THE PURPOSE OF THIS AMENDMENT NO. 6 TO SCHEDULE 13D IS TO AMEND THE
OWNERSHIP REPORTS OF THE REPORTING PERSONS AND TO AMEND ITEM 4(PURPOSE OF
TRANSACTION), ITEM?6 (CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR
RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER) AND ITEM 7 (MATERIAL
TO BE FILED AS EXHIBITS). THE INFORMATION BELOW SUPPLEMENTS THE INFORMATION
PREVIOUSLY PROVIDED.

Item 4.     Purpose of Transaction

      On July 23, 2010, Immucor, Inc. (the "Issuer") entered into a
Cooperation Agreement (the "Agreement") with ValueAct Capital Master Fund,
L.P., ValueAct SmallCap Master Fund, L.P. and certain of their affiliates
(collectively, the "ValueAct Parties") and G. Mason Morfit, in his individual
capacity.  The ValueAct Parties collectively own in the aggregate 8,913,336
shares, or approximately 12.7% of the outstanding common stock of the Issuer.

      Pursuant to the Agreement, in consideration for certain restrictions
and limitations to be placed on the ValueAct Parties as summarized below, the
Issuer's board of directors (the "Board"), among other things: (i) elected G.
Mason Morfit, a partner at ValueAct Capital, to the Board and (ii) determined
to nominate Mr. Morfit for election to the Board at the Issuer?s 2010 annual
shareholders meeting (the "2010 Annual Meeting").

      In consideration for the foregoing, the ValueAct Parties agreed,
subject to certain exceptions, that until the date immediately after the date
of the Issuer's 2011 annual shareholders meeting, the ValueAct Parties will
not, among other things: (i) acquire any securities of the Issuer if,
immediately after such acquisition, the ValueAct Parties would collectively
own in the aggregate more than 20% of the then outstanding voting securities
of the Issuer, (ii) propose or seek to effect any tender or exchange offer,
merger or other business combination involving the Issuer, or tender any
voting securities of the Issuer into any tender or exchange offer, (iii)
make, or in any way participate in any solicitation of proxies to vote any
voting securities of the Issuer or (iv) sell, transfer or otherwise dispose
of any voting securities of the Issuer to any person who is (or will become
upon consummation of such sale, transfer or other disposition) a beneficial
owner of 10% or more of the outstanding voting securities of the Issuer.

      Mr. Morfit has agreed, upon becoming a member of the Board to (i)
remain "independent" under applicable rules of The Nasdaq Stock Market, (ii)
be qualified to serve as a director under the Georgia Business Corporation
Code and (iii) not serve as a director (or in a similar capacity) with any
company identified by the Issuer as a competitor of the Issuer.  If during
the term of the Agreement, Mr. Morfit dies, resigns, or is disqualified or
removed, or his nomination at the 2010 Annual Meeting is withdrawn, then the
Agreement provides that the ValueAct Parties and the Board will work together
in good faith to fill the resulting vacancy with, or nominate, an employee of
the ValueAct Parties who meets certain conditions described in the Agreement
and is otherwise mutually acceptable to the Issuer and the ValueAct Parties.

      The ValueAct Parties will lose the right to a Board seat if the
ValueAct Parties cease to beneficially own, in the aggregate, at least 5% of
the outstanding voting securities of the Issuer, in which case Mr. Morfit
must offer to resign from the Board.

- -----------------------------------------------------------------------------


      The foregoing description of the Agreement is qualified in its entirety
by reference to the full text of the Agreement, which is attached as Exhibit
10.1 to the Issuer's Current Report on Form 8-K dated July 26, 2010  and

power and voting control over shares owned by ValueAct SmallCap Master Fund,
L.P. (subject to certain emergency/default rights of VA Partners I, LLC

legal or contractual agreements currently in effect that would give the
ValueAct Master Fund Reporting Persons currently exercisable rights to
beneficial ownership of the ValueAct SmallCap Master Fund shares or the
ValueAct SmallCap Master Fund Reporting Persons currently exercisable rights
to?beneficial ownership of the ValueAct Master Fund shares.? The ValueAct
Master Fund Reporting Persons and the ValueAct SmallCap Master Fund Reporting
Persons, however, share common facilities and services, have discussed their
respective ownership of the Issuer's shares in the past, and may discuss,
share ideas and confer with each other on the ownership, disposition and

Reporting Persons disclaim Beneficial Ownership of the Issuer's 1,372,671
shares owned by ValueAct SmallCap Master Fund.  The ValueAct SmallCap Master
Fund Reporting Persons disclaim Beneficial Ownership of the Issuer's
7,540,665 shares owned by ValueAct Master Fund.

Cooperation Agreement is incorporated herein by reference.

       Other than as described elsewhere in this Report and as previously

required to be described hereunder.
