ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.

     On April 26, 2002, Merrimac Industries, Inc. (the "Company") decided to
engage Ernst & Young LLP to serve as the Company's independent auditors for
2002. The Company's independent auditor since 1997 has been Arthur Andersen LLP.
This determination was approved by the Board of Directors of the Company upon
the recommendation of the Audit Committee of the Company. The ratification of
the appointment of Ernst & Young LLP will be considered by the Company's
stockholders at the 2002 Annual Meeting to be held on June 12, 2002.

     The Company dismissed Arthur Andersen LLP on April 27, 2002. The
determination to dismiss Arthur Andersen LLP was approved by the Board of
Directors of the Company upon the recommendation of the Audit Committee of the
Company.

     During the years ended December 29, 2001 and December 30, 2000 and through
April 26, 2002, there were no disagreements with Arthur Andersen LLP on any
matter of accounting principle or practice, financial statement disclosure, or
auditing scope or procedure which, if not resolved to Arthur Andersen LLP's
satisfaction, would have caused them to make reference to the subject matter of
the disagreement in connection with their reports.

     The audit reports of Arthur Andersen LLP on the Company's consolidated
financial statements as of and for the fiscal years ended December 29, 2001 and
December 30, 2000 did not contain any adverse opinion or disclaimer of opinion,
nor were they qualified or modified as to uncertainty, audit scope or accounting
principles.

     None of the reportable events described under Item 304(a)(1)(v) of
Regulation S-K occurred within the Company's two most recent fiscal years and
through April 26, 2002.

     The Company provided Arthur Andersen LLP with a copy of the foregoing
disclosures. Attached as Exhibit 16.3 is a copy of Arthur Andersen LLP's letter,
dated May 10, 2002, stating its agreement with such statements.

     During the years ended December 29, 2001 and December 30, 2000 and through
April 26, 2002, the Company did not consult Ernst & Young LLP regarding any
matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.
