              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (unaudited)


1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Hadco Corporation's (the "Company" or "Hadco") principal products are
      multilayer rigid printed circuits and backplane assemblies. The
      consolidated condensed financial statements reflect the application of
      certain accounting policies. For information as to the significant
      accounting policies followed by the Company and other financial and
      operating information, see this note and elsewhere in the accompanying
      notes to consolidated condensed financial statements, as well as the
      Company's Annual Report on Form 10-K for the fiscal year ended October 25,
      1997, Quarterly Report on Form 10-Q for the fiscal quarter ended January
      31, 1998, Current Reports on From 8-K dated February 18, 1998. February
      20, 1998, and May 1, 1998 and current report on From 8-K dated March 26,
      1998 as amended by Current Report on Form 8-K/A dated May 1, 1998. These
      financial statements should be read in conjunction with the financial
      statements included in those above-referenced SEC filings.

      FOREIGN CURRENCY TRANSLATION

      The functional currency of the Company's Malaysian subsidiary is the
      United States dollar. Accordingly, all remeasurement gains and losses
      resulting from transactions denominated in currencies other than United
      States dollars are included in the consolidated condensed statements of
      operations. To date, the resulting gains and losses have not been
      material.

      RECLASSIFICATION

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

      INTERIM FINANCIAL STATEMENTS

      The accompanying consolidated condensed balance sheet as of May 2, 1998,
      and the consolidated statements of operations and cash flows for the six
      month periods ended May 2, 1998 and April 26, 1997 are unaudited but, in
      the opinion of management, include all adjustments (consisting only of
      normal, recurring adjustments) necessary for a fair presentation of
      results for these interim periods. Results of operations for the interim
      period are not necessarily indicative of results to be expected for the
      entire year or any future period.

      NET INCOME (LOSS) PER SHARE

      The Company adopted SFAS No. 128, "Earnings per share", effective for the
      quarter ended January 31, 1998 which replaces the calculation of primary
      and fully diluted earnings per share with basic and diluted earnings per
      share. Prior period amounts have been restated to conform to the current
      period presentation. Under SFAS No. 128, basic net income (loss) per
      common share is computed based on income (loss) available to common
      stockholders and the weighted average number of common shares outstanding
      during the period. The dilutive net income (loss) per share is computed
      based on including the number of additional common shares that would have
      been outstanding if the dilutive potential of common shares had been
      issued.

</TABLE>

      Diluted weighted average shares outstanding for the three month periods
      ended May 2, 1998 and April 26, 1997, do not include 383,997 and 575,366
      common equivalent shares, respectively, as their effect would be
      anti-dilutive. Diluted weighted averages shares outstanding for the six
      month periods ended May 2, 1998 and April 26, 1997, respectively, do not
      include 401,798 and 571,815 common equivalent shares as their effect would
      be anti- dilutive.

2.    AQUISITIONS

      On January 10, 1997, the Company acquired (the "Zycon Acquisition") all of
      the outstanding common stock of Zycon Corporation ("Zycon"), and on March
      20, 1998, the Company acquired (the "Continental Acquisition", and
      together with the Zycon Acquistion, the "Acquisitions") all of the
      outstanding common stock of Continental Circuits Corp. ("Continental").
      These acquisitions were financed by the $400 million unsecured senior
      revolving credit facility with a group of banks, which amended and
      restated an existing credit facility (the "Amended Credit Facility"),
      under which the Company borrowed approximately $215,000,000 upon
      consummation of the Zycon Acquisition and approximately $220,000,000 upon
      consummation of the Continental Acquisition. These acquisitions were
      accounted for as purchases in accordance with Accounting Principles Board
      Opinion No. 16, and accordingly, Zycon's and Continental's operating
      results since the respective dates of acquisition are included in the
      accompanying consolidated condensed financial statements. In accordance
      with ABP Opinion No. 16, the Company allocated the purchase price of the
      Acquisitions based on the fair value of assets acquired and liabilities
      assumed. Significant portions of the purchase price of both Acquisitions
      were identified in independent appraisals as intangible assets using
      proven valuation procedures and techniques. 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 a future
      alternative use. Acquired intangibles include developed technology,
      customer relationships, assembled workforce, trade names and trademarks.
      These intangibles are being amortized over their estimated useful lives of
      12 to 30 years.

      Unaudited pro forma operating results for the Company, assuming the
      acquisitions of Zycon and Continental occurred on October 27, 1996, are as
      follows:

      For purposes of these pro forma operating results, the acquired in-process
      R&D was assumed to have been written off prior to October 27, 1996, so
      that the operating results presented include only recurring costs.

4.    INTANGIBLE ASSETS

      The Company has assessed the realizability of its acquired intangible
      assets in accordance with SFAS No.121, "Accounting for the Impairment of
      Long-Lived Assets and for Long-Lived Assets to be Disposed of. " Under
      SFAS No. 121, the Company is required to assess the valuation of its
      long-lived assets, including intangible assets, based on the estimated
      cash flows to be generated by such assets. See Note 7.

      The Company's $400 million Amended Credit Facility is pursuant to an
      Amended and Restated Revolving Credit Agreement, as amended (the
      "Agreement). The Agreement provides for direct borrowings or letters of
      credit for up to $400 million and expires January 8, 2002. Borrowings

      the Company, of the unused commitment under the Agreement. If the Company
      obtains certain debt financing, as defined, the banks may require the
      Company to repay up to $150,000,000 of amounts outstanding under the
      Agreement. At May 2, 1998, borrowings of $345,000,000 were outstanding
      under the agreement at a weighted average interest rate of 6.56%.

      The Agreement 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, changes in the Company's capitalization, as
      defined, and investments. The Agreement also requires the Company to
      maintain certain financial covenants, including, among other things,
      minimum levels of consolidated net worth, a maximum ratio of consolidated
      funded debt to EBITDA, maximum capital expenditures and minimum interest
      coverage, as defined, during the term of the Agreement. At May 2, 1998,
      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 $3.4 million for the purpose of acquiring land, facilities
      and equipment for the Company's Malaysian subsidiary. The arrangement is
      renewable annually. At May 2, 1998, there were no amounts outstanding
      under this arrangement.

7.    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. The component of this charge
      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 amount
      recorded as a liability, which totaled $1.5 million, relates to severance
      and other payroll-related costs, as well as lease termination costs.
      Non-recurring costs include costs associated with the abandonment of
      assets at one of the facilities. The components of the restructuring and
      other non-recurring costs during the three months ended May 2, 1998 are as
      follows:

</TABLE>

      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."

8.    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),

      ENVIRONMENTAL MATTERS (CONTINUED)

      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. 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 notified the Company that it
      will take 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
      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 Protection (FDEP). Hadco and others are
      participating in alternative dispute resolution regarding the site with an
      independent mediator. In connection with mediation, in February 1992 the
      FDEP 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 were then suspended during ongoing assessment
      and feasibility activities. On June 9, 1992, the Company entered into a
      Cooperating Parties Agreement in which it and Gould, Inc., another prior
      lessee of the site, agreed to fund certain assessment and feasibility
      study activities at the site. The cost of such activities is not expected
      to be material to the Company. 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. In June 1995, Hadco was
      named a third-party defendant in the Florida Lawsuit. See Note 9 below.

      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. 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 fifth paragraph of this Environmental Matters
      note.

      ENVIRONMENTAL MATTERS (CONTINUED)

      The City of Santa Clara adopted an ordinance that, as of April 1, 1997,
      reduced the amount of waste, including copper and nickel, that companies
      such as the Company may discharge into the city sanitary sewer. The
      ordinance provides for substantial penalties for intentional or negligent
      violations. These penalties include fines ranging from $10,000 to $50,000
      per day, revocation of required business permits, the issuance of a cease
      and desist order and, under certain circumstances, up to nine months'
      imprisonment. Under the ordinance, the Company is subject to stringent
      requirements on the amount of water it can discharge. The concentration
      limit for Hadco's copper discharge was reduced from 2.70 milligrams per
      liter to 1.02 milligrams per liter, and the concentration limit for
      Hadco's nickel discharge was reduced from 2.60 milligrams per liter to
      0.15 milligrams per liter. The Company believes it is currently in
      compliance with new discharge limits.

      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" note 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.

9.    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. Other parties to the lawsuit also allege that future
      monitoring will be required. The Company is contesting liability, but is
      participating in mediation with 27 other parties in an effort to resolve
      the lawsuit.

      In connection with the Florida Lawsuit pending in the Circuit Court for
      Broward County, Florida (described in Note 8 above), each of Hadco and
      Gould, Inc., another prior lessee of the site of the printed circuit
      manufacturing facility in Florida, 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 FDEP. The Florida Lawsuit seeks
      damages relating to environmental pollution and FDEP 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
      and Fleet Credit Corporation, a secured lender to a prior lessee of the
      property.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS


      LEGAL PROCEEDINGS AND CLAIMS (CONTINUED)

      In March 1993, the EPA notified Hadco Santa Clara (formerly Zycon) 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 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 site, rather the 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 agreement provides a
      mechanism for ensuring that an appropriate federal, state or local agency
      will assume regulatory responsibility for long-term maintenance.

      The future costs in connection with the lawsuits described in the
      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.

      On March 27, 1998, the Company received a written notice from legal
      counsel for the Lemelson Medical, Education & Research Foundation Limited
      Partnership (the "Lemelson Partnership"), alleging that the Company is
      infringing certain patents held by the Lemelson Partnership and offering
      to license such patents to the Company. The ultimate outcome of this
      matter is not currently determinable, and there can be no assurance that
      the outcome of this matter will not have a material adverse effect upon
      the Company's business, financial condition and results of operations.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS


      LEGAL PROCEEDINGS AND CLAIMS (CONTINUED)

      Litigation with respect to patents and other intellectual property matters
      can result in substantial damages, require the cessation of the
      manufacture, use and sale of infringing products and the use of certain
      processes, or require the infringing party to obtain a license to the
      relevant intellectual property.

      On January 12, 1998, Hadco Santa Clara (formerly Zycon) 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 a
      Zycon facility of effluent from allegedly toxic and hazardous chemical
      substances. Because this matter is at an early stage, the Company believes
      it cannot assess the potential range of damages that might be awarded
      should the plaintiffs prevail.

10.   SUBSEQUENT EVENT - DEBT OFFERING

      On May 18, 1998, the Company sold $200.0 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 so resold at a price equal to 99.66% of their principal
      amount.

      Interest on the Notes is payable semiannually on each June 15 and December
      15, commencing 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 $193,820 million, was used to repay
      outstanding indebtedness under the Amended Credit Facility previously
      incurred to, among other things, finance the Acquisitions.

      The Indenture under that 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.

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

      Except for the historical information contained herein, the matters
      discussed below or elsewhere in this quarterly report including, without
      limitation, "Environmental Matters," are forward-looking statements that
      involve risks and uncertainties. The Company makes such forward-looking
      statements under the provisions of the "Safe Harbor" section of the
      Private Securities Litigation Reform Act of 1995. Any forward-looking
      statements should be considered in light of the factors described below
      under "Factors That May Affect Future Results." Actual results may vary
      materially from those projected, anticipated or indicated in any
      forward-looking statements. In this quarterly report, the words
      "anticipates," "believes," "expects," "estimates," "intends," "may,"
      "future," "could," "will," and similar words or expressions (as well as
      other words or expressions referencing future events, conditions or
      circumstances) identify forward-looking statements.

      RESULTS OF OPERATIONS

      SECOND QUARTER

      Net sales for the second quarter of 1998 increased 16.0% over the same
      period in 1997. The increase resulted from several factors including the
      acquisition of Continental on March 20, 1998, which added $16.8 million to
      printed circuit net sales in the quarter, and an increase in backplane
      assembly net sales. Backplane assembly net sales increased 104.4 % due to
      higher product volume and shipments. Printed circuit net sales decreased
      0.5% due to lower production volume and shipments, and a 4.4% decrease in
      average pricing. The shift towards printed circuits with more layers and
      greater densities partially offset the decrease in the volume of shipments
      and decrease in price. Net sales from backplane assemblies increased to
      15.6% of net sales from 8.8% in the second quarter of 1997.

      The gross profit margin decreased to 17.5% in the second quarter of 1998
      from 21.3% in the comparable period in fiscal 1997. The decrease resulted
      from lower capacity utilization from printed circuit operations, and lower
      overall gross margins from the Hadco Santa Clara (formerly Zycon) and
      Hadco Phoenix (formerly Continental) operations.

      Operating expenses, as a percent of net sales, increased to 10.3% in the
      second quarter of 1998 from 10.0% in the comparable period in fiscal 1997
      due to increased goodwill and purchased intangibles amortization expenses
      from the acquisition of Continental.

      Income from operations for the second quarter of 1998 was reduced by
      approximately $63 million due to a non-recurring write-off relating to
      acquired in-process research and development recorded in connection with
      the Continental Acquisition, and by approximately $5.9 million in
      restructuring and other non-recurring charges related to the consolidation
      of the Company's East Coast Tech Center operations. The remaining goodwill
      and purchased intangibles from the Continental Acquisition will be
      amortized over 12 to 20 years, with an average amortization period of 16
      years, which will reduce income from operation by approximately $1.5
      million per fiscal quarter.

      Income from operations, as a percent of net sales, decreased prior to the
      write-off of acquired in-process research and development and the
      restructuring and other non-recurring charges to 7.3% in the second
      quarter of 1998 from 11.3% in the comparable period in fiscal 1997,
      primarily as a result of the decrease in gross profits.

      SECOND QUARTER (CONTINUED)

      Interest income decreased in the second quarter of 1998 as compared to the
      second quarter of 1997 due to lower average cash balances available for
      investing. Interest expense decreased slightly in the second quarter of
      1998 as compared to the second quarter of 1997, due to lower average
      outstanding debt balances for the second quarter of 1998 compared to the
      second quarter of 1997.

      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
      environmental matters. 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.

      The Company believes that excess capacity may exist in the printed circuit
      and electronic assembly industries. 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.
      However, the Company has historically needed to increase its manufacturing
      capacity to maintain and expand its market position, although the
      Company's manufacturing capacity needs could change at any time or times
      in the future. The Company also believes that the potential exists for a
      shortage of materials in the printed circuit and electronic assembly
      industries, which could have a material adverse effect 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 will be sufficient to protect the Company against any
      shortages of materials.

      YEAR TO DATE

      Net sales for the six months ended May 2, 1998 increased 39.6% over net
      sales for the six months ended April 26, 1997. The increase resulted from
      several factors including the acquisitions of Zycon and Continental, which
      added $80.2 million to printed circuit net sales in the six month period,
      and an increase in both backplane assembly and printed circuit net sales
      (excluding these Acquisitions). Backplane assembly net sales increased due
      to higher production volume and shipments. Printed circuit net sales
      increased due to higher production volume and shipments and a shift
      towards products with more layers and greater densities. In addition,
      average pricing for printed circuits decreased 3.4% for the first six
      months of fiscal 1998 over the same period in fiscal 1997. Net sales from
      backplane assemblies increased to 14.2% of net sales from 11.7% in the
      first six months of fiscal 1997.

      The gross profit margin decreased to 18.6% in the six months ended May 2,
      1998 from 22.2% in the comparable period in fiscal 1997. The decrease
      resulted from lower capacity utilization from printed circuit facilities,
      and lower overall gross margins from the Hadco Santa Clara and Hadco
      Phoenix operations.

      Operating expenses, as a percent of net sales, decreased to 9.6% in the
      six months ended May 2, 1998 from 9.9% in the comparable period in fiscal
      1997, due to increased net sales and the fixed nature of the Company's
      operating expenses. The decrease was partially offset by goodwill and
      purchased intangibles amortization.

<PAGE>   17

      YEAR TO DATE (CONTINUED)

      Income from operations for the six months ended May 2, 1998 and April 26,
      1997, was reduced by $63 million and $78 million, respectively, over the
      comparable respective preceding periods, due to non-recurring write-offs
      of acquired in-process research and development recorded in connection
      with the Continental and Zycon acquisitions. The remaining goodwill and
      purchased intangibles will be amortized over 12 to 30 years, with an
      average amortization period of 17 years, which will reduce income from
      operations by approximately $3.1 million per fiscal quarter. In addition,
      income from operations for the six months ended May 2, 1998, was reduced
      by approximately $5.9 million for restructuring and other non-recurring
      charges related to the consolidation of the Company's East Coast Tech
      Center operations.

      Excluding the non-recurring write-off and restructuring charges, income
      from operations as a percent of net sales, decreased to 8.9% for the six
      months ended May 2, 1998 from 12.3% in the comparable period in fiscal
      1997, primarily as a result of the same factors affecting gross profit
      margins, and of goodwill and purchased intangibles amortization from the
      acquisitions.

      Interest income increased in the six months ended May 2, 1998 as compared
      to the six months ended April 26, 1997, due to higher daily average cash
      balances available for investing. Interest expense increased in the six
      months ended May 2, 1998 as compared to the six months ended April 26,
      1997, due to an increase in outstanding debt as a result of the
      acquisitions.

      INCOME TAXES

      In accordance with generally accepted accounting principles, the Company
      provides for income taxes on an interim basis, using its effective annual
      income tax rate. Although the Company has recorded a loss before income
      taxes in 1998 and 1997, the Company anticipates an effective annual income
      tax rate for fiscal 1998 of 39.75%, which is slightly less than 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. The effective tax rate for fiscal
      1998 is based on current tax laws.

      LIQUIDITY AND CAPITAL RESOURCES

      At May 2, 1998, the Company had working capital of approximately $98.6
      million and a current ratio of 1.80, compared to working capital of
      approximately $53.7 million and a current ratio of 1.48 at October 25,
      1997. Cash, cash equivalents and short-term investments at May 2, 1998
      were approximately $5.0 million, a decrease of $8.7 million from
      approximately $13.7 million at October 25, 1997.

      In December 1997, the Company negotiated a $400 million unsecured senior
      revolving credit loan facility with a group of banks, which amended and
      restated an existing credit facility (the "Amended Credit Facility").
      Interest on loans outstanding under the Amended Credit Facility is, at the
      Company's option, payable at either (1) the Eurodollar Rate plus the
      Applicable Eurodollar Rate Margin (both as defined in the Amended Credit
      Facility), or (2) the Base Rate as defined in the Amended Credit Facility.
      At May 2, 1998, $345 million was outstanding under the Amended Credit
      Facility. The Amended Credit Facility matures in January 2002. See Notes 5
      and 10 of Notes to Consolidated Condensed Financial Statements above.


                                       17
<PAGE>   18


      LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

      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 through fiscal 1998. 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.

      DEBT OFFERING

      On May 18, 1998, the Company sold $200.0 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 so resold at a price equal to 99.66% of their principal
      amount. 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 $193,820 million,
      was used to repay outstanding indebtedness under the Amended Credit
      Facility previously incurred to, among other things, finance the
      Acquisitions. The Indenture under that 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. See Note 10 of Notes to Consolidated
      Condensed Financial Statements above.

      YEAR 2000 COMPLIANCE

      The Company is reviewing the areas within its business and operations
      which could be adversely affected by Year 2000 issues and evaluating the
      costs associated with modifying and testing its systems for the Year 2000.
      Although the company is not yet able to estimate its incremental cost for
      Year 2000 issues, based on its preliminary review to date, the Company
      does not believe Year 2000 issues will have a material adverse effect on
      the Company's business, financial condition or results of operations. The
      Company is also working with suppliers to ensure their systems are Year
      2000 compliant as well. All costs associated with supplier compliance will
      be borne by the suppliers.

      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.

      DEPENDENCE ON ELECTRONICS INDUSTRY

      The Company's principal customers are electronics Original Equipment
      Manufacturers (OEMs) and contract manufacturers 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 

                                       18

<PAGE>   19

      DEPENDENCE ON ELECTRONICS INDUSTRY (CONTINUED)

      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 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.

      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 from and
      shipments to customers 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, 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 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 timing and volume of orders placed
      by the Company's customers vary due to customer attempts to manage
      inventory, changes in customers' manufacturing strategies and variation in
      demand for customer products. 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.

      VARIABILITY OF ORDERS

      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 variation 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 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 orders by a customer or
      group of customers could materially adversely affect the Company's
      business, financial condition and results of operations.


                                       19

      ACQUISITIONS

      On March 20, 1998, the Company acquired (the "Continental Acquisition")
      all of the outstanding capital stock of Continental Circuits Corp.
      ("Continental"), for approximately $188 million (including acquisition
      costs). On January 10, 1997, the Company acquired (the "Zycon
      Acquisition", and together with the Continental Acquisition, the
      "Acquisitions") all of the outstanding capital stock of Zycon Corporation
      ("Zycon"), for approximately $212 million (including acquisition costs).
      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 the acquired businesses profitably in the
      future. The gross profit margins for Continental and Zycon for their
      respective fiscal years ended July 31, 1997 and December 31, 1996 were
      18.2% and 15.7%, respectively. The gross profit margins for Hadco (not
      including Continental or Zycon) for its fiscal years ended October 26,
      1996 and October 25, 1997 were 25.8% and 21.8%, respectively. As a result
      of the Acquisitions, the Company expects its gross profit margin will be
      lower in future fiscal quarters than has historically been the case.
      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. In addition, shortly after the
      Continental Acquisition, one senior member of Continental's management
      left the Company. There can be no assurance that the Company will be able
      to retain key personnel at Continental.

      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, and such incurrences could have a
      material adverse effect on the Company's business, financial condition and
      results of operations. See "Leverage" below. The 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.

      MANAGEMENT OF GROWTH

      In fiscal 1997 and 1998, the Company has significantly expanded its
      operations, including geographically, which has 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 personnel. The Company's ability to manage growth effectively,
      particularly given the increasing scope of its operations, will require it
      to continue to implement and improve its operational, financial and
      management information systems as well as to further develop the
      management skills of its managers and supervisors and to train, motivate
      and manage its employees. The Company's failure to effectively manage
      future growth could have a materiel adverse effect on the Company's
      business, financial condition and results of operations. Competition for
      personnel is intense, and there can be no assurance that the Company will
      be able to attract, assimilate or retain additional highly qualified
      employees in the future, especially engineering personnel. The failure to
      hire and retain such personnel could have a material adverse effect on the
      Company's business, financial condition and results of operations.


                                       20
<PAGE>   21

      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 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.

      During periods of recession or economic slowdown in the electronics
      industry and other periods when excess capacity exists, electronics OEMs
      become more price sensitive, which could have a material adverse effect on
      interconnect pricing. 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 are currently experiencing. 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.

      MALAYSIA FACILITY AND ASIAN ECONOMIC TURMOIL

      Hadco Santa Clara (formerly Zycon) completed construction of a volume
      manufacturing facility for printed circuits in Malaysia in fiscal 1997.
      Hadco's management has no experience in operating foreign manufacturing
      facilities, and there can be no assurance that the Company will operate
      the new facility on a profitable basis. The Company believes that the
      Malaysian facility could incur operating losses in the future as a result
      of various factors, including, without limitation, operating
      inefficiencies and price competition for the products which the Company
      intends to produce at the facility. 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. Malaysia and other Asian countries
      have recently 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 or results of
      operations.

      TECHNOLOGICAL CHANGE, PROCESS DEVELOPMENT AND 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 such as an earthquake, fire, flood or
      drought 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.

      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 1995, 1996 and 1997, the Company's ten
      largest customers accounted for approximately 46%, 48% and 47% of net
      sales, respectively. In fiscal 1997, Solectron accounted for approximately
      15% of the net sales of the Company. 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 could have a material adverse effect on
      the Company's business, financial condition and results of operations.

      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 


                                       22

<PAGE>   23

      MANUFACTURING CAPACITY (CONTINUED)

      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 and electronic assembly
      industries. 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.

      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, 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 not have a material adverse effect
      on the Company's business, financial condition and results of operations.

      AVAILABILITY OF RAW MATERIALS AND COMPONENTS

      Although the Company has not entered into any supply agreements and does
      not have any guaranteed sources of raw materials or components, it
      routinely purchases raw materials and components from several key material
      suppliers. Although alternative material suppliers are currently
      available, a significant unplanned event at a major supplier could have a
      material adverse effect on the Company's operations. Hadco Santa Clara has
      experienced shortages of certain types of raw materials in the past. The
      Company believes that the potential exists for shortages of materials 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, standard laminate materials, multilayer blanks, electronic
      components and other materials, and therefore such materials may not be
      readily available to the Company in the future. Electronic components used
      by the Company in producing backplane 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


                                       23
<PAGE>   24

      AVAILABILITY OF RAW MATERIALS AND COMPONENTS (CONTINUED)

      not occur in the future. Component shortages or price fluctuations could
      have a material adverse effect on the Company's backplane assembly
      business, thereby materially adversely affecting the Company's business,
      financial condition and results of operations. To the extent that the
      Company's backplane assembly business expands as a percentage of the
      Company's net sales, component shortages and price fluctuations could, to
      a greater extent, materially adversely affect the Company's business,
      financial condition and results of operations.

      DEPENDENCE ON KEY PERSONNEL

      The Company's future success depends to a large extent upon the continued
      services of key managerial and technical employees. The only executive
      officers of the Company bound by employment or non-compete agreements are
      the President and Chief Executive Officer and a Senior Vice President
      (formerly President and Chief Executive Officer of Continental). Hadco's
      President and Chief Executive Officer's non-compete agreement expires one
      year after the termination of his employment with the Company. Most other
      key employees of the Company do not 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.

      INTELLECTUAL PROPERTY

      The Company's success depends in part on its proprietary techniques and
      manufacturing expertise, particularly in the area of complex multilayer
      printed circuits. 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.

      VOLATILITY OF STOCK PRICE

      The Company's Common Stock has experienced significant price volatility
      historically, and such volatility may continue to occur in the future.
      Factors such as announcements of large customer orders, order
      cancellations, new product introductions by the Company or competitors or
      general conditions in the electronics industry, as well as quarterly
      variations in the Company's actual or anticipated results of operations,
      may cause the market price of the Company's Common Stock to fluctuate
      significantly. Furthermore, the stock market has experienced extreme price
      and volume fluctuations in recent years, which has had a substantial
      effect on the market price for securities issued by many technology
      companies, often for reasons unrelated to the operating performance of the
      specific companies. These broad market fluctuations may materially
      adversely affect the price of the Company's Common Stock. There can be no

<PAGE>   25

      VOLATILITY OF STOCK PRICE (CONTINUED)

      assurance that the market price of the Company's Common Stock will not
      experience significant fluctuations in the future, including fluctuations
      that are unrelated to the Company's performance.

      LEVERAGE

      The Acquisitions and related debt financings have significantly increased
      the Company's debt service obligations. Although the Company's cash flow
      from operations has been sufficient to meet its debt service obligations
      in the past, there can be no assurance that the Company's operating
      results will continue to be sufficient for the Company to meet such
      obligations in the future.

      FORWARD-LOOKING STATEMENTS

      A number of the matters and subject areas discussed in this Form 10-Q that
      are not historical or current facts deal with potential future
      circumstances and developments. The discussion of such matters and subject
      areas is qualified by the inherent risks and uncertainties surrounding
      future expectations generally, and also may differ materially from the
      Company's actual future experience involving any one or more of such
      matters and subject areas. The Company has attempted to identify, in
      context, certain of the factors that it currently believes may cause
      actual future experience and results to differ from the Company's current
      expectations regarding the relevant matter or subject area. The operations
      and results of the Company's business also may be subject to the effect of
      other risks and uncertainties in addition to the relevant qualifying
      factors identified elsewhere in the foregoing "Factors That May Affect
      Future Results" section, including, but not limited to other risks and
      uncertainties described from time to time in the Company's reports filed
      with the Securities and Exchange Commission.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings

      See Note 9 of Notes to Consolidated Condensed Financial Statements above
for a description of certain litigation in which the Company is currently
involved.

Item 2. Changes in Securities

      (a) An amendment to the Company's Restated Articles of Organization to
increase the number of authorized shares of Common Stock from 25,000,000 shares
to 50,000,000 shares was approved at the Annual Meeting of Stockholders on March
4, 1998. Articles of Amendment were filed with the Commonwealth of Massachusetts
on March 4, 1998.

      (b) On May 18, 1998, the Company sold $200.0 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 so resold at a
price equal to 99.66% of their principal amount. The Indenture under the which
the Notes were issued 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.

      (c)(i) Under the Company's Outside Directors' Compensation Plan of 1998
            (the "Outside Directors' Plan"), non-employee directors
            ("Non-Employee Directors") of the Company receive payment of an
            annual fee in the form of restricted Common Stock of the Company.
            Non-Employee Directors may elect to defer receipt of any such
            payment. On March 4, 1998, the Non-Employee Directors received an
            aggregate of 1,290 shares of Common Stock pursuant to the Outside
            Directors' Plan. Of such shares, receipt of 215 shares was deferred
            in accordance with the Outside Directors' Plan. The aggregate value
            of all such shares issued on March 4, 1998 to Non-Employee Directors
            was $59,985 (based on a fair market value on that date of $46.50 per
            share).

      (ii)  On March 20, 1998, and as a condition to his employment as a Senior
            Vice President of the Company, Frederick G. McNamee, III, agreed to
            purchase 40,000 shares of Common Stock of the Company pursuant to a
            Stock Purchase Agreement dated as of March 20, 1998. The purchase
            price of $37.00 per share was based on the fair market value of such
            shares on March 20, 1998, the date of purchase.

      (iii) Each of the shares of Common Stock of the Company referenced in this
            Item 2, Subsection (c) was issued by the Company in reliance on the
            exemption from registration provided by Section 4(2) of the
            Securities Act for an offering to a small number of knowledgeable
            investors.

Item 4. Submission of Matters to a Vote of Security Holders

      (a)   The annual meeting of stockholders of Hadco Corporation was held on
            March 4, 1998.

      (b)   No information provided due to inapplicability of item.

      (c)   A vote was proposed to (1) fix the number of directors at eight (8)
            and to elect a Board of Directors to serve for the ensuing year or
            until their respective successors are duly elected and qualified;
            (2) approve Hadco Corporation Employee Stock Purchase Plan of
            November 17, 1997; (3) approve the amendment of the Corporation's
            Restated Articles of Organization to increase the authorized shares
            of Common Stock from 25,000,000 to 50,000,000; (4) ratify the
            selection of Arthur Andersen LLP as auditors for the fiscal year
            ending October 31, 1998.

                                HADCO CORPORATION

                         NON-QUALIFIED STOCK OPTION PLAN

                                NOVEMBER 29, 1995

                      AS AMENDED AND RESTATED APRIL 7, 1998

             1. Purpose. This Non-Qualified Stock Option Plan (hereinafter, the
"Plan") is intended to promote the interests of Hadco Corporation (hereinafter,
the "Company") by providing an inducement for highly qualified personnel to
enter the employ of the Company and an incentive for valued employees to remain
with the Company and to use their best efforts to promote the Company's
continued success, by means of the offer of an opportunity to acquire or
increase their proprietary interest in the Company through the granting of
options to purchase the Company's stock pursuant to the terms of this Plan. As
used herein, the term "Company" includes any present or future subsidiary and
any successor corporation.

             2. Rights to be Granted. Under this Plan, options may be granted
that give an optionee the right for a specified time period to purchase a
specified number of shares of common stock, par value $0.05, of the Company. The
option price shall be determined in each instance by the Stock Option Committee,
in accordance with the terms of this Plan, including, without limitation, under
Section 7 hereof.

             3. Available Shares. The total number of shares of common stock,
par value $0.05, of the Company, for which




                                     - 1 -
<PAGE>   2
options may be granted shall be One Million (1,000,000) shares, subject to
adjustment in accordance with Paragraph 11 of this Plan. Shares subject to the
Plan may be either authorized but unissued shares or shares that were once
issued and subsequently reacquired by the Company. If any options granted under
this Plan are surrendered before exercise or lapse without exercise, in whole or
in part, the shares reserved therefor shall revert to the option pool and shall
continue to be available under the Plan. No one employee of the Company may be
granted options to acquire, in the aggregate, more than 300,000 shares of Common
Stock under this Plan. If any option granted under this Plan shall expire or
terminate for any reason without having been exercised in full or shall cease
for any reason to be exercisable in whole or in part or shall be repurchased by
the Company, the shares subject to such option shall be included in the
determination of the aggregate number of shares of common stock deemed to have
been granted to such employee under this Plan.

             4. Administration. The Plan shall be administered by the Stock
Option Committee (hereinafter, the "Committee"), which shall consist of two or
more members appointed by the Board of Directors of the Company; provided,
however that the Plan shall be administered: (I) to the extent required by
applicable regulations under Section 162(m) of the Internal Revenue Code of
1986, by two or more "outside directors" (as defined in applicable regulations
thereunder) and (ii) to the extent required by Rule 16b-3 promulgated under the
Securities Exchange Act of 1934 or any successor provision ("Rule 16b-3"), by a


                                     - 2 -
<PAGE>   3
disinterested administrator or administrators within the meaning of Rule 16b-3.
The Board may at any time and from time to time thereafter appoint additional or
substitute members of the Committee and may fill vacancies on the Committee,
however caused. No person shall be a member of the Committee who is not a
Director of the Company.

             In the event no Committee is appointed, the Board shall act as the
Committee and all references in this Plan to the Committee shall mean the Board.
If a Committee is appointed but under applicable law does not have authority to
undertake any duty stated herein, the Board shall act as and for the Committee
for the purpose of undertaking that particular duty.

             The Committee shall choose one of its members as Chair and shall
hold meetings at such times and places as it deems advisable. A majority of the
members of the Committee shall constitute a quorum, and any action may be taken
by a majority of those present and voting at any meeting.

             Subject to the provisions of this Plan, the Committee shall have
authority in its discretion to determine the employees of the Company to whom
options shall be granted, the number of shares to be covered by each option, the
time or times at which options shall be granted, the purchase price of the stock
covered by each option, the time or times during the term of option (defined in
Section 9) at which each such option shall become exercisable, the form of
agreement to be used in granting the options, and shall further have the
authority to interpret this Plan, and to prescribe, amend and rescind rules and




                                     - 3 -
<PAGE>   4
regulations relating to it. All questions of interpretation and application of
this Plan and of any options issued under it shall be determined by the
Committee, and such determination shall be final and binding upon all persons.

             No member of the Board or of the Committee shall be liable for any
action or determination made in good faith with respect to the Plan or any
option granted under it.

             5. Grant of Options. The Committee may from time to time grant
options to eligible persons pursuant to the provisions of this Plan. Each
option so granted shall be evidenced by an Option Agreement, in such form as may
be approved by the Committee, which Agreement shall be duly executed and
delivered on behalf of the Company and by the optionee to whom such option is
granted. The Agreement may contain such terms, provisions, and conditions not
inconsistent with the Plan as may be determined by the Committee, including
restrictions to be imposed on the shares acquired by a participant upon the
exercise of an option granted to him.

             The grant of an option under this Plan shall be effective as of the
date of the vote of the Stock Option Committee of the Board of Directors of
the Company to issue such an option. The granting of options under this Plan
shall be entirely discretionary and nothing in this Plan shall be deemed to give
any employee any right to participate in this Plan or to receive options.

             The grant of an option under this Plan confers no right upon the
optionee with respect to the continuation of his



                                     - 4 -
<PAGE>   5
employment with the Company or a subsidiary of the Company. Nothing contained in
this Plan or any option agreement issued hereunder shall be construed as
interfering with or restricting the right of the Company or its subsidiary or
the optionee to terminate his employment at any time.

             6. Eligibility and Limitations. Options may be granted pursuant to
this Plan only to employees of the Company or of any present or future
subsidiary corporation; provided, however, that a person shall be considered to
be an employee within the meaning of this Plan if the person has executed a
written employment agreement with the Company which provides for the start of
active employment within one (1) month of the date of grant of an option. In
determining the eligibility of an individual to be granted an option, as well as
in determining- the number of shares to be optioned to any individual, the
Committee shall consider the responsibilities of the person being considered,
the nature and value to the Company or its subsidiaries of his service and
accomplishments, his present and potential contribution to the success of the
Company or its subsidiaries, and such other factors as the Committee may deem
relevant.

             No option may be granted under this Plan after December 31, 2005.

             7. Option Price. The purchase price of the stock covered by an
option granted pursuant to this Plan shall be the fair market value of the
underlying shares of Common Stock on the date the option is granted.

             If the Company's common stock is actively traded in



                                     - 5 -
<PAGE>   6
the established over-the-counter market, the fair market value of such common
stock shall be the mean between the bid and asked prices quoted in such
over-the-counter market at the close on the date nearest preceding the date of
grant. If such common stock is listed on any national exchange, or traded in the
Nasdaq National Market, the mean between the high and low sale prices quoted on
such exchange or market on the trading day nearest preceding the date of the
granting of the option may be taken as such fair market value. If the stock is
not publicly traded, the fair market value shall be determined from time to time
by the Board of Directors.

             The full purchase price per share (determined after any appropriate
adjustment has been made under the terms of Section 11 of this Plan) shall be
paid as provided in Section 8 below.

             8. Exercise of Option. Subject to the terms and conditions of this
Plan and the Option Agreement, an option granted hereunder shall be exercisable
in whole or in part by giving written notice to the Company by mail or in person
addressed to Treasurer, Hadco Corporation, 12A Manor Parkway, Salem, New
Hampshire 03079, stating the number of shares with respect to which the option
is being exercised, accompanied by payment in full for such shares, which
payment may be made (a) in United States dollars in cash or by check, or (b) at
the discretion of the Committee, through delivery of shares of Common Stock
having a fair market value equal as of the date of the exercise to the cash
exercise price of the option, or (c) at the



                                     - 6 -
<PAGE>   7
discretion of the Committee and consistent with applicable law, through the
delivery of an assignment to the Company of a sufficient amount of the proceeds
from the sale of the Common Stock acquired upon exercise of the option and an
authorization to the broker or selling agent to pay that amount to the Company,
which sale shall be at the participant's direction at the time of exercise, or
(d) at the discretion of the Committee, by any combination of (a), (b) and (c)
above. There shall be no such exercise at any one time as to fewer than one
hundred (100) shares or all of the shares then purchasable by the person or
persons exercising the option, if fewer than one hundred (100) shares. A copy of
such notice shall be provided to Berlin, Hamilton & Dahmen, 73 Tremont Street,
Boston, Massachusetts 02108, or to such other counsel as the Company may
hereafter designate, and to the Bank of Boston, Shareholder Services Division,
Post Office Box 644, Boston, Massachusetts 02102, or to such other Stock
Transfer Agent as the Company may hereafter designate. The Transfer Agent shall,
on behalf of the Company, prepare a certificate or certificates representing
such shares acquired pursuant to exercise of the option, shall register the
optionee as the owner of such shares on the books of the Company and shall cause
the fully executed certificate(s) representing such shares to be delivered to
the optionee as soon as practicable after payment of the option price in full.
The holder of an option shall not have any rights of a shareholder with respect
to the shares covered by the option, except to the extent that one or more
certificates for such shares shall be


                                     - 7 -
<PAGE>   8
delivered to him upon the due exercise of the option.

             9. Term and Transferability of Options.

             (a) Each option shall become exercisable as provided in each option
granted by the Company to the participant and as provided in each respective
Option Agreement, but in no event shall the option be exercisable during a
period longer than the period beginning with the date of grant and ending not
later than ten (10) years from such date of grant.

             (b) Any option granted pursuant to this Plan shall not be
assignable or transferable except by will or by the laws of descent and
distribution. During the lifetime of the optionee, any option shall be
exercisable only by the optionee to whom the option is granted. Any option
granted hereunder shall be null and void and without effect upon the bankruptcy
of the optionee to whom the option is granted, or upon any attempted assignment
or transfer, including without limitation, any purported assignment, whether
voluntary or by operation of law, pledge, hypothecation or other disposition,
attachment, trustee process or similar process, whether legal or equitable, upon
such option.

             10. Termination of Option Rights.

             (a) In the event an optionee ceases to be an employee of the
Company for any reason other than death, retirement with the consent of the
Company or disability, any unvested or unexercised options granted to such
optionee shall terminate and become void at midnight on the thirtieth day after
the date of termination, but in no event later than the specified expiration
date of the option.




                                     - 8 -
<PAGE>   9
             (b) In the event that an optionee ceases to be an employee of the
Company by reason of his or her disability or death, any option granted to such
optionee shall be immediately and automatically accelerated and all previously
unexercised options (to the extent that they have not previously been forfeited
in accordance with the terms of the individual option agreement) shall vest and
be exercisable (by the optionee's personal representative, heir or legatee, in
the event of death) during the period ending one hundred eighty (180) days after
the date of termination of employment, but in no event later than the specified
expiration date of the option.

             (c) In the event an optionee ceases to be an employee of the
Company by reason of his or her retirement with the consent of the Company, any
option granted to such employee which had vested as of the date of retirement
may be exercised during the period ending ninety (90) days after the date or
retirement, but in no event later than the specified expiration date of the
option.

             (d) For purposes of the Plan, a transfer of an employee between the
parent Company and a subsidiary company, or between subsidiary companies, shall
not be deemed a termination of employment.

             11. Adjustments Upon Changes in Capitalization.

             (a) In the event that the outstanding shares of the Common Stock of
the Company are changed into or exchanged for a different number or kind of
shares or other securities of the Company by reason of any reorganization,
recapitalization,



                                     - 9 -
<PAGE>   10
reclassification, stock split-up, combination of shares or dividends payable in 
capital stock, appropriate adjustments shall be made in the number and kind of 
shares as to which options may be granted under the Plan and as to which 
outstanding options or portions thereof then unexercised shall be exercisable, 
to the end that the proportionate interest of the option holder shall be 
maintained as before the occurrence of such event. Such adjustment in
outstanding options shall be made without change in the total price applicable
to the unexercised portion of such options and with a corresponding adjustment
in the option price per share.

             (b) Upon any sale of all or substantially all of the assets of the
Company, or upon any merger, consolidation or tender offer in respect of which
the stockholders holding all of the Company's outstanding voting securities
immediately prior to the consummation thereof hold less then 50% of all of the
Company's outstanding voting securities immediately after such consummation
(each of the foregoing sale, merger, consolidation or tender offer hereinafter
called an "Acquisition"), then the date upon which all then outstanding options
granted under this Plan become fully vested and exercisable shall be
automatically accelerated to occur immediately prior to the consummation of such
Acquisition; provided, however, that any such then outstanding options which are
not thereupon exercised in full immediately prior to the consummation of such
Acquisition shall thereupon terminate.

             (c) In the event of a recapitalization or reorganization



                                     - 10 -
<PAGE>   11
of the Company (other than a transaction described in subsections 11(a) and (b)
above) pursuant to which securities of the Company or of another corporation are
issued with respect to the outstanding shares of Common Stock, an optionee upon
exercising an option shall be entitled to receive for the purchase price paid
upon such exercise securities he or she would have received if he or she had
exercised such option prior to such recapitalization or reorganization. In the
event of the proposed dissolution or liquidation of the Company, each option
will terminate immediately prior to the consummation of such proposed action or
at such other time and subject to such other conditions as shall be determined
by the Committee. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares subject to options. No
adjustments shall be made for dividends paid in cash or in property other than
securities of the Company. No fractional shares shall be issued under the Plan
and the optionee shall receive from the Company cash in lieu of such fractional
shares. Upon the happening of any of the events described in this Section 11,
the class and aggregate numbers of shares set forth in Section 3 hereof that are
subject to options which previously have been or subsequently may be granted
under this Plan, as well as the 300,000 figure in Section 3, shall also be
appropriately adjusted to reflect the events described in such subparagraphs.
The Committee or the Successor Board shall


                                     - 11 -
<PAGE>   12
determine the specific adjustments to be made under this Section 11 and, subject
to Section 2, its determination shall be conclusive.

             12. Restrictions on Issuance of Shares.

Notwithstanding the provisions of Section 8 of the Plan, the Company shall have
no obligation to deliver any certificate or certificates upon exercise of an
option until one of the following conditions shall be satisfied:

                       (i) The shares with respect to which the option has been
             exercised are at the time of the issue of such shares effectively
             registered under applicable Federal and State securities acts as
             now in force or hereafter amended; or

                       (ii) Counsel for the Company shall have given an opinion
             that such shares are exempt from registration under Federal and
             State securities acts as now in force or hereafter amended; and 
             until the Company has complied with all applicable laws and 
             regulations, including without limitation all regulations required 
             by any stock exchange upon which the Company's outstanding common 
             stock is then listed.

             The Company shall use its best efforts to bring about compliance
with the above conditions within a reasonable time, except that the Company
shall be under no obligation to cause a registration statement or a
post-effective amendment to any registration statement to be prepared at its
expense solely for the purpose of covering the issue of shares in respect of


                                     - 12 -
<PAGE>   13
which any option may be exercised.

             Any stock purchased under the Plan prior to shareholder approval of
the Plan may not be sold, assigned, transferred, pledged or encumbered in any
way and will be held in escrow by the Company until shareholder approval for the
Plan is obtained, and if such approval is not obtained by the earlier of (i) the
next annual meeting of stockholders of the Company, or (ii) June 30, 1996, the
purchase of such stock and any option granted hereunder and this Plan will be
automatically rescinded and the purchase price returned to purchasing optionees
without interest.

             13. Representations of Optionee. The Company may require the
optionee to deliver such written warranties and representations upon exercise of
the option that the Company deems reasonable or necessary, including without
limitation a representation that a purchase of shares under the option is made
for investment and not with a view to their distribution (as that term is used
in the Securities Act of 1933).

             14. Modification of Outstanding Options. The Committee or the
Board of Directors may accelerate the exercisability of any outstanding option
and may authorize changes to any outstanding option with the consent of the
participant (including, without limitation, to extend the term of an option upon
termination of employment to a date not later than ten (10) years from the
original grant date) when and subject to such conditions as are deemed to be in
the best interests of the Company and in accordance with the purposes of the
Plan.



                                     - 13 -
<PAGE>   14
             15. Approval of Stockholders. The Plan shall be subject to approval
by the affirmative vote of stockholders holding at least a majority of the
voting stock of the Company voting in person or by proxy at or by the earlier of
(i) the next annual meeting of stockholders of the Company, or (ii) June 30,
1996, and the Plan shall take effect as of the date of adoption immediately upon
such approval.

             16. Termination and Amendment of Plan. The Plan shall expire at the
end of the business day on December 31, 2005 (except as to options outstanding
on that date). The Board may at any time terminate the Plan or make such
modification or amendment thereof as it deems advisable; provided, however, that
except as provided in Section 11 the Board may not, without approval of the
stockholders of the Company obtained in the manner stated in Section 15 (without
regard to clauses (i) and (ii) therein), increase the maximum number of shares
for which options may be granted under the Plan. To the extent required by Rule
16b-3, any other amendments to this Plan shall be approved by the stockholders
of the Company in the manner stated in Section 15 (without regard to clauses (i)
and (ii) therein). Termination or any modification or amendment of the Plan
shall not, without consent of a participant, affect his rights under an option
previously granted to him.

             17. Withholding of Additional Income Taxes. Upon any exercise of
any option or the vesting or transfer of restricted stock or securities acquired

respect to such stock or securities, the Company may withhold taxes in respect
of amounts that constitute compensation includable in gross income. The
Committee in its discretion may condition (i) the exercise of an option, or (ii)
the vesting or transferability of restricted stock or securities acquired by
exercising an option, on the optionee's making satisfactory arrangement for such
withholding. Such arrangement may include payment by the optionee in cash or by
check of the amount of the withholding taxes or, at the discretion of the
Committee, by the optionee's delivery of previously held shares of Common Stock
or the withholding of shares from the shares of Common Stock otherwise
deliverable upon exercise of an option, with such shares in each case having an
aggregate fair market value equal to the amount of such withholding taxes.

         (c) Termination. (1) Any unvested or unexercised option granted
hereunder shall terminate and become void at midnight on the thirtieth (30th)
day after the Optionee's employment with the Company is terminated for any
reason other than disability, death, or retirement with the consent of the

during the period ending one hundred eighty (180) days after the date of
termination of employment, but in no event later than the specified expiration
date of the option.

                  For purposes of this Agreement, the Optionee's employment
shall always be deemed to have been terminated due to disability if (a) the
Optionee's employment is terminated by either the Company or the Optionee; (b)
at the time of such termination, the Optionee is unable to work due to sickness

perform any gainful employment.

                  (3) In the event the employment of the Optionee terminates by

<PAGE>   4
the option.

                  (4) For purposes of this Agreement, a transfer of the Employee
between the parent Company and a subsidiary company, or between subsidiary
companies, shall not be deemed a termination of employment.

         Section 3. Limitations on Right to Exercise Option. Notwithstanding
anything elsewhere in this Option Agreement to the contrary, except the
provisions of Section 2(c), the right to exercise this option shall be subject
to the following limitations:

         (a) This option may not be exercised unless the Optionee, at the time
he exercises this option, is an employee of one or more of the Company, a parent
corporation or a subsidiary of the Company and has been such an employee at all
times since the date of this Agreement. If this option shall be assumed or a new
option substituted therefor as a result of a corporate merger, consolidation,
acquisition of property or stock, separation, reorganization, or liquidation,
then employment by such assuming or substituting corporation (hereinafter called
the "Successor Corporation") or by a parent corporation or a subsidiary thereof
shall be considered for purposes of this option to be employment by the Company.

         (b) This option must be exercised for a minimum of one hundred (100)
shares, or for all of the shares then purchasable hereunder if less than one
hundred (100) shares, and no fractional shares may be purchased under this
option.
<PAGE>   5
         Section 4.           Exercise of Option.

         (a) Method of Exercise of Option. This option may be exercised by
giving written notice to the Company by mail or in person addressed to
Treasurer, Hadco Corporation, 12A Manor Parkway, Salem, New Hampshire 03079,
specifying the number of Option Shares being purchased, accompanied by payment
of the full option price of the shares being purchased. A copy of such notice
shall be provided to Berlin, Hamilton & Dahmen, 73 Tremont Street, Boston,
Massachusetts 02108, or to such other counsel as the Company may hereafter
designate, and to the Bank of Boston, Shareholder Services Division, Post Office
Box 644, Boston, Massachusetts 02102, or to such other Stock Transfer Agent as
the Company may hereafter designate. The price for the Option Shares shall be
payable (a) in U.S. Dollars in cash, or (b) through delivery of shares of Common
Stock having a fair market value equal as of the date of the exercise to the
cash exercise price of the option, or (c) consistent with applicable law,
through the delivery of an assignment to the Company of a sufficient amount of
the proceeds from the sale of the Common Stock acquired upon exercise of the
option and an authorization to the broker or selling agent to pay that amount to
the Company, which sale shall be at the participant's direction at the time of
exercise, or (d) by any combination of (a), (b) and (c) above. The holder of an
option shall not have any rights of a shareholder with respect to the shares
covered by the option, except to the 
<PAGE>   6
extent that one or more certificates for such shares shall be delivered to him
upon the due exercise of the option.

         (b) Delivery of Stock Certificates Upon Exercise. Upon each exercise of
this option and the satisfaction of all conditions set forth in the option, the
Transfer Agent shall, on behalf of the Company, mail or deliver to the Optionee,
as promptly as practicable, a stock certificate or certificates representing the
Option Shares then being purchased. The Company will pay all stamp taxes due or
payable in connection with the issuance of the certificates. Such certificates
may bear statements relating to the non-registration of such shares under the
Securities Act of 1933, and the rights, privileges and limitations of Common
Stock, par value $0.05, of the Company, as set forth in the Restated Articles of
Organization, as amended.

         (c) Restrictions on Issuance of Shares. Notwithstanding the foregoing,
the Company shall not be obligated to deliver any such certificate or
certificates upon exercise of this option until one of the following conditions
shall be satisfied: (i) The shares with respect to which the option has been
exercised are at the time of the issue of such shares effectively registered
under applicable Federal and State securities acts as now in force or hereafter
amended; or (ii) Counsel for the Company shall have given an opinion that such
shares are exempt from registration under applicable Federal and State
securities acts as now in force or hereafter amended; and until the 
<PAGE>   7
Company is in compliance with all applicable laws and regulations, including 
without limitation all regulations required by any stock exchange upon which the
Company's outstanding Common Stock is then listed.

         The Company shall use its best efforts to bring about compliance with
the above conditions within a reasonable time, except that the Company shall be
under no obligation to cause a registration statement or a post-effective
amendment to any registration statement to be prepared at its expense solely for
the purpose of covering the issue of shares in respect of which any option may
be exercised.

         (d) Agreement to Purchase for Investment. By acceptance of this option,
the Optionee agrees that a purchase of shares under this option will be made for
investment and will not be made with a view to their distribution, as that term
issued in the Securities Act of 1933, as amended, unless in the opinion of
counsel for the Company such distribution is in compliance with or exempt from
registration and prospectus requirements of the Act. The Optionee agrees, if
necessary, to sign a certification to such effect at the time of exercising the
option and agrees that the certificate for the shares so purchased may be
inscribed with a legend to ensure compliance with the Securities Act of 1933 and
with any other applicable securities laws.

         Section 5. Adjustments Upon Changes in Capitalization.

         (a) In the event that the outstanding shares of the 
<PAGE>   8
Common Stock of the Company are changed into or exchanged for a different number
or kind of shares or other securities of the Company by reason of any
reorganization, recapitalization, reclassification, stock split-up, combination
of shares or dividends payable in capital stock, appropriate adjustments shall
be made in the number and kind of shares as to which outstanding options or
portions thereof then unexercised shall be exercisable, to the end that the
proportionate interest of the Optionee shall be maintained as before the
occurrence of such event. Such adjustment in outstanding options shall be made
without change in the total price applicable to the unexercised portion of such
options and with a corresponding adjustment in the option price per share.

         (b) Upon any sale of all or substantially all of the assets of the
Company, or upon any merger, consolidation or tender offer in respect of which
the stockholders holding all of the Company's outstanding voting securities
immediately prior to the consummation thereof hold less than 50% of all of the
Company's outstanding voting securities immediately after such consummation
(each of the foregoing sale, merger, consolidation or tender offer hereinafter
called an "Acquisition"), then the date upon which all then outstanding options
granted under the Plan become fully vested and exercisable shall be
automatically accelerated to occur immediately prior to the consummation of such
Acquisition; provided, however, that any such then 
<PAGE>   9
outstanding options which are not thereupon exercised in full immediately prior
to the consummation of such Acquisition shall thereupon terminate.

         (c) In the event of a recapitalization or reorganization of the Company
(other than a transaction described in subsections 5(a) and (b) above) pursuant
to which securities of the Company or of another corporation are issued with
respect to the outstanding shares of Common Stock, the Optionee upon exercising
this option shall be entitled to receive for the purchase price paid upon such
exercise the securities he or she would have received if he or she had exercised
such option prior to such recapitalization or reorganization. In the event of
the proposed dissolution or liquidation of the Company, the option will
terminate immediately prior to the consummation of such proposed action or at
such other time and subject to such other conditions as shall be determined by
the Committee. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares subject to the option. No
adjustments shall be made for dividends paid in cash or in property other than
securities of the Company. No fractional shares shall be issued and the Optionee
shall receive from the Company cash in lieu of such fractional shares. The
Committee or the Successor Board 
<PAGE>   10
shall determine the specific adjustments to be made under this Section 5 and,
subject to the Plan, its determination shall be conclusive.

         Section 6. Effect Upon Employment. The grant of this option confers no
right upon the Optionee with respect to the continuation of his employment with
the Company or a subsidiary of the Company. Nothing contained herein shall be
construed as interfering with or restricting the right of the Company or its
subsidiary or of the Optionee to terminate his employment at any time.

         Section 7. Non-Transferability. This option shall not be assignable or
transferable except by will or by the laws of descent and distribution. During
the lifetime of the Optionee, this option shall be exercisable only by the
Optionee. This option shall be null and void and without effect upon the
bankruptcy of the Optionee, or upon any attempted assignment or transfer,
including without limitation, any purported assignment, whether voluntary or by
operation of law, pledge, hypothecation or other disposition, attachment,
trustee process or similar process, whether legal or equitable, upon such
option.

         Section 8. Notices. Any notice permitted or required under this Option
Agreement shall be sufficient if made in writing and mailed, postage prepaid, or
delivered in hand to the parties as follows: (a) as to the Company, to its
Treasurer at the principal office of the Company; and (b) as to the Optionee, at
the address listed for the Optionee on 
<PAGE>   11
the books of the Company or the books of the Stock Transfer Agent, or (c) as to
either party, at such other address as shall be designated by the addressee in a
written notice to the other complying as to delivery with the terms of this
Section 8.

         Section 9. Governing Law. This Agreement shall be governed by, and
construed and enforced in accordance with, the substantive laws of the
Commonwealth of Massachusetts.

         Section 10. Modification of Outstanding Options. The Stock Option
Committee of the Company's Board of Directors or the Company's Board of
Directors may accelerate the exercisability of any outstanding option and may
authorize changes to any outstanding option with the consent of the Optionee
when and subject to such conditions as are deemed to be in the best interests of
the Company and in accordance with the purposes of the Company's November 29,
1995 Non-Qualified Stock Option Plan.

         Section 11. Entire Agreement. This Agreement contains the full and
complete understanding and agreement of the parties hereto as to the subject
matter hereof and may not be modified or amended, nor may any provisions hereof
be waived, except by a further written agreement duly signed by each of the
parties.

         Section 12. Binding Effect. This Agreement shall inure to the benefit
of and be binding upon the parties hereto and their respective heirs, executors,
administrators, representatives, successors and assigns; provided, however, 
<PAGE>   12
that as respects the Optionee, this Agreement is deemed to be personal in nature
and may not be assigned or transferred.

         Section 13. Interpretation and Construction. Any interpretation or
construction of this Option Agreement by the Company's Board of Directors, or a
duly authorized committee appointed by the Board, shall be final and conclusive.
The section headings are for convenience of reference only and shall not be
deemed germane to the interpretation or construction of this Option Agreement.

         Section 14. Survival. All representations, warranties and
acknowledgments made in this Agreement shall survive the delivery of the
certificate or certificates representing the shares purchased pursuant to the
exercise of the option granted herein.

         Section 15. Withholding Taxes. If the Company in its discretion
determines that it is obligated to withhold any tax in connection with the
exercise of this option, or in connection with the transfer of, or the lapse of
restrictions on, any Common Stock or other property acquired pursuant to this
option, the Optionee hereby agrees that the Company may withhold from the
Optionee's wages or other remuneration the appropriate amount of tax. At the
discretion of the Company, the amount required to be withheld may be withheld in
cash from such wages or other remuneration or in kind from the Common Stock or
other property otherwise deliverable to the Optionee on exercise 
<PAGE>   13
of this option. The Optionee further agrees that, if the Company does not
withhold any amount from the Optionee's wages or other remuneration sufficient
to satisfy the withholding obligation of the Company, the Optionee will make
reimbursement on demand, in cash, for the amount withheld.

         IN WITNESS WHEREOF, the parties have executed this Agreement on the

                            STOCK PURCHASE AGREEMENT

     This Stock Purchase Agreement (the "Agreement"), to be effective as of
March 20, 1998, by and between Hadco Corporation ("Hadco") and Frederick G.
McNamee, III, an individual ("Purchaser") .

     1. Terms of Purchase. Subject to the other terms and conditions of this
Agreement, the Purchaser hereby agrees to purchase from Hadco, and Hadco hereby
agrees to sell to the Purchaser, forty thousand (40,000) shares of the common
stock of Hadco, $0.05 par value (the "Shares"), for the sum of One Million Four
Hundred Eighty Thousand Dollars ($1,480,000.00), or $37.00 per share, based on
the fair market value of the Shares (measured as the average between the high
and low trading prices of Hadco's common stock on the last business day
immediately preceding the effective date set forth above). Payment for the
Shares shall be in lawful money of the United States of America in the form of
cash, check or similar negotiable instrument. Upon such payment and satisfaction
of all conditions set forth in this Agreement, Hadco's transfer agent,
BankBoston/Boston EquiServe Services, shall on behalf of Hadco, mail or deliver
to the Purchaser, as promptly as practicable, a stock certificate or
certificates representing the Shares being purchased.

     2. Representations and Warranties of Purchaser. As an inducement to Hadco
to sell the Shares to the Purchaser, the Purchaser represents and warrants to
Hadco as follows, intending that such representations and warranties will
survive the admission of the Purchaser as a stockholder of Hadco:

          (a) The Purchaser is over 21 years of age and is legally competent to
     execute this Agreement.

          (b) The Purchaser has carefully reviewed and understands the risks of
     an investment in Hadco, is able to bear the economic risks of an investment
     in Hadco, can withstand a complete loss of his investment in the Shares,
     can hold the Shares for an indefinite period of time and has the net worth
     to undertake these risks.

          (c) The Purchaser, either alone or together with the assistance of the
     Purchaser's own professional advisor or advisors, has the knowledge and
     experience in business and financial matters that make the Purchaser
     capable of reading and interpreting financial statements of and concerning
     Hadco and of evaluating the merits and risks of an investment in the
     Shares. The Purchaser is an "Accredited Investor" as such term is defined
     in Regulation D of the Securities Act of 1933, as amended (the "Securities
     Act").

          (d) The Purchaser understands that an investment in the Shares is
     highly speculative, but believes that an investment in the Shares is
     suitable for the Purchaser based upon his investment objectives and
     financial needs, and the Purchaser has adequate 


<PAGE>   2


                                      -2-


     means for providing for his current financial needs and personal
     contingencies and has no need for liquidity of investment with respect to
     the Shares.

          (e) The Purchaser is acquiring the Shares for purposes of long-term
     investment, for the personal account of the Purchaser, and with no present
     intention of reselling, distributing or otherwise transferring the Shares
     or any portion of the Shares, and the Purchaser has no contract,
     undertaking or arrangement with any person or entity to sell or transfer
     all or any portion of the Shares to that person or entity, or to have that
     person or entity sell for him all or any portion of the Shares, or to
     afford or allow any participation in the Shares by any other person or
     entity.

          (f) The Purchaser understands and acknowledges that the Shares will be
     lettered or restricted stock, that the Shares are being offered and sold
     under the exemption to registration provided in Section 3(b) of the
     Securities Act and Regulation D promulgated thereunder and/or Section 4(2)
     of the Securities Act, and that this transaction has not been reviewed or
     passed upon by any federal or state agency. The Purchaser further
     understands and acknowledges that each certificate of Shares issued in
     connection with this Agreement shall contain the following restrictive
     legends:

               1. "The Shares represented by this certificate are subject to
          restrictions on transfer contained in the terms and conditions of the
          Stock Purchase Agreement by and between Hadco Corporation and
          Frederick G. McNamee, III, dated March __, 1998."

               2. "The Shares represented by this certificate have not been
          registered under the Securities Act of 1933. These Shares have been
          acquired for investment and not with a view to distribution or resale,
          and may not be sold, mortgaged, pledged, hypothecated or otherwise
          transferred without an effective registration statement of such Shares
          under the Securities Act of 1933, or an opinion of counsel for Hadco
          Corporation that registration is not required under such Act."

          (g) The Purchaser realizes that (i) the purchase of the Shares is a
     long-term investment; (ii) the Purchaser must bear the economic risk of
     investment for an indefinite period of time because the Shares have not
     been registered and, therefore, cannot be sold unless they are subsequently
     registered or exemptions from registration are available; (iii) there
     presently is no public market for the Shares, and the Purchaser may not be
     able to liquidate his investment in the Shares in the event of an emergency
     or to pledge the Shares as collateral for loans; and (iv) the
     transferability of the Shares is restricted, and (A) requires the written
     consent of Hadco, (B) requires conformity with the restrictions contained
     in paragraph (f) above, (C) will be further restricted by legends placed on
     the certificate representing the Shares referring to the applicable
     restrictions on transferability, and (D) may be subject to a stop transfer
     order until such time as transfer 


<PAGE>   3


                                      -3-


     of the Shares may be effected without violation of all applicable state and
     federal securities laws.

          (h) The Purchaser has been furnished materials relating to Hadco (or
     these materials have been made available to the Purchaser), including the
     annual report of Hadco for its most recent fiscal year, the proxy statement
     used in connection with the annual meeting of Hadco following its most
     recent fiscal year, the reports filed with the Securities and Exchange
     Commission for the periods covering the most recent completed fiscal year
     of Hadco, all reports filed since the end of that year and any other
     materials that the Purchaser has requested.

          (i) The Purchaser has been given access to full and complete
     information regarding Hadco and has utilized that access to his
     satisfaction for the purpose of obtaining information concerning Hadco, an
     investment in the Shares and the terms and conditions of the offering of
     the Shares for the purpose of asking questions of, and receiving answers
     from, Hadco representatives concerning Hadco, an investment in the Shares
     and the terms and conditions of the offering, and for the purpose of
     obtaining any additional information (to the extent reasonably available)
     that is necessary to verify the information provided.

          (j) The Purchaser has obtained, in his judgment, sufficient
     information to understand the business in which Hadco is engaged and to
     evaluate the merits and risks of an investment in Hadco.

          (k) The Purchaser confirms that he has been advised that he should
     rely on his own professional accounting, tax, legal and financial advisors
     with respect to an investment in Hadco and a purchase of the Shares, and
     obtained, to the extent he deems necessary, the Purchaser's own personal
     professional advice with respect to both the risks inherent in an
     investment in the Shares and the suitability of an investment in the Shares
     in light of the Purchaser's financial condition and investment needs.

          (l) The Purchaser certifies, under the penalties of perjury, that he
     is NOT subject to the backup withholdings provisions of Section 3406 (a)
     (1) (c) of the Internal Revenue Code of 1986. The Purchaser understands
     that he would be subject to backup withholding if (i) he failed to furnish
     his Social Security number or taxpayer identification number in this
     Agreement; (ii) the Internal Revenue Service notified Hadco that the
     Purchaser furnished an incorrect Social Security number or taxpayer
     identification number; (iii) the Purchaser was notified that he is subject
     to backup withholding; or (iv) the Purchaser failed to certify that he is
     not subject to backup withholding or failed to certify his Social Security
     number or taxpayer identification number.

                                      -4-


          (m) The address set forth below is the Purchaser's true and correct
     residence, and he has no present intention of becoming a resident of any
     other state or jurisdiction.

          (n) All of the information that the Purchaser has furnished to Hadco,
     or that is set forth herein, or that is contained in any purchaser

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (this "Agreement"), to be effective as of the
Effective Time (as defined in an Agreement and Plan of Merger (the "Acquisition
Agreement") dated as of the date hereof (as it may be amended) among Hadco
Corporation, a Massachusetts corporation ("Hadco"), Hadco Acquisition Corp. II,
a Delaware corporation ("Sub"), and Continental Circuits Corp., a Delaware
corporation ("Continental")), by and between Hadco and Frederick G. McNamee,
III, an individual ("Employee").

         Whereas, Employee is currently the chief executive officer and
president of Continental; and

         Whereas, the Acquisition Agreement contemplates the acquisition by Sub
of all of the outstanding capital stock of Continental, with a subsequent merger
of Sub into Continental, and the renaming of the Surviving Corporation (as
defined in the Acquisition Agreement) to be Hadco Phoenix, Inc. ("Hadco
Phoenix"); and

         Whereas, in connection with the acquisition, Employee has agreed to
serve as an employee of Hadco upon the terms and conditions set forth herein.

         Now, therefore, in consideration of the premises and for good and
valuable consideration, the receipt and legal sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1. EMPLOYMENT AND DUTIES. Hadco agrees to employ Employee on a
full-time basis, subject to the terms and conditions provided herein, and
Employee agrees to accept such full-time employment upon said terms and
conditions. Employee's initial title shall be Senior Vice President, Hadco
Phoenix, in which capacity Employee shall have general responsibility for the
activities and operations of Hadco Phoenix and all of its direct wholly-owned
subsidiaries, subject to the direction and control of Hadco's chief executive
officer. Although Employee understands that his duties will include a
substantial amount of business travel, during the entire term of employment, he
shall be based in the Phoenix, Arizona, area, unless otherwise agreed between
the parties in the future. Employee's employment shall be subject to the
standard terms, conditions, and policies applicable to all Hadco employees, as
such terms, conditions and policies may exist from time to time.

         2. TERM. The term of employment under this Agreement (the "Term") shall
commence on the Effective Time and shall continue for a period of two years,
unless earlier terminated as set forth in Section 5 below.

         3. COMPENSATION.

            a. BASE SALARY. Hadco agrees to pay Employee a base salary, before
         deducting all applicable withholdings, at the annual rate of $235,000
         (the "Base Salary"), which shall be payable in accordance with Hadco's
         standard executive payroll policies as they may be revised from time to
         time. The Base Salary may be increased during the Term hereof at the
         discretion of the chief executive officer of Hadco.

            b. BONUS. Employee shall be eligible to participate in the bonus
         programs of Hadco applicable to senior executives, as such programs may
         exist from time to time.

            c. STOCK OPTIONS. Employee shall be granted non-qualified stock
         options to purchase 40,000 shares of Hadco common stock, pursuant to
         and subject to the terms and provisions of Hadco's Non-Qualified Stock
         Option Plan of November 29, 1995, at the fair market value of such
         stock as of the last business day immediately preceding the Effective
         Time. Such option shall be evidenced by a Stock Option Agreement in the
         form customarily utilized by Hadco for such grants.

                                      -2-


            d. BENEFITS. Employee shall be accorded such benefits as are
         customarily enjoyed by senior executives of Hadco.

         4. INVESTMENT. Employee agrees to purchase from Hadco, on the Effective
Time, 40,000 shares of Hadco common stock at the fair market value of such stock
(measured as the average between the high and low trading prices of Hadco's
common stock on the last business day immediately preceding the Effective Time),
which shares will not have been registered under the Securities Act of 1933, as
amended. Employee understands and agrees that such shares will not be salable on
the open market, and Employee represents and warrants that he is purchasing such
shares for investment purposes and not with a view to distribution, and that he
is an "Accredited Investor" (as such term is defined in Regulation D of the
Securities Act of 1933, as amended). Employee agrees that certificates
representing such shares shall bear appropriate restrictive legends, and further
agrees that the shares may be subject to a stop transfer order until such time
as transfer of the shares may be effected without violation of state or federal
securities laws.

         5. SEVERANCE. If, during the Term hereof, Employee's employment is
terminated by Hadco without cause, or is terminated by Employee for Good Reason
(as defined herein), Employee shall be paid his full Base Salary for the
remainder of the Term. For purposes of this Agreement, the following definitions
shall apply:

                           (a) CAUSE. Hadco shall have "cause" to terminate
                  Employee's employment in the event of (i) Employee's willful
                  and continued failure to substantially perform his duties
                  (other than any such failure resulting from incapacity due to
                  physical or mental illness), after a written demand for
                  substantial performance is delivered by Hadco which demand
                  specifically identifies the manner in which Employee has not
                  substantially performed his duties, or (ii)(x) Employee shall
                  have been guilty of any act or acts of dishonesty constituting
                  a felony, or (y) Employee shall have violated any provision of
                  any confidentiality, nondisclosure, assignment of invention,
                  noncompetition or similar agreement entered into by him in
                  connection with his employment by Hadco. For purposes of this
                  subsection, no act or failure to act on the part of Employee
                  shall be deemed "willful" unless done or omitted to be done by
                  Employee not in good faith and without reasonable belief that
                  his action or omission was in the best interest of Hadco.

                             (b) GOOD REASON. "Good Reason" shall mean, without
                  Employee's consent, the occurrence of the following:

                                    (i) any significant diminution in Employee's
                                    position, duties, responsibilities, power,
                                    title or office;

                                    (ii) any reduction in Employee's annual base
                                    salary; or

                                    (iii) any requirement by Hadco that the
                                    location at which Employee performs his
                                    principal duties be outside a radius of 30
                                    miles from Phoenix.

         6.       NON-COMPETITION; NON-SOLICITATION.

                          a. NON-COMPETE. Employee agrees that he will not,
         during the Term, directly or indirectly, engage in (whether as an
         officer, employee, consultant, director, proprietor, agent, partner or
         otherwise) or have any ownership interest in, or participate in the
         financing, operation, management or control of, any person, firm,
         corporation or business that engages in competition with Hadco or any
         of its subsidiaries or affiliates in the business of manufacture or
         sale of printed circuit boards or of other electronic interconnect
         products, or in the development of technologies for such businesses.
         The territory to which this restriction shall apply shall be worldwide.
         It is agreed that ownership of no more than 1% of the outstanding
         voting stock of a publicly traded corporation shall not constitute a
         violation of this provision.

                  b. CONFIDENTIAL INFORMATION. Employee acknowledges that
         Employee may receive, or contribute to the production of, Confidential
         Information. For purposes of this Agreement, Employee



<PAGE>   3

                                      -3-

         agrees that "Confidential Information" shall mean information or
         material proprietary to Hadco or any of its direct or indirect
         subsidiaries or designated as Confidential Information by Hadco and not
         generally known by non-Hadco personnel, which Employee develops or of
         or to which Employee may obtain knowledge or access through or as a
         result of Employee's relationship with Hadco or any of its direct or
         indirect subsidiaries (including information conceived, originated,
         discovered or developed in whole or in part by Employee). Confidential
         Information includes, but is not limited to, the following types of
         information and other information of a similar nature (whether or not
         reduced to writing) related to Hadco's business: discoveries,
         inventions, ideas, concepts, research, development, processes,
         procedures, "know-how", formulae, marketing techniques and materials,
         marketing and development plans, business plans, customer names and
         other information related to customers, price lists, pricing policies,
         methods of operation, financial information, employee compensation, and
         computer programs and systems. Confidential Information also includes
         any information described above which Hadco or any of its direct or
         indirect subsidiaries obtains from another party and which Hadco treats
         as proprietary or confidential, or designates as Confidential
         Information, whether or not owned by or developed by Hadco. Employee
         acknowledges that the Confidential Information derives independent
         economic value, actual or potential, from not being generally known to,
         and not being readily ascertainable by proper means by, other persons
         who can obtain economic value from its disclosure or use. Information
         publicly known without breach of this Agreement that is generally
         employed by the trade at or after the time Employee first learns of
         such information, or generic information or knowledge which Employee
         would have learned in the course of similar employment or work
         elsewhere in the trade, shall not be deemed part of the Confidential
         Information. Employee further agrees:

                           (1) To furnish Hadco on demand, at any time during or
         after employment, a complete list of the names and addresses of all
         present, former and potential suppliers, customers and other contacts
         gained while an employee of Hadco in Employee's possession, whether or
         not in the possession or within the knowledge of Hadco.

                           (2) That all notes, memoranda, electronic storage,
         documentation and records in any way incorporating or reflecting any
         Confidential Information shall belong exclusively to Hadco, and
         Employee agrees to turn over all copies of such materials in Employee's
         control to Hadco upon request or upon termination of Employee's
         employment with Hadco.

                           (3) That while employed by Hadco and thereafter
         Employee will hold in confidence and not directly or indirectly reveal,
         report, publish, disclose or transfer any of the Confidential
         Information to any person or entity, or utilize any of the Confidential
         Information for any purpose, except in the course of Employee's work
         for Hadco.

                           (4) That any idea in whole or in part conceived of or
         made by Employee during the term of his employment, consulting, or
         similar relationship with Hadco which relates directly or indirectly to
         Hadco's current or planned lines of business and is made through the
         use of any of the Confidential Information or any of Hadco equipment,
         facilities, trade secrets or time, or which results from any work
         performed by Employee for Hadco, shall belong exclusively to Hadco and
         shall be deemed a part of the Confidential Information for purposes of
         this Agreement. Employee hereby assigns and agrees to assign to Hadco
         all rights in and to such Confidential Information whether for purposes
         of obtaining patent or copyright protection or otherwise. Employee
         shall acknowledge and deliver to Hadco, without charge to Hadco (but at
         its expense) such written instruments and do such other acts, including
         giving testimony in support of Employee's authorship or inventorship,
         as the case may be, necessary in the opinion of Hadco to obtain patents
         or copyrights or to otherwise protect or vest in Hadco the entire right
         and title in and to the Confidential Information.

                  c. NON-SOLICITATION. During the Term and for a period of one
         year thereafter, Employee agrees that he shall not (for the purpose of
         or which results in competition with Hadco or any of its affiliates or
         subsidiaries) either solicit any persons or companies who were
         customers, clients, suppliers or business patronage of Hadco during the
         Term or prior thereto or of any of its predecessors, affiliates or



<PAGE>   4

                                      -4-

         subsidiaries or use any Confidential Information; nor will he solicit
         for any purpose the employment of any employees of Hadco or any of its
         affiliates or subsidiaries during the Term or for a period of one year
         thereafter.

                  d. INJUNCTIONS. It is agreed that the restrictions contained
         in this Section 6 are reasonable, but it is recognized that damages in
         the event of the breach of any of the restrictions will be difficult or
         impossible to ascertain; and, therefore, Employee agrees that, in
         addition to and without limiting any other right or remedy Hadco may
         have, Hadco shall have the right to an injunction against Employee
         issued by a court of competent jurisdiction enjoining any such breach
         without showing or proving any actual damage to Hadco.

                  e. PART OF CONSIDERATION. Employee also agrees, acknowledges,
         covenants, represents and warrants that he is fully and completely
         aware that, and further understands that, the foregoing restrictive
         covenants are an essential part of the consideration for Hadco entering
         into this Agreement and that Hadco is entering into this Agreement in
         full reliance on these acknowledgments, covenants, representations and
         warranties.

                  f. TIME AND TERRITORY REDUCTION. If the period of time and/or
         territory described above are held to be in any respect an unreasonable
         restriction, it is agreed that the court so holding may reduce the
         territory to which the restriction pertains or the period of time in
         which it operates or may reduce both such territory and such period, to
         the minimum extent necessary to render such provision enforceable.

                  g. APPLICABILITY TO SUBSIDIARIES. As used in this Section,
         Hadco shall mean and include Hadco Corporation and all or its direct or
         indirect subsidiaries.

                  h. SURVIVAL. The obligations described in this Section 6 shall
         survive any termination of this Agreement, except for a termination
         under Section 14 hereof, or any termination of the employment
         relationship created hereunder.

         7. GOVERNING LAW AND VENUE. Arizona law shall govern the construction
and enforcement of this Agreement and the parties agree that any litigation
pertaining to this Agreement shall be in courts located in Maricopa County,
Arizona.

         8. CONSTRUCTION. The language in all parts of this Agreement shall in
all cases be construed as a whole according to its fair meaning and not strictly
for nor against any party. The Section headings contained in this Agreement are
for reference purposes only and will not affect in any way the meaning or
interpretation of this Agreement. All terms used in one number or gender shall
be construed to include any other number or gender as the context may require.
The parties agree that each party has reviewed this Agreement and has had the
opportunity to have counsel review the same and that any rule of construction to
the effect that ambiguities are to be resolved against the drafting party shall
not apply in the interpretation of this Agreement or any amendment or any
exhibits thereof.

         9. NONDELEGABILITY OF EMPLOYEE'S RIGHTS AND HADCO ASSIGNMENT RIGHTS.
The obligations, rights and benefits of Employee hereunder are personal and may
not be delegated, assigned or transferred in any manner whatsoever, nor are such
obligations, rights or benefits subject to involuntary alienation, assignment or
transfer. This Agreement shall be assigned automatically to any entity merging
with or acquiring Hadco or its business.

         10. SEVERABILITY. If any term or provision of this Agreement is
declared by a court of competent jurisdiction to be invalid or unenforceable for
any reason, this Agreement shall remain in full force and effect, and either (a)
the invalid or unenforceable provision shall be modified to the minimum extent
necessary to make it valid and enforceable or (b) if such a modification is not
possible, this Agreement shall be interpreted as if such invalid or
unenforceable provision were not a part hereof.

         11. ATTORNEYS' FEES. Except as otherwise provided herein, if any party
hereto institutes an action or other




<PAGE>   5


                                      -5-


proceeding to enforce any rights arising out of this Agreement, the party
prevailing in such action or other proceeding shall be paid all reasonable costs
and attorneys' fees by the non-prevailing party, such fees to be set by the
court and not by a jury and to be included in any judgment entered in such
proceeding.

         12. NOTICES. All notices required or permitted hereunder shall be in
writing and shall be deemed duly given, upon receipt, if either personally
delivered, sent by certified mail, return receipt requested, or sent by a

         severally and unconditionally liable to fund its pro rata share (based
         upon each Bank's Commitment Percentage) of such Swing Line Loans on
         each Swing Line Settlement Date. Prior to each Swing Line Settlement,
         all payments or repayments of the principal and interest on Swing Line
         Loans shall be credited to the account of the Swing Line Lender. The
         Borrower shall have the right at its election, to repay the outstanding
         amount of the Swing Line Loans, as a whole or in part, at any time
         without penalty or premium, provided that any full or partial repayment
         of the outstanding amount of any Swing Line Loan that is a Fixed Rate
         Loan may be made only on the last day of the Interest Period relating
         thereto. The aggregate outstanding amount of Swing Line Loans advanced
         by the Swing Line Lender hereunder shall not exceed $10,000,000, and
         there shall not be more than four (4) Swing Line Loans outstanding at
         any one time.

                         2.9.2. SETTLEMENTS. (a) The Banks shall effect Swing
          Line Settlements on each Swing Line Settlement Date. One (1) Business
          Day prior to each such Swing Line Settlement Date, the Agent or the
          Swing Line Lender shall give telephonic or facsimile notice to the
          Banks of (i) the respective outstanding amount of Loans made by each
          Bank as at the close of business on the prior day, (ii) the amount
          that any Bank, as applicable (the "Swing Line Settling Bank"), shall
          pay to effect a Swing Line Settlement (the "Swing Line Settlement
          Amount") and (iii) the portion (if any) of the aggregate Swing Line
          Settlement Amount to be paid to each Bank. A statement of the Agent or
          the Swing Line Lender submitted to the Banks with respect to any
          amounts owing hereunder shall be prima facie evidence of the amount
          due and owing. Each Swing Line Settling Bank shall, not later than
          1:00 p.m. (Boston time) on each Swing Line Settlement Date, effect a
          wire transfer of immediately available funds to the Agent at the
          Agent's Head Office in the amount of such Bank's Swing Line Settlement
          Amount. The Agent shall, as promptly as practicable during normal
          business hours on each Swing Line Settlement Date, effect a
<PAGE>   9
                                      -9-


         wire transfer of immediately available funds to the Swing Line Lender
         of the Swing Line Settlement Amount to be paid to the Swing Line
         Lender.

                  (b) All funds advanced by any Bank as a Swing Line Settling
         Bank pursuant to this Section 2.9.2 shall for all purposes be treated
         as a Loan made by such Swing Line Settling Bank to the Borrower, and
         all funds received by any Bank pursuant to this Section 2.9.2 shall for
         all purposes be treated as repayment of amounts owed by the Borrower
         with respect to Loans made by such Bank. In the event that any
         bankruptcy, reorganization, liquidation, receivership or similar cases
         or proceedings, in which the Borrower is a debtor prevent a Settling
         Bank from making a Loan to effect a Settlement as contemplated hereby,
         such Settling Bank will make such dispositions and arrangements with
         the other Banks with respect to such Loans, either by way of purchase
         of participations, distributions, pro tanto assignment of claims,
         subrogation or otherwise as shall result in each Bank's share of the
         outstanding Loans (including the Swing Line Loans) being equal, as
         nearly as may be, to such Bank's Commitment Percentage of the
         outstanding amount of the Loans. Whenever, at any time after the Swing
         Line Lender has received from any Bank such Bank's participating
         interest in a Swing Line Loan pursuant to the terms hereof, the Swing
         Line Lender receives any payment on account thereof, the Swing Line
         Lender will distribute to such Bank its participating interest in such
         amount (appropriately adjusted, in the case of interest payments, to
         reflect the period of time during which such Bank's participating
         interest was outstanding and funded) in like funds as received;
         provided, however, that in the event that such payment received by the
         Swing Line Lender is required to be returned, such Bank will return to
         the Swing Line Lender any portion thereof previously distributed by the
         Swing Line Lender to it in like funds as such payment is required to be
         returned by the Swing Line Lender.

                         2.9.3. FUNDING PROCEDURES. (a) The Agent may (unless
          notified to the contrary by any Swing Line Settling Bank by 12:00 noon
          (Boston time) one (1) Business Day prior to the Settlement Date)
          assume that each Swing Line Settling Bank has made available (or will
          make available by the time specified in Section 2.9.2 to the Agent its
          Swing Line Settlement Amount, and the Agent may (but shall not be
          required to), in reliance upon such assumption, make available to the
          Swing Line Lender the aggregate Swing Line Settlement Amount. If the
          Swing Line Settlement Amount of such Swing Line Settling Bank is made
          available to the Agent by such Swing Line Settling Bank on a date
          after such Swing Line Settlement Date, such Swing Line Settling Bank
          shall pay the Agent on demand an amount equal to the product of (i)
          the average, computed for the period referred to in clause (iii)
          below, of the weighted average annual interest rate paid by the Agent
          for federal funds acquired by the Agent during each day included in
          such period times (ii) the Swing Line Settlement Amount times (iii) a
          fraction, the numerator of which is the number of days that elapse
          from and including such
<PAGE>   10
                                      -10-


         Swing Line Settlement Date to but not including the date on which the
         Swing Line Settlement Amount shall become immediately available to the
         Agent, and the denominator of which is 360, as the case may be. Upon
         payment of such amount, the Swing Line Settling Bank shall be deemed to
         have delivered its Swing Line Settlement Amount on the Swing Line
         Settlement Date and shall become entitled to interest payable by the
         Borrower with respect to such Bank's Swing Line Settlement Amount as if
         such share were delivered on the Swing Line Settlement Date. If the
         Swing Line Settlement Amount is not in fact made available to the Agent
         by the Swing Line Settling Bank within three (3) Business Days of such
         Swing Line Settlement Date, the Agent shall be entitled to recover such
         amount from the Borrower, with interest thereon at the Base Rate,
         provided that any such payment by the Borrower hereunder shall be
         without prejudice to any rights that the Borrower may have against the
         Swing Line Settling Bank which did not fund its required portion of the
         applicable Swing Line Loan. In the event that any Swing Line Settling
         Bank fails to make such Swing Line Settlement available to the Agent
         within one (1) Business Day following the Swing Line Settlement Date,
         the Agent will endeavor to provide to the Borrower notice of such
         failure, provided, a failure by the Agent to so provide such notice
         shall not affect the Agent's rights under this Section 2.9.3.

                  (b) After any Swing Line Settlement Date, any payment by the
         Borrower of Swing Line Loans hereunder shall be allocated among the
         Banks, in amounts determined so as to provide that after such
         application and the related Swing Line Settlement, the outstanding
         amount of Loans of each Bank equals, as nearly as practicable, such
         Bank's Commitment Percentage of the aggregate amount of Loans. The
         Swing Line Lender will notify the Agent promptly following each advance
         of a Swing Line Loan or any repayment with respect thereto. The failure
         or refusal of any Settling Bank to make available to the Agent at the
         aforesaid time and place on any Settlement Date the amount of such
         Settling Bank's Settlement Amount shall not (i) relieve any other
         Settling Bank from its several obligations hereunder to make available
         to the Agent the amount of such other Settling Bank's Settlement Amount
         or (ii) impose upon any Bank, other than the Settling Bank so failing
         or refusing, any liability with respect to such failure or refusal or
         otherwise increase the Commitment of such other Bank. Each Bank
         severally agrees that its obligation to make available to the Swing
         Line Lender its refunding or participation amounts as described above
         shall (except to the extent expressly set forth in this Section 2.9) be
         absolute and unconditional and shall not be affected by any
         circumstance, including (v) any set-off, counterclaim, recoupment,
         defense or other right which such Bank may have against the Swing Line
         Lender, the Borrower or any other Person for any reason whatsoever, (w)
         the occurrence or continuance of any Default or Event of Default, the
         termination of the Commitments or any other condition precedent
         whatsoever, (x) any adverse change in the condition (financial or
         otherwise) of the Borrower or
<PAGE>   11
                                      -11-


         any of its Subsidiaries or any other Person, (y) any breach of any of
         the Loan Documents by the Borrower or any of its Subsidiaries or any
         other Bank, or (z) any other circumstance, happening or event, whether
         or not similar to any of the foregoing."

immediately preceding sentence shall be applied: first, to the Swing Line
Loans; second, to any Unpaid Reimbursement Obligations; third, to the Loans
which are not Swing Line Loans; and fourth, to provide to the Agent cash
collateral for Reimbursement Obligations as contemplated by Section 4.2(b) and

Line Lender, in proportion, as nearly as practicable, to each Reimbursement
Obligation or, as the case may be, the respective unpaid principal amount of
each Bank's Revolving Credit Note or, as the case may be, the Swing Line

                                 SWING LINE NOTE

$10,000,000                                                  as of May 11, 1998


         FOR VALUE RECEIVED, the undersigned HADCO CORPORATION, a Massachusetts
corporation (the "Borrower"), hereby promises to pay to the order of BANKBOSTON,
N.A., a national banking association (the "Bank") at the Agent's Head Office (as
defined in the Credit Agreement referred to below):

                  (a) on the Revolving Credit Loan Maturity Date, the principal
         amount of TEN MILLION DOLLARS ($10,000,000) or, if less, the aggregate
         unpaid principal amount of Swing Line Loans advanced by the Bank to the
         Borrower pursuant to the Amended and Restated Revolving Credit
         Agreement dated as of December 8, 1997 (as amended and in effect from
         time to time, the "Credit Agreement"), among the Borrower, the Bank,
         BankBoston, N.A., as Agent, and other parties thereto;

                  (b) the principal outstanding hereunder from time to time at
         the times provided in the Credit Agreement; and

                  (c) interest on the principal balance hereof from time to time
         outstanding from the date hereof through and including the Revolving
         Credit Maturity Date hereof at the times and at the rate provided in
         the Credit Agreement.

         This Note evidences borrowings under and has been issued by the
Borrower in accordance with the terms of the Credit Agreement. The Bank and any
holder hereof is entitled to the benefits of the Credit Agreement and the other
Loan Documents, and may enforce the agreements of the Borrower contained
therein, and any holder hereof may exercise the respective remedies provided for
thereby or otherwise available in respect thereof, all in accordance with the
respective terms thereof. All capitalized terms used in this Note and not
otherwise defined herein shall have the same meanings herein as in the Credit
Agreement.

         The Borrower irrevocably authorizes the Bank to make or cause to be
made, at or about the time of the Drawdown Date of any Swing Line Loan or at the
time of receipt of any payment of principal of this Note, an appropriate
notation on the grid attached to this Note, or the continuation of such grid, or
any other similar record, including computer records, reflecting the making of
such Swing Line Loan or (as the case may be) the receipt of such payment. The
outstanding amount of the Swing Line Loans set forth on the grid attached to
this Note, or the continuation of such grid, or any other similar record,
including computer records, maintained by the Bank with respect to any Swing
Line Loans shall be prima facie evidence of the principal amount thereof owing
and unpaid to the Bank, but the failure to record, or any error in so recording,
any such amount on any such grid,
<PAGE>   24
                                      -2-


continuation or other record shall not limit or otherwise affect the obligation
of the Borrower hereunder or under the Credit Agreement to make payments of
principal of and interest on this Note when due.

         The Borrower has the right in certain circumstances and the obligation
under certain other circumstances to prepay the whole or part of the principal
of this Note on the terms and conditions specified in the Credit Agreement.

         If any one or more of the Events of Default shall occur, the entire
unpaid principal amount of this Note and all of the unpaid interest accrued
thereon may become or be declared due and payable in the manner and with the
effect provided in the Credit Agreement.

         No delay or omission on the part of the Bank or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Bank or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any further occasion.

         The Borrower and every endorser and guarantor of this Note or the
obligation represented hereby waives presentment, demand, notice, protest and
all other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement of this Note, and assents to any extension
or postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of collateral and to the addition or release
of any other party or person primarily or secondarily liable.

         THIS NOTE AND THE OBLIGATIONS OF THE BORROWER HEREUNDER SHALL FOR ALL
PURPOSES BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE
COMMONWEALTH OF MASSACHUSETTS (EXCLUDING THE LAWS APPLICABLE TO CONFLICTS OR
CHOICE OF LAW). THE BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS
NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY
FEDERAL COURT SITTING THEREIN AND THE CONSENT TO THE NONEXCLUSIVE JURISDICTION
OF SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON THE
BORROWER BY MAIL AT THE ADDRESS SPECIFIED IN SECTION 21 OF THE CREDIT AGREEMENT.
THE BORROWER HEREBY WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO
THE VENUE OF ANY SUCH SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN
INCONVENIENT COURT.

         This Note shall be deemed to take effect as a sealed instrument under
the laws of the Commonwealth of Massachusetts.

         IN WITNESS WHEREOF, the undersigned has caused this Amended and
Restated Swing Line Note to be signed in its corporate name and its corporate
seal to be impressed thereon by its duly authorized officer as of the day and
year first above written.
