ITEM 1.   BUSINESS

     Electro Scientific Industries, Inc. and its subsidiaries ("ESI" or "The 
Company") provides electronics manufacturers with equipment necessary to 
produce key components used in wireless telecommunications, computers, 
automotive electronics, and many other electronic products. ESI believes it 
is the leading supplier of advanced laser systems used to fine tune 
electronic circuitry, improve the yield of semiconductor memory devices, and 
of high-speed test and termination equipment used in the high-volume 
production of miniature capacitors. Additionally, ESI produces a family of 
mechanical and laser drilling systems for production of printed wiring boards 
and advanced electronic packaging, as well as machine vision products 
for manufacturers of semiconductors, electronics and other products. ESI's 
products enable these manufacturers to reduce production costs, increase 
yields and improve the quality of their products. ESI's customers include 
manufacturers of: wireless telecommunication and automotive electronics 
products (Ericsson, LG Semiconductor, Motorola, Siemens and WUS); miniature 
capacitors (KEMET, Kyocera/AVX, Philips, Samsung and TDK); semiconductor 
memory devices (Fujitsu, Hitachi, Hyundai, IBM, and Samsung); printed wiring 
boards (Samsung, Johnson-Matthey/ACI and WUS) and users of machine vision 
systems in electronic manufacturing equipment (Kulicke and Soffa, Universal 
Instruments, and Canon). 

ELECTRONICS INDUSTRY OVERVIEW

     The electronic content of telecommunications products, automobiles and 
personal computers continues to increase.  For example, automobile 
manufacturers now routinely include electronic ignition, anti-lock brakes, 
electronic fuel injection and other electronic systems in place of components 
that in the past were predominantly mechanical. In addition, markets for 
consumer-oriented electronic products such as cellular telephones, fax 
machines, pagers, camcorders and personal computers have developed rapidly as 
increasingly affordable products have been introduced. 

     Demand for electronics manufacturing equipment is driven by the demand 
for electronic devices and circuits. Electronic components are used in 
virtually all electronic products, from inexpensive consumer electronics to 
the most sophisticated computers. These components are produced in very large 
unit volumes. 

     The demands upon manufacturers to supply increasing quantities of 
electronic components have been accompanied by demands for increased 
complexity, reduced size and improved quality. As electronic products become 
more powerful and portable, the devices and circuits in these products must 
be faster, smaller and more reliable. To achieve these attributes of higher 
performance, electronic device manufacturers increase densities and tune 
the devices to precise electrical values. Manufacturers of cellular 
telephones, for example, must use miniaturized circuits to accommodate the 
size limitations of the finished product. These circuits must also operate 
within precise frequency specifications, typically requiring component values 
with less than 0.5 percent tolerance, enabling the existing cellular 
frequency bands to accommodate more cellular users without interchannel 
interference. 

     As electronic device densities and performance demands have increased, 
the manufacturers of capacitors and resistors have been compelled to reduce 
size and to improve performance of these individual components. The 
increasing miniaturization of these components makes production, testing and 
termination difficult.  ESI's leading-edge technologies provide our customers 
with the capability to address these challenges.


                                       3

     Another trend throughout the electronics industry is cost reduction. The 
highly competitive markets for electronic products create cost limitations at 
the consumer level, and result in cost pressure on component manufacturers. 
Manufacturers continuously seek to reduce device costs by improving throughput,
yield and quality in device production. 

OVERVIEW OF MARKETS, PRODUCTS AND STRATEGY

     Pagers, cellular telephones, personal computers and automotive 
electronics represent the largest end-market applications for electronic 
devices and circuits that are produced using ESI's systems. ESI's customers 
also serve a wide range of other electronic applications. 

     ESI believes it is critical that each of its products provide the 
customer with measurable production benefits including improved yield, 
increased throughput, greater reliability, and increased flexibility, 
resulting in a high return on investment. ESI designs its production systems 
with a migration path for system upgrade, providing customers the flexibility 
to add capacity or improve product performance at a reasonable incremental 
cost. 

     ESI designs and manufactures products which target several markets 
within the electronics industry. These products include circuit fine tuning 
systems, electronic component manufacturing equipment, memory yield improvement
systems, machine vision solutions and advanced electronic packaging equipment.

CIRCUIT FINE TUNING SYSTEMS.  ESI's circuit fine tuning systems precisely 
tune the frequency of electronic circuits that receive and transmit signals 
in pagers, cellular telephones and other wireless devices. ESI's laser 
trimming systems also tune automotive electronic assemblies such as engine 
control circuits. Customers include Analog Devices, Autecs, Burr-Brown, 
C-MAC, Ericsson, Motorola, Siemens, and TA-I.

     An application-specific laser adjusts the electrical performance of an 
electrical product or assembly containing many circuits by removing a precise 
amount of material from one or more components in the circuit.  This is done 
to achieve the desired electrical specification for the entire product.  This 
process is called "functional trimming," and is performed while the product 
or assembly is under power. For example, in pagers, laser trimming of a few 
selected components in the product is used to tune the product to the desired 
frequency.

ELECTRONIC COMPONENT MANUFACTURING EQUIPMENT.  ESI's product offerings in the 
electronic component market consist of automated test, production and 
handling equipment for manufacture of miniature multi-layer ceramic 
capacitors (MLCCs) which are used in very large numbers in nearly all types 
of electronic circuits. MLCCs are used in circuits that process analog 
signals or operate at high frequencies in products such as computers, video 
equipment, and voice and wireless telecommunication products. Customers 
include KEMET, Kyocera/AVX, Pan Overseas, Philips, Samsung, Siemens, Taiyo 
Yuden and TDK. 

     The worldwide miniature surface mount capacitor market is estimated to be
approximately $3.3 billion (300 billion units) in 1998. Most of the leading
producers are in Japan, led by Murata, TDK and Kyocera. Production demands
imposed by miniaturization are leading capacitor manufacturers to 


                                       4
<PAGE>

increasingly consider merchant equipment suppliers, such as ESI, as an 
alternative to internal development of manufacturing equipment.

     As circuit sizes have shrunk, the size of commonly used miniature 
capacitors has also shrunk as small as .02" x .01". These minute sizes, and 
the high unit volumes place extraordinary demands on manufacturers. ESI's 
products combine high-speed, small parts handling technology with 
microprocessor-based systems to provide highly automated solutions for MLCC 
manufacturers. 

     Virtually all capacitors are tested and sorted by capacitance 
(electrical energy storage) and dissipation factor (electrical energy 
leakage). ESI's equipment employs high-speed handling and positioning 
techniques to precisely load, test and sort capacitors based upon these 
electrical values. MLCCs are manufactured in a lamination process, which 
involves layering conductive and insulation materials. ESI's 
microprocessor-based termination systems apply conductive material to the 
ends of surface mountable MLCCs, permitting connection of the device in a 
circuit. ESI produces a fully automated product line for termination of MLCCs 
and capacitor arrays. ESI's component visual inspection system provides 
automated machine vision based inspection of MLCCs. Parts are inspected for 
dimensional inspection and defect detection.

     
MEMORY YIELD IMPROVEMENT SYSTEMS.  Nearly all manufacturers of dynamic random 
access memory (DRAM) use memory yield improvement systems to increase 
production yields. Personal computers and high performance workstations are 
the largest market for DRAM, though many consumer products, such as 
photocopiers, fax machines and telecommunications equipment require 
increasing amounts of memory. ESI's memory yield improvement system customers 
include Canon, Fujitsu, Hitachi, Hyundai, IBM, LG Semiconductor, NEC, 
Samsung, Siemens, and Acer.

     Memory device manufacturers use a laser process that removes defective 
circuit elements while programming spare elements to be replacements and 
thereby salvaging a memory device.  Cost reductions and demand for higher 
capacity memory devices have lead manufacturers to reduce the size of circuit 
elements while increasing the number of circuit elements per device.  This 
increased density in memory devices has resulted in lower primary 
manufacturing yields, increasing the need for advanced memory repair 
technology.

     The memory yield enhancement process begins with circuit designers 
adding extra (redundant) elements to the memory chip.  During the 
manufacturing process each device is tested.  When a defective element is 
identified, its location or address is recorded and given to ESI's memory 
yield improvement system to effect a replacement or repair.  The system 
positions a laser beam over connecting links of the defective element and 
cuts the electrical path. Design redundancy is used by every significant 
manufacturer of DRAMs and is increasingly being used by manufacturers of 
other semiconductor memory applications, such as static random access memory 
(SRAMs), digital signal processors (DSPs), and other logic devices with 
embedded memory.

     
VISION PRODUCTS.  ESI provides electronics manufacturers with machine vision 
solutions for automated process control and visual inspection for the 
assembly of computer chips, PWBs and discrete electronic components. ESI has 
concentrated its efforts on selling vision products to original equipment 
manufacturer (OEM) suppliers of semiconductor and electronics equipment.  
Customers for ESI's vision products include Canon, IBM, Kulicke and Soffa, 
Lucent Technologies, Motorola, Siemens and Universal Instruments.

                                       5

     Machine vision has emerged as a critical technology as semiconductor 
manufacturers move toward higher densities and more complex architectures. 
By allowing them to achieve greater precision, increased equipment speed, and 
fewer errors, machine vision pervades the integrated circuit (IC) 
manufacturing process from wafer production through packaging.

     ESI offers machine vision solutions with  low cost computer 
architecture, easy-to-use software development tools, powerful application 
software and advanced lighting and optics. These features reduce application 
development time and shorten time to market for producers of computer chips 
and PWBs.

ADVANCED ELECTRONIC PACKAGING SYSTEMS.  ESI provides a cost-effective method 
for forming vias, which are the basis for creating electrical connections 
between layers in multiple PWBs and electronic packages.  ESI's advanced 
electronic packaging customers include Adflex, Greatsino, Hadco, IBM, 
Johnson-Matthey/ACI, Nippon Mectron, Nitto Denko, Samsung, and WUS. 

     ESI uses laser drilling and mechanical drilling and routing technology 
to address applications in the IC packages, multi-chip modules, and 
high-density circuit boards.  The primary advantage of the technology is the 
ability to process very small vias in a wide variety of materials, including 
ceramic, traditional glass reinforced circuit boards, copper, and new organic 
compounds. ESI produces computer-controlled mechanical routers which cut and 
shape individual PWBs out of panels - as well as the larger holes and special 
cavities for mounting of semiconductor die.  ESI's mechanical and laser 
drills produce thousands of tiny holes for mounting components on a PWB.

SALES, MARKETING AND SERVICE

     ESI sells its products worldwide through direct sales and service 
offices located in or near: Ann Arbor, MI, Boston, MA, Portland, 
OR, and San Diego, CA in North America; Tokyo and Nagoya, Japan, Seoul, 
Korea, and Taipei, Taiwan in Asia; and Munich, Germany, London, England, 
Paris, France, and Leiderdorp, The Netherlands in Europe. ESI serves 
customers in approximately 30 additional countries through manufacturers' 
representatives. 

     ESI has a substantial base of installed products in use by leading 
worldwide electronics manufacturers. ESI emphasizes strong working 
relationships with these customers to meet their needs for additional systems 
and to facilitate the successful development and sale of new products to 
these customers. 

     ESI maintains service personnel wherever it has a significant installed 
base and provides service anywhere its equipment is installed. New systems 
are tested to ensure they meet requirements and acceptance criteria as 
specified by customers. ESI offers a variety of maintenance contracts and 
parts replacement programs. 

     Sales outside the U.S. accounted for 57.6%, 64.1% and 59.9% of ESI's net 
sales for fiscal 1998, 1997 and 1996.

     In fiscal 1998, 1997 and 1996, no customer exceeded 10% of sales.

BACKLOG

     Backlog consists of written purchase orders for products, spare parts and
service, which ESI expects to ship within twelve months. Backlog was $21.8
million at May 31, 1998 versus $31.8 million at May 31, 1997 and $45.6 million
at May 31, 1996.
 

RESEARCH, DEVELOPMENT AND TECHNOLOGY

     ESI believes that its ability to compete effectively depends, in part, on
its ability to maintain and expand its expertise in core technologies and
product applications. The primary emphasis of ESI's research and development is
to advance ESI's capabilities in: 

     -    Lasers and laser/material interaction 
     -    High speed, sub-micron motion control systems 
     -    Precision optics 
     -    High speed, small parts handling 
     -    Image processing and optical character recognition 
     -    Real-time production line electronic measurement 
     -    Real-time software 
     -    Systems integration 
     
     ESI's research and development expenditures for fiscal  1998, 1997, and 
1996 were $28.5 million (12.4% of net sales), $22.7 million (12.6% of net 
sales), and $21.5 million (11.4% of net sales), respectively. The foregoing 
figures do not include the effect of research and development expenditures 
funded by the Defense Advanced Research Projects Agency (DARPA) of the U.S. 
Government.

     Research and development expenditures for the years ended May 31, 1996 
and 1998 do not include the acquired in-process research and development 
expense incurred in connection with the purchase of XRL, Inc. ("XRL") and 
Dynamotion Corporation ("Dynamotion").

COMPETITION

     ESI's markets are competitive. The principal competitive factors in 
ESI's markets are product performance, reliability, service, technical 
support, product improvements, price, established relationships with 
customers and product familiarity.  ESI believes that its products compete 
favorably with respect to these factors. Some of ESI's competitors have 
greater financial, engineering and manufacturing resources larger service 
organizations than ESI. Some of these customers develop, or have the ability 
to develop, similar manufacturing equipment.  There can be no assurance that 
competition in ESI's markets will not intensify or that ESI's technological 
advantages may not be reduced or lost as a result of technological advances 
by competitors or customers or changes in electronic device processing 
technology. 

     Major competitors for circuit fine tuning systems include NEC and 
General Scanning. For electronic component manufacturing equipment, ESI's 
competition includes Tokyo Weld, Kanebo and Humo in Japan, as well as 
manufacturers that develop systems for internal use. ESI's major competitors 
for the Memory Yield Improvement are Nikon and General Scanning.  ESI 
competes with stand alone vision suppliers such as Cognex, Robotic Vision 
Systems and ICOS systems. There are also numerous other vision companies and 
captive vendors in Japan, North America and Europe.  ESI's Advanced 
Electronic Packaging systems compete with mechanical drills manufactured by 
companies such as Hitachi-Seiko, Excellon and Pluritec and laser systems 
providers, Lumonics, Sumitomo, Mitsubishi and Hitachi-Seiko. 

MANUFACTURING AND SUPPLY

     ESI's principal production facilities are located in Portland, Oregon. 
Portland's manufacturing operations consist of electronic subassembly, laser 
production and final system assembly for circuit fine tuning, memory yield 
improvement, component visual inspection and advanced electronic packaging 
systems. Electronic component systems are manufactured by ESI's subsidiaries, 
near San Diego, California.  The majority of ESI's vision systems are 
manufactured by ESI's subsidiary in Ann Arbor, Michigan.

     ESI uses qualified manufacturers to supply many components of its 
products. ESI's systems use high performance computers, peripherals, lasers 
and other components from various vendors.  Some components used by ESI are 
obtained from a single source or a limited group of suppliers. An 
interruption in the supply of a particular component could require 
substitutions that would have a temporary adverse impact on ESI. ESI believes 
it has good relationships with its suppliers.

EMPLOYEES

     As of May 31, 1998, ESI employed 900 people, including 238 in 
engineering, research and development, 334 in manufacturing and 328 in 
marketing, sales, technical support, customer service and administration.  
Many of ESI's employees are highly skilled, and ESI's success will depend in 
part upon its ability to attract and retain such employees, who are in great 
demand. ESI has never had a work stoppage or strike and no employees are 
represented by a labor union or covered by a collective bargaining agreement. 
ESI considers its employee relations to be good.

PATENTS AND OTHER INTELLECTUAL PROPERTY

     ESI has a policy of seeking patents, when appropriate, on inventions 
relating to new products and improvements which are discovered or developed 
as part of ESI's on-going research, development and manufacturing activities. 
ESI owns 78 United States patents and has applied for 23 additional patents 
in the United States. ESI has 69 foreign patents and has applied for 97 
additional foreign patents. Although ESI's patents are important, ESI 
believes that the success of its business depends to a greater degree on the 
technical competence and innovation of its employees. 

     ESI relies on copyright protection for its proprietary software. ESI 
also relies upon trade secret protection for its confidential and proprietary 
information. There can be no assurance that others will not independently 
develop substantially equivalent proprietary information and techniques, or 
that ESI can meaningfully protect its trade secrets. 
          
     Some customers using certain products from ESI have received a notice of 
infringement from Jerome H. Lemelson, alleging that equipment used in the 
manufacture of semiconductor products infringes on patents issued to Mr. 
Lemelson relating to "machine vision" or "barcode reader" technologies. 
Certain of these customers have notified ESI that they may be seeking 
indemnification from ESI for any damages and expenses resulting from this 
matter. Some of ESI's customers have settled litigation with Mr. Lemelson. 
While ESI cannot predict the outcome of this or similar litigation or its 
effect upon ESI, ESI believes that it will not have a materially adverse 
effect on its financial condition or results of operations.

ITEM 2.   PROPERTIES

     The Company's executive and administrative offices as well as a 
manufacturing facility are located in a three-building complex located on 15 
acres in Portland, Oregon. The buildings are owned by ESI, and contain 
approximately 205,000 square feet of floor space.  ESI also owns a 64,000 
square foot plant on ten acres of land in Escondido, California.

     In addition, the Company leases approximately 13,000 square feet of 
office and industrial space in Portland, Oregon; 15,000 square feet of 
industrial space in Canton, Massachusetts; 8,000 square feet of office and 
industrial space in San Marcos, California; 30,000 square feet of office and 
industrial space in Santa Ana, California; 35,000 square feet of office and 
industrial space in Ann Arbor, Michigan; and office and service space in 
several additional locations in the United States, and in seven foreign 
countries. 

     The Company believes that the productive capacity of the aforementioned 
facilities to be adequate and suitable for the requirements of the business. 

ITEM 3.   LEGAL PROCEEDINGS

     On December 26, 1996, ESI filed a lawsuit against General Scanning, Inc. 
in the United States District Court for the Northern District of California 
for patent infringement.  The complaint alleges that General Scanning is 
infringing two of ESI's patents used in the Model 9300 laser repair systems 
(patent numbers 5,265,114, "System and Method for Selectively Laser 
Processing a Target Structure of One of More Materials of a Multimaterial, 
Multilayer Device," and 5,473,624, "Laser System and Method for Selectively 
Severing Links").  ESI is seeking damages and an injunction against further 
infringement.  General Scanning has filed counterclaims alleging that certain 
ESI patents are invalid and unenforceable and that ESI has interfered with 
General Scanning's business reputation. General Scanning is seeking damages 
and declaratory judgments that the ESI patents are not infringed, are invalid 
and are unenforceable. No trial date has been set. 

     While ESI cannot predict the outcome of this litigation or its effect 
upon ESI, the Company believes that it will not have a material adverse 
effect on its financial condition or the results of its operations.

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

     The Company completed three mergers in fiscal 1998 including the
acquisition of AISI on December 1, 1997, Chip Star on June 26, 1997, and
Dynamotion on June 9, 1997.  The AISI and Chip Star acquisitions were accounted
for under the pooling-of-interests method, and the Dynamotion acquisition was
accounted for as a purchase. Refer to the Notes to Consolidated Financial
Statements for additional information.

FISCAL YEAR ENDED MAY 31, 1998 COMPARED TO FISCAL YEAR ENDED MAY 31, 1997

     Revenue for fiscal 1998 was $229.6 million, which was 27.5% or $49.6
million higher than for fiscal 1997.  The increase was due to higher sales of
advanced electronic packaging systems, electronic component equipment and
machine vision systems. The three mergers discussed above added both product and
selling capabilities to the Company's portfolio.  

     Gross margin for the year ended May 31, 1998 was 54.4%, up from 53.4% in
the prior fiscal year. Increased shipments of relatively high margin electronic
component systems and machine vision equipment, both in total and as a
percentage of total sales, contributed to the overall increase.

     Selling, service and administrative expenses were $13.8 million or 31.8%
higher for the year ended May 31, 1998 as compared to fiscal 1997.   The
increase is attributable to higher commission expenses associated with
increased sales, higher recruiting and relocation costs and increased legal fees
associated with on-going litigation.  Selling, service and administrative
expenses increased marginally as a percentage of sales from 24.1% to 24.9%.

     Research, development and engineering expenses for the year ended May 
31, 1998 were $5.8 million higher than the prior year due to higher project 
expenses and an increased commitment to research. Research, development and 
engineering expenses declined slightly as a percentage of sales, to 12.4% for 
1998 from 12.6% for the prior year. In connection with the purchase price 
allocation for Dynamotion, the Company estimated the fair value of the 
intangible assets which indicated that a majority of all of the acquired 
intangible assets consisted of research and development projects in process.  
At that time, the development of these projects had not reached technological 
feasibility and the technology was believed to have no alternative future 
use.  In accordance with generally accepted accounting principles, the 
acquired in-process research and development of $9.0 million has been 
reflected in merger related expenses in the accompanying financial 
statements.  The Company currently believes that the research and development 
efforts will result in commercially feasible products in the next 18 months 
at an additional estimated cost of  $1.5 million.

     The effective tax rate of 37.1% for the year ended May 31, 1998 was
consistent with fiscal 1997.  The benefit of the utilization of net operating
losses was offset by non-deductible merger-related expenses.

     Net income for the year ended May 31, 1998 was $16.9 million or $1.52 per
basic share compared to $19.5 million or $1.85 per basic share for the same
period of the prior year.  Fiscal 1998 net income includes merger-related
expenses of $14.6 million, including $9.0 million for acquired in-process
research and development and $5.6 million for professional service fees and
expenses associated with consolidating operations.  Excluding merger-related
expenses, fiscal 1998 net income was $27.8 million or $2.50 per basic share.


                                       14
<PAGE>

FISCAL YEAR ENDED MAY 31, 1997 COMPARED TO FISCAL YEAR ENDED MAY 31, 1996

     Revenue for fiscal 1997 was $180.0 million, which was 5.0% or $9.4 million
lower than for fiscal 1996.  The decline was due to lower shipments of capacitor
production equipment during the first half of fiscal 1997, due to customers
absorbing capacity added in the prior year, and lower sales of circuit fine
tuning systems throughout the year.  These declines were partially offset by an
increase from $4.8 million to $10.8 million in laser-based advanced electronic
packaging systems and smaller increases in the sales of memory yield improvement
and vision systems.

     Gross margin of 53.4% for the year ended May 31, 1997 was slightly below
the 54.6% gross margin for fiscal 1996. Increased manufacturing overhead cost
per unit sold was the most significant factor causing the decrease in margin.
Increased sales of higher margin memory yield improvement systems and advanced
electronic packaging equipment positively affected gross margin.

     Selling, service and administrative expenses were $2.9 million lower for
the year ended May 31, 1997 versus fiscal 1996.  The decrease is a result of
lower selling commissions associated with decreased sales volumes and lower
incentive compensation.  Selling, service and administrative expenses decreased,
as a percentage of sales, to 24.1% from 24.4%. 

     Research, development and engineering expenses for the year ended May 31,
1997 were $1.2 million higher than the prior year.  Research, development and
engineering expenses increased, as a percentage of sales, to 12.6% for 1997 from
11.4% for the prior year.

     The effective tax rate of 37.1% for the year ended May 31, 1997 increased
from 32.2% as a result of benefits from U.S. tax losses during the year ended
May 31, 1996.

     Net income for the year ended May 31, 1997 was $19.5 million or $1.85 per
basic share compared to $20.4 million or $1.96 per basic share for the same
period of the prior year.

     The acquired in-process research and development expense if $6.0 million,
which occurred in connection with the purchase price allocation of XRL, was
expensed during the first quarter of fiscal 1996 in accordance with generally
accepted accounting principals.  ESI estimated the fair market value of the
intangible assets, indicating that a majority of the acquired intangible assets
consisted of research and development in process.

FINANCIAL CONDITION AND LIQUIDITY
                                          
     The Company's principal sources of liquidity are existing cash, cash
equivalents and marketable debt securities of $38.9 million, accounts receivable
of $61.9 million, and a $7.0 million line of credit, none of which was
outstanding at May 31, 1998.  ESI has no debt and a current ratio of 9.3:1. 
Working capital increased to $141.8 million at May 31, 1998, from $121.5 million
at May 31, 1997.  

     The Company may acquire or invest in other complementary businesses,
product lines or technologies.  These acquisitions or investments may require
additional debt or equity capital to fund such activities. However, capital
expenditures for the fiscal 1999 are expected to decrease approximately 50% over
the level incurred during the past year due to the high volume of renovations
and the acquisition of a building that occurred during fiscal 1998.

(2) Total cash and securities decreased from $48.2 million on May 31, 1997 to
$38.9 million on May 31, 1998.  


OPERATING ACTIVITIES: Operating activities provided $5.1 million in cash. 
This was mainly due to net income and the effect of non-cash merger related 
expenses offset by cash used in trade receivables, inventory purchases, and 
for the pay down of current liabilities. Trade receivables increased $6.9 
million due to longer payment terms granted in conjunction with entry into 
new Asian markets for our advanced electronic packaging equipment. Collection 
of receivables in June 1998 reduced this balance by approximately $3.2 
million. The increase in inventories was primarily due to increased levels of 
inventories needed to support the increase in the Company's sales, 
particularly those related to the three merged businesses. This increase in 
sales activity resulted in a corresponding increase in inventory.  The 
decrease in current liabilities of $13.1 million is a function of the 
liquidation of substantial past due balances for the acquired Dynamotion 
subsidiary as well as an acceleration of income tax payments.

INVESTING ACTIVITIES: Net cash of $17.1 million was used in investing 
activities.  The Company made purchases in the amount of $12.5 million to 
upgrade computing and manufacturing capabilities and to renovate and improve 
utilization of office and manufacturing space. Associated with this was the 
purchase of a third building in Portland to accommodate future manufacturing 
and office space needs. In addition, net purchases of highly liquid 
marketable debt securities utilized $1.3 million. 

FINANCING ACTIVITIES: Net cash of  $1.5 million was generated from financing 
activities in the form of  $8.5 million in stock option exercises and the 
related tax benefit, partially offset by the liquidation of acquired 
Dynamotion debt of $7.0 million.

FACTORS THAT MAY AFFECT FUTURE RESULTS

     The Company's business depends in large part upon the capital 
expenditures of manufacturers of electronic devices, including miniature 
capacitors, semiconductor memory devices and circuits used in wireless 
telecommunications equipment, including pagers and cellular phones, 
automotive electronics and computers. The markets for products manufactured 
by the Company's customers are cyclical and have historically experienced 
periodic downturns, which often have had a negative effect on the demand for 
capital equipment such as that sold by the Company. Ten large multinational 
electronics companies constituted 41.4% of the Company's fiscal 1998 sales 
and therefore, the loss of any of these customers would be significant.

     The market for the Company's products is characterized by rapidly 
changing technology and evolving industry standards. The Company believes 
that its future success will depend on its ability to develop and manufacture 
new products and product enhancements and to introduce them successfully into 
the market. Failure to do so in a timely fashion could harm the Company's 
competitive position. The announcements or introductions of new products by 
the Company or its competitors may adversely affect the Company's operating 
results, since these announcements may cause customers to defer or forego 
ordering products from the Company's existing product lines.

     International shipments accounted for 57.6% of sales for fiscal 1998 
compared to 64.1% of sales for fiscal 1997. The Company expects that 
international shipments will continue to represent a significant percentage 
of net sales in the future. In the Asia/Pacific region, sharp slowdowns have 
occurred in many countries.  In response to declines in their currencies, 
many governments have raised interest rates, cut spending, and begun 
restructuring their economies. The short-term effect is likely to be slower 
growth in Japan, China and the Asia/Pacific region.  As a result, a 
significant portion of the Company's net sales will be subject to certain 
risks.  These risks include changes in demand resulting from fluctuations in 
interest and currency exchange rates, as well as factors such as government 
financed competition, changes in trade policies, tariff regulations, 
difficulties in obtaining US export licenses and the difficulties of staffing 
and managing foreign operations.  At May 31, 1998, substantially all Asian 
end customer receivables were secured by letters of credit.

     Most of the Company's sales are transacted in dollars and the Company's 
products are made in the United States. Many Japanese customers pay in yen; 
therefore, ESI hedges these sales transactions to mitigate currency risks. 
The European and Asian sales subsidiaries' operating expenses are denominated 
in their respective local currencies. These transactions represent 
approximately 9.1% of fiscal 1998 consolidated operating expenses and are 
split 60% and 40% respectively between Europe and Asia. Changes in the value 
of the local currency, as measured in US dollars, will commensurably increase 
or decrease operating expenses.

     ESI believes that it has the product offerings and resources needed for 
continuing success; however, future revenue and margin trends cannot be 
reliably predicted and may cause the Company to adjust its operations. 
Factors external to the Company can result in volatility of the Company's 
common stock price. Because of the foregoing factors, recent trends should 
not be considered reliable indicators of future stock prices or financial 
results.

YEAR 2000


                                       17
<PAGE>

     The Year 2000 (Y2K) issue is the result of computer programs operating 
incorrectly when the calendar year changes to January 1, 2000.  Any of the 
Company's computer programs that have date-sensitive software may recognize a 
two-digit date using "00" as calendar year 1900 rather than the year 2000.  
This could result in system failure or miscalculations causing disruptions of 
operations, including, among other things, a temporary inability to engage in 
normal business activities.

The Company has a task force to prepare for Y2K issues.  The Company has 
evaluated its technology and data used in the creation and delivery of its 
products and services and in its internal operations and has identified Y2K 
issues related to its customers and suppliers. The core business systems ESI 
uses and all major products are compliant, or a migration path to a compliant 
version will be in place by the year 2000.  A plan has been put in place to 
mitigate the risks associated with these issues for ESI suppliers and 
customers, but there can be no assurances that such third parties will 
successfully address their own Y2K issues over which the company has no 
control. The Company believes that it will substantially complete the 
implementation of its Y2K plan before the year 2000, and provided that third 
parties mitigate their own risks successfully, the Company believes it will 
have no material business risk from such Y2K issues.  ESI believes that the 
total costs associated with addressing the Y2K issue will have an immaterial 
affect on the Company's financial statements.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       (IN THOUSANDS, EXCEPT PER SHARE DATA)

BUSINESS ENVIRONMENT

     The accompanying consolidated financial statements include the accounts of
Electro Scientific Industries, Inc. and its subsidiaries (the Company), all of
which are wholly owned.  The Company designs and manufactures sophisticated
products used around the world in electronics manufacturing including: laser
manufacturing systems for memory yield improvement, production and test
equipment for the manufacture of surface mount ceramic capacitors, circuit fine
tuning systems, precision laser and mechanical advanced electronic packaging
production systems and machine vision systems.  The Company serves the global
electronics market from its headquarters in Portland, Oregon and through
subsidiaries located in the United States, Europe and Asia.

CONCENTRATIONS OF CREDIT RISK

     The Company uses financial instruments that potentially subject it to
concentrations of credit risk. Such instruments include cash equivalents,
securities held for sale, trade receivables and financial instruments used in
hedging activities.  The Company invests its cash in cash deposits, money market
funds, commercial paper, certificates of deposit and readily marketable debt
securities.  The Company places its investments with high credit quality
financial institutions and limits the credit exposure from any one institution
or instrument.  To date, the Company has not experienced losses on any of these
investments.  The Company sells a significant portion of its products to a small
number of electronics manufacturers: 41.4% of fiscal 1998 revenues were derived
from ten customers.  The Company's operating results could be adversely affected
if the financial condition and operations of these key customers decline.

CONCENTRATIONS OF OTHER RISKS

     The Company's operations involve a number of other risks and uncertainties
including but not limited to the cyclicality of the electronics market, rapidly
changing technology, international operations and hedging exposures.  Refer to
Management's Discussion and Analysis for additional commentary.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     All material intercompany accounts and transactions have been eliminated.


                                       24

BASIS OF PRESENTATION

     In June, 1997, ESI merged with Chip Star, Inc. (Chip Star), a 
privately-held company based in San Marcos, California.  Chip Star produces 
capital equipment for producers of surface mount ceramic capacitors.  
Consideration paid to Chip Star was 700 shares of ESI stock.  The merger was 
accounted for as a pooling-of-interests.  Accordingly, all financial 
statements and footnote data have been restated. 

     In December 1997, ESI merged with AISI, a privately-held company based 
in Ann Arbor, Michigan.  AISI provides machine vision solutions for the 
semiconductor and electronics industries. Consideration paid to AISI was 
1,400 shares of ESI stock, of which 1,126 have been issued and the remaining 
have been reserved for stock options assumed in the acquisition.  The merger 
was accounted for as a pooling-of-interests. Accordingly, all financial 
statements and footnote data have been restated.  

USE OF ESTIMATES

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

RECLASSIFICATIONS

     Certain reclassifications have been made in the accompanying 
consolidated financial statements for 1996 and 1997 to conform to the 1998 
presentation.

REVENUE RECOGNITION

     The Company generally recognizes revenue at the time of shipment. 

PRODUCT WARRANTY

     The Company generally warrants its systems for a period of up to 12 
months for material and labor to repair and service the system.  A provision 
for the estimated cost related to warranty is recorded upon shipment.

RESEARCH AND DEVELOPMENT

     Research and development costs are expensed as incurred. 

TAXES ON INCOME

     Deferred income taxes have not been provided on unremitted earnings of 
foreign subsidiaries as the Company believes any U.S. tax on such earnings 
would be substantially offset by associated foreign tax credits.


                                       25
<PAGE>

NET INCOME PER SHARE

     The Company adopted Statement of Financial Accounting Standards No. 128, 
"Earnings Per Share," (SFAS 128).  SFAS 128 requires the dual presentation of 
basic and diluted earnings per share and other additional disclosures. Basic 
earnings per share are computed by dividing net income by the weighted 
average number of common shares outstanding. Diluted earnings per common 
share are computed by dividing net income by the weighted average number of 
common shares and common share equivalents (stock options) outstanding. Prior 
year earnings per share have been restated to conform to the standards 
established by SFAS 128.

CASH EQUIVALENTS

     The Company considers all highly liquid investments with a maturity of 
three months or less at date of purchase to be cash equivalents. 

INVENTORIES

     Inventories are principally valued at standard costs, which approximate 
the lower of cost (first-in, first-out) or market. Costs utilized for 
inventory valuation purposes include material, labor and manufacturing 
overhead. 

DEPRECIATION AND CAPITALIZATION POLICIES

     Depreciation is determined on the declining balance and straight-line 
methods based on the following useful lives: buildings: 25 to 40 years; 
building improvements: 5 to 15 years; and machinery and equipment: 3 to 10 
years. 

     Expenditures for maintenance, repairs and minor improvements are charged 
to expense. Major improvements and additions are capitalized. When property 
is sold or retired, the cost and related accumulated depreciation are removed 
from the accounts and the resulting gain or loss is included in other 
expense. 

FOREIGN CURRENCY TRANSLATION

     The total cumulative translation adjustment included in retained 
earnings is $(1,144), $(4) and $429 at May 31, 1998, 1997 and 1996, 
respectively. Foreign currency transaction gains were $48 and  $380 for the 
years ended May 31, 1998 and 1996, with a loss of $176 for the year ended May 
31, 1997. These amounts are included in other expense in the accompanying 
Consolidated Statements of Income.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" (SFAS130).  This statement will be effective for the Company's year
ending May 31, 1999.  The statement establishes presentation and disclosure
requirements for reporting comprehensive income. Comprehensive income includes
charges or credits to equity that are not the result of transactions with
shareholders. The Company expects there will be no material impact on its
consolidated financial position or results of operations as a result of the
adoption of this new accounting standard.  


PROPERTY AND EQUIPMENT

     Major classes of property and equipment consist of the following:

LINE OF CREDIT

     The Company has a short-term revolving line of credit with a large 
foreign bank totaling $7,000. This line expires in September 1998.  
Management expects to renew the revolver under similar terms or secure 
alternate financing.  At the Company's option, the interest rate is prime or 
LIBOR plus 1.25 percent. There were no borrowings outstanding under the line 
at anytime during fiscal 1998.
     
EMPLOYEE BENEFIT PLANS

     The Company has an employee savings plan under the provisions of section 
401(k) of the Internal Revenue Code. The Company contributed $763, $406 and 
$462 to the plan for the years ended May 31, 1998, 1997 and 1996, 
respectively. 

INCOME TAXES

     Deferred tax assets and liabilities are determined based on the 
temporary differences between the financial statement and tax bases of assets 
and liabilities as measured by the enacted tax rates for the years in which 
the taxes are expected to be paid.

     The net deferred tax asset as of May 31, 1998 and May 31, 1997 consists 
of the following tax effects relating to temporary differences and 
carryforwards:

</TABLE>

     At May 31, 1998, there were net operating losses of $26,353 available 
for U.S. federal income tax purposes.  These losses were principally acquired 
as part of the Dynamotion and AISI acquisitions and expire through 2013. 
These losses are subject to certain limitations caused by the change in 
ownership. Accordingly, their utilization in future periods may be severely 
restricted. Given these limitations and uncertainties regarding future 
profitability, some of these losses may not be realizable, and accordingly, a 
valuation allowance has been recorded.

EARNINGS PER SHARE

     The Company adopted Statement of Financial Accounting Standards No.128, 
"Earnings Per Share" (SFAS 128), in the third fiscal quarter of 1998.  Under 
the provisions of SFAS 128, primary earnings per share has been replaced by 
basic earnings per share, which does not include the dilutive effect of stock 
options in its calculation.  In addition, fully diluted earnings per share 
has been replaced by diluted earnings per share.  All prior period earnings 
per share amounts have been restated to reflect the requirements of SFAS 128. 
 Basic earnings per share has been computed using the weighted average number 
of common shares outstanding during the period.  Diluted earnings per share 
has been computed using the weighted average number of common shares and 
equivalents (representing the dilutive effect of stock options) outstanding 
during the period.  No adjustments to net income were required for any period 
presented for purposes of presenting basic and diluted earnings per share.  
All earnings per share amounts in the following table are presented and, 
where necessary, restated to conform to the SFAS 128 requirements.

COMMITMENTS AND CONTINGENCIES

     The Company has limited involvement with derivative financial instruments
and does not use them for trading purposes.  Derivatives are used to manage well
defined foreign currency risks:  the Company enters into forward exchange
contracts to hedge the value of accounts receivable denominated in a foreign
currency.  Foreign exchange contracts have gains and losses that are recognized
at the settlement date.  At May 31, 1998 and 1997, the Company had forward
exchange contracts totaling $5,319 and $5,470, respectively.  These contracts
generally mature in less than one year and the counterparty is a large, widely
recognized international bank; therefore, risk of credit loss as a result of
nonperformance by the bank is minimal.  The use of derivatives does not have a
significant effect on the Company's results of operations or its financial
position.

     The Company leases equipment and office space under operating leases, which
are non-cancelable and expire on various dates through 2002.  The aggregate
minimum commitment for rentals under operating leases beyond May 31, 1998 is not
significant.

     The Company is a party to various legal proceedings. Management believes
that the outcome of such proceedings will not have a material effect on the
business, financial position or results of operations of the Company.

SECURITIES AVAILABLE FOR SALE

     The Company classifies its marketable debt securities as Securities
Available for Sale in the accompanying Consolidated Balance Sheets. The fair
market value of these securities at May 31, 1998 and 1997 is $29,113 and
$27,860, respectively.  All of the Company's marketable debt securities are
invested in high-credit quality tax advantaged securities, with maturities of
less than one year from the date of purchase. The amortized cost of these
securities approximates fair market value.

     During fiscal 1998 and 1997, proceeds of $17,415 and $32,800, respectively,
resulted from the sales or maturities of securities; there were no realized
gains or losses associated with these sales or maturities.

SHAREHOLDER RIGHTS PLAN

     In May 1989, the Company adopted a Shareholder Rights Plan and declared a
dividend distribution of one Right for each outstanding share of Common Stock,
payable to holders of record on June 23, 1989. Under certain conditions, each
Right may be exercised to purchase 1/100 of a share of Series A No Par Preferred
Stock at a purchase price of $55, subject to adjustment. The Rights are not
presently exercisable and will only become exercisable following the occurrence
of certain specified events. If these specified events occur, each Right will be
adjusted to entitle its holder to receive, upon exercise, Common Stock (or, in
certain circumstances, other assets of the Company) having a value equal to two
times the exercise price of the Right or each Right will be adjusted to entitle
its holder to receive, upon exercise, common stock of the acquiring company
having a value equal to two times the exercise price of the Right, depending on
the circumstances. The Rights expire on May 12, 1999 and may be redeemed by the
Company for $0.01 per Right. The Rights do not have voting or dividend rights,
and until they become exercisable, have no dilutive effect on the earnings of
the Company.

STOCK PLANS

     The Company has stock option and restricted stock grant plans for officers
and employees. During fiscal 1998, ESI recorded $455 and $475 of compensation
expense related to stock grants earned in 1998 and 1997, respectively.  The
Company incurred no such compensation expense in fiscal 1996.  The Compensation
Committee of the Board of Directors determines awards under these plans. Stock
appreciation rights may be granted in connection with options, although no
options have been granted that include stock appreciation rights. Option prices
are at fair market value at the date of the grant and all expire ten years from
the date of grant. 

     The Company has an employee stock purchase plan which allows qualified
employees to direct up to 15% of base pay for purchases of stock. The purchase
price for shares purchased under the Plan is 85% of the fair market value of
stock on January 8, 1998 or January 7, 1999.

     The Company accounts for its stock option plans and its employee stock
purchase plan in accordance with the provisions of the Accounting Principles
Board's Opinion No. 25 (APB 25), "Accounting For Stock Issued to Employees."  In
1995, the Financial Accounting Standards Board released Statement of Financial
Accounting Standard No. 123 (SFAS 123), "Accounting For Stock Based
Compensation."  SFAS 123 provides an alternative to APB 25 and was effective
beginning with the Company's 1996 fiscal year.  The Company will continue to
account for its employee stock plans in accordance with the provisions of APB
25.  Accordingly, the Company has elected to provide pro forma disclosures as
required by SFAS 123.


                                       32
<PAGE>

     The Company has computed, for pro forma disclosure purposes, the per share
value of all options granted under the stock option plan to be $17.88, $14.16
and $11.99 for 1998, 1997 and 1996.  The pro forma value of options granted
under the employee stock purchase plan is immaterial for 1998, 1997 and 1996. 
These computations were made using the Black-Scholes option-pricing model, as
prescribed by SFAS 123, with the following weighted average assumptions for
grants in 1998, 1997, and 1996:

<TABLE>
<CAPTION>
                              1998            1997           1996
<S>                         <C>            <C>            <C>
Risk-free interest rate        7.5%           7.5%           7.5%
Expected dividend yield          0%              0              0
Expected life               5 years        7 years        7 years
Expected volatility           46.5%          48.5%          48.5%
</TABLE>

     The total value of options granted would be amortized on a pro rata basis
over the vesting period of the options. Options generally vest equally over four
years.  If the Company had accounted for these plans in accordance with SFAS
123, the Company's net income and net income per share would have decreased as
reflected in the following pro forma amounts:

ACQUISITIONS

CHIP STAR, INC.

On June 26, 1997, the Company completed the acquisition of Chip Star Inc., a 
provider of ceramic capacitor termination systems located in San Marcos, 
California, through the issuance of 700 shares of ESI stock. The transaction 
has been accounted for as a pooling of interests and, accordingly, all data 
included in the Consolidated Financial Statements has been restated to 
reflect the Chip Star acquisition. Disclosure of ESI and Chip Star's revenue 
and net income, on an individual company basis from June 1 to June 25, 1997 
is not significant.

APPLIED INTELLIGENT SYSTEMS, INC. (AISI)

On December 1, 1997, the Company completed the acquisition of AISI, a 
provider of machine vision solutions for the semiconductor and electronics 
industries, located in Ann Arbor, Michigan.  The acquisition consideration 
consists of 1,400 shares of ESI common stock, of which 1,126 have been issued 
and the remaining 274 were reserved for stock options assumed in the 
acquisition.  The transaction has been accounted for as a 
pooling-of-interests and, accordingly, all data included in the Consolidated 
Financial Statements has been restated. 

The following is a reconciliation of certain restated amounts with amounts 
previously reported.  Chip Star operations from the period June 1, 1997 to 
the date of acquisition were immaterial and as such were combined in ESI 
activity for the fiscal year 1998.  AISI activity shown for fiscal 1998 is 
for the period from June to December 1, 1997, the date of acquisition.

DYNAMOTION CORP.

On June 9 1997, the Company acquired all of the outstanding stock of 
Dynamotion Corp., a producer of high performance mechanical drilling and 
routing systems based in Santa Ana, California. The preliminary purchase 
consideration consisted of 347 shares of ESI stock.  The transaction was 
accounted for as a purchase. In connection with the purchase price 
allocation, the Company estimated the fair value of the intangible assets 
indicating that a majority of the acquired intangible assets consisted of 
research and development projects in process.  At that time, the development 
of these projects had not reached technological feasibility and the 
technology was believed to have no alternative future use. In accordance with 
generally accepted accounting principles, the acquired in-process research 
and development of $9.0 million has been reflected in merger-related expenses 
in the accompanying financial statements. 

     Pro forma combined income statement data for the year ended 1998 is equal 
to consolidated income statement figures for the year as the activity of 
Dynamotion from June 1, 1997 to the date of acquisition was insignificant.  
Pro forma combined income statement data for the years ended May 31, 1997 
and 1996 are as follows:

                      REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of
Electro Scientific Industries, Inc.:

     We have audited the accompanying consolidated balance sheets of Electro 
Scientific Industries, Inc. (an Oregon corporation) and subsidiaries as of 
May 31, 1998 and 1997, and the related consolidated statements of income, 
shareholders' equity and cash flows for each of the three years in the period 
ended May 31, 1998.  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 financial statements referred to above present 
fairly, in all material respects, the financial position of Electro 
Scientific Industries, Inc. and subsidiaries as of May 31, 1998 and 1997, and 
the results of their operations and their cash flows for each of the three 
years in the period ended May 31, 1998 in conformity with generally accepted 
accounting principles.
