                                     PART I

Item 1. Business.

     (a) General Development of Business.

     The Registrant, a Delaware corporation, was incorporated in 1942. The
primary businesses of the Registrant are:

        (i) The development, manufacture, and sale of PEM(R) self-clinching and
broaching fasteners, inserts for plastic, and automatic insertion equipment for
such fasteners sold under the name PEMSERTER(R); and

        (ii) The development, manufacture, and sale through the Registrant's
Pittman division of permanent magnet field, brush-commutated dc electric motors
under the Pittman(R) and Pitmo(R) trademarks, and electronically commutated
brushless dc servomotors under the Elcom(R) trademark.

     (b) Financial Information About Industry Segments.

     The answer to this Item is incorporated by reference to Note 13 of the
Notes to Consolidated Financial Statements "Financial Reporting for Segments of
the Registrant" on pages 22 and 23 of the Registrant's 1998 Annual Report to
Stockholders which is included as Exhibit (13) to this Form 10-K Report.

     (c) Narrative Description of Business.

     The Registrant is the world's leading manufacturer of self-clinching
fasteners used by the computer, data communications, telecommunications, general
electronics, automotive, and avionics industries. PEM self-clinching fasteners,
which accounted for approximately 82% of the Registrant's sales in 1998, were
first developed by the Registrant's founder in 1942. Self-clinching fasteners
become an integral part of the material in which they are installed and provide
a reliable means of attaching components to sheet metal or plastic. Typical
applications for the Registrant's fastener products include personal computers,
computer cabinetry, power supplies, instrumentation, telecommunications
equipment, and certain automobile parts, such as air bags and windshield wipers.
The Registrant's Pittman division manufacturers high performance permanent
magnet dc motors used in electronics, medical, and manufacturing applications.

     The Registrant's fasteners are primarily used by sheet metal fabricators
which utilize the Registrant's fasteners to produce sub-assemblies for original
equipment manufacturers ("OEMs"). Both OEMs and their subcontractors seek
fastening solutions which provide lower total installed cost and are highly
reliable, thereby lowering production and service costs. The Registrant's
application engineers and independent distributors continually work in close
collaboration with OEMs and their subcontractors to determine appropriate
fastener applications, which often results in OEMs specifying the Registrant's
fasteners. Self-cinching fasteners generally


                                      -1-
<PAGE>

compete against loose hardware, such as nuts and bolts. The Registrant's
fasteners typically sell at a premium to loose hardware. However, the
Registrant's fasteners generally result in lower overall manufacturing costs for
the end user.

     The Company also manufactures and sells manual and automated
presses for fastener installation under the PEMSERTER trademark. The rapid and
accurate installation provided by PEMSERTER presses, together with the Company's
broad range of fastener products, provides the Company's customers with a
complete fastening system.

     The Registrant's Pittman division produces high-quality, high-performance,
permanent magnet dc motors used in light-weight precision applications such as
archival storage, printing, copying, robotics, and medical diagnostic equipment
and centrifuges. Pittman's broad range of products are typically adapted to the
specific requirements of individual customers.

     The manufacture and sale of (i) self-clinching and broaching fasteners and
inserts for plastic and (ii) dc motors are the Registrant's only lines of
business. The following table sets forth information with respect to the
percentage of total sales attributable to each of the Registrant's principal
products which accounted for 10% or more of consolidated revenues in each of the
fiscal years ended December 31, 1996, 1997 and 1998:

                                    Percentage of Total Sales   
                                    -------------------------

           December 31,             Fasteners           Motors 
           ------------             ---------           ------ 
               1996                   82%                 18%
               1997                   81%                 19%
               1998                   82%                 18%

     The Company's fastener products are sold through a worldwide network of
approximately 40 authorized distributors located in 34 countries and the
Company's own subsidiaries in Singapore and England. Many of the independent
distributors and engineering representative organizations have been affiliated
with the Company for more than 20 years. The Company's independent distributors,
which maintain their own inventories of the Company's products, typically sell
other complimentary industrial components. The Company's return allowances,
which are made through the exchange of inventory, have generally averaged less
than 1% of sales. The Company's engineers work in collaboration with individual
manufacturers early in the design process to engineer fastening solutions that
often result in the specification of PEM fasteners in new products. The Company
supplies its customers and distributors through warehouses in Doncaster, England
and Singapore, in addition to maintaining an inventory at its Danboro,
Pennsylvania facility.

     Domestic and European sales of Pittman motors are handled by independent
sales representatives.



                                      -2-
<PAGE>

     During the year ended December 31, 1998, conditions in the domestic market
for fasteners continued to be highly competitive. It is not possible to
determine with accuracy the relative competitive position of the Registrant in
the market for self-clinching, broaching, and insert fasteners. The Registrant
believes that it has maintained its market share during 1998. Approximately ten
other companies are known to be competing with the Registrant in the manufacture
and sale of such fasteners, some of which also manufacture products other than
self-clinching, broaching, and insert fasteners.

     The Registrant also believes its Pittman division maintained its
competitive position in the dc motor market in 1998.

     Among the Registrant's principal customers for fasteners and PEMSERTERS(R)
are manufacturers of business machines, personal computers and computer
peripherals, electronic and communications equipment, electrical equipment,
industrial controls instrumentation, vending machines, automotive
subcontractors, and other fabricated metal products. The principal customers for
the dc motors and servomotors are manufacturers of automated production
equipment, instruments, computer peripherals, business machines, and medical
equipment. In the opinion of the Registrant, no material part of its business is
dependent upon a single customer or a few customers, the loss of any one or more
of which would have a material adverse effect on the business of the Registrant.
However, sales of fasteners to one of the Registrant's authorized distributors
totaled approximately $21,830,000 for the year ended December 31, 1996,
$20,687,000 for the year ended December 31, 1997, and $21,060,000 for the year
ended December 31, 1998, or approximately 13.6%, 12.3%, and 11.7%, respectively,
of the Registrant's consolidated net sales in such years. Sales of fasteners to
another of the Registrant's authorized distributors totaled approximately
$19,827,000 for the year ended December 31, 1997 and $22,885,000 for the year
ended December 31, 1998, or approximately 11.8% and 12.7%, respectively, of the
Registrant's consolidated net sales during such years.

     As of December 31, 1998, the Registrant had an order backlog of $45,105,000
compared with $57,249,000 as of December 31, 1997. The Registrant estimates that
substantially all of its backlog as of December 31, 1998 will be shipped during
its fiscal year ending December 31, 1999.

     The raw materials used by the Registrant are generally available in
adequate supply.

     The Registrant holds a number of patents and trademarks, and has patent
applications pending, in the United States and various foreign countries.
Management believes, however, that the Registrant's business is not materially
dependent on any patent or group of patents. The principal trademarks of the
Registrant are registered in the United States and various foreign countries.

     Research and development is carried on by the operating personnel of the
Registrant on a continuing basis. The amounts expended for research and
development for the fiscal years ended December 31, 1996, 1997, and 1998 were
approximately $1,520,000, $2,944,000, and $3,410,0000, respectively.



                                      -3-
<PAGE>

     The Registrant believes that compliance with federal, state, and local laws
and regulations that have been enacted or adopted regulating the discharge of
materials into the environment, or otherwise relating to the protection of the
environment, will not have a material adverse effect upon the earnings or
competitive position of the Registrant.

     As of December 31, 1998, 1,423 persons were employed by the Registrant, 55
more than were employed as of December 31, 1997. None of the Company's personnel
are governed by collective bargaining agreements. The Company believes that its
labor rates are comparable to those of its competitors and that the Company's
relations with its employees are good. The Registrant does not consider its
business to be seasonal in any material respect, nor is any material portion of
the Registrant's business subject to the renegotiation of profits or termination
of contracts at the election of the Government.

     (d)  Financial Information About Foreign and Domestic
          Operations and Export Sales.

     The answer to this Item is incorporated by reference to Note 13 "Financial
Reporting for Segments of the Company" on pages 22 and 23 of the Registrant's
1998 Annual Report to Stockholders, which is included as Exhibit (13) to this
Form 10-K. Also, all foreign sales except for those of PEM International, Ltd.
and PEM International (Singapore) Pte Ltd. are sold F.O.B., the Registrant's
factory, payable in U.S. dollars. Sales in the United Kingdom and Western Europe
are made through the Registrant's wholly owned subsidiary, PEM International,
Ltd., and are denominated in pounds sterling. Sales in the Pacific Rim are made
through the Registrant's wholly owned subsidiary, PEM International (Singapore)
Pte Ltd., and are denominated in Singapore dollars. All foreign sales are
subject to special risks of exchange controls and restrictions on the
repatriation of funds and also may be affected by the imposition or increase of
taxes and/or tariffs and international instability.

Item 5. Market for Registrant's Common Equity and Related
        Stockholder Matters.

     The Registrant's Common Stock (non-voting), par value $0.01, is traded on
the New York Stock Exchange under the symbol "PNN." The Registrant's Class A
Common Stock (voting), par value $0.01, is traded on the New York Stock Exchange
under the symbol "PNNA." As of March 25, 1999, there were 571 holders of record
of the Registrant's Common Stock and 441 holders of record of the Registrant's
Class A Common Stock. Additional information with respect to this Item 5 is
incorporated by reference to page 14 of the Registrant's 1998 Annual Report to
Stockholders, which is included as Exhibit (13) to this Form 10-K Report.

Item 6. Selected Financial Data.

     The Five-Year Financial Data and other financial information for the
Registrant is incorporated by reference to page 9 of the Registrant's 1998
Annual Report to Stockholders, which is included as Exhibit (13) to this Form
10-K Report.

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

     The answer to this Item is incorporated by reference to pages 10 through 14
of the Registrant's 1998 Annual Report to Stockholders, which is included as
Exhibit (13) to this Form 10-K Report.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk.

     The Registrant=s earnings and cash flow are subject to fluctuations due to
changes in foreign currency exchange rates. The Registrant manages its exposures
to changes in foreign currency exchange rates on certain firm sales commitments
and anticipated, but not yet committed sales, by entering into foreign currency
forward contracts and foreign currency option contracts, respectively. The
Registrant=s risk management objective is to reduce its exposure to the effect
of changes in exchange rates on sales revenue over quarterly time horizons. To a
certain extent, foreign currency rate movements also affect the Registrant=s
competitive position, as exchange rate changes may affect business practices
and/or pricing strategies of non-U.S. based competitors. The Registrant=s
foreign currency risk policies entail entering into foreign currency derivative
instruments only to manage risk, not for speculative investments.

     Annually, financial officers approve the Registrant=s outlook for expected
currency exchange rate movements, as well as the policy on desired future
foreign currency cash flow positions (long, short, balanced) for those
currencies where there is significant activity. Financial officers receive a
daily report on open foreign currency hedges. Expected future cash flow
positions and strategies are continuously monitored. Foreign exchange management
practices,

including the use of derivative financial instruments, are presented to the
Audit Committee of the Registrant=s Board of Directors at least annually.

     Considering both the anticipated cash flows from firm sales commitments
plus anticipated sales for the next quarter and the foreign currency derivative
instruments in place at year end, a hypothetical 10% weakening of the U.S.
dollar relative to all other currencies would not materially adversely affect
expected 1999 earnings or cash flows. This analysis is dependent on actual
export sales during the next quarter occurring within 90% of the budgeted
forecasts. The effect of the hypothetical change in exchange rates ignores the
effect that this movement may have on other variables including competitive
risk. If it were possible to quantify this competitive impact, the results could
well be different than the sensitivity effect shown above. In addition, it is
unlikely that all currencies would uniformly strengthen or weaken relative to
the U.S. Dollar. In reality, some currencies may weaken while others strengthen.
