ITEM 1.01   ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

       On August 10, 2006,  First Banks,  Inc.  ("First Banks" or the "Company")
entered  into a First  Amendment  to the Amended  and  Restated  Secured  Credit
Agreement with Wells Fargo Bank, National Association, as Agent, JP Morgan Chase
Bank, N.A., LaSalle Bank National Association, The Northern Trust Company, Union
Bank of  California,  N.A.,  Fifth Third Bank  (Chicago)  and U.S. Bank National
Association  ("Amended Credit Agreement").  The Amended Credit Agreement,  dated
August 10, 2006 in the amount of $96.0 million, amended the previous Amended and
Restated  Secured Credit Agreement dated August 11, 2005 in the amount of $122.5
million that provided a $15.0 million revolving credit facility,  a $7.5 million
letter of credit  facility and a $100.0 million term loan facility.  The primary
changes to the  structure of the  financing  arrangement  include a reduction of
certain components of the secured credit facilities,  a reduction in the overall
pricing  structure  of the  secured  credit  facilities,  and the renewal of the
revolving credit and letter of credit facilities.

       The Amended  Credit  Agreement  provides a $10.0 million  senior  secured
revolving  credit facility  ("Revolving  Credit") that matures on August 9, 2007
and a $1.0  million  senior  secured  standby  letter  of credit  facility  ("LC
Facility")  that  matures on August 9, 2007,  in addition  to the $85.0  million
senior secured term loan facility ("Term Loan") that matures on August 10, 2008.
The Amended Credit Agreement also provides First Banks an option to increase the
Revolving Credit, which is limited to two increase requests from August 10, 2006
until its  maturity  date,  by an amount of up to $40.0  million  provided  such
increase will not cause the Revolving  Credit to exceed $50.0 million.  Interest
is payable on the outstanding principal loan balances under the Revolving Credit
at a floating  rate equal to either the lender's  prime rate or, at First Banks'
option, the London Interbank Offering Rate ("LIBOR") plus a margin determined by
the outstanding loan balances and First Banks' net income for the preceding four
calendar quarters.  If the loan balances  outstanding under the Revolving Credit
are accruing at the prime rate, interest is payable quarterly in arrears. If the
loan  balances  outstanding  under the  Revolving  Credit are accruing at LIBOR,
interest is payable based on the one, two, three or six-month LIBOR, as selected
by First Banks. First Banks is also subject to a quarterly commitment fee on the
unused portion of the Revolving  Credit.  First Banks had not drawn any advances
on the Revolving Credit as of August 10, 2006. The outstanding principal balance
of the Term Loan was $85.0  million on August 10,  2006.  Interest is payable on
the outstanding principal loan balance of the Term Loan at a floating rate equal
to LIBOR plus a margin  determined  by the  outstanding  loan  balance and First
Banks' net income for the preceding  four  calendar  quarters.  The  outstanding
principal balance of the Term Loan is payable in quarterly  installments of $5.0
million, at a minimum,  with the remainder of the Term Loan balance to be repaid
in full, including any unpaid interest, upon its maturity date.

       The Amended Credit  Agreement  requires  maintenance  of certain  minimum
capital  ratios for First Banks and First Bank,  certain  maximum  nonperforming
assets  ratios  for First  Bank and a minimum  return on assets  ratio for First
Banks. In addition, it contains additional covenants,  including a limitation on
the  amount  of  dividends  on First  Banks'  common  stock  that may be paid to
stockholders.  The Amended Credit Agreement is secured by First Banks' ownership
interest in the capital stock of The San Francisco Company and First Bank.

       First Banks intends to use proceeds of advances  under the Amended Credit
Agreement to refinance  existing debt, for general corporate  purposes,  and for
potential acquisitions.
