                                     PART I
 
ITEM 1.  BUSINESS
 
GENERAL
 
     Hadco Corporation (the "Company" or "HADCO") is a leading independent
manufacturer of high density double-sided and complex multilayer printed
circuits and backplane assemblies used in the computer, telecommunications and
industrial automation industries, including process control systems, automotive
electronics and electronic instrumentation. The Company's customers include
large, medium and small original equipment manufacturers ("OEM") of electronic
systems, as well as independent sub-contract manufacturers. HADCO is a
Massachusetts corporation organized in 1966. The Company is headquartered in
Salem, New Hampshire and operates facilities in New Hampshire, New York and
California.
 
INDUSTRY OVERVIEW
 
     HADCO's business is the provision of electronic interconnect solutions,
primarily printed circuits and backplane assemblies. Printed circuits are the
base used to interconnect the microprocessors, integrated circuits, capacitors,
resistors, and other components critical to the operation of electronic
equipment. Printed circuits are generally made of rigid fiberglass, rigid paper
or thin flexible plastic. The Company manufactures primarily rigid fiberglass
printed circuits. Backplanes ("value added assemblies") are printed circuits on
which connectors are mounted to receive and interconnect printed circuits,
integrated circuits and other electronic components.
 
     In recent years, the trend in the electronics industry has generally been
toward increasing the speed and performance of components, while reducing their
size. This advancement in component technology has driven the change in printed
circuit design to higher density printed circuits. Surface Mount Technology
("SMT") and multilayer circuits provide some of the solutions to these density
requirements. Within SMT technology, new component attachment methods have been
developed. Tape Automate Bonding (TAB), Ball Grid Array (BGA) and other
component attachment technologies provide electronic equipment producers with a
more cost effective solution to attaching components to a printed circuit. These
attachment strategies continue to drive increased density in printed circuit
design and production. HADCO has invested in the advanced engineering systems
and process equipment needed to meet these density requirements.
 
     The increased technology requirements and high cost of development and
advancement within the printed circuit industry have created a trend toward
turning the OEM away from internal circuit board production, and towards
independent board producers that can effectively manage the high cost of printed
circuit development and advancement. Based on industry sources, the domestic
market for all printed circuits in 1996 was approximately $7.4 billion. Industry
analysts estimate that in 1996, approximately 86% of the domestic printed
circuit market was served by independent manufacturers such as HADCO, with the
remaining 14% being served by captive manufacturing facilities operated by
certain OEMs.
 
DEFINITION OF PRODUCTS AND SERVICES
 
     The Company provides products and services to meet the multilayer and high
density needs of its customers. In fiscal 1996, approximately 79% of the
Company's printed circuit net sales were for high density products with two or
three conductive tracks between plated through-holes with centers 100 mils
apart, as
 
                                        1
<PAGE>   3
 
compared to 67% in 1995 and 63% in 1994. Net sales of multilayer, as opposed to
double sided, printed circuits accounted for 97%, 94%, and 93% of the Company's
printed circuit net sales in fiscal 1996, 1995 and 1994, respectively.
 
     In order to fully support the needs of the Company's customers, HADCO
offers a number of complementary processes and capabilities that span the period
of product conception through delivery to the customer.
 
     The Company supports its customers in the computer aided design for the
physical design and layout of printed circuits. The Company cooperates with
customers in the design of their products in order to assure that their design
specifications will be compatible with the Company's manufacturing processes.
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 on time to customer premises. These results
are important benefits to the Company's customers since many of their products
have increasingly shorter economic lives.
 
     The Company offers solutions to support customer needs in the prototyping
product development stage or small volume production through its Tech Center
facilities in New Hampshire and California. Prototype development at these
facilities has included: embedded discrete components, multilayer boards of up
to 38 layers, Multichip Modules (MCM-L), Single Chip Carriers (SCC), planar
magnetics, advanced surface finishes and various high performance substrates,
which support the high frequency microwave market. The Tech Centers also support
new attachment strategies such as Tape Automated Bonding (TAB), Chip-on-Board
(COB), Flip Chip and Direct Chip Attach (DCA). In combining the design of a
printed circuit with manufacturing of the prototype, HADCO has reduced the
length of design/manufacture cycle. By working with customers at the design and
prototype stage, management believes that the Company has a greater likelihood
of securing a preferred vendor status when customers begin commercial
manufacturing of new products.
 
     The Company operates two facilities, located in New York and New Hampshire,
designed to support medium and high volume printed circuit production. Customers
often demand a quick transition from prototype to volume production. Creating an
effective product development transition from prototype to volume production is
a difficult challenge in today's market. While many competitors can supply
prototypes, as HADCO does through its Tech Centers, relatively few independent
manufacturers can provide complex multilayer printed circuits in the volume that
HADCO's larger facilities can provide. During 1996, the Tech Centers effectively
transitioned chip attachment technologies such as Ball Grid Array (BGA) and
other technologies including Multichip Modules (MCM-L) and single Chip Carriers
(SCC) to volume production. At the same time, volume manufacturing expanded
production space in Derry, N.H. by 34,000 square feet and in Owego, N.Y. by
16,000 square feet, in order to accommodate higher capacities, broader product
offerings and higher layer count.
 
     The Value Added Manufacturing division of HADCO directly supports customers
in the backplane, card cage, and sub-system assembly markets. During 1996, the
Value Added Manufacturing division expanded production space from 40,000 to
60,000 square feet, and added two additional SMT lines, in-circuit tester
capability, and numerous pieces of assembly equipment in order to meet rapidly
growing customer requirements. The Company believes that its Value Added
Manufacturing division provides its customers with a strategic advantage by
offering fully integrated, high quality manufacturing services from prototype,
printed circuit production to backplane assembly.
 
MARKETS AND MARKETING
 
     The Company's strategy is to broaden and diversify the market it serves.
The Company supplies printed circuits and value added assemblies to a diverse
customer base in the computer, telecommunications, instrumentation, including
medical and industrial automation, and automotive industries. Contract assembly,
referenced in the table below, represents a segment which may encompass several
different industries. Within the computer segment, the Company's customers
include leaders in the notebook, advanced peripheral devices and workstation
markets as well as leaders in the minicomputer, mainframe and networking
markets.

     The following table shows, for the periods indicated, the Company's printed
circuit and value added assembly net sales and percentage of its net sales to
the principal end-user markets it serves. Net sales of printed circuits
accounted for 94%, 93% and 83% of total Company net sales during fiscal 1994,
1995 and 1996, respectively; the remaining 6%, 7% and 17%, respectively, were
net sales of value added assembly.

</TABLE>
 
     The Company's high percentage of net sales to the computer industry
reflects the fact that dense multilayer printed circuits are routinely used in
products such as computer workstations, computer peripheral equipment and
networking equipment such as servers, hubs and routers. Consumer products
generally incorporate low-density double-sided boards. The Company does not
manufacture printed circuits of this type.
 
     HADCO has an Advanced Packaging Development Group, whose purpose is to
identify, develop and market new technologies that are highly beneficial to our
customers and position HADCO as a unique source for these solutions. Process
design changes and refinements required for volume production are identified and
implemented prior to production of the orders. Many times this development is
done with customers and alliance partners to ensure accurate and timely results.
The group focuses on the continued densification of electronic packaging, as
well as the evaluation of new high performance materials. When appropriate, the
group has coordinated the acquisition of technology licenses, and filed patent
disclosures and applications, as well as registered Company trademarks. The
group also assists in marketing efforts by hosting the Regional Technology
Symposiums, which present HADCO technical capabilities and industry technical
trends to customers.
 
     HADCO's comprehensive product offerings are a key marketing strategy for
the Company. By offering a full spectrum of integrated processes and
capabilities including printed circuit design assistance, prototype and
preproduction fabrication, medium and high volume fabrication, as well as value
added assembly, HADCO can help its customers cut time-to-market schedules. In
addition, by working with products from the design stage, HADCO can enhance the
manufacturability during volume production.
 
     The Company markets its products through its own sales and marketing
organization and independent manufacturers' representatives. As of October 26,
1996, the Company employed 91 sales and marketing employees, of which 36 are
direct sales representatives at 8 locations. The Company is also represented by
14 independent manufacturers' representatives at 22 locations in North America,
Europe, Mexico, Asia, Australia and the Middle East. Regional direct sales
offices are located in the states of California, Georgia, Minnesota, New
Hampshire, Pennsylvania, Arizona and Texas, and the Province of Ontario, Canada.
The Company's marketing organization consists of a vice president in charge of
sales and marketing, 9 regional sales managers, a support staff of sales
engineers and technical service personnel responsible for technical liaison and
problem solving, development of product and market opportunities, market
research and marketing communications.
 
     The Company currently exports a small percentage of its products.

CUSTOMERS
 
     The Company supplied more than 410 customers during fiscal 1996, and 382
customers in fiscal 1995. The Company attempts to market its products to
customers who currently have or have the potential to obtain significant market
shares in their respective industries. The following list sets forth the
Company's largest customers during fiscal 1996:
 
<TABLE>
     <S>                                                        <C>

     Northern Telecom, Inc.                                     Sun Microsystems, Inc.
</TABLE>
 
     During fiscal 1996, 1995 and 1994, no customer accounted for more than 15%,
7% and 7%, respectively, of HADCO's consolidated net sales. The Company's five
largest customers accounted for 33%, 28% and 28% of HADCO's consolidated net
sales during fiscal 1996, 1995 and 1994, respectively. In 1996 only one
customer, Sun MicroSystems, Inc., accounted for more than 10% of HADCO's
consolidated net sales.
 
     HADCO continues its efforts to decrease its dependence upon the computer
market by seeking new customers in different markets, particularly those that
require complex state-of-the-art printed circuits or whose needs closely match
the capabilities of the Company.
 
MANUFACTURING
 
     Three processes are used in the United States to manufacture electronic
interconnect circuits. In the subtractive process, the conductive paths are
formed by etching copper from the laminated board. In the additive process,
conductive lines are formed by an electroless deposition of copper onto the
board. In the discrete wiring process, patterns of insulated copper wire are
laid down by numerically controlled machines. The subtractive process is the
most common process used in the production of printed circuits made in the
United States. HADCO exclusively uses the subtractive process to manufacture
high density multilayer and double-sided rigid fiberglass printed circuits.
 
     The need for high volume production of dense multilayer and double-sided
printed circuits has transformed HADCO's segment of the electrical interconnect
industry into one that increasingly requires complex manufacturing processes,
necessitating high levels of capital investment and high technology materials,
production processes and product design capabilities. The Company has invested
in the production technology to manufacture large volumes of dense multilayer
printed circuits utilizing surface mount technology. The Company employs
numerous advanced manufacturing techniques and systems which include: Computer
Aided Manufacturing (CAM) systems, Computer Integrated Manufacturing (CIM)
systems, computer controlled drilling and routing, dry-film imaging,
multi-purpose metals plating, high volume surface coating, dual access
electrical testing, automated optical inspection, high volume photoimageable
solder mask processing, and computer controlled high volume lamination systems.
These techniques enable HADCO to manufacture complex printed circuits of
consistent quality in high volume on a timely basis. All of the Company's
production facilities are ISO9002 certified.
 
SUPPLIER RELATIONSHIPS
 
     Historically, the majority of raw materials used in the manufacture of the
Company's products have been readily available. However, as product changes
increase the industry's use of new laminate materials, and drive up average
layer count, the potential for shortages in the supply of laminates, multilayer
blanks, and other materials increases. To date, material shortages or price
fluctuations have not had a materially adverse effect on the Company, but there
can be no assurance that material shortages or price fluctuations will not have
a material adverse effect on the Company in the future.
 
     The Company works extensively 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 quality, on-time delivery, cost, technical capability and potential technical
advancement and other factors. 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
 
                                        4
<PAGE>   6
 
and have regular dialogue on quality, cost and technical advancement issues.
Many suppliers attend the Company Supplier Symposium, where goals and objectives
for the Company are shared with vendors.
 
COMPETITION
 
     The domestic market for printed circuits is highly competitive and
fragmented. HADCO believes its major competitors are the larger independent
producers and captive producers world-wide, which also manufacture multilayer,
high density printed circuits. Many of the captives are part of large national
or multi-national companies. The major captive printed circuit producers include
IBM and other large electronic equipment manufacturers. During periods of
recession in the electronics industry, any competitive advantages of the Company
in the areas of quick turn-around manufacturing, responsive customer service,
and new product offerings may be of reduced importance to electronics OEMs, who
may become more price sensitive. In addition, captive interconnect product
manufacturers may seek orders in the open market to fill excess capacity,
thereby increasing price competition.
 
     The number of companies engaged in the volume production of high density,
multilayer printed circuits is considerably smaller than the number of companies
manufacturing other types of printed circuits. High density multilayer boards
involve a high level of material and process technology, and therefore, are more
complex to manufacture than less complex printed circuits.
 
     The demand for printed circuits has continued to be partially offset,
during the past several years, by the development of smaller, more powerful
electronic components requiring less printed circuit board area. The Company
continues to emphasize high density multilayer circuits, particularly surface
mount applications that support smaller, more powerful electronic components.
 
     HADCO competes on the basis of product quality, timeliness of delivery,
price, customer technical support and the capability to produce complex circuits
in prototype, preproduction and high volume.
 
PRODUCT PROTECTION
 
     The Company seeks to protect certain proprietary technology and other
intangible assets through patents and trademark filings. However, 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 important to its operation.
 
BACKLOG
 
     As of October 26, 1996, the Company's released backlog was $77.7 million,
as compared with $70.5 million as of October 28, 1995. The Company anticipates
manufacturing and delivering approximately 86% of such backlog during the first
quarter of fiscal 1997. The Company's business is not seasonal. Released backlog
consists of orders for which artwork has been received, a delivery date has been
scheduled and the Company anticipates that it will manufacture and deliver the
order. Cancellation and postponement charges, to the extent they exist with
respect to backlog, generally vary depending upon the time of cancellation or
postponement, and a certain portion of the Company's backlog may be subject to
cancellation or postponement without significant penalty or without any penalty.
The table below shows the released backlog of the Company in millions of dollars
at the end of each of the past five quarters:

EMPLOYEES
 
     The Company believes that its employee relations are excellent. The
employees are not represented by a union, and the Company has never experienced
any labor problems resulting in a work stoppage. As of October 26, 1996, the
Company had 3,005 employees, as compared to 2,346 as of October 28, 1995.
 
ENVIRONMENTAL
 
     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.
The Company believes that the resolution of these matters will not have a
material adverse effect on the Company. 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 recently executed a
Modification of the Order on Consent to implement the approved ROD. The cost,
based upon the FFS, to implement this remediation is estimated to be $4.6
million, and is expected to be expended as follows: $260,000 for capital
equipment and $4.3 million for operation and maintenance costs which will be
incurred and expended over the estimated life of the program of 30 years. NYSDEC
has requested that the Company consider taking additional samples from a wetland
area near the Company's Owego facility. Analytical reports of earlier sediment
samples indicated the presence of certain inorganics. 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
second sentence of the penultimate paragraph of this "Environmental" section.
 
     From 1974 to 1980, the Company operated a printed circuit manufacturing
facility in Florida as a lessee of property that is now the subject of a pending
lawsuit ("the Florida Lawsuit") and investigation by the Florida Department of
Environmental Regulation (FDER). On June 9, 1992, the Company entered into a
Cooperating Parties Agreement in which it and Gould, Inc., another prior lessee
of the site have agreed to fund certain assessment and feasibility study
activities at the site, and an environmental consultant has been retained to
perform such activities. The cost of such activities is not expected to be
material to the Company. In addition to the Cooperating Parties Agreement, Hadco
and others are participating in alternative dispute resolution regarding the
site with an independent mediator. In connection with the mediation, in February
1992 the FDER presented computer-generated estimates of remedial costs, for
activities expected to be spread over a number of years, that ranged from
approximately $3.3 million to $9.7 million. Mediation sessions were conducted in
March 1992 but have been suspended during the ongoing assessment and feasibility
activities. Management believes it is likely that it will participate in
implementing a continuing remedial program for the site, the costs of which are
currently unknown. However, based on information currently known by the Company,
management does not expect these costs to have a material adverse effect on the
Company. In June 1995, Hadco was named a third-party defendant in the Florida
Lawsuit. See Item 3, "Legal Proceedings," for information relating to this
lawsuit.
 
     The Company has commenced the operation of a groundwater extraction system
at its Derry, New Hampshire facility to address certain groundwater
contamination and groundwater migration control issues. 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
 
                                        6
<PAGE>   8
 
conducting any additional investigations and remediation relating to the Derry
facility are not fully determinable due to the numerous variables described in
the penultimate paragraph of this "Environmental" section.
 
     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 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 Results of Operations and Financial
Condition," and footnote 7 of Notes to Consolidated Financial Statements.
 
     The Company does plan further capital expenditures during fiscal 1997 to
further reduce air emissions and reduce waste generation. See discussion under
Item 2, "Properties," concerning the Company's capital expenditures for
environmental control facilities. Also see Item 3, "Legal Proceedings," relating
to lawsuits regarding environmental matters.

expires in 1999, with an option of the Company to extend until 2004. The Hudson
operation is located in two separate facilities. Both leases expire in 1997 with
options to extend until 2000. The Watsonville lease runs until December 1996 and
has one three-year option remaining.
 
     The Company owns approximately 6 acres of land in Salem, New Hampshire,
approximately 5 acres of land in Derry, New Hampshire, and approximately 10
acres in Owego, New York, which could be used for future expansion.
 
     In fiscal 1996, the Company's capital expenditures relating to its
environmental control facilities and equipment totaled approximately $904,000.
The Company estimates that it will make capital expenditures with respect to its
environmental control facilities and equipment of approximately $750,000 and
$500,000 in fiscal 1997 and 1998, respectively.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     The Company is one of thirty-three 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 April, 1996, the EPA published for comment, and
recommended for approval, a proposal to change the remedy at the Auburn Road
site from active groundwater remediation to future monitoring. Other parties to
the lawsuit also allege that future monitoring will be required. The Company is
contesting liability, but is participating in mediation with twenty-seven other
parties in an effort to resolve the lawsuit. Management believes that the
ultimate disposition of this lawsuit will not
 
                                        8
<PAGE>   10
 
have a material adverse effect upon the liquidity, capital resources, business
or consolidated financial position of the Company.
 
     In connection with the "Florida Lawsuit" (as described in the second
paragraph under "Environmental" above) pending in the Circuit Court for Broward
County, Florida, Hadco and Gould, Inc., another prior lessee of the site of the
printed circuit manufacturing facility in Florida, each was served with a
third-party complaint in June 1995, as third-party defendants in such pending
Florida Lawsuit by a party who had previously been named as a defendant when the
Florida Lawsuit was commenced in 1993 by the FDER. The Florida Lawsuit seeks
damages relating to environmental pollution and FDER costs and expenses, civil
penalties, and declaratory and injunctive relief to require the parties to
complete assessment and remediation of soil and ground water contamination. The
other parties include alleged owners of the property.
 
     The future costs in connection with the lawsuits described in the two
immediately preceding 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.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
     No matters were submitted to a vote to the Company's security holders

within the discretion of the Company's Board of Directors, which will review
such dividend policy from time to time. The Company's lines of credit currently
contain certain cash flow requirements that may have the effect of limiting the
Company's ability to pay dividends in the future. See Note 5 of Notes to

Years Ended October 26, 1996 and October 28, 1995
 
   
     Net sales during 1996 increased 32.3% over the same period in 1995. The
change was due to a 15.1% increase in the volume of production and shipments and
a shift in product mix to higher layer, higher density products, as compared to
fiscal 1995. Average pricing per unit increased 6.1% compared to the same period
a year ago. Sales of backplane and other electronic assemblies increased to 17%
of the Company's net sales in 1996, versus 7% for 1995. The Company believes
that excess capacity may exist in the printed circuit and
    
 
                                       10

electronic assembly industries, as well as fluctuating growth rates in the
electronics industry as a whole. Both factors could have an adverse impact on
future orders and pricing. Despite these beliefs regarding the electronics
industry as a whole, it should be noted that the Company has historically needed
to increase its own manufacturing capacity to maintain and expand its market
position. However, the Company's manufacturing capacity needs could change at
any time or times in the future.
    
 
   
     The gross profit margin increased from 25.4% in 1995 to 25.8% in 1996. The
increase is a direct result of higher volume of shipments, an increase in the
technology level of product mix, and improved pricing. These increases have been
partially offset by increased costs relating to the implementation of new
production lines and materials and the shift in mix to a higher level of
value-added products. The Company believes that the potential exists for the
shortage of materials in the industry, which could have an adverse impact on
future unit costs. In response to such concerns, the Company engages in the
normal industry practices of maintaining primary and secondary vendors and
diversifying its customer base. There can be no assurances, however, that such
measures would be sufficient to protect the Company against any shortages of
materials.
    
 
   
     Operating expenses, as a percent of net sales, decreased to 11.1% during
1996 from 12.6% during 1995, due to increased revenue. Operating expenses
increased to $38.9 million in 1996 from $33.5 million in 1995, primarily as a
result of increased variable costs directly attributable to increased net sales.
Included in operating expenses are charges for actual expenditures and accruals,
based on estimates, for environmental matters. During 1996 and 1995, the Company
made, and charged to operating expenses, actual payments of approximately
$680,000 and $1,111,000 respectively, for environmental matters. In 1996 and
1995, the Company also accrued and charged to operating expenses approximately
$1,825,000 and $2,740,000, respectively, as cost estimates relating to known
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 environmental matters. Management 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. See Item 1, "Environmental," Item 3,
"Legal Proceedings," and footnote 7 of Notes to Consolidated Financial
Statements.
    
 
     In 1996, interest income decreased as a result of lower cash balances
available for investment. Interest expense decreased in 1996 from 1995 due to
decreased average debt balances during the year.
 
     The annual effective tax for 1996 and 1995 was 39%, which is less than the
current combined federal and state statutory rates. This difference is caused
primarily by tax advantaged investments and the tax benefits of a foreign sales
corporation.
 
Years Ended October 28, 1995 and October 29, 1994
 
     Net sales during 1995 increased 19.7% over the same period in 1994. The
change was due to an 8.2% increase in the volume of production and shipments and
a shift in product mix to higher layer, higher density products, as compared to
fiscal 1994. Average pricing per unit increased 3.1% compared to the same period
a year ago.
 
   
     The gross profit margin increased from 20.5% in 1994 to 25.4% in 1995. The
increase is a direct result of higher volume of shipments, an increase in the
technology level of product mix, improved pricing and improvements in operating
efficiencies. Continued productivity improvements led to increased unit volume
and lower unit costs.
    
 
   
     Operating expenses, as a percent of net sales, decreased to 12.6% during
1995 from 13.1% during 1994, due to increased revenue. Operating expenses
increased to $33.5 million in 1995 from $29.0 million in 1994, as a result of
increased variable costs directly attributable to increased net sales and
charges for environmental related matters. Included in operating expenses are
charges for actual expenditures and accruals, based on estimates, for
environmental matters. During 1995 and 1994, the Company made, and charged to
operating expenses, actual payments of approximately $1,111,000 and $1,040,000,
respectively, for environmental matters. In 1995 and 1994, the Company also
accrued and charged to operating expenses approximately $2,740,000 and
$2,100,000, respectively, as cost estimates relating to known environmental
matters.

     In 1995, interest income increased as a result of higher rates of return
earned on investments, and higher cash balances available for investment.
Interest expense decreased in 1995 from 1994 due to decreased average debt
balances during the year.
 
     The annual effective tax rate was 39% and 39.5% in 1995 and 1994,
respectively, which was less than the current combined federal and state
statutory rates. This difference was caused primarily by tax advantaged
investments and the tax benefits of a foreign sales corporation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In 1996, the Company's financing requirements were satisfied principally
from cash flows from operations. These funds were sufficient to meet increased
working capital needs, capital expenditures amounting to approximately $54.0
million and debt and lease payments of approximately $2.1 million.
 
     At October 26, 1996, the Company had working capital of $43,561,000 and a
current ratio of 1.62 compared to working capital of $41,043,000 and a current
ratio of 1.78 at October 28, 1995. Cash, cash equivalents and short-term
investments at October 26, 1996 were $42,187,000, an increase of $5,713,000 from
$36,474,000 at October 28, 1995.
 
     At October 26, 1996, the Company had available a credit line of $15,000,000
under its unsecured revolving credit and term loan agreement with a bank. The
unused portion of this credit line at October 26, 1996 was $15,000,000.
 
     At October 26, 1996, the Company also had a lease line of credit of
$5,000,000. The unused portion of this line of credit at October 26, 1996 was
$4,759,000.
 
     The Company has commitments to purchase approximately $10,690,000 of
manufacturing equipment. The majority of these commitments are expected to be
completed by the end of fiscal 1997.
 
     In January 1997, the Company obtained a senior revolving credit loan
facility for up to $250 million from The First National Bank of Boston (the
"Credit Facility") (i) to finance the purchase of the shares of Common Stock of
Zycon Corporation ("Zycon") pursuant to the tender offer commenced by the
Company on December 11, 1996, and (ii) to refinance Zycon's existing bank credit
agreements, and (iii) for working capital and other general corporate purposes.
Loans under the Credit Facility will bear interest (at the Company's election)
at either (1) a Base Rate, which is a floating rate equal to 1 1/2% over the
prevailing U.S. federal funds rate or (2) a Eurodollar Rate, which is a fixed
rate equal to the prevailing Eurodollar rate for interest periods of one, two,
three or six months. The Credit Facility will terminate in 5 years. It is
presently anticipated that funds borrowed would be repaid from internally
generated funds of the Company and Zycon or with the proceeds of subsequent
issuances of equity, debt securities or convertible debt securities. The Credit
Facility terminates the above-referenced $15,000,000 credit line with a bank.
 
     The Company believes its existing working capital and 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 in fiscal 1997.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
     The Company operates in a changing environment that involves a number of
risks, some of which are beyond the Company's control. The following discussion
highlights some of these risks.
 
     VARIABILITY OF CUSTOMER REQUIREMENTS; NATURE AND EXTENT OF CUSTOMER
COMMITMENTS ON ORDERS.  The level and timing of orders placed by the Company's
customers vary due to customer attempts to manage inventory, changes in the
customers' manufacturing strategies and variation in demand for customer
products due to, among other things, technological change, introduction of new
product life cycles, competitive conditions or general economic conditions. The
Company generally does not obtain long-term purchase orders or commitments. A
certain portion of the Company's backlog may be subject to cancellation or
postponement without significant penalty or without any penalty.
 
                                       12
<PAGE>   14
 
     COMPETITION.  The domestic market for printed circuits is highly
competitive and fragmented. The Company believes its major competitors are
larger independent producers and captive producers world-wide, which also
manufacture multilayer, high density printed circuits and provide backplane and
other electronic assemblies. During periods of recession in the electronic
industry, and other periods when excess capacity exists, electronic equipment
manufacturers become more price sensitive, which could have a material adverse
impact on pricing. In addition, the Company's competitors may seek orders in the
open market to fill excess capacity, thereby increasing price competition.
 
     PROCESS TECHNOLOGY AND RISK OF PROCESS FAILURE.  The Company's success
depends in part on its proprietary techniques and manufacturing expertise,
particularly in the area of the multilayer, high density circuit boards. At this
time, the Company has no patents for these proprietary techniques and chooses to
rely on trade secret protection. In addition, the introduction of new
manufacturing processes are subject to failure. The loss of revenue and earnings
to the Company from such a failure could have a material adverse effect on its
results of operations.
 
     DEPENDENCE ON ELECTRONICS INDUSTRY.  The Company's customers include OEMs
and contract manufacturers of data communications and telecommunications
equipment, instrumentation and industrial equipment, and computers and
peripheral business systems. These industry segments, as well as the electronics
industry as a whole, are subject to rapid technological change and product
obsolescence. Discontinuance or modification of products containing printed
circuit boards manufactured by the Company could have a material adverse effect
on the Company. The electronics industry is subject to economic cycles and has
experienced, and is likely in the future to experience, recessionary periods.
Pricing pressures, a general recession or any other event leading to excess
capacity or a down turn in the electronics industry would likely result in
intensified price competition, reduced gross margins and a decrease in unit
volume, which could have a material adverse effect on the Company.
 
     ENVIRONMENTAL COMPLIANCE.  The Company is subject to a variety of
environmental regulations relating to the use, storage, discharge and disposal
of hazardous chemicals used during its manufacturing process. A failure by the
Company to comply with present and future regulations could subject it to future
liabilities or the suspension of production. Such regulations could also
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. The Company may also from time to time be
subject to lawsuits with respect to environmental matters. The extent of the
Company's liability under any such suit is indeterminable and may, in certain
circumstances, have a material adverse effect on the Company.
 
     POSSIBLE VOLATILITY OF MARKET PRICE OF COMMON STOCK.  The trading price of
the common stock is subject to significant fluctuations in response to
variations in quarterly operating results, general conditions in the electronics
industry and other factors. In addition, the stock market is subject to price
and volume fluctuations which affect the market price for many high technology
companies in particular, and which can be unrelated to operating performance.
 
     ACQUISITIONS.  The Company may from time to time pursue the acquisition of
other companies, assets or product lines that complement or expand its existing
business. Acquisitions involve a number of risks that could adversely affect the
Company's operating results, including the diversion of management's attention,
the assimilation of the operations and personnel of the acquired companies, the
amortization of acquired intangible assets and the potential loss of key
employees. No assurance can be given that any acquisition by the Company will
not materially and adversely affect the Company or that any such acquisition
will enhance the Company's business.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholders and Board of Directors of
  HADCO CORPORATION:
 
     We have audited the accompanying consolidated balance sheets of Hadco
Corporation (a Massachusetts corporation) and subsidiaries as of October 26,
1996 and October 28, 1995, and the related consolidated statements of income,
stockholders' investment and cash flows for each of the three years in the
period ended October 26, 1996. 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 26, 1996 and October 28, 1995, and the results of
their operations and their cash flows for each of the three years in the period
ended October 26, 1996, 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 state, in all
material respects, the financial data required to be set forth therein, in
relation to the basic financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                OCTOBER 26, 1996
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Hadco Corporation (the "Company") is engaged primarily in the manufacture
and sale of printed circuits, backplanes and related products. The consolidated
financial statements reflect the application of certain accounting policies as
described in this note and elsewhere in the accompanying notes to the
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
 
     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.
 
  Cash Equivalents and Short-term Investments
 
     The Company considers all highly liquid investment instruments purchased
with a maturity of three months or less to be cash equivalents. Short-term
investments are carried at cost, which approximates market, and have maturities
of less than one year. Cash equivalents consist of $29,696,000 and $19,200,000
for the years ended October 1996 and 1995, respectively.
 
     The Company classifies its investments in corporate and government debt

     Statement of Financial Accounting Standards ("SFAS") No. 105, "Disclosure
of Information about Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentration of Credit Risk," requires disclosure of

electronics industry. The Company maintains the majority of its cash balances
with financial institutions. As of October 26, 1996, there were no significant
off-balance-sheet risks which would have a material or adverse effect on the
financial condition or net worth of the Company.

</TABLE>
 
  Net Income per Common and Common Equivalent Share
 
     Net income per common and common equivalent share was computed based on the
weighted average number of common and common equivalent shares outstanding
during each year. Common equivalent shares include outstanding stock options.
Fully diluted net income per share has not been separately presented as it would
not be materially different from net income per share as presented.
 
  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 1994, 1995 and 1996, research and
development expenses were approximately $1,545,000, $2,945,000 and $4,307,000,
respectively, and are included in operating expenses.
    
 
  New Accounting Standards
 
     The Company will adopt SFAS No. 123, "Accounting for Stock-Based
Compensation," in fiscal 1997. The standard defines a fair-valued-based method
of accounting for employee stock options and other stock-based compensation. The
compensation expenses arising from this method of accounting can be reflected in
the financial statements or, alternatively, the pro forma net income and
earnings per share effect of the fair-value-based accounting can be disclosed in
the financial footnotes. The Company will adopt the disclosure only alternative.
 
  Reclassifications
 
     The Company has reclassified certain prior year information to conform with
the current year's presentation.

     Due to the uncertainty relating to the actual value of the favorable tax
benefits of deferred compensation from stock options, the Company has recorded a
valuation allowance of approximately $137,000 and $290,000 as of October 26,
1996 and October 28, 1995. The reduction of this allowance for the year ending
October 26, 1996 is a result of the decrease in the deferred tax asset relating
to deferred compensation.
 
5.  LINES OF CREDIT
 
     The Company has an unsecured Revolving Credit and Term Loan Agreement with
a bank. The agreement provides for up to $15,000,000 in revolving credit until
June 30, 1997. The Company can designate

the rate of interest at either the Eurodollar Rate plus 0.6%, or the bank's Base
Rate. As of October 26, 1996, no amounts were outstanding under this line of
credit.
 
     The Company's line of credit places several restrictions on the Company,
including limitations on mergers, acquisitions and sales of a substantial
portion of its assets, as well as certain limitations on liens, guarantees,
additional borrowings and investments. This loan agreement also contains
provisions pertaining to the maintenance by the Company of certain levels of
consolidated tangible net worth, consolidated net income, debt to worth ratio
and consolidated net income to interest expense ratio during the term of the
loan. At October 26 1996, the Company was in compliance with all loan covenants.
 
     Additionally, the Company has a line of credit of $5,000,000 which is used
for equipment financing from a leasing company. Use of this line is subject to,
among other things, the approval by the leasing company of the equipment to be
leased. At October 26, 1996, the unused portion of this line was approximately
$4,759,000. This line expires during fiscal 1997.

respectively.
 
     These operating leases include office and manufacturing space leased from a
partnership in which the Chairman of the Board has an interest. Two of the
leases are for terms of five years, and expire in October 2000 with options to
extend until October 2006. The remaining lease expires in March 2000 with
options to extend until 2006. For the fiscal years ended October 1996, 1995 and
1994, the related rental expense was approximately $529,000, $479,000 and
$571,000, 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 recently executed a Modification of the Order on Consent
to implement the approved ROD. The cost, based upon the FFS, to implement this
remediation is estimated to be $4.6 million, and is expected to be expended as
follows: $260,000 for capital equipment and $4.3 million for operation and
maintenance costs which will be incurred and expended over the estimated life of
the program of 30 years. NYSDEC has requested that the Company consider taking
additional samples from a wetland area near the Company's Owego facility.
Analytical reports of earlier sediment samples indicated the presence of certain
inorganics. 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 second sentence of the fifth paragraph of this "Environmental Matters" note.
 
     From 1974 to 1980, the Company operated a printed circuit manufacturing
facility in Florida as a lessee of property that is now the subject of a pending
lawsuit ("the Florida Lawsuit") and investigation by the Florida Department of
Environmental Regulation (FDER). On June 9, 1992, the Company entered into a
Cooperating Parties Agreement in which it and Gould, Inc., another prior lessee
of the site, have agreed to fund certain assessment and feasibility study
activities at the site, and an environmental consultant has been retained to
perform such activities. The cost of such activities is not expected to be
material to the Company. In addition to the Cooperating Parties Agreement, Hadco
and others are participating in alternative dispute resolution regarding the
site with an independent mediator. In connection with the mediation, in February
1992 the FDER presented computer-generated estimates of remedial costs, for
activities expected to be spread over a number of years, that ranged from
approximately $3.3 million to $9.7 million. Mediation sessions were conducted in
March 1992 but have been suspended during the ongoing assessment and feasibility
activities. Management believes it is likely that it will participate in
implementing a continuing remedial program for the site, the costs of which are
currently unknown. However, based on information currently known by the Company,
management does not expect these costs to have a material adverse effect on the
Company. Also see the penultimate paragraph of this "Environmental Matters" note
relating to the Company's having been named as a third-party defendant in the
Florida Lawsuit.
 
     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. 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 fifth
paragraph of this "Environmental Matters" note.
 
   
     Included in operating expenses are charges for actual expenditures and
accruals, based on estimates, for environmental matters. During fiscal 1996 and
1995, the Company made, and charged to operating expenses, actual payments of
approximately $680,000 and $1,111,000, respectively, for environmental matters.
In 1996 and 1995, the Company also accrued and charged to operating expenses
approximately $1,825,000 and $2,740,000, respectively, as cost estimates for
environmental matters.
    
 
     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 $10.0
million and $8.2 million at October 26, 1996 and October 28, 1995, respectively.
The current portion of these costs as of October 26, 1996 and October 28, 1995,
amounted to approximately $900,000 in each year, and is included in "Other
accrued expenses." The long-term portion of these costs amounted to
approximately $9.1 million and $7.3 million as of October 26, 1996 and October
28, 1995, respectively, and is reported under the caption "Other Long-term
Liabilities." Based upon its assessment at the current time, management
estimates the cost of ultimate disposition of the above 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 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.
 
     The Company is one of thirty-three 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 April, 1996, the EPA published for comment, and
recommended for approval, a proposal to change the remedy at the Auburn Road
site from active groundwater remediation to future monitoring. Other parties to
the lawsuit also allege that future monitoring will be required. The Company is
contesting liability, but is participating in mediation with twenty-seven other
parties in an effort to resolve the lawsuit. Management believes that the
ultimate disposition of this lawsuit will not have a material adverse effect
upon the liquidity, capital resources, business or consolidated financial
position of the Company.
 
     In connection with the "Florida Lawsuit" (as described in the second
paragraph of this "Environmental Matters" note), pending in the Circuit Court of
Broward County, Florida, Hadco and Gould, Inc., another prior lessee of the site
of the printed circuit manufacturing facility in Florida, each was served with a
third-party complaint in June 1995, as third-party defendants in such pending
Florida Lawsuit by a party who had previously been named as a defendant when the
Florida Lawsuit was commenced in 1993 by the FDER. The Florida Lawsuit seeks
damages relating to environmental pollution and FDER costs and expenses, civil
penalties, and declaratory and injunctive relief to require the parties to
complete assessment and remediation of soil and groundwater contamination. The
other parties include alleged owners of the property.
 
     The future costs in connection with the lawsuits described in the two
immediately preceding 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.
 
  Purchase Commitments
 
     The Company has commitments to purchase approximately $10,690,000 of
manufacturing equipment. The majority of these commitments are expected to be
completed by the end of fiscal 1997.

---------------
 
* The Board of Directors has determined to make no further grants under the
  December 1985 Plan, December 1986 Plan, December 1987 Plan and September 1990
  Plan.
 
     The Company had reserved, as of October 26, 1996, a total of 2,124,594
shares of common stock for issuance under the nonqualified stock option plans
listed in the above chart. During fiscal 1996, 1995 and 1994, approximately
$154,000, $287,000, and $360,000, respectively, were charged against income as
compensation expense associated with the granting of these options.
 
     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.
 
9.  RETIREMENT PLAN
 
     The Hadco Corporation Retirement Plan (the "Plan"), as amended, covers all
employees with at least six months of continuous service (as defined). Annual
profit sharing contributions are determined at the discretion of the Board of
Directors but cannot exceed the amount allowable for federal income tax
purposes. The Company made profit sharing contributions of $3,335,000,
$2,285,000 and $1,074,000 to the Plan for the years ended October 1996, 1995 and
1994, respectively.
 
     The Plan permits participants to elect to have contributions made to the
Plan in the form of reductions in salary under Section 401(k) of the Internal
Revenue Code subject to limitations set out in the Plan. Under the Plan, the
Company will match employee contributions up to a set percentage. Employee
contributions become vested when made, and Company contributions become vested
at the rate of 33 1/3% for each year of service with the Company. The Company
matched employee contributions in the amount of approximately $736,000, $600,000
and $500,000 during fiscal 1996, 1995 and 1994, respectively.

     In December 1996, the Company entered into an agreement to acquire the
outstanding common stock of Zycon Corporation, a California based manufacturer
of printed circuit boards, for approximately $205 million or $18 per share. It
is expected that this transaction should be completed in January 1997 and will
be accounted for as a purchase business combination in accordance with APB No.
16 "Accounting for Business Combinations." In January 1997, the Company received
a $250 million revolving credit loan facility which will be used to finance this
acquisition. This new facility will terminate the $15,000,000 bank lending
facility described in footnote 5 above.
