1.   OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
     ---------------------------------------------------------
     Hadco Corporation (the "Company" or "Hadco") was incorporated in
     Massachusetts in 1966. Principal products and services of the Company
     include:

     PRINTED CIRCUITS:

     Printed circuits are the basic platform used to interconnect
     microprocessors, integrated circuits and other components essential to the
     functioning of electronic systems. The Company provides customers with
     printed circuit designs and fabricates the printed circuit for the
     customer. The design and fabricated printed circuits are sold either
     separately or as a complete package. The majority of printed circuits
     fabricated by the Company are based on designs provided by the customer.

     VALUE ADDED MANUFACTURING:

     Value Added Manufacturing (VAM) primarily consists of backplane and system
     assemblies. Backplane assemblies are generally larger and thicker printed
     circuits on which connectors are mounted to receive and interconnect
     printed circuits, integrated circuits and other electronic components.
     System assemblies include the backplane, power supply, fan card, cabling
     and system chassis.

     The consolidated condensed financial statements reflect the application of
     certain accounting policies as described in this note and elsewhere in the
     accompanying notes to the consolidated condensed financial statements, as
     well as the Company's Annual Report on Form 10-K for the fiscal year ended
     October 30, 1999. These financial statements should be read in conjunction
     with the financial statements and related disclosures included in the
     above-referenced SEC filings.

     INTERIM FINANCIAL STATEMENTS
     ----------------------------
     The accompanying consolidated condensed balance sheet as of January 29,
     2000, and the consolidated condensed statements of operations for the three
     months ended January 29, 2000 and January 30, 1999 and the consolidated
     condensed statements of cash flows for the three month periods ended
     January 29, 2000 and January 30, 1999 are unaudited, but in the opinion of
     management, include all adjustments (consisting only of normal, recurring
     adjustments) necessary for a fair presentation of results for these interim
     periods. Results of operations for the interim periods are not necessarily
     indicative of results to be expected for the entire year or any future
     period.

     ended January 29, 2000 and January 30, 1999 do not include 595,130 and
     698,224 common equivalent shares, respectively, as their effect would be
     anti-dilutive.

</TABLE>


     Based on the amount outstanding on the Company's credit facility as of
     January 29, 2000, the Company has approximately $113.75 million of
     borrowings available.

4.   BUSINESS SEGMENTS AND GEOGRAPHIC AREAS
     --------------------------------------
     During the fourth quarter of fiscal 1999, the Company adopted Statement of
     Financial Accounting Standards ("SFAS") NO. 131, Disclosure about Segments
     of an Enterprise and Related Information. The Company's businesses are
     internally reported as two segments. These segments, which are based on
     differences in products, technologies, and services, are Printed Circuits
     and Value Added Manufacturing (VAM). Hadco evaluates performance of these
     segments based on profit or loss from operations, not including
     non-recurring charges.

     Transactions between segments are recorded at fair market value. Costs of
     centralized sales, marketing and administration are allocated to the
     segments receiving benefits of the centralized functions. Unallocated
     general corporate expenses include the elimination of inter-segment
     profits, the costs of executive management for the Company, plus the
     amortization of acquired intangibles and goodwill relating to acquisitions.
     Management does not represent that these segments, if operated separately,
     would report the operating income and other financial information shown.

     Basis of presentation. The Company sold on May 18, 1998, $200 million
     aggregate principal amount of 9 1/2% Senior Subordinated Notes due in 2008
     (the "Notes"). The Notes are fully and unconditionally guaranteed on a
     senior subordinated basis, jointly and severally, by certain of the
     Company's wholly-owned domestic subsidiaries (the "Guarantors"). The
     Guarantors are Hadco Santa Clara, Inc., Hadco Phoenix, Inc., CCIR of Texas
     Corp., and CCIR of California Corp. The consolidating condensed financial
     statements of the Guarantors are presented below and should be read in
     connection with the Consolidated Condensed Financial Statements of the
     Company. Separate financial statements of the Guarantors are not presented
     because (i) the Guarantors are wholly-owned and have fully and
     unconditionally guaranteed the Notes on a joint and several basis and (ii)
     the Company's management has determined such separate financial statements
     are not material to investors and believes the consolidating condensed
     financial statements presented are more meaningful in understanding the
     financial position of the Guarantors.

     There are no significant restrictions on the ability of the Guarantors to
     make distributions to the Company.

RESULTS OF OPERATIONS - FIRST QUARTER
-------------------------------------
Net sales for the first quarter of fiscal 2000 increased 3.7%, or $8.8 million,
over net sales for the same period in fiscal 1999. Printed circuit net sales
increased 11.1%, or $21.1 million, in the first quarter of fiscal 2000 from the
comparable period in fiscal 1999 due to higher unit shipments and a shift in mix
towards higher priced printed circuits with more layers and greater densities.
This increase was partially offset by a 2.6 percentage point decline in average
pricing for printed circuits. VAM net sales decreased 27.3%, or $12.3 million,
in the first quarter of fiscal 2000 from $45.3 million in the comparable period
in fiscal 1999. VAM net sales decreased due to reduced production of low margin
assembly products.

The gross profit margin increased to 16.7% of net sales for the quarter ended
January 29, 2000 from 13.7% in the comparable quarter in fiscal 1999. Better
capacity utilization of printed circuit operations caused gross margins to
increase 5.6 percentage points, and the production of higher-margin assembly
products in the VAM segment increased gross margins by 0.5 percentage point.
These increases in gross margin were offset by lower pricing on printed
circuits, which decreased gross margins by 2.2 percentage points, and by lower
capacity utilization of VAM operations, which caused gross margins to decrease
by 0.9 percentage point. The changes in the VAM segment were a result of
management's decision to cease production of low margin assembly products.

Operating expenses increased by $2.8 million for the first quarter of fiscal
2000 over the first quarter of fiscal 1999. Operating expenses as a percent of
net sales increased to 8.5% in the first quarter of fiscal 2000 versus 7.6% in
the comparable period of fiscal 1999. The increase is due to an increase of $1.8
million in selling expenses from expanded sales coverage, an increase of $0.8
million in general and administrative expenses and slightly higher research and
development expenses. The Company includes in operating expenses charges for
actual expenditures and accruals, based on estimates, for environmental matters.
To the extent and in amounts Hadco believes circumstances warrant, it will
continue to accrue and charge to operating expenses cost estimates relating to
known environmental matters.

Interest and other income increased slightly for the quarter ended January 29,
2000 as compared to the comparable quarter in the prior fiscal year due to
higher average cash balances available for investing. Interest expense decreased
in the first quarter of fiscal 2000 as compared to the first quarter of fiscal
1999 due to lower average outstanding debt balances during the first quarter of
fiscal 2000 as compared to the first quarter of fiscal 1999.

INCOME TAXES
------------
The Company provides for income taxes on an interim basis using its anticipated
effective annual income tax rate. The Company anticipates an effective annual
income tax rate for fiscal 2000 of 38%, which is slightly less than the combined
federal and state statutory rates. The anticipated effective rate was increased
by amortization of goodwill (which is not tax deductible), offset by the benefit
of the Company's foreign sales corporation, research and development tax credits
and various state investment tax credits. The effective tax rate for fiscal 2000
is based on current tax laws.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------
Net cash used in operating activities for the first quarter of fiscal 2000 was
$11.9 million, as compared to net cash provided by operations in the first
quarter of fiscal 1999 of $17.8 million, a difference of $29.7 million. This
decrease resulted primarily from a reduction of $35.7 million in accounts
payable and accrued expenses. This decrease was offset by an increase of $6.1
million in earnings before non-cash items in the first quarter of fiscal 2000
versus the first quarter of fiscal 1999. The decrease in accounts payable and
accrued expenses is a result of higher incentive compensation accrued in fiscal
1999 and paid during the first quarter of fiscal 2000; in addition, the Company
incurred a significant amount of capital expenditures during the fourth quarter
of fiscal 1999, which were paid during the first quarter of fiscal 2000.

Net cash used in investing activities in the first quarter of fiscal 2000 was
$8.8 million, a decrease of $7.9 million from the first quarter of fiscal 1999,
due to lower capital expenditures.

Net cash provided by financing activities was $12.5 million in the first quarter
of fiscal 2000 as compared to $1.3 million in the comparable period in the prior
year. The increase was primarily due to borrowings on the Company's credit
facility to fund operating activities during the first quarter of fiscal 2000,
as described above.

At January 29, 2000, the Company had working capital of $86.8 million and a
current ratio of 1.69, as compared to working capital of $47.8 million and a
current ratio of 1.30 at October 30, 1999. The increase in working capital
resulted primarily from an increase in accounts receivable, as customer order
and shipment rates increased late in the quarter, combined with the reductions
in accounts payable noted above.

The Company believes its current borrowing capacity, coupled with the funds
generated from the Company's operations will be sufficient to fund its
anticipated working capital, capital expenditure and debt payment requirements
through fiscal year 2000. Because the Company's capital requirements cannot be
predicted with certainty, however, there is no assurance that the Company will
not require additional financing during this period. There is no assurance that
any additional financing will be available on terms satisfactory to the Company
or not disadvantageous to the Company's security holders, including the holders
of the Notes.

The Company believes the ultimate disposition of known environmental matters
will not have a material adverse effect upon the liquidity, capital resources,
business or consolidated financial position of the Company. However, one or more
of such environmental matters could have a significant negative impact on the
Company's consolidated financial results for a particular reporting period.

YEAR 2000 READINESS DISCLOSURE STATEMENT
----------------------------------------
As part of the Year 2000 project, the Company completed an internal assessment
of its operations to determine the extent to which the Company could be
adversely affected by Year 2000 issues. This internal assessment included both
Information Technology (IT) systems and non-IT systems.

The critical software systems used by the Company to run its business include
MFG/PRO, PeopleSoft, Oracle, and Corsair. The Company conducted testing of its
various IT systems, running programs with dates including and after the Year
2000. During these tests the Company did not experience problems processing data
or effecting transactions.

                                       16

YEAR 2000 READINESS DISCLOSURE STATEMENT (CONTINUED)
----------------------------------------------------
The Company's internal assessment of its manufacturing equipment for Year 2000
compliance was done on a plant-by-plant basis and was completed in May 1999.
Thereafter, software upgrades were installed in certain manufacturing systems.
The Company tested the new software and did not encounter date-related
processing issues. There can be no assurance, however, that the Company's
testing of its various IT systems and manufacturing equipment and software was
sufficient to discover all Year 2000 issues. Year 2000 issues not discovered by
the Company could have a material adverse effect on the Company's business,
results of operations and financial condition.

In fiscal 1999, the Company developed business continuity/contingency plans for
all its facilities. Such plans cover Year 2000 issues and potential disruptions.
There can be no assurance that the implementation of business
continuity/contingency plans developed by the Company will result in alleviation
or remediation of any business interruption or disruption that the Company may
experience.

As part of the Year 2000 project, the Company surveyed all of its active
suppliers to determine their Year 2000 compliance status. The Company worked
with its key suppliers to obtain more detailed information about their
compliance status, and performed on-site assessment of certain critical
suppliers. The Company also completed contingency plans for addressing potential
supply disruptions. There can be no assurance that the Company will not
experience disruption in its supply chain, or that its contingency plans will
alleviate or remedy any disruption experienced.

The Company has not to date encountered any date-related processing issues or
any business interruption in connection with the Year 2000 roll-over to January
1, 2000. The Company did, however, experience a greater than seasonal reduction
of customer orders due to Year 2000 concerns, particularly in the computer
server market, during the first two months of its first fiscal quarter, November
and December 1999. Customer order rates in January 2000 were 33% higher than in
the November/December 1999 period, across all end markets of the Company's
customer base.

To date, approximately 30,500 hours of employee time have been devoted to Year
2000 issues and approximately $5.9 million has been expended in systems upgrades
directly relating to Year 2000. The source of these funds has been the working
capital of the Company.

A software or system Year 2000 compliance failure, with respect to the Company's
internal systems, software and equipment or that of third party service
providers, major customers or suppliers, could prevent the Company from
fulfilling customer orders. Any such failure, if not quickly remedied, would
have a material adverse effect on the Company's business, results of operations,
and financial condition. The lost revenues that would result from the Company's
inability to operate even one of its major volume manufacturing plants for any
significant period of time would have a material adverse effect on the Company.

The Company could face an even greater risk of significant damages if the
Company were to be found responsible for the shutdown of one of its customers'
facilities. This could occur if the Company was unable to supply parts integral
to the end products manufactured by the Company's customers. In such
circumstances, the legal liability of the Company could have a material adverse
effect on the Company's business, results of operations, and financial
condition.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

DERIVATIVE FINANCIAL INSTRUMENTS, OTHER FINANCIAL INSTRUMENTS, AND DERIVATIVE
COMMODITY INSTRUMENTS

SFAS No. 107 requires disclosure about fair value of financial instruments.
Financial instruments consist of cash equivalents, accounts receivable, accounts
payable and long-term debt obligations. The fair value of these financial
instruments approximates their carrying amount, except for the 9 1/2% Senior
Subordinated Notes (the "Notes"), at January 29, 2000. The fair market value of
the Notes was $191 million with a carrying amount of $199.4 million at January
29, 2000. Although the fair market value of the Notes is less than the carrying
amount, settlement at the reported fair value is not possible due to
cost-prohibitive redemption premiums.

PRIMARY MARKET RISK EXPOSURES

The Company's primary market risk exposures are in the areas of interest rate
risk and foreign currency exchange rate risk. The Company incurs interest
expense on loans made under the Company's credit facility at interest rates
which are fixed for a maximum of six months. At January 29, 2000, the Company's
outstanding borrowings under the credit facility were $85.0 million, at a
weighted average interest rate of 6.75%. This interest rate is a combination of
two Eurodollar loans, one for $50.0 million maturing February 25, 2000 and one
for $20.0 million maturing February 18, 2000, both at a rate of 6.625%. The
balance was comprised of a $10.0 million overnight swing-line loan at 6.75% and
a $5.0 million overnight base rate loan at 8.5%. The Company has the option to
fix the interest rates on the Eurodollar rate loans for periods of one, two,
three or six months. The Eurodollar Rate is subject to market risks and will
fluctuate.

Substantially all of the Company's business outside the United States is
conducted in U.S. dollar denominated transactions. The Company does operate a
volume manufacturing facility in Malaysia. Some of the expenses of this facility
are denominated in Malaysian ringgits. Expenses denominated in ringgits include
local salaries and wages, utilities and some operating supplies. The Company
also funds a small sales offices in Ireland and Great Britain, where expenses
are paid in British Pounds, Irish Punts and Eurodollars. However, the Company
believes that these operating expenses will not have a material adverse effect
on the Company's business, results of operations or financial condition.
