Item 5.   Other Events.

          LSB Industries, Inc. ("LSB"), Prime Financial Corporation
("Prime"), a wholly-owned subsidiary of LSB (LSB and Prime are collectively
called the "Company"), and Fourth Financial Corporation ("Fourth") entered
into a Stock Purchase Agreement, dated as of February 9, 1994 (the "Stock
Purchase Agreement"), pursuant to which at the closing the Company has
agreed to sell, and Fourth has agreed to purchase, all of the issued and
outstanding shares of capital stock of Equity Bank for Savings, F.A. (the
"Bank"), pursuant and subject to the terms of the Agreement.  The Bank is a
wholly-owned subsidiary of Prime, and Prime is a wholly-owned subsidiary of
LSB.  The Bank comprises LSB's Financial Services Business.

          The consummation of the Stock Purchase Agreement is
conditioned upon, among other things, (i) the Company and Fourth obtaining
appropriate regulatory approvals, and (ii) the Company obtaining shareholder
approval.  Closing of the transactions contemplated by the Stock Purchase
Agreement is anticipated to occur on or before June 30, 1994.  If such is not
closed on or before June 30, 1994, the Stock Purchase Agreement shall
terminate unless extended by written agreement of the parties.

          The purchase price to be paid by Fourth to the Company for the
Bank at the closing of the transaction contemplated by the Stock Purchase
Agreement is estimated to be approximately $92 million.  The exact amount
of such purchase price is to be determined at the closing based on a formula
and is to be equal to the sum of the following: (i) the tangible book value of
the Bank (defined as the aggregate consolidated stockholders' equity of the
Bank, calculated in accordance with generally accepted accounting principles,
less the amounts in certain accounts relating to purchased mortgage servicing
rights, goodwill, and United BankCard goodwill, net of accumulated
amortization) at the closing, plus a premium over the Bank's tangible book
value of the following determined at the closing: (a) $9.3 million for the
Bank's credit card business, (b) 1% of the aggregate of the unpaid principal
balance at closing of the Bank's loans secured by fixed rate mortgages having
fully amortizing original terms of fifteen (15) years or less, excluding loans
originated after October 31, 1993, (c) 6% of the aggregate unpaid principal
balance at closing of the Bank's loans secured by fixed rate mortgages having
fully amortizing original terms in excess of fifteen (15) years but not more
than thirty (30) years, excluding loans originated after October 31, 1993, and
(d) 2% of the aggregate unpaid principal balance at the closing of the Bank's
loans secured by variable rate mortgages, excluding loans originated after
October 31, 1993; (ii) an amount at the closing equal to the unamortized
discount on the Bank's mortgages included in (i)(b), (c), and (d) above; (iii)
an amount at the closing equal to (a) 0.65% of the aggregate unpaid principal
balance of loans serviced by the Bank prior to March 1, 1993, on which the
Bank performs mortgage servicing (other than loans serviced for the account
of the Bank), (b) 1% of such balance on such loans serviced by the Bank that
were originated after March 31, 1993, secured by fixed or adjustable rate
mortgages of fully amortizing original terms of at least ten (10) but not more
than fifteen (15) years, and (c) 1.25% of such balance on such loans
originated on or after March 1, 1993, secured by fixed or adjustable rate
mortgages having original fully amortized terms of more than fifteen (15) but
not more than thirty (30) years; (iv) an amount obtained by subtracting the
"required reserve" (as defined below) from the Bank's actual loan loss reserve
account at the closing, with the "required reserve" meaning $2.7 million as
adjusted by the amount by which the Bank's loan loss account would have
been adjusted at the closing under normal and prudent banking practice to
reflect aggregate changes of at least $500,000 occurring subsequent to
October 31, 1993, in the quality of commercial and energy loans held by the
Bank on October 31, 1993, or originating since October 31, 1993, and not
reviewed in advance by Fourth; provided, that no such change in the quality
of a loan is to be included in the calculation to the extent such change has
been reflected in the tangible book value of the Bank at the closing or if such
change is less than $25,000; (v) to the extent not otherwise reflected in the
tangible book value of the Bank, an amount, either positive or negative, by
which the aggregate fair market value of the Bank's securities portfolio at the
closing differs from the Bank's book value of such portfolio at the closing; 
(vi) the difference, positive or negative, between the carrying value of the 
Bank's time deposits and the aggregate value of such deposits after repricing 
them to the Treasury yield curve at the closing; (vii) $10.5 million for the 
Bank's net operating loss; (viii) $11.0 million for the Bank's deposit balance; 
and, (ix) $1.4 million for certain of the Bank's branches.

       The percentages specified in (i)(b) and (c) immediately above are
determined utilizing the spread between the Bank's average portfolio yield
and FNMA required thirty (30) day yield as of August 31, 1993.  If, at the
time of the closing, such spreads have fluctuated by more than 0.25%, the
applicable percentages in such subparagraphs (i)(b) and (c) will be adjusted
up or down by one-fourth of 1% for each full one-eighth of 1% change in the
spread, in the case of loans with an original term of fifteen (15) years or 
less, and by three-eighths of 1% for each full one-eighth of 1% change, in the 
case of loans with an original term of more than fifteen (15) but not more than
thirty (30) years.

       Based on the above, the Company estimates that at the closing the
purchase price will be approximately $92 million, which amount is estimated
based upon estimates which cannot be definitively determined until the
closing.  Among other things, management of the Company has estimated the
Bank's earnings through March 31, 1994, in order to estimate tangible net
worth of the Bank, a major component of the purchase price, and made
estimates with respect to the other variables which make up the purchase
price.  The purchase price will be affected by the results of operations of and
the fluctuation of interest rates between the date of this report and the
closing.  Notwithstanding the foregoing, if the purchase price, as finally
determined at the closing, is less than $92 million, the Company may, at its
option, terminate the Stock Purchase Agreement.

          Under the Agreement, the Company has agreed to purchase
from the Bank at least one (1) business day prior to the closing those
subsidiaries of the Bank ("Retained Corporations") that hold any of the assets
contributed by the Company and several of its subsidiaries to a wholly-owned
subsidiary of the Bank at the time that the Company acquired the Bank in
March, 1988 (the "Transferred Assets").  The Company has agreed to
purchase such Retained Corporations for an amount equal to the Retained
Corporations' carrying value of the Transferred Assets at the time that the
Company acquires the Retained Corporations, which the Company anticipates
to be approximately $65.4 million.  Under the Agreement, the Company has
further agreed to purchase from the Bank at the closing (i) the loan and
mortgage on and an option to purchase the twenty-two (22) story Equity
Tower located in Oklahoma City, Oklahoma ("Equity Tower Loan"), for an
amount equal to the Bank's carrying value of such Equity Tower Loan at the
time of closing, and (ii) all other real estate owned by the Bank as a result of
foreclosure ("OREO") for an amount equal to the carrying value thereof as
shown on the books of the Bank at the closing.  As of December 31, 1993, the
carrying value of the Equity Tower Loan and the OREO on the books of the
Bank was approximately $20.5 million.  In addition, the Company has further
agreed under the Agreement to acquire from the Bank at the closing all
outstanding accounts receivable ("Receivables") previously sold by the
Company and certain other subsidiaries of the Company to the Bank under
various purchase agreements, dated March 8, 1988, which purchase
agreements were approved by the appropriate regulatory authority at such
time, that have not been previously repurchased as of the closing for the
aggregate carrying value of such Receivables on the books of the Bank as of
the closing.  As of February 18, 1994, there were approximately $25.8 million
of such Receivables outstanding on the books of the Bank.  The Company
anticipates, however, that if the closing occurs on or about June 30, 1994, that
there will be less than $10 million of such Receivables on the books of the
Bank at such closing.

          The Company anticipates, although there are no assurances, that
it will obtain from a subsidiary of Fourth (i) on a short-term basis, financing
to purchase the Retained Corporations from the Bank, which financing, plus
interest, will be repaid with a portion of the proceeds of the purchase price
received from Fourth as soon as possible after the closing, and (ii) a line of
credit to finance the accounts receivable of the Company and certain of its
subsidiaries, including those Receivables to be repurchased by the Company
from the Bank at closing.

          Under the Agreement, the Company has made certain
representations and warranties.  The Company has also agreed under the
Stock Purchase Agreement to indemnify Fourth and its wholly-owned
subsidiary, Bank IV Oklahoma, National Association ("Bank IV"), against,
among other things, (i) losses that may be sustained by them due to breach
of any representations or warranties made by the Company in the Stock
Purchase Agreement or failure by the Company to fulfill any agreement made
by the Company in the Stock Purchase Agreement, provided losses by Fourth
and Bank IV under (i) exceed $1 million in the aggregate, net of income tax
effect, and such liability by the Company shall not exceed $25 million; (ii) the
Bank's net operating loss for federal income tax purposes ("NOL") reducing
below $64 million if such a reduction is (a) due to a final action relating to
an audit or adjustment by the Internal Revenue Service and such is
retroactive to the period prior to the closing of the Agreement or (b)
attributable to the consolidated taxable income of LSB, provided that the
Company's liability for such reduction in the NOL of the Bank shall not
exceed an amount equal to the product of the dollar amount of such
reduction by a fraction, the numerator of which shall be $10.5 million and the
denominator shall be $64 million.  The Company has the option to be
released from its indemnification obligation relating to the Bank's NOL by
having the purchase price to be paid by Fourth reduced by $600,000 at the
closing.  The Company has further agreed to indemnify Fourth and Bank IV
against certain liabilities due to environmental matters relating to certain 
real estate, and such indemnification is not subject to the $1 million 
deductible and the $25 million maximum liability.

          "Required Reserve" means $2,700,000 as adjusted by the

          (including its unallocated loan loss reserve) would have

          such change in the quality of a loan shall be included in
          this calculation to the extent such change has been
          reflected in the calculation of the Tangible Book Value

          less than $25,000;

          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;

          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

obtained and in which all required waiting periods expire if such
earliest legal closing date is during the first 15 days of the

legal  closing  date  occurs  after the 15th day of a month.  The 

parties agree to exert their best efforts to cause the Closing to

          untrue statement of a material fact or omit to state a
          material fact required to be stated therein or necessary

                 any kind which are not expressly enumerated in
                 the definition of "Securities Portfolio" in
                 Section 1.1 of this Agreement other than Bank's
                 investments in the other Corporations; or

                      (12) Except as permitted or contemplated by
                 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
          use its reasonable best efforts (1) to preserve its
          business and business organization intact, (2) to keep
          available to BANK IV the services of the present 
          officers and employees of the Bank, (3) to preserve the
          good will of customers and others having business
          relations with the Bank, (4) to maintain its properties
          in customary repair, working order and condition
          (reasonable wear and tear excepted), (5) to comply in all
          material respects with all Laws applicable to it and the
          conduct of its businesses, (6) to keep in force at not
          less than their present limits all existing policies of
          insurance, (7) to make no material changes in the
          customary terms and conditions upon which it does
          business, (8) to continue its current practice of selling
          loans secured by fixed rate mortgages on a
          servicing-retained basis, (9) to duly and timely file all
          reports, tax returns, and other material documents
          required to be filed with federal, state, local and other
          authorities, and (10) unless it is contesting the same in
          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

          per share, of which 100,000 shares are issued and
          outstanding.  Prime is the owner, free and clear of all

           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.


                 h.   1993 Audit Report.  Seller shall have
          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
