         or similar instrument, except for deposit liabilities incurred in the
         ordinary course of business pursuant to the Seller's customary rate
         schedules, and except for other liabilities and obligations incurred in
         the ordinary course of business;

                  (ii) The Seller shall not sell, transfer, mortgage, encumber
         or otherwise dispose of any of the Assets except for the disposition of
         Assets (other than the Real Estate, Improvements or Leasehold
         Improvements) in the ordinary course of business;

                  (iii) Except as provided in Article 6, the Seller will not
         cause the transfer from one or more of the Branches to the Seller's
         other operations (except to another Branch) of any deposits of the type
         included in the Liabilities; provided, however, that the Seller may
         transfer deposits to the Seller's other branches or offices upon
         request of the depositors and may transfer to its other branches or
         offices other deposits which are not to be transferred to Buyer
         pursuant to this Agreement;

                  (iv) The Seller shall not make any capital commitments with

         Facility, and (B) emergency repairs required to restore any Facility to
         a safe operating condition;

                  (v) The Seller shall not grant any increase in the rate of
         compensation or in the benefits payable or to become payable to any
         current officer or employee of the Facilities, or to any current agent
         or consultant thereof, over the levels in effect as of the date hereof,
         other than any regularly scheduled increases, including bonuses,
         contemplated under contracts, policies or programs existing on the date
         hereof or under any benefit program generally applicable to the
         Seller's employees; provided that the Seller shall retain the right to
         hire additional Branch and Office employees at comparable rates of
         compensation as necessary for the operation of the Facilities;

                  (vi) The Seller will maintain the Real Estate, Leased Real
         Estate, Improvements, Leasehold Improvements and Furniture, Fixtures
         and Equipment substantially in accordance with its normal practices,
         and keep such property in its present condition, ordinary wear and tear
         excepted;

                  (vii) The Seller shall operate the Facilities and the
         businesses thereof in accordance with Seller's normal practices and
         will use reasonable efforts to preserve for the benefit of the Buyer
         after the Closing the Facilities' business, goodwill and relationships
         (including deposit relationships at the Facilities) with customers and
         suppliers; without limiting the generality of the foregoing, Seller
         will not, and, following the closing of the BankAmerica/NationsBank
         Business Combination, Seller will not permit the New Mexico operations
         of NationsBank, N.A., to:

                  (A)      Solicit deposits, deposit-related products or loans
                           from persons who are depositors at the Facilities,
                           except in connection with general solicitations or
                           general advertising not targeted specifically at the
                           depositors at the Facilities and except non-targeted
                           solicitations or advertising in the ordinary course
                           of providing service to individual depositors at the
                           Facilities who are also at the time of such
                           solicitation or advertisement depositors of other

                           solicitations of individual depositors at the
                           Facilities in the ordinary course of providing
                           service to such depositors undertaken without
                           management direction given from and after the date of
                           this Agreement;

                  (C)      Introduce at any of the Facilities any new deposit
                           product or change any feature of any deposit product
                           except a new product or feature introduced throughout
                           Seller's offices region-wide in the ordinary course
                           of business; and

                  (viii) The Seller shall provide the Buyer reasonable access
         during normal business hours to, and the opportunity to review and
         inspect, the Real Estate, Improvements, Leased Real Estate, Leasehold
         Improvements, Furniture, Fixtures and Equipment, and the Records; shall
         furnish to the Buyer such reports and compilations pertaining thereto
         as the Buyer shall reasonably request from time to time (provided that
         the Seller shall have no obligation to assemble any new reports or
         compilations not already prepared in the ordinary course of the
         Seller's business); and shall furnish to the Buyer all such other
         information pertaining to the Assets and the Liabilities and the
         business of the Facilities as the Buyer may reasonably request. In no
         event, however, shall the Seller be obligated to incur any fees or
         expenses (including accounting or other professional fees) other than
         the indirect costs associated with the employment of the Seller's
         existing employees in connection with the furnishing of any such
         information or reports. In addition, the Seller shall provide the Buyer
         reasonable access to the Facilities during the thirty (30) calendar day
         period immediately preceding the Closing Date for the purpose of
         installing teller terminals and other equipment, provided that (A)
         Seller shall not be required to provide such access to any Facility
         until after all consents, approvals and authorizations referred to in
         Sections 7.1(c) and 7.2(c) hereof have been obtained with respect to
         all Facilities and (B) Buyer shall give Seller at least twenty-four
         (24) hours advance notice that it wishes to have such access. The Buyer
         agrees to cause the installation of such teller terminals and other
         equipment to be effected in a manner intended to minimize disruption to
         the operations of the Facilities.

         (b) Buyer's Access to Facility Premises. The Buyer will indemnify,
defend, and hold Seller harmless for, from and against any and all claims,
damages, costs, liabilities and

losses (including mechanics' liens) arising out of any entry by Buyer or its
agents, designees or representatives on the Real Estate or Leased Real Estate
for purposes of the review, inspection and installation provided for in Section
2.3(a)(viii) or for any other purpose (other than for the purposes set forth in
Section 4.4(c), which shall be governed by the provisions of that Section).
Without limiting the scope of the foregoing, Buyer also will restore the Real
Estate, Improvements, Leased Real Estate, Leasehold Improvements, Furniture,
Fixtures and Equipment, and Records at its sole cost and expense if one or more
of the transactions contemplated by this Agreement do not close. Until
restoration is complete, Buyer will take all steps necessary to ensure that any
conditions at the Facilities created by any testing, review, inspection,
installation or other actions performed by or for Buyer will not interfere with
the normal operation of the Facilities or create any dangerous, unhealthy,
unsightly or noisy conditions at the Facilities. Buyer shall comply with any
requirements or restrictions contained in the Leases regarding any actions it
takes at the Leased Real Estate, including, without limitation, any requirements
of notice to the landlord (all of which notices at any time prior to Closing
will be made through Seller or Seller's agent). The provisions of this Section
2.3(b) shall survive the Closing or any earlier termination of this Agreement.

         (c) Data Processing Conversion. The conversion of the data processing
with respect to the Facilities and the Assets and the Liabilities to be
transferred hereunder will be completed no later than the next Business Day
following the Closing Date. In connection with the data processing conversion,
the Seller and the Buyer shall each pay its own costs and expenses associated
with the data processing conversion and shall bear equally the duties and
responsibilities relating to such conversion. The Seller will use its reasonable
efforts to have available to the Buyer at a mutually agreed date and time after
the Closing Date, a list (which may be in the form of machine-readable data
cartridges) of the Assumed Deposits as of the most recent practicable date,
which list identifies each Assumed Deposit by type, with appropriate information
regarding the depositor and the terms of the Assumed Deposit. The Buyer will
have the responsibility of arranging and paying for courier pick-up of such
information from the Seller's data processor in Milwaukee, Wisconsin and
delivery to the Buyer's data processor. In no event shall the Seller be required
to provide any computer programming, source code or changes in existing file
layouts. The Seller will not migrate (transfer) existing PINs used for ATM cards
to the Buyer.

         2.4 Employee Considerations

         (a) Buyer shall offer employment as of the day after the Closing Date
to all Employees described on Schedule 1.1(a)(1). Buyer shall have the
opportunity to interview Employees 


                                      -18-

BRANCH PURCHASE AGREEMENT

   23


described on Schedule 1.1(a)(2) and may offer employment as of the day after the
Closing Date to any such Employee. All Employees shall be offered employment at
base wages and salaries no less favorable than the wages and salaries currently
being paid by Seller to such Employees. To the extent consistent with Buyer's
existing structure for comparable positions and comparable officer titles and
its current policies regarding officer titles, Employees shall be offered
positions with responsibilities and officer titles comparable to those they
currently have with Seller. Unless agreed upon by an Employee, the position
offered by the Buyer will not create a commute that is greater than 35 miles one
way, and if the Employee's current commute is in excess of 35 miles one way, the
position will not increase the Employee's commute.

         (b) All Employees who accept employment with Buyer as of the day after
the Closing Date shall be eligible to participate in the employee benefit plans
and other fringe benefits of Buyer on the same basis as such plans and benefits
are offered to employees of Buyer with comparable positions with Buyer, except
as provided in the penultimate sentence of Section 2.4(e). Buyer shall credit
such Employees for their length of service with Seller or its Affiliates for all
purposes under each employee benefit plan and fringe benefit to be provided by
Buyer to such Employees, to the same extent such service was recognized under a
similar plan of Seller, based on information provided by Seller. However, such
service need not be counted for purposes of calculating accrued benefits under a
pension benefit plan, except that in determining the rate of prospective benefit
accrual, service shall be counted where such rate increases with service. For
purposes of this Section 2.4, "employee benefit plans and other fringe benefits"
includes, without limitation, pension and profit sharing plans, retirement and
post retirement welfare benefits, health insurance benefits (medical, dental and
vision), disability, life and accident insurance, sickness benefits, vacation,
employee loans and banking privileges.

         (c) If Buyer offers a salary continuation or similar program for
employees unable to work for medical reasons, the Employees who accept
employment with Buyer shall be credited under any program of Buyer with at least
the number of sickness benefit days accrued under Seller's program at the
Closing Date.

         (d) Seller agrees to remain responsible for the payment of all benefits
accrued during the period of employment by the Seller under the terms of the
Seller's retirement plans with respect to any Employee. Buyer shall not at any
time assume any liability for the benefits of any active or any terminated,
vested or retired participants in the Seller's retirement plans.

         (e) Seller shall be responsible for payments for accrued vacation not
taken by an Employee on or prior to the Closing


                                      -19-

   24


Date and for timely payment as required by law of all wages, salaries, bonuses,
if any, and other compensation with respect to service completed on or prior to
the Closing Date. Seller shall offer Employees who accept employment with Buyer
the option to receive cash or to transfer to Buyer their accrued vacation days
or fractions thereof earned but unused while employed by Seller. In the event
any Employee elects to receive cash upon employment by Buyer, Seller shall make
a cash payment to such Employee in accordance with applicable law. In the event
any such Employee elects to have his or her accrued vacation transferred upon
employment by Buyer, Buyer shall give such Employee credit after the Closing
Date for the same number of vacation days or fractions thereof he or she has
accrued with Seller as of the Closing Date. For purposes of this Section 2.4(e),
personal choice days or fractions thereof will be treated as vacation days. In
the event Employees elect to have their accrued vacation carried over to Buyer,
Seller shall pay to Buyer, not later than the date of the Final Financial
Statement, an amount equal to the net cash value of each such Employee's accrued
vacation before payroll deductions. In the calendar year in which the Closing
Date occurs, Employees shall be eligible to earn at least the prorated annual
vacation amount Employees were eligible to earn under Seller's vacation policy.
In subsequent calendar years, Employees will be eligible to earn vacation
according to the schedule specified in Buyer's policy.

         (f) Seller shall retain the responsibility for payment of all medical,
dental, vision, health and disability claims incurred by any Employee on or
prior to the Closing Date, and Buyer shall not assume any liability with respect
to such claims. After the Closing Date, all medical, dental, vision, health and
disability claims incurred by Employees in Buyer's employ shall be determined
under Buyer's benefit plans. Buyer agrees that Employees and their eligible
dependents will receive credit for their periods of coverage under Seller's
health or disability plans towards satisfying any preexisting condition clause
in any of Buyer's health or disability plans, provided such Employee or eligible
dependent is enrolled in Seller's plans on the Closing Date. Buyer also agrees
that Employees and their eligible dependents shall receive credit under Buyer's
health care plans for any deductibles paid by such Employee and enrolled
dependents for the current plan year under a health care plan maintained by
Seller.

         (g) Seller shall be responsible for providing any Employee whose
"qualifying event," within the meaning of Section 4980B(f) of the IRC, occurs on
or prior to the Closing Date (and such Employee's "qualified beneficiaries"
within the meaning of Section 4980B(f) of the IRC) with the continuation of
group health coverage required by Section 4980B(f) of the IRC ("Continuation
Coverage") under the terms of the health plan maintained by Seller. Buyer shall
be responsible for Continuation Coverage to any Employee in Buyer's employ (and
each Employee's qualified beneficiaries) whose qualifying event occurs after the
Closing Date to the extent required by law.

         (h) Seller agrees that it shall retain, consistent with its normal
employment practices, all liability and obligation, if any (including, without
limitation, the liability and obligation for all wages, salary, vacation pay and
unemployment, medical, dental, vision, health and disability benefits) for those
former employees of the Facilities who retired or terminated employment on or
prior to the Closing Date or who otherwise do not become employees of Buyer.

         (i) Effective as of the day after the Closing Date, Buyer shall assume
liability for severance pay and similar obligations payable to any Employee who
accepts employment with Buyer and who is terminated by Buyer on or after the
Closing Date. Such payment shall be made pursuant to Buyer's normal severance
policy and Buyer shall compute severance pay by giving Employees full credit for
all years of service that would have been recognized under Seller's severance
policy. In addition, for an Employee whose job with Buyer is eliminated by a
reduction in force or elimination of position within twelve (12) months of the
Closing Date, Buyer agrees to pay to such Employee the difference, if any,
between the amount of severance pay received by the Employee under Buyer's
severance policy and the amount such Employee would have received upon his or
her separation from the Seller under Seller's severance policy in effect at that
time.

         (j) Effective immediately after the Closing Date, the Buyer shall
assume all liability and obligation for, and Seller shall have no further
liability or obligation for, short-term disability benefits, sick pay or salary
continuation to the extent attributable to periods after the Closing Date (and
any medical, dental, vision and health benefits for claims incurred after the
Closing Date) for those Employees who accept employment with the Buyer and who
as of the day after the Closing Date are absent from work due to sickness or
short-term disability.

         (k) The Buyer shall make the offers of employment as soon as possible
after all the consents, approvals and authorizations referred to in Sections
7.1(c) and 7.2(c) hereof have been obtained (and in no event more than ten (10)
Business Days after the last of such consents, approvals and authorizations has
been obtained). Buyer will promptly notify Seller of any offer it plans to make
prior to extending such offer, and of acceptance of any such offer by any
Employee. Buyer shall be responsible for advising Employees of the details of
any offers and terms of employment, and answering any questions relating
thereto, but Seller shall be allowed to review and approve (which approval shall
not be unreasonably withheld), prior to its distribution, (i) any communication
with Employees on or prior to the Closing Date, and (ii) any communication with
such Employees after the Closing Date which describes or refers to Seller's
employee benefit plans and

policies. Buyer shall not at any time have access to Employee personnel files of
Seller.

         (l)       (i) For a period of twelve (12) months following the Closing 
         Date, neither the Seller nor any Affiliate shall solicit the employment
         (including the solicitation of any transfer of employment) of any
         Employee who is employed by Buyer; provided, however, that nothing
         herein shall prevent the Seller or its Affiliates from advertising
         generally any employment opportunities, or from hiring any Employees
         employed by Buyer who seek employment without inducement from the
         Seller.

                  (ii) For a period of twelve (12) months following the Closing
          Date, neither the Buyer nor any Affiliate shall solicit the employment
          (including the solicitation of any transfer of employment) of any
          employees of the Seller; provided, however, that nothing herein shall
          prevent the Buyer or its Affiliates from advertising generally any
          employment opportunities, or from hiring any employees of the Seller
          who seek employment without inducement from the Buyer.

                  (iii) The parties hereby acknowledge and agree that the
          failure of either party to fulfill its covenants and agreements set
          forth in this Section 2.4(l) will cause irreparable harm to such other
          party for which damages, even if available, will not be an adequate
          remedy. Accordingly, each party hereby consents to the issuance of
          injunctive relief by any court of competent jurisdiction to compel
          performance of such party's obligations under this Section 2.4(l) and
          to the granting by any such court of the remedy of specific
          performance by such party of its obligations hereunder.

         2.5 Loans

         (a) Loan Lists. As soon as practicable following the date hereof until
thirty (30) calendar days prior to the Closing Date, Seller shall provide to
Buyer within ten (10) Business Days following each month-end a cumulative list
of the Deposit-Related Loans and the Other Loans proposed to be transferred to
Buyer (or Newco in the case of the Stock Purchase) pursuant to Section 2.1
(subject to Buyer's rights as described in Section 2.5(b) to exclude certain of
such loans), prepared as of such month-end (the final Loan list prepared shall
be referred to herein as the "Final Loan List" and the date as of which such
Final Loan List is prepared shall be referred to herein as the "Loan Cut-off
Date").

         (b) Buyer's Right to Exclude Loans Prior to Closing Date.
Notwithstanding anything in this Agreement to the contrary, until fifteen (15)
calendar days prior to the Closing Date, the Buyer shall have the right to
exclude from the transaction any Loan on the Final Loan List, which excluded
loan shall not be

at any time until and including the fifteenth (15th) calendar day prior to the
Closing Date.

         (c) Deposit-Related Loans Originated After Loan Cut-off Date. Any
Deposit-Related Loan originated by Seller on or after the Loan Cut-off Date and
prior to the Closing Date in the ordinary course of Seller's business at the
Branches and the Offices shall be transferred to Buyer (or Newco in the case of
the Stock Purchase) at the Closing. As soon as practicable following the
Closing, but in any event no later than ten (10) Business Days thereafter, the
Seller shall provide to the Buyer a schedule of the Loans transferred to the
Buyer at the Closing, which schedule shall become Schedule 2.5(c) hereto upon
such delivery to Buyer.

         (d) Other Loans Originated After Loan Cut-off Date.

         (i) Any Other Loan originated by Seller on or after the Loan Cut-off
         Date and prior to the Closing Date in the ordinary course of Seller's
         business at the Branches and the Offices (collectively, the
         "Supplemental Loans") shall, subject to Buyer's rights as described in
         this Section 2.5(d) to exclude certain of such loans, be transferred to
         Buyer at a closing to be held as soon as practicable following the
         Closing Date, but in any event no later than sixty (60) calendar days
         following the Closing Date (the "Supplemental Loan Closing"). The
         Supplemental Loan Closing shall occur on the same date as the payment
         required by Section 3.2(a)(i).

         (ii) As soon as practicable following the Closing, but in any event no
         later than fifteen (15) Business Days thereafter, the Seller shall
         provide to the Buyer a schedule of the Supplemental Loans to be
         transferred to the Buyer pursuant to this Section 2.5(d), subject to
         the Buyer's rights as described herein to exclude any of the
         Supplemental Loans. Notwithstanding anything in this Agreement to the
         contrary, from and after the date on which Buyer receives such
         schedule, until ten (10) calendar days prior to the Supplemental Loan
         Closing, (A) the Seller shall provide the Buyer reasonable access
         during normal business hours to, and the opportunity to review and
         inspect, the Records relating to the Supplemental Loans; and (B) the
         Buyer shall have the right to exclude from the transaction any such
         Supplemental Loan. If the Buyer exercises its right to exclude such
         Supplemental Loan, such excluded loan shall not be transferred to the
         Buyer at the Supplemental Loan Closing. The Buyer's right to exclude
         any Supplemental Loans shall be exercisable by the Buyer giving written
         notice to the Seller at any time until and including the tenth (10th)
         calendar day prior to the Supplemental Loan Closing.

         Seller shall provide to the Buyer a schedule of the Supplemental Loans

         schedule shall become Schedule 2.5(d) hereto upon such delivery to
         Buyer. The Final Financial Statement shall be adjusted to reflect the

the Assumed Deposits and (ii) the amount of the Accrued Expenses, the Buyer

and the payment of the amounts due in respect thereof in accordance with
Sections 2.2 and 3.1 shall be final and without recourse and not subject to any
claim for reimbursement, repayment, rescission or avoidance; provided, however,
that:

         (a) The following adjustments shall be made:

                  (i) As soon as practicable after the Closing Date, but in no
         event later than sixty (60) calendar days thereafter, the Seller shall
         deliver the Final Financial Statement to the Buyer. Subject to the
         Seller's and Buyer's rights of indemnification pursuant to Section 4.4
         and Article 9, the Final Financial Statement shall become final and
         binding on the Buyer and the Seller ten (10) calendar days after its
         delivery to the Buyer, unless the Buyer gives written notice to the
         Seller of its disagreement with respect to any item included in such
         Final Financial Statement. The Seller and the Buyer shall use their
         respective reasonable efforts to resolve the disagreement during the
         ten (10) calendar day period following receipt by the Seller of the
         notice. If the disagreement is not resolved during such ten (10)
         calendar day period, the parties shall follow the procedures set forth
         in Section 9.4 to resolve such dispute and such Final Financial
         Statement shall be modified by any such resolution, whereupon the Final
         Financial Statement shall become final and binding. When the Final
         Financial Statement becomes final and binding, the Seller shall pay the
         Buyer or the Buyer shall pay the Seller, as appropriate, the difference
         between the amount paid at the Closing and the amount calculated on the
         Final Financial Statement, plus interest accrued from the Closing Date
         at the Federal Funds Rate in effect on the Closing Date. In the event
         such amounts are not paid by Seller or Buyer, as appropriate, within
         three (3) Business Days from the date the Final Financial Statement
         becomes final and binding, then such amounts shall accrue interest
         until paid at the Federal Funds Rate in effect on the Closing Date plus
         five percent (5%) per annum, but in no event in excess of the highest
         rate permitted by applicable law.

         (b) If any non-material Asset (materiality to be determined by Seller
in good faith) shall not have been assigned to the Buyer (or Newco in the case
of the Stock Purchase) at the Closing, then the Seller shall use its reasonable
efforts to assign such Asset to the Buyer as soon as possible after the Closing
Date but in any event no later than on the Settlement Date. In the event the
Seller for any reason is unable to assign any such Asset to the Buyer on or
prior to the Settlement Date, then the Seller shall no longer have any
obligation to assign such Asset to the Buyer and the Seller shall refund to the
Buyer the value of such Asset as reflected on the Closing Financial Statement
together with interest on such amount accrued from the Closing Date through the
date of such refund at the Federal Funds Rate in effect on the Closing Date;

         (c) All operating expenses and fees accrued or prepaid prior to the
Closing Date, including, without limitation, wages, salaries, rents, Bank
Insurance Fund ("BIF") premiums, utility payments, telephone charges,
maintenance contract payments, personal property taxes, non-delinquent real
property taxes and assessments relating to the Assets and the Liabilities
transferred at the Closing, but excluding fees for use of safe deposit boxes,
shall be prorated between the parties as of the Closing Date. With respect to
the BIF premiums, the proration shall be on the basis set forth in Section
3.2(d). To the extent that the Seller has paid expenses that are expenses
allocable to the Buyer pursuant to this Section 3.2(c), such expenses shall
appear as an asset on the Financial Statements. To the extent that expenses have
been accrued and not paid by the Seller prior to the Closing Date, such expenses
shall appear as a liability on the Financial Statements;

         (d) With respect to the proration of BIF premiums, Buyer shall
reimburse Seller for the amount of any BIF assessments that Seller is required
to pay for periods in which the Assumed Deposits are included in the Seller's
deposit insurance assessment base but during which periods Buyer has liability
for the Assumed Deposits. The amount of such reimbursement will be included as a
Prepaid Expense on the Financial Statements;

         (e) All loan commitment fees and any other fees accrued by or paid to
the Seller prior to the Closing Date related to the loan commitments included as
Loans pursuant to this Agreement and to any periodic fees paid or payable to
Seller with respect to the Loans shall be pro-rated between the Buyer and the
Seller. To the extent that the Seller has received fees that are fees allocable
to the period on and after the Closing Date, such fees shall appear as a
liability on the Financial Statements. To the extent that such fees allocable to
a period prior to the Closing Date have not been paid to Seller prior to the
Closing Date, such fees shall appear as an asset on the Financial Statements;

         (f) As soon as practicable after the Closing Date, the Seller will
provide to the Buyer a report of customer data for the Assumed Deposits showing
the names, addresses, tax identification numbers (where available from the
Seller's records) and deposit balances of each and all of the customers with
Assumed Deposits as of such date; the customer data shall include the signature
cards in the possession of Seller for all Assumed Deposits and a list of
Accounts subject as of the Closing Date to annual Taxpayer Identification Number
solicitation by Seller in the normal course of its business;

         (g) With respect to IRA Deposits, the Seller will use reasonable
efforts and will cooperate with the Buyer, both 


                                      -26-

   31


before and after the Closing, in taking whatever actions are reasonably
necessary to accomplish either the appointment of the Buyer as successor
custodian, the adoption of Buyer's form of IRA plan (or such plan of an
Affiliate of Buyer), or the delegation to the Buyer (or an Affiliate of the
Buyer) of the Seller's authority and responsibility as custodian of all such IRA
Deposits, including but not limited to, sending to the depositors thereof
appropriate notices, and filing any appropriate applications with applicable
regulatory authorities. If any such delegation is made to the Buyer (or such
Affiliate), the Buyer (or such Affiliate) will perform all of the duties so
delegated and comply with the terms of the Seller's agreement with the depositor
of the IRA Deposits affected thereby;

         (h) With respect to Deposits which are Keogh Accounts, the Seller will
use reasonable efforts and cooperate with the Buyer to invite trustees of Keogh
plans to appoint the Buyer (or an Affiliate of the Buyer) as successor custodian
of each Keogh Account and related Deposit thereof, and to adopt the Buyer's (or
such Affiliate's) form of Keogh Master Plan as a successor to that of the
Seller. The Buyer (or such Affiliate) will assume no Deposits which are Keogh
Accounts unless the Buyer (or such Affiliate) has received the documents
necessary for such assumption or transfer at or before the Closing. With respect
to any depositors who do not transfer such accounts to the Buyer's (or such
Affiliate's) form of Keogh Master Plan, the Seller will use reasonable efforts
in order to enable the Buyer (or such Affiliate) to retain such Keogh Accounts
at the Branches at which such accounts were maintained;

         (i) Any items that were credited for deposit to or cashed against an
         Assumed Deposit prior to the Closing and are returned unpaid (each, an
         "RI") within 60 days after the Closing Date will be handled as follows:

                  (A) Within one (1) Business Day after receipt of any RI by the
                  Seller, the Seller will fax to the Buyer a list reflecting the
                  amount of such RI, the date of deposit and depositor's account
                  number (if available) and the Seller will forward a
                  consolidated collection request with the original RIs (a
                  "Collection Advice"), to the Buyer via Seller's courier, at
                  Buyer's expense.

                  (B) Upon receipt of a Collection Advice, the Buyer will place
                  holds on the respective customers' deposit accounts with the
                  Buyer ("Customer Account") in an amount not less than the
                  amount of the RI and take any actions necessary to ensure that
                  such deposits are not withdrawn.

                  (C) Within one (1) Business Day after receipt of such
                  Collection Advice and original RI, the Buyer will debit the
                  available Customer Account and/or overdraw 


                                      -27-

   32


                  the Customer Account and return the paid collection request to
                  the Seller. If there are not sufficient funds in the Customer
                  Account because of the Buyer's failure to honor holds placed
                  on such Customer Account, the Buyer shall repay the amount of
                  the RI to the Seller. RIs that overdraw an account balance
                  shall be held by the Buyer unless requested by the Seller
                  during the collection process. The Buyer will release RIs to
                  depositors only upon receipt of sufficient good funds to cover
                  any deficient balances.

                  (D) A list reflecting name, address, phone number and amount
                  of accounts overdrawn $500 or more, resulting from an RI
                  forwarded by the Seller being charged to the Customer Account,
                  shall be faxed to the Seller, Attention: Loss Prevention
                  Manager, fax number 602-431-7156, on the date such item is
                  charged back.

                  (E) The Seller will be responsible for collecting overdrawn
                  balances of RIs over $500. The Buyer will cooperate with the
                  Seller with respect to providing information or records that
                  may be needed to pursue resolution of amounts due to the
                  Seller. The Buyer will be responsible for reasonable
                  collection efforts on overdrawn balances of RIs of $500 or
                  less.

                  (F) After a period of 60 days from the date a Customer Account
                  is charged for an RI and becomes overdrawn, the Buyer will
                  submit a collection request to the Seller for any remaining
                  balances that could not be collected. The original RIs
                  received shall be returned to the Seller with the collection
                  letter.

                  (G) Customer disputes regarding Buyer's rights to debit
                  Customer Accounts will be reviewed with Seller's Loss
                  Prevention Manager for resolution. The Buyer agrees to
                  cooperate with the Seller in debiting Customer Accounts for
                  RIs, except in such cases when Seller's negligence is the
                  basis of a defense by the customer to Buyer's right to debit
                  the Assumed Deposit(s).

                  (H) Claims involving checks paid prior to Closing, drawn
                  against Accounts sold, which are subsequently disputed to be
                  forged or otherwise unauthorized, shall be referred to
                  Seller's Loss Prevention Manager for resolution.

         (ii) Any RIs that are returned unpaid more than sixty (60) calendar
         days after the Closing Date will be the responsibility of the Buyer,
         except that Seller shall be responsible, for a period of eighteen (18)
         months after the Closing Date, for RIs when such items are one of the
         following: checks drawn on the United States Treasury, 


                                      -28-

   33


         checks issued by state governments or municipalities or checks returned
         for endorsement irregularities; provided that the Buyer shall cooperate
         with Seller as provided in subsection 3.2(i)(i) above to obtain
         collection of such items from the applicable Customer Account.

         (j) As soon as practicable, but in any event no later than five (5)
calendar days after the Closing Date, the Buyer shall mail to each depositor in
respect of a Transaction Account (included in the Assumed Deposits) a letter
approved in writing by the Seller requesting that such depositor promptly cease
writing checks or drafts on the Seller's check stock against such Transaction
Account. At such time as the Buyer mails each such notice to each such
depositor, the Buyer shall also forward to each such depositor new checks on the
Buyer's stock, which checks the depositor may draw upon the Buyer for the
purpose of effecting transactions with respect to such Transaction Accounts.

         The parties hereto shall use reasonable efforts to develop procedures
that cause checks drawn on the Seller's form of check stock against Transaction
Accounts that are received after the Closing Date to be cleared through the
Buyer's then current clearing procedures.

         During the ninety (90) calendar day period following the Closing Date,
if it is not possible to clear Transaction Account drafts through the Buyer's
then current clearing procedures after the Closing Date, the Seller shall
forward to the Buyer no later than the next Business Day after receipt thereof
all such Transaction Account drafts drawn against Assumed Deposit Accounts. The
Seller shall have no obligation to pay such Transaction Account drafts. Upon the
expiration of such ninety (90) calendar day period, the Seller shall cease
forwarding drafts against Transaction Accounts transferred on the Closing Date
and shall instead return them to the originators marked "Refer to Maker-Branch
Sold." The Buyer will compensate the Seller for processing of drafts as
described in this Section 3.2(j) according to the compensation arrangement set
forth in Section 4.6;

         (k) Collection of Overdrafts, if any such collection is effected by the
Buyer in its sole discretion, shall be the sole responsibility of the Buyer. At
the Buyer's request, the Seller will use reasonable efforts to cooperate to
assist in collection of Overdrafts, but the Seller shall not be required to
incur any fees or expenses (including legal or other professional fees) other
than the indirect costs associated with the employment of Seller's existing
employees in connection with rendering such assistance.

         (l) In connection with the transfer of the Loans, Seller and Buyer
agree as follows:



                                      -29-
- --------------------------------------------------------------------------------
BRANCH PURCHASE AGREEMENT

   34


                  (i) The parties will cooperate and use their reasonable
         efforts to cause Buyer to become the beneficiary of credit life,
         accident and health, vendor's single interest premium or similar
         insurance purchased by or on behalf of customers on the Loans. For the
         duration of such insurance, Seller and Buyer agree to cooperate in good
         faith to develop a mutually satisfactory method by which the issuer of
         such insurance will make rebate payments to and satisfy claims of the
         holders of such certificates of insurance after the Closing Date.

                  (ii) Each of Buyer and Seller will use their reasonable
         efforts to comply with all notice and reporting requirements of the
         Loan documents or of any law or regulation with respect to the transfer
         of such Loans.

                  (iii) Within thirty (30) calendar days after the Closing Date
         or the Supplemental Loan Closing (as appropriate), Buyer will, at its
         expense, issue new coupon books or similar payment notices for payment
         of Loans with instructions to use Buyer's coupons or statements and to
         destroy unused coupons furnished by Seller.

                  (iv) For a period of sixty (60) calendar days after the
         Closing Date or the Supplemental Loan Closing (as appropriate), within
         five (5) Business Days after receipt by Seller of any check or money
         order made payable to Seller representing payment on a Loan, such item
         shall be settled in accordance with mutual settlement procedures to be
         agreed between Seller and Buyer as soon as practicable following the
         date hereof. If the item is returned unpaid, however, Seller shall
         promptly notify Buyer of such item's return and shall forward the
         original of such item to Buyer. Within three (3) Business Days after
         receipt of such returned item, Buyer shall issue and forward a
         cashier's check or wire transfer to Seller in the amount of such item,
         and Buyer shall be responsible for any further efforts to collect such
         item.

                  (v) If the balance due on any Loan has been reduced by Seller
         as a result of a payment by check received prior to the Closing Date or
         the Supplemental Loan Closing (as appropriate), which item is returned
         after the Closing Date or the Supplemental Loan Closing (as
         appropriate), the asset value representing the Loan transferred shall
         be correspondingly increased and an amount in cash equal to such
         increase shall be paid by Buyer to Seller promptly upon demand. Such
         amounts shall be debited or credited, where applicable, from Buyer's
         correspondent bank account maintained with Seller.

         (a) To use reasonable efforts to sign and deliver to the Buyer such
additional agreements and other documents, and to do such other acts and things,
as may be required to complete the transactions contemplated by this Agreement.

         (b) To reasonably cooperate with the Buyer in obtaining all
governmental and regulatory consents, approvals, licenses, waivers and the like
required to be fulfilled or obtained for the completion of the transactions
contemplated by this Agreement.

         (c) To deliver to the Buyer those Records relating solely to the Assets
and the Liabilities and being easily segregable from the Seller's other records,
as soon as practicable after the Closing and to store the other books, records
and accounts of the Facilities relating to the Seller's former operation of the
Facilities for the applicable period required by law.

         (d) Until Closing or the earlier termination of this Agreement, to
cause the business of the Facilities to be conducted in accordance with Section
2.3 above.

         (e) To remove all signage from the Facilities at the expense of the
Seller on or before the Closing Date, it being understood that the Buyer shall
be responsible for installation of its signage at its sole expense on or after
the Closing Date.

         (f) As soon as practicable after the receipt of all regulatory
approvals required by Sections 7.1(c) and 7.2(c) with respect to all Facilities,
and no later than thirty (30) calendar days prior to the Closing Date (unless
earlier required by law, regulation or regulatory policy), each of the Seller
and the Buyer shall provide, or join in providing where appropriate, all
notices, separately as to each Branch, to holders of Deposits, borrowers under
the Loans and other persons that the Seller or the Buyer, as the case may be, is
required to give by any regulatory authority having jurisdiction or under
applicable law or the terms of any other agreement between the Seller and any
customer in connection with the transactions contemplated hereby. A party
proposing to send or publish any notice or communication pursuant to this
Section 4.1(f) shall furnish to the other party a copy of the proposed form of
such notice or communication as soon as practicable in advance of the proposed
date of the first mailing, posting, or other dissemination thereof to customers,
and shall not unreasonably refuse to amend such notice to incorporate any
changes that the other such party proposes as necessary to comply with
applicable statutes, rules, regulations or requirements of any regulatory
authority having jurisdiction. All costs and expenses of any notice or
communication sent or published by the Buyer or the Seller 

                                      -31-

   36


shall be the responsibility of the party sending such notice or communication.
All out-of-pocket costs and expenses of any joint notice or communication which
Buyer or Seller pays to a third party vendor shall be shared equally by the
Seller and the Buyer. Each party shall bear the costs and expenses of its own
employees or agents engaged in any joint notice or communication.

         (g) The Seller will use reasonable efforts to transfer to the Buyer on
or as soon as practicable after the Closing Date all of those automated clearing
house and fed wire direct deposit arrangements which are tied by agreement or
other standing arrangement to Assumed Deposits. For a period of ninety (90)
calendar days after the Closing Date, in the case of automated clearing house
direct deposits to Assumed Deposits, and thirty (30) calendar days after the
Closing Date, in the case of fed wire direct deposits to Assumed Deposits (each,
a "Direct Deposit Cut-off Date"), the Seller will, no later than the next
Business Day following the date of receipt thereof, remit and transfer to the
Buyer all direct deposits intended for Accounts which are Assumed Deposits.
After the applicable Direct Deposit Cut-off Date, the Seller may discontinue
accepting and forwarding automated clearing house and fed wire entries and funds
and return such direct deposits to the originators. The Seller shall not be
liable for any account overdrafts that may thereby be created or for any other
matter. The Seller will not be obligated to accept new direct deposit
arrangements on any Account after the date that all regulatory approvals
required under Sections 7.1(c) and 7.2(c) (except for statutory waiting periods)
have been received, nor will the Seller be obligated to remit or transfer with
respect to any direct deposit arrangements other than by electronic
transmission. At the time of each Direct Deposit Cut-off Date, the Buyer will
provide automated clearing house originators with account numbers and conversion
tapes relating to Assumed Deposits.

         (h) As soon as practicable after the receipt of all regulatory
approvals required by Sections 7.1(c) and 7.2(c) with respect to all Facilities
(except for statutory waiting periods), and after the notice provided in Section
4.1(f), the Buyer will send appropriate notice to all holders of Deposits which
are to be assumed by the Buyer at the Closing the terms of which provide for
direct debit of such accounts by third parties ("Direct Debit Accounts"),
instructing such customers concerning transfer of customer direct debit
authorizations from the Seller to Buyer. The Seller shall cooperate in
soliciting the transfer of such authorizations. Such notice shall be in a form
agreed to by the parties. For a period of ninety (90) calendar days following
the Closing Date, the Seller will, on the Business Day following the date of
receipt thereof, forward to the Buyer all direct debits on Direct Debit Accounts
and will give the Buyer a daily accounting by electronic transmission of such
debits to the Buyer's clearing account. Thereafter, the Seller may discontinue
forwarding 


                                      -32-

such entries and return them to the originators marked "Refer to Maker--Branch
Sold." The Seller will not be obligated to accept new direct debit arrangements
on any Account after the date that all regulatory approvals required under
Sections 7.1(c) and 7.2(c) (except for statutory waiting periods) have been
received, nor will the Seller be obligated to forward such direct debits or give
an accounting thereof other than by electronic transmission. At the time of the
Closing Date, the Buyer will provide automated clearing house originators of

originators to change the routing transit number for such deposits and debits
from the Seller's routing transit number to the Buyer's routing transit number.

         (j) From and after the Closing, the Seller will not:

         (i)      use any of the information contained in the Records for any
                  purpose other than for the purpose of enforcing rights and
                  performing obligations arising under this Agreement; and

         (ii)     for a period of eighteen (18) months following the Closing
                  Date, conduct or, following the closing of the

                  solicitation of depositors of the Assumed Deposits, except in
                  connection with general solicitations or general advertising
                  not targeted specifically at the depositors of the Assumed
                  Deposits.

         (i) To obtain approval of this Agreement and the transactions

relations with its depositors, customers and others, and not, either before or
after the Closing, to commit any act, or in any way assist others to commit any
act, that injures Seller or the business heretofore conducted by Seller, and,
without limiting the generality of the foregoing, not to divulge any
confidential information or make available to any others any documents, files or
other papers concerning the business or financial affairs of Seller.

         4.3 Consents. The Seller shall use its reasonable efforts to obtain any
nongovernmental consents required for the transfer or assignment of the Assets
and Liabilities to Buyer (or Newco in the case of the Stock Purchase) pursuant
to this Agreement, including (a) Leases, if any, and (b) Assumed Contracts, if

additional compensation or fee to any person or entity to obtain any such
consent, (ii) the Buyer agrees that it shall provide reasonable assistance to
the Seller to obtain such consents, and (iii) the Seller shall be entitled to
rely on the provisions of Sections 2.2(e) and 2.2(f) and the final paragraph of
Section 7.2 if Seller does not obtain one or more such consents.

         4.4 Environmental Matters.

         (a) The provisions of this Section 4.4 shall exclusively govern the

Substances.

         (b) Seller has delivered to the Buyer copies of a Phase I Environmental
Site Assessment ("Phase I") and an Asbestos Survey ("Asbestos Survey") regarding
each tract of Real Estate; provided that Seller has not delivered an Asbestos
Survey regarding any Branch or Office where construction of all Improvements was

4.4(b). The cost of such Phase I's and Asbestos Surveys shall be borne by the
Seller.

         The Buyer acknowledges and agrees that:

                  (i) Seller is furnishing copies of the Phase I's and Asbestos
          Surveys to Buyer for informational purposes only and without
          representation or warranty as to the accuracy or completeness of the
          contents of such materials except as otherwise provided in this
          Section 4.4;

                  (ii) Buyer will not rely on the Phase I's or Asbestos Surveys
          and will conduct its own due diligence on the matters contained in the
          documents; and

                  (iii) Buyer is not purchasing the Real Estate, Improvements
          and Leasehold Improvements and accepting assignment of the Leases in
          reliance upon any representations or warranties of any kind whatsoever
          made by the Seller (or any representatives, agents or employees of the
          Seller) except those made or contained in this Agreement.

         Buyer and Seller acknowledge and agree that, prior to Closing, Buyer
will have the opportunity to independently and personally inspect the Real
Estate, Improvements, Leased Real Estate and Leasehold Improvements (sometimes
referred to collectively in this Section 4.4 as the "Subject Assets"). Buyer
further acknowledges and agrees that Buyer has entered into this Agreement based
upon this right of inspection. It is expressly agreed and understood that Seller
has made no representation or warranty as to the condition of any of the Subject
Assets or their suitability for any particular purpose except as expressly set
forth in this Agreement. Buyer agrees that the Real Estate, Improvements and
Leasehold Improvements are to be sold to and purchased by Buyer, and the Leases
assigned to and accepted by Buyer, "AS IS" AND "WHERE IS," WITH ALL FAULTS, IF
ANY, INCLUDING, WITHOUT LIMITATION, THE ENVIRONMENTAL CONDITION OF THE PROPERTY,
AND WITHOUT ANY WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, except as expressly set
forth in this Agreement.

         (c) During the thirty (30) Business Day period starting on the date of
this Agreement ("Environmental Due Diligence Period"), Buyer shall have the
right to conduct environmental assessments, investigations, reviews or testing
performed by Buyer or any third party or consultant engaged by Buyer to conduct
such study (collectively, "Environmental Assessments") of the Subject Assets,
and Buyer and Buyer's representatives, agents and designees will have the right,
at reasonable times and upon reasonable notice to Seller (which notice must
describe the scope of the planned testing and investigations) to enter upon the
Real Estate and Leased Real Estate subject to the terms and conditions set forth
in Exhibit H.

   41


         (d) During the Environmental Due Diligence Period, Buyer may notify
Seller in writing of any objections relating to any aspects of the Subject
Assets relating to one or more Facilities (the "Affected Facilities") pertaining
to presence of any Hazardous Substances, compliance with all applicable
Environmental Laws, any matters disclosed in the Phase I's or Asbestos Surveys,
any matters disclosed by Seller, or any matters disclosed in any Environmental
Assessments.

                  (i) In the event that Buyer fails to so notify Seller of any
          such objections, Buyer shall be deemed to have approved such items.

                  (ii) In the event, however, that Buyer notifies Seller in
          writing and within the Environmental Due Diligence Period of any such
          objections, the parties will have a period of ten (10) Business Days
          to agree upon a resolution of the objection(s). If the parties cannot
          agree within such period of ten (10) Business Days, then within five
          (5) Business Days after the expiration of such period either party may
          initiate a proceeding to resolve such objections pursuant to the
          procedures set forth in Section 9.4 of this Agreement; provided,
          however, that within such five (5) Business Days the Seller in its
          sole discretion may, in a case where Buyer has notified Seller of
          objections with respect to Real Estate or Improvements, elect to
          remove the Real Estate and Improvements relating to the Affected
          Facilities from the Assets to be sold and transferred to Buyer, in
          which event (A) the consideration payable under Article 3 shall
          automatically be adjusted accordingly and (B) commencing on the
          Closing Date Buyer shall lease the Real Estate and Improvements
          relating to the Affected Facilities from Seller for a period of at
          least six (6) months, at a rental rate and on terms to be agreed upon
          by Buyer and Seller, which rate and terms shall be commercially
          reasonable and comparable to those for similar properties in the
          vicinities of the Affected Facilities, and provided further, that if
          Buyer and Seller do not agree upon the rental rate or one or more such
          terms within an additional ten (10) Business Days after expiration of
          the five (5) Business Day period referred to above, then the
          determination of such rate and/or term(s) shall be immediately
          submitted to arbitration pursuant to the procedures set forth in
          Section 9.4 of this Agreement. In a case where Buyer has notified
          Seller of objections with respect to Leased Real Estate or Leasehold
          Improvements, then if neither party has initiated a proceeding to
          resolve such objections pursuant to the procedures set forth in
          Section 9.4 of this Agreement within the five (5) Business Days
          referred to in the immediately preceding sentence, then the Seller in
          its sole 


                                      -37-

         discretion may elect to exercise its right under the final paragraph of
         Section 7.2 to exclude the Affected Facility (but not the other Assets
         and Liabilities related thereto) from the Closing.

                  (iii) If this Agreement is not amended or otherwise modified
          pursuant to the provisions of the foregoing Section 4.4(d)(ii), Buyer
          shall be deemed to have waived its objections and this Agreement will
          continue in full force and effect.

         (e)      (i) Subject to Subsection 4.4(e)(iii) and Article 9 below, 
         if there are any third party claims against Buyer that arise out of any
         Hazardous Substances that became located in, on or under Real Estate
         during Seller's ownership of the Real Estate, or in, on or under Leased
         Real Estate during the term of Seller's Lease, Seller will (to the
         extent the Seller is liable for such Hazardous Substances under any
         federal, state or local law pertaining to or concerning Hazardous
         Substances) indemnify, defend (by counsel reasonably acceptable to
         Buyer), protect and hold Buyer harmless for, from and against any and
         all claims, liabilities, penalties, forfeitures, losses or expenses
         (including, without limitation, reasonable expenses of investigation
         and attorney's fees and expenses in connection with any action, suit or
         proceeding brought against the Buyer) arising therefrom (to the extent
         that any such third party claims are attributable to the portion of the
         Hazardous Substances which occurred or were in existence at the Real
         Estate or Leased Real Estate on or prior to the Closing Date) in an
         amount which (together with any amount for which Seller may become
         liable to provide indemnification pursuant to Section 9.2 or
         otherwise), shall not exceed the amount of $5,000,000, and provided
         that notwithstanding any other provision hereof, Seller shall not be
         liable under this Section 4.4(e)(i) for any losses sustained by the
         Buyer unless and until the aggregate amount of all losses with respect
         to a Facility sustained by the Buyer to be indemnified by the Seller
         under this Agreement (including any amount for which Seller may become
         liable to provide indemnification pursuant to Section 9.2 or
         otherwise), shall exceed $100,000, in which event the Seller shall be
         liable only for such losses in excess of $100,000 with respect to that
         Facility (it being the intention of the parties that losses sustained
         by the Buyer with respect to one Facility shall not be combined with
         losses sustained with respect to another Facility to satisfy such
         minimum $100,000 amount).

                  (ii) Subject to Subsection 4.4(e)(iii) and Article 9 below, if
         there are any third party claims against Seller that arise out of any
         Hazardous Substances that became located in, on or under the Real
         Estate or Leased Real Estate at any time after the Closing, Buyer will


                                      -38-

BRANCH PURCHASE AGREEMENT

   43


         indemnify, defend (by counsel reasonably acceptable to Seller), protect
         and hold Seller harmless for, from and against any and all claims,
         liabilities, penalties, forfeitures, losses or expenses (including,
         without limitation, reasonable expenses of investigation and attorney's
         fees and expenses in connection with any action, suit or proceeding
         brought against the Seller) arising therefrom, provided that
         notwithstanding any other provision hereof, Buyer shall not be liable
         under this Section 4.4(e)(ii) for any losses sustained by the Seller
         unless and until the aggregate amount of all losses with respect to a
         Facility sustained by the Seller to be indemnified by the Buyer under
         this Agreement (including any amount for which Buyer may become liable
         to provide indemnification pursuant to Section 9.3 or otherwise), shall
         exceed $100,000, in which event the Buyer shall be liable only for such
         losses in excess of $100,000 with respect to that Facility (it being
         the intention of the parties that losses sustained by the Seller with
         respect to one Facility shall not be combined with losses sustained
         with respect to another Facility to satisfy such minimum $100,000
         amount).

                  (iii) Nothing in this Section 4.4(e) is meant to diminish any
         party's rights or obligations under any federal, state or local law
         pertaining to or concerning Hazardous Substances; but Seller will not
         be liable to Buyer under this Agreement, and Buyer hereby releases
         Seller from any and all liability under any such law, for any third
         party claims which are attributable to any environmental condition
         which:

                           (A) was described or referred to in the Phase I's,
                  Asbestos Surveys or any Environmental Assessments obtained or
                  conducted by Buyer;

                           (B) was reasonably discoverable by prudent
                  investigation during the Environmental Due Diligence Period;
                  or

                           (C) was otherwise disclosed by Seller to Buyer or
                  discovered by Buyer at any time prior to the Closing.

                  (iv) The above release includes claims of which Buyer is
         presently unaware or which Buyer does not presently suspect to exist
         which, if known by Buyer, would materially affect Buyer's release(s) to
         Seller. It is understood and agreed that the purchase price has been
         adjusted by prior negotiations to reflect that all of the Real Estate,
         Improvements, Leasehold Improvements and the Furniture, Fixtures and
         Equipment are sold by Seller and purchased by Buyer and Buyer is
         accepting assignment of the Leases subject to the foregoing. The sole
         remedy of the Buyer will be to exercise its rights under Section 4.4(b)
         prior to the end of the Environmental Due Diligence Period.

         4.5 Valuation of the Assets. Buyer agrees that it is relying solely
upon its own judgment as to the value of the Assets and the Liabilities (and the
Shares in the case of the Stock Purchase), and Seller hereby disclaims any
representations or warranties made by Seller as to their condition, value,
nature or amount except those made in Section 5.1 of this Agreement, and subject
to the provisions of Section 4.4 of this Agreement, which shall exclusively
govern the rights and obligations of the parties with regard to Hazardous
Substances.

         4.6 Clearing Items. From the Closing Date and for ninety (90) calendar
days thereafter, items drawn on Transaction Accounts assumed by the Buyer may
continue to be presented to the Seller. The Seller will make provisional
settlement to the presenting institution and will forward such items to the
Buyer, via courier, at Buyer's expense, no later then the next Business Day
after receipt thereof, and the Buyer will reimburse the Seller for such
provisional settlement. For the first ninety (90) calendar days following the
Closing Date, the Seller shall perform its obligations under the first two
sentences of this Section 4.6 at no cost to the Buyer. After ninety (90)
calendar days from the Closing Date, the Buyer will pay the Seller $10.00 for
each item processed by the Seller. Upon timely presentation to the Buyer, the
Buyer will assume all responsibility for such items (except for such items which
have not been handled by the Seller in accordance with applicable law or
regulation, or with ordinary care), including but not limited to determining
whether to honor or dishonor such items and giving any required notification for
the return of large items.

         4.7 IRA Deposits and Keogh Accounts. The Seller will deliver to the
Buyer, on the Closing Date, copies of the Seller's documents for each IRA
Deposit and Keogh Account which is included in the Assumed Deposits. The Seller
will prepare and file all reports to government authorities required to be filed
for the period ending on the Closing Date and all prior periods. The Buyer will
be responsible for all such reporting for periods commencing on the day after
the Closing.

         4.8 Interest Reporting and Withholding.

         (a) Except as set forth in Section 4.8(b), for the period from January
1 of the year in which the Closing occurs through the Closing Date, Seller will
provide to Buyer all information necessary for Buyer to report to applicable
taxing authorities and owners of Assumed Deposits transferred on the Closing
Date, all interest credited to, withheld from and any early withdrawal penalties
imposed upon the Assumed Deposits during 


                                      -40-

such period (collectively, the "Reported Amounts"). With respect to all periods
beginning on or after January 1 of the year in which the Closing occurs, Buyer
will report all Reported Amounts to applicable taxing authorities and owners of
Assumed Deposits transferred on the Closing Date.

         (b) With respect to any Assumed Deposits for which amounts are required
by any governmental agency to be withheld (the "Withholding Accounts"):

                  (i) Seller will: (A) for the period from January 1 of the year
         in which the Closing occurs through the Closing Date, report all
         Reported Amounts incurred during such period on the Withholding
         Accounts to applicable taxing authorities and to the owners of the
         Withholding Accounts; and (B) withhold any amounts required by any
         governmental agencies to be withheld from the Withholding Accounts on
         or before the Closing Date in accordance with applicable law or
         appropriate notice from any governmental agency and remit such amounts
         to the appropriate agency on or prior to the applicable due date.

                  (ii) Buyer will: (A) for the period from the day after the
         Closing Date to the end of the calendar year (and all periods
         thereafter), report all Reported Amounts incurred during such period on
         the Withholding Accounts to applicable taxing authorities and to the
         owners of the Withholding Accounts; and (B) withhold any amounts
         required by any governmental agencies to be withheld from the
         Withholding Accounts after the Closing Date in accordance with
         applicable law or appropriate notice from any governmental agency and
         remit such amounts to the appropriate agency on or prior to the
         applicable due date.

         (c) Buyer shall report to applicable taxing authorities and the
borrowers of the Loans all interest paid on such loans for the year in which
such loans are acquired by Buyer.

         4.9 Eminent Domain or Taking. If proceedings under a power of eminent
domain relating to a specific Facility or any part thereof (the "Taking
Facility") are commenced prior to the Closing Date, Seller will promptly inform
Buyer in writing.

         (a) If such proceedings involve the taking of all of or a material
interest in the Taking Facility, Buyer may elect to terminate this Agreement
with respect to such Taking Facility (but not the other Assets and Liabilities
related thereto) by notice in writing sent within ten (10) calendar days of
Seller's written notice to Buyer, in which case neither party will have any
further obligation to or rights against the other with respect to the Taking
Facility except with respect to the Deposits of such Facility and except any
rights or obligations 


                                      -41-

of either party which are expressly stated to survive termination of this
Agreement.

         (b) If the proceedings do not involve the taking of all of or a
material interest in the Taking Facility , or if Buyer does not elect to
terminate this Agreement as to the Taking Facility, this transaction will be
consummated as described herein, and, subject to the Lease, if any, or other
encumbrances, if any, relating to the Taking Facility, any award or settlement
payable with respect to such proceeding will be paid or assigned to Buyer on the
Closing Date.

         (c) If the Closing contemplated by this Agreement is not consummated
for any reason, Buyer will have no claim to any condemnation award or settlement
with respect to the Taking Facility.

         4.10 Damage or Destruction. Except as provided in this Section 4.10,
prior to the Closing Date, as between Seller and Buyer the entire risk of loss
or damage by earthquake, flood, landslide, fire or other casualty is borne and
assumed by Seller. If, prior to the Closing Date, any part of the Improvements
or Leasehold Improvements at a specific Facility (the "Affected Improvements")
is damaged or destroyed by earthquake, flood, landslide, fire or other casualty,
Seller will promptly inform Buyer of such fact in writing and advise Buyer as to
the extent of the damage and whether it is, in Seller's reasonable opinion,
"MATERIAL."

         (a) If Seller determines that such damage or destruction is "MATERIAL",
Buyer has the option to terminate its obligation to acquire such Facility (but
not the other Assets and Liabilities related thereto) (the "Damaged Facility")
upon written notice to the Seller given not later than ten (10) calendar days
after receipt of Seller's written notice to Buyer advising of such damage or
destruction.

         (b) For purposes of this Section 4.10, "MATERIAL" shall mean any damage
or destruction to the Affected Improvements where the cost of repair or
replacement is estimated to be (i) in the case of damage or destruction to
Improvements, more than twenty-five (25) percent of the Market Value of the Real
Estate and Improvements, or (ii) in the case of damage or destruction to
Leasehold Improvements, more than twenty-five (25) percent of the amount
indicated in Section 3.1 and Schedule 3.1(b) for the Leasehold Improvements at
the Damaged Facility ("Leasehold Improvements Value"), and that in either case
will take more than sixty (60) calendar days to repair.

         (c) If the obligation to acquire the Damaged Facility is so terminated,
neither party will have any further obligation to or rights against the other
with respect to such Damaged Facility except with respect to the other Assets
and Liabilities of such Facility and except any rights or obligations of either
party which are expressly stated to survive termination of this Agreement.

         (d) Subject to the Lease, if any, or other encumbrances, if any, if the
Buyer does not elect to terminate its obligation to acquire the Damaged
Facility, or if the casualty is not material, Seller shall either (i) reduce the
Market Value of the Real Estate or the Leasehold Improvements Value at the
Damaged Facility, as the case may be, by the value reasonably estimated by
Seller to repair or restore the damaged portion of the Affected Improvements,
less any sums expended by Seller to make emergency repairs to the Affected
Improvements, or (ii) repair or restore the damaged portion of the Affected
Improvements, and in either case this transaction will close pursuant to the
terms of this Agreement, and the Buyer will accept the Damaged Facility as is,
where is, without recourse, with all faults and with no warranties other than as
expressly provided in Section 5.1 of this Agreement, and subject to the
provisions of Section 4.4 of this Agreement, which shall exclusively govern the
rights and obligations of the parties with regard to Hazardous Substances.

         (e) If the damage is not material, Seller's notice to Buyer of the
damage or destruction will also set forth the reduced Market Value of the Real
Estate or the reduced Leasehold Improvements Value at the Damaged Facility, as
the case may be, and Seller's allocation of value to the damaged portion of the
Affected Improvements. If Buyer does not accept Seller's reduced valuation,
Buyer's sole remedy will be to submit the issue to arbitration pursuant to
Section 9.4 hereof.

         (f) Whether or not the sale of the Damaged Facility is consummated
hereunder, Buyer shall have no rights to insurance claims or proceeds in respect
of damage or destruction to the Affected Improvements occurring prior to the
Closing Date.

New Mexico State Board of Registration for Professional Engineers and Surveyors
(the "Survey") of the Real Estate prepared and certified as to all matters shown
thereon by a surveyor licensed by the State of New Mexico ("Surveyor").

         (b) Prior to the date hereof, Seller has caused the Title Company to
furnish to Buyer (i) a title commitment ("Commitment"), showing Seller as the

standard coverage ("Title Policy") in the amount of the Market Value of the Real
Estate and Improvements on the standard form therefor promulgated by the New
Mexico Department of Insurance insuring Buyer's fee simple title to the Real

Schedule B exceptions; and (ii) a photocopy of all documents ("Title Documents")
describing all Schedule B title exceptions shown on the Commitment. Unless Buyer
has objected thereto prior to the date hereof, all matters shown on the Survey
and exceptions listed in the Commitment are conclusively deemed to be acceptable
to Buyer. Seller shall provide to Buyer the Title Policy, reflecting only the
Permitted Exceptions, as soon as practicable after the Closing Date. As used in
this Agreement, the term "Permitted Exceptions" shall mean all title exceptions
or Survey matters which would not materially impair the ability of the Buyer to
utilize the Real Estate as a banking facility, and all matters either shown on
the Survey or listed in the Commitment to which Buyer has not objected prior to
the date hereof, or, having objected, Buyer has thereafter waived. Seller and
Buyer shall share equally in the cost and expense of the Title Policy.

         (c) Prior to the date hereof, Seller submitted appraisals of the Market
Value of the Real Estate and Improvements to Buyer.

         (d) Upon consummation of the transactions contemplated by this

shall acquire such cash management relationships, subject to Buyer's rights as
described in Section 4.12(b) to exclude certain of such relationships from the

         (b) Notwithstanding anything in this Agreement to the contrary, from
the date hereof until thirty (30) calendar days after the Closing Date, the
Buyer shall have the right to exclude from the transaction one or more of such
cash management relationships. The Buyer's right to exclude such cash management
relationship(s) shall be exercisable by the Buyer giving written notice to the
Seller at any time until and including the thirtieth (30th) calendar day after
the Closing Date. If, prior to the Closing, the Buyer does not exercise its
right to exclude any of the cash management relationship(s) described on
Schedule 4.12, such cash management relationships (including cash management
accounts and related lines of credit and loans) shall be transferred to the
Buyer at the Closing. If the Buyer exercises its right to exclude any of the
cash management relationship(s) described on Schedule 4.12, the entire cash
management relationship (including cash management accounts and related lines of
credit and loans) shall be retained by the Seller (if Buyer exercises its right
to exclude

Seller (if Buyer exercises its right to exclude such cash management
relationship(s) during the thirty-day period following Closing). The Closing

         (c) Notwithstanding anything in this Agreement to the contrary, for a

general solicitations or general advertising not targeted specifically at such
customers, or (ii) any solicitation of any such customer who, prior to the
closing of the BankAmerica/NationsBank Business Combination, had a pre-existing
customer relationship with NationsBank, N.A.

         4.13 Additional Branches.

         (a) As soon as practicable, but in no event later than 20 calendar days
following the date hereof, the Seller shall provide to the Buyer deposit, loan,
employee, facilities and related information (the "Additional Information")
regarding each of the Branches listed on Schedule A-1 designated as "Additional
Branches" (the "Additional Branches") in format and scope similar to information
delivered to the Buyer prior to the date hereof regarding the Branches other
than the Additional Branches.

         (b) The Additional Information shall be deemed to be satisfactory and
accepted by the Buyer unless, within 20 calendar days of the receipt by the

that, based on its review of the Additional Information, the Buyer in good faith
believes that the Assets and Liabilities at the Additional Branches are not
substantially similar in type and character to the Assets and Liabilities
maintained at the Branches other than the Additional Branches. Within 10
calendar days of the receipt by the Seller of such notice, the Seller and the
Buyer shall confer in good faith on a commercially reasonable basis with a view
towards determining a mutually acceptable adjustment to the purchase price to be
paid pursuant to Section 3.1. In the event the Seller and the Buyer are unable
to agree on an acceptable adjustment to the purchase price within such 10 day
period, the matter shall be determined in accordance with Section 9.4.

         (c) As soon as practicable following the delivery of the Additional
Information to the Buyer, Section 3.1 relating to the calculation of the Initial
Base Amount and Schedule 3.1(a) shall be revised to reflect the inclusion of the
Additional Branches.

         (d) There shall not be in effect any nonappealable final order, decree
or judgment of any court or governmental body having competent jurisdiction that
would be violated by consummation of the transactions contemplated hereby, nor
any pending or threatened action, proceeding or investigation, the adverse
determination of which would result in such order, decree or judgment; provided,
that in the case of such pending or threatened action, proceeding or
investigation, neither party shall decline to proceed with the Closing pending
final resolution thereof without exercising its reasonable efforts promptly to
determine jointly with the other party the merit thereof and the likelihood of
an adverse determination in such proceeding.

         Notwithstanding any other provision of this Agreement, in the event
that, at the Closing, there shall be a failure of any condition specified in
this Section 7.2 or elsewhere in this Agreement, including, without limitation,
any failure of condition specified in Section 2.2(e), 2.2(f), 4.3, 4.4, 4.9 or
4.10 to the obligations of the Buyer in respect of the acquisition of any
specific Facility or Facilities, the Buyer nevertheless shall be obligated to

contemplated by this Agreement upon the Closing Date, and the Seller may, upon
written notice to the Buyer, exclude from the Closing the Facility or Facilities

the failure of condition shall exist, in which case, appropriate adjustment
shall be made in the consideration payable pursuant to Article 3, the Schedules
hereto, the Financial Statements and the other documents to be delivered
pursuant hereto so as to duly reflect the deletion of such Facility or
Facilities (but not the other Assets and Liabilities related thereto) from the
Closing.

prior to Closing:

         (a) By the mutual written agreement of the Seller and the Buyer;

         (b) By the Seller or by the Buyer in the event that the Closing has not
 occurred on or before the date indicated in the third proviso in Section
 2.2(a), or such other date as the Seller and the Buyer shall agree in writing,

 Agreement by the party seeking to terminate;

         (c) By the Seller or by the Buyer if consummation of the transactions
 contemplated hereby would violate any nonappealable final order, decree or
 judgment of any court or governmental body having competent jurisdiction;

 however, that (i) termination pursuant to this Section 8.1(d) shall not relieve
 the breaching party of liability for such breach or otherwise and (ii) this
 Section 8.1(d) shall not under any circumstances provide the Buyer with a basis
 for termination due to any actual or alleged breach relating to Hazardous
 Substances, Buyer's sole remedies with respect to Hazardous Substances being
 contained in Section 4.4; and

         (e) By the Seller in the event that:

                  (i) at the expiration of thirty (30) calendar days after the
          date of this Agreement, the Buyer has failed to file substantially
          complete applications requesting approval of the transactions

                  (iii) at the expiration of one hundred fifty (150) calendar
         days after the date of this Agreement, any of the Buyer's Regulatory

Section 8.1(d) or (e), such termination shall be without liability of either
party (or any shareholder, director, officer, employee, agent, consultant or
representative of such party) to the other party to this Agreement, except that,
subject to Section 4.4, if such termination shall result from the willful
failure of a party to fulfill a condition to the performance of the obligations
of the other party or to perform a covenant of this Agreement or from a willful
misrepresentation or breach of a warranty, covenant or agreement hereunder by
either party to this Agreement, such party shall be fully liable for any and all
damages, costs and expenses (including, but not limited to, reasonable
attorney's fees) sustained or incurred by the other party as a result of such
failure or breach.

materials of the other party, including photocopies or other duplications
thereof, relating to this transaction, whether obtained before or after the

                            Survival, Indemnification

         9.1 Survival. The covenants, agreements, representations and warranties
of the parties hereto made, contained in or to be performed pursuant to this
Agreement, the Schedules or Exhibits hereto or the officers' certificates
delivered pursuant hereto or in connection herewith shall survive Closing and
remain operative and in full force and effect until the first anniversary of the
Closing Date, except for the provisions of Sections 2.4, 3.2(i), 4.1(j),
4.4(e)(ii), 4.12, 10.1 and 11.11, which shall survive such first anniversary.
Notwithstanding the preceding sentence, any covenant, agreement, representation,
warranty or claim in respect of which indemnity may be sought under Sections 9.2
or 9.3 shall survive the time at which it would otherwise terminate pursuant to
the preceding sentence if notice of the claim, inaccuracy or breach giving rise
to such right to indemnity shall have been given to the party against whom such
indemnity may be sought prior to such time. After Closing, the sole and
exclusive remedy of the Buyer and the Seller for any breach of any covenant or
agreement or any inaccuracy of any such representation or warranty by the Seller
or the Buyer shall be the indemnities contained in Sections 9.2 and 9.3,
respectively, which shall survive Closing; provided, however, that the
provisions of Section 4.4 shall exclusively govern the rights and obligations of
the Seller and Buyer with regard to Hazardous Substances.

         9.2 Seller's Indemnity. Subject to the proviso in the final sentence of
Section 9.1, the Seller hereby indemnifies the Buyer against and agrees to hold
it harmless from any and all damage, loss, liability and expense (including,
without limitation, reasonable expenses of investigation and attorney's fees and
expenses in connection with any action, suit or proceeding brought against the
Buyer) demanded, claimed or threatened in writing against the Buyer or incurred
or suffered by the Buyer arising out of (i) any action taken or omitted to be
taken by the Seller prior to the Closing relating to the ownership or operation
of the Facilities or their business and properties prior to Closing, but
excluding all Liabilities and any damage, loss, liability or expense resulting
from actions taken by the Seller at the written direction of the Buyer or
resulting from defects in title to the Real Estate; (ii) any misrepresentation
or breach of warranty, covenant or agreement made, contained in or to be
performed by the Seller pursuant to this Agreement, the Schedules or Exhibits
hereto or the Seller's officer's

certificate; (iii) all Non-Assumed Liabilities; and (iv) any claim or demand by
any Branch or Office employee of the Seller who shall not become an employee of
the Buyer (except as may be the result of any action or inaction of the Buyer).
Any direct claim by the Buyer against the Seller, as distinguished from a claim
against the Buyer by a third party, shall be settled by arbitration pursuant to
Section 9.4. The Seller shall not be liable under this Section 9.2 for any
settlement effected without its consent (which consent shall not be unreasonably
withheld) of any claim, litigation or proceeding in respect of which indemnity
may be sought hereunder. The Buyer agrees to give prompt notice to the Seller of
the assertion of any claim, or the commencement of any suit, action or
proceeding in respect of which indemnity may be sought hereunder. The Seller
may, and at the request of the Buyer shall, participate in and control the
defense of any such suit, action or proceeding at its own expense.

         9.3 Buyer's Indemnity. Subject to the proviso in the final sentence of
Section 9.1, the Buyer hereby indemnifies the Seller against and agrees to hold
it harmless from any and all damage, loss, liability and expense (including,
without limitation, reasonable expenses of investigation and attorney's fees and
expenses in connection with any action, suit or proceeding brought against the
Seller) demanded, claimed or threatened in writing against the Seller or
incurred or suffered by the Seller arising out of (i) ownership or operation of
the Facilities or their business and properties on and after Closing (except as
to such damage, liability, loss or expense resulting from actions taken by the
Buyer at the written direction of the Seller); (ii) any misrepresentation or
breach of warranty, covenant or agreement made, contained in or to be performed
by the Buyer pursuant to this Agreement, the Schedules or Exhibits hereto or the
Buyer's officer's certificate; and (iii) all Liabilities (which term excludes
Non-Assumed Liabilities). Any direct claim by the Seller against the Buyer, as
distinguished from a claim against the Seller by a third party, shall be settled
by arbitration pursuant to Section 9.4. The Buyer shall not be liable under this
Section 9.3 for any settlement effected without its consent (which consent shall
not be unreasonably withheld) of any claim, litigation or proceeding in respect
of which indemnity may be sought hereunder. The Seller agrees to give prompt
notice to the Buyer of the assertion of any claim, or the commencement of any
suit, action or proceeding in respect of which indemnity may be sought
hereunder. The Buyer may, and at the request of the Seller shall, participate in
and control the defense of any such suit, action or proceeding at its own
expense.

OF OR RELATING TO THIS AGREEMENT OR ANY AGREEMENTS OR INSTRUMENTS RELATING

THE REQUEST OF ANY PARTY, BE DETERMINED BY ARBITRATION IN ACCORDANCE WITH THE
FEDERAL ARBITRATION ACT (9 U.S.C. SECTION 1 ET SEQ.) UNDER THE AUSPICES AND
RULES OF THE AMERICAN ARBITRATION ASSOCIATION ("AAA"). THE AAA WILL BE
INSTRUCTED BY EITHER OR BOTH PARTIES TO PREPARE A LIST OF THREE PROPOSED
ARBITRATORS. WITHIN TEN (10) CALENDAR DAYS OF RECEIPT OF THE LIST, EACH PARTY
MAY STRIKE ONE (1) NAME FROM THE LIST. THE AAA WILL THEN APPOINT THE ARBITRATOR
FROM THE NAME(S) REMAINING ON THE LIST. THE ARBITRATION WILL BE CONDUCTED IN
ALBUQUERQUE, NEW MEXICO. ANY CONTROVERSY IN INTERPRETATION OR ENFORCEMENT OF
THIS PROVISION OR WHETHER A DISPUTE IS ARBITRABLE, WILL BE DETERMINED BY THE
ARBITRATOR. JUDGMENT UPON THE AWARD RENDERED BY THE ARBITRATOR MAY BE ENTERED IN
ANY COURT HAVING JURISDICTION. THE INSTITUTION AND MAINTENANCE OF AN ACTION FOR
JUDICIAL RELIEF OR IN PURSUIT OF AN ANCILLARY REMEDY DOES NOT CONSTITUTE A
WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE PLAINTIFF, TO SUBMIT THE
CONTROVERSY OR CLAIM TO ARBITRATION.

         (b) IN ANY ARBITRATION PROCEEDING, THE ARBITRATOR IS AUTHORIZED TO
APPORTION COSTS AND EXPENSES, INCLUDING INVESTIGATION, LEGAL AND OTHER EXPENSES,
WHICH WILL INCLUDE, IF APPLICABLE, A REASONABLE ESTIMATE OF ALLOCATED COSTS AND
EXPENSES OF IN-HOUSE LEGAL COUNSEL AND LEGAL STAFF. SUCH COSTS AND EXPENSES ARE
TO BE AWARDED ONLY AFTER THE CONCLUSION OF THE ARBITRATION AND WILL NOT BE
ADVANCED DURING THE COURSE OF SUCH ARBITRATION.

         9.5 Limit on Indemnities.

         (a) Notwithstanding any other provision hereof, an indemnifying party
shall not be liable under this Article 9 or Exhibit H for any losses sustained
by the indemnified party with respect to a Facility unless and until the
aggregate amount of all such losses sustained by the indemnified party with
respect to that Facility (including any amount for which the indemnifying party
may become liable to provide indemnification pursuant to Section 4.4), shall
exceed $30,000, in which event the indemnifying party shall be liable only for
such losses in excess of $30,000 (it being the intention of the parties that
losses sustained by a party with respect to one Facility shall not be combined
with losses sustained with respect to another Facility to satisfy such minimum
$30,000 amount). The minimum $30,000 amount shall not apply to amounts which one
party may be required to pay to the other under Sections 2.4, 3.2, 4.1(g),
4.1(h), 4.6 and 10.1 of this Agreement or other provisions dealing with
customary and foreseeable post-closing adjustments. In no event shall the
aggregate losses for which the Seller may be liable under this Article 9 or
Section 4.4 or any other basis exceed the amount of $5,000,000. IN ADDITION, THE
INDEMNIFYING PARTY SHALL HAVE NO OBLIGATIONS UNDER THIS AGREEMENT FOR ANY
CONSEQUENTIAL LIABILITY, DAMAGE OR LOSS OF THE INDEMNIFIED PARTY THAT THE
INDEMNIFIED PARTY MAY SUFFER.

         (b) Each party's right to indemnification under this Article 9 shall
preclude any other monetary award (whether at law or in equity) and shall
preclude assertion by such party of any right to any such monetary award from
the indemnifying party.

         9.6 Indemnities. Notwithstanding the foregoing, to the extent, if at
all, Section 56-7-1 of NMSA is applicable to this Agreement, the indemnity
provided in this Article 9 will not extend to liability, claims, damages, losses
or expenses, including fees of attorneys, relating to the construction,
installation, alteration, modification, repair, maintenance, servicing,
demolition, excavation, drilling, reworking, grading, paving, clearing, site
preparation or development of any real property or any improvement of any kind
on, above or under real property and arising out of (a) the preparation or
approval of maps, drawings, opinions, reports, surveys, change orders, designs
or specifications by the indemnitee, or the agents or employees of the
indemnitee, or (b) the giving of or the failure to give directions or
instructions by the indemnitee, or the agents or employees of the indemnitee,
where the giving or failure to give directions or instructions is the primary
cause of bodily injury to persons or damage to property.

                                      Taxes

         10.1 Obligations of the Buyer. The Buyer shall pay to the Taxation and
Revenue Department or to Seller, as determined by Seller, and shall indemnify
the Seller for, any gross receipts and compensating tax, any sales tax, use tax,
deed tax or property transfer tax imposed on the sale or transfer of, or
receipts of Seller from the sale or transfer of, the Assets or the Liabilities
or any part thereof.

         10.2 Access to Information. For the applicable period required by law,

the records of the other party relevant to the Assets and the Liabilities and
necessary for the preparation of income tax returns, employee tax returns,
employee reports, employee benefits calculations, and for customary accounting
functions and other similar bona fide purposes. Additionally, the Buyer and the
Seller each agree to make available to the other party, at reasonable times and
upon reasonable advance notice, relevant records and personnel in connection
with an investigation or the preparation of or participation in a defense,
negotiation or settlement relating to any pending, future, or threatened
litigation or government agency proceeding (including a tax audit) involving the
conduct or interest of such other party.

         10.3 Allocation of Consideration. The Buyer and the Seller shall use

for consent or approval of regulatory agencies, contractors and similar third
parties), all oral or written notices or general communications to employees of
the Facilities, and all public announcements and press releases concerning the
transactions contemplated by this Agreement made prior to Closing shall be
jointly planned and coordinated by the Buyer and the Seller. Neither party shall
act unilaterally in this regard without the prior approval of the other party,
which approval shall not be unreasonably withheld or delayed; provided, however,
that in the event that a party reasonably concludes that a public announcement
or release is required by applicable law and the parties cannot reach agreement
upon a mutually acceptable release, the party releasing the information,
announcement or public statement shall not be deemed to be in breach of this
Agreement.

         11.2 Assignment. Neither party shall assign this Agreement or any of
its rights, duties or obligations hereunder without the prior written consent of
the other party, provided that the Seller may assign this Agreement, whether by
merger or other agreement, to an Affiliate; and provided, further, that Buyer
may assign its rights and obligations as contemplated in the sixth Recital to
this Agreement, it being understood that such assignment shall not release Buyer
from any liability to Seller hereunder.

         11.3 Notices. Notices and legal process to be delivered to or served
upon either party hereto shall be deemed to have been duly delivered or served
when delivered in written form by hand or by telegraph, telex or facsimile

         11.7 Entire Agreement. This Agreement embodies the entire agreement and
understanding between the parties hereto and supersedes all prior agreements and
understandings, except that certain Confidentiality Agreement between the

The Confidentiality Agreement shall survive, in accordance with its own terms,
the execution, delivery and performance of this Agreement.

         11.8 Amendment. Neither this Agreement nor any provision hereof may be
changed, waived, discharged or terminated orally. Any such change, waiver,

unenforceability shall not affect any other provision of this Agreement, and
this Agreement shall be construed as if such invalid, illegal or unenforceable
provision were not contained herein.

         11.10 Waiver. No delay or omission to exercise any right, power or
remedy accruing to either party upon any breach or default under this Agreement
shall impair any such right, power or remedy of such party, nor shall it be

therein, or in any similar breach or default thereafter occurring; nor shall any

writing and shall be effective only to the extent specifically set forth in such

         11.11 Confidentiality. The Buyer and its representatives, agents and
designees shall keep confidential and shall not disclose to any person or
entity, without Seller's prior written consent: the amount of the Purchase
Premium, the fact that confidential information has been made available to
Buyer, the existence of this Agreement or any of the terms or conditions hereof,
the status of the transactions contemplated hereby, all information concerning
the books, records, accounts and documents of Seller to which it has access
under this Agreement and any information developed in connection with any
Environmental Assessments that are performed by or on behalf of the Buyer
(including, without limitation, any reports or sampling results and analysis).
These restrictions, however, shall not apply to any such information (i) that
becomes public knowledge through no fault, act or omission of Buyer or its
representatives, agents or designees (for purposes of this Section 11.11,
collectively, the "Buyer"), (ii) that Buyer lawfully acquires from an entity not
under an obligation of confidentiality to Seller, (iii) that is independently
developed by Buyer, or (iv) where the Buyer is legally compelled to disclose
such information, provided that the Seller is provided with advance written
notice of the intention of Buyer to disclose to allow the Seller to contest the
proposed disclosure before any court or agency with jurisdiction unless such
notice impedes a duty or obligation of the Buyer under applicable laws,
regulations or legal requirements to timely report such information, in which
event Buyer shall concurrently advise Seller of Buyer's disclosure. In case of
any actual or purported inconsistency or conflict between the provisions of this
Agreement and the provisions of the Confidentiality Agreement with respect to
obligations of the Buyer to maintain confidentiality as to any information, the
provisions which impose a higher standard of confidentiality on the Buyer with

         medical, dental, vision, life and accidental death and dismemberment
         insurance claims incurred by Employees shall be determined under
         Seller's benefit plans. All medical, dental, vision, life and
         accidental death and dismemberment insurance claims incurred by
         Employees who are in Buyer's employ on the day after the Closing Date
         shall be determined under Buyer's benefit plans beginning on the first
         of the month that begins after the Closing Date occurs. Beginning the

         Employees who are in Buyer's employ on the day after the Closing Date

         periods of coverage under Seller's health or disability plans toward
         satisfying any preexisting condition clause in any of Buyer's health or

         Buyer's health care plans for any deductibles paid by such Employee and
         enrolled dependents for the current plan year under a health care plan
         maintained by Seller."

         since the date of its most recent regulatory evaluation of its
         performance under the CRA; and

         (j) The Buyer has available sufficient cash or other liquid assets or
         financing pursuant to binding agreements or commitments which may be

         capital, obtaining specific financing therefor, consent of any lender
         or any other matter."

                                    ARTICLE 3

                                Employee Services

         3.1 Employee Services. Prior to the Closing Date and ending by the
Closing Date, Seller agrees to loan certain employees ("Loaned Employees") to
Buyer to undertake such activities for Buyer as mutually agreed upon between
Seller and Buyer (the "Employee Training") by the execution of Assignment
Letters in substantially the form attached hereto as Exhibit B (each, an
"Assignment Letter"). Employees of Seller shall not be authorized to participate
in any Employee Training until an Assignment Letter has been executed by Seller
and agreed to by Buyer in accordance herewith. Unless otherwise expressly
provided herein or in an Assignment Letter, if any term or provision contained
in an Assignment Letter conflicts with any other terms or provisions of the
Agreement, such other terms or provisions of the Agreement shall govern.
Further, Seller's obligation hereunder is to use reasonable efforts to make
Employees available to Buyer, without materially affecting the continuing
operations of the Branches and the Offices. Should any Employee's employment
relationship with Seller end for any reason, Seller shall have no obligation to
replace such Employees.


   76

         3.2 Assignment Letter Changes. All changes or modifications to any
Assignment Letter require the prior written approval of Buyer and Seller.

         3.3 Supervision. While a Loaned Employee is being trained by Buyer
hereunder, Buyer will ensure that:

                  (a) Buyer shall supervise and instruct the Loaned Employee
         with regard to the training being provided to the Loaned Employee;

                  (b) Such Loaned Employee shall not be named or act in any way
         in the capacity as an employee of Buyer unless expressly agreed by
         Seller and Buyer in each individual instance in writing;

                  (c) Training performed by a Loaned Employee on behalf of Buyer
         for other Loaned Employees, if requested by Buyer, shall be reviewed by
         Buyer's supervisors on a regular basis;

                  (d) If a Loaned Employee is being trained by Buyer while
         working for Seller, Buyer will cooperate with Seller to balance such
         Loaned Employee's work in a reasonable fashion, consistent with the
         terms of the Assignment Letter; and

                  (e) Buyer and its officers, employees and agents will not
         request or direct any Loaned Employee to disclose to Buyer or any other
         party confidential information of Seller or otherwise direct or
         encourage the Loaned Employee to take any action that would be
         detrimental to Seller, its customers, or otherwise impede or diminish
         the value to Seller of the transactions contemplated by the Agreement.
         In the event that Buyer or its officers, employees or agents gain
         possession of any such confidential information of Seller, Buyer shall
         immediately return such confidential information to Seller. Buyer will
         direct all requests for Seller's confidential information only to those
         officers of Seller who have been designated in writing by Seller as
         authorized contacts.

         3.4 Payment. (a) Unless otherwise specified in an Assignment Letter,
Buyer will pay Seller for Employee Training in an amount equal to the
incremental additional compensation costs for each unit (computed on the basis
of actual FTE usage less FTE budget for the period) incurred by Seller as a
result of each such Loaned Employees' participation in such Employee 


   77

Training for the time during which the Employee Training is being conducted.
Such incremental additional compensation costs shall be computed on the basis of
actual FTE usage less FTE budget for the period multiplied by the blended
average base salary rate for such unit (plus, where applicable, an additional
28% of such base salary rate to cover benefits). Buyer shall not be responsible
for payment for an Employee's absence due to vacation, holidays, illness or
leaves of absence, unless otherwise specified in an Assignment Letter. Seller
will invoice Buyer monthly on net thirty (30) day terms, unless otherwise
specified in the applicable Assignment Letter.

         (b) Travel and Meal Expenses. Loaned Employees will submit travel and
meal expenses incurred by such Loaned Employees as set forth in the Assignment
Letter to Seller for reimbursement, in accordance with Seller's travel policy.
Buyer will reimburse Seller for all such travel and meal expenses, which will be
submitted to Buyer on Seller's monthly invoices.

         3.5      Insurance and Indemnification.

         (a) Scope. With respect to Employee Training and any claims, losses, or
expense arising in connection with the Employee Training, this Section 3.5 shall
control, and Article 9 of the Agreement shall not apply.

         (b) Insurance. Each party shall obtain and maintain at its own expense,
the insurance coverage it deems appropriate to adequately insure itself against
losses arising under this Article 3.

         (c) Expenses and Allocation of Risk of Loss. Prior to the Closing Date,
the following expenses and risks of loss shall be allocated between Buyer and
Seller as follows:

                  (i) Seller shall be responsible for the Loaned Employees'
         salary, benefits, workers' compensation coverage and unemployment
         benefits; and

                  (ii) Buyer shall be responsible for, and Buyer's insurance
         (both on behalf of Buyer and the Loaned Employee) shall answer to any
         losses of Buyer, Seller or any third party arising out of or related to
         any act or omission of a Loaned Employee while involved in Employee
         Training for Buyer.

         (d) Indemnification. Buyer shall indemnify and hold harmless each of
Seller and its employees, officers, directors, representatives, and agents and
each of their respective heirs, personal representatives, successors, and
assigns, from any and all claims, actions, causes of action, demands, liability,
losses, costs and expenses (including court costs and reasonable fees of
attorneys and other professionals, including the 


   78

allocated cost of internal counsel) which (i) are the responsibility of Buyer
under subsections (b) and (c) above, or (ii) arise with respect to any claim by
a Loaned Employee for damages not covered by workers' compensation coverage by a
Loaned Employee arising from any claim of injury incurred or sustained by such
Loaned Employee while involved in Employee Training for the Buyer. Because
Seller is self-insured for workers' compensation purposes, Buyer agrees to
reimburse Seller for out-of-pocket expenses incurred as a result of an injury
sustained by such Loaned Employee while involved in Employee Training for Buyer.

         After receipt by Seller of notice of commencement of any action against
it in respect of which a claim is to be made against Buyer under this Section,
Seller will promptly notify Buyer of the commencement of such action, enclosing
a copy of all papers served, but the omission to so notify Buyer will not
relieve Buyer from any liability that it may have to Seller under the foregoing
provisions of this Article 3 unless, and only to the extent that, such omission
results in the loss of substantive rights or defenses by Buyer. If any such
action is brought against Seller and it notifies Buyer of its commencement,
Buyer will be entitled to participate in and, to the extent that it elects by
delivering written notice to Seller promptly after receiving notice of the
commencement of the action from Seller, to assume the defense of the action,
with counsel reasonably satisfactory to Seller, and after notice from Buyer to
Seller of its election to assume the defense. Buyer will not be liable to Seller
for any legal or other expenses except as provided below and except for the
reasonable costs of investigation subsequently incurred by the Seller in
connection with the defense. Seller will have the right to employ its own
counsel in any such action, but the fees, expenses and other charges of such
counsel will be at the expense of Seller unless (1) the employment of counsel by
Seller has been authorized in writing by Buyer, (2) Seller has reasonably
concluded (based on advice of counsel) that there may be legal defenses
available to it that are different from or in addition to those available to
Buyer, (3) a conflict or potential conflict exists (based on advice of counsel
to Seller) between Seller and Buyer (in which case Buyer will not have the right
to direct the defense of such action on behalf of Seller) or (4) Buyer has not
in fact employed counsel to assume the defense of such action within a
reasonable time after receiving notice of the commencement of the action, in
each of which cases the reasonable fees, disbursements and other charges or
counsel will be at the expense of Buyer. It is understood that Buyer shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the reasonable fees, disbursements and other charges
of more than one separate firm admitted to practice in such jurisdiction at any
one time for Seller. All such fees, disbursements and other charges will be
reimbursed by Buyer promptly as they are incurred. Buyer will 


   79

not be liable for any settlement of any action or claim effected without its
written consent (which consent will not be unreasonably withheld).

         3.6 Termination of Assignment Letter Without Cause. Buyer at its sole
discretion, may elect to terminate any Assignment Letter effective immediately
upon written notice thereof to Seller. Upon receipt of such notice, Seller and
the respective Loaned Employee immediately shall cease all Employee Training
under the applicable Assignment Letter, and Buyer will pay Seller's final
invoice for all Employee Training rendered pursuant to the terminated Assignment
Letter through the date of such termination.

         3.7 Relationship of the Parties. No joint venture, partnership, agency,
employment relationship or other joint enterprise between Seller and Buyer is
contemplated hereby during the training period. No employee of Seller shall be
considered an employee of the Buyer during this training period. Seller shall
take all actions and do all things which are required to ensure that it has
complied with all laws respecting its position as the employer providing
Employee Training pursuant hereto. In performing their respective obligations
under this Article 3, the parties shall act at all times as independent
contractors, and at no time shall either party make any commitments or incur any
charges or expenses for or in the name of the other party.

         3.8 Employment Taxes and Benefits. To the extent required under
applicable law, Seller shall report as income all compensation received by
Seller pursuant hereto and pay all taxes due on such compensation. Seller shall
indemnify and hold harmless Buyer and its employees, officers, directors,
representatives and agents, and their respective heirs, personal
representatives, successors and assigns, from any and all claims, actions,
causes of action, demands, liability, losses, costs and expenses (including
court costs and reasonable fees of attorneys and other professionals) arising
from any obligation imposed on Buyer to pay any withholding taxes, social
security, unemployment insurance, workers' compensation insurance, disability
insurance or similar items, including interest and penalties thereon, in
connection with any payments made to Seller by Buyer pursuant hereto.
