          more of the total number of hearing aids purchased by the Borrower,
          net of returns (such cumulative amount determined as a percentage, the

          Quarterly Payment Date, eighty percent (80%) or more of the total
          number of hearing aids purchased by the Borrower but less than ninety

          Tranche C Quarterly Payment; and

               (iii) if the Borrower has not purchased pursuant to the Supply

          2.03(c)(i).

          Payment Date;

               (ii) if the Borrower has purchased pursuant to the Supply

          Required Tranche B Payment times (ii) (A) 100% minus (B) the
          difference of (1) the Minimum Purchase Percentage and (2) the
          cumulative percentage of purchases of hearing aid products made by

          By way of example, if Borrower purchased 80% of its cumulative second
          Fiscal Quarter requirements from Lender during any such period, then
          Borrower will be deemed to have made a payment for the applicable Loan
          Payment Date equal to 90% of such Required Tranche B Payment on the
          applicable Tranche B Loan Payment Date; and

and equal to $6,576,391. The remainder of the Tranche C Loan made on the Closing
Date shall accrue interest at a rate per annum equal at all times to the Prime
Rate plus 1.0% and shall be payable on the 20th day after the end of each Fiscal
Quarter, subject to the deemed payments credits as contemplated by Section
2.03(d). With respect to each Tranche C Loan made after the Closing Date,
Borrower agrees that such Loans shall accrue interest at a rate per annum equal
at all times to the Prime Rate plus 1.0% from the date deemed made until the
principal amount thereof shall be paid in full; however, such accrued interest
shall not be added to accrued interest which is paid as part of the current
interest in a Required Quarterly Tranche C Payment, but shall accrue and be
added to the principal amount of Tranche C (i.e., compounded) on each Tranche C
Quarterly Payment Date until paid in full. Each Tranche C Loan made after the
Closing Date shall be deemed to be made on the first day of the Fiscal Quarter
in which such Tranche C Loan is made.

     Section 2.07. Illegality.

          Notwithstanding any other provision of this Agreement, if the
introduction of or any change in or in the interpretation of any law or
regulation shall make it unlawful, or any central bank or other Governmental
Authority shall assert that it is unlawful, for the Lender to make or continue
the Loans, then, on notice thereof and demand therefor by the Lender to the
Borrower, (a) the obligation of the Lender to make or to continue the Loans
shall terminate and (b) the Borrower shall forthwith prepay in full the Loans
then outstanding, together with interest accrued thereon.

     Section 2.08. Payments and Computations.

          (a) The Borrower shall make each payment hereunder and under the Notes
not later than 11:00 A.M. (New York City time) on the day when due, in Dollars,
to the Lender at its address referred to in Section 8.02 in immediately
available funds without set-off or counterclaim. Payment received by the Lender
after 1:00 PM (New York City time) shall be deemed to be received on the next
Business Day.

          (b) The Borrower hereby authorizes the Lender, if and to the extent
payment owed to the Lender is not made when due hereunder, to charge from time
to time against any or all of the Borrower's accounts with the Lender any amount
so due.

          (c) All computations of interest hereunder shall be made by the Lender
on the basis of a year of 365/6 days and number of days elapsed.

          (d) Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest.

     Section 2.09. Taxes.

          (a) Any and all payments by the Borrower under each Loan Document
shall be made free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of the Lender taxes
measured by its net income, and franchise taxes imposed on it, by the
jurisdiction of the Lender's applicable lending office or any political
subdivision thereof (all such non-excluded taxes, levies, imposts, deductions,
charges, withholdings and liabilities being hereinafter referred to as "Taxes").
If the Borrower shall be required by law to deduct any Taxes from or in respect
of any sum payable hereunder to the Lender (i) the sum payable shall be
increased as may be necessary so that after making all required deductions
(including, without limitation, deductions applicable to additional sums payable
under this Section 2.09) the Lender receives an amount equal to the sum it would
have received had no such deductions been made, (ii) the Borrower shall make
such deductions and (iii) the Borrower shall pay the full amount deducted to the
relevant taxing authority or other authority in accordance with applicable law.


                                       17

          (b) In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies of the United States or any political subdivision thereof or any
applicable foreign jurisdiction which arise from any payment made under any Loan
Document or from the execution, delivery or registration of, or otherwise with
respect to, any Loan Document (collectively, "Other Taxes").

          (c) The Borrower will indemnify the Lender for the full amount of
Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 2.09) paid by
the Lender and any liability (including, without limitation, for penalties,
interest and expenses) arising therefrom or with respect thereto. This
indemnification shall be made within 30 days from the date the Lender makes
written demand therefor, accompanied by reasonable supporting documentation and
calculations.

          (d) Within 30 days after the date of any payment of Taxes or Other
Taxes, the Borrower will furnish to the Lender, at its address referred to in
Section 8.02, the original or a certified copy of a receipt evidencing payment
thereof.

          (e) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.09 shall survive the payment in full of the other Obligations.
Lender agrees that, as promptly as practicable after the officer of Lender
responsible for administering its Loans becomes aware of the occurrence of an
event or the existence of a condition that would entitle Lender to receive
payments under this Section 2.09, it will, to the extent not inconsistent with
the internal policies of such Lender and any applicable legal or regulatory
restrictions, use reasonable efforts to (a) make, issue, fund or maintain its
applicable Commitments or Loans through another office of Lender, or (b) take
such other measures as Lender may deem reasonable, if as a result thereof the
circumstances which would cause the additional amounts which would otherwise be
required to be paid to Lender pursuant to this Section 2.09 would be reduced and
if, as determined by Lender in its reasonable discretion, the making, issuing,
funding or maintaining of such Commitments or Loans through such other office or
in accordance with such other measures, as the case may be, would not otherwise
adversely affect such Commitments or Loans or the interests of Lender.

          (b) The Borrower agrees to indemnify and hold harmless the Lender and
its Affiliates, and the directors, officers, employees, agents, attorneys,
consultants and advisors of or to any of the foregoing (each of the foregoing
being an "Indemnitee") from and against any and all claims, damages,
liabilities, obligations, losses, penalties, actions, judgments, suits, costs,
disbursements and expenses of any kind or nature (including, without limitation,
fees and disbursements of counsel to any such Indemnitee) which may be imposed
on, incurred by or asserted against any such Indemnitee in connection with or
arising out of any investigation, litigation or proceeding, whether or not any
such Indemnitee is a party thereto, whether direct, indirect, or consequential
and whether based on any federal, state or local law or other statutory
regulation, securities or commercial law or regulation, or under common law or
in equity, or on contract, tort or otherwise, in any manner relating to or
arising out of this Agreement, any other Loan Document, any Obligation, or any
act, event or transaction related or attendant to any thereof, (collectively,
the "Indemnified Matters"); provided, however, that the Borrower shall not have
any obligation under this Section 8.04(b) to an Indemnitee with respect to any
Indemnified Matter caused by or resulting from the gross negligence or willful
misconduct of that Indemnitee.

          (c) The Borrower, at the request of any Indemnitee, shall have the
obligation to defend against such investigation, litigation or proceeding, and
the Borrower, in any event, may participate in the defense thereof with legal
counsel of the Borrower's choice. In the event that such Indemnitee requests the
Borrower to defend against such investigation, litigation or proceeding, the
Borrower shall promptly do so, and such Indemnitee shall have the right to have
legal counsel of its choice participate in such defense, and all costs and
expenses of such counsel shall be borne by the Borrower. No action taken by
legal counsel chosen by such Indemnitee in defending against any such
investigation, litigation or proceeding, shall vitiate or in any way impair the
Borrower's obligation and duty hereunder to indemnify and hold harmless such
Indemnitee.

          (d) The Borrower agrees that any indemnification or other protection
provided to any Indemnitee pursuant to this Agreement (including, without
limitation, pursuant to this Section 8.04) or any other Loan Document shall (i)
survive payment of the Obligations and (ii) inure to the benefit of any Person
who was at any time an Indemnitee under this Agreement or any other Loan
Document.

     Section 8.05. Right of Set-off.

          Upon the occurrence and during the continuance of any Event of Default
the Lender is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by the Lender to or for the credit or the
account of the Borrower against any and all of the Obligations now or hereafter
existing whether or not the Lender shall have made any demand under this
Agreement, the Notes or any other Loan Document and although such Obligations
may be unmatured. The Lender agrees promptly to notify the Borrower after any
such set-off and application made by the Lender; provided, however, that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of the Lender under this Section are in addition to the
other rights and remedies (including, without limitation, other rights of
set-off) which the Lender may have.
