                                  May 7, 1998


                             AN IMPORTANT REMINDER
                             ---------------------


Dear Shareholder:

The Annual Meeting of Shareholders of First Regional Bancorp is scheduled to be 
held on Thursday, May 21, 1998 and proxy material for this important meeting 
recently was mailed to you.  Since your vote is important and the meeting will 
be held in two short weeks, a duplicate proxy is enclosed to ensure that your 
vote is counted.

Regardless of the number of shares you own, it is important that they be 
represented and voted at the meeting.  If you have any questions or need 
assistance in voting your shares, please call me at (310) 552-1776.

                                    CAUTION
                                    -------

You should know that a dissident group of shareholders has threatened to wage a 
proxy contest at the Annual Meeting.  Led by Mark Rubin, this group may attempt 
to seize control of your Board in an 11th hour solicitation.  We will keep you 
informed of developments in this matter and urge you not to sign any card this 
group may send to you, not even as a vote of protest.

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

Since the time remaining before the meeting is short, we urge you to sign, date,
and mail the enclosed duplicate proxy today. Your interest and your
participation in the affairs of First Regional Bancorp are sincerely
appreciated.

We will continue to act in the best interest of all First Regional shareholders.

Sincerely,

/s/ Thomas E. McCullough

Thomas E. McCullough
Corporate Secretary
