                         ANNUAL MEETING OF SHAREHOLDERS
                                 April 25, 2005
                                 PROXY STATEMENT

         This Proxy Statement and the accompanying Notice of Annual Meeting of
Shareholders and Proxy Card are being furnished in connection with the
solicitation of proxies by the directors of Acme United Corporation (hereinafter
called the "Company") to be used at the Annual Meeting of Shareholders of the
Company, to be held April 25, 2005, or at any adjournment thereof (the
"Meeting"). This Proxy Statement and the enclosed Proxy Card are being furnished
on or about March 30, 2005 to all holders of record of the Company's Common
Stock (the "Common Stock") as of the close of business on March 8, 2005. A copy
of the Company's 2004 Annual Report to Shareholders, including consolidated
financial statements for the fiscal year ended December 31, 2004, accompanies
this Proxy Statement.

         At the Meeting, shareholders will elect eight Directors of the Company
to serve until the next Annual Meeting. Shareholders will also act upon
proposals to adopt the 2005 Non-Salaried Director Stock Option Plan (Proposal 2)
and to amend the Company's Employee Stock Option Plan to increase the number of
shares subject to options thereunder from 150,000 to 300,000 (Proposal 3).

                        Voting Securities and Record Date

         The Board of Directors has fixed the close of business on March 8, 2005
as the record date (the "Record Date") for determination of shareholders
entitled to notice of and to vote at the Meeting. As of the Record Date, there
were 3,607,421 shares of Common Stock issued and outstanding and there were no
other voting securities of the Company outstanding. The presence at the Meeting,
in person or by proxy, of a majority of the outstanding shares of Common Stock
shall constitute a quorum for the Meeting. Each outstanding share of Common
Stock entitles the record holder thereof to one vote. Abstentions and broker
non-votes are not counted as votes cast on any matter to which they relate, but
are counted in determining the presence of a quorum.

         Election of Directors. Assuming the presence of a quorum, a plurality
of the votes cast at the Meeting is required to elect each of the nominees for
Director. Abstentions and broker non-votes will not be taken into account in
determining the outcome of the election.

         Adoption of the 2005 Non-Salaried Director Stock Option Plan. To be
approved, the proposal to adopt the 2005 Non-Salaried Director Stock Option Plan
must receive the affirmative vote of a majority of the shares of Common Stock
cast in person or by proxy at the Meeting. Uninstructed shares are not entitled
to vote on this matter and therefore broker non-votes do not affect the outcome
of the vote on this proposal. Abstentions also do not affect the outcome of the
vote on this proposal.

                                       (1)


         Amendment of the Employee Stock Option Plan. To be approved, the
proposal to increase the number of shares subject to options under the Employee
Stock Option Plan must receive the affirmative vote of a majority of the shares
of Common Stock cast in person or by proxy at the Meeting. Uninstructed shares
are not entitled to vote on this matter and therefore broker non-votes do not
affect the outcome of the vote on this proposal. Abstentions also do not affect
the outcome of the vote on this proposal.

                    Voting Rights and Solicitation of proxies

         Eligible shareholders of record may vote at the Meeting in person or by
means of the enclosed Proxy Card. You may specify your voting choices by marking
the appropriate boxes on the Proxy Card. The proxy solicited hereby, if properly
signed and returned to the Company and not revoked prior to or at the Meeting,
will be voted in accordance with the instructions specified thereon. If you
properly sign and return your Proxy Card, but do not specify your choices, your
shares will be voted by the proxy holders as recommended by the Board of
Directors.

         The Board of Directors encourages you to complete and return the Proxy
Card even if you expect to attend the Meeting. You may revoke your proxy at any
time before it is voted at the Meeting by giving written notice of revocation to
the Secretary of the Company, by submission of a proxy bearing a later date or
by attending the Meeting in person and casting a ballot.

         The proxy holders, Gary D. Penisten and Walter C. Johnsen, will vote
all shares of Common Stock represented by Proxy Cards that are properly signed
and returned by shareholders. The Proxy Card also authorizes the proxy holders
to vote the shares represented with respect to any matters not included in this
Proxy Statement that may properly be presented for consideration at the Meeting.
You must return a signed Proxy Card if you want the proxy holders to vote your
shares of Common Stock.

The cost of soliciting proxies will be borne by the Company. The Company has
retained D.F. King and Co. to solicit proxies for the Annual Meeting from
brokers, bank nominees and other institutional holders. The company has agreed
to pay $6,500 plus out of pocket expenses of D.F. King and Co. for these
services. Following the mailing of proxy solicitation materials, proxies may be
solicited by directors, officers and employees of the Company and its
subsidiaries personally, by telephone or otherwise. Such persons will not
receive any fees or other compensation for such solicitation. In addition, the
Company will reimburse brokers, custodians, nominees and other persons holding
shares of Common Stock for others for their reasonable expenses in sending proxy
materials to the beneficial owners of such shares and in obtaining their
proxies.

                                       (2)


                                   PROPOSAL 1:
                              ELECTION OF DIRECTORS

Eight Directors are to be elected at the Meeting to serve for one-year terms
until the 2006 Annual Meeting and until their respective successors are elected
and qualified. All of the nominees currently are members of our Board of
Directors. The Board of Directors knows of no reason why any nominee would be
unable to serve as Director. Each nominee has consented to being named in this
Proxy Statement and to serve if elected. The Board has determined that a
majority of the nominees are "independent directors", as such term is defined in
Section 121A of the American Stock Exchange's listing standards. If any nominee
should for any reason become unable to serve, then all valid proxies will be
voted for the election of a substitute nominee designated by the Board, or the
Board may reduce the number of Directors to eliminate the vacancy.

The following information about the nominees for election as our Directors is
based, in part, upon information furnished by the nominees.

Compensation of Directors

Directors' Fees
---------------
In 2004 all Directors who are not salaried employees received a fee of $3,000
per quarter plus $700 for each Board of Directors meeting attended. The Chairman
of the Board earned an additional $700 per meeting to compensate for the broader
responsibility and related effort. The fees earned for service on the Committees
of the Board were $600 per Committee meeting and $600 for each one-half day, or
major portion thereof, devoted to Committee work. The Chairman of each Committee
earned an additional $600 per meeting to compensate for the broader
responsibility and related effort. Effective January 1, 2005, board of director
fees were increased as follows: the quarterly fee was increased to $3,500 and
board meeting fees were increased to $800. Also, the audit committee financial
expert will receive an additional quarterly fee of $800.

                                       (5)


Stock Purchase Cash Award Plan
------------------------------
Effective February 24, 2004, the Board of Directors adopted a resolution to
implement a Stock Purchase Cash Award Plan which is intended to more closely
align the Board with long-term shareholder value.

The Plan called for a cash award to be paid to Non-Salaried Directors which
would be determined at the first Board meeting following the annual meeting. The
amount of the award is recommended to the full Board by the Chairman of the
Board, the President and Chief Executive Officer and the Chairman of the
Compensation Committee based on their evaluation of improvement in shareholder
value as indicated by share price movement, return on assets, budget
accomplishment and corporate long-range planning. All Directors receive the same
amount and individual awards would not exceed $10,000 per year. Each of the six
Non-Salaried Directors received $5,500 in 2004. Effective February 22, 2005, the
plan was amended to allow for payments only if stock options were not granted.

As the Plan title implies, Directors are expected, but not required, to buy
shares of the Company's common stock on the open market or exercise previously
granted stock options with their after-tax proceeds of the cash award.


Board of Director Meetings and Committees

The Board of Directors had seven meetings in 2004. All Directors attended at
least 75% of the aggregate of the total number of the Board meetings and
meetings of Committees of which they were a member. Board members are expected
to attend annual meetings. Six out of seven Board members attended the Annual
Meeting held in 2004. The Board of Directors has established standing Executive,
Audit, Board Oversight and Compensation committees, each of which is composed
solely of independent non-employee members of the Board of Directors. The
membership in each of these standing committees is determined from time to time
by the Chairman of the Board. The Board of Directors does not have a standing
Nominating Committee.

Executive Committee
-------------------
There is an Executive Committee of the Board of Directors, which is composed of
Mr. Penisten as Chairman, and Mr. Dunbar. The function of the Executive
Committee is to act for the Board of Directors during the intervals between
meetings of the Board. The Executive Committee did not meet in 2004.

Audit Committee
---------------
The Audit Committee assists the Board of Directors in overseeing (1) the audit
and integrity of our financial statements, (2) the performance of our
independent auditors, (3) the adequacy and effectiveness of our accounting,
auditing and financial reporting processes, and (4) our compliance with legal
and regulatory requirements. The duties of the Audit Committee include the
selection and appointment of our independent auditors, including evaluation of
their qualifications, performance and independence. The Board of Directors has
determined that all members of the Audit Committee are "independent" and
"financially literate" within the meaning of the applicable listing standards of
the American Stock Exchange. In addition, the Board has determined that Mr. Ward
qualifies as an "audit committee financial expert" within the meaning of
regulations adopted by the Securities and Exchange Commission and has the
financial sophistication required under the listing standards of the American
Stock Exchange.

                                       (6)


The Audit Committee meets at least quarterly, and more often as needed. The
Committee met four times in 2004. The Board of Directors has adopted a written
charter for the Audit Committee, which is reviewed annually by the Audit
Committee. The current Audit Committee Charter (which was last amended in March,
2005) is attached as Appendix A to this proxy statement.

Nominations for Directors
-------------------------
The functions of the Nominating Committee are performed by the whole Board.
Board of Director nominations are recommended for the entire Board's selection
by a majority of the Board's "independent directors", as such term is defined in
Section 121A of the American Stock Exchange's listing standards.

The Board will consider nominees for directors recommended in writing by
shareholders to the Board at least sixty (60) days prior to the annual meeting
at which the election of directors is to be held (subject to certain
requirements set forth in the by-laws). The nomination should be sent in care of
the Secretary at the Company's principal executive office, and should include
the name, address, telephone number and resume of his or her business and
educational background along with a written statement by the shareholder as to
why such person should be considered for election to the Board of Directors.

The Board follows the same evaluation procedures whether a candidate is
recommended by directors or shareholders. In identifying and evaluating nominees
for director, the Board considers whether the candidate has the highest ethical
standards and integrity and sufficient education, experience and skills
necessary to understand and wisely act upon the complex issues that arise in
managing a publicly-held company. To the extent the Board does not have enough
information to evaluate a candidate, the Board may send a questionnaire to the
candidate for completion in enough time for Board consideration.

Board Oversight Committee
-------------------------
On November 3, 2003, a temporary Board Oversight Committee was established to
evaluate and recommend actions related to the size of the Board and the
disciplines needed by its members. The Committee will also address (1) the
possible need for a mandatory retirement age for Directors and (2) any other
issue which it determines will improve Board performance and effectiveness. The
Committee is composed of Mr. Holden as Chairman, Mr. Dunbar and Ms. Murphy. The
committee met once during 2004.

                                       (7)


Compensation Committee
----------------------
The Company's executive compensation program is administered by the Compensation
Committee of the Board of Directors. The Committee is composed of certain
non-employee members of the Board of Directors, which include Mr. Dunbar as
Chairman, Messrs. Holden and Penisten, and Ms. Murphy. The Committee had two
meetings during 2004.


Shareholder Communications with Directors

The Company has established a process for shareholders to send communications to
the Board of Directors, as described in this section. Shareholders may direct
communications to the Secretary, Acme United Corporation, 1931 Black Rock
Turnpike, Fairfield, Connecticut 06825, who will forward them to all Board
members within a reasonable time after receipt. If the shareholder wishes the
communication to be sent to one or more specific Board members only, the
addressee should be the specific Board member(s), "c/o Secretary", who will then
forward the communication to such Board member(s). If one or more specific Board
members are not designated for such other communication, the communication will
be forwarded to the entire Board.

Retirement Plans

In December 1995, the Board of Directors adopted a resolution to freeze the
defined benefit pension plan resulting in no further benefit accruals after
February 1, 1996. The life annuity annual benefit at age 65 was zero for Walter
C. Johnsen, Brian S. Olschan, Paul G. Driscoll and Larry H. Buchtmann and $3,985
for James A. Benkovic. Amounts earned by others under this plan are not subject
to a deduction for estimated Social Security benefits, and do not include
benefits which would result from the transfer by a retiring employee of his
accrued profit-sharing account balance to the pension plan.

                                      (13)


Change in Control Arrangements -- Salary Continuation Plan

The company has a Salary Continuation Plan in effect covering officers of the
Company at the level of Corporate Vice President or above, under the age of 65.
This plan covers Walter C. Johnsen, Brian S. Olschan, James A. Benkovic, Larry
H. Buchtmann and Paul G. Driscoll and is designed to retain key employees and
provide for continuity of management in the event of an actual or threatened
change in control of the Company. The Plan provides that in the event of such a
change in control, each such key employee would have specific rights and receive
certain benefits if, within one year (or if such employee is also a director,
within two years) after such change in control, the employee is terminated
involuntarily, the employee's responsibility, status or compensation is reduced,
the employee is transferred to a location unreasonably distant from his/her
current location or the employee voluntarily resigns. In such circumstances, the
compensation which the employee would be entitled to receive would be a lump sum
payment equal to a specific number of months' compensation. Compensation
includes the employee's monthly salary rate being paid at the date of
disposition times the number of months payable and the average monthly incentive
bonus payments for the prior three taxable years times the number of months
payable. Also, medical, life and other insurance that was in effect at the date
of disposition will continue into the future for the number of months
compensation is payable. Under the Plan Messrs. Johnsen and Olschan would be
entitled to thirty-six (36) months benefits and Messrs. Benkovic, Buchtmann and
Driscoll would be entitled to twenty-four (24) months benefits.

Severance Pay Plan

The Company has a Severance Pay Plan in effect covering officers of the Company
employed in the United States at the level of Vice President or above, under the
age of 65. This Plan covers Messrs. Johnsen, Olschan, Benkovic, Buchtmann and
Driscoll and is designed to enable the Company to attract and retain key
employees. The Plan provides that in the event the key employee's employment is
terminated by the Company involuntarily for any reason other than gross
misconduct, his/her responsibility, status or compensation is reduced, or he/she
is transferred to a location unreasonably distant from his/her current location,
he/she shall be entitled to benefits under the Plan. In such circumstances, the
compensation which the employee would be entitled to receive would be a lump sum
payment equal to one months' compensation for each year of service to the
Company based upon the level of his/her compensation in effect immediately
preceding such termination. The Plan sets out a minimum and maximum number of
months' compensation payable to each such employee upon such severance. Under
the Plan Messrs. Johnsen and Olschan would be entitled to a minimum of (9)
months' compensation and a maximum of thirty (30) months' compensation. Messrs.
Benkovic, Buchtmann and Driscoll would be entitled to a minimum of six (6)
months' compensation and a maximum of eighteen (18) months' compensation. This
plan applies only if the Salary Continuation Plan does not apply. Death benefits
are also covered by this Plan. Under the Plan, the beneficiaries of Messrs.
Johnsen and Olschan would receive nine (9) months' compensation and the
beneficiaries of the other officers would receive six (6) months' compensation.

Compensation Committee Report on Executive Compensation

The Compensation Committee is committed to a strong, positive link between
business, performance and strategic goals, and compensation and benefit
programs.

                                      (15)


Overall Executive Compensation Policy
-------------------------------------
Our compensation policy is designed to support the overall objective of
enhancing value for our shareholders by:

          -    Attracting, developing, rewarding and retaining highly qualified
               and productive individuals.

          -    Directly relating compensation to both Company and individual
               performance.

          -    Ensuring compensation levels that are externally competitive and
               internally equitable.

Following is a description of the elements of the Company's executive
compensation program and how each relates to the objectives and policy outlined
above.

Base Salary
-----------
The Committee reviews each executive officer's salary annually. In determining
appropriate salary levels, we consider level and scope of responsibility,
experience, company and individual performance, internal equity, as well as pay
practices of other companies relating to executives of similar responsibility.

By design, we strive to set executives' salaries at competitive market levels.

Annual Incentives
-----------------
Annual incentive award opportunities are made available to executives to
recognize and reward corporate and individual performance. The plan in effect
for 2004 provided for an incentive bonus based on the achievement of corporate
profitability goals and objectives set for each individual, based upon his/her
area of responsibility. The amount individual executives may earn under the
bonus plan is directly dependent upon the individual's position, responsibility
and ability to impact our financial success and corporate goals. The bonuses
awarded in 2004 to top management are listed in the Summary Compensation Table.

Stock Option Incentives
-----------------------
The Company's stock option compensation program is administered by the Board of
Directors, which acts upon recommendations of the Compensation Committee. The
purpose of the Company's Employee Stock Option Plan is to promote the interests
of the Company by enabling its key employees to acquire an increased proprietary
interest in the Company and thus to share in the future success of the Company's
business. Accordingly, the plan is intended as a means not only of attracting
and retaining outstanding management personnel but also of promoting a closer
identity of interests between employees and shareholders. Since the employees
eligible to receive options under the plan will be those who are in a position
to make important and direct contributions to the success of the Company, the
Board believes that the grant of options under the plan has been and will
continue to be in the best interests of the Company.

The Company's Amended and Restated Stock Option Plan terminated on February 24,
2002 and options granted under that Plan continue to vest and to be exercisable
in accordance with their terms; however, no new options may be granted under the
Plan after February 24, 2002.

                                      (16)


The Company adopted a new stock option plan, Employee Stock Option Plan,
effective February 26, 2002 authorizing the grant of options to purchase up to a
total of 150,000 shares of common stock. No options were granted in 2004 to
officers of the Company.


Rationale for CEO Compensation
------------------------------
Walter C. Johnsen was designated President and Chief Executive Officer of the
Company effective on November 30, 1995. His compensation package was designed to
encourage performance in line with the interests of our shareholders. We believe
Mr. Johnsen's total compensation was competitive in the external marketplace and
reflective of Company and individual performance.

Certain Transactions

There were no material transactions between the Company and any officer of the
Company, any director or nominee for election as director, any security holder
holding more than 5% of the Common Stock of the Company or any relative or
spouse of any of the foregoing persons.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
directors and executive officers, and persons who own more than 10% of a
registered class of the Company Common Stock (collectively referred to herein as
"Reporting Persons"), to file with the SEC and the American Stock Exchange
initial reports of ownership and reports of changes in ownership of Common Stock
and other equity securities of the Company. Reporting Persons are required by
SEC regulation to furnish the Company with copies of all Section 16(a) forms
they file. Based solely on review of copies of such forms received by the
Company or written representations from Reporting Persons, the Company believes
that, during the 2004 fiscal year, all Reporting Persons complied with all
applicable filing requirements under Section 16(a).

Performance Graph

The following Performance Graph shall not be deemed incorporated by reference by
any general statement incorporating by reference this proxy statement into any
filing under the Securities Act of 1933 or the Securities Exchange Act of 1934,
except to the extent that the Company specifically incorporates this information
by reference, and shall not otherwise be deemed filed under such Acts.

The graph compares the yearly cumulative total shareholder return on the
Company's Common Stock with the yearly cumulative total return of (a) the AMEX
Market Index and (b) a peer group of companies that, like the Company, (i) are
currently listed on the American Stock Exchange, and (ii) have a market
capitalization of $45 million to $55 million.

The Company does not believe it can reasonably identify a peer group of
companies on an industry or line-of-business basis for the purpose of developing
a comparative performance index. While the Company is aware that some other
publicly-traded companies market products in the Company's line-of-business,
none of these other companies provide most or all of the products offered by the
Company, and many offer other products or services as well. Moreover, some of
these other companies that engage in the Company's line-of-business do so
through divisions or subsidiaries that are not publicly-traded. Furthermore,
many of the other companies are substantially more highly capitalized than the
Company. For these reasons, any such comparison would not, in the opinion of the
Company, provide a meaningful index of comparative performance.

                                  PROPOSAL TWO:
            ADOPTION OF 2005 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

On February 22, 2005, the Board of Directors adopted, subject to approval of the
Shareholders, the 2005 Non-Salaried Director Stock Option Plan ("Plan"). The
following description of the Plan is qualified in its entirety by reference to
the text of the Plan, a copy of which is attached hereto as Exhibit B. The plan
replaces the 1996 Non-Salaried Director Plan once all shares currently unused
are granted. Under the 1996 Non-Salaried Director Plan 160,000 shares were
authorized of which 152,500 shares have been used.

Purpose

The purpose of the Plan is to provide long-term incentive supplemental
compensation for members of the Board of Directors of the Company who are not
employees of the Company through the ownership of the Company's Common stock,
thereby further aligning their interest with the interests of shareholders.
Stock option plans for non-employee directors have served Acme United and its
shareholders well by directly relating incentive compensation to the building of
long term shareholder values.

Administration of the Plan

The plan will be administered by the Compensation Committee of the Board of
Directors composed of non-employee directors (the "Committee").

Shares of Stock Subject to the Plan

The aggregate number of shares that may be subject to options during the term of
the Plan is limited to 50,000 shares of the Common Stock of the Company. This
limit may not be increased during the term of the Plan except by equitable
adjustment following recapitalization, stock splits, stock dividends or any
similar adjustment in the number of shares subject to outstanding options, and
in the related option exercise price. If the shareholders approve this Plan,
additional shares (which can be authorized but un-issued shares or treasury
shares or a combination thereof) will be reserved for the award of options.

                                      (19)


Eligibility

All Non-Salaried Directors of the Company are eligible to participate in the
Plan.

Duration of the Plan

No awards of stock options may be made under the Plan after May 31, 2015.
Applicable provisions will continue in effect thereafter with respect to all
unexercised options outstanding prior to that date.

Options

Under the terms of the Plan, each Non-Employee Director would annually be
granted an option to purchase 2,500 shares of Common Stock. Each newly appointed
Non-Employee Director would receive an initial option to purchase 5,000 shares
of common stock, and thereafter would annually, along with the other
Non-Employee Directors, receive an option to purchase 2,500 shares of Common
Stock. Under the Plan, the Board of Directors has the authority to increase or
decrease the number of shares of Common Stock which are the subject of such
annual or initial option grants.

The terms of the options shall, at the time of the grant, provide that the
options will not be treated as incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986 (the "Code"), as amended.

The exercise price with respect to an option awarded under the Plan will be 100%
of the fair market value of the Common Stock as of the date the option is
granted. It will be paid for in full, in cash or in any other medium and manner
satisfactory to the Company at the time the option is exercised. The optionee
must satisfactorily provide for the payment of any taxes which the Company is
obligated to collect or withhold before the Common Stock is transferred to the
optionee.



Terms of Exercise of Options

Options may not be exercised until they vest (ranges from immediately to three
years) and not after ten years from the date of the grant, except in the case of
death or disability of the grantee in which case, the option may be exercised
within 12 months of the death or disability. The Committee may make provision
for exercises within the 10-year term of a grant. Recipients will have no rights
as stockholders until the date of exercise in the case of an exercise involving
receipt of stock. Options may not be transferred except upon the death of the
grantee.

Amendment to the Plan

Without further approval of the shareholders, the Board may discontinue the Plan
at any time and may amend it from time to time in such respect as the Board may
deem advisable including the initial and annual numbers of options granted,
unless shareholder or regulatory approval is required by law or regulation and
subject to any conditions established by the terms of such amendment; provided,
however, that the Plan may not be amended 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.

                                      (20)


Federal Income Tax Consequences

Granting of Options
-------------------
A recipient of options incurs no income tax liability as a result of having been
granted those options or rights.

Exercise of Options
-------------------
The exercise by an individual of a stock option normally results in the
immediate realization of ordinary income subject to self-employment tax by the
individual in an amount equal to the excess of (i) the fair market value of the
stock which is being purchased on the date of exercise over (ii) the price being
paid for such stock.

Sale of the Stock
-----------------
Under current law an individual who sells stock which was acquired upon the
exercise of options will receive long-term capital gains or loss treatment, if
he or she has held such stock for longer than one year following the date of
such exercise. The gain or loss from the sale will be equal to the difference
between the price for which such stock was sold and the market value of the
stock on the date of the exercise. If the individual has held the stock for one
year or less the gain or loss will be treated as short-term capital gain or
loss.


Plan Benefits

On February 22, 2005, the Board of Directors voted to issue stock options to
Non-Salaried Board members if an adequate number of shares were approved by the
shareholders. If stock options are not approved for granting, the Stock Purchase
Cash Award Plan applies.

Option grants under the Plan by outside director in 2005 will be as follows:

                                      (21)


Vote Required

The plan described requires the affirmative vote of a majority of the shares of
Common Stock of the Company voting in person or by proxy on the amendment. If
the plan is not approved by shareholders, it will not become effective.

The Board of Directors recommends a vote FOR approval of the 2005 Non-Salaried
Director Stock Option Plan.


                                 PROPOSAL THREE:
                    AMENDMENT TO EMPLOYEES' STOCK OPTION PLAN

On February 22, 2005, the Board of Directors, subject to approval of the
Shareholders, amended the Employee Stock Option Plan effective February 26, 2002
(the "Plan") to increase the number of shares subject to options from 150,000 to
300,000. The Company proposes that the number of shares of Common Stock reserved
for issuance under the Plan be so increased in order to enable the Company to
continue to attract and retain highly qualified personnel. The following
description of the Plan as amended is qualified in its entirety by reference to
the text of the Plan and its prior amendments, copies of which have been filed
with the SEC.

Purpose

The purpose of the Plan is to advance the interests of the Company and its
shareholders by strengthening the ability of the Company to attract, retain and
reward highly qualified key employees, to motivate key employees to achieve
business objectives established to promote the long-term growth, profitability
and success of the Company, and to encourage ownership of the Common Stock of
the Company by participating key employees.

Administration of the Plan

The Plan is administered by the Board of Directors of the Company. In
administering the Plan, the Board acts upon recommendations of the Compensation
Committee, which consists of members of the Board who are not employees of the
Company. Subject to the provisions of the Plan, the Board determines the
employees who will receive options under the Plan, the number of shares subject
to each option and the terms of those options, and interprets the Plan and makes
such rules of procedure as the Board may deem proper.

Shares of Stock Subject to the Plan

The Plan presently permits the granting of 150,000 shares of Common Stock
(300,000 shares after approval of amendment).

Eligibility

Based on current staffing, under the Plan, approximately 25 to 30 key employees
of the Company (including directors and officers who are employees) may be
granted options to purchase shares of Common Stock.

                                      (22)


Options

Options granted under the Plan may be either incentive stock options within the
meaning of Section 422 of the Internal Revenue Code of 1986, as amended, or
non-qualified stock options. The exercise price with respect to an option
awarded under the plan will be one hundred percent (100%) of the fair market
value of the Common Stock on the date that the option is granted provided,
however, that the price shall not be less than the par value of the Common Stock
which is subject to the option. If incentive stock options are granted to an
employee owning Common Stock having more than 10% of the voting power of the
Company, the exercise price must be at least one hundred ten percent (110%)
instead of one hundred percent (100%) of the fair market value of the Common
Stock on the date that the option is granted, and the option by its terms may
not be exercisable after the expiration of five (5) years from the date of
grant. No option may be granted under the Plan after the tenth anniversary of
the adoption of the Plan. Unless otherwise specified by the Board, options
granted under the Plan are Incentive Stock Options under the provisions and
subject to the limitations of Section 422 of the Internal Revenue Code.


Terms of Exercise of Options

Upon the granting of any option, the optionee must enter into a written
agreement with the Company setting forth the terms upon which the option may be
exercised. Such an agreement sets forth the length of the term of the option and
the timing of its exercise as determined by the Board, and may provide
arrangements for income and employment tax withholding. Under terms of the Plan,
options are exercisable in accordance with the following schedule: 25% on the
day after the date of the grant; 25% one day after first year anniversary of the
date of grant; 25% one day after second year anniversary of date of grant; 25%
one day after third year anniversary of date of grant. In no event shall the
length of an option extend beyond ten years from the date of its grant. An
optionee may exercise an option by delivering payment to the Company in cash.

Under the Plan, if the employment of any person to whom an option has been
granted is terminated for any reason other than the death, disability or
retirement of the optionee, the optionee may exercise within thirty (30) days of
such termination such options as the optionee could have exercised if his or her
employment had continued for such 30 day period subject to the ten year
limitation. If the termination is by reason of retirement, the optionee may
exercise the option, in whole or in part, at any time within one year following
such termination of employment, subject to the ten year limitation, but if the
option is exercised later than three (3) months from the date of retirement the
option shall not constitute an Incentive Stock Option. If the optionee dies
while employed by the Company or its subsidiaries, or during a period after
termination of employment in which the optionee could exercise an option, the
optionee's beneficiary may exercise the option within one year of the date of
the optionee's death but in no event may the option be exercised later than the
date on which the option would have expired if the optionee had lived. If the
termination is by reason of disability, the optionee may exercise the option, in
whole or in part, at any time within one year following such termination of
employment or within such other period, not exceeding three years after the date
of disability, as is set forth in the option agreement with respect to such
options, provided, however, that if the option is exercised later than one year
after the date of disability, it shall not constitute an Incentive Stock Option,
and in no event may the option be exercised after ten years from grant.

                                      (23)


In addition, if an optionee ceases to be employed by the Company and becomes, or
continues to be, a member of the Board of Directors prior to the time the
optionee's option(s) would have otherwise expired, the optionee's option(s)
shall continue to vest in accordance with the terms of the Plan and shall
continue to be exercisable for the remainder of the term of the option(s). Any
option which is not exercised by the optionee within the three month period
immediately following the optionee's termination of employment, or, in the case
of termination of employment on account of disability, within one year after the
date of disability, shall cease to be an Incentive Stock Option. If an optionee
described in the preceding two sentences ceases to be a member of the Board of
Directors for any reason, the optionee's option(s) shall terminate in accordance
with the provisions of Section 2.4(a) of the Acme United Corporation
Non-Salaried Director Stock Option Plan, which section (i) cancels any unvested
options at that time; (ii) permits a twelve-month period for exercise of vested
options in the event of termination due to death or disability; and (iii)
permits a thirty-day period for exercise of vested options in the event of
termination due to any other reason, except that the Board may in its discretion
extend the period of exercise.

Notwithstanding the above, no option may be exercised after the expiration date
specified in the option agreement.

Amendment to the Plan

The Plan may be terminated, suspended, or modified at any time by the Board of
Directors, but no amendment increasing the maximum number of shares for which
option may be granted (except to reflect a stock split, stock dividend or other
distribution), reducing the option price of outstanding options, extending the
period during which options may be granted, otherwise materially increasing the
benefits accruing to optionees or changing the class of persons eligible to be
optionees shall be made without first obtaining approval of the shareholders of
the Company. No termination, suspension or modification of the Plan shall
adversely affect any right previously acquired by the optionee or other
beneficiary under the Plan.

Options granted under the Plan may not be transferred other than by will or by
the laws of descent and distribution and, during the optionee's lifetime may be
exercised only by the optionee.

All of the Options previously issued under the prior plan remain unchanged and
outstanding.

Federal Income Tax Consequences

Granting of Non-Qualified Stock Options
---------------------------------------
With respect to the tax effects of non-qualified stock options, since the
options granted under the Plan do not have a "readily ascertainable fair market
value" within the meaning of the Federal income tax laws, an optionee of an
option will realize no taxable income at the time the option is granted.

                                      (24)


Exercise of Non-Qualified Stock Options
---------------------------------------
When a non-qualified stock option is exercised, the optionee will generally be
deemed to have received compensation, taxable at ordinary income tax rates, in
an amount equal to the excess of the fair market value of the shares of Common
Stock of the Company on the date of exercise of the option over the option
price. The Company will withhold income and employment taxes in connection with
the optionee's recognition of ordinary income as a result of the exercise by an
employee/optionee of a non-qualified stock option, and arrangements must be made
with the Company for the source of such withholding. The Company generally can
claim an ordinary deduction in the fiscal year of the Company which includes the
last day of the taxable year of the optionee which includes the exercise date or
the date on which the optionee recognizes income. The amount of such deduction
will be equal to the ordinary income recognized by the optionee.

Sale of the Stock
-----------------
When stock acquired through the exercise of a non-qualified stock option is
sold, the difference between the optionee's basis in the shares and the sale
price will be taxable to the optionee as a capital gain (or loss).

Granting of Incentive Stock Options and Exercise of Incentive Stock Options
----------------------------------------------------------------------------
With respect to the tax effects of Incentive Stock Options, the optionee does
not recognize any regular taxable income when the option is granted or
exercised; however, the excess of the fair market value of the stock on the date
of exercise over the exercise price must be included in the optionee's
alternative minimum taxable income. Depending on the optionee's other income and
deductions, all or a portion or this excess could be subject to alternative
minimum tax of as much as twenty eight percent (28%).


Sale of the Stock
-----------------
If no disposition of shares issued to an optionee pursuant to the exercise of an
Incentive Stock Option is made by the optionee within two years after the date
the option was granted or within one year after the shares were transferred to
the optionee, then (a) upon sale of such shares, any amount realized in excess
of the option price (the amount paid for the shares) will be taxed to the
optionee as long-term capital gain and any loss sustained will be a long-term
capital loss and (b) no deduction will be allowed to the Company for Federal
income tax purposes. The tax basis of the stock for alternative minimum tax
purposes shall be the fair market value of the stock on its date of exercise,
and the optionee may be entitled to a credit if its alternative minimum tax is
less than its regular tax in the year of sale.

If shares of Common Stock acquired upon the exercise of an Incentive Stock
Option are disposed of prior to the expiration of the two year and one year
holding periods described above (a "Disqualifying Disposition") generally (a)
the optionee will realize ordinary income in the year of disposition in an
amount equal to the excess (if any) of the fair market value of the shares at
exercise (or, if less, the amount realized upon the sale of such shares) over
the option price thereof, and (b) the Company will be entitled to deduct such
amount. Any further gain realized will be taxed as short-term or long-term
capital gain and will not result in any deduction by the Company. A
Disqualifying Disposition in the same year as exercise will eliminate the
alternative minimum tax adjustment associated with the exercise of the Incentive
Stock Option.

                                      (25)


Plan Benefits

The benefits or amounts that will be received by or allocated to any
participants are not now determinable.

Vote Required

The approval of the amendment to the Employee Stock Option Plan requires the
affirmative vote of a majority of the shares of Common Stock of the Company
voting in person or by proxy on the amendment. If the amendment is not approved
by shareholders, it will not become effective.

The Board of Directors recommends a vote FOR approval of the amendment to the
Employee Stock Option Plan.


                              SELECTION OF AUDITORS

The Audit Committee has reappointed Ernst & Young LLP as independent auditors to
audit the financial statements of the Company for the current fiscal year.

Representatives of Ernst & Young LLP are expected to be present at the 2005
Annual Meeting with the opportunity to make a statement if they desire to do so
and are expected to be available to respond to appropriate questions. The
Company knows of no direct or material indirect financial interest in the
Company or of any connection with the Company by this accounting firm except the
professional relationship between auditor and client.


             POLICY ON PRE-APPROVAL OF INDEPENDENT AUDITOR SERVICES

The Audit Committee pre-approves all audit and permissible non-audit services
provided by the independent auditors. These services may include audit services,
audit-related services, tax services and other services. The Audit Committee has
adopted policies and procedures for the pre-approval of services provided by the
independent auditors. The policies and procedures provide that management and
the independent auditors jointly submit to the Audit Committee a schedule of
audit and non-audit services for approval as part of the annual plan for each
year. In addition, the policies and procedures provide that the Audit Committee
may also pre-approve particular services not in the annual plan on a
case-by-case basis. For each proposed service, management must provide a
detailed description of the service and the projected fees and costs (or a range
of such fees and costs) for the service.

Beginning May 6, 2003 and on an ongoing basis, the Audit Committee is required
to pre-approve all services rendered by the Company's independent auditors prior
to the engagement of the auditors with respect to such services. During 2003 and
2004, the Audit Committee pre-approved all services with the exception of
certain tax advice projects which had begun prior to May 6, 2003 (the effective
date of the pre-approval requirements for audit committees).

                                      (26)


                                FEES TO AUDITORS

Set forth below is a description of the fees for professional audit services
rendered by Ernst & Young for the audit of our annual financial statements and
review of our interim financial statements for 2003 and 2004, and fees for other
services rendered by Ernst & Young for 2003 and 2004.

Audit Fees

         Audit fees for the 2003 and 2004 audits were $168,000 and $186,000,
respectively.

Audit Related Fees

         Audit related fees for 2003 and 2004 were $18,000 and $5,000,
respectively. These fees were for pension audits and financial reporting
consultation.

Tax Fees

         Tax fees for tax services in 2003 and 2004 were $56,000 and $35,000,
respectively. Tax services included tax compliance, tax advice, and tax
planning.

All other Fees

         None.

The Audit Committee has determined that the provision of non-audit services
described above is compatible with maintaining Ernst & Young's independence.



          DEADLINE FOR SUBMISSION OF SHAREHOLDER PROPOSALS FOR THE 2006

                                      (27)

APPENDIX A

Acme United Corporation
Audit Committee Charter

Organization

This charter governs the operations of the Audit Committee. The Board of
Directors shall appoint an Audit Committee (the "Committee") of at least three
members, consisting entirely of independent directors of the Board. For purposes
hereof, members shall be considered independent as long as they satisfy all of
the independence requirements for Board Members as set forth in the applicable
stock exchange listing standards and Rule 10A-3 of the Exchange Act.

Each member of the Committee shall be financially literate and at least one
member shall be an "audit committee financial expert," as defined by SEC rules.

Members shall not serve on more than three public company audit committees
simultaneously.

The Committee shall meet at least quarterly. The Committee shall meet separately
and periodically with management, the personnel responsible for the internal
audit function, and the independent auditor. The Committee shall report
regularly to the Board of Directors with respect to its activities.

                                      (28)


Purpose

The purpose of the Committee shall be to:

     o    Provide assistance to the Board of Directors in fulfilling their
          oversight responsibilities relating to: (i) the audit and integrity of
          the Company's financial statements; (ii) the qualifications,
          independence and performance of our independent auditors (iii) the
          adequacy and effectiveness of our accounting, auditing and financial
          reporting processes, including the performance of our internal audit
          functions, and (iv) the Company's compliance with legal and regulatory
          requirements; and

     o    Prepare the Audit Committee report that SEC proxy rules require to be
          included in the Company's annual proxy statement.

The Committee shall have the authority to engage independent legal, accounting
and other advisers as it deems necessary to carry out its duties.

In fulfilling its purpose, it is the responsibility of the Committee to maintain
free and open communication between the Committee, independent auditors, the
internal auditors, and management of the Company, and to determine that all
parties are aware of their responsibilities.

                                      (29)


Duties and Responsibilities

The Committee has the responsibilities and powers set forth in this Charter.
Management is responsible for the preparation, presentation, and integrity of
the Company's financial statements, for the appropriateness of the accounting
principles and reporting policies that are used by the Company and for
implementing and maintaining internal control over financial reporting. The
independent auditors are responsible for auditing the Company's financial
statements and internal control over financial reporting, and for reviewing the
Company's unaudited interim financial statements.

Although the Committee has the authority and responsibilities set forth in this
charter, the primary role of the Committee is oversight. It is not the duty of
the Committee to conduct audits, to determine that the Company's financial
statements are complete and accurate and are in accordance with generally
accepted accounting principles and applicable laws, rules and regulations, or to
otherwise assure the Company's compliance with applicable laws, rules and
regulations. These are the respective responsibilities of management and the
independent auditor.

The Committee, in carrying out its responsibilities, believes its policies and
procedures should remain flexible, in order to best react to changing conditions
and circumstances. The Committee will take appropriate actions to set the
overall corporate "tone" for quality financial reporting, sound business risk
practices, and ethical behavior.

The following shall be the principal duties and responsibilities of the
Committee. These are set forth as a guide with the understanding that the
Committee may supplement them as appropriate.

     o    The Committee shall be directly responsible for the appointment,
          compensation, retention, and oversight of the work of the independent
          auditors (including resolution of disagreements between management and
          the auditor regarding financial reporting) for the purpose of
          preparing or issuing an audit report or performing other audit,
          review, or attest services for the Company, and the independent
          auditors must report directly to the Committee.

     o    The Committee shall ensure that the independent auditor annually
          submits to the Committee a report delineating all relationships
          between the auditor and the Company consistent with Independence
          Standards Board Standard No. 1. The Committee shall actively engage in
          a dialogue with the auditor with respect to any disclosed
          relationships or services that may impact the objectivity and
          independence of the auditor. The Committee shall take or recommend
          that the full Board of Directors take appropriate action to oversee
          the independence of the outside auditor.

     o    After reviewing the foregoing report and the independent auditors'
          work throughout the year, the Committee shall evaluate the auditors'
          qualifications, performance and independence. Such evaluation should
          include the review and evaluation of the lead partner of the
          independent auditors and take into account the opinions of management
          and the Company's personnel responsible for the internal audit
          function.

                                      (30)


     o    The Committee shall determine that the independent audit firm has a
          process in place to address the rotation of the lead audit partner and
          other audit partners serving the account as required under the SEC
          independence rules.

     o    The Committee shall pre-approve all audit and non-audit services
          provided by the independent auditors and shall not engage the
          independent auditors to perform non-audit services proscribed by law
          or regulation. The Committee may delegate pre-approval authority to a
          member of the Audit Committee. The decisions of any Committee member
          to whom pre-approval authority is delegated must be presented to the
          full Committee at its next scheduled meeting.

     o    The Committee shall discuss with the internal auditors and the
          independent auditors the overall scope and plans for their respective
          audits, including the adequacy of staffing and budget or compensation.

     o    The Committee shall regularly review with the independent auditors any
          audit problems or difficulties encountered during the course of the
          audit work, including any restrictions on the scope of the independent
          auditors' activities or access to requested information, and
          management's response. The Committee should review any accounting
          adjustments that were noted or proposed by the auditors but were
          "passed" (as immaterial or otherwise); any communications between the
          audit team and the audit firm's national office respecting auditing or
          accounting issues presented by the engagement; and any "management" or
          "internal control" letter issued, or proposed to be issued, by the
          audit firm to the Company.

     o    The Committee shall review and discuss the quarterly financial
          statements, including Management's Discussion and Analysis of
          Financial Condition and Results of Operations, with management and the
          independent auditors prior to the filing of the Company's Quarterly
          Report on Form 10-Q. Also, the Committee shall discuss the results of
          the quarterly review and any other matters required to be communicated
          to the Committee by the independent auditors under generally accepted
          auditing standards.

     o    The Committee shall review and discuss the annual audited financial
          statements, including Management's Discussion and Analysis of
          Financial Condition and Results of Operations, with management and the
          independent auditors prior to the filing of the Company's Annual
          Report on Form 10-K (or the annual report to shareholders if
          distributed prior to the filing of Form 10-K). The Committee's review
          of the financial statements shall include: (i) major issues regarding
          accounting principles and financial statement presentations, including
          any significant changes in the company's selection or application of
          accounting principles, and major issues as to the adequacy of the
          company's internal controls and any specific remedial actions adopted
          in light of material control deficiencies; (ii) discussions with
          management and the independent auditors regarding significant
          financial reporting issues and judgments made in connection with the
          preparation of the financial statements and the reasonableness of
          those judgments; (iii) consideration of the effect of regulatory
          accounting initiatives, as well as off-balance sheet structures on the
          financial statements; (iv) consideration of the judgment of both
          management and the independent auditors about the quality, not just
          the acceptability of accounting principles; and (v) the clarity of the
          disclosures in the financial statements. Also, the Committee shall
          discuss the results of the annual audit and any other matters required
          to be communicated to the Committee by the independent auditors under
          professional standards.

                                      (31)


     o    The Committee shall receive and review a report from the independent
          auditors, prior to the filing of the Company's Annual Report on Form
          10-K (or the annual report to shareholders if distributed prior to the
          filing of Form 10-K), on all critical accounting policies and
          practices of the Company; all material alternative treatments of
          financial information within generally accepted accounting principles
          that have been discussed with management, including the ramifications
          of the use of such alternative treatments and disclosures and the
          treatment preferred by the independent auditor; and other material
          written communications between the independent auditors and
          management.

     o    The Committee shall review and approve all related party transactions.

     o    The Committee shall review and discuss earnings press releases, as
          well as financial information and earnings guidance provided to
          analysts and rating agencies.

     o    The Committee shall review any required management assessment of the
          effectiveness of the Company's internal control over financial
          reporting and any independent auditors' report on such assessment.

     o    The Committee shall discuss with management, the internal auditors,
          and the independent auditors the adequacy and effectiveness of
          internal control over financial reporting, including any significant
          deficiencies or material weaknesses identified by management of the
          Company in connection with its required quarterly certifications under
          Section 302 of the Sarbanes-Oxley Act. In addition, the Committee
          shall discuss with management, the internal auditors, and the
          independent auditors any significant changes in internal control over
          financial reporting that are disclosed, or considered for disclosures,
          in the Company's periodic filings with the SEC.

     o    The Committee shall review the Company's compliance systems with
          respect to legal and regulatory requirements and review the Company's
          code of conduct and programs to monitor compliance with such programs.
          The Committee shall receive corporate attorneys' reports of evidence
          of a material violation of securities laws or breaches of fiduciary
          duty.

     o    The Committee shall discuss the Company's policies with respect to
          risk assessment and risk management, including the risk of fraud. The
          Committee also shall discuss the Company's major financial risk

          such exposures.

                                      (32)


     o    The Committee shall establish procedures for the receipt, retention,
          and treatment of complaints received by the Company regarding
          accounting, internal accounting controls, or auditing matters, and the
          confidential, anonymous submission by employees of the Company of
          concerns regarding questionable accounting or auditing matters.

     o    The Committee shall set clear hiring policies for employees or former
          employees of the independent auditors that meet the SEC regulations
          and stock exchange listing standards.

     o    The Committee shall determine the appropriate funding for payment of:
          (1) compensation to the independent audit firm engaged for the purpose
          of preparing or issuing an audit report or performing other audit,

EXHIBIT B

         ACME UNITED CORPORATION NON-SALARIED DIRECTOR STOCK OPTION PLAN
                                 April 25, 2005

I.    GENERAL

      1.1   Purpose of the Plan

      The purpose of the Acme United Corporation Non-Salaried Director Stock
Option Plan (the "Plan") is to enable Acme United Corporation (the "Company") to
attract and retain persons of exceptional ability to serve as directors of the
Company and to align the interests of directors and shareholders in enhancing
the value of the Company's common stock (the "Common Stock").

      This Plan replaces the Non-Salaried Director Stock Option Plan of April
22, 1996 once all unused options under that plan have been granted.

                                      (33)


      1.2   Administration of the Plan

      The Plan shall be administered by the Compensation Committee or its
successors (the "Committee") of the Company's Board of Directors (the "Board")
which shall have full and final authority in its discretion to interpret,
administer and amend the provisions of the Plan; to adopt rules and regulations
for carrying out the Plan; to decide all questions of fact arising in the
application of the Plan; and to make all other determinations necessary or
advisable for the administration of the Plan. The Committee shall consist of at
least two persons and shall meet once each fiscal year, and at such additional
times as it may determine or as is requested by the chief executive officer of
the Company.

      1.3   Eligible Participants

      Commencing April 25, 2005 each member of the Board who is not a salaried
employee of the Company or any of its subsidiaries shall be a participant (a
"Participant") in the Plan.

      1.4   Grants Under the Plan

      Grants under the Plan shall be in the form of stock options as described
in Section II (an "Option" or "Options").

      1.5   Shares

      The aggregate number of shares of Common Stock, including shares reserved
for issuance pursuant to the exercise of Options, which may be issued under the
terms of the Plan, may not exceed 50,000 shares and hereby are reserved for such
purpose. Whenever any outstanding grant or portion thereof expires, is canceled
or forfeited or is otherwise terminated for any reason without having been
exercised, the Common Stock allocable to the expired, forfeited, canceled or
otherwise terminated portion of the grant may again be the subject of further
grants hereunder.

      Notwithstanding the foregoing, the number of shares of Common Stock
available for grants at any time under the Plan shall be reduced to such lesser
amount as may be required pursuant to the methods of calculation necessary so
that the exemptions provided pursuant to Rule 16b-3 under the Securities
Exchange Act of 1934 as amended (the "Exchange Act") will continue to be
available for transactions involving all current and future grants. In addition,
during the period that any grants remain outstanding under the Plan, the
Committee may make good faith adjustments with respect to the number of shares
of Common Stock attributable to such grants for purposes of calculating the
maximum number of shares of Common Stock available for the granting of future
grants under the Plan, provided that following such adjustments the exemptions
provided pursuant to Rule 16b-3 under the Exchange Act will continue to be
available for transactions involving all current and future grants.

      1.6   Definitions

      The following definitions shall apply to the Plan:

                                      (34)


      (a) "Disability" shall have the meaning provided in the Company's
applicable disability plan or, in the absence of such a definition, when a
Participant becomes totally disabled (as determined by a physician mutually
acceptable to the participant and the Company) before termination of his or her
service on the Board if such total disability continues for more than three (3)
months.

      (b) "Fair Market Value" means the average of the high and low sales prices
of the shares of Common Stock on such date on the principal national securities
exchange or automated quotation system of a registered securities association on
which such shares of Common Stock are listed or admitted to trading. If the
shares of Common Stock on such date are not listed or admitted to trading, the
Fair Market Value shall be the value established by the Board in good faith.

                                   II. OPTIONS

      2.1   Terms and Conditions of Options

      Each Participant who is elected a director on April 25, 2005 and at
subsequent Annual Meetings and who has not received any prior grant under this
or previous plans shall receive an initial grant of an Option to purchase 5,000
shares of Common Stock (the "Initial Option") on his/her date of election as a
director. The Initial Options will vest over three years as described in Section
2.4.

      Each Participant who is elected a director at an annual meeting and is not
receiving an Initial Option grant will receive a 2,500 share option (the "Annual
Option") grant. Under the Plan, the Board of Directors has the authority to
increase or decrease the number of shares of Common Stock which are the subject
of such Annual or Initial Option grants.

      2.2   Nonqualified Stock Options

      The terms of the Options shall, at the time of grant, provide that the
Options will not be treated as incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

      2.3   Option Price

      The option price per share shall be the Fair Market Value of the Common
Stock on the date the Option is granted.

      2.4   Term and Exercise of Options

      (a) The term of an Option shall not exceed ten (10) years from the date of
grant. Except as provided in this Section 2.4, after a Participant ceases to
serve as a Director of the Company, including, without limitation, any voluntary
or involuntary termination of a Participant's service as a director (a
"Termination"), the unexercisable portion of an Option shall immediately
terminate and be null and void, and the unexercised portion of any outstanding
Options held by such Participant shall terminate and be null and void for all
purposes, after thirty (30) days have elapsed from the date of the Termination
unless extended by the Committee, in its sole discretion, within thirty (30)
days from the date of the Termination. Upon a Termination as a result of death
or disability, any outstanding Options may be exercised by the Participant or
the Participant's legal representative within twelve (12) months after such
death or disability. Retirees from the board have the same rights except that
for those who have served at least five years on the board, the exercise rights
for Options they hold are automatically extended to the expiration of the option
term. However, in no event shall the period extend beyond the expiration of the
option term. "Retirement" is defined for the purposes of this Section as the
termination of a Participant's service as a director (i) at the end of his/her
term of office where he/she is not re-elected or (ii) during his/her term of
office, for a reason other than death or disability; provided, in either case,
that the Board of Directors, in its sole discretion, determines that the
Participant is entitled to the benefit of Retirement under this subsection.

                                      (35)


      (b) Initial Options granted April 25, 2006, and later shall have a ten
(10) year term and become exercisable as follows:

      25% - date of grant
      25% - one year after date of grant
      25% - two years after date of grant
      25% - three years after date of grant

      (c) Annual Options shall become exercisable one day after the date of
grant for Annual Options granted on April 25, 2005 or later. In no event,
however, shall an Option be exercised after the expiration of ten (10) years
from the date of grant.

      (d) A Participant, by written notice to the Company, may designate one or
more persons (and from time to time change such designation) including his or
her legal representative, who, by reason of his or her death, shall acquire the
right to exercise all or a portion of the Option. If no designation is made
before the death of the Participant, the Participant's Option may be exercised
by the personal representative of the Participant's estate or by a person who
acquired the right to exercise such Option by will or the laws of descent and
distribution. If the person with exercise rights desires to exercise any portion
of the Option, such person must do so in accordance with the terms and
conditions of this Plan.

      2.5   Notice of Exercise

      When exercisable pursuant to the terms of the Plan and the governing stock
option agreement, an Option shall be exercised by the Participant as to all or
part of the shares subject to the Option by delivering written notice of
exercise to the Company at its principal business office or such other office as
the Company may from time to time direct, (a) specifying the number of shares to
be purchased, (b) accompanied by a check payable to the Company in an amount
equal to the full exercise price of the number of shares being exercised, and
(c) containing such further provisions consistent with the provisions of the
Plan as the Company may from time to time prescribe. No Option may be exercised
after the expiration of the term specified in Section 2.4 hereof.

                                      (36)


      2.6   Limitation of Exercise Periods

      The Committee may limit the time periods within which an Option may be
exercised if a limitation on exercise is deemed necessary in order to effect
compliance with applicable law.


                             III. GENERAL PROVISIONS

      3.1   General Restrictions

      Each grant under the Plan shall be subject to the requirement that if the
Committee shall determine, at any time, that (a) the listing, registration or
qualification of the shares of Common Stock subject or related thereto upon any
securities exchange or under any state or federal law, or (b) the consent or
approval of any government regulatory body, or (c) an agreement by the
Participant with respect to the disposition of shares of Common Stock, is
necessary or desirable as a condition of, or in connection with, the granting or
the issuance or purchase of shares of Common Stock thereunder, such grant may
not be consummated in whole or in part unless such listing, registration,
qualification, consent, approval or agreement shall have been effected or
obtained free of any conditions not acceptable to the Committee.

      3.2   Adjustments for Changes in Capitalization

      In the event of a reorganization, recapitalization, stock split, stock
dividend, combination of shares, rights offer, liquidation, dissolution, merger,
consolidation, spin-off or sale of assets, or any other change in or affecting
the corporation structure or capitalization of the Company, the Board shall make
such adjustments as the Committee may recommend, and as the Board in its
discretion may deem appropriate, in the number and kind of shares authorized by
the Plan, in the number, Option price or kind of shares covered by the grants
and in any outstanding grants under the Plan in order to prevent substantial
dilution or enlargement thereof.

      3.3   Amendments

      Without further approval of the shareholders, the Board may discontinue
the Plan at any time and may amend it from time to time in such respect as the
Board may deem advisable including the initial and annual numbers of options
granted, unless shareholder or regulatory approval is required by law or
regulation, and subject to any conditions established by the terms of such
amendment; provided, however, that the Plan may not be amended 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.

                                       (37)


      3.4   Modification, Substitution or Cancellation of Grants

      No rights or obligations under any outstanding Option may be altered or
impaired without the Participant's consent. The Company at its discretion and
with the agreement of the Participant may buy out the Participant's option
rights on Termination (including but not limited to voluntary or involuntary
termination, death, disability and retirement) in return for cancellation of
exercisable grants. Unexercised grants returned to the Company can be regranted
to the Plan.

      3.5   Shares Subject to the Plan

      Shares distributed pursuant to the Plan shall be made available from
authorized but unissued shares or from shares purchased or otherwise acquired by
the Company for use in the Plan, as shall be determined from time to time by the
Committee.

      3.6   Rights of a Shareholder

      Participants under the Plan, unless otherwise provided by the Plan, shall
have no rights as shareholders by reason thereof unless and until certificates
for shares of Common Stock are issued to them.

      3.7   Withholding

      If a Participant is to experience a taxable event in connection with the
receipt of shares of Common Stock pursuant to an Option exercise, the
Participant shall pay the amount equal to the federal, state and local income
taxes and other amounts as may be required by law to be withheld by the Company
prior to the issuance of such shares of Common Stock. If a cash payment is made
in lieu of exercise, taxes will also be withheld as required by law.

      3.8   Nonassignability

      Except as expressly provided in the Plan, no grant shall be transferable
except by will, the laws of descent and distribution or a qualified domestic
relations order ("QDRO") as defined by the Code or Title I of the Employee
Retirement Income Security Act of 1974, as amended, or the rules thereunder.
During the lifetime of the Participant, except as expressly provided in the
Plan, grants under the Plan shall be exercisable only by such Participant or by
the guardian or legal representative of such Participant.

      3.9   Nonuniform Determinations

      Determinations by the Committee under the Plan (including, without
limitation, determinations of the persons to receive grants, the form, amount
and timing of such grants, and the terms and provisions of such grants and the
agreements evidencing the same) need not be uniform and may be made by it
selectively among persons who receive, or are eligible to receive, awards under
the Plan, whether or not such persons are similarly situated.

                                      (38)


      3.10  Effective Date; Duration

      The Plan, as amended, shall become effective as of the date the
shareholders approve the Plan. No grant may be given under the Plan after May
31, 2015, but grants theretofore granted may extend beyond such date.

      3.11  Change in Control

      Notwithstanding anything herein to the contrary, if a Change in Control of
the Company occurs, then all Options shall become fully exercisable as of the
date such Change in Control occurred. For the purposes of the Plan, a Change in
Control of the Company shall be deemed to have occurred upon the earliest of the
following events:

      (a) when the Company acquires actual knowledge that any person (as such
term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the
beneficial owner (as defined in Rule 13d-3 of the Exchange Act) directly or
indirectly, of securities of the Company representing 25% or more of the
combined voting power of the Company's then-outstanding securities;

      (b) upon the first purchase of Common Stock pursuant to a tender or
exchange offer (other than a tender or exchange offer made by the Company);

      (c) upon the approval by the Company's shareholders of (i) a merger or
consolidation of the Company with or into another corporation (other than a
merger or consolidation in which the Company is the surviving corporation and
which does not result in any capital reorganization or reclassification or other
change in the Company's then outstanding shares of Common Stock), (ii) a sale or
disposition of all or substantially all of the Company's assets or (iii) a plan
of liquidation or dissolution of the Company; or

      (d) if the Board of Directors or any designated committee determines in
its sole discretion that any person (as such term is used in Sections 13(d) and
14(d) of the Exchange Act), other than a person who exercised a controlling
influence as of the effective date of the Plan, directly or indirectly exercises
a controlling influence over the management or policies of the Company.

      3.12  Governing Law

      The Plan and all actions taken thereunder shall be governed by and
construed in accordance with the laws of the State of Connecticut.

                                      (39)
