INDEPENDENT ACCOUNTANT'S REPORT

To the Board of Directors
SEMX Corporation

We have reviewed the accompanying consolidated balance sheet of SEMX Corporation
and Subsidiaries as of September 30, 2000, and the related consolidated
statements of income for the three-month period and the nine-month period then
ended, and cash flows for the nine-month period then ended. These financial
statements are the responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the consolidated financial statements taken
as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying consolidated financial statements for them to be in
conformity with generally accepted accounting principles.

NOTE 3.  ACQUISITIONS AND DISPOSITIONS

Acquisitions:

On April 10, 2000, the Company's Polese Company subsidiary acquired the assets
of Advanced Packaging Concepts ("APC"), a Vista, CA based manufacturer of
ceramic packages for the wireless markets, in a business combination accounted
for as a purchase. Polese Company acquired the assets and assumed selected
liabilities of APC for $1,300 in cash, which was financed in part by a $1,000
interim term loan that was repaid during the second quarter of 2000. In
addition, Polese Company paid approximately $120 in costs associated with the
acquisition of APC. The fair value of assets acquired, including approximately
$695 allocated to goodwill, amounted to approximately $1,300 and liabilities
assumed amounted to $1,000. In a companion transaction, associated intellectual
property rights were acquired for approximately 95 shares of restricted SEMX
common stock, valued at $1,000. The transaction provides the sellers of APC a
royalty of 2 1/2 % against future sales to certain existing customers for a
period of 3 years. At closing, the Company advanced a total of $150 to the
sellers against this royalty. The Company vacated the Vista premises as of July
31, 2000 and has completed the integration of APC's operations into Polese
Company's existing facilities as of October, 2000.

On May 1, 2000, the Company's Polese subsidiary purchased the technology and
assets of Engelhard Corporation's ("Engelhard") electroless gold plating
business in Anaheim, CA for total cash consideration of $317. In addition, a
finders fee consisting of Non Qualified Stock options to purchase 40 shares of
SEMX Common, valued at $426 was recorded. The fair value of assets acquired,
including $426 allocated to goodwill, amounted to $743. Electroless gold plated
deposits satisfy manufacturing requirements for wire bonding, die-attachment and
corrosion resistance, but eliminate many of the design restrictions brought
about by conventional electrolytic gold plating. Polese Company vacated the
Anaheim premises as of July 31, 2000 and has completed the integration of the
electroless gold plating operations into Polese Company's existing facilities as
of October 2000.

Dispositions:

In February 1999, the Company sold its connector businesses, Retconn
Incorporated ("Retconn") and ST Electronics, Inc. ("ST") to Litton Corporation
("Litton"). Litton acquired the specified assets and assumed certain liabilities
of Retconn and ST, as defined in the purchase agreement, in consideration for a
cash payment to the Company of $23,871. The liabilities assumed by Litton
amounted to approximately $3,500. The purchase price was subject to adjustment
for changes in Retconn's closing date balance sheet and in December, 1999 the
Company paid Litton $320 in settlement of the final purchase price adjustment.
In addition, the Company is prevented from directly competing in the connector
business for a period of three years. The Company recorded a pretax gain of
$8,430 on the transaction.

NOTE 5.  REDEEMABLE PREFERRED STOCK

On June 1, 2000, the Company received $10,000 in gross proceeds from Series B
Redeemable Preferred Stock from a group led by ACI Capital Co ("ACI"). Attached
to the instrument were warrants to purchase 1 million shares of SEMX Common
Stock with an exercise price initially valued at $10.00 per share, subject to a
reset provision dependent on the underlying market price of SEMX Common Stock,
with a floor of $7.00 per share. On the accompanying Balance Sheet, a value of
$250 was assigned to the warrants and an initial value of $9,750 was assigned to
the redeemable preferred stock. The $250 value assigned to the warrants was
credited to additional paid in capital and will be accreted to the value of the
Series B Preferred Stock over the five year term. The Company paid approximately
$900 in investment banking, financing, legal and accounting fees in conjunction
with the offering. A total of $800 of the fees associated with the offering were
accounted for as a reduction in the carrying value of the preferred stock on the
accompanying balance sheet and will be accreted to the value of the Series B
Preferred Stock over the five year term. The remaining $100 costs were allocated
to expenses of issuing the warrants and were charged to paid in capital. Of this
total approximately $300 was paid to a firm affiliated with John Moorhead, who
is a member of the SEMX Board of Directors for services rendered in assistance
with the financing. Additionally, warrants to purchase an aggregate 60 shares of
SEMX common stock at an exercise price of $7.00 per share were issued to an
investment banking firm; a firm associated with John Moorhead; and certain other
individuals. The Series B Preferred Stock is subject to mandatory redemption in
5 years for $10,000 and cash dividends are payable semiannually at a rate of 6%,
and in preference to any dividends on the Company's Common Stock, and are
subject to successive rate increases in the event of uncured late dividend
payments or other events of default. The Liquidation Preference of the Series B
Preferred Stock is equal to the stated value plus accrued and unpaid dividends
to the date of liquidation. The Series B Preferred Stock granted ACI the right
to add two directors to the SEMX Board of Directors.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS - Third quarter and first nine months 2000 compared to
third quarter and first nine months 1999

REVENUE:

Total revenue for the third quarter, 2000 of $19,102,000 increased $2,744,000 or
17% as compared to the third quarter 1999. Total revenue for the first nine
months of 2000 of $53,176,000, increased $5,877,000 or 12% as compared to the
similar 1999 period. First nine months 1999 included sales of $2,122,000 from
the Company's connector business, ("Retconn") through the February 1999
disposition date. Excluding Retconn sales, total revenue for the first nine
months 2000 increased $ 7,999,000 or 18% compared to the similar 1999 period.

The Company's Materials Group's third quarter 2000 sales of $13,916,000
increased $1,728,000, or 14%, from the third quarter 1999, primarily due to
increased sales of gold wire at SPM. SPM's third quarter 2000 sales increased by
$1,124,000 or 34% as compared to the comparable 1999 period. Polese Company's
third quarter 2000 sales increased by $604,000 or 7% as compared to the prior
year period reflecting improved sales of microprocessor lids, cellular base
station heat dissipation products and the introduction of new products in the
first quarter 2000. The first nine months 2000 sales of the Materials Group,
excluding Retconn increased by $5,818,000 or 18% over the similar prior year
period. Polese's nine months sales of $25,589,000 have increased $2,585,000 or
11% from 1999 levels, due to improved sales of microprocessor lids, cellular
base station heat dissipation products and the introduction of new products in
the first quarter 2000, offset by the disruptions in the second quarter. The
increase in SPM's first nine months 2000 sales to $13,000,000 from $9,767,000 in
the prior year period, was primarily due to increased shipments of gold wire as
well as increased sales from the overseas locations.

The Company's Services Group third quarter 2000 revenues increased $1,016,000 or
24% as compared to the third quarter 1999 reflecting strong performance at the
Group's Singapore operation, ISP. First nine months 2000 sales increased by
$2,181,000 or 18% over the comparable period of 1999. The Services Group revenue
increase for both the quarter and nine month period, was the result of an
increase in the demand for reclaimed wafers, primarily at ISP, with improvements
also taking place at the Group's ASP U.S. and European operations.

The Company does a significant amount of international business, both from its
domestic locations, as well as through overseas manufacturing locations. Direct
sales of the Company's products into foreign markets, as a percentage of
consolidated revenue ("foreign sales percentage") during the first nine months
of 2000 was 27%, as compared to 25% for the prior year period. This compares to
foreign sales percentages of 22% for the third quarter 2000 and 19% for the
third quarter 1999. The Company has foreign manufacturing operations in the
Netherlands ("ASP B.V."), in Morocco, Semiconductor Materials S.A.R.L.
("S.A.R.L."), in Malaysia, SPM(M) SDN.BHD ("SPM(M)") and in Singapore, ISP.
During the third quarter 2000, the Company derived revenue from ASP B.V. of
$705,000, from S.A.R.L. of $224,000, from SPM(M) of $204,000, and from ISP of
$1,459,000. During the first nine months of 2000, the Company derived revenue
from ASP B.V. of $2,394,000, from S.A.R.L. of $637,000, from SPM(M) of $684,000,
and from ISP of $3,609,000. Foreign sales made through the Company's domestic
operations are made through foreign manufacturer's representatives and are
priced and paid for in U.S. dollars. Sales for ASP B.V., S.A.R.L., SPM(M) and
ISP are conducted in the local currencies of Dutch Guilders, Dirhams, Ringits
and Singapore Dollars, respectively, and constitute a foreign sales percentage
of 14% in third quarter and 14% in the first nine months of 2000.

The Company's consolidated backlog as of September 30, 2000 was approximately
$26,839,000 compared to backlog of approximately $19,459,000 at September 30,
1999 and $17,184,000 at December 31, 1999. The increase in consolidated backlog
during 2000 was led by Polese's increase from approximately $8,117,000 at
December 31, 1999 to approximately $17,270,000 at September 30, 2000. Backlog at
ASP has improved significantly from approximately $5,628,000 since at the
beginning of year to approximately $7,458,000 at September 30, 2000. The backlog
for SPM has decreased approximately $1,330,000 from beginning of year levels, to
$2,111,000 at September 30, 2000. Approximately 28% of the consolidated backlog
at September 30, 2000 includes orders that are not expected to be shipped within
one year. The Company expects the consolidated backlog to remain strong for the
remainder of 2000.

GROSS PROFIT:

Gross profit of $4,910,000 for the third quarter 2000 decreased $932,000, or
16%, from the third quarter 1999. Excluding Retconn, first nine months 2000
gross profit increased by $581,000 or 4% from the comparable 1999 period. The
Materials Group's third quarter 2000 gross profit of $3,617,000 decreased
$1,324,000 or 27% compared to the third quarter 1999. The Materials Group's
gross profit decrease reflects disruptions at Polese Company due to the
integration of the APC and Englehard businesses, as well as less than expected
yields due to transitions involved with shifting production towards assembled
thermal management products. As a result of the above, the Materials Group's
gross margin decreased from 41% in last years third quarter to 26% in the third
quarter 2000. The Service Group's third quarter 2000 gross profit of $1,293,000
increased $392,000 or 44% as compared to the comparable periods in

                                       12
<PAGE>

1999 primarily due to increased sales. The Services Group's third quarter 2000
gross margin of 25% increased from the third quarter 1999 gross margin of 22%
primarily due to improved performance at ISP.

SELLING, GENERAL AND ADMINISTRATIVE:

Selling, general and administrative ("SG&A") expenses in the third quarter 2000
increased $394,000, or 11% from the comparable 1999 period. The increase in SG&A
during the third quarter 2000 was primarily due to increased sales. SG&A
expenses as a percentage of revenue decreased slightly from 22% in the third
quarter 1999 to 21% for the third quarter 2000. Excluding Retconn, SG&A expense
for the first nine months of 2000 increased $1,424,000 or 14% over the first
nine months of 1999, reflecting an 18% increase in sales for the first nine
months of 2000 over comparable prior year period.

GAIN ON SALE OF CONNECTOR BUSINESS

Income before Provision for Income Taxes and Minority Interest for the first
nine months of 1999 include a gross gain on the sale of the Company's Connector
Business on February 19, 1999 of $8,430,000.

INTEREST EXPENSE (NET):

Net interest expense for the third quarter 2000 decreased $70,000 from the third
quarter 1999. Net interest expense for the first nine months of 2000 decreased
$405,000 from the similar period last year. The decrease in net interest expense
is due to reduced debt levels from February 19, 1999 forward due to the
principal repayments from proceeds from the sale of the Connector business and
lower borrowing rates.

PROVISION FOR INCOME TAXES:

A provision of $186,000 for income taxes has been recorded at an effective rate
of 32% for the third quarter of 2000 as compared to a provision of $695,000 at
an effective rate of 38% for the third quarter of 1999. A provision of
$1,057,000 at an effective rate of 35% for income taxes has been recorded for
the first nine months of 2000 as compared a provision of $5,908,000 at an
effective rate of 48% for the first nine months of 1999. The lower effective
rates utilized in the 2000 periods reflect state investment credits and Federal
R&D tax credits. The provision for the first nine months of 1999 includes taxes
of $4,527,000 associated with the gain on the sale of the Connector business.

MINORITY INTEREST:

The Company has a 50.1% interest in the Services Group's Singapore based ISP
operation. In accordance with generally accepted accounting principles the
Company fully consolidates the operating results of ISP and then, excludes 49.9%
of ISP's net income or loss from its consolidated net income, reflecting the
minority owner's share in ISP's results. In the first nine months and the third
quarter of 2000, the Company has excluded from net income, $195,000 and $75,000
respectively, reflecting the minority owners share of ISP's income, net of tax.
In the first nine months and third quarter of 1999, the Company's net income
excludes losses of $24,000 and $30,000 respectively, associated with ISP, net of
tax.

NET INCOME:

As a result of the above, net income of $314,000 for the third quarter 2000
decreased by $852,000 from the third quarter 1999. Excluding an after tax gain
on the sale of the Connector business of $3,903,000 in the first nine months of
1999, net income from continuing operations increased by $641,000 for the first
nine months of 2000 as compared to the similar 1999 period.

NET INCOME AVAILABLE TO COMMON SHAREHOLDERS

Net income available to common shareholders is the numerator in the Company's
calculation of Basic and Diluted Income per common share and reflects dividends
payable to Preferred Stockholders and accretion of the carrying value of the
Series B Preferred Stock issued on June 1, 2000. The Company accrues
approximately $67,000 per month representing dividends payable and accretion
related to the Series B Preferred Stock.

LIQUIDITY AND CAPITAL RESOURCES

General

To support the Company's growth the Company has historically made significant
capital expenditures to support its facilities and manufacturing processes as
well as working capital needs. The Company has financed its capital needs
through cash flow from operations, issuance of Preferred Stock, line of credit
facilities, term loans from banks, other bank financing including gold
consignment supply agreements, and capital leases.

Summary of 2000 Activity

At September 30, 2000, the Company had cash and cash equivalents of $455,000 and
had an available balance on its revolving credit facility of $6,363,000 as
compared to $1,774,000 and $500,000 respectively at September 30, 1999.

Net cash provided by operating activities in the first nine months of 2000
amounted to $1,546,000 as compared to $4,511,000 in the first nine months of
1999. Cash provided by operations decreased compared to the first nine months of
1999 principally as a result of first nine months operating income and working
capital changes.

Cash used by investing activities amounted to $9,327,000 in the first nine
months of 2000. The Company completed the acquisition of the assets of APC on
April 1, 2000 and Englehard on May 1, 2000. On February 19, 1999 the Company
completed the sale of its Connector business and realized cash proceeds of
$22,191,000. During the nine months ended September 30, 2000 and 1999, the
Company invested $7,009,000 and $1,732,000, respectively, in property and
equipment. This investment excludes $1,151,000 in the 2000 period and $900,000
in the 1999 period for equipment acquired under capital leases.

Net Cash provided by financing activities amounted to $7,852,000 in the first
nine months of 2000 as compared to cash used of $23,710,000 during the 1999
period. On June 1, 2000 the Company realized net proceeds of approximately
$9,100,000 from the issuance of Series B Preferred Stock. During the first nine
months of 2000 the Company repaid $2,003,000 under a term loan and bridge loan
facilities and borrowed $967,000 under its Bank revolving line of credit. In
addition, the Company made payments of $1,907,000 under capital lease
obligations. On September 30, the Company paid a semi-annual cash dividend to
the holders of Series B Preferred in the amount of $201,000.

Factors Affecting Future Liquidity

On June 1, 2000, the Company received $10,000,000 in gross proceeds from the
issuance of Series B Redeemable Preferred Stock to a group led by ACI . Attached
to the instrument were warrants to purchase 1 million shares of SEMX Common
Stock with an exercise price initially valued at $10.00 per share, subject to a
reset provision dependent on the underlying market price of SEMX Common Stock,
with a floor of $7.00 per share. The Company paid approximately $900,000 in
investment banking, financing, legal and accounting fees in conjunction with the
offering. Of this total approximately $300,000 was paid to a firm affiliated
with John Moorhead, who is a member of the SEMX Board of Directors for services
rendered in assistance with the financing. Additionally, warrants to purchase an
aggregate 60,000 shares of SEMX common stock at an exercise price of $7.00 per
share were issued to an investment banking firm; a firm associated with John
Moorhead; and certain other individuals. The Series B Preferred Stock is subject
to mandatory redemption in 5 years and cash dividends are payable semiannually
at a rate of 6%, subject to successive rate increases in the event of uncured
late payments or events of default. The Series B Preferred Stock granted ACI the
right to add two directors to the SEMX Board of Directors.

On November 1, 1999 the Company entered into a Revolving Credit, Term Loan and
Security Agreement with PNC Bank. The Credit Facility replaced the existing
revolving credit and interim term loan facilities which the Company had with
First Union and Fleet. The Credit Facility, which has a three year term,
consists of a formula based $8,500,000 revolving credit facility and a
$6,234,000 term loan which are secured by substantially all of the Company's
domestic assets. Revolving credit facility availability of up to S$4,000,000
Singapore dollars (approximately $2,300,000 US) is reserved for issuance of a
standby letter of credit in support of the Company's continuing guarantee of
ISP's debt. The interest rate on revolving credit borrowings are, at the
Company's option, based on either the prime rate or a floating Eurodollar rate
plus a margin of 2.75%. At the Company's option, the term loan interest rate is
based on either prime plus 0.5% or a floating Eurodollar rate plus a margin of
3.0%. Principal payments under the $6,234,000 term loan are due in equal monthly
installments of $74,214 over the three-year term. Full payment of any
outstanding debt on the term loan is due on October 31, 2002.

In August 2000 the Company's 50.1% owned ISP subsidiary refinanced its existing
debt and entered into a credit facility with Keppel Tatlee Bank. The facility
provides for a total of S$11,950,000 (approximately $6,900,000 US) in term and
overdraft borrowings secured by ISP's property and equipment and partially
guaranteed by the Company. In conjunction with the refinancing the Company was
able to reduce its guarantee of ISP's debt from S$5,000,000 Singapore dollars
(approximately $2,900,000 US) to S$4,000,000 (approximately $2,300,000 US). The
reduced guarantee is secured by a standby letter of credit of up to S$4,000,000

                                       14

<PAGE>

Singapore dollars issued by PNC Bank in favor of ISP's lenders. In the event of
default, as defined by ISP's lending agreements, Keppel Tatlee Bank could draw
down the S$4,000,000 standby letter of credit provided by the Company's Bank.

In December 1996, the Company entered into a consignment agreement (the "Gold
Consignment Agreement") with Fleet Precious Metals ("FPM") which, as amended
expires June 30, 2002. Under the Gold Consignment Agreement, the Company
purchases gold used in its manufacturing of materials. The Gold Consignment
Agreement provides for gold on consignment not to exceed the lesser of 6,500
troy ounces of gold or gold having a market value of $2,400,000. The Gold
Consignment Agreement requires the Company to pay a consignment fee of 4.5% per
annum based upon the value of all gold consigned to the Company.

In conjunction with the Company's acquisition of Polese Company on May 27, 1993,
the Company acquired from Frank J. Polese, the former sole shareholder of Polese
Company, all of the rights, including a subsequently issued patent, for certain
powdered metal technology and its application to the electronics industry. For a
period of ten years from May 1993, Mr. Polese has the right to receive 10% of
(i) the pre-tax profit from the copper tungsten product line, after allocating
operating costs and (ii) the proceeds of the sale, if any, by the Company of the
powdered metal technology. During the first nine months of 2000, the Company
charged against operations a total of $169,000 under this agreement.

The Company continually seeks to broaden its product lines by various means,
including through acquisitions. The Company intends to pursue only those
acquisitions for which it will be able to arrange the necessary financing by
means of the issuance of additional equity, the use of its cash or, through bank
or other debt financing.

PART II.  OTHER INFORMATION

Item 1. Legal Proceedings

An investigation by the Securities and Exchange Commission ("SEC) into certain
sales of the Company's common stock during 1996 is continuing. As a general
matter, the SEC takes the position that its investigation should not be
construed as an indication that any violations of law have occurred or as an
adverse reflection upon any person or security. The Company and any corporate
personnel involved have cooperated fully with the SEC in its investigations.
