ITEM 4.01   CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT





On September 13, 2005, based on a recommendation of the Audit Committee of the Board of Directors of Chyron Corporation ("Chyron"), and the approval of the Board of Directors, Chyron Corporation, Administrator (the "Administrator") of the Chyron Corporation Employees' 401(k) Plan (the "401k Plan"), dismissed PricewaterhouseCoopers LLP ("PwC") as its independent registered public accounting firm of the 401k Plan. The reports of PwC on the 401k Plan financial statements as of and for the fiscal years ended December 31, 2004 and 2003 did not contain an adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle. During the fiscal years ended December 31, 2004 and 2003 and through September 13, 2005, there were no disagreements with PwC on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused it to make reference thereto in its reports on the financial statements for such years. During the fiscal years ended December 31, 2004 and 2003 and through September 13, 2005, there have been no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.  The Administrator requested that PwC furnish it with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of such letter, dated September 16, 2005, is filed as Exhibit 16.1 to this Form 8-K.



Also on September 13, 2005, based on the recommendation of the Audit Committee of the Board of Directors of Chyron, and the approval of the Board of Directors, the Administrator engaged BDO Seidman, LLP ("BDO") as the new independent registered public accounting firm for the 401k Plan. During the 401k Plan's two most recent fiscal years and through September 13, 2005 the Administrator has not consulted with BDO regarding either: (i) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the 401k Plan's financial statements, and neither a written report was provided to the Administrator nor was oral advice provided to it that BDO concluded was an important factor considered by the Administrator in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
