Item 1. Description of Business

(a)  Business Development 

     The Company, a Pennsylvania corporation, incorporated in
1969, is principally engaged in the manufacture and sale of
products used in controlling, modifying, simulating and measuring
environmental factors such as temperature, humidity, pressure,
and vacuum.  These products include aircrew training systems,
sterilizers, environmental and other products which involve
similar manufacturing techniques and engineering technologies.

     Since February 23, 1996, there has been no material change
in the Company's mode of conducting business.

(b)  Business of the Company

     Principal Products  

     Aircrew Training Systems.  The Company's aircrew training
devices are used for medical research, advanced flight training,
and for the indoctrination and testing of military and commercial
pilots.  The major devices sold in this product area are
commercial flight simulators, high altitude decompression
chambers, hyperbaric (high-pressurized oxygen) chambers, night
vision trainers, water survival training equipment,
disorientation training equipment, human centrifuges, and
ejection seat trainers.  The Company provides operation and
maintenance services for installed equipment it manufactures as
well as equipment produced by others.

     The aircrew training system class of products represented
61% and 52% of consolidated revenues of the Company for the years
ended February 28, 1997 and February 23, 1996, respectively.

     Sterilizers.  The Company manufactures steam and gas
sterilizers.  Steam sterilizers are used for hospital, medical
research laboratory, and industrial purposes.  Gas sterilizers
are used for the sterilization of packaged products such as food,
spices, pharmaceutical, and disposable and reusable medical
devices.  The Company's sterilizers range in price from
approximately $25,000 to over $1,000,000, and in chamber size
from three cubic feet to over 4,000 cubic feet, although the
Company concentrates on marketing the larger custom-designed
sterilizers to the pharmaceutical and medical device industries.

     The sterilizer class of products represented 28% and 31% of
consolidated revenues of the Company for the years ended
February 28, 1997 and February 23, 1996, respectively.

     Environmental Systems and Other Products.  The Company's
environmental systems business consists of the design and
fabrication of sampling and analysis systems, and test equipment
and systems used in measuring, monitoring and testing air
pollution.  The Company also designs and manufactures
environmental simulation systems to meet specific needs of its
customers.  The simulation systems generally consist of an
enclosed chamber with instrumentation and equipment which enable
the customer to control and modify such environmental factors as
temperature, pressure, humidity, wind velocity and gas content to
produce desired conditions.  These products include controlled
air systems for automotive companies and environmental chambers.

     The Company also provides repair and maintenance service for
its own and other manufacturers' equipment.

     Sales of these products were 11% and 17% of consolidated
revenues of the Company for the years ended February 28, 1997 and
February 23, 1997, respectively.

     Marketing

     The Company currently markets its products and services
primarily through its officers and employees.  At February 28,
1997, approximately 16 employees were committed to sales and
marketing functions.  The Company uses branch offices in the
United Kingdom, the Middle East, and Asia as well as the services
of approximately 100 independent sales organizations in seeking
foreign orders for its products.

     Product Development

     New products and improvements in existing products are being
continually developed in response to inquiries from customers and
to management's determination that particular products should be
produced or significantly improved.  Although the Company does
not have a separate research and development group, significant
efforts are expended in developing new applications of existing
technologies.

     The Company is currently focusing its product development
efforts in the aircrew training systems segment, with a
particular emphasis on enhancing the related control systems and
software, and exploring commercial possibilities.  The Company
recently completed a Firefighting Command and Control System and
Trainer for a certain foreign governmental agency.  The control
system is a real-time interactive training program that provides
instructor-selective, computer-generated image scenarios that
train and test a firefighter's ability to fight various types of
aircraft fires.  The trainer simulates fires in aircraft and
structures that must be physically fought and controlled by a
team of firefighters.  The Company believes that this development
will provide it with the potential for establishing a new
standardized product for commercial as well as governmental use. 
Additionally, the Company believes this area will expand to
training systems for other disaster situations.

     The Company incurred research and development costs of
approximately $167,000 and $154,000 for the years ended
February 28, 1997 and February 23, 1996, respectively.

     Supplies

     The components being used in the assembly of systems and the
parts used to manufacture the Company's products are purchased
from equipment manufacturers, electronics supply firms and
others.  To date, the Company has had no difficulty in obtaining
supplies.  Further, all raw materials, parts, components, and
other supplies used by the Company in the manufacture of its
products can be obtained at competitive prices from alternate
sources should existing sources of supply become unavailable.

     Patents and Trademarks

     The Company has no patents or trademarks which it considers
significant to its operations, except a patent on the GYROLAB
Spatial Disorientation Trainer which expires in December 2004.

     Customers

     In the current year and recent past, it has been the
Company's experience that a substantial portion of sales are made
to a small number of customers that vary within any given year. 
The Company's business does not depend upon repeat orders from
these same customers.  Sales of aircrew training systems are made
principally to U.S. and foreign governmental agencies.  Sales of
sterilizers and environmental systems are made to commercial and
governmental entities worldwide.

     In fiscal 1997, the Company's major customers included the
United Kingdom, Japan and the U.S. Government, which accounted
for $3,826,000, $2,527,000 and $2,082,000 of the Company's sales,
respectively.  These governmental entities do not have any
relationship with the Company other than as customers.

     Foreign and Domestic Operations and Export Sales

     During the years ended February 28, 1997 and February 23,
1996, approximately $2,082,000 (10%) and $1,631,000 (10%),
respectively, of the Company's net revenues were attributable to
contracts with agencies of the U.S. Government or with other
customers who had prime contracts with agencies of the federal
government.

     During the years ended February 28, 1997 and February 23, 
1996, approximately $15,422,000 (70%) and $9,198,000 (59%),
respectively, of the Company's net revenues were attributable to
export sales or sales for export.  (See Note 10 to the Company's
consolidated financial statements incorporated herein by
reference to the Annual Report.)  On export sales, customers'
obligations to the Company may be secured by irrevocable letters
of credit.

     The Company does not believe that the distribution of its
sales for any particular period is necessarily indicative of the
distribution expected for any other period.

     A large portion of the Company's sales are under long-term
contracts requiring more than one year to complete.  The Company
accounts for sales under long-term contracts on the percentage of
completion basis.  See Notes 1 and 3 to consolidated financial
statements.

     The Company's U.S. Government contracts contain standard
terms permitting termination for the convenience of the
Government.  In the event of termination of such contracts, the
Company is entitled to receive reimbursement on the basis of work
completed (cost incurred plus a reasonable profit), recording the
amounts anticipated to be recovered from termination claims in
income as soon as those amounts can be reasonably determined
rather than at the time of final settlement.  All costs
applicable to a termination claim are charged as an offsetting
expense concurrently with the recognition of income from the
claim.

     Backlog

     The Company's sales backlog at February 28, 1997 and
February 23, 1996 for work to be performed and revenue to be
recognized under written agreements after such dates was
approximately $25,800,000 and $20,900,000, respectively.  In
addition, the Company's training and maintenance contracts
backlog at February 28, 1997 and February 23, 1996 for work to be
performed and revenue to be recognized after that date under
written agreements was approximately $5,100,000 and $2,100,000,
respectively.  Of the 1997 backlog, approximately $21,900,000 is
under contracts for aircrew training systems and maintenance
support principally for U.S. (approximately $300,000) and foreign
governments (approximately $19,000,000).  The U.S. Government
contracts are subject to termination at the convenience of the
Government with equitable cancellation cost recovery. 
Approximately 80% of the 1997 backlog is expected to be completed
prior to February 27, 1998.

     Competition

     The Company's business strategy in recent years has been to
seek niche markets in which there are not numerous competitors. 
However, in some areas of its business the Company competes with
well-established firms, some of which have substantially greater
financial and personnel resources.

     Some competitor firms have technical expertise and
production capabilities in one or more of the areas involved in
the design and production of physiological flight training
equipment, environmental systems, and other specially designed
products, and compete with the Company for this business.  The
competition for any particular project generally is determined by
the technological requirements of the project, with consideration
also being given to a bidder's reliability, product performance,
past performance, and price.

     The Company faces particularly intense competition from a
number of firms in the sale of hospital sterilizers but faces
less competition in the sale of the larger custom-designed
industrial sterilizers.

     The Company believes that it is a significant participant in
the markets in which it competes, especially in aircrew training
systems in which the Company believes it is a principal provider
of this type of equipment and training in its market area.

     Compliance with Environmental Laws

     The Company has not incurred during fiscal 1997 nor does it
anticipate incurring during fiscal 1998 any material capital
expenditures to maintain compliance with Federal, state and local
statutes, rules and regulations concerning the discharge of
materials into the environment, nor does the Company anticipate
that compliance with these provisions will have a material
adverse effect on its earnings or competitive position.

     Employees

     On February 28, 1997, the Company had 189 full-time
employees, of whom 7 were employed in executive positions, 31
were engineers, engineering designers, or draftpeople, 67 were
administrative (sales, accounting, etc.) and clerical personnel,
and 84 were engaged principally in production and operations.

Item 2. Description of Property

     The Company owns its executive offices and principal
production facilities located on a 5-acre site in the County Line
Industrial Park, Southampton, Pennsylvania in an approximately
70,000 square foot steel and masonry building.  Approximately
55,000 square feet are devoted to manufacturing, and
15,000 square feet to office space.  The original building was
erected in 1969 and additions were made in 1973, 1976, 1985 and
1991.  This property collateralizes the Company's revolving
credit facility.

     The Company considers its machinery and plant to be in
satisfactory operating condition and adequate for the Company's
present level of business.  Increases in the level of operations
beyond that expected in the current fiscal year might require the
Company to obtain additional facilities and equipment.

Item 3. Legal Proceedings

     In October 1993, the Company was notified by the Royal Thai
Air Force (the "RTAF") that the RTAF was terminating a certain
$4.6 million simulator contract with the Company.  Although the
Company had performed in excess of 90% of the contract, the RTAF
alleged a failure to completely perform.  In connection with this
termination, the RTAF made a call on a $229,000 performance bond,
as well as a draw on approximately $1.1 million of advance
payment letters of credit.  On October 1, 1996, the Thai Trade
Arbitration Counsel rendered a decision in favor of the Company
pursuant to which the contract was reinstated in full and the
Company was given a period of nine months to complete the
remainder of the work.  Upon completion of the contract, the RTAF
will pay the Company the open receivables balance, consisting of
the performance bond and the advance payment, plus the 10% due on
the balance of the contract.  Based on the progress to date and
recent discussions with the RTAF, the Company estimates it will
probably exceed the nine month contract completion period due to
an extended delay in obtaining an export license for certain
hardware required to complete the project.  This license has now
been received and the hardware has been obtained.  The Company
has submitted a request for a contract extension under the "force
majeure" clause of the RTAF contract, and the RTAF has agreed to
an extension to complete the installation and training.  If the
Company experiences additional delays that are not approved by
the RTAF, the RTAF could invoke penalties against the Company,
including termination of the contract and delay penalties.

     A lawsuit was commenced against the Company in April 1997 in
the United States District Court for the District of Puerto Rico
by an employee of a customer who claims to have been injured as a
result of an alleged malfunction of a sterilizer manufactured by
the Company.  The plaintiff is seeking $3 million in damages. 
Based on the available information, the Company believes that it
possesses meritorious defenses to such action.  The Company has
up to $10 million of products liability coverage, subject to a
$100,000 deductible.   The Company has notified its insurer of
the lawsuit, and the Company's insurer has engaged counsel to
defend the Company in this matter.

     Certain other claims, suits and complaints arising in the
ordinary course of business have been filed or are pending
against the Company.  In the opinion of management, all such
matters are reserved for or are adequately covered by insurance
or, if not so covered, are without merit or are of such kind, or
involve such amounts as would not have a significant effect on
the financial position of the Company if disposed of unfavorably.

     Committees of the Board of Directors

     During the year ended February 28, 1997, the Company had an
Audit Committee consisting of three independent outside
directors:  Messrs. Michael A. Mulshine, Philip L. Wagner and
Dr. Pete L. Stephens.  These three independent outside directors
also served on the Company's Compensation Committee during the
year ended February 28, 1997.  The Audit Committee is charged
with reviewing and overseeing the Company's financial systems and
internal control procedures and conferring with the Company's
independent accountants with respect thereto.  The Compensation
Committee is charged with reviewing the compensation of officers
and key personnel.

     During the year ended February 28, 1997, the Board of
Directors held 6 meetings and the Audit Committee and
Compensation Committee each held 1 meeting.  All members of the
Board attended all of the meetings of the Board held while they

     Compliance With Section 16(a) of the Exchange Act

     Section 16(a) of the Securities Exchange Act of 1934
requires the Company's officers and directors, and persons who
own more than ten percent of a registered class of the Company's
equity securities to file reports of ownership and changes in
ownership with the Securities and Exchange Commission ("SEC") and
the American Stock Exchange.  Officers, directors and greater
than ten percent shareholders are required by SEC regulation to
furnish the Company with copies of all Section 16(a) Forms they
file.  The rules of the SEC regarding the filing of such
statement require that "late filings" of such statements be
disclosed in the Company's proxy statement.

     Based solely on its review of the copies of such forms
received by it, or written representations from certain reporting
persons that no Forms 5 were required for those persons, the
Company believes that, during the fiscal year ended February 28,
1997, its officers, directors and greater than ten percent
beneficial owners complied with all applicable filing
requirements.

                STATEMENT WITH RESPECT TO SHARES

                               OF

               ENVIRONMENTAL TECTONICS CORPORATION

     RESOLVED, that pursuant to the powers expressly delegated to
the Board of Directors by Article 4 of the Articles of
Incorporation of the Company, the Company hereby establishes and
designates one series of preferred stock and fixes and determines
as set forth herein the relative rights and preferences thereof
as follows:  

          Designation.   There shall be established a series of
preferred stock, which shall consist of 25,000 shares of the
authorized preferred stock and shall be designated Series A
Convertible Preferred Stock (herein referred to as the "Preferred
Stock"). 

          Dividends.

          (a)  The holders of Preferred Stock shall be entitled
to receive dividends (the "Preferred Dividend") at the rate of
$11.00 per share per annum (as adjusted for any stock dividends,
combinations, or splits with respect to such shares) on a
cumulative basis from the actual date of original issue of each
share of Preferred Stock (the "Original Issue Date"), whether or
not declared, payable out of funds legally available therefor, on
the first day of each February, May, August, and November in each
year (each a "Dividend Payment Date").  Payments shall commence
on the first such date to occur after the Original Issue Date, to
the holders of record of the Preferred Stock on the fifteenth day
of the month preceding each Dividend Payment Date, in the amount
of $2.75 per share on each Dividend Payment Date, and payable in
the event of a liquidation, dissolution or winding up of the
Company (whether voluntary or involuntary) or upon conversion of
the Preferred Stock as provided in Section 5 and Section 7(a)
hereof.

          (b)  No dividends (other than those payable solely in
the Common Stock of the Company) shall be paid on any Common
Stock of the Company during any fiscal year of the Company until
dividends in the amount of $11.00 per share of the Preferred
Stock (as adjusted for any stock dividends, combinations or
splits with respect to such shares) shall have been paid, or
declared and set apart during that fiscal year and for any prior
year in which dividends have accumulated but remain unpaid.

          (c)  In the event that either (i) the Company fails to
pay the Preferred Dividend on six (6) consecutive Dividend
Payment Dates, or (ii) the aggregate amount of all accumulated
but unpaid dividends shall equal or exceed the amount of $16.50
per share of Preferred Stock, then the holders of the Preferred
Stock shall have the right immediately to elect that number of
members to the Board of Directors as shall constitute a majority
of the Board of Directors.  This right to elect a majority of the
members of the Board of Directors shall continue until all
accumulated but unpaid Preferred Dividends shall have been paid
in full.

          Liquidation, Dissolution, or Winding Up.

          (a)  In the event of any liquidation, dissolution, or
winding up of the Company, whether voluntary or involuntary, the
holders of the Preferred Stock shall be entitled to be paid first
out of the assets of the Company available for distribution to
holders of the Company's capital stock of all classes and before
any sums shall be paid or any assets distributed among the
holders of shares of any other class or series of capital stock
of the Company, including Common Stock, an amount per share equal
to One Hundred Dollars ($100.00) plus the cumulative dividend as
set forth in Section 2(a) hereof whether or not declared, plus an
amount equal to all other accrued but unpaid Preferred Dividends
(the "Preference Amount").  The Preference Amount shall be
tendered to the holders of the Preferred Stock before any sums
shall be paid or any assets distributed to the holders of the
shares of any other class or series of capital stock, including
without limitation Common Stock.  If the assets of the Company
shall be insufficient to permit the payment in full to the
holders of the Preferred Stock of the amounts thus distributable,
then the entire assets of the Company available for such
distribution shall be distributed ratably among the holders of
the Preferred Stock in proportion to the preferential amount each
such holder is otherwise entitled to receive.  After such payment
shall have been made in full to the holders of the Preferred
Stock or funds necessary for such payment shall have been set
aside by the Company in trust for the account of holders of the
Preferred Stock so as to be available for such payment, holders
of the Preferred Stock shall not be entitled to participate in
the distribution of any remaining assets of the Company.

          (b)  Any consolidation, merger or a statutory share
exchange (other than a merger with a wholly-owned subsidiary of
the Company or a consolidation, merger, share exchange or other
business combination in which the outstanding voting stock of the
Company immediately prior to such consolidation, merger, share
exchange or business combination constitutes a majority of the
voting stock of the surviving entity) in which the outstanding
shares of capital stock of the Company are exchanged for
securities or other consideration of or from another corporation,
or a sale of all or substantially all the assets or stock of the
Company, shall be deemed to be a liquidation, dissolution, or
winding up of the affairs of the Company within the meaning of
this Section 3, and shall entitle the holders of the Preferred
Stock to receive on the effective date of such event the
Preference Amount, in cash, securities or other property;
provided, however, that any such event shall not be so regarded
as a liquidation, dissolution, or winding up of the affairs of
the Company with respect to the Preferred Stock if the holders of
two-thirds (2/3) of the outstanding shares of the Preferred Stock
elect not to have any such event deemed to be a liquidation,
dissolution, or winding up of the affairs of the Company by
giving written notice thereof to the Company at least ten (10)
days prior to the effective date of such event.

          (c)  Whenever the distribution provided for in this
Section 3 shall be paid in property other than cash, the value of
such distribution shall be the fair value thereof determined in
good faith by the Board of Directors of the Company.

          J\0  In the event that outstanding shares of Preferred
Stock shall be subdivided into a greater number of shares of
Preferred Stock, the Preference Amount in effect immediately
prior to each such subdivision, simultaneously with the
effectiveness of such subdivision, shall be proportionately
reduced, and, conversely, in case outstanding shares of Preferred
Stock shall be combined into a smaller number of shares of
Preferred Stock, the Preference Amount in effect immediately
prior to each such combination, simultaneously with the
effectiveness of such combination, shall be proportionately
increased.

          Voting Rights; Directors.

          (a)  Except as otherwise required by law, or as
specifically provided herein, the holders of shares of Preferred
Stock and Common Stock shall vote together as a single class on
all matters submitted to a vote of the stockholders of the
Company, with each holder of Preferred Stock entitled to that
number of votes equal to the number of shares of Common Stock
which would be issuable upon conversion of such shares of
Preferred Stock, as provided in Section 5(a) hereof (the "As
Converted Number of Shares") of such holder (with fractional
shares rounded up or down to the nearest whole number) at the
record date for the determination of stockholders entitled to
vote on such matters or, if no such record date is established,
at the date such vote is taken or any written consent of
stockholders is solicited.  The holders of the Preferred Stock
shall be entitled to notice of any stockholders' meeting in
accordance with the Bylaws of the Company.

          (b)  For so long as at least thirty-three and one-third
percent (33 1/3%) of the number of shares of Preferred Stock
issued on the Original Issue Date remain outstanding, the holders
of the Preferred Stock, voting separately as a class, shall be
entitled to elect one (1) member of the Board of Directors.  The
holders of the Preferred Stock shall vote together with holders
of the Common Stock as a single class as provided in Section 4(a)
above for the election of all other members of the Board of
Directors provided that the Board of Directors shall not consist
of more than six (6) members.

          Conversion Rights.  The holders of the Preferred Stock
shall have the following conversion rights:

          (a)  Right to Convert.  Each share of Preferred Stock
shall be convertible at any time, at the option of the holder
thereof, into such number of fully paid and nonassessable shares
of Common Stock as is determined by dividing One Hundred Dollars
($100.00) (the "Numerator") by the Conversion Price (as defined
below) in effect at the time of conversion, provided that all
shares held by such holder are so converted.  The conversion
price at which shares of Common Stock shall be deliverable upon
conversion of Preferred Stock without the payment of additional
consideration by the holder thereof (the "Conversion Price")
initially shall be six dollars ($6.00).  Such initial Conversion
Price, and the rate at which shares of Preferred Stock may be
converted into shares of Common Stock, shall be subject to
adjustment as provided below.  In the event of a liquidation of
the Company, the conversion rights shall terminate at the close
of business on the first full day preceding the date fixed for
the payment of any amounts distributable on liquidation to the
holders of Preferred Stock.

          (b)  Adjustment to Conversion Price Upon Occurrence of
Extraordinary Common Stock Event.  Upon the happening of an
Extraordinary Common Stock Event (as hereinafter defined), the
Conversion Price for the Preferred Stock, simultaneously with the
happening of such Extraordinary Common Stock Event, shall be
adjusted by multiplying the then-effective  Conversion Price by a
fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such Extraordinary
Common Stock Event and the denominator of which shall be the
number of shares of Common Stock outstanding immediately after
such Extraordinary Common Stock Event, and the product so
obtained thereafter shall be the Conversion Price for the
respective series of Preferred Stock.  The Conversion Price, as
so adjusted, shall be readjusted in the same manner upon the
happening of any successive Extraordinary Common Stock Event(s). 
"Extraordinary Common Stock Event" shall mean (i) the issuance of
additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, (ii) a stock split or
subdivision of outstanding shares of Common Stock into a greater
number of shares of Common Stock, or (iii) a reverse stock split
or combination of outstanding shares of Common Stock into a
smaller number of shares of Common Stock.

          (c)  Recapitalization or Reclassification.  If the
Common Stock issuable upon the conversion of the Preferred Stock
shall be changed into the same or a different number of shares of
any class or classes of stock of the Company, whether by
recapitalization, reclassification, or otherwise (other than a
subdivision or combination of shares or stock dividend provided
for in Section 5(b) hereof, or a reorganization, merger, share
exchange, consolidation, or sale of assets provided for in
Section 5(d) hereof), then and in each such event the holder of
each share of Preferred Stock shall have the right thereafter to
convert such share into the kind and amount of shares of stock
and other securities and property receivable upon such
recapitalization, reclassification, or other change by holders of
the number of shares of Common Stock into which such share of
Preferred Stock might have been converted immediately prior to
such recapitalization, reclassification, or change, all subject
to further adjustment as provided herein.

          (d)  Capital Reorganization, Merger, Share Exchange,
Consolidation, or Sale of Assets.  If at any time or from time to
time there shall be a capital reorganization of the Common Stock,
including a merger, share exchange, consolidation, or sale of all
or substantially all of assets of the Company (other than a
subdivision or combination of shares or stock dividend provided
for in Section 5(b) hereof or a recapitalization or
reclassification provided for in Section 5(c) hereof), then, as a
part of such reorganization, provision shall be made so that the
holders of the Preferred Stock thereafter shall be entitled to
receive, upon conversion of each share of the Preferred Stock,
the number of shares of stock or other securities or property to
which a holder of the number of shares of Common Stock into which
such shares of Preferred Stock might have been converted
immediately prior to such capital reorganization would have been
entitled to receive.  In any such case, appropriate adjustment
shall be made in the application of the provisions of this
Section 5 with respect to the rights of the holders of the
Preferred Stock after the reorganization to the end that the
provisions of this Section 5 (including adjustment of the
Conversion Price then in effect and the number of shares acquired
upon conversion of the Preferred Stock) shall be applicable after
that event in as nearly equivalent a manner as may be
practicable.  In the case of a consolidation, merger, share
exchange, or sale of all or substantially all the assets of the
Company, the provisions of Section 3(b) shall apply, and this
Section 5(d) shall not apply, unless the holders of two-thirds
(2/3) of outstanding shares of a series of Preferred Stock elect
that such event shall not be deemed to be a liquidation,
dissolution, or winding up of the affairs of the Company (such
election to be exercised by the holders of two-thirds (2/3) of
the outstanding shares of a series of Preferred Stock by
providing written notice to the Company of such election at least
ten (10) days prior to the date of such consolidation, merger,
share exchange, or sale of all or substantially all the assets of
the Company).

          (e)  Certificate as to Adjustments.  In each case of an
adjustment or readjustment of the Conversion Price of the
Preferred Stock, the Company will furnish each holder of the
Preferred Stock with a certificate prepared by the Chief
Financial Officer of the Company showing such adjustment or
readjustment and stating in detail the facts upon which such
adjustment or readjustment is based.

          (f)  Exercise of Conversion Privilege.  To exercise its
conversion privilege, a holder of Preferred Stock shall surrender
the certificate(s) representing the shares being converted to the
Company at its principal office, accompanied by written notice to
the Company at that office that such stockholder elects to
convert such shares (a "Conversion Notice").  The Conversion
Notice also shall state the name(s) and address(es) in which the
certificate(s) for shares of Common Stock issuable upon such
conversion shall be issued.  The certificate(s) for shares of
Preferred Stock surrendered for conversion shall be accompanied
by proper assignment thereof to the Company or in blank.  The
date when the Conversion Notice is received by the Company
together with the certificate(s) representing the shares of
Preferred Stock being converted shall be the "Conversion Date." 
As promptly as practicable after the Conversion Date, the Company
shall issue and deliver to the holder of the shares of Preferred
Stock being converted, or on its written order, such
certificate(s) as it may request of the number of whole shares of
Common Stock issuable upon the conversion of such shares of
Preferred Stock in accordance with the provisions of this
Section 5 and cash, as provided in Section 5(g), in respect of
any fraction of a share of Common Stock issuable upon such
conversion.  Such conversion shall be deemed to have been
effected immediately prior to the close of business on the
Conversion Date, and at such time the rights of the holder as a
holder of the converted shares of Preferred Stock shall cease and
the person(s) in whose name(s) any certificate(s) for shares of
Common Stock shall be issuable upon such conversion shall be
deemed to have become the holder(s) of record of the shares of
Common Stock represented thereby.

          (g)  Cash in Lieu of Fractional Shares.  No fractional
shares of Common Stock or scrip representing fractional shares
shall be issued upon the conversion of shares of Preferred Stock. 
Instead of any fractional shares of Common Stock that otherwise
would be issuable upon conversion of a series of Preferred Stock,
the Company shall pay to the holder of the shares of Preferred
Stock that were converted a cash adjustment in respect of such
fractional shares in an amount equal to the same fraction of the
Fair Market Value price per share of the Common Stock at the
close of business on the Conversion Date.  "Fair Market Value"
shall mean (i) in the case of a security listed or admitted to
trading on any securities exchange, the last reported sale price,
regular way (as determined in accordance with the practices of
such exchange), on such day, or if no sale takes place on such
day, the average of the closing bid and asked prices on such day
(and in the case of a security traded on more than one national
securities exchange, at such price or such average, upon the
exchange on which the volume of trading during the last calendar
year was the greatest), (ii) in the case of a security not then
listed or admitted to trading on any securities exchange, the
last reported sale price on such day, or if no sale takes place
on such day, the average of the closing bid and asked prices on
such day, as reported by a reputable quotation service designated
by the Company, (iii) in the case of a security not then listed
or admitted to trading on any securities exchange and as to which
no such reported sale price or bid and asked prices are
available, the average of the reported high bid and low asked
prices on such day, as reported by a reputable quotation service,
or the Wall Street Journal, or if there are no bids and asked
prices on such day, the average of the high bid and low asked
prices, as so reported, on the most recent day (not more than
30 days prior to the date in question) for which prices have been
so reported, and (iv) in the case of a security determined by the
Company's Board of Directors as not having an active quoted
market or in the case of other property, such fair market value
as shall be determined by the Board of Directors.  The
determination as to whether any fractional shares are issuable
shall be based upon the total number of shares of Preferred Stock
being converted at any one time by any holder thereof, not upon
each share of Preferred Stock being converted.

          (h)  Reservation of Common Stock.  The Company at all
times shall reserve and keep available out of its authorized but
unissued shares of Common Stock, solely for the purpose of
effecting the conversion of the shares of the Preferred Stock,
such number of its shares of Common Stock as from time to time
shall be sufficient to effect the conversion of all outstanding
shares of the Preferred Stock, and if at any time the number of
authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of all then outstanding
shares of the Preferred Stock, the Company shall take such
corporate action as may be necessary to increase its authorized
but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purpose.

          (i)  Special Adjustment of Conversion Price.   In the
event that the Company enters into a written agreement with the
United Kingdom Ministry of Defense prior to July 31, 1997,
providing for payments to the Company of $19,000,000, then the
Conversion Price shall automatically, be adjusted to $7.50,
subject to further adjustment as set forth in Section 5.

          Restrictions and Limitations.

          (a)  Voting as a Class.  So long as any shares of
Preferred Stock remain outstanding, the Company will not take any
of the following actions without the affirmative vote or consent
(with each share of Preferred Stock being entitled to one vote)
of the holders of at least a majority of the outstanding shares
of the Preferred Stock, given in writing or by resolution adopted
at a meeting called for such purpose:

               (i)  redeem, purchase or otherwise acquire for
     value (or pay into or set aside for a sinking fund for such
     purpose) any share or shares of Preferred Stock otherwise
     than by redemption of Preferred Stock in accordance with
     Section 7 hereof or by conversion in accordance with
     Section 5 hereof;

               (ii)  redeem, purchase or otherwise acquire (or
     pay into or set aside for a sinking fund for such purpose)
     any of the Common Stock, except for (A) the purchase of
     rights to exercisable options under the Company's 1988
     Incentive Stock Option Plan in an amount not to exceed the
     difference between the exercise price of such option and the
     Fair Market Value of the Common Stock on the date of
     purchase by the Company, or (B) the purchase of the warrant
     for 100,000 shares of Common Stock held by Chase Manhattan
     Capital Corporation, for an amount not to exceed $375,000; 

               (iii)  authorize or issue, or obligate itself to
     issue, any other equity security senior to or on a parity
     with the Preferred Stock as to dividend rights or redemption
     rights or liquidation preferences;

               (iv)  consolidate or merge with (other than a
     merger with a wholly-owned subsidiary of the Company or a
     consolidation, merger, share exchange or other business
     combination in which the outstanding voting stock of the
     Company immediately prior to such consolidation, merger,
     share exchange or business combination constitutes a
     majority of the voting stock of the surviving entity) or
     into, or sell or license all or substantially all the assets
     of the Company to, any other person or entity, liquidate,
     dissolve, or wind-up the affairs of the Company,
     recapitalize the outstanding capital stock of the Company,
     or reorganize the affairs of the Company;

               (v)  increase or decrease (other than by
     redemption or conversion) the total number of authorized
     shares of Preferred Stock; or

               (vi)  effect an exchange, reclassification or
     cancellation of all or part of the shares of Preferred Stock
     or Common Stock, or effect an exchange, or create a right of
     exchange, of all or part of the shares of another class or
     series into the shares of Preferred Stock or Common Stock,
     whether in securities of the Company or another corporation.

          (b)  Voting by Series of Preferred Stock.  The Company
shall not amend its Articles of Incorporation or Bylaws without
the approval of the holders of a majority of the outstanding
shares of Preferred Stock if such amendment would:

               (i)  reduce the dividend rates on the Preferred
     Stock provided for herein, make such dividends
     noncumulative, defer the date from which dividends will
     accrue, cancel accrued and unpaid dividends, or change the
     relative seniority rights of the holders of the Preferred
     Stock as to the payment of dividends in relation to the
     holders of any other capital stock of the Company;

               (ii)  reduce the amount payable to the holders of
     the Preferred Stock upon the voluntary or involuntary
     liquidation, dissolution or winding up of the Company, or
     change the relative seniority of the liquidation preferences
     of the holders of the Preferred Stock;

               (iii)  reduce the Redemption Price specified in
     Section 7 hereof with respect to such series;

               (iv)  delay any of the Redemption Dates provided
     for in Section 7 hereof;

               (v)  cancel or modify the conversion rights of the
     Preferred Stock provided for in Section 5 hereof; or 

               (vi)  otherwise amend its Articles of
     Incorporation if such amendment would change adversely any
     of the rights, preferences or privileges provided for 
     herein for the benefit of any shares of Preferred Stock. 

     Redemption.

          (a)  Preferred Stock Right of Redemption; Automatic
Conversion.  The Company shall redeem, from any source of funds
legally available therefor, the Preferred Stock of each holder
thereof in three (3) annual installments beginning on the fifth
(5th) anniversary of the Original Issue Date (each a "Redemption
Date"), unless such holder has elected to waive its right of
redemption as provided herein.  The Company shall effect this
redemption by paying in cash to each such holder for each share
of Preferred Stock a sum equal to One Hundred Dollars ($100.00)
per share (as adjusted for any stock dividends, combinations, or
splits with respect to such shares), plus an amount equal to all
accumulated but unpaid dividends for the shares to be redeemed
(the "Redemption Price").  A holder of Preferred Stock may elect,
by written notice delivered to the Company not less than
twenty-one (21) days prior to the Redemption Date, to waive its
right to have redeemed all (but not less than all) of the shares 
of Preferred Stock held by such holder which are eligible to be
redeemed on such Redemption Date, provided that on such
Redemption Date each such share of Preferred Stock which is not
redeemed shall be converted automatically into shares of Common
Stock at the Conversion Price then in effect on such Redemption
Date.  The number of shares of Preferred Stock that the Company
shall be required under this Section 7(a) to redeem on each
Redemption Date shall be 8,333 shares, except that the Company
shall be required to redeem all the shares of Preferred Stock
outstanding on the seventh (7th) anniversary of the Original
Issue Date.  Any redemption shall be made on a pro rata basis
among the holders of the Preferred Stock in proportion to the
shares of such series of Preferred Stock then held by them. 

          (b)  Redemption at the Option of the Company.  The
Preferred Stock may not be repurchased by the Company at the
option of the Company at any time prior to the second anniversary
of the Original Issue date.  Notwithstanding anything herein to
the contrary, on and after the second anniversary of the Original
Issue Date, the Preferred Stock shall be subject to redemption,
at the  option of the Company, in whole or in part, at any time
or from time to time (a "Called Redemption Date"), provided that
the average bid price for the Common Stock has been greater than
$9.50 per share during the twenty (20) business days prior to the
date of the Redemption Notice (as defined below).  The procedure
for the redemption or repurchase of the Preferred Stock by the
Company pursuant to the provisions of this Section 7(b) shall be
as set forth in Section 7(c) below.

          (c)  Procedures for Redemption of Preferred Stock.  At
least thirty (30) days but not more than forty-five (45) days
prior to each Redemption Date the Company shall mail a written
notice, first class postage prepaid, to each holder of record at
the close of business on the business day preceding the day on
which notice is given, of the Preferred Stock to be redeemed, at
the address last shown on the records of the Company for such
holder, notifying such holder of the redemption to be effected,
specifying (i) the number of shares to be redeemed from such
holder, (ii) the Redemption Date, (iii) the Redemption Price,
(iv) the place at which payment may be obtained, (v) advising
such holder of its right to elect to waive its right to have all
(but not less than all) such shares redeemed and that, if such
election is made, such shares of Preferred Stock which are not
redeemed shall be converted automatically into shares of Common
Stock at the Conversion Price then in effect (setting forth such
Conversion Price), and (vi) calling upon such holder to surrender
to the Company, in the manner and at the place designated, its
certificate or certificates representing the shares to be
redeemed (the "Redemption Notice").  On or after the Redemption
Date, each holder of Preferred Stock to be redeemed shall
surrender to the Company the certificate or certificates
representing such shares, in the manner and at the place
designated in the Redemption Notice, and thereupon the Redemption
Price of such shares shall be payable to the order of the person
whose name appears on such certificate or certificates as the
owner thereof and each surrendered certificate shall be canceled. 
In the event less than all the shares represented by any such
certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.  From and after each
Redemption Date, unless there shall have been a default in
payment of the Redemption Price, any shares of Preferred Stock
redeemed on such Redemption Date shall not be entitled to any
further rights as Preferred Stock and shall not be deemed
outstanding for any purpose.  If the funds of the Company legally
available for redemption of shares of Preferred Stock on any
Redemption Date are insufficient to redeem the total number of
shares of Preferred Stock to be redeemed on such date, those
funds which are legally available will be used to redeem the
maximum possible number of such shares ratably among the holders
of such shares to be redeemed based upon the number of shares of
Preferred Stock held by each such holder.  The shares of
Preferred Stock not redeemed shall remain outstanding and
entitled to all the rights and preferences provided herein.  At
any time thereafter when additional funds of the Company are
legally available for the redemption of shares of Preferred Stock
such funds will be used immediately to redeem the balance of the
shares which the Company has become obliged to redeem on any
Redemption Date, but which it has not redeemed, it being
understood that any such redemption shall not constitute a waiver
by a holder of Preferred Stock of any rights derived from the
failure to redeem on the Redemption Date.

     No Reissuance of Convertible Preferred Stock.  No share(s)
of Preferred Stock acquired by the Company by reason of
redemption, purchase, conversion, or otherwise shall be reissued,
and all such shares shall be canceled, retired, and eliminated
from the shares that the Company shall be authorized to issue. 
The Company from time to time may take such appropriate corporate
action as may be necessary to reduce the authorized number of
shares of the Preferred Stock accordingly.

     No Dilution or Impairment.  The Company will not, by
amendment of its Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, share
exchange, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or
performance of any of the terms of the Preferred Stock set forth
herein, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such
action as may be necessary or appropriate in order to protect the
rights of the holders of the Preferred Stock against dilution or
other impairment.

          Notices of Record Date.  In the event of any:

          (a)  taking by the Company of a record of the holders
of any class of securities for the purpose of determining the
holders thereof who are entitled to receive any dividend or other
distribution, or any right to subscribe for, purchase, or
otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right; or

          (b)  capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the
Company, any merger, consolidation, or share exchange of the
Company, or any transfer of all or substantially all the assets
of the Company to any other corporation, or any other entity or
person; or

          (c)  voluntary or involuntary dissolution, liquidation,
or winding up the Company;

then and in each such event the Company shall mail or cause to be
mailed to each holder of Preferred Stock a notice specifying
(i) the record date for such dividend, distribution, or right and
a description of such dividend, distribution, or right, (ii) the
date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, share
exchange, dissolution, liquidation, or winding up is expected to
become effective, and (iii) the time, if any, that is to be fixed
as to when the holders of record of Common Stock (or other
securities) shall be entitled to exchange their shares of Common
Stock (or other securities) for securities or other property
deliverable upon such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, share
exchange, dissolution, liquidation, or winding up.  Such notice
shall be mailed at least ten (10) days prior to the date
specified in such notice on which such action is to be taken.

     2.1  The Line of Credit.  The Bank shall make available to
the Borrower, commencing on the Closing Date, a Revolving Credit
Facility in the maximum principal amount of $10,000,000.00 (the
"Revolving Facility Commitment"), upon the terms and conditions
set forth herein.  After May 31, 1998, the Revolving Facility
Commitment shall be reduced to $9,000,000.

          (a)  Generally.  At any time and from time to time
during the period commencing on the Closing Date and ending on
the Termination Date, upon the request of the Borrower, the Bank
shall provide to the Borrower a loan or loans which shall be used
by the Borrower for working capital and/or repayment of
indebtedness existing at the time of the Closing (the "Line of
Credit").  Subject to Section 2.2(b)(2), any loan request by the
Borrower shall be in a minimum amount of $100,000.00.  To the
extent a loan request exceeds $100,000.00, such excess shall be
in multiples of $100,000.00.  The Borrower may use the Line of
Credit during the period referred to in the preceding sentence by
borrowing, repaying and reborrowing in accordance with the terms
of this Agreement.  On and before May 31, 1998, the aggregate
outstanding principal under the Line of Credit at any time shall
not exceed $9,000.000.00.  After May 31, 1998, the aggregate
outstanding principal under the Line of Credit at any time shall
not exceed $8,000,000.  If, at any time, the aggregate
outstanding principal under the Line of Credit exceeds: (i) on or
before May 31, 1998, $9,000,000.00 or (ii) after May 31, 1998,
$8,000,000.00, then, without any requirement of demand or notice
from the Bank, the Borrower shall immediately pay to the Bank the
amount of such excess.  Upon the Termination Date, unless the
same has been extended by written agreement between the Bank and
the Borrower (which the Bank shall provide, if at all, no later
than forty-five (45) days prior to the Termination Date), the
Bank's commitment to make Line of Credit Loans shall terminate,
all Line of Credit Loans shall immediately mature and all
Obligations under the Revolving Credit Facility shall be
immediately due and payable in full.

          (b)  Letters of Credit.

               (1)  Generally.  In addition to making loans to
the Borrower under the Line of Credit as provided in
Section 2.1(a) hereof, the Bank shall, upon the request of the
Borrower and subject to the terms of this Agreement, also issue
one or more standby letters of credit ("Letters of Credit") for
the account of the Borrower to benefit customers of the Borrower
that have advanced funds to the Borrower or have executed
maintenance contracts with the Borrower.  The cumulative face
amount of all outstanding Letters of Credit, together with the
Chase Letters of Credit, shall at no time exceed $2,000,000.00. 
All amounts drawn under Letters of Credit shall be deemed to be
evidenced by the Line of Credit Note, and the amount available to
be borrowed under the Revolving Credit Facility shall be reduced
by the aggregate amounts drawn and available to be drawn at any
time under all outstanding Letters of Credit.  In no event shall
the aggregate amount available to be drawn on all outstanding
Letters of Credit plus the Chase Letters of Credit plus the
outstanding principal balance of Line of Credit Loans exceed the
Revolving Facility Commitment.  In such an event, the Borrower
shall immediately pay to the Bank the amount of such excess.  The
duration of any Letters of Credit shall not extend beyond the
Termination Date without the prior written consent of the Bank. 
Upon an Event of Default under this Agreement, the Bank may, at
its option, cause to be advanced Adjusted Base Rate Loans from
the Revolving Credit Facility in an amount up to the face amount
of the Letters of Credit.  The proceeds of any advance made
pursuant to this paragraph shall be deposited with the Bank in a
deposit account maintained at the Bank which shall constitute a
portion of the Collateral.  In the event that any outstanding
Letters of Credit are thereafter returned to the Bank without any
drafts or demands for payment having been made thereon, then from
any sums then on deposit in the foregoing account an amount shall
be applied to the then outstanding principal balance of the
Revolving Credit Facility which is equal to the face amount of
each such returned Letter of Credit.

               (2)  Issuance of Letters of Credit.  Subject to
the provisions of Section 2.1(b)(1), the Bank shall issue Letters
of Credit for the account of the Borrower, provided that the
Borrower (i) provides a written request for each such Letter of
Credit specifying the terms thereof, including, without
limitation, the amount and the name and address of the
beneficiary of such Letter of Credit; (ii) executes and delivers
to the Bank an application for each such Letter of Credit
pursuant to the form provided for such purpose by the Bank; and
(iii) executes and delivers to the Bank such other documents and
instruments which the Bank, in its sole and absolute discretion,
deems reasonable and necessary.  The Borrower shall pay to the
Bank on the date of issuance of each Letter of Credit hereunder a
fee equal to the face amount of the Letter of Credit multiplied
by 1.5% less the Letter of Credit Fee Reduction, if any.  The
foregoing fees may be deducted by the Bank from the Borrower's
accounts maintained at the Bank as such fees are incurred.  The
determination of whether the Borrower is entitled to a Letter of
Credit Fee Reduction shall be made in connection with the
Borrower's delivery of the certificate required to be delivered
by the Borrower to the Bank pursuant to Section 6.2 of this
Agreement.  Letter of Credit Fee Reductions for future Letters of
Credit will become effective upon the first Business Day of the
fiscal quarter following the Bank's receipt of the above-
described certificate.

          (c)  Interest.  Interest shall accrue on all loans
outstanding under the Line of Credit at the rate or rates set
forth in Section 2.2 hereof.

          (d)  Line of Credit Note.  The obligations of the
Borrower to repay the aggregate outstanding principal under the
Revolving Credit Facility and to pay accrued interest on Line of
Credit Loans shall be evidenced by a promissory note, in form and
substance satisfactory to the Bank, to be executed and delivered
to the Bank concurrently with the execution and delivery of this
Agreement (the "Line of Credit Note").

          (e)  Commitment Fees.  In addition to any and all other
fees required to be paid by the Borrower in accordance with the
terms of this Agreement, the Borrower shall pay to the Bank on
the first Business Day of each of Borrower's fiscal quarters a
commitment fee equal to 0.05% of the average unused balance of
the Revolving Facility Commitment during the preceding fiscal
quarter. 

     2.2  Interest. Interest shall accrue on the outstanding
principal amounts of the Line of Credit Loans in accordance with
the following provisions:

          (a)  Applicable Rates.  At the Borrower's election, the
Line of Credit Loans shall bear interest at any one of the
following rates (the "Applicable Rates"):

               (1) the Adjusted Base Rate, such rate to change
simultaneously and automatically upon the Bank's designation of
any change in the Base Rate; or

               (2) the Adjusted LIBO Rate.  

          (b)  Determination of Interest Periods and Applicable
Rates.  Interest Periods and the Applicable Rates shall be chosen
with respect to Line of Credit Loans as follows:

               (1)  The Borrower may ask the Bank for indications
of LIBOR for specified Line of Credit Loans and Interest Periods,
as applicable, at any time.  If the Borrower anticipates that it
may elect the Adjusted LIBO Rate to be applicable to a Line of
Credit Loan, the Borrower shall request an indication of LIBOR
prior to 11:00 a.m. (Philadelphia time) at least three Eurodollar
Business Days prior to the commencement of the applicable
Interest Period, and if the Borrower desires to elect the
Adjusted LIBO Rate for such Interest Period, the Borrower must
accept such indication of LIBOR by notice to the Bank in writing
or by telephone (confirmed promptly in writing) prior to
11:00 a.m. (Philadelphia time) on the date of acceptance, which
shall be at least two Eurodollar Business Days prior to the
commencement of the Interest Period selected by the Borrower.  If
the Borrower does not provide the applicable notice of election
of the Adjusted LIBO Rate, then the Borrower shall be deemed to
have requested that the Adjusted Base Rate apply to any Line of
Credit Loan which is subject to any expiring Interest Period and
to any new Line of Credit Loan, as the case may be, until the
Borrower shall have given appropriate notice of a requested
change in or determination of the rate of interest in accordance
with this Section 2.2.  No acceptance of an indication of rate
hereunder shall bind the Bank unless timely made.

               (2)  The Borrower shall not request and the Bank
shall not be required to provide, an indication of LIBOR with
respect to a specified Interest Period for any Line of Credit
Loan of less than $500,000.

               (3)  All determinations and quotations of rate by
the Bank hereunder shall be conclusive and binding upon the
Borrower, in the absence of manifest error.

               (4)  If no Interest Period is elected with respect
to any Adjusted LIBO Rate Loan, the request for such Line of
Credit Loan shall be deemed to be a request for a thirty day
Interest Period in respect of any such Adjusted LIBO Rate Loan.

               (5)  Upon the occurrence of any Event of Default
and a resulting acceleration of Obligations pursuant to
Section 9.1(b) hereof, all Interest Periods shall automatically
terminate and all Adjusted LIBO Rate Loans shall be automatically
converted to Loans bearing interest at the Default Rate and shall
be subject to the payment of all amounts then due with respect to
such termination under Section 2.4 hereof. 

          (c)  Payment of Interest.  Notwithstanding anything to
the contrary in this Agreement, the Borrower shall pay interest
accruing at the Adjusted LIBO Rate monthly in arrears on the
first Business Day of each consecutive calendar month during an
Interest Period commencing on the first such date next succeeding
the date on which such Interest Period commenced, and on the
expiration date of such Interest Period.  The Borrower shall pay
interest on all Line of Credit Loans other than Adjusted LIBO
Rate Loans monthly in arrears on the first day of each
consecutive calendar month commencing with the month immediately
following the date on which the first advance under the Line of
Credit is made.  All accrued but unpaid interest under the Note
shall be payable, without demand, on the maturity thereof
(whether by its stated terms, or upon prepayment, acceleration or
otherwise).

          (d)  Default Rate.  Notwithstanding anything to the
contrary contained in this Section 2.2, upon the occurrence of an
Event of Default under this Agreement, all Line of Credit Loans
shall bear interest at the Default Rate.

     2.3  Conversion and Continuation of Loans.  The Borrower may
convert any Line of Credit Loan to an Adjusted LIBO Rate Loan or
continue any Adjusted LIBO Rate Loan subject to an expiring
Interest Period for an additional Interest Period upon the same
advance notice required pursuant to Section 2.2 hereof, subject,
however, to the all of the terms of this Agreement, including,
without limitation, the following:

          (a)  Rate Availability.  An Adjusted LIBO Rate shall be
available, notwithstanding Section 2.4(a) hereof.

          (b)  Limitation on Interest Period.  No Interest Period
may be elected with respect to any Line of Credit Loan (i) which
would expire after the Termination Date in the case of an
Adjusted LIBO Rate Loan, or (ii) for a period other than those
referred to in the definition of "Interest Period" set forth in
Article I hereof.

          (c)  Payment of Interest; No Default.  All interest
accrued under an expiring Interest Period shall be paid by the
Borrower on the last day of such Interest Period, and no
continuation or conversion of a Line of Credit Loan subject to an
expiring Interest Period shall be made for so long as an Event of
Default shall be continuing.

          (d)  Timing.  No continuation or conversion of an
Adjusted LIBO Rate Loan may be effected on other than the last
day of the Interest Period then in effect with respect to such
Adjusted LIBO Rate Loan, and a Line of Credit Loan which is not
an Adjusted LIBO Rate Loan may be converted into an Adjusted LIBO
Rate Loan only on a Eurodollar Business Day.

          (e)  Failure to Give Notice.  In the event that the
Borrower shall not give notice to continue any Adjusted LIBO Rate
Loan into a subsequent Interest Period in accordance with
Section 2.2 hereof, the Borrower shall be deemed to have
requested that such Adjusted LIBO Rate Loan (unless repaid) be
converted to one accruing interest at the Adjusted Base Rate, at
the expiration of the then current Interest Period.

     2.4  Special Provisions Applicable to Adjusted LIBO Rate
Loans. The following special provisions shall apply to Adjusted
LIBO Rate Loans:

          (a)  Mandatory Suspension and Conversion of Adjusted
LIBO Rate Loans.  The Bank's obligations to make, maintain or
convert into Adjusted LIBO Rate Loans of any type shall be
suspended, all outstanding Adjusted LIBO Rate Loans shall be
converted on the last day of their applicable Interest Periods
(or, if earlier, in the case of clause (2) below, on the last day
the Bank may lawfully continue to maintain Adjusted LIBO Rate
Loans or, in the case of clause (3) below, the day determined by
such Bank to be the last Business Day before the effective date
of the applicable restriction) into, and all pending requests for
the making of or conversion into Adjusted LIBO Rate Loans shall
be deemed requests for, Line of Credit Loans at the Adjusted Base
Rate if:

               (1)  on or prior to the determination of the
interest rate for an Adjusted LIBO Rate Loan for any Interest
Period, the Bank determines that for any reason appropriate
quotations are not available to it (including, quotations in the
interbank market selected by it for deposits with it) for
purposes of determining the Adjusted LIBO Rate or in the good
faith reasonable judgment of the Bank, that such rate would not
accurately reflect the cost to the Bank of making, maintaining or
converting into an Adjusted LIBO Rate Loan of such type for such
Interest Period;

               (2)  at any time the Bank determines, in the
exercise of its good faith reasonable judgment, that any
Regulatory Change makes it unlawful or impracticable for such
Bank to make or maintain any Adjusted LIBO Rate Loan, or to
comply with its obligations hereunder in respect thereof; or

               (3)  the Bank determines, in the exercise of its
good faith reasonable judgment, that by reason of any Regulatory
Change it is restricted, directly or indirectly, in the amount
that it may hold of (x) a category of liabilities that include
deposits by reference to which, or on the basis of which, the
interest rate applicable to Adjusted LIBO Rate Loans is directly
or indirectly determined, or (y) the category of assets that
includes Adjusted LIBO Rate Loans.

          The Bank shall promptly give notice to the Borrower of
any circumstance that would make the provisions of this
Section 2.4(a) applicable, but the failure to give any such
notice shall not affect such Bank's rights hereunder.

          (b)  Regulatory Changes.  If any Regulatory Change:

               (1)  shall subject the Bank to any Tax determined
by the Bank to be applicable to any Adjusted LIBO Rate Loan, to
the Bank's obligation to make or maintain any such Adjusted LIBO
Rate Loan, to this Agreement or the Note, or shall, in the
determination of the Bank, change the basis of taxation of
payments to the Bank of the principal of or interest on any
Adjusted LIBO Rate Loan or of any other amounts payable under
this Agreement in respect of any Adjusted LIBO Rate Loan or its
obligation to make or maintain any Adjusted LIBO Rate Loan; or

               (2)  shall impose, increase, modify or deem
applicable any Tax, reserve, insurance charge, special deposit,
assessment or other requirement or condition (other than reserves
and assessments taken into account in the calculation of the
Adjusted LIBO Rate) against assets of, deposits with or to the
account of, credit extended by, or the obligations of the Bank
under this Agreement, or shall impose on the Bank or on any
relevant interbank market for U.S. Dollars, any condition; and
the result of the foregoing, in the determination of the Bank, is
to (x) reduce the amount of any sum received or receivable by the 
Bank with respect to any Adjusted LIBO Rate Loan or the return to
be earned by the Bank on any such Loan, (y) impose a cost on the
Bank that is attributable to the making or maintaining of, or its
commitment to make, any such Adjusted LIBO Rate Loan, or
(z) require the Bank to make any payment on, or calculated by
reference to, the gross amount of any amount received by it
hereunder or under any such Loan, then, within 15 days after
request by the Bank, the Borrower shall pay to the Bank such
additional amount or amounts as the Bank determines will
compensate the Bank for such reduction, increased cost or
payment.  The Bank will promptly notify the Borrower of any
Regulatory Change of which it has knowledge that will entitle the
Bank to compensation pursuant to this Section 2.4(b), but the
failure to give such notice shall not affect the Bank's right to
such compensation.  The Bank agrees to take any reasonable action
which the Bank determines, in its discretion, may be available
without cost or expense to the Bank in order to eliminate or
mitigate the effect of such Regulatory Change.

          (c)  Funding Losses.  The Borrower shall pay to the
Bank, upon request, such amount or amounts as the Bank determines
are necessary to compensate it for any loss, cost or expense
incurred by it as a result of (i) any payment, prepayment or
conversion of an Adjusted LIBO Rate Loan on a date other than the
last day of an Interest Period for such Adjusted LIBO Rate Loan
or (ii) an Adjusted LIBO Rate Loan for any reason not being made
or converted, or any payment of principal thereof or interest
thereon not being made, on the date therefor determined in
accordance with the applicable provisions of this Agreement. 
Such amount shall equal the excess of (x) the interest that would
have been received from the Borrower under this Agreement on any
amounts to be redeployed during an Interest Period or its
remaining portion over (y) the interest component of the return
that the Bank determines it could have obtained had it placed
such amount on deposit in the interbank market selected by it for
a period equal to such Interest Period or its remaining portion.

     2.5  Requirements of Law.  In the event that after the date
hereof, any change in any law, regulation or treaty or in the
interpretation or application thereof or compliance by the Bank
with any request or directive (whether or not having the force of
law) from any central bank or other governmental authority,
agency or instrumentality:

          (a)  subjects or shall subject the Bank to any tax of
any kind whatsoever with respect to this Agreement, the loans
made hereunder or the issuance or maintenance of the Letters of
Credit hereunder, or changes the basis of taxation of payments to
the Bank of principal, commitment fees, interest or any other
amount payable hereunder (except for changes in the rate of tax
on the overall net income of the Bank);

          (b)  imposes, modifies or holds or shall impose, modify
or hold applicable any reserve, special deposit, compulsory loan
or similar requirement against assets held by, or deposits or
other liabilities in or for the account of, advances or loans by,
or other credit extended by, or any other acquisition of funds
by, any office of the Bank, which reserve, special deposit,
compulsory loan or similar requirement is not otherwise included
in determination of the interest rate hereunder;

          (c)  imposes or shall impose on the Bank any other
condition;

and the result of any of the foregoing is to, directly or
indirectly, increase the cost to the Bank of making, renewing or
maintaining advances or extensions of credit or issuing or
maintaining Letters of Credit or to reduce any amount receivable
thereunder then, in any such case, the Borrower shall promptly
pay the Bank, upon its demand, any additional amounts necessary
to compensate the Bank for such additional cost or reduced amount
receivable.  If the Bank becomes entitled to claim any additional
amounts pursuant to this subsection, it shall promptly notify the
Borrower of the event by reason of which it has become so
entitled.  The good faith determination as to any additional
amounts payable pursuant to the foregoing sentence by the Bank
shall be conclusive in the absence of manifest error.

     2.6  Determinations.  In making the determinations
contemplated by Section 2.4 and 2.5 hereof the Bank may make such
estimates, assumptions, allocations and the like that it, in good
faith, determines to be appropriate.  All such determinations
shall be final, binding and conclusive upon the Borrower, except
to the extent of any manifest error in computation or
transmission.  The Bank shall furnish to the Borrower, upon
request, a certificate outlining in reasonable detail the
computation of any amounts claimed by it under Section 2.4 or 2.5
and the assumptions underlying such computations, provided that
the failure to deliver a certificate shall not affect the Bank's
right to such amounts.

     2.7  Payments and Computations.  All amounts payable by the
Borrower to the Bank under this Agreement or the Note shall be
paid directly to the Bank in immediately available funds at the
address of the Bank set forth in Section 10.2 hereof or at such
other address of which the Bank shall give notice to the Borrower
pursuant to Section 10.2 hereof.  The Bank is authorized to
charge any account of the Borrower at the Bank for any payment
due by the Borrower under this Agreement or the Note.

Rate Loans hereunder shall be made by the Bank on the basis of a
year of 360 days for the actual number of days elapsed. 
Computation of interest hereunder with respect to Adjusted Base
Rate Loans hereunder shall be made by the Bank on the basis of a

     2.8  Borrowing.  The Borrower shall notify the Bank of each
proposed borrowing under the Line of Credit not later than
2:30 p.m., Philadelphia, Pennsylvania time on the day of the

with respect to Adjusted LIBO Rate Loans.

     2.9  Prepayment and Repayment.  Subject to Section 2.4 of

          The Bank may, and the Borrower authorizes the Bank to
debit the Borrower's accounts at the Bank for the amount of any
payment as and when such payment becomes due hereunder.  If there
are insufficient funds in such debited account at the time such
account is debited, and the debiting creates an overdraft, the

established from time to time by the Bank.  Such authorization
for the Bank to debit the Borrower's accounts at the Bank shall
not affect the Borrower's obligation to pay when due all amounts
payable hereunder, whether or not there are sufficient funds in
accounts of the Borrower.  The foregoing rights of the Bank to
debit the Borrower's accounts shall be in addition to, and not in
limitation of, any rights of set-off which the Bank may have

policies, certificates of insurance, riders and endorsements
relating to such insurance and proof of premium payments.  The
Borrower shall cause each hazard insurance policy to provide, and
the insurer issuing each such policy to certify to the Bank, that
(a) if such insurance be proposed to be canceled or materially

taxes, assessments, charges and levies forthwith whenever
foreclosure on any lien which attaches or security therefor
appears imminent.

     6.8  Leases.  Pay all rent or other sums required by every
lease to which the Borrower is a party as the same becomes due

things necessary to preserve and keep in full force and effect in

immediate notice to the Bank of (i) the existence of any dispute,
(ii) the institution of any litigation, administrative proceeding
or governmental investigation involving the Borrower or (iii) the

operation, financial condition, property or business of the
Borrower or affect the enforceability of this Agreement or any of
the other Loan Documents.

perform any of the conditions or covenants to be observed or
performed by it under this Agreement or any of the other loan
Documents.

trustee to administer any Plan, after the Borrower has notified

                      ARTICLE IX - REMEDIES

     9.1  Further Advances; Acceleration; Setoff.

          (a)  Upon the occurrence of any one or more Events of
Default, the Bank may, in its sole discretion, refuse to make any
further advances or Loans to the Borrower.

          (b)  Automatically upon the occurrence of any Event of
Default described in Section 8.7 of this Agreement, and in the
sole discretion of the Bank upon the occurrence of any other
Event of Default, the unpaid principal balance of all Loans, all
interest and fees accrued and unpaid thereon, and all other
amounts and Obligations payable by the Borrower under this
Agreement and the other Loan Documents shall immediately become
due and payable in full, all without protest, presentment,
demand, or further notice of any kind to the Borrower, all of
which are expressly waived by the Borrower.

          (c)  If any of the Obligations shall be due and payable
or any one or more Events of Default shall have occurred, the
Bank shall have the right, in addition to all other rights and
remedies available to it, without notice to the Borrower, to
apply toward and set-off against and apply to the then unpaid
balance of the Note and the other Obligations any items or funds
held by the Bank, any and all deposits (whether general or
special, time or demand, matured or unmatured, fixed or
contingent, liquidated or unliquidated) now or hereafter
maintained by the Borrower for its own account with the Bank, and
any other indebtedness at any time held or owing by the Bank to
or for the credit or the account of the Borrower.  For such
purpose the Bank shall have, and the Borrower hereby grants to
the Bank, a first lien on all such deposits.  The Bank is hereby
authorized to charge any such account or indebtedness for any
amounts due to the Bank.  Such right of set-off shall exist
whether or not the Bank shall have made any demand under this
Agreement, the Note or any other Loan Document and whether or not
the Note and the other Obligations are matured or unmatured.  The
Borrower hereby confirms the Bank's lien on such accounts and
right of set-off, and nothing in this Agreement shall be deemed
any waiver or prohibition of such lien and right of set-off.

     9.2  Further Remedies; Confession of Judgment.

          (a)  Upon the occurrence of any one or more Events of
Default, the Bank may proceed to protect and enforce its rights
under this Agreement and the other Loan Documents by exercising
such remedies as are available to the Bank in respect thereof
under applicable law, either by suit in equity or by action at
law, or both, whether for specific performance of any provision
contained in this Agreement or any of the other Loan Documents or
in aid of the exercise of any power granted in this Agreement or
any of the other Loan Documents.

          (b)  THE FOLLOWING PARAGRAPH SETS FORTH A POWER OF
AUTHORITY FOR ANY ATTORNEY TO CONFESS JUDGMENT AGAINST BORROWER. 
IN GRANTING THIS WARRANT OF ATTORNEY TO CONFESS JUDGMENT AGAINST
BORROWER, THE BORROWER, FOLLOWING CONSULTATION WITH (OR DECISION
NOT TO CONSULT) SEPARATE COUNSEL FOR BORROWER AND WITH KNOWLEDGE
OF THE LEGAL EFFECT HEREOF, HEREBY KNOWINGLY, INTENTIONALLY,
VOLUNTARILY, INTELLIGENTLY AND UNCONDITIONALLY WAIVES ANY AND ALL
RIGHTS THE BORROWER HAS OR MAY HAVE TO PRIOR NOTICE AND AN
OPPORTUNITY FOR HEARING UNDER THE RESPECTIVE CONSTITUTIONS AND
LAWS OF THE UNITED STATES OF AMERICA, COMMONWEALTH OF
PENNSYLVANIA, OR ELSEWHERE INCLUDING, WITHOUT LIMITATION, A
HEARING PRIOR TO GARNISHMENT AND ATTACHMENT OF THE BORROWER'S
BANK ACCOUNT AND OTHER ASSETS.  BORROWER ACKNOWLEDGES AND
UNDERSTANDS THAT BY ENTERING INTO THIS AGREEMENT CONTAINING A
CONFESSION OF JUDGMENT CLAUSE THAT BORROWER IS VOLUNTARILY,
INTELLIGENTLY AND KNOWINGLY GIVING UP ANY AND ALL RIGHTS,
INCLUDING CONSTITUTIONAL RIGHTS, THAT BORROWER HAS OR MAY HAVE TO
NOTICE AND A HEARING BEFORE JUDGMENT CAN BE ENTERED AGAINST
BORROWER AND BEFORE THE BORROWER'S ASSETS, INCLUDING, WITHOUT
LIMITATION, ITS BANK ACCOUNTS, MAY BE GARNISHED, LEVIED, EXECUTED
UPON AND/OR ATTACHED.  BORROWER UNDERSTANDS THAT ANY SUCH
GARNISHMENT, LEVY, EXECUTION AND/OR ATTACHMENT SHALL RENDER THE
PROPERTY GARNISHED, LEVIED, EXECUTED UPON OR ATTACHED IMMEDIATELY
UNAVAILABLE TO BORROWER.  IT IS SPECIFICALLY ACKNOWLEDGED BY
BORROWER THAT THE BANK HAS RELIED ON THIS WARRANT OF ATTORNEY AND
THE RIGHTS WAIVED BY BORROWER HEREIN IN ENTERING INTO THIS
AGREEMENT AND AS AN INDUCEMENT TO EXTEND CREDIT TO THE BORROWER.

          Upon the occurrence of an Event of Default hereunder or
under any other Loan Document, Borrower hereby jointly and
severally authorizes and empowers any attorney of any court of
record or the prothonotary or clerk of any county in the
Commonwealth of Pennsylvania, or in any jurisdiction where
permitted by law or the clerk of any United States District
Court, to appear for Borrower in any and all actions which may be
bought hereunder and enter and confess judgment against the
Borrower or any of them in favor of the Bank for such sums as are
due or may become due hereunder or under any other Loan
Documents, together with costs of suit and actual collection
costs including, without limitation, reasonable attorneys' fees
equal to 1% of the Obligations then due and owing but in no event
less than $5,000.00, with or without declaration, without prior
notice, without stay of execution and with release of all
procedural errors and the right to issue executions forthwith. 
To the extent permitted by law, Borrower waives the right of
inquisition on any real estate levied on, voluntarily condemns
the same, authorizes the prothonotary or clerk to enter upon the
writ of execution this voluntary condemnation and agrees that
such real estate may be sold on a writ of execution; and also
waives any relief from any appraisement, stay or exemption law of
any state now in force or hereafter enacted.  Borrower further
waives the right to any notice and hearing prior to the
execution, levy, attachment or other type of enforcement of any
judgment obtained hereunder, including, without limitation, the
right to be notified and heard prior to the garnishment, levy,
execution upon and attachment of Borrower's bank accounts and
other property.  If a copy of this Agreement verified by
affidavit of any officer of the Bank shall have been filed in
such action, it shall not be necessary to file the original
thereof as a warrant of attorney, any practice or usage to the
contrary notwithstanding.  The authority herein granted to
confess judgment shall not be exhausted by any single exercise
thereof, but shall continue and may be exercised from time to
time as often as the Bank shall find it necessary and desirable
and at all times until full payment of all amounts due hereunder
and under any other Loan Documents.  The Bank may confess one or
more judgments in the same or different jurisdictions for all or
any part of the Obligations arising hereunder or under any other
Loan Documents to which Borrower is a party, without regard to
whether judgment has theretofore been confessed on more than one
occasion for the same Obligations.  In the event that any
judgment confessed against the Borrower is stricken or opened
upon application by or on behalf of Borrower or any obligor for
any reason, the Bank is hereby authorized and empowered to again
appear for and confess judgment against Borrower for any part or
all of the Obligations owing under this Agreement and/or for any
other liabilities, as herein provided.

remedies of the Bank provided in this Agreement and the other
Loan Documents are cumulative and not exclusive of any right,
power or remedy provided by law or equity, and no failure or
delay on the part of the Bank in the exercise of any right,

dispute, claim or controversy arising out of, connected with or

arbitration provision does not apply to disputes under or related
to swap agreements. 

     10.9 Preservation and Limitation of Remedies.
Notwithstanding the preceding binding arbitration provisions,
Bank and Borrower agree to preserve, without diminution, certain
remedies that any party hereto may employ or exercise freely,
independently or in connection with an arbitration proceeding or
after an arbitration action is brought.  Bank and Borrower shall
have the right to proceed in any court of proper jurisdiction or
by self-help to exercise or prosecute the following remedies, as

personal property or other security by exercising a power of sale
granted under Loan Documents or under applicable law or by
judicial foreclosure and sale, including a proceeding to confirm
the sale; (ii) all rights of self-help including peaceful
occupation of real property and collection of rents, set-off, and
peaceful possession of personal property; (iii) obtaining
provisional or ancillary remedies including injunctive relief,
sequestration, garnishment, attachment, appointment of receiver
and filing an involuntary bankruptcy proceeding; and (iv) when
applicable, a judgment by confession of judgment.  Preservation
of these remedies does not limit the power of an arbitrator to
grant similar remedies that may be requested by a party in a
Dispute.

Borrower and Bank agree that they shall not have a remedy of
punitive or exemplary damages against the other in any Dispute
and hereby waive any right or claim to punitive or exemplary
damages they have now or which may arise in the future in
connection with any Dispute whether the Dispute is resolved by
arbitration or judicially.

     10.10  Governing Law.  This Agreement shall be construed in
accordance with and governed by the internal laws of the
Commonwealth of Pennsylvania.

     10.11  Integration.  This Agreement and the other Loan
Documents constitute the sole agreement of the parties with
respect to the subject matter hereof and thereof and supersede
all oral negotiations and prior writings with respect to the
subject matter hereof and thereof.

     10.12  Amendment and Waiver.  No amendment of this
Agreement, and no waiver of any one or more of the provisions
hereof shall be effective unless set forth in writing and signed
by the parties hereto.

     10.13  Successors and Assigns.

          (a)  Generally.  This Agreement (i) shall be binding
upon the Borrower and the Bank and their respective successors
and assigns, and (ii) shall inure to the benefit of the Borrower
and the Bank and their respective successors and assigns,
provided, however, that the Borrower may not assign its rights
hereunder or any interest herein without the prior written
consent of the Bank, and any such assignment or attempted
assignment by the Borrower shall be void and of no effect with
respect to the Bank.

          (b)  Participations.  The Bank may from time to time
sell or otherwise grant participations in the Loans and the Note,
provided that the Bank remains sole agent with respect to the
Loans and the Note, and the holder of any such participation, if
the participation agreement so provides, (i) shall, with respect
to its participation, be entitled to all of the rights of the
Bank and (ii) may exercise any and all rights of setoff or
banker's lien with respect thereto, in each case as fully as
though the Borrower were directly indebted to the holder of such
participation in the amount of such participation.  The Bank may
disclose to prospective participants such information regarding
the Borrower's affairs as the Bank possesses.  The Bank shall
give notice to the Borrower of the grant of such participations;
however, the failure to give such notice shall not affect any of
the Bank's rights hereunder.

     10.14  Severability of Provisions.  Any provision in this
Agreement that is held to be inoperative, unenforceable,
voidable, or invalid in any jurisdiction shall, as to that
jurisdiction, be ineffective, unenforceable, void or invalid
without affecting the remaining provisions, and to this end the
provisions of this Agreement are declared to be severable.

     10.15  Consent to Jurisdiction and Service of Process.  The
Borrower irrevocably appoints each and every officer of the
Borrower as its attorneys upon whom may be served, by regular or
certified mail at the address set forth in Section 10.2 hereof,
any notice, process or pleading in any action or proceeding
against it arising out of or in connection with this Agreement or
any of the other Loan Documents; and the Borrower hereby
(i) consents that any action or proceeding against it be
commenced and maintained in any court within the Commonwealth of
Pennsylvania or in the United States District Court for the
Eastern District of Pennsylvania by service of process on any
such officer; (ii) agrees that the courts of the Commonwealth of
Pennsylvania and the United States District Court for the Eastern
District of Pennsylvania shall have jurisdiction with respect to
the subject matter hereof and the person of the Borrower and the
Collateral, and (iii) waives any objection that such Borrower may
now or hereafter have as to the venue of any such suit, action or
proceeding brought in such a court or that such court is an
inconvenient forum.  Notwithstanding the foregoing, the Bank, in
its absolute discretion may also initiate proceedings in the
courts of any other jurisdiction in which the Borrower may be
found or in which any of its properties or the Collateral may be
located.

     10.16  Indemnification.

          (a)  If, after receipt of any payment of all or any
part of the Obligations, the Bank is compelled to surrender such
payment to any Person or entity for any reason (including,
without limitation, a determination that such payment is void or
voidable as a preference or fraudulent conveyance, an
impermissible setoff, or a diversion of trust funds), then this
Agreement and the other Loan Documents shall continue in full
force and effect, and the Borrower shall be liable for, and shall
indemnify, defend and hold harmless the Bank with respect to the
full amount so surrendered.

          (b)  The Borrower shall indemnify, defend and hold
harmless the Bank with respect to any and all claims, expenses,
demands, losses, costs, fines or liabilities of any kind,
including reasonable attorneys' fees and costs, arising from or
in any way related to (i) acts or conduct of the Borrower under,
pursuant to or related to this Agreement and the other Loan
Documents, (ii) Borrower's breach or violation of any
representation, warranty, covenant or undertaking contained in
this Agreement or the other Loan Documents, and (iii) Borrower's
failure to comply with any or all laws, statutes, ordinances,
governmental rules, regulations or standards, whether federal,
state, or local, or court or administrative orders or decrees,
including without limitation those resulting from any Hazardous
Materials or dangerous environmental condition within, on, from,
related to or affecting any real property owned or occupied by
the Borrower, unless resulting from the acts or conduct of the
Bank constituting gross negligence or willful misconduct.

          (c)  The provisions of this section shall survive the
termination of this Agreement and the other Loan Documents and
shall be and remain effective notwithstanding the payment of the
Obligations, the cancellation of the Note, the release of any
Encumbrance securing the Obligations or any other action which
the Bank may have taken in reliance upon its receipt of such
payment.  Any cancellation of the Note, release of any
Encumbrance or other such action shall be deemed to have been
conditioned upon any payment of the Obligations having become
final and irrevocable.

     IN WITNESS WHEREOF, the undersigned have caused this
Agreement to be executed by their duly authorized officers on the
date first above written.

          Section 1.1  Description of Debentures.

               (a)  The Company has authorized the issue and sale
of $4,000,000 aggregate principal amount of its 12% Subordinated

per annum, payable quarterly by automatic debit on the first day
of each February, May, August and November in each year

"Debentures" as used herein shall include each Debenture
delivered pursuant to this Agreement.  The terms which are
capitalized herein shall have the meanings set forth in Section

               (b)  Simultaneously with the purchase and sale of

   ARTICLE II - REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to Purchaser
as follows:

               Section 2.1  Corporate Status.

               (a)  The Company is a corporation duly organized,
validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and has the corporate power to own
and operate its properties, to carry on its business as now
conducted and to enter into and to perform its obligations under
this Agreement, the Debentures, the Preferred Stock Purchase
Agreement, the Warrant, the Registration Rights Agreement, the
Subordination Agreement between First Union National Bank, the
Company, and Purchaser, and any other document executed and
delivered by Purchaser in connection herewith or therewith
(collectively, the "Operative Documents").  The Company is
qualified to do business and is in good standing in each state or
other jurisdiction in which such qualification is necessary under
applicable provisions of law, except where the failure to so
qualify would not have a material adverse effect on the financial
condition or results of operations of the Company.  The states or
other jurisdictions in which the Company is so qualified are set
forth on Schedule 2.1(a) hereto.  A certified charter of the
Company and a good standing certificate for each state in which
it is qualified to do business are attached to Schedule 2.1(a).

               (b)  Schedule 2.1(b) sets forth a complete list of
each corporation, partnership, joint venture, limited liability
company or other business organization in which the Company owns,
directly or indirectly, any capital stock or other equity
interest (the "Subsidiary" or, collectively, the "Subsidiaries"),
or with respect to which the Company or any Subsidiary, alone or
in combination with others, is in a control position, which list
shows the jurisdiction of incorporation or other organization and
the percentage of stock or other equity interest of each
Subsidiary owned by the Company.  Each Subsidiary is duly
organized, validly existing and in good standing under the laws
of the jurisdiction of incorporation or other organization as
indicated on Schedule 2.1(b), each has all requisite power and
authority and holds all material licenses, permits and other
required authorizations from government authorities necessary to
own its properties and assets and to conduct its business as it
is now being conducted, and is qualified to do business as a
foreign corporation (or business organization) and is in good
standing in every jurisdiction in which such qualification is
necessary under applicable provisions of law, except where the
failure to so qualify would not have a material adverse effect on
the financial condition or results of operations of the Company. 
All of the outstanding shares of capital stock, or other equity
interest, of each Subsidiary owned, directly or indirectly, by
the Company have been validly issued, are fully paid and
nonassessable, and are owned by the Company free and clear of all
liens, charges, security interests or encumbrances.  A certified
charter for each Subsidiary and good standing certificates for
each of the states in which each Subsidiary is qualified to do
business are attached to Schedule 2.1(b).

               (c)  Schedule 2.1(c) sets forth a complete list of
"affiliates," as that term is defined in Rule 405 of Regulation C
adopted under the Securities Act of 1933, as amended (the
"Securities Act"), with a brief statement describing the basis of
each affiliation.

          Section 2.2  Capitalization.

               (a)  The authorized capital stock of the Company
consists of (i) 10,000,000 shares of common stock, par value
$.10 per share (the "Common Stock"), of which 2,962,784 shares
are issued and outstanding, and (ii) 1,000,000 shares of
undesignated preferred stock, with rights and preferences fixed
by the Board of Directors in accordance with the corporate laws
of the Commonwealth of Pennsylvania and the Company's Articles 
of Incorporation, none of which are outstanding.  All shares of
Common Stock outstanding have been validly issued and are fully
paid and nonassessable. There are no statutory or contractual
pre-emptive rights, rights of first refusal, antidilution rights
or any similar rights held by any party with respect to the
issuance of the Debentures.  The offer, sale and issuance of the
Debentures do not require registration under the Securities Act
or any applicable state securities laws.

          On October 1, 1996, the Thai Trade Arbitration Council

trade dispute with the Royal Thai Air Force ("RTAF").  If the
Company completes services to be performed under its contract
with RTAF by June 30, 1997, the Company will be entitled to
payment of approximately $450,000 from RTAF.  If the Company
completes the contract and receives at least $400,000 of amounts
due, the Company may use such amount to prepay the bridge notes
made by the Company in favor of (a) William F. Mitchell dated
February 7, 1997, in the principal amount of $300,000,

without the prior written consent of Purchaser.

          Section 5.3  Payment of Debentures.

perform all of the other obligations of the Company under this
Agreement.

          Section 5.4  Repurchase of Debenture.

          Neither the Company nor any Subsidiary or Affiliate,
directly or indirectly, may repurchase or make any offer to
repurchase any Debentures unless the offer has been made to
repurchase Debentures, pro rata, from all holders of the
Debentures at the same time and upon the same terms.  In case the
Company repurchases or otherwise acquires any Debentures, such
Debentures shall immediately thereafter be canceled, and no
Debentures shall be issued in substitution therefor.  Without
limiting the foregoing, upon the purchase or other acquisition of
any Debentures by the Company or any Subsidiary or Affiliate,
such Debentures shall no longer be outstanding for purposes of
any Section of this Agreement relating to the taking by the
holders of the Debentures of any actions with respect hereto,
including, without limitation, Sections 7.3 and 8.1.

          Section 5.5  Corporate Existence, Etc.

          The Company will preserve and keep in force and effect,
and will cause each Subsidiary to preserve and keep in force and
effect, its corporate existence and good standing in the state of
incorporation thereof, its qualification and good standing as a
foreign corporation in each jurisdiction where such qualification
is required by applicable law except where the failure to so
qualify would not have a material adverse effect on the financial
condition or results of operations of the Company and its
Subsidiaries, taken as a whole, and all licenses and permits
necessary to the proper conduct of its business.

          Section 5.6  Maintenance, Etc.

          The Company will maintain, preserve and keep, and will
cause each Subsidiary to maintain, preserve and keep, its
properties and assets which are used or useful in the conduct of
its business (whether owned in fee or pursuant to a leasehold
interest) in good repair and working order and from time to time
will make all necessary repairs, replacements, renewals and
additions so that at all times the efficiency thereof shall be
maintained.

          Section 5.7  Nature of Business.

          Neither the Company nor any Subsidiary will engage in
any business if, as a result, the general nature of the business,
taken on a consolidated basis, which would then be engaged in by
the Company and its Subsidiaries would be substantially changed
from the general nature of the business engaged in by the Company
and its Subsidiaries on the date of this Agreement.

          Section 5.8  Insurance.

          The Company will maintain, and will cause each
Subsidiary to maintain, insurance coverage by financially sound
and reputable insurers with respect to their respective
properties and business in such forms and amounts and against
such risks, casualties and contingencies as are customary for
corporations of established reputation engaged in the same or a
similar business and owning and operating similar properties.

          Section 5.9  Taxes, Claims for Labor and Materials.

          The Company will promptly pay and discharge, and will
cause each Subsidiary promptly to pay and discharge, (i) all
lawful taxes, assessments and governmental charges or levies
imposed upon the property or business of the  Company or such
Subsidiary, respectively, (ii) all trade accounts payable in
accordance with usual and customary business terms, and (iii) all
claims for work, labor or materials, which if unpaid might become
a lien or charge upon any property of the Company or such
Subsidiary; provided the Company or such Subsidiary shall not be
required to pay any such tax, assessment, charge, levy, account
payable or claim if (i) the validity, applicability or amount
thereof is being contested in good faith by appropriate actions
or proceedings which will prevent the forfeiture or sale of any
property of the Company or such Subsidiary or any material
interference with the use thereof by the Company or such
Subsidiary, and (ii) the Company or such Subsidiary shall set
aside on its books, reserves deemed by it to be adequate with
respect thereto.

          Section 5.10  Compliance with Laws.

          Except where failure to do so does not and would not
constitute a Material Adverse Event, The Company shall maintain
its business operations and property owned or used in connection
therewith in compliance with (i) all applicable federal, state
and local laws, regulations and ordinances, and such laws,
regulations and ordinances of foreign jurisdictions, governing
such business operations and the use and ownership of such
property, and (ii) all agreements, licenses, franchises,
indentures and mortgages to which The Company is a party or by
which The Company or any of its properties is bound.  Without
limiting the foregoing, The Company shall pay all of its
indebtedness promptly and substantially in accordance with the
terms thereof.

          Section 5.11  ERISA Matters.

          If the Company has in effect, or hereafter institutes,
a pension plan that is subject to the requirements of Title IV of
the Employee Retirement Income Security Act of 1974, Pub. L.

following covenants shall be applicable during such period as any
such plan (the "Plan") shall be in effect: (i)  the Company
hereby covenants that throughout the existence of the Plan, the
Company's contributions under the Plan will meet the minimum
funding standards required by ERISA and the Company will not
institute a distress termination of the Plan; and (ii) the
Company covenants that it will send to Purchaser a copy of any
notice of a reportable event (as defined in ERISA) required by
ERISA to be filed with the Labor Department or the Pension
Benefit Guaranty Corporation, at the time that such notice is so
filed; provided, however, that the current violation of this
covenant as described in Schedule 2.30 shall not be a violation
of this Section 5.11 so long as such violation is cured within
ten (10) days of the date hereof.

          Section 5.12  Books and Records; Rights of Inspection.

          The Company will keep, and will cause each Subsidiary
to keep, proper books of record and account in which full and
correct entries will be made of all dealings or transactions of
or in relation to the business and affairs of the Company or such
Subsidiary, in accordance with generally accepted accounting
principles consistently maintained.  The Company shall permit a
representative of Purchaser to visit any of its properties and
inspect its corporate books and financial records, and will
discuss its accounts, affairs and finances with a representative
of Purchaser, during reasonable business hours, at all such times
as Purchaser may reasonably request.

Securities Act nor any state securities laws.  Each Debenture
issued pursuant to this Agreement shall bear a legend in
substantially the following form:

          THIS DEBENTURE HAS NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY
APPLICABLE STATE SECURITIES LAW AND MAY NOT BE TRANSFERRED UNLESS
(i) THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE

any Debenture, by acceptance thereof, agrees, prior to any
transfer of such Debenture, to give written notice to the Company
of such holder's intention to effect such transfer or conversion
and briefly describing the manner of the proposed transfer.  Such
notice of intended transfer shall be accompanied by, if
applicable, a copy of the opinion of counsel to such holder
reasonably satisfactory to the Company, to the effect that
registration under the Securities Act of such Debenture, in
connection with such proposed transfer, is not required.  If in
the opinion of such counsel, the proposed transfer of such
Debenture, may be effected without registration of such
Debenture, under the Securities Act, such holder shall be
entitled to transfer such Debenture in accordance with the terms
of the notice delivered by such holder to the Company.  The
Company will promptly upon such transfer deliver new Debentures
not bearing a legend of the character set forth in Section 8.1,
unless in the opinion of such counsel subsequent disposition by
such holder may require registration under the Securities Act. 
If the proposed transfer of such Debenture may not be affected
without registration of such Debenture under the Securities Act,
the holder thereof shall not be entitled to transfer such
Debenture in the absence of an effective registration statement.

holders of at least 50% in aggregate principal amount of
outstanding Debentures; provided that without the written consent
of the holders of all of the Debentures then outstanding, no such
waiver, modification, alteration or amendment shall be effective
(a) which will change the time of payment of the principal of or
the interest on any Debenture or reduce the principal amount
thereof or change the rate of interest thereon, (b) which will
change any of the provisions with respect to optional
prepayments, or (c) which will change the percentage of holders
of the Debentures required to consent to any such amendment,
modification or waiver of any of the provisions of this
Article VIII or Article VII.

or additional  interest, fee or otherwise, to any holder of the
Debentures as consideration for or as an inducement to the
entering into by any holder of the Debentures of any waiver or
amendment of any of the terms and provisions of this Agreement
unless such remuneration is concurrently paid, on the same terms,
ratably to the holders of all of the Debentures then outstanding.

          Section 9.3  Effect of Amendment or Waiver.

          Any such amendment or waiver shall apply equally to all
of the holders of the Debentures and shall be binding upon them,

such amendment or waiver.  No such amendment or waiver shall
extend to or affect any obligation not expressly amended or
waived or impair any right consequent thereon.

     NOW, THEREFORE, in mutual consideration of the premises and
the respective representations, warranties, covenants and
agreements contained herein, the parties agree as follows:

             ARTICLE I. - SALE AND PURCHASE OF STOCK

     Section 1.1.  Description of Preferred Stock.

     The Company has authorized the issue and sale of 25,000

the Company's Statement With Respect to Shares attached as
Exhibit A (the "Statement With Respect to Shares") hereto for a
purchase price of $100 per share, or an aggregate purchase price
of $2,500,000.00.  The Statement With Respect to Shares shall be

capitalized herein shall have the meanings set forth in Section 8
hereof unless the context shall otherwise require.

     Section 1.2.  Commitment; Closing Date.

     Subject to the terms and conditions hereof and on the basis
of the representations and warranties hereinafter set forth, the

Stock for an aggregate purchase price of $2,500,000.

     Delivery of a single certificate representing the Preferred

   ARTICLE II. - REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company hereby represents and warrants to Purchaser as
follows:

     Section 2.1.  Corporate Status.

          (a)  The Company is a corporation duly organized,
validly existing and in good standing under the laws of the
Commonwealth of Pennsylvania and has the corporate power to own
and operate its properties, to carry on its business as now
conducted and to enter into and to perform its obligations under
this Agreement, the Registration Rights Agreement between the
Company and Purchaser dated of even date herewith (the
"Registration Rights Agreement") and any other document executed
and delivered by Purchaser in connection herewith or therewith
(collectively, the "Operative Documents").  The Company is
qualified to do business and is in good standing in each state or
other jurisdiction in which such qualification is necessary under
applicable provisions of law; except where the failure to so
qualify would not have a material adverse effect on the financial
condition or result of operations of the Company.  The states or
other jurisdictions in which the Company is so qualified are set
forth on Schedule 2.1(a) hereto.  A certified charter of the
Company and a good standing certificate for each state in which
it is qualified to do business are attached to Schedule 2.1(a).

          (b)  Schedule 2.1(b) sets forth a complete list of each
corporation, partnership, joint venture, limited liability
company or other business organization in which the Company owns,
directly or indirectly, any capital stock or other equity
interest (the "Subsidiary" or, collectively, the "Subsidiaries"),
or with respect to which the Company or any Subsidiary, alone or
in combination with others, is in a control position, which list
shows the jurisdiction of incorporation or other organization and
the percentage of stock or other equity interest of each
Subsidiary owned by the Company.  Each Subsidiary is duly
organized, validly existing and in good standing under the laws
of the jurisdiction of incorporation or other organization as
indicated on Schedule 2.1(b), each has all requisite power and
authority and holds all material licenses, permits and other
required authorizations from government authorities necessary to
own its properties and assets and to conduct its business as it
is now being conducted, and is qualified to do business as a
foreign corporation (or business organization) and is in good
standing in every jurisdiction in which such qualification is
necessary under applicable provisions of law; except where the
failure to so qualify would not have a material adverse effect on
the financial condition or results of operations of the company. 
All of the outstanding shares of capital stock, or other equity
interest, of each Subsidiary owned, directly or indirectly, by
the Company have been validly issued, are fully paid and
nonassessable, and are owned by the Company free and clear of all
liens, charges, security interests or encumbrances.  A certified
charter for each Subsidiary and good standing certificates for
each of the states in which each Subsidiary is qualified to do
business are attached to Schedule 2.1(b).

          (c)  Schedule 2.1(c) sets forth a complete list of
"affiliates," of the Company as that term is defined in Rule 405
of Regulation C adopted under the Securities Act of 1933, as
amended (the "Securities Act"), with a brief statement describing
the basis of each affiliation.

     Section 2.2.  Capitalization.
     
          (a)  The authorized capital stock of the Company
consists of (i) 10,000,000 shares of common stock, par value $.10
per share, of which 2,962,784 shares are issued and outstanding,
and (ii) 1,000,000 shares of undesignated preferred stock, with
rights and preferences to be fixed by the Board of Directors in
accordance with the corporate laws of the Commonwealth of
Pennsylvania and the Company's Articles of Incorporation, and of
which, as of the Closing, 25,000 shall have been designated as
"Series A Convertible Preferred Stock," bearing the rights,
preferences and limitations set forth in the Statement With
Respect to Shares and none of which are outstanding.  All shares
of Common Stock outstanding have been validly issued and are
fully paid and nonassessable.  There are no statutory or
contractual pre-emptive rights, rights of first refusal,
antidilution rights or any similar rights held by any party with
respect to the issuance of the Preferred Stock.  The offer, sale
and issuance of the Preferred Stock do not require registration
under the Securities Act or any applicable state securities laws.

          (b)  The Company has not granted, or agreed to grant or
issue, any options, warrants or rights to purchase or acquire
from the Company any shares of capital stock of the Company, and
there are no securities outstanding which are convertible into or
exchangeable for shares of Common Stock, or contracts,
commitments, agreements, understandings, arrangements or
restrictions as to which the Company is a party, or by which it
is bound, relating to any shares of capital stock or other
securities of the Company, whether or not outstanding except for
(i) the conversion privileges of the Preferred Stock to be issued
pursuant to this Agreement, with respect to which 416,666.67
shares of Common Stock have been reserved for issuance upon
conversion, (ii) 314,164 shares of Common Stock reserved for
issuance pursuant to the Company's 1988 Stock Option Plan, for
which options to purchase 99,010 shares are outstanding, (iii) a
warrant to acquire 100,000 shares of Common Stock held by Chase
Manhattan Capital Corporation, and (iv) the obligation to issue
to Osprey Partners, in certain circumstances, a warrant to
purchase 125,000 shares of Common Stock.  Schedule 2.2 sets forth
a summary of such options, warrants and other rights to acquire
capital stock of the Company.

          (c)  The Preferred Stock that is being purchased by the
Purchaser, when issued, sold, and delivered in accordance with
the terms of this Agreement for the consideration expressed
herein, will be duly and validly issued, fully paid, and
nonassessable, and will be free of restrictions on transfer other
than restrictions on transfer under this Agreement and under
applicable state and federal securities laws.  The Common Stock
issuable upon conversion of the Preferred Stock being purchased
under this Agreement has been duly and validly reserved for
issuance and, upon issuance in accordance with the terms of the
Statement With Respect to Shares and this Agreement, will be duly
and validly issued, fully paid, and nonassessable and will be
free of restrictions on transfer other than restrictions on
transfer under this Agreement and under applicable state and
federal securities laws.

     Section 2.3.  Authorization.

     The Company has full legal right, power and authority to
enter into and perform its obligations under this Agreement and
any of the other Operative Documents, without the consent or
approval of any other person, firm, governmental agency or other
legal entity.  The execution and delivery of this Agreement and
the Operative Documents, the issuance of the Preferred Stock
hereunder, the execution and delivery of each other document in
connection herewith or therewith to which the Company is a party,
and the performance by the Company of its obligations hereunder
and/or thereunder are within the corporate powers of the Company
and have been duly authorized by all necessary corporate action
properly taken, have received all necessary governmental
approvals, if any were required.  The consummation of the
transactions contemplated by this Agreement and the fulfillment
of the terms hereof do not and will not contravene or conflict
with the Articles of Incorporation or Bylaws of the Company or
any material agreement to which the Company or any of its
Subsidiaries is now a party or by which any of them or their
properties is bound, or constitute a default thereunder; or
results in the creation or imposition of any lien, charge,
security interest, or encumbrance of any nature upon any of the
property or assets of the Company or any of its Subsidiaries
pursuant to the terms of any such agreement or instrument; or
violates any provision of law or any applicable judgment,
ordinance, regulation or order of any court or governmental
agency.  The officer(s) executing this Agreement, the Operative
Documents and any other document executed and delivered by
Purchaser in connection herewith or therewith, is duly authorized
to act on behalf of the Company.

     Section 2.4.  Validity and Binding Effect.

     Each of the Operative Documents is the legal, valid and
binding obligation of the Company, enforceable against the
Company in accordance with its terms.

     Section 2.5.  Contracts and Other Commitments.

     Except as disclosed on Schedule 2.5, the Company and its
Subsidiaries do not have and are not bound by any contract,
agreement, lease, commitment, loans, liens, pledges, security
interests upon which the Company or any Subsidiary is obligated
or by which the Company is bound other than (i) contracts for the
purchase of supplies and services that were entered into in the
ordinary course of business and that do not involve more than
$50,000, and do not extend for more than one (1) year beyond the
date hereof, (ii) sales contracts entered into in the ordinary
course of business, and (iii) contracts terminable at will by the
Company on more than thirty (30) days' notice without cost or
liability to the Company and that do not involve any employment
or consulting arrangement and are not material to the conduct of
the Company's business.  Consummation of the transactions hereby
contemplated and the performance of the obligations of the
Company under and by virtue of the Operative Documents will not
result in any breach of, or constitute a default under, any
material mortgage, security deed or agreement, deed of trust,
lease, bank loan or credit agreement, or any corporate articles,
certificate or bylaws, agreement or certificate of limited
partnership, partnership agreement, limited liability company
agreement, license, franchise or any other material instrument or
agreement to which the Company is a party or by which the Company
or its properties may be bound or, to the knowledge or the
Company, affected or to which the Company has not obtained an
effective waiver.

     Section 2.6.  Litigation.

     Except as set forth on Schedule 2.6, there is no litigation,
arbitration, claim, proceeding or investigation pending or
threatened in writing in which the Company or any Subsidiary is a
party or to which any of its respective properties or assets is
the subject which, if determined adversely to the Company or such
Subsidiary, would individually or in the aggregate have a
material adverse effect on the financial position, results of
operations or business of the Company and its Subsidiaries, taken
as a whole.

     Section 2.7.  Financial Statements.

     The consolidated financial statements of the Company and its
Subsidiaries for the fiscal years ended February 25, 1994,
February 24, 1995, and February 23, 1996, and the unaudited
consolidated financial statements as of the nine (9) months ended
November 29, 1996, which the Company previously has heretofore
delivered to Purchaser, fairly present the financial condition of
the Company and its Subsidiaries as at the effective dates of and
for the periods referred to in such financial statements and have
been prepared in accordance with generally accepted accounting
principles ("GAAP") consistently followed throughout the periods
involved.  The consolidated balance sheets and the related notes
fairly present the financial condition of the Company and its
consolidated Subsidiaries as of the respective dates thereof, and
the consolidated statements of income, cash flows and changes in
stockholders' equity and the related notes fairly present the
results of operations of the Company and its consolidated
Subsidiaries for the respective periods indicated.  There has
been no material adverse change in the condition, financial or
otherwise, of the Company and its Subsidiaries taken as a whole
since November 29, 1996.

     Section 2.8.  SEC Reports.

     The Company's Common Stock is listed on the American Stock
Exchange and has been duly registered with the Securities and
Exchange Commission ("SEC") under the Securities Exchange Act of
1934, as amended (the "Exchange Act")].  Since February 26, 1993,
the Company has filed all reports, registrations, proxy or
information statements and all other documents, together with any
amendments required to be made thereto, required to be filed with
the SEC under the Securities Act and the Exchange Act
(collectively, the "SEC Reports").  Since February 26, 1995, the
Company has timely filed all SEC Reports.  The financial
statements contained in the SEC Reports fairly presented the
financial position of the Company as of the dates mentioned and
the results of operations, changes in stockholders' equity and
changes in financial position or cash flows for the periods then
ended in conformity with GAAP applied on a consistent basis
throughout the periods involved.  The Company previously has
furnished to Purchaser true copies of all the SEC Reports,
together with all exhibits thereto that Purchaser has requested. 
As of their respective dates, the SEC Reports complied (or will
comply, as the case may be) in all material respects with all
rules and regulations promulgated by the SEC and did not (or will
not, as the case may be) contain any untrue statement of a
material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were
made, not misleading.

     Section 2.9.  Absence of Changes.

     Since November 29, 1996, (i) neither the Company nor any of
its Subsidiaries have incurred any liabilities or obligations,
direct or contingent, or entered into any transactions, not in
the ordinary course business, that are material to the Company,
(ii) neither the Company nor any of its Subsidiaries have
purchased any of its outstanding capital stock or declared, paid
or otherwise made any dividend or distribution of any kind on its
capital stock, (iii) there has not been any change in the capital
stock, long-term debt or short-term debt of the Company, and
(iv) there has not been any material adverse change, or any
development involving a prospective material adverse change, in
or affecting the condition (financial or otherwise), results of
operations, business or prospects of the Company or any
Subsidiary, taken as a whole.

     Section 2.
     Except as set forth on Schedule 2.10 and except where a
default or event of default does not and would not constitute a
Material Adverse Event, no default or event of default by the
Company or any Subsidiary exists under this Agreement or any of
the other Operative Documents, or under any other instrument or
agreement to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or its respective properties
may be bound or, to the knowledge of the Company, affected, and
no event has occurred and is continuing that with notice or the
passage of time or both would constitute a default or event of
default thereunder.

     Section 2.11.  Compliance With Law.

     To the Company's knowledge, the Company is in compliance
with all laws, regulations, decrees and orders applicable to it
(including but not limited to laws, regulations, decrees and
orders relating to environmental, occupational and health
standards and controls, antitrust, monopoly, restraint of trade
or unfair competition) to the extent that noncompliance, in the
aggregate, cannot reasonably be expected to cause a Material
Adverse Event.

     Section 2.12.  Taxes.

     Except as set forth on Schedule 2.12, the Company and its
Subsidiaries have filed or caused to be filed all federal, state
and local income, excise and franchise tax returns required to be
filed (except for returns that have been appropriately extended),
and has paid, or provided for the payment of, all taxes shown to
be due and payable on said returns and all other taxes,
impositions, assessments, fees or other charges imposed on it by
any governmental authority, agency or instrumentality, prior to
any delinquency with respect thereto (other than taxes,
impositions, assessments, fees and charges currently being
contested in good faith by appropriate proceedings, for which
appropriate amounts have been reserved), and the Company does not
know of any proposed assessment for additional taxes or any basis
therefor.  No tax liens have been filed against the Company or
any of its properties.  The Company's federal income tax
liability has been finally determined by the Internal Revenue
Service and satisfied for all taxable years up to and including
the taxable year ended February 24, 1995 or closed by applicable
statutes of limitation.

     Section 2.13.  Certain Transactions.

     Except as set forth on Schedule 2.13(i) and except as to
indebtedness incurred in the ordinary course of business and
approved by the Board of Directors of the Company, neither the
Company nor any Subsidiary is indebted, directly or indirectly,
to any of its officers or directors, or to their respective
spouses or children, in excess of an aggregate amount of $60,000,
and none of the officers or directors or any members of their
immediate families are indebted to the Company or any Subsidiary
in excess of an aggregate amount of $60,000 or have any direct or
indirect ownership interest in any firm or corporation with which
the Company or any Subsidiary is affiliated or with which the
Company has a business relationship, or any firm or corporation
which competes with the Company or any Subsidiary, except that
officers and/or directors of the Company may own no more than 1%
of the outstanding stock of any publicly traded company which
competes directly with the Company.  Except as set forth on
Schedule 2.13(ii), no officer or director of the Company or any
Subsidiary or any member of their immediate families is, directly
or indirectly, interested in any material contract with the
Company.  Except as set forth on Schedule 2.13(iii), neither the
Company nor any Subsidiary is a guarantor or indemnitor of any
indebtedness of any other person, firm or corporation.

     Section 2.14.  Title to Property.

     The Company and each Subsidiary has good and marketable
title to all of real and material personal property owned by it,
free and clear of all liens, security interests, pledges,
encumbrances, equities claims and restrictions of every kind and
nature whatsoever, except as disclosed on Schedule 2.14 and
except for such liens, security interests, pledges, encumbrances,
equities claims and restrictions which are not in the aggregate
material to the business, operations or financial condition of
the Company and its Subsidiaries taken as a whole.  Any real

                                                  Exhibit 10.9


THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"), OR ANY APPLICABLE STATE SECURITIES
LAW AND MAY NOT BE TRANSFERRED UNTIL (I) A REGISTRATION STATEMENT
UNDER THE ACT AND SUCH APPLICABLE STATE SECURITIES LAWS SHALL
HAVE BECOME EFFECTIVE WITH REGARD THERETO, OR (II) IN THE OPINION
OF COUNSEL ACCEPTABLE TO THE COMPANY, REGISTRATION UNDER THE ACT
AND SUCH APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED IN
CONNECTION WITH SUCH PROPOSED TRANSFER.

                     STOCK PURCHASE WARRANT

          This Warrant is issued this 27th day of March, 1997, by
ENVIRONMENTAL TECTONICS CORPORATION, a Pennsylvania corporation
(the "Company"), to SIRROM CAPITAL CORPORATION, a Tennessee
corporation (SIRROM CAPITAL CORPORATION and any subsequent
assignee or transferee hereof are hereinafter referred to
collectively as "Holder" or "Holders").

                           AGREEMENT:

          1.   Issuance of Warrant; Term.  For and in
consideration of SIRROM CAPITAL CORPORATION purchasing from the
Company its debenture due March 27, 2004, in the initial
principal amount of Four Million and no/100ths Dollars (the
"Debenture") pursuant to the terms of a Debenture Purchase
Agreement of even date herewith (the "Debenture Purchase
Agreement"), and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the
Company hereby grants to Holder the right to purchase
166,410 shares of the Company's common stock, par value $.10 per
share (the "Common Stock"), which the Company represents to equal
five percent (5%) of the shares of capital stock outstanding on
the day immediately prior to the date hereof, calculated on a
fully diluted basis, excluding the shares of Common Stock
issuable upon conversion of the Series A Convertible Preferred
Stock of the Company issued and sold to Sirrom Capital
Corporation on the date hereof and assuming exercise of this
Warrant ("Base Amount").  The shares of Common Stock issuable
upon exercise of this Warrant are hereinafter referred to as the
"Shares."  This Warrant shall be exercisable at any time and from
time to time from the date hereof until March 27, 2004.

          2.   Exercise Price.  The exercise price (the "Exercise
Price") per share for which all or any of the Shares may be
purchased pursuant to the terms of this Warrant shall be One
Dollar ($1.00).

          3.   Exercise.  This Warrant may be exercised by the
Holder hereof (but only on the conditions hereinafter set forth)
as to all or any increment or increments of one hundred (100)
Shares (or the balance of the Shares if less than such number),
upon delivery of written notice of intent to exercise to the
Company at the following address:  125 James Way, Southampton, PA
18966-3877 or such other address as the Company shall designate
in a written notice to the Holder hereof, together with this
Warrant and payment to the Company of the aggregate Exercise
Price of the Shares so purchased.  The Exercise Price shall be
payable, at the option of the Holder, (i) by certified or bank
check, (ii) by the surrender of the Debenture or portion thereof
having an outstanding principal balance equal to the aggregate
Exercise Price or (iii) by the surrender of a portion of this
Warrant where the Shares subject to the portion of this Warrant
that is surrendered have a Fair Market Value (as defined in
Section 4(c) below) equal to the aggregate Exercise Price.  Upon
exercise of this Warrant as aforesaid, the Company shall as
promptly as practicable, and in any event within fifteen (15)
days thereafter, execute and deliver to the Holder of this
Warrant a certificate or certificates for the total number of
whole Shares for which this Warrant is being exercised in such
names and denominations as are requested by such Holder.  If this
Warrant shall be exercised with respect to less than all of the
Shares, the Holder shall be entitled to receive a new Warrant
covering the number of Shares in respect of which this Warrant
shall not have been exercised, which new Warrant shall in all
other respects be identical to this Warrant.  The Company
covenants and agrees that it will pay when due any and all state
and federal issue taxes which may be payable in respect of the
issuance of this Warrant or the issuance of any Shares upon
exercise of this Warrant.

          4.   Covenants and Conditions.  The above provisions
are subject to the following:

               (a)  Neither this Warrant nor the Shares have been
registered under the Securities Act of 1933, as amended
("Securities Act") or any state securities laws ("Blue Sky
Laws").  This Warrant has been acquired for investment purposes
and not with a view to distribution or resale and may not be sold
or otherwise transferred without (i) an effective registration
statement for such Warrant under the Securities Act and such
applicable Blue Sky Laws, or (ii) an opinion of counsel, which
opinion and counsel shall be reasonably satisfactory to the
Company and its counsel, that registration is not required under
the Securities Act or under any applicable Blue Sky Laws (the
Company hereby acknowledges that Sherrard & Roe, PLC is
acceptable counsel).  Transfer of the shares issued upon the
exercise of this Warrant shall be restricted in the same manner
and to the same extent as the Warrant and the certificates
representing such Shares shall bear substantially the following
legend:

               THE SHARES OF COMMON STOCK
               REPRESENTED BY THIS CERTIFICATE
               HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED
               (THE "ACT"), OR ANY APPLICABLE
               STATE SECURITIES LAW AND MAY NOT BE
               TRANSFERRED UNTIL (I) A
               REGISTRATION STATEMENT UNDER THE
               ACT AND SUCH APPLICABLE STATE
               SECURITIES LAWS SHALL HAVE BECOME
               EFFECTIVE WITH REGARD THERETO, OR
               (II) IN THE OPINION OF COUNSEL
               ACCEPTABLE TO THE COMPANY,
               REGISTRATION UNDER SUCH ACT AND
               SUCH APPLICABLE STATE SECURITIES
               LAWS IS NOT REQUIRED IN CONNECTION
               WITH SUCH PROPOSED TRANSFER.

The Holder hereof and the Company agree to execute such other
documents and instruments as counsel for the Company reasonably
deems necessary to effect the compliance of the issuance of this
Warrant and any shares of Common Stock issued upon exercise
hereof with applicable federal and state securities laws.

               (b)  The Company covenants and agrees that all
Shares which may be issued upon exercise of this Warrant will,
upon issuance and payment therefor, be legally and validly issued
and outstanding, fully paid and nonassessable, free from all
taxes, liens, charges and preemptive rights, if any, with respect
thereto or to the issuance thereof.  The Company shall at all
times reserve and keep available for issuance upon the exercise
of this Warrant such number of authorized but unissued shares of
Common Stock as will be sufficient to permit the exercise in full
of this Warrant.

               (c)  The Company covenants and agrees that it
shall not sell any shares of the Company's capital stock at a
price per share below the Fair Market Value of such shares,
without the prior written consent of the Holder hereof  except
pursuant to exercise of (i) options outstanding as of the date
hereof, (ii) options granted subsequent to the date hereof
provided, however, the exercise price of such options is no less
than the Fair Market Value of the Common Stock at the date of the
grant, or (iii) the warrant for the purchase of 100,000 shares of
Common Stock currently held by Chase Manhattan Capital
Corporation.  In the event that the Company sells shares of the
Company's capital stock in violation of this Section 3(c), the
number of shares issuable upon exercise of this Warrant shall be
equal to the product obtained by multiplying the number of shares
issuable pursuant to this Warrant prior to such sale by the
quotient obtained by dividing (i) the Fair Market Value of the
shares issued in violation of this Section 3(c) by (ii) the price
at which such shares were sold.

               (d)  "Fair Market Value" per share of Common Stock
shall mean (i) in the case of a security listed or admitted to
trading on any securities exchange, the last reported sale price,
regular way (as determined in accordance with the practices of
such exchange), on such day, or if no sale takes place on such
day, the average of the closing bid and asked prices on such day
(and in the case of a security traded on more than one national
securities exchange, at such price or such average, upon the
exchange on which the volume of trading during the last calendar
year was the greatest), (ii) in the case of a security not then
listed or admitted to trading on any securities exchange, the
last reported sale price on such day, or if no sale takes place
on such day, the average of the closing bid and asked prices on
such day, as reported by a reputable quotation service designated
by the Company, (iii) in the case of a security not then listed
or admitted to trading on any securities exchange and as to which
no such reported sale price or bid and asked prices are
available, the average of the reported high bid and low asked
prices on such day, as reported by a reputable quotation service,
or the Wall Street Journal, or if there are no bids and asked
prices on such day, the average of the high bid and low asked
prices, as so reported, on the most recent day (not more than 30
days prior to the date in question) for which prices have been so
reported, and (iv) in the case of a security determined by the
Company's Board of Directors as not having an active quoted
market or in the case of other property, such fair market value
as shall be determined by the Board of Directors.  The
determination as to whether any fractional shares are issuable
shall be based upon the total number of shares of  Preferred
Stock being converted at any one time by any holder thereof, not
upon each share of  Preferred Stock being converted.

               (e)  In the event that the Company, pursuant to
the terms of that certain letter agreement dated July 28, 1994,
between the Company and Osprey Partners ("Osprey"), grants to
Osprey a warrant to purchase 125,000 shares of the Common Stock,
then the number of Shares as to which this Warrant initially is
exercisable shall be increased by 6,250 shares, subject to
further adjustment as provided herein.

          5.   Transfer of Warrant.  Subject to the provisions of
Section 3 hereof, this Warrant may be transferred, in whole or in
part, to any person or business entity, by presentation of the
Warrant to the Company with written instructions for such
transfer; provided, however, that this Warrant shall not be
transferred without the prior written consent of the Company to
either of Wyle Labs or Latecoere or to any entity that controls,
is controlled by, or is under common control with either of Wyle
Labs or Latecoere.  Upon such presentation for transfer, the
Company shall promptly execute and deliver a new Warrant or
Warrants in the form hereof in the name of the assignee or
assignees and in the denominations specified in such
instructions.  The Company shall pay all expenses incurred by it
in connection with the preparation, issuance and delivery of
Warrants under this Section.

          6.   Warrant Holder Not Shareholder; Rights Offering;
Preemptive Rights.  Except as otherwise provided herein, this
Warrant does not confer upon the Holder, as such, any right
whatsoever as a shareholder of the Company.  Notwithstanding the
foregoing, if the Company should offer to all of the Company's
shareholders the right to purchase any securities of the Company,
then all shares of Common Stock that are subject to this Warrant
shall be deemed to be outstanding and owned by the Holder and the
Holder shall be entitled to participate in such rights offering. 
The Company shall not grant any preemptive rights with respect to
any of its capital stock without the prior written consent of the
Holder.

          7.   Observation Rights.  A nominee of the holder of
that portion of this Warrant representing a majority of
underlying shares shall receive notice of and be entitled to
attend or may send a representative to attend all meetings of the
Company's Board of Directors in a non-voting observation capacity
and shall receive a copy of all correspondence and information
delivered to the Company's Board of Directors, from the date
hereof until such time as the indebtedness evidenced by the
Debenture has been paid in full; provided, however, that this
requirement shall be deemed satisfied so long as a nominee of the
original purchaser of the Debenture is a director of the Company.

          8.   Adjustment Upon Changes in Stock.  

               (a)  If all or any portion of this Warrant shall
be exercised subsequent to any stock split, stock dividend,
recapitalization, combination of shares of the Company, or other
similar event, occurring after the date hereof, then the Holder
exercising this Warrant shall receive, for the aggregate price
paid upon such exercise, the aggregate number and class of shares
which such Holder would have received if this Warrant had been
exercised immediately prior to the record date for such stock
split, stock dividend, recapitalization, combination of shares,
or other similar event.  If any adjustment under this Section
8(a), would create a fractional share of Common Stock or a right
to acquire a fractional share of Common Stock, such fractional
share shall be disregarded and the number of shares subject to
this Warrant shall be the next higher number of shares, rounding
all fractions upward.  Whenever there shall be an adjustment
pursuant to this Section 8(a), the Company shall forthwith notify
the Holder or Holders of this Warrant of such adjustment, setting
forth in reasonable detail the event requiring the adjustment and
the method by which such adjustment was calculated.

               (b)  If all or any portion of this Warrant shall
be exercised subsequent to any merger, consolidation, exchange of
shares, separation, reorganization or liquidation of the Company,
or other similar event, occurring after the date hereof, as a
result of which shares of Common Stock shall be changed into the
same or a different number of shares of the same or another class
or classes of securities of the Company or another entity, or the
holders of Common Stock are entitled to receive cash or other
property, then the Holder exercising this Warrant shall receive,
for the aggregate price paid upon such exercise, the aggregate
number and class of shares, cash or other property which such
Holder would have received if this Warrant had been exercised
immediately prior to such merger, consolidation, exchange of
shares, separation, reorganization or liquidation, or other
similar event.  If any adjustment under this Section 8(b) would
create a fractional share of Common Stock or a right to acquire a
fractional share of Common Stock, such fractional share shall be
disregarded and the number of shares subject to this Warrant
shall be the next higher number of shares, rounding all fractions
upward.  Whenever there shall be an adjustment pursuant to this
Section 8(b), the Company shall forthwith notify the Holder or
Holders of this Warrant of such adjustment, setting forth in
reasonable detail the event requiring the adjustment and the
method by which such adjustment was calculated.

          9.   Certain Notices.  In case at any time the Company
shall propose to:

               (a)  declare any cash dividend upon its Common
Stock;

               (b)  declare any dividend upon its Common Stock
payable in stock or make any special dividend or other
distribution to the holders of its Common Stock;

               (c)  offer for subscription to the holders of any
of its Common Stock any additional shares of stock in any class
or other rights;

               (d)  reorganize, or reclassify the capital stock
of the Company, or consolidate, merge or otherwise combine with,
or sell of all or substantially all of its assets to, another
corporation;

               (e)  voluntarily or involuntarily dissolve,
liquidate or wind up of the affairs of the Company; or

               (f)  redeem or purchase any shares of its capital
stock or securities convertible into its capital stock;

then, in any one or more of said cases, the Company shall give to
the Holder of the Warrant, by certified or registered mail,
(i) at least twenty (20) days' prior written notice of the date
on which the books of the Company shall close or a record shall
be taken for such dividend, distribution or subscription rights
or for determining rights to vote in respect of any such
reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up, and (ii) in the case of
such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, at least twenty
(20) days' prior written notice of the date when the same shall
take place.  Any notice required by clause (i) shall also
specify, in the case of any such dividend, distribution or
subscription rights, the date on which the holders of Common
Stock shall be entitled thereto, and any notice required by
clause (ii) shall specify the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such
reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up, as the case may be.

Management's Discussion and Analysis of
Financial Condition and Results of Operations
($ in Thousands, except per share amounts)

Results of Operations

Fiscal 1997 Versus Fiscal 1996

     Fiscal 1997 sales increased 40% over fiscal 1996 sales as
significant increases in Aircrew Training Systems products and
the Sterilizers segment were only partially offset by a decrease
in the Environmental line (for information concerning business
segments, see Note 10 to the consolidated financial statements).

     Cost of goods sold as a percentage of sales increased to 74%
from 67% in fiscal 1996.  Overall, this increase primarily
reflected the write-down of $556 of certain slow-moving products
primarily in the Aircrew Training Systems segment, $143 of
additional depreciation expense for a demonstrator unit
transferred from inventory to fixed assets, $284 related to the
Company's outstanding claim with the U.S. Navy, including an
arbitration award in late April 1997 to one of the Company's
subcontractors in the Navy CFET project for various work
performed in the building part of the project, and $109 of
additional amortization expense relating to capitalized software
costs of a certain product.  The Company continues to actively
market the slow-moving items.  The Company is currently reviewing
the arbitration costs as well as additional expenditures made
through October 1996 on the CFET project to determine which, if
any, will be added to the existing claims against the U.S.
Government.

     The Aircrew Training Systems segment reported a
significantly higher sales level, up $5,209, or 65%, as a result
of continuing production on certain large contracts and a further
expansion of the Company's Contractor Operator and Maintenance
(COMS) business.  As has been reported, the Company's backlog in
the Aircrew Training systems segment has grown significantly in
the most recent period, reflecting, to some extent, a
stabilization of the world defense market.  However, despite the
sales increase, operating income decreased, reflecting a portion
of the aforementioned inventory write-downs, depreciation and
amortization expense and arbitration award as well as a larger
allocated share of the selling, general and administrative pool
of expenses.

     Sales in the Sterilizers segment increased $1,451, or 30%,
reflecting the completion of certain larger contracts coupled
with increased service and spare parts activity.  Operating
performance was a profit of $151 versus a loss in the prior
period.  This profit resulted from the higher volume coupled with
a slight increase in the gross margin on a better mix of work and
only partially offset by the aforementioned inventory write-down.

     The Environmental Systems segment experienced both decreased
sales and a higher operating loss.  This segment experienced
lower bookings throughout the period coupled with higher costs on
certain products.  The Company has recently implemented personnel
and product changes to strengthen operating results.

Operating and Other Expenses

     Selling and administrative expenses in fiscal 1997 increased
$819 compared to the prior period but as a percent of sales
decreased to 20.0% from 22.8%.  Approximately 90% of the increase
was comprised of increased sales commissions, advertising and
trade shows, and accounting and legal fees.  The increase in
commissions reflected a greater mix of commissionable sales and
the increased sales activity.  Advertising, brochures and trade
show activity increased because the Company made a conscious
effort to expand its presence and influence via technical
publications, symposiums, etc.  Accounting and legal fees
increased as the Company evaluated its options for
recapitalization that was ultimately completed in March 1997. 
The increased costs were partially offset by lower salary expense
in the selling and administrative area despite the heightened
activity.

     Research and development expenditures increased slightly. 
The Company continues to monitor this activity tightly.

     Interest expense increased in fiscal 1997 over fiscal 1996. 
The increase reflected amortization in the current period of a
non-cash deferred finance charge ($202) associated with warrants
issued in conjunction with the Company's credit facility renewal
in February 1996 coupled with interest charges for federal and
state tax settlements.  Interest on bank borrowing decreased as a
result of lower average loan balances.

     Other expenses decreased, primarily reflecting reduced
foreign exchange and other fees.

Fiscal 1996 Versus Fiscal 1995

     Fiscal 1996 sales decreased from fiscal 1995 sales as
decreases in the Sterilizers and Environmental Systems segments
were only partially offset by increased sales in the Aircrew
Training Systems segment.  (For information concerning business
segments, see Note 10 to the consolidated financial statements.)

     Cost of goods sold as a percentage of sales decreased to 67%
from 75% in fiscal year 1995, primarily reflecting higher sales
in the Aircrew Training Systems segment (Aircrew Training Systems
sales historically reflect higher gross margins) coupled with the
continuing positive effects of stringent cost controls.

     The Aircrew Training Systems segment reported a
significantly increased operating income in fiscal 1996 versus
fiscal 1995, reflecting the aforementioned increased sales volume
(up 40% from the prior fiscal year).  Operating income in the
Aircrew Training Systems segment was also positively affected by
the continued expansion of the Company's COMS business which
involves training, operation and support at various operations
throughout the world.

     The Sterilizers segment incurred a higher operating loss in
fiscal 1996 versus fiscal 1995, reflecting the decreased sales
volume (down 32%), partially offset by reduced operating
expenses.

     The Environmental Systems segment realized a lower operating
loss in fiscal 1996 versus fiscal 1995 despite a 21% decrease in
sales volume.  Reduced operating income from the sales reduction
was offset by the completion of higher margin projects
domestically and the positive impact of reduced operating
expenses.

     International sales have been a significant portion of the
Company's business in recent years.  In fiscal 1996,
approximately 59% of the Company's sales represented foreign
sales.  International sales were spread across all business
segments in the 1996 fiscal period, representing 27% of the total
sales from the Sterilizers and Environmental Systems segments. 
Management believes that the international market will continue
to comprise a significant portion of the Company's new business
in the next fiscal year.

Operating and Other Expenses

     Selling and administrative expenses decreased in fiscal 1996
versus fiscal 1995.  The reduction resulted from a reduced number
of full-time equivalent employees in fiscal 1996 coupled with
continuing stringent cost controls.

     Research and development expenditures in fiscal 1996
decreased significantly from the prior period.  This primarily
reflected the completion in certain major contracts of the
development stage on new products, line extensions and software
design and the beginning of production upon the attainment of
technical feasibility.

     Interest expense increased in fiscal 1996 versus fiscal
1995, reflecting higher interest rates coupled with higher
interest amortization expense on long-term obligations, that were
only partially offset by a lower average loan balance.

     Letter of credit fees and other expenses both decreased in
the 1996 fiscal period compared to 1995, reflecting reduced bank
fees and loan amortization costs.

Liquidity and Capital Resources 

     At February 28, 1997, the Company had a revolving credit
facility with a bank (the "Old Credit Facility") that provided
financing of up to an aggregate of $7.7 million.  The facility
was due to expire on March 31, 1997.  

     In connection with the 1996 extension of the Old Credit
Facility to March 31, 1997, the Company issued to the bank
warrants to purchase 100,000 shares of the Company's common stock
at a price equal to $5.18.  The Company has agreed to file a
registration statement with the Securities and Exchange
Commission to register the common stock issuable upon exercise of
the warrants.  If the Registration Statement is not effective
prior to July 15, 1997, the Company will forfeit a $375,000
escrow to the bank.

     On March 27, 1997, the Company executed a revolving credit
agreement (the "Credit Agreement") with a new bank establishing a
credit facility of $10 million.  The facility bears interest at
the bank's prime rate and expires on May 31, 1999.  Substantially
all of the Company's short-term financing is provided by this
bank.  Additionally, the Company issued $4 million of
subordinated debentures, bearing interest at 12% per annum, due
March 27, 2004 to a financial investor.  In connection with the
subordinated debentures, warrants were issued to acquire 166,410
shares of the Company's common stock at an exercise price of
$1.00 per share.  $499 of the proceeds from the sale of the
debentures was allocated to the warrants and will be charged to
income over the term of the debentures.  The Company also issued
25,000 shares of 11%, $100 face value, convertible preferred
stock for $2.5 million.  Each share of preferred stock is
convertible, at the option of the shareholder, into 13.33 shares
of the Company's common stock at a price of $7.50 per share.

     The proceeds from these transactions were used to repay
amounts outstanding under the Old Credit Facility at February 28,
1997.

     Because of write-downs of certain inventory and other year-
end adjustments that resulted in the Company recognizing a net
loss of $20 for the fiscal year ended February 28, 1997, as of
June 6, 1997, the bank has made all credit availability under the
Credit Agreement subject to specific prior approval by the bank
pending a review of the Company's financial condition.  The
Company believes this restriction will be temporary.

     During fiscal 1997, the Company's net cash position
increased to $189 at February 28, 1997 from $31 at February 23,
1996.  Cash was used in operations due to a significant increase
in accounts receivable due to the increase in sales and a
decrease in the billings in excess of costs and estimated
earnings on uncompleted contracts as more jobs proceeded through
their production cycle.  The cash used in operations was offset
by the positive impact of non-cash expenditures and a significant
increase in customer deposits.

     Non-cash expenditures included fixed asset depreciation and
capitalized software ($1,215), amortization of deferred finance
charges associated with the aforementioned 1996 refinancing
($202), and an increase in receivable and inventory reserves
($769).  Customer deposits increased at year-end, reflecting a
significant level of fourth-quarter job bookings.

     Partial offsets to the increased cash flow were an increase
in accounts receivable ($3,755), reflecting a higher level of
sales in the fourth quarter, continued payments under two
settlement agreements ($530), and a decrease in billings in
excess of costs on uncompleted long-term contracts, as some
larger contracts entered the production cycle.

     Cash used in investing activities decreased as a result of
lower capitalization of software costs and fewer equipment
acquisitions.

     Cash from financing was positive.  The 1997 financing was
short-term loans from affiliated parties of $1,300, that more
than offset bank repayments of $775.

     The Company has recorded approximately $2.9 million in
unbilled costs subject to negotiation, which includes contract
costs through October 1995 and which may not be received in full
during fiscal 1998.  This amount includes claims made against the
U.S. Government involving a U.S. Navy gyrolab contract and a
large centrifuge contract.  Additionally, the Company is
currently reviewing expenditures through October 1996 on the Navy
centrifuge contract to determine which, if any, will be added to
the existing claims with the U.S. Government.  Such claims are
customary in U.S. Government contracts.  To the extent the
Company is unsuccessful in further recovering contract costs,
such an event could have a material adverse effect on the
Company's liquidity and results of operations.  Historically, the
Company has had good experience in that recoveries against the
U.S. Government have exceeded claims.

     During the year ended February 28, 1997, the Company's
principal sources of cash were customers' advance deposits and
loans from affiliates.  These funds were primarily used to
support an increase in accounts receivable, a reduction in
billings in excess of costs on long-term contracts, and
repayments under the bank line of credit.

Backlog

     The Company's sales backlog at February 28, 1997 and
February 23, 1996 for work to be performed and revenue to be
recognized under written agreements after such dates was
approximately $25.8 million and $20.9 million, respectively.  In
addition, the Company's training and maintenance contracts
backlog at February 28, 1997 and February 23, 1996 for work to be
performed and revenue to be recognized after that date under
written agreements was approximately $5.1 million and $2.1
million, respectively.  Of the 1997 backlog, approximately $21.9
million is under contracts for aircrew training systems and
maintenance support principally for U.S. (approximately $300) and
foreign governments (approximately $19.0 million).  The U.S.
Government contracts are subject to termination at the
convenience of the Government with equitable cancellation cost
recovery.  Approximately 80% of the 1997 backlog is expected to
be completed prior to February 27, 1998.  Subsequent to year-end,
on May 1, 1997 the Company announced receipt of the largest
contract in its 28-year history.  The Ministry of Defense of the
United Kingdom awarded the Company a $21.3 million contract for

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
($ in thousands, except per share amounts)

1.   Summary of Significant Accounting Policies:

     Nature of Business:

     The Company is primarily engaged in the development and
     manufacture of aircrew and disaster simulation training
     systems, sterilizers, and environmental systems. The Company
     focuses on product extension and new product development. 
     Sales of aircrew training systems are made principally to
     U.S. and foreign governmental agencies.  Sales of
     sterilizers and environmental systems are made to commercial
     and governmental entities worldwide.

     Principles of Consolidation:

     The consolidated financial statements include the accounts
     of Environmental Tectonics Corporation (the Company) and its
     wholly-owned subsidiary, ETC International Corporation.  All
     material intercompany accounts and transactions have been
     eliminated.  The Company's fiscal year is the 52- or 53-week
     annual accounting period ending the last Friday in February.

     Use of Estimates:

     In preparing financial statements in conformity with
     generally accepted accounting principles, management is
     required to make estimates and assumptions that affect the
     reported amounts of assets and liabilities and the
     disclosure of contingent assets and liabilities at the date
     of the financial statements and revenues and expenses during
     the reporting period.  Actual results could differ from
     those estimates.  Significant estimates include revenue
     recognition under the percentage of completion method (see
     Note 1, Revenue Recognition), claims receivable, inventory,
     and computer software costs.  

     The Company has recorded approximately $2.9 million in
     claims receivable for contract costs incurred through
     February 28, 1997 (see Note 2), which are subject to
     negotiation and audit by the U.S. and foreign governments. 
     To the extent the Company is unsuccessful in realizing these
     claims, there could be a material adverse effect on the
     Company's liquidity and results of operations.

     Subsequent to February 28, 1997, $284 was awarded to one of
     the Company's subcontractors in the Navy CFET project for
     various work performed in the building part of the project. 
     The Company is currently reviewing the arbitration costs as
     well as additional expenditures made through October 1996 on
     the CFET project to determine which, if any, will be added
     to the existing claims with the U.S. Government.

     Revenue Recognition:

     Revenue is recognized on long-term contracts utilizing the
     percentage of completion method based on costs incurred as a
     percentage of estimated total costs.  Revenue recognized on
     uncompleted long-term contracts in excess of amounts billed
     to customers is reflected as an asset.  Amounts billed to
     customers in excess of revenue recognized on uncompleted
     long-term contracts is reflected as a liability.  When it is
     estimated that a contract will result in a loss, the entire
     amount of the loss is accrued.  The effect of revisions in
     cost and profit estimates for long-term contracts is
     reflected in the accounting period in which the facts
     requiring the revisions become known.  The effect of
     revisions in estimates of contract revenues was to increase
     net loss before tax by approximately $406 and decrease net
     income before tax by approximately $83 in fiscal 1997 and
     1996, respectively.  Contract progress billings are based
     upon contract provisions for customer advance payments,
     contract costs incurred, and completion of specified
     contract objectives.  Contracts may provide for customer
     retainage of a portion of amounts billed until contract
     completion.  Retainage is generally due within one year of
     completion of the contract.  Revenue for service contracts
     is recognized ratably over the life of the contract; related
     material costs are expensed as incurred.

     Cash and Cash Equivalents:

     Cash and cash equivalents include short-term deposits at
     market interest rates with original maturities of three
     months or less.  The Company maintains cash balances at
     several financial institutions located in the Northeast. 
     Accounts in each institution are insured by the Federal
     Deposit Insurance Corporation up to $100.  Uninsured
     balances aggregate to $245 at February 28, 1997.

     Inventories:

     Inventories are valued at the lower of cost or market.  Cost
     is determined principally by the first-in, first-out method. 
     The costs of finished goods and work-in-process inventories
     include material, direct engineering, manufacturing labor,
     and overhead components.  The Company periodically reviews
     the inventory and, if necessary, writes down the recorded
     costs.  During the fourth quarter of fiscal year 1997, the
     Company determined that a write-down adjustment of
     approximately $556 was necessary on certain slow moving
     products.

     Depreciation of Property, Plant, and Equipment:

     Property, plant, and equipment are depreciated over their
     estimated useful lives by the straight-line method for
     financial reporting purposes.  Accelerated depreciation
     methods are used for tax purposes.  Upon sale or retirement
     of property, plant, and equipment, the costs and related
     accumulated depreciation are eliminated from the accounts. 
     Any resulting gains or losses are included in the
     determination of net income.  During the fourth quarter of
     1997, the Company transferred from inventory to fixed assets
     a demonstrator unit and recorded $143 of additional
     depreciation expense.

     Amortization of Capitalized Software Development Costs:

     The Company capitalizes the qualifying costs of developing
     software contained in certain products. Capitalization of
     costs requires that technological feasibility has been
     established.  When the software is fully documented and
     tested, capitalization of development costs cease and
     amortization commences over a period ranging from 36 to 60
     months (dependent upon the life of the product) on a
     straight-line basis which, at a minimum, approximates
     estimated sales.

     Realization of capitalized software costs is subject to the
     Company's ability to market the related product in the
     future and generate cash flows to support future operation.

     Capitalized software costs and related amortization 
     totalled $494 and $681 for the year ended February 28, 1997. 
     Capitalized software costs and related amortization totalled
     $696 and $573 during the year ended February 23, 1996.
     During 1997, the Company reevaluated the amortization period
     of costs associated with a certain product and, as a result,
     an additional $109 was expensed during the fourth quarter of
     1997.

     Amortization of Deferred Financing Costs:

     Capitalized costs relating to the acquisition of the
     Company's credit facility are amortized over the term of the
     credit facility.  Amortization expense relating to deferred
     financing costs was $202 and $3 in 1997 and 1996,
     respectively.

     Amortization of Discount on Settlement Payable:

     The discount on settlement payable related to a products
     liability settlement, the liability that was recognized in
     fiscal 1996, is amortized over the term of the note. 
     Amortization expense was $34 and $55 in fiscal 1997 and
     1996, respectively.

     Income Taxes:

     The Company accounts for income taxes using the liability
     method, which reflects the impact of temporary differences
     between values recorded for assets and liabilities for
     financial reporting purposes and values utilized for
     measurement in accordance with tax laws.

     Long-Lived Assets:

     The Company has adopted Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of
     Long-Lived Assets and for Long-Lived Assets to Be Disposed
     Of," which provides guidance on when to recognize and how to
     measure impairment losses of long-lived assets and certain
     identifiable intangibles and how to value long-lived assets
     to be disposed of.  The adoption of SFAS No. 121 had no
     material effect on the Company's consolidated financial
     position or results of operations.

     Stock Options:

     The Company has adopted SFAS No. 123, "Accounting for Stock-
     Based Compensation," which contains a fair value-based
     method for valuing stock-based compensation that entities
     may use, which measures compensation cost at the grant date
     based on the fair value of the award.  Compensation is then
     recognized over the service period, which is usually the
     vesting period.  Alternatively, the standard permits
     entities to continue accounting for employee stock options
     and similar instruments under Accounting Principles Board
     (APB) Opinion No. 25, "Accounting for Stock Issued to
     Employees."  Entities that continue to account for stock
     options using APB Opinion No. 25 are required to make pro
     forma disclosures of net income and earnings per share, as
     if the fair value-based method of accounting defined in SFAS
     No. 123 had been applied.  The Company's Incentive Stock
     Option Plan is accounted for under APB Opinion No. 25.

     Advertising and Trade Shows Costs:

     The Company expenses advertising costs as incurred. 
     Advertising and trade show expense was $189 and $83 for the
     years ended February 28, 1997 and February 23, 1996,
     respectively.

     (Loss) Earnings Per Common Share:

     (Loss) earnings per common share in 1997 and 1996 are based
     on net income divided by the weighted average number of
     common shares and common stock equivalent shares (shares
     issuable upon the exercise of stock purchase warrants and
     options, unless anti-dilutive) outstanding.  The weighted
     average number of common shares and common stock equivalent
     shares outstanding was 2,965,000 and 2,935,000 in 1997 and
     1996, respectively.

     The Financial Accounting Standards Board has issued SFAS
     No. 128, "Earnings Per Share," which is effective for
     financial statements issued after December 15, 1997.  The
     new standard eliminates primary and fully diluted earnings
     per share and requires presentation of basic and diluted
     earnings per share together with disclosure of how the per
     share amounts were computed.  Basic earnings per share
     excludes dilution and is computed by dividing income
     available to common shareholders by the weighted average
     common shares outstanding for the period.  Diluted earnings
     per share reflects the potential dilution that could occur
     if securities or other contracts to issue common stock were
     exercised and converted into common stock or resulted in the
     issuance of common stock that then shared in the earnings of
     the entity.  Due to the antidilutive effect resulting from
     the loss, the adoption of this standard will not effect
     earnings per share for the year ended February 28, 1997.

     Reclassifications:

     Certain reclassifications have been made to the 1996
     financial statements to conform with the 1997 presentation.

2.   Accounts Receivable:

     The components of accounts receivable at February 28, 1997
     and February 23, 1996 are as follows:

                                                 1997     1996 

      U.S. Government receivables billed and
        unbilled contract costs subject to
        negotiation                             $ 5,284  $ 3,848

      U.S. commercial receivables billed          2,477      746
      International receivables billed            3,828    3,240
                                                 11,589    7,834
      Less allowance for doubtful accounts         (237)    (124)

                                                $11,352  $ 7,710


     U.S. Government receivables billed and unbilled contract
     costs subject to negotiation:

     Unbilled contract costs subject to negotiation represent
     claims made or to be made against the U.S. Government under
     a contract for a centrifuge.  These costs were recorded
     during fiscal years 1994 and 1995.  The Company has recorded
     claims, amounting to $2.6 million, to the extent of contract
     costs incurred. These costs have been incurred in connection
     with U.S. Government-caused delays, errors in specifications
     and designs, and other unanticipated causes and may not be
     received in full during fiscal 1998.  In accordance with
     generally accepted accounting principles, revenue recorded
     by the Company from a claim does not exceed the incurred
     contract costs related to the claim.  The Company currently
     has approximately $8.6 million in claims filed with the U.S.
     Government.  The U.S. Government has responded to the claims
     with either denials or deemed denials which the Company has
     appealed.  Additionally, the Company is now reviewing
     expenditures from November 1995 through October 1996 to
     determine what, if any, additional amounts can be filed as a
     supplemental claim.  Such claims are subject to negotiation
     and audit by the U.S. Government.

     In November 1996, the Company invoiced the balance due under
     the centrifuge contract; at February 28, 1997, approximately
     $1.7 million was included in U.S. Government receivables.

     Collectibility of these amounts may be dependent upon the
     resolution of the above claims.

     International receivables billed:

     International receivables billed includes $1.3 million
     related to an arbitration award resulting from certain
     claims made against a foreign government (see Note 12).

</TABLE>
     (a)  At February 28, 1997, the Company had a revolving
          credit facility with a bank which provided financing of
          up to an aggregate of $7.7 million, expiring on
          March 31, 1997.  The proceeds from the credit facility
          were utilized to provide working capital financing and
          to support the issuance of letters of credit.  The
          credit facility included certain covenants related to,
          among other things, prohibitions on the payment of cash
          dividends, minimum tangible net worth requirements, and
          various financial ratios. The credit facility is
          collateralized by substantially all assets of the
          Company.

          Direct borrowings under the credit facility were
          limited to the lesser of $7.5 million or the Company's
          borrowing base as calculated pursuant to the terms of
          the agreement (approximately $7.8 million borrowing
          base at February 28, 1997).  The letter of credit
          sublimit was $7 million.  At February 28, 1997, there
          were $665 letters of credit outstanding (of which
          approximately $464 were cash collateralized), exclusive
          of a $1.1 million letter of credit for the RTAF which
          was drawn against in the first quarter of fiscal 1995
          (see Note 12).  Interest is charged on direct
          borrowings at the bank's prime rate plus 2.0%.  The
          interest rate was 10.25% at February 28, 1997 and
          February 23, 1996.  The Company was required to pay a
          commitment fee of 0.5% per annum on the average unused
          balance.  Fees on letters of credit outstanding were
          2.0% per year.

          The approximate average loan balance, maximum aggregate
          borrowings outstanding at any month-end payable to
          banks during the fiscal years, and weighted average
          interest rate computed by the days outstanding method
          are as follows:

          As a condition to the issuance of the original credit
          facility, warrants to purchase 100,000 shares of the
          Company's common stock at $5.00 per share were issued
          on November 20, 1990.  These warrants expired on
          November 20, 1995.  As a condition to the extension of
          the credit facility through March 31, 1997, warrants
          were issued to purchase 100,000 shares of the Company's
          common stock at a price equal of $5.18.  The warrants
          will be exercisable through 2001.  If the holder
          desires to sell or transfer any of its warrants, the
          Company has the right of first refusal.  A deferred
          charge of $202 was assigned to the warrants and
          amortized to profit and loss during the year ended
          February 28, 1997.  Warrants issued provide for
          adjustments of the exercise price and the number of
          shares issuable thereunder in the event that the
          Company issues additional shares of common stock or
          rights to purchase common stock at a price less than
          the current warrant price or current market price,
          whichever is greater.  The Company has agreed to file a
          registration statement with the Securities and Exchange
          Commission to register the common stock issuable upon
          exercise of the warrants.  If the Registration
          Statement is not effective prior to July 15, 1997, the
          Company will forfeit a $375 escrow to the bank.

          On March 27, 1997, the Company executed an agreement
          (the "Credit Agreement") with a bank establishing a
          revolving credit facility of $10 million through
          May 31, 1998, at which time the facility is reduced to
          $9 million.  The facility bears interest at the bank's
          base rate or adjusted Libor and expires on May 31,
          1999.  The credit facility includes certain covenants
          related to, among other things, prohibitions on
          incurring additional debt, change in ownership of
          certain officers, payment of dividends and certain
          financial ratio requirements.  The credit facility is
          collateralized by substantially all of the assets of
          the Company.  

          Because of write-downs of certain inventory and other
          year-end adjustments that resulted in the Company
          recognizing a net loss of $20 for the fiscal year ended
          February 28, 1997, as of June 6, 1997, the bank has
          made all credit availability under the Credit Agreement
          subject to specific prior approval by the bank pending
          a review of the Company's financial condition.  The
          Company believes this restriction will be temporary.

          Additionally, the Company issued $4 million of
          subordinated debentures, bearing interest at 12% per
          annum, due March 27, 2004.  In connection with the
          subordinated debentures, warrants were issued to
          acquire 166,410 shares of the Company's common stock at
          an exercise price of $1.00 per share; proceeds from the
          debentures will be allocated to the warrants and
          charged to income over the term of the debentures.  The
          Company also issued 25,000 shares of 11%, $100 face
          value, convertible preferred stock for $2.5 million. 
          Each share of preferred stock is convertible, at the
          option of the shareholder, into 13.33 shares of the
          Company's common stock at a price of $7.50 per share.  

          The proceeds from these transactions were used to repay
          amounts outstanding under the existing credit facility
          at February 28, 1997.  Accordingly, the current amounts
          refinanced have been reclassified as long-term
          obligations.  

     (b)  During June 1995, the Company entered into a settlement
          with the employee of a customer who brought a products
          liability claim against the Company.  The settlement of
          $1,195 will be satisfied with (i) funds of $547
          (including accrued interest) previously deposited by
          the Company's products liability insurance carrier with
          the U.S. District Court, and (ii) a settlement payable
          to the plaintiff for the remaining amount of $648.  The
          Company paid $53 by July 20, 1995 and $100 on April 20,
          1996.  In September 1996, the Company renegotiated the
          payment schedule.  For the period from October 1996 to
          September 1997, the Company will pay $10 per month. 
          Beginning October 1997, the Company will pay $5 per
          month until the obligation is satisfied.  The claimant
          did reserve the right to pursue additional payment
          amounts as per the original settlement agreement of
          July 29, 1995.  The Company has recorded a discount of
          $207 on this settlement based on an imputed interest
          rate of 11%, which will be amortized over the term of
          the settlement.

     The amount of long-term obligations maturing in each of the
     next five fiscal years is $95 in 1998; $60 in 1999; $60 in
     2000; $60 in 2001; $60 in 2002; and $80 thereafter.  

7.   Notes Payable - Related Parties:

     Notes payable of $1.3 million represent amounts due from
     directors, executive officers and their affiliates.  Notes
     payable, due January 1, 1998, bear interest at 10% and are
     subordinated to the Company's credit facility.  The payees
     have the right to convert the notes into shares of the
     Company's common stock.  The notes are convertible into
     approximately 108,000 shares, at a price of $12, if
     converted on or before June 30, 1997.  After June 30, 1997,
     the notes can be converted at a price which is the greater
     of $5 or 75% of the average closing price of the Company's
     common stock. Subsequent to year-end, the Company repaid
     $500 of the outstanding notes payable.

8.   Leases:

     Operating Leases:

     The Company leases certain premises and office equipment
     under operating leases which expire over the next five
     years.  Future minimum rental payments required under
     noncancellable operating leases having a remaining term
     expiring after one fiscal year as of February 28, 1997 are
     $18 in 1998; $15 in 1999; $14 in 2000; $12 in 2001; and $2
     in 2002.

     Total rental expense for all operating leases for the years
     ended February 28, 1997 and February 23, 1996 was
     approximately $197 and $219, respectively.

10.  Business Segment Information:

     The Company primarily manufactures, under contract, various
     types of high technology equipment which it has also
     designed and developed.  A significant portion of the
     equipment is sold directly or through distributors to
     foreign markets.  Except for the foreign sales activity and
     certain operations and maintenance contracts, all operations
     of the Company are conducted in the United States. 
     Information on the Company's industry segments is as

<PAGE>
10.  Business Segment Information (Continued):

     Operating income (loss) consists of net sales less
     applicable costs and expenses relating to these revenues.
     General corporate expenses, letter of credit fees, interest
     expense, other expenses, and income taxes have been excluded
     from the determination of segment operating income (loss). 
     General corporate expenses are primarily central
     administrative office expenses.  Property, plant, and
     equipment and, accordingly, depreciation and capital
     expenditures are not identifiable with specific business
     segments because most of these assets are used in each of
     the segments.

     Approximately 17% and 11% of sales in 1997 were made to two
     international customers, totalling sales of $3,826 and
     $2,527, respectively, in the Aircrew Training Systems
     segment.  Approximately 15% of sales in 1996 were made to
     one international customer, totalling sales of $2,366 in the
     Aircrew Training Systems segment.

     Included in the segment information for the year ended
     February 28, 1997 are export sales of approximately $15,422. 
     Of these amounts, there are sales to or relating to the
     Governments of United Kingdom ($3,826), Japan ($2,527),
     China ($1,969), Tunisia ($684) and Egypt ($483) for the sale
     of the Aircrew Training Systems segment.  Sales to the U.S.
     Government and its agencies aggregate approximately $2,082
     for the year ended February 28, 1997.

     Included in the segment information for the year ended
     February 23, 1996 are export sales of approximately $9,198. 
     Of these amounts, there are sales to or relating to the
     Governments of Japan ($559), Bangladesh ($602) and the
     United Kingdom ($2,366) for the sale of Aircrew Training
     equipment.  Sales to the U.S. Government and its agencies
     aggregate approximately $1,631 for the year ended
     February 23, 1996.

11.  Stock Options:

     The Company has a fixed Incentive Stock Option Plan (the
     Plan) accounted for under APB Opinion No. 25 and related
     Interpretations.  The Plan allows the Company to grant
     options to employees for up to 500,000 shares of common
     stock and will terminate on August 24, 1998.  The options,
     which have a term of 10 years when issued, vest over a four-
     year period.  The exercise price of each option shall not be
     less than 100% of the current market price of the Company's
     stock on the date of grant.  Accordingly, no compensation
     cost has been recognized for the Plan.  Had compensation
     cost for the Plan been determined based on the fair value of
     the options at the grant dates consistent with the method of
     SFAS No. 123, the Company's net income and earnings per
     share would have been reduced to the pro forma amounts
     indicated below.

</TABLE>
     The fair value of each option grant is estimated on the date
     of grant using the Black-Scholes options-pricing model with
     the following weighted average assumptions used for grants
     in 1997: dividend yield of 0%; expected volatility of 60%;
     risk-free interest rate of 6.2%%; and expected life of four
     years.

     A summary of the status of the Plan as of February 28, 1997
     and February 23, 1996, and changes during the years ending
     on those dates is presented below.

12.  Claims and Litigation:

     In October 1993, the Company was notified by the Royal Thai
     Air Force ("RTAF") that the RTAF was terminating a certain
     $4.6 million simulator contract with the Company.  Although
     the Company had performed in excess of 90% of the contract,
     the RTAF alleged a failure to completely perform.  In
     connection with this termination, the RTAF made a call on a
     $229 performance bond, as well as a draw on approximately
     $1.1 million of advance payment letters of credit.  Work
     under this contract had stopped while under arbitration, but
     on October 1, 1996, the Thai Trade Arbitration Counsel
     rendered its decision under which the contract was
     reinstated in full and the Company was given a period of
     nine months to complete the remainder of the work.  Upon
     completion of the contract, the RTAF will pay the Company
     the open receivables balance, consisting of the performance
     bond and the advance payment, plus the 10% due on the
     balance of the contract.  Except as noted in the award, the
     rights and obligations of the parties remain as per the
     original contract.  Should the Company fail to perform under
     the contract in the time period allotted, the RTAF could
     invoke penalties against the Company, including termination
     of the contract and delay penalties.  Based on the progress
     to date and recent discussions with the RTAF, the Company
     estimates it will probably exceed the nine-month contract
     completion period due to an extended delay in obtaining an
     export license for certain hardware required to complete the
     job.  This license has been cleared and the hardware is in
     the country.  The Company has submitted a request for a
     contract extension under the "force majeure" clause of the
     RTAF contract, and the customer has agreed to an extension
     to complete the installation and training. 

     A lawsuit was commenced against the Company in April 1997 in
     the United States District Court for the District of Puerto
     Rico by an employee of a customer who claims to have been
     injured as a result of an alleged malfunction of a
     sterilizer manufactured by the Company.  The plaintiff is
     seeking $3 million in damages.  The Company has up to $10
     million of products liability coverage, subject to a $100
     deductible.  The outcome of this litigation is not currently
     predictable.

     Certain other claims, suits, and complaints arising in the
     ordinary course of business have been filed or are pending
     against the Company.  In the opinion of management, after
     consultation with legal counsel, all such matters are
     reserved for or adequately covered by insurance or, if not
     so covered, are without merit or are of such kind, or
     involve such amounts, as would not have a significant effect
     on the financial position or results of operations of the
     Company if disposed of unfavorably.

13.  Related Party Transactions:

     The Company transacts certain business in Europe through
     Environmental Tectonics Corporation (Europe) Ltd., (ETC
     Europe), an affiliated entity which is 99% owned by the
     president of the Company.  ETC Europe provides certain
     marketing and administrative services relating to European
     sales and maintenance contracts.  Administrative fees paid
     to ETC Europe were approximately $45 and $80 for the years
     ended February 28, 1997 and February 23, 1996, respectively.

14.  Employee Benefit Plan

     The Company maintains a retirement savings 401(k) plan for
     eligible employees.  The Company's contributions to the plan
     are based on a percentage of the employees' qualifying
     contributions.  The Company's contributions totalled $83 and
     $88 in 1997 and 1996, respectively.

     From time to time, the Company had not made employee
     contribution payments to the trustee of its employee benefit
     plan concurrent with payroll payments to such employees. 
     The Company is now making these payments concurrent with its
     payroll.  By reason of such past late payments, the Company
     may be subject to certain additional interest and taxes as
     well as potential penalties.

Board of Directors
Environmental Tectonics Corporation


     We have audited the accompanying consolidated balance sheets
of Environmental Tectonics Corporation and Subsidiary as of
February 28, 1997 and February 23, 1996, and the related
consolidated statements of operations, changes in stockholders'
equity and cash flows for the years then ended.  These financial
statements are the responsibility of the Company's management. 
Our responsibility is to express an opinion on these 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.

     As discussed in Note 1 to the consolidated financial
statements, the Company has recorded receivables in the amount of
$2.9 million for claims made to or against the United States and
foreign governments for contract costs incurred through
February 28, 1997.  The total net claims amount made and to be
made are approximately $8.6 million based on costs incurred
through February 28, 1997 and are subject to negotiation,
arbitration, and audit by the United States and foreign
governments.

     In our opinion, the consolidated financial statements
referred to above present fairly, in all material respects, the
consolidated financial position of Environmental Tectonics
Corporation and Subsidiary as of February 28, 1997 and
February 23, 1996, and the consolidated results of their
operations and cash flows for the years then ended in conformity
with generally accepted accounting principles.
