Exhibit 10.21

HARDINGE INC.
  
Executive Supplemental Pension Plan
  
(As Amended December 13, 2004)

        The Supplemental Pension Plan (the "Plan"), effective as of January 1,
1993, is designed to provide a benefit which, when added to other retirement
income, will ensure the payment of a competitive level of retirement income in
order to attract, retain and motivate selected executives of Hardinge Inc.
("Hardinge"). The Compensation Committee of the Board of Directors of Hardinge
shall serve as the Supplemental Pension Plan Committee ("Committee") and shall
have the authority to administer the Plan. The Committee's decision in any
matter involving the interpretation and application of the Plan shall be final
and binding. All terms used in the Plan and not otherwise defined herein shall
have the same meaning as such terms are used in the Hardinge Inc. Pension Plan
("Pension Plan").

        1.    Eligibility.    From time to time Hardinge's Board of Directors
may select executives as Participants in the Plan as of dates designated by the
Committee. In no event shall a Participant or a Participant's Beneficiary be
eligible for, or receive a benefit under the Plan unless and until the
Participant is entitled to a benefit under the Pension Plan.

        2.    Benefits.    Unless otherwise specified by written agreement
between Hardinge and the Participant, the benefits which Hardinge shall pay to a
Participant or his Beneficiary under the Plan shall equal the excess, if any, of
(a) over (b) where:

        (a)   is the benefit which would have been paid to the Participant or to
his Beneficiary under the terms of the Pension Plan as in effect on the date of
the Participant's termination of employment, computed, however, as if:

(i)the Pension Plan benefit formula as presently set forth in Section 4.1
thereof, were adjusted to provide a Normal Pension each year for life equal to
11/4% of the Participant's Final Average Annual Compensation times the number of
years and fractions thereof of Credited Service to the date of termination of
employment. For the purposes hereof, Annual Compensation shall mean base salary
plus cash bonuses received for services rendered in a calendar year whether or
not actually received in that year (provided, however, the amount of cash
bonuses in any year for the purposes hereof shall be limited to 50% of the base
salary for said year) and Final Average Annual Compensation shall mean the
average of the Participant's highest Annual Compensation received in any three
of the five full calendar years immediately preceding the date of termination of
employment.

Minimum Benefit.    In no case shall the benefit earned hereunder be less than
the benefit computed in accordance with the terms of the Pension Plan, provided
however, that in computing this minimum benefit there shall be substituted with
respect to the Pension Plan's past service benefit formula 11/2% for each year
of Credited Service in place of the present 11/4% (or such other percentage as
may be in effect from time to time under the Pension Plan), and

(ii)the basic Pension Plan benefit formula and all benefits under the Pension
Plan were administered and payable without regard to the special benefit
limitations as set forth in Section 7.2 of the Pension Plan as amended from time
to time to comply with the provisions of Section 415 of the Internal Revenue
Code (as amended to date and as may hereafter be amended) limiting benefits
payable under tax-qualified retirement plans, and

--------------------------------------------------------------------------------

        (b)   is the benefit which is payable to the Participant or to his
Beneficiary under the terms of the Pension Plan as in effect on the date of the
Participant's termination of employment, or if later, the date benefits commence
to the Participant or his Beneficiary, as the case may be.

Payments of benefits under the Plan shall be coincident in time and form with
the payment of the pension benefits made to, or on behalf of, a Participant or
his Beneficiary under the Pension Plan, unless otherwise determined by the
Committee, provided however that the provisions of Section 4.8 of the Pension
Plan shall not be applicable to this Plan. Subject to the right of Hardinge to
discontinue the Plan, in whole or in part and as to any one or all of the
Participants, a Participant shall have a nonforfeitable interest in benefits
payable under the Plan to the same extent as benefits are vested under
Article IV of the Pension Plan.

        The benefits provided under the Plan shall not apply to a Participant's
service following his sixty-fifth (65th) birthday. If a Participant continues
employment with Hardinge after reaching age sixty-five (65), no further benefits
of any kind shall accrue under the Plan for service after said date and benefits
under the Plan shall be payable only upon the Participant's subsequent
termination of employment. In the event of such continued employment, the
benefit payable under the Plan shall be frozen on the Participant's sixty-fifth
(65th) birthday, and thereafter reduced by benefits earned under the Pension
Plan following attainment of age sixty-five (65).

        To the maximum extent permitted by law, no benefit under the Plan shall
be assignable or subject to any manner of alienation, sale, transfer, claims of
creditors, pledge, attachment or encumbrances of any kind.

        3.    Indemnification.    To the full extent authorized or permitted by
law, Hardinge shall indemnify any person who brings an action or proceeding,
whether civil or criminal, or is made, or threatened to be made, a party to an
action or proceeding, whether civil or criminal, by reason of the fact that he,
his testator or intestate, is or shall be entitled to benefits under this Plan
and Hardinge has failed to make payments hereunder when due or has otherwise
failed to follow the terms of the Plan or such person has reasonable cause to
believe Hardinge shall or intends to so fail to perform its future obligations
hereunder arising within a reasonable time thereof, or with respect to any other
matter directly or indirectly related to this Plan, unless a judgment or other
final adjudication adverse to such person establishes that Hardinge was or is
legally entitled to fail to so perform its obligations hereunder. Without
limitation of the foregoing, such indemnification shall include indemnification
against all costs of whatsoever nature or kind, including attorneys' fees and
costs of investigation or defense, incurred by any such person with respect to
any such action or proceeding and any appeal therein, and which judgments,
fines, amounts and expenses have not been recouped by him in any other manner.
All expenses incurred by a person in connection with an actual or threatened
action or proceeding with respect to which such person is or may be entitled to
indemnification under this Section, shall, in the absence of a final
adjudication adverse to such person as described above, be promptly paid by
Hardinge to him, upon receipt of an undertaking by him to repay the portion of
such advances, if any, to which he may finally be determined not to be entitled.
This Section may not without the consent of such a person be amended or changed
in any manner adverse to such person. The indemnification provided by this
Section shall not be deemed exclusive of any other rights to which a person may
be entitled other than pursuant to this Section.

        4.    Miscellaneous.    Hardinge expects to continue the Plan
indefinitely but reserves the right at any time and from time to time by action
of the Committee to amend, suspend or discontinue it, in whole or in part and
with respect to any one or all of the Participants and beneficiaries hereunder,
if in the Committee's sole discretion and judgment, such a change is deemed
necessary or desirable. However, no such amendment, suspension or termination
shall affect a Participant's or beneficiary's right to receive the benefits
accrued in accordance with this Plan as in effect immediately prior to such
amendment, suspension or termination. Neither the adoption of the Plan by
Hardinge nor any action of

--------------------------------------------------------------------------------

Hardinge or the Committee under the Plan shall be held or construed to confer
upon any person any legal right to be continued as an employee of Hardinge. All
Participants shall be subject to discharge to the same extent as they would have
been if the Plan had never been adopted. The Plan shall be binding on Hardinge's
successors and assigns and is established under and shall be construed according
to the laws of the State of New York.

        IN WITNESS WHEREOF, Hardinge has caused this instrument to be executed
by its officers thereunto duly authorized and its corporate seal to be hereunto
affixed as of this 13th day of December, 2004.
