Lubrizol Announces Cash Tender Offer for Its
4.625% Senior Notes due 2009

CLEVELAND, March 23, 2009 — The Lubrizol Corporation (NYSE:LZ) today announces that it has commenced a cash tender offer for any and all of its $381.8 million principal amount of outstanding 4.625% Senior Notes due October 1, 2009 (CUSIP No. 54927 1 AD6). The Offer to Purchase and accompanying Letter of Transmittal, each dated today, set forth the terms of the tender offer. The company expects to purchase the Senior Notes utilizing a portion of the net cash proceeds from the company’s January 2009 issuance of 8.875% Senior Notes due 2019.

The Senior Notes will be purchased at a price of $1,005 per $1,000 in principal amount of such Senior Notes validly tendered and accepted for purchase, plus accrued and unpaid interest to, but not including, the date on which the Senior Notes will be purchased. The tender offer will expire at 5:00 p.m. EDT on March 30, 2009, unless extended. Any such extension will be followed by a public announcement no later than 9:00 a.m. EDT on the first business day after the previously scheduled expiration date. In the event of an extension, previously tendered Senior Notes will be accepted concurrently for purchase and the company will establish another settlement date for subsequently tendered Senior Notes. Tendered Senior Notes may be withdrawn prior to, but not after, the expiration date.

The tender offer is conditioned upon the satisfaction of certain customary conditions described in the Offer to Purchase. Subject to applicable law, the company may, at its sole discretion, waive any condition applicable to the tender offer and may extend the tender offer. The tender offer is not conditioned on a minimum amount of Senior Notes being tendered. Under certain conditions, and as more fully described in the Offer to Purchase, the company may terminate the tender offer before the expiration date.
