should be read in conjunction with, the more detailed information and financial
statements and notes thereto appearing elsewhere, or incorporated by reference,
in this prospectus supplement and the accompanying prospectus. Before you decide

                                   MOOG INC.

     We are a leading worldwide designer and manufacturer of high performance,
precision motion controls for aerospace and industrial markets. Our products
include military and commercial aircraft flight controls, satellite positioning
controls, and controls for steering tactical missiles, strategic missiles and
space launch vehicles. Industrial applications include injection molding
machines and power-generating turbines. Our global base of military and
commercial aerospace customers includes large original equipment manufacturers
such as The Boeing Company, Lockheed Martin Corporation, Honeywell International
Inc. and Raytheon Company, and the U.S. and foreign governments. We also serve a
diverse base of industrial machine manufacturers. We have operations in 21
countries and, in our fiscal year ended September 28, 2002, sales from our
foreign operations were 27% of total sales. We design and manufacture our
control products and systems within three operating groups: aircraft controls;
space controls; and industrial controls. In fiscal 2002, sales in our aircraft
controls, space controls and industrial controls segments were 50%, 15% and 35%,
respectively, of our total sales.

     We believe we have an excellent reputation in the industries we serve based
on our strong engineering and design capabilities and product reliability. We
have close relationships with our customers which allow us to effectively
evaluate their precision control requirements and identify new business
opportunities. Our products and systems, known as servovalves and
servoactuators, control the position, velocity or force of moving objects with
accuracy that can be measured in millionths of an inch. Not only are these
devices extremely accurate, they also respond to commands in as little as
thousandths of a second and as frequently as one hundred times a second. We
manufacture our products in various U.S., European and Asian facilities which
are supplemented by low cost facilities in India and the Philippines.

     Since our founding in 1951, our focus has been to design solutions to our
customers' complex motion control requirements. The technology behind our
products originated from our involvement on various missile programs and NASA
space missions in the 1950's and 1960's, eventually adapting our technologies to
applications in aircraft and industrial controls. We believe we are a market
share leader in supplying OEM flight control actuation systems for military and
commercial aircraft, steering controls for launch vehicles and propellant
controls for satellites. Our products have been used in almost every U.S.
military aircraft and numerous foreign military aircraft, with an installed base
of products on the F-15 Eagle, the F-16 Falcon, the F/A-18 C/D Hornet, the
UH/SH-60 Blackhawk and Seahawk helicopters and other programs. We also supply
controls for newer military aircraft programs such as the F-35 Joint Strike
Fighter, the F/A-18 E/F Super Hornet, the V-22 Osprey tiltrotor, and the RAH-66
Comanche helicopter. We supply steering controls for a number of strategic and
tactical missile programs, for NASA's Space Shuttle, for many makes of
geosynchronous satellites currently produced, for the U.S. government's national
missile defense strategic initiative, and for the Delta IV and Atlas Evolved
Expendable Launch Vehicle programs. We supply flight controls to the major
commercial aircraft manufacturers, Boeing and Airbus Industrie. We also believe
we are the leading producer of servovalves for global industrial applications.

     The markets we serve provide substantial opportunity for aftermarket sales.
Aftermarket sales are sales of spare and replacement parts along with repair and
overhaul services. In fiscal 2002, aftermarket sales were 23% of our total
sales. The high technological content of our products and our reputation for
reliability encourages customers and end-users to use our routine repair and
maintenance services.

            THE PROPOSED ACQUISITION OF THE POLY-SCIENTIFIC DIVISION

     On August 14, 2003, we signed an agreement to acquire the assets of the
Poly-Scientific division of Litton Systems, Inc., a wholly owned subsidiary of
Northrop Grumman Corporation. The following description of the business of the
Poly-Scientific division is based upon information, which we believe to be
accurate, obtained by us in connection with our evaluation of the acquisition of
the Poly-Scientific division.

     The Poly-Scientific division designs and manufactures electrical and
fiber-optic slip rings, brushless D.C. motors and electromechanical actuators.
Poly-Scientific is a world leader in the manufacture of slip rings. Slip rings
are electromechanical devices that allow the transmission of electrical power
and data across a rotating joint. Slip rings are utilized in a variety of
applications including industrial and medical equipment, aircraft, spacecraft,
military ground vehicles, ships, instrumentation and radar platforms. Poly-
Scientific had annual sales in 2002 of approximately $133 million. Of these
sales, slip rings represent approximately 42%, brushless motors approximately
39% and electromechanical actuators and other products, including optical
switches and optical products, approximately 19%. In 2002, approximately 46% of
sales were to military customers, 20% to commercial aviation and space
customers, 16% to medical customers, 16% to industrial customers and 2% to
telecommunication customers. Poly-Scientific's largest customers by revenues are
Respironics Corporation, Lockheed Martin Corporation, the U.S. government and
Raytheon Corporation.

     Poly-Scientific is headquartered in Blacksburg, Virginia and has
manufacturing facilities in Blacksburg (two locations aggregating approximately
160,000 square feet), Murphy, North Carolina (two locations aggregating
approximately 105,000 square feet) and Springfield, Pennsylvania (one location,
approximately 77,000 square feet). Poly-Scientific employs approximately 1,000
persons.

     Under the acquisition agreement, we will acquire all of the assets of the
Poly-Scientific division for an aggregate purchase price of $158 million in cash
plus the assumption of current operating liabilities incurred in the ordinary
course, which are expected to be approximately $11 million at closing, and
subject to post-closing adjustments for changes in working capital prior to
closing. The closing of the transaction is subject to customary conditions,
including clearance under the Hart-Scott-Rodino Antitrust Improvements Act, and
is expected to occur on September 29, 2003. A copy of the acquisition agreement
is attached as Exhibit 2.1 to our Current Report on Form 8-K filed with the SEC
on September 4, 2003 and incorporated by reference into this prospectus
supplement and the accompanying prospectus.

     As of August 31, 2003, we had approximately $110 million of borrowing
capacity available under our revolving bank credit facility. We have obtained a
commitment from HSBC Bank USA, Societe Generale and Manufacturers and Traders
Trust Company, as lenders, for a new eighteen-month unsecured term loan facility
in a principal amount of up to $80 million. We expect to finance the acquisition
of the Poly-Scientific division with the net proceeds of this offering, together
with additional borrowings under our existing revolving credit facility or
borrowings under our new eighteen-month loan facility, or a combination thereof.
Our ability to finance the acquisition with borrowings under our existing
revolving credit facility or our committed new facility is subject to the
satisfaction of conditions precedent and, in the case of the new facility, the
execution of definitive agreements for the facility.

     The following are selected summary balance sheet and income statement items
derived from the unaudited financial statements of the Poly-Scientific division
for the twelve month period ended December 31, 2002 and the six month period
ended June 30, 2003, which were provided to us by the seller. Sales of the
Poly-Scientific division for the fiscal year ended December 31, 2002 and the six
months ended June 30, 2003 were $132.6 million and $67.1 million, respectively.
Earnings before tax of the Poly-Scientific division for those periods were $16.2
million and $9.0 million, respectively. As of June 30, 2003, total assets of the
Poly-Scientific division were $50.0 million and total liabilities of the
Poly-Scientific division, consisting entirely of current liabilities, were $11.0
million. This historical selected summary information of the Poly-Scientific
division is unaudited and is not necessarily indicative of results to be
expected in the future.

                                       S-2


     Information regarding the expected impact of the acquisition of the
Poly-Scientific division and the effect of this offering on our forecasted
financial performance is set forth below. Assuming the closing of the
acquisition of the Poly-Scientific division occurs on September 29, 2003, we
forecast our net sales for fiscal 2004 to be between $920 million and $940
million, with approximately $465 million expected for sales in aircraft
controls, approximately $112 million expected for sales in space controls and
between approximately $343 million and $363 million expected for sales in
industrial controls. We forecast net income for fiscal 2004 of between $53
million and $57 million and diluted earnings per share for fiscal 2004 of
between $3.10 and $3.30. This forecast of net income and diluted earnings per
share reflects our preliminary estimates of expense associated with the
amortization of intangible assets acquired in the acquisition of the
Poly-Scientific division, expense related to fair value purchase accounting
adjustments principally related to inventory, and the impact of the financing of
the acquisition. If actual amounts differ from these preliminary estimates, our
forecast of 2004 diluted earnings per share and our previously forecasted 2004
operating margins may change. These forward-looking statements are also subject
to the special note set forth below.

                                  RISK FACTORS

     In considering whether to purchase the Class A common stock, you should
carefully consider the risks described below, as well as the risk factors
beginning on page 2 of the accompanying prospectus.

OUR PROPOSED ACQUISITION OF THE POLY-SCIENTIFIC DIVISION PRESENTS RISKS AND
UNCERTAINTIES THAT COULD ADVERSELY AFFECT OUR OPERATING RESULTS.

     Our proposed acquisition of the Poly-Scientific division presents several
risks and uncertainties that could adversely affect our operating results,
including the following:

     - we may not consummate the acquisition of the Poly-Scientific division or
       it may be delayed, whether because of a failure to satisfy closing
       conditions under the purchase agreement, the failure to satisfy
       conditions to borrowing under our existing bank credit facility or our
       commitment for a new supplemental eighteen-month loan, or otherwise;

     - the information of the Poly-Scientific division provided by the seller to
       us, including historical unaudited financial information, included or
       incorporated by reference in this prospectus supplement and the
       accompanying prospectus, may be inaccurate or incomplete;

     - the allocation of the purchase price to the Poly-Scientific division
       assets, the amortization of intangible assets resulting from that
       allocation and the impact of fair value purchase accounting adjustments
       may adversely impact our earnings;

     - increased leverage and debt service requirements as a result of the
       incurrence of additional indebtedness to finance the Poly-Scientific
       division acquisition or to operate the division after the acquisition may
       adversely impact our earnings and our financial flexibility; and

     - a write down of the goodwill associated with the acquisition of the
       Poly-Scientific division could adversely affect our earnings and net
       worth and cause us to violate covenants in our credit agreements.

WE MAY BE UNABLE TO INTEGRATE THE POLY-SCIENTIFIC DIVISION SUCCESSFULLY.

     Integrating the Poly-Scientific division may be distracting to our
management and disruptive to our business and the cost of integration may be
significant. We may face challenges in consolidating functions and integrating
procedures, information technology systems, personnel, product lines and
operations in a timely and efficient manner. In addition, we may be unable to
preserve the relationship between Poly-Scientific and its customers, suppliers
and key employees following the acquisition. If we are not successful in
integrating the Poly-Scientific division into our operations, or if the
integration takes longer than anticipated, our operating results could be
adversely affected.

CLAIMS AGAINST US RELATING TO THE ACQUISITION OF THE POLY-SCIENTIFIC DIVISION
MAY NECESSITATE OUR SEEKING INDEMNIFICATION FROM THE SELLER WHICH THE SELLER MAY
NOT PROVIDE OR WHICH MAY EXCEED THE SELLER'S INDEMNIFICATION OBLIGATIONS.

     There may be liabilities assumed in the acquisition of the Poly-Scientific
division that we did not discover or underestimated in the course of performing
our due diligence investigation. Although the seller will have indemnification
obligations to us under the acquisition agreement, these obligations will be
subject to financial limitations, such as general and per-claim deductibles and
a cap, as well as time limitations. We cannot assure you that our right to
indemnification from the seller will be enforceable, collectible or sufficient
in amount, scope or duration to fully offset the amount of any undiscovered or
underestimated liabilities. Any such liabilities, individually or in the
aggregate, could have a material adverse effect on our operating results.

                                USE OF PROCEEDS

     We estimate that the net proceeds we will receive from our sale of Class A
common stock in this offering will be approximately $62.6 million, or $72.0
million if the underwriters exercise their over allotment option in full, based
on the offering price of $38.00 per share and, after deducting the underwriters'
fees and estimated offering expenses. We expect to use the net proceeds from
this offering to provide a portion of the funds required to pay the purchase
price for our acquisition of the Poly-Scientific division and for general
corporate purposes. In the event we do not complete the Poly-Scientific
acquisition, we expect to use the net proceeds to repay outstanding indebtedness
under our revolving credit facility. Interest on borrowings under the revolving
credit facility, at our election, are at the London Interbank Offered Rate, or
LIBOR, plus a spread, or the prime rate. At June 30, 2003, there were no prime
rate borrowings. The spread on LIBOR-based borrowings is determined by a
leverage ratio, with the spread at June 30, 2003 at 175 basis points. The
weighted average interest rate on borrowings under this facility at June 30,
2003 was 3.04%.

</Table>

     The underwriting agreement provides that the obligations of the
underwriters to purchase the shares of Class A common stock offered hereby are
conditional and may be terminated at their discretion based on the assessment of
the state of the financial markets. The obligations of the underwriters may also
be terminated upon the occurrence of other events specified in the underwriting
agreement. The underwriters are severally committed to purchase all of the
shares of Class A common stock being offered by us if any shares are purchased.

     The underwriters propose to offer the shares of Class A common stock to the
public at the public offering price set forth on the cover of this prospectus
supplement. The underwriters may offer the Class A common stock to securities
dealers at the price to the public less a concession not in excess of $1.197 per
share. Securities dealers may reallow a concession not in excess of $.10 per
share to other dealers. After the shares of common stock are released for sale
to the public, the underwriters may vary the offering price and other selling
terms from time to time.

     We have granted to the underwriters an option, exercisable not later than
30 days after the date of this prospectus supplement, to purchase up to an
aggregate of 262,500 additional shares of Class A common stock at the public
offering price set forth on the cover page of this prospectus supplement less
the underwriting discounts and commissions. The underwriters may exercise this
option only to cover over allotments, if any, made in connection with the sale
of common stock offered hereby. If the over allotment option is exercised in
full, the underwriters will purchase additional Class A common shares from us in
approximately the same proportion as shown in the table above.

     The following table summarizes the compensation to be paid to the
underwriters by us and the proceeds, before expenses, payable to us. This
information is presented assuming either no exercise or full exercise by the
underwriters of their over-allotment option.

</Table>

     We estimate that the total expenses of this offering, excluding
underwriting discounts and commissions, will be approximately $425,000.

     We have agreed to indemnify the underwriters against certain civil
liabilities, including liabilities under the Securities Act of 1933 and
liabilities arising from breaches of representations and warranties contained in
the underwriting agreement, and to contribute to payments the underwriters may
be required to make in respect of any such liabilities.

                                       S-10


     Our directors, executive officers and the Moog Retirement Plan Trust have
agreed with the underwriters that for a period of 90 days following the date of
this prospectus supplement, they will not offer, sell, assign, transfer, pledge,
contract to sell or otherwise dispose of or hedge any shares of our Class A
common stock, Class B common stock or any securities convertible into or
exchangeable for shares of Class A common stock or Class B common stock. The
underwriters may, in their sole discretion, at any time without prior notice,
release all or any portion of the shares from the restrictions in any such
agreement. We have entered into a similar agreement with the underwriters. There
are no agreements between the underwriters and any of our directors, executive
officers or the Moog Retirement Plan Trust releasing them from these lock-up
agreements prior to the expiration of the 90-day period.

     The underwriters may engage in over allotment, stabilizing transactions,
syndicate covering transactions, penalty bids and passive market making in
accordance with Regulation M under the Securities Exchange Act of 1934. Over
allotment involves syndicate sales in excess of the offering size, which creates
a syndicate short position. Covered short sales are sales made in an amount no
greater than the number of shares available for purchase by the underwriters
under the over allotment option. The underwriters may close out a covered short
sale by exercising their over allotment option or purchasing shares in the open
market. Naked short sales are sales made in an amount in excess of the number of
shares available under the over allotment option. The underwriters must close
out any naked short sale by purchasing shares in the open market. Stabilizing
transactions permit bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. Syndicate covering
transactions involve purchases of the shares of Class A common stock in the open
market after the distribution has been completed in order to cover syndicate
short positions. Penalty bids permit the representatives to reclaim a selling
concession from a syndicate member when the shares of Class A common stock
originally sold by such syndicate member is purchased in a syndicate covering
transaction to cover syndicate short positions. Penalty bids may have the effect
of deterring syndicate members from selling to people who have a history of
quickly selling their shares. In passive market making, market makers in the
shares of Class A common stock who are underwriters or prospective underwriters
may, subject to certain limitations, make bids for or purchases of the shares of
Class A common stock until the time, if any, at which a stabilizing bid is made.
These stabilizing transactions, syndicate covering transactions and penalty bids
may cause the price of the shares of Class A common stock to be higher than it
would otherwise be in the absence of these transactions. These transactions may
be commenced and discontinued at any time.

     SG Cowen Securities Corporation has agreed to pay a fee of $250,000 upon
the closing of this offering to M&T Bank Corporation, for advice provided to SG
Cowen Securities Corporation in securing its engagement as underwriter in
connection with this offering.

     SG Cowen Securities Corporation may provide financial advisory services to
us from time to time in the ordinary course of its business. Banks affiliated
with underwriters participating in this offering are lenders under our existing
revolving and term loan credit facility and have committed to provide us with an
unsecured eighteen-month term loan to finance our purchase of the assets of the
Poly-Scientific division. In the event that we do not complete the
Poly-Scientific acquisition and more than ten percent of the net proceeds of the
offering is paid to banks affiliated with underwriters participating in this
offering, this offering will be conducted in accordance with NASD Conduct Rule
2710(c)(8).

                                 LEGAL MATTERS

prospectus supplement and accompanying prospectus will be passed upon for us by

                                   MOOG INC.

     We are a worldwide designer and manufacturer of high performance, precision
motion and fluid controls and control systems for a broad range of applications
in aerospace and industrial markets. Our products and systems are used in the
flight control of military and commercial aircraft, satellite positioning,
tactical and strategic missile steering and the steering of space launch
vehicles. They are also used in a wide variety of industrial applications,
including injection molding machines and power-generating turbines. Our global
base of military and commercial aerospace customers includes large original
equipment manufacturers, or OEMs, such as The Boeing Company, Lockheed Martin
Corporation and General Dynamics Corp., and the U.S. and foreign governments. We
also serve a diverse base of industrial machine manufacturers. We have
operations in 21 countries and, in fiscal 2002, sales from our foreign
operations were 27% of total sales. We design and manufacture our control
products and systems within three operating groups: aircraft controls; space
controls; and industrial controls. In fiscal 2002, sales in our aircraft
controls, space controls and industrial controls segments were 50%, 15% and 35%,
respectively, of our total sales.

     We have an excellent reputation in the industries we serve based on our
strong engineering and design capabilities and the reliability of our products.
We have developed close relationships with our customers that allow us to
effectively evaluate their precision control requirements and identify new
business opportunities. Our products and systems employ devices known as
servovalves and servoactuators that control the position, velocity or force of
moving objects with accuracy that can be measured in millionths of an inch. Not
only are these devices extremely accurate, they also respond to commands in as
little as thousandths of a second and as frequently as one hundred times a
second. We produce our products and systems by employing low cost facilities in
the Philippines and India and lean manufacturing strategies to manage our costs
and realize higher profits.

     Since our founding in 1951, our focus has been to design solutions to our
customers' complex motion control requirements. The technology behind our
products originated from our involvement on various missile programs and NASA
space missions in the 1950's and 1960's. We have adapted our technologies to
other product applications in aircraft controls and industrial controls. We
supply OEM flight control actuation systems for military and commercial
aircraft, steering controls for launch vehicles and propellant controls for
satellites. Our products have been used in almost every U.S. military aircraft
and numerous foreign military aircraft. We have an installed base of products on
the F-15 Eagle, the F/A-18 C/D Hornet, the B-2 Stealth Bomber and other
programs. We also supply controls for newer military aircraft programs such as
the F/A-18 E/F Super Hornet, the V-22 Osprey tiltrotor and the F-35 Joint Strike
Fighter. We supply steering controls for a number of strategic and tactical
missile programs, for NASA's Space Shuttle, for geosynchronous satellites and
for a number of launch vehicle programs. We supply flight controls to the major
commercial aircraft manufacturers, Boeing and Airbus Industrie. We also supply
servovalves for a wide range of global industrial applications.

     The markets we serve provide substantial opportunity for aftermarket sales.
Aftermarket sales are sales of spare and replacement parts and repair and
overhaul services. In fiscal 2002, aftermarket sales were 23% of our total
sales. The high technological content of our products and our reputation for
reliability encourages customers and end-users to use our routine repair and
maintenance services. For example, we provide product support to most major
commercial airlines.

                                  RISK FACTORS

     You should carefully consider the risks described below before investing in
our securities. You should also refer to the other information contained or
incorporated by reference in this prospectus and in any prospectus supplement.
If any of the following risks occur, our business could be harmed.

RISKS RELATED TO OUR INDUSTRY

THE MARKETS WE SERVE ARE CYCLICAL AND SENSITIVE TO DOMESTIC AND FOREIGN ECONOMIC
CONDITIONS AND EVENTS WHICH MAY CAUSE OUR OPERATING RESULTS TO FLUCTUATE.

     The markets we serve are sensitive to fluctuations in general business
cycles and domestic and foreign economic conditions and events. For example,
demand for our industrial controls products is dependent upon spending for
capital goods. In addition, the commercial airline industry is highly cyclical
and sensitive to fuel price increases, labor disputes and economic conditions.
These factors could result in a reduction in the amount of air travel. A
reduction in air travel would reduce orders for new aircraft for which we supply
flight controls and for spare parts and services and reduce our sales. A
reduction in air travel may also result in our commercial airline customers
being unable to pay our invoices on a timely basis or at all.

WE DEPEND HEAVILY ON GOVERNMENT CONTRACTS THAT MAY NOT BE FULLY FUNDED OR MAY BE
TERMINATED, AND THE FAILURE TO RECEIVE FUNDING OR THE TERMINATION OF ONE OR MORE
OF THESE CONTRACTS COULD REDUCE OUR SALES AND INCREASE OUR COSTS.

     Sales to the U.S. government and its prime contractors and subcontractors
represent a significant portion of our business. In fiscal 2002, sales under
U.S. government contracts represented 33% of our total sales, primarily within
our aircraft controls and space controls segments. Sales to foreign governments
represented 9% of our total sales. We expect that the percentage of our revenues
from government contracts will continue to be substantial in the future.
Government programs can be structured into a series of individual contracts. The
funding of these programs is generally subject to annual congressional
appropriations, and congressional priorities are subject to change. In addition,
government expenditures for defense programs may decline or these defense
programs may be terminated. A decline in governmental expenditures may result in
a reduction in the volume of contracts awarded to us. We may have resources
applied to specific government contracts and, if any of those contracts were
terminated, we may incur substantial costs redeploying these resources.

CONTRACTING IN THE DEFENSE INDUSTRY IS SUBJECT TO SIGNIFICANT REGULATION,
INCLUDING RULES RELATING TO BIDDING, BILLING AND ACCOUNTING KICKBACKS AND FALSE
CLAIMS, AND ANY NON-COMPLIANCE COULD SUBJECT US TO FINES AND PENALTIES OR
POSSIBLE DEBARMENT.

     Like all government contractors, we are subject to risks associated with
this contracting. These risks include the potential for substantial civil and
criminal fines and penalties. These fines and penalties could be imposed for
failing to follow procurement integrity and bidding rules, employing improper
billing practices or otherwise failing to follow cost accounting standards,
receiving or paying kickbacks or filing false claims. We have been, and expect
to continue to be, subjected to audits and investigations by government
agencies. The failure to comply with the terms of our government contracts could
harm our business reputation. It could also result in our progress payments
being withheld or our suspension or debarment from future government contracts.

ADVANCES IN TECHNOLOGY THAT SHIFT DEMAND FROM HYDRAULIC CONTROLS TO ELECTRIC
CONTROLS COULD RENDER SOME OF OUR PRODUCTS OBSOLETE.

     We supply industrial customers with high performance and application
specific motion controls. Advances in technology and changes in customer
preferences may shift the demand for hydraulic controls to electric controls.
This could render some of our hydraulic motion control products obsolete without
the opportunity for replacement.
                                        2


RISKS RELATED TO OUR BUSINESS

THE LOSS OF BOEING AS A CUSTOMER OR A SIGNIFICANT REDUCTION IN SALES TO BOEING
WOULD REDUCE OUR SALES AND EARNINGS.

     Our largest customer is Boeing. We provide Boeing with controls for both
military and commercial applications, which, in total, were 14% of our fiscal
2002 sales. Sales to Boeing's commercial airplane group were 8% of fiscal 2002
sales. These commercial sales are generally made under a long-term supply
agreement through 2008. Our commercial sales to Boeing have been decreasing
since 2001. These decreases result from Boeing's reduced production rates. The
loss of Boeing as a customer or a significant reduction in sales to Boeing would
significantly reduce our sales and earnings.

OUR SIGNIFICANT INDEBTEDNESS COULD LIMIT OUR OPERATIONAL AND FINANCIAL
FLEXIBILITY.

     We have incurred substantial debt to finance our growth. We had total debt
of $294 million, of which $268 million is long-term, at June 30, 2003. We also
had $119 million of unused borrowing capacity under short and long-term lines of
credit at that date. We may incur additional debt to fund our future growth. We
may not be able to service our debt or refinance our debt at maturity on terms
that are acceptable to us. Our debt service, consisting of interest expense and
required principal payments, was $27 million in the first nine months of fiscal
2003 and $32 million in fiscal 2002. The degree to which we are leveraged could
have other important consequences to us, including the following:

     - we must dedicate a substantial portion of our cash flow from operations
       to the payment of principal and interest on our debt;

     - a portion of our debt is at variable rates of interest, which makes us
       vulnerable to increases in interest rates; for example, interest expense
       for fiscal 2003 would increase $0.9 million for every percentage point
       increase in interest rates based on average variable rate debt
       outstanding during the first nine months of 2003; and

     - our debt instruments contain numerous financial and other restrictive
       covenants, such as restrictions on paying dividends, incurring additional
       debt, selling assets and making capital investments.

OUR DEFINED BENEFIT PENSION PLAN COSTS COULD SUBSTANTIALLY INCREASE AS A RESULT
OF MATTERS OUTSIDE OF OUR CONTROL.

     The funded status of our defined benefit pension plans is significantly
affected by matters outside our control including the investment performance of
the plan's assets and the level of market interest rates. Higher pension costs
and increased cash funding requirements could occur in future years if actual
plan investment performance or actual interest-rate levels, among other matters,
differ from the assumptions we used for these defined benefit plans.

A WRITE-OFF OF ALL OR PART OF OUR GOODWILL COULD ADVERSELY AFFECT OUR OPERATING
RESULTS AND NET WORTH AND CAUSE US TO VIOLATE COVENANTS IN OUR BANK CREDIT
AGREEMENT.

     Goodwill is a substantial portion of our assets. At June 30, 2003, goodwill
was $195 million of our total assets of $916 million. Our goodwill may increase
in the future since our strategy includes growing through acquisitions. We may
have to write-off all or part of our goodwill if its value becomes impaired.
Although this write-off would be a non-cash charge, it could reduce our earnings
and net worth significantly. A write-off of goodwill could also cause us to
violate covenants in our bank credit agreement that require a minimum level of
net worth. This could result in our being unable to borrow under the line of
credit portion of the credit agreement or in a need to refinance or renegotiate
the terms of our bank indebtedness.

                                        3


WE ENTER INTO FIXED PRICE CONTRACTS THAT COULD SUBJECT US TO LOSSES IN THE EVENT
THAT WE HAVE COST OVERRUNS.

     Most of the long-term contracts that we enter into are on a firm, fixed
price basis. This allows us to benefit from cost savings, but exposes us to the
risk of cost overruns. If our initial estimates are flawed, we can lose money on
these contracts. This could reduce our earnings.

OUR SALES GROWTH AND EARNINGS MAY BE REDUCED IF WE CANNOT IMPLEMENT OUR
ACQUISITION STRATEGY.

     Acquisitions are a key part of our growth strategy. Our ability to grow by
acquisition depends on the availability of suitable acquisition candidates at
reasonable prices. Growth by acquisition also involves risks that could
adversely affect our operating results, including:

     - difficulties in integrating the operations and personnel of acquired
       companies;

     - the potential impairment of a significant amount of intangible assets;
       and

     - the potential loss of key employees of acquired business.

OUR FACILITIES COULD BE DAMAGED BY CATASTROPHES WHICH COULD REDUCE OUR
PRODUCTION CAPACITY AND RESULT IN A LOSS OF CUSTOMERS.

     We have facilities in southern California, Japan and the Philippines. These
facilities account for approximately 25% of our manufacturing, assembly and test
capacity. Southern California, Japan, and the Philippines are particularly
susceptible to earthquakes. Although we carry property insurance, including
earthquake insurance and business interruption insurance, our inability to meet
customer schedules as a result of catastrophe may result in a loss of customers
or significant additional costs such as penalty claims under customer contracts.

THE FAILURE OF OUR PRODUCTS MAY RESULT IN CLAIMS AGAINST US THAT EXCEED OUR
INSURANCE COVERAGE AND REQUIRE US TO PAY SIGNIFICANT DAMAGES.

     Our products are used in applications where their failure is likely to
result in significant property loss and serious personal injury or death. We
carry aircraft and non-aircraft product liability insurance consistent with
industry norms. However, this insurance coverage may not be sufficient to fully
cover the payment of any potential claim.

OUR INTERNATIONAL OPERATIONS POSE CURRENCY AND OTHER RISKS THAT MAY ADVERSELY
IMPACT SALES AND EARNINGS.

     We have significant manufacturing and sales operations in foreign
countries. In addition, our domestic operations have sales to foreign customers.
Our financial results may be adversely affected by fluctuations in foreign
currencies and by the translation of the financial statements of our foreign
subsidiaries from local currencies into U.S. dollars. The translation of our
sales in foreign currencies, primarily the Euro and the Yen, to the U.S. dollar
had a $20.9 million positive impact on sales for the first nine months of fiscal
2003 using average exchange rates for the first nine months of fiscal 2003
compared to average exchange rates for the first nine months of fiscal 2002 and
a $2.0 million positive impact on sales for fiscal 2002 using average exchange
rates for fiscal 2002 compared to average exchange rates for fiscal 2001. In
addition, international operations are subject to other risks, including:

     - restrictions on dividends,

     - the tax impact of the repatriation of funds,

     - economic and political instability, and

     - possible expropriation of private property.

                                        4


OUR OPERATIONS ARE SUBJECT TO ENVIRONMENTAL LAWS AND THE COST OF COMPLIANCE WITH
THOSE LAWS MAY CAUSE US TO INCUR SIGNIFICANT COSTS.

     Our operations and facilities are subject to numerous stringent
environmental laws and regulations. Although we believe that we are in material
compliance with these laws and regulations, future changes in these laws,
regulations, or interpretations of them, or changes in the nature of our
operations may require us to make significant capital expenditures to ensure
compliance. We have been and are currently involved in environmental remediation
activities, the cost of which may become significant depending on discovery of
additional environmental exposures at sites that we currently own or operate and
at sites that we formerly owned or operated, or at sites to which we have sent
hazardous substances or wastes for treatment, recycling or disposal.

RISKS RELATED TO THIS OFFERING

THE VOTING RIGHTS OF THE CLASS A COMMON STOCK ARE LIMITED.

     The voting rights of the holders of Class A common stock are limited by our
certificate of incorporation. Holders of Class A common stock are entitled to
elect at least 25% of the board of directors, rounded up to the nearest whole
number, so long as the outstanding shares of Class A common stock are at least
10% of the aggregate number of outstanding shares of Class A common stock and
Class B common stock combined. Currently, the holders of Class A common stock
are entitled, as a class, to elect three directors. The holders of the Class B
common stock are entitled, as a class, to elect the remaining seven directors.
On all other matters except as is required by law, the Class A and Class B
common stock vote together as a single class with each share of Class A common
stock entitled to a one-tenth vote per share and each share of Class B common
stock entitled to one vote per share.

OUR OFFICERS AND DIRECTORS AND SHAREHOLDERS AFFILIATED WITH THEM CONTROL THE
VOTE OF A MAJORITY OF OUR VOTING STOCK AND AS A RESULT EXERT SIGNIFICANT
INFLUENCE OVER US, AND MAY HAVE INTERESTS THAT CONFLICT WITH THOSE OF OTHER
SHAREHOLDERS, INCLUDING PURCHASERS OF CLASS A COMMON STOCK.

     As of June 30, 2003, approximately 78.1% of the Class B common stock and
approximately 10.1% of the Class A common stock was held in the aggregate by the
Moog Inc. Savings and Stock Ownership Plan Trust, the Moog Inc. Retirement Plan
Trust, relatives of the late Jane B. Moog subject to The Moog Family Agreement
as to Voting and our officers and directors. These shareholders as a group
possess the voting power to elect a majority of the board of directors and to
effectively control our business policies and affairs.

THERE ARE MECHANISMS IN PLACE TO INHIBIT TAKEOVER ATTEMPTS, WHICH MAY REDUCE OR
ELIMINATE ABILITY TO SELL SHARES OF CLASS A COMMON STOCK FOR A PREMIUM.

     There are mechanisms in place that could prevent or delay a takeover of us.
These mechanisms include:

     - the limited voting rights of the Class A common stock and the fact that
       approximately 10.1% of the Class A and approximately 78.1% of the Class B
       common stock, representing approximately 52.4% of the voting power of our
       outstanding common stock, is owned or controlled by our affiliates;

     - our ability under our certificate of incorporation to issue additional
       shares of Class B common stock and shares of "blank check" preferred
       stock without action of the shareholders;

     - our outstanding Series B preferred stock which is held by our officers
       and directors and which may vote as a class on takeover transactions in
       which the rights of the Series B preferred stock would be prejudiced;

     - provisions of our certificate of incorporation and bylaws which create a
       staggered board of directors with each director elected for a three-year
       term; and

                                        5


     - provisions of New York corporate law which impose limitations on persons
       proposing to acquire us in a transaction not approved by our board of
       directors.

OUR STOCK PRICE MAY BE VOLATILE AND COULD EXPERIENCE SIGNIFICANT DECLINES.

     The market price of our Class A common stock has experienced and may
continue to experience significant price fluctuations which may be unrelated to
our financial performance. The volatility of our Class A common stock may have
been influenced by its low historical trading volume. For example, from January
1, 2001 to June 30, 2003 the closing prices of our Class A common stock have
ranged from $18.92 per share to $42.88 per share.

                       RATIO OF EARNINGS TO FIXED CHARGES

     Our ratio of earnings to fixed charges for each of the periods indicated is
as follows:

     - interest on all indebtedness

     - amortization of capitalized expenses related to debt,

     - an interest factor attributable to rentals,

     - preferred stock dividends.

                                USE OF PROCEEDS

     Unless otherwise indicated in a prospectus supplement, we expect to use the
net proceeds from the sale of the securities offered hereby for general
corporate purposes, which may include working capital, acquisition financing,
capital expenditures and the repayment of debt obligations. Further details
relating to the use of the net proceeds of any of the securities will be set
forth in the applicable prospectus supplement.

                         DESCRIPTION OF DEBT SECURITIES

     If we issue any debt securities offered by this prospectus and any
accompanying prospectus supplement we will issue them under an indenture to be
entered into by us and a trustee to be identified in the applicable prospectus
supplement, as trustee. The terms of the debt securities will include those

statement in which this prospectus is included. We may use another indenture for
a series of debt securities and, if we do so, we will provide details in a
prospectus supplement. We will file the form of any other indenture with the SEC
at the time we use it. Each indenture will be subject to and governed by the
terms of the Trust Indenture Act of 1939.

     We may offer under this prospectus up to $120,000,000 aggregate principal
amount of debt securities; or if debt securities are issued at a discount, or in
a foreign currency, foreign currency units or composite currency, the principal
amount as may be sold for an initial public offering price of up to
$120,000,000. Unless otherwise specified in the applicable prospectus
supplement, the debt securities will represent direct, unsecured obligations of
Moog and will rank equally with all of our other unsecured indebtedness.

     The following statements relating to the debt securities and the indenture
are summaries and do not purport to be complete, and are subject in their
entirety to the detailed provisions of the indenture.

GENERAL

     We may issue the debt securities in one or more series with the same or
various maturities, at par, at a premium, or at a discount. We will describe the
particular terms of each series of debt securities in a prospectus supplement
relating to that series, which we will file with the SEC. To review the terms of
a series of debt securities, you must refer to both the prospectus supplement
for the particular series and, if applicable, to the description of debt
securities in this prospectus.

     The prospectus supplement will set forth the following terms of the debt
securities in respect of which this prospectus is delivered:

          (1) the title;

          (2) the aggregate principal amount;

          (3) the issue price or prices (expressed as a percentage of the
     aggregate principal amount thereof);

          (4) any limit on the aggregate principal amount;

          (5) the date or dates on which principal is payable;

          (6) the interest rate or rates (which may be fixed or variable) or, if
     applicable, the method used to determine the rate or rates;

          (7) the date or dates from which the interest, if any, will be payable
     and any regular record date for the interest payable;

          (8) the place or places where principal and, if applicable, premium
     and interest, is payable;

          (9) the terms and conditions upon which Moog may, or the holders may
     require Moog to, redeem or repurchase the debt securities;

          (10) the denominations in which the debt securities may be issuable,
     if other than denominations of $1,000 or any integral multiple thereof;

          (11) whether the debt securities are to be issuable in the form of
     certificated debt securities (as described below) or global debt securities
     (as described below);

          (12) the portion of principal amount that will be payable upon
     declaration of acceleration of the maturity date if other than the
     principal amount of the debt securities;

          (13) the currency of denomination;

          (14) the designation of the currency, currencies or currency units in
     which payment of principal and, if applicable, premium and interest, will
     be made;

          (15) if payments of principal and, if applicable, premium or interest,
     on the debt securities are to be made in one or more currencies or currency
     units other than the currency of denomination, the manner in which the
     exchange rate with respect to these payments will be determined;

          (16) if amounts of principal and, if applicable, premium and interest
     may be determined (a) by reference to an index based on a currency or
     currencies other than the currency of denomination or designation or (b) by
     reference to a commodity, commodity index, stock exchange index or
     financial index, then the manner in which these amounts will be determined;

          (17) the provisions, if any, relating to any security provided for the
     debt securities;

          (18) any addition to or change in the covenants and/or the
     acceleration provisions described in this prospectus or in the indenture;
                                        7


          (19) any events of default, if not otherwise described, begin under
     "Events of Default";

          (20) the terms and conditions for conversion into or exchange for
     shares of common stock or preferred stock;

          (21) any other terms, which may modify or delete any provision of the

          (23) the terms and conditions, if any, upon which the debt securities
     shall be subordinated in right of payment to other indebtedness of Moog.

     We may issue discount debt securities that provide for an amount less than
the stated principal amount to be due and payable upon acceleration of the
maturity of the debt securities in accordance to the terms of the indenture. We
may also issue debt securities in bearer form, with or without coupons. If we
issue discount securities or debt securities in bearer form, we will describe
United States federal income tax considerations and other special considerations
that apply to the debt securities in the applicable prospectus supplement.

     We may issue debt securities denominated in or payable in a foreign
currency or currencies or a foreign currency unit or units. If we do so, we will
describe the restrictions, elections, general tax considerations, specific terms
and other information with respect to the issue of debt securities and the
foreign currency or currencies or foreign currency unit or units in the
applicable prospectus supplement.

EXCHANGE AND/OR CONVERSION RIGHTS

     If we issue debt securities that may be exchanged for or converted into
shares of common stock or preferred stock, we will describe the terms of
exchange or conversion in the prospectus supplement relating to those debt
securities.

TRANSFER AND EXCHANGE

     We may issue debt securities that will be represented by either:

          (1) "book-entry securities," which means that there will be one or
     more global securities registered in the name of The Depository Trust
     Company, as depository, or a nominee of the depository; or

          (2) "certificated securities," which means that they will be
     represented by a certificate issued in definitive registered form.

     We will specify in the prospectus supplement applicable to a particular
offering whether the debt securities offered will be book-entry or certificated
securities. Except as set forth under "-- Global Debt Securities and Book Entry
System" below, book-entry debt securities will not be issuable in certificated
form.

CERTIFICATED DEBT SECURITIES

     If you hold certificated debt securities that have been offered by this
prospectus, you may transfer or exchange them at the trustee's office or at the
paying agency in accordance with the terms of the indenture. You will not be
charged a service charge for any transfer or exchange of certificated debt
securities, but may be required to pay an amount sufficient to cover any tax or
other governmental charge payable in connection with the transfer or exchange.

     You may effect the transfer of certificated debt securities and of the
right to receive the principal of, premium, and/or interest, if any, on your
certificated debt securities only by surrendering the certificate

                                        8


representing your certificated debt securities and having us or the trustee
issue a new certificate to the new holder.

GLOBAL DEBT SECURITIES AND BOOK ENTRY SYSTEM

     The Depository Trust Company, as depository, has indicated that it would
follow the procedures described below to book-entry debt securities.

     Only participants that have accounts with the depository for the related
global debt security or persons that hold interests through these participants
may own beneficial interests in book-entry debt securities. Upon the issuance of
a global debt security, the depository will credit, on its book-entry
registration and transfer system, each participants' account with the principal
amount of the book-entry debt securities represented by the global debt security
that is beneficially owned by that participant. The accounts to be credited will
be designated by any dealers, underwriters or agents participating in the
distribution of the book-entry debt securities. Ownership of book-entry debt
securities will be shown on, and the transfer of the ownership interests will be
effected only through, records maintained by the depository for the related
global debt security (with respect to interests of participants) and on the
records of participants (with respect to interests of persons holding through
participants). The laws of some states may require that certain purchasers of
securities take physical delivery of the securities in definitive form. These
laws may impair your ability to own, transfer or pledge beneficial interests in
book-entry debt securities.

     So long as the depository for a global debt security, or its nominee, is
the registered owner of the global debt security, the depository or its nominee
will be considered the sole owner or holder of the book-entry debt securities
represented by the global debt security for all purposes under the indenture.
Except as described below, beneficial owners of book-entry debt securities will
not be entitled to have these securities registered in their names, will not
receive or be entitled to receive physical delivery of a certificate in
definitive form representing these securities and will not be considered the
owners or holders of these securities under the indenture. Accordingly, each
person who beneficially owns book-entry debt securities and desires to exercise
their rights as a holder under the indenture, must rely on the procedures of the
depository for the related global debt security and, if this person is not a
participant, on the procedures of the participant through which that person owns
its interest, to exercise such rights.

     We understand, however, that under existing industry practice, the
depository will authorize the persons on whose behalf it holds a global debt
security to exercise certain rights of holders of debt securities. Moog and its
agents, the trustee, and any of its agents, will treat as the holder of a debt
security the persons specified in a written statement of the depository with
respect to that global debt security for purposes of obtaining any consents or
directions required to be given by holders of the debt securities under the
indenture.

     Payments of principal and, if applicable, premium and interest, on
book-entry debt securities will be made to the depository or its nominee, as the
case may be, as the registered holder of the related global debt security. Moog
and its agents, the trustee, and any of its agents will not have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the global debt
security or for maintaining, supervising or reviewing any records relating to
the beneficial ownership interests.

     We expect that the depository, upon receipt of any payment of principal of,
premium, if any, or interest, if any, on a global debt security, will
immediately credit participants' accounts with payments in amounts proportionate
to the amounts of book-entry debt securities held by each participant as shown
on the records of the depository. We also expect that payments by participants
to owners of beneficial interests in book-entry debt securities held through
these participants will be governed by standing customer instructions and
customary practices, as is now the case with the securities held for the
accounts of customers in bearer form or registered in "street name." These
payments will be the responsibility of the participants.

                                        9


     If the depository is at any time unwilling or unable to continue as
depository or ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, we will appoint a successor depository. If we do not
appoint a successor depository registered as a clearing agency under the
Securities Exchange Act of 1934 within 90 days, we will issue certificated debt
securities in exchange for each global debt security. In addition, we may at any
time and in our sole discretion determine not to have the book-entry debt
securities of any series represented by one or more global debt securities. In
that case, we will issue certificated debt securities in exchange for the global
debt securities of that series. Global debt securities will also be exchangeable
by the holders for certificated debt securities if an event of default with
respect to the book-entry debt securities represented by that global debt
securities has occurred and is continuing. Any certificated debt securities
issued in exchange for a global debt security will be registered in the name or
names that the depository instructs the trustee. We expect that these
instructions will be based upon directions received by the depository from
participants.

     We obtained the information in this section concerning the depository and
the depository's book-entry system from sources we believe to be reliable, but
we do not take any responsibility for the accuracy of this information.

NO PROTECTION IN THE EVENT OF CHANGE OF CONTROL

     The indenture does not have any covenants or other provisions providing for
a put or increased interest or otherwise that would afford holders of debt
securities additional protection in the event of a recapitalization transaction,
a change of control of Moog or a highly leveraged transaction. If we offer any
covenants of this type or provisions with respect to any debt securities in the
future, we will describe them in the applicable prospectus supplement.

COVENANTS

     Unless otherwise indicated in this prospectus or a prospectus supplement,
the debt securities will not have the benefit of any covenants that limit or
restrict our business or operations, the pledging of our assets or the
incurrence by us of indebtedness. We will describe in the applicable prospectus
supplement any material covenants of a series of debt securities.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     We have agreed in the indenture that we will not consolidate with or merge
into any other person or convey, transfer, sell or lease our properties and
assets substantially as an entirety to any person, unless:

          (1) the person formed by the consolidation or into or with which we
     are merged or the person to which our properties and assets are conveyed,
     transferred, sold or leased, is a corporation organized and existing under
     the laws of the United States, any State thereof or the District of
     Columbia and, if we are not the surviving person, the surviving person has
     expressly assumed all of our obligations, including the payment of the
     principal of and, premium, if any, and interest on the debt securities and
     the performance of the other covenants under the indenture; and

          (2) immediately after giving effect to the transaction, no event of
     default, and no event which, after notice or lapse of time or both, would
     become an event of default, has occurred and is continuing under the
     indenture.

EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, the
following events will be events of default under the indenture with respect to
debt securities of any series:

          (1) we fail to pay any principal of, or premium, if any, when it
     becomes due;

          (2) we fail to pay any interest within 30 days after it becomes due;

                                        10


          (3) we fail to observe or perform any other covenant in the debt
     securities or the indenture for 90 days after written notice from the
     trustee or the holders of not less than 25% in aggregate principal amount
     of the outstanding debt securities of that series; and

          (4) certain events occur involving bankruptcy, insolvency or
     reorganization of Moog or any of our significant subsidiaries.

     The trustee may withhold notice to the holders of the debt securities of
any series of any default, except in payment of principal or premium, if any, or
interest on the debt securities of that series, if the trustee considers it to
be in the best interest of the holders of the debt securities of that series to
do so.

     If an event of default (other than an event of default resulting from
certain events of bankruptcy, insolvency or reorganization) occurs, and is
continuing, then the trustee or the holders of not less than 25% in aggregate
principal amount of the outstanding debt securities of any series may accelerate
the maturity of the debt securities.

     If this happens, the entire principal amount of all the outstanding debt
securities of that series plus accrued interest to the date of acceleration will
be immediately due and payable. At any time after an acceleration, but before a
judgment or decree based on the acceleration is obtained by the trustee, the
holders of a majority in aggregate principal amount of outstanding debt
securities of that series may rescind and annul the acceleration if (1) all
events of default (other than nonpayment of accelerated principal, premium or
interest) have been cured or waived, (2) all overdue interest and overdue
principal has been paid and (3) the rescission would not conflict with any
judgment or decree.

     If an event of default resulting from certain events of bankruptcy,
insolvency or reorganization occurs, the principal, premium and interest amount
with respect to all of the debt securities of any series shall be due and
payable immediately without any declaration or other act on the part of the
trustee or the holders of the debt securities of that series.

     The holders of a majority in principal amount of the outstanding debt
securities of a series shall have the right to waive any existing default or
compliance with any provision of the indenture or the debt securities of that
series and to direct the time, method and place of conducting any proceeding for
any remedy available to the trustee, subject to certain limitations specified in
the indenture.

     No holder of any debt security of a series will have any right to institute
any proceeding with respect to the indenture or for any remedy under the
indenture, unless:

          (1) the holder gives to the trustee written notice of a continuing
     event of default;

          (2) the holders of at least 25% in aggregate principal amount of the
     outstanding debt securities of that series make a written request and offer
     reasonable indemnity to the trustee to institute proceeding as a trustee;

          (3) the trustee fails to institute proceeding within 60 days of the
     request; and

          (4) the holders of a majority in aggregate principal amount of the
     outstanding debt securities of that series do not give the trustee a
     direction inconsistent with their request during the 60-day period.

     However, these limitations do not apply to a suit instituted for payment on
debt securities of any series on or after the due dates expressed in the debt
securities.

MODIFICATION AND WAIVER

     From time to time, we and the trustee may, without the consent of holders
of the debt securities of one or more series, amend the indenture or the debt
securities of one or more series, or supplement the indenture, for certain
specified purposes, including:

          (1) to provide that the surviving entity following a change of control
     of Moog permitted under the indenture shall assume all of our obligations
     under the indenture and debt securities;

                                        11


          (2) to provide for uncertificated debt securities in addition to
     certificated debt securities;

          (3) to comply with any requirements of the SEC under the Trust
     Indenture Act of 1939;

          (4) to cure any ambiguity, defect or inconsistency, or make any other
     change that does not adversely affect the rights of any holder of the debt
     securities;

          (5) to issue and establish the form and terms and conditions of the
     debt securities; and

          (6) to appoint a successor trustee under the indenture with respect to
     one or more series of the debt securities.

     From time to time we and the trustee may, with the consent of holders of at
least a majority in principal amount of the outstanding debt securities, amend
or supplement the indenture or the debt securities, or waive compliance in a
particular instance by us with any provision of the indenture or the debt
securities; but without the consent of each holder affected by the action, we
may not modify or supplement the indenture or the debt securities or waive
compliance with any provision of the indenture or the debt securities in order
to:

          (1) reduce the amount of debt securities whose holders must consent to
     an amendment, supplement, or waiver to the indenture or the debt security;

          (2) reduce the rate of or change the time for payment of interest;

          (3) reduce the principal of or premium on or change the stated
     maturity;

          (4) make any debt security payable in money other than that stated in
     the debt security;

          (5) change the amount or time of any payment required or reduce the
     premium payable upon any redemption, or change the time before which no
     redemption of this type may be made;

          (6) waive a default on the payment of the principal of, interest on,
     or redemption payment;

          (7) take any other action otherwise prohibited by the indenture to be
     taken without the consent of each holder affected by that action.

DEFEASANCE AND DISCHARGE OF DEBT SECURITIES AND CERTAIN COVENANTS IN CERTAIN
CIRCUMSTANCES

     The indenture permits us, at any time, to elect to discharge our
obligations with respect to one or more series of debt securities by following
certain procedures described in the indenture. These procedures will allow us
either:

          (1) to defease and be discharged from any and all of our obligations
     with respect to any debt securities except for the following obligations
     (which discharge is referred to as "legal defeasance"):

             (a) to register the transfer or exchange of the debt securities;

             (b) to replace temporary or mutilated, destroyed, lost or stolen
        debt securities;

             (c) to compensate and indemnify the trustee; or

             (d) to maintain an office or agency in respect of the debt
        securities and to hold monies for payment in trust; or

          (2) to be released from our obligations with respect to the debt
     securities under certain covenants contained in the indenture, as well as
     any additional covenants which may be contained in the applicable
     prospectus supplement (which release is referred to as "covenant
     defeasance").

                                        12


     In order to exercise either defeasance option, we must deposit with the
trustee or other qualifying trustee, in trust for this purpose:

          (1) money;

          (2) U.S. Government Obligations (as described below) or Foreign
     Government Obligations (as described below) which through the scheduled
     payment of principal and interest in accordance with their terms will
     provide money; or

          (3) a combination of money and/or U.S. Government Obligations and/or
     Foreign Government Obligations sufficient in the written opinion of a
     nationally-recognized firm of independent accountants to provide money;

which in each case specified in clauses (1) through (3) above, provides a
sufficient amount to pay the principal of, premium, if any, and interest, if
any, on the debt securities of a series, on the scheduled due dates or on a
selected date of redemption in accordance with the terms of the indenture.

     In addition, defeasance may be effected only if, among other things:

          (1) in the case of either legal or covenant defeasance, we deliver to
     the trustee an opinion of counsel, as specified in the indenture, stating
     that as a result of the defeasance neither the trust nor the trustee will
     be required to register as an investment company under the Investment
     Company Act of 1940;

          (2) in the case of legal defeasance, we deliver to the trustee an
     opinion of counsel stating that we have received from, or there has been
     published by, the Internal Revenue Service a ruling to the effect that, or
     there has been a change in any applicable federal income tax law with the
     effect that, and the opinion shall confirm that, the holders of outstanding
     debt securities will not recognize income, gain or loss for United States
     federal income tax purposes solely as a result of the legal defeasance and
     will be subject to United States federal income tax on the same amounts, in
     the same manner, including as a result of prepayment, and at the same times
     as would have been the case if a defeasance had not occurred;

          (3) in the case of covenant defeasance, we deliver to the trustee an
     opinion of counsel to the effect that the holders of the outstanding debt
     securities will not recognize income, gain or loss for United States
     federal income tax purposes as a result of the covenant defeasance and will
     be subject to United States federal income tax on the same amounts, in the
     same manner and at the same times as would have been the case if a covenant
     defeasance had not occurred; and

          (4) certain other conditions described in the indenture are satisfied.

     If we fail to comply with our remaining obligations under the indenture and
applicable supplemental indenture after a covenant defeasance of the indenture
and applicable supplemental indenture, and the debt securities are declared due
and payable because of the occurrence of any undefeased event of default, the
amount of money and/or U.S. Government Obligations and/or Foreign Government
Obligations on deposit with the trustee could be insufficient to pay amounts due
under the debt securities of that series at the time of acceleration. We will,
however, remain liable in respect of these payments.

     The term "U.S. Government Obligations" as used in the above discussion
means securities which are direct obligations of or non-callable obligations
guaranteed by the United States of America for the payment of which obligation
or guarantee the full faith and credit of the United States of America is
pledged.

     The term "Foreign Government Obligations" as used in the above discussion
means, with respect to debt securities of any series that are denominated in a
currency other than U.S. dollars (1) direct obligations of the government that
issued or caused to be issued the currency for the payment of which obligations
its full faith and credit is pledged or (2) obligations of a person controlled
or supervised by or acting as an agent or instrumentality of that government the
timely payment of which is unconditionally

                                        13


guaranteed as a full faith and credit obligation by that government, which in
either case under clauses (1) or (2), are not callable or redeemable at the
option of the issuer.

REGARDING THE TRUSTEE

     We will identify the trustee with respect to any series of debt securities
in the prospectus supplement relating to the debt securities. The holders of a
majority in principal amount of the then outstanding debt securities of any
series may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the trustee. If an event of default occurs
and is continuing, the trustee, in the exercise of its rights and powers, must
use the degree of care and skill of a prudent person in the conduct of his or
her own affairs. Subject to this provision, the trustee will be under no
obligation to exercise any of its rights or powers under the indenture at the
request of any of the holders of the debt securities, unless they have offered
to the trustee reasonable indemnity or security.

                          DESCRIPTION OF CAPITAL STOCK

     Our authorized capital stock consists of 30,000,000 shares of Class A
common stock, par value $1.00 per share, 10,000,000 shares of Class B common
stock, par value $1.00 per share and 10,000,000 shares of preferred stock, par
value $1.00 per share. As of July 21, 2003, we had outstanding 13,064,843 shares
of Class A common stock, 2,155,183 shares of Class B common stock and 83,771
shares of 9% Cumulative, Convertible, Exchangeable, Preferred Stock, Series B,
$1.00 par value, or Series B Preferred Stock. The following description of our
capital stock is a summary only and is derived from our certificate of
incorporation, which is incorporated by reference into this prospectus.

COMMON STOCK

     The Class A common stock and Class B common stock share equally in our
earnings and are identical except with respect to rights on voting, dividends
and share distributions and convertibility.

     Voting Rights.  The Class A common stock and Class B common stock vote as a
single class on all matters except election of directors and except as required
by law. Holders of Class A common stock are entitled to elect at least 25% of
the board of directors, rounded up to the nearest whole number, so long as the
outstanding shares of Class A common stock are at least 10% of the aggregate
number of outstanding shares of Class A common stock and Class B common stock
combined. The holders of Class B common stock elect the remaining directors.
Currently, the holders of Class A common stock are entitled, as a class, to
elect three directors. The holders of the Class B common stock are entitled, as
a class, to elect our remaining seven directors. On all other matters, the
holders of Class A common stock are entitled to one-tenth of a vote. Each share
of Class B common stock is entitled to one vote. If the outstanding shares of
Class A common stock become less than 10% of the aggregate number of outstanding
shares of both classes combined, the holders of Class A common stock would not
have the right to elect 25% of the board of directors. Directors would then be
elected by all shareholders voting as a single class, with holders of Class A
common stock having a one-tenth vote per share and holders of Class B common
stock having one vote per share.

     Dividends and Share Distributions.  Dividends may be paid on Class A common
stock without paying a dividend on Class B common stock. No dividend may be paid
on Class B common stock unless at least an equal dividend is paid on Class A
common stock. Payment of dividends is limited by our bank credit facility.

     Share distributions in shares of Class A common stock or Class B common
stock may be paid only as follows. Shares of Class A common stock are paid to
holders of shares of Class A common stock or, if there is no Class A common
stock outstanding, to holders of Class B common stock. Shares of Class B common
stock are paid to holders of Class B common stock. The same number of shares
must be paid in respect of each outstanding share of Class A common stock and
Class B common stock.

     We may not combine or subdivide shares of either class of common stock
without at the same time proportionally subdividing or combing shares of the
other class.

     Conversion.  Each share of Class B common stock is convertible at the
option of the holder at any time into Class A common stock on a one-for-one
basis.

PREFERRED STOCK

     The Series B Preferred Stock is our only outstanding class of preferred
stock. As of July 21, 2003, there were 83,771 shares of Series B Preferred Stock
outstanding. The Series B Preferred Stock is entitled to quarterly cumulative
dividends at 9% per annum based on the par value of the shares. In the event we
fail to pay the dividend for a period of eight consecutive quarters, the Series
B Preferred Stock, voting as a class, is entitled to elect two directors who
would otherwise be elected by the Class B common stock. The Series B Preferred
Stock will be automatically exchanged for shares of Class A common stock at the
conversion rate on January 1, 2004. The Series B Preferred Stock also has the
right to receive payment on our liquidation before payment is made to holders of
the common stock. The Series B Preferred Stock is convertible into Class A
common stock at a rate of .128775 shares of common stock per share of Series B
Preferred Stock at any time at the option of the holder. The Series B Preferred
Stock votes with the common stock, on the basis of one vote per share, on any
proposal for the termination of our existence by reason of dissolution,
liquidation, sale or mortgage of a substantial part of our assets, or a merger,
consolidation or similar business combination. Pursuant to the New York Business
Corporation Law, the Series B Preferred Stock is entitled to vote as a class on
takeover transactions in which the rights of the Series B Preferred Stock are
prejudiced. The Series B Preferred Stock is owned by nine of our current
officers. These officers have agreed among themselves that all shares of Series
B Preferred Stock owned by them will be voted in a manner determined by the
holders of a majority of the shares. The agreement contains restrictions on the
ability of any party to remove their shares from the provisions of the
agreement, to transfer shares, or otherwise convert the shares that are subject
to the agreement. The agreement continues in force until January 2, 2004, unless
any of the following events occur prior to that date:

     - we cease to do business;

     - our bankruptcy, receivership or dissolution;

     - upon the mutual agreement of the holders of 85% of the shares of Series B
       Preferred Stock bound by the agreement; or

     - whenever there are only two surviving holders bound by the agreement.

     Our board of directors is authorized, without shareholder action, to issue
additional shares of preferred stock in one or more series. The board has the
discretion to determine the rights, preferences and limitations of each series,
including voting rights, dividend rights, conversion rights, redemption
privileges and liquidation preferences. Satisfaction of any dividend preference
of outstanding shares of preferred stock would reduce the amount of funds
available for the payment of dividends on shares of common stock. In some
circumstances, the issuance of shares of preferred stock may render more
difficult or tend to discourage a merger, tender offer or proxy contest, the
assumption of control by a holder of a large block of our securities or the
removal of incumbent management. We have no current intention to issue any
additional shares of preferred stock.
