    Our customers demand increasingly complex and technologically advanced
printed circuit boards with high layer counts, dense circuitry designs, high
performance materials and precision cavities. Our engineering and manufacturing
capabilities enable us to produce, in volume, printed circuit boards of 34
layers utilizing high performance materials and leading-edge fabrication
techniques. Our manufacturing facility is designed to meet the accelerated
time-to-market and time-to-volume requirements of customers whose markets are
characterized by high growth rates, rapid technological advances and short
product life-cycles. We believe our on-time delivery record,

                                       4
<PAGE>
which has consistently exceeded 95%, and product return rate, which is less than
0.5%, are among the best in the industry. We believe we are one of a limited
number of interconnect manufacturers with the advanced process technology and
manufacturing and engineering expertise necessary to offer these high-end
products and services.

    The worldwide market for rigid printed circuit boards in 1998 was
$30.2 billion and is projected to grow to $43.0 billion in 2001. High-end
commercial equipment manufacturers require more complex multilayer interconnect
solutions with advanced materials, narrow line widths and separations of copper
traces, precision cavities and small diameter vias and through-holes to connect
internal circuitry. The market for these more complex printed circuit boards was
18.2% of the total market in 1998 and is projected to grow to 24.3% of the total
market in 2001. Sales of high performance printed circuit boards are projected
to grow at a compound annual growth rate of approximately 25.0% over the next
two years.

STRATEGY

    Our objective is to continue to be a preferred supplier of technologically
sophisticated interconnect solutions for leading OEMs and contract manufacturers
in high growth segments of the electronics industry. The key elements of our
strategy include:

    - Continue to focus on both market and technology leaders in selected high
      growth end-markets;

    - Extend our technology leadership;

    - Provide an integrated manufacturing solution;

    - Enhance our reputation as the customer service leader;

    - Invest in capacity and technology; and

    - Pursue strategic acquisitions and alliances.

                              RECENT DEVELOPMENTS

    On March 16, 2000, we announced our results for the quarter ended
February 29, 2000. Net sales for this quarter were $39.7 million, a 30% increase
over the $30.5 million reported for the third quarter of fiscal 1999. Net income
was $1.7 million or $0.24 per diluted share. Net sales to our customers in the
communications segment of the electronics industry accounted for 52% of net
sales for this quarter and contributed to our increased backlog of
$28.6 million as of February 29, 2000, compared to $22.5 million as of
November 30, 1999.

    Please see Note 1 of Notes to Financial Statements for an explanation of the
determination of the number of shares used in computing per share data. The As
Adjusted Balance Sheet Data summarized above reflects the application of the net
proceeds from the sale of the 2,000,000 shares of common stock offered by Merix
at an estimated public offering price of $      per share and after deducting
the estimated underwriting discounts and commissions and our estimated offering
expenses.

(1) EBITDA, which we calculate as income (loss) before taxes, interest income
    and interest expense, plus depreciation and amortization, is a supplemental
    financial measurement used by us in the evaluation of our business and by
    many analysts in our industry.

   However, EBITDA should not be considered as an alternative to net income as a
    measure of operating results or to cash flows as a measure of liquidity in
    accordance with generally accepted accounting principles.

                                  RISK FACTORS

    THIS OFFERING AND AN INVESTMENT IN OUR COMMON STOCK INVOLVE A HIGH DEGREE OF
RISK. YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND THE OTHER
INFORMATION IN THIS PROSPECTUS BEFORE INVESTING IN OUR COMMON STOCK. OUR
BUSINESS AND RESULTS OF OPERATIONS COULD BE SERIOUSLY HARMED BY ANY OF THE
FOLLOWING RISKS. THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE DUE TO ANY
OF THESE RISKS, AND YOU MAY LOSE PART OR ALL OF YOUR INVESTMENT.

BECAUSE A SMALL NUMBER OF CUSTOMERS ACCOUNT FOR A SUBSTANTIAL PORTION OF OUR
REVENUE, OUR REVENUE COULD DECLINE IF WE LOSE A MAJOR CUSTOMER OR IF A MAJOR
CUSTOMER DEMANDS LESS OF OUR PRODUCTS OR CANCELS OR DELAYS ORDERS.

    Historically, we have derived a significant portion of our revenue from a
limited number of customers. For example, our top five customers represented
73.6%, 67.8% and 75.1% of our net sales in the first six months of fiscal 2000
and in fiscal 1999 and 1998, respectively. In fiscal 1999, Cisco Systems,
Motorola, Hewlett-Packard and Tektronix each accounted for more than 10% of our
net sales, and in the six-month period ended November 30, 1999, Cisco Systems,
Motorola, Teradyne and Tektronix each accounted for more than 10% of our net
sales. We expect to continue to depend upon a small number of customers for a
significant portion of our net sales for the foreseeable future. The loss of or
decrease in orders from one or more major customers could reduce our revenues.

    The level and timing of orders placed by our customers vary due to a number
of factors, including customer attempts to manage inventory, changes in customer
manufacturing strategies and variations in demand for customer products. Because
we do not obtain long-term purchase orders or commitments from our customers, we
must anticipate the future volume of orders based on discussions with our
customers. We rely on our estimates of anticipated future volumes when making
commitments regarding the level of business that we will seek and accept, the
mix of products that we intend to manufacture, the timing of production
schedules and the levels and utilization of personnel and other resources. A
customer may cancel, reduce or delay orders that were previously made or
anticipated. A significant portion of our backlog at any time may be subject to
cancellation or postponement without penalty. We may not be able to timely
replace canceled, delayed or reduced orders. Significant or numerous
cancellations, reductions or delays in orders by a customer or group of
customers could lead to under-utilization of our installed capacity and harm our
results of operations.

IF ECONOMIC CONDITIONS DECREASE DEMAND FOR ELECTRONIC PRODUCTS OR ADVERSELY
AFFECT THE MARKET FOR ELECTRONIC PRODUCTS, WE COULD EXPERIENCE REDUCED SALES AND
LOWER GROSS MARGINS.

    Our business depends on the electronics industry, which is subject to
intense competition, rapid technological change, short product life cycles and
pricing and margin pressures. When these factors adversely affect our customers,
we may suffer similar effects. Our customers are primarily manufacturers in the
communications, computing, and test and measurement segments of the electronics
industry. At any time, our customers can discontinue or modify products
containing components manufactured by us. This discontinuance or modification
could adversely affect our results of operations.

    In addition, the electronics industry has historically been cyclical and
subject to significant economic downturns characterized by diminished product
demand, rapid declines in average selling prices and over-capacity. For example,
the economic downturn in Asia in 1998 had a negative effect on the prices of
electronic products as demand for electronic products and components declined
and price competition escalated. The electronics industry is likely to
experience recessionary periods in the future. The economic conditions affecting
the electronics

                                       8
<PAGE>
industry, in general, or any of our major customers, in particular, may
adversely affect our operating results.

WE MAY NOT SUCCESSFULLY MANAGE OUR GROWTH AND CAPACITY EXPANSION OR CONTROL OUR
BUSINESS OPERATIONS AFTER THIS EXPANSION.

    We plan to expand our manufacturing capacity by expanding our facilities and
by adding new equipment. Internal growth will require us to expand our
facilities and to improve our operational and information systems. This
expansion involves significant risks. For example, we may encounter construction
delays, equipment delays, labor shortages or disputes and production start-up
problems that could prevent us from meeting our customers' delivery schedules.
In addition, we expect to incur new fixed operating expenses associated with our
expansion efforts, including increases in depreciation expenses and lease
expenses. If our revenues do not increase sufficiently to offset these expense,
our operating results may be harmed.

OUR BUSINESS REQUIRES SUBSTANTIAL CAPITAL, AND WE MAY NOT BE ABLE TO INCREASE
OUR REVENUES OR MAINTAIN OUR MARKET SHARE IF WE DO NOT INCREASE OUR
MANUFACTURING CAPACITY.

    Manufacturing increasingly sophisticated electronic interconnect products
requires substantial investment in advanced production facilities, engineering
and manufacturing expertise and technology. A significant portion of the costs
associated with these investments are fixed costs. In addition, we believe our
long-term competitive position depends in part on our ability to increase
manufacturing capacity. We are currently utilizing approximately 85-90% of the
installed equipment capacity of our manufacturing facility. We anticipate being
able to increase our production output to 100% of our installed equipment
capacity by employing additional manufacturing personnel. Any production output
beyond this level would require us to invest in plant and equipment. We may
obtain additional capacity through acquisitions or expansion of our current
facilities. Either of these alternatives would require substantial additional
capital, and we may not be able to access sufficient capital to pursue either of
these alternatives. Further, we may not be able to acquire sufficient capacity
or successfully integrate and manage additional facilities, and expanding our
current facilities could take up to two years. Our recent expansion of our
Forest Grove facility has increased and will continue to increase our fixed
costs, and our future profitability will depend on our ability to utilize our
manufacturing capacity in an effective manner. The failure to obtain sufficient
capacity when needed or to successfully integrate and manage additional
manufacturing facilities could adversely impact our relationships with our
customers and materially adversely affect our business and results of
operations.

IF WE LOSE KEY PERSONNEL, WE COULD EXPERIENCE REDUCED SALES, DELAYED PRODUCT
DEVELOPMENT AND DIVERSION OF MANAGEMENT RESOURCES.

    Our success depends largely on the continued contributions of our key
management, engineering, sales and marketing and professional services
personnel, many of whom would be difficult to replace. We do not have employment
or non-compete agreements with our key personnel. If one or more members of our
senior management were to resign, the loss of personnel could result in loss of
sales, delays in new product development and diversion of management resources.
We do not maintain "key man" insurance policies on any of our personnel and do
not require our personnel to enter into non-competition agreements with us.

                                       9
<PAGE>
IF WE ARE NOT ABLE TO RETAIN OR ATTRACT EMPLOYEES WITH SUFFICIENT KNOW-HOW TO
CONDUCT OUR MANUFACTURING PROCESSES, WE MAY NOT BE ABLE TO MAINTAIN OR INCREASE
OUR PRODUCTION OUTPUT AND QUALITY.

    Manufacturing printed circuit boards requires employees with sufficient
know-how to operate advanced equipment and to conduct sensitive and complicated
manufacturing processes. There is intense competition for these types of
employees. We have been successful in attracting and retaining a sufficient
number of these employees in our operations to date. In the future, we may not
be able to attract and retain a sufficient number of these employees for our
existing operations or our planned expanded operations.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY.

    Our quarterly results of operations have varied in the past and may vary
significantly in the future for a variety of reasons, including the following:

    - economic conditions in the markets we serve;

    - price and product competition;

    - the timing and volume of our customers' orders;

    - changes in the mix of products we sell;

    - the levels at which we utilize our manufacturing capacity;

    - our level of experience in manufacturing a particular product;

    - difficulties we may face integrating acquired operations;

    - costs associated with adding new geographical locations or expanding our
      facilities;

    - manufacturing process yields;

    - new material and component availability;

    - shortages of experienced labor;

    - the length of our sales cycles;

    - trends in our industry; and

    - general economic conditions.

    Each of these factors has had in the past, and may have in the future, an
adverse effect on our quarterly operating results. In addition, a significant
portion of our operations expenses are relatively fixed in nature and planned
expenditures are based in part on anticipated orders. Any inability to adjust
spending quickly enough to compensate for any revenue shortfalls may magnify the
adverse impact of such revenue shortfalls on our results of operations. As a
result, our operating results may vary significantly from one quarter to the
next.

OUR STOCK PRICE HAS BEEN AND MAY CONTINUE TO BE VOLATILE, WHICH MAY LEAD TO
LOSSES BY INVESTORS.

    Our common stock has experienced significant price volatility, and this
volatility may continue in the future. The market price for our common stock may
be affected by a number of factors, including quarterly variations in our
results of operations, changes in earnings estimates or recommendations by
securities analysts, developments in our industry, sales of substantial numbers
of shares of our common stock in the public market, general market conditions
and other factors, including factors unrelated to our operating performance.
These factors and fluctuations, as well as

                                       10
<PAGE>
general economic, political and market conditions, such as recessions, may
materially adversely affect the market price of our common stock. See "Price
Range of Common Stock."

OUR ABILITY TO USE OUR FEDERAL NET OPERATING LOSS CARRYFORWARDS COULD BE
LIMITED.

    As of May 31, 1999, we had federal net operating loss carryforwards, subject
to review by the Internal Revenue Service, totaling approximately $34.0 million
for federal income tax purposes, which will expire in 2019. Federal net
operating losses can generally be used to offset our taxable income, which
reduces our income tax liability.

    Section 382 of the Internal Revenue Code provides that when a company
undergoes an "ownership change," the company's use of its net operating losses
is limited in each subsequent year. An "ownership change" occurs when, as of any
testing date, the sum of the increases in ownership of each shareholder that
owns five percent or more of the value of a company's stock as compared to that
shareholder's lowest percentage ownership during the preceding three-year period
exceeds fifty percent. For purposes of this rule, shareholders who own less than
five percent of a company's stock are aggregated and treated as a single
five-percent shareholder.

    We may issue shares of our common stock in acquisitions, and persons who
were five percent shareholders of Merix within the past three years, such as
Tektronix, may sell additional shares in the public market. In addition, the
exercise of outstanding options to purchase shares of our common stock may
require us to issue additional shares of our common stock. These stock issuances
and sales after this offering could result in an "ownership change." If we were
to experience such an "ownership change," our ability to use our net operating
loss carryforwards could be limited.

ACQUISITIONS MAY BE COSTLY AND DIFFICULT TO INTEGRATE, DIVERT MANAGEMENT
RESOURCES OR DILUTE SHAREHOLDER VALUE.

    As part of our business strategy, we may make acquisitions of, or
investments in, companies, products or technologies that complement our current
products, augment our market coverage, enhance our technical capabilities or
production capacity or that may otherwise offer growth opportunities.

    In connection with these acquisitions or investments, we could:

    - issue stock that would dilute our current shareholders' percentage
      ownership;

    - incur debt and assume liabilities; and

    - incur amortization expenses related to goodwill and other intangible
      assets or incur large and immediate write-offs.

    Future acquisitions also could pose numerous additional risks to our
operations, including:

    - problems integrating the purchased operations, technologies or products;

    - unanticipated costs;

    - diversion of management's attention from our core business;

    - adverse effects on existing business relationships with suppliers and
      customers;

    - entering markets in which we have no or limited prior experience; and

    - potential loss of key employees, particularly those of the purchased
      organization.

                                       11
<PAGE>
    We may not be able to complete one or more acquisitions or integrate the
operations, products or personnel gained through any such acquisition without a
material adverse effect on our business, financial condition and results of
operations.

COMPETITION IN THE MARKET FOR ELECTRONIC INTERCONNECT SOLUTIONS IS INTENSE, AND
COULD REDUCE OUR SALES AND PREVENT US FROM ACHIEVING OR MAINTAINING
PROFITABILITY.

    The market for electronic interconnect solutions is intensely competitive,
highly fragmented and rapidly changing. We expect competition to persist and
intensify, which could result in price reductions, reduced gross margins and
loss of market share. We believe our major competitors are the large United
States and international independent captive producers that also manufacture
multilayer printed circuit boards and provide backplane and other electronic
assemblies, such as Hadco, Honeywell, Multek (a division of DII Group), Sanmina,
Tyco International and Viasystems. New and emerging technologies may result in
new competitors entering our market.

    Many of our competitors and potential competitors have a number of
significant advantages over us, including:

        significantly greater financial, technical, marketing and manufacturing
    resources;

        preferred vendor status with our existing and potential customers;

        greater name recognition; and

        larger customer bases.

    In addition, these competitors may have the ability to respond more quickly
to new or emerging technologies, may adapt more quickly to changes in customer
requirements and may devote greater resources to the development, promotion and
sale of their products than us. We must continually develop improved
manufacturing processes to meet our customers' needs for complex products, and
our basic interconnect technology is generally not subject to significant
proprietary protection. We may not be able to maintain or expand our sales if
competition increases and we are unable to respond effectively. During
recessionary periods in the electronics industry, our competitive advantages in
the areas of providing an integrated manufacturing solution and responsive
customer service may be of reduced importance to our customers which may become
more price sensitive.

    We believe price competition from printed circuit board manufacturers in
Asia and other locations with lower production costs may play an increasing role
in the printed circuit board markets in which we compete. While historically our
competitors in these locations have primarily competed in less technologically
advanced markets, they continue to expand their technology to include higher
technology printed circuit boards. These competitors may gain market share in
the market for higher technology printed circuit boards, which may have a
material adverse effect on the pricing of our products and our gross margin and
cause our sales to decrease.

WE COULD FAIL TO DEVELOP OR UTILIZE NEW TECHNOLOGIES OR COMPETE WITH COMPANIES
THAT DEVELOP AND UTILIZE NEW TECHNOLOGIES MORE EFFECTIVELY THAN WE DO.

    The market for electronic interconnect solutions is characterized by rapidly
changing technology and continuing process development. Our future success will
depend in large part upon our ability to timely and cost-effectively:

    - maintain and enhance our technological capabilities;

    - develop and market products and services that meet changing customer
      needs; and

    - successfully anticipate or respond to technological changes.

                                       12
<PAGE>
    In addition, the electronic interconnect industry in the future could
encounter competition from new technologies that render existing electronic
interconnect technology less competitive or obsolete, including technologies
that may reduce the number of printed circuit boards required in electronic
equipment. We may not be able to effectively respond to the technological
requirements of the evolving market. If we determine that new technologies and
equipment are required to remain competitive, we may have to invest significant
capital in the development, acquisition and implementation of these technologies
and equipment. We may not be able to access sufficient capital for this purpose
in the future. In addition, investments in new technologies may not provide us
with commercially viable technological processes, or there may not be commercial
applications for the technologies we acquire or develop. If we are unable to
develop or utilize new technologies or if our competitors are more effective at
developing or utilizing new technologies, our business could be harmed.

WE RELY ON OUR SUPPLIERS FOR COMPONENTS AND RAW MATERIALS, WHICH MAY NOT TIMELY
MEET OUR SUPPLY DEMANDS.

    We order raw materials and components to complete our customers' purchase
orders. Although we work with our customers and suppliers to minimize the impact
of shortages in materials, we have occasionally experienced short-term effects
due to price fluctuations and delayed shipments. If a significant shortage of
raw materials or components were to occur, our operating results would be
materially adversely affected. We also depend on a small number of suppliers for
many of the raw materials and components that we use in our business. If we were
unable to continue to purchase these raw materials and components from our
suppliers, our operating results would be materially adversely affected.

DEFECTS IN OUR PRODUCTS COULD DIMINISH DEMAND FOR OUR PRODUCTS AND RESULT IN
LOSS OF REVENUE, DELAY IN MARKET ACCEPTANCE AND INJURY TO OUR REPUTATION.

    Complex electronic interconnect products like ours may contain undetected
errors or defects that may be detected at any point in the life of the product.
We have in the past discovered errors in our products and as a result have
experienced delays in shipment of products during the period required to correct
these errors. Errors may be found from time to time in our products after
commencement of commercial shipments, resulting in loss of revenue, delay in
market acceptance and sales, diversion of development resources, injury to our
reputation or increased warranty costs.

IF WE BECOME SUBJECT TO PRODUCT LIABILITY LITIGATION, IT COULD BE COSTLY AND
TIME CONSUMING TO DEFEND.

    Since our products are used in products that are integral to our customers'
businesses, errors, defects or other performance problems could result in
financial or other damages to our customers. Although our purchase orders
generally contain provisions designed to limit our exposure to product liability
claims, existing or future laws or unfavorable judicial decisions could negate
such limitation of liability provisions. Product liability litigation, even if
it were unsuccessful, would be time consuming and costly to defend.

WE ARE SUBJECT TO A VARIETY OF ENVIRONMENTAL LAWS.

    We are required to comply with federal, state, county and municipal
regulations regarding protection of the environment. Electronic interconnect
product manufacturing requires the use of a variety of materials, including
metals and chemicals. Water used in the printed circuit board manufacturing
process must be treated to remove metal particles and other contaminants before
it can be discharged into the municipal sanitary sewer system. As a result, we
are subject to various federal, state, local and foreign environmental laws and
regulations, including those governing the

                                       13
<PAGE>
storage use, discharge and disposal of hazardous substances in the ordinary
course of our manufacturing processes. Although we believe our current
manufacturing operations comply in all material respects with applicable
environmental laws and regulations, environmental legislation has been enacted
and may in the future be enacted or interpreted to create environmental
liability with respect to our facilities or operations. We may be responsible
for the cleanup of any contamination discovered at our current and former
manufacturing facilities and could be subject to revocation of permits necessary
to conduct our business. Further, we can not assure you that additional
environmental matters will not arise in the future at sites where no problem is
currently known or at sites that we may acquire in the future.

WE HAVE DISCRETION AS TO THE USE OF THE PROCEEDS FROM THIS OFFERING AND MAY NOT
OBTAIN A SIGNIFICANT RETURN ON THE USE OF THESE PROCEEDS.

    Our management has broad discretion as to how to spend the proceeds from
this offering and may spend these proceeds in ways with which our shareholders
may not agree. We plan to use the proceeds from this offering to purchase new
equipment and expand our production capacity and for working capital and other
general corporate purposes. We may also use some of the proceeds to acquire
other companies, technologies or assets that complement our business. We cannot
predict that investment of the proceeds will yield a favorable return.

OUR CHARTER DOCUMENTS AND OREGON LAW MAY INHIBIT A TAKEOVER OR CHANGE IN OUR
CONTROL THAT A SHAREHOLDER MAY CONSIDER FAVORABLE.

    Provisions in our articles of incorporation, bylaws and shareholder rights
plan may have the effect of delaying or preventing a merger or acquisition of
us, or making a merger or acquisition less desirable to a potential acquirer,
even where the shareholders may consider the acquisition or merger favorable.
Provisions of the Oregon Business Corporation Act and the Control Share Act may
also delay, prevent or discourage someone from acquiring or merging with us.

FUTURE SALES OF OUR STOCK COULD CAUSE THE PRICE OF OUR STOCK TO DECLINE.

    Sales of a substantial number of shares of our common stock in the public
market after this offering could cause the market price of our common stock to
decline. In addition, the sale of these shares could impair our ability to raise
capital through the sale of additional equity securities. Upon completion of
this offering, we will have approximately 8,510,490 shares of common stock
outstanding, approximately 8,810,490 if the underwriters' over-allotment options

<PAGE>
                                USE OF PROCEEDS

    We estimate that the net proceeds to us from the sale of the 2,000,000
shares of common stock that we are offering hereby will be approximately $
million, at an assumed public offering price of $  per share and after deducting
the estimated underwriting discounts and commissions and estimated offering
expenses. We will not receive any proceeds from the sale of shares of common
stock by the selling shareholder.

    We intend to use the net proceeds of this offering to purchase new equipment
and expand our production capacity and for working capital and other general
corporate purposes. We may also use some of the proceeds to acquire other
companies, technologies, or assets that complement our business, although we
have no agreements or understandings relating to any of these transactions.
Pending these uses, we will invest the net proceeds of this offering in
short-term, investment-grade, interest-bearing securities.

    The amounts we actually spend on any particular use of proceeds may vary
significantly depending on a number of factors, including future revenue growth,
the cash we generate or use in our operations and the progress we make in our
sales and marketing efforts.

                                DIVIDEND POLICY

    We currently intend to retain any earnings for use in our business and,
therefore, we do not anticipate paying any cash dividends in the foreseeable
future. We have never declared or paid any cash dividends on our capital stock.
In the future, the decision to pay any cash dividends will depend upon our
results of operations, financial condition and capital expenditure plans, as
well as such other factors as our Board of Directors, in its sole discretion,
may consider relevant.

expenses.

(1) EBITDA, which we calculate as income (loss) before taxes, interest income
    and interest expense, plus depreciation and amortization, is a supplemental
    financial measurement used by us in the evaluation of our business and by
    many analysts in our industry.

   However, EBITDA should not be considered as an alternative to net income as a
    measure of operating results or to cash flows as a measure of liquidity in
    accordance with generally accepted accounting principals.

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

    THE FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
FINANCIAL STATEMENTS AND RELATED NOTES INCLUDED ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    We are a leading manufacturer of technologically advanced electronic
interconnect solutions for use in sophisticated electronic equipment. Our
principal products are complex multilayer printed circuit boards, which are the
platforms used to interconnect microprocessors, integrated circuits and other
components that are essential to the operation of electronic products and
systems.

    We were incorporated in March 1994 to succeed to the business conducted by
the Circuit Board Division of Tektronix. All of the business of the Circuit
Board Division of Tektronix, together with $17.5 million in cash, was
transferred to us immediately prior to the consummation of our initial public
offering in May 1994 in exchange for 6,000,000 shares of our common stock, of
which Tektronix continues to own 1,656,500 shares, and a note in the principal
amount of $10.0 million, of which $2.3 million remained outstanding as of
November 30, 1999.

    We manufacture complex multilayer printed circuit boards primarily for use
in high-end commercial equipment within the communications, computing and test
and measurement segments of the electronics industry. Our strategy since the
beginning of fiscal 1999 has been to increase the percentage of our sales of
printed circuit boards with higher layer counts and more advanced technology,
which generally have higher gross margins.

    For the first six months of fiscal 2000, we supplied our products and
services to 67 customers. Our five largest original equipment manufacturer, or
OEM, customers during this period were Cisco Systems, Hewlett-Packard, Motorola,
Tektronix and Teradyne. Our five largest OEM customers comprised 73.6%, 75.1%
and 67.8% of our net sales during fiscal years 1997, 1998 and 1999,
respectively. For the first six months of fiscal 2000, Cisco Systems, Motorola,
Tektronix and Teradyne each accounted for more than 10% of our net sales.

    We also manufacture and sell our products to contract manufacturers that
assemble components on our products for resale to OEMs. We have included in our
sales to OEMs sales made through contract manufacturers since the beginning of
fiscal 1998. Our largest contract manufacturer customers for the first six
months of fiscal 2000 were Benchmark Electronics, Celestica, SCI Systems and
Solectron.

    In the first quarter of fiscal 1999, we implemented a restructuring plan
designed to improve capacity utilization and lower our cost structure. We closed
our Loveland, Colorado facility, sold our Soladyne facility in San Diego,
California, reduced the headcount in the administrative, engineering and support
groups at our headquarters and reorganized our management team.

    In the third quarter of fiscal 1998, we commenced an expansion plan for our
Forest Grove facility to increase our production capacity and our technological
capabilities. By the end of fiscal 1999, we converted non-manufacturing space to
manufacturing space and added new equipment, at a cost of approximately
$20.0 million. By December 1999, we transferred equipment from our Loveland
facility to Forest Grove. Over the next two fiscal years, we plan to increase
our plant capacity through the addition of new equipment and square footage to
our Forest Grove facility, at a cost of approximately $25.0 million. We expect
to fund this expansion with a combination of the proceeds from this offering,
internally generated funds and lease financing. We expect this expansion to
increase our production capacity by approximately 30%.

                                       20
<PAGE>
    Our products are specially manufactured to our customers' specifications and
are priced to reflect the complexity and sophistication of the product and the
timing of the order. Typically, a customer requests a price quote by sending us
design specifications and volume requirements for a particular product. Orders
may be cancelled or postponed at any time, but we may charge the customer a fee
that varies depending on the timing of the cancellation or postponement.
Periodically, our customers provide us with order forecasts that we use to
manage our capacity commitments. Revenue from product sales is recognized at the
time of shipment.

    Cost of sales consists of materials, labor and overhead. Our gross profit is
affected by various factors, including capacity utilization, product mix,
production yields, price ranges and changes in our manufacturing costs. We are
not a party to any long-term supply contracts and believe there are a number of
potential suppliers for all materials so that the loss of any one supplier would
not materially affect our operations.

    Our fiscal year consists of either the 52 or 53-week period ending on the
last Saturday in May. Fiscal years 1999 and 1998 were both 52-week years and
fiscal year 1997 was a 53-week year. For convenience, all of our fiscal years
are presented as ended on May 31, and all interim periods are presented as ended
on the last day of the last calendar month of the period.

SIX MONTHS ENDED NOVEMBER 30, 1999 AND NOVEMBER 30, 1998 (UNAUDITED)

NET SALES

    Our net sales for the first six months of fiscal 2000 were $70.0 million, an
increase of 38.4% from net sales of $50.5 million in the first six months of
fiscal 1999, primarily as a result of higher levels of demand from existing
customers as the electronic equipment industry recovered from the downturn of
1998. Net sales in the first six months of fiscal 1999 included five months of
sales from our Loveland manufacturing facility ($11.9 million), which we closed
in October 1998, and six

                                       21
<PAGE>
months of sales from our Soladyne manufacturing facility ($3.8 million), which
we sold in February 1999. Sales in the communications market segment increased
both absolutely and as a percentage of sales in the first six months of fiscal
2000 compared to the same period in fiscal 1999 as a result of rapidly
increasing demand for data communications, primarily associated with the growth
of the Internet, and increasing use of wireless communications.

    Our five largest OEM customers represented 73.6% of net sales in the first
six months of fiscal 2000 and 69.3% of net sales in the first six months of
fiscal 1999. Our sales to OEMs include sales made through contract
manufacturers. Our sales to contract manufacturers were 50.1% of net sales in
the first six months of fiscal 2000 and 24.7% of net sales in the first six
months of fiscal 1999. Four customers each accounted for more than 10% of our
net sales in the first six months of fiscal 2000, and two customers each
accounted for more than 10% of our net sales in the first six months of fiscal
1999.

    Our 90-day backlog was $22.5 million at November 30, 1999, compared to
$18.0 million at the end of fiscal 1999. The level and timing of orders placed
by our customers vary due to many factors, including customer attempts to manage
inventory, changes in customers' manufacturing strategies and variation in
demand for customer products. Accordingly, our backlog is not necessarily
indicative of future quarterly or annual financial results.

    Pricing of our products, which had been adversely affected by the
electronics industry slowdown beginning late in fiscal 1998, began to stabilize
during the last half of fiscal 1999 and has remained relatively stable during
the first six months of fiscal 2000. In recent months we have seen increased
customer demand and an increased customer focus on the availability of capacity
rather than product price. Continued price stability of our products is
dependent on a variety of factors including continued strength of customer
orders, capacity utilization in the printed circuit board industry, competition
from domestic printed circuit board companies and potential future competition
from Asian printed circuit board companies.

GROSS PROFIT

    Gross profit (loss) as a percentage of net sales, or gross margin, was 17.5%
in the first six months of fiscal 2000 and (13.2)% in the first six months of
fiscal 1999. Gross margin in the first six months of fiscal 1999 was negatively
affected by a $2.1 million write-off of inventory related to the restructuring
discussed below. In addition, because of the downturn in the electronic
equipment industry in 1998, our capacity utilization in the first six months of
fiscal 1999 was significantly below our historical capacity utilization levels.
Gross profit increased in the first six months of fiscal 2000 primarily as a
result of higher capacity utilization, a favorable product mix and cost
reductions. Our product mix was favorable because we produced a greater number
of advanced technology printed circuit boards and quick-turn printed circuit
boards, which provide significantly higher gross margins. Our cost reductions
consisted of higher production yields, manufacturing process improvements and
lower raw material costs because of better supplier arrangements.

OPERATING EXPENSES

    ENGINEERING.  Engineering expenses primarily consist of salaries and related
expenses for engineering personnel who evaluate and assess our production
capabilities for new projects and manage and enhance our techniques and controls
throughout the manufacturing process. Engineering expenses also include costs
related to research and development. Our engineering expenses were $2.1 million
and $2.0 million in the first six months of 2000 and 1999, respectively,
representing 3.0% and 4.1% of our net sales in those periods. Engineering
expenses were reduced in the first six months of fiscal 1999 as a result of the
capitalization of $650,000 in engineering labor expenses related to the Forest
Grove expansion project. These costs are being amortized over

                                       22
<PAGE>
approximately seven years, commencing in fiscal 1999. We also reduced
engineering headcount as a result of the restructuring discussed below.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses primarily consist of salaries and related expenses for management,
sales and marketing, finance and accounting personnel. Our selling, general and
administrative expenses were $4.9 million and $4.9 million in the first six
months of fiscal 2000 and fiscal 1999, respectively, representing 7.0% and 9.7%
of our net sales in those periods. An increase in selling expenses in fiscal
2000, resulting from a larger sales force and higher commissions on greater net
sales, was offset by a decrease in general and administrative costs primarily
due to reduced headcount resulting from the restructuring.

    RESTRUCTURING.  In the first quarter of fiscal 1999, we implemented a
restructuring plan designed to improve capacity utilization and lower our cost
structure. We closed our Loveland, Colorado facility in October 1998 and laid
off approximately 340 manufacturing and support employees located there, sold
our Soladyne facility in San Diego, California and laid off approximately 35
employees from administrative, engineering and support functions at our Forest
Grove, Oregon location. We also transferred a portion of the manufacturing
equipment used in the Loveland facility to our Forest Grove site. Installation
of the manufacturing equipment was completed in December 1999.

    In the third quarter of fiscal 1999, we reversed $7.1 million of the
restructuring expense taken in the first quarter of fiscal 1999, primarily
because lease termination costs at Loveland were $3.1 million less than we had
anticipated, we were able to realize a higher value on inventory than we had
previously written down and we realized $2.8 million more from the sale of
equipment than we had expected. We also spent less on severance benefits than we
expected.

    The components of the restructuring expense, and the subsequent reversal,
were as follows:

    Cash proceeds from asset sales of $4.8 million are reflected in the amounts
shown above for write-down and write-off of manufacturing equipment and
inventory. All cash payments for severance benefits, lease termination costs and
other costs related to the restructuring expense were paid in fiscal 1999. As of
May 31, 1999, there were no outstanding liabilities associated with the
restructuring plan.

                                       23
<PAGE>
INTEREST INCOME

    Our interest income decreased to $341,000 in the first six months of fiscal
2000 from $477,000 in the first six months of fiscal 1999, primarily because we
had lower levels of cash.

INTEREST EXPENSE

    Interest expense increased to $1.6 million in the first six months of fiscal
2000 from $1.2 million in the first six months of fiscal 1999, primarily because
we capitalized interest of approximately $400,000 related to the Forest Grove
expansion project in the first six months of fiscal 1999, which is being
amortized over approximately seven years, commencing in fiscal 1999.

OTHER INCOME (EXPENSE), NET

    Other income (expense), net, was ($317,000) in the first six months of
fiscal 2000, as compared to ($198,000) in the first six months of fiscal 1999.
In the first six months of fiscal 2000, we incurred finance charges of $75,000
in connection with the restructuring of our senior unsecured notes and retired
manufacturing equipment.

INCOME TAXES

    Our effective tax rate was approximately 39% in the first six months of
fiscal 2000 compared to 38% in the first six months of fiscal 1999. We expect
our effective tax rate for fiscal 2000 to approximate 39%. The net operating
losses we incurred in fiscal 1999 are available for carryforward. We expect
these net operating loss carryforwards to offset our taxable income for fiscal
2000.

FISCAL YEARS 1999 AND 1998

NET SALES

    Our net sales were $114.0 million in fiscal 1999, a decrease of 36.2% from
net sales of $178.6 million in fiscal 1998. The decrease in net sales in fiscal
1999 was primarily a result of lower unit sales and lower average selling
prices, which resulted from a general electronic equipment industry downturn,
pricing pressures in the printed circuit board industry, excess customer
inventories, the closure of our Loveland manufacturing facility in October 1998
and the sale of our Soladyne manufacturing facility in February 1999.

    Our five largest OEM customers comprised 67.8% of our net sales in fiscal
1999, compared to 75.1% in fiscal 1998. Our sales to OEMs include sales made
through contract manufacturers. Approximately 31.2% of our net sales were
through contract manufacturers in fiscal 1999 compared to 23.7% in fiscal 1998.
Four customers each accounted for more than 10% of our net sales in fiscal 1999,
and three customers each accounted for more than 10% of our net sales in fiscal
1998.

GROSS PROFIT

    Our gross margin was 3.0% in fiscal 1999 and 15.4% in fiscal 1998. The
decrease in gross margin resulted from lower capacity utilization, lower product
pricing, and the effect of the $1.1 million net write-down of inventory related
to our restructuring expense. Our gross margin began to improve in the last half
of fiscal 1999, primarily as a result of increased sales of higher margin
products, increased capacity utilization of our Forest Grove manufacturing
facility, lower costs as a result of headcount reductions from our restructuring
in fiscal 1999, and other cost reduction actions, such as higher production
yields, manufacturing process improvements and lower raw materials costs.

                                       24
<PAGE>
OPERATING EXPENSES

    ENGINEERING.  Our engineering expenses were $4.1 million in fiscal 1999 and
$5.9 million in 1998, respectively, representing 3.6% and 3.3% of our net sales
in those periods. The decrease in engineering expenses resulted from reduced
headcount, cost controls and the capitalization of approximately $650,000 of
dedicated engineering labor related to our Forest Grove expansion project during
fiscal 1999, which is being amortized over approximately seven years, commencing
in fiscal 1999.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses were $9.1 million and $14.3 million in fiscal 1999 and fiscal 1998,
respectively, representing 7.9% and 8.0% of our net sales in those periods. The
absolute decrease in selling, general and administrative expenses was as a
result of reduced headcount resulting from our restructurings in fiscal 1998 and
fiscal 1999, cost controls and reduced selling expenses as a result of lower net
sales.

    RESTRUCTURING.  As discussed above, we incurred a net restructuring expense
of $22.9 million in fiscal 1999. In the second quarter of fiscal 1998, we
recorded a $1.9 million charge for the costs associated with a restructuring
plan undertaken to improve our profitability, which included a work force
reduction, the write-off of manufacturing equipment and other miscellaneous
costs. All liabilities associated with the restructuring plan were paid in the
third quarter of fiscal 1998.

INTEREST INCOME

    Interest income declined to $912,000 in fiscal 1999 from $1.4 million in
fiscal 1998 primarily because we had lower levels of cash, cash equivalents and
short-term investments during fiscal 1999.

INTEREST EXPENSE

    Interest expense declined to $2.9 million in fiscal 1999 from $3.3 million
in fiscal 1998 primarily because we capitalized interest of approximately
$450,000 related to the Forest Grove expansion project in fiscal 1999, which is
being amortized over approximately seven years, commencing in fiscal 1999.

OTHER INCOME (EXPENSE), NET

    Other income (expense), net, was $85,000 in fiscal 1999, as compared to
($290,000) in fiscal 1998. In fiscal 1999, we received a settlement payment and
ceased amortizing goodwill for our Loveland, Colorado facility, which was
written off in connection with the restructuring in fiscal 1999. This positively
affected our other income (expense), net in fiscal 1999.

INCOME TAXES

    Our effective tax rate was approximately 38% in fiscal 1999 compared to 36%
in 1998. Our effective rate for fiscal 1999 was higher than our effective tax
rate in fiscal 1998 because in fiscal 1998 we received a rebate of excess Oregon
state income taxes collected in prior years.

FISCAL YEARS 1998 AND 1997

NET SALES

    Net sales for fiscal 1998 were $178.6 million, an increase of 14.4% from net
sales of $156.2 million in fiscal 1997. The increase in net sales in fiscal 1998
was primarily a result of higher demand for our products and an improvement in
our product mix, including increased sales of higher layer count, higher priced
products.

                                       25
<PAGE>
    Our five largest OEM customers comprised 75.1% of our net sales in fiscal
1998, compared to 73.6% in fiscal 1997. Our sales to OEMs include sales made
through contract manufacturers for fiscal 1998. Approximately 23.7% of our net
sales were through contract manufacturers in fiscal 1998 compared to 14.8% in
fiscal 1997. Three customers each accounted for more than 10% of our net sales
in fiscal 1998 and in fiscal 1997.

GROSS PROFIT

    Our gross margin was 15.4% in fiscal 1998, compared with 14.0% in fiscal
1997. The improvement in gross margin was attributable to higher sales, improved
pricing of our products, improved product mix, reduced raw material costs and
cost reductions resulting from the restructuring which occurred in the second
quarter of fiscal 1998.

OPERATING EXPENSES

    ENGINEERING.  Our engineering expenses were $5.9 million and $6.0 million in
fiscal 1998 and 1997, respectively, representing 3.3% and 3.9% of our net sales
in those periods.

    SELLING, GENERAL AND ADMINISTRATIVE.  Our selling, general and
administrative expenses were $14.3 million and $13.8 million in the fiscal 1998
and 1997, respectively, representing 8.0% and 8.9% of our net sales in those
periods. The absolute increase in selling, general and administrative expenses
was principally a result of an increase in our sales and marketing personnel,
and costs associated with the reorganization and relocation of our sales force.

    RESTRUCTURING.  In fiscal 1998 we recorded a $1.9 million charge for costs
associated with a plan to improve our profitability, consisting of a work force
reduction in our support and administrative functions, the write-down of
manufacturing equipment, and other miscellaneous costs. We paid all liabilities
associated with the restructuring plan in the third quarter of fiscal 1998.

INTEREST INCOME

    Interest income was effectively flat at $1.4 million in fiscal 1998 compared
to $1.4 million in fiscal 1997.

INTEREST EXPENSE

    Interest expense was $3.3 million in both fiscal 1998 and fiscal 1997.
Interest expense for these periods consisted primarily of interest on the
$40.0 million of senior notes we issued in September 1996.

OTHER INCOME (EXPENSE), NET

    Other income (expense), net, was ($290,000) in fiscal 1998, as compared to
$137,000 in fiscal 1997. Other income (expense), net in fiscal 1997 was
positively affected by gain on an equipment transaction.

INCOME TAXES

    Our effective tax rate was approximately 36% in fiscal 1998 compared to 10%
in 1997. In fiscal 1997, we had lower pretax income, which was offset by the
impact of tax exempt municipal interest income. Also, tax exempt interest income
as a percentage of our pretax income was higher in 1997 than in 1998.

    In the fall of 1998, the electronic equipment industry began to recover from
the downturn that started in the spring of 1998. Net sales at our Forest Grove
manufacturing facility increased throughout the last three quarters of fiscal
1999 because of a return of demand from our existing customers, our success in
winning orders for new programs at existing customers and increasing sales in
the computing and communications market segments.

LIQUIDITY AND CAPITAL RESOURCES

    As of November 30, 1999, we had $15.9 million in cash and cash equivalents
and $29.2 million of long-term debt.

    Cash provided by operating activities in the first six months of fiscal 2000
was $6.5 million. Cash provided by operating activities consisted primarily of
net income for the period and adjustments for depreciation and amortization,
offset primarily by an increase in inventories. Our inventories increased as a
result of a higher level of production in the first six months of fiscal 2000.

    Cash provided by investing activities in the first six months of fiscal 2000
was $7.4 million. Cash provided by investing activities included maturities of
short-term investments, net proceeds from the sale-leaseback of equipment offset
by capital expenditures for manufacturing equipment.

    Cash used in financing activities in the first six months of fiscal 2000 was
$3.9 million, which primarily consisted of a principal payment on our senior
unsecured notes.

                                       27
<PAGE>
    Cash provided by operating activities in fiscal 1999 was $4.1 million. Cash
provided by operating activities reflected an increase in deferred income taxes
offset by our net loss for the period. Cash provided by operating activities
also reflects the net restructuring expense and decreases in accounts receivable
and inventories. The increase in deferred income taxes is due mainly to the net
loss in the period. The decreases in accounts receivable and inventories were
primarily due to the lower level of net sales in fiscal 1999.

    Cash used in investing activities in fiscal 1999 was $11.4 million. Cash
used in investing activities consisted of our capital expenditures for
manufacturing equipment of $15.9 million partially offset by $4.5 million of
proceeds from the sale of assets.

    Cash used in financing activities in fiscal 1999 was $2.2 million, which
primarily consisted of our payments of long-term debt.

    In August 1999, we entered into a lease agreement, which allowed us to sell
and leaseback up to $5.0 million of manufacturing equipment. As of November 30,
1999, we had sold $5.0 million of equipment under this agreement. Gains
resulting from these sales are deferred and amortized on a straight-line basis
over the life of the lease. The lease is classified as an operating lease in
accordance with SFAS No. 13, "Accounting for Leases."

    We have a secured note payable to Tektronix with $2.3 million outstanding at
November 30, 1999, which bears interest at 7.5% per year. Principal on this note
of $1.1 million and $1.2 million is payable in June 2000 and June 2001,
respectively.

    We have $36.0 million principal amount of 7.9% senior unsecured notes held
by two insurance companies, with interest payable semi-annually. Semi-annual
principal payments of $4.0 million began in September 1999, with a final
principal payment of $8.0 million due in September 2003. The notes contain
certain financial covenants, including minimum net worth, debt ratio and
interest coverage as well as a make-whole provision covering potential
prepayment penalties. As of November 30, 1999, we were in compliance with all
covenants.

    In March 2000, we obtained an $8.0 million unsecured line of credit from U.
S. Bank National Association, an affiliate of U.S. Bancorp Piper Jaffray. We
have not made any borrowings under this line of credit as of the date of this
prospectus.

    We had capital commitments of approximately $1.7 million as of November 30,
1999, primarily for manufacturing equipment. In addition, over the next two
fiscal years, we will increase our plant capacity through the addition of new
equipment and square footage to our Forest Grove facility, at a cost of
approximately $25.0 million. We expect to fund this expansion with a combination
of the proceeds from this offering, internally generated funds and lease
financing.

    The Internal Revenue Service has examined our federal income tax returns for
fiscal years 1995, 1996 and 1997. Their proposed adjustments are principally
related to the timing of deductions. We are currently appealing some of their
proposed adjustments. We expect the resolution of these issues to result in the
payment of previously deferred federal and state income taxes and interest on
these taxes becoming currently payable. These tax and interest payments could
range from $1.5 million to $2.5 million. These payments will not impact income
tax expense.

    Section 382 of the Internal Revenue Code provides that when a company
undergoes an "ownership change," the company's use of its net operating losses
is limited in each subsequent year. An "ownership change" occurs when, as of any
testing date, the sum of the increases in ownership of each shareholder that
owns five percent or more of the value of a company's stock as compared to that
shareholder's lowest percentage ownership during the preceding three-year period
exceeds fifty percent. As of May 31, 1999, we had federal net operating loss
carryforwards,

                                       28
<PAGE>
subject to review by the Internal Revenue Service, totaling approximately
$34.0 million for federal income tax purposes, which will expire in 2019. We
estimate that the Section 382 limitation, even if triggered, will not have a
significant effect on our ability to use our available federal net operating
loss carryforwards to reduce our taxable income.

    We believe the proceeds of this offering, together with our existing capital
resources and cash generated from operations should be sufficient to meet our
working capital and capital expenditure requirements through at least the next
12 months.

rapid technological advances and short product life-cycles. We believe we are
one of a limited number of interconnect manufacturers with the advanced process
technology and manufacturing and engineering expertise necessary to offer these
high-end products and services.

INDUSTRY OVERVIEW

    Printed circuit boards consist of patterns of electrical circuitry etched
from copper that has been laminated on a board of insulating material. They are
the platforms used to interconnect microprocessors, integrated circuits and
other components that are essential to the operation of electronic products and
systems. Printed circuit boards are customized for specific electronic
applications and are sold to OEMs and contract manufacturers in volumes that
range from several units for prototypes to small quantities for pre-production
to large quantities for volume production. Quick-turn prototypes are used in the
design, test and launch phases of new electronic products and require rapid
manufacturing, with delivery times ranging from as little as 24 hours and as
long as 10 days. Larger volumes of printed circuit boards are needed as a
product progresses past the testing and design phases and into pre-production
and volume production. The worldwide market for rigid printed circuit boards in
1998 was $30.2 billion and is projected to grow to $43.0 billion in 2001.

    Printed circuit boards are used in virtually all electronic equipment from
consumer products, such as personal computers, cellular telephones, and
televisions, to high-end commercial electronic equipment, such as data
communication routers and switches, wireless base stations, computer
workstations and network servers. Typically, printed circuit boards used in
consumer electronic products are less technologically sophisticated, employing
lower layer counts and lower performance materials and requiring less
manufacturing sophistication than printed circuit boards used in high-end
commercial equipment.

    High-end commercial equipment manufacturers require more complex multilayer
interconnect solutions with advanced materials, narrow line widths and
separations of copper traces, precision cavities and small diameter vias and
through-holes to connect internal circuitry. The market for these more complex
printed circuit boards was 18.2% of the total market in 1998 and is projected to
grow to 24.3% of the total market in 2001. Sales of high performance printed
circuit boards are projected to grow at a compound annual growth rate of
approximately 25% over the next two years.

    We manufacture complex multilayer printed circuit boards primarily for use
in high-end commercial equipment within the communications, computing and test
and measurement segments of the electronics industry. These industry segments
are characterized by high growth, rapid technological change and short product
life-cycles as OEMs continually develop new and technologically superior
products. We believe OEMs and contract manufacturers within these industry
segments will increasingly rely upon manufacturers with the engineering
expertise and process controls to quickly proceed to volume production of
advanced interconnect solutions.

    Manufacturing increasingly sophisticated electronic interconnect products
requires substantial investment in advanced production facilities, engineering
and manufacturing expertise and process technology. These capital and technology
requirements have led to consolidation in recent years, reducing the number of
printed circuit board manufacturers in the United States from approximately 950
in 1992 to approximately 690 in 1998. Despite this consolidation, the printed
circuit board market remains fragmented, and we expect consolidation to
continue. Of the approximately 690 printed circuit board manufacturers in the
United States in 1998, only ten independent manufacturers had revenues in excess
of $100 million, and these manufacturers comprised 44% of the domestic printed
circuit board market.

                                       31
<PAGE>
    There are several significant trends within the electronic interconnect
industry. These include:

    INCREASING COMPLEXITY OF ELECTRONIC EQUIPMENT.  The increasing complexity of
electronic equipment drives technological advancements in interconnect products.
OEMs are continually designing more complex and high performance electronic
equipment, which requires printed circuit boards that accommodate higher speeds,
component densities, frequencies and operating temperatures. We believe this
trend is increasing the demand for interconnect manufacturers with superior
manufacturing process techniques and engineering support.

    EXPANDING AND EMERGING MARKETS.  The demand for more complex multilayer
printed circuit boards is being driven by the expansion of traditional markets
for high-end commercial electronic equipment, such as computing, communications
and test and measurement. In addition, we have seen the emergence of several new
high growth electronic markets, such as wireless communications and Internet
infrastructure. These emerging markets are growing rapidly as a result of
technological changes, demands for wider variety of electronic product features,
greater bandwidth and increasingly powerful electronic components.

    SHORTER PRODUCT LIFE-CYCLES FOR ELECTRONIC PRODUCTS.  Rapid advances in
technology have significantly shortened the life-cycles of complex electronic
products and placed increased pressure on OEMs to develop new products in
shorter periods of time. The time-to-market demands of OEMs have increased
emphasis on the engineering and quick-turn production of small unit volumes of
printed circuit boards in the prototype development stage. In addition, the
success of first-to-market products has heightened the demand for manufacturing
expertise and process controls that enable manufacturers to quickly proceed to
volume production.

    INCREASED DEMAND FOR INTEGRATED PRODUCTS AND SERVICES.  The accelerated
time-to-market and time-to-volume needs of OEMs of high-end equipment have
resulted in increased collaboration with interconnect providers that can offer
design and engineering support and manufacturing scalability throughout the
product life-cycle. Many OEMs are limiting their vendor base to a smaller number
of technically qualified providers that are able to offer a broad range of
interconnect products and services.

STRATEGY

    Our objective is to continue to be a preferred supplier of technologically
sophisticated interconnect solutions for leading OEMs and contract manufacturers
in high growth segments of the electronics industry. The key elements of our
strategy include:

    - CONTINUE TO FOCUS ON BOTH MARKET AND TECHNOLOGY LEADERS IN SELECTED HIGH
      GROWTH END MARKETS. Our OEM customer list includes market leading
      providers of communications equipment such as Cisco Systems and Motorola;
      computer workstations and servers, such as Hewlett-Packard and Intel; and
      test and measurement equipment, such as Teradyne and Tektronix. We are
      also focused on identifying and engaging emerging technology leaders, such
      as Credence Systems, Sonus Networks, Spring Tide Networks, Sycamore
      Networks and Telaxis Communications. Our contract manufacturer customer
      list includes Celestica, Flextronics, Jabil Circuit, SCI Systems and
      Solectron. We will continue to focus our marketing on both market and
      technology leading manufacturers of sophisticated electronic equipment in
      high growth segments of the electronic equipment industry.

    - EXTEND TECHNOLOGY LEADERSHIP. We believe we are a leader in the
      manufacture of advanced interconnect solutions employing high layer
      counts, advanced materials, precision cavities, embedded passives, narrow
      line widths and separations of copper traces and small diameter vias,
      including microvias, and through-holes to connect internal circuitry. Our
      average layer count, which is a widely used indication of manufacturing
      sophistication, has increased from

                                       32
<PAGE>
      7.7 in the first quarter of fiscal 1998 to 10.2 in the second quarter of
      fiscal 2000. In addition, many of our printed circuit boards employ high
      performance materials, such as Teflon-Registered Trademark- and
      Getek-Registered Trademark-. We intend to continue to focus on producing
      next generation interconnect solutions that enable OEMs to
      cost-effectively meet demand for increasingly sophisticated electronic
      products.

    - PROVIDE INTEGRATED MANUFACTURING SOLUTION. We believe our ability to offer
      our customers quick-turn prototypes and pre-production and volume
      production of printed circuit boards through one manufacturing facility
      provides us with a competitive advantage. By using the same processing
      lines to manufacture prototype orders, our prototypes more accurately
      represent our volume products. This allows us to shorten the time in
      transition from the development of prototype designs to volume
      manufacturing and facilitates the volume delivery of high quality complex
      printed circuit boards in a timely fashion.

    - ENHANCE REPUTATION AS THE CUSTOMER SERVICE LEADER. We are committed to
      understanding our customers' needs and exceeding their expectations. We
      believe our on-time delivery record, which has consistently exceeded 95%,
      and product return rate, which is less than 0.5%, are among the best in
      the industry. We have established programs that allow faster, simpler and
      more accurate communications with our customers. These programs include:
      Automated Tooling Interface, which allows our customers to download their
      design data directly to our computer systems for improved speed and
      accuracy; and Electronic Business Transactions with Electronic Data
      Interchange, which streamlines forecasting and order placement processes.

    - INVEST IN CAPACITY AND TECHNOLOGY. We continually invest in our
      manufacturing operations to increase our production capacity and maintain
      the technological expertise our customers demand. We recently increased
      our production capacity at our Forest Grove facility by adding
      manufacturing space and new equipment, which also enhanced our
      technological capabilities. We intend to continue to expand our production
      capacity and further enhance our technological expertise.

    - PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES. The printed circuit board
      market remains fragmented, and we expect consolidation to continue. We
      will pursue strategic acquisitions and alliances with companies whose
      products or technologies complement our current products, augment our
      market coverage or enhance our technical capabilities or production
      capacity.

THE MERIX ADVANTAGE

    We believe Merix has the competitive strengths to continue to be a preferred
supplier to leading OEMs and contract manufacturers in high-growth segments of
the electronics industry. We supply our printed circuit boards primarily to
OEMs within the communications, computing and test and measurement segments of
the electronics industry, such as Cisco Systems, EMC(2), Intel, Motorola and
Teradyne. We are focused on producing next generation interconnect solutions and
have the manufacturing and technological capabilities to fabricate advanced
printed circuit boards in volume and deliver on time. We believe our on-time
delivery record, which has consistently exceeded 95%, and product return rate,
which is less than 0.5%, are among the best in the industry. In addition, we are
able to offer our customers quick-turn prototypes and pre-production and volume
production of printed circuit boards through one manufacturing facility, which
allows us to shorten the time in transition from the development of prototype
designs to volume manufacturing.

PRODUCTS AND SERVICES

    We offer a broad range of products and services designed to meet our
customers' needs for complex multilayer printed circuit boards, backplanes and
backplane assemblies. Our products and services span the period from product
conception through volume production and include the following:

    DESIGN ASSISTANCE AND ENGINEERING SERVICES.  We provide design assistance
and engineering services in the early stages of product development to ensure
that mechanical and electrical elements are integrated to achieve a high quality
and cost-effective product. We also evaluate customer designs for
manufacturability and, when appropriate, recommend design changes to reduce
manufacturing costs and lead times or increase manufacturing yields and the
quality of finished printed circuit boards. We believe this cooperative process
shortens the time in transition from the development of the prototype design to
volume manufacturing and facilitates the delivery of high quality products in a
timely fashion. By working closely with our customers throughout the design and
manufacturing process, we gain insight into their future product requirements.

    QUICK-TURN PROTOTYPE AND PRE-PRODUCTION SERVICES.  We produce quick-turn
prototypes with lead times of three to fifteen days for the product development
groups of our customers. We also produce prototypes in pre-production quantities
with lead times of ten to fifteen days for these customers. While some
manufacturers offer prototypes through dedicated facilities, we differentiate
ourselves by offering volume production and prototypes within the same facility.
By using the same processing lines to manufacture prototypes, our prototypes
more accurately represent our volume products. This allows us to shorten the
time in transition from the development of prototype designs to volume
manufacturing and facilitates the volume delivery of high quality complex
printed circuit boards in a timely fashion. We believe this strengthens our
long-term relationships with customers and helps us gain an advantage in
securing both new quick-turn, pre-production and volume production programs.

    VOLUME PRODUCTION.  Volume production is characterized by standard lead
times of four to five weeks, as printed circuit boards move to full-scale
commercial production. At this stage of production, quality, on-time delivery,
process capability and price are the factors most important to our customers.
Our engineering capability enables us to produce, in volume, technologically
sophisticated printed circuit boards of 34 layers utilizing high performance
materials and leading edge fabrication techniques. In addition, our extensive
manufacturing process controls enable us to meet the accelerated time-to-market
and time-to-volume requirements of our customers. Our proprietary
computer-integrated manufacturing system tracks shop-floor production in real
time, delivering critical information to every decision point using online
statistical process control tools and helps us analyze and continually improve
our products and processes. We believe we consistently deliver dependable, high
quality printed circuit boards with an industry leading on-time delivery record.

    BACKPLANES AND BACKPLANE ASSEMBLIES.  We produce backplanes and provide
backplane assemblies to our customers. Backplanes are generally larger and
thicker printed circuit boards on which connectors are mounted to interconnect
printed circuit boards, integrated circuits and other electronic components.
Backplane assemblies are printed circuit boards on which various electronic
components, such as integrated circuits, capacitors, microprocessors and
resistors, have been mounted. In addition to providing backplane fabrication and
assembly services, we also perform radio frequency testing services to evaluate
the performance of backplane circuits across a spectrum of frequencies.

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

(a) Sales to contract manufacturers in fiscal year 1998 and thereafter are
    reflected as sales to the OEM served by the contract manufacturer.

    We supplied our products and services to 67 customers in the first six
months of fiscal 2000. Our five largest OEM customers during this period were
Cisco Systems, Hewlett-Packard, Motorola, Tektronix and Teradyne. Our five
largest OEM customers comprised 73.6%, 75.1% and 67.8% of our net sales during
fiscal 1997, 1998 and 1999, respectively. For the first six months of fiscal
2000, Cisco Systems, Motorola, Tektronix and Teradyne each accounted for more
than 10% of our net sales. Cisco Systems, Hewlett-Packard, Motorola and
Tektronix each accounted for more than 10% of our net sales in fiscal 1999.
Hewlett-Packard, Motorola and Tektronix each accounted for more than 10% of our
net sales in fiscal 1998.

    We also manufacture and sell our products to contract manufacturers that
assemble components on our products for resale to OEMs. Approximately 31.3%,
23.8% and 14.8% of our net sales were through contract manufacturers in fiscal
1999, 1998 and 1997, respectively. Our largest contract manufacturer customers
for the first six months of fiscal 2000 were Benchmark Electronics, Celestica,
SCI Systems and Solectron.

SALES AND MARKETING

    We market our products through a field-based direct sales force, field
application engineers, manufacturers' representative firms and customer service
personnel. As of November 30, 1999, we employed 27 sales and marketing
employees. We employ four field application engineers in regions across the U.S.
These field application engineers serve as the technical interface between Merix
and customers' design engineering teams. The field application engineers
integrate into the customers' design teams as technical experts, providing
information and modeling data to assure that the final printed circuit board
design meets electrical performance requirements, cost goals, and design
guidelines for manufacturability. We are also represented by four independent
manufacturers' representative firms in the United States.

    Our sales force develops close relationships with our OEM customers
beginning at the earliest development and design phases and continuing
throughout all stages of production. In addition, because contract manufacturers
are increasingly being given discretionary authority from OEMs to

                                       35
<PAGE>
award business to printed circuit board manufacturers, we also target contract
manufacturers as well as OEMs and leverage our relationships with OEMs to access
new business with contract manufacturers.

SUPPLIER RELATIONSHIPS

    We strive to develop and maintain good working relationships with our key
suppliers to enhance the operation of our business. We have established supplier
management programs to drive operational improvements and cost reductions. These
programs include periodic reviews with our suppliers in which we discuss joint
product and process development. In addition, suppliers participate in meetings
with our customers to gain a better understanding of our material requirements.
We also have on-site representatives from our suppliers that monitor material
requirements and usage and help us drive improvements in our manufacturing
process.

    We have entered into strategic relationships with certain suppliers of
laminates, raw materials and services to reduce lead times and inventory
carrying costs, enhance the quality and reliability of the supply of raw
materials and reduce transportation and other logistics costs. For example,
Matsushita Electronics Materials, a key laminate supplier, operates an 82,000
square foot factory producing standard and high performance laminates adjacent
to our facility. Isola Laminate Systems Corp., another laminate supplier,
utilizes an independent warehouse distribution center adjacent to our facility
to offer just-in-time delivery of high-performance raw materials. In addition,
Probe Test Services, a wholly-owned subsidiary of Mania Technologies, Inc.
(USA), provides on-site electrical test services at our facility.

MANUFACTURING AND TECHNOLOGY

    The increasing complexity of electronic products has driven technological
advancements in interconnect products and has placed increasingly more difficult
demands on the manufacturing process. We have invested in production technology
to manufacture dense multilayer printed circuit boards utilizing advanced
fabrication processes and high performance materials in volume production. We
employ numerous advanced manufacturing techniques and systems, including
dry-film imaging, automated optical inspection, computer controlled lamination,
computer controlled drilling and routing, multi-purpose metal plating,
photoimageable solder mask processing, dual-access electrical testing, and
surface coating. Our execution of these techniques enables us to manufacture
complex printed circuit boards of consistent quality in high-volume and on a
timely basis.

    In general, we receive circuit designs directly from our customers in the
form of computer data files, which we review to ensure data accuracy and product
manufacturability. Using these computer files, we generate images of the circuit
patterns that we develop on individual layers using advanced photographic
processes. Through a variety of plating and etching processes, we selectively
add and remove conductive materials forming horizontal layers of thin traces or
circuits, which are separated by insulating material. A finished multilayer
circuit board laminates together a number of layers of circuitry, using intense
heat and pressure under vacuum. Vertical connections between layers are achieved
by plating through small holes called vias. Vias are made by highly specialized
drilling equipment capable of achieving extremely fine tolerances with high
accuracy. We specialize in high layer printed circuit boards with extremely fine
geometries and tolerances. Because of the tolerances involved, we use clean
rooms in certain manufacturing processes where tiny particles might otherwise
create defects on the circuit patterns, and use automated optical inspection
systems to ensure consistent quality.

    To organize and track our orders, materials and processes, we have developed
a proprietary computer-integrated manufacturing system called the Computer
On-Line Loading and Tracking

                                       36
<PAGE>
system. This system tracks all phases and aspects of shop-floor production in
real time, delivering crucial information to every decision point using online
statistical process control tools. We believe this system provides us with a
competitive advantage through its high level of automation and integration in
support of our business processes.

    Although we seek to protect certain proprietary technology and other
intangible assets through patents, we have relatively few patents and believe
our business depends on our effective execution of fabrication techniques and
our ability to improve our manufacturing processes to meet evolving industry
standards. In addition, because manufacturing printed circuit boards requires
our employees to have sufficient know-how to operate advanced equipment and to
conduct sensitive and complicated manufacturing processes, we depend to a large
extent on training, recruiting and retaining these employees.

    We were recently chosen to participate in the Advanced Embedded Passive
Technology Consortium sponsored by the National Center for Manufacturing
Sciences. This consortium was designed to develop new materials, tools and
manufacturing techniques for embedding the majority of passive electrical
devices, such as resistors and capacitors, into the structure of a printed
circuit board. This new technology should reduce costs and space requirements
and improve the reliability and performance of many electrical devices. We
believe our participation in this project will help us maintain our technology
leadership and provide us with additional funding for our engineering research
in this area of interconnect product development.

FACILITIES

    We manufacture all of our products on our 73-acre Forest Grove campus, which
includes a 215,000 square foot manufacturing facility and a 62,000 square foot
training and administration facility. Our manufacturing facility is ISO 9002
certified, and we use total quality management systems to meet the highest
industry standards for product quality.

    In the third quarter of fiscal 1998, we commenced an expansion plan for our
Forest Grove facility to increase our production capacity and our technological
capabilities. This plan consisted of three phases. The first phase, which cost
approximately $20.0 million, involved converting non-manufacturing space to
manufacturing space and adding new equipment. This phase was completed at the
end of fiscal 1999. Our second phase involved transferring equipment from our
Loveland facility to Forest Grove and was completed in December 1999 with an
installation cost of approximately $2.0 million. The third phase, which we
expect to cost approximately $25.0 million, will involve increasing plant
capacity over the next two years through the addition of new equipment and
square footage to our Forest Grove facility. We expect this expansion to
increase our production capacity by approximately 30%.

COMPETITION

    We believe our major competitors are the large U.S. and international
independent producers that also manufacture multilayer printed circuit boards
and provide backplane and other electronic assemblies, such as Hadco, Honeywell,
Multek (a division of DII Group), Sanmina, Tyco International and Viasystems. We
believe our ability to compete successfully depends upon a number of factors,
including our responsiveness to customers in delivery and service, our
technological capability; our product quality; and our pricing.

BACKLOG

    Our 90-day backlog was approximately $22.5 million at November 30, 1999,
$18.0 million at the end of fiscal 1999 and $15.8 million at the end of fiscal
1998. A substantial portion of our backlog is typically scheduled for delivery
within 60 days. If a customer cancels or postpones an order, we

                                       37
<PAGE>
may charge the customer a fee that varies depending upon the time of
cancellation or postponement. A substantial portion of our backlog is subject to
cancellation or postponement without significant penalty.

EMPLOYEES

    As of November 30, 1999 we had a total of 1,195 employees, of which 1,064
were regular employees and 131 were temporary agency employees. None of our
employees is represented by a labor union. We have never experienced an
employee-related work stoppage. We believe our relationship with our employees
is good.

ENVIRONMENTAL MATTERS

    We are required to comply with federal, state, county and municipal
regulations regarding protection of the environment. Printed circuit board
manufacturing requires the use of a variety of materials, including metals and
chemicals. As a result, we are subject to environmental laws relating to the
storage, use and disposal of chemicals, solid waste, and other hazardous
materials, as well as air quality regulations. Water used in the manufacturing
process must be treated to remove heavy metals and neutralized before it can be
discharged into the municipal sanitary sewer system. We operate and maintain
effluent water treatment systems and utilize approved laboratory testing
procedures at our manufacturing facility under effluent discharge permits issued
by authorized governmental agencies. These permits must be renewed periodically
and are subject to revocation in the event of violations of environmental laws.
Certain waste materials and byproducts generated by our manufacturing processes
are sent to approved third parties for recycling, reclamation, treatment or
disposal. We believe our environmental management complies with environmental
protection requirements in all material respects.

LEGAL PROCEEDINGS

    We are not currently involved in any threatened or pending litigation. From
time to time we may be involved in litigation arising in the normal course of
our business.

consummation of our initial public offering. Tektronix transferred to Merix all
of the assets used exclusively in its circuit board business and approximately
$17.5 million in cash in exchange for 6,000,000 shares of our common stock and a
note in the principal amount of $10.0 million. The note we issued to Tektronix
bears interest at the rate of 7.5% per annum and was originally payable over
five years. We granted Tektronix a security interest in our real property to
secure repayment of the note. In 1999 this note was amended to provide for
payment of accrued interest only in May 1999, in the amount of $171,920, and
payment in each of June 2000 and 2001 of $1.1 million in principal plus accrued
interest. Tektronix may set off any amounts not paid by Merix when due under the
note against any amounts Tektronix or its subsidiaries owe Merix under any
supply agreements.

    Our asset transfer agreement with Tektronix provided that we would use all
reasonable efforts to nominate and maintain two individuals designated by
Tektronix and three additional independent individuals as members of our Board
of Directors so long as Tektronix held at least 25% of the outstanding shares of
our Common Stock. For fiscal 2000 Tektronix has nominated only Mr. Neun pursuant
to the agreement. After completion of this offering, we will no longer be
required to nominate and maintain any Tektronix nominees on our Board of
Directors.

    Pursuant to a registration rights agreement, dated June 1, 1994, Tektronix
may demand, on two occasions, that we use our best efforts to register all or a
portion of the 6,000,000 shares of our stock issued to Tektronix in 1994 for
public resale. Tektronix also has "piggyback rights" with respect to the shares,
which allows Tektronix to require that we include all or a portion of the shares
in a registration under the Securities Act. After this offering Tektronix will
continue to have its demand and piggyback registration rights.

    Tektronix is a significant customer of Merix. During fiscal 1999, our net
sales to Tektronix were $15.7 million, or 13.8%. In addition, Tektronix and we
were parties to waste management and services agreements covering certain
environmental matters. During fiscal 1999, we paid $90,000 to Tektronix under
these agreements.

required to make relating to these liabilities.

OVER-ALLOTMENT OPTIONS

    We and the selling shareholder have granted 30-day over-allotment options to
the underwriters to purchase up to 300,000 and 150,000 additional shares of
common stock, respectively, at the public offering price less the underwriting
discount and commissions as shown on the cover page of this prospectus. If the

INFORMATION REGARDING THOMAS WEISEL PARTNERS LLC

MARKET STABILIZATION, SHORT POSITIONS AND PENALTY BIDS

    To facilitate this offering, persons participating in the offering may
engage in transactions that stabilize, maintain or otherwise affect the price of
the common stock during and after this offering. Specifically, the underwriters
may over-allot or otherwise create a short position in the common stock for
their own account by selling more shares of common stock than we have sold to
them. The underwriters may elect to cover any short position by purchasing
shares of common stock in the open market or by exercising the over-allotment
options granted to the underwriters. In addition, the underwriters may stabilize
or maintain the price of the common stock by bidding for or purchasing shares of
common stock in the open market and may impose penalty bids. Under these penalty
bids, selling concessions that are allowed to syndicate members or other
broker-dealers participating in this offering are reclaimed if shares of common
stock previously distributed in this offering are repurchased, usually to
stabilize the market. The effect of these transactions may be to stabilize or
maintain the market price at a level above that which might otherwise prevail in
the open market. No representation is made as to the magnitude or effect of any
stabilization or other transactions. These transactions may be affected on the
Nasdaq National Market or otherwise and may be discontinued at any time after
they are commenced.

                       REPORT OF INDEPENDENT ACCOUNTANTS

                               MERIX CORPORATION

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors and Shareholders of
Merix Corporation

    We have audited the accompanying balance sheets of Merix Corporation as of
May 30, 1998 and May 29, 1999 and the related statements of operations,
shareholders' equity, and cash flows for the years ended May 31, 1997, May 30,
1998 and May 29, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.

                         NOTES TO FINANCIAL STATEMENTS

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

ALL INFORMATION SUBSEQUENT TO MAY 31, 1999 AND INFORMATION FOR THE SIX MONTHS
ENDED NOVEMBER 30, 1998 AND NOVEMBER 30, 1999 IS UNAUDITED.

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

    Merix Corporation (the Company or Merix), an Oregon corporation, was formed
in March 1994 to succeed the business conducted by the Circuit Board Division of
Tektronix, Inc. (Tektronix). On June 1, 1994, the Company acquired the assets
and assumed certain liabilities of the division in connection with the initial
public offering of its common stock, and began to operate as an independent
corporation.

BUSINESS

    The Company is a leading manufacturer of technologically advanced electronic
interconnect solutions for use in sophisticated electronic equipment. The
Company's principal products are complex multilayer printed circuit boards,
which are the basic platforms used to interconnect microprocessors, integrated
circuits and other components that are essential to the operation of electronic
products and systems. The Company provides solutions to original equipment
manufacturers and contract manufacturers in various segments of the electronics
industry, including the communications, computer, and test and measurement
segments. The Company provides its customers with a broad range of products and
services including quick-turn prototypes, volume and pre-production of printed
circuit boards as well as backplanes and backplane assemblies.

FISCAL YEAR

    The Company's fiscal year is the 52 or 53-week period ending the last
Saturday in May. Fiscal year 1999 was a 52-week year ending May 29, fiscal year
1998 was a 52-week year ended May 30 and fiscal year 1997 was a 53-week year
ended May 31. For convenience, all of the Company's fiscal years are presented
as ended on May 31, and all interim periods are presented as ended on the last
day of the last calendar month of the period.

UNAUDITED INTERIM FINANCIAL INFORMATION

    All information subsequent to May 31, 1999 is unaudited. In the opinion of
management, the unaudited interim financial statements as of November 30, 1998
and November 30, 1999 and for the six month periods then ended have been
prepared on the same basis as the annual financial statements and reflect all
adjustments that are necessary for the fair presentation of results for the
periods shown. The results of operations for such periods are not necessarily
indicative of the results expected for the full fiscal year or for any interim
period.

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 sales and expenses during the reporting
period. Actual results could differ from those estimates.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
BALANCE SHEET FINANCIAL INSTRUMENTS: FAIR VALUES

    The carrying amounts reported in the balance sheet for investments, accounts
receivable and accounts payable approximate fair value because of the immediate
or short-term maturity of these financial instruments. The carrying amount for
long-term debt approximates its fair value because the related interest rates
are comparable to rates currently available to the Company for debt with similar
terms and maturities.

CASH AND CASH EQUIVALENTS

    Cash and cash equivalents are comprised of cash in banks and highly liquid
investments with maturities of three months or less when purchased.

SHORT-TERM INVESTMENTS

    The Company classifies securities at acquisition into one of three
categories: held to maturity, available for sale, or trading. At May 31, 1998
and 1999, all of the Company's investments with original maturities of more than
90 days were classified as held to maturity and valued at amortized cost.

INVENTORIES

    Inventories are valued at the lower of cost or market and include materials,
labor and manufacturing overhead. Cost is determined on the first-in, first-out
(FIFO) basis.

PROPERTY AND DEPRECIATION

    Property, plant and equipment is carried at cost less accumulated
depreciation. Costs of improvements, including interest, are capitalized.
Depreciation is calculated based on the estimated useful lives of depreciable
assets as follows: 40 years for buildings, 10 to 20 years for grounds, 3 to
7 years for machinery and equipment, and is provided using the straight-line
method.

LONG-LIVED ASSETS

    The Company's long-lived assets are reviewed for impairment when
circumstances indicate that the carrying amount may not be recoverable. If the
sum of expected undiscounted future cash flows is less than the carrying amount
of the asset, a loss is recognized.

GOODWILL

    The cost of goodwill is amortized on a straight-line basis over the
estimated period benefited of 15 years. Goodwill amortization for fiscal years
1997, 1998 and 1999 was $169, $167, and $41, respectively.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION

    Revenue from product sales is recognized at the time of shipment. Service
revenue is recognized as services are provided.

ENGINEERING EXPENSE

    Expenditures for engineering of products and manufacturing processes are
expensed as incurred.

WARRANTY

    The Company generally warrants its products for a period of up to four
months from shipment. Accordingly, a provision for the estimated cost of the
warranty is recorded upon shipment.

NET INCOME (LOSS) PER SHARE

    Basic net income (loss) per share is computed using the weighted average
number of shares of common stock outstanding for the period. Diluted income per
share is computed using the weighted average number of shares of common stock
and dilutive common equivalent shares related to stock options outstanding
during the period. Incremental shares, related to outstanding stock options of
114,061 and 78,501 for fiscal years 1997 and 1998 and 183,002 for the six months
ended November 30, 1999 were included in the calculations of diluted net income
per share.

    Diluted net loss per share is computed using the weighted average number of
shares of common stock outstanding for the period. Stock options to purchase
1,247,302 shares for the six months ended November 30, 1998 and 1,260,890 shares
for fiscal year 1999 were not included in the net loss per share calculations,
because to do so would have been antidilutive. Of the stock options outstanding
at November 30, 1999, 188,890 had exercise prices above the market price of the
underlying common stock at that date.

COMPREHENSIVE INCOME (LOSS)

    The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 130, "Reporting Comprehensive Income" which establishes requirements for
reporting comprehensive income (loss) in financial statements. Comprehensive
income (loss) as defined, includes all changes in equity during a period from
non-owner sources. The Company has not had any transaction that are required to
be reported in comprehensive (loss) income in the periods presented, except for
net income (loss).

INCOME TAXES

    The Company accounts for income taxes under the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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 income in the period that includes the enactment date.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amounts expected to be realized.

SEGMENT REPORTING

    The Company has adopted SFAS No. 131, "Disclosures About Segments of an
Enterprise and Related Information" (SFAS 131). Based on definitions contained
within SFAS 131, the Company has determined that it operates within one segment.
Additionally, the Company has no material revenues from external customers
outside the United States and has no long-lived assets outside the United
States. See Note 11 for information regarding significant customers.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB No. 25") and complies with the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation." Under APB No. 25, compensation expense is based on the
difference, if any, on the date of grant, between the exercise price of the
instrument granted and the fair value of the underlying stock.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (SFAS 133). SFAS 133 establishes accounting
and reporting standards requiring every derivative instrument be recorded in the
balance sheet as either an asset or liability measured at its fair value.
SFAS 133 also requires changes in the derivative's fair value be recognized
currently in results of operations unless specific hedge accounting criteria are
met. SFAS 133, as amended by SFAS 137, is effective for fiscal years beginning
after June 15, 2000. The Company does not expect SFAS 133 to have a material
impact on its financial statements.

NOTE 2. RESTRUCTURING

    In the first quarter of fiscal 1999, the Company implemented a restructuring
plan designed to improve capacity utilization and lower its cost structure. The
Company closed its Loveland, Colorado facility in October 1998 and laid off
approximately 340 manufacturing and support employees located there, sold its
Soladyne facility in San Diego, California and laid off approximately 35
employees from administrative, engineering and support functions at its Forest
Grove, Oregon location. The Company also transferred a portion of the
manufacturing equipment used in the Loveland facility to its Forest Grove site.
Installation of the manufacturing equipment was completed in December 1999.

NOTE 2. RESTRUCTURING (CONTINUED)
    In the third quarter of fiscal 1999, the Company reversed $7,109 of the
restructuring expense taken in the first quarter of fiscal 1999, primarily
because lease termination costs at Loveland were $3,059 less than the Company
had anticipated, the Company was able to realize a higher value on inventory
than it had previously written down and it realized $2,826 more from the sale of
equipment at the Soladyne facility than it had expected. The Company also spent
less on severance benefits than it expected.

    The components of the restructuring expense, and the subsequent reversal,
were as follows:

    Cash proceeds from asset sales of $4.8 million are reflected in the amounts
shown above for write-down and write-off of manufacturing equipment and
inventory. All cash payments for severance benefits, lease termination costs and
other costs related to the restructuring expense were paid in fiscal 1999. As of

restructuring plan.

    In the second quarter of fiscal year 1998, the Company recorded a $1,878
charge for the costs associated with a restructuring plan undertaken to improve
the Company's profitability, which included a work force reduction, the
write-off of certain manufacturing equipment and other miscellaneous costs. All
liabilities associated with the restructuring plan were paid in the third
quarter of fiscal year 1998.

NOTE 3. CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of trade accounts receivable and investments.
In total, six customers represented approximately 73% of the accounts receivable
balance at May 31, 1999, individually ranging from 5% to 19%. The risk in trade
accounts receivable is limited due to the creditworthiness of companies
comprising the Company's customer base and their dispersion across many
different

sectors of the electronics industry and geographies. The Company has not had
significant losses related to its accounts receivable in the past. The risk in
investments is limited due to the creditworthiness of investees comprising the
portfolio and the diversity of the portfolio. The Company does not believe that
at May 31, 1999, and at November 30, 1999, it had any significant credit risks.

affiliated with Merix or Tektronix of 20,000 shares at the time first elected to
the board and 5,000 shares annually thereafter. The options generally become
exercisable ratably over a four-year period beginning one year after the date of
grant and expire ten years after the date of grant.

    The Company's Board of Directors approved a plan which allowed employees,
except executive officers, to reprice existing stock options to the fair market
value of the underlying stock on June 30, 1998. Under the plan, employees
received nine options in exchange for every 10 options they elected to reprice.
The vesting schedule and term of repriced options remained the same as the
original option. During fiscal year 1999, options to purchase 332,820 shares at
a weighted average price per share of $18.39 were exchanged for options to
purchase 298,977 shares at a weighted average price per share of $9.94.

    Restricted stock awards are subject to vesting and other terms as specified
at the time of issuance by a committee of the Board of Directors. Generally,
restricted stock awards vest ratably over a three-year period beginning on the
first anniversary of their issuance. Unearned compensation expense is recognized
ratably over the vesting period. There were no restricted stock awards in fiscal
years 1998 or 1999. The weighted average per share fair value of restricted
stock awards issued was $18.79 in fiscal year 1997.

    SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS 123) defines a
fair value based method of accounting for employee stock options and similar
equity instruments and encourages all entities to adopt that method of
accounting for all of their employee stock compensation plans. However, it also
allows an entity to continue to measure compensation cost for those plans using
the method of accounting prescribed by Accounting Principles Board Opinion
No. 25 (APB 25). Entities electing to remain with the accounting in APB 25 must
make pro forma disclosures of net income (loss) and, if presented, net income
(loss) per share, as if the fair value based method of accounting defined in
SFAS 123 had been adopted.

    The Company has elected to account for its stock-based compensation plans
under APB 25; however, the Company has computed, for pro forma disclosure
purposes, the value of all stock

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    As an Oregon corporation, the Registrant is subject to the laws of the State
of Oregon governing private corporations and the exculpation from liability and
indemnification provisions contained therein. Pursuant to
Section 60.047(2)(d) of the Oregon Revised Statutes ("ORS"), the Registrant's
Second Restated Articles of Incorporation (the "Articles") eliminates the
liability of the Registrant's directors to the Registrant or its shareholders
except for any liability related to (i) breach of the duty of loyalty;
(ii) acts or omissions not in good faith or that involve intentional misconduct
or a knowing violation of law; (iii) any unlawful distribution under ORS 60.367;
or (iv) any transaction from which the director derived an improper personal
benefit.

    ORS Section 60.391 allows corporations to indemnify their directors and
officers against liability where the director or officer has acted in good faith
and with a reasonable belief that actions taken were in the best interests of
the corporation or at least not opposed to the corporation's best interests and,
if in a criminal proceeding, the individual had no reasonable cause to believe
the conduct in question was unlawful. Under ORS Sections 60.387 to 60.414,
corporations may not indemnify a director or officer against liability in
connection with a claim by or in the right of the corporation or for any
improper personal benefit in which the director or officer was adjudged liable
to the corporation. ORS Section 60.394 mandates indemnification for all
reasonable expenses incurred in the successful defense of any claim made or
threatened whether or not such claim was by or in the right of the corporation.
Finally, pursuant to the ORS Section 60.401, a court may order indemnification
in view of all the relevant circumstances, whether or not the director or
officer met the good-faith and reasonable belief standards of conduct set out in
ORS Section 60.391.

    ORS Section 60.414 also provides that the statutory indemnification
provisions are not deemed exclusive of any other rights to which directors or
officers may be entitled under a corporation's articles of incorporation or
bylaws, any agreement, general or specific action of the board of directors,
vote of shareholders, or otherwise.

    The Articles provide that the Registrant is required to indemnify to the
fullest extent not prohibited by law any current or former director who is made,
or threatened to be made, a party to an action or proceeding by reason of the
fact that such person serves or served as a director of the Registrant. The
Articles also provide that the Registrant is permitted to indemnify to the
fullest extent not prohibited by law any current or former officer who is made,
or threatened to be made, a party

                                      II-1

to an action or proceeding by reason of the fact that such person is or was an
officer of the Registrant.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 above, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

    The undersigned registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.

        (2) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

Merix and its shareholders. In this connection, Merix recognizes that, as is the
case with many publicly held corporations, the possibility of a change of
control may exist and that such possibility, and the uncertainty and questions
which it may raise among management, may result in the departure or distraction
of management personnel to the detriment of Merix and its shareholders. In order
to induce Executive to remain employed by Merix in the face of uncertainties
about the long-term strategies of Merix and possible change of control of Merix
and their potential impact on Executive's position with Merix, this Agreement,
which has been approved by the Board of Directors of Merix, sets forth the
severance benefits that Merix will provide to Executive in the event Executive's
employment by Merix is terminated under the circumstances described in this
Agreement.

1.   EMPLOYMENT RELATIONSHIP. Executive is currently employed by Merix as Vice
President Operations. Executive and Merix acknowledge that either party may
terminate this employment relationship at any time and for any or no reason,
subject to the obligation of Merix to provide the severance benefits specified
in this Agreement in accordance with the terms hereof.

2.   RELEASE OF CLAIMS. In consideration for and as a condition precedent to
receiving the severance benefits outlined in this Agreement, Executive agrees to
execute a Release of Claims in the appropriate form attached as Exhibit A
("Release of Claims"). Executive promises to execute and deliver the Release of
Claims to Merix within the later of (a) 45 days from the date Executive receives
the Release of Claims or (b) the last day of Executive's active employment.

3.   COMPENSATION UPON TERMINATION. In the event of a Termination of Executive's
Employment (as defined in Section 8.1) at any time other than for Cause (as
defined in Section 8.2 of this Agreement), death or Disability (as defined in
Section 8.4 of this Agreement), and contingent upon Executive's execution of the
Release of Claims and compliance with Section 10, Executive shall be entitled to
the following benefits:

Merix Corporation

3.1  As severance pay and in lieu of any other compensation for periods
subsequent to the date of termination, Merix shall pay Executive, in a single
payment after employment has ended and eight days have passed following
execution of the Release of Claims without revocation, an amount in cash equal
to one year of Executive's annual base pay at the rate in effect immediately
prior to the date of termination.

3.2  Executive is entitled to extend coverage under any group health plan in
which Executive and Executive's dependents are enrolled at the time of
termination of employment under the COBRA continuation laws for the 18-month
statutory period, or so long as Executive remains eligible under COBRA. Merix
will pay Executive a lump sum payment in an amount equivalent to the reasonably
estimated cost Executive may incur to extend for a period of 18 months under the
COBRA continuation laws Executive's group health and dental plan coverage in
effect at the time of termination. Executive may use this payment, as well as
any payment made under Section 3.1, for such COBRA continuation coverage or for
any other purpose.

3.3  Executive shall be entitled to a portion of the benefits under any annual
cash incentive plans in effect at the time of termination equal to the greater
of (a) 50 percent of Executive's target benefit under such plan for the year or
(b) a prorated amount representing the portion of the plan year during which
Executive was a participant. For purposes of this Agreement, Executive's
participation in any such plan will be considered to have ended on Executive's
last day of active employment. In making the proration calculation, the amount
of Executive's award if Executive had been a participant for the full incentive
period shall be divided by the total number of days in the incentive period and
the result multiplied by the actual number of days Executive participated in the
plan. The payment amount shall be calculated at the end of the incentive period
and the amount shall not be due and payable by Merix to Executive until the date
that all awards are payable to other eligible employees after the close of the
incentive period, except that Executive may elect at any time after termination,
by written notice to Merix, to receive 50 percent of Executive's target benefit
instead of the prorated amount, in which case the payment shall be made within
20 days of such election. If the applicable plan provides for a greater payment
for a participant whose employment terminates prior to the end of an incentive
period, the applicable plan payment shall be made.

3.4  Merix will pay up to $12,500 to a third party outplacement firm selected by
Executive to provide career counseling assistance to Executive for a period of
one year following Executive's termination date. Executive may elect to receive
the $12,500 in cash in lieu of payment to a third party outplacement firm.

3.5  All outstanding stock options, restricted stock, stock bonuses or other
stock awards shall be governed by the terms of the applicable agreement or plan.

3.6  In the event that Executive's employment with Merix terminates for any
reason prior to a Change of Control (as defined in Section 8.3), other than at
the direction of a person who has entered into an agreement with Merix, the
consummation of which will constitute a Change of Control, Executive shall not
be entitled to benefits under Section 4 of this Agreement.

4.   ADDITIONAL COMPENSATION UPON TERMINATION FOLLOWING A CHANGE OF CONTROL. In
the event of a Termination of Executive's Employment other than for Cause, death
or Disability within 24 months following a Change of Control, or prior to a
Change of Control at the direction of a person who has entered into an agreement
with Merix, the consummation of which will constitute a Change of Control, and
contingent upon Executive's execution of the Release of Claims and compliance
with Sections 5 and 10, Executive shall be entitled to the following benefits,
which benefits shall be in addition to the benefits provided in Section 3:

4.1  Merix shall pay Executive, in a single payment within the latter of (a)
eight days after the last day of employment, including employment during the up
to the six months employment period referred to in Section 5 if Merix or the
surviving company has requested Executive to continue employment during such
period and (b) eight days after execution of the Release of Claims without
revocation, an amount in cash equal to one year of Executive's annual base
compensation at the rate in effect immediately prior to the date of termination.

4.2  Executive shall be entitled to receive an amount such that the amount
payable pursuant to Section 3.3 plus the amount payable pursuant to this Section
4.2 equals 100 percent of the Executive's target benefit for the year under
annual cash incentive plans in effect at the time of termination. The amount
payable pursuant to Section 4.2 shall be paid on the same date that the Section
4.1 payment is payable.

4.3  Merix shall maintain in full force and effect, at its sole cost and
expense, for Executive's continued benefit for a period terminating 18 months
after the date of termination a life insurance policy insuring Executive's life
with coverage equal to two times Executive's annual base pay in effect
immediately prior to termination, provided that Executive's continued
participation is possible under the general terms and provisions of such policy.
At Executive's election or in the event that Executive's continued participation
in such policy is barred, Merix shall make a lump sum payment to Executive equal
to the total premiums that would have been paid by Merix for such 18 month
period. The maximum amount that Merix shall be obligated to pay pursuant to this
Section 4.3 in premiums and payments to Executive shall be $5,000.

4.4  The possibility of forfeiture to Merix of all stock issued to Executive
under all Executive Stock Bonus Agreements shall immediately lapse.

4.5  All outstanding stock options held by Executive under all stock option and
stock incentive plans of Merix shall become immediately exercisable in full and
shall remain exercisable until the earlier of (a) two years after termination of
employment or (b) the option expiration date as set forth in the applicable
option agreement.

4.6  Notwithstanding any provision in this Agreement, in the event that
Executive would receive a greater after-tax benefit from the Capped Benefit (as
defined in the next sentence) than from the payments pursuant to this Agreement
(the "Specified Benefits"), the Capped Benefit shall be paid to Executive and
the Specified Benefits shall not be paid. The Capped Benefit is the Specified
Benefits, reduced by the amount necessary to prevent any portion of the
Specified Benefits from being "parachute payments" as defined in section
280G(b)(2) of the Internal Revenue Code of 1986, as amended ("IRC"), or any
successor provision. For purposes of determining whether Executive would receive
a greater after-tax benefit from the Capped Benefit than from the Specified
Benefits, there shall be taken into account all payments and benefits Executive
will receive upon a change in control of the Company (collectively, excluding
the Specified Benefits, the "Change of Control Payments"). To determine whether
Executive's after-tax benefit from the Capped Benefit would be greater than
Executive's after-tax benefit from the Specified Benefits, there shall be
subtracted from the sum of the before-tax Specified Benefits and the Change of
Control Payments (including the monetary value of any non-cash benefits) any
excise tax that would be imposed under IRC ss. 4999 and all federal, state and
local taxes required to be paid by Executive in respect of the receipt of such
payments, assuming that such payments would be taxed at the highest marginal
rate applicable to individuals in the year in which the Specified Benefits are
to be paid or such lower rate as Executive advises Merix in writing is
applicable to Executive.

5.   ADDITIONAL SERVICE. Executive agrees that, if requested by Merix or the
surviving company following a Change of Control, Executive will continue his or
her employment with Merix or the surviving company for a period of up to six
months following the Change of Control in any capacity requested by Merix or the
surviving company consistent with Executive's areas of professional expertise.
During this period Executive shall receive the same salary and substantially the
same benefits as in effect prior to the Change of Control. Executive shall not
be entitled to any benefits provided by Section 4 if Executive fails to perform
in accordance with this Section 5.

6.   TAX WITHHOLDING; SUBSEQUENT EMPLOYMENT.

6.1  All payments provided for in this Agreement are subject to applicable tax
withholding obligations imposed by federal, state and local laws and
regulations.

6.2  The amount of any payment provided for in this Agreement shall not be
reduced, offset or subject to recovery by Merix by reason of any compensation
earned by Executive as the result of employment by another employer after
termination.

7.   OTHER AGREEMENTS. This Agreement replaces and supersedes the Executive
Severance Agreement dated June 1, 1994 between Executive and Merix. In the event
that severance benefits are payable to Executive under any other agreement with
Merix in effect at the time of termination (including but not limited to any
employment agreement, but excluding for this purpose any stock option agreement
or stock bonus agreement or stock appreciation right agreement that may provide
for accelerated vesting or related benefits upon the occurrence of a change in
control), the benefits provided in this Agreement shall not be payable to
Executive. Executive may, however, elect to receive all of the benefits provided
for in this Agreement in lieu of all of the benefits provided in all such other
agreements. Any such election shall be made with respect to the agreements as a
whole, and Executive cannot select some benefits from one agreement and other
benefits from this Agreement.

8.   DEFINITIONS.

8.1  TERMINATION OF EXECUTIVE'S EMPLOYMENT. Termination of Executive's
Employment means that Merix has terminated Executive's employment with Merix
(including any subsidiary of Merix). For purposes of Section 3, if Executive is
assigned additional or different titles, tasks or responsibilities from those
currently held or assigned, consistent with Executive's areas of professional
expertise and with no decrease in annual base compensation, whether at Merix or
any subsidiary of Merix, such circumstances shall not constitute a Termination
of Executive's Employment. For purposes of Section 4, Termination of Executive's
Employment shall include termination by Executive, within 24 months of a Change
of Control, by written notice to Merix referring to the applicable paragraph of
Section 8.1, for "Good Reason" based on:

                    (a) the assignment to Executive of a different title, job or
               responsibilities that results in a decrease in the level of
               responsibility of Executive with respect to the surviving company
               after the Change of Control when compared to Executive's level of
               responsibility for Merix' operations prior to the Change of
               Control; provided that Good Reason shall not exist if Executive
               continues to have the same or a greater general level of
               responsibility for the former Merix operations after the Change
               of Control as Executive had prior to the Change of Control even
               if the former Merix operations are a subsidiary or division of
               the surviving company;

                    (b) a reduction by Merix or the surviving company in
               Executive's base pay as in effect immediately prior to the Change
               of Control;

                    (c) a significant reduction by Merix or the surviving
               company in total benefits available to Executive under cash
               incentive, stock incentive and other employee benefit plans after
               the Change of Control compared to the


5

<PAGE>
Merix Corporation

               total package of such benefits as in effect prior to the Change
               of Control;

                    (d) Merix or the surviving company requires Executive to be
               based more than 50 miles from where Executive's office is located
               immediately prior to the Change of Control except for required
               travel on company business to an extent substantially consistent
               with the business travel obligations which Executive undertook on
               behalf of Merix prior to the Change of Control; or

                    (e) the failure by Merix to obtain from any successor
               (whether direct or indirect, by purchase, merger, consolidation
               or otherwise) to all or substantially all of the business and/or
               assets of Merix ("Successor") the assent to this Agreement
               contemplated by Section 9 hereof.

8.2  CAUSE. Termination of Executive's Employment for "Cause" shall mean
termination upon (a) the willful and continued failure by Executive to perform
substantially Executive's reasonably assigned duties with Merix (other than any
such failure resulting from Executive's incapacity due to physical or mental
illness) after a demand for substantial performance is delivered to Executive by
the Board, the Chief Executive Officer or the President of Merix which
specifically identifies the manner in which the Board or Merix believes that
Executive has not substantially performed Executive's duties or (b) the willful
engaging by Executive in illegal conduct which is materially and demonstrably
injurious to Merix. No act, or failure to act, on Executive's part shall be
considered "willful" unless done, or omitted to be done, by Executive without
reasonable belief that Executive's action or omission was in, or not opposed to,
the best interests of Merix. Any act, or failure to act, based upon authority
given pursuant to a resolution duly adopted by the Board or based upon the
advice of counsel for Merix shall be conclusively presumed to be done, or
omitted to be done, by Executive in the best interests of Merix.

8.3  CHANGE OF CONTROL. A Change of Control shall mean that one of the following
events has taken place:


                    (a) The shareholders of Merix approve one of the following
               ("Approved Transactions"):

                         (i) Any merger or statutory plan of exchange involving
                    Merix ("Merger") in which Merix is not the continuing or
                    surviving corporation or pursuant to which Common Stock
                    would be converted into cash, securities or other property,
                    other than a Merger involving Merix in which the holders of
                    Common Stock immediately prior to the Merger have the same
                    proportionate ownership of Common Stock of the surviving
                    corporation after the Merger; or


6

<PAGE>
Merix Corporation

                         (ii) Any sale, lease, exchange, or other transfer (in
                    one transaction or a series of related transactions) of all
                    or substantially all of the assets of Merix or the adoption
                    of any plan or proposal for the liquidation or dissolution;

                    (b) A tender or exchange offer, other than one made by (i)
               Merix or (ii) Tektronix, Inc. at a time when Merix is in default
               under any of the Supply Agreements between Tektronix or any of
               its subsidiaries and Merix, is made for Common Stock (or
               securities convertible into Common Stock) and such offer results
               in a portion of those securities being purchased and the offeror
               after the consummation of the offer is the beneficial owner (as
               determined pursuant to Section 13(d) of the Securities Exchange
               Act of 1934, as amended (the "Exchange Act")), directly or
               indirectly, of securities representing at least 20 percent of the
               voting power of outstanding securities of Merix;

                    (c) Merix receives a report on Schedule 13D of the Exchange
               Act reporting the beneficial ownership by any person (other than
               Tektronix, Inc. or any of its affiliates) of securities
               representing 20 percent or more of the voting power of
               outstanding securities of Merix, except that (i) if such receipt
               shall occur as the result of sale of Common Stock (or securities
               convertible into Common Stock) by Tektronix, Inc. or any of its
               affiliates, it shall not constitute a Change of Control, or (ii)
               if such receipt shall occur during a tender offer or exchange
               offer described in (b) above, a Change of Control shall not take
               place until the conclusion of such offer; or

                    (d) During any period of 12 months or less, individuals who
               at the beginning of such period constituted a majority of the
               Board of Directors cease for any reason to constitute a majority
               thereof unless the nomination or election of such new directors
               was approved by a vote of at least two-thirds of the directors
               then still in office who were directors at the beginning of such
               period.

Notwithstanding anything in the foregoing to the contrary, no Change of Control
shall be deemed to have occurred for purposes of this Agreement by virtue of any
transaction which results in Executive, or a group of persons which includes
Executive, acquiring, directly or indirectly, securities representing 20 percent
or more of the voting power of outstanding securities of Merix.

8.4  DISABILITY. Termination of Executive's Employment based on "Disability"
shall mean termination without further compensation under this Agreement, due to
Executive's absence from Executive's full-time duties with Merix for 180
consecutive days as a result of Executive's incapacity due to physical or mental
illness, unless within 30 days after notice of termination by Merix following
such absence Executive shall have returned to the full-time performance of
Executive's duties.

9.   SUCCESSORS; BINDING AGREEMENT.

9.1  This Agreement shall be binding on and inure to the benefit of Merix and
its Successors and assigns. Upon Executive's written request, Merix will seek to
have any Successor by agreement, assent to the fulfillment by Merix of its
obligations under this Agreement. If such a request is made, failure of Merix to
obtain such assent prior to or at the time a company becomes a Successor shall
constitute Good Reason for termination by Executive of his or her employment
and, if a Change of Control of the Company has occurred, shall entitle Executive
to the benefits pursuant to Section 4.

9.2  This Agreement shall inure to the benefit of and be enforceable by
Executive and Executive's legal representatives, executors, administrators and
heirs.

10.  RESIGNATION OF CORPORATE OFFICES. Executive will resign Executive's office,
if any, as a director, officer or trustee of Merix, its subsidiaries or
affiliates and of any other corporation or trust of which Executive serves as
such at the request of Merix, effective as of the date of termination of
employment. Executive agrees to provide Merix such written resignation(s) upon
request and that no severance will be paid until after such resignation(s) are
provided.

11.  GOVERNING LAW, ARBITRATION. This Agreement shall be construed in accordance
with and governed by the laws of the State of Oregon. Any dispute or controversy
arising under or in connection with this Agreement or the breach thereof, shall
be settled exclusively by arbitration under the Mutual Agreement to Arbitrate
Claims signed by the Executive, and judgment upon the award rendered by the
Arbitrator may be entered in any Court having jurisdiction thereof.
Notwithstanding any provision in the Mutual Agreement to Arbitrate Claims, Merix
shall pay all arbitration fees and reasonable attorney's fees and expenses
(including at trial and on appeal) of Executive in enforcing its rights under
this Agreement in the event of a Termination of Executive's Employment within 24
months following a Change of Control.

12.  AMENDMENT. No provision of this Agreement may be modified unless such
modification is agreed to in writing signed by Executive and Merix.

13.  SEVERABILITY. If any of the provisions or terms of this Agreement shall for
any reason be held invalid or unenforceable, such invalidity or unenforceability
shall not affect any other terms of this Agreement, and this Agreement shall be
construed as if such unenforceable term had never been contained in this
Agreement.

                               INDEMNITY AGREEMENT

          This Agreement is made as of December 20, 1999, by and between Merix
Corporation, an Oregon corporation (the "Corporation"), and ANAYA VARDYA
("Indemnitee"), an officer of the Corporation.

          WHEREAS, it is essential to the Corporation to retain and attract as
directors and officers of the Corporation and its subsidiaries the most capable
persons available; and

          WHEREAS, corporate litigation subjects directors and officers to
expensive litigation risks at the same time that adequate coverage of directors'
and officers' liability insurance may be unavailable; and

          WHEREAS, the Articles of Incorporation of the Corporation require
indemnification of the officers and directors of the Corporation to the fullest
extent permitted by law. The Articles and the Oregon Business Corporation Act
(the "Act") expressly provide that the indemnification provisions set forth in
the Act are not exclusive, and thereby contemplate that contracts may be entered
into between the Corporation and members of the Board of Directors and officers
with respect to indemnification of directors and officers; and

          WHEREAS, Indemnitee does not regard the protection available under the
Corporation's Articles of Incorporation, Bylaws and insurance adequate in the
present circumstances, and may not be willing to serve as a director or officer
without adequate protection, and the Corporation desires Indemnitee to serve in
such capacity.

          NOW THEREFORE, the Corporation and Indemnitee agree as follows:

     1. AGREEMENT TO SERVE. Indemnitee agrees to serve or continue to serve as a
director and/or officer of the Corporation and/or one or more of its
subsidiaries for so long as Indemnitee is duly elected or appointed or until
such time as Indemnitee tenders a resignation in writing.

     2. DEFINITIONS. As used in this Agreement:

          (a) The term "Proceeding" shall include any threatened, pending or
completed action, suit or proceeding, whether brought in the right of the
Corporation or otherwise, whether of a civil, criminal, administrative or
investigative nature, and whether formal or informal, in which Indemnitee may be
or may have been involved as a party or otherwise, by reason of the fact that
Indemnitee is or was a director and/or officer of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise,


                                       1

<PAGE>

whether or not serving in such capacity at the time any liability or expense is
incurred for which indemnification or reimbursement can be provided under this
Agreement.

          (b) The term "Expenses" includes, without limitation thereto, expense
of investigations, judicial or administrative proceedings or appeals, amounts
paid in settlement by Indemnitee, attorneys' fees and disbursements and any
expenses of establishing a right to indemnification under Section 7 of this
Agreement, but shall not include the amount of judgments or fines against
Indemnitee.

          (c) References to "other enterprises" shall include employee benefit
plans; references to "fines" shall include any excise tax assessed with respect
to any employee benefit plan; references to "serving at the request of the
corporation" shall include any service as a director, officer, employee or agent
of the Corporation which imposes duties on, or involves services by, such
director, officer, employee or agent with respect to an employee benefit plan,
its participants, or beneficiaries; and a person who acted in good faith and in
a manner reasonably believed to be in the interest of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the Corporation" as referred to in this Agreement.

     3. INDEMNITY IN THIRD PARTY PROCEEDINGS. The Corporation shall indemnify
Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is
a party to or threatened to be made a party to any Proceeding (other than a
Proceeding by or in the right of the Corporation to procure a judgment in its
favor) against all Expenses, judgments and fines actually and reasonably
incurred by Indemnitee in connection with such Proceeding, but only if
Indemnitee acted in good faith and in a manner which Indemnitee reasonably
believed to be in or not opposed to the best interests of the Corporation and,
in the case of a criminal proceeding, in addition, had no reasonable cause to
believe that Indemnitee's conduct was unlawful. The termination of any such
Proceeding by judgment, order of court, settlement, conviction or upon a plea of
nolo contendere, or its equivalent, shall not, of itself, create a presumption
that Indemnitee did not act in good faith and in a manner which Indemnitee
reasonably believed to be in the best interest of the Corporation, and with
respect to any criminal proceeding, that such person had reasonable cause to
believe that Indemnitee's conduct was unlawful.

          Pursuant to this Agreement, the Corporation specifically will, and
hereby does, indemnify, to the fullest extent permitted by law, Indemnitee
against any and all losses, claims, damages, liabilities and expenses, joint or
several, (or actions or proceedings, whether commenced or threatened, in respect
thereof) to which Indemnitee may become subject, as a result of serving as a
director and/or officer of Merix, under the Securities Act or any other statute
or common law, including any amount paid in settlement of any litigation,
commenced or threatened, and to reimburse them for any legal or other expenses
incurred by them in


                                       2

<PAGE>

connection with investigating any claims and defending any actions, insofar as
any such losses, claims, damages, liabilities, expenses or actions arise out of
or are based upon any untrue statement or alleged untrue statement of a material
fact regarding Merix, or the omission or alleged omission to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

     4. INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE CORPORATION. The
Corporation shall indemnify Indemnitee in accordance with the provisions of this
Section 4 if Indemnitee is a party to or threatened to be made a party to any
Proceeding by or in the right of the Corporation to procure a judgment in its
favor against all Expenses actually and reasonably incurred by Indemnitee in
connection with the defense or settlement of such Proceeding, but only if
Indemnitee acted in good faith and in a manner which Indemnitee reasonably
believed to be in or not opposed to the best interests of the Corporation,
except that no indemnification for Expenses shall be made under this Section 4
in respect of any claim, issue or matter as to which such person shall have been
finally adjudged by a court to be liable for negligence or misconduct in the
performance of Indemnitee's duty to the Corporation, unless and only to the
extent that any court in which such Proceeding was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, Indemnitee is fairly and reasonably entitled to
indemnity.

     5. INDEMNIFICATION OF EXPENSES OF SUCCESSFUL PARTY. Notwithstanding any
other provisions of this Agreement, to the extent that Indemnitee has been
successful on the merits or otherwise, in defense of any Proceeding or in
defense of any claim, issue or matter therein, including the dismissal of an
action without prejudice, Indemnitee shall be indemnified against all Expenses
incurred in connection therewith.

     6. ADVANCES OF EXPENSES. The Expenses incurred by Indemnitee pursuant to
Sections 3, 4 and 8 in any Proceeding shall be paid by the Corporation in
advance at the written request of Indemnitee, if Indemnitee shall undertake to
repay such amount to the extent that it is ultimately determined by a court that
Indemnitee is not entitled to be indemnified by the Corporation and shall
furnish the Corporation a written affirmation of the Indemnitee's good faith
belief that Indemnitee is entitled to be indemnified by the Corporation under
this Agreement. Such advances shall be made without regard to Indemnitee's
ability to repay such expenses.

     7. RIGHT OF INDEMNITEE TO INDEMNIFICATION UPON APPLICATION; PROCEDURE UPON
APPLICATION. Any indemnification or advances under Sections 3, 4, 6 or 8 shall
be made no later than 45 days after receipt of the written request of
Indemnitee, unless a determination is made within such 45 day period by (a) the
Board of Directors by a majority vote of a quorum consisting of directors who
were not parties to such proceeding, or (b) independent legal


                                       3

<PAGE>

counsel in a written opinion (which counsel shall be appointed if such quorum is
not obtainable), that the Indemnitee has not met the relevant standards for
indemnification set forth in Section 3, 4 or 8 or an exclusion set forth in
Section 9 is applicable.

          The right to indemnification or advances as provided by this Agreement
shall be enforceable by Indemnitee in any court of competent jurisdiction. The
burden of proving that indemnification or advances are not appropriate shall be
on the Corporation. Neither the failure of the Corporation (including its Board
of Directors or independent legal counsel) to have made a determination prior to
the commencement of such action that indemnification or advances are proper in
the circumstances because Indemnitee has met the applicable standard of conduct
nor an actual determination by the Corporation (including its Board of Directors
or independent legal counsel) that Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption
that Indemnitee has not met the applicable standard of conduct. Indemnitee's
expenses incurred in connection with successfully establishing Indemnitee's
right to indemnification or advances, in whole or in part, in any such
Proceeding shall also be indemnified by the Corporation.

     8. ADDITIONAL INDEMNIFICATION.

          (a) Notwithstanding any limitation in Sections 3 or 4, the Corporation
shall indemnify Indemnitee in accordance with the provisions of this Section
8(a) to the fullest extent permitted by law if Indemnitee is party to or
threatened to be made a party to any Proceeding (including a Proceeding by or in
the right of the Corporation to procure a judgment in its favor) involving a
claim against Indemnitee for breach of fiduciary duty by Indemnitee against all
Expenses, judgments and fines actually and reasonably incurred by Indemnitee in
connection with such Proceeding, provided that no indemnity shall be made under
this Section 8(a) on account of Indemnitee's conduct which constitutes a breach
of Indemnitee's duty of loyalty to the Corporation or its stockholders or is an
act or omission not in good faith or which involves intentional misconduct or a
knowing violation of the law or with respect to an unlawful distribution under
ORS 60.367.

          (b) Notwithstanding any limitation in Sections 3, 4 or 8(a), the
Corporation shall indemnify Indemnitee if Indemnitee is a party to or threatened
to be made a party to any Proceeding (including a Proceeding by or in the right
of the Corporation to procure a judgment in its favor) against all Expenses,
judgments and fines actually and reasonably incurred by Indemnitee in connection
with such Proceeding to the fullest extent permitted by the Act, including the
nonexclusivity provision of ORS 60.414(1) and any successor provision and
including any amendments to the Act adopted after the date hereof that may
increase the extent to which a corporation may indemnify its officers and
directors.


                                       4

<PAGE>

          (c) The indemnification provided by this Agreement shall not be deemed
exclusive of any other rights to which Indemnitee may be entitled under the
Restated Articles of Incorporation, the Bylaws, any other agreement, any vote of
shareholders or directors, the Act, or otherwise, both as to action in
Indemnitee's official capacity or as to action in another capacity while holding
such office. The indemnification under this Agreement shall continue as to
Indemnitee even though Indemnitee may have ceased to be a director or officer
and shall inure to the benefit of the heirs and personal representatives of
Indemnitee.

     9. EXCLUSIONS. Notwithstanding any provision in this Agreement, the
Corporation shall not be obligated under this Agreement to make any
indemnification or advances in connection with any claim made against
Indemnitee:

          (a) for which payment is required to be made to or on behalf of
Indemnitee under any insurance policy, except with respect to any excess beyond
the amount of required payment under such insurance, unless payment under such
insurance policy is not made after reasonable effort by Indemnitee to obtain
payment. The Corporation shall be subrogated with respect to any other rights of
Indemnitee with respect to any payment made by the Corporation to or on behalf
of the Corporation under this Agreement;

          (b) for any transaction from which Indemnitee derived an improper
personal benefit; or

          (c) for an accounting of profits made from the purchase and sale by

Indemnitee of securities of the Corporation within the meaning of Section 16(b)
of the Securities Exchange Act of 1934 and amendments thereto or similar
provisions of any state statutory law or common law.

     10. PARTIAL INDEMNIFICATION. If Indemnitee is entitled under any provisions
of this Agreement to indemnification by the Corporation for some or a portion of
the Expenses, judgments and fines actually and reasonably incurred by Indemnitee
in the investigation, defense, appeal or settlement of any Proceeding but not,
however, for the total amount thereof, the Corporation shall nevertheless
indemnify Indemnitee for the portion of such Expenses, judgments or fines to
which Indemnitee is entitled.

     11. BUSINESS TRANSACTIONS. The Corporation agrees that it will not effect
any Business Transaction (as defined in Article XI of the Restated Articles of
Incorporation of the Corporation) which has not been approved by the Continuing
Directors (as defined in Article XI of the Restated Articles of Incorporation of
the Corporation) of the Corporation unless the other party to the transaction
agrees in writing to (a) use its best efforts to maintain for the subsequent two
year period any and all directors' and officers' liability insurance in effect
prior to any discussions or announcement relating to such Business Transaction
and (b) assume all obligations of the Corporation under this Agreement and
indemnify Indemnitee and advance litigation expenses in accordance with this
Agreement.


                                       5

<PAGE>

     12. SEVERABILITY. If this Agreement or any portion thereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify Indemnitee as to Expenses, judgments
and fines with respect to any Proceeding to the full extent permitted by any
applicable portion of this Agreement that shall not have been invalidated or by
any other applicable law.

     13. NOTICE. Indemnitee shall, as a condition precedent to Indemnitee's
right to be indemnified under this Agreement, give to the Corporation notice in
writing as soon as practicable of any claim made against Indemnitee for which
indemnity will or could be sought under this Agreement. Notice to the
Corporation shall be directed to Merix Corporation, 1521 Poplar Lane, Forest
Grove, Oregon 97116, Attention: Secretary (or such other address as the
Corporation shall designate in writing to Indemnitee). Notice shall be deemed
received three days after the date postmarked if sent by prepaid mail, properly
addressed. In addition, Indemnitee shall give the Corporation such information
and cooperation as it may reasonably require and as shall be within Indemnitee's
power.

     14. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall constitute the original.

     15. APPLICABLE LAW. This Agreement shall be governed by and construed in
accordance with Oregon law.

     16. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Corporation and its successors and assigns.

          IN WITNESS WHEREOF, the parties hereby have caused this Agreement to
be duly executed and signed as of the day and year first above written.
