          (a) the distinctive designation of, and the number of shares
     comprising, such series, which number may be increased (except where
     otherwise provided by the Board of Directors in creating such series) or

     dividends shall bear to the dividends payable on any other class or classes

     optional, or other special rights of the shares of such series, and
     qualifications, limitations, or restrictions thereof, to the full extent
     now or



                                       -4-


     hereafter permitted by law and not inconsistent with the provisions hereof.

     All shares of any one series of preferred Stock shall be identical in all
respects except as to the dates from which dividends thereon shall be
cumulative. All series of the Preferred Stock shall rank equally and be
identical in all respects except as otherwise provided in the resolution or
resolutions providing for the issue of any series of Preferred Stock.

     Whenever dividends upon the Preferred Stock at the time outstanding, to the
extent of the preference to which such stock is entitled, shall have been paid
in full or declared and set apart for payment for all past dividend periods, and
after the provisions for any sinking or purchase fund or funds for any series of
Preferred Stock shall have been complied with, the Board of Directors may
declare and pay dividends on the Common Stock, payable in cash, stock, or
otherwise, and the holders of shares of Preferred Stock shall not be entitled to
share therein, subject to the provisions of the resolution or resolutions
creating any series of Preferred stock.

entitled as provided in the resolution or resolutions creating any series
thereof, shall be divided and distributed among the

holders of the Common Stock ratably, except as may otherwise be provided in any
such resolution or resolutions. Neither the merger or consolidation of the
Corporation with another corporation nor the sale or lease of all or
substantially all the assets of the Corporation shall be deemed to be a
liquidation, dissolution, or winding up of the Corporation or a distribution of
its assets.

     Except as otherwise required by law or provided by a resolution or
resolutions of the Board of Directors creating any series of Preferred Stock,
the holders of Common Stock shall have the exclusive power to vote and shall
have one vote in respect of each share of such stock held and the holders of
Preferred Stock shall have no voting power whatsoever. Except as otherwise
provided in such a resolution or resolutions, the authorized shares of any class
or classes may be increased or decreased by the affirmative vote of the holders
of a majority of the outstanding shares of stock of the Corporation entitled to
vote.

     whether any corporation, person or other entity owns 5% or more of the
     shares of the Corporation entitled to vote, or is an "affiliate" or an
     "associate" (as defined below) of another, (ii) whether any proposed sale,
     lease, exchange, or other disposition of part of the assets of the
     Corporation involves substantially all of the assets of the Corporation,

               that may be issuable by the Corporation pursuant to any
               agreement, or upon the exercise of conversion rights, warrants,

         CERTIFICATE OF DESIGNATIONS, PREFERENCES AND RIGHTS OF SERIES A
           JUNIOR PARTICIPATING PREFERRED STOCK OF GRAHAM CORPORATION

     Pursuant to Section 151 of the General Corporation Law of the State of
Delaware

     We, Alvaro Cadena, and Cornelius S. Van Rees, being the President and Chief
Executive Officer and the Secretary, respectively, of GRAHAM CORPORATION, a
corporation organized and existing under the General Corporation Law of the
State of Delaware (the "CORPORATION"), in accordance with the provisions of
Sections 103 and 151 thereof, DO HEREBY CERTIFY:

     That, pursuant to the authority conferred upon the board of directors of
the Corporation (the "BOARD") by the Certificate of Incorporation of the
Corporation, the Board at a meeting duly called and held on July 27, 2000, at
which a quorum was present and acting throughout, duly adopted the following
resolution creating a series of sixty thousand (60,000) shares of Preferred
Stock, par value ONE DOLLAR ($1.00) per share, designated "Series A Junior
Participating Preferred Stock":

          RESOLVED, that, pursuant to the authority vested in the Board in
     accordance with the provisions of its Certificate of Incorporation, a
     series of preferred stock of the Corporation to be designated "Series A
     Junior Participating Preferred Stock," par value ONE DOLLAR ($1.00) per
     share (the "PREFERRED STOCK"), be, and it hereby is, created, the
     designations and amount thereof and the voting powers, preferences and
     relative, participating, optional and other special rights of the shares of
     such series, and the qualifications, limitations and restrictions thereof,
     to be as follows:

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

     SECTION 1. Designation and Amount. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock," par value ONE
DOLLAR ($1.00) per share, and the number of shares constituting such series
shall be sixty thousand (60,000). Such number of shares may be increased or
decreased by resolution of the Board; provided, that no decrease shall reduce
the number of shares of Series A Junior Participating Preferred Stock to a
number less than the number of shares then outstanding plus the number of shares
reserved for issuance upon the exercise of outstanding options, rights or
warrants or upon the conversion of any outstanding securities issued by the
Corporation convertible into Series A Junior Participating Preferred Stock.

     SECTION 2. Dividends and Distributions.

     (a) Subject to the rights of the holders of any shares of any series of
preferred stock (or any similar stock) ranking prior and superior to the Series
A Junior Participating Preferred Stock with respect to dividends, the holders of
shares of Series A Junior Participating Preferred Stock, in preference to the
holders of Common Stock, par value TEN CENTS ($0.10) per share (the "COMMON
Stock"), of the Corporation, and of any other junior stock, shall be entitled to
receive, when, as and if declared by the Board out of funds legally available
for the purpose, quarterly dividends payable in cash on the first day of March,
June, September and December in each year



(each such date being referred to herein as a "QUARTERLY DIVIDEND PAYMENT
DATE"), commencing on the first Quarterly Dividend Payment Date after the first
issuance of a share or fraction of a share of Series A Junior Participating
Preferred Stock, in an amount per share (rounded to the nearest cent) equal to
the greater of (a) ONE DOLLAR ($1.00) or (b) subject to the provision for
adjustment hereinafter set forth, one hundred (100) times the aggregate per
share amount of all cash dividends, and one hundred (100) times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions, other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Junior Participating Preferred Stock. In the event the Corporation
shall at any time declare or pay any dividend on the Common Stock payable in
shares of Common Stock, or effect a subdivision or combination or consolidation
of the outstanding shares of Common Stock (by reclassification or otherwise than
by payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Junior Participating Preferred Stock were entitled
immediately prior to such event under clause (b) of the preceding sentence shall
be adjusted by multiplying such amount by a fraction, the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

     (b) The Corporation shall declare a dividend or distribution on the Series
A Junior Participating Preferred Stock as provided in paragraph (a) of this
Section immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock); provided, that
in the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of ONE DOLLAR ($1.00) per
share on the Series A Junior Participating Preferred Stock shall nevertheless be
payable on such subsequent Quarterly Dividend Payment Date.

     (c) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A Junior Participating Preferred Stock from the Quarterly Dividend
Payment Date next preceding the date of issue of such shares, unless the date of
issue of such shares is prior to the record date for the first Quarterly
Dividend Payment Date, in which ease dividends on such shares shall begin to
accrue from the date of issue of such shares, or unless the date of issue is a
Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Junior Participating Preferred
Stock entitled to receive a quarterly dividend and before such Quarterly
Dividend Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but
unpaid dividends shall not bear interest. Dividends paid on the shares of Series
A Junior Participating Preferred Stock in an amount less than the total amount
of such dividends at the time accrued and payable on such shares shall be
allocated pro rata on a share-by-share basis among all such shares at the time
outstanding. The Board may fix a record date for the determination of holders of
shares of Series A Junior Participating Preferred Stock entitled to receive
payment of a dividend or distribution declared thereon, which record date shall
be not more than sixty (60) days prior to the date fixed for the payment
thereof.


                                       2



     SECTION 3. Voting Rights. The holders of shares of Series A Junior
Participating Preferred Stock shall have the following voting rights:

     (a) Subject to the provision for adjustment hereinafter set forth, each
share of Series A Junior Participating Preferred Stock shall entitle the holder
thereof to one hundred (100) votes on all matters submitted to a vote of the
stockholders of the Corporation. In the event the Corporation shall at any time
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the number of votes per share
to which holders of shares of Series A Junior Participating Preferred Stock were
entitled immediately prior to such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     (b) Except as otherwise provided herein, in any other resolution creating a
series of preferred stock or any similar stock, in any amendment to the
Certificate of Incorporation of the Corporation or bylaw, the holders of shares
of Series A Junior Participating Preferred Stock and the holders of shares of
Common Stock and any other capital stock of the Corporation having general
voting rights shall vote together as one class on all matters submitted to a
vote of stockholders of the Corporation.

     (c) Except as set forth herein, or as otherwise provided by law, holders of
Series A Junior Participating Preferred Stock shall have no special voting
rights and their consent shall not be required (except to the extent they are
entitled to vote with holders of Common Stock as set forth herein) for taking
any corporate action.

     SECTION 4. Certain Restrictions.

     (a) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Junior Participating Preferred Stock as provided in
Section 2 are in arrears, thereafter and until all accrued and unpaid dividends
and distributions, whether or not declared, on shares of Series A Junior
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not:

          (i) declare or pay dividends, or make any other distributions, on any
shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock;

          (ii) declare or pay dividends, or make any other distributions, on any
shares of stock ranking on a parity (either as to dividends or upon liquidation,
dissolution or winding up) with the Series A Junior Participating Preferred
Stock, except dividends paid ratably on the Series A Junior Participating
Preferred Stock and all such parity stock on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such
shares are then entitled;


                                       3



          (iii) redeem or purchase or otherwise acquire for consideration shares
of any stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock,
provided that the Corporation may at any time redeem, purchase or otherwise
acquire shares of any such junior stock in exchange for shares of any stock of
the Corporation ranking junior (either as to dividends or upon dissolution,
liquidation or winding up) to the Series A Junior Participating Preferred Stock;
or

          (iv) redeem or purchase or otherwise acquire for consideration any
shares of Series A Junior Participating Preferred Stock, or any shares of stock
ranking on a parity with the Series A Junior Participating Preferred Stock,
except in accordance with a purchase offer made in writing or by publication (as
determined by the Board) to all holders of such shares upon such terms as the
Board, after consideration of the respective annual dividend rates and other
relative rights and preferences of the respective series and classes, shall
determine in good faith will result in fair and equitable treatment among the
respective series or classes.

     (b) The Corporation shall not permit any subsidiary of the Corporation to
purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     SECTION 5. Reacquired Shares. Any shares of Series A Junior Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of preferred stock and may be reissued as part of a new series of
preferred stock subject to the conditions and restrictions on issuance set forth
herein, in a resolution of the Board, in the Certificate of Incorporation of the
Corporation, or in any other Certificate of Amendment creating a series of
preferred stock or any similar stock or as otherwise required by law.

     SECTION 6. Liquidation, Dissolution or Winding Up. Upon any liquidation,
dissolution or winding up of the Corporation, no distribution shall be made (a)
to the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Junior Participating
Preferred Stock unless, prior thereto, the holders of shares of Series A Junior
Participating Preferred Stock shall have received the greater of (i) ONE HUNDRED
DOLLARS ($100.00) per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment, or (ii) an aggregate amount per share, subject to the provision
for adjustment hereinafter set forth, equal to one hundred (100) times the
aggregate amount to be distributed per share to holders of shares of Common
Stock, or (b) to the holders of shares of stock ranking on a parity (either as
to dividends or upon liquidation, dissolution or winding up) with the Series A
Junior Participating Preferred Stock, except distributions made ratably on the
Series A Junior Participating Preferred Stock and all such parity stock in
proportion to the total amounts to which the holders of all such shares are
entitled upon such liquidation, dissolution or winding up. In the event the
Corporation shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number


                                        4



of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series A Junior Participating Preferred Stock were entitled
immediately prior to such event under the proviso in clause (a) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

     SECTION 7. Consolidation, Merger, Etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed into an amount per share, subject to the
provision for adjustment hereinafter set forth, equal to one hundred (100) times
the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged. In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Series A
Junior Participating Preferred Stock shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     SECTION 8. No Redemption. The shares of Series A Junior Participating
Preferred Stock shall not be redeemable, except as otherwise provided herein.

     SECTION 9. Rank. The Series A Junior Participating Preferred Stock shall
rank, with respect to the payment of dividends and the distribution of assets,
junior to all other series of the Corporation's preferred stock.

     SECTION 10. Amendment. At any time that any shares of Series A Preferred
Stock are outstanding, the Certificate of Incorporation of the Corporation shall
not be amended in any manner, nor shall the Board take any action, which would
materially alter or change the powers, preferences or special rights of the
Series A Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least three-fourths (3/4) of
the outstanding shares of Series A Junior Participating Preferred Stock, voting
together as a single class.

     SECTION 11. Fractional Shares. Series A Junior Participating Preferred
Stock may be issued in fractions of a share, which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Junior Participating Preferred Stock.
