EXHIBIT A

                                  IMMUCOR, INC.
                             1998 STOCK OPTION PLAN


     1. Purpose.  This 1998 STOCK OPTION PLAN (the "Plan") has been  established
by Immucor,  Inc.,  a Georgia  corporation  (the  "Company"),  to secure for the
Company and its  shareholders  the benefits arising from capital stock ownership
by those who will  contribute to its future growth and  continued  success.  The
Plan will provide a means whereby such persons may purchase shares of the common
stock, $0.10 par value, of the Company ("Common Stock") pursuant to options.

     2. Administration.

     (a) The authority to manage and control the operation and administration of
the Plan shall be vested in a committee (the  "Committee") of at least three (3)
members of the Board of  Directors  to be appointed at the pleasure of the Board
of Directors of the Company.

     (b) The  Committee  shall be subject  in all  respects  to the  supervisory
prerogative of the Board of Directors of the Company. To the extent permitted by
applicable  law,  the powers of the  Committee  may be exercised by the Board of
Directors,  in which case the references to the Committee  shall be construed to
apply equally to the Board of Directors.

     (c) The Committee  shall have the power to interpret and apply the Plan and
to make regulations for carrying out its purpose. Any interpretation of the Plan
by the  Committee  and any  decision  made by the  Committee on any other matter
relating to the Plan shall be final and binding on all persons.

     (d)  No  member  of the  Committee  shall  be  liable  for  any  action  or
determination made in good faith and permitted by the terms of the Plan.

     3.  Participation.  Subject to the terms of the Plan,  the Committee  shall
determine  and  designate,  from time to time,  employees  and  directors of the
Company to whom  options are to be granted (the  "Participants"),  the number of
shares  of Common  Stock  that  shall be  subject  to  options  granted  to each
Participant,  the  terms and  conditions  of each  option,  and the  voting  and
transfer  restrictions,  if any, to which the shares of Common Stock  obtainable
upon exercise of each option shall be subject.

     4. Shares  Subject to the Plan.  The shares of stock that may be subject to
options  under the Plan  shall be shares of Common  Stock,  and may  consist  of
either  unissued  shares or shares  held in the  treasury  of the  Company.  The
aggregate  number of shares of Common  Stock for which  options  may be  granted
under the Plan shall not exceed One Million Shares (1,000,000)  shares,  subject
to such  adjustments as may take place in accordance  with Section 12. If, as to
any  number of  shares,  any  option  granted  pursuant  to the Plan  expires or
terminates  while the Plan remains in effect,  such number of shares shall again
be available for grant under the Plan.

     5.  Option  Price.  The  price  at  which a share of  Common  Stock  may be
purchased pursuant to the exercise of an option under the Plan shall be fixed by
the Committee on the date the option is granted.

     6. Option  Expiration Date. The "Expiration Date" with respect to an option
granted  to a  Participant  under  the Plan  means the date  established  by the
Committee as the date after which the option is not exercisable.

     7. Exercise of Option.

     (a) Each  option  shall be  exercisable  at such  time or times as shall be
established  hereunder.  The Committee  may, in its  discretion,  accelerate the
exercisability  of any one or more  options  at any time and for any  reason.  A
Participant  may  exercise an option by giving  written  notice  (the  "Exercise
Notice")  thereof prior to the option's  Expiration Date to the Secretary of the
Company at the Company's corporate headquarters.

     (b) The  full  purchase  price  of the  shares  purchased  pursuant  to the
exercise  of an  option  shall be paid in cash or check  or by  tender  of stock
certificates in proper from for transfer to the Company  representing  shares of
Common Stock valued at the last sales price of the Common Stock on the preceding
business  day as reported on the  National  Association  of  Securities  Dealers
Automated  Quotation  System (NASDAQ)  National Market System,  or any successor
system,  or by any  combination  of the  foregoing,  contemporaneously  with the
giving of the Exercise  Notice.  The Committee also may accept in payment of all
or part of the purchase price a promissory note of the Participant.  In addition
to payment of the full price,  the  Participant  shall pay to the Company at the
time of exercise,  or shall  otherwise  make  arrangements  satisfactory  to the
Committee  regarding  payment of, any additional amount that the Committee deems
necessary to satisfy the Company's liability to withhold federal, state or local
income or other taxes incurred by reason of exercise of the option.

     8.  Termination of Employment.  The Committee may specify,  with respect to
the  options  granted  to any  particular  Optionee  who is an  employee  of the
Company,  the effect  upon such  Optionee's  right to  exercise an option of the
termination of such Optionee's  employment  under various  circumstances,  which
effect may include  immediate or deferred  termination of such Optionee's rights
under an option, or acceleration of the date at which an option may be exercised
in full.

     9. Compliance With Applicable Laws.  Notwithstanding any other provision of
the Plan, the Company shall not be obligated to issue any shares of Common Stock
under the Plan unless such issuance is in compliance  with all  applicable  laws
and any applicable  requirements of any securities  exchange on which the Common
Stock is traded.  Prior to the  issuance of any shares of Common Stock under the
Plan, the Company may require a written statement from the recipient as evidence
of such compliance, including, in some cases, an acknowledgment by the recipient
that the  recipient  is  acquiring  the  shares for  investment  and not for the
purpose or with the intention of distributing the shares.

     10.  Transferability  and  Restrictions  Upon Transfer and Voting.  Options
under the Plan are not transferable  except by will or under the laws of descent
and  distribution.   Options  may  be  exercised  during  the  lifetime  of  the
Participant  only by the  Participant.  Shares of  Common  Stock  received  upon
exercise  of options  granted  under the Plan may be subject to such  voting and
transfer restrictions as the Committee in its sole discretion shall establish at
the time such options are granted.  If the transfer or voting of shares obtained
upon exercise of an option is restricted,  certificates representing such shares
may bear a legend referring to such restrictions.

     11. Employment and Shareholder  Status.  This Plan, any document describing
this Plan, the grant of any option hereunder,  and any agreement  evidencing the
grant of such option shall not be construed to give any Participant or any other
person a right to  employment  or continued  employment by the Company or affect
the right of the Company to terminate the  employment of any such person with or
without  cause.  The grant of an option under the Plan shall not confer upon the
holder thereof any right as a shareholder of the Company.  No person entitled to
exercise  any  option  granted  under the Plan  shall  have any of the rights or
privileges of a shareholder of record with respect to any shares of Common Stock
issuable  upon  exercise  of such  option  until such  option is  exercised  and
certificates representing such shares have been issued and delivered.

     12. Adjustments and Ownership Changes.

     (a) In the event of any change in the outstanding shares of Common Stock by
reason of any stock dividend, stock split, or similar corporate change involving
the Common  Stock,  the aggregate  number and kind of shares  subject to options
outstanding or to be granted under the Plan shall be proportionately adjusted or
modified,  and the terms of any outstanding option shall be adjusted or modified
accordingly.

     (b) Unless  otherwise  provided  in the  Option  Agreement  (as  defined in
Section 13 hereof), in the event of any merger,  consolidation,  reorganization,
division or other  corporate  transaction in which the Common Stock is converted
into another security or into the right to receive securities or property of the
Company or of any other entity (an "Ownership  Change"),  the Company shall have
the right, at its  discretion,  to provide for the assumption or substitution of
comparable stock options in place of the options theretofore granted hereunder.

     (c) Unless  otherwise  provided  in the  Option  Agreement  (as  defined in
Section  13  hereof),  in the event such an  Ownership  Change  takes  place and
provision is not made for such assumption or substitution,  or in the event that
the  Company  sells all or  substantially  all of its  assets,  or  engages in a
liquidation of all or substantially  all of its assets (a "Termination  Event"),
the Committee may, in its discretion,  accelerate the  exercisability of any one
or more  options in  accordance  with Section 7. It is the policy of the Company
that the  decision  whether to  accelerate  the  exercisability  of  outstanding
options take into account such factors as the  profitability  of the transaction
giving rise to the Termination  Event to the  shareholders  of the Company,  the
likelihood  that the business of the Company will  substantially  continue under
the same, different or changed ownership following such transaction,  the tenure
and performance of individual Participants,  the possibility that some or all of
the  Participants  receive or are invited to  participate in benefits or benefit
plans if they continue as employees of the  successor to the Company's  business
or other  consideration  in  connection  with  such  transaction,  and any other
factors that may be  appropriate  within the scope of their  business  judgment.
Whether or not such an  acceleration  occurs,  all  outstanding  exercisable and
non-exercisable  options shall be canceled to the extent they remain unexercised
at the time such transaction is consummated.

     (d) In no event  shall any  fraction of a share of stock be issued upon the
exercise of an option.

     13.  Agreement  With  Company.  At the  time of a grant of an  option,  the
Committee shall require a Participant to enter into a written agreement with the
Company in a form  specified  by the  Committee  (the "Option  Agreement").  The
Option  Agreement  shall  reflect the  Participant's  agreement to the terms and
conditions  of the  Plan  and to  such  additional  terms  and  conditions,  not
inconsistent  with the  Plan,  as the  Committee  may,  in its sole  discretion,
prescribe. No option purported to be granted pursuant to the Plan shall be valid
or binding on the Company unless  evidenced by an Option  Agreement  approved by
the Committee.

     14.  Amendment  and  Termination  of Plan.  The Board of  Directors  of the
Company may at any time amend,  suspend or  terminate  the Plan.  No  amendment,
suspension  or  termination  of the Plan  (other  than in  connection  with such
actions as are  expressly  authorized  in the Plan)  shall  adversely  affect or
impair any option  previously  granted under the Plan without the consent of the
holder thereof.

                          OPTION AGREEMENT - 1998 PLAN


     THIS OPTION AGREEMENT (this "Agreement"),  dated as of Month, Day, 199X, is
by and between IMMUCOR,  INC., a Georgia  corporation (the "Company"),  and (the

     WHEREAS,  the Board of  Directors  of the Company has  determined  that the
Optionee  is to be  granted  under the  Company's  1998 Stock  Option  Plan (the
"Plan"),  on the terms and conditions set forth herein, an option (the "Option")
to purchase a specified  number of shares of the common  stock,  par value $0.10

     1. Grant of Option: Number of Shares and Option Price. The Option is for up
to ______  shares of Common Stock (the "Option  Shares") at a price of $x.xx per
share (the "Option  Price").  The Option is granted  pursuant to the Plan and is
subject to the terms and conditions  thereof,  which are incorporated  herein by
this  reference.  To the extent any provision in this Agreement is  inconsistent
with the Plan, the provisions of the Plan shall govern.  The Participant  hereby
acknowledges receipt of, or access to, a copy of the Plan.

     2. Period of Option and Conditions of Exercise.

     (a) The  Option  shall be  considered  granted as of the date  hereof  (the
"Option  Date").  The Option shall expire on Month,  Day, 200X (the  "Expiration
Date").  Upon the  Expiration  Date, the Optionee shall no longer be entitled to
exercise the Option.

     (b) The  Option  may be  exercised  with  respect  to the  number of Option
Shares,  at the times and under the  conditions,  if any, set forth on Exhibit A
hereto.  Once the  Option  is  exercisable  with  respect  to a number of Option
Shares,  the Optionee may exercise the Option at any time from time to time with
respect to all or part of those Option Shares. If requested by the Company,  the
Optionee  shall  deliver this  Agreement to the  Secretary of the Company at the
time of exercise of the Option so that a notation may be made in this  Agreement
as to such exercise.  After such notation has been made,  this  Agreement  shall
then be returned to the Optionee.

     (c) To exercise the Option,  the Participant  must deliver to the Secretary
of the Company at its corporate  headquarters the Notice of Exercise attached as
Exhibit B to this  Agreement  together  with payment of the  aggregate  exercise
price in the manner permitted by the Plan.

     (d) The  Optionee  shall not be deemed to be a holder of any Option  Shares
following  the  exercise of the Option  until the full  exercise  price for such
shares has been paid and a stock  certificate  has been issued and delivered for
such shares.

     3.  Adjustment  in Number of Shares.  The number of Option  Shares shall be
subject to adjustment for stock dividends,  stock splits,  or similar  corporate
change  involving  the Common Stock to the extent set forth in Section 12 of the
Plan.

     4. Termination of Employment.

     (a) In the event of the  termination of the Optionee's  employment with the
Company,  other than a termination that is either (i) for Cause,  (ii) voluntary
on the part of the Optionee and without written consent of the Company, or (iii)
for reasons of death or disability, the Optionee may exercise this Option at any
time within three months after such  termination  to the extent of the number of
shares which were exercisable hereunder at the date of such termination.

     (b) In the event of a  termination  of the  Optionee's  employment  that is
either (i) for Cause or (ii)  voluntary  on the part of the Optionee and without
written  consent of the  Company,  this  Option,  to the  extent not  previously
exercised,  shall  terminate  immediately  and shall not thereafter be or become
exercisable.  For  purposes  of  the  Agreement,  "Cause"  shall  mean  that  or
destruction  of property of the Company or a  subsidiary,  refusal or continuing
inability to perform reasonably  assigned duties,  disregard of Company rules or
policies,  conduct  evidencing willful or reckless disregard of the interests of
the  Company,  or the breach of a material  provision  of this  Agreement.  Such
determination  shall be made by the  Committee and shall be final and binding on
all  parties  hereto.

     5. Disabled Optionee.  In the event of termination of employment because of
the  Optionee's  mental or physical  disability  determined by a medical  doctor
satisfactory   to  the   Company,   the   Optionee   (or  his  or  her  personal
representative) may exercise this Option,  within a period ending on the earlier
of (a) the last day of the one year period following the Optionee's  termination
or (b) the expiration date of this Option, to the extent of the number of shares
which were exercisable hereunder at the date of such termination.

     6. Death of Optionee.  In the event of a termination of employment  because
of the Optionee's  death, the Optionee's  administrators,  executors or personal
representatives,  may exercise this Option at any time within a period ending on
the earlier of (a) the last day of the one year period  following the Optionee's
death or (b) the expiration date of this Option,  to the extent of the number of
shares that were exercisable hereunder at the date of termination.

     7.  Ownership   Change.   In  the  event  of  any  merger,   consolidation,
reorganization,  division  or other  corporate  transaction  in which the common
stock of the Company is  converted  into  another  security or into the right to
receive  securities  or  property  of the  Company  or of any other  entity  (an
"Ownership   Change"),   the  Company  shall  provide  for  the   assumption  or
substitution of comparable stock options in place of the Option.

     8. Option Not  Transferable.  The Option is not transferable  other than by
will or under the laws of descent and  distribution.  During the lifetime of the
Optionee, the Option may be exercised only by the Optionee.

     9. Investment Representations.

the  Optionee  otherwise,  the  Option  and the Option  Shares  obtainable  upon

1933, as amended (the  "Securities  Act"), or under  applicable state securities
laws.

     (b) The  Optionee  acknowledges  that,  prior to the issuance of the Option
Shares, the Company may delay the delivery of certificates for the Option Shares
for such time as the Company deems  necessary or desirable to enable the Company
to comply with (i) the  requirements  of the  Securities  Act or the  Securities
Exchange Act or 1934, as amended,  or any rules or regulations of the Securities
and Exchange Commission or any stock exchange  promulgated  thereunder;  or (ii)
the requirements of applicable state laws relating to authorization, issuance or
sale of such  securities.  The Optionee  shall provide such  information  as the
Company deems necessary or desirable to secure such compliance.

     10.  Legends.  The share  certificates  evidencing  the  Option  Shares may
contain  such  legends as may be  required  in  keeping  with  applicable  state
corporation and securities laws.
