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

               On April 1, 1996 and April 19, 1996, the Company completed the
               purchase of certain assets of Ketema, Inc. ("Ketema") and Gettys
               Corporation and Gettys Property Corporation ("Gettys"),
               respectively. These acquisitions were primarily financed through
               a $20,000,000 credit agreement between the Company and Marine
               Midland Bank. Both transactions will be accounted for under the
               purchase method of accounting.

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

REVENUES

Consolidated revenues in the first quarter of 1996 increased 14.2% as compared
with the previous year. Sales within the Heat Transfer segment increased 16.5%
and reflect the strength of the capital goods market evidenced by the 23.0%
increase in orders booked as compared to the prior year. The increase of 19.3%
in sales of the Motion Technologies segment is the result of higher sales of
electromagnetic clutches and brakes to new and existing customers combined with
an increase in market share of products offered by Harowe Servo Controls Inc.
The Electronic Components segment sales decreased 2.0% and is due to a decrease
in the selling price of its axial-leaded products partially offset by increased
volume.

Bookings of customer orders in the first quarter of 1996 were $25,353,000, up
14% over bookings in the same period last year. The Company's consolidated
backlog of firm orders at March 29, 1996 was $33,160,000, up 33% from
$24,909,000 on March 31, 1995.

SELLING AND ADMINISTRATIVE EXPENSES

Selling and administrative expenses, expressed as a percentage of net sales,
declined for the first quarter as compared to the same period in 1995. The
dollar increase is due primarily to increases in sales commissions and
provisions made under the Company's incentive program.

INTEREST AND DEBT EXPENSE

The increase in interest and debt expense is directly related to the industrial
revenue bond financing obtained at the end of 1995 for the construction of the
new Air Technologies facility.

NET EARNINGS

Net earnings increased 34.3% as compared to the prior year primarily due to
increased sales combined with a small decline in costs and expenses as a
percentage of net sales.


                                                                            8

                 2.1      REVOLVING CREDIT.

                          (a)     ADVANCES.  Subject to the terms and
conditions of this Agreement and relying upon the representations and
warranties set forth in this Agreement, the Bank agrees that it will, from time
to time during the period commencing on the date the conditions specified in
Section 3.1 are satisfied through the Business Day preceding the Term Credit

further Advances shall be made on or after the Termination Date, at which time
the Revolving Credit must be paid in full or qualify for, and the Company must
so elect, a conversion to the Term Credit pursuant to Section 2.2 hereof.

                          (b)     METHOD FOR REVOLVING CREDIT ADVANCES.  If and
when the Company wishes the Bank to make an Advance available, the Company
shall notify the Bank not later than 10:00 a.m. (New York time) on the Business
Day on which the Advance is to be funded in the case of a Prime Rate Loan or
Fixed Rate Loan and in the case of a LIBOR Rate Loan not later than two (2)
Business Days prior to the proposed commencement date of a LIBOR Rate Period.
The Company shall specify (i) the aggregate amount of the Advance to be made on
a designated date, which shall be at least $100,000.00 for a Prime Rate Loan or
Fixed Rate Loan and $500,000 for a LIBOR Rate Loan and shall be in whole
multiples of $100,000 for all Loans; (ii) whether the Advance shall be a Prime
Rate Loan, a Fixed Rate Loan or a LIBOR Rate Loan; and (iii) the proposed date
on which the Advance is to be funded, which shall be a Business Day.  As early
as practically possible on the date





                                     - 8 -
<PAGE>   13
on which the Advance is to be made and upon fulfillment of the conditions set
forth in Article III of this Agreement, the Bank will make the proceeds of such
Advance available to the Company.

                          The Bank shall not incur any liability to the Company
in acting upon any notice referred to above or upon any telephonic notice which
the Bank believes in good faith to have been given by a duly authorized officer
or other person authorized to borrow on behalf of the Company or for otherwise
acting in good faith.

                          (c)     THE REVOLVING NOTE.  The Advances made by the
Bank shall be evidenced by a note of the Company to the Bank with blanks
appropriately completed in the form of Exhibit A annexed hereto and made a part
hereof ("Revolving Note").

                          The Revolving Note shall be inscribed by the Bank as
holder of the Note on the schedule on the reverse side thereof or any
continuation thereof ("Schedule") with the date and amount of the outstanding
principal balance of the Advances, the Rate Option applicable to such Advances,
the applicable interest periods, and all payments and prepayments made thereon
and the dates thereof.  Any such inscription shall constitute prima facie
evidence of the accuracy of the information so recorded; provided, however, the
failure of the Bank to make any such inscription shall not affect the Company's
obligations under the Note or this Agreement.

                 2.2      TERM CREDIT CONVERSION.

                          (a)     The Company may, at any time on or before the
Term Credit Conversion Date, deliver a written conversion notice to the Bank
requesting that any amount outstanding under the Revolving Credit be converted
on the Termination Date ("Conversion Notice") to a term loan payable in
forty-seven equal, consecutive, monthly principal installments with one final
installment in an amount equal to the then unpaid principal amount remaining
("Term Credit").  Provided the Company executes and delivers to the Bank a duly
executed Term Note with all blanks appropriately completed, together with an
executed Compliance Certificate from the Company indicating no existing Default
or Event of Default, such request shall be granted by the Bank.

                          (b)     At the time of a conversion pursuant to
Section 2.2 hereof, the Revolving Note shall be replaced by the term note with
blanks appropriately completed in the form of Exhibit B annexed hereto and made
a part hereof ("Term Note").

                 The Term Note shall be inscribed by the Bank as a holder of
the Term Note on the Schedule on the reverse side thereof or any continuation

<PAGE>   14

the Rate Options applicable to such Loans, the applicable interest periods, and
all payments and prepayments made thereon and the dates thereof.  Any such
inscription shall constitute prima facie evidence of the accuracy of the
information so recorded; provided, however, the failure by the Bank to make any
such inscription shall not affect the Company's obligations under the Term Note
or this Agreement.

                 2.3      INTEREST, RATE OPTIONS AND PRICING.  The interest to
be charged on the Revolving Note and the Term Note shall be determined based on
the Rate Options and interest pricing provisions in effect in accordance with
the terms of this Section and Section 2.4 of this Agreement.  The Revolving
Note and the Term Note shall each bear interest on the unpaid principal amounts
from time to time unpaid until maturity (whether by acceleration or otherwise)
at a per annum rate of interest selected by the Company from the Rate Options
set forth below or, in default of a validly selected option, in accordance with
the Prime Rate Option then in effect:

                          (a)     PRIME RATE OPTION.  Unless another Rate
Option is validly selected and in effect pursuant to this Agreement or a
Pricing Event has occurred, the Notes shall bear interest under the Prime Rate
Option at the initial Prime Rate Pricing shown on the Pricing Grid set forth in
Section 2.4 of this Agreement.  If a Pricing Event has occurred and another
Rate Option is not in effect, then the rate of interest applicable to the Notes
shall be the Prime Rate Option as determined based on the Pricing Grid.  The
rate of interest on all Prime Rate Loans shall change simultaneously with each
change in the Prime Rate.

                          (b)     LIBOR RATE OPTION.  Subject to the provisions
of Section 2.1(b) hereof, the Company may elect to have an Advance or Loan made
as a LIBOR Rate Loan for a LIBOR Rate Period provided the amount of such LIBOR
Rate Loan is not less than $500,000 and is in whole multiples of $100,000.  All
LIBOR Rate Loans shall bear interest at the initial LIBOR Rate set forth on the
Pricing Grid until such time as a Pricing Event occurs.

                          (c)     FIXED RATE OPTION.  Subject to the provisions
of Section 2.1(b) hereof, the Company may elect to have an Advance or Loan made
as a Fixed Rate Loan for a Fixed Rate Period provided the amount of such Fixed
Rate Loan is not less than $100,000 and is in whole multiples of $100,000.  All
Fixed Rate Loans shall bear interest at the initial Fixed Rate set forth on the
Pricing Grid until such time as a Pricing Event occurs.

                          (d)     RATE CONVERSIONS AND CONTINUATIONS.  The
Company may elect to convert any portion of (i) a Prime Rate Loan or a Fixed
Rate Loan to a LIBOR Rate Loan, (ii) a LIBOR Rate Loan to either a Fixed Rate
Loan or a Prime Rate Loan, (iii) a Prime





                                     - 10 -
<PAGE>   15
Rate Loan to a Fixed Rate Loan, and (iv) a Fixed Rate Loan to a Prime Rate
Loan, or to continue any LIBOR Rate Loan, Fixed Rate Loan or Prime Rate Loan as
a new loan of the same type, by giving irrevocable notice of such election to
the Bank by 10:00 a.m. (New York time) at least two (2) Business Days prior to
the requested Rate Change Date and, in the case of any LIBOR Rate Loan or Fixed
Rate Loan, such conversion or continuation shall take place on the last day of
the applicable LIBOR Rate Period or Fixed Rate Period, as appropriate, with
respect to the loan being so converted or continued.  Each such request to
convert or continue shall include the Rate Option, the requested Rate Change
Date (which shall be a Business Day), the Rate Option selected, and the amount
to be converted or continued (which shall be in a principal amount of
$500,000.00 or more and in whole multiples of $100,000.00 in the case of
conversion to or continuation as, a LIBOR Rate Loan, and in a principal amount
of $100,000 or more and in whole multiples of $100,000 in the case of a
continuation or conversion as a Prime Rate Loan or Fixed Rate Loan.  If no
Default or Event of Default has occurred and is continuing at such time as
evidenced by the Bank's receipt of a properly completed and executed Compliance
Certificate from the Company, such conversion or continuation shall be made on
the requested Rate Change Date, subject to the foregoing limitations in
connection with the conversion or continuation of LIBOR Rate Loans and Fixed
Rate Loans.

                          The Bank shall not incur any liability to the Company
in acting upon any telephonic notice which the Bank believes to have been given
by a duly authorized officer or other person authorized to and on behalf of the
Company or for otherwise acting in good faith under this Section 2.3(d).

                          (e)     COMPUTATION OF INTEREST.  Interest on the
Notes shall be computed on the basis of a 360-day year for the actual number of
days elapsed, which will result in a higher effective annual rate.  Interest on
the Revolving Credit shall be payable monthly on the first day of each month,
on the Term Credit Conversion Date and the Termination Date.  Interest on the
Term Credit shall be payable quarterly on the first day of each July, October,
January and April hereafter during the term of the Term Credit commencing July

Rate Loans, interest shall also be payable on the last day of each applicable
LIBOR Rate Period, if earlier.

                          (f)     DEFAULT RATE.  After maturity of the Credit,
whether by acceleration or otherwise, Company shall pay interest at a per annum
rate equal to three percent (3%) plus the Prime Rate.  In no event shall the
rate of interest exceed the maximum rate permitted by applicable law.  If
Company pays interest in excess of the amount permitted by applicable law, such
excess





                                     - 11 -

shall be applied in reduction of the principal of Advances made pursuant to
this Agreement.

                          (g)     LATE CHARGE.  Upon failure to make any
payment of interest or principal on the Notes within ten (10) days of the due
date thereof, Company promises to pay, upon demand by the Bank, a late charge
equal to five percent (5%) of the amount of any such overdue amount of
principal or interest.

                          The assessment and/or collection of late charges
shall in no way impair the right of the Bank to pursue any other remedies
hereunder.

interest to be charged for each LIBOR Rate Loan, Fixed Rate Loan or Prime Rate

right to prepay without premium all or any portion of the LIBOR Rate Loans on
the expiration day of the applicable LIBOR Rate Period.  If any LIBOR Rate Loan
is prepaid at any other time, the Company shall, upon not less than ten (10)
days prior written notice, pay to the Bank an amount equal to (i) the interest
which would have otherwise been payable on the amount prepaid during the
remaining term of the LIBOR Rate Period, less (ii) interest on the amount
prepaid for such term computed at an interest rate equal to the
yield-to-maturity which could be obtained on United States Treasury
obligations, purchased in the market at the time of prepayment, having a
remaining term and coupon rate comparable to the remaining term of the LIBOR
Rate Period, and comparable to the applicable interest rate, as determined by
the Bank in good faith, and certified to the Company, such certificate to be
conclusive, absent manifest error.  Any permitted partial prepayment of
principal shall be in the amount of $100,000.00 or a whole multiple thereof,
and in the case of the Term Note shall be applied upon installments of
principal of the Term Note in inverse order of maturity.

                          (c)     FIXED RATE LOANS.  The Company shall have the
right to repay without premium all or a portion of any Fixed Rate Loan only on
the expiration day of the applicable Fixed Rate Period.  If any Fixed Rate Loan
is prepaid at any other time, the Company shall pay to the Bank on demand such
amount or amounts as the Bank determines in good faith is necessary to
compensate it for any loss and expense sustained or incurred by the Bank with
respect to such prepayment.  Any permitted partial repayment of principal shall
be in the amount of $100,000 or a whole multiple thereof, and in the case of
the Term Note shall be applied upon installments of principal of the Term Note
in inverse order of maturity.

                 2.6      USE OF PROCEEDS.  The Company covenants to the Bank

acquire the assets of the Heat Transfer Division of Ketema, Inc. pursuant to
the terms of the Ketema Purchase Agreement.

                          The Company further covenants to the Bank that it
will use the proceeds advanced under this Agreement subsequent to the initial
Advance for general working capital, and to acquire the assets of Gettys

Purchase Agreement.

                 2.7      SPECIAL PROVISIONS GOVERNING LIBOR RATE LOANS -
                          INCREASED COSTS.

                          (a)     In the event that on any LIBOR Interest
Determination Date, the Bank shall have reasonably determined (which
determination shall be final, conclusive and binding) that:

                                  (1)      by reason of conditions in the
London interbank market or of conditions affecting the position of any Bank
in such market occurring after the date hereof, adequate fair means do not exist
for establishing LIBOR, or

                                  (2)      by reason of (i) any applicable law
or governmental rule, regulation, guideline or order (or any written
interpretation thereof and including any new law or governmental rule,
regulation, guideline or order but excluding any of the foregoing relating to
taxes referred to in Section 2.9 of this Agreement) or (ii) other circumstances
affecting the Bank or the London interbank market or the position of the Bank in
such market (such as, but not limited to, official reserve requirements), the
LIBOR Rate does not represent the effective pricing to the Bank for U.S. dollar
deposits of comparable amounts for the relevant period due to such increased
costs then, the Bank shall give a notice by telephone, confirmed in writing, to
the Company of such determination.

                          (b)     Thereafter, the Company shall pay to the Bank
upon written request therefor, such additional amounts as the Bank in its sole
discretion, shall reasonably determine to be required to compensate the Bank
for such increased costs.  A certificate as to such additional amounts
submitted to the Company by the Bank shall, absent manifest error, be final,
conclusive and binding upon all parties hereto.

                          (c)     In lieu of paying such additional amounts as
required by this Section, the Company may exercise the following options:

                                  (1)      If such determination relates only
to a conversion to a LIBOR Rate Loan then being requested by the Company
pursuant to the terms hereof, the Company may, on such





                                     - 14 -
<PAGE>   19
LIBOR Interest Determination Date by giving notice by telephone to the Bank,
withdraw such request.


                                  (2)      The Company may, by giving notice by
telephone to the Bank, require the Bank to convert the LIBOR Rate Loan then
being requested to a Prime Rate Loan or Fixed Rate Loan, or to convert its
outstanding LIBOR Rate Loan that is so affected into a Prime Rate Loan or Fixed
Rate Loan at the end of the then current LIBOR Rate Period.

                 2.8      REQUIRED TERMINATION AND REPAYMENT OF LIBOR RATE
                          LOANS.

                          (a)     In the event the Bank shall have reasonably
determined, at any time (which determination shall be final, conclusive and
binding but shall be made only after consultation with the Company and the
Bank), that the making or continuation of any or all of LIBOR Rate Loans by the
Bank:

                                  (1)      has become unlawful by compliance by
                          such Bank in good faith with any applicable law,
                          governmental rule, regulation, guideline or order, or

                                  (2)      would cause the Bank severe hardship
                          as a result of a contingency occurring after the date
                          of this Agreement which materially and adversely
                          affects the London interbank market (such as, but not
                          limited to disruptions resulting from political or
                          economic events);

                          then, and in either such event, the Bank shall on
such date (and in any event as soon as possible after making such
determination) give telephonic notice to the Company, confirmed in writing, of
such determination, identifying which of the LIBOR Rate Loans are so affected.

                          (b)     The Company shall, upon the termination of
the then current LIBOR Rate Period applicable to each LIBOR Rate Loan so
affected or, if earlier, when required by law, repay each such affected LIBOR
Rate Loan, together with all interest accrued thereon.

                          (c)     In lieu of the repayment required by Section
2.8(b), the Company may exercise the following options:

                                  (1)      If the determination by the Bank
relates only to a LIBOR Rate Loan then being converted by the Company pursuant
to the terms hereof, the Company may, on such date by giving notice by
telephone to the Bank, withdraw such request for conversion.





                                     - 15 -
<PAGE>   20
                                  (2)      The Company may, by giving notice in
writing or by telephone to the Bank, require the Bank to convert the LIBOR Rate
Loan then being converted to a Prime Rate Loan or Fixed Rate Loan or to convert
any outstanding LIBOR Rate Loan or LIBOR Rate Loans that are so affected into a
Prime Rate Loan or Fixed Rate Loan at the end of the then current LIBOR Rate
Period (or at such earlier time as repayment is otherwise required to be made
pursuant to Section 2.8(b)).  Such notice shall pertain only to the LIBOR Rate
Loan or LIBOR Rate Loans outstanding or to be outstanding during each such
affected LIBOR Rate Period.

                 2.9      TAXES.  If any taxes (other than taxes with respect
to the income of the Bank), or duties of any kind shall be payable, or ruled to
be payable, by or to any taxing authority of or in the United States, or any
foreign country, or any political subdivision of any thereof, in respect of any
of the transactions contemplated by this Agreement (including, but not limited
to, execution, delivery performance, enforcement, or payment of principal or
interest of or under the Note or this Agreement, or the making of a LIBOR Rate
Loan), by reason of any now existing or hereafter enacted statute, rule,
regulation or other determination (excluding any taxes imposed on or measured
by the net income of the Bank), the Company will:

                          (a)     pay on written request therefor all such
taxes or duties, including interest and penalty, if any,

                          (b)     promptly furnish the Bank with evidence of
any such payment, and

                          (c)     indemnify and hold the Bank and any holder or
holders of the Note harmless and indemnified against any liability or
liabilities with respect to or in connection with any such taxes or the payment
thereof or resulting from any delay or omission to pay such taxes; provided,
however, the Company shall not be responsible for any such liability arising
from the late payment of such taxes if such late payment was caused by the
Bank's failure to notify the Company of the Company's obligation to pay such
taxes prior to the due date therefor.

                 2.10     FACILITY FEE.  The Company shall pay to the Bank on
the date hereof as consideration for its execution of this Agreement, a
facility fee of $25,000.

                 2.11     UNUSED LINE FEE.  The Company agrees to pay to the
Bank a fee computed at the rate of 1/8% per annum based on a 360-day year on
the average daily unused amount of the total Commitment made available
hereunder, which fee shall be payable monthly on the first day of each month
after the date hereof until the Revolving Credit is finally and irrevocably
paid in full or converted to the Term Credit.

by written notice to the Bank state its desire to reduce the Commitment of the
Bank to any amount which is not less than the aggregate then outstanding
principal amount of Advances.  Any reductions of the Commitment shall not be
reinstated at any future date and any partial reduction shall be in the amount
of $1,000,000.00 or a whole multiple thereof.  Two Business Days after receipt
of such reduction notice, the obligation of the Bank to make Advances hereunder
shall be limited to its Commitment as reduced pursuant to such notice.

                 2.13     PAYMENTS.  All payments of interest, principal, fees
and other expenses by the Company under this Agreement shall be made in
immediately available funds not later than 12:00 p.m. on the due date at the
Bank's office, unless such amount is paid by the Bank's debiting a deposit
account of the Company.

                 2.14     CHARGE TO ACCOUNT.  On the date that any principal of
or interest on the Notes, or any fees or charges payable under this Agreement,
are due, the Company authorizes the Bank to debit the deposit account of the
Company maintained with the Bank, Account No. 750-00509-2, on such due date in
