any Introduced Account directly in order to obtain any necessary or appropriate
documentation, but exercise of such right by Cowen shall not affect Introducing
Broker's obligations hereunder. Introducing Broker hereby agrees to indemnify
and hold Cowen harmless from expenses (including reasonable attorneys' fees and
expenses) arising out of or relating to the failure of Introducing Broker to
obtain or maintain such necessary, required or appropriate agreements and
documentation.

      2. Introducing Broker shall provide Cowen with such new account
information as shall be required by Cowen to fulfill its service obligations
under the Clearing Agreement. Except for accounts opened by tape-to-tape
conversion, such information shall be provided through Cowen's computer system
if direct input is available to Introducing Broker. If direct input is not so
available to Introducing Broker. If direct input is not so either case (but not
with respect to accounts opened by tape-to-tape conversion), Introducing Broker

customers" and to properly supervise its own employees and the Introduced
Accounts. Although Cowen may prepare or possess certain surveillance records fo
r its own benefit or purposes which may include data relating to the Introduced
Accounts, or may prepare or possess compliance or surveillance records for use

its contents.

customers, Introducing Broker is hereby authorized to sign checks on bank
