                        Report of Independent Accountants


October 30, 1998

To the Committee on Employee Benefits of the
GenRad, Inc. Choice Investment Plan - Part I and Part II

We have audited the accompanying statement of net assets available for plan
benefits of the GenRad, Inc. Choice Investment Plan - Part I and Part II (the
"Plan") as of December 31, 1997 and 1996 and the related statement of changes in
net assets available for plan benefits for the year ended December 31, 1997.
These financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our report dated October 2, 1998, we were unable to, and did not, express an
opinion on the statement of net assets available for plan benefits as of
December 31, 1997 and 1996 and the related statement of changes in net assets
available for plan benefits for the year ended December 31, 1997 because, at the
instruction of the plan administrator, we did not perform any auditing
procedures with respect to the information summarized in Note 6 in those
financial statements. The plan administrator has now instructed us to perform,
and we did perform, an audit of the statement of net assets available for plan
benefits as of December 31, 1997 and 1996 and the related statement of changes
in net assets available for plan benefits for the year ended December 31, 1997
in accordance with generally accepted auditing standards. Accordingly, we are
now able to express an opinion on those financial statements.

In our opinion, the financial statements referred to in the first paragraph of
this report present fairly, in all material respects, the net assets available
for plan benefits of the Plan as of December 31, 1997 and 1996 and the changes
in net assets available for plan benefits for the year ended December 31, 1997
in conformity with generally accepted accounting principles.


                                       1





To the Committee on Employee Benefits of the
GenRad, Inc. Choice Investment Plan - Part I and Part II
October 30, 1998



Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The additional information included in
Schedules I, II and III is presented for purposes of additional analysis and is
not a required part of the basic financial statements but is additional
information required by ERISA. The Fund information in the statement of changes
in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the changes in net assets available
for plan benefits of each fund. Schedules I, II and III and the Fund Information
have been subjected to the auditing procedures applied in the audits of the
basic financial statements and, in our opinion, are fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.

GenRad, Inc.
Choice Investment Plan - Part I and Part II
Notes to Financial Statements
- --------------------------------------------------------------------------------

1.       Description of the Plan

         The following description of the GenRad, Inc. (the "Company") Choice
         Investment Plan - Part I and Part II (the "Plan") provides only general
         information. Participants should refer to the Plan Agreement for a more
         complete description of the Plan's provisions.

         General
         The Plan is a defined contribution plan, qualified under Section 401(k)
         of the U.S. Internal Revenue Code ("IRC"), which provides retirement
         benefits to employees of the Company who have completed at least one
         month of service with the Company or any of its subsidiaries. The Plan
         was established on December 31, 1943 and has been amended from time to
         time. It is subject to the provisions of the Employee Retirement Income
         Security Act of 1974 ("ERISA").

         Contributions
         Participants may contribute up to 15% of their annual compensation to
         the extent that the contributions comply with IRC limitations. These
         contributions are not subject to federal income taxes until withdrawn,
         in accordance with Section 401(k) of the IRC. The Company matches 50%
         of employee contributions, up to a maximum of 6% of compensation paid.
         The Plan also includes a profit-sharing trust, whereby the Company may
         make a contribution each year from its consolidated current or
         accumulated earnings in an amount determined by the Board of Directors
         on or before the last day of the Company's fiscal year. No
         contributions were made to the profit-sharing trust during 1997.

         Effective July 1, 1998, the Company changed its matching policy to 50%
         of employee contributions, up to a maximum of 10% of compensation paid.

         Participant Accounts
         Each participant is assigned an individual account with only their
         account's investment income, realized and unrealized investment gains
         or losses allocated to them. Administrative expenses are charged to
         each participant's account on a quarterly basis totalling $20 annually.

         Vesting
         Participants who were employees on or prior to December 31, 1995 are
         fully vested in all employer and employee voluntary contributions plus
         actual earnings thereon upon entering the Plan. Participants who became
         employees subsequent to December 31, 1995 are fully vested in all
         employee contributions and earnings thereon upon entering the Plan.
         Company contributions and related earnings for these participants,
         however, vest at a rate of 25% per year.

         Retirement, Terminations and Disbursements
         In case of normal retirement, retirement due to permanent disability or
         termination of employment, participants may elect to receive the value
         of their accumulated Plan benefits in a lump sum, in accordance with
         the provisions of the Plan. In the event that a participant dies before
         retirement, the beneficiary will receive the value of the participant's
         accumulated Plan benefits in a lump-sum distribution, less the value of
         outstanding loans made to the participant.

Choice Investment Plan - Part I and Part II
Notes to Financial Statements
- --------------------------------------------------------------------------------

         Participants qualifying for a hardship withdrawal may receive all or a
         portion of their contributions, plus investment income earned thereon,
         but not more than the amount necessary to meet the financial hardship.

         Administration
         The Plan is administered by an administrative committee appointed by
         the Company. All funds in the Plan are held in trust by Vanguard
         Fiduciary Trust Company (the "Trustee").

         The Plan offers eleven investment options selected by the participants.
         In addition, the Plan maintains a 401(k) loan account for participant
         loans.

         Forfeitures
         Forfeited balances are used to reduce future employer contributions.

         Rollover
         Employees commencing participation in the Plan may elect to transfer to
         the Plan any amounts distributed from a previous qualified plan within
         60 days of receiving such distribution.


2.       Summary of Significant Accounting Policies

         Basis of Presentation
         The Plan's financial statements have been presented on the accrual
         basis of accounting.

         Reclassifications
         Certain reclassifications were made to the 1996 financial statements to
         conform to the 1997 presentation.

         Plan Expenses
         Administrative expenses of the Plan are paid by the Plan to a maximum
         of $20 per participant annually, and are reflected in the accompanying
         statement of changes in net assets available for plan benefits.
         Excess administrative expenses are paid by the Company.

         Valuation of Investments
         Investments are stated at fair value. The fair value of the shares
         owned by the Plan in mutual funds is based on the net asset value on
         the last business day of the Plan year. GenRad, Inc. common stock is
         valued at quoted market prices. Loans receivable from participants are
         recorded at cost plus accrued interest, which approximates fair value.

         Use of Estimates
         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of net assets
         available for plan benefits. Actual results could differ from those
         reported.

- --------------------------------------------------------------------------------

         Accounting Method
         Security transactions are accounted for on the date securities are
         purchased or sold (trade date). Dividend income is recorded on the
         ex-dividend date. Interest income is recognized when earned. Net gains
         and losses from securities transactions are computed using the average
         cost method based on the beginning market value. Contributions are
         recognized based on payroll dates and accrued if applicable.


3.       Loans Receivable From Participants

         The loans to participants bear interest at the prime rate and are due
         at various dates, not to exceed five years from the date of issuance
         unless the proceeds were used to construct or rehabilitate the
         participant's primary residence, in which case the loan repayment
         period shall not exceed 15 years.

         Participants are allowed to borrow up to 50% of their investment
         balances, not to exceed $50,000.


4.       Federal Income Taxes

         The Internal Revenue Service has determined and informed the Company by
         a letter dated July 3, 1995 that the Plan and related trust are
         designed in accordance with applicable sections of the IRC. The Plan
         has since been amended. A new letter has not been requested. However,
         management has asserted the Plan and its operations are in accordance
         with the applicable requirements of the IRC.


5.       Plan Termination

         Although it has not expressed any intent to do so, the Company has the
         right under the Plan to discontinue its contributions at any time and
         to terminate the Plan subject to the provisions of ERISA. In the event
         of Plan termination, participants will receive 100% of their account
         balances.
