The principal executive offices of the Company are located at 330 South Service Road, Suite 120, Melville, New York 11747. Item 2. Identity and Background ----------------------- This Schedule 13D is being filed by Catherine M. Vaczy ("Ms. Vaczy"). Ms. Vaczy is a citizen of the United States. Ms. Vaczy currently serves as the Executive Vice President and General Counsel of the Company. The Company's principal executive offices are located at 330 South Service Road, Suite 120, Melville, New York 11747. Ms. Vaczy, during the last five years, has not (a) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which Ms. Vaczy was or is now subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration ------------------------------------------------- Pursuant to the Stock Purchase Agreement, dated April 20, 2005, between the Company and Ms. Vaczy (as amended, modified or supplemented, the "Stock Purchase Agreement"), Ms. Vaczy acquired 1,666,666 shares of Common Stock. Ms. Vaczy paid an aggregate of $100,000 for such shares out of Ms. Vaczy's personal funds. Pursuant to the terms of the Stock Purchase Agreement, for a period of 90 days from the date of the Stock Purchase Agreement, Ms. Vaczy has the right to purchase up to an additional $200,000 of Common Stock at a per share price equal to 85% of the average closing price of one share of Common Stock on the National Association of Securities Dealers, Inc. Over-the-Counter Bulletin Board (the "Bulletin Board") (or other similar exchange or association on which the Common Stock is then listed or quoted) for the five (5) consecutive trading days immediately preceding the date of Ms. Vaczy's notice exercising the option; provided, however, that if the Common Stock is not then quoted on the Bulletin Board or otherwise listed or quoted on an exchange or association, the price shall be the fair market value of one share of Common Stock as of the date of issue as determined in good faith by the Board of Directors of the Company; and further provided, that in no event shall the price be less than $.06. Also on April 20, 2005, Ms. Vaczy loaned to the Company the sum of $100,000 and accepted from the Company a promissory note (the "Note"). The Note bears interest at a rate of 15% and matures on April 20, 2006. Ms. Vaczy has the

option to convert the Note into shares of Common Stock at any time up until the 90th day after the date of the Note at a per share price equal to 85% of the average closing price of one share of Common Stock on the Bulletin Board (or other similar exchange or association on which the Common Stock is then listed or quoted) for the five (5) consecutive trading days immediately preceding the date of Ms. Vaczy's notice; provided, however, that if the Common Stock is not then quoted on the Bulletin Board or otherwise listed or quoted on an exchange or association, the price shall be the fair market value of one share of Common Stock as of the date of issue as determined in good faith by the Board of Directors of the Company; and further provided, that in no event shall the price be less than $.06. Following the 90th day after the date of the Note, Ms. Vaczy is obligated, at any time prior to the date of maturity of the Note, to convert the Note into shares of Common Stock unless Ms. Vaczy shall have provided to the Company a notice terminating her employment with the Company pursuant to her Letter Agreement (defined below) with the Company providing for her employment as Executive Vice President and General Counsel. Ms. Vaczy loaned the principal amount of the Note to the Company with her personal funds. Item 4. Purpose of Transaction ---------------------- The acquisition by Ms. Vaczy of the securities described in Item 3 above is for investment purposes. On April 20, 2005 (the "Commencement Date"), simultaneously with the execution of the Stock Purchase Agreement, the Company and Ms. Vaczy entered into a letter agreement (the "Letter Agreement"), pursuant to which the Company appointed Ms. Vaczy as its Executive Vice President and General Counsel. Subject to the terms and conditions of the Letter Agreement, the term of Ms. Vaczy's employment in such capacity will be for a period of three (3) years from the Commencement Date (the "Term"). In consideration for Ms. Vaczy's services under the Letter Agreement, Ms. Vaczy will be entitled to receive an annual salary of $155,000 during the first year of the Term, a minimum annual salary of $170,500 during the second year of the Term, and a minimum annual salary of $187,550 during the third year of the Term. Ms. Vaczy and the Company have agreed that from the Commencement Date until the 90th day thereafter (the "Initial 90 Day Period"), Ms. Vaczy's salary will be paid to her at a rate of 50% of the annual rate and accrue as to the remainder. At the end of the Initial 90 Day Period, and at the end of each additional 90 day period thereafter, whether to continue to accrue salary at this rate and provision for payment of accrued amounts will be discussed in good faith. Payment of accrued salary may be made in cash, or, upon mutual agreement, shares of Common Stock. Any shares of Common Stock issued in payment of accrued salary shall have a per share price equal to the average closing price of one share of Common Stock on the Bulletin Board (or other similar exchange or association on which the Common Stock is then listed or quoted) for the five (5) consecutive trading days immediately preceding the date of issue of such shares; provided, however, that if the Common Stock is not then quoted on the Bulletin Board or otherwise listed or quoted on an exchange or association, the price shall be the fair market value of one share of Common Stock as of the date of issue as determined in good faith by the Board of Directors of the Company. The number of shares of Common Stock for any issuance in payment of accrued salary shall be equal to the quotient of the amount of the accrued salary divided by the price. The shares issued will be subject to a one-year lock of up as of the date of each grant and shall be registered with the Securities and Exchange Commission on a Registration Statement on Form S-8.

Pursuant to the Letter Agreement, on the Commencement Date, Ms. Vaczy was granted an option to purchase 150,000 shares of Common Stock (the "Option") pursuant to the Company's 2003 Equity Participation Plan (the "2003 EPP"). The Option is an Incentive Stock Option pursuant to Section 422 of the Internal Revenue Code of 1986, as amended, and is represented by a stock option agreement. The Option has an exercise price equal to $0.10 per share and vests and becomes exercisable as to 50,000 shares on each of the first, second and third year anniversaries of the Commencement Date and remains exercisable as to any vested portion thereof in accordance with the terms of the 2003 EPP and the stock option agreement. In the event Ms. Vaczy's employment with the Company is terminated prior to the end of its Term by the Company without cause or by Ms. Vaczy for good reason, the option shall vest and become immediately exercisable in its entirety and remain exercisable in accordance with its terms. Item 5. Interest in Securities of the Issuer ------------------------------------ As of April 20, 2005, there were 45,540,900 shares of Common Stock outstanding. As of such date, Ms. Vaczy owned an aggregate of 6,666,665 shares of Common Stock, or 13.2% of the outstanding shares of Common Stock. Ms. Vaczy has the sole power to vote or to direct the vote and the sole power to dispose or to direct the disposition of all of such shares. Except as described in Item 3 of this Schedule 13D, during the past sixty days, there were no purchases of shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, by Ms. Vaczy or any person or entity controlled by Ms. Vaczy or any person or entity for which Ms. Vaczy possesses voting control over the securities thereof.
