Catapult Communications Changes Accounting Firms to Reduce Expenses

Catapult Communications Corporation (NASDAQ: CATT) today announced that, in order to significantly reduce its accounting expenses, it has dismissed its previous independent registered public accounting firm, Deloitte & Touche LLP, and has engaged the firm of Stonefield Josephson, Inc. The Company has had no disagreements with Deloitte & Touche LLP during their tenure.

The expenses that the Company incurred in connection with the audit and internal control review work performed by Deloitte & Touche LLP in fiscal year 2007 totaled approximately $1,076,000, and the Company estimates that these expenses would approximate $985,000 for the current fiscal year without a change in accounting firms. The Company and its Audit Committee believe that, by engaging Stonefield Josephson, Inc. as the Company's independent registered public accounting firm for the current fiscal year, the Company will realize significant savings on these expenses without negatively affecting the quality of the audit and related services. Based on estimates from the two firms, the Company currently believes that the potential savings for fiscal 2008 from the change in firms will be in the range of 43% - 49%.
