 DIASYS CORPORATION 

  

  Common Stock Purchase Warrant 

  

  1,250,000 Shares 

  

  Void after December 30, 2007

	1.	Holder's Right to Purchase.

 

                  DIASYS
CORPORATION, a Delaware corporation (the "Company"), hereby certifies that for
value received, JOHN WINFIELD or his assigns (the "Holder"), is entitled, subject
to the terms and conditions set forth in this Common Stock Purchase Warrant (the
"Warrant"), to purchase from the Company up to One Million Two Hundred Fifty Thousand
(1,250,000) fully paid and non-assessable shares of Common Stock, $.001 par value,
of the Company (the "Common Stock") at a purchase price of Fifty Cents ($ .50)
per share, at any time or from time to time after close of business on December
30, 2004 and before 5:00 p.m., Eastern Time, on December 30, 2007. This right
to purchase shares of Common Stock of the Company may be exercised in whole or
in part and is further subject to the terms and provisions set forth herein. 

 
	2.	Exercise of Warrant.

                  2.1
       Manner of Exercise. To exercise
this Warrant in whole or in part, the Holder shall deliver on any Business Day
to the Company at its principal place of business (a) this Warrant, (b) a written
notice in substantially the form of the Subscription Notice attached hereto, of
the Holder's election to exercise this Warrant, which notice shall specify the
number of shares to be purchased (which shall be a whole number of Shares if for
less than all the Shares then issuable hereunder), and (c) payment of the Exercise
Price with respect to such Shares. Such payment may be made by cash, certified
or bank cashier's check or wire transfer in an amount equal to the product of
(i) the Exercise Price times (ii) the number of Warrant Interests as to which
this Warrant is being exercised. 

                  The
Company shall, as promptly as practicable and in any event within seven days after
receipt of such notice and payment, execute and deliver or cause to be executed
and delivered, in accordance with such notice, a certificate or certificates representing
the aggregate number of a share of Common Stock specified in said notice together
with cash in lieu of any fractions of a share of Common Stock as provided in Section
2.5. The certificate or certificates so delivered shall be in such denominations
as may be specified in such notice, and shall be issued in the name of the Holder
or such other name or names as shall be designated in such notice. This Warrant
shall be deemed to have been exercised and such certificate or certificates shall
be deemed to have been issued, and such Holder or any other Person so designated
to be named therein shall be deemed for all purposes to have become a holder of
record of Warrant Shares, as of the date the aforementioned notice and payment
is received by the Company. If this Warrant shall have been exercised only in
part, the Company shall, at the time of delivery of such certificate or certificates,
deliver to the Holder a new Warrant evidencing the right to purchase the remaining
shares of Common Stock called for by this Warrant, which new Warrant shall, in
all other respects be identical with this Warrant, or, at the request of the Holder,
appropriate notation may be made on this Warrant which shall then be returned
to the Holder. The Company shall pay all expenses, stamp, documentary and similar
taxes and other charges payable in connection with the preparation, issuance and
delivery of share certificates and new Warrants under this provision. 

                  2.2
       When Exercise Effective. The
exercise of this Warrant shall be deemed to have been effected immediately prior
to the close of business on the business day on which the Company shall have received
a completed subscription and payment as hereinabove provided, and at such time
the person in whose name any certificate for shares of Common Stock shall be issuable
upon such exercise, as provided in Section 2.1, shall be deemed to have become
the Holder of record of such Common Stock. 

                  2.3
       Company to Reaffirm Obligations.
The Company will, at the time of exercise of this Warrant, upon the request of
the Holder hereof, acknowledge in writing its continuing obligation to afford
to such Holder all rights to which such Holder shall continue to be entitled after
such exercise in accordance with the terms of this Warrant; provided that if the
Holder of this Warrant shall fail to make any such request, such failure shall
not affect the continuing obligation of the Company to afford such rights to such
Holder. 

2

                     2.4
       Shares to Be Fully Paid and Nonassessable.
All shares of Common Stock issued upon the exercise of this Warrant shall be validly
issued, fully paid and nonassessable and, if such Common Stock is then listed
on the American Stock Exchange or any other national securities exchange (as defined
in the Exchange Act) or quoted on NASDAQ, such Common Stock shall, to the extent
permitted under the applicable rules of such exchange or NASDAQ), be duly listed
or quoted thereon, as the case may be. 

                  2.5
       No Fractional Shares Required
to Be Issued. The Company shall not be required to issue fractional shares
of Common Stock upon exercise of this Warrant. If any fraction of a share of Common
Stock would, but for this Section 2.5, be issuable upon final exercise of this
Warrant, in lieu of such fractional share of Common Stock, the Company shall pay
to the Holder in cash an amount equal to the same fraction of the Fair Market
Value of the Company per share of Common Stock outstanding on the Business Day
immediately prior to the date of such exercise. 

                  2.6
       Restrictions. This Warrant is
issued pursuant to an Investment Agreement, dated as of the date hereof, between
the Investor and the Company. All shares of Common Stock issuable upon exercise
of this Warrant shall be subject to the restrictions provided by such Agreement.

 3.               Reservation
of Stock, Etc.The Company will at all times reserve and keep available, solely
for issuance and delivery upon the exercise of the Warrant, all shares of Common
Stock issuable upon the exercise of the Warrant. All shares of Common Stock issued
upon the exercise of the Warrant shall be duly authorized, validly issued, fully
paid and non-assessable. 

4.               Adjustments

                  4.1
        Adjustments for Consolidation, Merger,
Sale of Assets, Reorganization, Etc. In case the Company, after the date hereof,
(a) shall effect a capital reorganization or reclassification of any or all of
its capital stock, or (b) shall consolidate with or merge into any other organization,
company, corporation, partnership, trust, business organization, individual, or
group of individuals (a "Person") and shall not be the continuing or surviving
corporation of such consolidation or merger, or (c) shall permit any other Person
to consolidate with or merge into the Company, and the Company shall be the continuing
or surviving Person but, in connection with such consolidation or merger, the
Common Stock shall be changed into or exchanged for stock or the securities or
property of any other Person, or (d) shall transfer all or substantially all of
its properties and assets to any other Person; then proper provision shall be
made so that the Holder of this Warrant, upon the exercise hereof at any time
after the consummation of such consolidation, merger, transfer, reorganization
or reclassification, shall be entitled to receive the stock and other securities
and property to which such Holder would have been entitled to, as if such Holder
had so exercised this Warrant immediately prior to the consummation of any such
transaction. 

3

                   4.2
        Adjustments for Stock Dividends;
Combinations. In the event that the Company, at any time or from time to time
hereafter, shall (i) declare or pay any dividend on its capital stock payable
in Common Stock; (ii) effect a subdivision of its outstanding shares into a greater
number of shares of Common Stock or any equity securities convertible into Common
Stock (by reclassification or otherwise than by payment of a dividend in Common
Stock); or (iii) combine or consolidate its outstanding shares of Common Stock,
by reclassification or otherwise, into a lesser number of shares of Common Stock,
then, upon the exercise hereof, at any time after the occurrence of any event
described above, the Holder shall be entitled to receive the Common Stock to which
such Holder would have been entitled if such Holder had exercised this Warrant
immediately prior to the occurrence of such event. 

5.              No
Impairment. The Company will not, by any means, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant. Without limiting
the foregoing, the Company (a) will not permit the par value, if any, of any shares
of stock receivable upon the exercise of this Warrant to exceed the amount payable
therefore upon such exercise, (b) will take such action as may be necessary in
order that the Company may validly and legally issue fully paid and non-assessable
shares of Common Stock upon the exercise of this Warrant, and (c) will not (i)
transfer all or substantially all of its assets to any other Person, or (ii) consolidate
with or merge into any other Person where the Company is not the surviving Person,
unless the other Person acquiring such properties and assets or surviving after
such consolidation or merger shall expressly assume in writing all the terms of
this Warrant. 

6.               Transfer
Without Registration. Neither this Warrant nor the shares of Common Stock
issuable hereunder have been registered under the Securities Act of 1933, as amended
(the "1933 Act"), or any state securities laws. Until such time, if any, as such
shares shall have been so registered neither this Warrant nor any shares of Common
Stock issued upon the exercise of this Warrant shall be transferred, sold or assigned,
except upon delivery of (a) an opinion (in form and substance satisfactory to
the Company) of counsel satisfactory to the Company to the effect that such registration
is not required or (b) such information as, in the reasonable opinion of the Company,
is necessary in order to establish that such transfer may be made without registration.
Each certificate for shares of Common Stock issued upon exercise of this Warrant,
unless at the time of exercise such shares are registered under the 1933 Act,
shall bear a legend to such effect. Any certificate issued at any time in exchange
or substitution for any certificate bearing such legend (except a new certificate
issued upon completion of a public offering pursuant to a registration statement
under the 1933 Act) shall also bear such legend unless, in the opinion of counsel
selected by the Holder of such certificate (who may be an employee of such Holder)
and reasonably acceptable to the Company, the securities represented thereby need
no longer be subject to restrictions on resale under the Securities Act. 

4

 7.               Replacement
of Warrants. Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of the Warrant or any Subsequent
Warrant, and receipt of an indemnity reasonably satisfactory to the Company, the
Company at its expense, will execute and deliver a new Warrant of like tenor.

8.               Remedies.
The Company stipulates that the remedies at law of the Holder of this Warrant
in the event of any default or threatened default by the Company in the performance
of or compliance with any of the terms of this Warrant are not and will not be
adequate, and that such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction against
a violation of any of the terms hereof. 

9               Ownership
of Warrant. Until this Warrant or any Subsequent Warrant is transferred on
the books of the Company, the Company may treat the person in whose name such
Warrant is issued as the absolute owner hereof for all purposes notwithstanding
any notice to the contrary, except that if and when this Warrant or any Subsequent
Warrant is properly assigned in blank, the Company may (but shall not be obligated
to) treat the bearer hereof as the absolute owner of such Warrant for all purposes,
notwithstanding any notice to the contrary. The Warrant, if properly assigned,
may be exercised by a new Holder without first having a new Warrant issued. 

10.            Notices,
Etc. All Notices and other communications of the Company to the Holder of
this Warrant shall be mailed by first-class, registered mail, postage prepaid,
at such address as may have been furnished to the Company in writing by such Holder,
or, until an address is so furnished, to and at the address of the last known
Holder of this Warrant. 

11.            Miscellaneous.
All of the terms and conditions hereof shall be binding upon and inure to the
benefit of any Holder of this Warrant or any Subsequent Warrant. This Warrant
and any term hereof may be changed, waived, discharged or terminated only by an
instrument in writing, signed by the party against which enforcement of such change,
waiver, discharge or termination is sought. This Warrant is being delivered in
the State of Connecticut and shall be construed and enforced in accordance with
and governed by the laws of such State. The headings in this Warrant are for purposed
of reference only and shall not limit or otherwise affect the meaning hereof.

12.            Expiration.
The right to exercise this Warrant shall expire at 5:00 p.m., Eastern Time, on
December 30, 2007.
