     All documents filed by the Registrant pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of
1934, as amended (the "Securities Exchange Act"), after the date
of this Registration Statement and prior to the filing of a post-
effective amendment which indicates that all securities offered
have been sold or which deregisters all securities then remaining
unsold, shall be deemed to be incorporated by reference in this
Registration Statement and to be a part hereof from the date of
filing such documents.  Any statement contained in a document
incorporated or deemed to be incorporated by reference herein
shall be deemed to be modified or superseded for purposes of this
Registration Statement to the extent that a statement contained
herein or in any other subsequently filed document which also is
or is deemed to be incorporated by reference herein modifies or
supersedes such statement.  Any such statement so modified or
superseded shall not be deemed, except as so modified or

Item 4.  Description of Securities.
         Not applicable.

Item 5.  Interests of Named Experts and Counsel.
         Not applicable.

Item 6.  Indemnification of Directors and Officers.
         With respect to indemnification of directors and officers,
Section 145 of the Delaware General Corporation Law (the "DGCL")
provides that a corporation shall have the power to indemnify any
person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the
corporation) by reason of the fact that the person is or was a
director, officer, employee or agent of the corporation, or is or
was serving at the request of the corporation as a director,
officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding, if the person
acted in good faith and in a manner the person reasonably
believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's
conduct was unlawful.  Under this provision of the DGCL, the
termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the
person did not act in good faith and in a manner which the person
reasonably believed to be in or not opposed to the best interests
of the corporation, and with respect to any criminal action or
proceeding, had reasonable cause to believe that the person's
conduct was unlawful.





5

     Furthermore, the DGCL provides that a corporation shall have
the power to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that the
person is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually
and reasonably incurred by the person in connection with the
defense or settlement of such action or suit if the person acted
in good faith and in a manner the person reasonably believed to
be in or not opposed to the best interests of the corporation,
except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been
adjudged to be liable to the corporation unless and only to the
extent that the Court of Chancery or the court in which such
action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

     The Registrant's Certificate of Incorporation (the
"Certificate of Incorporation") provides for limitation of the
liability of directors to the Registrant and its stockholders and
for indemnification of directors, officers, employees and agents
of the Registrant, respectively, to the maximum extent permitted
by the DGCL and provides that such rights of indemnification
shall be in addition to any rights to which any such director,
officer, employee or agent may otherwise be entitled to under any
other statute, the Certificate of Incorporation or by virtue of
any agreement or vote of the stockholders or disinterested
directors or otherwise both as to action in his or her official
capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such
person.

     The Certificate of Incorporation further provides that
directors are not liable to the Registrant or its stockholders
for monetary damages for breaches of fiduciary duty as a
director, except for liability (a) for any breach of the
director's duty of loyalty to the Registrant or its stockholders,
(b) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law, (c) for
dividend payments or stock repurchases in violation of Delaware
law, or (d) for any transaction from which the director derived
any improper personal benefit.







6
     Insofar as indemnification for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act"), may be
permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         Not applicable

Item 8.  Exhibits.

Item 9.  Undertakings.

     (a)  The undersigned Registrant hereby undertakes (subject
to the provision contained in Item 512(a) of Regulation S-K):

     (1)  to file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration
Statement:

     (i)  to include any prospectus required by Section 10(a)(3)
of the Securities Act of 1933, as amended;

     (ii)  to reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement
(or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change
in the information set forth in this Registration Statement.
Notwithstanding the foregoing, any increase or decrease in volume
of securities offered (if the total dollar value of securities
offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum
offering range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate,
the changes in volume and price represent no more than 20 percent
change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective
Registration Statement; and

     (iii)  to include any material information with respect to
the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information
in this Registration Statement.

     (2)  That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective
amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial
bona fide offering thereof.

     (3)  To remove from registration by means of a post-
effective amendment any of the securities being registered which
remain unsold at the termination of the offering.

     (b)  The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Securities Exchange Act of
1934 that is incorporated by reference in this Registration
Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial
bona fide offering thereof.






8
     (c)  Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the Registrant pursuant to
the provisions described under Item 6 above, or otherwise, the
Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore,
unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question
whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by
the final adjudication of such issue.

   OFFERED OR TO BE OFFERED BY CERTAIN SELLING STOCKHOLDERS OF
    GRAHAM CORPORATION FOLLOWING THEIR ACQUISITION UNDER THE
                     2000 GRAHAM CORPORATION
           INCENTIVE PLAN TO INCREASE SHAREHOLDER VALUE


     Certain of our directors and officers, all of whom are named
in this prospectus as selling stockholders, from time to time may
offer up to 150,000 shares of Graham Common Stock which they have
acquired under the 2000 Graham Corporation Incentive Plan to
Increase Shareholder Value ("Plan").  The shares may be sold
directly by the holder to purchasers or may be given by the
holder to donees, such as members of the holder's family or
charitable organizations, and then sold by the donee to the
purchasers. Sales may occur through the facilities of the
American Stock Exchange, on which the shares are listed, or may
occur privately, at prevailing market prices or at negotiated
prices.  Sales may be made through brokers or to dealers, who are
expected to receive customary commissions or discounts.  We will
not receive any of the proceeds from such sales.  We will bear
the costs relating to the registration of the shares being
offered by this prospectus, other than commissions or discounts
to brokers or dealers.

     The selling stockholders, as well as any participating
brokers and dealers, may be deemed to be "underwriters" within
the meaning of the Securities Act of 1933, as amended.  If this
occurs, any profit on the sale of shares by those selling
stockholders and any commissions or discounts received by those
brokers or dealers may be deemed to be underwriting compensation
under the Securities Act.

     Our common stock is traded on the American Stock Exchange
under the symbol "GHM".  On March 29, 2004, the closing price of
our common stock on the American Stock Exchange was $10.91 per
share.

                          RISK FACTORS

     Our customers are concentrated in cyclical industries.

     Historically, almost all of our revenues have been derived
from sales to companies in the chemical, petrochemical, petroleum
refining, and electrical power generating industries. Companies
in these industries have historically experienced cyclical
periods of contraction and expansion of their plants and
facilities.  Currently, in the United States, these industries
are experiencing a protracted cycle of little expansion of
existing facilities.  For example, no new major petroleum
refining facilities have been constructed in the United States
for over 20 years.  As a result, demand for our products has
increasingly come from the construction of new facilities outside
the United States and from the upgrading of existing facilities
within the United States.  While we believe that over the long
run demand for our products will increase, we may not be
successful in our efforts to continue to derive a greater portion
of revenues from outside the United States, or the cyclical
downturn in our customers' industries may continue.  In addition,
future export sales may not provide profit levels consistent with
historical profitability.

     Our financial results may fluctuate.

     Our revenues and operating results can fluctuate
significantly from period to period. Given the relatively high
sale price of our products and variations in profit margins
between our product lines, a limited number of product orders may
account for a substantial portion of our revenues and profits in
any particular period.  As a result of these and other factors,
we could experience significant fluctuations in revenues and
operating results in future periods.

     Our technology may become obsolete.

     We believe that our future success depends, in part, upon
our ability to enhance our existing products as well as develop
and manufacture new products to meet the demands of our
customers.  If we fail to introduce new or enhanced products on a
timely or cost-competitive basis, our business could be seriously
harmed.

     We operate in a competitive marketplace and rely on a small
number of product lines for a substantial portion of our revenue.

     The markets in which we operate are composed of other global
and regional competitors, some of which have greater financial,
engineering, manufacturing or other resources than we do.
Although we believe that we are a leading manufacturer of steam
jet ejectors and round steam surface condensers, we gather a
small percentage of the market share in our other product areas.
We may not be successful in capturing additional market share or
maintaining our current market share.  A decline in our sales of
steam jet ejectors could seriously harm our business.

     The price of our common stock may decline due to this
offering.
14
     Public trading in our common stock is characterized by a
small trading volume.  The addition of the shares offered hereby
may create an excess of the supply of shares for sale over the
demand for shares to be purchased, which may in turn lead to a
decline in the price at which our common stock trades.

     Our success depends upon retaining the services of our
executive management team.

     We are highly dependent on our executive management team.
We expect that our continued success will largely depend upon the
efforts and abilities of members of our executive management
team.  The loss of the services of any key executive for any
reason could have a material adverse effect upon us.  Our success
also depends upon our ability to identify, develop, and retain
employees.  The loss of some of our key employees could seriously
harm our business.

     Our corporate structure may discourage takeover attempts.

     Our certificate of incorporation and by-laws contain certain
provisions that may discourage potential takeover attempts that
are not negotiated with our board of directors.  As a result,
these provisions may have the effect of precluding takeover
attempts that you might otherwise deem to be in your best
interests, or pursuant to which you might otherwise receive a
substantial premium for your shares over market price.  These
provisions may also make it more difficult for our stockholders
to acquire majority representation on our board of directors.
These provisions provide, among other things, that:

     (1)  our board of directors is divided into three classes with
          staggered terms, which means that only a portion of our board of
          directors may be elected at each annual meeting;

     (2)  a supermajority vote of our stockholders must be obtained in
          order to consummate certain business combinations not approved in
          advance by our board of directors, such as our merger or
          dissolution;

     (3)  our board of directors may issue additional shares of common
          stock or shares of preferred stock without the approval of our
          stockholders (including the issuance of such shares in connection
          with our stockholder rights plan);

     (4)  cumulative voting, whereby a stockholder may cast as many
          votes for directors as he or she has shares of stock multiplied
          by the number of directors to be elected, is not permitted in
          connection with the election of our directors, which may have the
          effect of preventing the representation of minority stockholders
          on our board of directors; and

     (5)  only the chairman of our board, the president, or the
          secretary at the request of at least seventy-five percent of our
          directors can call a special meeting of our stockholders.

     Our executive management team may have the ability to
dominate stockholder voting.

15
     Our directors and executive officers currently hold or
control the voting of approximately 22.6% of the outstanding
shares of our common stock, either directly or through
participation in employee benefit plans.  Management's potential
voting control could, together with additional stockholder
support, defeat stockholder proposals requiring a supermajority
vote.  As a result, our management team could preclude or render
more difficult a change in control of our company that certain
stockholders may deem to be in their best interest and may also
have the effect of perpetuating our existing management.

     Our remuneration plans and agreements may discourage
takeovers.

     Our employment agreements with certain members of our
management team and our stock option plans may provide for
benefits and cash payments in the event of a change in control.
These provisions may have the effect of increasing the cost of
acquiring the company, which may discourage future takeover
attempts.


                           OUR COMPANY

     We were incorporated in 1983 as a Delaware corporation.  We
are the successor to Graham Manufacturing Co., Inc., which was
incorporated in 1936.  We conduct our business operations in the
United States and the United Kingdom.

     Our products function to produce a vacuum or to condense
steam or otherwise transfer heat, or any combination of these
tasks.  Our condensers and ejectors accomplish this without any
moving parts and, like our vacuum pumps, are available in all
metals as well as in many non-metallic and corrosion resistant
materials.

     Our equipment is used in a wide range of industrial process
applications.  Some of these industrial process applications
include: power generation facilities, including fossil fuel
plants and nuclear plants, as well as cogeneration plants and
geothermal power plants that harness naturally occurring thermal
energy; petroleum refineries; chemical plants; pharmaceutical
plants; plastics plants; fertilizer plants; breweries and
titanium plants; liquefied natural gas production; soap
manufacturing; air conditioning systems; food processing plants
and other process industries.  Among these industrial process
applications, the principal markets for our products are the
chemical, petrochemical, petroleum refining, and electric power
generating industries.

     Our products are sold by a combination of direct company
sales engineers and independent sales representatives located in
over 40 major cities in the United States and abroad.

                         USE OF PROCEEDS

                  The shares will be offered by certain
individuals who acquire them upon exercise of options granted
under the Plan for their personal accounts. The proceeds from
such sales will be used by them for their personal benefit.  We
will not receive any of the proceeds from the sale of such
shares.

                      SELLING STOCKHOLDERS

              The shares offered hereby will be issued to the
selling stockholders upon exercise of options under the 2000
Graham Corporation Incentive Plan to Increase Shareholder Value.
Each selling stockholder is a director or officer of ours, or
both.  With respect to each selling stockholder, the table that
follows below sets forth:

          the name and principal position or positions held with us
          over the past three years;

          the number of shares of common stock beneficially owned
          prior to this offering;

          the number of shares of our common stock offered under this
          prospectus;

          the number of shares of our common stock beneficially owned
          by each selling stockholder following this offering, assuming the
          sale in this offering of all shares acquired by the selling
          stockholder pursuant to the 2000 Graham Corporation Incentive
          Plan to Increase Shareholder Value and registered under the
          registration statement of which this prospectus is a part; and

          the percentage of the total class of shares of our common
          stock (if one percent or more) beneficially owned by each selling
          stockholder following this offering, assuming the sale in this
          offering of all shares acquired by the selling stockholder
          pursuant to the 2000 Graham Corporation Incentive Plan to
          Increase Shareholder Value and registered under the registration
          statement of which this prospectus is a part.

     Beneficial ownership is determined in accordance with the
rules of the Securities and Exchange Commission.  We have
calculated the percentage of our common stock beneficially owned
by each selling stockholder based upon the 1,910,450 shares of
our common stock outstanding after this offering.

                      PLAN OF DISTRIBUTION

     Shares covered by this prospectus may be offered for sale on
the American Stock Exchange where they are listed. They may be
offered from time to time in private transactions.  The Company
will not receive any proceeds from such sales.

     Each sale may be made either at the market price prevailing
at the time of sale or at a negotiated price.  Sales may be made
through brokers or to dealers, and those brokers or dealers may
receive compensation in the form of commissions or discounts not
exceeding those customary in similar transactions.  All expenses
of registration incurred in connection with this offering are
being borne by us, but all brokerage commissions and other
expenses incurred by a selling stockholder will be borne by that
selling stockholder.

     The selling stockholders and any dealer acting in connection
with the offering or any broker executing a sell order on behalf
of a selling stockholder may be deemed to be "underwriters"
within the meaning of the Securities Act, in which event any
profit on the sale of shares by a selling stockholder and any
commissions or discounts received by any broker or dealer may be
deemed to be underwriting compensation under the Securities Act.
In addition, any broker or dealer may be required to deliver a
copy of this prospectus to any person who purchases any of the
shares from or through the broker or dealer.

     In order to comply with the securities laws of certain
states, if applicable, the shares will be sold only through
registered or licensed brokers or dealers.  Sales of common stock
must also be made by the selling stockholders in compliance with
all other applicable securities laws and regulations.
