Exhibit (10)(v)

                            THE LUBRIZOL CORPORATION

                  2005 Deferred Compensation Plan For Directors

1. Purpose. The purpose of this 2005 Deferred Compensation Plan For Directors
(the "Plan") is to continue to permit any member of the Board of Directors (the
"Participant") of The Lubrizol Corporation (the "Company"), to defer all or a
portion of the compensation earned as a director in calendar years beginning on
or after January 1, 2005, until after the Participant separates from service as
a director, all as provided in the Plan.

2. Administration. The Plan shall be administered by the Organization and
Compensation Committee of the Board of Directors of the Company (the
"Committee"). The Committee's interpretation and construction of all provisions
of this Plan shall be binding and conclusive. In the event that a Participant is
a member of the Committee, such Participant shall not participate in any
decision of the Committee relating to that Participant's participation in this
Plan.

3. Right to Defer Compensation.

      (a)   Any director of the Company may, at any time prior to January 1 of a
given calendar year, elect to defer under this Plan all, or such portion as the
director may designate, of (i) that director's annual retainer fee, (ii) the
attendance fees for attending directors' meetings or committees thereof and/or
(iii) stock compensation under The Lubrizol Corporation 2005 Stock Incentive
Plan. All compensation deferred shall be deferred on the day that such
compensation would otherwise have been paid to the director.

      (b)   The election described in paragraph (a) shall be made by written
notice delivered to the Vice President, Human Resources, of the Company
specifying (i) the portion of designated compensation to be deferred for such
year, (ii) time of distribution, and (iii) if applicable, the payment option as
provided in Section 6 for distributions upon separation from service.

      (c)   The election under this Section 3 shall take effect on the first day
of the calendar year following the year in which the election is made. A new
election must be made for each calendar year.

                                       1


4. Deferral of Cash Compensation.

      (a)   On the date the cash compensation deferred under the Plan would have
become payable to the Participant in the absence of an election under the Plan
to defer payment thereof, the amount of such deferred compensation shall be
credited to a Stock Deferral Account and/or any of the Cash Deferral Account
investment portfolios designated as available by the Committee from time to
time. All Deferral Accounts shall be established and maintained for each
Participant in the Company's accounting books and records and the Company shall
be under no obligation to purchase any investments designated by the
Participant.

      (b)   Participant's Cash Deferral Accounts shall be credited with any
gains or losses equal to those generated as if the Participant's Cash Deferral
Account balances had been invested in the applicable investment portfolio(s)
selected by the Participant

      (c)   A Participant's deferred cash compensation credited to a
Participant's Stock Deferral Account shall be used to determine the number of
full and fractional units ("Units") representing Company Common Shares
("Shares") which the deferred amount would purchase at the closing price for the
Shares on the New York Stock Exchange ("NYSE") composite transactions reporting
system on the date that the deferred amount is credited pursuant to paragraph
(a) and if Shares were not traded on that date on the NYSE, then such
computation shall be made as of the first preceding day on which Shares were so
traded. The Company shall credit the Participant's Stock Deferral Account with
the number of full and fractional Units so determined. A Participant's Stock
Deferral Account shall be administered in accordance with Section 5(b) through
(e).

      (d)   A Participant may elect pursuant to rules established by the
Committee to transfer a portion or all of the balance of any Deferral Account
established under this Section 4 to any other such Deferral Account.

5. Deferral of Stock Compensation.

      (a)   At the time that Shares are distributable to a Participant, who has
elected to defer the receipt thereof under Section 3, in lieu of Shares being
issued, there shall be credited to a separate Stock Deferral Account for the
Participant, full stock equivalent units ("Units") which shall be established
and maintained on the Company's records. One Unit shall be allocated to the
Stock Deferral Account for each such Share. The balance of a Stock Deferral
Account established under this Section 5(a) pursuant to deferrals under Section
3 may not be transferred to any other Deferral Account.

      (b)   As of each dividend payment date established by the Company for the
payment of cash dividends with respect to its Shares, the Company shall credit
each separate Stock Deferral Account of a Participant with an additional number
of whole and/or fractional Units equal to:

            (i)   the product of (x) the dividend per Share which is payable
                  with respect to such dividend payment date, multiplied by (y)
                  the number of whole and fractional Units credited to the
                  separate Stock Deferral Account of a Participant as of such
                  payment date;

                                   divided by

                                       2


            (ii)  The closing price of a Share on the dividend payment date (or
                  if Shares were not traded on that date, on the next preceding
                  day on which Shares were so traded), as reported on the
                  NYSE-composite tape.

      (c)   At no time prior to actual delivery of Shares pursuant to the Plan,
shall the Company be obligated to purchase or reserve Shares for delivery of a
Participant and the Participant shall not be a shareholder nor have any of the
rights of a shareholder with respect to the Units credited to the Participant's
Stock Deferral Accounts.

      (d)   In the event of any change in the number of outstanding Shares by
reason of any stock dividend, stock split up, recapitalization, merger,
consolidation, exchange of shares or other similar corporate change, the number
of Units in each separate Stock Deferral Account of a Participant shall be
appropriately adjusted to take into account any such event.

6. Payment of Deferred Compensation upon Separation from Service.

      (a)   For any deferral year, the total amount standing as a credit in a
Participant's Cash Deferral Accounts shall, after a separation from service, be
payable to the Participant either in a lump sum or in periodic installments over
such period, not exceeding ten (10) years, as the Participant shall have
selected pursuant to Section 3(b)(iii). Such periodic payments shall begin or
the lump sum payment shall be made, as the case may be, from the Participant's
Cash Deferral Accounts, at such time, not less than six (6) nor more than twelve
(12) months after the Participant's separation from service, as the Participant
shall have selected pursuant to Section 3(b)(ii). Notwithstanding the foregoing,
a Participant may elect not less than twelve (12) months prior to the
Participant's separation from service, to change the form of distribution of the
Participant's Cash Deferral Accounts; provided, however that any such change of
form of distribution shall be invalid if the effect of such change is to
accelerate distribution; provided, further, that if a Participant elects a
change to the form of distribution in accordance with Section 6(a), the
distribution shall occur five (5) years after the date originally selected
pursuant to Section 3(b)(ii)

      (b)   The amount of each installment payable to a Participant shall be
determined by dividing the aggregate balance of such Participant's Cash Deferral
Accounts by the number of periodic installments (including the current
installment) remaining to be paid. Until a Participant's Cash Deferral Accounts
has been completely distributed, the balance thereof remaining, from time to
time, shall be credited with gains and losses on a monthly basis as provided in
Section 4(b).

      (c)   The total number of Units credited to the Participant's Stock
Deferral Accounts shall upon separation from service be payable to the
Participant either in a lump sum or in periodic installments, over such period,
not exceeding ten (10) years, as the Participant shall have selected pursuant to
Section 3(b)(iii). Such periodic payments shall begin or the lump sum payment
shall be made, as the case may be, from the Participant's Stock Deferral
Accounts, at such time, not less than six (6) nor more than twelve (12) months
after the Participant's separation from service, as the Participant shall have
selected pursuant to Section 3(b)ii). Notwithstanding the foregoing, a
Participant may elect not less than twelve (12) months prior to the
Participant's separation from service, to change the form of distribution of the
Participant's Stock

                                       3


Deferral Accounts; provided, however that any such change of form of
distribution shall be invalid if the effect of such change is to accelerate
distribution; provided, further, that if a Participant elects a change to the
form of distribution in accordance with Section 6(a), the distribution shall
occur five (5) years after the date originally selected pursuant to Section
3(b)(ii)

      (d)   The amount of any installment payable from the Stock Deferral
Accounts to a Participant shall be determined by dividing the balance of the
aggregate number of Units in the Participant's Stock Deferral Accounts by the
number of periodic installments (including the current installment) remaining to
be paid and the quotient shall be the number of Shares that are payable. If the
determination of the installment payable from the Participant's Stock Deferral
Accounts results in a fractional Share being payable, the installment payment
shall exclude any such fractional Share payment except that, in the final
installment payment, any such fractional Share shall be paid in cash in an
amount as determined by the Committee. Until the Participant's Stock Deferral
Accounts have been completely distributed, the balance in the Stock Deferral
Accounts shall continue to be credited with the dividend equivalents on such
balances as provided in Section 5(b).

      (e)   In the event a Participant dies prior to receiving payment of the
entire amount in that Participant's Cash Deferral Accounts and/or Stock Deferral
Accounts, as the case may be, the unpaid balance shall be paid to such
beneficiary as the Participant may have designated in writing to the Vice
President, Human Resources, of the Company as the beneficiary to receive any
such post-death distribution under the Plan or, in the absence of such written
designation, to the Participant's legal representative or to the beneficiary
designated in the Participant's last will as the one to receive such
distributions. Distributions subsequent to the death of a Participant may be
made either in a lump sum or in periodic installments in such amounts and over
such period, not exceeding ten years from the date of death, as the Committee
may direct and the amount of each installment shall be computed as provided in
Section 6(b), and (d) as the case may be.

      (f)   Payments from the Cash Deferral Accounts shall be made in cash and
payments from the Stock Deferral Accounts shall be made in Shares. The amount of
any distribution pursuant to Sections 6 through 8 shall reduce the balance held
in the Participant's corresponding Deferral Accounts as of the date of such
distribution. Installment payments shall be made pro-rata from a Participant's
Deferral Accounts.

7. In-Service Distributions. Pursuant to Section 3 and other than for deferrals
pursuant to Sections 3(c)(iii), a Participant may elect to receive an in-service
distribution of all or any specified percentage of the Participant's deferral
election made in any year commencing not earlier than the first of the calendar
year following the fourth anniversary of the date the deferral election was
made. In-service distributions shall be made in a lump sum payment. A
Participant may elect once for any calendar year of deferral for which the
Participant has elected an in-service distribution, to change the date of
distribution to another in-service year or six (6) months after the Participant
has separated from service; provided, however, that any such modification must
be made in writing at least twelve (12) months prior to the date originally
elected for the in-service distribution; provided further that the deferred
distribution date must be at least five (5) years after the date originally
selected.

8. Acceleration of Payments. The Committee may accelerate the distribution of
part or all of one or more of a Participant's Deferral Accounts for reasons of
an unforeseeable

                                       4


emergency that cannot be met using other resources. For purposes of the Plan, an
unforeseeable emergency shall be deemed to exist in the event the Committee
determines that a Participant needs a distribution to meet a severe hardship to
the Participant resulting from a sudden or unexpected illness or accident of the
Participant or a member of the Participant's family, loss of the Participant's
property due to casualty, or other similar extraordinary and unforeseeable
circumstance arising as a result of events beyond the control of the
Participant. A distribution based on financial hardship shall not exceed the
amount required to meet the immediate financial need created by the hardship.

9. Non-assignability. None of the rights or interests in any of the
Participant's Deferral Accounts shall, at any time prior to actual payment or
distribution pursuant to the Plan, be assignable or transferable in whole or in
part, either voluntarily or by operation of law or otherwise, and such rights
and interest shall not be subject to payment of debts by execution, levy,
garnishment, attachment, pledge, bankruptcy or in any other manner.

10. Interest of Participant. The Company shall be under no obligation to
segregate or reserve any funds or other assets for purposes relating to the Plan
and, except as set forth in this Plan, no Participant shall have any rights
whatsoever in or with respect to any funds or other assets held by the Company
for purposes of the Plan or otherwise. Each Participant's accounts maintained
for purposes of the Plan merely constitute bookkeeping entries on records of the
Company, constitute the unsecured promise and obligation of the Company to make
payments as provided herein, and shall not constitute any allocation whatsoever
of any cash, shares or other assets of the Company or be deemed to create any
trust or special deposit with respect to any of the Company's assets.
Notwithstanding the foregoing provisions, nothing in this Plan shall preclude
the Company from setting aside Shares or funds in trust pursuant to one or more
trust agreements between a trustee and the Company. However, no Participant
shall have any secured interest or claim in any assets or property of the
Company or any such trust and all Shares or funds contained in such trust shall
remain subject to the claims of the Company's general creditors.

11. Amendment. The Board of Directors of the Company, or the Organization and
Compensation Committee may, from time to time, amend or terminate the Plan,
provided that no such amendment or termination of the Plan shall adversely
affect a Participant's accounts as they existed immediately before such
amendment or termination or the manner of distribution thereof, unless such
Participant shall have consented thereto in writing. Notice of any amendment or
termination of the Plan shall be given promptly to all Participants.

12. Plan Implementation. This Plan is adopted and effective for deferrals of
compensation earned for calendar years beginning on or after January 1, 2005.
