ITEM 1. SECURITY AND ISSUER. The title of the class of equity securities to which this statement relates is common stock, $.01 par value (the "Common Stock"), of Senesco Technologies, Inc., a Delaware corporation (the "Company"). The address of the principal executive offices of the Company is 34 Chambers Street, Princeton, New Jersey 08542. ITEM 2. IDENTITY AND BACKGROUND. This Statement on Schedule 13D is being filed by The Umbrella Project, L.L.C., a New Jersey limited liability company ("Umbrella"). The address of Umbrella's principal place of business and principal office is 95 Old Dutch Road, Far Hills, NJ 07931. Umbrella's principal business is a holding company which invests in a variety of business entities conducting various activities. Umbrella's sole member is Phillip O. Escaravage. Mr. Escaravage is a citizen of Canada but a resident alien of the United States. During the last five years, neither Umbrella nor Mr. Escaravage has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), and Umbrella or Mr. Escaravage was not a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which proceeding it was or is 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. On October 9, 1998, Senesco, Inc., a New Jersey corporation ("Senesco"), Nava Leisure USA, Inc., an Idaho corporation ("Nava"), Nava Leisure Acquisition Corp., a New Jersey corporation and wholly-owned subsidiary of Nava ("NAC"), and the Principal Stockholders (as defined therein), entered into an Agreement and Plan of Merger, providing for the merger of NAC with and into Senesco, and the issuance to the shareholders of Senesco one newly issued share of Common Stock of Nava for each share of Common Stock of Senesco whereby the shareholders of Senesco acquired a majority of the issued and outstanding shares of Common Stock of Nava (the "Merger"). The Merger was consummated on January 22, 1999, the date upon which the Certificate of Merger filed with the Secretary of State of the State of New Jersey was declared effective. Upon the consummation of the Merger, Senesco was the surviving corporation and remained a subsidiary of Nava which changed its name to Senesco Technologies, Inc., an Idaho corporation ("STI"). Umbrella was a shareholder of Senesco and beneficially owned 933,476 shares of Common Stock of Senesco. As a result of the Merger, on January 22, 1999, Umbrella received 933,476 shares of Common Stock of STI (formerly Nava), consisting of 34.57% of the 2,700,008 shares of STI Common Stock issued and outstanding. On September 7, 1999, STI granted to Mr. Escaravage options to purchase 40,000 shares of STI's Common Stock, on a post stock split adjusted basis (as described below), at an exercise price equal to $3.85 per share. Mr. Escaravage received such options as consideration for his services as a Director of STI. All such options are currently vested. On September 29, 1999, STI declared a two-for-one forward stock split of its issued and outstanding Common Stock and, as a result, Umbrella's holdings of STI Common Stock increased to 1,866,952 shares. On September 30, 1999, STI merged with and into the Company, for the sole purpose of reincorporating the corporation from the State of Idaho to the State of Delaware. Pursuant to a Common Stock Purchase Agreement by and between the Company and Umbrella, dated as of January 31, 2000, Umbrella purchased 34,737 shares of the Company's restricted Common Stock for an aggregate purchase price of $100,000, using its working capital.

ITEM 4. PURPOSE OF TRANSACTION. Mr. Escaravage is the founder of Senesco and a current director of the Company. The acquisition of the shares of the Company's Common Stock reported herein were made to acquire a voting interest in the Company and an equity investment interest in the Company. Umbrella and/or Mr. Escaravage may from time to time, depending upon market conditions, the state of affairs of the Company and other factors, acquire additional shares of Common Stock of the Company, subject to applicable laws and to the availability of shares at prices deemed favorable. Alternatively, Umbrella and/or Mr. Escaravage may dispose of shares of the Company's Common Stock. Umbrella and/or Mr. Escaravage will continue to consider their respective equity interests in the Company and they reserve the right to formulate such plans or proposals, and to take such action, as may seem appropriate in light of future circumstances. Except as set forth above, neither Umbrella nor Mr. Escaravage have any present plans or intentions which would result in or relate to any of the following: (a) The acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (b) An extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company; (c) A sale or transfer of a material amount of assets of the Company; (d) Any change in the present board of directors or management of the Company, including any plans or proposals to change the number or terms of directors or to fill any existing vacancies on the board; (e) Any material change in the present capitalization or dividend policy of the Company; (f) Any other material change in the Company's business or corporate structure; (g) Changes in the Company's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; (h) Causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) A class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) Any action similar to any of those enumerated above. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) Umbrella is the beneficial owner and record holder of 1,840,465 shares of the Company's Common Stock. Umbrella disclaims any beneficial interest in the option to purchase 40,000 shares of the Company's Common Stock held by Mr. Escaravage. Umbrella's 1,840,465 shares of Common Stock represents 23.4% of the issued and outstanding shares of Common Stock of the Company, based on 7,872,626 issued and outstanding shares reported on the Company's proxy statement filed with the Securities and Exchange Commission on October 27, 2000. Page 4 of 6 Pages

Mr. Escaravage is the beneficial owner of options to purchase 40,000 shares of the Company's Common Stock that are exercisable within 60 days. The option to purchase 40,000 shares of the Company's common stock held by Mr. Escaravage represents less than 1% of the issued and outstanding shares of Common Stock of the Company, based on 7,872,626 issued and outstanding shares reported on the Company's proxy statement filed with the Securities and Exchange Commission on October 27, 2000. (b) Umbrella has the sole power to vote and the sole power to dispose of 1,840,465 shares of the Company's Common Stock held solely by it. Mr. Escaravage has the sole power to vote and the sole power to dispose of and options to purchase 40,000 shares of the Company's Common Stock held solely by him. (c) On September 7, 1999, the Company granted to Mr. Escaravage options to purchase 40,000 shares of the Company's Common Stock, at an exercise price equal to $3.85 per share, with 50% of the options vesting on the date of grant and 50% of the options vesting on June 30, 2000. Such options were issued to Mr. Escaravage in consideration for his services as a director of the Company. Pursuant to a Common Stock Purchase agreement dated as of January 18, 2000, Umbrella sold 61,224 shares of the Company's Common Stock to an unrelated third party for an aggregate purchase price of $150,000. Pursuant to a Common Stock Purchase Agreement by and between the Company and Umbrella, dated as of January 31, 2000, Umbrella purchased 34,737 shares of the Company's Common Stock for an aggregate purchase price of $100,000. The percentage of the issued and outstanding Common Stock of the Company beneficially owned by Umbrella was materially reduced due to (i) the sale by Umbrella of 61,224 shares of Common Stock to an unrelated third party, and (ii) the Company's private placement of 1,471,700 shares of its restricted Common Stock, completed in June, 2000. (d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, such securities. (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH THE ISSUER.
