The parties recognize that the transaction will require further documentation and approvals, including the preparation and approval of a formal agreement setting forth the terms and conditions of the proposed purchase ("Asset Purchase Agreement"); nevertheless, they execute this letter to evidence their intention to proceed in mutual good faith to complete work required to negotiate terms of an Asset Purchase Agreement that are consistent with this letter. 2 The proposed terms and conditions include, but are not limited to, the following: PURCHASE OF ASSETS: The Buyer will purchase the Assets from the Corporation.

Notwithstanding the foregoing Buyer shall be free to sell Products bearing the trademark "3M" following the License Termination Date if such product was in inventory as of the Closing or returned to inventory as a result of a return for reimbursement or credit in accordance with customary practice. Buyer is hereby licensed for a period of five years following the Closing to reference 3M, subject to 3M's prior written approval of said reference, which approval shall not unreasonable be withheld, as one of the sources of the technology used in any ReSound product so long as such product embodies the technology included in one of the patents included among the Assets. 3 4 b.

Buyer agrees to recognize all years of employment with Corporation as years of service with Buyer for the purpose of computing years of service for benefits plan purposes for all of Corporation's employees who become employees of Buyer at and as a result of the Closing. 4 5 e. Corporation shall provide the Business, at no charge, information systems access, information services, accounting, billing, and cost reports services for thirty days following Closing.

Corporation shall be liable for excessive and obsolete inventory determined following an evaluation conducted by Buyer's independent auditors prior to Closing. j. In the event Buyer cannot or elects not to assume certain agreements related to the Business, then Buyer and Corporation will work together in a mutually acceptable arrangement in order for Corporation to fulfill its obligations under said agreements. Buyer shall receive a non-exclusive license to the CID Patents included among the Assets. Corporation shall not grant another non-exclusive license for such patents without Buyer's permission. Corporation will use its best efforts to assist Buyer to negotiate a direct contractual relationship with the owner of the CID Patents and will, if requested by Buyer, assign to Buyer all rights under its license agreement concerning the CID Patents or relinquish all its rights under such agreement. k. Corporation shall grant Buyer a royalty free license for any patent used in the Business but not part of the Assets. ACCESS: To permit Buyer to conduct its due diligence investigation, from March 20, 1996 and as long as this Letter of Intent remains in effect, the Corporation will permit the Buyer and its agents to have reasonable access to the premises in which the Corporation conducts the Business and to its books and records and will furnish to Buyer such financial data, operating data, and other information as Buyer shall reasonably request. The Buyer agrees to retain all information so obtained from Corporation on a confidential basis. Upon the termination of this Letter of Intent for 6 7 any reason, the Buyer shall return promptly to the Corporation all printed information received by the Buyer from the Corporation in connection with the proposed transaction. ORDINARY COURSE OF BUSINESS: The parties agree that the Business will be operated from the date hereof through the Closing in the ordinary course of its business, consistent with past practices. Without limiting the foregoing, there shall be no change in accounting policies applied on a consistent basis and no accruals for payment of investment bankers or counsel fees with respect to the transaction for the Buyer or the Corporation. There shall not be any change in or restrictions placed on the payment of liabilities pending the Closing. There shall not be any change in the method by which bonuses or other payments are made to employees of the Business. EXCLUSIVITY: The parties agree to negotiate in good faith the provisions of an Asset Purchase Agreement not later than June 15, 1996 ("Exclusivity Period"). The parties agree that during the Exclusivity Period the Buyer shall have the exclusive right to negotiate with the Corporation for the purchase of the Assets and during such Exclusivity Period the Corporation agrees not to directly or through intermediaries solicit, entertain or otherwise discuss with any person any offers to purchase all or any portion of the Assets or of the Business out of its ordinary course of business. 7 8 EARNEST PAYMENT: Buyer and Corporation recognize that Corporation has provided to Buyer valuable competitive and proprietary information regarding the Business including but not limited to information regarding the Business' customers, products, manufacturing operations and personnel. Buyer and Corporation each further recognize that in the event the aforementioned transaction is not consummated, then Corporation's Business will be irreparably damaged and harmed. Accordingly, Buyer agrees that the first One Million Dollars ($1,000,000) of the Purchase Price referred to above shall constitute an earnest payment (the "Earnest Payment") to be deposited immediately upon payment in an interest bearing account at a reputable institution acceptable to both Buyer and Corporation with all interest accrued on such amount prior to the Closing or the date the parties reasonably conclude that the transaction contemplated hereby will not occur ("the Termination Date"), whichever occurs first, to be paid to Buyer. In the event the transaction is not consummated due to (i) the failure to obtain the receipt of all required approvals, consents and authorizations of state and federal regulatory authorities, including but not limited to expiration without regulatory challenge of the required waiting period under the Hart-Scott-Rodino Improvements Act of 1986; (ii) a material change in sales revenue or costs defined as a 20% deviation of the Business; or (iii) failure to obtain Corporation's management committees' approval and Corporation's Board of Directors' approval, then the Earnest Payment shall be returned to Buyer, otherwise, Corporation retains the right to the Earnest Payment and all 8 9 interest earned thereon from and after the Termination Date. In the event the transaction is consummated, then the Earnest Payment shall constitute the first $1 million of the Purchase Price. COVENANT NOT TO COMPETE: In the Asset Purchase Agreement, Corporation will agree that it will not, directly or indirectly, through a subsidiary or otherwise, compete with the Buyer in its business for a period of five (5) years after the Closing. NEWS RELEASE: Unless required in the opinion of Counsel, neither Corporation nor Buyer will issue a news release or other announcement concerning the transaction without the prior approval of the other as to the contents of the announcement and its release, which approval will not be unreasonably withheld. REIMBURSEMENT OF EXPENSES: Each party shall bear its own cost involved in the negotiation, documentation and conclusion of the transaction contemplated herein. Buyer will pay the filing fee associated with the Hart-Scott- Rodino Improvements Act of 1986. This offer is contingent upon: (i) the completion by the Buyer, to its satisfaction, of due diligence on the Business, its markets, prospects and potential; (ii) satisfactory completion of legal due diligence, including, without limitation, review of material 9 10 contracts and due diligence with respect to evaluation of potential liabilities related to environmental and other issues and tax matters; (iii) receipt of all required approvals, consents and authorizations of state and federal regulatory authorities, including but not limited to expiration without regulatory challenge of the required waiting period under the Hart-Scott-Rodino Improvements Act of 1986; (iv) receipt of all required consents of third parties; (v) the occurrence of no material adverse change in sales revenue or cost, as defined as 20% deviation from forecasts made available to Buyer prior to the date of this letter; and (vi) the completion of satisfactory legal documentation including adequate indemnifications and representations; (vi) Buyer obtaining adequate financing for the Purchase Price on or prior to the Closing; (vii) approved by appropriate management committees and Boards of Directors of Buyer and Corporation. The parties agree that any discussions or information in any form related to the possible terms of the transaction (including but not limited to valuations of any of the Assets by either party as part of the negotiations) have been disclosed in part in contemplation of settlement of the pending patent litigation involving the parties and shall be inadmissible as evidence in any patent litigation between the partners should the transaction contemplated hereby not take place. This Letter of Intent may be executed in several counterparts and all so executed shall constitute one letter binding on all the parties hereto even though all the parties are not signatories to the original or the same counterpart. Our signature on this Letter of Intent shall not be valid unless you have executed and we have received from you a copy of this Letter of Intent with your original signature on it.
