                             (i) to keep the Shelf Registration Statement

<PAGE>

               that nothing in this subparagraph shall relieve such holder of
               the obligation to return a completed and signed Notice and
               Questionnaire to the Company in accordance with Section 3(a)
               hereof.

               3. Registration Procedures. In connection with the Shelf
Registration Statement, the following provisions shall apply:

                      (a) The Company shall mail the Notice and Questionnaire to
holders of the Series E Preferred Stock, Warrants and Registrable Securities. No
such holder shall be entitled to be named as a selling securityholder in the
Shelf Registration Statement as of the Effective Time, and no such holder shall
be entitled to use the Prospectus for resales of Registrable Securities at any
time unless such holder has returned a completed and signed Notice and
Questionnaire to the Company by the deadline for response set forth therein;
provided, however, such holders shall have at least 10 calendar days from the
date on which the Notice and Questionnaire is first mailed to such holders to
return a completed and signed Notice and Questionnaire to the Company.

                             (i) After the Effective Time, the Company shall,
               upon the request of any holder of Series E Preferred Stock,
               Warrants or Registrable Securities that is not then an Electing
               Holder, promptly send a Notice and Questionnaire to such holder.
               The Company shall not be required to take any action to name such
               holder as a selling securityholder in the Shelf Registration
               Statement or to enable such holder to use the Prospectus for
               resales of Registrable Securities until such holder has returned
               a completed and signed Notice and Questionnaire to the Company.

                             (ii) The term "Electing Holder" shall mean any
               holder of Series E Preferred Stock, Warrants or Registrable
               Securities that has returned a completed and signed Notice and
               Questionnaire to the Company in accordance with Section 3(a)
               hereof.

                      (b) The Company shall furnish to each Electing Holder,
counsel to the Electing Holders, no fewer than five Business Days prior to the
initial filing of the Shelf Registration Statement, a copy of such Shelf
Registration Statement, and shall furnish to such holders, counsel to such
holders, no fewer than two Business Days prior to the filing of any amendment or
supplement to the Prospectus, a copy of such amendment or supplement and shall
use all reasonable efforts to reflect in each such document when so filed with
the Commission such comments as such holders and their respective counsel
reasonably may propose; provided, however, that the Company shall make the final
decision as to the form and content of each such document. If any such Shelf
Registration Statement refers to any Electing Holder by name or otherwise as the
holder of any securities of the Company, then such Electing Holder shall have
the right to require (i) the insertion therein of language, in form and
substance reasonably satisfactory to such Electing Holder, to the effect that
the holding by such Electing Holder of such securities is not to be construed as
a recommendation by such Electing Holder of the investment quality of the
Company's securities covered thereby and that such holding does not imply that
such Electing Holder will assist in meeting any future financial requirements of
the Company or (ii) in the event that such reference to such Electing

                                       5
<PAGE>

Holder by name or otherwise is not required by the Securities Act or any similar
Federal statute then in force, the deletion of the reference to such Electing
Holder in any amendment or supplement to the Registration Statement filed or
prepared subsequent to the time that such reference ceases to be required.

                      (c) From the date hereof until the end of the Effective
Period, the Company shall (subject to paragraph (j) below) promptly take such
action as may be necessary so that (i) each of the Shelf Registration Statement
and any amendment thereto and the Prospectus and any amendment or supplement
thereto (and each report or other document incorporated by reference therein in
each case) complies in all material respects with the Securities Act and the
Exchange Act and the respective rules and regulations thereunder, (ii) each of
the Shelf Registration Statement and any amendment thereto does not, when it
becomes effective, contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading and (iii) each of the Prospectus and any
amendment or supplement to the Prospectus does not at any time during the
Effectiveness Period include an untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

                      (d) The Company shall promptly advise each Electing
Holder, and shall confirm such advice in writing if so requested by any such
holder (which notice pursuant to clauses (ii) through (iv) hereof shall be
accompanied by an instruction to suspend the use of the Prospectus until the
requisite changes have been made):

                             (i) when the Shelf Registration Statement and any
               amendment thereto has been filed with the Commission and when the
               Shelf Registration Statement or any post-effective amendment
               thereto has become effective;

                             (ii) of the issuance by the Commission or any other
               federal or state governmental authority of any stop order
               suspending the effectiveness of the Shelf Registration Statement
               or the initiation of any proceedings for such purpose;

                             (iii) of the receipt by the Company of any
               notification with respect to the suspension of the qualification
               of the securities included in the Shelf Registration Statement
               for sale in any jurisdiction or the initiation of any proceeding
               for such purpose; and

                             (iv) if changes in the Shelf Registration Statement
               or the Prospectus are required in order that the Shelf
               Registration Statement and Prospectus do not contain an untrue
               statement of a material fact and do not omit to state a material
               fact required to be stated therein or necessary to make the
               statements therein (in the case of the Prospectus, in light of
               the circumstances under which they were made) not misleading.

                                       6
<PAGE>

                      (e) The Company shall use its reasonable efforts to
prevent the issuance, and if issued to obtain the withdrawal, of any order
suspending the effectiveness of the Shelf Registration Statement at the earliest
possible time.

                      (f) The Company shall furnish to each requesting Electing
Holder, without charge, at least one copy of the Shelf Registration Statement
and all post-effective amendments thereto, including financial statements and
schedules, and, if such holder so requests in writing, all reports, other
documents and exhibits that are filed with or incorporated by reference in the
Shelf Registration Statement.

                      (g) The Company shall, during the Effectiveness Period,
deliver to each Electing Holder, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) and any amendment or
supplement thereto as such Electing Holder may reasonably request; and the
Company consents (except during the continuance of any event described in
Section 3(d)(iv) above) to the use of the Prospectus and any amendment or
supplement thereto by each of the Electing Holders in connection with the
offering and sale of the Registrable Securities covered by the Prospectus and
any amendment or supplement thereto during the Effectiveness Period.

                      (h) Prior to any offering of Registrable Securities
pursuant to the Shelf Registration Statement, the Company shall (i) register or
qualify or cooperate with the Electing Holders and a single counsel for the
Electing Holders in connection with the registration or qualification of such
Registrable Securities for offer and sale under the securities or "blue sky"
laws of such jurisdictions within the United States as any Electing Holder may
reasonably request, (ii) keep such registrations or qualifications in effect and
comply with such laws so as to permit the continuance of offers and sales in
such jurisdictions for so long as may be necessary to enable any Electing Holder
to complete its distribution of Registrable Securities pursuant to the Shelf
Registration Statement, and (iii) take any and all other actions necessary or
advisable to enable the disposition in such jurisdictions of such Registrable
Securities; provided, however, that in no event shall the Company be obligated
to (A) qualify as a foreign corporation or as a dealer in securities in any
jurisdiction where it would not otherwise be required to so qualify but for this
Section 3(h) or (B) file any general consent to service of process in any
jurisdiction where it is not as of the date hereof so subject.

                      (i) The Company shall cooperate with the Electing Holders
to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold pursuant to the Shelf Registration Statement,
which certificates shall not bear any restrictive legends and shall meet the
requirements of any securities exchange on which the Company's Common Stock is
then listed and which certificates shall be in such permitted denominations and
registered in such names as Electing Holders may request in connection with the
sale of Registrable Securities pursuant to the Shelf Registration Statement.

                      (j) Upon the occurrence of any fact or event contemplated
by paragraph 3(d)(iv) above, the Company shall (subject to the next sentence)
promptly prepare a post-effective amendment or supplement to the Shelf
Registration Statement or the Prospectus, or any document incorporated therein
by reference, or file any other required document so that, as thereafter
delivered to purchasers of the Registrable Securities included therein, the

                                       7
<PAGE>

Prospectus will not include an untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. If the Company
notifies the Electing Holders in accordance with clauses (ii) through (iv) of
paragraph 3(d) above to suspend the use of the Prospectus until the requisite
changes to the Prospectus have been made, then each Electing Holder shall
suspend the use of the Prospectus until (i) such Electing Holder has received
copies of the supplemented or amended Prospectus contemplated by the preceding
sentence or (ii) such Electing Holder is advised in writing by the Company that
the use of the Prospectus may be resumed and has received copies of any
additional or supplemental filings that are incorporated by reference in the
Prospectus. Notwithstanding the foregoing, the Company may suspend the use of
the Prospectus and shall not be required to amend or supplement the Shelf
Registration Statement, any related Prospectus or any document incorporated by
reference, for a period not to exceed the Maximum Delay Period if and so long as
the Delay Conditions exist.

eighteen months after (i) the effective date (as defined in Rule 158(c) under
the Securities Act) of the Shelf Registration Statement, (ii) the effective date
of each post-effective amendment to the Shelf Registration Statement, and (iii)
the date of each filing by the Company with the Commission of an Annual Report
on Form 10-K that is incorporated by reference in the Shelf Registration
Statement, an earnings statement of the Company and its subsidiaries complying
with Section 11(a) of the Securities Act and the Rules and Regulations of the
Commission thereunder (including, at the option of the Company, Rule 158).

                      (l) The Company shall (i) make reasonably available for
inspection by requesting Electing Holders, one counsel, one accountant and any
other agent retained by such holders all relevant financial and other records,
pertinent corporate documents and properties of the Company and its subsidiaries
and (ii) cause the Company's officers, directors and employees to supply all
information reasonably requested by such holders or any such attorney,
accountant or agent in connection with the Shelf Registration Statement, in each
case, as is customary for similar due diligence examinations; provided, however,
that all records, information and documents that are designated in writing by
the Company, in good faith, as confidential shall be kept confidential by such
holders and any such attorney, accountant or agent, unless such disclosure is
made in connection with a court proceeding or required by law, or such records,
information or documents become available to the public generally or through a
third party without an accompanying obligation of confidentiality; and provided,
further, however, that, if the foregoing inspection and information gathering
would otherwise disrupt the Company's conduct of its business, such inspection
and information gathering shall, to the greatest extent possible, be coordinated
on behalf of the requesting Electing Holders and the other parties entitled
thereto by one counsel designated by and on behalf of Electing Holders and other
parties;

                      (m) The Company will use all reasonable efforts to cause
the Securities to be listed on the Nasdaq National Market or other stock
exchange or trading system, if any, on which the Common Stock primarily trades
on or prior to the Effective Time.

                                       8

                      (n) The Company shall use all reasonable efforts to take
all other steps necessary to effect the registration, offering and sale of the
Registrable Securities covered by the Shelf Registration Statement contemplated
hereby.

               4. Registration Expenses.

Statement. The fees and expenses referred to in the foregoing sentence shall

each Electing Holder shall pay the fees and disbursements of any counsel or
other advisors or experts retained by such holders (severally or jointly), other

               directors and each person who controls such Electing Holder
               within the meaning of Section 15 of the Securities Act or Section
               20 of the Exchange Act (each such person being sometimes referred
               to as an "Indemnified Person") against any losses, claims,
               damages or liabilities, joint or several, to which such
               Indemnified Person may become subject under the Securities Act or
               otherwise, insofar as such losses, claims, damages or liabilities
               (or actions in respect thereof) arise out of or are based upon an
               untrue statement or alleged untrue statement of a material fact
               contained in any Shelf Registration Statement or any Prospectus
               contained therein or furnished by the Company to any Indemnified
               Person, or any amendment or supplement thereto, or arise out of
               or are based upon the omission or alleged omission to state
               therein a material fact required to be stated therein or
               necessary to make the statements therein, in light of the
               circumstances in which they were made, not misleading; and

                             (ii) the Company hereby agrees to reimburse such
               Indemnified Person for any legal or other expenses reasonably
               incurred by them in connection with investigating or defending
               any such action or claim as such expenses are incurred; provided,
               however, that the Company shall not be liable to any such
               Indemnified Person in any such case to the extent that any such
               loss, claim, damage or liability arises out of or is based upon
               an untrue statement or alleged untrue statement or omission or
               alleged omission made in such Shelf Registration Statement or
               Prospectus, or amendment or supplement thereto, in reliance upon
               and in conformity with written information relating to such
               Indemnified Person furnished to the Company by or on behalf of
               such Indemnified Person expressly for use therein; provided,
               further, however, that the foregoing indemnity agreement with
               respect to any Prospectus shall not inure to the benefit of any
               Indemnified Person who failed to deliver a final Prospectus or an
               amendment or supplement thereto (provided by the Company to the
               several Indemnified Persons in the requisite quantity and on a
               timely basis to permit proper delivery on or prior to the
               relevant transaction date) to the person asserting any losses,
               claims, damages and liabilities and judgments caused by any
               untrue statement or alleged untrue statement of a material fact
               contained in any Prospectus, or caused by any omission or alleged
               omission to state therein a material fact required to be stated
               therein or necessary to make the statements therein, in light of
               the circumstances under which they were made, not misleading, if
               such material misstatement or omission or alleged material
               misstatement or omission was cured in the final Prospectus or an
               amendment or supplement thereto.

                      (b) Indemnification by the Holders. Each Electing Holder
agrees, as a consequence of the inclusion of any of such holder's Registrable
Securities in any Shelf Registration Statement, severally and not jointly, to
(i) indemnify and hold harmless the Company, its directors, officers who sign
such Shelf Registration Statement and each person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act, against any losses, claims, damages or liabilities to
which the Company or such other persons may become subject, under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in such Shelf
Registration Statement or Prospectus, or any amendment or supplement thereto, or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information relating to such holder furnished to the Company by or on behalf of
such holder expressly for use therein and (ii) reimburse the Company and its
directors and officers who sign such Shelf Registration Statement for any legal
or other expenses reasonably incurred by the Company and such directors and
officers in connection with investigating or defending any such action or claim
as such expenses are incurred.

                      (c) Notices of Claims, Etc.  Promptly after receipt by an
indemnified party under subsection (a) or (b) of this Section 5 of notice of the
commencement of any

                                       10
<PAGE>

action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party under this Section 5, notify such
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party otherwise than under this Section 5. In
case any such action shall be brought against any indemnified party and it shall
notify an indemnifying party of the commencement thereof, such indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, such
indemnifying party shall not be liable to such indemnified party under this
Section 5 for any legal expenses of other counsel or any other expenses, in each
case subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation. No indemnifying
party shall, without the written consent of the indemnified party, which consent
will not be unreasonably withheld, effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action or claim in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an actual or potential
party to such action or claim) unless such settlement, compromise or judgment
(i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act, by
or on behalf of any indemnified party.

                      (d) Contribution. If the indemnification provided for in
this Section 5 is unavailable to or insufficient to hold harmless an indemnified
party under subsection (a) or (b) of this Section 5 in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the indemnifying party and the indemnified
party in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information about such indemnifying party or indemnified party supplied by such
indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 5(d) were determined by
pro rata allocation (even if the Electing Holders were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in this Section 5(d). The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages or liabilities (or actions in respect thereof) referred to above shall
be deemed to include any legal or other fees or expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such

                                       11
<PAGE>

fraudulent misrepresentation. The obligations of the Electing Holders in this
Section 5(d) to contribute shall be several in proportion to the percentage of
Registrable Securities registered by them and not joint.

                      (e) Notwithstanding any other provision of this Section 5,
in no event will any Electing Holder be required to undertake liability to any
person under this Section 5 for any amounts in excess of the dollar amount of
the proceeds to be received by such holder from the sale of such holder's
Registrable Securities (after deducting any fees, discounts and commissions
applicable thereto) pursuant to any Shelf Registration Statement.

                      (f) The obligations of the Company under this Section 5
shall be in addition to any liability that the Company may otherwise have to any
Indemnified Person and the obligations of any Indemnified Person under this
Section 5 shall be in addition to any liability that such Indemnified Person may
otherwise have to the Company. The remedies provided in this Section 5 are not
exclusive and shall not limit any rights or remedies that may otherwise be
available to an indemnified party at law or in equity.

               6. Rule 144.

               The Company agrees, for so long as any Registrable Securities
remain outstanding and during any period in which the Company is subject to
Section 13 of 15 (d) of the Exchange Act, to make all filings required thereby
in a timely manner in order to permit resales of such Registrable Securities
pursuant to Rule 144 of the Securities Act.

               7. Miscellaneous.

                      (a) Remedies. The Company acknowledges and agrees that any
failure by the Company to comply with its obligations under this Agreement may
result in material irreparable injury to the Purchasers or the holders of
Registrable Securities for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, the Purchasers or any holder of Registrable
Securities may obtain such relief as may be required to specifically enforce the
Company's obligations hereunder. The Company further agrees to waive the defense
in any action for specific performance that a remedy at law would be adequate.

                      (b) Other Registration Rights. The Company will not, on or
after the date of this Agreement, enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The Company shall not permit any securities other than the
Registrable Securities to be included in the Shelf Registration Statement other
than 227,500 shares of common stock issuable upon exercise of certain warrants.

                      (c) Amendments and Waivers. The provisions of this
Agreement may not be amended, modified or supplemented, and waivers or consents
to or departures from the provisions hereof may not be given unless (i) in the
case of Section 2 hereof and this Section 7(c)(i), the Company has obtained the
written consent of holders of all outstanding Registrable Securities and (ii) in
the case of all other provisions hereof, the Company has obtained the written
consent of holders of a majority of the Registrable Securities (excluding

                                       12
<PAGE>

Registrable Securities held by the Company or its Affiliates). Notwithstanding
the foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of holders whose Registrable Securities are
being sold pursuant to a Shelf Registration Statement and that does not affect
directly or indirectly the rights of other holders of Registrable Securities may
be given by the holders of a majority of Registrable Securities being sold by
such holders pursuant to such Shelf Registration Statement.

                      (d) Notices. All notices and other communications provided
for or permitted hereunder shall be given as provided in the Securities Purchase
Agreement.

                      (e) Parties in Interest. The parties to this Agreement
intend that all holders of Series E Preferred Stock, Warrants or Registrable
Securities shall be entitled to receive the benefits of this Agreement and that
any Electing Holder shall be bound by the terms and provisions of this Agreement
by reason of such election with respect to the Registrable Securities that are
included in a Shelf Registration Statement. All the terms and provisions of this
Agreement shall be binding upon, shall inure to the benefit of and shall be
enforceable by the respective successors and assigns of the parties hereto and
any holder from time to time of the Series E Preferred Stock, Warrants or
Registrable Securities to the aforesaid extent. In the event that any transferee
of any holder of Series E Preferred Stock, Warrants or Registrable Securities
shall acquire Series E Preferred Stock, Warrants or Registrable Securities, in
any manner, whether by gift, bequest, purchase, operation of law or otherwise,
such transferee shall, without any further writing or action of any kind, be
entitled to receive the benefits of and, if an Electing Holder, be conclusively
deemed to have agreed to be bound by and to perform all of the terms and
provisions of this Agreement to the aforesaid extent.

                      (f) Counterparts. This Agreement may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each
of which when so executed shall be deemed to be an original and all of which
taken together shall constitute one and the same agreement.

                      (g) Headings. The headings in this agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning, construction or interpretation hereof.

                      (h) Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of California without giving
effect to provisions relating to conflicts of law to the extent the application
of the laws of another jurisdiction would be required thereby.

                      (i) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties hereto shall be enforceable to the fullest extent permitted by law.

                                       13
<PAGE>

                      (j) Survival. The respective indemnities, agreements,
representations, warranties and other provisions set forth in this Agreement or
made pursuant hereto shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Electing Holder, any director, officer, partner or controlling person of
such holder, and shall survive the transfer and registration of the Series E
Preferred Stock, Warrants or Registrable Securities of such holder.

                      (k) Entire Agreement. This Agreement is intended by the
parties as a final expression of their agreement and intended to be a complete
and exclusive statement of the agreement and understanding of the parties hereto
in respect of the subject matter hereof. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein,
with respect to the registration rights granted with respect to the Registrable
Securities. This Agreement supersedes all prior agreements and understandings
between the parties with respect to such subject matter.

foregoing correctly sets forth the agreement between the Company and you.

                                     (Date)

               Reference is hereby made to the Registration Rights Agreement
(the "Registration Rights Agreement") between ABAXIS, Inc. (the "Company") and
the Purchasers named therein. Pursuant to the Registration Rights Agreement, the
Company intends to file with the United States Securities and Exchange
Commission (the "Commission") a registration statement on Form S-_ (the "Shelf
Registration Statement") for the registration and resale under Rule 415 of the
Securities Act of 1933, as amended (the "Securities Act"), of up to ____________
shares of the Company's common stock, par value $_______ per share (the
"Securities"). A copy of the Registration Rights Agreement is attached hereto.
All capitalized terms not otherwise defined herein shall have the meanings
ascribed thereto in the Registration Rights Agreement.

               Each beneficial owner of Registrable Securities (as defined
below) is entitled to have the Registrable Securities beneficially owned by it
included in the Shelf Registration Statement. In order to have Registrable
Securities included in the Shelf Registration Statement, this Notice of
Registration Statement and Selling Securityholder Questionnaire ("Notice and
Questionnaire") must be completed, executed and delivered to the Company's
counsel at the address set forth herein for receipt ON OR BEFORE [DEADLINE FOR
RESPONSE]. Beneficial owners of Registrable Securities who do not complete,
execute and return this Notice and Questionnaire by such date (i) will not be
named as selling securityholders in the Shelf Registration Statement and (ii)
may not use the Prospectus forming a part thereof for resales of Registrable
Securities.

               Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and related Prospectus.
Accordingly, holders and beneficial owners of Registrable Securities are advised
to consult their own securities law counsel regarding the consequences of being
named or not being named as a selling securityholder in the Shelf Registration
Statement and related Prospectus.

               The term "Registrable Securities" is defined in the Registration
Rights Agreement to mean (i) any shares of Common Stock issued or issuable upon
the conversion of, or as a dividend with respect to, the Series A Preferred
Stock, (ii) any shares of Common Stock issued or issuable upon exercise of the
Warrants and (iii) any shares of Common Stock that may be issued or distributed
or be issuable in respect of any Registrable Securities by way of conversion,
dividend, stock split or other distribution, merger, consolidation, exchange,
re-

                                       A-1
<PAGE>

capitalization or reclassification or similar transaction; provided, however,
that a security ceases to be a Registrable Security when it is no longer a
Restricted Security

               The term "Restricted Security" is defined in the Registration
Rights Agreement to mean any Security except any such Security that (i) has been
registered pursuant to an effective registration statement under the Securities
Act and sold in a manner contemplated by the Shelf Registration Statement, (ii)
has been transferred in compliance with Rule 144 under the Securities Act (or
any successor provision thereto) or is transferable pursuant to paragraph (k) of
such Rule 144 (or any successor provision thereto), or (iii) has otherwise been
transferred and a new Security not subject to transfer restrictions under the
Securities Act has been delivered by or on behalf of the Company.

                                    ELECTION

               The undersigned holder (the "Selling Securityholder") of

returning this Notice and Questionnaire, agrees to be bound with respect to such

Questionnaire and the Registration Rights Agreement, including without
limitation Section 5 of the Registration Rights Agreement as if the undersigned
Selling Securityholder were an original party thereto.

        may receive discounts, concessions or commissions from the Selling
        Stockholder or the purchaser. Such Registrable Securities may be sold in
        one or more transactions at fixed prices, at prevailing market prices at
        the time of sale, at prices relating to the prevailing market prices at
        the time of sale, at varying prices determined at the time of sale, or

        securities exchange or quotation service on which the Registered
        Securities may be listed or quoted at the time of sale, (ii) in the

        connection with sales of the Registrable Securities or otherwise, the
        Selling Securityholder may enter into hedging transactions with
        broker-dealers or other financial institutions, which may in turn engage
        in short sales of the Registrable Securities in the course of hedging
        the positions they assume. The Selling Securityholder may also sell
        Registrable Securities short and deliver Registrable Securities to close
        out such short positions, or loan or pledge Registrable Securities to
        broker-dealers that in turn may sell such securities.

        State any exceptions here:

                                   DEFINITIONS

               For the purpose of this Questionnaire, the following definitions
apply:

               1. Affiliate. As used in Questions 1 - 7 and Question 9, a person
is an "Affiliate" of a person if such person controls, is controlled by, or is
under common control with, another person. Please assume that an "Affiliate" of
the Company includes without limitation, any 5% stockholder of the Company
(including any person who owns, controls, or holds or holds an option to
acquire, and has the power to vote, 5% or more of the Company's outstanding
voting securities). "Control" is the possession, directly or indirectly, of the
power to direct or cause the direction of the management and policies of an
entity, whether through the ownership of voting securities, by contract or
otherwise.

               As used in Question 8 of this Questionnaire, an "affiliate" of an
NASD member has the following meaning:

               a company which controls, is controlled by or is under common
               control with a member;

               the term affiliate is presumed to include, but is not limited to,
               the following:

                      a company will be presumed to control a member if the
                      company beneficially owns 10% or more of the outstanding
                      voting securities of a member which is a corporation, or
                      beneficially owns a partnership interest in 10% or more of
                      the distributable profits or losses of a member which is a
                      partnership;

                      a member will be presumed to control a company if the
                      member and persons associated with the member beneficially
                      own (i) 10% or more of the outstanding subordinated debt
                      of a company, (ii) 10% or more of the outstanding voting
                      securities of a company which is a corporation or (iii) a
                      partnership interest in 10% or more of the distributable
                      profits or losses of a company which is a partnership;

                      a company will be presumed to be under common control with
                      a member if:

                             the same natural person or company controls both
                             the member and company by beneficially owning 10%
                             or more of the outstanding voting securities of a
                             member or company which is a corporation, or by
                             beneficially owning a partnership interest in 10%
                             or more of the distributable profits or losses of a
                             member or company which is a partnership; or

                                      A-9
<PAGE>

                             a person having the power to direct or cause the
                             direction of the management or policies of the
                             member or the company also has the power to direct
                             or cause the direction of the management or
                             policies of the other entity in question.

                      Beneficial Owner.  A "Beneficial Owner" of a security
includes any person who, directly or indirectly, through any contract,
arrangement, understanding, relationship or otherwise, has or shares voting
power and/or investment power with respect to such security. Voting power
includes "the power to vote, or to direct the voting, of such security" and
investment power includes "the power to dispose, or to direct the disposition,
of such security."

               A person is also a Beneficial Owner of a security if he has the
right to acquire beneficial ownership of such security, at any time within sixty
days, including but not limited to, any right to acquire through: (a) the
exercise of an option, warrant or right, (b) the conversion of a convertible
security, (c) the power to revoke a trust, discretionary account or similar
arrangement, or (d) the automatic termination of a trust, discretionary account
or similar arrangement; provided, however, that if the acquisition of an option,
warrant, right, convertible security or power described in (a), (b) or (c) is
for the purpose of maintaining or obtaining control over the issuer of the
security, the holder of the option, warrant, right, convertible security or
power shall, immediately upon such acquisition and regardless of when it is
exercisable, be deemed a beneficial owner of the underlying securities.

               The possession of the legal power to vote and/or direct the
disposition of securities, absent unusual circumstances, will be sufficient to
confer beneficial ownership. Such power may be held directly, or indirectly,
through one or more controlled entities.

                      Material Relationship. The term "material relationship"
has not been defined by the Securities and Exchange Commission (the "SEC"). The
SEC, however, is likely to construe as material any relationship which tends to
impact arm's length bargaining in dealings with a company, whether arising from
a close business connection, family relationship, a relationship of control or
otherwise. For example, you should conclude that you have such a relationship
with any organization of which you own, directly or indirectly, 10% more of the
outstanding voting stock, or in which you have some other substantial interest,
and with any person or organization with whom you have, or with whom any
relative (or any other person or organization as to which you have any of the
foregoing other relationships) has, a contractual relationship.

                      Member. Rule 0120 of the NASD's Rules of Fair Practice
defines the term "member" to mean any individual, partnership, corporation or
other legal entity admitted to membership in the NASD, and Article l of the
NASD's By-Laws defines the term "person associated with a member" to mean every
sole proprietor, partner, officer, director, or branch manager of any member, or
any natural person occupying a similar status or performing similar functions,
or any natural person engaged in the investment banking or securities business
who is directly or indirectly controlling or controlled by such member (for
example, any employee), whether or not such person is registered or exempt from
registration with the NASD.

this Warrant pursuant to Section 6 hereof.

        2. Definitions. As used in this Warrant, the following terms shall have
the definitions ascribed to them below:

               (a) "Holder" shall mean _____________ or his assigns.

               (b) "Securities" shall mean that __________ shares of the Common
Stock of the Company.

               (c) "Warrant Price" shall be Seven Dollars ($7.00) per share.

exercise of this Warrant or issuable upon conversion of this Warrant.

               (e) "Market Price" of a share of Common Stock means:

                      (i) the average of the daily closing sales prices of the

immediately before the date of determination of Market Price, or

                      (ii) if on any date of determination of Market Price, the
Common Stock shall not be listed on a national securities exchange, the average
of the closing sales price on the

<PAGE>

NASDAQ Stock Market, or, if there shall have been no sales on the NASDAQ Stock
Market on any day, the average of the reported bid and asked prices on the
NASDAQ Stock Market at the end of such day, in each case over the twenty trading
days immediately before the date of determination of Market Price, or

                      (iii) if the Common Stock is not listed on any national
securities exchange or quoted on the NASDAQ Stock Market, the Market Price shall
be deemed to be the fair value thereof calculated as follows:

                             (A) the Company's Board of Directors shall
initially determine in good faith within 7 days the Market Price on the date of
delivery of the applicable notice or request and provide such determination in
writing to the Holder;

                             (B) the Holder shall have 7 business days from the
receipt of such written determination to accept or object to the Market Price as
determined by the Company's Board of Directors. If the Holder objects, the
Market Price shall be determined by an appraiser who shall be an independent
internationally recognized investment banking firm jointly chosen by the Holder
and the Company within 5 business days of the Company's receipt of the Holder's
objection. If the Holder and the Company fail to jointly appoint a sole
appraiser within the specified time, the Market Price shall be the value agreed
upon by an appraiser chosen at random by a mutually agreed upon party from a
group composed of 3 Company nominated appraisers and 3 Holder nominated
appraisers. If the chosen appraiser declines to provide an appraisal, the
process shall be repeated from the group of remaining nominated appraisers. The
compensation, costs, fees and expenses relating to the appraisers and the
related procedures for choosing an appraiser shall be borne equally by the
Holder and the Company.

               (f) "SEC" means the Securities and Exchange Commission.

               (g) "Trading Price" means the closing price per share of an

exercise or conversion of the Warrant and the number of shares to be issued
shall be rounded down to the nearest whole share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying the Holder an amount computed
by multiplying the fractional interest by the fair market value of a full share.

        4. No Shareholder Rights. This Warrant, by itself, as distinguished from
any shares purchased hereunder, shall not entitle its Holder to any of the
rights of a shareholder of the Company.

        5. Reservation of Stock. The Company will reserve from its authorized
and unissued Common Stock a sufficient number of shares to provide for the
issuance of Warrant Stock upon the exercise or conversion of this Warrant.
Issuance of this Warrant shall constitute full authority to the Company's
officers who are charged with the duty of executing stock

                                       2
<PAGE>

certificates to execute and issue the necessary certificates for shares of
Warrant Stock issuable upon the exercise or conversion of this Warrant.

        6. Exercise of Warrant. This Warrant may be exercised by the surrender
of this Warrant, together with the Notice of Exercise and Investment
Representation Statement in the forms attached hereto as Attachments 1 and 2,
respectively, duly completed and executed at the principal office of the
Company, specifying the portion of the Warrant to be exercised and accompanied
by payment in full of the Warrant Price in cash or by check with respect to the
shares of Warrant Stock being purchased. This Warrant shall be deemed to have
been exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above, and the person entitled to receive the
shares of Warrant Stock issuable upon such exercise shall be treated for all
purposes as Holder of such shares of record as of the close of business on such
date. As promptly as practicable after such date, the Company shall issue and
deliver to the person or persons entitled to receive the same a certificate or
certificates for the number of full shares of Warrant Stock issuable upon such
exercise. If the Warrant shall be exercised for less than the total number of
shares of Warrant Stock then issuable upon exercise, promptly after surrender of
the Warrant upon such exercise, the Company will execute and deliver a new
Warrant, dated the date hereof, evidencing the right of the Holder to the
balance of the Warrant Stock purchasable hereunder upon the same terms and
conditions set forth herein.

        7. Conversion. In lieu of exercising this Warrant or any portion hereof,
the Holder hereof shall have the right to convert this Warrant or any portion
hereof into Warrant Stock by executing and delivering to the Company at its
principal office the written Notice of Conversion and Investment Representation
Statement in the forms attached hereto as Attachments 2 and 3, specifying the
portion of the Warrant to be converted, and accompanied by this Warrant. The
number of shares of Warrant Stock to be issued to Holder upon such conversion
shall be computed using the following formula:

                                X = (P)(Y)(A-B)/A

               X = the number of shares of Securities to be issued to the
                   Holder for the portion of the Warrant being converted.

                      P  =  the portion of the Warrant being converted expressed
                            as a decimal fraction.

                      Y  =  the total number of shares of Securities issuable
                            upon exercise of the Warrant in full.

                      A  =  the Market Price.

<PAGE>

                      B  =  the Warrant Price on the date of conversion.

        Any portion of this Warrant that is converted shall be immediately
canceled. This Warrant or any portion hereof shall be deemed to have been
converted immediately prior to the close of business on the date of its
surrender for conversion as provided above, and the person entitled to receive
the shares of Warrant Stock issuable upon such conversion shall be treated for
all purposes as Holder of such shares of record as of the close of business on
such date. As promptly as practicable after such date, the Company shall issue
and deliver to the person or persons entitled to receive the same a certificate
or certificates for the number of full shares of Warrant Stock issuable upon
such conversion. If the Warrant shall be converted for less than the total
number of shares of Warrant Stock then issuable upon conversion, promptly after
surrender of the Warrant upon such conversion, the Company will execute and
deliver a new Warrant, dated the date hereof, evidencing the right of the Holder
to the balance of the Warrant Stock purchasable hereunder upon the same terms
and conditions set forth herein.

        8. Adjustment of Exercise Price and Number of Shares. The number of
shares issuable upon exercise of this Warrant (or any shares of stock or other
securities or property at the time receivable or issuable upon exercise of this
Warrant) and the Warrant Price therefor are subject to adjustment upon the
occurrence of the following events:

               (a) Adjustment for Stock Splits, Stock Dividends,
Recapitalizations, etc. The Warrant Price and the number of shares issuable upon
exercise of this Warrant shall each be proportionally adjusted to reflect any
stock dividend, stock split, reverse stock split, combination of shares,
reclassification, recapitalization or other similar event altering the number of
outstanding shares of the Company's capital stock.

               (b) Adjustment for Other Dividends and Distributions. In case the
Company shall make or issue, or shall fix a record date for the determination of
eligible holders entitled to receive, a dividend or other distribution with
respect to the shares payable in securities of the Company then, and in each
such case, the Holder, on exercise of this Warrant at any time after the
consummation, effective date or record date of such event, shall receive, in
addition to the Warrant Stock (or such other stock or securities) issuable on
such exercise prior to such date, the securities of the Company to which such
Holder would have been entitled upon such date if such Holder had exercised this
Warrant immediately prior thereto (all subject to further adjustment as provided
in this Warrant).

        9. Adjustment for Capital Reorganization, Consolidation, Merger. If any
capital reorganization of the capital stock of the Company, or any consolidation
or merger of the Company with or into another corporation, or the sale of all or
substantially all of the Company's assets to another corporation shall be
effected in such a way that holders of the Company's capital stock will be
entitled to receive stock, securities or assets with respect to or in exchange
for the Company's capital stock, and in each such case the Holder, upon the
exercise of this Warrant, at any time after the consummation of such capital
reorganization, consolidation, merger, or sale, shall be entitled to receive, in
lieu of the stock or other securities and property receivable upon the exercise
of this Warrant prior to such consummation, the stock or other

                                       4
<PAGE>

securities or property to which such Holder would have been entitled upon such
consummation if such Holder had exercised this Warrant immediately prior to the
consummation of such capital reorganization, consolidation, merger, or sale, all
subject to further adjustment as provided in this Section 9; and in each such
case, the terms of this Warrant shall be applicable to the shares of stock or
other securities or property receivable upon the exercise of this Warrant after
such consummation.

        10. Transfer of Warrant. This Warrant may be transferred or assigned by
the Holder hereof in whole or in part, provided that the transferor provides, at
the Company's request, an opinion of counsel satisfactory to the Company that
such transfer does not require registration under the Act and the securities law
applicable with respect to any other applicable jurisdiction.

        11. Termination. This Warrant shall terminate and no longer be
exercisable at 5:00 p.m. California time, on March ____, 2007.

        12. Miscellaneous. This Warrant shall be governed by the laws of the
State of California, as such laws are applied to contracts to be entered into
and performed entirely in California by California residents. The headings in
this Warrant are for purposes of convenience and reference only, and shall not
be deemed to constitute a part hereof. Neither this Warrant nor any term hereof
may be changed or waived orally, but only by an instrument in writing signed by
the Company and the Holder of this Warrant. All notices and other communications
from the Company to the Holder of this Warrant shall be delivered personally or
mailed by first class mail, postage prepaid, to the address furnished to the
Company in writing by the last Holder of this Warrant who shall have furnished
an address to the Company in writing, and if mailed shall be deemed given three
days after deposit in the United States mail.

                       INVESTMENT REPRESENTATION STATEMENT

                            Shares of the Securities
                     (as defined in the attached Warrant) of
                                  ABAXIS, INC.

In connection with the purchase of the above-listed securities, the undersigned
hereby represents to Abaxis, Inc. (the "Company") as follows:

        (a) The securities to be received upon the exercise of the Warrant (the
"Securities") will be acquired for investment for its own account, not as a
nominee or agent, and not with a view to the sale or distribution of any part
thereof, and the undersigned has no present intention of selling, granting
participation in or otherwise distributing the same, but subject, nevertheless,
to any requirement of law that the disposition of its property shall at all
times be within its control. By executing this Statement, the undersigned
further represents that it does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer, or grant participation to such
person or to any third person, with respect to any Securities issuable upon
exercise of the Warrant.

        (b) The undersigned understands that the Securities issuable upon
exercise of the Warrant at the time of issuance may not be registered under the
Act, and applicable state securities laws, on the ground that the issuance of
such securities is exempt pursuant to Section 4 (2) of the Act and state law
exemptions relating to offers and sales not by means of a public offering, and
that the Company's reliance on such exemptions is predicated on the
undersigned's representations set forth herein.

        (c) The undersigned agrees that in no event will it make a disposition
of any Securities acquired upon the exercise of the Warrant unless and until (i)
it shall have notified the Company of the proposed disposition and shall have
furnished the Company with a statement of the circumstances surrounding the
proposed disposition, and (ii) it shall have furnished the Company with an
opinion of counsel satisfactory to the Company and Company's counsel to the
effect that (A) appropriate action necessary for compliance with the Act and any
applicable state securities laws has been taken or an exemption from the
registration requirements of the Act and such laws is available, and (B) the
proposed transfer will not violate any of said laws.

        (d) The undersigned acknowledges that an investment in the Company is
highly speculative and represents that it is able to fend for itself in the
transactions contemplated by this Statement, has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of its investments, and has the ability to bear the economic risks
(including the risk of a total loss) of its investment. The undersigned
represents that it has had the opportunity to ask questions of the Company
concerning the Company's business and assets and to obtain any additional
information which it considered necessary to verify the accuracy of or to
amplify the Company's disclosures, and has had all questions which have been
asked by it satisfactorily answered by the Company.

                                       7

        (e) The undersigned acknowledges that the Securities issuable upon
exercise of the Warrant must be held indefinitely unless subsequently registered
under the Act or an exemption from such registration is available. The
undersigned is aware of the provisions of Rule 144 promulgated under the Act
which permit limited resale of shares purchased in a private placement subject
to the satisfaction of certain conditions, including, among other things, the
existence of a public market for the shares, the availability of certain current
public information about the Company, the resale occurring not less than one
year after a party has purchased and paid for the security to be sold, the sale
being through a "broker's transaction" or in transactions directly with a
"market makers" (as provided by Rule 144(f)) and the number of shares being sold
during any three-month period not exceeding specified limitations.
