*  Mr. O'Donnell is deemed to be a beneficial owner of all of the shares of
   Common Stock beneficially held by Exegy due to his position with Exegy as its
   Chairman of the Board, President and Chief Executive Officer. Mr. O'Donnell
   also is an affiliate of entities which own approximately 50% of the voting
   power of Exegy.









                                EXPLANATORY NOTE

      On November 7, 2006, Exegy terminated the Contribution Agreement. As a
result, Exegy no longer has the right to obtain shares of Hyperfeed
Technologies, Inc. (the "Issuer") from PICO and therefore has no beneficial
ownership of shares of Common Stock of the Issuer as of the date hereof. This
Schedule 13D/A is filed pursuant to Rule 13d-2 to reflect such change of
beneficial ownership.

Item 5. Interest in Securities of the Issuer.

           (a)-(c) On August 25, 2006, Exegy obtained the right to acquire the
      shares of Common Stock from PICO pursuant to the Contribution Agreement
      and may have been deemed to be the record and beneficial owner of the
      Common Stock. As a result of the right to acquire the shares of Common
      Stock from PICO pursuant to the Contribution Agreement, the Reporting
      Persons may have been deemed to be the beneficial owners of the Common
      Stock. The Contribution Agreement was terminated on November 7, 2006, and
      Exegy's right to acquire the shares of Common Stock from PICO terminated
      as a result thereof. Accordingly, as of November 7, 2006, Exegy would not
      be deemed to be the record or beneficial owner of any shares of Common
      Stock.


                                    Signature

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
