     1.        FOR VALUE RECEIVED the undersigned PRIME FINANCIAL CORPORATION,
an Oklahoma corporation, promises to pay to the order of BANK IV OKLAHOMA,
N.A., a national banking association at its offices at 515 South Boulder,
Tulsa, Oklahoma 74103 ("Payee") the principal amount of this Note or such

on the unpaid balance of such amount at the rate hereinafter set forth.   This
Promissory Note is issued pursuant to that certain Loan Agreement dated March

Loan Agreement as amended by the Modification Agreement is hereinafter
referred to as the "Agreement"), by and between Payee, as Lender, and Maker,
as Borrower, and is subject to the provisions therein set forth.  The
obligations represented by this Note are secured by the Loan Documents
described in the Agreement.

     2.        Principal Amount. THIRTY-FIVE MILLION DOLLARS (%35,000,000.00).

     3.        Payments. All accrued interest on the unpaid balance of this

Rate" set forth in the Agreement.

     6.        Prepayment Penalties. This Note may be prepaid, in whole or in
part, at any time, without premium or penalty.

     7.        Default. If any Event of Default occurs under the Agreement, as
defined therein, the holder hereof may, without notice and without presentment
or demand for payment, declare all of the unpaid balance hereof to be
immediately due and payable. Such right of acceleration is cumulative and
in addition to any other right or rights of acceleration under the Agreement
and any other writing now or hereafter evidencing or securing payment of any
of the indebtedness evidenced hereby.

     8.   Costs and Attorneys' Fees. If this Note is placed in the hands of an
attorney for collection, or suit is brought on same, or the same is collected
through bankruptcy or other judicial proceeding, or Payee is required to
defend the priority of the security, then the undersigned shall pay all of
Payee's reasonable costs and expenses, including but not limited to a
reasonable amount as attorneys' fees.

     9.   Waivers. Maker and any party which may be or become liable for the
payment of any sums of money payable on this Note (including any surety,
endorser or guarantor) severally waive presentment and demand for payment,
protest, notice of protest and nonpayment, and notice of the intention to
accelerate, and agree that their liability on this Note shall not be affected
by any renewal or extension in the time of payment hereof, by any indulgences
or by any release or change in any security for the payment of this Note,
regardless of the number of such renewals, extensions, indulgences, releases
or changes.

     10.  Right of Offset. Any indebtedness due from holder hereof to the
undersigned or any party hereto including, but without limitation, any
deposits or credit balances due from holder, is pledged to secure payment of
this Note and any other obligation to holder of the undersigned or any party
hereto, and may at any time while the whole or any part of such obligation
remains unpaid either before or after maturity hereof, be appropriated, held
or applied toward the payment of this Note or any other obligation to holder
of the undersigned or any party hereto.

County, Oklahoma and shall be governed by and construed according to the laws
of the State of Oklahoma 

     12.  Renewal.   This Extended, Modified and Renewed Promissory Note
extends, modifies, renews and replaces (but does not extinguish the
indebtedness represented by) that certain Promissory Note dated March 30, 1994
by Maker in favor of Payee in the principal amount of %25,000,000.00.
