                                     PART I

ITEM 1.  BUSINESS

GENERAL

     Hadco is the largest manufacturer of advanced electronic interconnect
products in North America. The Company offers a wide array of sophisticated
manufacturing, engineering and systems integration services to meet its
customers' electronic interconnect needs.

     The Company's principal products are multilayer rigid printed circuits and
backplane and systems assemblies. Printed circuits are the basic platforms used
to interconnect microprocessors, integrated circuits and other components
essential to the functioning of electronic systems. 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. Systems assemblies include the backplane, power supply,
fan card, cabling and system chassis.

     Hadco's advanced manufacturing and assembly facilities are designed to meet
the accelerated time-to-market and time-to-volume requirements of its customers
whose markets are characterized by high growth rates, rapid technological
advances and short product life cycles. Through the office of the Chief
Technology Officer (CTO), the Company coordinates the activities of the
development groups at each production facility. The CTO and production site
development groups work closely with customers during the early stages of the
product life-cycle in an effort to develop process changes and refinements
required for volume production. The development projects include increased
printed circuit density, embedded passive components, advanced materials, laser
direct imaging, fine pitch assembly and new product offerings.

                                        1
<PAGE>   3

     Hadco acquired Zycon on January 10, 1997. This acquisition increased
Hadco's net sales significantly, added approximately 600,000 square feet of
manufacturing space (approximately a 100% increase at the time) and
substantially expanded the Company's manufacturing capabilities and geographic
reach. These acquired manufacturing capabilities include state-of-the-art West
Coast facilities for volume production of complex printed circuits and backplane
and system assemblies, a quick-turn prototype and design facility on the East
Coast, and a volume production facility in Malaysia.

     Hadco acquired Continental Circuits on March 20, 1998. This acquisition
also increased Hadco's net sales significantly, added approximately 305,000
square feet of manufacturing space, and further expanded the Company's
manufacturing capabilities and geographic reach. These acquired manufacturing
capabilities include a facility in Phoenix, Arizona for the volume production of
complex printed circuits, a quick-turn prototype facility in Austin, Texas, a
flexible printed circuit facility in California, and printed circuit engineering
and design sites in Texas, California, and Colorado. On April 30, 1999, the
Company sold substantially all of the assets of its flexible printed circuit
facility (Dynaflex division) for approximately $2.7 million. Dynaflex's assets,
liabilities and operations were not significant to the Company. Accordingly, pro
forma information has not been presented.

     The Acquisitions have broadened the Company's customer base, expanded its
involvement in various industry sectors, added new proprietary technologies and
increased its sales force.

     The Company was incorporated in Massachusetts in 1966.  The Company's
principal executive offices are located at 12A Manor Parkway, Salem, New
Hampshire 03079; its telephone number is (603) 898-8000, and its internet site
is http://www.hadco.com.

PRODUCTS AND SERVICES

     The Company's products and services are designed to meet its customers'
interconnect needs for dense multilayer printed circuits and backplane and
system assemblies. See Note 14 of Notes to Consolidated Financial Statements for
financial segment information concerning printed circuits and backplane and
system assemblies. Hadco offers complementary processes and capabilities that
span the product life cycle. The Company's offering includes the following
products and services:

     Development.  Through the office of the CTO and the development groups
located at various facilities, Hadco identifies, develops and markets new
technologies that benefit its customers. The CTO and the development groups work
closely with customers during all stages of product life cycles. For instance,
process design changes and refinements required for volume production are
identified and implemented prior to production. The CTO and the development
groups also focus on the special requirements of the Company's customers,
including increasing printed circuit densities, embedded passive components and
advanced materials and products.

     Design.  The Company provides design and engineering assistance in the
early stages of product development, which assures both mechanical and
electrical considerations are integrated to achieve a high quality and cost
effective product. The Company also evaluates customer designs for
manufacturability and, when appropriate, recommends design changes to reduce
manufacturing costs or lead times or to increase manufacturing yields or the
quality of finished printed circuits. The Company believes that this long-term
view of manufacturing and customer relationships distinguishes the Company from
many manufacturers which compete primarily in the quick-turn market. By working
closely with its customers, the Company also gains a better understanding of the
future requirements of OEMs. 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 to customer premises in a
timely fashion.

     Quick-Turn Prototype.  Prototypes typically require lead times of three to
seven days, and as short as 24 hours. The Company provides quick-turn prototype
services to the product development groups of customers that require small test
quantities. Hadco offers these services through facilities in Massachusetts,
Texas and California. Prototype development at these facilities has included
multilayer printed circuits of up to 50 layers, embedded discrete components,
heavy copper substrates, sequential lamination, cavity substrates, thermal

                                        2

management products, Single Chip Carriers (SCC), planar magnetics, advanced
surface finishes and various high performance substrates for the high frequency
microwave market. These facilities also support advanced attachment technologies
such as Direct Chip Attach (DCA) and High Density Interconnect (HDI). In
combining the design of a printed circuit with the manufacture of the prototype,
Hadco can reduce the length of the design/manufacture cycle. By working closely
with customers at the design and prototype stage, the Company believes it
strengthens long-term relationships with its customers and gains an advantage in
securing a preferred vendor status when customers begin volume production.

     Pre-Production.  Pre-production is the manufacture of limited quantities of
electronic interconnects during the transition period from prototype to volume
production. Pre-production generally requires quick-turn delivery to accommodate
time-to-volume pressures or as a temporary solution for unforeseen customer
demands. Pre-production is done both in the quick-turn prototype and volume
production facilities.

     Volume Production.  Volume production is characterized by longer lead times
and increased emphasis on lower cost as the product moves to full-scale
commercial production. As customers increasingly demand a quick transition from
prototype to volume production, few independent manufacturers can provide
complex printed circuits of 20 or more layers in the volume provided by Hadco's
larger facilities. The Company operates six facilities located in California,
New York, New Hampshire, Arizona and Malaysia for medium-and high-volume printed
circuit production.

     Backplane and System Assembly.  Backplanes are generally larger and thicker
printed circuits on which connectors are mounted to interconnect printed
circuits, integrated circuits and other electronic components. System assemblies
include the backplane, power supply, fan card, cabling and system chassis. Hadco
incorporates its own printed circuits in backplane and system assemblies to
provide customers with a high level of printed circuit technology on a
quick-turn and volume basis. Net sales of backplane and system assemblies
accounted for approximately 11%, 16%, and 18% of total Company net sales during
fiscal 1997, 1998 and 1999, respectively. See Note 14 of Notes to Consolidated
Financial Statements. With its backplane and system assembly operations, Hadco
is one of a few companies that provides its customers with the advantage of an
integrated offering to meet their needs from development and design through
volume production to backplane and system assembly.

     The Company's advanced process capabilities enhance each of the above
services and include:

     Manufacture of High Performance Printed Circuits.  At its quick-turn
prototype and volume production facilities, the Company produces technologically
advanced printed circuits primarily for the high performance market. These
printed circuits, used principally in the data communications and
telecommunications industries, are designed to function at high frequencies with
excellent reliability. Materials used by the Company for these products include
high T(g), epoxy, Teflon(R), cyanate ester, GETEK(R), epoxy/polyphenylene oxide,
polyimides, and bismaleimide triazine epoxies.

     Development of Emerging Technologies.  The Company undertakes projects to
develop advanced or improved processes, materials and product lines. Buried
Capacitance(TM) is an advanced material developed by the Company to provide
improved electrical performance and greater interconnect densities. The Company
receives revenue from sales of products containing this technology, as well as
net royalty income from licensing its use. In addition, the Company is
developing various microvia processes, which include horizontal plating, plasma
etching and laser drilling. Microvias provide a significant increase in printed
circuit interconnect density and performance. The Continental Acquisition added
PCA Design's microvia design methodology. The Company also produces rigid flex
printed circuit products utilizing licensed HVRFlex(TM) technology. These
products enable customers to fold a printed circuit and reduce the need for
cable connectors in the portable computer and telecommunications markets. See
Item 2, "Manufacturing and Facilities."

     The Company supplied its products and services to a diverse base of
approximately 740 customers in fiscal 1999, including 77 customers with
purchases in excess of $1 million. The Company attempts to market its products
to customers that currently have, or have the potential to achieve, significant
market share in their respective industries. The following were the Company's
largest customers in fiscal 1999:

<TABLE>
<S>                                     <C>
*Avex Electronics                       *Hewlett Packard

*Compaq Computer                        *Solectron
</TABLE>

     During fiscal 1997, 1998 and 1999, one customer, Solectron, accounted for
approximately 15%, 17% and 15%, respectively, of Hadco's net sales. The
Company's ten largest customers together accounted for approximately 47%, 51%
and 56% of the Company's net sales, respectively, during the same periods. See
Note 13 of Notes to Consolidated Financial Statements.

     The Company generally does not obtain long-term purchase orders or
commitments from its customers, and the orders received by the Company generally
require delivery within 90 days. However, many of the Company's customers have
maintained long-term purchasing relationships with the Company. See Item 7,
"Factors That May Affect Future Results -- Risks Relating to Variability of
Orders from Customers; Backlog."

     During fiscal 1999, 22.7% of the Company's net sales were attributable to
sales outside of the United States, principally in Singapore, Canada and Europe.
The Company intends to expand its sales efforts outside of the United States.
See Note 14 of Notes to Consolidated Financial Statements.

SALES AND MARKETING

     The Company markets its products through its own sales and marketing
organization and independent manufacturers' representatives. The Company is
represented by independent manufacturers' representatives located in North
America, South America, Europe, Mexico, South Africa, Asia, Australia, New
Zealand and the Middle East. Regional direct sales offices are located
throughout North America, and in Ireland and Singapore. In addition, the Miami,
Florida sales office provides sales support for Latin America. The Company's
sales organization also has a support staff of sales engineers and technical
service personnel responsible for technical liaison and problem solving, market
research and marketing communications.

                                        4
<PAGE>   6

     The Company focuses on developing close relationships with customers
beginning at the earliest development and design phases and continuing
throughout all stages of product production. The Company identifies, develops
and markets new technologies that benefit its customers and are intended to
position the Company as an important source for these solutions. The Company
hosts regional technology symposiums at which the Company's technical
capabilities are presented to, and industry technical trends are discussed with,
its customers.

SUPPLIER RELATIONSHIPS

     Historically, the majority of raw materials used in the Company's
manufacture of printed circuits and components used in backplane and system
assemblies have been readily available. However, product changes and the overall
demand for electronic interconnect products could increase the industry's use of
new laminate materials, multilayer blanks, laser drilling, mechanical drilling,
non-standard surface finishes, electronic components and other materials and
services, and therefore such materials and services may not be readily available
to the Company in the future. The Company believes that the potential exists for
a shortage of materials and services in the printed circuit and electronic
assembly industries which could have a material adverse effect on the Company's
manufacturing operations and future unit costs. In response to such concerns,
the Company engages in the normal industry practice of maintaining primary and
secondary vendors. There can be no assurance that shortages of certain types of
raw materials, manufacturing services, or components or price fluctuations will
not occur in the future. See Item 7, "Factors That May Affect Future Results --
Risks of Inability to Obtain Raw Materials and Components."

     The Company works with its suppliers to develop just-in-time supply systems
which reduce inventory carrying costs. The Company also maintains a Supplier
Certification Program which evaluates potential vendors on the basis of such
factors as quality, on-time delivery, cost, technical capability, and potential
technical advancement. Certification is based on both actual performance and
audits of vendors' manufacturing sites. Key suppliers are reviewed quarterly to
preserve strong relationships with these suppliers and maintain regular dialogue
on quality, cost and technical advancement issues.

COMPETITION

     The electronic interconnect industry is highly fragmented and characterized
by intense competition. The Company believes that its major competitors are the
large U.S. and international independent and captive producers that also
manufacture multilayer printed circuits and provide backplane and other
electronic assemblies. Some of these competitors have significantly greater
financial, technical and marketing resources, greater name recognition and a
larger installed customer base than the Company. 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
the Company. Hadco competes on the basis of product quality, timeliness of
delivery, price, customer technical support and its integrated offering, from
development and design through volume production to backplane and system
assembly.

     During periods of recession or economic slowdown in the electronics
industry and other periods when excess capacity exists, EMS providers and OEMs
are able to negotiate lower prices, which could have a material adverse effect
on the Company's business, financial condition and results of operations. In
addition, the Company believes that price competition from printed circuit
manufacturers in Asia and other locations with lower production costs may play
an increasing role in the printed circuit markets in which the Company competes.
This price competition from Asian printed circuit manufacturers may intensify as
a result of economic turmoil, currency devaluations or financial market
instability that many Asian countries have experienced in the past. The
Company's basic interconnect technology is generally not subject to significant
proprietary protection, and companies with significant resources or
international operations may enter the market. Increased competition could
result in price reductions, reduced margins or loss of market share, any of
which could materially adversely affect the Company's business, financial
condition and results of operations.

     The demand for printed circuits has continued to be affected by the
development of smaller, more powerful electronic components requiring less
printed circuit area. Expansion of the Company's existing

                                        5
<PAGE>   7

products or services could expose the Company to new competition. Moreover, new
developments in the electronics industry could render existing technology
obsolete or less competitive and could potentially introduce new competition
into the industry. There can be no assurance that the Company will continue to
compete successfully against present and future competitors or that competitive
pressures faced by the Company will not have a material adverse effect on the
Company's business, financial condition and results of operations.

PRODUCT PROTECTION

     The Company has obtained 13 United States patents and 33 foreign patents
directed to printed circuit boards and methods of manufacturing printed circuit
boards which expire between the years 2009 through 2014. Although Hadco seeks to
protect certain proprietary technology and other intangible assets through
patents and trademark filings, it has relatively few patents and relies
primarily on trade secret protection. There can be no assurance that the Company
will be able to protect its trade secrets or that others will not independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to the Company's trade secrets. The future success of the
Company will depend on the continued development of processes and capabilities.
The Company believes that its accumulated experience with respect to materials
and process technology is also important to its operations. See Item 3, "Legal
Proceedings and Claims."

RELEASED BACKLOG

     The Company's released backlog as of October 30, 1999 was $148.7 million,
compared with $140.1 million as of October 31, 1998. Released backlog consists
of orders for which artwork has been received, a delivery date has been
scheduled and which the Company anticipates it will manufacture and deliver. The
Company anticipates delivering approximately 92% of its released backlog during
the first quarter of fiscal 2000. Cancellation and postponement charges, to the
extent they exist with respect to released backlog, generally vary depending
upon the time of cancellation or postponement, and a significant portion of the
Company's released backlog at any time may be subject to cancellation or
postponement without penalty. Variations in the size, timing and delivery
schedules of purchase orders received by the Company, as well as changes in
customers' delivery requirements, may result in substantial fluctuations in
released backlog from period to period. Accordingly, the Company believes that
released backlog is not a meaningful indicator of future quarterly or annual
financial results.

     As of October 30, 1999, the Company had 7,850 employees compared to 7,673
employees as of October 31, 1998. The employees are not represented by a union,
and the Company has never experienced any labor problems resulting in a work
stoppage.

ENVIRONMENTAL MATTERS

     The Company is required to comply with all federal, state, county and
municipal regulations regarding protection of the environment. There can be no
assurance that more stringent environmental laws will not be adopted in the
future and, if adopted, the costs of compliance with more stringent
environmental laws could be substantial. Waste treatment and disposal are major
considerations for printed circuit manufacturers. The Company uses chemicals in
the manufacture of its products that are classified by the Environmental
Protection Agency (EPA) as hazardous substances. The Company is aware of certain
chemicals that exist in the ground at certain of its facilities. The Company has
notified various governmental agencies and continues to work with them to
monitor and resolve these matters. During March 1995, the Company received a
Record Of Decision (ROD) from the New York State Department of Environmental
Conservation (NYSDEC), regarding soil and groundwater contamination at its
Owego, New York facility. Based on a Remedial Investigation and Feasibility
Study (RIFS) for apparent on-site contamination at that facility and a Focused
Feasibility Study (FFS), each prepared by environmental consultants of the
Company, the NYSDEC has approved a remediation program of groundwater withdrawal
and treatment and iterative soil flushing. The Company has executed a
Modification of the Order on Consent to implement the approved ROD. Capital


                                        6
<PAGE>   8

equipment for this remediation has already been acquired by the Company, and
future operation and maintenance costs, which will be incurred and expended over
the estimated life of the program of the next 28 years, are estimated at between
$40,000 and $100,000 per year. In the summer of 1998, NYSDEC took additional
samples from a wetland area near the Company's Owego facility. Analytical
reports of earlier sediment samples indicated the presence of certain
inorganics. The new samples showed elevated levels of certain metals, but NYSDEC
has not made a determination as to the potential source of such metals, the
remedial action to be taken, or the persons to undertake and/or pay for any
remediation. There can be no assurance that the Company and/or other third
parties will not be required to conduct additional investigations and
remediation at that location, the costs of which are currently indeterminable
due to the numerous variables described in the fourth paragraph of this
"--Environmental Matters" section.

     See Item 3, "Legal Proceedings and Claims" for a discussion of certain
environmental matters relating to a printed circuit manufacturing facility
formerly operated by the Company in Florida.

     The Company commenced the operation of a groundwater extraction system at
its Derry, New Hampshire facility to address certain groundwater contamination
and groundwater migration control issues. Further investigation is underway to
determine the areal extent of the groundwater contaminant plume. Because of the
uncertainty regarding both the quantity of contaminants beneath the building at
the site and the long-term effectiveness of the groundwater migration control
system the Company has installed, it is not possible to make a reliable estimate
of the length of time remedial activity will have to be performed. However, it
is anticipated that the groundwater extraction system will be operated for at
least 30 years. There can be no assurance that the Company will not be required
to conduct additional investigations and remediation relating to the Derry
facility. The total costs of such groundwater extraction system and of
conducting any additional investigations and remediation relating to the Derry
facility are not fully determinable due to the numerous variables described in
the next paragraph.

     The Company accrues estimated costs associated with known environmental
matters when such costs can be reasonably estimated. The cost estimates relating
to future environmental clean-up are subject to numerous variables, the effects
of which can be difficult to measure, including the stage of the environmental
investigations, the nature of potential remedies, possible joint and several
liability, the magnitude of possible contamination, the difficulty of
determining future liability, the time over which remediation might occur, and
the possible effects of changing laws and regulations.

     Management believes the ultimate disposition of above known environmental
matters described in this "--Environmental Matters" section 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. See Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and Note 9 of Notes to the Company's Consolidated Financial
Statements.

     The Company plans additional capital expenditures during fiscal 2000 to
further reduce air emissions and reduce waste generation. See discussion under
Item 2, "Manufacturing and Facilities" concerning the Company's capital
expenditures relating to environmental control facilities and equipment, and
under Item 3, "Legal Proceedings and Claims" relating to lawsuits regarding
environmental matters.

ITEM 2.  MANUFACTURING AND FACILITIES

     The need for high volume production of dense multilayer printed circuits
requires complex manufacturing processes and necessitates high levels of
investment in facilities, materials, production processes and product design
capabilities. The Company employs numerous advanced manufacturing techniques and
systems including Computer Aided Manufacturing (CAM) systems, Computer
Integrated Manufacturing (CIM) systems, computer controlled laser and mechanical
drilling, routing and scoring systems, dry film and laser direct imaging,
automated optical inspection, computer-controlled high-volume lamination in high
pressure and temperature presses, computer-controlled horizontal and vertical
plating systems, direct current and reverse pulse plating, high-volume liquid
photoimageable solder mask surface coating, various specialty finishes, and
high-density electrical testers. These techniques enable Hadco to manufacture
multilayer printed

                                        7
<PAGE>   9

circuits of consistent quality, in high volume and on a timely basis. All of the
Company's production facilities are ISO9002 certified. See Item 1, "Business --
Products and Services."

     In the backplane and system assembly segment, Hadco utilizes sophisticated
automated connector placement equipment and high-capability surface mount
systems to meet the escalating demand for high mix, prototype and volume
assemblies. The Company has also invested in the resources to facilitate
materials acquisition and logistics requirements, both of which the Company
considers important to maintaining competitive service levels.

     In total, the Company leases or owns approximately 1.8 million square feet
of manufacturing space. The Company's significant facilities are as follows:

     The lease for the warehouse space in San Jose, California extends for ten
years from commencement of the lease term for the entire area subject to the
lease, and commencement of the lease term has not yet occurred. The Company is
currently in early occupancy of 51,000 square feet of warehouse space. The lease
includes one option to extend for an additional five-year term.

     Additionally, the Company owns approximately six acres of land in Salem,
New Hampshire, approximately five acres of land in Derry, New Hampshire,
approximately 29 acres of land in Owego, New York and approximately four acres
of land in Phoenix, Arizona.

     The Company believes its facilities are currently adequate for its
operating needs.

     In fiscal 1999, the Company's capital expenditures relating to its
environmental control facilities and equipment totaled approximately $3.6
million. The Company estimates that it will make capital expenditures with
respect to its environmental control facilities and equipment of approximately
$3 million and $2 million in fiscal 2000 and 2001, respectively.

ITEM 3.  LEGAL PROCEEDINGS AND CLAIMS

     The Company is one of 33 entities which have been named as potentially
responsible parties in a lawsuit pending in the federal district court of New
Hampshire concerning environmental conditions at the Auburn Road, Londonderry,
New Hampshire landfill site. Local, state and federal entities and certain other
parties to the litigation seek contribution for past costs, totaling
approximately $20 million, allegedly incurred to assess and remediate the Auburn
Road site. In December 1996, following publication and comment period, the EPA
amended the ROD to change the remedy at the Auburn Road site from active
groundwater remediation to future monitoring. In June 1999, the Company entered
into a Consent Decree with 30 of the defendants and third-party defendants. The
Consent Decree was approved by the federal and state governments in December
1999, and lodged with the Court. The Court must still approve the Consent
Decree. Under the terms of the Consent Decree, the Company is a cash-out party
and does not have responsibility for performance of ongoing remedial or
monitoring work at the site.

     From 1974 to 1980, the Company operated a printed circuit manufacturing
facility in Florida as a lessee. This property is the subject of a pending
lawsuit in the circuit court for Broward County, Florida (the "Florida Lawsuit")
and an investigation by the Florida Department of Environmental Protection
("FDEP"). In connection with the investigation, Hadco and others have
participated in alternative dispute resolution regarding the site with an
independent mediator. Mediation sessions began in 1992 and continued over the
next several years through May 1998. In June 1995, Hadco and Gould, Inc.,
another prior lessee of the site, were joined as third-party defendants in the
pending Florida lawsuit by a party who had previously been named as a defendant
when the Florida lawsuit was commenced in 1993 by the FDEP. As a result of the
mediation, a Settlement Agreement was entered into among Hadco, Gould and the
FDEP in March 1999. The third-party complaints against Hadco and Gould in the
pending Florida lawsuit were dismissed. The Settlement Agreement provides that
Hadco and Gould will undertake remedial action based on a Supplemental
Contamination Assessment Report and a later Feasibility Study, which has been
prepared by a consultant to Hadco and Gould and approved by the FDEP. The
estimated cost of the recommended source removal described in the Feasibility
Study is approximately $165,000, and for ongoing monitoring and remediation is
approximately $2.1 million. Actual remedial activities have not yet commenced
but are expected to begin in the near future.

     In March 1993, the EPA notified Hadco Santa Clara of its potential
liability for maintenance and remediation costs in connection with a hazardous
waste disposal facility operated by Casmalia Resources, a California Limited
Partnership, in Santa Barbara County, California. The EPA identified Hadco Santa
Clara as one of the 65 generators which had disposed of the greatest amounts of
materials at the site. Based on the total tonnage contributed by all generators,
Hadco Santa Clara's share is estimated at approximately 0.2% of the total
weight.

     The Casmalia site was regulated by the EPA during the period when the
material was accepted. There is no allegation that Hadco Santa Clara violated
any law in the disposal of material at the sites. Rather the

                                        9
<PAGE>   11

EPA's actions stemmed from the fact that Casmalia Resources may not have the
financial means to implement a closure plan for the site and because of Hadco
Santa Clara's status as a generator of hazardous waste.

     In June 1997, the United States District Court in Los Angeles, California
approved and entered a Consent Decree among the EPA and 49 entities (including
Hadco Santa Clara) acting through the Casmalia Steering Committee (CSC). The
Consent Decree sets forth the terms and conditions under which the CSC will
carry out work aimed at final closure of the site. Certain closure activities
will be performed by the CSC. Later work will be performed by the CSC, if funded
by other parties. Under the Consent Decree, the settling parties will work with
the EPA to pursue the non-settling parties to ensure they participate in
contributing to the closure and long-term operation and maintenance of the
facility.

     The EPA will continue as the lead regulatory agency during the final
closure work. Because long-term maintenance plans for the site will not be
determined for a number of years, it has not yet been decided which regulatory
agency will oversee this phase of the work plan or how the long-term costs will
be funded. However, the Consent Decree provides a mechanism for ensuring that an
appropriate federal, state or local agency will assume regulatory responsibility
for long-term maintenance.

     On January 12, 1998, Hadco Santa Clara received notice of the filing of a
lawsuit, before the Superior Court (County of Santa Clara, California), against
it by Jackie Riley, Keith Riley and Richard Riley for damages (including
punitive damages) for alleged injuries suffered, including Richard Riley's
cancer, as a result of the alleged emission at the Hadco Santa Clara facility of
effluent from allegedly toxic and hazardous chemical substances. In October
1999, the court approved a settlement of this litigation. The Company has
performed all its obligations under the settlement.

     The future costs in connection with the lawsuits described in the preceding
paragraphs, which arise under state and federal laws that impose legal liability
that may be joint and several, are currently indeterminable due to such factors
as the unknown timing and extent of any future remedial actions which may be
required, the extent of any liability of the Company and of other potentially
responsible parties, and the financial resources of the other potentially
responsible parties. See Note 9 of Notes to the Company's Consolidated Financial
Statements.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of the Company's security holders
during the fourth quarter of the fiscal year ended October 30, 1999.

ACQUISITIONS

     On January 10, 1997, the Company acquired all of the outstanding capital
stock of Zycon. The acquisition added facilities for volume production of
multilayer printed circuits and backplane and system assemblies in the Silicon
Valley area, a quick-turn prototype and design facility in Massachusetts, and a
newly constructed facility for volume production of printed circuits in
Malaysia. Hadco acquired Zycon for approximately $212 million (including
acquisition costs) and recorded the acquisition under the purchase method of
accounting. As a result, a purchase price premium of approximately $182 million
was recorded on the transaction. A significant portion of the purchase price was
identified in an independent appraisal, using proven valuation procedures and
techniques, as intangible assets. These intangible assets included approximately
$78 million for acquired in-process research and development ("in-process R&D")
for projects that did not have future alternative uses. This allocation
represents the estimated fair market value based on risk-adjusted cash flows
related to the in-process R&D projects. At the date of acquisition, the
development of these projects had not yet reached technological feasibility, and
the in-process R&D had no alternative future uses. Accordingly, these costs were
written off in the fiscal quarter ended January 25, 1997. The remaining premium
of approximately $104 million was allocated to identifiable intangibles and
goodwill, and is being written off over 12 to 30 years, with an average
amortization period of 17 years. The acquisition was financed with borrowings
under the Credit Facility, plus existing cash and equivalents.

     On March 20, 1998, the Company acquired all of the outstanding capital
stock of Continental, further broadening Hadco's product and service
capabilities. The acquisition added a facility for volume production of
multilayer printed circuits in Phoenix, Arizona, a quick-turn prototype facility
in Austin, Texas, a flexible printed circuit facility in California (which was
sold on April 30, 1999) and printed circuit engineering and design sites in
California, Texas and Colorado. Hadco acquired Continental for approximately
$190 million (including acquisition costs) and recorded the acquisition under
the purchase method of accounting. As a result, a purchase price premium of $165
million was recorded on the transaction. A significant portion of the purchase
price was identified in an independent appraisal, using proven valuation
procedures and techniques, as intangible assets. These intangible assets
included approximately $63 million for in-process R&D for projects that did not
have future alternative uses. This allocation represents the estimated fair
market value based on risk-adjusted cash flows related to the in-process R&D
projects. At the date of acquisition, the development of these projects had not
yet reached technological feasibility, and the in-process R&D had no alternative
future uses. Accordingly, these costs were written off in the fiscal quarter
ended May 2, 1998. The remaining premium of $101.9 million was allocated to
identifiable intangibles and goodwill, and is being written off over 12 to 20
years, with an average amortization period of 17 years. The acquisition was
financed from borrowings under the Credit Facility.

</TABLE>

- ---------------
(1) Net loss for the year ended October 25, 1997 includes a non-recurring
    write-off relating to the Zycon Acquisition for acquired in-process research
    and development. As a percentage of net sales, income from operations was
    11.8%, income before provision for income taxes was 10.7%, and net income
    was 6.4%, all before deducting the non-recurring write-off.

(2) Net loss for the year ended October 31, 1998 includes a non-recurring
    write-off relating to the Continental Acquisition for acquired in-process
    research and development and for restructuring and other non-recurring
    expenses. As a percentage of net sales for the year ended October 31, 1998,
    income from operations was 5.1%, income before provision for income taxes
    was 2.6%, and net income was 1.6%, all before deducting the non-recurring
    write-off and restructuring charges.

  Fiscal Years Ended October 30, 1999 and October 31, 1998

     Net sales for fiscal 1999 increased 21.7%, or $179.6 million over net sales
for fiscal 1998. The increase resulted from several factors including a full
year of sales from the Continental Acquisition, which added $71.7 million to
printed circuit net sales. Excluding the Continental Acquisition, printed
circuit net sales increased $60.0 million 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 3.7%
decline in average pricing for printed circuits. Backplane and system assembly
net sales increased $47.9 million to $178.5 million. Backplane and system
assembly net sales increased due to higher production volumes and shipments.

     The gross profit margin increased to 15.6% for fiscal 1999 from 15.0% in
fiscal 1998. Improved capacity utilization from both printed circuit and
assembly operations caused gross margins to increase 3.4 percentage points, and
improved production efficiencies in printed circuit operations caused gross
margins to increase by 0.3 percentage points. These increases in gross margin
were offset by lower pricing on printed circuits, which decreased gross margins
by 2.7 percentage points, and a shift in mix in assembly operations to products
with higher material content which caused gross margins to decrease by 0.4
percentage points.

     Operating expenses increased by $9.3 million for fiscal 1999 over fiscal
1998. The increase was due to a full year of amortization of goodwill and
purchased intangibles from the Continental Acquisition, and higher selling
expenses from expanded sales coverage. Operating expenses as a percent of net
sales decreased to 9.0% for fiscal 1999 versus 9.9% for fiscal 1998 due to
increased net sales and the relatively fixed nature of the Company's operating
expenses.

     Income from operations for the year ended October 30, 1999 increased by
$94.0 million over fiscal 1998. However, fiscal 1998 income from operations was
reduced by $63.0 million due to a non-recurring write-off of acquired in-process
research and development recorded in connection with the Continental
Acquisition. In addition, income from operations for the year ended October 31,
1998 was reduced by approximately $7.1 million for restructuring and other
non-recurring charges related to the consolidation of the Company's East Coast
Tech Center operations and a limited restructuring of the Company's workforce.

     Excluding the non-recurring write-off and restructuring charges during
fiscal 1998, income from operations increased as a percent of net sales to 6.6%
for the year ended October 30, 1999 from 5.1% in fiscal 1998. The increase
resulted primarily from the same factors affecting gross profit margins plus
increased leverage of operating expenses.

                                       14
<PAGE>   16

     Interest income decreased for the year ended October 30, 1999 as compared
to the prior fiscal year due to lower average cash balances available for
investing. Interest expense increased in the year ended October 30, 1999 as
compared to the year ended October 31, 1998 due to a full year of interest
expense on outstanding debt to finance the Continental Acquisition.

     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. See Item 1, "Business -- Environmental Matters" and Item 3, "Legal
Proceedings and Claims."

     The Company's effective annual income tax rate for 1998 and 1999 was
39.75%. The provision for income taxes is calculated on income before provision
for taxes without taking into account the write-off of acquired in-process R&D
of $63.0 million. Income before the provision for income taxes excluding the
write-off would have been $14.8 million for 1998. The effective rate for both
years is approximately equal to the combined federal and state statutory rates.
The effective rate was increased by amortization of goodwill, which is not tax
deductible, and was offset by the tax benefit of the Company's foreign sales
corporation and various state investment tax credits.

  Fiscal Years Ended October 31, 1998 and October 25, 1997

     Net sales for fiscal 1998 increased 27.4%, or $177.7 million, over net
sales for fiscal 1997. The increase resulted from several factors including the
Continental Acquisition, which added $80.4 million to printed circuit net sales.
Excluding the Continental Acquisition, printed circuit net sales increased $36.6
million, due to higher production volume and shipments as well as the shift
towards printed circuits with more layers and greater densities. This increase
in printed circuit net sales was partially offset by a 10.3% decrease in average
pricing. Backplane and system assembly net sales increased $60.7 million to
$130.6 million. Backplane and system assembly net sales increased due to higher
production volume and shipments.

     The gross profit margin decreased to 15.0% in 1998 from 21.8% in 1997.
Lower pricing on printed circuits caused margins to decrease by 5.8 percentage
points. Lower capacity utilization from printed circuit operations caused
margins to decrease by 1.7 percentage points. The effect of lower overall gross
margins from Hadco Santa Clara and Hadco Phoenix operations caused margins to
decrease by 2.0 percentage points. All of these decreases were partially offset
by lower unit costs achieved through improved production efficiencies resulting
in an overall decrease in the gross margin of 6.8 percentage points.

     Operating expenses, as a percent of net sales, decreased slightly to 9.9%
in fiscal 1998 from 10.0% in fiscal 1997. This decrease was partially offset by
goodwill and purchased intangibles amortization of $9.7 million in fiscal 1998
as compared to $5.2 million in 1997. For additional information regarding the
factors affecting gross and operating margins, please see "Factors That May
Affect Future Results -- Risks Relating to Fluctuations in Quarterly Operating
Results," "Factors That May Affect Future Results -- Dependence on Electronics
Industry" and "Factors That May Affect Future Results -- Risks Relating to the
Acquisitions and the Company's Acquisition Strategy."

     Income from operations for 1998 and 1997 was reduced by $63.0 million and
$78.0 million, respectively, due to non-recurring write-offs of acquired
in-process R&D recorded in connection with the Acquisitions. The remaining
goodwill and purchased intangibles are being amortized over 12 to 30 years, with
an average amortization period of 17 years, which will reduce income from
operations by approximately $12.2 million per fiscal year. In addition, income
from operations for 1998 was reduced by approximately $7.1 million for
restructuring and other non-recurring charges related to the consolidation of
the Company's East Coast quick-turn prototype operations and limited
restructuring of the Company's workforce. The limited restructuring in the third
fiscal quarter temporarily reduced the Company's workforce by approximately 3%.
Included in the restructuring and other charges is $2.5 million, which
represents the write-down of existing assets to their net realizable value, in
accordance with SFAS 121, Accounting for the Impairment of Long-Lived Assets and
Long-Lived Assets to be Disposed Of. See Note 15 of Notes to the Company's
Consolidated Financial Statements. Additionally, the general economic slowdown
in the broad electronics industry, the economic

                                       15
<PAGE>   17

situation in Asia, inventory levels in the end user market, customer inventory
adjustments and customer product transitions negatively affected net income for
fiscal 1998.

     Interest income decreased in 1998 as compared to 1997, due to lower average
daily cash balances available for investing. Interest expense increased in 1998
as compared to 1997, due to an increase in outstanding debt as a result of the
Acquisitions.

     The provision for income taxes is calculated on income before provision for
taxes without taking into account the write-off of acquired in-process R&D. This
write-off was $63.0 million and $78.0 million for 1998 and 1997, respectively.
Income before the provision for income taxes excluding the write-off would have
been $14.8 million and $69.2 million for 1998 and 1997, respectively. The
Company's effective annual income tax rate for 1998 and 1997 was 39.75% and
40.0%, respectively. The effective rate for both years is approximately equal to
the combined federal and state statutory rates. The effective rate was increased
by amortization of goodwill, which is not tax deductible, and was offset by the
tax benefit of the Company's foreign sales corporation and various state
investment tax credits.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash flow from operations for fiscal 1999 was $146.2 million, an
increase of $83.3 million from the prior year. This increase resulted from an
increase of $22.1 million in earnings before non-cash items, the receipt of
$17.5 million in income tax refunds, and improved working capital management.
The increased earnings were attributable to higher net sales and increased
production efficiencies. Improvements in working capital management include
faster collections of accounts receivable, increased turnover of inventory, and
extended credit terms with suppliers.

     Cash used in investing activities in fiscal 1999 was $71.6 million, a
decrease of $204.5 million from fiscal 1998. Reduced investing activities
combined with increased cash flow from operations resulted in increased cash
available to reduce debt incurred to finance the Acquisitions. Debt reductions
during fiscal 1999 were $77.8 million.

     At October 30, 1999, the Company had working capital of $47.8 million and a
current ratio of 1.30, as compared to working capital of $91.8 million and a
current ratio of 1.71 at October 31, 1998. The decrease in working capital
resulted from the collection of $17.5 million in income tax refunds and
improvements in working capital management that accelerated the conversion of
working capital into cash, which was, in turn, used to reduce debt.

     Net cash flow from operations for fiscal 1998 was $62.9 million, an
increase of $12.3 million from the prior year. This increase resulted from
improved working capital management, including faster collection of accounts
receivable. This increase was partially offset by a reduction in earnings before
non-cash items of $4.6 million. The reduction in earnings was attributable to
lower pricing and lower capacity utilization for printed circuit operations, as
a result of the slowdown of the electronics industry experienced during fiscal
1998.

     Cash used in investing activities in fiscal 1998 was $276.0 million, a
decrease of $0.7 million from the prior year. Fiscal 1998 investing activities
included capital expenditures of $83.5 million and the Continental Acquisition
for $192.5 million. These investing activities were financed from cash flow from
operations plus a net increase in indebtedness of $200.9 million.

     The Company seeks to reduce reliance on debt financing and to reduce the
costs associated with maintaining its Credit Facility. The Credit Facility
commitment was reduced from the lesser of $288.8 million or the Borrowing Base
(as defined in the Credit Facility) to the lesser of $198.8 million or the
Borrowing Base, on May 14, 1999. As of October 30, 1999, the Company had $75.0
million in outstanding borrowings under the Credit Facility at a weighted
average interest rate of 6.31%, with up to a maximum of $123.8 million of the
Credit Facility unused and available. For a further discussion of the Credit
Facility see Note 7 of Notes to the Company's Consolidated Financial Statements.

                                       16

     On May 18, 1998, the Company sold $200 million aggregate principal amount
of its 9 1/2% Senior Subordinated Notes due 2008 (the "Notes") to certain
purchasers. The Notes were sold at a price equal to 99.66% of their principal
amount. The net proceeds received by the Company from the issuance and sale of
the Notes was used to repay outstanding indebtedness under the Credit Facility
previously incurred to, among other things, finance the Acquisitions. On
November 12, 1998, the Company consummated an exchange offer pursuant to which
the Notes were exchanged for notes (with terms identical in all material
respects) that were registered with the Securities and Exchange Commission. For
a further discussion of the Notes, see Note 8 to the Company's Consolidated
Financial Statements.

     The Company currently anticipates that its capital expenditures for fiscal
2000 will be between $90 and $100 million. At October 30, 1999, the Company had
$10.6 million of future commitments to purchase manufacturing equipment and
leasehold improvements. The amount of these anticipated capital expenditures may
change based on future changes in business plans and conditions of the Company
and changes in economic conditions.

     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

     The Company has completed an internal assessment of its operations to
determine the extent to which the Company may be adversely affected by Year 2000
issues. This internal assessment has 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 believes that none
of these applications have date-related processing issues. The Company has
experienced and may continue to experience interfacing problems when upgrades
are received from the vendors of these software programs.

     The Company has completed testing of its various IT systems, running
programs with dates including and after the Year 2000. During these tests the
Company has not experienced problems processing data or effecting transactions.
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 has tested the new software and has not encountered 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 operation and financial condition.

     In fiscal 1999, the Company developed business continuity/contingency plans
for all 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.

     The Company has surveyed most of its suppliers, including all of its active
suppliers, to determine their Year 2000 compliance status. The Company has
worked with its key suppliers to obtain more detailed information about their
compliance status, and has performed on-site assessment of certain critical
suppliers. The Company has also completed contingency plans for addressing
potential supply disruptions. There can be


                                       17
<PAGE>   19

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.

     To date, approximately 29,400 hours of employee time have been devoted to
Year 2000 issues and approximately $5.8 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. Present estimates for further expenditures of
both employee time and expenses to address Year 2000 matters, which include but
are not limited to year-end coverage and equipment upgrades, are between 1,000
and 1,500 hours and between $75,000 and $100,000. There can be no assurance that
the Company's costs relating to its Year 2000 compliance will not be greater
than that currently expected.

     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 customer. 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.

NEW ACCOUNTING STANDARDS

     In June 1999, the Financial Accounting Standards Board (FASB) issued SFAS
No. 137, Accounting for Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of SFAS No. 133, which defers the
effective date of SFAS No. 133 to all fiscal quarters of all fiscal years
beginning after June 15, 2000. SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires entities to
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. The Company does
not anticipate the adoption of these Statements will have a material impact on
its financial position or results of operations.

FACTORS THAT MAY AFFECT FUTURE RESULTS

     This Annual Report on Form 10-K contains forward-looking statements which
involve risks and uncertainties. The Company's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including, without limitation, those set forth in the
following risk factors and elsewhere in this Annual Report on Form 10-K. In
addition to the other information included or incorporated by reference in this
Annual Report on Form 10-K, the following risk factors should be considered
carefully in evaluating the Company and its business.

  Dependence on Electronics Industry

     The Company's principal customers are EMS providers and OEMs in the
computing (mainly workstations, servers, mainframes, storage and notebooks),
data communications/telecommunications and industrial automation industries,
including process controls, automotive, medical and instrumentation. These
industry segments, and the electronics industry as a whole, are characterized by
intense competition, relatively short product life-cycles and significant
fluctuations in product demand. In addition, the electronics industry is
generally subject to rapid technological change and product obsolescence.
Discontinuance or modifications of products containing components manufactured
by the Company could have a material adverse effect on the Company's business,
financial condition and results of operations. Further, the electronics industry
is subject to economic cycles and has in the past experienced, and is likely in
the future to experience, recessionary periods. A recession or any other event
leading to excess capacity or a downturn in the electronics industry


                                       18
<PAGE>   20

would likely result in intensified price competition, reduced gross margins and
a decrease in unit volume, all of which would have a material adverse effect on
the Company's business, financial condition and results of operations. See Item
7, "Management's Discussion and Analysis of Financial Condition and Results of
Operations," and Item 1, "Business -- Markets and Customers."

  Risks Relating to Fluctuations in Quarterly Operating Results

     The Company's quarterly operating results have varied and may continue to
fluctuate significantly from period to period, including on a quarterly basis.
At times in the past, the Company's net sales and net income have decreased from
the prior quarter. Operating results are affected by a number of factors,
including the timing and volume of orders and shipments relative to the
Company's manufacturing capacity, product and price competition, product mix,
number of working days in a particular quarter, manufacturing process yields,
the timing of expenditures in anticipation of future sales, timing of customer
requests for delivery from consignment stocks, raw material and component
availability, the length of sales cycles, trends in the electronics industry and
general economic factors. In recent years, the Company's gross margins have
varied primarily as a result of pricing, capacity utilization, product mix, lead
times, volume levels and complexity of customer orders. There can be no
assurance that the Company will be able to manage the utilization of
manufacturing capacity or product mix in a manner that will maintain or improve
gross margins. The Company's expense levels are relatively fixed and are based,
in part, on expectations of future revenues. Consequently, if revenue levels are
below expectations, this occurrence is likely to materially adversely affect the
Company's business, financial condition and results of operations. See Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

  Risks Relating to Variability of Orders from Customers; Backlog

     The level and timing of orders placed by the Company's customers vary due
to a number of factors, including customer attempts to manage inventory, changes
in the customers' manufacturing strategies and variations in demand for customer
products due to, among other things, technological changes, new product
introductions, product life-cycles, competitive conditions or general economic
conditions. Since the Company generally does not obtain long-term purchase
orders or commitments from its customers, it must anticipate the future volume
of orders based on discussions with its customers. A substantial portion of
sales in a given quarter may depend on obtaining orders for products to be
manufactured and shipped in the same quarter in which those orders are received.
The Company relies on its estimate of anticipated future volumes when making
commitments regarding the level of business that it will seek and accept, the
mix of products that it intends to manufacture, the timing of production
schedules and the levels and utilization of personnel and other resources. A
variety of conditions, both specific to the individual customer and generally
affecting the customer's industry, may cause customers to cancel, reduce or
delay orders that were previously made or anticipated. A significant portion of
the Company's sales are currently made through consignment stocking programs
which afford the Company's customers greater flexibility on timing of delivery
of product. The Company may experience sudden drops in shipment of product from
consignment stock and a corresponding decline in current revenues. A significant
portion of the Company's released backlog at any time may be subject to
cancellation or postponement without penalty. The Company cannot assure the
timely replacement of canceled, delayed or reduced orders. Significant or
numerous cancellations, reductions or delays in deliveries from consignment
stocks or in orders by a customer or group of customers could materially
adversely affect the Company's business, financial condition and results of
operations. See Item 7, "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Item 1, "Business -- Released Backlog."

  Competition

     The electronic interconnect industry is highly fragmented and characterized
by intense competition. The Company believes its major competitors are the large
U.S. and international independent producers that manufacture multilayer printed
circuits and provide backplane and other electronic system assemblies. Some of
these competitors have significantly greater financial, technical and marketing
resources, greater name

                                       19
<PAGE>   21

recognition and a larger installed customer base than the Company. 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 the Company.

     During periods of recession or economic slowdown in the electronics
industry and other periods when excess capacity exists, EMS providers and OEMs
are able to negotiate lower prices, which could have a material adverse effect
on the Company. In addition, the Company believes that price competition from
printed circuit manufacturers in Asia and other locations with lower production
costs plays a significant role in the printed circuit markets in which the
Company competes. The price competition from Asian printed circuit manufacturers
may intensify from time to time as a result of economic turmoil, currency
devaluations or financial market instability in Asian economies. Moreover the
Company's basic interconnect technology is generally not subject to significant
proprietary protection, and companies with significant resources or
international operations may enter the market. Increased competition could
result in price reductions, reduced margins or loss of market share, any of
which could materially adversely affect the Company's business, financial
condition and results of operations.

     The demand for printed circuits has continued to be affected by the
development of smaller, more powerful electronic components requiring less
printed circuit area. Expansion of the Company's existing products or services
could expose the Company to new competition. Moreover, new developments in the
electronics industry could render existing technology obsolete or less
competitive and could potentially introduce new competition into the industry.
There can be no assurance that the Company will continue to compete successfully
against present and future competitors or that competitive pressures faced by
the Company will not have a material adverse effect on the Company's business,
financial condition and results of operations. See Item 1, "Business --
Competition."

  Risks Relating to the Acquisitions and the Company's Acquisition Strategy

     The Company has limited experience in integrating acquired companies or
technologies into its operations. Therefore, there can be no assurance that the
Company will operate its acquired businesses profitably in the future. The
Company expects that its gross profit margin may be lower in future fiscal
quarters than has historically been the case due, in part, to the Acquisitions.
Operating expenses associated with the acquired businesses may have a material
adverse effect on the Company's business, financial condition and results of
operations in the future. See Item 7, "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and Item 1,
"Business -- General."

     The Company may from time to time pursue the acquisition of other
companies, assets, products or technologies. The Company may incur additional
indebtedness and additional charges against earnings in connection with future
acquisitions. Acquisitions involve a number of operating risks that could
materially adversely affect the Company's operating results, including the
diversion of management's attention to assimilate the operations, products and
personnel of the acquired companies, the amortization of acquired intangible
assets, and the potential loss of key employees of the acquired companies.
Furthermore, acquisitions may involve businesses in which the Company lacks
experience. There can be no assurance that the Company will be able to manage
one or more acquisitions successfully, or that the Company will be able to
integrate the operations, products or personnel gained through any such
acquisitions without a material adverse effect on the Company's business,
financial condition and results of operations.

  Risks of Inability to Manage Significant Growth

     In recent years, the Company significantly expanded its operations,
including geographically, which placed, and will continue to place, significant
demands on the Company's management, operational, technical and financial
resources. The Acquisitions have intensified these demands. The Company expects
that expansion will require additional management personnel and the development
of further expertise by existing management and supervisory personnel, in order
to train, motivate and manage its employees. The Company's ability to manage
growth effectively, particularly given the increasing scope of its operations,
will require it to

                                       20
<PAGE>   22

continue to implement and improve its operational, financial and management
information systems. The Company's failure to effectively manage future growth
could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Factors That May Affect Future
Results -- Risks Relating to the Acquisitions and the Company's Acquisition
Strategy" and "Factors That May Affect Future Results -- Dependence on Key
Personnel."

  Risks Relating to Operation of Malaysian Facility and Asian Economic Turmoil

     Hadco Santa Clara completed construction of a volume manufacturing facility
for printed circuits in Malaysia in fiscal 1997. Hadco's management has limited
experience in operating foreign manufacturing facilities, and there can be no
assurance that the Company will operate the facility on a profitable basis.
International operations are also subject to a number of risks, including
unforeseen changes in regulatory requirements, exchange rates, tariffs and other
trade barriers, misappropriation of intellectual property, currency
fluctuations, and political and economic instability. In recent years, Malaysia
and other Asian countries have experienced economic turmoil and a significant
devaluation of their local currencies. There can be no assurance that this
period of Asian economic turmoil will not result in increased price competition,
reduced sales by the Company's customers in Asia with a concomitant reduction in
such customers' orders for the Company's products, restrictions on the transfer
of funds overseas, employee turnover, labor unrest, the reversal of current
policies encouraging foreign investment and trade, or other domestic Asian
economic problems that could materially adversely affect the Company's business,
financial condition and results of operations.

  Rapid Technological Change, Continuing Process Development and Potential
Process Disruption

     The market for the Company's products and services is characterized by
rapidly changing technology and continuing process development. The future
success of the Company's business will depend in large part upon its ability to
maintain and enhance its technological capabilities, develop and market products
and services that meet changing customer needs and successfully anticipate or
respond to technological changes, on a cost-effective and timely basis. 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 circuits required in electronic components. There can be
no assurance that the Company will effectively respond to the technological
requirements of the changing market. To the extent the Company determines that
new technologies and equipment are required to remain competitive, the
development, acquisition and implementation of such technologies and equipment
are likely to continue to require significant capital investment by the Company.
There can be no assurance that capital will be available for this purpose in the
future or that investments in new technologies will result in commercially
viable technological processes or that there will be commercial applications for
these technologies. Moreover, the Company's business involves highly complex
manufacturing processes that have in the past and could in the future be subject
to periodic failure or disruption. Process disruptions can result in delays in
certain product shipments, and there can be no assurance that failures or
disruptions will not occur in the future. In addition, the Company has a large
manufacturing facility in Santa Clara, California, an area of the United States
that is subject to significant natural disasters, including earthquakes, fires
and flooding. The loss of revenue and earnings to the Company from such a
technological change, process development or process disruption, as well as any
disruption of the Company's operations resulting from a natural disaster in
California or other locations where the Company has facilities could have a
material adverse effect on the Company's business, financial condition and
results of operations. See Item 1, "Business -- Products and Services" and Item
2, "Manufacturing and Facilities."

  Customer Concentration

     During the past several years, the Company's sales to a small number of its
customers have accounted for a significant percentage of the Company's annual
net sales. During fiscal 1997, 1998 and 1999, the Company's ten largest
customers accounted for approximately 47%, 51% and 56% of net sales,
respectively. In fiscal 1998 and 1999, Solectron accounted for approximately 17%
and 15% of the net sales of the Company. The

                                       21
<PAGE>   23

Company has one customer that accounted for approximately 13% and 11% of
consolidated accounts receivable at October 31, 1998 and October 30, 1999,
respectively. Another customer accounted for 10% of consolidated accounts
receivable at October 30, 1999. The Company generally does not obtain long-term
purchase orders or commitments from its customers, and the orders received by
the Company generally require delivery within 90 days. Given the Company's
strategy of developing long-term purchasing relationships with high growth
companies, the Company's dependence on a number of its most significant
customers may increase. There can be no assurance that the Company will be able
to identify, attract and retain customers with high growth rates or that the
customers that it does attract and retain will continue to grow. Although there
can be no assurance that the Company's principal customers will continue to
purchase products and services from the Company at current levels, the Company
expects to continue to depend upon its principal customers for a significant
portion of its net sales. The loss of or decrease in orders from one or more
major customers or the inability or refusal of such customer to pay for such
orders could have a material adverse effect on the Company's business, financial
condition and results of operations. See Item 1, "Business -- Markets and
Customers" and "Factors That May Affect Future Results -- Risks Relating to
Variability of Orders from Customers; Backlog."

  Manufacturing Capacity

     The Company believes its long-term competitive position depends in part on
its ability to increase manufacturing capacity. The Company may obtain such
additional capacity through acquisitions or expansion of its current facilities.
Either approach would require substantial additional capital, and there can be
no assurance that such capital will be available from cash generated by current
operations. Further, there can be no assurance that the Company will be able to
acquire sufficient capacity or successfully integrate and manage such additional
facilities. Although the Company has historically needed to increase its
manufacturing capacity, the Company believes that excess capacity may exist in
the printed circuit industry. In addition, growth rates in the electronics
industry as a whole have fluctuated historically. These factors could have a
material adverse effect on future orders and pricing. The Company's expansion of
its manufacturing capacity has significantly increased and will continue to
significantly increase its fixed costs, and the future profitability of the
Company will depend on its ability to utilize its 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 the Company's relationships with its customers and materially
adversely affect the Company's business, financial condition and results of
operations. See "Factors That May Affect Future Results -- Rapid Technological
Change, Continuing Process Development and Potential Process Disruption" and
Item 2, "Manufacturing and Facilities."

  Environmental Matters

     The Company is subject to a variety of local, state and federal
environmental laws and regulations relating to the storage, use, discharge and
disposal of chemicals, solid waste and other hazardous materials used during its
manufacturing process, as well as air quality regulations and restrictions on
water use. When violations of environmental laws occur, the Company can be held
liable for damages and the costs of remedial actions and can also be subject to
revocation of permits necessary to conduct its business. Any such revocations
could require the Company to cease or limit production at one or more of its
facilities, which could have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, the Company's
failure to comply with present and future regulations could restrict the
Company's ability to expand its facilities or could require the Company to
acquire costly equipment or to incur other significant expenses to comply with
environmental regulations.

     Environmental laws could become more stringent over time, imposing greater
compliance costs and increasing risks and penalties associated with violation.
The Company operates in several environmentally sensitive locations and is
subject to potentially conflicting and changing regulatory agendas of political,
business and environmental groups. Changes or restrictions on discharge limits,
emissions levels, permitting requirements or processes, or material storage or
handling might require a high level of unplanned capital investment and/or
relocation. There can be no assurance that compliance with new or existing
regulations will

                                       22
<PAGE>   24

not have a material adverse effect on the Company's business, financial
condition and results of operations. See Item 1, "Business -- Environmental
Matters," Item 3, "Legal Proceedings and Claims" and Note 9 of Notes to the
Company's Consolidated Financial Statements.

  Risks of Inability to Obtain Raw Materials and Components

     Although the Company does not have guaranteed sources of raw materials,
production services and components utilized in its operations, it does have
supply agreements with a limited number of key suppliers, and it routinely
purchases raw materials, services and components from several material
suppliers. Although alternative material and services suppliers are currently
available, a significant unplanned event at a major supplier could have a
material adverse effect on the Company's operations. The Company believes that
the potential exists for shortages of materials and services in the printed
circuit and electronic assembly industries, which could have a material adverse
effect on the Company's manufacturing operations and future unit costs. Product
changes and the overall demand for electronic interconnect products could
increase the industry's use of new laminate materials, multilayer blanks, laser
drilling, mechanical drilling, non-standard surface finishes, electronic
components and other materials and services, and therefore such materials and
services may not be readily available to the Company in the future. Electronic
components used by the Company in producing backplane and system assemblies are
purchased by the Company and, in certain circumstances, the Company may bear the
risk of component price fluctuations. There can be no assurance that shortages
of certain types of electronic components will not occur in the future.
Component shortages or price fluctuations could have a material adverse effect
on the Company's backplane and system assembly business, thereby materially
adversely affecting the Company's business, financial condition and results of
operations. See Item 1, "Business -- Supplier Relationships."

  Dependence on Key Personnel

     The Company's future success depends to a large extent upon the continued
services of key managerial and technical employees. Most of the executive
officers of the Company are bound by employment or non-compete agreements. The
non-compete restrictions expire one year or, under certain circumstances, up to
two years, after the termination of the executive officer's employment with the
Company. Certain other key employees of the Company also have employment or
non-compete agreements. The loss of the services of any of the Company's key
employees could have a material adverse effect on the Company. The Company
believes that its future success depends on its continuing ability to attract
and retain highly qualified technical, managerial and marketing personnel.
Competition for such personnel is intense, especially for engineering personnel,
and there can be no assurance that the Company will be able to attract,
assimilate or retain such personnel. If the Company is unable to hire and retain
key personnel, the Company's business, financial condition and results of
operations may be materially adversely affected.

  Investments in Intellectual Property; Intellectual Property Protection

     The Company's success depends in part on its proprietary techniques and
manufacturing expertise, particularly in the area of dense multilayer printed
circuits. As of October 30, 1999, the Company had capitalized approximately
$179.3 million of acquired intangible assets, consisting primarily of developed
technology, customer relationships and goodwill. These intangible assets are
being amortized over lives ranging from 12 to 30 years. The Company assesses the
realizability and valuation of intangible assets based on the estimated cash
flows to be generated by such assets. Based on its most recent analyses, the
Company believes that no material impairment of intangible assets exists as of
October 30, 1999. Impairment occurs when actual cash flows generated do not
equal or exceed estimated cash flows. The estimated cash flows are based on
assumptions the Company believes to be reasonable, but which are inherently
uncertain and unpredictable. The Company's assumptions may be incomplete or
inaccurate, and no assurance can be given that unanticipated events and
circumstances will not occur. Accordingly, actual cash flows may vary from the
projected cash flows. In such event, the Company may be required to write-off or
write-down the value of assets which are impaired. Any such write-off or
write-down may result in a material adverse effect on the

                                       23
<PAGE>   25

financial condition and results of operations of the Company. See Notes 2 and 5
of Notes to the Company's Consolidated Financial Statements.

     The Company has few patents and relies primarily on trade secret protection
of its intellectual property. There can be no assurance that the Company will be
able to protect its trade secrets or that others will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's trade secrets. In addition, litigation may be
necessary to protect the Company's trade secrets, to determine the validity and
scope of the proprietary rights of others or to defend against claims of patent
infringement. If any infringement claim is asserted against the Company, the
Company may seek to obtain a license of the other party's intellectual property
rights. There is no assurance that a license would be available on reasonable
terms or at all. Litigation with respect to patents or other intellectual
property matters could result in substantial costs and diversion of management
and other resources and could have a material adverse effect on the Company's
business, financial condition and results of operations. See Item 1, "Business
Product Protection."

  Anti-Takeover Provisions

     The Company's Stockholder Rights Plan and certain provisions of the
Company's Restated Articles of Organization and By-Laws and of Massachusetts
Law, including Massachusetts General Laws Chapter 110D, entitled "Regulation of
Control Share Acquisitions" and Chapter 110F, the so-called Business Combination
Statute, could discourage potential acquisition proposals and could delay or
prevent a change in control or sale of the Company. Each and all of the above
provisions and statutes could diminish the opportunities for a stockholder to
participate in tender offers, including tender offers at a price above the then
current market value of Common Stock and may render more difficult or discourage
a merger, consolidation or tender offer (even if such transaction is supported
by the Company's Board of Directors or is favorable to the stockholders), the
assumption of control by a holder of a large block of the Company's shares, and
the removal of incumbent management.

ITEM 7A.  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
October 30, 1999. The fair market value of the Notes was $191 million with a
carrying amount of $199.4 million at October 30, 1999. 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 Credit Facility at
interest rates which are fixed for a maximum of six months. At October 30, 1999,
the Company's outstanding borrowings under the Credit Facility were $75.0
million, at a weighted average interest rate of 6.31%. This interest rate is a
combination of three Eurodollar rate loans. The interest rates on the three
Eurodollar rate loans will expire during the first quarter of fiscal 2000, at
which time the Company may fix these rates 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 office in Ireland, 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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Hadco Corporation:

     We have audited the accompanying consolidated balance sheets of Hadco
Corporation (a Massachusetts corporation) and subsidiaries as of October 31,
1998 and October 30, 1999, and the related consolidated statements of
operations, stockholders' investment and cash flows for each of the three years
in the period ended October 30, 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.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Hadco Corporation and
subsidiaries as of October 31, 1998 and October 30, 1999, and the results of
their operations and their cash flows for each of the three years in the period
ended October 30, 1999, in conformity with generally accepted accounting
principles.

     Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in item 14(a)(2) is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states, in all
material respects, the financial data required to be set forth therein, in
relation to the basic financial statements taken as a whole.

                       HADCO CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) OPERATIONS AND 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) 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 financial statements reflect the application of certain
accounting policies as described in this Note and elsewhere in the accompanying
notes to consolidated financial statements.

  Principles of Consolidation

     The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries. All significant intercompany
balances and transactions have been eliminated in consolidation.

  Management Estimates and Uncertainties

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

     The Company is subject to a number of risks and uncertainties similar to
those of other companies of the same size within the electronics industry,
including, without limitation, dependence on the electronics industry,
variability of customer orders, competition, rapid technological changes,
environmental matters and dependence on key individuals.

  Financial Instruments

     Statement of Financial Accounting Standards (SFAS) No. 107, Disclosures
About Fair Value of Financial Instruments, 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 October 30, 1999. The
fair market value of the Notes was $191 million with a carrying amount of $199.4
million at October 30, 1999. 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 prohibitive redemption premiums. See Note 8 of the Notes to the
Consolidated Financial Statements.

                       HADCO CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  Cash Equivalents

     The Company considers all highly liquid investment instruments purchased
with a maturity of three months or less to be cash equivalents. Cash equivalents
consist primarily of investments in money market funds and were approximately
$5,850,000 and $5,881,000 as of October 31, 1998 and October 30, 1999,
respectively.

  Concentration of Credit Risk

     SFAS No. 105, Disclosure of Information About Financial Instruments with
Off-Balance-Sheet Risk and Financial Instruments with Concentrations of Credit
Risk, requires disclosure of any significant off-balance-sheet and credit risk
concentrations. As of October 30, 1999, the Company had no significant
off-balance-sheet concentrations of credit risk such as foreign currency
exchange contracts or other hedging arrangements. Financial instruments that
subject the Company to credit risk consist of cash and cash equivalents, trade
accounts receivable and long-term debt obligations. The Company maintains the
majority of its cash and cash equivalent balances with financial institutions.
The Company has not experienced any losses on these investments to date.
Substantially all of the Company's accounts receivable are concentrated in the
high technology and electronics industry. The Company has not experienced
significant recurring losses related to receivables from individual customers or
groups of customers in the high technology and electronics industry or by
geographic region, although the Company has and may in the future incur a
significant loss in a particular reporting period. Due to these factors, no
additional credit risk beyond amounts provided for is believed by management to
be inherent in the Company's accounts receivable.

  Depreciation and Amortization of Property, Plant and Equipment

     The Company provides for depreciation and amortization on a straight-line
basis over the following estimated useful lives:

  Revenue Recognition

     The Company recognizes revenue at the time products are shipped.

  Research and Development Expenses

     The Company charges research and development expenses to operations as
incurred. For the fiscal years ended October 1997, 1998 and 1999, research and
development expenses were approximately $6,929,000, $6,111,000 and $5,924,000,
respectively, and are included in operating expenses.

  Net Income (Loss) per Share

     The Company applies SFAS No. 128, Earnings per Share.  Under SFAS No. 128,
basic net income (loss) per common share is computed based on net income (loss)
available to common stockholders and the weighted average number of common
shares outstanding during the period. The diluted net income (loss) per

                                       32

share is computed including the number of additional common shares that would
have been outstanding if the dilutive potential common shares had been issued.

     A reconciliation of basic and diluted shares outstanding is as follows:

</TABLE>

     Diluted weighted average shares outstanding does not include 1,070,000,
1,308,000 and 655,000 common equivalent shares at October 25, 1997, October 31,
1998 and October 30, 1999, respectively, as their effect would be anti-dilutive.

  Stock-Based Compensation

     The Company applies SFAS No. 123, Accounting for Stock-Based Compensation.
SFAS No. 123 defines a fair-value-based method of accounting for employee stock
options and other stock-based compensation. The compensation expense arising
from this method of accounting can be reflected in the financial statements or,
alternatively, the pro forma net income (loss) and per share amounts effect of
the fair-value-based accounting can be disclosed in the financial footnotes. The
Company has adopted the disclosure-only alternative. (See Note 10,
"Stockholders' Investment.")

  Foreign Currency Translation

     The financial statements of the Company's Malaysian and Irish subsidiaries
are translated in accordance with SFAS No. 52, Foreign Currency Translation. The
functional currency of the Company's Malaysian and Irish subsidiaries is the
U.S. dollar. Accordingly, all assets and liabilities of the foreign subsidiaries
are translated using the exchange rate at the balance sheet date, except for
prepaid expenses, equipment and improvements and stockholders' investment, which
are translated at historical rates. Revenues and expenses are translated at
historical rates. Translation gains and losses arising from the translations
were not material to the financial statements taken as a whole. These gains and
losses are included in the consolidated statements of operations, since the
functional currency is the U.S. dollar for all operations.

  Reclassification

     The Company has reclassified certain prior year information to conform with
the current year's presentation.

  Comprehensive Income (Loss)

     As of November 1, 1998, Hadco adopted SFAS No. 130, Reporting Comprehensive
Income. This Statement established standards for reporting and display of
comprehensive income (loss) and its components (revenues, expenses, gains and
losses) in a full set of general-purpose financial statements. Comprehensive
income (loss) is defined as the change in equity of a business enterprise during
a period from transactions and other events and circumstances from non-owner
sources. Hadco's comprehensive income (loss) is equal to net income (loss) for
all periods presented.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

  New Accounting Standards

     In June 1999, the Financial Accounting Standards Board (FASB) issued SFAS
No. 137, Accounting for Derivative Instruments and Hedging Activities --
Deferral of the Effective Date of FASB Statement No. 133, which defers the
effective date of SFAS No. 133 to all fiscal quarters of all fiscal years
beginning after June 15, 2000. SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires entities to
recognize all derivatives as either assets or liabilities in the statement of
financial position and measure those instruments at fair value. The Company does
not anticipate the adoption of these Statements to have a material impact on its
financial position or results of operations.

(2) ACQUISITIONS

     On January 10, 1997 the Company acquired all of the outstanding common
stock of Zycon Corporation ("Zycon") (the "Zycon Acquisition"), and on March 20,
1998, the Company acquired all of the outstanding common stock of Continental
Circuits Corp. ("Continental") (the "Continental Acquisition," and together with
the Zycon Acquisition, the "Acquisitions"). These Acquisitions were financed by
the Company's unsecured senior revolving credit facility with a group of banks.
The Company borrowed approximately $215,000,000 upon consummation of the Zycon
Acquisition and approximately $220,000,000 upon consummation of the Continental
Acquisition. The Acquisitions were accounted for as purchases in accordance with
Accounting Principles Board Opinion (APB) No. 16 and accordingly, Zycon's and
Continental's operating results since the respective dates of acquisition are
included in the accompanying consolidated financial statements. In accordance
with APB Opinion No. 16, the Company allocated the purchase price of the
Acquisitions based on the fair value of the assets acquired and liabilities
assumed. Significant portions of the purchase price of both were identified in
independent appraisals, using proven valuation procedures and techniques, as
intangible assets. These intangible assets include approximately $78,000,000 and
$63,050,000 for Zycon and Continental, respectively, for acquired in-process
research and development ("in-process R&D") for projects that did not have
future alternative uses. This allocation represents the estimated fair value
based on risk-adjusted cash flows related to the in-process R&D projects. At the
date of each acquisition, the development of these projects had not yet reached
technological feasibility, and the R&D in progress had no alternative future
uses. Accordingly, these costs were expensed as of the respective acquisition
date.

     The aggregate purchase prices of $212,485,000 and $190,156,000, including
acquisition costs, for the Zycon Acquisition and Continental Acquisition,
respectively, were allocated as follows:

     The provision for income taxes in 1997 and 1998 is calculated on income
before provision for taxes without taking into account the write-off of acquired
in-process R&D. This write-off was $78.0 million and $63.0 million for 1997 and
1998, respectively. Income before the provision for income taxes excluding the
write-off would have been $69.2 million and $14.8 million for 1997 and 1998,
respectively.

     The tax effects of temporary differences that give rise to significant
portions of the current and long-term deferred tax asset and liability at
October 31, 1998 and October 30, 1999 are as follows:

(7) LINES OF CREDIT

     The Company's revolving line of credit with various banks is pursuant to an
Amended and Restated Revolving Credit Agreement, as amended (the "Credit
Facility"). The Credit Facility provides, among other things, for direct
borrowings for up to the lesser of $198,750,000 or the Borrowing Base, as
defined in the Credit Facility, and expires January 8, 2002. Interest on loans
outstanding under the Credit Facility is payable at the Company's option at
either (i) the Base Rate (as defined in the Credit Facility) or (ii) the
Eurodollar Rate, plus the Applicable Eurodollar Rate Margin (both as defined in
the Credit Facility). The Company is required to pay a quarterly commitment fee
ranging from .2% to .375% per annum, based on certain financial ratios of the
Company, of the unused commitment under the Credit Facility. The Company is also
required to pay a quarterly usage fee based on an Applicable Base Rate Usage Fee
Margin and an Applicable Eurodollar Rate Usage Fee Margin (both as defined in
the Credit Facility). At October 31, 1998 and October 30, 1999, borrowings of
$150,000,000 and $75,000,000, respectively, were outstanding under the Credit
Facility at weighted average interest rates of 6.58% and 6.31%, respectively.
Borrowing availability under the Credit Facility was up to a maximum amount of
$123,750,000 at October 30, 1999.

     The Credit Facility contains customary representations and warranties. The
Credit Facility also contains extensive affirmative and negative covenants,
including, among others, certain limits on the ability of the Company and its
subsidiaries to incur indebtedness, create liens, make investments, pay
dividends or other distributions, engage in mergers, consolidations,
acquisitions or dispositions, enter into sale and lease-back transactions, enter
into guarantees, prepay subordinated indebtedness, create any new series of
capital stock or amend the terms of existing capital stock. The Credit Facility
also requires the Company to maintain certain financial covenants, including
maximum ratio of Consolidated Funded Debt to EBITDA, minimum interest coverage,
minimum consolidated net worth and minimum fixed charge coverage. At October 30,
1999, the Company was in compliance with all loan covenants.

     The Company has a line of credit arrangement with a Malaysian bank
denominated in Malaysian ringgits and U.S. dollars for aggregate borrowings of
approximately $3.4 million for the purpose of acquiring land, facilities and
equipment for the Company's Malaysian subsidiary. The arrangement is renewable
annually. At October 30, 1999, there were no amounts outstanding under this
arrangement.

     On May 18, 1998, the Company sold $200 million aggregate principal amount
of its 9 1/2% Senior Subordinated Notes due 2008 (the "Notes") to certain
purchasers. The purchasers subsequently resold the Notes to "qualified
institutional buyers" in reliance upon Rule 144A under the Securities Act of
1933, as amended (the "Securities Act"), and offshore purchasers pursuant to
Rule 904 of Regulation S under the Securities Act. The Notes were sold at a
price equal to 99.66% of their principal amount.

     On November 12, 1998, the Company consummated an exchange offer pursuant to
which the Notes were exchanged for Notes (with terms identical in all material
respects) that were registered with the Securities and Exchange Commission under
a registration statement on Form S-4.

     Interest on the Notes is payable semi-annually on each June 15 and December
15 and commenced December 15, 1998. The Notes are redeemable at the option of
the Company, in whole or in part, at any time on or after June 15, 2003, at
104.75% of their principal amount, plus accrued interest, with such percentages
declining ratably to 100% of their principal amount, plus accrued interest. At
any time on or prior to June 15, 2001 and subject to certain conditions, up to
35% of the aggregate principal amount of the Notes may be redeemed, at the
option of the Company, with the proceeds of certain equity offerings of the
Company at 109.50% of the principal amount thereof, plus accrued interest. In
addition, at any time prior to June 15, 2003, the Company may redeem the Notes,
at its option, in whole or in part, at a price equal to the principal amount
thereof, together with accrued interest, plus the Applicable Premium (as defined
in the Indenture governing the Notes).

     The Notes are guaranteed, on a senior subordinated basis, by each of the
Company's U.S. Restricted Subsidiaries (as defined in the Indenture) (the
"Guarantors"). The net proceeds received by the Company

from the issuance and sale of the Notes, approximately $193.8 million, were used
to repay outstanding indebtedness under the Credit Facility previously incurred
to, among other things, finance the Acquisitions.

     The Indenture under which the Notes were issued (the "Indenture") imposes
certain limitations on the ability of the Company, its subsidiaries and, in
certain circumstances, the Guarantors, to, among other things, incur
indebtedness, pay dividends, prepay subordinated indebtedness, repurchase
capital stock, make investments, create liens, engage in transactions with
stockholders and affiliates, sell assets and engage in mergers and
consolidations.

     Total rental expense of approximately $6,628,000, $9,805,000 and $9,700,000
was incurred for the fiscal years ended October 1997, 1998 and 1999,
respectively.

  Environmental Matters

     During March 1995, the Company received a Record of Decision ("ROD") from
the New York State Department of Environmental Conservation ("NYSDEC"),
regarding soil and groundwater contamination at its Owego, New York facility.
Based on a Remedial Investigation and Feasibility Study ("RIFS") for apparent
on-site contamination at that facility and a Focused Feasibility Study ("FFS"),
each prepared by environmental consultants of the Company, the NYSDEC has
approved a remediation program of groundwater withdrawal and treatment and
iterative soil flushing. The Company has executed a Modification of the Order on
Consent to implement the approved ROD. Capital equipment for this remediation
has already been acquired by the Company, and future operation and maintenance
costs, which will be incurred and expended over the estimated life of the
program of the next 28 years, are estimated at between $40,000 and $100,000 per

                                       39

year. Beginning in the summer of 1998, NYSDEC took additional samples from a
wetland area near the Company's Owego facility. Analytical reports of earlier
sediment samples indicated the presence of certain inorganics. The new samples
showed elevated levels of certain metals, but NYSDEC has not made a
determination as to the potential source of such metals, the remedial action to
be taken, or the persons to undertake and/or pay for any remediation. There can
be no assurance that the Company and/or other third parties will not be required
to conduct additional investigations and remediation at that location, the costs
of which are currently indeterminable.

     The Company has commenced the operation of a groundwater extraction system
at its Derry, New Hampshire facility to address certain groundwater
contamination and migration control issues. It is not possible to make a
reliable estimate of the length of time remedial activity will have to be
performed. However, it is anticipated that the groundwater extraction system
will be operated for at least 30 years. There can be no assurance that the
Company will not be required to conduct additional investigations and
remediation relating to the Derry facility. The total costs of such groundwater
extraction system and of conducting any additional investigations and
remediation relating to the Derry facility are not fully determinable.

     The Company accrues estimated costs associated with known environmental
matters, when such costs can be reasonably estimated. The cost estimates
relating to future environmental clean-up are subject to numerous variables, the
effects of which can be difficult to measure, including the stage of the
environmental investigations, the nature of potential remedies, possible joint
and several liability, the magnitude of possible contamination, the difficulty
of determining future liability, the time over which remediation might occur,
and the possible effects of changing laws and regulations. The total reserve for
environmental matters currently identified by the Company amounted to $10.6
million at October 31, 1998 and $11.1 million at October 30, 1999. The current
portion of these costs amounted to approximately $1.4 million as of October 31,
1998 and $1.9 million at October 30, 1999, and is included in other accrued
expenses. The long-term portion of these costs amounted to approximately $9.2
million as of October 31, 1998 and October 30, 1999, and is reported under the
caption Other Long-Term Liabilities. Based on its assessment at the current
time, management estimates the cost of ultimate disposition of the known
environmental matters to range from approximately $7.0 million to $12.0 million,
and is expected to be spread over a number of years. Management believes the
ultimate disposition of the above known environmental matters will not have a
material adverse effect on 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.

     Included in operating expenses are charges for actual expenditures and
accruals, based on estimates, for environmental matters. During fiscal 1997,
1998 and 1999, the Company made, and charged to operating expenses, actual
payments of approximately $296,000, $92,000, and $260,000, respectively, for
environmental matters.

  Litigation

     The Company is one of 33 entities which have been named as potentially
responsible parties in a lawsuit pending in the federal district court of New
Hampshire concerning environmental conditions at the Auburn Road, Londonderry,
New Hampshire landfill site. Local, state and federal entities and certain other
parties to the litigation seek contribution for past costs, totaling
approximately $20 million, allegedly incurred to assess and remedy the Auburn
Road site. In December 1996, following publication and comment period, the U.S.
Environmental Protection Agency (EPA) amended the ROD to change the remedy at
the Auburn Road site from active groundwater remediation to future monitoring.
In June 1999, the Company entered into a Consent Decree with 30 of the
defendants and third-party defendants. The Consent Decree was approved by the
federal and state governments in December 1999, and lodged with the Court. The
Court must still approve the

                       HADCO CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Consent Decree. Under the terms of the Consent Decree, the Company is a cash-out
party and does not have responsibility for performance of ongoing remedial or
monitoring work at the site.

     From 1974 to 1980, the Company operated a printed circuit manufacturing
facility in Florida as a lessee. This property is the subject of a pending
lawsuit in the circuit court for Broward County, Florida (the "Florida Lawsuit")
and an investigation by the Florida Department of Environmental Protection
("FDEP"). In connection with the investigation, Hadco and others have
participated in alternative dispute resolution regarding the site with an
independent mediator. Mediation sessions began in 1992 and continued over the
next several years through May 1998. In June 1995, Hadco and Gould, Inc.,
another prior lessee of the site, were joined as third-party defendants in the
pending Florida lawsuit by a party who had previously been named as a defendant
when the Florida lawsuit was commenced in 1993 by the FDEP. As a result of the
mediation, a Settlement Agreement was entered into among Hadco, Gould and the
FDEP in March 1999. The third-party complaints against Hadco and Gould in the
pending Florida lawsuit were dismissed. The Settlement Agreement provides that
Hadco and Gould will undertake remedial action based on a Supplemental
Contamination Assessment Report and a later Feasibility Study, which has been
prepared by a consultant to Hadco and Gould and approved by the FDEP. The
estimated cost of the recommended source removal described in the Feasibility
Study is approximately $165,000, and for ongoing monitoring and remediation is
approximately $2.1 million. Actual remedial activities have not yet commenced,
but are expected to begin in the near future.

     In March 1993, the EPA notified Hadco Santa Clara of its potential
liability for maintenance and remediation costs in connection with a hazardous
waste disposal facility operated by Casmalia Resources, a California Limited
Partnership, in Santa Barbara County, California. The EPA identified Hadco Santa
Clara as one of the 65 generators that had disposed the greatest amounts of
materials at the site. Based on the total tonnage contributed by all generators,
Hadco Santa Clara's share is estimated at approximately 0.2% of the total
weight.

     In June 1997, the United States District Court in Los Angeles, California
approved and entered a Consent Decree among the EPA and 49 entities (including
Hadco Santa Clara) acting through the Casmalia Steering Committee ("CSC"). The
Consent Decree sets forth the terms and conditions under which the CSC will
carry out work aimed at final closure of the site. Certain closure activities
will be performed by the CSC. Later work will be performed by the CSC, if funded
by other parties. Under the Consent Decree, the settling parties will work with
the EPA to pursue the non-settling parties to ensure they participate in
contributing to the closure and long-term operation and maintenance of the
facility.

     On January 12, 1998, Hadco Santa Clara received notice of the filing of a
lawsuit, before the Superior Court (County of Santa Clara, California), against
it by Jackie Riley, Keith Riley and Richard Riley for damages (including
punitive damages) for alleged injuries suffered, including Richard Riley's
cancer, as a result of the alleged emission at the Hadco Santa Clara facility of
effluent from allegedly toxic and hazardous chemical substances. In October
1999, the court approved a settlement of this litigation. The Company has
performed all its obligations under the settlement.

     The future costs in connection with the lawsuits described in the above
paragraphs are currently indeterminable due to such factors as the unknown
timing and extent of any future remedial actions which may be required, the
extent of any liability of the Company and of other potentially responsible
parties, and the financial resources of the other potentially responsible
parties. Management currently believes, based on the facts currently known to
it, that it is probable that the ultimate dispositions of the above lawsuits
will not have a material adverse effect on the Company's business and financial
condition; however, there can be no assurance that this will be the case.

  Purchase Commitments

     The Company had commitments to purchase approximately $9.2 million of
manufacturing equipment and approximately $1.4 million of leasehold improvements
as of October 30, 1999. The majority of these commitments is expected to be
completed by the end of fiscal 2000.

(10) STOCKHOLDERS' INVESTMENT

  Employee Stock Options

     The Company has several stock option plans that provide for the granting of
stock options to employees. The plans are administered by the Compensation
Committee of the Board of Directors and generally provide for the granting of
options at fair market value at the date of grant. The options vest over various
periods not to exceed 10 years, and expire at various times not exceeding 10
years plus 90 days from the date of grant. Substantially all employee stock
options granted are nonqualified stock options. The discussion below does not
include the plans pursuant to which the Board of Directors has determined not to
make future grants of options.

  December 1991 Director Plan

     This plan provides for the granting of options to purchase up to 300,000
shares of common stock at a price equal to the fair market value at the date of
grant. Initial options granted under this plan are exercisable ratably over a
four year period and expire no later than seven years from the date of grant.
This plan also provides for an annual grant of a vested option for 3,000 shares
to each non-employee director who has served as a director for five years or
more.

  November 1995 Plan

     This plan provides for the granting of options to purchase up to 1,000,000
shares of common stock at a price equal to fair market value at the date of
grant. The options vest according to each option agreement and they expire no
later than 10 years from the date of grant.

  The 1998 Stock Plan

     This plan provides for the granting of stock rights including options,
awards, and purchases up to 1,000,000 shares of common stock at a minimum price
equal to the fair market value at the date of grant. Stock rights may be granted
to employees, directors, and other associated parties. Stock rights will expire
as specified by the Compensation Committee, but in no case longer than 10 years
from the date of grant. The Company made awards of 9,085 shares under this plan
in fiscal 1999.

  Outside Directors Compensation Plan of 1998

     The Company adopted the Outside Directors Compensation Plan of 1998 (the
"Directors Plan") in December 1997. The Directors Plan provides that the annual
fee for the outside directors shall be paid in restricted stock, and that
additional meeting fees may, at the option of the director, be paid in
restricted stock. A total of 12,000 shares of common stock have been reserved
for grant under the Directors Plan (as reduced by the Board of Directors from
24,000 shares). The Company issued 4,436 and 3,741 shares in fiscal 1998 and
1999, respectively, under the Directors Plan. Subject to the approval of the
Outside Directors Compensation Plan of 2000 by the stockholders of the Company,
the Board of Directors determined not to make future grants of shares under the
Outside Directors Compensation Plan of 1998.

"Directors Plan of 2000') in December 1999 subject to stockholder approval. The
Directors Plan of 2000 provides that the annual fee for the outside directors
shall be paid in restricted stock, and that additional fees may, at the option
of a director, be paid in restricted stock. A total of 50,000 shares of common
stock have been reserved for grant under the Directors Plan of 2000, and no
shares have been issued to date.

  Employee Stock Purchase Plan

     The Employee Stock Purchase Plan (the ESP Plan) was approved by the
stockholders in March 1998 to allow eligible employees, as defined in the ESP
Plan, to purchase shares of common stock during one or more six-month periods
through payroll deductions. Shares are purchased at 85% of fair value, as
defined. A total of 500,000 shares of common stock have been reserved for
purchase under the ESP Plan. During fiscal 1998 and 1999, the Company issued
57,226 and 135,630 shares, respectively, under the ESP Plan. At October 30,
1999, the Company has 307,144 shares available for purchase under the ESP Plan.

  Stockholder Rights Plan

     The Company adopted a Stockholder Rights Plan in August 1995 pursuant to
which the Company declared the distribution of one Common Stock Purchase Right
("Right") for each share of outstanding common stock. Under certain conditions,
each Right may be exercised for one share of common stock at an exercise price
of $130, subject to adjustment. Under circumstances defined in the Stockholder
Rights Plan, the Rights entitle holders to purchase stock having a value of
twice the exercise price of the Rights. Until they become exercisable, the
Rights are not transferable apart from the common stock. The Rights may be
redeemed by the Company at any time prior to the occurrence of certain events at
$.01 per Right. The Stockholder Rights Plan will expire on September 11, 2005,
unless the Rights are earlier redeemed by the Company.

(14) BUSINESS SEGMENTS AND GEOGRAPHIC AREAS

     During the fourth quarter of fiscal 1999, the Company adopted 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). See Note 1 for a
description of the products and services provided by these segments.

     The accounting policies of the segments are the same as those described in
the summary of significant accounting policies described in Note 1. 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 function. 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 the Acquisitions. Management does not
represent that these segments, if operated independently, would report the
operating income and other financial information shown.

(15) RESTRUCTURING AND OTHER NON-RECURRING CHARGES

     On April 6, 1998, the Company announced the planned consolidation of its
two East Coast quick-turn prototype facilities into the larger of the two
facilities located at Haverhill, MA. The Company incurred and recorded in the
fiscal quarter ended May 2, 1998 non-recurring charges in connection with the
consolidation totaling $5.9 million. Non-recurring costs include costs
associated with the abandonment of assets at one of the facilities. On July 31,
1998, the Company announced a limited restructuring, which temporarily reduced
the Company's workforce by approximately 3%. This restructuring was in addition
to the consolidation of the East Coast quick-turn prototype facilities. The cost
of this limited restructuring is comprised of severance and related benefits for
the terminated employees. As of October 31, 1998 the Company had recorded a
liability

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

for both restructurings totaling $897,000, which relates to severance and other
payroll related costs, as well as lease termination costs. As of October 30,
1999, all amounts accrued for each restructuring had been paid. The component of
the charges classified as restructuring-related met the criteria set forth in
Emerging Issues and Task Force Issue ("EITF") 94-3, "Liability Recognition for
Certain Employee Termination Benefits and Other Costs to Exit an Activity
(including Certain Costs Incurred in a Restructuring)."

     The components of the restructuring and other non-recurring costs during
the year ended October 31, 1998 are as follows:

     Included in the restructuring and other charges is $2.5 million, which
represents the write-down of existing assets to their net realizable value, in
accordance with SFAS 121, Accounting for the Impairment of Long-Lived Assets and
Long-Lived Assets to be Disposed Of.

(16) SALE OF ASSETS

     On April 30, 1999, the Company sold substantially all of the assets of its
Dynaflex division for approximately $2.7 million. Dynaflex's assets, liabilities
and operations were not significant to the Company. Proceeds from the sale were
received on May 3, 1999.

(17) SUPPLEMENTAL GUARANTORS CONSOLIDATING CONDENSED FINANCIAL STATEMENTS

     Basis of presentation.  In connection with the Continental Acquisition,
which was financed with approximately $184 million of borrowings from the Credit
Facility, the Company on May 18, 1998 sold $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 condensed
consolidating financial statements of the Guarantors are presented below and
should be read in connection with the Consolidated 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 condensed consolidating 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.

                              CONSULTING AGREEMENT

       AGREEMENT made as of this 17th day of June, 1999, by and between HADCO
CORPORATION (the "Company") and PATRICK SWEENEY ("Sweeney").

       WHEREAS, Sweeney has retired from his position as a member of the Board
of Directors of the Company; and

       WHEREAS, the Company is desirous of utilizing the services of Sweeney as
a consultant to the Company.

       NOW, THEREFORE, in consideration of the premises and other mutual
covenants contained herein, the receipt and legal sufficiency of which are
hereby acknowledged, Sweeney and the Company agree as follows:

       1.     CONSULTING ARRANGEMENT. Effective July 1, 1999 through December
31, 2000, Sweeney shall serve as a consultant to the Company.


       2.     COMPENSATION AS CONSULTANT. During the term of the consulting
arrangement, from July 1, 1999 through December 31, 2000, Sweeney shall be paid
at the rate of $36,000 per annum, payable in equal monthly installments of
$3,000 on or about the 15th of each month beginning on or about July 15, 1999.
Sweeney acknowledges that during the period of the consulting arrangement, he
shall be an independent contractor of the Company and not an employee and,
accordingly, Sweeney shall be solely responsible for payment of all federal and
state withholding taxes, FICA and Medicare taxes, and all other applicable
employment related fees, taxes or charges. Sweeney shall be entitled to and
shall receive no fringe benefits from the Company during the term of the
consulting arrangement, including without limitation, pension contributions,
401(k) contributions, health (medical, dental and vision) and disability
insurance, life insurance coverage, and the like.

       3.     DUTIES. Sweeney shall perform such duties and responsibilities as
may be reasonably requested of him by the President of the Company. Both parties
anticipate that such duties may include marketing and public relation services
for the Company, both domestically and internationally.

       4.     CONFIDENTIALITY OF COMPANY INFORMATION. Sweeney recognizes and
acknowledges that he has been and will be privy to confidential information
concerning the Company's business, including without limitation, financial data,
personnel data, computer programs, supplier lists, technology, processes,
methods, techniques, developments, inventions, improvements, apparatus,
products, policies, customer lists, research data, plans, know-how, and trade
secrets, as well as information relating to sales, costs, profits, organization,
customers, pricing and pricing methods and other general business operations,
which are valuable, special and unique assets of the Company,



<PAGE>   2


access to and knowledge of which have been essential to the performance of
Sweeney's duties at the Company (hereinafter collectively the "Confidential
Information"). Sweeney agrees that he will not, during the term of his
consulting relationship or thereafter at any time, disclose any of this
Confidential Information to any person, firm, corporation, association or other
entity, excepting the authorized employees and agents of the Company, nor make
use of such Confidential Information either during the term of his consulting
relationship or at any time thereafter, for any purpose other than incident to
his duties with the Company. Without limiting the generality of the foregoing,
Sweeney expressly agrees that such Confidential Information will not be used to
compete directly or indirectly with the Company.

              Sweeney agrees that all materials developed or existing at the
Company, all programs developed for customers or prospective customers, all
files, letters, memoranda, reports, records, data, specifications, customer
lists, proposals, contracts, computer programs or computer-generated data
(whether hard copy or machine-readable form) and other documentation are the
exclusive property of the Company. Sweeney agrees, during the term of his
consulting relationship with the Company, to keep and use such materials only in
connection with the performance of his duties with the Company. Sweeney agrees
to return all such materials and any copies thereof and all other tangible
property of the Company immediately upon termination of any specific consulting
project.

       5.     CONFIDENTIALITY OF CUSTOMER AND SUPPLIER INFORMATION. Sweeney
recognizes and acknowledges that certain confidential data of the Company's
customers and suppliers may be made available to or utilized by him in the
course of his consulting relationship with the Company. Sweeney further
acknowledges that the Company may, in certain cases, be subject to
non-disclosure or secrecy agreements with certain customers and suppliers.
Accordingly, Sweeney expressly agrees and warrants that he will not, during the
term of or in the course of his consulting relationship or at any time
thereafter, disclose any such confidential data of any customer or supplier to
others, excepting the authorized employees and agents of the Company, nor make
use of such confidential data either during the term of his consulting
relationship or at any time thereafter, for any purpose other than incident to
his duties with the Company. Sweeney further agrees to sign any and all
non-disclosure and confidentiality agreements reasonably required by the
Company's customers and suppliers and approved by the Company's senior
management.

              Sweeney agrees to return to the Company immediately upon the
termination of his consulting relationship any and all copies of all
confidential data with respect to the Company's customers or suppliers,
including without limitation, materials secured from the Company's customers or
suppliers, programs developed for customers or suppliers, all files, letters,
memoranda, reports, records, data, specifications, customer lists, proposals,
contracts, computer programs or computer-generated data (whether hard copy or
machine-readable form) and other documentation relating to the confidential
information, data or technology of the Company's customers or suppliers.

<PAGE>   3

       6.     NON-COMPETITION. During the term of this Agreement, Sweeney agrees
that he will not, without the Company's prior express written consent, engage
in, have an interest in, be employed by, or be in any way, directly or
indirectly, connected with as an individual proprietor, partner, stockholder,
officer, employee, director, representative, agent, joint venturer, investor,
lender, or in any other employment, consulting or ownership capacity whatsoever
(other than as the holder of not more than one [1%] percent of the total
outstanding stock of a publicly-held company) any business that is substantially
similar to or competitive with that in which the Company is engaged. Without
limiting the generality of the foregoing, the Company agrees that Sweeney may
serve on the board of the IPC, and that such service by itself will not violate
the non-competition provisions of this Agreement.

       7.     NON-SOLICITATION. During the term of this Agreement, Sweeney
agrees that he will not, directly or indirectly, (a) employ, retain or engage
any person or entity who has worked for or with the Company as an employee or
consultant during the term of Sweeney's employment or during the term of
Sweeney's consulting arrangement; (b) recruit, solicit or induce, or attempt to
recruit, solicit or induce, any employee or consultant of the Company to
terminate his, her or its employment or consultant relationship with the
Company; (c) solicit, divert or take away, or attempt to solicit, divert or take
away, the business or patronage of any of the customers or accounts, or
prospective customers or accounts, of the Company which were contacted,
solicited or served during the term of his consulting arrangement with the
Company; or (d) induce or attempt to induce any customer, vendor or account of
the Company to reduce its business with, or to cease its business with, the
Company.

       8.     REMEDIES. Both parties agree that the restrictions contained in
Sections 4, 5, 6 and 7 are necessary for the protection of the business and
goodwill of the Company, and they are considered by Sweeney to be reasonable for
such purposes. Sweeney agrees that, in the event of a breach or threatened
breach by him of the provisions of Sections 4, 5, 6 or 7, the Company will
suffer irreparable harm which cannot be adequately compensated by a payment of
money damages. Accordingly, Sweeney agrees that, in the event of such a breach
or threatened breach by him, the Company shall be entitled to injunctive relief,
both preliminarily and permanently, and to specific enforcement of the
provisions of Sections 4, 5, 6 and 7. Nothing contained in this section shall be
construed as prohibiting the Company from pursuing any other remedies available
to it for such breach or threatened breach, including recovery of monetary
damages from Sweeney or others.

              Sweeney agrees, in addition to and not in lieu of any other
remedies the Company may have, that in the event he violates any of the
provisions of Sections 4, 5, 6 and 7, he shall forfeit entitlement to any
consulting fee not already paid.

       9.     SEVERABILITY. If any restriction set forth in Sections 4, 5, 6 or
7 are found by any court of competent jurisdiction to be unenforceable because

         Documents or in any document or instrument delivered pursuant to or in
         connection with the Credit Agreement, the other Loan Documents or this
         Amendment was true as of the date as of which it was made and is true
         as of the Effective Date (except to the extent of changes resulting
         from transactions contemplated or permitted by the Credit Agreement, as
         amended hereby, and the other Loan Documents and changes occurring in
         the ordinary course of business that singly or in the aggregate are not
         materially adverse and to the extent that such representations and
         warranties relate expressly to an earlier date), and no Default or

         Guarantors contained herein, in the Credit Agreement as herein amended,
         or in the other Loan Documents respectively, constitute the legal,
         valid and binding obligations of the Borrower and each of the
         Guarantors party hereto or thereto, enforceable against the Borrower or
         such Guarantor, in accordance with their respective terms, except as
         enforceability is limited by bankruptcy, insolvency, reorganization,
         moratorium or other laws relating to or affecting generally the

         availability of the remedy of specific performance or injunctive relief
         is subject to the discretion of the court before which any proceeding
         therefor may be brought.

         SS.7. RATIFICATION, ETC. Except as expressly amended hereby, the Credit
Agreement, the other Loan Documents and all documents, instruments and
agreements related thereto are hereby ratified and confirmed in all respects and

related agreement or instrument to the Credit Agreement or such other Loan
Documents shall hereafter refer to such agreements as amended hereby, pursuant
to the provisions of the Credit Agreement.

         SS.8. NO PRESENT CLAIMS. In order to eliminate any possibility that any

nor any of the other Transaction Parties has any claim or cause of action
against the Agent, any of the Banks or any of their directors, officers,
employees or agents; (ii) neither it nor any of the other Transaction Parties
has any offset right, counterclaim or defense of any kind against any of its
obligations, indebtedness or liabilities to the Agent and/or the Banks,
including, without limitation, the Obligations; and (iii) each of the Agent and
the Banks has heretofore properly performed and satisfied in a timely manner all
of its obligations to each of the Borrower and the other Transaction Parties.

         SS.9. EXPENSES. Without limiting the expense reimbursement requirements
set forth in ss.16 of the Credit Agreement, the Borrower agrees to pay on demand
all costs and expenses, including reasonable attorneys' fees, of the Agent
incurred in connection with this Amendment.

terms. Neither the Agent nor any of the Banks shall have any obligation to issue
any further waiver or consent with respect to the subject matter hereof or any
other matter.

         SS.11. COUNTERPARTS. This Amendment may be executed in one or more
counterparts, each of which shall be deemed an original but which together shall
constitute one and the same instrument.

         SS.12. GOVERNING LAW. THIS AMENDMENT SHALL FOR ALL PURPOSES BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF
MASSACHUSETTS (WITHOUT REFERENCE TO CHOICE OR CONFLICTS OF LAWS).

         for any Plan Year if it is included in a group of plans which are
         aggregated in accordance with the preceding sentence and the sum of (x)
         the present value of the cumulative accrued benefits for Key Employees
         under all defined benefit plans included in such aggregation group and

                  cumulative accrued benefit for any Employee or the amount of
                  the account of any Employee, such present value or amount
                  shall be increased by the aggregate distributions made with
                  respect to such Employee during the five (5) year period
                  ending on the Determination Date.

         (b)      Except to the extent provided in regulations issued by the
                  Secretary of the Treasury or his designate, any Rollover

                  shall not be taken account with respect to the transferee plan
                  for purposes of determining whether such plan is a Top Heavy
                  Plan (or whether any aggregation group which includes such

                  plan for any Plan Year, but such individual was a Key Employee
                  with respect to such plan for any prior Plan Year, any accrued
                  benefit for such Employee and the account of such Employee
                  shall not be taken into account.

         (d)      If an individual has not received any Compensation from the
                  Employer (other than benefits under the Plan) at any time
                  during the five (5) year period ending on the determination
                  date, any accrued benefit for such individual and the account
                  of such individual shall not be taken into account. (1/l/85)

         (e)      To the extent provided in regulations issued by the Secretary
                  of the Treasury or his designate, this section shall be
                  applied on the basis of any year specified in such regulations

         vesting purposes. An Employee who completes more than 1,000 hours of
         service during both twelve month periods extending from October 28,
         1979 to October 25, 1980 and from January 1, 1980 to December 3 1, 1980
         shall be credited with two Years of Service for purposes of determining
         his vested interest in his Profit Sharing Account. For purposes of
         crediting Years of Service under this Plan, an individual who becomes
         an Employee as a result of an asset or stock acquisition, merger or
         other similar transaction shall receive credit for service with his
         prior employer who was a party to such transaction. (10/28/79; 10/1/97)

                               PLAN PARTICIPATION

2.01     INITIAL PARTICIPATION

         For Plan Years ending on or before December 31, 1987, each Employee,
         other than an Employee who is covered by a collective bargaining
         agreement under which retirement benefits were the subject of good
         faith bargaining, shall commence participation hereunder on the first
         day of the month next following his completion of a Participation
         Computation Period during which he completed one thousand (1,000) Hours
         of Service, but in no event earlier than the Effective Date. For Plan
         Years beginning on or after January 1, 1988, each Employee, other than
         an Employee who is covered by a collective bargaining agreement under
         which retirement benefits were the subject of good faith bargaining,
         shall commence participation hereunder on the Entry Date next following
         the completion of a six month period of service with the Employer
         without regard to the number of Hours of Service completed. (1/l/88)

         For purposes of determining an Employee's initial eligibility to
         participate, an Employee shall receive credit for the time period
         commencing with the first day he performs an Hour of Service for the
         Employer and ending on the date a twelve consecutive month period of
         severance begins. A period of severance shall mean a period of time
         during which the Employee is no longer employed by the Employer, and
         shall begin on the earlier of (i) the date on which the Employee quits,
         retires, is discharged or dies or (ii) the first anniversary of the
         first day of a period in which the Employee remains absent from service
         (with or without pay) with the Employer for any reason other than quit,
         retirement, discharge or death, such as on account of vacation,
         holiday, sickness, disability, leave of absence or layoff; provided,
         however, that "second anniversary" shall be substituted for "first
         anniversary" under this clause (ii) for an Employee who is absent from
         service beyond the first anniversary of the first day of absence by
         reason of the pregnancy of the individual, the birth of a child of the
         individual, the placement of a child with the individual in connection
         with the adoption of such child by such individual, or for purposes of
         caring for such child for a period beginning immediately following such
         birth or placement.

         For purposes of determining eligibility to participate in this Plan, an
         individual who becomes an Employee as a result of an asset or stock
         acquisition, merger or other similar transaction shall receive credit
         for service with his prior employer who was a party to such
         transaction. (10/l/97)

         A Participant shall become an inactive Participant on the date his
         employment with the Employer terminates. He shall remain an inactive
         Participant until the date on which the balance of his Participant
         Account is distributed to him, or is forfeited, at which time he shall
         cease to be an inactive Participant and become a former Participant.

                          CONTRIBUTIONS AND ALLOCATIONS

3.01     PROFIT SHARING CONTRIBUTIONS

         The Employer may make annual Profit Sharing Contributions to the Trust
         in accordance with this Section 3.01 for the Fiscal Year during which
         this Plan is established and for each subsequent Fiscal Year. The
         Profit Sharing Contribution for each Fiscal Year shall be an amount
         from the Employer's current or accumulated Net Profit as determined
         annually by the Board of Directors of the Employer, subject to the
         limitations set forth in this Section 3.01 and in Section 3.09,
         provided that the Board of Directors may determine that no Profit
         Sharing Contribution shall be made for a particular Fiscal Year
         regardless of whether the Employer has a Net Profit for such year or an
         accumulated Net Profit for prior Fiscal Years.

         The Profit Sharing Contribution for each Fiscal Year shall be limited
         in amount so that it does not exceed any of the following amounts:

         (a)      The sum of the Employer's Net Profit for such Fiscal Year plus
                  its accumulated Net Profit for prior Fiscal Years; or

         (b)      The maximum amount deductible from the Employer's income for
                  such Fiscal Year under Section 404 of the Code as a
                  contribution to a profit sharing plan which meets the
                  requirements for qualification under Section 401 of the Code,
                  after taking into consideration all other Employer
                  contributions under this Plan; or

         (c)      The aggregate individual Participant limitations in accordance
                  with Section 415 of the Code, as applied in accordance with
                  Section 3.09.

         The Profit Sharing Contribution for each Fiscal Year shall be paid to
         the Trustee as soon as practicable after the end of the Fiscal Year,
         but in any event not later than the due date for the Employer's federal
         income tax return for such Fiscal Year, including extensions. If no
         Profit Sharing contribution is to be made for a particular Fiscal Year,
         the Employer shall so notify the Trustee within sixty (60) days after
         the end of such Fiscal Year. Profit Sharing Contributions shall be
         allocated to the Profit Sharing Accounts of those Participants who
         shall have received any 401(k) Compensation during such Fiscal Year and
         who are employed on the last day of the Fiscal Year. Such contribution
         shall be allocated according to the ratio that each such Participant's
         401(k) Compensation for the Fiscal Year bears to the total 401(k)
         Compensation of all such Participants for the Fiscal Year. For
         individuals who have become Participants during the 1997 Fiscal Year as
         a result of an asset or stock acquisition, merger or other similar
         transaction, the 401(k) Compensation to be taken into account hereunder
         for said Fiscal Year shall be 401(k) Compensation received during the
         period from January 1, 1997 through October 25, 1997 from the Employer
         or from the individual's prior employer who was a party to the
         transaction. For individuals who have become Participants during the
         1998 Fiscal Year


<PAGE>   18

                                      -14-

         as a result of an asset or stock acquisition, merger or other similar
         transaction, the 401(k) Compensation to be taken into account hereunder
         for said Fiscal Year shall be 401(k) Compensation received during the
         period from April 1, 1998 through October 31, 1998 from the Employer or
         from the individual's prior employer who was a party to the
         transaction.

         (1/1/88; 3/10/93; 1/1/97; 1/1/98)

3.02     401(k) CONTRIBUTIONS

         Effective as of April 1, 1988, an Employee who has met the eligibility
         and participation requirements of Article II may elect to defer not
         less than 1% nor more than 15% of his 401(k) Compensation pursuant to a
         salary reduction agreement with the Employer, in lieu of receiving cash
         compensation. Such deferred amounts shall be paid by the Employer to
         the Trustee as 401(k) Contributions promptly following each pay period
         and shall be allocated to the Participant's 401(k) Account. 401(k)
         Contributions may be made under this Section 3.02 without regard to
         current or accumulated Net Profits of the Employer.

         An initial election to authorize 401(k) Contributions must be effective
         as of an Entry Date following the date of the election. A Participant
         may change the amount of his 401(k) Contribution as of the beginning of
         any calendar quarter, or more frequently if administratively feasible,
         and may revoke any election to authorize 401(k) Contributions at any
         time. No such change or revocation may be retroactively effective. No
         Participant shall be required to make an election under this Section
         3.02.

         No Employee shall be permitted to have 401(k) Contributions made under
         this Plan during any calendar year in excess of $7,000.00 adjusted for
         cost of living changes determined by the Secretary of the Treasury
         under Section 402(g) of the Code. In addition, 401(k) Contributions on
         behalf of Highly Compensated Employees shall be limited as provided in
         Section 3.09. The provisions of Section 4.04 shall further limit the
         election and amount of 401(k) Contributions for any Participant who has
         received a hardship distribution pursuant to that Section.

         (1/l/88; 7/l/96)

3.03     MATCHING CONTRIBUTIONS

         The Employer shall make Matching Contributions to the Trust on behalf
         of each Participant for whom 401(k) Contributions have been made during
         the Plan Year, in accordance with this Section 3.03 and subject to the
         limits of Section 3.09.

         The amount of the Matching Contribution for Plan Years ending on or
         before December 31, 1996 shall be equal to 25% of the amount of the
         Participant's aggregate 401(k) Contributions for the Plan Year that do
         not exceed four (4%) percent of the Participant's aggregate 401(k)
         Compensation for the Plan Year.


<PAGE>   19

                                      -15-

         The amount of the Matching Contribution for the 1997 Plan Year shall be
         equal to the sum of (1) 25% of the amount of the Participant's
         aggregate 401(k) Contributions for the period from January 1, 1997
         through October 31, 1997 that do not exceed four (4%) percent of the
         Participant's aggregate 401(k) Compensation for such period, and (2)
         50% of the amount of the Participant's aggregate 401(k) Contributions
         for the period from November 1, 1997 through December 31, 1997 that do
         not exceed six (6%) percent of the Participant's aggregate 401(k)
         Compensation for such period.

         The amount of the Matching Contribution for Plan Years beginning on or
         after January 1, 1998 shall be equal to 50% of the amount of the
         Participant's aggregate 401(k). Contributions for the Plan Year that do
         not exceed six (6%) percent of the Participant's aggregate 401(k)
         Compensation for the Plan Year.

         The Employer's Matching Contribution for each Participant shall be
         recalculated monthly or more frequently based upon the Participant's
         year-to-date 401(k) Contributions and 401(k) Compensation. For the 1997
         Plan Year, any Participant who reached the maximum permitted 401(k)
         Contributions under Section 3.02 prior to the end of the Plan Year and
         who is employed on the last day of the Plan Year shall be treated as
         having made his 401(k) Contributions and having received his 401(k)
         Compensation in equal monthly amounts over the entire Plan Year.

         Matching Contributions under this Section 3.03 may be made without
         regard to current or accumulated Net Profits.

         Matching Contributions shall be paid by the Employer to the Trustees
         not later than the due date for the Employer's federal income tax
         return for the Fiscal Year which ends within the Plan Year, including
         extensions. Matching Contributions shall be allocated to the Matching
         Contributions Accounts of the respective Participants on whose behalf
         the contributions are made.

         (1/l/88; 1/l/94; 11/l/97)

3.04     QUALIFIED NON-ELECTIVE CONTRIBUTIONS

         The Employer may make Qualified Non-elective Contributions to the Trust
         in accordance with this Section 3.04 for any Plan Year. If a
         Participant authorizes 401(k) Contributions under Section 3.02 when he
         first becomes eligible to do so, the Employer shall contribute to the
         Trust on behalf of such Participant as a Qualified Non-elective
         Contribution the sum of $100.00 without regard to the amount of the
         401(k) Contribution. Any additional Qualified Non-elective Contribution
         for any Plan Year shall be an amount as determined annually by the
         Board of Directors of the Employer, subject to the limitations set
         forth in Section 3,.09, provided that the Board of Directors may
         determine that no Qualified Non-elective Contribution shall be made for
         a particular Plan Year, and provided further that the Board of
         Directors may authorize any additional Qualified Non-elective
         Contribution to be allocated among all Participants who are Non-highly
         Compensated Employees equally, or according to the ratio that each such
         Participant's 401(k) Contributions for the


<PAGE>   20

                                      -16-

         Plan Year bears to the total 401(k) Contributions of all Participants
         who are Non-highly Compensated Employees, or according to the ratio
         that each such Participant's Compensation bears to the total
         Compensation of all Participants who are Non-highly Compensated
         Employees for the Plan Year.

         Qualified Non-elective Contributions under this Section 3.04 may be
         made without regard to current or accumulated Net Profits.

         Qualified Non-elective Contributions shall be paid to the Trustee as
         soon as practicable after the end of the Plan Year, but in any event
         not later than the due date for the Employer's federal income tax
         return for the Fiscal Year which ends within such Plan Year, including
         extensions, shall be allocated to the 401(k) Accounts of Participants
         on whose behalf the contributions are made, and shall be fully vested
         when made.

         (1/l/88)

         For Plan Years ending on or before December 31, 1987, a Participant may
         elect to make After-Tax Contributions to the Trust by executing an
         application authorizing the Employer to make regular payroll deductions
         of said After-Tax Contributions or by means of a lump sum payment to
         the Trust. The amount of such After-Tax Contributions shall be subject
         to the limitations of Section 3.09, and the aggregate of all amounts a
         Participant contributes shall not exceed ten (10%) percent of the total
         Compensation paid to him since he became a Participant in the Plan.
         After-Tax Contributions shall be allocated to the After-Tax
         Contributions Account of the Participant who has made such
         contribution.

         (1/l/88)

3.06     ROLLOVER CONTRIBUTIONS

         An Employee may, with the consent of the Plan Administrator and the
         Trustee, contribute to the Trust a participant note for a plan loan or
         cash as a Rollover Contribution from another qualified plan or trust or
         an individual retirement account or annuity in accordance with Sections
         402(c)(4), 403(a)(4) or 408(d)(3) of the Code and the regulations
         thereunder. A participant note for a plan loan must be assigned to the
         Trust directly from the other qualified plan or trust. The Plan
         Administrator or Trustee shall maintain a separate Rollover Account
         under the Trust for each Employee who has made a Rollover Contribution.
         All such Rollover Contributions and the investments thereon shall
         immediately become and at all times remain fully vested in the
         Employee. Rollover contributions shall not be taken into consideration
         in determining the limitations set forth in Section 3.09. (1/l/88;

3.07     FORFEITURES

         Any Forfeitures from Profit Sharing Accounts which have become
         available for distribution during a Plan Year shall be credited to the
         Profit Sharing Accounts of those Participants who are entitled to share
         in the Employer's Profit Sharing Contribution for the Fiscal Year
         ending with or within such Plan Year (regardless of whether a Profit
         Sharing Contribution has been made) and such amounts shall be allocated
         in the same manner as the Employer's Profit Sharing Contribution under
         Section 3.01.

         Any Forfeitures from Matching Contributions Accounts which have arisen
         during a Plan Year shall be used to reduce the amount of Matching
         Contributions required to be made by the Employer under Section 3.03
         for the Plan Year. In the event that the amount of such Forfeitures
         exceeds the amount of Matching Contributions so required, the excess
         shall be held in a suspense account to be used to reduce the amount of
         Matching Contributions required for any subsequent Plan Year. In the
         event that upon the termination of the Plan there is any amount then
         held in such suspense account, such amount shall be allocated among
         those Participants who have a balance in their Matching Contributions
         Accounts according to the ratio that the aggregate of each such
         Participant's Matching Contributions Account and 401(k) Account bears
         to the aggregate of all Participants' Matching Contributions Accounts
         and 401(k) Accounts, and such amounts shall be credited to such
         Matching Contributions Accounts, subject to Sections 3.09 and 3.10.

3.08     INVESTMENT ADJUSTMENT

         Beginning as of July 1, 1996, the net earnings or losses of the trust
         fund shall be computed on a daily basis. Dividends and interest shall
         be credited as of the date they are declared, and gains and losses from
         investments shall be credited or debited at the time they are realized.

                  (ii)     for Plan Years ending on or before December 31, 1997,
                           25% of the Participant's Compensation for such Plan

                           Participant's 414(q) Compensation for such Plan Year.

                  For Plan Years ending on or before December 31, 1986, the term
                  "annual addition" shall mean the sum of (1) Employer
                  Contributions, plus (2) the lesser of one-half (1/2) of the
                  Participant's After-Tax Contributions or such Participant's
                  After-Tax Contributions in excess of six percent (6%) of his
                  annual Compensation, plus (3) Forfeitures. For Plan Years
                  beginning after December 31, 1986, the term "annual addition"
                  shall mean the amount allocated to a Participant's Account
                  during the Plan Year that constitutes Profit Sharing
                  Contributions, 401(k) Contributions, Matching Contributions,
                  Qualified Non-elective Contributions, After-Tax Contributions
                  and Forfeitures.

                  In the event the limits of this Section 3.09(a) are exceeded,
                  the provisions of Section 3.10(a) shall become effective.

                  (1/1/88; 1/1/98)

         (b)      Maximum 401(k) Contributions ("ADP Test")

                  The average actual deferral percentage for eligible
                  Participants who are Highly Compensated Employees for the Plan
                  Year shall not exceed the greater of (i) or (ii) below:

                  (i)      the average actual deferral percentage for eligible
                           Participants who are Non-highly Compensated Employees
                           for the Plan Year multiplied by 1.25, or

                  (ii)     the average actual deferral percentage for eligible
                           Participants who are Non-highly Compensated Employees
                           for the Plan Year multiplied by 2.0, provided that
                           the average actual deferral percentage for eligible
                           Participants who are Highly Compensated Employees
                           does not exceed the average actual deferral
                           percentage for eligible Participants who are
                           Non-highly Compensated Employees by more than two
                           percentage points or such lesser amount as the
                           Secretary of the Treasury may prescribe by
                           regulation, and provided further that the provisions
                           of Section 3.09(d) are not applicable.

                  For purposes of this Section 3.09(b) and Section 3.10(c), the
                  following definitions shall be used:

                  (x)      "Actual deferral percentage" shall mean the ratio
                           (expressed as a percentage and rounded to the nearest
                           one-hundredth of a percent) of 401(k) Contributions
                           and, to the extent needed to meet the requirements of
                           Section 401(k)(3)(A)(ii) of the Code, Qualified
                           Non-elective Contributions on behalf of the eligible
                           Participant for the Plan Year to the eligible
                           Participant's 414(q) Compensation for the Plan Year
                           and shall be

                           determined separately for each eligible Participant.
                           The actual deferral percentage of an eligible
                           Participant who does not elect to have 401(k)
                           Contributions made to his Account shall be zero.

                  (y)      "Average actual deferral percentage" shall mean the
                           average (expressed as a percentage and rounded to the
                           nearest one-hundredth of a percent) of the actual
                           deferral percentages of the eligible Participants in
                           a group.

                  (z)      "Eligible Participant" shall mean any Participant who
                           is eligible under the terms of the Plan to have
                           401(k) Contributions allocated to his Account for all
                           or any part of the Plan Year and includes an Employee
                           who would be a Participant but for his failure to
                           elect 401(k) Contributions, an Employee whose
                           eligibility to elect 401(k) Contributions has been
                           suspended because of an election not to participate
                           or because of a distribution or a loan, and an
                           Employee who cannot elect 401(k) Contributions
                           because the limitations on annual additions set out
                           in Section 3.09(a) above would be exceeded.

                  For purposes of calculating actual deferral percentages, a
                  401(k) Contribution shall be taken into account for the Plan
                  Year being tested only if the contribution (1) is allocated to
                  the Participant's Account as of a date within the Plan Year,
                  (2) is not contingent upon the Participant's participation in
                  the Plan or performance of services on any date subsequent to
                  that date, (3) is actually paid to the trust no later than the
                  end of the 12-month period immediately following the Plan Year
                  to which the contribution relates, and (4) relates to
                  compensation that, but for the Participant's election to
                  authorize the contribution, would have been received by him in
                  the Plan Year or within two and one-half months after the
                  close of the Plan Year. Qualified Non-elective Contributions
                  may be taken into account to the extent needed to meet the
                  requirements of Section 401(k)(3)(A)(ii) of the Code, as set
                  out in paragraphs (i) and (ii) above, in accordance with the
                  provisions of Treasury Reg. ss.1.401(k)-1 (b) which is
                  incorporated herein by reference.

                  For Plan Years ending on or before December 31, 1996, for
                  purposes of the ADP Tests under paragraphs (i) and (ii) above,
                  Employees who are Family Members of a five percent owner or a
                  Highly Compensated Employee who is one of the ten most highly
                  compensated Employees, ranked on the basis of 414(q).
                  Compensation paid by the Employer during such year, shall be
                  aggregated with the Highly Compensated Employee. Where family
                  aggregation is required, the related Employees are treated as
                  one Highly Compensated Employee and the actual deferral
                  percentage for the group is the ratio determined by combining
                  the 414(q) Compensation, 401(k) Contributions and Qualified
                  Non-elective Contributions of the Highly Compensated Employee
                  and all Family Members. Once the ratio for the group has been
                  determined, the 414(q) Compensation, 401(k) Contributions and
                  Qualified Non-elective Contributions of each Family Member are
                  not separately taken into account in the applicable test.

                  The determination and treatment of the 401(k) Contributions,
                  Qualified Non-elective Contributions and actual deferral
                  percentage of any Participant shall satisfy such other
                  requirements as may be prescribed under Treasury Reg.
                  ss.1.401(k)-1(b).

                  In the event the limits of this Section 3.09(b) are exceeded,

                           Participants who are Non-highly Compensated Employees
                           for the Plan Year multiplied by 1.25; or

                  (ii)     The average contribution percentage for eligible
                           Participants who are Non-highly Compensated Employees
                           for the Plan Year multiplied by 2.0, provided that
                           the average contribution percentage for eligible
                           Participants who are Highly Compensated Employees
                           does not exceed the average contribution percentage
                           for eligible Participants who are Non-highly
                           Compensated Employees by more than two percentage
                           points or such lesser amount as the Secretary of the
                           Treasury may prescribe by regulation, and provided
                           further that the provisions of Section 3.09(d) are
                           not applicable.

                  For purposes of this Section 3.09(c) and Section 3.10(d), the
                  following definitions shall be used:

                  (w)      "Average contribution percentage" shall mean the
                           average (expressed as a percentage and rounded to the
                           nearest one-hundredth of a percent) of the
                           contribution percentages of the eligible Participants
                           in a group.

                  (x)      "Contribution percentage" shall mean the ratio
                           (expressed as a percentage and rounded to the nearest
                           one-hundredth of a percent), of the sum of the
                           employee contributions and Matching Contributions
                           under the Plan on behalf of the eligible Participant
                           for the Plan Year to the eligible Participant's
                           414(q) Compensation for the Plan Year and shall be
                           determined separately for each eligible Participant.
                           The contribution percentage of an eligible
                           Participant who makes no employee contributions and

                  (y)      "Eligible Participant" shall mean any Participant who
                           is eligible under the terms of the Plan to have

                           part of the Plan Year and includes an Employee who
                           would be a Participant but for his failure to make
                           contributions under this or any other Plan, an
                           employee whose eligibility to make employee
                           contributions or to receive Matching Contributions

                           participate, and an Employee who cannot make employee
                           contributions or receive a Matching Contribution
                           because the limitations on annual additions set out
                           in Section 3.09(a) above would be exceeded.

                  (z)      "Employee Contributions" shall mean any mandatory or
                           voluntary contribution to the plan that is treated at
                           the time of contribution as an after-tax employee
                           contribution and is allocated to a separate account
                           to which earnings and losses are allocated and
                           includes After-Tax Contributions and amounts
                           attributable to Excess 401(k) Contributions as
                           defined in Section 3.10(c) that have been
                           recharacterized as contributed by the Participant to
                           the Trust. Employee contributions do not include
                           repayment of loans, repayment of distributions
                           described in Section 411(a)(7)(C) of the Code and
                           Section 7.03 of the Plan, and employee contributions
                           that are transferred to the Plan from another Plan.

                  For purposes of calculating actual contribution percentages,
                  an employee contribution shall be taken into account for the
                  Plan Year being tested only if the contribution is paid to the
                  trust during the Plan year or paid to an agent of the Plan
                  within the Plan Year and transmitted to the Trust within a
                  reasonable period after the end of the Plan Year. An Excess
                  401(k) Contribution that is re-characterized shall be taken
                  into account in the Plan Year in which the contribution would
                  have been received in cash by the Participant had he not
                  elected to defer the amount. A Matching Contribution shall be
                  taken into account for a Plan Year only if it (1) is made on
                  account of the Participant's elective or employee
                  contributions for the Plan year, (2) is allocated to the
                  Participant's Account as of a date within the Plan Year, and
                  (3) is actually paid to the trust no later than the end of the
                  12-month period immediately following the Plan Year to which
                  the contribution relates. A Matching Contribution that is
                  forfeited to correct Excess Aggregate Contributions, or
                  because the contribution to which it relates is treated as an
                  Excess Deferral under Section 3.10(b), an Excess 401(k)
                  Contribution under Section 3.10(c), or an Excess Aggregate
                  Contribution under Section 3.10(d) shall not be taken into
                  account for purposes of calculating actual contribution
                  percentages. Qualified Non-elective Contributions may be
                  treated as Matching Contributions and taken into account to
                  the extent needed to meet the requirements of Section 401(m)
                  (2)(A) of the Code, as set out in paragraphs (i) and (ii)
                  above, if and to the extent not used to meet the requirements
                  of Section 401(k)(3)(A)(ii) of the Code and if the
                  requirements of Treasury Reg. ss.1.401 (m)-1(b)(5) are
                  satisfied.

                  For Plan Years ending on or before December 31, 1996, for
                  purposes of the ACP Tests under paragraphs (i) and (ii) above,
                  Employees who are Family Members of a five percent owner or a
                  Highly Compensated Employee who is one of the ten

                  most highly compensated Employees shall be aggregated with the
                  Highly Compensated Employee. Where family aggregation is
                  required, the related Employees are treated as one Highly
                  Compensated Employee and the contribution percentage for the
                  group is the ratio determined by combining the 414(q)
                  Compensation, employee contributions and Matching
                  Contributions of the Highly Compensated Employee and all
                  Family Members. Once the ratio for the group has been
                  determined, the 414(q) Compensation, employee contributions
                  and Matching Contributions of each Family Member are not
                  separately taken into account in the applicable test. (1/l/97)

                  The determination and treatment of employee contributions,
                  Matching Contributions and Qualified Non-elective
                  Contributions and the contribution percentage of any eligible
                  Participant shall satisfy such other requirements as may be
                  prescribed under Treasury Reg. ss.1.401(m)(I)(b), which is
                  incorporated herein by reference.

                  In the event the limits of this Section 3.09(c) are exceeded,
                  the provisions of Section 3.10(d) shall become effective.

         (d)      Restrictions on Multiple Use of Alternative Limitation for ADP
                  and ACP Tests

                  The provisions of Sections 3.09(b)(ii) and 3.09(c)(ii) set
                  forth alternative methods of compliance with Sections 401(k)
                  and 401(m) of the Code, respectively, and are referred to in
                  this section as the "alternative limitation." Multiple use of
                  the alternative limitation under both Section 3.09(b) and
                  Section 3.09(c) is not permitted. A determination whether
                  multiple use of the alternative limitation has occurred shall
                  be made in accordance with Treasury Reg.
                  ss.1.401(m)-1(b).

                  In the event multiple use of the alternative limitation has
                  occurred with respect to a Plan Year, such multiple use shall
                  be corrected in accordance with this Section 3.09(d). The
                  Employer shall have the option of eliminating the multiple use
                  of the alternative limitation by making Qualified Non-elective
                  Contributions. If such Qualified Non-elective Contributions
                  are not made, or are made but do not eliminate the multiple
                  use of the alternative limitation, the actual contribution
                  percentage of the entire group of eligible Participants who
                  are Highly Compensated Employees shall be reduced so that
                  there is no multiple use of the alternative limitation. The
                  calculation of the amount of the reduction of the actual
                  contribution percentages shall be made in accordance with the
                  provisions of Treasury Reg. ss.1.401(m)-1(e)(2), which is
                  incorporated herein by reference.

         (e)      Limitations on Compensation

                  For Plan Years beginning after December 31, 1993, the
                  Compensation of each Employee taken into account under this
                  Plan shall not exceed $150,000.00,

                  adjusted for cost of living changes determined by the
                  Secretary of the Treasury under Section 401(a)(17)(B) of the
                  Code. For Plan Years beginning after December 31, 1988 and
                  before January 1, 1994, the Compensation of each Employee
                  taken into account under this Plan shall not exceed $200,000
                  adjusted for cost of living changes determined by the
                  Secretary of the Treasury under Section 401(a)(17) of the
                  Code. The Compensation of an Employee who is a five percent
                  owner or a Highly Compensated Employee who is one of the ten
                  most highly compensated employees ranked on the basis of
                  Compensation paid by the Employer during such year shall
                  include the Compensation of the spouse of the Employee and of
                  any lineal descendant of the Employee who has not attained age
                  19 before the end of the Plan Year, and such persons shall not
                  be considered separate Employees.

3.10     ALLOCATION OF EXCESS ALLOCATIONS AND CONTRIBUTIONS

         (a)      Excess Annual Additions

                  The following steps shall be taken when a Participant has
                  received an allocation to his Participant Account in a given
                  Plan Year which results in an annual addition that would
                  exceed the limitations in 3.09(a) above:

                  (i)      That portion of a Participant's After-Tax
                           Contribution for that Plan Year which is a part of
                           the annual additions shall be refunded to him to the
                           extent necessary to reduce the annual addition to the
                           allowable limits as set forth in Section 3.09(a)
                           above.

                  (ii)     If, after returning a Participant's After-Tax
                           Contributions for that Plan Year as called for in (i)
                           above, the limits of Section 3.09(a) are still
                           exceeded, then the excess portion of the allocation
                           of Profit Sharing Contributions and Forfeitures shall
                           be reallocated to eligible Participants as a
                           Forfeiture for the Year in the manner described in
                           Section 3.07 of this Article III.

                  (iii)    In the event that any Profit Sharing Contributions
                           and/or Forfeitures may still be remaining subsequent
                           to the procedures set forth in (ii) above, then such
                           amounts shall be placed in a suspense account to be
                           reallocated on the next succeeding Allocation Date in
                           accordance with Section 3.07 of this Article Ill. In
                           the event of termination of the Plan, the suspense
                           account shall revert to the Employer to the extent it
                           may not then be allocated to any Participant's
                           Account.

                  (iv)     Notwithstanding any other provisions of this Plan,
                           the Employer shall not contribute any amount that
                           would cause an allocation to the suspense account as
                           of the date the contribution is allocated. If the
                           contribution is


<PAGE>   28

                                      -24-

                           made prior to the date as of which it is to be
                           allocated, then such contribution shall not exceed an
                           amount that would cause an allocation to the suspense
                           account if the date of contribution were on the
                           allocation date. If an allocation is made to such
                           suspense account, it shall contain gains or losses.
                           Any such gains shall be viewed as an annual addition
                           at the time they are allocated to a Participant's
                           Account.

                  (1/l/87)

         (b)      Excess Deferrals

                  In the event the aggregate elective deferrals of a Participant
                  under one or more plans described in Sections 401(k), 408(k)
                  or 403(b) of the Code exceed $7,000.00 (adjusted for cost of
                  living changes as provided in Section 3.02) for any taxable
                  year of such Participant, the excess deferral amount for such
                  year that the Participant allocates to this Plan and income
                  allocable thereto shall be distributed no later than April 1
                  following the close of such taxable year, provided that the
                  Participant gives written notice on or before March 1
                  following the close of the taxable year specifying the excess
                  deferral amount allocated to this Plan and stating that if
                  such amounts are not distributed, such excess deferral amount,
                  when added to amounts deferred under other plans or
                  arrangements described in Sections 401(k), 408(k), or 403 (b)
                  of the Code, will exceed the limit imposed on the Participant
                  by Section 402(g) of the Code for the year in which the
                  deferral occurred. Notwithstanding a distribution under this
                  Section 3.10(b), any excess deferral amount allocated to this
                  Plan shall be treated as a 401(k) Contribution for purposes of
                  applying Section 3.09(b). (1/l/88; 7/l/96)

         (c)      Excess 401(k) Contributions

                  The Plan Administrator may suspend, reduce or prohibit all
                  401(k) Contributions made on behalf of Participants who are
                  Highly Compensated Employees for any Plan Year or part
                  thereof, if the Plan Administrator in its discretion
                  determines that such 401(k) Contributions may result in an
                  actual deferral percentage that exceeds the limits of Section
                  3.09(b). In the event the limits of Section 3.09(b) are
                  exceeded for any Plan Year, the excess contributions shall be
                  treated as provided in (i) or (ii) below:

                  (i)      At the Participant's written election, excess
                           contributions and income allocable thereto shall be
                           treated as an amount distributed to the Participant
                           and then contributed by the Participant to the Trust,
                           provided that such treatment does not cause the
                           limitations of Sections 3.09(a) or 3.09(c) to be
                           exceeded.

                  (ii)     For Plan Years ending on or before December 31, 1996,
                           except as otherwise elected in writing by a
                           Participant pursuant to (i) above, excess
                           contributions and income or loss allocable thereto
                           shall be distributed no

                           later than the last day of the following Plan Year to
                           Participants on whose behalf such excess
                           contributions were made. Any distribution of excess
                           contributions for any Plan Year shall be made to
                           Highly Compensated Employees on the basis of the
                           respective portions of the excess contributions
                           attributable to each of such Employees. For Plan
                           Years beginning on or after January 1, 1997, any
                           distribution of excess contributions for any Plan
                           Year shall be made to Highly Compensated Employees on
                           the basis of the amount of contributions by, or on
                           behalf of, each of such Employees. (1/1/97)

                  Allocable income or loss shall include income or loss for the
                  Plan Year in which the limits were exceeded. Allocable income
                  or loss shall be determined by multiplying the income or loss
                  for the Plan Year by a fraction, the numerator of which is the
                  excess contributions for the Plan Year and the denominator of
                  which is the Participant's account balance attributable to
                  401(k) Contributions, Matching Contributions and Qualified
                  Non-elective Contributions as of the end of the Plan Year
                  minus the income or plus the loss allocable to such account
                  balance for the Plan Year.

                  (1/1/88)

                  The term "excess contributions" means, with respect to any
                  Plan Year, the excess of (x) the aggregate amount of 401(k)
                  Contributions, Matching Contributions and Qualified
                  Non-elective Contributions actually paid over to the Trustees
                  on behalf of Highly Compensated Employees for such Plan Year,
                  over (y) the maximum amount of such contributions permitted
                  under the limitations of Section 3.09(b) (determined by
                  reducing contributions made on behalf of Highly Compensated
                  Employees in order of actual deferral percentages beginning
                  with the highest of such percentages).

                  (1/l/88)

         (d)      Excess Aggregate Contributions

                  In the event the limits of Section 3.09(c) are exceeded for
                  any Plan Year, excess aggregate contributions and income or
                  loss allocable thereto shall be forfeited, if otherwise
                  forfeitable under the terms of this Plan, or if not
                  forfeitable, distributed no later than the last day of the
                  following Plan Year to Participants to whose accounts such
                  After-Tax Contributions or Matching Contributions were
                  allocated. For Plan Years ending on or before December 31,
                  1996, any distribution of excess aggregate contributions for
                  any Plan Year shall be made to Highly Compensated Employees on
                  the basis of the respective portions of such amounts
                  attributable to each of such Employees. Forfeitures of excess
                  aggregate contributions may not be allocated to Participants
                  whose contributions are reduced under this paragraph. For Plan
                  Years beginning on or after January 1, 1997, any distribution
                  of excess aggregate contributions for any Plan Year shall be
                  made to Highly Compensated

                  Employees on the basis of the amount of contributions by, or
                  on behalf of, each of such Employees. (1/1/97)

                  Allocable income or loss shall include income or loss both for
                  the Plan Year in which the limits were exceeded. Allocable
                  income or loss shall be determined by multiplying the income
                  or loss for the Plan Year by a fraction, the numerator of
                  which is the excess aggregate contributions for the Plan Year
                  and the denominator of which is the Participant's account
                  balance attributable to After-Tax Contributions and Matching
                  Contributions as of the end of the Plan Year minus the income
                  or plus the loss allocable to such account balance for the
                  Plan Year.

                  The term "excess aggregate contributions" means, with respect
                  to any Plan Year, the excess of (x) the aggregate amount of
                  contributions taken into account in computing the contribution
                  percentage under Section 3.09(c) actually made on behalf of
                  Highly Compensated Employees for such Plan Year, over (y) the
                  maximum amount of such contributions permitted under the
                  limitations of Section 3.09(c) (determined by reducing
                  contributions made on behalf of Highly Compensated Employees
                  in order of their contribution percentages beginning with the
                  highest of such percentages). The determination of the amount
                  of excess aggregate contributions shall be made after first
                  applying the provisions of Sections 3.10(b) and 3.10(c).

3.11     CONTRIBUTIONS FOR TOP HEAVY PLAN YEARS

         For any Plan Year for which this Plan is deemed to be a Top Heavy Plan
         under the provisions of Section 1.47 of the Plan, the following
         provisions shall apply:

         (a)      The Employer shall contribute for each Participant who is not
                  a Key Employee not less than three (3%) percent of such
                  Participant's Compensation for the year, except as provided in
                  Section 3.11(b) below. For purposes hereof, any Participant
                  who has not separated from service at the end of the Plan Year
                  shall receive the minimum contribution provided for herein
                  without regard to the number of hours worked during the Plan
                  Year.

         (b)      The percentage referred to in Section 3.11(a) above for any
                  year shall not exceed the percentage at which contributions
                  are made under the Plan for such year for the Key Employee for
                  whom such percentage is the highest for the year. The
                  determination of the percentage at which contributions are
                  made for each Key Employee shall be made by dividing the
                  contribution for such Employee by so much of his Compensation
                  for the year as does not exceed the amount in effect under
                  Section 3.09(e). (7/l/96)

         (c)      The annual Compensation of each Employee taken into account
                  under this Plan shall not exceed $200,000 multiplied by the
                  Adjustment Factor. For Plan Years

         Matching Contributions Account only as provided herein.

         (a)      A Participant may, at any time after he has attained age 59

                                      -29-

         Any Participant who receives a hardship distribution under this Section
         4.04(c) shall be prohibited from making 401(k) Contributions under this
         Plan, as well as any other elective contributions to all other plans of
         deferred compensation maintained by the Employer, for a period of
         twelve (12) months after the date of receipt of the distribution. The
         Participant may elect to resume 401(k) Contributions as of the Entry
         Date which succeeds the date of the hardship distribution by at least
         twelve (12) months, provided that the Participant's 401(k)
         Contributions for his taxable year immediately following the taxable
         year of the distribution shall not exceed the limit set forth in
         Section 3.02 of this Plan decreased by the amount of the Participant's
         401(k) Contributions for the taxable year of the hardship distribution.
         An election to resume 401(k) Contributions must be made during the
         thirty (30) day period prior to the Entry Date on which the Participant
         wishes the resumption to be made effective.

         Hardship distributions under this Section 4.04(c) shall be limited to
         that portion of the Participant's 401(k) Account that is attributable
         to his 401(k) Contributions and shall not include any portion of such
         account that is attributable to income earned on such account after
         December 31, 1988. In addition, hardship distributions shall not
         include any portion of the Participant's 401(k) Account that is
         attributable to Qualified Non-elective Contributions or qualified
         employer matching contributions (if any) or any income earned thereon.

         (7/1/96)

         (d)      Upon a Participant's separation from service with the
                  Employer, whether by reason of death, disability, retirement
                  or termination of employment, distribution of the
                  Participant's 401(k) Account and Matching Contributions
                  Account shall be subject to the provisions of Article VI or
                  VII as the case may be.

                  (1/l/92)

4.05     PROCEDURES FOR PERMITTED WITHDRAWALS

         (a)      All requests for distributions under Sections 4.01, 4.03(a),
                  4.04(a) and 4.04(b) shall be made in accordance with
                  non-discriminatory procedures established by the Plan
                  Administrator. The minimum distribution amount shall be the
                  total balance of the Account or in increments of $100.00.
                  Distributions shall be made as soon as administratively
                  feasible following the request for withdrawal.

         (b)      Requests for hardship distributions under Sections 4.03(b) and
                  4.04(c) shall be made to the Plan Administrator. Distributions
                  shall be made as soon as administratively feasible following
                  approval of the request for distribution.

                  Hardship shall mean an immediate and heavy financial need of
                  the Participant where such Participant lacks other available
                  resources to meet the need. The amount of the hardship
                  distribution cannot exceed the amount necessary to satisfy the
                  need.


<PAGE>   34

                                      -30-

                  The following will be deemed immediate and heavy financial
                  needs: expenses incurred or necessary for medical care,
                  described in Code Section 213(d), of the Participant or the
                  Participant's spouse, children or dependents; payment of the
                  funeral expenses of a family member; payment of tuition,
                  related educational fees and room and board expenses for not
                  more than the next twelve months of postsecondary education
                  for the Participant, or the Participant's spouse, children or
                  dependents; the purchase (excluding mortgage payments) of a
                  principal residence for the Participant; or the need to
                  prevent the eviction of the Participant from, or a foreclosure
                  on the mortgage of, the Participant's principal residence.

                  A distribution will be deemed to be necessary to satisfy an
                  immediate and heavy financial need of the Participant only if
                  (i) the Participant has obtained all distributions, other than
                  hardship distributions, and all nontaxable loans under all
                  plans maintained by the Employer and (ii) the distribution is
                  not in excess of the amount necessary to meet the immediate
                  and heavy financial need (including amounts necessary to pay
                  any federal, state or local income taxes or penalties
                  reasonably anticipated to result from the distribution).

                  The Plan Administrator may determine that a distribution is
                  necessary to satisfy an immediate and heavy financial need of
                  the Participant if (i) the amount of the distribution is not
                  in excess of the amount required to relieve the need and (ii)
                  the need may not be satisfied from other resources that are
                  reasonably available to the Participant, including resources
                  of the Participant, the Participant's spouse and minor
                  children. In making this determination, the Plan Administrator
                  may rely upon the Participant's representation (unless the
                  Plan Administrator has actual knowledge to the contrary) that
                  the need cannot reasonably be relieved: (i) through
                  reimbursement or compensation by insurance or otherwise; (ii)
                  by liquidation of the Participant's assets; (iii) by cessation
                  of 401(k) Contributions (for hardship distributions from
                  401(k) Accounts); or (iv) by other distributions or nontaxable
                  (at the time of the loan) loans from plans maintained by the
                  Employer or by any other employer, or by borrowing from
                  commercial sources on reasonable commercial terms in an amount
                  sufficient to satisfy the need. For purposes of this
                  paragraph, a need cannot reasonably be relieved by one of the
                  actions listed above if the effect would be to increase the
                  amount of the need.

         (c)      If a distribution is to be made from any portion of a
                  Participant's Account that accrued prior to July 1, 1996 and
                  if the Participant is married, the spouse of the Participant
                  must consent to any lump sum distribution in excess of $3,500.
                  The spouse's consent must be in writing and must acknowledge
                  the effect of the election. The spouse's signature must be
                  witnessed by a Plan representative or a notary public.

         (d)      amounts withdrawn by a Participant may not be returned to the
                  Trust.

4.06     LOANS TO PARTICIPANTS

         The Plan Administrator may, subject to rules of uniform application,
         authorize the Trustee to make loans to a Participant or to a
         Beneficiary, subject to the provisions of this Section 4.06.

         (a)      Loans under this Section 4.06 may be made to any Participant,
                  or to any former Participant or Beneficiary who is a party in
                  interest under ERISA with respect to this Plan, so long as
                  such individual has an account balance in his 401(k) account,
                  Rollover Account and/or Matching Contributions Account.
                  (1/1/92)

         (b)      The amount of any loan to a Participant or Beneficiary, when
                  added to the outstanding balance of all other loans from this
                  Plan or a related plan to such Participant or Beneficiary,
                  shall be limited to one-half of the present value of the
                  Participant's or Beneficiary's vested interest in his 401(k)
                  Account, Matching Contributions Account and Rollover Account,
                  but shall not be more than fifty thousand ($50,000) dollars
                  reduced by the excess, if any, of the highest outstanding
                  balance of loans from the Plan during the one-year period
                  ending on the day before the date on which the loan is made,
                  over the outstanding balance of loans from the Plan on the
                  date on which the loan is made. (1/1/92)

         (c)      The minimum loan amount shall be $1,000 and the loan amount in
                  excess of the minimum shall be in increments of $100.00.

         (d)      Loans shall be made available to eligible Participants and
                  Beneficiaries on a reasonably equivalent basis. The Plan
                  Administrator may, however, reasonably decide to approve or
                  deny a loan based upon an applicant's credit worthiness, other
                  outstanding financial obligations, financial need and other
                  factors that the Plan Administrator determines may adversely
                  affect repayment of the loan. The Plan Administrator may
                  charge a loan administration fee.

         (e)      Any loan hereunder shall be evidenced by a valid promissory
                  note, payable on a date or dates certain, with interest at a
                  rate to be established by the Plan Administrator with
                  reference to the then-current interest rates available from
                  commercial lending institutions for similar loans. Monthly
                  payments shall be in an amount that results in substantially
                  level amortization of the principal and interest of the loan
                  over the terms of the loan. Unless the loan is to be used to
                  acquire any dwelling unit which, within a reasonable time of
                  the date of the loan, is to be used as a principal residence
                  of the Participant, the note shall provide that the loan is to
                  be repaid within a period not exceeding five (5) years. The
                  note shall also provide that the loan will become due and
                  payable prior to the end of such period in the event of
                  default by the borrower as defined below.

         (f)      If the borrower is an Employee of the Employer, he shall
                  authorize the Employer to withhold the amount of his periodic
                  payments under the note from his compensation and to pay such
                  amounts directly to the Trustee.

                                      -32-

         (g)      The Plan Administrator may require adequate security for the
                  loan, determined with reference to the type and amount of
                  security which would be required in the case of a similar
                  arms-length transaction between unrelated parties in a
                  commercial setting. The Participant's or Beneficiary's
                  401(k)Account, Matching Contributions Account and Rollover
                  Account may be used as security for a loan, but only 50% of
                  the present value of his vested interest in such Accounts,
                  determined as of the origination of the loan, may be
                  considered in determining the adequacy of such security. If
                  any portion of such Accounts that accrued prior to July 1,
                  1996 is to be used as security, the spouse of a married
                  Participant must consent in writing to the use of the Accounts
                  as security and such consent must be given at the time the
                  security interest is entered into.

         (h)      A Participant or Beneficiary shall be in default with respect
                  to any loan granted hereunder, and the note will become due
                  and payable upon demand, upon the occurrence of any of the
                  following:

                  (1)      Failure by the borrower to pay when due any interest
                           or principal or both under the note;

                  (2)      The occurrence of an event of default under any other
                           note of the borrower to the Trustee;

                  (3)      If any property pledged as security for the note
                           becomes subject to attachment or garnishment;

                  (4)      If any property pledged as security for the note is
                           disposed of without prior substitution of other
                           security satisfactory to the Plan Administrator; or

                  (5)      The occurrence of an event requiring the commencement
                           of benefit payments or a distribution of the
                           borrower's vested interest in his Accounts under the
                           Plan.

                  In the event the Borrower makes an assignment for the benefit
                  of creditors, files a petition in bankruptcy, is adjudicated
                  insolvent or bankrupt, or becomes a subject of any wage earner
                  plan under state or federal law, or in the event a bankruptcy
                  or similar proceeding is commenced against borrower to which
                  borrower consents, assents or acquiesces, or which remains
                  undismissed or stayed for a period of 60 days, the note will
                  become immediately due and payable.

         (i)      The Plan Administrator shall take such actions as it deems
                  reasonable and prudent to collect such amounts as are due and
                  unpaid including but not limited to foreclosure on the
                  security interest given to secure the loan. If the security
                  interest is the Participant's or Beneficiary's 401(k) Account,
                  Matching Contributions Account and/or Rollover Account the
                  Plan Administrator may direct the Trustee to deduct such
                  amounts from such Account or Accounts, in which event such
                  amounts shall be treated as distributed to the borrower and
                  applied by the

                                      -33-

                  borrower as a payment of the unpaid principal and interest
                  under the note. The Plan Administrator shall not, however,
                  take any action that would result in a disqualifying
                  distribution under the Plan.

         (j)      Any loan granted under this Section 4.06 shall be deemed to be
                  made first from the borrower's 401(k) Account, then from his
                  Matching Contributions Account, then from his Rollover
                  Account, and the investment experience of such loan shall be
                  credited to (or deducted from) the borrower's said Accounts in
                  the proportion in which the fiends were borrowed. (1/ I /92)

         (10/l/89; Rollover Accounts added effective 1/l/92;7/l/96)

4.07     DISTRIBUTIONS PURSUANT TO QUALIFIED DOMESTIC RELATIONS ORDER

         All or a specified portion of a Participant's vested interest in his
         Participant's Account may be distributed to an Alternate Payee in the
         form of a single sum cash distribution pursuant to a qualified domestic
         relations order which meets the requirements of Section 414(p) of the
         Code prior to the time the Participant would be entitled to a
         distribution under the Plan. The distribution shall be made as soon as
         administratively feasible following the close of the calendar quarter
         coinciding with or next following a determination by the Plan
         Administrator that a domestic relations order is qualified. This
         section shall not be interpreted as requiring that a domestic relations
         order provide for an Alternate Payee's benefit to be paid in a
         particular form or at a particular time in order to be qualified.

                           Service shall be taken into account in determining
                           his vested interest in his Profit Sharing Account
                           and/or Matching Contributions Account.

                  (2)      In the case of a Participant who has incurred five
                           (5) or more consecutive Breaks in Service, and who
                           has retained a vested interest in this Plan, separate
                           accounts will be maintained for the Profit Sharing
                           Contributions and Matching Contributions accrued
                           prior to such Breaks and Profit Sharing Contributions
                           and Matching Contributions accrued after such Breaks.
                           Years of Service after such Breaks shall be
                           disregarded for purposes of determining such
                           Participant's vested interest in his pre Break Profit
                           Sharing Account and/or Matching Contributions
                           Account, and all Years of Service shall be taken into
                           account in determining his vested interest in his
                           post Break Profit Sharing Account and/or Matching
                           Contributions Account.

                           taken into account for purposes of determining such
                           Participant's vested interest after re-employment
                           with the Employer unless the number of his
                           consecutive Breaks in Service equals or exceeds five
                           (5), in which case pre-break service shall be
                           disregarded. (1/l/88)

         (b)      For purposes of determining whether a Participant has incurred
                  a Break in Service, the following provisions shall apply in
                  the case of any individual who is absent from work for any
                  period by reason of the pregnancy of the individual, the birth
                  of a child of the individual, the placement of a child with
                  the individual in connection with the adoption of such child
                  by such individual, or for purposes of caring for such child
                  for a period beginning immediately following such birth or
                  placement.

                  (1)      The following hours shall be treated as Hours of
                           Service under the Plan:

                           (i)      the Hours of Service which otherwise
                                    normally would have been credited to such
                                    individual but for such absence, or

                           (ii)     eight (8) hours per day of such absence, if
                                    the actual number of hours described in
                                    paragraph (i) cannot be determined;

                                    except that the total number of hours
                                    treated as Hours of Service hereunder shall
                                    not exceed 501 hours.

                  (2)      The hours described in subsection (1) above shall be
                           treated as Hours of Service only in the Plan Year in
                           which the absence from work begins, if a Participant
                           would be prevented from incurring a Break in Service
                           in such year solely because the period of absence is
                           treated as Hours of Service as

                           provided in subsection (1) above, or otherwise in the
                           immediately following year.

                  (3)      The Plan Administrator may require a Participant to
                           provide reasonable evidence to establish that the
                           absence from work is covered by these provisions and
                           the number of days for which there was such an
                           absence.

         (a)      For any Participant whose Participant Account includes
                  benefits accrued on or before June 30, 1996 (or, for benefits
                  accrued under the Zycon Corporation Profit Sharing 401(k)
                  Plan, benefits accrued on or before September 30, 1997),
                  within a reasonable time before or after the Participant's
                  annuity starting date consistent with regulations of the
                  Secretary of the Treasury, the Plan Administrator shall notify
                  the Participant in writing of:

                  (i)      the terms and conditions of a Qualified Joint and
                           Survivor Annuity;

                  (ii)     the Participant's right to make and the effect of an
                           election to waive the Qualified Joint and Survivor
                           Annuity form of benefit;

                  (iii)    the rights of a Participant's spouse; and


<PAGE>   47

                                      -43-

                  (iv)     the right to make, and the effect of, a revocation of
                           a previous election to waive the Qualified Joint and
                           Survivor Annuity.

                  The Plan Administrator shall also provide a Participant with a
                  written explanation, in nontechnical language, of each of the
                  forms of benefits described in Section 6.01 (c) above, and the
                  financial consequences and legal ramifications, if any,
                  contained therein, at the same time as the said notice
                  concerning the Qualified Joint and Survivor Annuity is given.
                  (10/l/97)

         (b)      In the case of a qualified pre-retirement survivor annuity,
                  for any Participant whose Participant Account includes
                  benefits accrued on or before June 30, 1996 (or, for benefits
                  accrued under the Zycon Corporation Profit Sharing 401(k)
                  Plan, benefits accrued on or before September 30, 1997), the
                  Plan Administrator shall provide each married Participant
                  within the period beginning on the first day of the Plan Year
                  in which the Participant attains age 32 and ending with the
                  close of the Plan Year in which the Participant attains age
                  35, a written explanation of the qualified pre-retirement
                  survivor annuity in such terms and in such manner as would be
                  comparable to the explanation provided for meeting the
                  requirements of subsection (a) above applicable to a Qualified
                  Joint and Survivor Annuity. If a Participant enters the Plan
                  after the first day of the Plan Year in which the Participant
                  attained age 32, the Plan Administrator shall provide notice
                  no later than the close of the second Plan Year after the
                  entry of the Participant in the Plan. (10/l/97)

         (c)      Notwithstanding the other requirements of this Section 6.04,
                  the respective notices prescribed by this section need not be
                  given to a Participant if the Plan "fully subsidizes" the
                  costs of a Qualified Joint and Survivor Annuity or qualified
                  pre-retirement survivor annuity. For purposes of this
                  subsection, the Plan fully subsidizes the costs of a benefit
                  if under the Plan the failure to waive such benefit by a
                  Participant would not result in a decrease in any Plan benefit
                  with respect to such Participant and would not result in
                  increased contributions from the Participant.

         (d)      A Participant may elect to waive a benefit in the form of a
                  Qualified Joint and Survivor Annuity and a married Participant
                  may waive the death benefit in the form of a qualified
                  pre-retirement survivor annuity, provided that the waiver must
                  be in writing and must be consented to by the Participant's
                  spouse. The spouse's consent must acknowledge the effect of
                  the election and must be witnessed by a Plan representative or
                  notary public. Notwithstanding this consent requirement, if
                  the Participant establishes to the satisfaction of a Plan
                  representative that such written consent may not be obtained
                  because there is no spouse or the spouse cannot be located, a
                  waiver signed only by the Participant will be deemed a
                  qualified election. Any consent necessary under this provision
                  will be valid only with respect to the spouse who signs the
                  consent, or in the event of a deemed qualified election, the
                  designated spouse. Additionally, a revocation of a prior
                  waiver may be made by a Participant without the consent of the
                  spouse at any time

                                      -44-

                  before the commencement of benefits. The number of waivers or
                  revocations shall not be limited.

         (e)      The election to waive a Qualified Joint and Survivor Annuity
                  must be made within the ninety (90) day period ending on the
                  date the Participant's benefits would commence or, if later,
                  no sooner than thirty (30) days from the date the written
                  notice described in this section was given; provided, however,
                  that a distribution cannot be made sooner than thirty (30)
                  days from the date such notice was given unless the
                  Participant (and, if applicable, the Participant's spouse)
                  consents and the distribution commences at least seven (7)
                  days after the date of such notice. Any consent shall satisfy
                  such requirements as may be prescribed under regulations of
                  the Secretary of the Treasury. (10/l/97)

         (f)      The election to waive a qualified pre-retirement survivor
                  annuity must be made within the period which begins on the
                  first day of the Plan year in which the Participant attains
                  age 35 and ends on the date of the Participant's death;
                  provided that, if a Participant separates from service prior
                  to the first day of the Plan Year in which age 35 is attained,
                  the election period with respect to the Participant's account
                  balance as of the date of separation shall begin on the date
                  of separation from service.

         If the value of the Participant's vested interest in his Participant's

         Plan Administrator may direct the distribution of such amount as a lump
         sum cash payment to the Participant, whether or not the Participant has
         filed an election under this Article VI. For Plan Years beginning on or
         after January 1, 1998, the $3,500.00 dollar limit stated above shall be
         changed to $5,000.00. (7/1/96; 1/1/98)

                                   ARTICLE VII

                            TERMINATION OF EMPLOYMENT

7.01     TERMINATION DISTRIBUTIONS

         Upon the termination of a Participant's employment with the Employer,
         other than by reason of the Participant's retirement, disability or
         death, the Participant's vested interest in his Participant's Account
         shall be determined as of his date of termination in accordance with
         Article V of this Plan. The Participant may elect to receive a lump sum
         distribution of his vested interest in his Participant's Account valued
         as of the date of distribution at any time after he has separated from
         service on account of his termination of employment. Such lump sum
         distribution shall be made as soon as administratively practicable
         after the later of (i) the date the Participant becomes eligible to
         receive such distribution or (ii) the date the Plan Administrator
         receives notice meeting the requirements set out below.

         Any election to receive a lump sum distribution of a Participant's
         vested interest in his Participant's Account must be made by notice to
         the Plan Administrator. If any portion of the Participant's Account was
         accrued on or before June 30, 1996 (or, for benefits originally accrued
         under the Zycon Corporation Profit Sharing 401(k) Plan, on or before
         September 30, 1997) and if the Participant is married, the spouse of
         the Participant must consent to any lump sum distribution in excess of
         $3,500. The spouse's consent must be in writing and must acknowledge
         the effect of the election. The spouse's signature must be witnessed by
         a Plan representative or a notary public.

         Notwithstanding the foregoing, if the value of the Participant's vested
         interest in his Participant's Account upon termination of employment is
         $3,500 or less, the Plan Administrator may direct the distribution of
         such amount as a lump sum cash payment to the Participant, whether or
         not the Participant has made an election under this Section 7.01. For
         Plan Years beginning on or after January 1, 1998, the $3,500.00 dollar
         limit stated herein shall be changed to $5,000.00.

         (7/l/89; 7/l/96; 10/l/97; 1/1/98)

7.02     TERMINATION FORFEITURES

         A Participant whose employment with the Employer is terminated as
         described in Section 7.01 of this Article, and who has not received a
         distribution of the vested portion of his Profit Sharing Account and/or
         Matching Contributions Account, shall forfeit the value of that portion
         of his Profit Sharing Account and/or Matching Contributions Account in
         which he was not vested at the date of his termination of employment as
         of the Valuation Date coincident with or next following the date he
         incurs five (5) consecutive Breaks in Service after such termination of
         employment. A Participant who has received a distribution of the vested
         portion of his


<PAGE>   51

                                      -47-

         Profit Sharing Account and/or Matching Contributions Account under
         Section 7.01 shall forfeit the value of the portion of his Profit
         Sharing Account and/or Matching Contributions Account in which he was
         not vested at the date of his termination of employment as of December
         31 of the Plan Year in which such distribution was made, provided that
         such forfeited amounts may be reinstated as provided in Section 7.03 of
         this Article. Except as provided in Article XII hereof, any amounts so
         forfeited by Participants shall be allocated to remaining Participants
         in accordance with Section 3.07 of Article III.

         If the Participant's employment with the Employer is terminated as
         described in Section 7.01 of this Article, and he subsequently resumes
         employment with the Employer prior to receiving a distribution of his
         vested interest in his Profit Sharing Account and/or Matching
         Contributions Account, the then current value of the nonvested portion
         of his Profit Sharing Account and/or Matching Contributions Account
         shall not be forfeited on account of such termination of employment and
         shall continue to be maintained in said Profit Sharing Account and/or
         Matching Contributions Account.

         (1/1/88)

7.03     REPAYMENT TO REINSTATE FORFEITED AMOUNTS

         (a)      A former Participant who has received a distribution from the
                  Plan pursuant to Section 7.01, and who resumes employment with
                  the Employer prior to incurring five (5) consecutive Breaks in
                  Service, shall have reinstated that portion of his Profit
                  Sharing Account and/or Matching Contributions Account which
                  was forfeited under Section 7.02 upon repayment by the
                  Participant of the full distribution made to him. Such
                  repayment must be made before the end of a period of five (5)
                  consecutive Breaks in Service after the distribution.

         (b)      The amount to be credited to the Participant's Profit Sharing
                  Account and/or Matching Contributions Account upon repayment
                  shall not be less than the balance of the Participant's Profit
                  Sharing Account and/or Matching Contributions Account at the
                  time of distribution, including both the amount distributed
                  and the nonvested amount, unadjusted by any subsequent gains
                  or losses.

         (c)      In the event that the Participant elects not to make the
                  repayment described in subsection (a) above, the forfeited
                  amounts shall not be taken into account in computing his
                  accrued benefit under this Plan.

         (1/l/88)

                                  ARTICLE VIII

                            INVESTMENT OF TRUST FUNDS

8.01     TRUSTEE'S RESPONSIBILITY

         The Trustee shall have general authority to invest, manage and maintain
         custody of the trust assets, in accordance with the terms of the Trust
         and subject to the following provisions of this Article VIII.
         (1/l/92)

8.02     DIRECTED INVESTMENTS OF PARTICIPANT ACCOLTNTS

         Each Participant shall be permitted to direct the Trustee as to the
         investment of his Participant Account in accordance with the investment
         alternatives selected by the Investment Committee and offered by the
         Trustee. Upon receiving a direction from a Participant, the Trustee
         shall segregate that portion of the Participant's Account to which such
         direction applies from the remainder of the trust fund and invest it in
         accordance with the Participant's direction. The Participant's Account
         shall be credited or charged with the gains and losses resulting from
         such directed investment and such gains and losses shall not be
         considered in determining gains or losses of the remainder of the trust
         fund. A Participant shall have the opportunity to change his investment
         directions with respect to all or any portion of his Participant
         Account not less frequently than once in any three-month period, or
         more frequently if administratively feasible.

         In the event a Participant fails to direct the Trustee as to the
         investment of all or any part of the Participant's Account, that
         portion of the account as to which no direction has been given shall be
         invested by the Trustee in accordance with instructions from the
         Investment Committee. The Trustee also shall change the investment of
         all or any part of a Participant's Account if so directed by the
         Investment Committee.

         No Participant shall be deemed a Plan Fiduciary by reason of giving
         investment directives hereunder, and no person who is otherwise a Plan
         Fiduciary shall be liable for any loss attributable to such directed
         investments, or for any result of a Participant's exercise of control
         over the investment of his accounts which would otherwise constitute a
         breach of fiduciary responsibility.

         (1/l/89; 7/l/96)

8.03     INVESTMENT COMMITTEE

         (a)      Appointment and General Responsibilities

                  The Employer shall appoint an Investment Committee consisting
                  of three employees who shall serve at the pleasure of the
                  Employer's Board of Directors. The members of the Investment
                  Committee shall be Plan Fiduciaries.


<PAGE>   53

                                      -49-

                  The Investment Committee shall be responsible for establishing
                  and maintaining the investment strategies and funding policies
                  for the Plan and Trust, including but not limited to
                  determining the need for short term or long term liquidity
                  and/or for investment growth, coordinating the investment
                  policy with Plan and Trust needs, and communicating those
                  policies to the Trustee and investment manager, if any. The
                  Investment Committee shall be responsible for selecting
                  investment alternatives for Participant-directed investments
                  permitted under this Plan and for giving the Trustee
                  investment directions with respect to that portion of any
                  Participant Account for which directions have not been given
                  by the Participant to the Trustee and with respect to that
                  portion of the trust fund which is not then allocated to any
                  Participant's Account. (1/1/89; 7/1/96)

                  Any act which the Investment Committee is authorized or
                  required to do may be done by a majority of the members of the
                  Committee at the time acting hereunder and the action of such
                  majority, expressed from time to time by a vote at a meeting
                  or in writing without a meeting, shall constitute the action
                  of the Committee and shall have the same effect for all
                  purposes as if assented to by all members of the Committee at
                  the time in office. In the event of a vacancy on the
                  Committee, the action by the remaining member or members shall
                  be valid and binding. Any such vacancy shall be filled within
                  a reasonable time. (1/l/92)

                  No member of the Committee who receives full time compensation
                  from the Employer shall receive any compensation or fee for
                  his services as a member of the Committee, but may be
                  reimbursed for his expenses.

         (b)      Right to Appoint Investment Managers

                  The Investment Committee may appoint and dismiss one or more
                  investment managers who shall have the power to manage,
                  acquire or dispose of any of the assets of the Trust,
                  including but not limited to the selection of investment
                  alternatives for Participant-directed investments permitted
                  under this plan. The Committee shall designate the portion of
                  the assets of the Trust which shall be subject to the
                  management of any such investment manager and shall so notify
                  the Trustee in writing. The Committee may authorize payment
                  for the services of an investment manager from the trust. (1 /
                  1/92)

                  Any investment manager must be (i) registered as an investment
                  adviser under the Investment Advisers Act of 1940, or (ii) a
                  bank, as defined in that Act, or (iii) an insurance company
                  qualified to perform trust management and investment services
                  under the laws of more than one state; and must acknowledge in
                  writing that he or it is a Fiduciary with respect to the Plan
                  and Trust.

         (c)      Adoption of Group Trust

                  The Investment Committee may adopt, as part of the Trust, any
                  group trust in which any of the assets of the Trust are or are
                  to be invested, and may authorize


<PAGE>   54

                                      -50-

                  the participation of the Trust in such group trust, but only
                  so long as such group trust remains exempt from taxation under
                  Section 501 (a) of the Code, in accordance with Revenue Ruling
                  81-100. For purposes hereof, the term "group trust" shall
                  include any common, collective, multiple or commingled trust

                                    must be nontransferable. Any contract for
                                    the lives of the Participant and a
                                    designated Beneficiary shall be a 50%,

                                      -53-

                                    made over a period not to exceed the
                                    Participant's (or the Participant's and
                                    spouse's) life expectancy, subject to the
                                    terms set forth herein. The Participant may
                                    elect either:

                                    (1)     payment in equal amounts, except
                                            that the last payment which exhausts
                                            the Participant's Radian Source
                                            Accounts may be greater or smaller;

                                    (2)     a specific number of payments. The
                                            amount of each payment will equal
                                            the then value of the Participant's
                                            Radian Source Accounts divided by
                                            the number of remaining payments to
                                            be made; or

                                    (3)     payments over the Participant's life
                                            expectancy re-determined each year.
                                            The amount of each payment will
                                            equal the then value of the
                                            Participant's Radian Source Accounts
                                            divided by the Participant's
                                            life expectancy.

                                    An amount may be deducted from a
                                    Participant's Radian Source Account to cover
                                    the expenses applicable to such installment
                                    payment options. Installment payments will
                                    terminate with the earlier of (a) the
                                    payment which completely exhausts the
                                    Participant's Radian Source Accounts or (b)
                                    the last payment due preceding the death of
                                    the Participant. At the death of the
                                    Participant, any amount remaining in the
                                    Participant's Radian Source Accounts will be
                                    paid in a lumpsum to the Participant's
                                    Beneficiary or Beneficiaries. In no event
                                    will the installment period exceed that
                                    permitted by law.

         (b)      Termination Of Employment

                  (i)      NOTICE OF TERMINATION OF EMPLOYMENT. If the
                           termination of employment of a Participant occurs,
                           the Employer shall give written notice to the Plan
                           Administrator of the date of termination of
                           employment of such Participant.

                  (ii)     AMOUNT OF PARTICIPANT'S BENEFIT. The amount of a
                           Participant's Plan benefit upon termination of
                           employment which is subject to the terms of this
                           Article VIII-A shall equal the total balance of his
                           Radian Source Accounts at the time of determination.

                  (iii)    PARTICIPANT'S ELECTION OF A FORM OF BENEFIT. If
                           termination of employment occurs, the Participant
                           shall receive his Radian Source Accounts in a form of
                           benefit elected by him. The Participant's election

                                    the annuity was purchased to the date of the
                                    Participant's death.

                           (C)      OPTION C. The Participant may elect a

                           If the value of the Participant's Radian Source
                           Accounts exceeds (or at the time of any prior

                           and the Accounts are immediately distributable, the
                           Participant and the Participant's spouse (or where

                           Accounts are no longer immediately distributable. The
                           notice shall acknowledge the right, if any, to defer
                           distributions and must describe the investment
                           features. One-sum cash payments shall be made during

                  (i)      PRERETIREMENT DEATH OF A PARTICIPANT. If the

                           shall be paid to the Participant's surviving spouse.

                           Participant dies after distribution of his interest
                           in the Radian Source Accounts has begun, the
                           remaining portion of such interest shall continue to
                           be distributed at least as rapidly as under the
                           method of distribution begin used prior to the
                           Participant's death. In the case of an installment
                           payment option, installment payments remaining at the
                           Participant's death shall be distributed to the
                           Participant's designated Beneficiary as a one-sum

         spouse, or for any other relative of the Employee, prior to actually
         being received by the person entitled to the benefit under the terms of
         the Plan; and any attempt to anticipate, alienate, sell, transfer,
         assign, pledge, encumber, charge or otherwise dispose of any right to
         benefits payable hereunder, shall be void. The Plan assets shall not in
         any manner be liable for, or subject to the debts, contracts
         liabilities, engagements or torts of any person entitled to benefits
         hereunder. Nothing herein shall be construed as preventing the
         assignment of all or part of a Participant's interest in this Plan
         pursuant to a qualified domestic relations order which meets the
         requirements of Sections 401(a)(13) and 414(p) of the Code. (1/1/85)

10.04    DISCONTINUANCE OF EMPLOYER CONTRIBUTIONS

         In the event of complete discontinuance of contributions under this
         Plan to the Trust by the Employer, within the meaning of Section 411(d)
         of the Code and the related regulations, the accounts of all
         Participants shall, as of the date of such discontinuance, become fully
         vested.

10.05    NO REVERSION IN EMPLOYER

         The Employer has no beneficial interest in the Trust assets and no part
         of the Trust assets shall ever revert or be repaid to the Employer,
         directly or indirectly, except that if the Internal Revenue Service
         initially determines that the Plan does not meet the


<PAGE>   66

                                      -62-

         requirements of Section 401(a) of the Internal Revenue Code, any assets
         attributable to contributions made by the Employer under the Plan shall
         be returned to the Employer within one calendar year of denial of
         qualification of the Plan.

10.06    JURISDICTION

         This Plan shall be construed in accordance with the laws of the
         jurisdiction of the Commonwealth of Massachusetts except to the extent
         to which said laws are superseded by Federal Law.

10.07    TIMING OF DISTRIBUTIONS

         (a)      The distribution of any benefits under this Plan shall begin,
                  unless otherwise elected by the Participant, no later than the
                  sixtieth (60th) day after the latest of the close of the Plan
                  Year in which (i) the Participant attains age sixty-five (65),
                  (ii) occurs the tenth (tenth) anniversary of the time the
                  Participant commenced participation in the Plan, or (iii) the
                  Participant terminates his employment with the Employer.

         (b)      Any distribution to be made due to a Participant's termination
                  of employment prior to his Normal Retirement Date shall begin
                  no later than the sixtieth (60th) day following the date he
                  has incurred five (5) consecutive Breaks in Service for
                  vesting computation purposes, unless the Participant otherwise
                  elects to defer payment to a date specified in the preceding
                  Subsection (a). (1/l/85)

         (c) The entire interest of a Participant either:

                  (i)      will be distributed to him not later than the
                           required beginning date, as defined below, or

                  (ii)     will be distributed, commencing not later than such
                           required beginning date, (A) in accordance with
                           regulations prescribed by the Secretary of the
                           Treasury, over the life of such Participant or over
                           the lives of such Participant and a designated
                           beneficiary or (B) in accordance with such
                           regulations, over a period not extending beyond the
                           life expectancy of such Participant or the life
                           expectancy of such Participant and a designated
                           beneficiary.

                  As used herein, for Plan Years ending on or before December
                  31, 1996, the term "required beginning date" means April 1 of
                  the calendar year in which the Participant attains age 70 1/2.
                  For Plan Years beginning on or after January 1, 1997, the term
                  "required beginning date" means April 1 of the calendar year
                  following the later of (I) the calendar year in which the
                  Participant attains age 70 1/2 or (II) the calendar year in
                  which the Participant retires; provided, however, that clause
                  (II) shall not apply in the case of a Participant who is a
                  five percent owner with respect to the Plan Year in which he
                  attains age 70 1/2. In the case of a Participant to whom
                  clause (II) applies who retires in a calendar year after the


<PAGE>   67

                                      -63-

                  calendar year in which he attains age 70 1/2, the
                  Participant's accrued benefit shall be actuarially increased
                  to take into account the period after age 70 1/2 in which the
                  Participant was not receiving any benefits under the Plan. The
                  determination of who is a five percent owner shall be made in
                  accordance with Section 416(i) of the Code and the regulations
                  thereunder.

         (1/l/87; 1/l/97)

         (d)      If distribution of a Participant's interest has begun in
                  accordance with subsection 10.07(c)(ii) above and the
                  Participant dies before his entire interest is distributed to
                  him, the remaining portion of such interest will be
                  distributed at least as rapidly as under the method of
                  distribution being used as of the date of his death.

         (e)      If a Participant dies before the distribution of his interest
                  has begun in accordance with subsection 10.07(c)(ii) above,
                  the entire interest of the Participant will be distributed in
                  accordance with the following provisions:

                  (i)      Any portion payable to or for the benefit of a
                           designated beneficiary will be distributed in
                           accordance with applicable regulations over the life
                           of such designated beneficiary, or over a period not
                           extending beyond the life expectancy of such
                           beneficiary, beginning not later than one year after
                           the date of the Participant's death; or

                  (ii)     Any portion payable to or for the benefit of a
                           designated beneficiary who is the surviving spouse of
                           the Participant will be distributed as provided in
                           the preceding clause (i) beginning not later than the
                           date on which the Participant would have attained age
                           seventy and one-half (70 1/2); provided that if the
                           surviving spouse dies before the distributions to
                           such spouse begin, this subsection 10.07(e) shall be
                           applied as if the surviving spouse were the
                           Participant; or

                  (iii)    If neither of the preceding clauses (i) and (ii)
                           apply, the entire interest of the Participant will be
                           distributed within five (5) years after the death of
                           such Participant.

10.08    BENEFICIARY DESIGNATIONS

         (a)      Except as provided in subsection (b) below, the Participant
                  shall have the unrestricted right to designate, and to rescind
                  or change any designation of, a primary and contingent
                  Beneficiary or Beneficiaries to receive any benefit due in the
                  event of his death. Each such rescission or change of
                  Beneficiary(ies) must be made in writing to the Plan
                  Administrator and must be signed by the Participant. If there
                  is no designated Beneficiary living when the death benefit
                  becomes payable or if no such designation of Beneficiary is on
                  file with the Plan Administrator, or if in the sole discretion
                  of the Plan Administrator such designation is defective, any
                  death benefit due will be paid to any one or more of


<PAGE>   68

                                      -64-

                  the surviving members of the Participant's relatives in the
                  following order of preference:

                  (i)      to his spouse;

                  (ii)     in equal shares to his children;

                  (iii)    to his parents; or

                  (iv)     to his estate.

         (b)      If a Participant who is married wishes to designate a primary
                  Beneficiary who is not the spouse of such Participant, such
                  designation shall not be effective unless the spouse of such
                  Participant consents in writing to such designation. The
                  written consent of the spouse must acknowledge the effect of
                  such consent, and must be witnessed by a plan representative
                  or a notary public. Any consent by a spouse hereunder shall be
                  effective only with respect to that spouse.

         (1/l/85)

10.09    BENEFITS OF LOST PARTICIPANTS

         The provisions of this Section 10.09 shall apply in the event a
         Participant or Beneficiary fails to file an application for benefits,
         or in the event of the termination of the Plan or other event requiring
         distribution of a benefit or other Plan assets to a Participant or
         Beneficiary, if the Participant or Beneficiary cannot be located.

         (a)      The Plan Administrator shall give written notice to each
                  Participant at his last known address of his right to receive
                  a distribution under the Plan, within a reasonable time after
                  the happening of an event giving rise to the right to receive
                  the distribution. Without limiting the generality of the
                  preceding sentence, a decision by the Plan Administrator to
                  direct the distribution of a Participant's Account having a
                  vested value of $3,500 or less shall be an event requiring
                  distribution of a benefit. (1/l/93)

         (b)      If the Participant cannot be located in this manner, the
                  account of such Participant shall continue to be held in a
                  Participant Account under the Plan until the occurrence of an
                  event described in any of Sections 10.09(c), (d) or (e)
                  following.

         (c)      If proof of death of the Participant satisfactory to the Plan
                  Administrator is received by the Plan Administrator, the
                  benefit or other distribution shall be paid to the
                  Participant's Beneficiary.

         (d)      If the Plan is terminated prior to distribution of the benefit
                  or other amount due, the Plan Administrator shall establish an
                  interest bearing custodial account for the benefit of the
                  Participant or his Beneficiary in a federally insured bank,
                  savings and loan association, or credit union, into which the
                  Participant's account balance


<PAGE>   69

                                      -65-

                  shall be deposited. Such account shall be held in trust for
                  the benefit of the Participant or his Beneficiary.

         (e)      If no claim is made by a Participant or his Beneficiary within
                  one year of the date notice is given of the right to receive a
                  distribution under the Plan, the benefit payable to or account
                  balance of such Participant shall be forfeited; provided that
                  such forfeited benefit or amount shall be reinstated in the
                  event a valid claim for such amount is subsequently made by
                  the Participant or his Beneficiary. Any forfeiture hereunder
                  shall be treated as a Forfeiture under Section 3.07 of the
                  Plan for the year in which it occurs.

         (1/l/85)

10.10    DIRECT TRUSTEE-TO-TRUSTEE TRANSFER OPTION

         Whenever a Participant, Beneficiary or Alternate Payee under a
         qualified domestic relations order is to receive a distribution under
         the Plan that is an eligible rollover distribution, as hereinafter
         defined, that would otherwise be subject to withholding under Section
         3405(c) of the Code, the distributee may elect by written notice to the
         Plan Administrator to have all or a specified portion of such
         distribution paid directly to a specified eligible retirement plan in a
         trustee-to-trustee transfer. The Plan Administrator shall prescribe
         reasonable procedures for a distributee to elect a direct rollover,
         including information and documentation to be provided and the time
         period within which such election may be made, and shall provide notice
         of this option to each distributee within a reasonable time prior to
         making an eligible rollover distribution.

         As used in this Section 10.10, an eligible rollover distribution means
         any distribution that is described in Section 402(c)(4) of the Code and
         the regulations thereunder.

         As used in this Section 10.10, an eligible retirement plan generally is
         an individual retirement account described in Section 408(a) of the
         Code, an individual retirement annuity (other than an endowment
         annuity) described in Section 408(b) of the Code, a qualified trust
         forming part of a qualified defined contribution plan described in
         Section 401(a) of the Code, the terms of which permit rollover
         contributions, or an annuity plan described in Section 403(a) of the
         Code. If the distributee is the surviving spouse of a Participant and
         is to receive a distribution on account of the Participant's death, an
         eligible retirement plan is an individual retirement account or an
         individual retirement annuity only.

                        AMENDMENTS AND ACTION BY EMPLOYER

11.01    AMENDMENTS

         The Employer reserves the right to make from time to time any amendment
         or amendments to this Plan which do not cause any part of the assets of
         the Plan to be used for, or diverted to, any purpose other than the
         exclusive benefit of Participants or their Beneficiaries; provided,
         however, that the Employer may make any amendment it determines
         necessary or desirable, with or without retroactive effect, to comply
         with the requirements of the Internal Revenue code or of any other
         pertinent provision of Federal or State law, or any regulation or
         ruling of any duty constituted authority in connection therewith.

11.02    ACTION BY EMPLOYER

         Any action by the Employer under this Plan may be made by resolution of
         its Board of Directors, or by any person or persons duly authorized by
         resolution of said Board to take such action.

                                   ARTICLE XII

             SUCCESSOR EMPLOYER AND MERGER OR CONSOLIDATION OF PLANS

12.01    SUCCESSOR EMPLOYER

         In the event of the dissolution, merger, consolidation or
         reorganization of the Employer, provision may be made by which the Plan
         will be continued by the successor; and, in that event, such successor
         shall be substituted for the Employer under the Plan. The substitution
         of the successor shall constitute an assumption of Plan liabilities by
         the successor and the successor shall have all the powers, duties and
         responsibilities of the Employer under the Plan and Trust Agreement.

12.02    PLAN ASSETS

         In the event of any merger or consolidation of the Plan with, or
         transfer in whole or in part of the Trust Fund assets and liabilities
         of the Plan to another plan of deferred compensation maintained or to
         be established for the benefit of all or some of the Participants of
         this Plan, the Trust Fund assets applicable to such Participants shall
         be transferred to the other plan only if:

         (a)      each Participant would (if either this Plan or the other plan
                  then terminated) receive a benefit immediately after the
                  merger, consolidation or transfer which is equal to or greater
                  than the benefit he would have been entitled to receive
                  immediately before the merger, consolidation or transfer (if
                  this Plan had then terminated);

         (b)      resolutions of the Board of Directors of the Employer under
                  this Plan, or of any new or successor employer of the affected
                  Participants, shall authorize such transfer of assets; and, in
                  the case of the new or successor employer of the affected
                  Participants, its resolutions shall include an assumption of
                  liabilities with respect to such Participant's inclusion in
                  the new employer's plan; and

         (c)      such other plan is qualified under Section 401(a) and 501(a)
                  of the Internal Revenue Code.

         Upon any merger or consolidation of the Plan with another plan, or
         transfer of assets and liabilities of the Plan to such other plan, the
         Board of Directors of the Employer may authorize the Plan Administrator
         to allocate immediately prior to the merger, consolidation or transfer
         any amounts then held in a suspense account. If the suspense account
         includes Forfeitures from Profit Sharing Accounts, the suspense account
         shall be allocated among all Participants who have a balance in their
         Profit Sharing Account according to the ratio that the balance of each
         such Participant's Profit Sharing Account bears to the total balance of
         all Participants' Profit Sharing Accounts as of the date of allocation.
         If the suspense account includes Forfeitures from Matching
         Contributions Accounts, the suspense account may be allocated (a) to
         reduce the amount of Matching Contributions then due from the Employer
         for the current Plan Year or (b) among those

                                      -68-

         Participants who have a balance in their 401(k) and Matching
         Contributions Accounts according to the ratio that the aggregate of
         each such Participant's Matching Contributions Account and 401(k)
         Account bears to the total balance of all Participants' 401(k) and
         Matching Contributions Accounts. Allocations under this Section 12.02
         shall be subject to the provisions of Sections 3.09 and 3.10. (1/l/97)

         In accordance with the procedures set forth in this Article, the
         Employer may terminate the Plan at any time. In the event of the
         dissolution, merger, consolidation or reorganization of the Employer,
         the Plan shall terminate and the Trust assets shall be liquidated
         unless the Plan is continued by a successor to the Employer in
         accordance with Section 12.01.

13.02    PARTIAL TERMINATION

         Upon termination of the Plan with respect to a group of Participants
         which constitutes a partial termination of the Plan, the Plan
         Administrator shall allocate and segregate for the benefit of the
         Employees then or theretofore employed by the Employer with respect to
         which the Plan is being terminated the proportionate interest of such
         Participants in the Trust assets. The assets so allocated and
         segregated shall be used by the Plan Administrator to pay benefits to
         or on behalf of Participants in accordance with Section 13.03.

13.03    LIQUIDATION OF THE PLAN

         Upon termination or partial termination of the Plan, the accounts of
         all Participants affected thereby shall become fully vested, and the
         Plan Administrator shall, subject to the provisions of the immediately
         following paragraph, cause the assets remaining in the Trust (including
         any Forfeitures which shall not have been allocated) to be allocated
         and distributed to the remaining Participants and Beneficiaries in
         proportion to their respective account balances.

         In the event that any service charges assessed under this Plan are due
         and unpaid as of such Plan termination date, the payment of such
         charges shall be satisfied by deducting a pro rata share of the amount
         remaining to be paid from each Participant's Profit Sharing Account.

13.04    MANNER OF DISTRIBUTION

         To the extent that no discrimination in value results, any distribution
         after termination of the Plan may be made, in whole or in part, in
         cash, in securities or in nontransferable annuity contracts, as the
         Plan Administrator (in his discretion) may determine. All non-cash
         distributions shall be valued at fair market value at date of
         distribution.

         TRUST AGREEMENT, dated as of the first day of June, 1996, between HADCO
CORPORATION, a Massachusetts corporation, having an office at 12A Manor Parkway,
Salem, New Hampshire 03079 (the "SPONSOR"), and FIDELITY MANAGEMENT TRUST
COMPANY, a Massachusetts trust company, having an office at 82 Devonshire
Street, Boston, Massachusetts 02109 (the "TRUSTEE").

                                   WITNESSETH:

         WHEREAS, the Sponsor is the sponsor of the HADCO Corporation Retirement
Plan (the "PLAN"); and

         WHEREAS, the Sponsor wishes to establish a trust to hold and invest
plan assets under the Plan for the exclusive benefit of participants in the Plan
and their beneficiaries; and

         WHEREAS, the HADCO Corporation Retirement Plan Investment Committee
(the "INVESTMENT COMMITTEE") is the named fiduciary of the Plan (within the
meaning of section 402(a) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA")); and

         WHEREAS, the Trustee is willing to hold and invest the aforesaid plan
assets in trust pursuant to the provisions of this Trust Agreement, which shall
constitute a continuation, by means of an amendment and restatement, of each of
the prior trusts from which plan assets are transferred to the Trustee; and

         WHEREAS, the Trustee is willing to hold and invest the aforesaid plan
assets in trust among several investment options selected by the Investment
Committee; and

         WHEREAS, the Sponsor wishes to have the Trustee perform certain
ministerial recordkeeping and administrative functions under the Plan; and




<PAGE>   5
                                      -2-



         WHEREAS, the HADCO Corporation Retirement Plan Administrative Committee
(the "ADMINISTRATOR") is the administrator of the Plan (within the meaning of
section 3(16)(A) of ERISA); and

         WHEREAS, the Trustee is willing to perform recordkeeping and
administrative services for the Plan if the services are purely ministerial in
nature and are provided within a framework of plan provisions, guidelines and
interpretations conveyed in writing to the Trustee by the Administrator.

         NOW, THEREFORE, in consideration of the foregoing premises and the
mutual covenants and agreements set forth below, the Sponsor and the Trustee
agree as follows:

         Section 1. TRUST. The Sponsor hereby establishes the HADCO Corporation
Retirement Trust (the "TRUST") with the Trustee. The Trust shall consist of an
initial contribution of money or other property acceptable to the Trustee in its
sole discretion, made by the Sponsor or transferred from a previous trustee
under the Plan, such additional sums of money as shall from time to time be
delivered to the Trustee under the Plan, all investments made therewith and
proceeds thereof, and all earnings and profits thereon, less the payments that
are made by the Trustee as provided herein, without distinction between
principal and income. The Trustee hereby accepts the Trust on the terms and
conditions set forth in this Agreement. In accepting this Trust, the Trustee
shall be accountable for the assets received by it, subject to the terms and
conditions of this Agreement.

         Section 2. EXCLUSIVE BENEFIT AND REVERSION OF SPONSOR CONTRIBUTIONS.
Except as provided under applicable law, no part of the Trust may be used for,
or diverted to, purposes other than the exclusive benefit of the participants in
the Plan or their beneficiaries prior to the satisfaction of all liabilities
with respect to the participants and their beneficiaries.

                                      -3-


         Section 3.  DISBURSEMENT.

                  (a) ADMINISTRATOR DIRECTED DISBURSEMENTS. The Trustee shall
make disbursements in the amounts and in the manner that the Administrator
directs from time to time in writing. The Trustee shall have no responsibility
to ascertain such direction's compliance with the terms of the Plan or of any
applicable law or the direction's effect for tax purposes or otherwise; nor
shall the Trustee have any responsibility to see to the application of any
disbursement.

                  (b) PARTICIPANT WITHDRAWAL REQUESTS. The Sponsor hereby
directs that, pursuant to the Plan, a participant withdrawal request (in-service
or full withdrawal) may be made by the participant by telephone, and the Trustee
shall process such request only after the identity of the participant is
verified by use of a personal identification number ("PIN") and social security
number. The Trustee shall process such withdrawal in accordance with written
guidelines provided by the Sponsor and documented in the Plan Administrative
Manual.

                  (c) LIMITATIONS. The Trustee shall not be required to make any
disbursement in excess of the net realizable value of the assets of the Trust at
the time of the disbursement. The Trustee shall not be required to make any
disbursement in cash unless the Administrator has provided a written direction
as to the assets to be converted to cash for the purpose of making the
disbursement.

         Section 4.  INVESTMENT OF TRUST.

                  (a) SELECTION OF INVESTMENT OPTIONS. The Trustee shall have no
responsibility for the selection of investment options under the Trust and shall
not render investment advice to any person in connection with the selection of
such options.




<PAGE>   7
                                      -4-


                  (b) AVAILABLE INVESTMENT OPTIONS. The Investment Committee
shall direct the Trustee as to the investment options: (i) in which the Trust
shall be invested during the participant recordkeeping reconciliation period,
which shall be defined as the period beginning on the date of the initial
transfer of assets to the Trustee and ending on the date of the completion of
the reconciliation of participant records, (ii) in which investment option any
portion of participant's accounts that are not directed by participants are to
be invested, and (iii) in which Plan participants may invest, subject to the
following limitations. The Investment Committee may determine to offer as
investment options only (i) securities issued by the investment companies
advised by Fidelity Management & Research Company ("Mutual Funds"), (ii) equity
securities issued by the Sponsor or an affiliate which are publicly-traded and
which are "qualifying employer securities" within the meaning of section
407(d)(5) of ERISA ("SPONSOR STOCK"), (iii) notes evidencing loans to Plan
participants in accordance with the terms of the Plan, (iv) guaranteed
investment contracts chosen by the Trustee, and (v) collective investment funds
maintained by the Trustee for qualified plans; provided that the Trustee shall
be considered a fiduciary with investment discretion only with respect to Plan
assets that are invested in guaranteed investment contracts chosen by the
Trustee or in collective investment funds maintained by the Trustee for
qualified plans. The investment options initially selected by the Investment
Committee are identified on Schedules "A" and "C" attached hereto. The
Investment Committee may add additional investment options with the consent of
the Trustee and upon mutual amendment of this Trust Agreement and the Schedules
thereto to reflect such additions.

                  (c) PARTICIPANT DIRECTION. Each Plan participant may direct
the Trustee in which investment option(s) to invest the assets in the
participant's individual accounts. Such directions may be made by Plan
participants by use of the telephone exchange system maintained





<PAGE>   8
                                      -5-


for such purposes by the Trustee or its agent, in accordance with written
Telephone Exchange Guidelines attached hereto as Schedule "G". In the event that
the Trustee fails to receive a proper direction, the assets shall be invested in
the investment option set forth for such purpose on Schedule "C", until the
Trustee receives a proper direction.

                  (d) MUTUAL FUNDS. The Sponsor hereby acknowledges that it has
received from the Trustee a copy of the prospectus for each Mutual Fund selected
by the Investment Committee as a Plan investment option or short-term investment
fund. Trust investments in Mutual Funds shall be subject to the following
limitations:

                           (i) EXECUTION OF PURCHASES AND SALES. Purchases and
         sales of Mutual Funds (other than for exchanges) shall be made on the
         date on which the Trustee receives from the Sponsor in good order all
         information and documentation necessary to accurately effect such
         purchases and sales (or in the case of a purchase, the subsequent date
         on which the Trustee has received a wire transfer of funds necessary to
         make such purchase). Exchanges of Mutual Funds shall be made in
         accordance with the Telephone Exchange Guidelines attached hereto as
         Schedule "G".

                           (ii) VOTING. Each Plan participant shall have the
         right to direct the Trustee as to the manner in which the Trustee is to
         vote the shares of any Mutual Funds credited to the participant's
         accounts (both vested and unvested). At the time of mailing of notice
         of each annual or special stockholders' meeting of any Mutual Fund, the
         Trustee shall send a copy of the notice and all proxy solicitation
         materials to each Plan participant who has shares of the Mutual Fund
         credited to the participants accounts, together with a voting direction
         form for return to the Trustee or its designee, and the Trustee shall
         vote the shares as directed by the participant. The Investment
         Committee shall receive a copy




<PAGE>   9
                                      -6-


         of the notice and all proxy solicitation materials for shares of the
         Mutual Fund held in any short-term investment fund or liquidity
         reserve. The Investment Committee shall have the right to direct the
         Trustee as to the manner in which the Trustee is to vote the Mutual
         Fund shares held in any short-term investment fund or liquidity
         reserve, and the Trustee shall vote such shares as directed by the
         Investment Committee. The Trustee shall not vote shares for which it
         has received no directions from the participant or the Investment
         Committee. During the participant recordkeeping reconciliation period,
         the Investment Committee shall have the right to direct the Trustee as
         to the manner in which the Trustee is to vote the shares of the Mutual
         Funds in the Trust including Mutual Fund shares held in any short-term
         investment fund for liquidity reserve. With respect to all rights other
         than the right to vote, the Trustee shall follow the directions of the
         participant and if no such directions are received, the directions of
         the Investment Committee. The Trustee shall have no further duty to
         solicit directions from participants or the Sponsor.

                  (e) NOTES. The Administrator shall act as the Trustee's agent
for the purpose of holding all trust investments in participant loan notes and
related documentation and as such shall: (1) hold physical custody of and keep
safe the notes and other loan documents, (ii) collect and remit all principal
and interest payments to the Trustee and (iii) keep the repayments of such loans
separate from the other assets of the Administrator and clearly identify such
assets as Plan assets and (iv) cancel and surrender the notes and other loan
documentation when a loan has been paid in full. To originate a participant
loan, the Plan participant shall direct the Trustee as to the type of loan to be
made from the participant's individual account. Such directions shall be made by
Plan participants by use of the telephone exchange system maintained for such
purpose by the Trustee or its agent. The Trustee shall determine, based on the
current value of the participant's





<PAGE>   10
                                      -7-


account, the amount available for the loan. Based on the interest rate supplied
by the Administrator in accordance with the terms of the Plan, the Trustee shall
advise the participant of such interest rate, as well as the installment payment
amounts. The Trustee shall forward the loan document and truth-in-lending
disclosures to the participant for execution and submission for approval to the
Administrator. The Administrator shall have the responsibility for approving the
loan and instructing the Trustee to send the loan proceeds to the Administrator
or to the participant if so directed by the Administrator. In all cases, such
instruction by the Administrator shall be made within thirty (30) days of the
participant's initial request (the origination date).

                  (f) GUARANTEED INVESTMENT CONTRACTS. Trust investments in
guaranteed investment contracts ("GICs") shall be subject to the following
limitations:

                           (i) COMMINGLED POOL INVESTMENTS. To the extent that
         the Investment Committee selects as an investment option the Managed
         Income Portfolio of the Fidelity Group Trust for Employee Benefit Plans
         (the "Group Trust"), the Investment Committee hereby (A) agrees to the
         terms of the Group Trust and adopts said terms as a part of this
         Agreement and (B) acknowledges that it has received from the Trustee a
         copy of the Group Trust, the Declaration of Separate Fund for the
         Managed Income Portfolio of the Group Trust, and the Circular for the
         Managed Income Portfolio.

                           (ii) In order to provide the necessary monies for
         exchanges or redemptions from the GIC investment option, if any, under
         the Plan, the Investment Committee agrees that the Plan shall maintain
         a liquidity reserve allocated to the Plan GIC investment option in
         Fidelity Institutional Cash Portfolios: Money Market Portfolio: Class A
         or such other Mutual Fund or commingled money market pool as agreed to
         by the Investment Committee and the Trustee.

                  (g) RELIANCE OF TRUSTEE ON DIRECTIONS.

                           (i) The Trustee shall not be liable for any loss, or
         by reason of any breach, which arises from any participant's exercise
         or non-exercise of rights under this Section 4 over the assets in the
         participant's accounts.

                           (ii) The Trustee shall not be liable for any loss, or
         by reason of any breach, which arises from the Investment Committee's
         exercise or non-exercise of rights under this Section 4, unless it was
         clear on their face that the actions to be taken under the Investment
         Committee's directions were prohibited by the fiduciary duty rules of
         Section 404(a) of ERISA or were contrary to the terms of the Plan or
         this Agreement.

                  (h) TRUSTEE POWERS. The Trustee shall have the following
powers and authority:


                           (i) Subject to paragraphs (b), (c), (d) and (e) of
         this Section 4, to sell, exchange, convey, transfer, or otherwise
         dispose of any property held in the Trust, by private contract or at
         public auction. No person dealing with the Trustee shall be bound to
         see to the application of the purchase money or other property
         delivered to the Trustee or to inquire into the validity, expediency,
         or propriety of any such sale or other disposition.

                           (ii) Subject to paragraphs (b) and (c) of this
         Section 4, to invest in guaranteed investment contracts and short term
         investments (including interest bearing accounts with the Trustee or
         money market mutual funds advised by affiliates of the Trustee) and in
         collective investment funds maintained by the Trustee for qualified
         plans, in which case the provisions of each collective investment fund
         in which the Trust is invested shall be deemed adopted by the Sponsor
         and the provisions thereof incorporated



<PAGE>   12
                                      -9-


         as a part of this Trust as long as the fund remains exempt from
         taxation under Sections 401(a) and 501(a) of the Internal Revenue Code
         of 1986, as amended.

                           (iii) To cause any securities or other property held
         as part of the Trust to be registered in the Trustee's own name, in the
         name of one or more of its nominees, or in the Trustee's account with
         the Depository Trust Company of New York and to hold any investments in
         bearer form, but the books and records of the Trustee shall at all
         times show that all such investments are part of the Trust.

                           (iv) To keep that portion of the Trust in cash or
         cash balances as the Investment Committee or Administrator may, from

                 (a) GENERAL. The Trustee shall perform those recordkeeping and
administrative functions described in Schedule "A" attached hereto. These
recordkeeping and administrative functions shall be performed within the
framework of the Administrator's written directions regarding the Plan's
provisions, guidelines and interpretations.

                  (b) ACCOUNTS. The Trustee shall keep accurate accounts of all
investments, receipts, disbursements, and other transactions hereunder, and
shall report the value of the assets held in tile Trust as of the last day of
each fiscal quarter of the Plan and, if not on the last day of a fiscal quarter,
the date on which the Trustee resigns or is removed as provided in Section 8 of
this Agreement or is terminated as provided in Section 10 (the "Reporting
Date"). Within thirty (30) days following each Reporting Date or within sixty

of the Trustee, or the termination of this Agreement, the Trustee shall file
with the Administrator a written account setting forth all investments,
receipts, disbursements, and other transactions effected by the Trustee between

or the termination of this Agreement, the Trustee shall provide to the
Administrator, at no expense to the Sponsor, in the format regularly provided to
the Administrator, a statement of each participant's accounts as of the
resignation, removal, or termination, and the Trustee shall provide to the

to time, the Sponsor shall send to the Trustee a payment in such amount or the
Sponsor may direct the Trustee to deduct such amount from participants' accounts
and any unallocated portion of the Trust fund on a pro rata basis. All expenses
of the Trustee relating directly to the acquisition and disposition of
investments constituting part of the Trust, and all taxes of any kind whatsoever
that may be levied or assessed under existing or future laws upon or in respect
of the Trust or the income thereof, shall be a charge against and paid from the

Plan or this Agreement.

                  (c) DIRECTIONS FROM INVESTMENT COMMITTEE. Whenever the

                   THIRD AMENDMENT TO TRUST AGREEMENT BETWEEN
                      FIDELITY MANAGEMENT TRUST COMPANY AND
                                HADCO CORPORATION


         THIS THIRD AMENDMENT, dated as of the first day of January, 1998, by
and between Fidelity Management Trust Company (the "Trustee") and Hadco
Corporation (the "Sponsor");

                                   WITNESSETH:

         WHEREAS, the Trustee and the Sponsor heretofore entered into a Trust
Agreement dated June 1, 1996, with regard to the Hadco Corporation Retirement
Plan (the "Plan"); and

         WHEREAS, the Trustee and the Sponsor now desire to amend said Trust
Agreement as provided for in Section 13 thereof,

         NOW THEREFORE, in consideration of the above premises the Trustee and
the Sponsor hereby amend the Trust Agreement by:

         (1)      Amending Section 4(e) by restating as follows:

                  (e)      NOTES.

                  (i)      NOTES ON CONTRIBUTIONS TO THE HADCO CORPORATION
                  RETIREMENT PLAN BEFORE JULY 1, 1996 AND ON CONTRIBUTIONS TO
                  THE ZYCON CORPORATION PROFIT SHARING 401(K) PLAN BEFORE
                  OCTOBER 1, 1997. The Administrator shall act as the Trustee's
                  agent for the purpose of holding all trust investments in
                  participant loan notes and related documentation and as such
                  shall (i) hold physical custody of and keep safe the notes and
                  other loan documents, (ii) separately account for repayments
                  of such loans and clearly identify such assets as Plan assets,
                  (iii) collect and remit all principal and interest payments to
                  the Trustee, and (iv) cancel and surrender the notes and other
                  loan documentation when a loan has been paid in full. To
                  originate a participant loan, the Plan participant shall
                  direct the Trustee as to the type of loan to be made from the
                  participant's individual account. Such directions shall be
                  made by Plan participants by use of the telephone exchange
                  system maintained for such purpose by the Trustee or its
                  agent. The Trustee shall determine, based on the current value
                  of the participants account, the amount available for the
                  loan. Based on the interest rate supplied by the Sponsor in
                  accordance with the terms of the Plan, the Trustee shall
                  advise the participant of such interest rate, as well as the
                  installment payment amounts. The Trustee shall forward the
                  loan document to the participant for execution and submission
                  for approval to the Administrator. The Administrator shall
                  have the responsibility for approving the loan and instructing
                  the Trustee to send the loan proceeds to the Administrator or
                  to the participant if so directed by the Administrator. In all
                  cases, approval or disapproval by the Administrator shall be
                  made within thirty (30) days of the participant's initial
                  request (the origination date).

                  (ii)     NOTES ON ALL OTHER CONTRIBUTIONS. The Administrator
                  shall act as the Trustee's agent for participant loan notes
                  and as such shall (i) separately account for repayments of
                  such loans and clearly identify such assets as Plan assets and
                  (ii) collect and remit all principal and interest payments to
                  the Trustee. To originate a participant loan, tile Plan
                  participant shall direct the Trustee as to the term and amount
                  of the loan to be made from the participant's individual
                  account. Such directions shall be made by Plan participants by
                  use of the telephone exchange system maintained for such
                  purpose by the Trustee or its agent. The Trustee shall
                  determine, based on the current value of the participant's
                  account on the date of the request and any guidelines provided
                  by the Sponsor, the amount available for the loan. Based on
                  the interest rate supplied by the Sponsor in accordance with
                  the terms of the Plan, the Trustee shall advise the
                  participant of such interest rate, as well as the installment
                  payment amounts. The Trustee shall distribute the Participant
                  loan agreement and truth-in-lending disclosure with the
                  proceeds check to the participant. To facilitate
                  recordkeeping, the Trustee may destroy the original of any
                  promissory note made in connection with a loan to a
                  participant under the Plan, provided that the Trustee first
                  creates a duplicate by a photographic or optical scanning or
                  other process yielding a reasonable facsimile of the
                  promissory note and the Plan participant's signature thereon,
                  which duplicate may be reduced or enlarged in size from the
                  actual size of the original promissory note.

         IN WITNESS WHEREOF, the Trustee and the Sponsor have caused this third
Amendment to be executed by their duly authorized officers effective as of the
day and year first above written.
