                          CERTIFICATE OF DETERMINATION
                               OF PREFERENCES OF
                          SERIES A PREFERRED STOCK OF
                                  ABAXIS, INC.
                            A California corporation


         Clinton H. Severson and Ting W. Lu certify that:

         1.      They are the duly elected and acting President and Secretary,
respectively, of said Corporation.

         2.      Pursuant to authority given by said Corporation's Articles of
Incorporation, the Board of Directors of said Corporation has duly adopted the
following recitals and resolutions:

         WHEREAS, the Articles of Incorporation of the Corporation provide for
a class of its authorized shares known as Preferred Stock, comprising Five
Million (5,000,000) shares issuable from time to time in one or more series;

         WHEREAS, the Board of Directors of this Corporation is authorized to
fix the number of shares of any series of Preferred Stock; to determine the
designation of any such series, and to determine or alter the rights,
preferences, privileges, and restrictions granted to or imposed upon any wholly
unissued series of Preferred Stock including but not limited to the dividend
rights, dividend rate and conversion rights, and to fix, alter or reduce the
number of shares constituting any such series (but not below the number of
shares then outstanding); and

         WHEREAS, it is the desire of the Board of Directors of the
Corporation, pursuant to its authority under the Articles of Incorporation, to
fix the rights, preferences, privileges, restrictions and other matters
relating to a series of Preferred Stock to be designated Series A Preferred
Stock;

         NOW, THEREFORE, BE IT RESOLVED, that the Board of Directors does
hereby provide for the issue of a new series of Preferred Stock of the
Corporation and does hereby fix the rights, preferences, privileges,
restrictions and other matters relating to such series of Preferred Stock as
follows:


         1.      Designation.  There shall be a series of Preferred Stock,
which shall comprise Five Hundred Thousand (500,000) shares and shall be
designated "Series A Preferred Stock."  As used hereafter, the terms "Preferred
Stock" and "Preferred Shares" without designation shall refer to shares of
Series A Preferred Stock.





                                       1
   2

         2.      Dividends.  The holder of record of a share of Series A
Preferred Stock on the 90th day after the first date the Corporation issues
Series A Preferred Stock (the date of issuance hereinafter referred to as the
"Issuance Date") shall be entitled to receive, out of any assets at the time
legally available therefor, a dividend of $0.15 per share of Series A Preferred
Stock.  The holder of record of a share of Series A Preferred Stock on the
180th day after the Issuance Date shall be entitled to receive, out of any
assets at the time legally available therefor, a dividend of $0.15 per share of
Series A Preferred Stock.  The holder of record of a share of Series A
Preferred Stock on the 270th day after the Issuance Date shall be entitled to
receive, out of any assets at the time legally available therefor, a dividend
of $0.15 per share of Series A Preferred Stock.  The right to the dividends on
the Series A Preferred Stock described in the preceding three sentences shall
be cumulative.  The Corporation will pay such dividends either in cash or by
issuing shares of the Corporation's Common Stock ("Common Stock") having the
Market Value (as defined below) equal to such dividends, at the option of the
Board of Directors of the Corporation.  If the Corporation elects to pay such
dividends by issuing Common Stock, the "Market Value" of such Common Stock will
be the average of the closing sale prices of the Corporation's Common Stock as
reported on the Nasdaq National Market for the five (5) trading days prior to
the record date for such dividend.  A holder of Series A Preferred Stock who
would otherwise be entitled to receive a fraction of a share of Common Stock
under this Section 2 (taking into account all shares of Series A Preferred
Stock held by such holder) shall receive, in lieu thereof, an amount equal to
the product of such fractional interest multiplied by the Market Value.  No
dividends or distributions shall be made with respect to the Common Stock
unless at the same time an equivalent dividend with respect to the Series A
Preferred Stock has been paid or declared and set apart for payment.

         3.      Conversion Rights.  The holders of Series A Preferred Stock
shall have conversion rights as follows:

                 a.       Right to Convert.  Each share of Series A Preferred
shall be convertible, at the option of the holder thereof, at any time after
the 45th day after the Issuance Date, at the office of the Corporation or any
transfer agent for the Series A Preferred, into Common Stock as more fully
described below.  The number of shares of fully paid and nonassessable Common
Stock into which each share of Series A Preferred may be converted shall be
determined by dividing Ten Dollars ($10.00) by the Series A Conversion Price
(as hereinafter defined) in effect at the time of conversion.  The Series A
Conversion Price shall be the lesser of (i) the Purchase Date Price (as defined
below) and (ii):

                          A.      In the event the holder converts between
forty-six (46) days and ninety (90) days after the Issuance Date, eighty
percent (80%) of the Market Price (as defined below);

                          B.      In the event the holder converts between
ninety one (91)



                                       2
   3
days and one hundred twenty (120) days after the Issuance Date, seventy-eight
percent (78%) of the Market Price;

                          C.        In the event the holder converts between
one hundred twenty one (121) days and one hundred fifty (150) days after the
Issuance Date, seventy-six percent (76%) of the Market Price;

                          D.        In the event the holder converts between
one hundred fifty one (151) days and one hundred eighty (180) days after the
Issuance Date, seventy-four percent (74%) of the Market Price;

                          E.        In the event the holder converts between
one hundred eighty one (181) days and two hundred ten (210) days after the
Issuance Date, seventy-three percent (73%) of the Market Price;

                          F.        In the event the holder converts between
two hundred eleven (211) days and two hundred forty (240) days after the
Issuance Date, seventy-two percent (72%) of the Market Price; and

                          G.        In the event the holder converts anytime
after two hundred forty one (241) days after the Issuance Date, seventy-one
percent (71%) of the Market Price.

                 For purposes of this Section 3, "Purchase Date Price" shall be
the closing sales price of the Common Stock as reported on the Nasdaq National
Market on September 9, 1996.  For purposes of this Section 3, "Market Price"
shall be the average of the closing bid prices of the Common Stock as reported
on the Nasdaq National Market for the five (5) trading days prior to the date
the Corporation receives written notice by telecopy from the holder of Series A
Preferred Stock that such holder elects to convert Series A Preferred Stock, as
adjusted to reflect any stock dividends on, or stock splits or stock
combinations of, the Common Stock since the Issuance Date.

                 b.       Automatic Conversion.    Each share of Series A
Preferred Stock shall be converted into Common Stock automatically upon the
earlier to occur of (i) the time the consent of at least a majority of the
outstanding Series A Preferred Stock to such conversion is obtained or (ii) on
the second anniversary of the Issuance Date.

                 c.       No Fractional Shares.  No fractional shares of common
stock or script shall be issued upon conversion of shares of Series A Preferred
Stock.  If more than one share of Series A Preferred Stock shall be surrendered
for conversion at any one time by the same holder, the number of full shares of
common stock issuable upon conversion thereof shall be computed on the basis of
the aggregate number of shares of Series A Preferred Stock so surrendered.
Instead of any fractional shares of common stock which would otherwise be
issuable upon conversion of any shares of Series A Preferred Stock,












                                       3
   4
the Corporation shall pay a cash adjustment in respect of such fractional
interest equal to the product of such fractional interest multiplied by the
Market Price relevant to such conversion.

                 d.       Mechanics of Conversion.  Before any holder of
Preferred Stock shall be entitled to convert the same into Common Stock, such
holder shall surrender the certificate or certificates therefor, duly endorsed
in blank or accompanied by proper instruments of transfer, at the principal
office of the Corporation or of any transfer agent for the Preferred Stock, and
shall give written notice to the Corporation at such office that such holder
elects to convert the same and shall state in writing therein the name or names
in which such holder wishes the certificate or certificates for Common Stock to
be issued.  As soon as practicable thereafter, the Corporation shall issue and
deliver at such office to such holder's nominee or nominees, certificates for
the number of whole shares of Common Stock to which such holder shall be
entitled.  Such conversion shall be deemed to have been made as of the date of
such surrender of the Preferred Stock to be converted, and the person or
persons entitled to receive the Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such
Common Stock on said date.

                 e.       Capital Adjustments.  In case the Corporation shall
at any time (A) subdivide the outstanding Common Stock, or (B) issue a stock
dividend on its outstanding Common Stock, the number of shares of Common Stock
issuable upon conversion of the Preferred Stock immediately prior to such
subdivision or the issuance of such stock dividend shall be proportionately
increased by the same ratio as the subdivision or dividend (with appropriate
adjustments in the Series A Conversion Price).  In case the Corporation shall
at any time combine its outstanding Common Stock, the number of shares of
Common Stock issuable upon conversion of the Preferred Stock immediately prior
to such combination shall be proportionately decreased by the same ratio as the
combination (with appropriate adjustments in the Series A Conversion Price).
All such adjustments described herein shall be effective at the close of
business on the date of such subdivision, stock dividend or combination, as the
case may be.

                 f.       Reorganization.  In case of any capital
reorganization (other than in connection with a merger or other reorganization
in which the Corporation is not the continuing or surviving entity) or any
reclassification of the Common Stock of the Corporation, the Preferred Stock
shall thereafter be convertible into that number of shares of stock or other
securities or property to which a holder of the number of shares of Common
Stock of the Corporation deliverable upon conversion of the shares of Preferred
Stock immediately prior to such reorganization or recapitalization would have
been entitled upon such reorganization or reclassification.  In any such case,
appropriate adjustment (as determined by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the
rights and interests thereafter of the holders of Preferred Stock, such that
the provisions set forth herein shall thereafter be applicable, as nearly as
reasonably may be, in relation to any share of stock or other













                                       4
   5
property thereafter deliverable upon the conversion.

                 h.       Reservation of Stock.  The Corporation shall at all
times reserve and keep available, out of its authorized but unissued Common
Stock, solely for the purpose of effecting the conversion of the Preferred
Stock, the full number of shares of Common Stock deliverable upon the
conversion of all Preferred Stock from time to time outstanding.  The
Corporation shall from time to time (subject to obtaining necessary director
and shareholder action), in accordance with the laws of the State of
California, increase the authorized amount of its Common Stock if at any time
the authorized number of shares of Common Stock remaining unissued shall not be
sufficient to permit the conversion of all of the shares of Preferred Stock at
the time outstanding.

         4.      Voting Rights.  Except as otherwise required by law, each
holder of shares of Series A Preferred Stock shall be entitled to the number of
votes for the Series A Preferred Stock held by him as shall be equal to the
whole number of shares of Common Stock into which all of such shares of Series
A Preferred Stock could be converted immediately after the close of business on
the record date for the vote or consent of shareholders and shall have voting
rights and powers equal to the voting rights and powers of the Common Stock.
The holder of each share of Series A Preferred Stock shall be entitled to
notice of any shareholders' meeting in accordance with the Bylaws of the
Corporation and shall vote with holders of the Common Stock upon any matter
submitted to a vote of shareholders, except those matters required by law to be
submitted to a class vote.

         RESOLVED FURTHER, that the President or any Vice President, and the
Secretary or any Assistant Secretary, of the Corporation be, and hereby are,
authorized and directed to execute, acknowledge, file and record a Certificate
of Determination of preferences in accordance with the foregoing resolutions
and the provisions of California law.

         3.      The authorized number of shares of Series A Preferred Stock is
500,000, none of which have been issued.

                           CERTIFICATE OF CORRECTION
                                       OF
                          CERTIFICATE OF DETERMINATION
                               OF PREFERENCES OF
                          SERIES A PREFERRED STOCK OF
                                  ABAXIS, INC.
                            A California corporation


         Clinton H. Severson and Ting W. Lu certify that:

         1.      They are the duly elected and acting President and Secretary,
respectively, of said Corporation.

         2.      The Corporation filed with the Secretary of State of the State
of California on September 6, 1996 a Certificate of Determination of Series A
Preferred Stock of Abaxis, Inc. (the "Certificate of Determination").

         3.      The Certificate of Determination incorrectly stated the
resolution adopted by the Board of Directors of the Corporation.  Specifically,
the last sentence in subsection 3(a) ("Conversion Rights") incorrectly stated
that "For purposes of this Section 3, "Market Price" shall be the average of
the closing sales prices of the Common Stock as reported on the Nasdaq National
Market for the five (5) trading days prior to the date of conversion of the
Series A Preferred Stock, as adjusted to reflect any stock dividends on, or
stock splits or stock combinations of, the Common Stock since the Issuance
Date."  In fact, this sentence read as follows in the resolution adopted by the
Board of Directors of the Corporation: "For purposes of this Section 3, "Market
Price" shall be the average of the closing bid prices of the Common Stock as
reported on the Nasdaq National Market for the five (5) trading days prior to
the date of conversion of the Series A Preferred Stock, as adjusted to reflect
any stock dividends on, or stock splits or stock combinations of, the Common
Stock since the Issuance Date."

         4.      Accordingly, subsection 3(a) of the Certificate of
Determination is corrected to read in full as follows:

                 a.       Right to Convert.  Each share of Series A Preferred
shall be convertible, at the option of the holder thereof, at any time after
the 45th day after the Issuance Date, at the office of the Corporation or any
transfer agent for the Series A Preferred, into Common Stock as more fully
described below.  The number of shares of fully paid and nonassessable Common
Stock into which each share of Series A Preferred may be converted shall be
determined by dividing Ten Dollars ($10.00) by the Series A Conversion Price
(as hereinafter defined) in effect at the time of conversion.  The Series A
Conversion Price shall be the lesser of (i) the Purchase Date Price (as defined
below) and (ii):

            A.      In the event the holder converts between forty-six (46) days





   8
and ninety (90) days after the Issuance Date, eighty percent (80%) of the
Market Price (as defined below);

                          B.        In the event the holder converts between
ninety one (91) days and one hundred twenty (120) days after the Issuance Date,
seventy-eight percent (78%) of the Market Price;

                          C.        In the event the holder converts between
one hundred twenty one (121) days and one hundred fifty (150) days after the
Issuance Date, seventy-six percent (76%) of the Market Price;

                          D.        In the event the holder converts between
one hundred fifty one (151) days and one hundred eighty (180) days after the
Issuance Date, seventy-four percent (74%) of the Market Price;

                          E.        In the event the holder converts between
one hundred eighty one (181) days and two hundred ten (210) days after the
Issuance Date, seventy-three percent (73%) of the Market Price;

                          F.        In the event the holder converts between
two hundred eleven (211) days and two hundred forty (240) days after the
Issuance Date, seventy-two percent (72%) of the Market Price; and

                          G.        In the event the holder converts anytime
after two hundred forty one (241) days after the Issuance Date, seventy-one
percent (71%) of the Market Price.

                 For purposes of this Section 3, "Purchase Date Price" shall be
the closing sales price of the Common Stock as reported on the Nasdaq National
Market on September 9, 1996.  For purposes of this Section 3, "Market Price"
shall be the average of the closing bid prices of the Common Stock as reported
on the Nasdaq National Market for the five (5) trading days prior to the date
of conversion of the Series A Preferred Stock, as adjusted to reflect any stock
dividends on, or stock splits or stock combinations of, the Common Stock since
the Issuance Date.

         5.      This Certificate of Correction does not alter the wording of
any resolution or written consent which was in fact adopted by the Board of
Directors of the Corporation.

         Clinton H. Severson and Ting W. Lu certify that:

         1.      They are, respectively, the President and Secretary of Abaxis,
Inc., a California corporation.

         2.      Paragraph (a) of Article III of the Amended and Restated
