</TABLE>

                  During the fiscal year ended June 30, 1997 ("fiscal 1997"),
the Company continued its efforts to expand its business in two product lines,
the Temperature /Humidity Monitoring Systems product line and the Geiger Muller
Tube product line, and committed additional resources to upgrade its Nucleonic
Gauges product line.

                  In July 1995 the Company entered into an operating agreement
for the formation of a New Jersey limited liability company (the "LLC"). The
purpose of the LLC is to develop, manufacture, produce and sell
Temperature/Humidity Monitoring Systems and other related

                                       -3-

<PAGE>



products or services. Pursuant to a contribution agreement among the Company and
the other members of the LLC, the Company contributed property, in the form of
cash, inventory and other business assets with a fair market value of $300,000,
in exchange for a 42% membership interest in the LLC. The Company will produce
under a manufacturing agreement the Temperature/Humidity Monitoring Systems
which will be sold by the LLC and will provide administrative services to the
LLC. At June 30, 1997, the LLC's backlog for Temperature/Humidity Monitoring
Systems was $897,000 compared to $17,000 at June 30, 1996. Included in the
backlog at June 30, 1997 is $731,000 of orders which require customer approval
of trial units prior to shipment of production units. Substantially all such
orders are subject to cancellation.

                  In addition to its efforts to expand its business in its
Temperature/Humidity Monitoring Systems product line, the Company has continued
marketing Geiger Muller Tubes for both military and commercial markets. The
Company believes that the discrete sale of such radiation detectors represents a
continuing diversification of its product line. At June 30, 1997 backlog for
Geiger Muller Tubes was $122,000 compared to $73,000 at June 30, 1996.

                  During fiscal 1997, the Company dedicated resources toward
broadening and updating its Nucleonic Gauges product line. At June 30, 1997
backlog for Nucleonic Gauges was $46,000 compared to $28,000 at June 30, 1996.


                  In 1986 the Company obtained two United States patents that
are significant to its business. One patent covers a radiation measurement
apparatus that utilizes a technique used in certain of the Company's Health
Physics and Environmental Monitoring devices. The technique of operation, as
described in the patent, permits more extensive use of a stable, inexpensive
radiation detector that, prior to the invention, was limited to a comparatively
narrow scope of


                                       -4-

<PAGE>



use. The possession of this patent allows the Company, in a protected fashion,
to compete in a much broader market. The second patent covers an apparatus that
utilizes a computer program that permits more accurate measurement of radiation
in connection with the apparatus covered by the first patent and is an
improvement over the devices covered by the first patent. The second patent
allows the Company to address additional business opportunities in specialized
low level nuclear measurement. The Government has certain use rights with
respect to these patents. The Company also has obtained corresponding patents in
certain foreign countries. During 1991, the Company obtained a United States
patent relating to a radiation measurement device used in connection with other
products manufactured by the Company. The patents obtained in the United States
have a life of 17 years from the date of grant.

                  (c) Distribution. The Company's products are marketed directly
to its customers through its own marketing staff and through a variety of
manufacturers' representatives acting as independent commissioned sales agents
and distributors. Commissions range from 3% to 15% depending upon the amount of
follow-up service provided. In certain instances, where opportunities for growth
or expansion are unique, the Company has tailored its agreements with such
representatives with a view to enhance sales efforts. Approximately 75% of all
sales in fiscal 1997 were obtained through the Company's internal marketing
staff which currently consists of seven persons.

                  (d) Backlog. At June 30, 1997, the Company's backlog of orders
was $18,795,000 compared to $19,195,000 at June 30, 1996. Substantially all such
orders are subject to cancellation. Included in the backlog at June 30, 1997 is
a $3,900,000 contract with a South Korean company which was awarded to the
Company but not signed as of June 30, 1997. The contract was signed on September
18, 1997. The Company expects to ship approximately


                                       -5-

<PAGE>



$8,000,000 of the June 30, 1997 backlog in the fiscal year ended June 30, 1998
("fiscal 1998"). Also included in the backlog of orders at June 30, 1997 and
1996, respectively, is $4,200,000 and $7,300,000 which represents the unfunded
amount on a Government contract awarded in May 1996.

                  The Company was awarded a $10,600,000 contract by the United
States Army in May 1996. The Government exercised options and the current value
of the contract is $11,050,000. The contract represents a continuation of the
Company's manufacturing for the United States Army of a next generation product
that utilizes the Company's patented technique of radiation measurement. The
Company experienced difficulty completing the first article and anticipates
(although there is no assurance of) first article completion by October 1997. In
such event, shipments are expected to commence in the second quarter of fiscal
1997.

                  The recent completion of several Government contracts may
continue to reduce sales and earnings over one or more succeeding quarters and
until existing backlog and new orders are sufficient to reverse the trend.

                  Domestic commercial orders for fiscal 1997 were $2,325,000
compared to $3,022,000 for the fiscal year ended June 30, 1996 ("fiscal 1996").
The Company believes that the decrease in domestic commercial orders is
primarily attributable to customer budget constraints which have delayed orders.

                  (e) Sources of Supply. The Company's products are manufactured
from widely distributed electronic components and fabricated parts made of
metal, plastics and rubber. Nuclear materials are used to calibrate the products
or to create a radiation source for checks or measurements, but are not normally
used in the manufacturing process. Required materials and


                                       -6-

<PAGE>



components have been readily available from multiple sources at competitive
prices and the Company foresees no significant problem of availability.

                  (f) Competitive Conditions. The Company has a limited number
of competitors in each of its product categories. Certain of these companies
have greater capital and technical resources than the Company. Competition in
each of the Company's product categories is based primarily upon price,
technology and ability to deliver.

                  (g) Customers. Contracts with the Government, including the
United States Department of Defense, decreased from 65.1% of revenues in fiscal
1996 to 31.9% of revenues in fiscal 1997. The decrease resulted from the
fulfillment of certain multi-year contracts and difficulties encountered
completing the first article for a major Government contract. Some of the
products manufactured for the Government are proprietary and others are
manufactured in accordance with Government specifications and drawings. All of
the Company's contracts with the Government provide for termination at the
discretion of the Government for reasons of convenience and/or justifiable
cause. Only four of the Government contracts accepted by the Company in its
47-year history have been terminated by the Government. The final negotiated
settlements in three of those instances did not result in a material loss of
profits on completed portions of the contracts because earned profits were paid
up to the points of termination. However, termination does cause a reduction in
backlog and in projected revenues and profits from the terminated portion of the
contract.

                  The Government and one foreign power company are the only
customers that accounted for at least 10% of the Company's total revenues in
fiscal 1997. The loss or significant reduction of Government contract work would
be likely to have a material adverse effect on the Company.


                                       -7-

<PAGE>



                  Total foreign shipments accounted for 44% of the Company's
total revenues in fiscal 1997 as compared to 26% in fiscal 1996 and 12% in the
fiscal year ended June 30, 1995 ("fiscal 1995").

                  Domestic commercial sales for fiscal 1997 increased to
$2,931,000 compared to $2,296,000 for fiscal 1996. The increase in domestic
commercial sales can be accounted for by an increase in the previous year's
domestic commercial orders.

                  All of the Company's sales to unaffiliated customers are
manufactured in and shipped from the United States. Export sales information
appears below:

                  (h) Regulation. The United States Nuclear Regulatory
Commission ("USNRC") imposes controls on the handling of nuclear materials,
including disposal of material waste and toxic material discharge, as well as
security against loss or theft of nuclear material and the protection of
personnel in or near nuclear environments. The Company is subject to these
regulations and has on staff a qualified health physicist who serves as the
Company's radiation safety officer and supervises the Company's compliance. He
is responsible for the preparation,


                                       -8-

<PAGE>



updating and implementation of the Company Radiation Safety Handbook, a copy of
which is on file with the USNRC. The USNRC periodically conducts spot
inspections to determine compliance with its regulations and license
requirements.

                  The Company considers the maintenance and upgrading of these
controls as well as the maintenance of adequate storage facilities to be normal
costs of business. The Company believes its current facilities and
administrative procedures meet USNRC requirements.

                  The Company holds licenses granted by the USNRC for the
receipt, use, storage and distribution of various radioisotope source materials
used in its normal course of business. Each of the licenses is for a term of
five years. Prior to their expiration, two licenses were renewed for an
additional five year term. The expiration dates of the licenses are: April 30,
2000; September 30, 2000; January 31, 2001; November 30, 2002; October 31, 2004.

                  Radiac (radiation detection, identification and computation)
instruments for military use constitute a portion of the Company's foreign
sales. Approval by the Office of Munitions Control of the United States
Department of State is required prior to the issuance of an export license for
such instruments. The Office of Munitions Control can impose certain
restrictions on the sale of these instruments.

                  (i) Research and Development. The Company has a six person
staff consisting of electronics engineers, nuclear physicists and computer
programmers who perform research and development activities for the Company.
This group spends from 80% to 85% of its time on a project basis in development
of special products for customers and new and improved products for the
Company's own product lines.

                  The Company expended $1,054,389 on research in fiscal 1997
compared to $1,096,206 and $1,052,718 in fiscal years 1996 and 1995,
respectively. Customer-sponsored research accounted for $0 in fiscal 1997,
$97,382 in fiscal 1996 and $187,854 in fiscal 1995.

                  (j) Personnel. At September 1, 1997, the Company had a total
of 132 full-time employees, consisting of 82 employees at the Company's
Warrington, Pennsylvania location and 50 employees at the Company's Dover, New
Jersey location. Of these employees, 64 are engineering and production workers
and the balance are officers, managers, clerical personnel and indirect labor.
None of the Company's employees are represented by a labor union.


Item 2. Properties.

                  On March 23, 1981, the Company purchased a building at 125
Titus Avenue, Warrington, Pennsylvania for use as the Company's headquarters and
as a manufacturing facility. The building, which is located on a three-acre
site, originally contained approximately 29,000 square feet with approximately
8,000 square feet reserved for offices and engineering laboratories and 21,000
square feet for manufacturing facilities. During fiscal 1996, the Company
completed construction of a 20,000 square foot addition to the Warrington
facility to accommodate increased space requirements and to provide space for
growth. During fiscal 1997, the Company completed additional work in connection
with the new addition, including interior finishing, plumbing and electrical
work, expansion of existing parking lots and installation of exterior lighting.

                  On January 15, 1982, the Company leased 38,000 square feet of
space on the second floor of a building on Richboynton Road in Dover, New
Jersey, to be used for offices, engineering laboratories and manufacturing
facilities. The lease term was for a period of ten years with a five-year
renewal option which was exercised, effective March 1, 1992. The lease


                                      -10-

<PAGE>



expired effective February 28, 1997 and the Company executed a new, two year
lease for the same space, plus an additional 10,000 square feet for storage,
effective March 1, 1997. The new lease provides the Company with three one-year
renewal options. See Note 8 to the Consolidated Financial Statements.

                  The Company believes that its properties are adequate to meet
its current requirements.


Item 3. Legal Proceedings.

                  In September 1995, the Company's management ("Management") was
notified that the LLC, Mark A. Sitcoske and a company controlled by Mr.
Sitcoske, Measurement Dynamics, Inc., had been named as co-defendants in a suit
filed on September 7, 1995 in the Superior Court of the State of Rhode Island by
Hanna Manufacturing, Inc. ("Hanna"), a Rhode Island Company that previously
employed Mr. Sitcoske. The suit alleges that the defendants acted in violation
of an existing employment and non-compete agreement between Hanna and Mr.
Sitcoske and seeks to enjoin Mr. Sitcoske from his continued employment with the
LLC and to obtain damages; however, Hanna has not yet sought a hearing to obtain
injunctive relief. The matter is now in discovery and Management expects that
the resolution of this matter will have no material impact on the Company.

(1)   During fiscal 1994, the final settlement of the Company's insurance
      claim related to the partial roof collapse at the Dover Division in
      March 1993 resulted in a recorded gain of $323,209.

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

Liquidity and Capital Resources

                  During fiscal 1997, reductions in costs and estimated earnings
in excess of billing on uncompleted contracts of $2,962,602 combined with an
increase in prepaid taxes on income and tax refund receivables of $849,522 were
the principal factors which affected the cash provided by operating activities.
The decrease in costs and estimated earnings in excess of billings on
uncompleted contracts is primarily attributable to the shipments of several
multi-year contracts during fiscal 1997. The costs and estimated earnings in
excess of billings on uncompleted contracts resulted from the Company's use of
the percentage of completion method for income recognition of several multi-year
contracts. See Note 1 to the Consolidated Financial Statements. The increase in
prepaid taxes on income and tax refund receivable is primarily the


                                      -13-

<PAGE>



result of the tax benefit associated with the net loss in fiscal 1997 combined
with the payment of estimated taxes. Increases in inventory of $454,903 combined
with decreases in accounts receivable of $862,763 and accrued expenses and
payroll taxes of $393,014 partially offset cash provided by operating activities
for fiscal 1997. The increase in inventory can be attributed primarily to (a) a
major new Government contract scheduled to ship during fiscal 1998 and (b)
delays in shipment of several commercial contracts. The decrease in accounts
receivable is primarily attributable to substantially higher sales in fiscal
1996 as compared to fiscal 1997. The decrease in accrued expenses and payroll
taxes resulted primarily from a reduction of accrued commission expenses and the
repayment of an outstanding liability.

                  The Company made capital expenditures in fiscal 1997 in the
aggregate amount of $277,323 to purchase manufacturing and computer equipment
and to make certain expenditures associated with patents. Additionally, $411,086
was expended on the 20,000 square foot addition to the Company's Warrington
facility. Cash used by financing activities for fiscal 1997 decreased to
$101,408 as a result of proceeds on long-term debt in the amount of $511,816
partially offset by payments on long-term debt of $613,224.

                  During fiscal 1997, the Company increased its working capital
line of credit to $5,500,000 of which $3,325,000 was outstanding at June 30,
1997. The interest rate on this line of credit is payable at the prime rate (8
1/2% as at June 30, 1997) of the Company's lender (the "Bank"). The line of
credit is collateralized by accounts receivable, inventory, property, plant and
equipment, assignment of a letter of credit confirmed and negotiated by the
Bank, assignment of all existing and future Government contracts that exceed
$500,000 and the guaranty of the Company's wholly-owned subsidiary, NRC
Acquisition Corp. ("NRC"), and the LLC. The maximum amount guaranteed by the LLC
is $400,000. The maximum amount


                                      -14-

<PAGE>



available for advances under this line of credit is limited to certain standby
letters of credit issued as collateral for performance on long-term contracts
and bids. The value of these standby letters of credit was $272,622 at June 30,
1997. See Notes 4 and 8 to the Consolidated Financial Statements.

                  The Company also has a long-term note with the Bank at an
interest rate of 8.25%. The note is collateralized by accounts receivable,
inventory, property, plant and equipment and assignment of a letter of credit
confirmed and negotiated by the Bank. The principal balance of this loan at June
30, 1997 was $141,666. See Note 5 to the Consolidated Financial Statements.

                  On January 14, 1997, the Company entered into a $1,800,000
term loan with repayment based on a five year term, with interest at 7.85% per
annum. In June 1997, the Company negotiated with the Bank the terms of a
Commercial Promissory Note Modification Agreement pursuant to which the
principal amount of the term loan note was reduced to $400,000, the amount of
monthly principal payments thereon was reduced from $20,000 to $8,750 and the
term of the loan was reduced from five years to three years. The note is
collateralized by accounts receivable, inventory, property, plant and equipment,
assignment of a letter of credit confirmed and negotiated by the Bank,
assignment of all existing and future Government contracts that exceed $500,000
and the guaranty of NRC and the LLC. The purpose of this loan is to assist in
financing the working capital requirements of the LLC. The principal balance of
this loan at June 30, 1997 was $271,520. See Note 5 to the Consolidated
Financial Statements.


                                      -15-

                  The Company believes that, notwithstanding the Company's
recent performance, funds from operations and amounts available under its
present credit facilities will be sufficient to satisfy the Company's operating
cost requirements in the current fiscal year.

Results of Operations

                  The Company experienced disappointing results in both sales
and earnings during fiscal 1997, in part due to (a) completion of several
Government contracts, (b) decreased sales resulting from the Company's inability
to ship a new product to the Government during the fiscal year, (c) customers'
budget constraints, which have delayed orders, and (d) a lower order base which
Management believes is due to competitive conditions. The aforementioned new
product that the Company was unable to ship to the Government during fiscal 1997
is currently in the first article stage of testing and requires Government
approval prior to shipment. The Company anticipates (although there is no
assurance) that shipments of this product will commence in the second quarter of
fiscal 1998.

                  The Company anticipates that it will continue to show a net
loss for at least the first two quarters of fiscal 1998 due to (a) its inability
to ship the new product to the Government during the first quarter, to date, in
fiscal 1998, as discussed above, (b) a decrease in orders received during fiscal
1997, (c) delays in the shipment of several commercial contracts, (d) delays in
the Company's realization of the benefits of its cost reduction efforts and (e)
the Company's continued investments toward the growth of the LLC and the
development of opportunities for growth, particularly with respect to its Geiger
Muller Tubes and Nucleonic Gauge product lines.

                  In January 1997, the Company entered into a term loan in the
amount of $1,800,000, of which amount $1,400,000 was committed for the Company's
acquisition of two


                                      -16-

<PAGE>



companies with which it was then in negotiations. Both acquisition attempts
failed and the principal amount of the term loan note was reduced to $400,000.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operation--Liquidity and Capital Resources." However, the Company continues to
seek acquisition opportunities. In addition, the Company anticipated, but did
not realize, significant growth for the LLC as well as for the Company's Geiger
Muller Tube and Nucleonic Gauge product lines.

                  In July 1997, the Company reduced its work force in accordance
with reduced sales levels.


Fiscal 1997 Compared with Fiscal 1996

                  Sales for fiscal 1997 decreased to $12,202,559 from
$25,100,604 for fiscal 1996. The decrease in sales in fiscal 1997 is
attributable to the factors discussed above. See "Management's Discussion and
Analysis of Financial Condition and Results of Operation--Results of
Operations."

                  Income (loss) from operations decreased to a loss of
$2,214,398 in fiscal 1997 from income of $2,312,394 in fiscal 1996 because of
reduced sales. Due to reduced sales, gross profit as a percentage of sales
decreased to 17.57% as compared to 27.06% for fiscal 1996.

                  Selling and administrative expenses increased $49,534 to
$3,076,612 in fiscal 1997. Due to reduced sales, as a percentage of sales,
selling and administrative expenses increased to 25.21% for fiscal 1997 as
compared to 12.06% for fiscal 1996.

                  During fiscal 1997, the Company continued its practice of
investing in the development of new technologies and new applications of its
existing technologies in an effort to create new business opportunities.
Research and development expenses decreased $41,817 to $1,054,389 for fiscal
1997. Due to reduced sales, as a





                                      -17-

<PAGE>

percentage of sales, research and development expenses increased to 8.64% for
fiscal 1997 as compared to 4.37% for fiscal 1996.

                  Interest expenses decreased $130,268 to $227,128 for fiscal
1997 as a result of decreased borrowings and a reduction in related costs
associated with a letter of credit for a multi-year contract.

                  The effective tax rate increased from 36% in fiscal 1996 to
39% in fiscal 1997.

                  FAS 106 - Post Retirement Benefits Other than Pensions and FAS
109 - Accounting for Income Taxes have been issued and are effective for the
years beginning after December 15, 1992. In the opinion of Management, the
adoption of these pronouncements has not had a material effect on the Company's
financial position or its results of operations.



Fiscal 1996 Compared with Fiscal 1995


                  Sales for fiscal 1996 decreased to $25,100,604 from
$27,051,737 for fiscal 1995. The decrease in sales in fiscal 1996 was primarily
due to the completion of several Government contracts. However, the Company's
aggressive marketing efforts in foreign markets resulted in an increase in
foreign sales of 105% from $3,132,000 in fiscal 1995 to $6,427,000 in fiscal
1996.
                  Income from operations increased to a record $2,312,394 in
fiscal 1996 from $2,034,346 in fiscal 1995. The increase in income from
operations was primarily due to an increase in shipments of a particular product
line with higher gross margins (which resulted in a more favorable product mix)
which was partially offset by an increase in selling and administrative
expenses. Gross profit as a percentage of sales increased to 27.06% for fiscal
1996 as compared to 20.07% for fiscal 1995.

                  Selling and administrative expenses increased $994,761 to
$3,027,078 in fiscal 1996. The increase was primarily due to increased
commission expenses and costs associated


                                      -18-

<PAGE>



with the LLC. As a percentage of sales, selling and administrative expenses
increased to 12.06% for fiscal 1996 as compared to 7.51% for fiscal 1995.

                  During fiscal 1996, the Company continued its practice of
reinvesting part of its earnings to develop new technologies and new
applications of its existing technologies in an effort to create new business
opportunities. Research and development expenses increased $43,488 to $1,096,206
for fiscal 1996. The amount of research and development expenses funded
internally for new product development was $998,824 in fiscal 1996, compared to
$864,864 in fiscal 1995. As a percentage of sales, research and development
expenses increased to 4.37% for fiscal 1996 as compared to 3.89% for fiscal
1995.

                  Interest expenses increased $48,650 to $357,396 for fiscal
1996 as a result of higher borrowings and related costs associated with letters
of credit for several multi-year contracts.

                  The effective tax rate decreased from 38% in fiscal 1995 to
36% in fiscal 1996.

                  FAS 106 - Post Retirement Benefits Other than Pensions and
FAS 109 - Accounting for Income Taxes have been issued and are effective for the
years beginning after December 15, 1992. In the opinion of Management, the

(1) There is no trading market for the Company's securities. The fair market
value of the Company's Common Stock is determined by the book value of the
Company's Common Stock. On June 30, 1997, the book value of the Company's Common
Stock was $220.09 per share.

(2) See Item 13 "Certain Relationships and Related Transactions" for a
description of warrants for the purchase of the Company's Common Stock that were
granted to Earl M. Pollock in connection with and as partial consideration for a
loan to the Company by Mr. Pollock and the execution of a non-recourse surety
agreement by Mr. Pollock as security for the Company's credit facilities.

Employment Contracts and Change-in-Control Arrangements

                  On July 1, 1995, the Company entered into a seven-year
employment agreement with Harold J. Cooley. Pursuant to the employment
agreement, Mr. Cooley is presently entitled to receive base compensation at the
annual rate of $235,040. In addition, at the end of each fiscal year Mr. Cooley
is eligible for a bonus based on certain performance-based criteria. In the
event that the Company terminates Mr. Cooley's employment without cause, the
Company is required to continue to pay Mr. Cooley's base compensation,
determined in accordance with the agreement, for the full term of the agreement.
In the event that Mr. Cooley's employment is terminated due to death, the
Company is required to continue to make all payments otherwise payable pursuant
to the agreement to Mr. Cooley or his beneficiary, as applicable, for a period
of one year following his death. If Mr. Cooley's employment is terminated due to
disability, the Company's sole obligation is to pay Mr. Cooley's last full
year's base compensation for one year following termination due to disability.

                  If the Company merges or consolidates with a company that
controls over 50% of the voting control of the Company or is acquired by any
party not an affiliate of the Company, the Company may terminate the employment
agreement and Mr. Cooley's employment. In the event of such termination, the
Company is required to pay Mr. Cooley his accrued base compensation plus a sum
equal to his most recent two full years' base compensation. One half of such sum
must be paid within thirty days of termination and the balance must be paid
within thirteen months of termination.

Compensation of Directors

                  Charles H. Sulzberger receives a fee of $500 per meeting of
the Board of Directors that he attends. During fiscal 1997, the Company paid
fees in the aggregate amount of $1,500 to Mr. Sulzberger.

Item 13.          Certain Relationships and Related Transactions.

                  In connection with and as partial consideration for a loan
from the Company's President, Earl M. Pollock, which loan was repaid in fiscal
1993, the Company issued to Earl M. Pollock in March 1989 warrants for the

share multiples at $100 per share. The warrants initially were to expire on

consideration for a non-recourse surety agreement executed by Earl M. Pollock as
security for the Company's credit facilities, the Company issued to Mr. Pollock

exercisable in 1,000 share multiples at $160.28 per share. The

To the Board of Directors
Nuclear Research Corporation
Warrington, Pennsylvania

                          Independent Auditors' Report

               We have audited the accompanying consolidated balance sheets of
Nuclear Research Corporation and Subsidiaries as of June 30, 1997 and 1996 and
the related consolidated statements of operations, stockholders' equity and cash
flows for each of the years in the three-year period ended June 30, 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the consolidated
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 financial position of
Nuclear Research Corporation and Subsidiaries as of June 30, 1997 and 1996 and
the results of their operations and their cash flows for each of the three years
in the period ended June 30, 1997 in conformity with generally accepted
accounting principles.

                  NUCLEAR RESEARCH CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1997


NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

              Organization

              Nuclear Research Corporation (the Company) was incorporated on
              July 17, 1950 under the laws of the Commonwealth of Pennsylvania.
              The Company is engaged in the business of designing, manufacturing
              and servicing detection, measurement and monitoring devices and
              gauges for customers throughout the world, with a majority of its
              revenue derived from products primarily manufactured for use by
              the United States Department of Defense.

              Principles of Consolidation

              The consolidated financial statements include the accounts of
              Nuclear Research Corporation (the parent), NRC Acquisition
              Corporation and Northeast Nuclear, Ltd., wholly-owned
              subsidiaries, and Measurement Dynamics LLC (MDLLC), owned 42% by
              Nuclear Research Corporation, hereafter referred to collectively
              as the "Company". All significant intercompany accounts and
              transactions have been eliminated in consolidation. Northeast
              Nuclear, Ltd. is a foreign sales corporation (FSC) and as such
              files its own corporate tax return. MDLLC is a limited liability
              company (LLC) and as such files its own partnership tax return
              (see Note 11). MDLLC now has a deficit in its equity account;
              therefore, according to generally accepted accounting principles,
              the liability in minority interest in equity of consolidated
              subsidiary has been reduced to zero on the consolidated balance
              sheet at June 30, 1997.

              Use of Estimates

              Management uses estimates and assumptions in preparing these
              financial statements in accordance with generally accepted
              accounting principles. Those estimates and assumptions affect the
              reported amounts of assets and liabilities, the disclosure of
              contingent assets and liabilities, and the reported revenues and
              expenses. Actual results could vary from estimates that were used.

              Accounting for Contracts

              Substantially all of the Company's contracts are firm-fixed price.
              The units of delivery method (a modification of the percentage-of-
              completion method) recognizes as revenue the contract price of
              units delivered during a period and recognizes the costs allocable
              to the delivered units. Estimates of cost to complete are reviewed
              and revised periodically throughout the lives of the contracts,
              and adjustments to profit resulting from such revisions are
              recorded in the accounting period in which the revisions are made.
              Losses on specific contracts are recorded by charging any amounts
              in excess of estimated realizable value to cost of sales as they
              are identified.

                  NUCLEAR RESEARCH CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                  JUNE 30, 1997


NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

              The Company recognizes revenues on several fixed-price contracts
              using the percentage-of-completion method, measured by the
              percentage of cost incurred to date compared to the estimated
              total cost for the contracts. That method is used because
              management considers total cost to be the best available measure
              of progress on the contracts. Because of inherent uncertainties in
              estimating costs, it is at least reasonably possible that the
              estimates used will change within the near term.

              Contract costs include all direct material, direct labor and
              indirect costs related to contract performance. Provisions for
              estimated losses on uncompleted contracts are made in the period
              in which such losses are determined. Changes in estimated job
              profitability resulting from job performance, job conditions,
              claims, change orders, and settlements are accounted for in the
              period in which the changes occur.

              The asset, "Costs and estimated earnings in excess of billings on
              uncompleted contracts," represents revenues recognized in excess
              of amounts billed.

              Costs, estimated earnings, and billings on uncompleted contracts
              at June 30 are summarized as follows:

</TABLE>

              The Company does not provide an allowance for doubtful accounts
              because of the composition of its customer base, the use of
              irrevocable letters of credit for export sales and the lack of any
              significant uncollectible amounts in prior years.

              Inventory

              Inventories, other than inventoried costs relating to long-term
              contracts, are stated at the lower of cost (principally last-in,
              first-out - LIFO) or market and include material, labor and
              factory overhead. Market represents the lower of replacement cost
              or estimated net realizable value (see Note 2). Inventoried costs
              relating to long-term contracts are stated at the actual
              production cost including factory overhead incurred to date,
              reduced by amounts identified with revenue recognized on delivered
              units. The costs attributed to delivered units under long-term
              contracts are based on the estimated average cost of all
              manufactured units.

              Property, Plant and Equipment

              Property, plant and equipment are stated at cost. Expenditures for
              maintenance and repairs are charged against operations. Renewals
              and betterments that materially extend the life of the assets are
              capitalized (see Note 3). Depreciation and amortization are
              computed using straight-line and accelerated methods over the
              estimated useful lives of the related assets.

NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

              The cost of the patents and trademarks are being amortized using
              the straight line method over their remaining useful lives, not to
              exceed seventeen years. Accumulated amortization was $90,821 at
              June 30, 1997 and $74,943 at June 30, 1996. Amortization expense
              amounted to $13,559, $13,956 and $12,261 in 1997, 1996 and 1995,
              respectively.

              The cost of the copyrights is being amortized using the straight
              line method over their remaining useful lives, which has been
              determined by management to be five years. Accumulated
              amortization was $736 at June 30, 1997 and $368 at June 30, 1996.
              Amortization expense was $368 for both the years ended June 30,
              1997 and 1996 and $-0- for the year ended June 30, 1995.

              Other intangible assets represent the assets contributed to MDLLC
              by the minority members of the LLC and include products, product
              ideas and various trade names. The assets are being amortized
              using the straight line method over their remaining useful lives,
              not to exceed nineteen years. Accumulated amortization was $41,083
              at June 30, 1997 and $20,383 at June 30, 1996. Amortization
              expense was $20,700, $20,383 and $-0- for the years ended June 30,
              1997, 1996 and 1995, respectively.

              Income Taxes

              Deferred income taxes are recorded based upon differences between
              the financial statement and the tax basis of assets and
              liabilities. The temporary differences include the inclusion of
              the loss from MDLLC in the consolidated tax returns of the parent
              corporation, depreciation from an involuntary conversion of
              property and state net operating loss carryovers (see Note 11).

              Research and Development

              Research and development costs related to both present and future
              products are charged to operations as incurred. These costs
              amounted to $1,054,389, $1,096,206 and $1,052,718 in 1997, 1996
              and 1995, respectively. Customer-sponsored research accounted for
              $-0-, $97,382 and $187,854 in 1997, 1996 and 1995, respectively.

              Earnings Per Share

              The Company uses the last-in, first-out (LIFO) method to determine
              its material inventory costs, because it results in a better
              matching of costs and revenues. The following information will
              facilitate comparison with operating results of companies using
              the FIFO method. If the Company's inventory had been determined
              using the FIFO method at June 30, 1997 and 1996, reported
              inventories would have been higher by $1,143,627 and $1,026,228,
              respectively. Reported net income for the year ended June 30, 1997
              would have increased by $72,487 ($2.12 per share). Reported net
              income for the year ended June 30, 1996 would have decreased by
              $1,617 ($.05 per share). Reported net income for the year ended
              June 30, 1995 would have increased $92,119 ($2.76 per share). The
              proforma effect relating to the use of the FIFO method would have
              resulted in the following balances for the consolidated statements
              of operations presentation for the years ended June 30, 1997, 1996

</TABLE>

              In the year ended June 30, 1996, a reduction in inventory resulted
              in a liquidation of LIFO inventory carried at lower costs in prior
              years as compared with the cost of 1996 purchases. The effect of
              this liquidation was to increase net income by $96,663 ($2.75 per
              share).

NOTE 9 - FAIR VALUE OF FINANCIAL INSTRUMENTS

              The following methods and assumptions were used to estimate the
              fair value of each class of financial instruments for which it is
              practicable to estimate that value:


              Long-Term Debt

              The fair value of the corporation's long-term debt is estimated
              based on the quoted market prices for the same or similar issues
              or on the current rates offered to the corporation for debt of the
              same remaining maturities.

              The estimated fair values of the corporation's financial
              instruments are as follows:

                                             1997                  1996

                                 Exhibit 10(w)




                COMMERCIAL PROMISSORY NOTE MODIFICATION AGREEMENT


                  This Agreement dated the 29th day of September, 1997 by and
between CoreStates Bank, N.A., a national banking association, with offices at
4259 West Swamp Road, Doylestown, Pennsylvania, 18901 ("Bank") and Nuclear
Research Corporation, a Pennsylvania corporation, having its principal place of
business at 125 Titus Avenue, Warrington, Pennsylvania, 18974 ("Borrower").


                                   Background

                  A. Bank and Borrower entered into a loan agreement on or about
January 14, 1997 pursuant to which Bank agreed to lend to Borrower the sum of
One Million Eight Hundred Thousand Dollars ($1,800,000.00) ("Loan") upon certain
terms and conditions for use by the Borrower in connection with the acquisition
of the business assets of one company, the acquisition of the assets of a
second company and the restructuring of advances by Borrower to Measurement
Dynamics LLC.

                  B. In connection with the aforesaid Loan Borrower executed a
Note dated January 14, 1997 in favor of Bank in the original principal amount of
One Million Eight Hundred Thousand Dollars ($1,800,000.00) (the "Note"), the
terms of which are incorporated herein by reference.

                  C. The Note is secured by, inter alia, a Mortgage dated
January 14, 1997, executed and delivered by Borrower to Bank and securing the
principal sum of One Million Eight Hundred Thousand Dollars ($1,800,000.00),
which Mortgage encumbers the property of Borrower known as 125 Titus Avenue,
Warrington, Bucks County, Pennsylvania, (the "Property") and was recorded in the
Office for the Recorder of Deeds of Bucks County, Pennsylvania, at Land Record
Book Page (the "Mortgage").

                  D. The Note is further secured by Guaranty Agreements, in
favor of Bank, executed by N.R.C, Acquisition Corp., a Pennsylvania corporation
and Measurement Dynamics LLC, a New Jersey limited liability company (herein the
"Guarantors"), executed on January 14, 1997.

                  E. The Note, Mortgage, and all other documents executed and
delivered in connection with the Loan, as modified, are hereinafter referred to
individually as a "Loan Document" and collectively as the "Loan Documents". The
property secured by the Mortgage shall be referred to herein as the "Mortgaged
Property".

                  F. By the terms of the Note, Borrower is obligated to tender
monthly installments of principal each in the amount of Twenty Thousand Dollars
($20,000.00) and payment of the entire principal balance outstanding as of
January 14, 2002.

                                       -1-


<PAGE>



                  G. Borrower did not complete the acquisitions for which the
Loan proceeds were advanced and therefore a significant portion of the principal
sum was not advanced to Borrower.

                  H. Borrower and Bank desire to amend the Loan Documents in
order to reduce the amount of the monthly installments of principal, reduce the
term of the Loan, carry forward the liens against the Mortgaged Property and to
make other necessary modifications, all on the terms and conditions set forth
herein.

                  NOW THEREFORE, INTENDING TO BE LEGALLY BOUND HEREBY, and in
consideration of the mutual covenants and promises contained herein, Bank and
Borrower hereby agree to modify the Note dated on or about January 14, 1997, as
follows:

                 1. Section (a) of the Note is hereby modified as follows:

                           (a) Commencing on the effective date of this
Modification Agreement and thereafter on the same day of each succeeding month,
Borrower shall repay the then outstanding principal balance of the Loan in
thirty-two (32) equal successive monthly installments of principal each in the
amount of Eight Thousand Seven Hundred Fifty Dollars ($8,750,00), together with
interest monthly on the outstanding principal balance at the fixed rate of 7.85%
per annum. If not sooner paid the entire principal balance outstanding and all
accrued but unpaid interest shall be due and payable in full no later than
January 14, 2000.

                 2. Borrower hereby represents and warrants that as of the date
hereof:

                                    (i) The current outstanding principal
balance of the Note as of the effective date of this Modification Agreement is
Two Hundred Eighty Thousand Dollars ($280,000.00);

                                    (ii) No default or event of default exists
under the Loan Documents, including the Note, Mortgage, or any other Loan
Document, and there exists no condition which, but for the passage of time or
the giving of notice, or both, would constitute a default under the Loan
Documents, including the Note, the Mortgage, or any other Loan Document;

                                    (iii) There are no set-offs or defenses
which Borrower has against the enforcement of the Note, the Mortgage, or any
other Loan Documents; and

                                    (iv) The Mortgage Modification Agreement
dated even date herewith is not intended to have any effect upon the lien
priority of the Mortgage or to impair the security of any other lienholder.

                 3. As a condition precedent to the execution by Bank of this
Agreement, Borrower agrees to the following:

                                       -2-


<PAGE>




                                    (i) The Mortgage shall continue to be a
fourth lien mortgage against the property which it encumbers.

                                    (ii) Borrower agrees to pay all fees and
expenses of Bank in connection with the issuance and preparation of this
Agreement, including all legal fees.

                                    (iii) Borrower shall obtain the consent of
the Guarantors to this Agreement.

                 4. Except as expressly extended and amended by this
Modification Agreement, the Note, Mortgage, and other Loan Documents shall
remain in full force and effect pursuant to their respective terms. This
Modification Agreement is not intended to be nor shall it constitute a novation
of the Note or any other Loan Document or the indebtedness and obligations
evidenced or secured thereby, as the case may be. Borrower hereby ratifies,
confirms and approves the Note, Mortgage, and other Loan Documents, as modified
by this Modification Agreement, and the indebtedness and obligations evidenced
and/or secured thereby and Borrower agrees that the same shall constitute valid
and binding, agreements of Borrower, enforceable in accordance with their
respective terms. All references to the Loan Documents contained in the Note,
Mortgage, and any other Loan Documents shall be deemed to refer to such
documents as amended and extended by this Modification Agreement,

                 5. Borrower hereby represents, warrants and reaffirms to Bank
that it is the intention of the parties to this Modification Agreement that all
existing collateral security held by the Bank shall continue to serve as
collateral for the Note and any other liabilities due the Bank by the Borrower
pursuant to the Note and other Loan Documents, and, until the Loan is paid in
full, the security interests and mortgages held by the Bank shall otherwise
continue in full force and legal effect.

                 6. This Agreement shall be effective as of June 14, 1997.

                 7. All provisions of this Modification Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
heirs, administrators, successors and assigns. This Modification shall be
governed by and construed in accordance with the laws of the Commonwealth of
Pennsylvania. Borrower hereby acknowledges receipt of a true copy of this
Agreement.
