              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2001

NOTE 1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
---------------------------------------------------------------

     The accompanying interim financial statements should be read in conjunction
with the annual financial statements and notes thereto included in the Company's
Annual Report for the year ended December 31, 2000. The information contained in
this report is unaudited and subject to year-end audit and adjustment. In the
opinion of management, all adjustments (which include only normal recurring
adjustments) have been made which are necessary for a fair presentation of the
Company's consolidated financial position at September 30, 2001 and 2000 and the
consolidated statements of income and cash flows for the nine-month periods then
ended. The results of operations for the three and nine months ended September
30, 2001 are not necessarily indicative of the results of operations to be
expected for the year ending December 31, 2001.

NOTE 2. INVENTORIES
-------------------

     Substantially all of the Company's domestic fastener inventories are priced
on the lower of last-in, first-out (LIFO) cost or market method. The remainder
of the inventories are priced on the first-in, first-out (FIFO) method, at the
lower of cost or market.

     Inventories are as follows: (dollars in thousands)

                                          (UNAUDITED)

                                       ------------------      -----------------

Raw material                                $ 6,241                 $ 6,157
Tooling                                       4,250                   4,145
Work-in-process                              10,921                  12,828

TOTAL                                       $59,992                 $46,847
                                            =======                 =======

     If the FIFO method of inventory valuation had been used by the Company for
all inventories, inventories would have been $11,147,000 and $10,322,000 higher
than reported at September 30, 2001 and December 31, 2000, respectively, and net
income would have been $576,000 and $635,000 higher than reported for the nine
months ended September 30, 2001 and 2000, respectively. Other assets consist of
long-term tooling inventory totaling $3,000,000 and $3,500,000 at September 30,
2001 and December 31, 2000, respectively.

NOTE 3. BANK DEBT
-----------------

     As of September 30, 2001, the Company has three unsecured line-of-credit
facilities available. All lines-of-credit bear interest at interest rate options
provided in the facilities. The first line-of-credit facility permits maximum
borrowings of $15,000,000, due on demand. At September 30, 2001, $8,580,000,
bearing interest at 3.13%, was outstanding on this facility. The availability of
funds under this facility is periodically reviewed by the bank. The second
line-of-credit facility permits borrowings of up to $10,000,000 and expires on
November 30, 2001 unless extended by the bank. At September 30, 2001,
$1,508,000, bearing interest at 3.13%, was outstanding on this facility. In
addition to the above short-term lines of credit, the Company has an unsecured
line of credit with a bank that permits borrowings of up to $30,000,000 to
finance acquisitions. At September 30, 2001, $721,000, bearing interest at
5.3295%, was outstanding on this facility and has been classified as short-term
debt. The acquisition line of credit requires the Company to comply with certain
financial covenants. At September 30, 2001 the Company was in compliance with
all financial covenants. The Company also has two commercial loans outstanding
as of September 30, 2001 for a total amount of $7,350,000. As of September 30,
2001, the loans are classified as short-term debt since it is the Company's
intention to liquidate this debt within one year. The interest rate on both
loans is 5.45%.

NOTE 4. COMPREHENSIVE INCOME
----------------------------

     Total comprehensive income amounted to $2,623,000 and $7,429,000 for the
three months ended September 30, 2001 and 2000, respectively and $11,619,000 and
$19,049,000 for the nine months ended September 30, 2001 and 2000, respectively.

NOTE 5. USE OF ESTIMATES
------------------------

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

NOTE 6. SEGMENT INFORMATION
---------------------------

     Effective January 1, 2001, the Company reorganized its operations and
implemented a new internal reporting system. As a result of this reorganization,
the Company has subdivided what was previously called the fasteners segment into
two reportable segments - fasteners (which includes the results of PEM Fastening
Systems and Atlas Engineering) and distribution (which includes the results of
the Arconix Group). There is no change in the motor segment (which includes the
results of Pittman). Due to the nature of this change, it is impracticable to
restate prior years segment data in a manner consistent with current year data.
Segment data reported in a manner consistent with prior years is as follows:

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2001

NOTE 9. RECENT ACCOUNTING DEVELOPMENTS
--------------------------------------

     In June 2001, the Financial Accounting Standards Board issued Statements of
Financial Accounting Standards No, 141, "Business Combinations", and No. 142,
"Goodwill and other Intangible Assets", effective for fiscal years beginning
after December 15, 2001. Under the new rules, goodwill and intangible assets
deemed to have indefinite lives will no longer be amortized but will be subject
to annual impairment tests in accordance with the Statements. Other intangible
assets will continue to be amortized over their useful lives.

     The Company will apply the new rules on accounting for goodwill and other
intangible assets beginning in the first quarter of 2002. Application of the
nonamortization provisions of the Statement is expected to result in an increase
in net income of $960,000 ($0.05 per share) per year. The Company will perform
the first of the required impairment tests of goodwill as of January 1, 2002 and
has not yet determined what the effect of these tests will be on the earnings
and financial position of the Company.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
-------------------------------------------------------------------------------

                     PENN ENGINEERING & MANUFACTURING CORP.
                               SEPTEMBER 30, 2001

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

QUARTER ENDED SEPTEMBER 30, 2001 VS. QUARTER ENDED SEPTEMBER 30, 2000
---------------------------------------------------------------------

     Consolidated net sales for the quarter ended September 30, 2001 were $36.6
million, versus $66.6 million for the quarter ended September 30, 2000, a 45.0%
decrease. Net sales to customers outside the United States for the quarter ended
September 30, 2001 were $11.1 million, versus $16.5 million for the quarter
ended September 30, 2000, a 32.7% decrease. Net sales for the fastener and
distribution operations for the quarter ended September 30, 2001 were $28.6
million, versus $55.8 million for the quarter ended September 30, 2000, a 48.7%
decrease. Motor net sales were $8.0 million for the quarter ended September 30,
2001, versus $10.8 million recorded for the quarter ended September 30, 2000, a
25.9% decrease.

     Within the fastener and distribution operations, sales volume decreased
approximately 50.0% in the third quarter of 2001 compared to the third quarter
of 2000. The number of fastener units sold within North America decreased
approximately 58.5% in the third quarter of 2001 compared to the third quarter
of 2000. The number of fastener units sold into Europe decreased approximately
26.0% in the third quarter of 2001 compared to the third quarter of 2000, while
the number of fastener units sold into the Asia-Pacific region decreased
approximately 33.1% during the same period. The Company continues to be impacted
by the effect of the economic downturn that began early in the year in the PC,
telecommunications, server, and electronics markets, which together constitute
approximately 77% of the Company's sales volume. The downturn appears to be
spreading to our foreign markets as well as our domestic markets. Within the
motor division the number of motors sold decreased 17.4% in the third quarter of
2001 compared to the third quarter of 2000 while the average selling price also
decreased 9.7%. Downturns in the semiconductor and the data storage industries
accounted for a majority of this decrease.

     Consolidated gross profit for the third quarter of 2001 was $11.1 million,
versus $24.1 million for the third quarter of 2000, a decrease of 53.9%.
Fastener and distribution gross profit decreased 56.8% in the third quarter of
2001 compared to the third quarter of 2000 while motor gross profit decreased
37.5%. Both segments were affected by lower sales volume and decreased capacity
utilization. The Company has begun to implement cost saving measures - the
Fastening division will close its Suffolk, Virginia manufacturing facility
effective December 9, 2001 while its Willimantic, Connecticut facility was
closed and disposed of in July 2001. Employee reductions in both the fastener
and motor divisions have also been made to balance Company resources with
current economic conditions and future business requirements. These actions are
expected to result in one-time costs of approximately $1.0 million in the fourth
quarter of 2001.

     Consolidated selling, general, and administrative expenses ("SG&A") for the
third quarter of 2001 were $10.0 million, versus $13.4 million for the third
quarter of 2000. Commission expense decreased 48.7% from the third quarter of
2000 to the third quarter of 2001 due to the reduced sales volume.

     Consolidated net income for the third quarter of 2001 was $0.8 million,
versus $7.5 million for the third quarter of 2000. The Company benefited from
tax refunds due to foreign tax credits from prior years as well as a reduced
effective tax rate from foreign sales tax planning.

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

NINE MONTHS ENDED SEPTEMBER 30, 2001 VS. NINE MONTHS ENDED SEPTEMBER 30, 2000
-----------------------------------------------------------------------------

     Consolidated net sales for the nine months ended September 30, 2001 were
$156.8 million, versus $196.3 million for the nine months ended September 30,
2000, a 20.1% decrease. Net sales to customers outside the United States for the
nine months ended September 30, 2001 were $44.1 million, versus $49.4 million
for the nine months ended September 30, 2000, a 10.7% decrease. Net sales for
the fastener and distribution operations for the nine months ended September 30,
2001 were $129.8 million, versus $164.5 million for the nine months ended
September 30, 2000, a 21.1% decrease. Motor sales were $27.0 million for the
nine months ended September 30, 2001, versus $31.8 million for the nine months
ended September 30, 2000, a 15.1% decrease.

     Within the fastener and distribution operations, sales volume decreased
21.8% from the first nine months of 2000 to the first nine months of 2001. Price
increases averaging 3.2% were put into effect in the fourth quarter of 2000;
however, the full effect of these increases was mitigated by currency
fluctuations in Europe. The number of fastener units sold within North America
decreased approximately 28.0% in the first nine months of 2001 compared to the
first nine months of 2000 due to the economic slowdown in the PC,
telecommunications, server, and electronics markets which began early in the
year. The number of fastener units sold into Europe increased less than 1% in
the first nine months of 2001 compared to the first nine months of 2000 as the
European economy remained steady through the first half of 2001. The number of
fastener units sold into the Asia-Pacific region decreased approximately 26.3%
in the first nine months of 2001 compared to the first nine months of 2000 as
electronics production has fallen off sharply in that region as a result of the
slowdown in the computer market. The number of motors sold decreased 12.0% in
the first nine months of 2001 compared to the first nine months of 2000 and the
average selling price decreased 3.5% during the same period.

     Consolidated gross profit for the first nine months of 2001 was $51.5
million, versus $67.7 million for the first nine months of 2000, a 23.9%
decrease. Fastener and distribution gross profit decreased 23.3% in the first
nine months of 2001 compared to the first nine months of 2000 while motor gross
profit decreased 27.3% during the same period. Both segments continue to be
affected by decreasing volume requirements while much of the Company's cost
savings measures will not be fully realized until the first quarter of 2002.

     Consolidated SG&A expenses for the first nine months of 2001 were $34.1
million (21.7% of net sales), versus $38.8 million (19.8% of net sales) for the
first nine months of 2000. The Company is attempting to adjust its SG&A spending
level to the reduced sales demands through staff reductions and tighter control
over spending.

     Consolidated net income for the first nine months of 2001 was $12.1
million, versus $19.4 million for the first nine months of 2000. The Company
incurred $790,000 of interest expense in the first nine months of 2001 related
to loans outstanding to finance acquisitions and benefited from a lower
effective tax rate in 2001 due to foreign tax credits from prior years.

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

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

     Net cash provided by operations totaled $16.1 million for the nine months
ended September 30, 2001 as compared to $28.3 million in the comparable period
of 2000. The Company's accounts receivable balance decreased $11.2 million from
December 31, 2000 to September 30, 2001 as a result of increased collection
efforts and reduced sales volume. Funds from operations were sufficient to pay
normal dividends and capital expenditures. The Company anticipates that its
existing capital resources and cash flow generated from future operations as
well as existing short-term lines of credit will enable it to maintain its
current level of operations and its planned growth for the foreseeable future.

FORWARD-LOOKING STATEMENTS
--------------------------

     Forward-looking statements, within the meaning of Section 27A of the
Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934
under the Private Securities Litigation Reform Act of 1995, are made throughout
this Management's Discussion and Analysis. The Company's results may differ
materially from those in the forward-looking statements. Forward-looking
statements are based on management's current views and assumptions, and involve
risks and uncertainties that significantly affect expected results. For example,
operating results may be affected by external factors such as: changes in laws
and regulations, changes in accounting standards, fluctuations in demand in
markets served by the Company, particularly the computer and telecommunications
markets, fluctuations in the cost and availability of the supply chain
resources, and foreign economic conditions, including currency rate
fluctuations.
