The undersigned Registrant hereby amends and restates its Current Report on Form 8-K filed with the Securities and Exchange Commission on July 20, 2000, which excluded certain financial statements and pro forma financial information not available at the time of filing. Item 2. Acquisition or Disposition of Assets. On July 5, 2000, pursuant to the "Asset Purchase Agreement" dated July 5, 2000, Gentner Communications Corporation, (the "Registrant"), purchased substantially all of the assets of ClearOne, Inc. (Woburn, Mass.), a privately-held developer and manufacturer of multi-media group communications products. The Registrant will account for the acquisition of these assets under the purchase method of accounting. The assets were acquired with $1.76 million in cash and 129,871 shares of the Registrant's restricted stock. The cash purchase price was paid from the Registrant's general working capital. The total value of consideration paid for the assets was determined based on arm's length negotiations between the Registrant and ClearOne, which took into account ClearOne's financial position, operating history, products, intellectual property and other factors relating to ClearOne's business. There are no material relationships between ClearOne and the Registrant prior to completion of this transaction. The assets purchased were used in the development and support of ClearOne's component technology products for both audio and video teleconferencing applications. The Registrant currently intends to use such assets in substantially the same manner. The Registrant will retain ClearOne's facilities in Woburn, MA. Item 7.

EDWARD A. SCRIBNER, CPA 170 WORCESTER STREET, SUITE 208 WELLESLEY, MA 02481-5508 INDEPENDENT AUDITOR'S REPORT To the Board of Directors and Stockholders of ClearOne, Inc. I have audited the accompanying balance sheet of ClearOne, Inc. a Massachusetts corporation as of April 30, 2000, and the related statements of operations, changes in stockholders' equity and cash flows for the year then ended. These financial statements are the responsibility of the Company's management. My responsibility is to express an opinion on these financial statements based on my audit. I conducted my audit in accordance with generally accepted auditing standards. Those standards require that I plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. I believe that my audit provides a reasonable basis for my opinion. In my opinion, the financial statements referred to above present fairly, in all material respects, the financial position of ClearOne, Inc. as of April 30, 2000, and the results of its operations and its cash flows for the year then ended in conformity with generally accepted accounting principles.

ClearOne, Inc. Notes To Financial Statements April 30, 2000 Note 1. - Summary of Significant Accounting Policies The Company ClearOne, Inc. (the Company) was a development stage enterprise, up through April 30, 1999. The Company has undertaken the development and marketing of new technologies in the field of audio conferencing. The financial statements and notes are representations of the Company's management, who is responsible for their integrity and objectivity. The accounting policies of the Company are in accordance with generally accepted accounting principles and have been consistently applied in preparing these financial statements. The Company initially incorporated in New Jersey. The Company's founders and attorney shortly thereafter decided it would be better to conduct business under Massachusetts law. The Company transferred its stock subscriptions and related deposits for stock to a Massachusetts corporation as of May 6, 1997, the date of incorporation in Massachusetts. The Company was originally incorporated under the name, InterVision Corporation, Inc., and then changed its name to ClearOne, Inc. The Company designs, markets, and manufactures high performance telecommunications equipment. ClearOne, Inc. is a privately held company located in Woburn, Massachusetts. Use of Estimates The preparation of the financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that effect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Revenue Recognition Revenues from product sales are recognized when earned. For financial reporting purposes, revenues generated by sales to distributors and retailers under agreements allowing certain rights of return may be deferred until the product is sold by the distributor or retailer. Revenues from licensing of products will be recognized upon contract execution, provided all shipment and significant obligations have been met, fees are fixed or determinable and collection is probable. Revenue, if any, from maintenance contracts and upgrade agreements will be recognized ratably over the contract and upgrade agreement. Revenue, if any, from consulting and training is recognized upon performance. Cash, Cash Equivalents, and Short Term Investments The Company considers all highly liquid debt instruments with an original maturity of three months or less to be cash equivalents. Management determines F-7

the appropriate classification of debt and equity securities at the time of purchase and reevaluates the classification at each reporting date. During the year ended April 30,2000, the Company classified its investments as available-for-sale. The cost of the Company's investments is determined based upon specific identification. Investments classified as available-for-sale are reported at fair value with unrealized gains and losses, net of related tax, if any, recorded as a separate component of stockholder's equity. At April 30, 2000, the Company's investments classified as available-for-sale totaled zero. Cash equivalents include a $60,000 good faith deposit returnable on demand by Company from a foreign contract manufacturer. The deposit is presented at cost and has subsequently been returned to Company on June 30, 2000. Inventory Inventory is stated at the lower of cost using the first-in, first-out method, or market, defined as net realizable value. At April 30, 2000 inventory consists of raw materials of $485,499 and finished goods of $164,852 valued at net realizable value. The amount reported as inventory at April 30, 2000 is after a write down of $91,180 to reflect market value as net realizable value. The amount was charged to other income and expenses since the Company entered into a sale of the bulk of its inventory on July 5, 2000, at a price that is deemed to be the net realizable value. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method based upon the shorter of the estimated useful lives, ranging from three to five years or the lease term of the respective assets as follows: Furniture and fixtures 5 years, Computer and testing equipment 3 years, and leasehold improvements 5 years. Molds and dies have been developed for products, and their cost of $156,303 is included in equipment. The cost has not been depreciated due to the fact that the molds and dies have not been placed into service since use has not been considered significant. Leasehold improvements totaling $20,446 (original cost) abandoned at prior locations have been written off during the year ended April 30, 2000. Developed Software and Product Design Research and development costs are charged to operations as incurred. In accordance with FAS-86, costs incurred to develop software that will be sold, leased, or otherwise marketed by the Company are capitalized after technological feasibility has been established and through the period of general availability of the product. During the year ended April 30, 2000, the Company had none. License Agreements The Company has purchased certain software licensing agreements for software and module components to be included in their products. Management has capitalized the license agreements and amortizes them over the useful lives of 5 years. Amortization of license agreements for the year ended April 30, 2000 equaled $52,250. The carrying value of the long term assets such as license agreements that are granted to the company are reviewed on an annual basis for the existence of facts or circumstances both internally and externally that may suggest impairment. The Company determined as of April 30, 2000, that an impairment had occurred based on gross expected future cash flows being insignificant, if any, since the license agreements significantly pertain to a suspended product. The cash flow estimates used to determine the impairment contain management's best estimate using appropriate and customary assumptions and projections as of April 30, 2000. The amount of the impairment was $156,751. F-8

On March 24, 1999, the Company granted a perpetual, worldwide, irrevocable, non-exclusive and non-transferable license to VideoServer, Inc., now called Ezenia, Inc., for certain software in source and object code form, and reference hardware design, except as part of a sale of the portion of the Company's business associated with software or reference design, or a merger or sale of all the stock or assets of either the Company or VideoServer, without the prior consent of the other party. The license is to use and modify software and the reference design, in all forms, including but not limited to source code and object code forms. Ezenia, Inc. and its subsidiaries may use the software and the reference design for the purpose of creating conferencing products as well as making, using, selling and licensing such products. Ezenia, Inc. must restrict access to employees, consultants and contractors who need to know. Ezenia's products may be demonstrated, loaned, marketed, sold and or sub-licensed without restriction either or through its channels of distribution. The Company further grants to Ezenia, Inc. a perpetual, worldwide, irrevocable, non-exclusive, non-transferable right and license to use the software internally and to sub-license (under legally enforceable agreements) and distribute the software in object code form, to end users and/or resellers, as part of or in conjunction with the Ezenia products except as part of a sale of the portion of the Company's business associated with the software or reference design or a merger or sale of substantially all of the stock or assets of either the company or Ezenia without the prior consent of the other party which consent shall not be unreasonable withheld. Ezenia may also sub-license the source code to the software provided it is in conjunction with or as part of the Ezenia products (hardware and software) and where in circumstances Ezenia must place source code into escrow as part of a maintenance or support agreement. Ezenia, Inc. will be entitled to a finder's fee of 6% from any referrals that obtain rights to the reference design or software for the purpose of creating a product from the company as a result of a demonstration of the product. In consideration of the license rights granted by the company to Ezenia, Ezenia paid a license fee of $400,000 that was reflected as unearned license revenue as of April 30, 1999 until shipment and obligations had been met. On August 5, 1999, the Company had fulfilled its shipment and other contractual obligations; the Company was able to reflect the $400,00 as license revenue. Ezenia will also pay $4,000 for each hardware unit ordered, After 180 days of free software upgrade, the Company will receive $25,000 per year for any and all updates purchased by Ezenia. As of April 30, 2000, The Company had received zero dollars under this agreement. The Company agrees to indemnify, defend and hold Ezenia harmless from and against any claims, actions, or demands alleging that the software in its unmodified form directly infringes or misappropriates any U.S. patent, trademark, copyright, trade secret and proprietary right of any third party. Breach of contract for any cause or action under this agreement, will be solely limited to the actual dollar amount that either party received from the other as a result of this agreement. Intangible Assets Intangible assets consist of pending trademarks and patents. The costs incurred have been capitalized and will be amortized over the useful life of the trademarks and patents once they have been approved. Management has deemed that the pending trademarks have no future use due to the sale of some of the Company's assets as described in Note 12. The cost of $5,884 for pending trademarks has been written off as a charge to loss on asset dispositions during the year ended April 30, 2000. Income Taxes The principal items accounting for the differences between the income tax benefits computed using the United States statutory rate and the provision for income taxes are as follows: F-9

April 30, 2000 Federal tax benefit at statutory rate $ (442,615) State tax benefit, net of federal effect (123,672) Research and experimentation credits ( -- ) Unutilized net operating losses 566,287 ------- Total $ -- Net deferred tax assets comprise: Net operating loss carry forwards $ 2,677,112 Research and experimentation credit carry forwards 175,408 Valuation allowance (2,852,520) ----------- Net deferred tax assets $ -- Due to the uncertainty surrounding the realization of the deferred tax assets in the future tax returns, the Company has placed a valuation allowance against its otherwise recognizable net deferred tax assets. Should the Company achieve profitability, these deferred tax assets may be available to offset future income tax liabilities and expenses. At April 30, 2000 the Company had the following carry forwards available to reduce future taxable income and income taxes: Federal State Net operating loss carry forwards $ 6,154,281 $ 6,152,913 Research and experimentation credit carry forwards $ 124,240 $ 51,168 The federal and state net operating loss carry forwards expire through the year 2020, and the research and experimentation credit carry forwards expire through the year 2019. For federal and state tax purposes, the Company's net operating loss and research and experimentation credit carry forwards could be subject to certain limitations on annual utilization if certain changes in ownership were to occur, as defined by federal and state tax laws. The Company has a current tax liability to the State of Massachusetts payable in the amount of $456 due to the jurisdiction's minimum excise tax. Concentration of Credit Risk and Uncertainties Financial instruments that potentially subject the Company to significant concentrations of risk consist principally of cash, cash equivalents, short-term investments and trade accounts receivable. The Company places its cash, cash equivalents, and short-term investments in market rate accounts with reputable financial institutions. At times, such deposits in the United States may be in excess of FDIC insured limits. Cash equivalents may present risk of changes in value because of interest rate changes. The trade accounts receivable risk is limited due to the breath of entities comprising the Company's direct customer base and that of its distributors and also their dispersion across different industries and geographical regions. The Company evaluates the credit worthiness of customers, as appropriate and maintains an adequate allowance for potential uncollectible accounts. F-10

The Company has entered into numerous distribution agreements both domestically and internationally in order to obtain distribution channels for its products. These agreements generally provide lower and favorable pricing arrangements in comparison to a direct or retail sale. These agreements provide the distributors in some cases, advertising allowances, volume discounts, payment discounts, pricing protection for a limited amount of time in most cases 60 days notice and standard warranty guarantee, one year domestically and in some cases eighteen months internationally. Some of the agreements require minimum annual sales to maintain favorable pricing terms. All agreements are subject to annual review and contain release clauses for non-performance without penalty for early terminations. The Company has entered into an international distribution agreement that calls for all payments to be made by the distributor in the currency of the New Taiwan dollar. As of April 30, 2000, there is immaterial exposure associated with this agreement. Fair Value of Financial Instruments The carrying amount for the Company's financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the general immediate or short term maturity of these financial instruments. Accounting For Stock-Based Compensation Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation", encourages but does not require, companies to record compensation cost for stock-based employee compensation plans at fair value. The Company has chosen to continue to account for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. Accordingly, the compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company's stock at the date of the grant over the amount an employee or consultant must pay to acquire the stock. As of April 30, 2000, there has been no compensation expense recognized because the grant price exceeds the market price. Advertising Advertising costs amounting to $113,577 for the year ended April 30, 2000 were charged to marketing and selling as incurred. The Company has entered into a co-marketing agreement with a publicly traded company to cooperate in the development of teleconferencing solutions through joint use of both companies' products. This agreement was for one year, beginning April 23, 1998 and ending on April 23, 1999, with terms for an automatic annual renewal. Both companies agreed to create joint marketing resources to market their bundled products. These efforts include, but are not limited to: joint training sessions, application notes, demonstration programs, road-show promotions, trade show exhibits, advertising, trade journal articles, and demonstration units. This agreement has been terminated as of July 5, 2000. F-11

Warranty Cost and Reserve The Company generally provides a warranty for up to one year on domestic sales and eighteen months for international sales at no extra charge. A reserve is recorded for probable costs in connection with warranties based on Company's experience. The accrued warranty costs were $3,949 for the year ended April 30, 2000. Warranty cost directly charged to cost of goods sold were $6,677 for the year ended April 30, 2000. Commissions Effective October 1, 1999, the Company entered into a Full Service Representative Agreement with USA Marketing Group, Inc. in which the Representative would be its exclusive sales representative to solicit orders on all of the Company's product in the Continental United States, for 5% of net invoice price of products. The original agreement was effective October 1, 1999 with either party able to cancel the agreement by giving 60 days advance notice to the other party. On January 22, 2000, the Company and the Representative amended the agreement so that the Representative starting March 1, 2000 would be paid a monthly consulting fee of $2,500 for the period March 1, 2000 through June 1, 2000 and an advance commission of $2,500 a month from the period March 1, 2000 through June 1, 2000. The Company will deduct the advance commission from the monthly commission due. During the year ended April 30, 2000, all fees paid to the Representative for $10,598 have been expensed to marketing and selling. As of June 1, 2000 either party can again cancel the agreement by giving 60 days advance notice to the other party. As of June 30, 2000, the Company verbally notified Representative that the agreement was terminated. Note 2. - Revolving Line of Credit At April 30, 2000, the Company has a $3,500,000 revolving line of credit with a stockholder of which $2,892,000 was outstanding and payable to the stockholder. Available credit at April 30, 2000 was $608,000. The agreement is collateratized by inventory, chattel paper, equipment, general intangibles and fixtures and insurance proceeds associated with these described items. All rents, monies, payments, other rights arising out of a sale, lease or other disposition of any of the property described above is considered substitute collateral. Starting October 1, 1999, all interest due on the outstanding line of credit was paid and further interest is to be calculated monthly on the outstanding line as of the first day of the month. The revolving line of credit bears a fixed interest rate at 8.5%. The Company may borrow against the line of credit until the stockholder makes demand. At that time, the full amount of the revolving line of credit will be due and payable. The revolving line of credit contains certain financial covenants including events of default which allow the stockholder other collateral including the right of set off against checking, savings and other investment accounts of the corporation, continuing security agreements which remain in effect even though all or any part of the indebtedness is paid in full and even though for a period of time the corporation may not be indebted to stockholder; the Company cannot bulk sale assets, transfer assets, assign collateral or borrow without prior written consent of stockholder which consent would not be unreasonably withheld.

Stock Warrants Warrants to purchase 2,000,000 shares of the Company's common stock at a price per share of $2 have been granted to the Company's first round investors exercisable on or before any initial public offering date, which is yet to be determined. Note 5. - Stock Option Plans In 1997, the Company completed its initial private offering (the offering) of its common stock selling 2,000,000 shares at $2 per share. In 1997, the Company established a stock option plan which is currently being treated as a non-qualified stock option plan. The Company has set aside 2,715,000 shares of its common stock for this plan. A certain percentage of the shares granted will be vested after one year with the remaining shares under the stock option plan vesting at 6.25% quarterly thereafter until fully vested. Another portion of the original award under the stock option plan would be F-13

granted after one year and based on the holder's performance as reviewed by his/her immediate supervisor and then the compensation committee. The final portion of the award under the stock option plan will be granted after two years and will be based on the Company's performance as determined by its annual audited financial statements. Vesting is strictly conditional on the employee remaining a full-time employee. If an individual ceases to be an employee of the company he has 90 days to exercise any vested options that they may have had. As of April 30, 2000, no one who has left the company has exercised any stock options. Further restrictions may apply as detailed in the Company's stock option plan. The option price is determined by the compensation committee based on the Company's current financial status. In addition, the Company has set aside 85,000 shares of its common stock for consultants who perform key services to the Company. The option price is determined by the compensation committee based on the Company's current financial status. Vesting is determined on a case-by-case basis by the compensation committee Note 6. - Recapitalization and Capital Structure On January 12, 1999, the Company undertook a recapitalization of its capital structure by unanimous consent of the stockholders. The authorized capital stock of the Company was changed from 10,000,000 shares of common stock, $.01 par value to the following: 11,000,000 shares common stock, $.01 par value; 2,000,000 shares Series B preferred stock, $.01 par value; and 1,000,000 shares Series A preferred stock, $.01 par value. The founders retained their class of shares as Common Stock for a total of 3,200,000 shares, $.01 par value. The first round investors converted their total of 2,000,000 shares of Common Stock in a one for one conversion to Series B Preferred Stock retaining the same par value and paid-in capital value. Series A Preferred Stock was issued in the year ended April 30, 1999 as a second round of equity financing. Common Stock: The voting, dividend, and liquidation rights of the holders of Common Stock are subject to and qualified by the rights of the holders of the Series B and Series A Preferred Stock. The holders of the Common Stock are entitled to one vote for each share held at all meetings of stockholders (and written actions in lieu of meetings). Dividends may be declared and paid on the Common Stock from funds lawfully available therefore as and when determined by the Board of Directors and subject to any preferential dividend rights of any then outstanding Series B or Series A Preferred Stock. Upon the dissolution or liquidation of the Company, whether voluntary or involuntary, holders of Common Stock will be entitled to receive all assets of the Company available for dissolution to its stockholders, after paying revolving line of credit and subject to any preferential rights of any then outstanding Series B or Series A Preferred Stock. Series B Preferred Stock: Scheduled to start on January 1, 2000, the holders of the Series B Preferred Stock will be entitled to receive dividends at the rate of 4% of the sum of $2.00 (the "Original Purchase Price") whenever funds are legal available as and when declared by the Board of Directors. As of the date of these financial statement, no dividends have been declared. Dividends on the Series B Preferred Stock will be non-cumulative. In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series B Preferred Stock will be entitled to receive in preference to the holders of the Common Stock and amount equal to $2.00 per share. Holders of Series B Preferred Stock will have the right to convert their shares of Series B Preferred Stock, at the option of such holder, at any time into shares of Common Stock. The total number of shares of Common Stock into which shares of Series B Preferred Stock may be converted initially will be determined by dividing the Original Purchase Price by the conversion price (the "Conversion Price"). The initial Conversion Price will be the Original Purchase Price. The Conversion Price will be subject to adjustment to reflect stock dividends, stock splits, and similar events on a weighted F-14

average basis to prevent dilution in the event that the Company issues additional shares at a purchase price less than the applicable Conversion Price. The Series B Preferred Stock will be automatically converted into Common Stock, at the then applicable Conversion Price, upon the closing of a sale of the Company's shares of Common Stock pursuant to a firm commitment of underwritten public offering by the Company at a public offering price per share. Except with respect to the election of Directors of the Company, each holder of outstanding shares of Series B Preferred Stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which the shares of Series B Preferred Stock are convertible. As long as there is at least 50% of the Series B Preferred Stock initially issued outstanding, the consent of the holders of at least a majority of the issued and outstanding Series B Preferred Stock voting as a separate class shall be required for (1) changing corporation's articles of organization and/or by-laws which would effect the rights of the Series B Preferred shareholders; (2) creating a new class of stock with a greater preference or priority to Series B as to dividends or assets; (3) creating a convertible bond, notes or other obligations that had a greater preference or priority to Series B as to dividends or assets; (4) a corporate reorganization that would result in common stock having a greater preference or priority to Series B as to dividends or assets; (5) redemption of common stock except from employees, advisors, officers, directors, consultants and service providers which terms have been approved by the Board of Directors; and (6) merger, sale or consolidation of the corporation. Series A Preferred Stock: Scheduled to start on January 1, 2000, the holders of the Series A Preferred Stock will be entitled to receive dividends at the rate of 4% of the sum of $2.60 (the "Original Purchase Price") whenever funds are legal available as and when declared by the Board of Directors. As of the date of these financial statements, no dividends have been declared. No dividend shall be paid on the common stock at a rate greater than the rate at which dividends are paid on the Series B Preferred Stock. Dividends on the Series A Preferred Stock will be non-cumulative. In the event of any liquidation, dissolution, or winding up of the Company, the holders of Series A Preferred Stock will be entitled to receive in preference to the holders of the Common Stock and amount equal to $2.60 per share. Holders of Series A Preferred Stock will have the right to convert their shares of Series A Preferred Stock, at the option of such holder, at any time into shares of Common Stock. The total number of shares of Common Stock into which shares of Series A Preferred Stock may be converted initially will be determined by dividing the Original Purchase Price by the conversion price (the "Conversion Price"). The initial Conversion Price will be the Original Purchase Price. The Conversion Price will be subject to adjustment to reflect stock dividends, stock splits, and similar events on a weighted average basis to prevent dilution in the event that the Company issues additional shares at a purchase price less than the applicable Conversion Price. The Series A Preferred Stock will be automatically converted into Common Stock, at the then applicable Conversion Price, upon the closing of a sale of the Company's shares of Common Stock pursuant to a firm commitment of underwritten public offering by the Company at a public offering price per share. Except with respect to the election of Directors of the Company, each holder of outstanding shares of Series A Preferred Stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which the shares of Series A Preferred Stock are convertible. As long as there is at least 50% of the Series A Preferred Stock initially issued outstanding, the consent of the holders of at least a majority of the issued and outstanding Series A Preferred Stock voting as a separate class shall be required for (1) changing corporation's articles of organization and/or by-laws which would effect the rights of the Series A Preferred shareholders; (2) creating a new class of stock with a greater preference or priority to Series A as to dividends or assets; (3) creating a convertible bond, notes or other obligations that had a greater preference or priority to Series A as to dividends or assets; (4) a corporate reorganization that would result in common stock having a greater preference or priority to Series A as to dividends or assets; (5) redemption of common stock except from employees, advisors, officers, directors, consultants and service providers which terms have been approved by the Board of Directors; and (6) merger, sale or consolidation of the corporation.

Note 7. - 401(k) Savings Plan The Company adopted a 401(k) savings plan (the savings plan) covering substantially all of its employees, subject to the age requirement being 21 for participation. Under the savings plan, eligible employees may contribute up to the maximum allowed by the IRS from their compensation to the savings plan. The Company matching contribution is zero at this time. However, the Company has the option to make profit sharing contributions to the plan subject to a predetermined vesting schedule in the future. Note 8. - Going Concern The conditions of recurring operating losses, working capital deficiencies, negative cash flows from operations, seeking new methods of financing, substantial dependency on the success of a particular product, employee turn over, and need to significantly revise operations, indicated that the Company was unable to continue as a going concern for the year ended April 30, 1999. As a result of the subsequent sale of a significant amount of the Company's assets on July 5, 2000, the Company has obtained enough liquidity to continue as a going concern for the immediate future. A stockholder has agreed to fund the financial requirements of the Company if the operating expenses exceed available cash for the foreseeable future. Note 9. - Comprehensive Income In June of 1997, the Financial Accounting Standards Board issued SFAS No.130, "Reporting Comprehensive Income." SFAS No. 130 established standards for reporting comprehensive income and its components in a financial statement. Comprehensive income as defined included all changes in equity (net asset) during a period from non-owner sources. Examples of items to be included in comprehensive income, which are excluded from net income, include foreign currency translation adjustments and unrealized gains/losses on available-for-sale securities. There were no adjustments required for the year ended April 30, 2000. Note 10. - Segment Reporting Effective April 30, 2000, the Company adopted SFAS No.131, "Disclosures About Segments of an Enterprise and Related Information." SFAS No.131 established standards for reporting information by public companies about operating segments in annual financial statements. It also established standards for related disclosure about products and services, geographic areas and major customers. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company's chief operating decision-maker is the chief executive officer of the Company. The Company is predominately a speakerphone manufacturer with its products being distributed and manufactured worldwide for the year ended April 30, 2000. In addition, the Company licenses its technology, and finalized its first license to one customer during the year ended April 30, 2000. Financial information about the segments: Products License Agreement Revenue $ 98,588 $ 400,000 Cost of Goods Sold 77,994 -- F-16

Note 11. - Nonrecurring Charge During the fiscal year ended April 30, 2000. The Company evaluated several aspects of its business and made strategic decisions that effected portions of the Company's business. The Company moved to concentrate its business on its newer speakerphone version and Microphone Pads. This allowed the Company to narrow its focus on key equipment distributors and related products for these distributors. As a result an evaluation and analysis of the Company's license agreements, pending trademarks and certain patents was conducted. Based on the projected earnings and undiscounted cash flow analysis of the affected business activities, the Company determined the fair value of certain assets should be adjusted. Accordingly, certain assets were revalued and $162,635 was recorded as a nonrecurring, non-cash charge. The $162,635 consists of the $156,751 impairment of license agreements, and the $5,884 write down of pending trademarks charged to loss on asset dispositions. The Company does not anticipate any significant cash charge, beyond those recorded, to complete implementation of its new strategic direction. Note 12. - Subsequent Event On or about May 23, 2000 the Company entered into a vendor agreement with a vendor for the period July 7, 2000 through June 30, 2001 which includes a minimum purchase amount by the vendor of $350,000. This order is subject to the terms of the agreement which include, but are not limited to, 120 days price increase notice, guaranteed price decline protection by the Company, the lowest vendor price offered to any other vendor, 9% rebate on the $350,000 gross purchase price, a $5,000 slotting fee per SKU, a 10% gross purchase discount for Market Development Fund and a 1.1% gross dock allowance on receipt of goods from vendor. On July 5, 2000, the Company agreed to sell Gentner Communications Corporation (the Buyer) effectively all of its assets including property and equipment such as but not limited to equipment, furniture and fixtures, leasehold improvements, certain inventories of raw materials and supplies, goods in process and finished goods, intellectual property rights developed and patented, licenses and rights thereunder, remedies against infringements thereof, and rights to participation of enforceable interests therein under the laws of all jurisdictions.

The Buyer shall have the option of recouping all or any adverse consequences as defined in the agreement such as taxes, liens, attorney's fees and damages once the aggregate equals or exceeds $34,000. The Company has ten days to contest claims and subjects offset to arbitration process. F-17

In the event that the Seller disputes a Set-Off Claim, the parties will resolve such dispute using the procedure described in Section 10(p) below, provided that, if the Escrow Period described in this section expires during the existence of a dispute involving a Set-Off Claim, the Escrow Agent shall retain an amount equal to the Set-Off Claim in escrow pending resolution of the dispute, and will release the balance of the Escrowed Amount and Escrowed Shares to Seller. 8.1.7 Notwithstanding anything to the contrary in this Agreement, the Seller shall have no obligation to indemnity the Buyer from and against any Adverse Consequences unless and until the aggregate indemnifiable Adverse Consequences suffered by the Buyer equal or exceed $34,000, net of any proceeds actually received from any insurance policy or policies covering such Adverse Consequences (the "Basket"), at which point the Seller shall be obligated to indemnify the Buyer for all Adverse Consequences (including the Basket). In no event shall the Seller's liability to indemnity the Buyer exceed the Purchase Price. 8.1.8 The foregoing indemnification provisions in this Section 8 are in addition to, and not in derogation of, any statutory, equitable, or common law remedy (including without limitation any such remedy arising under Environmental, Health, and Safety Requirements) any Party may have with respect to the transactions contemplated by this Agreement.

Definitions. As used in this Agreement, the following terms shall have the following meanings: "Asset Purchase Agreement" shall mean the Asset Purchase Agreement between Company and Purchaser dated July 5, 2000.

"Holder" or "Holders" shall mean any Purchaser or any assignee under this Agreement who holds any Registrable Securities (as defined below). The terms "register," "registered" and "registration" refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act (as defined below), including the declaration or ordering of the effectiveness of such registration statement. "Registrable Securities" means the Shares (as defined below) held by Purchasers which have not been registered pursuant to this Agreement. "Registration Expenses" shall mean all expenses incurred by the Company in connection with a registration hereunder, including, without limitation, all registration and filing fees, printing expenses, blue sky fees and expenses, the expense of any special audits incident to or required by any such registration, the fees and disbursements of counsel for the Company. "SEC" shall mean the U.S. Securities and Exchange Commission. "Securities Act" shall mean the Securities Act of 1933, as amended, or any similar federal statute and the rules and regulations of the SEC thereunder.

"Piggy-Back" Registration. ------------------------- (a) If the Company shall determine at any time to register any of its Common Stock or securities which are convertible into or exercisable for Common Stock (other than a registration relating solely to employee benefit plans, a registration relating solely to an SEC Rule 145 transaction, a registration on Form S-4, or a registration on any registration form which does not permit secondary sales or does not include substantially the same information as would be required to be included in a registration statement covering the sale of Registrable Securities), the Company will: (i) promptly give to the Holders written notice thereof (which shall include a list of the jurisdictions in which the Company intends to attempt to qualify such securities under the applicable blue sky or other state securities laws), and (ii) cause to be included in such registration and in any underwriting involved therein all the Registrable Securities specified in a written request or requests made by the Holders within ten (10) days after receipt of such written notice from the Company; provided, however, that the number of Registrable Securities so registered may be limited by the underwriter's cut-back provision set forth in Subsection 2(c) below. (b) If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as part of the written notice given pursuant to Subsection 2(a). In such event, the right of each Holder to register pursuant to Section 2 shall be conditioned upon such Holder's participation in such underwriting and the inclusion of such Holder's Registrable Securities in the underwriting to the extent provided herein. (c) Any Holders proposing to distribute their Registrable Securities through such underwriting shall (together with the Company) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for underwriting by the Company. Notwithstanding any other provision of this Section 2, the Company shall not be required to include in the registration the Registrable Securities of any Holder unless the Holder accepts and agrees to the terms proposed by the underwriters selected by the Company, and then only in such quantity as will not, in the opinion of the underwriters and based on marketing factors identified by such underwriters, jeopardize the success of the offering by the Company. If the total number of Registrable Securities which the Holders request to be included in any offering exceeds the number of Shares which the underwriters reasonably believe is compatible with the success of the offering, then the number of shares to be registered shall be reduced as between the Holders and the Company pro rata based on the ratio of (i) the Registrable Shares to be registered to (ii) all shares of Common Stock of the Company to be registered, provided that the number of shares of Registrable Securities of the Holders to be included shall not be reduced by more than fifty percent (50%) of the total shares that the Holders have requested be included in the registration. E-39

3. Obligations of the Company. Whenever required under Section 2 to effect the registration of any Registrable Securities, the Company shall do the following as expeditiously as possible: (a) Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become and remain effective; provided, however, that, except as set forth in Subsection 3(b) below, the Company shall in no event be obligated to cause such registration statement to remain effective for more than one hundred twenty (120) days. (b) If the registration is effected pursuant to Rule 415 under the Securities Act, which rule allows for the registration of securities to be offered on a continuous or delayed basis, the Company shall promptly (i) take all actions that may be necessary or advisable to maintain the effectiveness of such registration, (ii) at Purchaser's request, file with the SEC a supplement or supplements to the previously filed prospectus as required by Rule 424 under the Securities Act, and (iii) maintain the effectiveness of such registration statement for at least one hundred twenty (120) days following the filing of any such supplements. (c) Prepare and file with the SEC such amendments and supplements to such registration statements and the prospectus used in connection therewith to comply with the requirements of the Securities Act. (d) Furnish to the Holders such number of copies of a prospectus (including a preliminary prospectus), in conformity with the requirements of the Securities Act, and such other documents as such Holders may reasonably request in order to facilitate the disposition of the Registrable Securities to be sold under the registration statement. (e) Use its reasonable best efforts to register and qualify the securities covered by such registration statements under the securities laws of such states of the United States as shall be reasonably appropriate for the distribution of the securities covered by such registration statement. 4. Information by Holder. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Agreement that the Holders of Registrable Securities included in any registration shall cooperate with the Company and any underwriters to effect such registration, including providing to the Company any consents and furnishing to the Company such information regarding such Holders and the distribution proposed by such Holders as the Company may reasonably request in writing and as shall be required in connection with any registration, qualification, or compliance referred to in this Agreement. 5. Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification, or compliance pursuant to Section 2 of this Agreement shall be borne by the Company, and all Selling Expenses shall be borne by the Holders of the securities so registered pro rata on the basis of the number of their Shares so registered. E-40

6. No Delay of Registration. No Holder shall have any right to take any action to restrain, enjoin, or otherwise delay any registration under this Agreement as a result of any controversy that might arise with respect to the interpretation or implementation hereof. 7. Indemnification. In the event that the Registrable Securities of a Holder are included in a registration statement filed under this Agreement: (a) To the extent permitted by law, the Company will indemnify each such Holder, each of its officers, directors and partners, and each person controlling such Holder, with respect to which registration, qualification, or compliance of Registrable Securities of such Holder has been effected pursuant to this Agreement, and each underwriter, if any, and each person who controls any underwriter, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement of a material fact contained in any registration statement, prospectus, offering circular or other document incident to any such registration, qualification, or compliance, or based on any omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or of any rule or regulation promulgated under the Securities Act applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance, and will reimburse each such Holder, each of its officers, directors and partners, each person controlling such Holder, each such underwriter, and each person who controls any such underwriter, for any legal and other expenses reasonably incurred in connection with investigating and defending any such claim, loss, damage, liability, or action; provided that the Company will not be liable in any such case for amounts paid in settlement of any such claim, loss, damage, liability, or action if such settlement is effected without the reasonable consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable to the extent that any such claim, loss, damage, liability, or expense arises out of or is based on any untrue statement or omission in written information furnished to the Company by such Holder with the knowledge that it would be used in the registration statement. (b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which registration, qualification or compliance is being effected, indemnify the Company, each of its directors and officers, each legal counsel and independent accountant of the Company, each underwriter, if any, of the Company's securities covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of the Securities Act, and each other Holder, each of such other Holder's officers, directors, and partners, and each person controlling such other Holder, against all claims, losses, damages, and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular, or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not E-41

misleading, and will reimburse the Company, such other Holders, such directors, officers, partners, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular, or other document in reliance upon and in conformity with written information furnished to the Company by such Holder with the knowledge that it would be used therein, provided that the Holder will not be liable in any case for amounts paid in settlement of any such claim, loss, damage, liability, or action if such settlement is effected without the reasonable consent of the Holder (which consent shall not be unreasonably withheld). (c) Each party entitled to indemnification under this Section (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein, if substantially prejudicial to the ability of the Indemnifying Party to defend against such claim or any litigation resulting therefrom, shall relieve such Indemnifying Party of any obligations under this Agreement to the extent such Indemnifying Party is damaged solely as a result of such failure to give notice, but such failure shall not relieve such Indemnifying Party of any of its obligations otherwise than under this Agreement. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 8. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC which may permit the sale of any outstanding Shares to the public without registration, the Company agrees after any registration to use its best efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act, as long as it is subject to such reporting requirements. 9. Transfer of Registration Rights. Subject to the limitations and restrictions on transferability of the Shares set forth in the Asset Purchase Agreement, the rights to cause the Company to register a Holder's Shares under this Agreement may be assigned by such Holder (or its assignee) to a transferee that acquires from a Holder (or its assignee) at least fifty percent (50%) or more of the Registrable Securities originally acquired by the transferring Holder, provided that the Company is given notice by the Holder at the time of such transfer stating the name and address of the transferee and identifying the securities with respect to which these rights are being assigned. 10. "Market Stand-Off" Agreement. Holder agrees, if requested by the Company or an underwriter of Common Stock (or other securities) of the Company, not to sell or otherwise transfer or dispose of any Shares of the Company held by the Holder (other than those included in the registration) during the 120-day period following the effective date of a registration statement of the Company filed under the Securities Act. E-42

11. Termination of Registration Rights. The obligations of the Company to register the Registrable Securities pursuant to this Agreement shall terminate at the earlier of seven (7) years from the date hereof or, for any Holder, when that Holder is able to sell the Shares pursuant to SEC Rule 144 within a period of twelve (12) months. 12. Modifications and Waivers. This Agreement may not be amended or modified, nor may the rights of any party hereunder be waived, except by a written document that is executed by the Purchasers holding a majority of the Registrable Securities. No waiver of any provision of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof, nor shall any waiver constitute a continuing waiver. 13. Successors. This Agreement is and shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided, however, that neither the Company nor the Purchasers shall assign this Agreement to any third party, except in the case of the Purchasers in accordance with Section 9 above. 14.
