enhancing the value of the Company for the benefit of shareholders, and to
enhance the ability of the Company and its Subsidiaries to attract and retain
individuals of exceptional talent upon whom, in large measure, the sustained

Section 3. Administration.

      The Plan is administered by the Committee. Members of the Committee are
appointed by and serve at the pleasure of the Board, and may resign by written
notice filed with the Chairman of the Board or the Secretary of the Company. A
vacancy on the Committee will be filled by the appointment of a successor member
by the Board. Subject to the express provisions of this Plan, the Committee has
conclusive authority to select Employees to be Participants for Awards and
determine the type and number of Awards to be granted, to construe and interpret
the Plan, any Award granted hereunder, and any Award Agreement entered into
hereunder, and to establish, amend, and rescind rules and regulations for the
administration of this Plan and has additional authority as the Board may from
time to time determine to be necessary or desirable. Notwithstanding the
foregoing, the Committee does not have the discretion with respect to Restricted
Stock Awards granted to Outside Directors pursuant to Section 10 as to prevent
any Award granted under this Plan from meeting the requirements for exemption
from Section 16(b) of the Exchange Act, as set forth in Rule 16b-3 thereunder or
any successor rule or statute.

Section 4. Shares Subject to the Plan.

            (a) Subject to adjustment as provided in the Plan, the maximum
      number of shares as to which Awards may be granted under this Plan is
      4,000,000 Shares, of which no more than 2,000,000 Shares can be settled as
      full-value Awards. In addition to the stated maximums described above,
      this Plan provides the Committee with the flexibility to convert the
      Shares reserved solely for Options and the grant of Stock Appreciation
      Rights into "full value" awards (e.g., restricted stock, performance
      shares, etc.). Specifically:

                                       3
<PAGE>

                  (i) For every Option or Stock Appreciation Right granted, the
            number of Shares available for grant shall be reduced by one Share
            for every one Share granted;

                  (ii) For each of the first 2,000,000 Shares granted as Awards
            other than Options or the grant of a Stock Appreciation Right, the
            number of Shares available for grant shall be reduced by one Share
            for every one Share granted;

                  (iii) For any Awards settled as a full-value Award in excess
            of the 2,000,000 Share limit, the number of Shares available for
            grant shall be reduced by three Shares for every one Share granted

            For example, if we issue 2,000,000 Shares as performance shares
            prior to exhausting our pool of shares for Options, the Committee
            has the flexibility to convert a portion of the remaining options
            into other Award types, but it must be consistent with the 3-to-1
            ratio described above.

            The Company believes this provision provides for the maximum equity
      plan design flexibility while continuing to protect the long-term
      interests of shareholders.

            (b) Any Shares issued hereunder may consist, in whole or in part, of
      authorized and unissued Shares or treasury shares. If: (i) any Shares
      subject to any Award granted hereunder are forfeited, (ii) any Award
      otherwise terminates without the issuance of Shares or payment of other
      consideration in lieu of Shares; (iii) Shares are used to pay the exercise
      price of an Option; or (iv) Shares are withheld from issuance to pay
      withholding taxes, the Shares subject to the Award, to the extent of any
      such forfeiture, termination or withholding, will again be available for
      issuance under the Plan.

            (c) The number of Shares which remain available for issuance
      pursuant to this Plan, together with Shares subject to outstanding Awards,
      at the time of any change in the Company's capitalization, including stock
      splits, stock dividends, mergers, reorganizations, consolidations,
      recapitalizations, or other changes in corporate structure will be
      appropriately and proportionately adjusted to reflect such change in
      capitalization.

Section 5. Eligibility.

      Any Employee is eligible to be selected as a Participant.

Section 6. Stock Options.

      Non-Statutory Stock Options and Incentive Stock Options may be granted
hereunder to Participants either separately or in conjunction with other Awards
granted

                                       4
<PAGE>

under the Plan. Any Option granted to a Participant under the Plan will be
evidenced by an Award Agreement in the form as the Committee may from time to
time approve. Any Option will be subject to the following terms and conditions
and to any additional terms and conditions, not inconsistent with the provisions
of the Plan, as the Committee deems desirable.

            (a) Option Price. The purchase price per Share under an Option will
      be fixed by the Committee in its sole discretion; provided that the
      purchase price will not be less than one hundred percent (100%) of the
      Fair Market Value of the Share on the Grant Date of the Option. Payment of
      the Option Price may be made in cash, Shares, or a combination of cash and
      Shares, as provided in the Award Agreement relating thereto.

            (b) Option Period. The term of each Option will be fixed by the
      Committee in its sole discretion; provided that no Incentive Stock Option
      may be exercisable after the expiration of ten years from the Grant Date.

            (c) Exercise of Option. Options may be exercisable to the extent of
      fifty percent (50%) of the Shares subject thereto after one year from the
      Grant Date, seventy-five percent (75%) of such Shares after two years from
      the Grant Date, and one hundred percent (100%) of such Shares after three
      years from the Grant Date, subject to any provisions respecting the
      exercisability of Options that may be contained in an Award Agreement.

            (d) Incentive Stock Options. The aggregate Fair Market Value of the
      Shares with respect to which Incentive Stock Options held by any
      Participant which are exercisable for the first time by such Participant
      during any calendar year under the Plan (and under any other benefit plans
      of the Company, of any parent corporation, or Subsidiary) will not exceed
      $100,000 or, if different, the maximum limitation in effect at the Grant
      Date under Section 422A of the Code, or any successor provision, and any
      regulations promulgated thereunder. The terms of any Incentive Stock
      Option granted hereunder will comply in all respects with the provisions
      of Section 422A of the Code, or any successor provision, and any
      regulations promulgated thereunder.

Section 7. Stock Appreciation Rights.

      Stock Appreciation Rights may be granted hereunder to Participants either
separately or in conjunction with other Awards granted under the Plan and may,
but need not, relate to a specific Option granted under Section 6. The
provisions of Stock Appreciation Rights need not be the same with respect to
each Participant. Any Stock Appreciation Right related to a Non-Statutory Stock
Option may be granted at the same time such Option is granted or at any time
thereafter before exercise or expiration of such Option. Any Stock Appreciation
Right related to an Incentive Stock Option must be granted at the same time such
Option is granted. Any Stock Appreciation Right related to an Option will be
exercisable only to the extent the related Option is exercisable. In the case of
any Stock Appreciation Right related to any Option, the Stock Appreciation Right

                                       5
<PAGE>

or applicable portion thereof terminates and is no longer exercisable upon the
termination or exercise of the related Option. Similarly, upon exercise of a
Stock Appreciation Right as to some or all of the Shares covered by a related
Option, the related Option will be canceled automatically to the extent of the
Stock Appreciation Rights exercised, and such Shares will not thereafter be
eligible for grant under Section 4(a). The Committee may impose any conditions
or restrictions on the exercise of any Stock Appreciation Right as it deems
appropriate.

Section 8. Restricted Stock Awards.

            (a) Issuance. Restricted Stock Awards may be issued hereunder to
      Participants, either separately or in conjunction with other Awards
      granted under the Plan. Each Award under this Section 8 will be evidenced
      by an Award document from the Company which will specify the vesting
      schedule, any rights of acceleration and such other terms and conditions
      as the Board determines, which need not be the same with respect to each
      Participant.

            (b) Registration. Shares issued under this Section 8 will be
      evidenced by issuance of a stock certificate or certificates registered in
      the name of the Participant bearing the following legend and any other
      legend required by, or deemed appropriate under, any federal or state
      securities laws:

            The sale or other transfer of the common shares represented by this
            certificate is subject to certain restrictions set forth in the
            Award document granted to ___________________ (the registered owner)
            by The Lubrizol Corporation dated _______________, under The
            Lubrizol Corporation 2005 Stock Incentive Plan. A copy of the Plan
            and Award document may be obtained from the Secretary of The
            Lubrizol Corporation.

      Unless otherwise provided in the Award document from the Company, the
      certificates will be retained by the Company until the expiration of the
      Restriction Period. Upon the expiration of the Restriction Period, the
      Company will (i) have the legend removed from the certificates for the
      Shares to which a Participant is entitled in accordance with the Award
      document from the Company and (ii) release the Shares to the custody of
      the Participant.

            (c) Forfeiture. Except as otherwise determined by the Committee at
      the Grant Date, upon separation of service of the Participant for any
      reason during the Restriction Period, all Shares still subject to
      restriction will be forfeited by the Participant and retained by the
      Company; provided that in the event of a Participant's retirement,
      permanent disability, death, or in cases of special circumstances, the
      Committee may, in its sole discretion, when it finds that a waiver would
      be in the best interests of the Company, waive in whole or in part any or
      all remaining restrictions with respect to the Participant's Shares. In
      such case, unrestricted Shares will be issued to the Participant at the
      time determined by the Committee.

                                       6
<PAGE>

            (d) Rights as Shareholders. At all times during the Restriction
      Period, Participants will be entitled to full voting rights with respect
      to all Shares awarded under this Section 8 and will be entitled to
      dividends with respect to the Shares.

Section 9. Stock Awards.

      Awards of Shares may be granted hereunder to Participants, either
separately or in conjunction with other Awards granted under the Plan. Subject
to the provisions of the Plan, the Committee has the sole and complete authority
to determine (i) the Employees to whom Awards will be granted, (ii) the time or
times at which the Awards will be granted, (iii) the number of Shares to be
granted pursuant to the Awards, and (iv) all other conditions of the Awards.
Conditions may include issuance of Shares at the time of the Award is granted or
issuance of Shares at a time or times subsequent to the time the Award is
granted, which subsequent times may be specifically established by the Committee
and/or may be determined by reference to the satisfaction of one or more
performance measures specified by the Committee. The provisions of Stock Awards
need not be the same with respect to each Participant.

Section 10. Outside Directors' Restricted Stock Unit Awards.

            On the close of business on the date of each Annual Meeting of
      Shareholders, each Outside Director will automatically be granted a number
      of Restricted Stock Units equal to an amount calculated by dividing
      $60,000 by the Fair Market Value of a Share on the Grant Date, which will
      be subject to the following terms and conditions and to any additional
      terms and conditions, not inconsistent with the provisions of the Plan, as
      are contained in the applicable Award Agreement.

            (a) Vesting. Restricted Stock Unit Awards granted pursuant to this
      Section 10 will vest upon the earliest to occur of the following dates:

                  (i) one year after the Grant Date;

                  (ii) separation from service under a retirement plan or policy
            of the Company;

                  (iii) death while serving as a director; or

                  (iv) Change of Control pursuant to Section 11.

Section 11. Change in Control.

      Notwithstanding the provisions of Sections 6(c) and 10(a), outstanding
Options will become 100% exercisable and any other outstanding Awards hereunder
will become fully vested and without any restrictions upon the occurrence of any
Change in Control (as

                                       7
<PAGE>

hereafter defined) of the Company; except that no Option may be exercised prior
to the end of six months from the Grant Date.

      Notwithstanding the provisions of Section 8 and the applicable Award
Agreement, any outstanding Restricted Stock Awards will become fully vested and
without any restrictions upon the occurrence of any Change in Control of the
Company.

      For all purposes of the Plan, a "Change in Control" will occur if any of
the following events occurs:

            (a) The Company is merged, consolidated or reorganized into or with
      another corporation or other legal person, and immediately after such
      merger, consolidation or reorganization less than a majority of the
      combined voting power of the then-outstanding securities of such
      corporation or person immediately after such transaction are held in the
      aggregate by the holders of Voting Stock of the Company immediately prior
      to such transaction;

            (b) The Company sells all or substantially all of its assets to any
      other corporation or other legal person, and less than a majority of the
      combined voting power of the then-outstanding securities of such
      corporation or person immediately after such sale are held in the
      aggregate by the holders of Voting Stock of the Company immediately prior
      to such sale;

            (c) There is a report filed on Schedule 13D or Schedule 14D-l (or
      any successor schedule, form or report), each as promulgated pursuant to
      the Exchange Act, disclosing that any person (as the term "person" is used
      in Section 13(d)(3) or Section 14(d)(2) of the Exchange Act) has become
      the beneficial owner (as the term "beneficial owner" is defined under Rule
      13(d)(3) or any successor rule or regulation promulgated under the
      Exchange Act) of securities representing 20% or more of the Voting Stock;

            (d) The Company files a report or proxy statement with the
      Securities and Exchange Commission pursuant to the Exchange Act disclosing
      in response to Form 8-K or Schedule 14A (or any successor schedule, form
      or report or item therein) that a change in control of the Company has or
      may have occurred or will or may occur in the future pursuant to any
      then-existing contract or transaction; or

            (e) If during any period of two consecutive years, individuals who
      at the beginning of any such period constitute the Directors of the
      Company cease for any reason to constitute at least a majority thereof,
      provided, however, that for purposes of this Section 11(e), each Director
      who is first elected, or first nominated for election by the Company's
      stockholders, by a vote of at least two thirds of the Directors of the
      Company (or a committee thereof) then still in office who were Directors
      of the Company at the beginning of any such period will be deemed to have
      been a Director of the Company at the beginning of such period.

                                       8
<PAGE>

      Notwithstanding the foregoing provisions of Section 11(c) or 11(d) hereof,
unless otherwise determined in a specific case by majority vote of the Board, a
"Change in Control" will not occur for purposes of the Plan solely because (i)
the Company, (ii) an entity in which the Company directly or indirectly
beneficially owns 50% or more of the voting securities, or (iii) any employee
stock ownership plan or any other employee benefit plan sponsored by the
Company, either files or becomes obligated to file a report or a proxy statement
under or in response to Schedule 13D, Schedule 14D-l, Form 8-K or Schedule 14A
(or any successor schedule, form or report or item therein) under the Exchange
Act, disclosing beneficial ownership by it of shares of Voting Stock, whether in
excess of 20% or otherwise, or because the Company reports that a change in
control of the Company has or may have occurred or will or may occur in the
future by reason of such beneficial ownership.

Section 12. Amendments and Termination.

      The Board may, at any time, amend, alter or terminate the Plan, but no
amendment, alteration, or termination may be made that would impair the rights
of an Outside Director or Participant under an Award previously granted, without
the Outside Director's or Participant's consent, or that without the approval of
the shareholders would:

            (a) except as is provided in Sections 4(b) and 13(c) of the Plan,
      increase the total number of Shares which may be issued under the Plan;

            (b) change the class of employees eligible to participate in the
      Plan; or

            (c) materially increase the benefits accruing to Participants under
      the Plan;

so long as such approval is required by law or regulation; provided that, as
long as required by law or regulation, the provisions of Section 10 hereof may
not be amended or altered more than once every six (6) months, other than to
comport with changes in the Code, the Employee Retirement Income Security Act,
or the rules thereunder.

      The Committee may amend the terms of any Award heretofore granted (except,
with respect to Restricted Stock Awards granted pursuant to Section 10 hereof,
only to the extent not inconsistent with Rule 16b-3 under the Exchange Act or
any successor rule or statute), prospectively or retroactively, but no such
amendment may impair the rights of any Participant or Outside Director without
his consent.

Section 13. General Provisions.

            (a) No Option or other Award may be assignable or transferable by a
      Participant or an Outside Director otherwise than by will or the laws of
      descent and distribution, and Options and Stock Appreciation Rights may be
      exercised during the Participant's lifetime only by the Participant, or,
      if permissible under applicable law, by the guardian or legal
      representative of the Participant.

                                       9
<PAGE>

            (b) The term of each Award will be for a period of months or years
      from its Grant Date as may be determined by the Committee or as set forth
      in the Plan; provided that in no event may the term of any Incentive Stock
      Option or any Stock Appreciation Right related to any Incentive Stock
      Option exceed a period of ten (10) years from the Grant Date.

            (c) In the event of a merger, reorganization, consolidation,
      recapitalization, stock dividend or other change in corporate structure
      such that Shares are changed into or become exchangeable for a larger or
      smaller number of Shares, thereafter the number of Shares subject to
      outstanding Awards granted to Participants and to any Shares subject to
      Awards to be granted to Participants pursuant to this Plan will be
      increased or decreased, as the case may be, in direct proportion to the
      increase or decrease in the number of Shares by reason of such change in
      corporate structure; provided, however, that the number of Shares will
      always be a whole number, and the purchase price per Share of any
      outstanding Options will, in the case of an increase in the number of
      Shares, be proportionately reduced, and, in the case of a decrease in the
      number of Shares, be proportionately increased. The above adjustment will
      also apply to any Shares subject to Restricted Stock Awards granted to
      Outside Directors pursuant to the provisions of Section 10.

            (d) No Employee may have any claim to be granted any Award under the
      Plan and there is no obligation for uniformity of treatment of Employees

            (f) All certificates for Shares delivered under the Plan pursuant to

      any applicable federal or state securities law, and the Committee may
      cause a legend or legends to be put on any such certificates to make

                                OUTSIDE DIRECTOR
                           RESTRICTED STOCK UNIT AWARD

THIS RESTRICTED STOCK UNIT AWARD, dated this ______ day of ______________,
2_____, (the "Grant Date") by The Lubrizol Corporation (the "Company") to
_________________________________, a member of the Board of Directors of the
Company who is not an Director of the Company or a Subsidiary (as defined in the
Plan).

The following terms and provisions apply to this Restricted Stock Unit Award:

1. This Award grants to you, under the provisions of the Company's 2005 Stock
Incentive Plan, as amended (the "Plan"), the number of Stock Units ("Units")
equal to the amount, set forth in Section 2, which is calculated by dividing
$60,000.00 by the Fair Market Value of a Share of Lubrizol common stock, on the
date of the most recent Annual Meeting of Shareholders, subject to the
restrictions, terms and conditions as hereinafter set forth.

2. The aggregate number of Units granted under this Award is ________.

4. (a) The Restriction Period is one year beginning on the Grant Date and ending
on the first anniversary of the Grant Date.

   (b) If you separate from service as a director of the Company for any reason
prior to the end of the Restriction Period, you will forfeit to the Company all
Units for which the Restriction Period has not expired, provided that in cases
of special circumstances, the Committee (as defined in the Plan) may, in its
sole discretion, when it finds that a waiver would be in the best interests of
the Company, determine that the Restriction Period for any or all of the Units
is deemed to have expired and Share certificates will be issued in accordance
with Section 6.

5. Notwithstanding the provisions of Section 4, the Restriction Period will end
upon: (a) your separation from service in accordance with any retirement plan or
policy of the Company then in effect; (b) your death; or (c) the occurrence of
any Change of Control (as defined in the Plan) of the Company.

6. At the end of the Restriction Period, a Share certificate(s) will be issued
to you in an amount equal to the number of Units subject to the Restriction
Period.

7. If there is a merger, reorganization, consolidation, recapitalization, stock
dividend or other change in corporate structure such that Company Common Shares
are changed into or become exchangeable for a larger or smaller number of
Company Common Shares, the number of Units specified in Section 2, above, will
be increased or decreased, as the case may be, in direct proportion to the
increase or decrease in the number of Company Common Shares by reason of the
change in corporate structure; provided, however, that the number of Units will
always be a whole number.

8. The Restriction Period will not expire if the lapse of restrictions would
violate:

   (a    any applicable state securities law;

                                       1
<PAGE>

      (b)   any applicable registration or other requirements under the
            Securities Act of 1933, as amended (the "Securities Act"), the
            Securities Exchange Act of 1934, as amended, or the listing
            requirements of any stock exchange; or

      (c)   any similar legal requirement of any governmental authority
            regulating the issuance of shares by the Company.

In addition, if a Registration Statement with respect to Shares distributable
under this Plan is not in effect or if counsel for the Company deems it
necessary or desirable in order to avoid possible violation of the Securities
Act, the Company may require, as a condition to its issuance and delivery of
certificate(s) for the Shares, the delivery to the Company of a commitment in
writing by you that at the Grant Date and at the time of expiration of the
Restriction Period it is your intention to acquire such Shares for your own
account for investment only and not with a view to, or for resale in connection
with, the distribution thereof other than in a transaction that does not require
registration under the Securities Act (which may, but will not be required to,
be conclusively determined for the purposes of this Agreement based upon written
advice of counsel for the Company or the Director); that you understand the
Shares distributable hereunder may be "restricted securities" as defined in Rule
144 of the Securities and Exchange Commission; and that any resale, transfer or
other disposition of the Shares will be accomplished only in compliance with
Rule 144, the Securities Act, or other or subsequent applicable Rules and
Regulations thereunder. In these circumstances (except as aforesaid), the
Company may place on the certificate(s) an appropriate legend reflecting the
aforesaid commitment and the Company may refuse to permit transfer of the
certificate(s) until it has been furnished evidence satisfactory to it that no
violation of the Securities Act or the Rules and Regulations thereunder would be
involved in such transfer.

9. The Committee has conclusive authority, subject to the express provisions of
the Plan as in effect from time to time and this Award to interpret this Award
and the Plan, and to establish, amend and rescind rules and regulations for the
administration of the Plan. The Committee may correct any defect or supply any
omission or reconcile any inconsistency in this Award in the manner and to the
extent it deems expedient to carry the Plan into effect, and it is the sole and
final judge of such expediency. The Board of Directors of the Company may from
time to time grant to the Committee further powers and authority as the Board
determines to be necessary or desirable. Notwithstanding any other provision of
this Agreement to the contrary, no amendment, construction, establishment,
rescission or correction of the type referenced above which is made or adopted
following a Change in Control, and which amendment, construction, establishment
or correction adversely affects your rights, will be effective without your
express prior written consent.

10. Notwithstanding any other provision of this Award, the Units will be subject
to all of the provisions of the Plan in force from time to time.

                            2005 STOCK INCENTIVE PLAN
                    NONSTATUTORY STOCK OPTION AWARD AGREEMENT

      remained continuously employed by the Company and/or any of its
      subsidiaries for one year after the Grant Date. After one year, you can
      exercise the Option Rights up to 50% of the Shares specified above. After

      your employer (1) you, at any time within the period specified in Section
      6, may exercise the Option Rights and (2) if there is a Change in Control

      retirement age but elect to retire pursuant to "early retirement"
      provisions of any applicable retirement plan or policy of your employer,
      you may exercise the Option Rights and LSARs to the extent you were
      entitled to exercise them immediately prior to your early retirement, or
      if the Organization and Compensation Committee of the Board of Directors
      of Lubrizol ("Committee"), upon the recommendation of the Chief Executive
      Officer of Lubrizol, specifically approves, you may exercise the Option
      Rights and LSARs up to 100% of the Shares.

<PAGE>

      (d) If you separate from service with Lubrizol or any of its subsidiaries
      for any reason other than retirement or death, then you, at any time
      within three months following your separation from service (but within the
      period specified in Section 6), (1) may exercise the Option Rights and/or
      (2) may, in accordance with Section 9, exercise the LSARs, in each case to
      the extent you were entitled to exercise them immediately prior to your
      cessation of employment, or if the Committee, upon the recommendation of
      the Chief Executive Officer, specifically approves, you may exercise the
      Option Rights and LSARs up to 100% of the Shares.

      (e) If you die while employed by Lubrizol or any of its subsidiaries, then
      (1) for 12 months following the date of death, (but within the period
      specified in Section 6), the executor or administrator of your estate or
      the person entitled by will or the applicable laws of descent and
      distribution may exercise the Option Rights and (2) if there is Change in
      Control within seven months after your death, the person entitled by will
      or by the applicable laws of descent and distribution may, in accordance
      with Section 9, exercise the LSARs, in each case up to of 100% of the
      Shares.

      (f) If there is a Change in Control and your employment with the Company
      or any of its subsidiaries terminates either (1) by your employer other
      than for Cause (as defined below), or (2) by you for Good Reason (as
      defined below) then, notwithstanding anything in this award to the
      contrary, you, at any time within seven months following your termination
      (but within the period specified in Section 6), (A) may exercise the
      Option Rights and/or (B) may, in accordance with Section 9, exercise the
      LSARs, in each case up to 100% of the Shares. The term "Cause" means that,
      prior to your termination of the employment you committed: (I) an
      intentional act of fraud, embezzlement or theft in connection with your
      duties or in the course of your employment; (II) intentional wrongful
      damage to the property of the Company or any of its subsidiaries; or (III)
      intentional wrongful disclosure of secret processes or confidential
      information of the Company or any of its subsidiaries; or (IV) intentional
      wrongful engagement in any Competitive Activity (as defined below); and
      any of these acts was materially harmful to the Company. No act or failure
      to act on your part will be considered "intentional" if it was due
      primarily to an error in judgment or negligence, but will be considered
      "intentional" only if done, or omitted to be done, by you not in good
      faith and without reasonable belief that the action or omission was in the
      best interest of the Company. Notwithstanding the above, you will not be
      considered to have been terminated for "Cause" unless there is delivered
      to you a copy of a resolution duly adopted by the affirmative vote of at
      least three-fourths of the Directors of the Company at a meeting of the
      Directors called and held for that purpose (after reasonable notice to you
      and an opportunity for you, together with your counsel, to be heard before
      the Directors), finding that, in the good faith opinion of the Directors,
      you had committed an act described above in this Section 4(f) and
      specifying the particulars thereof in detail. Termination of employment by
      you will be considered for "Good Reason" if you terminate employment and
      any of the following events has occurred (regardless of whether any other
      reason, other than for Cause, for the termination exists or has occurred,
      including without limitation other employment):

            (i). Failure to elect or reelect or otherwise maintain you in the
            office or in the position, or a substantially equivalent office or
            position, which you held immediately prior to a Change in Control,
            or your removal as a Director of the Company (or any successor
            thereto) if you were a Director of the Company immediately prior to
            the Change in Control;

                                       2
<PAGE>

            (ii). A significant adverse change in the nature or scope of the
            authorities, powers, functions, responsibilities or duties attached
            to the position you held immediately prior to the Change in Control,
            a reduction in the aggregate of your annual compensation, or the
            termination or denial of your rights to employee benefits in which
            your similarly situated co-workers participate, or a reduction in
            scope or value thereof without your prior written consent, any of
            which is not remedied within ten calendar days after receipt by the
            Company of your written notice of the change, reduction or
            termination, as the case may be;

            (iii). A determination you made in good faith that as a result of a
            Change in Control and a change in circumstances thereafter
            significantly affecting your position, including, a change in the
            scope of the business or other activities for which you were
            responsible immediately prior to a Change in Control, you have been
            rendered substantially unable to carry out, have been substantially
            hindered in the performance of, or have suffered a substantial
            reduction in, any of the authorities, powers, functions,
            responsibilities or duties attached to the position held by you
            immediately prior to the Change in Control, which situation is not
            remedied within ten calendar days after receipt by the Company of
            your written notice of your determination; or

            (iv). The Company relocates its principal executive offices, or
            changes your principal location of work, to any location which is
            more than 50 miles from the location immediately prior to the Change
            of Control or to travel away from your office significantly more
            than was required prior to the Change in Control without, in either
            case, your prior written consent.

      The term "Competitive Activity" means your participation, without the
      written consent of an officer of the Company, in the management of any
      business enterprise if that enterprise engages in substantial and direct
      competition with the Company and the enterprise's sales of any product or
      service competitive with any product or service of the Company amounted to
      25% of such enterprise's net sales for its most recently completed fiscal
      year and if the Company's net sales of said product or service amounted to
      25% of the Company's net sales for its most recently completed fiscal
      year. "Competitive Activity" does not include (i) the mere ownership of
      securities in any such enterprise and exercise of rights appurtenant
      thereto or (ii) participation in management of any such enterprise other
      than in connection with the competitive operations of such enterprise.

      (g) If you, after leaving the employ of the Company, die during one of the
      periods described in Section 4(c), (d) or (f), the executor or
      administrator of your estate, or the person entitled by will or the
      applicable laws of descent and distribution, may exercise the Option
      Rights held by you at the time of your death during the applicable period,
      as follows:

            (i).   If Section 4(c) was in effect, for one (1) year after your
                   death;

            (ii).  If Section 4(d) was in effect, for three (3) months after
                   your death;

            (iii). If Section 4(f) was in effect, for one (1) year after your
                   death;

                                       3
<PAGE>

      provided that, the Option Rights may not be exercised after the period
      specified in Section 6.

5. The Option Rights and LSARs are not transferable other than by will or by the
laws of descent and distribution, and are exercisable during your lifetime only
by you or your guardian or legal representative. In addition, except as
otherwise provided by Sections 4(c), 4(d), 4(e), 4(f), 4(g) and 8, the Option
Rights and/or LSARs can be exercised only if you remain continuously employed by
Lubrizol or any of its subsidiaries from the Grant Date to the date of exercise.

6. Notwithstanding any other provision hereof, the Option Rights expire ten
years after the Grant Date, or earlier as described in Sections 4(c), 4(d),
4(e), 4(f), 4(g) or 8.

7. If there is a merger, reorganization, consolidation, recapitalization, stock
dividend or other change in corporate structure so that Company Common Shares
are changed into or become exchangeable for a larger or smaller number of
Company Common Shares, the number of Shares subject to this award will be
increased or decreased in direct proportion to the increase or decrease in the
number of Company Common Shares by reason of the change in corporate structure;
provided, however, that the purchase price per Share will, in the case of an
increase in the number of Shares, be proportionately reduced, and, in the case
of a decrease in the number of Shares, be proportionately increased. If there is
any other change in the number or kind of outstanding Company Common Shares or
other Company securities, or of any shares of stock or other securities into
which Company Common Shares have been changed or for which they have been
exchanged, then the Committee may make an adjustment in the number or kind of
shares of stock or other securities purchasable hereunder, and in the manner of
purchasing such stock or other securities and the price to be paid, as the
Committee determines is equitably required by the change, and the adjustment
will be effective and binding for all purposes of the Option Rights.

8. If the Company liquidates or dissolves, the Company will give to you at least
thirty (30) days' prior written notice, and you will have the right within the
thirty (30) day period (but within the period specified in Section 6) to
exercise the Option Rights to the extent you otherwise are entitled to exercise
the Option Rights. Any Option Rights which have not been exercised before the
effective date of the liquidation or dissolution will terminate.

9. In accordance with the terms described in this Section 9, the Company grants
to you limited stock appreciation rights ("LSARs") with respect of each of the
Shares to which the Option Rights relate. Upon exercise of the LSARs, (a) you
will be entitled to receive a cash amount equal to the amount by which the Fair
Market Value (as defined below) of a Share exceeds the option price set forth in
Section 3 hereof, multiplied by the number of LSARs exercised, and (b) an equal
number of Option Rights will automatically be canceled. You may exercise a LSAR
only within sixty (60) days (but within the period specified in Section 6) after
you receive written notice from the Company that there has been a Change in
Control. You may exercise the LSARs by delivering to the Company at the office
of its Vice President, Human Resources, a signed written notice, of your
election to exercise in whole or in part the LSARs. The term "Fair Market Value"
means the higher of (1) the highest daily closing price (as reported on the New
York Stock Exchange Composite Transactions) for a Share during the period
beginning on the 60th day prior to the date on which the LSAR is exercised and
(2) the highest gross price paid or to be paid for a Share in any Change in
Control event described in Section 4(b).

                                       4
<PAGE>

10.   (a) You may exercise the Option Rights by delivering to the Company at the
      office of its Vice President, Human Resources, a signed written notice of
      your election to exercise the Option Rights. You must include with the
      notice payment of the full purchase price of the Shares to be purchased,
      except as provided in Section 10(b). You must also pay, within the time
      period specified by the Company, the amount, if any, of the tax to be
      withheld for federal, state or local tax purposes on account of the
      exercise of the Option Rights. You may pay the purchase price and any
      withholding tax in cash (which may include withholding from your next
      salary payment), in Company Common Shares or in any combination of cash
      and Company Common Shares. If you use Company Common Shares to pay the
      purchase price of Shares being purchased: (1) you may do so either by
      actually delivering the share certificates or by attesting as to the
      ownership of the Common Shares; and (2) you must have owned them at least
      for six (6) months.

      (b) You may elect to pay the purchase price upon the exercise of the
      Option Rights by authorizing a third party to sell all the Shares (or a
      sufficient portion of the Shares) acquired upon the exercise of the
      Options Rights and to remit to the Company a sufficient portion of the
      sale proceeds to pay the entire purchase price and any tax withholding
      resulting from the exercise.

      (c) All elections must be made in writing and be submitted to the
      Company's Vice President, Human Resources. All elections by officers are
      irrevocable and are subject to the approval of the Committee.

      (d) The Company will withhold a sufficient number of Shares that will
      provide for the federal, state and/or local income tax at the rates then
      applicable for supplemental wages, unless otherwise requested by you, but
      in no event less than the statutory minimums for tax withholding.

      (e) For purposes of determining the number of Company Common Shares that
      are to be used in payment of the purchase price or to be withheld to
      provide for the tax withholding pursuant to Section 10(a), Company Common
      Shares will be valued at the average of the high and low trading prices on
      the New York Stock Exchange on the date you exercise the Option Rights. If
      the determination of the tax withholding would require the withholding of
      a fractional Share, the Company shall withhold the nearest whole number of
      Shares needed to pay the tax withholding, rounded up, and remit to you in
      cash the amount of the excess after the withholding taxes have been
      satisfied. Upon payment of any tax withholding, as described above, the
      Option Rights are considered to be exercised as of the date the Company
      received your notice of the election to exercise the Option Rights, or, if
      applicable, the date of the sale of Shares as described in Section 10(b).
      Upon the proper exercise of the Option Rights, the Company will issue and
      deliver to you, a certificate or certificates for the Shares purchased.
      You agree that, as a holder of the Option Rights, you have no rights as a
      shareholder with respect to any of the Shares as to which this Option
      applies unless you effectively exercise your Option Rights in accordance
      with the provisions in this Section 10.

11.   Neither the Option Rights nor the LSARs will be exercisable if the
      exercise would violate:

      (a) any applicable state securities law;

                                       5
<PAGE>

      (b) any applicable registration or other requirements under the Securities
      Act of 1933, as amended (the "Securities Act"), the Securities Exchange
      Act of 1934, as amended, or the listing requirements of any stock
      exchange; or

      (c) any similar legal requirement of any governmental authority regulating
      the issuance of shares by the Company.

In addition, if a Registration Statement for Shares under this Plan is not in
effect or if the Company's counsel considers it necessary or desirable in order
to avoid possible violation of the Securities Act, the Company may require the
delivery to the Company of your written commitment that: (1) it is your
intention to acquire the Shares for your own account for investment purposes
only and not with a view to resell the Shares other than in a transaction that
does not require registration under the Securities Act; (2) you understand the
Shares may be "restricted securities" as defined in Rule 144 under the
Securities Act; and (3) that any resale, transfer or other disposition of the
Shares will be accomplished only in compliance with Rule 144 under the
Securities Act. In certain circumstances, the Company may place a legend on the
Shares certificates reflecting the commitment described above, and the Company
may refuse to permit transfer of the Share certificates until the Company has
been furnished with evidence satisfactory to it that the transfer would not
result in a violation of the Securities Act or the Rules and Regulations.

12. Notwithstanding any other provision of this Agreement, if you are terminated
from employment by the Company for Cause (as defined in Section 4(f) above), you
will forfeit all of your vested and non-vested Options granted under this
Agreement that are outstanding on the date of your termination.

13. The Committee has conclusive authority, subject to the express provisions of
the Plan as in effect from time to time and this award, to construe this award
and the Plan, and to establish, amend and rescind rules and regulations for the
administration of the Plan. The Committee may correct any defect or supply any
omission or reconcile any inconsistency in this award in the manner and to the
extent it considers expedient to carry the Plan into effect. The Board of
Directors of the Company may from time to time grant to the Committee further
powers and authority as the Board determines to be necessary or desirable.
Notwithstanding any other provision of this award to the contrary, no amendment,
construction, establishment, rescission or correction of the type referenced
above which is made or adopted following a Change in Control, and which
amendment, construction, establishment or correction adversely affects your
rights, will be effective without your express prior written consent.

14. You must hold any Shares that are distributed to you upon the exercise of
the Option under this Award, at least until you have met your Share ownership
guideline.

15. Notwithstanding any other provision of this award, the Option Rights will be
subject to all of the provisions of the Plan in force from time to time.

      IN WITNESS WHEREOF, the parties hereto have executed this Agreement in
duplicate as of the day and year first above written.

2_____, (the "Grant Date") by The Lubrizol Corporation (the "Company") to
_________________________________ , an employee of the Company and/or a
Subsidiary (as defined in the Plan).

      The following terms and provisions apply to this Performance Share Award:

1. The Company hereby grants to you, under the provisions of Section 9 of the
Company's 2005 Stock Incentive Plan, as amended (the "Plan"), the number of
Company Common Shares, without par value, in accordance with the three-year
performance target chart(s) as shown in Exhibit A attached to this Award. The
Company Common Shares granted hereunder are referred to herein as the "Shares".

2. If there is a Change of Control, as defined under the Plan, prior to the
receipt of Shares under Section 1, above, you will receive a pro-rata number of
Shares upon the Change of Control. The pro-rata number of Shares will be
determined as shown on Exhibit B attached to this Award.

3. If you separate from service due to retirement (either normal or early
retirement) prior to the receipt of Shares pursuant to Section 1, above, you
will receive a pro-rata number of Shares upon the end of the three-year cycle
based on the number of full months which have elapsed since the date of this
Award at the time or your separation from service or death. In no event will the
payment of Shares be made earlier than six months after your retirement.

      If you separate from service due to death prior to the receipt of Shares
pursuant to Section 1, above, your beneficiary will receive a pro-rata number of
Shares upon the end of the three-year cycle based on the number of full months
which have elapsed since the date of this Award at the time or your service or
death. You may at any time specify in writing a beneficiary to receive the
Shares if you die before the receipt of Shares under this Award. If the Company
does not have a beneficiary election on file at the time of your death, the
Shares will be issued to your spouse, or if your spouse is not living at the
time of issuance, your children who are living, or if you have no living
children at the time of issuance, your estate.

      If you separate from service (voluntarily or involuntarily) for any other
reason prior to the receipt of Shares pursuant to Section 1, above, you will
forfeit any Shares under this Award.

4. The Award is not transferable by you during your life.

5. Prior to the issuance of Shares to you, you will not be a shareholder of the
Company and you will have no rights under the Award as a shareholder of the
Company. No dividends or other amount will be allocated or paid to you with
respect to the Award.

6. If there is a stock split, reverse stock split or stock dividend, the number
of Shares specified in Section 1, above will be increased or decreased in direct
proportion to the increase or decrease in the number of Company Shares by reason
of the stock split, reverse stock split or stock dividend.

7. Shares will not be distributed under this Award if the issuance of the Shares
would violate:

      (a)   any applicable state securities law;

      (b)   any applicable registration or other requirements under the
            Securities Act of 1933, as amended (the "Securities Act"), the
            Securities Exchange Act of 1934, as amended, or the listing
            requirements of any stock exchange on which the Company's Shares are
            listed; or

      (c)   any similar legal requirement of any governmental authority
            regulating the issuance of shares by the Company.

Further, if a Registration Statement with respect to the Shares to be issued is
not in effect or if counsel for the Company deems it necessary or desirable in
order to avoid possible violation of the Securities Act, the Company may
require, as a condition to its issuance and delivery of certificates for the
Shares, that you deliver to the Company a statement in writing that you
understand the Shares may be "restricted securities" as defined in Rule 144 of
the Securities and Exchange Commission and that any resale, transfer or other
disposition of the Shares will be accomplished only in compliance with Rule 144,
the Securities Act, or other or subsequent applicable Rules and Regulations
thereunder. Further still, the Company may place on the certificates evidencing
the Shares an appropriate legend under Rule 144.

8.    (a) When the Common Shares are distributable to you pursuant to Section 1,
      above, you may be subject to income and other taxes on the value of the
      Shares on the date of distribution. The Company will withhold a sufficient
      number of Shares that will provide for the federal, state and/or local
      income tax at the rates then applicable for supplemental wages, unless
      otherwise requested by you, but in no event less than the statutory
      minimums for tax withholding.

      (b) For purposes of determining the number of Common Shares that are to be
      withheld to provide for the tax withholding pursuant to Section 8(a),
      Common Shares will be valued at the average of the high and low trading
      prices on the New York Stock Exchange on the date Shares are distributable
      to you. If the determination of the tax withholding requires the
      withholding of a fractional Share, the Company shall withhold the nearest
      whole number of Shares needed to pay the tax withholding, rounded up, and
      remit to you in cash the amount of the excess after the withholding taxes
      have been satisfied.

9. Prior to the distribution of Shares pursuant to Section 1, the Committee has
the right in its sole discretion to reduce the amount of this Award.

10. The Committee has conclusive authority, subject to the express provisions of
the Plan, as in effect from time to time, and this Award, to interpret this
Award and the Plan, and to establish, amend and rescind rules and regulations
for the administration of the Plan. The Committee may correct any defect or
supply any omission or reconcile any inconsistency in this Award in the manner
and to the extent it deems expedient to carry the Plan into effect, and it is
the sole and final judge of such expediency. The Board of Directors of the
Company may from time to time grant to the Committee such further powers and
authority as the Board determines to be necessary or desirable.

                                    EXHIBIT B

Determination of Pro-Rata Common Shares Upon a Change of Control Under Section 2

      Pursuant to the terms of Section 2, the number of pro-rata Common Shares
upon a Change of Control will be determined as follows:

1. No payout if 12 months has not elapsed since the date of this Award.

2. If more than 12 months has elapsed since the date of this Award:

      (a)   Determine the measurement growth rate for each full year that has
            elapsed in the 3-year period as of the date of the Change of
            Control,

      (b)   The 3-year cumulative measurement growth will be imputed as either
            the 1-year measurement growth (if the Change of Controls occurs
            during the second year) or the 2-year cumulative measurement growth
            (if the Change of Control occurs during the third year).

      (c)   Payout is then pro-rated based on number of full months that have
            elapsed since the date of this Award.
