            such change in the quality of a loan shall be included in

            reflected in the calculation of the Tangible Book Value
            of the Bank at the Effective Time, or if such change is
            less than $25,000;

                    (ix)     to the extent not otherwise reflected in
            the calculations of the Tangible Book Value of the Bank,
            the amount, either positive (if the aggregate fair market
            value exceeds book value) or negative (if the aggregate
            fair market value is less than book value), by which the
            aggregate fair market value of the Bank's Securities
            Portfolio at the Effective Time differs from the
            aggregate book value of the Securities Portfolio on such
            date;

                    (x)      $11,000,000, with respect to the Bank's
            deposit balances;

                    (xi)     $10,500,000, with respect to the Bank's
            net operating loss carryforward at the Effective Time; 

                    (xii)    the difference, positive (in the case of
            a rise in the yield curve) or negative (in the case of a
            decline in the yield curve), between the aggregate book
            value of all of the Bank's Time Deposits at the Effective
            Time and the aggregate value of such deposits after
            repricing them to the Treasury yield curve at the
            Effective Time; and

                    (xiii)   $1,400,000, representing the aggregate
            premiums attributable to the Sayre, Clinton, Thomas, and
            Beaver branches of the Bank.

            
            2.3.    Additional Adjustments to Purchase Price. (a) The
percentages specified in subparagraphs (iii) and (iv) of Section
2.2 were calculated using the following yields and spreads as of
August 31, 1993:

                                              15 year        30 year
            Bank's average portfolio yield    7.44%          8.79%
            FNMA required 30-day yield        6.19%          6.66%
            Spread                            1.25%          2.13%

If, at the Effective Time, either of such spreads has fluctuated by
more than 0.25%, the applicable percentages in subparagraphs (iii)
and (iv) of Section 2.2(a) will be adjusted up (if the spread has
widened) or down (if the spread has narrowed) by 1/4 of one percent
for each full 1/8 of one percent change in the spread, in the case
of loans with an original term of 15 years or less, and by 3/8 of
one percent for each full 1/8 of one percent change in the spread,
in the case of loans with an original term of more than 15 but not
more than 30 years.


            (b)     The amount of the Purchase Price will be increased
by the aggregate amount, if any, the Tangible Book Value of the
Bank at the Effective Time has been reduced by any restructuring
charge or charges that the Bank shall have recorded on its books as
the result of the anticipated effects of the Purchase, none of
which the Bank shall be obligated to take, and all of which shall
have been approved in advance in writing by Fourth to the extent
permitted by Law.


            2.4.    Post-Closing Adjustments.  (a) Unless otherwise
specifically provided herein, each component of the Purchase Price
shall be calculated as of the Effective Time; provided, however,
that if any element of the Purchase Price cannot be calculated
accurately as of the Effective Time, such items shall be calculated
as of the end of the month preceding the Effective Time.  Any
element of the Purchase Price so calculated shall be adjusted to
reflect the accurate amount as of the Effective Time and Sellers
and Fourth agree to enter into mutually  agreeable arrangements for
the final adjustment and the payment or repayment of the net amount
thereof with interest from the Effective Time at four percent per
year within five business days after Sellers deliver to Fourth a
written statement setting forth in reasonable detail all proposed
price adjustments and the basis of calculating each.


            (b)     Upon completion of the 1994 consolidated corporate
income tax return of LSB, LSB shall notify Fourth of the amount of
the final net operating loss carryforward of the Bank at the
Effective Time.  To the extent any payment shall be owing to Fourth
pursuant to the formula set forth in clause (ii) and the second
sentence of Section 7.5(a) and regardless of whether Sellers
exercise the option referred to in Section 7.5(c), LSB shall make
such payment to Fourth no later than the due date of LSB's 1994
consolidated federal income tax return (including extensions). 



            2.5.    Closing.  The Closing shall take place at the
offices of Foulston & Siefkin, 700 Fourth Financial Center,
Wichita, Kansas, at 10:00 a.m., or at such other time or place as
the parties may agree, on a date selected by Fourth upon giving
reasonable notice to Sellers, which, unless otherwise agreed, shall
be on the 15th day (or the closest Friday if the 15th is not a
Friday) of the month in which the final Regulatory Approval is
obtained and in which all required waiting periods expire if such
earliest legal closing date is during the first 15 days of the
month and on the last business day of the month if the earliest
legal  closing  date  occurs  after the 15th day of a month.  The 
parties agree to exert their best efforts to cause the Closing to
occur on or before June 30, 1994.


            2.6.    Closing Deliveries.  At the Closing:


                    a.       Sellers shall deliver to Fourth:

                    the Shares, endorsed for transfer to Fourth, free

                    interests, claims, and equities whatsoever; 
            
                             (ii)    such other documents including

                    Agreement or reasonably requested by Fourth; and

                             (iii)   the opinion of Housley Goldberg &
                    Kantarian, P.C., counsel to Sellers and the Bank,
                    substantially in the form of Exhibit "A" hereto.


                    b.       Fourth shall deliver to Sellers:

                    total amount of the Purchase Price;

                             (ii)    such documents including officers'
                    certificates as may be required by this Agreement
                    or reasonably requested by Sellers; and

                             (iii)   the opinion of Foulston & Siefkin,
                    counsel to Fourth, substantially in the form of
                    Exhibit "B" hereto.


                    c.       BANK IV and Northwest Tower Limited
            Partnership shall execute and deliver a real estate lease
            substantially in the form of Exhibit "C" hereto pursuant
            to which Bank will lease from Northeast Tower Limited
            Partnership certain first-floor and other space in the
            Equity Tower in Oklahoma City for a ten-year term, with
            renewal options and options to rent additional space in
            such building.


                    Contemporaneously with the Purchase, the Bank
            shall be merged into BANK IV pursuant to the Bank Merger
            Agreement. 


            2.7.    Option to Acquire Certain Loans.   Sellers shall
have the option, but not the obligation, to acquire any loan owned
by the Bank that has been charged off or written down for a
purchase price equal to the net book value of each loan that has
been written down and for a purchase price of $1.00 in the case of
each loan that has been charged off.  


            2.8.    Retained Assets, Retained Corporations, and
Certain Loans.  Subject to all of the closing conditions set forth
in Sections 5.1 and 5.2 having occurred and continuing in effect,
Sellers shall purchase the Retained Assets from the Bank at the
Effective Time for the aggregate book value thereof as of the
Effective Time (or $1.00 in the case of each loan that has been
charged off), and Sellers shall purchase all of the capital stock
of all of the Retained Corporations from the Bank not later than
the business day immediately preceding the Effective Time for the
aggregate book value thereof as of such date.  Each such purchase
shall be effected by the payment to the Bank of immediately
available funds.  All sales by the Bank of OREO Properties shall be
pursuant to a real estate contract substantially in the form of
Exhibit "D" hereto.



                                 ARTICLE III

                          AGREEMENTS OF THE PARTIES


            3.1.    Agreements of Fourth.
            
                    a.     Prior to the Effective Time, Fourth,
            separately and with Sellers, shall use its best efforts
            in good faith to take or cause to be taken as promptly as
            practicable all such steps as shall be necessary to
            obtain all of the Required Approvals.


                    b.     Fourth shall promptly prepare and file all
            applications necessary to obtain the Required Approvals
            and shall afford Sellers at least four days' opportunity
            to review and comment upon the drafts of such
            applications prior to the filing thereof.


                    c.     Fourth shall observe the confidentiality
            obligations set forth in Section 3.2.c, below.


                    d.     Fourth shall consult with Sellers prior to
            issuing any press release or other planned public
            statement regarding the subject matter of this Agreement
            or the termination thereof as to the contents of such
            press release or statement.


                    e.     Fourth agrees to take such action as may be
            necessary to cause BANK IV to be well capitalized upon
            the consummation of the transactions contemplated by this
            Agreement at and immediately following the Effective
            Time.


                    f.     Fourth agrees to provide such information as
            LSB may reasonably request in connection with the
            preparation of material for the conduct of a meeting of
            LSB's stockholders to approve this Agreement, and such
            information furnished by Fourth will not contain any
            untrue statement of a material fact or omit to state a
            material fact required to be stated therein or necessary
            in order to make the statements therein, in light of the
            circumstances under which they were made, not misleading.


                    g.     Following the Closing, in the event Sellers
            or any of their Subsidiaries, officers, directors, or
            affiliates shall be called upon to provide an indemnity
            pursuant to the provisions of this Agreement, or should
            otherwise be called upon to take or defend against legal
            action with respect to matters occurring prior to the
            Effective Time, Fourth shall permit Sellers to examine
            (subject to reasonable limitations) the former records of
            the Bank or the Corporations.


                    h.  BANK IV shall reimburse LSB for all out-of-
            pocket  COBRA liabilities incurred by LSB with respect to
            employees of the Bank at the Effective Time who are
            terminated after the Effective Time by BANK IV to the
            extent not paid or reimbursed by re-insurance or stop
            loss coverage; provided, however that such reimbursement
            shall be net of all COBRA premiums paid by such employees
            after the Effective Time and net of the aggregate amount
            of all Bank employee forfeitures under the Bank's
            cafeteria plan.

                    this Agreement, enter into any transaction or
                    take any action which would, if effected prior to
                    the Effective Time, constitute a material breach
                    of any of the representations, warranties, or
                    covenants contained in this Agreement.


                    b.   Except as otherwise provided in this
            Agreement, prior to the Effective Time, each Seller shall
            use its reasonable best efforts to cause each of the
            Corporations to conduct its respective business in the
            ordinary and usual course as heretofore conducted and to

            good faith and has established reasonable reserves
            therefor, to pay when required to be paid all material
            taxes indicated by tax returns so filed or otherwise
            lawfully levied or assessed upon it or any of its
            properties and to withhold or collect and pay to the
            proper governmental authorities or hold in separate bank
            accounts for such payment all taxes and other assessments
            which it believes in good faith to be required by law to
            be so withheld or collected.


                    c.   Prior to the Effective Time, Sellers shall
            cause the Corporations, to the extent permitted by Law,
            to give Fourth and its counsel and accountants full
            access, during normal business hours and upon reasonable
            notice, to their respective properties, books, and
            records, and to furnish Fourth during such period with
            all such information concerning their affairs as Fourth
            may reasonably request.  Except for matters expressly
            disclosed in the Disclosure Statement, the availability
            or actual delivery of information about the Corporations
            to Fourth shall not affect the covenants,
            representations, and warranties of Sellers contained in
            this Agreement.  Except for information disclosed in the
            course of obtaining  Required Approvals, Fourth shall
            treat as confidential all confidential information
            disclosed to it by Sellers or the Corporations in the
            same manner as Fourth treats similar confidential
            information of its own and, if this Agreement is
            terminated, Fourth shall continue to treat all such
            confidential information obtained through such disclosure
            and not otherwise known to Fourth or already in the
            public domain, as confidential and shall return such
            documents theretofore delivered by Sellers to Fourth as
            Sellers shall request.
 

                    d.   Sellers shall cause the Corporations,
            separately and jointly with each other and with Fourth,
            to each use reasonable efforts in good faith to take or
            cause to be taken as promptly as practicable all such
            steps as shall be necessary to obtain all Required
            Approvals as promptly as practicable.


                    e.   Sellers agree not to sell, pledge, encumber,
            or otherwise hypothecate or transfer any shares of Bank
            Stock prior to the Effective Time.


                    f.   At the Closing, BANK IV, as lessee, and 
            Northwest Tower Limited Partnership, as lessor, shall
            execute and deliver a real estate lease substantially in
            the form of Exhibit "C," to this Agreement.  No party
            hereto shall be liable to any other party if such lessor
            fails to execute such lease.

                    g.   Sellers agree to cause the Corporations to
            cooperate with Fourth in Fourth's efforts to obtain
            current title evidence or insurance, environmental
            assessment reports, and surveys on such of the
            Corporations' real properties as Fourth may desire.

                    h.   Sellers will take, and will cause the Bank to
            take, all such corporate action as may be required to
            authorize, execute, and perform the Bank Merger
            Agreement.
            

                    i.   LSB agrees:  

                         (1)   To file all required federal, state,
                    and local income tax returns in a timely manner
                    for 1993 and 1994 or obtain appropriate
                    extensions for such filings and to pay, when due,
                    all income taxes due for such periods;

                         (2)   To give Fourth written notice promptly
                    of any issues raised by any taxing authorities
                    which might reasonably result in an increase in
                    the income tax liabilities of the Bank for any
                    period in which it is or was a member of the
                    "Group" defined in Section 4.1.k of this
                    Agreement or which might reasonably affect the
                    amount of the Bank's net operating loss;

                         (3)   To consult with Fourth and BANK IV
                    about the resolution of any such issues and not
                    to settle any such issues without giving Fourth
                    an opportunity to assume responsibility for the
                    resolution of such issues, at Fourth's expense,
                    if the effect of such settlement would be to
                    increase the liability of Fourth or any of its
                    affiliates for any tax for any period beginning
                    after the Effective Time or affect the amount of
                    the Bank's net operating loss unless Sellers
                    agree to pay and do pay to Fourth the full amount
                    of such increase in liability grossed up for any
                    federal or state tax attributable to such
                    payment; and 

                         (4)   That all existing income tax sharing or
                    allocation agreements or arrangements of any kind
                    between the Corporations and LSB or any other
                    member of such Group, whether or not in writing,
                    shall automatically be terminated at the
                    Effective Time and no further payments shall be
                    made by Bank thereunder except to the extent the
                    amount thereof has been taken into account in
                    calculating the Tangible Book Value of the Bank.


                                 ARTICLE IV

                       REPRESENTATIONS AND WARRANTIES


            4.1.    Representations and Warranties of Sellers.  Except
as expressly disclosed in the Disclosure Statement, Sellers jointly
and severally represent and warrant to Fourth as follows:


                    a.   Organization, Good Standing, and Authority. 
            Each Seller is a savings and loan holding company duly
            registered pursuant to the federal Home Owners' Loan Act. 
            Each of the Corporations is a corporation or savings bank
            duly organized, validly existing, and in good standing
            under the laws of the jurisdiction of  its incorporation,
            and each has all requisite corporate power and authority
            to conduct its business as it is now conducted, to own
            its properties and assets, and to lease properties used
            in its business.  None of the Corporations is in
            violation of its charter documents or bylaws, or of any
            applicable Law in any material respect, or in default in
            any material respect under any material agreement,
            indenture, lease, or other document to which it is a
            party or by which it is bound.  The deposits of the Bank
            are insured by the FDIC to the extent provided by the
            Federal Deposit Insurance Act and the Bank has paid all
            assessments and filed all reports required to be filed
            under the Federal Deposit Insurance Act of which failure
            to do so would have a material adverse effect upon the
            Bank.


                    b.   Binding Obligations; Due Authorization.  This
            Agreement constitutes the valid and binding obligation of
            each Seller, enforceable against it in accordance with
            the terms hereof, except as limited by applicable
            bankruptcy, insolvency, reorganization, moratorium, or
            other similar laws and equitable principles affecting
            creditors' rights generally.


                    c.   Absence of Default.  The execution and the
            delivery of this Agreement, the sale of the Shares, and
            the consummation of the other transactions contemplated
            hereby, and the fulfillment of the terms hereof will not
            (1) conflict with, or result in a breach of the terms,
            conditions, or provisions of, or constitute a default
            under the organizational documents or bylaws of any of
            the Corporations or under any agreement or instrument
            under which any of the Corporations or either Seller is
            obligated, or (2) violate any Law to which any of the
            Corporations or any Seller is subject.


                    d.   Subsidiaries.  LSB is the owner of all of the
            issued and outstanding capital stock of all classes of
            Prime.  The only Subsidiaries of the Bank are the
            following:


                    Name                      State of Incorporation
                    ----                      --------------------

                    e.   Capitalization.  The Bank is authorized to

            capitalization of each of the Bank's Subsidiaries
            excluding the Retained Corporations, is as follows:

                                                            Number of Shares
            Name                              Par Value   Issued   Outstanding
            ----                              ---------   -------   ---------

            Credit Card Center, Inc.          $   10.00   6,700       5,200

             Corp.                                 1.00   1,000       1,000
            United BankCard, Inc.              1,000.00     250         250
            

                    f.   Charter Documents.  True and correct copies
            of the charter documents and bylaws of each of the
            Corporations, with all amendments thereto, are included
            in the Disclosure Statement as Exhibits "E-1" to "E-8."


                    g.   Options, Warrants, and Other Rights.  None of
            the Corporations has outstanding any options, warrants,
            or rights of any kind requiring it to sell or issue to
            anyone any capital stock of any class and none of the
            Corporations has agreed to issue or sell any additional
            shares of its capital stock.


                    h.   Financial Statements.  Included in the
            Disclosure Statement as Exhibits "H-1" through "H-6" are 
            copies of the following financial statements, all of
            which are true and complete in all material respects and
            have been prepared in all material respects in accordance
            with GAAP and all applicable regulatory accounting
            principles consistently followed throughout the periods
            indicated, subject in the case of interim financial
            statements, to normal recurring year-end adjustments (the
            effect of which will not,  individually or in the
            aggregate, be materially adverse) and the absence of
            notes (which if presented would not differ materially
            from those included in the most recent year-end financial
            statements):


                         (1)   Audited Consolidated Financial
                    Statements of the Bank as of December 31, 1992,
                    and 1991, and for the fiscal years then ended
                    with auditors' report thereon and notes thereto,
                    which have been examined by Ernst & Young,
                    independent certified public accountants;

                         (2)   Thrift Financial Reports filed by the
                    Bank with the OTS for the quarters ended December
                    31, 1992, March 31, 1993, June 30, 1993, and
                    September 30, 1993; and

                         (3)   Unaudited financial statements of the
                    Bank as of October 31, 1993 and for the period
                    then ended.

            As soon as practicable between the date hereof and the
            Effective Time, Sellers will deliver to Fourth copies of
            monthly operating statements of the Bank and of all
            reports filed by any of the Corporations with any
            regulatory agencies.  The books of account of each of the
            Corporations and each of the Financial Statements fairly
            and correctly reflect and, when delivered, will reflect
            in all material respects in accordance with GAAP and all
            applicable rules and regulations of regulatory agencies
            applied on a consistent basis, the respective financial
            conditions and results of operations of each of the
            Corporations (except for the absence in the monthly
            operating statements of the Bank of certain information
            and footnotes normally included in financial statements
            prepared in accordance with GAAP).  There have been, and
            prior to the Effective Time there will be, no material
            adverse changes in the financial condition of the
            Corporations from December 31, 1992, other than changes
            made in the usual and ordinary conduct of the businesses
            of the Corporations, none of which has been or will be
            materially adverse and all of which have been or will be
            recorded in the books of account of the Corporations; and
            except as specifically permitted by this Agreement, there
            have been, and prior to the Effective Time there will be,
            no substantial adverse changes in the respective
            businesses, assets, properties, or liabilities, absolute
            or contingent, of any of the Corporations, or in their
            respective condition, financial or otherwise, from the
            date of the most recent of the Financial Statements that
            has  been delivered to Fourth on the date hereof other
            than changes occurring in the usual and ordinary conduct
            of the business of the Corporations, none of which has
            been or will be materially adverse and all of which have
            been or will be recorded in the respective books of
            account of the Corporations.  None of the Corporations
            has any contingent liabilities, other than letters of
            credit and similar obligations of the Bank incurred in
            the ordinary course of business, that are not described
            in or reserved against in the Financial Statements listed
            above.


                    i.   Real Properties.  Exhibit "I" to the
            Disclosure Statement is a complete list of all real
            estate owned or leased by any of the Corporations.  Each
            Corporation has good and marketable title in fee simple
            to all lands and buildings described in the Disclosure
            Statement as being owned by it, free and clear of all
            liens, encumbrances, and charges, except for Permitted
            Encumbrances.  All leases of real property to which any
            of the Corporations is a party as lessee, complete copies
            of each of which with all amendments thereto are included
            in Exhibit "I" to the Disclosure Statement, are each
            valid and enforceable in accordance with their respective
            terms except as enforcement may be limited by bankruptcy,
            insolvency, reorganization, moratorium, or similar Laws
            and equitable principles affecting creditors' rights
            generally, and there has been no material default by any
            party thereto.  No zoning ordinance prohibits, interferes
            with, or materially impairs the usefulness of any of the
            Facilities owned or used by any Corporation for the
            purposes for which it is now being used; and all the
            Facilities owned or leased by any of the Corporations are
            in good operating condition and repair, normal wear and
            tear excepted.


                    j.   Personal Property.  Except for leased
            properties, each of the Corporations has good and
            marketable title to all of the machinery, equipment,
            materials, supplies, and other property of every kind,
            tangible or intangible, contained in its offices and
            other facilities or shown as assets in its records and
            books of account, free and clear of all liens,
            encumbrances, and charges.  All leases of personal
            property to which any of the Corporations is a party as
            lessee are valid and enforceable in accordance with their
            terms, and there has been no material default by any
            party thereto.  The material items of personal property
            owned or leased by any of the Corporations are generally
            in good operating condition, normal wear and tear
            excepted.  


                    k.   Taxes.  LSB, Prime, the Bank, the
            Corporations, and the Retained Corporations are members
            of the same "affiliated group" (the "Group"), as defined
            in Section 1504(a)(1) of the Code. Each member of the
            Group has filed or caused to be filed, or a filing was
            made on its behalf, all tax returns and reports required
            to have been filed by or for it, and all material
            information set forth in such returns or reports is
            accurate and complete.  Each member of the Group has paid
            or made adequate provision for all taxes, additions to
            tax, penalties, and interest for all periods covered by
            those returns or reports.  There are no material unpaid
            taxes, additions to tax, penalties, or interest due and
            payable by any member of the Group, except for taxes and
            any such related liabilities being contested in good
            faith and disclosed in Exhibit "K" to the Disclosure
            Statement.  Each member of the Group has collected or
            withheld all amounts required to be collected or withheld
            by it for any taxes, and all such amounts have been paid
            to the appropriate governmental agencies or set aside in
            appropriate accounts for future payment when due.  Each
            member of the Group is in material compliance with, and
            its records contain all information and documents
            (including, without limitation, IRS Forms W-9) necessary
            to comply in all material respects with applicable
            information reporting and tax withholding requirements
            under federal, state, and local laws, rules, and
            regulations, and such records identify with specificity
            all accounts subject to backup withholding.  The
            Financial Statements fully and properly reflect, as of
            the dates thereof, the accrued taxes, additions to tax,
            penalties, and interest.  No extension of time for the
            assessment of deficiencies for any years is in effect. 
            No member of the Group has any knowledge of any
            unassessed tax deficiency proposed or threatened against
            any of them.


                    l.   Contracts.  Other than Permitted Contracts
            and agreements with customers of the Bank and with
            financial institutions entered into by the Bank in the
            ordinary course of its banking business, attached to the
            Disclosure Statement as Exhibit "L" is a list of all
            material contracts and other agreements and arrangements,
            both written and oral, to which Bank or any of the other
            Corporations is a party and which involve $10,000 or
            more, which affect or pertain to the operation of their
            respective businesses.  To the knowledge of Sellers, all
            parties thereto have in all material respects performed,
            and are in good standing with respect to, all the
            material obligations required to be performed under all
            such contracts and other  agreements and arrangements,
            and no obligation with respect thereto is overdue.  All
            of the material agreements of the Corporations, including
            without limitation the agreements disclosed in writing
            pursuant to this clause (l), are valid, binding, and
            enforceable in accordance with their terms, except as
            limited by applicable bankruptcy, insolvency,
            reorganization, moratorium, or similar Laws and equitable
            principles affecting creditors' rights generally.  Except
            as otherwise noted in Exhibit "L" to the Disclosure
            Statement, no material contract, lease, or other
            agreement or arrangement to which either Bank or one of
            the other Corporations is a party or as to which any of
            their assets is subject requires the consent of any third
            party in connection with this Agreement.  Except as
            described in Exhibit "L" to the Disclosure Statement,
            neither any Corporation nor any Seller has any knowledge
            of any threatened cancellation of, any outstanding
            disputes or default under, or of any basis for any claim
            of breach or default of, any material lease, contract, or
            other agreement or arrangement to which any of the
            Corporations is a party.  Except for Permitted Contracts
            and except as set forth in Exhibit "L" to the Disclosure
            Statement, neither the Bank nor any of the other
            Corporations is a party to:

                         (1)   Any contract for the purchase or sale
                    of any materials or supplies having an aggregate
                    purchase or sale price in excess of $10,000 which
                    contains any escalator, renegotiation, or
                    redetermination clause or which commits it for a
                    fixed term;

                         (2)   Any contract of employment with any
                    officer or employee not terminable at will
                    without liability on account of such termination;

                         (3)   Any management or consultation
                    agreement not terminable at will without
                    liability on account of such termination;

                         (4)   Any license or royalty agreement having
                    an aggregate future commitment to pay at least
                    $10,000, or union agreement, or loan agreement in
                    which any of the Corporations is the borrower;

                         (5)   Any contract, accepted order, or
                    commitment for the purchase or sale of materials,
                    services, or supplies having a total remaining
                    contract price in excess of $10,000;

                         (6)   Any contract containing any
                    restrictions on any party thereto competing with
                    the Bank, any of the other Corporations, or any
                    other person in the business of banking or
                    activities relating to banking;

                         (7)   Any other agreement which materially
                    affects the business, properties, or assets of
                    either Bank or one of the other Corporations, or
                    which was entered into other than in the ordinary
                    and usual course of business; or

                         (8)   Any letter of credit or commitment to
                    make any loan or group of loans to related
                    parties in an amount in excess of $500,000.

            None of LSB, Prime, or any of the Corporations has any
            knowledge based upon which it has formed a conclusion
            that a material loss is reasonably anticipated with
            respect to any of the agreements described in clause "l."


                    m.   Labor Relations; Employees; ERISA.  None of
            the Corporations is a party to or affected by any
            collective bargaining agreement, nor is any Corporation
            a party to any pending or, to the knowledge of Sellers,
            threatened labor dispute, organizational efforts, or
            labor negotiations.  Each of the Corporations has
            complied in all material respects with all applicable
            Laws relating to the employment of labor, including, but
            not limited to, the provisions thereof relating to wages,
            hours, collective bargaining, payment of social security
            taxes, and equal employment opportunity, the violation of
            which would have a materially adverse impact on their
            respective businesses.  None of the Corporations is
            liable for any arrears of wages or any taxes or penalties
            for failure to comply with any of the foregoing in an
            amount which would have a material adverse effect on the
            Bank or any of the Corporations.  None of the
            Corporations has any written or oral retirement, pension,
            profit sharing, stock option, bonus, or other employee
            benefit plan or practice other than group health and
            accident insurance except that Bank employees participate
            in Bank's and LSB's cafeteria plans, which include
            health, disability insurance (long and short term), life
            insurance, and supplemental life insurance, and LSB's
            401(k) plan, and thirteen employees in the United
            BankCard division of the Bank participate in a "frozen"
            401(k) plan.  The Bank is in the process of attempting to
            terminate this "frozen" plan.  None of the Corporations
            has violated any of the provisions of ERISA, and none of
            them has engaged in any "prohibited transactions" as such
            term  is defined in Section 406 of ERISA in an amount
            which would have a material adverse effect on the Bank or
            the Corporations.  There is no employee of any of the
            Corporations whose employment is governed by a written or
            oral employment agreement for a specific term of
            employment.


                    n.   Government Authorizations.  Each of the
            Corporations has all permits, charters, licenses, orders,
            and approvals of every federal, state, local, or foreign
            governmental or regulatory body required in order to
            permit it to carry on its business substantially as
            presently conducted except where the absence thereof
            would not have a material adverse effect on the Bank or
            the affected Corporation.  All such licenses, permits,
            charters, orders, and approvals are in full force and
            effect, and, to the knowledge of the Corporations and
            Seller, no suspension or cancellation of any of them is
            threatened and none of the Corporations knows of any fact
            or circumstance that will materially interfere with or
            materially adversely affect the renewal of any of such
            licenses, permits, charters, orders, or approvals; and
            none of such permits, charters, licenses, orders, and
            approvals will be affected by the consummation of the
            transactions contemplated by this Agreement.


                    o.   Insurance.  Exhibit "O" to the Disclosure
            Statement is a complete list of all insurance policies
            presently in effect and in effect during the past three
            years.  All the insurance policies and bonds currently
            maintained by any of the Corporations are in full force
            and effect.


                    p.   Litigation.  Exhibit "P" to the Disclosure
            Statement contains a true and complete list and brief
            description of all pending or, to the knowledge of any of
            the Corporations or any Seller, threatened, Litigation to
            which any of the Corporations is or would be a party or
            to which any of their assets is or would be subject. 
            Except as described on Exhibit "P" to the Disclosure
            Statement, none of the Corporations is a party to any
            Litigation other than routine litigation commenced by the
            Bank to enforce obligations of borrowers in which no
            counterclaims for any material amounts of money have been
            asserted or, to the knowledge of the Corporations or any 
            Seller, threatened.


                    q.   Brokers or Finders.  Except for an agreement
            with Lazard Freres & Co., whose fee will be paid by LSB,
            no broker, agent, finder, consultant, or other party
            (other than legal and accounting advisors) has been
            retained by either of the Sellers or any of the
            Corporations or is entitled to be paid based upon any
            agreements, arrangements, or understandings made by
            either of the Sellers or any of the Corporations in
            connection with any of the transactions contemplated by
            this Agreement.


                    r.   Environmental Compliance.  Except as
            disclosed in Exhibit "R", to Sellers' knowledge, each of
            the Corporations is in material compliance with all
            relevant Environmental Laws and none of the Corporations
            has any material Environmental Liabilities.  None of the
            Facilities is now being used or, to either Seller's
            knowledge, has at any time in the past ever been used for
            the storage (whether permanent or temporary), by any of
            the Corporations, or to the knowledge of either Seller,
            by third parties, disposal, or handling of any Hazardous
            Materials, nor are any Hazardous Materials located in,
            on, under, or at any of the Facilities.  No Corporation
            has received any notice of material violation of any
            Environmental Law, or any notice of any material
            potential Environmental Liabilities with respect to any
            of the Facilities or to any other properties and assets
            in which any Corporation has had an interest. 


                    s.   Employment of Aliens.  Each Corporation is in
            material compliance with the Immigration and Control Act
            of 1986.


                    t.   Notes and Leases.  All promissory notes and
            leases owned by the Bank or any other Corporation at the
            Effective Time will represent bona fide indebtedness or
            obligations to the Bank and are and will be fully
            enforceable in accordance with their terms without valid
            set-offs or counterclaims, except as limited by
            applicable bankruptcy, insolvency, reorganization,
            moratorium, or similar Laws and equitable principles
            affecting creditors' rights generally; provided, however,
            no representation or warranty is made in this Agreement
            as to the collectibility of such notes and leases.


                    u.   Updating of Representations and Warranties . 
            Between the date hereof and the Effective Time, Sellers
            will promptly disclose to Fourth in writing  any
            information of which either of them has actual knowledge
            (1) concerning any event that would render any
            representation or warranty of Sellers untrue if made as
            to the date of such event, (2) which renders any
            information set forth in this Agreement or the Disclosure
            Statement no longer correct in all material respects, or
            (3) which arises after the date hereof and which would
            have been required to be included in this Agreement or
            Disclosure Statement if such information had existed on
            the date hereof.


                    v.   True at Effective Time.  Except as otherwise
            specifically provided in this Agreement, all of the
            representations and warranties of Sellers set forth above
            will be true and correct at the Effective Time with the
            same force and effect as though such representations and
            warranties had been made at the Effective Time.


            4.2.    Representations and Warranties of Fourth.  Fourth
represents and warrants to Sellers as follows:


                    a.   Organization, Good Standing, and Authority.
            Fourth is a corporation duly organized, validly existing,
            and in good standing under the laws of the State of
            Kansas, and has all requisite corporate power and
            authority to conduct its business as it is now conducted,
            to own its properties and assets, and to lease properties
            used in its business.  Fourth is not in violation of its
            charter documents or bylaws, or of any applicable Law in
            any material respect, or in default in any material
            respect under any material agreement, indenture, lease,
            or other document to which it is a party or by which it
            is bound.


                    b.   Binding Obligations; Due Authorization.  This
            Agreement constitutes the valid and binding obligations
            of Fourth, enforceable against it in accordance with its
            terms, except as limited by applicable bankruptcy,
            insolvency, reorganization, moratorium, or other similar
            laws and equitable principles affecting creditors' rights
            generally.  The execution, delivery, and performance of
            this Agreement and the transactions contemplated hereby 
            have been duly authorized by the board of directors of
            Fourth.


                    c.   Absence of Default.  None of the execution or
            the delivery of this Agreement, the consummation of the
            transactions contemplated hereby, or the fulfillment of
            the terms hereof, will (1) conflict  with, or result in
            a breach of the terms, conditions, or provisions of, or
            constitute a default under the charter documents or
            bylaws of Fourth or under any agreement or instrument
            under which Fourth is obligated, or (2) violate any Law
            to which it is subject.


                    d.   Brokers or Finders.  No broker, agent,
            finder, consultant, or other party (other than legal and
            accounting advisors) has been retained by Fourth or is
            entitled to be paid based upon any agreements,
            arrangements, or understandings made by Fourth in
            connection with any of the transactions contemplated by
            this Agreement.


                    e.   Required Approvals.  Fourth knows of no
            reason that would preclude obtaining the Required
            Approvals in a timely manner, but various persons have
            the right to object to the granting of Required Approvals
            and the various governmental agencies involved can be
            expected to conduct various types of economic and other
            analysis, any one of which may cause a delay or denial of
            a requested approval.


                    f.   Capitalization of the Bank.  Fourth will
            contribute such additional capital to BANK IV as may be
            necessary in order for BANK IV to be well capitalized
            following consummation of the Purchase, the Merger, and
            the other transactions contemplated or permitted by this
            Agreement.  Fourth has sufficient capital resources to be
            able to make such additional capital contribution and to
            perform its obligations under this Agreement.


                                  ARTICLE V

                             CLOSING CONDITIONS


            5.1.    Conditions to Obligations of Fourth.  The
obligations of Fourth to purchase the Shares shall be subject to
the following conditions which may, to the extent permitted by Law,
be waived by Fourth at its option:


                    a.   Absence of Litigation.  No order, judgment,
            or decree shall be outstanding restraining or enjoining
            consummation of the purchase of the Shares, the Merger,
            or any of the other transactions permitted or
            contemplated by this Agreement; and no  Litigation shall
            be pending or threatened in which it is sought to
            restrain or prohibit the purchase of the Shares, the
            Merger, or any of the other transactions permitted or
            contemplated by this Agreement or to obtain other
            substantial monetary or other relief against one or more
            of the parties hereto in connection with this Agreement.


                    b.   Regulatory Approvals.  All Required Approvals
            shall have been procured (and shall continue to be in
            effect) and all other requirements prescribed by Law
            shall have been satisfied.


                    c.   Minimum Tangible Book Value of Bank.  The
            Tangible Book Value of the Bank as of the Effective Time,
            without taking into account any restructuring charges
            described in Section 2.3(b) of this Agreement, shall be
            not less than $41,000,000.  Such amount shall be
            substantiated by the total consolidated stockholder's
            equity of the Bank as reflected in the books of record
            and balance sheets of the Bank.  


                    d.   Opinion of Counsel.  Fourth shall have
            received the opinion of Housley Goldberg & Kantarian,
            P.C., counsel to the Corporations and Sellers,
            substantially in the form of Exhibit "A" hereto.


                    e.   Representations and Warranties; Covenants. 
            The representations and warranties of the Sellers
            contained in this Agreement shall have been true and
            correct in all material respects on the date made and
            shall be true and correct in all material respects at the
            Effective Time as though made at such time, excepting any
            changes occurring in the ordinary course of business,
            none of which shall have been materially adverse, and
            excepting any changes contemplated or permitted by this
            Agreement.  Sellers shall have performed all of their
            obligations under this Agreement.


                    f.   Certificates.  Sellers shall have delivered
            to Fourth a certificate, in form and substance
            satisfactory to Fourth, dated the Effective Time and
            signed by the chief executive officer and chief financial
            officer of each of the Corporations, certifying in such
            detail as Fourth may reasonably request the fulfillment
            of the foregoing conditions.

            
                    g.   Resignations.  Sellers shall have delivered
            to Fourth the written resignations, effective at the
            Effective Time, of those officers and directors of the
            Bank and the other Corporations as Fourth shall have
            requested at least two business days prior to the
            Effective Time.

            delivered to Fourth a copy of the Bank's audited
            consolidated Financial Statements as of December 31, 1993
            and for the year then ended, with auditor's report
            thereon and notes thereto.


                    i.   Lease of Equity Tower.  Northwest Tower
            Limited Partnership shall have entered into a lease as
            lessor of the Equity Tower, substantially in the form of
            Exhibit "C" hereto.


                    j.   Satisfactory Environmental Reports.  Fourth
            shall have received environmental assessment reports
            covering all of the Facilities, in form and substance
            reasonably satisfactory to Fourth, which do not cause
            Fourth reasonably to conclude that there are any material
            Environmental Liabilities associated with any of the
            Facilities.


            5.2.    Conditions to Obligations of Sellers.  The
obligation of Sellers to sell the Shares and to consummate the
transactions contemplated hereby shall be subject to the following
conditions which may, to the extent permitted by Law, be jointly
waived by Sellers at their option:


                    a.   General.  Each of the conditions specified in
            clauses a and b of Section 5.1 shall have occurred and be
            continuing.


                    b.   Representations and Warranties; Covenants. 
            The representations and warranties of Fourth contained in
            this Agreement shall have been true and correct in all
            material respects on the date made and shall be true and
            correct in all material respects at the Effective Time as
            though made at such time.  Fourth shall have duly
            performed all of its obligations under this Agreement.


                    c.   Minimum Purchase Price.  The Purchase Price
            shall be not less than $92,000,000, which minimum amount
            shall be reduced by the amount of the option price
            described in clause c of Section 7.5 if such option has
            been exercised by Sellers.


                    d.   Fairness Opinion.  LSB shall have received by
            February 10, 1994, a written opinion from Lazard Freres
            & Co. to the effect that the Purchase Price is fair to
            Sellers from a financial point of view.


                    e.   Opinion of Counsel.  Sellers shall have
            received the opinion of Foulston & Siefkin, counsel to
            Fourth, substantially in the form of Exhibit "B" hereto.


                    f.   Certificates.  Fourth shall have delivered to
            Sellers a certificate, in form and substance reasonably
            satisfactory to Sellers, dated the Effective Time and
            signed by the chief executive officer and chief financial
            officer of Fourth, certifying in such detail as Sellers
            may reasonably request, the accuracy of the
            representations and warranties and the fulfillment of the
            covenants of Fourth hereunder.


                    g.   LSB's Stockholder Approval.  The stockholders
            of LSB shall have approved this Agreement and the
            Purchase.


                    h.   Change in Treasury Regulations.  The United
            States Department of the Treasury shall not have finally
            adopted the proposed changes to the Treasury Regulations,
            at Sec. 1.1502-33 (56 FR 47379, Sept. 19, 1991, revised
            57 FR 53550, Nov. 12, 1992, revised, 57 FR 62251, Dec.
            30, 1992), nor shall have any other change in the Law
            occurred with the effect, in the reasonable judgment of
            Sellers based upon the advice of their tax advisors, that
            the tax basis of LSB or Prime in the Bank Stock shall be
            significantly reduced.


                    i.   Conveyance of Retained Corporations and
            Retained Assets.  On or before the Effective Time, all of
            the Retained Assets and all of the Bank's interests in
            the Retained Corporations shall have been transferred to
            Sellers or their designee or designees as provided in
            this Agreement.


                                 ARTICLE VI

                          TERMINATION OF AGREEMENT


            6.1.    Mutual Consent; Termination Date.  This Agreement
shall terminate at any time when the parties hereto mutually agree
in writing.  This Agreement may also be terminated at the election
of either Sellers (acting jointly) or Fourth, upon written notice
from the party electing to terminate this Agreement to the other
party if, without fault on the part of the party electing to
terminate this Agreement, there has been a denial of a Required
Approval or the imposition of one or more terms (not including a
requirement to divest a single branch of the Bank not located in
Oklahoma City) reasonably deemed onerous by Fourth or Sellers as a
condition to obtaining a Regulatory Approval.  Unless extended by
written agreement of the parties, this Agreement shall terminate if
all conditions to the obligations of the parties hereto have not
occurred on or before June 30, 1994.


            6.2.    Election by Fourth.  This Agreement shall
terminate at Fourth's election, upon written notice from Fourth to
Sellers if any one or more of the following events shall occur and
shall not have been remedied to the satisfaction of Fourth within
30 days after written notice is delivered to Seller:  (a) there
shall have been any uncured material breach of any of the
obligations, covenants, or warranties of the Sellers hereunder; or
(b) there shall have been any written representation or statement
furnished by the Sellers hereunder which at the time furnished is
false or misleading in any material respect in relation to the size
and scope of the transactions contemplated by this Agreement.


            6.3.    Election by Sellers.  This Agreement shall
terminate at the election of Sellers (acting jointly) upon written
notice from Sellers to Fourth if any one or more of the following
events shall occur and shall not have been remedied to its
satisfaction within 30 days after written notice is delivered to
Fourth:  (a) there shall have been any uncured material breach of
any of the obligations, covenants, or warranties of Fourth
hereunder; or (b) there shall have been any written representation
or statement furnished by Fourth hereunder which at the time
furnished is false or misleading in any material respect in
relation to the size and scope of the transactions contemplated by
this Agreement.


                                 ARTICLE VII

                               INDEMNIFICATION


            7.1.    Effect of Closing.  Except as provided in this
Section, closing of the transactions contemplated by this Agreement
shall not prejudice any claim for damages which any of the parties
hereto may have hereunder in law or in equity, due to an uncured
material default in observance or the due and timely performance of
any of the covenants and agreements herein contained or for the
material breach of any warranty or representation hereunder, unless
such observance, performance, warranty, or representation is
specifically waived in writing by the party making such claim.  If
any warranty or representation contained herein is or becomes
untrue or breached in any material respect (other than by reason of
any willful misrepresentation or breach of warranty) and such
breach or misrepresentation is promptly communicated to the other
parties in writing prior to the Effective Time, such non-breaching
parties shall have the right (jointly in the case of Sellers), at
their sole option, either to waive such misrepresentation or breach
in writing or to terminate this Agreement, but in either such
event, the breaching parties shall not be liable to the other
parties for any such damages, costs, expenses, or otherwise by
reason of such breach or misrepresentation.  If such non-breaching
parties elect to close the transactions contemplated by this
Agreement notwithstanding the written communication of such breach
or misrepresentation, they shall be deemed to have waived such
breach or misrepresentation in writing.  Similarly, if Fourth
receives an environmental assessment report on the Facilities
pursuant to Section 5.1(j) indicating the existence of any
Environmental Liability and elects to close the transactions
contemplated by this Agreement, it shall be deemed to have waived
all right to indemnification with respect thereto.


            7.2.    General Indemnification.  Subject to the
limitations on the liability of Sellers contained in Section 7.1
and this Section 7.2, Sellers shall be jointly and severally liable
for, and shall defend, save, indemnify, and hold harmless Fourth,
BANK IV, the Corporations, and their respective successors,
officers, directors, employees, and agents, and each of them
(hereinafter individually referred to as an "Indemnitee" and
collectively as "Indemnitees") against and with respect to any
losses, liabilities, claims, diminution in value, litigation,
demands, damages, costs, charges, reasonable legal fees, suits,
actions, proceedings, judgments, expenses, or any other losses
(herein collectively referred to as "Indemnifying Losses") that may
be sustained, suffered, or incurred by, or obtained against, any
Indemnitee arising from or by reason of the material uncured breach
or nonfulfillment of any of the warranties, agreements, or
representations made by the Sellers, in this Agreement; provided,
however that the liability of Sellers to defend, save, indemnify,
and hold harmless any of the Indemnitees for any liabilities,
claims, or demands indemnified  under this Section 7.2 (but not
under Section 7.5, 7.6, or 7.7) or any damages, costs, charges,
reasonable legal fees, suits, actions, proceedings, or judgments
received, incurred, filed, or entered thereon, shall be limited to
the amount by which all such liabilities, claims, and demands so
discovered or made, and all damages, costs, charges, reasonable
legal fees, suits, actions, proceedings, judgments, expenses, and
other losses recovered, incurred, filed, or entered thereon or in
connection therewith, exceed $1,000,000 in the aggregate, net of
income tax effect and such liability shall not exceed $25,000,000. 
Indemnitees shall be obligated to exhaust all reasonably available
remedies as a condition to being indemnified hereunder but not as
a condition to giving notice pursuant to Sections 7.3 and 7.4.  It
is agreed that the indemnification obligations of Sellers hereunder
shall be solely for the benefit of the Indemnitees and may not be
enforced by any insuror under any subrogation or similar agreement
or arrangement or by any governmental agency except as a receiver
for an Indemnitee. 


            7.3.    Procedure.  If any claim or demand shall be made
or liability asserted against any Indemnitee, or if any Litigation,
suit, action, or administrative or legal proceedings shall be
instituted or commenced in which any Indemnitee is involved or
shall be named as a defendant either individually or with others,
and if such Litigation, claim, demand, liability, suit, action, or
proceeding, if successfully maintained, will result in any
Indemnifying Losses as defined in Section 7.2, Fourth shall give
Sellers written notice thereof as soon as practicable but within 20
days (ten days in the case of legal process) after it acquires
knowledge thereof.  If the Indemnifying Loss arises otherwise,
Fourth shall give notice to Sellers within 20 days of the discovery
of the basis therefor.  If, within 20 days after the giving of such
notice, Fourth receives written notice from Sellers stating that
Sellers dispute or intend to defend against or prosecute, as the
case may be, such claim, demand, liability, suit, action, or
proceeding, then Sellers shall have the joint right to select
counsel of their choice and to dispute or defend against,
prosecute, or settle such claim at their expense, and the
Indemnitees shall fully cooperate with Sellers in such dispute,
prosecution, defense or settlement so long as Sellers are
conducting such dispute, defense, or prosecution diligently and in
good faith.  If no such notice of intent to dispute or defend is
received by Fourth within the aforesaid 20-day period, of if such
diligent and good faith defense is not being, or ceases to be,
conducted, Fourth shall have the right, directly or through one or
more of the Indemnitees, to dispute and defend against the claim,
demand, or other liability at the cost and expense of Sellers, to
settle such claim, demand, or other liability, together with
interest or late charges thereon, and in either event to be
indemnified as provided in this Agreement so long as Fourth
conducts such defense diligently and in good faith.  If any event
shall occur that would entitle Indemnitees to a right  of
indemnification hereunder, any loss, damage, or expense subject to
indemnification shall be the after-tax net loss to the Indemnitees
(in excess of $1,000,000 but not to exceed $25,000,000, as provided
in the preceding section) after due allowance for the income tax
effect, if any, of amounts to be received by the Indemnitees
hereunder, insurance, or offsetting income or assets resulting
therefrom.


            7.4.    Survival of Representations and Warranties. 
Notwithstanding any rule of law or provision of this Agreement to
the contrary, the representations and warranties of Sellers
contained in this Agreement shall survive the Closing and the
Purchase and the closing of the transactions described in this
Agreement; provided, however, that (except for the indemnification
obligations contained in Sections 7.6 and 7.7 hereof, as to which
there shall be no time limit) no claim for indemnification or
breach of warranty under this Agreement shall be valid unless an
Indemnitee shall have given written notice of its assertion or
claim to Seller:

                    (a)  within three years from the Effective Time in
            the case of a claim for breach of any representation or
            warranty contained in Section 4.1.k of this Agreement;

                    (b)  by the earlier of October 31, 1998 or 30 days
            after the date on which the Internal Revenue Service
            completes its examination of Fourth's 1994 federal income
            tax return and gives Fourth written notice of any
            proposed adjustments (provided that both such periods
            shall be extended by a period of time equal to 30 days
            plus the length of in each case any periods for which LSB
            shall have agreed to a tolling of any limitation period
            applicable to the assertion against LSB or any member of
            the Group described in Section 4.1.k of any deficiency by
            the Internal Revenue Service) in the case of a claim
            under Section 7.5 of this Agreement; and

                    (c)  within two years of the Effective Time in all
            other cases.


            7.5.    Special Indemnification.  

                    (a)  Separate and apart from the indemnification
            provisions in the preceding sections of this Article VII,
            and not subject to the deductibility and maximum
            liability provisions contained in Section 7.2, Sellers
            jointly and severally agree to indemnify BANK IV and
            Fourth from any reduction in the aggregate amount of the
            Bank's net operating loss carryforward for federal income
            tax purposes (to the extent an adjustment has not already
            been made pursuant to Section 2.4(b)), below $64,000,000;
            provided, however, that such reduction results from
            either (i) a reduction required by final action related
            to an audit or adjustment by the Internal Revenue Service
            and made retroactive to the period prior to the Effective
            Time or (ii) a reduction in the net operating loss
            carryforward of the Bank at the Effective Time
            attributable to the consolidated taxable income of LSB
            (after taking into account the taxable income or loss of
            each member of the consolidated group contained in the
            consolidated return of LSB and taking into account the
            allocations of consolidated income, gain, and loss
            affecting such net operating loss carryforward),
            including the effects of the sale of the Retained Assets
            and Retained Corporations to Sellers and all
            extraordinary items.  The payment to be made by Sellers
            shall be equal to the product of (a) the dollar amount of
            the reduction required in (i) above and/or the reduction
            determined in (ii) above, and (b) a fraction, the
            numerator of which shall be $10,500,000, and the
            denominator of which shall be $64,000,000.  However, to
            the extent that an adjustment merely postpones the
            related tax benefit to BANK IV or Fourth to a later,
            reasonably ascertainable period, then such adjustment
            shall not be subject to this special indemnification.

                    (b)  If there is an audit or similar inquiry of
            the Internal Revenue Service of any tax return which may
            have the effect of reducing the Bank's net operating loss
            as of or for a period prior to the Closing, all parties
            to this Agreement shall cooperate with each other as to
            the determination of the adjustments under such audit,
            shall make available to each other as may reasonably be
            requested all information, records, and documents until
            the expiration of any applicable statute of limitations
            or extensions thereof.

                    (c)  Sellers shall have the right and option,
            exercisable at any time prior to the business day next
            preceding the Effective Time, by giving written notice to
            Fourth, to elect to have the Purchase Price reduced by
            $600,000 in consideration of the termination of Section
            7.5(a) of this Agreement, in which event the provisions
            of Section 7.5(a) shall thereupon be of no further force
            and effect.


            7.6.    Separate Indemnification for Environmental
Matters.    Separate and apart from the indemnification provided in
the preceding sections of this Article VII, and not subject to the 
$1,000,000 deductibility and $25,000,000 maximum liability
provisions contained in Section 7.2, Sellers shall be jointly and
severally liable for, and shall forever defend, save, indemnify,
and hold harmless Fourth, Bank, and BANK IV from and against, any
and all Environmental Liabilities that may be incurred or sustained
by, or rendered against Fourth, Bank, or BANK IV arising in any
manner out of the direct or indirect ownership or operation at any
time by the Bank or by any of its  current or former Subsidiaries
of any current or former Non-Bank Facility (as hereinafter
defined).  "Non-Bank Facility" means any interest in real property,
building, plant, structure, or equipment which is not (i) currently
or formerly owned or operated by the Bank in the ordinary course of
its banking business as a banking facility, (ii) the Equity Tower,
(iii) property located at Coffee Creek Road and Kelly Avenue,
Edmond, Oklahoma, (iv) an OREO Property, or (v) collateral held as
security for loans or participations.  


            7.7.    Separate Indemnification for Barki Litigation,
COMAC, and 401(k) Plan.  Separate and apart from the
indemnification provided in the preceding sections of this Article
VII, and not subject to the $1,000,000 deductibility and
$25,000,000 maximum liability provisions contained in Section 7.2,
Sellers shall be jointly severally liable for, and shall forever
defend, save, indemnify, and hold harmless Fourth, BANK IV, and
Bank from and against any and all losses, expenses (including
amounts reasonably paid in settlement), liabilities, costs,
penalties, damages, and judgments that may be incurred or sustained
by, or rendered against, Fourth, BANK IV, or Bank arising out of or
associated in any manner with (i) the United BankCard division
"frozen" 401(k) plan described in Section 4.1(m) of this Agreement,
(ii) Mai-Li Barki vs. Equity Bank for Savings, F.A. et al., Case
No. CJ-91-90852, filed in the District Court of Oklahoma County,
Oklahoma or otherwise out of the claims contained in such case, or
(iii) the pending Internal Revenue Service examination of COMAC
Financial Services Ltd Partnership described in Exhibit "K" to the
Disclosure Statement; provided, however, BANK IV shall be
responsible for the payment of one-half of the out-of-pocket
attorneys' fees and costs incurred in connection with the Barki
litigation.  Sellers shall have the right to defend the Barki
action in accordance with the provisions of Section 7.2 of this
Agreement.  


            7.8.    Director and Officer Indemnification.  From and
after the Effective Time, Fourth shall indemnify, defend, and hold
harmless each person who is now, or has been at any time prior to
the date hereof or who becomes prior to the Effective Time, an
officer, director, or employee of any of the Corporations (the
"Bank Indemnified Parties") against all losses, claims, damages,
costs, expenses (including attorney's fees), liabilities, or
judgments or amounts that are paid in settlement (which settlement
shall require the prior written consent of Fourth, which consent
shall not be unreasonably withheld) of or in connection with any
claim, action, suit, proceeding, or investigation (each a "Claim")
in which a Bank Indemnified Party is, or is threatened to be made,
a party based in whole or in part on or arising in whole or in part
out of the fact that such person is or was a director, officer, or
employee of a Corporation if such Claim pertains to any matter or
fact arising, existing, or occurring prior to the Effective Time
(but excluding the transactions expressly contemplated by this
Agreement), regardless of whether such Claim is asserted or claimed
prior to, or at or after, the Effective Time (the "Indemnified
Liabilities") to the full extent required under applicable law in
effect as of the date hereof or as amended applicable to a time
prior to the Effective Time or as required under the Bank's charter
and bylaws (and Fourth shall pay expenses in advance of the final
disposition of any such action or proceeding to each Bank
Indemnified Party to the full extent  permitted by applicable law
in effect as of the date hereof or as amended applicable to a time
prior to the Effective Time upon receipt of any undertaking
required by applicable law).  Any Bank Indemnified Party wishing to
claim indemnification under this Section 7.8 upon learning of any
Claim, shall notify Fourth (but the failure so to notify Fourth
shall not relieve Fourth from any liability which it may have under
this Section 7.8 except to the extent such failure materially
prejudices Fourth) and shall deliver to Fourth copies of all demand
letters, notices, summonses, pleadings, and other documents which
such party may have received relating to such Claim. The
obligations of Fourth described in this Section 7.8 continue in
full force and effect, without any amendment thereto, for a period
of three years from the Effective Time; provided, however, that all
rights to indemnification in respect of any Claim asserted or made
within such period shall continue until the final disposition of
such Claim.


                                ARTICLE VIII

                                MISCELLANEOUS


            8.1.    Expenses.  Whether or not the Purchase is effected

incurring such expense.

(a) If to Fourth, addressed to Ronald L. Baldwin, Executive Vice
President, Post Office Box 2360, Tulsa, Oklahoma 74101-2360; and

President, Post Office Box 754, 16 South Pennsylvania, Oklahoma
City, Oklahoma 73107, or to such other person or such other address
as shall have been furnished in writing in the manner provided
herein for giving notice.


            8.3.    Time.  Time is of the essence of this Agreement.


            8.4.    Law Governing.  This Agreement shall, except to
the extent federal law is applicable, be construed in accordance
with and governed by the laws of the State of Kansas, without
regard to the principles of conflicts of laws thereof.


            8.5.    Entire Agreement; Amendment.  This Agreement
contains and incorporates the entire agreement and understanding of
the parties hereto with respect to the subject matter hereof and
supersedes all prior negotiations, agreements, letters of intent,
and understandings.  This Agreement may only be amended by an
instrument in writing duly executed by Fourth and Sellers and all
attempted oral waivers, modifications, and amendments shall be
ineffective.


            8.6.    Successors and Assigns.  The rights and
obligations of the parties hereto shall inure to the benefit of and
shall be binding upon the successors and permitted assigns of each
of them; provided, however, that this Agreement or any of the
rights, interests, or obligations hereunder may not be assigned by
any of the parties hereto without the prior written consent of the
other parties hereto.


            8.7.    Cover, Table of Contents, and Headings.  The
cover, table of contents, and the headings of the sections and
subsections of this Agreement are for convenience of reference only
and shall not be deemed to be a part hereof or thereof or taken
into account in construing this Agreement.


            8.8.    Counterparts.  This Agreement may be executed in
one or more counterparts, each of which shall be deemed an original
but which together shall constitute but one agreement.


            8.9.    No Third Party Beneficiaries.  Except as
specifically provided herein, nothing in this Agreement shall
entitle any person other than Sellers and Fourth to any claim,
cause of action, remedy, or right of any kind.


            8.10.   Severability.  Whenever possible, each provision
of this Agreement shall be interpreted in such a manner as to be
effective and valid under applicable law, but if any provision of
this Agreement is held to be prohibited by or invalid under
applicable law, such provision will be ineffective only to the
extent of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this
Agreement.


            IN WITNESS WHEREOF, the parties hereto have caused this

Board of Directors
Fourth Financial Corporation
Wichita, Kansas


Gentlemen:


            We have acted as counsel to LSB Industries, Inc. ("LSB")
and Prime Financial Corporation ("Prime") (collectively "Sellers")
in connection with the preparation of the Stock Purchase Agreement,
dated as of February 8, 1994, among Fourth Financial Corporation
and Sellers (the "Agreement").  This Opinion Letter is provided to
you at the request of Seller pursuant to Section 5.1(d) of the
Agreement.  Except as otherwise indicated herein, capitalized terms
used in this Opinion Letter are defined in the Agreement or the
Accord described below.


            This Opinion Letter is governed by, and shall be
interpreted in accordance with, the Legal Opinion Accord (the
"Accord") of the ABA Section of Business Law (1991).  As a
consequence, it is subject to a number of qualifications,
exceptions, definitions, limitations on coverage and other
limitations, all as more particularly described in the Accord, and 
this Opinion Letter should be read in conjunction therewith.  The
law covered by the opinions expressed herein is limited to the
Federal Law of the United States, the corporate Law of the State of
Deleware, and the Law of the State of Oklahoma.  The confirmation
concerning Litigation below is further limited to our Actual
Knowledge after interviews with corporate officers and review of
copies of documents relating to Litigation furnished to us by such
officers.  Based upon and subject to the foregoing, we are of the
opinion that:


                    1.   Organization and Good Standing.  Each Seller
            is a savings and loan holding company duly registered
            pursuant to the federal Home Owners' Loan Act.  Sellers
            and the Corporations are each a corporation or savings
            bank duly organized, validly existing, and in good
            standing under the laws of the jurisdiction of its
            incorporation.


                    2.   Binding Obligations.  The Agreement is
            enforceable against each Seller.


                    3.   Absence of Default.  None of the execution or
            the delivery of the Agreement, the consummation of the
            Purchase, or the performance by Sellers of the terms
            thereof, will (a) violate the Constituent Documents of
            any of the Corporations or of either Seller, (b) breach
            or result in a default under any agreement or instrument
            under which any of the Corporations or either Seller is
            obligated of which we have Actual Knowledge, or (c)
            violate any Laws to which any of the Corporations or
            either Seller is subject.


                    4.   Capitalization.  The Bank is authorized to
            issue 1,000,000 shares of common stock, par value $.01
            per share, of which 100,000 shares are validly issued and
            outstanding.  Prime is the owner, free and clear of all
            encumbrances, liens, and security interests whatsoever,
            of all issued and outstanding shares of Bank Stock.  LSB
            owns all of the issued and outstanding capital stock of
            Prime.


                    5.   Options.  None of the Corporations has
            outstanding any options, warrants, or rights of any kind
            requiring it to sell or issue to anyone any capital stock
            of any class, and to our Actual Knowledge, none of the
            Corporations has agreed to sell any shares of its capital
            stock.  


                    6.   Governmental Approvals.  The execution,
            delivery, and performance of the Agreement by Sellers do
            not require any approval, authorization, consent,
            exemptions, notices of intent not to disapprove, or other
            action of any regulatory body, administrative agency, or
            any other governmental body or any filing with any
            governmental body to which either Seller or any
            Corporation is subject, other than approvals of or
            filings with the Board, the OTS, and the Comptroller. 
            All such requisite approvals, authorizations, consents,
            exemptions, and notices have been taken by the
            appropriate governmental body.


            We hereby confirm to you that the Disclosure Statement
contains a true and complete list and brief description of all
Litigation pending or overtly threatened in writing to which any of
the Corporation is or would be a party or to which any of their
assets is or would be subject.  Except as set forth in Exhibit "P"
to the Disclosure Statement, none of the Corporations is a party to
any Litigation other than routine litigation commenced by the Bank
to enforce obligations of borrowers in which no counterclaims for
any material amounts of money have been asserted or overtly
threatened in writing.


            The phrase "Primary Lawyer Group", as used in the Accord,
is hereby modified and, for the purposes of applying the Accord to
this Opinion Letter, the Primary Lawyer Group means only the
lawyers in this firm who have given substantive legal attention to
representation of Sellers and the Corporations in connection with
the Transaction.


            This Opinion Letter may be relied upon by you only in
connection with the Transaction and may not be used or relied upon
by you or any other person for any purpose whatsoever, except to
the extent authorized in the Accord, without in each instance our
prior written consent.


                               Very truly yours,




                               Housley Goldberg & Kantarian P.C.

Except as otherwise indicated herein, capitalized terms used in

            Based upon and subject to the foregoing, we are of the
opinion that:


                    1.   Organization, Good Standing, and Authority. 
            Fourth is a bank holding company duly registered pursuant
            to the Bank Holding Company Act.  Fourth is a corporation
            validly existing and in good standing under the laws of
            the jurisdiction of its incorporation.


                    2.   Binding Obligations.  The Agreement is
            enforceable against Fourth.


                    3.   Absence of Default.  None of the execution or
            the delivery of the Agreement, the consummation of the
            Purchase, or the performance by Fourth of its agreements
            therein will (a) violate the Constituent Documents of
            Fourth, (b) breach or result in a default under any
            agreement or instrument under which Fourth is obligated
            of which we have Actual Knowledge, or (c) violate any
            Laws to which Fourth is subject.


                    4.   Governmental Approvals.  The execution,
            delivery, and performance of the Agreement by Fourth does
            not require any approval, authorization, consent,
            exemptions, notices of intent not to disapprove, or other
            action of any regulatory body, administrative agency, or
            any other governmental body or any filing with any
            governmental body to which Fourth is subject, other than
            approvals of or filings with the Board, the Comptroller,
            and the OTS.  All such requisite approvals,
            authorizations, consents, exemptions, and notices have
            been taken by the appropriate governmental body.


            The phrase "Primary Lawyer Group", as used in the Accord,
is hereby modified and for the purposes of applying the Accord to
this Opinion Letter the Primary Lawyer Group means only the lawyers

adequate value, or (iii) take any other action which would violate
the terms of the Stock Purchase Agreement.


            Section 8.  The present board of directors and officers
of BANK IV shall continue to serve as the board of directors and
officers of the Association until the next annual meeting or until
