Item 5. Other Events

     The Company is filing this Current Report on Form 8-K for the purpose of
updating previously filed information in its Form 8-K Reports dated September
18 and September 19, 2002, including a statement of the Company's current
analysis of its potential financial exposure, regarding the civil suit filed in
May 1998 in the Grays Harbor County, Washington State Superior trial court and
related actions against the Company's Behr Process Corporation subsidiary.

     This Washington case involves four exterior wood coating products,
representing a relatively small part of Behr's total sales, brought on behalf
of purchasers of these products in nineteen counties in western Washington
State, an area with a particularly humid climate. The plaintiffs allege, among
other things, that after applying these products to their homes and ancillary
structures such as fences and decks, the wood surfaces suffered excessive
mildew. Behr denies the allegations. In January, 1999 the trial court certified
the case as a class action, including all purchasers of the products who reside
in the nineteen counties.

     As previously disclosed, in May 2000 the trial court entered a default
against Behr as a sanction for Behr's failure to produce certain documents in
discovery. The default prevented Behr from presenting evidence to defend itself
with respect to either liability or damages. Thereafter, the jury returned a
verdict awarding damages to the named plaintiffs. The damages awarded in
respect of the homes of the eight homeowner plaintiff claims (excluding one
award to the owners of a vacation resort) ranged individually from $14,500 to
$38,000. The awards were calculated using a formula based on the product used,
the type and square footage of wood surface the product was applied to and
certain other allowances. The formula would result in lesser awards for product
applied to ancillary structures such as fences and decks. Under the verdict,
the same formula will be used for calculating awards on claims that may be
submitted by the subject purchasers of these products. In July 2000, the court
awarded additional damages of $10,000 per claim to the eight homeowner claims,
under the Washington Consumer Protection Act. This increased the total damages
awarded on the homeowner claims to approximately $263,000. The court denied the
plaintiffs' request for an award of additional damages under the Consumer
Protection Act on claims that may be submitted by unnamed class members on the
basis that it lacked statutory authority to award such additional damages. In
addition, the court granted the plaintiffs' motion for attorneys' fees.

     Behr appealed the trial court judgment to the Court of Appeals of
Washington. On September 13, 2002, the Court of Appeals issued its opinion,
ruling in favor of the plaintiffs on substantially all issues, including the
authority of the trial court to award additional damages under the Washington
Consumer Protection Act (up to a maximum of $10,000 to each class member). Behr
intends to petition the Washington State Supreme Court for discretionary review
of the decision of the Court of Appeals. Although Behr believes that rulings by
the trial court constitute reversible error and that there are valid defenses
to the lawsuit, there can be no assurance that the Supreme Court will accept
the appeal or that it will reverse the judgment of the trial court. Behr has
filed with the Court of Appeals of Washington a motion for reconsideration of
that aspect of the appellate court's decision regarding additional damages under
the Washington Consumer Protection Act prior to seeking an appeal of the entire
decision to the Washington State Supreme Court.

     After publication of the trial court's 1999 order certifying the case as a
class action, plaintiffs' counsel stated that they have been contacted by more
than 2,000 persons regarding the case. It is uncertain whether the persons who
have already contacted plaintiffs' counsel have claims they intend

to submit in the class action, whether they will successfully complete the
claims documentation and process, or the extent to which any such claims relate
to homes or ancillary structures. Unless the decision of the Washington trial
court is reversed on appeal, the claim notification process will begin.
Following such notice, persons certifying that they purchased and applied the
relevant products on property that they own and that they experienced mildew on
the property will be entitled to damages according to the formula established
by the trial court as discussed above. The Company anticipates that the number
of claims may then increase significantly over the number of persons who have
already contacted plaintiffs' counsel.

     Although Behr believes that the subject products have been purchased by
thousands of consumers in western Washington, consumer complaints in the past
have been relatively small compared to the total volume of products sold.
Virtually all of the products were sold through independent hardware, building
products and home improvement retailers. Behr generally does not know the
identity of its end customers or the mix of structures on which customers apply
Behr's products.

     Behr and the Company continue vigorously to defend themselves against any
liability and all damages in the other similar class actions previously
reported. The judgment of the Washington trial court described above could
adversely affect certain aspects of the Company's and Behr's defenses in such
other actions. In view of the fact that the Washington trial court judgment was
the result of a default entered as a discovery sanction, the Company and Behr
continue to believe that they have valid defenses in these other actions. All
of the liability claims in these other class actions and in the Washington
State action relate solely to alleged property damages and not to any health

     In light of the above circumstances, unless the decision of the
Washington trial court is reversed on appeal, the Company has determined that
it is probable that a loss has been incurred with respect to the Washington
class action. Based on the Company's analysis of its exposure since the
September 13 decision of the appellate court and the advice of its outside
counsel experienced in other class action lawsuits, the Company's current best
judgment is that its ultimate liability in this action and all of the related
class actions in Washington and other States, including related fees and
expenses, should not materially exceed $200 million pre-tax in the aggregate,
less any possible recoveries from Behr's insurers or from Behr's pending
malpractice claims against the attorneys who defended Behr in the Washington
trial court and who were retained by Behr's insurers prior to the acquisition
of Behr by the Company. The Company cannot assure that the ultimate liability
will not be higher than this estimate and the Company is continuing to refine
its analysis in order to determine an appropriate charge which may be taken
against its third quarter earnings.

     Two of Behr's liability insurers continue to participate in Behr's defense
of the class actions subject to a reservation of rights. One insurer has filed
a declaratory judgment action in the Orange County, California Superior Court
seeking a declaration that the claims asserted in the class action complaints
are not covered by Behr's insurance policies. The other insurer was named as a
defendant in the suit and has filed cross-claims against Behr seeking a similar
declaration. Behr itself has brought an action in the United States Court for
the Western District of Washington against its insurers for acting in bad faith
in their failure to provide Behr an appropriate defense and against the lawyers
retained by these insurers for malpractice in defending Behr in the Washington
State trial court. This action was stayed in June 2001 pending the outcome of
Behr's appeal of the trial court decision.


     Pursuant to the requirements of the Securities Exchange Act of 1934, the
registrant has duly caused this report to be signed on its behalf by the
undersigned thereunto duly authorized.
