                                   WITNESSETH:

     WHEREAS,  Optionee  has  rendered  and will  continue  to  render  valuable
services  (the  "Services")  to IDM in  connection  with the  operation of IDM's
business;  and WHEREAS, in order to compensate Optionee for the Services, and as
inducement  for continuing to provide the Services,  IDM and Optionee  desire to
evidence  IDM's  agreement  to grant  certain  options to Optionee as  described
herein.  NOW THEREFORE,  for and in  consideration  of the foregoing and for the
mutual covenants and consideration described herein, the parties hereto agree as
follows: 

     1.  Services.  Optionee has assisted,  and shall assist,  IDM by performing
consulting services  including:  (i) analyze and assess alternatives for IDM, as
presented by IDM, for raising capital,  including public or private offerings of
IDM's securities;  and (ii) provide  introductions to professional  analysts and
money managers.

     2. Option. As consideration for Optionee rendering the Services to IDM, IDM
hereby grants to Optionee an option (the "Option"),  exercisable immediately and
for the  duration  of this  Agreement,  to acquire  up to 100,000  shares of the
common stock of IDM (the "Option  Shares",  the Option and the Option Shares are
referred to collectively as the "Registrable Securities") at $3.50 per share.

     3. Term. The term of this Agreement shall commence on the date first stated
above and shall expire on the fifth anniversary of such date.

     4. Piggyback  Registration  Rights.  IDM covenants and agrees with Optionee
that  commencing six (6) months after the date hereof and at any time thereafter
during the term of the Option, it proposes to file a registration statement with
respect  to any  class of  equity  or  equity-related  security  (other  than in
connection with an offering to the Company's  employees or in connection with an
acquisition, merger or similar transaction) under the Securities Act of 1933, as
amended,  in a  primary  registration  on behalf  of IDM  and/or in a  secondary
registration on behalf of holders of such securities and the  registration  form
to be used may be used for registration of the Registrable Securities,  IDM will
give  prompt  written  notice  (which  in the case of a  registration  statement
pursuant to the exercise of demand  registration rights shall be within ten (10)
business  days after IDM's receipt of notice of such exercise and, in any event,
after IDM's receipt of notice of such  exercise  and, in any event,  shall be at
least  thirty  (30) days  prior to such  filing) to the  holders of  Registrable
Securities at the addresses  appearing on the records of IDM of its intention to
file a  registration  statement  and will offer to include in such  registration
statement  such number of Registrable  Securities  with respect to which IDM has
received written  requests for inclusion  therein within ten (10) days after the
giving  of  notice  by IDM,  subject  to the  right of IDM to  exclude  from the
registration  statement some or all of the  Registrable  Securities if, and only
if,  IDM has  been  advised  in  writing  by any  underwriter  named in any such
registration  statement  that the  distribution  of the  Registrable  Securities
requested  to  be  included  in  the  registration  statement  would  materially
adversely  affect the  distribution  of securities by IDM  contemplated  by such
registration  statement.  All registrations requested pursuant to this Section 4
will be made  solely at IDM's  expense,  other  than  discounts  or  commissions
relating to the sale of the Registrable  Securities and fees, if any, of counsel
for the holder of the Registrable Securities.  This Section is not applicable to
a  registration  statement  filed  by IDM on Forms  S-4 or S-8 or any  successor
forms. IDM's obligations under this Section 4 shall be conditioned upon a timely
receipt by IDM in writing  of: (i)  information  as to the terms of such  public
offering  furnished  by or on behalf of each  holder of  Registrable  Securities
intending to make a public offering of his, her or its  Registrable  Securities,
and (ii) such other information as IDM may reasonably require from such holders,
or  any  underwriter  for  any of  them,  for  inclusion  in  such  registration
statement.
