ITEM 1    BUSINESS

GENERAL

Bowmar Instrument Corporation ("Bowmar") was incorporated in the State of
Indiana in 1951. Bowmar and its subsidiaries (hereinafter sometimes referred to
collectively as the "Company") manufacture and sell microelectronic and
electromechanical products. These products fall into two industry segments -
microelectronic circuits and components ("microelectronic") and
electromechanical and mechanical equipment and components ("electromechanical").

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The sales and operating results of each industry segment and the identifiable
assets attributable to each industry segment for fiscal years 1995, 1994 and
1993 are set forth in Note 13 to the Consolidated Financial Statements.

NARRATIVE DESCRIPTION OF BUSINESS

                            MICROELECTRONIC CIRCUITS

The products designed, manufactured and sold by the Company in its
microelectronic segment include high density, solid state memory modules and
multichip modules for use in both commercial and military applications.

                    HIGH DENSITY, SOLID STATE MEMORY MODULES

The Company designs and manufactures high density memory microcircuits. These
memory modules are designed specifically for use in adverse environmental
conditions. In addition, these solid state memory modules are designed to
provide larger amounts of mass memory, space reduction and faster data
processing speeds. These products are used in both military and commercial
applications and include static RAM modules (SRAM), electronically erasable PROM
modules (EEPROM), and Flash PROM modules.

                                MULTICHIP MODULES

The Company designs and manufactures highly reliable, compact multichip modules
(MCM's). Multichip modules are used as components in a broad spectrum of
electronic devices where circuit reliability and size reduction is important. A
multichip module is a packaging technique that places several semiconductor
chips, interconnected with a high density substrate, into a compact package.
Multichip modules can be designed to perform a wide variety of electronic
functions, such as amplifiers, regulators, switches, data converters,
oscillators and decoders. These products are sold to original equipment
manufacturers serving principally the military market, as well as the aerospace,
medical and high temperature markets.

                         MICROELECTRONIC SEGMENT REVIEW

The products designed, manufactured, and sold by the Company in its
microelectronic segment are sold to private industry and to the United States
and foreign governments both through Company sales personnel and independent
sales representatives and distributors. The materials, products and services
used by the Company to manufacture products in its microelectronic segment are
readily available from a variety of sources. None of the business of the
microelectronic segment is seasonal.

Neither the needs of the Company for a continuing allotment of goods from its
suppliers, nor the requirements of its customers for the products of this
segment require the carrying of significant finished goods inventory.

                                        1
<PAGE>   4
Although the Company purchases components from other manufacturers, some of
which must be ordered several months in advance, it has not encountered, and
does not anticipate encountering, any significant difficulty in obtaining the
components required in its manufacturing operations. The Company does not
provide extended payment terms to its customers. Products in the microelectronic
segment are sold under a standard one year warranty and may be returned for
repair or replacement during the warranty period.

The backlog for products of the microelectronic segment was approximately
$8,249,000 and $11,341,000, at the end of fiscal years 1995 and 1994,
respectively. Approximately 100% percent of this segment's fiscal 1994 backlog
was shipped during fiscal 1995. Approximately 98% percent of the fiscal 1995
year-end backlog is expected to be shipped during fiscal 1996 and the remainder
in fiscal 1997.

Management believes that the key competitive factors affecting its
microelectronic segment are product reliability, the ability to meet delivery
schedules and price. In marketing the products of this segment, the Company
competes with many other companies, many of which have greater financial
strength and technical and marketing resources than does the Company.
Consequently, it is the Company's objective to concentrate its activities in
markets where its resources do not place it at a competitive disadvantage and
where the Company's engineering capabilities and the reliability of its products
are recognized.

            ELECTROMECHANICAL AND MECHANICAL EQUIPMENT AND COMPONENTS

The products designed, manufactured and sold by the Company in its
electromechanical segment include electromechanical components and packages,
electromechanical display devices, electronic display devices, keyboards and
related sub-systems, medical and dental equipment and ordnance products.

                    ELECTROMECHANICAL COMPONENTS AND PACKAGES

The Company's electromechanical components and instrument packages consist of
rotating devices, including gearheads, mechanical counters, dial drives,
mechanical packages and related devices. Specific applications for these
products include controls for automatically tuning airborne radio transmitters
and receivers, controls for fuel flow in jet engines and selected automatic
flight control servomechanisms. These products are sold principally to aircraft
instrument manufacturers as information displays in aerospace and ground
equipment.

                        ELECTROMECHANICAL DISPLAY DEVICES

The Company also produces digital displays which permit a more accurate readout
of information than is feasible with analog meters. These products include
display devices which respond electromagnetically to electronic input signals,
thus eliminating mechanical transmission delays. These products are sold
primarily to aircraft instrument manufacturers.

                               INTERFACE PRODUCTS

The Company designs and manufactures, to customer specification, a variety of
keyboard assemblies for military and commercial aerospace applications. The
Company has the capability of meeting demanding requirements such as
backlighting to meet night vision goggle (NVG) compatibility, adverse
environments, and the integration of displays, including LCD's, and
microprocessor technology.

                           MEDICAL AND DENTAL PRODUCTS

The Company produces and markets a dental/medical equipment sterilizer (Cox
Rapid Heat Sterilizer) which is primarily sold in the dental equipment market.
Other product activities involve the joint development of a new type of dental
x-ray device with Panoramic Corporation. The x-ray system is a real time
intra-oral imaging device which, due to its low patient radiation exposure,
permits the operator to view live x-ray images.

<PAGE>   5
                                    ORDNANCE

The Company produces mechanical and electromechanical fuzing and safing and
arming devices. Fuzes and safing and arming devices are manufactured for use in
various rocket and missile applications, and are sold directly to the U.S.
Government or to U.S. Government military prime contractors.

                     ELECTROMECHANICAL PACKAGES AND SYSTEMS

The Company designs and manufacturers complex specialized systems used in
interface control of cable handling systems aboard submarines and antenna
control systems in satellite communications systems. These products are sold
directly to the U.S. Government or to U.S. Government prime contractors.

                        ELECTROMECHANICAL SEGMENT REVIEW

The customers for the products of the electromechanical segment include original
equipment manufacturers in the aerospace industry and agencies of the United
States Government. The materials, products and services used by the Company to
manufacture its products in the electromechanical segment are readily available
from a variety of sources. None of the business of the electromechanical segment
is seasonal.

Neither the needs of the Company for a continuing allotment of goods from its
suppliers nor the requirements of its customers for the products of the
electromechanical segment require the carrying of finished goods inventory.
While the Company purchases components from other manufacturers, some of which
must be ordered several months in advance, it has not encountered, and does not
anticipate encountering, any significant difficulty in obtaining the components
required in its manufacturing operations. The Company does not provide extended
payment terms to its customers. Products in the electromechanical segment are
sold under a standard one year warranty and may be returned for repair or
replacement during the warranty period.

The backlog for products of the electromechanical segment was approximately
$2,834,000 and $6,887,000, at the end of fiscal years 1995 and 1994,
respectively. Approximately 63% percent of this segment's 1994 backlog was
shipped during fiscal 1995. Approximately 97% percent of the fiscal 1995
year-end backlog is expected to be shipped during fiscal 1996 and the remainder
in fiscal 1997 and 1998.

Management believes that price, product reliability and the ability to meet
delivery schedules are the key competitive factors relating to the Company's
products. Since many of the Company's competitors have greater financial
strength and technical and marketing resources, the Company's objective is to
concentrate its activities in markets in which its engineering capabilities and
the reliability of its products are recognized. The Company believes it is a
significant supplier in its selected product areas even though it faces strong
competition from other manufacturers, some of which utilize technology different
from that used by the Company.

                               PRINCIPAL CUSTOMERS

In fiscal years 1995 and 1994, sales of microelectronic products to one customer
accounted for approximately 21% and 27% respectively, of the Company's total
sales. Sales in this segment during 1995 to another customer also accounted for
approximately 12% of the Company's total sales. During fiscal year 1993, sales
of various electromechanical business segment products to the U.S. government
accounted for approximately 20 percent of the Company's total sales for that
year. No other customer accounted for 10 percent or more of the Company's total
sales in either business segment for such fiscal years. The majority of the
Company's sales in both business segments are made to the U.S. Government or to
U.S. Government prime contractors. These contracts tend to be for relatively
large dollar amounts, sometimes calling for deliveries over more than one year.
The award of new contracts or the expiration of old contracts could have a
significant short-term impact on sales and operating results.

                      RESEARCH, ENGINEERING AND DEVELOPMENT

Current research and product development activities are directed primarily
toward the improvement of existing standard products while some projects are
focused on the development of new products. Although the Company devotes a
minimal portion of its resources to pure research and development, the Company
emphasizes the application of its engineering expertise to the development and
refinement of proprietary products. Expenditures by the Company on research and
product development for fiscal years 1995, 1994 and 1993 amounted to
approximately $762,000, $593,000 and $272,000 respectively. The Company
principally utilizes its engineering staff in its research and development
efforts.

                            ENVIRONMENTAL PROTECTION

Compliance with federal, state and local laws or regulations which govern the
discharge of materials into the environment, has not had a material adverse
effect upon the capital expenditures, earnings or competitive position of the
Company.

                                    EMPLOYEES

As of September 30, 1995, the Company employed 204 persons. Of such employees,
92 were employed in the microelectronic segment, 107 in the electromechanical
segment and 5 were employed on the corporate staff. A total of 59 of the
Company's employees in the electromechanical segment were employed pursuant to
collective bargaining agreements covering workers at the Company's Technologies
division in Fort Wayne, Indiana. This agreement will expire on November 15,
1998. The Company believes its labor relations are satisfactory.

ITEM 7    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
          RESULTS OF OPERATIONS

Results of Operations

Fiscal 1995, 1994 and 1993 net sales were $26,869,000, $27,821,000 and
$20,101,000 respectively. The 3.4% decrease in net sales from 1994 to 1995 was
the result of a 10.5% decrease in sales in the electromechanical segment. The
decrease in sales in the electromechanical segment was primarily in the
mechanical and interface product lines, partially offset by increased ordnance
and rapid heat transfer sterilizer product lines. The increased sales in the
ordnance product line were positively impacted by a $435,000 claim settlement
recognized in the second quarter of fiscal 1995. Sales during fiscal 1995 in the
microelectronic segment were approximately equivalent to those in the prior
year. This segment experienced a decrease in custom military products which was
offset by an increase in the standard military memory product line. The 38.4%
increase in net sales from 1993 to 1994 was the result of a 137.4% increase in
sales in the microelectronic segment, partially offset by a 21.5% decrease in
sales in the electromechanical segment. Sales in the microelectronic segment
increased by approximately $10.4 million due primarily to a large order for high
density memories being utilized in the Abrams tank, as well as other new memory
products. Sales in the electromechanical segment decreased from 1993 to 1994 by
approximately $2.7 million due primarily to decreased sales in both ordnance and
systems products reflecting increased competitive pressures due to the decreased
level of procurement by the Department of Defense. Sales for the fourth quarter
of fiscal 1993 for the electromechanical segment included $1.9 million received
in settlement of an ordnance claim.

The Company continues to believe that changes in defense spending will not have
a material adverse affect on the Company's overall results. However, it appears
that although the Company's microelectronic segment of the Company's business
could experience growth as a result of changes in defense spending, the
Company's electromechanical segment could continue to be negatively impacted.
Accordingly, the Company continues to pursue its goal of reduced dependency on
the defense industry.

Gross margin, as a percentage of sales, increased slightly during fiscal 1995 to
37.8%. Gross margins in the microelectronic segment were approximately $8.0
million or 44.2% due to improving margins in the standard military memory
product line. Gross margins in the electromechanical segment were approximately
$2.2 million or 24.7% where margin percentages were down in each product line.
The gross margin for this segment was positively impacted by 5% due to the
recognition of the above noted ordnance claim settlement. Gross margins, as a
percent of sales, were 37.1% in fiscal 1994. Gross margins in the
microelectronic segment in 1994 were approximately $7.0 million or 38.9% due
primarily to the increased sales of high density memory products which have a
higher gross margin than other product lines. Gross margins in the
electromechanical segment in 1994 were approximately $3.3 millon or 33.8%.
Although sales in this segment had been down from the prior year, margins in the
mechanical and keyboard product lines increased over that year. Gross margins,
as a percent of sales, had decreased to 29.8% in fiscal 1993. This gross margin
percentage was 28.0% before giving effect to the gross margin of approximately
$900,000 derived from the settlement of a $1.9 million ordnance claim.

Selling, general and administrative expenses in fiscal 1995 were approximately
22.2% greater than those in fiscal 1994. This increase was principally due to
increased commissions, advertising and bonuses in the microelectronic segment,
to the writeoff in the third quarter of $236,000 in prepaid royalty payments and
increased marketing expenses both related to the Cox Sterile Products
acquisition, as well as to a $338,000 charge for the post employment benefits of
a former executive at the Company's headquarters. In fiscal 1994 selling,
general and administrative expense were greater than in 1993, due primarily to
increased commissions, marketing, and promotional support and bonus expenses in
the microelectronic segment, and increased advertising and selling expenses in
the electromechanical segment.

                                        7
<PAGE>   10
Product development expense in fiscal 1995 increased by $169,000 or 28% over
1994 due to increased spending on the rapid heat transfer sterilizer in the
electromechanical segment and new product development and research in the
microelectronic segment. Product development expense also increased in fiscal
1994 versus 1993. The increase, primarily in the electromechanical segment,
related to the development of prototypes of a high-definition, low-intensity
dental x-ray machine and the development of a sterilizing autoclave.

Interest expense in fiscal 1995 was approximately the same as in fiscal 1994,
due to decreased borrowing in 1995 which offset the effect of higher interest
rates. Interest expense in fiscal 1994 was approximately the same as in fiscal
1993. The effect of increased borrowing on interest expense was offset by
reduced overall interest rates on term debt and the write off, in 1993 (as
compared to 1994), of greater deferred debt issuance costs. The Company expects
that the lower rates under its new financing agreement will lower its overall
cost of financing in the near term.

Other income in fiscal 1995 consists of net rent proceeds from the Company's
leased facility in Acton, MA., offset primarily by the write-off of $319,000 of
goodwill associated with the Cox Sterile Products acquisition. In fiscal 1994,
other income consisted primarily of the net rent proceeds, offset by expenses
related to a dispute with a state taxing authority and the write-off of disputed
reimbursable costs on a third-party development contract. Other income in fiscal
1993 consisted primarily of net rent proceeds and gains on the disposition of
certain fixed assets.

During the third quarter of fiscal 1995, the Company recorded a $3.3 million tax
credit resulting from the elimination of the valuation allowance, as prescribed
by the provisions of Statement of Financial Accounting Standards No. 109,
related to the Company's deferred tax assets. As a result of this elimination,
the Company's effective tax rate in future years for financial statement
purposes will approximate the statutory rate. The Company is subject to the
alternative minimum tax which, when combined with state taxes, resulted in a
current tax provision of $200,000, $375,000 and $133,000 in fiscal 1995, 1994
and 1993, respectively. During the fourth quarter of fiscal 1994 the Company
recorded a tax liability of $176,000 after becoming aware of a potential
liability with regard to certain state income taxes for taxable years 1990
through 1994 as a result of a ruling by that state's supreme court. There have
been no tax assessments nor has the state audited the Company's tax returns for
those years.

FINANCIAL CONDITION, CAPITAL RESOURCES AND LIQUIDITY

Fiscal year-end 1995 working capital increased to $6,889,000 from $5,209,000 at
October 1, 1994. Included in this increase is $1,698,000 in current deferred tax
assets. Changes in the components of working capital are detailed in the
Company's Consolidated Statements of Cash Flows. The Company's current ratio at
fiscal year-end 1995 is approximately 2.3 to 1. Its total debt-to-equity ratio
improved to approximately 1.2 to 1.

Management believes that cash generated by operations, in addition to the
Company's borrowing capability, should be sufficient to fund the Company's cash
needs for the foreseeable future.

Subsequent to fiscal year-end 1995, the Company entered into a $10.7 million
financing agreement with Bank One Arizona, N.A. The financing agreement provides
for a two-year revolving line of credit facility of $4.0 million at 1% over the
Bank's prime rate, a five year term loan of $4.2 million at 1.25% over the
Bank's prime rate, an acquisition line of credit of $1 million at 1.5% over the
Bank's prime rate and a $1.5 million equipment leasing line of credit.
Approximately $2.1 million of the new term loan was used to pay the outstanding
term loan with Foothill Capital Corporation and approximately $1.8 million was
used to retire the balance of the Company's 13.5% convertible subordinated
debentures. The remaining financing is expected to be used for working capital,
equipment purchases and possible acquisitions.

                                        8
<PAGE>   11
The Company continues to seek a buyer for its land and building in Acton, MA,
and anticipates that proceeds from the sale would be in excess of the
obligations thereon.

The Company's capital expenditure plans are principally to expand manufacturing
capacity in the microelectronic segment and to improve the efficiency of the
manufacturing processes, and are expected to be financed largely through leasing
arrangements and, to a lesser extent, through funds provided from operations.

In fiscal 1995 and 1994, the Company generated $3,017,000 and $946,000,
respectively of cash from operating activities. Management anticipates that
operations will continue to generate cash in the foreseeable future. Management
also anticipates that for the near term its cash payments for Federal income
taxes will be based on rates applicable to the alternative minimum tax as it
uses its net operating loss carryforwards.

                 BOWMAR INSTRUMENT CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       SIGNIFICANT ACCOUNTING POLICIES

         a.    BASIS OF PRESENTATION

         The consolidated financial statements include the accounts of Bowmar
         Instrument Corporation and its subsidiaries (collectively the
         "Company"). All significant intercompany accounts and transactions are
         eliminated. Certain amounts in prior fiscal years consolidated
         financial statements have been reclassified to conform to current
         presentation.

         b.    CHANGE IN FISCAL YEAR-END

         The Company elected in fiscal 1993 to change its fiscal year-end from
         September 30 to the Saturday nearest September 30, in order to coincide
         the Company's year-end with the 4/4/5 week schedule of its operating
         units.

         c.    ACCOUNTS RECEIVABLE

         Accounts receivable have been reduced by an allowance for doubtful
         accounts of approximately $102,000 and $126,000 at fiscal year-end 1995
         and 1994, respectively.

         d.    INVENTORIES

         Inventories are stated at the lower of cost (principally first-in,
         first-out) or market. In accordance with industry practices,
         inventories may include amounts relating to contracts and programs with
         long production cycles, a portion of which is not expected to be
         realized within one year.

         e.    PROPERTY, PLANT AND EQUIPMENT

         Property, plant and equipment, including property under capital lease
         agreements, are stated at cost. Depreciation is determined on a
         straight-line basis over the estimated useful lives ranging from 5 to
         33 years for buildings and improvements and 3 to 10 years for machinery
         and equipment. Leasehold improvements are amortized over the lives of
         the leases or estimated useful lives of the assets, whichever is less.
         When assets are sold or otherwise retired, the cost and accumulated
         depreciation are removed from the books and the resulting gain or loss
         is included in operating results.

         f.    GOVERNMENT CONTRACTS

         Sales under government contracts are recorded when the units are
         shipped and accepted by the government. Applicable earnings are
         recorded pro rata based upon total estimated earnings at completion of
         the contracts; projected losses are provided for in their entirety when
         identified.

         g.    PRODUCT DEVELOPMENT

         Product development and tooling costs relating to specific customer
         orders are charged to expense as such orders are delivered.

                                       15
<PAGE>   20
         h.    INCOME TAXES

         The Company files a consolidated tax return with all of its
         wholly-owned subsidiaries. Temporary differences in the recognition of
         taxable income for financial reporting and income tax purposes relate
         primarily to the use of different depreciation methods and useful lives
         for tax purposes, the allowances for doubtful accounts and inventory
         obsolescence and the timing of reporting bonus expense.

         i.    NET INCOME PER COMMON SHARE

         Primary income per share is computed by deducting preferred dividends
         from net income to determine net income available to common
         shareholders. This amount is then divided by the weighted average
         number of common shares outstanding and common stock equivalents.
         Income per share assuming full dilution is determined by dividing net
         income by the weighted average number of common shares outstanding
         during the year after giving effect to common stock equivalents arising
         from stock options and preferred stock assumed converted to common
         stock.

         j.    ACCOUNTING STANDARD NOT ADOPTED

         The Company has not made a decision as to the date or method of
         adoption of Statement of Financial Accounting Standard No. 123
         "Accounting for Stock-Based Compensation" issued in October 1995.

2.       INVENTORIES

=====================================================================
</TABLE>

Under contractual arrangements by which progress payments are received on U.S.
Government subcontracts, title to inventories identified with related contracts
is vested in the government. Inventories were reduced by $40,000 in 1995 and
$140,000 in 1994 for such progress payments.

3.       OTHER ASSETS

Other assets include approximately $1,532,000 for certain land and buildings in
Acton, MA. The Company intends to sell this property which is presently leased
to the purchasers of the Bowmar/ALI Military Systems Division under an operating
lease agreement which extends through February 1997. Rental income during fiscal
years 1995, 1994 and 1993 was $552,000, $532,000 and $512,000, respectively.
Future minimum rentals due the Company under this lease are approximately
$572,000 in 1996 and $242,000 in the first five months of 1997. In fiscal 1994
other assets also included approximately $340,000 of goodwill related to the Cox
Sterile Products acquisition. This remaining goodwill was written off in the
third quarter of fiscal 1995 by a charge of $319,000 to other expense.

5.       NOTES PAYABLE

Notes payable at September 30, 1995, represent borrowings issued in conjunction
with an asset-based lending agreement with Foothill Capital Corporation
consisting of a credit line and term loans collateralized by the Company's
assets. Subsequent to the fiscal year-end the Company entered into a $10.7
million financing agreement with Bank One Arizona (see Note 6). The Foothill
lending agreement which expired November 15, 1995, had an authorized maximum
borrowing on the credit line of $4,000,000. The credit line bore interest at the
prime interest rate plus 2.75%, which was 11.5%, 10.5% and 9.25% at fiscal
year-end 1995, 1994 and 1993, respectively. The average interest rate for fiscal
years 1995, 1994 and 1993 was approximately 11.4%, 10.1%, and 9.8%,
respectively. The Company paid a commitment fee at a rate of 0.5% per annum on
the unused portion of the credit line.

The 13.5% convertible subordinated debentures and the Foothill Capital
Corporation term loan were retired in November 1995 from the proceeds of the
$10.7 million financing agreement with Bank One Arizona. As of September 30,
1995, the 13.5% convertible subordinated debentures and the Foothill Capital
Corporation term loan have been classified based on the terms of the new
financing agreement.

The Bank One financing provides for a two year revolving line of credit facility
in the principal amounts of $4.0 million at 1% over the Bank's prime rate; a
five year term loan in the principal amount of $4.2 million at 1.25% over the
Bank's prime rate; an acquisition line of credit of $1 million at 1.5% over the
Bank's prime rate and an equipment leasing line of credit of $1.5 million. The
Bank One financing is collateralized by all of the assets of the Company,
subject to the prior lien associated with the industrial revenue bonds.

The industrial revenue bonds are payable at the rate of $22,500 per quarter
through September 30, 2000, plus interest at the reference rate of the Fort
Wayne National Bank. The interest rate at September 30, 1995 was 6.6%. The bonds
are collateralized by real property with a net book value of $1,532,000 which is
included in other assets. At September 30, 1995, the Company was not in
compliance with certain covenants related to the industrial revenue bonds. The
sole holder of these bonds has consented to the Company's noncompliance with
these covenants through October 1, 1996, thereby effectively waiving compliance
through that date.

Based on terms of the industrial revenue bonds, obligations under capital leases
and the terms of the new Bank One financing agreement, the aggregate maturities
of the above term debt, including the interest portion of minimum lease payments
on capital leases, are approximately $661,000 in 1996, $550,000 in 1997,
$511,000 in 1998, $511,000 in 1999, and $2,420,000 in 2000.

7.       INCOME TAXES

The (credit) provision for income taxes consists of the following:

===============================================================================
</TABLE>

Based on the Company's recent pre-tax income and projections of future taxable
income over the period in which the deferred income tax assets are deductible,
the Company believes it will realize the benefit of the deferred tax assets. As
a result, during fiscal 1995, the Company recorded a $3.3 million tax credit
resulting from the elimination of the valuation allowance related to the
Company's deferred tax asset. There can be no assurance, however, that the
Company will generate a specific level of continued earnings.

During the fourth quarter of fiscal 1994, the Company became aware of a
potential liability with regard to certain state income taxes for taxable years
1990 through 1994 as a result of a ruling by that state's Supreme Court. There
have been no tax assessments nor has the state audited the Company's tax returns
for those years. The Company recorded an estimated liability of approximately
$176,000 in the fourth quarter of fiscal 1994.

As of September 30, 1995, the Company had federal net operating loss carryovers
for tax purposes of approximately $5,656,000 which expire from 2003 through
2005. Additionally, the Company has an alternative minimum tax credit of
approximately $82,000.

8.       BENEFIT PLANS

The Company has a defined benefit pension plan for employees at its Fort Wayne,
Indiana facility pursuant to a collective bargaining agreement. Benefits are
based primarily on a benefits multiplier and years of service. The Company funds
the amount equal to the minimum funding required plus additional amounts which
may be approved by the Company from time to time.

Net periodic pension cost included the following components:

and money market funds. The weighted-average assumed discount rate was 7.5% and
the long-term rate of return on assets was 7%.

In addition, the Company has an Incentive Savings 401(k) Plan covering
substantially all non-union employees of the Company who have completed six
months of service. During each of the fiscal years 1995, 1994 and 1993, the
Company made contributions to the plan of approximately $45,000, $58,000 and
$58,000 respectively.

9.       STOCK OPTIONS AND AWARDS

Under the Company's shareholder approved 1994 Flexible Stock Plan, common stock
is available for the grant of options, appreciation rights, restricted stock
awards, performance shares and other stock-based awards. At September 30, 1995,
30,583 shares were available for future grants to certain officers and employees
at prices not less than the fair market value at the date of grant determined by
the Board of Directors. At fiscal year-end 1995, 234,000 shares from the
Company's 1994 plan are under option.

During fiscal 1995, the Board of Directors terminated the Company's shareholder
approved 1986 Stock Option Plan. Shares from the Company's 1986 Plan remain
under option and are exercisable as early as one year after grant. At fiscal
year-end 1995, 66,000 shares from the Company's 1986 Plan are under option.

The Company's shareholder approved Non-Qualified Stock Option Plan for
Non-Employee Directors provides for 132,069 shares of common stock, for issuance
to non-employee directors, at an exercise price equal to the fair market value
on the date of issuance. The options are exercisable six months after date of
grant and expire in ten years. A total of 74,000 options under this
Non-Qualified Plan have been issued to non-employee directors and remain
unexercised at September 30, 1995.

The Company's shareholder approved Non-Qualified Option provides a non-qualified
option to purchase, for ten years, 275,000 shares of common stock at a price of
$1.375 per share, the closing price of the stock on August 15, 1991, the date on
which the options were granted to the Company's former President. The option is
100% vested. Of such options, 75,000 have been exercised leaving 200,000 shares
unexercised.

A summary of changes in outstanding options follows:

During fiscal 1995, the Board of Directors terminated the Company's Restricted
Stock Award Plan under which shares of the Company's common stock were available
to certain officers and employees without the payment of consideration. The cost
of such awards at the date of grant was considered to be compensation and is
being expensed over the vesting period. Amounts charged to expense in fiscal
years 1995, 1994 and 1993, net of forfeitures, were $40,000, $47,000, and
$12,000, respectively. At September 30, 1995, a total of 75,500 shares
previously awarded were restricted.

10.      COMMITMENTS AND CONTINGENCIES

The Company leases certain property and equipment under noncancelable lease
agreements some of which include renewal options of up to five years. Total rent
expense for 1995, 1994 and 1993 was $399,000, $202,000, and $256,000,
respectively. Future minimum annual fixed rentals required under noncancelable
operating leases having an original term of more than one year are $410,000 in
1996, $273,000 in 1997, $46,000 in 1998, $15,000 in 1999 and $8,000 in 2000.

During fiscal 1995 a claim for $435,000 was settled and recorded as a sale.
There were no costs associated with this claim. During fiscal 1993 a claim which
was settled for $1,900,000 was recorded as a sale. Deferred costs and the
expenses related to the settlement of the claim were recorded as cost of sales.
After giving effect to the costs and related income taxes the impact on fiscal
1993 net income was approximately $820,000.

11.      PREFERRED STOCK

Preferred shareholders vote equally with common shareholders. Each share of
preferred stock has one vote, is convertible into 13.33 shares of the Company's
common stock (stated value $0.10 per share), and pays annual dividends totaling
$3.00, payable quarterly on March 31, June 30, September 30 and December 31 of
each year. The preferred stock is redeemable at the option of the Company at
$25.00 per share on and after January 1, 1998, and is not subject to mandatory
redemption.

12.      CONCENTRATIONS OF CREDIT RISK

The Company sells its products primarily to the defense and commercial
industries in the United States. The Company performs ongoing credit evaluations
of its customers' financial condition and, generally, requires no collateral
from its customers. At certain times throughout the year the Company may
maintain certain bank accounts in excess of the FDIC insured limits.

13.      BUSINESS SEGMENTS

The Company operates in two industry segments. These segments are the
manufacture and sale of (1) electromechanical and mechanical equipment and
components, which include electromechanical display devices, electromechanical
components and packages, keyboards and related subsystems and ordnance; and (2)
microelectronic equipment and components, which include high density solid state
memory modules and multichip microcircuits.

A significant portion of the Company's business activity in each business
segment is conducted either directly with, or as a subcontractor to entities
having contracts with, the United States Department of Defense. As of September
30, 1995 and October 1, 1994, the Company's receivables from such customers were
approximately $3,000,000 and $3,189,000, respectively. Certain major customers
made up at least 10% of total Company sales in each of the last three fiscal
years. Sales to one customer of the electromechanical segment were 20% of total
Company sales for fiscal year 1993, while sales to one customer of the
microelectronic segment in fiscal 1995 and 1994 were 21% and 27%, respectively.
Sales to another customer of the microelectronic segment in 1995 were 11% of
total company sales.

Sales for each business segment are principally to unaffiliated customers.
Intersegment sales are not significant. Assets identifiable to industry segments
are those assets which are used in the Company's operations and do not include
general corporate assets. General corporate assets consist primarily of cash,
furniture and fixtures, unamortized debt issue costs and the deferred income tax
assets.

                        REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF BOWMAR INSTRUMENT CORPORATION

We have audited the consolidated financial statements of Bowmar Instrument
Corporation and Subsidiaries as of September 30, 1995 and October 1, 1994, and
for each of the three years in the period ended September 30, 1995, as listed in
Item 14(a) of this Form 10-K. 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.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Bowmar
Instrument Corporation and Subsidiaries as of September 30, 1995 and October 1,
1994, and the results of their operations and their cash flows for each of the
three years in the period ended September 30, 1995, in conformity with generally
accepted accounting principles.

               (b) All accrued interest shall be due and payable on each Payment
         Date prior to the Acquisition Termination Date.

         Conversion Rate, monthly installments of interest and principal shall
         be due and payable on each Payment Date each in a principal amount
         sufficient to amortize the principal balance outstanding on

         the Acquisition Conversion Date over sixty (60) equal monthly
         installments, plus all accrued and unpaid interest.

               (d) Should Borrower elect that the Acquisition Note bear interest
         at the Acquisition Conversion Rate, equal payments of principal and
         interest shall be due and payable in consecutive monthly installments
         commencing on the first Payment Date after the Acquisition Conversion
         Date, and continuing on each Payment Date thereafter, each in an amount
         sufficient to fully amortize the principal amount of the Acquisition
         Note outstanding on the Acquisition Conversion Date, at the Acquisition
         Conversion Rate, over an amortization period equal to number of months
         remaining until the Acquisition Maturity Date.

               (f) If any payment required under the Acquisition Note is not
         paid within fifteen (15) days after the date such payment is due, then,
         at the option of Lender, Borrower shall pay a "late charge" equal to
         four percent (4%) of the amount of that payment to compensate Lender
         for administrative expenses and other costs of delinquent payments.
         This late charge may be assessed without notice, shall be immediately
         due and payable and shall be in addition to all other rights and
         remedies available to Lender.

               (g) After maturity, including maturity upon acceleration, the
         unpaid principal balance, all accrued and unpaid interest and all other
         amounts payable under the Acquisition Note shall bear interest at the
         Default Rate.

shall not be waived or released thereby. Borrower shall be and continue to be

transfer, voluntary or involuntary, of this Loan Agreement or any right
hereunder shall not be binding upon or in any way affect Lender without its
written consent; Lender may make Acquisition Advances under the disbursement

         5.1   RLC Fee. In connection with the RLC, Lender has earned and 
Borrower shall pay to Lender on or before the Closing Date a non-refundable RLC
Fee (the "RLC Fee") in the amount of $12,500.00. Borrower acknowledges that the

Borrower to Lender.

         5.2   Unused RLC Fee. An unused RLC fee (the "Unused RLC Fee") computed
at the rate of one-quarter of one percent (.25%) per annum on the unused portion
of the RLC Commitment, calculated from the date hereof shall be payable monthly
in arrears. For each month (or portion thereof), the unused commitment fee shall
be equal to (A) the RLC Commitment minus (B) the "average monthly outstandings"

being computed, with the resulting number multiplied by (C) one-twelfth (1/12th)
of the rate per annum set forth above. As used herein, "average monthly
outstandings" means the sum of the outstanding amount of the RLC Advances on
each day during the month (or portion thereof for which the Unused RLC Fee is
being computed) with respect to which the Unused RLC Fee is being computed,
divided by the number of days in that month (or portion thereof). If the Unused
RLC Fee is being computed for less than a full month, the percentage used in
clause (C) above shall be computed on a daily basis for the number of days for
which the fee is being computed.

Borrower shall pay to Lender on or before the Closing Date a non-refundable Term
Loan fee (the "Loan Fee") in the amount of $12,500.00. Borrower acknowledges

previously paid by Borrower to Lender.

                         REPRESENTATIONS AND WARRANTIES

         To induce Lender to make the Loans, Borrower represents and warrants to
Lender that:

         8.1   Organization and Good Standing. It is duly organized in the State
of Indiana, validly existing and in good standing in the State of Indiana and is
duly qualified to do business in the States of Arizona and Indiana. It has the
legal power and authority to own its properties and assets and to transact the
business in which it is engaged and is or will be qualified in those states
wherein the nature of its proposed business and property will make such
qualifications necessary or appropriate in the future.

         8.2   Authorization and Power. It has the corporate power and requisite
authority to execute, deliver and perform this Loan Agreement, the Notes and the
other Loan Documents to be executed by it; it is duly authorized to, and has
taken all action, corporate or otherwise, necessary to authorize it to, execute,
deliver and perform this Loan Agreement, the Notes and such other Loan Documents
and is and will continue to be duly authorized to perform this Loan Agreement,
the Notes and such other Loan Documents.

         8.3   No Conflicts or Consents. Neither the execution and delivery of
this Loan Agreement, the Notes or the other Loan Documents to which it is a
party, nor the consummation of any of the transactions herein or therein
contemplated, nor compliance with the terms and provisions hereof or with the
terms and provisions thereof, (a) will materially contravene or conflict with:
(i) any provision of law, statute or regulation to which it is subject, (ii) any
judgment, license, order or permit applicable to it, or (iii) any indenture,
loan agreement, mortgage, deed of trust, or other agreement or instrument to
which it is a party or by which it may be bound, or to which it may be subject,
or (b) will violate any provision of its Articles of Incorporation. No consent,
approval, authorization or order of any court or Governmental Authority or other
Person is required in connection with the execution and delivery by it of the
Loan Documents or to consummate the transactions contemplated hereby or thereby,
or if required, such consent, approval, authorization or order shall have been
obtained.

         8.4   Enforceable Obligations. This Loan Agreement, the Notes and the
other Loan Documents are the legal, valid and binding obligations of Borrower,
enforceable against Borrower in accordance with their respective terms, except
as limited by bankruptcy, insolvency or other laws or equitable principles of
general application relating to the enforcement of creditors' rights.

         8.5   Financial Condition. Borrower has delivered to Lender copies of
the Borrower's most recent audited financial statements. Such financial
statements, in all material respects, fairly present the financial position of
Borrower as of such date and have been prepared in accordance with GAAP. Since
the date thereof, Borrower has not discovered any obligations, liabilities or
indebtedness (including contingent and indirect liabilities and obligations or
unusual forward

                                      -27-

or long-term commitments) which in the aggregate are material and adverse to the
financial position or business of Borrower that should have been but were not
reflected in such financial statements. No changes having a Material Adverse
Effect have occurred in the financial condition or business of Borrower since
the date of the latest financial statements delivered to Lender.

         8.6   Full Disclosure. There is no material fact known to Borrower that
it has not disclosed to Lender that would have a Material Adverse Effect. No
certificate or statement delivered herewith or heretofore by it to Lender in
connection with negotiations of this Loan Agreement, contains any untrue
statement of a material fact or omits to state any material fact necessary to
keep the statements contained herein or therein from being misleading.

         8.7   No Default. No event or condition has occurred and is continuing
that constitutes an Event of Default.

         8.8   Significant Debt Agreements. It is not in default in any material
respect under any Significant Debt Agreement.

         8.9   No Litigation. There are no actions, suits or legal, equitable,
arbitration or administrative proceedings pending, or to its actual knowledge
overtly threatened, against Borrower that would, if adversely determined, have a
Material Adverse Effect.

         8.10  Taxes. It has filed or caused to be filed all returns and reports
which are required to be filed by any jurisdiction, and has paid or made
provision for the payment of all taxes, assessments, fees or other governmental
charges imposed upon its properties, income or franchises, as to which the
failure to file or pay would have a Material Adverse Effect, except such
assessments or taxes, if any, which are being contested in good faith by
appropriate proceedings.

         8.11  ERISA. (a) No Reportable Event has occurred and is continuing 
with respect to any Plan; (b) PBGC has not instituted proceedings to terminate
any Plan; (c) neither the Borrower, any member of the Controlled Group, nor any
duly-appointed administrator of a Plan (i) has incurred any liability to PBGC

has instituted or intends to institute proceedings to terminate any Plan under
Section 4041 or 4041A of ERISA; and (d) each Plan of Borrower has been
maintained and funded in all material respects in accordance with its terms and
in all material respects in accordance with all provisions of ERISA applicable
thereto. Neither the Borrower nor any of its Subsidiaries participates in, or is
required to make contributions to, any Multi-employer Plan (as that term is
defined in Section 3(37) of ERISA).

         8.12  Compliance with Law. It is in substantial compliance with all
laws, rules, regulations, orders and decrees that are applicable to it, or its
properties, noncompliance with which would have a Material Adverse Effect.

         8.13  Survival of Representations, Etc. All representations and
warranties by Borrower herein shall survive the making of the Loans and the
execution and

                                      -28-
<PAGE>   29

Lender shall not diminish Lender's right to rely on the representations and
warranties herein.

         8.14  Recitals. The recitals and statements of intent appearing in this
Loan Agreement are true and correct.

         8.15  No Stock Purchase. No part of the proceeds of any financial
accommodation made by Lender in connection with this Loan Agreement will be used
to purchase or carry "margin stock," as that term is defined in Regulation U, or
to extend credit to others for the purpose of purchasing or carrying such margin
stock.

         8.16  Solvency. It (both before and after giving effect to the Loan
contemplated hereby) is solvent, has assets having a fair value in excess of the
amount required to pay its probable liabilities on its existing debts as they
become absolute and matured, and has, and will have, access to adequate capital
for the conduct of its business and the ability to pay its debts from time to
time incurred in connection therewith as such debts mature.

         8.17  Advances. Each request for an Advance or for the extension of any
financial accommodation by Lender whatsoever shall constitute an affirmation
that the representations and warranties contained herein are, true and correct
as of the time of such request. All representations and warranties made herein
shall survive the execution of this Loan Agreement, all advances of proceeds of
the Loans and the execution and delivery of all other documents and instruments
in connection with the Loans and/or this Loan Agreement, so long as Lender has
any commitment to lend hereunder and until the Loans have been paid in full and
all of Borrower's obligations under this Loan Agreement, the Notes and all
Security Documents have been fully discharged.

Collateral, free of any Liens except for Permitted Liens, if any.

         8.19  Security Documents. The liens, security interests and assignments

enforceable liens, security interests and assignments, except to the extent (if
any) otherwise agreed in writing by Lender.

any business or operations other than Bowmar/ALI.

set forth in Article 7 hereof the representations and warranties contained in
Sections 8.3, 8.8, 8.18 and 8.19 are subject to conflicts arising under, and the
effect of, Borrower's agreements with Foothill Capital Corporation.

         herein, or in any of the other Loan Documents (other than a failure or
         neglect described in one or more provisions of this Section 11.1) and
         such failure or neglect continues unremedied for a period of thirty
         (30) days after notice thereof to Borrower;

               (c) Any material warranty, representation or statement contained

         or shall prove to have been false when made or furnished;

               (d) The occurrence of any material "event of default" or
         "default" by Borrower under any agreement, now or hereafter existing,

         declared to be due and payable, or required to be prepaid (other than
         by a regularly scheduled prepayment), prior to the stated maturity

               (g) Borrower shall (i) apply for or consent to the appointment of

         effecting any of the foregoing;

               (h) An involuntary petition or complaint shall be filed against

         covered by insurance where coverage has been acknowledged by the
         insurer) shall be rendered against Borrower, and such judgment or
         judgments shall not be satisfied, settled, bonded or discharged at

         any such Plan shall be terminated, in each case under Section 4041 or
         4042 of ERISA, and such termination shall give rise to a liability of
         the Borrower or the Controlled Group to the PBGC or the Plan under
         ERISA having an effect in excess of $200,000.00 or (ii) a Reportable
         Event, the occurrence of which would cause the imposition of a lien in
         excess of $200,000.00 under

                                      -38-
<PAGE>   39
         Section 4062 of ERISA, shall have occurred with respect to any Plan
         (other than a Multi-Employer Pension Plan as that term is defined in
         Section 4001(a)(3) of ERISA) and be continuing for a period of sixty
         (60) days;

               (k) Any of the following events shall occur with respect to any
         Multi-Employer Pension Plan (as that term is defined in Section
         4001(a)(3) of ERISA) to which Borrower contributes or contributed on
         behalf of its employees and Lender determines in good faith that the
         aggregate liability likely to be incurred by Borrower, as a result of
         any of the events specified in Subsections (i), (ii) and (iii) below,
         will have an effect in excess of $200,000.00; (i) Borrower incurs a
         withdrawal liability under Section 4201 of ERISA; (ii) any such plan is
         "in reorganization" as that term is defined in Section 4241 of ERISA;
         or (iii) any such Plan is terminated under Section 4041A of ERISA;

               (l) The occurrence of a Change in Control without the written
         consent of Lender;

               (m) The dissolution, liquidation, sale, transfer, lease or other
         disposal of all or substantially all of the assets or business of
         Borrower;

               (n) Any levy or execution upon, or judicial seizure of, any
         property of Borrower that has a fair market value in excess of
         $200,000.00 that is not bonded or released within forty-five (45) days;

               (o) The occurrence of either any material adverse change in the
         financial condition of Borrower or a material change in the management
         of Borrower, in either case that Lender, in its reasonable discretion,
         deems material, or if Lender in good faith shall believe that the
         prospect of payment or performance of the Loan is impaired; or

               (p) Any failure of Bowmar/ALI to make payments when due under the
         indebtedness secured by the Acton Lien.

         11.2  Remedies Upon Event of Default. If an Event of Default shall have
occurred and be continuing, then Lender may, at its sole option, exercise any
one or more of the following rights and remedies, and any other remedies
provided in any of the Loan Documents, as Lender in its sole discretion may deem
necessary or appropriate, all of which remedies shall be deemed cumulative, and
not alternative: (i) cease making Advances or extensions of financial
accommodations in any form to or for the benefit of Borrower and declare the
principal of, and all interest then accrued on, the Notes and any other
liabilities hereunder to be forthwith due and payable, whereupon the same shall
become immediately due and payable without presentment, demand, protest, notice
of default, notice of acceleration or of intention to accelerate or other notice
of any kind all of which Borrower hereby expressly waives, anything contained
herein or in the Notes

                                      -39-
<PAGE>   40
to the contrary notwithstanding, (ii) reduce any claim to judgment, and/or (iii)
without notice of default or demand, pursue and enforce any of Lender' rights
and remedies under the Loan Documents, or otherwise provided under or pursuant
to any applicable law or agreement; provided, however, that if any Event of
Default specified in Sections 11.1(g) and 11.1(h) shall occur, the principal of,
and all interest on, the Notes and other liabilities hereunder shall thereupon
become due and payable concurrently therewith, without any further action by
Lender and without presentment, demand, protest, notice of default, notice of
acceleration or of intention to accelerate or other notice of any kind, all of
which Borrower hereby expressly waives.

         Upon the occurrence and during the continuance of any Event of Default,
Lender is hereby authorized at any time and from time to time, without notice to
Borrower (any such notice being expressly waived by Borrower), to set off and
apply any and all moneys, securities or other property of Borrower and the
proceeds therefrom, now or hereafter held or received by or in transit to Lender
or its agents, from or for the account of Borrower, whether for safe keeping,
custody, pledge, transmission, collection or otherwise, and also upon any and
all deposits (general or special) and credits of Borrower, and any and all
claims of Borrower against Lender at any time existing. Lender agrees promptly
to notify Borrower after any such setoff and application, provided that the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of Lender under this Section 11.2 are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which Lender may have.

         11.3  Performance by Lender. Should Borrower fail to perform any
covenant, duty or agreement with respect to the payment of taxes, obtaining
licenses or permits, or any other requirement contained herein or in any of the
Loan Documents within the period provided herein, if any, for correction of such
failure, Lender may, at its option, perform or attempt to perform such covenant,
duty or agreement on behalf of Borrower. In such event, Borrower shall, at the
request of Lender, promptly pay any amount expended by Lender in such
performance or attempted performance to Lender at its main office in Phoenix,
Arizona, together with interest thereon at the Default Rate, from the date of
such expenditure until paid. Notwithstanding the foregoing, it is expressly
understood that Lender does not assume any liability or responsibility for the
performance of any duties of Borrower hereunder or under any of the Loan
Documents or other control over the management and affairs of Borrower.

                                  MISCELLANEOUS

         12.1  Modification. All modifications, consents, amendments or waivers
of any provision of any Loan Document, or consent to any departure by Borrower
therefrom, shall be effective only if the same shall be in writing and accepted
by Lender.

         12.2  Waiver. No failure to exercise, and no delay in exercising, on 
the part of Lender, any right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise thereof preclude any other further exercise
thereof or the exercise of any other right. The rights of Lender hereunder and
under the Loan Documents shall be in addition to all other rights provided by
law. No modification or waiver of any provision of this Loan Agreement, the
Notes or any Loan Documents, nor consent to departure therefrom, shall be
effective unless in writing and no such consent or waiver shall extend beyond
the particular case and purpose involved. No notice or demand given in any case
shall constitute a waiver of the right to take other action in the same, similar
or other instances without such notice or demand.

         12.3  Payment of Expenses. Borrower shall pay all costs and expenses of
Lender (including, without limitation, the attorneys' fees of Lender's legal
counsel) incurred by Lender in connection with the documentation of the Loans,
and the preservation and enforcement of Lender's rights under this Loan
Agreement, the Notes, and/or the other Loan Documents, as well as the costs of
the Real Property appraisal and any updates thereof, the surveys, the title
insurance policies, any environmental reports and any filing and recording fees;
provided, however, that notwithstanding the aforesaid, with respect to any legal
action between the parties hereto that is pursued to judgment the prevailing
party only shall be reimbursed by the other party for all costs and expenses
(including, without limitation, reasonable attorneys' fees and costs) incurred
in connection with the preservation and enforcement of its rights under this
Loan Agreement, the Notes and/or other Loan Documents. Lender shall have the
right to require reappraisals of the Real Property at Borrower's expense. In
addition, Borrower shall pay all costs and expenses of Lender in connection with
the negotiation, preparation, execution and delivery of any and all amendments,
modifications and supplements of or to this Loan Agreement, the Notes or any
other Loan Document.

         12.4  Notices. Except for telephonic notices permitted herein, any

executed and delivered, and is intended to be performed in the State of Arizona.
The substantive laws of the State of Arizona and the applicable federal laws of
the United States of America shall govern the validity, construction,
enforcement and interpretation of this Loan Agreement and all of the other Loan
Documents, without regard to Arizona conflicts of law rules.

         12.6  Invalid Provisions. If any provision of any Loan Document is held
to be illegal, invalid or unenforceable under present or future laws during the
term of this Loan Agreement, such provision shall be fully severable; such Loan
Document shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part of such Loan Document; and
the remaining provisions of such Loan Document shall remain in full force and
effect and shall not be affected by the illegal, invalid or unenforceable
provision or by its severance from such Loan Document. Furthermore, in lieu of
each such illegal, invalid or unenforceable provision there shall be added as
part of such Loan Document a provision mutually agreeable to Borrower and Lender
as similar in terms to such illegal, invalid or unenforceable provision as may
be possible and be legal, valid and enforceable.

         12.7  Binding Effect. The Loan Documents shall be binding upon and 
inure to the benefit of Borrower and Lender and their respective successors,

or obligations thereunder.

         12.8  Entirety. The Loan Documents embody the entire agreement between
the parties and supersede all prior agreements and understandings, if any,
relating to the subject matter hereof and thereof.

herein shall survive delivery of the Notes and the making of the Loans.

         12.11 No Third Party Beneficiary. The parties do not intend the
benefits of this Loan Agreement to inure to any third party, nor shall this Loan
Agreement be construed to make or render Lender liable to any materialman,
supplier, contractor, subcontractor, purchaser or lessee of any property owned
by Borrower, or for debts or claims accruing to any such persons against
Borrower. Notwithstanding anything contained herein or in the Notes, or in any
other Loan Document, or any conduct or course of conduct by any or all of the
parties hereto, before or after signing this Loan Agreement or any of the other
Loan Documents, neither this Loan Agreement nor any other Loan Document shall be
construed as creating any right, claim or cause of action against Lender, or any
of its officers, directors, agents or employees, in favor of any materialman,
supplier, contractor, subcontractor, purchaser or lessee of any property owned
by Borrower, nor to any other person or entity other than Borrower.

         12.12 Schedules and Exhibits Incorporated. All schedules and exhibits
attached hereto are hereby incorporated into this Loan Agreement by each
reference thereto as if fully set forth at each such reference.

         12.13 Counterparts. This Loan Agreement may be executed in multiple
counterparts, each of which, when so executed, shall be deemed an original but
all such counterparts shall constitute but one and the same agreement.

         12.14 Securities Laws. Lender understands that Borrower is a public
company listed on the American Stock Exchange and is subject to various Federal
and state securities laws. Lender understands that Borrower will be furnishing

agents are, or will be made aware of, their obligations with respect to that
information under those securities laws.

      time to time reduced and thereafter increased or entirely extinguished and
      thereafter reincurred;

except if any portion of the Collateral is as of the date hereof intended to be

the "Obligation."

4.    REPRESENTATIONS AND WARRANTIES OF DEBTOR

      Debtor hereby represents and warrants that:

      4.1 If Debtor is a corporation, limited liability company, partnership or
trust, it (i) is duly organized, validly existing and in good standing under the
laws of the state in which it is organized; (ii) is qualified to do business and
is in good standing under the laws of the state in which the Collateral is
located and in each state in which it is doing business; (iii) has full power
and authority to own its properties and assets and to carry on its businesses as
now conducted; and (iv) is fully authorized and permitted to execute and deliver
this Agreement and to enter into any transactions evidenced by any portion of
the Collateral. Subject to Debtor's obligations to Foothill Capital Corporation
("Foothill"), which obligations will be terminated prior to the initial advance
under the Note, the execution, delivery and performance by Debtor of this
Agreement and all other documents and instruments relating to the Obligation
will not result in any breach of the terms and conditions or constitute a
default under any agreement or instrument under which Debtor is a party or is
obligated. Debtor is not in default in the performance or observance of any
covenants, conditions or provisions of any such agreement or instrument.

      4.2 Subject to security interests in favor of Foothill, which security
interests will be released prior to the initial advance under the Note, Debtor
is the owner of the Collateral free of all security interests or other
encumbrances except the Security Interest and no financing statement covering
the Collateral is filed or recorded in any public office, other than Permitted
Liens (as defined in the Loan Agreement).

      4.3 The Collateral is, and is intended to be, used, produced or acquired
by Debtor for use primarily for the purpose marked in Section 3 above. The
address of Debtor set forth at the beginning of this Agreement is the chief
executive office of Debtor or Debtor's residence if Debtor is an individual
without an office. If a portion of the Collateral is or will become a fixture,
it will be affixed to real property covered by a mortgage executed by Debtor in
favor of Secured Party.

      4.4 Each account, chattel paper or general intangible included in the
Collateral is genuine and enforceable in accordance with its terms against the
party named therein who is obligated to pay the same (hereinafter called
"Obligor"), and the security interests that are part of each item of chattel
paper included in the Collateral are valid, first and prior perfected security
interests. Each Obligor is solvent, and the amount that Debtor has represented
to Secured Party as owing by each Obligor is the amount actually and
unconditionally owing by that Obligor, without deduction except for normal cash
discounts where applicable; no Obligor has any defense, setoff, claim or

                                       -4-


<PAGE>   5










counterclaim against Debtor that can be asserted against Secured Party whether
in any proceeding to enforce the Security Interest or otherwise. Each document,
instrument and chattel paper included in the Collateral is complete and regular
on its face and free from evidence of forgery or alteration. No default has
occurred in connection with any instrument, document or chattel paper included
in the Collateral, no payment in connection therewith is overdue and no
presentment, dishonor or protest has occurred in connection therewith.

5.    COVENANTS OF DEBTOR

      5.1 Debtor shall not sell, transfer, assign or otherwise dispose of any
Collateral or any interest therein (except as permitted herein), with an
aggregate value in excess of $50,000.00 during any fiscal year, without
obtaining the prior written consent of Secured Party and, after the initial
advance under the Note, shall keep the Collateral free of all security interests
or other encumbrances except the Security Interest and Permitted Liens. Although
proceeds of Collateral are covered by this Agreement, this shall not be
construed to mean that Secured Party consents to any sale of the Collateral.

      5.2 Debtor shall keep and maintain the Collateral in good condition and
repair and shall not use the Collateral in violation of any provision of this
Agreement or any applicable statute, ordinance or regulation or any policy of
insurance insuring the Collateral.

      5.3 Debtor shall provide and maintain insurance insuring the Collateral
against risks, with coverage and in form and amount satisfactory to Secured
Party. At Secured Party's request, Debtor shall deliver to Secured Party the
original policies of insurance containing endorsements naming Secured Party as a
loss payee.

      5.4 Debtor shall pay when due all taxes, assessments and other charges
which may be levied or assessed against the Collateral; provided, that, upon
Notice to Secured Party, Debtor shall have the right to reasonably contest such
items in accordance with applicable law.

      5.5 Debtor shall prevent any portion of the Collateral that is not a
fixture from being or becoming a fixture and shall prevent any portion of the
Collateral from being or becoming an accession to other goods that are not part
of the Collateral.

      5.6 If the Collateral includes motor vehicles, Debtor shall provide
Secured Party with the license numbers of all titled vehicles, shall cause the
Security Interest to be shown as a valid first lien on the Certificate of Title
for all titled vehicles and shall deliver lien filing receipts to Secured Party
as evidence thereof.

      5.7 Debtor, upon demand, shall promptly deliver to Secured Party all
instruments, documents and chattel paper included in the Collateral and all

                                       -5-


<PAGE>   6










invoices, shipping or delivery records, purchase orders, contracts or other
items related to the Collateral. Debtor shall notify Secured Party immediately
of any default by any Obligor in the payment or performance of its obligations
with respect to any Collateral. Debtor, without Secured Party's prior written
consent, shall not make or agree to make any alteration, modification or
cancellation of, or substitution for, or credit, adjustment or allowance on, any
Collateral.

      5.8 Debtor shall give Secured Party immediate written notice of any change
in the location of: (i) Debtor's chief executive office (or residence if Debtor
is an individual without an office); (ii) the Collateral or any part thereof; or
(iii) Debtor's records concerning the Collateral.

      5.9 Secured Party or its agents may inspect the Collateral at reasonable
times and may enter into any premises where the Collateral is or may be located.
Debtor shall keep records concerning the Collateral in accordance with generally
accepted accounting principles and, upon the occurrence of an Event of Default,
shall mark its records and the Collateral to indicate the Security Interest.
Secured Party shall have free and complete access to Debtor's records and shall
have the right to make extracts therefrom or copies thereof. Upon request of
Secured Party from time to time, Debtor shall submit up-to-date schedules of the
items comprising the Collateral in such detail as Secured Party may require and
shall deliver to Secured Party confirming specific assignments of all accounts,
instruments, documents and chattel paper included in the Collateral.

      5.10 Debtor, at its cost and expense, shall protect and defend this
Agreement, all of the rights of Secured Party hereunder, and the Collateral
against all claims and demands of other parties, including without limitation
defenses, setoffs, claims and counterclaims asserted by any Obligor against
Debtor and/or Secured Party. Debtor shall pay all claims and charges that in the
opinion of Secured Party might prejudice, imperil or otherwise affect the
Collateral or the Security Interest. Debtor shall promptly notify Secured Party
of any levy, distraint or other seizure by legal process or otherwise of any
part of the Collateral and of any threatened or filed claims or proceedings that
might in any way affect or impair the terms of this Agreement.

      5.11 The Security Interest, at all times after the initial advance under
the Note, shall be perfected and shall be prior to any other interests in the
Collateral, other than Permitted Liens. Debtor shall act and perform as
necessary and shall execute and file all security agreements, financing
statements, continuation statements and other documents requested by Secured
Party to establish, maintain and continue the perfected Security Interest.
Debtor, on demand, shall promptly pay all costs and expenses of filing and
recording, including the costs of any searches, deemed necessary by Secured
Party from time to time to establish and determine the validity and the
continuing priority of the Security Interest.

                                       -6-


<PAGE>   7










      5.12 If Debtor shall fail to pay any taxes, assessments, expenses or
charges, to keep all of the Collateral free from other security interests,
encumbrances or claims, to keep the Collateral in good condition and repair, to
procure and maintain insurance thereon, or to perform otherwise as required
herein, Secured Party may, upon thirty (30) days notice to Debtor (unless
Secured Party determines an emergency exists in which case no notice shall be
required), advance the monies necessary to pay the same, to accomplish such
repairs, to procure and maintain such insurance or to so perform; Secured Party
is hereby authorized to enter upon any property in the possession or control of
Debtor for such purposes.

      5.13 All rights, powers and remedies granted Secured Party herein, or
otherwise available to Secured Party, are for the sole benefit and protection of
Secured Party, and Secured Party may exercise any such right, power or remedy at
its option and in its sole and absolute discretion without any obligation to do
so. In addition, if under the terms hereof, Secured Party is given two or more
alternative courses of action, Secured Party may elect any alternative or
combination of alternatives at its option and in its sole and absolute
discretion. All monies advanced by Secured Party under the terms hereof and all
amounts paid, suffered or incurred by Secured Party in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by the Security Interest, shall bear interest at
the highest rate payable on any of the Obligation until paid, and shall be due
and payable by Debtor to Secured Party immediately without demand.

6.    NOTIFICATION AND PAYMENTS; COLLECTION OF COLLATERAL; USE OF COLLATERAL BY
      DEBTOR

      6.1 Secured Party, after the occurrence of any Event of Default, defined
below, and without notice to Debtor, may notify any or all Obligors of the
existence of the Security Interest and may direct the Obligors to make all
payments on the Collateral to Secured Party. Until Secured Party has notified
the Obligors to remit payments directly to it, Debtor, at Debtor's own cost and
expense, shall collect or cause to be collected the accounts and monies due
under the accounts, documents, instruments and general intangibles or pursuant
to the terms of the chattel paper. Secured Party shall not be liable or
responsible for any embezzlement, conversion, negligence or default by Debtor or
Debtor's agents with respect to such collections; all agents used in such
collections shall be agents of Debtor and not agents of Secured Party. Unless
Secured Party notifies Debtor in writing that it waives one or more of the
requirements set forth in this sentence, after the occurrence of any Event of
Default, any payments or other proceeds of Collateral received by Debtor, before
or after notification to Obligors, shall be held by Debtor in trust for Secured
Party in the same form in which received, shall not be commingled with any
assets of Debtor and shall be turned over to Secured Party not later than the
next business day following the day of receipt. All payments and other proceeds
of Collateral received by Secured Party directly or from Debtor shall be applied
to the Obligation in such order and manner and at such time as Secured Party, in
its sole discretion, shall

                                       -7-


<PAGE>   8










determine. In addition, Debtor shall promptly notify Secured Party of the return
to or possession by Debtor of goods underlying any Collateral; Debtor shall hold
the same in trust for Secured Party and shall dispose of the same as Secured
Party directs.

      6.2 Secured Party, before or after the occurrence of an Event of Default
and without notice to Debtor, may demand, collect and sue on the Collateral
(either in Debtor's or Secured Party's name), enforce, compromise, settle or
discharge the Collateral and endorse Debtor's name on any instruments,
documents, or chattel paper included in or pertaining to the Collateral; Debtor
hereby irrevocably appoints Secured Party its attorney in fact for all such
purposes.

      6.3 Until the occurrence of an Event of Default, Debtor may: (i) use,
consume and sell any inventory included in the Collateral in any lawful manner
in the ordinary course of Debtor's business provided that all sales shall be at
commercially reasonable prices; and (ii) subject to Paragraphs 6.1 and 6.2
above, retain possession of any other Collateral and use it in any lawful manner
consistent with this Agreement.

7.    COLLATERAL IN THE POSSESSION OF SECURED PARTY

      7.1 Secured Party shall use such reasonable care in handling, preserving
and protecting the Collateral in its possession as it uses in handling similar
property for its own account. Secured Party, however, shall have no liability
for the loss, destruction or disappearance of any Collateral unless there is
affirmative proof of a lack of due care; the lack of due care shall not be
implied solely by virtue of any loss, destruction or disappearance.

      7.2 Debtor shall be solely responsible for taking any and all actions to
preserve rights against all Obligors; Secured Party shall not be obligated to
take any such actions whether or not the Collateral is in Secured Party's
possession. Debtor waives presentment and protest with respect to any instrument
included in the Collateral on which Debtor is in any way liable and waives
notice of any action taken by Secured Party with respect to any instrument,
document or chattel paper included in any Collateral that is in the possession
of Secured Party.

8.    EVENTS OF DEFAULT; REMEDIES

      8.1   The occurrence of any of the following events or conditions shall
constitute and is hereby defined to be an "Event of Default":

            (a) Any levy or execution upon, or judicial seizure of, any portion
      of the Collateral or any other collateral or security for the Obligation.

            (b) Any attachment or garnishment of, or the existence or filing of
      any lien or encumbrance against, any portion of the

                                       -8-


<PAGE>   9










      Collateral or any other collateral or security for the Obligation that is
      not removed and released within forty-five (45) days after its creation.

            (c) The institution of any legal action or proceedings to enforce
      any lien or encumbrance upon any portion of the Collateral or any other
      collateral or security for the Obligation, that is not dismissed within
      forty-five (45) days after its institution.

            (d) The abandonment by Debtor of all or any part of the Collateral.

            (e) The loss, theft or destruction of, or any substantial damage to,
      any portion of the Collateral or any other collateral or security for the
      Obligation, that is not adequately covered by insurance.

            (f) The occurrence of any event of default under the Note, the Loan
      Agreement or any other document or instrument executed or delivered in
      connection with the Obligation and the expiration of any applicable notice
      and cure period.

      8.2   Secured Party, so far as may be lawful, may purchase all or any part
of the Collateral offered at any public or private sale made in the enforcement
of Secured Party's rights and remedies hereunder.

      8.3   Any demand or notice of sale, disposition or other intended action
hereunder or in connection herewith, whether required by the Uniform Commercial
Code or otherwise, shall be deemed to be commercially reasonable and effective
if such demand or notice is given to Debtor at least five (5) days prior to such
sale, disposition or other intended action, in the manner provided herein for
the giving of notices.

      8.4   Debtor shall pay all costs and expenses, including without 
limitation costs of Uniform Commercial Code searches, court costs and reasonable
attorneys' fees, incurred by Secured Party in enforcing payment and performance
of the Obligation or in exercising the rights and remedies of Secured Party
hereunder. All such costs and expenses shall be secured by this Agreement and by
all deeds of trust and other lien and security documents securing the
Obligation. In the event of any court proceedings, court costs and attorneys'
fees shall be set by the court and not by jury and shall be included in any
judgment obtained by Secured Party or Debtor.

      8.5   In addition to any remedies provided herein for an Event of Default,
Secured Party shall have all the rights and remedies afforded a secured party
under the Uniform Commercial Code and all other legal and equitable remedies
allowed under applicable law. No failure on the part of Secured Party to
exercise any of its rights hereunder arising upon any Event of Default shall be

                                       -9-


<PAGE>   10










construed to prejudice its rights upon the occurrence of any other or subsequent
Event of Default. No delay on the part of Secured Party in exercising any such
rights shall be construed to preclude it from the exercise thereof at any time
while that Event of Default is continuing. Secured Party may enforce any one or
more rights or remedies hereunder successively or concurrently. By accepting
payment or performance of any of the Obligation after its due date, Secured
Party shall not thereby waive the agreement contained herein that time is of the
essence, nor shall Secured Party waive either its right to require prompt
payment or performance when due of the remainder of the Obligation or its right
to consider the failure to so pay or perform an Event of Default.

9.    MISCELLANEOUS PROVISIONS

      9.1 The acceptance of this Agreement by Secured Party shall not be
considered a waiver of or in any way to affect or impair any other security that
Secured Party may have, acquire simultaneously herewith, or hereafter acquire
for the payment or performance of the Obligation, nor shall the taking by
Secured Party at any time of any such additional security be construed as a
waiver of or in any way to affect or impair the Security Interest; Secured Party
may resort, for the payment or performance of the Obligation, to its several
securities therefor in such order and manner as it may determine.

      9.2 Without notice or demand, without affecting the obligations of Debtor
hereunder or the personal liability of any person for payment or performance of
the Obligation, and without affecting the Security Interest or the priority
thereof, Secured Party, from time to time, may: (i) extend the time for payment
of all or any part of the Obligation, accept a renewal note therefor, reduce the
payments thereon, release any person liable for all or any part thereof, or
otherwise change the terms of all or any part of the Obligation; (ii) take and
hold other security for the payment or performance of the Obligation and
enforce, exchange, substitute, subordinate, waive or release any such security;
(iii) join in any extension or subordination agreement; or (iv) release any part
of the Collateral from the Security Interest.

      9.3 Debtor waives and agrees not to assert: (i) any right to require
Secured Party to proceed against any guarantor, to proceed against or exhaust
any other security for the Obligation, to pursue any other remedy available to
Secured Party, or to pursue any remedy in any particular order or manner; (ii)
the benefits of any legal or equitable doctrine or principle of marshalling;
(iii) the benefits of any statute of limitations affecting the enforcement
hereof; (iv) demand, diligence, presentment for payment, protest and demand, and
notice of extension, dishonor, protest, demand and nonpayment, relating to the
Obligation; and (v) any benefit of, and any right to participate in, any other
security now or hereafter held by Secured Party.

      9.4 The terms herein shall have the meanings in and be construed under the
Uniform Commercial Code. This Agreement shall be governed by and construed
according to the laws of the State of Arizona. Each provision of this Agreement

                                      -10-


<PAGE>   11










shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be void or
invalid, the same shall not affect the remainder hereof which shall be effective
as though the void or invalid provision had not been contained herein.

      9.5 No modification, rescission, waiver, release or amendment of any
provision of this Agreement shall be made except by a written agreement executed
by Debtor and a duly authorized officer of Secured Party.

      9.6 This is a continuing Agreement which shall remain in full force and
effect until actual receipt by Secured Party of written notice of its revocation
as to future transactions and shall remain in full force and effect thereafter
until all of the Obligation incurred before the receipt of such notice, and all
of the Obligation incurred thereafter under commitments extended by Secured
Party before the receipt of such notice, shall have been paid and performed in
full.

      9.7 No setoff or claim that Debtor now has or may in the future have
against Secured Party shall relieve Debtor from paying or performing the
Obligation.

      9.8 Time is of the essence hereof. If more than one Debtor is named
herein, the word "Debtor" shall mean all and any one or more of them, severally
and collectively. All liability hereunder shall be joint and several. This
Agreement shall be binding upon, and shall inure to the benefit of, the parties
hereto and their heirs, personal representatives, successors and assigns. The
term "Secured Party" shall include not only the original Secured Party hereunder
but also any future owner and holder, including pledgees, of note or notes
evidencing the Obligation. The provisions hereof shall apply to the parties
according to the context thereof and without regard to the number or gender of
words or expressions used.

      9.9 All notices required or permitted to be given hereunder shall be in
writing and may be given in person or by United States mail, by delivery service
or by electronic transmission. Any notice directed to a party to this Agreement
shall become effective upon the earliest of the following: (i) actual receipt by
that party; (ii) delivery to the designated address of that party, addressed to
that party; or (iii) if given by certified or registered United States mail,
twenty-four (24) hours after deposit with the United States Postal Service,
postage prepaid, addressed to that party at its designated address. The
designated address of a party shall be the address of that party shown at the
beginning of this Agreement or such other address as that party, from time to
time, may specify by notice to the other parties.

      FOR VALUE RECEIVED, the undersigned BOWMAR INSTRUMENT CORPORATION, an
Indiana corporation (hereinafter called "Maker"), promises to pay to the order
of BANK ONE, ARIZONA, NA, a national banking association (the "Payee"; Payee and
each subsequent transferee and/or owner of this Note, whether taking by
endorsement or otherwise, are herein successively called "Holder") at Post
Office Box 71, Phoenix, Arizona 85001, Attention: Commercial Banking A593, or at
such other place as Holder may from time to time designate in writing, the
principal sum of ONE MILLION AND NO/100 DOLLARS ($1,000,000.00) or so much
thereof as Holder may advance to or for the benefit of Maker plus interest
calculated on a daily basis (based on a 360-day year) from the date hereof on
the principal balance from time to time outstanding as hereinafter provided,
principal, interest and all other sums payable hereunder to be paid in lawful
money of the United States of America as follows:

            A. Interest shall accrue on the unpaid principal balance of this
      Note at the Floating Rate, provided, that Maker may elect, upon written
      notice that is received by Holder at least ten (10) days prior to the
      Conversion Date, that interest accrue at the Conversion Rate, in which
      case, commencing on the Conversion Date, interest shall accrue at the
      Conversion Rate. During the period that interest accrues at the Floating

      effective date of, and in conformity with, changes in the Prime Rate.

            B. All accrued interest shall be due and payable on each Payment 
      Date prior to the Advance Termination Date.

            C. Commencing on the first Payment Date on or after the Advance
      Termination Date, unless and until Maker shall elect that interest accrue
      under this Note at the Conversion Rate, monthly installments of interest
      and principal shall be due and payable on each Payment Date each in a
      principal amount sufficient to amortize the principal balance outstanding
      on the Conversion Date over sixty (60) equal monthly installments, plus
      all accrued and unpaid interest.

            D. Should Maker elect that this Note bear interest at the Conversion
      Rate, equal payments of principal and interest shall be due and payable in
      consecutive monthly installments commencing on


<PAGE>   2









      the first Payment Date after the Conversion Date, and continuing on each
      Payment Date thereafter, each in an amount sufficient to fully amortize
      the principal amount of this Note outstanding on the Conversion Date, at
      the Conversion Rate, over an amortization period equal to number of months
      remaining until the Maturity Date.

            E. The entire unpaid principal balance, all accrued and unpaid
      interest, and all other amounts payable under this Note shall be due and
      payable in full on the Maturity Date.

      As used in this Note:

            "Advance Termination Date" means the date that is twelve (12) months
      after the date of this Note.

            "Business Day" means a day of the year on which banks are not
      required or authorized to close in Phoenix, Arizona.

            "Conversion Date" means the date on or after the Advance Termination
      Date selected by Maker from which interest shall accrue under this Note at
      the Conversion Rate.

            "Conversion Rate" means the rate per annum equal to the sum of (i)
      four percent (4%) per annum, and (ii) the yield to maturity of Treasury
      Obligations having a maturity date nearest to the Maturity Date determined
      two Business Days before the Conversion Date. The maturity date and yield
      of said Treasury Obligations shall be determined by Holder, in its
      absolute and sole discretion, on the basis of quotations published in The
      Wall Street Journal or other comparable sources.

            "Default Rate" means an interest rate per annum equal to four
      percent (4%) above the rate that would otherwise be payable under the
      terms of the respective Notes.

            "Floating Rate" means the rate per annum equal to the sum of (i) one
      and one half percent (1.5%) per annum, and (ii) the Prime Rate per annum
      as in effect from time to time. The Floating Rate will change on each day
      that the "Prime Rate" changes.

            "Maturity Date" means July 31, 2001.

            "Payment Date" means the first day of the first month after the

      then such Payment Date should be the next successive Business Day.

                                       -2-


<PAGE>   3









            "Prime Rate" means the interest rate per annum publicly announced by
      Bank One, Arizona, NA, a national banking association, or its successors,
      in Phoenix, Arizona as its "prime rate" as in effect from time to time.
      Maker acknowledges that the Prime Rate is not necessarily the best or
      lowest rate offered by such Bank and such Bank may lend to its customers
      at rates that are at, above or below its Prime Rate.

            "Treasury Obligations" means United States Treasury debt
      obligations.

      Maker agrees to an effective rate of interest that is the rate stated
above plus any additional rate of interest resulting from any other charges in
the nature of interest paid or to be paid by or on behalf of Maker, or any
benefit received or to be received by Holder, in connection with this Note.

      If any payment required under this Note is not paid when due, within
fifteen (15) days after the date such payment is due, then, at the option of
Holder, Maker shall pay a "late charge" equal to four percent (4%) of the amount
of that payment to compensate Holder for administrative expenses and other costs
of delinquent payments. This late charge may be assessed without notice, shall
be immediately due and payable and shall be in addition to all other rights and
remedies available to Holder.

      All payments made on this Note shall be applied, to the extent of the
amount thereof, in the order of priority to be determined by Holder in its sole
discretion: (i) to the payment of costs, fees or other charges incurred in
connection with the indebtedness evidenced hereby: (ii) to the payment of
accrued interest; and/or (iii) to the reduction of the principal balance.

      This Note is issued pursuant to that Loan Agreement (the "Loan Agreement")
of even date herewith between Maker and Payee and is secured by, among other
things, Mortgages of even date herewith, executed by Maker, as trustor, in favor
of Payee, as beneficiary, encumbering property situate in Fort Wayne, Indiana
and Acton, Massachusetts. Such Mortgages and all other documents or instruments
securing the indebtedness evidenced by this Note or executed or delivered in
connection with the indebtedness evidenced by this Note are hereinafter called
the "Security Documents."

      Time is of the essence of this Note. At the option of Holder, the entire
unpaid principal balance, all accrued and unpaid interest and all other amounts
payable hereunder shall become immediately due and payable without notice upon
the failure to pay any sum due and owing hereunder as provided herein if such
failure continues for fifteen (15) days after notice thereof to Maker or upon
the occurrence of any Event of Default, as defined in the Loan Agreement or any
of the Security Documents.

      After maturity, including maturity upon acceleration, the unpaid principal
balance, all accrued and unpaid interest and all other amounts payable hereunder

                                       -3-


<PAGE>   4









shall bear interest at the Default Rate. Maker shall pay all costs and expenses,
including reasonable attorneys' fees and court costs, incurred in the collection
or enforcement of all or any part of this Note. All such costs and expenses
shall be secured by the Mortgages and by all other Security Documents. In the
event of any court proceedings, court costs and attorneys' fees shall be set by
the court and not by jury and shall be included in any judgment obtained by
Holder or Maker.

      Maker may prepay the outstanding principal balance hereof, in whole or in
part, at any time prior to the Maturity Date. Subject to the right of Maker to
prepay this Note in full without prepayment premium in the event the RLC (as
defined in the Loan Agreement) is not renewed by Holder upon any scheduled
maturity thereunder, after the Conversion Date, with any such prepayments
(whether made voluntarily or involuntarily as a result of an acceleration of the
Maturity Date or otherwise), Maker shall also pay (a) all accrued and unpaid
interest on the principal being prepaid, (b) all other amounts then due and
payable by Maker to Holder under this Note, the Loan Agreement and the Security
Documents, and (c) a prepayment premium, if any, equal to the product of (i) the
Average Lost Monthly Interest Income and (ii) the number of months from the date
of prepayment to the Maturity Date (with any fraction of a month counted as a
month), discounted to present value at the Discount Rate over a period equal to
one-half of the number of months in (ii) above. At the option of Holder, in its
absolute and sole discretion, any prepayment shall be applied to installments
coming due hereunder in the inverse order of their due dates.

      As used in the preceding paragraph:

            "Average Lost Monthly Interest Income" means the amount determined
      by dividing (i) the product of the Average Principal and the Lost Rate, by
      (ii) 12, where:

                  "Average Principal" means the amount equal to either (i) one
            half the sum of (A) the amount of principal being prepaid and (B)
            the amount of principal that is scheduled to be due on the Maturity
            Date ("Balloon Amount"), or (ii) the amount of principal being
            prepaid, if such amount is less than the Balloon Amount; and

                  "Lost Rate" means the rate per annum equal to the percentage,
            if any, by which (i) the yield to maturity of Treasury Obligations
            having a maturity date nearest to the Maturity Date determined on
            the date hereof exceeds (ii) the yield to maturity of Treasury
            Obligations having a maturity date nearest to the Maturity Date
            determined on the date of prepayment.

                                       -4-


<PAGE>   5

            "Discount Rate" means the rate per annum equal to the yield to
      maturity of Treasury Obligations having a maturity date nearest to the
      Maturity Date determined on the date of prepayment.

The maturity date and yield to maturity of Treasury Obligations shall be
determined by Holder, in its absolute and sole discretion, on the basis of
quotations published in The Wall Street Journal or other comparable sources.

      Failure of Holder to exercise any option hereunder shall not constitute a
waiver of the right to exercise the same in the event of any subsequent default
or in the event of continuance of any existing default after demand for strict
performance hereof.

      Maker and all sureties, guarantors and/or endorsers hereof (or of any
obligation hereunder) and accommodation parties hereon (severally each
hereinafter called a "Surety") each: (a) agree that the liability under this
Note of all parties hereto is joint and several; (b) severally waive any
exemption laws and right thereunder affecting the full collection of this Note;
(c) severally waive any and all formalities in connection with this Note to the
maximum extent allowed by law, including (but not limited to) demand, diligence,
presentment for payment, protest and demand, and notice of extension, dishonor,
protest, demand and nonpayment of this Note; and (d) consent that Holder may
extend the time of payment or otherwise modify the terms of payment of any part
or the whole of the debt evidenced by this Note, at the request of any other
person liable hereon, and such consent shall not alter nor diminish the
liability of any person hereon.

      In addition, each Surety waives and agrees not to assert: (a) any right to
require Holder to proceed against Maker or any other Surety, to proceed against
or exhaust any security for the Note, to pursue any other remedy available to
Holder, or to pursue any remedy in any particular order or manner; (b) the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement hereof; (c) the benefits of any legal or equitable doctrine or
principle of marshalling; (d) notice of the existence, creation or incurring of
new or additional indebtedness of Maker to Holder; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of Sections 12-1641, et seq., of the Arizona Revised
Statutes; (f) any defense arising by reason of any disability or other defense
of Maker or by reason of the cessation from any cause whatsoever (other than
payment in full) of the liability of Maker for payment of the Note; and (g) the
benefits of any statutory provision limiting the right of Holder to recover a
deficiency judgment, or to otherwise proceed against any person or entity
obligated for payment of the Note, after any foreclosure or trustee's sale of
any security for the Note, including without limitation the benefits, if any, to
a Surety of Arizona Revised Statutes Section 33-814. Until payment in full of
the Note, no Surety shall have any right of subrogation and each hereby waives
any right to enforce any remedy which Holder now has, or may hereafter have,
against Maker or any other Surety, and waives any benefit of, and any right to
participate in, any security now or hereafter held by Holder.

                                       -5-

      Maker agrees that to the extent Maker or any Surety makes any payment to
Holder in connection with the indebtedness evidenced by this Note, and all or
any part of such payment is subsequently invalidated, declared to be fraudulent
or preferential, set aside or required to be repaid by Holder or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then the indebtedness of Maker under this Note shall continue or
shall be reinstated, as the case may be, and, to the extent of such payment or
repayment by Holder, the indebtedness evidenced by this Note or part thereof
intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

      Without limiting the right of Holder to bring any action or proceeding
against Maker or any Surety or against any property of Maker or any Surety (an
"Action") arising out of or relating to this Note or any indebtedness evidenced
hereby in the courts of other jurisdictions, Maker and each Surety hereby
irrevocably submit to the jurisdiction, process and venue of any Arizona State
or Federal court sitting in Phoenix, Arizona, and hereby irrevocably agree that
any Action may be heard and determined in such Arizona State court or in such
Federal court. Maker and all Sureties each hereby irrevocably waives, to the
fullest extent it may effectively do so, the defenses of lack of jurisdiction
over any person, inconvenient forum or improper venue, to the maintenance of any
Action in any jurisdiction.

      This Note shall be binding upon Maker and its successors and assigns and
shall inure to the benefit of Payee, and any subsequent holders of this Note,
and their successors and assigns.

      All notices required or permitted in connection with this Note shall be
given at the place and in the manner provided in the Loan Agreement for the
giving of notices.

      This Note shall be governed by and construed according to the laws of the
State of Arizona.

      IN WITNESS WHEREOF, these presents are executed as of the date first
written above.

      FOR VALUE RECEIVED, the undersigned BOWMAR INSTRUMENT CORPORATION, an
Indiana corporation (hereinafter called "Maker"), promises to pay to the order
of BANK ONE, ARIZONA, NA, a national banking association (the "Payee"; Payee and
each subsequent transferee and/or owner of this Note, whether taking by
endorsement or otherwise, are herein successively called "Holder") at Post
Office Box 71, Phoenix, Arizona 85001, Attention: Commercial Banking A593, or at
such other place as Holder may from time to time designate in writing, the
principal sum of FOUR MILLION TWO HUNDRED THOUSAND AND NO/100 DOLLARS
($4,200,000.00) or so much thereof as Holder may advance to or for the benefit
of Maker plus interest calculated on a daily basis (based on a 360-day year)
from the date hereof on the principal balance from time to time outstanding as
hereinafter provided, principal, interest and all other sums payable hereunder
to be paid in lawful money of the United States of America as follows:

            A. Interest shall accrue on the unpaid principal balance of this
      Note at the Floating Rate, provided, that Maker may elect, upon written
      notice that is received by Holder at least ten (10) days prior to the
      Conversion Date, that interest accrue at the Conversion Rate, in which
      case, commencing on the Conversion Date, interest shall accrue at the
      Conversion Rate. During the period that interest accrues at the Floating
      Rate, the interest rate on this Note shall change from time to time on the
      effective date of, and in conformity with, changes in the Prime Rate.

            B. Unless and until Maker shall elect that interest accrue under
      this Note at the Conversion Rate, monthly installments of interest and
      principal shall be due and payable on each Payment Date in the principal
      amount of $35,000.00 each, plus all accrued and unpaid interest.

            C. Should Maker elect that this Note bear interest at the Conversion
      Rate, equal payments of principal and interest shall be due and payable in
      consecutive monthly installments commencing on the first Payment Date
      after the Conversion Date, and continuing on each Payment Date thereafter,
      each in an amount sufficient to fully amortize the principal amount of
      this Note outstanding on the Conversion Date, at the Conversion Rate, over
      an amortization period equal to one hundred twenty (120) months less the
      full number of

      months that elapsed between the date of this Note and the Conversion
      Date.

            D. The entire unpaid principal balance, all accrued and unpaid
      interest, and all other amounts payable under this Note shall be due and
      payable in full on the Maturity Date.

      As used in this Note:

            "Business Day" means a day of the year on which banks are not
      required or authorized to close in Phoenix, Arizona.

            "Conversion Date" means the date selected by Maker from which

            "Conversion Rate" means the rate per annum equal to the sum of (i)
      three and three-quarters percent (3.75%) per annum, and (ii) the yield to
      maturity of Treasury Obligations having a maturity date nearest to the
      Maturity Date determined two Business Days before the Conversion Date. The
      maturity date and yield of said Treasury Obligations shall be determined
      by Holder, in its absolute and sole discretion, on the basis of quotations
      published in The Wall Street Journal or other comparable sources.

            "Default Rate" means an interest rate per annum equal to four
      percent (4%) above the rate that would otherwise be payable under the
      terms of the respective Notes.

            "Floating Rate" means the rate per annum equal to the sum of (i) one
      and one quarter percent (1.25%) per annum, and (ii) the Prime Rate per
      annum as in effect from time to time. The Floating Rate will change on
      each day that the "Prime Rate" changes.

            "Maturity Date" means July 31, 2000.

            "Payment Date" means the first day of the first month after the
      initial advance of proceeds under this Note and the first day of each
      month thereafter, provided that if any such day is not a Business Day,
      then such Payment Date should be the next successive Business Day.

            "Prime Rate" means the interest rate per annum publicly announced by
      Bank One, Arizona, NA, a national banking association, or its successors,
      in Phoenix, Arizona as its "prime rate" as in effect from time to time.
      Maker acknowledges that the Prime Rate is not necessarily the best or
      lowest rate offered by such Bank and such Bank may lend to its customers
      at rates that are at, above or below its Prime Rate.

            "Treasury Obligations" means United States Treasury debt
      obligations.

      Maker agrees to an effective rate of interest that is the rate stated
above plus any additional rate of interest resulting from any other charges in
the nature of interest paid or to be paid by or on behalf of Maker, or any
benefit received or to be received by Holder, in connection with this Note.

      If any payment required under this Note is not paid when due, within
fifteen (15) days after the date such payment is due, then, at the option of
Holder, Maker shall pay a "late charge" equal to four percent (4%) of the amount
of that payment to compensate Holder for administrative expenses and other costs
of delinquent payments. This late charge may be assessed without notice, shall
be immediately due and payable and shall be in addition to all other rights and
remedies available to Holder.

      All payments made on this Note shall be applied, to the extent of the
amount thereof, in the order of priority to be determined by Holder in its sole
discretion: (i) to the payment of costs, fees or other charges incurred in
connection with the indebtedness evidenced hereby: (ii) to the payment of
accrued interest; and/or (iii) to the reduction of the principal balance.

      This Note is issued pursuant to that Loan Agreement (the "Loan Agreement")
of even date herewith between Maker and Payee and is secured by, among other
things, Mortgages of even date herewith, executed by Maker, as trustor, in favor
of Payee, as beneficiary, encumbering property situate in Fort Wayne, Indiana
and Acton, Massachusetts. Such Mortgages and all other documents or instruments
securing the indebtedness evidenced by this Note or executed or delivered in
connection with the indebtedness evidenced by this Note are hereinafter called
the "Security Documents."

      Time is of the essence of this Note. At the option of Holder, the entire
unpaid principal balance, all accrued and unpaid interest and all other amounts
payable hereunder shall become immediately due and payable without notice upon
the failure to pay any sum due and owing hereunder as provided herein if such
failure continues for fifteen (15) days after notice thereof to Maker or upon
the occurrence of any Event of Default, as defined in the Loan Agreement or any
of the Security Documents.

      After maturity, including maturity upon acceleration, the unpaid principal
balance, all accrued and unpaid interest and all other amounts payable hereunder
shall bear interest at the Default Rate. Maker shall pay all costs and expenses,
including reasonable attorneys' fees and court costs, incurred in the collection
or enforcement of all or any part of this Note. All such costs and expenses
shall be secured by the Mortgages and by all other Security Documents. In the
event of any court proceedings, court costs and attorneys' fees shall be set by
the court and not by jury and shall be included in any judgment obtained by
Holder or Maker.

                                       -3-

      Maker may prepay the outstanding principal balance hereof, in whole or in
part, at any time prior to the Maturity Date. Subject to the right of Maker to
prepay this Note in full without prepayment premium in the event the RLC (as
defined in the Loan Agreement) is not renewed by Holder upon any scheduled
maturity thereunder, after the Conversion Date, with any such prepayments
(whether made voluntarily or involuntarily as a result of an acceleration of the
Maturity Date or otherwise), Maker shall also pay (a) all accrued and unpaid
interest on the principal being prepaid, (b) all other amounts then due and
payable by Maker to Holder under this Note, the Loan Agreement and the Security
Documents, and (c) a prepayment premium, if any, equal to the product of (i) the
Average Lost Monthly Interest Income and (ii) the number of months from the date
of prepayment to the Maturity Date (with any fraction of a month counted as a
month), discounted to present value at the Discount Rate over a period equal to
one-half of the number of months in (ii) above. At the option of Holder, in its
absolute and sole discretion, any prepayment shall be applied to installments
coming due hereunder in the inverse order of their due dates.

      As used in the preceding paragraph:

            "Average Lost Monthly Interest Income" means the amount determined
      by dividing (i) the product of the Average Principal and the Lost Rate, by
      (ii) 12, where:

                  "Average Principal" means the amount equal to either (i) one
            half the sum of (A) the amount of principal being prepaid and (B)
            the amount of principal that is scheduled to be due on the Maturity
            Date ("Balloon Amount"), or (ii) the amount of principal being
            prepaid, if such amount is less than the Balloon Amount; and

                  "Lost Rate" means the rate per annum equal to the percentage,
            if any, by which (i) the yield to maturity of Treasury Obligations
            having a maturity date nearest to the Maturity Date determined on
            the date hereof exceeds (ii) the yield to maturity of Treasury
            Obligations having a maturity date nearest to the Maturity Date
            determined on the date of prepayment.

            "Discount Rate" means the rate per annum equal to the yield to
      maturity of Treasury Obligations having a maturity date nearest to the
      Maturity Date determined on the date of prepayment.

The maturity date and yield to maturity of Treasury Obligations shall be
determined by Holder, in its absolute and sole discretion, on the basis of
quotations published in The Wall Street Journal or other comparable sources.

      Failure of Holder to exercise any option hereunder shall not constitute a
waiver of the right to exercise the same in the event of any subsequent default

                                       -4-

or in the event of continuance of any existing default after demand for strict
performance hereof.

      Maker and all sureties, guarantors and/or endorsers hereof (or of any
obligation hereunder) and accommodation parties hereon (severally each
hereinafter called a "Surety") each: (a) agree that the liability under this
Note of all parties hereto is joint and several; (b) severally waive any
exemption laws and right thereunder affecting the full collection of this Note;
(c) severally waive any and all formalities in connection with this Note to the
maximum extent allowed by law, including (but not limited to) demand, diligence,
presentment for payment, protest and demand, and notice of extension, dishonor,
protest, demand and nonpayment of this Note; and (d) consent that Holder may
extend the time of payment or otherwise modify the terms of payment of any part
or the whole of the debt evidenced by this Note, at the request of any other
person liable hereon, and such consent shall not alter nor diminish the
liability of any person hereon.

      In addition, each Surety waives and agrees not to assert: (a) any right to
require Holder to proceed against Maker or any other Surety, to proceed against
or exhaust any security for the Note, to pursue any other remedy available to
Holder, or to pursue any remedy in any particular order or manner; (b) the
benefit of any statute of limitations affecting its liability hereunder or the
enforcement hereof; (c) the benefits of any legal or equitable doctrine or
principle of marshalling; (d) notice of the existence, creation or incurring of
new or additional indebtedness of Maker to Holder; (e) the benefits of any
statutory provision limiting the liability of a surety, including without
limitation the provisions of Sections 12-1641, et seq., of the Arizona Revised
Statutes; (f) any defense arising by reason of any disability or other defense
of Maker or by reason of the cessation from any cause whatsoever (other than
payment in full) of the liability of Maker for payment of the Note; and (g) the
benefits of any statutory provision limiting the right of Holder to recover a
deficiency judgment, or to otherwise proceed against any person or entity
obligated for payment of the Note, after any foreclosure or trustee's sale of
any security for the Note, including without limitation the benefits, if any, to
a Surety of Arizona Revised Statutes Section 33-814. Until payment in full of
the Note, no Surety shall have any right of subrogation and each hereby waives
any right to enforce any remedy which Holder now has, or may hereafter have,
against Maker or any other Surety, and waives any benefit of, and any right to
participate in, any security now or hereafter held by Holder.

      Maker agrees that to the extent Maker or any Surety makes any payment to
Holder in connection with the indebtedness evidenced by this Note, and all or
any part of such payment is subsequently invalidated, declared to be fraudulent
or preferential, set aside or required to be repaid by Holder or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then the indebtedness of Maker under this Note shall continue or
shall be reinstated, as the case may be, and, to the extent of such payment or
repayment by Holder, the indebtedness evidenced by this Note or part thereof

                                       -5-

intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

      Without limiting the right of Holder to bring any action or proceeding
against Maker or any Surety or against any property of Maker or any Surety (an
"Action") arising out of or relating to this Note or any indebtedness evidenced
hereby in the courts of other jurisdictions, Maker and each Surety hereby
irrevocably submit to the jurisdiction, process and venue of any Arizona State
or Federal court sitting in Phoenix, Arizona, and hereby irrevocably agree that
any Action may be heard and determined in such Arizona State court or in such
Federal court. Maker and all Sureties each hereby irrevocably waives, to the
fullest extent it may effectively do so, the defenses of lack of jurisdiction
over any person, inconvenient forum or improper venue, to the maintenance of any
Action in any jurisdiction.

      This Note shall be binding upon Maker and its successors and assigns and
shall inure to the benefit of Payee, and any subsequent holders of this Note,
and their successors and assigns.

      All notices required or permitted in connection with this Note shall be
given at the place and in the manner provided in the Loan Agreement for the
giving of notices.

      This Note shall be governed by and construed according to the laws of the
State of Arizona.

      IN WITNESS WHEREOF, these presents are executed as of the date first
written above.

accrued interest; and/or (iii) to the reduction of the principal balance.

      This Note is issued pursuant to that Loan Agreement (the "Loan Agreement")

or in the event of continuance of any existing default after demand for strict
performance hereof.

Statutes; (f) any defense arising by reason of any disability or other defense
of Maker or by reason of the cessation from any cause whatsoever (other than
payment in full) of the liability of Maker for payment of the Note; and (g) the
benefits of any statutory provision limiting the right of Holder to recover a
deficiency judgment, or to otherwise proceed against any person or entity
obligated for payment of the Note, after any foreclosure or trustee's sale of
any security for the Note, including without limitation the benefits, if any, to
a Surety of Arizona Revised Statutes Section 33-814. Until payment in full of
the Note, no Surety shall have any right of subrogation and each hereby waives
any right to enforce any remedy which Holder now has, or may hereafter have,
against Maker or any other Surety, and waives any benefit of, and any right to
participate in, any security now or hereafter held by Holder.

      Maker agrees that to the extent Maker or any Surety makes any payment to
Holder in connection with the indebtedness evidenced by this Note, and all or
any part of such payment is subsequently invalidated, declared to be fraudulent
or preferential, set aside or required to be repaid by Holder or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise (any such payment is hereinafter referred to as a "Preferential
Payment"), then the indebtedness of Maker under this Note shall continue or
shall be reinstated, as the case may be, and, to the extent of such payment or
repayment by Holder, the indebtedness evidenced by this Note or part thereof
intended to be satisfied by such Preferential Payment shall be revived and
continued in full force and effect as if said Preferential Payment had not been
made.

      Without limiting the right of Holder to bring any action or proceeding
against Maker or any Surety or against any property of Maker or any Surety (an
"Action") arising out of or relating to this Note or any indebtedness evidenced
hereby in the courts of other jurisdictions, Maker and each Surety hereby
irrevocably submit to the jurisdiction, process and venue of any Arizona State
or Federal court sitting in Phoenix, Arizona, and hereby irrevocably agree that
any Action may be heard and determined in such Arizona State court or in such
Federal court. Maker and all Sureties each hereby irrevocably waives, to the
fullest extent it may effectively do so, the defenses of lack of jurisdiction
over any person, inconvenient forum or improper venue, to the maintenance of any
Action in any jurisdiction.

      This Note shall be binding upon Maker and its successors and assigns and
shall inure to the benefit of Payee, and any subsequent holders of this Note,
and their successors and assigns.

      All notices required or permitted in connection with this Note shall be
given at the place and in the manner provided in the Loan Agreement for the
giving of notices.

                                    (Indiana)

               FOR PURPOSES OF THE SECURITY AGREEMENT CONTAINED
                IN THIS INSTRUMENT THE "SECURED PARTY" AND THE
           "DEBTOR" AND THEIR RESPECTIVE ADDRESSES ARE AS FOLLOWS:

SECURED PARTY:    BANK ONE, ARIZONA, NA, a national banking association
                  POST OFFICE BOX 71
                  PHOENIX, ARIZONA  85001
                  ATTENTION:  COMMERCIAL BANKING A593

DEBTOR:           BOWMAR INSTRUMENT CORPORATION, an Indiana corporation
                  5080 NORTH 40TH STREET, SUITE 475
                  PHOENIX, ARIZONA  85018
                  ATTENTION:  JOSEPH G. WARREN, JR.

      THIS INSTRUMENT WHEN RECORDED SHALL CONSTITUTE A "FIXTURE FILING" FOR
PURPOSES OF THE UNIFORM COMMERCIAL CODE. THE ADDRESS OF THE SECURED PARTY SHOWN
ABOVE IS THE ADDRESS AT WHICH INFORMATION CONCERNING THE SECURED PARTY'S
SECURITY INTEREST MAY BE OBTAINED.

      BOWMAR INSTRUMENT CORPORATION, an Indiana corporation (the "Mortgagor"),
MORTGAGES AND WARRANTS to BANK ONE, ARIZONA, NA, a national banking association
with its principal office in Phoenix, Arizona (the "Bank") and the Mortgagor
GRANTS A SECURITY INTEREST to the Bank in the following property, to-wit:

      all that real estate located in Allen County, Indiana, described in
      Schedule "A" which is attached to this Mortgage, Security Agreement,
      Assignment of Rents and Fixture Filing (this "Mortgage") and incorporated
      herein by this reference (the "Real Estate"); and

      any items of furniture, machinery, equipment or other tangible personal
      property which are now or hereafter become attached to the Real Estate or
      any improvement thereon so as to constitute a fixture, whether now owned
      or hereinafter acquired (the "Personal Property").

      TOGETHER WITH all present and future improvements, rights, privileges,
interests, easements, hereditaments, and appurtenances thereunto belonging or in
any manner pertaining thereto, and the proceeds therefrom (all of such Real
Estate, Personal Property and other rights being hereafter referred to as the
"Mortgaged Premises").

      This Mortgage is given to secure all of the Mortgagor's Obligations to the
Bank. The term "Obligations" as used in this Mortgage means all obligations of
the Mortgagor in favor of the Bank of every type and description, direct or


<PAGE>   2








indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, including but not limited to all Obligations of the Mortgagor
in favor of the Bank arising under a Loan Agreement between the Mortgagor and
the Bank dated the date of this Mortgage (the "Loan Agreement"), which
Obligations include the obligation of the Mortgagor to repay all advances made
by the Bank to the Mortgagor under a revolving line of credit in the principal
amount of $4,000,000.00, to repay a term loan in the principal amount of
$4,200,000.00, and to repay all advances made by the Bank to Mortgagor under a
non-revolving acquisition line of credit in the principal sum of $1,000,000.00.
The final maturity date of the revolving line of credit is July 31, 1997, the
final maturity date of the term loan is July 31, 2000, and the final maturity
date of the non-revolving acquisition line of credit is July 31, 2001. All of
the Obligations, including those arising under the Loan Agreement, are secured
as they now exist and as they may be increased or otherwise changed by any
amendment to any instrument or agreement which now or hereafter evidences,
secures or expresses terms applicable to any of the Obligations, including
amendments to the Loan Agreement and any "Security Documents" as that term is
defined in the Loan Agreement.

      As additional security for the Obligations, the Mortgagor assigns to the
Bank the rents, issues and profits of the Mortgaged Premises, including any
rents and all other amounts (collectively "Lease Payments") which are due or
shall become due to the Mortgagor under the terms of any present or future lease
(a "Lease"), oral or written, of all or any portion of the Mortgaged Premises
(all such rents, issues, profits and Lease Payments are hereafter collectively
referred to as the "Rents"). This Assignment of Rents is an absolute assignment,
and is intended to vest in the Bank the right to collect all Rents subject only
to the conditional license to collect Rents granted by the Bank to the Mortgagor
under the terms of numbered Paragraph 7 of this Mortgage.

      The Mortgagor further covenants and agrees as follows:

      1. The Mortgagor shall pay and perform all of the Obligations promptly
when payment or performance is due, with reasonable attorneys' fees and costs of
collection, and without relief from valuation and appraisement laws.

      2. The Mortgagor shall keep the Mortgaged Premises in good repair and
shall not commit or permit waste thereon or do or permit to be done anything
that may impair the value of the Mortgaged Premises. The Mortgagor shall
promptly restore any part of the Mortgaged Premises which may be damaged or
destroyed, in a good and workmanlike manner and in conformity with the Americans
With Disabilities Act of 1990 and corresponding rules and regulations (the
"ADA") and with plans and specifications approved by Bank. The Mortgagor shall
pay when due all taxes and assessments levied or assessed against the Mortgaged
Premises or any part thereof.

      3. The Mortgagor shall comply with all statutes, ordinances, rules,
regulations, orders, and directions of any legislative, executive,
administrative, or judicial body or official applicable to the Mortgaged
Premises, or any part thereof, or to the Mortgagor, or to the operation of any
business of Mortgagor which directly affects the Mortgaged Premises; provided,
however, that the Mortgagor may contest any of the matters referred to in this

                                       -2-


<PAGE>   3








paragraph as provided in the Loan Agreement or otherwise in any reasonable
manner which in the judgment of the Bank will not adversely affect the rights of
the Bank, its successors or assigns.

      4. The Mortgagor will procure and maintain in effect at all times
insurance written by insurance companies acceptable to the Bank which insures
against loss or destruction of the Mortgaged Premises by fire, wind storm,
lightning, vandalism and malicious mischief and such other perils as are
generally covered by "extended coverage" insurance for the full replacement
value of the Mortgaged Premises. All policies providing such insurance shall
provide that any loss thereunder shall be payable to the Bank under a standard
form of secured lender's loss payable endorsement. The Mortgagor shall also
procure business interruption insurance in such amounts as the Bank may
reasonably require. The Mortgagor authorizes the Bank to endorse on Mortgagor's
behalf and to negotiate drafts representing proceeds of such insurance, provided
that the Bank shall remit to the Mortgagor such surplus, if any, as remains
after the proceeds have been applied at the Bank's option: (a) to the
satisfaction of the Obligations, whether or not then due and payable, or to the
establishment of a cash collateral account securing the Obligations, or (b) to
the restoration of the Mortgaged Premises. Certificates evidencing the existence
of all of the insurance required under the terms of this Mortgage shall be
furnished to the Bank and the original policies providing such insurance shall
be delivered to the Bank at the Bank's request. If the insurance proceeds are to
be used for the restoration and repair of the Mortgaged Premises, they shall be
held by Bank in an interest bearing account selected by Bank in its sole and
absolute discretion (the "Restoration Account"). Mortgagor, at its expense,
shall promptly prepare and submit to Bank all plans and specifications necessary
for the restoration and repair of the damaged Mortgaged Premises, together with
evidence acceptable to Bank setting forth the total expenditure needed for the
restoration and repair based upon a fixed price contract with a reputable
builder and covered by performance and labor and material payment bonds. The
plans and specifications and all other aspects of the proposed restoration and
repair shall be subject to Bank's approval. In the event the insurance proceeds
held in the Restoration Account are insufficient to complete the restoration and
repair, Mortgagor shall deposit in the Restoration Account an amount equal to
the difference between the amount then held in the Restoration Account and the
total contract price for the restoration and repair. Mortgagor may commence
restoration and repair of the damaged Mortgaged Premises only when authorized in
writing by Bank to do so and thereafter shall proceed diligently with the
restoration and repair until completed. Disbursements shall be made from the
Restoration Account for the restoration and repair in accordance with a
disbursement schedule, and subject to other terms and conditions, acceptable to
Bank. Disbursements from the Restoration Account shall be charged first against
funds deposited by Mortgagor and, after such funds are exhausted, against the
insurance proceeds deposited therein. In the event the amounts held in the
Restoration Account exceed the cost of the restoration and repair of the damaged
Mortgaged Premises, the excess funds shall be disbursed to Mortgagor to the
extent of any amounts deposited therein by Mortgagor. Any funds remaining after
such disbursement, at Bank's option, may be applied by Bank to the payment of
the Obligation, whether or not then due, or may be disbursed to Mortgagor. All
funds held in the Restoration Account are hereby assigned to Bank as further
security for the Obligation.

                                       -3-


<PAGE>   4








Bank, at any time, may apply all or any part of the funds held in the
Restoration Account to the curing of any Default.

      5. Upon demand and failure of the Mortgagor so to do, the Bank may, in its
discretion upon thirty (30) days notice to Mortgagor (unless Mortgagor
determines an emergency exists in which case no notice shall be required),
advance and pay all sums necessary to protect and preserve the Mortgaged
Premises, and all sums so advanced and paid by the Bank shall become a part of
the indebtedness secured hereby, shall bear interest from date of payment at a
rate equal to the Prime Rate plus five and one half percent (5.5%) per annum,
and shall be payable to the Bank upon demand. Such sums shall include, but not
by way of limitation: (a) taxes, assessments and other charges which may be or
become senior to this Mortgage as liens on the Mortgaged Premises, or any part
thereof; (b) the cost of any title insurance, surveys, or other evidence which
in the discretion of the Bank may be required in order to evidence, insure or
preserve the lien of this Mortgage; (c) all costs, expenses, and reasonable
attorneys' fees incurred by the Bank in respect of any and all legal and
equitable actions which relate to this Mortgage or to the Mortgaged Premises,
and (d) the cost of any repairs respecting the Mortgaged Premises which are
reasonably deemed necessary by the Bank. As used in this Mortgage, the term
"Prime Rate" means a variable per annum rate of interest equal at all times to
the rate of interest established and quoted by the Bank as its Prime Rate, such
rate to change contemporaneously with each change in such established and quoted
rate; provided that it is understood the Prime Rate shall not necessarily be
representative of the rate of interest actually charged by the Bank on any loan
or class of loans. The Bank shall be subrogated to the rights of the holder of
each lien or claim paid with moneys secured hereby. Upon written request by
Bank, Mortgagor shall appear in and prosecute or defend any action or proceeding
that may affect the lien or the priority of the lien of this Mortgage or the
rights of Bank hereunder and shall pay all costs, expenses (including the cost
of searching title) and attorneys' fees incurred in such action or proceeding.
Bank may appear in and defend any action or proceeding purporting to affect the
lien or the priority of the lien of this Mortgage or the rights of Bank.

      6. If all or any part of the Mortgaged Premises is damaged, taken, or
acquired, either temporarily or permanently, in any condemnation proceeding, or
by exercise of the right of eminent domain, or by the alteration of the grade of
any street affecting the Mortgaged Premises, the amount of any award or other
payment for such taking or damages made in consideration thereof, to the extent
of the full amount of the then remaining unpaid Obligations, is hereby assigned
to the Bank, which is empowered to collect and receive the same and to give
proper receipts therefor in the name of the Mortgagor, and all such sums shall
be paid forthwith directly to the Bank. Any award or payment so received by the
Bank may, at the option of the Bank: (a) be applied to the satisfaction of the
Obligations, whether or not then due and payable, or to the establishment of a
cash collateral account for the Obligations, or (b) be released, in whole or in
part, to the Mortgagor for the purpose of altering, restoring, or rebuilding any
part of the Mortgaged Premises which may have been altered, damaged or destroyed
as a result of such taking, alteration, or proceeding.

      7. At any time a Default (as hereafter defined) has occurred and is
continuing, the Bank may enter upon and take possession of the Real Estate or 
any

                                       -4-


<PAGE>   5








part thereof, and at any such time, or if the Bank in the reasonable exercise of
its discretion determines that payment or performance of any of the Obligations
is insecure, the Bank may demand, sue for, receive and give receipts, releases
and satisfactions for all Rents. At any time that the Bank has not exercised its
right to take possession of the Real Estate and there is not in effect any
demand by the Bank for the direct payment of Lease Payments to the Bank given
pursuant to the immediately preceding sentence, the Mortgagor may collect Lease
Payments provided that no Rents shall be collected by the Mortgagor more than
thirty (30) days in advance of the period of occupancy to which they relate.
Lease Payments collected by the Mortgagor pursuant to the license granted in the
immediately preceding sentence shall be held by the Mortgagor as trustee for the
benefit of the Bank and shall be applied to the satisfaction of Obligations to
the extent that any are then due and payable. Any balance remaining after
satisfaction of all Obligations which are then due and payable may be used by
the Mortgagor for any proper purpose. Any demand by the Bank upon any tenant of
the Mortgaged Premises accompanied by a copy of this Mortgage shall be
sufficient authority for such tenant thereafter to make all Lease Payments
directly to the Bank and any such tenant shall have no obligation or authority
to inquire into the propriety of any such demand. Upon making Lease Payments to
the Bank pursuant to the Bank's demand, any tenant of the Mortgaged Premises
shall be as fully discharged of its obligations under any Lease to the extent of
such payments as if such payments had been made directly to the Mortgagor. If at
any time Lease Payments are required to be made directly to the Bank under the
terms of this paragraph and notwithstanding such requirement such payments are
made to the Mortgagor, the Mortgagor will receive such payments in trust for the
Bank and will forward them immediately to the Bank in the form in which
received, adding only such endorsements or assignments as may be necessary to
perfect the Bank's title thereto. Any amounts collected by the Bank pursuant to
the assignment of rents contained in this Mortgage shall be applied by the Bank
to the payment of such of the Obligations as are then due and payable as the
Bank in its sole discretion shall determine. If no Obligations are then due and
payable, such amounts may be held by the Bank as cash collateral for the
Obligations, without liability for interest thereon, provided that the Bank
will, at the direction of the Mortgagor, invest such amounts for the account and
at the risk of the Mortgagor in U.S. Treasury Bills with less than 60 days
remaining to maturity or in similar essentially risk-free, cash equivalent
investments as the Mortgagor may reasonably direct and any earnings derived from
such investments will become a part of the cash collateral account. Any portion
or all of the cash collateral account which is not applied to Obligations
pursuant to the terms of this paragraph may at the discretion of the Bank be
released to the Mortgagor. The authority given to collect Rents conferred upon
the Bank under the terms of this Mortgage is irrevocable.

      8. The Mortgagor grants to the Bank as secured party a security interest
in the Personal Property in accordance with the provisions of the Uniform
Commercial Code as enacted in Indiana. The Mortgagor authorizes the Bank at the
expense of the Mortgagor to execute on its behalf and file any other financing
statements deemed necessary by the Bank to perfect its security interest in the
Personal Property and to file such financing statements in those public offices
deemed necessary by the Bank. Such financing statements may be signed by the
Bank alone. In addition, the Mortgagor shall execute and deliver any financing

                                       -5-


<PAGE>   6








statement or other document that the Bank may request to perfect or to further
evidence the security interest created by this Mortgage.

      9.    If, after the execution of this Mortgage, applicable law requires 
the taxation of this Mortgage or any Obligation secured by this Mortgage, the
Mortgagor, upon demand by the Bank, shall pay such taxes or reimburse the Bank
therefor unless it is unlawful to require the Mortgagor to do so.
Notwithstanding the foregoing, the Mortgagor shall not be obligated to pay any
portion of any of the Bank's federal or state income taxes.

            (e) Release. "Release" means the spilling, leaking, disposing,

related to (a) any actual, alleged or threatened Release of any Hazardous
Substance on, in or under the Real Estate, (b) any related injury to human
health or safety (including wrongful death) or any actual or alleged injury to

Mortgagor's storage, generation, transportation, handling or use, if any, of
Hazardous Substances on or from the Real Estate is currently, and will remain at
all times, in compliance with all applicable Environmental Laws. If any Clean-up
is required with respect to the Real Estate, the Mortgagor shall expeditiously
complete such Clean-up at the Mortgagor's expense and without the necessity of
demand by the Bank. If the Mortgagor should fail to initiate and diligently
pursue any Clean-up or should otherwise fail to perform any obligation under the
terms of this paragraph, the Bank may, at its sole discretion and without any
obligation to complete any Clean-up which it may cause to be commenced, cause
the Clean-up or partial Clean-up of the Real Estate and pay on behalf of the
Mortgagor any costs, fines or penalties imposed on the Mortgagor pursuant to any
Environmental Laws or make

                                       -7-


<PAGE>   8








any other payment or perform any other action which will prevent a lien in favor
of any federal, state or local government authority or any other person from
attaching to the Real Property pursuant to the provisions of any Environmental
Law, and all costs and expenses of the Bank incurred in pursuing any of the
remedies provided in this paragraph shall be added to the obligations secured by
this Mortgage, which costs and expenses shall become due and payable without
notice as incurred by the Bank, together with interest thereon at the Prime Rate
plus five and one half percent (5.5%) per annum until paid.

      11. Without obtaining the prior written consent of Bank, Mortgagor shall
not sell, transfer, convey, assign or otherwise dispose of, or further encumber,
all or any part of the Mortgaged Premises or any interest therein, voluntarily
or involuntarily, by operation of law or otherwise. Upon the occurrence of any
such transaction with Bank's consent, or without Bank's consent if Bank elects
not to exercise its rights and remedies for an Event of Default, Bank (i) may
increase the interest rate on all or any part of the Obligations to its then
current market rate for similar indebtedness; (ii) may charge a loan fee and a
processing fee in connection with the change; and (iii) shall not be obligated
to release Mortgagor from any liability hereunder or for the Obligations except
to the extent required by law. Consent to any such transaction shall not be
deemed to be consent or a waiver of the requirement of consent to any other such
transaction.

      12.   The occurrence of any of the following events shall be deemed a
"Default" under this Mortgage:

            (a) an "Event of Default" as defined in the Loan Agreement shall
      have occurred and be continuing or the Mortgagor shall otherwise fail to
      pay or perform any of the Obligations promptly when such payment or
      performance is due or within such grace period as may be applicable;

            (b) the Mortgagor shall otherwise fail to observe and perform the
      terms and conditions of this Mortgage and such failure continues
      unremedied for a period of thirty (30) days after notice thereof to
      Mortgagor;

            (c) the Mortgagor shall abandon the Mortgaged Premises;

            (d) Any levy or execution upon, or judicial seizure of, any portion
      of the Mortgaged Premises;

            (e) Any attachment or garnishment of, or the existence or filing of
      any lien or encumbrance other than as consented to by Bank against, any
      portion of the Mortgaged Premises, that is not removed or released within
      forty-five (45) days after its creation;

            (f) The institution of any legal action or proceedings to enforce
      any lien or encumbrance upon any portion of the Mortgaged Premises, that
      is not dismissed within forty-five (45) days after its institution;

                                       -8-


<PAGE>   9








            (g) The existence of any encroachment upon the Mortgaged Premises
      that has occurred without the approval of Bank that is not removed or
      corrected within thirty (30) days after its creation; or

            (h) The demolition or destruction of, or any substantial damage to,
      any portion of the Mortgaged Premises that is not adequately covered by
      insurance.

      13.   Upon the occurrence and continuance of a Default, all indebtedness
secured hereby shall, at the option of the Bank, become immediately due and
payable and this Mortgage may be foreclosed accordingly. Upon the occurrence and
continuance of a Default, the Bank shall be entitled to the appointment of a
receiver for the Mortgaged Premises to collect the rents and profits and to
maintain the Mortgaged Premises without regard to the adequacy of any security
for the Obligations or the solvency of Mortgagor or any other person or entity.
The Bank shall have the option of proceeding as to both the Real Estate and the
Personal Property in accordance with its rights and remedies in respect of the
Real Estate, in which event the default provisions of the Uniform Commercial
Code shall not apply. If the Bank elects to proceed with respect to the Personal
Property separately from the Real Estate, the requirement of the Uniform
Commercial Code as to reasonable notice of any proposed sale or disposition of
the Personal Property shall be met if such notice is delivered or mailed to the
Mortgagor at its address stated above at least five (5) days prior to such sale
or disposition. In any action to foreclose this Mortgage, the Bank shall be
entitled to recover, in addition to all reasonable attorney and related
paraprofessional expenses incurred in connection therewith, all other reasonable
costs and expenses associated with foreclosure including, without limitation,
all expenses incurred for title searches, abstracts of title, title insurance,
appraisals, surveys and environmental assessments reasonably deemed necessary by
the Bank, all of which costs and expenses shall be additional amounts secured by
this Mortgage. As used in the preceding sentence, the term "environmental
assessments" means inspections and reports of environmental engineers or firms
of environmental engineers or other appropriate experts, and associated
samplings and testings of soil or groundwater, the purpose of which is to
determine whether there is any Contamination associated with the Real Estate and
if so, the extent thereof, and to estimate of the cost of Clean-up of any
Contamination, and to determine whether there are any underground storage tanks
or any asbestos in, on, or under the Real Estate and if so, whether there are
any violations of Environmental Laws in connection therewith. As used in this
paragraph, the terms "Contamination," "Clean-up" and "Environmental Laws" are
used as defined in numbered Paragraph 10.

      14.   All rights, powers and remedies granted Bank herein, or otherwise
available to Bank, are for the sole benefit and protection of Bank, and Bank may
exercise any such right, power or remedy at its option and in its sole and
absolute discretion without any obligation to do so. In addition, if, under the
terms hereof, Bank is given two or more alternative courses of action, Bank may
elect any alternative or combination of alternatives, at its option and in its
sole and absolute discretion. All monies advanced by Bank under the terms hereof
and all amounts paid, suffered or incurred by Bank in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by this Mortgage, shall bear interest at a rate

                                       -9-


<PAGE>   10








equal to the Prime Rate plus five and one half percent (5.5%) per annum until
paid, and shall be due and payable by Mortgagor to Bank immediately without
demand.

      15. In order to insure the payment of taxes and assessments that are now,
or hereafter may be, a lien upon the Mortgaged Premises, and to insure the
payment of all premiums on policies of insurance required herein, Mortgagor, if
required by Bank after the occurrence of a Default, shall pay to Bank each
month, in addition to any other payments required hereunder, an amount equal to
the taxes and special assessments levied or to be levied against the Mortgaged
Premises and the premium or premiums that will become due and payable to
maintain the insurance on the Mortgaged Premises, all as reasonably estimated by
Bank (giving due consideration to the previous year's taxes, assessments and
premiums) less all deposits therefore already made, divided by the number of
months remaining before one month prior to the date when the taxes, assessments
and premiums become delinquent. If amounts paid to Bank under the terms of this
paragraph are insufficient to pay all taxes, assessments and premiums as they
become due, Mortgagor shall pay to Bank upon demand all additional sums
necessary to fully pay and discharge these items. All moneys paid to Bank under
the terms of this paragraph may be either held by Bank to pay the taxes,
assessments and premiums before the same become delinquent or applied to the
Obligation upon payment by Bank from its own funds of the taxes, assessments and
premiums. To the extent provision is not made for payment pursuant to this
paragraph, Mortgagor shall remain obligated to pay all taxes, assessments and
premiums as they become due and payable. Deposits made under this paragraph may
be commingled with Bank's general funds; Bank shall have no liability to
Mortgagor for interest on any deposits.

      16. The Bank, at its option and on such terms as it may desire, may extend
the time of payment or performance of any part or all of the Obligations or
release any part of the Mortgaged Premises from the lien of this Mortgage
without impairing the lien of this Mortgage except as to the portion of the
Mortgaged Premises expressly released and without releasing the Mortgagor or any
guarantors or sureties of or from any of the obligations. No delay by the Bank
in the exercise of any of its rights under this Mortgage shall preclude the
subsequent exercise thereof so long as any Default continues uncured, and no
waiver by the Bank of any Default of the Mortgagor shall operate as a waiver of
subsequent or other Defaults. The making of any payment by the Bank for any of
the purposes herein permitted shall not constitute a waiver of any breach of the
Mortgagor's covenant to perform such act. Notice by the Bank of its intention to
exercise any right or option under this Mortgage is expressly waived by the
Mortgagor, and any one or more of the Bank's rights or remedies under this
Mortgage may be enforced successively or concurrently. Mortgagor waives and
agrees not to assert: (i) any right to require Bank to proceed against any
guarantor, to proceed against or exhaust any other security for the Obligations,
to pursue any other remedy available to Bank, or to pursue any remedy in any
particular order or manner; (ii) the benefits of any legal or equitable doctrine
or principle of marshalling; (iii) the benefits of any statute of limitations
affecting the enforcement hereof; (iv) demand, diligence, presentment for
payment, protest and demand, and notice of extension, dishonor, protest, demand
and nonpayment, relating to the Obligations; and (v) any benefit of, and any

                                      -10-


<PAGE>   11








right to participate in, any other security now or hereafter held by Bank.  Time
is of the essence of this Mortgage.

      17. Bank shall have the right to inspect the Mortgaged Premises at all
reasonable times.

      18. All obligations of the Mortgagor under this Mortgage shall extend to
and be binding upon the successors and assigns of the Mortgagor, and shall inure
to the benefit of the Bank and its successors and assigns.

      19. This Mortgage secures indebtedness incurred for a business purpose.

      20. The Obligations and the agreements of any person or entity to pay or
perform the Obligations shall be governed by and construed according to the laws
of the State of Arizona, provided, that this Mortgage shall be governed by and
construed according to the substantive laws of the State of Indiana,
notwithstanding the fact that Indiana conflicts of law rules might otherwise
require the substantive rules of law of another jurisdiction to apply. Each
term, condition and provision of this Mortgage shall be interpreted in such
manner as to be effective and valid under applicable law but if any term,
condition or provision of this Mortgage shall be held to be void or invalid, the
same shall not affect the remainder hereof which shall be effective as though
the void or invalid term, condition or provision had not been contained herein.
Any procedures provided herein for such remedies shall be modified by and
replaced with, where inconsistent with or required by, any procedures or
requirements of the laws of the State of Indiana.

a national banking association with its principal office in Phoenix, Arizona

      all that real estate located in Middlesex County, Massachusetts, described

      Assignment of Rents and Fixture Filing (this "Mortgage") and incorporated

<PAGE>   2








      This Mortgage is given to secure all of the Obligations of Bowmar
Instrument Corporation, an Indiana corporation ("Borrower") to the Bank. The
term "Obligations" as used in this Mortgage means all obligations of the
Borrower in favor of the Bank of every type and description, direct or indirect,
absolute or contingent, due or to become due, now existing or hereafter arising,
including but not limited to all Obligations of the Borrower in favor of the
Bank arising under a Loan Agreement between the Borrower and the Bank dated the
date of this Mortgage (the "Loan Agreement"), which Obligations include the
obligation of the Borrower to repay all advances made by the Bank to the
Borrower under a revolving line of credit in the principal amount of
$4,000,000.00, to repay a term loan in the principal amount of $4,200,000.00,
and to repay all advances made by the Bank to Borrower under a non-revolving
acquisition line of credit in the principal sum of $1,000,000.00. The final
maturity date of the revolving line of credit is July 31, 1997, the final
maturity date of the term loan is July 31, 2000, and the final maturity date of
the non-revolving acquisition line of credit is July 31, 2001. All of the
Obligations, including those arising under the Loan Agreement, are secured as
they now exist and as they may be increased or otherwise changed by any
amendment to any instrument or agreement which now or hereafter evidences,
secures or expresses terms applicable to any of the Obligations, including
amendments to the Loan Agreement and any "Security Documents" as that term is
defined in the Loan Agreement.

      As additional security for the Obligations, the Mortgagor assigns to the
Bank the rents, issues and profits of the Mortgaged Premises, including any
rents and all other amounts (collectively "Lease Payments") which are due or
shall become due to the Mortgagor under the terms of any present or future lease
(a "Lease"), oral or written, of all or any portion of the Mortgaged Premises
(all such rents, issues, profits and Lease Payments are hereafter collectively
referred to as the "Rents"). This Assignment of Rents is an absolute assignment,
and is intended to vest in the Bank the right to collect all Rents subject only
to the conditional license to collect Rents granted by the Bank to the Mortgagor
under the terms of numbered Paragraph 7 of this Mortgage.

      The Mortgagor further covenants and agrees as follows:

      1. This Mortgage shall secure payment and performance of the Obligations,
with reasonable attorneys' fees and costs of collection, without relief from
valuation and appraisement laws.

      2. The Mortgagor shall keep the Mortgaged Premises in good repair and
shall not commit or permit waste thereon or do or permit to be done anything
that may impair the value of the Mortgaged Premises. The Mortgagor shall
promptly restore any part of the Mortgaged Premises which may be damaged or
destroyed, in a good and workmanlike manner and in conformity with the Americans
With Disabilities Act of 1990 and corresponding rules and regulations (the
"ADA") and with plans and specifications approved by Bank. The Mortgagor shall
pay when due all taxes and assessments levied or assessed against the Mortgaged
Premises or any part thereof.

      3. The Mortgagor shall comply with all statutes, ordinances, rules,
regulations, orders, and directions of any legislative, executive,
administrative, or judicial body or official applicable to the Mortgaged

                                       -2-


<PAGE>   3








Premises, or any part thereof, or to the Mortgagor, or to the operation of any
business of Mortgagor which directly affects the Mortgaged Premises; provided,
however, that the Mortgagor may contest any of the matters referred to in this
paragraph as provided in the Loan Agreement or otherwise in any reasonable
manner which in the judgment of the Bank will not adversely affect the rights of
the Bank, its successors or assigns.

      4. The Mortgagor will procure and maintain in effect at all times
insurance written by insurance companies acceptable to the Bank which insures
against loss or destruction of the Mortgaged Premises by fire, wind storm,
lightning, vandalism and malicious mischief and such other perils as are
generally covered by "extended coverage" insurance for the full replacement
value of the Mortgaged Premises. All policies providing such insurance shall
provide that any loss thereunder shall be payable to the Bank under a standard
form of secured lender's loss payable endorsement. The Mortgagor shall also
procure business interruption insurance in such amounts as the Bank may
reasonably require. The Mortgagor authorizes the Bank to endorse on Mortgagor's
behalf and to negotiate drafts representing proceeds of such insurance, provided
that the Bank shall remit to the Mortgagor such surplus, if any, as remains
after the proceeds have been applied at the Bank's option: (a) to the
satisfaction of the Obligations, whether or not then due and payable, or to the
establishment of a cash collateral account securing the Obligations, or (b) to
the restoration of the Mortgaged Premises. Certificates evidencing the existence
of all of the insurance required under the terms of this Mortgage shall be
furnished to the Bank and the original policies providing such insurance shall
be delivered to the Bank at the Bank's request. If the insurance proceeds are to
be used for the restoration and repair of the Mortgaged Premises, they shall be
held by Bank in an interest bearing account selected by Bank in its sole and
absolute discretion (the "Restoration Account"). Mortgagor, at its expense,
shall promptly prepare and submit to Bank all plans and specifications necessary
for the restoration and repair of the damaged Mortgaged Premises, together with
evidence acceptable to Bank setting forth the total expenditure needed for the
restoration and repair based upon a fixed price contract with a reputable
builder and covered by performance and labor and material payment bonds. The
plans and specifications and all other aspects of the proposed restoration and
repair shall be subject to Bank's approval. In the event the insurance proceeds
held in the Restoration Account are insufficient to complete the restoration and
repair, Mortgagor shall deposit in the Restoration Account an amount equal to
the difference between the amount then held in the Restoration Account and the
total contract price for the restoration and repair. Mortgagor may commence
restoration and repair of the damaged Mortgaged Premises only when authorized in
writing by Bank to do so and thereafter shall proceed diligently with the
restoration and repair until completed. Disbursements shall be made from the
Restoration Account for the restoration and repair in accordance with a
disbursement schedule, and subject to other terms and conditions, acceptable to
Bank. Disbursements from the Restoration Account shall be charged first against
funds deposited by Mortgagor and, after such funds are exhausted, against the
insurance proceeds deposited therein. In the event the amounts held in the
Restoration Account exceed the cost of the restoration and repair of the damaged
Mortgaged Premises, the excess funds shall be disbursed to Mortgagor to the
extent of any amounts deposited therein by Mortgagor. Any funds remaining after
such disbursement, at Bank's option, may be applied by Bank to the payment of
the Obligation, whether or not

                                       -3-


<PAGE>   4








then due, or may be disbursed to Mortgagor. All funds held in the Restoration
Account are hereby assigned to Bank as further security for the Obligation.
Bank, at any time, may apply all or any part of the funds held in the
Restoration Account to the curing of any Default.

      5. Upon demand and failure of the Mortgagor so to do, the Bank may, in its
discretion upon thirty (30) days notice to Mortgagor (unless Bank determines an
emergency exists in which case no notice shall be required), advance and pay all
sums necessary to protect and preserve the Mortgaged Premises, and all sums so
advanced and paid by the Bank shall become a part of the indebtedness secured
hereby, shall bear interest from date of payment at a rate equal to the Prime
Rate plus five and one half percent (5.5%) per annum, and shall be payable to
the Bank upon demand. Such sums shall include, but not by way of limitation: (a)
taxes, assessments and other charges which may be or become senior to this
Mortgage as liens on the Mortgaged Premises, or any part thereof; (b) the cost
of any title insurance, surveys, or other evidence which in the discretion of
the Bank may be required in order to evidence, insure or preserve the lien of
this Mortgage; (c) all costs, expenses, and reasonable attorneys' fees incurred
by the Bank in respect of any and all legal and equitable actions which relate
to this Mortgage or to the Mortgaged Premises, and (d) the cost of any repairs
respecting the Mortgaged Premises which are reasonably deemed necessary by the
Bank. As used in this Mortgage, the term "Prime Rate" means a variable per annum
rate of interest equal at all times to the rate of interest established and
quoted by the Bank as its Prime Rate, such rate to change contemporaneously with
each change in such established and quoted rate; provided that it is understood
the Prime Rate shall not necessarily be representative of the rate of interest
actually charged by the Bank on any loan or class of loans. The Bank shall be
subrogated to the rights of the holder of each lien or claim paid with moneys
secured hereby. Upon written request by Bank, Mortgagor shall appear in and
prosecute or defend any action or proceeding that may affect the lien or the
priority of the lien of this Mortgage or the rights of Bank hereunder and shall
pay all costs, expenses (including the cost of searching title) and attorneys'
fees incurred in such action or proceeding. Bank may appear in and defend any
action or proceeding purporting to affect the lien or the priority of the lien
of this Mortgage or the rights of Bank.

      6. If all or any part of the Mortgaged Premises is damaged, taken, or
acquired, either temporarily or permanently, in any condemnation proceeding, or
by exercise of the right of eminent domain, or by the alteration of the grade of
any street affecting the Mortgaged Premises, the amount of any award or other
payment for such taking or damages made in consideration thereof, to the extent
of the full amount of the then remaining unpaid Obligations, is hereby assigned
to the Bank, which is empowered to collect and receive the same and to give
proper receipts therefor in the name of the Mortgagor, and all such sums shall
be paid forthwith directly to the Bank. Any award or payment so received by the
Bank may, at the option of the Bank: (a) be applied to the satisfaction of the
Obligations, whether or not then due and payable, or to the establishment of a
cash collateral account for the Obligations, or (b) be released, in whole or in
part, to the Mortgagor for the purpose of altering, restoring, or rebuilding any
part of the Mortgaged Premises which may have been altered, damaged or destroyed
as a result of such taking, alteration, or proceeding.

                                       -4-

      7. At any time a Default (as hereafter defined) has occurred and is
continuing, the Bank may enter upon and take possession of the Real Estate or
any part thereof, and at any such time, or if the Bank in the reasonable
exercise of its discretion determines that payment or performance of any of the
Obligations is insecure, the Bank may demand, sue for, receive and give
receipts, releases and satisfactions for all Rents. At any time that the Bank
has not exercised its right to take possession of the Real Estate and there is
not in effect any demand by the Bank for the direct payment of Lease Payments to
the Bank given pursuant to the immediately preceding sentence, the Mortgagor may
collect Lease Payments provided that no Rents shall be collected by the
Mortgagor more than thirty (30) days in advance of the period of occupancy to
which they relate. Lease Payments collected by the Mortgagor pursuant to the
license granted in the immediately preceding sentence shall be held by the
Mortgagor as trustee for the benefit of the Bank and shall be applied to the
satisfaction of Obligations to the extent that any are then due and payable. Any
balance remaining after satisfaction of all Obligations which are then due and
payable may be used by the Mortgagor for any proper purpose. Any demand by the
Bank upon any tenant of the Mortgaged Premises accompanied by a copy of this
Mortgage shall be sufficient authority for such tenant thereafter to make all
Lease Payments directly to the Bank and any such tenant shall have no obligation
or authority to inquire into the propriety of any such demand. Upon making Lease
Payments to the Bank pursuant to the Bank's demand, any tenant of the Mortgaged
Premises shall be as fully discharged of its obligations under any Lease to the
extent of such payments as if such payments had been made directly to the
Mortgagor. If at any time Lease Payments are required to be made directly to the
Bank under the terms of this paragraph and notwithstanding such requirement such
payments are made to the Mortgagor, the Mortgagor will receive such payments in
trust for the Bank and will forward them immediately to the Bank in the form in
which received, adding only such endorsements or assignments as may be necessary
to perfect the Bank's title thereto. Any amounts collected by the Bank pursuant
to the assignment of rents contained in this Mortgage shall be applied by the
Bank to the payment of such of the Obligations as are then due and payable as
the Bank in its sole discretion shall determine. If no Obligations are then due
and payable, such amounts may be held by the Bank as cash collateral for the
Obligations, without liability for interest thereon, provided that the Bank
will, at the direction of the Mortgagor, invest such amounts for the account and
at the risk of the Mortgagor in U.S. Treasury Bills with less than 60 days
remaining to maturity or in similar essentially risk-free, cash equivalent
investments as the Mortgagor may reasonably direct and any earnings derived from
such investments will become a part of the cash collateral account. Any portion
or all of the cash collateral account which is not applied to Obligations
pursuant to the terms of this paragraph may at the discretion of the Bank be
released to the Mortgagor. The authority given to collect Rents conferred upon
the Bank under the terms of this Mortgage is irrevocable.

      8. The Mortgagor grants to the Bank as secured party a security interest
in the Personal Property in accordance with the provisions of the Uniform
Commercial Code as enacted in Massachusetts. The Mortgagor authorizes the Bank
at the expense of the Mortgagor to execute on its behalf and file any other
financing statements deemed necessary by the Bank to perfect its security
interest in the Personal Property and to file such financing statements in those
public offices deemed necessary by the Bank. Such financing statements may be

                                       -5-


<PAGE>   6








signed by the Bank alone. In addition, the Mortgagor shall execute and deliver
any financing statement or other document that the Bank may request to perfect
or to further evidence the security interest created by this Mortgage.

      9.    If, after the execution of this Mortgage, applicable law requires 
the taxation of this Mortgage, the Mortgagor, upon demand by the Bank, shall pay
such taxes or reimburse the Bank therefor unless it is unlawful to require the
Mortgagor to do so. Notwithstanding the foregoing, the Mortgagor shall not be
obligated to pay any portion of any of the Bank's federal or state income taxes.

<PAGE>   7








            (e) Release. "Release" means the spilling, leaking, disposing,
      discharging, dumping, pouring, emitting, depositing, injecting leaching,

            (f) Regulatory Actions. "Regulatory Actions" means any claim,

      limitation, any civil, criminal or administrative proceeding whether or
      not seeking costs, damages, penalties or expenses.

            (g) Third-party Claims. "Third-party Claims" means any claim,
      action, demand or proceeding, other than a Regulatory Action, based on
      negligence, trespass, strict liability, nuisance, toxic tort or detriment
      to human health or welfare due to Contamination, whether or not seeking
      costs, damages, penalties, or expenses, and including any action for
      contribution to Clean-up costs.

The Mortgagor shall indemnify, defend and hold harmless the Bank and its
affiliates, shareholders, directors, officers, employees and agents (all being
included in the word "Bank" for purposes of this paragraph) from any and all
claims, causes of action, damages, demands, fines, liabilities, losses,
penalties, judgments, settlements, expenses and costs, however defined, and of
whatever nature, known or unknown, absolute or contingent, including, but not
limited to, attorneys' fees, consultant's fees, fees of environmental or other
engineers, and related expenses including, without limitation, expenses related
to site inspections and soil and water analyses, which may be asserted against,
imposed on, suffered or incurred by the Bank arising out of or in any way
related to (a) any actual, alleged or threatened Release of any Hazardous
Substance on, in or under the Real Estate, (b) any related injury to human
health or safety (including wrongful death) or any actual or alleged injury to
the environment by reason of the condition of, or past or present activities on
the Real Estate, (c) any actual or alleged violation of Environmental Law
related to the Real Estate, (d) any lawsuit or administrative proceeding brought

a result of any Contamination or threat of Contamination, and (f) all costs and
expenses of any Clean-up. The Mortgagor represents and covenants that the
Mortgagor's storage, generation, transportation, handling or use, if any, of
Hazardous Substances on or from the Real Estate is currently, and will remain at
all times, in compliance with all applicable Environmental Laws. If any Clean-up
is required with respect to the Real Estate, the Mortgagor shall expeditiously
complete such Clean-up at the Mortgagor's expense and without the necessity of
demand by the Bank. If the Mortgagor should fail to initiate and diligently
pursue any Clean-up or should otherwise fail to perform any obligation under the
terms of this paragraph, the Bank may, at its sole discretion and without any
obligation to complete any Clean-up which it may cause to be commenced, cause
the Clean-up or partial Clean-up of the Real Estate and pay on behalf of the
Mortgagor any costs, fines or penalties imposed on the Mortgagor pursuant to any
Environmental Laws or make

                                       -7-


<PAGE>   8








any other payment or perform any other action which will prevent a lien in favor
of any federal, state or local government authority or any other person from
attaching to the Real Property pursuant to the provisions of any Environmental
Law, and all costs and expenses of the Bank incurred in pursuing any of the
remedies provided in this paragraph shall be added to the obligations secured by
this Mortgage, which costs and expenses shall become due and payable without
notice as incurred by the Bank, together with interest thereon at the Prime Rate
plus five and one half percent (5.5%) per annum until paid.

      11.   Without obtaining the prior written consent of Bank, Mortgagor shall
not sell, transfer, convey, assign or otherwise dispose of, or further encumber,
all or any part of the Mortgaged Premises or any interest therein, voluntarily
or involuntarily, by operation of law or otherwise. If Mortgagor is a
corporation, limited liability company, partnership, joint venture or trust, any
material change in the ownership or management of, or interest in, Mortgagor, or
any pledge or encumbrance of any interest in Mortgagor, shall be deemed to be a
transfer of the Mortgaged Premises. Upon the occurrence of any such transaction
with Bank's consent, or without Bank's consent if Bank elects not to exercise
its rights and remedies for an Event of Default, Bank (i) may increase the
interest rate on all or any part of the Obligations to its then current market
rate for similar indebtedness; (ii) may charge a loan fee and a processing fee
in connection with the change; and (iii) shall not be obligated to release
Mortgagor from any liability hereunder or for the Obligations except to the
extent required by law. Consent to any such transaction shall not be deemed to
be consent or a waiver of the requirement of consent to any other such
transaction.

      12.   The occurrence of any of the following events shall be deemed a
"Default" under this Mortgage:

            (a) an "Event of Default" as defined in the Loan Agreement shall
      have occurred and be continuing or the Borrower shall otherwise fail to
      pay or perform any of the Obligations promptly when such payment or
      performance is due or within such grace period as may be applicable;

            (b) the Mortgagor shall otherwise fail to observe and perform the
      terms and conditions of this Mortgage and such failure continues
      unremedied for a period of thirty (30) days after notice to Mortgagor;

            (c) the Mortgagor shall abandon the Mortgaged Premises;

            (d) Any levy or execution upon, or judicial seizure of, any portion
      of the Mortgaged Premises;

            (e) Any attachment or garnishment of, or the existence or filing of
      any lien or encumbrance other than as consented to by Bank against, any
      portion of the Mortgaged Premises, that is not removed or released within
      forty-five (45) days after its creation;

            (f) The institution of any legal action or proceedings to enforce
      any lien or encumbrance upon any portion of the Mortgaged

                                       -8-


<PAGE>   9








      Premises, that is not dismissed within forty-five (45) days after
      its institution;

            (g) The existence of any encroachment upon the Mortgaged Premises
      that has occurred without the approval of Bank that is not removed or
      corrected within thirty (30) days after its creation; or

            (h) The demolition or destruction of, or any substantial damage to,
      any portion of the Mortgaged Premises that is not adequately covered by
      insurance.

      13.   Upon the occurrence and continuance of a Default, all indebtedness
secured hereby shall, at the option of the Bank, become immediately due and
payable and this Mortgage may be foreclosed accordingly. Upon the occurrence and
continuance of a Default, the Bank shall be entitled to the appointment of a
receiver for the Mortgaged Premises to collect the rents and profits and to
maintain the Mortgaged Premises without regard to the adequacy of any security
for the Obligations or the solvency of Mortgagor or any other person or entity.
The Bank shall have the option of proceeding as to both the Real Estate and the
Personal Property in accordance with its rights and remedies in respect of the
Real Estate, in which event the default provisions of the Uniform Commercial
Code shall not apply. If the Bank elects to proceed with respect to the Personal
Property separately from the Real Estate, the requirement of the Uniform
Commercial Code as to reasonable notice of any proposed sale or disposition of
the Personal Property shall be met if such notice is delivered or mailed to the
Mortgagor at its address stated above at least five (5) days prior to such sale
or disposition. In any action to foreclose this Mortgage, the Bank shall be
entitled to recover, in addition to all reasonable attorney and related
paraprofessional expenses incurred in connection therewith, all other reasonable
costs and expenses associated with foreclosure including, without limitation,
all expenses incurred for title searches, abstracts of title, title insurance,
appraisals, surveys and environmental assessments reasonably deemed necessary by
the Bank, all of which costs and expenses shall be additional amounts secured by
this Mortgage. As used in the preceding sentence, the term "environmental
assessments" means inspections and reports of environmental engineers or firms
of environmental engineers or other appropriate experts, and associated
samplings and testings of soil or groundwater, the purpose of which is to
determine whether there is any Contamination associated with the Real Estate and
if so, the extent thereof, and to estimate of the cost of Clean-up of any
Contamination, and to determine whether there are any underground storage tanks
or any asbestos in, on, or under the Real Estate and if so, whether there are
any violations of Environmental Laws in connection therewith. As used in this
paragraph, the terms "Contamination," "Clean-up" and "Environmental Laws" are
used as defined in numbered Paragraph 10.

      14.   All rights, powers and remedies granted Bank herein, or otherwise
available to Bank, are for the sole benefit and protection of Bank, and Bank may
exercise any such right, power or remedy at its option and in its sole and
absolute discretion without any obligation to do so. In addition, if, under the
terms hereof, Bank is given two or more alternative courses of action, Bank may
elect any alternative or combination of alternatives, at its option and in its
sole and absolute discretion. All monies advanced by Bank under the terms hereof

                                       -9-


<PAGE>   10








and all amounts paid, suffered or incurred by Bank in exercising any authority
granted herein, including reasonable attorneys' fees, shall be added to the
Obligation, shall be secured by this Mortgage, shall bear interest at a rate
equal to the Prime Rate plus five and one half percent (5.5%) per annum until
paid, and shall be due and payable by Mortgagor to Bank immediately without
demand.

      15. In order to insure the payment of taxes and assessments that are now,
or hereafter may be, a lien upon the Mortgaged Premises, and to insure the
payment of all premiums on policies of insurance required herein, Mortgagor, if
required by Bank after the occurrence of a Default, shall pay to Bank each
month, in addition to any other payments required hereunder, an amount equal to
the taxes and special assessments levied or to be levied against the Mortgaged
Premises and the premium or premiums that will become due and payable to
maintain the insurance on the Mortgaged Premises, all as reasonably estimated by
Bank (giving due consideration to the previous year's taxes, assessments and
premiums) less all deposits therefore already made, divided by the number of
months remaining before one month prior to the date when the taxes, assessments
and premiums become delinquent. If amounts paid to Bank under the terms of this
paragraph are insufficient to pay all taxes, assessments and premiums as they
become due, Mortgagor shall pay to Bank upon demand all additional sums
necessary to fully pay and discharge these items. All moneys paid to Bank under
the terms of this paragraph may be either held by Bank to pay the taxes,
assessments and premiums before the same become delinquent or applied to the
Obligation upon payment by Bank from its own funds of the taxes, assessments and
premiums. To the extent provision is not made for payment pursuant to this
paragraph, Mortgagor shall remain obligated to pay all taxes, assessments and
premiums as they become due and payable. Deposits made under this paragraph may
be commingled with Bank's general funds; Bank shall have no liability to
Mortgagor for interest on any deposits.

      16. The Bank, at its option and on such terms as it may desire, may renew,
compromise, accelerate, extend or otherwise change the time of payment or
performance, or otherwise change the terms, of any part or all of the
Obligations or release any obligated party or collateral, or any part of the
Mortgaged Premises from the lien of this Mortgage without impairing the lien of
this Mortgage except as to the portion of the Mortgaged Premises expressly
released and without releasing the Mortgagor or any guarantors or sureties of or
from any of the obligations. No delay by the Bank in the exercise of any of its
rights under this Mortgage shall preclude the subsequent exercise thereof so
long as any Default continues uncured, and no waiver by the Bank of any Default
of the Mortgagor shall operate as a waiver of subsequent or other Defaults. The
making of any payment by the Bank for any of the purposes herein permitted shall
not constitute a waiver of any breach of the Mortgagor's covenant to perform
such act. Notice by the Bank of its intention to exercise any right or option
under this Mortgage is expressly waived by the Mortgagor, and any one or more of
the Bank's rights or remedies under this Mortgage may be enforced successively
or concurrently. Mortgagor waives and agrees not to assert: (i) any right to
require Bank to proceed against Borrower or any guarantor, to proceed against or
exhaust any other security for the Obligations, to pursue any other remedy
available to Bank, or to pursue any remedy in any particular order or manner;
(ii) the benefits of any legal or equitable doctrine or principle of
marshalling;

                                      -10-


<PAGE>   11








(iii) the benefits of any statute of limitations affecting the enforcement
hereof; (iv) demand, diligence, presentment for payment, protest and demand, and
notice of extension, dishonor, protest, demand and nonpayment, relating to the
Obligations; (v) any benefit of, and any right to participate in, any other
security now or hereafter held by Bank (vi) the benefits of any statutory
provision limiting the liability of a surety, including without limitation the
benefit of Section 12-1641, et seq., of the Arizona Revised Statutes; and (vii)
any defense arising by reason of any disability or other defense of Borrower or
by reason of the cessation from any cause whatsoever of the liability of
Borrower. Mortgagor shall have no right of subrogation and hereby waives any
right to enforce any remedy which Bank now has, or may hereafter have, against
Borrower. Time is of the essence of this Mortgage.

      17. All advances of principal under the Note shall be made to Borrower
subject to and in accordance with the terms thereof. If Borrower is a
corporation or partnership, it is not necessary for Bank to inquire into the
powers of Borrower or the officers, directors, partners or agents acting or
purporting to act on its behalf. Mortgagor is and shall continue to be fully
informed as to all aspects of the business affairs of Borrower that it deems
relevant to the risks it is assuming and hereby waives and fully discharges Bank
from any and all obligations to communicate to Mortgagor any facts of any nature
whatsoever regarding Borrower and Borrower's business affairs.

      18. Bank shall have the right to inspect the Mortgaged Premises at all
reasonable times.

      19. Notwithstanding anything to the contrary contained herein, Bank
acknowledges that a prior mortgage has been recorded against the Mortgaged
Premises (herein called the "Prior Mortgage"). The indebtedness and obligations
secured by the Prior Mortgage are hereinafter called the "Prior Obligation."
Mortgagor shall make all payments of principal and interest on the Prior
Obligation as they become due. Without the prior written consent of Bank,
Mortgagor shall not consent or agree to or request any increase in the amount of
the Prior Obligation, any extension of time for the payment thereof, any
reduction in any payment required thereon, or any postponement, modification or
indulgence thereof, and shall not sign a renewal note or notes therefor.

      20. Should there occur any default in any payment or performance of the
Prior Obligation, then Bank, without notice to or demand upon Mortgagor and
without releasing Mortgagor from any obligation, may pay or perform the Prior
Obligation in such manner and to such extent as it may deem necessary; Bank is
hereby authorized to enter upon the Mortgaged Premises for such purposes. In
addition, upon the occurrence of any Default and at any time while such Default
is continuing, Bank, at any time and from time to time, may prepay the Prior
Obligation in whole or in part together with all premiums, penalties or other
payments required in connection with any such prepayment. The exercise of any
right or authority herein granted shall not cure or waive any Default nor
invalidate any act done hereunder because of any Default.

      21. The occurrence of a default in any of the terms, conditions or
provisions of the Prior Mortgage shall constitute a Default hereunder that shall

                                      -11-


<PAGE>   12








entitle Bank to immediately exercise its rights and remedies set forth herein
for a Default.

      22. All obligations of the Mortgagor under this Mortgage shall extend to
and be binding upon the successors and assigns of the Mortgagor, and shall inure
to the benefit of the Bank and its successors and assigns.

      23. This Mortgage secures indebtedness incurred for a business purpose.

      24. The Obligations and the agreements of any person or entity to pay or
perform the Obligations shall be governed by and construed according to the laws
of the State of Arizona, provided, that this Mortgage shall be governed by and
construed according to the substantive laws of the State of Massachusetts,
notwithstanding the fact that Massachusetts conflicts of law rules might
otherwise require the substantive rules of law of another jurisdiction to apply.
Each term, condition and provision of this Mortgage shall be interpreted in such
manner as to be effective and valid under applicable law but if any term,
condition or provision of this Mortgage shall be held to be void or invalid, the
same shall not affect the remainder hereof which shall be effective as though
the void or invalid term, condition or provision had not been contained herein.
Any procedures provided herein for such remedies shall be modified by and
replaced with, where inconsistent with or required by, any procedures or
requirements of the laws of the State of Massachusetts.

      25. This Mortgage is upon the STATUTORY CONDITION for breach of which and
for breach of any other condition herein, the Bank shall have the STATUTORY
POWER OF SALE.

      Dated:  August 28, 1995.
