SUMMARY OF PRINCIPAL EVENTS

JH calls BP to schedule meeting. Purpose of meeting is not disclosed by JH

JH makes unsolicited proposal to acquire Engelhard. The two CEOs agree to discuss the proposal
the following week

Engelhard retains Merrill Lynch & Co. as its financial advisor and Cahill Gordon & Reindel LLP as
its legal counsel

BP advises JH that a Board meeting is scheduled for December 29 at which the BASF offer will be
discussed

Engelhard Board meeting held.  Response options are discussed.  Board determines it will be
prepared to explore a sale if price is preemptive; $37 per share deemed not preemptive

BP communicates Engelhard Board position to JH

JH indicates to BP he had additional conversations with his board on value and concluded other
competing buyers unlikely, and on this basis $37 per share is a fair price

JH then indicates BASF would increase price to $38 per share if Engelhard holds a due diligence
meeting and information provided supports such a price increase

JH indicates to BP that BASF has not factored in value for potential synergies in arriving at its price

Engelhard Board holds telephonic meeting and reviews JH’s position and concludes $38 per share
is not compelling enough to warrant due diligence and the provision of non-public information

BASF announces it intends to make a hostile offer to acquire Engelhard at $37 per share

BASF files a Tender Offer Statement (the “BASF Offer”) with the SEC communicating its proposed
strategy to acquire Engelhard

Engelhard Board determines the BASF Offer is inadequate and not in the best interests of
Engelhard stockholders

The Board is working to identify and explore alternatives to seek to maximize stockholder value
above the BASF Offer

BOARD RESPONSE TO THE BASF OFFER
THE REASONS FOR THE REJECTION

1)

The Offer does not reflect the stand-alone value of Engelhard

2)

The Offer is opportunistic

3)

The Offer does not reflect sharing of significant potential synergy value of a
combination

4)

The Offer represents a low control premium versus precedent transactions

5)

The Offer values Engelhard at a price below recent trading levels

6)

The exploration of alternatives to maximize value could deliver higher value
than the Offer

7)

The Offer is financially inadequate

3

OFFER DOES NOT FULLY REFLECT STAND-ALONE VALUE OF
ENGELHARD

The Board believes the Offer does not fully reflect the value of the Company’s
businesses, including its strong market positions and future growth prospects

The Board believes the Company has positioned itself to take advantage of
attractive growth opportunities which include:

The Board believes these growth opportunities have not been fully factored into
the long-term EPS growth expectations

OFFER DOES NOT REFLECT SHARING OF SIGNIFICANT
POTENTIAL SYNERGY VALUE

BASF indicated privately that it did not
factor synergies into its price due to
uncertainties in achieving synergies in M&A
situations ⁽²⁾

BASF stated publicly it only sees “modest
synergies”

The Board believes the synergy
opportunity available to BASF is significant
based on management estimates and a
review of precedent transactions

EXPLORATION OF ALTERNATIVES TO MAXIMIZE VALUE COULD
DELIVER HIGHER VALUE THAN OFFER

Your Board is focused on aggressively exploring strategic alternatives to
maximize stockholder value

This strategy may include a sale of the entire company

The Board has retained Merrill Lynch & Co. to assist in the review of these
alternatives

The Board believes that alternatives to the Offer could provide stockholders
with greater value

The Board believes that tendering into
the Offer before the Board and its advisors have had
the opportunity to fully explore alternatives could
interfere with the ability of the Board to effect a
financially superior alternative

CONCLUSION

After careful consideration, including a thorough review of the BASF Offer with
the Company’s legal and financial advisors, the Board unanimously determined
that the BASF Offer is inadequate and not in the best interests of Engelhard
stockholders (other than BASF and its affiliates)

Engelhard’s business plan, fueled by several different value opportunities, is
expected to generate earnings growth and return on capital in the mid-teens
over the next several years

This growth opportunity is something the Wall Street community has only
begun to appreciate

The BASF Offer, from a variety of value metrics, undervalues the upside in the
Company share price

Tendering into the Offer before the Board and its advisors have had the
opportunity to fully explore alternatives could interfere with the ability of the
Board to effect a financially superior alternative

KEY ASSUMPTIONS

Environmental Technologies

Light Duty Vehicles

•Light duty vehicle builds will grow globally at 2% over the plan period, from 62 million vehicles in 2005 to 68 million by 2010, driven primarily by increasing living standards in
       emerging markets.

•N. America with strictest regulation and largest engines averages almost three catalysts per vehicle.  Europe, with increasing penetration rates of catalyzed soot filters (CSF) will
       increase to slightly over two catalysts per vehicle.  Tightening regulatory standards in developing countries will bring the average in these regions up to one catalyst per vehicle.

•Increasingly strict regulatory standards and fluctuating precious metal pricing will require more advanced technology with related value pricing.

•Net effect of the above is that the global market for light duty emission control catalysts will grow at a 5% CAGR, from $1.5B in 2005 to $1.9B by 2010.  Of the $1.9B in 2010,
       $1.4B relates to gasoline with the remaining $0.5B relating to light-duty diesel, primarily in Europe.

•Gasoline:

1.Global segment will grow from 103M catalysts in 2005 to 115M by 2010, a 2.2% CAGR, with an average catalyst manufacturing charge of $12/catalyst.

2.N. America and Europe will show minimal growth with Japan and Korea flat.  Most of the growth will come from emerging markets, led by China.

3.Stricter regulations will be adopted in the emerging markets over the plan period.  China and India will begin Euro 3 this year and Euro 4 by 2008-10.  Brazil will adopt a US Tier
      2 program in 2009.  Russia will begin to implement Euro 2 this year and Euro 3 by 2008.

•Light-duty Diesel:

1.Europe, which accounts for 75% of the market, will grow from 9.4M vehicles in 2005 to almost 12M by 2010, a 5% CAGR.  A large percentage of the remaining 25% is
      produced in Japan and Korea for export into Europe.

2.The biggest driver for this growth is the diesel penetration rate growing from 46% this year to 50% by 2010.

3.The catalyst market for light-duty diesels in Europe is currently forecasted to be almost $400M by the end of 2010.  The largest growth opportunity is the accelerated adoption
      rate of CSF’s.

4.Euro 4, which began phasing in 2004 (2005 new platforms) has not been filter (CSF) forcing.  However, several European countries became aware that ambient air quality
      standards were being exceeded in urban areas, primarily due to particulate matter.  Driving restrictions on unfiltered vehicles were discussed as a possible solution which
      prompted OEM’s to “voluntarily” install filters.

5.Awareness of particulate matter has forced the EU to accelerate the adoption of Euro 5 for light-duty diesel (now projected for 2009).  Euro 5 reduces particulate emissions by
      80% vs. Euro 4 and will be filter forcing for a majority of diesel vehicles.

6.Grow EC’s market share in Europe from 24% to 35% by 2008.
