic Securities and Exchange Commission
filings.  There were no significant changes in the Company's internal controls
or in other factors that could significantly affect these controls subsequent
to the date of their evaluation.
