Exhibit 10.3 PROMISSORY NOTE AND SECURITY AGREEMENT $1,050,000.00 November 17, 1999 FOR VALUE RECEIVED, AMERICAN ELECTROMEDICS CORP., a Delaware corporation ("Maker"), hereby promises to pay to the order of JUBILEE INVESTORS LLC, a Delaware limited liability company (hereinafter called "Payee"), the principal sum of ONE MILLION FIFTY THOUSAND DOLLARS ($1,050,000) (the "Principal Amount") in lawful money of the United States of America. The Principal Amount shall be payable in full on the earlier to occur of (i) within five business days of the closing date of the initial public offering of the Maker's German subsidiary, Rosch GmbH Medizintechnik ("Rosch"), out of proceeds raised in such financing or (ii) April 30, 2000 (the "Maturity Date"). If the average Closing Bid Price for the shares of common stock of the Maker exceeds $3.00 per share for the five (5) trading days prior to the Maturity Date, then the Principal Amount payable hereunder shall be reduced to $700,000. The term "Closing Bid Price" means, for the Maker's common stock as of any date, the closing bid price on the principal securities exchange or trading market where the Maker's common stock is listed or traded as reported by Bloomberg, L.P. ("Bloomberg"), or, if applicable, the closing bid price of the Maker's common stock in the over-the- counter market on the electronic bulletin board for such security as reported by Bloomberg, or, if no closing bid price is reported for the Maker's common stock by Bloomberg, then the average of the bid prices of any market makers for such security as reported in the "pink sheets" by the National Quotation Bureau, Inc. If the Closing Bid Price of the Maker's common stock cannot be calculated on such date on any of the foregoing bases, the Closing Bid Price of the Maker's common stock on such date shall be the fair market value as mutually determined by the Maker and Payee. "Trading day" shall mean any day on which the Maker's common stock is traded for any period on the principal securities exchange or other securities market on which the common stock is then being traded. The following additional terms shall govern this Promissory Note and Security Agreement (this "Note"): 1. This Note is executed and delivered to Payee by Maker in exchange for 350 shares of Convertible Preferred Stock, Series A of the Maker held by Payee as more fully set forth in the Securities Exchange Agreement, dated November 17, 1999, between Maker and Payee (the "Securities Exchange Agreement"). 2. This Note may be prepaid in part from time to time or in full at any time in cash without penalty. All prepayments shall be applied to the reduction of principal. The parties agree that imputed interest is included in the principal amount of this Note. 3. All cash distributions, license fees, royalties and other revenue or consideration received in respect of, or cash proceeds received on the sale or license of, the Collateral (as hereinafter defined) shall be applied, at the option of the Payee, to the prepayment of the entire unpaid Principal Amount of this Note and Maker shall deliver to Payee all such amounts promptly upon receipt thereof, provided, however, that for every $2 of the Principal Amount that is repaid pursuant to this section there shall be a reduction to the Principal Amount of an additional $ 1. 4. Principal shall be paid in lawful currency of the United States, in immediately available funds via wire transfer to an account designated by Payee, or at such other place or to such other person as Payee may designate in a written notice to Maker. 5. As security for the full, prompt and complete payment of all principal on this Note, Maker hereby pledges, assigns and grants to Payee a continuing first priority security interest valid throughout the world, except as expressly limited, in the intellectual property listed on Schedule A (the "Collateral"). Until all amounts secured thereby shall have been repaid in full, the Maker shall execute such further documents and instruments and take such further steps as may be required by Payee to perfect and protect such security interest. Maker shall bear any costs related to the perfection and protection of such security interest. 6. Each of the following shall constitute an "Event of Default" within the meaning of this Note: (a) Maker shall fail or refuse to make payment in full of the Principal Amount due hereunder on the Maturity Date; (b) Maker or any subsidiary of Maker (as principal, guarantor or other surety) shall default in the payment when due of any debt or obligation when due or within any applicable period of grace of any amount of principal, premium or interest on a debt or obligation that is outstanding in a principal amount in the aggregate of at least $250,000; (c) Maker shall default in the performance of any material covenant in this Note or in the Securities Exchange Agreement or if any material representation or warranty made in this Note or in the Securities Exchange Agreement shall have proved to have been false or incorrect in any respect on the date as of which made or shall omit to state any material fact necessary to make the representation and warranty not misleading; provided that before any such event shall become an Event of Default, the Payee shall give written notice to the Maker and the Maker shall have ten (10) days from the receipt of such notice to cure any such event or condition; or (d) (i) Maker or any of its subsidiaries shall make a general assignment for the benefit of its creditors, (ii) entry of a final order adjudicating Maker or any of its subsidiaries bankrupt, (iii) the filing of a voluntary petition by Maker or any of its subsidiaries under any of the provisions of the United States bankruptcy code or similar laws of any jurisdiction, (iv) the filing of any answer or other pleading admitting the material allegations of any petition filed against Maker or any of its subsidiaries in any bankruptcy, insolvency or other such proceeding, (v) the filing of a petition against Maker or any of its subsidiaries under any of the provisions of any bankruptcy laws of the United States or similar laws of any jurisdiction and the failure of such petition to be dismissed within sixty (60) calendar days, (vi) the petition for, or the appointment of, or possession by, a custodian, receiver, liquidator, trustee or sequestrator (or other similar official) of Maker or any of its subsidiaries or any substantial part of its or any such subsidiary's properties or assets, (vii) Maker or any of its subsidiaries shall take any corporate action in furtherance of any of the foregoing, (viii) Maker or any of its subsidiaries shall be generally unable to pay its debts as they mature; or (ix) a final judgment shall be rendered against Maker or any of its subsidiaries for the payment of money at least $250,000 in the aggregate and such judgment shall not be discharged or execution thereon stayed pending appeal within 60 calendar days of entry of such judgment, or, in the event of such a stay, such judgment shall not be discharged within 60 calendar days after such stay expires. 7.

Upon the occurrence of an Event of Default, Payee, in addition to any other rights it may have, shall have the right at any time and from time to time to sell, resell, assign, license, sublicense and deliver, in its discretion, all or any of the Collateral in one or more parcels at the same or different times, and all right, title and interest, claim and demand therein. Payee may purchase all or any of the Collateral being sold. Payee shall give Maker at least ten (10) calendar days' prior notice of the time and place of any public or private sale and of the time after which any private sale or other disposition is to be made, which notice Maker agrees is reasonable. Payee may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned.
