ITEM 1.  BUSINESS
 
GENERAL
 
     MEMC Electronic Materials, Inc. (MEMC or the Company) is a leading
worldwide producer of silicon wafers. The silicon wafer is the fundamental
building block from which almost all semiconductors are manufactured.
Semiconductors are used in virtually all electronic applications, including
computers, telecommunications equipment, automobiles, consumer electronics
products, industrial automation and control systems, and analytical and defense
systems. We operate manufacturing facilities, directly or through joint
ventures, in Italy, Japan, Malaysia, South Korea, Taiwan, and the United States.
We sell silicon wafers to most of the world's largest manufacturers of
semiconductors. We are the leading worldwide supplier of silicon wafers outside
of Japan and the only significant non-Japanese silicon wafer manufacturer with
manufacturing and research facilities in Japan.
 
     MEMC was incorporated in 1984 under the name Dynamit Nobel Silicon
Holdings, Inc. (DNS). Huls AG, a subsidiary of VEBA AG, subsequently acquired
ownership of DNS. In 1989, Huls AG, through DNS and other related companies,
acquired the electronic materials businesses operated by Monsanto Company
(Monsanto) in the United States, Europe, Japan and Malaysia. Huls AG changed the
name of DNS to MEMC Electronic Materials, Inc. and combined the assets acquired
from Monsanto with the assets of its United States and Italian silicon wafer
business to form the current MEMC. VEBA Corporation, a subsidiary of VEBA AG,
acquired all of the outstanding common stock of MEMC from Huls AG in 1990, which
it subsequently transferred to its wholly-owned subsidiary, Huls Corporation, in
1993. On July 12, 1995, the Company completed its initial public stock offering.
As a result of the public stock offering, Huls Corporation's ownership interest
in the Company was reduced to 51.9%. On September 30, 1998, Huls Corporation
merged into VEBA Corporation.
 
     On October 22, 1998, we filed a registration statement with the Securities
and Exchange Commission (the "SEC") for the sale of our common stock in a rights
offering to existing stockholders except VEBA AG and its affiliates (the
"Offering"). We expect to sell approximately 13,628,446 shares in the Offering.
On March 22, 1999, we sold 15,399,130 shares of common stock to VEBA Zweite
Verwaltungsgesellschaft mbH ("VEBA Zweite"), a subsidiary of VEBA AG, in a
private placement. VEBA Zweite has also agreed to purchase all shares of common
stock issuable upon exercise of the rights that are not subscribed for by other
stockholders in the Offering, subject to certain conditions that are customary
in a firm commitment underwriting.
 
     We are engaged in one reportable industry segment -- the design,
manufacture and sale of electronic grade silicon wafers for the semiconductor
industry. Financial information regarding this industry segment is contained in
our 1998 Annual Report which information is incorporated herein by reference.
 
INDUSTRY OVERVIEW
 
     Almost all semiconductors are manufactured from silicon wafers, and thus
the strength of the silicon wafer industry is highly correlated to the
performance of the semiconductor industry. Although there are over two hundred
semiconductor manufacturers worldwide, we believe that the top twenty
semiconductor manufacturers accounted for over 70% of all semiconductor revenues
in 1998. We also believe that of the approximately 18 silicon wafer
manufacturers in the world today, six principal manufacturers, including MEMC,
supply a substantial majority of the wafers used by the major semiconductor
manufacturers.
 
  Semiconductor Industry
 
     The semiconductor industry historically has been a high growth cyclical
industry. Worldwide, the industry grew at a compound annual growth rate of 14.1%
from $24.3 billion in revenues in 1985 to $134.8 billion in revenues in 1998,
according to Dataquest estimates. Continuous improvements in semiconductor
process and design technologies, semiconductor fabrication equipment and the
composition of silicon wafers
 
                                        1
<PAGE>   3
 
have allowed semiconductor manufacturers to produce more complex, higher
performance and more reliable devices at a lower cost per device. The result has
been a large proliferation of uses for semiconductors and historically rapid
growth in semiconductor revenue.
 
     Despite the semiconductor industry's history of significant growth,
semiconductor revenues grew by only 3.6% in 1997 and declined by 8.4% in 1998,
according to Dataquest estimates. This slowdown has been attributed to excess
capacity and resultant price erosion, especially for DRAM (commonly used
computer memory chips). This downturn extended through 1998 due to continued
overcapacity and the weak economic conditions in the Asia Pacific and Japanese
markets.
 
     Throughout this downturn, semiconductor manufacturers have been exerting
significant price pressure on their raw material suppliers, including silicon
wafer manufacturers. Semiconductor manufacturers have also accelerated the speed
at which they have reduced their device line widths, or the distance between
circuit elements, in an effort to reduce costs. The reduction in line widths
results in a requirement of less silicon per device. Additionally, the
semiconductor industry has recently experienced significant restructuring and
consolidation activities.
 
     Semiconductor manufacturers greatly reduced their capital spending
beginning in late 1997 and throughout 1998. This reduced capital spending has
limited additions to capacity.
 
  Silicon Wafer Industry
 
     The silicon wafer industry historically has been a high growth cyclical
industry correlated to the growth of the semiconductor industry. Worldwide, the
industry grew at a compound annual growth rate of 9.2% from 1.2 billion square
inches in 1985 to 3.7 billion square inches in 1998, according to Dataquest
estimates. From 1993 through the first half of 1996 the industry was
characterized by excess demand and wafer shortages. Due to these shortages and
anticipated future demand, wafer manufacturers quickly added capacity,
especially for 8-inch wafers, the predominant wafer used in the industry today
and the wafer diameter anticipated to have the most significant growth in demand
over the next several years. This growth rate declined significantly in 1996.
 
     The silicon wafer industry slowdown, which began in the summer of 1996, has
left the industry in a state of overcapacity. Price declines have resulted from
this overcapacity. Moreover, the weakness of the Japanese yen and Deutsche mark
have allowed Japanese and German competitors to offer lower dollar based
pricing. The price declines have been greatest for 8-inch wafers where the
highest overcapacity exists. According to Dataquest, silicon wafer consumption
declined by an estimated 7.6% in 1998.
 
     Major silicon wafer manufacturers, including MEMC, invested in 12-inch
wafer manufacturing capacity in anticipation that the semiconductor industry
would migrate to this larger diameter wafer. However, in 1998, the industry
experienced a softening semiconductor market and successful implementation of
thinner device linewidths on the current diameters. This resulted in industry
recognition that the transition to 12-inch wafers would be delayed. The new
transition timing requires 12-inch wafer characteristics to be even more
advanced at the time they are introduced for production of integrated circuits.
 
     The leading semiconductor manufacturers organized and funded two industry
consortia, International Sematech in Austin, Texas, and SELETE in Japan, for the
purpose of evaluating 12-inch equipment and materials. While the primary use of
12-inch wafers in 1999 will continue to be for semiconductor device process and
tool development, MEMC expects to also ship samples of 12-inch prime polished
and epitaxial wafers.
 
PRODUCTS
 
     Our silicon wafers vary in diameter, surface features (polished or
epitaxial), composition, electrical properties and method of manufacture. Our
silicon wafers are manufactured according to the exacting specifications
required by the our customers; we currently produce wafers with a variety of
product features satisfying more than 1,000 unique product specifications.
Semiconductor manufacturers require wafers of
 
                                        2
<PAGE>   4
 
larger diameter and more stringent technical specifications in order to produce
increasingly complex semiconductor devices such as the larger megabit memory
chips and microprocessors.
 
     Our customers have increased their focus on efficient semiconductor
production processes because their manufacturing processes for semiconductor
devices have become more expensive. Our customers make many semiconductor
devices, or chips, from the same wafer, and all chips from a particular wafer
are manufactured and processed simultaneously at each stage in the device
manufacturing process. Because of this, larger-sized wafers allow for a greater
throughput from the same semiconductor manufacturing process and allow
semiconductor manufacturers to spread their fixed costs of production over a
larger volume of finished products. For example, a 6-inch (150 millimeter) wafer
has a surface area of approximately 27.4 square inches, whereas an 8-inch (200
millimeter) wafer has a surface area of approximately 48.7 square inches. Thus,
the 8-inch wafer has approximately 78% more surface area than the 6-inch wafer.
A 12-inch (300 millimeter) wafer has a surface area of approximately 109.6
square inches or approximately 125% more surface area than an 8-inch wafer.
Despite the industry's focus on 6-inch and larger diameter wafers, we continue
to manufacture and sell a significant amount of 4-inch (100 millimeter) and
5-inch (125 millimeter) wafers.
 
     We manufacture wafers in sizes ranging from 4 inches to 8 inches in
diameter as well as a limited number of 12-inch diameter wafers from our pilot
development lines. Customers use the larger diameter wafers in more
sophisticated applications where semiconductor manufacturers benefit from the
increased efficiencies and greater number of available die per wafer.
 
     Our silicon wafers fall into one of three general types:
 
  Prime Polished Wafers
 
     Our principal product is the prime polished wafer, which is a highly
refined, pure silicon wafer with an ultraflat and ultraclean surface. We put
prime polished wafers through a sophisticated chemical-mechanical polishing
process that removes defects and leaves an extremely smooth surface. This makes
the wafers suitable for the advanced technologies used by our customers. Our
customers use prime polished wafers in a broad range of applications for
integrated circuit devices.
 
  Epitaxial Wafers
 
     Customers have forced semiconductor manufacturers to use smaller and
smaller device features in order to incorporate more complex functionality in
the integrated circuit. Smaller devices also improve performance and control
power consumption and heat production. We manufacture epitaxial wafers to serve
the technological demands of our customers that manufacture advanced
semiconductors.
 
     Epitaxial wafers consist of a thin, single-crystal silicon layer grown on
the polished surface of the silicon wafer. The wafer is designed to have
different composition and electrical properties from the epitaxial layer on the
wafer surface. The wafer, among other things, helps to improve isolation between
circuit elements our customers fabricate on the silicon film surface of the
wafer. One result of such smaller devices is the requirement that the distance
between circuit elements becomes increasingly narrow. The industry refers to the
distance between circuit elements as line widths. A critical aspect in the
construction of any integrated circuit device is the isolation of these
different elements that comprise the integrated circuit device. Without
sufficient isolation of the various elements, the elements could communicate
electrically with each other, which could ruin the device. Epitaxial wafers
provide improved isolation and allow for increased reliability of the finished
semiconductor device, greater efficiencies during the semiconductor
manufacturing process, and ultimately more complex integrated circuit devices.
 
  Test/Monitor Wafers
 
     We supply test/monitor wafers, or monitor wafers, to our customers for
their use in testing semiconductor fabrication lines and processes. Although
monitor wafers are substantially the same as prime polished wafers with respect
to cleanliness, and in some cases flatness, other specifications are generally
less rigorous. This
 
                                        3
<PAGE>   5
 
allows us to produce monitor wafers from the portion of a silicon ingot that
does not meet customer specifications for wafers to be used in the manufacture
of semiconductors. Therefore, sales of monitor wafers allow us to experience a
higher yield from each silicon ingot produced.
 
RAW MATERIALS
 
     The main raw material in our production process is polysilicon. We produce
over one-half of our total polysilicon requirements and purchase the remainder
of our requirements from others. The availability of polysilicon currently
significantly exceeds demand. We believe that an adequate supply of polysilicon
will be available internally or from others for the foreseeable future.
 
     We obtain substantially all of our requirements for several raw materials,
equipment, parts and supplies from sole suppliers. Although we believe that we
could find adequate alternative sources of supply for these raw materials,
equipment, parts and supplies, we may be required to obtain new qualifications
from our customers in order to change or substitute suppliers. Because we cannot
predict whether we would be successful or how long that process would take, our
manufacturing yields could be adversely affected while we transition to a new
supplier.
 
     We believe that adequate quantities of all our key raw materials,
equipment, parts and supplies are currently available. However, because of the
cyclical nature of our industry, we may experience shortages in the future. See
"Business -- Risk Factors -- We Depend on Certain Suppliers and Finding
Alternative Sources of Supply Could Affect Adversely Our Customer Qualifications
and Manufacturing Yields."
 
MANUFACTURING PROCESS
 
     Silicon wafers for the semiconductor industry are extremely complex
materials with characteristics such as high purity levels, highly uniform
crystal structure, and precise mechanical tolerances. Electronic grade silicon
is one of the most refined materials in the world, having an impurity level of
no more than one part per billion. Requirements for highly uniform crystal
structure, mechanical tolerances and cleanliness in the manufacture of silicon
wafers are at levels that stretch manufacturing processes to the limits of
measurement, and necessitate that we conduct certain processes in "clean rooms."
 
     The silicon wafer manufacturing process consists of three principal phases:
the crystal growth process, the wafer slicing process and the wafer finishing
process.
 
  Crystal Growth Process
 
     The first step in the wafer manufacturing process is the formation of a
large, silicon single crystal or ingot. This process begins with the melting of
polysilicon, together with minute amounts of electrically active elements such
as arsenic, boron, phosphorous or antimony in a quartz crucible.
 
     Once the melt has reached the desired temperature, we lower a silicon seed
crystal, or "seed" into the melt. The melt is slowly cooled to the required
temperature, and crystal growth begins around the seed. As the growth continues,
the seed is slowly extracted or "pulled" from the melt. The temperature of the
melt and the speed of extraction govern the diameter of the ingot, and the
concentration of an electrically active element in the melt governs the
electrical properties of the silicon wafers to be made from the ingot. This is a
complex, proprietary process requiring many control features on the
crystal-growing equipment.
 
  Wafer Slicing Process
 
     After we grow the ingots, we extract them from the crystal pulling furnaces
and allow them to cool. We grind the ingots to the specified diameter, and then
we slice the ingots into thin wafers. Next, we prepare the wafers for the
surface polishing steps with a multi-step process using precision lapping
machines, edge contour machines and chemical etchers.
 
                                        4
<PAGE>   6
 
  Wafer Finishing Process
 
     Final polishing and cleaning processes give the wafers the clean and
superflat mirror polished surfaces required for the fabrication of semiconductor
devices. For wafer polishing, we currently use our proprietary, ninth-generation
polishers together with an innovative chemical-mechanical polishing process.
This form of polishing was one of our early inventions that first allowed solid
state devices to move from individual circuits to the complexities of today's
integrated circuits. We further process some of our products into epitaxial
wafers.
 
RESEARCH AND DEVELOPMENT
 
     A number of factors drive our current research and development efforts.
These include our business strategy and focus mainly on:
 
     - the development and improvement of large diameter and advanced silicon
       wafer products;
 
     - manufacturing process improvements; and
 
     - enhancement and cost reduction of existing products.
 
     Customer focus also influences research and development. We work closely
with customers in developing new products and refining existing products to
faster meet the needs of the marketplace. To strengthen this relationship and
interaction, we assign research and development application engineers to key
customer accounts worldwide.
 
     A recent product innovation of our research and development program
includes a new class of polished wafer with a virtually defect-free wafer
surface. We are currently delivering 6-inch and 8-inch diameters of this class
of polished wafer to customers for evaluation in increasing their yields. We
also engage in ongoing research and development to continuously improve the
surface of epitaxial wafers. Further, as a result of our commitment to develop
the next diameter of silicon wafers, we are now supplying high quality 12-inch
wafers to the industry from pilot development lines. We first produced our
12-inch diameter wafers in 1991 and believe we are one of the industry leaders
in the development of this next generation of wafers. Our new class of polished
wafer and 12-inch wafers are in the pilot stage of development, and we cannot
assure you that either will ever mature to a commercial product.
 
     We continue to see rapid technological change and product innovation in the
market for silicon wafer products. In response to this business environment, we
recently commissioned a "Wafering Center of Excellence" to direct our wafering
process research and development. The Wafering Center of Excellence is located
at our plant in Utsunomiya, Japan and has the capacity to produce 12-inch
wafers.
 
     We do not expect the demand for 12-inch wafers to develop until the year
2001 or beyond. In the interim, we expect semiconductor customers to continue
their support of two industry consortia to develop the tool set and processes
necessary to fabricate integrated circuits on 12-inch wafers.
 
     Our expenditures for research and development activities during 1998, 1997
and 1996, excluding expenditures by our unconsolidated joint ventures, were
$81.6 million, $64.5 million and $44.3 million, respectively, representing
10.8%, 6.5% and 4.0% of our net sales for the respective periods.
 
MARKETING AND SALES
 
     We market most of our products through a direct sales force. We believe a
key element of our marketing strategy is establishing and maintaining close
relationships with our customers. We try to accomplish this through
multi-functional teams of technical, marketing and sales, and manufacturing
personnel. These teams work closely with customers in developing their new
production facilities, qualifying our products for use at such new facilities
and maintaining qualification at all existing manufacturing facilities. We
complete sales principally through indicative-only contracts of one year or less
that indicate expected volumes and specify price.
 
                                        5
<PAGE>   7
 
     Our close relationships with our customers are partly the result of the
lengthy and expensive "qualification" process by which customers qualify silicon
wafer manufacturers, and their individual facilities, to supply a particular
product. We are aware of changing customer needs and target our manufacturing to
try to produce wafers adapted to each customer's process and requirements. For
1998, the following ten customers generated over half of our sales:
 
     - Advanced Micro Devices, Inc.;
 
     - Chartered Semiconductor Manufacturing, Ltd.;
 
     - Cypress Semiconductor Corporation;
 
     - International Business Machines Corporation;
 
     - Motorola, Inc.;
 
     - National Semiconductor Corporation;
 
     - Philips Electronics N.V.;
 
     - Samsung Electronics Co., Ltd.;
 
     - ST Microelectronics N.V.; and
 
     - Texas Instruments Incorporated.
 
Texas Instruments alone represented approximately 20%, 20% and 17% of our sales
in 1998, 1997 and 1996, respectively.
 
COST REDUCTION PLAN
 
     During the first half of 1998 we accelerated our cost reduction plan in
response to the difficult industry environment.
 
     We decided to close our small-diameter wafer facility in Spartanburg, South
Carolina and to withdraw from our joint venture participation in a
small-diameter wafer facility in China. We are negotiating the terms of our
withdrawal with our joint venture partner. We took these actions because:
 
     - our customers have been operating their 8-inch fabrication lines in
       preference to their smaller diameter fabrication lines, reducing the
       demand for smaller diameter wafers;
 
     - a number of our customers recently have undertaken restructuring
       initiatives focused on permanently eliminating small diameter lines; and
 
     - we believe that even when the semiconductor market begins to recover, we
       will have excess small diameter wafer capacity.
 
     We also decided not to construct a new 8-inch wafer facility in Malaysia
due to the substantial excess capacity for these wafers.
 
     In addition, we implemented a voluntary separation program for our hourly
and salaried U.S. employees. As a result of the actions described above and
other initiatives, we are reducing our workforce by approximately 2,000
employees, or 25% compared to December 31, 1997.
 
     We estimated pre-tax savings from our restructuring activities and our
voluntary separation program to be $60 million on an annualized basis. We began
to realize approximately $30 million of these estimated savings in the third
quarter of 1998 through reduced personnel costs as a result of the voluntary
separation program.
 
     We expect the other $30 million in annualized savings to come from the
closure of our Spartanburg facility. We expect approximately half of the savings
from the Spartanburg facility's closure to relate to personnel costs, and the
other half of these savings to relate to manufacturing costs such as
depreciation and supplies and utilities. As we re-qualify and transfer the
production of silicon wafers made at the Spartanburg facility to other
locations, we expect to reduce our Spartanburg workforce. With each workforce
reduction, we
 
                                        6
<PAGE>   8
 
expect a portion of our annualized cost savings associated with personnel costs
to be realized. As a result, we began to realize a portion of the remaining $30
million in annualized cost savings in the third quarter of 1998. As the
manufacturing cost savings are fixed in nature, we expect they will largely be
realized upon the closure of the Spartanburg facility.
 
     The time frame for achieving the $30 million in annualized cost savings
from the closing of the Spartanburg facility is largely dependent upon how long
it takes us to re-qualify the silicon wafers produced at the Spartanburg
facility at our other locations. This, in turn, determines how quickly
Spartanburg's workforce will be reduced. While we believe that this will occur
during the second quarter of 1999, the ability to re-qualify silicon wafers is
highly dependent upon the cooperation of our customers.
 
     We are also implementing a number of other cost cutting and savings
initiatives:
 
     - We have initiated short-term plant shutdowns to better align production
       with the current lower level of demand;
 
     - We are accelerating the implementation of our "best practices" worldwide
       and the development of new manufacturing technologies in order to reduce
       our processing costs;
 
     - We are implementing a plant focus program that limits the number of wafer
       diameters manufactured at each site;
 
     - We have implemented aggressive spending cuts for all of our departments;
 
     - We are obtaining price concessions from our vendors; and
 
     - We are performing a critical review of our capital spending and research
       and development requirements and reducing these planned investments where
       possible.
 
     We anticipate that we will reduce our capital expenditures in 1999 to less
than $85 million.
 
     The statements above regarding expected future savings and cost reduction
efforts are forward-looking statements. Actual results could differ materially
from our expectations due to, among other things, the factors set forth above
and the accuracy of assumptions regarding savings from restructuring activities.
See "Cautionary Statement Regarding Forward-Looking Statements" and "Risk
Factors."
 
COMPETITION
 
     We face intense competition in the silicon wafer industry from established
manufacturers throughout the world. We believe that we possess certain
technological and other strengths relative to our competitors. However,
realizing and maintaining such strengths requires us to continue making a high
level of investment in research and development, marketing and customer service
and support. Our inability to maintain such investments could have a material
adverse effect on our operating results. For other risks related to competition,
see "Business -- Risk Factors -- We Experience Intense Competition in the
Silicon Wafer Industry and Our Customers Expect Continuing Technological
Innovation at a Low Cost" and "Business -- Risk Factors -- Currency Exchange
Rates and Increased Competition Have Reduced Wafer Prices and Have Led to Lower
Margins and Profits."
 
JOINT VENTURES
 
     We have entered into a number of joint ventures as part of our strategy to
leverage our capital, to enter expanding markets, to forge closer working
relationships with our principal customers and to broaden the geographic
diversification of our operations. We have unconsolidated joint ventures with
prominent partners in South Korea and Taiwan.
 
  POSCO HULS Co., Ltd.
 
     In 1990, we entered into a joint venture in South Korea with Samsung
Electronic Co., Ltd. and Pohang Iron and Steel. Samsung is a South Korean
manufacturer of integrated circuits and one of our largest
 
                                        7
<PAGE>   9
 
customers. Pohang is a South Korean steel manufacturer. The South Korea joint
venture is named POSCO HULS Co., Ltd. (commonly known as PHC) and manufactures
and sells silicon wafers in South Korea. PHC generated sales of $121.0 million
in 1998, $215.9 million in 1997 and $275.1 million in 1996. Over half of PHC's
sales in each of these years were to Samsung. PHC has the capacity to produce
per month an aggregate of approximately 320,000 6-inch and 8-inch wafers. We
currently own 40% of PHC. Pohang currently owns 40% and Samsung currently owns
20%.
 
     We have agreed to provide technical assistance and information to PHC. We
have also granted licenses to PHC to use certain technology to manufacture,
promote and sell silicon wafers. In exchange for such technical assistance and
licenses, we receive royalties. Through September 30, 1998, we received
quarterly royalties based on PHC's net sales. Effective October 1, 1998, the
agreement by which we provide technical assistance and information and have
granted licenses to PHC was amended. The amendment, among other things, extends
the term of the technical agreement. Under the amendment, we receive quarterly
royalties based on net sales and an annual royalty based on net income after
taxes. The quarterly royalties and the annual royalty we receive from PHC are
separate and independent calculations. Accordingly, if PHC has a net loss for
the fiscal year, then we will not receive an annual royalty based on net income
after taxes, but we will receive and retain the full amount of the quarterly
royalties based on net sales.
 
  Taisil Electronic Materials Corporation
 
     In 1994, we formed Taisil Electronic Materials Corporation with China Steel
Corporation. China Steel Corporation is a Taiwanese steel manufacturer. Taisil
manufactures and sells silicon wafers in Taiwan. Taisil generated sales of $58.7
million in 1998, $61.6 million in 1997 and $7.2 million in 1996. Taisil has the
capacity to produce approximately 140,000 8-inch wafers per month. Taisil has in
place infrastructure that could support the production of approximately 240,000
8-inch wafers per month. We currently own 45% of Taisil. The remainder of Taisil
is owned by China Steel Corporation (35%), Chao Tung Bank (10%) and the China
Development Corporation (10%).
 
     We have agreed to provide technical assistance and information to Taisil.
We have also granted licenses to Taisil to use certain technology to manufacture
and sell silicon wafers. In exchange for such technical assistance and licenses,
we receive semiannual royalties based on Taisil's net sales and operating
income.
 
     Taisil's financial performance has been adversely affected in recent
periods due to the downturn in the semiconductor industry in Taiwan. As a result
of this downturn, Taisil has incurred losses, which have negatively impacted its
debt-to-equity ratio. The increase in the debt-to-equity ratio and the downturn
in the semiconductor industry in Taiwan have raised concerns with Taisil's
lenders. In recent months, several financial institutions have indicated that
they would no longer purchase Taisil's commercial paper. Thus, Taisil was forced
to use alternative financing. In addition, we believe that several lenders have
placed Taisil on their credit watch lists. Certain of these lenders have also
made inquiries to MEMC and VEBA AG regarding our continued financial support to
Taisil. We have also been informed by one member of a three bank syndicate of
lenders to Taisil, that another bank in the syndicate expressed a preliminary
concern that a material adverse change in the financial condition of Taisil
might have occurred and, without additional equity contributions, an event of
default should be declared. Action by such bank syndicate, however, required the
agreement of two of the three banks, and we have been informed by the two other
banks that they did not believe a material adverse change in the financial
condition of Taisil had occurred.
 
     In order to improve Taisil's debt-to-equity ratio, certain of Taisil's
shareholders made capital contributions to Taisil of approximately $20.7 million
in November 1998 and $10.0 million in December 1998. Our share of these capital
contributions was approximately $10.3 million and $5.1 million, respectively. We
and certain of Taisil's other shareholders made an additional capital
contribution to Taisil of approximately $24 million in March 1999. Our share of
this capital contribution was approximately $12 million. Taisil also is in the
process of raising up to approximately $6 million of additional capital through
sale of stock to Taisil's employees and possibly to other investors. We believe
that these capital contributions will satisfy the concerns of Taisil's current
lenders, including the bank syndicate member that had previously expressed
concern about potential material adverse changes in the condition of Taisil.
However, if Taisil's financial performance
 
                                        8
<PAGE>   10
 
continues to be adversely affected by the downturn in the semiconductor industry
in Taiwan, we and Taisil's other shareholders may have to consider additional
financing alternatives for Taisil.
 
     Statements above as to future capital contributions to Taisil and the
response to such capital contributions by Taisil's lenders are forward looking
statements. Such future capital contributions and response from Taisil's lenders
may not occur due to a variety of factors, including inability of Taisil's
shareholders to agree on the magnitude, apportionment or other terms of such
capital contributions, changes or perceived changes in Taisil's prospects,
regulatory requirements and the willingness of Taisil employees to make an
equity investment in Taisil.
 
     For other information regarding Taisil, see "Business -- Risk Factors -- We
May Have to Make Substantial Payments in Connection With Our Taisil Joint
Venture, and This Could Divert Funds From Other Needed Areas."
 
OPTION ON PASADENA FACILITY
 
     In September 1998, we granted Tokuyama Corporation, Marubeni Corporation
and Marubeni America Corporation an option to acquire a majority interest in
MEMC Pasadena, Inc. Tokuyama is a Japanese polysilicon manufacturer and Marubeni
is a Japanese trading company. MEMC Pasadena is our granular polysilicon
subsidiary. In exchange for the option, Tokuyama and Marubeni made an option
payment to us. The term of the option is two years, subject to a one year
extension at the option of Tokuyama and Marubeni. If Tokuyama and Marubeni
exercise their option, we will then negotiate the terms and conditions
(including price) of the exercise with them based on the market value at that
time. The entire option payment will be applied toward the ultimate purchase
price. If Tokuyama and Marubeni do not exercise their option, then we will
return one-half of the option payment to them. During the term of the option,
Tokuyama and Marubeni have a right of first refusal over any transfer of MEMC
Pasadena's granular polysilicon business. In addition, for two years, we cannot
solicit offers from third parties for this business. In connection with the
option, Tokuyama will provide technical assistance to MEMC Pasadena for two
years (unless the option is earlier terminated by Tokuyama and Marubeni) to help
improve the quality of MEMC Pasadena's granular polysilicon products.
 
PROPRIETARY INFORMATION AND INTELLECTUAL PROPERTY
 
     As of November 30, 1998, we owned of record or beneficially approximately
112 U.S. patents, of which approximately 14 will expire by 2003, approximately
22 will expire between 2004 and 2008 and approximately 76 will expire after
2008. As of November 30, 1998, we owned of record or beneficially approximately
174 foreign patents, of which approximately 34 will expire by 2003,
approximately 79 will expire between 2004 and 2008 and approximately 61 will
expire after 2008. These foreign patents are generally counterparts of our U.S.
patents. We cannot assure you, however, that any of these patents will not be
challenged, invalidated or circumvented in the future, or that they do or will
provide a competitive advantage. As of that date, we have also submitted
approximately 96 U.S. and 440 foreign patent applications. However, we cannot
assure you that any of these applications will be granted.
 
     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy or otherwise obtain and use our products or technology that
we consider proprietary, and third parties may attempt to develop similar
technology independently. In addition, effective protection of intellectual
property rights may be unavailable or limited in certain countries. Accordingly,
there can be no assurance that our means of protecting our proprietary rights
will be adequate or that our competitors will not independently develop similar
technology.
 
     Under certain contracts, we are required to indemnify some third parties
against claims of infringement of the intellectual property rights of others.
 
     Any litigation in the future to enforce patents issued to us, to protect
trade secrets or know-how possessed by us or to defend us or indemnify others
against claimed infringement of the rights of others could have a material
adverse effect on our financial condition and operating results. Also,
regardless of the validity or
 
                                        9
<PAGE>   11
 
successful outcome of such claims, we may need to expend significant time and
expense to protect our intellectual property rights or to defend against claims
of infringement by third parties, which could have a material adverse effect on
us. If we lose any such litigation, the Company may be required to:
 
     - pay substantial damages;
 
     - seek licenses from others; or
 
     - change, or stop manufacturing or selling, some of our products.
 
     Any of these outcomes could have a material adverse effect on our business,
results of operations or financial condition.
 
EMPLOYEES
 
     At January 31, 1999, we had approximately 6,000 full-time employees and 100
temporary workers worldwide. We intend to close our Spartanburg, South Carolina
facility in the first half of 1999 and withdraw from our joint venture in
Luoyang, China during the second quarter of 1999. As of January 31, 1999,
approximately 530 full-time employees worked at our Spartanburg, South Carolina
facility and joint venture in Luoyang, China.
 
     We have not experienced any material work stoppages at any of our
facilities during the last several years. We believe our relationships with
employees are satisfactory.
 
GEOGRAPHIC INFORMATION
 
     Information regarding our foreign and domestic operations is contained in
Note 17 on page 42 of our 1998 Annual Report, which information is incorporated
herein by reference.
 
RISK FACTORS
 
     This Annual Report on Form 10-K contains "forward-looking" statements
within the meaning of the Securities Litigation Reform Act of 1995, including
those set forth under "Item 1. Business"; "Item 2. Properties"; and "Item 3.
Legal Proceedings." In addition to the business risks and uncertainties
discussed elsewhere in this Annual Report on Form 10-K, the following are
important risk factors which could cause actual results and events to differ
materially from those contained in any forward-looking statement contained
herein or made elsewhere by us.
 
  We Have Had Significant Operating and Net Losses and We Anticipate Future
  Losses
 
     We have not reported an operating profit since the third quarter of 1997.
We reported an operating loss in 1997 of $10.4 million. In 1998, we had an
operating loss of $333.3 million, which included restructuring costs of $146.3
million. Due to overcapacity and decreasing prices in the semiconductor and
silicon wafer industries, weak economic conditions in the Asia Pacific region
and Japan, and other factors, we do not expect to be profitable at least through
1999. We cannot predict how long we will continue to experience significant or
increasing operating and net losses or whether we will become profitable.
 
 We Need Substantial Capital Investments to Fund Our Future Operations Otherwise
 We May Not Keep Pace With Our Competitors
 
     We will need substantial amounts of cash to continue to fund capital
expenditures, research and development, and marketing and customer service and
support to keep pace with our competitors. Our business is very capital
intensive. Our capital needs depend on numerous factors, including our
profitability and investment in research and development and capital
expenditures. We cannot assure you that, even with the proceeds from our pending
rights offering, our recently completed private placement to VEBA Zweite and
cash flows from operations, if any, we will have enough capital to be able to
fund our future operations. We have incurred negative cash flows from operations
in recent periods.
 
                                       10
<PAGE>   12
 
 We May Not Be Able to Obtain Capital from Other Parties in the Future to Meet
 Our Needs and May Be Forced to Reduce Our Investment In Our Business
 
     We cannot assure you that we will be able to obtain capital in the future
to meet our needs. If we cannot obtain additional funding, whether from current
or new lenders or investors, we may be required to reduce our investments in
research and development, marketing and customer service and support and capital
expenditures. Such reductions could materially adversely affect our ability to
compete and our business.
 
     If we do find a source of additional capital, the terms and pricing of any
such financing may be significantly more favorable to the lender or investor
than those previously provided by us. Future capital raising could dilute or
otherwise materially adversely affect the holdings or rights of our existing
stockholders.
 
     Historically, we have funded our operations primarily through loans from
VEBA AG and its affiliates, internally generated funds and our initial public
offering. To a lesser extent, we have raised funds by borrowing money from
commercial banks. Recently, as part of our financial restructuring, we completed
a private placement of common stock to VEBA Zweite and are in the process of a
rights offering to our existing shareholders. The Company will continue to
explore and, as appropriate, enter into discussions with other parties regarding
possible future sources of capital. However, under the loan agreements between
us and our principal lender, VEBA AG and its affiliates, we cannot pledge any of
our assets to secure additional financing. We do not believe that we currently
can obtain unsecured financing from third parties on better terms than those
with VEBA AG and its affiliates.
 
 We Have Relied on VEBA AG and its Affiliates for Capital Funding in the Past,
 But May Not be Able to Rely on Them for Such Funding in the Future Which May
 Force Us to Reduce Expenditures
 
     VEBA AG and its affiliates are not obligated to provide capital to us
except in under the standby agreement entered into in connection with the
Company's pending rights offering and under current loan agreements. We cannot
assure you that VEBA AG and its affiliates will provide additional capital to us
in the future. We may be forced to reduce expenditures if VEBA AG and its
affiliates do not provide us with capital in the future. In such an event, we
may not be able to fund certain capital expenditures, research and development,
and marketing and customer service and support.
 
 We Have a Significant Amount of Debt That Will Adversely Affect Our Ability to
 Obtain Additional Financing
 
     The Company currently has a significant amount of debt that will adversely
affect our ability to obtain additional financing for working capital, capital
expenditures or other purposes. As of January 31, 1999, we owed $777.0 million
to VEBA AG and its affiliates, and $163.0 million to other lenders. Our debt
service could make us more vulnerable to industry downturns and competitive
pressures. In addition, the cash flow required to service our debt may reduce
our ability to fund internal growth and capital requirements.
 
 If The Semiconductor Industry Downturn Continues We Will Face Intense Pressure
 to Further Reduce Prices Which May Lead to Further Losses
 
     If the current downturn in the semiconductor industry continues, or the
industry experiences other downturns in the future, we will face pressure to
further reduce prices. However, our ability to reduce expenses during a downturn
is limited because of the fixed costs associated with our substantial excess
capacity and continued investment in research and development and marketing
necessary to maintain our extensive worldwide customer service and support
capabilities. If we are unable to reduce our expenses sufficiently to offset the
decline in our prices, our operating results and financial condition could be
materially adversely affected.
 
                                       11
<PAGE>   13
 
     Our business depends in large part upon the market demand for our
customers' semiconductors and products utilizing semiconductors. The
semiconductor industry experiences:
 
     - rapid technological change;
 
     - product obsolescence;
 
     - price erosion; and
 
     - wide fluctuations in product supply and demand.
 
     Recently, the semiconductor industry rapidly expanded its production
capacity, resulting in overcapacity, especially for DRAM (commonly used computer
memory chips). This overcapacity has caused semiconductor prices to decline,
which has depressed semiconductor revenues and profitability.
 
     From time to time the semiconductor industry has experienced significant
downturns and is currently in the midst of such a downturn. These downturns
often occur in connection with, or in anticipation of, maturing product cycles
(of both the semiconductor companies and their "end customers") and declines in
general economic conditions. Some of these downturns have lasted for more than a
year. Also, during such periods, customers of semiconductor manufacturers
benefiting from shorter lead times may delay some purchases of semiconductors
into future periods. The current semiconductor industry downturn began in the
fourth quarter of 1995. The resulting downturn in the silicon wafer industry
began in the summer of 1996.
 
     The economic recessions in Japan and in nations in the Asia Pacific region
have made the current downturn in the semiconductor industry worse. The
economies in these regions have contracted, and demand for semiconductors and
silicon wafers in these regions has decreased significantly.
 
  Substantial Excess Capacity and Declining Wafer Prices Limit Our Ability to
  Become Profitable
 
     Excess capacity in the silicon wafer industry limits our ability to
maintain or raise prices and could dramatically increase the worldwide supply of
silicon wafers in the future, increase the downward pressure on prices and
materially adversely impact our operating results. The growth in the worldwide
supply of silicon wafers has outpaced the growth in worldwide demand in recent
periods, especially for 8-inch silicon wafers. As a result, the selling prices
for our products have decreased. Because of price decreases and declining
product volume, our revenues are currently insufficient to offset our costs, and
this is adversely affecting our operating results. We have no firm information
with which to determine the capacity and expansion plans of our competitors.
Although some of our competitors have announced plans to slow their capacity
expansion programs, many have already added significant capacity for the
production of 8-inch wafers. We and our competitors have the ability to increase
production of silicon wafers through unused capacity and our ability to expand
our capacity quickly.
 
 Our Dependence on the Semiconductor Industry Causes Substantial Fluctuations in
 Our Operating Results and at Times This Has Adversely Affected the Market Price
 of MEMC Common Stock
 
     Our quarterly and annual operating results can fluctuate dramatically, and
this can adversely affect the market price of MEMC common stock. The main factor
affecting these fluctuations is our dependence on the performance of the
semiconductor industry, which historically has been cyclical. Another factor is
currency exchange rate volatility, which affects the price we receive for our
wafers and may result in gains or losses on unhedged currency exposure at our
unconsolidated joint ventures.
 
     Our operating results are also affected by:
 
     - the timing of orders from major customers;
 
     - product mix;
 
     - competitive pricing pressures; and
 
     - the delay between the incurrence of expenses to develop marketing and
       service capabilities and expand capacity and the realization of benefits
       from these expenditures.
 
                                       12
<PAGE>   14
 
     Moreover, customers may cancel or reschedule shipments, and production
difficulties could delay shipments. We cannot predict the future impact of any
of these factors. These and other factors could have a material adverse effect
on our quarterly or annual operating results.
 
  VEBA AG's Control of MEMC Could Prevent a Favorable Acquisition of MEMC
 
     VEBA AG's control of MEMC could prevent or discourage any unsolicited
acquisition of MEMC and consequently could prevent an acquisition favorable to
MEMC's other stockholders. After the pending rights offering, VEBA AG will
continue to have sufficient voting power to control our direction and policies.
VEBA AG will continue to be able to control any merger, consolidation or sale of
all or substantially all of our assets, to elect the members of the Board of
Directors and to prevent or cause a change in control of MEMC. Four of the eight
members of our Board of Directors are employees of VEBA AG or its affiliates,
not including MEMC.
 
     In addition, VEBA Corporation and VEBA Zweite (collectively, the VEBA
group) have advised us that VEBA AG or one of its affiliates may purchase rights
on the New York Stock Exchange during the pending rights offering. However, the
VEBA group has agreed not to exercise the over-subscription privilege with
respect to any rights. The VEBA group has also advised us that it may decide to
purchase additional shares of MEMC common stock following the rights offering.
 
 Restrictive Covenants Will, and Higher Interest Rates May, Apply to MEMC if
 VEBA AG or its Affiliates Cease to Own a Majority of Our Stock
 
     Certain of our loan agreements with VEBA AG and its affiliates provide that
if VEBA AG and its affiliates own less than a majority of the outstanding MEMC
common stock on or after January 1, 2001, then the interest rates we pay on our
loans from VEBA AG and its affiliates will be the higher of:
 
     - the interest rate currently set forth in each such loan agreement; or
 
     - an interest rate determined, as of the later of January 1, 2001 or the
       change of control date, for an average industrial borrower at an assumed
       credit rating based on the remaining term of each such loan agreement.
 
     In addition, in such an event we will become subject to certain affirmative
covenants set forth in all of our loan agreements with VEBA AG and its
affiliates. These affirmative covenants include requirements that we maintain a
minimum net worth and a minimum amount of working capital. We would also need to
meet certain financial ratios, including a minimum fixed charge coverage ratio
and minimum working capital ratio.
 
     If we had been subject to these covenants as of January 31, 1999, we would
not have been in compliance with all of these covenants. If VEBA AG and its
affiliates own less than a majority of our outstanding common stock at any time
on or after January 1, 2001 and we are then not in compliance with all of these
affirmative covenants, then we would be in default under these loan agreements.
 
     If VEBA AG and its affiliates own less than a majority of the outstanding
MEMC common stock, then Taisil Electronic Materials Corporation, our Taiwanese
joint venture, may become obligated to repay certain debt. See "Business -- Risk
Factors -- We May Have to Make Substantial Payments in Connection With Our
Taisil Joint Venture, and This Could Divert Funds From Other Needed Areas."
 
 We Experience Intense Competition in the Silicon Wafer Industry and Our
 Customers Expect Continuing Technological Innovation at a Low Cost
 
     We face intense competition in the silicon wafer industry from established
manufacturers throughout the world. If we cannot compete effectively with other
silicon wafer manufacturers, our operating results could be materially adversely
affected. Some of our competitors have substantial financial, technical,
engineering and manufacturing resources. We believe that our Japanese
competitors benefit from their dominance of the Japanese market, which
represented approximately 38% of the worldwide silicon wafer market in 1998. In
 
                                       13
<PAGE>   15
 
particular, Shin-Etsu Handotai, the largest supplier of silicon wafers in Japan
and the world, is able to leverage globally its sales and technology base.
 
     We compete principally on the basis of product quality, consistency and
price, as well as technical innovation, customer service and product
availability. We expect that our competitors will continue to improve the design
and performance of their products and to introduce new products with competitive
price and performance characteristics. Competitive pressures may cause
additional price reductions, which could have a material adverse effect on our
operating results.
 
  If We Fail to Make Significant Investments Necessary to Comply With Changing
  Semiconductor Industry Customer Specifications, We May Lose Customers
 
     If we fail to meet future customer requirements, we could experience a
material adverse effect on our competitive position and operating results. The
silicon wafer industry changes rapidly. Changes include requirements for new and
more demanding technology, product specifications and manufacturing processes.
Our ability to remain competitive will depend upon our ability to develop
technologically advanced products and processes. We must continue to meet the
increasingly demanding requirements of our customers on a cost-effective basis.
As a result, we expect to continue to make significant investments in research
and development. We cannot assure you that we will be able to successfully
introduce, market and cost-effectively manufacture any new products, or that we
will be able to develop new or enhanced products and processes that satisfy
customer needs or achieve market acceptance.
 
 We Have a Limited Number of Principal Customers, and Accordingly a Loss of One
 or Several of Those Customers Would Hurt Our Business
 
     Our operating results could materially suffer if we, or our joint ventures,
experience a significant reduction in, or loss of, purchases by one or more of
our top customers. Historically, we have sold a significant portion of our
products to a limited number of principal customers. In 1998, we made over
one-half of our sales to ten customers, with one customer accounting for
approximately 20% of our sales. Likewise, POSCO HULS Co., Ltd. (commonly known
as PHC), our unconsolidated joint venture in South Korea, sold over half its
products to Samsung, one of our partners in that joint venture. We cannot assure
you that we or PHC will realize equivalent sales from our top customers in the
future.
 
 Currency Exchange Rates and Increased Competition Have Reduced Wafer Prices and
 Have Led to Lower Margins and Profits
 
     Decreases in wafer prices have lowered our margins and profits. In 1998, we
had a gross margin of negative 4.2%. This negative gross margin was due in part
to the decline of the Japanese yen and the Deutsche mark relative to the U.S.
dollar over the past few years. Recently, the Japanese yen has recovered
moderately relative to the U.S. dollar. The currency declines have given, and
similar currency declines in the future may give, our Japanese and German
competitors significant cost advantages in the marketplace. These currency
pressures, together with the effects of the semiconductor industry downturn and
excess capacity in the silicon wafer industry, as described above, have
increased competition and resulted in significant decreases in wafer prices.
 
 We Expect that International Sales Will Continue to Represent a Significant
 Percent of Our Total Sales, and Accordingly We are Subject to Periodic Foreign
 Economic Downturns and Fluctuations in Foreign Currency Exchange and Interest
 Rates
 
     A number of factors in the past have affected adversely, and may affect
adversely in the future, our results of operations and international sales and
operations, including periodic economic downturns and fluctuations in interest
and foreign currency exchange rates.
 
     We expect that international sales will continue to represent a significant
percentage of our total sales. In addition, a significant portion of our
manufacturing operations are located outside of the United States. Sales outside
of the United States expose us to currency exchange rate fluctuations. Our risk
exposure from these
 
                                       14
<PAGE>   16
 
sales is primarily limited to the Japanese yen, Deutsche mark and European euro.
Our risk exposure from expenses at international manufacturing facilities is
concentrated in Italian lira, Japanese yen and Malaysian ringgit. We generally
hedge receivables denominated in foreign currencies at the time of sale. We
hedge some foreign currency denominated intercompany loans by entering into
long-dated forward exchange contracts. However, we cannot predict whether
exchange rate fluctuations will have a material adverse effect on our operations
and financial results in the future.
 
     Our unconsolidated joint ventures have sales denominated in the U.S. dollar
and manufacturing expenses primarily denominated in the U.S. dollar, Korean won
and New Taiwanese dollar. PHC also has significant debt denominated in the U.S.
dollar and Korean won. Likewise, Taisil Electronic Materials Corporation, our
unconsolidated Taiwanese joint venture, has significant debt denominated in the
U.S. dollar and New Taiwanese dollar. For U.S. generally accepted accounting
principles, these two unconsolidated joint ventures use the U.S. dollar as their
functional currency and do not hedge net Korean won or New Taiwanese dollar
exposures. We do not hedge our net Korean won exposure, because the forward
contract market is limited for the Korean won and we do not believe the prices
of such contracts are attractive. To date, we have not hedged net New Taiwanese
dollar exposure. However, given the increasingly broader market and depth for
forward contracts in both Korea and Taiwan, we may consider forward contracts in
the future.
 
     The economic downturns in the Asia Pacific region and Japan and the
devaluation of the Japanese yen against the U.S. dollar have affected and in the
future could affect our operating results. Additionally, other factors may have
a material adverse effect on our operations in the future including:
 
     - the imposition of governmental controls;
 
     - export license requirements;
 
     - restrictions on the export of technology;
 
     - political instability;
 
     - trade restrictions and changes in tariffs; and
 
     - difficulties in staffing and managing international operations.
 
     As a result, we may need to modify our current business practices.
 
 We May Have to Make Substantial Payments in Connection With Our Taisil Joint
 Venture, and This Could Divert Funds From Other Needed Areas
 
     As of January 31, 1999, Taisil had approximately $202.9 million of debt
outstanding. We have guaranteed approximately $75 million of such debt (which
may increase to approximately $81 million). Generally under the guarantees, if
VEBA AG's and its affiliates' ownership of MEMC common stock falls below 50% of
MEMC's total issued and outstanding shares, we become obligated to either pay,
or provide other collateral satisfactory to the banks, which may include a
letter of credit in an amount equal to, the maximum amount we may owe under the
guarantees.
 
     The terms of Taisil's loan agreements vary.  If Taisil defaults on its
obligations to its lenders, in some circumstances Taisil may immediately be
required to repay all of its obligations to its lenders. If Taisil is required
to make an immediate repayment of its obligations to its lenders, we may be
required to make payments on our guarantees of Taisil's debt. The circumstances
in which immediate repayment may occur include, without limitation:
 
     - a material adverse change in Taisil;
 
     - a reduction below 70% in the combined ownership of Taisil by the two
       major joint venture partners (us and China Steel Corporation);
 
     - a material adverse change in us or China Steel Corporation;
 
     - a reduction below 50% in VEBA AG's and its affiliates' ownership of MEMC
       common stock; or
 
                                       15
<PAGE>   17
 
     - other customary circumstances.
 
     We cannot assure you that Taisil's lenders will not declare a default on
Taisil's debt if they determine there has occurred a material adverse change, or
they determine a material adverse change occurs in the future, in Taisil or
MEMC. If MEMC is required to make payments on any guarantees, this would divert
capital needed to fund future operations.
 
     For more information about Taisil please see, "Business -- Joint
Ventures -- Taisil Electronic Materials Corporation."
 
  Because We Cannot Easily Transfer Production of Specific Products From One of
  Our Manufacturing Facilities to Another, Manufacturing Delays at a Single
  Facility Could Result in a Loss of Customers
 
     It typically takes six months for one of our customers to qualify one of
our manufacturing facilities to produce a specific product, but it could take
longer in today's environment of excess capacity. Interruption of operations at
any of our primary manufacturing facilities could result in delays or
cancellations of shipments of silicon wafers and a loss of customers which could
materially and adversely affect our operating results. A number of factors could
cause interruptions, including labor disputes, equipment failures, or shortages
of raw materials or supplies. A union represents employees at PHC's facility in
South Korea. A strike at this facility could cause interruptions in
manufacturing. We cannot assure you that alternate qualified capacity would be
available on a timely basis or at all.
 
 Much of Our Proprietary Information is Not Patented and May Not be Patentable
 
     Much of our proprietary information and technology relating to the wafer
manufacturing process is not patented and may not be patentable. We believe that
the success of our business depends in part on our proprietary technology,
information and processes and know-how. We generally try to protect our
intellectual property rights based on trade secrets and patents as part of our
ongoing research, development and manufacturing activities. Recently, we have
increased our efforts to obtain patent protection for our technology in response
to an increase in patent applications by our competitors. However, we cannot
assure you that we have adequately protected or will be able to adequately
protect our technology, that our competitors will not be able to utilize our
existing technology or develop similar technology independently, that the claims
allowed on any patents held by us will be broad enough to protect our technology
or that foreign intellectual property laws will adequately protect our
intellectual property rights.
 
 Some of Our Technology May Infringe on the Intellectual Property Rights of
 Third Parties Which May Subject Us to Costly Patent Litigation
 
     From time to time, we receive notices from substantial companies with
significant patent portfolios that we may be infringing certain of their patents
or other rights. We may receive more of these notices in the future. If such
companies were to assert any claims against us based on patents or other rights
described in existing notices, we believe, based on strategic and other
considerations, that we should be able to resolve them outside of litigation
without a material adverse effect to us; however, this conclusion is subject to
significant uncertainty. We expect to try to resolve these matters through
negotiation or, if necessary, by obtaining a license. However, if we are not
able to resolve these matters satisfactorily, or to obtain a license on
acceptable terms, we may face litigation. In that event, the ultimate outcome of
these matters could have a material adverse effect on our business, results of
operations or financial condition. Although third parties have not sued us based
on claims of infringement of intellectual property rights during the last
several years, we cannot assure you that third parties will not bring such suits
in the future. Competitors, suppliers and others frequently sue each other
regarding intellectual property rights in other technology industries, including
the semiconductor industry.

  Despite Our Efforts We Have Failed to Retain a Number of Experienced Upper and
  Middle Management, and as a Result We Face Challenges in Attracting and
  Retaining Qualified Personnel
 
     The loss of key personnel or the inability to hire and retain qualified
personnel could have a material adverse effect on our operating results. We are
dependent upon a limited number of key management and technical personnel. We
compete for personnel with other companies, academic institutions, government
entities and other organizations. Our future success will depend in part upon
our ability to attract and retain highly qualified personnel. We cannot assure
you that we will be successful in hiring or retaining qualified personnel, or
that any of our personnel will remain employed by MEMC.
 
     In March 1998, we adopted a special incentive bonus program designed to
retain the services of 24 of our officers and key employees, including eleven
then executive officers. Under this program, the participants received a special
bonus. Half of this bonus was paid when the participant entered into a special
incentive bonus agreement; the other half becomes payable on June 30, 1999,
subject to continued employment. If the participant's employment is terminated
under certain circumstances, that participant must repay us all or a portion of
the bonus the participant has already received. Despite this program, a number
of experienced members of upper and middle management have left MEMC.
 
  We Depend on Certain Suppliers and Finding Alternative Sources of Supply Could
  Affect Adversely Our Customer Qualifications and Manufacturing Yields
 
     We obtain substantially all our requirements for several raw materials,
equipment, parts and supplies from sole suppliers. We believe that we could find
adequate alternative sources of supply for these raw materials, equipment, parts
and supplies. However, we may be required to obtain new qualifications from our
customers in order to change or substitute suppliers. We cannot predict whether
we would be successful or how long that process would take. In addition, our
manufacturing yields could be adversely affected while we transition to a new
supplier. A decrease in our manufacturing yields could have a material adverse
effect on our operating results.
 
     From time-to-time we have experienced limited supplies of certain raw
materials, equipment, parts and supplies, particularly polysilicon. We believe
that adequate quantities of all our key raw materials, equipment, parts and
supplies are currently available. However, because of the cyclical nature of our
industry, we may experience shortages in the future. Increases in prices
resulting from these shortages could have a material adverse effect on our
operating results.
 
  Because the Public is Focusing More Attention on the Environmental Impact of
  Our Industry and Its Manufacturing Operations, Environmental Laws and
  Regulations May Become More Stringent in the Future and Could Force MEMC to
  Expend Capital to Comply with Such Laws
 
     Because the public is focusing more attention on the environmental impact
of the semiconductor and related industries' manufacturing operations,
environmental laws and regulations related to our industry may become more
stringent in the future. Any failure to comply with environmental laws could
subject us to substantial liability or could force us to significantly change
our manufacturing operations. We are subject to a variety of foreign, federal,
state and local laws and regulations governing the protection of the
environment. These environmental regulations include those related to the use,
storage, handling, discharge and disposal of toxic, volatile or otherwise
hazardous materials used in our manufacturing processes. Under some of these
laws and regulations, we could be held financially responsible for remedial
measures if our properties are contaminated, even if we did not cause such
contamination.
 
     In early 1998, a valve at our Italian facility malfunctioned, resulting in
a release of a hazardous gas. Governmental authorities are continuing to
investigate the incident and, in addition to private individuals, could seek to
assert claims against us. However, based on information currently available, we
do not believe any such claims should have a material adverse effect on us.
Also, we have been named as a defendant in two lawsuits with many other
defendants in which the plaintiffs allege damages related to environmental
problems.

  Our Fluctuating Financial Results, Our Position in the Silicon Wafer Industry
  and Our Relationship with VEBA may Create Fluctuations in the MEMC Stock Price
 
     Based on the trading history of MEMC common stock, we believe that certain
factors cause the market price of MEMC common stock to fluctuate significantly.
These factors include, without limitation:
 
     - quarterly fluctuations in our financial results;
 
     - announcements of technological innovations or new products by us or our
       competitors;
 
     - market conditions in the semiconductor industry;
 
     - market conditions in the silicon wafer industry;
 
     - developments in patent or other proprietary rights;
 
     - changes in our relationships with our customers;
 
     - any actual or perceived change in our relationship with VEBA AG and its
       affiliates; and
 
     - the size of the public float of MEMC common stock (which will depend, in
       part, on the number of shares of MEMC common stock purchased or acquired
       by rights holders other than by the VEBA group in our pending rights
       offering).
 
     Technology company stocks in general have experienced extreme price and
trading volume fluctuations that often have been unrelated to the operating
performance of these companies. This market volatility may adversely affect the
market price of MEMC common stock. In addition, if we suffer an actual or
anticipated shortfall in net sales, gross margin or net earnings from security
analysts' expectations, the trading price of MEMC common stock in any given
period could decline.

facility at the end of the lease. We also lease our small diameter facility in
Sherman, Texas. The initial term of this lease expires in 2001 and is extendable
at our option for three (3) additional renewal terms of five (5) years each. We
lease our facility in Pasadena, Texas. The term of the Pasadena lease expires in
2030 and is extendable for four (4) additional renewal terms of five (5) years

This lease expires in 2014. We also lease our facilities in Luoyang, China and
Kuala Lumpur, Malaysia. These leases expire in 2012 and 2000, respectively.
 
     In 1999, we intend to close our facility in Spartanburg, South Carolina and
withdraw from our joint venture participation in the facility in Luoyang, China.
 
     We believe that our existing facilities and equipment are well maintained,
in good operating condition and are adequate to meet our current requirements.
The extent of utilization of these facilities varies from plant to plant and
from time to time during the year.
 
ITEM 3.  LEGAL PROCEEDINGS
 
  Equipment Purchase Dispute
 
     We have a dispute with a manufacturer of equipment for the production of
silicon wafers. The dispute involves our cancellation of an order for a number
of pieces of equipment. The manufacturer claims that we are obligated for
approximately $5 million for costs related to the cancelled order, including the
cost of inventory it has on hand and on order with its vendors. We are in the
process of evaluating the merits of the manufacturer's claim. The manufacturer
has advised us that if we are unable to resolve this dispute, it will file suit
against us. While we will assert all of our defenses in this dispute, we cannot
assure you that we will be able to resolve this dispute on terms favorable to
us.
 
  Litigation Related To MEMC Pasadena
 
     In a case entitled Damewood vs. Ethyl Corporation, et al., (Case No.
96-38521), filed on August 1, 1996, three employees of the former operator of
MEMC Pasadena's plant, Albemarle Corporation, filed suit against us and others
in the 189th Judicial District Court, Harris County, Texas. The employees
alleged that they sustained injuries during an explosion at that plant on
January 27, 1996. We have settled this matter with plaintiffs and have been
dismissed as a party. One of the other defendants, Ethyl Corporation, was the
only defendant in this case at the time of trial in October 1998. A jury awarded
a verdict against Ethyl Corporation in the amount of $6.1 million.
 
     In July of 1996, two employees of the former operator of the MEMC Pasadena
plant were injured when flaming liquid escaped from a valve under repair. These
individuals filed suit on June 13, 1997, against us and others in a case
entitled Parden vs. Ethyl Corporation, et al. (Case No. 97-34857) in the 61st
Judicial District Court, Harris County, Texas. Plaintiffs are seeking actual and
exemplary damages in an unstated amount. We believe that we have meritorious
defenses to this cause of action. This case is currently set for trial on August
16, 1999.
 
     A demand against us for defense and indemnity in both these cases was made
on behalf of Ethyl Corporation by Albemarle Corporation on September 29, 1998.
Albemarle Corporation has assumed the obligation to defend and indemnify Ethyl
Corporation under an agreement in which Ethyl Corporation transferred ownership
of the plant where the injury took place to Albemarle Corporation. Albemarle
Corporation's demand for defense and indemnification against us on behalf of
Ethyl Corporation is under evaluation by our counsel. In early November, we made
a demand for indemnity in these cases against Albemarle. Demands for indemnity
made by Albemarle Corporation on behalf of Ethyl Corporation and by us are both
based on contractual indemnity language contained in the contract for the sale
of the MEMC Pasadena plant from Albemarle Corporation to us.
 
     In October 1997, a flash ignition occurred at the MEMC Pasadena plant.
Eleven employees of U.S. Contractors, Inc., a construction contractor, received
injuries from the impact. Three of these individuals have filed suit against us,
Albemarle Corporation and another party for injuries allegedly sustained in this
accident in a case entitled Larry Lambert, Andres Garcia and Rogers Patino vs.
MEMC Pasadena, Inc.,
 
                                       21
<PAGE>   23
 
(Cause No. 97-61639). The case was filed in the 152nd Judicial District, Harris
County, Texas. Two of these individuals allege head injuries and all three
allege hearing loss. The plaintiffs are seeking actual, punitive and exemplary
damages against the defendants in an unstated amount. We believe all of the
defendants have significant defenses to the plaintiffs' claims.
 
     Pursuant to a construction contract between us and U.S. Contractors, Inc.,
U.S. Contractors, Inc. originally agreed to defend and indemnify us in this suit
up to $25 million. Under a contract between us and Albemarle Corporation, we are
contractually obligated to defend Albemarle Corporation in this suit. We have
also made a demand upon U.S. Contractors, Inc. to defend and indemnify Albemarle
Corporation pursuant to the construction contract between us and U.S.
Contractors, Inc. U.S. Contractors, Inc.'s insurance carrier has recently
indicated to us that it disputes the obligation of U.S. Contractors, Inc. to
defend and indemnify us and Albemarle Corporation despite U.S. Contractors,
Inc.'s prior agreement to defend and indemnify us.
 
     On March 18, 1999, the parties agreed in principal to a settlement of the
foregoing matter which will be completely covered by insurance. We anticipate
that the parties will execute agreements reflecting this settlement in the next
several weeks.
 
     Due to uncertainty regarding the litigation process, the scope and
interpretation of contractual indemnity provisions and the status of any
insurance coverage or pending settlements, we cannot assure you that the
ultimate outcome of the foregoing matters will not have a material adverse
effect on us.
 
  Texas Nuisance Actions
 
     In a case entitled Crye, et al. vs. Reichhold Chemicals, Inc., et al. (Case
No. 97-24399), over 7,000 plaintiffs filed suit against MEMC Pasadena and
approximately 31 other companies operating industrial facilities along I-10 and
along the Houston Ship Channel in Harris County, Texas. The suit was filed in
the 334th Judicial District, Harris County, Texas. MEMC Pasadena was served in
this matter on December 30, 1998. In a similar case entitled Gerlich, et al. vs.
Merichem Company, et al. (Case No. 98-59745), almost 400 plaintiffs filed suit
against MEMC Pasadena and approximately 26 other companies operating industrial
facilities along I-10 and along the Houston Ship Channel in Harris County,
Texas. The suit was filed in the 80th Judicial District, Harris County, Texas.
MEMC Pasadena was served in this matter on February 2, 1999.
 
     In both cases, plaintiffs allege that defendants have discharged various
pollutants into the air, soil, ground and surface water. Plaintiffs also allege
that these facilities generate deafening noise, sickening foul odors and glaring
and intrusive lights. Plaintiffs have sued all defendants alleging nuisance,
trespass, negligence and gross negligence. Plaintiffs are seeking an injunction
and actual and exemplary damages in an unstated amount. We are in the process of
evaluating these lawsuits. Because these suits were only recently served on us,

                          INDEPENDENT AUDITORS' REPORT
 
To the Stockholders and Board of Directors
POSCO HULS Co., Ltd.:
 
     We have audited the accompanying balance sheets of POSCO HULS Co., Ltd. as
of December 31, 1998 and 1997, and the related statements of operations,
appropriation (disposition) of retained earnings (deficit) and cash flows for
each of the years in the three-year period ended December 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 the Auditing Standards, as
established by the Financial Supervisory Commission of the Republic of Korea,
which are substantially similar, in all material aspects, to generally accepted
auditing standards in the United States. 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.
 
     As discussed in note 1(b) to the financial statements, the operations of
the Company have been significantly affected and will continue to be affected
for the foreseeable future by the liquidity crisis and related adverse economic
circumstances in the Republic of Korea.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of POSCO HULS Co., Ltd. as of
December 31, 1998 and 1997, and the results of its operations, the changes in
its retained earnings (deficit), and its cash flows for each of the years in the
three-year period ended December 31, 1998 in conformity with the Financial
Accounting Standards, as established by the Financial Supervisory Commission of
the Republic of Korea.
 
     The Financial Accounting Standards in the Republic of Korea, as established
by the Financial Supervisory Commission of the Republic of Korea, vary in
certain significant respects from generally accepted accounting principles in
the United States. Application of generally accepted accounting principles in
the United States would have affected results of operations for each of the
years in the three-year period ended December 31, 1998 and stockholders' equity
as of December 31, 1998 and 1997, to the extent summarized in note 18 to the
financial statements.

                         NOTES TO FINANCIAL STATEMENTS
                        DECEMBER 31, 1998, 1997 AND 1996
                         (IN THOUSANDS OF U.S. DOLLARS)
 
(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Basis of Presenting Financial Statements
 
     The accounting records of Posco HULS Co., Ltd. (the "Company") are
expressed in Korean Won and maintained in accordance with the Financial
Accounting Standards of the Republic of Korea, which may differ in some material
respects from International Accounting Standards or the accounting principles
and standards of the country of the reader. The accompanying financial
statements have been extracted from the Company's Korean language financial
statements that were prepared using accounting principles and reporting
practices generally accepted in the Republic of Korea. The financial statements
and the auditors' report have been translated from those issued in Korea, from
the Korean language into the English language, and have been modified to allow
for formatting of the financial statements in a manner different from the
presentation under Korean financial statements practices. Certain modifications
have been made in the accompanying financial statements to bring the formal
presentation into conformity with practices outside of Korea, and certain
information included in the Korean language statutory financial statements,
which management believes is not required for a fair presentation of the
Company's financial position or results of operations, is not presented in the
accompanying financial statements. The accompanying financial statements are not
intended to present the financial position and results of operations and cash
flows in accordance with accounting principles and practices generally accepted
in countries and jurisdictions other than Korea.
 
     The Company's financial position and results of operations are presented
utilizing a reporting currency of U.S. dollars. The U.S. dollar amounts are
determined by translating the Korean Won amount of assets and liabilities into
U.S. dollars at the basic exchange rate as of the balance sheet date (-1,207.80
to US$1 and -1,695.80 to US$1 (except for amounts denominated in foreign
currencies at December 31, 1997, which are translated at -1,415.20 to US$1 (see
note 1(k))) as of December 31, 1998 and 1997, respectively), the amount of
common stock at the basic exchange rate on the date of issuance, and income and
expense items at the average basic exchange rate for the year (-1,415.62 to
US$1,-952.84 to US$1 and -807 to US$1 for the years ended December 31, 1998,
1997 and 1996, respectively). The effect of changes in exchange rates are
reflected as "cumulative translation adjustment" within stockholders' equity.
 
  (b) Economic Environment
 
     In 1998, the continued adverse economic conditions in the Republic of Korea
and other countries in the Asia Pacific region, which began in 1997, continued
to result in, among others, a national liquidity crisis, higher domestic
interest rates, reduced opportunities for refinancing or refunding of maturing
debts, and a general reduction in spending throughout the region. In order to
partially address this situation, the Government of the Republic of Korea
received assistance from the International Monetary Fund and announced a
comprehensive policy package intended to address the structural weaknesses in
the Korean economy and financial sector. While the reform policies are intended
to alleviate the economic crisis in Korea and improve the economy over time, the
immediate effects have included and could continue to include, among others,
slower or negative economic growth, a reduction in the availability of credit,
an increase in interest rates, an increase in taxes, an increased rate of
inflation, devaluation of the Korean Won, an increase in the number of
bankruptcies of Korean companies, and labor unrest resulting from the increase
in unemployment. The impact of these and other factors have had and could
continue to have a material adverse effect on the financial position and results
of operations of the Company. The accompanying financial statements reflect
management's current assessment of the possible impact of this economic
situation on the financial position of the Company.
 
     The effect on the Company's financial position of future developments and
access to further financial information concerning the Company's customers,
suppliers, financiers and others and their ability to continue

to transact with the Company cannot presently be determined. The financial
statements therefore may not include all adjustments that might ultimately
result from these adverse economic conditions.
 
  (c) Marketable Securities
 
     Marketable securities, which are certificates of deposit, are stated at
cost plus incidental expenses, determined by the weighted average method.
 
  (d) Inventories
 
     Inventories, excluding materials-in-transit, are stated at the lower of
cost (the weighted average method) or market value. Materials-in-transit are
valued at cost determined by the individual identification method.
 
  (e) Fixed Assets
 
     Fixed assets are stated at cost. The Company charges maintenance, repairs
and minor renewals to expense as incurred. Major renewals and improvements are
capitalized. Interest incurred during the construction and installation of
manufacturing plant is capitalized as part of fixed assets.
 
     Depreciation is computed by the straight-line method at rates based on the
following estimated useful lives:

  (f) Accounting for Leases
 
     The Company accounts for leases as operating or financing leases in
accordance with the Accounting Standards for Leases.
 
     Under the operating lease method, lease expenses are charged to operations
as actual payments are made or due. Prepaid lease expense relating to operating
leases is amortized over the lease term of the related lease.
 
     Under the financing lease method, the principal amount of leased equipment,
which is the present value of total minimum lease payments, is recorded as a
leased asset and a long-term obligation under financing leases. The leased
assets are amortized over the term of the related lease. Interest expense on
long-term obligations under financing leases is recorded when incurred.
 
  (g) Deferred Charges
 
     Deferred charges are stated at cost less accumulated amortization. Bond
issue costs are amortized over the repayment period of the related bonds.
Deferred foreign currency translation loss is amortized over the remaining
repayment period of the respective assets and liabilities.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (h) Discount on Bonds Issued
 
     Discount on bonds issued is amortized over a period from the date of issue
to the maturity of the related bonds using the straight-line method.
 
  (i) Retirement and Severance Benefits
 
     Employees who have been with the Company for more than one year are
entitled to lump-sum payments based on current rates of pay and length of
service when they leave the Company. The Company's estimated liability under the
plan has been accrued in the accompanying financial statements at the amount
which would be payable if all employees left the Company at the balance sheet
date.
 
     Under the National Pension Scheme of Korea, the Company is required to
transfer a certain portion of retirement allowances of employees to the National
Pension Fund. The amount transferred will reduce the retirement and severance
benefit amount payable to the employees when they leave the Company and is
reflected as a reduction of the retirement and severance benefits liability in
the accompanying financial statements.
 
     The Company has covered 37% and 41% of the retirement and severance
benefits liability as of December 31, 1998 and 1997, respectively by insurance
policies, which is included in the investments and other assets account as
deposits for retirement and severance benefits.
 
  (j) Revenue Recognition
 
     Local sales are recognized when goods are delivered and inspection by the
customer is completed, while export sales are recognized as of the shipment
date.
 
  (k) Foreign Currency Translation
 
     Monetary assets and liabilities denominated in foreign currencies are
translated into Korean Won at the balance sheet date. In accordance with a
change in financial accounting standards in the Republic of Korea in 1997, net
losses on long-term foreign currency denominated monetary assets and liabilities
and the current portion of long-term debt denominated in foreign currencies are
permitted to be recorded as a deferred foreign currency translation loss and
amortized over the remaining repayment period of the respective assets and
liabilities. In 1996, such gains or losses were recorded in current results of
operations. The 1996 financial statements are not affected by such change in
financial accounting standards.
 
     As of December 31, 1998 and 1997, monetary assets and liabilities
denominated in a foreign currency are translated into Korean Won at -1,207.80 to
US$1 and -1,415.20 to US$1, respectively, the rates of exchange permitted under
the financial accounting standards in the Republic of Korea. On December 31,
1997, the basic rate of exchange was -1,695.80 to US$1. Had the basic rate of
exchange been used to translate foreign currency assets and liabilities as of
December 31, 1997, the net earnings reported by the Company would be reduced by
$5,606 for the year ended December 31, 1997. The difference in these exchange
rates has no impact on the US GAAP reconciliation as presented in Note 18.
 
  (l) Income Taxes
 
     Provision is not made in the accounts to reflect the future tax benefit
(expense) on the interperiod allocation of income taxes resulting from certain
income and expense items being treated differently for financial reporting
purposes than tax computation purposes.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (m) Earnings (Loss) Per Share
 
     Earnings (loss) per common share is calculated by dividing net earnings
(loss) by the weighted average number of shares of common stock outstanding
during each period.
 
  (n) Statement of Cash Flows
 
     For purposes of the statement of cash flows, the Company considers all
highly liquid marketable securities with a maturity of three months or less to
be cash equivalents.
 
  (o) 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 expense during the period.
Actual results could differ from those estimates.
 
  (p) Significant Changes in Financial Accounting Standards in Korea
 
     On December 11, 1998, the Financial Supervisory Commission announced
certain changes in the Financial Accounting Standards in the Republic of Korea
("Korean GAAP"). The revised accounting standards are applicable for fiscal
years starting on or after January 1, 1999. The more significant changes
affecting the Company are as follows:
 
          (i) Deferred Income Tax  Currently under Korean GAAP, no provision is
     made to reflect the interperiod allocation of income and expense items
     being treated differently for financial reporting purpose than income tax
     purposes. Under revised Korean GAAP, income tax expense shall be computed
     by applying the statutory rate to income (loss) before income tax expense.
     Accordingly, differences in the manner in which certain income and expense
     items are treated for financial reporting and income tax purposes will
     require the recognition of deferred income tax debits and credits.
 
          (ii) Foreign Currency Translation  Currently under Korean GAAP,
     certain unrealized foreign currency translation gains and losses on
     non-current monetary assets and liabilities are permitted to be excluded
     from results of operations and recognized as a deferred credit and a
     deferred asset, respectively. Under revised Korean GAAP, all unrealized
     foreign currency translation gains and losses on monetary assets and
     liabilities are to be included in results of operations. Amounts deferred
     as of December 31, 1998 will be charged or credited to retained earnings as
     of January 1, 1999.
 
          (iii) Impairment of Long-lived Assets  Currently under Korean GAAP,
     there is no accounting standard regarding the impairment of long-lived
     assets. Under revised Korean GAAP, a valuation allowance will be required
     where there has been a material decline in the value of long-lived assets.
 
          (iv) Investments  Currently under Korean GAAP, investments in debt
     securities are carried at amortized cost. Under revised Korean GAAP,
     investments in debt securities are to be carried at market value, unless
     they are intended to be held to maturity in which case they may continue to
     be carried at amortized cost.
 
          (v) Deferred and Intangible Assets  Currently under Korean GAAP,
     pre-operating costs, stock issuance cost, debt issuance costs, and research
     and development costs may be deferred and amortized over future periods.
     Under revised Korean GAAP, pre-operating costs (other than corporate
     organization costs) must be expensed as incurred, stock issuance costs must
     be recognized as a reduction of stockholders' equity, debt issuance costs
     must be reflected as a discount in the related debt, and research costs
     must be expensed as incurred (development costs may be deferred and
     amortized over 5 years provided such costs are recoverable from future
     earnings).

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
          Currently under Korean GAAP, goodwill is amortized over 5 years. Under
     revised Korean GAAP, goodwill may be amortized over periods up to 20 years.
 
          (vi) Prior Period Error Corrections  Currently under Korean GAAP,
     prior period error corrections are included in results of operations. Under
     revised Korean GAAP, prior period financial statements shall be restated to
     reflect such corrections, if material.
 
          (vii) Transfers of Receivables with Resources  Currently under Korean
     GAAP, transfers of receivables on which the Company is continently liable
     are recognized as sales of receivables. Under revised Korean GAAP, such
     transactions must be treated as borrowings; only transfers of receivables
     without recourse may be treated as sales.
 
          (viii) Accounting Changes  Currently under Korean GAAP, accounting
     changes are applied on a prospective basis.
 
          Under revised Korean GAAP, the cumulative effect of changes in
     accounting principles will be charged to retained earnings at the beginning
     of the year.
 
          (ix) Other  Under revised Korean GAAP, certain disclosures will be
     required for segments, discontinued operations, and material breaches in
     debt agreements. Currently under Korean GAAP, no such disclosures are
     required.
 
     The Company plans to adopt the changes on a prospective basis from January
1, 1999. The Company has not yet determined the impact that adoption of the
revised accounting standards will have on its financial statements.

     The Korean Commercial Code requires the Company to appropriate as legal
reserve an amount equal to at least 10% of cash dividends for each accounting
period until the reserve equals 50% of stated capital. This legal reserve may be
used to reduce a deficit or it may be transferred to common stock as a stock
dividend.
 
     Under the Tax Exemption and Reduction Control Law, the Company is allowed
to make certain deductions from corporate income taxes. The Company is, however,
required to appropriate from retained earnings the amount of the tax benefit
obtained and transfer such amount into a reserve for business rationalization.
This legal reserve may be used to reduce a deficit or may be transferred to
common stock as a stock dividend.
 
     Under the Tax Exemption and Reduction Control Law, the Company is allowed
to make certain deductions from taxable income and set up reserves for
technology development, reserve for export loss and reserve for overseas market
development by appropriating retained earnings. The unused portion of the
reserves is generally added back to taxable income over three to four years
after a certain grace period. These voluntary reserves may be restored to
unappropriated retained earnings by a future stockholders' resolution.
 
(15) INCOME TAXES
 
     The Company is subject to a number of taxes based upon taxable earnings

(18) RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
 
     The accompanying financial statements are prepared in accordance with
Korean GAAP, which differ in certain significant respects from generally
accepted accounting principles in the United States (U.S. GAAP). The significant
differences are described below. Other differences do not have a significant
effect on either consolidated net earnings (loss) or stockholders' equity. The
estimated effects of the significant adjustments to

     For Korean GAAP presentation, the Company records gains and losses through
its statement of operations for changes in currency rates effecting monetary
assets and liabilities denominated in dollars. For US GAAP purposes, the US
dollar is the functional currency. Thus, for US GAAP purposes, currency gains
and losses result from changes in currency exchange rates related to monetary
assets and liabilities denominated in Korean won. The differences between the
currency gains and losses calculated under the two different sets of assumptions
appear as adjustments in reconciling Korean GAAP net earnings (loss) to net
earnings (loss) under US GAAP.

     For US GAAP purposes fixed assets are depreciated over longer lives than
for Korean GAAP purposes. Additionally, fixed assets are presented in the Korean
GAAP financial statements using a translation rate in effect at the balance
sheet date. For US GAAP purposes, the US dollar is the functional currency.

Accordingly, fixed assets are translated at rates in effect at the acquisition
date of the various assets. As a result, in reconciling from Korean GAAP to US
GAAP stockholders' equity, positive adjustments result both from the longer life
used for US GAAP as well as translating the gross asset basis, and accompanying
accumulated depreciation, at rates different than for Korean GAAP.

</TABLE>
 
  (a) Deferred Income Taxes
 
     Under Korean GAAP, a provision is not made in the accounts to reflect the
future tax effects resulting from certain income and expense items being treated
differently for financial reporting purposes and tax computation purposes.
 
     However, U.S. GAAP requires the recognition of deferred tax assets and
liabilities created by temporary differences between the financial statement and
tax bases of assets and liabilities. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled.
 
     The tax rate used to calculate deferred tax assets and liabilities was
changed from 18.5% in 1996 to 20.3% in 1997, and was further increased to 23.8%
in 1998 to reflect the normal corporation tax rate and exemptions statutorily
available under FCIL. The effect of this increase on the effective tax rate was
to increase the net deferred tax asset, increase net earnings by $5,401 in 1997
and decrease net loss by $291 in 1998.
 
  (b) Pre-Operating and Start-Up Costs
 
     Certain pre-operating and start-up costs are deferred for Korean GAAP and
amortized in equal annual amounts over 5 years from 1993. These costs would be
expensed as incurred under U.S. GAAP.
 
  (c) Capital Leases
 
     Under Korean GAAP, the Company has leased certain equipment and machinery
and accounts for such leases as operating leases. However, under U.S. GAAP those
leases would be classified as capital leases. Under U.S. GAAP, equipment under
capital lease is recorded as an asset and a liability is recorded for the
present value of minimum lease payments at the inception of the lease. This
equipment is depreciated over the estimated useful life of the asset.
 
  (d) Useful Life of Machinery and Equipment
 
     In 1995, the Company changed the estimated useful life of certain machinery
to 4 years from 6 years. For U.S. GAAP purposes, the Company continues to
depreciate the machinery and equipment over its estimated useful life of 6
years.
 
     Recoverability of assets to be held and used is measured by a comparison of
the carrying amount of an asset to future net cash flows expected to be
generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell. There is no indication of impairment of property, plant and equipment at
December 31, 1998 and 1997.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (e) Inventories
 
     For U.S. GAAP, inventories are adjusted for the effect of capitalized
depreciation in beginning and ending inventory balances relating to the
differences in useful lives of machinery and equipment and to depreciation on
capitalized interest.
 
  (f) Depreciation on Capitalized Interest
 
     In 1994, the Company recorded a prior year adjustment under Korean GAAP for
interest that should have been capitalized to construction-in-progress in 1993
and is being depreciated over the useful life of the related fixed assets. For
U.S. GAAP purpose, the interest amount was charged to earnings in 1993.
 
  (g) Foreign Currency Translation
 
     In accordance with a change in Korean GAAP in 1997, net foreign exchange
losses on long-term foreign currency denominated monetary assets and liabilities
and the current portion of long-term debt denominated in foreign currencies are
recorded as a deferred foreign currency translation loss and amortized over the
remaining repayment period of the respective assets and liabilities. In 1996,
such losses were expensed as incurred. However, for U.S. GAAP purposes, all such
foreign currency transaction losses are expensed as incurred in all periods.
 
  (h) Functional Currency
 
     Under U.S. GAAP, the Company considers the U.S. dollar as its functional
currency. Accordingly, the accounting bases of nonmonetary assets and
liabilities, primarily property, plant and equipment are reflected at the
historical exchange rate when the transaction occurred, foreign currency
exchange gains and losses under Korean GAAP are reversed, and exchange gains and
losses are recognized on Won-denominated monetary assets and liabilities. The
effects of using the U.S. dollar as the functional currency are included in the
U.S. GAAP reconciliation information.
 
  (i) Restatement of U.S. GAAP
 
     As discussed in note 18(h), the Company reports its financial position and
results of operations using the U.S. dollar as the functional currency under
U.S. GAAP. Originally reported net earnings and stockholders' equity under U.S.
GAAP reflected the use of the U.S. dollar as the functional currency only for
periods after September 30, 1997. Accordingly, net earnings and stockholders'
equity under U.S. GAAP have been restated as follows:

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Taisil Electronic Materials Corporation:
 
     We have audited the accompanying balance sheets of Taisil Electronic
Materials Corporation as of December 31, 1998 and 1997 and the related
statements of operations, changes in stockholders' equity and cash flows for the
years then ended. 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 auditing standards generally
accepted in the Republic of China, which are substantially similar to auditing
standards generally accepted in the United States. 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 Taisil Electronic Materials
Corporation as of December 31, 1998 and 1997, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles in the Republic of China.
 
     The accompanying financial statements for the year ended December 31, 1996
were not audited by us and, accordingly, we express no opinion or other form of
assurance on the financial statements for the year ended December 31, 1996.
 
     As discussed in note (2)(j) to the financial statements, as of December 31,
1997, Taisil Electronic Materials Corporation changed its method of accounting
for pensions.
 
     Accounting principles generally accepted in the Republic of China vary in
certain significant respects from generally accepted accounting principles in
the United States. Application of generally accepted accounting principles in
the United States would have affected stockholders' equity as of December 31,
1998 and 1997, and the results of operations for the years then ended to the
extent summarized in note 15 to the financial statements.

                    TAISIL ELECTRONIC MATERIALS CORPORATION
 
                         NOTES TO FINANCIAL STATEMENTS
                (AMOUNTS EXPRESSED IN THOUSANDS OF US DOLLARS OR
                  NEW TAIWAN DOLLARS, UNLESS OTHERWISE STATED)
          (AMOUNTS AND INFORMATION WITH RESPECT TO 1996 ARE UNAUDITED)
 
(1) ORGANIZATION AND BUSINESS ENVIRONMENT
 
     Taisil Electronic Materials Corporation (the "Company"), was founded in the
Hsinchu Science-Based Industrial Park of the Republic of China ("ROC") on
September 26, 1994. Prior to June 30, 1996, the Company was a development stage
enterprise whose activities primarily involved the construction of its
manufacturing facilities, financial planning, testing equipment, and recruiting
and training employees. The Company started its main activities of research,
development, production and sale of the latest generation silicon wafers in July
1996.
 
     The operations of the Company have been affected, and may continue to be
affected, by the currency devaluations and general deterioration of the
economies of countries in the Asia Pacific region. The Company does not,
however, expect the currency valuation problems and potential slowdown in Asian
economies to have a significant long-term effect on its financial position.
 
     The accompanying financial statements reflect management's current
assessments of the possible impact of this economic situation on the financial
position of the Company. Actual results could differ from management's current
assessments. In addition, the effect on the Company's financial position of
future developments and access to further financial information concerning the
Company's customers, suppliers, financiers and others and their ability to
continue to transact with the Company cannot presently be determined.
 
(2) SIGNIFICANT ACCOUNTING POLICIES
 
  (a) Generally accepted accounting principles
 
     The financial statements have been prepared in accordance with accounting
principles generally accepted in the Republic of China ("ROC GAAP"). ROC GAAP
varies in certain significant respects from accounting principles generally
accepted in the United States of America ("US GAAP"). Application of US GAAP
would have affected stockholders' equity as of December 31, 1998 and 1997, and
the results of operations for each of the two years then ended, to the extent
summarized in note 15.
 
  (b) Foreign currency transactions
 
     Foreign currency transactions in currencies other than the functional
currency are recorded at rates in effect at the transaction dates. Monetary
assets and liabilities denominated in foreign currencies at year-end are
translated at the exchange rate then prevailing. Gains or losses resulting from
settlement of such transactions or translations are included in non-operating
income.
 
  (c) Cash equivalents
 
     The Company considers commercial paper and bank acceptances, with a
maturity of less than three months from the date of purchase and time deposits
as cash equivalents.
 
  (d) Short-term investments
 
     Investments are carried at the lower of cost or market value. The market
value of unlisted trust funds is determined on the basis of the trust fund's net
worth on the balance sheet date. Costs of sale of investments are determined on
the weighted-average basis.

                    TAISIL ELECTRONIC MATERIALS CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  (e) Inventories
 
     Inventories are stated at the lower of cost or market value. Cost is
determined using the weighted-average method. The market value of raw materials
is determined on the basis of replacement cost. Market values of work in process
and finished goods are determined on the basis of net realizable value.
 
  (f) Long-term investments
 
     Long-term investments in equity securities that are not publicly traded in
which the Company owns less than 20% of the investee's common stock and does not
exercise significant influence over the investee's operations, are stated at the
cost.
 
  (g) Property, plant and equipment
 
     Property, plant and equipment are stated at acquisition cost which includes
the capitalization of interest and certain expenses incurred in connection with
the construction of plant and installation of machinery and equipment.
Depreciation on plant and equipment is provided on the straight-line method over
the estimated useful lives of the respective assets.
 
     Property, plant and equipment is reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. For purposes of evaluating the recoverability of property, plant
and equipment, the estimated future undiscounted net cash flows of each
operational gross of assets is compared to the carrying amount of the assets. If
the carrying amount exceeds the undiscounted cash flows, the impairment is
measured based on the fair values of the assets. At December 31, 1998, the
estimated future undiscounted net cash flows of property, plant and equipment
exceeded their carrying amount.
 
  (h) Technology fees
 
     The Company has entered into a technical assistance service agreement with
MEMC Electronic Materials, Inc. involving information and processes embodying
technology, equipment design, and assets and property rights for the manufacture
of silicon wafers. Payments for such technology are capitalized and amortized
over five years from the commencement of commercial production.
 
  (i) Organization cost and deferred charges
 
     The costs incurred in the establishment of the Company are capitalized and
amortized over five years commencing from the start of commercial operations.
Charges for the installation of gas and power systems are included in other
assets and amortized over five years.
 
  (j) Employee retirement plan
 
     The Company adopted a retirement plan covering substantially all employees
in December 1995. Benefits are based on the employees' years of service.
Starting in August 1996, in accordance with ROC Labor Standards Law, the Company
made monthly contributions to a pension fund with the Central Trust of China. As
approved by the authorities, the funding rate was set at 2% of salaries and
wages. Pension cost is recognized based on the amount to be appropriated.
Retirement benefits to employees will be paid from the retirement fund first,
and if the fund is insufficient, the balance will be charged to current
operations.
 
     Effective December 31, 1997, the Company adopted ROC Statements of
Financial Accounting Standards ("SFAS") No. 18, "Accounting for Pensions," for
its retirement plan. Based on the provisions of SFAS No. 18, pension costs
charged to earnings are actuarially computed. The measurement date was the
balance sheet date. Accrued pension liabilities were recognized for the excess
of accumulated benefit

obligation over fair value of plan assets. Net periodic pension costs including
current service cost and net obligation at transition which are amortized over a
27 year period based on the straight-line method, are recognized starting in
1998. The effect of this accounting change increased the net loss by
approximately $288 in 1998.
 
  (k) Income taxes
 
     Under the asset and liability approach of SFAS No. 22, deferred tax
liabilities are recognized for tax consequences of taxable temporary differences
by applying enacted statutory tax rates. Deferred tax assets are recognized for
tax consequences of deductible temporary differences, tax credits and operating
loss carryforwards. A valuation allowance is provided when some portion or all
of the deferred tax assets is not expected to be realized. Deferred income tax
is reported in the financial statements as a current or noncurrent item based on
the classification of the related asset or liability which causes the temporary
differences. Deferred income taxes not relating to assets or liabilities are
classified as current or noncurrent based on the expected period that the
temporary differences will reverse.
 
  (l) Forward exchange rate contracts
 
     The Company enters into foreign currency forward contracts to hedge future
operating cash outflows in currencies other than the functional currency.
Foreign currency forward contracts reduce the Company's exposure to the risk
that eventual foreign currency cash outflows will be adversely affected by
changes in exchange rates. Foreign currency gains and losses under the above
arrangements are not deferred as the cash flows being hedged do not represent
firm commitments. Foreign currency forward contracts are entered into with major
commercial European banks that have high credit ratings. From time to time, the
Company uses foreign currency forward contracts to hedge purchases of capital
equipment. Foreign currency gains and losses for such purchases are deferred as
part of the basis of the asset.
 
  (m) Restatement of Financial Statements
 
     The Company reports its financial position and results of operations using
the US dollar as the functional currency. Previously reported results of
operations and stockholders' equity reflected the use of the US dollar as the
functional currency only for periods after September 30, 1997. Accordingly, net
loss, net loss per share and stockholders' equity have been restated from
amounts originally reported as follows:

(11) STOCKHOLDERS' EQUITY
 
  (a) Capital stock
 
     On July 17, 1996, the stockholders' meeting approved the issuance of an
additional 55,000,000 shares at NT$10 par value per share for cash on July 17,
1996.
 
     On July 25, 1997, the stockholders' meeting approved a proposal to increase
authorized capital stock to 480,000,000 shares at NT$10 par value per share and
to issue an additional 60,000,000 shares at NT$10 par value per share for cash
on December 25, 1997. After this capital increase, the total issued capital was
$113,783.
 
     On February 5, 1998, the board of directors decided to issue an additional
85,000,000 shares at NT$10 per value per share for cash. After this capital
increase, the total issued capital was $139,887. The above increases were all
registered and approved by the authorities.
 
     On October 12, 1998, December 14, 1998 and January 11, 1999, the board of
directors decided to issue an additional 75,000,000, 35,000,000 and 90,000,000
shares at NT$10 par value per share for cash. On December 14, 1998, the special
stockholders' meeting approved the deduction of capital by 200,000,000 shares at
NT$10 par value to offset the accumulated deficit. The effective date of above
increase and decrease of capital has not been determined. Prior to December 31,
1998, the Company received $30,744 from stockholders related to the approved
share issuances. The advance payment was recorded as "advance from
stockholders," a separate component of stockholders' equity, on the balance
sheet as of December 31, 1998.
 
  (b) Distribution of earnings
 
     In accordance with ROC Company Law, the Company's articles of incorporation
stipulate that 10% of annual earnings (net of losses of prior years, if any) is
to be retained as statutory reserve until such retention equals the amount of
issued share capital. The distribution of remaining earnings should be proposed
by the board of directors and decided in a stockholders meeting. At least 0.01%
of the distribution should be appropriated as employees' bonuses when the
stockholders approve an earnings distribution. Future dividends will be
distributed in NT dollars.
 
  (c) Accumulated deficit
 
     According to the ROC Company Law, if accumulated deficit is over one-half
of the common stock, the board of directors shall convene a meeting of
stockholders and make a report on such loss.
 
(12) INCOME TAXES
 
     The Company's earnings are subject to an income tax rate of 20%. For the
years ended December 31, 1998, 1997 and 1996, income tax expense (benefit) was

     A valuation allowance has been established at December 31, 1998 and 1997
due to the uncertainty of realizing a portion of the deferred tax asset balance.
In management's opinion it is more likely than not that the net deferred tax
asset balance at December 31, 1998 and 1997 will be realized.
 
     The significant factors considered in determining the valuation allowance
at December 31, 1998 and 1997 included the Company's eight year financial
forecast, the expected length of the Company's start-up period for its newly
constructed facilities, the expected future market conditions in Taiwan and the
semiconductor industry, the impact of the tax holiday periods, and the
expiration dates of available investment tax credits and loss carryforwards. The
Company increased its valuation allowance by approximately $30 million as of
December 31, 1998 as compared to December 31, 1997 primarily due to a change in
market conditions which resulted in a significant reduction in the Company's
near-term taxable income forecast.
 
     According to the ROC Income Tax Law, pre-operating expenses of the Company
during the development stage are amortized for tax purposes on a straight-line
basis over a period of not less than five years.
 
     ROC tax regulations stipulate that investment tax credits used by the
Company each year shall not exceed 50% of the current income tax payable, and
any unused balance can be carried forward to the following four years, subject
to the same percentage limitation for each year except in the year of expiration
when any remainder can be used for offset of income tax payable in that year. As
of December 31, 1998, the estimated unused income tax credits, resulting from
investment in machinery and equipment and research and development, available to
reduce future tax liabilities and the years of expiration were as follows:

technology-based industry" as defined by the Statutes.
 
     According to the Statute for the Establishment and Administration of
Science-Based Industrial Park, a science-based industry may, within two years
from the date on which it begins to sell its products or to render services,
select any fiscal year in the four-year period from such date for exemption from
profit-seeking enterprise income tax for a period of five consecutive years from
the starting date of such fiscal year.
 
     In accordance with Article 8 of the Statute for Promotion of Upgrading

project) is entitled to enjoy both the tax holiday and shareholders investment
tax credit incentive schemes. The Company has chosen January 1, 2000 as the tax
holiday starting date.
 
     The Company's subsequent expansion of NT$200,000 capital expenditure
project (phase II project) can only apply one of the above incentive schemes.
The stockholders' meeting on May 22, 1998 has selected to enjoy shareholders
investment tax credit.
 
     Pursuant to the ROC Income Tax Law, the Company's tax losses may be carried
forward for up to five years to reduce future taxable income. As of December 31,
1998, the estimated tax loss carryforwards were as follows:

  (b) Technical service agreement
 
     In accordance with a technical assistance agreement between the Company and
MEMC, the Company is required to pay MEMC fixed payments and the timing of such
payments is based on reaching certain milestones. As of December 31, 1998 and
1997, the remaining balance of such payments to be paid under the agreement
amounted to $834 and $2,500, respectively.
 
     In addition, the Company pays MEMC an annual royalty based on net sales and
operating income.
 
  (c) Purchase of equipment
 
     As of December 31, 1998 and 1997, the Company had outstanding letters of
credit amounting to approximately $4,906 and $3,242, respectively, and was
committed to purchase equipment with a total estimated cost of $981 and $15,369,
respectively.
 
  (d) Syndicated term loan agreement
 
     The Company entered into certain syndication loan agreements with ABN AMRO
Bank and seven other banks (the "Banks") for the Company's Phase I and II
planned expansion. In accordance with the syndication loan agreements, the Banks
granted credit facilities to the Company for the purchase of machinery and
equipment. The commitment fee is charged at a certain rate per annum payable
quarterly, based on the committed-to withdraw but unborrowed balance, if any.
Commitment fees paid for the years ended December 31, 1998 and 1997 amounted to
$9 and $44, respectively.
 
(15) RECONCILIATION TO UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
 
     The Company's financial statements have been prepared in accordance with
ROC GAAP. ROC GAAP vary in certain significant respects from US GAAP.
Differences which have a significant effect on the Company's results of
operations and stockholders' equity are as follows:
 
  (a) Employee retirement benefits
 
     Prior to January 1, 1998, the pension expense recorded by the Company in
connection with its defined benefit pension plan was based on the amount of the
contributions made by the Company to the pension plan as required by government
regulations under ROC GAAP. As described in note 2(j), the Company began
recording pension expense using actuarial techniques as specified by ROC SFAS
No. 18 (ROC SFAS No. 18 is similar to US SFAS No. 87). Under US GAAP, the
accumulated pension obligation and pension expense is determined on an actuarial
basis, assuming the Company first adopted this policy at the beginning of 1997
 
                                      F-43

                    TAISIL ELECTRONIC MATERIALS CORPORATION
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
since it was not feasible to apply the actuarial basis at an earlier period. The
impact of this difference is not significant to the Company's determination of
results of operations or stockholders' equity under US GAAP for the periods
presented.
 
  (b) Technology fee
 
     Under ROC GAAP, the Company capitalizes and amortizes certain costs in
connection with a technical assistance agreement entered into with a
shareholder, MEMC. Under US GAAP, such payments are expensed as incurred or
treated as a deemed dividend depending on the nature of the payment. In 1998,
the Company made a royalty payment of $1,666 which was treated as a deemed
dividend.
 
     A reconciliation from ROC GAAP to US GAAP of net loss and stockholders'
equity are as follows:

     14.01 - In the event that PHC is in default with respect to any payments
required pursuant to this Agreement, MEMC may give written notice to PHC,

supply further information or services pursuant to this Agreement, and all of
the rights and licenses granted to PHC pursuant to ARTICLE IV of this Agreement.
MEMC's right to terminate pursuant to this Section 14.01 shall be at the option
of MEMC and shall not constitute a waiver of its other rights or remedies with
respect to said default, and the failure to exercise any such right in the event
of any occurrence giving rise thereto, shall not constitute a waiver of the
right in the event of any subsequent occurrence.

     In the event of termination of this Agreement by MEMC under this Section
14.01, then PHC agrees to return to MEMC originals and copies of all portions of
any notes, reports, photographs, manuals, memoranda, plans, drawings, flow

          b)   that MEMC shall not be in default under the Joint Venture
               Agreement.

Termination by MEMC pursuant to the provisions of this Section 14.02 shall not
act to terminate rights and licenses already granted pursuant to this Agreement
prior to the effective date of such termination, provided however, such rights
and licenses shall be non-exclusive.

     14.03 - It is understood that, in case of failure of the negotiations under
Section 3.05 of this Agreement, this Agreement shall expire five (5) years after
the Date of First Commercial Production, and such expiration shall not act to
terminate rights and licenses already granted pursuant to this Agreement,
provided however, such rights and licenses shall be non-exclusive.

     14.04 - If either party shall be in default of any obligation hereunder of
a substantial nature and if such party shall fail to remedy such default within
sixty (60) days after written notice thereof, any non-defaulting party hereto

termination to the other party given at any time within ninety (90) days after
said sixty (60) days. Such termination shall be in addition to any other rights
or remedies which may exist on account of such default.

     14.05 - Termination pursuant to this ARTICLE XIV and expiration pursuant to
Section 14.03 of the rights and obligations specified therein shall not
terminate any of the obligations of PHC, including the obligation to pay in full

the expiration of this Agreement and the obligation of PHC to observe the
confidentiality provisions set forth in ARTICLE VI of this Agreement. It is

     (as so amended, the "Agreement").

B.   MEMC and PHC wish to further amend the Agreement as set forth below.

     NOW, THEREFORE, pursuant to Section 17.03 of the Agreement, the parties
agree as follows:

1.   Limitation of Scope. The following sentence shall be added at the end of
     the definition of Silicon Wafers in Section 1.02:

     "As used herein,  Silicon Wafers shall mean [CONFIDENTIAL MATERIAL HAS BEEN
     DELETED AND FILED SEPARATELY WITH THE SEC]."

2.   Research and Development Projects. Add the following paragraphs at the end
     of Section 3.01 as follows:

     "During the Term of the Agreement, the parties shall meet no less
     frequently than annually at a mutually agreeable time and place at which
     MEMC shall advise PHC of the nature of any major research or pilot plant
     projects within the Field of this Agreement which MEMC is undertaking. In
     addition, during the Term of the Agreement, MEMC shall periodically advise
     PHC of the status and progress of projects in the Field of the Agreement
     which MEMC has undertaken via its "Product and Process Pipeline" program
     (the program under which MEMC currently directs its research and
     development activities) or any similar successor program.

     During the Term of this Agreement, if PHC requests information regarding a
     technical improvement or development of MEMC (either product or
     process-related) within the Field of the Agreement and PHC and MEMC agree
     that PHC has a commercial requirement for such information, then MEMC will
     make available to PHC the necessary technical information if MEMC has
     incorporated the improvement or development into any of its Plants. If MEMC
     has not incorporated the improvement or development into any of its Plants,
     the parties will either agree for MEMC to transfer the information to PHC
     at a later stage of development or for PHC to participate in the
     development. PHC may undertake its own research or pilot plant projects
     provided such projects (i) are not duplicative of any MEMC projects, (ii)
     are mutually beneficial, and (iii) are agreed upon by both parties."

3. Licenses to MEMC.

     (a)  Sections 4.03 and 4.04 are deleted in their entirety and the following
          sections are added to the Agreement:

          "4.03 - PHC agrees to grant and hereby grants to MEMC a worldwide,
          royalty-free, nonexclusive right and license, with the right to
          sublicense, to use all Technical Information which PHC supplies to
          MEMC pursuant to this Agreement.

          4.04 - PHC agrees to grant and hereby grants to MEMC a royalty-free,
          nonexclusive right and license, with the right to sublicense, under
          and for the full terms of all PHC Korean Patents. PHC agrees to grant
          and hereby grants to MEMC a royalty-free, exclusive right and license,
          with the right to sublicense, under and for the full terms of all PHC
          Ex-Korean Patents; provided, that the parties agree that PHC shall
          retain the right to use (but not license) the PHC Ex-Korean Patents.

          4.05 - Notwithstanding the foregoing, MEMC shall be permitted to
          sublicense PHC Technical Information or patents to its Affiliates or
          MEMC Joint Ventures only if the Affiliate or MEMC Joint Venture grants
          to PHC a royalty-free license to its Technical Information and patents
          in the Field of the Agreement which such Affiliate or MEMC Joint
          Venture has the legal right to grant. Any license from an MEMC
          Affiliate or MEMC Joint Venture shall be on the same terms as the MEMC
          licenses granted in Sections 4.01 and 4.02 hereof."

     (b)  New Sections 1.18, 1.19 and 1.20 are added as follows:

          "1.18 - "MEMC Joint Ventures" means joint venture companies in which

          engaged in the manufacture and/or sale of silicon wafers.

          1.19 - "PHC Korean Patents" shall have the meaning set forth in
          Section 18.01 hereof.

          1.20 - "PHC Ex-Korean Patents" shall have the meaning set forth in
          Section 18.02 hereof."

          following:

          5.02 and elsewhere in this Agreement, during the Term of this
          Agreement, PHC shall pay MEMC a running royalty consisting of (i)
          [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED SEPARATELY WITH THE
          SEC] of Net Sales Proceeds (the "Net Sales Royalty"), and (ii)
          [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED SEPARATELY WITH THE
          SEC] of Net Income After Taxes (the "NIAT Royalty")."

     (b)  The first sentence of Section 5.06 is deleted in its entirety and
          replaced with the following:

          "5.06 - The Net Sales Royalty due MEMC pursuant to this Agreement
          shall be computed quarterly and shall be paid to MEMC within sixty
          (60) days of the last day of March, June, September, and December of
          each calendar year; each such payment shall be accompanied by a
          written report setting forth the quantities and descriptions of all
          Silicon Wafers sold by PHC during the period for which payment is
          made; the NIAT Royalty shall be computed annually and shall be paid to
          MEMC within sixty (60) days of the last day of each calendar year;
          each such payment shall be accompanied by an earnings statement of PHC
          detailing the calculation of Net Income After Taxes."

     (c)  In the last sentence of Section 5.06, the phrase "or annual, as the
          case may be" is inserted after the word "quarterly".

     (d)  In the second sentence of Section 5.07, the phrase "or year, as the
          case may be" shall be added after the phrase "calendar quarter".

          taxes but before deduction of the NIAT Royalty and shall be computed
          in accordance with U.S. generally accepted accounting principles.

5. Sharing of Certain MEMC Royalties.

     (a)  A new Section 5.08 is added as follows:

          "5.08 - In the event that MEMC sublicenses any patent jointly owned by
          the parties or owned or controlled solely by PHC to a third party
          other than (i) an MEMC Affiliate, or (ii) an MEMC Joint Venture, in
          consideration for cash royalties, PHC shall be entitled during the
          Term of this Agreement to a share of the royalties as agreed between
          the parties. In determining PHC's share of the royalties, the parties
          shall take into consideration each party's relative contribution to
          the sublicensed technology, and MEMC's contribution to the core
          technology on which the sublicensed technology is based or to which it
          is related. If the parties are unable to agree on PHC's share of the
          royalties, the matter shall be submitted to arbitration as set forth
          in Section 13.04 below."

6.   Running Royalty Upon Termination

     (a)  A new Section 5.09 is added as follows:

          "5.09 - Following termination or expiration of this Agreement, PHC
          shall pay MEMC, in accordance with the procedures set forth in this
          Article V, a running royalty as follows:

               a. For the [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED
          SEPARATELY WITH THE SEC] following termination or expiration, a
          percentage Net Sales Royalty and NIAT Royalty equal to [CONFIDENTIAL
          MATERIAL HAS BEEN DELETED AND FILED SEPARATELY WITH THE SEC] of the
          percentage Net Sales Royalty and NIAT Royalty, respectively, in effect
          at the date of termination or expiration;

               b. For the [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED
          SEPARATELY WITH THE SEC] following termination or expiration, a
          percentage Net Sales Royalty and NIAT Royalty shall be equal to
          [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED SEPARATELY WITH THE
          SEC] of the percentage Net Sales Royalty and NIAT Royalty,
          respectively, in effect at the date of termination or expiration; and

               c. For the [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND FILED
          SEPARATELY WITH THE SEC] following termination or expiration, a
<PAGE>   3

          percentage Net Sales Royalty and a NIAT Royalty equal to [CONFIDENTIAL
          MATERIAL HAS BEEN DELETED AND FILED SEPARATELY WITH THE SEC] of the
          percentage Net Sales Royalty and NIAT Royalty, respectively, in effect
          at the date of termination or expiration.

               d. Thereafter, PHC shall have no obligation to pay any royalty
          whatsoever to MEMC."

     (b)  The following phrase is added at the end of the first sentence of
          Section 14.05:

          "and the obligation of PHC to pay MEMC a running royalty upon
          termination or expiration of this Agreement as set forth in Section
          5.09"

7.   Notice

     In Sections 12.01 and 12.02, "telex or facsimile" shall be replaced with
     "telex, facsimile, or electronic mail."

8.   Arbitration of Certain Matters

     (a)  The following phrase shall be added at the beginning of the first
          sentence of Section 13.01:

          "Except for those  matters which are to be settled by  arbitration  in
          accordance with Section 13.04 below,"

     (b) A new Section 13.04 is added as follows:

          "13.04 - Arbitration to determine PHC's share of royalties received by
          MEMC pursuant to Section 5.08 shall be by a single arbitrator pursuant
          to the Rules of Conciliation and Arbitration of the International
          Chamber of Commerce (the "Rules") then in force. The single arbitrator
          shall be selected by the parties and shall be a person familiar with
          the silicon wafer business. If the parties are unable to agree upon an
          arbitrator within thirty (30) days after arbitration is invoked,
          either party may ask the ICC to appoint an arbitrator subject to the
          following stipulation: if PHC so requests, the arbitrator shall not be
          a U.S. national and, if MEMC so requests, the arbitrator shall not be
          a Korean national. The arbitration shall be conducted in Singapore.
          Each party shall submit its position to the arbitrator and the
          arbitrator shall agree upon and approve one of the positions
          submitted. Unless otherwise agreed by the parties, the arbitration
          proceedings shall be conducted in English and any relevant documents
          in other languages shall be translated into English at the expense of
          the party producing them. In rendering its decision, the arbitrator
          shall apply the terms and conditions of this Agreement. The arbitrator
          shall determine how the expenses of the arbitration are to be borne by
          the parties in dispute."

9.   Term of Agreement

     (a)  Section 14.03 is deleted in its entirety and replaced with the
          following:

          "14.03 - No later than [CONFIDENTIAL MATERIAL HAS BEEN DELETED AND
          FILED SEPARATELY WITH THE SEC] after the effective date of this Third
          Amendment, MEMC and PHC shall negotiate in good faith on another
          technical agreement with the object of allowing PHC and MEMC to obtain
          continuing technology from the other party on reasonable terms. In the
          case of failure of such negotiations and unless terminated earlier as
          herein provided, this Agreement shall expire [CONFIDENTIAL MATERIAL
          HAS BEEN DELETED AND FILED SEPARATELY WITH THE SEC] from the effective
          date of this Third Amendment. Expiration or termination of this
          Agreement shall not act to terminate any of the rights or licenses
          granted by the parties hereunder, provided, however, that all rights
          and licenses granted by MEMC to PHC shall be non-exclusive. The period
          prior to the expiration or termination of this Agreement is herein
          referred to as the "Term of the Agreement.""

     (b)  In Section 3.02, the phrase "during the five (5) year period beginning
          with the Date of First Commercial Production" shall be replaced with
          "during the Term of this Agreement."

     (c)  In Section 3.04, the phrase "During the five (5) year period following
          the Date of First Commercial Production" shall be replaced with
          "During the Term of this Agreement".

10.  Management of PHC and Jointly-Owned Patents. A new Article XVIII-Management
     of PHC and Jointly-Owned Patents is added with the following provisions:

     "18.01 - In the Republic of Korea, PHC shall be responsible for preparing,
     filing, prosecuting and maintaining patents and patent applications which
     claim as an invention a PHC development ("PHC Korean Patents").

     18.02 - In countries other than the Republic of Korea, MEMC shall be
     responsible, upon the request of and at the expense of PHC, for preparing,
<PAGE>   4

     filing, prosecuting and maintaining patents and patent applications which
     claim as an invention a PHC development ("PHC Ex-Korean Patents"). The
     decision of when and where to file PHC Ex-Korean Patents and what other
     actions to take with respect thereto shall be agreed between the parties;
     provided, that if PHC elects not to pay for any filing or action proposed
     by MEMC with respect to a PHC Ex-Korean Patent and MEMC makes such filing
     or takes such action at its expense, PHC agrees that it will assign its
     entire right and interest in and to such patent or patent application to
     MEMC. MEMC shall keep PHC advised as to all developments with respect to
     PHC Ex-Korean Patents and shall endeavor to supply PHC copies of all papers
     received and filed in connection with the prosecution thereof and give due
     consideration to PHC's comments thereon. If PHC requests MEMC to prepare,
     file, prosecute or maintain a PHC Ex-Korean Patent and MEMC elects not to
     assume or continue responsibility for such actions, PHC may take such
     actions at its own expense. In such event, the exclusive license granted to
     MEMC with respect to such patent shall become nonexclusive.

     18.03 - All patents and patent applications which claim as an invention a
     joint development of PHC and MEMC shall be filed in the names of and be
     jointly owned by PHC and MEMC. MEMC shall be solely responsible for
     preparing, filing, prosecuting and maintaining such patents and patent
     applications. The expenses of such actions shall be shared equally by PHC
     and MEMC. MEMC shall have the right to freely sublicense any of such
     jointly-held patents; provided, that in the Republic of Korea, PHC's
     consent shall be required for any such sublicense. Elsewhere, if PHC's
     consent is legally required prior to MEMC's grant of a sublicense, then PHC
     agrees that it shall provide such consent. PHC shall have the right to
     sublicense any of such jointly-held patents with the consent of MEMC. MEMC
     shall notify PHC in writing prior to granting a sublicense of any
     jointly-held patent."

11.  Effect

     This Third Amendment shall become effective on October 1, 1998 and shall
supercede any provisions of the Agreement which are in conflict with this
Amendment. All other provisions of the Agreement shall remain effective and
binding.

     IN WITNESS WHEREOF, the parties have executed this Third Amendment as
follows:

                         MEMC ELECTRONIC MATERIALS, INC.

                        SPECIAL INCENTIVE BONUS AGREEMENT


     THIS  AGREEMENT is entered into between  MEMC  Electronic  Materials,  Inc.
("MEMC") and John P. De Luca ("Employee").

     Employee is employed by MEMC.

     MEMC recognizes the value of the services performed by Employee and wishes
to encourage Employee to continue employment with MEMC. Employee wishes to be
paid a certain amount of additional compensation in return for continuous
employment with MEMC for a designated period of time.

     NOW, THEREFORE, in consideration of the mutual promises contained in this
Agreement, the parties agree as follows:

     1. Nature of Contract. This Agreement provides for an additional bonus (the
"Special Incentive Bonus") to be paid by MEMC to Employee in consideration for
Employee's continuous employment throughout the period of April 1, 1998 through
June 30, 1999 (the "Retention Period").

     Nothing contained in this Agreement shall be construed to be a contract of
employment for any term, nor as conferring upon Employee the right to continue
in the employment of MEMC in Employee's present capacity or in any other
capacity. Nothing contained in this Agreement shall be construed to preclude
either party from terminating the employment relationship at any time.

     It is expressly understood by the parties that this Agreement relates
exclusively to additional compensation for Employee's services and is not
intended to be the entire employment contract. This Agreement merely supplements
Employee's employment contract with MEMC.

     The Special Incentive Bonus provided by this Agreement is in addition to
the cash compensation and other fringe benefits provided to Employee pursuant to
any plan or plans maintained by MEMC for its employees generally.

     2. Special Incentive Bonus. If Employee remains in the employment of MEMC
continuously throughout the Retention Period of April 1, 1998 through June 30,
1999, Employee shall be entitled to a Special Incentive Bonus in the amount of
$250,000.

     3. Terms of Payment. Fifty percent of the Special Incentive Bonus will be
payable with the March 31, 1998 payroll (the "Advance Payment"); the remaining
fifty percent of the Special Incentive Bonus will be payable with the June 30,
1999 payroll (the "Final Payment").

     Subject to the exceptions below, in the event Employee terminates
employment with MEMC before April 1, 1999, Employee shall reimburse MEMC the
entire amount of the Advance Payment (including any payroll tax withheld).

     Subject to the exceptions below, in the event Employee terminates
employment with MEMC after March 31, 1999 and before July 1, 1999, Employee
shall reimburse MEMC that portion of the Advance Payment (including any payroll
tax withheld) that the number of days in the period beginning on the date of
Employee's termination of employment with MEMC and ending on June 30, 1999 bears
to 456. For example, if Employee terminates employment with MEMC on June 1,
1999, Employee shall reimburse MEMC 30 / 456 (or 6.58%) of the Advance Payment.

     No reimbursement of the Advance Payment shall be required in the event of
the death or total and permanent disability of Employee, or in the event
Employee's employment with MEMC is involuntarily terminated by MEMC as a result
of a change in control of MEMC or a reduction in the workforce of MEMC. The
reimbursement as described above shall be required in the event of Employee's
termination of employment with MEMC for any other reason.

     In no event shall Employee be entitled to the Final Payment in the event of
Employee's termination of employment with MEMC for any reason before July 1,
1999.

     4. Tax Withholding

     MEMC shall withhold from the Special Incentive Bonus the amount necessary
to enable MEMC to remit to the appropriate government entity or entities the
amount required to be withheld from wages with respect to such payments. All
references to the Special Incentive Bonus, the Advance Payment, and the Final
Payment shall mean the gross amount of such amount before such payroll taxes are
withheld.

     5. Collection of Reimbursement

     Employee agrees that any reimbursement of the Advance Payment due MEMC in
the event of termination of employment of the Employee before July 1, 1999 may
be withheld by MEMC from any amounts owed by MEMC to Employee.

     6. Confidentiality

     Employee agrees that the terms of this Special Incentive Bonus Agreement
<PAGE>   2

are confidential and will not be discussed with or disclosed to any present or
former employee of MEMC or its affiliates or subsidiaries.

     7. Governing Law

     The interpretation and enforcement of this Agreement shall be governed by
the laws of the State of Missouri.

     Employee acknowledges that this Agreement has been reviewed in detail by
Employee and that Employee voluntarily entered into this Agreement.

     IN WITNESS WHEREOF, the parties have executed this Special Incentive Bonus
Agreement this 24th day of March, 1998.

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

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED WITH YEAR ENDED DECEMBER 31, 1997

NET SALES. Net sales decreased by 23.1% to $758.9 million for 1998 from $986.7
million for 1997, due to significant declines in the price for silicon wafers
and a 14.3% decrease in product volumes somewhat offset by an improved product
mix. The decline in price during 1998 is primarily attributable to significant
excess capacity in the silicon wafer industry and continuing pricing pressure
from customers who are experiencing reduced profitability or losses due to
significant excess capacity and price erosion in the semiconductor industry. The
decrease in product volume in 1998 was principally due to the weak economic
conditions in the Asia Pacific markets brought on by the Asian financial crisis
and the continuing recession in Japan coupled with semiconductor customers
shrinking the size of their devices (requiring less silicon per device). A
concerted effort by customers to use fewer test/monitor wafers also caused
product volumes to decline in 1998. This marks the first year since 1985 that
product volumes for the silicon industry have not increased year over year.
Advanced large diameter and epitaxial products represented 47.1% of product
volume for 1998 compared to 39.1% for 1997. While both 200 millimeter and
epitaxial product volumes grew during 1998, the increase in this ratio is
primarily indicative of customers utilizing 200 millimeter wafers in preference
to smaller diameter wafers in order to obtain the lowest cost per device. While
product volume declined in total by 14.3% during 1998, 200 millimeter product
volume grew by 12.3%.

MEMC operates in all major semiconductor-producing regions of the world, with
almost half of the Company's 1998 net sales to customers located outside North
America. Net sales to North America decreased 21.7% and comprised 51.4% of 1998
sales compared to 50.4% of 1997 sales, led by a fall in prices and product
volume, partially offset by improved product mix. Lower prices offset by an
improved product mix and higher volumes combined to result in a 10.1% decrease
in net sales to Europe, which constituted 23.4% of 1998 sales compared to 20.0%
of 1997 sales. Net sales to Japan decreased 22.6% and comprised 15.7% of 1998
sales compared to 15.6% of 1997 sales, as lower volumes and prices more than
offset an improved product mix. Declines in product volumes, prices and product
mix resulted in a decrease of 47.5% in net sales to Asia Pacific, which
comprised 9.5% of 1998 sales compared to 13.9% of 1997 sales. See Note 17 of
Notes to Consolidated Financial Statements herein.

GROSS MARGIN. The lower volumes experienced in 1998 decreased the capacity
utilization and, coupled with the lower selling prices, caused gross margins to
decrease to a negative 4.2% for 1998 from the 12.6% achieved in 1997. Despite
the benefits from the mix improvement and cost cutting measures that were
implemented during 1998, the volume decreases and price pressures began early in
the year and resulted in negative margins. These cost-cutting initiatives
included short-term plant shutdowns, implementing the Company's "best practices"
worldwide, implementing a plant focus program that limits the number of wafer
diameters manufactured at each site, and working with our suppliers to create
cost reduction opportunities and price reductions. In addition, the Company
reduced its workforce by approximately 1,700 employees, or 21.3%, compared to
December 31, 1997. 

MARKETING AND ADMINISTRATION. Marketing and administration expenses increased 
4.0% and represented 9.7% of net sales for 1998 compared to 7.2% for 1997. The
increase is predominately attributable to expenses incurred for business systems
redesign in anticipation of implementing SAP worldwide and fees related to
several other initiatives completed during the year.

RESEARCH AND DEVELOPMENT. Research and development costs rose 26.6% and
represented 10.8% of net sales for 1998 compared to 6.5% for 1997. The increase
in research and development costs is attributable to continuing investments in
300 millimeter wafer development and depreciation associated with capital
expenditures made for the 300 millimeter pilot line in St. Peters, Missouri and
the 300 millimeter integrated development line in Utsunomiya, Japan.

RESTRUCTURING COSTS. During the second quarter of 1998, the Company decided to
close its small diameter wafer facility in Spartanburg, South Carolina and to
withdraw from the Company's joint venture in a small diameter wafer operation in
China. These actions were taken because (1) a number of semiconductor
manufacturers have been running their larger diameter manufacturing lines in
preference to their small diameter lines in order to


                                       13
<PAGE>   3

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

gain production efficiencies; (2) a number of semiconductor manufacturers
recently have undertaken restructuring initiatives focused on permanently
eliminating small diameter lines; and (3) management believes that small
diameter wafer capacity will exceed demand even after the semiconductor industry
begins to recover. The Company also decided to forego construction of a new 200
millimeter wafer facility at its joint venture in Malaysia. This decision was
based upon current and anticipated excess capacity for 200 millimeter wafers and
the significant price erosion that the Company has experienced for these wafers.

These actions resulted in a charge to operations of $121.7 million, comprised of
$81.3 million non-cash asset impairments/write-offs, $25.9 million in
dismantling and related costs and $14.5 million in personnel related costs. The
assets for which an impairment loss has been recorded or which have been or will
be written-off are primarily property, plant and equipment which cannot be sold
or used at other Company facilities. In addition, the Company wrote-off
architectural design and site preparation fees as well as costs incurred to
develop a computer-integrated manufacturing system for the Malaysian joint
venture.

Personnel costs represent the expected cost of involuntary terminations for
approximately 600 hourly and salaried employees whom the Company does not expect
to relocate elsewhere within the organization. See Note 5 of Notes to
Consolidated Financial Statements herein. The Company also recorded a $24.6
million charge for a voluntary severance program for approximately 600 hourly
and salaried U.S. employees. Substantially all this amount was paid to employees
as of December 31, 1998.

Ongoing operating expenses until plant closure associated with the Spartanburg
facility of approximately $7.9 million will continue to be recorded as period
costs. Costs of approximately $8.2 million relating to the relocation and
installation of equipment from the Spartanburg facility to other sites will be
capitalized as incurred.

The Company estimates pre-tax savings from these restructuring activities and
the voluntary severance program to be approximately $60 million on an annualized
basis. Approximately half of these expected savings relate to the voluntary
severance program. As employees who participated in the voluntary severance plan
were no longer employed by the Company as of June 30, 1998, these savings began
to be realized in the third quarter of 1998.

The remaining $30 million in annualized savings principally relates to the
closure of the Company's Spartanburg facility. Approximately half of these
expected savings relate to personnel costs and the other half relate to
manufacturing costs such as depreciation and supplies and utilities which will
not be duplicated when Spartanburg's silicon wafer production is transferred to
another Company location. As the Company re-qualifies and transfers the
production of silicon wafers made at the Spartanburg facility to other Company
locations, it will reduce its Spartanburg workforce. With each workforce
reduction, the Company expects a portion of the annualized cost savings
associated with personnel costs to be realized and to a much lesser extent
manufacturing costs. As a result, a portion of the remaining $30 million in
annualized cost savings began to be realized in the third quarter of 1998 and is
expected to grow as workforce and production at the Spartanburg facility are
reduced. On an annualized basis, the Company estimates that approximately $9.0
million in savings began to be realized by December 31, 1998 related to the
closure of the Spartanburg facility. Because the manufacturing cost savings are
fixed in nature, they will largely be realized upon the closure of the
Spartanburg facility. While the Company believes that this will occur by April
30, 1999, the ability to re-qualify silicon wafers is highly dependent upon the
cooperation of the Company's customers.

INTEREST EXPENSE. Interest expense increased to $45.8 million for 1998 from
$14.7 million for 1997. The increase in interest expense is primarily
attributable to increased borrowings, and to a lesser extent the completion of
projects for which interest expense could no longer be capitalized. In addition,
the interest rates on the Company's loan agreements with its principal lender
were increased as a result of a debt re-negotiation during September 1998, as
described in Liquidity and Capital Resources below. Total debt was $909.8
million and $632.5 million at December 31, 1998 and 1997, respectively.

OTHER, NET. Other, net decreased to $1.0 million in expense for 1998 from $4.1
million of income for 1997, primarily due to the sale of the Company's Santa
Clara wafer facility in May 1997 that resulted in a pre-tax gain of $6.0
million.

INCOME TAXES. The effective income tax rate was 24.0% for 1998, as compared to
(26.8%) for 1997. This fluctuation is the result of changes in the composition
of worldwide taxable income, restructuring costs, non-


                                       14
<PAGE>   4

deductible operating expenses at the Company's Malaysian and Chinese joint
ventures, the establishment of valuation allowances on certain deferred tax
assets in Japan and certain foreign tax credit elections.

EQUITY IN INCOME (LOSS) OF JOINT VENTURES. Equity in income (loss) of joint
ventures decreased $49.0 million to a loss of $43.5 million in 1998 from $5.5
million in income in 1997. POSCO Huls Co., Ltd. (PHC), the Company's 40%-owned,
unconsolidated joint venture in South Korea, experienced a 28.0% decrease in
product volume and significantly lower prices resulting in lower sales
throughout 1998. While the reasons for the decline in prices are similar to
those of the Company, product volume declines were primarily the result of
excess capacity within the DRAM (memory) industry and efforts by Korean DRAM
manufacturers to reduce their production, thereby reducing the worldwide
oversupply, and shrink the size of their devices. For the year, PHC contributed
losses of $17.8 million compared to $11.1 million in income for 1997.

Net sales for Taisil Electronic Materials Corporation (Taisil), the Company's
45%-owned, unconsolidated joint venture in Taiwan, decreased slightly due to
significantly lower prices, which were partially offset by a 40.9% increase in
product volumes. The higher product volumes were primarily attributable to
obtaining additional customer qualifications during 1998. In addition, the
Taiwanese semiconductor market, particularly the foundry market, grew during
1998. During 1998, Taisil also made adjustments to its deferred tax valuation
allowance in recognition of changes in expected realization of its operating
loss carryforwards, of which the Company's share was $6.0 million. For the year,
Taisil contributed losses of $25.7 million in 1998 compared to $5.6 million in
losses for 1997.

NET LOSS. The decrease in net sales, restructuring costs, higher research and
development costs and interest expense, and the equity in loss of joint ventures
resulted in a net loss of $316.3 million for 1998 compared to $4.5 million for
1997. Management expects some reduction in losses in the first quarter of 1999,
as a result of the restructuring and cost-cutting actions, as well as
anticipated higher product volumes. Due to overcapacity and decreasing prices in
the semiconductor and silicon wafer industries, weak economic conditions in the
Asia Pacific region and Japan, and other factors, while the Company will
continue its significant performance improvements and cost-cutting efforts,
management does not expect the Company to be profitable in 1999. 

YEAR ENDED DECEMBER 31, 1997 COMPARED WITH YEAR ENDED DECEMBER 31, 1996

NET SALES. Net sales decreased by 11.9% to $986.7 million for 1997 from $1.1
billion for 1996, due to a 5.1% decrease in product volume and a decline in
price somewhat offset by an improved product mix. Overcapacity, inventory
reduction and weak pricing in the semiconductor industry, particularly for the
DRAM market, led to reduced orders for silicon wafers that began in the second
half of 1996 and gradually recovered throughout 1997. In addition, the Company
and its competitors expanded at a faster rate than silicon consumption growth
during 1997, resulting in overcapacity in the silicon wafer industry. The
combination of these market conditions led to significant price reductions
throughout 1997. Advanced large diameter and epitaxial products represented
39.1% of product volume for 1997 compared to 36.7% for 1996.

Net sales to North America decreased 12.5% and comprised 50.4% of 1997 sales
compared to 50.8% of 1996 sales led by a fall in prices and, to a lesser extent,
volume, partially offset by improved product mix. Lower prices and volume, a
less favorable product mix and the general weakening of European currencies
relative to the U.S. dollar throughout 1997 combined to result in a 22.8%
decrease in net sales to Europe, which constituted 20.0% of 1997 sales compared
to 22.9% of 1996 sales. Net sales to Japan increased by 21.0% and comprised
15.6% of 1997 sales compared to 11.4% of 1996 sales as higher volume from
expanded manufacturing capacity and improved product mix more than offset lower
pricing and the weakening of the Japanese yen relative to the U.S. dollar
throughout 1997. The Asia Pacific market experienced similar declines in
pricing, volume and product mix as did other geographic markets served by the
Company. Net sales to Asia Pacific decreased 17.9% and comprised 13.9% of 1997
sales compared to 14.9% of 1996 sales. Product volume also declined due to the
continued shift in sales from the Company to PHC and Taisil.

GROSS MARGIN. Gross margin as a percentage of net sales decreased to 12.6% in
1997 from 22.3% in 1996. Lower pricing and capacity utilization more than offset
the slight improvement in product mix during 1997. The Company also completed
the construction of its 200 millimeter silicon wafer facility at MEMC Southwest
(the Company's 80%-owned joint venture in Sherman, Texas) and the expansion of
its 200 millimeter epitaxial wafer facility in St. Peters which resulted in
higher levels of training and start-up costs and contributed to the lower


                                       15
<PAGE>   5
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

capacity utilization. However, these expansions, which are dedicated to the
production of 200 millimeter product, position the Company to respond to the
demand for this diameter wafer, which analysts estimate grew approximately 28%
industry wide in 1997.

MARKETING AND ADMINISTRATION. Marketing and administration expenses declined
11.3% and represented 7.2% of net sales for 1997 compared to 7.1% for 1996. The
decrease is predominately attributable to a reduction in incentive compensation.

RESEARCH AND DEVELOPMENT. Research and development costs rose 45.5% and
represented 6.5% of net sales for 1997 compared to 4.0% for 1996. The increase
in research and development costs is attributable to the addition of engineering
and scientific personnel, the start-up of the 300 millimeter pilot line in St.
Peters and increased efforts in the areas of crystal technology, epitaxial
silicon research and the development of the 300 millimeter wafer.

INTEREST EXPENSE. Interest expense increased to $14.7 million for 1997 from $0.5
million for 1996 as outstanding debt rose, projects were completed and interest
costs were no longer capitalized. Total debt was $632.5 million and $331.8
million at December 31, 1997 and 1996, respectively.

OTHER, NET. Other, net improved to $4.1 million of income for 1997 from $7.4
million in expense for 1996, primarily due to the recognition of a $6.0 million
gain on the sale of its Santa Clara, California silicon wafer facility.

INCOME TAXES. Income tax expense was recorded for 1997 despite the recognition
of a pre-tax loss primarily due to the composition of the Company's worldwide
taxable income. The effective income tax rate for 1996 was 40.0%.

EQUITY IN INCOME OF JOINT VENTURES. Equity in income of joint ventures decreased
to $5.5 million in 1997 from $26.7 million in 1996. PHC recorded higher volumes
and net sales; however, the impact of lower prices, a less favorable product mix
and a work stoppage in the third quarter (and the subsequent ramp-up of
operations) resulted in significantly reduced gross margins. For the year, PHC
provided a contribution of $11.1 million compared to $34.1 million for 1996.
Following the start-up and qualification of its operations, Taisil was able to
generate net sales sufficient to keep pace with the increase in expenses as its
capacity expanded. As a result, the Company's share of Taisil's loss of $5.6
million in 1997 and $7.4 million in 1996 is fairly consistent.

NET EARNINGS (LOSS). Lower pricing and capacity utilization coupled with higher
start-up and training costs, research and development costs and interest
expense, and lower equity in income of joint ventures resulted in a net loss of
$4.5 million for 1997 compared to net earnings of $103.4 million for 1996.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1998, the Company had $16.2 million of cash and cash equivalents
compared to $30.1 million at December 31, 1997.

Cash flows from operating activities decreased to ($33.9) million for 1998 from
$29.4 million for 1997. This $63.3 million decline was largely attributable to
lower results from operations, an increase in deferred taxes, and a decrease in
accounts payable, partially offset by a decrease in accounts receivable and
inventories.

Accounts receivable of $98.5 million at December 31, 1998 decreased $56.2
million, or 36.3%, from $154.7 million at the end of 1997. This decrease is
consistent with the 40.5% decrease in fourth quarter sales between the two
years. Days' sales outstanding were 58.4 days at December 31, 1998 compared to
55.0 days at the end of 1997 based upon annualized fourth quarter sales for the
respective years. This increase is attributable to lengthier collection periods
in the Asian region in the fourth quarter of 1998.

Inventories declined $25.5 million, or 18.0%, from the prior year to $115.9
million at December 31, 1998. This decrease is primarily due to lower
anticipated sales in the first quarter of 1999 compared to the year-ago period
and a concerted effort by the Company to reduce raw materials and manage
inventory levels. Related inventory reserves for obsolescence, lower of cost or
market issues, or other impairments increased $11.7 million in 1998 to $19.6
million, as a result of declining sales and the resultant determination that
certain goods in process, finished goods and spare parts were no longer salable
or usable. Year-end inventories as a percentage of annualized fourth quarter
sales increased from 13.8% at the end of 1997 to 18.8% at December 31, 1998, as


                                       16
<PAGE>   6

a result of the significant sales decline in 1998 and the character of certain
inventory items such as spare parts which do not fluctuate with sales levels.

The Company's net deferred tax assets increased $99.1 million to $127.8 million
at December 31, 1998. Management believes it is more likely than not that, with
its projections of future taxable income and after consideration of the
valuation allowance, the Company will generate sufficient taxable income to
realize the benefits of the net deferred tax assets existing at December 31,
1998.

In order to realize the net deferred tax assets existing at December 31, 1998,
the Company will need to generate future taxable income of approximately $353
million. The Company's net operating loss (NOL) carryforwards total $410
million, of which $7 million will expire in 2001; $15 million will expire in
2002; $32 million will expire in 2003; $27 million will expire in 2012; and $329
million will expire in 2018. There can be no assurance, however, that the
Company will generate sufficient taxable income to realize the full benefit of
the existing net deferred tax assets.

Accounts payable decreased $33.6 million or 23.0% compared to the balance at the
end of 1997 due to a significant reduction in capital expenditures and lower
operating costs as a result of lower product volumes in the fourth quarter of
1998 compared to the year-ago period.

Capital expenditures decreased $177.8 million or 47.7% versus the prior year to
$194.6 million. The 1998 capital expenditures primarily consisted of equipping
the 300 millimeter pilot line in St. Peters, the 300 millimeter integrated
development line in Utsunomiya, the granular polysilicon expansion at MEMC
Pasadena and the installation of epitaxial reactors in Utsunomiya. The Company
anticipates that it will reduce capital expenditures in 1999 to less than $85.0
million. At December 31, 1998, the Company had $38.8 million of committed
capital expenditures related to the implementation of SAP worldwide and various
manufacturing and technology projects.

Equity infusions in joint ventures increased $14.9 million to $25.5 million for
1998 and related solely to Taisil. Although Taisil has not yet generated
positive net income, the Company does not consider its investment in Taisil to
be impaired as of December 31, 1998 based on the following factors: the level of
commitment by all of Taisil's shareholders; the growing Taiwanese silicon wafer
market; increased customer qualifications and associated increased product
volumes; and future anticipated positive operating cash flows.

At December 31, 1998, the Company maintained $927.2 million of committed
long-term loan agreements, of which $873.7 million was outstanding. The Company
also maintained $83.0 million of short-term lines of credit, of which $36.1
million was outstanding at year-end. The Company's weighted average cost of
borrowing was 7.8% at December 31, 1998.

Total debt outstanding increased to $909.8 million at December 31, 1998 from
$632.5 million at December 31, 1997. The total debt to total capital ratio at
December 31, 1998 was 67.0%.

During September 1998, the Company received a three-year $100.0 million
revolving credit facility from VEBA AG, the parent of the Company's majority
stockholder. This is in addition to a $50.0 million credit facility from VEBA AG
that was made available to the Company on June 30, 1998. VEBA AG and its
affiliates agreed to extend until 2001 all of the Company's outstanding debt
with VEBAAGand its affiliates maturing prior to January 1, 2001 (but only in the
event the Company has used its best efforts to obtain replacement financing on
equivalent terms).

As part of this agreement, the Company agreed to increase the interest rates
payable on the Company's outstanding debt with VEBA AG and its affiliates to
reflect interest rate spreads applicable to an average industrial borrower at a
specified credit rating. These higher rates, which are in part attributable to
extended terms, will result in an increase in interest expense of approximately
$15.0 million per year based upon $679.6 million of debt outstanding with VEBA
AG and its affiliates as of September 30, 1998. Prior to this debt
re-negotiation, interest rates on the U.S. dollar and Japanese yen based loans
outstanding with VEBA AG and its affiliates ranged from 2.1% to 7.6%. As a
result of this debt re-negotiation, these loans will now have interest rates
ranging from 3.4% to 10.2%. Additionally, all outstanding debt with VEBA AG and
its affiliates maturing prior to January 1, 2001 which is extended at maturity
will be repriced based upon then-current interest rates applicable to an average
industrial borrower at a specified credit rating.

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

Subsequent to year-end, the Company received a $75.0 million short-term
revolving credit facility from an affiliate of VEBAAG. The interest rate on the
credit facility reflects interest rate spreads applicable to an average
industrial borrower at a specified credit rating. Under the loan agreement, the
Company cannot pledge any of its assets to secure additional financing.
Management believes this will satisfy the Company's short-term liquidity needs.

During 1998, the Company repurchased 893,000 shares of common stock for a total
of $15.7 million.

On October 22, 1998, the Company filed a registration statement with the
Securities and Exchange Commission (SEC) for the sale of its common stock in a
rights offering to existing stockholders except VEBA AG and its affiliates (the
Offering). The Company expects approximately $91.1 million in aggregate net
proceeds from the Offering, after paying estimated expenses, including fees to
dealer managers. Immediately prior to the Offering, the Company will sell common
stock to VEBA Zweite Verwaltungsgesellschaft mbH, an affiliate of VEBA AG (VEBA
Zweite), for aggregate net proceeds of approximately $105.9 million. VEBA Zweite
has also agreed to purchase all shares issuable upon exercise of the rights that
are not subscribed for pursuant to the basic subscription privilege or the
over-subscription privilege by other stockholders, subject to certain conditions
that are customary in a firm commitment underwriting. The subscription price and
number of shares will be determined based on the average share price during a
period shortly before the effective date of the registration statement. The
Company intends to use the proceeds from the Offering and the private placement
to reduce debt outstanding under revolving credit agreements and for general
corporate purposes. The Company expects the registration to be effective and the
Offering to commence by the end of the first quarter of 1999. The private
placement to VEBA Zweite will be consummated immediately prior to commencement
of the Offering.

Management currently believes that cash generated from operations, together with
the liquidity provided by existing cash balances and credit facilities and the
anticipated proceeds from the private placement and the Offering will be
sufficient to satisfy commitments for capital expenditures and other cash
requirements into 2000. If the Offering is not completed, the Company may need
to explore other future sources of capital.

The silicon wafer industry is highly capital intensive. Even with the proceeds
from the private placement to VEBA Zweite and the Offering (if such transactions
are consummated) and anticipated cash from operations, the Company may need to
seek additional capital in order to fund all its future needs for capital
expenditures, research and development, and marketing and customer service and
support. The Company's capital needs depend on numerous factors, including its
profitability and investment in capital expenditures and research and
development.

Historically, the Company has funded its operations primarily through loans from
VEBA AG and its affiliates, internally generated funds, and an initial public
offering. To a lesser extent, the Company has raised funds by borrowing money
from commercial banks. The Company will continue to explore and, as appropriate,
enter into discussions with other parties regarding possible future sources of
capital. Under the loan agreements between the Company and its principal lender,
VEBA AG and its affiliates, the Company cannot pledge any of its assets to
secure additional financing. The Company does not believe that it currently can
obtain unsecured financing from third parties on better terms than those with
VEBA AG and its affiliates.

For financial reporting purposes, both VEBA Corporation and VEBA AG include VEBA
Corporation's share of the Company's net earnings or losses in their
consolidated financial statements. The Company's recent losses have adversely
affected VEBA Corporation's and VEBA AG's reported earnings. While the Company
is not one of the focus areas of VEBA AG and its affiliates' future major
investments, they have recently provided the Company with additional capital and
have committed to provide substantial additional capital, as described herein.
However, VEBA AG and its affiliates are not otherwise obligated to provide
capital to the Company. There can be no assurance that VEBA AG and its
affiliates will continue to provide capital to the Company in the future.

YEAR 2000

Many existing software programs, computers and other types of equipment were not
designed to accommodate the Year 2000 and beyond. If not corrected, these
computer applications and equipment could fail or create erroneous results. For
the Company, this could disrupt purchasing, manufacturing, sales, finance and
other support areas and affect the Company's ability to timely deliver silicon
wafers with the exacting specifications required by the Company's customers,
thereby causing potential lost sales and additional expenses.


                                       18

STATE OF READINESS. The Company has created a Year 2000 Project Team that is
comprised of a Program Office, including a Global Project Manager, Customer and
Vendor Management groups, and Year 2000 representatives from all sites around
the world, including the Company's unconsolidated joint ventures. This team is
responsible for planning and monitoring all Year 2000 activities and reporting
to the Company's executive management. The Company's Chief Financial Officer is
the sponsor for the Year 2000 project and reports to the Company's Board of
Directors on a periodic basis. 

The Company's Year 2000 project encompasses both information and non-information
systems within the Company as well as the investigation of the readiness of the
Company's strategic suppliers/business partners. The Company's goal is to have
all Year 2000 issues resolved by June 1999, with Year 2000 issues relating to
the most critical business systems (i.e., financial, order processing) resolved
by the first quarter of 1999. To that end, the Company has inventoried and
assessed the Year 2000 readiness of the following:

- - In-house Applications -- Those applications that are developed and supported
  in-house or purchased applications that are heavily customized and supported
  in-house. This classification also includes end-user-developed applications
  deemed critical to the business.

- - Business Software (Purchased) -- Applications purchased from an outside vendor
  and used for automating business processes (i.e., financial systems, order
  processing systems, purchasing systems).

- - Manufacturing Software (Purchased) -- Applications purchased from an outside
  vendor and used for automating manufacturing processes.

- - Personal Computer Software (Purchased) -- All software packages resident on
  personal computers. This includes things such as operating systems, word
  processing software, communications software, project management software, and
  spreadsheet software.

- - Infrastructure Software (Purchased) -- Purchased software used in the
  client/server and network environments.

- - IT Hardware -- Information Technology hardware components including midrange
  machines, personal computers, printers, network hardware.

- - Facilities & Utilities -- Components in the office and manufacturing
  supporting systems environments. Types of components include: copy machines,
  fax machines, telephone/communications systems, security systems, fire
  alarm/control, electrical, waste treatment, alarms, and air handlers.

- - Manufacturing Equipment -- Shop floor equipment such as clean rooms, crystal
  pullers, epitaxial reactors, inspection, lab, lappers, laser markers,
  measurement tools, grinders, polishers, slicers, and wet benches.

IN-HOUSE APPLICATIONS. The Company is evaluating the extent to which
modifications of the Company's in-house applications will be necessary to
accommodate the Year 2000 and are modifying the Company's in-house applications
to enable continued processing of data into and beyond the Year 2000. This phase
of the Company's Year 2000 project is approximately 75% complete and the Company
anticipates completing remediation and testing of the Company's in-house
applications by the end of the first quarter of 1999.

PURCHASED SOFTWARE. The Company is obtaining, where feasible, contractual
warranties from systems vendors that their products are or will be Year 2000
compliant. The Company has completed approximately 85%, 55% and 75% of its Year
2000 project related to business software, manufacturing software and personal
computer software, respectively, and has completed its Year 2000 project related
to infrastructure software. The Company expects this phase of its Year 2000
project to be completed by the end of the first quarter of 1999. The Company
requires Year 2000 contractual warranties from all vendors of new software and
hardware. In addition, the Company is testing newly purchased computer hardware
and software systems in an effort to ensure their Year 2000 compliance.

EMBEDDED SYSTEMS. For in-house embedded systems, the Company is modifying its
systems to enable the continuing functioning of equipment into and beyond the
Year 2000. For third-party embedded systems, the Company is obtaining, where
feasible, contractual warranties from systems vendors that their products are or

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

will be Year 2000 compliant. The Company has completed this phase of its Year
2000 project for hardware and has completed approximately 65% and 55% of its
Year 2000 project related to facilities and utilities, and manufacturing
equipment, respectively. The Company anticipates that such embedded systems will
be fully tested by June 1999.

SUPPLIERS/BUSINESS PARTNERS. The Company has also communicated with its
strategic suppliers and equipment vendors seeking assurances that they will be
Year 2000 ready. The Company's goal is to obtain as much detailed information as
possible about its strategic suppliers/business partners' Year 2000 plans so as
to identify those companies which appear to pose a significant risk of failure
to perform their obligations to the Company as a result of the Year 2000.
Detailed information regarding all of its strategic suppliers and equipment
vendors has been compiled and Year 2000 audits are planned for the most critical
suppliers. This will be an ongoing process during the Company's Year 2000
project. For those strategic suppliers and equipment vendors that do not respond
as to their status or their response is not satisfactory, the Company intends to
develop contingency plans to ensure that sufficient resources are available to
continue with business operations.

COSTS TO ADDRESS THE YEAR 2000. Spending for modifications and updates is being
expensed as incurred and is not expected to have a material impact on the
Company's results of operations or cash flows. The cost of the Company's Year
2000 project is being funded through borrowings. The Company estimates that its
total incremental Year 2000 expenditures will be in the range of $5 - $7
million. Through December 31, 1998, the Company has expended approximately $2.2
million of incremental costs consisting mainly of contract programmers and
consulting costs associated with the evaluation, assessment and remediation of
computer systems and manufacturing equipment. The Company anticipates that
contract programming costs will be its most significant cost as the Year 2000
project proceeds to completion.

RISK ANALYSIS. Like most large business enterprises, the Company is dependent
upon its own internal computer technology and relies upon the timely performance
of its suppliers/business partners. A large-scale Year 2000 failure could impair
the Company's ability to timely deliver silicon wafers with the exacting
specifications required by its customers, thereby causing potential lost sales
and additional expenses. The Company's Year 2000 project seeks to identify and
minimize this risk and includes testing of its in-house applications, purchased
software and embedded systems to ensure that all such systems will function
before and after the Year 2000. The Company is continually refining its
understanding of the risk the Year 2000 poses to its strategic
suppliers/business partners based upon information obtained through its surveys.
This refinement will continue into mid-1999.

CONTINGENCY PLANS. The Company's Year 2000 project includes the development of
contingency plans for business critical systems and manufacturing equipment as
well as for strategic suppliers/business partners to attempt to minimize
disruption to its operations in the event of a Year 2000 failure. The Company
will be formulating plans to address a variety of failure scenarios, including
failures of its in-house applications, as well as failures of strategic
suppliers/business partners. The Company anticipates it will complete Year 2000
contingency planning by March 1999.

YEAR 2000 CAUTIONARY STATEMENT. Year 2000 issues are widespread and complex.
While the Company believes it will address them on a timely basis, the Company
cannot guarantee that it will be successful or that these problems will not
materially adversely affect its business or results of operations. To a large
extent, the Company depends on the efforts of its customers, suppliers and other
organizations with which it conducts transactions to address their Year 2000
issues, over which the Company has no control. 

EURO CONVERSION

On January 1, 1999, eleven of the fifteen member countries of the European union
established fixed conversion rates between their existing sovereign currencies
and the Euro. The participating countries have agreed to adopt the Euro as their
common legal currency as of that date while still utilizing their local currency
until January 1, 2002.

The Company has begun to assess the potential impact that may result from the
Euro conversion. In addition to tax accounting considerations, the Company is
also assessing the potential impact from the Euro conversion in a number of
other areas, including the technical challenges to adapt information technology
and other systems to accommodate Euro-denominated transactions; the competitive
impact of cross-border price transparency, which may make it more difficult for
businesses to charge different prices for the same products on a
country-by-coun-


                                       20
<PAGE>   10

try basis; the impact on currency exchange costs and currency exchange rate
risk; and the impact on existing contracts. While the Company will continue to
assess the impact of the introduction of the Euro, based on currently available
information, management does not believe that the introduction of the Euro will
have a material adverse effect on the Company's financial condition or results
of operation.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 requires the recognition of
all derivatives as assets or liabilities within the balance sheet, and requires
both the derivatives and the underlying exposure to be recorded at fair value.
Any gain or loss resulting from changes in fair value will be recorded as part
of the results of operations, or as a component of comprehensive income or loss,
depending upon the intended use of the derivative. SFAS No. 133 is effective for
all fiscal quarters of fiscal years beginning after June 15, 1999. The Company
does not believe that the implementation of this Statement will have a material
adverse effect on its financial condition or results of operations.

In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use." SOP 98-1 requires that certain costs
related to the development or purchase of internal-use software be capitalized
and amortized over the estimated useful life of the software. This Statement
also requires that costs related to the preliminary project stage and the
post-implementation/operations stage of an internal-use computer software
development project be expensed as incurred. SOP 98-1 is effective for financial
statements issued for fiscal years beginning after December 15, 1998. The
Company does not believe that the implementation of this Statement will have a
material adverse effect on its financial condition or results of operations.

RISK FACTORS

Certain statements made in this report are or may constitute "forward looking
statements". These include statements concerning the manner, timing and
estimated savings and effects of the Company's restructuring activities;
estimated cost reductions for the global purchasing, plant focus and other
initiatives; the Company's expectations for an increase in market demand for
silicon wafers and semiconductors and an easing of pressure on pricing and
margins in the year 2000; the Company's expectations concerning its lack of
profitability in 1999 and its ability to generate positive operating cash flows
in the year 2000; implementation in MEMC plants of QS 9000 and ISO 14001
certification; the transfer of Spartanburg-based small diameter production
activities to other existing locations; utilization of the restructuring
reserve; realization of the net deferred tax asset as it relates to the
Company's ability to generate future taxable income; capital expenditures in
1999; the expectations concerning Taisil and the Taiwanese silicon wafer market;
the consummation of the pending private placement to VEBA Zweite and the
Offering; the continued support of the Company by VEBA AG and its affiliates;
and the status, effectiveness and projected completion of the Company's Year
2000 initiative.

Because these matters are subject to risks and uncertainties, actual results may
differ materially from those expressed or implied by forward looking statements.
Factors that could cause actual results to differ materially include the demand
for semiconductors worldwide; changes in the pricing environment for the
Company's products; changes in financial market conditions; the economic
conditions in the Asia Pacific region and Japan; actions taken by the Company's
competitors; the willingness of the Company's customers to re-qualify
Spartanburg-based production to other locations; the accuracy of assumptions
made by the Company regarding savings from its restructuring activities; changes
in interest and exchange rates; and those risk factors described in "Risk
Factors" and set forth in our Form 10-K for the 1998 fiscal year.

Undue reliance should not be placed on these forward looking statements, which
speak only as of the date that they are made. The Company does not undertake any
obligation to release publicly any revisions to these statements to reflect
later events or circumstances or to reflect the occurrence of unanticipated
events.

MARKET RISK

Market risks relating to the Company's operations result primarily from changes
in interest rates and changes in foreign exchange rates. The Company enters into
currency swaps to minimize the risk and costs associated with its financing
activities in currencies other than its functional currency. The Company does
not hold derivatives for trading purposes.

The following table provides information about the Company's financial
instruments that are sensitive to changes in interest rates. For debt
obligations, the table presents principal maturities and related

and $8,610 of the Japanese Yen denominated debt in 2000 at interest rates
reflecting new maturities to 2001 and interest rate spreads applicable to an
average industrial borrower at a specified credit rating.

The Company routinely enters into forward currency exchange contracts in the
regular course of its business to manage its exposure against foreign
currencies. The Company had $30.8 million in foreign currency contracts
outstanding at December 31, 1998 with an estimated fair value of $32.1 million.
These contracts are for a short duration, generally less than six months, and
their contract values approximate fair value. Thus, they have been omitted from
the table below. In addition, the Company entered into foreign currency swaps to
hedge a portion of its debt in Japan. For debt obligations, the table presents
debt obligations which are held by the Company in a currency that is not its

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Dollars in thousands, except share data

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

1 - NATURE OF OPERATIONS

MEMC Electronic Materials, Inc. and subsidiaries (the Company) is a leading
manufacturer and worldwide supplier of electronic grade silicon wafers for the
semiconductor industry. The Company has production facilities directly or
through joint ventures in Italy, Japan, Malaysia, South Korea, Taiwan and the
United States. The Company's customers are located throughout the world.

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

2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a) Basis of Presentation
The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles (GAAP) 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 consolidated financial statements, and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

Certain prior period amounts have been reclassified to conform to the current
year's presentation. 

(b) Principles of Consolidation
The consolidated financial statements include the accounts of MEMC Electronic
Materials, Inc. and its wholly and majority-owned subsidiaries. Investments of
less than 50% in two joint venture companies are accounted for using the equity
method. All significant intercompany transactions have been eliminated.

(c) Cash Equivalents
Cash equivalents consist of cash in banks, principally overnight investments and
short-term time deposits, with original maturities of three months or less.

(d) Inventories
Inventories are stated at the lower of cost or market. Raw materials and
supplies inventories are valued using the first-in, first-out method. Goods in
process and finished goods inventory values are based upon standard costs which
approximate average costs.

(e) Property, Plant and Equipment
Property, plant and equipment are stated at cost. Depreciation is computed
principally using the straight-line method over estimated service lives as
follows:

The Company capitalizes interest costs as part of the cost of constructing
facilities and equipment. Interest costs of $5,521, $15,968 and $8,957 were
capitalized in 1998, 1997 and 1996, respectively.

(f) Excess of Cost Over Net Assets Acquired
Excess of cost over net assets acquired (goodwill) is amortized on a
straight-line basis over the periods estimated to be benefited, not exceeding 40
years. Excess of cost over net assets acquired is reviewed for impairment
whenever events and changes in business circumstances indicate the carrying
value of the goodwill and related acquired assets that gave rise to the goodwill
may not be recoverable. Impairment losses are recognized if expected future cash
flows of the related assets are less than their carrying values. There is no
indication of impairment of excess of cost over net assets acquired at December
31, 1998 or 1997.

(g) Computer Software Developed or Obtained for Internal Use
Costs related to the development or purchase of internal-use software are
capitalized and amortized over the estimated useful life of the software. Costs
related to the preliminary project stage and the post- implementation/operations
stage of an internal-use computer software development project are expensed as
incurred.

(h) Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed of
Recoverability of assets to be held and used is measured by a comparison of the
carrying amount of an asset to future net cash flows expected to be generated by
the asset. If such assets are considered to be impaired, the impairment to be
recognized is measured by the amount by which the carrying amount of the assets
exceeds the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell. There is no indication of
impairment of property, plant and equipment at December 31, 1998 or 1997.

(i) Impairment of Investments in Joint Ventures
Impairment of investments in joint ventures is measured by comparing the
carrying amount of the asset to future net cash flows expected to be generated
by the asset. In addition, the level of commitment of the joint venture's
shareholders, the silicon wafer markets serviced by the joint ventures, and the
level of customer qualifications at the joint ventures are also considered in
assessing the impairment of the Company's investments in joint ventures. There
is no indication of impairment of these investments at December 31, 1998 or
1997.

(j) Revenue Recognition
Revenues are recognized when products are shipped.

(k) Derivative Financial Instruments
The Company enters into forward exchange contracts to manage foreign currency
exchange risk relating to current trade receivables with its foreign
subsidiaries and current trade receivables with its customers denominated in
foreign currencies (primarily Japanese yen and Deutsche mark). The purpose of
the Company's foreign currency hedging activities is to protect the Company from
the risk that the eventual dollar net cash flows resulting from foreign currency
transactions will be adversely affected by changes in exchange rates. The
Company does not hold or issue financial instruments for trading purposes. 

The Company's forward exchange contracts are accounted for as hedges and,
accordingly, gains and losses on those contracts are deferred and recognized at
the time of settlement of the related receivables. Deferred gains and losses are
included on a net basis in the consolidated balance sheets as either other
assets or other liabilities. Upon termination, gains and losses are included in
the consolidated statements of operations as other income or expense. If a
forward exchange contract is designated as a hedge but is no longer effective,
it is marked to market and included in other income or expense in the
consolidated statements of operations. A payment or receipt arising from the
termination of a forward exchange contract that is effective as a hedge is
included in other income or expense in the consolidated statements of
operations.

(l) Translation of Foreign Currencies
Assets and liabilities of foreign subsidiaries whose functional currency is
other than the U.S. dollar are translated to U.S. dollars using the exchange
rates in effect at the balance sheet date. Results of operations are translated
using average rates during the period. Adjustments resulting from the
translation process are included as a component of accumulated other
comprehensive income (loss).

(m) Income Taxes
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to material differences between the financial
statement carrying amounts of existing assets and liabilities and their
respective tax bases and operating losses and tax credit carryforwards. Deferred
tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are
expected to be recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in earnings in the period
that includes the enactment date. A valuation allowance has been established for
deferred tax assets that the Company believes may not be realized. No provision
is made for U.S. income taxes on unremitted earnings of the Company's
consolidated non-U.S. subsidiaries, as the retention of such earnings is
considered essential for continuing operations, or the additional taxes are
considered to be minimal based upon available foreign tax credits.

(n) Stock-Based Compensation
The Company measures its compensation cost of equity instruments issued under
employee compensation plans under the provisions of Accounting Principles Board
Opinion No. 25 (Opinion 25) and related Interpretations. Compensation expense
related to restricted stock awards is recognized over the applicable vesting
periods, and the unamortized portion of deferred compensation is reflected as a
separate component of stockholders' equity. The Company does not issue equity
instruments to non-employees.

(o) Comprehensive Income (Loss) Reclassification Adjustment
The Company's decision to forego construction of a new 200 millimeter facility
at its joint venture in Malaysia and to withdraw from its small diameter joint
venture in China resulted in a reclassification adjustment to comprehensive
income (loss) in 1998 of approximately $9,500.

(p) Contingencies
Contingent liabilities are disclosed when management believes they are material
to the Company's financial position. There are no such known contingent
liabilities at December 31, 1998 or 1997.

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

3 - FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amount of the Company's cash, accounts receivable, income taxes
receivable, short-term borrowings, accounts payable and accrued liabilities
approximates fair value due to the short maturity of these instruments.
Consequently, such instruments are not included in the table below which
provides information regarding the estimated fair values of other financial
instruments, both on and off balance sheet, as follows:

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


The fair value of each long-term debt facility is based upon the amount of
future cash flows associated with each instrument discounted at the Company's
current borrowing rate for similar debt instruments of comparable terms.

The Company has entered into forward exchange contracts with VEBA AG and its
affiliates to manage foreign currency exchange risk relating to current trade
sales with its foreign subsidiaries and current trade sales with its customers
denominated in foreign currencies (primarily Japanese yen and Deutsche mark),
and a currency swap contract relating to foreign currency denominated
intercompany loans. The Company believes its hedging arrangements with VEBA AG
and its affiliates allow for transactions on a basis that is comparable to terms
available from unrelated third-party financial intermediaries.

The fair values of the forward and the currency swap contracts were a net gain
to the Company of $957 and $5,332, as measured by the amount that would have
been paid to liquidate and repurchase all open contracts as of December 31, 1998
and 1997, respectively. Deferred losses for intercompany loans totaled $2,897
and $3,437 at December 31, 1998 and 1997, respectively.

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

4 - CONCENTRATION OF CREDIT RISK

The Company sells products to customers in the semiconductor industry which are
located in various geographic regions including the United States, Europe, Japan
and Asia Pacific. The primary customers in this industry are well capitalized
and the concentration of credit risk is considered minimal due to the Company's
customer base. Sales to the Company's largest customer were 20.3%, 20.0% and
16.8% of net sales in 1998, 1997 and 1996, respectively. No other customer
constituted 10% or more of net sales in 1998, 1997 or 1996.

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

5 - RESTRUCTURING COSTS

During the second quarter of 1998, the Company decided to close its small
diameter wafer facility in Spartanburg, South Carolina and to withdraw from its
60%-owned joint venture in a small diameter wafer operation in China. These
actions were taken because (1) a number of semiconductor manufacturers have been
running their larger diameter manufacturing lines in preference to their small
diameter lines in order to gain production efficiencies; (2) a number of
semiconductor manufacturers recently have undertaken restructuring initiatives
focused on permanently eliminating small diameter lines; and (3) management
believes that small diameter wafer capacity will exceed demand even after the
semiconductor industry begins to recover. The Company also decided to forego
construction of a new 200 millimeter wafer facility at its 75%-owned joint
venture in Malaysia. This decision was based upon current and anticipated excess
capacity for 200 millimeter wafers and the significant price erosion that the
Company has experienced for these wafers.

The Company recorded a charge to operations of $121,670 (of which $81,325 is
non-cash) related to the above actions.

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

The assets for which an impairment loss has been recorded or which have or will
be written-off are primarily property, plant and equipment that cannot be sold
or used at other Company facilities. Accordingly, these assets have been written
down to net realizable value. The net balance of Spartanburg property, plant and
equipment before and after the write-off was $50,965 and $14,665, respectively.
Additionally, the Company wrote-off architectural design and site preparation
fees and costs incurred to develop a computer integrated manufacturing system
for the Malaysian joint venture that do not have applicability elsewhere within
the Company. Ongoing operating expenses until plant closure associated with the
Spartanburg facility will continue to be recorded as period costs. Costs
relating to the relocation and installation of equipment from the Spartanburg
facility to other sites will be capitalized as incurred.

The Chinese joint venture assets represent the operating assets of the Company's
60%-owned joint venture in China. The Company anticipates ceding its interest in
the operating assets of the joint venture to the partner in the joint venture,
with which the Company has no other interest, and receiving de minimus proceeds
in conjunction with its withdrawal.

The provision for dismantling and related costs primarily relates to the
Spartanburg facility and includes estimates for the dismantling of the facility,
collection and disposal of process chemicals, decontamination of manufacturing
equipment, modification of the wastewater treatment facility, remaining
operating lease payments on equipment that will not be used elsewhere in the
Company and scrapping charges. Environmental remediation costs of $3,500
relating to the closure of the Spartanburg facility were accrued in accordance
with Statement of Financial Accounting Standards No. 5, "Accounting for
Contingencies".




                                       30

Personnel costs of $12,200 represent the expected severance cost of involuntary
terminations for all hourly and salaried employees at the Spartanburg facility
whom the Company does not expect to relocate elsewhere within the organization.
At December 31, 1998, approximately 240 of these employees had not yet been
terminated. An additional $2,300 restructuring charge relates to severance
benefits for certain employees at other MEMC sites.

In addition to the restructuring activities discussed above, the Company
recorded a $24,654 charge for a voluntary severance program for approximately
600 hourly and salaried U.S. employees. All of this amount was paid to
participants as of December 31, 1998.

Of the $37,299 restructuring reserve at December 31, 1998, approximately $7,000
is non-cash. Half of the approximately $30,000 remaining reserve is expected to
be paid out in the first half of 1999. During this time, the Company will
transfer the small diameter production activities of the Spartanburg facility to
other existing Company locations. The remaining half is expected to be expended
by 1999 year-end and relates primarily to dismantling costs associated with the
Spartanburg facility.

In October 1996, the Company entered into a financing arrangement with the City
of O'Fallon, Missouri related to the expansion of the Company's St. Peters
facility. In total, approximately $252 million of industrial revenue bonds were
issued to the Company by the City of O'Fallon, of which at December 31, 1998 and
1997, $215 million and $210 million was outstanding, respectively.


The bonds were exchanged by the City of O'Fallon for the assets related to the
expansion, which were then leased by the Company for a period of 10 years for
machinery and equipment and 15 years for building and building improvements. The
Company has the option to purchase the machinery and equipment at the end of
five years and the building and building improvements at the end of 10 years.
The industrial revenue bonds bear interest at a rate of 6% per annum and mature
concurrent with the annual payments due under the terms of the lease.

The Company has classified the leased assets as property, plant and equipment
and has established a capital lease obligation equal to the outstanding
principal balance of industrial revenue bonds. Lease payments may be made by
tendering an equivalent portion of the industrial revenue bonds. As the capital
lease payments to the City of O'Fallon may be satisfied by tendering industrial
revenue bonds (which is the Company's intention), the capital lease obligation,
industrial revenue bonds and related interest expense and interest income,
respectively, have been offset for presentation purposes in the consolidated
financial statements.

11 - STOCKHOLDERS' EQUITY

Preferred Stock

The Company has 50,000,000 authorized shares of $.01 par value preferred stock.
The Board of Directors is authorized, without further action by the
stockholders, to issue any or all of the preferred stock.

Common Stock

Holders of the $.01 par value common stock are entitled to one vote for each
share held on all matters submitted to a vote of the stockholders. Subject to
the rights of any holders of preferred stock, holders of common stock are
entitled to receive ratably such dividends as may be declared by the Board of
Directors. In the event of liquidation, dissolution or winding up of the
Company, holders of the common stock are entitled to share ratably in the
distribution of all assets remaining after payment of liabilities, subject to
the rights of any holders of preferred stock.

The Company does not anticipate paying dividends in the foreseeable future. The
declaration and payment of future dividends by the Company, if any, will be at
the sole discretion of the Board of Directors.

Stock-Based Compensation

The Company has an Equity Incentive Plan (the Plan) that provides for the award
of incentive and non-qualified stock options, restricted stock and performance
shares. Total shares authorized for grant under the Plan are 3,597,045.
Non-qualified stock options to employees are typically granted on January 1 and
vest at a rate of 25% annually over four years. Non-qualified stock options to
non-employee directors are also typically granted on January 1 but vest at a
rate of 33 1/3% annually over three years. The exercise price of each option
equals the market price of the Company's common stock on the date of the grant,
and each option's maximum term is 10 years. Total restricted shares awarded in
1997 and 1996 were 1,300 and 38,200, respectively, with weighted average fair
values of $22.50 and $33.46, respectively. Total compensation cost recognized
for these awards in 1998, 1997 and 1996 was $170, $596 and $1,001, respectively.

The Company applies Opinion 25 and related Interpretations in accounting for the
Plan. Accordingly, no compensation cost has been recognized for non-qualified
stock options granted under the Plan. Had compensation cost been determined for
the Company's non-qualified stock options based on the fair value at the grant
dates consistent with the alternative method set forth under Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation," the Company would have reported the following amounts indicated

the computation of diluted loss per share during 1998, because they were
antidilutive.

common stock at $8.50 to $10.50 per share. These options will expire in January
2008.

The Company's net deferred tax assets increased $99.1 million to $127.8 million
at December 31, 1998. Management believes it is more likely than not that, with
its projections of future taxable income and after consideration of the
valuation allowance, the Company will generate sufficient taxable income to
realize the benefits of the net deferred tax assets existing at December 31,
1998.

In order to realize the net deferred tax assets existing at December 31, 1998,
the Company will need to generate future taxable income of approximately $353
million. The Company's net operating loss (NOL) carryforwards total $410
million, of which $7 million will expire in 2001; $15 million will expire in
2002; $32 million will expire in 2003; $27 million will expire in 2012; and $329
million will expire in 2018. There can be no assurance, however, that the
Company will generate sufficient taxable income to realize the full benefit of
the existing net deferred tax assets. The Company also has AMT credit
carryforwards of $3,427 and net investment tax credit carryforwards available of
$1,456. Utilization of $7,053 of loss carryforwards and all of the investment
tax credit carryforwards are subject to limitation under Internal Revenue Code
Sections 382 and 383, respectively. Pursuant to these Internal Revenue Code
sections, the amount of combined loss and tax credit carryforwards that may be
utilized is limited to approximately $2,000 per year. Under Internal Revenue
Service regulations, the investment tax credit carryforwards are not permitted
to reduce income tax expense until the year 2000.

14 - PENSION PLANS AND OTHER RETIREMENT BENEFITS

The Company has a noncontributory defined benefit plan covering most U.S.
employees. Benefits for this plan are based on years of service and qualifying
compensation during the final years of employment. The Company complies with
federal funding requirements. The Company also has a nonqualified plan under the
Employee Retirement Income Security Act of 1974, which provides benefits not
otherwise payable under the above plan due to Internal Revenue Code
restrictions. Eligibility for participation in this plan requires coverage under
the above plan and other specific circumstances.

In addition, the Company sponsors a health care plan that provides
postretirement medical benefits to full-time U.S. employees who meet minimum age
and service requirements. The plan is contributory, with retiree contributions
adjusted annually, and contains other cost-sharing features such as deductibles
and coinsurance. The Company's policy is to fund the cost of medical benefits in
amounts determined at the discretion of management.

In 1998, the Company changed the measurement date for the defined benefit plans
from December 31 to September 30 to improve administrative efficiencies and the
timeliness and accuracy of its financial reporting and planning process. The
effect on retirement plan expense was not material to the consolidated financial
statements.

Net periodic pension cost consists of the following:

For measurement purposes, a 6% annual rate of increase in the per capita cost of
covered health care benefits was assumed for 1998. The rate was assumed to
decrease gradually to 5% by the year 2001 and remain at that level thereafter.

Assumed health care cost trend rates have a significant effect on the amounts
reported for health care plans. A one-percentage change in assumed health care
cost trend would have the following effects:

20 - SUBSEQUENT EVENTS-PRIVATE PLACEMENT AND RIGHTS OFFERING

On October 22, 1998, the Company filed a registration statement with the SEC for
the sale of its common stock in a rights offering to existing stockholders
except VEBA AG and its affiliates (the Offering). The Company expects
approximately $91.1 million in aggregate net proceeds from the Offering, after
paying estimated expenses, including fees to dealer managers. Immediately prior
to the Offering, the Company will sell common stock to VEBA Zweite for aggregate
net proceeds of approximately $105.9 million. VEBA Zweite has also agreed to
purchase all shares issuable upon exercise of the rights that are not subscribed
for pursuant to the basic subscription privilege or the over-subscription
privilege by other stockholders, subject to certain conditions that are
customary in a firm commitment underwriting. The subscription price and number
of shares will be determined based on the average share price during a period
shortly before the effective date of the registration statement. The Company
intends to use the proceeds from the Offering and the private placement to
reduce debt outstanding under revolving credit agreements and for general
corporate purposes. The Company expects the registration to be effective and the
Offering to commence by the end of the first quarter of 1999. The private
placement to VEBA Zweite will be consummated immediately prior to commencement
of the Offering.


Subsequent to year-end, the Company received a $75,000 short-term revolving
credit facility from an affiliate of VEBAAG. The interest rate on the credit
facility reflects interest rate spreads applicable to an average industrial
borrower at a specified credit rating. Under the loan agreement, the Company
cannot pledge any of its assets to secure additional financing.

These consolidated financial statements are the responsibility of the Company's

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 MEMC Electronic
