Item 3. Source and Amount of Funds or Other Consideration

     The shares of Common Stock were  originally  acquired  more than five years
prior to the date of this  amended  Schedule 13D (except to the extent that such
shares of Common Stock were subsequently transferred among members of the family
of David M.  Goldenberg  and trusts or entities  controlled by such persons) and
the  source  and  amount  of funds  previously  expended  is thus not  material.
Substantially all of the shares were acquired upon the initial capitalization of
Immunomedics,  Inc.  From time to time  since the  acquisition  of such  shares,
certain of such  shares  have been  transferred  among  members of the family of
David M.  Goldenberg  and trusts or entities  controlled by such  persons.  This
Schedule  13D  amendment  does not reflect any  acquisitions  of Common Stock of
Immunomedics,  Inc. made by Dr. Goldenberg.  Rather,  this amendment is filed to
reflect a change in the direct ownership of shares of Common Stock  beneficially
owned by Dr.  Goldenberg  resulting  from (i) the transfer by Dr.  Goldenberg of
1,500,000  shares of Common Stock to a grantor  retained  annuity  trust for his
benefit, (ii) transfers by Dr. Goldenberg among members of his family and trusts

                              Page 5 of 11 pages




or entities controlled by such persons,  (iii) the disposition by Dr. Goldenberg
of 34,725  shares of  Common  Stock in  exchange  for an 18.3%  interest  in IBC
Pharmaceuticals,  Inc., a 73% owned subsidiary of  Immunomedics,  Inc., (iv) Dr.
Goldenberg no longer  serving as an officer or director of Escalon  Corporation,
and (v) Dr.  Goldenberg no longer serving as an officer,  director or trustee of
Escalon  Foundation.   This  amendment  also  adds  Cynthia  L.  Sullivan,   Dr.
Goldenberg's wife, as a reporting person on this Schedule 13D.

Item 4. Purpose of Transaction

     Neither Dr.  Goldenberg nor Ms. Sullivan has any present plans or proposals
of the types set forth in paragraphs  (a) through (j) of Item 4 of Schedule 13D.
Dr.  Goldenberg  and Ms.  Sullivan  may, from time to time,  acquire  additional
shares of Common  Stock or  dispose  of all or a portion of the shares of Common
Stock beneficially owned by him or her, as applicable, either in the open market
or in privately  negotiated  transactions.  Dr.  Goldenberg and Ms. Sullivan may
also obtain  additional  shares of Common  Stock upon the  exercise of the stock
options described in Item 5 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

     (i)  As of October 9, 2002, Dr.  Goldenberg  beneficially  owned  7,862,183
