ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

     A. On April 25, 2005, the shareholders of The Lubrizol Corporation
     ("Lubrizol") approved the adoption of The Lubrizol Corporation 2005 Stock
     Incentive Plan. The Lubrizol Corporation 2005 Stock Incentive Plan allows
     the grants of incentive and nonstatutory stock options, as well as stock
     appreciation rights and restricted and nonrestricted stock or stock unit
     awards. Any employee of The Lubrizol Corporation or its subsidiaries may be
     selected to participate in the plan. In addition, on the day of each Annual
     Meeting of Shareholders, outside directors are granted $60,000 worth of
     restricted stock units. The restriction period is one year at which time
     shares equal to the number of stock units will be issued. The maximum
     number of shares that may be granted under this plan is 4,000,000 shares,
     of which no more than 2,000,000 shares may be settled as full-value awards.
     This plan was approved by shareholders on April 25, 2005.

     The Lubrizol Corporation 2005 Stock Incentive Plan was filed as Exhibit
     10.1 to The Lubrizol Corporation Form 8-K dated April 25, 2005, and
     included the form of Performance Share Award document.

     On December 12, 2005, the Organization and Compensation Committee of the
     Board of Directors of The Lubrizol Corporation approved long-term
     performance pay awards under the 2005 Stock Incentive Plan for the
     2006-2008 performance period and established the long-term incentive pay
     award three-year performance goal for the 2006-2008 performance period. The
     award is based on three-year operating earnings per share performance goal.
     Participants in the long-term incentive pay award for the 2006-2008
     performance period are the officers of The Lubrizol Corporation and other
     key employees as approved by the Organization and Compensation Committee.
     Payment of the awards earned pursuant to the long-term incentive pay award
     for the 2006-2008 performance period will be paid as Lubrizol common shares
     pursuant to a performance share award under The Lubrizol Corporation 2005
     Stock Incentive Plan.

     We are amending the form of Performance Share Award document to include the
     approved performance measure for the 2006-2008 performance period. The
     amended form of Performance Share Award is attached hereto as Exhibit 10.1.

     B. On December 12, 2005, the Organization and Compensation Committee of the
     Board of Directors of The Lubrizol Corporation approved the annual
     incentive pay plan awards under The Lubrizol Corporation Annual Incentive
     Pay Plan for the 2006 performance period and established the performance
     goals for the 2006 performance period. Participants in the long-term
     incentive pay award for the 2006 performance period are the officers of The
     Lubrizol Corporation and other key employees as approved by the
     Organization and Compensation Committee.

     For corporate officers, the 2006 performance measures for awards under The
     Lubrizol Corporation Annual Incentive Plan are EPS, Accelerate Growth,
     Capital Management, Close Divestitures, and Strengthen the Structure and
     Culture. For officers who are business segment leaders, the 2006
     performance measures are based 25 percent on the corporate measures
     described above and 75 percent on business segment measures of EBITDA,
     Accelerate Growth and Capital Management.

     The Lubrizol Corporation Annual Incentive Plan was filed as Exhibit
     (10)(bb) to The Lubrizol Corporation Form 8-K dated December 13, 2004, and
     included the form of Annual Incentive Award Letter. We are amending the
     original filing to include the approved 2006 performance measures for
     awards under The Lubrizol Corporation Annual Incentive Plan with respect to
     corporate officers and business segment leaders.

     The form of Annual Incentive Plan Award Letter with the approved
     performance measures is attached hereto as Exhibit 10.2.



     C. On December 12, 2005, the Board of Directors of The Lubrizol Corporation
     approved the amendment and restatement of The Lubrizol Corporation 2005
     Excess Defined Contribution Plan. This plan provides for profit sharing
     benefits in excess of what is allowed under The Lubrizol Corporation
     Employees' Profit Sharing and Savings Plan, a qualified plan under Section
     401(a) of the Internal Revenue Code, due to the operation of Sections
     401(a)(17) and 415 of the Internal Revenue Code, or as a result of
     deferrals under The Lubrizol Corporation Senior Management Deferred
     Compensation Plan (formerly known as the 2005 Deferred Compensation Plan
     for Officers) or The Lubrizol Corporation 2005 Executive Council Deferred
     Compensation Plan. The investment return for the contributions made under
     the plan are the same as the participant selected investment funds under
     the qualified plan. Benefits are paid in a lump sum cash payment the later
     of six months after separation from service or 30 days after the beginning
     of the year that occurs after the year in which the separation from service
     occurs. As an alternative, a participant can elect at least 12 months in
     advance to have payments made in a lump sum or up to 10 annual
     installments, the payment of which will be made or begin five years after
     the original date of distribution. This plan is unfunded.

     D. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation 2005 Excess Defined Benefit Plan.
     This plan provides for pension benefits in excess of what is allowed under
     The Lubrizol Corporation Pension Plan, a qualified plan under Section
     401(a) of the Internal Revenue Code, due to the operation of Sections
     401(a)(17) and 415 of the Internal Revenue Code, or as a result of
     deferrals under The Lubrizol Corporation Senior Management Deferred
     Compensation Plan (formerly known as the 2005 Deferred Compensation Plan
     for Officers) or The Lubrizol Corporation 2005 Executive Council Deferred
     Compensation Plan. Benefits are paid in a lump sum cash payment the later
     of six months after separation from service or 30 days after the beginning
     of the year that occurs after the year in which the separation from service
     occurs. As an alternative, a participant can elect at least 12 months in
     advance to have payments made in a lump sum cash payment, a life annuity
     payable for at least 10 years, or a 50% or 100% joint and survivor annuity,
     the payment of which will be made or begin five years after the original
     date of distribution. This plan is unfunded.

     E. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation 2005 Officers' Supplemental
     Retirement Plan. This plan provides for benefits to officers selected by
     the Organization and Compensation Committee of the Board of Directors based
     on an average of the highest three years consecutive years of pay during
     the last 10 years. The plan limits years of service to 30 and computes
     benefits on the basis of a 10-year certain and life annuity. Benefits are
     reduced for Social Security and payments made under other Lubrizol benefit
     plans. Benefits are paid in a lump sum cash payment the later of six months
     after separation from service or 30 days after the beginning of the year
     that occurs after the year in which the separation from service occurs. As
     an alternative, a participant can elect at least 12 months in advance to
     have payments made in a lump sum cash payment, a life annuity payable for
     at least 10 years, a 50% or 100% joint and survivor annuity, or annual
     installments of up to 10 payments, the payment of which will be made or
     begin five years after the original date of distribution. This plan is
     unfunded.

     F. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of the Supplemental Retirement Plan for Donald W. Bogus. This
     plan provides for the annual grant of 500 share units until Mr. Bogus'
     separation from service. The plan is credited with additional share units
     for quarterly dividends paid on Lubrizol


                                        3



     shares. Distribution of the shares units will be made to Mr. Bogus in a
     lump sum six months after his separation from service. Mr. Bogus may elect
     to receive the balance in cash or common shares. For units credited after
     January 1, 2004, the distribution will be made in cash. This plan is
     unfunded.

     G. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation 2005 Executive Council Deferred
     Compensation Plan. The plan allows eligible executive officers of The
     Lubrizol Corporation to defer any amount of their variable pay under the
     annual incentive pay plan. Deferred amounts are converted into share units
     based on the current market price of Lubrizol's shares. Lubrizol matches 25
     percent of the amount deferred. Additional share units are credited for
     quarterly dividends paid on Lubrizol shares. At the end of the deferral
     period, which is at least three years, Lubrizol shares are issued equal to
     the number of share units in the participant's account. Units attributable
     to match are paid in cash. This plan is unfunded.

     H. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation Senior Management Deferred
     Compensation Plan (formerly known as the 2005 Deferred Compensation Plan
     for Officers). The plan allows officers and other participants selected by
     the Organization and Compensation Committee of the Board of Directors of
     The Lubrizol Corporation to defer up to 90 percent of their total annual
     pay and long-term incentive pay, and have these amounts credited to various
     cash investment accounts and/or a share unit account. The investment
     returns of the cash investment accounts equal the performance of the
     investment portfolios designated by the Organization and Compensation
     Committee of The Lubrizol Corporation. The number of share units credited
     to the share unit account is based on the price of Lubrizol shares on the
     day the shares units are credited to the account and includes additional
     share units credited for quarterly dividends paid on Lubrizol shares. At
     the end of the deferral period, the deferrals and earnings are distributed
     to the participant. Cash is distributed from the cash account and Lubrizol
     shares are issued equal to the number of share units in the participant's
     share unit account. This plan is unfunded.

     I. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation 2005 Deferred Compensation Plan for
     Directors. This plan allows outside directors of The Lubrizol Corporation
     to defer all or any portion of their annual compensation and annual
     restricted share grants and have these amounts credited to various cash
     investment accounts and/or a share unit account. The investment returns of
     the cash investment accounts equal the performance of the investment
     portfolios designated by the Organization and Compensation Committee of The
     Lubrizol Corporation. The number of share units credited to the share unit
     account is based on the price of Lubrizol shares on the day the shares
     units are credited to the account and includes additional share units
     credited for quarterly dividends paid on Lubrizol shares. At the end of the
     deferral period, the deferrals and earnings are distributed to the
     participant. Cash is distributed from the cash account and Lubrizol shares
     are issued equal to the number of share units in the participant's share
     unit account. This plan is unfunded.

     J. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation Annual Incentive Pay Plan. This
     plan provides for annual variable cash compensation to individuals selected
     by the Organization and Compensation Committee of the Board of Directors.
     This Committee determines a percentage of annual net income to establish
     the amount available for payment under this plan based objective and/or
     subjective performance measures pre-determined by the


                                        4



     Committee for the year. The Committee approves payments, if any, after the
     end of the performance year. Payments are made within 2 1/2 months after
     the end of the performance year.

     K. On December 12, 2005, the Board of Directors approved the amendment and
     restatement of The Lubrizol Corporation Executive Death Benefit Plan.
     Participants in this plan are selected by the Organization and Compensation
     Committee of the Board of Directors. This plan provides a benefit to the
     participant's designated beneficiary following the participant's death. The
     death benefit is a cash payment equal to 250% of the participant's fixed
     salary for a designated year, reducing to 150% for death at or after age 70
     and 100% for death at or after age 75.
