         Columbus McKinnon Corporation (the "Corporation") hereby amends the
Columbus McKinnon Corporation Thrift 401(K) Plan (the "Plan"), as amended and
restated in its entirety effective January 1, 1998, and as further amended by
Amendment Nos. 1 and 2, as permitted under Section 14.1 of the Plan, as follows:

                        Amendments Effective Before 2001

1.       Section 1.3, entitled "Actual Contribution Percentage Test or ACP
         Test", is amended effective January 1, 1997 by deleting Section 1.3(c)
         (Use of Contribution Percentage from Preceding Plan Year).

2.       Section 1.4, entitled "Actual Deferral Percentage Test or ADP Test", is
         amended effective January 1, 1997 by deleting Section 1.4(c) (Use of
         Deferral Percentage from Preceding Plan Year).

3.       Section 1.14, entitled "Eligible Employee" is amended effective January
         1, 1998 by adding the following heading to Section 1.14(d): "Exclusion
         of Certain Employees Before April 1, 1998".


4.       Section 1.19, entitled "Highly Compensated Employee", is amended
         effective January 1, 1997 by renumbering Section 1.19(b)(1)
         as Section 1.19(b)(2) and adding new Section 1.19(b)(1) to read as
         follows:

                           "(1) Meaning of "Compensation". For the purpose of
                  determining whether an Employee is a Highly Compensated
                  Employee, "Compensation" has the meaning given such term in
                  Code Section 415(c)(3) (e.g., W-2 wages increased by elective
                  deferrals etc. and not reduced by any items)."

                  incurs five (5) consecutive one-year Breaks in Service, Years
                  of Vesting Service completed after such Breaks in Service
                  shall not be taken into account in determining the Employee's
                  nonforfeitable percentage in his Account Balance derived from
                  Matching Contributions made before such 5-year period.

                           (3) Rule of Parity. If an Employee who has not become
                  partially vested in his Matching Contribution Account incurs a
                  number of consecutive one-year Breaks in Service which equals
                  or exceeds the greater of five or the aggregate number of the
                  Employee's prior Years of Vesting Service (determined without
                  regard to his age but excluding therefrom any Years of Vesting
                  Service disregarded by reason of any prior Break in Service),
                  the service credited prior to the Break in Service shall
                  thereafter be excluded from his Years of Vesting Service."

6.       Section 4.4, entitled "Distribution of Excess Contributions" is amended
         effective January 1, 1997 to read as follows:

         "4.4     Distribution of Excess Contributions.

                  (a) Required Distribution. If the Actual Deferral Percentage
         Test has not been satisfied for the Plan Year after all contributions
         have been made under the Plan for the Plan Year, the Committee shall,
         as soon as practicable but in no event later than the close of the
         following Plan Year, distribute the excess contributions, as defined in
         Section 4.4(b), to the Highly Compensated Employees in the manner
         provided in Section 4.4(c) together with an allocable share of income
         determined in accordance with Section 4.4(d). The Committee shall make
         every reasonable effort to make any distribution under this Section 4.4
         on or before March 15 of the Plan Year following the Plan Year for
         which the ADP Test was not satisfied. If such distribution includes
         contributions which qualified for Matching Contributions, the Matching
         Contributions attributable thereto shall be forfeited.

                  (b) Calculation of Excess Contributions. For purposes of this
         Section 4.4, the term "excess contributions" means the excess of--

                       (1) the aggregate amount of Salary Reduction
                  Contributions actually paid over to the Trust on behalf of
                  Highly Compensated Employees for the Plan Year, over

                       (2) the maximum amount of such contributions permitted
                  under the ADP Test (determined by reducing contributions made
                  on behalf of Highly Compensated Employees in the order of the
                  actual deferral percentages beginning with the highest of such
                  percentages).

                  (c) Distribution of Excess Contributions. Any distribution of
         excess contributions shall be made to the Highly Compensated
         Employee(s) with the highest dollar amount of Salary Reduction
         Contributions for the Plan Year in such manner that no Highly
         Compensated Employee receives a distribution of

                          Page 3 of Amendment No. 3 of the 1998 Plan Restatement


         excess contributions until the higher dollar amounts of Salary
         Reduction Contributions of all other Highly Compensated Employees (if
         any) have been distributed first. Any Matching Contributions that are
         attributable to excess contributions distributed pursuant to this
         Section 4.4 shall be forfeited and used to reduce Employer
         contributions or used to pay Plan administration expenses.

                  (d) Income (or Loss) Allocable to Excess Contributions.

                       (1) Standard Allocation Method. The income (or loss)
                  allocable to excess contributions that were distributed in
                  accordance with Section 4.4(c) shall be determined by
                  multiplying the income (or loss) allocable to the
                  Participant's Salary Reduction Contribution Account for the
                  Plan Year by a fraction [1] the numerator of which is the
                  excess contributions distributed to the Participant and [2]
                  the denominator of which is the account balance of the
                  Participant's Salary Reduction Contribution Account as of the
                  beginning of the Plan Year increased by the Participant's
                  Salary Reduction Contributions for such Plan Year.

                       (2) Alternative Allocation Method. As an alternative to
                  the standard method of allocating income (or loss) to excess
                  contributions described in Section 4.4(d)(1), the Committee
                  may use any reasonable method for computing income allocable
                  to excess contributions provided that the method does not
                  violate Code Section 401(a)(4), is used consistently for all
                  Participants and for all corrective distributions under the
                  Plan for that Plan Year, is used for allocating income to
                  Participants' Accounts, and/or satisfies such other
                  requirements as may be set forth in Treasury Regulations."

7.       Section 4.5, entitled "Distribution of Excess Aggregate Contributions"
         is amended effective January 1, 1997 to read as follows:

         "4.5     Distribution of Excess Aggregate Contributions.

                  (a) Required Distribution. If Matching Contributions for a
         Plan Year do not satisfy the Actual Contribution Percentage Test after
         all contributions have been made under the Plan for such Plan Year, the
         Committee shall, as soon as practicable but in no event later than the
         last day of the following Plan Year, distribute the excess aggregate
         contributions, as defined in Section 4.5(b), and income (or loss)
         allocable thereto to the Participants on whose behalf such excess
         aggregate contributions were made in accordance with Section 401(m)(6)
         of the Code and Treasury Regulations thereunder. The Committee shall
         make every reasonable effort to make any distribution under this
         Section 4.5 on or before March 15 of the Plan Year following the Plan
         Year for which the Actual Contribution Percentage Test was not
         satisfied.

                  (b) Calculation of Excess Aggregate Contributions. For
         purposes of this Section 4.5, the term "excess aggregate contributions"
         means the excess of--

                       (1) the aggregate amount of Matching Contributions
                  actually paid over to the Trust on behalf of Highly
                  Compensated Employees for the Plan Year, over

                       (2) the maximum amount of such contributions permitted
                  under the ACP Test (determined by reducing contributions made
                  on behalf of Highly Compensated Employees in the order of the
                  actual contribution percentages beginning with the highest of
                  such percentages).

                  (c) Distribution of Excess Aggregate Contributions. Any
         distribution of excess aggregate contributions shall be made to the
         Highly Compensated Employee(s) with the highest dollar amount of
         Matching Contributions for the Plan Year in such manner that no Highly
         Compensated Employee receives a distribution of excess contributions
         until the higher dollar amounts of Matching Contributions of all other
         Highly Compensated Employees (if any) have been distributed first.

                  (d) Income or Loss Allocable to Excess Aggregate
         Contributions. The income or loss allocable to excess aggregate
         contributions for the Plan Year shall be determined in a manner similar
         to the determination of income or loss allocable to excess
         contributions under Section 4.4(b)."

8.       Section 7.4, entitled "Investment Elections", is amended effective
         January 28, 2000 to read as follows:

         "7.4     Investment Elections.

                  (a)  Initial Election.

                       (a) Salary Reduction Contributions. Each Participant
                  shall submit an investment election designating that his
                  future Salary Reduction Contributions are to be invested in
                  one or more of the Investment Funds, in multiples of 5%, or in
                  multiples of such other percentage as may be authorized by the
                  Committee. The investment election shall be submitted in a
                  manner prescribed by the Committee. If a Participant fails to
                  submit an investment election, the Participant shall be deemed
                  to have elected 100% Guaranteed Investment Contract (GIC) Fund
                  or such other default Investment Fund as may be selected by
                  the Committee. An election under this Section 7.4(a) shall be
                  effective as of the effective date of the Participant's
                  participation in the Plan, and shall remain in effect until
                  changed in accordance with Section 7.4(b).

                       (b) Matching Contributions. A Participant's Matching
                  Contributions shall be invested in the same percentages and
                  the same Investment Funds as his Salary Reduction
                  Contributions.

                       (c) Rollover Contribution. Each Participant who makes a
                  rollover contribution shall designate in writing one or more
                  Investment Funds in which such contribution is to be invested,
                  in multiples of 5%, or in multiples of such other percentage
                  as may be authorized by the Committee. Such designation shall
                  be provided to the Committee at least 15 days before the
                  rollover is made.

                  (b) Change of Election. A Participant may change his
         investment election for future Salary Reduction Contributions by
         submitting a new investment election in a manner prescribed by the
         Committee. Such change in investment election shall be effective as
         soon as administratively reasonable, as determined by the Committee.

                  (c) Reinvestment of Existing Balances.

                       (1) In General. A Participant (including a former
                  Employee who has not received complete distribution of his
                  Accounts) may direct that all or a portion of his existing
                  balances in any Investment Fund be reinvested in one or more
                  different Investment Funds, in such percentages or fractions
                  permitted under Section 7.4(a) as he shall specify.

                       (2) When Reinvestment Becomes Effective. Transfers out of
                  or into any Investment Fund (subject to restrictions imposed
                  by individual Investment Funds) shall be given effect as soon
                  as administratively reasonable after the Participant has
                  submitted the relevant change in investment election.

                       (3) Limitations on Reinvestment. The Committee by rule of
                  general application may limit the number of elections pursuant
                  to this Section 7.4(c) that may be made during a Plan Year or
                  other period."

         to the limitations of, Code Section 414(v).

                  (b) Treated as Salary Reduction Contributions. Catch-up
         Contributions shall be treated as additional Salary Reduction
         Contributions for all purposes of the Plan except as otherwise provided
         in Code Section 414(v), regulations and other guidance issued
         thereunder, and this Section 3.4.

         not be taken into account for purposes of the provisions of the Plan
         implementing the limitations of Sections 402(g) and 415 of the Code.
         The Plan shall not be treated as failing to satisfy the provisions of

         401(k)(11), 401(k)(12), 410(b), or 416 of the Code, as applicable, by

         implement appropriate administrative procedures to deal with Catch-up
         Contributions including, without limitation, rules regarding whether
         such contributions can be made in a single sum and/or pro rata during
         the year.

                  (e) Effective Date. This Section 3.4 shall be effective as of
         January 1, 2002 or such later date, determined by the Committee in its
         discretion, when appropriate Plan administrative procedures have been
         implemented."

26.      Section 4.1, entitled "Maximum Amount of  Contributions", is amended

         "4.1 Maximum Amount of Contributions.

                  (a) Limitation on Annual Additions. In no event shall the sum

         for such Participant to exceed the amount permitted under Section 5.1,
         except to the extent permitted under Section 3.4 and Code Section
         414(v) with respect to Catch-up Contributions.

         under the Plan that must be taken into account for purposes of applying
         the Code Section 404 limitation on Employer deductions are conditioned
         on their deductibility under Code Section 404.

         shall Salary Reduction Contributions made on behalf of any Participant

         5.2 Definitions. The following terms shall have the following meanings
         for the purpose of this ARTICLE 5:

                  (a) "Annual Addition" means, in the case of any Participant
         and with respect to this Plan, the sum for any Limitation Year of all

         plans maintained by the Corporation or any Affiliate, the sum for any
         Limitation Year of all (i) employer contributions, employee
         contributions, and forfeitures, as described in Section 415(c)(2) of
         the Code and Treasury regulations thereunder, unreduced by any
         distributions of excess contributions, excess aggregate contributions,
         or excess deferrals (except as provided in Treasury Regulations under
         Code Section 415(c)(2)), and (ii) amounts described under Section
         415(l)(1) and Section 419(d)(2) of the Code credited to the
         Participant's accounts for the Limitation Year.

                  (b) "Affiliate" means an "Affiliate" as defined in Section 1.5
         except that, for purposes of this Article 5, membership in a controlled
         group of corporations shall be determined on the basis of a 50% control
         test rather than an 80% control test.

                  (c) "Taxable Compensation" means, with respect to a
         Participant for each Limitation Year, compensation as defined under
         Code Section 415(c)(3) and the Treasury Regulations thereunder. In no

         Trustee for the Limitation Year shall not be made. The Salary Reduction
         Contribution shall be paid instead to the Participant.

                  (b) Any Salary Reduction Contribution already paid to the
         Trustee for the Limitation Year shall, to the extent permitted by the
         Code and Treasury

         Regulations, be withdrawn from the Trust Fund and distributed to the
         Participant together with gains attributable to such Salary Reduction
         Contribution.

                  (c) If the Annual Addition for any Participant exceeds the
         limitations of Section 5.1 after the adjustments described in Section
         5.3(a) and Section 5.3(b), the excess amounts in the Participant's
         Accounts shall be held unallocated in a suspense account and used to
         reduce Salary Reduction Contributions for the next Limitation Year (and
         succeeding Limitation Years, as necessary) for the Participant if that
         Participant is covered by the Plan as of the end of the Limitation
         Year. However, if the Participant is not covered by the Plan as of the
         end of the Limitation Year, then the excess amounts shall be held
         unallocated in a suspense account for the Limitation Year and allocated
         and reallocated in the next Limitation Year to all of the remaining
         Participants in the Plan so as to reduce Salary Reduction Contributions
         for the next Limitation Year (and succeeding Limitation Years, as
         necessary) for all of the remaining Participants. If a suspense account
         is in existence at any time during a particular Limitation Year, other
         than the Limitation Year described in the preceding sentence, all
         amounts in the suspense account shall be allocated and reallocated to
         the Participants before any Salary Reduction Contributions are made
         under the Plan for the Limitation Year.

         5.4 Application of Code Section 415. No Annual Addition payable under
         the Plan shall exceed the applicable limitations set forth in Code
         Section 415 and the regulations thereunder, which are incorporated
         herein by this reference. Code Section 415 shall govern over any
         contrary provision in this Article 5."

         8.4 Restrictions on Distributions. Not withstanding any provision in
         the Plan to the contrary, no distribution of a Participant's Salary

         employment, death or disability, [2] termination of the Plan, [3] the
         Participant's attainment of age 59-1/2, or [4] upon hardship of the
         Participant within the meaning of Code Section 401(k)(2)(B)(IV) and

         distributions made after December 31, 2001.

                  (2) Modification of Definition of Eligible Retirement Plan.
         For purposes of the direct rollover provisions in this Section 9.4, an
         Eligible Retirement Plan shall also mean an annuity contract described
         in section 403(b) of the Code and an eligible plan under section 457(b)
         of the Code which is maintained by a state, political subdivision of a
         state, or any agency or instrumentality of a state or political
         subdivision of a state and which agrees to separately account for
         amounts transferred into such plan from this Plan. The definition of
         Eligible Retirement Plan shall also apply in the case of a distribution
         to a surviving spouse, or to a spouse or former spouse who is the
         alternate payee under a Qualified Domestic Relation Order.

                  (3) Modification of Definition of Eligible Rollover
         Distribution to Exclude Hardship Distributions. For purposes of the
         direct rollover provisions in this Section 9.4, any amount that is
         distributed on account of hardship shall not be an eligible rollover
         distribution and the distributee may not elect to have any portion of
         such a distribution paid directly to an Eligible Retirement Plan.

                  (4) Modification of Definition of Eligible Rollover
         Distribution To Include After-tax Employee Contributions. For purposes
         of the direct rollover provisions in this Section 9.4, a portion of a
         distribution shall not fail to be an Eligible Rollover Distribution
         merely because the portion consists of after-tax employee contributions
         which are not includible in gross income. However, such portion may be
         transferred only to an individual retirement account or annuity
         described in section 408(a) or (b) of the Code, or to a qualified
         defined contribution plan described in section 401(a) or 403(a) of the
         Code that agrees to separately account for amounts so transferred,
         including separately accounting for the portion of such distribution
         which is includible in gross income and the portion of such
         distribution which is not so includible"

31.      Section 10.3, entitled "Hardship Withdrawals", is amended effective
         January 1, 2002 to substitute "6-month period" for "twelve-month
         period" wherever it appears in Section 10.3(e)(2).

32.      Section 15.7, entitled "Change in the Law", is replaced effective
         January 1, 2002 with a new Section 15.7 which shall read as follows:

         "15.7 EGTRRA Amendment.

                  (a) Effective date. This Section 15.7 shall apply for purposes
         of determining whether the Plan is a top-heavy plan under Section
         416(g) of the Code for Plan Years beginning after December 31, 2001,
         and whether the Plan

         satisfies the minimum benefits requirements of Section 416(c) of the
         Code for such years. This section shall govern over any contrary
         provision in this Article 15.

                  (b) Determination of Top-Heavy Status.

                       (1) Key Employee. Key Employee means any employee or
                  former employee (including any deceased employee) who at any
                  time during the Plan Year that includes the Determination Date
                  was an officer of the Employer having annual compensation
                  greater than $130,000 (as adjusted under section 416(i)(1) of
                  the Code for plan years beginning after December 31, 2002), a
                  5-percent owner of the employer, or a 1 percent owner of the
                  employer having annual compensation of more than $150,000. For
                  this purpose, annual compensation means compensation within
                  the meaning of section 415(c)(3) of the Code. The
                  determination of who is a Key Employee will be made in
                  accordance with section 416(i)(1) of the Code and the
                  applicable regulations and other guidance of general
                  applicability issued thereunder.

                       (2) Determination of Present Values and Amounts. This
                  Section 15.7(b)(2) shall apply for purposes of determining the
                  present values of accrued benefits and the amounts of account
                  balances of employees as of the Determination Date.

                           (A) Distributions during year ending on the
                       determination date. The present values of accrued
                       benefits and the amounts of account balances of an
                       employee as of the Determination Date shall be increased
                       by the distributions made with respect to the employee
                       under the Plan and any plan aggregated with the Plan
                       under section 416(g)(2) of the Code during the 1-year
                       period ending on the determination date. The preceding
                       sentence shall also apply to distributions under a
                       terminated plan which, had it not been terminated, would
                       have been aggregated with the Plan under section
                       416(g)(2)(A)(i) of the Code. In the case of a
                       distribution made for a reason other than separation from
                       service, death, or disability, this provision shall be
                       applied by substituting 5-year period for 1-year period.

                           (B) Employees not performing services during year
                       ending on the Determination Date. The accrued benefits
                       and accounts of any individual who has not performed
                       services for the Employer during the 1-year period ending
                       on the Determination Date shall not be taken into
                       account.

                  (c) Minimum Benefits. Employer matching contributions shall be
         taken into account for purposes of satisfying the minimum contribution

         requirements of section 416(c)(2) of the Code and the Plan. The
         preceding sentence shall apply with respect to matching contributions
         under the Plan or, if the plan provides that the minimum contribution
         requirement shall be met in another plan, such other plan. Employer
         matching contributions that are used to satisfy the minimum
         contribution requirements shall be treated as matching contributions
         for purposes of the actual contribution percentage test and other
         requirements of section 401(m) of the Code."

         IN WITNESS WHEREOF, this instrument of amendment has been executed by a
duly authorized officer of the Corporation this 21st day of February, 2002.
