CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT On March 11, 1999, Techniclone Corporation, a Delaware corporation (the "Company"), dismissed Deloitte & Touche LLP as the Company's principal independent public accountants. The reports of Deloitte & Touche LLP on the Company's financial statements for the past two years contained no adverse opinion and no disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope or accounting principles, except that the report of Deloitte & Touche LLP dated June 15, 1998, except for Note 12, as to which the date is July 17, 1998, appearing in the Company's Annual Report on Form 10-K for the year ended April 30, 1998, expressed an unqualified opinion and included an explanatory paragraph regarding substantial doubt about the Company's ability to continue as a going concern. The Company's decision to dismiss Deloitte & Touche LLP as its principal independent accountants was approved by the Company's Board of Directors. In the Company's two most recent fiscal years and the subsequent interim periods preceding the dismissal of Deloitte & Touche LLP, there were no disagreements with Deloitte & Touche LLP on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte & Touche LLP, would have caused Deloitte & Touche LLP to make a reference to the subject matter of the disagreement in connection with the reports of Deloitte & Touche LLP. The Company is furnishing herewith a letter addressed to the Securities and Exchange Commission from Deloitte & Touche LLP pursuant to Item 304(a)(3) of Regulation S-K, which letter is attached hereto as Exhibit A.
