PART III -- NARRATIVE

State below in reasonable  detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR,
N-CSR, or the transition  report or portion  thereof,  could not be filed within
the prescribed time period.

Persons who are to respond to the  collection of  information  contained in this
form are not required to respond unless the form displays a currently  valid OMB
control number.

San Joaquin  Bancorp (the  "Company") has determined that it is unable to timely
file its Quarterly  Report on Form 10-Q for the quarter ended September 30, 2009
(the  "September  2009 Form 10-Q") within the  prescribed  time period,  without
unreasonable effort or expense for the reasons described below under "Seizure of
San  Joaquin  Bank," and  because the  Company  lacks the  available  resources,
qualified  personnel and necessary records needed to prepare,  complete and file
the financial statements and other information called for in connection with the
September 2009 Form 10-Q.

Seizure of San Joaquin Bank

As  previously  reported,  on October 16, 2009,  the  California  Department  of
Financial Institutions closed the Company's former subsidiary,  San Joaquin Bank
(the "Bank") and appointed the Federal Deposit Insurance Corporation ("FDIC") as
receiver.   The  FDIC  facilitated  the  transfer  of  the  Bank's  business  by
immediately  entering into a transaction with Citizens  Business Bank,  Ontario,
California,  pursuant  to which it assumed  all of the  deposits of the Bank and
purchased  essentially all of the Bank's assets.  The Company's  principal asset
and only source of income was the Bank. As previously disclosed,  the Company is
exploring whether to file a voluntary petition for bankruptcy under Chapter 7 of
Title 11 of the United  States Code (the  "Bankruptcy  Code") in an  appropriate
United States Bankruptcy  Court. As a result,  the Company expects to conduct no
business other than in connection with its corporate and disclosure  obligations
under law and  determining  whether and when to file for bankruptcy  pursuant to
the Bankruptcy Code or, alternatively, to wind-up and dissolve the Company in an
orderly manner pursuant to California law.

During the period  leading up to the  seizure of the Bank,  the Company had been
engaged in addressing the deteriorating  financial condition of the Bank and the
Company and  conserving and managing cash  resources.  As a result of the Bank's
seizure,  the board of directors of the Company is now  developing  plans for an
orderly  transition  and  dissolution  of the Company.  Since the seizure of the
Bank,  virtually all of the Company's  employees  have resigned and Bank records
necessary for the  completion of the September  2009 Form 10-Q are now under the
control of either the FDIC or Citizens  Business Bank.  Based upon the fact that
the Company's  liabilities  substantially  exceeded the  Company's  assets as of
October 31, 2009 and there is no reasonable basis to assume that the liquidation
of the Bank's assets by the FDIC will result in a distribution to the Company or
for the  Company  to  continue  as a going  concern,  it is  believed  that  the
Company's  equity  securities have no value and any liquidation plan pursuant to
the  Bankruptcy  Code or otherwise  pursuant to California  law, will include no
distributions to the Company's shareholders of cash or property of value.

As a result of the  foregoing,  the Company is unable to file its September 2009
Form 10-Q within the  prescribed  time  period  without  unreasonable  effort or
expense  and,  accordingly,  it will not be able to file such report  within the
permitted 15 day extension period.

PART IV -- OTHER INFORMATION

(1) Name  and  telephone  number  of  person  to  contact  in  regard  to  this
     notification

                Bart Hill               661             281-0360
                ------------------------------------------------
                  (Name)          (Area Code) (Telephone Number)


(2)  Have all other periodic  reports  required under Section 13 or 15(d) of the
     Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
     of 1940 during the preceding 12 months or for such shorter  period that the
     registrant was required to file such report(s) been filed? If answer is no,
     identify report(s). |X| Yes |_| No

(3)  Is it anticipated that any significant change in results of operations from
     the corresponding  period for the last fiscal year will be reflected by the
     earnings  statements  to be  included  in the  subject  report  or  portion
     thereof? X Yes |_| No

     If so, attach an explanation of the anticipated  change,  both  narratively
     and quantitatively, and, if appropriate, state the reasons why a reasonable
     estimate of the results cannot be made.

     Due to the loss of the Company's only earning asset, the Bank, as described
     in detail above and in prior filings of the Company with the Securities and
     Exchange  Commission,  as of October 31, 2009:  (i) the  Company's  primary
     assets,  excluding its  investment in the Bank and its  investments  in San
     Joaquin Bancorp Trust #1 (the "Trust"),  which  investments are expected to
     be written off completely, consisted primarily of cash and cash equivalents
     of approximately  $10 thousand and a tax refund amount,  not expected to be
     material,  currently in the  possession of the FDIC; and (ii) the Company's
     principal  liabilities are $10 million of junior  subordinated notes issued
     to the Trust,  $205  thousand in accrued and unpaid  interest on said notes
     and potential  interest rate swap and related  liabilities from a cash flow
     hedge  arrangement  with a  counterparty,  in amounts  that are still being
     determined. The Company no longer has any source for income unless the FDIC
     distributes funds from the liquidation of the Bank and no such distribution
     is expected.

     At  September  30,  2008,  the  Company  reported  consolidated  results as
     follows:  total assets of $887  million;  total  deposits of $778  million;
     total  liabilities of $831 million;  stockholders  equity of $55.7 million;
     and a net loss for the nine month period ending  September 30, 2008 of $4.3
     million. At December 31, 2008, the Company reported consolidated results as
     follows:  total assets of $936  million;  total  deposits of $767  million;
     total  liabilities of $880 million;  stockholders  equity of $56.3 million;
     and a net gain for the year of $2.5 million.  At June 30, 2009, the Company
     reported  consolidated  results as follows:  total assets of $834  million;
     total  deposits  of  $686  million;  total  liabilities  of  $797  million;
     stockholders  equity  of $37  million;  and a net loss  for the six  months
     ending June 30, 2009 of $20 million.
