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




                                 REVOLVING NOTE
                                 --------------
                                                           Indianapolis, Indiana
                                                                  April 21, 2005


     FOR VALUE RECEIVED, the undersigned,  White River Capital, Inc., an Indiana
corporation  (the  "Borrower"),  HEREBY  UNCONDITIONALLY  PROMISES TO PAY to the
order of  Castle  Creek  Capital  Partners  Fund  IIa,  LP (the  "Lender"),  the
principal sum of  $84,364.20,  or, if less,  the aggregate  unpaid amount of all
advances made hereunder by the Lender to the Borrower on August 16, 2005, or, if
earlier, the date three business days following consummation of the subscription
offering  described  in  Borrower's   registration   statement  filed  with  the
Securities and Exchange Commission (Reg. No. 333-123909) ("Due Date").

     Lender may make advances  hereunder upon the request of Borrower  solely to
fund Borrower's operating expenses,  such as employee  compensation,  and not to
fund  Transaction  Expenses as defined in the Warrant  Issuance  Agreement dated
March 9, 2005,  among Borrower,  Lender,  Castle Creek Capital LLC, Castle Creek
Capital  Partners Fund IIb, LP and Union  Acceptance  Corporation.  The Borrower
promises to pay interest on the unpaid  principal amount  outstanding  hereunder
from time to time from the date such  principal  amount is  advanced  until such
principal  amount is paid in full at a rate of 10% per  annum,  based on 360 day
year consisting of twelve 30-day months.  Accrued and unpaid interest is payable
on the Due Date.

     Both  principal  and  interest  are  payable in lawful  money of the United
States of America to such domestic  account as the Lender may designate.  At the
time of each  advance,  and upon each payment or prepayment of principal of each
advance,  the Lender  shall make a notation  either on a schedule to be attached
hereto, or in Lender's own books and records, in each case specifying the amount
of such advance, or the amount of principal paid or prepaid with respect to such
advance, as the case may be; provided that the failure of the Lender to make any
such  recordation or notation  shall not affect the  obligations of the Borrower
hereunder.

     Borrower may make prepayments of the principal hereof together with accrued
interest prior to the maturity hereof, without penalty or premium.

     Demand, presentment,  protest and notice of nonpayment are hereby waived by
the Borrower.  All amounts  payable under the terms of this Revolving Note shall
be payable with expenses of collection,  including  attorney's fees, and without
relief from valuation and appraisement laws.

     This Revolving Note shall be governed by, interpreted and enforced, and the
rights and liabilities of the parties hereto determined,  in accordance with the
internal laws (without  regard to the conflicts of law  provisions) of the State
of Indiana.
