     The following terms and conditions shall apply to this Note:

     Section 1. Payments of Principal and Interest.

          (a) Interest Only Payments. On each Payment Date beginning on March 25, 2004, and ending on December 25, 2005, the Company shall pay to the Holder all interest accrued to date on the entire Principal Amount of this Note (“Interest Amount”), in accordance with this Section 1.

          (b) Quarterly Payments. On each Payment Date beginning on March 25, 2006, the Company shall repay one-twelfth (1/12) of the original Principal Amount, together with interest accrued but unpaid on that date (collectively, “Quarterly Amount”), in accordance with this Section 1.

          (c) Cash or Common Stock. Subject to the terms hereof, the Company shall have the right to satisfy payment of the Interest Amount or Quarterly Amount in full on each Payment Date either in cash or in shares of Common Stock (but not both) at the Company’s option. If the Company elects or is required to pay any Interest Amount or Quarterly Amount in cash on a Payment Date, then on such Payment Date the Company shall pay to the Holder an amount equal to such Interest Amount or Quarterly Amount in satisfaction of such obligation. If the Company elects or is required to pay any Interest Amount or Quarterly Amount in shares of Common Stock, the number of such shares to be issued for such Payment Date shall be the number determined by dividing (x) the Interest Amount or Quarterly Amount, as the case may be, by (y) the Market Price, as applicable, as of such Payment Date. Such shares shall be issued and delivered within five (5) Trading Days following such Payment Date and shall be duly authorized, validly issued, fully paid, non-assessable and free and clear of all encumbrances. If any Holder does not receive the requisite number of shares of Common Stock in the form required above within such three Trading Day period, the Holder shall have the option of either (a) requiring the Company to issue and deliver all or a portion of such shares or (b) canceling such election to pay such Interest Amount or Quarterly Amount in Common Stock (in whole or in part), in which case the Company shall immediately pay in cash the full such Interest Amount or Quarterly Amount due hereunder or such portion as the Holder specifies is to be paid in cash instead of Common Stock. Except as otherwise provided in this Section 1, all holders of Notes must be treated the same with respect to such payment of the Interest Amount and Quarterly Amount in shares of Common Stock.

          (d) No Payment in Stock. Notwithstanding anything to the contrary herein, the Company shall be prohibited from paying the Interest Amount or Quarterly Amount in shares of Common Stock (and must deliver cash in respect thereof) on the applicable Payment Date if at any time from the Payment Date until the time at which the Holders receive such shares (i) there fails to exist Effective Registration, or (ii) the Company is subject to any Bankruptcy Event, unless otherwise waived in writing by the Holder in whole or in part at the Holder’s option.

          (e) Ownership/Issuance Limitations. Notwithstanding anything to the contrary herein, the Company shall be prohibited from paying the Interest Amount or Quarterly Amount in shares of Common Stock (and must deliver cash in respect thereof) on the applicable Payment Date to the extent, and only to the extent, that such payment in shares of Common Stock would result in the Holder hereof exceeding the limitations contained in Section 3(i) below. In such

5

event, then the Company on the Payment Date shall pay such portion of the Interest Amount or Quarterly Amount, as the case may be, in shares of Common Stock as may be effected without exceeding such limitations, and (ii) if such stock payment cannot be made only because it would violate Section 3(i) below, the Payment Date for the balance of the Interest Amount or Quarterly Amount, as the case may be, shall be extended until such time as such stock payment can be made without violating Section 3(i), or such balance shall be paid in cash. If any portion of any Quarterly Amount remains unpaid as of the Maturity Date hereof, such amount shall be repaid in cash on the Maturity Date.

          (f) Deemed Conversions. Any payment of the Quarterly Amount in shares of Common Stock pursuant to the terms hereof shall constitute and be deemed a conversion of such portion of the Principal Amount of this Note for all purposes under this Note and the other Agreements (except that such conversion shall be at the Market Price and except as otherwise provided herein).

          (g) Certain Additional Payments by the Company. Any payment by the Company to the Holder hereunder, whether for principal, interest or otherwise, shall not be subject to any deduction, withholding or offset for any reason whatsoever except to the extent required by law, and the Company represents that to its best knowledge no deduction, withholding or offset is so required for any tax or any other reason.

     Section 2. Subordinated/Subsequent Debt. The Notes are and shall be subordinated to the debt owned by the Company to Siemens Hearing Instruments, Inc., pursuant to the agreements in effect on the Issuance Date. So long as any Principal Amount of Notes is outstanding, the Company and its subsidiaries shall not directly or indirectly, without the affirmative vote of the holders of at least 75% of the outstanding Principal Amount of the Notes then outstanding, incur or permit to exist additional indebtedness which is senior to the Notes, or incur, assume or permit to exist any lien, mortgage, security interest or encumbrance (other than statutory liens imposed by law incurred in the ordinary course of business for sums not yet delinquent or being contested in good faith, if such reserve or other appropriate provision, if any, as shall be required by GAAP shall have been made in respect thereof) on any of its assets, except for indebtedness and liens to Siemens Hearing Instruments, Inc. pursuant to the agreements currently in effect on the Issuance Date and except for capital leases, financing for equipment and purchase money security interests.

     Section 3. Conversion.

          (a) Conversion Right. Subject to the terms hereof and restrictions and limitations contained herein, the Holder shall have the right, at such Holder’s option, at any time and from time to time after the second anniversary of the Issuance Date to convert the outstanding Principal Amount under this Note in whole or in part by delivering to the Company a fully executed notice of conversion in the form of conversion notice attached hereto as Exhibit A (the “Conversion Notice”), which may be transmitted by facsimile. Notwithstanding anything to the contrary herein, this Note and the outstanding Principal Amount hereunder shall not be convertible into Common Stock to the extent that such conversion would result in the Holder hereof exceeding the limitations contained in, or otherwise violating the provisions of, Section 3(i) below. For clarification purposes, any conversions of the outstanding Principal Amount under this Note in part

6

pursuant to this Section 3(a) shall not affect the Company’s obligation to repay the Quarterly Amount as provided in Section 1 above.

          (b) Common Stock Issuance upon Conversion.

               (i) Conversion Date Procedures. Upon conversion of this Note pursuant to Section 3(a) above, the outstanding Principal Amount hereunder shall be converted into such number of fully paid, validly issued and non-assessable shares of Common Stock, free of any liens, claims and encumbrances, as is determined by dividing the outstanding Principal Amount being converted by the Conversion Price. The date of any Conversion Notice hereunder and any Payment Date shall be referred to herein as the “Conversion Date”. If a conversion under this Note cannot be effected in full in accordance with the terms hereof, or if the Holder is converting less than all of the outstanding Principal Amount hereunder pursuant to a Conversion Notice, the Company shall promptly deliver to the Holder (but no later than five Trading Days after the Conversion Date) a Note (containing the same terms as the Note herein) for such outstanding Principal Amount as has not been converted if this Note has been surrendered to the Company for partial conversion. The Holder shall surrender this Note to the Company upon any conversion. The Company shall return a Note of lesser principal amount, having taken the conversion amount out of the face amount of the surrender Note, if any.

               (ii) Stock Certificates or DWAC. The Company will deliver to the Holder not later than five (5) Trading Days after the Conversion Date, a certificate or certificates which shall be free of restrictive legends and trading restrictions, representing the number of shares of Common Stock being acquired upon the conversion of this Note. In lieu of delivering physical certificates representing the shares of Common Stock issuable upon conversion of this Note, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such shares issuable upon conversion to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) prime broker with DTC through its Deposit Withdrawal Agent Commission system (provided that the same time periods herein as for stock certificates shall apply). If in the case of any conversion hereunder, such certificate or certificates are not delivered to or as directed by the Holder by the fifth Trading Day after the Conversion Date, the Holder shall be entitled by written notice to the Company at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion, in which event the Company shall immediately return this Note tendered for conversion. If the Company fails to deliver to the Holder such certificate or certificates (or shares through DTC) pursuant to this Section 3(b) (free of any restrictions on transfer or legends, if such shares have been registered) in accordance herewith, prior to the sixth Trading Day after the Conversion Date, the Company shall pay to the Holder, in cash, an amount equal to 0.3% of the Principal Amount subject to such conversion for each trading day thereafter until such certificate(s) or shares through DTC are delivered to the Holder or until the conversation is rescinded by the Holder, whichever shall first occur.

          (c) Conversion Price Adjustments.

               (i) Stock Dividends, Splits and Combinations. If the Company, at any time while the Notes are outstanding (A) shall pay a stock dividend or otherwise make a distribution

7

or distributions on any equity securities (including instruments or securities convertible into or exchangeable for such equity securities) in shares of Common Stock, (B) subdivide outstanding Common Stock into a larger number of shares, or (C) combine outstanding Common Stock into a smaller number of shares, then the Conversion Price in effect immediately prior to such event shall be adjusted to a number equal to such Conversation Price multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding before such event and the denominator of which shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section 3(c)(i) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

               (ii) Distributions. If the Company or any of its subsidiaries, at any time while the Notes are outstanding, shall distribute to all holders of Common Stock evidences of its indebtedness or assets or cash or rights or warrants to subscribe for or purchase any security of the Company or any of its subsidiaries (excluding those referred to in Section 3(c)(i) above), then concurrently with such distributions to holders of Common Stock, the Company shall distribute to holders of the Notes the amount of such indebtedness, assets, cash or rights or warrants which the holders of Notes would have received had all their Notes been converted into Common Stock at the Conversion Price immediately prior to the record date for such distribution.

               (iii) Anti dilution Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Issuance Date, the Company issues or sells, or in accordance with this Section 3 is deemed to have issued or sold, any shares of Common Stock, with the exception of Excluded Issuances, for a consideration per share (the “New Securities Issuance Price”) less than the Conversion Price in effect immediately prior to such time (each such sale or issuance, a “Dilutive Issuance”), then concurrent with such Dilutive Issuance, the Conversion Price then in effect shall be reduced to an amount equal to the New Securities Issuance Price. For purposes of determining the adjusted Conversion Price under this Section 3, the following shall be applicable:

                    (A) Issuance of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option is less than the Conversion Price in effect immediately prior to such Dilutive Issuance, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 3(c)(iii)(A), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exchange or exercise of any Convertible Securities issuable upon exercise of such Option” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion, exchange or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock or of such

8

Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities.

                    (B) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise thereof is less than the Conversion Price in effect immediately prior to such Dilutive Issuance, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance of sale of such Convertible Securities for such price per share. For the purposes of this Section 3(c)(iii)(B), the “lowest price per share for which one share of Common Stock is issuable upon such conversion, exchange or exercise” shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the issuance or sale of the Convertible Security and upon the conversion, exchange or exercise of such Convertible Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion, exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other provisions of this Section 3(c), no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

                    (C) Change in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Price in effect at the time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 3(c)(iii)(C), if the terms of any Option or Convertible Security that was outstanding as of the Issuance Date are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an increase of the Conversion Price then in effect.

                    (D) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, then solely for purposes of this Section 6, the Options will be deemed to have been issued for a consideration of $0.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the gross amount received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except where such consideration consists of marketable securities, in which case the amount of consideration received by the Company will be

9

the arithmetic average of the Closing Sale Prices of such securities during the ten (10) consecutive trading days ending on the date of receipt of such securities. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the holders of at least 75% of the Outstanding Principal Amount of the Notes then outstanding. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five Business Days after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser selected by the Company and the holders of at least 75% of the Outstanding Principal Amount of the Notes then outstanding. The determination of such appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

               (iv) Rounding of Adjustments. All calculations under this Section 3 or Section 1 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.

               (v) Notice of Adjustments. Whenever any Conversion Price is adjusted as provided herein, the Company shall promptly deliver to each holder of the Notes, a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment, provided that any failure to so provide such notice shall not affect the automatic adjustment hereunder.

               (vi) Need for Additional Authorized Shares of Common Stock. The foregoing notwithstanding, in the event the Conversion Price as adjusted as provided herein, giving the Holder the right to acquire more shares of Common Stock than are authorized and reserved for issuance by the Company for such purpose, the Company will promptly convene a meeting of the shareholders and solicit the approval of the shareholders to an increase in the number of shares of authorized Common Stock so as to facilitate conversions at the adjusted Conversion Price.

               (vii) Change in Control Transactions. In case of any Change in Control Transaction, the Holder shall have the right thereafter to, at its option, (A) convert this Note, in whole or in part, at the Conversion Price into the shares of stock and other securities, cash and/or property receivable upon or deemed to be held by holders of Common Stock following such Change in Control Transaction, and the Holder shall be entitled upon such event to receive such amount of securities, cash or property as the shares of the Common Stock of the Company into which this Note could have been converted immediately prior to such Change in Control Transaction would have been entitled if such conversion were permitted, subject to such further applicable adjustments set forth in this Section 3; or (B) require the Company or its successor to redeem this Note, in whole but not in part, at a redemption price equal to 120% of the outstanding Principal Amount being redeemed. The terms of any such Change in Control Transaction shall include such terms so as to continue to give to the Holders the right to receive the amount of securities, cash and/or property upon any conversion or redemption following such Change in Control Transaction to which a holder of the number of shares of Common Stock deliverable upon such conversion would have been entitled in such Change in Control Transaction, and interest payable hereunder shall be in cash or such new securities and/or property, at the Holder’s option. This provision shall similarly apply to successive reclassifications, consolidations, mergers, sales, transfers or share exchanges.

10

               (viii) Notice of Certain Events. If:

then the Company shall cause to be filed at each office or agency maintained for the purpose of conversion of this Note, and shall cause to be mailed to the Holder at its last address as it shall appear upon the books of the Company, on or prior to the date notice to the Company’s stockholders generally is given, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, securities issuance, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange.

          (d) Reservation and Issuance of Underlying Securities. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued Common Stock solely for the purpose of issuance upon conversion of this Note (including repayments in stock), free from preemptive rights or any other actual contingent purchase rights of

11

persons other than the holders of the Notes, not less than such number of shares of Common Stock as shall (subject to any additional requirements of the Company as to reservation of such shares set forth in the Purchase Agreement) be issuable (taking into account the adjustments under this Section 3 but without regard to any ownership limitations contained herein) upon the conversion of this Note hereunder in Common Stock (including repayments in stock). The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid, nonassessable and freely tradeable.

          (e) No Fractions. Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of shares of Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the closing price of a share of Common Stock at such time.

               (i) Conversion Limitations. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the Holder upon conversion pursuant to the terms hereof shall not exceed a number that, when added to the total number of shares of Common Stock deemed beneficially owned by such Holder (other than by virtue of the ownership of securities or rights to acquire securities (including the Notes and Warrants) that have limitations on the Holder’s right to convert, exercise or purchase similar to the limitation set forth herein), together with all shares of Common Stock deemed beneficially owned at such time (other than by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein) by the holder’s “affiliates” at such time (as defined in Rule 144 of the Act) (“Aggregation Parties”) that would be aggregated for purposes of determining whether a group under Section 13(d) of the Securities Exchange Act of 1934 as amended, exists, would exceed 9.9% of the total issued and outstanding shares of the Common Stock (the “Restricted Ownership Percentage”). Each holder shall have the right (w) at any time and from time to time to reduce its Restricted Ownership Percentage immediately upon notice to the Company and (x) (subject to waiver) at any time and from time to time, to increase its Restricted Ownership Percentage immediately in the event of the announcement as pending or planned, of a Change in Control Transaction.

     Section 11. Defaults and Remedies.

          (a) Events of Default. An “Event of Default” is: (i) a default in payment of any amount due hereunder which default continues for more than 5 business days after the due date thereof; (ii) a default in the timely issuance of Underlying Shares upon and in accordance with terms hereof, within ten days following the Conversion Date; (iii) failure by the Company for seven (7) days after written notice has been received by the Company to comply with any material provision of any of the Notes, the Purchase Agreement, the Registration Rights Agreement or the Warrants (including without limitation the failure to issue the requisite number of shares of Common Stock upon conversion hereof and the failure to redeem Notes upon the Holder’s request following a Change in Control Transaction pursuant to Section 4(f); (iv) a material breach by the Company of its covenants, representations or warranties in the Purchase Agreement, Registration Rights Agreement or Warrants; (v) if the Company is subject to any Bankruptcy Event; or (vi) a violation of section 2 hereof.

          (b) Remedies. If an Event of Default occurs and is continuing with respect to any of the Notes, the Holder may declare all of the then outstanding Principal Amount of this Note and all other Notes held by the Holder, including any interest due thereon, to be due and payable immediately, except that in the case of an Event of Default arising from events described in clause (v) of Section 11(a), this Note shall become due and payable without further action or notice. In the event of such acceleration, the amount due and owing to the Holder shall be 120% of the outstanding Principal Amount of the Notes held by the Holder (plus all accrued and unpaid interest, if any). The Company shall pay interest on such amount in cash at the Default Rate to the Holder if such amount is not paid within 7 days of Holder’s request. The remedies under this Note shall be cumulative.

          (b) Savings Clause. In case any provision of this Note is held by a court of competent jurisdiction to be excessive in scope or otherwise invalid or unenforceable, such provision shall be adjusted rather than voided, if possible, so that it is enforceable to the maximum extent possible, and the validity and enforceability of the remaining provisions of this Note will not in any way be affected or impaired thereby. In no event shall the amount of interest paid hereunder exceed the maximum rate of interest on the unpaid principal balance hereof allowable by applicable law. If any sum is collected in excess of the applicable maximum rate, the excess collected shall be applied to reduce the principal debt. If the interest actually collected hereunder is still in excess of the applicable maximum rate, the interest rate shall be reduced so as not to exceed the maximum allowable under law.

          (e) No Waiver. No failure on the part of the Holder to exercise, and no delay in exercising any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by the Holder of any right, remedy or power hereunder preclude any other or future exercise of any other right, remedy or power. Each and every right, remedy or power hereby granted to the Holder or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by the Holder from time to time.
