Item 4. Changes in Registrant's Certifying Accountant.

On March 15, 2002, the Board of Directors of Abbott Laboratories ("Abbott") adopted the recommendation of its Audit Committee that Arthur Andersen LLP ("Andersen") be dismissed as Abbott's auditors. This will occur upon the later of: (i) the engagement of a new independent public accounting firm or (ii) the filing of Abbott's quarterly report on Securities and Exchange Commission Form 10-Q for the period ending March 31, 2002. A new independent public accounting firm has not yet been engaged to act as Abbott's auditors.

Andersen's reports on Abbott's consolidated financial statements for each of the years December 31, 2001 and 2000 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the years ended December 31, 2001 and 2000 and through the date hereof, there were no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Andersen's satisfaction, would have caused Andersen to make reference to the subject matter in connection with its report on Abbott's consolidated financial statements for such years; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

Abbott has provided Andersen with a copy of the foregoing statements. Attached as Exhibit 16 is a copy of Andersen's letter, dated April 1, 2002, stating its agreement with such statements.
