                                     PART I
 
ITEM 1:  BUSINESS
 
     Teradyne, Inc. is a manufacturer of electronic test systems and backplane
connection systems used in the electronics and telecommunications industries.
For financial information concerning these two industry segments, see "Note L:
Industry Segment and Geographic Information" in Notes to Consolidated Financial
Statements. Unless the context indicates otherwise, the term "Company" as used
herein includes Teradyne, Inc. and all its subsidiaries.
 
ELECTRONIC TEST SYSTEMS
 
     The Company designs, manufactures, markets, and services electronic test
systems and related software used by component manufacturers in the design and
testing of their products and by electronic equipment manufacturers for the
incoming inspection of components and for the design and testing of circuit
boards and other assemblies. Manufacturers use such systems and software to
increase product performance, to improve product quality, to shorten time to
market, to enhance manufacturability, to conserve labor costs, and to increase
production yields. The Company's electronic systems are also used by telephone
operating companies for the testing and maintenance of their subscriber
telephone lines and related equipment.
 
     Electronic test systems produced by the Company include: (i) test systems
for a wide variety of semiconductors, including digital and analog integrated
circuits, (ii) test systems for circuit boards and other assemblies, and (iii)
test systems for telephone lines and networks. The Company's test systems are
all controlled by computers, and programming and operating software is supplied
both as an integral part of the product and as a separately priced enhancement.
 
     The Company's systems are extremely complex and require extensive support
both by the customer and by the Company. Prices for the Company's systems range
from less than $100,000 to $5 million or more.
 
BACKPLANE CONNECTION SYSTEMS
 
     The Company also manufactures backplane connection systems, principally for
the computer, telecommunications, and military/aerospace industries. A backplane
is a panel that supports the circuit boards in an electronic assembly and
carries the wiring that connects the boards to each other and to other elements
of a system. The Company produces both printed circuit and metal backplanes,
along with mating circuit-board connectors. Backplanes are custom-configured to
meet specific customer requirements. The Company has begun to extend the
manufacture of backplane connection systems to include the manufacture of fully
integrated electronic assemblies that incorporate backplane, card cage, cabling,
and related design and production services.

                              MARKETING AND SALES
 
MARKETS
 
     The Company sells its products across most sectors of the electronics
industry and to companies in other industries that use electronic devices in
high volume. The Company believes that it could suffer the loss of one or even a
few major customers without serious long-term adverse effects. Sales to
Motorola, Inc. were approximately 10% of net sales in 1994. No other customer
accounted for more than 10% of net sales in 1994.
 
     Direct sales to United States government agencies accounted for less than
1% of net sales in 1994 and about 2% of net sales in 1993 and 1992. Sales are
also made within each of the Company's segments to customers who are government
contractors. About 22% of backplane connection systems sales and less than 10%
of electronic test systems sales fell into this category during 1994.
 
     The Company's international customers are located primarily in Europe, the
Asia Pacific region, and Japan. The Company sells in these areas both directly
and through foreign sales subsidiaries. Substantially all of the Company's
manufacturing activities are conducted in the United States.
 
     Sales to international customers accounted for 46% of net sales in 1994,
41% in 1993, and 42% in 1992. Identifiable assets of the Company's foreign
subsidiaries, consisting principally of operating assets, approximated $86.6
million at December 31, 1994, $65.0 million at December 31, 1993, and $86.0
million at December 31, 1992. Of these identifiable assets at December 31, 1994,
$42.6 million were in Europe, $40.3 million were in Japan, and $3.4 million were
in the Asia Pacific region. Since sales to international customers have little
correlation with the location of manufacture, it is not meaningful to present
operating profit by geographic area.
 
     The Company is subject to the inherent risks involved in international
trade, such as political instability, restrictive trade policies, controls on
funds transfer, and foreign currency fluctuations. The Company attempts to
reduce the effects of currency fluctuations by hedging part of its exposed
position and by conducting some of its foreign transactions in U.S. dollars or
dollar equivalents.
 
DISTRIBUTION
 
     The Company sells its electronic systems primarily through a direct sales
force. Backplane connection systems are sold by direct sales personnel as well
as by manufacturers' representatives. The Company has sales and service offices
throughout North America, Europe, the Asia Pacific region, and Japan.
 
COMPETITION
 
     Competition is intense in each of the business areas that the Company
operates. In each market there are several significant competitors. Many of
these competitors have greater resources than the Company. Competition is
principally based on technical performance, equipment and service reliability,
reputation and accessibility to the vendor, and price. While relative positions
vary from year to year, the Company believes that it operates with a significant
market share position in each of its businesses.
 
                                    BACKLOG
 
     On December 31, 1994, the Company's backlog of unfilled orders for
electronic test systems and backplane connection systems was approximately
$337.8 million and $76.2 million, respectively, compared with $238.9 million and
$49.1 million, respectively, on December 31, 1993. Of the backlog at December
31, 1994, approximately 92% of the electronic test systems backlog, and
approximately 91% of the backplane connection systems backlog are expected to be
delivered in 1995. The Company's past experience indicates that a portion of
orders included in the backlog may be canceled. There are no seasonal or unusual
factors related to the backlog.

                                 RAW MATERIALS
 
     The Company's products require a wide variety of electronic and mechanical
components. In the past, the Company has experienced occasional delays in
obtaining timely delivery of certain items. Additionally, the Company could
experience a temporary adverse impact if any of its sole source suppliers ceased
to deliver products. Management believes, however, that alternate sources could
be developed.
 
                              PATENTS AND LICENSES
 
     The development of products by the Company, both hardware and software, is
largely based on proprietary information. The Company protects its rights in
proprietary information through various methods such as copyrights, trademarks,
patents and patent applications, software license agreements, and employee
agreements.
 
                                   EMPLOYEES
 
     As of December 31, 1994, the Company employed approximately 4,000 persons.
Since the inception of the Company's business, there have been no work stoppages
or other labor disturbances. The Company has no collective bargaining contracts.
 
                     ENGINEERING AND DEVELOPMENT ACTIVITIES
 
     The highly technical nature of the Company's products requires a large and
continuing engineering and development effort. Engineering and development
expenditures for new and improved products were approximately $70.4 million in
1994, $62.4 million in 1993, and $62.0 million in 1992. These expenditures
amounted to approximately 10% of net sales in 1994, 11% in 1993, and 12% in
1992.
 
                             ENVIRONMENTAL AFFAIRS
 
     The Company's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment, particularly from plant wastes
and emissions. These include laws such as the Comprehensive Environmental
Response, Compensation and Liability Act of 1980 ("CERCLA"), the Occupational
Safety and Health Act, the Clean Air Act, the Clean Water Act, the Hazardous and
Solid Waste Amendments of 1984 and Resource Conservation and Recovery Act of
1976. In the opinion of management, the costs associated with complying with
these laws and regulations has not had and will not have a material effect upon
the capital expenditures, earnings and competitive position of the Company.

     The number of record holders of the Company's Common Stock at February 24,
1995 was 3,056.
 
     The Company has never paid cash dividends because it has been its policy to
use earnings to finance expansion and growth. While payment of future dividends
will rest within the discretion of the Board of Directors and will depend, among
other things, upon the Company's earnings, capital requirements and financial
condition, the Company presently expects to retain all of its earnings for use
in the business.

RESULTS OF OPERATIONS:
 
  1994 compared to 1993
 
     Sales increased 22% in 1994 to $677.4 million. Sales increased in each of
the major product lines of the Company -- semiconductor test systems,
circuit-board test systems, telecommunications systems and backplane connection
systems. The largest increases in sales occurred in semiconductor test systems,
which increased 22%, and backplane connection systems, which increased 48%.
Sales of semiconductor test systems grew as semiconductor manufacturers
continued to add capacity in response to rising demand for their products. This
capacity expansion was evidenced by a number of new semiconductor manufacturing
plants coming on line. Sales of backplane connection systems increased in
response to the rising demand for the high technology products in the Company's
commercial customer base. As a result of the increase in sales, income before
extraordinary item almost doubled in 1994, increasing $35.0 million to $70.9
million.
 
     Incoming orders grew faster than sales in 1994, increasing 28% to $803.4
million. The increase in orders, like the increase in sales, was primarily due
to increases in semiconductor test system orders, which increased 49%, and in
backplane connection systems, which increased 55%. As a result of the increase
in orders, the Company's backlog grew 44% in 1994, finishing the year at $414.0
million.
 
     Cost of sales as a percentage of sales decreased from 57% in 1993 to 56% in
1994. The improvement was the result of the following two factors. First, the
increase in sales volume permitted increased utilization of certain fixed and
semi-variable components of the Company's overhead structure. Second, there was
an unfavorable change in mix as sales of backplane connection systems, whose
product margins are generally lower than those of electronic test systems, were
higher as a percentage of total Company sales.

     Engineering and development expenses declined as a percentage of sales from
11% in 1993 to 10% in 1994, as these expenses did not increase at the same rate
as sales. The dollar amount of these expenses grew $8.1 million in 1994 as a
result of increased investment in new product development of semiconductor test
systems. Selling and administrative expenses decreased to 20% of sales in 1994
compared with 23% of sales in 1993, as the dollar volume of these expenses grew
less than 3% while sales increased 22%.
 
     Interest income increased 75% in 1994 to $6.4 million due to an increase in
the Company's average cash balance and higher interest rates during the year.
Interest expense decreased from $3.6 million in 1993 to $1.7 million in 1994 as
a result of the Company's retirement of its 9.25% convertible subordinated
debentures in the fourth quarter of 1993.
 
     The Company's effective tax rate was 31% in 1994 compared with 30% in 1993.
The Company was able to operate with an effective tax rate below the federal
statutory rate of 35% in both years through the utilization of tax credit
carryforward and foreign loss carryforward amounts. The Company expects its tax
rate to approximate the statutory rate of 35% in 1995.
 
  1993 Compared to 1992
 
     Sales increased 5% in 1993, to $554.7 million. The increase in sales was
primarily due to a 13% increase in sales of semiconductor test systems and, to a
lesser extent, a 7% increase in sales of backplane connection systems. Sales of
semiconductor test systems increased as semiconductor manufacturers added
capacity in response to rising demand for their products. Sales of circuit-board
test systems and telecommunications systems declined 7% and 18%, respectively,
in 1993 compared to 1992. Incoming orders increased 19% in 1993 to $625.0
million over 1992 with increased orders occurring in each of the Company's major
groups. The Company's backlog grew during 1993 to $288.0 million.
 
     Income before taxes increased by $25.3 million from 1992 to 1993 on a sales
increase of $25.2 million as the Company continued to control the growth in its
operating expenses. In addition, costs in 1993 were lower in the Company's
circuit-board test operations following actions taken by the Company in 1992 to
reduce the size of operations. These lower costs helped to offset the impact of
the reduced sales of circuit-board test systems.
 
     Cost of sales decreased from 59% of sales in 1992 to 57% in 1993. While
sales increased in 1993, the fixed and semi-variable components of cost of sales
decreased as a result of the Company's cost reduction programs. The changes in
engineering and development expenses and selling and administrative expenses
were each less than 1% in 1993, compared with 1992. These expenses were
essentially flat for the period 1991 through 1993 as the Company controlled the
growth of its fixed costs.
 
     Interest income increased 44% in 1993 as a result of a $76.2 million
increase in the Company's cash and cash equivalents balance during the year.
Interest expense decreased 12% in 1993 primarily as a result of the Company's
retirement of its 9.25% outstanding convertible subordinated debentures in the
fourth quarter.
 
     The Company's effective tax rate increased from 13.5% in 1992 to 30% in
1993. The Company was able to utilize net operating loss carryforwards to lower
its United States taxable income for financial reporting purposes in 1992, while
in 1993 the U.S. carryforwards were no longer available. However, the Company's
tax rate in 1993 was below the United States statutory rate of 35%, as a result
of the utilization of tax credit carryforwards and foreign net operating loss
carryforwards. The Company adopted Statement of Financial Accounting Standards
No. 109 "Accounting for Income Taxes" at the beginning of 1993. The effect of
this change in accounting principle was not material to the Company's
consolidated financial position. See "Note K: Income Taxes" in Notes to
Consolidated Financial Statements.
 
     In connection with the retirement of the Company's outstanding 9.25%
convertible subordinated debentures, the Company incurred, in the fourth quarter
of 1993, an extraordinary charge of $0.7 million, net of income taxes, for the
costs of the redemption premium of 3.7% and the writeoff of unamortized debt
issuance costs.

LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's cash balance grew $39.2 million in 1994 following an increase
of $76.2 million in 1993. Cash flow generated from operations was $89.4 million
in 1994 and $91.8 million in 1993. Additional cash of $25.3 million in 1994 and
$33.6 million in 1993 was generated from the sale of stock to employees,
including the related tax benefit, under the Company's stock option and stock
purchase plans.
 
     Cash was used to fund additions to property, plant and equipment of $29.6
million in 1994 and $32.2 million in 1993. The total capital spending over the
two years of $61.8 million was less than depreciation expense, creating a
decrease in the Company's net investment in property plant and equipment.
Property, plant and equipment declined from $185.1 million at the beginning of
1993 to $183.6 million at the end of 1994. The Company also invested $19.8
million in a U.S. Treasury Bill. In 1993 the Company's Board of Directors
authorized the repurchase of 1,000,000 shares of the Company's stock on the open
market. Cash of $24.6 million in 1994 and $2.3 million in 1993 was utilized for
this buyback of the Company's stock. Cash was also used to retire debt of $1.6
million in 1994 and $14.7 million in 1993. The debt retirement in 1993 included
$10.8 million for the repurchase of the Company's outstanding convertible
debentures.
 
     The Company believes its cash and cash equivalents balance of $182.8
million, together with other sources of funds, including marketable securities
of $19.8 million, cash flow generated from operations, and the available
borrowing capacity of $80.0 million under its line of credit agreement, will be
sufficient to meet working capital and capital expenditure requirements in 1995.
 
     Inflation has not had a significant long-term impact on earnings. If there
was inflation, the Company's efforts to cover cost increases with price
increases could be frustrated in the short-term by its relatively high backlog.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
A.  ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of Teradyne,
Inc. and its subsidiaries, all of which are wholly owned (referred to
collectively in these notes as the "Company"). All significant intercompany
balances and transactions are eliminated. Certain prior years' amounts have been
reclassified to conform to the current year presentation.
 
  Inventories
 
     Inventories are stated at the lower of cost (first-in, first-out basis) or
market (net realizable value).
 
  Property, Plant and Equipment
 
     Property, plant and equipment are stated at cost. Leasehold improvements
and major renewals are capitalized and included in property, plant and equipment
accounts while expenditures for maintenance and repairs and minor renewals are
charged to expense. When assets are retired, the assets and related allowances
for depreciation and amortization are eliminated from the accounts and any
resulting gain or loss is reflected in operations.
 
     The Company provides for depreciation of its property principally on the
straight-line method by charges to expense which are sufficient to write-off the
cost of the assets over their estimated useful lives.
 
  Revenue Recognition
 
     Revenue is recorded when products are shipped or, in instances where
products are configured to customer requirements, upon the successful completion
of test procedures. Service revenue is recognized ratably over applicable
contract periods or as services are performed. In certain situations, revenue is
recorded using the percentage of completion method based upon the completion of
measurable milestones, with changes to total estimated costs and anticipated
losses, if any, recognized in the period in which determined.
 
  Engineering and Development Costs
 
     The Company's products are highly technical in nature and require a large
and continuing engineering and development effort. All engineering and
development costs are expensed as incurred.
 
  Income Taxes
 
     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes." Under
SFAS 109, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse. The measurement of deferred tax
assets is reduced by a valuation allowance if, based upon weighted available
evidence, it is more likely than not that some or all of the deferred tax assets
will not be realized.
 
     The Company's practice is to provide U.S. federal taxes on undistributed
earnings of the Company's foreign sales and service subsidiaries.
 
  Translation of Foreign Currencies
 
     Assets and liabilities of foreign subsidiaries which are denominated in
foreign currencies are remeasured into U.S. dollars at rates of exchange in
effect at the end of the fiscal year except fixed assets which are remeasured
using historical exchange rates. Revenue and expense accounts are remeasured
using an average of exchange rates in effect during the year. Net realized and
unrealized gains and losses resulting from foreign currency remeasurement are
included in operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
A.  ACCOUNTING POLICIES - (CONTINUED)
  Net Income Per Common Share
 
     Net income per common share is based upon the weighted average number of
common and common equivalent shares (when dilutive) outstanding each year.
Common equivalent shares result from the assumed exercise of outstanding stock
options. The proceeds of which are then assumed to have been used to repurchase
outstanding common stock at the average market price during the year.
 
B.  FINANCIAL INSTRUMENTS
 
  Fair Value
 
     The Company considers all highly liquid temporary cash investments with
maturities of three months or less at date of acquisition to be cash
equivalents. At December 31, 1994 marketable securities consist of a short-term
investment in a U.S. Treasury Bill with an original maturity of greater than
three months. Marketable securities and cash equivalents are carried at
amortized cost plus accrued interest, which approximates fair value. The
Company's debt consists of subsidized loans whose fair value is not practicable
to estimate. For all other balance sheet financial instruments, the carrying
amount approximates fair value.
 
  Off-Balance Sheet Risk
 
     The Company regularly enters into forward foreign exchange contracts in
European and Japanese currencies to hedge assets, liabilities, and transactions
denominated in foreign currencies, for periods consistent with its committed
exposures. These contracts are used to reduce the Company's risk associated with
exchange rate movements, as gains and losses on these contracts are intended to
offset foreign exchange losses and gains on the assets, liabilities, and
transactions being hedged. Forward foreign exchange contracts have maturities of
less than one year, unless they relate to long term sales contracts denominated
in foreign currency; these maturities are from one to three years.
 
     At December 31, 1994 and 1993, the face amount of forward foreign exchange
contracts outstanding was $67.9 million and $51.9 million, respectively. The
fair value of such contracts at December 31, 1994, determined by applying the
year end foreign currency exchange rates to the contract amounts, was
immaterial.
 
     The Company's policy is to defer gains and losses on these contracts until
the corresponding losses and gains are recognized on the items being hedged.
During 1994, the Company recorded in other current assets a $2.9 million loss on
a deferred forward foreign exchange contract relating to a long term sales
contract denominated in foreign currency. This loss will serve to offset foreign
exchange transaction gains to be recognized on the contract revenue.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash investments and trade
accounts receivable. Concentrations of credit risk with respect to trade
accounts receivable are limited due to the large number of diverse and
geographically dispersed customers. The Company maintains cash investments
primarily in U.S. government obligations which essentially have no credit risk.

                                                                   ------     ------
                                                                   $8,806     $9,138
                                                                   ======     ======

 
     The total maturities of long-term debt for each of the next five years are
$0.3 million.
 
  Revolving Credit Agreement
 
     The Company has $80.0 million of revolving credit available through January
31, 1996 under a domestic line of credit agreement with its banks. Under the
terms of the agreement, any amounts outstanding at January 31, 1996 are
converted into a one year term note. As of December 31, 1994, no amounts were
outstanding under this agreement. The terms of this line of credit include
restrictive covenants regarding working capital, tangible net worth and
leverage. Interest rates on borrowings are either at the stated prime rate or
based upon Eurocurrency or certificate of deposit interest rates. Additional
borrowings up to $30.0 million are permitted outside the agreement provided that
the liabilities of the Company, exclusive of deferred income taxes and
subordinated debt, shall not exceed 100% of the Company's tangible net worth.
 
  Mortgage Note Payable
 
     The Company received a loan of $4.5 million from the Boston Redevelopment
Authority in the form of a 3% mortgage loan maturing March 31, 2013. This loan
is collateralized by a mortgage on the Company's property at 321 Harrison Avenue
which may, at the Company's option, become subordinated to another mortgage up
to a maximum of $5.0 million. Interest for the first 4 1/2 years of the note was
capitalized up to a principle amount of $5.0 million. Since September 30, 1987,
the Company has been making semi-annual interest payments.
 
  Other Long-term Debt
 
     At December 31, 1994, other long-term debt consists of a Japanese
yen-denominated note with an interest rate of 4.8%, secured by land in Kumamoto,
Japan, with interest only payable until March 31, 1995, and principal and
interest payable in monthly installments from April 28, 1995 to March 30, 2007.
 
  Short-term Borrowings
 
     The weighted average interest rate on short-term borrowings outstanding as
of December 31, 1994 and 1993 was 3.2% and 3.4%, respectively.

D.  CONVERTIBLE SUBORDINATED DEBENTURES
 
     During 1993, $5.0 million principle amount of debentures was converted into
210,585 shares of common stock resulting in an increase of $4.7 million of
shareholders' equity (net of the related $0.3 million unamortized debt issue
costs). On November 19, 1993, the Company exercised its option to repurchase the
remaining $10.4 million outstanding debentures. The Company used $10.8 million
of available cash from operations to repurchase the debentures at a premium of
103.7% of the principal amount. The premium amount and the write-off of the
remaining unamortized debt issue cost resulted in a charge of $1.0 million. This
charge, net of the related taxes of $0.3 million, is reflected as an
extraordinary loss in the Consolidated Statements of Income.
 
E.  COMMITMENTS
 
     Rental expense for the years ended December 31, 1994, 1993, and 1992 was
$10.2 million, $11.2 million, and $12.6 million, respectively. Minimum annual
rentals under all noncancellable leases are: 1995 - $6.5 million; 1996 - $3.2
million; 1997 - $1.7 million; 1998 - $1.4 million; 1999 - $1.1 million; and $5.7
million thereafter, totaling $19.6 million. Offsetting the future lease
payments, the Company's income from noncancellable subleases totals $0.7
million.

F.  PENSION PLANS
 
     The Company has defined benefit pension plans covering substantially all
domestic employees and employees of certain international subsidiaries. Benefits
under these plans are based on the employee's years of service and compensation.
The Company's funding policy is to make contributions to the plans in accordance
with local laws and to the extent that such contributions are tax deductible.
The assets of the plans consist primarily of equity and fixed income securities.
 
     The components of net pension expense are summarized as follows (in
thousands):
 


                                                               1994       1993       1992

     In accordance with the provisions of Financial Accounting Standards No. 87,
the Company recorded a minimum pension liability adjustment of $6.8 million at
December 31, 1993, representing the excess of accumulated benefit obligations
over the fair value of plan assets and accrued pension liabilities. The
additional liability was offset by an intangible asset to the extent of
previously unrecognized prior service cost of $4.6 million. The amount in excess
of previously unrecognized prior service cost was recorded as a reduction of
shareholder's equity in the amount of $1.5 million, net of applicable deferred
income taxes of $0.7 million. In 1994, this adjustment was reversed as the plan
assets exceeded the accumulated benefit obligation.
 
     In addition to the above plans, the Company in 1993 established an unfunded
supplemental defined benefit pension plan in the United States to provide
retirement benefits in excess of levels allowed by the Employee Retirement
Income Security Act (ERISA). The actuarial present value of accumulated plan
benefits totaled $1.3 million and $1.1 million at December 31, 1994 and 1993,
respectively. Net pension expense was $0.4 million in 1994 and 1993.

H.  SAVINGS PLAN
 
     The Company sponsors a Savings Plan covering substantially all domestic
employees. Under this plan, employees may contribute up to 12% of their
compensation (subject to Internal Revenue Service limitations). The Company
annually matches employee contributions up to 6% of such compensation at rates
ranging from 50% to 100%. The Company's contributions vest after two years,
although contributions for those employees with five years of service vest
immediately.
 
     The trustees of the Savings Plan were granted an option to purchase 900,000
shares of the Company's common stock, exercisable at $9.50 per share (the fair
market value of the Company's common stock at the date of the grant) in five
cumulative annual installments beginning in 1990. In 1994, the trustees
exercised the remaining 265,000 shares. Under the terms of the Plan, any gains
realized from the sale of option shares are first allocated to participants'
accounts to fund up to one-half of the minimum Company contribution. Any excess
is applied to additional funding.
 
     In 1994, the Company established a Supplemental Savings Plan to provide
savings benefits in excess of those allowed by ERISA. The provisions of which
are the same as the Savings Plan.
 
     Under these plans, the amount charged to operations was $2.0 million in
1994, 1993 and 1992.

I.  EMPLOYEE STOCK PURCHASE PLAN
 
     Under the 1979 Stock Purchase Plan, employees are entitled to purchase
shares of common stock through payroll deductions of up to 10% of their
compensation. The price paid for the common stock is equal to 85% of the lower
of the fair market value of the Company's common stock on either the first or
last business day of the year. In January 1995, the Company issued 245,229
shares of common stock to employees who participated in the Plan during 1994 at
a price of $22.74 per share. During 1994, the Company amended the Plan to
increase the number of shares authorized thereunder by 400,000 shares. Currently
there are 560,640 shares reserved for issuance.
 
J.  STOCKHOLDER RIGHTS PLAN
 
     The Company's Board of Directors adopted a Stockholder Rights Plan on March
14, 1990, under which a dividend of one Common Stock Purchase Right was
distributed for each outstanding share of Common Stock. The Plan entitles Stock
Purchase Right holders to purchase shares of Company Common Stock for $40 per
share in certain events, such as a tender offer to acquire 30% or more of the
Company's outstanding shares. Under some circumstances, such as a determination
by Continuing Directors that an acquiring party's interests are adverse to those
of the Company, the Plan entitles such holders (other than an acquiring party or
adverse party) to purchase $80 worth of Common Stock (or other securities or
consideration owned by the Company) for $40. The Plan will expire March 26, 2000
unless earlier redeemed by the Company.

     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes." As
permitted by SFAS 109, the Company has elected not to restate its financial
statements for any periods prior to 1993. The effect on operations for 1993 was
immaterial. However, upon adoption of SFAS 109 the Company increased Additional
Paid-in Capital by $5.7 million relating to the tax benefits to be derived from
the utilization of U.S. net operating loss carryforward amounts resulting from
tax deductions pertaining to the issuance of the Company's stock to employees
under its benefit plans.
