          ------------------------                                            
the Closing, Seller shall deliver to Purchaser the certificates for the Shares,
together with such stock powers as will entitle Purchaser to immediate
registration of the transfer of the Shares in its name and as will convey the
Shares to Purchaser free and clear of all liens and 

 
encumbrances (other than transfer restrictions imposed by applicable securities
laws).

     1.4  Time and Place of Closing.  The closing of the transactions
          -------------------------

settlement or other resolution of the Goodwill Litigation by final judgment
subject to no further appeal, and, as further consideration for the sale of the
Shares to Purchaser, Purchaser shall pay Seller fifty percent (50%) of the "net

all other costs reasonably incurred in prosecution of the Goodwill Litigation.
Purchaser agrees to employ as counsel for prosecution of the Goodwill Litigation

may mutually agree at any time to retain other or additional counsel.

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

     (a) To the knowledge of the respective  managements of Seller and Superior,
     Superior is in compliance with all laws, rules, regulations, reporting and
     licensing requirements and orders applicable to its business or to its
     employees conducting its business (including, without limitation, all
     applicable banking laws, federal and state securities laws, and laws and
     regulations concerning discrimination, truth-in-lending, usury, fair credit

     employment practices and fair labor standards, including, without
     limitation, the Equal Credit Opportunity Act, the Fair Housing Act, and the
     Community Reinvestment Act) and with its internal policies and procedures,
     except where the failure to be in 

 
     such compliance would not individually or in the aggregate have a Material
     Adverse Effect.

     (b) Neither Seller nor Superior has received any written notification or
     communication from any agency or department of any federal or state
     government (i) asserting that Superior is not in compliance with any of the
     statutes, regulations, or ordinances which such agency or department

     Effect; (ii) threatening to revoke any license, franchise, permit or
     governmental authorization; (iii) requiring or threatening to require
     Superior, or indicating that Superior may be required to enter into a cease
     and desist order, agreement (including any capital maintenance agreement)

     Superior, including, without limitation, any restriction on the payment of

statements of Superior for the quarters ended March 31, 1997, June 30, 1997 and

regulatory accounting principles with respect to the March 31, 1997, June 30,
1997 and September 30, 1997 financial statements, subject to normal recurring
adjustments (the effect of which will not individually or in the aggregate have
a Material Adverse Effect).  Seller has delivered true and complete copies of
the Superior Financial Statements to Purchaser.  Since September 30, 1997,
Superior has not declared, set aside, made or paid any dividend or other
distribution with respect to its capital stock or otherwise purchased or
redeemed directly or indirectly any shares of its capital stock.

     3.11 No Adverse Change.  Since December 31, 1996, except (i) as
          -----------------                                         
contemplated by this Agreement or in connection with the transactions
contemplated by this Agreement; or (ii) as disclosed by Seller in any Schedule

managements of Superior and Seller, Superior has no material liabilities (and
there is no currently known basis for any action, suit, proceeding, hearing,
investigation, charge, complaint, claim, or demand (including claims relating to
lender liability of Superior) against Superior giving rise to any such material
liability), except for (i) liabilities set forth on the face of the Superior
Financial Statements (rather than in any notes thereto); (ii) liabilities which

           -----                                               

     (a) All Tax Returns required to be filed by or on behalf of Superior have
     been timely filed, or requests for extensions have been timely filed,
     granted and have not expired, for periods ending on or before December 31,

     respects.

     (b) There is no audit examination, deficiency or refund litigation or
     matter that has been raised by a taxing authority with respect to any
     previously filed Tax Returns of Superior or any prior Tax payments or
     periods that could reasonably be expected to result in a determination the
     effect of which would have a Material Adverse Effect.  All Taxes due with
     respect to completed and settled examinations or concluded litigation have
     been paid or adequately reserved for.

     (c) Superior has not executed an extension or waiver of any statute of
     limitations on the assessment or collection of any Tax due that is
     currently in effect.

     (d) Adequate provision for any Taxes due or to become due for Superior for
     any period or periods through and including September 30, 1997, has been
     made and is reflected on the September 30, 1997 financial statements
     included in the Superior Financial Statements. Deferred Taxes of Superior
     reflected in the Superior Financial Statements are adequate, subject in the
     case of interim financial statements to normal recurring year end
     adjustments.

     (e) Superior has collected and withheld all Taxes which it has been
     required to collect or withhold and has timely submitted all such collected

     requirements under the Code and any state, local or foreign laws, and the
     rules and regulations thereunder.

     (f) Superior has not made any payments, is not obligated to make any
     payments, and is not a party to any contract, agreement or other
     arrangement that could obligate it to make any payments that would be
     disallowed as a deduction under Section 280G of the Code.

 
     (g) There are no liens with respect to Taxes upon any of the assets of
     Superior.

     (h) Superior has not filed any consent under Section 341(f) of the Code

     foreign country, as defined in any applicable tax treaty or convention
     between the United States and such foreign country.

claims, liens, pledges and encumbrances ("Liens"), other than Permitted
Exceptions, to all its properties and assets whether tangible or intangible,
real, personal or mixed, reflected in the Superior Financial Statements as being
owned by Superior as of the date hereof, except for such defects in title which
would not have a Material Adverse Effect.  All buildings, and all fixtures,
equipment and other property and assets, held under leases or subleases by
Superior are held under valid instruments enforceable in accordance with their
respective terms, except where the failure to have such valid and enforceable
instruments would not have a Material Adverse Effect.

warehouseman's and carrier's liens and purchase money security interests arising
in the ordinary course of business or arising by operation of law; (ii) liens
for taxes and assessments not yet payable; (iii) liens for taxes, assessments
and charges and other claims, the validity of which Superior or Seller is
contesting in good faith; and (iv) imperfections of title, liens, security
interests, claims and other charges and encumbrances the existence of which does
not or will not have a Material Adverse Effect.

     3.15 Software.  Schedule 3.15 hereto contains a list or description by type
          --------                                                              
of all operating systems and applications  for computer  programs and data bases

such Software constitutes all the Software which is used to operate the
business of Superior as currently conducted. The owner of such Software is
identified on Schedule 3.15, and Superior has the right to use the same pursuant
to valid leases or licenses therefor.  To the knowledge of the respective
managements of

or other proprietary right of anyone else and no claim with respect to any such
infringement or violation is known to be threatened.

managements of Superior and Seller, Superior has the right to use any tradenames

the respective managements of Superior and Seller, all of the property of
Superior is in good condition and repair, except for reasonable wear and tear,

safety, ADA or other applicable  ordinances, regulations, or laws.

     Superior owns. With respect to each such parcel of owned real property
     (collectively, the "Owned Real Property"):

          (i) Superior has good and marketable title to the parcel of real
          property, free and clear of any security interest, easement, covenant,
          or other restriction, except for (A) installments of special
          assessments not yet delinquent; (B) recorded easements, covenants, and
          other restrictions which do not materially impair the current use,
          occupancy, or value of the Owned Real  Property subject thereto; (C)

          the Superior Financial Statements or incurred since September 30, 1997

          use of the land, and the Owned Real Property is not located within any
          flood plain;

          (iii)  there are no outstanding options or rights of first refusal to
          purchase any parcel of Owned Real Property, or any portion thereof or
          interest therein; and

          (iv)  there are no parties (other than Superior) in possession of the
          parcel of Owned Real Property, other than tenants in possession of
          property leased or subleased by Superior under any leases or subleases
          disclosed on Schedule 3.17(b) which tenants are in possession of space
          to which they are entitled.

     (b) Schedule 3.17(b) lists and describes briefly all real property,
     including Owned Real Property, leased or subleased by or to Superior
     (whether as lessor or as lessee) pursuant to any lease, sublease, license,

     of use or occupancy of such property ("Leased Real Property").  Superior
     has made available to Purchaser correct and complete copies of the leases
     and subleases listed in Schedule 3.17(b) (as  amended to date) .  With
     respect to each lease and sublease listed in Schedule 3.17(b), except as to
     matters which, individually or in the aggregate, will not result in a
     Material Adverse Effect:

          (i)  to the knowledge of the respective managements of Superior and
          Seller, the lease or sublease is legal, valid, binding, enforceable,
          and in full force and effect;

          Seller, no party to the lease or sublease is in breach or default, and
          no event has occurred which, with notice or lapse of time, would
          constitute a breach or default or permit termination, modification, or
          acceleration thereunder;

          (iii)  to the knowledge of the respective managements of Superior and
          Seller, no party to the lease or sublease has repudiated any provision
          thereof;

          (iv)  to the knowledge of the respective managements of Superior and
          Seller, there are no disputes, oral agreements, 

 
          or forbearance programs in effect as to the lease or sublease; and

          (v) Superior has not assigned, transferred, conveyed, mortgaged,
          deeded in trust, or encumbered any interest in the leasehold or
          subleasehold.

     (c) Schedule 3.17(c) sets forth a depreciation schedule of the fixed assets
     by asset category of Superior as of October 31, 1997.

commitments for loans and deposits entered into in the ordinary course of
business, no agreement to which Superior is a party either obligates Superior to
pay in excess of $50,000 over the life of such agreement, or is not terminable
by Superior without penalty at will or upon notice of not more than 30 days.
Superior is not, and neither Superior nor Seller has received any notice or has
any knowledge that any other party is in default in any respect under any such
agreement, except for those defaults which would not have, individually or in
the aggregate, a Material Adverse Effect, and there has not occurred any event
that with the lapse of time or the giving of notice or both would constitute
such a default.

     3.19  Benefit Plans.
           ------------- 

     (a)  Schedule 3.19(a) hereto lists all existing employee benefit plans (as
     defined in Section 3 (3) of the Employee Retirement Income Security Act of
     1974, as amended ("ERISA")), in which Employees or former employees of
     Superior currently participate (the "Plans").  Seller has provided or will
     provide to Purchaser a summary description of each Plan.

     (b) Each Plan is and has been in substantial compliance, in form and
     operation, in all material respects with all applicable laws and has been
     administered in all material respects in accordance with its terms.
     Superior has not incurred any liability with respect to a Plan including,
     without limitation, under ERISA (including, without limitation, Title I or
     Title IV of ERISA, other than liability for premiums due to the Pension
     Benefit Guaranty Corporation ("PBGC")), the Code or other applicable law,
     which has not been satisfied in full, and, to the knowledge of the
     respective managements of Seller and Superior, no event has occurred, and
     there exists no known condition or set of circumstances, which 

 
     could result in the imposition of any liability with respect to a Plan,
     including, without limitation, under ERISA (including, without limitation,
     Title I or Title IV of ERISA), the Code or other applicable law with
     respect to the Plan. To the knowledge of the respective managements of
     Superior and Seller, no event has occurred and no condition exists with
     respect to any Plan which is likely to subject Purchaser, directly or
     indirectly (through an indemnification agreement or otherwise), to any
     material liability (including, without limitation, liability for taxes,
     breach of fiduciary duty, or for a "prohibited transaction" within the
     meaning of Section 406 of ERISA or Section 4975 of the Code). There is no
     action, suit, or claim (other than routine claims for benefits in the
     ordinary course) with respect to any Plan pending or threatened which is
     reasonably likely to have a Material Adverse Effect. No Plan is currently
     under investigation or audit by any governmental agency and, to the
     knowledge of Seller's management, no such investigation or audit is
     contemplated or under consideration. Each Plan intended to be a qualified
     plan under Section 401(a) of the Code is so qualified and a favorable
     determination letter as to qualification under Section 401(a) of the Code
     has been issued and the related trust has been determined to be exempt from
     taxation under Section 501(a) of the Code.

     (c) Superior has no outstanding commitments to provide or to cause to be
     provided any severance or other post-employment benefit, salary
     continuation, termination, disability, death, retirement, health or medical
     benefit or similar benefit to any person (including, without limitation,
     any Employee or former employee) that either has not been reflected in the
     Superior Financial Statements or is not included in any Plan disclosed in
     Schedule 3.19(a).  All contributions and premium payments required to have
     been made or accrued under or with respect to any Plan have been timely
     made or accrued.  Except as set forth in Schedules 3.19(c) and 5.4(e), the
     consummation of the transactions contemplated hereby will not give rise to
     any right to severance, separation or similar pay or benefits.

     (d) Superior has never maintained, adopted or established, contributed or
     been required to contribute to, or otherwise participated or been required
     to participate in, a "multiemployer plan" (as 

 
     defined in Section 3(37) of ERISA). No amount is due as owing from Superior
     on account of a "multiemployer plan" (as defined in Section 3(37) of ERISA)
     or on account of any withdrawal therefrom.

     3.20 Employees.  Set forth in Schedule 3.20 hereto is a list of all
          ---------                                                     
employees of Superior as of the date of this Agreement (the "Employees"),
including a list of Superior's current directors.  Also set forth on Schedule
3.20 with respect to each Employee are the amount of base salary currently being
paid on an annualized basis, the amount of any raise or bonus that Superior is
currently committed to pay and the principal amount as of October 31, 1997 of
any loans or advances to such Employee by Superior.  Seller has made available
to Purchaser all written employment, severance, non-competition, and similar
agreements between Superior and Employees.

     3.21 Labor.  No material work stoppage involving Superior is pending or, to
          -----                                                                 
the knowledge of the respective managements of Superior and Seller, threatened.
Superior is not involved in, or, to the knowledge of Seller's management,
threatened with or affected by, any labor or other employment related dispute,
arbitration, lawsuit or administrative proceeding, which might reasonably be
expected to have a Material Adverse Effect.  The Employees are not represented
by any labor union, and, to the knowledge of the respective managements of
Superior and Seller, no labor union is attempting to organize employees of
Superior.

     3.22 Environmental Matters.  To the knowledge of the respective managements
          ---------------------                                                 
of Superior and Seller, neither Superior, nor any Owned Real  Properties or
Leased Real Properties, has been or is in violation of or liable under any
Environmental Law, except for such violations or liabilities that, individually
or in the aggregate, are not reasonably likely to have a Material Adverse
Effect.  There are no actions, suits or proceedings, or demands, claims, notices
or investigations (including, without limitation, notices, demand letters or
requests for information from any environmental agency) instituted or pending,
or to the knowledge of the respective managements of Superior and Seller,
threatened, relating to the liability of any such properties under any
Environmental Law, except for such violations or liabilities that, individually
or in the aggregate, are not reasonably likely to have a Material Adverse
Effect. Seller has provided Purchaser copies of Phase I audits on certain of the
Owned Real Properties which Purchaser acknowledges were not prepared for the
purposes of the transactions contemplated by this Agreement and as to which
neither Seller nor Superior makes any representations or warranties.

 
     "Environmental Law" means any federal, state, local or foreign law
     (including, without limitation, the comprehensive Environmental Response,
     Compensation and Liability Act of 1980, the Resource Conservation and
     Recovery Act of 1976 and OSHA, each as amended), statute, ordinance, rule,
     regulation, code, license, permit, authorization, approval, consent, order,
     judgment, decree, injunction or agreement with any regulatory authority
     relating to (i) the protection, preservation or restoration of the
     environment (including, without limitation, air, water vapor, surface
     water, groundwater, drinking water supply, surface soil, subsurface soil,
     plant and animal life or any other natural resource), and/or (ii) the use,
     storage, recycling, treatment, generation, transportation, processing,
     handling, labeling, production, release or disposal of any substance
     presently listed, defined, designated or classified as hazardous, toxic,
     radioactive or dangerous, or otherwise regulated, whether by type or by
     quantity, including any material containing any such substance as a
     component.

     3.23 Insurance.  Schedule 3.23 identifies each insurance policy (including
          ---------                                                            
policies providing property, casualty, liability, directors and officers
liability, and workers' compensation coverage and bond arrangements) under which
Superior is currently insured. To the knowledge of the respective managements of
Superior and Seller, with respect to Superior's coverage under each such policy,
the policy is legally valid, binding, enforceable, and in full force and effect
as of the date of this Agreement.

     3.24 Disclosure.  No representation or warranty of Seller contained in this
          ----------                                                            
Agreement or in any statement or certificate furnished or to be furnished to
Purchaser pursuant hereto in connection with the transactions contemplated
hereby contains or will contain any untrue statement of a material fact or omits
or will omit to state a material fact necessary to make the statements made
herein or therein, in the light of the circumstances under which they were made,
not misleading.

     3.25 Other Matters.  Seller has not taken and has not agreed to take any
          -------------                                                      
action, and has no knowledge of any fact or circumstances, that would materially
impede or delay the consummation of the transactions contemplated hereby.

     3.26 Brokers and Finders.  Neither Seller nor Superior nor any of their

for any financial advisory fees, brokerage fees, commissions 

 
or finder's fees, and no broker or finder has acted directly or indirectly for
Seller in connection with this Agreement or the transactions contemplated
hereby.

                    CONDUCT OF BUSINESS PRIOR TO THE CLOSING

     4.1  Conduct Prior to Closing.  Seller hereby covenants and agrees with
          ------------------------                                          
Purchaser, that, prior to the Closing, unless the prior written consent of
Purchaser shall have been obtained, which consent shall not be unreasonably
withheld, and except as otherwise contemplated in this Agreement, it shall cause
Superior and its Subsidiaries to, and Superior and its Subsidiaries shall,
operate their respective businesses only in the usual, regular and ordinary
course and in accordance with their respective prior practices, and shall use
their reasonable best efforts to preserve intact their respective  business
organizations and assets and maintain their respective rights, franchises and
businesses and customer relations necessary to run their respective businesses
as currently run, to maintain present relationships with licensors, suppliers,
distributors and others having significant business relationships with them, and
to keep available the services of their respective officers and employees.
Notwithstanding anything to the contrary contained herein, Purchaser
acknowledges that, prior to the Closing, Superior intends to sell to Seller or
one of its affiliates all of its automatic teller machines located in Wal-Mart,
Sam's Club and Wal-Mart Supercenter properties.  Without limiting the generality
of the foregoing and except as otherwise affected by matters contemplated by
this Agreement or in connection with the transactions contemplated by this
Agreement, from the date hereof until the Closing, Seller will cause each of
Superior and its Subsidiaries to, and each of Superior and its Subsidiaries
will:

     (a) carry on its business in substantially the same  manner as heretofore
     carried on and neither introduce any material new method of management,
     operation or accounting, nor provide discounted services outside the
     ordinary course of business;

     repair, ordinary wear and tear excepted;

     (c) maintain its present debt and lease instruments (unless same are
     otherwise mature), perform all of its obligations thereunder and refrain

     in the ordinary course of business, without prior written notice to
     Purchaser;

     (d) not incur any indebtedness outside of the ordinary course of business
     other than deposits or ordinary trade accounts payable at market rates with
     no prepayment penalty which are used to fund operations in the ordinary
     course of business;

     (e) keep in full force and effect its present insurance policies or other
     comparable insurance coverage;

     (f) maintain its present salaries and commission levels for all officers,

     ordinary course of its business, refrain from entering into employment
     agreements except in the ordinary course of business, and refrain from

                             ADDITIONAL AGREEMENTS

     5.1  Current Information.  During the period from the date of this
          -------------------                                          
Agreement to the Closing Date, each of Seller and Purchaser will cause one or
more of its representatives to confer on a regular and frequent basis with
representatives of the other with respect to the status of the ongoing
operations of Superior.  Each party will notify the other of the status of any
required regulatory applications and third-party consents related to the
transactions contemplated hereby.

     5.2  Access; Information.
          ------------------- 

     (a) During the period from the date of this Agreement to the Closing Date,
     Seller shall, upon reasonable notice, cause Superior to afford to Purchaser
     and its representatives (including, without limitation, officers and
     employees of Purchaser and counsel, accountants and other professionals
     retained by Purchaser), such access during normal business hours to its
     books, records, properties and such other information as Purchaser may
     reasonably request for the purpose of conducting any review or
     investigation reasonably related to the transactions contemplated hereby,
     provided that such access shall not interfere with the normal business
     operations of Superior.

     (b) Purchaser agrees that it will keep confidential any information
     furnished to it in connection with the transactions contemplated by this
     Agreement in accordance with the terms of the Confidentiality Agreement
     dated August 12, 1997 between 

 
     Seller and Purchaser, as amended by letter dated November 24, 1997 (the
     "Confidentiality Agreement"), which agreement shall remain in effect in
     accordance with its terms.

     5.3  Regulatory Matters.  Purchaser shall use its reasonable best efforts
          ------------------                                                  
(i) to prepare all documentation, to effect all filings and to obtain all
permits, consents, approvals and authorizations of all third parties, regulatory
authorities and other governmental authorities necessary to consummate the
transactions contemplated by this Agreement, including, without limitation, any
such approvals or authorizations required by any state or regulatory authority,
including, without limitation, the Board of Governors of the Federal Reserve
System (the "Federal Reserve"), the OTS, and any state insurance commissioner;
and (ii) to cause the transactions contemplated hereby to be consummated as
expeditiously as reasonably practicable.  Provided that Seller has cooperated
with Purchaser in providing information necessary to the completion of requisite
applications, Purchaser agrees to file the requisite applications to be filed by
it with any required regulatory authorities no later than 45 days after the date
of this Agreement.

     5.4  Employee Benefits and Other Matters.
          ----------------------------------- 

     (a) Purchaser will continue to employ Employees on an "at will" basis.
     Seller shall remain responsible for the payment of any benefit accrued by
     Employees prior to the Closing Date under any severance, salary
     continuation, incentive or similar agreement between Superior and/or Seller
     and any Employees entered into prior to the Closing Date.

     (b) Effective as of the Closing Date, Seller shall cause Superior to
     withdraw from participation in, and Employees shall cease accruing benefits
     under, all of Seller's employee benefit plans and policies.  On or before
     the Closing Date, Seller or Superior, as the case may be, shall, to the
     extent permitted under applicable law, cause Employees participating in any
     qualified defined benefit pension Plan or qualified defined contribution
     Plan to become fully vested under the terms of such Plans. Seller shall
     amend its defined contribution Plan to provide that Employees shall be
     eligible to receive the employer matching contribution for the year in
     which the Closing Date occurs without regard to the requirement that a
     participant be employed by Seller on December 31 of such year.  Purchaser
     shall, as soon as practicable after the Closing Date, establish a
     retirement plan which Purchaser deems reasonable and competitive among
     employers in the markets where 

 
     Purchaser will conduct business. For the purposes of such plans established
     by Purchaser, prior continuous service of Employees with Superior or Seller
     shall be counted as continuous service with Purchaser for satisfaction of
     enrollment, eligibility and vesting requirements. Seller remains
     responsible for all benefits accrued by Employees as of the Closing Date
     resulting from participation in Seller's defined benefit and defined
     contribution Plans.

     (c) On the Closing Date, Purchaser will have established and will make
     available to Employees reasonable and competitive employee welfare plans,
     including, without limitation, medical, life and disability plans, and will
     use its best efforts to enroll all participating Employees in such plans
     without consideration of pre-existing conditions. Purchaser will also use
     its best efforts to permit plan-year payments toward satisfaction of
     participant deductible amounts and other employee payment limits to carry
     forward to the plan established by Purchaser. Plan design and premium
     distribution under such plan or plans will rest solely with Purchaser.
     Purchaser and Seller agree that liability for medical claims of Employees
     incurred but unpaid before the Closing Date shall remain with Seller.
     Seller shall offer retiree medical coverage and retiree medical
     reimbursement account benefits to Employees eligible for such benefits as
     of the Closing Date and liabilities for such coverage shall remain with
     Seller.  Purchaser will provide such other insured and uninsured welfare
     plans as it deems appropriate. With respect to such plans, continuous
     service of Employees with Superior will be counted as continuous service
     with Purchaser for satisfaction of enrollment and other eligibility
     requirements of such plans and for determining eligibility for vacation,
     personal leave and other similar employee benefit and recognition programs
     which Purchaser may implement.  As of the Closing Date, Purchaser shall
     have established a health care reimbursement plan and a dependent care
     reimbursement plan, and  Seller shall transfer the balances in its health
     care reimbursement fund and dependent care reimbursement fund to the extent
     of unused Employee accounts in such plans to Purchaser's plans.  To the
     extent a participant's health care reimbursement account has a negative
     account balance as of the Closing Date, Purchaser will continue to
     administer its medical reimbursement plan and withhold amounts from such
     participant's paychecks in accordance with the Employee's election, and if
     such participant has a positive account balance in Purchaser's health care
     reimbursement fund following the close of 

 
     all claims for the year in which the Closing occurs, Purchaser shall
     transfer such positive amounts to Seller.

     (d) Seller makes no representations or warranties about whether any
     Employees will remain employed by Superior after the date of this
     Agreement. Seller will use its best efforts to maintain the Employees as
     employees of Superior until the Closing Date.

     (e) Purchaser agrees that, for a period of six (6) months after the Closing
     Date, it will not terminate without "good cause" (as defined in Schedule
     5.4(e)) a transferred Employee without paying to such Employee a severance
     benefit no less than the applicable severance benefit set forth on Schedule
     5.4(e).

     5.5  Certain Tax Matters.  Seller and Purchaser hereby covenant and agree
          -------------------                                                 
with respect to certain tax matters as follows:

     (a) The NationsBank Group, or a successor common parent, and Purchaser
     shall jointly make a timely Section 338(h)(10) Election in accordance with
     federal and applicable state Tax Laws and as set forth herein.  Seller and
     Purchaser will supply in advance to one another copies of all
     correspondence, filings or communications (or memoranda setting forth the
     substance thereof) to be sent or made by Seller or Purchaser or their
     respective representatives to or with the IRS or any other Governmental
     Entity relating to such election.  Seller and Purchaser agree to report the
     transfers under this Agreement consistent with such Section 338(h)(10)
     Election and shall take no position or action contrary thereto.

     (b)  (i)  Seller and Purchaser shall be jointly responsible for the
          preparation and filing of all Section 338 Forms to be prepared by them
          in accordance with applicable Tax Laws and the terms of this
          Agreement, and each party shall deliver to the other party such Forms
          and related documents as soon as practicable prior to the date such
          Section 338 Forms are required to be filed under applicable Tax Laws.
          As soon as practicable after the Closing Date, Seller and Purchaser
          shall jointly prepare a schedule calculating the "modified aggregate
          deemed sale price" for the deemed sale of assets under Section 338 of
          the Code and showing an allocation of that amount among the assets of
          Superior in accordance with the regulations thereunder.  Any such
          agreed allocation 

 
          shall be binding upon Seller, Purchaser and their respective
          affiliates unless a different allocation is required pursuant to a
          determination within the meaning of Section 1313 of the Code.

          (ii) Seller and Purchaser shall reduce such allocation to writing,
          including jointly and properly executing necessary copies of completed
          Section 338 Forms.  Seller and Purchaser shall file timely any such
          Section 338 Forms with the IRS.

          (iii) To the extent consistent with applicable law, Seller and
          Purchaser shall not file any Tax Return or other documents or
          otherwise take any position with respect to Taxes which is
          inconsistent with such allocation of the "modified aggregate deemed
          sale price", provided, however, that neither Seller nor Purchaser
          shall be obligated to litigate any challenge to such allocation of the
          Purchase Price by a Taxing Authority.

          (iv) Seller and Purchaser shall promptly inform one another of any
          challenge by any government body to any allocation made pursuant to
          this Section 5.5(b) and agree to consult with and keep one another
          informed with respect to the status of, and any discussion, proposal
          or submission with respect to, such challenge.

     (c) Seller shall pay and shall indemnify and hold Purchaser harmless
     against any and all Taxes of Superior or Seller for any Taxable Period
     ending on or before the Closing Date, including any Taxes resulting from
     the making of the Section 338(h)(10) Election, and any liability for Taxes
     pursuant to Treasury Regulation Section 1.1502-6; in each case, after
     giving effect to any credits for the amount of Tax, if any, paid on or
     prior to the Closing Date. The indemnification provided herein is separate
     from and in addition to the indemnification provided in Section 8.1 hereof
     and is not subject to any minimum or maximum amount in such section.  All
     liabilities and obligations between Superior, on the one hand, and Seller
     and any of Sellers' affiliates, on the other hand, under any Tax allocation
     agreement or arrangement in effect on or prior to the Closing Date (other
     than this Agreement or as set forth herein) shall cease to exist as of the
     Closing Date.

 
     (d) Purchaser shall be liable for, shall pay and shall indemnify and hold
     Seller harmless against, any and all Taxes of Superior for any taxable year
     or Taxable Period commencing after the Closing Date.  Purchaser shall be
     liable for, and Purchaser agrees to indemnify Seller and its affiliates
     against, any and all liability for Taxes arising, directly or indirectly,
     from a liquidation, merger, sale or other disposition of assets of Superior
     (other than in the ordinary course of business), or from any income
     otherwise recognized by Superior, on or subsequent to the Closing, other
     than Taxes resulting from the Section 338(h)(10) Election.  The
     indemnification provided herein is separate from and in addition to the
     indemnification provided in Section 8.1 hereof and is not subject to any
     minimum or maximum amount in such section.

     (e) Any Taxes for a Taxable Period beginning before the Closing Date and
     ending after the Closing Date (the "Straddle Period") with respect to
     Superior (other than the consolidated Tax Returns described in paragraph
     (f)) shall be apportioned between the portion of such period ending on the
     Closing Date (the "Pre-Closing Straddle Period") and the portion of such
     period beginning on the date following the Closing Date (the "Post-Closing
     Straddle Period") based upon the interim closing of the books for Superior
     as of the Closing Date (except that ad valorem Taxes and other Taxes not
     based upon income or receipts will be apportioned to the Pre-Closing
     Straddle Period based upon the number of days covered by such payment which
     are on or before the Closing Date and total number of days covered  by the
     payment).  For purposes of this Section 5.5, each portion of such period
     shall be deemed to be a Taxable Period.  Seller shall be responsible for
     all Taxes of Superior apportioned to the Pre-Closing Straddle Period, and
     Purchaser shall be responsible for all Taxes of Superior apportioned to the
     Post-Closing Straddle Period.  With respect to any Taxes for the Pre-
     Closing Straddle Period which are payable by Superior (other than the
     consolidated Tax Returns described in paragraph (f) and for which the
     applicable Tax Return is a Post Return (as defined below)), upon agreement
     by Purchaser and Seller as to the form and substance of such Tax Return,
     but not later than ten business days prior to the due date for the payment
     of such Pre-Closing Straddle Period Taxes, Purchaser shall present Seller
     with a copy of such Tax Return indicating the Pre-Closing Straddle Period
     Taxes payable with respect thereto and a schedule detailing the amount of
     such Taxes shown as due on such Tax Return which are in excess of the
     amount of any estimated Tax payments made with 

 
     respect to these Taxes on or prior to the Closing Date and within ten
     business days after Purchaser presents Seller with such Return, Seller
     shall pay to Purchaser the amount due. In the event Seller disputes,
     pursuant to paragraph (k), Purchaser's computation and if, upon such
     resolution, it is determined that any of such disputed amount was not
     payable to Purchaser and such amount has been paid to Purchaser, then
     Purchaser shall refund to Seller such amount, plus interest at the Federal
     Funds Rate.

     (f) Seller shall cause to be included in the consolidated federal income
     Tax Returns (and the state income Tax Returns of any state that permits
     consolidated, combined or unitary income Tax Returns, if any) of the
     NationsBank Group for all periods ending on or before or which include the
     Closing Date, all taxable income, gain, loss, deduction and credit of
     Superior which are required to be included therein, including any liability
     for Taxes resulting from the making of the Section 338(h)(10) Election,
     shall file timely all such Tax Returns with the appropriate taxing
     authorities and shall pay timely all Taxes due with respect to the periods
     covered by such Tax Returns.  Prior to the Closing Date, Superior shall pay
     to Seller all amounts for current or deferred federal and state Tax
     liability.  Seller shall prepare and file or cause Superior to prepare and
     file all Tax Returns (other than consolidated, combined or unitary, Tax
     Returns), reports and forms for Superior which are due prior to the Closing
     Date, and shall pay all Taxes or shall cause Superior to pay all Taxes set
     forth on such Tax Returns.  Purchaser, in consultation with Seller, shall
     prepare all Tax Returns (other than consolidated, combined or unitary,  Tax
     Returns) due after the Closing Date with respect to taxable periods ending
     on or before the Closing Date ("Post Returns") in a manner consistent with
     Superior's prior practices, except for changes necessary to comply with
     changes in, or application of, Tax Law.  Seller shall have the right to
     review and comment on and consent to the form and substance of such Post
     Returns.  Upon agreement with respect to the form and substance of a Post
     Return, Seller shall pay to Superior the amount of Taxes due and Purchaser
     will cause such Post Return to be timely filed.  If Purchaser does not
     prepare and timely submit a Post Return, Seller shall have the right to
     prepare and file (or cause to be prepared and filed) such Post Return in a
     manner consistent with Superior's prior practices, except for changes
     necessary to comply with changes in, or application of, Tax Law and shall
     be subject to the review and 

 
     comment on and consent to by Purchaser, which consent shall not be
     unreasonably withheld.

     (g) Seller shall have exclusive control over any dispute with any Taxing
     Authority relating to any Tax liability or Tax Return of Seller or any
     affiliate of Seller (including Superior for periods prior to the Closing
     Date) filed by the NationsBank Group, Seller or Superior for or with
     respect to any Taxable Period, or partial period, ending on or prior to the
     Closing Date, including Post Returns and other Tax Returns described in
     Section 5.5(f); provided that Seller shall keep Purchaser informed of the
     progress of any such dispute with respect to Superior.  Purchaser shall
     cooperate and shall cause its affiliates to cooperate with Seller and its
     affiliates in connection with any and all such disputes and will execute
     all lawful, true and correct powers-of-attorney, affidavits, and other
     papers necessary in connection therewith, and will provide Seller
     reasonable access during normal business hours to the employees and
     business, financial and Tax records or other similar information of
     Superior relating to such dispute.

     (h) Purchaser and Superior shall have exclusive control over any dispute
     with any Taxing Authority relating to any Tax liability or Tax Return of
     Purchaser or Superior filed for or with respect to any Taxable Period (or
     portion thereof) beginning on or after the Closing.  Seller shall cooperate
     and shall cause its affiliates to cooperate with Purchaser and its
     affiliates in connection with any and all such disputes and will execute
     all lawful, true and correct powers-of-attorney, affidavits, and other
     papers necessary in connection therewith, and will provide Purchaser and
     Superior reasonable access during normal business hours to the employees
     and business, financial and Tax records or other similar information of
     Seller and its affiliates to the extent relating to such dispute.

     (i) Purchaser shall cause Superior to elect, where permitted by law, to
     carry forward any net operating loss, charitable contribution or other item
     arising after the Closing Date that could, in the absence of such an
     election, be carried back to a Taxable period of Superior ending on or
     before the Closing Date in which Superior filed a consolidated, combined or
     unitary Tax Return with Seller or any of its affiliates.  Purchaser, on its
     own behalf and on behalf of its Tax Affiliates, hereby waives any right to
     use or apply any net operating loss, net capital loss, charitable
     contribution or 

 
     other item of Superior for any Tax year ending on any date following the
     Closing Date to part or all of the period prior to the Closing Date.

     (j) As soon as practicable, but in any event within fifteen days after
     Seller's or Purchaser's request, as the case may be, Purchaser shall
     deliver to Seller, or Seller shall deliver to Purchaser, as the case may
     be, such information and other data relating to the Tax Returns and Taxes
     of Superior and shall make available such knowledgeable employees of
     Seller, Purchaser, Superior or any of their affiliates, as the case may be,
     as Seller or Purchaser, as the case may be, may reasonably request,
     including providing the information and other data customarily required by
     Seller or Purchaser, as the case may be, to cause the completion and filing
     of all Tax Returns for which it has responsibility or liability under this
     Agreement or to respond to audits by any Taxing Authority with respect to
     any Tax Returns or Taxes for which it has any responsibility or liability
     under this Agreement or to otherwise enable Seller or Purchaser, as the
     case may be, to satisfy its accounting or Tax requirements.

     (k) If Seller and Purchaser disagree as to the amount of Taxes for which
     either of them is liable to the other under this Section 5.5, Seller and
     Purchaser shall promptly consult each other in an effort to resolve such
     dispute.  If any such point of disagreement cannot be resolved within
     fifteen days of the date of consultation, the Independent Accounting Firm
     shall act as an arbitrator to resolve all points of disagreement concerning
     Tax matters with respect to this Agreement.  All fees and expenses relating
     to the work performed by the arbitrator in accordance with this Section
     5.5(k) shall be borne equally by Seller, on the one hand, and Purchaser, on
     the other hand.

     (l) Seller and Purchaser shall (i) each give the other prompt written
     notice of the receipt of any claim by any Taxing Authority that, if
     successful, may result in an indemnity payment pursuant to this Section 5.5
     and (ii) each transmit to the other a written description reasonably
     detailing the nature of the claim, a copy of all papers served with respect
     to such claim and the basis of its claim for indemnification under this
     Section 5.5.

     (m) Purchaser shall be responsible for, and shall pay when due and payable,
     all recording, transfer and other similar taxes and 

 
     fees payable as a result of the filing or recording of any document or
     instrument of conveyance or transfer contemplated by this Agreement.

     5.6  Press Releases.  Prior to the public dissemination of any press
          --------------                                                 
release or other public disclosure of information related to this Agreement or
the transactions contemplated hereby, Purchaser and Seller shall mutually agree
as to the form, substance and timing of such release or disclosure.
Notwithstanding the foregoing, the parties may make such disclosures as are
required by law after making reasonable efforts under the circumstances to
consult in advance with the other party.

          ---------

assigns of any of the foregoing (the "Purchaser Indemnified Parties") from and
against any and all Losses (as defined below) incurred by or asserted against
any of such parties in connection with or arising out of any breach by Seller of
any representation or warranty, or any failure by Seller to comply with any
covenant or agreement set forth herein, except as provided in Section 5.5(c);
provided, however, that (i) the Purchaser Indemnified Parties shall be entitled
to indemnification under this Section 8.1 only if and to the extent their
aggregate amount of Losses hereunder (notwithstanding limitations on materiality
contained in Seller's representations and warranties) exceeds $250,000, and then
only to the extent of such excess; (ii) the Purchaser Indemnified Parties shall
not be entitled to indemnification for any Losses resulting from or incurred in
connection with the Private Placement or the Debt Offering; and (iii) in no
event shall Seller's aggregate liability hereunder exceed $5,000,000.

Until the first anniversary of the Closing Date, Purchaser shall indemnify and
hold harmless Seller, and its directors, officers, employees and agents, and
each of the heirs, executors, successors, and assigns of any of the foregoing
(the "Seller Indemnified Parties") from and against any and all Losses (as
defined below) incurred by or asserted against any of such parties in connection
with or arising out of any breach by Purchaser of any representation or
warranty, or any failure by Purchaser to comply with any covenant or agreement
set forth herein, except as provided in Section 5.5(d); provided, however, that
the Seller Indemnified Parties shall be entitled to indemnification under this
Section 8.1 only if and to the extent their aggregate amount of Losses hereunder
(notwithstanding limitations on materiality contained in Purchaser's
representations and warranties) exceeds $250,000, and then only to the 

 
extent of such excess; and provided further, however, that in no event shall
Purchaser's aggregate liability hereunder exceed $5,000,000.

"Losses" means, with respect to any of Purchaser, Seller or Superior, any and
all losses, liabilities, claims, damages, obligations (including those arising
out of any action, such as any settlement or compromise thereof or judgment or
award therein), and any reasonable out-of-pocket costs and expenses (including
reasonable attorneys' fees and expenses incurred in defending any lawsuit or
other action).

     8.2  Claims.
          ------ 

     (a) The party being indemnified hereunder (the "Indemnified Party") shall
     give written notice to the party against whom a claim for indemnification
     is asserted hereunder (the "Indemnifying Party") within the earlier of
     twenty (20) days of receipt of written notice or forty (40) days from
     discovery by the Indemnified Party of any matters which may give rise to a
     claim for indemnification or reimbursement under this Agreement (a
     "Claim").  The failure to give such notice shall not affect the right of
     the Indemnified Party to indemnity hereunder unless such failure has
     materially and adversely affected the rights of the Indemnifying Party.

     (b) In the event an action brought by a third party (a "Third-Party Claim")
     shall be brought or asserted in respect of which indemnity may be sought by
     an Indemnified Party under this Section 8.2,  the Indemnified Party shall
     notify the Indemnifying Party in writing thereof within such period of time
     as to not prejudice the defense thereof, but in any case within twenty (20)
     days thereof.  Subject to this Section 8.2, the Indemnifying Party shall
     have the opportunity to defend and/or settle such Third-Party Claim, and
     employ counsel reasonably satisfactory to the Indemnified Party, and the
     Indemnifying Party shall pay all expenses related thereto, including,
     without limitation, all fees and expenses of counsel.  After receipt of
     such notice, the Indemnifying Party shall notify the Indemnified Party
     within twenty (20) days (or such shorter period if necessary so as not to
     prejudice the defense thereof) in writing whether it will assume the
     defense thereof.

     (c) Upon receipt of notice by the Indemnified Party from the Indemnifying
     Party of its election to assume the defense of such an action and approval
     of the Indemnified Party of counsel to the Indemnifying Party, which
     approval shall not be unreasonably 

 
     withheld or delayed, the Indemnifying Party shall not be liable to the
     Indemnified Party for any legal or other expense subsequently incurred by
     the Indemnified Party unless (i) the Indemnifying Party agrees in writing
     to pay such fees and expenses, (ii) the Indemnifying Party fails either to
     assume the defense of such action or to employ counsel reasonably
     satisfactory to the Indemnified Party, or (iii) the Indemnified Party shall
     have been advised by counsel that there may be one or more legal defenses
     available to the Indemnified Party that are different from or in addition
     to those available to the Indemnifying Party or that there shall exist some
     other legal conflict between the interests of the Indemnifying Party and
     the Indemnified Party.

     (d) If the Indemnifying Party shall not elect to assume the defense of any
     Third-Party Claim, or if any of the events specified in clauses (i) through
     (iii) in the preceding subsection (c) occurs, the Indemnified Party shall
     have the right to maintain the defense of and to settle such Third-Party
     Claim, with counsel reasonably satisfactory to the Indemnifying Party;
     provided, however, that the Indemnifying Party shall retain the right to
     assume the defense of such Third-Party Claim pursuant to paragraph (c)
     above, provided that such assumption does not prejudice the defense of such
     Third-Party Claim.

     (e) In the event that an offer to settle a Third-Party Claim is received,
     each of the Indemnified Party and the Indemnifying Party shall notify the
     other thereof, in writing, and shall consult with one another in
     considering such offer.  Such offer shall be accepted if the Indemnifying
     Party so directs in writing unless either (A) the Indemnified Party shall
     agree in writing that any liability arising out of such Third-Party Claim
     shall not be a Loss covered hereunder, in which case the Indemnified Party
     shall have full right to maintain the defense thereof, or (B) the failure
     to accept such settlement offer is based on the Indemnified Party's
     reasonable objection to a sanction, restriction, fine, or other penalty
     that would be imposed on it or its affiliates under the settlement.

     (f) Notwithstanding anything herein, and whichever party shall have the
     right to maintain the defense of a Third-Party Claim, each of the
     Indemnifying Party and the Indemnified Party shall consult with the other
     with respect thereto, provide each other with such assistance as the other
     may reasonably require in order to 

 
     promptly and adequately defend such action, and have the right to
     participate at its own expense in the defense thereof, with counsel
     reasonably satisfactory to the other.

     8.3  Survival.  The representations, warranties, covenants and agreements
          --------                                                            
of each party set forth herein shall survive the Closing for a period of one (1)
year.  Neither party hereto shall have any liability (for indemnification or
otherwise) with respect to any representation, warranty, covenant or agreement
set forth herein, unless on or before the first anniversary of the Closing Date
the other party shall notify such party of a claim specifying the factual basis
of that claim in reasonable detail.

     transactions contemplated hereby of any representation, warranty, covenant
     or agreement by Purchaser contained herein which has not been, or cannot
     be, cured within 30 days after written notice of such breach or failure to
     perform is given to Purchaser; or

     (d) by any party, following ten (10) days' written notice to the other
     parties, if, at any time prior to the Closing Date any event shall have
     occurred or facts and circumstances shall exist that render any of the
     conditions to such party's obligations as provided in this Agreement
     incapable of fulfillment unless caused by the breach of any covenant or
     agreement under this Agreement by the terminating party; or

 
     (e) by any party upon notice to the other parties if the Closing has not
     taken place on or before November 30, 1998; or

     (f) by Seller or Superior, in its sole discretion, if Purchaser shall not
     have done any of the following:  (i) by January 15, 1998, received firm
     commitments for $95.0 million in connection with the Private Placement; or
