     Western Bancorp (formerly named Monarch Bancorp), a California corporation,
     and Castle Creek Capital Partners Fund-I L.P., a Delaware limited 
     partnership, hereby amend and restate their Schedule 13 D relating to the 
     class of common stock, no par value, of SC Bancorp, a California 
     corporation as follows:



                             -5-



Item 3 is hereby amended and restated to read as follows:

"Item 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

      It is presently anticipated that, should any purchase of SCB Common 
Stock be made by Western pursuant to the Option Agreement described below in 
response to Item 4, or otherwise by either Western of the Fund, the source of 
any funds used in any such purchase would be the available cash, cash 
equivalents, available for sale securities and bank financing of Western or 
the Fund, as the case may be and, in the case of the Fund, capital 
contributions made by the Fund's limited partners."

      The source of funds for the purchases by the Fund on May 23, 1997 and 
May 27, 1997 described below in response to Item 4 was borrowings under the 
Fund's revolving line of credit negotiated in the ordinary course of business 
with The Northern Trust Company, an unaffiliated bank, (as defined in Section 
3(a)(6) of the Securities Exchange Act of 1934). The source of funds for the 
purchase by the Fund on June 27, 1997 described below in response to Item 4 
was capital contributions made to the Fund by its limited partners.

Item 4 is hereby amended and restated to read as follows:  

"Item 4.  PURPOSE OF TRANSACTION.

     A.   THE MERGER AGREEMENT.

     On April 29, 1997, Western and SCB entered into an Agreement and Plan of 
Reorganization (the "Merger Agreement") pursuant to which SCB agreed to merge 
with and into Western (the "Merger").  The Merger is subject to receipt of 
regulatory and shareholder approvals, as well as other closing conditions, 
and it is estimated that the merger will be consummated not later than the 
fourth quarter of 1997, subject to satisfaction of such closing conditions.

     Under the terms of the Merger, each shareholder of SCB will receive 
shares of common stock, no par value, of Western ("Western Common Stock") 
based on a purchase price of $14.25 per share of SCB Common Stock using a 
floating exchange ratio for Western Common Stock within a price range of 
$23.375 to $31.875 per share. Upon



                        -6-



     consummation of the Merger, the certificate of incorporation and bylaws
     of Western shall be the certificate of incorporation and bylaws of the
     surviving corporation, and certain directors of SCB prior to the Merger
     will become directors of Western after the Merger.

         The Merger is subject to the approval of the Board of Governors of the
     Federal Reserve Board (the "Federal Reserve Board") and California 
     authorities, the approval of the shareholders of both Western and SCB, 
     and the satisfaction of various other terms and conditions set forth in 
     the Merger Agreement.

         B.   THE OPTION.

         As an inducement and a condition to Western's entering into the Merger
     Agreement, on April 29, 1997, SCB and Western entered into a Stock Option
     Agreement (the "Option Agreement"), pursuant to which SCB granted Western
     an option (the "Option") entitling it to purchase up to 1,491,050 (or such
     lesser amount as shall constitute 19.9% of the outstanding shares of SCB 
     Common Stock on the date of exercise) fully paid and nonassessable shares 
     of SCB Common Stock at a price per share equal to $11.875 per share, 
     subject to adjustment in certain circumstances.*

         Subject to applicable law and regulatory restrictions, Western may
     exercise the Option, in whole or in part, at any time following the
     occurrence of a Purchase Event (as defined below) and prior to an 
     Exercise Termination Event (as defined below).

         As defined in the Option Agreement, "Purchase Event," means the
     occurrence of either of the following events or transactions: 

         1. The acquisition by any Person other than Western or any
     Western Subsidiary of beneficial ownership of shares of SCB Common
     Stock, other than by exercise of options, warrants or other rights (or
     in settlement or satisfaction of such rights) set forth in
     Section 4.2(a) of the SCB Disclosure Letter delivered in connection
     with the Merger Agreement (the "SCB Disclosure Letter") or as a result
     of the execution and delivery of the Shareholder Agreements referred
     to in Section 6.5 of the Merger Agreement, such that, upon the
     consummation of such acquisition, such Person would have beneficial
     ownership, in the aggregate, of 20% or more of the then outstanding
     shares of SCB Common Stock if such Person is a director or officer of
     SCB, and 25% or more of the then outstanding


   ------------------------------

*In the event of any change in the SCB Common Stock by reason of stock
dividends, split-ups, recapitalization, or the like, the type and number of
shares of SCB Common Stock subject to the Options shall be increased so that,
after such issuance and together with shares of SCB Common Stock previously
issued pursuant to the exercise of the Option, the number of shares of SCB
Common Stock subject to the Option equals 19.9% of the number of shares of SCB
Common Stock then issued and outstanding.


                            -7-



      shares of SCB Common Stock if such Person is not a director or officer of
      SCB; or


          2.  The occurrence of a Preliminary Purchase Event described in 
      Section 2(b)(i) of the Option Agreement except that the percentage 
      referred to in clause (z) shall be 20%.

     As defined in the Option Agreement, "Exercise Termination Event" means 
any one of the following events:

          1.  The Merger becoming effective;

          2.  Twelve months after the first occurrence of a Purchase Event;

          3.  Eighteen months after the termination of the Merger Agreement
     following the occurrence of a Preliminary Purchase Event (as defined
     below);

          4.  The termination of the Merger Agreement in accordance with the
     terms thereof prior to the occurrence of a Purchase Event or a Preliminary
     Purchase Event (other than a termination of the Merger Agreement by SCB
     pursuant to Section 11.1(b)(iii) or (g) thereof; or

          5.  Eighteen months after the termination of the Merger Agreement by
     SCB pursuant to 11.1(b)(iii) or (g) thereof.

     As defined in the Option Agreement, "Preliminary Purchase Event" means any
one of the following events:

          1.  SCB or any of its subsidiaries (each a "SCB Subsidiary")
      without having received Western's prior written consent, shall have
      entered into an agreement to engage in an Acquisition Transaction (as
      defined below) with any Person (the term "Person" for purposes of the
      Option Agreement having the meaning assigned thereto in Sections
      3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934 (the
      "Securities Exchange Act"), and the rules and regulations thereunder)
      other than Western or any of its subsidiaries (each a "Western
      Subsidiary") or the Board of Directors of SCB shall have recommended
      that the shareholders of SCB approve or accept any Acquisition
      Transaction with any Person other than Western or any Western
      Subsidiary.  For purposes of this Agreement, "Acquisition Transaction"
      shall mean (x) a merger or consolidation, or any similar transaction,
      involving SCB or any of SCB's subsidiaries, (y) a purchase, lease or
      other acquisition of all or substantially all of the assets of SCB or
      any subsidiary or (z) a purchase or other acquisition (including by way
      of merger, consolidation, share exchange or otherwise) of securities
      representing 10% or more of the voting power of SCB or any subsidiary,
      other than by exercise of options, warrants or other rights (or in 
      settlement or satisfaction of such rights)

                            -8-



set forth in Section 4.2(a) of the SCB Disclosure Letter, provided that the
term "Acquisition Transaction" does not include any internal merger or
consolidation involving only SCB and/or SCB Subsidiaries;

     2.  Any Person (other than Western or any Western Subsidiary) shall
have acquired Beneficial Ownership or the right to acquire Beneficial
Ownership, other than by exercise of options, warrants or other rights (or
in settlement or satisfaction of such rights) set forth in Section 4.2(a)
of the SCB Disclosure Letter, of shares of SCB Common Stock (the term
"Beneficial Ownership" for purposes of the Option Agreement having the
meaning assigned thereto in Section 13(d) of the Securities Exchange Act,
and the rules and regulations thereunder) such that, upon the consummation
of such acquisition, such Person would have Beneficial Ownership, in the
aggregate, of 10% or more of the then outstanding shares of SCB Common
Stock if such Person is a director or officer of SCB, and 25% or more of
the then outstanding shares of SCB Common Stock if such Person is not a
director or officer of SCB;

     3.  Any Person other than Western or any Western Subsidiary shall have
made a BONA FIDE proposal to SCB or its shareholders, by public
announcement or written communication that is or becomes the subject of
public disclosure, to engage in an Acquisition Transaction (including,
without limitation, any situation in which any Person other than Western or
any subsidiary of Western shall have commenced (as such term is defined in
Rule 14d-2 under the Securities Exchange Act) or shall have filed a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act"), with respect to, a tender offer or exchange offer to
purchase any shares of SCB Common Stock such that, upon consummation of
such offer, such Person would own or control 10% or more of the then
outstanding shares of SCB Common Stock (such an offer being referred to
herein as a "Tender Offer" or an "Exchange Offer", respectively)); 

     4.  After a proposal is made by a third party to SCB or its
shareholders to engage in an Acquisition Transaction, SCB shall have
breached any covenant or obligation contained in the Merger Agreement and
such breach would entitle Western to terminate the Merger Agreement or the
holders of SCB Common Stock shall not have approved the Merger Agreement at
the meeting of such shareholders held for the purpose of voting on the
Merger Agreement, such meeting shall not have been held or shall have been
canceled prior to termination of the Merger Agreement or SCB's Board of
Directors shall have withdrawn or modified in a manner adverse to Western
the recommendation of SCB's Board of Directors with respect to the Merger
Agreement;

     5.  Any Person other than Western or any Western Subsidiary, other
than in connection with a transaction to which Western has given its prior
written consent or in connection with the exercise of options, warrants or
other rights (or in settlement or satisfaction of such rights) set forth in
Section 4.2(a) of the SCB



                                 -9-



     Disclosure Letter, shall have filed an application or notice with the
     Federal Reserve Board or other governmental authority or regulatory or
     administrative agency or commission (each, a "Governmental Authority") for
     approval to engage in an Acquisition Transaction; or

          6.  The Board of Directors of SCB does not recommend that the
     shareholders of SCB approve the Merger Agreement.

     As provided in the Option Agreement, in the event that Western is entitled
and wishes to exercise the Option, it must send to SCB a written notice (the
date of which is referred to in the Option Agreement as the "Notice Date")
specifying (1) the total number of shares of SCB Common Stock which Western
intends to purchase pursuant to such exercise, (2) the aggregate purchase price
as provided herein, and (3) a period of time (not less than three business days,
nor more than 30 business days) running from the Notice Date and a place at
which the closing of such purchase shall take place; PROVIDED, HOWEVER, that if
prior notification to or approval of the Federal Reserve Board or any other
Governmental Authority is required in connection with such purchase, Western
will promptly file, and expeditiously process the required notice or application
for approval.

     Under the BHC Act, Western may not directly or indirectly acquire more than
5 percent of the outstanding shares of any class of voting Securities of SCB
without application to and prior approval from the Federal Reserve Board.

     If SCB enters into certain agreements relating to the consolidation or
merger of SCB or the sale of substantially all of its assets or deposits, SCB is
required to make proper provision so that the Option will, upon consummation of
such transaction, be converted into, or exchanged for, an option (the
"Substitute Option") in the surviving corporation in a consolidation or merger
or in the transfer of substantially all of SCB's assets or deposits, as the case
may be.  The Substitute Option will have the same terms and conditions as the
Option; PROVIDED, HOWEVER, that to the extent terms and conditions of the
Substitute Option cannot legally be identical to those of the Option, they will
in no event be less advantageous to Western.

     In certain circumstances related to the exercise of the Option, the time
period specified in the Option Agreement will be extended at the request of
Western (1) to the extent necessary to obtain all regulatory approvals and for
the expiration of all statutory waiting periods and (2) to the extent necessary
to avoid liability under Section 16(b) of the Securities Exchange Act by reason
of such exercise; PROVIDED, HOWEVER, that in no event shall any closing date
occur more than six months after the related Notice Date.

     The Option may be assigned by Western in certain circumstances, subject to
the terms and conditions described in the Option Agreement.


                                 -10-

     (a)  THE OPTION.  As a result of entry into the Option Agreement and the 
granting of the Option thereunder, pursuant to Rule 13d-3(d)(i) under the 
Exchange Act (defined above), Western is deemed to own beneficially 1,491,050 
shares of SCB Common Stock (or such lesser amount as shall constitute 19.9% 
of the outstanding shares of SCB Common Stock on the date of exercise), 
constituting approximately 19.9% of the shares of SCB Common Stock issued and 
outstanding as of April 29, 1997.  Western expressly disclaims any beneficial 
ownership of the 1,491,050 shares of SCB Common Stock which are obtainable by 
Western upon exercise of the Option, because the Option is exercisable only 
in the circumstances set forth in the Option Agreement, which is described in 
Item 4 hereof, none of which has occurred as of the date hereof and only then 
with regulatory approval (if, as a consequence, Western would own more than 
5% of the outstanding shares of SCB Common Stock).  

     PURCHASES OF SCB COMMON STOCK.  Western and the Fund own 5,700 and 
337,500 shares of SCB Common Stock, respectively, with full voting and 
dispositive powers.

     (b)  If Western were to exercise the Option, it would have sole power to
vote and, subject to the terms of the Option Agreement, sole power to direct the
disposition of, the shares of SCB Common Stock covered thereby.

     (c)  On May 27, 1997, Matthew P. Wagner, President of Western, purchased 
3,000 shares of SCB Common Stock, at $12.50 per share, in an open market 
transaction. On May 22, 1997, Arnold C. Hahn, Chief Financial Officer of 
Western, purchased 5,000 shares of SCB Common Stock, at $12.44 per share, in 
an open market transaction. On May 16, 1997, Hugh S. Smith, Jr. purchased 
5,000 shares of SCB Common Stock, at $11.86 per share, in an open market 
transaction. Other than as set forth herein, none of Western or to the best 
knowledge of Western, any of its directors or executive officers or any 
persons controlling Western listed on Annex A hereto has effected any 
transaction in shares of SCB Common Stock during the past 60 days.

     (d)  Not applicable.

     (e)  Not applicable."
