Item 4.  Description of Securities.

Authorized Shares - General

         The authorized capital stock of the Corporation  consists of 20,000,000
shares of common stock, no par value, and 10,000,000  shares of preferred stock.
Each share of common stock has the same rights,  preferences  and  privileges as
every  other  share of common  stock.  The  common  stock has no  conversion  or
redemption rights or sinking funds  provisions.  Holders of the common stock are
entitled to participate in such dividends as may be declared by the Board out of
funds legally available  therefor and, in the event of liquidation,  dissolution
or winding up of the  Corporation,  are entitled to share  ratably in all assets
remaining  after  the  payment  of  liabilities  and the  payment  to  preferred
shareholders.  The  Corporation's  common  shares are not subject to  assessment
under the applicable law.

         The transfer agent and registrar for the Corporation's common stock is
U.S. Stock Transfer Corporation of Glendale, California.

Voting Rights

         Each  share of  common  stock  is  entitled  to one  vote on any  issue
requiring  a vote and  holders  of the common  stock have the right to  cumulate
votes in elections of directors, as described below.

         California law provides that a shareholder of a California corporation,
or his proxy,  may cumulate  votes in  elections  for  directors,  that is, each
shareholder  has a number of votes  equal to the number of shares  owned by him,
multiplied  by the number of directors to be elected,  and he may cumulate  such
votes for a single  candidate or distribute  such votes among as many candidates
as he deems  appropriate.  However,  a shareholder may cumulate votes only for a
candidate or  candidates  whose names have been  properly  placed in  nomination
prior to the voting and only if the shareholder has given notice at the meeting,
prior  to the  voting,  of his  intention  to  cumulate  his  votes.  If any one
shareholder  has given such notice,  all  shareholders  may  cumulate  votes for
candidates in nomination.

         Except as set forth  below with  respect  to the  voting  rights of the
preferred shares,  holders of the Corporation's  common stock have the exclusive
right to notice of  shareholders'  meetings and the  exclusive  right to vote at
shareholders'  meetings,  and the Corporation's Articles of Incorporation may be
amended by the affirmative vote of the holders of a majority of the common stock
of the  Corporation.  The  approval  of the holders of  two-thirds  (2/3) of the
Series A  preferred  shares is  required  for the  Corporation  to do any of the
following:

         1.  Amend or repeal  any  provision  of, or add any  provision  to, the
Corporation's  Articles of  Incorporation,  if such action would alter or change
the rights, preferences,  privileges, or powers of, or the restrictions provided
for the  benefit  of, any Series A Shares,  so as to affect such Series A Shares
adversely; or

         2.       Increase the authorized number of the Series A Shares; or

         3. Create any new class of shares having preferences over or being on a
parity with the Series A shares as to dividends or assets, unless the purpose of
creation of such class is, and the  proceeds to be derived from the sale and the
issuance  thereof are to be used for, the retirement of all Series A Shares then
outstanding; or

         4.       Purchase any common stock; or

         5. Sell, lease, exchange, transfer, convey, or otherwise dispose of, or
create  or incur  any  mortgage,  lien,  charge or  encumbrance  on or  security
interest in or pledge of, or sell and leaseback, all or substantially all of the
property or business of the Corporation.

Nominations of Directors

         The  Corporation's  Bylaws  provide that  nominations  for directors by
shareholders  may be made,  provided  that  certain  informational  requirements
concerning  the  identities of the  nominating  shareholder  and the nominee are
complied with in advance of the meeting. The written nomination must include the
following  information:  (a) the name and address of each proposed nominee,  (b)
the principal  occupation of each proposed nominee,  (c) the number of shares of
the  Corporation  owned by each  proposed  nominee,  (d) the name and  residence
address of the  nominating  shareholder,  and (e) the number of shares of voting
stock of the corporation owned by the nominating shareholder.  This provision is
intended  to provide  advance  notice to  management  of any effort to effect an
election contest or a change in control of the Board of Directors.

Dividends

         The dividend  policy of the Corporation is subject to the discretion of
the Board of Directors and depends upon a number of factors, including earnings,
financial condition,  cash needs and general business  conditions.  In addition,
the Board of Directors may declare dividends only out of funds legally available
therefor.

         The California General  Corporation Law provides that a corporation may
make a  distribution  if its retained  earnings at least equal the amount of the
proposed  distribution.  In the event that sufficient  retained earnings are not
available for the proposed  distribution,  a corporation may nevertheless make a
distribution if,  immediately after giving effect to the proposed  distribution,
it meets both the  "quantitative  solvency" and the  "liquidity"  tests,  as set
forth in the law. In general,  the quantitative  solvency test requires that the
sum of the assets of the corporation equal at least 1-1/4 times its liabilities.
The liquidity test generally  requires that a corporation have current assets at
least  equal to  current  liabilities  or, if the  average  of  earnings  of the
corporation  before  taxes on income and  before  interest  expense  for the two
preceding  fiscal years was less than the average of the interest expense of the
corporation  for such  fiscal  years,  current  assets must equal at least 1-1/4
times current liabilities.

         The Corporation's  primary source of income is the receipt of dividends
from its subsidiary, the Bank. The Bank's ability to pay dividends is subject to
the  restrictions of the California  Financial Code,  which restricts the amount
available  for cash  dividends  to the lesser of the  retained  earnings  or the
Bank's net income for its last three  fiscal  years (less any  distributions  to
shareholders  made during such  period).  Where the above test is not met,  cash
dividends  may  still  be  paid,  with  the  prior  approval  of the  California
Commissioner of Financial Institutions,  in an amount not exceeding the greatest
of (1) the retained earnings of the bank; (2) the net income of the bank for its
last fiscal year; or (3) the net income of the bank for its current fiscal year.
On December 31, 1997, the Bank was legally able to pay dividends.

Issuance of Additional Shares

         The Corporation has authorized  capital stock  consisting of 20,000,000
common shares and 10,000,000  preferred shares. Such shares have been authorized
in order that the Corporation may, in the future,  raise additional  capital for
growth  purposes or to respond to  regulatory  capital  requirements.  While the
Corporation  has no present  plans to do so, such shares may be offered  without
the  approval  of the  then  shareholders  of the  Corporation.  Authorized  but
unissued  shares are sometimes used in connection  with responses to attempts to
acquire  control of a corporation.  Although the Board of Directors is not aware
of and does not  anticipate any attempt to acquire  control of the  Corporation,
authorized  but  unissued  shares  can be used to respond  to such  attempts  by
selling  shares  to a party  who  supports  existing  management  or in order to
increase the number of shares outstanding,  which would both increase the amount
of consideration  necessary to effect a change in control of the Corporation and
dilute the  percentage  ownership  and  voting  rights of an  acquiror  that had
already acquired some portion of the Corporation's outstanding stock.

Preemptive Rights

         Holders of the common stock of the  Corporation do not have  preemptive
rights,  that is,  any  rights  to  subscribe  for  additional  shares  or other
securities  which the  Corporation  may issue in the future.  Therefore,  future
shares of the  Corporation's  common stock or other securities may be offered to
the investing public or to shareholders,  at the discretion of the Corporation's
Board of Directors.

Item 5.  Interests of Named Experts and Counsel.

Not applicable.

Item 6.  Indemnification of Directors and Officers.

         Article FOUR of the  Registrant's  Articles of  Incorporation  provides
that  the  Registrant  is  authorized  to  indemnify  its  directors,  officers,
employees and other agents as follows:

         "FOUR:   (a) The liability of the directors of the corporation for
monetary damages shall be eliminated to the fullest extent permissible under
California law.

         "(b) This  corporation  is  authorized  to provide  indemnification  of
agents (as  defined in  Section  317 of the  Corporations  Code)  through  bylaw
provisions,  agreements with the agents,  vote of shareholders or  disinterested
directors or otherwise, in excess of the indemnification  otherwise permitted by
Section 317 of the California  Corporations  Code, subject to the limits of such
excess  indemnification set forth in Section 204 of the California  Corporations
Code with  respect to  actions  for  breach of duty to the  corporation  and its
shareholders."

         Article VI of the Registrant's  Bylaws provides for  indemnification of
directors, officers, employees and other "agents" of the corporation as follows:

                                   "ARTICLE VI

                                "Indemnification

                  "Section 1.  Definitions.  For the  purposes of this  Article,
"agent"  includes  any person who is or was a Director,  officer,  employee,  or
other  agent of the  corporation,  or is or was  serving  at the  request of the
corporation as a Director,  officer,  employee,  or agent of another  foreign or
domestic corporation, partnership, joint venture, trust, or other enterprise, or
was a Director, officer, employee, or agent of a foreign or domestic corporation
which was a predecessor  corporation of the corporation or of another enterprise
at the  request  of such  predecessor  corporation;  "proceeding"  includes  any
threatened, pending, or completed action or proceeding, whether civil, criminal,
administrative  or  investigative;  and "expenses"  includes without  limitation
attorneys'  fees and any  expenses of  establishing  a right to  indemnification
pursuant to law.


                  "Section 2. Extent of Indemnification.  The corporation shall,
to the maximum  extent  permitted by the  California  General  Corporation  Law,
advance  expenses  to  and  indemnify  each  of  its  agents  against  expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with any proceeding  arising by reason of the fact any such person
is or was an agent of the corporation.

                  "Section 3.  Insurance.  The  corporation  shall have power to
purchase  and  maintain  insurance  on behalf  of any  agent of the  corporation
against any liability asserted against or incurred by the agent in such capacity
or arising  out of the  agent's  status as such  whether or not the  corporation
would have the power to indemnify  the agent  against such  liability  under the
provisions of this Article."

         The provisions of the California  General  Corporation  Law relating to
indemnification  of  directors,  officers,  employees  and  other  agents  of  a
corporation,  as  presently  in effect,  are set forth in Sections  204 and 317,
copies of which are included in this Registration Statement as Exhibit 99.

         The Registrant  maintains  directors' and officers' liability insurance
which covers certain  liabilities  and expenses of officers and directors of the
Registrant and covers the Registrant for  reimbursement of payments to directors
and officers in respect of such liabilities and expenses.

Item 9.  Undertakings.

         The undersigned  registrant  hereby  undertakes (1) to file, during any
period in which it offers or sells  securities,  a  post-effective  amendment to
this  Registration  Statement  to include  any  additional  or changed  material
information  on  the  plan  of  distribution;  (2)  that,  for  the  purpose  of
determining   any  liability  under  the  Securities  Act  of  1933,  each  such
post-effective  amendment  shall be  deemed to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering  thereof;  and
(3) to remove from  registration by means of a  post-effective  amendment any of
the securities  being  registered which remain unsold at the termination of this
offering.

         The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of 1934) that is  incorporated  by  reference  in this
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the registrant of expenses
incurred or paid by a director,  officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.






                                   SIGNATURES


Pursuant to the  requirements  of the  Securities  Act of 1933,  the  Registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-8 and has  duly  caused  this  registration
statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Redwood City, State of California, on March 9, 1998.
