SHAREHOLDER AGREEMENT


            Shareholder Agreement (the "Agreement"), dated as of April 29, 1997,
by and between (i) Harold A. Beisswenger, a director and shareholder (the
"Shareholder") of SC Bancorp, a California corporation (the "Company"), and (ii)
Monarch Bancorp, a California corporation ("Monarch").  All terms used herein
and not defined herein shall have the meaning assigned thereto in the Merger
Agreement (defined below).

            Whereas, the Company and Monarch have entered into an Agreement and
Plan of Reorganization, dated the date hereof (the "Merger Agreement"),
providing for the business combination transaction contemplated therein in which
the Company will merge with and into Monarch pursuant to the terms and
conditions of the Merger Agreement (the "Merger") and Monarch will pay
consideration to the Company's shareholders in the form of Monarch Common Stock;

            Whereas, the Shareholder has agreed to furnish Monarch (within 10
days after the date hereof) a list setting forth the number of shares of Company
Common Stock owned by Shareholder (such shares, together with all shares of
Company Common Stock subsequently acquired by the Shareholder during the term of
this Agreement, being referred to as the "Shares"); and

            Whereas, in order to induce Monarch to enter into the Merger
Agreement and in consideration of the substantial expenses incurred and to be
incurred by Monarch in connection therewith, the Shareholder has agreed to enter
into and perform this Agreement.

            Now, therefore, for good and valuable consideration, the receipt,
sufficiency and adequacy of which are hereby acknowledged, the parties hereto
agree as follows:

            1.  AGREEMENT TO VOTE SHARES.  Shareholder shall vote or cause to be
voted, or execute a written consent with respect to, the Shares (a) in favor of
adoption and approval of the Merger Agreement and the Merger and all
transactions relating thereto at every meeting of the shareholders of the
Company at which such matters are considered and at every adjournment thereof
and in connection with every proposal to take action by written consent with
respect thereto, and (b) against any other Acquisition Proposal at every meeting
of the shareholders of the Company at which such matters are considered and at
every adjournment thereof and in connection with every proposal to take action
by written consent with respect thereto.

            2.  NO VOTING TRUSTS.  Shareholder agrees that Shareholder will not,
nor will Shareholder permit any entity under Shareholder's control to, deposit
any Shares in a voting trust or subject the Shares to any agreement, arrangement
or understanding with respect to the voting of the Shares inconsistent with this
Agreement.

            3.  LIMITATION ON SALES.  During the term of this Agreement,
Shareholder agrees not to sell, assign, transfer or dispose of any of the
Shares.



            4.  REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER. Shareholder
represents and warrants to and agrees with Monarch as follows:

              a.   CAPACITY.  Shareholder has all requisite capacity and
         authority to enter into and perform his or her obligations under this
         Agreement.

              b.   BINDING AGREEMENT.  This Agreement constitutes the valid and
         legally binding obligation of Shareholder, subject to bankruptcy,
         insolvency, fraudulent transfer, reorganization, moratorium and
         similar laws of general applicability relating to or affecting
         creditors' rights and to general equity principles.

              c.   NON-CONTRAVENTION.  The execution and delivery of this
         Agreement by Shareholder does not, and the performance by Shareholder
         of his or her obligations hereunder and the consummation by
         Shareholder of the transactions contemplated hereby will not, violate
         or conflict with, or constitute a default under, any agreement,
         instrument, contract or other obligation or any order, arbitration
         award, judgment or decree to which Shareholder is a party or by which
         Shareholder is bound, or any statute, rule or regulation to which
         Shareholder is subject or, in the event that Shareholder is a
         corporation, partnership, trust or other entity, any charter, bylaw or
         other organizational document of the Shareholder.

              d.   OWNERSHIP OF SHARES.  Shareholder has good title to all of
         the Shares as of the date hereof, and the Shares are so owned free and
         clear of any liens, security interests, charges or other encumbrances.

            5.  COMPETITION.  Neither Shareholder nor any corporation,
partnership, trust or other entity controlled by Shareholder shall:

              (a)  at any time within a three-year period immediately following
         the Effective Time, engage in, be employed by, acquire an equity
         interest in or start, or otherwise provide any assistance to, directly
         or indirectly, any business which provides banking services,
         including, but not limited to, deposit and operational services,
         loans, trust services, escrow services and electronic banking services
         (the "Banking Business"), in the counties of Los Angeles, Orange and
         San Diego in the State of California so long as Monarch or its assigns
         remain engaged in any Banking Businesses;

              (b)  at any time following the Effective Time, disclose
         confidential information regarding the Company or SC Bank to any third
         parties, except as required by law, regulation, a court order, in the
         defense of litigation for which such shareholder, the Company or SC
         Bank may be liable, or in any actions relating to this Agreement or
         the Merger Agreement and the transactions contemplated hereby or
         thereby; and


                                          2



              (c)  solicit, directly or indirectly, on its own behalf or on
         behalf of any other person or entity, management personnel employed by
         Monarch immediately after the Effective Time for employment with any
         other business;

PROVIDED, HOWEVER, that with respect to any of the matters covered in this
Section 5, to the extent that any restriction set forth in this Section 5 is
adjudicated to be invalid or unenforceable in any jurisdiction, the court making
such determination shall have the power to limit, construe or reduce the
duration, scope, activity or area of such provision to the extent necessary to
render such provision enforceable to the maximum extent permitted by applicable
law, such limited form to apply only with respect to the operation of such
provision in the particular jurisdiction in which such adjudication is made, and
PROVIDED, FURTHER, that nothing herein shall prohibit Shareholder from ownership
of an equity interest in any Banking Business to the extent that such ownership
is of less than five percent (5%) of the outstanding shares of capital stock of
any Banking Business with one or more classes of its capital stock listed on a
national securities exchange or actively traded on the over-the-counter market.

            6.  SPECIFIC PERFORMANCE AND REMEDIES.  Shareholder acknowledges
that it will be impossible to measure in money the damage to Monarch if
Shareholder fails to comply with the obligations imposed by this Agreement and
that, in the event of any such failure, Monarch will not have an adequate remedy
at law or in damages.  Accordingly, Shareholder agrees that injunctive relief or
other equitable remedy, in addition to remedies at law or in damages, is the
appropriate remedy for any such failure and will not oppose the granting of such
relief on the basis that Monarch has an adequate remedy at law.  Shareholder
agrees that it will not seek, and agrees to waive any requirement for, the
securing or posting of a bond in connection with Monarch's seeking or obtaining
such equitable relief.  In addition to all other rights or remedies which
Monarch may have against Shareholder in the event of a default in Shareholder's
performance of Shareholder's obligations under this Agreement, Shareholder shall
be liable to Monarch for all litigation costs and attorneys' fees incurred by
Monarch in connection with the enforcement of any of its rights or remedies
against Shareholder.  In addition, after discussing the matter with Shareholder,
Monarch shall have the right to inform any third party that Monarch reasonably
believes to be, or to be contemplating, participating with Shareholder or
receiving from Shareholder assistance in violation of this Agreement, of the
terms of this Agreement and of the rights of Monarch hereunder, and that
participation by any such persons with Shareholder in activities in violation of
Shareholder's agreement with Monarch set forth in this Agreement may give rise
to claims by Monarch against such third party.

            7.  TERM OF AGREEMENT; TERMINATION.  The term of this Agreement
shall commence on the date hereof and such term and this Agreement shall
terminate upon the earlier to occur of (i) the Effective Time, and (ii) the date
on which the Merger Agreement is terminated in accordance with its terms.  Upon
such termination, no party shall have any further obligations or liabilities
hereunder; PROVIDED, HOWEVER, such termination shall not relieve any party from
liability for any breach of this Agreement prior to such termination.

supplemented or modified, and no provisions hereof may be modified or waived,
