INFORMATION TO BE INCLUDED IN REPORT ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS. On April 12, 2001, pursuant to an "Asset Purchase Agreement" dated April 12, 2001, Gentner Communications Corporation (the "Registrant") sold substantially all of the assets (the "Transaction") of its Remote Facilities Management division (the "RFM division") to Burk Technology of Littleton, MA ("Burk"). Burk is a privately-held developer and manufacturer of broadcast facility control systems products (the "Business"). In the Transaction, the Registrant retained all of the liabilities of the RFM division, other than with respect to (i) unfilled customer orders, and (ii) warranty obligations of Registrant to its existing customers, and for inventory sold to Burk in the Transaction. Burk will perform warranty service on a burdened cost basis, payable by Registrant. As part of the Transaction, Registrant agreed not to compete with Burk in the Business for a period of five (5) years. The Registrant will account for the sale of these assets under the purchase method of accounting. The assets were sold to Burk for $3.2 million, including $750,000 at closing, and $1.75 million in the form of a seven (7) year promissory note, with interest at the rate of nine percent (9%) per annum, secured by a subordinate security interest in the personal property of Burk. In addition, up to $700,000 is payable as a commission over a period of up to seven years. The commission is based on a percentage of the increase in net sales experienced by Burk after the closing of the Transaction. The increase will be measured from a base amount derived from historic net sales figures of both Registrant and Burk. The total value of the consideration received for the assets was determined based on arm's length negotiations between the Registrant and Burk, that took into account a number of factors of the business including historic revenues, operating history, products, intellectual property and other factors. There were no material relationships between the Registrant and Burk prior to completion of this transaction. The assets sold were used in the development and support of the Registrant's component technology products for broadcast facility control systems. ITEM 7.

The per annum rate of interest to be charged shall be fixed at the rate of nine percent (9.0%) per annum. Debtor will commence paying interest and principal totaling Ninety-Three Thousand Three Hundred Sixty-Six and Thirteen One Hundredths Dollars ($93,366.13) on a quarterly basis beginning with the first day of the first full calendar quarter which occurs at least 180 days from the date of this note, as more specifically enumerated on the attached Schedule A. Each payment shall be applied: first to any late fees; second to interest then due on the unpaid balance of principal; and only then to reduction of principal. Schedule A attached to this Note provides for twenty-six consecutive calendar quarterly payments. Creditor agrees that the Borrower may declare a quarterly payment deferral applicable to the next quarter if the aggregate "Net Sales" of the "Combined Business" (as to the two quoted terms are defined in the Commission Agreement of today's date) fails to meet or exceed $1,100,000 per calendar quarter or such pro rated portion of this amount for any partial calendar quarter. Any payments so deferred shall be paid on a calendar quarterly basis commencing after completion of the projected sixteen quarters identified at Schedule A with interest calculated on the deferred amount at 9% per annum.

In any event, all indebtedness, including all E-27

unpaid or deferred principal, interest, and unpaid fees and expenses, if not sooner paid, shall be due and payable seven (7) years from the date of this Note. The Debtor shall have the right to prepay this Note in part or in full without penalty.

This Note shall become due and payable, including the entire balance of principal and interest then accrued and unpaid, prior to maturity at the option (exercisable regardless of any prior forbearance or indulgences) of the holder hereof upon any one or more of the following events, the occurrence of any of which shall be a default: a) failure to make any payment due under this Note which is not cured within fifteen (15) days from the date of the mailing of notice of such default by Creditor to Debtor; or b) default in the performance or observance of any of the agreements, covenants or conditions of this Note, Commission Agreement or the Security Agreement, all of today's date, not cured within thirty (30) days from the date of the mailing of notice of such default by Creditor to the Debtor; c) institution of bankruptcy or insolvency proceedings by the Debtor, or against the Debtor by a third party when such action is not removed within fifteen (15) days of institution; or d) lapse or termination of Debtor's interest in any collateral securing this Note except such collateral as is: a) replaced by collateral of equal or greater value; or b) otherwise sold or diminished in the ordinary course of business. The Debtor also agrees to pay a late charge for payments of interest and principal made fifteen (15) days after their due date assessed at three percent (3%) of the overdue amount. Such late charge payments are made for the purpose of compensating the Creditor for its administrative costs and expenses in handling late payments and losses in connection therewith. This provision is not intended to provide a grace period for any payment otherwise due and payable and shall not constitute a waiver by the Creditor to insist upon the strict performance of any of the conditions of this Note or the Security Agreement or to declare any event of default for any payment not made when it was due and payable. In case this Note shall not be paid in full whenever it shall become due, the Debtor agrees to pay all costs and expenses of collection, including court costs and reasonable attorneys' fees. The indebtedness evidenced by this Note is subject to the provisions of a Security Agreement in the assets described in such Agreement. E-28

CERTAIN RIGHTS; EFFECT OF EVENT OF DEFAULT (a) Obligation Due; Commitments Terminated. If an Event of Default shall occur, then, notwithstanding any other agreement now or hereafter existing, and subject to the terms and conditions of this Agreement (including the provisions with respect to subordination and the Senior Indebtedness), Secured Party may declare all Obligations immediately due and payable and exercise any remedies provided herein. (b) Actions Regarding Collateral.

(the "Buyer"), a Massachusetts corporation having a usual place of business at 7 Beaver Brook Road, Littleton, MA 01460 BACKGROUND: The Parties have executed an Asset Purchase Agreement (the "Asset Agreement") by which Buyer has purchased Seller's Remote Facilities Management Product Line (the "Business").

applicable for the calendar year in question (or portion thereof if $700,000 in aggregate Commission Payments are earned by Seller prior to December 31, 2007) by the number obtained after subtracting the Annual Combined Commission Base for such year (or portion thereof) from Buyer's final Net Sales for the Combined Business during such year (or portion thereof). f) "Net Sales" shall be the gross invoice amount invoiced by Buyer for the Combined Business during the period in question less any deductions for insurance, returns, freight, or discounts on such sales during this same period. g) "Seller's Base Amount" is initially $2,478,000--which resulted from calculating 90% of Seller's FY 2000 sales from the Business. i) "Commission Payment Period" is the period during which Commissions are earned by Seller as provided in paragraph d) of this Section 1. 2. Commission Payments. Beginning in calendar year 2002, Seller shall be entitled to Commission Payments which shall be calculated and paid as follows: Commencing on January 31, 2003 and each January 31 thereafter (or the next succeeding business day if such date is not a business day), during the Commission Payment Period, Buyer shall provide Seller with the Final Annual Commission together with documentation summarizing the calculation resulting in this payment. (If Seller earns $700,000 in total Commission Payments prior to December 31, 2007, the Final Annual Commission and documentation shall be provided by Buyer to Seller within 45 calendar days of the date on which the $700,000 total is earned.) [Deletion] 3. Accounting. Representatives of Seller shall have reasonable access upon reasonable notice during normal business hours to such books and records of Buyer pertaining thereto for the purpose of verifying the calculation of the Annual Commission. 4.

The Parties agree to utilize the courts only to: a) enforce the final decision resulting from application of this Section; and b) obtain such injunctive relief as is necessary to avoid irreparable harm pending such final decision under this Section.

It is intended and agreed that in the event any portion of this Covenant is judicially held to be invalid or unenforceable, for whatever reason, such invalid portion of this Covenant shall be treated and considered modified, revised and limited in such manner and to such extent as may be necessary to make that portion and the remaining portions of this Covenant valid and enforceable to the maximum extent permitted by law. Any court of competent jurisdiction shall have the power to modify this Covenant in order to make it conform to what the Court shall determine to be reasonable for the terms of this Covenant rather than rendering the entire Covenant invalid.

Confidential Information, which at all times shall remain the property of Buyer and shall not be used or disclosed by Seller's employees without the prior written consent of Buyer. 3. SELLER'S ENFORCEMENT ASSISTANCE. Seller agrees to use reasonable efforts to enforce the Proprietary Rights with respect to the Business on Buyer's behalf, to the extent enforceable in light of the language of the Non-Compete Agreements: as long as an employment relationship continues; at the time of termination of such relationship; and in the case of the Non-Disclosure and Invention Rights, after such relationship ceases. 4. IRREPARABLE HARM. Seller acknowledges and agrees that breach of any of the covenants, conditions or provisions contained in this Agreement may result in irreparable harm and damage to Buyer and such harm and damage will be extremely difficult or impossible to quantify. Accordingly, Seller hereby consents to the jurisdiction of any court having equitable jurisdiction and to the entry of an injunction, temporary or permanent, enjoining it them from any further violations of this Agreement. 5.

All rights, powers and remedies of the Parties hereunder (or by law, equity or statute permitted) are cumulative and may, to the extent permitted by law, be exercised concurrently or separately.

No failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof or an acquiescence therein or of, any similar breach or default thereafter occurring; nor shall any single or partial exercise by any Party of any right, power or remedy hereunder preclude any other or future exercise thereof or the exercise of any other right or remedy. Nor shall any waiver of any single breach or default be deemed a waiver or any breach or default theretofore or thereafter occurring. Any waiver, permit or consent or approval of any kind or character on the part of either Party hereto of any breach or default under this Agreement or any other waiver on the part of any Party hereto of any provision or condition of this Agreement, must be in writing and shall be effective only to the extent specifically allowed by such writing. 6.
