             This Schedule 13E-4 relates to an offer by National Patent
   Development Corporation (the "Company") (i) to exchange common stock,
   par value $.01 per share (the "Common Stock"), of the Company with a
   market value of SFr. 1,000 for each SFr. 1,000 in principal amount of
   the Old Swiss Franc Bonds validly tendered and not withdrawn prior to
   the Expiration Date, and (ii) to exchange Common Stock with a market
   value of US $1,000 for each US $1,000 in principal amount of Old U.S.
   Dollar Bonds validly tendered and not withdrawn prior to the Expiration
   Date.  Interest accrued on the Bonds up to the Payment Date will be paid
   in shares of Common Stock of the Company for each SFr. 1,000 principal
   amount of Old Swiss Franc Bonds (such amounts referred to collectively
   as "Swiss Bond Accrued Interest") and for each US $1,000 principal
   amount of the Old U.S. Dollar Bonds (such amount referred to as "U.S.
   Bond Accrued Interest," and together with the Swiss Bond Accrued
   Interest, the "Accrued Interest").  Fractional shares of Common Stock
   resulting from such exchange will be rounded up to the nearest integral
   multiple.

             The Company is concurrently making separate offers to (i) U.S.
   holders to purchase any and all Bonds held by such holders (the "United
   States Offer") and (ii) holders of Bonds held by persons that are not in
   the United States and are not U.S. persons (the "Foreign Offer").  As
   used herein, the term "Offer" shall refer collectively to the United
   States Offer and the Foreign Offer.  In connection with both of the
   above, a copy of the Company's Offering Circular dated June 10, 1994
   with respect to the United States Offer (the "U.S. Offering Circular")
   and a copy of the Company's Offering Circular dated June 10, 1994 with
   respect to the Foreign Offer (the "Foreign Offering Circular") are
   attached hereto as Exhibits (a)(1) and (2) and are incorporated herein
   by reference.  As used herein, the term "Offering Circular" shall refer
   collectively to the U.S. Offering Circular and the Foreign Offering
   Circular.

   Item      Response or Cross-Reference to
             the Offering Circular

             outstanding Bonds validly tendered in response to the Offer
             and not withdrawn prior to the Expiration Date.  The Company
             reserves the right to exchange Bonds representing up to 62% of
             the aggregate principal amount of the outstanding Bonds
             pursuant to the Offer.  If more than 60% of the aggregate
             principal amount of the outstanding Bonds have been properly

Company is making a separate offer on the same terms and for the same
consideration as the Offer to foreign holders of the Bonds (the "Foreign
Offer").

     On April 30, 1994, there were outstanding SFr. 8,635,000 of the 6%
Convertible Bonds due 1995, SFr. 3,520,000 of the 5 3/4% Convertible Bonds due
1995, SFr. 4,735,000 of the 5 5/8% Convertible Bonds due 1996, SFr. 7,401,000 of
the 8% Bonds due 1995 and US $3,926,000 of the 7% Dual Currency Convertible
Bonds due 1996.  Interest accrued on the Bonds up to July 22, 1994, or, if the
Company shall have extended the Expiration Date, the tenth (10th) business day
after such adjusted Expiration Date (the "Payment Date"), will be paid in shares
of Common Stock of the Company for each SFr. 1,000 principal amount of each
respective class of Old Swiss Franc Bonds (such amounts referred to collectively
as "Swiss Bond Accrued Interest") and for each US $1,000 principal amount of the
Old U.S. Dollar Bonds (such amount referred to as "U.S. Bond Accrued Interest,"
and together with the Swiss Bond Accrued Interest, the "Accrued Interest").

     In the event that Bonds in excess of 60% of the aggregate principal amount
of the outstanding Bonds have been properly tendered by the holders thereof
prior to the Expiration Date and not withdrawn pursuant to the Offer and the
Foreign Offer, the Company may, upon the terms and subject to the conditions of
the Offer, either (i) accept Bonds tendered on a pro rata basis according to the
aggregate principal amount of all Bonds properly tendered by the holders thereof
prior to the Expiration Date and not withdrawn pursuant to the Offer and the
Foreign Offer or (ii) amend the terms of the Offer by notice to the holders of
the Bonds, in which case the Offer shall remain open for an additional ten (10)
business days from the date that such notice is first given.  If not more than
60% in aggregate principal amount of the outstanding Bonds are properly tendered
by the Expiration Date and not withdrawn pursuant to the Offer and the Foreign
Offer, all Bonds so tendered and not withdrawn will, upon the terms and subject
to the conditions of the Offer and the Foreign Offer, be exchanged.  The Company
has the right, in its sole discretion, to waive any such conditions.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MAKING
OF THE OFFER. HOWEVER, NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS IS
MAKING ANY RECOMMENDATION TO ANY HOLDER OF BONDS TO TENDER BONDS PURSUANT TO
THE OFFER. EACH HOLDER OF BONDS SHOULD MAKE ITS OWN DECISION WHETHER TO TENDER
ITS BONDS AFTER READING THIS OFFERING CIRCULAR.

     The Common Stock to be issued pursuant to the Offer has not been registered
under the United States Securities Act of 1933, as amended (the "Securities
Act"), and may not be offered or sold except in transactions exempt from the
registration requirements of the Securities Act or pursuant to an effective
registration statement.  In recognition of the fact that exchanging holders of
Bonds ("Holders"), even though holding shares of Common Stock for investment,
may wish to be legally permitted to sell such stock when they deem appropriate,
the Company has agreed to prepare and file with the Securities and Exchange
Commission (the "Commission") a registration statement with respect to the
resale of the Common Stock from time to time on the American Stock Exchange,
Inc. or Pacific Stock Exchange, Inc., in privately-negotiated transactions or
otherwise.  The Company has agreed to use its best efforts to cause such
registration statement to become effective on or before August 1, 1994.  If such
registration statement is not declared effective by the Commission by August 15,
1994, each exchanging holder will have the option to withdraw the Bonds tendered
by it and to renounce its rights to the Common Stock received for its account in
exchange for such Bonds.  Notice of such withdrawal must be given to the Company
prior to August 30, 1994.  Offers and sales of Common Stock would constitute a
violation of United States law unless made in compliance with the registration
requirements of the Securities Act or pursuant to an exemption therefrom.

     In order to exchange Bonds pursuant to the Offer a Letter of Instructions
must be submitted by or on behalf of each Holder to the Company at its office at
9 West 57th Street, New York, New York, and the Bonds must be tendered to the
appropriate Exchange Agent at its specified office in Switzerland.  Banque
Scandinave en Suisse, acting through its specified office in Switzerland, has
agreed to provide services as the Exchange Agent with respect to the exchange of
the 8% Bonds due March 1, 1995 (the "8% Bonds") and Bank Leu AG, acting through
its specified office in Switzerland, has agreed to provide services as the
Exchange Agent with respect to the exchange of all Bonds other than the 8%
Bonds. Banque Scandinave en Suisse and Bank Leu AG may be referred to
hereinafter individually as the "Exchange Agent" or, collectively, as the
"Exchange Agents."  The Company will deliver Common Stock to the Exchange Agents
outside the United States, and the Exchange Agents will deliver, on behalf of
the Company, Common Stock pursuant to the Offer only to an account or address
outside the United States.  For purposes of this Offering Circular, the term
"United States" means the United States of America (including the States and the
District of Columbia), its possessions, its territories and other areas subject
to its jurisdiction.

     In order to receive payments pursuant to the Offer without reservation for
backup withholding tax, each exchanging holder of Bonds will be required to
provide and certify its correct taxpayer identification number in the Letter of
Instructions.

     THIS OFFERING CIRCULAR DOES NOT CONSTITUTE AN OFFER OR SOLICITATION IN ANY
STATE OR OTHER JURISDICTION IN WHICH SUCH AN OFFER OR SOLICITATION IS NOT
AUTHORIZED.

     THE SECURITIES OFFERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT, OR THE SECURITIES LAWS OF CERTAIN STATES, AND ARE BEING OFFERED AND SOLD IN
RELIANCE ON EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND SUCH
LAWS.  THE SECURITIES ARE SUBJECT TO RESTRICTION ON TRANSFERABILITY AND RESALE

LAWS PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM.  THE SECURITIES HAVE NOT

STATE SECURITIES COMMISSION OR OTHER REGULATORY AUTHORITY, NOR HAVE ANY OF THE
FOREGOING AUTHORITIES PASSED UPON OR ENDORSED THE MERITS OF THIS OFFERING OR THE
ACCURACY OR ADEQUACY OF THIS OFFERING CIRCULAR.  ANY REPRESENTATION TO THE
CONTRARY IS UNLAWFUL.

     The Offer is being made by the Company in reliance on an exemption from the
registration requirements of the Securities Act, contained in Section 3(a)(9) of
the Securities Act.  In order to be eligible for that exemption, the Company
will not pay any commission or other remuneration to any broker, dealer,
salesman or other person for soliciting tenders of Bonds.  However, regular
employees of the Company (who will not be additionally compensated therefor) may

                                  INTRODUCTION

Description of the Company

     General

     National Patent Development Corporation (the "Company"), incorporated in
Delaware in 1959, is primarily a holding company, which is a legal entity
separate and distinct from its various operating subsidiaries.  The Company's
operations consist of four operating business segments: Physical Science,
Distribution, Optical Plastics and Electronics.  The Company also has an
investment in two companies in the Health Care industry.

     Physical Science

     The Company's Physical Science Group consists of (i) GPS Technologies,
Inc. ("GPS"), an approximately 92% owned subsidiary, and (ii) GTS Duratek, Inc.
("Duratek"), an approximately 66% owned subsidiary.

     GPS provides a wide range of management and technical training as well as
specialized engineering services to various commercial industries and the United
States government. Principal clients of GPS include electric utilities, process
industries, manufacturing plants, Federal agencies and the aerospace industries.
In addition, the Company currently owns approximately a 28% investment in
General Physics Corporation ("General Physics"), which provides a wide range of
personnel training and technical support services to the domestic commercial
nuclear power industry and the United States Departments of Energy and Defense,
as well as environmental engineering, training and support services to
governmental and commercial clients.

     On April 7, 1994, General Physics entered into an agreement with GPS and
the Company to acquire substantially all of the operating assets of GPS and
certain of its subsidiaries.  General Physics agreed to pay GPS a purchase price
with a current present value of approximately $36 million.  The purchase price
will be payable to GPS as follows: $10 million in cash; 3.5 million shares of
General Physics common stock valued at approximately $13,500,000 (based upon the
price per share of General Physics common stock prior to the announcement of the
transaction which was $3.875); warrants to acquire 1,000,000 shares of General
Physics common stock at $6.00 per share valued at approximately $1,300,000;
warrants to acquire up to 475,644 additional shares of General Physics common
stock at $7.00 per share valued at approximately $500,000; and 6% Senior
Subordinated Debentures due 2004 (the "Debentures"), in the aggregate principal
amount of $15,000,000, valued at approximately $10,700,000.  The values assigned
to each component of consideration were based upon (i) discussions with the
independent investment banker to the Independent Committee of General Physics
and the investment banker to GPS and (ii) negotiations between the Independent
Committee of General Physics and the Board of Directors of GPS.  Portions of the
cash and stock consideration of the purchase price will be (a) used to repay
outstanding bank debt of GPS which at March 31, 1994 was $6,350,000 and long-
term debt of GPS which at March 31, 1994 was $8,975,000 to be repaid to the
Company and (b) held in escrow.

     The transaction is contingent upon the occurrence of certain events,
including, without limitation, the approval of the transaction by the
stockholders of General Physics and GPS.  The transaction is anticipated to
close as soon as practicable in the second half of 1994, if all necessary
approvals are obtained and conditions satisfied.  The Company anticipates that,
if the aforementioned transaction is consummated, it will own approximately 52%
of the outstanding common stock of General Physics, and if the Company were to
exercise all of its warrants, it would own approximately 58% of the outstanding
common stock of General Physics.

     Duratek's operations consist of two operating groups: (1) "Environmental
Services" engaged in cleanup of water and other liquids containing radioactive
and/or hazardous (mixed waste) contaminants and minimum additive vitrification
for long-term stabilization of such waste and (2) "Consulting and Staff
Augmentation" services.  Duratek provides services for various utility,
industry, government and commercial clients.

     Distribution

     The Company's Distribution Group, incorporated under the name Five Star
Group, Inc. ("Five Star"), is engaged in the wholesale distribution of home
decorating, hardware and finishing products.

     Healthcare

     The Company's investment in the Health Care industry consists of the
Company's ownership of approximately 36% of the outstanding shares of common
stock of Interferon Sciences, Inc. ("ISI").  ISI is a biopharmaceutical company
engaged in the manufacture and sale of ALFERON N Injection, the only product
approved by the Food and Drug Administration that is based upon a natural
source, multi-species alpha interferon. ISI also is developing its existing
injectable, topical and/or oral formulations of its natural alpha interferon for
the potential treatment of HIV, hepatitis C, hepatitis B, multiple sclerosis,
cancers and other indications.

     Additionally, the Company owns approximately 4.9% of the outstanding
shares of common stock of American White Cross, Inc. (formerly, NPM Healthcare
Products, Inc.) ("White Cross").  White Cross is a leading manufacturer and
marketer of private label adhesive and cotton-based health and personal care
products.

     Optical Plastic

     The Company's Optical Plastics Group, through its wholly owned subsidiary
MXL Industries, Inc., manufactures molded and coated optical products, such as
shields and face masks and non-optical plastic products.

     Electronics

     The Company's Electronics Group, through its subsidiary Eastern
Electronics Mfg. Corporation,  is engaged in contract manufacturing, such as
printed circuit board assembly for the electronics industry.

Recent Developments

     American Drug Company

     On February 2, 1994, the Board of Directors of the Company approved a
dividend of approximately 46.1% of the common stock of American Drug Company to
holders of record of the Company's Common Stock and Class B Capital Stock.
American Drug Company is currently a wholly-owned subsidiary of the Company.
The dividend will be at the rate of one share, plus one warrant to purchase one
share of American Drug Company common stock at an exercise price per share of
$1.00, for every four outstanding shares of Common Stock and Class B Capital
Stock of the Company.  The distribution of American Drug Company common stock to
the Company's stockholders will result in direct ownership in a company focused
on developing markets for American-made generic pharmaceutical and personal care
products in Russia and the other states of the Commonwealth of Independent
States and on developing other business opportunities.  Following the
distribution, the Company will own 6,000,000 shares of the common stock of
American Drug Company, representing approximately 53.9% of the outstanding
common stock of American Drug Company, without accounting for outstanding
options and warrants.

     Interferon Sciences, Inc.

     On May 13, 1994, ISI filed a registration statement with the Commission
relating to a proposed public offering of 3,000,000 shares of its common stock
(with an additional 450,000 shares of its common stock subject to an over-
allotment option).  D. Blech & Company, Incorporated is the underwriter of the
offering.

     The Company is a Delaware corporation, incorporated in 1959, and its
headquarters are located at 9 West 57th Street, New York, New York 10019. Its
telephone number is (212) 230-9500. The Company's Annual Report on Form 10-K for

     Repurchases by the Company

      The Company and its affiliates have repurchased in the open market and
hold SFr. 11,532,000 and US $285,000 of the Bonds.  The Company intends to

     As of March 31, 1994, the Company had an aggregate of $40,469,000 of

is included in current maturities of long-term debt.  For a description of the

     The Company is making the Offer to reduce its long-term indebtedness,
to increase its book value and to provide the Company with additional financial
flexibility in its operations.  See "Purpose of the Offer" and "Capitalization."
Concurrently with the Offer, the Company is making a separate offer on the same
terms and for the same consideration as the Offer to foreign holders of the
Bonds (the "Foreign Offer").  The Company will accept for exchange in the Offer
and the Foreign Offer Bonds representing up to 60% of the aggregate principal
amount outstanding of the Bonds.  As of April 30, 1994, 60% of the aggregate
principal amount outstanding of the Bonds was equal to SFr. 17,900,000, assuming
an exchange rate of 1.4115 with respect to the Old U.S. Dollar Bonds.

Summary Terms and Conditions of the Offer

     Exchange Consideration

     In exchange for each SFr. 1,000 principal amount and each US$ 1,000
principal amount of any of the Bonds validly tendered, the Company offers shares
of its common stock with a par value of US$ 0.01  per share (the "Common Stock")
and with a market value of SFr. 1,000 with respect to Old Swiss Francs Bonds and
of US$ 1,000 with respect to Old U.S. Dollar Bonds.  Interest accrued on the
Bonds up to the Payment Date (as defined

                                     -3-
<PAGE>
 
below) will also be paid in Common Stock.  Fractional shares of Common Stock
resulting from such exchange will be rounded up to the nearest integral
multiple.

     The exchange rate between US$ and Swiss Francs will be determined by
the Exchange Agents on the basis of the Swiss Franc/US$ spot rate reported in
the Wall Street Journal Europe Edition on the fifth trading day prior to July
11, 1994.

     The market value of the Common Stock offered in exchange for the Bonds
will be determined on the basis of the average of the last sale prices on the
American Stock Exchange, Inc. of the Common Stock for the ten (10) trading days
ending five (5) trading days prior to July 11, 1994.

     Offering Period

     The offer to tender the Bonds for exchange is open from June 10, 1994
to July 11, 1994.  The Company reserves the right to extend the Offer for an
additional ten (10) business days, until July 25, 1994.  The date on which the

"Expiration Date."

     Payment Date

     Subject to the conditions set forth in Section 14, the "Payment Date"

     Maximum Acceptance

     Subject to the condition set forth in Section 15, the Company will
accept for exchange Bonds representing up to 60% of the aggregate principal
amount of the outstanding Bonds (the percentage limitation being calculated on
the overall principal amount of all outstanding Bonds, i.e. irrespective of the
individual series of Bonds).  The Company reserves the right to exchange Bonds
representing up to 62% of the aggregate principal amount of the outstanding
Bonds pursuant to the Offer and the Foreign Offer.  In the event Bonds in excess
of 60% of the aggregate principal amount are tendered, the Company may either
(i) accept Bonds tendered on a pro rata basis according to the aggregate
principal amount of all Bonds properly tendered by the Expiration Date or (ii)
amend the terms of the Offer by notice to the holders of the Bonds, in which
case the Offer shall remain open for an additional ten (10) business days from
the date that such notice is first given.  The Company reserves the right to
waive the maximum acceptance restriction.  In no event will the Offer be
extended beyond July 25, 1994.

     Registration of Common Stock

     The Company shall apply for registration of the newly issued shares of
Common Stock with the United States Securities and Exchange Commission (the

to the Common Stock has not been declared effective by the Commission on or
prior to August 15, 1994.

to the exchange of the 8% Bonds due March 1, 1995 (the "8% Bonds") and Bank Leu
AG, acting through its specified office in Switzerland, has agreed to provide
services as the Exchange Agent with respect to the exchange of all Bonds other
than the 8% Bonds. Banque Scandinave en Suisse and Bank Leu AG may be referred
to hereinafter individually as the "Exchange Agent" or, collectively, as the
"Exchange Agents."

     Taxes

     Any securities transfer tax due on the exchange of Bonds for

The Offer

     1. Terms of the Offer.  Upon the terms and subject to
the conditions of the Offer, the Company will accept for exchange Bonds
representing up to 60% of the aggregate principal amount of the outstanding
Bonds which are validly tendered pursuant to the Offer and the Foreign Offer on
or prior to the Expiration Date and not theretofore withdrawn as permitted by
Section 9 of the Offer. The term "Expiration Date" means 5:00 p.m., New York
City time, on July 11, 1994, unless the Company, in its sole discretion, shall
have extended the period of time for which the Offer is open, in which event the
term "Expiration Date" shall mean the latest time and date, not beyond 5:00
p.m., New York City time, on July 25, 1994, at which time the Offer, as so
extended by the Company, shall expire.  The payment date (the "Payment Date")
for Bonds accepted for payment by the Company pursuant to the Offer will be July
25, 1994.  However, if the Company shall have extended the period of time for
which the Offer is open, the Payment Date shall be the tenth (10th) business day
after the adjusted Expiration Date.

     The consideration offered by the Company in exchange for each SFr.
1,000 principal amount of any and all Old Swiss Franc Bonds and each US $1,000
principal amount of any and all Old U.S. Dollar Bonds validly tendered and not
withdrawn prior to the Expiration Date is Common Stock with a market value of
SFr. 1,000, with respect to the Old Swiss Franc Bonds, and of US $1,000, with
respect to the Old U.S. Dollar Bonds.  Interest accrued on the Bonds up to the
Payment Date will be paid in shares of Common Stock of the Company for each SFr.
1,000 principal amount of Old Swiss Franc Bonds (such amounts referred to
collectively as "Swiss Bond Accrued Interest") and for each US $1,000 principal
amount of the Old U.S. Dollar Bonds (such amount referred to as "U.S. Bond
Accrued Interest," and together with the Swiss Bond Accrued Interest, the
"Accrued Interest").  Fractional shares of Common Stock resulting from such
exchange will be rounded up to the nearest integral multiple.

     The Company currently intends to exchange Bonds representing 60% of
the aggregate principal amount of the outstanding Bonds, irrespective of the
individual series of the Bonds, pursuant to the Offer and the Foreign Offer.
The Company reserves the right to exchange Bonds representing up to 62% of the
aggregate principal amount of the outstanding Bonds pursuant to the Offer and
the Foreign Offer.  In the event that Bonds in excess of 60% of the aggregate
principal amount of the outstanding Bonds have been properly tendered by the
holders thereof prior to the Expiration Date and not withdrawn, the Company may,
upon the terms and subject to the conditions of the Offer, either (i) accept
Bonds tendered on a pro rata basis to the holders according to the aggregate
principal amount of all Bonds properly tendered by the Expiration Date and not
withdrawn or (ii) amend the terms of the Offer by notice to the holders of the
Bonds, in which case the Offer shall remain open for an additional ten (10)
business days from the date that such notice is first given.  If not more than
60% in aggregate principal amount of the outstanding Bonds are properly tendered
by the Expiration Date and not withdrawn, all Bonds so tendered and not
withdrawn will, upon the terms and subject to the conditions of the Offer, be
exchanged.  The Company has the right, in its sole discretion, to waive any such
conditions.

     For each SFr. 1,000 principal amount of Old Swiss Franc Bonds
exchanged, the holder will receive Common Stock with a value equal to the sum of
SFr. 1,000 and the respective amount of Swiss Bond Accrued Interest for the
tendered Old Swiss Franc Bond (the "Swiss Bond Common Stock Value").  For each
US $1,000 principal amount of Old U.S. Dollar Bonds exchanged, the holder will
receive Common Stock with a value equal to the sum of US $1,000 and the U.S.
Bond Accrued Interest (the "U.S. Bond Common Stock Value"). The number of shares
of Common Stock issued for each SFr. 1,000 principal amount of Old Swiss Franc
Bonds exchanged will be equal to the number obtained by dividing (i) the Swiss
Bond Common Stock Value by (ii) the Swiss Franc/U.S. Dollar spot rate reported
in The Wall Street Journal-Europe Edition on the fifth trading day prior to July
11, 1994 (as determined by the Company), and then dividing the resulting
quotient by the average of the last sale prices on the American Stock Exchange,
Inc. ("AMEX") of the Common Stock for the ten trading days ending five trading
days prior to July 11, 1994.  The number of shares of Common Stock issued for
each US $1,000 principal amount of Old U.S. Dollar Bonds exchanged will be equal
to the number obtained by dividing (i) the U.S. Bond Common Stock Value by (ii)
the average of the last sale prices on the AMEX of the Common Stock for the ten
trading days ending five trading days prior to July 11, 1994.  Fractional shares
of Common Stock resulting from such exchange will be rounded up to the nearest
integral multiple.

     In recognition of the fact that holders of Common Stock, even though
holding Common Stock for investment, may wish to be legally permitted to sell
their shares of Common Stock when they deem appropriate, the Company has agreed
to prepare and file with the Commission a registration statement with respect to
the resale of the shares of Common Stock from time to time on the AMEX, on the
Pacific Stock Exchange, Inc., in privately-negotiated transactions or otherwise.
In any event, the holders of Common Stock may not sell shares of Common Stock
except (a) in transactions exempt from the registration requirements of the
Securities Act or (b) pursuant to an effective registration statement covering
the Common Stock.

     The Company will use its best efforts to cause the registration
statement to become effective on or before August 1, 1994.  There can, however,
be no assurance that the registration statement will have become effective on
such date.  If such registration statement is not declared effective by the
Commission on or before August 15, 1994, each exchanging holder will have the
option to withdraw the Bonds tendered by it and to renounce its rights to the
Common Stock received for its account in exchange for such Bonds.  Notice of
such withdrawal must be given to the Company prior to August 30, 1994.

     If the Company shall decide, in its sole discretion, to increase the
consideration offered in the Offer or the percentage of Bonds sought in the
Offer beyond 62% and, at the time that notice of such increase is first
published in the manner specified below, the Offer is scheduled to expire
earlier than the tenth (10th) United States business day from, and including,
the date that such notice is first so published in the manner specified below,
then the Offer will be extended until the expiration of such period of ten (10)
United States business days.  For purposes of the Offer, a "United States
business day" means any day other than a Saturday, Sunday or United States
federal holiday and consists of the time period from 12:01 A.M. through 12:00
midnight, New York City time.

     The Company expressly reserves the right (i) to terminate the Offer
and not accept for exchange any Bonds, upon the occurrence of the event
specified in Section 15, by giving notice in writing or by telex of such
termination to the Exchange Agents, and (ii) to amend the Offer at any time, or
from time to time, in any respect other than to decrease the consideration
offered for the Bonds in the Offer.  Any termination, extension or amendment
will be made by public announcement in The Wall Street Journal.
                                       ----------------------- 

     2. Purpose of the Offer.  The purpose of the Offer is to reduce the 
Company's long-term indebtedness and annual interest expense, to increase the 
Company's book value and to provide the Company with additional financial 
flexibility in its operations. In addition, the issuance of the Common Stock 
in the Offer will enable the Company to lower its ratio of long-term debt to 
total capitalization.

     Assuming that 60% of the Bonds had been exchanged on March 31, 1994,
the Company would have reduced its consolidated long-term debt, less current
maturities, from approximately $25,778,000 to approximately $19,914,000 and
increased its book value from approximately $66,158,000 to approximately
$79,292,000.

     3. Investment Considerations.

     (a) Liquidity; Financial Condition. The Company believes that it has
sufficient cash and cash equivalents and borrowing availability under existing
and potential lines of credit to satisfy its cash requirements until the first
scheduled maturity of its Swiss Franc denominated indebtedness on March 1,
1995. However, in order for the Company to meet its long-term cash needs,
which include the repayment of $13,518,000 of Swiss Franc denominated
indebtedness scheduled to mature in 1995 and $7,279,000 of Swiss Franc
denominated indebtedness which is scheduled to mature in 1996, the Company
must obtain additional funds. The Company has reduced and is continuing to
reduce its long-term debt through the issuance of equity securities in
exchange for long-term debt (including the shares of the Company's Common
Stock issued in the Offer), and is also exploring new credit arrangements on
an ongoing basis. However, there is no assurance that the Company will be able
to obtain any new credit arrangements.

     At March 31, 1994, the Company and its majority-owned subsidiaries
held cash and cash equivalents totaling $9,848,000.  Of these amounts,
approximately $7,748,000 is held by the Company and is available for the general
corporate purposes of the Company.

     (b) Recent Historical Operating Losses, Retained Earnings Deficit. Since
1987, the Company has experienced losses before income taxes, discontinued
operations and extraordinary items. These losses were the result of operating
losses at certain of its subsidiaries, which were not wholly offset by
operating profits from certain of its other subsidiaries. The Company's
current strategy is to consolidate certain related operating businesses and to
improve their operating results, while continuing to make investments in new
ventures or make selected divestitures based on market conditions.

     For the quarter ended March 31, 1994, the Company's loss from
operations before income taxes and extraordinary items was $2,394,000, as
compared to a loss of $2,939,000 for the quarter ended March 31, 1993.  For the
year ended December 31, 1993, the Company's loss from operations before income
taxes and extraordinary items was $8,371,000, as compared to a loss of
$13,178,000 for the year ended December 31, 1992.  As of March 31, 1994, the
Company had stockholders' equity of $66,158,000 and a deficit of $41,488,000.
Losses in future years may adversely affect the Company's ability to service its
debt.

     (c) Ratio of Earnings to Fixed Charges. The ratio of earnings to fixed
charges represents the number of times that fixed charges were covered by
income before income taxes, discontinued operations and extraordinary items,
as adjusted by such fixed charges. For the three months ended March 31, 1994
and the year ended December 31, 1993, the Company had a deficiency in the
coverage of fixed charges to earnings before fixed charges of $2,326,000 and
$10,747,000, respectively.

     (d) Holding Company; Dependence on Subsidiaries. The Company is primarily
a holding company, which is a legal entity separate and distinct from its
various operating subsidiaries. As a holding company, the Company is dependent
upon management fees, dividends and other payments or advances from operating
subsidiaries as its principal source of cash to service outstanding debt. The
ability of the Company to obtain cash from an operating subsidiary depends
upon, among other factors, the operating results of the subsidiary,
restrictions on payments to the Company imposed by creditors of the
subsidiary, restrictions on payments to the Company imposed by other
agreements governing the subsidiary and the degree of dilution of dividend
payments resulting from public ownership of equity securities of the
subsidiary.

     As of March 31, 1994, there is currently at the holding company level
approximately $7,748,000 of cash and cash equivalents.  Duratek, under its
Revolving Line of Credit, is prohibited from making any payments to the Company.
GPS, under the terms of its Amended and Restated Revolving Credit and Term Loan
and Security Agreement, may only pay the Company an amount equal to 80% of the
amount GPS would have paid in federal income taxes if it filed its federal
income tax return on a stand-alone basis.  However, GPS may be prohibited from
distributing approximately $1,200,000 of management fees and tax sharing
payments to the Company in 1994 if GPS were to be in violation of certain
covenants in its bank agreements.

                                     -7-
<PAGE>
 
     The rights of the Company and its creditors to participate in the
assets of any of the Company's subsidiaries upon bankruptcy or liquidation of a
subsidiary are subject to the prior claims of the subsidiary's creditors except
to the extent the Company may itself be a creditor with recognized claims
against the subsidiary; however, the Company's claims may be subordinate to the
claims of any secured creditors of the subsidiary.  See "The Company."

     (e) Currency Fluctuations. On March 31, 1994, the value of the Swiss
Franc to the U.S. dollar was approximately 1.412 to 1. At March 31, 1994, the
Company had an aggregate of SFr. 26,318,000 of Swiss Franc denominated
indebtedness outstanding, of which SFr. 23,823,000 represents principal amount
outstanding and SFr. 2,495,000 represents interest accrued thereon. Foreign
currency valuation fluctuations may adversely affect the results of operations
and financial condition of the Company. In order to protect itself against
foreign currency valuation fluctuations, the Company has at times swapped or
hedged a portion of its obligations denominated in Swiss Francs; however, at
March 31, 1994, the Company had not swapped or hedged any of its Swiss Franc
obligations. If the value of the Swiss Franc to the U.S. dollar increases, the
Company will recognize transaction losses on its Swiss Franc obligations.
There can be no assurance that the Company will be able in the future to swap
or hedge obligations denominated in foreign currencies at prices acceptable to
the Company, or at all. The Company will review its policy as to hedging on a
continuing basis.

     (f) Ranking of Common Stock; Certain Bankruptcy Law Considerations.
Consummation of the Offer may have significant bankruptcy consequences for
exchanging holders of Bonds. In general, a note, bond or other evidence of
indebtedness represents a potential bankruptcy claim equal to its face amount,
plus accrued and unpaid interest as of the date of the commencement of the
bankruptcy case, less any unamortized original issue discount. The
determination of original issue discount for bankruptcy purposes may not be
the same as that applicable for tax purposes. Equity securities rank below all
debt claims and claims of holders of common stock rank below claims of holders
of preferred stock. Accordingly, exchanging holders will have a bankruptcy
claim that ranks below the claims of all remaining holders of Bonds, as well
as $16,006,000 of other long-term indebtedness less current maturities at
March 31, 1994.

     4. Risks to Non-Exchanging Holders. Holders of the Bonds who do not
participate in the Offer may be subject to certain adverse consequences.

     The purchase of Bonds pursuant to the Offer will reduce the aggregate
principal amount of Bonds that might otherwise trade publicly, will reduce the
number of holders of Bonds and could adversely affect the liquidity and market
value of the remaining Bonds held by the public. A debt security with a
smaller float may command a lower price than a comparable debt security with a
greater float. Therefore, the market price for a Bond may be adversely
affected to the extent that the principal amount of the Bonds tendered
pursuant to the Offer reduces the float of the Bonds. This reduced float may
also tend to make the trading price more volatile.

     5. Price Range of the Bonds. The Bonds are traded in Switzerland on the
Stock Exchanges of Zurich, Basle and Geneva. The following table sets forth
the range of high and low sale prices of each of the classes of Bonds in
percentages of principal amount as reported by the Zurich Stock Exchange for
the periods set forth below:

  7.  Acceptance for Exchange and Payment. Upon the terms and subject to the
condition to acceptance for exchange set forth in Section 15 and the other
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the Company will
accept for exchange up to 60% of the aggregate principal amount outstanding of
the Bonds validly tendered on or prior to the Expiration Date and not properly
withdrawn as permitted by Section 9.  In the event that Bonds in excess of 60%
of the aggregate principal amount of the outstanding Bonds have been properly
tendered by the Expiration Date and not withdrawn, the Company may, upon the
terms and subject to the conditions of the Offer, either (i) accept Bonds
tendered on a pro rata basis according to the aggregate principal amount of all
Bonds properly tendered by the Expiration Date and not withdrawn or (ii) amend
the terms of the Offer by notice to holders of the Bonds, in which case the
Offer shall remain open for an additional ten (10) business days from the date
that such notice is first given.  If not more than 60% in aggregate principal
amount of the Bonds are properly tendered by the Expiration Date and not
withdrawn, all Bonds so tendered and not withdrawn will, upon the terms and
subject to the conditions of the Offer, be exchanged.

  Subject to the conditions set forth in Section 14, the Payment Date for 
Bonds accepted for payment by the appropriate Exchange Agent will be July 25,
1994, provided, however, if the Company shall have extended the period of time
for which the Offer is open, the Payment Date shall be the tenth (10th) business
day after the Expiration Date of the Offer. The term "Expiration Date" means
5:00 p.m., New York City time, on July 11, 1994, unless the Company in its sole
discretion shall have extended the period of time for which the Offer is open,
in which event the term "Expiration Date" shall mean the latest time and date,
not beyond 5:00 p.m., New York City time on July 25, 1994 at which time the
Offer, as so extended by the Company, shall expire. In all cases, payment for
Bonds exchanged pursuant to the Offer will be made only upon timely receipt by
the Company at its office in New York of the Letter of Instructions and by the
appropriate Exchange Agent at its specified office in Switzerland of such Bonds,
together with any and all unmatured and matured but unpaid coupons. In the event
that unmatured and matured but unpaid coupons are not submitted with Bonds
tendered, such Bonds will not be accepted for tender. The respective amount of
Swiss Bond Accrued Interest will be paid on the Old Swiss Franc Bonds and the
U.S. Bond Accrued Interest will be paid on the Old U.S. Dollar Bonds, all to be
paid in the Company's Common Stock. Tenders of Old Swiss Franc Bonds will be
accepted only in principal amounts of SFr. 1,000 and integral multiples thereof
and tenders of Old U.S. Dollar Bonds will be accepted only in principal amounts
of US $1,000 and integral multiples thereof. If fractional Bonds result from
proration, such fractions shall be rounded up to the nearest integral multiple
of SFr. 1,000 or US $1,000, as the case may be.

  For purposes of the Offer, the Company shall be deemed to have accepted 
for exchange tendered Bonds on the Expiration Date, provided that the condition
to the Offer set forth in Section 15 has been waived or satisfied, unless it
gives notice to the contrary to the Exchange Agents and by publication in The
                                                                          ---  
Wall Street Journal no later than five (5) business days after the Expiration
- -------------------
Date. Payment for Bonds so accepted for exchange will be made on the Payment
Date, unless the conditions set forth in Section 14 have not been waived or
satisfied, by delivery of the stock certificates representing the Common Stock
to the Exchange Agents at their specified offices in Switzerland.

  If any tendered Bonds are not exchanged for any reason, the Exchange 
Agents will return the Bonds tendered to the holder thereof without expense to
the tendering bondholder as promptly as practicable after the expiration or
termination of the Offer.

  8.  Procedures for Tendering Bonds.  In order to exchange Bonds validly
pursuant to the Offer, a Letter of Instructions for acceptance of the Offer must
be submitted by or on behalf of each beneficial owner of Bonds to the Company at
its office in New York and such Bonds must be submitted to the appropriate
Exchange Agent at its specified office in Switzerland.  Any financial
institution holding Bonds on behalf of one or more beneficial owners may submit
one Letter of Instructions for all such beneficial owners.  Tenders on behalf of
bondholders will be valid only if received by the appropriate Exchange Agent
prior to the Expiration Date.

  Except as set forth below, all questions as to the validity, form and
eligibility (including time of receipt) of any tendered Bonds pursuant to any of
the procedures described above will be determined in the sole discretion of the
Company, whose decision will be final and binding. The Company reserves the
absolute right to reject any or all tenders of any Bonds determined by it not to
be in proper form or if the acceptance of or payment for such

                                     -16-
<PAGE>
 
Bonds may, in the opinion of the Company's counsel, be unlawful or result in
adverse tax consequences to the Company.  The Company also reserves the absolute
right to waive any of the conditions of the Offer or any defect or irregularity
in any tender with respect to Bonds of any particular bondholder and the
Company's interpretation of the terms and conditions of the Offer will be final
and binding.  The Company will be under no duty to give notification of any
defect or irregularity in tender and shall not incur any liability for failure
to give any such notification.

  9.  Withdrawal Rights.  Except as stated in this Section 9, tenders of Bonds
made pursuant to the Offer are irrevocable. Bonds tendered pursuant to the Offer
may be withdrawn at any time prior to the Expiration Date.

  For a withdrawal to be effective, a written, telegraphic, telex or facsimile
transmission notice of withdrawal must be timely sent or delivered by or on
behalf of the bondholder to the appropriate Exchange Agent and received by the
appropriate Exchange Agent prior to the Expiration Date.  Any such notice of
withdrawal must specify the name of the bank having tendered on behalf of the
bondholder, the Bonds to be withdrawn and the aggregate principal amount of
Bonds to be withdrawn.  Withdrawals may only be made in principal amounts of
SFr. 1,000 or integral multiples thereof in the case of the Old Swiss Franc
Bonds or US $1,000 or integral multiples thereof in the case of the Old U.S.
Dollar Bonds.  Bonds tendered pursuant to the Offer may also be withdrawn after
the Expiration Date if the registration statement of the Company with respect to
the Common Stock has not been declared effective by the Commission on or prior
to August 15, 1994.

  All questions as to validity (including time of receipt) of notices of
withdrawal will be determined by the appropriate Exchange Agent, in its sole
discretion, which determination will be final and binding.  The Company will not
be under any duty to give notification of any defect or irregularity in any
notice of withdrawal and shall not incur any liability for failure to give any
such notification.

  Withdrawals of Bonds may not be rescinded, and any Bonds withdrawn will
thereafter be deemed not validly tendered for purposes of the Offer. However,
withdrawn Bonds may be returned at any subsequent time prior to the Expiration
Date by again following the procedures described in Section 8.

  10.  Certain Federal Income Tax Consequences.

  The following is a summary of certain United States federal income tax
considerations that may be relevant to a holder of Bonds that is a United States
person or that otherwise is subject to United States federal income taxation on
a net income basis in respect of Bonds (a "United States holder").  For this
purpose, a "United States person" is a citizen or resident of the United States,
a corporation, partnership or other entity created or organized in or under the
laws of the United States or any political subdivision thereof or an estate or
trust the income of which is subject to United States federal income taxation
regardless of its source.

  The summary is based upon the current provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), and upon regulations, rulings and judicial
decisions now in effect (or, in the case of certain regulations, now in proposed
form), all of which are subject to change.  The summary deals only with United
States holders that hold Bonds, and that will hold Common Stock, as capital
assets (within the meaning of Section 1221 of the Code), and does not address
tax considerations that may be relevant to a United States holder that is
subject to special tax rules under the Code, such as banks, insurance companies,
tax-exempt organizations, dealers in securities or currencies, regulated
investment companies, persons that hold Bonds, or that will hold Common Stock,
as a hedge against currency risks or as a position in a "straddle" for tax
purposes or persons that have a "functional currency" other than the U.S.
dollar.

  Substantial uncertainties exist with respect to the United States federal
income tax consequences of the Offer, and no ruling has been or will be
requested from the Internal Revenue Service (the "Service") on any aspect of the
Offer.  Further, the discussion herein is not binding on the Service.
Accordingly, no assurances can be given with respect to the United States
federal income tax consequences of the Offer.  Each United States holder of
Bonds is urged to consult its own tax advisor in determining the specific tax
consequences to such holder of the Offer, including the application to its
particular situation of the tax considerations discussed below, as well as the
application of state, local or other tax laws.

                                     -17-

The Exchange

  In General.  The Company believes that the exchange (the "Exchange") of Bonds
  ----------                                                                   
for Common Stock will constitute a reorganization and recapitalization (within
the meaning of Section 368(a)(1)(E) of the Code).

  The Exchange will be treated as a recapitalization to United States holders of
the Bonds only if the Bonds are treated as "securities" for purposes of the
reorganization provisions of the Code.  The Company intends to take the position
for all federal income tax purposes that all of the Bonds constitute securities.
However, because the term "securities" is not defined in the Code or in the
regulations promulgated thereunder, and the applicable judicial decisions are
not entirely consistent, there can be no assurance that the Service or a court
will agree with the position taken by the Company.

  If the Bonds that a United States holder surrenders in the Exchange are not
treated as securities, then the Exchange will be treated as a taxable
transaction, rather than as a recapitalization.  In such a case, in general, an
exchanging United States holder will recognize gain or loss in an amount equal
to the difference between the fair market value of the Common Stock received by
such holder and the adjusted tax basis of the Bonds exchanged therefor in the
hands of the United States holder.  United States holders of Bonds should
consult their own tax advisors with respect to the federal income tax
considerations arising from treatment of the Exchange as a taxable transaction.
Except as specifically noted otherwise, the remainder of this summary assumes
that the Exchange will be treated as a recapitalization and that all of the
Bonds will be treated as securities.

  Old U.S. Dollar Bonds.  The treatment of the Exchange to a United States
  ---------------------                                                   
holder of Old U.S. Dollar Bonds is complicated by uncertainty as to the basic
tax treatment of the Old U.S. Dollar Bonds.  Under proposed regulations, which
are proposed to be effective only for "transactions" entered into on or after
the date on which the regulations are finalized (the "Proposed Foreign Currency
Regulations"), each Old U.S. Dollar Bond would be considered for federal income
tax purposes to be split into its two currency components.  In particular, the
principal amount of an Old U.S. Dollar Bond would be treated as a U.S. dollar-
denominated zero-coupon bond (the "Constructive Zero Coupon Bond") and the
interest payments on the Old U.S. Dollar Bond would be treated as a Swiss Franc-
denominated level-payment installment note (the "Constructive Installment
Note").  The issue price of the Constructive Zero Coupon Bond would be
determined by discounting the principal amount of the Old U.S. Dollar Bond at a
yield appropriate for dollar-denominated zero coupon obligations issued by the
Company; the "principal amount" of the Constructive Installment Note would be
the difference between the principal amount of the Old U.S. Dollar Bond and the
issue price of the Constructive Zero Coupon Bond.  Under this bifurcation
approach, it appears that a subsequent holder of an Old U.S. Dollar Bond would
allocate its purchase price between the Constructive Zero Coupon Bond and the
Constructive Installment Note by reference to their relative fair market value
at the purchase date.

  The Proposed Foreign Currency Regulations do not make it clear whether the
bifurcation approach is intended to apply for all federal income tax purposes.
It is clear that the bifurcation approach is intended to apply for purposes of
the original issue discount provisions of the Code and for purposes of the
foreign currency rules contained in Section 988 of the Code.  It is less clear
whether the bifurcation approach should apply for purposes of computing the gain
or loss realized by a United States holder on the Exchange (so that an
exchanging United States holder of an Old U.S. Dollar Bond would realize gain or
loss separately with respect to the Constructive Zero Coupon Bond and the
Constructive Installment Note and would be required to allocate its amount
realized between the Constructive Zero Coupon Bond and the Constructive
Installment Note).  It is also unclear whether the bifurcation approach is
intended to apply for purposes of the reorganization provisions of the Code (so
that one component of an Old U.S. Dollar Bond might fail to qualify as a
security) or for other collateral purposes.

  The bifurcation approach adopted in the Proposed Foreign Currency Regulations
(i) has been criticized as wrong in theory and unworkable in practice and (ii)
in any event, as noted above, is proposed to be effective only for transactions
entered into on or after the publication of final regulations.  To date, the
Company has treated the Old U.S. Dollar Bonds as unitary obligations issued with
[$132] of original issue discount per $1,000 of principal amount, and has
accounted for the Swiss Franc-denominated interest payments in accordance with
the usual rules under Section 988 (as to which, see "Tax Consequences of the
Exchange" below).  At present, the Company intends

                                     -18-
<PAGE>
 
to continue this treatment.  United States holders of Old U.S. Dollar Bonds are
urged to consult their own tax advisors.

  Tax Consequences of the Exchange.  If the Exchange is treated as a
  --------------------------------                                  
recapitalization, then, except as discussed below under "Accrued Interest on
Bonds", the Exchange should have the following federal income tax consequences:

  1.  An exchanging United States holder will realize an overall gain or loss on
the Exchange, in an amount equal to the difference between (i) the fair market
value of the Common Stock received by such United States holder (other than
Common Stock received in respect of accrued interest on the Bonds) and (ii) the
adjusted tax basis of the Bonds in the hands of such United States holder.  Gain
realized by a United States holder on the Exchange will be recognized to the
extent discussed below with respect to Section 988 of the Code.  Except as
discussed below with respect to Section 988 of the Code, loss realized by a
United States holder on the Exchange may not be recognized.

  2.  It appears that the accrued market discount, if any, on a Bond in the
hands of an exchanging United States holder will carry over to the Common Stock
received by the United States holder in the Exchange.  See "Common Stock-- Sale
or Exchange" below.  For this purpose, in general, the aggregate amount of
market discount on an Old Swiss Franc Bond in the hands of an exchanging United
States holder is the excess, if any, determined in Swiss Francs, of (i) the
stated redemption price at maturity of the Old Swiss Franc Bond over (ii) the
tax basis of the Old Swiss Franc Bond in the hands of the exchanging United
States holder immediately after its acquisition.  In general, such market
discount accrues on a straight-line basis from the date of acquisition of the
Old Swiss Franc Bond by the United States holder over the remaining term of the
Old Swiss Franc Bond; the U.S. dollar amount of accrued market discount on the
Old Swiss Franc Bond as of the exchange date will be determined by translating
the portion of the Swiss Franc market discount that has accrued as of the
exchange date into U.S. dollars at the spot exchange rate on the exchange date.

  In the case of the Old U.S. Dollar Bonds, under the bifurcation approach
adopted in the Proposed Foreign Currency Regulations, a United States holder
presumably would determine market discount separately with respect to the
Constructive Zero Coupon Bond and the Constructive Installment Note.
Presumably, the amount of market discount on each portion of an Old U.S. Dollar
Bond in the hands of an exchanging United States holder would be the excess, if
any, determined in the applicable currency, of (i) the "revised issue price" of
such portion over (ii) the tax basis of such portion in the hands of the
exchanging United States holder immediately after its acquisition.  For this
purpose, the "revised issue price" of each portion of the Old U.S. Dollar Bond
should be the issue price of such portion, plus the aggregate amount of original
issue discount accrued on such portion for periods prior to the acquisition of
the Old U.S. Dollar Bond by the United States holder and less all payments made
on such portion  prior to such acquisition.  The market discount on the
Constructive Installment Note would be computed in Swiss Francs, would accrue
under the special rules for installment obligations (under which, in general,
the portion of the aggregate market discount that accrues in any period is
determined by reference to the ratio that the original issue discount accruing
in the period bears to aggregate original issue discount) and would be
translated into U.S. dollars at the spot exchange rate on the exchange date.

  3.  The foreign currency rules contained in Section 988 of the Code may affect
the amount and character of gain or loss recognized by a United States holder on
the Exchange.

  The regulations under Section 988 provide that upon the exchange of a foreign
currency-denominated debt instrument for stock of the obligor, any gain or loss
realized by the exchanging holder on the exchange generally must be recognized
and treated as ordinary income or loss, to the extent of the foreign currency
gain or foreign currency loss realized by the holder with respect to the
principal amount of, and any accrued interest on, the debt instrument.
Accordingly, it appears that to the extent that a United States holder realizes
but does not otherwise recognize gain or loss on the Exchange, that gain or loss
will be recognized and treated as ordinary income or loss, to the extent of the
foreign currency gain or the foreign currency loss, respectively, realized by
the United States holder on the Exchange.

                                     -19-
<PAGE>
 
  For purposes of the foregoing rules, in general, the amount of foreign
currency gain or loss realized by a United States holder with respect to the
"principal amount" of an Old Swiss Franc Bond will be determined by (i)
translating the principal amount into U.S. dollars at the spot rate on the date
of the Exchange and (ii) subtracting from that amount the amount computed by
translating the principal amount into U.S. dollars at the spot rate on the date
that the United States holder acquired the Old Swiss Franc Bond.  For this
purpose, the principal amount of an Old Swiss Franc Bond will be the purchase
price of the Old Swiss Franc Bond in Swiss Francs.  In addition, the United
States holder may realize foreign currency gain or loss with respect to any
interest (including original issue discount) accrued by the United States holder
prior to, and received by the United States holder in connection with, the
Exchange.  Notwithstanding any of the general rules described above, however,
the aggregate foreign currency gain realized by a United States holder on the
Exchange may not exceed the total gain, if any, realized on the Exchange;
similarly, the aggregate foreign currency loss realized by a United States
holder on the Exchange may not exceed the total loss, if any, realized on the
Exchange.

  As discussed above, the tax treatment of the Old U.S. Dollar Bonds is unclear
in various respects.  Under the bifurcation approach adopted in the Proposed
Foreign Currency Regulations, only the Constructive Installment Note
(representing the interest payments on the Old U.S. Dollar Bonds) would be
subject to Section 988.

  4.  The tax basis of the Common Stock (other than Common Stock received in
respect of accrued interest) in the hands of an exchanging United States holder
will equal the adjusted tax basis of the Bonds transferred in the Exchange,
increased by any gain and, presumably, decreased by any loss recognized on the
Exchange.  The holding period of the Common Stock (other than Common Stock
received in respect of accrued interest) generally should include the period
during which the exchanging holder held the Bonds transferred in the Exchange.

  Accrued Interest on Bonds.  Under Section 354(a)(2)(B) of the Code, it appears
  -------------------------                                                     
that an exchanging United States holder will recognize ordinary income or loss
on the Exchange, in an amount equal to the difference between (i) the portion of
the Common Stock received that is attributable to the claim of the United States
holder for accrued interest on the Bonds surrendered and (ii) the amount, if
any, of such accrued interest that the United States holder, under its
accounting method, has previously included in income, regardless of whether such
United States holder realizes an overall gain or loss on the Exchange.  As
discussed above, under Section 988 of the Code, the United States holder may
recognize foreign currency gain or loss with respect to accrued interest or
accrued original issue discount on the Bonds.

Common Stock.

  Dividends.  Distributions, if any, paid on the Common Stock, to the extent
  ---------                                                                 
made from the current or accumulated earnings and profits of the Company, as
determined for federal income tax purposes, will be included in income by a
United States holder when paid.

  Sale or Exchange.  Upon the sale or exchange of Common Stock, a United States
  ----------------                                                             
holder will recognize gain or loss in an amount equal to the difference between
(i) the amount of cash and the fair market value of the property received and
(ii) the adjusted tax basis of the Common Stock in the hands of the United
States holder.  Such gain or loss generally will be treated as capital gain or
loss, except that such gain will be treated as ordinary income to the extent of
any market discount carried over to the Common Stock (see "The Exchange -
General" above).

Non-Exchanging United States Holders of Bonds

  The Offer and the Foreign Offer will have no federal income tax consequences
to United States holders of Bonds that do not participate in the Offer.

  11.  Fees and Expenses.  The Company is not paying any fees for soliciting the
exchange of the Bonds in the Offer.  However, assuming that 60% of the Bonds are
tendered for exchange, total fees and expenses of the Offer and the Foreign
Offer, including legal, accounting and printing fees, are not expected to exceed
[$500,000].

                                     -20-
<PAGE>
 
  Requests for additional information or additional copies of this Offering
Circular should be directed to the Company.

  12.  Exchange Agents.  Banque Scandinave en Suisse, acting through its
specified office in Switzerland, will serve as Exchange Agent with respect to
the exchange of the 8% Bonds, and Bank Leu AG, acting through its specified
office in Switzerland, will serve as Exchange Agent with respect to all other
Bonds. BANQUE SCANDINAVE EN SUISSE and BANK LEU AG may be referred to
individually as the "Exchange Agent" or, collectively, as the "Exchange Agents."

  Each Exchange Agent will receive a fee equal to 3.5% of the aggregate
principal amount of all Bonds tendered for exchange pursuant to the Foreign
Offer, not this Offer, plus a bonus if the aggregate amount of Bonds tendered
reaches certain thresholds.  In addition, the Exchange Agents will be reimbursed
for their costs and expenses.

  Assuming that 60% of the Bonds are tendered for exchange, total fees and
expenses of the Offer, including legal, accounting, investment, banking
presentation and printing fees, are not expected to exceed approximately SFr.
1,180,000 based on the April 30, 1994 exchange rate of 1.4115.

     13.  Description of Common Stock.

     Description of Common Stock.

     As of May 12, 1994 the Company had outstanding two classes of common stock:
20,310,706 shares of Common Stock, par value $.01 per share, entitled to one
vote per share on all matters, and 250,000 shares of Class B Capital Stock, par
value $.01 per share ("Class B Stock"), entitled to ten votes per share on all
matters, without distinction between classes except when approval of a majority
of each class is required by statute. The Class B Stock is convertible at any
time into shares of Common Stock on a share for share basis.

     Since the Common Stock and Class B Stock do not have cumulative voting
rights, the holders of shares having more than 50% of the voting power, if they
choose to do so, may elect all the directors of the Company and the holders of
the remaining shares would not be able to elect any directors.

     The holders of Common Stock and Class B Stock are entitled to share equally
in any dividends (other than stock dividends) that may be declared, and if any
stock dividends are declared, they are to be declared and paid at the same rate
on each class of stock in the shares of such class. In the event of liquidation,
dissolution or winding up of the Company, the holders of the Common Stock and
Class B Stock are entitled to share equally, share and share alike, in the
corporate assets available for distribution to stockholders. None of the shares
of either class has any preemptive or redemption rights or sinking fund
provisions applicable to it, and all the presently outstanding shares are fully
paid and nonassessable.

     14.  Certain Conditions of the Offer.  Notwithstanding any other provision
of the Offer, the Company shall not be required to pay for Bonds on the Payment
Date, and may, in its sole discretion, terminate the Offer if on or after the
Expiration Date of the Offer, and prior to the time of payment for any Bonds
tendered, any of the following events shall occur:

          (a)  there shall be threatened, instituted or pending any action,
     proceeding or application by or before any court or governmental agency or
     other regulatory or administrative agency or commission, in the United
     States or elsewhere, by any government or governmental authority or other
     regulatory agency or commission in the United States or elsewhere, or by
     any other person, (i) challenging the exchange by the Company of Bonds
     pursuant to the Offer (or the Foreign Offer) or seeking to restrain or
     prohibit the consummation of the transactions contemplated by the Offer (or
     the Foreign Offer) or seeking to obtain any material damages or otherwise
     directly or indirectly relating to the transactions contemplated by the
     Offer (or the Foreign Offer), (ii) making, or seeking to make, the exchange
     of, or payment for, some or all of the Bonds pursuant to the Offer illegal
     or resulting in a delay in the ability (including the Foreign Offer) of the
     Company to accept for payment or pay for some or all of the Bonds, or
     making

                                     -21-
<PAGE>
 
     consummation of the Offer unduly burdensome to the Company, (iii) imposing,
     or seeking to impose, material limitations on the ability of the Company
     effectively to acquire or hold or to exercise full rights of ownership of
     the Bonds acquired by it, (iv) which, in any event, in the reasonable
     judgment of the Company, adversely affect, or may adversely affect, the
     Company or any of its subsidiaries, or the value of the Bonds or (v) which,
     in the reasonable judgment of the Company might result in a material
     limitation in the benefits expected to be derived by the Company as a
     result of the transactions contemplated by the Offer (or the Foreign
     Offer); or

          (b)  there shall be any action taken, or proposed or threatened, or
     any statute, rule, regulation, judgment, order or injunction (preliminary
     or permanent) proposed, sought, enacted, promulgated, entered, enforced or
     deemed applicable to the Offer (or the Foreign Offer), by any government,
     governmental authority or other regulatory or administrative agency or
     commission or court, in the United States or elsewhere, that, in the sole
     judgment of the Company, might, directly or indirectly, result in any of
     the consequences referred to in clauses (i) through (v) of paragraph (a)
     above; or

          (c)  there shall have occurred (i) any general suspension of, or
     limitation on prices for, trading in securities on any United States
     national securities exchange or in the over-the-counter market or on any
     Swiss national securities exchange or over-the-counter market, (ii) the
     declaration of a banking moratorium or any suspension of payments in
     respect of banks in Switzerland or in the United States, (iii) the
     commencement of a war, armed hostilities or other international or national
     calamity directly or indirectly involving the United States or Switzerland,
     (iv) any limitation by any governmental agency (whether or not mandatory)
     on, or any other event which, in the sole judgment of the Company, might
     affect the extension of credit by banks or other lending institutions, (v)
     a suspension of, or limitation on, the free marketability or convertibility
     of the currency of the United States and/or Switzerland or (vi) in the case
     of any of the foregoing existing at the time of the commencement of the
     Offer (or the Foreign Offer), a material acceleration or worsening thereof.

     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition (including any action or inaction by the Company) or may be waived by
the Company in whole or in part at any time and from time to time in its sole
discretion. The failure by the Company at any time to exercise any of the
foregoing rights shall not be deemed a waiver of any such right and each such
right shall be deemed an ongoing right and may be asserted at any time and from
time to time. Any determination by the Company concerning the events described
in this Section 13 will be final and binding upon all parties.

     15.  Condition to Acceptance for Exchange.  Notwithstanding any other
provision of the Offer, the Company shall not be required to accept Bonds for
exchange on the Expiration Date, and may, in its sole discretion, terminate the
Offer if on the Expiration Date the average of the last sale prices on the AMEX
of the Common Stock for the ten (10) trading days ending five (5) trading days
prior to the Expiration Date is less than $3.00.  The foregoing condition is for
the sole benefit of the Company and may be asserted by the Company regardless of
the circumstances giving rise to any such condition (including any action or
inaction by the Company) or may be waived by the Company in whole or in part at
any time and from time to time in its sole discretion. The failure by the
Company at any time to exercise any of the foregoing rights shall not be deemed
a waiver of any such right and each such right shall be deemed an ongoing right
and may be asserted at any time and from time to time. Any determination by the
Company concerning the events described in this Section 14 will be final and
binding upon all parties.

     16.  Miscellaneous.  The Offer is not being made to (nor will tenders of
Bonds be accepted from or on behalf of) holders of Bonds in any jurisdiction in
which the Offer or the acceptance thereof would not be in compliance with the
securities or other laws of such jurisdiction.

     No person has been authorized to give any information or make any

Item 1.  Business
         --------

           (a)  General Development of Business 

         National Patent Development Corporation (the "Company"), incorporated 
in Delaware in 1959, is primarily a holding company, which is a legal entity
separate and distinct from its various operating subsidiaries. The Company's
operations consist of four operating business segments: Physical Science,
Distribution, Optical Plastics and Electronics. The Company also has an
investment in two companies in the Health Care industry.

         The Company's Physical Science Group consists of (i) GPS Technologies, 
Inc. ("GPS"), an approximately 92% owned subsidiary and (ii) GTS Duratek, Inc. 
("Duratek"), an approximately 66% owned subsidiary.

         GPS provides a wide range of management and technical training as
well as specialized engineering services to various commercial industries and
the United States government. Principal clients of GPS include electric
utilities, process industries, manufacturing plants, Federal agencies, and the
aerospace industries. In addition, the Company currently owns approximately a
28% investment in General Physics Corporation ("General Physics"), which
provides a wide range of personnel training and technical support services to
the domestic commercial nuclear power industry, United States Departments of
Energy and Defense, as well as environmental engineering, training and support
services to governmental and commercial clients.

         Duratek's operations consist of two operating groups: (1) 
"Environmental Services" engaged in cleanup of water and other liquids
containing radioactive and/or hazardous (mixed waste) contaminants and minimum
additive vitrification for long-term stabilization of such waste, and
(2) "Consulting and Staff Augmentation" services. Duratek provides services for
various utility, industry, government and commercial clients.

         The Company's Distribution Group, incorporated under the name Five Star
Group, Inc. ("Five Star"), is engaged in the wholesale distribution of home
decorating, hardware and finishing products.

         The Company's Health Care Group consists of an approximately 36%
investment in Interferon Sciences, Inc. ("ISI"). ISI is a biopharmaceutical
company engaged in the manufacture and sale of ALFERON N Injection and the
research and development of other uses of ALFERON N Injection and other alpha
interferon-based formulations for the treatment of certain viral diseases,
cancers, and diseases of the immune system.

         The Company currently owns approximately a 14% investment in American
White Cross, Inc. (formerly, NPM Healthcare Products, Inc., "White Cross"). 
White Cross is a 
<PAGE>
 
leading manufacturer and marketer of private label adhesive and cotton based 
health and personal care products.

         The Company's Optical Plastics Group, through its wholly owned
subsidiary MXL Industries, Inc. ("MXL") manufactures molded and coated optical
products, such as shields and face masks and non-optical plastic products.

         The Company's Electronics Group, through its subsidiary Eastern 
Electronics Mfg. Corporation is engaged in contract manufacturing, such as
printed circuit board assembly for the electronics industry.

         Certain financial information about business segments (classes of
similar products or services) is included in Note 17 of Notes to Consolidated
Financial Statements.

         (c)  Narrative Description of Business

RECENT DEVELOPMENTS

GENERAL PHYSICS CORPORATION AND
GPS TECHNOLOGIES, INC. PROPOSED TRANSACTION
- -------------------------------------------

         On January 13, 1994, General Physics signed a Letter of Intent with 
GPS and the Company to acquire substantially all of the operating assets of
GPS and certain of its subsidiaries. The Company currently owns approximately
92% of the outstanding common stock of GPS and approximately 28% of the
outstanding common stock of General Physics. On March 28, 1994 the Board of
Directors of both GPS and General Physics approved the transaction. The
parties are currently negotiating the terms of a definitive agreement and the
transaction is anticipated to close as soon as practicable in the second half
of 1994, if all necessary approvals are obtained and conditions satisfied.

         The purchase price has a current present value of approximately $36
million based on current market prices.  The purchase price will be payable to
GPS as follows:  $10 million cash; 3.5 million shares of General Physics common
stock valued at approximately $13,500,000 (based upon the price per share of
General Physics common stock prior to the announcement of the transaction which
was $3.875); warrants to acquire 1,000,000 shares of General Physics common
stock at $6.00 per share valued at approximately $1,300,000; warrants to acquire
up to 475,644 additional shares of General Physics common stock at $7 per share
valued at approximately $500,000; a $15 million ten-year senior subordinated
debenture (the "Debentures") valued at approximately $10,700,000, accruing
interest at 6% per annum, interest payable only for the first five years, with
70% of principal payable in equal quarterly installments during the remaining
five years until maturity.  The values assigned to each component of
consideration were based upon discussions with the 

                                      2
<PAGE>
 
independent investment banker to the Independent Committee of General Physics
and the investment banker to GPS. Portions of the cash and stock consideration
of the purchase price will be (a) used to repay outstanding bank debt of
$5,650,000 (as of December 31, 1993) and long-term debt of GPS of $8,809,000
(as of December 31, 1993) to be repaid to the Company. In addition $1.5
million of Debentures are held in escrow for the benefit of General Physics in
connection with certain indemnification obligations.

        The transaction was recommended by an Independent, Committee of General
Physics' Board of Directors and was approved by the Board of Directors of both
General Physics and GPS and is contingent upon the occurrence of certain
events, including, without limitation: approval of the transaction by the
stockholders of both General Physics and GPS.

        The Company anticipates that if the aforementioned transaction is
consummated, it will own approximately 52% of the outstanding common stock of
General Physics, and if the Company were to exercise all of its warrants, it
will own approximately 58% of the outstanding common stock of General Physics.

        Although an agreement in principle has been reached, there   can be no
assurance that a definitive agreement will be successfully negotiated and
signed, or that the transaction will close as anticipated.

GTS DURATEK, INC.
- -----------------

General

        GTS Duratek, Inc. ("Duratek") was incorporated in the State of Delaware 
in December 1982. At December 31, 1993 Duratek was an approximately 66%
controlled subsidiary of the Company.

        Duratek's operations consist of two operating groups: (i) 
"Environmental Services", engaged in cleanup of water and other liquids 
containing radioactive and/or hazardous (mixed waste) contaminants and 
in-furnance vitrification for long-term stabilization of such waste, and (ii)
"Consulting and Staff-Augmentation" services. Duratek provides services for
various utility, industry, government and commercial clients.

        During 1992, Environmental Services received a U.S. Department of Energy
("DOE") funded contract called MAWS for minimum additive waste stabilization.
This agreement enabled Environmental Services to further develop its
vitrification technology being used for processing actual mixed waste in a
demonstration at the DOE's Fernald facility.

        During 1993 Duratek designed, constructed and operated a 300
kilogram per day vitrification melter ("Duramelter") at Fernald under the
first phase of the MAWS project and began the second phase requiring
processing of actual mixed waste through the melter that it designed and built
at Fernald under varying controlled operating conditions. During 1993, Duratek
was also awarded a $1.2 million contract to study the chemical composition of
waste streams at DOE sites across the country to determine their suitability
for conversion into glass using the MAWS technology. Additionally, at the end
of 1993 Duratek was awarded a $13.9 million three year contract to stabilize
700,000 gallons of mixed waste sludges at the DOE's Savannah River nuclear
weapons production site. This project is Duratek's first commercial scale
project using its vitrification technology to convert the nuclear weapons 
by-product waste materials into glass for long term stabilization and storage.

        Consulting and Staff Augmentation revenues decreased by 12% due to 
lower utilization of contract services by its commercial nuclear power
customers.  This decrease resulted from an overall effort by electric utilities
to reduce operating costs in response to competitive pressures to become low
cost producers of electric power.  The group continued to provide support to
Duke Power, Vermont Yankee, New York Power Authority, Tennessee Valley
Authority, GPUN, the DOE, and to a number of other utility, commercial, and
government customers. Duke Power accounted for approximately 20% of Duratek's
revenue in 1993. In addition, new service contracts were won with Philadelphia
Electric and Duke Power. In response to the changing market conditions Duratek
implemented additional cost reduction efforts and expanded services to include
higher margin non-destructive examination (NDE) and professional health
physics training and consulting.

                                      6
<PAGE>
 
Environmental Services

        Environmental Services provides products and services to support the
DOE and its prime contractors in research and development, development and
implementation of minimum additive vitrification (glass making) process for
long-term waste stabilization, waste water cleanup, advanced site remediation
processes, consulting, and analysis. Environmental Services' principal
products are its proprietary DURASILR ion exchange media, its Enhanced Volume
Reduction (EVRTM) processing system, Heat Enhanced Dewatering (HEDTM) system
and Integrated Nuclear Waste Removal System which is a combination of EVR and
HED. These systems and the DURASIL ion exchange media are similar to those
products formerly used in the domestic commercial nuclear power plant 
low-level radioactive waste business sold to Chem-Nuclear Systems, Inc. 
("Chem-Nuclear") in 1990. Duratek continues to sell DURASIL products to 
Chem-Nuclear.  Duratek also has the right to sell processing systems and ion 
exchange media to government agencies such as the DOE and Department of
Defense ("DOD") and to nuclear power plants outside the U.S. In addition to
liquid waste treatment, Environmental Services is engaged in the development
of in-furnace vitrification for long-term stabilization of mixed waste.

        DOE's Five Year Plan states that environmental cleanup and 
refurbishment of inactive DOE nuclear facilities is a critical objective. Many
of the remediation tasks at these facilities involve dealing with wastes that
are both radioactive and hazardous. Restrictions on disposal of these "mixed"
wastes and limited burial space further compound the problem. The DOE and its
prime contractors are looking for innovative new approaches for separating the
radioactive and hazardous components and for long-term stabilization of these
wastes. Management believes that its experience in mixed waste streams and its
newly developed vitrification technology give Duratek an advantage in this
market.

Consulting and Staff Augmentation

        Duratek's Consulting and Staff Augmentation Group ("Consulting")
provides technicians, specialists, and professionals in a wide range of
consulting, training and staff augmentation services for a broad base of
utility, industrial, commercial, and government clients.

        According to the Nuclear News publication of "The World List    of
Nuclear Power Plants", March 1993, there are 119 nuclear power  generating units
in the United States.  Of that number, approximately 107 are operational and the
remainder are in long-term shutdown or under construction.  To control costs,
utilities maintain their permanent staffs at the level needed for steady-state
power operations.  They supplement their full-time staffs during refueling and
maintenance outages with skilled contract personnel.  These temporary personnel
typically work under the general supervision of members of the full-time staffs
of utilities.

                                        7
<PAGE>
 
        Although services for operating nuclear power plants provides a
considerable market, the fact that no new plants have been ordered in over 10
years means that the current market will expand through incorporation of
changes required by new regulations; extensive overhaul required to extend the
life of aging plants; replacement of major components such as steam
generators; startup of newly built plants and those recovering from long-term
shutdown; and decommissioning of plants that have reached the end of their
useful lives.

        Building on its solid base of nuclear power industry clients, Duratek
has expanded its services in quality assurance/control, radiation protection,
computer and communications, and environmental technologies. Duratek's
potential client base has been expanded to include other industries,
government agencies and commercial businesses. Since many of the skills needed
for support at commercial nuclear power plants are readily transferable to the
DOE cleanup market, Duratek is also expanding its consulting and staff
augmentation services in that area.

GENERAL PHYSICS CORPORATION
- ---------------------------

        The Company currently owns approximately a 28% investment in General
Physics Corporation ("General Physics"). General Physics provides a wide range
of personnel training, engineering, environmental and technical support
services to the domestic commercial nuclear power industry and to the DOE and
DOD. General Physics believes it is a leader in the field of developing
training materials, conducting training programs and providing support
services to operators, technical staff and management personnel at commercial
nuclear power plants and at nuclear weapons production and waste processing
sites in the United States.

        General Physics currently provides services to more than 400 clients,
including eight of the largest electric power companies in the United States
and four prime contractors serving the DOE. During 1993, Westinghouse Savannah
River Company ("Westinghouse"), a prime contractor at DOE facilities,
accounted for approximately 23% of General Physics' revenue. No other customer
accounted for more than 10% of General Physics' revenue during 1993. Prior to
October, 1988, when it started its DOE Services business, the Company derived
virtually all of its revenue from contracts with nuclear utilities.

        From late 1988 through mid 1992, General Physics experienced growth in
revenue primarily from services provided to the DOE at its Savannah River site
under subcontracts with Westinghouse, and to a lesser extent from services
provided to the commercial nuclear power industry. During 1992 and 1993,
General Physics experienced lower levels of contract activity at DOE
facilities which resulted in declining revenue. General Physics Nuclear
Services revenue was adversely affected in 1993 by cost reduction efforts at
many commercial nuclear utilities which are expected to continue.
Environmental Services revenue increased slightly in 1993 and General Physics
was recently awarded a one-year contract with

                                      8
<PAGE>
 
four option years to provide environmental engineering support services at 
the DOD's Aberdeen Proving Ground.  This contract has a potential value of 
approximately $17 million if all option years are exercised.

        In January 1994, General Physics acquired substantially all of the
operating businesses of Cygna Energy Services (CES), other than its non-nuclear
seismic engineering business.  CES provides design engineering, seismic
engineering, systems engineering, materials management and safety analysis
services to the commercial nuclear power industry and to the DOE.

        In January 1994, General Physics also entered into a letter of intent 
to acquire substantially all of the assets and operations of GPS. GPS provides
a wide range of training, engineering, technical support and analytical
services to various commercial industries, fossil powered electric generating
plants and the DOD. Although an agreement in principle has been reached, there
can be no assurance that a definitive agreement will be successfully
negotiated or that the transaction will close as anticipated. See "Recent
Developments - General Physics' Corporation and GPS Technologies, Inc. Proposed
Transaction".

DISTRIBUTION GROUP

FIVE STAR GROUP, INC.
- ---------------------

        The Distribution Group, incorporated under the name Five Star Group,
Inc. ("Five Star"), is engaged in the wholesale distribution of home
decorating, hardware and finishing products. Five Star has three strategically
located warehouses and office locations, with approximately 380,000 square
feet of space in New Jersey, New York and Connecticut, which enables Five Star
to service the market from Maine to Virginia.

        Five Star is the largest distributor in the U.S. of paint sundry items, 
interior and exterior stains, brushes, rollers and caulking compounds and
offers products from leading manufacturers such as Olympic, Cabot, Thompson,
Dap, 3-M, Minwax and Rustoleum. Five Star distributes its products to retail
dealers which include discount chains, lumber yards, "do-it-yourself" centers,
hardware stores and paint suppliers principally in the northeast region. It
carries an extensive inventory of the products it distributes and provides
delivery generally within 48 to 72 hours from the placement of an order.

        The primary working capital investment for Five Star is inventory.
Inventory levels will vary throughout the year reflecting the seasonal nature of
the business.  Five Star's strongest sales are typically in March through
October because of strong seasonal consumer demand for its products.  As a
result, inventory levels tend to peak in the spring and reach their lowest
levels in late fall.

        The largest customer accounted for approximately 12% of Five Star's
sales in 1993 and its 10 largest customers accounted for approximately 29% of 
such sales.  No other 

                                      9
<PAGE>
 
customer accounted for in excess of 10% of Five Star's sales in 1993.  All such 
customers are unaffiliated companies and neither Five Star nor the Company has 
a long-term contractual relationship with any of them.

        Competition within the industry is intense.  There are much larger
national companies commonly associated with national franchises such as
Servistar and True Value as well as smaller regional distributors all of whom
offer similar products and services.  Additionally, in some instances
manufacturers will bypass the distributor and choose to sell and ship their
products directly to the retail outlet.  The principal means of competition for
Five Star are its strategically placed distribution centers and its extensive
inventory of quality name brand products.  Five Star will continue to focus its
efforts on supplying its products to its customers at a competitive price and on
a timely, and consistent basis.  In the future, Five Star will attempt to
acquire complementary distributors and to expand the distribution of its line of
private-label products sold under the "Five Star" name.

INTERFERON SCIENCES, INC.
- -------------------------

        Interferon Sciences, Inc. ("ISI") is a biopharmaceutical  company
engaged in the manufacture and sale of ALFERON N Injection and the research and
development of other uses of ALFERON N Injection and other alpha 
interferon-based formulations for the treatment of certain viral diseases, 
cancers,and diseases of the immune system.

        ALFERON N Injection is the only natural-source, multi-species alpha
interferon product approved by the FDA for sale in the United States and is
approved for the intralesional treatment of refractory (resistant to other
treatment) or recurring external genital warts in patients 18 years of age or
older.

        On March 5, 1985, the United States Patent and Trademark Office
issued a patent to Hoffmann-La Roche Inc. ("Hoffmann") claiming purified human
alpha (leukocyte) interferon (regardless of how it is produced).  ISI obtained a
non-exclusivelicense from Hoffmann which allows ISI to make, use, and sellin the
United States, without a potential patent infringement claim from Hoffmann, (i)
ALFERON N Injection for the treatment of genital warts, (ii) injectable
formulations of interferon alfa-n3 (which is the same active ingredient
contained in ALFERON N Injection) for the treatment of patients who are
refractory to recombinant interferon therapy, (iii) low dose oral formulations
of alpha interferon for the treatment of human disease, and (iv) topical
formulations of interferon alfa-n3 (which is the same active ingredient
contained in ALFERON N Injection).  Hoffmann presently  owns approximately 3% of
the common stock of ISI.

        ALFERON N Injection is marketed and distributed in the United States
exclusively by Purdue Pharma L.P.("Purdue"), utilizing the sales force of The
Purdue Frederick Company, a privately-held United States pharmaceutical company.
In addition, ISI has exclusive 

                                    10
<PAGE>
 
marketing and distribution agreements with Mundipharma Pharmaceutical Company 
in Canada and with Industria Farmaceutica Andromaco in Mexico. ISI has
anoption to reacquire the United States, Canadian, and Mexican marketing and
distribution rights under certain terms and conditions. Submissions for
regulatory approval to sell ALFERON N Injection have been filed in Austria,
Canada, Israel, Mexico and the United Kingdom.

        At the present time, alpha interferon injectable products are approved
for 17 different medical uses in 63 countries. In 1993, the worldwide alpha
interferon injectable market was estimated to be over $1 billion. In an effort
to expand the market for ALFERON N Injection in the United States and obtain
additional regulatory approvals around the world, ISI is presently conducting
three multi-center randomized, open dose ranging studies with patients
infected with hepatitis C virus. In addition, based upon favorable results
from an in vitro study and a Phase 1 clinical study conducted at Walter Reed
Army Institute of Research in Bethesda, Maryland on 20 asymptomatic HIV
infected patients, ISI is planning a multi-center, randomized, controlled
clinical trial with asymptomatic HIV-infected patients. ISI is also planning
to conduct clinical trials utilizing ALFERON N Injection for the treatment of
Kaposi's sarcoma in patients with AIDS and hepatitis B.

        Additional products under development by ISI include ALFERON N Gel and
ALFERON LDO. ALFERON N Gel is a topical interferon preparation which ISI
believes has potential in the treatment of cervical dysplasia, recurrent
genital herpes, other viral diseases, and cancers. A clinical trial using
ALFERON N Gel for the treatment of patients with cervical dysplasia is
currently underway at Columbia Presbyterian Medical Center. ALFERON LDO is a
low dose oral liquid alpha interferon preparation which ISI believes has
potential for treating the symptoms of patients infected with the HIV virus
and other viral diseases. ISI conducted two clinical trials using ALFERON LDO
on patients infected with HIV virus at New York's Mount Sinai Hospital. The
National Institute of Allergy and Infectious Disease ("NIAID") is planning to
conduct a randomized, double-blind, placebo controlled clinical study with low
dose alpha interferons administered orally (including ALFERON LDO) to
determine interferon's effect on HIV related symptoms.

        On May 28, 1993, David Blech, the Chief Executive Officer, sole
shareholder and a director of D. Blech & Company, Incorporated ("DBC"), and
ISI entered into a Purchase Agreement (the "Purchase Agreement"), pursuant to
which David Blech or his designees purchased for $4.00 per unit, an aggregate
of 2,500,000 units ("Units"), each Unit consisting of two shares of common
stock, one Class A Warrant to purchase one share of common stock at an
exercise price of $3.25 per share and one Class B Warrant to purchase one
share of common stock at an exercise price of $5.00 per share. The Class A
Warrants and the Class B Warrants expire on August 31, 2000.

        Pursuant to the Purchase Agreement, a 10-year Voting Agreement (the
"Voting Agreement") among David Blech, the Company, Five Star and MXL became
effective as of May 28, 1993 pursuant to which the Company, Five Star and MXL
agreed to (a) vote all of their shares of common stock (an aggregate of
6,985,148 shares as of the date hereof), for

                                 11
<PAGE>
 
the election of the Blech Nominees as directors of ISI unless Blech or his
designees dispose of more than 1,000,000 shares of Common Stock and (b)
restrict transfer of the Common Stock held by them for one year, subject to
certain exceptions. Pursuant to the Voting Agreement, Mr. Blech and any other
purchasers under the Purchase Agreement agreed to vote for the election of two
nominees of NPDC as directors of the Company unless NPDC, MXL and Five Star
dispose of more than 2,000,000 shares of Common Stock.

       Concurrently with the execution of the Purchase Agreement, ISI entered
into a Consulting Agreement with DBC under which ISI agreed to pay $100,000
per year, payable monthly, to DBC for advisory services with respect to the
Company's field of interest and business, strategic and commercial matters
related to the biotechnology industry. The term of the Consulting Agreement
was one year and commenced on June 1, 1993.

MXL also designs and engineers state-of-the-art injection molding tools as well
as providing a commodity custom molding shop.

        As the market for optical injection molding, tooling and coating is
focused, MXL believes that the combination of its proprietary "Anti-Fog"
coating, precise processing of the "Anti-Scratch" coatings, and precise
molding and proprietary grinding and polishing methods for its injection tools
will enable it to increase its sales in the future and to expand into related
products.

                                       12
<PAGE>

("Eastern") is engaged in contract manufacturing for the electronics industry.
Eastern offers a variety of services to its customers ranging from printed
circuit board assemblies, to in-circuit testing, to functional testing, to
turnkey production and to final system production.  Eastern's customers are
among the largest United States electronics companies.

        There is significant competition within the electronics industry for 
contract manufacturing from much larger national companies as well as smaller
companies. While the electronics industry at large is experiencing a downturn
in business, Eastern feels that the lessening of off-shore competition and
"just in time" manufacturing requirements will enable it to compete more
effectively in the changing environment. The principal means of competition
for Eastern are its twenty two years of experience in printed circuit board
assembly, state-of-the-art automatic insertion, surface mount equipment and
state-of-the-art in circuit test equipment.

Item 7.  Management's Discussion and Analysis of 
         ---------------------------------------
         Financial Condition and Results of Operations
         ---------------------------------------------


RESULTS OF OPERATIONS

Overview

During 1993, the Company took steps to significantly reduce its long-term
debt. The Company, through an Exchange Offer for a large portion of its Swiss
Denominated Debt (See Note 9(a) to Notes to Consolidated Financial
Statements), as well as other repurchases from various bondholders throughout
1993, was able to reduce its long-term debt by approximately $20,583,000. As a
result of the reduction in long-term debt, the Company will be able to reduce
its annual interest expense by approximately $2,100,000. Due to the inclusion
of a portion of the Company's shares of common stock of Interferon Sciences,
Inc. (ISI) as part of the consideration in the Exchange Offer in the third
quarter of 1993, the Company currently owns less than 50% of ISI (36%), and
therefore now accounts for the results of ISI on the equity basis. In 1993,
the Company realized an extraordinary gain, net of taxes, on the early
extinguishment of debt of $1,819,000. In 1993, the Company also incurred
reduced interest expense at the corporate level on the Company's long-term
Swiss Debt obligations due to the Company's continuing practice of
repurchasing and reducing its Swiss Debt. In addition, the Company incurred
reduced interest relating to short-term borrowings due to reduced borrowings
at lower rates of interest. In 1993, the loss before income taxes and
extraordinary item was $8,371,000, as compared to a loss of $13,178,000 in
1992 and income of $1,157,000 in 1991. The decrease in the loss in 1993 is due
to several factors. As a result of the Exchange Offer discussed above, the
Company realized a $3,795,000 gain from the transfer of a portion of the
Company's holdings of shares of ISI and GTS Duratek, Inc.'s (Duratek) common
stock. In addition, the Company realized a gain of $1,353,000 on the issuance
of common stock and common stock warrants by Duratek, relating to its
acquisition of an option to acquire certain technologies relating to the
vitrification of certain medical and hazardous wastes. The Health Care and the
Electronics Groups experienced reduced operating losses in 1993. The Health
Care Group which is comprised of the results of ISI experienced reduced
operating losses in 1993 as a result of ISI being accounted for on the equity
basis commencing in the third quarter of 1993. The Electronics Group, which is
Eastern Electronics Manufacturing Corporation (Eastern), the Company's
electronic assembly and manufacturing subsidiary, incurred reduced operating
losses as a result of their successful efforts to reduce overhead and costs of
sales. The above improvements in 1993 were partially offset by reduced
operating profits at the Distribution and Physical Science Groups, in addition
to a foreign currency transaction gain of $901,000 realized in 1993 as
compared to a net foreign currency transaction gain of $3,362,000 realized in
1992, relating to the Company's decision not to hedge its Swiss denominated
debt. The Distribution Group, which is the Five Star Group, Inc. (Five Star),
the Company's distributor of home decorating, hardware and finishing products
had reduced operating profits as a result of reduced gross margin percentages
and increased operating

                                     19
<PAGE>
 
costs. The Physical Science Group, which is comprised of GPS Technologies Inc.
(GPS), a 92% owned subsidiary, and GTS Duratek, Inc. (Duratek), a 66% owned
subsidiary, had reduced operating profits as a result of losses incurred by
Duratek due to reduced revenues and gross margin percentages achieved. The
Optical Plastics Group, which is MXL Industries, Inc. (MXL), the Company's
injection molding and coating subsidiary, had a marginal decrease in operating
profits.

During 1992, the loss before income taxes and extraordinary items was
$13,178,000 compared to income of $1,157,000 in 1991. The change from a profit
in 1991 to a loss in 1992 was primarily the result of the public offering by
General Physics Corporation (GP) in October 1991, through which the Company
sold 68% of its GP common stock and recognized a gain on the transaction of
$18,844,000. The Company currently owns approximately 28% of GP. The effect of
the gain on GP was partially offset by improved operating results achieved in
1992 by the remaining companies within the Physical Science Group, GPS and
Duratek. At the corporate level, improved operating results in 1992 were
partially the result of gains recognized on the sale of certain investments
and the continuing reduction in interest expense as a result of reduced 
short-term borrowings, lower rates of interest on the Company's variable rate
obligations and reduced interest on the Company's Swiss Debt obligation due to
the Company's continuing practice of repurchasing its Swiss Debt from time to
time. The improved operating results within the Physical Science Group were
due to both GPS and Duratek achieving operating profits in 1992 as opposed to
operating losses in 1991. GPS achieved a significant turnaround as a result of
reduced losses at its subsidiary, GP International Engineering & Simulation,
Inc. (GPI), an operating profit generated for the first time by its subsidiary
GP Environmental Services, Inc. (GPE) and an overall improvement within the
core businesses of GPS. Duratek showed an improvement in operations during
1992 as a result of increased sales and gross profit in both its Environmental
Services and Consulting and Staff Augmentation businesses, as well as the
impact of the effort in the latter half of 1991 to consolidate and streamline
its administrative structure. The improvements in operations achieved by the
current members of the Physical Science Group and at the corporate level were
partially offset by an increased operating loss at the Electronics Group and
reduced operating profits at the Optical Plastics Group. The Electronics
Group, incurred increased operating losses due to reduced sales and inceased
operating costs and the effect of reserves taken for obsolete inventory. The
Optical Plastics Group had a small decrease in operating profit as a result of
weakness in the precision tooling part of its business,as well as reduced
orders from a number of MXL's establishedcustomers in the beginning of 1992.
The Health Care Group's operating loss and the Distribution Group's operating
profit remained virtually unchanged in 1992.

Sales

Consolidated sales from continuing operations decreased by $6,082,000 in 1993
to $189,683,000 as a result of reduced sales in the Physical Science, Health
Care and Electronics Groups, partially offset by increased sales achieved by
the Distribution Group. Sales decreased by $63,168,000 in 1992, to
$195,765,000, as a result of the transfer in April 1991 of a majority interest
in American White Cross, Inc. (AWC), formerly NPM

                                     20
<PAGE>
 
Healthcare,Inc., in which the Company currently has a 14% interest, and the
public offering by GP in October 1991, which resulted in GP and AWC no longer
being consolidated entities. The decrease in 1992 was partially offset by
increased sales within the Distribution Group and by the remaining companies
in the Physical Science Group.

The Physical Science Group sales decreased from $162,727,000 in 1991 to
$109,303,000 in 1992 and to $102,977,000 in 1993. The reduced sales of
$6,326,000 in 1993 were primarily attributable to reduced sales achieved by
Duratek as a result of reduced revenues generated by its consulting and staff
augmentation business, as a result of a reduced demand for services provided
to nuclear utilities. In addition, Duratek's sales decreased as a result of
reduced revenues achieved by the environmental services business due to delays
in the award of certain technology contracts by the Department of Energy.
During 1992, sales decreased by $53,424,000, due to the public offering by GP
on October 3, 1991, from which time the results of GP were accounted for on
the equity basis, since the Company's percentage of ownership was reduced to
approximately 28%. In 1991, the Physical Science Group included sales of
$62,325,000 for GP. The loss of GP's sales in 1992 was partially offset by
increased sales at both GPS and Duratek. Duratek generated increased sales in
1992 as a result of work performed on two new environmental technology
projects, as well as an increase in services provided by the consulting and
staff augmentation business. GPS generated increased revenues in new business
areas such as environmental analytical services and full scope simulation.
These increases at GPS were partially offset by a reduction in revenue for
certain subcontracts, which terminated in 1991, for construction management
services provided to the Department of the Army.

The Distribution Group sales increased from $64,788,000 in 1991 to $68,450,000
in 1992 and to $74,109,000 in 1993. The increase of $5,659,000, or 8% in 1993
was due to reduced competition in one of Five Star's geographic regions, as
well as continued growth in the hardware business, which was introduced in
1992. The increase of $3,662,000, or 6%, in 1992 was attributable to the
introduction during the year of a new line of hardware supplies.

The Health Care Group sales decreased from $14,607,000 in 1991 to $4,042,000
in 1992 and to zero in 1993. The reduction in sales in 1993 was due to ISI not
having any sales of its product, ALFERONR N Injection, in 1993. In January
1994, ISI received an order for 45,000 vials of ALFERONR N Injection from the
Purdue Frederick Company (Purdue). As a result of the Exchange Offer, through
which the Company's interest in ISI fell below 50%, ISI is currently being
accounted for on the equity basis. The $10,565,000 reduction in sales in 1992
was due to the transfer on April 8, 1991 of a majority interest in AWC,
partially offset by increased sales by ISI of ALFERONR N Injection to its
marketing partner, Purdue. In December 1991, Purdue agreed to purchase an
aggregate of 45,000 vials of ALFERONR N Injection from the Company over
approximately a six month period which commenced in March 1992 and was
completed in September 1992.

The Optical Plastics Group sales decreased from $9,454,000 in 1991 to
$7,862,000 in 1992 and to $7,817,000 in 1993. The decreased sales in 1992 was
due to weakness at MXL's

                                     21
<PAGE>
 
precision tooling division, as well as reduced orders from a number of MXL's
established customers in the beginning of 1992.

The Electronics Group sales decreased from $7,151,000 in 1991 to $5,968,000 in
1992 and to $3,836,000 in 1993. The decreased sales in 1992 and the continued
weakness in 1993 was the result of the weakness in the electronics industry
and Eastern's plan to concentrate its efforts on sales to customers who
provide more profitable margins.

Gross margin

Consolidated gross margin was $36,013,000 or 14% of net sales in 1991,
$29,772,000 or 15% of net sales in 1992 and $27,519,000 or 15% in 1993. In
1993, the decrease in gross margin of $2,253,000 occurred within the Health
Care, Distribution and Physical Science Groups. In 1992, the decrease in gross
margin of $6,241,000 occurred primarily in the Physical Science Group as a
result of the public offering by GP in October 1991, and to a lesser extent,
in the Health Care Group due to the transfer in April 1991 of a majority
interest in AWC in which the Company currently has a 14% interest. The reduced
gross margin in 1992 was partially offset by increased gross margin achieved
by the Distribution Group as a result of increased sales.

The Physical Science Group gross margin decreased from $18,370,000, or 11% of
net sales in 1991 to $13,728,000 or 13% of net sales in 1992 and to
$12,941,000, or 13% of net sales in 1993. In 1993, the reduced gross margin
was primarily attributable to reduced gross margins achieved by Duratek as a
result of reduced sales as well as a decrease in the gross margin percentage
achieved within Duratek's consulting and staff augmentation business because
of increasing competitive pressures within the industry. The reduced gross
margin achieved by Duratek was partially offset by GPS, which generated
increased gross margins as a result of an improved mix of services during
1993. In 1992, the decreased gross margin was due to the public offering by GP
in October 1991, partially offset by increased gross margins at Duratek and
GPS. The increased gross margin dollars and percentage at GPS was due to
increased sales, significant profit improvements at GPI and GPE during 1992,
as well as an improved mix of services performed at higher margins within the
core businesses. Duratek achieved increased gross margins in 1992 as a result
of increased revenues generated by its environmental technology projects.

The Distribution Group gross margin increased from $11,679,000 or 18% in 1991
to $12,355,000 or 18% of sales in 1992 and decreased to $11,718,000 or 16% in
1993. In 1993, the reduced gross margin was the result of the reduced gross
margin percentage achieved in 1993. The reduced gross margin percentage in
1993 was the result of a change in the product mix as well as competitive
price pressures within the industry. In 1994, the Group has started taking
steps to reduce its costs of sales in order to improve its operating margins
in the future. In 1992, the increased gross margin was the result of increased
sales due to the introduction of a new line of hardware products.

   The Health Care Group gross margin decreased from $2,509,000 or 17% of net
sales in 

                                     22
<PAGE>
 
1991 to $358,000 or 9% of net sales in 1992 and to $(699,000) in 1993. The
negative gross margin in 1993 was the result of facility costs incurred by
ISI, notwithstanding the suspension of production, and lack of sales of
ALFERONR N Injection during 1993. The decrease in gross margin in 1992 was the
result of the transfer on April 8, 1991 of a majority interest in AWC, as
discussed above. The reduced gross margin percentage in 1992 is attributable
to the low gross margin percentages achieved by ISI due to the write-down of
inventory to its estimated net realizable value, as a result of increased unit
production costs caused by limited production volumes.

The Optical Plastics Group gross margin decreased from $3,231,000 or 34% of
net sales in 1991 to $2,740,000 or 35% of net sales in 1992 and to $2,642,000
or 34% of net sales in 1993. The small decrease in gross margin in 1993 was
the result of marginally reduced sales and gross margin percentage. In 1992,
the reduced gross margin was the result of reduced sales volume.

The Electronics Group gross margin increased from $221,000 or 3% of net sales
in 1991 to $561,000 or 9% of net sales in 1992 and decreased to $546,000 or
14% of net sales in 1993. The small decrease in gross margin in 1993 and
increased gross margin in 1992, in spite of reduced sales at Eastern in both
years, was attributable to the continuing improvement in gross margin
percentages as a result of a better product mix, a reduction in the fixed
manufacturing costs and improved operating efficiencies.

Investment and other income, net
Investment and other income was $2,790,000 in 1991, $6,221,000 in 1992 and
$3,358,000 in 1993, respectively. In 1993 the decrease in investment and other
income, net was primarily attributable to a net foreign currency transaction
gain of $901,000 in 1993 as compared to a gain of $3,362,000 in 1992. In
addition, in 1993 the Company realized reduced revenues relating to interest
income, and in the equity in earnings of 20% to 50% owned subsidiaries as
compared to 1992. These decreases were partially offset by reserves taken and
losses realized by the Company on certain assets and investments in 1992. In
1992, the increase in investment and other income, net was primarily due to
two factors. In 1992, the Company realized increased gains on the sales of
certain investments, and recognized an expense for reserves taken and losses
realized on certain assets of $1,336,000 in 1992 as compared to $4,774,000 in
1991. In 1992, the Company realized a net foreign currency transaction gain of
$3,362,000, as compared to a gain of $3,042,000 in 1991. The reserves were
taken in 1992 and 1991 due primarily to reduced values and impairments
relating to long-term investments and related assets accounted for on the cost
basis. The Company evaluates its long-term investments at least annually. An
investment is written down or written off if it is judged to have sustained a
decline in value which is other than temporary. During 1991, a 19% interest in
and advances to a vendor and distributor of pay telephones was written down by
$3,100,000, to an estimated residual value of $175,000, since the telephone
company ceased marketing its principal product in 1991. This resulted from (a)
the loss by the telephone company of two major vending accounts in 1991, which
substantially reduced revenues and (b) the telephone company's effort to sell
telephones as well as to vend them

                                     23
<PAGE>
 
was unsuccessful in 1991. Based upon the fact that the remaining vending
revenues were insufficient to support operations the telephone company ceased
operations. In 1992, the estimated residual value of $175,000 of this
investment, which was based upon estimated proceeds on liquidation of
telephone equipment, was written off since it was determined that such sales
could not be consummated. Additionally, in 1992, the Company fully reserved
its investment of $305,000 in a medical blood center company. The blood center
company ceased operations in 1992 as its major investor, a large financial
institution decided to no longer provide financing and working capital. In
1991 and prior years, the medical blood center company received substantial
funding for its centers and the financial institution provided working capital
and equity financing. In both 1991 and 1992, a number of other relatively
small investments were written off or written down because the Company's
periodic evaluations indicated declines in value which were judged to be other
than temporary.

At December 31, 1993, there was an aggregate of SFr. 25,398,000 of Swiss
denominated indebtedness outstanding, of which SFr. 23,680,000 represents
principal amount outstanding and SFr. 1,718,000 represents interest accrued
thereon. Foreign currency valuation fluctuations may adversely affect the
results of operations and financial condition of the Company. In order to
protect itself against currency valuation fluctuations, the Company has at
times swapped or hedged a portion of its obligations denominated in Swiss
Francs. At December 31, 1993, the Company had not hedged its Swiss Franc
obligations. If the value of the Swiss Franc to the U.S. Dollar increases, the
Company will recognize transaction losses on the portion of its Swiss Franc
obligations which are not hedged. On December 31, 1993, the value of the Swiss
Franc to the U.S. Dollar was 1.485 to 1. There can be no assurance that the
Company will be able to swap or hedge obligations denominated in foreign
currencies at prices acceptable to the Company or at all. The Company will
continue to review this policy on a continuing basis.

Selling, general, and administrative expenses
Selling, general and administrative expenses (SG&A) decreased from $38,356,000
in 1991 to $36,274,000 in 1992 and to $35,600,000 in 1993. In 1993, the
decrease in SG&A was primarily attributable to ISI being accounted for on the
equity basis during the third quarter of 1993, as a result of the Exchange
Offer discussed above, in which the Company's interest in ISI fell below 50%.
In addition, the Electronics Group also experienced reduced SG&A expenses as a
result of reduced personnel requirements due to reduced sales in 1993 and
Eastern's continuing effort to streamline its organization. The reduced SG&A
within the Health Care and Electronics Groups in 1993 were partially offset by
increased SG&A incurred by the Distribution and Physical Science Groups. The
increased SG&A at The Physical Science Group was due to increased operating
costs and the increased SG&A at the Distribution Group was the result of the
large increase in sales which led to increased selling expenses, as well as
additional costs incurred by Five Star to support the growth in sales. The
Optical Plastics Group had a marginal increase in SG&A in 1993. In 1992, the
decrease in SG&A expenses was primarily due to decreases in the Health Care
Group and the Physical Science Group as a result of the transfer on April 8,
1991 of a majority interest in AWC and

                                     24
<PAGE>
 
the public offering by GP in October 1991, respectively. The decrease was
partially offset by increased SG&A within the Distribution Group as a result
of Five Star's expansion into the hardware supply distribution business and
increased SG&A within the Electronics Group due to costs connected with
Eastern's efforts to restructure its business operations.

Research and development costs
The Company's research and development activities are conducted both
internally and under various types of arrangements at outside facilities.
Research and development costs, which are primarily attributable to ISI, were
$4,651,000, $4,645,000 and $2,847,000 for 1991, 1992, 1993, respectively. In
1993, the reduced research and development costs were the result of the
Company's ownership in ISI falling below 50% in the third quarter of 1993, due
to the Exchange Offer discussed above, and therefore, the Company began
accounting for ISI on the equity method from that time. In 1992, ISI
experienced increased research and development costs because of increased
levels of research on ALFERONR N Gel, ALFERONR LDO and other proprietary
research. The increased spending at ISI in 1992 was offset by reduced spending
on various corporate projects.

Interest expense
Interest expense aggregated $15,579,000 in 1991, $11,044,000 in 1992 and
$8,325,000 in 1993. The reduced interest expense in 1992 and the further
reduction in 1993, was the result of the Company's continuing successful
effort to reduce its interest expense at the corporate level due to reduced
short-term borrowings, lower rates of interest on the Company's variable rate
obligations and reduced interest on the Company's Swiss Debt obligations due
to the Exchange Offer in 1993 and the Company's practice of repurchasing Swiss
Debt from time to time.

Income taxes and extraordinary item
Income tax benefit (expense) from operations for 1991, 1992 and 1993 was
$(549,000), $(427,000) and $575,000, respectively.

In 1993, the Company recorded an income tax benefit of $1,043,000, of which
$973,000 relates to Federal income taxes, in continuing operations as a result
of the income tax expense allocated to the extraordinary gain recognized on
the early extinguishment of debt under the provisions of FASB No. 109.

In 1992, the Company's loss before income taxes from operations exceeded its
gains from extraordinary items: therefore, pursuant to accounting policies of
the Company, then in effect under APB No. 11, "Accounting for Income Taxes",
no income tax expense applicable to such extraordinary gains was recognized.
The income tax expense for 1992 of $427,000 represents state and  local income
taxes.

In 1991, despite the Company's $1,157,000 income before income taxes from
operations, no Federal income tax expense was recognized. This is due
principally to significant permanent differences between financial and tax
reporting of 1991 transactions, including the

                                     25
<PAGE>
 
elimination for tax purposes of the $18,844,000 gain on the sale of GP stock,
net of a gain recognized only for tax purposes upon ISI ceasing to be a member
of the Company's consolidated Federal income tax return group on May 31, 1991.
The income tax expense for 1991 of $549,000 represents state and local income
taxes.

As of December 31, 1993, the Company has approximately $34,770,000 of
consolidated net operating losses available for financial statement reporting
purposes.

Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes," was adopted by the Company in 1993 on a prospective basis. (See Note
15 to the Consolidated Financial Statements). This standard requires that
deferred income taxes be recorded following the liability method of accounting
and adjusted periodically when income tax rates change. As of December 31,
1993, the Company was not carrying any deferred tax accounts. Adoption of the
new Statement did not have a material effect on the Company's financial
condition or results of operations.

Liquidity and capital resources
At December 31, 1993, the Company had cash, cash equivalents and marketable
securities totaling $10,976,000. GPS and Duratek had cash, cash equivalents
and marketable securities of $547,000 at December 31, 1993. The minority
interests of these companies are owned by the general public, and therefore,
the assets of these subsidiaries have been dedicated to the operations of
these companies and may not be readily available for the general corporate
purpose of the parent.

The Company believes that it has sufficient cash, cash equivalents and
marketable securities and borrowing availability under existing and potential
lines of credit to satisfy its cash requirements until the first scheduled
maturity of its Swiss Franc denominated indebtedness on March 1, 1995.
However, in order for the Company to meet its long-term cash needs, which
include the repayment of $12,757,000 of Swiss Franc denominated indebtedness
scheduled to mature in 1995 and $7,115,000 of Swiss Franc denominated
indebtedness which is scheduled to mature in 1996, the Company must obtain
additional funds from among various sources. The Company has historically
reduced its long-term debt through the issuance of equity securities in
exchange for long- term debt. In addition to its ability to issue equity
securities, the Company believes that it has sufficient marketable long-term
investments, as well as the ability to obtain additional funds from its
operating subsidiaries and the potential to enter into new credit
arrangements. The Company reasonably believes that it will be able to
accomplish some or all of the above transactions in order to fund the
scheduled repayment of the Company's long-term Swiss debt in 1995.

For the year ended December 31, 1993, the Company's working capital decreased
by $11,653,000 to $33,224,000, reflecting the effect of the Company's interest
in ISI falling below 50%, and being accounted for on the equity basis.
Consolidated cash and cash equivalents decreased by $6,945,000 to $10,976,000
at December 31, 1993.

                                     26
<PAGE>
 
The decrease in cash and cash equivalents of $6,945,000 in 1993 primarily
resulted from the effect of the Company's interest in ISI falling below 50%,
and being accounted for on the equity basis as well as cash used, in
operations of $2,507,000, investing activities of $2,593,000 and financing
activities of $1,845,000. Cash used in operations was primarily required to
fund the operating loss for the year. The cash used in investing activities
was for increases in certain investments and for investment in property, plant
and equipment and intangible assets. Financing activities consisted primarily
of repayments and reductions in short-term borrowings and repayments of long-
term debt, offset by proceeds from short-term borrowings and long-term debt.
At December 31, 1993, the Company at the parent company level had
substantially exhausted its ability to borrow funds from its subsidiaries
under their respective line of credit arrangements.

The Company's principal manufacturing facilities were constructed subsequent
to 1976 and management does not anticipate having to replace major facilities
in the near term. As of December 31, 1993, the Company has not contractually
committed itself for any other new major capital expenditures.

                     INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
National Patent Development Corporation:


We have audited the consolidated financial statements of National Patent
Development Corporation and subsidiaries as listed in the accompanying index.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of National
Patent Development Corporation and subsidiaries at December 31, 1993 and 1992,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1993, in conformity with generally
accepted accounting principles.

As discussed in Note 15 the Company has adopted SFAS No. 109, "Accounting for
Income Taxes", as of January 1, 1993.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Summary of significant accounting policies

Principles of consolidation and investments. The consolidated financial
statements include the operations of National Patent Development Corporation and
its majority-owned subsidiaries (the Company). Investments in 20% - 50% owned
companies are accounted for on the equity basis, and marketable equity
securities of less than 20% owned companies are accounted for at the lower of
aggregate cost or market. Other investments in less than 20% owned companies are
accounted for on the cost basis. All significant intercompany balances and
transactions have been eliminated in consolidation.

Statements of cash flows. For purposes of the statement of cash flows, the
Company considers all highly liquid instruments with maturities of three months
or less from purchase date to be cash equivalents.

Marketable securities. Marketable securities at December 31, 1992 consisted of
United States Government obligations, carried on the balance sheet at cost by
the Company. The market value of marketable securities at December 31, 1992 was
$4,606,000.

Inventories. Inventories are valued at the lower of cost or market, principally
using the first-in, first-out (FIFO) method.

Foreign currency transactions. The Company's Swiss Bonds (see Note 9) are
subject to currency fluctuations and the Company has hedged portions of such
debt from time to time. During the years ended December 31, 1993, 1992, and
1991, the Company realized foreign currency transaction gains of $901,000,
$3,362,000 and $3,042,000, respectively. These amounts are included in
investment and other income, net. At December 31, 1993, the Company had not
hedged its Swiss Franc obligations.

Contract revenue and cost recognition. The Company provides services under time-
and-materials, cost-plus-fixed-fee, and fixed-price contracts. Revenue from
contracts is recognized on the percentage-of-completion method as costs are
incurred and includes estimated fees at predetermined rates. Differences between
recorded costs, estimated fees, and final billings are recognized in the period
in which they become determinable. Costs and estimated earnings in excess of
billings on uncompleted contracts are recorded as an asset. Billings in excess
of costs and estimated earnings on uncompleted contracts are recorded as a
liability. Generally, contracts provide for the billing of costs incurred and
estimated fees on a monthly basis and do not provide for retainage. Retainages,
amounts subject to future negotiation, amounts expected to be collected after
one year, and amounts related to claims are not material.

1. Summary of significant accounting policies (Continued)

Property, plant, and equipment. Property, plant, and equipment are carried at
cost. Major additions and improvements are capitalized while maintenance and
repairs which do not extend the lives of the assets are expensed currently. Gain
or loss on the disposition of property, plant, and equipment is recognized in
operations when realized.

Depreciation. The Company provides for depreciation of property, plant and
equipment primarily on a straight-line basis over the following estimated useful
lives:

</TABLE>

Intangible assets. The excess of cost over the fair value of net assets of
businesses acquired is recorded as goodwill and is amortized on a straight-line
basis generally over periods ranging from 5 to 40 years. The Company capitalizes
costs incurred to obtain and maintain patents and licenses. Patent costs are
amortized over the lesser of 17 years or the remaining lives of the patents, and
license costs over the lives of the licenses. The Company also capitalizes costs
incurred to obtain long-term debt financing. Such costs are amortized on an
effective yield basis over the terms of the related debt and such amortization
is classified as interest expense in the Consolidated Statements of Operations.

The periods of amortization of goodwill are evaluated at least annually to
determine whether events and circumstances warrant revised estimates of useful
lives. This evaluation considers, among other factors, expected cash flows and
profits of the businesses to which the goodwill relates. Goodwill is written off
when it becomes evident that it has become permanently impaired.

Treasury stock. Treasury stock is recorded at cost. Reissuances of treasury
stock are valued at market value at the date of reissuance. The cost of the
treasury stock is relieved from the treasury stock account and the difference
between the cost and market value is recorded as additional paid in capital.

1. Summary of significant accounting policies (Continued)

Sales of stock by a subsidiary. The Company records in the Consolidated
Statement of Operations any gain or loss realized when a subsidiary sells its
shares at an offering price which differs from the Company's carrying amount per
share of such subsidiary's stock.

Income taxes. The Company files a consolidated Federal income tax return that
includes each domestic subsidiary in which the Company has at least 80% voting
control. The Company adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes", effective Janaury 1, 1993. Adoption of the
new Statement did not have a significant effect on the Company's financial
condition or results of operations.

Income (loss) per share. Per share data is based on the weighted average number
of shares outstanding, including Class B capital stock, and dilutive common
stock equivalents. Presentation of fully diluted earnings per share is not
required because the effect is less than 3% or is antidilutive. The weighted
average number of shares outstanding for the years ended December 31, 1993, 1992
and 1991 were 17,125,900, 15,771,301 and 15,393,781, respectively.

2. GPS Technologies, Inc.

On October 3, 1991, General Physics Corporation (GP)completed a public of 4
million shares of common stock at a price of $13 per share. The Company offered
3,846,540 shares of stock, and the remainder was offered by certain non-
affiliated shareholders. The Company received net proceeds after expenses of
$43,997,000, and from the proceeds was required to make several repayments of
long-term debt and short-term borrowings. The Company repaid $16,735,000 of
short-term borrowings, $5,163,000 of long-term debt and $2,039,000 of accrued
interest payable on its Swiss Convertible Bonds. Included in expenses were
legal, printing and accounting costs, bonuses paid to key employees of the
Company, as well as other costs. The Company recognized a gain of $18,844,000
from this transaction.

2. GPS Technologies, Inc. (Continued)

In connection with the public offering, a reorganization was effected on
September 25, 1991 whereby GP transferred certain operations and related assets
and liabilities to a new subsidiary, GPS Technologies, Inc. (GPS), formerly
named General Physics Services Corp. GP retained the business, assets and
liabilities of its Nuclear Services, Department of Energy Services and
Environmental Services Groups. Included among the businesses and assets
transferred to GPS were certain leases of property and equipment, and two
finance subsidiaries that own power plant control room simulators. As a result
of the public offering and the reorganization, the Company owns approximately
28% of GP and 92% of GPS. The financial position and results of operations of GP
are included in the consolidated accounts of the Company for all periods
presented through September 30, 1991. On October 3, 1991, the Company's
ownership fell below 50%. Thereafter, the Company's investment in GP has been
accounted for on the equity basis and the Company's share of GP's income (loss)
for the three months ended December 31, 1991 and years ended December 31, 1992
and 1993 in the amount of $432,000, $(144,000) and $316,000, respectively, after
the amortization of the underlying goodwill, is included in the caption
"Investment and other income, net" appearing in the consolidated statements of
operations. The financial position and results of operations of GPS are included
in the consolidated accounts of the Company. At December 31, 1993, the Company's
investment in GP was approximately $11,753,000, of which $6,829,000 represents
the difference between the carrying amount of the investment and the amount of
the underlying equity in the net assets. Such amount is included in investments
and advances on the Company's consolidated balance sheet and is being amortized
on a straight-line basis over its estimated benefit period, 30 years. At
December 31, 1993, the Company owned 1,771,407 shares of GP with a total market
value of $6,864,000.

Condensed financial information for GP is as follows as of December 31, 1993 and
1992 and for the years then ended (in thousands):

3. GTS Duratek, Inc.

On November 2, 1990, GTS Duratek, Inc. (Duratek), a majority owned subsidiary,
purchased General Technical Services, Inc. (GTS) from GP for a purchase price of
$7,500,000 in cash, 3,500,000 shares of Duratek's common stock and a $1,250,000
note. GTS, based in Columbia, Maryland, is a supplier of consulting and staff
augmentation services to utilities, Government agencies, and commercial
businesses. On December 31, 1992, Duratek issued 450,000 shares of Duratek
common stock to GPS in exchange for the $1,250,000 note and $150,000 of accrued
interest. In 1993, the Company distributed 667,134 shares of Duratek stock as
part of an Exchange Offer (See Note 9(a)). After the acquisition of GTS, the
retirement of the note and accrued interest and the Exchange Offer,
approximately 46% of the outstanding shares of Duratek's common stock is owned
by GPS (after the reorganization discussed in Note 2) and 20% of the shares are
owned by the Company. The Company, as a result of owning 92% of GPS, now
controls approximately 66% of Duratek. Duratek also provides environmental
services which includes the cleanup of water and other liquids containing
radioactive and/or hazardous (mixed waste) contaminants and in-furnace
vitrification for long-term stabilization of such waste.

In the fourth quarter of 1993, Duratek entered into a series of agreements which
resulted in the formation of a 50% owned company,Vitritek Environmental, Inc.
(Vitritek). The purpose of Vitritek is to develop technologies relating to the
vitrification of medical, hazardous and asbestos waste. In consideration for its
50% interest in Vitritek, Duratek contributed its option to acquire all rights,
title and interest in certain medical and hazardous waste vitrification
technologies. Duratek acquired this option for warrants to purchase 500,000
shares of Duratek's common stock for $4.00 per share and cash of $500,000
provided by the owners of the other 50% interest in Vitritek. The warrants
expire on September 30, 1997. In connection with these transactions, Duratek
agreed to sell to the two principal shareholders of the corporation which
contributed certain technologies relating to asbestos waste vitrification, and
who hold the other 50% interest in Vitritek, a total of 562,500 shares of
Duratek's common stock at $4.00 per share. Duratek received in consideration for
the shares, $1,500,000 in cash, and the two shareholders' interests in other
assets valued at $750,000.

4. Interferon Sciences, Inc.

Interferon Sciences, Inc. (ISI) is a 36% owned affiliate of the Company. It is
engaged in the manufacture and sale of ALFERONR N Injection, ISI's first product
commercially approved by the FDA for the treatment of recurring and refractory
external genital warts, and the research and development of other alpha
interferon based products for the treatment of viral diseases, cancers and
diseases of the immune system.

On July 12, 1993, the Company commenced an Exchange Offer for its Swiss Franc
denominated Bonds and its Dual Currency Bonds. (See Note 9(a)). As a result of
the inclusion of a portion of the Company's shares of Common Stock of ISI as
part of the consideration in the Exchange Offer, the Company's ownership in ISI
fell below 50%, and therefore, commencing during the third quarter of 1993, the
Company accounted for the results of ISI on the equity basis. The Company's
investment in ISI of approximately $6,167,000 is included in "Investments and
Advances" on the Consolidated Balance Sheet. At December 31, 1993, the Company
owned 6,985,000 shares of ISI, with a market value of $32,743,000. The Company's
share of ISI's loss included in Investment and other income, net is $857,000 in
1993.

On October 29, 1991, ISI completed a public offering of 2,300,000 shares of its
common stock at $5.00 per share resulting in net proceeds to ISI of
approximately $9,588,000. In connection with the public offering, the Company
converted its outstanding advance to ISI at September 30, 1991 of $4,985,000
into $2,200,000 of common stock and contributed the remainder to capital in
excess of par value.

On May 30, 1991, the Company exchanged its ISI Class B common stock for an equal
number of shares of common stock. As a result, on that date, ISI ceased to be
included in the Company's consolidated Federal income tax return.

On April 12, 1991, ISI, the Company, The Purdue Frederick Company (Purdue
Frederick) and certain other companies (The Purdue Affiliates) entered into an
agreement (the Funding Agreement). Under the terms of the Funding Agreement, (i)
The Purdue Affiliates agreed to purchase $3,600,000 of ISI common stock at a
price of $4.10 per share (which occurred on June 14, 1991), (ii) on June 3,
1991, the Company exchanged $3,800,000 of the Company's common stock (with a
guaranteed value of $3,800,000 of proceeds for ISI from the sale of the
Company's common stock) for an equal value of ISI common stock and, (iii) Purdue
Frederick agreed to convert $1,975,000 of the prepayments for product made by
it, $850,000 in 1990, $425,000 in January 1991, and $700,000 in February 1991
into shares of ISI common stock at $4.10 per share (which occurred on June 14,
1991). Between August and October, 1991, ISI received $1,200,000 in net proceeds
from the sale of the Company's common stock and the Company paid ISI the
remaining $2,600,000 on October 31, 1991 (which represents the difference
between the guaranteed amount of $3,800,000 and the amount realized from the
sale of the ISI common stock which was $1,200,000).

(a) On April 8 and October 3, 1991, the Company entered into two amendments to
its November 1, 1989, $15,000,000 Revolving Credit and Term Loan Agreement (the
Loan Agreement). Under the terms of the amendments, the outstanding balance of
$10,346,000 at October 3, 1991, was payable in nine equal quarterly installments
of $1,150,000 which commenced on March 31, 1992. The loan bore interest at a
rate equal to 1/2% in excess of the bank's prime rate. On September 9, 1992, the
Company amended the Loan Agreement. Under the terms of the amendment, the
outstanding balance at January 1, 1992 is payable in four quarterly installments
of $1,150,000, $2,308,000, $1,156,000 and $5,732,000, commencing September 30,
1992. In October 1992, the bank released the $5,000,000 in cash collateral,
which was used to reduce the loan balance and the last scheduled payment by
$5,000,000. The bank agreed to defer the December 31, 1992 payment of $2,308,000
to April 1993. The entire loan balance of $4,196,000 at December 31, 1992 was
classified as a current liability. In April 1993, the Company repaid the balance
of the loan. (See Note 7(b)).

(b) In April 1990, the Five Star Group, Inc., (Five Star) entered into a three
year line of credit arrangement with a bank. Five Star could borrow up to a
maximum of $17,000,000, subject to the level of its qualified accounts
receivable and inventory, at an interest rate of 3/4% in excess of the prime
rate, subject to reduction, based upon certain financial criteria. The line of
credit was secured by substantially all the intangible and tangible property of
Five Star. As part of the agreement, the Company could borrow up to a maximum of
$7,000,000 from Five Star. As of December 31, 1992, $13,506,000 was borrowed by
Five Star.

In April 1993, Five Star and MXL Industries, Inc. ("MXL") entered into a
revolving credit and term loan agreement (the "Five Star Loan Agreement" and
"MXL Loan Agreement"). The Five Star Loan Agreement, which replaced the above
agreement, provided for a $20,000,000 revolving credit facility (the "Five Star
Revolving Credit Facility") and a $5,000,000 term loan (the "Five Star Term
Loan"). The Five Star Revolving Credit Facility is a three year committed
facility which allows Five Star to borrow amounts equal to 40% of Eligible
Inventory (as defined) and 75% of Eligible Receivables (as defined) at an
interest rate of 1% in excess of the prime rate. At December 31, 1993, the
interest rate was 7%. As of December 31 1993, $11,732,000 was borrowed under the
Five Star Revolving Credit Facility and Five Star had no additional
availability.

$417,000 which commenced October 31, 1993, and a final payment of approximately
$830,000 on April 30, 1996. The Five Star Term Loan bears interest at 1 % in
excess of the prime rate, and was 7 3/8 % at December 31, 1993. The Five Star
Revolving Credit Agreement and the Five Star Term Loan are secured by all of the
assets of Five Star and 1,359,375 shares of common stock of ISI and 1,062,500
shares of common stock of GP, which were contributed to Five Star in connection
with the forgoing transactions. At December 31, 1993, $4,583,000 was outstanding

The MXL Loan Areement provides for a $1,500,000 revolving credit facility (the
"MXL Revolving Credit Facility") and a $4,500,000 term loan (The "MXL Term
Loan"). The MXL Revolving Credit Facility is a three year committed facility
which allows MXL to borrow amounts equal to 25% of Eligible Inventory (as
defined) and 80% of Eligible Receivables (as defined) at an interest rate of 1%
in excess of the prime rate. At December 31, 1993, the interest rate was 7%. As
of December 31, 1993, there were no borrowings under the MXL Revolving Credit
Facility and the balance of the MXL Term Loan was $4,125,000. The MXL Term Loan
is repayable in 10 quarterly payments of approximately $375,000, which commenced

than certain equipment) of MXL and by 815,625 shares of common stock of ISI
and 637,500 shares of common stock of GP, which were contributed to MXL in
connection with the forgoing transactions.

The Five Star Revolving Credit Facility and Five Star Term Loan and the MXL
Revolving Credit Agreement and MXL Term Loan are guaranteed by the Company. The
Agreements, among other things, limit the amount that Five Star and MXL may
borrow from other sources,the amount and nature of certain expenditures,
acquisitions and sales of assets, and the amount that Five Star and MXL can loan
or dividend to the Company. The agreements have several covenants, including
provisions regarding working capital, tangible net worth, leverage and cash flow
ratios.

(c) On October 3, 1991, GPS entered into an Amended and Restated Revolving
Credit and Term Loan and Security Agreement (the Agreement) with two banks. The
Agreement provided for a Term Loan of $5,000,000 and additional Revolving Credit
borrowings of up to $5,000,000. Borrowings under the Agreement were provided
equally by the participating banks, secured by accounts receivable, and bore
interest at rates set by such banks under options provided for in the Agreement.
Such Agreement, among other things, limited the amount that GPS may borrow from
other sources and the amount and nature of certain expenditures and required GPS
to maintain tangible net worth, working capital, cash flow, and debt ratios, as
defined in the Agreement. Term Loan borrowings were due in quarterly
installments which commenced December 31, 1991 and were to end on September 30,
1994.

On June 30, 1993, GPS replaced the above agreement with a new three year
$10,000,000 credit facility. The credit facility is secured by the accounts
receivable and fixed assets of GPS. The initial $5,000,000 of the credit
facility is fixed at an interest rate of 7.98% and the second $5,000,000 of the
credit facility bears interest at a rate equal to 1.25% in excess of the bank's
prime rate. At December 31, 1993, $5,650,000 was borrowed under the credit
facility.

(d) In August 1991, Eastern Electronics Manufacturing Corporation (Eastern)
assigned the remaining balance on its line of credit with a bank to a finance
company, with whom Eastern entered into a Security Agreement. Under the terms of

outstanding accounts receivable, as defined, at an interest rate of 5 1/2% over
the prime rate of interest (11.5% at December 31, 1993). At December 31, 1993,

7. Short-term borrowings (Continued)

(e)    On February 9, 1993, Duratek entered into a $7,000,000 Revolving Line of
Credit (the Line) and a $400,000 Loans to Facility (the Facility) for fixed
asset purchases with a commercial bank. On June 11, 1993, the Line was
increased to $7,750,000 and the Facility was increased to $750,000. Term Loans
under the Facility will be due over a 36 month period from the date of issue
and bear interest at the bank's prime rate plus 1 %. The Facility is secured
by the specific fixed assets financed under the Facility. The Line bears
interest at the bank's prime interest rate plus 1% and is secured by the
accounts receivable, inventory and property, plant and equipment of Duratek.
The Line requires Duratek to meet certain covenants concerning, among other
things, minimum tangible net worth, total liabilities to tangible net worth,
and profitability. It also contains limitations with respect to dividends or
other distributions to stockholders, mergers, acquisitions, and research and
development expenses. Short-term borrowings during 1992 were under an
agreement similar to the current agreement described above. At December 31,
1993, borrowings were $3,110,000 under the Line and $500,000 is outstanding
under the Facility.

(f)    In December 1992, the Company repurchased SFr. 1,264,000 of its
outstanding Swiss Bonds for a $466,000 Note, which bore interest at 1/2% per
month, due February 24, 1993. The Note was secured by 250,000 shares of the
Company's common stock. The principal amount of the Note could be reduced by
the proceeds from the sale of the common stock by the Company. At December 31,
1992, the balance of the Note, reduced for the proceeds from the sale of the
Company's common stock, was $183,000. The balance was repaid in February 1993.

the Expiration Date (August 19, 1993) was: a) 5% U.S. dollar denominated
Convertible Bonds of the Company due August 31, 1999 (the "New 5% Bonds") in a
principal amount of $130 and convertible into 30 shares of the Company's
Common Stock ("Common Stock"), b) 54 shares of Common Stock, c) 26 shares of

       On the Expiration Date the Company accepted the following amounts of

1,125,000 of the 5 3/4% Bonds due May 9, 1995, SFr. 2,765,000 of the 5 5/8%

$882,000 of the 7% Bonds due March 18, 1996. Under the terms of the Offer,
which included all unpaid accrued interest thereon, the Company issued the
following amounts of consideration to the exchanging bondholders a) 1,385,586

9. Long-term debt (Contiuned)

(b)    On December 20, 1989, in exchange for Swiss Francs (SFr.) 32,420,000
($20,318,000) of its 6% Convertible Swiss Bonds due March 7, 1995, SFr.
26,335,000 ($16,515,000) of its 5.75% Convertible Swiss Bonds due May 9, 1995,
and SFr. 26,685,000 ($16,734,000) of its 5.625% Convertible Swiss Bonds due
March 18, 1996, (collectively, the Old Bonds), each in the principal amount of
SFr. 5,000, plus all unpaid accrued interest thereon, the Company issued: (a)
SFr. 51,264,000 ($32,140,000) of its 8% Swiss Bonds due March 1, 1995, each in
the principal amount of SFr. 3,000, (the New Bonds) of which SFr. 7,401,000
are currently outstanding, (b) 17,088 Reset Warrants, each of which entitles
the holder to purchase 75 shares of the Company's common stock, at a price
determined by formula, exercisable until March 1, 1995, (c) 17,088 Common
Stock Warrants, each of which entitles the holder to acquire without further
consideration shares of the Company's common stock with a market value of SFr.
250, exercisable until March 1, 1995, and (d) SFr. 750 in cash.

       The Company recorded an original issue discount on the New Bonds of
40%, based upon exchange values estimated by the Swiss exchange agent.
Expenses of the exchange offer totaled $2,116,000. The discount and the
offering expenses, which have been deferred, are being amortized over the term
of the New Bonds.

(c)    On March 7, 1985, the Company issued, pursuant to a Swiss Public Bond
Issue Agreement, 6% Convertible Bonds due March 7, 1995 representing an
aggregate principal amount of SFr. 60,000,000, of which SFr. 8,635,000 are
currently outstanding (see (a) and (b) above). The outstanding bonds are
convertible into 148,522 shares of the Company's common stock at any time
prior to February 10, 1995 at a conversion price of approximately $39.15 per
share based on an exchange rate of SFr 1.485 per U.S. $1.00. In addition, on
May 9, 1985, the Company issued, pursuant to a second Swiss Public Bond Issue
Agreement, 5.75% Convertible Bonds due May 9, 1995, representing an aggregate
principal amount of SFr. 50,000,000, of which SFr. 3,520,000 are currently
outstanding (see (a) and (b) above). These outstanding bonds are convertible
into 75,328 shares of the Company's common stock at a conversion price of
$31.47 per share based on an exchange rate of SFr 1.485 per U.S. $1.00 at any
time prior to April 22, 1995. Expenses of both Swiss Public Bond Issues
totaled approximately $1,793,000 and at December 31, 1993 and 1992, the
unamortized balances of such expenses were $30,000 and $91,000, respectively.

                                     52

(d)    On March 18, 1986, the Company issued, pursuant to a third Swiss Public
Bond Issue Agreement, 5.625% Convertible Bonds payable in 1996, representing
an aggregate principal amount of SFr. 50,000,000, of which SFr. 4,735,000 are
currently outstanding (see (a) and (b) above). Additionally, the Company
issued 7% Dual Currency Convertible Bonds, payable in 1996, representing an
aggregate principal amount of SFr. 25,000,000, but payable at maturity at the
fixed amount of $15,000,000. The outstanding Bonds are convertible into
218,800 shares of the Company's common stock at any time prior to March 8,
1996 at a conversion price of $34.71 per share based on an exchange rate of
SFr 1.485 per U.S. $1.00. Under certain circumstances, the Company may redeem
all of the Bonds (but not a part only) at a redemption price equal to par
value. Expenses related to the issuance of the Bonds totaled approximately
$1,660,000 and at December 31, 1993 and 1992, the unamortized balances of such
expenses were $61,000 and $132,000, respectively. The Dual Currency Bonds were
issued as part of the Company's overall financing strategy, without any intent
to either speculate in foreign exchange or to hedge any existing foreign
currency exposure. It is the Company's policy to record periodic interest
expense on the Dual Currency Bonds at the then current exchange rate. At
December 31, 1993 and 1992, based on year end exchange rates, the effective
rates of interest would be approximately 8%. At December 31, 1993, the
effective rate of interest of approximately 8% would result in an additional
$33,000 of interest expense per year, through March 1996.

On August 10, 1990, the Company completed an Exchange Offer pursuant to which
it received $4,659,000 of its 7% Dual Currency Convertible Bonds due March 18,
1996 (Bonds). In exchange, the Company issued 540,444 shares of its Common
Stock and warrants to purchase 465,900 shares of the Common Stock, par value
$.01 per share, of ISI, currently the Company's 36% owned affiliate,
exercisable at a price of $6.88 per share until August 16, 1992. The Exchange
Offer was completed on August 10, 1990 and the Company recorded an
extraordinary gain of $1,477,000 on the early extinguishment of the Bonds.
During February 1992, ISI called the warrants, resulting in net proceeds to
ISI of $2,956,000 from the issuance of 432,600 shares of ISI common stock upon
exercise of the warrants.

In addition to the bonds exchanged (see (a) and (b) above), during 1993, 1992
and 1991 the Company repurchased a portion of each of the Swiss Public Bond
Issues as well as Dual Currency Convertible Bonds. Extraordinary gains from
the early extinguishment of the Bonds in all such transactions amounted to
$1,819,000 (net of income taxes), $1,662,000 and $2,037,000, respectively.

9. Long-term debt (Continued)

(e)    During the third quarter of 1987, the Company issued $12,500,000 of
Subordinated Debentures (Debentures) which mature in 1997. Each $100 principal
amount Debenture was sold with warrants to purchase four shares of the
Company's common stock at a price of $18.50 per share. Expenses of the
offering amounted to approximately $1,908,000 and as of December 31, 1993 and
1992, the unamortized balances of such expenses were $432,000 and $550,000. In
connection with the terms of the Debentures, the Company is subject to certain
covenants which limit the amount that may be used for the payment of dividends
and for the purchase of the Company's outstanding equity securities (common or
Class B). In September 1990, under the terms of an Indenture, the Debentures
became exchangeable for the Company's Common Stock, for the remaining term of
the Debentures, at a price of approximately $5.00 per share. In 1993 and 1992,
$82,000 and $179,000, respectively, of Debentures were converted into 16,579
and 35,933 shares, respectively, of the Company's Common Stock. At December
31, 1993, the Debentures are convertible into approximately 1,374,000 shares
of the Company's Common Stock.

(f)    In March 1987, the Company and Ryder International Corporation (Ryder)
agreed to a settlement of litigation relating to the Company's Caridex/R/
system. Under the terms of the settlement agreement, the Company agreed to pay
Ryder (i) $1,000,000 in cash; (ii) $2,000,000 in common stock of the Company
(133,333 shares, valued at $2,000,000 were issued from treasury stock during
1987, and subsequently repurchased for $2,000,000 during 1988); and (iii)
$300,000 per year (in cash or common stock of the Company) for a ten year
period commencing January 15, 1988, the present value of which is discounted
at 10%, and included in long-term debt.

(g)    In May 1987, the Company and George K. Burke, Sr. and Concetta J. Burke
(the Burkes) settled a lawsuit asserting various claims for relief against the
Company with respect to several agreements concerning the marketing and
development of the EPIC/R/ system of intravenous devices, which the Company had
discontinued in December 1983. As a result of the settlement the Burkes
received $500,000 in cash upon execution of the settlement agreement and
received $250,000 a year (in cash or common stock of the Company) for a five
year period commencing in May 1988. In 1987, the Company recorded an
additional loss from this discontinued operation totaling $1,500,000,
representing the present value of the amounts due the Burkes plus the costs
relating to the litigation and settlement. The final payment was made in the
common stock of the Company in 1992.

(h)    During May 1983, ISI, a currently 36% controlled affiliate of the
Company, completed the sale of a 9.6% $1,450,000 Industrial Revenue Bond to
the New Jersey Economic Development Authority. The net proceeds were used to
pay for laboratory construction and equipment. The terms of the bond indenture
call for annual principal installments of $195,000 through 1993.

(i)    In March 1990, ISI borrowed $4,200,000 from a subsidiary of a bank at
an effective interest rate of 12.4% principally for the expansion of its
manufacturing facility. The loan calls for monthly payments of $41,500 for
months 1 to 24, which is comprised of interest only, and $139,500 (principal
and interest) for months 25 to 60. The loan is secured by certain equipment of
ISI and is guaranteed by the Company.

(j)    In December 1991, ISI issued a $459,000 note to Purdue Pharma L.P., an
affiliate of The Purdue Frederick Company, its marketing partner. The note
bears interest at 7.5% per annum, and required payment of interest and
principal on December 31, 1993, which was subsequently extended to April 27,
1994. As a result of the Exchange Offer (See (a)), ISI is currently accounted
for on the equity basis.

Aggregate annual maturities of long-term debt outstanding at December 31, 1993
for each of the next five years are as follows (in thousands):

              1994                                  $  4,220

GPS Technologies, Inc. is a high technology service company that assists
industry and the Navy in maximizing the effectiveness of their equipment and
facilities through the rigorous training of technical personnel and the
development and implementation of operational procedures and maintenance
programs. GPS conducts certain of its services using power plant training
simulators, the majority of which are owned by its clients. However, at
December 31, 1993, two simulators are owned by wholly owned subsidiaries of
GPS.

10. Investment in finance subsidiaries (Continued)

Through these subsidiaries, GPS has entered into long-term agreements with two
domestic utilities to provide nuclear power plant simulator training services
along with the attendant nuclear power plant training simulators and related
training equipment. Under the provisions of the agreements, the subsidiaries
obtained non-recourse long-term financing from a bank to finance the purchase
of the simulators and training equipment. The agreements provide that the
subsidiaries are compensated, in part, for use of the simulators on
essentially a lease financing basis.

The agreements provide that the payments by the utilities will enable the
subsidiaries to recover the cost of the simulators plus interest at floating
rates which range from prime to 115% of prime, as well as the cost of
simulator replacement parts, taxes, and insurance. Such amounts will be
sufficient to fully service the related long-term debt discussed below. All
training services are performed by GPS personnel and are billed at established
hourly rates. Revenues for these services are recognized by GPS.

Under the agreements, the utilities have options to purchase the simulators
and other training equipment at the end of the loan terms.

Non-recourse long-term debt relating to the simulators consists of the
following (in thousands):

prime rate to 115% of the bank's prime rate, and are payable in monthly
installments over periods of up to 15 years from the initial dates of each of
the loans.

The loans are secured by the equipment and all rights under the agreements
with the utilities. Under these agreements, GPS has agreed to guarantee the
service performance with the utilities but has not guaranteed the obligations
of its subsidiaries under the loan agreements. GPS has also agreed to maintain
a minimum debt to equity ratio, a minimum tangible net worth and a minimum
working capital, as defined.

11. Common stock issued subject to repurchase obligation

During the fourth quarter of 1993, the Company entered into several privately
negotiated agreements (the Agreements), pursuant to which it reacquired
previously outstanding Swiss Bonds in exchange for newly issued common stock.
In addition to common stock, the Company issued to the exchanging bondholder
in each transaction a non-negotiable, non interest bearing promissory note
(the Note) in a principal amount equal to the market value of the common stock
issued in the exchange. The recipient in each transaction obtained the rights,
exercisable within approximately a one year period from the date of the
Agreement, to sell, retain, or return to the Company the common stock
received, in whole or in part. Net proceeds of any sales of common stock by
the recipient during the period reduces the amount due under the Note, and
sales of common stock for net proceeds equal to or in excess of the principal
amount of the Note would cause the Note to be deemed as paid in full. Any
excess proceeds of sale of the stock over the principal amount of the Note are
retained by the stockholder.

11. Common stock issued subject to repurchase obligation (Continued)

The Company has accounted for the issuance of the common stock as permanent
equity to the extent of the proceeds of subsequent sales of stock by the
recipients, and as temporary equity for the balance of the market value of the
common stock issued. The Notes serve as a guarantee of the amounts which may
be refundable to the recipients of the common stock under the Agreement. The
Company's maximum repurchase or refund obligation under these Agreements as of
December 31, 1993 aggregated $4,242,000.

13. Disposal of business

      On April 8, 1991, the Company transferred substantially all the assets of
its National Patent Medical Division to a new partnership, National Patent
Medical Partnership, L.P. (NPM). In return, the Company received a 49%
interest in the partnership, $7,200,000 in cash and a $1,800,000 note at the
prime rate of interest plus 1/2%. The note is due in two equal installments in
1996 and 1997. In addition, the new partnership repaid $4,000,000 of short-
term borrowings attributable to the National Patent Medical Division. The
Company did not recognize any gain or loss as a result of this transaction.
NPM is involved in the manufacturing and distribution of first-aid products,
surgical dressings and other disposable hospital products. The financial
position and results of operations of NPM are included in the consolidated
accounts of the Company for all periods presented through April 8, 1991, the
date that the Company's ownership of NPM fell below 50%. Since then, the
accounts of NPM have not been consolidated with those of the Company. NPM's
net sales and operating loss through April 8, 1991 were $11,129,000 and
$(81,000), respectively. In November 1992, NPM Healthcare Products, Inc.
(NPMH), a successor to NPM, completed an initial public offering. As a result
of the public offering, the Company received approximately $4,500,000 in net
proceeds, which approximated the carrying value of the shares sold.

The Company has accounted for its investment in NPMH on the equity basis for
the period from April 9, 1991, when its equity in NPMH fell below 50%, to
December 31, 1991, and for the period from January 1, 1992 to October 1992,
when its equity fell to approximately 14% as a result of the public offering.
The Company's share in the net income (loss) of NPMH for the periods ended
December 31, 1991 and October 31, 1992, amounted to $(805,000) and $35,000,
respectively, after amortization of the underlying goodwill. At December 31,
1993, the Company's investment in NPMH was $3,914,000. In 1994, NPMH changed
its name to American White Cross, Inc.

14. Employee benefit plans

The Company had a Defined Benefit Pension Plan (the Plan) for employees of
certain divisions and subsidiaries. Benefits were based primarily on years of
service and a fixed rate of benefits per year of service. Contributions were
intended to provide not only for benefits attributed to service to date but
also for those expected to be earned in the future.

Effective December 31, 1991, the Plan benefits were frozen. Accrued vested
benefits will be paid to terminated participants in the form of a lump sum
distribution in cases where the accrued vested benefit is less than $3,500.
Terminated participants can elect a lump sum distribution if the accrued
vested benefit is greater than $3,500 but less than $7,500.

In the event that the accrued vested benefit exceeds the $7,500 payable limit
as outlined in the Plan, payment will be deferred until a terminated vested
participant reaches age 65 or elects early retirement at an earlier date, at
age 60 or later. The pension expense amounted to $377,000, $23,000 and
$552,000, for 1993, 1992 and 1991, respectively.

The following table sets forth the funded status of the plan and the amount
recognized in the Company's Consolidated Balance Sheets (in thousands):

14. Employee benefit plans (Continued)

The Company's assumptions used as of December 31, 1993, 1992, and 1991 in
determining the pension cost and pension cost liability shown above were as
follows:
                                                             Percent

Effective March 1, 1992, the Company adopted the 1992 401(K) Savings Plan (the
Savings Plan). Effective December 31, 1991, the Plan participants would no
longer accrue benefits under the Defined Benefit Pension Plan, but became
eligible to participate in the Company's Savings Plan.

The Company's Savings Plan is for employees who have completed one year of
service; however, past vesting service credit was recognized for employees who
participated in the Savings Plan at the date of initial enrollment, March 1,
1992.

The Savings Plan permits pre-tax contributions to the Savings Plan by
participants pursuant to Section 401(K) of the Internal Revenue Code of 2% to
6% of base compensation. The Company matches 40% of the participants' eligible
contributions based on a formula set forth in the Savings Plan. Participants
are fully vested in their contributions and may withdraw such contributions at
time of employment termination, or at age 59 or earlier in the event of
financial hardship. Amounts otherwise are paid at retirement or in the event
of death or disability. Employer contributions vest at a rate of 20% per year.

The Savings Plan is administered by a trustee appointed by the Board of
Directors of the Company and all contributions are held by the trustee and
invested at the participants' direction in various mutual funds. The expense
associated with the Savings Plan was $236,000 and $214,000 in 1993 and 1992,
respectively. During the first quarter of 1993, the Company adopted Statement
of Financial Accounting Standard No. 106 (SFAS No. 106), "Employers'
Accounting for Post Retirement Benefits Other Than Pensions". This statement
requires that the expected cost of post retirement benefits be fully accrued
by the first date of full benefit eligibility, rather then expensing the
benefit when payment is made. As the Company generally does not provide post
retirement benefits, other than pension, the new statement did not have any
material effect on the Company's financial condition or results of
operations.

</TABLE> 

In 1991, despite the Company's $1,157,000 income before income taxes, as well
as its $2,037,000 gain from extraordinary item, no Federal income tax expense
was recognized. This is due principally to significant permanent differences
between financial and tax reporting of 1991 transactions, including the
elimination for tax purposes of the $18,844,000 gain on the sale of GP stock
net of a gain recognized only for tax purposes upon ISI ceasing to be a member
of the Company's consolidated Federal income tax return group on May 31, 1991.
The income tax expense for 1991 of $549,000 represents state and local income
taxes.

In 1992, the Company's loss before income taxes exceeded its gains from
extraordinary items; therefore, no income tax expense applicable to such
extraordinary gains was recognized. The income tax expense for 1992 of
$427,000 represents state and local income taxes.

In 1993, the Company recorded an income tax benefit of $1,043,000, of which
$973,000 relates to Federal income taxes, in continuing operations as a result
of the income tax expense allocated to the extraordinary gain recognized on
the early extinguishment of debt under the provisions of FASB No. 109.

                                     62
<PAGE>
 
As of December 31, 1993, the Company has approximately $22,520,000 of
consolidated net operating loss carryovers for Federal income tax return
purposes, which expire beginning in the years 2002 through 2008. In addition,
the Company has approximately $2,784,000 of available credit carryovers.

Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS No. 109).
This statement requires that deferred income taxes be recorded following the
liability method of accounting and adjusted periodically when income tax rates
change. Adoption of the new Statement did not have a material effect on the
Company's financial condition or results of operations since the Company does
not carry any deferred tax accounts on its balance sheet.

A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax asset will not be realized. The Company has
determined, based on the Company's recent history of annual net losses, that a
full valuation allowance is appropriate.

The Company has, as of December 31, 1993, deferred tax assets of approximately
$19,267,000, deferred tax liabilities of approximately $5,909,000 and a
valuation allowance of approximately $13,358,000.

and 1991 were reserved for issuance to these same two officers.

The holders of common stock are entitled to one vote per share and the holders
of Class B capital stock are entitled to ten votes per share on all matters
without distinction between classes, except when approval of a majority of each
class is required by statute. The Class B capital stock is convertible at any
time, at the option of the holders of such stock, into shares of common stock on
a share-for-share basis. Common shares reserved for issuance at December 31,

Identifiable assets by industry segment are those assets that are used in the
Company's operations in each segment. Corporate and other assets are principally
cash and cash equivalents, marketable securities and un-allocated intangibles.

18. Fair value of financial instruments

The carrying value of financial instruments including cash, short-term
investments, accounts receivable,restricted cash, accounts payable and short-
term borrowings approximate estimated market values because of short maturities
and interest rates that approximate current rates.

The carrying values of investments, other than those accounted for on the equity
basis, approximate fair values based upon quoted market prices. The investments
for which there is no quoted market price are not significant.

The estimated fair value for the Company's major long-term debt components are
as follows (in thousands):

Limitations. Fair value estimates are made at a specific point in time, based on
relevant market information and information about the financial instrument.
These estimates are subjective in nature and involve uncertainties and matters
of significant judgement and therefore cannot be determined with precision.
Changes in assumptions could significantly affect the estimates.

the Company at a price of $1.90 per share were issued to certain employees and
officers of the Company. Through December 31, 1993, 28,600 options under the
plan were exercised, 57,500 were cancelled, and at December 31, 1993, 369,750
options are currently exercisable. At December 31, 1993, the Company owned
approximately 66% of Duratek.

The Company is party to several lawsuits and claims incidental to its
business, including claims regarding environmental matters, one of which is in
the early stages of investigation. It is not possible at the present time to
estimate the ultimate legal and financial liability, if any, of the Company in
respect to such litigation and claims; however, management believes that the
ultimate liability, if any, will not have a material adverse effect on the
Company's Consolidated Financial Statements.

20. Subsequent event

On January 13, 1994, GP signed a Letter of Intent with GPS and the Company to
acquire substantially all of the operating assets of GPS and certain of its
subsidiaries. The Company currently owns approximately 92% of the outstanding
common stock of GPS and approximately 28% of the outstanding common stock of
GP. On March 28, 1994, the Board of Directors of both GP and GPS approved the
transaction. The parties are currently negotiating the terms of a definitive
agreement and the transaction is anticipated to close as soon as practicable
in the second half of 1994, if all necessary approvals are obtained and
conditions satisfied.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


20.  Subsequent event (Continued)

The purchase price has a current present value of approximately $36 million
based on current market prices. The purchase price will be payable to GPS as
follows: $10 million cash; 3.5 million shares of GP common stock valued at
approximately $13,500,000 (based upon the price per share of GP common stock
prior to the announcement of the transaction which was $3.875); warrants to
acquire 1,000,000 shares of GP common stock at $6.00 per share valued at
approximately $1,300,000; warrants to acquire up to 475,644 additional shares
of GP common stock at $7 per share valued at approximately $500,000; a $15
million ten-year senior subordinated debenture valued at approximately
$10,700,000, accruing interest at 6% per annum, interest payable only for the
first five years, with 70% of principal payable in equal quarterly
installments during the remaining five years until maturity.

Portions of the cash and stock consideration of the purchase price will be (a)
used to repay outstanding bank debt of $5,650,000 (as of December 31, 1993)
and long-term debt of GPS of $8,809,000 (as of December 31, 1993) to be repaid
to the Company. In addition, $1.5 million of Debentures are held in escrow for
the benefit of GP in connection with certain indemnification obligations.

The transaction is contingent upon the occurrence of certain events,
including, without limitation, approval of the transaction by the stockholders
of both GPS and GP.

The Company anticipates that if the aforementioned transaction is consummated,
it will own approximately 52% of the outstanding common stock of GP, and if
the Company were to exercise all of its warrants, it will own approximately
58% of the outstanding common stock of GP.

The Company will account for this transaction as a purchase of GP. The Company
believes that any gain or loss to be recognized on this transaction would not
be significant, since the transaction (based upon the currently contemplated
assets to be sold), if consummated, is expected to be consummated at or near
the carrying value of the underlying assets.

Although an agreement in principle has been reached, there can be no assurance
that a definitive agreement will be successfully negotiated and signed, or
that the transaction will close as anticipated.

(2)  The above is a note receivable recorded on the balance sheet of Interferon
     Sciences, Inc. (ISI). As a result of the Company's interest in ISI falling
     below 50% in 1993, ISI is accounted for on the equity method, and
     accordingly the balance of $150,000 at December 31, 1993 is not included in
     the Company's financial statements. During 1993, $50,000 of the note
     receivable was repaid by the borrower.

          Note (c):    COMMITMENTS AND CONTINGENCIES

          The Company has several noncancellable leases which
cover real
          property and machinery and equipment.  Such leases
expire at
          various dates with, in some cases, options to extend
their terms.

          Minimum rentals under long-term operating leases are as
follows
          (in thousands):

</TABLE>



          Several of the leases contain provisions for rent
escalation
          based primarily on increases in real estate taxes and
operating
          costs incurred by the lessor.

          The Company is party to several lawsuits incidental to
its
          business.  It is not possible at the present time to
estimate the
          ultimate legal and financial liability, if any, of the
Company
          with respect to such litigation; however, management
believes
          that the ultimate liability, if any, will not have a
material
          adverse effect on the Company's Financial Statements.

          National Patent Development Corporation


Under date of March 30, 1994, we reported on the consolidated balance sheet of
National Patent Development Corporation and subsidiaries as of December 31, 1993
and 1992, and the related consolidated statements of operations, changes in
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1993, as contained in the annual report on Form 10-K
for the year 1993. In connection with our audits of the aforementioned
consolidated financial statements, we also have audited the related financial
statement schedules as listed in the accompanying index. These financial
statement schedules are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statement schedules
based on our audits.

In our opinion, the related financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein.

3.   Subsequent event

     On April 7, 1994, General Physics Corporation (GP) entered into an
agreement with GPS Technologies, Inc. (GPS) and the Company to acquire
substantially all of the operating assets of GPS and certain of its
subsidiaries. The Company currently owns approximately 92% of the outstanding
common stock of GPS and approximately 28% of the outstanding common stock of
GP. GP agreed to pay GPS a purchase price with current present value of
approximately $36 million based on current market prices. The purchase price
will be payable to GPS as follows: $10 million in cash; 3.5 million shares of
GP common stock valued at approximately $13,500,000 (based upon the price per
share of GP common stock prior to the announcement of the transaction which
was $3.875); warrants to acquire 1,000,000 shares of GP common stock at $6.00
per share valued at approximately $1,300,000; warrants to acquire up to
475,644 additional shares of GP common stock at $7 per share valued at
approximately $500,000; and 6% Senior Subordinated Debentures due 2004 (the
"Debentures"), in the aggregate principal amount of $15,000,000, valued at
approximately $10,700,000. The values assigned to each component of
consideration were based upon discussions with the independent investment
banker to the Independent Committee of GP and the investment banker to GPS.
Portions of the cash and stock consideration of the purchase price will be (a)
used to repay outstanding bank debt of $5,650,000 and long-term debt of GPS of
$8,809,000 to be repaid to the Company and (b) held in escrow.

     The transaction is contingent upon the occurrence of certain events,
including, without limitation, the approval of the transaction by the
stockholders of GP and GPS. The transaction is anticipated to close as soon as
practicable in the second half of 1994, if all necessary approvals are
obtained and conditions satisfied. The Company anticipates that, if the
aforementioned transaction is consummated, it will own approximately 52% of
the outstanding common stock of GP, and if the Company were to exercise all of
its warrants, it would own approximately 58% of the outstanding common stock
of GP. The Company will account for this transaction as a purchase by the
Company of GP.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                          AND RESULTS OF OPERATIONS

                            RESULTS OF OPERATIONS

     The Company had a loss before income taxes and extraordinary item of
$(2,394,000) for the quarter ended March 31, 1994 compared to $(2,939,000) for
the quarter ended March 31, 1993. During the first quarter of 1994, the
Company realized net foreign currency transaction losses of $(897,000), as
compared to a gain of $670,000 for the first quarter of 1993 as a result of
the weakness of the U.S. dollar relative to the Swiss Franc and the Company's
decision not to hedge its Swiss currency obligations. At March 31, 1994, there
was an aggregate of SFr. 26,318,000 of Swiss denominated indebtedness
outstanding, of which SFr. 23,823,000 represents principal amount outstanding
and SFr. 2,495,000 represents interest accrued thereon. Foreign currency
valuation fluctuations may adversely affect the results of operations and
financial condition of the Company. In order to protect itself against
currency valuation fluctuations, the Company has at times swapped or hedged a
portion of its obligations denominated in Swiss Francs. At March 31, 1994, the
Company had not hedged its Swiss Franc obligations. If the value of the Swiss
Franc to the U.S. dollar increases, the Company will recognize transaction
losses on its Swiss Franc obligations. On March 31, 1994, the value of the
Swiss Franc to the U.S. dollar was 1.4120 to 1. There can be no assurance that
the Company will be able to swap or hedge obligations denominated in foreign
currencies at prices acceptable to the Company or at all. The Company will
continue to review this policy on a continuing basis.

     The foreign currency transaction loss was offset by reduced interest
expense due to a reduction in long-term debt, as well as improved operating
results within the Optical Plastics and Physical Science Groups. The Optical
Plastics Group achieved improved operating results due to increased sales and
gross margin percentages. The Physical Science Group achieved improved results
due to a favorable change in the mix of products and services provided to its
customers.

Sales
- -----

     For the quarter ended March 31, 1994, consolidated sales increased by
$268,000 to $45,232,000 from the $44,964,000 in the corresponding quarter of
1993. The increased sales were the result of increased sales within the
Distribution and Optical Plastics Groups, offset by reduced sales by the
Physical Sciences Group due to the end of a long-term staff augmentation
contract at GTS Duratek, Inc. (Durtek).




                                          8

Gross margin
- ------------

     Consolidated gross margin of $8,247,000, or 18%, for the quarter ended
March 31, 1994, increased by $2,054,000 compared to the consolidated gross
margin of $6,193,000, or 14%, for the quarter ended March 31, 1993. The
increased gross margin in 1994 was primarily the result of increased sales and
gross margin percentage achieved by the Optical Plastics Group, as well
increased gross margin achieved by the Physical Science Group due to the
higher gross margin generated by Duratek's Environmental Services business and
a more profitable mix of services generated by GPS Technologies, Inc.

Selling, general and administrative expenses
- --------------------------------------------

     For the three months ended March 31, 1994, selling, general and
administrative (SG&A) expenses were $8,198,000 compared to the $8,297,000
incurred in the first quarter of 1993. The decrease in SG&A for the first
quarter of 1994 was the result of ISI being accounted for on the equity method
since the third quarter of 1993, partially offset by increased costs incurred
by the Distribution, Optical Plastics and Physical Sciences Groups.

Interest expense
- ----------------

     For the three months ended March 31, 1994, interest expense was
$1,503,000 compared to $2,473,000 for the three months ended March 31, 1993.
The decreased interest expense for the quarter was the result of reduced long-
term debt.

Investment and other income, net
- --------------------------------

     Investment and other income, net of $(752,000) for the quarter ended
March 31, 1994, decreased by $2,660,000 as compared to $1,908,000 for the
first quarter of 1993. The reduced investment and other income was principally
due to the effect of the following two factors; $(897,000) and $670,000 of
foreign currency transaction gains (losses), for the quarters ended March 31,
1994 and 1993, respectively, and a loss of $(770,000) realized in the quarter
ended March 31, 1994, on the share of losses of 20% to 50% owned subsidiaries,
compared to $175,000 earned in the quarter ended March 31, 1993, as a result
of the results of Interferon Sciences, Inc. (ISI) being accounted for on the
equity basis since the third quarter of 1993. For the quarter ended March 31,
1994, the Company's share of ISI's loss was $845,000. In the quarter ended
March 31, 1993, ISI was included in the consolidated results of the Company
and its loss was therefore not reflected in Investment and other income, net.

                       LIQUIDITY AND CAPITAL RESOURCES

     The Company believes that it has sufficient cash, cash equivalents and
borrowing availability under existing and potential lines of credit to satisfy
its cash requirements until the first scheduled maturity of its Swiss Franc
denominated indebtedness on March 1, 1995. However, in order for the Company
to meet its long-term cash needs, which include the repayment of $13,518,000
of Swiss Franc denominated indebtedness scheduled to mature in 1995 and
$7,279,000 of Swiss Franc denominated indebtedness which is scheduled to
mature in 1996, the Company must obtain additional funds from among various
sources. The Company has historically reduced its long-term debt through the
issuance of equity securities in exchange for long-term debt. In addition to
its ability to issue equity securities, the Company believes that it has
sufficient marketable long-term investments, as well as the ability to obtain
additional funds from its operating subsidiaries and the potential to enter
into new credit arrangements. The Company reasonably believes that it will be
able to accomplish some or all of the above transactions in order to fund the
scheduled repayment of the Company's long-term Swiss debt in 1995.

     At March 31, 1994, the Company had cash and, cash equivalents totaling
$9,848,000. GPS Technologies, Inc. and GTS Duratek, Inc. had cash and, cash
equivalents of $392,000 at March 31, 1994. The minority interests of these two
companies are owned by the general public, and therefore the assets of these
subsidiaries have been dedicated to the operations of these companies and may
not be readily available for the general corporate purpose of the parent.

               QUALIFICATION RELATING TO FINANCIAL INFORMATION

                               March 31, 1994




     The financial information included herein is unaudited. In addition, the
financial information does not include all disclosures required under
generally accepted accounting principles because certain note information
included in the Company's Annual Report has been omitted; however, such
information reflects all adjustments (consisting solely of normal recurring
adjustments) which are, in the opinion of management, necessary for a fair
statement of the results for the interim periods. The results for the 1994
interim period are not necessarily indicative of results to be expected for
the entire year.

                                                       April 28, 1994
                                                       New York, New York
              

                                   PROXY STATEMENT
             
               The accompanying Proxy is solicited by and on behalf of the
          Board of Directors of National Patent Development Corporation, a
          Delaware corporation (the "Company"), for use only at the Annual
          Meeting of Stockholders to be held at The Brunswick Hilton, Three
          Tower Center Boulevard, East Brunswick, New Jersey on the 8th day
          of June, 1994 at 1:30 P.M., Eastern Standard Daylight Savings
          Time, and at any adjournments thereof. The approximate date on
          which this Proxy Statement and the accompanying Proxy were first
          given or sent to security holders was April 28, 1994. 
              
               Each Proxy executed and returned by a stockholder may be
          revoked at any time thereafter, by written notice to that effect
          to the Company, attention of the Secretary, prior to the Annual
          Meeting, or to the Chairman of, or the Inspectors of Election, in
          person, at the Annual Meeting, or by the execution and return of
          a later-dated Proxy, except as to any matter voted upon prior to
          such revocation. 
             
               The Proxies in the accompanying form will be voted in
          accordance with the specifications made and where no
          specifications are given, such Proxies will be voted FOR the six
          nominees for election as directors named herein, FOR the
          amendment to the Company's Restated Certificate of Incorporation
          to increase the total number of shares of common stock which the
          Company shall have authority to issue, and FOR the approval of
          the selection of KPMG Peat Marwick as auditors. In the discretion
          of the proxy holders, the Proxies will also be voted FOR or
          AGAINST such other matters as may properly come before the
          meeting. The management of the Company is not aware that any
          other matters are to be presented for action at the meeting.
          Although it is intended that the Proxies will be voted for the
          nominees named herein, the holders of the Proxies reserve
          discretion to cast votes for individuals other than such nominees
          in the event of the unavailability of any such nominee.  The
          Company has no reason to believe that any of the nominees will
          become unavailable for election. The Proxies may not be voted for
          a greater number of persons than the number of nominees named.
          The election of directors will be determined by a plurality of
          the votes of the shares of common stock, par value $.01 per share
          (the "Common Stock") and Class B Capital Stock, par value $.01
          per shares (the "Class B Stock") present in person or represented
<PAGE>
 
          by proxy at the Annual Meeting and entitled to vote on the
          election of directors. A majority of the votes represented by the
          outstanding shares of Common Stock and a majority of the votes
          represented by the outstanding shares of Class B Stock, each
          voting separately as a class, is required to approve the proposal
          to amend the Restated Certificate of Incorporation to increase
          the total number of shares of Common Stock which the Company
          shall have authority to issue, while approval of the selection of
          auditors for the current year will require the affirmative vote
          of holders of Common Stock and Class B Stock representing a
          majority of the outstanding shares present in person or
          represented by proxy. Accordingly, in the case of shares that are
          present or represented at the Annual Meeting for quorum purposes,
          not voting such shares for a particular nominee for director,
          including by withholding authority on the Proxy, will not operate
          to prevent the election of such nominee if he or she otherwise
          receives affirmative votes; with respect to the approval of the
          Amendment to the Company's Restated Certificate of Incorporation,
          an abstention will operate to prevent approval of the item to the
          same extent as a vote against approval, and a broker "non-vote"
          (which results when a broker holding shares for a beneficial
          owner has not received timely voting instructions on certain
          matters from such beneficial owner) will effect the outcome of
          the vote the same as a negative vote with respect to the approval
          of the Amendment to the Company's Restated Certificate of
          Incorporation.
              
                                  VOTING SECURITIES
             
               The Board of Directors has fixed the close of business on
          April 15, 1994 as the record date for the determination of
          stockholders entitled to receive notice of and to vote at the
          Annual Meeting. The issued and outstanding stock of the Company
          on April 15, 1994 consisted of 20,310,706 shares of Common Stock,
          each entitled to one vote, and 250,000 shares of Class B Stock,
          each entitled to ten votes. A quorum of the stockholders is
          constituted by the presence, in person or by proxy, of holders of
          record of Common Stock and Class B Stock representing a majority
          of the number of votes entitled to be cast. The only difference
          in the rights of the holders of Common Stock and the rights of
          holders of Class B Stock is that the former class has one vote
          per share and the latter class has ten votes per share. The
          Class B Stock is convertible at any time into shares of Common
          Stock on a share for share basis at the option of the holders
          thereof. 
              
                           PRINCIPAL HOLDERS OF SECURITIES

               As of March 1, 1994, no person was known to the Company to
          own beneficially more than 5% of the Common Stock or Class B
          Stock of the Company except as set forth below.

               The following table shows as of such date the Class B Stock
          beneficially owned directly by Mr. Jerome I. Feldman, President
          and Chief Executive Officer and a director of the Company, and
          Mr. Martin M. Pollak, Executive Vice President and Treasurer and
          a director of the Company (for information with respect to the
          shares of Common Stock beneficially owned by Messrs. Feldman and
          Pollak, see "Security Ownership of Directors and Named Executive
          Officers"):

                      New York, NY 10019

          (1)Includes 775,000 shares each for Messrs. Feldman and Pollak
          which they currently have the right to purchase pursuant to the
          exercise of stock options. 

          (2)Percentage could increase up to approximately 88% if either
          individual exercised all of his stock options and the other
          individual did not exercise any. 

               Based upon the Common Stock and Class B Stock of the Company
          outstanding at March 1, 1994, Mr. Feldman and Mr. Pollak
          controlled approximately 13% of the voting power of all voting
          securities of the Company. This percentage for Mr. Feldman and
          Mr. Pollak would increase to approximately 51% if they exercised
          all the presently outstanding options to purchase shares of the
          Common Stock and Class B Stock of the Company held by them. 

               On March 26, 1986, Mr. Feldman and Mr. Pollak entered into
          an agreement (i) granting each other the right of first refusal
          over the sale or hypothecation of the Class B Stock and options
          to purchase Class B Stock now owned or subsequently acquired by
          each of them and (ii) in the event of the death of either of them
          granting the survivor a right of first refusal over the sale or
          hypothecation of the Class B Stock or options to acquire shares
          of Class B Stock held by the estate of the decedent. The
          aforesaid right of first refusal is for the duration of the life
          of the survivor of Mr. Feldman or Mr. Pollak.

          conversion of bonds issued with the Company's 12% Subordinated
          Debentures Due 1997. Mr. Feldman disclaims beneficial ownership of
          the 2,414 shares issuable upon conversion of bonds held by his wife
          pursuant to the Debentures. Messrs. Feldman, Pollak and Gould
          disclaim beneficial ownership of 8,447, 23,006 and 100 shares,

          (3) Of the directors and executive officers of the Company, the
          following beneficially own the number of shares of common stock of
          Interferon Sciences, Inc. ("Interferon") indicated: Jerome I.
          Feldman 458,300 (2.31%); Martin M. Pollak 442,500 (2.23%); Ogden R.
          Reid 5,100 (.026%); Scott N. Greenberg 145,000 (.74%); Roald
          Hoffmann 2,000 (.010%) and Lawrence M. Gordon 162,500 (.83%). These

          shares for Messrs. Feldman, Pollak, Reid, Greenberg, Hoffmann and
          Gordon, respectively, which are subject to currently exercisable
          stock options. In addition, all directors and executive officers as
          a group beneficially own 1,215,400 shares, of which 1,194,500 shares
          are subject to currently exercisable stock options. Certain members
          of the families of Messrs. Feldman and Pollak hold 5,800 and 1,000
          shares, respectively, as to which Messrs. Feldman and Pollak
          disclaim beneficial ownership. Mr. Feldman and Mr. Pollak through
          their ownership of the Company's Common Stock, may be deemed to
          beneficially own an aggregate of 6,975,148 shares of Common Stock of
          Interferon beneficially owned by the Company and Five Star Group,
          Inc. ("Five Star") and MXL Industries, Inc. ("MXL"), wholly owned
          subsidiaries of the Company. However, Mr. Feldman and Mr. Pollak
          disclaim benefical ownership of such 6,975,148 shares (7,433,448 and
          7,417,648 shares in the aggregate for Mr. Feldman and Mr. Pollak,
          respectively). The total number of shares owned by all directors and
          executive officers of the Company as a group (other than Messrs.
          Feldman and Pollak) is 1.6% of the outstanding shares of
          Interferon's common stock. All such persons have sole voting and
          investment power as to all shares except as indicated.

          Board Compensation Committee Report on Executive Compensation

               During the year ended December 31, 1993, the Company did not
          have a Compensation Committee. Accordingly, the full Board of
          Directors is responsible for determining and implementing the
          compensation policies of the Company.          
             
               The executive compensation policies are designed to offer
          competitive compensation opportunities for all executives which are
          based on personal performance, individual initiative and
          achievement, and assist the Company in attracting and retaining
          qualified executives.          
              
             
               The Board also endorses the position that stock ownership by
          management and stock-based compensation arrangements are beneficial
          in aligning managements' and shareholders' interests in the
          enhancement of shareholder value and recommends to the Stock Option
          Committee the grant of stock options to executive officers whose
          performance has a significant effect on the success of the Company.
              
               Compensation paid to the Company's executive officers generally
          consists of the following elements: base salary, annual bonus and
          grant of stock options. The compensation for Mr. Pollak is
          determined on the same basis as that of Mr. Feldman, the Chief
          Executive Officer. The compensation for the other executive officers
          of the Company is determined by a consideration of each officer's
          initiative and contribution to overall corporate performance, the
          officer's managerial abilities and the performance in any special
          projects that the officer may have undertaken. Competitive base
          salaries that reflect the individual's level of responsibility are
          important elements of the Company's executive compensation
          philosophy. Subjective considerations of individual performance are
          considered by the Board in establishing annual bonuses and other
          incentive compensation.

               The Company has certain broad-based employee benefit plans in
          which all employees, including the named executives are permitted to
          participate on the same terms and conditions relating to eligibility
          and subject to the same limitations on amounts that may be
          contributed. In 1993, the Company also made a matching contribution
          to the 401(k) Savings Plan for those participants.

          Mr. Feldman's 1993 Compensation
             
               Mr. Feldman's compensation is determined principally by the
          terms of his employment agreement. As of January 1, 1989, the
          Company entered into an Employment Agreement (the "Agreement") with
          Mr. Feldman which provides that Mr. Feldman will serve as

                                          14
<PAGE>
 
          President and Chief Executive Officer of the Company for the period
          through December 31, 1994. See "Employment Contracts and Termination
          of Employment and Change in Control Arrangements." The Agreement was
          approved by a vote of the entire Board. The Agreement provides Mr.
          Feldman with annual compensation (a minimum base salary) of $300,000
          (subject to review by the Board of Directors). Mr. Feldman also
          received a cash bonus of $120,000 in 1993. Among the factors the
          Board considered in awarding Mr. Feldman a cash bonus, were Mr.
          Feldman's significant contribution to the Company's reduction of its
          long-term debt and improvement of the financial performance of
          certain operating units of the Company. In addition, in 1993 Mr.
          Feldman received compensation of $16,250 for serving as a Director
          and Chairman of the Executive Committee of General Physics
          Corporation, a public company, in which National Patent has an
          approximately 28% investment.

          Compensation Committee Interlocks and Insider Participation

               During the year ended December 31, 1993 the Company did not
          have a Compensation Committee and the entire Board of Directors made
          decisions on compensation of the Company's executives. Mr. Feldman,
          the Company's Chief Executive Officer and a director, Mr. Pollak,
          the Company's Executive Vice President and Treasurer and a director
          and Mr. Greenberg, the Company's Vice President and Chief Financial
          Officer and a director participated in Board executive compensation
          deliberations.

          Employment Contracts and Termination of Employment and Change in
          Control Arrangements

          Agreements with Messrs. Feldman and Pollak. As of January 1, 1989,
          the Company entered into the Agreements with its President and Chief
          Executive Officer, Jerome I. Feldman, and with its Executive Vice
          President and Treasurer, Martin M. Pollak (the "Employees").

               Pursuant to the Agreements, Mr. Feldman will serve as President
          and Chief Executive Officer of the Company and Mr. Pollak will serve
          as Executive Vice President and Treasurer of the Company for the
          period through December 31, 1994. The Agreements provide for each
          Employee to receive annual compensation (a minimum base salary) of
          $300,000 (subject to

                                          15
<PAGE>
 
          increase by the Board of Directors). The Agreements provide for the
          termination of employment upon the Employee's death, physical or
          mental disability or retirement. In addition, the Company may
          terminate the Employee's employment "for cause" (including a failure
          to perform required duties or the engaging in of gross misconduct)
          and each Employee may voluntarily terminate his employment for "Good
          Reason", which occurs if the Employee determines in good faith that
          due to a change in control of the Company he is not able to
          effectively discharge his duties. "Change in control" is defined to
          include (1) any "person" (other than the Employees or certain
          persons who may acquire securities of the Company from an Employee)
          acquiring the beneficial ownership of more than 30% of the Company's
          outstanding securities or (2) certain changes in the composition of
          the Board of Directors of the Company.

               Upon termination by the Company "for cause", all obligations of
          the Company under the Employee's Agreement terminates. Upon
          termination by the Company other than "for cause", disability, or
          retirement, or by the Employee for "Good Reason", such Employee is
          entitled to receive as severance pay an amount equal to his full
          base salary (which at the present time is a minimum of $300,000 for
          each of the Employees) at the rate then in effect, multiplied by the
          greater of (1) the number of years (including fractions thereof)
          remaining in the term of the employment, or (2) the number three. In
          addition, the Employee would receive an amount in cash equal to the
          aggregate spread between the exercise prices of all options held by
          the Employee under the Company's 1973 Non-Qualified Stock Option
          Plan and the higher of (x) the market value of the Common Stock, and
          (y) the highest price paid in connection with any change in control
          of the Company. Subject to certain conditions, the Company would
          also maintain for two years (or until the Employee's commencement of
          full-time employment with a new employer) certain insurance, health
          and disability plans in effect, or arrange for substantially similar
          benefits. The Agreements also contain non-competition and
          confidentiality provisions.

               PROPOSED AMENDMENTS TO THE CERTIFICATE OF INCORPORATION


          Increase in Authorized Shares

               The Board of Directors unanimously recommends that the
          stockholders adopt an amendment to the Company's Certificate of
          Incorporation which will increase the authorized shares of Common
          Stock, par value $.01 per share, from 30,000,000 shares to
          40,000,000 shares. On March 1, 1994, 20,295,388 of the 30,000,000
          shares of Common Stock presently authorized were outstanding and an
          aggregate of 9,710,257 shares were reserved for issuance.

               The Company's Board of Directors has unanimously recommended
          for approval by stockholders the proposal to amend the first
          sentence of Article Fourth of the Certificate of Incorporation as
          follows:

                    "FOURTH: The total number of shares of all classes of
               stock which the Corporation shall have authority to issue is
               fifty-two million eight hundred thousand (52,800,000) shares of
               which forty million (40,000,000) are to be Common Stock of the
               par value of one cent ($.01) per share (hereinafter called the
               "Common Stock"); of which two million eight hundred thousand
               (2,800,000) shares are to be Class B Capital Stock with a par
               value of one cent ($.01) per share (hereinafter called the
               "Class B Capital Stock"); and of which ten million (10,000,000)
               shares are to be Preferred Stock with a par value of one cent
               ($.01) per share (hereinafter called the "Preferred Stock"), to
               be issued in such series and with such terms and conditions as
               the Board of Directors may determine.

               The Board of Directors believes that it would be in the best
          interests of the Company to have additional shares of Common Stock
          available for issuance at its discretion and without the necessity
          for a special stockholders' meeting to enhance the

                                          17
<PAGE>
 
          Company's flexibility in connection with possible future actions,
          such as acquisitions, financings, investment opportunites, internal
          development, retirement of outstanding indebtedness, and other
          corporate purposes.
             
               If the amendment is approved by the stockholders as described
          below, the additional shares may be issued from time to time upon
          authorization of the Board of Directors without further
          authorization of the stockholders for such consideration as the
          Board of Directors may determine and as may be permitted by the laws
          of Delaware. The amendment is not being proposed as a means of
          preventing a change in control or takeover of the Company. However,
          the use of these shares for such a purpose is possible. For
          instance, shares of authorized but unissued or unreserved Common
          Stock could be issued in an effort to dilute the stock ownership and
          voting power of persons seeking to obtain control of the Company or
          could be issued to purchasers who would support the Board of
          Directors in opposing a takeover proposal. Such possibilities may
          have the effect of discouraging a challenge for control or making it
          less likely that such a challenge would take place. The unissued and
          unreserved shares of Common stock, Class B Capital Stock and
          Preferred Stock will still be available for issuance for any proper
          corporate purpose, as authorized from time to time by the Board of
          Directors without further approval by the stockholders of the
          Company. The additional shares of Common Stock will be identical to
          the currently authorized shares of Common Stock in all respects.
          Holders of such shares will not have preemptive rights to purchase
          any capital stock of the Company.
              
          Reasons for and Effect of Authorization
             
               The Board of Directors believes that the complexity of modern
          business financing requires greater flexibility in the Company's
          capital structure than now exists. For example, the Company has in
          the past issued Common Stock as consideration for the retirement of
          outstanding Swiss indebtedness and accrued and unpaid interest
          thereon, in order to strengthen the financial position of the
          Company. The Company may make similar offers in the future, on terms
          and conditions approved by the Board of Directors. If the amendment
          is approved by the stockholders, the Company expects that such
          transaction will in most cases not be subject to further approval of
          stockholders. The additional shares of Stock to be authorized by the
          proposed amendment would be available for issuance from time to time
          for any proper corporate purpose, including, as appropriate,
          acquisitions and public or private sales for cash as a means of
          obtaining capital for use in the Company's business, retirement of
          outstanding indebtedness, and other corporate purposes.
              
               It is not possible to state the actual effect of the
          authorization of the additional shares of stock upon the rights

                                          18
<PAGE>
 
          of holders of the Common Stock, however the effect of the additional
          shares of Common Stock might include dilution of the equity interest
          of the Common Stock.

                APPROVAL OF SELECTION OF KPMG PEAT MARWICK AS AUDITORS

               The Board of Directors has selected KPMG Peat Marwick to audit
          the accounts of the Company for the year ending December 31, 1994.
          KPMG Peat Marwick has no financial interest in the Company and
          neither it nor any member or employee of the firm has had any
          connection with the Company in the capacity of promoter,
          underwriter, voting trustee, director, officer or employee. KPMG
          Peat Marwick has audited the accounts of the Company since 1970. The
          Delaware General Corporation Law does not require the approval of
          the selection of auditors by the Company's stockholders, but in view
          of the importance of the financial statements to the stockholders,
          the Board of Directors deems it desirable that they pass upon its
          selection of auditors. In the event the stockholders disapprove the
          selection, the Board of Directors will consider the selection of
          other auditors. The Board of Directors recommends that you vote in
          favor of the above proposal in view of the familiarity of KPMG Peat
          Marwick with the Company's financial and other affairs acquired
          during its previous service as auditors for the Company.

               A representative of KPMG Peat Marwick is expected to be present
          at the Annual Meeting, with the opportunity to make a statement if
          he desires to do so, and is expected to be available to respond to
          appropriate questions.

                                STOCKHOLDER PROPOSALS

               Stockholders may present proposals for inclusion in the
          Company's 1995 proxy statement provided they are received by the
          Company no later than January 13, 1995, and are otherwise in
          compliance with applicable Securities and Exchange Commission
          regulations.
                                       GENERAL

               So far as is now known, there is no business other than that
          described above to be presented for action by the stockholders at
          the meeting, but it is intended that the proxies will be voted upon
          any other matters and proposals that may legally come before the
          meeting and any adjournments thereof in accordance with the
          discretion of the persons named therein.

                                 COST OF SOLICITATION

               The cost of solicitation of proxies will be borne by the
          Company. It is expected that the solicitations will be made
          primarily by mail, but regular employees or representatives of

                                          19

          the Company may also solicit proxies by telephone or telegraph and
          in person, and arrange for brokerage houses and other custodians,
          nominees and fiduciaries to send proxy material to their principals
          at the expense of the Company.

MONDAY, JULY 11, 1994 (THE "EXPIRATION DATE"), UNLESS THE OFFER IS EXTENDED.

<PAGE>
 
     National Patent Development Corporation (the "Company"), New York, New
York, hereby offers (the "Offer"), upon the terms and subject to the
conditions set forth in this Offering Circular (the "Offering Circular") and
in the accompanying Letter of Instructions (the "Letter of Instructions"), to
exchange (i) common stock, par value $.01 per share (the "Common Stock"), of
the Company with a market value of SFr. 1,000, for each SFr. 1,000 in
principal amount of the Old Swiss Franc Bonds validly tendered and not
withdrawn prior to the Expiration Date and (ii) Common Stock with a market
value of US $1,000 for each US $1,000 in principal amount of Old U.S. Dollar
Bonds validly tendered and not withdrawn prior to the Expiration Date. In
accordance with United States securities laws, the Company is making a
concurrent separate offer on the same terms and for the same consideration as
the Offer to U.S. holders of the Bonds (the "United States Offer").

     On April 30, 1994, there were outstanding SFr. 8,635,000 of the 6%
Convertible Bonds due 1995, SFr. 3,520,000 of the 5 3/4% Convertible Bonds due
1995, SFr. 4,735,000 of the 5 5/8% Convertible Bonds due 1996, SFr. 7,401,000
of the 8% Bonds due 1995 and US $3,926,000 of the 7% Dual Currency Convertible
Bonds due 1996. Interest accrued on the Bonds up to July 22, 1994, or, if the
Company shall have extended the Expiration Date, the tenth (10th) business day
after such adjusted Expiration Date (the "Payment Date"), will be paid in
shares of Common Stock of the Company for each SFr. 1,000 principal amount of
each respective class of Old Swiss Franc Bonds (such amounts referred to
collectively as "Swiss Bond Accrued Interest") and for each US $1,000
principal amount of the Old U.S. Dollar Bonds (such amount referred to as
"U.S. Bond Accrued Interest," and together with the Swiss Bond Accrued
Interest, the "Accrued Interest").

     In the event that Bonds in excess of 60% of the aggregate principal
amount of the outstanding Bonds have been properly tendered by the holders
thereof prior to the Expiration Date and not withdrawn pursuant to the Offer
and the United States Offer, the Company may, upon the terms and subject to
the conditions of the Offer, either (i) accept Bonds tendered on a pro rata
basis according to the aggregate principal amount of all Bonds properly
tendered by the holders thereof prior to the Expiration Date and not withdrawn
pursuant to the Offer and the United States Offer or (ii) amend the terms of
the Offer by notice to the holders of the Bonds, in which case the Offer shall
remain open for an additional ten (10) business days from the date that such
notice is first given. If not more than 60% in aggregate principal amount of
the outstanding Bonds are properly tendered by the Expiration Date and not
withdrawn pursuant to the Offer and the United States Offer, all Bonds so
tendered and not withdrawn will, upon the terms and subject to the conditions
of the Offer and the United States Offer, be exchanged. The Company has the
right, in its sole discretion, to waive any such conditions.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MAKING
OF THE OFFER. HOWEVER, NEITHER THE COMPANY NOR ITS BOARD OF DIRECTORS IS
MAKING ANY RECOMMENDATION TO ANY HOLDER OF BONDS TO TENDER BONDS PURSUANT TO
THE OFFER. EACH HOLDER OF BONDS SHOULD MAKE ITS OWN DECISION WHETHER TO TENDER
ITS BONDS AFTER READING THIS OFFERING CIRCULAR.

              The date of this Offering Circular is June 10, 1994
<PAGE>
 
     The Common Stock to be issued pursuant to the Offer has not been
registered under the United States Securities Act of 1933, as amended (the
"Securities Act"), and may not be offered, sold or delivered, directly or
indirectly, in the United States or to, or for the account of, any U.S. person
except in transactions exempt from the registration requirements of the
Securities Act. In recognition of the fact that exchanging holders of Bonds
("Holders"), even though holding shares of Common Stock for investment, may
wish to be legally permitted to sell such stock when they deem appropriate,
the Company has agreed to prepare and file with the Securities and Exchange
Commission (the "Commission") a registration statement with respect to the
resale of the Common Stock from time to time on the American Stock Exchange,
Inc. or Pacific Stock Exchange, Inc., in privately-negotiated transactions or
otherwise. The Company has agreed to use its best efforts to cause such
registration statement to become effective on or before August 1, 1994. If
such registration statement is not declared effective by the Commission by
August 15, 1994, each exchanging holder will have the option to withdraw the
Bonds tendered by it and to renounce its rights to the Common Stock received
for its account in exchange for such Bonds. Notice of such withdrawal must be
given to the appropriate Exchange Agent prior to August 30, 1994. In any
event, Holders will be required to agree not to sell Common Stock received by
them in the Offer until the earlier of (a) the date which is 40 days after the
payment date for Bonds accepted for payment by the Exchange Agents pursuant to
the Offer (the "Payment Date") and (b) the date on which the registration
statement covering such stock is declared effective by the Commission. Offers
and sales of Common Stock in the United States or to U.S. persons would
constitute a violation of United States law unless made in compliance with the
registration requirements of the Securities Act or pursuant to an exemption
therefrom.

     Tenders of Bonds pursuant to the Offer may be made only to the specified
offices of the Exchange Agents outside the United States. The Company will
deliver Common Stock to the Exchange Agents outside the United States, and the
Exchange Agents will deliver, on behalf of the Company, Common Stock pursuant
to the Offer only to an account or address outside the United States.

     In this Offering Circular, references to "dollars", "$" and "US $" are to
United States dollars, the term "United States" means the United States of
America (including the States and the District of Columbia), its possessions,
its territories and other areas subject to its jurisdiction, and the term
"U.S. person" shall have the meaning set forth in Sections 230.901 through
.904 of Title 17 of the United States Code of Federal Regulations ("Regulation
S").


                             AVAILABLE INFORMATION

     The Company is subject to the informational requirements of the United
States Securities Exchange Act of 1934, as amended (the "Act"), and, in

                                  INTRODUCTION

Description of the Company

     General

     National Patent Development Corporation (the "Company"), incorporated in
Delaware in 1959, is primarily a holding company, which is a legal entity
separate and distinct from its various operating subsidiaries. The Company's
operations consist of four operating business segments: Physical Science,
Distribution, Optical Plastics and Electronics. The Company also has an
investment in two companies in the Health Care industry.

     Physical Science

     The Company's Physical Science Group consists of (i) GPS Technologies,
Inc. ("GPS"), an approximately 92% owned subsidiary, and (ii) GTS Duratek,
Inc. ("Duratek"), an approximately 66% owned subsidiary.

     GPS provides a wide range of management and technical training as well as
specialized engineering services to various commercial industries and the
United States government. Principal clients of GPS include electric utilities,
process industries, manufacturing plants, Federal agencies and the aerospace
industries. In addition, the Company currently owns approximately a 28%
investment in General Physics Corporation ("General Physics"), which provides
a wide range of personnel training and technical support services to the
domestic commercial nuclear power industry and the United States Departments
of Energy and Defense, as well as environmental engineering, training and
support services to governmental and commercial clients.

     On April 7, 1994, General Physics entered into an agreement with GPS and
the Company to acquire substantially all of the operating assets of GPS and
certain of its subsidiaries. General Physics agreed to pay GPS a purchase
price with a current present value of approximately $36 million. The purchase
price will be payable to GPS as follows: $10 million in cash; 3.5 million
shares of General Physics common stock valued at approximately $13,500,000
(based upon the price per share of General Physics common stock prior to the
announcement of the transaction which was $3.875); warrants to acquire
1,000,000 shares of General Physics common stock at $6.00 per share valued at
approximately $1,300,000; warrants to acquire up to 475,644 additional shares
of General Physics common stock at $7.00 per share valued at approximately
$500,000; and 6% Senior Subordinated Debentures due 2004 (the "Debentures"),
in the aggregate principal amount of $15,000,000, valued at approximately
$10,700,000. The values assigned to each component of consideration were based
upon (i) discussions with the independent investment banker to the Independent
Committee of General Physics and the investment banker to GPS and (ii)
negotiations between the Independent Committee of General Physics and the
Board of Directors of GPS. Portions of the cash and stock consideration of the
purchase price will be (a) used to repay outstanding bank debt of GPS which at
March 31, 1994 was $6,350,000 and long-term debt of GPS which at March 31,
1994 was $8,975,000 to be repaid to the Company and (b) held in escrow.

     The transaction is contingent upon the occurrence of certain events,
including, without limitation, the approval of the transaction by the
stockholders of General Physics and GPS. The transaction is anticipated to
close as soon as practicable in the second half of 1994, if all necessary
approvals are obtained and conditions satisfied. The Company anticipates that,
if the aforementioned transaction is consummated, it will own approximately
52% of the outstanding common stock of General Physics, and if the Company
were to exercise all of its warrants, it would own approximately 58% of the
outstanding common stock of General Physics.

     Duratek's operations consist of two operating groups: (1) "Environmental
Services" engaged in cleanup of water and other liquids containing radioactive
and/or hazardous (mixed waste) contaminants and minimum additive vitrification
for long-term stabilization of such waste and (2) "Consulting and Staff
Augmentation" services. Duratek provides services for various utility,
industry, government and commercial clients.

     Distribution

     The Company's Distribution Group, incorporated under the name Five Star
Group, Inc. ("Five Star"), is engaged in the wholesale distribution of home
decorating, hardware and finishing products.

     Healthcare

     The Company's investment in the Health Care industry consists of the
Company's ownership of approximately 36% of the outstanding shares of common
stock of Interferon Sciences, Inc. ("ISI"). ISI is a biopharmaceutical company
engaged in the manufacture and sale of ALFERON N Injection, the only product
approved by the Food and Drug Administration that is based upon a natural
source, multi-species alpha interferon. ISI also is developing its existing
injectable, topical and/or oral formulations of its natural alpha interferon
for the potential treatment of HIV, hepatitis C, hepatitis B, multiple
sclerosis, cancers and other indications.

     Additionally, the Company owns approximately 4.9% of the outstanding
shares of common stock of American White Cross, Inc. (formerly, NPM Healthcare
Products, Inc.) ("White Cross"). White Cross is a leading manufacturer and
marketer of private label adhesive and cotton-based health and personal care
products.

     Optical Plastic

     The Company's Optical Plastics Group, through its wholly owned subsidiary
MXL Industries, Inc., manufactures molded and coated optical products, such as
shields and face masks and non-optical plastic products.

     Electronics

     The Company's Electronics Group, through its subsidiary Eastern
Electronics Mfg. Corporation,  is engaged in contract manufacturing, such as
printed circuit board assembly for the electronics industry.

Recent Developments

     American Drug Company

     On February 2, 1994, the Board of Directors of the Company approved a
dividend of approximately 46.1% of the common stock of American Drug Company
to holders of record of the Company's Common Stock and Class B Capital Stock.
American Drug Company is currently a wholly-owned subsidiary of the Company.
The dividend will be at the rate of one share, plus one warrant to purchase
one share of American Drug Company common stock at an exercise price per share
of $1.00, for every four outstanding shares of Common Stock and Class B
Capital Stock of the Company. The distribution of American Drug Company common
stock to the Company's stockholders will result in direct ownership in a
company focused on developing markets for American-made generic pharmaceutical
and personal care products in Russia and the other states of the Commonwealth
of Independent States and on developing other business opportunities.
Following the distribution, the Company will own 6,000,000 shares of the
common stock of American Drug Company, representing approximately 53.9% of the
outstanding common stock of American Drug Company, without accounting for
outstanding options and warrants.

     Interferon Sciences, Inc.

     On May 13, 1994, ISI filed a registration statement with the Commission
relating to a proposed public offering of 3,000,000 shares of its common stock
(with an additional 450,000 shares of its common stock subject to an over-
allotment option).  D. Blech & Company, Incorporated is the underwriter of the
offering.

     The Company is a Delaware corporation, incorporated in 1959, and its
headquarters are located at 9 West 57th Street, New York, New York 10019. Its
telephone number is (212) 230-9500. The Company's Annual Report on Form 10-K for

*  Does not include any Bonds outstanding that are owned by the Company or its
affiliates.

** All Bonds that have been repurchased and are owned by the Company or its
affiliates (except SFr. 6,582,000 of the 8% Bonds which have been repurchased
and are owned by affiliates of the Company) will be retired upon the completion
of the Offer.

     Repurchases by the Company

     The Company and its affiliates have repurchased in the open market and
hold SFr. 11,532,000 and US $285,000 of the Bonds.  The Company intends to
deliver to the Exchange Agents for cancellation approximately SFr. 4,950,000 and
US $285,000 of Bonds repurchased by it.  The remaining SFr. 6,582,000 of 8%
Bonds are owned by affiliates of the Company as collateral for loans made by
such affiliates to the Company and will not be retired.

     As of March 31, 1994, the Company had an aggregate of $40,469,000 of
long-term indebtedness, including $20,797,000 of the Bonds, of which $11,025,000
is included in current maturities of long-term debt.  For a description of the
outstanding indebtedness of the Company, see "Capitalization."

     The Company is making the Offer to reduce its long-term indebtedness,
to increase its book value and to provide the Company with additional financial
flexibility in its operations.  See "Purpose of the Offer" and "Capitalization."
In accordance with United States securities laws, the Company is making a
concurrent separate offer on the same terms and for the same consideration as
the Offer to U.S. holders of the Bonds (the "United States Offer").  The Company
will accept for exchange in the Offer and the United States Offer Bonds
representing up to 60% of the aggregate principal amount outstanding of the
Bonds.  As of April 30, 1994, 60% of the aggregate principal amount outstanding
of the Bonds was equal to SFr. 17,900,000, assuming an exchange rate of 1.4115
with respect to the Old U.S. Dollar Bonds.

Summary Terms and Conditions of the Offer

     Exchange Consideration

     In exchange for each SFr. 1,000 principal amount and each US$ 1,000
principal amount of any of the Bonds validly tendered, the Company offers shares
of its common stock with a par value of US$ 0.01  per share (the "Common Stock")
and with a market value of SFr. 1,000 with respect to Old Swiss Francs Bonds and
of US$ 1,000 with respect to Old U.S. Dollar Bonds.  Interest accrued on the
Bonds up to the Payment Date (as defined

                                     -3-
<PAGE>
 
below) will also be paid in Common Stock.  Fractional shares of Common Stock
resulting from such exchange will be rounded up to the nearest integral
multiple.

     The exchange rate between US$ and Swiss Francs will be determined by
the Exchange Agents on the basis of the Swiss Franc/US$ spot rate reported in
the Wall Street Journal Europe Edition on the fifth trading day prior to July
11, 1994.

     The market value of the Common Stock offered in exchange for the Bonds
will be determined on the basis of the average of the last sale prices on the
American Stock Exchange, Inc. of the Common Stock for the ten (10) trading days
ending five (5) trading days prior to July 11, 1994.

     Offering Period

     The offer to tender the Bonds for exchange is open from June 10, 1994
to July 11, 1994.  The Company reserves the right to extend the Offer for an
additional ten (10) business days, until July 25, 1994.  The date on which the
offer, or any extension thereof, expires is hereinafter referred to as the
"Expiration Date."

     Payment Date

     Subject to the conditions set forth in Section 13, the "Payment Date"
is July 25, 1994, or, if the Expiration Date has been extended beyond July 11,
1994, the tenth (10th) business day after the Expiration Date.

     Maximum Acceptance

     Subject to the condition set forth in Section 14, the Company will
accept for exchange Bonds representing up to 60% of the aggregate principal
amount of the outstanding Bonds (the percentage limitation being calculated on
the overall principal amount of all outstanding Bonds, i.e. irrespective of the
individual series of Bonds).  The Company reserves the right to exchange Bonds
representing up to 62% of the aggregate principal amount of the outstanding
Bonds pursuant to the Offer and the United States Offer.  In the event Bonds in
excess of 60% of the aggregate principal amount are tendered, the Company may
either (i) accept Bonds tendered on a pro rata basis according to the aggregate
principal amount of all Bonds properly tendered by the Expiration Date or (ii)
amend the terms of the Offer by notice to the holders of the Bonds, in which
case the Offer shall remain open for an additional ten (10) business days from
the date that such notice is first given.  The Company reserves the right to
waive the maximum acceptance restriction.  In no event will the offer be
extended beyond July 25, 1994.

     Registration of Common Stock

     The Company shall apply for registration of the newly issued shares of
Common Stock with the United States Securities and Exchange Commission (the
"Commission").  Exchanging holders of Bonds may not sell the Common Stock
received in the Offer within the United States or to a U.S. person until forty
(40) days after the Payment Date or the date on which the registration statement
is declared effective by the Commission, whichever is earlier.

     Conditions of Offer

     The Offer is subject to certain conditions as more fully described in this
Offering Circular.

     Withdrawal Rights

     Bonds tendered pursuant to the Offer may be withdrawn by holders of
Bonds at any time prior to the Expiration Date.  After the Expiration Date,
Bonds may be withdrawn if the registration statement of the Company with respect
to the Common Stock has not been declared effective by the Commission on or
prior to August 15, 1994.

The Offer

     1.  Terms of the Offer. Upon the terms and subject to the conditions of
the Offer, the Company will accept for exchange Bonds representing up to 60%
of the aggregate principal amount of the outstanding Bonds which are validly
tendered pursuant to the Offer and the United States Offer on or prior to the
Expiration Date and not theretofore withdrawn as permitted by Section 9 of the
Offer. The term "Expiration Date" means 12:00 Noon, Geneva time, on July 11,
1994, unless the Company, in its sole discretion, shall have extended the
period of time for which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date, not beyond 12:00 Noon,
Geneva time, on July 25, 1994, at which time the Offer, as so extended by the
Company, shall expire. The payment date (the "Payment Date") for Bonds
accepted for payment by the Exchange Agents pursuant to the Offer will be July
25, 1994. However, if the Company shall have extended the period of time for
which the Offer is open, the Payment Date shall be the tenth (10th) business
day after the adjusted Expiration Date.

     The consideration offered by the Company in exchange for each SFr. 1,000
principal amount of any and all Old Swiss Franc Bonds and each US $1,000
principal amount of any and all Old U.S. Dollar Bonds validly tendered and not
withdrawn prior to the Expiration Date is Common Stock with a market value of
SFr. 1,000, with respect to the Old Swiss Franc Bonds, and of US $1,000, with
respect to the Old U.S. Dollar Bonds. Interest accrued on the Bonds up to the
Payment Date will be paid in shares of Common Stock of the Company for each
SFr. 1,000 principal amount of Old Swiss Franc Bonds (such amounts referred to
collectively as "Swiss Bond Accrued Interest") and for each US $1,000
principal amount of the Old U.S. Dollar Bonds (such amount referred to as
"U.S. Bond Accrued Interest," and together with the Swiss Bond Accrued
Interest, the "Accrued Interest"). Fractional shares of Common Stock resulting
from such exchange will be rounded up to the nearest integral multiple.

     The Company currently intends to exchange Bonds representing 60% of the
aggregate principal amount of the outstanding Bonds, irrespective of the
individual series of the Bonds, pursuant to the Offer and the United States
Offer. The Company reserves the right to exchange Bonds representing up to 62%
of the aggregate principal amount of the outstanding Bonds pursuant to the
Offer and the United States Offer. In the event that Bonds in excess of 60% of
the aggregate principal amount of the outstanding Bonds have been properly
tendered by the holders thereof prior to the Expiration Date and not
withdrawn, the Company may, upon the terms and subject to the conditions of
the Offer, either (i) accept Bonds tendered on a pro rata basis to the holders
according to the aggregate principal amount of all Bonds properly tendered by
the Expiration Date and not withdrawn or (ii) amend the terms of the Offer by
notice to the holders of the Bonds, in which case the Offer shall remain open
for an additional ten (10) business days from the date that such notice is
first given. If not more than 60% in aggregate principal amount of the
outstanding Bonds are properly tendered by the Expiration Date and not
withdrawn, all Bonds so tendered and not withdrawn will, upon the terms and
subject to the conditions of the Offer, be exchanged. The Company has the
right, in its sole discretion, to waive any such conditions.

                                     -5-
<PAGE>
 
     For each SFr. 1,000 principal amount of Old Swiss Franc Bonds exchanged,
the holder will receive Common Stock with a value equal to the sum of SFr.
1,000 and the respective amount of Swiss Bond Accrued Interest for the
tendered Old Swiss Franc Bond (the "Swiss Bond Common Stock Value"). For each
US $1,000 principal amount of Old U.S. Dollar Bonds exchanged, the holder will
receive Common Stock with a value equal to the sum of US $1,000 and the U.S.
Bond Accrued Interest (the "U.S. Bond Common Stock Value"). The number of
shares of Common Stock issued for each SFr. 1,000 principal amount of Old
Swiss Franc Bonds exchanged will be equal to the amount obtained by dividing
(i) the Swiss Bond Common Stock Value by (ii) the Swiss Franc/U.S. Dollar spot
rate reported in The Wall Street Journal-Europe Edition on the fifth trading
day prior to July 11, 1994 (as determined by the Exchange Agents), and then
dividing the resulting quotient by the average of the last sale prices on the
American Stock Exchange ("AMEX") of the Common Stock for the ten trading days
ending five trading days prior to July 11, 1994. The number of shares of
Common Stock issued for each US $1,000 principal amount of Old U.S. Dollar
Bonds exchanged will be equal to the number obtained by dividing (i) the U.S.
Bond Common Stock Value by (ii) the average of the last sale prices on the
AMEX of the Common Stock for the ten trading days ending five trading days
prior to July 11, 1994. Fractional shares of Common Stock resulting from such
exchange will be rounded up to the nearest integral multiple.

     In recognition of the fact that holders of Common Stock, even though
holding Common Stock for investment, may wish to be legally permitted to sell
their shares of Common Stock when they deem appropriate, the Company has
agreed to prepare and file with the Commission a registration statement with
respect to the resale of the shares of Common Stock from time to time on the
AMEX, on the Pacific Stock Exchange, Inc., in privately-negotiated
transactions or otherwise. In any event, the holders of Common Stock may not
be able to sell shares of Common Stock until the registration statement has
been declared effective by the United States Securities and Exchange
Commission (the "Commission"). Exchanging holders of Bonds may not sell the
Common Stock received in the Offer within the United States or to, or for the
account or benefit of, U.S. persons, until the earlier of (a) the date which
is 40 days after the Payment Date and (b) the date on which the registration
statement covering the Common Stock is declared effective by the Commission.
In the event that the registration statement covering the Common Stock is not
declared effective by the Commission prior to the Payment Date, the Common
Stock issued pursuant to the Offer will be represented by temporary global
stock certificates until the earlier of the dates referred to in the
immediately preceding sentence.

     The Company will use its best efforts to cause the registration statement
to become effective on or before August 1, 1994. There can, however, be no
assurance that the registration statement will have become effective on such
date. If such registration statement is not declared effective by the
Commission on or before August 15, 1994, each exchanging holder will have the
option to withdraw the Bonds tendered by it and to renounce its rights to the
Common Stock received for its account in exchange for such Bonds. Notice of
such withdrawal must be given to the appropriate Exchange Agent prior to
August 30, 1994.

     If the Company shall decide, in its sole discretion, to increase the
consideration offered in the Offer or the percentage of Bonds sought in the
Offer beyond 62% and, at the time that notice of such increase is first
published in the manner specified below, the Offer is scheduled to expire
earlier than the tenth (10th) United States business day from, and including,
the date that such notice is first so published in the manner specified below,
then the Offer will be extended until the expiration of such period of ten
(10) United States business days. For purposes of the Offer, a "United States
business day" means any day other than a Saturday, Sunday or United States
federal holiday and consists of the time period from 12:01 A.M. through 12:00
midnight, New York City time.

     The Company expressly reserves the right (i) to terminate the Offer and
not accept for exchange any Bonds, upon the occurrence of the event specified
in Section 14, by giving notice in writing or by telex of such termination to
the Exchange Agents, and (ii) to amend the Offer at any time, or from time to
time, in any respect other than to decrease the consideration offered for the
Bonds in the Offer.

                                     -6-
<PAGE>
 
     Any extension or amendment of the Offer will be followed as promptly as
practicable by public announcement thereof, such announcement in the case of
an amendment or extension to be issued no later than 9:00 a.m., New York City
time (3:00 p.m., Geneva time), within two United States business days after
the previously scheduled Expiration Date. Without limiting the manner in which
the Company may choose to make any public announcement, the Company will have
no obligation to publish, advertise or otherwise communicate any such public
announcement, other than by delivering a written copy thereof to the Exchange
Agents, which will act as the Company's agents in issuing the announcement to
the Feuille Officielle Suisse du Commerce and to a daily newspaper in the
cities of Basle, Geneva and Zurich within two United States business days
after the previously scheduled Expiration Date. The Company may terminate the
Offer, in its sole discretion, at any time after the Expiration Date and prior
to the Payment Date, pursuant to Section 13.

     This Offering Circular will be provided to all principal offices of the
Exchange Agents in Switzerland. The Offering Circular will not be provided to
any person in the U.S. or to any U.S. person. A separate offering circular
will be circulated to U.S. holders of the Bonds in connection with the United
States Offer.

     2.  Purpose of the Offer. The purpose of the Offer is to reduce the
Company's long-term indebtedness and annual interest expense, to increase the
Company's book value and to provide the Company with additional financial
flexibility in its operations. In addition, the issuance of the Common Stock
in the Offer will enable the Company to lower its ratio of long-term debt to
total capitalization.

     Assuming that 60% of the Bonds had been exchanged on March 31, 1994, the
Company would have reduced its consolidated long-term debt, less current
maturities, from approximately $25,778,000 to approximately $19,914,000 and
increased its book value from approximately $66,158,000 to approximately
$79,292,000.

     3.  Investment Considerations.

     (a) Liquidity; Financial Condition. The Company believes that it has
sufficient cash and cash equivalents and borrowing availability under existing
and potential lines of credit to satisfy its cash requirements until the first
scheduled maturity of its Swiss Franc denominated indebtedness on March 1,
1995. However, in order for the Company to meet its long-term cash needs,
which include the repayment of $13,518,000 of Swiss Franc denominated
indebtedness scheduled to mature in 1995 and $7,279,000 of Swiss Franc
denominated indebtedness which is scheduled to mature in 1996, the Company
must obtain additional funds. The Company has reduced and is continuing to
reduce its long-term debt through the issuance of equity securities in
exchange for long-term debt (including the shares of the Company's Common
Stock issued in the Offer), and is also exploring new credit arrangements on
an ongoing basis. However, there is no assurance that the Company will be able
to obtain any new credit arrangements.

     At March 31, 1994, the Company and its majority-owned subsidiaries held
cash and cash equivalents totaling $9,848,000. Of these amounts, approximately
$7,748,000 is held by the Company and is available for the general corporate
purposes of the Company.

     (b)  Recent Historical Operating Losses, Retained Earnings Deficit. Since
1987, the Company has experienced losses before income taxes, discontinued
operations and extraordinary items. These losses were the result of operating
losses at certain of its subsidiaries, which were not wholly offset by
operating profits from certain of its other subsidiaries. The Company's
current strategy is to consolidate certain related operating businesses and to
improve their operating results, while continuing to make investments in new
ventures or make selected divestitures based on market conditions.

     For the quarter ended March 31, 1994, the Company's loss from operations
before income taxes and extraordinary items was $2,394,000, as compared to a
loss of $2,939,000 for the quarter ended March 31, 1993. For the year ended
December 31, 1993, the Company's loss from operations before income taxes and
extraordinary items was $8,371,000, as compared to a loss of $13,178,000 for
the year ended December 31, 1992. As of March

                                     -7-
<PAGE>
 
31, 1994, the Company had stockholders' equity of $66,158,000 and a deficit of
$41,488,000.  Losses in future years may adversely affect the Company's ability
to service its debt.

     (c)  Ratio of Earnings to Fixed Charges. The ratio of earnings to fixed
charges represents the number of times that fixed charges were covered by
income before income taxes, discontinued operations and extraordinary items,
as adjusted by such fixed charges. For the three months ended March 31, 1994
and the year ended December 31, 1993, the Company had a deficiency in the
coverage of fixed charges to earnings before fixed charges of $2,326,000 and
$10,747,000, respectively.

     (d)  Holding Company; Dependence on Subsidiaries. The Company is
primarily a holding company, which is a legal entity separate and distinct
from its various operating subsidiaries. As a holding company, the Company is
dependent upon management fees, dividends and other payments or advances from
operating subsidiaries as its principal source of cash to service outstanding
debt. The ability of the Company to obtain cash from an operating subsidiary
depends upon, among other factors, the operating results of the subsidiary,
restrictions on payments to the Company imposed by creditors of the
subsidiary, restrictions on payments to the Company imposed by other
agreements governing the subsidiary and the degree of dilution of dividend
payments resulting from public ownership of equity securities of the
subsidiary.

     As of March 31, 1994, there is currently at the holding company level
approximately $7,748,000 of cash and cash equivalents. Duratek, under its
Revolving Line of Credit, is prohibited from making any payments to the
Company. GPS, under the terms of its Amended and Restated Revolving Credit and
Term Loan and Security Agreement, may only pay the Company an amount equal to
80% of the amount GPS would have paid in federal income taxes if it filed its
federal income tax return on a stand-alone basis. However, GPS may be
prohibited from distributing approximately $1,200,000 of management fees and
tax sharing payments to the Company in 1994 if GPS were to be in violation of
certain covenants in its bank agreements.

     The rights of the Company and its creditors to participate in the assets
of any of the Company's subsidiaries upon bankruptcy or liquidation of a
subsidiary are subject to the prior claims of the subsidiary's creditors
except to the extent the Company may itself be a creditor with recognized
claims against the subsidiary; however, the Company's claims may be
subordinate to the claims of any secured creditors of the subsidiary. See "The
Company."

     (e)  Currency Fluctuations. On March 31, 1994, the value of the Swiss
Franc to the U.S. dollar was approximately 1.412 to 1. At March 31, 1994, the
Company had an aggregate of SFr. 26,318,000 of Swiss Franc denominated
indebtedness outstanding, of which SFr. 23,823,000 represents principal amount
outstanding and SFr. 2,495,000 represents interest accrued thereon. Foreign
currency valuation fluctuations may adversely affect the results of operations
and financial condition of the Company. In order to protect itself against
foreign currency valuation fluctuations, the Company has at times swapped or
hedged a portion of its obligations denominated in Swiss Francs; however, at
March 31, 1994, the Company had not swapped or hedged any of its Swiss Franc
obligations. If the value of the Swiss Franc to the U.S. dollar increases, the
Company will recognize transaction losses on its Swiss Franc obligations.
There can be no assurance that the Company will be able in the future to swap
or hedge obligations denominated in foreign currencies at prices acceptable to
the Company, or at all. The Company will review its policy as to hedging on a
continuing basis.

     (f)  Ranking of Common Stock; Certain Bankruptcy Law Considerations.
Consummation of the Offer may have significant bankruptcy consequences for
exchanging holders of Bonds. In general, a note, bond or other evidence of
indebtedness represents a potential bankruptcy claim equal to its face amount,
plus accrued and unpaid interest as of the date of the commencement of the
bankruptcy case, less any unamortized original issue discount. The
determination of original issue discount for bankruptcy purposes may not be
the same as that applicable for tax purposes. Equity securities rank below all
debt claims and claims of holders of common stock rank below claims of holders
of preferred stock. Accordingly, exchanging holders will have a bankruptcy
claim that ranks below the claims of all remaining holders of Bonds, as well
as $16,006,000 of other long-term indebtedness less current maturities at
March 31, 1994.

                                     -8-
<PAGE>
 
     4.  Risks to Non-Exchanging Holders. Holders of the Bonds who do not
participate in the Offer may be subject to certain adverse consequences.

     The purchase of Bonds pursuant to the Offer will reduce the aggregate
principal amount of Bonds that might otherwise trade publicly, will reduce the
number of holders of Bonds and could adversely affect the liquidity and market
value of the remaining Bonds held by the public. A debt security with a
smaller float may command a lower price than a comparable debt security with a
greater float. Therefore, the market price for an Old Bond may be adversely
affected to the extent that the principal amount of the Bonds tendered
pursuant to the Offer reduces the float of the Bonds. This reduced float may
also tend to make the trading price more volatile.

     5.  Price Range of the Bonds. The Bonds are traded in Switzerland on the
Stock Exchanges of Zurich, Basle and Geneva. The following table sets forth
the range of high and low sale prices of each of the classes of Bonds in
percentages of principal amount as reported by the Zurich Stock Exchange for
the periods set forth below:

     7.  Acceptance for Exchange and Payment. Upon the terms and subject to
the condition to acceptance for exchange set forth in Section 14 and the other
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the Company will
accept for exchange up to 60% of the aggregate principal amount outstanding of
the Bonds validly tendered on or prior to the Expiration Date and not properly
withdrawn as permitted by Section 9. In the event that Bonds in excess of 60%
of the aggregate principal amount of the outstanding Bonds have been properly
tendered by the Expiration Date and not withdrawn, the Company may, upon the
terms and subject to the conditions of the Offer, either (i) accept Bonds
tendered on a pro rata basis according to the aggregate principal amount of
all Bonds properly tendered by the Expiration Date and not withdrawn or (ii)
amend the terms of the Offer by notice to holders of the Bonds, in which case
the Offer shall remain open for an additional ten (10) business days from the
date that such notice is first given. If not more than 60% in aggregate
principal amount of the Bonds are properly tendered by the Expiration Date and
not withdrawn, all Bonds so tendered and not withdrawn will, upon the terms
and subject to the conditions of the Offer, be exchanged.

     Subject to the conditions set forth in Section 13, the Payment Date for
Bonds accepted for payment by the appropriate Exchange Agent will be July 25,
1994, provided, however, if the Company shall have extended the period of time
for which the Offer is open, the Payment Date shall be the tenth (10th)
business day after the Expiration Date of the Offer. The term "Expiration
Date" means 12:00 Noon, Geneva time, on July 11, 1994, unless the Company in
its sole discretion shall have extended the period of time for which the Offer
is open, in which event the term "Expiration Date" shall mean the latest time
and date, not beyond 12:00 Noon, Geneva time on July 25, 1994 at which time
the Offer, as so extended by the Company, shall expire. In all cases, payment
for Bonds exchanged pursuant to the Offer will be made only upon timely
receipt by the appropriate Exchange Agent at its specified office in
Switzerland of such Bonds, together with any and all unmatured and matured but
unpaid coupons. In the event that unmatured and matured but unpaid coupons are
not submitted with Bonds tendered, such Bonds will not be accepted for tender.
The respective amount of Swiss Bond Accrued Interest will be paid on the Old
Swiss Franc Bonds and the U.S. Bond Accrued Interest will be paid on the Old
U.S. Dollar Bonds, all to be paid in the Company's Common Stock. Tenders of
Old Swiss Franc Bonds will be accepted only in principal amounts of SFr. 1,000
and integral multiples thereof and tenders of Old U.S. Dollar Bonds will be
accepted only in principal amounts of US $1,000 and integral multiples
thereof. If fractional Bonds result from proration, such fractions shall be
rounded up to the nearest integral multiple of SFr. 1,000 or US $1,000, as the
case may be.

  For purposes of the Offer, the Company shall be deemed to have accepted for
exchange tendered Bonds on the Expiration Date, provided that the condition to
the Offer set forth in Section 14 has been waived or satisfied, unless it gives
notice to the contrary in writing or by telex to the appropriate Exchange
Agents.  The Company will give notice and the Exchange Agents shall publish such
notice in the Feuille Officielle Suisse du Commerce and a daily newspaper in the
cities of Basle, Geneva and Zurich no later than five (5) business days after
the Expiration Date.  Payment for Bonds so accepted for exchange will be made on
the Payment Date, unless the conditions set forth in Section 13 have not been
waived or satisfied, by delivery of the stock certificates representing the
Common Stock to the Exchange Agents at their specified offices in Switzerland.

     If any tendered Bonds are not exchanged for any reason, the Exchange
Agents will return the Bonds tendered to the holder thereof without expense to
the tendering bondholder as promptly as practicable after the expiration or
termination of the Offer.

     8.  Procedures for Tendering Bonds. In order to exchange Bonds validly
pursuant to the Offer, a Letter of Instructions for acceptance of the Offer
must be submitted by or on behalf of each beneficial owner of Bonds to one of
the Exchange Agents in Switzerland. Any financial institution holding Bonds on
behalf of one or more beneficial owners may submit one Letter of Instructions
for all such beneficial owners. Bonds held directly by a beneficial owner must
be tendered, through a bank in Switzerland, to an Exchange Agent accompanied
by a Letter of Instructions signed by such beneficial owner. Tenders on behalf
of bondholders will be valid only if made through banks in Switzerland and
received by Banque Scandinave en Suisse, with respect to the 8% Bonds, or Bank
Leu AG, with respect to all of the Bonds except the 8% Bonds, prior to the
Expiration Date.

                                    -16-
<PAGE>
 
     Except as set forth below, all questions as to the validity, form and
eligibility (including time of receipt) of any tendered Bonds pursuant to any
of the procedures described above will be determined in the sole discretion of
the appropriate Exchange Agent, whose decision will be final and binding. The
Company reserves the absolute right to reject any or all tenders of any Bonds
determined by it, after consultation with the appropriate Exchange Agent, not
to be in proper form or if the acceptance of or payment for such Bonds may, in
the opinion of the Company's counsel, be unlawful or result in adverse tax
consequences to the Company. The Company also reserves the absolute right to
waive any of the conditions of the Offer or, after consultation with the
appropriate Exchange Agent, any defect or irregularity in any tender with
respect to Bonds of any particular bondholder and the Company's interpretation
of the terms and conditions of the Offer will be final and binding. None of
the Company, the Exchange Agents or any other person will be under any duty to
give notification of any defect or irregularity in tender and none shall incur
any liability for failure to give any such notification.

     9.  Withdrawal Rights. Except as stated in this Section 9, tenders of
Bonds made pursuant to the Offer are irrevocable. Bonds tendered pursuant to
the Offer may be withdrawn at any time prior to the Expiration Date.

     For a withdrawal to be effective, a written, telegraphic, telex or
facsimile transmission notice of withdrawal must be timely sent or delivered
by or on behalf of the bondholder to the appropriate Exchange Agent and
received by such Exchange Agent prior to the Expiration Date. Any such notice
of withdrawal must specify the name of the bank having tendered on behalf of
the bondholder, the Bonds to be withdrawn and the aggregate principal amount
of Bonds to be withdrawn. Withdrawals may only be made in principal amounts of
SFr. 1,000 or integral multiples thereof in the case of the Old Swiss Franc
Bonds or US $1,000 or integral multiples thereof in the case of the Old U.S.
Dollar Bonds. Bonds tendered pursuant to the Offer may also be withdrawn after
the Expiration Date if the registration statement of the Company with respect
to the Common Stock has not been declared effective by the Commission on or
prior to August 15, 1994.

     All questions as to validity (including time of receipt) of notices of
withdrawal will be determined by the appropriate Exchange Agent, in its sole
discretion, which determination will be final and binding. None of the
Company, the Exchange Agents or any other person will be under any duty to
give notification of any defect or irregularity in any notice of withdrawal
and none shall incur any liability for failure to give any such notification.

     Withdrawals of Bonds may not be rescinded, and any Bonds withdrawn will
thereafter be deemed not validly tendered for purposes of the Offer. However,
withdrawn Bonds may be returned at any subsequent time prior to the Expiration
Date by again following the procedures described in Section 8.

     10.  Certain Tax Consequences. The following is a summary of certain
Swiss tax consequences and certain United States federal income tax
consequences arising with respect to the Offer. The summary does not address
any tax consequences that may affect a bondholder in any jurisdiction other
than Switzerland and the United States. Each bondholder is urged to consult
his own tax advisor to understand fully the tax consequences of accepting the
Offer or of not accepting the Offer and continuing to own Bonds.

     Switzerland. The Offer will not give rise to any stamp taxes on the
exchange of securities.

     United States. Under current United States federal income tax law, no
withholding of United States federal income tax will be required on the
payment effected outside the United States to an exchanging holder of Bonds
that is a United States Alien (as defined below) of Common Stock (the
"Exchange Consideration") by the Company or the Exchange Agents provided that
(i) the holder does not actually or constructively own 10 percent or more of
the total combined voting power of all classes of voting stock of the Company
and (ii) the holder is not a controlled foreign corporation that is related to
the Company through stock ownership. The Company has determined and will
certify on and as of the Payment Date that it is not, and at no relevant time
has been, a "United States real property holding corporation" under Section
897(c)(2) of the Internal Revenue Code. Accordingly, an exchanging holder of
Bonds will not be subject to withholding of United States federal income tax
under the United States Foreign Investment in Real Property Tax Act of 1980 on
the receipt of the Exchange Consideration pursuant to the Offer.

     Under current United States federal income tax law, a holder of Common
Stock that is a United States Alien will not be subject to withholding of
United States federal income tax on a sale of such stock effected outside

                                    -17-
<PAGE>
 
the United States, provided that the Company at no time is a United States real
property holding corporation. A holder of Common Stock that is a United States
Alien, upon the distribution of dividends with respect to such stock, ordinarily
will be subject to withholding of United States federal income tax at a rate of
30 percent, unless a lower treaty rate applies. The Company will not pay any
additional amounts in respect of any such withholding tax.

     For purposes of this Offering Circular, the term "United States Alien"
means any person who, for United States federal income tax purposes, (i) is a
foreign corporation, a non-resident alien individual, a non-resident alien
fiduciary of a foreign estate or trust, or a foreign partnership one or more
of the members of which is, for United States federal income tax purposes, a
foreign corporation, a non-resident alien individual or a non-resident alien
fiduciary of a foreign estate or trust and (ii) is not engaged in a trade or
business in the United States (and is not treated as so engaged through a
partnership or otherwise), to which trade or business income in respect of the
Bonds or Common Stock is (or is treated as) effectively connected.

     11.  Exchange Agents. Banque Scandinave en Suisse, acting through its
specified office in Switzerland, will serve as Exchange Agent with respect to
the exchange of the 8% Bonds, and Bank Leu AG, acting through its specified
office in Switzerland, will serve as Exchange Agent with respect to all other
Bonds. BANQUE SCANDINAVE EN SUISSE and BANK LEU AG may be referred to
individually as the "Exchange Agent" or, collectively, as the "Exchange
Agents."

     Each Exchange Agent will receive a fee equal to 3.5% of the aggregate
principal amount of all Bonds tendered for exchange pursuant to this Offer,
and not the United States Offer, plus a bonus if the aggregate amount of Bonds
tendered reaches certain thresholds. In addition, the Exchange Agents will be
reimbursed for their costs and expenses.

     Assuming that 60% of the Bonds are tendered for exchange, total fees and
expenses of the Offer, including legal, accounting, investment, banking
presentation and printing fees, are not expected to exceed approximately SFr.
1,180,000 based on the April 30, 1994 exchange rate of 1.4115.

     Requests for additional information or additional copies of this Offering
Circular should be directed to the Exchange Agents at their specified offices
in Switzerland.

     12.  Description of Common Stock.

     Description of Common Stock.

     As of May 12, 1994 the Company had outstanding two classes of common
stock: 20,310,706 shares of Common Stock, par value $.01 per share, entitled
to one vote per share on all matters, and 250,000 shares of Class B Capital
Stock, par value $.01 per share ("Class B Stock"), entitled to ten votes per
share on all matters, without distinction between classes except when approval
of a majority of each class is required by statute. The Class B Stock is
convertible at any time into shares of Common Stock on a share for share
basis.

     Since the Common Stock and Class B Stock do not have cumulative voting
rights, the holders of shares having more than 50% of the voting power, if
they choose to do so, may elect all the directors of the Company and the
holders of the remaining shares would not be able to elect any directors.

     The holders of Common Stock and Class B Stock are entitled to share

in Delaware in 1959, is primarily a holding company, which is a legal entity
separate and distinct from its various operating subsidiaries. The Company's
operations consist of four operating business segments: Physical Science,
Distribution, Optical Plastics and Electronics. The Company also has an
investment in two companies in the Health Care industry.

         The Company's Physical Science Group consists of (i) GPS Technologies, 
Inc. ("GPS"), an approximately 92% owned subsidiary and (ii) GTS Duratek, Inc. 
("Duratek"), an approximately 66% owned subsidiary.

         GPS provides a wide range of management and technical training as
well as specialized engineering services to various commercial industries and
the United States government. Principal clients of GPS include electric
utilities, process industries, manufacturing plants, Federal agencies, and the

         (c)  Narrative Description of Business

RECENT DEVELOPMENTS

GENERAL PHYSICS CORPORATION AND
GPS TECHNOLOGIES, INC. PROPOSED TRANSACTION
- -------------------------------------------

         On January 13, 1994, General Physics signed a Letter of Intent with 
GPS and the Company to acquire substantially all of the operating assets of
GPS and certain of its subsidiaries. The Company currently owns approximately
92% of the outstanding common stock of GPS and approximately 28% of the
outstanding common stock of General Physics. On March 28, 1994 the Board of
Directors of both GPS and General Physics approved the transaction. The
parties are currently negotiating the terms of a definitive agreement and the
transaction is anticipated to close as soon as practicable in the second half
of 1994, if all necessary approvals are obtained and conditions satisfied.

         The purchase price has a current present value of approximately $36
million based on current market prices.  The purchase price will be payable to
GPS as follows:  $10 million cash; 3.5 million shares of General Physics common
stock valued at approximately $13,500,000 (based upon the price per share of
General Physics common stock prior to the announcement of the transaction which
was $3.875); warrants to acquire 1,000,000 shares of General Physics common
stock at $6.00 per share valued at approximately $1,300,000; warrants to acquire
up to 475,644 additional shares of General Physics common stock at $7 per share
valued at approximately $500,000; a $15 million ten-year senior subordinated
debenture (the "Debentures") valued at approximately $10,700,000, accruing
interest at 6% per annum, interest payable only for the first five years, with
70% of principal payable in equal quarterly installments during the remaining
five years until maturity.  The values assigned to each component of
consideration were based upon discussions with the 

                                      2
<PAGE>
 
independent investment banker to the Independent Committee of General Physics
and the investment banker to GPS. Portions of the cash and stock consideration
of the purchase price will be (a) used to repay outstanding bank debt of
$5,650,000 (as of December 31, 1993) and long-term debt of GPS of $8,809,000
(as of December 31, 1993) to be repaid to the Company. In addition $1.5
million of Debentures are held in escrow for the benefit of General Physics in
connection with certain indemnification obligations.

        The transaction was recommended by an Independent, Committee of General
Physics' Board of Directors and was approved by the Board of Directors of both
General Physics and GPS and is contingent upon the occurrence of certain
events, including, without limitation: approval of the transaction by the
stockholders of both General Physics and GPS.

        The Company anticipates that if the aforementioned transaction is
consummated, it will own approximately 52% of the outstanding common stock of
General Physics, and if the Company were to exercise all of its warrants, it
will own approximately 58% of the outstanding common stock of General Physics.

        Although an agreement in principle has been reached, there   can be no
assurance that a definitive agreement will be successfully negotiated and
signed, or that the transaction will close as anticipated.

services are provided to a variety of domestic, European, and far eastern
clients.

Customers

GPS provides services to more than 320 customers,including several of the
largest companies in the United States. Other significant customers include
the Department of the Navy, the Department of the Air Force, the Department of
the Army, major automotive manufacturers, major defense contractors and other
United States Government agencies. Revenue from the United States Government
accounted for approximately 46% of GPS' revenue for the year ended December
31, 1993. However, such revenue was derived from many separate contractors and
subcontracts with a variety of Government agencies and contractors, that are
regarded by GPS as separate customers. United States Government contracts
generally are terminable by the United States Government at any time. However
no significant terminations have occurred.

Contracts

        GPS is currently providing services under more than 500 contracts, many
of which are General Service Agreements pursuant to which multiple purchase
orders are placed.  GPS'contracts with its customers provide for charges on a
time-and-materials basis, a fixed-price basis and a cost-plus-fee basis.

Competition

        The principal competitive factors in GPS's markets are the experience
and capability of technical personnel, performance, reputation and price.  GPS's
principal resource is its technical personnel.

GTS DURATEK, INC.
- -----------------

General

        GTS Duratek, Inc. ("Duratek") was incorporated in the State of Delaware 
in December 1982. At December 31, 1993 Duratek was an approximately 66%
controlled subsidiary of the Company.

        Duratek's operations consist of two operating groups: (i) 
"Environmental Services", engaged in cleanup of water and other liquids 
containing radioactive and/or hazardous (mixed waste) contaminants and 
in-furnance vitrification for long-term stabilization of such waste, and (ii)
"Consulting and Staff-Augmentation" services. Duratek provides services for
various utility, industry, government and commercial clients.

        During 1992, Environmental Services received a U.S. Department of Energy
("DOE") funded contract called MAWS for minimum additive waste stabilization.
This agreement enabled Environmental Services to further develop its
vitrification technology being used for processing actual mixed waste in a
demonstration at the DOE's Fernald facility.

        During 1993 Duratek designed, constructed and operated a 300
kilogram per day vitrification melter ("Duramelter") at Fernald under the
first phase of the MAWS project and began the second phase requiring
processing of actual mixed waste through the melter that it designed and built
at Fernald under varying controlled operating conditions. During 1993, Duratek
was also awarded a $1.2 million contract to study the chemical composition of
waste streams at DOE sites across the country to determine their suitability
for conversion into glass using the MAWS technology. Additionally, at the end
of 1993 Duratek was awarded a $13.9 million three year contract to stabilize
700,000 gallons of mixed waste sludges at the DOE's Savannah River nuclear
weapons production site. This project is Duratek's first commercial scale
project using its vitrification technology to convert the nuclear weapons 
by-product waste materials into glass for long term stabilization and storage.

        Consulting and Staff Augmentation revenues decreased by 12% due to 
lower utilization of contract services by its commercial nuclear power
customers.  This decrease resulted from an overall effort by electric utilities
to reduce operating costs in response to competitive pressures to become low
cost producers of electric power.  The group continued to provide support to
Duke Power, Vermont Yankee, New York Power Authority, Tennessee Valley
Authority, GPUN, the DOE, and to a number of other utility, commercial, and
government customers. Duke Power accounted for approximately 20% of Duratek's
revenue in 1993. In addition, new service contracts were won with Philadelphia
Electric and Duke Power. In response to the changing market conditions Duratek
implemented additional cost reduction efforts and expanded services to include
higher margin non-destructive examination (NDE) and professional health
physics training and consulting.

                                      6

Environmental Services

        Environmental Services provides products and services to support the
DOE and its prime contractors in research and development, development and
implementation of minimum additive vitrification (glass making) process for
long-term waste stabilization, waste water cleanup, advanced site remediation
processes, consulting, and analysis. Environmental Services' principal
products are its proprietary DURASILR ion exchange media, its Enhanced Volume
Reduction (EVRTM) processing system, Heat Enhanced Dewatering (HEDTM) system
and Integrated Nuclear Waste Removal System which is a combination of EVR and
HED. These systems and the DURASIL ion exchange media are similar to those
products formerly used in the domestic commercial nuclear power plant 
low-level radioactive waste business sold to Chem-Nuclear Systems, Inc. 
("Chem-Nuclear") in 1990. Duratek continues to sell DURASIL products to 
Chem-Nuclear.  Duratek also has the right to sell processing systems and ion 
exchange media to government agencies such as the DOE and Department of
Defense ("DOD") and to nuclear power plants outside the U.S. In addition to
liquid waste treatment, Environmental Services is engaged in the development
of in-furnace vitrification for long-term stabilization of mixed waste.

        DOE's Five Year Plan states that environmental cleanup and 
refurbishment of inactive DOE nuclear facilities is a critical objective. Many
of the remediation tasks at these facilities involve dealing with wastes that
are both radioactive and hazardous. Restrictions on disposal of these "mixed"
wastes and limited burial space further compound the problem. The DOE and its
prime contractors are looking for innovative new approaches for separating the
radioactive and hazardous components and for long-term stabilization of these
wastes. Management believes that its experience in mixed waste streams and its
newly developed vitrification technology give Duratek an advantage in this
market.

Consulting and Staff Augmentation

        Duratek's Consulting and Staff Augmentation Group ("Consulting")
provides technicians, specialists, and professionals in a wide range of
consulting, training and staff augmentation services for a broad base of
utility, industrial, commercial, and government clients.

        According to the Nuclear News publication of "The World List    of
Nuclear Power Plants", March 1993, there are 119 nuclear power  generating units
in the United States.  Of that number, approximately 107 are operational and the
remainder are in long-term shutdown or under construction.  To control costs,
utilities maintain their permanent staffs at the level needed for steady-state
power operations.  They supplement their full-time staffs during refueling and
maintenance outages with skilled contract personnel.  These temporary personnel
typically work under the general supervision of members of the full-time staffs
of utilities.

                                        7
<PAGE>
 
        Although services for operating nuclear power plants provides a
considerable market, the fact that no new plants have been ordered in over 10
years means that the current market will expand through incorporation of
changes required by new regulations; extensive overhaul required to extend the
life of aging plants; replacement of major components such as steam
generators; startup of newly built plants and those recovering from long-term
shutdown; and decommissioning of plants that have reached the end of their
useful lives.

        Building on its solid base of nuclear power industry clients, Duratek
has expanded its services in quality assurance/control, radiation protection,
computer and communications, and environmental technologies. Duratek's
potential client base has been expanded to include other industries,
government agencies and commercial businesses. Since many of the skills needed
for support at commercial nuclear power plants are readily transferable to the
DOE cleanup market, Duratek is also expanding its consulting and staff
augmentation services in that area.

GENERAL PHYSICS CORPORATION
- ---------------------------

        The Company currently owns approximately a 28% investment in General
Physics Corporation ("General Physics"). General Physics provides a wide range
of personnel training, engineering, environmental and technical support
services to the domestic commercial nuclear power industry and to the DOE and
DOD. General Physics believes it is a leader in the field of developing
training materials, conducting training programs and providing support
services to operators, technical staff and management personnel at commercial
nuclear power plants and at nuclear weapons production and waste processing
sites in the United States.

        General Physics currently provides services to more than 400 clients,
including eight of the largest electric power companies in the United States
and four prime contractors serving the DOE. During 1993, Westinghouse Savannah
River Company ("Westinghouse"), a prime contractor at DOE facilities,
accounted for approximately 23% of General Physics' revenue. No other customer
accounted for more than 10% of General Physics' revenue during 1993. Prior to
October, 1988, when it started its DOE Services business, the Company derived
virtually all of its revenue from contracts with nuclear utilities.

        From late 1988 through mid 1992, General Physics experienced growth in
revenue primarily from services provided to the DOE at its Savannah River site
under subcontracts with Westinghouse, and to a lesser extent from services
provided to the commercial nuclear power industry. During 1992 and 1993,
General Physics experienced lower levels of contract activity at DOE
facilities which resulted in declining revenue. General Physics Nuclear
Services revenue was adversely affected in 1993 by cost reduction efforts at
many commercial nuclear utilities which are expected to continue.
Environmental Services revenue increased slightly in 1993 and General Physics
was recently awarded a one-year contract with

                                      8
<PAGE>
 
four option years to provide environmental engineering support services at 
the DOD's Aberdeen Proving Ground.  This contract has a potential value of 
approximately $17 million if all option years are exercised.

        In January 1994, General Physics acquired substantially all of the
operating businesses of Cygna Energy Services (CES), other than its non-nuclear
seismic engineering business.  CES provides design engineering, seismic
engineering, systems engineering, materials management and safety analysis
services to the commercial nuclear power industry and to the DOE.

        In January 1994, General Physics also entered into a letter of intent 
to acquire substantially all of the assets and operations of GPS. GPS provides
a wide range of training, engineering, technical support and analytical
services to various commercial industries, fossil powered electric generating
plants and the DOD. Although an agreement in principle has been reached, there
can be no assurance that a definitive agreement will be successfully
negotiated or that the transaction will close as anticipated. See "Recent
Developments - General Physics' Corporation and GPS Technologies, Inc. Proposed
Transaction".

DISTRIBUTION GROUP

FIVE STAR GROUP, INC.
- ---------------------

        The Distribution Group, incorporated under the name Five Star Group,
Inc. ("Five Star"), is engaged in the wholesale distribution of home
decorating, hardware and finishing products. Five Star has three strategically
located warehouses and office locations, with approximately 380,000 square
feet of space in New Jersey, New York and Connecticut, which enables Five Star
to service the market from Maine to Virginia.

        Five Star is the largest distributor in the U.S. of paint sundry items, 
interior and exterior stains, brushes, rollers and caulking compounds and
offers products from leading manufacturers such as Olympic, Cabot, Thompson,
Dap, 3-M, Minwax and Rustoleum. Five Star distributes its products to retail
dealers which include discount chains, lumber yards, "do-it-yourself" centers,
hardware stores and paint suppliers principally in the northeast region. It
carries an extensive inventory of the products it distributes and provides
delivery generally within 48 to 72 hours from the placement of an order.

        The primary working capital investment for Five Star is inventory.
Inventory levels will vary throughout the year reflecting the seasonal nature of
the business.  Five Star's strongest sales are typically in March through
October because of strong seasonal consumer demand for its products.  As a
result, inventory levels tend to peak in the spring and reach their lowest
levels in late fall.

        The largest customer accounted for approximately 12% of Five Star's
sales in 1993 and its 10 largest customers accounted for approximately 29% of 
such sales.  No other 

                                      9
<PAGE>
 
customer accounted for in excess of 10% of Five Star's sales in 1993.  All such 
customers are unaffiliated companies and neither Five Star nor the Company has 
a long-term contractual relationship with any of them.

        Competition within the industry is intense.  There are much larger
national companies commonly associated with national franchises such as
Servistar and True Value as well as smaller regional distributors all of whom
offer similar products and services.  Additionally, in some instances
manufacturers will bypass the distributor and choose to sell and ship their
products directly to the retail outlet.  The principal means of competition for
Five Star are its strategically placed distribution centers and its extensive
inventory of quality name brand products.  Five Star will continue to focus its
efforts on supplying its products to its customers at a competitive price and on
a timely, and consistent basis.  In the future, Five Star will attempt to
acquire complementary distributors and to expand the distribution of its line of
private-label products sold under the "Five Star" name.

HEALTH CARE

INTERFERON SCIENCES, INC.
- -------------------------

        Interferon Sciences, Inc. ("ISI") is a biopharmaceutical  company
engaged in the manufacture and sale of ALFERON N Injection and the research and
development of other uses of ALFERON N Injection and other alpha 
interferon-based formulations for the treatment of certain viral diseases, 
cancers,and diseases of the immune system.

        ALFERON N Injection is the only natural-source, multi-species alpha
interferon product approved by the FDA for sale in the United States and is
approved for the intralesional treatment of refractory (resistant to other
treatment) or recurring external genital warts in patients 18 years of age or
older.

        On March 5, 1985, the United States Patent and Trademark Office
issued a patent to Hoffmann-La Roche Inc. ("Hoffmann") claiming purified human
alpha (leukocyte) interferon (regardless of how it is produced).  ISI obtained a
non-exclusivelicense from Hoffmann which allows ISI to make, use, and sellin the
United States, without a potential patent infringement claim from Hoffmann, (i)
ALFERON N Injection for the treatment of genital warts, (ii) injectable
formulations of interferon alfa-n3 (which is the same active ingredient
contained in ALFERON N Injection) for the treatment of patients who are
refractory to recombinant interferon therapy, (iii) low dose oral formulations
of alpha interferon for the treatment of human disease, and (iv) topical
formulations of interferon alfa-n3 (which is the same active ingredient
contained in ALFERON N Injection).  Hoffmann presently  owns approximately 3% of
the common stock of ISI.

        ALFERON N Injection is marketed and distributed in the United States
exclusively by Purdue Pharma L.P.("Purdue"), utilizing the sales force of The
Purdue Frederick Company, a privately-held United States pharmaceutical company.
In addition, ISI has exclusive 

                                    10
<PAGE>
 
marketing and distribution agreements with Mundipharma Pharmaceutical Company 
in Canada and with Industria Farmaceutica Andromaco in Mexico. ISI has
anoption to reacquire the United States, Canadian, and Mexican marketing and
distribution rights under certain terms and conditions. Submissions for
regulatory approval to sell ALFERON N Injection have been filed in Austria,
Canada, Israel, Mexico and the United Kingdom.

        At the present time, alpha interferon injectable products are approved
for 17 different medical uses in 63 countries. In 1993, the worldwide alpha
interferon injectable market was estimated to be over $1 billion. In an effort
to expand the market for ALFERON N Injection in the United States and obtain
additional regulatory approvals around the world, ISI is presently conducting
three multi-center randomized, open dose ranging studies with patients
infected with hepatitis C virus. In addition, based upon favorable results
from an in vitro study and a Phase 1 clinical study conducted at Walter Reed
Army Institute of Research in Bethesda, Maryland on 20 asymptomatic HIV
infected patients, ISI is planning a multi-center, randomized, controlled
clinical trial with asymptomatic HIV-infected patients. ISI is also planning
to conduct clinical trials utilizing ALFERON N Injection for the treatment of
Kaposi's sarcoma in patients with AIDS and hepatitis B.

        Additional products under development by ISI include ALFERON N Gel and
ALFERON LDO. ALFERON N Gel is a topical interferon preparation which ISI
believes has potential in the treatment of cervical dysplasia, recurrent
genital herpes, other viral diseases, and cancers. A clinical trial using
ALFERON N Gel for the treatment of patients with cervical dysplasia is
currently underway at Columbia Presbyterian Medical Center. ALFERON LDO is a
low dose oral liquid alpha interferon preparation which ISI believes has
potential for treating the symptoms of patients infected with the HIV virus
and other viral diseases. ISI conducted two clinical trials using ALFERON LDO
on patients infected with HIV virus at New York's Mount Sinai Hospital. The
National Institute of Allergy and Infectious Disease ("NIAID") is planning to
conduct a randomized, double-blind, placebo controlled clinical study with low
dose alpha interferons administered orally (including ALFERON LDO) to
determine interferon's effect on HIV related symptoms.

        On May 28, 1993, David Blech, the Chief Executive Officer, sole
shareholder and a director of D. Blech & Company, Incorporated ("DBC"), and
ISI entered into a Purchase Agreement (the "Purchase Agreement"), pursuant to
which David Blech or his designees purchased for $4.00 per unit, an aggregate
of 2,500,000 units ("Units"), each Unit consisting of two shares of common
stock, one Class A Warrant to purchase one share of common stock at an
exercise price of $3.25 per share and one Class B Warrant to purchase one
share of common stock at an exercise price of $5.00 per share. The Class A
Warrants and the Class B Warrants expire on August 31, 2000.

        Pursuant to the Purchase Agreement, a 10-year Voting Agreement (the
"Voting Agreement") among David Blech, the Company, Five Star and MXL became
effective as of May 28, 1993 pursuant to which the Company, Five Star and MXL
agreed to (a) vote all of their shares of common stock (an aggregate of
6,985,148 shares as of the date hereof), for

                                 11
<PAGE>
 
the election of the Blech Nominees as directors of ISI unless Blech or his
designees dispose of more than 1,000,000 shares of Common Stock and (b)
restrict transfer of the Common Stock held by them for one year, subject to
certain exceptions. Pursuant to the Voting Agreement, Mr. Blech and any other
purchasers under the Purchase Agreement agreed to vote for the election of two
nominees of NPDC as directors of the Company unless NPDC, MXL and Five Star
dispose of more than 2,000,000 shares of Common Stock.

       Concurrently with the execution of the Purchase Agreement, ISI entered
into a Consulting Agreement with DBC under which ISI agreed to pay $100,000
per year, payable monthly, to DBC for advisory services with respect to the
Company's field of interest and business, strategic and commercial matters
related to the biotechnology industry. The term of the Consulting Agreement
was one year and commenced on June 1, 1993.

OPTICAL PLASTICS GROUP
- ----------------------

        The Optical Plastics Group is engaged in the manufacture of molded and
coated optical products, such as shields and face masks and non-optical plastic
products through the Company's wholly owned subsidiary MXL Industries, Inc.
("MXL").

        MXL is a state-of-the-art injection molder and precision coater of large
optical products such as shields and face masks and non-optical plastics.  MXL
believes that the principal strengths of its business are its state-of-the-art
injection molding equipment, advanced production technology, high quality
standards, and on time deliveries.  Through its Woodland Mold and Tool Division,
MXL also designs and engineers state-of-the-art injection molding tools as well
as providing a commodity custom molding shop.

        As the market for optical injection molding, tooling and coating is
focused, MXL believes that the combination of its proprietary "Anti-Fog"
coating, precise processing of the "Anti-Scratch" coatings, and precise
molding and proprietary grinding and polishing methods for its injection tools
will enable it to increase its sales in the future and to expand into related
products.

                                       12
<PAGE>
 
        MXL uses only polycarbonate resin to manufacture shields, face masks and

("Eastern") is engaged in contract manufacturing for the electronics industry.
Eastern offers a variety of services to its customers ranging from printed
circuit board assemblies, to in-circuit testing, to functional testing, to
turnkey production and to final system production.  Eastern's customers are
among the largest United States electronics companies.

        There is significant competition within the electronics industry for 
contract manufacturing from much larger national companies as well as smaller
companies. While the electronics industry at large is experiencing a downturn
in business, Eastern feels that the lessening of off-shore competition and
"just in time" manufacturing requirements will enable it to compete more
effectively in the changing environment. The principal means of competition
for Eastern are its twenty two years of experience in printed circuit board
assembly, state-of-the-art automatic insertion, surface mount equipment and
state-of-the-art in circuit test equipment.

Item 7.  Management's Discussion and Analysis of 
         ---------------------------------------
         Financial Condition and Results of Operations
         ---------------------------------------------


RESULTS OF OPERATIONS

Overview

During 1993, the Company took steps to significantly reduce its long-term
debt. The Company, through an Exchange Offer for a large portion of its Swiss
Denominated Debt (See Note 9(a) to Notes to Consolidated Financial
Statements), as well as other repurchases from various bondholders throughout
1993, was able to reduce its long-term debt by approximately $20,583,000. As a
result of the reduction in long-term debt, the Company will be able to reduce
its annual interest expense by approximately $2,100,000. Due to the inclusion
of a portion of the Company's shares of common stock of Interferon Sciences,
Inc. (ISI) as part of the consideration in the Exchange Offer in the third
quarter of 1993, the Company currently owns less than 50% of ISI (36%), and
therefore now accounts for the results of ISI on the equity basis. In 1993,
the Company realized an extraordinary gain, net of taxes, on the early
extinguishment of debt of $1,819,000. In 1993, the Company also incurred
reduced interest expense at the corporate level on the Company's long-term
Swiss Debt obligations due to the Company's continuing practice of
repurchasing and reducing its Swiss Debt. In addition, the Company incurred
reduced interest relating to short-term borrowings due to reduced borrowings
at lower rates of interest. In 1993, the loss before income taxes and
extraordinary item was $8,371,000, as compared to a loss of $13,178,000 in
1992 and income of $1,157,000 in 1991. The decrease in the loss in 1993 is due
to several factors. As a result of the Exchange Offer discussed above, the
Company realized a $3,795,000 gain from the transfer of a portion of the
Company's holdings of shares of ISI and GTS Duratek, Inc.'s (Duratek) common
stock. In addition, the Company realized a gain of $1,353,000 on the issuance
of common stock and common stock warrants by Duratek, relating to its
acquisition of an option to acquire certain technologies relating to the
vitrification of certain medical and hazardous wastes. The Health Care and the
Electronics Groups experienced reduced operating losses in 1993. The Health
Care Group which is comprised of the results of ISI experienced reduced
operating losses in 1993 as a result of ISI being accounted for on the equity
basis commencing in the third quarter of 1993. The Electronics Group, which is
Eastern Electronics Manufacturing Corporation (Eastern), the Company's
electronic assembly and manufacturing subsidiary, incurred reduced operating
losses as a result of their successful efforts to reduce overhead and costs of
sales. The above improvements in 1993 were partially offset by reduced
operating profits at the Distribution and Physical Science Groups, in addition
to a foreign currency transaction gain of $901,000 realized in 1993 as
compared to a net foreign currency transaction gain of $3,362,000 realized in
1992, relating to the Company's decision not to hedge its Swiss denominated
debt. The Distribution Group, which is the Five Star Group, Inc. (Five Star),
the Company's distributor of home decorating, hardware and finishing products
had reduced operating profits as a result of reduced gross margin percentages
and increased operating

                                     19

costs. The Physical Science Group, which is comprised of GPS Technologies Inc.
(GPS), a 92% owned subsidiary, and GTS Duratek, Inc. (Duratek), a 66% owned
subsidiary, had reduced operating profits as a result of losses incurred by
Duratek due to reduced revenues and gross margin percentages achieved. The
Optical Plastics Group, which is MXL Industries, Inc. (MXL), the Company's
injection molding and coating subsidiary, had a marginal decrease in operating
profits.

During 1992, the loss before income taxes and extraordinary items was
$13,178,000 compared to income of $1,157,000 in 1991. The change from a profit
in 1991 to a loss in 1992 was primarily the result of the public offering by
General Physics Corporation (GP) in October 1991, through which the Company
sold 68% of its GP common stock and recognized a gain on the transaction of
$18,844,000. The Company currently owns approximately 28% of GP. The effect of
the gain on GP was partially offset by improved operating results achieved in
1992 by the remaining companies within the Physical Science Group, GPS and
Duratek. At the corporate level, improved operating results in 1992 were
partially the result of gains recognized on the sale of certain investments
and the continuing reduction in interest expense as a result of reduced 
short-term borrowings, lower rates of interest on the Company's variable rate
obligations and reduced interest on the Company's Swiss Debt obligation due to
the Company's continuing practice of repurchasing its Swiss Debt from time to
time. The improved operating results within the Physical Science Group were
due to both GPS and Duratek achieving operating profits in 1992 as opposed to
operating losses in 1991. GPS achieved a significant turnaround as a result of
reduced losses at its subsidiary, GP International Engineering & Simulation,
Inc. (GPI), an operating profit generated for the first time by its subsidiary
GP Environmental Services, Inc. (GPE) and an overall improvement within the
core businesses of GPS. Duratek showed an improvement in operations during
1992 as a result of increased sales and gross profit in both its Environmental
Services and Consulting and Staff Augmentation businesses, as well as the
impact of the effort in the latter half of 1991 to consolidate and streamline
its administrative structure. The improvements in operations achieved by the
current members of the Physical Science Group and at the corporate level were
partially offset by an increased operating loss at the Electronics Group and
reduced operating profits at the Optical Plastics Group. The Electronics
Group, incurred increased operating losses due to reduced sales and inceased
operating costs and the effect of reserves taken for obsolete inventory. The
Optical Plastics Group had a small decrease in operating profit as a result of
weakness in the precision tooling part of its business,as well as reduced
orders from a number of MXL's establishedcustomers in the beginning of 1992.
The Health Care Group's operating loss and the Distribution Group's operating
profit remained virtually unchanged in 1992.

Sales

Consolidated sales from continuing operations decreased by $6,082,000 in 1993
to $189,683,000 as a result of reduced sales in the Physical Science, Health
Care and Electronics Groups, partially offset by increased sales achieved by
the Distribution Group. Sales decreased by $63,168,000 in 1992, to
$195,765,000, as a result of the transfer in April 1991 of a majority interest
in American White Cross, Inc. (AWC), formerly NPM

                                     20
<PAGE>
 
Healthcare,Inc., in which the Company currently has a 14% interest, and the
public offering by GP in October 1991, which resulted in GP and AWC no longer
being consolidated entities. The decrease in 1992 was partially offset by
increased sales within the Distribution Group and by the remaining companies
in the Physical Science Group.

The Physical Science Group sales decreased from $162,727,000 in 1991 to
$109,303,000 in 1992 and to $102,977,000 in 1993. The reduced sales of
$6,326,000 in 1993 were primarily attributable to reduced sales achieved by
Duratek as a result of reduced revenues generated by its consulting and staff
augmentation business, as a result of a reduced demand for services provided
to nuclear utilities. In addition, Duratek's sales decreased as a result of
reduced revenues achieved by the environmental services business due to delays
in the award of certain technology contracts by the Department of Energy.
During 1992, sales decreased by $53,424,000, due to the public offering by GP
on October 3, 1991, from which time the results of GP were accounted for on
the equity basis, since the Company's percentage of ownership was reduced to
approximately 28%. In 1991, the Physical Science Group included sales of
$62,325,000 for GP. The loss of GP's sales in 1992 was partially offset by
increased sales at both GPS and Duratek. Duratek generated increased sales in
1992 as a result of work performed on two new environmental technology
projects, as well as an increase in services provided by the consulting and
staff augmentation business. GPS generated increased revenues in new business
areas such as environmental analytical services and full scope simulation.
These increases at GPS were partially offset by a reduction in revenue for
certain subcontracts, which terminated in 1991, for construction management
services provided to the Department of the Army.

The Distribution Group sales increased from $64,788,000 in 1991 to $68,450,000
in 1992 and to $74,109,000 in 1993. The increase of $5,659,000, or 8% in 1993
was due to reduced competition in one of Five Star's geographic regions, as
well as continued growth in the hardware business, which was introduced in
1992. The increase of $3,662,000, or 6%, in 1992 was attributable to the
introduction during the year of a new line of hardware supplies.

The Health Care Group sales decreased from $14,607,000 in 1991 to $4,042,000
in 1992 and to zero in 1993. The reduction in sales in 1993 was due to ISI not
having any sales of its product, ALFERONR N Injection, in 1993. In January
1994, ISI received an order for 45,000 vials of ALFERONR N Injection from the
Purdue Frederick Company (Purdue). As a result of the Exchange Offer, through
which the Company's interest in ISI fell below 50%, ISI is currently being
accounted for on the equity basis. The $10,565,000 reduction in sales in 1992
was due to the transfer on April 8, 1991 of a majority interest in AWC,
partially offset by increased sales by ISI of ALFERONR N Injection to its
marketing partner, Purdue. In December 1991, Purdue agreed to purchase an
aggregate of 45,000 vials of ALFERONR N Injection from the Company over
approximately a six month period which commenced in March 1992 and was
completed in September 1992.

The Optical Plastics Group sales decreased from $9,454,000 in 1991 to
$7,862,000 in 1992 and to $7,817,000 in 1993. The decreased sales in 1992 was
due to weakness at MXL's

                                     21
<PAGE>
 
precision tooling division, as well as reduced orders from a number of MXL's
established customers in the beginning of 1992.

The Electronics Group sales decreased from $7,151,000 in 1991 to $5,968,000 in
1992 and to $3,836,000 in 1993. The decreased sales in 1992 and the continued
weakness in 1993 was the result of the weakness in the electronics industry
and Eastern's plan to concentrate its efforts on sales to customers who
provide more profitable margins.

Gross margin

Consolidated gross margin was $36,013,000 or 14% of net sales in 1991,
$29,772,000 or 15% of net sales in 1992 and $27,519,000 or 15% in 1993. In
1993, the decrease in gross margin of $2,253,000 occurred within the Health
Care, Distribution and Physical Science Groups. In 1992, the decrease in gross
margin of $6,241,000 occurred primarily in the Physical Science Group as a
result of the public offering by GP in October 1991, and to a lesser extent,
in the Health Care Group due to the transfer in April 1991 of a majority
interest in AWC in which the Company currently has a 14% interest. The reduced
gross margin in 1992 was partially offset by increased gross margin achieved
by the Distribution Group as a result of increased sales.

The Physical Science Group gross margin decreased from $18,370,000, or 11% of
net sales in 1991 to $13,728,000 or 13% of net sales in 1992 and to
$12,941,000, or 13% of net sales in 1993. In 1993, the reduced gross margin
was primarily attributable to reduced gross margins achieved by Duratek as a
result of reduced sales as well as a decrease in the gross margin percentage
achieved within Duratek's consulting and staff augmentation business because
of increasing competitive pressures within the industry. The reduced gross
margin achieved by Duratek was partially offset by GPS, which generated
increased gross margins as a result of an improved mix of services during
1993. In 1992, the decreased gross margin was due to the public offering by GP
in October 1991, partially offset by increased gross margins at Duratek and
GPS. The increased gross margin dollars and percentage at GPS was due to
increased sales, significant profit improvements at GPI and GPE during 1992,
as well as an improved mix of services performed at higher margins within the
core businesses. Duratek achieved increased gross margins in 1992 as a result
of increased revenues generated by its environmental technology projects.

The Distribution Group gross margin increased from $11,679,000 or 18% in 1991
to $12,355,000 or 18% of sales in 1992 and decreased to $11,718,000 or 16% in
1993. In 1993, the reduced gross margin was the result of the reduced gross
margin percentage achieved in 1993. The reduced gross margin percentage in
1993 was the result of a change in the product mix as well as competitive
price pressures within the industry. In 1994, the Group has started taking
steps to reduce its costs of sales in order to improve its operating margins
in the future. In 1992, the increased gross margin was the result of increased
sales due to the introduction of a new line of hardware products.

   The Health Care Group gross margin decreased from $2,509,000 or 17% of net
sales in 

                                     22
<PAGE>
 
1991 to $358,000 or 9% of net sales in 1992 and to $(699,000) in 1993. The
negative gross margin in 1993 was the result of facility costs incurred by
ISI, notwithstanding the suspension of production, and lack of sales of
ALFERONR N Injection during 1993. The decrease in gross margin in 1992 was the
result of the transfer on April 8, 1991 of a majority interest in AWC, as
discussed above. The reduced gross margin percentage in 1992 is attributable
to the low gross margin percentages achieved by ISI due to the write-down of
inventory to its estimated net realizable value, as a result of increased unit
production costs caused by limited production volumes.

The Optical Plastics Group gross margin decreased from $3,231,000 or 34% of
net sales in 1991 to $2,740,000 or 35% of net sales in 1992 and to $2,642,000
or 34% of net sales in 1993. The small decrease in gross margin in 1993 was
the result of marginally reduced sales and gross margin percentage. In 1992,
the reduced gross margin was the result of reduced sales volume.

The Electronics Group gross margin increased from $221,000 or 3% of net sales
in 1991 to $561,000 or 9% of net sales in 1992 and decreased to $546,000 or
14% of net sales in 1993. The small decrease in gross margin in 1993 and
increased gross margin in 1992, in spite of reduced sales at Eastern in both
years, was attributable to the continuing improvement in gross margin
percentages as a result of a better product mix, a reduction in the fixed
manufacturing costs and improved operating efficiencies.

Investment and other income, net
Investment and other income was $2,790,000 in 1991, $6,221,000 in 1992 and
$3,358,000 in 1993, respectively. In 1993 the decrease in investment and other
income, net was primarily attributable to a net foreign currency transaction
gain of $901,000 in 1993 as compared to a gain of $3,362,000 in 1992. In
addition, in 1993 the Company realized reduced revenues relating to interest
income, and in the equity in earnings of 20% to 50% owned subsidiaries as
compared to 1992. These decreases were partially offset by reserves taken and
losses realized by the Company on certain assets and investments in 1992. In
1992, the increase in investment and other income, net was primarily due to
two factors. In 1992, the Company realized increased gains on the sales of
certain investments, and recognized an expense for reserves taken and losses
realized on certain assets of $1,336,000 in 1992 as compared to $4,774,000 in
1991. In 1992, the Company realized a net foreign currency transaction gain of
$3,362,000, as compared to a gain of $3,042,000 in 1991. The reserves were
taken in 1992 and 1991 due primarily to reduced values and impairments
relating to long-term investments and related assets accounted for on the cost
basis. The Company evaluates its long-term investments at least annually. An
investment is written down or written off if it is judged to have sustained a
decline in value which is other than temporary. During 1991, a 19% interest in
and advances to a vendor and distributor of pay telephones was written down by
$3,100,000, to an estimated residual value of $175,000, since the telephone
company ceased marketing its principal product in 1991. This resulted from (a)
the loss by the telephone company of two major vending accounts in 1991, which
substantially reduced revenues and (b) the telephone company's effort to sell
telephones as well as to vend them

                                     23
<PAGE>
 
was unsuccessful in 1991. Based upon the fact that the remaining vending
revenues were insufficient to support operations the telephone company ceased
operations. In 1992, the estimated residual value of $175,000 of this
investment, which was based upon estimated proceeds on liquidation of
telephone equipment, was written off since it was determined that such sales
could not be consummated. Additionally, in 1992, the Company fully reserved
its investment of $305,000 in a medical blood center company. The blood center
company ceased operations in 1992 as its major investor, a large financial
institution decided to no longer provide financing and working capital. In
1991 and prior years, the medical blood center company received substantial
funding for its centers and the financial institution provided working capital
and equity financing. In both 1991 and 1992, a number of other relatively
small investments were written off or written down because the Company's
periodic evaluations indicated declines in value which were judged to be other
than temporary.

At December 31, 1993, there was an aggregate of SFr. 25,398,000 of Swiss
denominated indebtedness outstanding, of which SFr. 23,680,000 represents
principal amount outstanding and SFr. 1,718,000 represents interest accrued
thereon. Foreign currency valuation fluctuations may adversely affect the
results of operations and financial condition of the Company. In order to
protect itself against currency valuation fluctuations, the Company has at
times swapped or hedged a portion of its obligations denominated in Swiss
Francs. At December 31, 1993, the Company had not hedged its Swiss Franc
obligations. If the value of the Swiss Franc to the U.S. Dollar increases, the
Company will recognize transaction losses on the portion of its Swiss Franc
obligations which are not hedged. On December 31, 1993, the value of the Swiss
Franc to the U.S. Dollar was 1.485 to 1. There can be no assurance that the
Company will be able to swap or hedge obligations denominated in foreign
currencies at prices acceptable to the Company or at all. The Company will
continue to review this policy on a continuing basis.

Selling, general, and administrative expenses
Selling, general and administrative expenses (SG&A) decreased from $38,356,000
in 1991 to $36,274,000 in 1992 and to $35,600,000 in 1993. In 1993, the
decrease in SG&A was primarily attributable to ISI being accounted for on the
equity basis during the third quarter of 1993, as a result of the Exchange
Offer discussed above, in which the Company's interest in ISI fell below 50%.
In addition, the Electronics Group also experienced reduced SG&A expenses as a
result of reduced personnel requirements due to reduced sales in 1993 and
Eastern's continuing effort to streamline its organization. The reduced SG&A
within the Health Care and Electronics Groups in 1993 were partially offset by
increased SG&A incurred by the Distribution and Physical Science Groups. The
increased SG&A at The Physical Science Group was due to increased operating
costs and the increased SG&A at the Distribution Group was the result of the
large increase in sales which led to increased selling expenses, as well as
additional costs incurred by Five Star to support the growth in sales. The
Optical Plastics Group had a marginal increase in SG&A in 1993. In 1992, the
decrease in SG&A expenses was primarily due to decreases in the Health Care
Group and the Physical Science Group as a result of the transfer on April 8,
1991 of a majority interest in AWC and

                                     24
<PAGE>
 
the public offering by GP in October 1991, respectively. The decrease was
partially offset by increased SG&A within the Distribution Group as a result
of Five Star's expansion into the hardware supply distribution business and
increased SG&A within the Electronics Group due to costs connected with
Eastern's efforts to restructure its business operations.

Research and development costs
The Company's research and development activities are conducted both
internally and under various types of arrangements at outside facilities.
Research and development costs, which are primarily attributable to ISI, were
$4,651,000, $4,645,000 and $2,847,000 for 1991, 1992, 1993, respectively. In
1993, the reduced research and development costs were the result of the
Company's ownership in ISI falling below 50% in the third quarter of 1993, due
to the Exchange Offer discussed above, and therefore, the Company began
accounting for ISI on the equity method from that time. In 1992, ISI
experienced increased research and development costs because of increased
levels of research on ALFERONR N Gel, ALFERONR LDO and other proprietary
research. The increased spending at ISI in 1992 was offset by reduced spending
on various corporate projects.

Interest expense
Interest expense aggregated $15,579,000 in 1991, $11,044,000 in 1992 and
$8,325,000 in 1993. The reduced interest expense in 1992 and the further
reduction in 1993, was the result of the Company's continuing successful
effort to reduce its interest expense at the corporate level due to reduced
short-term borrowings, lower rates of interest on the Company's variable rate
obligations and reduced interest on the Company's Swiss Debt obligations due
to the Exchange Offer in 1993 and the Company's practice of repurchasing Swiss
Debt from time to time.

Income taxes and extraordinary item
Income tax benefit (expense) from operations for 1991, 1992 and 1993 was
$(549,000), $(427,000) and $575,000, respectively.

In 1993, the Company recorded an income tax benefit of $1,043,000, of which
$973,000 relates to Federal income taxes, in continuing operations as a result
of the income tax expense allocated to the extraordinary gain recognized on
the early extinguishment of debt under the provisions of FASB No. 109.

In 1992, the Company's loss before income taxes from operations exceeded its
gains from extraordinary items: therefore, pursuant to accounting policies of
the Company, then in effect under APB No. 11, "Accounting for Income Taxes",
no income tax expense applicable to such extraordinary gains was recognized.
The income tax expense for 1992 of $427,000 represents state and  local income
taxes.

In 1991, despite the Company's $1,157,000 income before income taxes from
operations, no Federal income tax expense was recognized. This is due
principally to significant permanent differences between financial and tax
reporting of 1991 transactions, including the

                                     25
<PAGE>
 
elimination for tax purposes of the $18,844,000 gain on the sale of GP stock,
net of a gain recognized only for tax purposes upon ISI ceasing to be a member
of the Company's consolidated Federal income tax return group on May 31, 1991.
The income tax expense for 1991 of $549,000 represents state and local income
taxes.

As of December 31, 1993, the Company has approximately $34,770,000 of
consolidated net operating losses available for financial statement reporting
purposes.

Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes," was adopted by the Company in 1993 on a prospective basis. (See Note
15 to the Consolidated Financial Statements). This standard requires that
deferred income taxes be recorded following the liability method of accounting
and adjusted periodically when income tax rates change. As of December 31,
1993, the Company was not carrying any deferred tax accounts. Adoption of the
new Statement did not have a material effect on the Company's financial
condition or results of operations.

Liquidity and capital resources
At December 31, 1993, the Company had cash, cash equivalents and marketable
securities totaling $10,976,000. GPS and Duratek had cash, cash equivalents
and marketable securities of $547,000 at December 31, 1993. The minority
interests of these companies are owned by the general public, and therefore,
the assets of these subsidiaries have been dedicated to the operations of
these companies and may not be readily available for the general corporate
purpose of the parent.

The Company believes that it has sufficient cash, cash equivalents and
marketable securities and borrowing availability under existing and potential
lines of credit to satisfy its cash requirements until the first scheduled
maturity of its Swiss Franc denominated indebtedness on March 1, 1995.
However, in order for the Company to meet its long-term cash needs, which
include the repayment of $12,757,000 of Swiss Franc denominated indebtedness
scheduled to mature in 1995 and $7,115,000 of Swiss Franc denominated
indebtedness which is scheduled to mature in 1996, the Company must obtain
additional funds from among various sources. The Company has historically
reduced its long-term debt through the issuance of equity securities in
exchange for long- term debt. In addition to its ability to issue equity
securities, the Company believes that it has sufficient marketable long-term
investments, as well as the ability to obtain additional funds from its
operating subsidiaries and the potential to enter into new credit
arrangements. The Company reasonably believes that it will be able to
accomplish some or all of the above transactions in order to fund the
scheduled repayment of the Company's long-term Swiss debt in 1995.

For the year ended December 31, 1993, the Company's working capital decreased
by $11,653,000 to $33,224,000, reflecting the effect of the Company's interest
in ISI falling below 50%, and being accounted for on the equity basis.
Consolidated cash and cash equivalents decreased by $6,945,000 to $10,976,000
at December 31, 1993.

                                     26
<PAGE>
 
The decrease in cash and cash equivalents of $6,945,000 in 1993 primarily
resulted from the effect of the Company's interest in ISI falling below 50%,
and being accounted for on the equity basis as well as cash used, in
operations of $2,507,000, investing activities of $2,593,000 and financing
activities of $1,845,000. Cash used in operations was primarily required to
fund the operating loss for the year. The cash used in investing activities
was for increases in certain investments and for investment in property, plant
and equipment and intangible assets. Financing activities consisted primarily
of repayments and reductions in short-term borrowings and repayments of long-
term debt, offset by proceeds from short-term borrowings and long-term debt.
At December 31, 1993, the Company at the parent company level had
substantially exhausted its ability to borrow funds from its subsidiaries
under their respective line of credit arrangements.

The Company's principal manufacturing facilities were constructed subsequent
to 1976 and management does not anticipate having to replace major facilities
in the near term. As of December 31, 1993, the Company has not contractually
committed itself for any other new major capital expenditures.

                     INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
National Patent Development Corporation:


We have audited the consolidated financial statements of National Patent
Development Corporation and subsidiaries as listed in the accompanying index.
These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of National
Patent Development Corporation and subsidiaries at December 31, 1993 and 1992,
and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 1993, in conformity with generally
accepted accounting principles.

As discussed in Note 15 the Company has adopted SFAS No. 109, "Accounting for
Income Taxes", as of January 1, 1993.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Summary of significant accounting policies

Principles of consolidation and investments. The consolidated financial
statements include the operations of National Patent Development Corporation and
its majority-owned subsidiaries (the Company). Investments in 20% - 50% owned
companies are accounted for on the equity basis, and marketable equity
securities of less than 20% owned companies are accounted for at the lower of
aggregate cost or market. Other investments in less than 20% owned companies are
accounted for on the cost basis. All significant intercompany balances and
transactions have been eliminated in consolidation.

Statements of cash flows. For purposes of the statement of cash flows, the
Company considers all highly liquid instruments with maturities of three months
or less from purchase date to be cash equivalents.

Marketable securities. Marketable securities at December 31, 1992 consisted of
United States Government obligations, carried on the balance sheet at cost by
the Company. The market value of marketable securities at December 31, 1992 was
$4,606,000.

Inventories. Inventories are valued at the lower of cost or market, principally
using the first-in, first-out (FIFO) method.

Foreign currency transactions. The Company's Swiss Bonds (see Note 9) are
subject to currency fluctuations and the Company has hedged portions of such
debt from time to time. During the years ended December 31, 1993, 1992, and
1991, the Company realized foreign currency transaction gains of $901,000,
$3,362,000 and $3,042,000, respectively. These amounts are included in
investment and other income, net. At December 31, 1993, the Company had not
hedged its Swiss Franc obligations.

Contract revenue and cost recognition. The Company provides services under time-
and-materials, cost-plus-fixed-fee, and fixed-price contracts. Revenue from
contracts is recognized on the percentage-of-completion method as costs are
incurred and includes estimated fees at predetermined rates. Differences between
recorded costs, estimated fees, and final billings are recognized in the period
in which they become determinable. Costs and estimated earnings in excess of
billings on uncompleted contracts are recorded as an asset. Billings in excess
of costs and estimated earnings on uncompleted contracts are recorded as a
liability. Generally, contracts provide for the billing of costs incurred and
estimated fees on a monthly basis and do not provide for retainage. Retainages,
amounts subject to future negotiation, amounts expected to be collected after
one year, and amounts related to claims are not material.

1. Summary of significant accounting policies (Continued)

Property, plant, and equipment. Property, plant, and equipment are carried at
cost. Major additions and improvements are capitalized while maintenance and
repairs which do not extend the lives of the assets are expensed currently. Gain
or loss on the disposition of property, plant, and equipment is recognized in
operations when realized.

Depreciation. The Company provides for depreciation of property, plant and
equipment primarily on a straight-line basis over the following estimated useful
lives:

</TABLE>

Intangible assets. The excess of cost over the fair value of net assets of
businesses acquired is recorded as goodwill and is amortized on a straight-line
basis generally over periods ranging from 5 to 40 years. The Company capitalizes
costs incurred to obtain and maintain patents and licenses. Patent costs are
amortized over the lesser of 17 years or the remaining lives of the patents, and
license costs over the lives of the licenses. The Company also capitalizes costs
incurred to obtain long-term debt financing. Such costs are amortized on an
effective yield basis over the terms of the related debt and such amortization
is classified as interest expense in the Consolidated Statements of Operations.

The periods of amortization of goodwill are evaluated at least annually to
determine whether events and circumstances warrant revised estimates of useful
lives. This evaluation considers, among other factors, expected cash flows and
profits of the businesses to which the goodwill relates. Goodwill is written off
when it becomes evident that it has become permanently impaired.

Treasury stock. Treasury stock is recorded at cost. Reissuances of treasury
stock are valued at market value at the date of reissuance. The cost of the
treasury stock is relieved from the treasury stock account and the difference
between the cost and market value is recorded as additional paid in capital.

1. Summary of significant accounting policies (Continued)

Sales of stock by a subsidiary. The Company records in the Consolidated
Statement of Operations any gain or loss realized when a subsidiary sells its
shares at an offering price which differs from the Company's carrying amount per
share of such subsidiary's stock.

Income taxes. The Company files a consolidated Federal income tax return that
includes each domestic subsidiary in which the Company has at least 80% voting
control. The Company adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes", effective Janaury 1, 1993. Adoption of the
new Statement did not have a significant effect on the Company's financial
condition or results of operations.

Income (loss) per share. Per share data is based on the weighted average number
of shares outstanding, including Class B capital stock, and dilutive common
stock equivalents. Presentation of fully diluted earnings per share is not
required because the effect is less than 3% or is antidilutive. The weighted
average number of shares outstanding for the years ended December 31, 1993, 1992
and 1991 were 17,125,900, 15,771,301 and 15,393,781, respectively.

2. GPS Technologies, Inc.

On October 3, 1991, General Physics Corporation (GP)completed a public of 4
million shares of common stock at a price of $13 per share. The Company offered
3,846,540 shares of stock, and the remainder was offered by certain non-
affiliated shareholders. The Company received net proceeds after expenses of
$43,997,000, and from the proceeds was required to make several repayments of
long-term debt and short-term borrowings. The Company repaid $16,735,000 of
short-term borrowings, $5,163,000 of long-term debt and $2,039,000 of accrued
interest payable on its Swiss Convertible Bonds. Included in expenses were
legal, printing and accounting costs, bonuses paid to key employees of the
Company, as well as other costs. The Company recognized a gain of $18,844,000
from this transaction.

2. GPS Technologies, Inc. (Continued)

In connection with the public offering, a reorganization was effected on
September 25, 1991 whereby GP transferred certain operations and related assets
and liabilities to a new subsidiary, GPS Technologies, Inc. (GPS), formerly
named General Physics Services Corp. GP retained the business, assets and
liabilities of its Nuclear Services, Department of Energy Services and
Environmental Services Groups. Included among the businesses and assets
transferred to GPS were certain leases of property and equipment, and two
finance subsidiaries that own power plant control room simulators. As a result
of the public offering and the reorganization, the Company owns approximately
28% of GP and 92% of GPS. The financial position and results of operations of GP
are included in the consolidated accounts of the Company for all periods
presented through September 30, 1991. On October 3, 1991, the Company's
ownership fell below 50%. Thereafter, the Company's investment in GP has been
accounted for on the equity basis and the Company's share of GP's income (loss)
for the three months ended December 31, 1991 and years ended December 31, 1992
and 1993 in the amount of $432,000, $(144,000) and $316,000, respectively, after
the amortization of the underlying goodwill, is included in the caption
"Investment and other income, net" appearing in the consolidated statements of
operations. The financial position and results of operations of GPS are included
in the consolidated accounts of the Company. At December 31, 1993, the Company's
investment in GP was approximately $11,753,000, of which $6,829,000 represents
the difference between the carrying amount of the investment and the amount of
the underlying equity in the net assets. Such amount is included in investments
and advances on the Company's consolidated balance sheet and is being amortized
on a straight-line basis over its estimated benefit period, 30 years. At
December 31, 1993, the Company owned 1,771,407 shares of GP with a total market
value of $6,864,000.

3. GTS Duratek, Inc.

On November 2, 1990, GTS Duratek, Inc. (Duratek), a majority owned subsidiary,
purchased General Technical Services, Inc. (GTS) from GP for a purchase price of
$7,500,000 in cash, 3,500,000 shares of Duratek's common stock and a $1,250,000
note. GTS, based in Columbia, Maryland, is a supplier of consulting and staff
augmentation services to utilities, Government agencies, and commercial
businesses. On December 31, 1992, Duratek issued 450,000 shares of Duratek
common stock to GPS in exchange for the $1,250,000 note and $150,000 of accrued
interest. In 1993, the Company distributed 667,134 shares of Duratek stock as
part of an Exchange Offer (See Note 9(a)). After the acquisition of GTS, the
retirement of the note and accrued interest and the Exchange Offer,
approximately 46% of the outstanding shares of Duratek's common stock is owned
by GPS (after the reorganization discussed in Note 2) and 20% of the shares are
owned by the Company. The Company, as a result of owning 92% of GPS, now
controls approximately 66% of Duratek. Duratek also provides environmental
services which includes the cleanup of water and other liquids containing
radioactive and/or hazardous (mixed waste) contaminants and in-furnace
vitrification for long-term stabilization of such waste.

In the fourth quarter of 1993, Duratek entered into a series of agreements which
resulted in the formation of a 50% owned company,Vitritek Environmental, Inc.
(Vitritek). The purpose of Vitritek is to develop technologies relating to the
vitrification of medical, hazardous and asbestos waste. In consideration for its
50% interest in Vitritek, Duratek contributed its option to acquire all rights,
title and interest in certain medical and hazardous waste vitrification
technologies. Duratek acquired this option for warrants to purchase 500,000
shares of Duratek's common stock for $4.00 per share and cash of $500,000
provided by the owners of the other 50% interest in Vitritek. The warrants
expire on September 30, 1997. In connection with these transactions, Duratek
agreed to sell to the two principal shareholders of the corporation which
contributed certain technologies relating to asbestos waste vitrification, and
who hold the other 50% interest in Vitritek, a total of 562,500 shares of
Duratek's common stock at $4.00 per share. Duratek received in consideration for
the shares, $1,500,000 in cash, and the two shareholders' interests in other
assets valued at $750,000.

4. Interferon Sciences, Inc.

Interferon Sciences, Inc. (ISI) is a 36% owned affiliate of the Company. It is
engaged in the manufacture and sale of ALFERONR N Injection, ISI's first product
commercially approved by the FDA for the treatment of recurring and refractory
external genital warts, and the research and development of other alpha
interferon based products for the treatment of viral diseases, cancers and
diseases of the immune system.

On July 12, 1993, the Company commenced an Exchange Offer for its Swiss Franc
denominated Bonds and its Dual Currency Bonds. (See Note 9(a)). As a result of
the inclusion of a portion of the Company's shares of Common Stock of ISI as
part of the consideration in the Exchange Offer, the Company's ownership in ISI
fell below 50%, and therefore, commencing during the third quarter of 1993, the
Company accounted for the results of ISI on the equity basis. The Company's
investment in ISI of approximately $6,167,000 is included in "Investments and
Advances" on the Consolidated Balance Sheet. At December 31, 1993, the Company
owned 6,985,000 shares of ISI, with a market value of $32,743,000. The Company's
share of ISI's loss included in Investment and other income, net is $857,000 in
1993.

approximately $9,588,000. In connection with the public offering, the Company
converted its outstanding advance to ISI at September 30, 1991 of $4,985,000
into $2,200,000 of common stock and contributed the remainder to capital in
excess of par value.

On May 30, 1991, the Company exchanged its ISI Class B common stock for an equal
number of shares of common stock. As a result, on that date, ISI ceased to be
included in the Company's consolidated Federal income tax return.

On April 12, 1991, ISI, the Company, The Purdue Frederick Company (Purdue
Frederick) and certain other companies (The Purdue Affiliates) entered into an
agreement (the Funding Agreement). Under the terms of the Funding Agreement, (i)
The Purdue Affiliates agreed to purchase $3,600,000 of ISI common stock at a
price of $4.10 per share (which occurred on June 14, 1991), (ii) on June 3,
1991, the Company exchanged $3,800,000 of the Company's common stock (with a
guaranteed value of $3,800,000 of proceeds for ISI from the sale of the
Company's common stock) for an equal value of ISI common stock and, (iii) Purdue
Frederick agreed to convert $1,975,000 of the prepayments for product made by
it, $850,000 in 1990, $425,000 in January 1991, and $700,000 in February 1991
into shares of ISI common stock at $4.10 per share (which occurred on June 14,
1991). Between August and October, 1991, ISI received $1,200,000 in net proceeds
from the sale of the Company's common stock and the Company paid ISI the
remaining $2,600,000 on October 31, 1991 (which represents the difference
between the guaranteed amount of $3,800,000 and the amount realized from the
sale of the ISI common stock which was $1,200,000).

7. Short-term borrowings (Continued)

(a) On April 8 and October 3, 1991, the Company entered into two amendments to
its November 1, 1989, $15,000,000 Revolving Credit and Term Loan Agreement (the
Loan Agreement). Under the terms of the amendments, the outstanding balance of
$10,346,000 at October 3, 1991, was payable in nine equal quarterly installments
of $1,150,000 which commenced on March 31, 1992. The loan bore interest at a
rate equal to 1/2% in excess of the bank's prime rate. On September 9, 1992, the
Company amended the Loan Agreement. Under the terms of the amendment, the
outstanding balance at January 1, 1992 is payable in four quarterly installments
of $1,150,000, $2,308,000, $1,156,000 and $5,732,000, commencing September 30,
1992. In October 1992, the bank released the $5,000,000 in cash collateral,
which was used to reduce the loan balance and the last scheduled payment by
$5,000,000. The bank agreed to defer the December 31, 1992 payment of $2,308,000
to April 1993. The entire loan balance of $4,196,000 at December 31, 1992 was
classified as a current liability. In April 1993, the Company repaid the balance
of the loan. (See Note 7(b)).

(b) In April 1990, the Five Star Group, Inc., (Five Star) entered into a three
year line of credit arrangement with a bank. Five Star could borrow up to a
maximum of $17,000,000, subject to the level of its qualified accounts
receivable and inventory, at an interest rate of 3/4% in excess of the prime
rate, subject to reduction, based upon certain financial criteria. The line of
credit was secured by substantially all the intangible and tangible property of
Five Star. As part of the agreement, the Company could borrow up to a maximum of
$7,000,000 from Five Star. As of December 31, 1992, $13,506,000 was borrowed by
Five Star.

In April 1993, Five Star and MXL Industries, Inc. ("MXL") entered into a
revolving credit and term loan agreement (the "Five Star Loan Agreement" and
"MXL Loan Agreement"). The Five Star Loan Agreement, which replaced the above
agreement, provided for a $20,000,000 revolving credit facility (the "Five Star
Revolving Credit Facility") and a $5,000,000 term loan (the "Five Star Term
Loan"). The Five Star Revolving Credit Facility is a three year committed
facility which allows Five Star to borrow amounts equal to 40% of Eligible
Inventory (as defined) and 75% of Eligible Receivables (as defined) at an
interest rate of 1% in excess of the prime rate. At December 31, 1993, the
interest rate was 7%. As of December 31 1993, $11,732,000 was borrowed under the
Five Star Revolving Credit Facility and Five Star had no additional
availability.

7. Short-term borrowings (Continued)

The Five Star Term Loan is repayable in 10 quarterly payments of approximately
$417,000 which commenced October 31, 1993, and a final payment of approximately
$830,000 on April 30, 1996. The Five Star Term Loan bears interest at 1 % in
excess of the prime rate, and was 7 3/8 % at December 31, 1993. The Five Star
Revolving Credit Agreement and the Five Star Term Loan are secured by all of the
assets of Five Star and 1,359,375 shares of common stock of ISI and 1,062,500
shares of common stock of GP, which were contributed to Five Star in connection
with the forgoing transactions. At December 31, 1993, $4,583,000 was outstanding
under the Five Star Term Loan.

The MXL Loan Areement provides for a $1,500,000 revolving credit facility (the
"MXL Revolving Credit Facility") and a $4,500,000 term loan (The "MXL Term
Loan"). The MXL Revolving Credit Facility is a three year committed facility
which allows MXL to borrow amounts equal to 25% of Eligible Inventory (as
defined) and 80% of Eligible Receivables (as defined) at an interest rate of 1%
in excess of the prime rate. At December 31, 1993, the interest rate was 7%. As
of December 31, 1993, there were no borrowings under the MXL Revolving Credit
Facility and the balance of the MXL Term Loan was $4,125,000. The MXL Term Loan
is repayable in 10 quarterly payments of approximately $375,000, which commenced
on October 31, 1993 with a final payment of $750,000 on April 30, 1996. The MXL
Term Loan bears interest at 1 3/8 % in excess of the prime rate, and was 7 3/8%
at December 31, 1993. The facilities are secured by all of the assets (other
than certain equipment) of MXL and by 815,625 shares of common stock of ISI
and 637,500 shares of common stock of GP, which were contributed to MXL in
connection with the forgoing transactions.

The Five Star Revolving Credit Facility and Five Star Term Loan and the MXL
Revolving Credit Agreement and MXL Term Loan are guaranteed by the Company. The
Agreements, among other things, limit the amount that Five Star and MXL may
borrow from other sources,the amount and nature of certain expenditures,
acquisitions and sales of assets, and the amount that Five Star and MXL can loan
or dividend to the Company. The agreements have several covenants, including
provisions regarding working capital, tangible net worth, leverage and cash flow
ratios.

7. Short-term borrowings (Continued)

(c) On October 3, 1991, GPS entered into an Amended and Restated Revolving
Credit and Term Loan and Security Agreement (the Agreement) with two banks. The
Agreement provided for a Term Loan of $5,000,000 and additional Revolving Credit
borrowings of up to $5,000,000. Borrowings under the Agreement were provided
equally by the participating banks, secured by accounts receivable, and bore
interest at rates set by such banks under options provided for in the Agreement.
Such Agreement, among other things, limited the amount that GPS may borrow from
other sources and the amount and nature of certain expenditures and required GPS
to maintain tangible net worth, working capital, cash flow, and debt ratios, as
defined in the Agreement. Term Loan borrowings were due in quarterly
installments which commenced December 31, 1991 and were to end on September 30,
1994.

On June 30, 1993, GPS replaced the above agreement with a new three year
$10,000,000 credit facility. The credit facility is secured by the accounts
receivable and fixed assets of GPS. The initial $5,000,000 of the credit
facility is fixed at an interest rate of 7.98% and the second $5,000,000 of the
credit facility bears interest at a rate equal to 1.25% in excess of the bank's
prime rate. At December 31, 1993, $5,650,000 was borrowed under the credit
facility.

(d) In August 1991, Eastern Electronics Manufacturing Corporation (Eastern)
assigned the remaining balance on its line of credit with a bank to a finance
company, with whom Eastern entered into a Security Agreement. Under the terms of
the Agreement, Eastern can borrow up to 80% of the net amount of eligible and
outstanding accounts receivable, as defined, at an interest rate of 5 1/2% over
the prime rate of interest (11.5% at December 31, 1993). At December 31, 1993,

(e)    On February 9, 1993, Duratek entered into a $7,000,000 Revolving Line of
Credit (the Line) and a $400,000 Loans to Facility (the Facility) for fixed
asset purchases with a commercial bank. On June 11, 1993, the Line was
increased to $7,750,000 and the Facility was increased to $750,000. Term Loans
under the Facility will be due over a 36 month period from the date of issue
and bear interest at the bank's prime rate plus 1 %. The Facility is secured
by the specific fixed assets financed under the Facility. The Line bears
interest at the bank's prime interest rate plus 1% and is secured by the
accounts receivable, inventory and property, plant and equipment of Duratek.
The Line requires Duratek to meet certain covenants concerning, among other
things, minimum tangible net worth, total liabilities to tangible net worth,
and profitability. It also contains limitations with respect to dividends or
other distributions to stockholders, mergers, acquisitions, and research and
development expenses. Short-term borrowings during 1992 were under an
agreement similar to the current agreement described above. At December 31,
1993, borrowings were $3,110,000 under the Line and $500,000 is outstanding
under the Facility.

(f)    In December 1992, the Company repurchased SFr. 1,264,000 of its
outstanding Swiss Bonds for a $466,000 Note, which bore interest at 1/2% per
month, due February 24, 1993. The Note was secured by 250,000 shares of the
Company's common stock. The principal amount of the Note could be reduced by
the proceeds from the sale of the common stock by the Company. At December 31,
1992, the balance of the Note, reduced for the proceeds from the sale of the
Company's common stock, was $183,000. The balance was repaid in February 1993.

1,125,000 of the 5 3/4% Bonds due May 9, 1995, SFr. 2,765,000 of the 5 5/8% 
Bonds due March 18, 1996, SFr. 16,806,000 of the 8% Bonds due March 1, 1995 and
$882,000 of the 7% Bonds due March 18, 1996. Under the terms of the Offer,
which included all unpaid accrued interest thereon, the Company issued the
following amounts of consideration to the exchanging bondholders a) 1,385,586
shares of Common Stock, valued at $5,582,000, b) 667,134 shares of ISI Common
Stock, valued at $2,536,000, c) 667,134 shares of Duratek Common Stock, valued
at $2,536,000, d) $3,340,080 principal amount of New 5% Bonds which will be
convertible into 767,833 shares of the Common Stock, and e) $1,099,368 in
cash. The Company recorded an original issue discount on the New 5% Bonds of
10%. At December 31, 1993, $2,536,000 of the New 5% Bonds were outstanding.

9. Long-term debt (Contiuned)

(b)    On December 20, 1989, in exchange for Swiss Francs (SFr.) 32,420,000
($20,318,000) of its 6% Convertible Swiss Bonds due March 7, 1995, SFr.
26,335,000 ($16,515,000) of its 5.75% Convertible Swiss Bonds due May 9, 1995,
and SFr. 26,685,000 ($16,734,000) of its 5.625% Convertible Swiss Bonds due
March 18, 1996, (collectively, the Old Bonds), each in the principal amount of
SFr. 5,000, plus all unpaid accrued interest thereon, the Company issued: (a)
SFr. 51,264,000 ($32,140,000) of its 8% Swiss Bonds due March 1, 1995, each in
the principal amount of SFr. 3,000, (the New Bonds) of which SFr. 7,401,000
are currently outstanding, (b) 17,088 Reset Warrants, each of which entitles
the holder to purchase 75 shares of the Company's common stock, at a price
determined by formula, exercisable until March 1, 1995, (c) 17,088 Common
Stock Warrants, each of which entitles the holder to acquire without further
consideration shares of the Company's common stock with a market value of SFr.
250, exercisable until March 1, 1995, and (d) SFr. 750 in cash.

       The Company recorded an original issue discount on the New Bonds of
40%, based upon exchange values estimated by the Swiss exchange agent.
Expenses of the exchange offer totaled $2,116,000. The discount and the
offering expenses, which have been deferred, are being amortized over the term
of the New Bonds.

(c)    On March 7, 1985, the Company issued, pursuant to a Swiss Public Bond
Issue Agreement, 6% Convertible Bonds due March 7, 1995 representing an
aggregate principal amount of SFr. 60,000,000, of which SFr. 8,635,000 are
currently outstanding (see (a) and (b) above). The outstanding bonds are
convertible into 148,522 shares of the Company's common stock at any time
prior to February 10, 1995 at a conversion price of approximately $39.15 per
share based on an exchange rate of SFr 1.485 per U.S. $1.00. In addition, on
May 9, 1985, the Company issued, pursuant to a second Swiss Public Bond Issue
Agreement, 5.75% Convertible Bonds due May 9, 1995, representing an aggregate
principal amount of SFr. 50,000,000, of which SFr. 3,520,000 are currently
outstanding (see (a) and (b) above). These outstanding bonds are convertible
into 75,328 shares of the Company's common stock at a conversion price of
$31.47 per share based on an exchange rate of SFr 1.485 per U.S. $1.00 at any
time prior to April 22, 1995. Expenses of both Swiss Public Bond Issues
totaled approximately $1,793,000 and at December 31, 1993 and 1992, the
unamortized balances of such expenses were $30,000 and $91,000, respectively.

(d)    On March 18, 1986, the Company issued, pursuant to a third Swiss Public
Bond Issue Agreement, 5.625% Convertible Bonds payable in 1996, representing
an aggregate principal amount of SFr. 50,000,000, of which SFr. 4,735,000 are
currently outstanding (see (a) and (b) above). Additionally, the Company
issued 7% Dual Currency Convertible Bonds, payable in 1996, representing an
aggregate principal amount of SFr. 25,000,000, but payable at maturity at the
fixed amount of $15,000,000. The outstanding Bonds are convertible into
218,800 shares of the Company's common stock at any time prior to March 8,
1996 at a conversion price of $34.71 per share based on an exchange rate of
SFr 1.485 per U.S. $1.00. Under certain circumstances, the Company may redeem
all of the Bonds (but not a part only) at a redemption price equal to par
value. Expenses related to the issuance of the Bonds totaled approximately
$1,660,000 and at December 31, 1993 and 1992, the unamortized balances of such
expenses were $61,000 and $132,000, respectively. The Dual Currency Bonds were
issued as part of the Company's overall financing strategy, without any intent
to either speculate in foreign exchange or to hedge any existing foreign
currency exposure. It is the Company's policy to record periodic interest
expense on the Dual Currency Bonds at the then current exchange rate. At
December 31, 1993 and 1992, based on year end exchange rates, the effective
rates of interest would be approximately 8%. At December 31, 1993, the
effective rate of interest of approximately 8% would result in an additional
$33,000 of interest expense per year, through March 1996.

On August 10, 1990, the Company completed an Exchange Offer pursuant to which
it received $4,659,000 of its 7% Dual Currency Convertible Bonds due March 18,
1996 (Bonds). In exchange, the Company issued 540,444 shares of its Common
Stock and warrants to purchase 465,900 shares of the Common Stock, par value
$.01 per share, of ISI, currently the Company's 36% owned affiliate,
exercisable at a price of $6.88 per share until August 16, 1992. The Exchange
Offer was completed on August 10, 1990 and the Company recorded an
extraordinary gain of $1,477,000 on the early extinguishment of the Bonds.
During February 1992, ISI called the warrants, resulting in net proceeds to
ISI of $2,956,000 from the issuance of 432,600 shares of ISI common stock upon
exercise of the warrants.

In addition to the bonds exchanged (see (a) and (b) above), during 1993, 1992
and 1991 the Company repurchased a portion of each of the Swiss Public Bond
Issues as well as Dual Currency Convertible Bonds. Extraordinary gains from
the early extinguishment of the Bonds in all such transactions amounted to
$1,819,000 (net of income taxes), $1,662,000 and $2,037,000, respectively.

9. Long-term debt (Continued)

(e)    During the third quarter of 1987, the Company issued $12,500,000 of
Subordinated Debentures (Debentures) which mature in 1997. Each $100 principal
amount Debenture was sold with warrants to purchase four shares of the
Company's common stock at a price of $18.50 per share. Expenses of the
offering amounted to approximately $1,908,000 and as of December 31, 1993 and
1992, the unamortized balances of such expenses were $432,000 and $550,000. In
connection with the terms of the Debentures, the Company is subject to certain
covenants which limit the amount that may be used for the payment of dividends
and for the purchase of the Company's outstanding equity securities (common or
Class B). In September 1990, under the terms of an Indenture, the Debentures
became exchangeable for the Company's Common Stock, for the remaining term of
the Debentures, at a price of approximately $5.00 per share. In 1993 and 1992,
$82,000 and $179,000, respectively, of Debentures were converted into 16,579
and 35,933 shares, respectively, of the Company's Common Stock. At December
31, 1993, the Debentures are convertible into approximately 1,374,000 shares
of the Company's Common Stock.

(f)    In March 1987, the Company and Ryder International Corporation (Ryder)
agreed to a settlement of litigation relating to the Company's Caridex/R/
system. Under the terms of the settlement agreement, the Company agreed to pay
Ryder (i) $1,000,000 in cash; (ii) $2,000,000 in common stock of the Company
(133,333 shares, valued at $2,000,000 were issued from treasury stock during
1987, and subsequently repurchased for $2,000,000 during 1988); and (iii)
$300,000 per year (in cash or common stock of the Company) for a ten year
period commencing January 15, 1988, the present value of which is discounted
at 10%, and included in long-term debt.

(g)    In May 1987, the Company and George K. Burke, Sr. and Concetta J. Burke
(the Burkes) settled a lawsuit asserting various claims for relief against the
Company with respect to several agreements concerning the marketing and
development of the EPIC/R/ system of intravenous devices, which the Company had
discontinued in December 1983. As a result of the settlement the Burkes
received $500,000 in cash upon execution of the settlement agreement and
received $250,000 a year (in cash or common stock of the Company) for a five
year period commencing in May 1988. In 1987, the Company recorded an
additional loss from this discontinued operation totaling $1,500,000,
representing the present value of the amounts due the Burkes plus the costs
relating to the litigation and settlement. The final payment was made in the
common stock of the Company in 1992.

9. Long-term debt (Continued)

(h)    During May 1983, ISI, a currently 36% controlled affiliate of the
Company, completed the sale of a 9.6% $1,450,000 Industrial Revenue Bond to
the New Jersey Economic Development Authority. The net proceeds were used to
pay for laboratory construction and equipment. The terms of the bond indenture
call for annual principal installments of $195,000 through 1993.

(i)    In March 1990, ISI borrowed $4,200,000 from a subsidiary of a bank at
an effective interest rate of 12.4% principally for the expansion of its
manufacturing facility. The loan calls for monthly payments of $41,500 for
months 1 to 24, which is comprised of interest only, and $139,500 (principal
and interest) for months 25 to 60. The loan is secured by certain equipment of
ISI and is guaranteed by the Company.

(j)    In December 1991, ISI issued a $459,000 note to Purdue Pharma L.P., an
affiliate of The Purdue Frederick Company, its marketing partner. The note
bears interest at 7.5% per annum, and required payment of interest and
principal on December 31, 1993, which was subsequently extended to April 27,
1994. As a result of the Exchange Offer (See (a)), ISI is currently accounted
for on the equity basis.

Aggregate annual maturities of long-term debt outstanding at December 31, 1993
for each of the next five years are as follows (in thousands):

10. Investment in finance subsidiaries (Continued)

Through these subsidiaries, GPS has entered into long-term agreements with two
domestic utilities to provide nuclear power plant simulator training services
along with the attendant nuclear power plant training simulators and related
training equipment. Under the provisions of the agreements, the subsidiaries
obtained non-recourse long-term financing from a bank to finance the purchase
of the simulators and training equipment. The agreements provide that the
subsidiaries are compensated, in part, for use of the simulators on
essentially a lease financing basis.

The agreements provide that the payments by the utilities will enable the
subsidiaries to recover the cost of the simulators plus interest at floating
rates which range from prime to 115% of prime, as well as the cost of
simulator replacement parts, taxes, and insurance. Such amounts will be
sufficient to fully service the related long-term debt discussed below. All
training services are performed by GPS personnel and are billed at established
hourly rates. Revenues for these services are recognized by GPS.

Under the agreements, the utilities have options to purchase the simulators
and other training equipment at the end of the loan terms.

Non-recourse long-term debt relating to the simulators consists of the
following (in thousands):

the loans.

The loans are secured by the equipment and all rights under the agreements
with the utilities. Under these agreements, GPS has agreed to guarantee the
service performance with the utilities but has not guaranteed the obligations
of its subsidiaries under the loan agreements. GPS has also agreed to maintain
a minimum debt to equity ratio, a minimum tangible net worth and a minimum
working capital, as defined.

11. Common stock issued subject to repurchase obligation

During the fourth quarter of 1993, the Company entered into several privately
negotiated agreements (the Agreements), pursuant to which it reacquired
previously outstanding Swiss Bonds in exchange for newly issued common stock.
In addition to common stock, the Company issued to the exchanging bondholder
in each transaction a non-negotiable, non interest bearing promissory note
(the Note) in a principal amount equal to the market value of the common stock
issued in the exchange. The recipient in each transaction obtained the rights,
exercisable within approximately a one year period from the date of the
Agreement, to sell, retain, or return to the Company the common stock
received, in whole or in part. Net proceeds of any sales of common stock by
the recipient during the period reduces the amount due under the Note, and
sales of common stock for net proceeds equal to or in excess of the principal
amount of the Note would cause the Note to be deemed as paid in full. Any
excess proceeds of sale of the stock over the principal amount of the Note are
retained by the stockholder.

11. Common stock issued subject to repurchase obligation (Continued)

The Company has accounted for the issuance of the common stock as permanent
equity to the extent of the proceeds of subsequent sales of stock by the
recipients, and as temporary equity for the balance of the market value of the
common stock issued. The Notes serve as a guarantee of the amounts which may
be refundable to the recipients of the common stock under the Agreement. The
Company's maximum repurchase or refund obligation under these Agreements as of
December 31, 1993 aggregated $4,242,000.

13. Disposal of business

      On April 8, 1991, the Company transferred substantially all the assets of
its National Patent Medical Division to a new partnership, National Patent
Medical Partnership, L.P. (NPM). In return, the Company received a 49%
interest in the partnership, $7,200,000 in cash and a $1,800,000 note at the
prime rate of interest plus 1/2%. The note is due in two equal installments in
1996 and 1997. In addition, the new partnership repaid $4,000,000 of short-
term borrowings attributable to the National Patent Medical Division. The
Company did not recognize any gain or loss as a result of this transaction.
NPM is involved in the manufacturing and distribution of first-aid products,
surgical dressings and other disposable hospital products. The financial
position and results of operations of NPM are included in the consolidated
accounts of the Company for all periods presented through April 8, 1991, the
date that the Company's ownership of NPM fell below 50%. Since then, the
accounts of NPM have not been consolidated with those of the Company. NPM's
net sales and operating loss through April 8, 1991 were $11,129,000 and
$(81,000), respectively. In November 1992, NPM Healthcare Products, Inc.
(NPMH), a successor to NPM, completed an initial public offering. As a result
of the public offering, the Company received approximately $4,500,000 in net
proceeds, which approximated the carrying value of the shares sold.

The Company has accounted for its investment in NPMH on the equity basis for
the period from April 9, 1991, when its equity in NPMH fell below 50%, to
December 31, 1991, and for the period from January 1, 1992 to October 1992,
when its equity fell to approximately 14% as a result of the public offering.
The Company's share in the net income (loss) of NPMH for the periods ended
December 31, 1991 and October 31, 1992, amounted to $(805,000) and $35,000,
respectively, after amortization of the underlying goodwill. At December 31,
1993, the Company's investment in NPMH was $3,914,000. In 1994, NPMH changed
its name to American White Cross, Inc.

14. Employee benefit plans

The Company had a Defined Benefit Pension Plan (the Plan) for employees of
certain divisions and subsidiaries. Benefits were based primarily on years of
service and a fixed rate of benefits per year of service. Contributions were
intended to provide not only for benefits attributed to service to date but
also for those expected to be earned in the future.

Effective December 31, 1991, the Plan benefits were frozen. Accrued vested
benefits will be paid to terminated participants in the form of a lump sum
distribution in cases where the accrued vested benefit is less than $3,500.
Terminated participants can elect a lump sum distribution if the accrued
vested benefit is greater than $3,500 but less than $7,500.

In the event that the accrued vested benefit exceeds the $7,500 payable limit
as outlined in the Plan, payment will be deferred until a terminated vested
participant reaches age 65 or elects early retirement at an earlier date, at
age 60 or later. The pension expense amounted to $377,000, $23,000 and
$552,000, for 1993, 1992 and 1991, respectively.

The following table sets forth the funded status of the plan and the amount
recognized in the Company's Consolidated Balance Sheets (in thousands):

14. Employee benefit plans (Continued)

The Company's assumptions used as of December 31, 1993, 1992, and 1991 in
determining the pension cost and pension cost liability shown above were as
follows:
                                                             Percent

Effective March 1, 1992, the Company adopted the 1992 401(K) Savings Plan (the
Savings Plan). Effective December 31, 1991, the Plan participants would no
longer accrue benefits under the Defined Benefit Pension Plan, but became
eligible to participate in the Company's Savings Plan.

The Company's Savings Plan is for employees who have completed one year of
service; however, past vesting service credit was recognized for employees who
participated in the Savings Plan at the date of initial enrollment, March 1,
1992.

The Savings Plan permits pre-tax contributions to the Savings Plan by
participants pursuant to Section 401(K) of the Internal Revenue Code of 2% to
6% of base compensation. The Company matches 40% of the participants' eligible
contributions based on a formula set forth in the Savings Plan. Participants
are fully vested in their contributions and may withdraw such contributions at
time of employment termination, or at age 59 or earlier in the event of
financial hardship. Amounts otherwise are paid at retirement or in the event
of death or disability. Employer contributions vest at a rate of 20% per year.

The Savings Plan is administered by a trustee appointed by the Board of
Directors of the Company and all contributions are held by the trustee and
invested at the participants' direction in various mutual funds. The expense
associated with the Savings Plan was $236,000 and $214,000 in 1993 and 1992,
respectively. During the first quarter of 1993, the Company adopted Statement
of Financial Accounting Standard No. 106 (SFAS No. 106), "Employers'
Accounting for Post Retirement Benefits Other Than Pensions". This statement
requires that the expected cost of post retirement benefits be fully accrued
by the first date of full benefit eligibility, rather then expensing the
benefit when payment is made. As the Company generally does not provide post
retirement benefits, other than pension, the new statement did not have any
material effect on the Company's financial condition or results of
operations.

</TABLE> 

In 1991, despite the Company's $1,157,000 income before income taxes, as well
as its $2,037,000 gain from extraordinary item, no Federal income tax expense
was recognized. This is due principally to significant permanent differences
between financial and tax reporting of 1991 transactions, including the
elimination for tax purposes of the $18,844,000 gain on the sale of GP stock
net of a gain recognized only for tax purposes upon ISI ceasing to be a member
of the Company's consolidated Federal income tax return group on May 31, 1991.
The income tax expense for 1991 of $549,000 represents state and local income
taxes.

In 1992, the Company's loss before income taxes exceeded its gains from
extraordinary items; therefore, no income tax expense applicable to such
extraordinary gains was recognized. The income tax expense for 1992 of
$427,000 represents state and local income taxes.

In 1993, the Company recorded an income tax benefit of $1,043,000, of which
$973,000 relates to Federal income taxes, in continuing operations as a result
of the income tax expense allocated to the extraordinary gain recognized on
the early extinguishment of debt under the provisions of FASB No. 109.

                                     62
<PAGE>
 
As of December 31, 1993, the Company has approximately $22,520,000 of
consolidated net operating loss carryovers for Federal income tax return
purposes, which expire beginning in the years 2002 through 2008. In addition,
the Company has approximately $2,784,000 of available credit carryovers.

Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS No. 109).
This statement requires that deferred income taxes be recorded following the
liability method of accounting and adjusted periodically when income tax rates
change. Adoption of the new Statement did not have a material effect on the
Company's financial condition or results of operations since the Company does
not carry any deferred tax accounts on its balance sheet.

A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax asset will not be realized. The Company has
determined, based on the Company's recent history of annual net losses, that a
full valuation allowance is appropriate.

The Company has, as of December 31, 1993, deferred tax assets of approximately
$19,267,000, deferred tax liabilities of approximately $5,909,000 and a
valuation allowance of approximately $13,358,000.

December 1987, was extended to December 1997.

Class B capital stock aggregating 1,550,000 shares at December 31, 1993, 1992,
and 1991 were reserved for issuance to these same two officers.

The holders of common stock are entitled to one vote per share and the holders
of Class B capital stock are entitled to ten votes per share on all matters
without distinction between classes, except when approval of a majority of each
class is required by statute. The Class B capital stock is convertible at any
time, at the option of the holders of such stock, into shares of common stock on
a share-for-share basis. Common shares reserved for issuance at December 31,
1993, 1992, and 1991 include 1,800,000 shares in connection with Class B shares.

At December 31, 1993, 1992, and 1991, shares reserved for issuance were
primarily related to shares reserved for options, warrants and the conversion of
long-term debt.

Identifiable assets by industry segment are those assets that are used in the
Company's operations in each segment. Corporate and other assets are principally
cash and cash equivalents, marketable securities and un-allocated intangibles.

18. Fair value of financial instruments

The carrying value of financial instruments including cash, short-term
investments, accounts receivable,restricted cash, accounts payable and short-
term borrowings approximate estimated market values because of short maturities
and interest rates that approximate current rates.

The carrying values of investments, other than those accounted for on the equity
basis, approximate fair values based upon quoted market prices. The investments
for which there is no quoted market price are not significant.

The estimated fair value for the Company's major long-term debt components are
as follows (in thousands):

Limitations. Fair value estimates are made at a specific point in time, based on
relevant market information and information about the financial instrument.
These estimates are subjective in nature and involve uncertainties and matters
of significant judgement and therefore cannot be determined with precision.
Changes in assumptions could significantly affect the estimates.

19. Commitments and contingencies

The Company has several noncancellable leases which cover real property,
machinery and equipment and certain manufacturing facilities. Such leases expire
at various dates with, in some cases, options to extend their terms.

Several of the leases contain provisions for rent escalation based primarily on
increases in real estate taxes and operating costs incurred by the lessor. Rent
expense for real and personal property was approximately $7,792,000, $7,806,000
and $4,691,000 for 1993, 1992 and 1991, respectively.

19.  Commitments and contingencies (Continued)

In February 1986, Duratek completed its initial public offering of common
stock. In connection with Duratek's public offering, the Company issued to
certain officers of Duratek and the Company 358,609 options for the purchase
of Duratek common stock owned by the Company at a price equal to the greater
of (a) $1.75 per share or (b) the net book value per share of Duratek's common
stock as of the end of the most recently completed fiscal quarter which ends
not less than 60 days before the date of exercise of such option. In 1991, an
additional 270,000 options for the purchase of Duratek common stock owned by
the Company at a price of $1.90 per share were issued to certain employees and
officers of the Company. Through December 31, 1993, 28,600 options under the
plan were exercised, 57,500 were cancelled, and at December 31, 1993, 369,750
options are currently exercisable. At December 31, 1993, the Company owned
approximately 66% of Duratek.

The Company is party to several lawsuits and claims incidental to its
business, including claims regarding environmental matters, one of which is in
the early stages of investigation. It is not possible at the present time to
estimate the ultimate legal and financial liability, if any, of the Company in
respect to such litigation and claims; however, management believes that the
ultimate liability, if any, will not have a material adverse effect on the
Company's Consolidated Financial Statements.

20. Subsequent event

On January 13, 1994, GP signed a Letter of Intent with GPS and the Company to
acquire substantially all of the operating assets of GPS and certain of its
subsidiaries. The Company currently owns approximately 92% of the outstanding
common stock of GPS and approximately 28% of the outstanding common stock of
GP. On March 28, 1994, the Board of Directors of both GP and GPS approved the
transaction. The parties are currently negotiating the terms of a definitive
agreement and the transaction is anticipated to close as soon as practicable
in the second half of 1994, if all necessary approvals are obtained and
conditions satisfied.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)


20.  Subsequent event (Continued)

The purchase price has a current present value of approximately $36 million
based on current market prices. The purchase price will be payable to GPS as
follows: $10 million cash; 3.5 million shares of GP common stock valued at
approximately $13,500,000 (based upon the price per share of GP common stock
prior to the announcement of the transaction which was $3.875); warrants to
acquire 1,000,000 shares of GP common stock at $6.00 per share valued at
approximately $1,300,000; warrants to acquire up to 475,644 additional shares
of GP common stock at $7 per share valued at approximately $500,000; a $15
million ten-year senior subordinated debenture valued at approximately
$10,700,000, accruing interest at 6% per annum, interest payable only for the
first five years, with 70% of principal payable in equal quarterly
installments during the remaining five years until maturity.

Portions of the cash and stock consideration of the purchase price will be (a)
used to repay outstanding bank debt of $5,650,000 (as of December 31, 1993)
and long-term debt of GPS of $8,809,000 (as of December 31, 1993) to be repaid
to the Company. In addition, $1.5 million of Debentures are held in escrow for
the benefit of GP in connection with certain indemnification obligations.

The transaction is contingent upon the occurrence of certain events,
including, without limitation, approval of the transaction by the stockholders
of both GPS and GP.

The Company anticipates that if the aforementioned transaction is consummated,
it will own approximately 52% of the outstanding common stock of GP, and if
the Company were to exercise all of its warrants, it will own approximately
58% of the outstanding common stock of GP.

The Company will account for this transaction as a purchase of GP. The Company
believes that any gain or loss to be recognized on this transaction would not
be significant, since the transaction (based upon the currently contemplated
assets to be sold), if consummated, is expected to be consummated at or near
the carrying value of the underlying assets.

Although an agreement in principle has been reached, there can be no assurance
that a definitive agreement will be successfully negotiated and signed, or
that the transaction will close as anticipated.

(1)  The above represents a note receivable due on July 9, 1997. Interest at 6%
     per annum is payable quarterly.

(2)  The above is a note receivable recorded on the balance sheet of Interferon
     Sciences, Inc. (ISI). As a result of the Company's interest in ISI falling
     below 50% in 1993, ISI is accounted for on the equity method, and
     accordingly the balance of $150,000 at December 31, 1993 is not included in
     the Company's financial statements. During 1993, $50,000 of the note
     receivable was repaid by the borrower.

(Continued)



          Note (c):    COMMITMENTS AND CONTINGENCIES

          The Company has several noncancellable leases which
cover real
          property and machinery and equipment.  Such leases
expire at
          various dates with, in some cases, options to extend
their terms.

          Minimum rentals under long-term operating leases are as
follows
          (in thousands):

</TABLE>



          Several of the leases contain provisions for rent
escalation
          based primarily on increases in real estate taxes and
operating
          costs incurred by the lessor.

          The Company is party to several lawsuits incidental to
its
          business.  It is not possible at the present time to
estimate the
          ultimate legal and financial liability, if any, of the
Company
          with respect to such litigation; however, management
believes
          that the ultimate liability, if any, will not have a
material
          adverse effect on the Company's Financial Statements.

          The Board of Directors and Stockholders
          National Patent Development Corporation


Under date of March 30, 1994, we reported on the consolidated balance sheet of
National Patent Development Corporation and subsidiaries as of December 31, 1993
and 1992, and the related consolidated statements of operations, changes in
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1993, as contained in the annual report on Form 10-K
for the year 1993. In connection with our audits of the aforementioned
consolidated financial statements, we also have audited the related financial
statement schedules as listed in the accompanying index. These financial
statement schedules are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statement schedules
based on our audits.

In our opinion, the related financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein.

      NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (Continued)

                                 (Unaudited)


3.   Subsequent event

     On April 7, 1994, General Physics Corporation (GP) entered into an
agreement with GPS Technologies, Inc. (GPS) and the Company to acquire
substantially all of the operating assets of GPS and certain of its
subsidiaries. The Company currently owns approximately 92% of the outstanding
common stock of GPS and approximately 28% of the outstanding common stock of
GP. GP agreed to pay GPS a purchase price with current present value of
approximately $36 million based on current market prices. The purchase price
will be payable to GPS as follows: $10 million in cash; 3.5 million shares of
GP common stock valued at approximately $13,500,000 (based upon the price per
share of GP common stock prior to the announcement of the transaction which
was $3.875); warrants to acquire 1,000,000 shares of GP common stock at $6.00
per share valued at approximately $1,300,000; warrants to acquire up to
475,644 additional shares of GP common stock at $7 per share valued at
approximately $500,000; and 6% Senior Subordinated Debentures due 2004 (the
"Debentures"), in the aggregate principal amount of $15,000,000, valued at
approximately $10,700,000. The values assigned to each component of
consideration were based upon discussions with the independent investment
banker to the Independent Committee of GP and the investment banker to GPS.
Portions of the cash and stock consideration of the purchase price will be (a)
used to repay outstanding bank debt of $5,650,000 and long-term debt of GPS of
$8,809,000 to be repaid to the Company and (b) held in escrow.

     The transaction is contingent upon the occurrence of certain events,
including, without limitation, the approval of the transaction by the
stockholders of GP and GPS. The transaction is anticipated to close as soon as
practicable in the second half of 1994, if all necessary approvals are
obtained and conditions satisfied. The Company anticipates that, if the
aforementioned transaction is consummated, it will own approximately 52% of
the outstanding common stock of GP, and if the Company were to exercise all of
its warrants, it would own approximately 58% of the outstanding common stock
of GP. The Company will account for this transaction as a purchase by the
Company of GP.

         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                          AND RESULTS OF OPERATIONS

                            RESULTS OF OPERATIONS

     The Company had a loss before income taxes and extraordinary item of
$(2,394,000) for the quarter ended March 31, 1994 compared to $(2,939,000) for
the quarter ended March 31, 1993. During the first quarter of 1994, the
Company realized net foreign currency transaction losses of $(897,000), as
compared to a gain of $670,000 for the first quarter of 1993 as a result of
the weakness of the U.S. dollar relative to the Swiss Franc and the Company's
decision not to hedge its Swiss currency obligations. At March 31, 1994, there
was an aggregate of SFr. 26,318,000 of Swiss denominated indebtedness
outstanding, of which SFr. 23,823,000 represents principal amount outstanding
and SFr. 2,495,000 represents interest accrued thereon. Foreign currency
valuation fluctuations may adversely affect the results of operations and
financial condition of the Company. In order to protect itself against
currency valuation fluctuations, the Company has at times swapped or hedged a
portion of its obligations denominated in Swiss Francs. At March 31, 1994, the
Company had not hedged its Swiss Franc obligations. If the value of the Swiss
Franc to the U.S. dollar increases, the Company will recognize transaction
losses on its Swiss Franc obligations. On March 31, 1994, the value of the
Swiss Franc to the U.S. dollar was 1.4120 to 1. There can be no assurance that
the Company will be able to swap or hedge obligations denominated in foreign
currencies at prices acceptable to the Company or at all. The Company will
continue to review this policy on a continuing basis.

     The foreign currency transaction loss was offset by reduced interest
expense due to a reduction in long-term debt, as well as improved operating
results within the Optical Plastics and Physical Science Groups. The Optical
Plastics Group achieved improved operating results due to increased sales and
gross margin percentages. The Physical Science Group achieved improved results
due to a favorable change in the mix of products and services provided to its
customers.

Sales
- -----

     For the quarter ended March 31, 1994, consolidated sales increased by
$268,000 to $45,232,000 from the $44,964,000 in the corresponding quarter of
1993. The increased sales were the result of increased sales within the
Distribution and Optical Plastics Groups, offset by reduced sales by the
Physical Sciences Group due to the end of a long-term staff augmentation
contract at GTS Duratek, Inc. (Durtek).




                                          8

Gross margin
- ------------

     Consolidated gross margin of $8,247,000, or 18%, for the quarter ended
March 31, 1994, increased by $2,054,000 compared to the consolidated gross
margin of $6,193,000, or 14%, for the quarter ended March 31, 1993. The
increased gross margin in 1994 was primarily the result of increased sales and
gross margin percentage achieved by the Optical Plastics Group, as well
increased gross margin achieved by the Physical Science Group due to the
higher gross margin generated by Duratek's Environmental Services business and
a more profitable mix of services generated by GPS Technologies, Inc.

Selling, general and administrative expenses
- --------------------------------------------

     For the three months ended March 31, 1994, selling, general and
administrative (SG&A) expenses were $8,198,000 compared to the $8,297,000
incurred in the first quarter of 1993. The decrease in SG&A for the first
quarter of 1994 was the result of ISI being accounted for on the equity method
since the third quarter of 1993, partially offset by increased costs incurred
by the Distribution, Optical Plastics and Physical Sciences Groups.

Interest expense
- ----------------

     For the three months ended March 31, 1994, interest expense was
$1,503,000 compared to $2,473,000 for the three months ended March 31, 1993.
The decreased interest expense for the quarter was the result of reduced long-
term debt.

Investment and other income, net
- --------------------------------

     Investment and other income, net of $(752,000) for the quarter ended
March 31, 1994, decreased by $2,660,000 as compared to $1,908,000 for the
first quarter of 1993. The reduced investment and other income was principally
due to the effect of the following two factors; $(897,000) and $670,000 of
foreign currency transaction gains (losses), for the quarters ended March 31,
1994 and 1993, respectively, and a loss of $(770,000) realized in the quarter
ended March 31, 1994, on the share of losses of 20% to 50% owned subsidiaries,
compared to $175,000 earned in the quarter ended March 31, 1993, as a result
of the results of Interferon Sciences, Inc. (ISI) being accounted for on the
equity basis since the third quarter of 1993. For the quarter ended March 31,
1994, the Company's share of ISI's loss was $845,000. In the quarter ended
March 31, 1993, ISI was included in the consolidated results of the Company
and its loss was therefore not reflected in Investment and other income, net.

                       LIQUIDITY AND CAPITAL RESOURCES

     The Company believes that it has sufficient cash, cash equivalents and
borrowing availability under existing and potential lines of credit to satisfy
its cash requirements until the first scheduled maturity of its Swiss Franc
denominated indebtedness on March 1, 1995. However, in order for the Company
to meet its long-term cash needs, which include the repayment of $13,518,000
of Swiss Franc denominated indebtedness scheduled to mature in 1995 and
$7,279,000 of Swiss Franc denominated indebtedness which is scheduled to
mature in 1996, the Company must obtain additional funds from among various
sources. The Company has historically reduced its long-term debt through the
issuance of equity securities in exchange for long-term debt. In addition to
its ability to issue equity securities, the Company believes that it has
sufficient marketable long-term investments, as well as the ability to obtain
additional funds from its operating subsidiaries and the potential to enter
into new credit arrangements. The Company reasonably believes that it will be
able to accomplish some or all of the above transactions in order to fund the
scheduled repayment of the Company's long-term Swiss debt in 1995.

     At March 31, 1994, the Company had cash and, cash equivalents totaling
$9,848,000. GPS Technologies, Inc. and GTS Duratek, Inc. had cash and, cash
equivalents of $392,000 at March 31, 1994. The minority interests of these two
companies are owned by the general public, and therefore the assets of these
subsidiaries have been dedicated to the operations of these companies and may
not be readily available for the general corporate purpose of the parent.

               QUALIFICATION RELATING TO FINANCIAL INFORMATION

                               March 31, 1994




     The financial information included herein is unaudited. In addition, the
financial information does not include all disclosures required under
generally accepted accounting principles because certain note information
included in the Company's Annual Report has been omitted; however, such
information reflects all adjustments (consisting solely of normal recurring
adjustments) which are, in the opinion of management, necessary for a fair
statement of the results for the interim periods. The results for the 1994
interim period are not necessarily indicative of results to be expected for
the entire year.

                                   PROXY STATEMENT
             
               The accompanying Proxy is solicited by and on behalf of the
          Board of Directors of National Patent Development Corporation, a
          Delaware corporation (the "Company"), for use only at the Annual
          Meeting of Stockholders to be held at The Brunswick Hilton, Three
          Tower Center Boulevard, East Brunswick, New Jersey on the 8th day
          of June, 1994 at 1:30 P.M., Eastern Standard Daylight Savings
          Time, and at any adjournments thereof. The approximate date on
          which this Proxy Statement and the accompanying Proxy were first
          given or sent to security holders was April 28, 1994. 
              
               Each Proxy executed and returned by a stockholder may be
          revoked at any time thereafter, by written notice to that effect
          to the Company, attention of the Secretary, prior to the Annual
          Meeting, or to the Chairman of, or the Inspectors of Election, in
          person, at the Annual Meeting, or by the execution and return of
          a later-dated Proxy, except as to any matter voted upon prior to
          such revocation. 
             
               The Proxies in the accompanying form will be voted in
          accordance with the specifications made and where no
          specifications are given, such Proxies will be voted FOR the six
          nominees for election as directors named herein, FOR the
          amendment to the Company's Restated Certificate of Incorporation
          to increase the total number of shares of common stock which the
          Company shall have authority to issue, and FOR the approval of
          the selection of KPMG Peat Marwick as auditors. In the discretion
          of the proxy holders, the Proxies will also be voted FOR or
          AGAINST such other matters as may properly come before the
          meeting. The management of the Company is not aware that any
          other matters are to be presented for action at the meeting.
          Although it is intended that the Proxies will be voted for the
          nominees named herein, the holders of the Proxies reserve
          discretion to cast votes for individuals other than such nominees
          in the event of the unavailability of any such nominee.  The
          Company has no reason to believe that any of the nominees will
          become unavailable for election. The Proxies may not be voted for
          a greater number of persons than the number of nominees named.
          The election of directors will be determined by a plurality of
          the votes of the shares of common stock, par value $.01 per share

          by proxy at the Annual Meeting and entitled to vote on the
          election of directors. A majority of the votes represented by the
          outstanding shares of Common Stock and a majority of the votes
          represented by the outstanding shares of Class B Stock, each
          voting separately as a class, is required to approve the proposal
          to amend the Restated Certificate of Incorporation to increase
          the total number of shares of Common Stock which the Company
          shall have authority to issue, while approval of the selection of
          auditors for the current year will require the affirmative vote
          of holders of Common Stock and Class B Stock representing a
          majority of the outstanding shares present in person or
          represented by proxy. Accordingly, in the case of shares that are
          present or represented at the Annual Meeting for quorum purposes,
          not voting such shares for a particular nominee for director,
          including by withholding authority on the Proxy, will not operate
          to prevent the election of such nominee if he or she otherwise
          receives affirmative votes; with respect to the approval of the
          Amendment to the Company's Restated Certificate of Incorporation,
          an abstention will operate to prevent approval of the item to the
          same extent as a vote against approval, and a broker "non-vote"
          (which results when a broker holding shares for a beneficial
          owner has not received timely voting instructions on certain
          matters from such beneficial owner) will effect the outcome of
          the vote the same as a negative vote with respect to the approval
          of the Amendment to the Company's Restated Certificate of
          Incorporation.
              
                                  VOTING SECURITIES
             
               The Board of Directors has fixed the close of business on
          April 15, 1994 as the record date for the determination of
          stockholders entitled to receive notice of and to vote at the
          Annual Meeting. The issued and outstanding stock of the Company
          on April 15, 1994 consisted of 20,310,706 shares of Common Stock,
          each entitled to one vote, and 250,000 shares of Class B Stock,
          each entitled to ten votes. A quorum of the stockholders is
          constituted by the presence, in person or by proxy, of holders of
          record of Common Stock and Class B Stock representing a majority
          of the number of votes entitled to be cast. The only difference
          in the rights of the holders of Common Stock and the rights of
          holders of Class B Stock is that the former class has one vote
          per share and the latter class has ten votes per share. The
          Class B Stock is convertible at any time into shares of Common
          Stock on a share for share basis at the option of the holders
          thereof. 
              
                           PRINCIPAL HOLDERS OF SECURITIES

               As of March 1, 1994, no person was known to the Company to

          which they currently have the right to purchase pursuant to the
          exercise of stock options. 

          (2)Percentage could increase up to approximately 88% if either
          individual exercised all of his stock options and the other
          individual did not exercise any. 

               Based upon the Common Stock and Class B Stock of the Company
          outstanding at March 1, 1994, Mr. Feldman and Mr. Pollak
          controlled approximately 13% of the voting power of all voting
          securities of the Company. This percentage for Mr. Feldman and
          Mr. Pollak would increase to approximately 51% if they exercised
          all the presently outstanding options to purchase shares of the
          Common Stock and Class B Stock of the Company held by them. 

               On March 26, 1986, Mr. Feldman and Mr. Pollak entered into
          an agreement (i) granting each other the right of first refusal
          over the sale or hypothecation of the Class B Stock and options
          to purchase Class B Stock now owned or subsequently acquired by
          each of them and (ii) in the event of the death of either of them
          granting the survivor a right of first refusal over the sale or
          hypothecation of the Class B Stock or options to acquire shares
          of Class B Stock held by the estate of the decedent. The
          aforesaid right of first refusal is for the duration of the life
          of the survivor of Mr. Feldman or Mr. Pollak.

          Board Compensation Committee Report on Executive Compensation

               During the year ended December 31, 1993, the Company did not
          have a Compensation Committee. Accordingly, the full Board of
          Directors is responsible for determining and implementing the
          compensation policies of the Company.          
             
               The executive compensation policies are designed to offer
          competitive compensation opportunities for all executives which are
          based on personal performance, individual initiative and
          achievement, and assist the Company in attracting and retaining
          qualified executives.          
              
             
               The Board also endorses the position that stock ownership by
          management and stock-based compensation arrangements are beneficial
          in aligning managements' and shareholders' interests in the
          enhancement of shareholder value and recommends to the Stock Option
          Committee the grant of stock options to executive officers whose
          performance has a significant effect on the success of the Company.
              
               Compensation paid to the Company's executive officers generally
          consists of the following elements: base salary, annual bonus and
          grant of stock options. The compensation for Mr. Pollak is
          determined on the same basis as that of Mr. Feldman, the Chief
          Executive Officer. The compensation for the other executive officers
          of the Company is determined by a consideration of each officer's
          initiative and contribution to overall corporate performance, the
          officer's managerial abilities and the performance in any special
          projects that the officer may have undertaken. Competitive base
          salaries that reflect the individual's level of responsibility are
          important elements of the Company's executive compensation
          philosophy. Subjective considerations of individual performance are
          considered by the Board in establishing annual bonuses and other
          incentive compensation.

               The Company has certain broad-based employee benefit plans in
          which all employees, including the named executives are permitted to
          participate on the same terms and conditions relating to eligibility
          and subject to the same limitations on amounts that may be
          contributed. In 1993, the Company also made a matching contribution
          to the 401(k) Savings Plan for those participants.

          Mr. Feldman's 1993 Compensation
             
               Mr. Feldman's compensation is determined principally by the
          terms of his employment agreement. As of January 1, 1989, the
          Company entered into an Employment Agreement (the "Agreement") with
          Mr. Feldman which provides that Mr. Feldman will serve as

          President and Chief Executive Officer of the Company for the period
          through December 31, 1994. See "Employment Contracts and Termination
          of Employment and Change in Control Arrangements." The Agreement was
          approved by a vote of the entire Board. The Agreement provides Mr.
          Feldman with annual compensation (a minimum base salary) of $300,000
          (subject to review by the Board of Directors). Mr. Feldman also
          received a cash bonus of $120,000 in 1993. Among the factors the
          Board considered in awarding Mr. Feldman a cash bonus, were Mr.
          Feldman's significant contribution to the Company's reduction of its
          long-term debt and improvement of the financial performance of
          certain operating units of the Company. In addition, in 1993 Mr.
          Feldman received compensation of $16,250 for serving as a Director
          and Chairman of the Executive Committee of General Physics
          Corporation, a public company, in which National Patent has an
          approximately 28% investment.

          Compensation Committee Interlocks and Insider Participation

               During the year ended December 31, 1993 the Company did not
          have a Compensation Committee and the entire Board of Directors made
          decisions on compensation of the Company's executives. Mr. Feldman,
          the Company's Chief Executive Officer and a director, Mr. Pollak,
          the Company's Executive Vice President and Treasurer and a director
          and Mr. Greenberg, the Company's Vice President and Chief Financial
          Officer and a director participated in Board executive compensation
          deliberations.

          Employment Contracts and Termination of Employment and Change in
          Control Arrangements

          Agreements with Messrs. Feldman and Pollak. As of January 1, 1989,
          the Company entered into the Agreements with its President and Chief
          Executive Officer, Jerome I. Feldman, and with its Executive Vice
          President and Treasurer, Martin M. Pollak (the "Employees").

               Pursuant to the Agreements, Mr. Feldman will serve as President
          and Chief Executive Officer of the Company and Mr. Pollak will serve
          as Executive Vice President and Treasurer of the Company for the
          period through December 31, 1994. The Agreements provide for each
          Employee to receive annual compensation (a minimum base salary) of
          $300,000 (subject to

                                          15
<PAGE>
 
          increase by the Board of Directors). The Agreements provide for the
          termination of employment upon the Employee's death, physical or
          mental disability or retirement. In addition, the Company may
          terminate the Employee's employment "for cause" (including a failure
          to perform required duties or the engaging in of gross misconduct)
          and each Employee may voluntarily terminate his employment for "Good
          Reason", which occurs if the Employee determines in good faith that
          due to a change in control of the Company he is not able to
          effectively discharge his duties. "Change in control" is defined to
          include (1) any "person" (other than the Employees or certain
          persons who may acquire securities of the Company from an Employee)
          acquiring the beneficial ownership of more than 30% of the Company's
          outstanding securities or (2) certain changes in the composition of
          the Board of Directors of the Company.

               Upon termination by the Company "for cause", all obligations of
          the Company under the Employee's Agreement terminates. Upon
          termination by the Company other than "for cause", disability, or
          retirement, or by the Employee for "Good Reason", such Employee is
          entitled to receive as severance pay an amount equal to his full
          base salary (which at the present time is a minimum of $300,000 for
          each of the Employees) at the rate then in effect, multiplied by the
          greater of (1) the number of years (including fractions thereof)
          remaining in the term of the employment, or (2) the number three. In
          addition, the Employee would receive an amount in cash equal to the
          aggregate spread between the exercise prices of all options held by
          the Employee under the Company's 1973 Non-Qualified Stock Option
          Plan and the higher of (x) the market value of the Common Stock, and
          (y) the highest price paid in connection with any change in control
          of the Company. Subject to certain conditions, the Company would
          also maintain for two years (or until the Employee's commencement of
          full-time employment with a new employer) certain insurance, health
          and disability plans in effect, or arrange for substantially similar
          benefits. The Agreements also contain non-competition and
          confidentiality provisions.

               PROPOSED AMENDMENTS TO THE CERTIFICATE OF INCORPORATION


          Increase in Authorized Shares

               The Board of Directors unanimously recommends that the
          stockholders adopt an amendment to the Company's Certificate of
          Incorporation which will increase the authorized shares of Common
          Stock, par value $.01 per share, from 30,000,000 shares to
          40,000,000 shares. On March 1, 1994, 20,295,388 of the 30,000,000
          shares of Common Stock presently authorized were outstanding and an
          aggregate of 9,710,257 shares were reserved for issuance.

               The Company's Board of Directors has unanimously recommended
          for approval by stockholders the proposal to amend the first
          sentence of Article Fourth of the Certificate of Incorporation as
          follows:

                    "FOURTH: The total number of shares of all classes of
               stock which the Corporation shall have authority to issue is
               fifty-two million eight hundred thousand (52,800,000) shares of
               which forty million (40,000,000) are to be Common Stock of the
               par value of one cent ($.01) per share (hereinafter called the
               "Common Stock"); of which two million eight hundred thousand
               (2,800,000) shares are to be Class B Capital Stock with a par
               value of one cent ($.01) per share (hereinafter called the
               "Class B Capital Stock"); and of which ten million (10,000,000)
               shares are to be Preferred Stock with a par value of one cent
               ($.01) per share (hereinafter called the "Preferred Stock"), to
               be issued in such series and with such terms and conditions as
               the Board of Directors may determine.

               The Board of Directors believes that it would be in the best
          interests of the Company to have additional shares of Common Stock
          available for issuance at its discretion and without the necessity
          for a special stockholders' meeting to enhance the

                                          17
<PAGE>
 
          Company's flexibility in connection with possible future actions,
          such as acquisitions, financings, investment opportunites, internal
          development, retirement of outstanding indebtedness, and other
          corporate purposes.
             
               If the amendment is approved by the stockholders as described
          below, the additional shares may be issued from time to time upon
          authorization of the Board of Directors without further
          authorization of the stockholders for such consideration as the
          Board of Directors may determine and as may be permitted by the laws
          of Delaware. The amendment is not being proposed as a means of
          preventing a change in control or takeover of the Company. However,
          the use of these shares for such a purpose is possible. For
          instance, shares of authorized but unissued or unreserved Common
          Stock could be issued in an effort to dilute the stock ownership and
          voting power of persons seeking to obtain control of the Company or
          could be issued to purchasers who would support the Board of
          Directors in opposing a takeover proposal. Such possibilities may
          have the effect of discouraging a challenge for control or making it
          less likely that such a challenge would take place. The unissued and
          unreserved shares of Common stock, Class B Capital Stock and
          Preferred Stock will still be available for issuance for any proper
          corporate purpose, as authorized from time to time by the Board of
          Directors without further approval by the stockholders of the
          Company. The additional shares of Common Stock will be identical to
          the currently authorized shares of Common Stock in all respects.
          Holders of such shares will not have preemptive rights to purchase
          any capital stock of the Company.
              
          Reasons for and Effect of Authorization
             
               The Board of Directors believes that the complexity of modern
          business financing requires greater flexibility in the Company's
          capital structure than now exists. For example, the Company has in
          the past issued Common Stock as consideration for the retirement of
          outstanding Swiss indebtedness and accrued and unpaid interest
          thereon, in order to strengthen the financial position of the
          Company. The Company may make similar offers in the future, on terms
          and conditions approved by the Board of Directors. If the amendment
          is approved by the stockholders, the Company expects that such
          transaction will in most cases not be subject to further approval of
          stockholders. The additional shares of Stock to be authorized by the
          proposed amendment would be available for issuance from time to time
          for any proper corporate purpose, including, as appropriate,
          acquisitions and public or private sales for cash as a means of
          obtaining capital for use in the Company's business, retirement of
          outstanding indebtedness, and other corporate purposes.
              
               It is not possible to state the actual effect of the
          authorization of the additional shares of stock upon the rights

                                          18
<PAGE>
 
          of holders of the Common Stock, however the effect of the additional
          shares of Common Stock might include dilution of the equity interest
          of the Common Stock.

                APPROVAL OF SELECTION OF KPMG PEAT MARWICK AS AUDITORS

               The Board of Directors has selected KPMG Peat Marwick to audit
          the accounts of the Company for the year ending December 31, 1994.
          KPMG Peat Marwick has no financial interest in the Company and
          neither it nor any member or employee of the firm has had any
          connection with the Company in the capacity of promoter,
          underwriter, voting trustee, director, officer or employee. KPMG
          Peat Marwick has audited the accounts of the Company since 1970. The
          Delaware General Corporation Law does not require the approval of
          the selection of auditors by the Company's stockholders, but in view
          of the importance of the financial statements to the stockholders,
          the Board of Directors deems it desirable that they pass upon its
          selection of auditors. In the event the stockholders disapprove the
          selection, the Board of Directors will consider the selection of
          other auditors. The Board of Directors recommends that you vote in
          favor of the above proposal in view of the familiarity of KPMG Peat
          Marwick with the Company's financial and other affairs acquired
          during its previous service as auditors for the Company.

               A representative of KPMG Peat Marwick is expected to be present
          at the Annual Meeting, with the opportunity to make a statement if
          he desires to do so, and is expected to be available to respond to
          appropriate questions.

                                STOCKHOLDER PROPOSALS

               Stockholders may present proposals for inclusion in the
          Company's 1995 proxy statement provided they are received by the
          Company no later than January 13, 1995, and are otherwise in
          compliance with applicable Securities and Exchange Commission
          regulations.
                                       GENERAL

               So far as is now known, there is no business other than that
          described above to be presented for action by the stockholders at
          the meeting, but it is intended that the proxies will be voted upon
          any other matters and proposals that may legally come before the
          meeting and any adjournments thereof in accordance with the
          discretion of the persons named therein.

                                 COST OF SOLICITATION

               The cost of solicitation of proxies will be borne by the
          Company. It is expected that the solicitations will be made
          primarily by mail, but regular employees or representatives of

                                          19

          the Company may also solicit proxies by telephone or telegraph and
          in person, and arrange for brokerage houses and other custodians,
          nominees and fiduciaries to send proxy material to their principals
          at the expense of the Company.

   To _________________

        National Patent Development  Corporation (the "Company") has offered
   (the "Offer")  to exchange (i)  common stock,  par value  $.01 per  share
   (the "Common Stock"), of  the Company with  a market value of SFr.  1,000
   for each  SFr. 1,000  in principal amount  of the Old  Swiss Franc  Bonds
   validly tendered  and not  withdrawn prior  to the  Expiration Date,  and
   (ii) Common  Stock with a market value of US $1,000 for each US $1,000 in
   principal amount of the  Old U.S. Dollar Bonds  validly tendered and  not
   withdrawn prior to the Expiration Date.  A  summary of the procedures for
   the Offer  is described  below and  is fully  set forth  in the  Offering
   Circular  dated June  10, 1994  (the  "Offering  Circular") which  can be
   obtained at  the Company's  offices  in New  York  as  set forth  in  the
   Offering  Circular.   Banque  Scandinave en  Suisse,  acting through  its
   specified office  in Switzerland, has agreed  to provide  services as the
   Exchange Agent  with respect to the exchange of the 8% Bonds due March 1,
   1995 (the  "8%  Bonds") and  Bank Leu  AG, acting  through its  specified
   office  in Switzerland, has  agreed to  provide services  as the Exchange
   Agent with respect to  the exchange of all Bonds other than the 8% Bonds.
   Banque  Scandinave  en  Suisse  and  Bank  Leu  AG  may  be  referred  to
   hereinafter individually  as the  "Exchange Agent"  or, collectively,  as
   the "Exchange  Agents."  The undersigned  hereby directs  you to exchange
   Bonds held by  you for the undersigned's account or which the undersigned
   hereby  delivers to  you  in  the  principal amount  set  forth below  in
   accordance with the provisions of the Offer.

       The Common Stock to be issued  pursuant to the Offer has not
   been registered under the United  States Securities Act of  1933,
   as amended (the "Securities  Act"), and may not be  offered, sold
   or delivered, directly or indirectly, in the United States or to,
   or for the  account of,  any U.S. person  except in  transactions
   exempt from the registration  requirements of the Securities Act.
   In  recognition of  the  fact that  exchanging  holders of  Bonds
   ("Holders"),  even  though holding  shares  of  Common Stock  for
   investment, may wish to  be legally permitted to sell  such stock
   when they deem appropriate, the Company has agreed to prepare and
   file   with  the   Securities   and   Exchange  Commission   (the
   "Commission") a registration statement with respect to the resale
   of the  Common  Stock from  time to  time on  the American  Stock
   Exchange,  Inc. or  Pacific Stock  Exchange, Inc.,  in privately-
   negotiated transactions or otherwise.  The  Company has agreed to
   use  its best  efforts  to cause  such registration  statement to
   become   effective  on  or  before  August  1,  1994.    If  such
   registration  statement   is  not   declared  effective   by  the
   Commission by August  15, 1994, each exchanging  holder will have
   the option to  withdraw the Bonds tendered by  it and to renounce
   its  rights to  the  Common Stock  received  for its  account  in
   exchange for such Bonds.  Notice of such withdrawal must be given
   to the appropriate  Exchange Agent prior to August 30,  1994.  In
   any event, Holders will be  required to agree not to sell  Common
   Stock received by them in the  Offer until the earlier of (a) the
   date which is 40  days after the payment date  for Bonds accepted
   for payment by  the Exchange  Agents pursuant to  the Offer  (the
   "Payment  Date")  and (b)  the  date  on which  the  registration
   statement  covering  such  stock  is declared  effective  by  the
   Commission.    Offers and  sales of  Common  Stock in  the United
                                       -2-

   States  or to U.S. persons would constitute a violation of United
   States  law  unless  made  in compliance  with  the  registration
   requirements of  the Securities Act  or pursuant to  an exemption
   therefrom.

       The  Offer is being  made by the  Company in  reliance on an
   exemption from  the registration  requirements of the  Securities
   Act  of 1933,  as amended  (the "Securities  Act"),  contained in
   Section 3(a)(9) of the Securities Act.  The Offer is intended for
   investors  purchasing  for  investment  and not  with  a  view to
   distribution.

         Tenders  of  Bonds   pursuant  to  these  instructions   are
   irrevocable,  except that they may be withdrawn at any time prior
   to the Expiration  Date.   Bonds may not  be withdrawn after  the
   Expiration Date, except under certain circumstances.

         Payment  for  Bonds  will be  made  on  July  25, 1994  (the
   "Payment  Date"); provided, however,   if the  Company shall have
   extended  the period  of time  for which  the Offer is  open, the
   
       Payment Date shall be the tenth (10th) business day after the
   Expiration Date of the  Offer.  The term "Expiration  Date" means
   5:00  P.M., New  York  City time,  on July  11, 1994,  unless the
   Company  in its sole discretion shall have extended the period of
   time  for which  the  Offer  is open,  in  which event  the  term
   "Expiration Date" shall mean the latest time and date, not beyond
   5:00 P.M.,  New York City time,  on July 25, 1994,  at which time
   the  Offer, as so  extended by the  Company, shall  expire.  Upon
   acceptance  by  the  Company,  the  undersigned  directs  you  to
   deliver, or  cause to be  delivered, to the  appropriate Exchange
   Agent at  its specified  office in  Switzerland, the  Bonds being
   accepted for  exchange, together  with all unmatured  and matured
   but unpaid coupons.  In the event  that unmatured and matured but
   unpaid  coupons are not submitted with Bonds tendered, such Bonds
   will not be accepted for tender.

       Payment for Bonds so  accepted for exchange will be  made on
   the  Payment   Date  by   delivery  of  the   stock  certificates
   representing  the Common  Stock to  the Exchange Agents  at their
   specified  offices  in Switzerland.    The  Exchange Agents  will
   deliver  Common Stock only to  an account or  address outside the
   United States.   The  Exchange Agents will  act as agent  for the
   exchanging  Holders for the purpose of receiving payment from the
   Company and transmitting payments to exchanging Holders.

       Under  federal income  tax  laws, each  tendering holder  of
   Bonds  must  provide  the  Company  with  such  holder's  correct
   taxpayer identification number by completing  the Substitute Form
   W-9 set forth below, unless an exemption applies.  In general, if
   a holder of Bonds  is an individual, the  taxpayer identification
   number is the Social Security number of such individual.   If the
   Company is not provided  with the correct taxpayer identification
   number, the holder may be subject to a $50 penalty imposed by the
   Internal Revenue  Service.   For  further information  concerning
   backup withholding and instructions for completing the Substitute
   Form  W-9  (including how  to  obtain  a taxpayer  identification

                                         -3-

   <PAGE>

   number if  you do not have one and how to complete the Substitute
   Form W-9  if Bonds are held  in more than one  name), consult the
   enclosed Guidelines for  Certification of Taxpayer Identification
   Number on Substitute Form W-9.

       Failure to  complete the  Substitute Form  W-9 will  not, by
   itself, cause  Bonds  to be  deemed invalidly  tendered, but  may
   require the  Company to  withhold  31% of  certain payments  made
   pursuant to the Offer.   Backup withholding is not  an additional
   federal  income tax.  Rather, the federal income tax liability of
   a person subject  to backup  withholding will be  reduced by  the
   amount of tax withheld.  If withholding results in an overpayment
   of taxes, a refund may be obtained.

        In case the Offer  is terminated or expires pursuant  to its
    terms, this Letter of Instructions  shall be cancelled and  Bonds
    tendered will thereupon be at the undersigned's free disposal.

                                  OFFER TO EXCHANGE

   THE OFFER AND WITHDRAWAL RIGHTS  WILL EXPIRE AT 5:00 P.M.,  NEW
   YORK  CITY TIME, ON MONDAY, JULY  11, 1994, UNLESS THE OFFER IS
   EXTENDED OR,  IN  THE CASE  OF  WITHDRAWAL RIGHTS,  SUBJECT  TO
   CERTAIN OTHER EXCEPTIONS.  BONDS MAY NOT BE WITHDRAWN AFTER THE
   EXPIRATION DATE.

       National Patent Development Corporation (the  "Company"), New
   York,  New  York, hereby  offers  (the "Offer")  to  exchange (i)
   common  stock, par value $.01 per  share (the "Common Stock"), of
   the Company with a market value of SFr. 1,000 for each SFr. 1,000
   in principal amount of the Old Swiss Franc Bonds validly tendered
   and  not withdrawn prior to the  Expiration Date, and (ii) Common
   Stock  with a market  value of US  $1,000, for each  US $1,000 in
   principal amount of  the Old U.S.  Dollar Bonds validly  tendered
   and not withdrawn  prior to the Expiration  Date, upon the  terms
   and subject to the conditions set forth in the Offering Circular,
   dated June 10,  1994 (the "Offering Circular"), and in the Letter
   of Instructions.  Interest accrued on the Bonds up to the Payment
   Date will  be paid in shares  of Common Stock of  the Company for
   each  SFr. 1,000 principal amount of  Old Swiss Franc Bonds (such
   amounts  referred   to  collectively   as  "Swiss  Bond   Accrued
   Interest") and  for each US  $1,000 principal  amount of the  Old
   U.S. Dollar Bonds  (such amount referred to as "U.S. Bond Accrued
   Interest," and together with the Swiss Bond Accrued Interest, the
   "Accrued Interest").  Fractional shares of Common Stock resulting
   from such  exchange will be  rounded up  to the nearest  integral
   multiple.   Concurrently with the Offer,  the Company is making a
   separate  offer on the same terms  and for the same consideration
   as  the  Offer  to foreign  holders  of the  Bonds  (the "Foreign
   Offer").

       The  Offer  is  conditioned  upon,  among  other  things, the
   nonoccurrence  of certain events.  The  Company has the right, in
   its sole discretion, to waive any such conditions.

       The  Board  of  Directors  of  the  Company  has  unanimously
   approved  the making of  the Offer; however,  neither the Company
   nor its Board  of Directors is making  any recommendation to  any
   holder of  Bonds to  tender Bonds  pursuant to  the Offer.   Each
   holder of Bonds  should make his own  decision whether to  tender
   his Bonds after reading the Offering Circular.

       Banque  Scandinave en  Suisse,  acting through  its specified
   office  in  Switzerland, has  agreed to  provide services  as the
   Exchange Agent with respect to  the exchange of the 8% Bonds  due
   March 1, 1995  (the "8% Bonds")  and Bank Leu AG,  acting through
   its  specified  office  in  Switzerland, has  agreed  to  provide
   services  as the Exchange Agent  with respect to  the exchange of
   all  Bonds other than the  8% Bonds. Banque  Scandinave en Suisse
   and  Bank Leu AG may  be referred to  hereinafter individually as
   the "Exchange Agent" or, collectively, as the "Exchange Agents."

       Upon the  terms and  subject to the conditions  of the  Offer
   (including,  if the Offer is  extended or amended,  the terms and
   conditions  of any such extension or amendment), the Company will
   accept for exchange  on the Expiration Date Bonds representing up
   to 60% of the aggregate principal amount of the outstanding Bonds
   which  are validly tendered pursuant to the Offer and the Foreign
   Offer  on  or  prior to  the  Expiration  Date  and not  properly
   withdrawn  as permitted  by Section  9 of the  Offering Circular.
   "Expiration  Date" shall mean 5:00  P.M., New York  City time, on
   Monday July 11, 1994, unless the Company, in its sole discretion,
   shall  have extended the  period of time  for which the  Offer is
   open,  in which event the  term "Expiration Date"  shall mean the
   latest  time and date, not beyond 5:00  P.M., New York City time,
   on July 25, 1994, at which time the Offer, as so extended  by the
   Company, shall expire.  Payment  for Bonds exchanged pursuant  to
   the Offer will  be made on  July 25, 1994  (the "Payment  Date"),
   provided, however,  if the Company shall have extended the period
   of time  for which the Offer  is open, the Payment  Date shall be
   the tenth (10th)  business day  after the  Expiration Date,  upon
   timely  receipt by the appropriate Exchange  Agent of such Bonds,
   together  with  all unmatured  and  matured  but unpaid  coupons.
   Tenders  of  Old  Swiss Franc  Bonds  will  be  accepted only  in
   principal amounts  of SFr.  1,000 and integral  multiples thereof
   and tenders of  Old U.S.  Dollar Bonds will  be accepted only  in
   principal amounts  of US  $1,000 and integral  multiples thereof.
   If fractional  Bonds result from proration,  such fractions shall
   be rounded  up to the nearest integral  multiple of SFr. 1,000 or
   US $1,000, as the case may be.

       The Company currently intends to  exchange Bonds representing
   60%  of the aggregate principal  amount of the outstanding Bonds,
   irrespective of the  individual series of the  Bonds, pursuant to
   the  Offer.   The Company  reserves the  right to  exchange Bonds
   representing up to 62%  of the aggregate principal amount  of the
   outstanding Bonds pursuant to the Offer.  If more than 60% of the
   aggregate  principal amount  of the  outstanding Bonds  have been
   properly tendered by the holders thereof  prior to the Expiration
   Date  and  not withdrawn,  the Company  may,  upon the  terms and
   subject to the conditions  of the Offer, either (i)  accept Bonds
   tendered on a pro rata basis according to the aggregate principal

                                         -2-
<PAGE>
   <PAGE>

   amount  of all  Bonds properly  tendered by  the holders  thereof
   prior to the Expiration Date and  not withdrawn or (ii) amend the
   terms of  the Offer  by notice  to the holders  of the  Bonds, in
   which case the Offer shall remain open for an additional ten (10)
   business days from the date that such notice is first  given.  If
   not  more  than   60%  in  aggregate  principal   amount  of  the
   outstanding Bonds  are properly  tendered by the  Expiration Date
   and  not withdrawn, all Bonds so tendered and not withdrawn will,
   upon the  terms and subject  to the conditions  of the  Offer, be
   exchanged.  The Company has the right, in its sole discretion, to
   waive any such conditions.

       For purposes  of the  Offer, the Company shall  be deemed  to
   have accepted for exchange tendered Bonds on the Expiration Date,
   provided that the condition to the Offer set forth in  Section 15
   of  the Offering Circular has been waived or satisfied, unless it
   gives  notice to  the  contrary to  the  Exchange Agents  and  by
   publication in The  Wall Street  Journal no later  than five  (5)
   business  days after the Expiration  Date.  Payment  for Bonds so
   accepted  for exchange will be  made on the  Payment Date, unless
   the conditions set forth  in Section 14  have not been waived  or
   satisfied, by delivery of the stock certificates representing the
   Common Stock to the Exchange Agents at their specified offices in
   Switzerland.  The Exchange Agents  will deliver Common Stock only
   to an account or address outside the United States.  The Exchange
   Agents will act as  agent for the exchanging bondholders  for the
   purpose of  receiving payment  from the Company  and transmitting
   payments to exchanging bondholders.

       For  Bonds to be  exchanged validly pursuant to  the Offer, a
   properly completed  and duly  executed Letter of  Instructions or
   facsimile  thereof  must be  submitted by  or  on behalf  of each
   beneficial  owner of  Bonds  to the  Company  and Bonds  must  be
   submitted to the appropriate Exchange Agent in  Switzerland.  Any
   financial institution  holding Bonds  on  behalf of  one or  more
   beneficial owners may submit  one Letter of Instructions for  all
   such beneficial owners.

       For  a withdrawal  to be  effective, a  written, telegraphic,
   telex  or facsimile  transmission  notice of  withdrawal must  be
   timely sent or delivered by or on behalf of the bondholder to the
   appropriate Exchange  Agent and  received by such  Exchange Agent
   prior to the  Expiration Date.  Bonds may  not be withdrawn after
   the  Expiration Date.  Any such notice of withdrawal must specify
   the name of the bank having tendered on behalf of the bondholder,
   the Bonds to be  withdrawn and the aggregate principal  amount of
   Bonds to be withdrawn.  Withdrawals may only be made in principal
   amounts of SFr. 1,000  or integral multiples thereof in  the case
   of the Old Swiss  Franc Bonds or US $1,000  or integral multiples
   thereof in the case of the Old U.S. Dollar Bonds.  However, Bonds

                                         -3-
<PAGE>
   <PAGE>

   tendered  pursuant to the Offer  also may be  withdrawn after the
   Expiration Date if the registration statement of the Company with
   respect  to the Common Stock  has not been  declared effective by
   the Securities  and Exchange Commission (the  "Commission") on or
   prior to August 15, 1994.


       The Common Stock  to be issued pursuant  to the Offer has not
   been registered under the Securities Act of 1933, as amended (the
   "Securities  Act"),  and may  not be  offered  or sold  except in
   transactions  exempt  from the  registration requirements  of the
   Securities  Act   or  pursuant   to  an  effective   registration
   statement.   In  recognition of  the fact  that holders  of Bonds
   ("Holders"),  even  though holding  shares  of  Common Stock  for
   investment, may wish to  be legally permitted to sell  such stock
   when they  deem appropriate, the  Company, has agreed  to prepare
   and  file  with  the  Commission a  registration  statement  with
   respect to  the resale of the  Common Stock from time  to time on
   the American  Stock Exchange,  Inc., the Pacific  Stock Exchange,
   Inc., in  the  over-the-counter market,  in  privately-negotiated
   transactions or otherwise.   The  Company has agreed  to use  its
   best  efforts  to cause  such  registration  statement to  become
   effective  on or  before August  1, 1994.   If  such registration
   statement  is not declared effective  by the Commission by August
   15, 1994, each exchanging holder will have the option to withdraw
   the Bonds tendered by it and to renounce its rights to the Common
   Stock  received for  its  account  in  exchange for  such  Bonds.
   Notice of such withdrawal  must be given to the  Company prior to
   August  30, 1994.    Offers  and  sales  of  Common  Stock  would
   constitute  a  violation  of United  States  law  unless made  in
   compliance with the  registration requirements of  the Securities
   Act or pursuant to an exemption therefrom.

       Tenders  of Bonds pursuant  to the Offer may be  made only to
   the specified offices of the  Exchange Agents outside the  United
   States.   The Company will  deliver Common Stock  to the Exchange
   Agents outside  the United States,  and the Exchange  Agents will
   deliver, on behalf of  the Company, Common Stock pursuant  to the
   Offer only to an account or address outside the United States.

     To _________________

          National  Patent  Development  Corporation  (the  "Company")  has
     offered (the "Offer") to exchange (i) common stock, par value $.01 per
     share (the "Common Stock"), of the Company with a market value of SFr.
     1,000 for each  SFr. 1,000 in principal amount of  the Old Swiss Franc
     Bonds  validly tendered and not withdrawn prior to the Expiration Date
     and 
     (ii) Common Stock with a market value of US $1,000 for each US  $1,000
     in principal amount of Old U.S.  Dollar Bonds validly tendered and not
     withdrawn prior to the  Expiration Date.  A summary of  the procedures
     for  the Offer  is  described below  and  is fully  set  forth in  the
     Offering Circular dated June 10,  1994 (the "Offering Circular") which
     can be obtained at the  offices in Switzerland of the  Exchange Agents
     set  forth in  the Offering  Circular.   Banque Scandinave  en Suisse,
     acting  through its  specified office  in  Switzerland, has  agreed to
     provide services as the Exchange Agent with respect to the exchange of
     the 8%  Bonds due  March 1,  1995 (the  "8% Bonds")  and Bank  Leu AG,
     acting through  its  specified office  in Switzerland,  has agreed  to
     provide services as the Exchange Agent with respect to the exchange of
     all Bonds  other than the 8%  Bonds.  Banque Scandinave  en Suisse and
     Bank  Leu  AG  may be  referred  to  hereinafter  individually as  the
     "Exchange  Agent"  or, collectively,  as the  "Exchange Agents."   The
     undersigned hereby directs  you to exchange Bonds held  by you for the
     undersigned's  account or which the undersigned hereby delivers to you
     in  the  principal  amount set  forth  below  in  accordance with  the
     provisions of the Offer.

          The Common Stock to be issued pursuant to the Offer  has not been
     registered  under the United States Securities Act of 1933, as amended
     (the "Securities Act"),  and may  not be offered,  sold or  delivered,
     directly or indirectly, in the United States or to, or for the account
     of,  any   U.S.  person  except   in  transactions  exempt   from  the
     registration  requirements of the  Securities Act.   In recognition of
     the fact  that exchanging  holders of  Bonds ("Holders"), even  though
     holding shares  of Common Stock for investment, may wish to be legally
     permitted to sell such  stock when they deem appropriate,  the Company
     has  agreed to  prepare  and file  with  the Securities  and  Exchange
     Commission (the "Commission") a registration statement with respect to
     the resale of the Common Stock from time to time on the American Stock
     Exchange,  Inc.  or  Pacific   Stock  Exchange,  Inc.,  in  privately-
     negotiated transactions or otherwise.   The Company has agreed  to use
     its  best  efforts to  cause  such  registration  statement to  become
     effective on or before August 1, 1994.  If such registration statement
     is  not declared effective by the  Commission by August 15, 1994, each
     exchanging  holder will have the option to withdraw the Bonds tendered
     by it and to renounce its rights to  the Common Stock received for its
     account in exchange for such Bonds.  Notice of such withdrawal must be
     given to  the appropriate Exchange Agent prior to August 30, 1994.  In
     any  event,  Holders  will  be  required  to  agree not  to,  and  the
     undersigned hereby represents and agrees that it will not, sell Common
     Stock received by them in the Offer  until the earlier of (a) the date
     which is 40 days after the payment date for Bonds accepted for payment
     by the Exchange Agents pursuant to  the Offer (the "Payment Date") and
     (b) the date on  which the registration statement covering  such stock
     is  declared effective by the Commission.   Offers and sales of Common

     <PAGE>3

     Stock  in the  United  States or  to U.S.  persons would  constitute a
     violation  of United  States law  unless made  in compliance  with the
     registration requirements  of the  Securities Act  or  pursuant to  an
     exemption therefrom.

          In this Letter of Instructions, references to "dollars",  "$" and
     "US $" are  to United States  dollars, the term "United  States" means
     the United States of America (including the States and the District of
     Columbia), its possessions, its territories and other areas subject to
     its  jurisdiction, and the term  "U.S. person" shall  have the meaning
     set  forth in Sections 230.901 through .904  of Title 17 of the United
     States Code of Federal Regulations ("Regulation S").

          CONSISTENT  WITH THE  FOREGOING LIMITATIONS,  THE OFFER  DOES NOT
     APPLY TO, IS NOT MADE TO, AND MAY NOT BE ACCEPTED BY, HOLDERS OF BONDS
     THAT ARE IN THE UNITED STATES OR THAT ARE U.S. PERSONS.

          Tenders of Bonds pursuant  to these instructions are irrevocable,
     except that  they may be withdrawn at any time prior to the Expiration
     Date  (or, in  certain circumstances  as described  above, at  a later
     time).  Bonds may not be withdrawn after the Expiration Date.

          The  Payment  Date for  Bonds will  be  July 25,  1994; provided,
     however,  if the Company  shall have extended  the period of  time for
     which the  Offer is open, the  Payment Date shall be  the tenth (10th)
     business  day  after  the Expiration  Date  of  the Offer.    The term
     "Expiration Date" means  12:00 Noon,  Geneva time, on  July 11,  1994,
     unless  the Company  in its  sole discretion  shall have  extended the
     period of time for which  the Offer is open,  in which event the  term
     "Expiration  Date" shall  mean the  latest time  and date,  not beyond
     12:00 Noon, Geneva time on July 25,  1994, at which time the Offer, as
     so extended  by the  Company, shall  expire.   Upon acceptance  by the
     Company,  the undersigned  directs  you to  deliver,  or cause  to  be
     delivered, to the  appropriate Exchange Agent at its  specified office
     in  Switzerland, the Bonds being  accepted for exchange, together with
     all  unmatured and  matured but  unpaid coupons.    In the  event that
     unmatured  and matured but unpaid coupons are not submitted with Bonds
     tendered, such Bonds will not be accepted for tender.

          Payment for Bonds  so accepted for  exchange will be made  on the
     Payment Date by  delivery of the  stock certificates representing  the
     Common  Stock to  the Exchange  Agents at  their specified  offices in
     Switzerland.   However,  if  the registration  statement covering  the
     Common Stock is not declared effective by  the Commission prior to the
     Payment Date,  the Common Stock  issued pursuant to the  Offer will be
     represented by  temporary global stock certificates  until the earlier
     of (x) such  time as  the registration statement  covering the  Common
     Stock is declared effective  by the Commission and  (y) 40 days  after
     the  Payment Date.  Such  global stock certificates  will be exchanged
     for   definitive  stock  certificates   upon  certification  that  the
     beneficial owners of such securities are not U.S. persons and have not
     acquired  such securities  for purposes  of resale  to a  U.S. person.
     Prior to exchange for definitive certificates, no stock represented by
     global certificates,  or interests therein,  may be transferred.   The
     Exchange  Agents will  deliver  Common Stock  only  to an  account  or
     address outside  the United States.   The Exchange Agents  will act as

     agent  for the exchanging Holders for the purpose of receiving payment
     from the Company and transmitting payments to exchanging Holders.

          In case the Offer is terminated or expires pursuant to its terms,
     this Letter of  Instructions shall  be cancelled and   Bonds  tendered
     will thereupon be at the undersigned's free disposal.

     decision to be made in respect of the Offer.

                                OFFER TO EXCHANGE

   THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 NOON, GENEVA TIME, ON
   MONDAY, JULY 11, 1994 (THE "EXPIRATION DATE"), UNLESS THE OFFER IS EXTENDED
   OR, IN THE CASE OF WITHDRAWAL RIGHTS, SUBJECT TO CERTAIN OTHER EXCEPTIONS. 
   BONDS MAY NOT BE WITHDRAWN AFTER THE EXPIRATION DATE.

          National  Patent  Development  Corporation  (the  "Company"), New
     York, New  York, hereby offers  (the "Offer")  to exchange (i)  common
     stock, par value  $.01 per share (the "Common Stock"),  of the Company
     with  a market value  of SFr. 1,000  for each SFr.  1,000 in principal
     amount of the Old Swiss Franc Bonds validly tendered and not withdrawn
     prior to the Expiration Date and (ii) Common Stock with a market value
     of US $1,000 for each US $1,000 in principal amount of Old U.S. Dollar
     Bonds validly tendered and not withdrawn prior to the Expiration Date,
     upon the terms and subject to the conditions set forth in the Offering
     Circular, dated June  10, 1994 (the "Offering  Circular"), and in  the
     Letter  of Instructions.   Interest  accrued  on the  Bonds up  to the
     Payment Date will be paid in shares of Common Stock of the Company for
     each  SFr.  1,000  principal amount  of  Old Swiss  Franc  Bonds (such
     amounts referred to collectively as "Swiss Bond Accrued Interest") and
     for each US $1,000 principal amount of the Old U.S. Dollar Bonds (such
     amount referred to  as "U.S. Bond Accrued Interest," and together with
     the Swiss Bond  Accrued Interest, the "Accrued Interest").  Fractional
     shares of Common Stock resulting from such exchange will be rounded up
     to the nearest  integral multiple.  In  accordance with United  States
     securities laws, the  Company is making a concurrent separate offer on
     the same  terms and for  the same consideration  as the Offer  to U.S.
     holders of the Bonds (the "United States Offer").

          The  Offer   is  conditioned   upon,  among  other   things,  the
     nonoccurrence of  certain events.  The  Company has the right,  in its
     sole discretion, to waive any such conditions.

          The  Board of Directors  of the Company  has unanimously approved
     the making of the Offer; however, neither the Company nor its Board of
     Directors  is making  any  recommendation to  any holder  of  Bonds to
     tender Bonds  pursuant to the Offer.  Each holder of Bonds should make
     his own  decision  whether  to  tender his  Bonds  after  reading  the
     Offering Circular.

          Banque Scandinave en Suisse,  acting through its specified office
     in  Switzerland, has agreed to provide  services as the Exchange Agent
     with respect  to the exchange of the  8% Bonds due March  1, 1995 (the
     "8% Bonds") and  Bank Leu AG,  acting through its specified  office in
     Switzerland, has agreed to provide services as the Exchange Agent with
     respect to the exchange of all Bonds other than the 8% Bonds.   Banque
     Scandinave en  Suisse and Bank Leu  AG may be referred  to hereinafter
     individually  as  the  "Exchange   Agent"  or,  collectively,  as  the
     "Exchange Agents."

          Upon  the  terms  and subject  to  the  conditions  of the  Offer
     (including,  if  the  Offer is  extended  or  amended,  the terms  and
     conditions  of any  such  extension or  amendment),  the Company  will
     accept  for exchange on the  Expiration Date Bonds  representing up to
     60% of the aggregate  principal amount of the outstanding  Bonds which
     are validly tendered pursuant to the Offer and the United States Offer
     on or  prior to  the  Expiration Date  and not  properly withdrawn  as
     permitted  by Section 9 of  the Offering Circular.   "Expiration Date"
     shall mean 12:00  noon, Geneva time on  Monday, July 11,  1994, unless
     the Company, in its sole discretion, shall have extended the period of
     time for which the Offer is open, in which event  the term "Expiration
     Date" shall  mean the latest  time and  date, not  beyond 12:00  Noon,
     Geneva Time, on July 25, 1994, at which time the Offer, as so extended
     by the Company, shall expire.  Payment for Bonds exchanged pursuant to
     the Offer  will  be  made  on  July 25,  1994  (the  "Payment  Date"),
     provided,  however, if the Company  shall have extended  the period of
     time  for which the Offer is open, the Payment Date shall be the tenth
     (10th)  business day after the Expiration Date, upon timely receipt by
     the Exchange Agents  of such  Bonds, together with  all unmatured  and
     matured but unpaid coupons.  Tenders of Old Swiss Franc  Bonds will be
     accepted  only  in  principal  amounts  of  SFr.  1,000  and  integral
     multiples  thereof  and  tenders of  Old  U.S.  Dollar  Bonds will  be
     accepted only in principal amounts of US $1,000 and integral multiples
     thereof.   If fractional Bonds  result from proration,  such fractions
     shall be  rounded up to the nearest integral multiple of SFr. 1,000 or
     US $1,000, as the case may be.

          The Company currently intends  to exchange Bonds representing 60%
     of  the   aggregate  principal   amount  of  the   outstanding  Bonds,
     irrespective  of the individual series  of the Bonds,  pursuant to the
     Offer.   The Company reserves the right to exchange Bonds representing
     up to 62%  of the aggregate principal amount of  the outstanding Bonds
     pursuant to  the Offer.  If  more than 60% of  the aggregate principal
     amount of the  outstanding Bonds  have been properly  tendered by  the
     holders  thereof prior to the  Expiration Date and  not withdrawn, the
     Company  may, upon  the terms  and subject  to  the conditions  of the
     Offer, either (i) accept  Bonds tendered on a pro rata basis according
     to  the aggregate principal amount  of all Bonds  properly tendered by
     the holders thereof prior to the Expiration Date  and not withdrawn or
     (ii) amend  the terms  of the Offer  by notice  to the holders  of the
     Bonds, in which case the Offer shall remain open for an additional ten
     (10) business days from the date that such notice  is first given.  If
     not more than  60% in  aggregate principal amount  of the  outstanding
     Bonds  are properly tendered by the Expiration Date and not withdrawn,
     all  Bonds so  tendered  and not  withdrawn will,  upon the  terms and
     subject to the conditions of the Offer, be exchanged.  The Company has
     the right, in its sole discretion, to waive any such conditions.

          For purposes  of the Offer, the  Company shall be deemed  to have
     accepted for exchange tendered  Bonds on the Expiration  Date provided
     that  the condition  to  the Offer  set  forth in  Section  14 of  the
     Offering Circular has been waived or satisfied, unless it gives notice
     to the  contrary in  writing or by  telex to the  appropriate Exchange
     Agent.   The Company will  give notice  and the Exchange  Agents shall
     publish such notice in the Feuille Officielle Suisse du Commerce and a
     daily newspaper  in the cities  of Basle, Geneva  and Zurich  no later

                                         -2-

  <PAGE>

     than five  (5) business days  after the Expiration Date.   Payment for
     Bonds  so accepted  for exchange  will  be made  on the  Payment Date,
     unless the conditions set forth in Section 13 of the Offering Circular
     have not been waived  or satisfied, by delivery of  stock certificates
     representing  the  Common  Stock  to  the  Exchange  Agents  at  their
     specified offices in Switzerland.  Until the earlier  of (x) such time
     as  the registration statement  covering the Common  Stock is declared
     effective by the Securities and Exchange Commission (the "Commission")
     and  (y) 40  days after  the Payment  Date, the  Common Stock  will be
     represented by temporary global stock certificates.  Such global stock
     certificates will be exchanged  for definitive stock certificates upon
     certification that  the beneficial owners  of such securities  are not
     U.S. persons.  Prior to exchange for definitive certificates, no stock
     represented  by  global certificates,  or  interests  therein, may  be
     transferred.  The Exchange Agents will deliver Common Stock only to an
     account or address outside the  U.S.  The Exchange Agents will  act as
     agent  for the  exchanging bondholders  for the  purpose  of receiving
     payment  from  the Company  and  transmitting  payments to  exchanging
     bondholders.

          For  Bonds to  be  validly exchanged  pursuant  to the  Offer,  a
     properly  completed  and  duly  executed Letter  of  Instructions  for
     acceptance  of the Offer or facsimile  thereof must be submitted by or
     on behalf  of each beneficial  owner of Bonds  to one of  the Exchange
     Agents in  Switzerland.   Any financial institution  holding Bonds  on
     behalf  of one  or more  beneficial owners  may submit  one  Letter of
     Instructions for  all such beneficial  owners.  Bonds  physically held
     must be tendered, through a bank in Switzerland,  to an Exchange Agent
     accompanied by  a Letter  of  Instructions signed  by such  beneficial
     owner.   Tenders on behalf of  bondholders will be valid  only if made
     through  banks in  Switzerland and  received by  Banque Scandinave  en
     Suisse, with respect to the 8% Bonds, or Bank Leu AG,  with respect to
     all of the Bonds except the 8% Bonds, prior to the Expiration Date.

          For  a withdrawal to be  effective, a written, telegraphic, telex
     or  facsimile transmission notice of withdrawal must be timely sent or
     delivered  by  or  on behalf  of  the  bondholder  to the  appropriate
     Exchange  Agent and  received  by such  Exchange  Agent prior  to  the
     Expiration Date.  Any such notice of withdrawal  must specify the name
     of the  bank having tendered on behalf of the bondholder, the Bonds to
     be  withdrawn  and  the aggregate  principal  amount  of  Bonds to  be
     withdrawn.  Withdrawals  may only be made in principal amounts of SFr.
     1,000 or integral multiples thereof in the case of the Old Swiss Franc
     Bonds or  US $1,000 or integral  multiples thereof in the  case of the
     Old U.S. Dollar Bonds.  However, Bonds tendered pursuant  to the Offer
     also  may be withdrawn after  the Expiration Date  if the registration
     statement of the Company with respect to the Common Stock has not been
     declared effective by the Commission on or prior to August 15, 1994. 

          The Common Stock to be issued pursuant to the Offer  has not been
     registered  under the United States Securities Act of 1933, as amended
     (the "Securities Act"),  and may  not be offered,  sold or  delivered,
     directly or indirectly, in the United States or to, or for the account
     of,  any   U.S.  person  except   in  transactions  exempt   from  the
     registration  requirements of the  Securities Act.   In recognition of
     the  fact that  exchanging holders of  Bonds ("Holders"),  even though

                                         -3-
<PAGE>
   <PAGE>

     holding shares of Common Stock for investment, may wish  to be legally
     permitted to sell such  stock when they deem appropriate,  the Company
     has  agreed to  prepare and  file with  the Commission  a registration
     statement with  respect to the resale of the Common Stock from time to
     time  on the  American  Stock Exchange,  Inc.,  or the  Pacific  Stock
     Exchange,  Inc., in  privately-negotiated  transactions or  otherwise.
     The  Company  has  agreed  to  use  its  best  efforts  to cause  such
     registration  statement to  become effective  on or  before  August 1,
     1994.  If such registration statement is not declared effective by the
     Commission  by August 15, 1994,  each exchanging holder  will have the
     option to withdraw the Bonds tendered by it and to renounce its rights
     to the  Common Stock received  for its  account in  exchange for  such
     Bonds.   Notice of  such withdrawal must  be given to  the appropriate
     Exchange Agent  prior to August 30,  1994.  Holders agree  not to, and
     the  undersigned hereby represents and  agrees that it  will not, sell
     Common Stock  received by them in  the Offer until the  earlier of (a)
     the date which is 40 days after  the Payment Date and (b) the date  on
     which  the  registration statement  covering  such  stock is  declared
     effective by  the Commission.  Offers and sales of Common Stock in the
     United  States  or to  U.S. persons  would  constitute a  violation of
     United States  law unless  made in  compliance  with the  registration
     requirements  of  the  Securities  Act or  pursuant  to  an  exemption
     therefrom.

          Tenders of  Bonds pursuant to the  Offer may be made  only to the
     specified offices of  the Exchange Agents  outside the United  States.
     The Company will deliver  Common Stock to the Exchange  Agents outside
     the United States, and the Exchange Agents will  deliver, on behalf of
     the Company, Common Stock pursuant to the Offer only to  an account or
     address outside the United States.

          References  herein to  "dollars", "$"  and "US  $" are  to United
     States  dollars, the term "United  States" means the  United States of
     America (including  the  States and  the  District of  Columbia),  its
     possessions,  its  territories   and  other  areas    subject  to  its
     jurisdiction,  and the term "U.S.  person" shall have  the meaning set
     forth  in Sections  230.901 through  .904 of  Title 17  of  the United
     States Code of Federal Regulations ("Regulation S").

        National Patent Development Corporation ("National Patent")  is
   offering (the "Offer"), upon the terms and subject to the conditions
   set forth in its Offering Circular and Letter of Instructions,
   to exchange (i) common stock, par value $.01 per share (the

   U.S. Dollar Bonds validly tendered and not withdrawn prior to the

   will be paid in shares of Common Stock of the Company for each SFr.
   1,000 principal amount of Old Swiss Franc Bonds (such amounts referred

   Accrued Interest, the "Accrued Interest").  Fractional shares of Common
   Stock resulting from such exchange will be rounded up to the nearest
   integral multiple.

           National Patent is concurrently making separate offers to (i)
   U.S. persons holding Bonds and (ii) persons that are not in the United
   States and are not U.S. persons holding Bonds to purchase 60% of the
   aggregate principal amount of the outstanding Bonds.  National Patent is
   offering to pay the same consideration to all holders of the Bonds.

           THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M.,



           The purpose of the Offer is to reduce National Patent's
   long-term indebtedness and annual interest expense, to increase National
   Patent's book value and to provide National Patent with additional
   financial flexibility in its operations.  In addition, the issuance of
   the Common Stock in the Offer will enable National Patent to lower its
   ratio of long-term debt to total capitalization.

            Subject to the terms and conditions of the Offer, National
   Patent will accept for exchange Bonds representing up to 60% of the
   aggregate principal amount of the outstanding Bonds which are validly
   tendered in response to the Offer and not withdrawn prior to the
   Expiration Date.  The term "Expiration Date" means 5:00 P.M., New York
   City time, on July 11, 1994, unless National Patent, in its sole
   discretion, shall have extended the period of time for which the Offer
   is open, in which event the term "Expiration Date" shall mean the latest
   time and date, not beyond 5:00 P.M., New York City time, on July 25,
   1994, at which the Offer, as so extended by National Patent, shall
   expire.  Tenders are irrevocable, except that Bonds tendered pursuant to
   the Offer may be withdrawn prior to 5:00 P.M., New York City time, on
   July 11, 1994 and may be withdrawn thereafter only in certain
   circumstances.

             The Company reserves the right to exchange Bonds representing
   up to 62% of the aggregate principal amount of the outstanding Bonds
   pursuant to the Offer.  In the event that Bonds in excess of 60% of the
   aggregate principal amount are tendered, the Company may either (i)
   accept Bonds tendered on a pro rata basis according to the aggregate
   principal amount of all Bonds properly tendered by the Expiration Date
   or (ii) amend the terms of the Offer by notice to the holders of the
   Bonds, in which case the Offer shall remain open for an additional ten
   (10) business days from the date that such notice is first given.  If
   not more than 60% in aggregate principal amount of the outstanding Bonds
   are properly tendered by the Expiration Date and not withdrawn, all
   Bonds so tendered and not withdrawn will, upon the terms and subject to
   the conditions of the Offer, be exchanged.  The Company has the right,
   in its sole discretion, to waive any such conditions.

             In order to exchange Bonds validly pursuant to the Offer, a
   Letter of Instructions for acceptance of the Offer must be submitted by
   or on behalf of each bondholder to National Patent at its office in New
   York and such Bonds must be submitted to the appropriate Exchange Agent
   at its specified office in Switzerland.  Banque Scandinave en Suisse,
   acting through its specified office in Switzerland, has agreed to
   provide services as the Exchange Agent with respect to the exchange of
   the 8% Bonds due March 1, 1995 (the "8% Bonds") and Bank Leu AG, acting
   through its specified office in Switzerland, has agreed to provide
   services as the Exchange Agent with respect to the exchange of all Bonds
   other than the 8% Bonds.  Any person holding Bonds on behalf of one or
   more beneficial owners may submit one Letter of Instructions for all
   such beneficial owners. 

            Tenders on behalf of bondholders will be valid only if received
   by the Exchange Agents prior to the Expiration Date.  

            The Offer is being made by National Patent in reliance on an
   exemption from the requirements of the Securities Act of 1933, as
   amended, contained in Section 3(a)(9) of such Act.  This notice is being
   published solely in order to comply with the requirements of Rule 13e-4. 
   Pursuant to such Rule, a Schedule 13E-4 has been filed with the
   Securities and Exchange Commission, which information is incorporated by
   reference herein.
