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

  CRITICAL ACCOUNTING POLICIES AND ESTIMATES

     Management's Discussion and Analysis of Financial Condition and Results of
Operations discusses our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires our
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the disclosure of contingent assets and liabilities
at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. On an on-going basis our management
evaluates its estimates and judgements. Our management bases its estimates and
judgements on historical experience and on various other factors that are
believed to be reasonable under the circumstances, the results of which form the
basis for making judgements about the carrying values of assets and liabilities
that are not readily apparent from other sources. Actual results may differ from
these estimates under different assumptions or conditions.

     Our management believes the following critical accounting policies, among
others, affect our more significant judgements and estimates used in the
preparation of our consolidated financial statements:

          Accounts Receivable.  We perform ongoing credit evaluations of our
     customers and we adjust credit limits based upon each customer's payment
     history and current credit worthiness, as determined by credit information
     available at that time. We continuously monitor collections and payments
     from our customers and we maintain allowances for doubtful accounts for
     estimated losses resulting from the inability of our customers to make
     required payments. While such losses have historically been within our
     expectations and the provisions established, if the condition of our
     customers were to deteriorate, resulting in an impairment of their ability
     to make payments, additional allowances may be required.

          Inventories.  We write down our inventory for estimated obsolescence
     or unmarketable inventory equal to the difference between the cost of the
     inventory and the estimated market value based upon assumptions about
     future demand and market conditions. If actual future demand or market
     conditions are less favorable than those historically experienced or
     projected by us, additional inventory write-downs may be required.

          Valuation of Goodwill and other Intangible Assets.  We assess the
     impairment of goodwill and other identifiable intangible assets whenever
     events or changes in circumstances indicate that the carrying value may not
     be recoverable. Factors we consider important which could trigger an
     impairment review include, but are not limited to, the following:

             significant underperformance relative to historical or projected
        future operating results;

             significant changes in the manner of our use of the acquired assets
        or the strategy for our overall business;

             significant negative industry or economic trends; significant
        decline in our stock price for a sustained period; and

             our market capitalization relative to net book value.

             When we determine that the carrying value of goodwill and other
        intangible assets may not be recoverable based upon the existence of one
        or more of the above indicators of impairment, we measure any impairment
        bases on a projected discounted cash flow method using a discount rate
        determined by us to be commensurate with the risk inherent in our
        current business model. During the year ended December 31, 2001 we
        recorded an impairment charge totaling $133.3 million, of which, $129.1
        related to goodwill.

             In 2002, Statement of Financial Accounting Standards ("SFAS") No.
        142, "Goodwill and Other Intangible Assets" became effective and as a
        result, we will cease to amortize goodwill, resulting in a decrease to
        annual amortization expense of approximately $16.6 million. In lieu of
        amortization, we are required to perform an initial impairment review of
        our goodwill in 2002 and an annual impairment review thereafter. We
        currently do not expect to record an impairment charge upon completion
        of the initial impairment review. However, there can be no assurance
        that at the time the review is completed a material impairment charge
        will not be recorded.

                                        1
<PAGE>

          Income Taxes.  We record a valuation allowance to reduce our deferred
     tax assets to the amount that we believe is more likely than not to be
     realized. While we have considered future taxable income and ongoing
     prudent, feasible tax planning strategies in assessing the need for the
     valuation allowance, in the event we were to determine that we would not be
     able to realize all or part of our net deferred tax assets in the future,
     an adjustment to the net deferred tax assets would be charged to income in
     the period such determination was made. Likewise, should we determine that
     we would be able to realize our deferred tax assets in the future in excess
     of its net recorded amount, an adjustment to the net deferred tax asset
     would increase income in the period such determination was made.

  YEAR ENDED DECEMBER 31, 2000 COMPARED TO YEAR ENDED DECEMBER 31, 2001

     Net sales for the year ended December 31, 2001 were $1,206.5 million,
representing a $398.5 million, or 24.8%, decrease from the same period in 2000.
The decrease was primarily a result of continued weakness in printed circuit
board sales to key North American telecommunication and networking customers,
partially offset by the impact of acquisitions made in 2000 and 2001.

     Cost of goods sold for the year ended December 31, 2001 was $993.6 million,
or 82.4% of sales (excluding one-time write-offs of $49.3 million of inventory
related to the Restructuring), compared to $1,230.6 million, or 76.7% of sales,
for the year ended December 31, 2000. Cost of goods sold as a percent of net
sales increased as a result of a higher percentage of EMS sales in 2001, which
generally have lower margins than printed circuit board sales, and lower
absorption of our fixed overhead cost in our facilities throughout North
America, Europe and Asia due to lower demand from our key telecommunication and
networking customers.

     Selling, general and administrative expenses for the year ended December
31, 2001 were $96.8 million, a decrease of $24.4 million, or 20.1%, versus the
comparable period in 2000 (excluding the non-cash compensation expense charge of
$104.4 million in March 2000). These costs decreased primarily due to cost
reductions related to the Restructuring and a reduction in expenses as a result
of the transfer of the operations formerly conducted by Forward, ISL,
Zincocelere and the PCB production facility of Ericsson Telecom AB in March
2000, partially offset by increases in general and administrative expenses
related to the acquisitions completed in 2000 and 2001.

     In connection with Group's initial public offering in March 2000, Group
amended the terms of the performance stock options held by members of management
to eliminate the exercisability restrictions and variable exercise price terms.
The amended performance options have a fixed exercise price of $9.00 per share
and are immediately exercisable. As a result of these amendments, we recorded a
one-time, non-cash compensation expense charge of approximately $33.6 million
during the three months ended March 31, 2000.

     Also in connection with Group's initial public offering in March 2000,
Group converted each 6 2/3 shares of class A common stock and class A series II
common stock into one share of common stock. This conversion eliminated the
variable terms of the class A common stock and class A series II common stock
and resulted in a one-time, non-cash compensation expense charge of
approximately $63.0 million recorded during the three months ended March 31,
2000. This charge reflects the difference between the cost of the class A common
stock and the class A series II common stock and the value of the common stock
into which it was convertible at March 23, 2000.

     Additionally, in connection with Group's initial public offering in March
2000, Viasystems terminated the monitoring and oversight agreement and financial
advisory agreement with HMTF. As consideration for such termination, Group
granted to HMTF options to purchase an aggregate of 2,134,000 shares of Group's
common stock at an exercise price of $21.00 per share. The option grant resulted
in a net one-time, non-cash compensation expense charge of approximately $7.8
million recorded during the three months ended March 31, 2000.

     During the quarter ended December 31, 2001, we recorded non-cash asset
impairments totaling $141.1 million primarily related to the write-off of
long-lived assets in accordance with Statement of Financial Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of" ("FAS 121"). Based on current business enterprise values using
common appraisal methods, the assessment identified impairments of long-lived
assets acquired pursuant to the Top Line, Laughlin-Wilt and NC&S acquisitions.
The calculated business enterprise values determined were compared to the net
book values of the related long-lived assets with the excess of net book value
over the business enterprise value representing the amount of the impairment
loss. The impairment loss for each group of assets, totaling $133.3 million, was
first charged against goodwill ($129.1 million) with the remaining amounts being
charged

                                        2
<PAGE>

to property, plant and equipment ($4.2 million). The impairment resulted from
the economic downturn experienced during 2001, primarily related to our
telecommunication and networking customers. Through the third fiscal quarter of
2001, it was expected that the economic downturn impacting these assets was a
short-term inventory correction. However, in the fourth quarter it became clear
to management that the downturn impacting these assets was more severe and of a
long-term nature resulting in a significant decline in profitability that is not
expected to return in the near term.

     During the year ended December 31, 2001, we recorded a series of
restructuring charges totaling $59.8 million. These charges were taken in light
of the economic downturn primarily related to our large telecommunication and
networking customers. During 2001 we began evaluating our cost position compared
to anticipated levels of business for 2001 and beyond and determined that plant
shutdowns, plant consolidations and downsizing were required to reduce costs to
more appropriate levels in line with current and expected customer demand. A
summary of the 2001 restructuring activity (the "Restructuring") by quarter is
as follows:

     During the quarter ended March 31, 2001, we recorded a restructuring charge
of $12.0 million, primarily related to the phase one workforce reductions in our
Richmond, Virginia PCB fabrication facility as well as small workforce
reductions at certain other North American operations. The workforce reductions
impacted a total of 2,507 employees, of which 1,915 were regular, union
employees, 547 were regular, non-union employees and 45 were temporary/contract
employees. All of these employees were terminated by December 31, 2001.

     During the quarter ended June 30, 2001, we recorded a restructuring charge
of $30.5 million, primarily related to the closure of our Richmond, Virginia and
San German, Puerto Rico PCB fabrication facilities as well as small workforce
reductions at certain other North American and European operations. The facility
closures and workforce reductions impacted a total of 1,613 employees, of which
1,228 were regular, union employees, 373 were regular, non-union employees and
12 were temporary/contract employees. All of these employees were terminated by
December 31, 2001.

     During the quarter ended September 30, 2001, we recorded a restructuring
charge of $16.2 million, primarily related to the consolidation of our two San
Jose, California PCB assembly operations as well as headcount reductions at our
corporate offices. The consolidation and workforce reductions impacted a total
of 471 employees, of which 150 were regular, union employees, 315 were regular,
non-union employees and 6 were temporary/contract employees. All of these
employees were terminated by December 31, 2001.

     During the quarter ended December 31, 2001, we recorded a restructuring
charge of $7.1 million, primarily related to workforce reductions at our
European PCB fabrication facility as well as small workforce reductions at other
European facilities. The workforce reductions impacted a total of 455 employees,
all of which were regular, non-union employees. All of these employees were
terminated by December 31, 2001.

     Additionally, during the quarter ended December 31, 2001, we reversed $6.0
million of restructuring charges previously recorded. This reversal primarily
related to a change in our plan related to the consolidation of our two San
Jose, California PCB assembly operations. Initially, the plan included
consolidating the leased operation into the owned operation, resulting in a
restructuring charge related to the contractual obligation on the leased
facility. Subsequently, we amended our plan and made the decision to consolidate
the owned operation into the leased operation resulting in a reversal to the
restructuring charge related to the lease commitment.

     In connection with the Restructuring, we also recorded impairment charges
totaling $82.7 million to write-down to fair value certain land and buildings as
well as machinery and equipment, office equipment and systems that were obsolete
or redundant due to the closure and consolidation of facilities pursuant to the
Restructuring. Included in the impairment charge were the following amounts: a
write-down of land, buildings and leasehold improvements totaling $25.4 million,
related to our Richmond, Virginia and San German, Puerto Rico PCB fabrication
facilities that were closed; a write-down of machinery and equipment totaling
$14.9 million, a write-down of office equipment totaling $37.7 million, and a
write-down of systems and construction in progress totaling $4.7 million, each
primarily related to obsolete or redundant assets at our Richmond, Virginia and
San German, Puerto Rico PCB fabrication facilities that were closed as well as
certain other North American and European operations that were consolidated.

     At December 31, 2001, $17.7 million of the assets held for disposal had
been sold or otherwise disposed, leaving $16.3 million remaining on the books,
of which $13.0 million consisted of the land and building related to our
Richmond, Virginia PCB fabrication facility. We are actively marketing the land
and building for sale
                                        3
<PAGE>

and expect to complete the disposal of the assets during 2002. The remaining
$3.3 million of net book value of assets held for disposal on the books at
December 31, 2001 consists primarily of machinery and equipment and office
equipment related to redundant or obsolete assets at our Richmond, Virginia and
San German, Puerto Rico PCB fabrication facilities and are expected to be
disposed of during the next 18-24 months.

     The significant components of the restructuring charge recorded for lease
and other contractual commitments totaling approximately $13.0 million, are as
follows: $8.5 million for leased and other facility commitments; $3.2 million
for lease commitments on machinery and equipment; $1.2 million for waste water
project commitments; and $0.1 million for other commitments.

     Also in connection with the Restructuring, we wrote-off inventory resulting
in a $49.3 million and $0.8 million charge to cost of goods sold during the
quarters ended June 30, 2001 and September 30, 2001, respectively. During the
quarter ended December 31, 2001, we reversed inventory write-offs previously
taken totaling $0.8 million. With respect to the inventory written-off during
the quarter ended June 30, 2001, we have disposed of $39.1 million of the
inventory and reversed the write-off and sold $1.0 million of the inventory,
resulting in a remaining balance of $9.1 million at December 31, 2001. We expect
to dispose of the remaining obsolete inventory during fiscal year 2002.

     The restructuring and impairment charges were determined based on formal
plans approved by our management using the best information available to it at
the time. The amounts we may ultimately incur may change as the balance of the
plans are executed.

     We continue to review our operations in light of the continued economic
downturn related to our telecommunication and networking customers. These
reviews could result in additional workforce reductions. The impact these
activities could have on our results of operations is not currently known.

     European PCB Group has disposed of the operations formerly conducted by
Forward Group Plc and the PCB production facility of Ericsson Telecom AB. In
addition, an administrative receiver has been appointed in respect of European
PCB Group's ISL business. As a result, the business formerly conducted by
Zincocelere S.p.A. is the only material asset remaining within European PCB
Group. Accordingly, we compared the carrying amount of all current amounts due
from European PCB Group, including the PCB Group Notes, to their undiscounted
expected future cash flows. We have concluded that amounts due from European PCB
Group have been impaired. As a result, we recorded a charge for the quarter
ended September 30, 2001 totaling $144.1 million to reflect the write-off of
such amounts. This charge consisted of $127.6 million related to the PCB Group
Notes and $16.5 million related to trade receivables.

     Depreciation and amortization decreased $18.6 million, from $144.9 million
for the year ended December 31, 2000, to $126.3 million for the same period of
2001, primarily due to a reduction in expenses as a result of the distribution
of the operations formerly conducted by Forward ISL, Zincocelere and the PCB
production facility of Ericsson Telecom AB in March 2000 and due to a reduced
fixed asset base as a result of the impairment of property and equipment held
for disposal related to the closure of our Richmond, Virginia

                                        4

and San German, Puerto Rico PCB facilities, partially offset by the impact to
depreciation of acquired fixed assets and to amortization of acquired
intangibles from the acquisitions completed in 2000 and 2001.

     Other expense decreased $9.6 million, from $111.7 million for the year
ended December 31, 2000, to $102.1 million for the same period of 2001,
primarily due to reduced interest expense and amortization of deferred financing
costs related to the recapitalization in connection with Group's initial public
offering completed in March 2000 and reductions in market benchmark interest
rates realized during 2001, partially offset by higher interest margins charged
on borrowed funds under our senior secured credit facility resulting from
amendments to the credit agreement completed during 2001.

     During the quarter ended March 31, 2000, we recorded, as an extraordinary
item, a one-time, non-cash write-off of deferred financing fees of approximately
$31.2 million, net of $0 income tax benefit, related to deferred financing fees
incurred on debt under our prior credit agreement, which was retired before
maturity with proceeds from Group's initial public offering.

  YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 2000

     Net sales for the year ended December 31, 2000 were $1.6 billion,
representing a $311.6 million, or 24.1%, increase from the comparable period in
1999. The increase was primarily due to volume growth in the telecom/datacom
industry and acquisitions completed in 1999 and 2000, partially offset by the
reduction in sales associated with the distribution of the operations formerly
conducted by Forward, ISL, Zincocelere and Viasystems Sweden in March 2000.

     Cost of goods sold for the year ended December 31, 2000 was $1.2 billion,
or 76.7% of net sales, compared to $969.6 million, or 75.0% of net sales, for
the year ended December 31, 1999. Cost of goods sold as a percent of net sales
increased year over year as a result of a higher percentage of EMS sales in
2000, which generally have lower margins than printed circuit board sales. This
was partially offset by higher production volume absorption and cost containment
initiatives.

     Selling, general and administrative expenses (excluding the non-cash
compensation expense charge of $110.1 million and $104.4 million in 1999 and
2000, respectively) for the year ended December 31, 2000 decreased by $1.3
million versus the comparable period in 1999. These costs decreased primarily
due to a reduction in expenses as a result of the distribution of the operations
formerly conducted by Forward, ISL, Zincocelere and Viasystems Sweden in March
2000, partially offset by increases in general and administrative expenses
related to the acquisitions completed in 1999 and 2000.

     During the year ended December 31, 1999 we recorded a non-cash compensation
charge of $110.1 million, which reflects the difference between the cost of the
class A common stock and class A series II common stock and the value of common
stock into which it was convertible at December 31, 1999.

     In connection with Group's initial public offering in March 2000, we
amended the terms of the performance stock options held by members of management
to eliminate the exercisability restrictions and variable exercise price terms.
The amended performance options have a fixed exercise price of $9.00 per share
and are immediately exercisable. As a result of these amendments, we recorded a
one-time non-cash compensation expense charge of approximately $33.6 million
during the year ended December 31, 2000.

     Also in connection with Group's initial public offering in March 2000,
Group converted each 6 2/3 shares of class A common stock and class A series II
common stock into one share of common stock. This conversion eliminated the
variable terms of the class A and class A series II common stock and resulted in
a one-time non-cash compensation expense charge of approximately $63.0 million
recorded during the year ended December 31, 2000.

     Additionally, in connection with Group's initial public offering in March
2000, Viasystems terminated the monitoring and oversight agreement and financial
advisory agreement with HMTF. As consideration for such termination, we granted
HMTF options to purchase an aggregate of 2,134,000 shares of Group's common
stock at an exercise price of $21.00 per share. The option grant resulted in a
net one-time non-cash compensation expense charge of approximately $7.8 million
recorded during the year ended December 31, 2000.

     Other expense decreased $36.3 million, from $148.0 million for the year
ended December 31, 1999, to $111.7 million in the same period of 2000, due
primarily to reduced interest expense and amortization of deferred financing
costs related to the recapitalization in connection with the initial public
offering completed

                                        5
<PAGE>

in March 2000. Additionally, in 1999 we recorded a loss on disposal of plant,
property and equipment related to the closure of our Selkirk, Scotland facility.

     Depreciation and amortization decreased $37.2 million, from $182.1 million
for the year ended December 31, 1999, to $144.9 million for the same period in
2000, primarily as a result of the distribution of the operations formerly
conducted by Forward, ISL, Zincocelere and Viasystems Sweden in March 2000. This
decrease was partially offset by the depreciation of acquired fixed assets and
amortization of acquired intangibles from the acquisitions completed in 1999 and
2000.

     During 1999, we recorded a non-cash impairment loss of $468.4 million
related to the write-off of long-lived assets in accordance with Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of." Based on current
business enterprise values using common appraisal methods, the assessment
identified impairment of long-lived assets acquired pursuant to the Forward, ISL
and Zincocelere acquisitions. The calculated business enterprise values
determined were compared to the net book value of the related long-lived assets
with the difference representing the amount of the impairment loss. The
impairment loss for each group of assets was first charged against goodwill with
any remaining amounts being charged to the other acquired intangibles and
property, plant and equipment, if necessary. The impairment resulted from
significant changes in the markets served by the acquired businesses that were
not anticipated at the time of each acquisition, most significantly a decline in
market pricing. The decline in market pricing was due to the convergence of two
factors: significant currency fluctuations and the emergence of significant
offshore competition from Asia Pacific. While the primary currency for the
acquired businesses is the U.K. pound sterling, their competitors were in
Continental Europe and beginning to emerge from Asia Pacific. The currencies for
most of the Continental European and Asia Pacific countries declined
significantly against the U.K. pound sterling, which resulted in an improved
relative cost position for the competitors and reduced market pricing. This
decline in market pricing has resulted in a significant decline in profitability
that is not expected to return in the near term.

     During 1999, we recorded a one-time non-cash write-off of $17.6 million
related to in-process research and development acquired in the Kalex
acquisition.

     During 1999, we recorded a one-time non-cash cumulative effect of a change
in accounting principle of $18.4 million (net of $6.7 million income tax
benefit) related to the write-off of the net book value of start-up costs as of
January 1, 1999.

     During the year ended 2000, we recorded, as an extraordinary item, a
one-time, non-cash write-off of deferred financing fees of approximately $31.2
million (net of $0 income tax benefit) related to deferred financing fees
incurred on debt under the old credit agreement, which was retired before
maturity with proceeds from Group's initial public offering.

  HOLDING COMPANY STRUCTURE

     Group is a holding company that has no significant assets other than the
capital stock of Viasystems and therefore, Group relies on dividends and
distributions from Viasystems as its sole source of cash. Group's right to
participate in dividends or other distributions from Viasystems is subject to
restrictions imposed by the terms of Viasystems' senior secured credit facility,
senior unsecured notes and senior subordinated notes, as well as the prior
rights of Viasystems' creditors and other statutory restrictions.

  CASH FLOWS

     Net cash provided by operating activities was $47.9 million for the year
ended December 31, 2001, compared to net cash provided by operating activities
of $31.2 million for the same period in 2000. The increase in net cash provided
by operating activities relates to collection of receipts from certain major
customers and reduced investments in inventories, partially offset by payments
to vendors.

     Net cash used in investing activities was $89.4 million for the year ended
December 31, 2001, compared to $497.2 million for the year ended December 31,
2000. The net cash used in investing activities for 2001 included $78.8 million
related to capital expenditures with the remainder used for two small
acquisitions. In 2000, net cash used in investing activities included $360.3
million related to the acquisitions of the Wire Harness Business of
International Wire, Marconi Communications Inc.'s network component and services
business ("NC&S"), Top Line Electronics Corporation, Lucent Technologies' global
provisioning facility in Rouen, Laughlin-Wilt and Accutec, with the remaining
amounts related to capital expenditures.

                                        6
<PAGE>

     Net cash provided by financing activities was $31.1 million for the year
ended December 31, 2001, compared to $490.0 million for the year ended December
31, 2000. The net cash provided by financing activities for 2001 relates
principally to the $100.0 million in proceeds realized from the July 2001
issuance of Viasystems senior unsecured notes and warrants to purchase Group's
common stock, less payments on revolving loans under Viasystems' senior credit
facility and repayment of other long-term and capital lease obligations. Cash
provided by financing activities in 2000 relates principally to the proceeds
from our March 2000 initial public offering, as offset by debt repayments.

     On July 19, 2001, we issued $100.0 million principal amount of senior
unsecured notes and warrants to purchase 10 million shares of Group's common
stock to affiliates of Hicks, Muse, Tate & Furst Incorporated for a purchase
price of $100.0 million. The senior unsecured notes bear interest at 14% per
annum and mature on May 1, 2007. Interest is not payable currently, but rather
will accrete semi-annually and be payable in full at maturity of the senior
unsecured notes. The warrants are immediately exercisable and have an exercise
price of $.01 per share and terminate in 2011. We have allocated $30.0 million
of the proceeds from the senior unsecured notes to paid-in-capital and $70.0
million to debt, which represents the relative fair value of the securities at
the time of issuance. The resulting debt discount of $30.0 million is being
amortized, using the effective interest method, over the life of the senior
unsecured notes. At December 31, 2001, the remaining unamortized discount was
$26.9 million. The fair value of the warrants was determined using a
Black-Scholes pricing model, assuming expected volatility of 116%, a risk-free
rate of return of 3.0% and a dividend yield of 0%.

     The following summarizes our contractual obligations at December 31, 2001,
and the effect such obligations are expected to have on our liquidity and cash

(1) Includes capital lease obligations.

     In addition to the above contractual cash obligations, we guaranteed
approximately 12 million British Pounds (approximately $18.0 million) of an
obligation with the Department of Trade and Industry (the "DTI") of the United
Kingdom in respect of a grant provided to ISL. The grant is also secured by land
and a building in North Tyneside owned by ISL which has an appraised value in
excess of the grant obligation. Throughout the year, we have been engaged in
discussions with the DTI regarding the guarantee and the grant. On January 31,
2002, we and European PCB Group entered into a settlement agreement with the
DTI. Under the settlement agreement, we and European PCB Group jointly and
severally agreed to pay 12.0 million British Pounds (approximately $18.0
million) in 9 installments beginning January 31, 2002 and ending on December 31,
2003. The first installment totaled 2.0 million British Pounds (approximately
$3.0 million) and was paid on January 31, 2002 by European PCB Group with the
remaining installments due periodically through December 31, 2003. We believe
that European PCB Group has the ability and will continue to make the scheduled
payments due under the settlement agreement. Furthermore, we believe that
proceeds from the sale of the land and building in North Tyneside will be
sufficient to satisfy all or substantially all amounts paid pursuant to the
settlement agreement. European PCB Group has agreed to indemnify us in the event
we are required to make any such payments.

     In addition, we have $9.8 million of letters of credit issued with respect
to certain indebtedness of Zincocelere. The remaining obligation due by
Zincocelere under the indebtedness totals approximately 7.2 million Euros
(approximately $6.3 million). Historically, Zincocelere has made the scheduled
payments under the indebtedness and we believe Zincocelere will continue to
operate and make all future payments required under the indebtedness.

     As a result of the dramatic downturn in telecom component demand during
2001 and our highly leveraged capital structure, we expect to fail to satisfy
certain financial maintenance covenants contained in
                                        7
<PAGE>

our senior secured credit facility on March 31, 2002. In anticipation of this
circumstance, we entered into an amendment to our credit agreement on March 29,
2002. The amendment provides that our credit facility lenders will refrain from
exercising any rights or remedies in respect of our failure to comply prior to
May 29, 2002. Under the terms of the amendment, our revolving borrowings under
the senior secured credit facility are limited to $100 million, unless our
consolidated net sales for the preceding eight week period exceed specified
thresholds, in which case our revolving loan availability is increased to $150
million. The amendment further increases the interest rates payable on these
borrowings by .25% per annum, imposes additional financial and operating
restrictions and provides for the grant of certain additional liens to secure
these borrowings. A fee of approximately $1.5 million was paid to our credit
facility lenders in connection with the amendment.

     In light of these developments, we have retained Rothschild Inc. to assist
us in evaluating several recapitalization alternatives in an effort to reduce
debt and strengthen our balance sheet.

     As of December 31, 2001, we had $34.2 million of cash and cash equivalents
and our working capital was $122.1 million. Giving effect to the recent
amendment to our credit agreement, as of December 31, 2001, we would have had
revolver availability under the senior secured credit facility of $78.9 million.

     We anticipate that our primary uses of cash for the next twelve months will
be:

     - to meet working capital requirements;

     - for capital expenditures for maintenance, replacement and acquisitions of
       equipment, expansion of capacity, productivity improvements and product
       and process technology development; and

     - to pay interest on, and to repay principal of, indebtedness under our
       senior secured credit facility, our senior subordinated notes and our
       other outstanding indebtedness.

     We expect that our primary sources of cash will be cash on hand, cash from
operating activities and revolving borrowings under our senior secured credit
facility, as amended. We anticipate that these sources of cash will be
sufficient to meet our requirements for working capital, capital expenditures,
and debt service over the next 12 months. These expectations, however, assume
that the forbearance under the recent amendment to our credit agreement will be
extended in order to permit us to implement a restructuring or other plan. In
the event that we are unable to enter into satisfactory arrangements with the
lenders under our senior secured credit facility to extend such forbearance
beyond May 29, 2002, up to $1 billion of indebtedness could become due and
payable shortly thereafter. This indebtedness consists of term loans of $437.8
million and revolving loans of $10.6 million under the senior secured credit
facility, $79.5 million (net of $26.6 million of unamortized discount) of senior
unsecured notes, and $500 million principal amount of senior subordinated notes.
Although there is no current default under the senior unsecured notes or the
senior subordinated notes, a default would arise under these debt obligations in
the event of an acceleration of the maturity of the senior secured credit
facility indebtedness. In such event, we would not have sufficient liquidity to
repay such indebtedness and we would not expect to be able to refinance such
indebtedness. In addition, our future operating performance and ability to meet
our financial obligations will be subject to future economic conditions and to
financial, business and other factors, many of which will be beyond our control.

     Borrowings under our senior secured credit facility bear interest at
floating rates which vary according to the interest option we select. Base rate
term loans bear interest at the then effective base rate plus an applicable
margin ranging from 2.50% to 3.00%. Eurocurrency term loans bear interest at the
then effective eurocurrency base rate plus an applicable margin ranging from
3.50% to 4.00%. Revolving credit loans bear interest, at our option, at the then
effective base rate plus 2.5% or the then effective eurocurrency base rate plus
3.50%. Our senior subordinated notes bear interest, payable semiannually, at the
rate of 9 3/4% per annum.

  RECENT EVENTS

     As of March 27, 2002, HMTF has increased its investment in Viasystems
through open market purchases of $232.1 million of Viasystems' 9 3/4 senior
subordinated notes and $51.3 million of Viasystems' senior secured bank debt.
These purchases were made at a discount to the face amount.

  NET OPERATING LOSS CARRYFORWARD

     For United States federal income tax purposes we had net operating loss
carryforwards, or NOLs, amounting to approximately $867.1 million as of December
31, 2001. These NOLs have been reduced by approximately $92.5 million to reflect
the offset against the NOLs of cancellation of indebtedness income we

                                        8
<PAGE>

recognized as a result of open market purchases at a discount during 2001 by
HMTF of Viasystems, indebtedness with an aggregate principal amount of $163.4
million.

     These NOLs expire in 2018 through 2021 if not utilized before then to
offset taxable income. Section 382 of the Internal Revenue Code of 1986, as
amended, and regulations issued thereunder impose limitations on the ability of
corporations to use NOLs if the corporation experiences more than a 50% change
in ownership during certain periods. We believe an ownership change occurred in
March 2000 in connection with our initial public offering. As a consequence, the
utilization of our NOLs is limited pursuant to Section 382 to approximately
$96.5 million per year, with any unused portion carried over to succeeding
years. Further changes in ownership in future periods could substantially
restrict our ability to utilize our tax net operating loss carryforwards. In
addition, as of December 31, 2001, we had NOLs of $17.7 million in the United
Kingdom, $29.1 million in the Netherlands, $6.5 million in Italy, $54.4 million
in Luxembourg, $0.5 million in Brazil, $17.0 million in Canada, $0.5 million in
Puerto Rico and $28.6 million in Hong Kong. These NOLs carry forward
indefinitely except Canada and Puerto Rico, which expire in 2008.

  RECENT ACCOUNTING PRONOUNCEMENTS

     In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statements of Financial Accounting Standards No. 141 ("SFAS 141"), "Business
Combinations", and No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets".

     SFAS 141 supercedes Accounting Principles Board Opinion No. 16, "Business
Combinations". The most significant changes made by SFAS 141 are: (1) requiring
that the purchase method of accounting be used for all business combinations
initiated after June 30, 2001, (2) establishing specific criteria for the
recognition of intangible assets separately from goodwill, and (3) requiring
unallocated negative goodwill to be written off immediately as an extraordinary
gain (instead of being deferred and amortized). We are currently assessing the
impact of SFAS 141 on our operating results and financial condition.

     SFAS 142 supercedes Accounting Principles Board Opinion No. 17, "Intangible
Assets". SFAS 142 primarily addresses the accounting for goodwill and intangible
assets subsequent to their acquisition (i.e., the post-acquisition accounting).
The provisions of SFAS 142 will be effective for fiscal years beginning after
December 15, 2001. The most significant changes made by SFAS 142 are: (1)
goodwill and indefinite lived intangible assets will no longer be amortized, (2)
goodwill will be tested for impairment at least annually at the reporting unit
level, (3) intangible assets deemed to have an indefinite life will be tested
for impairment at least annually, and (4) the amortization period of intangible
assets with finite lives will no longer be limited to forty years. Upon
implementation of SFAS 142, our amortization expense for fiscal year 2002 is
expected to decrease by approximately $16.6 million compared to fiscal year 2001
as a result of no longer amortizing goodwill. We currently do not expect to
record an impairment charge upon completion of the initial impairment review.
However, there can be no assurance that at the time the review is completed a
material impairment charge will not be recorded.

     In August 2001, the FASB issued Statement of Financial Accounting Standards
No. 144 ("SFAS 144"), "Accounting for the Impairment or Disposal of Long-lived
Assets". SFAS 144 supercedes Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-lived Assets and Assets to be
Disposed of" and the accounting and reporting provisions of Accounting
Principles Board Opinion No. 30, "Reporting the Results of
Operations -- Reporting the Effects of Disposal of a Segment of a Business, and
Extraordinary, Unusual and Infrequently Occurring Events and Transactions." SFAS
144 also amends Accounting Research Bulletin No. 51, "Consolidated Financial
Statements," to eliminate the exception to consolidation for a subsidiary for
which control is likely to be temporary. The provision of SFAS 144 will be
effective for fiscal years beginning after December 15, 2001. The most
significant changes made by SFAS 144 are: (1) removes goodwill from its scope
and, therefore, eliminates the requirements of SFAS 121 to allocate goodwill to
long-lived assets to be tested for impairment, and (2) describes a
probability-weighted cash flow estimation approach to deal with situations in
which alternative course of action to recover the carrying amount of a
long-lived assets are under consideration or a range is estimated for the amount
of possible future cash flows. We currently do not expect the implementation of
SFAS 144 to have a material impact on our operating results and financial
condition. However, there can be no assurance that at the time the review is
completed a material impairment charge will not be recorded.

  IN-PROCESS RESEARCH AND DEVELOPMENT

     Kalex's in-process R&D value was comprised of three primary projects
consisting of developing Rambus technology, increasing board layer count and
developing ball grid array substrates capability. At the acquisition date, R&D
programs ranged from 65% to 80% complete and total continuing R&D commitments to
complete the projects were expected to be $2.4 million. Since the date of the
acquisition we have completed the Rambus project and continued to pursue the
board layer count project and the ball grid array substrate project.

     Rambus technology is designed to improve the communication between current
and next generation fast central processing unit microchips and peripherals on
the motherboard. This requires motherboards with finer lines, much lower
impedance, and extremely small variance in specification tolerance. The
applications for Rambus technology are personal computers, workstations,
mainframes, mobile phones, communications equipment and network systems.

     Because we have capabilities at most of our facilities to produce high
layer count printed circuit boards, the board layer count project has progressed
quickly and is nearing completion. The ball grid array substrates project is
designed to improve printed circuit board density and performance. This project,
to be successful, will require specific machinery and precision tools, including
unique drilling, routing, lamination, and etching equipment. We will further
evaluate this program before committing to such investment.

     These estimates are subject to change, given the uncertainties of the
development process, and no assurance can be given that deviations from these
estimates will not occur.

  CONVERSION TO THE EURO

     On January 1, 1999, eleven participating countries of the European Union
converted to the Euro as their common national currency. The previous national
currencies of these countries will still be accepted as legal tender until at
least January 1, 2002. Upon conversion to the Euro we did not experience any
disruption or material impact on our results of operations, financial condition
or cash flows.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  INTEREST RATE RISK

     At December 31, 2000 and 2001, approximately $488.6 and $448.4 million,
respectively, of our long-term debt, specifically borrowings outstanding under
our senior credit facility and the loan notes, bore interest at variable rates.
Accordingly, our earnings and cash flow are affected by changes in interest
rates. Assuming the current level of borrowings at variable rates and assuming a
two percentage point increase in the average interest rate under these
borrowings, it is estimated that our interest expense for the year ended
December 31, 2000 and 2001, would have increased by approximately $9.8 and $9.0
million, respectively. In the event of an adverse change in interest rates,
management would likely take actions that would mitigate our exposure to
interest rate risk; however, due to the uncertainty of the actions that would be
taken and their possible effects, this analysis assumes no such action. Further,
this analysis does not consider the effects of the change in the level of
overall economic activity that could exist in such an environment.

  FOREIGN CURRENCY RISK

     We conduct our business in various regions of the world, and export and
import products to and from several countries. Our operations may, therefore, be
subject to volatility because of currency fluctuations. Sales and expenses are
frequently denominated in local currencies, and results of operations may be
affected adversely as currency fluctuations affect our product prices and
operating costs or those of our competitors. From time to time, we enter into
foreign exchange forward contracts to minimize the short-term impact of foreign
currency fluctuations. We do not engage in hedging transactions for speculative
investment reasons. Our hedging operations historically have not been material
and gains or losses from these operations have not been material to our cash
flows, financial position or results from operations. There can be no assurance
that our hedging operations will eliminate or substantially reduce risks
associated with fluctuating currencies.
