          (b)  The business address of Dr. Thompson is c/o Senesco Technologies,
               Inc.,  303 George Street,  Suite 420, New  Brunswick,  New Jersey
               08901;

          (c)  The present principal occupation or employment of Dr. Thompson is

               Company;

          (d)  During the last five years,  Dr.  Thompson has not been convicted

               respect to such laws; and

          (f)  Dr. Thompson is a citizen of Canada.

 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").

          Dr.  Thompson  was a  shareholder  of Senesco and  beneficially  owned
          425,000 shares of Common Stock of Senesco.  As a result of the Merger,
          on January 22, 1999, Dr.  Thompson  received  425,000 shares of Common
          Stock of STI  (formerly  Nava),  consisting of 15.74% of the 2,700,008
          shares of STI Common Stock issued and outstanding.

          On September 7, 1999, STI granted to Dr. Thompson  options to purchase
          40,000  shares of STI Common  Stock,  on a post stock  split  adjusted
          basis (as described  below),  at an exercise  price equal to $3.85 per
          share.  Dr. Thompson  received such options as  consideration  for his
          services  as an  executive  officer  of  STI.  All  such  options  are
          currently exercisable.

          On September 29, 1999, STI declared a two-for-one  forward stock split
          of its issued and  outstanding  Common  Stock  and,  as a result,  Dr.
          Thompson's  holdings of STI Common Stock  increased to 850,000 shares,
          excluding any options to purchase shares of STI Common Stock.



                               (Page 3 of 6 Pages)


          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.

          On December 1, 2001, the Company  granted to Dr.  Thompson  options to
          purchase  80,000 shares of Common Stock pursuant to the Company's 1998
          Stock Incentive Plan, as amended,  at an exercise price equal to $2.05
          per share.  One-third  (1/3) of such options were  exercisable  on the
          date of grant,  one-third (1/3) of such options became  exercisable on
          December 1, 2002,  and  one-third  (1/3) of such options  shall become
          exercisable on December 1, 2003. Dr. Thompson received such options as
          consideration for his services as an executive officer of the Company.

 ITEM 4.  PURPOSE OF TRANSACTION.

          On December 1, 2002,  one-third (1/3) of the 80,000 options granted to
          Dr.  Thompson on December 1, 2001 pursuant to the Company's 1998 Stock
          Incentive  Plan, as amended,  at an exercise  price equal to $2.05 per
          share, became exercisable.

          Dr. Thompson 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.  Additionally, Dr. Thompson may dispose of shares of Common
          Stock.  Dr. Thompson will continue to consider his equity interests in
          the  Company  and he  reserves  the right to  formulate  such plans or
          proposals,  and to take such  action,  as he may deem  appropriate  in
          light of future circumstances.

          Except as set forth  above,  Dr.  Thompson  does not 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.


                               (Page 4 of 6 Pages)


 ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

          (a)  Dr.  Thompson  beneficially  owns 665,334 shares of Common Stock,
               including  options to purchase 93,334 shares of Common Stock. Dr.
               Thompson's  665,334 shares of Common Stock represents 5.6% of the
               issued and  outstanding  shares of Common Stock of the Company as
               of December  31,  2002,  based on  11,880,045  shares  issued and
               outstanding and assuming the exercise of all options  exercisable
               within 60 days held by Dr. Thompson.

          (c)  In 2002,  the  percentage  of the issued and  outstanding  Common
               Stock  beneficially  owned by Dr. Thompson was reduced due to the
               Company's private placements of Common Stock.

          (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

          ventures,  loan or option arrangements,  puts or calls,  guarantees of
