Common Stock, Convertible Debentures and Warrants of Iteris, Inc.
151 South Manchester Avenue
Anaheim, CA 92802

--------------------------------------------------------------------------------
Item 2.  Identity and Background.

        (a)       SACC Partners LP (Delaware limited partnership) Riley
                  Investment Management LLC (Delaware limited liability
                  company) B. Riley & Co., Inc. (Delaware corporation)
                  Bryant R. Riley (individual residing in California)

        (b)       11100 Santa Monica Blvd. Suite 800 Los Angeles, CA 90025

        (c)       Mr. Riley owns all of the outstanding shares of B. Riley &
                  Co., Inc. ("BRC"), an NASD member broker-dealer. Mr. Riley
                  also manages and owns all of the outstanding membership
                  interests of Riley Investment Management LLC ("RIM"), a
                  California registered investment adviser. RIM is the
                  investment adviser to and general partner of SACC Partners LP
                  ("SACC"). Each entity is located at the address specified in
                  (b) above.

        (d)       None

        (e)       None

        (f)       United States

--------------------------------------------------------------------------------
Item 3.  Source and Amount of Funds or Other Consideration.

SACC's purchases were made with SACC partnership funds. BRC's purchases were
made with BRC corporate funds. Mr. Riley's purchases were made with personal

--------------------------------------------------------------------------------
Item 4.  Purpose of Transaction.

SACC, BRC and Mr. Riley acquired the issuer's shares for investment purposes.

      (a)        SACC owns 1,635,366 shares of Iteris Holdings common stock and
           341,713 warrants. Because RIM has sole voting and investment power
           over SACC's security holdings, Mr. Riley, in his role as the sole
           manager of RIM, controls RIM's voting and investment decisions and
           may be deemed to have beneficial ownership of the stock and
           warrants.

                  BRC owns 379,303 shares of Iteris Holdings common stock and
           57,227 warrants. Because Mr. Riley has sole voting and investment
           power over BRC's security holdings, both BRC and Mr. Riley may be
           deemed to have beneficial ownership of the stock and warrants.

                  Mr. Riley personally owns 186,533 shares of Iteris common
           stock and 76,412 warrants. Mr. Riley also controls a total of
           $320,000 face value convertible debentures and 20,272 warrants as
           custodian for his children; however Mr. Riley disclaims beneficial
           ownership of the custodial holdings.

     (b)         With respect to all of the shares that are held by each of SACC
           and BRC, Mr. Riley has sole power to vote and dispose or direct the
           disposition of the shares

     (c)        Please see Exhibit A for SACC's, BRC's and Mr. Riley's
           transactions within the past sixty (60) days.

     (d)        None

     (e)        Not applicable

--------------------------------------------------------------------------------
Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

The relationships between Mr. Riley, SACC, RIM and BRC are described above under
Item 2(c) above. There is no written agreement among the reporting parties
regarding the Iteris Holdings positions.

--------------------------------------------------------------------------------
Item 7.  Material to be Filed as Exhibits.

There are no written agreements amongst the parties relating to the filing of
this joint acquisition statement, nor are there any written agreements,
contracts, arrangements, understandings, plans or proposals relating to (1) the
borrowing of funds to finance the acquisition of shares, (2) the acquisition of
