AMENDMENT TO SECURITY AGREEMENT

THIS AMENDMENT TO SECURITY AGREEMENT (the Amendment) dated as of March
12, 2003, is by and between SIEMENS HEARING INSTRUMENTS, INC., a Delaware
corporation (Lender), with offices at 10 Constitution Avenue, Piscataway, New
Jersey 08855, and HearUSA, Inc.(formerly known as HEARX LTD.), a Delaware
corporation (Borrower), with offices at 1250 Northpoint Parkway, West Palm
Beach, Florida 33407.

Background

A.     The Lender and Borrower are parties to a Security Agreement dated as of
December 7, 2001 (the Security Agreement). Pursuant to the Security
Agreement, the Borrower granted the Lender a security interest in certain
assets of the Borrower, which was perfected pursuant to the filing of UCC
Financing Statements. The Security Agreement was entered into in connection
with certain commercial loan transactions of equal date therewith pursuant to
which Borrower executed and delivered to Lender a Credit Agreement (such
agreement, as it may be further amended, supplemented or otherwise modified
from time to time, being the Credit Agreement), pursuant to which Lender
extended certain loans to Borrower in the original principal amount of
$51,875,000.00, which were evidenced by certain promissory notes.

B.     As of the date of this Amendment, the Lender and Borrower will be
amending the Credit Agreement, to, among other things, provide for the
extension of a new term loan facility in the principal amount of $3,500,000.00,
which will be evidenced by a new Tranche E Note (the Tranche E Loan).

C.     In connection with the execution and delivery of the Tranche E Note and
the simultaneous amendment of various other related documents and agreements,
the parties have agreed to amend, modify and affirm the Security Agreement as
set forth in this Amendment.

D.     All capitalized terms not otherwise defined herein shall have the
meanings ascribed to such terms in the Security Agreement and the documents
referenced therein.

NOW, THEREFORE, in consideration of the mutual agreements contained herein
and other good and valuable consideration, the sufficiency and receipt of which
is hereby acknowledged, the parties agree as follows:
