May 10, 2006 Via Facsimile ((212) 269-5420) and U.S. Mail Kenneth W. Orce, Esq. Cahill Gordon & Reindel LLP 80 Pine Street New York, NY 10005 Re:	Engelhard Corporation 	Schedule TO 	Filed May 5, 2006 	File No. 005-37173 	Revised Preliminary Proxy Statement 	Filed May 8, 2006 		File No. 001-08142 Dear Mr. Orce: We have the following comments on the above-referenced filings. Schedule TO-I 1. Please provide the information required by Item 1006(c) of Regulation M-A. Offer to Purchase 2. Please tell us why you have not filed the relevant portions of this offer document as soliciting materials in connection with your proxy solicitation. Cover page 3. Please revise the language in the first paragraph of this cover page that states that you will return tendered and unpurchased securities "as promptly as practicable" after the expiration of the offer to state that you will return such securities "promptly," as required by Rule 13e-4(f)(5). Please make a similar revision (both with respect to a return of securities and to the payment for tendered securities) throughout the offer document, in the letter of transmittal and related documents. Procedures for Tendering Shares, page 15 4. We note in your letter of transmittal a reference to securities held under the Dividend Reinvestment Plan. Please revise this section, and the remainder of the offer document as necessary, to disclose the procedures for tendering those securities. Conditions of the Offer, page 21 5. Please note that it is our position that a tender offer subject to a financing condition must remain open for at least five business after the financing condition has been waived or satisfied. Revise the Offer accordingly. Refer to Exchange Act Release No. 34-24296 (April 3, 1987) for guidance. 6. Refer to the last paragraph of this section relating to your failure to exercise any of the rights described in this section. This language suggests that once an offer condition is triggered, you must decide whether or not to waive the condition. Note that when a condition is triggered and you decide to proceed with the offer anyway, we believe that this constitutes a waiver of the triggered condition(s). Depending on the materiality of the waived condition and the number of days remaining in the offer, you may be required to extend the offer and recirculate new disclosure to security holders. You may not, as this language seems to imply, simply fail to assert a triggered offer condition and thus effectively waive it without officially doing so. Please confirm your understanding supplementally. Source and Amount of Funds, page 22 7. Please disclose whether a material adverse change described in the first bullet point on page 23 has occurred between December 31, 2005 and the present time. Also, explain the meaning of the term "ICON." Certain Information Concerning Engelhard, page 23 8. We note you have incorporated by reference the financial information required by Item 1010(a) of Regulation M-A and have provided the summary information required by Item 1010(c). Please provide information required by Item 1010(c)(4) and (5). Interests of Directors and Executive Officers, page 27 9. With respect to your disclosure in the first paragraph of page 29, please tell us why you need to qualify your disclosure "to the best of [your] knowledge" given your disclosure that your disclosure is based on records and information provided to you. Alternatively, please explain or delete the qualifier. Certain Material United States Federal Income Tax Consequences, page 31 10. While you may recommend that security holders consult their tax advisors with respect to their particular tax consequences, you may not "urge" them to do so. Please revise. Revised Preliminary Proxy Statement Summary of the Recapitalization Plan, page 4 11.
